Detailed Implementation

[0015] It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0016] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0017] Example 1: As Figures 1-9 As shown, a keyboard stand includes a wrist rest 100, which is connected to a pair of forward-extending brackets for placing the keyboard, namely a left bracket 200 and a right bracket 300. A silicone pad 500 is provided on top of the wrist rest 100, which can be placed directly on or attached to the wrist rest 100 for easy movement. An adjustment mechanism 400 for adjusting the tilt angle of the keyboard stand is provided below the right bracket. When a user operates the keyboard with their left hand (generally when playing games, only the left hand is needed to operate the keyboard and the right hand to operate the mouse), the adjustment mechanism can be used to raise the right side of the keyboard stand to a certain height, tilting the keyboard stand at a certain angle. This reduces the degree of rotation of the left forearm and improves comfort; it also increases the space between the radius and ulna, reducing stimulation of the carpal tunnel nerve and decreasing the probability of tenosynovitis, thus alleviating and preventing tenosynovitis (commonly known as keyboard hand). When both hands are needed to operate the keyboard, the keyboard stand returns to a horizontal position. The wrist rest is tilted at the same angle as the keyboard, ensuring that the wrist receives continuous and consistent support throughout the operation. This avoids the wrist being suspended or misaligned due to the wrist rest not changing position when the keyboard is tilted, significantly improving support and comfort.

[0018] In this embodiment, the adjustment mechanism 400 includes a support plate 410 hinged to the bottom of the right bracket and capable of swinging left and right, and an angle limiting mechanism. The support plate 410 can swing to one side (left) to be close to the bottom surface of the right bracket, and when it swings to the other side (right), it is limited to a set angle by the angle limiting mechanism. When the support plate swings to the left to be close to the bottom surface of the right bracket, the support plate will not lift the right side of the keyboard bracket, and the keyboard bracket is in a horizontal state for two-handed keyboard operation. When the support plate swings to the right, the support plate is limited to a specified angle by the angle limiting mechanism, the support plate lifts the right bracket, and the keyboard bracket is in an inclined state with the left side lower and the right side higher, for single-handed keyboard operation with the left hand.

[0019] In practice, the position of the support plate can be changed when it swings left and right. When it swings to the right, it can be close to the bottom of the right bracket, and when it swings to the left, it is restricted to a set angle.

[0020] In this embodiment, the left bracket 200, right bracket 300, and wrist support 100 are connected by two connecting screws. The left bracket 200 and right bracket 300 have threaded holes that mate with the connecting screws. The left side of the wrist support 100 has several sets of connecting holes 110 arranged at intervals along the left-right direction. The connecting screw connects to one set of connecting holes on the left bracket. By selecting different positions of the connecting holes, the left-right position of the left bracket can be adjusted. The right side of the wrist support 100 has a long slot 120 through which the connecting screw passes. By adjusting the position of the connecting screw in the long slot 120, the left-right position of the right bracket can be adjusted.

[0021] In this embodiment, the angle limiting mechanism includes a fixed plate 420 connected to the bottom of the right bracket, and a support plate hinged to the fixed plate by a pin. A slider 430 is located on the other side (right side) of the support plate and slides left and right with the fixed plate. Limiting blocks 460 are provided on the front and rear sides of the slider to abut against the support plate and limit the swing angle when the support plate swings to the other side (right side). By adjusting the left and right position of the slider, the support plate can be limited to different angles. When the slider slides to the left, the angle between the support plate and the right bracket increases, and the keyboard bracket tilt angle increases. When the slider slides to the right, the angle between the support plate and the right bracket decreases, and the keyboard bracket tilt angle decreases. The tilt angle can be adjusted to suit different users' habits.

[0022] In this embodiment, the fixing plate 420 has an elongated hole 421 in the middle, with its length direction parallel to the sliding direction of the slider. The upper side of the fixing plate has a channel 422 located above the elongated hole. A square nut 440 that can slide relative to the channel is provided in the channel. A screw 450 is inserted from bottom to top through the middle of the slider. After the screw passes through the elongated hole, it is connected to the square nut. For ease of operation, the screw 450 is a hand-tightening screw, which is convenient for the user to adjust at any time. When the screw 450 is loosened, the slider, screw and square nut can move together for adjustment. After adjustment, the screw 450 is tightened, and the square nut and slider cooperate to clamp the fixing plate, and the slider can no longer move.

