Description

Automobile air window cross beam and front coaming connecting structure

Technical Field

The invention relates to the field of automobile manufacturing, in particular to a connecting structure of a windshield cross beam and a front wall plate of an electric household car.

Background

Chinese patent document CN208827950U discloses "front windshield frame assembly structure, vehicle body frame, and automobile" in 2019, 5, month and 7, where the front windshield frame assembly structure includes: supporting the tower base; one end of the first supporting plate is connected with the supporting tower seat; one end of the second supporting plate is connected with the supporting tower seat and is arranged at intervals with the first supporting plate; the first side of the front windshield cross beam along the length direction of the front windshield cross beam is connected with the other end of the first supporting plate, and the second side of the front windshield cross beam along the length direction of the front windshield cross beam is connected with the other end of the second supporting plate; the front wall plate is connected to the same side of the support tower seat and the front windshield beam; and the water flowing groove is connected with the front air window cross beam and is positioned between the first supporting plate and the second supporting plate. Therefore, the strength of the whole structure can be greatly improved, and the mounting method can be suitable for certain severe mounting occasions of the front windshield. And the structure layout of the cabin can be further optimized without occupying too much space of the cabin. This is typical of the prior art, in which a louver beam is fixed to the upper front side of the front panel, and a gutter channel is fixed to the lower side of the louver beam to the upper front side of the front panel. The water flowing groove is used for receiving rainwater flowing down from an automobile windshield and guiding the rainwater out of the automobile, the rainwater protrudes out of the front side above the front coaming, the rainwater has a certain width, and two ends of the rainwater are in lap joint with the front wheel cover structure. One problem with this type of prior art is that the space below the launder is difficult to utilize. Especially, the front side of the lower part of the left end part and the right end part of the launder is shielded by a front wheel cover, the outer side of the launder is shielded by an A-pillar inner plate, and the upper part of the launder is blocked by the launder, so that a dead angle which is only provided with an opening towards the middle is formed, and the mounting and fixing structure and the movable structure are inconvenient, thereby basically losing the space use value. On the other hand, for an electric household car (hereinafter referred to as an electric vehicle for short), the number of related parts of electric appliances arranged in the front cabin is often large, so that high requirements are provided for the space arrangement, the general assembly and maintenance convenience and the rigidity of the front cabin; meanwhile, the electric vehicle has requirements on the size and the light weight of the vehicle body; how to solve the above problems on a limited space structure becomes a difficult point of the design of the front cabin structure.

Disclosure of Invention

The spatial layout is unreasonable in current electric motor car front deck, and wind window crossbeam and preceding bounding wall connection structure lead to partial space idle, can't effectively utilize. The invention provides a connecting structure of an automobile air window cross beam and a front wall plate, which can obviously reduce the space waste below the air window cross beam, optimize the space layout structure in the front cabin of an electric vehicle and facilitate the manufacturing and assembling operation.
