[0002] With the vigorous development of the mobile phone industry, the form of mobile phones is constantly changing. The camera is one of the important devices in the mobile phone. At present, the long-focus camera with high optical zoom capability has gradually become a trend. The zoom ratio of the camera is more and more diversified, and the size of the camera is also getting larger. The application of large-angle anti-shake and long-focus macro causes the camera lens to need more and more working moving space in the module cavity. However, when the camera is not working, the lens and the anti-shake module are in a free and uncontrolled state in the module cavity. When the user shakes the mobile phone, the lens and the anti-shake module freely swing in the cavity and hit the cavity to produce abnormal noise. The abnormal noise increases with the increase of the cavity space and the weight of the lens and the anti-shake module. CONTENT OF THE UTILITY MODEL

The first magnetic piece is arranged on the circumferential side of the carrier. The connecting plate is arranged on the inner wall of the base, and the connecting plate and the first magnetic piece form an accommodation space. The thermal deformation piece is filled in the accommodation space.

[0007] When the second magnetic piece is powered on, the heat generated by the second magnetic piece heats the thermal deformation piece to a liquid state. The second magnetic piece drives the carrier to move relative to the base through the first magnetic piece. When the second magnetic piece is powered off, the thermal deformation piece changes to a solid state. The thermal deformation piece fastens the first magnetic piece and the connecting plate when the thermal deformation piece is in the solid state.

[0011] The circuit board is mounted on the base and electrically connected with the connecting plate.

[0012] In a third aspect, the embodiments of the present application provide an electronic device, including the motor or the camera module.

[0013] In the embodiments of the present application, when the second magnetic member is powered on, the first magnetic member is free due to the heating of the thermal deformation member to a liquid state by the heat generated by the second magnetic member, the second magnetic member can drive the carrier to move relative to the base through the first magnetic member, so that the position of the carrier can be adjusted, and at least one of the focusing and the anti-shake function of the camera module is realized, so as to improve the shooting effect.

[0025] The following will be described in detail Figure 1 - Figure 4 The motor, camera module and electronic device described in the embodiments of the present application are described.

[0026] In a first aspect, as Figure 1 and Figure 2As shown, the motor disclosed in the embodiments of the present application comprises a base 1, a carrier 2 and an anti-shake assembly 3 arranged in the base 1, wherein the anti-shake assembly 3 comprises a thermal deformation piece 31, a first magnetic piece 32, a connecting plate 33 and a second magnetic piece 34 arranged on the connecting plate 33, the first magnetic piece 32 is arranged on the circumferential side of the carrier 2, the connecting plate 33 is arranged on the inner wall of the base 1, and the connecting plate 33 and the first magnetic piece 32 enclose a containing space 35, and the thermal deformation piece 31 is filled in the containing space 35; when the second magnetic piece 34 is powered on, the heat generated by the second magnetic piece 34 heats the thermal deformation piece 31 to a liquid state, and the second magnetic piece 34 drives the carrier 2 to move relative to the base 1 through the first magnetic piece 32; when the second magnetic piece 34 is powered off, the thermal deformation piece 31 converts to a solid state, and the thermal deformation piece 31 fastens the first magnetic piece 32 and the connecting plate 33 when in the solid state.

[0027] In the embodiments of the present application, when the second magnetic piece 34 is powered on, the thermal deformation piece 31 is heated to a liquid state by the heat generated by the second magnetic piece 34, so that the first magnetic piece 32 is free, and the second magnetic piece 34 can drive the carrier 2 to move relative to the base 1 through the first magnetic piece 32, so that the position of the carrier 2 can be adjusted, and at least one of the focusing and anti-shake functions of the camera module is realized, so as to improve the shooting effect. When the second magnetic piece 34 is powered off, the thermal deformation piece 31 converts to a solid state, and the thermal deformation piece 31 can fasten the first magnetic piece 32 and the connecting plate 33, so that the movement of the first magnetic piece 32 is limited, and the movement of the carrier 2 is also limited, so that abnormal sound of the carrier 2 during non-use can be avoided, and the problem of abnormal sound of the camera module when the electronic device shakes can be solved.

[0028] It can be understood that the motor described in the embodiments of the present application can be applied in a camera module, wherein the base 1 is a fixed component in the motor, the carrier 2 is a moving component in the motor, and the carrier 2 can be used to mount and fix a lens 6, and the anti-shake assembly 3 can serve as a driving unit of the carrier 2, so that the carrier 2 can move relative to the base 1.

[0029] Specifically, the anti-shake assembly 3 comprises the first magnetic piece 32 and the second magnetic piece 34, and the cooperation of the second magnetic piece 34 and the first magnetic piece 32 can drive the carrier 2 to move relative to the base 1, and at least one of the focusing function and the anti-shake function of the lens 6 can be realized.

