Description

Technical Field

[0001] The invention relates to the technical field of an integrated wire clamping claw structure, a camera device and electronic equipment. Background Art

[0002] The wire clamping jaw is a part of the structure of an optical image stabilization device with shape memory alloy, and is composed of an upper wire clamping jaw, a lower wire clamping jaw and their connecting parts. The upper wire clamping jaw is fixed to the moving part by welding and moves together with the moving part; the lower wire clamping jaw is integrally formed with the circuit board and fixed to the base surface by glue dispensing, forming a fixed part with the base. A memory alloy wire is clamped between the two jaws, and the length of the memory alloy wire is changed by supplying power to the memory alloy wire, thereby driving the movement of the moving part.

[0003] However, the wire clamping claws in the prior art have the following defects:

[0004] 1. The upper clamping jaw is formed and bent separately, and the lower clamping jaw is formed and bent together with the circuit board. The flatness consistency of the two parts after bending is poor, resulting in the non-horizontal state of the optical image stabilization device;

[0005] 2. Since the lower wire clamping jaw is bent together with the circuit board, the circuit board is easily damaged, and the process is difficult. At the same time, it is necessary to newly open the lower wire clamping jaw and circuit board bending fixture, which is costly. Summary of the invention

[0006] The present invention mainly solves the technical problems existing in the prior art, thereby providing an integrated wire clamping claw structure, a camera device and an electronic device with good planar motion consistency, less process difficulty and low cost.

[0007] The above technical problems of the present invention are mainly solved by the following technical solutions:

[0008] The integrated wire clamping jaw structure provided by the present invention comprises:

[0009] An outer frame, wherein the outer frame can be cut into a plurality of outer frame units;

[0010] A wire clamping jaw, wherein the wire clamping jaw is formed in one piece inside the outer frame, and the wire clamping jaw comprises an upper wire clamping jaw and a lower wire clamping jaw which are arranged at intervals, and the upper wire clamping jaw and the lower wire clamping jaw are located in the same plane;

[0011] A moving component, wherein the moving component is arranged inside the outer frame, and the corners of the moving component are fixedly connected to the upper wire clamping claw;

[0012] A circuit board is arranged inside the outer frame and below the moving component, and corners of the circuit board are fixedly connected to the lower wire clamping claw.

[0013] Furthermore, the upper wire clamping jaw and the lower wire clamping jaw are respectively connected to the moving component and the circuit board by welding.

[0014] Furthermore, the interior of the outer frame is rectangular.

[0015] Furthermore, the upper wire clamping jaws are arranged on two corners of one diagonal line of the rectangle inside the outer frame, and the lower wire clamping jaws are arranged on two corners of another diagonal line of the rectangle inside the outer frame.

[0016] Furthermore, a shape memory alloy wire is connected between the upper wire clamping jaw and the lower wire clamping jaw. When the outer frame is cut into a plurality of outer frame units and the shape memory alloy wire is energized, the upper wire clamping jaw and the lower wire clamping jaw move relative to each other, driving the moving component to move relative to the circuit board.

[0017] Furthermore, the upper wire clamping jaw and the lower wire clamping jaw have the same shape.

[0018] The camera device of the present invention comprises the above-mentioned integrated wire clamping claw structure.

[0019] The electronic device of the present invention comprises the above-mentioned camera device.

[0020] The beneficial effect of the present invention is that: by separating the existing upper wire clamping jaw and the lower wire clamping jaw into an integrated clamping jaw through an integrated molding method, the consistency of the height and flatness of the upper wire clamping jaw and the lower wire clamping jaw after bending can be effectively improved, the consistency of the optical image stabilization device during the planar movement can be ensured, the overturning and deflection of the lower wire clamping jaw and the upper wire clamping jaw can be reduced, the process difficulty of bending the circuit board can be greatly reduced, and the product manufacturing yield can be effectively improved.
