Problems solved by technology

[0002] At present, the ordinary keyboards used by people are bulky, not easy to carry, and need to use supports, such as desktops, etc.; the upper and lower sides of the three-dimensional keyboard (application number: 01138826.9 publication number: 1356622) have buttons, which can be held with both hands. Use, small size, easy to carry, but the arrangement of the keys on the main keyboard is not the usual arrangement of common keyboards, and the thumb-operated keys are only located on one side, and the user needs to pick up the keyboard to operate it. Those buttons cause great inconvenience like this, therefore, it is very necessary to develop a new keyboard that can be used in two modes, the front and the back, by combining the functions of the three-dimensional keyboard and the common keyboard, so as to solve the existing problems

Embodiment 1

[0011] Embodiment 1: the specific implementation manner of the present invention is as appended figure 1 , attached figure 2 , attached image 3 As shown, the keyboard is provided with a toggle switch, and the toggle switch is provided with two positions of "upper" state and "lower" state, respectively controlling and realizing two usage modes of the ordinary keyboard and the three-dimensional keyboard. When the main keyboard is to be used facing down, turn the toggle switch to the "down" position, and the characters represented by the keys on the main keyboard are arranged in a three-dimensional keyboard, as shown in the attached figure 2 As shown, at the same time, the keys on the thumb keyboard are valid. At this time, you can hold the two ends of the keyboard with both hands, operate the keys on the thumb keyboard with your thumb, and operate the keys other than the auxiliary keys on the main keyboard with the other fingers, and use the keyboard as a Use the three-dime...

Embodiment 2

[0012] Embodiment 2: the specific implementation manner of the present invention is as appended figure 1 , attached figure 2 , attached image 3 As shown, there is a push rod switch on the thumb keyboard. When the keyboard is placed on the support with the thumb keyboard facing down, the push rod of the push rod switch will be pushed into the keyboard due to the weight of the keyboard. At this time, it is " "Up" state, the main keyboard is facing upward, and the keyboard is used as a normal keyboard; when the keyboard is picked up, the push rod of the pusher switch pops up the keyboard, at this time it is in the "Down" state, the thumb keyboard is facing upward, and the keyboard is used as a three-dimensional keyboard use. Working principle is the same as embodiment 1.

Embodiment 3

[0013] Embodiment 3: the specific implementation manner of the present invention is as appended figure 1 , attached figure 2 , attached image 3 As shown, a toggle switch is set on the keyboard, and a push rod switch is set on the thumb keyboard surface. The toggle switch has three positions: "upper" state, "lower" state and "middle" state; when the toggle switch is in the "middle" state, the working mode of the keyboard is determined by the position of the push rod of the push rod switch. Control, the working principle is the same as that of embodiment 2; when the toggle switch is in the other two positions, the push rod switch does not work, and the working mode of the keyboard is controlled by the toggle switch, and the working principle is the same as that of embodiment 1.

[0014] In the above several embodiments, the layout of the main keyboard can be designed to rotate the thumb keyboard 180° horizontally to realize the conversion from a three-dimensional keyboard to...
