Description

Technical Field

[0001] This invention relates to the field of electronic input device technology, specifically to a folder-integrated fitness electronic input keyboard, which is particularly suitable for portable electronic input devices that combine exercise interaction and text input. Background Technology

[0002] Patent No. 2025105695861 (hereinafter referred to as D1) discloses a method patent for an interactive response method, which adopts nine input terminals arranged in a centripetal trend. The arrangement of these nine input terminals is conducive to the user triggering the input terminals within the shortest distance and also makes it easy for the user to remember the position of each input terminal. It is suitable for interactive scenarios of educational software and also meets the usage needs of electronic punching target and sports keyboards.

[0003] However, the electronic punching bag-type sports keyboard involved in D1 has obvious defects: the overall thickness and size of the device are large, it cannot be folded and stored, and it is not convenient to put it in a backpack for carrying around, making it difficult to meet the user's need for use anytime and anywhere; at the same time, the bottom plate of the existing folder-type carrier is evenly divided into two halves by a bent structure. If the nine input terminals of D1 are directly applied to the existing folder structure, while ensuring that the area of ​​each input terminal is maximized and the size is uniform, and the arrangement of D1 is maintained, only 6 input terminals can be located on one half of the bottom plate of the folder, and the other 3 input terminals are located on the other half of the bottom plate. This results in an uneven distribution of the number of input terminals on the two halves of the bottom plate, and it is impossible to maximize the trigger area and / or the distance between the center points of the nine input terminals.

[0004] In sports scenarios such as boxing, palm strikes, and hand touches, users need to move their arms, which involves a large range of motion and a large contact area. If the contact area and / or the distance between the center points of the nine input terminals are too small, it will not only fail to meet the needs of such a large range of motion, but will also easily lead to accidental touches, affecting the user experience and input accuracy.

[0005] Furthermore, existing folding keyboards are designed solely to improve portability, without structural adaptation for motion input scenarios with large contact areas; existing folder-style stands only provide support and storage functions, lacking electronic input-related structures and functions; existing technologies simply add input points, merely expanding input functions and increasing the number of keys, without any technical purpose of structural adaptation and area optimization, and none of them solve the technical problem of the contradiction between "portable folder storage" and "motion input with large contact areas". Summary of the Invention

[0006] To address the shortcomings of existing technologies, the present invention aims to provide a folder-integrated fitness electronic input keyboard, solving the problems of existing sports electronic input keyboards being inconvenient to carry and the folder carrier being unable to accommodate the uniform distribution of large contact area input terminals. The device can be folded and stored in a backpack for easy carrying, and can be placed on a desktop or fixed to a wall as a punching bag. At the same time, it maximizes the trigger area and / or the distance between the center points of the nine input terminals, adapting to the input needs of large-range sports such as boxing and palm strikes, and providing an integrated input device that can be used for sports and learning anytime and anywhere.

[0007] Technical solution To achieve the above objectives, the present invention adopts the following technical solution: like Figure 1 , Figure 2 , Figure 3 As shown (corresponding to claims 1 and 5): A folder-integrated fitness electronic input keyboard that can maximize the input end area includes a keyboard body with multiple input ends. The keyboard body includes a base plate (10) and a thin film (100) covering the base plate. The bonding surfaces (7) of the base plate (10) and the thin film (100) are both attached with conductive lines. The conductive lines include block contact lines (5) attached to the base plate (10) and block contact lines (55) attached to the thin film (100). By external pressing, the block contact lines (5) and block contact lines (55) corresponding to the same input end can be made to contact and conduct.

[0008] The keyboard body is folded through a crease area (85), which is a foldable area composed of one or more creases in the same direction. Some input terminals and their corresponding block contact lines (5) and block contact lines (55) are divided into two block contact lines by the crease area (85), so that their corresponding input terminals are divided into two halves and can be folded.

