 Best embodiment

 The present invention will be further described below in conjunction with the drawings and specific embodiments.

 As shown in FIG. 3, it is an exploded view of the input keyboard structure of the present invention. It includes a touch panel 1, a touch sensor 2, a button holder 3, a metal shrapnel layer 4, and a circuit board (PCB) 5 from top to bottom. Among them, the tablet button 1 and the touch sensor 2 constitute a touch panel input keyboard, and the button holder 3, the metal dome layer 4 and the circuit board 5 constitute a mechanical button structure.

 As shown in FIG. 4, it is a sectional view of the input keyboard structure of the present invention. First, when the user touches the touch panel 1 with a pen or a finger, the point is sensed by the circuit on the touch sensor 2, and the function input is performed using professional software. Secondly, the touch panel 1 can be pressed down, and the metal dome 6 of the metal dome layer 4 is deformed by the elastic deformation of the button holder 3, especially through the contact 10 on the reverse side of the button holder 3, so as to make a circuit with the corresponding circuit board 5. The connection is made to conduct the circuit, and there is a two-stage feel.

As shown in FIG. 5, it is a schematic diagram of the explosion of the touchpad structure of the mobile phone of the present invention. Place The touch panel 1 is divided into upper and lower layers, the upper layer is made of PET material, the lower layer is a limiting film made of TPU material, and the upper layer is provided with a groove 7 so that the button forms a resilient arm, so that the button can be deformed. The ability to avoid the problem of partial depression of the button after repeated use, and the limiting film can increase the deformability of the PET, and has a limiting groove 8 on the limiting film, which can prevent the upper layer from sliding left and right or back and forth, the limiting film It can also absorb less pressure, avoiding the wrong signal on the mechanical button below, and it also has waterproof, dustproof, anti-static function, and of course can also protect the touch sensor.

 As shown in FIG. 6, it is a schematic diagram of the explosion of the button holder structure of the present invention. The button holder 3 has two sides on the front and back sides, and a groove 9 is formed on the front surface to form a resilient arm, which is more easily deformed. After the deformation, the metal dome 6 of the metal dome layer is pressed down by the contact 10 on the reverse side, and the metal dome 6 on the circuit board is pressed. The circuit connection realizes the conduction of the circuit; of course, due to the presence of the button holder, the small pressure at the time of implementing the touch function is absorbed, and the erroneous operation of the signal at the same time is avoided.

 4-6, the relationship between the groove 7 on the flat button 1 and the groove 9 on the button holder is correspondingly designed, and the size and shape of the groove 7 and the groove 9 can be set as needed, the contact 10 and The metal dome 6 is also of a corresponding design.

 The circuit parts of the touchpad input keyboard and the mechanical button structure are similar to the existing touchpad input keyboard circuit and mechanical keyboard circuit, respectively, except that their interfaces (or PIN pins) are on the same connector.

 As shown in FIG. 7, it is a schematic diagram of the function interface process of the present invention. First, the user can enter a specific function interface according to the default mode preset by the system, such as navigation, keyboard dialing, mouse operation, multimedia browsing, handwriting, etc., and then complete the function according to specific operations, if other functions are needed, Switching between function modes via software or hardware.

As shown in FIG. 8 and FIG. 9 , they are respectively a flow chart of implementing the navigation function of the present invention. And the operation diagram of the navigation function. The user's finger slides up, down, left, and right from the center of the touchpad, and the system reads the data of the first click position (posl) and the last hand raise position data ( Ps2); Then the system calculates the sliding direction based on the two points of data (posl, pos2), so that the four directions of the up, down, left, and right directions are generated. If the two points of data are the same, no motion command is generated; the system detects the metal dome of the central area. Whether it is pressed, if it is not pressed, continue to detect, otherwise the control software generates a "confirm" action command and the navigation is completed. The invention not only realizes the navigation function, but also realizes the one-hand operation by using the metal domes of the control and the touchpad in different layers to realize the confirmation action. For example, posl is (10,0). If pos2 is (70,30), the sliding tilt angle is close to the positive X axis, and the right direction is generated. If pos2 is (70,80), the sliding tilt angle is close to the positive direction. The y-axis produces an upward direction.

 Referring to Figures 10 and 11, respectively, they are a schematic diagram of the operation of the keyboard dialing of the present invention and a flow chart for realizing keyboard dialing and touch-by-touch navigation. A small block can be divided on the touch panel, and there are metal shrapnel under each cell block, and each cell block is set. These two functions can coexist at the same time, and are respectively introduced below.

 Making a call: Firstly, the system detects that the metal dome has been pressed, and then sends the corresponding digital number according to the number set by the location system of the pressed area, and the application software completes the dialing operation.

By-touch navigation: First, the system sets the navigation key area, and presets the direction of the navigation area. When the user touches the touchpad but does not press the metal dome, the software reads the position data of the hand lift time (pos ), send the corresponding direction command. For example, the area 2, 4, 6, 8, and 5 of the touch panel are set as the navigation area, and the 2, 4, 6, 8, and 5 areas are respectively set to the up, left, down, and right, "confirm" commands. When the user touches the corresponding area and lifts up, the system issues the corresponding direction command and confirms by pressing the "confirm" command. For example, when the system detects that the user touches the "2" area and lifts up in the area, On the command, and complete the navigation with the "5" confirmation command.

