[0021] Please see Figure 1-3 This utility model provides a technical solution: an electric assistive chair for elderly people who have fallen, including a chassis support 1, a lifting main frame, and a movable seat plate 5. The lifting main frame is installed on the top of the chassis support 1. The lifting main frame includes two sets of front push rod motors 7 and two sets of rear push rod motors 11. The front push rod motors 7 are symmetrically and vertically installed at the top front end of the chassis support 1, and the rear push rod motors 11 are symmetrically and vertically installed at the top rear end of the chassis support 1. A secondary crossbar 1 8 and a secondary crossbar 3 10 are installed between the front push rod motors 7 and the rear push rod motors 11 and at their upper ends. The upper ends of the two rear push rod motors 11 are connected to a secondary crossbar 2 9. The movable seat plate 5 is laid flat on the inner side of the chassis support 1. When the four push rod motors are started simultaneously, they drive the entire lifting main frame to move upward, and during the upward movement, they drive the movable seat plate 5.

[0022] In a further improvement, the middle of the two rear push rod motors 11 is connected to a secondary crossbar 12 and a fixed rod 14. The fixed rod 14 is located below the secondary crossbar 12. A backrest 13 is connected between the fixed rod 14 and the secondary crossbar 12. Safety straps can be installed on the fixed rod 14 and the secondary crossbar 12. The safety straps can be fixed to the elderly person to improve safety during the lifting process.

[0023] In a further improvement, a main crossbar 3 is connected between the front push rod motor 7 and the rear push rod motor 11. Safety belts are symmetrically arranged on the main crossbar 3 and are connected to the movable seat plate 5. A switch 15 is installed on one of the main crossbars 3. The switch 15 controls the front push rod motor 7 and the rear push rod motor 11. The chair is connected to a 220V power supply and can also be powered by a lithium battery.

[0024] Further improvements include an upper seat belt 16, a lower seat belt 6, and a seat belt plug 2. The upper end of the upper seat belt 16 is fixedly connected to the main crossbar 3, and the lower end of the upper seat belt 16 is fixedly connected to the seat belt plug 2. The upper end of the lower seat belt 6 is connected to a seat belt insert, which is embedded in the seat belt plug 2. The lower end of the lower seat belt 6 is fixedly connected to the top edge of the movable seat plate 5. The seat belt is a car seat belt buckle, which is highly safe and easy to disassemble and install.

[0025] Further improvements include a U-shaped chassis support 1 with four casters 4 installed at the bottom, and the rear casters 4 being self-locking.

[0026] Further improvements include the addition of fixing rings 17 at both ends of the secondary crossbar 18, secondary crossbar 29, secondary crossbar 310, secondary crossbar 412, main crossbar 3, and fixing rod 14.
