For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0028] The present application is further described in detail below through drawings and examples.

[0029] Reference Figures 1 to 4The embodiment of the present application provides a multifunctional wheelchair and flat car dual-purpose device, including a bracket 1, a seat 5 is arranged on the top of the bracket 1, a seat back 4 is hinged on the top of the seat 5, an armrest 6 is fixedly installed on the side of the seat 5, a handle 7 is fixedly installed on the back of the bracket 1, a rear wheel 8 and a front wheel 9 are fixedly installed on the side of the bracket 1, a leg support assembly 2 is arranged on the front of the bracket 1, a back support assembly 3 is arranged between the back of the seat back 4 and the bottom of the bracket 1, and the leg support assembly 2 includes a fixing frame 21, the fixing frame 21 is fixedly installed on the front of the bracket 1, a leg support rod 22 is fixedly installed inside the fixing frame 21 by a first bolt 25, a leg drag 24 is fixedly installed between the two leg support rods 22, and a foot rest 23 is fixedly installed on the inner side of the bottom of the two leg support rods 22 by a first bolt 25.

[0030] In an optional embodiment: the armrests 6 are located on the left and right sides of the seat 5, the front wheels 9 are fixedly mounted on the left sides of the bottom of the bracket 1, and the rear wheels 8 are located on the left and right sides of the bracket 1 and behind the front wheels 9.

[0031] It should be noted that when the device is in use, the patient is supported by the seat 5, the patient's back is supported by the backrest 4, and the free movement of the entire device is achieved by the front wheels 9 and the rear wheels 8.

[0032] In an optional embodiment, the inclination angle of the leg support 24 is the same as the inclination angle of the leg support rod 22, and the foot support 23 is parallel to the ground.

[0033] It should be noted that when the patient sits on the wheelchair, the feet are placed on the footrest 23 and the legs are placed on the leg rest 24. The footrest 23 and the leg rest 24 support the patient's feet and legs. The looseness of the leg support rod 22 and the footrest 23 can be changed by changing the tightness of the first bolt 25, so that the angle of the leg support rod 22 and the angle of the footrest 23 can be adjusted. After adjustment, they are fixed again by the first bolt 25. The adjustable leg support rod 22 and the footrest 23 make the wheelchair more comfortable and applicable when in use.

[0034] In an optional embodiment: the chair back 4 is hinged to the back of the seat 5 , and the handle 7 is fixedly mounted on the back of the bracket 1 and is located on the left and right sides of the chair back 4 .

[0035] It should be noted that the chair back 4 can be laid flat by hingedly connected to the seat 5. When the chair back 4 is laid flat, the rear of the seat 5 and the bottom of the chair back 4 are in contact with each other, which can limit the adjustment angle of the chair back 4 and prevent the chair back 4 from rotating downward too far.

[0036] In an optional embodiment: the back support assembly 3 includes a connecting block 32, the connecting block 32 is fixedly installed above the back of the chair back 4, a back support rod 31 is fixedly installed inside the connecting block 32 through a second bolt 33, a wheel frame 34 is fixedly installed at the bottom of the back support rod 31, and an auxiliary wheel 35 is rotatably connected to the inner side of the wheel frame 34.

[0039] It should be noted that by buckling the hook 38 on the outside of the connecting rod 36, the connecting rod 36 can be pulled by the hanging rod 37. By pulling the connecting rod 36, the chair back 4 can be fixed by the back support rod 31. The chair back 4 can be released by removing the hook 38 from the connecting rod 36.

[0040] Working principle: When the patient needs to lie flat, the hook 38 is removed from the connecting rod 36 to release the fixation of the chair back 4. The chair back 4 is rotated to be parallel to the seat 5, and then the angle of the back support rod 31 is changed to make the back support rod 31 perpendicular to the chair back 4. After the back support rod 31 is adjusted, the auxiliary wheel 35 just touches the ground, so that the chair back 4 is supported by the auxiliary wheel 35 and the back support rod 31, so that the chair back 4 is unfolded to form a movable bed, which solves the problem that the wheelchair cannot lie flat, and the leg support rod 22 can be adjusted to be parallel to the seat 5, and the foot rest 23 can be adjusted to be parallel to the seat 5, and the lower half of the patient can be supported by the foot rest 23 and the leg rest 24, so as to further ensure the comfort of the patient when lying flat.

[0041] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
