[0025] Footpads: Bottom pads that provide stability and anti-slip properties.

[0026] Support structure: formed on the bottom upper edge of the keyboard, used to support the upper part of the keyboard to form a certain angle for typing operations.

[0027] Although different types of keyboards vary in design and functionality, the basic structural components are similar.

[0028] Early keyboards usually could only use support structures to provide a certain keyboard support inclination angle, such as 5 degrees; when a keyboard support inclination angle is needed, the keyboard support structure is manually opened to obtain the required keyboard inclination angle. With the development of technology, support structures that can provide multiple keyboard support inclination angles have emerged. These support structures achieve multiple keyboard support inclination angles by manually adjusting the support structure to stay in different fixed positions. This solution can only provide a limited number of keyboard support inclination angles, usually full-angle fixed positions, such as 1 degree, 2 degrees, 3 degrees, 4 degrees or 5 degrees, and the keyboard support inclination angle range that can be provided is also limited, usually 0 degrees to 10 degrees.

[0029] In the actual use of the keyboard, due to the influence of factors such as different palm sizes and usage habits of users, the keyboard support angles suitable for users are also different. In this use environment, the existing keyboard support structure has the following defects that need to be improved:

[0030] 1. The existing keyboard support structure can only achieve support at a specific angle through mechanical clamping, and the number of support angles that can be provided is limited, and it cannot provide support positions for any keyboard support angle. Not all users are adapted to keyboard support angles of integer angles. The existing keyboard support structure has a small scope of application and the defect of too few support angles that can be provided needs to be improved.

[0031] 2. The existing keyboard support structure needs to be manually adjusted by mechanical clamps. When manually adjusting, the keyboard operation must be stopped and the keyboard support structure must be touched by hand. In certain specific situations (for example, in e-sports competitions), it is impossible to stop the operation and manually adjust the keyboard support angle. The existing keyboard support structure has the defects of limited practicality and inconvenient operation, which needs to be improved. Summary of the invention

[0071] Preferably, the keyboard support adjustment structure is further improved so that when it supports the keyboard, the angle between the keyboard and the horizontal direction is greater than or equal to 0 degrees and less than 90 degrees.

[0072] The present invention provides a keyboard having any one of the keyboard support adjustment structures described above.

[0073] The present invention uses one of the three embodiments of the present invention (the protection scheme claimed in claim 7) to illustrate the working principle as follows;

[0074] When the user needs to raise or lower the keyboard, the motor can be triggered to output positive torque through commands (for example, by pressing the plus key on the keyboard). The transmission assembly amplifies the torque and transmits it to the first transmission member (the horizontal transmission member, i.e., the rack). The sliding block at the end of the first transmission member overcomes the friction between the bottom surface of the sliding block and the bottom wall of the lower shell of the keyboard. The sliding block slides and pushes the second transmission member (connecting rod), causing the second transmission member to move from an inclined state to a vertical state, thereby lifting or lowering the upper part of the keyboard, changing the angle between the keyboard and the horizontal direction, and stopping the operation after the desired keyboard support inclination angle is reached.

[0075] When the user's hands are not pressing on the keyboard, the gravity of the keyboard increases the friction between the bottom surface of the sliding block and the bottom wall of the keyboard lower shell, thereby fixing the position of the sliding block, so that the keyboard support inclination angle is also fixed.

[0076] When the user presses his hand on the keyboard to operate the keyboard, the friction between the bottom surface of the sliding block and the bottom wall of the keyboard lower shell is further increased due to the gravity of the keyboard, the gravity of the user's hand and the pressure of the user's hand on the keyboard, thereby fixing the position of the sliding block, and thus fixing the keyboard support inclination angle. Correspondingly, in theory, after the motor reaches the specified position and the output end is fixed, it will also damp the movement of the sliding block.

