Description

Technical Field

[0001] This utility model relates to the field of automotive steering wheel horn technology, and in particular to a steering wheel airbag horn contact structure. Background Technology

[0002] Most current car horn switches use a floating airbag cover design. This typically consists of several upper contacts on the airbag cover, several horn springs between the airbag and the steering wheel, and several lower contacts on the steering wheel frame. To achieve conductivity between the upper contacts, a one-piece stamped contact sheet (suitable for injection-molded airbag brackets) or a sheet metal airbag bracket with riveted contacts is generally used. The lower contacts are usually achieved by adding contact posts to the steering wheel frame and riveting copper contacts. However, this method has the following technical problems: 1. Poor conductivity between contacts; 2. Excessive waste material from the one-piece stamped contact sheet; 3. Insulation issues between the upper contacts and the horn springs; 4. The contact posts are too high.

[0003] Therefore, through beneficial exploration and research, the applicant has found a solution to the above problems, and the technical solution to be introduced below is the result of this research. Utility Model Content

The structure is characterized by further including an airbag bracket disposed on an airbag cover, an upper contact piece disposed on the airbag bracket and cooperating with the lower contact, and a horn spring disposed on the airbag bracket and rebounding when in contact with the steering wheel frame.

[0007] In a preferred embodiment of the present invention, the airbag support is provided with a plurality of support contact mounting posts for supporting the upper contact piece, each support contact mounting post having a cylindrical structure and being spaced apart on the upper surface of the airbag support.

[0008] In a preferred embodiment of the present invention, the airbag bracket is further provided with a plurality of bracket spring anti-detachment structures for preventing the horn spring from dislodging, and two bracket spring anti-detachment structures are provided on both sides of each bracket contact mounting post.

[0009] In a preferred embodiment of this utility model, the upper contact piece is provided with an upper contact boss, the upper contact boss is arranged in a "Z" shape, one end of the upper contact boss is integrally formed with the upper contact piece, and the other end of the upper contact boss cooperates with the bracket contact mounting post.

[0010] In a preferred embodiment of the present invention, the upper contact piece is further provided with a plurality of upper contact auxiliary positioning pieces that form a positioning with the airbag bracket. Each upper contact auxiliary positioning piece is arranged in an inverted "L" shape and is arranged on the side of the upper contact boss.

[0011] In a preferred embodiment of the present invention, the upper contact piece is further provided with an upper contact plug piece, and the upper contact plug piece is provided with a round hole for wire harness plugging.

[0012] Due to the adoption of the above technical solution, the beneficial effects of this utility model are as follows: This utility model uses less waste material and has a lower cost for the upper contact piece, and the mounting structure of the bracket contact mounting post and the horn spring is integrated, which simplifies the bracket structure and reduces costs; the height of the skeleton contact post is reduced, saving the use of skeleton material; and the extra space of the airbag bracket is increased, which is conducive to the miniaturization design of the airbag bracket and improves its versatility.

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below with reference to specific illustrations.

[0018] See Figures 1 to 3The diagram illustrates a steering wheel airbag horn contact structure, comprising a steering wheel frame 100, a lower contact mounting base 200 disposed on the steering wheel frame 100, and lower contacts 300 mounted on the lower contact mounting base 200. In this embodiment, there are two lower contacts 300, distributed on the left and right sides of the steering wheel frame 100. Similarly, there are also two lower contact mounting bases 200.

[0019] It also includes an airbag bracket 400 disposed on the airbag cover 1, an upper contact piece 500 disposed on the airbag bracket 400 and cooperating with the lower contact 300, and a horn spring 600 disposed on the airbag bracket 400 and rebounding when in contact with the steering wheel frame 100. In this embodiment, the upper contact piece 500 is injection molded and fixedly connected to the airbag bracket 400 by an insert.

[0020] The airbag support 400 is provided with a plurality of support contact mounting posts 410 for supporting the upper contact piece 500. Each support contact mounting post 410 has a cylindrical structure and is spaced apart on the upper surface of the airbag support 400. Specifically, there are three support contact mounting posts 410. In this embodiment, the airbag support 400 is also provided with a plurality of support spring anti-disengagement structures 420 for preventing the horn spring 600 from disengaging. Two support spring anti-disengagement structures 420 are provided on both sides of each support contact mounting post 410.

[0021] The upper contact plate 500 is provided with an upper contact boss 510, which is arranged in a "Z" shape. One end of the upper contact boss 510 is integrally formed with the upper contact plate 500, and the other end of the upper contact boss 510 mates with the bracket contact mounting post 410. To prevent positioning with the airbag bracket, the upper contact plate 500 is also provided with several upper contact auxiliary positioning pieces 520 that form a positioning with the airbag bracket 400. Each upper contact auxiliary positioning piece 520 is arranged in an inverted "L" shape and is located on the side of the upper contact boss 510. For wire harness insertion, the upper contact plate 500 is also provided with an upper contact insertion piece 530, which is provided with a circular hole 531 for wire harness insertion.

[0022] The upper contact piece 500 of this utility model unfolds into a strip structure, which allows for interlacing and arrangement during sheet metal blanking, improving material utilization. This utility model results in less waste and lower cost. Furthermore, the bracket contact mounting column is integrated with the horn spring mounting structure, simplifying the bracket structure and reducing costs. It also reduces the height of the frame contact column, saving frame material usage. Increasing the extra space of the airbag bracket facilitates the miniaturization design of the airbag bracket and improves its versatility.
