[0002] In the prior art, traditional button designs are mainly used in keyboards, control panels and other fields. These buttons usually adopt mechanical or capacitive designs to meet the user's input needs through fixed positions and functions. This type of button has a simple structure and low cost, and has been widely used. However, the functions of traditional buttons are single and lack flexibility, especially when the usage scenarios are changing or the input function needs to be dynamically adjusted. Its limitations are more prominent. For example, in keyboard applications, the button layout is fixed, and users cannot flexibly adjust the button functions according to personal preferences or specific task requirements when using it.

[0019] Refer to the attached Figure 1 and 2 , this embodiment discloses a switch button with a display screen, which aims to solve the problems of fixed functions and insufficient display capabilities in existing button designs, so as to achieve a more flexible and efficient operating experience. The switch button of the present invention includes a shell 1, a shaft 2 inserted into the shell 1 and capable of sliding in a linear direction, a spring switch located in the shell 1 and cooperating with the shaft 2 to realize a trigger function, and a key cap 3 with a screen that is integrated with the shaft 2, wherein a display screen 4 is embedded in the top of the key cap 3 with a screen and protected by a transparent protective cover. The following content will explain in detail the specific implementation method of the present invention in combination with the structural characteristics, connection methods and working principles of each component.

[0020] The shell 1 of the button is made of high-strength ABS plastic. As the main supporting structure of the entire button device, it has good impact resistance and durability. At the same time, a pair of parallel slide grooves are provided inside the shell 1 to guide the movement of the shaft 2 in the linear direction. The design of the slide groove adopts precision processing to ensure that the shaft 2 is evenly stressed when sliding and avoid jamming. In addition, in order to ensure the automatic reset function after the shaft 2 is pressed, a reset spring 5 is also installed at the bottom of the shell 1. The material of the reset spring 5 is high-strength carbon steel, which has been optimized and has excellent elasticity and reset performance. Through the cooperation of the guide structure and the reset spring 5, the button can be accurately reset after each operation, which greatly improves the fluency and stability of use.

[0021] The shaft 2 is inserted into the slide groove of the housing 1, and precisely cooperates with the slide groove structure to realize the up and down sliding function. The material of the shaft 2 is high-strength stainless steel, which has excellent wear resistance and rust resistance, thereby ensuring the stability and service life of its structure under long-term and high-frequency pressing operations. The top of the shaft 2 and the keycap with screen 3 adopt an embedded buckle design, and the two are connected by a durable plastic buckle to ensure the close connection between the shaft 2 and the keycap 3 to avoid looseness due to long-term use. In addition, the buckle is designed as a built-in structure, which is aesthetically pleasing and dust-proof, and does not affect the user's feel during operation.

[0022] The design of the keycap with screen 3 is particularly important. A display screen 4 is embedded on the top of the keycap to display the function status of the key or the customized content. The display screen 4 is made of OLED material. Due to its high brightness, low power consumption and self-luminous characteristics, it ensures that the displayed content can be clearly presented under different light conditions. The display screen 4 is covered with a transparent protective cover made of polycarbonate (PC) material with high light transmittance and impact resistance. It can not only effectively protect the display screen 4 from external damage, but also does not affect the clarity of the display.

[0023] The display screen 4 is connected to the driver board through a flexible flat cable. The driver board is used to receive the driving signal from the contact 7 and control the display screen 4. The design of the driver board takes into account the spatial layout inside the key, adopts a compact PCB design, and optimizes the signal layout through multi-layer lines to ensure the stability and efficiency of the display signal and power transmission. The driver board is connected to the contacts 7 set at the bottom of the housing 1 through another flexible flat cable. These contacts 7 are used to realize the power supply and signal control of the display screen 4, ensuring the compatibility and applicability of the keys between different devices.

[0024] The shrapnel switch located inside the housing 1 is made of copper sheet, which has good conductivity and certain elasticity. It can quickly complete the circuit closure when the key is pressed, thereby realizing signal output. When the user presses the keycap with screen 3, the shaft rod 2 slides down, and the copper shrapnel contacts the contact 7, forming a circuit closure and outputting a trigger signal. In order to further optimize the user's operating experience, the shape of the shrapnel switch has undergone a precise arc design to ensure that the touch is consistent and the feedback is clear each time it is pressed. After the shrapnel switch is triggered, the shaft rod 2 is pushed back to the initial position by the reset spring 5, the key is reset, the circuit is disconnected, and a complete triggering process is completed.

[0025] Three magnetic blocks 6 arranged in a triangular shape are embedded at the bottom of the housing 1, with the N poles of two magnetic blocks 6 facing outward and the S pole of one magnetic block 6 facing outward. This design is used to match with an external mounting base or PCB board with corresponding magnetic blocks, and to achieve stable installation of the keys by magnetic fixation. The arrangement of the magnetic blocks 6 also has an anti-foolproof function, ensuring that the keys can automatically align with the installation position to avoid installation failures due to incorrect directions. This magnetic fixation method not only makes the keys quick to install and easy to disassemble, but also provides great convenience in modular application scenarios. For example, when the user needs to change the key layout, it can be directly disassembled by magnetic attraction, which greatly improves the maintenance and upgrade efficiency of the system.

[0026] In addition, to further enhance the installation stability of the key, a card block that matches the external mounting position is provided on the outside of the housing 1. When the key is installed on a keyboard or control device, the card block can fit tightly with the mounting position to provide additional mechanical support to prevent the key from loosening or shifting during use. The design of the card block takes into account the tolerance between the housing 1 and the device mounting position, and ensures the stability and consistency of the key installation through reasonable tolerance matching.

[0027] In actual application scenarios, the switch button with display screen of this embodiment can be widely used in various devices that require flexible adjustment and real-time display functions of buttons, such as smart devices, game controllers, and industrial control panels. For example, in a smart home control system, the button can be used to control lights, curtains and other equipment, and the current control status can be displayed in real time through the display screen 4 to enhance the user's interactive experience. In a game controller, the user can customize the content of the display screen 4 to display the specific functions of the button, such as skill icons, shortcut keys, etc., for easy and quick identification and operation, thereby obtaining a better gaming experience. In industrial control applications, the button can be assigned functions according to different operating tasks, and the real-time device status information can be displayed through the integrated display screen 4, so that operators can control and monitor the device status more conveniently and intuitively.

[0028] In summary, this embodiment realizes a modular switch key with display function through the housing 1, the shaft 2, the spring switch, the key cap with screen 3, the display screen 4, the reset spring 5, the magnetic block 6, the contact 7 and their organic combination. Through the reasonable design and optimization of the above-mentioned components, this embodiment not only overcomes the deficiencies of traditional keys in terms of function and flexibility, but also provides a more convenient installation method and a richer user interaction experience, with significant beneficial technical effects.
