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.
To better illustrate the present application, a centrifugal motor 100 for use in an electronic device is disclosed, and referring to fig. 1-3, the centrifugal motor 100 is capable of generating centrifugal force, such that the device on which the centrifugal motor 100 is mounted can be adjusted in angle by the centrifugal force. The centrifugal motor 100 includes a housing 10, a limiting member 12 and a rotating shaft 20 rotatably connected to the housing 10, a fixing sleeve 22 disposed on the rotating shaft 20, a rotating block 30 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 rotating shaft 20.
Specifically, in one embodiment, the housing 10 is elongated. The limiting member 12 is connected to the housing 10 through an adhesive layer or a snap fit, an outlet 124 is formed on the limiting member 12, the rotating shaft 20 is rotatably connected to the housing 10, a fixing sleeve 22 is disposed on the rotating shaft 20, the fixing sleeve 22 forms a containing cavity, and the fixing sleeve 22 is provided with an opening 224 communicated with the containing cavity. The rotating block 30 is received in the receiving cavity of the fixing sleeve 22 of the rotating shaft 20. 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.
With reference to fig. 4, the following explains the matching process between the components during one rotation of the rotating shaft 20: the rotation of the shaft 20 under the action of the driving mechanism 50 drives the fixing sleeve 22 and the rotation block 30 to rotate, so that the opening 224 of the fixing sleeve 22 is opposite to the outlet 124 of the position-limiting member 12. When the rotating block 30 is located in the fixing sleeve 22, the elastic member 40 is compressed by the rotating block 30, and when the opening 224 of the fixing sleeve 22 is opposite to the outlet 124 of the limiting member 12, the elastic member 40 is stretched to push the rotating block 30 to partially protrude out of the opening 224. So that the center of gravity of the rotating block 30 is deviated from the axis line of the rotating shaft 20, and a centrifugal force is generated due to the eccentric rotation of the rotating block 30 at this time. 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, and further the rotating block 30 compresses the elastic member 40 and moves toward the accommodating cavity of the fixed sleeve 22, so that the center of gravity of the rotating block 30 coincides with the axis of the rotating shaft 20, and as the rotating shaft 20 continues to rotate, when the opening 224 of the fixed sleeve 22 is not blocked by the limiting member 40, the compressed elastic member 40 releases energy, and pushes a part of the rotating block 30 to protrude out of the opening 224.
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 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. 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. 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 when the rotating shaft 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 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.
It will be appreciated that, with the above structure, the housing 10 and the limiting member 12 are not initially fixedly connected or integrally formed, but rather, the orientation of the outlet 124 of the limiting member 12 may be adjusted during installation according to the centrifugal force direction required by the device to which the centrifugal motor 100 is to be mounted, and then the limiting member 12 is connected to the housing 10 by an adhesive layer or a snap fit. Further, a centrifugal motor 100 capable of generating centrifugal forces in different directions may be assembled. For example, centrifugal motors 100 capable of producing different orientations may need to be installed in the same location or in different locations of an electronic device.
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, 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.
With reference to fig. 3, in an embodiment, the housing 10 is tubular, and the specific shape may be a cylinder or a rectangular parallelepiped, or other shapes, as long as the housing is provided with a cavity for a portion of the rotating shaft 20 to penetrate through. A portion of the rotating shaft 20 is inserted into the housing 10, and the fixing sleeve 22 on the rotating shaft 20 is located in the outlet 124 of the limiting member 12.
In an embodiment, referring to fig. 6, which is an assembled perspective view of the limiting clip 12 and the housing 10, the limiting member 12 includes a circular arc-shaped connecting member 126 contacting with an outer wall of the housing 10, and the adhesive layer 14 is disposed between the connecting member 126 and the housing 10. That is, after the outlet position of the limiting member 12 is adjusted according to the direction of the centrifugal force generated actually, the limiting member 12 is fixed on the outer surface of the housing 10 by the adhesive layer 14.
Meanwhile, referring to fig. 7, an exploded structure schematic view of the housing 10 and the limiting member 12 in another embodiment is shown, in this embodiment, at least two clamping slots 13 are formed around the housing 10, a portion of the limiting member 12 is clamped in one of the clamping slots 13 to connect the limiting member 12 to the housing 10, in this embodiment, two opposite clamping bodies 126a are clamped in one of the clamping slots 13. That is, after the outlet position on the limiting member 12 is adjusted according to the direction of the centrifugal force actually required to be generated, the engaging body 126a of the limiting member 12 is engaged with a corresponding one of the engaging slots 13, so as to connect the limiting member 12 to the housing 10. The axial lines of at least two slots 13 on the limiting member 12 are all parallel to the axial line of the rotating shaft 20, so that the rotating shaft 20 and the fixing sleeve 22 can be smoothly installed on the housing 10 and the limiting member 12, respectively.
