Description

Technical Field

[0001] This utility model relates to the field of game controller technology, specifically to the structure of the D-pad of a game controller. Background Technology

[0002] A game controller, also known as a game gamepad, is the core control device for users to interact with game consoles, computers, or mobile devices. It converts user operations into electronic signals through various input devices such as buttons and joysticks. Among them, the D-pad is the most basic and frequently used directional input component on the controller. It is mainly responsible for controlling the movement of game characters, switching menu cursors, and triggering specific game moves. Its control accuracy and comfort directly determine the user's gaming experience.

[0003] Currently, most game controllers on the market use a one-piece thin-walled plastic structure or a simple pivot-type rocker design for their D-pads. In actual use, this easily leads to "key overlap," where when a user intends to trigger a single diagonal command, the controller incorrectly identifies two adjacent forward commands simultaneously, or the trigger direction is inconsistent with the expected direction. This fails to ensure that the force is accurately and independently transmitted to the target trigger point, severely impacting gameplay and competitive performance. Furthermore, traditional D-pads are mostly fixedly connected to the controller shell or internal structure, preventing users from changing keycaps to different shapes, heights, or surface textures according to personal preference or aesthetic needs, resulting in low personalization. Therefore, those skilled in the art provide a new D-pad structure for game controllers to solve the problems mentioned in the background. Utility Model Content

[0004] The purpose of this invention is to provide a D-pad structure for a game controller, thereby solving the problems mentioned in the background section of the prior art.

[0005] This utility model provides the following technical solution: a game controller cross button structure, including a PCB board for carrying and processing signals, four tactile switches arranged in an array are installed on one side of the PCB board, conductive silicone is provided on one side of the tactile switches, and a swing assembly for pressing the tactile switches is provided on one side of the conductive silicone. A protective faceplate is fixedly connected to one side of the PCB board, the swing assembly is disposed inside the faceplate, and a faceplate fastener bracket is provided on the side of the swing assembly away from the PCB board. A cross faceplate is installed on one side of the faceplate fastener bracket, and a snap-fit ​​assembly for fixing is installed on one side of the cross faceplate.

[0006] As a preferred embodiment of the above technical solution, the swing assembly includes four motion guide pins, which are arranged in a circular array on one side of the conductive silicone. The four motion guide pins are respectively positioned opposite the four tactile switches, and a positioning and fixing plate is sleeved between the four motion guide pins.

[0007] As a preferred embodiment of the above technical solution, a groove is provided on one side of the positioning and fixing plate, and a vertical swing rod and a horizontal swing rod are placed in the groove. A rotating opening is provided in the middle of the vertical swing rod, and the horizontal swing rod is rotatably connected to the inside of the rotating opening.

[0008] As a preferred embodiment of the above technical solution, the side of the lateral swing rod away from the PCB board has an internal threaded hole, the middle of the faceplate buckle bracket has a through opening, a screw slides in the through opening, the screw is threaded into the internal threaded hole, and multiple positioning posts are fixedly connected to one side of the positioning and fixing plate, all of which are set on one side of the PCB board.

[0009] As a preferred embodiment of the above technical solution, the snap-fit ​​assembly includes four fixing covers, which are arranged in a circular array. The four fixing covers are fixedly connected to one side of the cross face plate. Each of the four fixing covers has a trapezoidal snap-fit ​​block fixedly connected to its inner wall. The outer wall of the face plate buckle bone support has four snap-fit ​​slots, and the four trapezoidal snap-fit ​​blocks are respectively engaged with the four snap-fit ​​slots.

[0010] As a preferred embodiment of the above technical solution, two soft rubber rivets are fixedly connected to one side of the conductive silicone, the two soft rubber rivets penetrate the PCB board, a positioning hole is provided on the PCB board, and a positioning block is fixedly connected to one side of the faceplate, the positioning block and the positioning hole are matched.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This device utilizes a swing assembly consisting of a horizontal and a vertical swing rod within a groove in a positioning plate. Combined with four motion guide pins driven at their ends and constrained by the positioning plate, it can precisely and evenly transmit pressing pressure from different directions to the conductive silicone and the tactile switch below. This not only effectively solves the "key overlap" problem of traditional cross keys, achieving accurate recognition and consistent triggering of eight-directional operation commands, but also provides a comfortable tactile feedback from the conductive silicone. Furthermore, the cross-shaped faceplate, fixed by the snap-fit ​​assembly, is easy to disassemble and replace, enhancing the product's customizability and maintenance convenience.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Please see Figures 1-6 This utility model provides a technical solution: a cross-shaped button structure for a game controller, including a PCB board 1 for carrying and processing signals, four tactile switches 2 arranged in an array on one side of the PCB board 1, conductive silicone 3 on one side of the tactile switches 2, a swing assembly 4 for pressing the tactile switches 2 on one side of the conductive silicone 3, a protective faceplate 5 fixedly connected to one side of the PCB board 1, the swing assembly 4 being disposed inside the faceplate 5, a faceplate bracket 6 being disposed on the side of the swing assembly 4 away from the PCB board 1, a cross-shaped faceplate 7 being installed on one side of the faceplate bracket 6, and a locking assembly 8 for fixing being installed on one side of the cross-shaped faceplate 7.

