[0028] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0029] like Figures 1 to 4 As shown, the present invention provides an automotive camera assembly position correction mechanism, which can be detachably mounted on an assembly jig 100, and the assembly jig 100 is provided with an assembly platform 110 for placing an assembly product body 200, and the assembly product body 200 is provided with a second mounting hole 210 for mounting a camera 300, wherein the assembly platform 110 is provided with a first mounting hole 120 corresponding to the position of the second mounting hole 210, including:

[0030] The shell 400 is connected to the assembly jig 100 by threaded cooperation between the fastener and the connecting hole 130 on the assembly jig 100, wherein the shell 400 is provided with a through groove 411 coaxially arranged with the first mounting hole 120, and a guide pin 500 is installed in the through groove 411 coaxially arranged with the through groove 411 and movable along the axial direction of the through groove 411, and a guide portion 510 is provided on the guide pin 500, which passes through the first mounting hole 120 and protrudes from the assembly platform 110. When the camera 300 is installed, the coaxiality between the camera 300, the guide pin 500 and the second mounting hole 210 is achieved through the guide portion 510, and as the guide pin 500 moves axially, the camera 300 is inserted into the second mounting hole 210, completing the connection between the assembled product body 200 and the camera 300 to form an assembled product.

[0031] The present invention provides a vehicle camera assembly position correction mechanism, which completes the self-centering positioning installation of the camera 300 through the guide portion 510 on the guide pin 500, thereby equalizing the gap between the camera 300 and the second mounting hole 210 and improving the installation quality of the camera 300.

[0032] It is worth mentioning that when the assembled product body 200 is placed on the assembly platform 110, the plane where the guide portion 510 on the guide pin 500 in the correction mechanism is located is not lower than the plane where the second mounting hole 210 is located, wherein the coaxial setting between the second mounting hole 210 and the guide pin 500 is realized by the guide portion 510.

[0033] In this embodiment, the plane where the guide portion 510 is located is not lower than the plane where the second mounting hole 210 is located, so that when the camera 300 is assembled with the assembled product body 200, it first contacts the guide portion 510 on the guide pin 500, thereby realizing self-centering positioning of the camera 300 on the guide pin 500, and realizing the coaxial setting between the camera 300 and the guide pin 500. Then, as the camera 300 is pressed down, the guide pin 500 moves downward along the axial direction of the through groove 411, so that the guide portion 510 of the guide pin 500 exits the second mounting hole 210, and the camera 300 is gradually inserted into the second mounting hole 210. Since the camera 300 and the guide portion 510 are always in contact during this process, when the camera 300 is fully installed in the second mounting hole 210, a coaxial structure is formed between the second mounting hole 210 and the camera 300, thereby improving the reliability of the installation of the camera 300.

[0034] In addition, in this embodiment, the correction mechanism is modularized so that one correction mechanism can match a plurality of different assembly jigs 100 , thereby improving the versatility of the correction mechanism.

[0035] Preferably, the guide portion 510 includes a first guide conical surface 511 for achieving coaxial arrangement between the guide pin 500 and the second mounting hole 210, and a second guide conical surface 512 for achieving coaxial arrangement between the guide pin 500 and the camera 300, wherein the first guide conical surface 511 and the second guide conical surface 512 are coaxially arranged.

[0036] It is worth mentioning that a through hole 520 is provided on the guide pin 500 along the axial direction of the guide pin 500, and the guide portion 510 is provided at one end portion of the through hole 520, wherein the first guide conical surface 511 is located on the outer wall of the guide pin 500, and the second guide conical surface 512 is located on the hole wall of the through hole 520. When the assembled product body 200 is placed on the assembly platform 110, the first guide conical surface 511 and the second mounting hole 210 are plugged in and fitted together to realize self-centering of the area where the second mounting hole 210 on the assembled product body 200 is located, and the coaxial setting between the second mounting hole 210 and the guide pin 500 is completed; when the camera 300 contacts the guide pin 500, the second guide conical surface 512 realizes the self-centering positioning of the camera 300 on the guide pin 500, so that when the camera 300 is fully inserted into the second mounting hole 210, the coaxial setting between the camera 300 and the second mounting hole 210 is realized.
