Description

Technical Field

[0001] The present application relates to the technical field of lens equipment, and in particular to a lens module and electronic equipment. Background Art

[0002] With the rapid development of smartphone camera technology, users have higher and higher requirements for camera performance, especially in terms of focus speed and image stability. Existing smartphone cameras are facing the problem of shaking and abnormal noise as the focus stroke increases and the mass of the mover increases. When users shake their phones, the large mass and long stroke of the mover often produce abnormal noises, which are mistaken for equipment abnormalities, affecting the user experience. The existing technology reduces the abnormal noise by adding cushioning materials such as soft glue, but the effect is not good and affects the movement of the mover during operation. Some technologies try to reduce shaking and abnormal noise by adding a power system to the motor to support the motor laterally. However, these solutions are often difficult to implement in practical applications due to magnetic interference and size issues of the motor, and the processing cost is very high. Summary of the invention

[0003] The present application provides a lens module and an electronic device, wherein the lens module is used to prevent a moving part from shaking and causing abnormal noise.

[0004] To achieve the above purpose, the embodiment of the present application adopts the following technical solution:

[0005] In a first aspect, a lens module is provided, which includes: a base; a movable part, on which an optical part is arranged, and the movable part is movably installed in the base; an energized deformation part, which is installed between the base and the movable part, and the energized deformation part has a limiting state that abuts against the movable part to limit the movement of the movable part, and a avoiding state that avoids the movable part, and when the energized deformation part is energized, the energized deformation part can be switched from the limiting state to the avoiding state, and when the energized deformation part is de-energized, the energized deformation part can be switched from the avoiding state to the limiting state.

[0006] The lens module provided in the embodiment of the present application can limit the movement of the movable part when necessary by switching the limiting state and the avoidance state of the energized deformation part, thereby reducing the abnormal noise caused by the movement of the movable part and improving the user's use and hearing experience. At the same time, when necessary, the restriction on the movable part is cancelled to avoid resistance to the movement of the movable part and ensure the driving stability of the movable part. By adjusting the energized state of the energized deformation part, the limiting and avoidance of the movable part can be quickly realized, and precise control can be achieved.

[0007] In one embodiment, the energized deformation part is mounted on the base, and a butt end is provided on the energized deformation part. When the energized deformation part is in a limited position, the butt end butts against the movable part, and when the energized deformation part is in an avoidance state, the butt end avoids the movable part. When the energized deformation part is in a limited position, the butt end will accurately butt against the movable part to limit its movement, thereby ensuring that the movable part is in a stable position; and when the energized deformation part is in an avoidance state, the butt end will avoid the movable part, allowing it to move freely to meet different adjustment requirements.

[0008] In one embodiment, a receiving cavity is provided inside the base, the movable part is movably installed in the receiving cavity, the electrified deformation part is installed on the first inner wall of the receiving cavity, and the abutment end is arranged toward the end or side of the movable part. The receiving cavity is provided inside the base, and the electrified deformation part is installed on the first inner wall of the receiving cavity, so as to improve the stable installation of the electrified deformation part, so that the electrified deformation part can be more closely combined with the movable part. The connectivity between the electrified deformation part and the movable part is enhanced, and the stability and reliability of the system are improved.

[0009] In one embodiment, the energized deformation portion includes an elastic telescopic structure, which is mounted on the first inner wall, and the abutment end is arranged at one end of the elastic telescopic structure close to the movable part, and when the energized deformation portion is in a limited state, the abutment end abuts against the end of the movable part. The energized deformation portion includes an elastic telescopic structure, and the elastic characteristics and elastic reset characteristics of the elastic telescopic structure are utilized to achieve avoidance of the movable part in the energized state and limitation of the movable part in the non-energized state.

[0010] In one embodiment, the elastic telescopic structure includes a first conductive structure and an energized compression spring connected to the first conductive structure. The first conductive structure is mounted on the first inner wall, and the abutting end is located at one end of the energized compression spring close to the mover portion. The first conductive structure is used to connect to an external power source and to electrically connect the energized compression spring. The energized compression spring is a main component for generating elastic force. The elastic properties and elastic reset properties of the elastic telescopic structure are used to achieve avoidance of the mover portion in the energized state and limit the mover portion in the non-energized state.

