Description

Trigger key structure and game handle Technical Field

[0001] The utility model relates to the technical field of game handles, in particular to a trigger key structure and a game handle. Background Art

[0002] With the continuous development of the electronic gaming industry, game controllers have become an important accessory for electronic games. By manipulating their buttons and other functions, users can control virtual characters in games. To meet the growing variety of games and personalized user needs, the functions of game controllers are constantly expanding. To enhance the user experience, some game controllers have designed trigger buttons on the game controllers. The force feedback of the trigger buttons enables interaction between game content and users, achieving a simulated real-life force feedback effect. Typically, the trigger button is the button used in the game to trigger rewards, open new plots, or aim. When used, it is pressed by gently pressing it, usually accompanied by vibration feedback. The degree of pressing will vary depending on the game scene and character.

[0003] The trigger buttons on existing game controllers typically utilize traditional compression springs or torsion springs in conjunction with a conventional rotor motor-driven gearbox. This allows the motor's shaft to deform the torsion spring, providing a damping effect for the user. The trigger buttons on existing game controllers typically need to be fixed to the controller's motherboard, where they are controlled. However, the layout of the gearbox for the existing trigger buttons consumes considerable space within the controller, making the trigger button structure inflexible when fixed to the controller's motherboard. This requires careful consideration of the component layout on the controller's motherboard.

[0034] In order to illustrate the technical solution of the present invention, a specific embodiment is provided below, in which only the parts related to the embodiment of the present invention are shown.

[0035] Embodiment 1: As shown in FIG1 , the present invention provides a trigger key structure, comprising a keycap module 1, a gear assembly 2, a control module 3, a Hall switch 4, and a fixing frame 5. The keycap module 1, the gear assembly 2, the control module 3, and the Hall switch 4 are all fixed on the fixing frame 5. The keycap module 1 is movably connected to the gear assembly 2, the Hall switch 4 is electrically connected to the control module 3, and the Hall switch 4 and the Hall magnet 14 of the keycap module 1 are arranged in correspondence with each other; the control module 3 is connected to the gear assembly 2, and the control module 3 is used to control the movement of the gear assembly 2. Specifically, the Hall switch 4 and the Hall magnet 14 of the keycap module 1 are arranged in correspondence with each other. When the user presses the keycap module 1, the Hall switch 4 can accurately identify the movement changes of the Hall magnet 14, and the Hall switch 4 transmits the obtained identification signal to the control module 3. At the same time, the control module 3 is electrically connected to the mainboard of the game controller, and the control module 3 also receives the processing signal sent by the mainboard. After receiving the identification signal of the Hall switch 4 and the processing signal of the mainboard, the control module 3 can control the movement of the gear assembly 2. The gear assembly 2 can drive the key cap module 1 to move in the opposite direction of the force applied to the user, thereby realizing the trigger key structure to give the user force feedback and realize the interaction between the user and the game.

[0036] By providing the control module 3 on the trigger key structure, a wired connection is established between the trigger key structure and the mainboard, making installation more flexible. The mainboard is also integrated, facilitating its layout. Furthermore, when the trigger key structure is assembled on a game controller, the Hall switch 4 is fixed to the mounting bracket 5, eliminating the need to consider the position of the Hall switch 4 during assembly. This improves the flexibility of assembling the trigger key structure on the game controller. Furthermore, the Hall switch 4 is fixed to the mounting bracket 5, facilitating alignment with the Hall magnet 14 of the keycap module 1. This eliminates the need to wait until the trigger key structure is assembled on the game controller before aligning the Hall switch 4 with the Hall magnet 14. This ensures precise alignment between the Hall switch 4 and the Hall magnet 14, improving the accuracy of Hall switch 4 detection.

[0037] The utility model arranges the Hall switch 4 on the fixing frame 5, and fixes the control module 3 connected to the gear assembly 2 on the fixing frame 5. The control module 3 is flexibly connected to the mainboard of the game controller through a signal line, so that the trigger key structure can be easily assembled on the game controller.

