[0024] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0025] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, it can also be the internal connection of two components, it can be a wireless connection, or it can be a wired connection. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0026] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0027] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0028] The utility model embodiment discloses an ultra-thin key core scissor foot structure, such as Figure 1-7As shown, it includes: a keycap 1, an inner scissors 2, a long outer scissors 3 and a base plate 4. The inner scissors 2 have two and are installed in the long outer scissors 3. Two first buckles 11, two second buckles 12 and four third buckles 13 are distributed on the keycap 1. Two first clamping columns 31 and two second clamping columns 32 are provided on the long outer scissors 3. The first buckle 11 is clamped with the first clamping column 31, and the second buckle 12 is clamped with the second clamping column 32. Each inner scissors 2 is provided with a third clamping column 21 clamped with the third buckle 13. The base plate 4 is clamped with the inner scissors 2 and the long outer scissors 3 respectively.

[0029] It should be noted that, by respectively clamping the long outer scissors 3 with the keycap 1 and the base plate 4, the two first clips 11, the two second clips 12 and the four third clips 13 are set, so that the keycap 1 can be connected in eight positions, thereby providing an ultra-thin key core scissor foot structure, which does not require a balance bar, improves the stability of the scissor foot installation, reduces the assembly process, and reduces the production cost.

[0030] like Figure 1-4 As shown, an elastic member 5 in a compressed state is installed between the key cap 1 and the base plate 4. It should be noted that, through the arrangement of the elastic member 5, it is convenient for the key cap 1 to rebound, so that the user can press the key cap 1 conveniently.

[0031] like Figure 1-4 As shown, the bottom plate 4 is provided with four first cards 41 and four second cards 42, the long outer scissors 3 are provided with first connecting posts 33 connected with the first cards 41, each inner scissors 2 are provided with two second connecting posts 22, and the second cards 42 are connected with the second connecting posts 22. It should be noted that the scissor leg structure is conveniently connected by connecting the first cards 41 with the first connecting posts 33 and the second cards 42 with the second connecting posts 22.

[0032] like Figure 6 and Figure 7 As shown, the side wall of the inner shear 2 is provided with a boss 23, and the long outer shear 3 is provided with a groove 34 adapted to the boss 23. In the specific implementation process, the number of the boss 23 and the groove 34 is set to two, and the boss 23 and the groove 34 are tightly matched, so that the inner shear 2 is conveniently installed in the long outer shear 3.

[0033] like Figure 6 and Figure 7 As shown, the long outer scissors 3 are provided with abutment grooves 35 adjacent to the grooves 34, and the sidewalls of the inner scissors 2 are provided with abutment sheets 24 in contact with the abutment grooves 35. In the specific implementation process, each inner scissors 2 are provided with two abutment sheets 24, and the abutment sheets 24 abut against the abutment grooves 35, so as to facilitate the support of the inner scissors 2. When the user presses the keycap 1, the force on the scissor foot structure is more uniform, thereby improving the feel of the key.

[0034] like Figure 1-4As shown, the end of the inner shear 2 is suspended in the long outer shear 3. It should be noted that, since the end of the inner shear 2 is suspended in the long outer shear 3, it is convenient to punch and install the inner shear 2 in the long outer shear 3.

[0035] like Figure 5 and Figure 6 As shown, the long outer shear 3 is provided with a positioning protrusion 36, and the key cap 1 is provided with a positioning groove 14 corresponding to the positioning protrusion 36. It should be noted that the positioning protrusion 36 and the positioning groove 14 are positioned and matched to facilitate the positioning and installation of the key cap 1.

[0036] like Figure 1-5 As shown, the key cap 1, the first buckle 11, the second buckle 12 and the third buckle 13 are all integrally formed structures.

[0037] Working principle: The long outer scissors 3 are respectively connected with the keycap 1 and the base plate 4. The two first clips 11, the two second clips 12 and the four third clips 13 are set to enable the keycap 1 to be connected in eight positions, thereby providing an ultra-thin key core scissor foot structure, which does not require a balance bar, improves the stability of the scissor foot installation, reduces the assembly process, and reduces the production cost.

[0038] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
