The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
Referring to fig. 1-3, the present application provides a centrifugal motor 100, wherein the centrifugal motor 100 is capable of generating a centrifugal force, thereby allowing a device in which the centrifugal motor 100 is installed to be angled by the centrifugal force. The centrifugal motor 100 includes a housing 10, a shaft 20 rotatably connected to the housing 10, a fixing sleeve 22 disposed on the shaft 20, a rotating block 30 partially received in the fixing sleeve 22, an elastic member 40 disposed between the fixing sleeve 22 and the rotating block 30, and a driving mechanism 50 rotatably connected to the shaft 20.
Specifically, in an embodiment, the limiting member 12 is disposed on the housing 10, the limiting member 12 is disposed with an outlet 124, the rotating shaft 20 is rotatably connected to the housing 10, the rotating shaft 20 is disposed with a fixing sleeve 22, the fixing sleeve 22 forms an accommodating cavity 224, and the fixing sleeve 22 is disposed with four openings 224 mutually communicating with the accommodating cavity 224, wherein each two adjacent openings 224 differ by a predetermined phase. The four rotating blocks 30 are magnetic bodies and are all accommodated in the fixed sleeve 22, and the four rotating blocks 30 correspond to the four openings 224 one by one respectively. The elastic element 40 is disposed between the inner wall of the housing cavity surrounded by the fixed sleeve 22 and the rotating block 30, and the driving mechanism 50 is connected to the rotating shaft 20, so as to rotate the rotating shaft 20 and drive the fixed sleeve 22 and the rotating block 30 to rotate relative to the housing 10.
The following explains the matching process between the components during one rotation of the rotating shaft 20, with reference to fig. 4: under the action of the driving mechanism 50, the rotating shaft 20 rotates relative to the housing 10, so that each opening 224 on the fixed sleeve 22 is simultaneously or sequentially opposite to the outlet 124 on the limiting member 12, when the rotating block 30 is wholly located in the fixed sleeve 22, each spring 40 is compressed and stored by the corresponding rotating block 30, so that when the corresponding openings of the four rotating blocks 30 are opposite to the openings on the limiting members, the elastic member 40 extends to push the rotating blocks 30, so that the four rotating blocks 30 are simultaneously or sequentially partially located outside the openings 224. As the rotating shaft 20 continues to rotate, the four rotating blocks 30 simultaneously or sequentially abut against the limiting members 12, so that the limiting members 12 extrude the rotating blocks 30, and further the rotating blocks 30 compress the elastic members 40 and move toward the accommodating cavities of the fixed sleeve 22, so that the center of gravity of the rotating blocks 30 coincides with the axis of the rotating shaft 20 simultaneously or sequentially. As the rotating shaft 20 continues to rotate, the opening 224 of the fixing sleeve 22 is simultaneously or sequentially opposite to the outlet 124 of the limiting member 12, and the compressed elastic member 40 releases energy and simultaneously or sequentially pushes a portion of the rotating block 30 to protrude out of the opening 224, and so on.
When the rotating block 30 is partially located outside the opening 224 of the fixing sleeve 22, the center of gravity of the rotating block 30 deviates from the axial line of the rotating shaft 20, so that a pulse centrifugal force is generated, therefore, when the electronic device of the centrifugal motor 100 is applied, the rotating shaft 20 can be rotated in the process of detecting that the electronic device falls, the angle of the electronic device is adjusted by using the pulse centrifugal force generated by the centrifugal motor 100, so that the preset surface of the electronic device faces to the preset collision object, and the fragile part of the electronic device is prevented from contacting the preset collision object first. Thereby reducing the probability of breaking the screen of the electronic device.
Assuming that the time of one rotation of the rotating shaft 20 is one period, during the one rotation of the rotating shaft 20, any one of the four rotating blocks 30 is partially located outside the opening 224 during a part of 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, and a centrifugal force is generated by the rotating block 30 along with the rotation of the rotating shaft 20.
