[0007] To achieve the above object, the present utility model provides the following technical solutions: An electric lifting and standing-up multifunctional nursing chair, comprising a base and universal wheels provided on the front side of the base, a driving wheel is provided on the rear side of the base, a battery is provided in the middle of the base, and a lifting base is provided on the upper end of the base; an auxiliary standing-up mechanism is provided on the lifting base, a frame body is hingedly installed at the front end of the auxiliary standing-up mechanism, the rear end of the frame body is hinged to the output end of a second electric push rod, the other end of the second electric push rod is hinged to the lower end inside the lifting base, and a seat cushion is provided on the auxiliary standing-up mechanism, and the lower end of the seat cushion is fixedly installed on the upper end of the frame body; a height adjustment mechanism is provided between the lifting base and the base, the height adjustment mechanism is provided with a first electric push rod, the output end of the first electric push rod is hingedly installed inside the lifting base, the other end of the first electric push rod is hingedly installed on the upper end of the base, the height adjustment mechanism includes vertical guide posts fixedly installed on both sides of the upper end of the base, and a guide tube is nested on the upper end of the guide post, and the upper end of the guide tube is fixedly installed on the lower end of the lifting base.

[0008] Further, a second electric push rod is hingedly installed below the rear end of the frame body, and the lower end of the second electric push rod is hingedly arranged inside the lifting base.

[0009] Further, guide posts are fixedly installed on the upper end of the base, a guide tube is nested on the upper end of the guide post, and the upper end of the guide tube is fixedly installed on the lower end of the lifting base.

[0010] Further, the output end of the first electric push rod is hingedly installed at the lower end of the lifting base, a footrest plate is rotatably installed at the front end of the lifting base, a footrest adjustment mechanism is provided at the lower end of the lifting base, and the footrest adjustment mechanism is connected to the footrest plate.

[0011] Further, a footrest is provided at the front end of the lifting base, and the bottom of the footrest is rotatably arranged.

[0012] Further, a soft cushion backrest is rotatably installed at the rear end of the lifting base, a gas spring is rotatably arranged in front of the bottom of the soft cushion backrest, a backrest adjustment handle is provided at the front end of the gas spring, and the upper end of the backrest adjustment handle is fixedly installed at the lower end of the lifting base.

[0013] Further, a liftable and movable armrest is fixedly installed on the upper end of the lifting base, the number of armrests is two, and a controller is provided at the front end of the right armrest.

[0014] Compared with the prior art, the beneficial effects of the present utility model are:

[0015] 1. A driving wheel capable of driving movement is provided at the rear end of the base of the device, driving the device to rotate and adjust the angle under the guidance of the universal wheels. The footrest position of the foot pedal can rotate, and a soft cushion backrest capable of adjusting the position is provided at the rear end of the lifting base. The soft cushion backrest can adjust the angle between the sitting position and the lying position under the cooperation of the backrest adjustment handle and the gas spring. At the same time, the footrest board is adjusted to the horizontal or vertical state by the footrest board adjustment mechanism, and the user can switch the nursing chair between the sitting position and the lying flat position;

[0016] Further, when an elderly user uses it, if the elderly user turns over from the bed onto the nursing chair, since the height of the lying flat surface of the nursing chair and the height of the bed surface may not be horizontal, it is difficult for the elderly user to get onto the nursing chair. At this time, first adjust the footrest board to the horizontal position and the soft cushion backrest to the lying flat position, so that the nursing chair is in the lying flat state. Then, through the cooperation of the first electric push rod, the guide post and the catheter, the height of the nursing chair can be adjusted and controlled while maintaining a stable lying flat state. Under the operation of the first electric push rod, the lifting base drives the height of the nursing chair to be adjusted so as to be at the same height as the bed surface, facilitating the elderly user to turn over from the bed onto the nursing chair;

[0017] 2. The frame is hinged to the front end position of the lifting base. Therefore, the seat cushion provided at the upper end of the frame can be synchronized to be horizontal or inclined under the action of the frame. When an elderly person with difficulty getting up uses this nursing chair, first use the footrest board adjustment mechanism to adjust the footrest board to the vertical state and fold the foot pedal, so that the elderly user's feet touch the ground. At the same time, reset the angle of the soft cushion backrest at the rear end to the sitting position, making the whole nursing chair in the sitting position; when wanting to get up, by starting the second electric push rod, the frame and the seat cushion tilt forward and rotate, which can lift the buttocks of the elderly person to assist the elderly user to get up, thus saving the physical consumption of the elderly user and making it more convenient to get up and use.
