[0032] In the related art, the utility model with patent number CN 213634424U discloses a variable gasket-type keyboard fixing structure, including a lower shell, six fixed insert-type gaskets are fixed around the inner wall of the lower shell, and a slot is provided between two adjacent fixed insert-type gaskets, and four movable insert-type gaskets are inserted and fixed inside the slot, a main control board is installed inside the lower shell, and a positioning frame is fixed around the lower shell above the main control board, and a key module in contact with the main control board is installed inside the positioning frame, and a key cap module is fixed on the top of the key module. It is provided with six fixed insert-type gaskets and four movable insert-type gaskets, and the four movable insert-type gaskets are selectively installed by the user according to his own needs, and the rebound force is changed by changing the number of movable insert-type gaskets to meet different hand feeling requirements, breaking the situation that there is no keyboard on the market that can adjust the hand feeling. The above-mentioned variable gasket-type keyboard fixing structure requires the keyboard to be disassembled and assembled to adjust the soft feeling of the keyboard, which is troublesome to use and the adjustment efficiency is not high. Compared with the prior art, the keyboard pressure softness adjustment device controls the movement of the adjustment plate through a knob, so that the pad can move toward or away from the soft pad, thereby controlling the size of the adjustment space and then changing the compression amount of the soft pad, thereby providing different pressure softness for the key module. The operation is simple and convenient, the structure is simple and reliable, and the production cost is low.

[0033] like Figures 1 to 3 As shown, the embodiment of the present application provides a keyboard pressing soft feeling adjustment device, comprising:

[0034] The PCB board 100 has a plurality of key modules 110 mounted thereon; the pad 200 has a first surface and a second surface disposed opposite to each other, the first surface faces the PCB board 100, an adjustment space 210 is formed between the first surface and the PCB board 100, and positioning flanges 220 are spaced apart on the second surface; a soft pad (not shown) is mounted in the adjustment space 210; an adjustment plate 300 has an adjustment surface facing the pad 200, and adjustment sliders 310 are spaced apart on the adjustment surface, and the adjustment plate 300 is also provided with An adjustment mechanism 320 that can selectively cooperate with the positioning flange 220, the adjustment mechanism 320 includes a first cooperation groove 321, a second cooperation groove 322, and a third cooperation groove 323, the first cooperation groove 321 is located on the adjustment surface and on one side of the adjustment slider 310, the second cooperation groove 322 and the third cooperation groove 323 are spaced apart on the adjustment slider 310; the knob 400 is rotatably arranged on the side of the adjustment plate 300 facing away from the pad 200, and the knob 400 is provided with a driving mechanism 410 that passes through the adjustment plate 300.

[0035] When the keyboard soft-pressing feeling adjustment device is installed in the keyboard, the PCB board abuts against the keyboard housing, so that the PCB board is stationary relative to the keyboard housing.

[0036] The backing plate 200 has a plurality of guide posts extending upwards for the PCB 100 to be mounted therein, so that the backing plate 200 and the PCB 100 can move relative to each other. The backing plate 200 has a plurality of receiving grooves on its second surface, and the shapes of the receiving grooves match the shapes of the adjusting slider 310. When the positioning flange 220 is in the first matching groove 321, the adjusting slider 310 is received in the receiving groove.

[0037] Furthermore, the adjusting slider 310 and the positioning flange 220 are both provided in multiple numbers, and the number is the same. The surface on which the adjusting slider 310 and the positioning flange 220 slide relative to each other is not a plane. Further, the adjusting slider 310 includes a first inclined surface, a second inclined surface, and a plane. The first inclined surface, the second inclined surface, and the plane are connected in sequence. The first inclined surface is connected to the adjusting surface. The angle between the first inclined surface and the adjusting surface is greater than the angle between the second inclined surface and the adjusting surface. The second matching groove 322 is located between the first inclined surface and the second inclined surface, and the third matching groove 323 is located on the plane.

[0038] like Figures 1 to 3As shown, in some embodiments, the first matching groove 321, the second matching groove 322, and the third matching groove 323 are all circular grooves. The positioning flange 220 is hemispherical. The positioning flange 220 is adapted to the shapes of the first matching groove 321, the second matching groove 322, and the third matching groove 323, which can improve the stability of the positioning flange 220 when it is matched with the first matching groove 321, the second matching groove 322, and the third matching groove 323, thereby preventing the positioning flange 220 from coming out of the first matching groove 321, the second matching groove 322, and the third matching groove 323.

[0039] like Figures 1 to 3 As shown, in some embodiments, the adjusting plate 300 is provided with a limiting groove 330, and the backing plate 200 is provided with a limiting screw 230 that cooperates with the limiting groove 330. The limiting groove 330 cooperates with the limiting screw 230 to limit the freedom of movement of the adjusting plate 300, so that the movement of the adjusting plate 300 is controllable.

[0040] The limiting groove 330 is a waist-shaped groove and penetrates the adjustment plate 300. The limiting groove 330 extends along the length direction of the adjustment plate 300, thereby restricting the movable direction of the adjustment plate 300.

[0041] like Figures 1 to 3 As shown, in some embodiments, the driving mechanism 410 includes a driving pin 411, which is located at one end of the knob 400 facing the adjustment plate 300, and the driving pin 411 is inserted into the adjustment plate 300. Specifically, the adjustment plate 300 is driven to move by the movement of the driving pin 411, which is easy to operate. The knob 400 is set at the bottom of the keyboard for easy adjustment without disassembling the keyboard.

[0042] For example, when the keyboard soft feeling adjustment device is in use, the positioning flange 220 moves from the first mating groove 321 to the third mating groove 323 relative to the adjustment mechanism 320, the adjustment space 210 between the pad 200 and the PCB board 100 is compressed, and the compression amount of the soft pad increases, thereby reducing the soft feeling of pressing.

[0043] For example, when the keyboard soft feeling adjustment device is in use, the positioning flange 220 moves from the third matching groove 323 to the first matching groove 321 relative to the adjustment mechanism 320, the adjustment space 210 between the pad 200 and the PCB board 100 expands, and the compression of the soft pad decreases, thereby increasing the soft feeling of pressing.

[0044] The above are only preferred embodiments of the present application, and do not constitute any formal limitation on the present application. Any technician familiar with the art can use the above disclosed methods and technical contents to make many possible changes and modifications to the technical solution of the present application without departing from the scope of the technical solution of the present application, or modify it into an equivalent embodiment of equivalent changes. Therefore, all equivalent changes made according to the shape, structure and principle of the present application without departing from the content of the technical solution of the present application should be included in the protection scope of the present application.
