Vehicle door edge inflation sealing structure

Abstract

The invention provides a vehicle door edge inflation sealing structure belonging to the field of vehicle door sealing. The vehicle door edge inflation sealing structure provided by the invention greatly improves the safety and the driving comfort of the entire vehicle. The sealing structure comprises a sealing strip, a vent pipe, a locking nut, an outer gasket, an inner gasket and a mounting slot, wherein the sealing strip is in a sealed cavity structure made of rubber materials and is embedded inside the mounting slot during inflation. In the invention, a vehicle door is sealed by utilizing the expansion caused by the inflation of the sealing strip, and gas has flowability in a sealed cavity, therefore, all parts with different gap values can be kept to have the same sealing pressing force. The sealing strip of the sealing structure has large sealing compensation dosage and uniform sealing pressing force, is particularly suitable for vehicles with larger vehicle door gaps, reliable in sealing, small in size and light in weight and makes up the defect that the traditional rubber sealing strip cannot seal larger gaps at the vehicle door.

Description

technical field [0001] The invention belongs to the field of sealing of vehicle doors, and in particular relates to an inflatable sealing structure at the edge of a vehicle door. Background technique [0002] At present, most of the door seals used on vehicles in our country are solid or hollow sealing rubbers that are pressed to seal the doors. Use solid or hollow sealing rubber to seal the vehicle door. The initial sealing effect is better, but with the aging of the rubber and the increase of the gap between the door and the body, the sealing effect of this form is greatly reduced, and the safety of the whole vehicle cannot be guaranteed. safety. [0003] In many vehicle fields such as construction machinery, since the body adopts a thicker steel plate (generally 5-6cm) welded structure, in order to ensure the performance requirements of the vehicle, full welding is often used. The lack of sealing caused by welding deformation at the door becomes the key point. Pay atten...
