Technical Field
[0001] This utility model relates to game controllers, and more particularly to a game controller housing assembly. Background Technology
[0002] In the gaming industry, gamepads are essential tools for players to interact with games. Currently, most gamepads on the market have back buttons on the back of their casings. The original design of these back buttons was to provide players with more control options to meet the operational needs of some complex games. However, in some game scenarios where back buttons are unnecessary, their presence has negative effects. Because the back buttons protrude from the casing surface, they may cause unnecessary friction or pressure between the player's hand and the controller, affecting the feel and causing discomfort during gameplay. Furthermore, accidental activation of the back buttons can lead to errors in gameplay, thus reducing the gaming experience. Therefore, developing a gamepad casing component that can flexibly adjust the use of back buttons according to game requirements is of significant practical importance. Utility Model Content

[0018] The present invention will now be described in further detail with reference to the accompanying drawings.
[0019] Example 1: Application of a flexible game controller component with magnetic connection:
[0020] like Figure 1 , Figure 2 and Figure 3 As shown, a game controller housing assembly includes a front shell 1, a fixed bottom shell 2, a secondary shell 3 without back buttons, and a secondary shell 4 with back buttons. The fixed bottom shell 2 and the front shell 1 are connected by clips or screws, ensuring the stability of the main housing and allowing it to withstand certain external forces without easily loosening. There is one secondary shell 3 without back buttons and one secondary shell 4 with back buttons on each side, mounted on the back of the grip area of the game controller. Both the secondary shell 3 without back buttons and the secondary shell 4 with back buttons are connected to the front shell 1 magnetically, with the magnetic connection area evenly distributed to ensure the stability and accuracy of the connection.
[0021] The sub-shell 4 with back buttons has a back button keycap mounting port 5, and a corresponding number of back button keycaps 6 are installed in the back button keycap mounting port 5 (in this embodiment, one back button keycap mounting port 5 is provided on each sub-shell 4 with back buttons, and a back button keycap 6 is installed; in other embodiments, two or more back button keycap mounting ports 5 can be provided on each sub-shell 4 with back buttons, and a corresponding number of back button keycaps 6 can be installed). The position of the back button keycaps 6 corresponds to the position of the back button 7 installed on the main control circuit board 8 inside the controller shell. When the sub-shell 4 with back buttons is connected to the front shell 1, the back button keycaps 6 can achieve good contact and signal transmission with the back button on the main control circuit board 8, ensuring the normal use of the back button function. The material of the back button keycaps 6 has a good tactile feel, and the surface texture design conforms to ergonomics, allowing players to operate more comfortably and accurately.
[0022] When players need to use back buttons in games, such as action games like the Call of Duty series, where rapid weapon switching and tactical action triggering are required, back buttons can significantly improve operational efficiency. In this case, the player selects the back button sub-shell 4 from the options of a non-back button sub-shell 3 and a back button sub-shell 4. By bringing the back button sub-shell 4 close to the front shell 1, under the influence of magnetism, the back button sub-shell 4 automatically and accurately aligns with and tightly connects to the front shell 1 (e.g., ...). Figure 2 The magnetic connection is not only convenient, eliminating the need for players to perform complex alignment and installation operations, but the magnetic attraction also ensures the stability of the connection. During gameplay, even if the controller is subjected to some shaking or impact, the secondary shell 4 with back buttons will not easily fall off.
[0023] When playing games that don't require the back button function, such as some casual puzzle games like Monument Valley, players can simply gently remove the back button sub-shell 4 from the front cover 1. Then, bring the back buttonless sub-shell 3 close to the front cover 1; under the same magnetic force, the back buttonless sub-shell 3 will connect to the front cover 1 (e.g., ...). Figure 3 The back-button-less sub-shell 3 has no keycaps and a smooth surface, making the grip more natural and comfortable for players without the interference of back buttons. The back-button-less sub-shell 3 also connects stably to the front shell 1 via magnetic attachment, ensuring it won't loosen or shift during gameplay and providing a superior gaming experience.
[0024] Example 2: Application of game controller components in snap-fit connection mode:
[0025] Reference Figure 1 , Figure 2 and Figure 3 As shown, a game controller housing assembly includes a front shell 1, a fixed bottom shell 2, a secondary shell 3 without back buttons, and a secondary shell 4 with back buttons. The fixed bottom shell 2 and the front shell 1 are connected by clips or screws. There is one secondary shell 3 without back buttons and one secondary shell 4 with back buttons, mounted on the back of the grip area of the game controller. Both the secondary shell 3 without back buttons and the secondary shell 4 with back buttons are connected to the front shell 1 by screws or clips (not shown in the figure). The secondary shell 4 with back buttons has a back button cap mounting port 5 and mounts a back button cap 6. The position of the back button cap 6 corresponds to the mounting position of the back button 7 on the main control circuit board 8 inside the controller housing.
[0026] When playing games that require back buttons, players can choose the back button sub-shell 4 from the options of the non-back button sub-shell 3 and the back button sub-shell 4. Align it with the snap-fit position on the front shell 1 and press gently to complete the connection. The snap-fit connection is simple and players can quickly install it without the need for any other tools.
[0027] When playing games that do not require back keys, remove the secondary shell 4 with back keys from the front shell 1 and install the secondary shell 3 without back keys, aligning it with the snap-fit position on the front shell 1. The secondary shell 3 without back keys has a smooth surface and no keycaps. It is also securely connected to the front shell 1 using a snap-fit mechanism, preventing it from falling off during use.
[0028] Example 3: Application of game controllers with screw connections to ensure stability:
[0029] like Figure 4 , Figure 5 and Figure 6As shown, a game controller housing assembly comprises a front shell 1, a fixed bottom shell 2, a secondary shell 3 without back buttons, and a secondary shell 4 with back buttons. The fixed bottom shell 2 and the front shell 1 are connected by clips or screws, and the secondary shell 3 without back buttons and the secondary shell 4 with back buttons are both connected to the front shell 1 by screws. The secondary shell 4 with back buttons has two back button cap mounting holes 5, and two back button caps 6 are installed on it. The back button caps 6 correspond to the back buttons 7 on the main control circuit board 8 inside the controller housing.
[0030] When participating in competitive games that demand high stability, players should select the secondary shell 4 with back buttons, align it with the front shell 1, and secure it with screws (e.g., Figure 5 The screw connection provides strong connection strength, ensuring that the secondary housing 4 with back buttons will not loosen during intense gaming operations.
[0031] When the back button function is not needed, the player uses a screwdriver to unscrew the screws on the secondary shell 4 with back buttons, remove it, and replace it with the secondary shell 3 without back buttons. Similarly, the player uses screws to fix the secondary shell 3 without back buttons onto the front shell 1 (e.g., ...). Figure 6 The secondary shell 3, without back keys, has a flat surface and no keycaps. It is connected with screws to achieve a tight fixation with the front shell 1, meeting the usage needs of players in different scenarios.