It can be understood that during the pressing process when the rotating block 30 abuts against the limiting member 12, the rotating block gradually retracts into the receiving cavity of the fixing sleeve 22, so that during the pressing process, the volume of the rotating block 30 outside the opening 224 gradually changes. Referring to fig. 5, a schematic diagram of an embodiment in which the rotating shaft 20 rotates once and one of the rotating blocks 30 generates a centrifugal force is shown, in the embodiment, when the rotating shaft 20 rotates to 270 degrees to 360 degrees, a portion of the rotating block 30 is located outside the opening 224, and the rotating block 30 rotates to generate the centrifugal force. And between 0 and 270 degrees, the rotating block 30 is entirely positioned in the accommodating cavity, and the center of gravity of the rotating block 30 is superposed with the axis of the rotating shaft 20, so that the rotating block 30 does not generate centrifugal force during the period. That is, one rotating block 30 generates one pulse of centrifugal force per one rotation of the rotating shaft 20. The electronic device requires at least one pulse of force, or a plurality of pulses of force, during the angular adjustment process.
During one rotation of the shaft 20, four centrifugal forces are generated by the four rotating blocks 30, wherein the four centrifugal forces may be generated simultaneously in different embodiments or may be generated sequentially separated from each other, or two or three centrifugal forces may be generated simultaneously. For example, in one embodiment, the predetermined phase of every two adjacent openings 224 on the fixing sleeve 22 is 90 °, if the time when one of the rotation blocks 30 is partially located outside the openings 224 is 1/4 rotations of the rotation shaft, and the predetermined phase of the openings 224 corresponding to four rotation blocks 30 is 90 °, a centrifugal force is generated during one rotation of the rotation shaft 20, as shown in fig. 6.
In other embodiments, the predetermined phase of each adjacent two openings 224 may be any value from 0 to 90 °, and when the predetermined phase of the difference between the four openings 224 is 0 degrees, the four openings 224 are arranged side by side, as shown in fig. 3. In this embodiment, the centrifugal force generated by four rotating blocks 30 during one rotation of the rotating shaft 20 is four times the centrifugal force generated by a single rotating block 30.
By adopting the structure of four rotating blocks 30, the centrifugal force generated by the centrifugal motor can be greatly increased, and the opening 224 with a preset phase difference can be formed in the fixed sleeve 22, so that the rotating shaft 20 generates the centrifugal force in the whole or most time in the rotating process, and the angle of the electronic device can be adjusted more quickly.
In one embodiment, the position-limiting member 12 includes two circular arc claws 122 oppositely disposed, the two circular arc claws 122 form an outlet 124, and the portion of the rotating block 30 outside the opening 224 is located at the outlet 124. Specifically, in various embodiments, the outlet 124 may be an elongated slot, or may be four outlets 124 respectively disposed at corresponding positions of the four openings 224 on the fixing sleeve 22. That is, the opening 224 and the outlet 124 communicate with each other, and the portion of the rotating block 30 located outside the opening 224 is surrounded by the two arc claws 122. The portion of the rotating block 30 located in the opening 224 contacts the arc claw 122 during the rotation, and the arc claw 122 presses the rotating block 30, so that the rotating block 30 compresses the elastic member 40. Further, in an embodiment, the diameter of the outlet 124 is larger than the width of the portion of the rotating block 30 outside the opening 224, so that the rotating block 30 rotates a predetermined angle relative to the housing 10 and then interferes with the circular arc claw 122. So that the rotating block 30 has a longer time to stay outside the opening 224 in a period corresponding to one rotation of the rotating shaft 20, i.e. the time for generating centrifugal force by the rotating block 30 is also longer.
In other embodiments, the diameter of the outlet 124 may be only slightly larger than the width of the portion of the rotating block 30 outside the opening 224, so that the portion of the rotating block 30 outside the opening 224 immediately contacts the circular arc claw 122 when the rotating shaft 20 starts to rotate. It can be understood that the smaller the diameter of the outlet 124, the more uniform the centrifugal force generated by the rotating block 30 during the rotation of the rotating shaft 20. In various embodiments, the size of the aperture of the outlet 124 may be specifically limited according to actual requirements.
