[0002] The existing equipment main control computer needs to be connected to a keyboard or key panel for command input. The existing key panel is usually fixed outside the host box, which has the following disadvantages: 1. It takes up external space; 2. Since the key panel is set outside, people may accidentally touch the key panel, thereby inputting wrong commands, which will affect the normal operation of the equipment. Summary of the invention
[0003] The purpose of the present invention is to solve the problem that the key panel of the existing device main control computer is set on the outside of the main box. This setting method not only occupies external space, but also makes it easy for people to accidentally touch the key panel, thereby entering wrong instructions and affecting the normal operation of the equipment. A hidden key panel structure is provided to effectively solve the above problem.
[0004] The objective of the present invention is achieved through the following technical scheme: a hidden key panel structure, comprising a main case and a key panel, wherein a key tray is slidably connected to the main case, a receiving cavity for receiving the key tray is provided in the main case, and the key panel is arranged above the key tray; a ball head is provided at the lower end of the key tray, and an elastic claw group corresponding to the ball head is provided on the main case, wherein the elastic claw group consists of two elastic claws arranged opposite to each other, and the elastic claws are in an arc shape.
[0005] In the present invention, when the key panel needs to be used, the key tray can be pulled outward, so that the key panel can be operated, thereby inputting corresponding instructions to the main control computer; after use, the key tray is pushed into the main box, so that the key panel is hidden in the main box. When the key tray is pushed to the bottom, the ball head set on the key tray just extends between the two elastic claws, and the two elastic claws hold the ball head, so that the key tray will not slide out easily. The advantages of the above structure are: 1. When the key panel is not in use, the key panel is hidden in the main box and will not occupy external space; 2. When the key panel is not in use, since the key panel is hidden in the main box, the surface of the key panel is not easy to fall dust, and a large amount of dust will not accumulate; 3. When the key panel is not in use, since the key panel is hidden in the main box, outsiders will not accidentally touch the key panel, thereby not inputting wrong instructions, ensuring the normal operation of the equipment.
[0006] Preferably, the elastic claw is provided with an introduction slope at one end close to the ball head. The end of the elastic claw is provided with an introduction slope, and under the effect of the introduction slope, the ball head can enter between the two elastic claws more easily.
[0007] Preferably, the mainframe is provided with a guide rail, the key tray is provided with a slider matching the guide rail, and the slider is slidably connected to the guide rail. Through the cooperation between the guide rail and the slider, a sliding connection is formed between the key tray and the mainframe.
[0008] Preferably, a fixing block is connected to the main chassis, and the elastic claws are arranged on the fixing block, and the elastic claws are integrally formed with the fixing block.
[0009] Preferably, the fixing block and the elastic claws are both made of plastic.

In the present invention, the roller is sunk to a certain depth in the surface of the damping strip, and when the key tray slides inward or outward, the roller rolls along the surface of the damping strip, and since the damping strip contains a fluid and has a certain viscosity, a certain damping force is formed between the roller and the damping strip, so that when the drawer slides, a certain damping effect is generated on the drawer, which can reduce the sliding speed of the key tray, and avoid the key tray sliding too fast and causing a violent collision with the main chassis, thereby playing a buffering role. The greater the depth of the roller's immersion in the surface of the outer covering body, the greater the damping force between the roller and the damping strip, and vice versa. In the present invention, the length of the adjustment arm is adjustable, and by adjusting the length of the adjustment arm, the depth of the roller's immersion in the surface of the outer covering body can be adjusted, thereby adjusting the damping effect between the roller and the damping strip. In the present invention, the adjustment arm is arranged on the elastic claws, and when the ball head is inserted into or pulled out from between the two elastic claws, the two elastic claws will be stretched to both sides by the ball head; in the process of inserting and pulling out the ball head, the ball head will be subject to certain resistance, and a large force is required to complete the insertion and pulling out of the ball head; in the present invention, the adjustment arm is fixed on one of the elastic claws, and when the elastic claw is stretched out, the elastic claw will drive the adjustment arm to move, and in this process, the roller will be away from the damping strip, and the damping between the roller and the damping strip disappears; the effect of this is that when the ball head is inserted and pulled out, the roller will move to a position away from the damping strip and disengage from the damping strip, and the damping force between the roller and the damping strip disappears, so that the ball head will not be affected by the damping force in the process of inserting and pulling out, and the force required for inserting and pulling out the ball head is smaller, so that the ball head can be inserted or pulled out from between the elastic claws more easily. The fluid in the outer coating can be selected from water, oil, damping liquid or other fluid substances.

[0012] Preferably, the adjustment arm comprises an outer sleeve and an inner telescopic rod, wherein the inner telescopic rod is slidably connected to the outer sleeve, and a locking screw for locking the inner telescopic rod is threadedly connected to the outer sleeve; one end of the outer sleeve is fixed to the elastic claw, and a connecting arm is provided at the end of the inner telescopic rod away from the outer sleeve, and the roller is rotatably connected to the connecting arm. When adjusting the length of the adjustment arm, first loosen the locking screw, move the inner telescopic rod to the desired position, and finally lock the inner telescopic rod by the locking screw.
[0013] The beneficial effects of the present invention are: 1. When the key panel is not in use, the key panel is hidden in the main box and will not occupy external space; 2. When the key panel is not in use, since the key panel is hidden in the main box, dust is not easy to fall on the surface of the key panel and a large amount of dust will not accumulate; 3. When the key panel is not in use, since the key panel is hidden in the main box, outsiders will not accidentally touch the key panel, thereby preventing them from inputting wrong commands, thereby ensuring the normal operation of the equipment.

