[0033] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0034] like Figure 1 and Figure 2 As shown, a vehicle-mounted camera with a PCB board quick-install structure includes a holder bracket 10 with a lens 11 installed at the front end, a back cover 20 snap-fitted to the rear end of the holder bracket 10, and a bracket 30 attached to the rear end of the back cover 20, which are arranged in sequence. The PCB board 40 is installed in a cavity 100 formed by the snap connection between the back cover 20 and the holder bracket 10; the end surface of the holder bracket 10 is convexly provided with at least two mounting columns 12 located in the cavity 100, and the end surface of the mounting column 12 is bonded with a glue structure 50 for bonding and fixing the side surface of the PCB board 40.

[0035] The structures of the various components of the utility model are described below.

[0036] like Figure 2 and Figure 3 As shown, the adhesive structure 50 has a bottom plate adhesive 51 bonded to the end surface of the mounting column 12 and a side plate adhesive 52 protruding from the bottom plate adhesive 51 away from the bonding surface. The side plate adhesive 52 faces the central axis side of the holder bracket 10 and has a snap-fit ​​groove 521 for snapping and bonding at the corner of the end surface of the PCB board 40.

[0037] In this embodiment, the adhesive surface of the holder bracket 10 is pre-treated to increase the roughness of the adhesive surface between the mounting column 12 and the base plate, thereby enhancing the positive stress strength of the adhesive structure 50 and the holder bracket. It should be noted here that curing glue or UV glue can be used as the adhesive structure 50. In other embodiments, adhesive materials of other materials can also be used according to the fixing strength required by the PCB board 40, including but not limited to the two adhesive materials listed above.

[0038] like Figure 2 and Figure 3As shown, a tooth structure 41 is formed at four corners of the end face of the PCB board 40, and the tooth structure 41 includes a plurality of teeth 411 arranged in succession; the snap-fit ​​groove 521 on the side plate adhesive 52 is a tooth groove structure adapted to the tooth structure 41 for engagement and bonding. Such a design can increase the adhesive area between the side edge of the PCB board 40 and the side of the adhesive structure 50, and improve the adhesive shear strength of the adhesive structure 50 to the PCB board 40; the tooth 411 structure in the diagram of this embodiment takes an arch bridge-shaped arc structure as an example, and in other embodiments, the tooth 411 of a triangular, trapezoidal or other structure can also be used.

[0039] like Figure 2 and Figure 3 As shown, the number of mounting columns 12 on the end face of the holder bracket 10 is four as an example, and the four mounting columns 12 are respectively located at the top corners of the end face of the holder bracket 10. In other embodiments, only two or three mounting columns 12 may be used, and there is no limitation on the setting position of the mounting columns 12 on the end face of the holder bracket 10. It should be noted here that when two mounting columns 12 are used, the two mounting columns 12 are set at the diagonal position of the end face of the holder bracket 10, which has the best fixing effect on the PCB board 40.

[0040] like Figure 2 and Figure 3 As shown, the end surface of the mounting column 12 is convexly formed with a rib 121 for the side panel adhesive 52 to be bonded away from the side enclosure of the snap-fit ​​groove 521. With such a design, the rib 121 can support the enclosure of the side panel adhesive 52 of the adhesive structure 50, which not only improves the installation stability of the adhesive structure 50, but also can simultaneously improve the installation stability of the PCB board 40, greatly reducing the possibility of the PCB board 40 being separated from the mounting column 12. It is worth noting that the contact part between the PCB board 40 and the bottom plate adhesive 51 and the side plate adhesive 52 of the adhesive structure 50 is the base material part that is not attached with green oil. Compared with the part attached with green oil, the surface of the base material part of the PCB board 40 is rougher, which can enhance the adhesion of the adhesive structure 50, so that the PCB board 40 can be more firmly installed in the holder bracket 10.

[0041] like Figure 2 and Figure 4 As shown, a cover frame 21 is provided on the end face of the rear cover 20 or the end face of the holder bracket 10, and a stepped groove 101 for the cover frame 21 to be buckled is formed correspondingly on the end face of the holder bracket 10 or the end face of the rear cover 20; when the holder bracket 10 is buckled with the rear cover 20, the mounting column 12 extends into the inner cavity 211 of the holder bracket 10, and the outer edge of the inner cavity 211 of the cover frame 21 and the bottom of the stepped groove 101 form a contact pressure, and at this time the two are fixedly connected together by laser welding. Of course, in other embodiments, other sealing fixing methods such as gluing can also be used to fix the two.

[0042] like Figure 4 As shown, a plurality of rivet posts 22 are protruded on the rear end surface of the back cover 20, and a through hole 301 is opened on the bracket 30 to be aligned with the rivet post 22 and for the rivet post 22 to be connected through the hole. The head end of the rivet post 22 passing through the through hole 301 is pressed together to form a rivet head 23 that presses the bracket 30 to be mounted on the back cover 20.

[0043] It should be noted here that the present application adopts an adhesive method to fix the PCB board 40 and the holder bracket 10, adopts a stamping method to complete the fixed connection between the bracket 30 and the back cover 20, and the back cover 20 and the holder bracket are fixedly connected by laser welding, so that the finally assembled vehicle-mounted camera product has a small product volume and is lightweight and miniaturized.

[0044] Another embodiment of the present application:

[0045] like Figure 5 to Figure 7 As shown, the end surface of the holder bracket 10 is raised to form a mounting boss 13 which is flush with the end surface of the mounting column 12 and is corresponding to the side of the PCB board 40. The glue structure 50 is a side glue 53 located between the side of the PCB board 40 and the inner wall of the cover frame 21 on the holder bracket 10. The side glue 53 is glued and fixed to the end surface of the mounting boss 13 facing the lens 11. The left and right sides of the side glue 50 are respectively glued and fixed to the side of the PCB board 40 and the inner wall of the cover frame 21 on the holder bracket 10, thereby gluing and fixing the PCB board 40 to the holder bracket 10.

[0046] like Figure 5 to Figure 7 As shown, there are two mounting posts 12, and the two mounting posts 12 are diagonally arranged on the end face of the holder bracket 10; a positioning post 122 is vertically fixed on the end face of the mounting post 12, and a positioning hole 401 for the positioning post 122 to be connected through the hole is opened on the PCB board 40. When the positioning hole 401 on the PCB board 40 is buckled into the positioning post 122, the PCB board 40 is in a preset bonding position. Such a design can accurately locate the installation position of the PCB board 40, and also improve the installation stability of the PCB board 40.

[0047] The above embodiments are only used to illustrate the present invention, not to limit the present invention. A person skilled in the art may make various changes or modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions should also fall within the scope of the present invention and be defined by the claims.
