[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0027] like Figure 1-4 As shown, the present invention proposes an adjustable support structure for a reclining desk and chair. The desk leg mechanism includes a main desk leg frame 11, on which a movable auxiliary desk leg frame 12 is installed. The two are fixed together by a desk leg limiting bolt 13.

[0028] The table drawer mechanism includes a first motor 21 mounted on the table leg support 12. The output end of the first motor 21 is connected to a table drawer shaft 22 that passes through the table leg support 12. The outer wall of the table drawer shaft 22 is fitted with a table drawer 23.

[0029] The chair leg mechanism includes a main chair leg frame 31, on which a movable auxiliary chair leg frame 32 is mounted. The two are fixed together by a chair leg limiting bolt 33, and a seat plate 4 is held between the auxiliary chair leg frames 32.

[0030] The leg support mechanism includes a track 51 symmetrically installed at the bottom of the seat plate 4. A sliding slide 52 is installed in the track 51. The slide 52 is connected to the leg support frame 54 through a connecting rod 53. A flip rod 55 is held between the leg supports 54. A leg support 56 is sleeved on the outside of the flip rod 55.

[0031] The chair back mechanism includes a chair back frame 61 symmetrically installed on the lower part of the seat plate 4. A second motor 62 is provided on the chair back frame 61. The output end of the second motor 62 is connected to a chair back shaft 63 that passes through the chair back frame 61. A chair back support rod 64 is sleeved on the outside of the chair back shaft 63. A movable chair back tube 65 is connected to the chair back support rod 64. A chair back 66 is connected to the back of the chair back tube 65.

[0032] It should be noted that the table drawer 23 rotates with the table drawer shaft 22 driven by the first motor 21, and the opening of the table drawer 23 is always tilted upward; when the table drawer 23 rotates, the always upward opening can prevent the books placed in the table drawer 23 from falling out.

[0033] In this embodiment, the table drawer mechanism and the chair back mechanism are improved. Both are driven by motors to rotate their respective shafts, eliminating the need to manually adjust the angles of the table drawer 23 and the chair back 66 before resting, thus avoiding the tedious steps of manual adjustment.

[0034] The table drawer 23 rotates along the table drawer shaft 22 driven by the first motor 21, and the chair back 66 rotates along the chair back shaft 63 driven by the second motor 62. The chair back 66 rotates at the same angle as the table drawer 23, and the two rotate in opposite directions. After rotation, the table drawer 23 and the chair back 66 are attached to each other. The tilted table drawer 23 tilts upward to reduce space occupation, and at the same time, it can help support the tilted chair back 66, preventing the chair back 66 from tipping over due to bearing the load alone, thus improving the safety of using the reclining desk and chair.

[0035] To facilitate arm support, the upper part of the chair leg support frame 32 is further formed with armrests, which are symmetrically arranged on both sides of the seat plate 4.

[0036] To further store the leg rest 56, the combined assembly of slide 52, connecting rod 53 and leg rest 54 moves linearly along the slot of track 51. When the leg rest 56 moves with the assembly to below the seat plate 4, it is stored in the gap between the two tracks 51.

[0037] Understandably, when the leg rest 56 is located below the seat plate 4, the leg rest 56 is relatively parallel to the seat plate 4. When the leg rest 56 protrudes from the seat plate 4, the angle of the leg rest 56 can be adjusted by using the flip rod 55.

[0038] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope.
