Description

Technical Field

[0001] This invention relates to the field of electronic drive technology, and more specifically, to a motor and an electronic device. Background Technology

[0002] In existing technologies, motors primarily drive the rotor through frictional motion between the stator and rotor. Because the stator and rotor of a motor require constant friction, severe wear can easily occur, affecting the motor's lifespan. Summary of the Invention

[0003] One objective of this invention is to provide a new technical solution for motors and electronic devices, which can at least solve the problem of severe wear of the stator and rotor of motors due to continuous friction in the prior art.

[0004] In a first aspect, the present invention provides a motor comprising: a support mechanism having a receiving cavity therein; a rotating shaft disposed within the receiving cavity and rotatable within the receiving cavity; a stator mechanism disposed within the receiving cavity, the stator mechanism including a bracket and a clamping assembly, the bracket being rotatably disposed within the receiving cavity, the clamping assembly being connected to the bracket and used to clamp or release the rotating shaft; and a first deformable material member disposed within the receiving cavity and connected to the bracket. When the clamping assembly clamps the rotating shaft, the first deformable material member deforms to drive the stator mechanism to rotate, static friction is formed between the clamping assembly and the rotating shaft, and the clamping assembly rotates synchronously with the rotating shaft. When the clamping assembly releases the rotating shaft, the first deformable material member contracts, the clamping assembly separates from the rotating shaft, and the rotating shaft rotates.

[0005] Optionally, the bracket includes: a connecting frame; two mounting frames, each mounting frame having a guide groove, both ends of the connecting frame being connected to one of the mounting frames, the first deformable material being connected to the mounting frame, each guide groove having a clamping assembly, and a portion of each clamping assembly extending out of the guide groove, the two clamping assemblies having their protruding sides from the guide grooves respectively clamping or releasing the rotating shaft from both radial sides.

[0006] Optionally, the clamping assembly includes: a second deformable material member disposed within the guide groove; and a clamping member, a portion of which extends into the guide groove and is connected to the second deformable material member, wherein the portion of the clamping member extending out of the guide groove is used to clamp or release the rotating shaft.

[0007] Optionally, the first deformable material component and the second deformable material component are both piezoelectric material components. When the first deformable material component receives a first signal and the second deformable material component receives a second signal, the second deformable material component extends and drives the clamping member to move toward the rotating shaft to clamp the rotating shaft. At the same time, the first deformable material component extends and drives the mounting bracket to rotate within the receiving cavity. Static friction is formed between the clamping member and the rotating shaft, and the clamping assembly rotates synchronously with the rotating shaft. When the first deformable material component disconnects from the first signal and the second deformable material component disconnects from the second signal, the second deformable material component retracts, the clamping member separates from the rotating shaft, the rotating shaft rotates, and the first deformable material component retracts.

[0008] Optionally, the first signal is a sinusoidal harmonic signal, and the second signal is a voltage square wave signal.

[0009] Optionally, one end of the clamping member extending out of the guide groove is an arc-shaped piece, the arc-shaped piece corresponding to the shape of the outer wall of the rotating shaft.

[0010] Optionally, the stator mechanism further includes: elastic vibrators, two elastic vibrators are respectively provided in each guide groove, the two elastic vibrators in each guide groove are respectively located on opposite sides of the second deformable material, and one end of each elastic vibrator is connected to the side wall of the guide groove, and the other end is connected to the clamping member.

[0011] Optionally, the support mechanism includes: a positioning frame, the positioning frame having an annular receiving cavity, the positioning frame having mating grooves communicating with the receiving cavity on opposite radial sides of the receiving cavity, a portion of the mounting frame extending out of the mating grooves, and the opening size of the mating grooves in the rotation direction of the mounting frame being larger than the thickness of the mounting frame.

[0012] Optionally, the mounting bracket is provided with two limiting pieces on opposite sides of the rotating shaft along the axial direction, the two limiting pieces are spaced apart to form a limiting groove, and the limiting groove corresponds to the groove wall of the mating groove.

