a plurality of wheels mounted to the chassis and provided with a brake device;

In this way, the lifting device is mounted to the chassis through a specially designed bracket, and a seat (for example, a seat) mounted to the top of the lifting device can be lifted and lowered along with the lifting and lowering movement of the top of the lifting device, so that the height of the seat from the ground can be adjusted within a certain range as required, for example, corresponding to (especially flush with) the height of a household facility (for example, a toilet or a bed), thereby facilitating the user to adjust the state to realize the transfer between the household facility and the walking transfer device with lifting function (which may be simply referred to as a walking transfer device, such as a wheelchair). Therefore, the self-care ability of the old user can be improved to a certain degree, the burden of nursing staff can be reduced, the action difficulty and risk are reduced, and the safety of the walking transfer device is improved.

It should be noted that in order to enable the seat to be lowered to a sufficient height above the ground to meet specific needs, the lifting device needs to be mounted to a position as low as possible, here to the mounting plane of the bracket (i.e., the upper surface of the connecting portion), the bracket being specially designed to have an upwardly open U-shape to provide a space therein to house the lifting device so that the lifting device is spatially located below the upper cross member (i.e., the first and second cross members) of the chassis, not only allowing the lifting device to be mounted in a low position to allow the seat to have a lower adjustable height, but also allowing the entire walking transfer device to be lowered in center of gravity to be more stable and compact.

In addition, the lifting device is firmly connected with the chassis through the bracket, so that all the components are connected into a whole, and the walking transfer device has higher overall structural strength and stability.

Furthermore, the braking means provided on the wheels enable a more stable travel transfer device when parking, making the transfer between the travel transfer device (e.g. a wheelchair) and the household facility (e.g. a toilet or a bed) safer and more reliable.

Therefore, the walking transfer device with the lifting function provided by the embodiments of the present invention can assist the user to adjust the state, so as to facilitate the transfer between the walking transfer device (such as a wheelchair) and the household facility (such as a toilet or a bed).

It should be noted that unless expressly stated or limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly and include, for example, fixed or removable connections or integral connections; the connection can be mechanical connection or electrical connection; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements.

In one embodiment, optionally, the pedal is rotatably mounted. Therefore, the utility model can be folded in time when not in use; in addition, when the backrest is extended rearwardly for the user to lie down as previously described, the pedals can be rotated to the appropriate angle to provide foot and leg support for the user.

In one embodiment, optionally, the backrest is foldable or elastically deformable to shorten the lateral width (i.e., the width in the left-right direction). Thus, the wheelchair can be folded and folded when not in use.

In one embodiment, optionally, the backrest is foldable or elastically deformable along a vertical axis.

In one embodiment, optionally, the backrest comprises a locking mechanism for locking the backrest in position. In this way, the backrest, when locked in place, does not move (e.g., rotate) even when subjected to external forces, thereby improving safety.

In one embodiment, optionally, a waist belt is provided on the backrest. In this way, if desired, the user can be tightened against the backrest by means of a waist belt to prevent accidental slipping.

In one embodiment, optionally, the seat is removably mounted to the top of the lifting device. In this way, inspection, maintenance and repair of the lifting device can be facilitated.

In one embodiment, optionally, a cushioning structure is provided between the seat and the top of the riser. Thus, the external force can be buffered, and a comfortable riding environment can be provided for the user.

In one embodiment, optionally, the cushioning structure comprises a spring.

Preferably, in any embodiment, the two wheels respectively located at both sides of the chassis are driving wheels respectively driven by two motors independent of each other.

In one embodiment, optionally, the two drive wheels are two drive front wheels driven independently of each other. Thus, for example, one drives the front wheel to rotate forwards, and the other drives the front wheel to rotate backwards, so that the steering can be conveniently and flexibly realized, and the movement in a narrow space is convenient.

In one embodiment, optionally, the two drive wheels are two driven rear wheels driven independently of each other. Thus, for example, one drives the rear wheel to rotate forwards, and the other drives the rear wheel to rotate backwards, so that the steering can be conveniently and flexibly realized, and the movement in a narrow space is convenient.
