Description

Technical Field

[0001] This application belongs to the field of electronic device imaging, and particularly relates to an integrated locking latch for aperture, a connecting structure, an aperture driving device, and an imaging module. Background Technology

[0002] In mobile phone photography, the concept of the aperture drive mechanism differs somewhat from that of traditional cameras, but it remains an important component of mobile phone cameras. Due to their small size and design limitations, mobile phones typically have a fixed aperture, or only a limited number of adjustable aperture settings.

[0003] The aperture in a mobile phone typically uses an electric mechanism controlled by the system. In most cases, the opening and closing of the aperture is achieved by a small motor connected to the camera module.

[0004] The image processing algorithm in the phone adjusts the aperture size based on the ambient light intensity, shooting scene, and user-selected mode to achieve optimal exposure and effect.

[0005] In existing technologies, during the assembly of the aperture drive mechanism, the latches and the integrated connecting rods attached to the blades are set up one-to-one. This process is cumbersome during production, as the latches must be assembled individually and it is difficult to maintain consistency, resulting in low production efficiency and increased costs. In addition, even minor errors during assembly can easily lead to inaccurate aperture adjustment, affecting the shooting results. Utility Model Content

[0006] The purpose of this utility model is to address the above-mentioned problems by providing an integrated locking mechanism, connecting structure, aperture driving device, and camera module for apertures that can solve the aforementioned technical issues.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] An integrated locking mechanism for an aperture includes several locking parts arranged circumferentially around the optical axis and used to limit the movement of the aperture blade axis. Each of the locking parts is integrated with a connecting member.

[0009] Furthermore, a plurality of elastic locking portions are connected to the outer periphery of the connector.

[0010] Furthermore, the outer periphery of the connector is also connected to at least one elastic limiting part located between two adjacent locking parts.

[0011] Furthermore, in the circumferential direction of the connector, either the locking part or the elastic limiting part is distributed clockwise, and the other is distributed counterclockwise.

[0012] Furthermore, the connector is provided with a lug for receiving external force and extending inward to the inside of the connector.

[0013] This application also provides a connection structure for an integrated latch and an aperture bracket, including an aperture bracket, on which a track groove / hole is provided for the movement of the aperture blade axis, and an integrated latch for the aperture is mounted on the aperture bracket, which is circumferentially fixed relative to the aperture bracket and has a plurality of latching portions circumferentially distributed around the optical axis; at least a portion of the latching portion extends into the track groove / hole, and the latching portion and the track groove / hole form at least two shaft positions for the aperture blade axis to alternately enter.

[0014] Furthermore, the integrated locking mechanism for the aperture also includes a connector that is circumferentially fixed relative to the aperture bracket, and the outer periphery of the connector is connected to a plurality of locking portions that are integrally formed with the connector.

[0015] Furthermore, the locking part is an elastic locking part, and at least one elastic limiting part is also connected to the outer periphery of the connector. Either the locking part or the elastic limiting part is distributed clockwise, and the other is distributed counterclockwise. The elastic limiting part and the locking part fix the connector circumferentially relative to the aperture bracket.

[0016] Furthermore, the elastic limiting part is a cantilever elastic limiting part, and adjacent limiting part entry grooves and limiting part locking grooves are sequentially provided in the circumferential direction of the aperture bracket. The elastic limiting part enters the limiting part locking groove through the limiting part entry groove and the free end of the elastic limiting part abuts against the groove wall of the limiting part locking groove.

[0017] This application also provides an aperture driving device, which includes the connection structure of the integrated latch and the aperture bracket.

[0018] This application also provides a camera module, which includes the aforementioned aperture driving device.

[0019] Compared with existing technologies, the advantages of this application are: the locking buckle is designed and connected in an integrated manner, eliminating the need to assemble each buckle individually during the assembly process, simplifying the production process, reducing the number of parts and the minor errors between parts, making the processing and assembly process more efficient, ensuring that the rotation of each blade remains consistent during the movement process, and helping to reduce production costs.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0032] Example 1

[0033] like Figure 2 As shown, the aperture uses an integrated locking mechanism, which in this embodiment will be mounted on the aperture bracket 1;

[0034] Because existing locking mechanisms and integrated connecting rods attached to the blades are configured in a one-to-one correspondence, the assembly process is cumbersome and it is difficult to maintain consistency. Therefore, this application modifies the design of the locking mechanism.

[0035] Specifically, the aperture uses an integrated locking mechanism, the main structure of which includes several resilient locking parts 3 for limiting the movement of the aperture blade shaft 2. These locking parts 3 are uniformly connected in a circular shape around the optical axis Z to a connecting member 30, which is annular. That is, the locking parts 3 are integrated with the connecting member 30. In other embodiments, the locking parts 3 are non-uniformly distributed along the circumference of the optical axis Z. In other embodiments, the connecting member 30 may also be a non-closed annular shape with a notch, or an arc shape.

[0036] For example, taking a spring sheet as an example, the connector 30 and several locking parts 3 connected to the outer periphery of the connector 30 can be directly obtained through etching and other forming methods.