[0013] Optionally, the inner wall of the positioning frame is provided with two first mounting slots, each first mounting slot being close to a corresponding mating slot, and one of the first mounting slots being located on the side of the mating slot facing the bottom of the mounting frame, and the other first mounting slot being located on the side of the mating slot facing the top of the mounting frame. Each first mounting slot is provided with a first deformable material component, and each first deformable material component is connected to the mounting frame.

[0014] Optionally, the inner wall of the positioning frame is further provided with two second mounting slots, each second mounting slot being close to a corresponding mating slot, and each second mounting slot and the first mounting slot being located on opposite sides of the mating slot. Each second mounting slot is provided with an elastic pad, and the elastic pad is connected to the mounting frame.

[0015] Optionally, the support mechanism further includes two covers, which are respectively disposed on opposite sides of the positioning frame to cover the receiving cavity.

[0016] A second aspect of the present invention provides an electronic device including the motor described in the above embodiments.

[0017] The motor of this invention, by incorporating a clamping assembly and a first deformable material component, achieves static friction between the clamping assembly and the shaft when the clamping assembly clamps the shaft. Simultaneously, the deformation of the first deformable material component drives the clamping assembly and the shaft to rotate synchronously. This ensures that the stator mechanism and the shaft are not affected by sliding friction, preventing severe wear and extending the motor's service life. When the clamping assembly releases the shaft, the clamping assembly separates from the shaft, eliminating contact friction and allowing the shaft to continue rotating. This ensures continuous shaft rotation during clamping and releasing, improving the motor's output efficiency and energy conversion efficiency.

[0040] The motor 100 according to an embodiment of the present invention will now be described in detail with reference to the accompanying drawings.

[0041] like Figures 1 to 2 As shown, the motor 100 according to an embodiment of the present invention includes a support mechanism 10, a rotating shaft 20, a stator mechanism 30, and a first deformable material component 40.

[0042] Specifically, the support mechanism 10 has a receiving cavity 111. A rotating shaft 20 is located within the receiving cavity 111 and is rotatable within it. A stator mechanism 30 is located within the receiving cavity 111 and includes a bracket 31 and a clamping assembly 32. The bracket 31 is rotatably located within the receiving cavity 111, and the clamping assembly 32 is connected to the bracket 31. The clamping assembly 32 is used to clamp or release the rotating shaft 20. A first deformable material member 40 is located within the receiving cavity 111 and is connected to the bracket 31. When the clamping assembly 32 clamps the rotating shaft 20, the first deformable material member 40 deforms to drive the stator mechanism 30 to rotate. Static friction is formed between the clamping assembly 32 and the rotating shaft 20, and the clamping assembly 32 rotates synchronously with the rotating shaft 20. When the clamping assembly 32 releases the rotating shaft 20, the first deformable material member 40 contracts, the clamping assembly 32 separates from the rotating shaft 20, and the rotating shaft 20 rotates.

[0043] In other words, see Figures 1 to 3 According to an embodiment of the present invention, the motor 100 mainly consists of a support mechanism 10, a rotating shaft 20, a stator mechanism 30, and a first deformable material component 40. Wherein, as... Figure 1 and Figure 2 As shown, the support mechanism 10 has a receiving cavity 111. A rotating shaft 20 is installed within the receiving cavity 111 and is rotatable within it. A stator mechanism 30 is installed within the receiving cavity 111. (See attached diagram.) Figure 3 The stator mechanism 30 includes a bracket 31 and a clamping assembly 32. The bracket 31 is rotatably disposed within the receiving cavity 111, and the clamping assembly 32 is connected to the bracket 31. The clamping assembly 32 can clamp or release the rotating shaft 20. A first deformable material member 40 is disposed within the receiving cavity 111 and is connected to the bracket 31. The first deformable material member 40 can drive the bracket 31 to rotate through deformation.

