Description

Technical Field

[0001] The utility model relates to the technical field of input devices, in particular to a key structure with adjustable stroke and an external input device. Background Art

[0002] Input devices with mechanical buttons have been widely used in daily life, such as keyboard input devices, game console controllers, and mechanical control buttons on certain devices. The overall structure of the above-mentioned devices is usually divided into an upper shell, a control panel, and a lower shell. Usually, the mechanical buttons match the slots arranged in the upper shell, so that the mechanical buttons can be embedded in the slots and connected to the control panel through elastic connecting shafts and other similar components. The HITBOX keyboard is a fighting game peripheral that combines the advantages of arcade joysticks and buttons to provide a more comfortable and efficient gaming experience. Its small size makes it convenient for players to use in different occasions. The design of the HITBOX focuses on ergonomics and usually adopts a split structure so that players can customize the configuration according to their preferences and needs. The plasticity of the appearance gives designers more room, and the wide customizability can meet the individual needs of different players, which is why it is loved by many players.

[0003] Despite its many advantages, the HITBOX keyboard's actuation travel is somewhat unsatisfactory for gamers. Different players have different control preferences: some prefer short travel to maximize gaming time, while others prefer longer travel for a more comfortable feel. Existing structures and technologies can only adapt to different players by replacing hot-swappable switches. However, due to the hot-swappable switch's inherent structure, varying specifications between manufacturers, and space constraints on the circuit board, players' options are limited.

The following is a detailed description of the stroke-adjustable key structure provided by the embodiment of the present invention.

[0040] In the embodiment of the present invention, multiple groups of slide grooves 22 can be set to different heights. The switching of the limiting protrusions 11 in different slide grooves 22 can limit the rebound height of the keycap 1, thereby adjusting the key stroke.

In order to facilitate switching between different strokes, the keycap 1 is cylindrical. After pressing the keycap, the limiting protrusion 11 is disengaged from the slide groove 22. By rotating the keycap 3, the limiting protrusion 11 is realigned with the new slide groove 22 to reset the keycap 3 to achieve stroke change. In order to accurately achieve stroke adjustment alignment, an alignment mark 100 is provided on the keycap 1, and a stroke mark 200 is provided on the assembly shell 2. For example, different colors of stroke marks 200 are used to represent strokes of different heights, and precise adjustment can be achieved by matching the alignment mark 100 (such as an arrow) to the stroke mark 200 of the corresponding color.

[0043] In the embodiment of the present utility model, Figure 9-10 As shown, in order to further reflect the advanced nature of the stroke-adjustable key structure provided by the present invention, an embodiment of the present invention also provides an external input device, including: a bottom shell and a plurality of the above-mentioned stroke-adjustable key structures, the bottom shell is provided with a circuit board, and the circuit board is provided with input contacts; a pressing column 10 is provided in the center of the keycap, one end of the pressing column 10 is fixedly connected to the inner side of the keycap 1, and when the keycap 1 is pressed, the other end of the pressing column 10 contacts the input contact to trigger signal transmission; after the assembly shell 2 and the bottom shell are equipped, the keycap 1 and the circuit board are confined in the accommodating space.

[0044] In summary, the stroke-adjustable key structure and external input device provided by the embodiments of the present invention cooperate with the radially extending limit protrusions on the side of the keycap and multiple groups of slide grooves with different extension heights set on the assembly shell, and switch the limit protrusions to move in different groups of the slide grooves to adjust the stroke of the keycap.
