Description

Technical Field

[0001] This application relates to the field of lens equipment technology, and in particular to a lens module and electronic device. Background Technology

[0002] With the rapid development of smartphone camera technology, users have increasingly higher performance requirements for cameras, especially in terms of focusing speed and image stability. Existing smartphone cameras, with their increasing focusing stroke and moving part mass, face the problem of rattling noise. When users shake their phones, the large mass and long stroke of the moving part often produce noise, which can be mistaken for a device malfunction, thus affecting the user experience. Existing technologies use cushioning materials such as soft rubber to reduce noise, but the effect is unsatisfactory and affects the movement of the moving part during operation. Some technologies attempt to reduce rattling noise by adding a power system to the motor to laterally hold it in place. However, these solutions are often difficult to implement in practical applications due to magnetic interference and size issues with the motor, and the manufacturing costs are high. Summary of the Invention

[0003] This application provides a lens module and an electronic device, the lens module being used to prevent abnormal noise caused by shaking of the moving part.

[0004] To achieve the above objectives, the embodiments of this application adopt the following technical solutions:

[0005] In a first aspect, a lens module is provided, comprising: a base; a movable part having an optical part disposed thereon, the movable part being movably mounted within the base; and an electrically conductive deformable part mounted between the base and the movable part, the electrically conductive deformable part having a limiting state that abuts against the movable part to restrict the movement of the movable part, and a repelling state that avoids the movable part, wherein energizing the electrically conductive deformable part enables it to switch from the limiting state to the repelling state, and de-energizing the electrically conductive deformable part enables it to switch from the repelling state to the limiting state.

[0006] The lens module provided in this application embodiment can restrict the movement of the moving part when necessary by switching between the limiting state and the avoidance state of the energized deformation part, thereby reducing abnormal noise caused by the movement of the moving part and improving the user's experience and auditory perception. Simultaneously, it can remove the restriction on the moving part when necessary, avoiding resistance to the movement of the moving part and ensuring the driving stability of the moving part. By adjusting the energization state of the energized deformation part, the limiting and avoidance of the moving part can be quickly achieved, enabling precise control.

[0007] In one embodiment, the energized deformable part is mounted on a base and has a stop end. When the energized deformable part is in a limited position, the stop end abuts against the moving part; when the energized deformable part is in a clearance position, the stop end clearances the moving part. When the energized deformable part is in a limited position, the stop end accurately abuts against the moving part, restricting its movement and ensuring that the moving part is in a stable position. When the energized deformable part is in a clearance position, the stop end clearances the moving part, allowing it to move freely to adapt to different adjustment needs.

[0008] In one embodiment, a receiving cavity is provided inside the base, and the moving part is movably installed within the receiving cavity. An energized deformation part is installed on the first inner wall of the receiving cavity, with its abutting end facing the end or side of the moving part. Providing a receiving cavity within the base and installing the energized deformation part on the first inner wall of the receiving cavity improves the stability of the energized deformation part, allowing it to be more tightly coupled with the moving part. This enhances the connection between the energized deformation part and the moving part, improving the stability and reliability of the system.

[0009] In one embodiment, the energized deformable part includes an elastic telescopic structure mounted on the first inner wall. An abutment end is disposed at the end of the elastic telescopic structure near the moving part. When the energized deformable part is in a limited position, the abutment end abuts against the end of the moving part. The energized deformable part includes an elastic telescopic structure, utilizing the telescopic and elastic reset characteristics of the structure to achieve avoidance of the moving part in the energized state and limitation of the moving 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 a first inner wall, with its abutting end located at the end of the energized compression spring near the moving part. The first conductive structure is used to connect to an external power source to electrically connect the energized compression spring, which is the main component for generating elastic force. Utilizing the telescopic and elastic restoring characteristics of the elastic telescopic structure, it achieves avoidance of the moving part in the energized state and limitation of the moving part in the non-energized state.

[0011] In one embodiment, the elastic telescopic structure further includes a second conductive structure. At least two energized compression springs are present, and the second conductive structure is connected to the end of each energized compression spring closest to the moving part. Multiple energized compression springs together form a circuit, providing a current transmission path for the energized deformation part, thereby achieving energization control of the elastic telescopic structure without the need for separate wiring, avoiding circuit breakage during repeated expansion and contraction.

