Embodiment
For making purpose, structure, characteristic and function thereof that further understanding arranged, cooperate embodiment to specify as follows now to the utility model.
Please refer to Fig. 1, the sketch map of the keyboard 1 that Fig. 1 is disclosed for the utility model embodiment.Keyboard 1 includes base plate 10, a plurality of first button 20 and a plurality of second button 30, and wherein first button 20 is the multiple key, and second button 30 then is other buttons beyond the multiple key.
Please refer to Fig. 2 and Fig. 3, Fig. 2 is installed on the sketch map on the base plate 10 for keyboard 1 first button 20 wherein of Fig. 1, and Fig. 3 is the element exploded perspective view of Fig. 2.First button 20 comprises keycap 22 and connecting rod 24, and connecting rod 24 has body 243, first arm 241 and second arm 242.Body 243 is incorporated into the bottom of keycap 22, and 242 of first arm 241 and second arms extend perpendicular to body 243 from body 243 two ends respectively.In this embodiment, connecting rod 24 preferably is the U type.Base plate 10 has a plurality of supporting constructions 11 with respect to a plurality of first buttons 20, is used for combining with the connecting rod 24 of each first button 20, and wherein each supporting construction 11 comprises first support portion 12 and second support portion 14.First support portion 12 has first perforate, 121 second support portions 14 and then has second perforate 141.When mounted; First arm 241 of connecting rod extends in first perforate 121 of first support portion 12; 242 of second arms extend in second perforate 141 of second support portion 14, and when first button, 20 pressurizeds and relatively base plate 10 moves down the (L of Fig. 4, Fig. 5 for example along vertical direction
1Direction) or along the vertical direction (L of Fig. 4, Fig. 5 for example that rises
2Direction) time; Connecting rod 24 can on average be transmitted to the strength of first button, 20 pressurizeds whole first button 20; And being kept, first button 20 flatly moves up and down, and first arm 241 and the supported structure 11 support restrictions in first perforate 121 and second perforate 141 respectively of second arm 242.
Please refer to Fig. 4, Fig. 4 is positioned at the sketch map of first embodiment of first support portion 12 (or second support portion 14) for first arm 241 (or second arm 242) of connecting rod 24.As shown in Figure 4, first support portion 12 has first depressed part 122 in addition, is formed at the periphery of first perforate 121, and first depressed part 122 is arc-shaped structure, and its radius of curvature is first radius R
1 First arm 241 of connecting rod 24 is for cylinder and have second radius R
2, second radius R of first arm 241 wherein
2First radius R greater than first depressed part 122
1In the embodiment of Fig. 4, when first button, 20 pressurizeds moved up and down, first arm 241 mainly can be along L
1L
2Vertical direction slightly move, therefore produce collision with first support portion 12.In this embodiment, first depressed part 122 is positioned at the periphery that first perforate 121 is vertically gone up, and therefore works as first arm 241 along L
1L
2Vertical direction move and when producing collision with first support portion 12, first arm 241 only produces some contact-impacts in the cause of first perforate, 121 internal causes, first depressed part, 122 external forms with first support portion 12.Second support portion 14 also has second depressed part 142; Be formed at the periphery of second perforate 141, second arm 242 of connecting rod 24 is then similar with aforementioned first arm 241 and first support portion 12 with the relation that the relative structure of second support portion 14 and point contact.Thus, can significantly reduce the contact area of connecting rod 24 and supporting construction 11, produce when moving up and down, the noise that the some way of contact between connecting rod 24 and the supporting construction 11 can effectively reduce collision and produced pushing first button 20.
Please refer to Fig. 5, Fig. 5 is positioned at the sketch map of second embodiment of first support portion 12 ' (or second support portion 14 ') for first arm 241 (or second arm 242) of connecting rod 24.As shown in Figure 5, first support portion 12 ' has a plurality of first depressed parts 122 ', forms and is covered with in the periphery of first perforate 121, and when first button, 20 pressurizeds moved up and down, first arm 241 was except mainly along L
1L
2Vertical direction slightly move outside, also might produce with first support portion 12 ' and collide in other directions.Therefore in this embodiment, be covered with in a plurality of first depressed part, 122 ' formed external forms of first perforate, 121 peripheries and make first arm 241 and first support portion 12 ' only produce some contact-impacts.Second support portion 14 ' also has second depressed part 142 '; Form and be covered with, second arm 242 of connecting rod 24 and the relative structure of second support portion 14 ' and to put the relation that contacts then similar with aforementioned first arm 241 and first support portion 12 ' in the periphery of second perforate 141.Thus; First depressed part 122 ' among second embodiment and second depressed part 142 ' can significantly reduce the contact area of connecting rod 24 and first support portion 12 ' and second support portion 14 '; Produce when moving up and down the noise that the some way of contact between the connecting rod 24 and first support portion 12 ' and second support portion 14 ' can effectively reduce collision and produced pushing first button 20.
Please refer to Fig. 6, it is installed on the sketch map of first support portion 12 and second support portion 14 for connecting rod 34 another embodiment.In the embodiment of Fig. 6, connecting rod 34 also has body 343, first arm 341 and second arm 342.342 of first arm 341 and second arms stretch out from body 343 two ends respectively, and have the obtuse angle angle theta with body 343 respectively.Therefore in this embodiment, connecting rod 34 also makes first arm 341 and second arm, 342 relative bodies 343 stretch out for U type and its obtuse angle angle theta.When first arm 341 and second arm 342 extend corresponding supporting construction respectively; Can make connecting rod 34 prop up supporting construction; When first button 20 was pushed, the collision phenomenon that only supports after reducing connecting rod 34 and supporting construction being separated further reduced the possibility that noise produces.
In the keyboard that the utility model disclosed, on the base plate in order to the support portion perforate of the connecting rod of support and connection between keycap and base plate, process depressed part, when making connecting rod penetrate perforate, contact with a mode that contacts with the periphery of perforate.When the button on the keyboard vertically presses down or replys, only with a contact-impact, can effectively reduce the noise of contact-impact thus between connecting rod and the perforate, make button and keyboard when operation, have the low noise performance.
The utility model is described by above-mentioned related embodiment, yet the foregoing description is merely the example of implementing the utility model.Must be pointed out that the embodiment that has disclosed does not limit the scope of the utility model.On the contrary, change and the retouching in spirit that does not break away from the utility model and scope, done all belong to the scope of patent protection of the utility model.
