In a specific implementation, the driving mechanism can be implemented in various manners, for example, a magnetic driving mechanism, a traction mechanism, a screw mechanism, a rack and pinion mechanism, etc., and the following describes the structure and principle of the above several implementation modes:

1. The driving mechanism is realized by a magnetic driving component. The magnetic driving component comprises an electromagnet and an armature. By controlling the on-off and polarity change of the electromagnet, the two electromagnets are attracted or repelled, or an electromagnet is An armature attracts or repels between the armatures to control the movement of the connection end connected to the electromagnet or the armature;

By controlling the on/off or polarity change of the electromagnet, the magnetic driving members 221 and 223 can be arranged along the same as shown in FIG. 2a. The arrows A and B move to drive the connecting end 11 or 12 to move, thereby adjusting the distance between the two connecting ends.

In the above arrangement, any one of the magnetic driving members 221, 223 can be omitted, that is, one connecting end is directly connected to the buckle body 21, and the magnetic driving member only drives one connecting end to move.

Another arrangement manner is shown in FIG. 2b, in which two magnetic driving members 221 are movably disposed in the buckle body 21, 222, wherein the magnetic driving members 221 and 222 are all electromagnets and are respectively connected to one connecting end, and the movement principle thereof is the same as the above-mentioned setting manner, and details are not described herein again.

When the driving mechanism adopts the magnetic driving member, the armature that cooperates with the electromagnet can be a permanent magnet material, such as a magnet, and the electromagnet can be moved toward or away from the armature by controlling the polarity change of the electromagnet to tighten the fixing strap body. Or relax; the armature can also be made of a soft magnetic material, such as a ferroalloy material. The electromagnet moves toward the armature after being energized and cannot be automatically reset after the power is turned off.

Improve the user experience.

Example twelve

The embodiment of the present invention describes a control method of the wearable device provided by the embodiment of the present invention in combination with a specific application scenario. The wearable device products used in the following application scenarios all take the smart watch as an example, and all adopt the fixing tape provided in the foregoing third embodiment. , that is, a fixing belt driven by an electromagnet, and the control mechanism of the fixing belt is disposed in the smart watch, and the user can control the fixing belt through a smart watch or a related application installed in the mobile phone connected with the smart watch; the smart watch The back cover portion is provided with a sensor for detecting the heart rate and blood pressure of the user.

When the user needs to measure heart rate and blood pressure, for example, when the user wears the smart watch and performs exercise, such as running, riding, mountain climbing, swimming, etc., the user needs to know his heart rate and blood pressure with exercise time and exercise distance. Or the corresponding change caused by the change of altitude, the corresponding sports monitoring application is installed in the smart watch, the application can perform heart rate and blood pressure measurement according to a predetermined time interval, and the heart rate and blood pressure measurement can also be performed according to the predetermined exercise distance. Heart rate and blood pressure measurements can be made according to a predetermined altitude change; of course, a single heart rate or blood pressure measurement can be performed according to the user's instructions.

After the user wears the smart watch, by adjusting the first connecting portion and the second connecting portion of the buckle body, the circumference of the annular structure enclosed by the fixing belt body is at a proper wearing length, and is not too loose and too tight. And in the application of the smart watch, arbitrarily select the automatic measurement of heart rate and blood pressure according to the predetermined time interval, the change of the movement distance, the change of the altitude, and start the exercise; then the application according to the predetermined time interval, the predetermined movement distance The change, the predetermined altitude change, the drive information is sent to the drive mechanism, and the drive mechanism is controlled to adjust the circumferential change of the annular structure enclosed by the fixed belt body.

