[0030] See also Figure 1-6The utility model provides a technical solution: a wheelchair for the disabled with an auxiliary standing structure, including a base 1, a seat cushion 2, a backrest 3, rear wheels 4, front wheels 5, a support column 6, an armrest 7, a connecting rod 8, an electric push rod 9, a connecting block 10, a supporting foot pad 11, a connecting pad 12, a connecting plate 13, and an eccentric wheel 14.

[0031] The base 1 is a plate-shaped structure, a seat cushion 2 is fixedly mounted on the upper surface of the base 1, a backrest 3 is fixedly mounted on the upper surface of the base 1, a certain angle is set between the backrest 3 and the seat cushion 2, a rear wheel 4 is arranged below the base 1, two rear wheels 4 are symmetrically arranged, the two rear wheels 4 are connected to the same shaft surface, the shaft of the rear wheel 4 is rotatably connected to the lower surface of the base 1 through a bracket, a front wheel 5 is arranged below the base 1, two front wheels 5 are symmetrically arranged, the two front wheels 5 are connected to the same shaft surface, the shaft of the front wheel 5 is rotatably connected to the lower surface of the base 1 through a bracket Next, an armrest adjustment structure is provided on the upper surface of the base 1, and a sliding armrest 7 is provided on the armrest adjustment structure to assist the disabled to stand up. The armrest adjustment structure includes a support column 6, and the support column 6 is fixedly installed on the upper surface of the base 1. Two support columns 6 are respectively arranged on both sides of the cushion 2. The outer surfaces of the two support columns 6 are slidably provided with armrests 7, and the outer surfaces of the armrests 7 are provided with flexible materials. The lower surfaces of the two armrests 7 are connected to the surface of the same connecting rod 8, and an electric push rod 9 is fixedly installed on the upper surface of the connecting rod 8, and the output end of the electric push rod 9 is connected to the surface of the connecting rod 8;

[0032] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, when using the device, the disabled person sits on the upper surface of the seat cushion 2 and contacts the backrest 3 with the backrest 3. At this time, the accompanying person can hold the handle on the surface of the backrest 3 to push the device to move. The device moves under the drive of the rear wheel 4 and the front wheel 5. If the height of the armrest 7 is not suitable for the disabled, the electric push rod 9 is started, and the electric push rod 9 drives the connecting rod 8 to move upward. The connecting rod 8 drives the armrests 7 on both sides to slide upward on the outer surface of the support column 6, so as to adjust the height of the armrest 7 to adapt to different disabled people. When the disabled person needs to get up, the electric push rod 9 is also started. During the process of the electric push rod 9 driving the armrest 7 to move upward, the upward thrust will give the disabled person's arm an upward supporting force, so that the disabled person can get external support in the process of getting up, thereby assisting the disabled person to get up.

[0033] A leg movable structure is provided below the base 1. A rotating connecting plate 13 is provided on the leg movable structure to realize pressing movement on the disabled person's legs during the movement of the device. The leg movable structure includes a connecting block 10. The connecting block 10 is fixedly installed on the surface of the base 1 through a bracket. A supporting foot pad 11 is rotatably connected between the two bases 1. A connecting pad 12 is provided on the surface of the supporting foot pad 11. The other end of the connecting pad 12 is fixed to the surface of the base 1. The connecting pad 12 is made of a stretchable flexible material. A connecting plate 13 is rotatably connected to the lower surface of the base 1. The connecting plate 13 is located on one side of the connecting pad 12, and a plurality of hammers are equidistantly provided on the surface of the connecting plate 13. The hammers on the surface of the connecting plate 13 are in contact with the surface of the connecting pad 12. Two eccentric wheels 14 are provided on the outer surface of the rotating shaft of the front wheel 5. The diameter of the eccentric wheel 14 is smaller than that of the front wheel 5, and the eccentric wheel 14 is in contact with the surface of the connecting plate 13.

[0034] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, when a disabled person sits on the surface of the device, he places his feet on the surface of the supporting foot pad 11. At this time, the disabled person's calf part contacts the flexible connecting pad 12. When the device is pushed to move, the rotating shaft of the front wheel 5 rotates, thereby driving the eccentric wheel 14 to rotate. The rotating eccentric wheel 14 pushes the connecting plate 13 to one side, so that the connecting plate 13 rotates on the lower surface of the base 1. The rotating connecting plate 13 drives the hammer on the surface to strike the surface of the connecting pad 12, thereby achieving the knocking of the leg muscles on the surface of the connecting pad 12, thereby achieving the synchronous activity of the leg muscles during the movement of the device.

[0035] Working principle: When using the wheelchair with an auxiliary standing structure, the disabled person places his feet on the surface of the supporting foot pad 11 and contacts the calf with the connecting pad 12 to push the device to move. At this time, the front wheel 5 rotates, and the rotating front wheel 5 drives the eccentric wheel 14 to rotate synchronously. The rotating eccentric wheel 14 continuously drives the connecting plate 13 to rotate, and the rotating connecting plate 13 drives the hammer on the surface to strike the surface of the connecting pad 12, thereby striking the leg muscles on the surface of the connecting pad 12. When it is necessary to stand up, start the electric push rod 9, which drives the connecting rods 8 on both sides to move upward, and the connecting rod 8 drives the armrest 7 to slide upward, thereby giving the disabled person an external thrust to assist the disabled person to stand up and increase the overall practicality.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
