Description

Noise reduction structure for automobile key

Technical Field

The utility model relates to a car button technical field specifically is a structure of making an uproar falls for car button.

Background

With the development of society, the living standard of people is improved, automobiles have gone into thousands of households, various switch buttons on automobile panels are one of important electrical components in automobile interior decoration, and the quality of the performance of the switch buttons directly influences the quality and the performance of the whole automobiles. Traditional automobile starting need be started through the key, and not only complex operation also can have the key to lose and the phenomenon that can't start the car, so a key start button is born along with it, but present a key start button inner structure is comparatively complicated not only, and in the use, owing to frequently using, life is low, still has certain noise in use, influences the use and feels.

Disclosure of Invention

In view of the above problem, the utility model provides a structure of making an uproar falls for car button, its simple structure, but increase of service life reduces the noise of use.

The technical scheme is that, a structure of making an uproar falls for car button, it includes the casing and assembles button, executor in the casing, the base is equipped with to the bottom in the casing, be equipped with the circuit board on the base, the button passes through the executor press contact on the circuit board, its characterized in that: the circuit board is closely assembled on the bottom surface of the connecting piece, a semicircular bulge is arranged on the contact end surface of the connecting piece, the semicircular bulge is in contact with the actuator, and the connecting piece and the semicircular bulge are made of conductive rubber materials.

It is further characterized in that:

the bottom surface of the actuator is provided with a groove, a positioning block is arranged on the contact end surface of the connecting piece corresponding to the groove, the semicircular bulge is arranged on the end surface of the positioning block, and the positioning block is positioned in the groove;

the key is characterized by further comprising a first electroplating ring and a second electroplating ring, wherein the shell is of an open structure, an annular groove is formed in the bottom surface of the first electroplating ring, the first electroplating ring is assembled at the open end of the shell through the annular groove, and the second electroplating ring is sleeved on the outer ring of the key and is positioned between the key and the first electroplating ring;

the outer wall of the shell is provided with a claw with elasticity.

The beneficial effects of the utility model are that, its simple structure is through pressing the button for the executor touches the circuit board behind the connecting piece, realizes that the button presses the start-up, realizes increase of service life, and is provided with the semi-circular arch of conductive rubber material on the connecting piece, can effective noise reduction, has better use value.