[0011] In one embodiment, the elastic telescopic structure further includes a second conductive structure, and there are at least two energized compression springs, and the second conductive structure is connected to one end of each energized compression spring close to the mover portion. The multiple energized compression springs together form a loop, providing a current transmission path for the energized deformation portion, thereby realizing the energization control of the elastic telescopic structure without the need to set up a separate wire to avoid circuit breakage during repeated expansion and contraction.

[0012] In one embodiment, a first insulating portion is provided at one end of the second conductive structure close to the mover portion. Direct contact between the second conductive structure and the mover portion is effectively isolated, and accidental current or interference caused by electrical contact is avoided, thereby ensuring stable operation of the lens module. By effectively isolating direct contact between the second conductive structure and the mover portion, the risk of system failure can be reduced, ensuring that the lens module can operate stably and reliably under various working conditions.

[0013] In one embodiment, the energized deformation part includes an elastic bending structure, the elastic bending structure is installed in the accommodating cavity, and the abutting end is arranged at the end of the elastic bending structure. When the energized deformation part is in a limited state, the abutting end abuts against the end or side of the mover part. Since the elastic bending structure has a smaller volume and weight, compared with other forms of energized deformation parts, it does not need to provide a compression space, and can better adapt to the use scenario of a smaller accommodating cavity, thereby further reducing the size of the entire lens module, making it more compact.

[0014] In one embodiment, the elastic bending structure includes a third conductive structure and an energized deformable spring sheet, the third conductive structure is mounted on the base, the energized deformable spring sheet is mounted on the end of the third conductive structure, and the abutment end is located at the end of the energized deformable spring sheet away from the third conductive structure. Through the third conductive structure, electricity can be effectively transmitted from the base to the energized deformable spring sheet to achieve control of the elastic bending structure. The above-mentioned power transmission mechanism ensures that the energized deformable part can accurately perform limiting or avoidance actions during operation, thereby ensuring the stability and reliability of the lens module. The third conductive structure extends along the gap between the side of the movable part and the base, supporting the elastic bending structure to a preset position, which can avoid space occupation.

[0015] In one embodiment, the elastic bending structure further includes a second insulating portion, which is disposed at one end of the energized deformable spring sheet away from the third conductive structure, and the second insulating portion forms an abutting end. The second insulating portion is disposed at one end of the energized deformable spring sheet away from the third conductive structure, effectively isolating the circuit of the energized deformable spring sheet from the mover portion. Even when the energized deformable portion is working, the current will not flow directly to the mover portion through the abutting end, thereby reducing the risk of circuit interference and short circuit.

[0016] In one embodiment, the elastic bending structure further includes a friction-increasing portion, which is arranged at one end of the energized deformable elastic sheet away from the third conductive structure, and the friction-increasing portion forms an abutting end, wherein the friction-increasing portion is made of an insulating material. The friction-increasing portion is a part of the energized deformable elastic sheet, and is located at one end thereof away from the third conductive structure. Since the friction-increasing portion is made of an insulating material and contacts the mover portion, it can provide additional friction. The increased friction can effectively stabilize the position of the mover portion and reduce its shaking and instability during movement.

[0017] In one embodiment, in the limited position state, the bending direction of the energized deformable spring piece is toward the side of the movable part. When the energized deformable part is in the limited position state, the energized deformable spring piece is in the initial state, bending toward the side of the movable part, and making the abutting end abut against the movable part, using friction to limit its movement, thereby ensuring that the movable part is in a stable position; and when the energized deformable part is in the avoidance state, the bending angle of the energized deformable spring piece is reduced, and the abutting end will avoid the side of the movable part, so that it can move freely to meet different adjustment requirements.

[0018] In one embodiment, in the limited position state, the bending direction of the energized deformable spring is toward the end of the movable part. When the energized deformable part is in the limited position state, the energized deformable spring is in the initial state, bends toward the end of the movable part, and makes the abutting end abut against the end of the movable part, and uses pressure to limit its movement, thereby ensuring that the movable part is in a stable position; and when the energized deformable part is in the avoidance state, the bending angle of the energized deformable spring is reduced, and the abutting end will avoid the end of the movable part, so that it can move freely to meet different adjustment requirements.

[0019] In one embodiment, the energized deformable spring includes two electrical connection sheets, and the third conductive structure includes two conductive sheets, which are respectively connected to the two electrical connection sheets. Each conductive sheet is respectively connected to an electrical connection sheet to form a loop. Since each conductive sheet is connected to an electrical connection sheet, the integrity of the circuit can be ensured.

