Description

Connection structure and vehicle

Technical Field

The utility model relates to the technical field of vehicle parts, in particular to a connecting structure. Meanwhile, the utility model also relates to a vehicle adopting the connecting structure.

Background

With the flourishing development of the automobile industry, competition among automobile enterprises is increasingly strong, and low-cost structural design is an important route for improving the competitiveness. The vehicle body is a mounting foundation of the whole vehicle and integrally comprises main bearing elements such as longitudinal beams, cross beams, struts and the like, and sheet metal parts connected with the main bearing elements. It is therefore important to optimize the body structure to improve the body performance.

The parts on the vehicle body are more, and when the parts are connected, the connection scheme adopted generally mainly comprises two connection modes of direct welding and reinforcing plate matching. For example, when the end of one member is directly welded to the side of the other member, the joint between the two members may be welded. The direct welding connection mode is convenient to operate and low in cost.

However, the disadvantage of direct welding is that only the linear position where the two parts meet is welded, so that the strength of the connection between the two parts is low. Especially, when the direct welded connection structure is applied to an important connection part and a vehicle collides and the like receives external impact force, the connection failure easily occurs at the welding part, so that the connection effect of the two parts is poor, even the connection is released, and the safety of the vehicle body is further influenced. In addition, the welding process has the problems of component deformation, environmental pollution and the like.

The scheme of direct welding and reinforcing plate matching means that after two parts are connected in a direct welding mode, the reinforcing plate is arranged on the outer side of the joint of the two parts, and the reinforcing plate is connected with the two parts through a connecting piece at the same time, so that the connection strength is improved. However, the scheme of adopting the reinforcing plate to improve the strength increases the reinforcing plate and the connecting piece, thereby increasing the number of parts, increasing the material cost and being unfavorable for the low-cost design of the vehicle body. Meanwhile, the arrangement of the reinforcing plate and the connecting piece also enables the appearance of the connecting part to be attractive, and is not beneficial to the delicacy of the vehicle body.