[0012] In one embodiment, a first insulating portion is provided at the end of the second conductive structure near the moving part. This effectively isolates the direct contact between the second conductive structure and the moving part, avoiding unexpected currents 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 and the moving part, the risk of system failure can be reduced, ensuring that the lens module can operate stably and reliably under various operating conditions.

[0013] In one embodiment, the energized deformation portion includes an elastic bending structure, which is installed within the receiving cavity. An abutment end is disposed at the end of the elastic bending structure. When the energized deformation portion is in a limited position, the abutment end abuts against the end or side of the moving part. Because the elastic bending structure has a smaller volume and weight, compared to other forms of energized deformation portions, it does not require compression space, making it better suited for applications with smaller receiving cavities. This further reduces the overall size of the lens module, making it more compact.

[0014] In one embodiment, the elastic bending structure includes a third conductive structure and an energized deformation spring. The third conductive structure is mounted on a base, and the energized deformation spring is mounted at one end of the third conductive structure, with the abutment end located at the end of the energized deformation spring furthest from the third conductive structure. Through the third conductive structure, electricity can be effectively transmitted from the base to the energized deformation spring, enabling control of the elastic bending structure. This power transmission mechanism ensures that the energized deformation part can accurately perform limiting or avoidance actions during operation, thereby guaranteeing the stability and reliability of the lens module. The third conductive structure extends along the gap between the side of the moving part and the base, supporting the elastic bending structure in a preset position, thus avoiding space occupation.

[0015] In one embodiment, the elastic bending structure further includes a second insulating portion disposed at the end of the energized deformable spring away from the third conductive structure, forming a contact end. The second insulating portion, located at the end of the energized deformable spring away from the third conductive structure, effectively isolates the circuit between the energized deformable spring and the moving part. Even when the energized deformable part is operating, current will not flow directly to the moving part through the contact end, thereby reducing the risk of circuit interference and short circuits.

[0016] In one embodiment, the elastic bending structure further includes a friction-enhancing portion disposed at the end of the energized deformable spring away from the third conductive structure, forming an abutment end. The friction-enhancing portion is made of an insulating material. The friction-enhancing portion is part of the energized deformable spring and located at its end away from the third conductive structure. Because the friction-enhancing portion is made of an insulating material and contacts the moving part, it provides additional friction. The increased friction effectively stabilizes the position of the moving part, reducing its swaying and instability during movement.

[0017] In one embodiment, in the limited state, the bending direction of the energized deformation spring is towards the side of the moving part. When the energized deformation part is in the limited state, the energized deformation spring is in its initial state, bending towards the side of the moving part, and the abutting end abuts against the moving part, using friction to restrict its movement, thereby ensuring that the moving part is in a stable position; while when the energized deformation part is in the avoidance state, the bending angle of the energized deformation spring decreases, and the abutting end avoids the side of the moving part, allowing it to move freely to adapt to different adjustment needs.

[0018] In one embodiment, in the limited position, the bending direction of the energized deformation spring is towards the end of the moving part. When the energized deformation part is in the limited position, the energized deformation spring is in its initial state, bending towards the end of the moving part, and the abutment end abuts against the end of the moving part, using pressure to restrict its movement, thereby ensuring that the moving part is in a stable position; while when the energized deformation part is in the avoidance state, the bending angle of the energized deformation spring decreases, and the abutment end avoids the end of the moving part, allowing it to move freely to adapt to different adjustment needs.

[0019] In one embodiment, the energized deformable spring includes two electrical connecting pieces, and the third conductive structure includes two conductive pieces, each connected to one of the two electrical connecting pieces. Each conductive piece is connected to one electrical connecting piece, forming a circuit. Because each conductive piece is connected to one electrical connecting piece, the integrity of the circuit can be ensured.

[0020] In one embodiment, there are multiple energized deformable springs, and 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 a base, and the multiple energized deformable springs are installed one-to-one on the multiple conductive ends. Through the synergistic effect of the multiple energized deformable springs, the position and movement of the moving part can be adjusted and controlled more precisely.

