Vehicle body top cover of new energy passenger car

Abstract

The invention relates to a vehicle body top cover of a new energy passenger car; the top cover comprises a top cover main body, the top cover main body is integrally formed by adopting a composite material, an overhead air conditioner base, an overhead power battery box body fixing tray and a skylight mounting spigot are integrated on the top cover main body, and the composite material is of a three-layer sandwich structure and comprises an outer surface layer, a sandwich layer and a bottom layer. The outer surface layer and the bottom layer are both of a carbon fiber material, a glass fiber material or a fiber structure formed by alternately laying the carbon fiber material and the glass fiber material, and the sandwich layer is one of rigid foam, PET (Polyethylene Terephthalate) or a honeycomb material. According to the invention, the integrated design and molding of each component mounting structure and the top cover structure can be realized, so that the bearing capacity of the composite top cover structure can be fully exerted, the lightweight and intensive design of the top cover can be effectively realized, the modular mounting and manufacturing of the top cover can be realized, and compared with the traditional top cover, the number of parts is greatly reduced, and the mass is reduced by more than 30%.

Description

technical field [0001] The invention relates to the technical field of new energy passenger cars, and more specifically refers to a vehicle body roof of a new energy passenger car. Background technique [0002] In recent years, more and more new energy buses have adopted the arrangement of batteries on top. For example, the Chinese utility model whose authorized notification number is CN207388834U discloses a battery bracket for the top of the battery, including a rectangular frame structure composed of square pipes welded, and the power battery is fixed to the square pipe inside the rectangular frame structure by bolts Above, the entire rectangular frame structure is fixed at a fixed position on the roof of the vehicle body through connectors. This kind of top-mounted battery bracket does not occupy the space in the car and is of sufficient height, which can save the whole vehicle wading test and reduce the cost of the whole vehicle test. [0003] However, there are still...
