[0004] The purpose of this invention is to provide a simulated rain test device for endurance testing of automotive parts, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A simulated rain test device for endurance testing of automotive parts includes a test bench, a spray mechanism on the outer wall of the test bench, an adjustment motor installed on the front of the test bench, a controller installed on the outer wall of the test bench, a drain pipe installed at the center of the front of the test bench, and terminal blocks installed on the outer wall of the test bench.

[0007] The spraying mechanism includes an adjusting frame rotatably connected to the top of the test bench. A connecting rod is fixedly connected to the center of the bottom of the adjusting frame. A rotating plate is rotatably connected to the bottom of the connecting rod. A guide pipe is fixedly connected to the bottom of the rotating plate and below the connecting rod. A traction rope is fixedly connected to the top of the guide pipe and on both sides of the connecting rod. A winding shaft is fixedly connected to the outer wall of the traction rope and inside the adjusting frame. A winding motor is fixedly connected to the outer wall of the winding shaft. A spray head is fixedly connected to the bottom of the guide pipe. A connecting pipe is fixedly connected to the top of the guide pipe and near the traction rope. A water inlet sleeve is fixedly connected to the inside of the adjusting frame and directly above the connecting pipe. A worm gear is fixedly connected to the outer wall of the adjusting frame and inside the test bench. A worm is meshed with the bottom of the worm gear.

[0008] As a preferred embodiment of this utility model, the test bench is made of aluminum alloy, and the connection method of the adjusting motor, terminal block and controller is electrical connection.

[0009] As a preferred embodiment of this utility model, the adjusting frame, connecting rod, and water inlet sleeve are all made of aluminum alloy. The adjusting frame has an arched structure design, and the winding shaft is connected to the adjusting frame, and the worm gear is connected to the test bench by rotation.

[0010] As a preferred embodiment of this utility model, the traction rope is made of nylon rope, and two sets of the traction rope, winding shaft, worm gear, worm wheel and winding motor are provided. The connection between the traction rope and the adjustment frame is a sliding connection.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model designs a simulated rain test device for endurance testing of automotive parts. The device utilizes a spray mechanism to conduct rain tests on the parts. The parts are fixedly placed on a test bench. A conduit connects the inlet sleeve to a water pump. The water pump is started, and clean water is delivered into the inlet sleeve through the conduit. The water in the inlet sleeve flows into a guide pipe through a connecting pipe and is sprayed out through a spray head. The sprayed water falls onto the parts. The controller starts the winding motor and adjusts the angle. The winding motors on both sides of the center of the adjustment frame drive the winding shaft to rotate. Adjusting the direction and speed of the two winding motors causes the rotating winding shafts on both sides to release or retract the traction rope. The released or retracted traction rope drives the guide tube to rotate around the connecting rod, changing the spray angle of the spray head in the horizontal direction. At the same time, the adjusting motor drives the worm wheel to rotate through the worm gear. The rotating worm wheel drives the adjusting frame and the guide tube to rotate, changing the spray angle of the spray head at the bottom of the guide tube in the front-to-back direction. This allows the spray head to spray the accessories from multiple angles, solving the problem that existing simulated rain test equipment cannot change the angle of rain on the accessories, resulting in poor test results.

[0025] The test bench 1 is made of aluminum alloy, and the connection between the adjusting motor 3, the terminal block 6 and the controller 4 is all electrical connection;

[0026] In this embodiment, reference Figure 2 and Figure 3 The spraying mechanism 2 includes an adjusting frame 201 rotatably connected to the top of the test bench 1. A connecting rod 202 is fixedly connected to the bottom center of the adjusting frame 201. A rotating plate 203 is rotatably connected to the bottom of the connecting rod 202. A guide pipe 204 is fixedly connected to the bottom of the rotating plate 203 and below the connecting rod 202. A traction rope 205 is fixedly connected to the top of the guide pipe 204 and on both sides of the connecting rod 202. A winding device is fixedly connected to the outer wall of the traction rope 205 and inside the adjusting frame 201. A winding motor 207 is fixedly connected to the outer wall of the winding shaft 206. A spray head 208 is fixedly connected to the bottom of the guide pipe 204. A connecting pipe 209 is fixedly connected to the top of the guide pipe 204 near the traction rope 205. A water inlet sleeve 210 is fixedly connected to the inside of the adjusting frame 201 and directly above the connecting pipe 209. A worm gear 211 is fixedly connected to the outer wall of the adjusting frame 201 and inside the test bench 1. A worm 212 is meshed with the bottom of the worm gear 211.

[0027] The adjusting frame 201, connecting rod 202, and water inlet sleeve 210 are all made of aluminum alloy. The adjusting frame 201 has an arched structure design. The winding shaft 206 is rotatably connected to the adjusting frame 201, and the worm gear 212 is rotatably connected to the test bench 1. The traction rope 205 is made of nylon rope. There are two sets of the traction rope 205, winding shaft 206, worm gear 212, worm wheel 211, and winding motor 207. The traction rope 205 is slidably connected to the adjusting frame 201. There are multiple sets of spray heads 208.

[0028] The working process of this utility model is as follows: When using the simulated rain test equipment for endurance testing of automotive parts designed in this scheme, the parts are fixedly placed on the test bench 1. A conduit connects the water inlet sleeve 210 to the water pump. The water pump is started, and clean water is sent into the water inlet sleeve 210 through the conduit. The clean water in the water inlet sleeve 210 flows into the guide pipe 204 through the connecting pipe 209 and is sprayed out through the spray head 208. The sprayed clean water falls onto the parts. The controller 4 starts the winding motor 207 and the adjusting motor 3. The winding motors 207 on the left and right sides of the center of the adjusting frame 201 respectively drive two sets of winding motors. The rotating reel 206 adjusts the direction and speed of the two winding motors 207, causing the rotating reel 206 to release or retract the traction rope 205. The released or retracted traction rope 205 drives the guide tube 204 to rotate around the connecting rod 202, thereby changing the spray angle of the spray head 208 in the horizontal direction. At the same time, the adjusting motor 3 drives the worm wheel 211 to rotate through the worm 212. The rotating worm wheel 211 drives the adjusting frame 201 and the guide tube 204 to rotate, changing the spray angle of the spray head 208 at the bottom of the guide tube 204 in the front-to-back direction, so that the spray head 208 can spray the accessories at multiple angles.
