Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
The utility model discloses a kind of mute keyboards, as shown in Figure 1, Figure 2 and Figure 3, including with multiple first placements
The pedestal 1 of chamber 11 and multiple first press-key structures 2.Each first placed cavity 11 has for placing the first press-key structure 2
First frame 111, the inner wall of the first frame 111 are set there are two groove 1111.Each first press-key structure 2 includes the first keycap
21, it is located at the first pressing down section 22 of 21 bottom surface of the first keycap and is located at 22 bottom surface of the first pressing down section and flexible trigger member
3,21 bottom surface of the first keycap is downwardly extending there are two the hook 23 being oppositely arranged, and each hook 23 includes being connected to the first key
The strip 231 of cap 21 and back-off 232 set on strip 231, back-off 232 are sticked in its corresponding groove 1111 and can be along correspondences
Groove 1111 slide, remain a fixed spacing between the upper end inner wall of the corresponding groove 1111 in 232 upper surfaces of back-off.
It is buckled between the upper end inner wall of the corresponding groove 1111 in 232 upper surfaces and remains a fixed spacing, in conjunction with actual condition
Concrete meaning include it is following three aspect: first, keyboard when not in use, i.e., when the first keycap 21 is not by ambient pressure,
It detains and remains a fixed spacing between the upper end inner wall of the corresponding groove 1111 in 232 upper surfaces；Second, using keyboard
When, i.e., when extraneous application pressure presses the first keycap 21, the first keycap 21 is moved down, and 232 upper surfaces of back-off are corresponding
A fixed spacing is remained between the upper end inner wall of groove 1111；Third opens the elastic force of the first keycap 21 and trigger member 3 in souththern pine
Drive the first keycap 21 be reset to it is static during, the upper end inner wall of the corresponding groove 1111 in 232 upper surfaces of back-off it
Between remain a fixed spacing.It is buckled to the setting of the spacing between 232 upper surfaces and the upper end inner wall of corresponding groove 1111, phase
Than 232 collision the first frame 111 generation of back-off during the first keycap 21 in the prior art, can be effectively prevented and resetted
Noise, and then the collision between keycap and frame can be efficiently reduced, reduce the operation noise of keyboard.
In the present embodiment, the spacing between the upper end inner wall of the corresponding groove 1111 in 232 upper surfaces of back-off is big always
It in or equal to 0.4-0.8mm, not only can guarantee that all kinds of performances of keyboard were more excellent, but also back-off 232 and frame can be better protected from
Between collision generate noise.
In the present embodiment, 21 bottom surface of the first keycap is downwardly extending there are two the limit plate 24 being oppositely arranged, and two are blocked
It hooks 23 to be located between two limit plates, 24 length direction both ends, the first corresponding frame of the length of two limit plates 24
111 inner wall is adapted.The effect of limit plate 24 is, efficiently reduces the first keycap 21 during pressing and reset
It shakes, reduces the collision between the first keycap 21 and the first frame 111, and then operation noise can be efficiently reduced.Back-off 232
Corresponding 1111 inner wall of groove keeps a fixed spacing, and the setting of back-off 232 and 1111 inner wall spacing of groove is further effective
Ground reduces the collision with the first frame 111, reduces operation noise.
In the present embodiment, as shown in Figures 2 and 3, two limit plates 24 all have the concave part 241 convexed to form in opposite directions,
First frame 111 inner wall corresponding with two limit plates 24 is equipped with lug boss 1112 compatible with concave part 241.Groove
The cooperation in portion 241 and lug boss 1112 further limits the mobile space of the first keycap 21, and then efficiently reduces
Shaking of one keycap 21 during pressing and reset reduces the collision between the first keycap 21 and the first frame 111, in turn
Operation noise can be efficiently reduced.Preferably, the cross section of concave part 241 is trapezoidal, effectively increase the first keycap 21 with
The contact area of first frame 111, and then preferably the first keycap 21 is limited.
In the present embodiment, as shown in Figure 1, Figure 2 and Figure 4, this mute keyboard further includes the second press-key structure 4 and is located at pedestal
1 the second placed cavity 12.Second press-key structure 4 includes the second keycap 41, the second pressing down section 42 for being located at 41 bottom surface of the second keycap
Be located at 42 bottom surface of the second pressing down section and flexible trigger member 3.Second placed cavity 12 has the second frame 121, the second frame
The inner wall of frame 121 is set there are two groove 1111.Second keycap, 41 bottom surface is downwardly extending there are two the hook 23 being oppositely arranged,
Each hook 23 includes the strip 231 for being connected to the second keycap 41 and the back-off 232 set on strip 231, and back-off 232 is sticked in it
It can slide in corresponding groove 1111 and along corresponding groove 1111, be buckled to the upper of the corresponding groove 1111 in 232 upper surfaces
A fixed spacing is remained between the inner wall of end.Wherein, the size of the second press-key structure 4 is bigger than the size of the first press-key structure 2, such as
The second press-key structure of fruit 4 only leans on the elastic force of trigger member 3 made of rubber after being pressed be to be insufficient to allow the second press-key structure 4 quickly
It resets, therefore, the second placed cavity 12 is equipped with the elastic support 43 for resetting the second keycap 41, passes through the elastic force of elastic support 43
It is 4 Rapid reset of the second press-key structure.Specifically, the bottom surface of the second keycap 41 is set there are two briquetting 44, the two briquettings 44 divide
Not Di Jie elastic support 43 both ends.The bottom surface both ends of second keycap 41 are respectively equipped with guide post 45, the bottom surface of the second placed cavity 12
There are two the guide holes 122 slided up and down for the two guide posts 45 for tool.When the second keycap 41 is pressed, two guide posts 45 are along two
122 slide downward of guide hole keeps the whole steady of the second press-key structure 4, and the both ends of elastic support 43 are pressed by two respectively at this time
Block 44 pushes and is in elastic stage；When the second keycap 41 is not pressurized, the both ends of elastic support 43 will be in elasticity
Two briquettings 44 are lifted upwards under state, so that 4 Rapid reset of the second press-key structure.Second keycap 41 also is provided with as above-mentioned
The limit plate 24 and concave part 241 of first keycap, 21 bottom surface are set, and served identical.
In the present embodiment, as shown in figure 3, trigger member 3 includes neck 31 and the bowl-shaped holder 32 for being connected to the neck 31, the
One pressing down section 22 and the second pressing down section 42 are equipped with limited post 221, and limited post 221 is inserted into the neck 31 of trigger member 3.Limited post
221 limits reduce trigger member 3 by the shaking in compression and reseting procedure, guarantee the reliability used for a long time.Trigger member 3
Compression travel is 3mm, and the compression travel of existing most of trigger member 3 only has 2.25mm, and the compression travel for increasing trigger member 3 can
To effectively improve the comfort level that user uses keyboard.
In the present embodiment, as shown in Figure 1, this mute keyboard further includes bottom plate 5 and circuit board 6, circuit board 6 is located at bottom plate 5
Between pedestal 1.It, can be by 22/ second pressing down section of the first pressing down section when downward the first 21/ second keycap 41 of keycap of force pressing
42 move down, thus force and trigger member 3 down, and circuit board 6 is connected.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
As long as all by the protection of Patent Law in the scope of the claims of the utility model.
