[0030] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0031] like Figure 1 to Figure 4As shown, a vehicle-mounted camera comprises a holder bracket 10 with a lens 13 installed, a back cover 20 inserted and matched with the end of the holder bracket 10 away from the lens 13, and a bracket 30 mounted on the end of the back cover 20 facing away from the holder bracket 10, which are arranged in sequence. A PCB board 40 is installed in a chamber formed by the back cover 20 and the holder bracket 10. At least one locking rivet column 11 is protruded on the bottom wall of the holder bracket 10 facing the back cover 20, and a socket 41 for the locking rivet column 11 to be connected through the hole is opened on the PCB board 40. The column end of the locking rivet column 11 passing through the socket 41 on the PCB board 40 is formed by stamping to form a locking rivet head 111, and the locking rivet head 111 forms a contact pressure with the edge of the socket 41 to lock the PCB board 40 and install it on the holder bracket 10.

[0032] The structures of the various components of the utility model are described below.

[0033] like Figure 2 and Figure 3 As shown, in this embodiment, the number of locking rivet posts 11 on the holder bracket 10 is two for example, and the two locking rivet posts 11 are located at the top corners of the holder bracket 10, and the line between the axes of the two constitutes the diagonal line of the holder bracket 10. The sockets 41 on the PCB board 40 correspond to the locking rivet posts 11 and are arranged in alignment; such a design increases the effective installation area of ​​the PCB board 40 on the holder bracket 10, thereby increasing the installation stability of the PCB board 40. Of course, in other embodiments, locking rivet posts 11 can also be set at the three top corners or four top corners of the end face of the holder bracket 10, and the corresponding setting positions and numbers of the sockets 41 on the PCB board 40 also need to be adaptively adjusted to achieve the effect of enhancing the installation stability of the PCB board 40.

[0034] In the actual riveting process, when the stamping equipment (not shown) stamps the locking rivet head 111 at the end of the locking rivet column 11, the corresponding stress will also be loaded on the PCB board 40, causing problems such as damage to the structure of the PCB board 40.

[0035] like Figure 3 and Figure 5As shown, in order to solve the above problems, this embodiment adopts the following solution: the diameter of the locking rivet column 11 is r, the diameter of one of the plug holes 41 on the PCB board 40 is α, and the diameter of the other plug hole 41 is β, α:r=1.58:1.5, β:r=2.08:1.5. With such a design, when the plug hole 41 on the PCB board 40 is inserted into the locking rivet column 11 to achieve pre-positioning, there is a gap between the hole wall of the plug hole 41 and the surrounding side of the locking rivet column 11, so that during stamping, the stress transmitted to the locking rivet column 11 by the stamping equipment will not directly act on the PCB board 40, effectively avoiding the situation that the PCB board 40 may be damaged during the stamping process, and improving the safety of the installation process; after many experiments and tests, the inventor found that when the stamping speed is 10mm / min and the stamping pressure is 80N, the stress has the least effect on the PCB board 40 when the locking rivet head 111 is stamped at the end of the locking rivet column 11.

[0036] like Figure 1 to Figure 3 As shown, a baffle cover 12 is provided around the end of the holder bracket 10 facing away from the lens 13, and a receiving groove 101 for receiving the PCB board 40 is formed between the holder bracket 10 and the baffle cover 12. A stepped groove 201 for the baffle cover 12 to be inserted and matched is provided around the end surface of the rear cover 20. When the holder bracket 10 and the rear cover 20 are inserted and matched together, a contact pressure is formed between the outer end surface of the baffle cover 12 and the bottom of the stepped groove 201. At this time, the two are fixedly connected together by laser welding. Of course, in other embodiments, other sealing and fixing methods such as gluing can also be used to fix the two.

[0037] like Figure 1 and Figure 4 , Figure 5 As shown, a plurality of mounting rivet columns 21 are protruded on the rear end surface of the rear cover 20, and a mounting hole 301 which is arranged in alignment with the mounting rivet column 21 and for connecting the mounting rivet column 21 through the hole is opened on the bracket 30, and the column head end of the mounting rivet column 21 passing through the mounting hole 301 is formed by stamping to form a mounting rivet head 211 which presses the bracket 30 to be mounted on the rear cover 20.

[0038] like Figure 1 and Figure 4 , Figure 5 As shown, there are two rivet studs 21 installed on the back cover 20, the two rivet studs 21 are located at the top corners of the back cover 20, and the line between the two axes constitutes the diagonal of the back cover 20, and the mounting holes 301 on the bracket 30 correspond to the mounting rivet studs 21 on the back cover 20 and are arranged in alignment.

[0039] It should be noted here that the present application adopts stamping to complete the fixed connection between the PCB board 40 and the holder bracket 10, and the fixed connection between the bracket 30 and the back cover 20, and the fixed connection between the back cover 20 and the holder bracket is achieved by laser welding, so that the finally assembled vehicle-mounted camera product has a small product volume and is lightweight and miniaturized.

[0040] 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.
