Examples
Referring to fig. 1-3, the present embodiment provides an anti-key-jamming keyboard, including a panel 1, a keyboard plate 4, a key mat 3 and a plurality of key caps 2; the panel 1 is provided with a plurality of through holes 11 for mounting the keycaps 2; the keyboard plate 4 is positioned at the rear side of the panel 1 and is provided with a plurality of keys 5; the key pad 3 comprises a plate body 31 arranged between the panel 1 and the keyboard plate 4 and a plurality of elastic cushion blocks 32 arranged on the plate body 31, wherein each elastic cushion block 32 is arranged between the corresponding key cap 2 and the corresponding key 5 and used for supporting the key cap 2 and avoiding the key cap 2 from shaking.
As shown in fig. 4, the key 5 includes a body 51 fixed to the keyboard board 4, a button 52 protruding forward from the body 51, and a support ring 54 fitted over the body 51; when the key cap 2 is pressed, the button 52 moves backwards to trigger an instruction; the front end of the support ring 54 protrudes beyond the front side 2211 of the body 51 for supporting the rear side of the resilient pad 32.
As shown in fig. 2, 5 and 6, the elastic pad 32 includes a support body 321, an elastic body 322 and an elastic coupling ring 323; the support body 321 is connected with the plate body 31 and sleeved with the button 52, the outer side of the support body 321 is square, the inner side of the support body 321 is round, and the rear side of the support body 321 is abutted to the support ring 54; the elastic body 322 is arranged in front of the corresponding button 52, and the front end thereof is exposed forwards from the support body 321 and is abutted against the keycap 2; the elastic connection ring 323 connects the inner wall of the support body 321 and the outer circumference of the elastic body 322, so that the elastic body 322 has a tendency to return forward after being pressed.
As shown in fig. 3, the elastic coupling ring 323 has an L-shaped cross section, and includes a first extension 3231 extending forward from an inner wall of the support 321 and a second extension 3232 extending laterally from a front end of the first extension 3231 and connecting side edges of the elastic body 322. When the elastic body 322 is pressed, the elastic connecting ring 323 deforms and has weak elasticity, and the pressing hand feeling is not affected. The resilient pad 32 further includes a plurality of posts 324 protruding rearward from the rear end of the resilient body 322, and the rear end of the posts 324 abuts against the button 52. The plurality of convex columns 324 are circumferentially and equidistantly distributed on the rear end surface of the elastic body 322 to facilitate structural balance. The diameter of each convex column 324 is 0.8-1mm, the length is 1.2-1.8mm, the preferred number is 3-6, the total deformation elasticity of the convex columns 324 is controlled to be about 50gf, the total deformation elasticity is far greater than the gravity of the key cap 2 and the friction force of the elastic positioning sheet and the panel 1, the circular bead 24 of the key cap 2 is sufficiently pressed to be attached to the panel 1, the key cap 2 is prevented from shaking when the panel 1 is lightly shaken, the deformation elasticity is generally greater than 100gf when the key 5 is pressed, the deformation of the convex columns 324 is not enough to press the key 5, but enough pretightening force is provided to press the key cap 2, the maximum design gap is kept between the bottom surface of the main body of the key pad 3 and the top surface of the key 5, and the gap is the pressing stroke. Before the rear end of the elastic body 322 contacts the top surface of the key 5, the finger pressing force is equal to the total pre-tightening force of the small cylinder, when the bottom surface of the elastic body 322 contacts the top surface of the key 5, the finger pressing force is equal to the elastic force of the key 5, when the operation is completed, the finger pressing force is increased, the elastic body 322 deforms, the bottom surface of the keycap 2 contacts the top surface of the supporting body 321, the keycap 2 is prevented from continuing to advance, and the purpose of protecting the key 5 is achieved. When the finger pressing position deviates from the center of the keycap 2, the rear end edge of the keycap 2 is firstly contacted with the edge of the square support body 321, so that the keycap 2 is prevented from continuously deflecting, and the pressing operation is ensured to be completed.
Further, the key 5 further comprises a projection 53 projecting forward from the body 51, the projection 53 is located outside the button 52, and the front end surface of the projection is arc-shaped; the rear end of the support 321 is provided with a groove 3211 matching the projection 53.
As shown in fig. 3 and 7, the key cap 2 is inserted into the corresponding through hole 11. Each keycap 2 comprises a top wall 21, a shoulder 24, a side wall 22 connecting the edge of the top wall 21 and the shoulder 24, and a convex rib 25 formed by extending backwards from the back side of the top wall 21; the shoulder 24 is positioned between the panel 1 and the key pad 3, the front side of the shoulder abuts against the edge of the through hole, and the keycap is placed to fall off; the side wall 22 is in clearance fit with the through hole, a plurality of elastic positioning pieces 23 which extend backwards and are elastically abutted to the through hole 11 are arranged on the outer side of the side wall 22, a guide surface 231 which is abutted to the rear end of the corresponding through hole is arranged on the outer side of each elastic positioning piece 23, and the guide surface 231 inclines outwards gradually from front to back. In this embodiment, the guiding surface 231 is an inclined surface, and in other embodiments, the guiding surface 231 may be an arc surface. The elastic locating plate 23 has the tendency of swinging outwards, the weight of the key cap 2 is about 1.5g, the elastic force of the single elastic locating plate 23 is about 5-10gf, and the dislocation of the key cap 2 is corrected enough to keep the key cap in the middle of the through hole. In addition, can strengthen the through-hole through setting up elastic positioning piece 23, solve the problem that key cap 2 easily blocked in the current keyboard, and add elastic positioning piece 23 and hardly increase the preparation degree of difficulty of key cap 2. The rear end of the rib 25 abuts against the elastic body 322, and in the embodiment, the rib 25 is arranged into a plurality of concentric rings, which is beneficial to saving materials and reducing the weight of the keycap 2.
As shown in fig. 7, the front end of the sidewall 22 is provided with a plurality of notches 221 formed by recessing from the outside to the inside, each notch 221 has a front side 2211 and an inner side 2212 connected to the front side 2211, the front side 2211 is connected to the front end of the corresponding elastic positioning piece 23, and the inner side 2212 is spaced from the corresponding elastic positioning piece 23 to form a moving space of the elastic positioning piece 23. Because the outside of elastic locating piece 23 sets up guide surface 231, when pressing key cap 2, key cap 2 retreats, and elastic locating piece 23 outwards expands gradually, and the resistance between elastic locating piece 23 and the through-hole 11 diminishes gradually, solves the painful problem of feeling poor with pressing of finger. In this embodiment, the key cap 2 is rectangular, the side wall 22 thereof includes four wall portions that are connected in sequence, each wall portion all is equipped with the elastic locating piece 23, and a plurality of wall portions on each key cap 2 use the central line of key cap 2 as the benchmark and are central symmetry distribution to do benefit to structural balance. Of course, in other embodiments, the key cap 2 can be adjusted to be circular, triangular, etc. according to the actual situation.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
