Touch, so as to reach the purpose of input through keyboard.Elastic component is additionally provided between key cap base and key cap cover, with reset response, energy
The key cap cover being pressed enough is allowed to be automatically moved up, to restore to the original state.
In sum, the technical program uses columned key cap cover and key hole, and on key cap cover and key hole
The boss and groove of mutual cooperation are respectively equipped with, can be allowed inside keyboard body inside and key cap cover all the time in approximate close
The state of envelope, efficiently avoid the entrance of dust.In addition, during key cap cover is moved up and down, can only be subject to side vertically
To frictional force, without the pressure by another its side wall turnover, therefore, it is possible to avoid the junction of key cap cover side wall and top surface
It is damaged.
The following is the preferred scheme of such scheme：
Preferred scheme one：Based on base case, the groove and boss are two, and the distance between two grooves are equal to
The distance between two boss.During key cap cover is moved up and down, at least one boss is in the grooves such that it is able to
The state of near-hermetic is in inside guarantee keyboard body inside and key cap cover all the time, entering for dust is efficiently avoid
Enter.
Preferred scheme two：Based on preferred scheme one, the elastic component is back-moving spring, and back-moving spring is uniformly distributed.Reset
Spring to be uniformly distributed the active force that key cap cover can be allowed to be subject to more balanced, it is to avoid key cap cover inclines because of unbalance stress
Tiltedly, the use of keyboard is influenceed.
Preferred scheme three：Based on preferred scheme two, the back-moving spring has 4.By four equally distributed reset bullets
Spring is to ensure that on key cap cover that the active force that the position on formed symmetrical is subject to is identical, it is to avoid key cap cover run-off the straight.
Preferred scheme four：Based on base case, the key cap cover is formed in one, and makes boss whole with key cap cover formation one
Body, with boss and key cap cover separate machined compared with assembling is carried out, boss is even closer with the connection of key cap cover, can avoid convex
Platform departs from from key cap cover.
Preferred scheme five：Based on preferred scheme four, the distance between the contact block and printed circuit are equal to back-moving spring
Largest deformation amount so that after pressing key cap cover completely, contact block is just contacted with printed circuit, completes the input of information.Work as contact block
During with the distance between printed circuit more than back-moving spring maximum compressibility, key cap cover is pressed completely can cause contact block intense impact
Printed circuit, or even cause the breakage of printed circuit.
Preferred scheme six：Based on preferred scheme five, the contact block is cylindrical, and contact block is coaxially disposed with key cap cover,
So that contact block to key cap cover edge apart from all same, can be in the case where key cap cover edge be under pressure still to moving down
It is dynamic, make the sensitivity of keyboard higher.
