Description

Technical Field

[0001] This utility model relates to the field of game controller technology, and in particular to a keycap for the D-pad of a game controller. Background Technology

[0002] In existing game controller D-pad designs, a common practice is to extend a lever from the center of the bottom of the D-pad keycap, with the bottom end of the lever featuring a cross-shaped round or ball-shaped tip (e.g., ...). Figure 8 As shown in the image, the bottom of the D-pad keycap directly contacts the PCB board. This structure results in poor smoothness and fluidity of operation, mainly due to the following reasons: First, from a material perspective, the D-pad keycaps are usually made of plastic, while the PCB board in direct contact is generally made of rigid circuit board materials, such as epoxy resin fiberglass board. The two materials have significant differences in surface hardness and roughness; plastic is relatively soft and its surface is not smooth enough. During frequent oscillation operations, the friction between the two is hard friction, easily generating significant frictional force and hindering the smooth movement of the D-pad. For example, when players need to quickly switch directions in fast-paced games, this frictional force will cause the D-pad's response to lag noticeably, failing to keep up with the player's intentions. Second, uneven force distribution is also a key issue. Because the round or ball-shaped tip at the bottom of the lever only makes single-point or small-area contact with the PCB board, when the player applies force, the pressure is concentrated near the contact point. This not only exacerbates localized friction and wear, causing the material at the contact points to gradually wear down and deform, further increasing friction, but also easily leads to instability such as jamming and shifting during the D-pad's movement. For example, in some competitive games requiring precise micro-management, unstable movement of the D-pad may cause players to make mistakes and miss opportunities. Furthermore, there is a lack of an effective lubrication mechanism. It is evident that the existing D-pad keycaps directly contact the PCB board at the bottom, and the round / spherical design at the bottom of the lever makes it difficult to achieve ideal smoothness and fluidity during movement, requiring urgent improvement. Therefore, developing a D-pad keycap for a game controller has become a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0003] The present invention addresses the aforementioned shortcomings by providing a keycap for the D-pad of a game controller.

[0004] The above-mentioned objective of this utility model is achieved through the following technical solution: a cross keycap for a game controller, comprising a keycap body, a keycap body having four pressing parts in four directions, and a support rod at the bottom center of the keycap body, characterized in that: a joint bearing assembly is connected to the bottom of the support rod.

[0005] Further, the joint bearing assembly is a spherical sliding bearing assembly, which comprises an inner ring with an outer spherical surface and an outer ring with an inner spherical surface, a sliding layer is arranged between the inner spherical surface of the outer ring and the outer spherical surface of the inner ring, and the support rod is fixedly connected to the inner ring.

[0006] Further, the inner ring and the outer ring are made of metal.

[0007] Further, the outer ring is arranged in a fixed groove provided on the PCB of the gamepad, and the fixed groove is provided with an opening for preventing the PCB from interfering with the movement of the inner ring.

[0008] Further, the cross key cap of the gamepad further comprises a raised ring for preventing the PCB from interfering with the movement of the inner ring, and the raised ring is arranged in a fixed groove provided on the PCB of the gamepad.

[0009] Compared with the prior art, the utility model has the advantages of:

[0010] 1. Smooth operation: the innovative combination of the joint bearing assembly and the self-lubricating sliding layer greatly reduces the frictional resistance in the cross key operation process, and the player can achieve smooth and accurate direction switching by gently pushing the cross key, whether it is instantaneous turning in fast-paced competitive games or fine movement in fine operation games.

[0011] 2. Durability is enhanced: reducing component wear, prolonging the service life of the handle, reducing the frequency of replacing equipment for players, and saving costs.

[0012] 3. The stability of the structure is improved: when in use, the outer ring is arranged in a fixed groove on the PCB of the gamepad, so that the cross key remains stable under frequent operation and is not prone to problems such as loosening and displacement, further ensuring the reliability of game control.

[0013] 4. Upgrade game experience: smooth cross key operation allows players to focus more on game strategy and plot development, reducing frustration and mistakes caused by operation lag, fully immersing in the game world, improving the chances of winning, and enjoying the ultimate gaming experience.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings.

