Description
Technical field
The present invention relates to automobile air conditioning technology field, more particularly to a kind of automotive air-conditioning controller press button mechanism.
Background technology
Existing automotive air-conditioning controller press button mechanism, it realizes that general structure is：Key body is arranged on housing from front
On, limit pressing movement stroke by several cantilever grabs.The shortcoming of the press button mechanism is：1st, noise is big during button, and influence is driven
The comfort for the person of sailing；2nd, in order to reduce noise during button operation, grab wall thickness can be relatively thin, clamping of the grab on housing
Power is also weaker, like this when controller front is by greater impact, and grab can slip that to cause key body to be come off from housing winged
Go out.
The content of the invention
The technical problems to be solved by the invention are that there is provided a kind of automotive air-conditioning controller in view of the shortcomings of the prior art
Press button mechanism, key body comes off the purpose flown out from housing during reaching reduction button noise, avoid being subjected to impact.
In order to solve the above technical problems, the technical scheme is that：A kind of automotive air-conditioning controller press button mechanism, including
Housing, key body, key switch, circuit board, the periphery of the outer wall bottom of described key body, which is extended with, to be stretched under inner walls
Hook structure in portion's groove, the position limiting structure that described inner walls are moved provided with limitation key body to outside housing.
The position limiting structure of described inner walls is the limited wall stretched out by inner walls, forms the step-like knot of inner walls
Structure.
The outer wall of described key body is the step-like structure that shape is adapted with inner walls shape, described key body
Outer wall and inner walls between be provided with gap.
Connected between the limited wall of described housing and the corresponding position of housing by spring assembly.
Described spring assembly includes multiple springs, and the limited wall that each spring one end stretches into housing is fixed, and spring is another
End is stretched into key body outer wall and fixed.
Described spring is three, triangular shape arrangement.
The coupler body of described grab is stretched into inner walls lower channel, and the coupler body end of grab is arc body.
Described key body upper end is provided with button cap, and described button cap periphery, which is extended with, is wrapped in key body upper end outer wall
On shade, described shade stretched into the key hole of housing, and the inner face of described button cap is by multiple fixing muscles with pressing
Key body is connected.
Between being provided between described shade and key body upper end outer wall on gap, described shade inwall described in being communicated with
The annular groove of gap.
The cell wall of the annular groove of described shade inwall is provided with multiple pits.
The present invention uses said structure, with advantages below：1st, size is big below key body, top size is small, it is ensured that press
Key body can only be installed from back side of shell, and key body can not be from the back side integrally through housing key hole.Pass through the grab on key body
The movement travel of control button body, key body is strictly controlled with housing motion direction gap.This gap was both ensureing button just
Often during operation, key body does not have other parts and touches housing in addition to grab, reduces noise；2nd, controller front is subjected to impact
When, grab has certain deflection in groove, spring assembly compression, alleviates impulsive force, prevent grab because impulsive force is excessive and
Come off, it is to avoid key body flies out, after impacting and terminating spring assembly restoring force and grab recoverable force power effect under by
Key body automatically restores to normal operation position；3rd, when button in use, the noise that button is produced passes through shade and key body upper end
Gap between outer wall is reached in annular groove, is digested in the space of annular groove and on cell wall in multiple pits, greatly
The big outflow amount for reducing button noise, improves comfort.

Embodiment
A kind of automotive air-conditioning controller press button mechanism as shown in Figure 1, including housing 1, key body 2, key switch 3, circuit
Plate 4, the periphery of the outer wall bottom of key body 2 is extended with the structure of grab 5 stretched into the inner wall lower groove of housing 1, the inwall of housing 1
The position limiting structure moved provided with limitation key body 2 to outside housing 1.The position limiting structure of the inwall of housing 1 is to be stretched out by the inwall of housing 1
Limited wall 6, formed inner walls step-like structure.
The outer wall of key body 2 is the step-like structure that shape is adapted with the inner wall shape of housing 1, the lower section size of key body 2
Greatly, top size is small, it is ensured that key body 2 can only be installed from the back side of housing 1, and key body 2 can not be pressed from the back side integrally through housing 1
Keyhole, the structure ensure that controller when being hit power, and key body 2 will not fly out.The outer wall of key body 2 and the inwall of housing 1
Between be provided with gap, it is ensured that during button normal operating, key body 2 does not have other parts and touches housing 1 in addition to grab, reduce
The noise produced by friction.
Connected between the limited wall 6 of housing 1 and the corresponding position of housing 1 by spring assembly 7.Spring assembly 7 includes multiple
Spring, the limited wall 6 that each spring one end stretches into housing is fixed, and the spring other end stretches into the outer wall of key body 2 and fixed.Spring is three
It is individual, triangular shape arrangement.Triangle arrangement ensure that stability of strutting system.When controller front is subjected to impact, grab 5 is in ditch
There is certain deflection in groove, spring assembly 7 compresses, alleviate impulsive force, prevent grab 5 from being come off because impulsive force is excessive, it is to avoid
Key body 2 flies out, after impacting and terminating spring assembly 7 restoring force and grab 5 recoverable force power effect under key body 2 from
It is dynamic to return to normal operation position.
The coupler body of grab 5 is stretched into the inner wall lower groove of housing 1, and the coupler body end of grab 5 is arc body, controller by
To during impact, arc body reduces the frictional force that the active force between the end of grab 5 and the inner wall lower groove of housing 1 is produced, it is to avoid
Abrasion.
The upper end of key body 2 is provided with button cap 8, and the periphery of button cap 8 is extended with the shade being wrapped on the upper end outer wall of key body 2
9, shade 9 is stretched into the key hole of housing 1, and the inner face of button cap 8 is connected by multiple fixing muscles 10 with key body 2.Shade 9
The annular groove 11 that the gap is communicated with gap, the inwall of shade 9 is provided between the upper end outer wall of key body 2.In shade 9
The cell wall of the annular groove 11 of wall is provided with multiple pits.
When button in use, button can still produce noise, and noise passes through shade 9 and key body 2 in outside transmission
Gap between the outer wall of upper end is reached in annular groove 11, is entered in the space of annular groove 11 and on cell wall in multiple pits
Row digestion, greatly reduces the outflow amount of button noise, and driver will be barely audible button noise, improve comfort.
The present invention is exemplarily described above in conjunction with accompanying drawing, it is clear that the present invention is implemented not by aforesaid way
Limitation, as long as employing the various improvement of technical scheme progress, or not improved directly apply to other occasions
, within protection scope of the present invention.
