Abstract
The invention relates to a switching mechanism, in particular to a switching mechanism of a truck steering-wheel horn. The switching mechanism of the truck steering-wheel horn comprises a steering-wheel body, wherein a horn cover is arranged on the steering-wheel body; the switching mechanism is arranged in the steering-wheel body; a spline is sleeved outside a guide pipe column; an insulation sleeve is sleeved outside the spline; the insulation sleeve and the steering-wheel body are mutually fixed; a conducting rod is inserted in a connecting sheet; a conducting rod spring is sleeved on the conducting rod; the conducting rod is inserted in the insulation sleeve; a friction plate is in sleeve connection with the guide pipe column and is arranged below the spline; a conductive contact at the bottom of the conducting rod corresponds to the friction plate; a buffer groove is arranged at the back face of the horn cover; a buffer spring is arranged in the buffer groove; the other end of the buffer spring is in contact with the connecting sheet; a horn line is connected on the connecting sheet; and a power line is connected on the friction plate. The switching mechanism of the truck steering-wheel horn has a simple structure and has the advantages of increasing the product reliability and reducing the production cost.
Description
Technical field
Patent of the present invention relates to a kind of switching mechanism, relates in particular to a kind of truck steering wheel horn switch mechanism.
Background technology
Present traditional truck steering wheel, the loudspeaker live wire all adopts conducting rod and friction plate in the steering wheel, there is spring to withstand friction plate in the conducting rod, conducting rod rotates with steering wheel, and long-term friction causes the conducting rod weak point that rubs, even it is logical to rub, cause loose contact to cause loudspeaker not ring, reduce greatly to useful life, need regular repairing or replacing.Increased use cost, influence simultaneously is normal to be used.
Summary of the invention
The present invention solves the deficiencies in the prior art, providing a kind of directly utilizes guide rod and friction plate contact point to replace horn switch on switch, when steering wheel rotates, conducting rod and friction plate are separated, the truck steering wheel horn switch mechanism that conducting rod and contact friction sheet just contact in the time of need pinning loudspeaker.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals:
A kind of truck steering wheel horn switch mechanism, comprise steering wheel main body, described steering wheel main body is provided with horn hood, be provided with switching mechanism in the described steering wheel main body, described switching mechanism comprises the guiding tubing string, friction plate, conducting rod, spline, insulating case, brace, conducting rod spring and buffering spring, described guiding tubing string overcoat has spline, described spline is with insulating case outward, described insulating case and steering wheel main body fix, described conducting rod is pegged graft in the brace, be with the conducting rod spring on the conducting rod, described conducting rod is pegged graft in the insulating case, and described friction plate socket-connects with the guiding tubing string, and described friction plate is positioned at the below of spline, the conductive contact of described conducting rod bottom is corresponding with friction plate, the back side of described horn hood is provided with dashpot, is provided with buffer spring in the described dashpot, and the other end of described buffer spring touches mutually with brace, be connected with horn wire on the described brace, be connected with power line on the described friction plate.
Simple in structure, when loudspeaker were pressed, buffer spring drove brace to pressing down, and brace presses down and makes conducting rod to pressing down, and makes conductive contact contact with friction plate, and loudspeaker are sounded.Unclamp loudspeaker, conducting rod spring return, buffer spring is return also, makes conductive contact separate with friction plate.Improved the life-span of using greatly, the reliability of at every turn honking has simultaneously improved.
As preferably, the end of described guiding tubing string is with packing ring, and described packing ring and insulating case are by the crimping of locking screw parent phase.
As preferably, the end of described conductive contact is semicircle shape, and the cross section of described insulating case is " T " shape.
As preferably, described conduction tubing string and spline are interference fit.
Therefore, a kind of truck steering wheel horn switch mechanism of the present invention, simple in structure, improve product reliability, reduce production costs.
