Switching mechanism of truck steering-wheel horn

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 [0001] The patent of the present invention relates to a switch mechanism, in particular to a truck steering wheel horn switch mechanism. Background technique [0002] At present, the traditional truck steering wheel and the horn wire in the steering wheel use a conductive rod and a friction plate. There is a spring in the conductive rod to withstand the friction plate. Defects cause the horn to not sound, and the service life is greatly reduced, requiring frequent repairs or replacements. Increased use cost, affects normal use simultaneously. Contents of the invention [0003] The present invention mainly solves the deficiencies in the prior art, and provides a switch that directly uses the contact point of the guide rod and the friction plate to replace the horn switch. The horn switch mechanism of the truck steering wheel before the rod comes into contact with the contact friction plate. [0004] Above-mentioned technical problem of the presen...
