[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the protection scope of the present invention.

[0021] Please refer to Figures 1-4 , the present invention provides a technical solution:

[0022] A wireless keyboard with an adjustable bracket structure includes a keyboard body 1. A worm 2 is rotatably installed on one inner wall of the keyboard body 1. One end of the worm 2 penetrates through the keyboard body 1 and is fixedly connected to an adjusting knob 3. A worm gear 4 is engaged with the bottom of the worm 2. A rotating rod 5 is fixedly inserted into the interior of the worm gear 4. Linkage assemblies 6 for adjusting the inclination angle of the keyboard body 1 are respectively arranged at both ends of the rotating rod 5. The present invention can adjust the inclination angle of the keyboard body 1. Users can freely adjust the inclination angle of the keyboard body 1 according to their own usage habits and desktop height, so as to find the most suitable typing posture. This design not only helps to improve typing efficiency, but also effectively alleviates the hand fatigue and discomfort caused by long-term use of the keyboard;

[0023] It should be noted that the interior of the keyboard body 1 is equipped with wireless communication modules such as a Bluetooth chip or a 2.4GHz wireless transmitter. These modules are responsible for converting the input signals of the keyboard body 1 into wireless signals and sending and receiving them. When the user presses a key on the keyboard body 1, the circuit inside the keyboard body 1 will capture this action and convert it into a digital signal. Then, the wireless communication module encodes these digital signals and sends them wirelessly (such as via Bluetooth or the 2.4GHz frequency band). For a wireless keyboard using Bluetooth technology, it will pair and connect with a receiving device (such as a computer, tablet, or mobile phone) through the Bluetooth protocol. Once the pairing is successful, the keyboard body 1 can communicate with the device through Bluetooth wireless signals to achieve data transmission;

[0024] A wireless keyboard using 2.4GHz technology communicates using the 2.4GHz frequency band. The 2.4GHz wireless transmitter inside the keyboard body 1 sends signals to the corresponding receiver, and the receiver then converts these signals into input instructions that the computer can recognize. To receive the signals emitted by the keyboard body 1, usually a receiver matching the keyboard is required. This receiver can be inserted into the USB interface of the computer and is responsible for receiving the wireless signals and converting them into instructions that the computer can understand;

[0025] The linkage component 6 includes a crown gear 601. The crown gear 601 is fixedly connected to one end of the rotating rod 5. A spur gear 602 is meshed on one side of the crown gear 601. A lead screw 603 is fixedly inserted inside the spur gear 602. The top end of the lead screw 603 is rotatably installed on the inner top of the keyboard body 1, and the bottom end of the lead screw 603 is rotatably installed on the inner bottom of the keyboard body 1;

[0026] It also includes a moving block 604. The moving block 604 is threadedly connected to the outer wall of the lead screw 603. Two groups of support rods 605 are symmetrically and fixedly connected to the bottom of the moving block 604. The bottom ends of the two groups of support rods 605 penetrate through the keyboard body 1 and are fixedly connected to a support plate 606. The bottom of the support plate 606 is arc-shaped;

[0027] Two groups of through holes adapted to the support rods 605 are symmetrically opened on the inner bottom of the keyboard body 1. The two groups of support rods 605 are respectively slidably inserted into the two groups of through holes;

[0028] Specifically, when the user manually rotates the adjustment knob 3, the worm 2 can be driven to rotate, thereby driving the worm wheel 4 to rotate, further driving the rotating rod 5 to rotate, driving the crown gear 601 to rotate, then driving the spur gear 602 to rotate, thus driving the lead screw 603 to rotate, causing the moving block 604 to reciprocate along the axial direction of the lead screw 603, and further adjusting the inclination angle of the keyboard body 1 through the support rods 605 and the support plate 606;

[0029] An installation plate 7 is fixedly installed on the inner top of the keyboard body 1. One end of the worm 2 away from the adjustment knob 3 is rotatably installed on the side wall of one side of the installation plate 7. By setting the installation plate 7, it plays a role in supporting and positioning the worm 2;

[0030] Two groups of rotating seats 8 are symmetrically and fixedly connected to the inner top of the keyboard body 1. The rotating rod 5 is rotatably connected to the two groups of rotating seats 8. By setting the rotating seats 8, it plays a role in supporting and positioning the rotating rod 5;

[0031] Three anti-slip pads 9 are fixedly connected to the bottom of the keyboard body 1. The three anti-slip pads 9 are arranged at equal intervals. The main purpose of the design of the anti-slip pads 9 is to increase the friction between the keyboard body 1 and the desktop, so as to ensure that the keyboard body 1 can remain stable during use and is not easy to slide. This stability is particularly important for activities that require precise operations such as typing and gaming, and can effectively prevent misoperations caused by the displacement of the keyboard body 1;

[0032] And a hand rest 10 is detachably installed on one side wall of the keyboard body 1. The presence of the hand rest 10 can provide additional support for the hand, reduce the pressure distribution of the hand during typing, especially in the case of long-term use of the keyboard, it can significantly reduce the fatigue of the hand and improve the comfort of use.

[0033] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