[0038] As an alternative embodiment, as shown in Figure 4, the control module 3 includes a control board 31, a connector 32, a foam pad 33, and an interface member 34. The control board 31 is mounted on a mounting frame 5. The interface member 34 is fixed to the first side of the control board 31, and the connector 32 is fixed to the second side of the control board 31. The connector 32 is press-fitted to the mounting frame 5 via the foam pad 33. The connector 32 is connected to the Hall switch 4 via a flexible board 41. Specifically, the control board 31 is fixed to one side of the mounting frame 5. The interface member 34 is fixed to the first side of the control board 31, facilitating electrical connection between the control board 31 and the main board, allowing the control board 31 to receive processing signals sent by the main board. The connector 32 is fixed to the second side of the control board 31 and positioned between the control board 31 and the mounting frame 5 to protect the connector 32. The connector 32 is press-fitted to the mounting frame 5 via the foam pad 33. The foam pad 33 has a certain degree of elasticity, protecting the connector 32 from vibration when the trigger mechanism is activated and from wear from the mounting frame 5. The connector 32 includes a first connector 321 and a second connector 322. The first connector 321 is connected to the mainboard through the interface part 34. The first connector 321 is used to receive the processing signal sent by the mainboard. The second connector 322 is connected to the Hall switch 4 through the flexible board 41. The second connector 322 is used to receive the identification signal detected by the Hall switch 4. The first connector 321 and the second connector 322 cooperate with each other to send control instructions to the gear assembly 2.

[0039] As an optional embodiment, as shown in Figure 2, the gear assembly 2 includes a driver 21, a motor gear 22, and a primary transmission gear 23. The driver 21 is fixed to the fixed frame 5, and one end of the driver 21 passes through the fixed frame 5 and is fixedly connected to the motor gear 22. The primary transmission gear 23 is fixed to the fixed frame 5 and meshes with the motor gear 22. Specifically, the driver 21 is fixed to one side of the fixed frame 5, preferably on the same side as the control board 31 on the fixed frame 5, to facilitate electrical connection between the driver 21 and the control board 31 via a signal line. After receiving a control command from the control module 3, the driver 21 is activated. The driver 21 rotates, driving the motor gear 22 fixed to one end of the driver 21 to rotate synchronously, causing the motor gear 22 to mesh with the primary transmission gear 23, thereby driving the primary transmission gear 23 to move synchronously. The primary transmission gear 23 is fixed to the fixed frame 5 via a rotating shaft. The primary transmission gear 23 has a clearance fit with the rotating shaft and can rotate around the rotating shaft. The primary transmission gear 23 comprises a large-diameter gear and a smaller-diameter gear, the diameter of which is smaller than that of the large-diameter gear. The smaller-diameter gear is fixed to the larger-diameter gear to form a double-layer gear, and the centers of the smaller and larger diameter gears coincide, enabling synchronous rotation. The motor gear 22 meshes with the larger-diameter gear of the primary transmission gear 23, while the brake member 13 of the keycap module 1 meshes with the smaller-diameter gear of the primary transmission gear 23. The driver 21 is preferably a motor.

[0040] As an optional embodiment, as shown in FIG2 , the keycap module 1 includes a trigger button 11, a trigger button bracket 12, and a brake member 13. The trigger button 11 is fixedly connected to the trigger button bracket 12, and the brake member 13 is movably connected to the trigger button bracket 12. Specifically, when the user presses the trigger button 11, the continuously transmitted pressure can drive the trigger button bracket 12 to rotate in the direction of the force applied by the user.

