The photographing mechanism 5 further includes a second fixing plate 53 fixed on the first fixing plate 52, a third fixing plate 54 fixed on the second fixing plate 53, and a fourth fixing plate 55 arranged on the third fixing plate 54. The two cameras 50 are fixedly connected to the fourth fixing plate 55 correspondingly.

[0039] In this embodiment, the two fixing rods 51 are arranged in parallel and are connected to a side wall of the closed box 4 by screws. The two first fixing plates 52 are arranged in parallel and are both connected to the two fixing rods 51 by screws. The fixing rods 51 are provided with a number of uniformly arranged screw holes, and the user can select the installation position of the first fixing plate 52 in the vertical direction according to needs. The first fixing plate 52 is also provided with a number of uniformly arranged screw holes, and the user can select the installation position of the second fixing plate 53 in the horizontal direction according to needs.

[0040] In addition, a first fixing hole 540 and an arc-shaped first arc groove 541 are formed on the third fixing plate 54, and a second fixing hole 550 and an arc-shaped second arc groove 551 are formed on the fourth fixing plate 55. The third fixing plate 54 is connected to the second fixing plate 53 by screws passing through the first fixing hole 540 and the first arc groove 541. The fourth fixing plate 55 is connected to the third fixing plate 54 by screws passing through the second fixing hole 550 and the second arc groove 551. When installing the third fixing plate 54, the user can first install the screws at the first fixing hole 540, rotate the third fixing plate 54 around the axis of the first fixing hole 540 according to needs, and then install the screws at the first arc groove 541 to adjust the angle of the third fixing plate 54. Similarly, the angle of the fourth fixing plate 55 can be adjusted to adjust the angle of the camera 50 according to needs. In addition, since the overall size of the vehicle lamp 1 is large, in this embodiment, two cameras 50 are used to simultaneously take test photos from different angles and send the test photos to the host computer 3. After being synthesized by the host computer 3, they are compared with the standard photos, so that the occupied area of the photographing mechanism 5 is small, making the overall equipment compact.

[0041] In this embodiment, the closed box 4 further includes a folding door 40 and a second driving member 41. One end of the folding door 40 is fixedly connected to the first side plate 42 that forms the closed box 4, and the other end is fixedly connected to the output end of the second driving member 41. The second driving member 41 can drive the folding door 40 to open or close, facilitating the installation of the vehicle lamp 1 and providing a closed test environment.

[0042] In use, the folding door 40 is in the open state and the clamping mechanism 6 is in the extended state. The user places the vehicle lamp 1 on the first fixed platform 60 and presses the wrench 662. The wrench 662 rotates clockwise around the first rotating shaft 71, thereby pushing the connecting rod 663, and then pushing the telescopic rod 664 to extend along the sliding groove 74. Finally, the abutting member 665 is pushed forward, and finally the vehicle lamp 1 is fixed between the abutting member 665 and the first abutting block 61. Then the user manually plugs the wire harness of the vehicle lamp 1 into the connector to connect the vehicle lamp 1 to the host computer 3. A dual-control start button 9 electrically connected to the controller 20 is also provided on the vehicle lamp function testing device. After the user presses the dual-control start button 9, the controller 20 starts the first driving member 670 to drive the first fixed platform 60 to retract into the closed box 4. Then the controller 20 starts the second driving member 41 to close the folding door 40. The host computer 3 controls the vehicle lamp 1 to light up. When the vehicle lamp 1 lights up, the host computer 3 controls the two cameras 50 to simultaneously take test photos from different angles and send the test photos to the host computer 3. After being synthesized by the host computer 3, they are compared with the standard photos. When the test passes, the word "PASS" is displayed on the display screen of the host computer 3. If it fails, the word "FALL" is displayed. Finally, the host computer 3 controls the vehicle lamp 1 to turn off. The controller 20 starts the second driving member 41 to open the folding door 40. Then the controller 20 starts the first driving member 670 to drive the first fixed platform 60 to extend, removes the vehicle lamp 1, and starts the next round of testing.
