[0029] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0030] The following disclosure provides many different implementation methods or examples for different ways of implementing this utility model.
[0031] Reference Figures 1 to 6As shown, a wheelchair for use with a bed includes a frame 1, a seat frame 2, a back support 3, a leg support 4, and a first direction. The frame 1 is equipped with wheels 5 and a lifting device 6. The lifting device 6 is connected to the seat frame 2 to drive the seat frame 2 to rise and fall. The back support 3 and the leg support 4 are respectively connected to both ends of the seat frame 2 along the first direction. The seat frame 2 is hinged with guard plates 7 on both sides along the first direction. The seat frame 2 is equipped with a first electric push rod 21 that corresponds one-to-one with the guard plate 7. One end of the first electric push rod 21 is hinged to the seat frame 2, and the other end of the first electric push rod 21 is hinged to the guard plate 7.
[0032] The guard plate 7 is rotatable. Relying on the first electric push rod 21, the guard plate 7 can be rotated to a vertical or flat position. When the guard plate 7 is in a vertical position, the two guard plates 7 protect the rider on both sides, providing protection. When the guard plate 7 is in a flat position, the seat cushion frame 2 and the guard plate 7 can be adjusted to a height that matches the bed position under the action of the lifting device 6. At this time, the rider can easily move from the seat cushion frame 2 to the bed position.
[0033] In this embodiment, the back support 3 is hinged to the seat cushion frame 2. The seat cushion frame 2 is provided with a second electric push rod 22. One end of the second electric push rod 22 is hinged to the seat cushion frame 2, and the other end of the second electric push rod 22 is hinged to the back support 3.
[0034] The second electric push rod 22 can adjust the angle between the back support 3 and the seat cushion 2, allowing the back support 3 to lie flat when necessary, making it convenient for the passenger to lie down.
[0035] In this embodiment, the leg support frame 4 is hinged to the seat cushion frame 2. The seat cushion frame 2 is provided with a third electric push rod 23. One end of the third electric push rod 23 is hinged to the seat cushion frame 2, and the other end of the third electric push rod 23 is hinged to the leg support frame 4.
[0036] The third electric push rod 23 can adjust the angle between the leg support 4 and the seat cushion 2. When necessary, the leg support 4 can be laid flat, thus facilitating the passenger to lie down.
[0037] In this embodiment, cushions can be placed on the seat frame 2, back support 3, and leg support 4 to improve the comfort of the rider.
[0038] In this embodiment, the leg support frame 4 includes a first frame 41 and a second frame 42 arranged in parallel, both of which are hinged to the seat cushion frame 2.
[0039] It also includes a footrest 8 located at the end of the leg support 4 away from the seat cushion frame 2. The first frame 41 and the second frame 42 are both hinged to the footrest 8. The seat cushion frame 2, the first frame 41, the second frame 42 and the footrest 8 form a parallelogram linkage mechanism, so that the posture of the footrest 8 can always be maintained. No matter how the leg support 4 changes its angle, the posture of the footrest 8 will not change, only the height will be adjusted, so as to always support the feet of the passenger.
[0040] In this embodiment, a tabletop 9 is also included. Two grooves are arranged at intervals on the tabletop 9. When the guard plate 7 is in a vertical position, the two grooves of the tabletop 9 are respectively fitted onto the two guard plates 7, so that the tabletop 9 is mounted above the seat cushion frame 2. At the same time, it can also restrict the two guard plates 7 and prevent the guard plates 7 from rotating. When not needed, the tabletop 9 can be removed at any time.
[0041] In this embodiment, the lifting device 6 is a lifting column, and the output end of the lifting column is connected to the seat cushion frame 2; the lifting column drives the seat cushion frame 2 to move up and down.
[0042] The seat cushion 2 and the frame 1 form a storage space, and the storage space is equipped with a power supply 10, which is responsible for providing power to various drive components on the wheelchair. The power supply 10 and the frame 1 are detachably connected, which is convenient for disassembly and replacement. Of course, it is also feasible to set it to be rechargeable.
[0043] In this embodiment, there are two power supplies 10 located on both sides of the lifting column along the first direction, which facilitates the retrieval and placement of the power supplies 10.
[0044] Preferably, a protective panel 11 is provided on the side of the power supply 10 away from the lifting column. The protective panel 11 is connected to the frame 1 and serves to protect the power supply 10 from being hit.
[0045] In this embodiment, the wheel 5 includes a drive wheel 51 and an auxiliary wheel 52. There are two drive wheels 51 and they are located at one end of the frame 1 near the back support 3. The frame 1 is provided with a drive motor 53 for driving the corresponding drive wheel 51 to rotate. There are two auxiliary wheels 52 and they are located at one end of the frame 1 near the leg support 4.
[0046] Meanwhile, a protective cover 12 is provided above the drive wheel 51. The protective cover 12 is connected to the frame 1. The protective cover 12 is provided with a through groove for the second electric push rod 22 to move. The protective cover 12 can protect the drive wheel 51 and the drive motor 53 and prevent them from being damaged.
[0047] In this embodiment, a remote control can be installed on the backrest 7 to facilitate the control of the angles of the back support 3, the leg support 4, the backrest 7, and the seat cushion 2. A neck support can also be installed on the backrest 3.
[0048] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