DETAILED DESCRIPTION
[0020] The present invention will be further described below through specific implementation modes in conjunction with the accompanying drawings.
[0021] Embodiment 1:
[0022] like Figures 1 to 5As shown, a hidden key panel structure includes a main box 1 and a key panel. A key tray 2 is slidably connected to the main box 1, and the key panel is arranged above the key tray 2. A receiving cavity for accommodating the key tray 2 is arranged in the main box 1. A guide rail 5 is arranged on the main box 1, and a slider 6 matching the guide rail 5 is arranged on the key tray 2, and the slider 6 is slidably connected to the guide rail 5. Through the cooperation between the guide rail and the slider, a sliding connection is formed between the key tray and the main box.
[0023] A ball head 3 is provided at the lower end of the key tray 2, and a fixing block 9 is connected to the main chassis 1. The fixing block 9 is provided with an elastic claw group corresponding to the ball head. The elastic claw group is composed of two elastic claws 4 arranged opposite to each other. The elastic claws 4 are in an arc shape. The elastic claws 4 are integrally formed with the fixing block. The fixing block 9 and the elastic claws 4 are both made of plastic. An introduction slope 13 is provided on the end of the elastic claw 4 close to the ball head 3.
[0024] A fixed plate 8 is provided on the key tray 2, and the fixed plate 8 is provided along the sliding direction of the key tray 2, and the fixed plate 8 is located on one side of one of the elastic claws. The elastic claw is provided with an adjustable length adjustment arm 11, and the adjustment arm 11 includes an outer sleeve 14 and an inner telescopic rod 15, and the inner telescopic rod 15 is slidably connected in the outer sleeve 14, and the outer sleeve 14 is threadedly connected with a locking screw 17 for locking the inner telescopic rod 15. One end of the outer sleeve 14 is fixed on the elastic claw, and the end of the inner telescopic rod away from the outer sleeve is provided with a connecting arm 16, and the connecting arm 16 is rotatably connected with a roller 12. When adjusting the length of the adjustment arm, first loosen the locking screw, move the inner telescopic rod to the desired position, and finally lock the inner telescopic rod by the locking screw. A damping strip is provided on the side of the fixed plate 8 close to the roller 12, and the damping strip is provided along the length direction of the fixed plate 8. The damping strip includes an outer covering body 10, and the outer covering body 10 is made of a flexible material. In the present invention, the outer coating 10 is made of rubber. The outer coating 10 contains fluid. The fluid in the outer coating can be water, oil, damping liquid or other fluid substances. The roller 12 contacts the surface of the outer coating 10. In the present invention, the roller is sunk to a certain depth in the surface of the damping strip. When the key tray slides inward or outward, the roller will roll along the surface of the damping strip. Since the damping strip contains fluid and the fluid has a certain viscosity, a certain damping force will be formed between the roller and the damping strip, so that when the drawer slides, a certain damping effect is generated on the drawer, which can reduce the sliding speed of the key tray, and avoid the key tray sliding too fast and causing a violent collision with the main chassis, thereby playing a buffering role. The greater the depth of the roller's immersion in the surface of the outer covering body, the greater the damping force between the roller and the damping strip, and vice versa. In the present invention, the length of the adjustment arm is adjustable, and by adjusting the length of the adjustment arm, the depth of the roller's immersion in the surface of the outer covering body can be adjusted, thereby adjusting the damping effect between the roller and the damping strip. In the present invention, the adjusting arm is arranged on the elastic claws, and when the ball head is extended between the two elastic claws or the ball head is pulled out from between the two elastic claws, the two elastic claws will be stretched to both sides by the ball head; in the process of extending and pulling out the ball head, the ball head will be subject to a certain resistance, and at this time, a large force is required to complete the extension and withdrawal of the ball head; in the present invention, the adjusting arm is fixed on one of the elastic claws, and when the elastic claws are stretched out, the elastic claws will drive the adjusting arm to move, during which the roller will move away from the damping strip, and the damping between the roller and the damping strip disappears; the effect achieved is that when the ball head is inserted and pulled out, the roller will move to a position away from the damping strip and disengage from the damping strip, during which the damping force between the roller and the damping strip disappears, so that the ball head will not be affected by the damping force during the extension and withdrawal process, and the force required for inserting and pulling out the ball head is smaller, so that the ball head can be extended or pulled out from between the elastic claws more easily.
[0025] In the present invention, when the key panel needs to be used, the key tray can be pulled outward, so that the key panel can be operated, thereby inputting corresponding instructions to the main control computer; after use, the key tray is pushed into the main box, so that the key panel is hidden in the main box. When the key tray is pushed to the bottom, the ball head set on the key tray just extends between the two elastic claws, and the two elastic claws hold the ball head, so that the key tray will not slide out easily. The advantages of the above structure are: 1. When the key panel is not in use, the key panel is hidden in the main box and will not occupy external space; 2. When the key panel is not in use, since the key panel is hidden in the main box, the surface of the key panel is not easy to fall dust, and a large amount of dust will not accumulate; 3. When the key panel is not in use, since the key panel is hidden in the main box, outsiders will not accidentally touch the key panel, thereby not inputting wrong instructions, ensuring the normal operation of the equipment.
