In the existing hand tool market, although there are digital hand tools that help users judge the fastener adjustment situation, they generally need to detect a torque higher than 10Nm to trigger subsequent detection (such as the rotation angle detection of the fastener), so they are not suitable for fastener adjustment scenarios corresponding to low torque.

In view of this, the present invention provides a method for determining the adjustment result of a fastener and an interactive wrench, which can be used to solve the above technical problems.

The embodiment of the present invention provides an interactive wrench, including a wrench body, a pressure sensor, a motion sensor and a processor. The pressure sensor is arranged on the wrench body. The motion sensor is arranged on the wrench body. The processor is disposed on the wrench body and coupled to the pressure sensor and the motion sensor, and is configured to perform: determining a first fastener to be adjusted, wherein the first fastener to be adjusted is assigned a first spatial position and a first specified rotation amount; in response to determining that the pressure sensor detects a first pressure value, controlling the motion sensor to obtain a first current position of the interactive wrench; in response to determining that the first current position of the interactive wrench matches the first spatial position, controlling the motion sensor to obtain a first current rotation amount of the interactive wrench; and determining a first adjustment result of the first fastener to be adjusted, wherein the first adjustment result corresponds to a first comparison result between the first current rotation amount and the first specified rotation amount.

The present invention provides a method for determining a fastener adjustment result, which is suitable for an interactive wrench, including: determining a first fastener to be adjusted, wherein the first fastener to be adjusted is assigned a first spatial position and a first specified rotation amount; in response to determining that a pressure sensor detects a first pressure value, controlling an action sensor to obtain a first current position of the interactive wrench; in response to determining that the first current position of the interactive wrench matches the first spatial position, controlling the action sensor to obtain a first current rotation amount of the interactive wrench; and determining a first adjustment result of the first fastener to be adjusted, wherein the first adjustment result corresponds to a first comparison result between the first current rotation amount and the first specified rotation amount.

Please refer to FIG. 1, which is a schematic diagram of an interactive wrench according to an embodiment of the present invention. In FIG. 1, the interactive wrench 10 includes a wrench body 11, a pressure sensor 12, a motion sensor 13, a processor 14, a communication circuit 15 and a prompt circuit 16.

In one embodiment, a slot 120 may be provided at one end of the wrench body 11, in which a detachable fastener latching portion 130 may be inserted. In this case, the pressure sensor 12 is provided in the slot 120, and the pressure sensor 12 is used to detect the pressure applied to the detachable fastener latching portion 130. In one embodiment, the detachable fastener latching portion 130 may be used to latch a fastener of a corresponding size, thereby driving the latched fastener to rotate when the interactive wrench 10 rotates, but it is not limited to this.

In one embodiment, when the interactive wrench 10 rotates to drive the latched fastener to rotate, the pressure sensor 12 can correspondingly detect that the detachable fastener latching portion 130 is applied with a pressure value higher than a certain value (e.g., 0).

In FIG. 1 , the user can pull out the detachable fastener latch portion 130 from the slot 120 and insert another detachable fastener latch portion corresponding to another fastener size into the slot 120 so that the pressure sensor 12 can detect the pressure applied to the other detachable fastener latch portion.

In one embodiment, the motion sensor 13 may include, for example, a (multi-axis) gyroscope and/or a (multi-axis) accelerometer, and may be used to detect the motion of the interactive wrench 10. In one embodiment, the motion sensor 13 may be implemented as an inertial measurement unit (IMU), but is not limited thereto. In one embodiment, the motion sensor 13 may, for example, perform two integrations on the measured (multi-axis) acceleration values to obtain the position of the interactive wrench 10 in space, but is not limited thereto.

In one embodiment, the communication circuit 15 can exchange data with other electronic devices (such as various smart devices and/or computer devices) based on various communication protocols (such as Bluetooth protocol, fourth generation communication protocol (commonly known as 4G), fifth generation communication protocol (commonly known as 5G) or the like).