[0009] The conductive lines also include connecting lines (80) for electrically connecting each block contact line and leading it to the signal receiving end of the keyboard main control module (11). The arrangement of the connecting lines (80) is such that the block contact line (5) and block contact line (55) corresponding to each input end can respectively correspond to a unique combination of row connection ends and column connection ends of the signal receiving end of the keyboard main control module (11). The pair of block contact lines (5) and pair of block contact lines (55) corresponding to each input end that is evenly divided by the crease area (85) can also be connected to a unique combination of row connection ends and column connection ends of the signal receiving end of the keyboard main control module (11) corresponding to its corresponding unique input end through the connecting lines (80).

[0010] The keyboard body of the present invention preferably has nine input terminals, which are arranged in a pattern of eight input terminals surrounding a central input terminal (950). The nine input terminals are respectively the upper left input terminal (910), the upper center input terminal (920), the upper right input terminal (930), the left center input terminal (940), the center input terminal (950), the right center input terminal (960), the lower left input terminal (970), the lower center input terminal (980), and the lower right input terminal (990). The nine input terminals are evenly distributed by the crease area (85) and satisfy one of the following two distribution methods: Method 1: For example Figure 1 , Figure 3 As shown, the top input terminal (920), the center input terminal (950), and the bottom input terminal (980) are all divided into left and right halves. When the left and right halves of the top input terminal (920) are pressed, they both activate the combination of the unique row connection terminal and column connection terminal corresponding to the top input terminal (920). When the left and right halves of the center input terminal (950) are pressed, they both activate the combination of the unique row connection terminal and column connection terminal corresponding to the center input terminal (950). When the left and right halves of the bottom input terminal (980) are pressed, they both activate the combination of the unique row connection terminal and column connection terminal corresponding to the bottom input terminal (980). This method is suitable for folders whose overall width is greater than their height when opened in the left and right direction.

[0011] Method 2: For example Figure 2 As shown, the left input terminal (940), the center input terminal (950), and the right input terminal (960) are all divided into upper and lower halves. When the upper and lower halves of the left input terminal (940) are pressed, the combination of the unique row connection terminal and column connection terminal corresponding to the left input terminal (940) is activated. When the upper and lower halves of the center input terminal (950) are pressed, the combination of the unique row connection terminal and column connection terminal corresponding to the center input terminal (950) is activated. When the upper and lower halves of the right input terminal (960) are pressed, the combination of the unique row connection terminal and column connection terminal corresponding to the right input terminal (960) is activated. This second method is suitable for folders whose overall width is greater than their height when opened in the vertical direction.

[0012] In the equal distribution setting, the two parts of each equally distributed input terminal are located on both sides of the crease area (85). Through this equal distribution setting, the nine input terminals are evenly distributed in the keyboard theme, with each side occupying half of the physical area of ​​the nine input terminals, that is, 3 complete input terminals + 3 half input terminals, which is equivalent to the area ratio of 4.5 input terminals. This maximizes the trigger area of ​​the input terminals and / or the distance between the center points. The area of ​​a single block contact line (5) or block contact line (55) is 25 to 120 square centimeters, and the distance between each block contact line (5) or block contact line (55) based on the center point of its block contact line is 8 to 18 centimeters; when the foldable area composed of multiple folds in the same direction is used, the fold width of the fold area (85) is less than 5 centimeters; the folded area (85) is divided into two block contact lines, each with an area of ​​7 to 60 square centimeters, so that the corresponding input end is divided into two halves and can be folded, which is suitable for the large contact area requirements of boxing and palm strike sports.

[0013] Furthermore, the integrated folder-type fitness electronic input keyboard also includes a leftmost input terminal (61) and a rightmost input terminal (62) (corresponding to claim 6); the leftmost input terminal (61) is located on the left outer side of the entire nine input terminals; the rightmost input terminal (62) is located on the right outer side of the entire nine input terminals; and satisfies one of the following two electrical connection methods: Method 1: The block lines corresponding to the leftmost input terminal (61) and the rightmost input terminal (62) are respectively electrically connected to a unique combination of row connection terminals and column connection terminals in the signal receiving terminal of the keyboard main control module (11) through the connecting line (80), and the two combinations are not repeated with the combinations of row connection terminals and column connection terminals corresponding to the above nine input terminals, so as to realize the independent input function of different input terminals; In a more preferred embodiment, the leftmost input terminal (61): C4, R1; the rightmost input terminal (62): C4, R2.

