Detailed Description

In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention is described in detail with reference to the accompanying drawings and the detailed description.

The utility model discloses a double-colored key cap, refer to fig. 1-2, including key cap body 2 and the key cap upper cover plate 1 that is located key cap body 2 top. Wherein, key cap body 2 sets up to different colours and forms through double-colored moulding plastics with key cap upper cover plate 1. Specifically, the key cap body 2 and the key cap upper cover plate 1 can be integrally injection molded to simplify the molding process, and after the integral injection molding, the key cap body 2 and the key cap upper cover plate 1 can be connected in a seamless manner; of course, the key cap body 2 and the key cap upper cover plate 1 can also be obtained by assembling after being respectively injection molded.

In this embodiment, the size of key cap upper cover plate 1 slightly is less than key cap body 2, each side of key cap upper cover plate 1 all is equipped with downwardly extending's peg graft pole 11, each side of key cap upper cover plate 1 includes but not limited to two peg graft poles 11, and two peg graft pole 11 symmetries locate the both sides about 1 side of key cap upper cover plate, each side of key cap body 2 all be equipped with peg graft pole 11 assorted spliced eye 21, through peg graft pole 11 and spliced eye 21's accordant connection, realize being connected and the equipment of key cap upper cover plate 1 and key cap body 2, wherein, peg graft pole 11 that two symmetries set up makes key cap upper cover plate 1 more firm with being connected of key cap body 2, thereby the structure of double-color key cap is more stable.

In practical application, after the insertion rod 11 is connected with the insertion hole 21 in a matching manner, the key cap upper cover plate 1 forms the upper surface of the key cap, and the key cap body 2 forms each side surface of the key cap, and because the key cap body 2 and the key cap upper cover plate 1 are different in color, the upper surface of the key cap (except the character part 22) and each side surface of the key cap form a vivid color difference, so that the color of the key cap is richer, and the key cap is simple in structure and more reasonable in design.

Wherein, the key cap body 2 is equipped with the protruding character portion 22 who stretches out the upper surface, and key cap upper cover plate 1 is equipped with the fretwork portion 12 of overlapping character portion 22, and the colour difference through the character portion 22 of key cap body 2 and key cap upper cover plate 1 makes the character show on key cap upper cover plate 1, and key cap body 2 and key cap upper cover plate 1 are connected the back, and character portion 22 flushes with the surface of key cap upper cover plate 1, can improve the wearability of character portion 22.

Referring to fig. 2-3, the key cap body 2 includes a housing 23 and a connecting column 24 disposed in the housing 23, the housing 23 includes a panel 231 and a side surface body 232 connected to a side of the panel 231, an upper end of the connecting column 24 is connected to a center of a lower surface of the panel 231, so that an overall structure of the key cap body 2 is more stable, a lower end of the connecting column 24 extends downward out of the side surface body 232, and the connecting column 24 is provided with a hollow structure 241 arranged along an axis, so that the lower end of the connecting column 24 extending out of the side surface body 232 is connected to an external key shaft through the hollow structure 241.

Wherein, the upper end of the connecting column 24 is further provided with a reinforcing rib 242 connected with the side surface body 232, and the top of the reinforcing rib 242 is connected at the diagonal of the lower surface of the panel 231. The external force that its bore of strengthening rib 242 that the diagonal angle set up is bigger, and the flank body 232 of key cap body 2 and the enhancement effect of panel 231 are better, difficult emergence deformation, long service life.

For the comfort that improves double-colored key cap use, still all set up from both sides limit to the concave arc type concave surface 3 of establishing in the middle at the upper surface of key cap body 2 and key cap upper cover plate 1 to human finger of laminating, feel better.

In practical application, for avoiding the defect that traditional ABS is not wear-resisting and the oil is beaten, the key cap body 2 and the key cap upper cover plate 1 of this key cap are the polybutylene terephthalate material to can further improve the wear resistance of key cap, can also avoid the oil condition to appear after long-time the use, improve the quality of this key cap.

In practical application, for reduction in production cost, key cap body 2 also can be the ABS material, but when reduce cost, for the wearability that improves the key cap, make the key cap surface not the oiling to improve the quality of key cap, key cap upper cover plate 1 still adopts the polybutylene terephthalate material of moulding plastics.

While preferred embodiments of the present invention have been described, additional variations and modifications of these embodiments may occur to those skilled in the art once they learn of the basic inventive concepts. It is therefore intended that the following claims be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the embodiments of the invention.

The technical solution provided by the present invention is described in detail above, and the principle and the implementation of the present invention are explained by applying specific examples, and the description of the above examples is only used to help understanding the method and the core idea of the present invention; meanwhile, for the general technical personnel in the field, according to the idea of the present invention, there are changes in the specific implementation and application scope, to sum up, the content of the present specification should not be understood as the limitation of the present invention.
