[0020] The utility model is further described in detail below in conjunction with the accompanying drawings and specific embodiments. In order to clearly and completely describe the technical solution, the following embodiments are selected for illustration; the following embodiments are part of the embodiments of the utility model; based on this application, other embodiments obtained without creative work are all within the scope of protection of the utility model.

[0021] In the following embodiments, it should be noted that the terms "upper", "lower", "left", "right", "inner", "outer", "top / bottom" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of clearly describing the present embodiment, rather than indicating or implying that the device or element referred to must have a specific direction, and therefore cannot be understood as a limitation on the present application. At the same time, "first" and "second" in the embodiments are only used for distinguishing description purposes, and do not represent or imply relative importance.

[0022] like Figure 1-5 As shown, the specific embodiment of the utility model is an ultra-thin key assembly that is easy to replace. The ultra-thin key comprises a key cap 1 and a linkage member 3 disposed under the key cap 1. The ultra-thin key is assembled on a PCB board 6 through a mounting plate 2. The linkage member 3 is connected to the mounting plate 2. The mounting plate 2 is configured as an independent piece corresponding to the ultra-thin key. A fixing frame 5 is fixedly disposed on the PCB board 6. The fixing frame 5 has a hollow structure corresponding to the mounting plate 2. The mounting plate 2 is pluggable and embedded in the hollow structure of the fixing frame 5. In order to stabilize the fixing frame 5, a support plate 4 is installed above the fixing frame 5. The support plate 4 has a hollow structure corresponding to the fixing frame 5.

[0023] The inner wall of the fixed frame 5 protrudes upward with a limit groove 501, and the two sides of the mounting plate 2 extend outward with limit protrusions 201, and the mounting plate 2 is pluggably embedded in the limit groove 501 of the fixed frame 5 through the limit protrusions 201. The two sides of the mounting plate 2 extend outward with limit protrusions 201, and the mounting plate 2 is pluggably embedded in the limit groove 501 of the fixed frame 5 through the limit protrusions 201. Through this pluggable design, when the components of the key are damaged or need to be replaced, they can be easily removed from the fixed frame 5 and replaced individually without disassembling the entire keyboard, which greatly reduces the maintenance cost.

[0024] The limiting protrusion 201 of the mounting plate is preferably a wedge-shaped structure, the upper part of the limiting protrusion 201 remains parallel to the mounting plate 2, and the lower part of the limiting protrusion 201 is inclined outward and upward. Since the lower part of the limiting protrusion 201 is an inclined structure, when the limiting protrusion 201 enters the limiting groove 501, it can naturally slide inward and lock in the limiting groove 501. After installation, even under the action of external force, the linkage member 3 is not easy to fall off from the fixed frame 5.

[0025] Two limiting protrusions 201 are respectively provided on the left and right sides of the mounting plate 2, and the limiting grooves 501 correspond to the positions of the limiting protrusions 201 one by one. The limiting protrusions 201 on one side of the mounting plate 2 are arranged on both sides, and the limiting protrusions 201 on the other side of the mounting plate 2 are arranged in the middle. This layout makes the mounting plate 2 more evenly subjected to external force, and can be used as an alignment reference for easy installation.

[0026] The linkage member 3 of the key assembly is a wing frame assembled between the mounting plate 2 and the key cap 1. The wing frame is composed of a first wing and a second wing that are mutually linked and twisted, and a reset tension spring is connected between the first wing and the second wing. It also includes electrical components located on the PCB board 6. The mounting plate 2 is provided with a clearance groove 202 for accommodating the electrical components, so that the electrical components have enough space to be installed on the mounting plate 2 without occupying additional space.

[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any minor modifications, equivalent replacements and improvements made to the above embodiments based on the technical essence of the present invention should be included in the protection scope of the technical solution of the present invention.