In one embodiment, the prompt circuit 16 can be implemented as a component including a display and/or a speaker, which can be controlled by the processor 14 to provide various operation prompts presented in text, light and/or sound, but is not limited thereto.

The processor 14 is coupled to the pressure sensor 12, the motion sensor 13, the communication circuit 15 and the prompt circuit 16, and can be a general-purpose processor, a special-purpose processor, a traditional processor, a digital signal processor, a plurality of microprocessors, one or more microprocessors combined with a digital signal processor core, a controller, a microcontroller, an application-specific integrated circuit (ASIC), a field programmable gate array (FPGA), any other type of integrated circuit, a state machine, an advanced RISC machine (ARM)-based processor, and the like.

In FIG. 1 , the communication circuit 15, the motion sensor 13, and the processor 14 (and the prompt circuit 16) can be integrated into a signal processing device 110, and the signal processing device 110 can be detachably attached to the wrench body 11. In this case, the signal processing device 110 can be removed from the wrench body 11 for charging or other operations. In one embodiment, the wrench body 11 can be provided with contacts corresponding to the signal processing device 110, and can be used to allow the signal processing device 110 to exchange signals with electronic components (such as pressure sensors 12) on the wrench body 11, but it is not limited to this. In other embodiments, all or part of the components on the signal processing device 110 can also be integrated into the wrench body 11, but it is not limited to this.

In an embodiment of the present invention, the processor 14 can access specific modules and program codes to implement the method of determining the fastener adjustment result proposed by the present invention, the details of which are described as follows.

Please refer to FIG. 2, which is a flow chart of a method for determining a fastener adjustment result according to an embodiment of the present invention. The method of the present embodiment can be performed by the interactive wrench 10 of FIG. 1. The following is a description of the details of each step of FIG. 2 with the components shown in FIG. 1. In addition, in order to make the concept of the present invention easier to understand, FIG. 3 is used as an auxiliary explanation below, wherein FIG. 3 is an application scenario diagram according to an embodiment of the present invention.

First, in step S210, the processor 14 determines the first fastener 311 to be adjusted, wherein the first fastener 311 to be adjusted is assigned a first spatial position and a first specified rotation amount.

In different embodiments, the first fastener 311 to be adjusted can be implemented as various screws, nuts and/or bolts. In one embodiment, the first fastener 311 to be adjusted is, for example, a screw that the user should use the interactive wrench 10 to adjust (for example, tighten or loosen), and the first specified rotation amount is, for example, the degree to which the first fastener 311 to be adjusted should be rotated.

In the scenario of FIG. 3, it is assumed that the user needs to sequentially adjust the first fastener to be adjusted 311, the second fastener to be adjusted 312, the third fastener to be adjusted 313, and the fourth fastener to be adjusted 314. In this case, the user can first set the spatial position, designated rotation amount, and/or adjustment sequence of the first fastener to be adjusted 311, the second fastener to be adjusted 312, the third fastener to be adjusted 313, and the fourth fastener to be adjusted 314 on the above electronic device, and the above electronic device sends the setting result to the interactive wrench 10. Based on this, the interactive wrench 10 can determine the spatial position, designated rotation amount, and/or adjustment sequence of each fastener to be adjusted based on the setting result.

In another embodiment, after determining the fastener to be adjusted, the electronic device can send a corresponding fastener adjustment command to the fastener to be adjusted, so that the interactive wrench 10 can determine which fastener to be adjusted by the user using the interactive wrench 10.

For example, assuming that the electronic device determines that the first fastener to be adjusted 311 should be adjusted at the moment, the electronic device can send a first fastener adjustment command to the interactive wrench 10, wherein the first fastener adjustment command can indicate the first fastener to be adjusted 311 and the first spatial position and the first specified rotation amount of the first fastener to be adjusted 311. Accordingly, the processor 14 can determine the first fastener to be adjusted 311 based on the first fastener adjustment command, and obtain the first spatial position and the first specified rotation amount of the first fastener to be adjusted 311 from the first fastener adjustment command, but is not limited to this.