[0020] In one embodiment, there are multiple energized deformable springs, the third conductive structure includes a conductive body and multiple conductive ends located at the edge of the conductive body, the conductive body is installed in the base, and the multiple energized deformable springs are installed on the multiple conductive ends one by one. Through the synergistic effect of the multiple energized deformable springs, the position and movement of the mover can be adjusted and controlled more accurately.

[0021] In one embodiment, a first electromagnetic driving part is disposed on the base, and a second electromagnetic driving part is disposed on the mover part, and the mover part is driven to move by the magnetic force between the first electromagnetic driving part and the second electromagnetic driving part.

[0022] A second aspect of the present application provides an electronic device, which includes a middle frame, a screen assembly installed on one side of the middle frame, a cover plate installed on the other side of the middle frame, and a lens module installed on the middle frame, wherein a lens clearance hole is provided on the cover plate, and the position of the lens clearance hole corresponds to the position of the lens module, and the lens module is the above-mentioned lens module, wherein the electronic device also includes an image sensing part installed on the middle frame, the image sensing part is located at one end of the lens module, and light can pass through the optical part to reach the image sensing part.

[0023] Through the above technical solution, since the electronic device includes the above lens module, it at least has all the beneficial effects of the lens module, which will not be repeated here. BRIEF DESCRIPTION OF THE DRAWINGS

[0064] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0065] Smartphone cameras in related technologies face the problem of shaking and abnormal noise as the focus stroke increases and the mass of the mover increases. When the user shakes the phone, the large mass and long stroke of the mover often produce abnormal noises, which will be mistaken for equipment abnormalities, thus affecting the user experience. The existing technology reduces the abnormal noise by adding cushioning materials such as soft glue, but the effect is not good and affects the movement of the mover during operation. Some technologies attempt to reduce shaking and abnormal noise by adding a power system to the motor to support the motor laterally. However, these solutions are often difficult to implement in practical applications due to magnetic interference and size issues of the motor, and the processing cost is very high.

[0066] Specifically, please refer to Figures 1 to 5 and Figures 8 to 15As shown, the lens module of the embodiment of the present application includes a base 10, a movable part 20 and an electrified deformation part 30, the movable part 20 is provided with an optical part 21, and the movable part 20 is movably installed in the base 10; the electrified deformation part 30 is installed between the base 10 and the movable part 20, and the electrified deformation part 30 has a limiting state of abutting against the movable part 20 to limit the movement of the movable part 20, and a avoiding state of avoiding the movable part 20, and when the electrified deformation part 30 is electrified, the electrified deformation part 30 can be switched from the limiting state to the avoiding state, and when the electrified deformation part 30 is de-energized, the electrified deformation part 30 can be switched from the avoiding state to the limiting state. The moving direction of the movable part 20 is the optical axis direction of the lens module, that is, the optical axis toward the photosensitive image sensor, wherein the energized deformation part 30 adopts SMA (Shape Memory Alloy), and the SMA material has a shape memory effect, that is, within a certain temperature range, it can restore its preset shape. Therefore, the SMA material is suitable for the energized deformation part 30, because it can change its shape when it is energized, and then restore it to its original state when it is powered off, so as to limit the position and contact of the movable part 20. At the same time, the SMA material has a high degree of elasticity and plasticity, and can withstand large deformation without losing its original shape. The energized deformation part 30 can withstand certain stress and deformation during operation without causing damage or failure of the material. The response speed of the SMA material is relatively fast, and it can quickly change its shape after the current is applied or removed. The fast response speed helps to achieve fast and accurate adjustment of the position of the movable part 20. At the same time, the corrosion resistance and wear resistance of the energized deformation part 30 can be guaranteed by the SMA material, which is suitable for lightweight and miniaturized application scenarios, such as smartphone camera modules. By switching the limit state and the avoidance state of the energized deformation part 30, the movement of the movable part 20 can be limited when necessary, thereby reducing the abnormal noise caused by the movement of the movable part 20 and improving the user's use and auditory experience. At the same time, when necessary, the restriction on the movable part 20 is cancelled to avoid resistance to the movement of the movable part 20 and ensure the driving stability of the movable part 20. By adjusting the energized state of the energized deformation part 30, the limit and avoidance of the movable part 20 can be quickly realized to achieve precise control. Compared with the practice of adding a power system to the motor in the traditional solution, the embodiment of the present application is more concise and avoids the influence that may be caused by the magnetic interference of the motor. Ensure the stability and reliability of the camera system, while reducing the interference with other components of the system and improving the overall performance. Since the energized deformation part 30 can adopt a simple structural design and does not require a complex motor system, it can reduce the manufacturing cost and improve the production efficiency. For the scenario of mass production of smartphone camera modules, it can reduce the manufacturing cost of the product and enhance the market competitiveness.

