[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

A sliding plate 12 with one end extending into the sliding groove 11 is fixedly connected to the bottom surface of the cover plate 2. A connecting plate 9 is fixedly connected inside the sliding groove 11. A drive motor 13 is fixedly installed inside the sliding groove 11. A screw 10 with one end passing through the sliding plate 12 and extending to the connecting plate 9 is fixedly connected to the output shaft of the drive motor 13.

[0028] The placement chamber 1 is a cuboid with a hollow interior and a missing top surface. The limiting rod 6 and the limiting hole 5 are fitted with a clearance. The sliding plate 12 is an L-shaped plate. The sliding plate 12 and the sliding groove 11 are slidably connected. The screw 10 is rotatably connected to the connecting plate 9 through the bearing. The bottom surface of the sliding plate 12 has a threaded hole. The screw 10 passes through the threaded hole and is threadedly connected to it.

[0029] Specifically, water enters the interior of the placement chamber 1, and the drive motor 13 is started. The output end of the drive motor 13 drives the screw 10 to rotate. Through the threaded connection between the screw 10 and the sliding plate 12 and the sliding connection between the sliding plate 12 and the sliding groove 11, the screw 10 drives the cover plate 2 to move downward through the sliding plate 12, so that the cover plate 2 fits with the placement chamber 1, allowing the car light to enter the interior of the placement chamber 1. The liquid is used to perform a sealing test on the car light. The gap fit between the limiting rod 6 and the limiting hole 5 supports the cover plate 2, improving the stability of the cover plate 2. The interior of the placement chamber 1 is observed through the glass plate 4 to see if any bubbles are generated.

[0030] Please see Figures 1 to 3 In this embodiment, the cover plate 2 is provided with a fixing assembly for fixing the vehicle lights. The fixing assembly includes a mounting bracket 7, which is fixedly connected to the bottom surface of the cover plate 2 and extends into the interior of the placement compartment 1. Telescopic rods 16 are fixedly connected to the left and right inner walls of the mounting bracket 7. Clamping plates 20 are fixedly connected to the opposite sides of the two telescopic rods 16. Springs 17, which are fixedly connected to the mounting bracket 7 and clamping plates 20 respectively, are fitted on the outer peripheral walls of the two telescopic rods 16. Two support grooves 18 are opened in the inner bottom wall of the mounting bracket 7. A support plate 19 with one end extending into the interior of the support groove 18 is fixedly connected to the bottom surface of the two clamping plates 20. Two electric push rods 3 are fixedly installed on the top surface of the cover plate 2. The output ends of the two electric push rods 3 penetrate the cover plate 2 and extend into the interior of the mounting bracket 7. A pressure plate 8 is fixedly connected between the output ends of the two electric push rods 3.

[0031] Among them, the support plate 19 and the support groove 18 are slidably connected, the pressure plate 8 is located on the top of the clamping plate 20, the top surface of the cover plate 2 has two through holes, the output end of the electric push rod 3 passes through the through holes and is fitted with them with clearance, the telescopic rod 16 is composed of a sleeve and a moving rod, one end of the moving rod passes through and extends into the inside of the sleeve, the outer side of the moving rod is fixedly connected to a limiting block located inside the sleeve, and a through hole adapted to the moving rod is opened on one side of the sleeve.

[0032] Specifically, pulling the clamp 20 causes it to move, compressing the telescopic rod 16 and spring 17, causing them to retract. The sliding connection between the support plate 19 and the support groove 18 supports the clamp 20, improving its stability. The headlight is placed between the two clamps 20. Releasing the clamps 20 allows the spring 17 to push them back to their original position, fixing them in place. The electric push rod 3 is then activated, its output driving the pressure plate 8 downwards, bringing it into contact with the headlight and restricting its movement.

[0033] It should be noted that the electric actuator 3 is a conventional device known in the prior art, and its specific structure and working principle will not be described in detail here. This application can ensure that the output ends of the two electric actuators 3 extend and retract simultaneously by using a synchronization controller or other synchronization device, thereby achieving synchronous operation. These synchronization devices are common and mature in the field of electric control, so they will not be described in detail in the specific embodiments.

[0034] Please see Figures 1 to 3 In this embodiment, the placement chamber 1 is equipped with a conveying assembly for conveying liquid. The conveying assembly includes a booster pump 21, which is fixedly installed on the back of the placement chamber 1. A water inlet pipe 22 is fixedly installed at the water inlet end of the booster pump 21, which extends through the placement chamber 1 and into its interior. A water outlet pipe 23 is fixedly installed at the water outlet end of the booster pump 21, which extends through the placement chamber 1 and into its interior. A drain pipe 14 is fixedly connected to the inner bottom wall of the placement chamber 1, which extends through the placement chamber 1 and into its left side.

[0035] The inlet pipe 22 and outlet pipe 23 are both fixedly connected to the placement chamber 1, and the drain pipe 14 is an L-shaped pipe.

[0036] Specifically, the booster pump 21 is started, and the liquid is pumped through the inlet pipe 22 and the outlet pipe 23. The booster pump 21 pressurizes the liquid. When it is necessary to discharge the water, the solenoid valve 15 is started, and the liquid is discharged through the drain pipe 14.

[0037] It should be noted that both the solenoid valve 15 and the booster pump 21 are conventional devices known to the public in the prior art, and their specific structures and working principles will not be described in detail in this article.

[0038] The working principle of the above embodiments is as follows:

[0039] Water enters the placement chamber 1, pulling the clamp 20 and causing it to move, compressing the telescopic rod 16 and spring 17. The headlight is placed between the two clamps 20. The clamps 20 are released, and the spring 17 pushes them back to their original position, fixing them to the headlight. The electric push rod 3 is activated, its output driving the pressure plate 8 downwards, bringing it into contact with the headlight and restricting its movement. The drive motor 13 is activated, its output driving the screw 10 to rotate, through the threaded connection between the screw 10 and the sliding plate 12. The sliding connection between the sliding plate 12 and the sliding groove 11 allows the screw 10 to drive the cover plate 2 downward through the sliding plate 12, so that the cover plate 2 and the placement chamber 1 are in contact, allowing the car light to enter the interior of the placement chamber 1. The car light is sealed by liquid, and the interior of the placement chamber 1 is observed through the glass plate 4 to see if any air bubbles are generated. The booster pump 21 is started, and the liquid is pumped through the water inlet pipe 22 and the water outlet pipe 23. The booster pump 21 pressurizes the liquid. When it is necessary to drain the water, the solenoid valve 15 is started, and the liquid is drained through the drain pipe 14.
