Referring to FIGS. 1-3 , the present application provides a centrifugal motor 100 , the centrifugal motor 100 can generate centrifugal force, so that the device on which the centrifugal motor 100 is installed can adjust the angle under the action of the centrifugal force. The centrifugal motor 100 includes a limiter 10 , a fixed sleeve 20 rotatably connected to the limiter 10 , a rotating block 30 partially accommodated in the fixed sleeve 20 , and an elastic member 40 disposed between the fixed sleeve 20 and the rotating block 30 . and the magnetic coil 50 fixedly connected to the periphery of the limiting member 10 .

Specifically, in one embodiment, the stopper 10 is provided with an outlet 12 , the fixing sleeve 20 is elongated, such as cylindrical, and is rotatably sleeved in the outlet 12 of the stopper 10 , so that the fixing sleeve 20 is under the action of external force. The lower part can rotate relative to the limiter 10 . The fixing sleeve 20 forms an accommodating cavity, and the fixing sleeve 20 defines an opening 22 that communicates with the accommodating cavity. The rotating block 30 is a magnetic body, such as a metal block, a permanent magnet, or a permanent magnet, etc., inside the rotating block 30, most of which are accommodated in the accommodating cavity of the fixed sleeve 20, and a part is located outside the opening 22, so that the rotating block 30 The center of gravity is deviated from the axis of the fixed sleeve 20 . The elastic member 40 is arranged between the inner wall of the accommodating cavity enclosed by the fixed sleeve 20 and the rotating block 30. It can be understood that the elastic member 40 in this embodiment is a spring, and in other embodiments, the elastic member 40 can also be an elastic column, etc. other elastic parts. The magnetic coil 50 is fixedly connected to the periphery of the limiter 10 , specifically, it can be connected to the limiter 10 , or can be fixed to the periphery of the limiter 10 through other auxiliary parts independent of the limiter 10 , as shown in FIG. 4 . In the case of the limiting member 10, the magnetic coil 50 is used to generate a magnetic force to act on the rotating block 30, so that the rotating block 30 rotates and drives the fixed sleeve 20 to rotate. The specific magnetic force generated by the magnetic coil to the rotating block is a repulsive force.

Specifically, in different embodiments, the repulsive force generated by the magnetic coil 50 to the rotating block 30 is a periodic pulse force, and the duration of the pulse force is consistent with the time when the rotating block 30 is partially located outside the opening. The ring 50 may also generate a repulsive force against the rotating block 30 all the time.

At the same time with reference to FIG. 4 , the following explains the cooperation process between the various components during the rotation of the rotating block 30 : the magnetic coil 50 generates a magnetic force to act on the rotating block 30 , and the direction of the magnetic force is shown in the direction a in FIG. 4 , so that the rotation The block 30 rotates and drives the fixed sleeve 20 to rotate; the part of the rotating block 30 located outside the opening 22 abuts against the limiting member 10, so that the limiting member 10 squeezes the rotating block 30, thereby causing the rotating block 30 to compress the elastic member 40 and move toward the fixed sleeve 20, so that the center of gravity of the rotating block 30 coincides with the axis of the fixed sleeve 20. During this process, the elastic member 40 is compressed. It is understandable that when the rotating block 30 is located outside the opening 22, the elastic member 40 is in an extended state. The rotating block 30 is kept partially outside the opening 22 . The rotating block 30 and the fixed sleeve 20 continue to rotate due to inertia, so that the opening 22 of the fixed sleeve 20 is opposite to the outlet 12 of the limiting member 10 again, so that the rotating block 30 is not restricted by the limiting member 10, and the elastic member 40 is stretched again so that The rotating block 30 is again partially located outside the opening 22, and so on. In the above process, as long as the rotating block 30 is partially located outside the opening 22, the center of gravity of the rotating block 30 deviates from the axis line of the fixed sleeve 20, thereby generating centrifugal force.

Assuming that the time for one rotation of the rotating block 30 is one cycle, a part of the rotating block 30 is located outside the opening 22 in a part of the time during one rotation of the rotating block 30 . It can be understood that in the process of pressing the rotating block 30 against the limiting member 10, the rotating block is gradually retracted into the accommodating cavity of the fixing sleeve 20. Therefore, during this process, the volume of the rotating block 30 outside the opening 22 will be reduced. change gradually. When the rotating block 30 is partially located outside the opening 22 of the fixed sleeve 20, the center of gravity of the rotating block 30 does not coincide with the axis of the fixed sleeve 20, and the eccentric rotation of the rotating block 30 will generate a centrifugal force. Then the electronic device using the above centrifugal motor 100 can cause the magnetic coil 50 to generate a magnetic force to act on the rotating block 30 to rotate during the process of detecting the drop of the electronic device, and use the centrifugal force generated by the centrifugal motor 100 to adjust the angle of the electronic device so that the The preset surface of the electronic device faces the preset collision object, so as to prevent the fragile parts of the electronic device from contacting the preset collision object first. Thus, the probability of breaking the screen of the electronic device is reduced.