Based on this, the interactive wrench 10 can accordingly determine at what stage/time which fastener to be adjusted should be adjusted, but is not limited to this.

In one embodiment, before the interactive wrench 10 is actually used to adjust the fasteners to be adjusted, a pre-operation may be performed to determine the spatial position of each fastener to be adjusted.

For example, the user may first place the interactive wrench 10 at any position that the user determines to be the origin, and issue an origin reset command to the interactive wrench 10. In this case, the processor 14 may detect the current position of the interactive wrench 10 (control the motion sensor 13) in response to the origin reset command, and determine the current position as the origin position.

In one embodiment, for example, a specific software for controlling the interactive wrench 10 may be run on the electronic device, and the user may trigger a function corresponding to the origin reset command on the specific software to issue an origin reset command to the interactive wrench 10, but the invention is not limited thereto. In one embodiment, the interactive wrench 10 may also be provided with a button corresponding to the origin reset command, and the user may trigger a function corresponding to the origin reset command by pressing the button, thereby issuing an origin reset command to the interactive wrench 10.

In one embodiment, assuming that the user wants to obtain the first spatial position of the first fastener 311 to be adjusted in the pre-operation, the user can move the interactive wrench 10 to the first fastener 311 to be adjusted so that the detachable fastener latching portion 130 latches the first fastener 311 to be adjusted. Afterwards, the user can issue a first position determination command corresponding to the first fastener 311 to be adjusted to the interactive wrench 10 through the above-mentioned specific software. In this case, the processor 14 can detect the first position of the interactive wrench 10 relative to the above-mentioned origin position (control the motion sensor 13) in response to the first position determination command, and determine the first position as the first spatial position of the first fastener 311 to be adjusted.

In one embodiment, the processor 14 can also determine the orientation of the wrench body 11 in response to the above-mentioned first position determination command, and determine this orientation as the orientation of the first fastener 311 to be adjusted.

From another point of view, the first spatial position (and orientation) can be understood as the position (and orientation) that should correspond when the interactive wrench 10 correctly engages the first fastener 311 to be adjusted. In other words, when the future position (and orientation) of the interactive wrench 10 is determined to correspond to the first spatial position (and orientation) of the first fastener 311 to be adjusted, it means that the interactive wrench 10 has correctly engaged the first fastener 311 to be adjusted, but it is not limited to this.

In addition, when the user wants to obtain the second spatial position of the second fastener 312 to be adjusted in the aforementioned pre-operation, the user can move the interactive wrench 10 to the second fastener 312 to be adjusted so that the detachable fastener latching portion 130 latches the second fastener 312 to be adjusted. Afterwards, the user can issue a second position determination command corresponding to the second fastener 312 to be adjusted to the interactive wrench 10 through the aforementioned specific software, for example. In this case, the processor 14 can detect the second position (and orientation) of the interactive wrench 10 relative to the aforementioned origin position (control the motion sensor 13) in response to the second position determination command, and determine the second position as the second spatial position (and orientation) of the second fastener 312 to be adjusted.

From another point of view, the second spatial position can be understood as the position (and orientation) that the interactive wrench 10 should correspond to when it correctly engages the second fastener 312 to be adjusted. In other words, when the future position of the interactive wrench 10 is determined to correspond to the second spatial position (and orientation) of the second fastener 312 to be adjusted, it means that the interactive wrench 10 has correctly engaged the second fastener 312 to be adjusted, but it is not limited to this.

Based on the above teachings, a person with ordinary knowledge in the art should be able to understand the method of obtaining the third spatial position (and orientation) of the third fastener 313 to be adjusted and the fourth spatial position (and orientation) of the fourth fastener 314 to be adjusted in the above-mentioned pre-operation, which will not be further described here.

