Problems solved by technology
However, after the welding of the car longitudinal beam is completed, there are certain welding errors along the vehicle width direction in the two left and right car longitudinal beams formed to overhang the vehicle length direction, resulting in that the front end of the car longitudinal beam cannot be connected with the water tank riser plate. Unfavorable phenomenon that cannot be connected due to the precise abutment of the surface

Embodiment Construction
[0013] combine Figure 1 to Figure 8 , the present invention is further described:
[0014] A front-end frame structure of an automobile, comprising upper and lower water tank beams 10 parallel to the vehicle width direction and left and right water tank risers 20 arranged vertically, the upper and lower water tank beams 10 and left and right water tank risers 20 are connected to form a The overall rectangular frame structure, the vehicle longitudinal beam 30 arranged along the vehicle length direction extends to the outer surface of the water tank riser 20, the inner surface of the vehicle longitudinal beam 30 is close to the outer surface of the water tank riser 20 and the gap is set, the vehicle vertical The beam 30 is transitionally connected to the water tank riser 20 through a connecting piece.
[0015] A gap is set between the inner side of the car longitudinal beam 30 and the outer side of the water tank riser 20, and the fastening connection between the two is realiz...

The invention belongs to the technical field of automobile body sheet metal structures, and particularly relates to an automobile front-end frame structure, which includes upper and lower water tank beams parallel to the vehicle width direction, left and right water tank risers vertically arranged, upper and lower water tank beams and The overall rectangular frame structure formed by the connection of the left and right water tank risers, the car longitudinal beam arranged along the vehicle length extends to the outer surface of the water tank riser, the inner side of the car longitudinal beam is close to the outer surface of the water tank riser Gap setting, the car longitudinal beam and the water tank riser are connected through a transitional piece, and a sufficient assembly gap is reserved between the car longitudinal beam and the water tank riser to ensure that the front end of the car longitudinal beam can be welded and assembled with the water tank riser. Corrected the disadvantages that the welding error of the longitudinal beam of the car caused it to be unable to be assembled on the front frame or the assembly accuracy was low.
Description
technical field [0001] The invention belongs to the technical field of automobile body sheet metal structures, in particular to an automobile front-end frame structure. Background technique [0002] In the traditional car body structure, the front frame includes the upper and lower water tank beams parallel to the vehicle width direction. The two ends of the upper and lower water tank beams are provided with left and right water tank risers, left and right water tank risers and upper and lower water tanks. The crossbeams constitute a rectangular frame structure for loading automotive cooling modules, headlights, water tanks and other components. The left and right water tank vertical plates are respectively connected to the front ends of the left and right longitudinal beams, thus forming an overall car front-end frame structure. [0003] In the front-end frame structure of a traditional car, the connection method between the water tank vertical plate and the vehicle longitu...
