[0002] Traditional chairs for the elderly often only allow for single-angle adjustment of the backrest or leg rest, while the seat itself remains fixed. This means the user's buttocks and thighs are always on the same plane, making it impossible to make overall, segmented, and precise adjustments to the buttocks, thighs, calves, torso, and elbows according to individual needs. Furthermore, the elbow support is usually manually adjustable or non-adjustable, making it difficult to automatically follow changes in posture during motorized movements, thus affecting comfort and safety.

[0003] Therefore, it is essential to design an adjustable, multi-functional chair for the elderly to improve their comfort. Utility Model Content

The connecting column 2 is set horizontally.

[0024] A rotatable seat plate 3 is provided above the fixed frame 1. Connecting blocks 4 are fixedly connected to both ends of the seat plate 3 along the width direction on the side of the seat plate 3 near the connecting column 2. The two connecting blocks 4 are provided with round holes that are compatible with the connecting column 2, so that the connecting blocks 4 are fitted on the connecting column 2 and rotatably connected to the connecting column 2, thereby allowing the seat plate 3 to rotate around the connecting column 2.

[0025] Two electric telescopic cylinders 5 are installed on the side of the seat plate 3 away from the connecting column 2. The two electric telescopic cylinders 5 are respectively located on both sides of the seat plate 3 along the width direction. A fixing plate 6 is fixedly connected to the lower side of the fixing frame 1. The fixed ends of the two electric telescopic cylinders 5 are hinged to the fixing plate 6. The output ends of the two electric telescopic cylinders 5 are hinged to the side of the seat plate 3 away from the connecting column 2. In this way, the seat plate 3 is controlled to rotate by the electric telescopic cylinders 5. At the same time, the electric telescopic cylinders 5 provide pressure support for the seat plate 3. When a person sits on the seat plate 3, the electric telescopic cylinders 5 provide pressure support for the seat plate 3.

[0026] A back plate 7 is hinged to the end of the seat plate 3 away from the connecting column 2. A connecting frame 8 is fixedly connected to the lower side of the seat plate 3. The connecting frame 8 is a frame with a right-angled triangular cross-section. An electric telescopic cylinder 9 is provided on the side of the connecting frame 8 away from the connecting column 2. The electric telescopic cylinder 9 is located at the center of the connecting frame 8 along the width direction of the seat plate 3. The fixed end of the electric telescopic cylinder 9 is hinged to the lower end of the connecting frame 8, and the output end of the electric telescopic cylinder 9 is hinged to the back plate 7. In this way, the back plate 7 is rotated relative to the seat plate 3 by the electric telescopic cylinder 9.

[0027] A rotatable leg plate 10 is provided at one end of the seat plate 3 near the connecting column 2. A bushing 11 is fixedly connected to one end of the leg plate 10 near the seat plate 3.

[0029] The inner arc surface of the arc plate is fixedly connected to a matching arc-shaped toothed rack 17.

[0030] Since the elbow plate 15 can rotate, the arc plate rotates with the elbow plate 15. Therefore, the seat plate 3 has a through hole corresponding to the arc plate, and one end of the arc plate passes through the through hole without contacting the inner wall of the through hole.

[0031] A horizontally set fixed plate 18 is fixedly connected to the connecting frame 8. A dual-axis drive motor 19 is fixedly connected to the fixed plate 18. Gears 20 are fixedly connected to the output ends of the dual-axis drive motor 19. The gears 20 mesh with the arc-shaped rack 17. The dual-axis drive motor 19 drives the arc-shaped plate to rotate through the gears 20, thereby adjusting the rotation angle of the elbow plate 15.

[0032] The outer sides of the seat 3, backrest 7, legrest 10, and elbow rest 15 may be covered with an outer material that is soft and breathable to enhance the user experience.

[0033] The exterior material can be a composite material, such as high-resilience breathable sponge + linen or cotton-linen blended composite fabric, microfiber leather perforated composite layer (microporous microfiber leather on the surface + high-permeability bubble cotton), bamboo charcoal fiber knitted fabric, and cooling gel memory sponge covered with ice silk fabric, etc.

[0034] The outside of the mounting bracket 1 can be covered with a protective sleeve to prevent the internal structure of the mounting bracket 1 from being exposed, thereby enhancing the aesthetics and protecting the mounting bracket 1 and its internal structure.

[0035] The electric recliner is equipped with a remote control. Electric telescopic cylinder 1 (5), electric telescopic cylinder 2 (9), electric telescopic cylinder 3 (13), and dual-axis drive motor 19 are all connected to the remote control signal. The remote control controls the driving process of electric telescopic cylinder 1 (5), electric telescopic cylinder 2 (9), electric telescopic cylinder 3 (13), and dual-axis drive motor 19, allowing the user to adjust the posture of the seat 3, backrest 7, leg rest 10, and elbow rest 15 to meet the user's requirements.

[0036] In this embodiment, the angle of the user's buttocks and thighs relative to the knees is adjusted by controlling the electric telescopic cylinder 5 to drive the seat plate 3 and connecting column 2.

[0037] By controlling the electric telescopic cylinder 29 to drive the back panel 7 to adjust the angle relative to the seat panel 3, the posture of the user's torso relative to the buttocks can be adjusted.

[0038] By controlling the electric telescopic cylinder 313 to drive the leg plate 10 to adjust the angle relative to the connecting column 2, the posture of the user's lower leg relative to the knee can be adjusted.

[0039] The dual-axis drive motor 19 drives the arc-shaped plate and elbow plate 15 to rotate, thereby adjusting the posture of the user's elbow relative to the torso.