Referring to FIG. 5, it is a schematic diagram of the centrifugal force generated by the rotation of the rotating block 30. In this embodiment, when the rotating block 30 rotates to 270-360 degrees, a part of the rotating block 30 is located outside the opening 22, and the rotating block 30 rotates to generate centrifugal force . Between 0 and 270 degrees, the entire rotating block 30 is located in the accommodating cavity, and the center of gravity of the rotating block 30 coincides with the axis line of the fixed sleeve 20, so the rotating block 30 does not generate centrifugal force during this period. That is to say, one pulse of centrifugal force is generated every one rotation of the rotating block 30 . In the process of adjusting the angle of the electronic device, at least one pulse of centrifugal force, or a plurality of pulses of centrifugal force is required.

In one implementation, specifically, the limiting member 10 includes two arcuate claws 122 disposed opposite to each other, the two arcuate claws 122 constitute the outlet 12 , and the part of the rotating block 30 located outside the opening 22 is also located at the outlet 12 . That is to say, the opening 22 and the outlet 12 communicate with each other, and the part of the rotating block 30 located outside the opening 22 is surrounded by the two arc claws 122 . The portion of the rotating block 30 located in the opening 22 abuts against the arc claw 122 during the rotation process, and the arc claw 122 squeezes the rotating block 30 so that the rotating block 30 compresses the elastic member 40 . Further, in one embodiment, the diameter of the outlet 12 is larger than the width of the portion of the rotating block 30 outside the opening 22 , so that the rotating block 30 rotates relative to the limiting member 10 by a predetermined angle and then interferes with the arc claw 122 . In a period corresponding to one rotation of the rotating block 30, the rotating block 30 stays outside the opening 22 for a longer time, that is, the rotating block 30 generates centrifugal force for a longer time.

In other embodiments, the diameter of the outlet 12 may be only slightly larger than the width of the portion of the rotating block 30 located outside the opening 22, so that the portion of the rotating block 30 outside the opening 22 immediately contacts the arc claw 122 when the rotating block 30 starts to rotate. . It can be understood that when the diameter of the outlet 12 is smaller, the direction of the centrifugal force generated by the rotating block 30 during the rotation of the rotating block 30 is more consistent. In different embodiments, the diameter of the outlet 12 may be specifically limited according to actual needs.

Further, in one embodiment, one end or both ends of the limiting member 10 is provided with a limiting sleeve 14, and the limiting sleeve 14 is provided with a groove (not shown) that communicates with the outlet 12 of the limiting member 10, and the fixing sleeve 20 It is accommodated in the groove and outlet 12 which communicate with each other. Adopting such a structure can prevent the fixing sleeve 20 from axially slipping from the limiting member 10 and being separated from the limiting member 10. In this embodiment, the outlet 12 of the limiting member 10 axially penetrates, or at least one end penetrates through to connect the fixing sleeve 20 is placed in.

Further, in one embodiment, the rotating block 30 includes a base body 32 and an extension portion 34 extending from the base body 32 along the axis of the fixing sleeve 20 . The extension portion 34 is used to prevent the whole or most of the rotating block 30 from popping out from the opening 22 of the fixing sleeve 20 and being difficult to retract. In other embodiments, the rotating block 30 can also be in other shapes, such as a long strip, and the size of the elastic force that can be generated by the elastic element 40 is controlled by controlling the amount of compression of the elastic element 40, and then only the base body 32 of the rotating block 30 can be controlled. The opening 22 of the fixing sleeve 20 is ejected.

In one embodiment, the centrifugal motor 100 of the present application further includes a handle 16 integrally formed with the limiting member 10 , as shown in FIG. 3 , a through hole is formed on the handle 16 . The handle 16 is provided mainly to facilitate the installation of the centrifugal motor 100 to other devices. In other embodiments, the above-mentioned handle 16 may not be included, for example, an accommodating hole is opened on the device to be installed, and the installation can be performed by interference fit or fixed connection by an adhesive layer.

