For the technology contents that the present invention will be described in detail, construction feature, the effect realized, below in conjunction with embodiment and match
Attached drawing is closed to be explained in detail.
In the description of the present invention, it is to be understood that, the instructions such as term "upper", "lower", "top", "bottom", "inner", "outside"
Orientation or positional relationship be based on the orientation or positional relationship shown in the drawings, be only for ease of description the present invention and simplification retouch
It states, rather than indicates or imply signified device or element must have a particular orientation, be specific azimuth configuration and operation,
It thus should not be understood as the limitation to present invention protection content.
It please refers to Fig.1 and Fig. 2, the invention discloses a kind of pressing pieces 1 for key switch, including main part 11 and shape
It is equipped with backstop sliding block 13, main body at 111 convex of at least one side in the press section 12 of the top surface of main part 11, main part 11
The first resilient snubber 14 is arranged in portion 11, the first resilient snubber 14 has the buffer part being located at right over backstop sliding block 13
141.Preferably, under non-pressed state, buffer part 141 is located on backstop sliding block 13, naturally it is also possible between backstop sliding block 13
Form small interval.In the present embodiment, press section 12 is set to the centre position of the top surface of main part 11, and the upper end just can be with
The button cap (not shown) of keyboard is chimeric, and press section 12 is cross, but should not be as limit.
Specifically, there is main part 11 two side being oppositely arranged, two side to have two opposite sides 111, both sides
Face 111 distinguishes outside projection and forms a backstop sliding block 13, correspondingly, the first resilient snubber 14, which has, is located at two backstops
Two buffer parts 141 right over sliding block 13, but should not be as limit；For example, it is also possible to only corresponding two backstop sliding blocks 13 it
One position is equipped with buffer part 141；Certainly, the quantity of the backstop sliding block 13 per one side 111 projection is also not necessarily limited to one, but,
It is not limited to each backstop sliding block 13 and is correspondingly arranged on buffer part 141.
Referring to Fig. 2, specifically, the periphery on the top of main part 11 is recessed a sleeved part 15, the first elastic buffer
There is part 14 elasticity to be set in the ring body 142 in sleeved part 15；But it should not be as limit, in some embodiments, it is also possible to will
First resilient snubber 14 is directly set in the periphery of main part 11.Preferably, the lower end of sleeved part 15 and backstop sliding block 13
Upper end is generally in same level.
Specifically, ring body 142 has buffer part 141；That is, buffer part 141 is the component part of ring body 142.
Specifically, the outer profile of sleeved part 15 substantially assumes diamond in shape, sleeved part 15 has opposite both ends angle 151, both ends angle
At least one of 151 is opposite with the middle part of backstop sliding block 13, and when ring body 142 is set in sleeved part 15, ring body 142 is sticked two
At least one of the both ends at end angle 151 is outwardly protruded to the surface of corresponding backstop sliding block 13 to form buffer part 141.
In the present embodiment, both ends angle 151 is opposite with the middle part of corresponding backstop sliding block 13 respectively, and ring body 142 is sticked at both ends angle 151
Both ends are outwardly protruded to the surface of corresponding backstop sliding block 13, and form two buffer parts 141, but should not be as limit.
Specifically, the external end edge at the both ends angle 151 of sleeved part 15 it is opposite with main part 11 two sides 111 it is substantially equal
Together, it thereby designs, the buffer part 141 at both ends angle 151 that ensures to be sticked can be protruding to the surface of backstop sliding block 13, and can
It avoids causing both ends angle 151 to collide with upper cover 2 beyond the side 111 of main part 11 due to both ends angle 151.
Specifically, the first resilient snubber 14 is rubber material, in the present embodiment, the first resilient snubber 14 is silicon
Glue, but should not be as limit.
Referring to Fig. 3, in another embodiment, buffer part 141 by ring body 142 at least one protruding formation, but
It should not be as limit.
Fig. 4 to Fig. 9 is please referred to, the invention also discloses a kind of key switch 100, including upper cover 2, is combined with upper cover 2
Pedestal 3, the switch terminal set 4 in upper cover 2 and pedestal 3 and elastic component 5, further include pressing piece 1 as described above；Pressing
Part 1 is set in the movable chamber 21 that upper cover 2 is formed with pedestal 3, and upper cover 2 offers a through-hole 22, and press section 12 is upward by through-hole 22
It stretches out, pedestal 3 is equipped with hollow cylinder 31, and pressing piece 1 further includes the stopper posts 16 extended downwardly by 11 middle part of main part, stopper posts
16 insertion hollow cylinders 31 can simultaneously axially move in hollow cylinder 31, and elastic component 5 is sheathed on stopper posts 16 and hollow cylinder
31 outside.Wherein, through-hole 22 is set to the center of upper cover 2；Switch terminal 4 includes static terminal 41 and moved end 42, static side
Son 41 and moved end 42 are set to the side of pedestal 3；Elastic component 5 is spring, but should not be as limit.
Referring to Fig. 5, specifically, 3121 inside of bottom wall of hollow cylinder 31 is equipped with the second resilient snubber 6；Thereby set
Meter, when stopper posts 16 move downward, stopper posts 16 compress the second resilient snubber 6 so that stopper posts 16 will not directly and bottom
Wall 3121 contact, but by the second resilient snubber 6 with bottom wall 3121 contacted, to play the role of buffering,
The noise generated by collision is thereby reduced, while can also be avoided because of pressing piece 1 and bottom wall 3121 caused by hard contact
Abrasion.In the present embodiment, the profile of the second resilient snubber 6 is generally cylindrical, but should not be as limit；More specifically
, hollow cylinder 31 includes being located at the column body 311 inside pedestal 3 and the lower prop 312 beyond 3 bottom surface of pedestal, lower prop 312
Bottom formed bottom wall 3121.
Referring to Fig. 6, specifically, offering sliding slot 321 on the side wall 32 of pedestal 3, backstop sliding block 13 is slidably mounted
In sliding slot 321.
Hereinafter, the operation principle of the key switch 100 of the present invention is described in detail in conjunction with Fig. 1-Fig. 9.
In pressing, the press section 12 of pressing piece 1 is pressed, and pressing piece 1 in movable chamber 21 in axially moving downwards, bullet
Property part 5 compressed, until stopper posts 16 are pressed on the second resilient snubber 6, be pushed at this point, moved end 42 is pressed part 1
Side and with static terminal 41 be detached from, i.e., key switch 100 is become the state of Fig. 9 from Fig. 5；When cancelling pressing, the pressing of pressing piece 1
Pressing force in portion 12 disappears, and pressing piece 1 is axial in making upwards in movable chamber 21 under the action of the elastic restoring force of elastic component 5
Movement, until the buffer part 141 of the first resilient snubber 14 is mutually compressed with upper cover 2, i.e., key switch 100 becomes Fig. 5 from Fig. 9
State, at this point, moved end 42 also restores and the contact of static terminal 41.
Compared with prior art, pressing piece 1 of the invention in main part 11 by being arranged the first resilient snubber 14, and
One resilient snubber 14 has the buffer part 141 positioned at the surface of backstop sliding block 13, when pressing piece 1 moves upwards reset,
Backstop sliding block 13 will not be contacted directly with upper cover 2, but be contacted with upper cover 2 by buffer part 141, to play buffering
Effect, thereby reduce the noise generated by collision, while can also avoid because of pressing piece 1 caused by hard contact and upper
The abrasion of lid 2.
Above disclosed is only the preferred embodiments of the present invention, cannot limit the right model of the present invention with this certainly
It encloses, therefore according to equivalent variations made by scope of the present invention patent, still falls within the range that the present invention is covered.
