detailed description

The device will be described in detail below in conjunction with the accompanying drawings.

As shown in Fig. 1 and Fig. 2, the utility model includes four parts, i.e. upper body regulation and control lifting structure 1, lower limbs regulation and control lifting mechanism 2, seat and armrest mechanism 3, lifting and roller mechanism 4; specifically for including a support frame 18 , the top of the support frame 18 is provided with a seat cushion, the front end of the support frame 18 is provided with a lower limb support pad, the rear end of the support frame 18 is provided with a backrest 9, both sides of the support frame 18 are provided with an armrest mechanism 15, and the bottom of the support frame 18 Drive wheels are provided; the backrest 9 realizes its up and down adjustment along the rear end of the seat cushion through the lifting mechanism I, and the described lower limb support pad realizes its up and down adjustment along the front end of the seat cushion through the lifting mechanism II; each part will be described respectively below :

The lifting structure of the upper body control as shown in Figure 3 includes: backrest 9, electric push rod 8, connecting pin 10, foldable U-shaped outrigger 6, foldable handle 5, gas spring 7; the power output end of electric push rod 8 drives the backrest 9 , and the both sides of electric push rod 1 are provided with gas spring 7 connecting backrest and support frame; At the same time, a foldable U-shaped leg 6 is provided at the bottom of the backrest.

As shown in Figure 4, the lower limbs control lifting mechanism includes: electric push rod 24, connecting pin shaft 23, leg support 11, foot support 12, telescopic rod 13, the power output end of electric push rod 24 drives leg support 11, and the leg support One end of 11 is connected with the front end of the support frame through connecting pin 23, and the opposite end is connected with foot support 12. The foot rest 12 and the leg rest 11 are hinged together, and the bottom of the foot rest 12 is connected with the bottom of the lower limb support pad through a telescopic rod 13 .

Seat and armrest mechanism comprises as Fig. 5: seat cushion 21, armrest 15, portable toilet 16, toilet slideway 17, armrest control device 14; Seat cushion 21 bottom is provided with a portable toilet 16, and described portable toilet The toilet 16 can slide back and forth along the toilet slideway 17 installed on the support frame; the two ends of the armrest 15 are connected on the support frame by two pin shafts, and the armrest 15 can be moved along the seat cushion under the control of the armrest control device 14 swing up and down on both sides.

The electric push rods 8, 24 and the support frame 18 are all connected to the control device, and the control button 22 is arranged on the control device.

The lifting and roller mechanism includes as shown in FIG. 6 : a support frame 18 , and a front wheel 19 and a rear wheel 20 installed at the bottom of the support frame 18 .

Wherein, Fig. 1 is the hand-pushed wheelchair type state, and Fig. 2 is the bed type state.

Transforming from Figure 1 (hand-push wheelchair position) to Figure 2 (bed position) requires the following four steps:

Step 1. Adjust the upper body lifting mechanism as shown in Figure 3: Adjust the electric push rod 8 through the control button 22, so that the backrest 9 can rotate around the pin shaft 10 to reach the required angle, and then the foldable U-shaped leg 6 can be pulled down to stand upright , the foldable handle 5 is folded inwardly.
