[0002] Computer keyboards are one of the most commonly used peripherals for desktop and laptop computers, used for character input or computer control.

[0003] Computer keyboards are usually placed on a desktop or table in front of the user, who taps or presses the keys on the keyboard with their fingers.

[0004] Because users have different heights or habits, computer keyboards are usually equipped with flip-up feet at the bottom. When the feet are flipped open relative to the keyboard body, they can support the bottom of the keyboard, allowing the keyboard to tilt at a specific angle, thus making it easier for users to use the keyboard.

[0005] Most common keyboards on the market only have two states for their feet, allowing for limited adjustment of angle and posture. Existing technology, such as the Chinese utility model patent with publication number "CN213236670U" entitled "An Adjustable Tilt Keyboard," discloses the following solution: "An adjustable tilt keyboard includes a rectangular keyboard housing. A clearance cavity is provided on the long side of the housing away from the user. A roller is adapted to connect in the clearance cavity. A clearance groove is provided on the bottom surface of the housing near the clearance cavity, extending along the length of the housing. A controllable lifting and lowering movable block is provided in the clearance groove. A rotating shaft is provided in the middle of the roller, extending along the width of the housing. A transmission component is provided between the movable block and the rotating shaft to drive the lifting and lowering movement of the movable block."

[0006] In the above solution, the user rotates the scroll wheel, which is then driven by the transmission component to raise or lower the movable block, thereby making the keyboard tilt angle smaller or larger. It can be adjusted according to different people's preferences and has a wide range of applications.

[0007] Although the above solution can achieve multi-level adjustment of keyboard tilt, its structure is relatively complex and the adjustment structure occupies a lot of space inside the keyboard. Utility Model Content

[0043] The working principle of this utility model is as follows:

[0044] The adjustment mechanism of the keyboard body 1 in this design has four postures, corresponding to four tilt angles of the keyboard body 1, namely:

[0045] The keyboard is in its lowest position; that is, the footplate 3, secondary footplate 5, and tertiary footplate 6 are all closed and located in the bottom groove 2. In this position, the keyboard body 1 is laid flat, and the footplate 3, secondary footplate 5, and tertiary footplate 6 do not provide support for the keyboard body 1.

[0046] The keyboard is in a low posture; that is, the support plate 3 and the secondary support foot 5 are located in the bottom groove 2, and only the tertiary support foot 6 is flipped out relative to the bottom groove 2 and abuts against the limiting surface 21 to support the keyboard body 1; at this time, the tilt angle of the keyboard body 1 is greater than the lowest posture of the keyboard.

[0047] The keyboard is in a higher posture; that is, the support plate 3 and the third-level support 6 are closed and located in the bottom groove 2, and only the second-level support 5 is flipped out relative to the bottom groove 2 and abuts against the limiting surface 21 to form support for the keyboard body 1; at this time, the tilt angle of the keyboard body 1 is greater than that of the keyboard in a lower posture.

[0048] The keyboard is in its highest position; that is, the secondary support foot 5 and the tertiary support foot 6 are both closed and located in the bottom groove 2, and only the support foot plate 3 is flipped out relative to the bottom groove 2 and abuts against the limiting surface 21 to form support for the keyboard body 1; at this time, the tilt angle of the keyboard body 1 is greater than the keyboard's highest position, which is the maximum tilt angle.

[0049] When the footplate 3 flips out relative to the bottom groove 2 to support the keyboard body 1, the first adhesive strip 32 on the first flange 31 at the end of the footplate 3 contacts the desktop or table surface to prevent slipping.

[0050] When the secondary support foot 5 flips out relative to the bottom groove 2 to support the keyboard body 1, the second rubber strip 52 on the second flange 51 at the end of the secondary support foot 5 contacts the desktop or table surface to play an anti-slip role.

[0051] When the three-stage support foot 6 flips out relative to the bottom groove 2 to support the keyboard body 1, the third rubber strip 62 on the third flange 61 at the end of the three-stage support foot 6 contacts the desktop or table surface to play an anti-slip role.

[0052] The two support plates 3 at both ends of the bottom of the keyboard body 1 can be flipped out or closed simultaneously; the two secondary support feet 5 at both ends of the bottom of the keyboard body 1 can be flipped out or closed simultaneously; the two tertiary support feet 6 at both ends of the bottom of the keyboard body 1 can be flipped out or closed simultaneously to form a stable support for the keyboard body 1.