In one embodiment, after determining that the fastener to be adjusted is the first fastener to be adjusted 311, the processor 14 may provide a first movement prompt corresponding to the first fastener to be adjusted 311, wherein the first movement prompt may indicate to move the interactive wrench 10 toward the first fastener to be adjusted and to engage the first fastener to be adjusted 311. In one embodiment, the processor 14 may control the prompt circuit 16 to present the first movement prompt in the form of sound and/or text to prompt the user to move the interactive wrench 10 toward the first fastener to be adjusted and engage the first fastener to be adjusted 311. In another embodiment, the first movement prompt may also be provided by an electronic device, but is not limited thereto.

Next, assume that the user has correctly engaged the first fastener 311 to be adjusted using the interactive wrench 10 and rotated the first fastener 311 accordingly. At this time, the pressure sensor 12 will correspondingly detect a pressure value (hereinafter referred to as the first pressure value) higher than a certain value (e.g., 0) on the first fastener 311 to be adjusted.

Based on this, in step S220, in response to determining that the pressure sensor 12 detects the first pressure value, the processor 14 controls the motion sensor 13 to obtain the first current position of the interactive wrench 10.

In one embodiment, the processor 14 can determine whether the first current position of the interactive wrench 10 matches the first spatial position of the first fastener 311 to be adjusted. If so, it means that the interactive wrench 10 has correctly engaged the first fastener 311 to be adjusted, so step S230 can be continued.

On the other hand, if the first current position of the interactive wrench 10 does not match the first spatial position of the first fastener 311 to be adjusted, this means that the interactive wrench 10 does not correctly engage the first fastener 311 to be adjusted (for example, it is engaging the second fastener 312 to be adjusted). In this case, the processor 14 can control the prompt circuit 16 to provide a position error prompt in the form of text and/or sound, so that the user can make corresponding corrections, but it is not limited to this.

In one embodiment, in response to determining that the pressure sensor 12 detects a first pressure value, the processor 14 further controls the motion sensor 13 to obtain the orientation of the wrench body 11. For example, the processor 14 can determine the tilt angle of the wrench body 11 in three-dimensional space as the orientation of the wrench body 11 based on the sensing data provided by the motion sensor 13, but is not limited thereto.

In one embodiment, the first fastener 311 to be adjusted may also have its own orientation. In the scenario of FIG. 3 , the orientation of the first fastener 311 to be adjusted is, for example, horizontal. In this case, the processor 14 may also determine whether the orientation of the wrench body 11 matches the orientation of the first fastener 311 to be adjusted. If the first current position of the interactive wrench 10 does not match the first spatial position of the first fastener 311 to be adjusted, or the orientation of the wrench body 11 matches the orientation of the first fastener 311 to be adjusted, it means that the interactive wrench 10 has correctly engaged the first fastener 311 to be adjusted, and therefore step S230 may be continued.

In step S230, in response to determining that the first current position of the interactive wrench 10 matches the first spatial position, the processor 14 controls the motion sensor 13 to obtain the first current rotation amount of the interactive wrench 10.

In one embodiment, the processor 14 can determine the first current rotation amount of the interactive wrench 10 based on the data detected by the gyroscope in the motion sensor 14, for example.

In one embodiment, in response to determining that the first current position of the interactive wrench 10 matches the first spatial position, the processor 14 may accumulate the first accumulated rotation amount applied by the interactive wrench 10 to the first fastener 311 to be adjusted based on the motion sensing data provided by the motion sensor 13, and use the first accumulated rotation amount as the first current rotation amount. That is, the processor 14 may start accumulating the rotation amount after determining that the interactive wrench 10 has correctly engaged the first fastener 311 to be adjusted and rotated the first fastener 311 to be adjusted, and use the accumulated rotation amount as the first current rotation amount, but is not limited thereto.

In one embodiment, in response to determining that the first current position of the interactive wrench 10 matches the first spatial position, the processor 14 can also control the motion sensor 13 to obtain the current rotation direction corresponding to the first current rotation amount. Based on this, the first current rotation amount determined by the processor 14 can be understood as the cumulative rotation amount in the current rotation direction.