[0014] Method 2: The block lines corresponding to the leftmost input terminal (61) and the rightmost input terminal (62) are electrically connected to the same unique combination of row connection terminal and column connection terminal in the signal receiving terminal of the keyboard main control module (11) through the connecting line (80) (as with connecting C4 and R1), and the combination of row connection terminal and column connection terminal corresponding to the above nine input terminals is not repeated, so as to realize the independent input function of the leftmost input terminal (61) and the rightmost input terminal (62) as the same input terminal.

[0015] The leftmost input terminal (61) and the rightmost input terminal (62) are used to adapt to the striking actions on the left and right sides of the human body. Their structure is consistent with the nine input terminals, realizing large-area contact triggering and adapting to the needs of boxing and palm strike sports.

[0016] Furthermore, the keyboard body only satisfies the following feature A and / or the following feature B (corresponding to claim 2): Feature A: An insulating film (83) is provided between the mating surfaces of the base plate (10) and the film (100); the insulating film (83) has multiple holes / notches (81), the number, size, shape and position of the holes / notches (81) correspond one-to-one with each set of mutually cooperating block contact lines (5) and block contact lines (55), the shape of the holes / notches (81) is circular and the size matches the size of the block contact lines, so that when pressed, the corresponding two sets of block contact lines pass through the holes (81) to achieve electrical connection.

[0017] Feature B: The surface of the connecting line (80) is provided with an insulating coating or insulating film, and the insulating layer material is UV insulating ink.

[0018] In the keyboard body of feature A or feature B, in each set of mutually cooperating block contact lines (5) and block contact lines (55), at least one block contact line is provided with multiple insulating protrusions (82). The number of insulating protrusions (82) is 4 to 8, and they are evenly distributed at intervals of 0.1 cm to 2 cm from the block contact lines. The material is UV insulating ink. After UV insulating ink is cured, its hardness is ≥3H and its impact resistance is ≥10J / cm². It can withstand the impact of punches and palm strikes without falling off. The height of the insulating protrusions (82) is 0.2-0.5 mm and the diameter is 2-5 mm. They are evenly distributed along the edge of the block contact lines at intervals of 0.5-1 cm to prevent accidental contact and conduction when not pressed.

[0019] Furthermore, such as Figure 1 , Figure 2 , Figure 3As shown, the surface of each input terminal is marked with a corresponding position mark (9) (corresponding to claim 3). The position mark (9) is located on the surface (8) of the thin film (100) facing away from the bottom plate surface (10), and the block contact circuits (5) and block contact circuits (55) corresponding to each input terminal correspond one-to-one with the position of the position mark (9), enabling the user to accurately trigger the corresponding input terminal according to the position mark (9). In a specific embodiment, the specific form of the position mark (9) is a circular contour, and the character symbol areas (13) of each input terminal are specifically as follows: for the upper left input terminal (910), it is not only marked with the numbers 1 and 0 but also includes the character "Fu" representing all punctuation marks and spaces; for the directly above input terminal (920), it is marked with the three phonetic letters a, b, c and the number 2; for the upper right input terminal (930), it is marked with the three phonetic letters d, e, f and the number 3; for the directly left input terminal (940), it is marked with the three phonetic letters g, h, i and the number 4; for the directly middle input terminal (950), it is marked with the three phonetic letters j, k, l and the number 5; for the directly right input terminal (960), it is marked with the three phonetic letters m, n, o and the number 6; for the lower left input terminal (970), it is marked with the four phonetic letters p, q, r, s and the number 7; for the directly below input terminal (980), it is marked with the three phonetic letters t, u, v and the number 8; for the lower right input terminal (990), it is marked with the four phonetic letters w, x, y, z and the number 9; for the leftmost input terminal (61), it is marked with a left arrow; for the rightmost input terminal (62), it is marked with a right arrow.

