Description

Technical Field

[0001] The present invention relates to the technical field of new energy vehicles, and in particular to waterproof testing equipment for new energy vehicles. Background Art

[0002] Waterproofing testing is a type of automotive inspection used to verify the sealing of automotive parts and components, providing a basis for product reliability. As new energy vehicles are primarily powered by electricity, their sealing is higher than that of conventional fuel vehicles. Therefore, every electric vehicle must undergo rigorous waterproofing testing before leaving the factory. Existing waterproofing tests generally involve driving the vehicle into a scaffold-like spraying device, which statically sprays the vehicle to test its sealing. However, static spraying cannot effectively simulate the conditions experienced during daily driving, resulting in significant discrepancies between the test data and those obtained during daily use.

[0003] Moreover, when the vehicle is stationary, the underside of its frame is rarely affected by water flow. However, during actual driving, the bottom of the vehicle will be splashed with a large amount of rainwater during driving. Therefore, the waterproofness test of the bottom of the vehicle also needs to be paid attention to, and a device is needed to improve the authenticity of the waterproof test.

[0010] Preferably, the output end of the fan faces downward, and the upper surface area of ​​the baffle is larger than the upper surface area of ​​the fan.

[0028] The support mechanism 8 also includes a limiting wheel 807, one end of which is fixedly connected to one end of the rotating shaft 805, and the lower side of the outer wall of the limiting wheel 807 is engaged with the limiting frame 808. The lower surface of the limiting frame 808 is fixedly connected to a fixed frame 809, and the fixed frame 809 is a square frame structure. The lower surface of the middle part of the fixed frame 809 is fixedly connected to a hydraulic rod 810, and the lower end of the hydraulic rod 810 is fixedly connected to the upper surface of the base plate 801. The support mechanism 8 also includes a counterweight block 811, and the outer wall of the counterweight block 811 is fixedly connected to the outer wall of the rotating shaft 805. The counterweight block 811 is a metal block with an arc-shaped structure.

[0029] The exhaust mechanism 9 includes a waterproof shell 901, the outer wall of the waterproof shell 901 is fixedly connected to the outer wall of the fixed plate 1, the inner wall of the waterproof shell 901 is fixedly connected to a motor 902, the output end of the motor 902 is fixedly connected to a rotating rod 903, one end of the rotating rod 903 passes through the fixed plate 1 and extends to the inside of the mounting groove, the end of the rotating rod 903 away from the motor 902 is rotatably connected to the inner wall of the mounting groove through a bearing, the outer wall of the rotating rod 903 is fixedly connected to a baffle 904, the lower surface of the baffle 904 is fixedly connected to a mounting frame 905, the lower surface of the mounting frame 905 is fixedly connected to a fan 906, the output end of the fan 906 faces downward, and the upper surface area of ​​the baffle 904 is larger than the upper surface area of ​​the fan 906.

[0030] When in use, the support legs 2 and the lower side of the bottom plate 801 are fixed to the ground, and ramps are built on the front and rear sides of the fixing plate 1 to allow vehicles to go up and down the slope. The lower side of the fixing plate 1 is suspended in the air to facilitate water discharge. The vehicle is driven onto the fixing plate 1, and then water is input into the water inlet pipe 4 through the external water supply device. The water is conducted through the main pipe 3, the exhaust pipe 6, and the nozzle 7, and is quickly sprayed onto the vehicle from the nozzle 7, so that the vehicle is sprayed in a surrounding manner, which can simulate heavy rain weather and further test the vehicle's sealing and achieve the purpose of testing the vehicle's waterproof performance.

[0031] When the vehicle drives onto the fixed plate 1, the wheels of the vehicle can be stopped between two adjacent anti-skid rollers 806 respectively, and then the hydraulic rod 810 is started to contract and pull the fixed frame 809 downward, so that the fixed frame 809 drives the limiting frame 808 to move downward, so that the limiting frame 808 is separated from the surface of the limiting wheel 807. At this time, the limiting wheel 807 can rotate freely, and the vehicle is started to accelerate, so that the tires of the vehicle rotate, and the wheels maintain a fast rotation state to simulate driving behavior. The wheels will quickly splash the water sprayed on the tires backwards, so that the water flow strongly hits the bottom plate and the vehicle gap near the wheel hub where it is difficult to handle, thereby increasing the test simulation and the reliability of the waterproof test;

[0032] While the vehicle is running, the starter motor 902 drives the rotating rod 903 to rotate, thereby deflecting the baffle 904, the mounting frame 905, and the fan 906 so that the output end of the fan 906 is directed toward the bottom of the vehicle. Then, the fan 906 is started to spray a large amount of airflow toward the lower part of the vehicle, so that the water sprayed by the nozzle 7 is quickly atomized by the airflow and blown toward the vehicle body and the bottom of the vehicle. When the bottom of the vehicle is splashed with water by the wheels, it is also blown by a strong airflow, simulating the airflow movement and the diffusion of water mist at the bottom of the vehicle when the vehicle is running, simulating water seepage through tiny gaps, thereby increasing the authenticity of the waterproof test of new energy vehicles;

[0033] When the anti-skid roller 806 is driven by the wheel to rotate rapidly, the anti-skid roller 806 drives the rotating shaft 805 to rotate, and the rotating shaft 805 drives the counterweight 811 to rotate rapidly, which causes the counterweight 811 to continuously change its center of gravity during rotation. The rapid rotation state drives the rotating shaft 805, the anti-skid roller 806, the vehicle, and the bracket 803 to vibrate rapidly under the support of the spring 804, so that the vehicle simulates the vibration of the vehicle body during driving, prevents the gap of the vehicle body from being difficult to reveal in the static state, and makes the vehicle be washed by water flow, water mist, and air flow during the vibration, thereby increasing the realism of the test;

[0034] After the vehicle waterproof test is completed, the water supply to the water inlet pipe 4 is stopped. After the vehicle is stable, the hydraulic rod 810 is started to push up the fixed frame 809, so that the fixed frame 809 pushes up the limiting frame 808, so that the limiting frame 808 clamps the limiting wheel 807, and the vehicle drives down the fixed plate 1.

[0035] The above are only preferred specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
