Therefore, the housing of automobile-use rotary switch how is avoided to be the important technological problems that those skilled in the art need to solve at present with producing relative rocking with structural friction between rotating shaft.
Utility model content
The purpose of this utility model is to provide a kind of automobile-use rotary switch, the housing of this automobile-use rotary switch with not easily produce relative rocking and structural friction between rotating shaft.
For solving the problems of the technologies described above, the utility model provides a kind of automobile-use rotary switch, comprise circuit board, described circuit board is provided with knob shell, the middle part of described knob shell is coaxially arranged with annular fitting recess, coaxially be fitted with rotating shaft in described annular fitting recess, between the internal ring wall of described annular fitting recess and the inwall of described rotating shaft, be provided with rolling bearing, and described shaft bearing fits tightly respectively and between described annular fitting recess and described rotating shaft;
The top of described knob shell is provided with the knob with described rotating shaft coaxial linkage.
Preferably, the lower sidewall of described knob radially runs through some hole clippings, the periphery wall of described rotating shaft is provided with the card base of some and described hole clipping one_to_one corresponding clamping adaptation.
Relative above-mentioned background technology, automobile-use rotary switch provided by the utility model, by installing rolling bearing additional between the internal ring wall and the inwall of described rotating shaft of described annular fitting recess, and ensure that rolling bearing fits tightly with the internal ring wall of annular fitting recess and the inwall of described rotating shaft respectively, effectively eliminate exist between knob shell with rotating shaft relative to rock, and the structural friction that effectively prevent in use procedure between knob shell and rotating shaft, not only increase the integrated operation feel of described automobile-use rotary switch, also make be able to suitable raising the useful life of its relevant matable assembly.
In another preferred version of the present utility model, the lower sidewall of described knob radially runs through some hole clippings, the periphery wall of described rotating shaft is provided with the card base of some and described hole clipping one_to_one corresponding clamping adaptation.By the snap-fit engagement between card base and hole clipping, the reliable assembling between knob and rotating shaft can be ensured, and ensure that the coaxial linkage between knob with rotating shaft coordinates, and this kind of clamping assembly structure is convenient to dismounting, suitably can improve the overall efficiency of assembling of described automobile-use rotary switch.