Referring to fig. 3 and fig. 6, in particular, in an embodiment, the housing 10 further includes a sleeve 14, the sleeve 14 is fixedly connected to the limiting member 12, and the rotating shaft 20 is partially located in the sleeve 14. The shape of the sleeve 14 may be cylindrical or rectangular, or other shapes, as long as it has a cavity for a portion of the shaft 20 to pass through. A portion of the shaft 20 is inserted into the sleeve 14, and the fixing sleeve 22 on the shaft 20 is located in the outlet 124 of the position-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 two sides of the rotating shaft 20 in the axial direction, and the first fixing rings 24 are located in the gap 16, so that the first fixing rings 24 are clamped between the end surface of the sleeve 14 and the fixing sleeve 22. With such a structure, the rotation shaft 20 can be prevented from being forced to be separated from the housing 10 in the length direction of the rotation shaft 20 by the first fixing ring 24, while the rotation shaft 20 is prevented from being forced to be separated from the housing 10 in the direction perpendicular to the length direction of the rotation shaft 20 by the portion of the rotation shaft 20 located in the sleeve 14. It can be understood that the cooperation of the first fixing ring 24 and the portion of the rotating shaft 20 located in the sleeve 14 ensures that the entire rotating shaft 20 is not separated from the housing 10 by any force in any direction, and the structure is very stable.
Furthermore, in another embodiment, the fixing sleeve 22 is provided with a first fixing ring 24 and a second fixing ring 26 at two sides of the axial direction of the rotating shaft 20, the first fixing ring 24 is located in the notch 16, and the arc claw 12 is located between the first and second fixing rings 24, 26. Adopting such a structure enables the shaft 20 to be more firmly coupled with the housing 10.
Specifically, in various embodiments, the housing 10 and the limiting member 12 may be integrally formed or detachably connected, such as glued or screwed. It will be appreciated that the portion of the shaft 20 within the sleeve 14 and the first retaining ring 24 may be integrally formed or may be removably attached, such as by gluing or threading. Such a connection is adopted to facilitate smooth mounting of the rotary shaft 20 on the housing 10. Taking the threaded connection between the portion of the rotating shaft 20 located in the sleeve 14 and the first fixing ring 24 as an example, the first fixing ring 24 may be first placed at the notch 16 while the fixing sleeve 22 with the rotating block 30 is located in the outlet 124, and finally the portion of the rotating shaft 20 located in the sleeve 14 is threaded through the sleeve 14 and fixed to the first fixing ring 24. In other embodiments, other connection manners may be adopted, which is not described herein.
In one embodiment, the first retaining ring 24 and the second retaining ring 26 are annular and have a through slot 262 therebetween for connecting the rotating block 30.
In one embodiment, the housing 10 of the present application further includes a handle 18 integrally formed with the sleeve 14 and the stopper 12, as shown in fig. 3, the handle 18 is provided with a through hole. The handle 18 is provided primarily to facilitate mounting of the centrifuge motor 100 to other devices. In other embodiments, the handle 18 may not be included, such as by forming a receiving hole in the device to be mounted, by interference fit, or by fixedly attaching with an adhesive layer.
In one embodiment, the rotating block 30 includes a base 32 and an extending portion 34 extending from the base 32 along the axial direction of the rotating shaft 20. In particular, the base 32 is disposed facing the opening 224 of the pouch 22, and the width of the base 32 is less than the width of the opening 224 to enable access to the opening 224. Optionally, the width of the extension 34 in one embodiment is greater than the width of the outlet 124 to avoid the entire rotating block 30 from extending out of the holster 22, or the majority of the volume of the rotating block 30 extending out of the holster 22 is difficult to return to the holster 22. In other embodiments, the rotation block 30 may have other shapes, such as an elongated shape and a cylindrical shape, and the length of the rotation block 30 that can extend out of the opening portion is controlled by setting the compression amount of the elastic member 40.
In this embodiment, the elastic members 40 are respectively fixed to the bottom of the fixing sleeve 22, i.e. located right below the base 32, as shown in fig. 7. In another embodiment, the elastic member 40 can be fixed to the bottom of the rotation block 30, as long as the elastic member 40 can be extended and contracted in cooperation with the bottom of the fixing sleeve 22.