[0077] When the user needs to lower the keyboard, the motor can be triggered to output reverse torque through an instruction (for example, pressing the minus key on the keyboard). The first transmission member amplifies the torque and transmits it to the horizontal transmission member. The first transmission member pushes the sliding block at its end to overcome the friction between the bottom surface of the sliding block and the bottom wall of the lower shell of the keyboard. The sliding block slides and pulls the second transmission member. Under the combined action of the keyboard's own gravity and the pulling force of the sliding block, the second transmission member tends from the current state to a more inclined state, thereby lowering the upper part of the keyboard, changing the angle between the keyboard and the horizontal direction, and stopping the operation after the desired keyboard support inclination angle is reached.

[0078] The technical effects of the present invention are as follows:

[0079] 1. The present invention realizes stepless adjustment of the keyboard support inclination angle by driving the transmission component through a power source, and utilizes the gravity of the keyboard, the friction between the transmission component and the bottom wall of the keyboard lower shell, or the output force of the power source to fix the keyboard at any desired keyboard support inclination angle, thereby expanding the applicability of the keyboard.

[0080] 2. Based on the structure described in point 1 above, the present invention can provide a larger keyboard support inclination angle range than the prior art, and design a transmission component of suitable size. Theoretically, the present invention can provide a keyboard support inclination angle range greater than or equal to 0 degrees and less than 90 degrees, thereby expanding the applicability of the keyboard.

[0081] 3. The present invention can realize stepless adjustment of the keyboard support angle. The keyboard support angle can be any angle less than 90 degrees. The keyboard support angle is no longer limited to a few angles or integer angles.

[0082] 4. The present invention does not require manual touch to operate the keyboard support structure, and the keyboard support inclination angle can be adjusted through instructions, which is easy to operate, and the keyboard support inclination angle can be set to be fixed through instructions to achieve one-key adjustment.

[0097] First embodiment;

[0098] The present invention provides a keyboard support adjustment structure, comprising:

[0099] A power source is fixed in the keyboard housing and can drive the upper part of the keyboard upper housing 5 to rise and fall steplessly;

[0100] Or, it can drive the upper part of the keyboard upper shell 5 to rise and fall steplessly through the transmission component;

[0101] The power source can control the upper part of the keyboard upper shell 5 to stop at any specified height according to instructions.

[0102] The command is triggered by a keyboard key;

[0103] Or, the instruction is triggered by a combination of a keyboard key and the pressing time of the key;

[0104] Or; the instruction is triggered by a combination of keyboard key combinations and the pressing time of the key combinations;

[0105] Or, the instruction is triggered by an external control instruction forwarded by the keyboard wireless communication module;

[0106] Alternatively, the instruction is triggered by a keyboard touch control function component.

[0107] The following are possible implementation methods for instructions:

[0108] The command is triggered by a keyboard key. For example, pressing the plus key will cause the keyboard to rise or fall. The rising or falling angle is determined by the accuracy of the stepper motor. By default, the plus key is pressed once, the stepper motor runs one minimum unit, and the keyboard rises or falls the minimum unit. If the key is pressed continuously, it will continue to rise or fall.

[0109] Or, the command keyboard key combination triggers; for example, by pressing the ctrl key and the plus key at the same time, the stepper motor runs a minimum unit, the keyboard rises and falls the minimum unit, and the keyboard rises and falls continuously if the key is pressed continuously. The keyboard tilt angle can also be pre-set to bind the plus key, so that the keyboard tilt angle can be adjusted to the required one-click.

[0110] Or, the command is triggered by a combination of a keyboard key and the time the key is pressed; for example, if the plus key is pressed for 0.1 seconds, the stepper motor runs one minimum unit and the keyboard rises or falls one minimum unit; if the plus key is pressed for 0.2 seconds, the stepper motor runs two minimum units and the keyboard rises or falls two minimum units.

[0111] Or; the command keyboard key combination and the combination of pressing time of the key combination are triggered; for example, the ctrl key and the plus key are pressed simultaneously and continuously for 0.1 seconds, and the stepper motor runs one minimum unit; the ctrl key and the plus key are pressed simultaneously and continuously for 0.2 seconds, and the stepper motor runs two minimum units, and the keyboard rises and falls two minimum units.

