Description

An automobile windshield beam and front wall connecting structure

technical field

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

Background technique

Chinese patent document CN208827950U disclosed on May 7, 2019 "Front windshield frame assembly structure, body frame and automobile", the front windshield frame assembly structure includes: a support tower; a first support plate, a first support plate One end is connected with the support tower; the second support plate, one end of the second support plate is connected with the support tower, and is arranged at intervals with the first support plate; The side is connected with the other end of the first support plate, and the second side of the front windshield beam along its length direction is connected with the other end of the second support plate; the front wall is connected to the support tower and the front windshield beam and a water flow groove, which is connected to the cross beam of the front windshield and is located between the first support plate and the second support plate. In this way, the overall structural strength can be greatly improved, and it can be applied to some severe front windshield installation occasions. And it will not take up too much space in the cabin, which can further optimize the structural arrangement of the cabin. This is a typical prior art, in which the windshield beam is fixed on the front side above the dash panel, and the water trough is fixed on the lower side of the windshield beam on the front side above the dash panel. The water trough is used to receive the rainwater flowing from the windshield of the car and export it to the outside of the car. It protrudes above the front panel and has a considerable width on the front side. One problem with this type of prior art is that the space below the flow tank is difficult to use. Especially below the left and right ends of the water trough, the front side is blocked by the front wheel cover, the outer side is blocked by the inner plate of the A-pillar, and the top is blocked by the water trough, forming a dead corner with only an opening to the middle, whether it is a fixed structure or a The activity structure is extremely inconvenient, and thus basically loses the value of space use. On the other hand, for electric family cars (hereinafter referred to as electric vehicles), there are often many electrical-related parts arranged in the front cabin, so there are higher requirements for the space layout, assembly and maintenance convenience and rigidity of the front cabin; The car also has requirements on the body size and light weight; how to solve the above problems in the limited space structure has become a difficulty in the design of the front cabin structure.

SUMMARY OF THE INVENTION

The layout of the space in the front cabin of the existing electric vehicle is unreasonable, and the connection structure of the windshield beam and the front wall causes part of the space to be idle and cannot be effectively used. The invention provides a connection structure of the windshield beam and the front wall of the vehicle, which can significantly reduce the waste of space under the windshield beam, optimize the space layout structure in the front cabin of the electric vehicle, and facilitate manufacturing and assembly operations.

The connecting structure of the windshield beam and the front panel of this scheme mainly includes four parts: the left and right A-pillar inner panels, the front panel, the front wheel cover and the windshield beam, and does not include the inherent flow groove in the traditional solution. . In this solution without the flow trough, the space below the windshield beam is no longer blocked, so the space is effectively released, and the layout in the front cabin can be further optimized. In particular, the space at both ends of the windshield beam close to the front wheel housing is effectively exposed after the removal of the water trough, so it is no longer an unusable dead corner, and the space in this area can be fully utilized for reasonable planning and layout. It is more conducive to the use of space in the front cabin. As for the flow trough, it can be designed as a movable part that can be disassembled and assembled independently, or can be combined with other similar parts to form a removable waterproof and dustproof assembly, which can continue to function without affecting the space layout of the front cabin. This solution overcomes the inherent technical prejudice and separates the water trough from the dash panel, thus successfully freeing the space under the windshield beam for use. As for the design scheme of the flow tank, those skilled in the art can make full use of the existing technology and choose and determine it according to actual needs.
