Description

Sealing structure at top of vehicle door and vehicle Technical Field The invention relates to the technical field of vehicles, in particular to a sealing structure of a top of a vehicle door and a vehicle. Background With the increasing aesthetic demands of the public and the increasing competition of the appearance of the automobile market, more and more frameless doors are produced on the market. The vehicle window of the frameless vehicle door has no frame, and compared with the traditional framed vehicle door, the frameless vehicle door has more moving and younger appearance, and gives people the feeling of high grade, cool and simple. The sealing structure of the frameless car door in the related art comprises a side wall decorative strip arranged on a car body side wall metal plate (namely a car body door frame), a side wall sealing strip connected with the side wall decorative strip and car window glass arranged on the car door. The side wall trim comprises an outer plate part which is flush with the outer wall of the side wall metal plate of the vehicle body and an inner plate part which is connected with one end of the outer plate part far away from the outer glass, wherein the inner plate part is positioned on the inner side of the outer plate part and fixedly connected with the side wall metal plate of the vehicle body. And a decorative strip sealing strip is clamped between the inner plate part and the side wall metal plate of the vehicle body, and is positioned outside the rivet, so that the tightness between the inner plate part and the side wall metal plate of the vehicle body can be further improved. Thus, it can be seen that the sealing structure in the related art is complex, the side wall bright wisp is assembled on the side wall of the vehicle body through the assembly, and forms clearance surface difference fit with the side wall outer plate, so that the side surface appearance effect forms block cutting and cracking, and an independent sealing strip is needed to prevent water from blocking seams. Therefore, how to reduce the complexity of the sealing structure of the frameless door to improve the production efficiency of the sealing structure is one of the technical problems to be solved. Disclosure of Invention In view of the above-mentioned shortcomings of the prior art, an object of the present application is to provide a sealing structure for a door top and a vehicle, which aims to solve the problem of complex sealing structure of a frameless door in the prior art. In a first aspect, the embodiment of the application provides a sealing structure for the top of a vehicle door, which comprises a side wall plate assembly, a window frame sealing strip, a reinforcing plate and a fixing plate, wherein the side wall plate assembly comprises a side wall outer plate and a side wall inner plate, the reinforcing plate is arranged between the side wall outer plate and the side wall inner plate, the fixing plate is fixedly connected with the reinforcing plate, an accommodating groove is formed in the fixing plate, the window frame sealing strip is arranged in the accommodating groove, and the window frame sealing strip is suitable for sealing the vehicle door in a matched mode with window glass. According to the technical means, the sealing structure provided by the embodiment of the application has the advantages that the reinforcing plate is arranged between the side wall outer plate and the side wall inner plate, the fixing plate is fixedly connected with the reinforcing plate, and the accommodating groove for accommodating the window frame sealing strip is formed in the fixing plate, so that the side wall decoration strip and the decoration strip sealing strip in the related technology are omitted, the complexity of the sealing structure can be reduced, the time required for installing the sealing structure is shortened, the production efficiency of the sealing structure is improved, and the material cost can be reduced. In one possible embodiment, a receiving gap is formed between the side outer panel and the side inner panel, the fixing plate is disposed in the receiving gap, and the fixing plate is connected to the side outer panel. According to the technical means, since the fixing plate is arranged in the accommodating gap formed between the side outer plate and the side inner plate, then the window frame sealing strip is also positioned in the accommodating gap, and then the window frame sealing strip can be shielded by the side outer plate, so that the sealing strip is almost invisible on the front side visual field, the effect of hiding the window frame sealing strip is formed, and the overall simplicity of the appearance of the door is ensured. In addition, the embodiment of the application eliminates the side wall decorative strip and the decorative strip sealing strip, thus eliminating the gap surface difference between the side wall decorative strip and the side wall outer plate
