Detailed description of the invention
By feature of the present utility model, technological means and the specific purposes reached, function can be further appreciated that, resolve
Advantage of the present utility model and spirit, entered detailed description of the present utility model with detailed description of the invention by below in conjunction with accompanying drawing
The understanding of one step.
See Fig. 1 to Fig. 3, it is provided that the schematic diagram of the vocal structure 10 of a kind of keyboard switch.
A kind of vocal structure 10 of keyboard switch, including: pedestal 20, spring 30, lead core 40 and location bar 50.
This pedestal 20 is provided with coupling and leads the accepting groove 21 of core 40, and the bottom of this accepting groove 21 is provided with the peace of coupling location bar 50
Tankage.It addition, be provided with the cylinder of projection at the bottom center of accepting groove 21.
This spring 30 is spirality metal spring 30, on the cylinder of the bottom that its one end is connected to accepting groove 21, and the other end
It is connected to the one end leading core 40 towards pedestal 20.
This side leading core 40 is provided with loose slot 41 and the guide pad 42 being separately positioned in loose slot 41 and impact block
43.Guide pad 42 constitutes first passage 44(as in figure 2 it is shown, first passage 44 is positioned at guide pad with a sidewall of loose slot 41
Left side).Guide pad 42 constitutes second channel 45(as in figure 2 it is shown, second channel 45 is positioned at guiding with another sidewall of loose slot 41
The right side of block 42).The bottom of second channel 45 connects with the bottom of first passage 44.The top of second channel 45 and first passage
The top connection of 44.Impact block 43 is positioned at the top of first passage 44.In the present embodiment, guide pad 42 generally square block sets
Put.On guide pad 42, the side of adjacent first passage 44 is provided with the first arcwall face 46.Adjacent second channel 45 on guide pad 42
Side is provided with the second arcwall face 47.The bottom of guide pad 42 is provided with from first passage 44 towards second channel 45 and gradually toward updip
The first oblique inclined-plane 48.The top of guide pad 42 be provided with from first passage 44 towards second channel 45 and the most up tilt
Two inclined-planes 49.First passage 44 is curved channel.
This location bar 50 is the elastic metallic bar of L-shaped.One end of location bar 50 is fixed in above-mentioned mounting groove, and the other end sets
There is the bearded needle 51 of the bottom being connected to first passage 44.
Principle of sound is following, and (structure shown in figure is that the vocal structure 10 of keyboard switch of the present utility model is opened with keyboard
Three kinds of working state schematic representations after lid 60 combination closed):
As shown in Figure 4, leading core 40 and be positioned at initial position, bearded needle 51 is connected to the bottom of first passage 44.
Moving down under external force as it is shown in figure 5, lead core 40, location bar 50 produces to the right shape in the compressing of guide pad 42
Becoming, bearded needle 51 enters the bottom of first passage 44 and is trapped in second channel 45 and it is relative from the bottom of first passage 44
The gradually upper shifting in the position of guide pad 42.
As shown in Figure 6, leading core 40 and continue to move down, bearded needle 51 reaches the top of second channel 45 and departs from guide pad 42,
Location bar 50 is under the effect of deformation restoring force to the left, and bearded needle 51 moves to first passage 44 from the top of second channel 45
Top also impacts impact block 43 and sends the sound.
The vocal structure 10 of above-mentioned keyboard switch, when applying external force is in time leading core 40, leads 40 times pressures of core and spring 30 quilt
Compression, in guide pad 42 folding process, its edge forces location bar 50 swing generation deformation and make bearded needle 51 enter second channel
45；Pressing when leading under core 40 continues, bearded needle 51 arrives the top of second channel 45 and departs from guide pad 42, and bearded needle 51 is at location bar 50
The effect lower impact impact block 43 of deformation power send the sound and be transferred to the top of first passage 44.Core is led when removing to act on
The external force of 40, spring 30 leads the active force that core 40 upwards resets, and leads bearded needle 51 during moving on core 40 and enters first and lead to
Road 44, until returning back to initial position, completes a switch motion sounding.By above-mentioned design so that keyboard switch is pressed
Time produce sound, use feel good and improve user's comfort.
Each technical characteristic of above example can combine arbitrarily, for making description succinct, not to above-described embodiment
In all possible combination of each technical characteristic be all described, but, as long as there is not lance in the combination of these technical characteristics
Shield, is all considered to be the scope that this specification is recorded.
Above example only have expressed that of the present utility model preferred embodiment it describes more concrete and in detail, but
Therefore the restriction to utility model patent scope can not be interpreted as.It should be pointed out that, for the ordinary skill of this area
For personnel, without departing from the concept of the premise utility, it is also possible to make some deformation and improvement, these broadly fall into this
The protection domain of utility model.Therefore, the protection domain of this utility model patent should be as the criterion with claims.