[0044] When the clamping assembly 32 clamps the rotating shaft 20, the first deformable material part 40 deforms, thereby driving the stator mechanism 30 to rotate. At this time, static friction is formed between the clamping assembly 32 and the rotating shaft 20, and the clamping assembly 32 and the rotating shaft 20 can rotate synchronously under the deformation drive of the first deformable material part 40, ensuring that the stator mechanism 30 and the rotating shaft 20 are not affected by sliding friction, preventing the stator mechanism 30 and the rotating shaft 20 from suffering severe wear, and helping to extend the service life of the motor 100.

[0045] When the clamping assembly 32 releases the rotating shaft 20, the first deformable material part 40 contracts, the clamping assembly 32 separates from the rotating shaft 20, and there is no contact friction between the clamping assembly 32 and the rotating shaft 20. The rotating shaft 20 can continue to rotate, ensuring that the rotating shaft 20 can rotate continuously throughout the entire process of clamping and releasing the clamping assembly 32, thereby improving the output efficiency and energy conversion efficiency of the motor 100. Simultaneously, in this invention, by using static friction to drive the stator mechanism 30 and the rotating shaft 20, the quiet operation of the motor 100 can also be guaranteed.

[0046] Therefore, according to the embodiment of the present invention, the motor 100, by providing a clamping assembly 32 and a first deformable material member 40, forms static friction between the clamping assembly 32 and the rotating shaft 20 when the clamping assembly 32 clamps the rotating shaft 20. Simultaneously, the deformation of the first deformable material member 40 drives the clamping assembly 32 and the rotating shaft 20 to rotate synchronously, ensuring that the stator mechanism 30 and the rotating shaft 20 are not affected by sliding friction, preventing severe wear of the stator mechanism 30 and the rotating shaft 20, and thus extending the service life of the motor 100. When the clamping assembly 32 releases the rotating shaft 20, the clamping assembly 32 separates from the rotating shaft 20, and there is no contact friction between the clamping assembly 32 and the rotating shaft 20. The rotating shaft 20 can continue to rotate, ensuring that the rotating shaft 20 can rotate continuously during the clamping and releasing process of the clamping assembly 32, thereby improving the output efficiency and energy conversion efficiency of the motor 100.

[0047] According to one embodiment of the present invention, the bracket 31 includes a connecting bracket 311 and two mounting brackets 312.

[0048] Specifically, each mounting bracket 312 is provided with a guide groove 3121, and the two ends of the connecting bracket 311 are respectively connected to a mounting bracket 312. The first deformable material part 40 is connected to the mounting bracket 312. Each guide groove 3121 is provided with a clamping component 32, and a part of each clamping component 32 extends out of the guide groove 3121. The two clamping components 32 can clamp or release the rotating shaft 20 from the radial sides of the rotating shaft 20 from the two sides of the guide groove 3121 respectively.

[0049] In other words, see Figure 2 and Figure 3 The bracket 31 mainly consists of a connecting frame 311 and two mounting frames 312. Each mounting frame 312 has a guide groove 3121. The two ends of the connecting frame 311 are connected to one mounting frame 312, and the connecting frame 311 can be configured as an arc-shaped frame. The first deformable material part 40 is connected to the mounting frame 312. Each guide groove 3121 has a clamping assembly 32, and a portion of each clamping assembly 32 extends out of the guide groove 3121. The two clamping assemblies 32, extending from the guide grooves 3121, can clamp or release the rotating shaft 20 from both radial sides, achieving static friction drive between the clamping assemblies 32 and the rotating shaft 20, reducing noise and wear, and ensuring smooth operation of the motor 100.

[0050] According to one embodiment of the present invention, the clamping assembly 32 includes a second deformable material part 321 and a clamping member 322.

