It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

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 casing 10, a rotating shaft 20 rotatably connected to the casing 10, a fixed sleeve 22 disposed on the rotating shaft 20, at least two rotating blocks 30 accommodated in the fixed sleeve 22, disposed in the fixed sleeve or At least one group of magnetic coils on the housing and a drive mechanism 50 rotatably connected with the rotating shaft 20 .

Specifically, in an embodiment, the rotating shaft 20 is rotatably connected to the housing 10 , the rotating shaft 20 is provided with a fixing sleeve 22 , and the fixing sleeve 22 forms an accommodating cavity, and at least two fixing sleeves 22 are opened to communicate with the accommodating cavities. opening 224. In one embodiment, a support member 142 is disposed on the housing 10 , and a part of the support member 142 is located opposite to the outlet 124 of the limiting member 12 , and the support member 142 is used for fixing the magnetic coil 70 . A schematic view of the sleeve 14 extending out of the support 142 is given in FIG. 5 . In other embodiments, the magnetic coil 70 may also be fixed at a position at the bottom of the fixing sleeve 22 opposite to the opening 224 . At least two rotating blocks 30 are accommodated in the fixing sleeve 22 , at least two rotating blocks 30 are magnetic bodies, and correspond to the two openings 224 one-to-one. The driving mechanism 50 is connected with the rotating shaft 20 to rotate the rotating shaft 20 and drive the fixed sleeve 22 and the rotating block 30 to rotate relative to the casing 10 .

At the same time, in conjunction with FIG. 4 , the following takes the case where there are two rotating blocks 30 and the magnetic coil 70 is fixed at the bottom of the fixed sleeve 22 as an example to explain the process of cooperation between the various components during the rotation of the rotating shaft 20 for one circle: the role of the driving mechanism 50 Then, the rotating shaft 20 rotates relative to the casing 10. Since the two rotating blocks 30 are magnetic bodies, the magnetic coil 70 generates periodic repulsive force and attractive force acting on the two rotating blocks 30, so that the two rotating blocks 30 periodically or sequentially The sex part is located outside the opening 224 , so that the center of gravity of the rotating block 30 deviates from the axis line of the rotating shaft 20 periodically. When the magnetic coil 70 generates a repulsive force on the rotating block 30, the rotating block 30 is repelled by the repulsive force and has a part located outside the opening 224 of the fixed sleeve 22, and the center of gravity of the rotating block 30 deviates from the axis line of the rotating shaft 20; on the contrary, in the magnetic coil 70 When an attractive force is generated on the rotating block 30 , the rotating block 30 is pulled back into the fixed sleeve 22 by the attractive force. At this time, the center of gravity of the rotating block 30 coincides with the axis line of the rotating shaft 20 .

During the rotation of the rotating shaft 20 , when a part of the rotating block 30 is located outside the opening 224 , centrifugal force will be generated because the center of gravity of the rotating block 30 deviates from the axis line of the rotating shaft 20 . When the electronic device falls, the rotating shaft 20 can be rotated, and the angle of the electronic device can be adjusted by the centrifugal force generated by the centrifugal motor 100, so that the predetermined surface of the electronic device faces the predetermined collision object, so as to prevent the fragile parts of the electronic device from first Touch the preset collider. Thus, the probability of breaking the screen of the electronic device is reduced.

In contrast, in the embodiment in which the magnetic coil 70 is located on the support 142 of the housing 10, referring to FIG. 5, the rotating block 30 is partially protruded from the opening 224 of the fixed sleeve 22 by the attractive force of the magnetic coil 70, and after a short period of time Retracted into the fixed sleeve 22 by the push force of the magnetic coil 70, and the cycle repeats. The specific principle and process are similar to the case where the magnetic coil 70 is fixed in the fixing sleeve 22 , and details are not described here.

Assuming that the time for one rotation of the rotating shaft 20 is one cycle, a part of the rotating block 30 is located outside the opening 224 during a part of one cycle during the one rotation of the rotating shaft 20 . When the rotating block 30 is partially located outside the opening 224 of the fixed sleeve 22, the center of gravity of the rotating block 30 does not coincide with the axis of the rotating shaft 20. At this time, with the rotation of the rotating shaft 20, the rotating block 30 will generate a centrifugal force.

