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, and a driving mechanism 50 rotatably connected to the shaft 20.
Specifically, in the first embodiment of the present application, the limiting member 12 is disposed on the casing 10, the limiting member 12 is provided with an outlet 124, and the casing 10 is further provided with a permanent magnet 70 or a magnetic coil (not shown) opposite to the outlet 124. The shaft 20 is rotatably connected to the housing 10, the shaft 20 is provided with a fixing sleeve 22, the fixing sleeve 22 forms an accommodating cavity, and the fixing sleeve 22 is provided with an opening 224 communicating with the accommodating cavity. The rotating block 30 is accommodated in the accommodating cavity of the fixing sleeve 22 of the rotating shaft 20, and further, the bottom of the fixing sleeve 22 is communicated with the outlet 124 of the limiting member in the embodiment shown in fig. 4, and the fixing sleeve 22 may also be provided with a bottom in other embodiments. Specifically, the rotating block 30 is a magnetic body, such as a metal block, a permanent magnet, or a permanent magnet disposed inside the rotating block 30. And a portion of the rotating block 30 is positioned outside the opening 224 such that the center of gravity of the rotating block 30 is offset from the axis of the rotating shaft 20. The driving mechanism 50 is connected to the shaft 20, so as to rotate the shaft 20 and drive the fixing sleeve 22 and the rotating block 30 to rotate relative to the housing 10.
With reference to fig. 4, the following explains the matching process between the components during one rotation of the rotating shaft 20: the permanent magnet 70 or the magnetic coil fixed to the housing 10 generates an attractive force to the rotary block 30, so that the rotary block 30 is partially positioned outside the opening 224, under the action of the driving mechanism 50, the rotating shaft 20 rotates relative to the housing 10, when the rotating shaft 20 starts to rotate, a part of the rotating block 30 is located outside the opening 224 of the fixed sleeve 22, and as the rotating shaft 20 rotates, the rotating block 30 also rotates, so that the part of the rotating block 30 located outside the opening 224 abuts against the limiting member 12, thereby the limiting member 12 presses the rotating block 30, further, the rotating block 30 is far away from the permanent magnet 70 or the magnetic coil and moves towards the accommodating cavity of the fixed sleeve 22, so that the center of gravity of the rotating block 30 is coincided with the axial lead of the rotating shaft 20, and with the continuous rotation of the rotating shaft 20, when the opening 224 of the fixing sleeve 22 is not blocked to the outside by the restraining member 40, the rotation block 30 is partially located outside the opening 224 again by the magnetic attraction of the permanent magnet 70 or the magnetic coil.
Assuming that the time of one rotation of the rotating shaft 20 is one period, a part of the rotating block 30 is located outside the opening 224 during a part of the one 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 30 is far away from the permanent magnet 70 or the magnetic coil and enters the accommodating cavity of the fixed sleeve 22. 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 as the rotating shaft 20 rotates. The electronic device using the centrifugal motor 100 can rotate the rotating shaft 20 when the electronic device is detected to fall, and the centrifugal force generated by the centrifugal motor 100 is used to adjust the angle of the electronic device, so that the preset surface of the electronic device faces 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.
Referring to fig. 5, which is a schematic diagram illustrating the centrifugal force generated by the rotating block 30 when the rotating shaft 20 rotates for one rotation, in this embodiment, when the rotating shaft 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 whole rotating block 30 is positioned in the accommodating cavity, and the gravity center of the rotating block 30 is superposed with the axis line of the rotating shaft 20, so that the rotating block 30 does not generate centrifugal force in the period of time. That is, the rotating block 30 generates a pulse of centrifugal force for every rotation of the rotating shaft 20. The electronic device requires at least one pulse of centrifugal force or a plurality of pulses of centrifugal force during the angle adjustment process.
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. 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 process, and the arc claw 122 presses the rotating block 30, so that the rotating block 30 moves into the fixed sleeve 22. 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 just passes through to start the rotation of the rotating shaft 20, and the portion of the rotating block 30 outside the opening 224 immediately contacts the arc-shaped claw 122. 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.
In one embodiment, a support member 142 extends from the sleeve 14 or the retaining member 12, and a portion of the support member 142 is located opposite the outlet 122 of the retaining member 12, and the support member 142 is used to fix the permanent magnet 70 or the magnetic coil. Fig. 3 shows a schematic view of the sleeve 14 extending out of the support 142.