[0051] Specifically, the second deformable material component 321 is disposed in the guide groove 3121. A portion of the clamping component 322 extends into the guide groove 3121 and is connected to the second deformable material component 321. The portion of the clamping component 322 extending out of the guide groove 3121 is used to clamp or release the rotating shaft 20.

[0052] In other words, see Figure 2 and Figure 3 The clamping assembly 32 mainly consists of a second deformable material part 321 and a clamping member 322. The second deformable material part 321 is installed within a guide groove 3121 and is expandable and contractible within the guide groove 3121. A portion of the clamping member 322 extends into the guide groove 3121 and is connected to the second deformable material part 321. The portion of the clamping member 322 extending out of the guide groove 3121 is used to clamp or release the rotating shaft 20. Through the expansion and contraction of the second deformable part, the clamping member 322 can be driven to clamp or release the rotating shaft 20, achieving continuous rotation of the rotating shaft 20.

[0053] According to one embodiment of the present invention, the first deformable material component 40 and the second deformable material component 321 are piezoelectric material components. When a first signal is input to the first deformable material component 40 and a second signal is input to the second deformable material component 321, the second deformable material component 321 extends and drives the clamping member 322 to move toward the rotating shaft 20 to clamp the rotating shaft 20. At the same time, the first deformable material component 40 extends and drives the mounting bracket 312 to rotate within the receiving cavity 111. Static friction is formed between the clamping member 322 and the rotating shaft 20, and the clamping assembly 32 rotates synchronously with the rotating shaft 20. When the first deformable material component 40 disconnects from the first signal and the second deformable material component 321 disconnects from the second signal, the second deformable material component 321 retracts, the clamping member 322 separates from the rotating shaft 20, the rotating shaft 20 rotates, and the first deformable material component 40 retracts.

[0054] In other words, the first deformable material component 40 and the second deformable material component 321 can be made of piezoelectric materials, and each component is a piezoelectric sheet. The piezoelectric material can stretch and deform when an electrical signal is applied. When the electrical signal is disconnected, the piezoelectric material contracts and returns to its original shape. Of course, those skilled in the art will understand and realize the extent of stretching and deformation of piezoelectric materials, and this will not be elaborated upon in detail here.

[0055] When a first signal is input to the first deformable material component 40 and a second signal is input to the second deformable material component 321, the second deformable material component 321 elongates and deforms under the action of the second signal. During the elongation of the second deformable material component 321, the clamping component 322 can be driven to move towards the rotating shaft 20, so that the clamping component 322 can clamp the rotating shaft 20. At the same time, the first deformable material component 40 elongates and deforms under the action of the first signal, and the elongation of the first deformable component can drive the mounting bracket 312 to rotate within the receiving cavity 111. Since the clamping component 322 clamps the rotating shaft 20 at this time, static friction is formed between the clamping component 322 and the rotating shaft 20, ensuring that the clamping assembly 32 can rotate synchronously with the rotating shaft 20, preventing severe wear problems between the stator mechanism 30 and the rotating shaft 20, and helping to extend the service life of the motor 100.

[0056] When the first deformable material component 40 disconnects from the first signal and the second deformable material component 321 disconnects from the second signal, the second deformable material component 321 contracts and recovers its deformation. During the contraction of the second deformable component, the clamping member 322 separates from the rotating shaft 20, allowing the rotating shaft 20 to continue rotating. Simultaneously, the first deformable material component 40 contracts and recovers its deformation, causing the stator mechanism 30 to return to its original state. By periodically inputting or disconnecting signals to the first deformable material component 40 and the second deformable material component, it is possible to ensure that the rotating shaft 20 of the motor 100 can rotate continuously without interruption, reducing wear, improving the energy conversion efficiency of the motor 100, and extending the service life of the motor 100.

[0057] In some specific embodiments of the present invention, the first signal is a sinusoidal harmonic signal and the second signal is a voltage square wave signal.

