[0019] 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.

[0020] Please see Figs. 1-3 This utility model provides a technical solution: a testing device for the sealing and waterproofing of vehicle lights, including a base 1, a first support frame 2 fixedly installed on the top of the base 1, a first cylinder 3 arranged on the top of the first support frame 2, a limiting plate 4 provided at the end of the cylinder rod of the first cylinder 3, a waterproof battery 5 arranged on the top of the base 1, and two sets of first cylinders 3 extending their cylinder rods inward, thereby clamping the waterproof battery 5 of the first support frame 2 through the limiting plate 4, waiting for the assembly of the vehicle light 14. The waterproof battery 5 is designed with a quick-release structure, and the vehicle light 14 can be started by pressing the vehicle light 14 on the waterproof battery 5, and the connection is waterproof and will not fall off.

[0021] A guide rail 6 is fixedly installed above the base 1. A telescopic mechanism 7 is installed on the front side of the guide rail 6. A second support frame 8 is fixedly installed at the extended end of the telescopic mechanism 7. A first connecting rod 10 is connected to the bottom bearing of the second support frame 8. A second connecting rod 11 is connected to the left end bearing of the first connecting rod 10. A clamping plate 12 is slidably connected to the second support frame 8. The right side of the clamping plate 12 is connected to the second connecting rod 11 by a bearing. A second cylinder 9 is connected to the bottom bearing of the second support frame 8. The rod end of the second cylinder 9 is connected to the right side bearing of the second connecting rod 11. The telescopic mechanism 7 can slide left and right on the guide rail 6 and extend and retract the internal telescopic rod to drive the second support frame 8 to rise and fall, thereby transferring the vehicle light 14. After the worker places the vehicle light 14 in the designated area, it waits to be clamped. When the second cylinder 9 extends its rod, it will drive the connection between the first connecting rod 10 and the second connecting rod 11 to move together, thereby changing the original bent state to a flat state. This process will push the clamping plate 12 to move towards the center of the second support frame 8 to achieve the clamping effect.

[0022] A support head 13 is provided on the inner side of the clamping plate 12, and a second set of clamping mechanisms 24 is provided at the bottom of the second support frame 8. The inner side of the support head 13 clamps the vehicle lamp 14, and a water tank 15 is provided above the base 1. The second set of clamping mechanisms 24 is similar to the above. The support heads 13 at both ends will clamp the vehicle lamp 14, thereby achieving the clamping effect while reducing the contact area and preventing the sealing test from being affected. Then, the telescopic machine 7 slides above the water tank 15 and drives the vehicle lamp 14 to be immersed in the water tank 15 through the telescopic rod, thereby realizing the water immersion test of the vehicle lamp 14, increasing the water pressure at the sealing point to achieve the effect of rapid detection. If the vehicle lamp 14 goes out, it means that the sealing performance is unqualified.

[0023] A push rod motor 16 is installed above the base 1. A controller 17 is installed at the output end of the push rod motor 16. A control chamber 18 is installed inside the controller 17. A gear 19 is connected to the bearing inside the control chamber 18. A rack 20 is installed above the base 1. The rack 20 and the gear 19 are meshed together. The control chamber 18 and the rack 20 are slidably connected. The push rod motor 16 can extend its internal output rod, thereby driving the control chamber 18 to move to the right. During this process, the gear 19 inside the control chamber 18 will be driven to rotate by the rack 20, thereby driving the upper support platform 25 to rotate.

[0024] A support platform 25 is fixedly installed above the gear 19. A protective plate 21 is provided on the outside of the support platform 25, and a third cylinder 22 is provided on the inside of the protective plate 21. A fixing groove 23 is provided at the end of the rod of the third cylinder 22. After the headlight 14 is submerged in water, it will be transported to the first support frame 2 for the removal of the waterproof battery 5. Then, the headlight 14 will be placed on the support platform 25. After that, the clamping assembly will be removed, and the third cylinder 22 will extend its rod to drive the fixing groove 23 to move inward, thereby fixing the headlight 14. Then, the push rod motor 16 will be started. Since the rear end of the support platform 25 is fixed to the gear 19, the support platform 25 will rotate rapidly with the gear 19. The push rod motor 16 will quickly extend and retract the output rod. After the headlight 14 rotates rapidly, if water leaks into the headlight 14 through the seal, the water droplets inside will be thrown to the front of the headlight 14 due to inertia. The staff needs to observe whether there are water droplets gathered inside the headlight 14 by centrifugal force, so as to quickly determine whether the waterproof seal is qualified and improve the testing efficiency.
