The utility model provides a push switch, press the driving medium after, touch PCBA, unexpected when leading to the fact the pressing force to surpass the biggest restriction that a coil spring can bear when appearing, the PCBA elasticity of compression spare that can step forward, the elastic component is through the ulcerate energy -absorbing that contracts to make push switch have anticollision function, can protect each components and parts.
Description
Technical field
This utility model is related to electric switch field, more particularly, to a kind of button switch.
Background technology
At present, the commonly used light-touch botton switch of the button switch on elevator, its touch pressure is between 2.5N-5N.With
Elevator applications scope is more and more wider, and the elevator installed in some special occasions requires increasingly to the collision prevention function of button switch
Height, existing light-touch botton switch can lead to switching damage to lose efficacy when touch pressure is excessive, the operation safety of impact elevator.
Utility model content
The purpose of this utility model is to provide one kind to have a collision prevention function, more safe and reliable button switch.
For reaching this purpose, this utility model employs the following technical solutions：
A kind of button switch, it includes housing, is placed in driving member, the first spiral that this outer inframe sets gradually from top to bottom
Spring, PCBA, escutcheon on described housing for the buckle closure, through hole from this escutcheon for the described driving member passes.This button is opened
Close and also include multiple elastic components, these elastic components are placed in described outer inframe and uniformly arrange, be applied to described PCBA for absorbing
On pressure；The elastic force of described first helical spring is less than the elastic force of described elastic component.
Preferably, described elastic component is the second helical spring, one end of each described second helical spring is resisted against institute
State inside the bottom of housing, the other end is resisted against described PCBA towards on the bottom surface of described housing bottom.
Preferably, described button switch also includes：
Multiple locating dowels, it is fixed on inside the bottom of described housing and uniformly arranges, each described second helical spring
It is sleeved in locating dowel described in.
Preferably, described button switch also includes：
Letter plate, its back side is fixed on described driving member from the end face that the through hole of described escutcheon passes.
Preferably, the back side of described letter plate is fixed with least one steel ball, described steel ball be embedded in described driving member from
On the end face that the through hole of described escutcheon passes.
Button switch provided by the utility model, after lower transmission component, touches PCBA, causes pressing force when appearance is unexpected
More than the first helical spring can bear maximum limit when, PCBA can further compression elastic piece, elastic component inhaled by crumple
Can, so that button switch is provided with collision prevention function, each components and parts is protected.
Brief description
Fig. 1 is the explosive view of the button switch that this utility model embodiment provides.
In figure：1- escutcheon, 2- letter plate, 3- driving member, 4- first helical spring, 5-PCBA, 6- second helical spring,
7- housing.
Specific embodiment
Further illustrate the technical solution of the utility model below in conjunction with the accompanying drawings and by specific embodiment.
As shown in figure 1, a kind of button switch, it includes housing 7, is placed in the biography set gradually from top to bottom in this housing 7
(PCBA is the abbreviation of English Printed Circuit Board+Assembly, also for moving part 3, the first helical spring 4, PCBA5
It is to say PCB hollow plate through SMT upper part, abbreviation PCBA, this is a kind of domestic conventional literary style), escutcheon on housing 7 for the buckle closure
1, through hole from this escutcheon 1 for the driving member 3 passes.This button switch also includes multiple elastic components, and these elastic components are placed in outer
Arrange in frame 7 and uniformly, in the present embodiment, as shown in figure 1, for the ease of drawing materials, elastic component is preferably the second helical spring
6, certainly, also can be selected for leaf spring or polyurethane spring etc..One end of every one second helical spring 6 is resisted against in the bottom of housing 7
Side, the other end is resisted against PCBA5 towards on the bottom surface of housing 7 bottom.The elastic force of the first helical spring 4 is less than the bullet of elastic component
Power.
Traditional button switch PCBA is immovable, and external force directly acts on button switch, if pressing force mistake
Impact force big or that appearance is excessive will be damaged button by pressure.And the button switch that the present embodiment provides, after lower transmission component 3, touch
Dynamic PCBA5, the normal work of achievable button switch.When accident collision occurring or pressing force is excessive, lead to pressing force more than
During the maximum restriction that one helical spring 4 can bear, PCBA5 can compress the second helical spring 6, the second helical spring 6 further
By crumple energy-absorbing, so that button switch is provided with collision prevention function, each components and parts is protected.In addition, in order to right
Driving member 3 pushes the second helical spring 6 and is any limitation as, and can arrange limiting stand, so, accidental impact power or excessive in housing 7
Pressing force can pass to the second helical spring 6 through PCBA5, after driving member 3 touches described limiting stand, whole crumple is inhaled
Can process terminate, thus protecting each part in button switch not to be subject to crushing.
Positioning in view of the second helical spring 6 and the steady problem placed, then it is further preferred that in housing 7
Multiple locating dowels are fixed, these locating dowels are uniformly arranged inside the bottom of housing 7, every one second helical spring 6 inside bottom
It is sleeved in a locating dowel.
The function to be realized in order to clearly show button switch, then, as shown in figure 1, in the present embodiment, button
Switch also includes a letter plate 2, and this letter plate 2 back side is fixed on driving member 3 from the end face that the through hole of escutcheon 1 passes, can
The function that this button switch is realized is indicated on this letter plate 2.In order to prevent letter plate 2 from rotating or rock, even more important
, prevent letter plate 2 from falling off, then, it is further preferred that the back side of letter plate 2 is fixed with after being subject to frontal impact
At least one steel ball, steel ball is embedded in driving member 3 from the end face that the through hole of escutcheon 1 passes, and steel ball is by letter plate 2 and driving member
3 lockings, so that will not occur relative movement between the two.Certainly, those skilled in the art also may be selected in letter plate 2
Back side fixing screws, screw is embedded in driving member 3 from the end face that the through hole of escutcheon 1 passes, to prevent letter plate 2 from coming off.
Obviously, above-described embodiment of the present utility model is used for the purpose of clearly this utility model example being described, and
It is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, in described above
On the basis of can also make other changes in different forms.There is no need to give to all of embodiment
Exhaustive.All any modification, equivalent and improvement made within spirit of the present utility model and principle etc., should be included in
Within this utility model scope of the claims.