[0058] In other words, see Figure 4 and Figure 5 The first signal can be a sinusoidal harmonic signal, and the second signal can be a positive voltage square wave signal. The motor 100 of the present invention is a resonant piezoelectric rotary motor 100. The motor 100 can operate in a resonant state. By controlling the resonant signal, the motor 100 can operate at different frequencies or speeds, with smooth operation and a long service life.

[0059] like Figure 5 As shown, a square wave signal is input to the second deformable material component 321. When the time changes from t0 to t1, the second deformable material component 321 elongates and deforms, driving the clamping component 322 to move towards the rotating shaft 20 and lock the rotating shaft 20. When the time changes from t1 to t2, no square wave signal is input, the second deformable material component 321 contracts and recovers its deformation, the clamping component 322 resets, and the clamping component 322 separates from the rotating shaft 20.

[0060] like Figure 4 As shown, while a square wave signal is input to the second deformable material component 321, a sinusoidal harmonic signal is input to the first deformable material component 40. Similarly, when time changes from t0 to t1, the second deformable material component 321 elongates and deforms, which can push the mounting bracket 312 to rotate clockwise by a small angle; when time changes from t1 to t2, the first deformable material component 40 contracts and returns to its original state. Similarly, when time changes from t2 to t3, the actions from t0 to t1 are repeated.

[0061] Within one cycle, a positive voltage square wave signal is input to the second deformable material component 321, which drives the clamping component 322 to move and lock the rotating shaft 20. Simultaneously, a sine wave signal is input to the first deformable material component 40, which drives the mounting bracket 312 to rotate clockwise, thereby causing the rotating shaft 20 to rotate. When there is no input voltage to the second deformable material component 321, the clamping component 322 resets during the retraction of the second deformable material component 321, causing the stator mechanism 30 to separate from the rotating shaft 20. This process is repeated to achieve continuous clockwise rotation of the motor 100.

[0062] In some specific embodiments of the present invention, see Figure 2 and Figure 3 One end of the protruding guide groove 3121 of the clamping member 322 can be set as an arc-shaped piece, which corresponds to the shape of the outer wall of the rotating shaft 20, ensuring that the clamping member 322 can clamp the rotating shaft 20.

[0063] According to one embodiment of the present invention, such as Figure 3 As shown, the stator mechanism 30 also includes: elastic vibrators 33, two elastic vibrators 33 are respectively provided in each guide groove 3121, the two elastic vibrators 33 in each guide groove 3121 are respectively located on opposite sides of the second deformable material part 321, and one end of each elastic vibrator 33 is connected to the side wall of the guide groove 3121, and the other end is connected to the clamping member 322.

[0064] In other words, see Figure 3 The stator mechanism 30 also includes elastic vibrators 33. Two elastic vibrators 33 can be respectively installed in each guide groove 3121. The two elastic vibrators 33 in each guide groove 3121 can be located on opposite sides of the second deformable material member 321, with one end of each elastic vibrator 33 connected to the side wall of the guide groove 3121 and the other end connected to the clamping member 322. By setting the elastic vibrators 33, when a square wave signal is passed to the second deformable material member 321 and it undergoes elongation deformation, the elastic vibrators 33 move together with the clamping member 322 under the action of the second deformable material member 321, and the elastic vibrators 33 are stretched. When the signal input to the second deformable material member 321 is disconnected, the elastic vibrators 33 can quickly rebound, which helps the clamping member 322 to quickly release the rotating shaft 20 and improve the working efficiency of the motor 100.

[0065] According to one embodiment of the present invention, see Figure 1 and Figure 2 The support mechanism 10 includes a positioning frame 11, which has an annular receiving cavity 111. The positioning frame 11 has mating grooves 112 on opposite radial sides of the receiving cavity 111, communicating with the cavity. The mating grooves 112 are approximately located at the center of the annular receiving cavity 111. A portion of the mounting frame 312 can extend out of the mating groove 112, and the opening size of the mating groove 112 in the rotation direction of the mounting frame 312 is larger than the thickness of the mounting frame 312. This ensures that when the first deformable material part 40 receives an input signal, it can drive the mounting frame 312 to rotate a small angle within the opening of the mating groove 112, which facilitates the continuous rotation of the motor 100's shaft 20.