[0067] It should be noted that the above-mentioned lens module refers to a component, which usually includes a lens, an optical part 21, a power drive component, etc., and is a modular component for realizing imaging functions in electronic devices (such as smart phones, cameras, etc.). The movable part 20 refers to the movable part in the lens module, which is usually used to adjust the focal length, focus or optical stabilization and other functions. The optical part 21 refers to the optical elements in the lens module, such as lenses, prisms, filters, etc., which are used to focus or process light to realize imaging functions. The abutment end refers to one end or component of the energized deformation part 30, which is used to abut or contact the movable part 20, limit its movement in the limited state, or avoid the movable part 20 in the avoidance state.

[0068] For example, in the application scenario of a mobile phone, when the power is turned off or the camera is not enabled, the lens module is not powered on. At this time, the powered deformation part 30 is not powered on and the limiting state is used to abut against the movable part 20 to limit the movement of the movable part 20, thereby effectively avoiding abnormal noise when the power is turned off or the camera is not enabled. When the power is turned on or the camera is enabled, the lens module is powered on. At this time, the powered deformation part 30 is powered on and the avoiding state is used to avoid the movable part 20, so that the driving component can drive the movement of the movable part 20 to achieve focusing or zooming and other actions.

[0069] The energized deformation part 30 is installed between the base 10 and the movable part 20, which means that the energized deformation part 30 can be installed on the base 10 and abut against the movable part 20 to limit the movable part 20, or can be installed on the movable part 20 and abut against the base 10 to limit the movable part 20. Figures 2 to 5 , Figures 10 to 15 As shown, in order to facilitate the layout of the circuit and the stability of the circuit, and to prevent the movement of the movable part from affecting the circuit operation, the energized deformation part 30 of the embodiment of the present application is installed on the base 10, and the energized deformation part 30 is provided with abutting end. When the energized deformation part 30 is in the limiting state, the abutting end abuts against the movable part 20, and when the energized deformation part 30 is in the avoiding state, the abutting end avoids the movable part 20. When the energized deformation part 30 is in the limiting state, the abutting end will accurately abut against the movable part 20, restricting its movement, thereby ensuring that the movable part 20 is in a stable position; and when the energized deformation part 30 is in the avoiding state, the abutting end will avoid the movable part 20, so that it can move freely to meet different adjustment requirements.

[0070] See also Figures 2 to 5 , Figures 10 to 15As shown, the base 10 of the embodiment of the present application is provided with a receiving chamber 11 inside, the mover part 20 is movably installed in the receiving chamber 11, the electrified deformation part is installed on the first inner wall of the receiving chamber 11, and the abutment end is arranged toward the end or side of the mover part 20. The receiving chamber 11 is arranged in the base 10, and the electrified deformation part 30 is installed on the first inner wall of the receiving chamber 11, so as to improve the stable installation of the electrified deformation part 30, so that the electrified deformation part 30 can be more closely combined with the mover part 20. The connectivity between the electrified deformation part 30 and the mover part 20 is enhanced, and the stability and reliability of the system are improved. The abutment end is arranged to face the end of the mover part 20, so that the abutment end is directly in contact with the end of the mover part 20. This arrangement is used in the scene where the space of the receiving chamber 11 is relatively sufficient, so as to realize the precise limit of the position of the mover part 20 and ensure that the mover part 20 is stable and immobile at a specific position. The abutting end is arranged to face the side of the mover part 20, so that the abutting end directly contacts the side of the mover part 20. This arrangement is used in the scenario where the space of the accommodating cavity 11 is relatively small, and the position of the mover part 20 is precisely limited.

