Description

 FIELD OF THE INVENTION The present invention relates to the field of keyboard input technology, and more particularly to a face-shift keyboard. BACKGROUND OF THE INVENTION At present, a well-known keyboard device for inputting letters and symbols is a typewriter keyboard derived from the 17th century. The main principle is to arrange various 26 English letters, various symbols, control buttons and the like on the keyboard, and press the finger. Different buttons, trigger electronic or mechanical devices, provide letters or symbols for various human-computer interaction devices.

 Due to the development of technology, there are many devices that require letters and symbols to be input by the keyboard. Especially since the invention of the computer in the 1940s, the keyboard has been widely used as a main computer input device. However, the main disadvantages of the current keyboard are: The number of buttons is large, and the surface area of the keyboard is too large.

 The most basic letters and symbols that need to be entered by the keyboard are mainly divided into four categories, namely:

1, the letter. 26 English letters, 56 letters if case sensitive.

2. Arabic numerals. The number is 0-9 total.

 3. Symbols. 33 kinds of grammar and mathematical symbols.

 4, the control character. A total of 18 such as Enter, Del, Insert.

In addition, for the computer control, a total of 12 function keys F1-F12 are added to the computer keyboard. Since the keyboard keys are arranged in a plane, it is necessary to arrange so many buttons, and the required area is 4 inches. In order to reduce the number of buttons, the "upper key" method is currently used, so that some letters and symbol buttons share a button, such as using the "Caps Lock" button, so that the same uppercase and lowercase letters share a key; use the "Shift" button to make The 0-9 number and part of the symbol share a key.

 However, even with the "upper key" method, taking the computer keyboard as an example, the current standard keyboard is 101 keys, arranged on a plane, and the surface area of the keyboard cannot be reduced.

 The number of further buttons is too large, and the surface area of the keyboard is too large, causing two problems: 1. Seriously affecting input efficiency. Due to the large surface area of the keyboard and the large number of buttons, when the person inputs, the finger hangs on the keyboard up and down and left and right to find the button before the button can be pressed. The fatigue and input efficiency of the wrist when inputting with the keyboard has been an intractable problem. Although there are methods such as "ergonomic keyboard" to reduce wrist fatigue, there is no way to reduce the number of keyboard keys and the plane arrangement. The way of hand movement is not changed, and the problem is limited.

Second, it is not convenient to carry. Since many human-machine interactive electronic devices can achieve volume reduction through technological advancement, the main equipment of letters and symbols, since the keyboard has a large surface area, has not been miniaturized. Especially since the introduction of laptops and wearable computers, the keyboard has become the main "bottleneck" of these portable devices. SUMMARY OF THE INVENTION In view of this, the main object of the embodiments of the present invention is to provide a face-shifting keyboard, which can solve the problem that the keys on the keyboard are excessive and inconvenient to use. In order to achieve the above object, the technical solution of the embodiment of the present invention is implemented as follows: a face-shifting keyboard, wherein the keyboard includes: a fixed frame, one or more moving planes, and a plurality of buttons, wherein

 The fixing frame is a frame of a face-shifting keyboard, and the one or more moving planes are mounted on the fixing frame by a sliding rail, and the plurality of buttons are fixedly mounted on the moving plane; Enter characters and slide them to different positions according to the moving plane to change.

 The input characters corresponding to the multiple buttons are changed according to the moving plane to different positions, and the specific changes are as follows: the moving plane can slide on the slide rail to a preset plurality of positions, and slide to each preset In the position, the moving plane drives the connected sliding varistor or multi-contact switch, sends a corresponding signal to the control chip, and the signal triggered by the single button is sent to the control chip, and the control chip combines two signals according to a preset program. The character you want to enter.

 Wherein, the moving plane further sets the palm rest according to the positions of the plurality of buttons and the shape of the palm.

 The fixing frame is further provided with a prompting device for prompting the user to distinguish the moving plane from sliding to different positions.

 Wherein, between the slide rail and the moving plane, an elastic return device is further disposed.

 The moving plane of the face-shifting keyboard is set to one of left and right, and the preset program is programmed according to the layout of the existing keyboard.

An embodiment of the present invention provides a face-shifting keyboard, the keyboard, comprising: a fixed frame, one or more moving planes, and a plurality of buttons, wherein the fixed frame is a face-shifting keyboard a frame, the one or more moving planes are mounted on the fixed frame by the slide rails, and the plurality of buttons are fixedly mounted on the moving plane; the input characters corresponding to the plurality of buttons are slid to different positions according to the moving plane , make changes.

