Specific implementation mode
The utility model is described in further detail below in conjunction with specific embodiment and attached drawing.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, in a preferred embodiment, the compound mechanical switch of sounding of the utility model
Including upper cover 1, pedestal 2 and button 3, upper cover 1 and pedestal 2 fasten installation and form cavity, and button 3 is arranged in the cavity, upper cover 1
Upper end is provided with opening 11, and 3 upper end of button is extended 1 surface of upper cover by opening 11, set between 2 inner wall of button 3 and pedestal
It is equipped with the big spring 4 in compressive state.
In this implementation, 3 lower end of button is equipped with a frizzen 31, and a through-hole 21, frizzen 31 are offered in 2 lower part of pedestal
Lower end extends 2 lower section of pedestal by the through-hole 21.In the circuit board that can be positioned below of pedestal 2, can be arranged on circuit boards
There is thin film switch structure, press button 3, frizzen 31 moves downward, and 31 lower end of frizzen is pierced by the through-hole 21, and then connects
Thin film switch structure realizes the conducting of switch.
In the present embodiment, button 3 includes that the top button 32 of upper lid surface is exposed and under top button 32 in upper end
Side fastens the lower button 33 being integrated with top button 32, and space is formed between top button 32 and lower button 33, touches
Hair bar 31 is installed on from top to bottom in lower button 33, and 31 upper end of frizzen is located in the space.The upper surface of lower button 33
It is provided with connecting rod 333, top button 32 connects with lower button 33 by connecting rod 333 is riveted on top button 32
Connect, connect or hot riveting in addition, top button 32 and lower button 33 are not limited to pin hole, also can individually hot riveting or its
He fixes at connection type, equally can reach identical technique effect.
Meanwhile it being provided between 32 lower face of 31 upper surface of frizzen and top button and being pressed for increasing frizzen 31
The elastic component 34 of stroke.By the elastic force of elastic component 34, the up and down motion of frizzen 31 is realized.It is peaked at first by frizzen 31
Thin film switch action is triggered on thin film switch structure, since the smaller elastic component 34 of elasticity can quilt after thin film switch is pressed down
Compression, button 3 can continue to push, and overtravel be formed, to increase the entire stroke of button.The structure and working method can be very big
Increase mechanical switch feel, reduce the pressure to thin film switch, can effectively protect thin film switch improves switch life, and feel is more
Add good.Also, by changing the space length between 31 upper end of frizzen and button 3, overtravel size can be adjusted, is suitble to
In the keyboard for needing different trips to require, applicability is more extensive.Elastic component 34 is spring.
Further, it is provided with the rod set 331 extended downwardly on the center of lower button 33, is set in rod set 331
It is equipped with stepped hole 332,31 upper end of frizzen is provided with the step 311 that outer diameter is more than mounting hole internal diameter.It is appreciated that frizzen 31
On step 311 coordinate elastic component 34 elastic force fix on stepped hole 332.
To make switch can make a sound, a torsional spring 5 is installed on pedestal 2,3 side wall of button be provided with from top to bottom by
Gradually it is higher than the top incline 35 of button side walls and extends from 35 lower part of top incline and be gradually less than 3 side wall of button from top to bottom
One end of bottom incline 36, torsional spring 5 extends to 36 lower section of bottom incline and is set as forced section 51, when button 3 pushes, forced section
51 stress move obliquely along bottom incline 36, skid off the rebound of bottom incline 36 and hit the sounding of realization of pedestal 2, in button 3
When rebound, 51 stress of forced section moves obliquely along top incline 35, skid off top incline 35 rebound hit pedestal 2 realize it is secondary
Sounding.In addition, forced section 51 can be the loop configuration of prolate, preferably contacted with top incline 35 or bottom incline 36.Pass through
The stroke length for adjusting the length and frizzen of frizzen can make a sound in switch conduction, improve feel.
In the present embodiment, the upper end setting fluted 37 of lower button 33,4 one end of elastic component is arranged in the groove 37
On, ensure that elastic component 34 will not shift in action, in addition, the interior electrical path length of groove 37 is just to accommodate elastic component 34
Size is advisable.Similar groove 37 is not arranged on frizzen 31 can accommodate the structure of 34 one end of elastic component, to reduce triggering
The size of bar 31 reduces the volume that frizzen 31 occupies on switch, it is ensured that has enough space installations saturating on pedestal
The structures such as mirror or LED light.
Meanwhile groove 37 is connected with stepped hole 332, the internal diameter of groove 37 is more than the internal diameter of stepped hole 332, may make triggering
Bar 31 is so smooth that be installed on from top to bottom in lower button 33.
The utility model can realize such as green axis, red axis, tea axis and the different types of keyboard switch of black axis, as Fig. 5, Fig. 6,
Shown in Fig. 7 and Fig. 8, two curves in these attached drawings are respectively the stress curve figure of backhaul and backhaul, and stress pressing test makes
With stabilization, action is smooth, meets player and selects use demand to different type keyboard switch.
The above-mentioned compound mechanical switch of sounding, under the button press or spring back when, forced section can be moved along bottom incline or
It is moved along top incline, it is real can to hit pedestal by the deformation resilience of torsional spring when skidding off top incline or skidding off bottom incline
The step of now making a sound realizes that switch conduction is synchronous with what is made a sound, simple in structure, can increase user's feel, meet not
With the demand of user.
Although the description combination embodiments above to the utility model carries out, it is familiar with the art