[0071] See also Figures 2 to 7 As shown, the energized deformation part 30 of the embodiment of the present application includes an elastic telescopic structure 31, which is installed on the first inner wall, and the abutting end is arranged at one end of the elastic telescopic structure 31 close to the movable part 20. When the energized deformation part 30 is in a limited state, the abutting end abuts against the end of the movable part 20. The energized deformation part 30 includes the elastic telescopic structure 31, and the elastic resetting characteristics of the elastic telescopic structure 31 are utilized to achieve the avoidance of the movable part 20 in the energized state and the limiting of the movable part 20 in the non-energized state. In the energized state, the elastic telescopic structure 31 will overcome the elastic retraction, so that the abutting end can avoid the movable part 20; while in the de-energized state, the elastic telescopic structure 31 will restore its original state through elastic force, so that the abutting end can abut against the movable part 20 to achieve limiting.

[0072] See also Figures 2 to 7As shown, the elastic telescopic structure 31 of the embodiment of the present application includes a first conductive structure 311 and a powered compression spring 312 connected to the first conductive structure 311. The first conductive structure 311 is installed on the first inner wall, and the abutment end is located at one end of the powered compression spring 312 close to the movable part 20. The first conductive structure 311 is used to connect to an external power source and to electrically connect the powered compression spring 312. The powered compression spring 312 is the main component for generating elastic force. The elastic properties and elastic reset properties of the elastic telescopic structure 31 are utilized to achieve avoidance of the movable part 20 in the powered state and limitation of the movable part 20 in the non-powered state. The compression deformation of the powered compression spring 312 will generate elastic force, and the abutment force on the movable part 20 can be increased by setting the length of the powered compression spring 312. In the limited state, this additional abutment force can make the connection between the movable part 20 and the abutment end tighter, thereby increasing the stability and reliability of the system. See. Figure 2 As shown, in one embodiment of the present application, a receiving space is provided at the first inner wall, and when powered on, the elastic telescopic structure 31 retracts into the receiving space.

[0073] See also Figures 2 to 7 As shown, the elastic telescopic structure 31 of the embodiment of the present application also includes a second conductive structure 313, and there are at least two energized compression springs 312, and the second conductive structure 313 is connected to one end of each energized compression spring 312 close to the mover part 20. A plurality of energized compression springs 312 together form a loop, providing a current transmission path for the energized deformation part 30, thereby realizing the energization control of the elastic telescopic structure 31, without the need to set up wires separately, to avoid circuit breakage during repeated telescopic operation. By using a plurality of energized compression springs 312 to form a loop together, the use of additional wires or connectors can be avoided, thereby simplifying the electrical connection design of the lens module. Not only does it reduce the complexity of the circuit connection, but it also reduces the cost and maintenance difficulty of the system. The use of a plurality of energized compression springs 312 can significantly increase the stability of the system. Since each energized compression spring 312 can provide additional support and stability, the entire elastic telescopic structure 31 can be more evenly stressed during operation. For example, there are two second conductive structures 313 and two energized compression springs 312, one of which is a forward path and the other is a reverse path.

[0074] See also Figures 2 to 7As shown, a first insulating portion 3131 is provided at one end of the second conductive structure 313 of the embodiment of the present application close to the mover portion 20. Prevent electrical short circuit or interference between the conductive structure and the mover portion 20. The first insulating portion 3131 effectively isolates the direct contact between the second conductive structure 313 and the mover portion 20, avoiding accidental current or interference caused by electrical contact, thereby ensuring the stable operation of the lens module. By effectively isolating the direct contact between the second conductive structure 313 and the mover portion 20, the risk of system failure can be reduced, ensuring that the lens module can operate stably and reliably under various working conditions. Among them, the first insulating portion 3131 can be made of polymer materials: such as polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polytetrafluoroethylene (PTFE), etc. These polymer materials have excellent insulation properties, wear resistance and corrosion resistance, and are easy to process into various shapes, so they are often used in insulating components in electronic equipment. Rubber materials: such as silicone, nitrile rubber (NBR), propylene rubber (ACM), etc. Rubber materials have good elasticity and wear resistance, as well as good insulation properties, and are suitable for applications that require soft sealing and insulation. Resin materials: such as epoxy resin, polyamide resin (PA), phenolic resin, etc. These resin materials have excellent insulation properties, high temperature resistance and chemical resistance, and are suitable for insulation requirements under high temperature, high pressure or special environments.