 FIG. 3 is a schematic diagram of a key position setting of the first embodiment of the face-moving keyboard of the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The basic idea of the present invention is to: mount a movable plane on a fixed frame, and install a button on a plane. When the plane moves to a different position, the button corresponds to inputting a different character.

 The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

 The embodiment of the present invention provides a face-shifting keyboard. FIG. 1 is a schematic structural diagram of a face-shifting keyboard according to the present invention. As shown in FIG. 1 , the keyboard includes: a fixed frame 11 and one or more moving planes. 12 and a plurality of buttons 13 , wherein

The fixing frame 11 is a frame of a face-shifting keyboard, and the one or more moving planes 12 are mounted on the fixing frame 11 by a sliding rail, and the plurality of buttons 13 are fixedly mounted on the moving plane 12; The input characters corresponding to the plurality of keys 13 are slid to different positions according to the movement plane 12, and are changed. Specifically, the input characters corresponding to the plurality of buttons 13 are changed according to the moving plane 12 to different positions, and the specific changes are: the moving plane 12 can slide on the slide rail to a preset plurality of positions, and slide to At each preset position, the moving plane 12 drives the connected sliding varistor or the multi-contact switch to send a corresponding signal to the control chip, and the signal triggered by the single button 13 is sent to the control chip, and the control chip is according to a preset program. Combine the two signals to determine the character you want to enter.

 Further, the moving plane 12 further defines a palm rest according to the position of the plurality of buttons 13 and the shape of the palm.

 The fixing frame 11 is further provided with a prompting device for prompting the user to distinguish the moving plane 12 from sliding to different positions. Specifically, the manner of prompting the user includes: prompting the user by mechanical or electronic means, moving the position where the plane 12 is now swiped; or sending the position information to the display screen for display.

 A resilient return device is also disposed between the slide rail and the moving plane 12. This allows the user to perceive the sliding direction of the moving plane 12, so that the user knows where the moving plane 12 is now, and also allows the user's palm to leave the moving plane 12, and the position can be accurately determined when the keyboard is used again.

 Further, the moving plane of the face-shifting keyboard is set to one of the left and the right, and the preset program is programmed according to the layout of the existing keyboard. This does not change the existing "QWERTY" character keyboard arrangement, but also enables the input of all characters.

 In summary, the main advantage of the face-shifting keyboard is that the function of "one button multi-purpose" is realized.

Further, in practical applications, the face-shift keyboard is divided into fixed frames and two left and right distributions. The three basic parts of the moving plane ("left moving plane" and "right moving plane"). The fixed frame does not move, and the two moving planes can move up and down through the slide rails mounted on the fixed frame, so that each moving plane forms three different positions (or more positions), that is, "up, down, and down" . A plurality of character buttons are fixedly mounted on each moving plane, and the character buttons move with the movement of the moving plane. In this way, each character button on the moving plane has three different positions (or more positions), so that each button can be arranged.

3 different characters (or more different characters), making 3 characters (or more characters) share a single button, so that the original keyboard is arranged in a row of 3 rows (or more rows) of characters Press the button to change to 1 row, reducing the number of buttons. The upper and lower ends of the moving plane are connected to the keyboard fixing frame by springs, so that the left and right moving planes can be returned in time. There is a palm rest on each moving plane. When inputting, the left and right palms are attached to the palm rest of the moving plane. The palm rest is used to move the left and right moving plane up and down. Due to the pulling force of the spring, the left and right hands can clearly feel. Up, down, down, three different positions. The buttons on the moving plane are distributed according to the shape of the left and right fingers. Thus, when the characters are input, only the palms move down, and the fingers can be fixed on each moving plane. On the button, the wrist has to rely on and not hang. The original keyboard input is hand-hanging on the keyboard to move up and down, and the technical method is to change the palm to the moving plane, and move the moving plane up and down. The range of movement can be adjusted very much. Small, and the key arrangement can refer to the arrangement of the original keyboard, so the movement of the hand when the character is input can be greatly reduced, and the arrangement of the keys does not change greatly, and the input habit of using the traditional keyboard can be taken into consideration, thereby improving The keyboard character input efficiency. In particular, since the finger is basically fixed on the button, the traditional keyboard operates "" Play "technology easier to implement. Since one key is 3 or more characters combined use, each key It is obviously unrealistic to print 3 characters on the keyboard, and the finger is basically fixed on the button, and the character symbol represented on the button cannot be seen. Therefore, the "face-shifting keyboard" has three basic parts except the fixed frame and the left and right moving plane. The letter or symbol represented by the current position character button is displayed mechanically or electronically.

