AI Technical Summary
The existing game controller cross key design is because the external key cap is connected in one, and the keys rely on the shell to support it, resulting in the support point being unable to be in the physical center, which is prone to error touch and unclear feedback, which affects the user experience.
The inner bracket of the cross key cap is used to achieve elastic connection with the elastic bayonet. Combined with the ball seat bracket and the elastic silicone cap, a characteristic that can rotate freely around the center of the ball is designed, limiting the rotation of one of the shafts, retaining only the rotation freedom of the two shafts, and increasing the deformation ability to avoid interference from adjacent buttons.
It effectively avoids interference from adjacent buttons, increases the stroke of buttons, and intends to make up for the matching shape tolerance of the button system, ensures the consistency of the button feel, and improves the life and user experience of the buttons.

Abstract
Description
Technical Field
[0001] The utility model relates to the field of a cross key of a game controller, in particular to an improved cross key structure of a game controller. Background Art
[0002] Game controllers are usually designed with a cross-shaped button for directional functions. Since the shape of the cross button has an intuitive mapping with its function, it has become a standard feature of game controllers. However, the existing design concept of game controllers is usually composed of an external one-piece cross button cap and an internal silicone elastic pad, or directly only an external one-piece cross button cap and an internal touch switch. Since the external keycaps are connected in a cross shape and the buttons are supported by the shell, the support point cannot be made at the physical center of the cross button, but can only be biased to one side. When one of the keys in the cross button is pressed, the two connected keys will be linked due to the lever principle, resulting in false triggering. Because when one of the keys is pressed, the corresponding two adjacent keys are displaced, the reaction force of the key is provided by three keys at the same time, and the pace is inconsistent, causing the feedback of the key force to deviate from the feedback force curve of a single key, resulting in unclear key feedback and poor user experience. Utility Model Content
[0003] In order to overcome the problem that when using a game controller, because the external keycaps are connected in a cross shape and the keys are supported by the outer shell, the support point cannot be made at the physical center of the cross key, but can only be biased to one side, and the pace is inconsistent, causing the key force feedback to deviate from the feedback force curve of a single key, resulting in unclear key feedback and poor user experience.
[0004] The technical solution of the utility model is: an improved game controller cross key structure, including a cross key keycap; also includes a face shell, screws, a ball seat bracket, a cross keycap inner bracket, an elastic silicone cap, a cross groove bracket, a touch switch, a PCB circuit board, a fixing bolt, a quick-release buckle position, the surface center of the cross key cap is symmetrically provided with four groups of quick-release buckle positions, the bottom end of the cross key cap is provided with a face shell with a clamping groove, and the cross key cap is installed in the clamping groove of the face shell.
[0005] Preferably, an elastic snap-in is provided on the inner bracket of the cross keycap to realize elastic connection with the keycap, so that users can replace different types of cross key caps conveniently. The cross keycap is provided with a quick-release buckle position, so that users can buckle it off with their fingers conveniently. The elastic silicone cap is designed with a round head, which can better avoid interference caused by twisting of adjacent keys when pressing the keys.
[0006] Preferably, a ball socket bracket is provided inside the cross key cap, and four sets of screws are symmetrically threaded on the top of the ball socket bracket. A round bottom top column is provided in the middle position of the bottom end of the ball socket bracket, and the bottom end of the ball socket bracket is movably connected to the inner bracket of the cross key cap through screw threads.
[0007] Preferably, four groups of elastic snap-ons are symmetrically arranged at the top of the inner bracket of the cross keycap, and the elastic snap-ons and the cross keycap are elastically connected, and round head columns are symmetrically arranged at the bottom of the inner bracket of the cross keycap, a spherical joint socket is provided in the middle position inside the inner bracket of the cross keycap, and the round bottom top column is movably connected to the spherical joint socket.
[0008] Preferably, an elastic silicone cap is symmetrically arranged at the center of the bottom end of the inner bracket of the cross keycap, and the elastic silicone cap is sleeved on the outer side of the round head column. The bottom end of the inner bracket of the cross keycap is movably connected to a cross slot bracket with an installation groove, and the elastic silicone cap is inserted into the installation groove of the cross slot bracket.
[0009] Preferably, four sets of mounting plates are symmetrically arranged at the top center of the cross slot bracket, and the mounting plates are clamped to the outer side of the bracket inside the cross keycap, and four sets of screw columns are symmetrically arranged at the top center of the cross slot bracket, and the screws are threadedly connected in the screw columns.
[0010] Preferably, the bottom end of the cross slot bracket is movably connected to a PCB circuit board, four groups of touch switches are symmetrically welded to the center of the top end of the PCB circuit board, and the cross slot bracket is sleeved on the outside of the touch switch, and the face shell and the PCB circuit board are threadedly fixed by fixing bolts.
[0011] 1. The elastic bayonet is set with the cross key cap inner bracket to realize elastic connection with the key cap, which is convenient for users to replace different types of cross key caps. The cross key cap is set with a quick release buckle, which is convenient for users to buckle it with their fingers. The elastic silicone cap is designed with a round head, which better avoids the interference caused by the twisting of adjacent keys when pressing the keys;
[0012] 2. The ball joint can rotate freely around the center of the ball on three axes. The cross slot bracket can limit the rotation of one axis, leaving only two axes with rotational freedom, which just meets the working needs of the cross key. The elastic silicone cap with increased deformation capacity can avoid interference between two adjacent keys to the greatest extent, increase the stroke, and compensate for the matching shape and position tolerance of the key system, ensuring mass production and consistency of key feel.
[0013] 3. The cross keycap inner bracket limits the rotation within the limited space between the cross slot bracket and the surface shell, avoiding the touch switch and the elastic silicone cap from being damaged by forces exceeding their own, greatly increasing the life of the keys.