[0023] Furthermore, when the user presses the cross faceplate 7, the operating force is transmitted to the faceplate buckle support 6 through the snap-fit ​​component 8, which in turn drives the swing component 4 below to produce directional swing. The swing motion of the swing component 4 compresses the conductive silicone 3, causing it to deform and accumulate rebound force. At the same time, this pressure penetrates the conductive silicone 3 and accurately triggers the tactile switch 2 at the corresponding position. The electrical signal generated by the tactile switch 2 is carried and processed by the PCB board 1, thereby completing a command input. Throughout the process, the faceplate 5 provides structural support and external protection for the interior, the conductive silicone 3 effectively optimizes the button feel and provides a soft rebound, the swing component 4 ensures accurate recognition and triggering of multi-directional operations, and the snap-fit ​​component 8 enables convenient disassembly and assembly of the cross faceplate 7, improving the product's customizability and maintenance convenience.

[0024] It should be noted that the internal tactile switch 2 has modular features and can be flexibly replaced with conductive rubber buttons or electronic tactile switches 2 as needed, enhancing the product's adaptability and design flexibility.

[0025] As one implementation method in this embodiment, please refer to Figures 3-5 As shown, the swing assembly 4 includes four motion guide pins 401, which are arranged in a ring array on one side of the conductive silicone 3. The four motion guide pins 401 are respectively facing the four tactile switches 2, and a positioning and fixing plate 402 is sleeved between the four motion guide pins 401.

[0026] A groove 403 is provided on one side of the positioning and fixing plate 402. A vertical swing rod 404 and a horizontal swing rod 405 are placed in the groove 403. A rotating opening 406 is provided in the middle of the vertical swing rod 404. The horizontal swing rod 405 is rotatably connected to the inside of the rotating opening 406.

[0027] The horizontal swing rod 405 has an internal threaded hole 407 on the side away from the PCB board 1. The faceplate buckle bracket 6 has a through hole 408 in the middle. A screw 409 slides in the through hole 408 and is threaded into the internal threaded hole 407. Multiple positioning posts 410 are fixedly connected to one side of the positioning and fixing plate 402. All positioning posts 410 are set on one side of the PCB board 1.

[0028] Furthermore, when the faceplate buckle bone support 6 is pressed, the screw 409 in its through-hole 408 transmits force to the internal threaded hole 407 of the threaded transverse swing rod 405, driving the transverse swing rod 405. The transverse swing rod 405 transmits motion through its rotational connection with the rotation port 406 of the vertical swing rod 404, causing the vertical swing rod 404 and the transverse swing rod 405 to generate a compound swing in a specific direction within the groove 403 of the positioning and fixing plate 402. The ends of the vertical swing rod 404 and the transverse swing rod 405 then press against the corresponding motion guide pins 401. These motion guide pins 401... Constrained by the commonly fitted positioning and fixing plate 402, the swing is converted into precise vertical downward pressure, which ultimately triggers the tactile switch 2. The entire swing assembly 4 is abutted against the PCB board 1 by multiple positioning posts 410 on one side of the positioning and fixing plate 402, ensuring the stability of the structure. The combined movement of the vertical swing rod 404 and the horizontal swing rod 405 realizes the accurate identification and force transmission of operation in multiple directions. The cooperation between the motion guide pin 401 and the positioning and fixing plate 402 ensures the accurate conversion of the pressing direction, while the rigid connection between the screw 409 and the internal threaded hole 407 provides a direct and solid driving point.

[0029] As one implementation method in this embodiment, please refer to Figure 3 and Figure 6 As shown, the snap-fit ​​assembly 8 includes four fixing covers 801, which are arranged in a circular array. The four fixing covers 801 are fixedly connected to one side of the cross face plate 7. Trapezoidal snap-fit ​​blocks 802 are fixedly connected to the inner walls of the four fixing covers 801. The outer wall of the face plate buckle bone support 6 is provided with four snap-fit ​​slots 803. The four trapezoidal snap-fit ​​blocks 802 are respectively engaged with the four snap-fit ​​slots 803.