[0021] In one embodiment, a first electromagnetic drive unit is provided on the base, and a second electromagnetic drive unit is provided on the mover unit. The mover unit is moved by the magnetic force between the first electromagnetic drive unit and the second electromagnetic drive unit.

[0022] The second aspect of this application provides an electronic device, which includes a mid-frame, a screen assembly mounted on one side of the mid-frame, a cover plate mounted on the other side of the mid-frame, and a lens module mounted on the mid-frame. The cover plate is provided with a lens clearance hole, the position of which corresponds to the position of the lens module. The lens module is the aforementioned lens module. The electronic device also includes an image sensing unit mounted on the mid-frame, the image sensing unit being located at one end of the lens module, and light can pass through the optical unit to reach the image sensing unit.

[0023] With the above technical solution, since the electronic device includes the above lens module, it has at least all the beneficial effects of the lens module, which will not be elaborated here. Attached Figure Description

Specifically, the use of the words "in one embodiment," "exemplarily," and "for example" is intended to present the relevant concepts in a specific manner.

[0064] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments.

[0065] With the increasing focusing stroke and moving part mass in smartphone cameras, the issue of vibration-induced noise arises. When users shake their phones, the large mass and long stroke of the moving part often produce noise, which can be mistaken for device malfunction, thus affecting the user experience. Existing technologies use cushioning materials such as soft rubber to reduce noise, but the effect is unsatisfactory and hinders the movement of the moving part during operation. Some technologies attempt to reduce vibration-induced noise by adding a power system to the motor to laterally support it. However, these solutions are often difficult to implement in practice due to magnetic interference and size issues with the motor, and the manufacturing costs are high.

[0066] Specifically, please refer to Figures 1 to 5 and Figures 8 to 15As shown, the lens module of this application embodiment includes a base 10, a moving part 20, and an electrically conductive deformation part 30. An optical part 21 is provided on the moving part 20, and the moving part 20 is movably installed in the base 10. The electrically conductive deformation part 30 is installed between the base 10 and the moving part 20. The electrically conductive deformation part 30 has a limiting state that abuts against the moving part 20 to restrict the movement of the moving part 20, and a yielding state that avoids the moving part 20. When the electrically conductive deformation part 30 is energized, it can switch from the limiting state to the yielding state. When the electrically conductive deformation part 30 is de-energized, it can switch from the yielding state to the limiting state. The moving part 20 moves in the direction of the optical axis of the lens module, i.e., towards the optical axis of the photosensitive image sensor. The electrically deformable part 30 uses SMA (Shape Memory Alloy). SMA material has a shape memory effect, meaning it can recover its preset shape within a certain temperature range. This makes SMA material suitable for the electrically deformable part 30, as it can change shape when energized and then return to its original shape when de-energized, thus restricting the position and contact of the moving part 20. Simultaneously, SMA material has high elasticity and plasticity, capable of withstanding large deformations without losing its original shape. The electrically deformable part 30 can withstand certain stress and deformation during operation without material damage or failure. SMA material has a relatively fast response speed, rapidly changing shape after current is applied or removed. This fast response speed facilitates quick and accurate adjustment of the moving part 20's position. Furthermore, SMA material ensures the corrosion resistance and wear resistance of the electrically deformable part 30, making it suitable for lightweight and miniaturized applications, such as smartphone camera modules. By switching between the limiting and avoidance states of the energized deformation section 30, the movement of the moving part 20 can be restricted when necessary, thereby reducing abnormal noise caused by the movement of the moving part 20 and improving the user's experience and auditory perception. Simultaneously, the restriction on the moving part 20 can be lifted when necessary, avoiding resistance to its movement and ensuring the driving stability of the moving part 20. By adjusting the energizing state of the energized deformation section 30, the limiting and avoidance of the moving part 20 can be quickly achieved, enabling precise control. Compared to the traditional approach of adding a power system to the motor, the embodiment of this application is simpler and avoids the potential impact of motor magnetic interference. This ensures the stability and reliability of the camera system while reducing interference to other components, improving overall performance. Since the energized deformation section 30 can adopt a simple structural design and does not require a complex motor system, manufacturing costs can be reduced and production efficiency improved. For scenarios involving large-scale production of smartphone camera modules, this can reduce product manufacturing costs and enhance market competitiveness.