[0030] Specifically, the second magnetic member 34 can be an electromagnetic member, and can generate a magnetic field to exert a magnetic force on the first magnetic member 32 when the second magnetic member 34 is powered on, and the magnetic force disappears when the second magnetic member 34 is powered off. For example, the second magnetic member 34 can be a coil or an electromagnet, and the first magnetic member 32 can be a magnetic metal member such as iron, nickel, cobalt, and their alloys.

[0031] Specifically, the connecting plate 33 can be a circuit board for arranging the second magnetic member 34 and realizing electrical connection of the second magnetic member 34. In the embodiment of the present application, the specific connection mode is not limited.

[0032] Specifically, the first magnetic member 32 is fixedly installed on the carrier 2, and the specific installation mode is not limited in the embodiment of the present application.

[0033] Specifically, the thermal deformation member 31 can be converted into a liquid state at a high temperature and into a solid state at a low temperature. The thermal deformation member 31 can be made of a phase change material, including paraffin, non-paraffin organic matter, hydrated salt, metal, and low-melting eutectic salt. Among many phase change materials, paraffin has the advantages of wide optional melting point range, high latent heat of phase change, non-toxicity, non-corrosiveness, and stable physical and chemical properties.

[0034] Further, the thermal deformation member 31 can have an encapsulation film to encapsulate the phase change material, so that the thermal deformation member 31 can be prevented from leaking when it is converted into a liquid state, and the encapsulation film does not limit the shape of the thermal deformation member 31. The specific material of the encapsulation film is not limited in the embodiment of the present application. The thermal deformation member 31 can be limited in the accommodating space 35 and not connected with the connecting plate 33 or the first magnetic member 32, or at least part of the encapsulation film can be connected with the connecting plate 33 or the first magnetic member 32, and the specific connection mode is not limited in the embodiment of the present application.

[0035] Specifically, the carrier 2 is arranged in the base 1, the first magnetic member 32 can be arranged on the circumferential side of the carrier 2, the connecting plate 33 can be arranged on the inner wall of the base 1, the connecting plate 33 is arranged opposite to the first magnetic member 32 and can enclose the accommodating space 35, and the thermal deformation member 31 can be filled in the accommodating space 35. The second magnetic member 34 can be arranged close to the accommodating space 35, so that the second magnetic member 34 can generate a magnetic force on the first magnetic member 32 when the second magnetic member 34 is powered on, and the heat generated by the second magnetic member 34 can heat the thermal deformation member 31, so that the thermal deformation member 31 can be switched to a liquid state. When the second magnetic member 34 is powered off, the second magnetic member 34 no longer applies a magnetic force to the first magnetic member 32, and the second magnetic member 34 no longer generates heat, so that the thermal deformation member 31 can be cooled and switched to a solid state.

[0036] For example, the first magnetic member 32 can be connected to the circumferential side of the bottom of the carrier 2, and the connecting plate 33 can be connected to the inner wall of the bottom of the base 1; or the first magnetic member 32 can be connected to the circumferential side of the middle of the carrier 2, and the connecting plate 33 can be connected to the inner wall of the middle of the base 1, so as to ensure that the first magnetic member 32 and the second magnetic member 34 can be kept close to each other, and the first magnetic member 32 can easily sense the magnetic field of the second magnetic member 34.

[0037] In the embodiment of the present application, when the second magnetic member 34 is powered on, the heat generated by the second magnetic member 34 can be transferred to the thermal deformation member 31, the thermal deformation member 31 can be converted to a liquid state by increasing the heating temperature, so that the first magnetic member 32 is released by the thermal deformation member 31. In this case, the first magnetic member 32 can generate movement after sensing the magnetic field force of the second magnetic member 34, and then drive the carrier 2 to move relative to the base 1. In this way, when performing a shooting task, the movement of the lens 6 can be realized, and at least one of the anti-shake function and the zoom function of the camera module can be realized.

[0038] When the second magnetic member 34 is powered off, the second magnetic member 34 no longer generates heat, so that the thermal deformation member 31 can be cooled and converted to a solid state. The thermal deformation member 31 can play a role of fastening, fastening the second magnetic member 34 and the connecting plate 33, so as to realize the fixation of the carrier 2 relative to the base 1. In this way, when the shooting task is not used, the lens 6 and the carrier 2 can also be locked, and the abnormal sound caused by the shaking of the lens 6 and the carrier 2 can be avoided.

[0039] In the embodiment of the present application, when the second magnetic member 34 is powered on, not only can the carrier 2 be driven to move, but also the thermal deformation member 31 can be switched to a liquid state by heating the thermal deformation member 31. The temperature adjusting member does not need to be separately arranged for the thermal deformation member 31, the structural complexity of the motor can be reduced, the manufacturing cost of the motor can be reduced, and the miniaturization design of the motor can be realized.