[0075] See also Figures 8 to 15 As shown, the energized deformation part 30 adopting the elastic compression structure is suitable for the scene where the space of the accommodating cavity 11 is relatively sufficient. In some scene embodiments where the accommodating cavity 11 is small, the energized deformation part 30 of the embodiment of the present application includes an elastic bending structure 32, and the elastic bending structure 32 is installed in the accommodating cavity 11. The abutment end is arranged at the end of the elastic bending structure 32. When the energized deformation part 30 is in a limited state, the abutment end abuts against the end or side of the mover part 20. The elastic bending structure 32 is installed in the accommodating cavity 11, which utilizes the limited space of the accommodating cavity 11 and effectively saves the overall volume of the system. Since the elastic bending structure 32 has a smaller volume and weight, compared with other forms of energized deformation parts 30, it does not need to provide compression space, and can better adapt to the use scenario of a smaller accommodating cavity 11, thereby further reducing the size of the entire lens module and making it more compact.

[0076] See also Figures 10 to 15As shown, the elastic bending structure 32 of the embodiment of the present application includes a third conductive structure 321 and an energized deformable elastic sheet 322. The third conductive structure 321 is mounted on the base 10, and the energized deformable elastic sheet 322 is mounted at the end of the third conductive structure 321, and the abutting end is located at the end of the energized deformable elastic sheet 322 away from the third conductive structure 321. The third conductive structure 321 not only plays the role of supporting the energized deformable elastic sheet 322, but also is responsible for transmitting power to the energized deformable elastic sheet 322. Through the third conductive structure 321, power can be effectively transmitted from the base 10 to the energized deformable elastic sheet 322 to achieve control of the elastic bending structure 32. The above-mentioned power transmission mechanism ensures that the energized deformable part 30 can accurately perform the limiting or avoidance action when working, thereby ensuring the stability and reliability of the lens module. The third conductive structure 321 extends along the gap between the side of the movable part 20 and the base 10, and supports the elastic bending structure 32 to a preset position, which can avoid space occupation. The side transmission of the third conductive structure 321 improves the adaptability and flexibility of the lens module.

[0077] See also Fig.16 , Fig.17 , Fig.19 and Fig. 20 As shown, the elastic bending structure 32 of the embodiment of the present application also includes a second insulating portion 323, which is arranged at one end of the energized deformed elastic piece 322 away from the third conductive structure 321, and the second insulating portion 323 forms a butt end. The second insulating portion 323 is arranged at one end of the energized deformed elastic piece 322 away from the third conductive structure 321, effectively isolating the circuit of the energized deformed elastic piece 322 and the mover part 20. Even when the energized deformed part 30 is working, the current will not flow directly to the mover part 20 through the butt end, thereby reducing the risk of circuit interference and short circuit. Through this electrical isolation, the safety of the lens module is greatly improved, ensuring the stability of the system and the safety of the user. When the energized deformed part 30 is working, the butt end interacts with the mover part 20 to achieve precise control of the position of the mover part 20. The second insulating portion 323 can be made of polymer materials: for example, polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polytetrafluoroethylene (PTFE), etc. These polymer materials have excellent insulation properties, wear resistance and corrosion resistance, and are easy to process into various shapes, so they are often used in insulating components in electronic equipment. Rubber materials: such as silicone, nitrile rubber (NBR), propylene rubber (ACM), etc. Rubber materials have good elasticity and wear resistance, as well as good insulation properties, and are suitable for some applications that require soft sealing and insulation. Resin materials: such as epoxy resin, polyamide resin (PA), phenolic resin, etc. These resin materials have excellent insulation properties, high temperature resistance and chemical resistance, and are suitable for insulation requirements under high temperature, high pressure or special environments.

[0078] See also Fig.18 and Fig.21 As shown, the elastic bending structure 32 of the embodiment of the present application also includes a friction-increasing portion 324, which is arranged at one end of the energized deformed elastic piece 322 away from the third conductive structure 321, and the friction-increasing portion 324 forms abutting end, wherein the friction-increasing portion 324 is made of an insulating material. The friction-increasing portion 324 is a part of the energized deformed elastic piece 322, and is located at one end thereof away from the third conductive structure 321. Since the friction-increasing portion 324 is made of an insulating material and contacts with the mover portion 20, it can provide additional friction. The increased friction can effectively stabilize the position of the mover portion 20 and reduce its shaking and instability during movement. The friction-increasing portion 324 is made of an insulating material, which effectively prevents current from flowing to the mover portion 20, thereby reducing the risk of circuit interference and short circuit. Among them, the friction-increasing portion 324 can be made of polyimide (PI): polyimide has excellent insulation properties, high temperature resistance and chemical corrosion resistance, and is suitable for use in high temperature environments and harsh conditions. Polytetrafluoroethylene (PTFE): PTFE has excellent insulation properties, chemical stability and wear resistance, and can remain stable in various environments. Polyetherketone (PEEK): PEEK has excellent insulation properties, wear resistance and chemical corrosion resistance, and is suitable for applications requiring high strength and durability. Polyurethane (PU): Polyurethane has good insulation properties and wear resistance, as well as high elasticity and flexibility, and is suitable for parts that need to be bent or flexed. Fluororubber (FKM): FKM has excellent oil resistance, corrosion resistance and wear resistance, and is suitable for insulating parts in some special environments.