[0030] Furthermore, using four fixed covers 801 arranged in a ring array as the installation base, the trapezoidal locking blocks 802 on the inner wall of the fixed cover 801 utilize their own inclined guiding action to elastically deform and slide into the corresponding locking groove 803 on the outer wall of the faceplate bracket 6 when they align. Subsequently, the material rebound causes the vertical surface of the trapezoidal locking block 802 to form a firm mechanical interlock with the inner wall of the locking groove 803, thereby achieving rapid fixing of the cross faceplate 7. This greatly improves the efficiency of replacing the cross faceplate 7 for personalized customization or maintenance and cleaning. At the same time, the trapezoidal structure ensures high reliability of the connection under vibration and frequent use, effectively preventing loosening.

[0031] As one implementation method in this embodiment, please refer to Figures 2-4 As shown, two soft rubber rivets 9 are fixedly connected to one side of the conductive silicone 3. The two soft rubber rivets 9 penetrate the PCB board 1. The PCB board 1 has positioning holes 10. A positioning block 11 is fixedly connected to one side of the faceplate 5. The positioning block 11 matches the positioning hole 10.

[0032] Furthermore, during assembly, two soft rubber rivets 9 are precisely inserted into and penetrate the PCB board 1. The interference fit between the soft rubber rivets 9 and the hole wall forms a riveting structure, thereby firmly binding the conductive silicone 3 to a specific position on the PCB board 1. This effectively prevents it from shifting or falling off under frequent pressing or vibration, ensuring the consistency of the button's tactile feel and the reliability of triggering. The positioning holes 10 and positioning blocks 11 facilitate the user's installation of the faceplate 5, making the faceplate 5 stably positioned on the designated position on the PCB board 1, which is convenient for the user to fix the faceplate 5 later.

[0033] Working principle: When the user presses the detachable cross faceplate 7, the force is transmitted through the faceplate buckle bracket 6 to the intersection center of the horizontal swing rod 405 and the vertical swing rod 404. The horizontal swing rod 405 and the vertical swing rod 404 are rotatably connected through the rotating port 406 and are housed in the groove 403 of the positioning and fixing plate 402. Depending on the pressing direction, the horizontal swing rod 405 and the vertical swing rod 404 produce specific motion combinations. For example, when the user presses upward in a single direction, the force acts on the upper end of the vertical swing rod 404, causing it to sink around the fulcrum of the rotating port 406, and the end presses against the corresponding motion guide pin 401, while the horizontal swing rod 405 remains stationary. When the user presses diagonally, such as to the upper left, the force acts simultaneously on the upper end of the vertical swing rod 404 and the left end of the horizontal swing rod 405, causing the horizontal swing rod 405 and the vertical swing rod 404 to sink synchronously, pressing against the upper end respectively. The motion guide pin 401 on the left is constrained by the hole position of the positioning plate 402, which converts the tilting motion of the horizontal swing rod 405 and the vertical swing rod 404 into vertical downward pressure. The motion guide pin 401 presses the conductive silicone 3 and triggers the tactile switch 2. Through the independent or combined motion of the horizontal swing rod 405 and the vertical swing rod 404, combined with the vertical guiding effect of the motion guide pin 401, the accurate identification and triggering of single-direction and diagonal operation is realized, which fundamentally solves the "keying error" problem and ensures the consistency of the feel of all-round operation. When the user releases the cross face plate 7, the elasticity of the tactile switch 2 and the deformation recovery force of the conductive silicone 3 work together to push the horizontal swing rod 405 and the vertical swing rod 404 upward through the motion guide pin 401, and finally reset the entire operating mechanism to a horizontal neutral state, ready for the next input.

[0034] Four fixed covers 801 arranged in a ring array serve as the mounting base for the cross face plate 7. The trapezoidal locking blocks 802 on the inner wall of the fixed cover 801 utilize their own inclined guiding action to elastically deform and slide into the corresponding locking groove 803 on the outer wall of the cross face plate 7 when they align. Subsequently, the material rebound causes the vertical surface of the trapezoidal locking block 802 to form a firm mechanical interlock with the inner wall of the locking groove 803, thereby achieving rapid fixing of the cross face plate 7. This greatly improves the efficiency of replacing the cross face plate 7 for personalized customization or maintenance and cleaning. At the same time, the trapezoidal structure ensures high reliability of the connection under vibration and frequent use, effectively preventing loosening.

[0035] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
