Description

Technical Field

[0001] The invention relates to the technical field of keyboard key balance, in particular to a keyboard capable of improving balance. Background Art

[0002] A keyboard is a device for inputting instructions and data to operate computer equipment. It also refers to a set of function keys that are arranged by the system to operate a machine or equipment. The keyboard is the most commonly used and most important input device. English letters, Chinese characters, numbers, punctuation marks, etc. can be input into the computer through the keyboard, so as to issue commands to the computer and input data. There are also some keyboards with various shortcut keys. As time goes by, independent products with various shortcut functions are gradually sold separately on the market, and come with dedicated drivers and setting software, which can also realize personalized operations on compatible machines.

[0003] Keyboards are divided into mechanical keyboards according to their working principles. They use a metal contact switch similar to the one used in the keyboard. The working principle is to make the contact point conduct or disconnect. They have the characteristics of simple process, high noise, easy maintenance, strong sense of rhythm when typing, and no change in the feel after long-term use. Plastic membrane keyboards are divided into four layers inside the keyboard, achieving no mechanical wear. It is characterized by low price, low noise and low cost, but the feel will change due to material problems after long-term use. It has occupied most of the market share; the structure of the conductive rubber keyboard contact is connected by conductive rubber. There is a layer of conductive rubber with protrusions and charge inside the keyboard. Each key corresponds to a protrusion, and the contact below is connected when it is pressed. This type of keyboard is a transitional product from mechanical keyboards to membrane keyboards in the market; the contactless electrostatic capacitor keyboard uses a principle similar to that of a capacitive switch. When the key is pressed, the distance between the electrodes changes to cause the capacitance to change, thereby driving the encoder. It is characterized by no wear and good sealing.

[0004] In the prior art, a keyboard with an embedded balance bar structure disclosed in publication number "CN113506699A" includes a bracket plate, a key, an "X" structure group and a balance bar; the key and the "X" structure group are connected above the bracket plate, the balance bar includes an embedded portion and a first connecting portion and a second connecting portion respectively connected to two ends of the embedded portion, the embedded portion is embedded in the bracket plate and is located on one side or below the "X" structure group, the "X" structure group includes at least one "X" structure, the "X" structure is connected to the bracket plate, and the first connecting portion and the second connecting portion are respectively connected to two ends of the key; thereby, an embedded balance bar structure is realized, the overall structural strength of the key is improved, the action stability is improved, the balance of the key force action is guaranteed, thereby effectively preventing the key from being easily skewed, stuck, etc. during action, and the key has a better operating feel during action, and the automation of the balance bar assembly and the whole set of keys can be realized.

[0005] However, the existing technology still has major deficiencies, such as: In the above device and prior art: 1. Setting redundant structures in keyboard keys will greatly increase the difficulty of pressing the keys on the keyboard, causing the typist's fingers to be overly tired when typing, resulting in poor text input efficiency for the typist; 2. When enterprise typists input text, they need to press the first letter of the corresponding Chinese character, and press the space bar after the order of the Chinese characters is displayed. The existing technology adopts a single-axis pressing display for the space bar, but the space bar is large in size. In order to keep the space bar balanced after being pressed, a balance bar is set at the bottom of the space bar to achieve stability of the space bar. However, typists type at a fast speed and need to constantly tap the space bar while typing. High-frequency tapping of the space bar will cause fatigue and deformation of the balance bar inside the space bar, resulting in abnormal noise after the space bar is tapped. At the same time, the vertical balance state of the space bar after being pressed cannot be guaranteed, resulting in poor keyboard text input effect and affecting the service life of the keyboard.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] See also Figure 1-9 , the present invention provides a technical solution.

[0022] Embodiment 1: A keyboard capable of improving balance, comprising a keyboard bottom shell 1, a keyboard shaft positioning steel plate 2 and a keyboard key shaft 3, wherein the keyboard shaft positioning steel plate 2 is installed at the top area of ​​the keyboard bottom shell 1, and the keyboard key shafts 3 are arranged in a plurality of groups at intervals, and the plurality of groups of keyboard key shafts 3 are installed on the surface of the keyboard shaft positioning steel plate 2; A cross slot 331 is provided on the top of the fixing block 33 , and the cross clamping block 34 is inserted into the top of the cross slot 331 . The fixing block 33 is installed on the top of the pressing shaft rod 32 through the cross slot 331 .

