AI Technical Summary

Technical Problem

In low-temperature environments, when the vehicle's air conditioning is in recirculation mode, water droplets condense on the roof and drip into the vehicle.

Method used

Design a roof with a sealing structure to seal the gap between the windshield glass and the roof assembly. Use elastic elements to increase the amount of change in the sealing structure to seal installation gaps of various sizes. At the same time, set up L-shaped tubes and sealing blocks to seal the gap between the wiring harness through-hole and the wiring harness.

Benefits of technology

This effectively prevents water droplets from condensing on the roof and dripping into the vehicle when the air conditioning is recirculated in low temperatures, thus improving the sealing effect and preventing air from entering through gaps.

Abstract

This utility model relates to the technical field of automotive parts, and more specifically, to a roof with a sealing structure, including a top sheet metal, a roof assembly, and a windshield. The roof assembly and the windshield are respectively mounted and connected to both sides of the top sheet metal. It also includes a mounting plate, a sealing structure, and an elastic element. The mounting plate is disposed on the roof assembly, and the sealing structure is slidably connected to the mounting plate. The sealing structure slides from the windshield toward the roof assembly, with adjacent sides of the sealing structure sealingly abutting against the roof assembly and the windshield. Both ends of the elastic element are connected to the mounting plate and the sealing structure, respectively. This utility model, by setting a sealing structure to block the gap between the windshield and the roof assembly, and using an elastic element to increase the range of motion of the sealing structure, can block installation gaps of various sizes, preventing water droplets from condensing on the roof and dripping into the vehicle interior when the vehicle is in a low-temperature environment or using air conditioning recirculation mode.