[0020] Further, the keyboard main control module (11) includes a signal receiving unit, a signal recognition unit, a signal conversion unit, and a communication unit (corresponding to claim 7), where: the signal receiving unit is a matrix key scanning circuit or its equivalent replacement structure (i.e., a structure with the same function and capable of achieving the same technical effect, including but not limited to a key scanning circuit), and is used to receive the conduction signals of each input terminal; the signal recognition unit is a single-chip microcomputer, and is used to recognize the combination of the row connection terminal and the column connection terminal corresponding to the conduction signal; the signal conversion unit is a key value mapping module, and is used to convert the recognized row-column combination into an input instruction recognizable by a computer; the communication unit is a Bluetooth chip or a USB controller or its equivalent replacement communication module (including but not limited to a radio frequency chip, a WiFi module, etc., a module capable of communicating with a computer or a mobile device), and is used to implement communication with devices such as a computer and a mobile phone.

[0021] The keyboard main control module (11) further includes the following feature C and / or feature D: Feature C: The keyboard main control module (11) is provided with a USB socket, and the USB socket supports OTG connection to a mobile phone, facilitating the user to directly insert it into the mobile phone through an OTG adapter data cable for use when the battery of the keyboard main control module (11) is out of power; Feature D: The keyboard main control module (11) includes a Bluetooth function module and a battery module to realize wireless communication and independent power supply.

[0022] The preferred combination of unique row and column connectors for each input terminal is as follows: Top left input terminal (910): C1, R1; Top input terminal (920): C2, R1; Top right input terminal (930): C3, R1; Left input terminal (940): C1, R2; Center input terminal (950): C2, R2; Right input terminal (960): C3, R2; Bottom left input terminal (970): C1, R3; Bottom input terminal (980): C2, R3; Bottom right input terminal (990): C3, R3. The above combination of row and column connectors is only a preferred solution and can be adjusted according to actual design requirements.

[0023] Each connection line (80) used to connect the row connection end or the column connection end has a terminal (300) that is soldered or bonded together with conductive adhesive at the end. The terminal (300) is a copper sheet. Each terminal (300) is soldered with a signal extension line (6) that is electrically connected to the row connection end and the column connection end of the signal receiving end of the keyboard main control module (11). The signal extension line (6) is covered with insulating rubber, and all extension lines are wrapped in insulating rubber. The material of the extension line (6) is a data cable and the length is 10 cm to 30 cm. The terminals attached to the bottom plate surface (10) are all concentrated in the same area near the crease area (85) at the top of the bottom plate surface (10). The terminals attached to the film (100) are all concentrated in the same area near the crease area (85) at the top of the film (100). The two areas are the same area.

[0024] Furthermore, such as Figure 1 , Figure 2 As shown, the integrated folder-type fitness electronic input keyboard is also provided with an expansion interface (6130) and an expansion interface (6140) (corresponding to claim 8); the connecting lines (80) of the block contact line (5) and the block contact line (55) corresponding to the leftmost input terminal (61) are both connected to the expansion interface (6130); the connecting lines (80) of the block contact line (5) and the block contact line (55) corresponding to the rightmost input terminal (62) are both connected to the expansion interface (6140); The expansion interface (6130) and expansion interface (6140) can be used to achieve a detachable electrical connection with an external auxiliary input terminal. The detachable electrical connection includes plug-in connection, snap-on connection, magnetic connection or equivalent replacement form (including but not limited to threaded connection, spring contact connection, etc., which can achieve a detachable electrical conduction connection structure). In a specific embodiment, the expansion interface is a plug-in CD adapter, wherein the block contact line corresponding to the leftmost input terminal (61) and the rightmost input terminal (62) is the CD adapter female connector.

