Description

Technical Field

[0001] This utility model belongs to the field of keycap technology, and specifically relates to a metal keycap. Background Technology

[0002] Metal keycaps are heavier than plastic keycaps, giving them a substantial tactile feedback (a noticeable resistance, a solid feel, or a strong physical feedback during keystrokes), which satisfies the desire for a differentiated tactile experience, such as that of gamers. Since the connecting switches used to link the keycaps are typically made of plastic, if metal keycaps were made entirely of metal, the keycaps and switches could loosen over time, resulting in poor reliability and a shorter lifespan.

[0003] To address this, existing metal keycaps combine a metal outer shell and a plastic inner shell, with the plastic inner shell connecting to the connecting shaft. This makes both the keycap and the connecting shaft made of plastic, improving the reliability of their connection. For example, the external snap-on composite metal keycap provided by authorization notice number CN212848141U consists of a metal outer shell and a plastic inner shell. However, the plastic inner shell occupies a significant portion of the metal keycap's volume, resulting in a substantial reduction in the metal content. This severely impacts the solid, tactile feedback of the metal keycap and significantly diminishes the user experience. Utility Model Content

[0019] Metal keycaps consist of a metal keycap body and a plastic inner core. The metal keycap body is the main structure of the keycap and is made of metal. Compared to metal keycaps that separate the metal keycap body into a metal outer shell and a plastic inner shell, the metal content is higher, ensuring a better user experience. The plastic inner core is made of plastic and its connection with the keyboard's hinges ensures reliable connection.

[0020] The horizontal cross-sectional shape of the slot is non-circular. The side of the card block fits into the inner wall of the slot. On the one hand, since the installation position of the plastic core of the metal keycap needs to correspond to the connecting shaft on the keyboard, the non-circular slot makes it easy for the plastic core to be locked in the slot according to the preset position, which is convenient for assembly. On the other hand, the metal keycap body and the plastic core are connected by adhesive and limiting snap-fit ​​structure, which makes the connection reliable and improves the reliability, stability and durability of the connection between the metal keycap body and the plastic core.

[0028] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] A type of metal keycap, see Figures 1-4 The system includes a metal keycap body 10 and a plastic inner core 20. The inner top wall of the metal keycap body 10 has a slot 11, the horizontal cross-sectional shape of which is non-circular. The plastic inner core 20 includes an integrally formed locking block 21 and a connecting post 22, with the locking block 21 positioned on top of the connecting post 22. The locking block 21 is engaged within the slot 11, its side surface fitting against the inner wall of the slot 11, and the gap between the locking block 21 and the slot 11 is filled with adhesive 30.

[0030] The metal keycaps described above consist of a metal keycap body 10 and a plastic inner core 20. The metal keycap body 10 is the main structure of the keycap and is made of metal. Compared to metal keycaps that divide the metal keycap body 10 into a metal outer shell and a plastic inner shell, this type of keycap has a higher metal content, ensuring a better user experience. The plastic inner core 20 is made of plastic and its connection with the keyboard's hinge ensures reliable connection.

[0031] The horizontal cross-sectional shape of the slot 11 is non-circular, for example, rectangular. The side of the card block 21 is matched with the inner wall of the slot 11 for limiting. On the one hand, since the installation position of the plastic inner core 20 of the metal keycap needs to correspond to the connecting shaft on the keyboard, the non-circular slot 11 makes it easy for the plastic inner core 20 to be locked in the slot 11 according to the preset position, which is convenient for assembly. On the other hand, the metal keycap body 10 and the plastic inner core 20 are connected by the adhesive 30 and the limiting and locking structure, and the connection is reliable, which improves the reliability, stability and durability of the connection between the metal keycap body 10 and the plastic inner core 20.

[0032] In this embodiment, the top surface of the card block 21 is provided with two positioning posts 211, and the bottom of the card slot 11 is provided with two positioning grooves 12. The two positioning posts 211 are respectively positioned and engaged with the two positioning grooves 12. There is a glue-filling gap between the positioning posts 211 and the corresponding positioning grooves 12. This can improve the assembly accuracy, and the adhesive 30 can cover the mating surfaces of the two, increasing the bonding area and thus improving the connection reliability.

[0033] To further improve connection reliability, a filler groove 13 is provided at the bottom of the slot 11. Specifically, the filler groove 13 is I-shaped and located in the middle of the inner top wall of the metal keycap body 10. The filler groove 13 is filled with adhesive 30. By setting the filler groove 13, the bonding effect is further improved.

[0034] Furthermore, the bottom surface of the card block 21 is flush with the bottom of the slot 11, and the adhesive 30 is filled to the bottom surface of the card block 21 and the bottom of the slot 11. In this way, the adhesive 30 is filled from the bottom of the slot 11 and the positioning groove 12 and filling groove 13 inside the slot 11 to the inner top wall of the metal keycap body 10, forming a complete adhesive layer, making the connection more reliable.

[0035] In this embodiment, when bonding the plastic inner core 20, adhesive is first applied to the slot 11 of the metal keycap body 10, and then the plastic inner core 20 is inserted into the slot 11. To reduce the number of adhesive application steps and avoid air bubbles affecting the bonding effect, the combined volume of the positioning groove 12 and the filling groove 13 is configured such that after the block 21 is inserted into the slot 11, the adhesive 30 fills the bottom surface of the block 21 and the bottom of the slot 11. Thus, after the positioning groove 12 and the filling groove 13 are filled with adhesive, the plastic inner core 20 is directly inserted into the slot 11. At this time, the adhesive seeps out from the gap between the block 21 and the slot 11, and then fills the bottom surface of the block 21 and the bottom of the slot 11, forming a whole piece of adhesive 30.

[0036] To facilitate the engagement of the positioning post 211 and the positioning groove 12, the groove opening of the positioning groove 12 is radially expanded outward to form a flared portion 121.

[0037] In this embodiment, the top surface of the metal keycap body 10 is an arc-shaped concave surface 14 that is higher on both sides and lower in the middle. This shape is a conventional ergonomic design. Two positioning grooves 12 are correspondingly provided on both sides of the arc-shaped concave surface 14. Compared with the middle position, the metal keycap body 10 is thicker at this position, which can ensure the strength of the top surface of the metal keycap body 10 where the positioning grooves 12 are located.

[0038] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
