Description
Technical field
The utility model is related to technical field of automobile parts, specially a kind of noise reducing type automobile ignition switch.
Background technology
Automobile ignition switch is the subassembly that automobile enters security system, and automobile is installed on after being assembled with mechanical steering lock
On wheel steering tubing string, the lock core inward turning that when use is locked by key in mechanical steering goes to corresponding control gear to export energy
Enough electric signals understood by electronic module and relay.Wherein automobile ignition switch is usually provided with four control gears, respectively
It is OFF grades, ACC grades, RUN grades and START grades；When lock core turns to OFF grades, vehicle steering wheel is locked；Turn to ACC grades
When full vehicle be powered, radio, car light etc. can be used normally but air-conditioning cannot use；Turn to RUN at that time full vehicle in addition to opening
Remaining infrastructure device of motivation is opened；The START grades of startup gears for automobile engine are sent out when lock core turns to START grades
Motivation starts, and vehicle launch rear lock core can automatically return to RUN grades.Although existing traditional automotive ignition, which is opened, can meet above-mentioned base
This functional requirement, but there is a problem of operating handle comfort difference in use, noise is asked when especially lock core rotates
It inscribes especially prominent.
Utility model content
In view of the above-mentioned problems, the utility model provides a kind of noise reducing type automobile ignition switch, traditional igniting can be solved
Switch the problem that existing noise is big during operating with.
Its technical solution is a kind of noise reducing type automobile ignition switch comprising shell, rotating assembly, shrapnel component and base
Plate, the shell fastening are installed on the substrate, are rotatably mounted in the inner cavity that the shell is formed with the substrate
The rotating assembly, the shrapnel component are pressed between the rotating assembly and substrate and can realize the conducting of electric signal, institute
It states and a pair of of radial spring is symmetrically installed in rotating assembly, the outboard end of the radial spring is equipped with steel ball, the shell
Inner peripheral surface is equipped with shift structure, rotating assembly steel ball described in rotation process energy under the action of the radial spring
The switching for realizing different stalls is contacted with the shift structure, it is characterised in that：The shell includes POM enclosure bodies and two
TPE gear modules, respectively integrally formed with the shift structure in described two TPE gear modules, the POM enclosure bodies with
The TPE gear modules are integrally formed by quadric injection mould.
The beneficial effects of the utility model are：Its use POM enclosure bodies and TPE gear modules by quadric injection mould at
The structure that type is integrated, since TPE gear modules have excellent high resiliency, high intensity, high resilience and reliable and stable, to
Can make the rotating assembly of ignition switch in the switching of shell shift structure in more smooth-going, low noise, opened to reduce igniting
Close the noise generated when rotating gear.

Part, 21- radial springs, 22- steel balls, 30- shrapnel components, 40- substrates.
Specific implementation mode
See Fig. 1~Fig. 5, a kind of noise reducing type automobile ignition switch of the utility model comprising shell 10, rotating assembly 20,
Shrapnel component 30 and substrate 40, the fastening of shell 10 is installed on substrate 40, rotatable in the inner cavity that shell 10 is formed with substrate 40
Ground is equipped with rotating assembly 20, and the press fitting of shrapnel component 30 is between rotating assembly 20 and substrate 40 and can realize leading for electric signal
It is logical, a pair of of radial spring 21 is symmetrically installed, the outboard end of radial spring 21 is equipped with steel ball 22, shell in rotating assembly 20
10 inner peripheral surfaces are equipped with shift structure, and steel ball 22 can be with shelves under the action of radial spring 21 in rotation process for rotating assembly 20
The switching of different stalls is realized in bit architecture contact；Shell 10 include POM enclosure bodies 11 and two TPE gear modules 12, two
Pass through two integrally formed with shift structure 121, POM enclosure bodies 11 and two TPE gear modules 12 respectively in TPE gear modules
It is secondary to be integrally formed.
The automobile ignition switch of the utility model uses the POM (polyformaldehyde) with high intensity, high rigidity, high abrasion
Ontology of the plastics as shell ensures that automobile ignition switch meets the intensity used, wear-resisting requirement；And integrally formed with gear knot
The TPE gear modules 12 of structure, then since it is with high intensity, the thermoplastic elastomer (TPE) material of high resilience, when operation gear
When turning to ACC grades, RUN grades or START grades from OFF grades, steel ball 22 runs past the respective notch knot of TPE gear modules 12
Structure can absorb noise since the material of TPE gear modules 12 is flexible thermoplastic, and stability is preferable, so
Noise can be effectively reduced, operating handle is improved.Simultaneously as TPE materials have can injection molding characteristic, therefore TPE moulds
Block 12 can be easily integrated with 11 injection molding of POM enclosure bodies, to effectively reduce its difficulty of processing, improve processing effect
Rate.
The above is only a kind of preferred embodiment of the utility model.It should be pointed out that for the art
For those of ordinary skill, without deviating from the technical principle of the utility model, similar structure can also be made and set
Meter, these similar structures and design also should be regarded as the scope of protection of the utility model.
