[0030] Please refer to Figure 1-2 The automatic height-adjustable chair includes a height adjustment assembly 4, a position adjustment assembly 5 mounted on top of the height adjustment assembly 4, a support foot assembly 6 mounted at the bottom of the height adjustment assembly 4, a seat cushion 2 mounted on top of the position adjustment assembly 5, and a backrest 1 rotatably connected to the height adjustment assembly 4. The backrest 1 is composed of two frames with different curvatures connected together, thus better conforming to the angle of the human back and improving comfort. Rotating the backrest 1 adjusts the angle of the backrest 1 relative to the seat cushion 2; adjusting the height adjustment assembly 4 adjusts the height of the seat cushion 2 relative to the ground; and adjusting the position adjustment assembly 5 adjusts the distance between the seat cushion 2 and the desk, as well as fine-tuning the height between the seat cushion 2 and the position adjustment assembly 5. A symmetrical armrest 3 is mounted on both sides of the seat cushion 2, providing support for the student's arms during use.

[0031] Please refer to Figure 1-4 The support leg assembly 6 includes a connecting frame 61 and a support frame 63 surrounding the connecting frame 61. The connecting frame 61 is connected to the height adjustment assembly 4. A mounting groove 62 is formed around the outer wall of the connecting frame 61. The support frame 63 is fixedly installed inside the mounting groove 62. A pulley 64 is rotatably mounted on the bottom of the support frame 63. The pulley 64 can rotate around the support frame 63. The movement of the seat is achieved through the sliding of the pulley 64 itself and its rotation relative to the support frame 63.

[0032] Please refer to Figure 1-5The height adjustment assembly 4 includes a height adjustment frame 41, an adjustment rod 43 movably mounted on the height adjustment frame 41, a pneumatic rod 47 penetrating the height adjustment frame 41, and a lifting rod 49 engaged with the position adjustment assembly 5. The height adjustment frame 41 is horizontally positioned, with a lifting hole 46 in the middle, and the pneumatic rod 47 is installed inside the lifting hole 46. The connecting frame 61 is connected to the pneumatic rod 47, which has a piston inside and is filled with compressed gas. Pressing the pneumatic rod 47 raises or lowers it, thereby raising or lowering the height adjustment frame 41 relative to the connecting frame 61, ultimately adjusting the height of the seat cushion 2. The height adjustment frame 41 has an adjustment groove 42, and the middle of the adjustment rod 43 is rotatably mounted on the height adjustment frame 41. One end of the adjustment rod 43 extends outward along the adjustment groove 42, and an adjustment handle 45 is connected to the end of the adjustment rod 43. A pressing head 44 is provided at one end of the adjusting rod 43 near the gas spring 47, and the pressing head 44 can abut against the gas spring 47 downwards. In use, pressing the adjusting handle 45 can rotate the adjusting rod 43, thereby driving the pressing head 44 at the other end of the adjusting rod 43 to press the gas spring 47. After being pressed, the gas spring 47 rises and falls relative to the connecting frame 61, thereby adjusting the height of the seat cushion 2. A lifting hole 48 is provided on one side of the height adjusting frame 41, and a lifting rod 49 is threaded into the lifting hole 48. The lifting rod 49 is located on the side of the seat cushion 2 away from the backrest 1. A lifting head 410 is provided at the top of the lifting rod 49, and the lifting head 410 is embedded inside the position adjusting assembly 5. The upper diameter of the lifting rod 49 is larger than its lower diameter. A lifting spring 411 is fitted around the outside of the lifting rod 49. The lifting spring 411 abuts against the bottom of the height adjustment frame 41 and the upper bottom wall of the lifting rod 49, thus providing elasticity for the lifting rod 49. By rotating the lifting rod 49, the height of the lifting rod 49 relative to the height adjustment frame 41 can be changed. Ultimately, the lifting head 410 drives the position adjustment component 5 to make a fine adjustment of its position relative to the height adjustment frame 41, thereby allowing the height of the seat cushion 2 to be finely adjusted.

