[0021] In order to facilitate the understanding of those skilled in the art, the present application will be further described below in conjunction with the embodiments and the drawings, and the contents mentioned in the embodiments are not limitations of the present application. The present application will be described in detail below in conjunction with the drawings.

[0022] Please refer to Figures 1-5A specific implementation of the keyboard includes a base 1, keycaps 2, and switches 3. The top surface of the base 1 is provided with a downwardly recessed groove 11. The switches 3 are disposed inside the groove 11. The keycaps 2 are detachably fixed to the top of the switches 3. The keycaps 2 can be lowered into the groove 11 by pressing the switches 3. The bottom edge of the keycaps 2 and the inner wall of the groove 11 are both made of polyurethane resin. Preferably, the keycaps 2 and the base 1 are both made of polyurethane resin in an integrated structure.

[0023] The bottom edge of the keycap 2 and the inner wall of the recessed groove 11 of the base 1 are all integrally formed with polyurethane resin. The elastomer of polyurethane resin has the characteristics of heat insulation, sound absorption and soft texture, which can effectively reduce the collision sound between the keycap 2 and the keyboard base 1 when it rebounds, and effectively achieve the effect of low noise.

[0024] Specifically, such as Figure 2 As shown, the upper edge of the base 1 is provided with a Type-C interface 13 for power supply.

[0025] In further plans, such as Figures 3-4 As shown, the bottom surface of the upper edge of the base 1 is provided with an angle adjustment component 4. The angle adjustment component 4 includes a support block 41 and a wedge block 42. The support block 41 is vertically and movably disposed on the bottom surface of the upper edge of the base 1. The wedge block 42 is horizontally and movably disposed inside the base 1. The bottom surface of the wedge block 42 is a ramp surface 421 that is inclined to one side. The wedge block 42 abuts against the top of the support block 41 through the ramp surface 421.

[0026] Specifically, such as Figure 3 As shown, the angle adjustment assembly 4 also includes a lead screw 43 and a cap 44. One end of the lead screw 43 is fixedly connected to the cap 44, the middle part of the lead screw 43 is rotatably connected to the upper edge of the base 1, and the other end of the lead screw 43 is threadedly connected to the inside of the wedge block 42. The end of the support block 41 away from the wedge block 42 is an arc surface 411. When the keyboard's facing angle is adjusted by the angle adjustment assembly 4, the lead screw 43 can be rotated within the base 1 by rotating the cap 44. Simultaneously, due to the threaded connection between the lead screw 43 and the wedge block 42, the wedge block 42 can move horizontally under the drive of the lead screw 43. At the same time, the wedge block 42 abuts against the top of the support block 41 via the inclined platform 421. The support block 41 can extend and retract vertically at the bottom edge of the upper edge of the base 1, thereby achieving the effect of adjusting the keyboard's facing angle.

[0027] The above is only the preferred embodiment of the present application, and does not limit the present application in any form. Although the present application is disclosed as above in the preferred embodiment, it is not intended to limit the present application. Any skilled person in the art can make some changes or modifications to the disclosed technical content without departing from the technical solution of the present application, and any equivalent embodiment with equivalent changes is equivalent to the above embodiment. Any simple modification, equivalent change and modification of the above embodiment according to the present application technical solution are within the scope of the present application technical solution.
