Dual-camera modules are usually composed of a main camera and an auxiliary camera, which work together to achieve more complex shooting functions, such as optical zoom, portrait mode, etc. In the production process of dual-camera modules, manual focusing is usually adopted, that is, it is achieved by manually rotating the lens using a focusing jig. When one of the camera modules is adjusted, it is necessary to continue to synchronize with the other camera module. The focusing sequence and focusing height of the two identical camera modules are basically the same, so the two focusing are basically repeated actions, and the focusing efficiency is low.

[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] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a focusing fixture 10 for a dual-camera module comprises: a main focusing ring 100, a sub-focusing ring 200 and a synchronous focusing drive structure. The main focusing ring 100 is provided with a main focusing hole 110; the sub-focusing ring 200 is provided with a sub-focusing hole; the synchronous focusing drive structure is respectively arranged on the outer wall of the main focusing ring 100 and the outer wall of the sub-focusing ring. When the main focusing ring 100 is rotated, the synchronous focusing drive structure is used to coordinately drive the sub-focusing ring 200 to rotate.
[0025] It should be noted that the main focus ring 100 is connected to the auxiliary focus ring 200 through the synchronous focus drive structure. Then, when the main focus ring 100 is rotated, the auxiliary focus ring 200 can be driven to rotate at the same time through the synchronous focus drive structure. In this way, one focusing action can simultaneously achieve the focusing operation of two camera modules, thereby improving the focusing efficiency and maintaining the consistency of the focusing accuracy of the dual camera modules. In this embodiment, the structure of the main focus ring 100 is the same as that of the auxiliary focus ring 200.
[0026] See also Figure 1 and Figure 3As shown, in one embodiment, a first main boss 120 is provided on the outer wall of the main focus ring 100, and a first sub-boss 210 is provided on the outer wall of the sub-focus ring 200. The synchronous focus driving structure includes a first gear structure and a second gear structure, wherein the first gear structure is formed on the first main boss 120, and the second gear structure is formed on the first sub-boss, so that the first main boss 120 is meshed and connected with the first sub-boss 210. Since the main focus ring 100 and the sub-focus ring 200 are meshed by gears, it is necessary to ensure that the diameter of the first main boss 120 and the diameter of the first sub-boss 210 are large enough. When adjusting the dual camera module, only the main focus ring 100 needs to be rotated to drive the sub-focus ring 200 to rotate at the same time. Thus, one focusing action can be achieved, and the two camera modules can be focused at the same time. Preferably, the first main boss is a circular structure, and the first sub-boss is a circular structure. In this embodiment, the main focus ring 100 and the auxiliary focus ring 200 can be fixed by a connecting bracket, and a rotating structure is also provided on the connecting bracket. The rotating structure cooperates with the rotation of the main focus ring 100 and the auxiliary focus ring 200, and there is no need to set a bracket. During use, the relative positions of the main focus ring 100 and the auxiliary focus ring 200 are fixed by relying on the dual camera module.
[0027] See also Figure 2 and Figure 3As shown, in another embodiment, a second main boss 130 is provided at one end of the main focus ring 100, a second secondary boss 220 is provided at one end of the secondary focus ring 200, and the synchronous focus driving structure is a synchronous transmission belt 300, which is respectively connected to the second main boss 130 and the second secondary boss 220. When the main focus ring 100 is rotated, the synchronous transmission belt 300 is used to coordinately drive the secondary focus ring 200 to rotate. For example, the synchronous transmission belt 300 can be a transmission belt or a transmission chain; the main focus ring 100 and the secondary focus ring 200 are connected by the synchronous transmission belt 300, so as to achieve a focusing action once, and the focusing of the two camera modules can be completed. Preferably, the second main boss 130 is a circular structure, and the second secondary boss 220 is a circular structure. In this embodiment, a first limiting groove is provided on the second main boss 130, and a second limiting groove is provided on the second auxiliary boss 220. One end of the synchronous transmission belt 300 is sleeved in the first limiting groove, and the other end of the synchronous transmission belt 300 is sleeved in the second limiting groove. The synchronous transmission belt 300 is limited by the first limiting groove and the second limiting groove to avoid the synchronous transmission belt from shifting during the rotation process. Further, in order to improve the stability of the transmission, straight teeth are provided in the first limiting groove and the second limiting groove, so that the second main boss and the second auxiliary boss are gear structures. In this embodiment, the main focus ring 100 and the auxiliary focus ring 200 can be fixed by a connecting bracket, and a rotating structure is also provided on the connecting bracket. The rotating structure cooperates with the rotation of the main focus ring 100 and the auxiliary focus ring 200, and a bracket may not be provided. During use, the relative position of the main focus ring 100 and the auxiliary focus ring 200 is fixed by the dual-camera module.
[0028] In one embodiment, the diameter of the main focusing hole 110 gradually decreases from one end to the other end, so that the cross section of the main focusing hole 110 is a trapezoidal structure. That is, the diameter of the main focusing hole 110 is a structure that is wide at the top and narrow at the bottom. Figure 3 As shown, the aperture of the main focusing hole 110 is larger in the upward direction and smaller in the downward direction. The purpose is that the smaller hole in the downward direction is used for rotating with the lens. Since the field of view of the lens or module increases with the distance, the upward aperture needs to be larger to be compatible with the field of view of the camera module.
[0029] In one embodiment, the diameter of the auxiliary focusing hole gradually decreases from one end to the other end, so that the cross section of the auxiliary focusing hole is a trapezoidal structure. The auxiliary focusing hole has the same structure as the main focusing hole 110 and is provided for the same purpose.
[0030] In one implementation, the main focus ring 110 is made of stainless steel, such as copper, aluminum, etc., to prevent the main focus ring 110 from rusting.
[0031] In one implementation, the auxiliary focus ring is made of stainless steel metal, such as copper, aluminum, etc., to prevent the auxiliary focus ring 110 from rusting.
[0032] 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.
