Description

The bridge formation of button and machine plate composite set

The utility model relates to by strong structure.

The keyboard structural group of existing Computer key is by organic plates, circuit board, flexible member, bridge formation and keycap are constituted in regular turn from bottom to top by plate top surface, this machine plate one side is provided with the articulated section of symmetry, side also is arranged with embedded and slide part in addition, the keycap bottom surface is respectively equipped with the axle pivot portion and the guide sliding part of symmetry, and building bridge is formed by two framework pivot joint group structures; Wherein stretch in a framework one side and be provided with two pivot posts, can be nested in the machine plate axle pivot portion, other side then is provided with roller and can slides along the guide sliding part of keycap, and another framework one side is provided with cylinder and can rotates in the axle pivot portion of keycap, opposite side is stretched and is provided with traveller and can slides in machine plate embedded and slide part, flexible member is sheathed in the accommodation space of two frameworks, and circuit board then places between flexible member and the machine plate, promptly forms a keyboard structure according to the above; Yet because this is for the machine plate embedded and slide part cover edge of bridge formation framework traveller setting-in, it is the vertical slidably one-sided open content space of establishing that forms along the traveller glide direction, when the traveller setting-in of this machine plate embedded and slide part and bridge formation framework, because this is between the embedded and slide part of vertical design and traveller suitable guide design is not arranged, cause the interfere in ends before embedding to hinder easily between the two, generally all need utilize the bridge formation framework after traveller suffers oppression certain degree, produce the tortuous distortion of elasticity and sliding imbedding into sliding space, make bridge formation and the generation of machine plate install uncertain easily, even owing to produce traveller or frame deformation because of contention effect is improper, situation about can't recover, have a strong impact on the smoothness of processing operation, and invisible increases fraction defective.

The purpose of this utility model provides the bridge formation and the machine plate composite set of the more smooth and easy button that improves the quality of a kind of assembling.

The purpose of this utility model is achieved in that the bridge formation and the machine plate composite set of button, it comprises keycap, flexible member, machine plate and bridge formation, establish the framework that an X type staggered form is built bridge between a machine plate and the keycap, and the frame end of at least wherein building bridge is provided with traveller, and with the machine plate on the embedded and slide part sliding gomphosis mutually of correspondence position, it is characterized in that: this embedded and slide part is provided with a cover edge, the below forms the slippage slot of the sliding embedding of a traveller, and the cover edge end is provided with a guiding setting that direction forms in slippage slot.

Above-mentioned design, mat be in the terminal set this guiding setting of embedded and slide part cover edge, and it is suitable with the chimeric cunning of framework to make it have the guiding of a mitigation traveller, and it is smooth and easy to have reached assembling, the effect of quality raising.

Be described further again below by accompanying drawing, embodiment.

As shown in Figure 1, 2: the utility model comprises keycap 1, flexible member 2, machine plate 3 and builds bridge 4, establish the

framework

41,42 of X type staggered form bridge formation 4 between a machine plate 3 and the keycap 1, and 4 one frame end of at least wherein building bridge are provided with traveller 46, and with machine plate 3 on embedded and slide part 32 sliding gomphosis mutually of correspondence position, it is characterized in that: this embedded and slide part 32 is provided with a cover edge 33, the below forms the slippage slot 331 of a traveller 46 sliding embeddings, and cover edge 33 ends are provided with a guiding that direction forms in slippage slot 331 and are provided with 35.Wherein, guiding is provided with 35 leading edges that become to cut sth. askew from the stage casing of cover edge 33 outer rim 39 in slippage slot 331.Wherein, guiding is provided with 35 leading edges that become arc to cut from the stage casing of cover edge 33 outer rim 39 in slippage slot 331.Wherein, cover edge 33 upper limbs 38 are provided with the lead angle edge.Wherein, embedded and slide part 32 corresponding rollers 44 or

framework

41,42 be in the sliding outer inclined to one side position that embeds embedded and slide part 32, machine plate 3 cut be provided with the portion 37 of dodging, for the interference and the obstruction of the operation room of dodging.

Shown in Fig. 1-5: wherein, keycap 1, flexible member 2 etc. are all prior art, be respectively equipped with articulated section 31 and embedded and slide part 32 on the machine plate 3, one end of 31 unit of being located at key areas, articulated section, and forms by guiding flange 311 and

hook limit edge
