Gas spring reinforcement plate for back door

Abstract

The invention provides a rear door gas spring reinforcement plate to solve the problem of small bonding surface between the traditional rear door gas spring reinforcement plate and the inner panel of the rear door, the small number of solder joints, and the problem of bumping, braking, turning and other vehicle conditions. Under the environment, it is easy to cause stress concentration, cracking and other problems. The rear door gas spring reinforcing plate is long and includes a base surface on the left. A T-shaped reinforcing rib is provided on the base surface, and a plurality of bosses are arranged on the longitudinal direction of the T-shaped reinforcing rib. The weight-reducing hole of the base surface extends a plurality of irregularly shaped welding contact feet from the left end, and the welding contact feet are provided with solder joints; , and a gas spring installation surface between the base surface and the step surface, the gas spring installation surface is provided with at least one boss installation surface concave toward the inner panel of the back door, and the boss installation surface A gas spring installation hole is provided; the gas spring installation surface and the step surface are provided with welding spots.

Description

technical field [0001] The invention belongs to the technical field of automobile manufacturing, and in particular relates to a rear door gas spring reinforcement plate. Background technique [0002] The rear door system is a relatively independent assembly in the car body structure, and it is an important channel for users to store items and escape in an emergency. The rear door gas spring is a structure that controls the opening and closing of the rear door, and is one of the more commonly used structures in automobiles. [0003] The gas spring reinforcement plate of the back door is located between the inner panel and the outer panel of the back door. From the perspective of automobile structure, it is one of the important components of the back door. The gas spring reinforcement plate is generally welded with the inner plate, as the main strengthening part connecting the gas spring and the back door, its main function is to bear the supporting force and tension of the g...