Taking the scenario of FIG. 3 as an example, assuming that the interactive wrench 10 rotates 30 degrees clockwise when it is locked in the first screw 311 to be adjusted, the processor 14 can determine that the current rotation direction is clockwise, and the first current rotation amount is 30 degrees. For another example, assuming that the interactive wrench 10 rotates 60 degrees counterclockwise when it is locked in the first screw 311 to be adjusted, the processor 14 can determine that the current rotation direction is counterclockwise, and the first current rotation amount is 60 degrees, but it is not limited to this.

Next, in step S240, the processor 14 determines the first adjustment result of the first fastener 311 to be adjusted, wherein the first adjustment result corresponds to the first comparison result between the first current rotation amount and the first specified rotation amount.

In an embodiment of the present invention, the processor 14 may, for example, obtain the difference between the first current rotation amount and the first designated rotation amount as the first comparison result. In another embodiment, the first designated rotation amount is, for example, the rotation amount in a designated direction, and the processor 14 may, for example, obtain the difference between the first current rotation amount and the first designated rotation amount and the consistency between the designated direction and the current rotation direction as the first comparison result.

In the first embodiment, in response to determining that the first comparison result indicates that the first current rotation amount is less than the first specified rotation amount, the processor 14 may determine that the first adjustment result indicates that the first current rotation amount is insufficient. In addition, in response to determining that the first comparison result indicates that the first current rotation amount is greater than the first specified rotation amount, the processor 14 may determine that the first adjustment result indicates that the first current rotation amount is excessive. Furthermore, in response to determining that the first comparison result indicates that the first current rotation amount is equal to the first specified rotation amount, the processor 14 may determine that the first adjustment result indicates that the first current rotation amount is appropriate.

In addition, in another embodiment, in response to determining that the first comparison result indicates that the first current rotation amount is less than the first specified rotation amount, and the current rotation direction matches the specified direction, the processor 14 may determine that the first adjustment result indicates that the first current rotation amount is insufficient. In addition, in response to determining that the first comparison result indicates that the first current rotation amount is greater than the first specified rotation amount, or the current rotation direction does not match the specified direction, the processor 14 may determine that the first adjustment result indicates that the first current rotation amount is excessive. Furthermore, in response to determining that the first comparison result indicates that the first current rotation amount is equal to the first specified rotation amount, the processor 14 may determine that the first adjustment result indicates that the first current rotation amount is appropriate.

In the second embodiment, in response to determining that the difference between the first comparison result indicating the first current rotation amount and the first designated rotation amount is not greater than a preset threshold, the processor 14 may determine that the first adjustment result indicates that the first current rotation amount is appropriate. On the other hand, in response to determining that the difference between the first comparison result indicating the first current rotation amount and the first designated rotation amount is greater than the preset threshold, the processor 14 determines that the first adjustment result indicates that the first current rotation amount is inappropriate.

In addition, in another embodiment, in response to determining that the difference between the first comparison result indicating the first current rotation amount and the first specified rotation amount is not greater than a preset threshold, and the current rotation direction matches the specified direction, the processor 14 may determine that the first adjustment result indicates that the first current rotation amount is appropriate. On the other hand, in response to determining that the difference between the first comparison result indicating the first current rotation amount and the first specified rotation amount is greater than the preset threshold, or the current rotation direction does not match the specified direction, the processor 14 determines that the first adjustment result indicates that the first current rotation amount is inappropriate.

In one embodiment, the processor 14 may also control the prompt circuit 16 to provide a corresponding operation prompt in response to the first adjustment result of the first fastener to be adjusted.

For example, in response to determining that the first adjustment result indicates that the first current rotation amount is inappropriate (e.g., too much or too little), the processor 14 may provide a first rotation correction indication based on the first comparison result.