[0067] It should be noted that the aforementioned lens module refers to a component, typically including a lens, optical part 21, and power drive components, etc., used in electronic devices (such as smartphones, cameras, etc.) to realize imaging functions. The movable part 20 refers to the movable component in the lens module, typically used for functions such as adjusting focus, focusing, or optical stabilization. The optical part 21 refers to the optical elements in the lens module, such as lenses, prisms, and filters, used for focusing or processing light to achieve imaging functions. The abutting end refers to one end or component of the energized deformation part 30, used to abut or contact the movable part 20, restricting its movement in a limited state, or avoiding the movable part 20 in an avoidance state.

[0068] For example, in mobile phone applications, when the phone is powered off or the camera is not enabled, the lens module is not powered on. At this time, the energized deformation part 30 is in a limiting state when it is not powered on, and it abuts against the moving part 20 to restrict the movement of the moving part 20. This effectively avoids abnormal noise when the phone is powered off or the camera is not enabled. When the phone is powered on or the camera is enabled, the lens module is powered on. At this time, the energized deformation part 30 is in a yielding state when it is powered on, and it avoids the moving part 20, so that the drive component can drive the moving part 20 to move and achieve focusing or zooming.

[0069] The energized deformation part 30 is installed between the base 10 and the moving part 20. This means that the energized deformation part 30 can be installed on the base 10, abutting against the moving part 20 to limit the movement of the moving part 20, or it can be installed on the moving part 20, abutting against the base 10 to limit the movement of the moving part 20. See also Figures 2 to 5 , Figures 10 to 15 As shown, to facilitate circuit layout and ensure circuit stability, and to prevent the movement of the moving part from affecting circuit operation, the energized deformable part 30 of this embodiment is mounted on the base 10. The energized deformable part 30 has a stop end. When the energized deformable part 30 is in a limited position, the stop end abuts against the moving part 20. When the energized deformable part 30 is in a clearance position, the stop end clears the moving part 20. When the energized deformable part 30 is in a limited position, the stop end accurately abuts against the moving part 20, restricting its movement and ensuring that the moving part 20 is in a stable position. When the energized deformable part 30 is in a clearance position, the stop end clears the moving part 20, allowing it to move freely to adapt to different adjustment needs.

[0070] See Figures 2 to 5 , Figures 10 to 15As shown, the base 10 of this embodiment has a receiving cavity 11 inside, and the moving part 20 is movably installed in the receiving cavity 11. The energized deformation part is installed on the first inner wall of the receiving cavity 11, with its abutting end facing the end or side of the moving part 20. The receiving cavity 11 is provided inside the base 10, and the energized deformation part 30 is installed on the first inner wall of the receiving cavity 11 to improve the stability of the energized deformation part 30, allowing it to be more tightly connected to the moving part 20. This enhances the connection between the energized deformation part 30 and the moving part 20, improving the stability and reliability of the system. The abutting end is positioned facing the end of the moving part 20, so that the abutting end directly contacts the end of the moving part 20. This arrangement is suitable for scenarios where the space in the receiving cavity 11 is relatively sufficient, achieving precise positioning of the moving part 20 and ensuring that the moving part 20 remains stable in a specific position. The abutment end is positioned so that it faces the side of the moving part 20, allowing it to directly contact the side of the moving part 20. This configuration is suitable for scenarios where the cavity 11 has a relatively small space, enabling precise positioning of the moving part 20.

[0071] See Figures 2 to 7 As shown, the energized deformable part 30 of this embodiment includes an elastic telescopic structure 31, which is installed on the first inner wall. The abutting end is located at the end of the elastic telescopic structure 31 near the moving part 20. When the energized deformable part 30 is in a limited position, the abutting end abuts against the end of the moving part 20. The energized deformable part 30 includes the elastic telescopic structure 31, utilizing its telescopic and elastic restoring characteristics to avoid the moving part 20 in the energized state and to limit the moving part 20 in the de-energized state. In the energized state, the elastic telescopic structure 31 overcomes its elastic retraction, allowing the abutting end to avoid the moving part 20; while in the de-energized state, the elastic telescopic structure 31 returns to its original shape through elastic force, allowing the abutting end to abut against the moving part 20, thus achieving limitation.

