For more stable prying, the linkage part is perpendicular to the prying part. The tilting portion 602 is of a V-shaped structure, one end of the tilting portion 602, which is bent, is a long arm end 602a, the other end of the tilting portion 602, which is bent, is a short arm end 602b, the length of the long arm end 602a is greater than that of the short arm end 602b, the long arm end 602a is connected with the transverse connecting portion 603, and the short arm end 602b is connected with the linkage 7. After the keycap 2 is pressed down at any position (for example, one of four corners is pressed), the long arm end 602a of the pressed balance seesaw rod 6 moves downward and then the seesaw short arm end 602b moves upward, the short arm end 602b drives the short arm end 602b of the adjacent balance seesaw rod 602 to also move upward through the linkage 7, meanwhile, the short arm end 602b of the adjacent balance seesaw rod 6 tilts the long arm end 602a to move downward, and the linkage mechanism 5 enables the keycap 2 to be stably stressed without the occurrence of the tilting edge and can move downward in an integral horizontal manner.
In order to obtain a stable switching signal when being pressed, the electrical element 9 includes an infrared emitting end 901 and a receiving end 902, an optical path can be formed between the infrared emitting end 901 and the receiving end 902, and the optical path can be turned on or off when the trigger 3 descends, so as to output the switching signal. The electric element 9 comprises a Hall element, a magnet is installed on the trigger piece, and when the trigger piece descends to be close to the Hall element, the Hall element can sense the change of magnetic flux and further output a switching signal.
The limiting groove 802 is perpendicular to the key base 1, the minimum width of the limiting groove 802 is the same as the diameter of the end of the linkage part 601, and the end of the linkage part 601 can slide vertically along the limiting groove 802; the spacing between the limit salient points 801 and the key base 1 is larger than the maximum diameter of the tilting part 602.
The elastic reset piece 4 can be a spring, a torsional spring, an elastic sheet, a snap piece, a silica gel cap and other structures. When the elastic reset piece 4 is of a metal elastic sheet structure, the key base 1 is provided with an elastic sheet base 10, and the elastic reset piece 4 can be fixedly arranged on the elastic base 10; the trigger piece 3 and the elastic reset piece 4 are arranged between the balance tilted rods 6.
As shown in fig. 9, the electrical element 9 may be a membrane switch, the elastic reset member 4 is a silicone cap, and the trigger member 3 is a protrusion in the silicone cap. When the switch is pressed down, the silica gel cap is compressed downwards, and the bulge in the silica gel cap is contacted with the membrane switch to further output a switch signal. Or the dome sheet and the membrane switch are combined to output a switch signal.
Example one
As shown in fig. 1 and 5, the linkage 7 is an integrally injection-molded structure, the linkage 7 is composed of linkage blocks 701 and flexible belts 702, the linkage blocks 701 are injection-molded on the linkage part 601, and the adjacent linkage blocks 701 are connected together by the flexible belts 702.
According to the key cap of button optional position, the short armed end upward movement is waved in the long armed end downstream, and then lets linkage portion upward movement, and this linkage portion makes adjacent linkage portion rise together (the flexbile band can change folding angle at the in-process that rises) through the flexbile band, and then drives long armed end downstream through adjacent portion of waveing, and the key cap whole body can downstream together, can not stick up the limit, presses down sensitivity height. Because the long arm end and the short arm end are in a tilting relationship, the linkage part is limited by the limiting groove and can only slide up and down, and along with the rising of the linkage part, the supporting position (the contact position of the lower surface of the tilting part and the surface of the key seat) of the balance tilting rod moves towards the direction of the limiting groove (the tilting part does not rotate around the shaft, and the supporting point of the tilting part is not unique). Meanwhile, the transverse connection part of the balance warping rod on the key cap buckle is unfolded and slides towards two sides. Because the spacing groove is vertical structure, the interval between the linkage piece keeps unchangeable, and the flexible band warp lessly, is difficult for being dragged the damage.
Example two
As shown in fig. 2, 4 and 5, the linkage member 7 is composed of a linkage convex tooth 703 and a linkage concave groove 704 matched with the linkage convex tooth 703, the linkage convex tooth 703 is installed on one of the linkage parts 601, the linkage concave groove 704 is installed on the other linkage part 601 adjacent to the linkage convex tooth, and the linkage convex tooth 701 is movably embedded in the linkage concave groove 704;
after pressing key cap one side corner of button, the short armed end upward movement is waved in the long armed end downstream, and then lets linkage portion upward movement, and this linkage portion makes adjacent linkage portion rise together through linkage dogtooth tilting linkage recess, and then drives long armed end downstream through adjacent portion of waveing, and the key cap whole body can downstream together, can not stick up the limit, presses down the sensitivity height. Because the long arm end and the short arm end are in a tilting relationship, the linkage part is limited by the limiting groove and can only slide up and down, and along with the rising of the linkage part, the supporting position (the contact position of the lower surface of the tilting part and the surface of the key seat) of the balance tilting rod moves towards the direction of the limiting groove (the tilting part does not rotate around the shaft, and the supporting point of the tilting part is not unique). Meanwhile, the transverse connection part of the balance warping rod on the key cap buckle is unfolded and slides towards two sides, and the key cap and the key seat are sealed tightly and cannot move horizontally when being pressed. Because the limiting grooves are of a vertical structure, the distance between the linkage convex teeth and the linkage grooves is kept unchanged, the stability is better, and the linkage convex teeth can be stably meshed and linked with the linkage grooves.
According to the ultrathin key, the balance warping rod is matched with the linkage piece, so that the phenomenon of edge warping can be effectively reduced when the key cap is pressed at any position while an ultrathin structure is realized, the whole key cap can be guaranteed to be stably stressed and descended, and the triggering sensitivity is high; adopt linkage portion, the balance stick up the pole that stick up portion and cross connection portion are constituteed, press the in-process, the balance stick up the realization stick up that the pole can be stable and move the linkage, the spacing groove that cooperates the perpendicular setting simultaneously, the link is difficult wearing and tearing, and link linkage stability is better.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and any minor modifications, equivalent replacements and improvements made to the above embodiment according to the technical spirit of the present invention should be included in the protection scope of the technical solution of the present invention.