[0112] Or, the command is triggered by an external control command forwarded by the keyboard wireless communication module; for example, a control command is sent via wireless Bluetooth using a mobile phone APP, and a corresponding keyboard tilt angle raising and lowering button is provided through software; or, the keyboard tilt angle is bound by software to achieve one-click adjustment of the keyboard tilt angle.

[0113] Or, the instruction is triggered by the keyboard touch control function component. For example, executing a specified first sliding action on the keyboard touch control function component causes the keyboard to rise, and executing a specified second sliding action causes the keyboard to fall.

[0114] Based on the principle of the first embodiment, the present invention provides three preferred implementation modes, namely, the second embodiment to the fourth embodiment.

[0115] Second embodiment;

[0116] refer to Figure 1 As shown, the second embodiment of the present invention is based on the principle of the above-mentioned first embodiment, and the same parts are not repeated here. In this embodiment, the upper part of the keyboard upper shell 5 is stopped at any specified height through a power source.

[0117] Power sources include:

[0118] The first sub-power source 1 is used to drive the second sub-power source 2 to support the lifting of the keyboard.

[0119] Preferably, the first sub-power source 1 is a stepper motor, which is used to control the gas pressure in the pneumatic telescopic rod;

[0120] The second sub-power source 2 is a pneumatic telescopic rod, the upper end of which supports the upper inner wall of the keyboard upper shell 5 or the upper bottom wall of the PCB, and is used to support the lifting of the upper part of the keyboard.

[0121] Third embodiment;

[0122] refer to Figure 2 As shown, the third embodiment of the present invention is based on the principle of the above-mentioned first embodiment, and the same parts are not repeated here. In this embodiment, the upper part of the keyboard upper shell 5 stops at any specified height through the combination of the power source and the transmission assembly.

[0123] In this embodiment, the power source is a motor, preferably a stepper motor;

[0124] The transmission components include:

[0125] A first transmission member 3, which is driven by a power source to reciprocate in a first direction, the first direction is not a vertical direction, and preferably the first direction is a horizontal direction; preferably, the first transmission member 3 is a rack 3.1 with a sliding block 3.2 at the end thereof driven by the motor output shaft;

[0126] The second transmission member 4 has a lower end shaft connected to the first transmission member 3, and an upper end shaft connected to the upper inner wall of the keyboard upper shell 5 or the upper bottom wall of the PCB, and is used to support the lifting of the upper part of the keyboard; preferably, the second transmission member 4 is a connecting rod, the lower end shaft of the connecting rod is connected to the sliding block 3.2, and the upper end shaft of the connecting rod is connected to the upper inner wall of the keyboard upper shell 5 or the upper bottom wall of the PCB, and is used to support the lifting of the upper part of the keyboard;

[0127] The power source controls the moving distance of the first transmission member 3 according to the instruction, and further controls the second transmission member 4 to raise or lower the height of the upper part of the keyboard upper shell 5 .

[0128] The third embodiment described above is further improved, and the friction coefficient between the bottom surface of the sliding block 3.2 and the bottom wall of the keyboard lower shell is greater than or equal to 0.3 and less than 0.5. It should be further explained that the above friction coefficient cannot be understood as a conventional choice. Because the bottom surface of the sliding block and the bottom wall of the keyboard lower shell must be able to form sliding while providing sufficient friction to fix the keyboard support inclination angle, the bottom surface of the sliding block and the bottom wall of the keyboard lower shell cannot be too smooth or too rough. The above friction coefficient is designed in consideration of the gravity of the keyboard, the gravity of the user's hand, the pressure used to press the hand on the keyboard, and the transmission structure of the support structure provided by the present invention, to ensure that the present invention can fix any keyboard inclination angle while achieving the adjustment of the keyboard inclination angle through motor drive.