In another embodiment, with reference to fig. 8, the centrifugal motor 100 further includes a fastening member 60, and the extension portion 34 is respectively provided with a fastening hole 342, the elastic member 40 is located in the through groove 262 of the first fixing ring 24 and the second fixing ring 26 and the accommodating cavity of the fixing ring 22 and respectively and correspondingly disposed right below the extension portion 34, and the fastening member 60 sequentially passes through the side wall of the first fixing ring 24 or the second fixing ring 26 and the elastic member 40 and is fastened in the fastening hole 342 of the extension portion 34. The elastic element 40 located in the housing cavity of the fixing sleeve 22 is arranged in the following way: the fastening member 60 is sequentially inserted through the outer wall of the fixing sleeve 22 and the elastic member 40 and locked in the fastening hole 342 of the extension body 34, and optionally, the fastening member 60 may be fixed on the outer wall of the fixing sleeve 22 through the extension body 34. With the above structure, the assembly among the fastening member 60, the rotating block 30, the first fixing ring 24 and/or the second fixing ring 26, and the elastic member 40 is compact. It is understood that the elastic member 40 in this embodiment is a spring, and in other embodiments, the elastic member 40 may be other elastic members such as an elastic column.
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 is required to generate centrifugal force, the magnetic coil is powered on, and after the magnetic coil is powered on, magnetic force is generated to act on the rotating shaft 20, so that the rotating shaft 20 rotates, and the rotating block 30 is further driven to rotate. It will be appreciated that the portion of the shaft 20 located within the sleeve 14 contains a permanent magnet rotor.
Alternatively, in other embodiments, the drive mechanism 50 may be another type of motor capable of generating power, such as a servo motor.
Referring to fig. 9, the present application further provides an electronic device 200, wherein the electronic device 200 has the centrifugal motor 100 as described in any of the above embodiments. Specifically, the electronic device 200 in the present application may be a mobile phone, an IPad, an intelligent wearable device, a digital audio/video player, an electronic reader, a handheld game console, a vehicle-mounted electronic device, a digital camera, a flash drive, 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 on two opposite sides of the electronic device 200 in the length direction, and the centrifugal forces generated by the rotating blocks 30 of the first and second centrifugal motors 100a and 100b have at least components with opposite directions. The different cases are as follows:
for example, the centrifugal force generated by the first centrifugal motor 100a acting on the electronic device 200 is opposite to the centrifugal force generated by the second centrifugal motor 100b acting on the electronic device 200. For example, one of the centrifugal forces is upward perpendicular to the display screen of the electronic device 200, and the other centrifugal force is downward perpendicular to the display screen of the electronic device 200, which corresponds to one centrifugal force pulling upward and the other centrifugal force pulling downward. The two centrifugal forces are opposite in direction, so that the electronic device 200 can adjust the angle faster, for example, the electronic device 200 is located at the downward angle of the display screen and adjusted to the upward angle of the display screen faster, thereby preventing the display screen from colliding with the ground when the electronic device 200 lands on the ground, and reducing the probability of the display screen being broken.
Alternatively, in another embodiment, the first and second centrifugal motors 100a and 100b are fixed to two 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 two centrifugal forces have respective component forces that 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 have the same direction.

With this structure, two side-by-side 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 after one rotation of the rotating shaft 20. Specifically, the centrifugal force of the two pulses generated by the two centrifugal motors 100c may be in the same time period or in different time periods to adjust the angle of the electronic device 100a more quickly.

For example, the centrifugal forces generated by the at least two centrifugal motors 100d arranged side by side on the side close to the top camera of the electronic device 200b are both vertical to the display screen and upward, while the centrifugal forces generated by the at least two centrifugal motors 100d arranged side by side on the side close to the bottom key of the electronic device 200d are both vertical to the display screen and downward, and the forces in the two directions jointly act on the electronic device, so that the adjustment speed is faster. It is understood that the directions of the centrifugal forces generated by the at least two centrifugal motors 100d arranged side by side on the side close to the top camera of the electronic device 200b may not be exactly the same, as long as each centrifugal force has a component force with the same direction.

Alternatively, in various embodiments, three centrifugal motors may be disposed on one electronic device 200 c. 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 located side by side at the bottom of the electronic device 200c, as shown in fig. 14.