[0023] In this embodiment, the present invention considers setting a structure on the keycaps on the keyboard surface. Although it will improve the quality of the keycaps, by setting the spring pressure inside the shaft body, the appropriate pressing force of the keycap area can be calibrated so that the pressure in the keycap area reaches a suitable pressing state.

[0024] A single-axis key balance installation unit is independently installed on the top of a single-group keyboard key shaft body 3, and is used to install a single-axis key cap, while maintaining the balance of the single-group keyboard key shaft body 3 when in use; The single-axis key balancing installation unit includes a small keycap 6, and a cross block 34 is installed in the inner top area of ​​the small keycap 6. The keyboard key shaft 3 includes a shaft bottom shell 35, and the shaft bottom shell 35 is installed on the surface of the keyboard shaft positioning steel plate 2. The upper surface of the shaft bottom shell 35 is installed with a shaft top shell 31, and a pressing shaft rod 32 is arranged in the shaft top shell 31. A fixing block 33 is installed on the top of the pressing shaft rod 32, and a cross block 34 is installed on the top of the fixing block 33. An arc guide groove 36 is arranged on the outer side of the shaft top shell 31. A balancing guide arc block 7 is obliquely installed on the inner wall of the small keycap 6. The surface of the balancing guide arc block 7 is smoothly set, and the smooth surface of the balancing guide arc block 7 is in active contact with the arc guide groove 36.

[0025] The arc-shaped guide grooves 36 are arranged in four groups at intervals, four groups of balance guide arc blocks 7 are installed in the small keycap 6 , and four groups of balance guide arc blocks 7 are also installed between the oblique mounting plate 8 and the small keycap 6 .

[0026] A through slot 71 is provided on the surface of the balance guide arc block 7 , a fixing frame 72 is installed in the through slot 71 , a rotating shaft 74 is installed on the fixing frame 72 , a sliding guide wheel 73 is provided on the surface of the rotating shaft 74 , and the sliding guide wheel 73 is in active contact with the arc guide slot 36 .

[0027] In this embodiment, a small keycap 6 is installed on the surface of the single-axis keyboard key shaft body 3. The signal of this part of the keyboard key shaft body 3 is independently output to the outside. The user can output the corresponding letter, number or symbol by pressing. When the small keycap 6 is pressed, the cross block 34 in the bottom area of ​​the small keycap 6 can ensure that the pressure on the top of the small keycap 6 is balanced and transmitted to the fixing block 33 and the pressing shaft rod 32 area, so that the pressing shaft rod 32 is pressed in a balanced manner, ensuring that the pressing shaft rod 32 is pressed evenly, reducing the risk of breaking the pressing shaft rod 32, and improving the service life of the keyboard key shaft body 3 on the keyboard surface; When the typist presses the small keycap 6 to output a signal, letters, numbers or symbols are output on the surface of the small keycap 6, which makes the pressing frequency of the small keycap 6 higher than that of the dual-axis keycap 4 and the tri-axis keycap 5. At the same time, a balancing guide arc block 7 is installed inside the small keycap 6. The arc-shaped smooth surface of the balancing guide arc block 7 can contact the surface of the arc-shaped guide groove 36 when the small keycap 6 is subjected to lateral tilt pressure, thereby maintaining the vertical pressing state of the small keycap 6, further avoiding the shaking of the small keycap 6, and further ensuring that the pressing shaft 32 is under balanced pressure.

[0028] A multi-axis key balance installation unit is installed on the top of multiple sets of keyboard key shaft bodies 3, and is used to install multi-axis key caps while maintaining the balance of multiple sets of keyboard key shaft bodies 3 when in use; The multi-axis key balancing installation unit includes a double-axis keycap 4 and a three-axis keycap 5. The double-axis keycap 4 and the three-axis keycap 5 are both installed with oblique installation plates 8 at intervals. Two groups of oblique installation plates 8 are arranged inside the double-axis keycap 4, and four groups of oblique installation plates 8 are arranged inside the three-axis keycap 5. Multiple groups of oblique installation plates 8 are respectively installed obliquely inside the double-axis keycap 4 and the three-axis keycap 5, and a balancing guide arc block 7 is also installed on the surface of the oblique installation plate 8.