[0041] As an optional embodiment, as shown in Figures 2 and 7, the trigger key bracket 12 includes a first mounting groove 121 and a brake block 122. The Hall magnet 14 is arranged in the first mounting groove 121 and is arranged corresponding to the Hall switch 4. The first end of the brake member 13 is arranged corresponding to the brake block 122, and a rack 131 is provided on the second end of the brake member 13, and the rack 131 is engaged with the gear assembly 2. Specifically, the Hall magnet 14 and the first mounting groove 121 match each other, and the Hall magnet 14 can be firmly fixed in the first mounting groove 121. The Hall magnet 14 is arranged corresponding to the Hall switch 4 to ensure that the Hall switch 4 can accurately detect the movement changes of the Hall magnet 14. The first mounting groove 121 is provided on the first surface of the trigger key bracket 12. When the trigger key 11 is fixed to the trigger key bracket 12, it can cover the first mounting groove 121 and protect the Hall magnet 14. Brake block 122 is mounted on the second surface of trigger bracket 12. A second mounting slot is provided below brake block 122, facilitating the flexible connection of brake member 13 within the second mounting slot and aligning brake member 13 with gear assembly 2. When gear assembly 2 drives brake member 13, when the first end of brake member 13 abuts brake block 122, brake member 13 is braked, stopping its movement and transmitting force feedback to trigger bracket 12. In the case where gear assembly 2 includes drive member 21, motor gear 22, and primary transmission gear 23, brake member 13 meshes with the small-diameter gear of primary transmission gear 23 of gear assembly 2 via rack 131 on the second end of brake member 13.

[0042] When the user presses the trigger button 11, the control module 3 obtains the identification signal based on the movement of the Hall magnet 14 detected by the Hall switch 4, and the processing signal sent by the mainboard to the control module 3. The control module 3 sends a control instruction to the driving member 21, and the driving member 21 drives the motor gear 22 and the first-level transmission gear 23 to rotate, and continuously transmits the reverse force of the force applied by the user to the brake member 13 through the first-level transmission gear 23, so that the brake member 13 abuts against the trigger button bracket 12, and provides resistance to the trigger button bracket 12, thereby driving the vibration function of the trigger button 11.

[0043] As an optional embodiment, as shown in FIG3 , the fixing frame 5 includes a first bracket 51 and a second bracket 52. The first bracket 51 and the second bracket 52 are fixedly connected to form a receiving chamber for accommodating the gear assembly 2. The first bracket 51 includes a first mounting position 511, a second mounting position 512, and a third mounting position 513. The first mounting position 511 is used to fix the control module 3, the second mounting position 512 is used to fix the driver 21, and the third mounting position 513 is used to install the keycap module 1. Specifically, the first bracket 51 is used to support the gear assembly 2 and the control module 3. The first bracket 51 and the second bracket 52 are fixedly connected to form a receiving chamber for accommodating the brake member 13 of the keycap module 1, the motor gear 22, and the primary transmission gear 23 of the gear assembly 2, or the brake member 13 of the keycap module 1, the motor gear 22, the primary transmission gear 23, and the secondary transmission gear 24 of the gear assembly 2. The second bracket 52 cooperates with the first bracket 51 to protect the structures contained in the receiving chamber. The first mounting position 511 and the second mounting position 512 are preferably located on the same side of the fixing frame 5. The first mounting position 511 matches the control module 3, and when the control module 3 is fixed to the first mounting position 511, the mounting position of the control module 3 can be accurately determined. The second mounting position 512 matches the driving member 21 of the gear assembly 2, and when the driving member 21 is fixed to the second mounting position 512, the mounting position of the driving member 21 can be accurately determined. The third mounting position 513 is located at one end of the fixing frame 5, and the keycap module 1 is movably connected to the third mounting position 513, so that the keycap module 1 and the gear assembly 2 are arranged correspondingly.

