Cushion and cushion frame 6 are respectively connected with leg support 4 and backrest 12 in rotation, and the lower part of seat cushion and cushion frame 6 is provided with a flat lying mechanism capable of lying down. The flat lying mechanism is connected with the respective control mechanism to realize the flat lying posture conversion and universal driving control. the

As shown in Figure 1, traveling mechanism is made up of cushion and cushion frame 6 and arc support frame 31, front universal traveling wheel 22 and rear driving wheel 20. In order to prevent the wheelchair from toppling backwards when going uphill and lying flat, small wheels 21 are added to prevent backward dumping. As shown in Figure 5, the seat cushion, the cushion frame 6 and the leg support are rotatably connected at A, and the backrest 12 is connected at D; the backrest 12 and the rear arm 17 are connected at M by the chuck 32; the connecting rod 30 and the rear arm 17 It is connected at E, and is connected with leg rest 4 at B. According to ergonomics, user comfort is considered, and pillow adjustment cushion 13 and massage structure 14 are installed on backrest 12 . As shown in Figure 6, the leg plate 5 is connected to the leg support 4 at A, and one end of the pneumatic cylinder 3 is connected to H and G, and the other end is connected to the pedal 1 at I; the leg bracket 2 and the pedal 1 are connected to P , be connected to O with leg rest 4, be convenient to medical staff and carry out split-leg care to patient like this. As shown in Figure 7, the handrail 15 is connected to the back guardrail 9 and the backrest 12 at J and D respectively, the guardrail bar 11 is connected to the back guardrail 9 and the backrest 12 at K and L respectively, and the motor frame 19 is welded to the cushion and the cushion frame 6. The motor 18 is placed on the motor frame 19 . This design allows the wheelchair to retract the side rails when in a sitting position and erect the side rails when lying flat, helping to protect the safety of the patient when the posture changes. the

As shown in Figure 4, the present invention has designed a kind of arc-shaped leg frame 31 of wheelchair, and cushion frame 6 and arc-shaped leg frame 31 are welded on Q, and toilet collector 26 is installed in the draw-in groove under seat cushion and seat cushion frame 6. The user can hold the handle and take out the toilet bowl 26 from the side of the wheelchair. Such a design is more convenient for the caregiver to clean the toilet in time. (One of the main protection points of invention rights)

As shown in Figure 5, the seat cushion and the cushion frame 6 and the leg rest are connected at A place in rotation, and the backrest 12 is connected at the D place; the backrest 12 and the rear arm 17 are connected at the M place by the chuck 32; the connecting rod 30 and the rear arm 17 Connected at E, connected with leg rest 4 at B, motor frame 19 welded to seat cushion and cushion frame 6, motor 18 placed on motor frame 19, linear motor 27, motor box 18, backrest 12 respectively connected to F, C place. The simplified schematic diagram can be regarded as a quadrilateral connecting rod structure with vertices A, B, D, E and a linear motor connected to it to achieve the flat lying function of the wheelchair. The connections between the points A, B, C, D, E, and F are all rotational connections. When the linear motor 27 is running, the rotational connections of each point form a change in the overall structure at the same time, allowing the user to achieve a sitting position-lying position. convert. the

As shown in Figure 7, handrail 15 is connected with back guardrail 9 and backrest 12 respectively at J, D place, guardrail bar 11 is connected with back guardrail 9 and backrest 12 respectively at K, L place, linear motor 27 and motor box 18, backrest 12 are respectively connected at F, C places, and motor frame 19 is welded on cushion and cushion frame 6, and motor 18 is placed on the motor frame 19. Simplified into a schematic diagram, it can be regarded as a quadrilateral connecting rod structure with J, K, L, and D as vertices and a linear motor connected to it to achieve the adjustable function of the back guardrail. The connection between each point of J, K, L, C, D, and F is a rotational connection. When the linear motor 27 is running, the rotational connection of each point forms a change in the overall structure at the same time, so that the wheelchair can achieve the adjustable function of the back guardrail. the

The control mechanism is a controller 8 for driving the wheelchair. What the universal controller of drive travel adopts is the control mechanism of common electric wheelchair, directly drives rear driving wheel 20 with driving rear wheel motor 21, makes patient no matter when sitting or lying down, can move freely independently. The posture conversion button of lying flat-standing posture conversion is located at the controller 8, and by driving the linear motor 27, the patient is allowed to perform any conversion from sitting posture to sitting posture, so that the user can recover exercise and take care of himself in daily life independently, and carry out restorative training to the legs It is used to effectively alleviate the nursing burden of the disabled, their families, and medical care. the

Function and effect of the embodiment

To sum up, the electric wheelchair with the function of nursing bed in this embodiment can enable the user to freely switch between the sitting posture and the lying state on the wheelchair, effectively increasing the user's self-care ability and improving the user's mental health. Under the action of the guardrail, the user's safety is further guaranteed. And the design of the locker of the urinal greatly facilitates the care of the nursing staff. More to achieve the effect of self-interest and others. the