[0037] This approach ensures that the quality of the integrated aperture latch in this embodiment remains highly consistent. At the same time, it can improve the production efficiency of the integrated aperture latch during the production stage and avoid the problem of cumbersome processing of a single latch part 3.

[0038] The integrated structure allows all the locking parts 3 to be installed together, avoiding the problems of cumbersome assembly and low efficiency caused by individual assembly, making the assembly process more efficient and helping to reduce production costs.

[0039] Secondly, by integrating the connector 30 and the locking part 3 into a single structure, all locking parts 3 can be positioned in the set installation position, thereby improving installation accuracy and positional consistency, and thus improving the movement accuracy of the aperture blades.

[0040] In addition, the connector 30 and the locking part 3 are integrated into one structure, which can greatly reduce the problem of low efficiency caused by the separate tray placement and transfer of a single locking part 3 during the production process.

[0041] like Figure 6 As shown, the structure of the locking part 3 includes a cantilevered main body 300 connected to the outer wall of the connector 30, a detour part 301 connected to the suspended end of the cantilevered main body 300, and an elastic bending part 302 connected to the end of the detour part 301 away from the cantilevered main body 300. The end of the elastic bending part 302 away from the detour part 301 is free. The side of the elastic bending part 302 near the connector 30 has a plurality of local shaft positions 303 that at least partially match the aperture blade shaft 2. The aperture blade shaft 2 is restricted to move on the corresponding local shaft positions 303, that is, the aperture blade shaft 2 can reciprocate between two adjacent local shaft positions 303.

[0042] Furthermore, the detour portion 301 is U-shaped or S-shaped, while the elastic bending portion 302 is approximately "M"-shaped. The local axis position 303 can be understood as a feature that mimics at least part of the outer peripheral surface of the aperture blade axis 2.

[0043] In other embodiments, the shape of the latching part 3 can be other shapes, such as a smooth arc, a broken line, or a straight line.

[0044] In this embodiment, the connector 30 is also designed with an elastic limiting part 31 that cooperates with the aperture bracket 1. The elastic limiting part 31 consists of several limiting structures that are evenly distributed in a clockwise or counterclockwise direction around the connector 30. The locking part 3 is distributed in the opposite direction to the elastic limiting part 31. The advantage of this is that the relative distribution of the two allows the locking part 3 and the elastic limiting part 31 to support each other more effectively when subjected to circumferential torsional pressure, thereby enhancing the overall structure's resistance to pressure and torsion, and achieving the purpose of circumferential locking.

[0045] In a preferred embodiment, the elastic limiting part 31 is a curved or arc-shaped elastic limiting cantilever, that is, the suspended end of the elastic limiting part 31 is free. At this time, the elastic limiting part 31 itself has a certain elasticity, which is conducive to the installation of the entire integrated lock.

[0046] Secondly, with reference to the appendix of this embodiment Figure 3 Taking the angle as an example, in this embodiment, the elastic limiting part 31 is distributed in a counterclockwise direction, while the locking part 3 is distributed in a clockwise direction.

[0047] During installation, the elastic limiting part 31 can be directly installed in the set installation position, or it can be installed in the set position by pre-installing and rotating the connecting part 30. The locking part 3 moves synchronously with the elastic limiting part 31.

[0048] By designing counterclockwise and clockwise directions, the connector 30 can be prevented from rotating clockwise or counterclockwise around the optical axis Z when it is installed in the correct position, thus ensuring that the locking part 3 has very good locking stability for the aperture blade shaft 2 at the corresponding local axis position 303.

[0049] Furthermore, there are several elastic limiting parts 31, and the number of locking parts 3 in this embodiment is greater than the number of elastic limiting parts 31.

[0050] The following are several configuration options:

[0051] The first type has one elastic limiting part 31, which is connected to the outer wall of the connector 30 and located between two adjacent locking parts 3.

[0052] The second type involves more than one elastic limiting part 31 but less than the total number of locking parts 3. In this case, at least two sets of elastic limiting parts 31 are connected to the outer wall of the connector 30 in the circumferential direction, with each set consisting of two adjacent locking parts 3. That is, there are two locking parts 3 between two adjacent elastic limiting parts 31.

[0053] In another embodiment, the number of locking parts 3 can also be equal to the number of elastic limiting parts 31. In this case, there is an elastic limiting part 31 between each two adjacent locking parts 3.

[0054] In order to further improve production and assembly efficiency, a fixed lug 32 is provided on the inner side of the ring of the connector 30. The design of the lug 32 makes it easier for operators to apply external force. For example, during disassembly or installation, the operator can operate more easily through the gripping points provided by the lug 32, and can also rely on the lug 32 for positioning.

[0055] In a preferred embodiment, there are two lugs 32 that are symmetrically distributed about the axis of the connector 30. Each lug 32 has a lug hole to facilitate the insertion of a tool and to move the connector 30. It also facilitates the rotation of the connector 30 at a certain angle so that the connector 30 can be installed in place.