[0029] In this embodiment, the biaxial keycap 4 and the triaxial keycap 5 are installed in the function key area. Since the pressing frequency of the function key area is relatively low, the surface wear of the biaxial keycap 4 and the triaxial keycap 5 is relatively small. However, the keyboard specifications are arranged so that the biaxial keycap 4 and the triaxial keycap 5 occupy a larger area of ​​the keyboard surface. When the function keys are pressed for a long time, abnormal noise may occur in the function key area. Therefore, the biaxial keycap 4 and the triaxial keycap 5 are embedded with an oblique mounting plate 8. The oblique mounting plate 8 can cooperate with the side walls of the biaxial keycap 4 and the triaxial keycap 5 to arrange the balance guide arc blocks 7 in multiple groups at intervals, thereby ensuring the pressure balance of the biaxial keycap 4 and the triaxial keycap 5 in the function key area and avoiding the occurrence of abnormal noise problems in the axis bodies of the biaxial keycap 4 and the triaxial keycap 5.

[0030] A space bar balancing installation unit is installed on the top of multiple sets of keyboard key shaft bodies 3. The space bar balancing installation unit can perform balanced installation on large-sized space bar keycaps to ensure that the space bar keycaps maintain a balanced pressing state when used at high frequencies; The space bar balance installation unit includes a space bar cap 9, eight groups of oblique mounting plates 8 are arranged inside the space bar cap 9, five groups of cross blocks 34 are installed between the eight groups of oblique mounting plates 8 and the inner wall of the space bar cap 9, and the space bar cap 9 is installed on the top of the five groups of keyboard key shafts 3 through the cross blocks 34.

[0031] In this embodiment, the size of the space bar is larger than the various function keys and single-axis keys on the keyboard surface. By setting up multiple groups of keyboard key shafts 3, it is possible to support and install the large-volume space bar cap 9. At the same time, more groups of inclined mounting plates 8 and balancing guide arc blocks 7 are provided at the bottom of the space bar cap 9. At the same time, a sliding guide wheel 73 is installed in the balancing guide arc block 7. When the sliding guide wheel 73 is subjected to abnormal lateral pressure, it fits on the surface of the arc guide groove 36, which can further reduce the risk of breakage of the pressing shaft 32.

[0032] Embodiment 2: Based on the first embodiment, in this embodiment, it is considered that since the function keys and the space bar are both provided with multiple groups of keyboard key shaft bodies 3, if the keyboard key shaft bodies 3 of independent groups are provided, when the keyboard key shaft bodies 3 of independent groups are damaged, the function keys and the space bar signals will be output normally. Therefore, in this embodiment, multiple groups of keyboard key shaft bodies 3 are provided in parallel; The space bar area at the top of the keyboard axis positioning steel plate 2 is composed of five groups of keyboard key axis bodies 3, and the signals of the five groups of keyboard key axis bodies 3 are arranged in parallel.

[0033] The TAB key, CAPS key and comma key on the top of the keyboard axis positioning steel plate 2 are composed of two groups of keyboard key axis bodies 3, and the signals of the two groups of keyboard key axis bodies 3 are arranged in parallel.

[0034] The SHIFT key and the ENTER key on the top of the keyboard axis positioning steel plate 2 are composed of three groups of keyboard key axis bodies 3, and the signals of the three groups of keyboard key axis bodies 3 are set in parallel.

[0035] In the present embodiment, multiple groups of keyboard key shafts 3 in the areas of the space bar cap 9, the biaxial key cap 4 and the triaxial key cap 5 are installed in parallel on the PCB board of the keyboard. Due to the parallel setting state, the space bar cap 9, the biaxial key cap 4 and the triaxial key cap 5 can trigger signals by pressing from various areas on the top. Since the keyboard key shafts 3 have a service life, but in the parallel setting state, even if the keyboard key shafts 3 are replaced, other groups of keyboard key shafts 3 can be triggered by pressing to output signals. At the same time, the keyboard key shafts 3 that cannot trigger signals still have their vertical mechanical pressure function, and can still maintain the balanced state of the space bar cap 9, the biaxial key cap 4 and the triaxial key cap 5 being pressed.

