When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0044] Since the voice coil motor or position sensor is installed on the mounting base, a flexible circuit board is required to connect the voice coil motor or position sensor circuit on the mounting base to the interface at the outer end of the lens. In order to improve the connection reliability, the flexible circuit board needs to be stably positioned on the mounting base, but the existing flexible circuit board positioning method cannot guarantee stability.

[0045] In view of this, the present invention provides an optical zoom lens. Figures 1 to 3 An embodiment of the optical zoom lens provided by the present invention is as follows: Figures 4 to 11 This is an embodiment of the positioning structure 100 provided by the present invention. The optical zoom lens includes the positioning structure 100. The main inventive point of the present invention lies in the improvement of the positioning structure 100. The positioning structure 100 is mainly described below in conjunction with specific drawings.

[0046] Please refer to Figure 1The positioning structure 100 is used to fix the flexible circuit board 3 connected to the voice coil motor and the position sensor on the optical zoom lens. The positioning structure 100 includes an outer frame 1, a mounting seat 2 and a flexible circuit board 3. The mounting seat 2 is arranged at the frame opening of the outer frame 1. The mounting seat 2 is provided with a first positioning portion 21. The flexible circuit board 3 is arranged on the mounting seat 2. The flexible circuit board 3 is provided with a first matching portion 31. The first matching portion 31 and the first positioning portion 21 are positioned and matched with each other so that the flexible circuit board 3 and the mounting seat 2 are fixed to each other.

[0048] The frame opening of the outer frame 1 is provided with a mounting seat 2. For details, please refer to Figure 2 In this embodiment, the outer frame 1 is a square shell with openings at both ends to facilitate the extension of the flexible circuit board 3 while protecting the internal lens components.

[0049] Further, the outer frame 1 is provided with a second positioning portion 11, and the flexible circuit board 3 is provided with a second matching portion 32, and the second matching portion 32 and the second positioning portion 11 are positioned and matched with each other so that the flexible circuit board 3 and the outer frame 1 are fixed to each other.

Of course, the flexible circuit board 3 can also be directly extended through the edge of the frame opening of the outer frame 1 (please refer to Figure 1 ), this situation can reduce the process of punching holes in the installation of the flexible circuit board 3 and reduce the difficulty of installation.

[0050] The second positioning portion 11 is a positioning column, and the second matching portion 32 is a positioning hole. For details, please refer to Figure 3 In this embodiment, the positioning post is cylindrical, and correspondingly, the second matching portion 32 is a through hole with the same diameter as the positioning post. During installation, the flexible circuit board 3 is directly inserted into the positioning post through the through hole. In this way, the structure is simple and the installation is convenient.

[0051] The second positioning portion 11 is a fixing hole. The flexible circuit board 3 is provided with a connecting hole. The connecting hole is penetrated by a screw. The screw constitutes the second matching portion 32. For details, please refer to Figure 3 In this embodiment, the fixing hole is a circular hole with the same diameter as the connecting hole. During installation, the circular hole is used for positioning. At the same time, the screw can press the flexible circuit board 3 against the side wall of the outer frame 1 to prevent it from being accidentally pulled.

[0052] Furthermore, the second positioning portion 11 and the second matching portion 32 are provided in plurality, and the plurality of second positioning portions 11 correspond to the plurality of second matching portions 32 one by one, and the stability of the installation of the flexible circuit board 3 is further improved through the positioning and matching of the plurality of second positioning portions 11 and the plurality of second matching portions 32.

For details, please refer to Figure 1 , Figures 4 to 7 In this embodiment, the flexible circuit board 3 is S-shaped. When the mounting base 2 moves, the flexible circuit board 3 can be stretched to avoid the risk of being torn off.

[0056] The first positioning portion 21 is a positioning column, and the first matching portion 31 is a positioning hole. For details, please refer to Figure 1 , Figures 4 to 7 In this embodiment, the positioning column is cylindrical, and accordingly, the first matching portion 31 is a through hole with the same diameter as the positioning column. During installation, the flexible circuit board 3 is directly inserted into the positioning column through the through hole. In this way, the structure is simple and the installation is convenient.

[0057] The first positioning portion 21 is a fixing hole. The flexible circuit board 3 is provided with a connecting hole. The connecting hole is provided with a screw. The screw constitutes the first matching portion 31. For details, please refer to Figure 1 , Figures 4 to 7 In this embodiment, the fixing hole is a circular hole with the same diameter as the connecting hole. During installation, the circular hole is used for positioning. At the same time, the screw can press the flexible circuit board 3 onto the mounting base 2 to prevent it from being accidentally pulled.

[0058] The first positioning portion 21 is a buckle, which includes a main body extending in a direction away from the mounting seat 2 and a stopper provided on the main body and extending in a direction close to the flexible circuit board 3. The flexible circuit board 3 has a clamping portion for abutting against the stopper, and the clamping portion constitutes the first matching portion 31. During installation, the flexible circuit board 3 is clamped into the buckle to improve stability and prevent falling off.

[0059] There are multiple buckles, and at least two of the multiple buckles are respectively arranged on two opposite sides of the flexible circuit board 3. For details, please refer to Figure 1 , Figures 4 to 7 In this embodiment, there are two clips, and a mounting groove of the flexible circuit board 3 is defined between the two clips, providing a guide for its installation.
