Description

Technical Field

[0001] This utility model relates to the field of automotive testing technology, specifically a brake testing platform for automotive testing. Background Technology

[0002] Vehicle inspection is a comprehensive check and evaluation of a vehicle's braking system to ensure its safety and effectiveness. This inspection typically includes checking components such as brake pads, brake discs, brake fluid, and brake wiring. It can detect potential faults or wear, ensuring timely and reliable braking during driving. Regular brake inspections can significantly reduce the risk of accidents and ensure driving safety.

[0003] In existing technology, the simplest way to clean the rollers of an automotive brake testing bench is to use a high-pressure water gun to spray the roller surface. Simply spray water onto the roller surface to remove attached dirt and dust, and then wipe it dry with a cloth.

[0004] High-pressure water flow may damage the surface coating of the roller or other components, and the wastewater generated during cleaning may cause environmental pollution and must be properly treated. It may not be able to completely remove stubborn dirt or grease from the roller, and the water after cleaning cannot be reused. To address the above problems, a brake testing bench for automobile testing is proposed. Utility Model Content

[0007] By adopting the above technical solution, the output end of the first water pump is a flexible hose. The first water pump transmits the filtered water to the spray pipe, and sprays the surface of the test platform or the car through the spray pipe to realize the test of the car's brakes in rainy conditions.

[0008] As a further description of the above technical solution: the limiting component includes two first servo motors, the first servo motors are fixedly connected to the front end of the fixed block, the output end of the first servo motors is fixedly connected to a first bidirectional threaded rod, the outer ring of the first bidirectional threaded rod is threaded with a first nut pair, and the top of the first nut pair is fixedly connected to a limiting plate.

[0015] By adopting the above technical solution, the damping spring and buffer pad can effectively buffer the impact on the car.

[0016] As a further description of the above technical solution: a drainage groove is provided in the middle of the top of the platform.

[0017] By adopting the above technical solution, the drainage trough can drain water from the surface of the platform.

[0018] As a further description of the above technical solution: both sides of the sealing block are fixedly connected with tenon blocks, and the tenon blocks are connected to the front end of the platform body through and slidingly.

[0019] By adopting the above technical solution and using the tenon and mortise mechanism, the sealing block can only be pulled out by human intervention.

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.

[0032] To further understand the contents of this utility model, a detailed description of this utility model will be provided with reference to the accompanying drawings.

[0033] Reference Figure 1 and Figure 4 This utility model discloses a brake testing platform for automobile testing, including a support plate 1, a drainage groove 29 in the middle of the top of the platform 2, a partition above the drainage groove 29 to facilitate the movement of the automobile on the platform 2, tenon blocks 17 fixedly connected to both sides of the sealing block 16, and the tenon blocks 17 penetrate and slide to the front end of the platform 2. The design of the tenon blocks 17 can prevent the sealing block 16 from falling off naturally. Baffles 12 are fixedly connected to both ends of the top of the brush plate 11 to prevent water from sliding out from both ends of the brush plate 11.

[0034] Reference Figures 1-3A platform 2 is fixedly connected to the bottom center of a support plate. Pipes 14 are fixedly connected to both sides of the inner wall of the platform 2, allowing the cleaned liquid to be transferred to a water tank 3. A sealing block 16 is slidably connected to the front end of the pipe 14, ensuring a tight seal. A filter plate 15 is fixedly connected to the rear end of the sealing block 16, filtering the cleaned liquid. A brush plate 11 is fixedly connected to the top of the pipe 14, wiping the outer ring of the roller. Evenly distributed nozzles 13 are fixedly connected to the top of the brush plate 11, spraying water onto the surface of the roller. A second water pump 9 is fixedly connected to the middle of the inner wall of the platform 2, with hoses 10 fixedly connected to the output ends of the second water pump 9. The hoses 10 are connected to the brush plate. The bottom of the support plate 11 is connected through and fixedly. The top of the brush plate 11 is equipped with evenly distributed nylon brushes. The bottom of the platform 2 is fixedly connected to the water tank 3. The bottom of the inner wall of the water tank 3 is fixedly connected to the first water pump 4. The output end of the first water pump 4 is fixedly connected to the spray pipe 5. The spray pipe 5 can spray the platform 2 or the car to simulate braking test in the rain. The top two ends of the support plate 1 are fixedly connected to the frame 6. The top of the frame 6 is fixedly connected to the lead screw motor 7. The output end of the lead screw motor 7 is fixedly connected to the threaded plate 8. The rotation of the lead screw motor 7 causes the threaded plate 8 to move up and down. One end of the threaded plate 8 is connected through and fixedly connected to the spray pipe 5. The movement of the threaded plate 8 drives the spray pipe 5 to move, which facilitates the adjustment of the spray height. The bottom two sides of the support plate 1 are fixedly connected to the fixing block 22. The front end of the fixing block 22 is equipped with a limit component.

