They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] The following is in conjunction with the appendix Figure 1-6 The present invention will be further described below.

[0026] To address the problems existing in the background technology, this application proposes the following technical solution: It includes a lower housing 1, an upper housing 2 mounted on the lower housing 1, a display screen 3 fixedly mounted on the upper housing 2, a knob 4 on one side of the display screen 3, the knob 4 being rotatably mounted on the display screen 3, a circuit board 6 fixedly mounted below the upper housing 2, a pin shaft 9 positioned below the circuit board 6, a PCB board 5 fixedly connected to the lower housing 1, and contacts 11 fixedly mounted on the PCB board 5, the contacts 11 being compatible with the pin shaft 9.

[0027] The upper housing 2 is detachably connected to the lower housing 1. The circuit board 6 is electrically connected to the display screen 3, and the display screen 3 is electrically connected to the knob 4. The knob 4 can be used to adjust the lighting, performance parameters, etc., and the adjustment results can be displayed on the display screen 3, improving the user experience. After the upper housing 2 is connected to the lower housing 1, the pin shaft 9 contacts the contact point 11. The connection between the pin shaft 9 and the contact point 11 realizes the electrical connection between the PCB board 5 and the display screen 3. When the upper housing 2 is separated from the lower housing 1, the pin shaft 9 and the contact point 11 are disconnected. This avoids the traditional ribbon cable affecting the disassembly and assembly of the keyboard. The operation is simple and the keyboard can be used immediately after installation. At the same time, it avoids damage to the ribbon cable caused by disassembly and assembly of the keyboard, which would affect the normal use of the keyboard, thereby improving the service life of the keyboard.

[0028] To further explain, a needle body 7 is fixedly installed under the circuit board 6, and a groove 8 is provided in the needle body 7, with the needle shaft 9 slidably installed in the groove 8.

[0029] The needle body 7 provides mounting conditions for the needle shaft 9, allowing the needle shaft 9 to slide on the needle body 7, and the connection between the needle shaft 9 and the circuit board 6 is achieved through the needle body 7.

[0030] Furthermore, a spring 10 is fixedly installed in the slide groove 8, and one end of the spring 10 is fixedly connected to the needle shaft 9.

[0031] When the upper housing 2 is installed on the lower housing 1, the upper housing 2 drives the needle body 7 to move via the circuit board 6. The needle body 7 drives the needle shaft 9 to move via the spring 10. The needle shaft 9 contacts and squeezes the contact point 11 on the PCB board 5, causing the needle shaft 9 to move inward into the needle body 7. The spring 10 is compressed and deformed. The compressed spring 10 pushes the needle shaft 9 in the opposite direction to restore its initial state, so that the needle shaft 9 always has a tendency to move towards the contact point 11. This ensures long-term reliable contact between the needle shaft 9 and the contact point 11, reduces the risk of poor contact or short circuit, and improves the stability of the keyboard during use. The display screen 3, knob 4, PCB board 5 and circuit board 6 are all existing mature technologies, and their related circuit connections and control principles will not be described in detail in this application.

[0032] Furthermore, an anti-detachment plate 16 is slidably installed in the slide groove 8, and the anti-detachment plate 16 is fixedly connected to one end of the needle shaft 9.

[0033] One end of the spring 10 is fixedly connected to one end of the needle shaft 9 via the anti-detachment plate 16. The anti-detachment plate 16 guides and limits the movement of the needle shaft 9, improves the stability of the needle shaft 9 when sliding in the slide groove 8, ensures stable contact between the needle shaft 9 and the contact point 11, and prevents the needle shaft 9 from accidentally falling out of the needle body 7.

[0034] To further explain, a ball-bearing head 12 is fixedly installed on the lower part of the upper housing 2, and an installation groove 13 is provided on the lower housing 1. A base plate 14 is fixedly connected in the installation groove 13, and a slot 15 is provided on the base plate 14, which is adapted to the ball-bearing head 12.

[0035] A ball is provided in the base plate 14, and an elastic element is installed inside the base plate 14. The elastic element presses the ball against the edge of the opening of the slot 15, so that part of the ball protrudes from the shell. When the upper shell 2 is connected to the lower shell 1, the ball head 12 is inserted into the slot 15. The ball head 12 pushes the ball out of the slot 15. Under the action of the elastic element, the ball is locked into the positioning part of the ball head 12, forming a snap-fit ​​fixation. The upper shell 2 and the lower shell 1 are connected together through the ball head 12 and the base plate 14. When it is necessary to remove the upper shell 2 from the lower shell 1, the user applies a certain external force. The ball head 12 causes the ball to compress the elastic element and move into the base plate 14, disengaging from the positioning part of the ball head 12. This realizes the quick connection and separation of the lower shell 1 and the upper shell 2 without the need for tools. The operation is simple and convenient.

[0036] For specific operation and use, please refer to the following: When the upper housing 2 is installed on the lower housing 1, the upper housing 2 drives the needle body 7 to move through the circuit board 6. The needle body 7 drives the needle shaft 9 to move through the spring 10. The needle shaft 9 contacts and squeezes the contact 11 on the PCB board 5, causing the needle shaft 9 to move inward into the needle body 7. The spring 10 is compressed and deformed. The compressed spring 10 pushes the needle shaft 9 in the opposite direction to restore its initial state, so that the needle shaft 9 is always in contact with the contact 11. The electrical connection between the PCB board 5 and the circuit board 6 is achieved through the contact 11, the needle shaft 9 and the needle body 7. When disassembling the keyboard, compared with the traditional keyboard, the upper housing 2 can be directly separated from the lower housing 1 without worrying about damaging the electrical connection between electronic components.
