Abstract
The utility model relates to a keyboard, and cooperated with a key, a circuit board and an electricity-conducting base plate, is arranged on an electronic device. The key is provided with a key cover and a base seat provided with a first mounting section and a second mounting section. The keyboard comprises a plurality of elastic bodies and a base provided with a plurality of convex buffer units. Provided with a pressure-receiving section and a striking section, the elastic body is protruded out of the base and is arranged at the mounting section of the base seat. The buffer units are arranged at the second mounting section of the base seat, so that the base is fixed between the base seat of the key and the circuit board is arranged between the electricity-conducting base plate and the base of the elastic body.
Description
The utility model relates to a kind of key board unit, and this device can reduce the noise that key tap produces, and absorbs to knock the vibrations that keyboard produces.
Electronic installation all disposes keyboard, in the use during key tap key of button lid knock directly that keyboard base produces noise, vibrations are unavoidable.Key device as No. the 80206310th, Taiwan patented claim, it mainly comprises key lid, saddle, linkage assembly, base and spring, can collision make a noise and produce the vibrations between key lid, saddle and base when this key device is pushed, spring also can produce identical problem with the collision of saddle and base.In addition, as No. the 83204123rd, Taiwan patented claim and United States Patent (USP) the 5th, 457, No. 297 disclosed key devices, it adopts the key ring plate of elastic silica gel material to replace traditional spring, can reduce the height of button, and absorption portion vibrations and reduce some noises, but main noise, vibrations derive from the direct collision between key lid, connecting rod and base, still can't eliminate.Other relevant prior aries can be referring to No. the 84218262nd, 84214265 and 85202834, Taiwan patented claim, and United States Patent (USP) the 4th, 580,022,4,902,862,5,278,372,5,278,374,5,382,762,5,399,822,5,463,195,5,466,901,5,488,210,5,504,283,5,512,719,5,555,971 and 5,562, No. 203 etc.
Therefore, the purpose of this utility model is to provide a kind of key board unit with cushioning effect, and this key board unit provides elasticity except that can be button, also can eliminate noise and the vibrations that button is sent in use, thereby solves prior art problems.
The purpose of this utility model is achieved in that promptly provides a kind of key board unit, comprising: at least one key device, described key device have key lid and base at least, and described base has first installing department and second installing department; Circuit board and conductive soleplate; And elastic device, it comprises base portion and a plurality of elastic body, convexes with a plurality of buffer part on the described base portion, described elastic body is convexly equipped with from described base portion, has compression zone on it and knocks portion; Described elastic body is installed in described first installing department of described base, described buffer part is installed in described second installing department of described base, described base portion is fixed between described button base and described circuit board, and described circuit board is installed between described elastic body's described base portion and described conductive soleplate.
The advantage of the utility model device is that it can reduce the noise that key tap produces, and absorbs to knock the vibrations that keyboard produces, and can obtain the sense of touch of good resilience when using keyboard.
Below with reference to accompanying drawing, embodiment of the present utility model is described, wherein:
Fig. 1 is the three-dimensional exploded view of key board unit in the utility model key board unit;
Fig. 2 is a key board unit combination diagrammatic cross-section in the utility model key board unit; With
The diagrammatic cross-section of the utility model key board unit buffer part when Fig. 3 presses down for the key lid.
Referring to Fig. 1 and Fig. 2, wherein key board unit 99 comprises key device 10, elastic device 20, film circuit board 30 and conductive soleplate 40.Wherein key device 10 mainly comprises key lid 12, cross link 14 and base 16.Key lid 12 is provided with projection 122, be used for being connected with elastic device 20, on base 16, be provided with first through hole 162, can pass and cover 12 for the part of elasticity device 20 and be connected with key, base 16 also is provided with second through hole 164 at periphery, can be used as location and noise reduction, removes the foundation (will describe in detail in the back) of shake.Elastic device 20 comprises elastic body 22, compression zone 24, knocks portion 26 and base portion 28.Wherein convex with a plurality of elastic bodies 22 on the base portion 28, elastic body 22 has a dented space 221, and it can be installed in first through hole 162 of aforementioned keys device 10 bases 16.Along elastic body's 22 vertical direction, be provided with compression zone 24 towards extending away from the direction of base portion 28, have a circular port 242 on it, can be used for connecting the projection 122 of previous key lid 12.In dented space 221, be provided with the portion of knocking 26 towards the direction of leaving compression zone 24, it is a cylinder, in order to knocking film circuit board 30, thereby makes the circuit 32 on it contact the formation current path with conductive base plate 40; Base portion 28 is provided with buffer part 29 near elastic body 22, can be installed in second through hole 164 of aforementioned keys device 10 bases 16.
As shown in Figure 3, when user's pressing key lid 12 moved down, the compression zone 24 of elastic device 20 was subjected to the compressing of key lid 12.When key lid 12 is displaced downwardly to extreme lower position, can cause elastic body 22 distortion, make the dented space 221 interior portions of knocking 26 knock the circuit 32 of film circuit board 30, make its compressing conductive soleplate 40, thereby constitute the circuit of conducting.At this moment, key lid 12 can collide the buffer part 29 that is provided with at elastic device 20 peripheries, because elastic device 20 is made for the elastomeric flexible silica gel material is one-body molded, has the function of shock-absorbing noise reduction, therefore, buffer part 29 can absorb vibrations and the noise thereof that is produced by 12 collisions of key lid.In addition, key board unit of the present utility model can significantly reduce noise and the vibrations that key tap produced in the past, and improves the sense of touch when using.
