Abstract
The utility model discloses a compound silica gel button, include supporting part, elastic connection portion, pressing splenium and axle core that adopt silica gel material integrated into one piece, pressing splenium still has the non-silica gel material that adopts the method of burying or jet-out shaping and silica gel button body composite forming and the compound portion that hardness is greater than the silica gel material, compound portion and axle core are along pressing the coaxial setting that corresponds of direction, and set up and be in press one side that the splenium corresponds the key cap or correspond one side of axle core. The utility model discloses because press the one side of splenium contact key cap or correspond one side complex entering non-silica gel material and hardness of axle core to be greater than the complex portion of silica gel material at the silica gel button, the existence of complex portion makes the bounce of pressing the splenium more excellent to the Click and the life-span of button have effectively been improved.
Description
Technical Field
The utility model relates to a keyboard technical field, in particular to compound silica gel button.
Background
The thin film keyboard mainly comprises a keycap, scissor feet (an X-shaped support) arranged below the keycap and a silica gel key, wherein the X-shaped support is used for fixing and stabilizing the keycap and is matched with a thin film circuit layer (namely a flexible circuit board) arranged at the bottom; referring to fig. 1, the silicone key is in the shape of an inverted bowl, and mainly includes a supporting portion S1, an elastic connecting portion S2, a pressing portion S3, and a shaft core S4, the supporting portion S1 of the bowl opening is mounted on the thin film circuit layer, and the pressing portion S3 of the bowl bottom is used for contacting the keycap. When the keycap is pressed, the pressing portion S3 of the silica gel key firstly contacts the keycap and is driven by the keycap to trigger downwards, and then the shaft core S4 inside the pressing portion S3 applies pressure to drive the electrode contacts in the thin film circuit layer to contact with each other to realize conduction, and the elastic connecting portion S2 of the silica gel key enables the pressing portion S3 to reset and drives the keycap to reset. Because the silica gel key of the prior art adopts the integral injection molding of silica gel material, referring to fig. 2, the silica gel key has low rebound Force (Return Force) in the using process, thereby affecting the Click and the service life of the key, and shortening the difference value of P2-P4, thereby causing unsatisfactory pressing performance.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a compound silica gel button, include supporting part, elastic connection portion, splenium and axle core that adopt silica gel material integrated into one piece, splenium still has the compound portion that non-silica gel material and hardness are greater than the silica gel material, compound portion and axle core are along pressing the coaxial setting that corresponds of direction.
The composite part is arranged on one side of the pressing part corresponding to the keycap; or the composite part is arranged on one side of the pressing part corresponding to the shaft core.
When the composite silica gel key is integrally injection molded, the composite part is formed with the silica gel key body by adopting an embedding or injection molding method.
Through the technical scheme, the utility model discloses because press the one side of splenium contact key cap or correspond one side complex entering non-silica gel material and hardness of axle core to be greater than the complex portion of silica gel material at the silica gel button, the existence of complex portion makes the bounce of pressing the splenium more excellent to the Click and the life-span of button have effectively been improved.

Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
Referring to fig. 3-5, the present invention provides a composite silicone key, which includes a supporting portion S1, an elastic connecting portion S2, a pressing portion S3 and a shaft core S4, wherein the supporting portion S1, the elastic connecting portion S2, the pressing portion S3 and the shaft core S4 are integrally formed from silicone, the pressing portion S3 further includes a composite portion S5 which is not made from silicone and has hardness greater than that of the silicone, and the composite portion S5 and the shaft core S4 are coaxially and correspondingly disposed along a pressing; the support portion S1 is provided with a discharge hole S6.
Wherein, the complex portion S5 is disposed on a side of the pressing portion S3 corresponding to the keycap, as shown in fig. 3 and 4; alternatively, the composite portion S5 is provided on the side of the pressing portion S3 corresponding to the shaft center S4, as shown in fig. 5.
When the composite silicone key is integrally injection molded, the composite part S5 is composite molded with the silicone key body by using an embedding or injection molding method. The embedding mode is generally that the hard non-silica gel composite part S5 is directly embedded into a mold before injection molding, and then the silica gel key body is integrally injection molded; the injection molding method is to injection mold the composite part S5 after the silicone key body is injection molded.
The utility model discloses because the one side of pressing the splenium contact key cap or corresponding axle core at the silica gel button compound non-silica gel material of entering and hardness are greater than the compound portion S5 of silica gel material, compound portion S5 is because hardness is greater than the hardness of silica gel material, it is pressing splenium S3 when pressing down and producing elastic deformation, make according to splenium S3 inside deformation pressure increase because the existence of compound portion S5, make the bounce of pressing splenium S3 more excellent, thereby the Click and the life-span of button have effectively been improved.
The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to the above-described embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