[0023] Example 1: As Figures 1 to 5 As shown, a cross-shaped keycap for a game controller includes a keycap body 1 with four pressing parts 2 on the keycap body 1. A support rod 3 is located at the center of the bottom of the keycap body 1, and a joint bearing assembly 4 is connected to the bottom of the support rod 3. The joint bearing assembly 4 is a spherical sliding bearing assembly, which includes an inner ring 401 with an outer spherical surface 403 and an outer ring 402 with an inner spherical surface 404. A sliding layer (not shown in the figure) is provided between the inner spherical surface 404 of the outer ring 402 and the outer spherical surface 403 of the inner ring 401. The sliding layer is made of a high molecular polymer or other advanced self-lubricating composite material, such as polytetrafluoroethylene (PTFE) based composite material, which has excellent self-lubricating properties and can spontaneously form an ultra-thin and uniform lubricating film on the friction surface, greatly reducing the coefficient of friction. The support rod 3 is fixedly connected to the inner ring 401. The inner ring 401 and the outer ring 402 are made of metal, preferably stainless steel. In use, the outer ring 402 is placed in a fixing slot 5 on the PCB board 8 of the game controller. The fixing slot 5 has an opening 6 to prevent motion interference between the PCB board 8 and the inner ring 401. At the same time, the PCB board 8 is provided with a button 9, and conductive adhesive 10 is provided between the keycap body 1 and the PCB board 8.

[0024] Example 2: As Figure 6 , Figure 7As shown, a cross key cap of a game handle comprises a cap body 1, four direction pressing parts 2 are arranged on the cap body 1, a supporting rod 3 is arranged at the bottom center of the cap body 1, a joint bearing assembly 4 is connected to the bottom of the supporting rod 3, the joint bearing assembly 4 is a spherical sliding bearing assembly, which comprises an inner ring 401 with an outer spherical surface and an outer ring 402 with an inner spherical surface, a sliding layer (not shown in the figure) is arranged between the inner spherical surface of the outer ring 402 and the outer spherical surface of the inner ring 401, the sliding layer is selected from high polymer or other advanced self-lubricating composite materials, such as polytetrafluoroethylene (PTFE) based composite material, which has excellent self-lubricating performance and can spontaneously form an ultra-thin and uniform lubricating film on the friction surface, greatly reducing the friction coefficient; the supporting rod 3 is fixedly connected to the inner ring 401; the inner ring 401 and the outer ring 402 are made of metal, preferably stainless steel. In order to prevent the PCB board 8 from interfering with the inner ring 401, the cross key cap of the game handle further comprises a raised ring 7, which is arranged in a fixed groove 5 arranged on the PCB board 8 of the game handle. At the same time, a key 9 is arranged on the PCB board 8, and a conductive adhesive 10 is arranged between the cap body 1 and the PCB board 8.

[0025] Due to the sliding layer between the inner ring 401 and the outer ring 402 of the joint bearing assembly having a very low friction coefficient and being able to continuously form a lubricating film during friction, the inner ring 401 can rotate at multiple angles relative to the outer ring 402 very smoothly, almost without resistance interference. This smooth rotation is quickly converted into precise displacement of the cross key on the plane, and the operation signal is transmitted to the mainboard through the wire, and the mainboard transmits the signal to the game console after processing, and the character or view angle in the game quickly and smoothly responds according to the control intention of the player's finger, realizing seamless game control experience, and allowing the player to enjoy the game pleasure brought by smooth operation.

[0026] Compared with the structure that the existing cross key cap and the PCB board are directly in contact, the joint bearing assembly introduced in the utility model can reduce the friction coefficient of the self-lubricating sliding layer in the bearing. In contrast, the traditional structure does not have a special lubrication means to reduce friction, so that the smoothness of operation of the cross key continuously decreases in the long-term and frequent use process, seriously affecting the game experience of the player.

[0027] The above only describes the preferred embodiments of the utility model and does not limit the utility model, and any modification, equivalent replacement and improvement made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