For example, if the first adjustment result indicates that the first current rotation amount is less than the first specified rotation amount by 15 degrees, the processor 14 may control the prompt circuit 16 to provide a corresponding first rotation correction indication as an operation prompt. For example, the processor 14 may control the prompt circuit 16 to prompt the user in a voice/text manner to rotate the first to-be-adjusted fastener 311 by an additional 15 degrees (along the specified direction), but is not limited thereto.

For another example, if the first adjustment result indicates that the first current rotation amount is greater than the first specified rotation amount by 3 degrees, the processor 14 may control the prompt circuit 16 to provide a corresponding first rotation correction indication as an operation prompt. For example, the processor 14 may control the prompt circuit 16 to prompt the user to rotate the first to-be-adjusted fastener 311 by 3 degrees in the opposite direction in a voice/text manner, but is not limited thereto.

In addition, in response to determining that the first adjustment result indicates that the first current rotation amount is appropriate, the processor 14 can control the prompt circuit 16 to provide a prompt corresponding to the adjustment completion of the first fastener 311 to be adjusted in text/sound, so that the user knows that the adjustment of the first fastener 311 to be adjusted has been completed, but it is not limited to this.

As mentioned above, since the user is assumed to need to adjust the first fastener to be adjusted 311, the second fastener to be adjusted 312, the third fastener to be adjusted 313 and the fourth fastener to be adjusted 314 in sequence, after the adjustment of the first fastener to be adjusted 311 is completed (for example, the first adjustment result indicates that the first current rotation amount is appropriate), the processor 14 can continue to execute steps S250-S280 to assist the user in adjusting the second fastener to be adjusted 312.

In step S250, the processor 14 determines the second fastener 312 to be adjusted, wherein the second fastener 312 to be adjusted is assigned a second spatial position and a second specified rotation amount. In this case, the second fastener 312 to be adjusted is the fastener that the user should use the interactive wrench 10 to adjust (e.g., tighten or loosen), and the second specified rotation amount is, for example, the degree to which the second fastener 312 to be adjusted should be rotated.

In the embodiment of the present invention, the method by which the processor 14 determines the second fastener 312 to be adjusted may be similar to the method by which the first fastener 311 to be adjusted is determined, so the details may refer to the description in the previous embodiment and will not be further described here.

In one embodiment, after determining the second fastener to be adjusted, the processor 14 may also (control the prompt circuit 16) provide a second movement prompt corresponding to the second fastener 312 to be adjusted, wherein the second movement prompt (for example, presented in voice/text) indicates to move the interactive wrench 10 toward the second fastener 312 to be adjusted.

Based on this, the user can move the interactive wrench 10 toward the second fastener 312 to be adjusted according to the second movement prompt, and rotate the second fastener 312 to be adjusted after locking the second fastener 312 with the detachable fastener locking portion 130.

At this time, the pressure sensor 12 will correspondingly detect a pressure value (hereinafter referred to as the second pressure value) higher than a certain value (for example, 0) on the second fastener 312 to be adjusted.

Based on this, in step S260, in response to determining that the pressure sensor 12 detects the second pressure value, the processor 14 controls the motion sensor 13 to obtain the second current position of the interactive wrench 10.

In one embodiment, the processor 14 can determine whether the second current position of the interactive wrench 10 matches the second spatial position of the second fastener 312 to be adjusted. If so, it means that the interactive wrench 10 has correctly engaged the second fastener 312 to be adjusted, so step S270 can be continued.

On the other hand, if the second current position of the interactive wrench 10 does not match the second spatial position of the second fastener 312 to be adjusted, this means that the interactive wrench 10 does not correctly engage the second fastener 312 to be adjusted (for example, it is engaging the second fastener 312 to be adjusted). In this case, the processor 14 can control the prompt circuit 16 to provide a position error prompt in the form of text and/or sound, so that the user can make corresponding corrections, but it is not limited to this.

In step S270, in response to determining that the second current position of the interactive wrench 10 matches the second spatial position, the processor 14 controls the motion sensor 13 to obtain the second current rotation amount of the interactive wrench 10.

