[0027] The technical solution of the present utility model will be further described below with reference to the accompanying drawings.

[0028] Example 1: Figures 1 to 6 The present invention discloses a keyboard scissor structure, comprising an inner bracket 1 and an outer bracket 2, which are connected inside and outside. The inner bracket 1 and the outer bracket 2 are made of hard plastic and are hingedly connected by a flexible connector 3 made of rubber or silicone. The middle height of the flexible connector 3 is less than the height of the inner bracket, forming a central axis for relative rotation between the inner bracket 1 and the outer bracket 2. The side of the flexible connector 3 connected to the inner bracket 1 is a first side 31, and the side connected to the outer bracket 2 is a second side 32. The first side 31 and the second side 32 both extend to the upper and lower surfaces of the inner bracket 1 and the outer bracket 2, forming upper and lower side pages clamped on the upper and lower surfaces of the inner bracket 1 and the outer bracket 2, respectively, for cushioning and reducing the impact between the inner bracket 1 and the outer bracket 2 and the keycap 7 or the base plate 4. The upper and lower side pages clamped on the upper and lower surfaces of the inner bracket 1 and the outer bracket 2 are embedded in the upper and lower surfaces of the inner bracket 1 and the outer bracket 2.

[0029] like Figure 5 、 Figure 6 The ends of the upper and lower side pages of the first side 31 and the inner side (the side away from the outer bracket 2) where the upper and lower side pages contact the side wall of the inner bracket 1 are provided with reinforcing ribs 311 that pass through the inner bracket 1 and connect the upper and lower side pages. The ends of the upper and lower side pages of the second side 32 and the inner side (the side away from the inner bracket 1) where the upper and lower side pages contact the side wall of the outer bracket 2 are provided with reinforcing ribs 321 that pass through the outer bracket 2 and connect the upper and lower side pages. The width of the reinforcing ribs 311 and 321 is smaller than the width of the side pages of the first side 31 and the second side 32.

[0030] On the second side 32, a buffer structure 33 is connected to the side leaf at the top of the outer bracket 2. The connecting section of the buffer structure 33 is embedded in the upper surface of the outer bracket 2, with the end bent downward, extending through the outer bracket 2, forming a protruding buffer end 331 on the lower surface of the outer bracket 2. When the keycap 7 is pressed, the buffer end 331 first contacts the base plate 4, providing a buffer. The buffer end 331 is staggered / offset with the side leaf at the bottom of the second side 32 to increase the buffering range.

[0031] like Figure 3 、 Figure 4The outer side wall of the inner bracket 1 is symmetrically provided with a first protrusion 11 that deviates from the center line, and the inner wall of the outer bracket 2 is correspondingly provided with a first recess that avoids the first protrusion; the inner side wall of the outer bracket 2 is symmetrically provided with a second protrusion 21 that deviates from the center line, and the outer side wall of the inner bracket 1 is correspondingly provided with a second recess that avoids the second protrusion 21. The flexible connector 3 is installed between the first protrusion 11 of the inner bracket and the second protrusion 21 of the outer bracket: the upper and lower side pages of the first side 31 clamp and embed in the top and bottom surfaces of the first protrusion 11, and the first protrusion 11 is provided with a mounting hole (not shown) that surrounds the reinforcement rib 311 and is used to install the reinforcement rib 311; the upper and lower side pages of the second side 32 clamp and embed in the top and bottom surfaces of the second protrusion 21, and the second protrusion 21 is provided with a mounting hole (not shown) that surrounds the reinforcement rib 321 and is used to install the reinforcement rib 321.

[0032] Example 2: Based on Example 1, this example can also have the following variations:

[0033] like Figure 7 、 Figure 8 The first side 31 and the second side 32 of the flexible connector 3 only extend to the bottom of the inner bracket 1 and the outer bracket 2, forming side leaves that pad the lower surfaces of the inner bracket 1 and the outer bracket 2, and the side leaves are embedded in the lower surfaces of the inner bracket 1 and the outer bracket 2. The end of the inner side of the lower side leaf of the first side 31 (the side that contacts the side wall of the inner bracket 1) is provided with a vertical reinforcing rib 311 that passes through the inner bracket 1. The first protrusion 11 is provided with a mounting hole that surrounds the outer side 311 of the reinforcing rib and is used to install the reinforcing rib 311. The end of the inner side of the lower side leaf of the second side 32 (the side that contacts the side wall of the outer bracket 2) is provided with a reinforcing rib 312 that passes through the outer bracket 2. The second protrusion 21 is provided with a mounting hole that surrounds the outer side 321 of the reinforcing rib and is used to accommodate the reinforcing rib 321. The reinforcing rib 321 is connected to the buffer structure 33.

[0034] Example 3: Based on Example 2, this example can also have the following variations: Figure 9 、 10 The first side 31 and second side 32 are respectively inserted into the first protrusion 11 and second protrusion 21, and connected to the middle of the inner bracket 1 and outer bracket 2. Each of the first side 31 and second side 32 is provided with a reinforcing rib perpendicular to itself, extending through the upper and lower surfaces of the inner bracket 1 and outer bracket 2. A buffer structure 33 is connected to the reinforcing rib on the second side 32.

[0035] Example 4: Figure 11A keyboard key structure includes several single keys, each of which is primarily composed of a keycap 7, any one of the scissor structures described in Examples 1 to 3, a dome switch 6 (rubber dome), a membrane circuit 5 (membrane), and a base plate 4. The membrane circuit 5 is connected to the base plate 4, with the dome switch 6 positioned in the center. After assembly, the scissor structure is sleeved over the dome switch 6. The front end of the inner bracket 1 and the rear end of the outer bracket 2 are connected to the base plate 4, while the other opposite ends (the rear end of the inner bracket 1 and the front end of the outer bracket 2) are connected to the keycap 7. The keycap 7 is disposed over the dome switch 6 and the scissor structure.