[0072] See Figures 2 to 7As shown, the elastic telescopic structure 31 of this embodiment includes a first conductive structure 311 and an energized compression spring 312 connected to the first conductive structure 311. The first conductive structure 311 is mounted on the first inner wall, and its abutting end is located at the end of the energized compression spring 312 near the moving part 20. The first conductive structure 311 is used to connect to an external power source to electrically connect the energized compression spring 312. The energized compression spring 312 is the main component for generating elastic force. Utilizing the telescopic characteristics and elastic reset characteristics of the elastic telescopic structure 31, it achieves avoidance of the moving part 20 in the energized state and limitation of the moving part 20 in the non-energized state. The compression deformation of the energized compression spring 312 generates elastic force. By setting the length of the energized compression spring 312, the abutting force against the moving part 20 can be increased. In the limited state, this additional abutting force makes the connection between the moving part 20 and the abutting end tighter, increasing the stability and reliability of the system. See also Figure 2 As shown, in one embodiment of this application, a receiving space is provided at the first inner wall, and in the energized state, the elastic telescopic structure 31 retracts into the receiving space.

[0073] See Figures 2 to 7 As shown, the elastic telescopic structure 31 of this embodiment further includes a second conductive structure 313 and at least two energized compression springs 312. The second conductive structure 313 is connected to the end of each energized compression spring 312 near the moving part 20. Multiple energized compression springs 312 together form a circuit, providing a current transmission path for the energized deformation part 30, thereby realizing energized control of the elastic telescopic structure 31 without the need for separate wiring, avoiding circuit breakage during repeated extension and retraction. By utilizing multiple energized compression springs 312 to form a circuit, the use of additional wires or connectors can be avoided, thus simplifying the electrical connection design of the lens module. This not only reduces the complexity of circuit connections but also lowers system cost and maintenance difficulty. The use of multiple energized compression springs 312 can significantly increase system stability. Since each energized compression spring 312 can provide additional support and stability, the entire elastic telescopic structure 31 can be subjected to force more evenly during operation. For example, there are two second conductive structures 313 and energized compression springs 312, one of which is the outgoing path and the other is the return path.

[0074] See Figures 2 to 7As shown, in this embodiment of the application, a first insulating portion 3131 is provided at the end of the second conductive structure 313 near the moving part 20. This prevents electrical short circuits or interference between the conductive structure and the moving part 20. The first insulating portion 3131 effectively isolates the direct contact between the second conductive structure 313 and the moving part 20, avoiding unexpected currents 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 moving part 20, the risk of system failure can be reduced, ensuring that the lens module can operate stably and reliably under various operating conditions. The first insulating portion 3131 can be made of polymer materials such as polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), and polytetrafluoroethylene (PTFE). These polymer materials have excellent insulation properties, are wear-resistant and corrosion-resistant, and are easy to process into various shapes, therefore they are commonly used in insulating components in electronic devices. Rubber materials such as silicone, nitrile rubber (NBR), and acrylic rubber (ACM) can also be used. Rubber materials possess good elasticity and abrasion resistance, as well as good insulation properties, making them suitable for applications requiring flexible sealing and insulation. Resin materials, such as epoxy resin, polyamide resin (PA), and phenolic resin, offer excellent insulation properties, high-temperature resistance, and chemical resistance, making them suitable for insulation requirements in high-temperature, high-pressure, or special environments.

[0075] See Figures 8 to 15 As shown, the energized deformation section 30 with an elastic compression structure is suitable for scenarios where the space of the receiving cavity 11 is relatively sufficient. In some embodiments where the receiving cavity 11 is smaller, the energized deformation section 30 of this application embodiment includes an elastic bending structure 32. The elastic bending structure 32 is installed inside the receiving cavity 11, and the abutment end is disposed at the end of the elastic bending structure 32. When the energized deformation section 30 is in a limited state, the abutment end abuts against the end or side of the moving part 20. The elastic bending structure 32 is installed inside the receiving cavity 11, making use of the limited space of the receiving cavity 11 and effectively saving 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 section 30, it does not need to provide compression space, and can better adapt to the use scenarios where the receiving cavity 11 is smaller, thereby further reducing the size of the entire lens module and making it more compact.