Referring to FIG. 6 , it is a schematic diagram of a rotating block 30 generating centrifugal force when the rotating shaft 20 rotates for one week. In this embodiment, when the rotating shaft rotates to 270-360 degrees, a rotating block 30 has a part located outside the opening 224, and the rotating block 30 Rotation generates 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 of the rotating shaft 20, so the rotating block 30 does not generate centrifugal force during this period. That is to say, every time the rotating shaft 20 rotates once, the rotating block 30 generates a pulse of centrifugal force. In the process of adjusting the angle of the electronic device, at least one pulse of centrifugal force, or multiple pulses of centrifugal force is required.

During one rotation of the rotating shaft 20 , the two rotating blocks 30 will generate two centrifugal forces, wherein the two centrifugal forces can be generated simultaneously in different embodiments or separately generated in sequence, that is, the center line connecting the two openings 224 and the rotating shaft The axis lines of the openings 20 are parallel, or the two openings 224 are out of phase by a preset phase. For example, in one embodiment, the preset phases of the two openings 224 on the fixing sleeve 22 are both 90°. If a rotating block 30 is partially located outside the opening 224, the rotating shaft rotates 1/4 turn, and the two rotating blocks If the preset phase of the opening 224 corresponding to 30 is 90°, the centrifugal force is generated during half of the rotation of the rotating shaft 20, as shown in FIG. 7 . Further, in other embodiments, the number of rotating blocks 30 can be increased according to actual needs to generate greater centrifugal force; or by setting more rotating blocks 30, centrifugal force is always generated during the rotation of the rotating shaft 20, or there is a higher centrifugal force. Centrifugal force is generated over time.

In other embodiments, the preset phase of the two adjacent openings 224 may be any value between 0 and 90°. When the preset phase difference between the two openings 224 is 0 degrees, the two openings 224 are arranged side by side. As shown in Figure 3. In this embodiment, the centrifugal force generated by the two rotating blocks 30 during one rotation of the rotating shaft 20 is twice that of the centrifugal force generated by a single rotating block 30 .

The structure of at least two rotating blocks 30 can greatly increase the magnitude of the centrifugal force generated by the centrifugal motor, and the fixed sleeve 22 can also be provided with openings 224 that are different from the preset phases, so that the rotating shaft 20 can be completely or completely closed during the rotation process. Centrifugal force is generated part of the time, which in turn can adjust the angle of the electronic device more quickly.

In one embodiment, when the two openings 224 of the fixed sleeve 22 are not in the same phase, the magnetic coils 70 include two groups, and each group of the magnetic coils 70 corresponds to one rotating block 30 so that a part of one rotating block 30 enters and exits the opening 224 The force generated by the corresponding set of magnetic coils 70 is controlled.

Referring to FIGS. 3 and 8 , in one implementation, the centrifugal motor 100 further includes a limiting member 12 . Specifically, the limiting member 12 includes two arcuate claws 122 disposed opposite to each other. The two arcuate claws 122 constitute the outlet 124 , and the portion of the rotating block 30 located outside the opening 224 is also located at the outlet 124 . That is to say, the opening 224 and the outlet 124 communicate with each other. In one embodiment, the housing 10 further includes a sleeve 14 , the sleeve 14 is fixedly connected with the limiting member 12 , and the rotating shaft 20 is partially located in the sleeve 14 . Specifically, the shape of the sleeve 14 may be a cylindrical shape, a rectangular parallelepiped, or other shapes, as long as it has a cavity for a part of the rotating shaft 20 to pass through. A part of the rotating shaft 20 is passed through the sleeve 14 , and at the same time, the fixing sleeve 22 on the rotating shaft 20 is located in the outlet 124 of the limiting member 12 .

Further, in another embodiment, a gap 16 is formed between the sleeve 14 and the limiting member 12 , the fixing sleeve 22 is provided with first fixing rings 24 on both sides of the shaft 20 in the axial direction, and the first fixing rings 24 are located in the gap 16 Inside, the first fixing ring 24 is sandwiched between the end face of the sleeve 14 and the fixing sleeve 22 . With such a structure, the first fixing ring 24 can prevent the rotating shaft 20 from being separated from the housing 10 by force in the longitudinal direction of the rotating shaft 20 , and at the same time, the part of the rotating shaft 20 located in the sleeve 14 can prevent the rotating shaft 20 from being perpendicular to the length of the rotating shaft 20 . The directional force is separated from the housing 10 . It can be understood that under the combined action of the first fixing ring 24 and the part of the rotating shaft 20 located in the sleeve 14 , it is ensured that the entire rotating shaft 20 will not be separated from the casing 10 under any force in any direction, and the structure is very stable.

