[0029] Such as Figures 1 to 7As shown in the figure, an integrated vehicle-mounted camera fixing structure for a bumper provided in this embodiment includes a bumper body 1 and a camera fixing structure 2. Both the camera fixing structure 2 and the bumper body 1 are made of plastic, and their forming process is one-piece injection molding. A mounting hole 201 is provided at the center of the camera fixing structure 2. The mounting hole 201 is a circular hole for accommodating the lens 301 of the camera 3. The mounting hole 201 and the periphery of the lens 301 are in clearance fit. On the back of the camera fixing structure 2, an upper limiting rib 202, a lower limiting rib 203, a left limiting rib 204, and a right limiting rib 205 are respectively provided around the mounting hole 201. The upper limiting rib 202, the lower limiting rib 203, the left limiting rib 204, and the right limiting rib 205 cooperate to radially limit the outer shell of the camera 3. The upper limiting rib 202 and the lower limiting rib 203 are provided with limiting protrusions 206 on the side close to the mounting hole 201. The top surface of the limiting protrusion 206 contacts the surface of the upper housing 302 of the camera to limit the axial mounting position of the outer shell of the camera 3. On the back of the camera fixing structure 2, a left buckle 207 and a right buckle 208 are also provided on both sides of the mounting hole 201. The left buckle 207, the right buckle 208, and the limiting protrusion 206 jointly complete the axial limiting of the camera 3 to prevent axial movement. The ends of the left buckle 207 and the right buckle 208 are provided with left clamping blocks 2071 and right clamping blocks 2081 for fixing the camera 3. The clamping surface a of the left clamping block 2071 and the right clamping block 2081 in contact with the lower housing 303 of the camera is an inclined surface. The left clamping block 2071 and the right clamping block 2081 are in interference fit with the lower housing 303 of the camera, so that the left buckle 207 and the right buckle 208 can always contact the bottom surface of the lower housing 303 of the camera to compensate for the height tolerance of the camera 3 itself and ensure firm fastening.

[0030] Further, as Figure 2 shown in the figure, in this embodiment, a first indicating arrow 101 is provided on the bumper body 1 near the camera fixing structure 2. A second indicating arrow 3031 is provided on the lower housing 303 of the camera 3. The first indicating arrow 101 and the second indicating arrow 3031 cooperate to indicate the installation orientation of the camera 3. Or, an anti-fooling groove is provided on the upper housing 302 of the camera 3, and an anti-fooling protrusion is provided on the camera fixing structure 2 at a position opposite to the anti-fooling groove. The anti-fooling protrusion and the anti-fooling groove cooperate to achieve a better anti-fooling effect.

[0031] Further, in this embodiment, the clearance between the mounting hole 201 and the periphery of the lens 301 is controlled within 0.3 mm to 0.5 mm.

[0032] Furthermore, in this embodiment, the demoulding direction of the camera fixing structure 2 is consistent with the demoulding direction of the bumper body 1, and the angle between the demoulding direction of the bumper body 1 and the optical axis of the camera 3 is controlled between 0° and 30° to ensure smooth demoulding after integral injection molding.

[0033] Further, if Figure 3 , Figure 5 As shown, in this embodiment, the upper limit rib 202, the lower limit rib 203, the left limit rib 204, and the right limit rib 205 are all two. The two upper limit ribs 202 and the two lower limit ribs 203 are arranged near the left and right sides of the camera 3, and the two left limit ribs 204 and the right limit ribs 205 are arranged near the upper and lower ends of the camera 3. The left buckle 207 and the right buckle 208 are respectively arranged between the two left limit ribs 204 and the two right limit ribs 205.

[0034] Further, if Figure 5 As shown, in this embodiment, a left reinforcing rib 209 and a right reinforcing rib 210 are provided at the center position of the outer side of the left buckle 207 and the right buckle 208. The left reinforcing rib 209 and the right reinforcing rib 210 are used to strengthen the strength of the left buckle 207 and the right buckle 208 to avoid excessive deformation and ensure the camera fixing effect.

[0035] After adopting the above structure, the camera assembly method is as follows:

[0036] 1. Take the camera 3, and make the lens 301 of the camera face the assembly hole 201 of the camera fixing structure 2, and ensure that the second indication arrow 3031 on the bottom surface of the camera lower shell 303 is in the same direction as the first indication arrow 101 on the bumper body 1; or, make the foolproof groove on the surface of the camera upper shell 302 align with the foolproof protrusion on the camera fixing structure 2;

[0037] 2. Align the camera lens with the assembly hole 201, push it in along the limiting ribs around it, and deform the left buckle 207 and the right buckle 208 along both sides; when the top surface of the camera upper shell 302 contacts the limiting boss 206 at the bottom of the limiting rib, the left buckle 207 and the right buckle 208 simultaneously fix the bottom surface of the camera lower shell 303, completing the installation of the camera 3.

[0038] 3. When the camera 3 needs to be taken out, the left buckle 207 and the right buckle 208 are pushed to both sides by hand or with a tool until the left buckle 207 and the right buckle 208 are separated from the camera, and then the camera 3 is taken out axially backwards. The installation and disassembly are simple and convenient.

[0039] The above are the specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims.
