[0002] A vehicle rain test evaluates the impact of rain on a vehicle's water management performance, simulating a vehicle parked in the rain or undergoing a car wash. A key indicator of vehicle water management performance, the rain test not only reflects a vehicle's adaptability to high humidity but also assesses whether it faces leakage risks. Vehicle water management performance is crucial for ensuring a vehicle's ability to adapt to the complex and ever-changing natural environment. The rain test focuses not only on leak risk but also on the vehicle's water management performance in various rain positions, including horizontal, forward, backward, left, and right, to simulate a vehicle parked on a slope or curb.

[0003] Currently, when conducting whole-vehicle rain tests, they are generally only conducted in a horizontal position in a rain room, or the vehicle is tested off the production line. These are simple rain tests with a single test condition. It is difficult to ensure that the vehicle is always in a horizontal position when the user actually uses the vehicle. Therefore, conducting a horizontal position rain test in a rain room or conducting a vehicle off the production line rain test cannot cover the common working conditions of the vehicle during use. Based on this, in order to realize the whole-vehicle rain test in different vehicle body postures, a device with adjustable vehicle body posture is needed to ensure the diversity of working conditions of the whole-vehicle rain test.
