Specific embodiment

Multiple embodiments that the utility model will be disclosed with schema below, as clearly stated, in many practices Details will be explained in the following description.It should be appreciated, however, that the details in these practices does not apply this with limitation practical new Type.That is, the details in these practices is non-essential in the utility model some embodiments.In addition, to simplify For the sake of schema, some existing usual structures and component will be painted it in a manner of simply illustrating in the drawings.

Please refer to Fig. 1.Fig. 1 is the perspective view for being painted the key device 100 of one embodiment of the utility model.Such as Fig. 1 institute Show, the key device 100 of present embodiment can be the external connection keyboard used for desktop computer, or comprising with keypad form For the computer system (for example, laptop or laptop computer) of input equipment, but it is not limited thereto.In other words, The concept of the key device 100 of the utility model can be applied to any electronic product using key device as input interface.

A to Fig. 2 D referring to figure 2..Fig. 2A is the front view for being painted the balancing pole 130 of one embodiment of the utility model.Figure 2B is the lower view that the balancing pole 130 being painted in Fig. 2A is connected with keycap 120.Fig. 2 C be the balancing pole 130 that is painted in Fig. 2A with The top view that bottom plate 110 is connected.Fig. 2 D is the sectional view of the key device 100 that is painted in Fig. 1 along line segment 2D-2D.Such as Fig. 1 to figure Shown in 2D, in present embodiment, key device 100 includes bottom plate 110, keycap 120, balancing pole 130 and reinforcing member 140.Key Cap 120 is set to 110 top of bottom plate.Balancing pole 130 is connected between bottom plate 110 and keycap 120.Reinforcing member 140 is connected to flat It weighs on bar 130.The quantity of balancing pole 130 and reinforcing member 140 that each key device 100 is included is not with real shown in Fig. 2 B The mode of applying is limited, and can flexibly increase and decrease because of actual demand.

A referring to figure 2., balancing pole 130 include ontology 131 and two bending parts 132 (merely exemplary mark one).Two bendings Portion 132 is separately connected the both ends of ontology 131, and opposing body 131 bends.Reinforcing member 140 includes sheet body 141.Balancing pole 130 In a welding manner, such as: spot welding or arc welding connection, but not limited to this, also may be used for the sheet body 141 of ontology 131 and reinforcing member 140 With bury penetrate, wrap penetrate, it is glued, the modes such as crimping connect.Specifically, having an at least welding area between ontology 131 and sheet body 141 F, whereby, on the solderable ontology 131 for being connected to balancing pole 130 of the sheet body 141 of reinforcing member 140.Ontology 131 and any sheet body 141 it Between the quantity of welding area F be not limited with embodiment shown in Fig. 2A, can flexibly increase and decrease because of actual demand.

As shown in Figure 2 B, keycap 120 includes multiple first convergence parts 121 (merely exemplary mark one).Balancing pole 130 Ontology 131 is rotationally connected with the first convergence part 121 of keycap 120.When one end of keycap 120 is pressed, balancing pole 130 Lower pressure can be passed to the other end of keycap 120 by press-side, the whole downwardly bottom plate 110 of guide keycap 120 is mobile.

In some embodiments, the bridging mode of ontology 131 and keycap 120 for example adopts axis (i.e. ontology 131) and axis hole The mode that (i.e. the first convergence part 121) matches, but not limited to this.

As shown in Figure 2 C, bottom plate 110 has multiple hooks 111 (merely exemplary mark one).Each reinforcing member 140 includes Hook part 142 (A referring to figure 2.).The hook part 142 of each reinforcing member 140 is connect with sheet body 141, and hook part 142 and sheet body 141 it Between shape have angle, with the hook 111 of corresponding bottom plate 110 engage.Two bending parts 132 of each balancing pole 130 also with Second convergence part 112 (merely exemplary mark one) linking of bottom plate 110.

In some embodiments, the hook part 142 of reinforcing member 140 can opposed bottom 110 and the movement of hook 111 and rotation.

D referring to figure 2., keycap 120 are set to the top of bottom plate 110.Balancing pole 130 is connected with reinforcing member 140 in keycap Between 120 and bottom plate 110.The ontology 131 of balancing pole 130 is rotationally connected with the first convergence part 121 of keycap 120.Reinforcement 141 one end of sheet body of part 140 is connect with balancing pole 130, and the other end is connect with hook part 142.The hook part 142 of reinforcing member 140 with it is right The hook 111 for the bottom plate 110 answered engages.When keycap 120 is pressed, the hook part 142 of an at least reinforcing member 140 can be used as fulcrum Balancing pole 130 is guided to decline, make the sheet body 141 of reinforcing member 140 and the whole downwardly bottom plate 110 of keycap 120 it is mobile thus have Effect promotes the gearing of keycap 120, reduces the case where keycap 120 deforms.

Conceived according to this case, as shown in Figure 2 C, existing long key keycap fulcrum is balancing pole and bottom plate joining place, is changed through this case After good, 120 position of the fulcrum of keycap moves to reinforcing member 140 and engages place with bottom plate 110.In other words, fulcrum and 110 center of bottom plate are triggered The distance in portion 150 shorten to distance L2 by original distance L1.Obviously, through reinforcing member 140 is added on balancing pole 130, make The trigger unit 150 for obtaining 120 fulcrum of keycap and bottom plate 110 is close apart from change, therefore when keycap 120 is by pressed by external force, strength transmission The problem of gearing property can be promoted, and be further conducive to the conducting triggering of key, while can also be improved thin-type keycap deformation.