In other embodiments, the positions of the three centrifugal motors 100 on the electronic device 200 can be adjusted according to actual requirements. Specifically, the directions of the centrifugal forces generated by the three centrifugal motors 100 are the same as the setting principle of the above embodiment, and are mainly used for the purpose that the centrifugal forces jointly act on the electronic device 200 to accelerate the adjustment of the speed of the electronic device 200, which is not described herein again. Of course, other embodiments may provide a greater number of centrifugal motors 100 as desired.
The present application further provides a method for adjusting an angle of an electronic device during a dropping process of the electronic device, which is applied to the electronic device according to any one of the above embodiments, and as shown in fig. 16, the method includes:
101: and judging whether the electronic device is in a falling process.
In one embodiment, an acceleration sensor is provided in the electronic device, and if the acceleration sensor detects the generation of the gravitational acceleration, that is, if the electronic device is in a free-fall state, it is determined that the electronic device is in a fall state. Specifically, the different embodiments can be determined by the change of the gravity direction acceleration of the electronic device and the time for generating the acceleration. This is not described in detail.
102: if the electronic device is in a falling process, the centrifugal motor is started, so that a rotating block of the centrifugal motor generates centrifugal force to adjust the angle of the electronic device, and the preset surface of the electronic device faces to the preset collision object.
When the centrifugal motor is started, the rotating shaft rotates to drive the rotating block to eccentrically rotate, so that centrifugal force is generated, and the generated centrifugal force acts on the electronic device to enable the preset surface of the electronic device to face the preset collided object. In particular, the predetermined side of the electronic device is a relatively non-fragile or relatively impact-resistant side, such as the back side of the electronic device or the side with a protective cover. In different embodiments, a user can set a surface by himself or herself according to the actual structure of the electronic device, or a part is a preset surface. The colliding object, generally referred to as the ground, may be a wall or a trunk in other embodiments, such as when the user falls, and the electronic device is forced to be thrown away.
Fig. 17 is a schematic flow chart illustrating steps of the method in another embodiment, the method includes steps 201 to 204, where steps 201 and 202 are consistent with the above embodiment and are not repeated, and step 203 and step 204 are described in detail below:
201: and judging whether the electronic device is in a falling process.
202: if the electronic device is in a falling process, the centrifugal motor is started, so that a rotating block of the centrifugal motor generates centrifugal force to adjust the angle of the electronic device, and the preset surface of the electronic device faces to the preset collision object.
203: whether the electronic device is adjusted to enable the preset surface to face the preset collision object is judged.
The distance change between the preset surface and the preset collision object and the distance change between the surface opposite to the preset surface and the preset collision object are detected through the distance sensor, if the distance change between the preset surface and the preset collision object and the trend of the distance change between the surface opposite to the preset surface and the preset collision object are the same, for example, the distance change is smaller and smaller, and meanwhile, the distance between the preset surface and the preset collision object is smaller than the distance between the surface opposite to the preset surface and the preset collision object, the electronic device is judged to be adjusted to enable the preset surface to face the preset collision object. In other embodiments, the light condition may also be determined according to the above distance variation condition and the light condition of the predetermined surface and the surface position of the surface opposite to the predetermined surface. For example, if the distance between the predetermined surface and the predetermined collision object and the trend of the distance between the surface opposite to the predetermined surface and the predetermined collision object are the same, for example, the trends are smaller and smaller, and if the light on the surface of the predetermined surface is the light on the surface opposite to the predetermined surface, it is determined that the electronic device has been adjusted to make the predetermined surface face the predetermined collision object.
204: if yes, the centrifugal motor is turned off.
Because the electronic device is adjusted to enable the preset surface to face the preset collision object, the preset surface of the electronic device can touch the collision object instead of the fragile surface of the electronic device only by turning off the centrifugal motor, so that the electronic device is protected better.
The present application also provides a device with a storage function, which stores program data that, when executed, implements the method as described in the above embodiments. Specifically, the apparatus with a storage function may be one of a personal computer, a server, a network device, or a usb disk.
The above description is only for the purpose of illustrating embodiments of the present application and is not intended to limit the scope of the present application, and all modifications of equivalent structures and equivalent processes, which are made by the contents of the specification and the drawings of the present application or are directly or indirectly applied to other related technical fields, are also included in the scope of the present application.