[0025] The specific connection method is as follows: the block contact line (5) corresponding to the leftmost input terminal (61) is connected to a connecting line (80) extending to the leftmost side of the bottom plate surface (10). The end of each connecting line (80) has a terminal (300) that is electrically connected by welding or conductive adhesive. The terminal (300) is a copper sheet, and the positive wire of the CD adapter is welded to the terminal (300). The block contact line (55) corresponding to the leftmost input terminal (61) is connected to a connecting line (80) extending to the leftmost side of the mating surface (7). The end of each connecting line (80) has a terminal (300) that is electrically connected by welding or conductive adhesive. The terminal (300) is a copper sheet, and the negative wire of the CD adapter is welded to the terminal (300). 0) On; the block contact line (5) corresponding to the rightmost input terminal (62) is connected to a connecting line (80) extending to the rightmost side of the bottom plate surface (10). The end of the connecting line (80) has a power terminal (300) that is electrically connected by welding or conductive adhesive. The power terminal (300) is a copper sheet. The positive wire of the CD adapter is welded to the power terminal (300). The block contact line (55) corresponding to the rightmost input terminal (62) is connected to a connecting line (80) extending to the rightmost side of the mating surface (7). The end of the connecting line (80) has a power terminal (300) that is electrically connected by welding or conductive adhesive. The power terminal (300) is a copper sheet. The negative wire of the CD adapter is welded to the power terminal (300).

[0026] Furthermore, such as Figure 3 As shown, the external auxiliary input terminals are a left foot pedal input terminal (6100) and a right foot pedal input terminal (6200) (corresponding to claim 9); the left foot pedal input terminal (6100) is electrically connected to an expansion interface (6111) via a signal line (51), and the right foot pedal input terminal (6200) is electrically connected to an expansion interface (6211) via a signal line (52); the expansion interfaces (6111) and (6211) are both male CD adapter connectors.

[0027] The expansion interface (6111) can be connected to the expansion interface (6130). After connection, pressing the left foot pedal input terminal (6100) can connect the expansion interface (6111) and (6130) to make the block contact line (5) and block contact line (55) corresponding to the leftmost input terminal (61) conduct. The combination of the connected row connection terminal and column connection terminal is consistent with directly pressing the leftmost input terminal (61). After releasing, it returns to the non-electrical conduction state. The expansion interface (6211) can be connected to the expansion interface (6140). After connection, pressing the right foot pedal input terminal (6200) will connect the expansion interface (6211) and (6140) to make the block contact line (5) and block contact line (55) corresponding to the rightmost input terminal (62) conductive. The combination of the conductive row connection terminal and column connection terminal is consistent with directly pressing the rightmost input terminal (62). After releasing, it returns to the non-electrical conductive state. The signal lines (51) and (52) are both dual-core signal lines. The two cores are electrically connected to the positive and negative terminals of the CD adapter. The signal lines are made of flexible copper wire, with a single-core copper wire diameter of 0.1 to 1 mm. They are covered with an outer insulating rubber layer with a thickness of 1 mm to 1 cm and a length of 1.2 m to 2 m. The specific structure of the foot pedal input terminal is as follows: a circular foot pad with a diameter of 20 cm, with a membrane switch inside. The positive and negative terminals of the membrane switch are respectively connected to a single core of the dual-core signal line (51) and (52). The pressing trigger force is 5-10N, which is suitable for foot pedaling action. The membrane switch is built-in to realize the connection and disconnection function of its unique row and column receiver. The membrane switch is wrapped with wear-resistant rubber. The trigger surface of the left foot pedal input terminal (6100) is marked with the word "left". The trigger surface of the right foot pedal input terminal (6200) is marked with the word "right". The leftmost input terminal (61) and the rightmost input terminal (62) are used to mimic the striking motions of the left and right sides of the human body, while the left / right foot pedal input terminal can make people mimic the left and right jumping motions. The two are just different in terms of the motion method. Pressing the foot pedal input terminal can make the block contact circuit of the leftmost / rightmost input terminal conduct, so that the row connection terminal and column connection terminal connected by pressing the left foot pedal input terminal and striking the left input terminal (61) are the same, and the row connection terminal and column connection terminal connected by pressing the right foot pedal input terminal and striking the right input terminal (62) are the same. Therefore, users can choose the left and right striking motions or the left and right jumping motions according to their own exercise preferences to input the same instructions to the computer, giving users the space to freely choose the exercise method.