[0076] See Figures 10 to 15As shown, the elastic bending structure 32 of this embodiment includes a third conductive structure 321 and an energized deformation spring 322. The third conductive structure 321 is mounted on the base 10, and the energized deformation spring 322 is mounted on the end of the third conductive structure 321, with the abutting end located at the end of the energized deformation spring 322 away from the third conductive structure 321. The third conductive structure 321 not only supports the energized deformation spring 322 but also transmits power to it. Through the third conductive structure 321, power can be effectively transmitted from the base 10 to the energized deformation spring 322, thereby controlling the elastic bending structure 32. The above-mentioned power transmission mechanism ensures that the energized deformation part 30 can accurately perform limiting or avoidance actions during operation, thus ensuring the stability and reliability of the lens module. The third conductive structure 321 extends along the gap between the side of the moving part 20 and the base 10, supporting the elastic bending structure 32 in 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 Figure 16 , Figure 17 , Figure 19 and Figure 20 As shown, the elastic bending structure 32 of this embodiment further includes a second insulating portion 323, which is disposed at the end of the energized deformable spring 322 away from the third conductive structure 321, forming a contact end. The second insulating portion 323, disposed at the end of the energized deformable spring 322 away from the third conductive structure 321, effectively isolates the circuit between the energized deformable spring 322 and the moving part 20. Even when the energized deformable part 30 is working, current will not flow directly to the moving part 20 through the contact end, thereby reducing the risk of circuit interference and short circuits. 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 deformable part 30 is working, the contact end interacts with the moving part 20, achieving precise control of the position of the moving part 20. The second insulating portion 323 can be made of polymer materials such as polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), and polytetrafluoroethylene (PTFE). These polymer materials possess excellent insulation properties, are wear-resistant and corrosion-resistant, and are easily processed into various shapes, making them commonly used in insulating components of electronic devices. Rubber materials, such as silicone, nitrile rubber (NBR), and acrylic rubber (ACM), offer good elasticity and wear resistance, while also possessing good insulation properties, making them suitable for applications requiring flexible sealing and insulation. Resin materials, such as epoxy resin, polyamide resin (PA), and phenolic resin, exhibit excellent insulation properties, high-temperature resistance, and chemical resistance, making them suitable for insulation requirements in high-temperature, high-pressure, or special environments.

[0078] See Figure 18 and Figure 21 As shown, the elastic bending structure 32 of this embodiment further includes a friction-enhancing portion 324, which is disposed at the end of the energized deformable spring 322 away from the third conductive structure 321. The friction-enhancing portion 324 forms abutment end, and is made of insulating material. The friction-enhancing portion 324 is part of the energized deformable spring 322, located at its end away from the third conductive structure 321. Because the friction-enhancing portion 324 is made of insulating material and contacts the moving part 20, it provides additional friction. The increased friction effectively stabilizes the position of the moving part 20, reducing its swaying and instability during movement. The friction-enhancing portion 324, being made of insulating material, effectively prevents current from flowing to the moving part 20, thereby reducing the risk of circuit interference and short circuits. The friction-enhancing portion 324 can be made of polyimide (PI): polyimide has excellent insulation properties, high temperature resistance, and chemical corrosion resistance, making it suitable for use in high-temperature environments and harsh conditions. Polytetrafluoroethylene (PTFE): PTFE possesses excellent insulation properties, chemical stability, and abrasion resistance, remaining stable in various environments. Polyetherketone (PEEK): PEEK exhibits excellent insulation properties, abrasion resistance, and chemical corrosion resistance, making it suitable for applications requiring high strength and durability. Polyurethane (PU): Polyurethane offers good insulation properties and abrasion resistance, along with high elasticity and flexibility, making it suitable for components requiring bending or flexing. Fluororubber (FKM): FKM possesses excellent oil resistance, corrosion resistance, and abrasion resistance, making it suitable for insulating components in some special environments.

[0079] The presence of the friction-enhancing part 324 and the second insulating part 323 can prevent the energized deformation structure from directly rubbing against the moving part 20, thus avoiding damage to the moving part 20. At the same time, it can prevent the generation of dust from friction, which would affect the imaging and adjustment of the lens module.

