Description
Technical Field
[0001] This utility model relates to the field of vehicle lamp testing technology, specifically a simulation device for testing the waterproofness of vehicle lamps. Background Technology
[0002] Automotive headlight waterproofing testing involves a series of tests to verify the performance of headlights under various waterproof conditions, ensuring they function properly in humid or rainy weather. The main purpose of waterproofing testing is to detect the waterproof and water-resistant properties of the headlights, ensuring they can operate normally in wet or rainy conditions and preventing moisture or water ingress into the headlights, thus avoiding fogging inside the headlights.
[0003] Existing automotive headlight waterproofing tests simulate rainwater spraying, but this simple spraying cannot simulate harsh road conditions, resulting in an inaccurate sealing test that cannot guarantee that the headlights of road test vehicles will have the same waterproof sealing performance as those in the simulation chamber when encountering rain or snow.
[0004] Therefore, it is necessary to design a simulation device that is both practical and comprehensive for testing the waterproofness of vehicle lights. Utility Model Content
[0005] The purpose of this invention is to provide a simulation device for testing the waterproofness of vehicle lights, in order to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a simulation device for testing the waterproofness of vehicle lights, comprising a base, a motor fixedly mounted on the top of the base, a piston cylinder fixedly mounted on the left side of the motor, a camshaft connected to the internal bearing of the piston cylinder, the camshaft being fixedly connected to the output end of the motor, a connecting rod connected to the inner bearing of the camshaft, a sliding rod connected to the lower bearing of the connecting rod, the sliding rod being slidably connected to the piston cylinder, and a support frame provided at the bottom of the sliding rod.
[0007] According to the above technical solution, a support plate is provided on the inner side of the support frame, an adsorber is provided on the inner side of the support frame, a vehicle light is adsorbed on the inner side of the adsorber, and a buffer is provided above the base.
[0008] According to the above technical solution, a detection chamber is fixedly installed above the base, a slide groove is provided above the detection chamber, a slider is slidably connected inside the slide groove, a threaded rod is connected to the bearing inside the slide groove, the threaded rod is threadedly engaged with the slider, and the left end of the threaded rod is connected to the shaft of the camshaft.
[0009] According to the above technical solution, a conveying pipe is provided at the bottom of the slider, a sprayer is rotatably connected to the lower end of the conveying pipe, a support pipe is provided at the rear side of the conveying pipe, and the support pipe is slidably connected to the detection chamber.
[0010] According to the above technical solution, a conversion cylinder is fixedly installed on the top of the base. An air compressor is provided at the air inlet end of the conversion cylinder. The compression end of the air compressor is connected to the support frame. A water tank is provided at the air outlet end of the conversion cylinder. A hose is provided at the water outlet end of the water tank. The other end of the hose is connected to the support pipe.
[0011] Compared with the prior art, the beneficial effects achieved by this utility model are:
[0012] (1) By setting a camshaft, after the motor starts, the output shaft can drive the camshaft to rotate, so that it rotates in the piston cylinder, thereby driving the slide rod to slide up and down in the piston cylinder through the connecting rod. The slide rod will drive the support frame to slide up and down, simulating the up and down bumping effect of a car driving on the road.
[0013] (2) A threaded rod is provided, and a sliding door is provided on the front side of the test chamber. After the vehicle lights are installed, the staff closes the sliding door to observe. After the motor starts, the threaded rod will rotate with the output shaft. During the rotation, the slider that meshes with it will be driven to slide to the right due to its sliding connection with the slide groove. When the slider slides to the rightmost side of the slide groove, the motor will stop and reverse until the slider reaches the leftmost side, and then resume forward rotation, thereby achieving the effect of the slider sliding left and right on the slide groove.
[0014] (3) By setting up an air pump, when the support frame moves up and down, it will drive the air pump to pump air into the conversion cylinder and transmit the gas to the water tank. After the water tank is filled with air, the water inside will be transported to the support pipe through the hose, thereby realizing the synchronous start of water spraying, vibration simulation, and rain water front and back flushing simulation after the motor starts, fully simulating various situations, with good practicality and good detection effect.