Specifically, taking the measurement at a predetermined time interval as an example, firstly, the user selects the blood pressure and heart rate measurement according to the time interval in the application, and selects the required time interval, for example, 5 minutes, 10 minutes, etc., and then selects the start. The measured time, for example, the measurement is started immediately, or after a predetermined time, after the user reaches the predetermined position, etc.; after the measurement process starts, the application starts timing, and when the preset time interval is reached, the application Sending control information for controlling the tightening of the fixed strap body to the driving mechanism, that is, energizing the electromagnet in the driving mechanism, the fixing strap body is tightened, the sensor disposed on the back cover of the smart watch is closely attached to the wrist of the user, and the heart rate is started. The blood pressure is detected, and the heart rate and blood pressure information are sent to the application. After acquiring the heart rate and blood pressure information, the application sends control information to the driving mechanism to control the relaxation of the fixed body, even if the electromagnet in the driving mechanism is powered off. The strap body is relaxed to complete a detection process; the application can be based on multiple times Measurement results acquired user's heart rate, blood pressure changes with the movement of the process time, and generates data so that the user knows heart rate, blood pressure changes with the movement time.

The process of measuring the movement distance change and the altitude change according to the predetermined distance is the same as the above-mentioned measurement according to the predetermined time interval, and the application program can be set according to the positioning module set in the smart watch or the terminal device connected with the smart watch. The positioning module acquires the location information of the user to calculate the movement distance and altitude change of the user, thereby obtaining a change process of the user's heart rate, blood pressure with the movement distance, and altitude.

A pressure sensor for detecting the pressure generated by the fixed strap body on the wrist of the user may also be provided in the back cover or the fixing strap of the wearable device. Specifically, the back cover may be a contact surface of the wearable device except the fixing band and the wrist of the user. Optionally, a suitable pressure threshold can be preset in the application. In the above measurement process, when the fixing strap is tightened, the pressure sensor detects that the pressure of the fixing belt body on the wrist of the user reaches a preset pressure. When the threshold is reached, the control mechanism controls the driving mechanism to no longer move, so that the fixing strap body is not further tightened, so as to avoid over-tightening the user's wrist and causing discomfort, specifically by adjusting the current in the coil of the electromagnet.

In addition to the above-mentioned automatic measurement method to detect the user's heart rate and blood pressure, it can also be detected by means of manual control of the drive mechanism according to the user's needs. The control switch of the control drive mechanism is set in the application program, and the user opens when there is a measurement demand. An application installed in the wearable device, or an application installed in the mobile phone connected to the wearable device, and clicking the control switch, the application can send control information to the drive mechanism, so that the drive mechanism drives the fixed strap body to tighten Or relax.

Different control information can be set in the application according to the heart rate measurement and the blood pressure measurement, respectively, and the movement mechanism of the driving mechanism corresponding to the two kinds of control information is different, so that the sensor of the smart watch has the wrist and the user's wrist when performing heart rate measurement and blood pressure measurement. Different fit tightness can improve the accuracy of the smart watch when performing heart rate measurement and blood pressure measurement.

When the user does not have heart rate and blood pressure measurement requirements, the smart watch can also prompt the user by controlling the tightening-relaxation of the strap. Specifically, when the wearable device detects the prompt message, the control mechanism controls the driving mechanism to open, so that the fixing strap body is tightened, thereby prompting the user; optionally, the fixing strap body can be tightened multiple times, or tightened Relax afterwards, or relax and repeat as many times as you tighten. The above prompt messages are various, such as system messages of wearable devices, application messages, or mobile phone system messages connected to wearable devices, application messages, and the like. For example, when a user sends or receives a mail through a smart watch or a mobile phone or tablet connected to a smart watch, in the application for sending and receiving mail, the prompt of the mail of the important contact is set to the tightening-relaxing of the fixed belt body. The prompt, when the mail receiving and receiving application receives the mail of the important contact, sends a tightening and loosening control information to the driving mechanism at a certain frequency, so that the fixing is regularly tightened and relaxed to prompt the user to check the mail; The prompt mode is different from the common sound, vibration, and display prompts, which improves the interaction performance between the smart watch and the user.

It is apparent that those skilled in the art can make various modifications and variations to the embodiments of the invention without departing from the spirit and scope of the invention. Thus, it is intended that the present invention cover the modifications and modifications of the invention
