Description

Stand-up and lie-flat wheelchair with turning function

technical field

The utility model relates to a multifunctional electric wheelchair, in particular to an electric wheelchair with the functions of turning over, standing and lying flat.

Background technique

The wheelchair is an important tool used by the physically disabled and the elderly in rehabilitation. It is not only a means of transportation, but also enables them to participate in social activities and physical exercise, meeting the needs of the disabled. For patients who have not recovered the ability to stand and walk independently, it is necessary to give appropriate standing, lying down and turning over to relieve the obstruction of blood circulation caused by sedentary and long-term bed rest, relieve the pressure on the buttocks, and thereby reduce the incidence of bedsores. Wheelchairs currently on the market are varied, including electric wheelchairs with lying and standing functions, but lack electric wheelchairs combined with the function of turning over. For sedentary and bedridden patients, nursing personnel need to regularly turn over and pat their backs to prevent bedsores, which is time-consuming and laborious and has uneven effects. The cushions of most wheelchairs do not tilt inward when they are in a sitting position, which also makes it easy for patients who have been bedridden for a long time to slide down, making it difficult to maintain a sitting position.

Contents of the invention

The utility model is to provide a standing and lying flat wheelchair with the function of turning over, so that the user can freely control lying down, standing and turning over, so that patients with inconvenient movements can pass through the standing position of the wheelchair even if they sit for a long time or lie in bed for a long time. And the function of turning over can relieve the long-term pressure on the buttocks and back, reduce the occurrence of bedsores, and improve the comfort and functionality of the wheelchair.

As shown in Figure 1, the foot support mechanism is respectively connected with the cushion frame 6 and the wheelchair frame 4 in rotation, the cushion frame 6 is placed on the vehicle frame by the roller 5, the seat cushion frame 6 is provided with a stand-up mechanism, and is connected with the left and right backrest frames. 7 and 8 are connected by rotation, the standing mechanism is located under the wheelchair frame, and the driving mechanism, turning mechanism, standing mechanism and flat lying mechanism are respectively connected with the control structure to realize turning, standing, lying flat and universal driving control.

Travel mechanism is made up of cushion frame 6 and wheelchair vehicle frame 4, front universal small wheel 1, rear drive wheel 2 and rear wheel drive motor 3 and form. In order to prevent the uphill and flat lying type wheelchair from toppling backwards, the anti-tilt wheel 26 preventing backward tilting is added. Equally, in order to prevent that the stand 13 is suspended in the air and cause forward tilt when standing, a front anti-tilt wheel 14 is added at the stand 13 bottoms.

 As shown in Figure 3, the lying mechanism includes a back-lifting mechanism and a foot-supporting mechanism. In the back mechanism, the back motor 22 is rotatably connected to the backrest shaft 20 and the back motor fixing frame 25 at H and J respectively, the back motor fixing frame 25 is fixed to the cushion frame 6, and the backrest shaft 20 is rotatably connected to the cushion frame 6. at I. The simplified schematic diagram can be regarded as a triangular connecting rod structure with H, I, and J as vertices. When 22 is running, the rotational connection of each point simultaneously forms a change in the overall structure, achieving the effect of lifting the back. In the leg receiving mechanism, the wheelchair frame 4, the leg support frame 12, the tripod support frame 13, and the connecting rod 15 are connected to the F, B, A, and E positions front and rear, the cushion frame 6 and the leg support frame 12 are connected to the G position, and the leg support frame 12 is connected to the G position. The motor 17 is connected with the wheelchair frame 4 and the leg support 12 respectively at C and D places. When the leg receiving motor 17 moves, the leg support frame 12 slowly lifts up, and the parallelogram structure F, B, A, E makes the leg support frame 13 maintain a level during the ascent process, and the eccentricity of G and F makes the cushion frame 6 in the process of rising. Do this at a slight angle. During the use of the patient, two functions of lying flat-sitting or lying flat-back up can be automatically realized.

As shown in Figure 4, the backrest shaft 20 is an inverted T-shape, the middle is used as the left backrest frame 7, the rotating shaft of the right backrest frame 8, and the bottom is rotationally connected with the cushion frame 6, and when it is lying flat, the backrest shaft 20 is used as the left backrest frame 7, the rotating shaft of right backrest frame 8 and left cushion turn over frame 10, the rotating shaft seat cushion turn over frame fixed shaft 29 of right cushion turn over frame 11 rotates around center of rotation K jointly, and left backrest frame 7 and left cushion turn over frame 10 and right backrest frame 8 and Right seat cushion stand-up frame 11 is mutually rotated and connected respectively (its center of rotation is coaxial with I), so that left backrest frame 7 and left seat cushion stand-up frame 10 and right backrest frame 8 and right seat cushion stand-up frame 11 can be turned up respectively when lying flat, In order to achieve the effect of standing up. As shown in Figure 5, the U-shaped block 23 and the cushion frame 6 are connected at the M place, and the two ends of the U-shaped block 32 are equipped with ball bearings 31 respectively, and the stand-up motor fixing frame 30 is fixed on the cushion frame 6, and the stand-up motor 24 and the stand-up motor The fixing frame 30 and the U-shaped block 23 are fixed on L and N. When turning over motor 24 reciprocating motions, U-shaped block 23 rotates around the M place, makes ball bearing 31 promote the left cushion stand-up stand 10 on the cushion stand 6, the right cushion stand-up stand 11 and the left backrest frame 7 that links to each other, the right backrest Frame 8 rotates around K to realize the function of standing up.

As shown in Figure 6, in order to make the process that the cushion frame 6 that the leg raising action causes becomes horizontal does not affect the stroke of standing motor 18, therefore increases the motor connector 32 of standing, and the motor connector 32 of standing is connected with the cushion frame 6 at O The seat cushion frame 6 is connected to the G place with the leg support frame 12, and the two ends of the standing motor 18 are connected to the P and Q places with the standing motor connector 32 and the wheelchair frame 4 respectively. When the standing motor 18 runs, the standing motor connector 32 promotes the cushion frame 6 to rotate around G, so that the wheelchair can stand up.
