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 rotating shaft 20 rotatably connected to the housing 10, a fixing sleeve 22 disposed on the rotating shaft 20, at least two rotating blocks 30 accommodated in the fixing sleeve 22, at least one set of magnetic coils disposed in the fixing sleeve or on the housing, and a driving mechanism 50 rotatably connected to the rotating shaft 20.
Specifically, in one embodiment, 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 a receiving cavity, and the fixing sleeve 22 is provided with at least two openings 224 communicating with the receiving cavity. In one embodiment, a support member 142 is disposed on the housing 10, and a portion of the support member 142 is located opposite to the outlet 124 of the position-limiting member 12, and the support member 142 is used for fixing the magnetic coil 70. Fig. 5 shows a schematic view of the sleeve 14 extending out of the support 142. In other embodiments, the magnetic coil 70 may be fixed to the bottom of the holster 22 opposite the opening 224. At least two rotating blocks 30 are accommodated in the fixing sleeve 22, and the at least two rotating blocks 30 are magnetic bodies and respectively correspond to the two openings 224 one by one. 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.
Meanwhile, referring to fig. 4, the following description explains the matching process between the components during one rotation of the shaft 20, taking the two rotating blocks 30 as an example, and the magnetic coil 70 fixed at the bottom of the fixed sleeve 22: under the action of the driving mechanism 50, the rotating shaft 20 rotates relative to the housing 10, and since the two rotating blocks 30 are magnetic bodies, the magnetic coil 70 generates periodic repulsive force and attractive force to act on the two rotating blocks 30, so that the two rotating blocks 30 are simultaneously or sequentially positioned outside the opening 224 periodically, and further the center of gravity of the rotating blocks 30 is periodically deviated from the axis line of the rotating shaft 20. When the magnetic coil 70 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 70 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.
When the rotating block 30 is partially located outside the opening 224 during the rotation of the rotating shaft 20, a centrifugal force is generated due to the gravity center of the rotating block 30 deviating from the axial line of the rotating shaft 20, the electronic device of the centrifugal motor 100 is applied, the rotating shaft 20 can be rotated during the process of detecting the falling of the electronic device, the angle of the electronic device is adjusted by using the centrifugal force generated by the centrifugal motor 100, 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.
In contrast, in the embodiment in which the magnetic coil 70 is located on the support 142 of the housing 10, with reference to fig. 5, the pivoting block 30 partially protrudes out of the opening 224 of the pouch 22 by the attractive force of the magnetic coil 70 and retracts into the pouch 22 by the pushing force of the magnetic coil 70 after a short period of time, and so on. The specific principle process is similar to the case that the magnetic coil 70 is fixed in the fixing sleeve 22, and the detailed description is omitted.
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. 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 then the rotating block 30 generates a centrifugal force along with the rotation of the rotating shaft 20.
Referring to fig. 6, a schematic diagram of a centrifugal force generated by one rotating block 30 when the rotating shaft 20 rotates one circle is shown, in this embodiment, when the rotating shaft rotates to 270 degrees to 360 degrees, a portion of one 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 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 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.
During one rotation of the rotating shaft 20, two centrifugal forces are generated by the two rotating blocks 30, wherein the two centrifugal forces may be generated simultaneously or sequentially separated from each other in different embodiments, that is, a center-to-center line of the two openings 224 is parallel to the axis of the rotating shaft 20, or the two openings 224 are different from each other by a predetermined phase. For example, in one embodiment, the predetermined phase of the two openings 224 in the stationary sleeve 22 is 90 °, and if one of the rotating blocks 30 is partially outside the openings 224 for 1/4 rotations of the shaft, and the predetermined phase of the corresponding opening 224 of the two rotating blocks 30 is 90 °, half of the time during one rotation of the shaft 20 generates centrifugal force, as shown in fig. 7. Further, in other embodiments, the number of the rotating blocks 30 may be increased according to actual requirements to generate a larger centrifugal force; or by providing more rotating blocks 30, the centrifugal force is generated all the time during the rotation of the rotating shaft 20, or more time periods are generated.
In other embodiments, the preset phase of two adjacent openings 224 may be any value from 0 to 90 °, and when the preset phase of the two openings 224 is 0 degrees, the two openings 224 are arranged side by side, as shown in fig. 3. In this embodiment, the centrifugal force generated by two rotating blocks 30 during one rotation of the rotating shaft 20 is twice the centrifugal force generated by a single rotating block 30.
By adopting the structure of at least two rotating blocks 30, the centrifugal force generated by the centrifugal motor can be greatly increased, and the opening 224 with the 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, when the two openings 224 of the pouch 22 are not of the same phase, the magnetic coils 70 comprise two sets of one rotating block 30 for each set of magnetic coils 70, such that a portion of one rotating block 30 entering and exiting the openings 224 is controlled by the force generated by the corresponding set of magnetic coils 70.
In one implementation, with reference to fig. 3 and 8, the centrifugal motor 100 further includes a limiting member 12. Specifically, the limiting member 12 includes two arc claws 122 oppositely disposed, the two 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 are communicated with each other, in one 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 at two sides of the axis direction of the rotating shaft 20, 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 summary, the position-limiting element 12 serves to fix and limit the rotating shaft 20 and the fixing sleeve 22, and when the outlet 124 of the position-limiting element 12 is slightly larger than the width of the rotating block 30 located at the outer portion of the opening 224, the position-limiting element 12 can also assist the rotating block 30 to enter the fixing sleeve 22, as will be described below.
The portion of the rotation block 30 outside the opening 224 is surrounded by the two arc claws 122, and when the opening of the position-limiting member 12 is slightly larger than the width of the rotation block 30 outside the opening 224, there may occur a case where the rotation block 30 is not moved toward the fixed sleeve 22 by the repulsive force or the tensile force of the magnetic coil due to inertia. The portion of the rotating block 30 located in the opening 224 contacts the arc claws 122 during the rotation of the rotating shaft 20, and the arc claws 122 press the rotating block 30, thereby moving the rotating block 30 toward the fixed sleeve 22.
In one embodiment, the first and second retaining rings 24, 26 are annular, and have a through-slot 262 therebetween for receiving the rotating block 30.
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 opening 224 to prevent the entire rotating block 30 from extending out of the holster 22, or to prevent a substantial portion of the volume of the rotating block 30 from extending out of the holster 22 and becoming difficult to return to the holster 22. In other embodiments, the rotating block 30 may have other shapes, such as an elongated shape and a cylindrical shape, and the length of the opening portion through which the rotating block 30 can extend is controlled by 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 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 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 driving mechanism 50 may be other types of electric machines capable of generating power, such as a 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. In another embodiment, the component force of the centrifugal force generated by each of the centrifugal forces generated by the rotating blocks 30 of the two centrifugal motors 100c may be the same in 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 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.
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. 13, in a further embodiment, at least two centrifugal motors 100d are respectively disposed side by side on two opposite sides of the electronic device 200b in the length direction, or on two opposite sides of the electronic device 200b 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 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. 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 200b 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 200 b.
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 another embodiment, a first centrifugal motor 100g is located at the top of the electronic device 200d, 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 200c, as shown in fig. 15. 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.