[0036] Embodiment three: In this embodiment, a button 91, a bracket plate 92, an X structure 93 and a balance bar 95 are mentioned, wherein a mounting position 94 for loading the balance bar 95 is provided on the surface of the bracket plate 92, and the balance bar 95 is loaded in the mounting position 94, and the X structure 93 includes a first bracket and a second bracket, one end of the first bracket is hinged to one end of the second bracket, and the other end of the first bracket and the other end of the second bracket are both connected to the button 91, one end of the first bracket is provided with a sliding fulcrum, and one end of the second bracket is provided with a fixed fulcrum, and the bracket plate 92 is provided with a first supporting part and a second supporting part; the sliding fulcrum is rotatably connected to the first supporting part and can slide relative to the first supporting part; the fixed fulcrum is only rotatably connected to the second supporting part; The X structure mentioned in the above solution can be used as another implementation of the present invention. Both implementations can improve the balance of the keycaps on the keyboard surface during use and extend the service life of the keycaps.

[0037] Working principle: During the use of the device, a small keycap 6 is installed on the surface of the single-axis keyboard key shaft 3. The signal of this part of the keyboard key shaft 3 is independently output to the outside. The user can output the corresponding letter, number or symbol by pressing. When the small keycap 6 is pressed, the cross block 34 in the bottom area of ​​the small keycap 6 can ensure that the pressure on the top of the small keycap 6 is balanced and transmitted to the fixing block 33 and the pressing shaft 32 area, so that the pressing shaft 32 is pressed in a balanced manner, ensuring that the pressing shaft 32 is pressed evenly, reducing the risk of breaking the pressing shaft 32, and increasing the service life of the keyboard key shaft 3 on the keyboard surface; When the typist presses the small keycap 6 to output a signal, letters, numbers or symbols are output on the surface of the small keycap 6, which makes the pressing frequency of the small keycap 6 higher than that of the double-axis keycap 4 and the three-axis keycap 5. At the same time, a balance guide arc block 7 is installed inside the small keycap 6. The arc-shaped smooth surface of the balance guide arc block 7 can contact the surface of the arc-shaped guide groove 36 when the small keycap 6 is subjected to lateral tilt pressure, thereby maintaining the vertical pressing state of the small keycap 6, further avoiding the shaking of the small keycap 6, and further ensuring that the pressing shaft 32 is pressed evenly. The biaxial keycap 4 and the triaxial keycap 5 are installed in the function key area. Since the pressing frequency of the function key area is low, the surface wear of the biaxial keycap 4 and the triaxial keycap 5 is small. However, the keyboard specifications make the biaxial keycap 4 and the triaxial keycap 5 occupy a large area of ​​the keyboard surface. When the function key is pressed for a long time, the function key area may also have abnormal noise problems. Therefore, the biaxial keycap 4 and the triaxial keycap 5 are embedded with an oblique mounting plate 8. The oblique mounting plate 8 can cooperate with the side walls of the biaxial keycap 4 and the triaxial keycap 5 to arrange and install the balance guide arc blocks 7 in multiple groups at intervals, thereby ensuring the pressure balance of the biaxial keycap 4 and the triaxial keycap 5 in the function key area, and avoiding the occurrence of abnormal noise problems of the biaxial keycap 4 and the triaxial keycap 5 shaft bodies. The space bar is larger in size than the various function keys and single-axis keys on the keyboard surface. Multiple sets of keyboard key shafts 3 are provided to support and install the large-volume space bar cap 9. At the same time, more sets of oblique mounting plates 8 and balance guide arc blocks 7 are provided at the bottom of the space bar cap 9. At the same time, a sliding guide wheel 73 is installed in the balance guide arc block 7. When the sliding guide wheel 73 is subjected to abnormal lateral pressure, it fits on the surface of the arc guide groove 36, which can further reduce the risk of the pressing shaft rod 32 breaking. Multiple groups of keyboard key shafts 3 in the areas of the space bar cap 9, double-axis key cap 4 and three-axis key cap 5 are installed in parallel on the PCB board of the keyboard. Due to the parallel setting, the space bar cap 9, double-axis key cap 4 and three-axis key cap 5 can trigger signals by pressing from various areas on the top. Since the keyboard key shafts 3 have a service life, but in the parallel setting, even if the keyboard key shafts 3 are replaced, other groups of keyboard key shafts 3 can be triggered by pressing to output signals. At the same time, the keyboard key shafts 3 that cannot trigger signals still have their vertical mechanical pressure function, and can still maintain the balanced state of the space bar cap 9, double-axis key cap 4 and three-axis key cap 5 when they are pressed.
