Abstract

The utility model discloses a floating loudspeaker bracket for a steering wheel, and relates to a floating loudspeaker of the steering wheel. The floating loudspeaker bracket for the steering wheel mainly solves the problem of ring block. The floating loudspeaker bracket for the steering wheel comprises an upper bracket, a lower bracket and a bolt. A conductive contact is formed on the lower surface of the upper bracket, and a corresponding conductive contact is further formed on the upper surface of the lower bracket. The upper and the lower brackets are provided with connecting through holes. The floating loudspeaker bracket for the steering wheel is characterized in that a nut is provided with a boss, the nut is welded on the outer surface of the upper bracket, and the boss on the nut is embedded in the through hole of the upper bracket and welded with the inner wall of the through hole of the upper bracket. A ring of limiting convex shoulder is arranged on the bolt which passes through the connecting through hole of the lower bracket and is fixedly arranged on the nut. The limiting convex shoulders on the bolt lean against the inner surface of the upper bracket. A loudspeaker spring is sleeved with the bolt, and a spring collar is arranged between the loudspeaker spring and the upper bracket. An insulating ring is arranged between the loudspeaker spring and the lower bracket. An insulating cushion is arranged between the head of the bolt and the lower bracket. The floating loudspeaker bracket for the steering wheel provided by the utility model is used for steering wheels.

Description

Vehicle steering floating loudspeaker support

Technical field

The utility model relates to the vehicle steering floating loudspeaker, especially relates to a kind of vehicle steering floating loudspeaker support.

Background technology

Present existing vehicle steering floating loudspeaker support (as depicted in figs. 1 and 2), by upper bracket, lower bracket and bolt form, the lower surface of upper bracket has conductive contact, the lower bracket upper surface also has corresponding conductive contact, has connecting through hole on upper bracket and the lower bracket, both are connected and fixed by 4 bolts, has boss on the nut, nut-welding is on the outside face of upper bracket, boss on the nut is embedded in the through hole of upper bracket, and weld mutually with the inwall of upper bracket through hole, has the spacing convex shoulder of a circle on the bolt, bolt is fixed on the nut after passing the connecting through hole of lower bracket, spacing convex shoulder on the bolt withstands on the boss of nut, and cover has the loudspeaker spring on the bolt, has spring collar between loudspeaker spring and the upper bracket, have insulated ring between loudspeaker spring and the lower bracket, bolt is by insulation spacer and insulated ring and lower bracket insulation.During use, press upper bracket, so that the conductive contact on the upper bracket and the conductive contact on the lower bracket are conducted, loudspeaker are switched on and are blown a whistle, after the relieving, upper bracket is upspring under the effect of loudspeaker spring and is resetted, so that the conductive contact on the upper bracket disconnects mutually with conductive contact on the lower bracket, loudspeaker stop to blow a whistle, and the spacing between upper bracket and the lower bracket is regulated by the position of bolt upper limit convex shoulder, simple in structure, easy to use.But, because the boss on nut and the nut is welded on the inwall of upper bracket and upper bracket through hole, so easily at the residual welding slag in the boss plane of nut, welding slag is easy-clear not, thereby so that nut boss plane be uneven, and the spacing convex shoulder on the bolt withstands on the boss of nut, so cause the locating surface of bolt to tilt, 4 bolts finally highly uneven, and squareness is bad, thereby cause the floating loudspeaker support to press clamping stagnation aloud, affect the function of blowing a whistle of loudspeaker.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of vehicle steering floating loudspeaker support, solves the defective that existing vehicle steering floating loudspeaker support is pressed clamping stagnation aloud.

The technical scheme that its technical matters that solves the utility model adopts is: vehicle steering floating loudspeaker support comprises upper bracket, lower bracket and bolt, the lower surface of upper bracket has conductive contact, the lower bracket upper surface also has corresponding conductive contact, has connecting through hole on upper bracket and the lower bracket, both are bolted fixing, it is characterized in that: have boss on the nut, nut-welding is on the outside face of upper bracket, boss on the nut is embedded in the through hole of upper bracket, and weld mutually with the inwall of upper bracket through hole, has the spacing convex shoulder of a circle on the bolt, bolt is fixed on the nut after passing the connecting through hole of lower bracket, spacing convex shoulder on the bolt withstands on the inside face of upper bracket, cover has the loudspeaker spring on the bolt, has spring collar between loudspeaker spring and the upper bracket, has insulated ring between loudspeaker spring and the lower bracket, have insulation spacer between the head of bolt and the lower bracket, have insulated ring between the screw rod of bolt and the lower bracket.

The beneficial effects of the utility model: because the utility model adopts the spacing convex shoulder on the bolt to withstand on the inside face of upper bracket, planeness on this plane is stable, and welding slag is easily removed, its planeness easily guarantees, the location of bolt is reliable, guaranteed the squareness of bolt, thus the upper bracket of floating loudspeaker support press with upspring reset smooth and easy, reliable.
