[0002] In the manufacturing process of camera modules, for camera modules with complex structures and specific functions, customers often need to customize some parts on the camera modules to achieve the desired effect. For example, a metal ring is added to the camera module. The bottom surface of the metal ring plays a smooth reflective role, which is used to emit and diverge the light of the camera module LED, thereby playing a role of diffuse lighting. The structure of the metal ring is usually irregular, with a smooth surface and a very thin edge. During assembly, it is easy to cause damage to the metal ring. At the same time, if it is assembled by manual pressing, it is easy to deviate, and it is also easy to damage the operator's hand.

[0023] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.

[0024] Please combine Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a camera module metal ring locking assembly positioning structure includes: a camera module 100 and a locking positioning member 200, the camera module 100 includes a lens 110 and a metal ring 120, the metal ring 120 is provided with a mounting hole 121, and the lens 110 is inserted into the mounting hole 121; the locking positioning member 200 includes a driving handle 210 and a positioning member 220, a positioning cavity 221 is formed on the positioning member 220, the driving handle 210 is arranged on a side surface of the positioning member 220 away from the positioning cavity 221, the structure of the positioning cavity 221 is adapted to the surface structure of the metal ring 120, and a soft buffer layer is arranged in the positioning cavity 221; when the surfaces of the positioning member 220 and the metal ring 120 are in contact with each other, the driving handle 210 is used to drive the positioning member 220 to rotate so that the metal ring 120 and the lens 110 are locked.

[0025] It should be noted that, since the surface structure of the metal ring 120 is irregular, the surface is smooth, and the edge is thin, it is easy to damage the metal ring 120 when the metal ring 120 is locked to the lens 110. Therefore, the locking of the metal ring 120 is positioned and protected by the positioning member 220 in the locking positioning member 200. Specifically, the outer structure of the positioning cavity 221 in the positioning member matches the outer structure of the surface of the metal ring 120, so that the positioning cavity 221 can fit tightly with the surface of the metal ring 120. Furthermore, by providing a soft buffer layer on the positioning cavity 221, the soft buffer layer can provide a buffering protection for the metal ring to prevent the surface of the metal ring 120 from being damaged. For example, hard tools can cause damage and deformation to the periphery of the metal ring or cause the color to fall off. Therefore, the positioning member is provided, and a soft buffer layer is provided on the positioning cavity on the positioning member. The soft buffer layer can prevent the metal from being damaged or the paint from peeling off. Furthermore, due to the flexible nature of the soft buffer layer, when the positioning piece 220 is squeezed, the soft buffer layer can discharge the gas between the positioning cavity 221 and the metal ring 120, so that the positioning cavity 221 and the metal ring 120 form a tighter fit to generate a greater adsorption force. At the same time, the friction between the soft buffer layer and the metal ring can be used to prevent the positioning piece 220 from being displaced when the driving handle 210 is used to drive the positioning piece 220 to rotate, thereby ensuring that the metal ring will not be displaced when it is locked and connected to the lens, thereby improving the assembly quality. In addition, by assembling the metal ring by locking the positioning piece, the operator can also avoid being cut by the metal ring 120 by directly grabbing the metal ring with his hands, thereby improving the safety of the work.

[0026] In one embodiment, the surface of the metal ring 120 is in an umbrella-shaped structure, and the structure of the positioning cavity 221 is adapted to the surface structure of the metal ring 120. Correspondingly, the positioning cavity 221 is also in an umbrella-shaped structure to ensure that the positioning cavity 221 and the metal ring 120 can fit tightly; further, the positioning member 220 is also in an umbrella-shaped structure as a whole, that is, the side of the positioning member 220 away from the positioning cavity 221 is also in an arc-shaped structure, and the size of the arc-shaped structure is close to the size of the positioning cavity 221, so that after the external force is applied, the force applied to the metal ring by the internal soft buffer layer is ensured to be uniform, thereby avoiding uneven force and damage to the metal ring.

[0027] Preferably, the positioning member 220 is made of acrylic or metal material, that is, the positioning member 220 should be made of a hard material to ensure the rigidity of the positioning member 220 .

[0028] Preferably, the soft buffer layer is made of rubber. By applying rotation and downward pressure to the positioning member 220, the rubber and the surface of the metal ring are closely attached to generate adsorption force and friction force, thereby driving the metal ring 120 to rotate, so that the metal ring 120 and the lens 110 are locked and fixed, so that the locking effect can be achieved without damaging the metal ring 120.

[0029] In one embodiment, the driving handle 210 is made of acrylic or metal. Similarly, the driving handle 210 needs to be made of a hard material to ensure that the driving handle 210 has sufficient rigidity.

[0030] Furthermore, the outer surface of the driving handle 210 is a roughened surface, that is, the outer surface of the driving handle 210 is roughened to prevent the driving handle 210 from being too rough to damage the operator's hand, and from being too smooth to make it inconvenient for the operator to apply force and control.

[0031] Preferably, the driving handle 210 is in a square structure. At the same time, the four corners of the driving handle 210 are provided with rounded corner structures. When an automatic locking tool is required, that is, when manual auxiliary locking is not performed, the driving handle 210 can be installed on the automatic locking tool. Therefore, the rounded corner structures are provided at the four corners, which can facilitate the driving handle 210 to be embedded in the clamping position of the automatic locking tool, thereby forming a stable structure.

[0032] In one embodiment, an internal thread 121a is provided in the mounting hole 121, an external thread is provided on the outer surface of the lens, and the metal ring 120 is threadedly connected to the lens 110. This ensures that the locking between the metal ring 120 and the lens 110 is sufficiently strong, thereby ensuring that each component in the entire camera module is firm and does not shake.

[0033] Furthermore, the camera module 100 further includes a rubber frame 130 and a PCB board 140, a first avoidance hole 131 is provided on the rubber frame 130, a second avoidance hole 141 is provided on the PCB board 140, and a plurality of LED lights 142 are provided on the PCB board 140, each LED light 142 is provided around the second avoidance hole 141, and the lens 110 passes through the first avoidance hole 131, the second avoidance hole 141 and the mounting hole 121, and is locked with the metal ring 120. In this way, the locking positioning member 200 can further ensure that the locking between the metal ring and the lens is sufficiently firm, so that the components of the entire camera module are more firm and do not shake.

[0034] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
