[0026] like Figure 4 As shown, the vehicle wiper durability test bench includes vehicle bridge components 3 that cooperate with the wheels on both sides of the vehicle. There are two corresponding sets of vehicle bridge components 3, which are the core support structure of the test bench and are used to support the vehicle. It consists of multiple bridge frames 302, which are tightly connected from front to back to form a passageway for the vehicle. Each bridge frame 302 is fixed with an anti-slip patterned cover plate 301 to increase the friction when the vehicle travels on the vehicle bridge component 3, preventing slippage and ensuring the stability and safety of the vehicle during the test. Each bridge frame 302 has an anti-slip rubber pad fixed to its bottom to increase the friction between the bridge frame 302 and the ground, preventing displacement of the bridge frame 302 during operation. The vehicle bridge components 3 cooperate with the wheels on both sides of the vehicle, providing a platform for the vehicle to be placed and driven.

[0027] One end of the vehicle bridge assembly 3 is equipped with a ramp bridge assembly 4, the main function of which is to guide the vehicle uphill. The ramp design allows the vehicle to smoothly drive onto the vehicle bridge assembly 3, facilitating the vehicle's positioning at the start of the test. The angle and length of the ramp can be adaptively adjusted according to specific circumstances to accommodate the climbing ability of different types of vehicles, ensuring that the vehicle can safely and smoothly enter the test position.

[0028] When making, the main body of the bridge 302 and the ramp bridge assembly 4 is preferably welded by a 40x40x2.5mm square steel, the upper surface of the main body is welded with a 5mm-thick anti-skid cover plate 301, the anti-skid cover plate 301 is made of a steel plate, and the lower surface of the main body is fixedly installed with an anti-skid rubber pad, so that the support strength of the bridge 302 and the ramp bridge assembly 4 is ensured, and the anti-skid performance of the bridge 302 and the ramp bridge assembly 4 is improved.

[0029] The vehicle bridge assembly 3 is provided with a support frame 5 on one side or both sides, in the embodiment, the vehicle bridge assembly 3 is provided with the support frame 5 on both sides, and the two support frames 5 cooperatively act to better support and fix the cross beam 501. The two ends of the cross beam 501 are fixedly connected with the two support frames 5 respectively, and the cross beam 501 is arranged above the top of the whole vehicle, the support frame 5 is installed with a spray head 8 on the cross beam 501, and the height and position of the cross beam 501 can be adaptively adjusted according to specific conditions to ensure that the spray head 8 installed thereon can accurately spray water to the top of the whole vehicle and the front and rear windshield glasses to simulate a rainfall environment.

[0030] When making, the support frame 5 is preferably made of a 40 profile, the support frame 5 of this structure has high flexibility, is detachable, and has light weight.

[0031] The spray head 8 is communicated with the water storage tank 1 through the water pipe 7, the spray head 8 is used to simulate rainfall, the water pump 2 is installed on the water pipe 7, and the water pump 2 can pump water in the water storage tank 1 out and smoothly deliver the water to the spray head 8 through the water pipe 7. The water inlet end of the water pump 2 is provided with a filter screen one (not shown in the figure), the filter screen one can filter impurities in the water to prevent the impurities from entering the water pump 2 and the spray head 8 to avoid blocking and damaging the pipeline and equipment.

[0032] The support frame 5 is provided with a water baffle 6, that is, the water baffle 6 is arranged on both sides of the whole vehicle, and the water baffle 6 is made of transparent PVC material. The PVC material has good oil and water resistance effect, low cost, aging resistance, and good reliability; the transparent material enables the test personnel to clearly observe the situation of the whole vehicle in the test process, and the water baffle 6 can effectively block the water sprayed by the spray head 8 from splashing everywhere, limit the water in a certain area, and improve the accuracy and controllability of the test.

[0033] A water tank 9 is arranged below the spray head 8, the water tank 9 can recycle the water sprayed by the spray head, and the water tank 9 is provided with an anti-rust coating, so that rusting of the water tank 9 caused by long-time contact with water is prevented, and the service life of the water tank 9 is prolonged. The water tank 9 is provided with an anti-skid rubber layer at the bottom, the anti-skid rubber layer increases the friction force of the bottom of the water tank 9 to prevent the water tank 9 from sliding when being placed or moved.

[0034] In this embodiment, the water tank 9 is preferably arranged at the bottom of the vehicle bridge assembly 3, and a plurality of handles 901 are fixedly connected to the two sides of the water tank 9, facilitating the test personnel to carry and move the water tank 9. The water tank 9 is provided with a water outlet at the bottom, which is used to discharge the collected water for reuse.

[0035] A detachable filter screen No. 2 is arranged at the water outlet in the water tank 9, and a drain pipe 10 is connected to the outside of the water outlet, and a drain valve is arranged on the drain pipe 10. The filter screen No. 2 is connected to the water outlet by existing buckling or screwing, and is used to filter impurities in the water tank 9 to prevent the impurities from entering the drain pipe 10 and blocking the pipeline. By controlling the opening and closing of the drain valve, the discharge of water in the water tank 9 can be controlled, facilitating the treatment and management of the collected water.

[0036] In the manufacturing process, the water tank 9 and the handles 901 are preferably made of stainless steel, and the outer dimensions of the water tank 9 are 2500x2200x250mm, and the wall thickness is 4mm.

[0037] Working principle:

[0038] As shown in Figs. Figure 5 and ​ , before the test, a certain amount of water is stored in the water storage tank 1. Start the car model 11, and make the car model 11 run on the vehicle bridge assembly 3 to simulate the actual driving condition of the vehicle on the road, and park the vehicle on the vehicle bridge assembly 3 to ensure that the spray head 8 is aimed at the upper part of the windshield glass; the direction of the vehicle head can also be adjusted to conduct a rain-scraper durability test on the rear windshield glass.

[0039] When the test starts, the water pump 2 is started to pump the water in the water storage tank 1 out and deliver it to the spray head 8 through the water pipe 7, and the spray head 8 sprays the water evenly to simulate rainfall. The wiper system of the vehicle works under the condition of rainfall to wipe off the water on the windshield glass, and the test personnel observes the working condition of the wiper to evaluate its water wiping effect, durability and reliability. By adjusting the water spraying intensity of the spray head 8 and the driving speed of the vehicle through the water pump 2, different rainfall conditions and driving conditions can be simulated to comprehensively test the wiper system of the whole vehicle.

[0040] During the test, the sprayed water will eventually drip into the water tank 9, and the water collected by the water tank 9 is discharged to a designated position through the water outlet and the drain pipe 10, or is returned to the water storage tank 1 through the pipeline to realize the recycling of water.

[0041] Finally, although the present specification is described in terms of embodiments, each embodiment does not necessarily contain only one independent technical solution, and the description manner of the specification is only for the sake of clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be appropriately combined to form other embodiments that can be understood by those skilled in the art.
