Description

Detection method, device and equipment for state of drain pipe facing vehicle skylight Technical Field The application relates to the technical field of vehicles, in particular to a method, a device and equipment for detecting the state of a water drain pipe facing a vehicle skylight. Background In modern automotive designs, vehicles are often designed with multiple drain pipes on the sunroof frame to direct the water out of the vehicle in order to prevent the water from entering the vehicle. However, after the skylight drain pipe is used for a long time, the skylight drain pipe is easy to block an outlet due to sundries such as mud, leaves, insects and the like, so that accumulated water cannot be discharged in time. Since the drain outlet is typically located in a vehicle chassis or hidden location, the user cannot directly observe its condition by eye or normal operation. When the blockage problem is accumulated to a certain extent, accumulated water can reversely permeate into the vehicle, so that parts such as carpets, seats and the like are soaked, and potential safety hazards such as circuit short circuit and the like are even caused. The existing vehicles lack an active detection means for the blocking state of the drain pipe, users often find the blocking state passively after problems occur, so that the maintenance cost is high and the user experience is damaged.