[0044] As an optional embodiment, as shown in FIG5 , when the gear assembly 2 includes the driving member 21, the motor gear 22, and the primary transmission gear 23, the first bracket 51 further includes a first mounting hole 514 and a support bar 516. The first mounting hole 514 is used to fix the primary transmission gear 23, and the support bar 516 is used to support the brake member 13. Specifically, when the gear assembly 2 includes the driving member 21, the motor gear 22, and the primary transmission gear 23, the primary transmission gear 23 is fixed to the first mounting hole 514, and the support bar 516 is used to support the brake member 13 of the keycap module 1, so that the brake member 13 and the small-diameter gear of the primary transmission gear 23 are on the same plane, ensuring that the brake member 13 and the small-diameter gear of the primary transmission gear 23 are meshed.

[0045] As an optional embodiment, as shown in FIG5 , a trigger shaft 517 and a trigger torsion spring 518 are provided on the third mounting position 513.

Specifically, the trigger key bracket 12 and the brake member 13 are both sleeved on the trigger shaft 517 and have a clearance fit therewith. When the user presses the trigger key 11, the force applied by the user drives the trigger key bracket 12 and the brake member 13 to rotate about the trigger shaft 517, thereby actuating the trigger key 11. A trigger torsion spring 518 is sleeved on the trigger shaft 517 and is also engaged with the protrusion 519 of the third mounting position 513. After the gear assembly 2 is started, the gear assembly 2 can drive the brake member 13 to move in the opposite direction of the force applied to the user, and the brake member 13 abuts against the brake block 122 of the trigger key bracket 12 to transmit force feedback to the trigger key bracket 12 and the trigger key 11.

[0046] Embodiment 2: As shown in FIG6 , the present invention provides a trigger key structure, comprising a keycap module 1, a gear assembly 2, a control module 3, a Hall switch 4, and a fixing frame 5.

Specifically, the Hall switch 4 and the Hall magnet 14 of the keycap module 1 are arranged in correspondence with each other. When the user presses the keycap module 1, the Hall switch 4 can accurately identify the movement changes of the Hall magnet 14, and the Hall switch 4 transmits the obtained identification signal to the control module 3. At the same time, the control module 3 is electrically connected to the mainboard of the game controller, and the control module 3 also receives the processing signal sent by the mainboard. After receiving the identification signal of the Hall switch 4 and the processing signal of the mainboard, the control module 3 can control the movement of the gear assembly 2. The gear assembly 2 can drive the key cap module 1 to move in the opposite direction of the force applied to the user, thereby realizing the trigger key structure to give the user force feedback and realize the interaction between the user and the game.

[0047] More specifically, the control module 3 includes a control board 31, a connector 32, a foam pad 33, and an interface member 34.

The primary transmission gear 23 and the secondary transmission gear 24 are both fixed to the fixed frame 5, and the primary transmission gear 23 meshes with the motor gear 22 and the secondary transmission gear 24. Specifically, the driver 21 is fixed to one side of the fixed frame 5, preferably on the same side as the control board 31 on the fixed frame 5, to facilitate electrical connection between the driver 21 and the control board 31 via a signal line. After receiving the control command sent by the control module 3, the driving member 21 is started. The driving member 21 rotates, driving the motor gear 22 fixed to one end of the driving member 21 to rotate synchronously, so that the motor gear 22 engages with the primary transmission gear 23, thereby driving the primary transmission gear 23 to move synchronously. After the primary transmission gear 23 rotates, it can drive the secondary transmission gear 24 meshed with the primary transmission gear 23 to rotate synchronously. The primary transmission gear 23 and the secondary transmission gear 24 are respectively fixed to the fixed frame 5 by corresponding rotating shafts.

Both the primary transmission gear 23 and the secondary transmission gear 24 are configured as double-layer gears, each of which drives different components to rotate, so that different components that are movably connected to the same transmission gear do not affect each other.

[0050] As shown in Figure 8, more specifically, when the gear assembly 2 includes a driving member 21, a motor gear 22, a primary transmission gear 23 and a secondary transmission gear 24, the brake member 13 of the keycap module 1 is engaged with the small diameter gear of the secondary transmission gear 24 of the gear assembly 2 through the rack 131 on the second end of the brake member 13.