[0028] Furthermore, such as Figure 1 , Figure 2As shown, the block-shaped contact lines and connecting lines (80) attached to the base plate (10) and the film (100) are all conductive lines formed by printed lines, conductive tape, or equivalent alternatives (corresponding to claim 10), including but not limited to conductive ink lines, flexible copper foil lines, metal wire welding lines, etc., which are conductive structures capable of transmitting electrical signals; wherein, the printed lines are printed with conductive silver paste on the base plate and the film using screen printing technology, with a thickness of 0.1-0.5mm; the conductive tape is made of copper foil conductive tape, which is attached to the base plate and the film by pressure-sensitive adhesive, and the width of the conductive tape is 5-10mm; the equivalent conductive ink lines are printed with conductive ink on the base plate using screen printing technology, with a thickness of 0.1-0.3mm; the connecting lines across the crease area are made of flexible copper foil, and a redundant length, such as 1-2cm, is reserved at the bend to avoid the lines breaking when folded.

[0029] Furthermore, the input end is integrated into the bottom plate (10) of the folder (1). The folder can be folded and stored, carried in a backpack, and used on a desktop or fixed on a wall as a punching bag. The trigger area and / or the distance between the center points of the input end are maximized, with a maximum of 150 square centimeters per end, which is suitable for large-scale sports movements such as boxing and palm strikes. The size of the folder that a regular backpack can hold is 30cm×45cm, with a total area of ​​1350 square centimeters. After the bottom plate is divided into folded areas, the area on each side is 675 square centimeters. Each of the 4.5 input ends can occupy a maximum of 150 square centimeters on average. This size can meet the large contact area requirements of boxing and palm strikes. The palm area of ​​an adult is about 100-150 square centimeters.

[0030] Beneficial effects Compared with the prior art, the present invention has the following beneficial effects: 1. By evenly distributing a portion of the input terminals across the folded area (technical feature), the area ratio of the input terminals on both sides of the folder is made consistent. Combined with the size and spacing design of the block-shaped contact lines, the trigger area of ​​the input terminals and / or the distance between the center points is maximized (beneficial effect). The maximum area of ​​a single terminal can reach 150 square centimeters, matching the area of ​​an adult's palm. This solves the problem in existing technologies where the number of input terminals cannot be evenly distributed in a small-area folded keyboard body (e.g., it cannot be evenly distributed into 9), thus making it impossible to maximize the input terminal area while minimizing the keyboard body. This is because an excessively small input terminal area cannot accommodate boxing or palm strikes, which are large-range movements, and would increase the probability of accidental touches by users. On the other hand, an excessively large keyboard body would be inconvenient to carry in a backpack (problems to be solved). 2. Through the integrated folder structure design (technical feature), the input end is integrated into the bottom plate of the folder. The folder can be folded and stored through the crease area, and can be put into a regular backpack for easy carrying. When in use, it can be placed on a desktop or fixed to a wall as a punching bag, realizing the combination of portability and sports input function, and providing an input device for sports learning anytime and anywhere (technical effect). 3. By expanding the design of the interface and foot pedal input terminal (technical feature), the input commands for striking and foot pedal bouncing actions can be interconnected. Users can choose the input method according to their own sports preferences, enriching the forms of sports input and improving the flexibility of use (technical effect). 4. By combining matrix key recognition with membrane switch structure (technical feature), and incorporating anti-misoperation structural designs such as insulating protrusions, insulating coatings, and insulating films, it effectively prevents accidental contact and conduction when not pressed, ensuring independent recognition of signals at each input terminal and improving input accuracy; at the same time, the circuit material and process are adapted to the folder folding requirements, and the circuit across the fold area is reserved with redundancy to avoid circuit breakage when folded and extend the service life of the device (technical effect). 5. The design of location markers and character symbols (technical features) makes it easy for users to quickly remember and accurately trigger each input terminal, taking into account the dual needs of motion interaction and text input, and adapting to multiple application scenarios such as education and sports (technical effects). 6. Through the multi-communication method and OTG function design of the keyboard main control module (technical feature), it supports multiple communication methods such as Bluetooth and USB, and can connect to various devices such as computers and mobile phones. Moreover, the OTG function can be used directly when the battery is dead, improving the device's compatibility and emergency use capability (technical effect). 7. By setting the leftmost and rightmost input terminals and two electrical connection methods (technical features), it can flexibly adapt to the needs of different motion scenarios, either to achieve independent input or collaborative input, further improving the practicality of the device (technical effect). 8. Through various adaptation methods of conductive lines (technical features), the appropriate line type can be selected according to actual production needs, reducing production difficulty and cost, while ensuring the stability of electrical signal transmission and the service life of the line (technical effect).