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 a first fixing ring 24 in the axial direction of the rotating shaft 20, and the first fixing ring 24 is located in the gap 16, so that the first fixing ring 24 is 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 axis direction of the rotating shaft 20, the first fixing ring 24 is located in the notch 16, and the circular 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 located within the sleeve 14 and the first retaining ring 24 may be integrally formed or may be removably connected, such as by gluing or screwing, in order to facilitate easy mounting of the 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 present application provides a centrifugal motor 100 in which the width of the portion of the rotating block 30 located in the receiving cavity of the fixing sleeve 22 is larger than the width of the opening 224 of the fixing sleeve 22, so as to prevent the rotating block 30 from being pulled out of the fixing sleeve 22 by the attraction force of the permanent magnet 70 or the magnetic coil. In the embodiment shown in fig. 3, the rotating block 30 includes a base 32 and an extension 34 extending from the base 32 in the axial direction of the rotating shaft 20. Wherein the width of the extension 34 is greater than the width of the opening 224 of the retainer sleeve 22. In other embodiments, the rotating block 30 may have other shapes, such as a cylinder or an irregular long bar.
In this embodiment, the driving mechanism 50 is a magnetic coil, and the rotating shaft 20 is partially sleeved in the driving mechanism 50 of 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. It should be noted that the magnetic coils are located inside the sleeve 14, unlike the magnetic coils on the support 142.
Alternatively, in other embodiments, the driving mechanism 50 may be other types of electric machines capable of generating power, such as a motor.
Referring to fig. 7 and 8, in the second embodiment of the present application, the difference between the present embodiment and the first embodiment is that the housing 10 of the centrifugal motor 200 is not provided with a limiting member, and the housing 10 is not provided with a permanent magnet or a magnetic coil, but the magnetic coil 80 is provided at the bottom of the fixing sleeve 22 opposite to the opening 224. Since the rotating block 30 is a magnetic body, the magnetic coil 80 generates a periodic repulsive force and an attractive force to act on the rotating block 30, so that the periodic portion of the rotating block 30 is positioned outside the opening 224, and the center of gravity of the rotating block 30 is periodically deviated from the axis line of the rotating shaft 20. When the magnetic coil 80 generates a repulsive force to the rotating block 30, the rotating block 30 is repelled by the repulsive force, and a part of the repulsive force is positioned 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, when the magnetic coil 80 generates an attraction force to the rotating block 30, the rotating block 30 is pulled back into the fixed sleeve 22 by the attraction force, and the center of gravity of the rotating block 30 coincides with the axis of the rotating shaft 20.
That is, for every rotation of the shaft 20, the rotating block 30 will be partially located outside the opening 224 of the fixed sleeve 22 within an angular range. When the center of gravity of the rotating block 30 is deviated from the axis line of the rotating shaft 20 with a portion located outside the opening 224, a pulse of centrifugal force is generated, that is, the rotating block 30 generates a pulse of centrifugal force per one rotation of the rotating shaft 20. The electronic device requires at least one pulse of centrifugal force or a plurality of pulses of centrifugal force during the angle adjustment process. As in the description related to the first embodiment above, this is not repeated.
Further, in other embodiments, the magnetic coil 80 may be disposed in the first fixing ring 24 and/or the second fixing ring 24 below the extension portion 34 of the rotating block 30, or both the first fixing ring 24 and/or the second fixing ring 24 and the bottom of the fixing sleeve 22 may be disposed with the magnetic coil 80.
In other embodiments, the position-limiting element can be changed into a supporting element for supporting the fixing sleeve without abutting against the rotating block.
As shown in fig. 9 and 10, in the third embodiment of the present application, the difference between the present embodiment and the first embodiment is: the housing 10 of the centrifugal motor 300 retains the position-limiting element 12, but instead of providing a permanent magnet or a magnetic coil on the housing 10, a permanent magnet 90 or a magnetic coil (not shown) is provided in the fixing sleeve 22 at a position opposite to the opening 224. And the rotating block 30 is also a magnetic body, different from the above embodiment, the permanent magnet 90 or the magnetic coil in this embodiment generates a repulsive force to act on the rotating block 30, so that the rotating block 30 is partially positioned outside the opening 224, and further, the center of gravity of the rotating block 30 is periodically deviated from the axis line of the rotating shaft 20; the rotation of the shaft 20 drives the rotation block 30 to rotate, and the position-limiting member 12 pushes the rotation block 30 to move toward the fixed sleeve 22, so that the center of gravity of the rotation block 30 coincides with the axis of the shaft 20, and the rotation block 30 is partially positioned outside the opening 224 again by the repulsive force generated by the magnetic coil or the permanent magnet 90 as the shaft 20 continues to rotate. The description of the related principles is the same as the other embodiments above, and is not repeated here.