[0079] The existence of the friction increasing part 324 and the second insulating part 323 can prevent the energized deformation structure from directly rubbing against the mover part 20, thereby avoiding damage to the mover part 20 and preventing dust from being generated by friction, thereby affecting the imaging and adjustment actions of the lens module.

[0080] See also Fig.10 , Fig.11 and Figures 14 to 18 As shown, in one embodiment, in the limited position state of the embodiment of the present application, the bending direction of the energized deformable spring piece 322 is toward the side of the movable part 20. When the energized deformable part 30 is in the limited position state, the energized deformable spring piece 322 is in the initial state, bending toward the side of the movable part 20, and the abutting end abuts against the movable part 20, and the movement is limited by friction, thereby ensuring that the movable part 20 is in a stable position; and when the energized deformable part 30 is in the avoidance state, the bending angle of the energized deformable spring piece 322 is reduced, and the abutting end avoids the side of the movable part 20, so that it can move freely to meet different adjustment requirements.

[0081] See also Figure 12 to Figure 14 and Figures 19 to 21As shown, in the limiting state of the embodiment of the present application, the bending direction of the energized deformable spring 322 is toward the end of the movable part 20. When the energized deformable part 30 is in the limiting state, the energized deformable spring 322 is in the initial state, bending toward the end of the movable part 20, and making the abutting end abut against the end of the movable part 20, using pressure to limit its movement, thereby ensuring that the movable part 20 is in a stable position; and when the energized deformable part 30 is in the avoidance state, the bending angle of the energized deformable spring 322 is reduced, and the abutting end will avoid the end of the movable part 20, so that it can move freely and adapt to different adjustment requirements. The difference is that when the energized deformable part 30 in this embodiment is in the avoidance position, there is a preset distance between the abutting end and the end of the movable part 20 to provide sufficient space for the movement of the movable part 20.

[0082] See also Figures 10 to 21 As shown, the energized deformable spring 322 of the embodiment of the present application includes two electrical connection sheets 3221, and the third conductive structure 321 includes two conductive sheets 3211, and the two conductive sheets 3211 are respectively connected to the two electrical connection sheets 3221. Each conductive sheet 3211 is respectively connected to an electrical connection sheet 3221 to form a loop. Since each conductive sheet 3211 is connected to an electrical connection sheet 3221, the integrity of the circuit can be ensured.

[0083] See also Fig.14 and Fig.15 As shown, there are multiple energized deformable springs 322 in the embodiment of the present application, and the third conductive structure 321 includes a conductive body and multiple conductive ends located at the edge of the conductive body. The conductive body is installed in the base 10, and multiple energized deformable springs 322 are installed on the multiple conductive ends one by one. The ability to control the position of the movable part 20 is enhanced. Through the synergistic effect of multiple energized deformable springs 322, the position and movement of the movable part 20 can be adjusted and controlled more accurately. It ensures that the current can be transmitted smoothly and maintains a stable connection state. Even if one of the energized deformable springs 322 has a problem, the other energized deformable springs 322 can still continue to work and will not affect the operation of the entire system. Integrating multiple conductive ends on a conductive body is convenient for installation and transportation of parts.

The first electromagnetic drive unit and the second electromagnetic drive unit are components composed of an electromagnetic coil and a magnetic material, respectively. When current passes through the electromagnetic coil, a magnetic field is generated, which interacts with the magnetic material in the second electromagnetic drive unit to generate a magnetic force. This magnetic force is used to drive the movement of the mover unit 20 to achieve functions such as focusing, zooming or image stabilization.