[0031] Creative explanation 1. The existing technology does not have a technical solution of using a base plate (10) and a thin film (100) as the keyboard body + an input end structure composed of evenly divided block lines in the crease area + a combination of matching row connection ends and column connection ends to the evenly divided block lines. Therefore, it cannot achieve the ultra-thin structure effect of the present invention and the beneficial effect of maximizing the effective trigger area of ​​the input end by evenly dividing the small area keyboard body into 9 input ends adapted to the size of boxing. Therefore, it cannot achieve the technical effect of the ultra-thin folder 9-key punching target in the present invention. 2. When faced with the technical requirement of "folder carrying + large contact area motion input", those skilled in the art would typically reduce the number of input terminals or shrink the area of ​​the input terminals. This is because there is no technical solution in the prior art that allows the user to simultaneously strike the two equally divided input terminals with a single punch, based on the size of the fist's force area, thereby increasing the trigger area of ​​the user's fist while achieving a foldable function. Therefore, the equally divided structure of the present invention is not obvious.

[0032] 3. The essential difference between this invention and the prior art is that it solves the contradiction between "the portability of a small-area, center-foldable keyboard body" and "maximizing the trigger area of ​​multiple large-contact input terminals that cannot be evenly divided by the center line" to simultaneously maximize the beneficial effects. This is a technical problem that has not appeared in the prior art. Attached Figure Description

Detailed Implementation

[0034] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.

[0035] Example 1 like Figure 1 As shown, this embodiment is the folder-integrated fitness electronic input keyboard of claim 1. The crease area (85) is a crease line. The unfolded size of the folder is 30cm×45cm. The input end (920) at the top, the input end (950) at the center, and the input end (980) at the bottom are all divided into left and right halves by the crease area (85). Each half is located on both sides of the crease area (85).

[0036] The input terminal adopts a membrane switch structure. The bottom plate (10) and the membrane (100) bonding surface (7) are printed with conductive silver paste through screen printing to form a block contact line and a connecting line with a thickness of 0.3mm. The structure design of feature A is adopted, with an insulating film (83) placed between the two, and a circular hole (81) is opened on it, the size of which matches the block contact line. Four to eight insulating protrusions (82) are set on the block contact line. The material is UV insulating ink, with a height of 0.3mm and a diameter of 3mm. They are evenly arranged at intervals of 0.8cm along the edge of the block contact line. After curing, the UV insulating ink has a hardness of 3H and an impact resistance of 12J / cm².

[0037] The power terminal (300) at the end of the connecting line (80) is a copper sheet, which is concentrated in the same area on the bottom plate and above the film near the spine. It is connected to the keyboard main control module (11) through a 20cm long signal extension line (6). The keyboard main control module (11) uses a microcontroller as the signal recognition unit, a matrix key scanning circuit as the signal receiving unit, a Bluetooth chip and a USB controller as the communication unit, a USB port and supports OTG connection, and a built-in battery module (which simultaneously meets features C and D).

