Safety airbag clamping device mounted on automotive steering wheel

Abstract

A safety airbag clamping device mounted on an automotive steering wheel comprises an airbag case, a right sinuous snap spring, a left sinuous snap spring, four stainless steel contacts, four bolts, nuts and a gas generator. The airbag case is provided with clamping grooves and round holes. A wedged surface is arranged below each clamping groove. The left and right sinuous snap springs are disposed in the clamping grooves and clamped on the wedged surfaces. One end of each stainless steel contact is provided with a ring, the other end of the stainless steel contact is provided with an n-shaped contact, the contact of the stainless steel contact is inserted into on upper round hole of the airbag case, the airbag case is provided with reverse hooks, one reverse hook clamps the middle of the stainless steel contact, a large round hole and a small round hole are arranged on one side of a conducting plate, and the small round hole is fitted to a round projection on the airbag case. The bolts penetrate flange round holes of the gas generator, the large round holes of the conducting plates and the rings of the stainless steel contacts and are fastened via the nuts. Therefore, the safety airbag is clamped to the steering wheel better, a push-to-ring structure of a traditional speaker is changed, and the safety airbag clamping device is simple in structure and lower in cost.

Description

technical field [0001] The invention relates to a safety air bag clamping device installed on the steering wheel of an automobile. Background technique [0002] The existing airbag clamping device installed on the steering wheel of an automobile uses a whole (one) U-shaped spring placed horizontally to clamp the airbag device to the steering wheel by utilizing the deformation of the spring in the horizontal direction. With this structure, when clamping, due to the deformation of the spring in the horizontal direction, the deformation force is large, resulting in a large clamping force, and the overall U-shaped spring structure is large in size. During the transportation of parts, it is easy to bump and cause permanent deformation. Ineffective. [0003] For the horn mechanism of the steering wheel, copper sheets are generally used as contacts and fixed on the airbag device, and the function of opening and closing the horn is realized by contacting and separating the metal co...
