The shapes of the backrest frame 31 and the sponge 32 are respectively set with reference to the shape of the human back. The structure of the backrest frame 31 improves the support and stability of the backrest 3, which is composed of the rear plate 311 and the two side plates 312. The rear plate 311 is used to support the overall structure of the backrest 3; the side plates 312 are located on both sides of the rear plate 311, and both side plates 312 are located on the front side of the rear plate 311, forming a U-shaped structure with the rear plate 311. The side plates 312 and the rear plate 311 are detachably arranged, which is convenient for production and manufacturing. The sponge 32 is a high-elastic sponge 32, which is partially embedded between the two side plates 312 and partially protrudes forward relative to the side plates 312. The use of the high-elastic sponge 32 ensures the softness and comfort of the backrest 3, so that users are not prone to fatigue during long-term use. The overall support of the backrest 3 is improved through the combination of the rear plate 311 and the side plates 312 of the backrest frame 31. This design makes the backrest 3 stronger and able to withstand greater loads, thus providing a better support effect.

[0031] Please refer to Figure 1 , the electric chair further includes a leg rest bracket 9. The leg rest bracket 9 is used to install a leg rest plate (not shown in the figure), and the leg rest plate is used to support the user's legs. Please refer to Figure 3 and Figure 4 , the base 1 includes a base 11, a main rod 12, a seat plate 13, a leg rest drive mechanism 14 and a leg rest telescopic mechanism 15.

[0032] The base 11 is used to be placed on the ground to support other components of the electric chair. The main rod 12 is installed on the base 11. The main rod 12 is a long bar-shaped member structure, which is placed horizontally relative to the ground and is installed on the base 11 at the middle position.

The leg rest telescopic mechanism 15 is movably installed on the seat plate 13 and is connected to the output end of the leg rest drive mechanism 14. The leg rest bracket 9 is installed at one end of the leg rest telescopic mechanism 15 close to the front of the seat plate 13. When the leg rest drive mechanism 14 drives the leg rest telescopic mechanism 15 to extend, the leg rest telescopic mechanism 15 can drive the leg rest bracket 9 to lift, so that the leg rest bracket 9 can support the user's legs.

[0033] Please refer to Figure 3 and Figure 4, the base 1 further includes a backrest driving mechanism 16 and a backrest adjusting mechanism 17. The backrest driving mechanism 16 is installed on the main rod 12, and the backrest adjusting mechanism 17 is movably installed on the seat plate 13 and connected to the output end of the backrest driving mechanism 16. The backrest 3 is installed on the backrest adjusting mechanism 17, and the backrest driving mechanism 16 can adjust the angle between the backrest 3 and the seat plate 13 through the backrest adjusting mechanism 17. The leg rest driving mechanism 14 and the backrest driving mechanism 16 are different driving mechanisms and can be controlled independently; the leg rest driving mechanism 14 and the backrest driving mechanism 16 act on the leg rest telescoping mechanism 15 and the backrest adjusting mechanism 17 respectively, so that the leg rest bracket 9 and the backrest 3 bracket can be adjusted independently.

[0034] When the leg rest driving mechanism 14 drives the leg rest telescoping mechanism 15 to extend, the leg rest telescoping mechanism 15 can drive the leg rest bracket 9 to lift, so that the leg rest plate installed on the leg rest bracket 9 can support the user's legs. When the leg rest driving mechanism 14 drives the leg rest telescoping mechanism 15 to contract, the leg rest telescoping mechanism 15 can drive the leg rest bracket 9 to retract. When the backrest driving mechanism 16 drives the backrest adjusting mechanism 17 to rotate forward with respect to the seat plate 13, the backrest adjusting mechanism 17 can drive the backrest 3 to tilt backward (increase the angle between the backrest 3 and the seat plate 13). When the backrest driving mechanism 16 drives the backrest adjusting mechanism 17 to rotate backward with respect to the seat plate 13, the backrest adjusting mechanism 17 can drive the backrest 3 to rotate forward (decrease the angle between the backrest 3 and the seat plate 13). In practical applications, the user can independently control the leg rest driving mechanism 14 to independently control the lifting or retraction of the leg rest bracket 9; or can independently control the backrest driving mechanism 16 to independently adjust the angle of the backrest 3; or can also control the leg rest driving mechanism 14 and the backrest driving mechanism 16 simultaneously to adjust the leg rest bracket 9 and the backrest 3 simultaneously.

[0035] In this technical solution, the leg rest driving mechanism 14, the leg rest telescoping mechanism 15, the backrest driving mechanism 16 and the backrest adjusting mechanism 17 are simultaneously arranged on the seat plate 13, so that the leg rest bracket 9 and the backrest 3 can be independently controlled, meeting the requirements of independent adjustment of the leg rest bracket 9 and the backrest 3 during use. Moreover, through the arrangement of the leg rest telescoping mechanism 15 and the backrest adjusting mechanism 17, the structure of the telescoping or adjusting mechanism is simplified.

[0036] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
