A curved automobile front beam assembly

Abstract

The invention discloses a cambered automobile front beam assembly. The cambered automobile front beam assembly includes an automobile top cover and a front beam main body; and the front beam main body is horizontally fixed on the front top of the automobile top cover, supporting bases are arranged around the bottom of the automobile top cover, the supporting bases on the same side are connected with two ends of connection rods, the connection rods on the both sides are connected through two reinforced rods which are embedded in the inner part of the bottom side of the automobile top cover, installation bases are arranged around the top of the automobile top cover, one ends of a first support top frame and a second support top frame are provided with sockets, and the first support top frame and the second support top frame are fixed on the installation bases through the sockets. According to the cambered automobile front beam assembly, the structure of the front beam main body is optimized, the rigidity and high intensity of the front beam main body are guaranteed, a three-stage glue coating groove is arranged, the role of expansion glue is fully played, assembly clearances are eliminated, the accuracy of glue coating is higher, interferences, abnormal noises and wears produced by extrusion friction are avoided, and noise reduction of an automobile is facilitated.

Description

technical field [0001] The invention relates to the technical field of automobile parts, in particular to a curved automobile front beam assembly. Background technique [0002] The front beam assembly of the car includes the roof cover and the main body of the front beam. The roof cover is the cover plate on the top of the compartment, and the front beam of the car roof is the bearing part of the car roof. It is a three-dimensional curved panel structure with high strength and good rigidity. , to ensure the load-carrying capacity of the car body to meet the requirements of body collision regulations, the front beam of the car roof is fixed horizontally on the front top of the car roof, and the two are fixed by lap joints and welding. [0003] The front beam of the existing car roof is stamped by a strip steel plate to form an irregular curved panel structure that can accommodate the connectors. The front and rear edges of the mounting plate are overlapping edges. Closely at...

Problems solved by technology

[0004] The object of the present invention is to provide a curved front beam assembly for automobiles. In order to overcome the above-mentioned existing automobile roof front beam, the irregular curved panel structure that can accommodate the connectors is formed by stamping strip steel plates. The front and rear edges of the mounting plate are lapped When installing, it is required that the edge and the overlapping edge part be close to the roof of the car body, and the roof of the car body is usually arched, and the machining accuracy of the edge of the rear beam of the car roof is difficult to achieve a curved surface structure that matches the roof of the car body , often interferes with the roof of the car body, forming an assembly gap, which is not conducive to welding, and due to the existence of the assembly gap, it is easy to cause the rear beam of the car roof to vibrate with the car, and the extrusion friction between the roof and the car body roof will produce abnormal noise and wear , which is not conducive to the noise reduction of the car; at the same time, a roof rack is generally installed on the roof cover, but the existing roof rack is cumbersome to install, and the installed roof rack is relatively low in firmness, and it is easy to appear on the bumpy road section of the car. The shaking affects safe driving; at the same time, the existing roof rack and roof are prone to collapse in the event of an accident, causing technical problems to the passengers and drivers in the car
