Description

Door sealing strip and vehicle Technical Field The utility model relates to the field of vehicle parts, in particular to a vehicle door sealing strip and a vehicle. Background In the assembly of a door of a motor vehicle, it is generally necessary to provide a door seal at the edge of the door opening in the door frame, the door being closed by pressing the seal to achieve a sealing engagement with the door frame. In order to avoid uncomfortable riding experience of drivers and passengers in the vehicle caused by vibration of a vehicle door, particularly a back door, when the vehicle runs on a bumpy road section, sponge rubber with high foaming rate is generally selected to manufacture sealing strips so as to improve sealing counter force, but the effect is not ideal enough, and the vibration of the vehicle door cannot be limited effectively. Disclosure of utility model The utility model aims to solve the technical problem that the sealing counterforce of the door sealing strip in the related art is smaller and cannot meet the running requirements of vehicles under different road conditions. In one aspect, the utility model provides a vehicle door sealing strip, which comprises a sealing strip body and a reinforcing structure, wherein the sealing strip body is used for being installed on a vehicle door frame, a sealing bubble which extends along the length direction of the sealing strip body and is used for being in contact with a vehicle door is arranged on the sealing strip body, a cavity is formed in the sealing bubble, the reinforcing structure is located in the cavity, and the reinforcing structure and the sealing strip body are of an integrated structure.