In one embodiment, the processor 14 can determine the second current rotation amount of the interactive wrench 10 based on the data detected by the gyroscope in the motion sensor 14, for example.

In one embodiment, in response to determining that the second current position of the interactive wrench 10 matches the second spatial position, the processor 14 may accumulate the second accumulated rotation amount applied by the interactive wrench 10 to the second fastener 312 to be adjusted based on the motion sensing data provided by the motion sensor 13, and use the second accumulated rotation amount as the second current rotation amount. That is, the processor 14 may start accumulating the rotation amount after determining that the interactive wrench 10 has correctly engaged the second fastener 312 to be adjusted and rotated the second fastener 312 to be adjusted, and use the accumulated rotation amount as the second current rotation amount, but is not limited thereto.

In step S280, the processor 14 determines the second adjustment result of the second to-be-adjusted fastener 312, wherein the second adjustment result corresponds to the second comparison result between the second current rotation amount and the second specified rotation amount.

14例如可依據先前判定第一調整結果指示第一當下旋轉量為恰當/不恰當的方式來判定第二調整結果對應的第二當下旋轉量為恰當/不恰當，並提供對應的操作提示(例如旋轉修正提示)。相關說明可參照先前實施例的內容，於此不另贅述。 In an embodiment of the present invention, the processing

For example, the second adjustment result may be determined to be appropriate/inappropriate based on the way in which the first adjustment result indicates that the first current rotation amount is appropriate/inappropriate, and a corresponding operation prompt (such as a rotation correction prompt) may be provided. For the related description, please refer to the content of the previous embodiment, which will not be elaborated here.

In addition, in response to determining that the first adjustment result indicates that the second current rotation amount is appropriate, the processor 14 can control the prompt circuit 16 to provide a prompt corresponding to the second to-be-adjusted fastener 313 in text/sound to let the user know that the adjustment of the second to-be-adjusted fastener 312 has been completed, but is not limited thereto.

As mentioned previously, since the user is assumed to need to adjust the first fastener to be adjusted 311, the second fastener to be adjusted 312, the third fastener to be adjusted 313 and the fourth fastener to be adjusted 314 in sequence, after the adjustment of the second fastener to be adjusted 312 is completed (for example, the second adjustment result indicates that the second current rotation amount is appropriate), the processor 14 can continue to execute corresponding steps similar to steps S210~S240 (or steps S250~S280) to assist the user in adjusting the third fastener to be adjusted 313. Furthermore, after completing the adjustment of the third fastener 313 to be adjusted, the processor 14 may continue to execute corresponding steps similar to steps S210-S240 (or steps S250-S280) to assist the user in adjusting the fourth fastener 314 to be adjusted.

As can be seen from the above, the interactive wrench 10 proposed by the present invention can detect whether the user is rotating the object it is clamping with the interactive wrench 10 through a pressure sensor. When the pressure sensor detects a pressure value higher than a certain value, the interactive wrench 10 can further determine whether the current position of the interactive wrench 10 matches the spatial position of the fastener that should be adjusted at the moment. If so, the interactive wrench 10 can further determine whether the current rotation amount matches the specified rotation amount corresponding to the currently clamped fastener, and determine the adjustment result corresponding to this fastener accordingly.

Thus, the interactive wrench 10 can be used to assist the user to sequentially complete the adjustment of each fastener to be adjusted. In addition, the interactive wrench 10 can also provide corresponding operation prompts (such as movement prompts, rotation correction prompts, and/or adjustment completion prompts) for the user's reference in a timely manner to improve the accuracy and efficiency of the user's adjustment of the fastener.

In some embodiments, when performing steps S210-S240 corresponding to the first fastener 311 to be adjusted, part or all of them may also be performed by the above-mentioned electronic device.

In one embodiment, the electronic device can determine the first fastener 311 to be adjusted (corresponding to step S210) according to the user's setting result, and notify the interactive wrench 10 accordingly.

