Abstract

The present disclosure provides a camera device, including a housing assembly, and a camera module. The housing assembly includes a front housing, a rear housing, a housing body, and a first installation pin. The housing body is equipped with a first positioning hole. The first installation pin passes through the first positioning hole, and two opposite ends of the first installation pin are fixed to the front housing and the rear housing respectively to fix and connect the front housing and the rear housing. The housing body is tightly clamped by and fixed between the front housing and the rear housing. An installation space is surrounded by the front housing, housing body, and rear housing. The camera module is located in the installation space and fixed to the housing assembly. The camera device has a housing body clamped tightly by and fixed between the front housing and the rear housing.

First claim

What is claimed is:

1 . An antenna fixing assembly, comprising:
a frame body, wherein the frame body provides an installation space for accommodating functional modules, and the frame body is provided with a through hole communicating with the installation space; an installation bracket, wherein the installation bracket is detachably connected to the frame body and is at least partially placed in the installation space, and the installation bracket comprises a first installation portion arranged on a side of the installation bracket close to the through hole, and a first installation gap is formed between the first installation portion and the frame body; and an antenna module, wherein the antenna module is placed within the first installation gap, and the antenna module is movable with the installation bracket to abut against or detach from the frame body when being assembled on the frame body, wherein when the antenna module is assembled on the frame body, the through hole is at least partially aligned with the antenna module so that the antenna module is configured to send and receive signals through the through hole.

2 . The antenna fixing assembly of claim 1 , wherein the first installation portion is an installation slot, and the installation bracket comprises a notch for communicating to the installation slot arranged on a side of the installation bracket close to the through hole, so that a first installation gap is formed between a bottom of the installation slot and the frame body.

3 . The antenna fixing assembly of claim 2 , wherein a protruding limiting part is formed in the circumference of the installation slot, and the limiting part surrounds and defines a slot wall of the installation slot; and
wherein one end of the limiting part abuts against the frame body to define a minimum width of the first installation gap.

4 . The antenna fixing assembly of claim 1 , further comprising a cover plate, wherein the cover plate is detachably connected to the installation bracket and arranged between the frame body and the antenna module, and the cover plate covers the through hole; and
wherein the cover plate and the first installation portion together define the first installation gap.

5 . The antenna fixing assembly of claim 4 , wherein a buckle structure is arranged between the cover plate and the installation bracket, and the cover plate is connected to the installation bracket through the buckle structure; and
wherein the buckle structure comprises a first elastic buckle body and a buckle edge, and the buckle edge provides a buckling position for the first elastic buckle body to be buckled in and pressed against.

6 . The antenna fixing assembly of claim 4 , wherein a first positioning structure is arranged between the cover plate and the installation bracket, and the first positioning structure is configured to limit an installation position of the cover plate on the installation bracket; and
wherein the first positioning structure comprises a first positioning pin and a first positioning hole, and the first positioning hole provides a positioning space for embedding the first positioning pin.

7 . The antenna fixing assembly of claim 4 , wherein a second positioning structure is arranged between the cover plate and the frame body; and
wherein the second positioning structure has a shape matching the through hole, so that the second positioning structure is capable of being embedded in the through hole to limit a relative position between the frame body and the cover plate.

8 . The antenna fixing assembly of claim 1 , wherein the antenna module is attached to the first installation portion via double-sided adhesive.

9 . The antenna fixing assembly of claim 1 , wherein the installation bracket is provided with a pocket hole at a position corresponding to the first installation portion, so that the antenna module is exposed to the first installation portion through the pocket hole; and
wherein the antenna module is provided with a shielding cover at a position where the pocket hole is exposed.

10 . The antenna fixing assembly of claim 1 , wherein the frame body is provided with an installation port on a side away from the through hole; and
wherein the installation port communicates with an installation space and provides a disassembly and assembly position for the installation bracket.

11 . The antenna fixing assembly of claim 10 , wherein fixing arms are arranged at opposite ends of the installation bracket, and when the installation bracket is inserted into the installation space through the installation port, the fixing arms are hung on a rear side of the frame body; and
wherein each of the fixing arms is provided with a reference hole passing through each of the fixing arms, and the frame body is provided with a fixing hole corresponding to the reference hole around the installation port, and the reference hole and the fixing hole are positioned and installed via locking hardware.

12 . The antenna fixing assembly of claim 1 , wherein the antenna module comprises a first antenna plate arranged on the first installation portion;
wherein the first antenna plate is provided with an antenna body, an antenna circuit, and an interface circuit, and the antenna body, the antenna circuit, and the interface circuit are sequentially electrically connected; and wherein the antenna body corresponds to the through hole.

13 . The antenna fixing assembly of claim 1 , wherein the antenna module comprises:
a second antenna plate arranged on the first installation portion, wherein the second antenna plate is provided with an antenna body and an antenna circuit, the antenna body corresponds to a through hole, and one end of the antenna circuit is electrically connected to the antenna body; and an interface board provided with an interface circuit, wherein one end of the interface circuit is electrically connected to the antenna circuit, and an other end of the interface circuit is configured to be electrically connected to an external control unit.

14 . The antenna fixing assembly of claim 13 , wherein the installation bracket is provided with a second installation portion on a side away from the through hole, and the second installation portion provides an installation position of the interface board; and
wherein the interface board is detachably connected to the second installation portion.

15 . The antenna fixing assembly of claim 14 , wherein a limiting plate is arranged on the second installation portion, one end of the limiting plate is connected to the installation bracket, and an other end of the limiting plate extends away from a direction of the second installation portion; and
wherein opposite ends of the second installation portion are further provided with a second elastic buckle body, a second installation gap is formed between the second elastic buckle body and the end of the limiting plate, and the interface board is placed within the second installation gap.

16 . The antenna fixing assembly of claim 14 , wherein a second positioning structure is arranged between the installation bracket and the interface board, and the second positioning structure is configured to limit the installation position of the interface board on the second installation portion; and
wherein the second positioning structure comprises a second positioning pin and a second positioning hole, and the second positioning hole provides a positioning space for embedding the second positioning pin.