Further, in another embodiment, a gap 16 is formed between the housing 10 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 housing 10 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 housing 10. It can be understood that, under the combined action of the first fixing ring 24 and the portion of the rotating shaft 20 located in the housing 10, it is ensured 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 located within the housing 10 and the first retaining ring 24 may be integrally formed or may be removably connected, such as by gluing or screwing. Such a connection is adopted to facilitate smooth mounting of the rotary shaft 20 on the housing 10. Taking the case of the threaded connection between the portion of the rotating shaft 20 located in the housing 10 and the first fixing ring 24 as an example, the first fixing ring 24 can 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 housing 10 is threaded through the housing 10 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 an embodiment, the housing 10 further includes a handle 18 integrally formed with the housing 10 and the position-limiting member 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 centrifugal motor 100 provided herein further includes a fastening member 60, and 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. The extension parts 34 are respectively provided with a fastening hole 342, the elastic member 40 is positioned in the through groove 262 of the first fixing ring 24 and/or the second fixing ring 26, and the fastening member 60 sequentially passes through the side wall of the first fixing ring 24 and/or the second fixing ring 26 and the elastic member 40 and is fastened in the fastening hole 342 of 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, and the overall volume is reduced. 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 within the housing 10 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. 8, the electronic device 200 is provided with at least two centrifugal motors according to the embodiments, which can generate a centrifugal force in a predetermined direction when the centrifugal motor is activated according to the requirements of the electronic device. And each centrifugal motor is provided with a distance sensor at the position for measuring the distance between the preset objects and the position where the electronic device is installed with the distance sensor. The centrifugal forces generated by the above-installed two centrifugal motors are opposite in direction. 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.
In one embodiment, electronic device 200 is rectangular and at least two centrifugal motors 100 are provided at different corner positions of electronic device 200, such as the opposite corners of the oblique side or the opposite corners of the side, as shown in fig. 8 and 9. With such a structure, since the centrifugal forces generated by the two centrifugal motors 100 or 100a are opposite in direction, the two centrifugal motors 100 or 100a can generate a pushing action and a pulling action relative to the screen of the electronic device 200 or 200a, so that the electronic device 200 or 200a can adjust the angle more quickly, and the screen is prevented from colliding with a preset collision object.
Referring to fig. 10, in another embodiment, two centrifugal motors 100b may be disposed at the same corner position, and the directions of the centrifugal forces generated by the two centrifugal motors 100b are opposite. With this structure, one centrifugal motor 100b can be selectively activated to generate centrifugal force according to the state of the electronic device 200 b. For example, if the electronic device 200b falls obliquely toward the ground, for example, it is detected that the screen of the electronic device 200b faces the ground, and the electronic device 200b falls obliquely so that one of the corners is closer to the ground than the other three corners, in this case, if two centrifugal motors 100b are disposed at the corner position closest to the ground, the centrifugal motor capable of generating a centrifugal force directed toward the ground may be activated so that the electronic device 200b adjusts the angle at a faster speed so that the back of the electronic device 200b lands. Specifically, how to detect whether the electronic device is falling, and whether the screen falls toward the collision object, and what posture the electronic device falls, will be described in detail below.
In other embodiments, if two centrifugal motors 100b are disposed at any one of the other three corner positions instead of the corner position closest to the ground when the screen faces the colliding object, the centrifugal motor 100b capable of generating the centrifugal force 100b in a direction away from the ground may be activated so that the electronic device 200b is angled at a faster speed so that the back of the electronic device 200b faces the ground. Specifically, whether the electronic device 200b is inclined to fall or not and which corner is closest to the ground may be at least at the corner position where the two centrifugal motors 100b are installed, and the diagonal positions corresponding to the corners where the two centrifugal motors 100b are installed are all provided with one distance sensor, the distances from the positions where the respective distance sensors are located, measured by the two distance sensors, to the ground (in other embodiments, the distance may be a wall or a trunk, etc.) are compared, and whether the electronic device 200b is inclined to fall or not is judged according to the distance relationship between the two corner positions and the ground. If so, which of the two corners is closer to the ground, and which centrifugal motor 100b is activated can be determined according to the direction of the centrifugal force generated by the centrifugal motors 100b at different positions.