In one embodiment, when the interactive wrench 10 detects the first pressure value, the electronic device can be notified accordingly, and the electronic device controls the motion sensor 13 through the corresponding control signal to obtain the first current position of the interactive wrench 10 (which corresponds to step S220).

In one embodiment, after the interactive wrench 10 obtains the first current position, the first current position of the interactive wrench 10 can be sent to the above-mentioned electronic device through the communication circuit 15, so that the electronic device can determine whether the first current position of the interactive wrench 10 matches the first spatial position of the first fastener 311 to be adjusted. After the electronic device completes the judgment, it can send a corresponding signal to the interactive wrench 10 (which corresponds to step S230), so that the interactive wrench 10 can determine whether the first current position of the interactive wrench 10 matches the first spatial position of the first fastener 311 to be adjusted, and perform corresponding operations (for example, providing a position error prompt, or controlling the motion sensor 13 to continue to detect the first current rotation amount of the interactive wrench 10).

In one embodiment, after the processor 14 obtains the first current rotation amount of the interactive wrench 10, the processor 14 can send the first current rotation amount of the interactive wrench 10 to the above-mentioned electronic device through the communication circuit 15, so that the electronic device can determine the first adjustment result of the first fastener 311 to be adjusted (which corresponds to step S240). Afterwards, the electronic device can control the interactive wrench 10 to provide corresponding operation prompts based on the first adjustment result, but it is not limited to this.

In short, in different embodiments, the processor 14 may send at least one of the first current position, the first current rotation amount, the first comparison result, and the first adjustment result to the electronic device so that the electronic device can make a corresponding determination, but it is not limited thereto.

In one embodiment, after obtaining the first adjustment result of the first fastener to be adjusted, the processor 14 may also send the first adjustment result to the electronic device so that the electronic device can perform subsequent operations (such as continuing to determine the second fastener to be adjusted, etc.), but it is not limited to this.

In different embodiments, when performing steps S210-S240 corresponding to the first fastener 311 to be adjusted, the interactive wrench 10 and the electronic device may each perform a portion of steps S210-S240. For example, the interactive wrench 10 may perform step S210, and the electronic device may perform steps S220-S240. Alternatively, the electronic device may perform step S210, and the interactive wrench 10 may perform steps S220-S240. In addition, the interactive wrench 10 may also perform steps S210 and S230, and the electronic device may perform steps S220 and S240. The designer can assign the interactive wrench 10 and the electronic device to perform which parts of steps S210~S240 according to the needs, and is not limited to the above examples.

In addition, when performing steps S250-S280 corresponding to the second fastener 312 to be adjusted (and the adjustment steps corresponding to other fasteners to be adjusted), part or all of them can also be performed by the above-mentioned electronic device. The concept can refer to the description of the above embodiment and will not be further described here.

In summary, the interactive wrench proposed in the present invention can detect whether the user is rotating the object it is clamping with the interactive wrench through a pressure sensor. When the pressure sensor detects a pressure value higher than a certain value (such as 0), the interactive wrench can further determine whether the current position of the interactive wrench matches the spatial position of the fastener to be adjusted at the moment. If so, the interactive wrench can further determine whether the current rotation amount matches the specified rotation amount corresponding to the currently clamped fastener, and determine the adjustment result corresponding to this fastener accordingly. Therefore, even in a low-torque usage scenario, the interactive wrench can still be used to assist the user to complete the adjustment of each fastener to be adjusted in sequence.

In addition, the interactive wrench can also provide corresponding operation prompts (such as movement prompts, rotation correction prompts, and/or adjustment completion prompts) for the user's reference in a timely manner to improve the user's accuracy and efficiency in adjusting fasteners.

Although the present invention has been disclosed as above by the embodiments, it is not intended to limit the present invention. Anyone with ordinary knowledge in the relevant technical field can make some changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be subject to the scope of the attached patent application.
