Description

Automobile horn sounding mechanism

Technical Field

The utility model relates to a car steering wheel is according to sounding technical field, is applied to the automotive industry, concretely relates to car horn is according to sounding mechanism.

Background

The steering wheel currently on the market comprises three parts: the horn switch-on mainly comprises an air bag cover, a middle part and a framework part, wherein the horn switch-on is realized by pressing the air bag cover to trigger a switch-on conducting loop so as to make the horn sound. The intermediate portion generally functions to support the airbag cover and to allow the circuit to conduct when depressed.

Currently, there are three types of implementation of the middle part:

the first type is that the loop is conducted on the air bag cover, the middle part is only supported by a spring, the structure is low in cost, but the air bag cover and the loop are conducted to form an integrated structure, the reject ratio is high in the actual production process, the state is unstable, the gap fluctuation of the conduction according to the sound in the actual application process is large, and the normal sound of a loudspeaker or the interference is often generated to cause the non-sound.

The second type is that the main body of the middle part adopts a metal plate structure, which has relatively good structural stability but high manufacturing cost.

The third type is that the middle part adopts the wire inserts structure, mainly by embedding wire spare, lower embedded wire spare, spring constitution, upper and lower embedded wire spare is spacing, can not throw off by self trip and draw-in groove respectively, and the spring support is placed to the centre, when receiving the power value to press, the wire contact of upper and lower embedded wire spare makes the return circuit switch on, and loudspeaker sound. The structure has the advantages of comprehensive cost and stability, the production cost is much lower than that of the second structure, the cost is slightly higher than that of the first structure, and the stability is higher than that of the first structure.

The third type of ring mechanism has relative advantages in cost and stability, but has slight disadvantages with higher and higher market competition, use requirements and cost reduction requirements. The steering wheel has improved requirements on the whole sounding conduction gap, the gap is realized by the cooperation of the airbag cover and the sounding, the cooperation of the sounding and the framework and the cooperation of the airbag cover and the framework, and the current sounding mechanism per se has difficulty in meeting the whole steering wheel conduction gap and has other part matching requirements.

The disadvantages that appear from the click mechanism currently in use are mainly:

1. the upper and lower embedded metal wire pieces of the current ringing mechanism cause the part deformation caused by the uneven demoulding shrinkage of products due to the problem of embedding metal pieces, so that the ringing stroke fluctuation is large, and the higher and higher use requirements can not be met.

2. In the face of the cost reduction requirement of the automobile industry, the cost of the current ringing mechanism is not obvious.

3. The current mechanism of pressing the sound is because upper and lower piece is overall structure, and it is not the vertical direction that to lead to upper and lower piece motion to drag the fact each other between the three point to lead to upper and lower piece friction big, the abnormal sound is big. At present mainly rely on smearing lubricating grease and fall making an uproar, use lubricating grease has two drawbacks: the first adds to the overall cost and the second affects the part VOC requirements.
