Abstract

The invention relates to the related technical field of the automobile field, in particular to an automobile roof plate with excellent flame retardant and heat insulation effect in the automobile field, comprising a reinforcing beam, a top cover, a ceiling plate and an interior layer, and a plurality of reinforcing beams are arranged at equal intervals, And the two ends of the reinforcement beams are respectively fixed on the side frames on both sides of the car through the fixed structure, the two ends of the roof panel are installed on the two adjacent reinforcement beams, the top cover is arranged on the upper surface of the roof panel, and the interior decoration layer. It is arranged on the lower surface of the roof panel; by arranging the vehicle roof panel composed of the reinforcement beam, the top cover, the roof panel and the interior layer, and by arranging the reinforcement beam to be composed of the main beam plate and the reinforcement rib, and the main The beam plate and reinforcing bar are arranged in an inverted T-shaped structure, thereby effectively improving the overall strength of the car roof, and the meshing installation between the roof plate and the reinforcing beam can improve its overall stability and ensure its connection. of aesthetics.

Description

technical field [0001] The invention relates to the related technical field of the automobile field, in particular to an automobile roof plate with excellent flame retardant and heat insulation effect in the automobile field. Background technique [0002] A car is a non-track-bearing vehicle with 4 or more wheels, mainly used for carrying people or goods; a vehicle for towing people or goods, the roof of the car is the roof part of the car, and the roof of the car is the interior of the car. An important part, it not only has the function of decoration, but also has the function of sound insulation and heat insulation. Many cars feel very hot on the top of the head in the summer sun, and the roof crackles when it rains, which means that the sound insulation and heat insulation of the roof are not good , thereby affecting the riding comfort of the occupants. Therefore, the present invention proposes an automobile roof plate with excellent flame retardant and heat insulation e...

Problems solved by technology

[0002] A car is a non-track-bearing vehicle with 4 or more wheels, mainly used to carry people or goods; for vehicles that tow people or goods, the roof of the car is the roof part of the car, and the roof of the car is the interior of the car. An important component, it not only has the function of decoration, but also has the function of sound insulation and heat insulation. Many cars feel very hot under the sun in summer, and the roof crackles when it rains, because the sound insulation and heat insulation of the roof are not good. , thereby affecting the ride comfort of the occupants, for this reason, the present invention proposes a car roof with excellent flame-retardant and heat-insulating effects in the automotive field to solve the above-mentioned problems