Further, in another embodiment, the fixing sleeve 22 is provided with a first fixing ring 24 and a second fixing ring 26 on both sides of the axis of the rotating shaft 20, the first fixing ring 24 is located in the gap 16, and the arc claw 12 is located in the between the first and second fixing rings 24 and 26 . With such a structure, the rotation shaft 20 can be combined with the housing 10 more firmly.

Specifically, in different embodiments, the housing 10 and the limiting member 12 may be integrally formed or detachably connected, such as glued or screwed. It can be understood that the part of the rotating shaft 20 located in the sleeve 14 and the first fixing ring 24 may be integrally formed or detachably connected, such as glued or threaded connection. This connection method is used to facilitate the smooth installation of the rotating shaft 20 on the housing 10 . Taking the threaded connection between the part of the rotating shaft 20 located in the casing 14 and the first fixing ring 24 as an example, when installing, the first fixing ring 24 can be placed at the gap 16 first, and at the same time, the fixing ring 24 with the rotating block 30 can be fixed. The sleeve 22 is located in the outlet 124 , and finally, the part of the rotating shaft 20 located in the sleeve 14 is threadedly connected to the first fixing ring 24 through the sleeve 14 to be fixed. In other embodiments, other connection manners may also be used, and details are not described herein.

To sum up, the limiting member 12 plays the role of fixing and limiting the rotating shaft 20 and the fixing sleeve 22. In addition, when the outlet 124 of the limiting member 12 is slightly larger than the width of the portion of the rotating block 30 located outside the opening 224, the limiting member 12 also The function of assisting the rotating block 30 to enter the fixed sleeve 22 is as follows.

The portion of the rotating block 30 located outside the opening 224 is surrounded by two arcuate claws 122. When the opening of the stopper 12 is slightly larger than the width of the rotating block 30 outside the opening 224, due to inertia, it may occur that the rotating block 30 is subjected to magnetic lines of force. When the repulsive force or the pulling force of the ring does not move into the fixed sleeve 22 . Then, the part of the rotating block 30 at the opening 224 abuts against the arc claw 122 during the rotation of the rotating shaft 20 .

In one embodiment, the first fixing ring 24 and the second fixing ring 26 are annular, and a through groove 262 is formed in the middle for accommodating the rotating block 30 .

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 rotating shaft 20 . Specifically, the base body 32 is disposed facing the opening 224 of the fixing sleeve 22 , and the width of the base body 32 is smaller than the width of the opening 224 so as to be able to enter and exit the opening 224 . Optionally, in one embodiment, the width of the extension portion 34 is greater than the width of the opening 224 to prevent the entire rotating block 30 from protruding from the fixed sleeve 22 , or the majority of the volume of the rotating block 30 protruding from the fixed sleeve 22 and difficult to return to the fixed sleeve 22 . In other embodiments, the rotating block 30 can also be in other shapes, such as a long bar or a cylinder, and the length of the rotating block 30 that can protrude from the opening is controlled by setting the magnitude of the force generated by the magnetic coil.

In one embodiment, the housing 10 of the present application further includes a handle 18 integrally formed with the sleeve 14 and the limiting member 12 , as shown in FIG. 3 , a through hole is formed on the handle 18 . The handle 18 is provided mainly to facilitate the installation of the centrifugal motor 100 to other devices. In other embodiments, the above-mentioned handle 18 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.

In this embodiment, the driving mechanism 50 is a magnetic coil, and the rotating shaft 20 is partially sleeved in the magnetic coil. That is to say, when the rotating block 30 needs to generate centrifugal force, the magnetic coil is energized, and after the magnetic coil is energized, a magnetic force acts on the rotating shaft 20 to make the rotating shaft 20 rotate, thereby driving the rotating block 30 to rotate. It can be understood that the part of the rotating shaft 20 located in the sleeve 14 contains a permanent magnet rotor.

Optionally, in other embodiments, the driving mechanism 50 may also be other types of other motors capable of generating power, such as motors.

Referring to FIG. 9 , 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. 10, 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. 11 .

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.

Referring to FIG. 12 , 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 larger or more continuous centrifugal force acting on the electronic device 100a, that is, two centrifugal forces can be generated when the rotating shaft 20 rotates once. 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. 13, 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. 14 . 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. 15 . 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. 16 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 starts, the rotating shaft rotates, which drives the rotating block to rotate eccentrically, thereby generating centrifugal force, which 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. 17 is a schematic flow chart 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 embodiment, which will not be repeated, and 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.