[0066] In some specific embodiments of the present invention, see Figure 2 and Figure 3 The mounting bracket 312 has two limiting pieces 3122 on opposite sides along the axial direction of the rotating shaft 20. The two limiting pieces 3122 can be spaced apart to form a limiting groove 3123, and the limiting groove 3123 corresponds to the groove wall of the mating groove 112. By providing the limiting groove 3123 on the outer side of the mounting bracket 312, it can be ensured that the mounting bracket 312 can rotate along the center of the positioning frame 11, which plays a guiding and limiting role in the rotation of the mounting bracket 312.

[0067] According to one embodiment of the present invention, see Figure 2 The inner wall of the positioning frame 11 is provided with two first mounting grooves 113, each located near a corresponding mating groove 112. One of the first mounting grooves 113 is located on the side of the mating groove 112 facing the bottom of the mounting frame 312, and the other first mounting groove 113 is located on the side of the mating groove 112 facing the top of the mounting frame 312. Each first mounting groove 113 can be provided with a first deformable material component 40, and each first deformable material component 40 is connected to the mounting frame 312 to ensure that when the two deformable material components are stretched and deformed, they can jointly drive the mounting frame 312 to rotate in the same direction (e.g., clockwise).

[0068] According to one embodiment of the present invention, such as Figure 2 As shown, the inner wall of the positioning frame 11 is also provided with two second mounting grooves 114. Each second mounting groove 114 can be respectively located near a corresponding mating groove 112, and each second mounting groove 114 and the first mounting groove 113 are respectively located on opposite sides of the mating groove 112. Each second mounting groove 114 is provided with an elastic pad 50, and the elastic pad 50 is connected to the mounting frame 312. When the first deformable material part 40 is given a signal and stretches and deforms, it pushes the mounting frame 312 to rotate and squeezes the elastic pad 50, causing the elastic pad 50 to deform. When the first deformable material part 40 is disconnected from the signal, the first deformable material part 40 contracts and returns to its original shape, and the elastic pad 50 can rebound, ensuring that the mounting frame 312 can quickly return to its original shape.

[0069] In some specific embodiments of the present invention, such as Figure 1 As shown, the support mechanism 10 also includes two covers 12, which are located opposite each other on the positioning frame 11. These covers can be used to close the receiving cavity 111. In this invention, the support mechanism 10 can be made of materials such as structural steel, stainless steel, aluminum alloy, magnesium alloy, and titanium alloy to ensure the overall structural strength of the support mechanism 10. The connecting frame 311 and mounting frame 312 of the stator mechanism 30 can also be made of materials such as stainless steel, aluminum alloy, magnesium alloy, and titanium alloy.

[0070] In summary, the motor 100 according to the embodiments of the present invention, by providing a clamping assembly 32 and a first deformable material member 40, forms static friction between the clamping assembly 32 and the rotating shaft 20 when the clamping assembly 32 clamps the rotating shaft 20. Simultaneously, the deformation of the first deformable material member 40 drives the clamping assembly 32 and the rotating shaft 20 to rotate synchronously, ensuring that the stator mechanism 30 and the rotating shaft 20 are not affected by sliding friction, preventing severe wear of the stator mechanism 30 and the rotating shaft 20, and thus extending the service life of the motor 100. When the clamping assembly 32 releases the rotating shaft 20, the clamping assembly 32 separates from the rotating shaft 20, and there is no contact friction between the clamping assembly 32 and the rotating shaft 20, allowing the rotating shaft 20 to continue rotating. This ensures that the rotating shaft 20 can rotate continuously during the clamping and releasing process of the clamping assembly 32, improving the output efficiency and energy conversion efficiency of the motor 100.
