Two-way sealing device for vehicle skylight

Abstract

The invention discloses a two-way sealing device for a vehicle skylight, and relates to the technical field of sealing devices. The two-way sealing device for the vehicle skylight comprises a sealingstrip, wherein the sealing strip is arranged on a guide rail of the vehicle skylight in a clamping mode, and the sealing strip is located between skylight glass of the vehicle skylight and a skylightopening part of the vehicle skylight. The sealing strip comprises a dense part, a first elastic sealing part connected with one side of the dense part and a second elastic sealing part connected withthe other side of the dense part. Cavities are separately formed between the first elastic sealing part and the dense part as well as between the second elastic sealing part and the dense part, an airhole is formed in the dense part, and the air hole separately communicates with the two cavities. A clamping groove body is arranged in the dense part, an opening is formed in the lower end of the dense part, the opening communicates with the clamping groove body, and the sealing strip is arranged on the guide rail through the clamping groove body in a clamping mode. The two-way sealing device for the vehicle skylight has the characteristics of simple structure, low cost, good and reliable sealing performance.

Description

technical field [0001] The invention relates to the technical field of sealing devices, in particular to a two-way sealing device for a vehicle sunroof. Background technique [0002] The car sunroof is installed on the roof, which can effectively circulate the air in the car and increase the entry of fresh air. In rainy days, the car sunroof can prevent rainwater from penetrating into the car from the top of the car. Therefore, when the car sunroof is closed, it must be closed. Has good sealing. [0003] The sealing strip is an important part of the car sunroof. The sealing and waterproof functions of the sunroof are realized through the sealing strip. The sunroof sealing strip in the prior art generally adopts pasting sealing strips, and the tape uses 3M tape. If the body sheet metal has no card When the skylight is affected by high temperature and low temperature, the bonding strength of the tape will also be affected, which will weaken the sealing effect of the pasted se...
