Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1-5, a specific embodiment of the present invention is a low noise key structure, including a key base 1 and a key shaft 2, a reset piece 3 is further disposed between the key base 1 and the key shaft 2, a buffering soft rubber 4 is further disposed on a side surface of the key shaft 2, the key shaft 2 is embedded in the key base 1, when the key shaft 2 is pressed, an upper portion of the buffering soft rubber 4 touches an upper edge of the key base 1, when the key shaft 2 is released, the reset piece 3 drives the key shaft 2 to reset upwards, and a lower portion of the buffering soft rubber 4 touches a lower edge of the key base 1; when the key shaft is pressed down and loosened, the soft buffering glue touches the key seat, and the buffering and silencing effects are achieved.
Specifically, the soft buffer glue 4 comprises a fixing part 401, an upper buffer part 402 and a lower buffer part 403, the fixing part 401 is embedded in the key shaft 2, the lower buffer part 403 is of a convex wedge-shaped structure, and the upper buffer part 402 is of an L-shaped structure; the fixed part of the soft buffering rubber is embedded in the key shaft, so that the space is saved, and meanwhile, the sound generated when the soft buffering rubber collides with the key base is ingeniously eliminated by the upper buffering part and the lower buffering part. The convex lower buffer part with the wedge-shaped structure can increase the contact area, effectively increase the buffer effect and reduce the noise during resetting.
As shown in fig. 4, when the soft buffer rubber touches the key pad, the connection manner of the embodiment is as follows: an upper notch 101 is arranged at the edge of the upper part of the key base 1, a lower opening 102 is arranged at the lower part of the key base 1, when the key base is pressed down, the lower edge of the upper buffer part 402 is contacted with the lower edge of the upper notch 101, and when the key base is reset, the upper edge of the lower buffer part 403 is contacted with the upper edge of the lower opening 102; the middle of the key base 1 is provided with a limiting groove 103, the limiting groove 103 is located at the upper edge of the lower opening 102, and the lower buffer part 403 corresponds to the limiting groove 103. Through the cooperation of spacing groove and lower buffering portion, can effectively increase buffering effect, lower buffering portion is the wedge structure, and the spacing inslot also is the wedge structure, area of contact when can effectively increase the striking.
In order to enable the soft buffering rubber to be matched with the key shaft more tightly, the lower parts of two sides of the key shaft 2 are provided with convex fixing bulges 201, the fixing bulges 201 are of wedge-shaped structures, and the lower buffering parts 403 are correspondingly attached to the fixing bulges 201. The fixing bulge of the wedge-shaped structure facilitates downward extrusion during installation of the key shaft, the key shaft is automatically locked after installation, and the key shaft cannot pop out of the key seat.
In order to facilitate the combination of the balance bar and the key seat, a first mounting groove 5 is formed in one side of the key seat 1, a second mounting groove 6 is further formed in one side of the upper portion of the key shaft 2, a balance bar 7 is embedded in the first mounting groove 5 and the second mounting groove 6, and the mounting mode of the key seat and the balance bar is not limited to the groove structure in the embodiment and can be a through hole structure.
Reset in this embodiment 3 for the spring structure for kick-backing resets, and buffering flexible glue 4 is the silica gel structure, and noise cancelling effect is better. The buffering soft rubber 4 and the key shaft 2 are of a secondary injection molding structure, so that the surface of a product is full of soft feeling, and the noise reduction, shock absorption and waterproof functions of the product are improved.
This application is a button that structure is ingenious, through installing embedded buffering flexible glue, simple structure neither can increase the button volume, avoids the direct and key seat striking of key shaft simultaneously effectively, and then has reduced the noise when strikeing and takes place, can effectively reduce the noise, still have certain shockproof function simultaneously, can not influence the feeling of pressing moreover, and the buffering flexible glue of silica gel material is more durable.
The above, only do the preferred embodiment of the present invention, not used to limit the present invention, all the technical matters of the present invention should be included in the protection scope of the present invention for any slight modification, equivalent replacement and improvement of the above embodiments.
