[0032] As shown in Figures 1 to 6, this embodiment of the invention provides a keyboard, including a keyboard body 2 and a keyboard protective cover 1. The keyboard protective cover 1 includes a cover plate 11, a connecting component, and an auxiliary support 14. The connecting component includes a first connector 12 and a second connector 13. The first connector 12 and the second connector 13 are rotatably connected, and the second connector 13 is rotatably connected to the back of the cover plate 11. The auxiliary support 14 is located at the rotatable connection between the second connector 13 and the cover plate 11 and is rotatable. A connecting groove is provided on the rear side of the keyboard body 2, and the first connector 12 is magnetically connected to the connecting groove. The magnetic connection allows for easy disassembly. Specifically, a magnetic piece is provided on the groove wall, and a magnet is provided on the portion of the first connector 12 embedded in the connecting groove.

[0033] As a component that directly covers the keyboard, the cover plate 11 is shaped and sized to match the keyboard body 2, providing protection against dust, water, and scratches. The cover plate 11 is designed to completely cover the key area on the front of the keyboard.

[0034] The first connector 12 and the second connector 13 are key components for enabling the cover plate 11 to open and close at multiple angles. The first connector 12 and the second connector 13 are rotatably connected by a rotating shaft, which can be a common pin. A shaft hole is provided on the first connector 12, and a corresponding shaft hole is also provided on the second connector 13. The pin passes through the two shaft holes, allowing the first connector 12 and the second connector 13 to rotate relative to each other.

[0035] In one embodiment, the second connector 13 is rotatably connected to the cover plate 11 via a damping shaft 15. A fixing block 115 with a fixing hole is provided on the back of the cover plate 11. The damping shaft 15 includes a screw, a nut, and a damping washer. The screw passes through the fixing hole and is connected to the nut. The damping washer is located between the screw and the nut. By adjusting the tightness of the nut and the screw, the damping magnitude can be adjusted, ensuring that the cover plate 11 has appropriate resistance during rotation, allowing for easy angle adjustment and stable angle maintenance after adjustment.

[0036] As shown in Figure 5, the second connector 13 includes a horizontal plate portion 131 and a vertical plate portion 132 connected to the horizontal plate portion 131. The connection method is either a fixed connection or integral molding. The second connector 13 is generally L-shaped. The side of the vertical plate portion 132 away from the horizontal plate portion 131 is hinged to the cover plate 11. The side of the horizontal plate portion 131 away from the vertical plate portion 132 is connected to the first connector 12 by a pin.

[0037] The auxiliary support 14 includes bent rod-shaped members, comprising a horizontal base rod 141, a first vertical support rod 142, a second vertical support rod 143, a first horizontal top rod 144, and a second horizontal top rod 145. The first vertical support rod 142 and the second vertical support rod 143 are located at both ends of the horizontal base rod 141. One end of the first horizontal top rod 144 is connected to the first vertical support rod 142, and one end of the second horizontal top rod 145 is connected to the second vertical support rod 143. The other ends of both the first horizontal top rod 144 and the second horizontal top rod 145 are provided with hinged portions. In actual manufacturing, the auxiliary support 14 can be made of metal and formed through processes such as stamping and bending to ensure its strength and stability.

[0038] The auxiliary bracket 14 is located at the rotatable connection between the second connector 13 and the cover plate 11 and is rotatable. Specifically, the nut of the screw has a connecting hole, and the hinge part of the auxiliary bracket 14 is engaged in the connecting hole. Multiple abutment grooves 111 are spaced apart along the height direction on the back of the cover plate 11. The transverse bottom rod 141 abuts against different abutment grooves 111, and the cover plate 11 is at different angles. When the bracket function is needed, the auxiliary bracket 14 is unfolded, and the transverse bottom rod 141 abuts against the abutment grooves 111, providing support for the cover plate 11 and effectively enhancing its stability, preventing shaking or displacement during use. For example, when watching instructional videos, the tablet computer playing the video can be placed on the front of the cover plate 11 and adjusted to a suitable tilt angle. This allows the user to watch the instructional video on the electronic device and then follow along with the practical operations on the computer connected to the keyboard. Simultaneously, the auxiliary bracket 14 is unfolded and abuts against the appropriate abutment groove 111, making the cover plate 11 more stable.

[0039] The bottom edge of the front of the cover plate 11 is provided with a storage groove 114. A pull-out limiting plate 1141 is movably installed in the storage groove 114, that is, the pull-out limiting plate 1141 can be pulled out of the storage groove 114 or pushed into the storage groove 114. For example, when the cover plate 11 is needed to protect the keyboard, the pull-out limiting plate 1141 is fully pushed into the storage groove 114 and then the cover plate 11 is closed. This avoids interference caused by the pull-out limiting plate 1141. When the cover plate 11 is needed to function as a support, the pull-out limiting plate 1141 is pulled out part of the storage groove 114, and the electronic device is placed on top of the pull-out limiting plate 1141, whereby the pull-out limiting plate 1141 serves as a support.

[0040] It should be noted that the pull-out limiting plate 1141 and the storage slot 114 can be slidably engaged by means of a track or gears, which will not be elaborated here.

[0041] As shown in Figure 4, the front edge of the cover plate 11 is provided with several magnetic suction pieces 112. When the cover plate 11 is used as a stand, a tablet computer with a built-in magnet can be placed on the front of the cover plate 11, and the tablet computer will be magnetically attracted by the magnetic suction pieces 112, thereby improving the stability of the tablet computer. Furthermore, the pull-out limiting plate 1141 can be partially pulled out from the storage slot 114 to support the tablet computer, further improving the stability of the placement. When the cover plate 11 is used to protect the keyboard body, after the cover plate 11 is closed, the magnetic suction pieces built into the keyboard body 2 on the cover plate 11 magnetically attract each other. The magnetic suction pieces built into the keyboard body 2 can be magnets or iron sheets, etc.

[0042] As shown in Figure 4, the front of the cover plate 11 is provided with a groove 113. When the cover plate 11 is closed relative to the keyboard body 2, the keys on the front of the keyboard body 2 are stored in the groove 113, which further improves the protection effect and prevents the keys from being squeezed.

[0043] In summary, this utility model, through the cooperation of the first connector 12 and the second connector 13 with the cover plate 11, enables the cover plate 11 to open and close at multiple angles and be stored. It not only protects the keyboard but also functions as a support, greatly improving its flexibility and adapting to the protection and operation needs of the keyboard in different usage scenarios. Furthermore, the auxiliary support 14 can be unfolded to form a stable support, effectively enhancing the stability of the cover plate 11 and preventing shaking or displacement during use. At the same time, the auxiliary support 14 can be rotated and retracted without affecting the folding and storage of the cover plate 11, balancing practicality and portability.

[0044] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