[0023] In this embodiment, in order to ensure that the slider is stable after locking, the lower side of the fixing plate is provided with an upper toothed surface 423, and the upper side of the slider 430 is provided with a lower toothed surface 431.

[0024] In this embodiment, the slider 130 is groove-shaped and is upside down on the underside of the fixing plate. The fixing plate has sliding grooves 424 on both the front and rear sides. The slider 430 has protruding buckles 432 on both the front and rear sides that extend into the sliding grooves and can slide along the sliding grooves.

[0025] In this embodiment, to prevent the left hand from slipping when the keyboard bracket is tilted, a wrist support bracket 600 is provided at the left end of the wrist support bracket; the wrist support bracket 600 includes a base plate 610 and a support plate 620 located above the base plate. The support plate 620 is hinged to the base plate 610 on the left side so that the support plate can swing up and down, and the silicone pad 500 extends above the support plate.

[0026] In this embodiment, the base plate has a boss 611 in the middle, and a plurality of insertion holes 612 are arranged at intervals in the left and right direction on the boss. A stop shaft 630 is inserted through one of the insertion holes. The two ends of the stop shaft extend out of the insertion hole. The underside of the support plate has a rib 621 that abuts against the two ends of the stop shaft to limit the angle of the support plate. The stop shaft 630 is inserted through different insertion holes 612, so that the angle of the support plate 620 can be adjusted.

[0027] The wrist support bracket 600 and the wrist support 100 can be a separate structure, and the wrist support bracket 600 can be removed when not in use; they can also be detachably connected, such as by screws connecting the base plate and the wrist support 100, or by adhesive tape connecting the support plate and the wrist support 100 or connecting the base plate and the wrist support 100; or they can be an integrated structure, that is, the base plate and the wrist support 100 are set as a single structure.

[0028] Example 2: The difference between this example and Example 1 is that the adjustment mechanism is located on the left side.

[0029] A keyboard stand includes a wrist rest connected to a pair of forward-extending brackets for placing the keyboard, namely a left bracket and a right bracket. A silicone pad is provided above the wrist rest, and an adjustment mechanism 400 for adjusting the tilt angle of the keyboard stand is located below the left bracket. The specific structure of the adjustment mechanism 400 is the same as in Embodiment 1. When the user operates the keyboard with their right hand, the adjustment mechanism can be used to raise the left side of the keyboard stand to a certain height, tilting the keyboard stand at a certain angle, reducing the degree of rotation of the right forearm and improving comfort; when both hands are needed to operate the keyboard, the keyboard stand returns to a horizontal state.

[0030] In this embodiment, to prevent the right hand from sliding down when the keyboard bracket is tilted, a wrist support bracket is provided at the right end of the wrist rest; the specific structure of the wrist support bracket is the same as in Embodiment 1, and the silicone pad 500 extends above the support plate.

[0031] Example 3: The difference between this example and Example 1 is that adjustment mechanisms are provided on both the left and right sides.

A silicone pad is provided above the wrist rest, and adjustment mechanisms 400 for adjusting the tilt angle of the keyboard stand are provided below both the left and right brackets. The specific structure of the adjustment mechanism 400 is the same as in Embodiment 1. Users can adjust the keyboard stand to tilt to the left or right as needed. When the keyboard stand needs to be horizontal, the support plates of both adjustment mechanisms 400 swing to be close to the bottom surface of the wrist rest. When the keyboard stand needs to tilt to the left, the support plates of the left adjustment mechanism 400 swing to be close to the bottom surface of the wrist rest, and the support plate of the right adjustment mechanism 400 swings to a set angle, at which point the silicone pad moves to the left so that it is above the bracket. When the keyboard stand needs to tilt to the right, the support plates of the right adjustment mechanism 400 swing to be close to the bottom surface of the wrist rest, and the support plate of the left adjustment mechanism 400 swings to a set angle, at which point the silicone pad moves to the right so that it covers the top of the bracket.

[0033] In this embodiment, to prevent the hand from slipping down the lower side when the keyboard stand is tilted, a wrist support bracket is provided at one end of the wrist rest; the specific structure of the wrist support bracket is the same as in embodiment one; the wrist support bracket and the wrist rest adopt a split structure, and the wrist support bracket can be moved to the left or right end at any time.
