Specifically, the jacking block 111 is used for abutting against the keycap 4 and jacking up the keycap 4; or the jacking pieces 111 are used to interfere with the first bracket 31 and jack up the first bracket 31.
In practical application, the key starting plate 11 and the moving plate 13 move in the same direction, the moving plate 13 can pull the second support 32 to rotate upwards or downwards, the rotating second support 32 can drive the key cap 4 to lift, meanwhile, the lifting of the key cap 4 drives the first support 31 to rotate, and the key cap 4 can be stably lifted under the support of the first support 31; meanwhile, when the keycap 4 is pressed, the feedback feeling of the key can be improved and the comfort level of the key of the user can be improved under the movable support of the first support 31 and the second support 32. Therefore, when the key is used, the key lifting plate 11 and the moving plate 13 are driven to move rightwards, the moving key lifting plate 11 drives the jacking block 111 to move, the jacking block 111 is enabled to be in contact with the keycap 4, and the keycap 4 is jacked; or, the moving key-lifting plate 11 drives the key-lifting block 111 to move and make the key-lifting block 111 contact with the first support 31, so as to lift the first support 31, and thus the key cap 4 is lifted; after the keycap 4 is jacked up, the moving plate 13 drives the second support 32 to rotate upwards, and the rotating second support 32 drives the keycap 4 and the first support 31 to synchronously lift up, so that the keycap 4 is used by a user; when the key is not used, the moving plate 13 is driven to move leftwards, the moving plate 13 drives the second support 32 to rotate downwards, the rotating second support 32 drives the keycap 4 to descend until the keycap 4 descends to the folded state, and the thickness of the keyboard is reduced, so that the keyboard becomes thinner. As shown in fig. 10, when the key cap 4 is in the folded state, the first support 31 and the second support 32 are in the same horizontal straight line, thereby forming a self-locking force on the key cap 4, in this state, if the moving plate 13 is merely pulled, the second support 32 cannot be pulled to rise, therefore, in this embodiment, the key plate 11 must be used to drive the lifting block 111 to move, so that the lifting block 111 generates an upward pushing force on the key cap 4, the lifting block 111 lifts the key cap 4, and the lifting of the key cap 4 drives the second support 32 to rotate upward; or, as shown in fig. 13, the jacking block 111 is driven to move, so that the jacking block 111 collides with the first bracket 31, and further generates an upward thrust on the first bracket 31, so as to jack up the first bracket 31; through the two manners, the second support 32 and the first support 31 are not on the same horizontal straight line, so that the moving plate 13 pulls the second support 32 to continue moving and the second support 32 rotates upwards until the keycap 4 is lifted to the use state. The embodiment of the utility model discloses a mode through realizing 4 lifts of key cap is so that the keyboard attenuation, and then makes the button need not to shorten the stroke of button when using to when making the button keep original comfort level and feedback to feel, can be with the attenuation of realizing the keyboard again, and reduced the fault rate of button.
Preferably, the side of the key cap 4 close to the jacking block 111 is provided with an inclined surface 41, and the top of the jacking block 111 is provided with a slope surface 112 matched with the inclined surface 41 of the key cap 4. Due to the structural design of the inclined sliding, the keycap 4 can be easily jacked up by the jacking block 111 in a labor-saving manner. Similarly, the jacking block 111 may also abut against the first support 31 through the slope surface 112 to jack up the first support 31, so as to jack up the keycap 4.
Preferably, as shown in fig. 2, the first bracket 31 and the second bracket 32 are both U-shaped, and the first bracket 31 and the second bracket 32 are arranged to intersect with each other. The open end of the first support 31 is hinged with the fixed plate 12, and the top cross rod of the first support 31 is rotatably connected with the keycap 4 through the clamping buckle 43; the open end of the second bracket 32 is hinged with the moving plate 13, and the top cross bar of the second bracket 32 is rotatably connected with the keycap 4 through a buckle.
In the technical scheme, the movable support 3 further comprises a reset elastic member 33, one end of the reset elastic member 33 is connected with one end of the first support 31 close to the keycap 4, and the other end of the reset elastic member 33 is connected with the keycap 4; or both ends of the return elastic member 33 are connected to the first bracket 31 and the second bracket 32, respectively. Preferably, the return elastic member 33 may be an existing spring; in this embodiment, one end of the elastic restoring member 33 is connected to one end of the key cap 4 via the hook 42, and the other end of the elastic restoring member 33 is connected to the first support 31.