[0040] In the embodiment of the present application, the second magnetic member 34 can be powered on to realize at least one of the zoom function and the anti-shake function of the camera module when the shooting task is performed, and the second magnetic member 34 can be powered off so that the carrier 2 can be fixed relative to the base 1 when the shooting task is not performed, thereby improving the problem of abnormal noise caused by the shaking of the carrier 2.

[0042] In the embodiment of the present application, the movable part 323 moves in the containing space 35, so that the containing space 35 can limit the movement direction of the movable part 323, thereby playing a limiting and guiding role on the movement of the carrier 2, to ensure the reliability of the anti-shake function or the zoom function of the camera module.

[0043] Specifically, when the second magnetic member 34 is powered on, the thermal deformation member 31 is heated to melt into a liquid state, which can play a lubricating role, so that the magnetic part 322 can inductively drive the movable part 323 to smoothly move in the containing space 35; when the second magnetic member 34 is powered off, the thermal deformation member 31 can cool to solidify into a solid state, the thermal deformation member 31 can fix the movable part 323, increase the sliding friction of the movable part 323, thereby limiting the movement of the movable part 323, and the first magnetic member 32 can be fixed relative to the connecting plate 33, thereby improving the problem of abnormal noise caused by the shaking of the carrier 2.

[0044] Specifically, the movable part 323 and the containing space 35 cooperate to limit and guide the movement of the carrier 2, and by filling the thermal deformation member 31 in the containing space 35, the driving unit and the limiting unit can be integrated, so that the complexity of the motor is greatly reduced, and the size of the motor is conveniently reduced, wherein the driving unit is a unit for driving the carrier 2 to move relative to the base 1, and the limiting unit is a unit for limiting the movement of the carrier 2 in the non-shooting state.

[0045] Specifically, the movable part 323 and the magnetic part 322 can be fixedly connected or movably connected, etc. The magnetic part 322 can inductively generate a magnetic field to drive the movable part 323. The material of the magnetic part 322 can be iron, cobalt, nickel, alloy, etc., and the materials of the movable part 323 and the magnetic part 322 can be the same or different, etc.

[0046] In the embodiment of the present application, when the second magnetic member 34 is powered off, the thermal deformation member 31 can be hardened after transforming into a solid state, and can press the first magnetic member 32, so that the first magnetic member 32 is subjected to a larger friction force, thereby realizing that the carrier 2 is limited to move; when the second magnetic member 34 is powered on, the thermal deformation member 31 can be softened after transforming into a liquid state, so that the friction force acting on the first magnetic member 32 is reduced, and the thermal deformation member 31 in the liquid state can also play a lubricating role on the movable part 323, thereby improving the reliability of the first magnetic member 32 in inducting the magnetic field of the second magnetic member 34 and driving the carrier 2 to move relative to the base 1.

[0049] Specifically, when the second magnetic member 34 is powered on, the thermal deformation member 31 can be transformed into a liquid state by being heated by the second magnetic member 34, which can reduce the friction between the movable part 323 and the first groove 331 and the second groove 321, and facilitate the movement of the magnetic part 322 relative to the base 1; when the second magnetic member 34 is powered off, the thermal deformation member 31 can be transformed into a solid state by not being heated, which can increase the friction between the movable part 323 and the first groove 331 and the second groove 321, thereby limiting the movement of the carrier 2 relative to the base 1, and improving the problem of abnormal noise caused by the shaking of the carrier 2.

[0050] Specifically, the first groove 331 and the second groove 321 can be combined to form a complete track, which can play a guiding and limiting role on the movement of the movable part 323.

When the second magnetic part 34 is powered on, the magnetic part 322 can drive the movable part 323 to move in the first groove 331.

[0057] In the embodiments of the present application, at least part of the movable part 323 is embedded in the first groove 331, such that the first groove 331 can limit and guide the movable part 323. Thus, the movement of the carrier 2 can be limited and guided, to ensure the reliability of the anti-shake function or the zoom function of the camera module.

[0058] In the embodiment of the present application, when the second magnetic member 34 is powered on, the thermal deformation member 31 heated by the second magnetic member 34 can be converted to a liquid state, which can reduce the friction between the movable part 323 and the first groove 331, so as to facilitate the movement of the carrier 2 relative to the base 1 by the magnetic part 322; when the second magnetic member 34 is powered off, the thermal deformation member 31 can be converted to a solid state without being heated, which can increase the friction between the movable part 323 and the first groove 331, so as to limit the movement of the carrier 2 relative to the base 1, thereby improving the problem of abnormal noise caused by the shaking of the carrier 2.

[0067] In the embodiment of the application, the reinforcing member 37 is arranged on the groove wall of the first groove 331, which can enhance the structural strength of the groove wall of the first groove 331. Thus, when the movable part 323 moves in the first groove 331, the movable part 323 can be prevented from colliding with the connecting plate 33, so as to avoid the risk of generating debris or causing local deformation of the connecting plate 33, and ensure the functionality of the connecting plate 33.