[0033] Please refer to Figure 1-3 and Figure 6The position adjustment assembly 5 includes a position adjustment frame 51, an adjustment rod 52, and limiting strips 54 on both sides of the position adjustment frame 51. The position adjustment frame 51 is adjustablely mounted on top of the height adjustment frame 41. A mating hole 58 is provided on the position adjustment frame 51 corresponding to the position of the lifting rod 49. The lifting rod 49 passes through the mating hole 58, and a lifting head 410 is engaged inside the mating hole 58 on the position adjustment frame 51. During the lifting and lowering process of the lifting rod 49, the position of the position adjustment frame 51 relative to the height adjustment frame 41 can be finely adjusted synchronously through the engagement of the lifting head 410. The adjustment rod 52 is arranged around the position adjustment frame 51, and an adjustment head 53 is provided at each end of the adjustment rod 52, with the adjustment heads 53 positioned inward relative to the adjustment rod 52. Multiple limiting slots 55 are provided on the limiting strips 54, and the adjustment rod 52 is engaged in the limiting slots 55. Specifically, the adjustment heads 53 are engaged inside the limiting slots 55. Each side of the position adjustment frame 51 is connected to a structural plate 56, which can move along the position adjustment frame 51. An adjustment pin 59 is installed on the structural plate 56. An adjustment rod 52 has a through hole in its middle, through which the adjustment pin 59 passes. A torsion spring 57 is installed on the adjustment pin 59. A mounting hole is provided on the adjustment rod 52 at a position corresponding to the torsion spring 57. One end of the torsion spring 57 abuts against the bottom wall of the position adjustment frame 51, and the other end of the torsion spring 57 is engaged in the mounting hole on the adjustment rod 52. When it is necessary to adjust the distance between the seat cushion 2 and the desk, first rotate the adjusting rod 52 so that the adjusting rod 52 rotates relative to the adjusting pin 59. After the adjusting heads 53 at both ends of the adjusting rod 52 disengage from the limiting slots 55 on the limiting strip 54, pull the adjusting rod 52 horizontally to adjust the distance of the seat cushion 2. After the distance is fully adjusted, under the action of the torsion spring 57, the adjusting rod 52 rotates back to its original position, and the adjusting heads 53 re-engage into the limiting slots 55, thus preventing the seat cushion 2 from shifting during use.

[0034] During use of the automatic height-adjustable chair, students can adjust the height of the seat cushion 2 relative to the ground, the distance between the seat cushion 2 and the desk, and the height of the seat cushion 2 itself according to their different needs for studying or resting, to meet different usage requirements. To adjust the height of the seat cushion 2 relative to the ground, press the adjustment handle 45 to rotate the adjustment rod 43, which in turn drives the pressing head 44 at the other end of the adjustment rod 43 to press the gas spring 47. Once the gas spring 47 is pressed, it can be raised or lowered relative to the connecting frame 61 to complete the adjustment. To adjust the distance between the seat cushion 2 and the desk, rotate the adjustment lever 52. When the adjustment head 53 disengages from the limiting slot 55 on the limiting strip 54, pull the adjustment lever 52 horizontally to adjust the distance of the seat cushion 2. After the distance is fully adjusted, under the action of the torsion spring 57, the adjustment lever 52 rotates back to its original position, and the adjustment head 53 re-engages into the limiting slot 55, completing the distance adjustment. When fine-tuning the height of the seat cushion 2, the lifting rod 49 is rotated to change the height of the lifting rod 49 relative to the height adjustment frame 41. The lifting head 410 then drives the position adjustment component 5 to fine-tune the position relative to the height adjustment frame 41, thus completing the fine-tuning of the height of the seat cushion 2.

[0035] By rotating the adjusting rod 43 to press the gas spring 47, the gas spring 47 is raised and lowered relative to the connecting frame 61, thus adjusting the height of the seat cushion 2 relative to the ground. By pulling the adjusting rod 52, the adjusting rod 52 is engaged in different limit slots 55, thus adjusting the distance between the seat cushion 2 and the desk. By raising and lowering the lifting rod 49, the height of the position adjusting frame 51 relative to the height adjusting frame 41 is changed, thus fine-tuning the height of the seat cushion 2 itself. In this way, the height and angle of the seat can be adjusted according to the different needs of different students for studying and resting, further expanding the adjustable range of the seat.
