Description

Keyboard key structure

This creation is about a key structure, and especially a keyboard key structure.

As e-sports games become more popular and popular, players’ demand for video game equipment specifications has also increased. This has led to the emergence of a mechanical keyboard on the market. This mechanical keyboard has a mechanical keyboard with a long pressing stroke, a precise touch and pressing feel, and a long service life.式buttons.

The traditional mechanical key includes an upper shell, a lower shell, a pressing shaft, a spring, and a cap. The upper shell and the lower shell are assembled with each other and a cavity is formed inside. The pressing shaft and the spring are accommodated in the cavity, and the pressing shaft The top end is exposed on the upper shell, the spring is elastically supported between the bottom end of the pressing shaft and the lower shell, and the cap is installed on the top end of the pressing shaft.

However, the above-mentioned upper shell is made of plastic injection molding, so if the assembly structure between the upper shell and the lower shell is too complicated, it will be difficult to demold the upper shell or the appearance design is limited, which will result in manufacturing Problems such as high cost and reduced yield.

In view of this, the creator has focused on the above-mentioned existing technology, specially researched and cooperated with the application of academic theory, and tried his best to solve the above-mentioned problems, which became the goal of the creator's improvement.

This creation provides a keyboard key structure, which utilizes the hollow card slot of the upper shell to be easily demolded during the plastic injection molding process, so as to achieve the keyboard key structure with the appearance design freedom of the upper shell, save the finished product and improve the yield rate, etc. advantage.

In this creative embodiment, this creative system provides a keyboard key structure, including: a lower shell with a base, the base extending upwards with at least one hook; an upper shell assembled on top of the lower shell , The upper housing has a top wall, the top wall is provided with a through opening and at least one hollow slot, the at least one hollow slot penetrates the top surface of the top wall, and the at least one hook is engaged with the At least one hollow slot; a pressing shaft accommodated between the lower shell and the upper shell, the top end of the pressing shaft penetrates the through opening; and a spring elastically supported on the lower shell and the upper shell The press between the shafts.

Based on the above, the assembly structure of the lower casing and the upper casing is simple, and the hollow slot of the upper casing is easily demolded during the plastic injection molding process, so that the design size of the upper casing can be reduced accordingly, and the appearance of the upper casing The shape design is also relatively free and unrestricted, so that the keyboard key structure has the advantages of freedom of appearance design of the upper shell, saving of finished products, and improved yield.

The detailed description and technical content of this creation will be explained as follows with the drawings. However, the attached drawings are only for illustrative purposes and are not used to limit this creation.

Please refer to FIG. 1 to FIG. 4. This creative department provides a keyboard key structure. The keyboard key structure 10 mainly includes a lower shell 1, an upper shell 2, a pressing shaft 3 and a spring 4.

The lower shell 1 has a base 11, the base 11 extends upwards with one or more hooks 12 and a protruding column 13. The number of the hooks 12 in this embodiment is two, and each hook 12 has a straight piece 121 and a self-standing piece. A protrusion 122 extends from the end of the piece 121, and the protrusion 13 is disposed between the two upright pieces 121.

The upper casing 2 is assembled above the lower casing 1. The upper casing 2 has a top wall 21 and an annular peripheral wall 22 surrounding the periphery of the top wall 21. The top wall 21 is provided with a through opening 23 and one or more open spaces. The card slot 24, the number of the hollow card slots 24 in this embodiment is two, the two hollow card slots 24 are arranged on both sides of the through opening 23, and each hook 12 is engaged with each hollow card slot 24 to make The shell 1 and the upper shell 2 are assembled up and down, and a cavity s is enclosed inside.

The detailed description is as follows. One end of each hollow groove 24 penetrates the top surface 211 of the top wall 21 and the other end penetrates the inner wall surface 221 of the annular peripheral wall 22. The bottom of each hollow groove 24 has a bottom wall 241.

Wherein, when the upper housing 2 corresponds to the cover of the lower housing 1, the protrusions 122 are received in the hollow grooves 24 and are stopped and positioned by the bottom walls 241, so that the lower housing 1 and the upper housing 2 are stable. Grouped together.

In addition, the upper casing 2 is made of light-transmitting material. When the keyboard key structure 10 is equipped with light-emitting elements (not shown in the figure), the upper casing 2 can show the light source of the light-emitting elements (not shown in the figure).

The pressing shaft 3 is accommodated in the cavity s, the top end of the pressing shaft 3 passes through the through opening 23, and the pressing shaft 3 extends with one or more stoppers 31. Among them, the number of the stoppers 31 in this embodiment is two, and the stoppers 31 are arranged on both sides of the pressing shaft 3. When the pressing shaft 3 protrudes toward the through opening 23, the two stoppers 31 will be stopped by the top wall 21. Position to prevent the pressing shaft 3 from escaping from the cavity s from the through opening 23.

The spring 4 is accommodated in the cavity s and elastically supported between the lower housing 1 and the pressing shaft 2. Among them, the spring 4 in this embodiment is a coil spring, and the spring 4 is sleeved on the boss 13.

As shown in Figures 1 to 4, the use state of the creative keyboard key structure 10 is that the lower casing 1 is extended with two hooks 12, and the upper casing 2 is provided with two hollow card slots 24, each of the hooks 12 It is clamped in each hollow slot 24, so that the lower casing 1 and the upper casing 2 are firmly assembled up and down.

Thereby, the assembly structure of the lower casing 1 and the upper casing 2 is simple, and the hollow slot 24 of the upper casing 2 is easily demolded during the plastic injection molding process, so that the design size of the upper casing 2 can be reduced accordingly. The appearance design of the upper shell 2 is also relatively free and unrestricted, so that the keyboard key structure 10 has the advantages of freedom of appearance design of the upper shell 2, saving of finished products, and improved yield.

In summary, the keyboard key structure of this creation can indeed achieve the intended purpose of use, and solve the deficiencies of conventional knowledge. It is industrially usable, novel and progressive, and fully meets the requirements for patent applications. The application is filed in accordance with the Patent Law. Please check carefully and grant the patent for this case to protect the rights of the creator.