[0056] Secondly, the lug 32 is connected to the inner wall of the connector 30, and the lug 32 and the connector 30 are perpendicularly connected. As another embodiment, the number of lugs 32 can also be three or four, etc., which will not be exhaustively listed here.

[0057] Example 2

[0058] The structure and principle of this embodiment are basically the same as those of Embodiment 1. The difference lies in the fact that, for the integrated locking buckle for the aperture in Embodiment 1, the connection structure between the integrated locking buckle and the aperture bracket in this embodiment includes the integrated locking buckle for the aperture.

[0059] This embodiment will further explain the mating mechanism of the integrated locking mechanism for the aperture described above.

[0060] like Figure 1 As shown, the connection structure between the integrated latch and the aperture bracket includes an aperture bracket 1 with the aforementioned integrated latch S1 for the aperture mounted on the top surface. Specifically, the integrated latch S1 for the aperture is centered on the optical axis Z. The integrated latch S1 for the aperture is fixed to the aperture bracket 1 by its elastic limiting part 31 and locking part 3. Furthermore, the aperture bracket 1 is also provided with... Figure 3 The track groove / hole 10 shown allows each locking part 3 of the integrated locking S1 of the aperture to partially extend into it. This track groove / hole 10 is used to limit and define the movement direction of the aperture blade shaft 2.

[0061] Specifically, such as Figure 4 As shown, the locking part 3 extending into the track groove / hole 10 forms three shaft positions 11 with the track groove / hole 10 for the aperture blade shaft 2 to alternately enter. That is, the aforementioned partial shaft position 303 and the groove wall or hole wall of the track groove / hole 10 form the shaft position 11 here. Figure 5 As shown, such as the first axis position 11a and the second axis position 11b, by setting multiple axis positions 11 in the track groove / hole 10, more precise aperture blade adjustment can be achieved, improving the flexibility and response speed of aperture adjustment, and enabling users to quickly adjust the aperture size under different shooting conditions.

[0062] In this embodiment, the limiting structure includes a limiting part entry groove 12 and a limiting part locking groove 13 on the aperture bracket 1 that cooperate with the elastic limiting part 31. The elastic limiting part 31 is a cantilever elastic limiting part, which can enter the limiting part locking groove 13 from the limiting part entry groove 12 without damage. Specifically, during assembly, the elastic limiting part 31 is first placed in the limiting part entry groove 12. After all the aperture blade shafts 2 are installed in the track groove / hole 10, the operator uses the lug 32 to rotate the connector 30 to drive the elastic limiting part 31 into the limiting part locking groove 13. At the same time, the free end of the elastic limiting part 31 abuts against the groove wall of the limiting part locking groove 13 to lock it, and the aperture is fixed to the aperture bracket 1 with an integrated lock S1.

[0063] Specifically, when the elastic limiting part 31 is located in the locking groove 13 of the limiting part, the free end of the elastic limiting part 31 abuts against the groove wall of the locking groove 13 of the limiting part to restrict the iris integrated lock S1 from rotating in one direction. Then, the locking part 3 locks the other direction, so that the iris integrated lock S1 cannot rotate clockwise or counterclockwise around the optical axis Z.

[0064] Example 3

[0065] The structure and principle of this embodiment are basically the same as those of Embodiment 2. The difference lies in the connection structure between the integrated latch and the aperture support in Embodiment 2. In this embodiment, the aperture driving device includes an integrated latch and an aperture support connection structure, as well as blades. The blades are connected to the aperture blade shaft 2. The blades can be fixedly connected to the aperture blade shaft 2, or they can rotate or slide relative to the aperture blade shaft 2. Two aperture blade shafts 2 can be provided on one blade. The integrated latch for the aperture in the above embodiment can be applied to any one of the aperture blade shafts 2 on one blade, or one integrated latch for the aperture can be provided for each aperture blade shaft 2. The latching part 3 can correspond one-to-one with the blades, or the latching part 3 can be provided only at the positions of the aperture blade shafts 2 corresponding to a few blades.

[0066] An aperture drive mechanism is a device used to control the opening and closing of aperture blades in a camera or other optical equipment. The primary function of the aperture is to regulate the amount of light entering the sensor or film, thereby affecting the exposure and depth of field of a photograph.

[0067] In automatic or semi-automatic mode, the camera's aperture drive automatically adjusts the aperture size based on feedback from the internal metering system. For example, in bright light, the drive will cause the aperture blades to close to reduce the amount of light entering the camera.

[0068] Example 4

[0069] The structure and principle of this embodiment are basically the same as those of Embodiment 3. The difference lies in that, for the aperture driving device of Embodiment 3, the camera module of this embodiment includes an aperture driving device.

[0070] like Figure 7 As shown, a camera module is a complete photographic device, typically including multiple components such as a lens, storage medium, display screen, and control panel. Outside the camera module, there are also external housings, control interfaces, displays, memory card slots, etc., forming a complete working system capable of performing various functions such as image capture, real-time preview, storage, playback / transmission, etc., representing a more advanced application.