Detailed Implementation
[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 Figure 1-3 This utility model provides a technical solution: a simulation device for testing the waterproofness of vehicle lights, including a base 1, a motor 2 fixedly installed on the top of the base 1, a piston cylinder 3 fixedly installed on the left side of the motor 2, a camshaft 4 connected to the internal bearing of the piston cylinder 3, the camshaft 4 being fixedly connected to the output end of the motor 2, a connecting rod 5 connected to the inner bearing of the camshaft 4, a sliding rod 6 connected to the lower bearing of the connecting rod 5, the sliding rod 6 being slidably connected to the piston cylinder 3, and a support frame 7 being provided at the bottom of the sliding rod 6. After the motor 2 is started, it can drive the camshaft 4 to rotate through the output shaft, causing it to rotate inside the piston cylinder 3, thereby driving the sliding rod 6 to slide up and down inside the piston cylinder 3 through the connecting rod 5. The sliding rod 6 will drive the support frame 7 to slide up and down, simulating the up and down bumping effect of a car driving on the road.
[0021] A support plate 10 is provided on the inner side of the support frame 7, and an adsorber 8 is provided on the inner side of the support frame 7. The vehicle light 9 is adsorbed on the inner side of the adsorber 8. A buffer 11 is provided above the base 1. The worker places the vehicle light 9 on the support plate 10 and then starts the adsorber 8. The adsorber 8 will use the suction cup to adhere and fix the vehicle light 9 to prevent it from falling. When the support frame 7 slides up and down, the vehicle light 9 will move up and down together to simulate bumps. At the same time, the buffer 11 will buffer the movement to prevent the vehicle light 9 from being damaged due to excessive vibration when it touches the bottom multiple times during the shaking process.
[0022] A detection chamber 12 is fixedly installed on the top of the base 1. A slide groove 13 is provided on the top of the detection chamber 12. A slider 14 is slidably connected inside the slide groove 13. A threaded rod 15 is connected to the bearing inside the slide groove 13. The threaded rod 15 is threadedly engaged with the slider 14. The left end of the threaded rod 15 is connected to the shaft of the camshaft 4. A sliding door is provided on the front side of the detection chamber 12. After the headlight 9 is installed, the staff closes the sliding door for observation. After the motor 2 is started, the threaded rod 15 will rotate with the output shaft. During the rotation, the slider 14, which is engaged with it, will be driven to slide to the right due to its slidable connection with the slide groove 13. When the slider 14 slides to the rightmost side of the slide groove 13, the motor 2 will stop and reverse until the slider 14 reaches the leftmost side, and then resume forward rotation, thereby achieving the effect of the slider 14 sliding left and right on the slide groove 13.
[0023] A conveying pipe 16 is provided at the bottom of the slider 14. A sprayer 17 is rotatably connected to the lower end of the conveying pipe 16. A support pipe 18 is provided at the rear side of the conveying pipe 16. The support pipe 18 is slidably connected to the detection chamber 12. When the slider 14 slides left and right on the slide groove 13, the support pipe 18 transports water to the conveying pipe 16 and then sprays it out through the sprayer 17. The sprayer 17 will rotate when spraying water, so as to conduct water spraying experiments on the vehicle headlight 9 from multiple angles, simulate the rain effect under different conditions, and improve the detection efficiency.
[0024] A conversion cylinder 22 is fixedly installed on the top of the base 1. An air pump 21 is provided at the air inlet end of the conversion cylinder 22. The compression end of the air pump 21 is connected to the support frame 7. A water tank 20 is provided at the air outlet end of the conversion cylinder 22. A hose 19 is provided at the water outlet end of the water tank 20. The other end of the hose 19 is connected to the support pipe 18. When the support frame 7 moves up and down, it will drive the air pump 21 to pump air into the conversion cylinder 22 and transmit the air to the water tank 20. After the water tank 20 is inflated, it will transport the water inside through the hose 19 to the support pipe 18. This realizes the synchronous start of water spraying, vibration simulation, and rain rinsing simulation after the motor 2 starts. It fully simulates various situations, has good practicality, and good testing effect.
