Detailed Description
The invention will be further described with reference to the following examples.
As can be seen from fig. 1 to 7; the key switch with the scissors foot structure comprises a keycap 1, a base 2, a scissors foot structure 3 arranged between the keycap 1 and the base 2, a circuit board 4 arranged in the base 2 and a switch structure for triggering the key switch; the switch structure comprises a first contact 41, a second contact 42, a metal elastic sheet 5 and a switch shaft 6 for pressing the metal elastic sheet 5 to electrically connect the first contact 41 and the second contact 42; the first contact 41 and the second contact 42 are arranged on the circuit board 4; the first contact 41 includes a first latch 71 electrically connected to the first contact 41; one end of the metal elastic sheet 5 is fixed on the first clamping block 71 and is electrically connected with the first clamping block 71; one end of the switch shaft 6 is abutted against the metal spring plate 5; the device also comprises a reset structure for resetting the metal spring plate 5; when the key cap 1 presses the metal spring piece 5 through the switch shaft 6, the other end of the metal spring piece 5 abuts against the second contact 42 and is electrically connected with the second contact 42; when the metal spring plate 5 is reset, the other end of the metal spring plate 5 is abutted against the inner wall of the base 2.
Specifically, in the keyboard key according to the present embodiment, under normal conditions, as shown in fig. 4, the metal spring 5 is abutted against the upper wall of the base 2 at the right end, and at this time, the metal spring 5 is separated from the second contact 42, so that the first contact 41 is disconnected from the second contact 42;
When the trigger switch is needed, the key cap 1 is pressed down, so that the switch shaft 6 presses the metal elastic sheet 5 downwards until the rightmost end of the metal elastic sheet 5 abuts against the second contact 42, as shown in fig. 3, at this time, the first contact 41 and the second contact 42 are electrically conducted, and the first sound is generated due to collision between the metal elastic sheet 5 and the second contact 42;
When needs reset, loosen key cap 1, reset structure makes metal shrapnel 5's right-most end reset to thereby metal shrapnel 5 collides with the upper wall of base 2 and sends the secondary and rattles, realizes mechanical keyboard's sound production function, realizes mechanical feel through twice collision simultaneously. In addition, the embodiment adopts fewer structures to realize mechanical handfeel, so that the whole key switch is thinner and is suitable for a portable computer.
As described in fig. 3 and 4; the key switch with a scissor structure in this embodiment, the reset structure includes a second clamping block 72 disposed on the first contact 41 and an elastic hook 51 disposed on the metal elastic sheet 5; the second clamping block 72 is clamped with the elastic clamping hook 51.
When the switch shaft 6 presses the metal elastic sheet 5 to move downwards, the distance between the elastic clamping hook 51 and the clamping block is reduced, so that the elastic clamping hook 51 deforms to store force, and when the key cap 1 is loosened, the metal elastic sheet 5 is reset due to the reset action of the elastic clamping hook 51.
In the key switch with a scissor structure of this embodiment, the elastic hook 51 and the metal spring 5 are integrally formed. The arrangement is convenient for manufacturing the metal spring piece 5.
As shown in fig. 3 and 4; in the key switch with a scissor structure of this embodiment, the section of the elastic hook 51 is arc-shaped; the circuit board 4 is provided with an arc-shaped groove 43 for accommodating the elastic hook 51. The deformation space of the elastic hook 51 can be increased by making the cross section of the elastic hook 51 arc-shaped and the arc-shaped groove 43.
As shown in fig. 3 and 4; in the key switch with a scissor structure in this embodiment, the metal spring 5 extends toward the switch shaft 6 to form an elastic contact 52; the elastic contact piece 52 abuts against one end of the switch shaft 6. Through setting up the stroke that the elastic contact piece 52 can increase metal shrapnel 5 and descend, when the switch shaft 6 oppresses metal shrapnel 5 and moves down, at first the switch shaft 6 oppresses the elastic contact piece 52 and descends earlier, and when elastic contact piece 52 and metal shrapnel 5 were in same horizontal line, the elastic contact piece 52 of continuing to push down can make metal shrapnel 5 whereabouts thereby with second fixture block 72 support, through increasing the stroke that metal shrapnel 5 descends in order to improve the sense of touch.
In the key switch with a scissor structure of this embodiment, the elastic contact 52 and the metal elastic sheet 5 are integrally formed. The arrangement is convenient for manufacturing the metal spring piece 5.
As shown in fig. 5 to 7; the key switch with a scissor structure according to the present embodiment, the scissor structure 3 includes an outer frame 81 and an inner frame 82 rotatably installed in the outer frame 81; two ends of the outer frame 81 are respectively pivoted with the base 2 and the keycap 1; two ends of the inner frame 82 are respectively pivoted with the base 2 and the keycap 1;
the outer frame 81 is provided with a shaft hole 811; the inner frame 82 is provided with a pivot 821 fitted to the shaft hole 811; the upper surface of the outer frame 81 is provided with a guide groove 83 communicating with the shaft hole 811; the guide groove 83 is provided with an elastic protrusion 831 for making the width of the guide groove 83 smaller than the diameter of the shaft hole 811 at the connection with the shaft hole 811.
Because the conventional scissor leg structure 3 must be manually checked to be assembled correspondingly in the left-right direction and the backward-forward direction of the scissor leg during assembly, a great deal of labor cost is wasted, and the accuracy is not high, defective products are easily produced, and automation cannot be realized, in this embodiment, when the inner frame 82 is installed in the outer frame 81, only the pivot 821 of the inner frame 82 needs to be aligned with the opening of the guide groove 83 on the surface of the outer frame 81, after the pivot 821 is inserted into the guide groove 83, the pivot 821 slides along the guide groove 83 until the pivot 821 reaches the connection position of the guide groove 83 and the shaft hole 811, and because the width of the guide groove 83 is smaller than the diameter of the shaft hole 811, an external force needs to be applied to the pivot 821, and then the elastic bump 831 is pressed to deform the elastic bump 831, so that the pivot 821 is installed in the shaft hole 811, and the assembly of the scissor leg structure 3 is completed. By the above structure, the installation process of the outer frame 81 and the inner frame 82 is more convenient and simple.
As shown in fig. 7; in the key switch with a scissor structure according to the embodiment, the guiding groove 83 is a chute formed in the outer frame 81 along the length direction. By providing the guide groove 83 as a chute, the assembly of the outer frame 81 and the inner frame 82 is facilitated.