Referring to fig. 11, in another embodiment, the electronic device 200c is rectangular, and the electronic device 200c includes three centrifugal motors 100c respectively located at three corners of the electronic device 200c, wherein the directions of the forces generated by at least two centrifugal motors 100c are opposite. If it is detected that the electronic device 200c falls parallel to the ground or the inclination angle is not large, the three centrifugal motors 100c are simultaneously activated to form a push-pull effect, wherein the push force is larger than the pull force, or the pull force is larger than the push force, so that the electronic device 200c adjusts the angle at a faster speed, and the back of the electronic device 200c lands on the ground.
Further, if it is detected that the electronic device 200c falls toward the ground with a larger inclination angle, it is determined which centrifugal motors 100c are activated according to the magnitude relationship between the respective corner positions and the distance from the ground, which are detected by the distance sensors corresponding to the positions of the centrifugal motors 100 c. Taking the distribution of the three centrifugal motors 100C shown in fig. 11 as an example, assuming that the position of the corner a of the electronic device is closer to the ground than the positions of the corners of the other two centrifugal motors 100C, the direction of the centrifugal force generated by the centrifugal motor 100C at the corner a is far away from the screen and faces the ground, and the direction of the centrifugal force generated by the centrifugal motor 100C at the corner B is far away from the ground, the centrifugal motors 100C at the corners a and B are both started to form a push-pull effect, and the centrifugal motor 100C at the corner C is started to increase the push force or increase the pull force at the same time no matter the centrifugal force generated by the centrifugal motor 100C is towards the ground or away from the ground, so that the electronic device 200C can adjust the angle more quickly to avoid the screen from being grounded. It is understood that if the other centrifugal motor 100C is located not at the corner C but at the corner D, it can be simultaneously activated to increase the pushing force or increase the pulling force regardless of whether the centrifugal force generated therefrom is directed toward the ground or away from the ground.
In contrast, in another embodiment, if it is determined that the centrifugal motor 100C at the corner a of the electronic device 200C is located closer to the ground than the other two centrifugal motors 100C, the direction of the centrifugal force generated by the centrifugal motor 100C at the corner a is far away from the ground, and the direction of the centrifugal force generated by the centrifugal motor 100C at the corner B is far away from the screen and toward the ground by the above-described method, it may be determined which centrifugal motors 100C are activated according to the direction of the centrifugal force generated by the centrifugal motor 100C at the corner C. If the direction of the centrifugal force generated by the centrifugal motor 100C located at the corner C is away from the ground direction, the centrifugal motor 100C located at the corner C is started, and the centrifugal motors 100C located at the positions a and B are not started. And if the direction of the centrifugal force generated by the centrifugal motor 100C at the corner position of the C is towards the ground, all the three centrifugal motors 100C are started, although the electronic device 200C needs to turn over a large bucket to adjust the screen to deviate from the ground through adjustment of the direction, the three centrifugal motors 100C are started together, so that the force can be increased, the adjustment is accelerated, and finally the screen of the electronic device 200C can also be adjusted to deviate from the ground.

The distance sensors are distributed on the four corners respectively, so that the corner which is closer to the ground can be more accurately judged.

Wherein the front distance sensor 140 and the rear distance sensor 130 are used to measure the distance between the two distance sensors from a predetermined collision.

On the contrary, if the distance from the position of the front distance sensor 140 to the preset collision object is greater than the distance from the position of the rear distance sensor 130 to the preset collision object, it is determined that the electronic device 200e does not face the preset collision object for the screen.

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.

On the contrary, if the distance from the position where the front distance sensor is located to the preset collision object is greater than the distance from the position where the rear distance sensor is located to the preset collision object, it is determined that the electronic device does not face the preset collision object for the screen.

That is, if it is determined in step 303 that the screen of the electronic device faces the preset collision object, it is further determined which centrifugal motor is located at a corner closer to the preset collision object according to the distance between the preset collision objects and the distance measured by the distance sensor at the corner of each centrifugal motor, and finally it is determined which centrifugal motor is activated according to whether the direction of the centrifugal force generated by the centrifugal motor faces the preset collision object or not and the direction of the centrifugal force generated by the other centrifugal motors.
