Embodiment Construction

[0029] figure 1 As shown, the present invention has three identical structural units, and in practical application, there may be more than three structural units, and one of the structural units will be described below. The fixed bracket 2 is installed under the support plate 1, the support spring 4 is interposed between the support plate 1 and the fixed bracket 2, the micro switch 3 is clamped in the fixed bracket 2, and the movement stroke of the support plate is greater than the touch point on the support plate The distance from the touch end of the micro switch. The wire 6 is used to connect the same structural units in parallel, and the wire harness card 5 is used to fix the wire 6 .

[0030] Such as figure 2 and image 3 As shown, the fixing bracket 2 is a plastic part, and there are buckles 2.1 and square holes 2.2 on both sides of the fixing bracket 2. The buckles 2.1 on both sides are deformed to the outside as the micro switch 3 is pressed in, and when the micro...

Abstract

A novel automobile horn sounding mechanism comprises a steering wheel decoration cover. At least three structure units which are distributed in the circumferential direction are fixedly arranged below the steering wheel decoration cover. Each structure unit is composed of a supporting plate fixedly connected with the steering wheel decoration cover, a fixed support installed below the supporting plate, a supporting spring located between the fixed support and the supporting plate and a micro-switch arranged on the fixed support. The tail ends of the supporting springs arranged on the supporting plates are triggering points, the motion stroke of the supporting plates is larger than the distance between the tail end triggering points of the supporting springs and the triggering ends of the micro-switches, and the micro-switches are connected through wires. According to the novel automobile horn sounding mechanism, the switching principle of an existing automobile steering wheel horn sounding mechanism is changed, the micro-switches which are mature in technology and long in service life are applied to the automobile horn sounding mechanism, the design of a steering wheel is simplified, the cost is lowered, the service life is prolonged, the reliability is improved, and compared with an existing horn sounding structure, the novel automobile horn sounding mechanism has cost and performance advantages.

Description

technical field [0001] The invention relates to a novel car horn clicking mechanism, which can be used on various types of car steering wheels. Background technique [0002] For the structure of the car horn on the steering wheel, generally, the steering wheel trim cover and the airbag module are fixed together. When the steering wheel trim cover is pressed, the airbag module and the metal contact at the bottom of the steering wheel are closed to form a circuit to realize the horn sounding function; for The steering wheel, in which the airbag module and the base of the steering wheel are fixed to each other, realizes the horn function by pressing the steering wheel cover up and down. In the prior art, the horn function is realized by pressing the metal reed and contacting and separating the metal wire. [0003] The existing problems are: the cost of the existing technology is high, the parts are not universal, and different steering wheel shapes require corresponding click s...
