[0005] The technical solution adopted by this utility model is as follows: the spring structure includes a first spring and a second spring, both of which are inclined and intersecting. A rotating member is provided in the middle of both the first and second springs, and the two rotating members are rotatably connected. The upper end of the first spring is located above the lower end of the second spring, and the upper end of the second spring is located above the lower end of the first spring. A first connecting part is provided at the upper end of both the first and second springs, and the first connecting part is connected to the keyboard inner tube. A second connecting part is provided at the lower end of both the first and second springs, and the second connecting part is connected to the keyboard lower cover.
[0006] Furthermore, both the first and second spring pieces include a spring piece body, a first horizontal spring piece, and a second horizontal spring piece. The spring piece body is inclined, and the first and second horizontal spring pieces are located at the upper and lower ends of the spring piece body, respectively. The first connecting portion and the second connecting portion are located on the first and second horizontal spring pieces, respectively.
[0007] Furthermore, the first connecting part includes a connecting seat and a connecting post. The connecting seat is disposed on the keyboard inner tube. The upper ends of the first spring and the second spring are both opened. The connecting seat is located at the upper end of the connecting post. The lower end of the connecting post passes through the opening from top to bottom and is connected to a locking block. The locking block abuts against the lower end of the opening.
[0008] Furthermore, the connector is snapped onto the side of the keyboard inner tube.
[0009] Furthermore, the connector has two slots, and the side of the keyboard insert has two blocks that engage with the two slots respectively.
[0010] Furthermore, the second connecting part includes a plurality of connecting members.

[0012] The beneficial effects of this utility model are:
[0013] In contrast to the shortcomings of existing technologies, in this invention, when the user presses the keycap, the keyboard inner shell presses down, causing the two first connecting parts to press down on the first and second springs respectively. The upper ends of the first and second springs swing downwards, and the two rotating parts rotate relative to each other. This provides the user with a better tactile feel through the elasticity of the springs. Therefore, this invention changes the user's tactile feel when typing by utilizing the elasticity of the springs. The direction of the force generated is perpendicular to the vertical direction of the keyboard surface, preventing the spring structure from shifting left or right and thus providing a better tactile feel. This makes the spring structure have the advantages of good tactile feel and no left or right shift. Attached Figure Description

[0026] like Figures 1 to 5As shown, in this embodiment, the present invention includes a first spring 1 and a second spring 2. The first spring 1 and the second spring 2 are both inclined and distributed in a crisscross pattern. A rotating member 3 is provided in the middle of the first spring 1 and the second spring 2. The two rotating members 3 are rotatably connected to each other. The upper end of the first spring 1 is located above the lower end of the second spring 2, and the upper end of the second spring 2 is located above the lower end of the first spring 1. A first connecting part 5 is provided at the upper end of the first spring 1 and the second spring 2. The first connecting part 5 is connected to the keyboard inner tube 6. A second connecting part 7 is provided at the lower end of the first spring 1 and the second spring 2. The second connecting part 7 is connected to the keyboard lower cover 8.
[0027] In contrast to the shortcomings of existing technologies, in this invention, when the user presses the keycap, the keyboard inner tube 6 presses down, causing the two first connecting parts 5 to press down on the first spring 1 and the second spring 2 respectively. The upper ends of the first spring 1 and the second spring 2 swing downward, and the two rotating parts 3 rotate relative to each other. Thus, the elasticity of the springs provides the user with a better tactile feel. Therefore, this invention changes the user's tactile feel when typing by utilizing the elasticity of the springs. The direction of the force generated is perpendicular to the vertical direction of the keyboard placement surface, preventing the spring structure from shifting left or right and thus providing a better tactile feel. This makes the spring structure have the advantages of good tactile feel and no left or right shift.
[0028] In some embodiments, both the first spring 1 and the second spring 2 include a spring body 9, a first horizontal spring 10 and a second horizontal spring 11.

[0029] In some embodiments, the first connecting part 5 includes a connecting seat 12 and a connecting post 13. The connecting seat 12 is disposed on the keyboard inner tube 6. The upper ends of the first spring 1 and the second spring 2 are both provided with openings 16. The connecting seat 12 is located at the upper end of the connecting post 13. The lower end of the connecting post 13 passes through the opening 16 from top to bottom and is connected to a locking block 15. The locking block 15 abuts against the lower end of the opening 16. The connecting seat 12 is engaged with the side end of the keyboard inner tube 6. The connecting seat 12 has two slots 21. The side end of the keyboard inner tube 6 is provided with two locking blocks 22, which are respectively engaged in the two slots 21. Specifically, since the two locking blocks 22 are respectively engaged in the two slots 21, when the keyboard inner tube 6 presses down on the connecting seat 12, the pressing force is ensured to be from top to bottom, further ensuring that the spring structure does not shift left or right.
[0030] In some embodiments, the second connecting portion 7 includes a plurality of connectors 17. Specifically, the lower ends of the first spring 1 and the second spring 2 are connected to the keyboard lower cover 8 via the plurality of connectors 17.
[0031] Furthermore, this utility model provides a keyboard, which includes a keyboard upper cover 18, a keyboard lower cover 8, a keyboard inner tube 6, and a plurality of the aforementioned spring-loaded structures.
