[0028] 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.
[0029] The utility model embodiment discloses a key structure to prevent the scissor legs from spreading out when falling, such as Figure 1-8 As shown, it includes: a keycap 1, an inner shear 2, an outer shear 3, a first base plate 4 and a second base plate 5, the inner shear 2 is hinged in the outer shear 3, one end of the outer shear 3 is clamped with the second base plate 5, the other end of the outer shear 3 is clamped with the keycap 1, one end of the inner shear 2 is clamped with the keycap 1, and the other end of the inner shear 2 is clamped with the second base plate 5, a first limiting convex bone 11 and a second limiting convex bone 12 are provided in the keycap 1, the first limiting convex bone 11 is used to limit the side wall of the outer shear 3, the second limiting convex bone 12 is used to limit the inner wall of the inner shear 2, and the first base plate 4 is abutted against the second base plate 5.
[0030] It should be noted that the first limiting protrusion 11 is used to limit the side wall of the outer scissors 3, and the second limiting protrusion 12 is used to limit the inner wall of the inner scissors 2, thereby providing a button structure that can prevent the scissors legs from dispersing when they fall. The scissors legs can be limited to prevent the button structure from dispersing during a drop test.
[0031] like Figure 5 As shown, the key cap 1, the first limiting protrusion 11 and the second limiting protrusion 12 are an integrally formed structure.
[0032] like Figure 5 As shown, the first limiting convex bone 11 and the second limiting convex bone 12 are both arranged in an L shape. It should be noted that since the first limiting convex bone 11 and the second limiting convex bone 12 are both arranged in an L shape, it is convenient to limit the outer shear 3 and the inner shear 2 to prevent the scissors from spreading due to the drop test.
[0033] like Figure 2-8 As shown, the outer shear 3 is relatively provided with a first clamping column 31 and a second clamping column 32, the second bottom plate 5 is provided with a first clamping buckle 51 which is clamped and matched with the first clamping column 31, and the key cap 1 is provided with a second clamping buckle 13 which is clamped and matched with the second clamping column 32. In the specific implementation process, the outer shear 3, the first clamping column 31 and the second clamping column 32 are an integrally formed structure.
[0034] like Figure 2-6 As shown, the inner shear 2 is provided with a third clamping column 21 and a fourth clamping column 22, the second bottom plate 5 is provided with a third clamping buckle 52 engaged with the third clamping column 21, and the key cap 1 is provided with a fourth clamping buckle 14 engaged with the fourth clamping column 22. In the specific implementation process, the inner shear 2, the third clamping column 21 and the fourth clamping column 22 are an integrally formed structure, the key cap 1, the second clamping buckle 13 and the fourth clamping buckle 14 are an integrally formed structure, and the second bottom plate 5, the first clamping buckle 51 and the third clamping buckle 52 are an integrally formed structure.
[0035] like Figure 7 As shown, the outer shear 3 is provided with a hinge hole 33, and the side wall of the inner shear 2 is provided with a hinge column 23 hinged to the hinge hole 33. In the specific implementation process, the number of the hinge column 23 and the hinge hole 33 is set to two, and the inner shear 2 and the outer shear 3 are cross-hinged.
[0036] like Figure 6 As shown, the inner cutter 2 is provided with an abutment groove 24, and the outer cutter 3 is provided with an abutment protrusion 34 corresponding to the abutment groove 24. It should be noted that, through the arrangement of the abutment groove 24 and the abutment protrusion 34, when the user strikes the keycap 1, the inner cutter 2 and the outer cutter 3 are positioned and abutted, which facilitates pressing the key.
[0037] like Figure 1-4 As shown, an elastic member 6 is installed between the keycap 1 and the first base plate 4. It should be noted that one end of the elastic member 6 abuts against the first base plate 4, and the other end of the elastic member 6 abuts against the keycap 1; the elastic member 6 plays an elastic role, which facilitates the rebound of the keycap 1 and facilitates operation.
[0038] Working principle: The first limiting convex bone 11 limits the side wall of the outer scissors 3, and the second limiting convex bone 12 limits the inner wall of the inner scissors 2, thereby providing a button structure that prevents the scissors legs from dispersing when falling. The scissors legs can be limited to prevent the button structure from dispersing during a drop test.
[0039] 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.