[0035] Reference Figure 1 and Figure 4 The limiting component includes two first servo motors 18, which are fixedly connected to the front end of the fixed block 22. A first bidirectional threaded rod 19 is fixedly connected to the output end of each first servo motor 18. The first servo motors 18 drive the first bidirectional threaded rod 19 to rotate. A first nut pair 20 is threadedly connected to the outer ring of each first bidirectional threaded rod 19. Movement of the first bidirectional threaded rod 19 causes the first nut pair 20 to move simultaneously inward or outward. A limiting plate 21 is fixedly connected to the top of the first nut pair 20. The limiting plate 21 is composed of multiple honeycomb blocks. The front middle of the platform 2 is fixed... A second servo motor 23 is connected, and a second bidirectional threaded rod 24 is fixedly connected to the output end of the second servo motor 23. The second servo motor 23 drives the second bidirectional threaded rod 24 to rotate. The outer ring of the second bidirectional threaded rod 24 is threaded with a second nut pair 25. A fixing plate 26 is fixedly connected to the top of the second nut pair 25. A damping spring 27 is fixedly connected to one end of the fixing plate 26. The damping spring 27 can provide secondary buffering for the vibration of the buffer pad 28. The buffer pad 28 is fixedly connected to one end of the damping spring 27. The buffer pad 28 performs the first buffering and shock absorption after being impacted.

[0036] Working principle: When cleaning the rollers of the platform 2, the second water pump 9 transmits water through the hose 10 to the brush plate 11, and then sprays it onto the rollers through the nozzle 13. During the spraying process, the nylon brushes on the surface of the brush plate 11 wipe the rollers. After spraying, the water enters the pipe 14 through the concave shape of the brush plate 11. The filter plate 15 in the pipe 14 filters the impurities in the water, and then the water enters the water tank 3. When it is necessary to simulate braking in rainy weather, the first water pump 4 transmits the water from the water tank 3 to the spray pipe 5 to achieve the spraying effect. When it is necessary to adjust the height of the spray pipe 5, the screw motor 7 drives the threaded plate 8 to move the spray pipe 5 up and down to adjust the height according to different needs. When it is necessary to disassemble the filter plate 15, the filter plate 15 can be pulled out by pulling out the sealing block 16, thus allowing the filter plate 15 to be cleaned. During brake testing of a vehicle, when both tires enter the rotating rollers, the first servo motor 18 drives the first bidirectional threaded rod 19 to rotate, causing the first nut assembly 20 to move the limiting plate 21 simultaneously. Adjusted according to the distance of the vehicle tires, the limiting plate 21, composed of multiple honeycomb blocks, buffers the vehicle in case of impact due to inertia during testing. The second servo motor 23 drives the second bidirectional threaded rod 24 to rotate, causing the second nut assembly 25 to move the fixing plate 26. The movement of the fixing plate 26 limits the sides of the vehicle with the buffer pad 28. When the vehicle slips and sways left and right during rotation, the buffer pad 28 provides the first buffering, and the damping spring 27 provides the second buffering, thus preventing vehicle slippage and property damage, and protecting the vehicle.
