Connecting structure of stiffening beam and side wall assembly on front wheel cover

Abstract

The invention provides a connecting structure of a stiffening beam and a side wall assembly on a front wheel cover, which solves the problem of CO2 welding spot breaking or part metal plate cracking in a traditional structure, improves the safety of a bicycle body and the satisfaction degree of a customer, and lowers the manufacturing cost of a bicycle. The connecting structure comprises a front wheel cover stiffening beam, a side wall outer plate, a column-A lower stiffening plate and a column-A upper hinge stiffening plate which are sequentially fit from outside to inside, wherein the column-A lower stiffening plate and the column-A upper hinge stiffening plate are connected through spot welding to form a column-A lower stiffening plate assembly; the column-A upper hinge stiffening plateis provided with a welding through hole; and the front wheel cover stiffening beam, the side wall outer plate and the column-A lower stiffening plate assembly are connected together and are connectedby virtue of spot welding through the welding through hole by using welding tongs.

Description

technical field [0001] The invention relates to the technical field of automobile body structures, in particular to a connection structure between a reinforcement beam on a front wheel cover and a side wall assembly. Background technique [0002] At present, the reinforcing beam on the front wheel cover of the automobile is in the final process of the skeleton, and the CO 2 welded together. Its structure is as figure 1 and figure 2 As shown, the upper hinge reinforcement plate 3 of the A-pillar and the lower reinforcement plate 4 of the A-pillar are connected by spot welding to form the lower reinforcement plate assembly of the A-pillar, and the lower reinforcement plate assembly of the A-pillar and the outer panel of the side wall are realized through the joint a of the three-layer plate spot welding connection to form the side wall outer panel assembly, where the three-layer plate welds are the A-pillar upper hinge reinforcement plate 3, the A-pillar lower reinforcemen...
