[0025] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments. The implementation manners of the present utility model include but are not limited to the following embodiments.

[0026] The first embodiment:

[0027] As Figures 1-4 shown, the foldable keyboard base provided by the present utility model includes: a first base plate (101) and a second base plate 102. The first base plate 101 and the second base plate 102 are connected by a hinge. Sliding plates 103 are respectively provided at the lower ends of the first base plate 101 and the second base plate 102. The two sliding plates 103 have different functions. A touchpad is installed on the sliding plate 103 at the lower end of the first base plate 101, which is similar to the touchpad on a notebook, and the position of the mouse is controlled by moving the finger. The sliding plate 103 provided at the lower end of the second base plate 102 is the numeric function area of the keyboard. A chute 104 is provided at the lower end of the second base plate 102, and the setting direction of the chute 104 is consistent with the long axis direction of the first base plate 101 and the second base plate 102. Pulleys 105 are provided on both sides of the sliding plate 103 at the lower end of the second base plate 102, and the pulleys 105 are slidably installed in the chute 104 to realize the pulling of the sliding plate 103 at the lower end of the second base plate 102. Similar to the second base plate 102, a chute 104 is provided at the lower end of the first base plate 101, and pulleys 105 are provided on both sides of the sliding plate 103 at the lower end of the first base plate 101, and the pulleys 105 are slidably installed in the chute 104 to realize the pulling of the sliding plate 103 at the lower end of the first base plate 101. When in use, the first base plate 101 and the second base plate 102 stacked together are rotated and opened around the hinge, and then the left and right two sliding plates 103 are pulled outwards. When the keyboard is assembled, the above process corresponds to: after the first base plate 101 and the second base plate 102 are opened, the letter area of the keyboard is opened, and after the two sliding plates 103 are pulled out, the corresponding numeric area and touch area of the keyboard are pulled out from the lower end of the keyboard, and finally it is placed flat on the desktop for use.

[0028] The expansion of the keyboard function area is achieved by setting the sliding plate 103 at the lower ends of the first base plate 101 and the second base plate 102. Compared with the existing method of connecting different areas only through the folding function, this keyboard base plate only needs to be folded once to store the keyboard, and the gap between the two keyboard areas at the connection can be made smaller to meet the folding requirements.

[0029] Second Embodiment:

[0030] As Figures 4-5 shown, a slide rail 108 is provided at the lower end of the first base plate 101. The slide rail 108 is a quarter circle arc. A slider is provided on the sliding plate 103, and the slider slides in the slide rail 108. One corner of the sliding plate 103 at the lower end of the first base plate 101 is connected to the first base plate 101 through a rotating shaft perpendicular to the sliding plate 103. Therefore, the sliding plate 103 can slide 90° at the lower end of the first base plate 101.

[0031] By rotatably installing the sliding plate 103 at the lower end of the first base plate 101, the sliding plate 103 is located on the lower side of the first base plate 101 after being unfolded. A touchpad is installed at the upper end of the sliding plate 103, which is more convenient for the user to operate the touchpad relative to the left side position.

[0032] Third Embodiment:

[0033] As Figure 3 shown, a rubber pad 107 is provided at the lower end of the sliding plate 103. The rubber pad 107 can be glued to the lower end of the sliding plate 103. The sliding plate 103 is generally made of plastic or metal materials, and the friction coefficients of these two materials with the desktop are relatively small, especially for a relatively smooth desktop.

[0034] The rubber pad 107 is made of soft rubber material and has a relatively large friction coefficient with the desktop. When in contact with the desktop, it can prevent the sliding plate 103 from moving left and right on the desktop when the user is typing, thus maintaining stability.

[0035] Fourth Embodiment:

[0036] As Figure 3 shown, magnetic plates 106 are provided at the lower ends of the first base plate 101 and the second base plate 102. They are strip-shaped and installed between the first base plate 101 and the second base plate 102. One side of the sliding plate 103 close to the magnetic plate 106 has magnetism. For example, magnets can be pasted on the surfaces of the first base plate 101 and the second base plate 102. The magnetic plate 106 and the sliding plate 103 can attract each other. When the first base plate 101 or the second base plate 102 approaches the magnetic plate 106 at the lower end of the sliding plate 103, an attractive force is generated, causing the end of the sliding plate 103 to be adsorbed on the magnetic plate 106.

[0037] The adsorption and fixation effect on the first bottom plate 101 and the second bottom plate 102 is achieved by setting a magnetic plate 106 with magnetism, which can prevent sliding under external force when the keyboard is stored.

[0038] The fifth embodiment:

[0039] As Figure 6 shown, the sliding directions of the sliding plates 103 at the lower ends of the first bottom plate 101 and the second bottom plate 102 are perpendicular to each other. At this time, the structure of the sliding connection between the first bottom plate 101 and the sliding plate 103 at its lower end is the same as the structure for realizing the mutual sliding of the two in the first embodiment.

[0040] Working principle: Rotate and open the stacked first bottom plate 101 and the second bottom plate 102 around the hinge, and then pull the left and right sliding plates 103 outwards. When the keyboard is assembled, the above process corresponds to: after opening the first bottom plate 101 and the second bottom plate 102, the letter area of the keyboard is opened, and after pulling out the two sliding plates 103, the corresponding number area and touch area of the keyboard are pulled out from the lower end of the keyboard, and finally it is placed flat on the desktop for use.

[0041] The above embodiments are only one of the preferred embodiments of the present invention and should not be used to limit the protection scope of the present invention. Any meaningless changes or polish made in the main design concept and spirit of the present invention, as long as the technical problems solved are still the same as those of the present invention, should be included in the protection scope of the present invention.