Referring to FIG. 6 , the present application further provides an electronic device 200 having the centrifugal motor 100 described in any of the above embodiments. Specifically, the electronic device 200 in the present application may be a mobile phone, an IPad, a smart wearable device, a digital audio and video player, an electronic reader, a handheld game console, a vehicle-mounted electronic device, a digital camera, a flash disk, and the like.

Referring to FIG. 7, optionally, in an embodiment, the centrifugal motor 100 installed in the electronic device 200 includes a first centrifugal motor 100a and a second centrifugal motor 100b, and the first and second centrifugal motors 100a and 100b are respectively fixed to the electronic device On opposite sides of the device 200 in the length direction, the centrifugal force generated by the rotating blocks 30 of the first and second centrifugal motors 100a and 100b has at least components in opposite directions. The different cases are as follows:

For example, the direction of the centrifugal force generated by the first centrifugal motor 100a acting on the electronic device 200 is opposite to the direction of the centrifugal force generated by the second centrifugal motor 100b acting on the electronic device 200 . For example, one centrifugal force is perpendicular to the display screen of the electronic device 200 upward, and the other centrifugal force is perpendicular to the display screen of the electronic device 200 downward, which is equivalent to one centrifugal force pulling upward, and the other centrifugal force pulling downward. The directions of the two centrifugal forces are opposite, so that the electronic device 200 can adjust the angle faster, for example, the electronic device 200 can be adjusted to a downward angle of the display screen to an upward angle of the display screen to avoid the collision of the display screen when the electronic device 200 hits the ground. On the ground, reduce the chance of the display breaking.

Optionally, in another embodiment, the first and second centrifugal motors 100a and 100b are respectively fixed on opposite sides of the electronic device 200 in the width direction, as shown in FIG. 8 .

In other embodiments, the directions of the centrifugal forces generated by the first and second centrifugal motors 100a and 100b may not be completely opposite, as long as the respective component forces of the two centrifugal forces are opposite in the same direction.

9, in another embodiment, at least two centrifugal motors 100c are installed on an electronic device 200a, the two centrifugal motors 100c are arranged side by side, and the centrifugal forces generated by the rotating blocks of the two centrifugal motors 100c are in the same direction. In another embodiment, the components of the centrifugal forces generated by the centrifugal forces generated by the rotating blocks 30 of the two centrifugal motors 100c may be the same in one direction. With such a structure, the two parallel centrifugal motors 100c can generate a larger or more continuous centrifugal force acting on the electronic device 100a, that is, two centrifugal forces can be generated in one cycle. Specifically, the centrifugal force of the two pulses generated by the two centrifugal motors 100c can be in the same time period or in different time periods, so that the angle of the electronic device 100a can be adjusted more quickly.

It can be understood that, in other embodiments, the number of centrifugal motors 100c arranged side by side may also be three or more, which is not specifically limited.

Referring to FIG. 10, further, in yet another embodiment, at least two centrifugal motors 100d are arranged side by side on opposite sides of the electronic device 200b in the length direction, or on opposite sides in the width direction of the electronic device 200b, respectively, and the side-by-side on the same side The centrifugal force generated by the centrifugal motors 100d has at least a component force in the same direction, while the centrifugal force generated by the side-by-side centrifugal motors 100e on the other side is in the opposite direction to the centrifugal force generated by the side-by-side centrifugal motors 100d on one side. For example, the centrifugal force generated by the at least two centrifugal motors 100d arranged side by side near the top camera of the electronic device 200b is vertical to the display screen, while the centrifugal force generated by the at least two centrifugal motors 100d arranged side by side on the side near the bottom button of the electronic device 200d The centrifugal force is perpendicular to the display screen downward, and the forces in the two directions act together on the electronic device, and the adjustment speed is faster. It can be understood that the directions of the centrifugal forces generated by the at least two centrifugal motors 100d disposed side by side near the top camera of the electronic device 200b may not be exactly the same, as long as each centrifugal force has a component force in the same direction. The centrifugal forces generated by the at least two centrifugal motors that are arranged side by side near the button side of the bottom of the electronic device 100b may not be exactly the same, which will not be repeated here.

It can be understood that, in an embodiment, the centrifugal force component of the centrifugal force generated by the side-by-side centrifugal motors 100e on the other side of the electronic device 200b is in the opposite direction to the centrifugal force generated by the side-by-side centrifugal motors 100d on the side of the electronic device 200b. Can.

