[0049] As Figures 1 to 3 As shown in the figure, the application provides a foldable keyboard, which has a folding state and a flat state. The foldable keyboard includes a first keyboard body 1, a second keyboard body 2 and a third keyboard body 3.

[0050] The first keyboard body 1 has a plurality of first function area keys 11, and the first function area keys 11 include an ESC key, function keys F1 to F12, number keys 0 to 9, and part of letter keys. The first function area keys 11 are arranged in multiple rows in sequence; the second keyboard body 2 has a plurality of second function area keys 21, and the second function area keys 21 include the remaining letter keys, a case switching key, a line feed key, a carriage return key, and a space key, etc. The second function area keys 21 are arranged in multiple rows in sequence; and the third keyboard body 3 is integrated with a touchpad 31, so that the user can control the cursor to move and realize clicking, dragging, etc.

[0051] The second keyboard body 2 is hinged to one side of the first keyboard body 1 along the rows of the first function area keys 11; and the third keyboard body 3 is hinged to one side of the second keyboard body 2 along the rows of the second function area keys 21. When the foldable keyboard is in the unfolded state, the first keyboard body 1, the second keyboard body 2, and the third keyboard body 3 are laid flat on the working interface, which is convenient for the user to operate.

[0052] When the foldable keyboard is in the folded state, the first keyboard body 1, the second keyboard body 2, and the third keyboard body 3 are arranged in sequence and stacked, so as to reduce the occupied area of the foldable keyboard and improve the portability thereof.

[0053] As shown in Figures 1 to 3 , in one specific embodiment of the present application, when the foldable keyboard is in the folded state, the end face of the first keyboard body 1 on one side of the first function area keys 11 corresponds to and abuts against the end face of the second keyboard body 2 on one side of the second function area keys 21, so as to reduce the dust accumulated on the first function area keys 11 and the second function area keys 21. Correspondingly, the back of the second keyboard body 2 abuts against the back of the third keyboard body 3.

[0054] As shown in Figure 4 and Figure 5 , in one specific embodiment of the present application, the foldable keyboard comprises a first hinge structure 4. The first end of the first hinge structure 4 is hinged to the first keyboard body 1, and the second end of the first hinge structure 4 is hinged to the second keyboard body 2, so that the first keyboard body 1 can be folded relative to the second keyboard body 2.

[0055] As shown in Figure 4 and Figure 5 , in one specific embodiment of the present application, the first hinge structure 4 comprises a chain shell 41, a first rotating shaft 42 arranged on the first keyboard body 1, and a second rotating shaft 43 arranged on the second keyboard body 2. The first rotating shaft 42 penetrates the first end of the chain shell 41, and the second rotating shaft 43 penetrates the second end of the chain shell 41.

[0056] The first hinge structure 4 further comprises a first gear 44 sleeved on the first rotating shaft 42 and a second gear 45 sleeved on the second rotating shaft 43, the first gear 44 and the second gear 45 are arranged in the chain shell 41 and mesh with each other. When the first keyboard body 1 is folded relative to the second keyboard body 2, the first rotating shaft 42 drives the first gear 44 to rotate, thereby making the first gear 44 mesh with different meshing teeth on the second gear 45.

[0057] As shown in Figure 4 and Figure 5 In one specific embodiment of the present application, the number of first hinge structures 4 is at least two, and each first hinge structure 4 is arranged spaced apart from each other. Such a dispersed arrangement not only ensures the balance and stability of the first keyboard body 1 and the second keyboard body 2 during folding and unfolding, but also effectively avoids the risk of structural damage due to excessive force on a single point.

[0058] As shown in Figure 4 and Figure 6 In one specific embodiment of the present application, the foldable keyboard comprises a second hinge structure 5, the first end of the second hinge structure 5 is hinged to the second keyboard body 2, and the second end of the second hinge structure 5 is hinged to the third keyboard body 3, so that the third keyboard body 3 can be folded relative to the second keyboard body 2.

[0059] As shown in Figure 4 and Figure 6 In one specific embodiment of the present application, the second hinge structure 5 comprises a first recess provided on the second keyboard body 2 and a second recess provided on the third keyboard body 3, a third rotating shaft 51 is arranged in the first recess, and a fourth rotating shaft 52 is arranged in the second recess.

[0060] The first hinge structure 4 further comprises a chain plate 53, the first end of the chain plate 53 is provided with a first through hole, and the second end of the chain plate 53 is provided with a second through hole; the third rotating shaft 51 is rotatably connected to the first through hole, and the fourth rotating shaft 52 is rotatably connected to the second through hole.

[0061] As shown in Figure 4 and Figure 6 In one specific embodiment of the present application, the number of second hinge structures 5 is at least two, and each second hinge structure 5 is arranged spaced apart from each other. Such a dispersed arrangement not only ensures the balance and stability of the second keyboard body 2 and the third keyboard body 3 during folding and unfolding, but also effectively avoids the risk of structural damage due to excessive force on a single point.

[0062] As shown in Figure 4As shown, in one specific embodiment of the present application, the first keyboard body 1, the second keyboard body 2 and the third keyboard body 3 are all provided with magnetic attraction members 6. When the foldable keyboard is in the folded state, the first keyboard body 1, the second keyboard body 2 and the third keyboard body 3 are magnetically attracted and adhered together by the magnetic force of the magnetic attraction members 6, which not only ensures the compactness and stability of the keyboard during carrying or storage, but also effectively avoids the loosening or damage of the keyboard caused by accidental collision or jolt.

[0063] In one specific embodiment of the present application, the third keyboard body 3 is further provided with a battery, which is electrically connected with the first function area keys 11, the second function area keys 21 and the touchpad 31 to provide electric energy for the first function area keys 11, the second function area keys 21 and the touchpad 31.
