[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figure 1 and Figure 2 , an embodiment provided by the present utility model: a magnetic induction shaft keyboard structure with a soft elastic structure for the integral module, including an upper cover 1, a lower cover 2, a keycap 3, an integral module 4 and a bottom elastic cotton 5. The upper cover 1 and the lower cover 2 are buckled to form a cavity structure with an opening at the upper end and a hollow interior. The keycap 3 is arranged at the upper end opening of the cavity. The integral module 4 is arranged in the cavity, and the integral module 4 includes a shaft body 41, a positioning plate 42, a sandwich cotton 43, an IXPE under-axle pad 44, a PET voice actor pad 45 and a PCBA board 46 arranged in sequence from top to bottom in the cavity. Among them, a plurality of shaft bodies 4 are provided, and the plurality of shaft bodies 4 correspond to the keycaps 3. One end of the shaft body 41 is connected to the keycap 3, and the other end sequentially penetrates through the positioning plate 42, the sandwich cotton 43, the IXPE under-axle pad 44 and the PET voice actor pad 45 from top to bottom and is electrically inductively connected to the PCBA board 46. The bottom elastic cotton 5 is arranged at the bottom position of the lower cover 2.

[0023] Specifically, through holes 6 for the shaft body 41 to penetrate are formed in the positioning plate 42, the sandwich cotton 43, the IXPE under-axle pad 44 and the PET voice actor pad 45.

[0024] Specifically, the positioning plate 42 is an iron plate positioning plate, which is mainly used to limit the shaft body 41.

[0025] Please refer to Figure 3 and Figure 4 , in the figures, the shaft body 41 is composed of a housing 411, a shaft core 412, a magnet 413, a spring 414 and an LED lamp socket 415. Among them, a guide post 417 is arranged on the shaft core 412. After the guide post 417 is inserted into the housing 411, it is inserted into the spring 414. An installation groove 418 is arranged on the shaft core 412 on one side of the guide post 417. The magnet 413 is installed in the installation groove 418. In this embodiment, the magnet 413 is columnar and is arranged parallel to the guide post 417. A positioning post 416 is arranged on the housing 411. The LED lamp socket 415 is inserted into the positioning post 416, and an LED lamp 419 is electrically connected to the LED lamp socket 415. The LED lamp 419 is electrically connected to the above-mentioned PCBA board 46.

[0026] Specifically, the housing 411 is formed by buckling an upper shell 4111 and a lower shell 4112. A light guide column 4110 is arranged on the lower shell 4112. The light guide column 4110 is located above the LED lamp 419, and the light emitted by the LED lamp 419 is led out from the light guide column 4110.

[0027] Please refer to again Figures 1 to 4 , a Hall element 7 matching the magnet 413 is arranged on the PCBA board 46. The Hall element 7 is coaxially arranged with the magnet 413. When the shaft core 412 on the shaft body 41 is pressed, the magnet 413 moves in the direction of the pressing of the shaft core 412. The Hall element 7 senses the magnetic field signal of the magnet 413 to achieve the purpose of switching signals.

[0028] Please refer to again Figures 1 to 4 , when the magnetic induction shaft keyboard in the present invention is assembled, the positioning plate 42 and the PCBA board 46 are respectively fixed by screws (not shown in the figure). The sandwich cotton 43, the IXPE shaft gasket 44 and the PET voice gasket 45 are used to form the soft and elastic structure of the magnetic induction shaft keyboard. Under the action of the soft and elastic structure, when the keycap 3 is pressed, the keycap 3 drives the shaft body 41 to achieve up and down soft elasticity, and the up and down soft elasticity does not affect the inductive electrical conduction between the shaft body 41 and the PCBA board 46, thereby improving the user experience when using. Of course, the soft and elastic structure in this embodiment can also be applied to other keyboards, such as the optical induction shaft keyboard. The structure of the optical induction shaft keyboard is basically the same as that of the magnetic induction shaft keyboard, and will not be elaborated here.

[0029] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-mentioned exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