 By dialing the phone and by tapping the navigation, the two modes can coexist. When the hand is raised, the metal shrapnel is pressed to distinguish it. If pressed, the bay (J is the dialing mode, otherwise it is the navigation mode. The specific implementation process is as follows : In the first step, the system determines whether the metal dome is pressed, and if pressed, dials according to the number represented by the metal dome set by the system, and if not pressed, proceeds to the next step; Step, the system detects whether the user leaves the touchpad, if not, returns to the first step, otherwise proceeds to the next step; the third step, the system reads the current location data (pos), and then judges the current data according to the data Whether the location is in the navigation key area, if not, return to the first step, otherwise go to the next step; in the fourth step, the system issues a predetermined instruction according to the obtained data.

 In addition, the numeric keypad can expand symbols such as English letters, strokes and phonetic transcriptions. According to similar principles, the system can complete intelligent input in both Chinese and English, thus achieving one-handed Chinese and English intelligent input. The combination of the three can make the hardware part of the invention become a CCITT dialing keyboard which can be used for making telephone calls, Chinese-English intelligent input and touch-sensitive navigation (CCITT is the abbreviation of the International Telegraph and Telephone Consultative Committee, CCITT dial-up keyboard is The keyboard defined by the committee).

12 and 13, respectively, are respectively a flow chart and a mouse operation diagram of the mouse operation of the present invention. This function is similar to the mouse function of the current notebook computer. Firstly, the system establishes an association between the coordinates of the touchpad and the display screen. In the second step, when the user slides on the touchpad, the touchpad senses the sliding track, by the software. Get the specific coordinate position and display the position of the mouse on the display. Then the system detects whether the user leaves the touchpad. If it does not leave, repeat the second step. If it leaves, the system detects whether the metal dome is pressed. When pressed, the system obtains the coordinate data (pos) of the last stop position, and then the system detects whether a set button is pressed. If it is pressed, the left or right mouse button function can be implemented at the last stop position. Otherwise continue testing. The set button may be two cell blocks in the lower part of the touchpad, which respectively correspond to the left and right mouse buttons. Of course, the left and right mouse buttons may be associated with a metal dome or other mechanical mechanism at a specific position to implement the left and right button functions.

14 and 15 are respectively a schematic diagram of the multimedia browsing operation of the present invention and a schematic flowchart of the multimedia browsing of the present invention. This function enables multimedia quick browsing operations, such as quickly switching the cursor position, zooming in/out of text pictures, etc. in menu mode or space mode. The mode of operation is as follows: Slide the clockpad clockwise or counterclockwise. The specific implementation process is as follows: In the first step, when the touchpad is touched, the system obtains two data of unprocessed adjacent track positions; in the second step, the system calculates the sliding angle and the sliding direction according to the obtained data; In three steps, the system issues a predetermined command according to the sliding angle and the sliding direction, and implements a quick browsing operation according to the predetermined instruction; in the fourth step, the system detects whether all data of the sliding track is processed, and if not processed, returns to the first Step, otherwise, go to the next step; In the fifth step, the system detects whether the metal dome is pressed, and if it is pressed, the system generates a confirmation command, otherwise the detection continues. Firstly, the system senses the direction of rotation through the touchpad, and the driver software obtains the data of the trajectory. According to the data of the position of two adjacent points, the sliding angle and the direction are calculated, and the unit that issues the command is sent at a certain angle, and the direction of the browsing is issued in the direction. Commands, corresponding commands are issued according to the angle and direction, and the quick browsing operation is implemented on the application software. For example, when clockwise, when 20 degrees is used as the command unit, when the angle is 90 degrees, the driver software will round up and issue 4 clockwise commands. The function of multimedia browsing application software (switching cursor Position, text image enlargement/reduction, etc. will be processed according to this command. For example, in the enlargement/reduction function of the text image, clockwise represents zooming, and one command represents zooming in, then the above operation indicates the current operation. When the image is magnified four times, when the metal dome sensing in the center of the touchpad is pressed, the driver software issues a confirmation command, and the application software implements the corresponding function operation to complete the browsing function. The above is a separate explanation for each function. In fact, sometimes an application needs to use several functional modes at the same time. The way to deal with this is: when entering the application, the software will be based on one principle (for example, the most frequently used). Select one as the default function mode, and the user can switch when other functions are needed. The switching method can be implemented by hardware buttons or by software.

 Industrial applicability

 The invention puts a mechanical button with a hand into the touch panel button, so that it not only has a hand but also can realize touch and handwriting functions, and uses the metal dome in the introduced mechanical button to complete the navigation, mouse and multimedia browsing functions. Thereby achieving one-handed operation. The mechanical button structure added in the present invention is realized by the prior art, and the method for completing the navigation, mouse, and multimedia browsing functions is implemented on the basis of the existing mobile phone program, so the present invention has practical utility in the industry.
