[0022] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed at will, and the component layout may also be more complicated.

[0023] Example 1

[0024] like Figures 1 to 3 As shown, a car headlight detection device includes a base 1, and two guide rails 4 are arranged in parallel on the surface of the base 1. Preferably, the guide rails 4 are arranged as an I-section structure; sliders 5 are slidably arranged on the guide rails 4, and the two sliders 5 are connected by a connecting arm 6; a first electric push rod 3 is arranged on the surface of the base 1 in parallel with the guide rails 4, and the front end of the first electric push rod 3 is fixedly connected to the connecting arm 6; when the first electric push rod 3 works, the two sliders 5 move along the guide rails 4 driven by the connecting arm 6.

[0025] The longitudinal sliding assembly 7 is fixedly arranged on the upper surface of the connecting arm 6; further, in order to ensure the movement of the detection assembly 11 in the longitudinal direction, the longitudinal sliding assembly 7 includes a hollow body 71, and a sliding groove 75 is arranged on the upper part of the hollow body 71; preferably, the hollow body 71 is arranged as a hollow rectangular parallelepiped structure. A threaded rod 73 is rotatably arranged inside the hollow body 71, one end of the threaded rod 73 passes through the hollow body 71 and is connected to the output end of the motor 72; the other end of the threaded rod 73 passes through the hollow body 71 and is fixed by the bearing seat body; a sleeve 7601 is slidably arranged on the threaded rod 73, and a connecting piece 7602 is integrally arranged on the sleeve 7601, and the upper end of the connecting piece 7602 passes through the sliding groove 75 and is fixedly connected to the sliding seat 7603. L-shaped limiting protrusions 7604 are extended downward on both sides of the sliding seat 7603; guide grooves 74 are respectively provided on both sides of the hollow body 71; the L-shaped limiting protrusions 7604 are slidably engaged in the guide grooves 74. Under the action of the motor 72, the threaded rod 73 rotates at this time, and because the sleeve 7601 is integrally provided with a connecting piece 7602, under the cooperation of the connecting piece 7602 and the sliding groove 75, the sleeve 7601 drives the sliding seat 7603 to move along the length direction of the hollow body 71.

[0026] A second electric push rod 8 is fixedly provided on the upper surface of the longitudinal sliding component 7, and a mounting seat 9 is provided at the front end of the second electric push rod 8; a detection component 11 and a detection plate 10 are provided on the mounting seat 9, and the detection plate 10 is located at the rear side of the detection component 11; specifically, the mounting seat 9 is configured as a block, and in order to facilitate the installation of the detection component 11, a dovetail groove is provided on the block, and a dovetail groove protrusion is provided at the bottom of the detection component 11, and the protrusion is embedded in the groove. In this solution, the detection component 11 is specifically a car light detector, which can be any one of SV-D1T SV-D2T SV-D5T SV-D6TSVQD-100C SVQD-200A SVQD-300A, and is used to detect the luminous intensity and light beam irradiation position (i.e., the optical axis offset) of the motor vehicle headlight.

[0027] In order to achieve height adjustment, a second electric push rod 8 is fixedly provided on the upper surface of the longitudinal sliding assembly 7 .
