[0002] Since the birth of electronic games, the design of game controllers has undergone several revolutions. From the initial simple buttons to modern complex multi-axis joysticks and multi-functional buttons, each evolution has greatly enriched the gaming experience. Traditional gaming buttons usually adopt mechanical structures, such as springs and contact pieces. When a player presses a button, the mechanical structure closes the circuit and sends a signal to the game console. With the progress of technology, especially the introduction of haptic feedback technology, the gaming experience has been further enhanced. Early haptic feedback was mainly achieved through vibration motors. When a player encounters a specific event in the game, the controller vibrates to simulate the feeling of collision or impact. However, this feedback method is relatively single and cannot provide delicate tactile changes, limiting the depth of immersion. Summary of the Utility Model

Detailed implementation manners

[0024] The following further describes the utility model of the present application in detail with reference to the drawings and specific embodiments. For the purpose of clearly and completely describing the technical solution, the following embodiments are selected for description; based on the content recorded in the present application, other embodiments obtained without creative labor fall within the protection scope of the present utility model.

[0025] In the following embodiments, it should be noted that the orientation or positional relationships such as "upper", "lower", "left", "right", "inner", "outer", "top / bottom" in the terms are all based on the orientation or positional relationships shown in the drawings, and are only for the convenience of clearly describing the present embodiments, rather than indicating or implying that the device or element referred to must have a specific orientation, so it cannot be understood as a limitation to the present application.

[0026] The following combines the attached Figures 1-4 to further describe the present application in detail,

[0027] Referring to Figure 1 , an embodiment of the present application discloses a game key with tactile feedback, including a PCB board 100, a partition 200 and a tactile unit.

[0028] The PCB board 100, as the core control component of the entire key, has a key matrix 110 for detecting user input. The key matrix 110 can identify the pressing state of the key and transmit the signal to the game system.

[0029] The partition 200 is mounted on the PCB board 100 by bolts, playing an isolation and support role, and has a mounting seat 210 for fixing the key body 300.

[0030] The tactile unit includes a key body 300, a linear motor 400, and a piezoelectric ceramic 500. The key body 300 is disposed within the mounting base 210 and directly interacts with the user. The linear motor 400 is installed within the key body 300 and can generate continuous or intermittent vibrations, such as the recoil of a weapon or the bumpiness of a vehicle, for simulating deep tactile sensations. The piezoelectric ceramic 500 is mounted on the key body 300 and has a rapid response, for providing instant tactile feedback, such as a click feeling or a sliding feeling.

[0031] Specifically, the positive and negative pins of the key body 300 and the pins of the linear motor 400 are electrically connected to the corresponding key matrix 110 respectively, ensuring the accuracy and real-time nature of signal transmission.

[0032] A game key with tactile feedback according to this embodiment, through the combined use of the linear motor 400 and the piezoelectric ceramic 500, enables the key to simulate various tactile sensations from slight vibrations to strong impacts, greatly enriching the gaming experience and providing multi-level tactile feedback; the precise tactile feedback can enable players to be more immersed in the game. Especially in game scenarios such as shooting and racing games, the simulated tactile sensations can significantly enhance the realism of the game, enhancing the authenticity and immersion of the game; the instant tactile feedback makes the operation more intuitive, and users can clearly perceive each of their actions, improving the feedback and precision of game control, and enhancing the intuitiveness and feedback of the operation.

[0033] Refer to Figure 1 and Figure 2 and Figure 3 , the key body 300 includes a keycap 310, a shaft body 320, a slider 330, and a connecting piece 340. The part of the keycap 310 that directly contacts the user's finger is designed in terms of its shape and size considering ergonomics to ensure a comfortable touch feeling. One end of the shaft body 320 is detachably connected to the keycap 310 for easy replacement and maintenance; the other end of the shaft body 320 is slidably installed within the mounting base 210 to ensure the smoothness and stability of the key action. The slider 330 is disposed between the shaft body 320 and the mounting base 210 and has an inclined opening 332. The connecting piece 340 is inserted into the mounting base 210 and includes a positive electrode piece 342 and a negative electrode piece 344. The positive electrode piece 342 is located within the opening 332, and the negative electrode piece 344 abuts against the inclined surfaces on both sides of the opening 332. When the keycap 310 is pressed down, the positive electrode piece 342 and the negative electrode piece 344 come into contact with each other. This design helps to guide the contact between the positive electrode piece 342 and the negative electrode piece 344 during the process of pressing down the keycap 310, ensuring the accurate triggering of the signal, forming a circuit closure, and sending a key signal to the PCB board 100.

[0034] With the above structure, when the user presses the keycap 310, the shaft 320 moves downward accordingly, driving the slider 330 to compress. At this time, the positive electrode sheet 342 is pushed forward within the opening 332 of the slider 330, and the negative electrode sheet 344 comes into contact with the positive electrode sheet 342 due to the effect of the inclined surface, thus completing the closing of the circuit. This process not only realizes the sending of key signals, but also provides instant and multi-level tactile feedback to the user through the coordinated work of the linear motor 400 and the piezoelectric ceramic 500, enhancing the feedback of operation and the authenticity of the gaming experience.

[0035] Through the precise cooperation between the keycap 310 and the shaft 320, as well as the ingenious design of the connecting piece 340, it is ensured that each key press can be triggered accurately without error and accompanied by instant tactile feedback, improving the accuracy and comfort of user operation. The detachable connection between the keycap 310 and the shaft 320 not only facilitates personalized customization, but also simplifies the maintenance and upgrade process, extends the product life. Combining the deep tactile simulation of the linear motor 400 and the instant tactile feedback of the piezoelectric ceramic 500, the keys of the present utility model can provide an all-round tactile experience from gentle touch to strong vibration, greatly enriching the immersion of game control.

