[0030] With economic development and improved living standards, human lifespan is gradually increasing, and the aging population is becoming increasingly severe. Simultaneously, the number of people with disabilities is also increasing year by year, primarily due to traffic accidents and genetic diseases. People with disabilities differ from the elderly in their daily lives. They are not only affected in their work but also struggle with basic daily activities. The age of onset for people with disabilities is trending younger, with teenagers and middle-aged individuals being the main groups affected. Caring for people with disabilities places a huge economic burden on their families. Furthermore, the physical barriers they face in daily life also cause them significant psychological stress. In addition, some people lose varying degrees of self-care ability due to physical illnesses such as brain diseases, strokes, and spinal cord injuries. Transferring disabled or semi-disabled elderly and people with disabilities from wheelchairs to beds or vice versa is a challenging issue, especially for those who are heavier.

[0031] As described in the background section, currently, transferring disabled or semi-disabled elderly people and people with disabilities from wheelchairs to beds or from beds to wheelchairs is achieved through transfer devices. These transfer devices are space-consuming and inconvenient to carry, resulting in low wheelchair utilization. To address this problem, this application provides a wheelchair with a transfer commode function, which effectively solves the difficulty for disabled or semi-disabled elderly people and people with disabilities in transferring from wheelchairs to beds or from beds to wheelchairs, thereby improving their quality of life.

[0032] This application provides a wheelchair with a movable commode function. The wheelchair has a front-to-back direction and a width direction, with the two ends in the front-to-back direction being a front end and a rear end. The wheelchair includes:

[0033] The pulley base 1 is provided with a lower middle plate 11, and the front end of the lower middle plate 11 is provided with a hollow hole;

[0034] The slide rail device 2 is disposed on the lower middle plate 11. The slide rail device 2 is arranged along the width direction of the lower middle plate 11 and is located on both sides of the hollow hole.

[0035] The seat structure 3 includes an upper middle plate 31, a first angle adjuster 32, a foot pedal 33, a second angle adjuster 34, and a backrest 35. The upper middle plate 31 is slidably mounted on the slide rail device 2. The upper middle plate 31 has a cover plate 17 corresponding to the position of the hollow hole. The foot pedal 33 is hinged to the front end of the upper middle plate 31 through the first angle adjuster 32. The backrest 35 is hinged to the rear end of the upper middle plate 31 through the second angle adjuster 34.

[0036] The seat structure 3 is capable of sliding a first distance relative to the pulley chassis 1 along the slide rail device 2 in the width direction, and the foot pedal 33, the upper middle plate 31 and the backrest 35 are adjustable in a plane.

[0037] In this embodiment, the components of the seat structure 3 in the wheelchair can be flattened out on a plane, which makes it convenient for the human body to rest in a lying position on the seat structure 3.

[0038] The wheelchair in this embodiment not only performs the functions of a conventional wheelchair, but also, by flattening the seat structure 3 into a plane, it facilitates the transfer of disabled or semi-disabled elderly people and people with disabilities from the wheelchair to the bed or vice versa. By setting a sliding rail device 2 between the pulley chassis 1 and the seat structure 3, the seat structure 3 can slide a first distance relative to the pulley chassis 1, which facilitates the transfer of the human body between the wheelchair and the bed. Moreover, during use, after sliding a first distance toward the bed, the components of the seat structure 3 can be flattened into a plane, and the seat structure 3 is completely flush with the bed, facilitating the transfer of the human body. There is no need to use a transfer device to assist in the transfer of the human body between the wheelchair and the bed. The wheelchair is convenient to use, improves the user experience, and increases the utilization rate of the wheelchair.

[0039] The wheelchair in this embodiment can also solve the problem of toileting difficulties for disabled elderly people. The wheelchair in this embodiment has a perforated hole at the front end of the lower middle plate 11, and a cover plate 17 corresponding to the perforated hole on the upper middle plate 31. To use the toilet, the cover plate 17 can be opened. A bucket structure can be installed corresponding to the perforated hole to realize the toilet function. This effectively solves the problem of toileting difficulties for disabled, semi-disabled, and disabled elderly people and improves their quality of life.

The first protective plate 36 and the second protective plate 37 are respectively hinged to both sides of the upper middle plate 31 in the width direction. The first protective plate 36, the upper middle plate 31 and the second protective plate 37 can be adjusted to be in a plane.

[0041] Understandably, when transferring disabled or semi-disabled elderly people and people with disabilities from wheelchairs to beds or from beds to wheelchairs, the planes containing the first protective plate 36, the upper middle plate 31, and the second protective plate 37 are the same plane as the planes containing the footrest 33, the upper middle plate 31, and the backrest 35, which are flush with the bed.

[0042] In this embodiment, the seat structure 3 further includes a first hinge mechanism 361, a first pin structure 362, a second hinge mechanism 371, and a second pin structure 372. The bottom of the first protective plate 36 is hinged to the first side of the upper middle plate 31 in the width direction through the first hinge mechanism 361. The first pin structure 362 is located at the front end of the first protective plate 36 and is fixed by the first pin structure 362 when the first protective plate 36 is perpendicular to the upper middle plate 31. The bottom of the second protective plate 37 is hinged to the second side of the upper middle plate 31 in the width direction through the second hinge mechanism 371. The second pin structure 372 is located at the front end of the second protective plate 37 and is fixed by the second pin structure 372 when the second protective plate 37 is perpendicular to the upper middle plate 31. The first pin structure 362 and the second pin structure 372 are used to fix the first protective plate 36 and the second protective plate 37, keep the first protective plate 36 and the second protective plate 37 and the upper plate 31 in a vertical state, and can also unlock the first protective plate 36 and the second protective plate 37, so that the first protective plate 36, the upper plate 31 and the second protective plate 37 can be adjusted to be in the same plane.

[0044] When the wheelchair is in normal use, adjust the first angle adjuster 32 and the second angle adjuster 34 to 90°, so that the backrest 35 and footrest 33 are in a vertical position. Adjust the first protective plate 36 and the second protective plate 37 to 90° using the hinge mechanism, and make the casters 13 and drive wheels 14 contact the ground. Have the person sit on the upper middle plate 31 and the lower middle plate 11, place their feet on the footrest 33, and lean their back against the backrest 35.

[0045] When it is necessary to transfer a person from a wheelchair to a bed, the first angle adjuster 32 and the second angle adjuster 34 are adjusted to 180°, so that the backrest 35 and footrest 33 are in a horizontal position and the pulley base 1 is in contact with the ground. At this time, the scissor lifting mechanism 16 is raised to the height of the bed surface by the hydraulic device 15, and the wheelchair is brought close to the bed. The first protective plate 36 and the second protective plate 37 are fixed to 180° by the first hinge mechanism 361 and the second hinge mechanism 371, respectively. The upper plate 31 is slid to the bed surface using the slide rail device 2 on the lower plate 11, and then the person is manually pushed onto the bed. This wheelchair can effectively solve the problem of the difficulty of transferring disabled and semi-disabled elderly people and people with disabilities from wheelchairs to beds or from beds to wheelchairs, and improve the quality of life of disabled and semi-disabled elderly people and people with disabilities.

[0046] In this embodiment, the wheelchair with the movable commode function further includes:

[0047] The bedpan 4 is fitted into the hollow hole of the lower plate 11.

[0048] Preferably, the perforation is rectangular, and the opening edge of the bedpan 4 can be supported within the perforation for easy placement and removal of the bedpan 4. The cover plate 17 has the same shape as the perforation, being rectangular, which facilitates use by people in wheelchairs or when entering the restroom.
