1 to 7 , the electric wheelchair according to an embodiment of the present invention includes a seat 110 and an elevating unit 120 .

The seat 110 is for the user of the electric wheelchair to be seated. can

Here, the seat 110 may further include a footrest part 113 that is rotatably coupled to the front end of the seating part 111 to support the user's leg. At this time, the upper end of the footrest part 113 may be hinged to the front end of the seating part 111 , and rotated from an angle perpendicular to the seating part 111 to an angle horizontal by a motor (not shown). can be For example, as shown in FIG. 2 , the footrest unit 113 may rotate to be horizontal with the seating unit 111 .

On the other hand, when the guardian moves the user to the bed, the backrest part 112 and the footrest part 113 may rotate to form the same plane as the seating part 111 . That is, when the guardian moves the user to the bed, the seating unit 111, the backrest unit 112, and the footrest unit 113 may rotate so that the user is in a lying state so as to be horizontal.

The elevating unit 120 is provided at the four lower corners of the seating unit 111 to elevate the seat 110, and is provided at each of the lower four corners of the seating unit 111 to elevate and descend to different heights. 110) can be tilted.

Specifically, the elevating unit 120 may be a cylinder, and the front left side of the seating unit 111 , the front right side of the seating unit 111 , the rear left side of the seating unit 111 , and the rear right side of the seating unit 111 . It is provided in each of the elevating and lowering, respectively, it is possible to tilt the seat (110).

For example, as shown in FIG. 3 , when all four elevating units 120 rise, the seat 110 is elevated.

In addition, as shown in FIG. 4 , when the elevating unit 120 on the left and right sides of the seat 110 is lowered, the seat 110 is tilted forward when the elevating unit 120 at the rear left and right sides of the seat 110 rises. . At this time, when the backrest 112 and the footrest 113 are rotated to form a plane with the seat 110 and tilted forward, it can serve as a standing bed, which is one of the important rehabilitation treatments for paralyzed patients.

And as shown in FIG. 5, when the elevating unit 120 of the front right and rear right of the seat 110 descends, and the elevating unit 120 of the front left and rear left of the seat 110 rises, the seat 110 is will be tilted to the right. In addition, as shown in FIG. 6 , the elevating unit 120 of the front left and rear left of the seat 110 rises, and when the elevating unit 120 of the front right and rear right of the seat 110 descends, the seat 110 is will be tilted to the left. In addition, as shown in FIG. 7 , when the elevating unit 120 on the left and right sides of the seat 110 is raised, the seat 110 is tilted backward when the elevating unit 120 on the left and right sides of the seat 110 is lowered. do.

Accordingly, the user's posture can be changed by tilting the seat 110 through the elevating and lowering of the elevating unit 120 as described above. By tilting to the left or right through the elevation of the elevation part 120 after making the 112 and the footrest part 113 horizontal, it is possible to reverse the center of gravity of the body leaning to the left and right side, so that you can sit in a wheelchair for a long time. It is possible to prevent pressure sores by allowing the user to rest while removing the pressure in the area where pressure sores are common. In addition, by tilting backward through the elevation of the elevation unit 120, it is possible to prevent the occurrence of edema by allowing the paralyzed patient to have a posture to raise the leg for the paralyzed patient, who is always sitting so that blood circulation does not occur and edema occurs in the leg. can do.

A process in which a user moves to a bed using an electric wheelchair according to an embodiment of the present invention configured as described above will be described as follows.

First, as shown in FIG. 9, the electric wheelchair is placed side by side on the side of the bed and the seating part 111, the backrest part 112 and the footrest part 113 are driven so that the user is in a lying state so as to be horizontal. .

And, as shown in Figure 10, the seat 110, the front left and rear left of the elevating unit 120 is raised, the seat 110, the front right and rear right of the elevating unit 120 is lowered to the seat 110 tilt to the left. At this time, the rolling board 10 is inserted under the user's body (the back, the seat surface and the leg part) and arranged to span between the electric wheelchair and the bed.

Next, as shown in FIG. 11, the elevating unit 120 of the front left and rear left of the seat 110 is lowered by the height of the bed, and the elevating unit 120 of the front right and rear right of the seat 110 is By tilting the seat 110 to the left by rising higher than the bed, the user's center of gravity is shifted toward the bed through the rolling board, and the user is moved to the bed.

Conversely, when the user moves from the bed to the electric wheelchair, the electric wheelchair is positioned side by side on the side of the bed, and the seating portion 111, the backrest portion 112, and the footrest portion 113 are driven to be horizontal. Thereafter, the rolling board 10 is inserted under the user's body (the back, the seat surface, and the leg part) and arranged to span between the electric wheelchair and the bed. Thereafter, the elevating unit 120 of the front left and rear left of the seat 110 is raised by the height of the bed, and the elevating unit 120 of the front right and rear right of the seat 110 is lowered than the bed to lower the seat 110 By tilting to the right, the user's center of gravity is shifted toward the electric wheelchair through the rolling board, allowing the user to naturally move to the wheelchair.

So far, with respect to the present invention, the preferred embodiments have been looked at. All embodiments and conditional examples disclosed throughout this specification have been described with the intention of helping those skilled in the art to understand the principles and concepts of the present invention, those skilled in the art. It will be understood that the present invention may be implemented in a modified form without departing from the essential characteristics of the present invention.