It will be appreciated that in one embodiment, the rotating blocks 30 themselves are permanent magnets if permanent magnets 90 are disposed within the stationary sleeve 22, or the rotating blocks 30 containing permanent magnets are magnetically repelled from the permanent magnets 90 within the stationary sleeve 22, such that the rotating blocks 30 are always repelled. In another embodiment, a magnetic coil is disposed in the fixed sleeve 22, and the magnetic coil can be controlled to generate a repulsive force to the rotating block 30 at all times, or can be controlled not to generate a repulsive force to the rotating block 30 for a short period of time during one rotation of the rotating shaft 20, for example, when the rotating block 30 needs to move back into the fixed sleeve 22.
Further, in other embodiments, the permanent magnet 90 or the magnetic coil may be disposed in the first fixing ring 24 and/or the second fixing ring 24 below the extension portion 34 of the rotating block 30, or both the permanent magnet 90 or the magnetic coil may be disposed at the bottom of the first fixing ring 24 and/or the second fixing ring 24 and the fixing sleeve 22.
Referring to fig. 11, the present application further provides an electronic device 400, wherein the electronic device 400 has the centrifugal motor 100, 200 or 300 as described in any of the above embodiments. Specifically, the electronic device 400 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. 12, optionally, in an embodiment, the centrifugal motor 100 installed in the electronic device 400a 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 400a in the length direction, and the centrifugal forces generated by the rotating blocks 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 400a is opposite to the centrifugal force generated by the second centrifugal motor 100b acting on the electronic device 400 a. For example, one of the centrifugal forces is upward perpendicular to the display screen of the electronic device 400a, and the other centrifugal force is downward perpendicular to the display screen of the electronic device 400a, 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 400a can adjust the angle more quickly, for example, the electronic device 400a is positioned at the downward angle of the display screen and adjusted to the upward angle of the display screen more quickly, thereby preventing the display screen from colliding with the ground when the electronic device 400a 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 400b in the width direction, as shown in fig. 13.
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. 14, in another embodiment, at least two centrifugal motors 100c are mounted on an electronic device 400c, 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. In another embodiment, the centrifugal forces generated by the rotating blocks of the two centrifugal motors 100c may have the same component force in at least one 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. 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.
It is understood that, in other embodiments, three or more centrifugal motors 100c may be arranged side by side, and this is not particularly limited.
Referring to fig. 15, in a further embodiment, at least two centrifugal motors 100d are respectively disposed side by side on two opposite sides of the electronic device 400d in the length direction, or two opposite sides of the electronic device 400d in the width direction, and the centrifugal forces generated by the side-by-side centrifugal motors 100d on the same side have at least component forces in the same direction, while the centrifugal force generated by the side-by-side centrifugal motor 100e on the other side is in the opposite direction to the centrifugal force generated by the side-by-side centrifugal motor 100d on the one side. 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 400d 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 400d 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 can be understood that the directions of the centrifugal forces generated by the at least two centrifugal motors 100d arranged side by side near the top camera of the electronic device 400d may not be exactly the same, as long as each centrifugal force has a component force with the same direction. The centrifugal forces generated by at least two centrifugal motors disposed side by side near the bottom key of the electronic device 100b may not be completely the same, which is not described herein.
It is understood that, in one embodiment, the component of the centrifugal force generated by the side-by-side centrifugal motor 100e on the other side of the electronic device 400d is opposite to the component of the centrifugal force generated by the side-by-side centrifugal motor 100d on the one side of the electronic device 400 d.
Alternatively, in various embodiments, three centrifugal motors may be disposed on one electronic device 400 e. For example, in one embodiment, one centrifugal motor 100f is located at the top of the electronic device 400e, and the other two centrifugal motors 100f are located side by side at the bottom of the electronic device 400e, as shown in fig. 16. In another embodiment, a first centrifugal motor 100g is located at the top of the electronic device 400f, a second centrifugal motor 100g is located at the bottom of the electronic device 200c, and a third centrifugal motor 100g is located at the middle edge of the electronic device 400f, as shown in fig. 17. 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. 18, 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. 19 is a schematic flow chart of 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 with emphasis on:
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.
