The inner side of the hollow plate 1 is installed with a heat dissipation mechanism 2, which is used to dissipate heat from the seat; the top front side of the armrest 3 is rotatably connected with a knob 12, and the end of the knob 12 passes through the armrest 3 and is fixedly connected to the top of the driving pulley 11; a pillow 5 is installed at the middle and upper part of the front side of the back plate 4; a lumbar support 6 is installed at the middle and lower part of the front side of the back plate 4;

[0031] Specifically, the user will sit on a special hollow board 1; a soft cushion is designed on the top of the hollow board 1, and the addition of this cushion significantly improves the comfort of the seat; in order to realize the rotation function of the seat, a rotating knob 12 is set, and when automatic adjustment is required, the knob 12 can be replaced with a motor for use, which is directly connected to the driving pulley 11; when the knob 12 is rotated, the driving pulley 11 will also start; the operation of this driving pulley 11 is not isolated, it is connected to the driven pulley 16 through a connecting belt 13, so that the rotation of the two can be synchronized; the start of the driven pulley 16 drives the driving bevel gear 15 Synchronous rotation; the rotation of the active bevel gear 15 is meshed with the driven bevel gear 14, thereby transmitting power to the driven bevel gear 14, causing it to start rotating; the rotation of the driven bevel gear 14 is not just a simple rotation, it also drives the synchronous angle adjustment of the fixing rod 17, so that the angle adjustment function of the backrest 4 can be realized; the user can lean on the backrest 4 during the whole process, so that the user can feel in real time whether the adjustment angle of the chair meets the personal comfort needs; when the user leans on the backrest 4, the pillow 5 will provide support for the user's neck and head, and the lumbar support 6 will provide necessary support for the waist. These designs are to ensure the comfort and health of the human body under long-term use.

[0032] Reference Figure 1 and Figure 3The heat dissipation mechanism 2 includes a driving motor 203, the rear side of the driving motor 203 is fixedly connected to the inner front side of the hollow plate 1, the output end of the driving motor 203 is fixedly connected to a mounting rod 206, the outer wall of the mounting rod 206 is equidistantly fixedly connected to a plurality of worms 205, the right end of the inner bottom of the hollow plate 1 is equidistantly rotatably connected to a plurality of worm gears 204, the top of the worm gear 204 is installed with a fan blade 202, and the top wall of the hollow plate 1 is equidistantly provided with a plurality of heat dissipation holes 201; the front side of the hollow plate 1 is equidistantly provided with a plurality of through holes 18; the front side of the outer wall of the hollow plate 1 is threadedly connected with a bolt 7, and the hollow plate 1 is threadedly connected to the filter plate 8 through the bolt 7;

[0033] Specifically, the internal drive motor 203 starts working, and it is responsible for driving the mounting rod 206 to rotate; this mounting rod 206 does not act alone, and its rotation will drive multiple worm gears 205 to rotate synchronously; the rotation of these worm gears 205 is engaged with the worm wheel 204, and then the worm wheel 204 and the fan blades 202 are driven to rotate together; the rotation of the fan blades 202 realizes the circulation of air through the through hole 18, and at the same time, the airflow is emitted through the heat dissipation hole 201, which can effectively dissipate the heat at the buttocks of the user of the chair; this design avoids the stuffy discomfort that may be caused by sitting on the chair for a long time; in addition, when the airflow passes through the through hole 18, it also needs to be filtered through the filter plate 8 to ensure the cleanliness of the airflow; if the filter plate 8 needs to be maintained or replaced, it can be removed by bolts 7.

[0034] Reference Figure 1 The bottom of the hollow plate 1 is fixedly connected with a support leg 9, and the end of the support leg 9 is installed with a universal wheel 10;

[0035] Specifically, through the cooperation of the supporting legs 9 and the universal wheels 10, the chair can be supported and moved at the same time.

[0036] Working principle: When using the gaming chair, sit on the hollow plate 1. The top of the hollow plate 1 is provided with a soft cushion to increase the comfort. The rotating knob 12 rotates the driving pulley 11. The rotation of the driving pulley 11 is linked to the driven pulley 16 through the connecting belt 13 to rotate synchronously. The rotation of the driven pulley 16 drives the driving bevel gear 15 to rotate synchronously. The rotation of the driving bevel gear 15 is meshed with the driven bevel gear 14 to drive the driven bevel gear 14 to rotate. The driven bevel gear 14 and the fixing rod 17 are synchronously adjusted to adjust the angle of the back plate 4.

[0037] When using the gaming chair, the driving motor 203 is turned on to drive the mounting rod 206 to rotate. The rotation of the mounting rod 206 causes multiple worms 205 to rotate synchronously. The rotation of the worm 205 is meshed with the worm wheel 204, thereby driving the worm wheel 204 and the fan blades 202 to rotate synchronously. The air is circulated through the through hole 18, and the airflow passes through the heat dissipation hole 201 to dissipate the heat at the user's buttocks, avoiding the stuffiness caused by sitting on the chair for a long time. At the same time, the airflow is filtered by the filter plate 8 when passing through the through hole 18, and the filter plate 8 can be disassembled later by the bolt 7.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
