The bracket 10 is disposed in the through hole 200 and overlaps the lug 100 on the circuit board 20.

The camera unit 1 includes a prism group, a focus motor, a filter, a sensor, a housing of the camera, and the like, and the present invention does not substantially modify the same, and details are not described herein again. Since the camera unit 1 can be embedded Into the circuit board 20, the thickness of the circuit board 20 may not be deliberately designed when designing the electronic device, and the sum of the height of the camera unit 1 and the thickness of the circuit board 20 is the height of the camera unit 1. Thus, the installation position of the circuit board 20 is more flexible. As shown in FIG. 1, the bottom surface of the camera unit 1 is attached to the back surface of the display screen 2. By designing the position of the lug 100 in the height direction of the bracket 10, the circuit board can be flexibly configured. The mounting height of the circuit board 20 can be used as a structural member for fixing the camera unit 1. At the same time, various components on the circuit board 20 have more design space and are more flexible in design.

Here, the bracket 10 is made of plastic, and each of the outer walls of the side is provided with a plurality of lugs 100, which can ensure that the camera unit 1 is not easily flipped or skewed after being fixed on the circuit board 20, and the shooting accuracy is higher and the user experience is better.

As shown in FIG. 2 , the bracket 10 includes a frame 11 , and the lug 100 is disposed on the frame 11 , and the lug 100 is recessed from the end surface of the bracket 10 to form a recess 101 that communicates with the placement space of the camera unit 1 . The outer wall of the casing (not shown) of the camera unit 1 is correspondingly provided with a limiting portion (not shown). When the camera unit is mounted in the frame 11, the limiting portion is overlapped in the corresponding concave portion 101, in the longitudinal direction. Limit the camera unit on the top. At the same time, the recess 101 can also be used as an operation portion for taking out the camera unit 1 conveniently.

As shown in FIG. 2 and FIG. 3, at least one strip-shaped hole 102 is formed in the bottom of the bracket 10 of the present embodiment, and the flexible circuit board 1a of the camera unit 1 is taken out from the strip-shaped hole 102, and the wiring is convenient.

The present invention is not limited thereto. In one embodiment, the bracket 10 is a frame structure, and the camera unit is fixed on the inner surface of the side wall of the bracket 10. For example, the inner wall of the bracket 10 is convexly provided with an elastic holding portion, and the card portion is stuck. Hold on the outer wall of the camera unit.

As another embodiment, the bracket 10 includes a frame body 11, and the bottom of the frame body 11 has a plurality of ribs extending from the at least two opposite side walls toward the opposite side, and the camera unit can be carried on the ribs. Alternatively, the bracket 10 includes the frame body 11, and the bottom of the frame body 11 is hollowed out, and the concave and convex portions at the bottom of the camera unit can be correspondingly embedded in the bottom of the hollow, and the thickness can be reduced.