Optionally, in different embodiments, three centrifugal motors may also be provided on one electronic device 200c. For example, in one embodiment, one centrifugal motor 100f is located at the top of the electronic device 200c, and the other two centrifugal motors 100f are arranged side by side at the bottom of the electronic device 200c, as shown in FIG. 11 . In another embodiment, the first centrifugal motor 100g is located at the top of the electronic device 200d, the second centrifugal motor 100g is located at the bottom of the electronic device 200c, and the third centrifugal motor 100g is located at the middle edge of the electronic device 200c, as shown in FIG. 12 . shown. In other embodiments, the positions of the three centrifugal motors 100 on the electronic device 200 can be adjusted according to actual needs. Specifically, the direction of the centrifugal force generated by the three centrifugal motors 100 is the same as the setting principle of the above embodiment, mainly because the multiple centrifugal forces act together on the electronic device 200 to speed up the adjustment of the electronic device 200 , which is not repeated here. Of course, in other embodiments, a larger number of centrifugal motors 100 may be provided as required.

The present application also provides a method for adjusting the angle of an electronic device during a falling process of the electronic device, which is applied to the electronic device described in any of the above embodiments. FIG. 13 is a schematic flowchart of an embodiment of the method in the present application. Methods include:

101: Determine whether the electronic device is in a falling process.

In one embodiment, an acceleration sensor is set in the electronic device, and if the acceleration sensor detects the generation of gravitational acceleration, that is, the electronic device is in a free fall state, it is determined that the electronic device is in a falling state. Specifically, in different embodiments, it can be determined by the change of the acceleration in the direction of gravity of the electronic device and the time when the acceleration is generated. This is not elaborated.

102 : If the electronic device is in the process of falling, start the centrifugal motor so that the rotating block of the centrifugal motor generates centrifugal force to adjust the angle of the electronic device so that the preset surface of the electronic device faces the preset collision object.

When the centrifugal motor is started, the rotating block rotates and periodically eccentrically eccentric with the axis of the fixed sleeve to generate centrifugal force. The generated centrifugal force acts on the electronic device, so that the preset surface of the electronic device faces the preset collision object. Specifically, the preset surface of the electronic device is a surface that is relatively unbreakable or relatively impact-resistant, such as the back of the electronic device, or the surface with a protective cover. In different embodiments, the user can set a surface by himself according to the actual structure of the electronic device, or a part is a preset surface. The collision object generally refers to the ground, and may also be a wall or a tree trunk in other embodiments, for example, when the user falls and the electronic device is thrown out by force.

FIG. 14 is a schematic flowchart of the steps of the method in another embodiment. The method includes steps 201 to 204, wherein steps 201 and 202 are consistent with the above-mentioned embodiments, which will not be repeated here. The following focuses on steps 203 and 204:

201: Determine whether the electronic device is in a falling process.

202 : If the electronic device is in the process of falling, start the centrifugal motor, so that the rotating block of the centrifugal motor generates centrifugal force, so as to adjust the angle of the electronic device, so that the preset surface of the electronic device faces the preset collision object.

203 : Determine whether the electronic device is adjusted so that the preset surface faces the preset collision object.

The distance change between the preset surface and the preset collision object, and the distance change between the side opposite to the preset surface and the preset collision object are detected by the distance sensor, if the distance between the preset surface and the preset collision object changes The change and the change trend of the distance between the side opposite to the preset surface and the preset collision object are the same, for example, they are getting smaller and smaller, and the distance ratio between the preset surface and the preset collision object is the same as the preset surface. If the distance between the back side and the preset collision object is smaller, it is determined that the electronic device has been adjusted so that the preset surface faces the preset collision object. In other embodiments, the variation of the distance and the light conditions of the predetermined surface and the surface position of the surface opposite to the predetermined surface may also be used. For example, if the distance between the preset surface and the preset collision object changes and the distance between the side opposite to the preset surface and the preset collision object changes in the same trend, for example, they are getting smaller and smaller, and the preset surface If the light on the surface is opposite to the light on the surface of the surface opposite to the preset surface, it is determined that the electronic device has been adjusted so that the preset surface faces the preset collision object.

204: If yes, turn off the centrifugal motor.

Since the electronic device has been adjusted so that the preset surface faces the preset collision object, it is only necessary to turn off the centrifugal motor at this time, so that the preset surface of the electronic device can touch the collision object instead of the fragile surface of the electronic device. Protect electronic devices well.

Specifically, the above-mentioned device with a storage function may be one of a personal computer, a server, a network device, or a USB flash drive.
