Detailed Implementation Methods

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0034] Please see Figures 1-10 As shown, this utility model provides a camera module 100, which includes at least two lens driving devices 10.

[0035] Each of the lens driving devices 10 includes a rectangular housing 1, a support frame 2, a lens barrel bracket 3, an elastic component 4, and a first driving component 5.

[0036] The outer casing 1 includes a base 11, a top cover 12 covering the base 11, and a central hole 13 penetrating both the base 11 and the top cover 12. The support frame 2 is a rectangular ring structure with a receiving space, facing the base 11 and movably supported by it. The lens barrel bracket 3 is received within the receiving space and spaced apart from the support frame 2, and is used to mount the lens module 7. The elastic component 4 elastically suspends the lens barrel bracket 3 within the receiving space; the first drive component 5 is used to drive the lens barrel bracket 3 to move. The support frame 2 faces the base 11 and is movably supported by it. The lens barrel bracket 3 is received within the receiving space and spaced apart from the support frame 2, and is used to mount the lens module 7. The elastic component 4 elastically suspends the lens barrel bracket 3 within the receiving space; the first drive component 5 is used to drive the lens barrel bracket 3 to move.

[0037] Two lens driving devices 10 are arranged side by side, either horizontally or vertically. In each lens driving device 10, the side of its housing 1 that abuts against the other lens driving device 10 is defined as the splicing edge 14, and the other sides are defined as mounting edges 16. The angle in the housing 1 connected to its splicing edge 14 is defined as the splicing angle 15, and the other angles are defined as mounting angles 17. At most one of the first driving components of two adjacent lens driving devices 10 arranged side by side is located at the splicing edge 14 and the splicing angle 15. Alternatively, when both first driving components 5 of two adjacent lens driving devices 10 arranged side by side are simultaneously located at their respective splicing edges 14, the two first driving components 5 are spaced apart from each other along the length direction of the two splicing edges 14. Two lens driving devices 10 are arranged side by side, wherein the first driving component 5 of one lens driving device 10 is spaced apart from the first driving component 5 of the other lens driving device 10 along the side closest to the lens barrel support 3. By setting the first drive components 5 of the two lens barrel drive devices on the two sides of the housing 1 respectively, it is convenient to install and place multiple lens modules 7; at the same time, it can also improve the anti-magnetic interference capability.

This improves the resistance to magnetic interference. Wherein, C1 is one of the splicing angles 15 of the first lens driving device 10, and C21 is one of the mounting angles 17 of the second lens driving device 10. C1 and C21 are corresponding angles, and C21 and C22 are adjacent interior angles. Specifically, the first driving components 5 of the two lens driving devices 10 can be mounted as C1 and C21, or C1 and C22.

This improves the resistance to magnetic interference. The first drive components 5 of the two lens drive devices 10 are installed in a configuration such as C1 and L2, or L1 and C2, etc.