[0080] See Figure 10 , Figure 11 and Figures 14 to 18 As shown, in one embodiment, in the limited state, the bending direction of the energized deformation spring 322 is towards the side of the moving part 20. When the energized deformation part 30 is in the limited state, the energized deformation spring 322 is in its initial state, bending towards the side of the moving part 20, and the abutting end abuts against the moving part 20, using friction to restrict its movement, thereby ensuring that the moving part 20 is in a stable position; while when the energized deformation part 30 is in the avoidance state, the bending angle of the energized deformation spring 322 decreases, and the abutting end avoids the side of the moving part 20, allowing it to move freely to adapt to different adjustment needs.

[0081] See Figures 12 to 14 and Figures 19 to 21As shown, in the limited-position state of this embodiment, the bending direction of the energized deformation spring 322 is towards the end of the moving part 20. When the energized deformation part 30 is in the limited-position state, the energized deformation spring 322 is in its initial state, bending towards the end of the moving part 20, and the abutment end abuts against the end of the moving part 20, using pressure to restrict its movement, thereby ensuring that the moving part 20 is in a stable position; while when the energized deformation part 30 is in the avoidance state, the bending angle of the energized deformation spring 322 decreases, and the abutment end avoids the end of the moving part 20, allowing it to move freely to adapt to different adjustment needs. The difference is that, in this embodiment, when the energized deformation part 30 is in the avoidance position, there is a preset distance between the abutment end and the end of the moving part 20 to provide sufficient space for the movement of the moving part 20.

[0082] See Figures 10 to 21 As shown, the energized deformable spring 322 of this embodiment includes two electrical connecting pieces 3221, and the third conductive structure 321 includes two conductive pieces 3211, which are respectively connected to the two electrical connecting pieces 3221. Each conductive piece 3211 is connected to one electrical connecting piece 3221, forming a circuit. Since each conductive piece 3211 is connected to one electrical connecting piece 3221, the integrity of the circuit can be ensured.

[0083] See Figure 14 and Figure 15 As shown, in this embodiment of the application, there are multiple energized deformable springs 322. 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 inside the base 10, and the multiple energized deformable springs 322 are installed one-to-one on the multiple conductive ends. This enhances the control capability of the moving part 20 position. Through the synergistic effect of multiple energized deformable springs 322, the position and movement of the moving part 20 can be adjusted and controlled more precisely. This ensures smooth current transmission and maintains a stable connection state. Even if one of the energized deformable springs 322 malfunctions, the other energized deformable springs 322 can still continue to work without affecting the operation of the entire system. Integrating multiple conductive ends onto a single conductive body facilitates installation and transportation of components.

[0084] In this embodiment, a first electromagnetic drive unit is provided on the base 10, and a second electromagnetic drive unit is provided on the mover 20. The mover 20 is driven to move by the magnetic force between the first and second electromagnetic drive units. The first and second electromagnetic drive units are respectively composed of an electromagnetic coil and a magnetic material. 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 20 to achieve functions such as focusing, zooming, or image stabilization.

The cover plate 60 has lens clearance holes, the positions of which correspond to the positions of the lens module. The lens module is the aforementioned lens module. The electronic device also includes an image sensing unit mounted on the mid-frame 40, located at one end of the lens module. Light can pass through an optical unit 21 to reach the image sensing unit. The moving part 20 moves in the direction of the optical axis of the lens module, i.e., towards the optical axis of the photosensitive image sensor. The mid-frame 40 is the main frame of the electronic device, used to support and assemble other components. The screen assembly 50 is mounted on one side of the mid-frame 40 and is typically used to display images or other information. The cover plate 60 is mounted on the other side of the mid-frame 40 and is used to protect internal components or enhance the aesthetics of the device. One or more lens clearance holes are provided on the cover plate 60, these holes being located in specific positions corresponding to the positions of the lens module.

This electronic device can be a smartphone, tablet, laptop, game console, smartwatch, etc. The movable part 20 refers to a movable component within the lens module, typically used for functions such as adjusting focus, focusing, or optical stabilization.