[0036] Furthermore, one end of the shaft 320 located within the mounting seat 210 has a protrusion 322, and a first spring 324 is movably installed on the shaft 320. The two ends of the first spring 324 are respectively in contact with the inner bottom surface of the shaft 320 and the surface of the mounting seat 210.

[0037] The existence of the protrusion 322 is to better position the first spring 324 and ensure its stability and guiding property during the movement of the shaft 320. When the keycap 310 is pressed, the shaft 320 together with the protrusion 322 moves downward, compressing the first spring 324. The shape and position design of the protrusion 322 ensure the uniform force on the first spring 324, avoiding key jamming or unresponsive due to offset or tilt. When the user releases the keycap 310, the compressed first spring 324 quickly rebounds, pushing the shaft 320 and its upper structure upward to return to the initial position. This process not only ensures the quick reset of the key, but also provides clear tactile feedback to the user, enhancing the intuitiveness and feel of the operation. The elastic coefficient and pre-tightening force of the first spring 324 are carefully calibrated to generate appropriate resistance and rebound force during the pressing and resetting of the keycap 310, bringing a "paragraph feeling" similar to that of a mechanical keyboard to the user. This tactile feeling not only increases the satisfaction of key operation, but is also an indispensable part of game control. Especially in games that require precise operation, good tactile feeling can significantly improve the operation accuracy and reaction speed of players.

[0038] Refer to Figure 3The button body 300 further includes a restraining sleeve 350 , which is clamped on the mounting seat 210 and abuts against the top surface of the shaft body 320 , and has sliding grooves 352 on both sides, and the slider 330 is slidably installed between the sliding grooves 352 on both sides.

[0039] Through the above-mentioned structural setting, the constraint sleeve 350 is designed to be clamped on the mounting seat 210. This connection method not only ensures the stable positioning of the constraint sleeve 350, but also simplifies the assembly process, improves production efficiency and maintenance convenience. The top surface of the constraint sleeve 350 directly abuts against the top surface of the shaft body 320. This design helps to constrain the vertical movement of the shaft body 320 during the key operation, reduce lateral shaking, and ensure the accuracy and stability of the key action. The two sides of the constraint sleeve 350 are designed with slide grooves 352, and the slider 330 is slidably installed between these slide grooves 352. Such a structural arrangement ensures the smooth movement of the slider 330 during the key action, reduces friction and wear, and at the same time, the slide groove 352 also plays a guiding role, helping the slider 330 to move accurately along the predetermined path, avoiding the risk of deviating from the track, and the precise matching of the constraint sleeve 350 and the slide groove 352 provides a smooth and consistent trajectory for the overall movement of the key body 300, which is crucial for the normal operation of the tactile feedback mechanism. Regardless of whether the tactile feedback is provided by the linear motor 400 or the piezoelectric ceramic 500, a stable physical platform is required to ensure the accuracy and consistency of the feedback.

[0040] Reference Figure 4 , mounting plates 334 are slidably mounted on both sides of the inner wall of the slider 330, the mounting plate 334 has a slot 331, the shaft 320 has a connecting end 326, and the connecting end 326 is engaged in the slot 331;

[0041] Specifically, a second spring 336 is connected between the mounting plate 334 and the inner top surface of the slider 330 .

[0042] Through the above-mentioned structure, when the user presses the keycap 310, the shaft body 320 starts to move downward, and the connecting end 326 enters the slot 331, driving the mounting plate 334 and the slider 330 to move downward as a whole, and the second spring 336 is compressed. After releasing the keycap 310, the restoring force of the second spring 336 prompts the mounting plate 334 and the slider 330 to move upward, and the shaft body 320 is also reset, and the entire key system is restored to its original state, ready for the next operation. Through the coordinated work of the slider 330, the mounting plate 334 and the second spring 336, the key body 300 of the utility model not only ensures the high precision and stability of the key operation, but also optimizes the tactile feedback, providing the user with a more comfortable and intuitive operation experience. On the other hand, the connecting end 326 can be stuck in the slot 331 at different positions, changing the distance between it and the slider 330, thereby producing different tapping feelings to meet the needs of different customers.

[0043] Reference Figure 1 , a microcontroller 600 is electrically connected to the PCB board 100, and is used to control the vibration modes of the piezoelectric ceramic 500 and the linear motor 400.

[0044] With the above structure, when the user operates a button, the button matrix 110 detects the signal and transmits it to the microcontroller 600. The microcontroller 600 analyzes the characteristics of the signal, including the type, force, and duration of the button, as well as the information of the current game scene. Based on the above information, the microcontroller 600 generates control instructions for the piezoelectric ceramic 500 and the linear motor 400. These instructions contain parameters of the vibration mode, such as frequency, amplitude, and duration. The controller 600 sends the control instructions to the piezoelectric ceramic 500 and the linear motor 400, and the two perform corresponding vibrations according to the instructions, providing the user with immediate and variable tactile feedback. Based on the changes in the game scene and the user's operation, the microcontroller 600 can dynamically adjust the tactile feedback strategy. For example, in a racing game, the vibration mode can be adjusted according to the change in the material of the virtual road surface, or in a shooting game, the tactile simulation can be performed according to the different recoil characteristics of the weapon.
