Description

Novel scissor type key structure

Technical Field

The utility model relates to a technical field of keyboard button indicates a novel cut fork button structure especially.

Background

Most of the existing keyboard keys utilize elastic materials such as silica gel and soft rubber as elastic pieces to be conducted with a conductive film to complete instruction input, but the elastic materials are slower in elastic recovery after being stressed compared with springs, so that the situation that the keys are reset too fast and the contact time of the elastic pieces and the conductive film is too short to cause disconnection can occur after an operator (particularly an electronic contestant) quickly strikes the keys.

In order to solve the problem, the utility model provides a remove steady, touch the sensitive novel fork button structure of cutting.

In order to achieve the above object, the utility model adopts the following technical scheme: the utility model provides a novel cut fork button structure, includes the key cap, cuts the fork connecting piece, switches on and the base plate, the key cap goes up and down to move on the base plate through cutting fork connecting piece and first spring, be equipped with the conductive film on the base plate, switch on and pass through the second spring coupling at the key cap.

Preferably, the substrate is provided with a first connecting block and a second connecting block, the first connecting block is provided with a first clamping groove, and the second connecting block is provided with a second sliding groove.

Preferably, the inside lateral wall of key cap is equipped with first spout and second draw-in groove.

Preferably, cut fork connecting piece and include that first cut foot and second cut the foot, first cut foot and second cut the rotatable cross connection of foot, first one end of cutting the foot is rotatable to be established on the base plate, and the other end is portable to be established in the key cap, the second is cut the one end of foot and is rotatable to be established in the key cap, and the other end is portable to be established on the base plate.

The beneficial effects of the utility model reside in that: the utility model discloses simple structure utilizes and cuts the fork connecting piece for bearing structure, makes the lift of key cap remove more steadily, adopts the spring to add the structure of switch-on piece, when the key cap resets and shifts up, switch-on piece still keep with the conducting film butt a period, reduces the condition emergence that touches absolutely.

Detailed Description

Please refer to fig. 1-6, the present invention relates to a novel scissor-type key structure, which comprises a key cap 1, a scissor-type connecting member 2, a conducting member 4 and a substrate 5, wherein the key cap 1 moves on the substrate 5 through the scissor-type connecting member 2, the substrate 5 is provided with a conductive film, the key cap 1 is connected to the substrate 5 through a first spring 6, and the conducting member 4 is connected to the key cap 1 through a second spring 7.

Preferably, be equipped with first connecting block 8 and second connecting block 9 on the base plate 5, two first connecting blocks 8 are the quadrangle setting with two second connecting blocks 9, be equipped with first draw-in groove 81 on the first connecting block 8, be equipped with second spout 91 on the second connecting block 9.

Preferably, the inside lateral wall of key cap 1 is equipped with first spout 11 and second draw-in groove 12, the middle part of key cap 1 is equipped with a hollow spliced pole 13, the bottom of spliced pole 13 is equipped with the trip, it is spacing removal in spliced pole 13 that the piece 4 that switches on passes through second spring 7.

Preferably, cut fork connecting piece 2 and include that first scissor 21 and second scissor 22, first scissor 21 and second scissor 22 rotatable cross connection, first scissor 21's one end is rotatable to be established in first draw-in groove 81 of two first connecting blocks 8, and the other end is portable to be established in second spout 91 of second connecting block 9, second scissor 22's one end is rotatable to be established in two second draw-in grooves 12 of key cap 1, and the other end is portable to be established in first spout 11 of key cap 1, and when key cap 1 moved down, first scissor 21 and second scissor 22 rotated with key cap 1 and connecting block cooperation respectively, made key cap 1 stably go up and down.

The working principle is as follows: the exogenic action is on key cap 1, and key cap 1 steadily descends under the support of cutting fork formula connecting piece 2, and first spring 6 is in compression state, contradicts on the conductive film when switching on 4, and second spring 7 is in compression state, the utility model discloses and the circuit board circular telegram in the keyboard, after removing the external force, second spring 7 resilience that resets, key cap 1 steadily shifts up under the support of cutting fork formula connecting piece 2, switches on 4 then because of the butt that the elastic force effect that receives second spring 7 kept with the conductive film earlier, switches on 4 along with key cap 1 shifts up after the second spring 7 resets, just separates with the conductive film.

The traditional key structure adopts elastic pieces such as soft rubber and silica gel to realize conduction with a conductive film by utilizing self elastic deformation, and after a user quickly strikes a key, due to the fact that the elastic deformation of the elastic pieces has delay performance, the conduction time of the elastic pieces and the conductive film is too short, the phenomenon of breaking contact is easily caused; the utility model discloses compare with traditional button structure, remove stably, touch and press the sensitivity, when key cap 1 resets, switch-on 4 still keeps with conducting film butt a period, and the condition that reduces disconnected touch takes place.

The above embodiments are only for describing the preferred embodiments of the present invention, and are not intended to limit the scope of the present invention, and various modifications and improvements made by the technical solution of the present invention by those skilled in the art are all within the scope of the present invention as defined by the claims.