 2 is a schematic structural view of the first embodiment of the face-moving keyboard of the present invention, wherein the left moving plane (23) is connected to the keyboard fixing frame (21) through two sliding rails (26) to realize up-and-down movement. The right moving plane (24) moves up and down in the same way. When inputting, the left and right palms are placed on the left palm rest (219) and the right palm rest (229), and the left and right ten fingers are placed on the left-hand composite button (217) and the right-hand composite button (227) and the right shift. The plane (24) moves up and down, so that the finger is basically fixed on the left-hand composite button (217) and the right-hand composite button (227) on the keyboard. Since the middle spring (28) is attached to the keyboard fixing frame (21) at the four corners of the left and right moving planes, the left and right hands can clearly feel the "up", "middle", and "left" movement planes under the elastic force. Under "three different positions. The left and right moving planes are respectively provided with sliding rheostats (215) (225) or multi-contact switches, so that the left and right moving planes generate different resistances in the "up", "middle", and "down" positions, which are used for keyboard circuit recognition to generate different symbols. . Since the left-hand composite button (217) and the right-hand composite button (227) output different characters according to different positions of the left and right moving planes, each of the current is displayed by the left-hand composite button display (213) and the right-hand composite button display (223), respectively. The character represented by the composite button.

FIG. 3 is a schematic diagram of key position setting of the first embodiment of the face shifting keyboard of the present invention. Five left-hand composite buttons are installed on the left moving plane. These five buttons are named as: KL1, KL2. KL3, KL4, KL5. Install 5 right-hand composite buttons on the right moving plane. These five buttons are named: KR1, KR2, KR3, KR4, KR5. A total of 10 composite buttons, combined with the "up", "middle" and "down" positions of the moving plane, can have 10 * 3 = 30 different combinations, so it can be used as the main button for keyboard input, for 26 The input of English letters and Arabic numerals, various symbols. In order to input all the letters, numbers and symbols with these 10 buttons, the face-shift keyboard also has a case, number, symbol switch button, and the composite button key arrangement is arranged.

 When the Caps Lock, Num Lock, and Symbol Lock toggle buttons are off, the composite button is used for 26 lowercase English letters. In the key arrangement, since the arrangement of the "QWERTY" keyboard keys has been formed, the present invention does not intend to change the original keyboard key arrangement, and the lowercase English alphabet key table formed by the position of the keys and the moving plane can be arranged as a table. 1 :

 Table 1

Since the above basic English alphabet key arrangement is consistent with the current "QWERTY" keyboard, it conforms to the current popular keyboard typing technique, and it is only the original hand hanging up and down to change to the palm to move, so it is easy to promote. In addition, due to TAB (tabulation key) And Space (spacebar) is a common editing key, so it is arranged in the English alphabet basic key table. Space (empty 4 built) is used more, so two buttons are arranged, corresponding to the thumbs of the left and right hands. The English hyphen "-" is also often used in English input, so it is also programmed into the basic English alphabet keys.

 When Caps Lock is closed, the composite button is used for 26 uppercase English letters. The uppercase English alphabet key arrangement is still as shown in Table 1.

 When Num Lock is closed, the composite button is used for the input of 10 Arabic numerals and some commonly used symbols. Since the number of symbols exceeds 30 and the number of Arabic numerals is only 10, some symbols are placed in the Num Lock ON state input. The number and partial symbol key arrangements are as shown in Table 2:

 Table 2

 In the key arrangement of Table 2 above, since the current keyboard, some symbols and numeric keys are shared by "Shir (upper key), this is also a compound habit. In addition, numbers and decimal points, commas, plus and minus, Inputs greater than less than or equal to are closely related, so these symbols are also placed in the digital input state.

键 键 键 键 键 键 键 键 When the Symbol Lock is closed, the composite button is used for the input of other symbols. The key position is as shown in Table 3:

Key key key

"Up" position ~ { } I ( )

"中" position [ ] \ , 1

 "Bottom" position < > Space Space + - = Table 3 The above three tables completely complete all the letters, numbers and symbols on the existing keyboard, and can be input by the left and right hand composite buttons. In addition, other control keys (such as the direction key, enter key, delete key, cancel key, etc.) are arranged on the keyboard fixed frame. See Figure 2 for the specific arrangement. The face-shifting character keyboard has a total of 32 buttons, which fully realizes all the functions of the popular computer 101 keyboard, which can greatly reduce the keyboard area. Of course, in theory, if the position of the moving plane exceeds 3 or more, other control keys can be completely replaced by 10 composite keys, so that the total number of key positions is less than a dozen, which can greatly reduce the keyboard area. Can be used on the keyboard of a portable device. The above is only the preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included. Within the scope of protection of the present invention.
