The technical scheme is as follows: the wheelchair comprises a wheelchair main body, wherein a driving assembly is arranged at the top of a backrest of the wheelchair, and a motor is arranged in the driving assembly; the seat of the wheelchair main body is paved with the cloth, one end of the cloth is fixed at the front end of the seat, and the other end of the cloth is tightly sleeved on a rotating shaft of a motor in the driving assembly; the tilting mechanism is arranged below the seat of the wheelchair main body, the cloth is attached to the seat in a normal state, the motor in the driving assembly starts to rotate in the process that the tilting mechanism tilts the seat by a preset angle, and one end of the cloth is continuously rolled up by a motor rotating shaft until the cloth is straightened.
The drive assembly comprises two motor shells which are arranged at intervals, the motor shells are connected into a whole through a connecting rod, motors are arranged in the two motor shells, the two motors share a rotating shaft, and the rotating shaft is located in front of the connecting rod.
The driving assembly is installed on the wheelchair main body through bolts, and installation is simple.
The horizontal pole is worn to establish by cloth collapsing one end, and the horizontal pole both ends are stretched out cloth collapsing and are fixed in the seat both sides through the bolt, avoid collapsing cloth and drop suddenly at the in-process of flare-outing, cause the injury for the patient.
The width of the cloth is larger than that of the headrest of the main body of the wheelchair, and meanwhile, the width of the cloth is smaller than that of the seat of the main body of the wheelchair, so that the problem that the cloth is too wide and cannot be installed is prevented, and discomfort can be brought to the human body when the cloth is too narrow and straightened.
The cloth is formed by sticking a plurality of small pieces, and is convenient to disassemble, assemble and clean.
And a lifting mechanism is arranged below the tilting mechanism, and when the lifting mechanism lifts the seat upwards, the tilting mechanism tilts the seat to assist in standing.
The wheelchair comprises a wheelchair body and is characterized by further comprising a left handrail component and a right handrail component which are arranged on two sides of the wheelchair body, wherein a controller is arranged on the right handrail component, and the controller controls the driving assembly and the tilting mechanism to act so as to realize one-key control.
Still including setting up the fixed leg support subassembly in the pedal top of wheelchair car main part, when the human body stands, prevent to fall from the wheelchair and fall and hinder.
Has the advantages that: compared with the prior art, the invention has the beneficial effects that: (1) one-key station assistance is realized through simple operation, so that the use by a user is facilitated; (2) accessories of the station-assisting function, such as a driving assembly and cloth collapsing, meet the modular design, are simple and convenient to install and convenient to carry; (3) the standing assisting function does not influence the normal use of all the original functions of the wheelchair, such as rotation, leisure and the like, and does not influence the performance of the wheelchair for passing through the ditch and the ridge and the like; (4) when the station is helped, the walking aid can cross the ridge of 2.5cm to help the walking aid to walk in a room with fall.

FIG. 1 is a schematic structural diagram of a stand-assist mechanism of a wheelchair according to the present invention when the stand-assist mechanism is activated;
fig. 2 is a schematic structural view of the wheelchair standing assisting mechanism in an initial state.
Detailed Description
The invention is described in further detail below with reference to specific embodiments and the attached drawings.
As shown in fig. 1 and 2, the wheelchair comprises a wheelchair main body, and a driving assembly 1, a tipping cloth 2, a left armrest assembly 3, a right armrest assembly 4, a fixed leg rest assembly 5, a tilting mechanism 6 and a lifting mechanism 7 which are arranged on the wheelchair main body. Drive assembly 1 sets up at the back top of wheelchair main part, and drive assembly 1 includes the motor casing that two intervals set up, connects into a whole through the connecting rod between the motor casing, all is equipped with the motor in two motor casings, and two motor sharing pivots, and the pivot is located connecting rod the place ahead. In this embodiment, drive assembly 1 passes through the bolt and installs in the wheelchair car main part, easy dismounting, and comparatively firm. The tipping cloth 2 is laid on a seat of the wheelchair main body and can be formed by sticking a plurality of small pieces, so that the replacement is convenient; in a normal state, the cloth 2 is attached to the seat and is bent approximately 90 degrees integrally, the width of the cloth 2 is larger than that of the headrest of the main body of the wheelchair, meanwhile, the width of the cloth 2 is smaller than that of the seat of the main body of the wheelchair, so that the phenomenon that the cloth cannot be installed due to too wide cloth and discomfort can be brought to the human body due to too narrow cloth when the cloth is straightened is avoided. One end of the cloth 2 is fixed at the front end of the seat, and the other end of the cloth 2 is tightly sleeved on a rotating shaft of a motor in the driving assembly 1; in this embodiment, 2 one ends of cloth are broken and the horizontal pole is worn to establish, and the horizontal pole both ends are stretched out and are broken cloth 2 and pass through the bolt fastening in seat both sides.
The left handrail component 3 and the right handrail component 4 are arranged on two sides of the main body of the wheelchair, the controller is arranged on the right handrail component 4, and the controller controls the driving assembly 1, the tilting mechanism 6 and the lifting mechanism 7 to act. The fixed leg rest assembly 5 is arranged above the pedals of the wheelchair main body, and the fixed leg rest assembly 5 can use bandages or safety belts. The tilting mechanism 6 is arranged below a seat of the wheelchair main body, the tilting mechanism 6 can use two lifting cylinders with different heights, the two lifting cylinders with different heights are arranged in parallel, the cylinder with low height is arranged close to the front of the seat, the cylinder with high height is arranged close to the rear of the seat, the tilting effect can be realized when the two cylinders rise simultaneously, and the tilting mechanism 6 can also be arranged in other modes. And a lifting mechanism 7 is arranged below the tilting mechanism 6.
Before starting the station-assisting function, a user sits on a seat, adjusts the fixed leg support assembly 5, ties the safety belt on the fixed leg support assembly 5 on the leg, fixes the body trunk by the safety belt on the body of the wheelchair, and then presses down the controller on the right armrest assembly 4 to start the station-assisting function; the lifting mechanism 7 lifts the seat upwards to a preset position, and the tilting mechanism 6 tilts the seat to a certain angle; when the tilting mechanism 6 works, a motor in the driving assembly 1 is driven to rotate, one end of the cloth 2 is continuously rolled up by a motor rotating shaft until the cloth 2 is completely straightened, three actions are simultaneously completed, and finally the wheelchair helps a user to realize a station-assisting function.