[0038] Each input terminal corresponds to a unique row and column combination: top left input terminal (910) C1, R1; top input terminal (920) C2, R1; top right input terminal (930) C3, R1; left input terminal (940) C1, R2; center input terminal (950) C2, R2; right input terminal (960) C3, R2; bottom left input terminal (970) C1, R3; bottom input terminal (980) C2, R3; bottom right input terminal (990) C3, R3; leftmost input terminal (61) C4, R1; rightmost input terminal (62) C4, R2 (using the method of claim 6).

[0039] A circular position mark (9) is set on the surface (8) of the film (100) facing away from the base plate, and the corresponding character symbols are marked: the upper left input terminal (910) is marked with 1, 0, "symbol"; the upper right input terminal (920) is marked with a, b, c, 2; the upper right input terminal (930) is marked with d, e, f, 3; the left input terminal (940) is marked with g, h, i, 4; the middle input terminal (950) is marked with j, k, l, 5; the right input terminal (960) is marked with m, n, o, 6; the lower left input terminal (970) is marked with p, q, r, s, 7; the lower right input terminal (980) is marked with t, u, v, 8; the lower right input terminal (990) is marked with w, x, y, z, 9; the leftmost input terminal (61) is marked with a left arrow; and the rightmost input terminal (62) is marked with a right arrow.

[0040] like Figure 3 As shown, the leftmost input terminal (61) and the rightmost input terminal (62) are connected to the pluggable CD adapter female connector (extension interface 6130, 6140) respectively. The left foot pedal input terminal (6100) and the right foot pedal input terminal (6200) are circular foot pads with a diameter of 20cm. They are equipped with membrane switches inside and are wrapped with wear-resistant rubber on the outside. The pressing trigger force is 7N. They are connected to the CD adapter male connector (extension interface 6111, 6211) through a 1.5-meter long double-core flexible copper wire signal line. The trigger surfaces of the foot pedal input terminals are marked with the words "left" and "right" respectively.

[0041] When in use, the folder can be unfolded and placed on the desktop or fixed to the wall. Users can trigger each input terminal by punching or slapping, or by stepping on the input terminal to input the same command. The folder is less than 2cm thick after being folded, so it can be put directly into a backpack for carrying. The keyboard main control module (11) can be connected to a computer via Bluetooth or to a mobile phone via a USB+OTG adapter to transmit input commands.

[0042] Example 2 like Figure 2 As shown, this embodiment is the folder-integrated fitness electronic input keyboard of the second method described in claim 1. The crease area (85) in the figure is composed of two creases in the same direction. The fold width is less than 5 cm. The left input end (940), the middle input end (950), and the right input end (960) are all divided into upper and lower halves by the fold line. Each half is located on both sides of the fold line.

[0043] The conductive circuit is formed by bonding copper foil conductive tape (an equivalent alternative to claim 10), with a width of 8mm. The connecting circuit across the folded line is made of flexible copper foil, with a 1.5cm redundancy length reserved at the bend. The structural design of feature B is adopted, and the surface of the connecting circuit is coated with UV insulating ink. There are 4 insulating protrusions (82), with a height of 0.2mm, a diameter of 2mm, and a spacing of 0.5cm. The signal extension line (6) is 10cm long, and the signal line at the foot pedal input end is 2 meters long.

[0044] The leftmost input terminal (61) and the rightmost input terminal (62) adopt the second method of claim 6, that is, the two are electrically connected to the same unique row and column combination of the keyboard main control module signal receiving terminal through the connection line, and the combination is not repeated with the row and column combination of the nine input terminals.

[0045] The remaining structure, connection method, character labeling, and row and column combination are the same as in Example 1. It is suitable for folders that open vertically and whose width is greater than their height, and also achieves the functions of uniform distribution of input end, large contact area triggering and portable storage.
