[0027] Referring to FIGS. 1 to 3, the present disclosure provides a nursing bed-chair assembly, which includes a nursing bed 100 and a wheelchair 200. Specifically, the nursing bed 100 includes a bed frame 110, a connecting mechanism 120 and a butt-joint mechanism 130, and the wheelchair 200 includes a wheelchair frame 210, a backrest 220, a seat plate 230, main wheels 240, armrests 250 and butt-joint portions 260. The connecting mechanism 120 and the butt-joint mechanism 130 are mounted on the bed frame 110. The backrest 220 and the seat plate 230 are mounted on the wheelchair frame 210, the main wheels 240 are rotatablely mounted on the wheelchair frame 210 and are located on both sides of seat plate 230, the armrests 250 are mounted on the wheelchair frame 210 retractably and are located at the two sides of the seat plate 230, connecting portions 251 are arranged at ends of the armrest 250, and the butt-joint portions 260 are arranged on both sides of a front end of wheelchair frame 210 and are located below the armrests 250. If a patient needs to transfer from the nursing bed 100 to the wheelchair 200, the wheelchair 200 is moved to the vicinity of the nursing bed 100, so that the butt-joint portions 260 are in butt-joint with the butt-joint mechanism 130, and the armrests 250 are extended and contracted to adjust the position between the connecting portions 251 and the connecting mechanism 120, so as to connect the connecting portions 251 with the connecting mechanism 120. After the connecting portions 251 are connected with the connecting mechanism 120 and the butt-joint portions 260 are in butt-joint with the butt-joint mechanism 130, upper and lower portions of a front end of the wheelchair 200 are connected with the nursing bed 100 respectively, forming a relatively stable structure. When the patient transfers from the nursing bed 100 to the wheelchair 200, the wheelchair 200 will not shift and shake, thereby ensuring the safety of the patient and avoiding the secondary injury to the patient.

[0028] Referring to FIGS. 2 to 4, in the present embodiment, the connecting mechanism 120 is a connecting tube hung on the bed frame 110. A lower portion of each of the connecting portions 251 of the armrests 250 is provided with an arc-shaped connecting opening 251a. When the armrests 250 are connected with the nursing bed 100, the connecting openings 251a of the connecting portions 251 overlap with the connecting tube, so that the wheelchair 200 cannot slide relative to the nursing bed 100, and thus the upper portion of the front end of the wheelchair 200 is connected with the nursing bed 100. Certainly, in addition to using the connecting openings 251a to connect with the connecting tube, the structures of the connecting portions 251 and the connecting mechanism 120 may be changed, then the connecting portions 251 and the connecting mechanism 120 may be connected by buckling, snap-fitting or clamping, and the connecting portions 251 and the connecting mechanism 120 may be connected by adhesion.

[0029] Referring to FIG. 2, in the present embodiment, the butt-joint mechanism 130 includes a guide rail 131, a butt-joint fixing plate 132 and butt-joint members 133. Two butt-joint members 133 are provided and are mounted on both sides of the butt-joint fixing plate 132, and the butt-joint fixing plate 132 is slidably mounted on the guide rail 131. Specifically, the guide rail 131 is provided with a slide block on which the butt-joint fixing plate 132 is mounted, and the guide rail 131 is mounted on the bed frame 110. The nursing bed 100 is further provided with a driving device which is electrically connected with the slide block and is capable of driving the slide block to slide. By driving the slide block to slide along the guide rail 131, relative positions between the butt-joint members 133 and the butt-joint portions 260 may be adjusted to ensure the butt joint between the nursing bed 100 and the wheelchair 200.

[0030] Specifically, in the present embodiment, the butt-joint portions 260 are magnets, and correspondingly, the butt-joint members 133 are electromagnets. The butt-joint portions 260 and the butt-joint members 133 are both two in number. The magnets are tied to the two sides of the front end of the wheelchair frame 210 and are located below the armrests 250. In the present embodiment, the butt-joint portions 260 are tied to the two sides of the front end of the wheelchair frame 210 of the wheelchair 200 in a binding manner, and the butt-joint portions 260 are detachable. If the butt-joint portions 260 are damaged, the butt-joint portions 260 may be replaced without replacing the whole wheelchair 200, reducing the maintenance difficulty. Of course, the butt-joint portions 260 may also be adhered to the wheelchair 200 by means of an adhesive or can be mounted on the wheelchair 200 by screws as well. If the patient needs to transfer from the nursing bed 100 to the wheelchair 200, the wheelchair 200 is moved to the vicinity of the nursing bed 100, the electromagnets are energized, and the slide block slides along the guide rail 131 to adjust the relative distance between the electromagnets and the magnets. The magnets gradually approach the electromagnets, and are attracted and fixed to the electromagnets to connect the lower portion of the front end of the wheelchair 200 with the nursing bed 100. The current passing through the electromagnets may be adjusted to change the magnetism of the electromagnets, so as to ensure the attraction strength between the electromagnets and the magnets, and prevent the wheelchair 200 from shifting and shaking due to the disengagement between the electromagnets and the magnets caused by an excessive force during the transfer of the patient to the wheelchair. Of course, the butt-joint portions 260 and the butt-joint members 133 may adopt the same structure as the connecting portions 251 and the connecting mechanism 120 respectively. The butt-joint portions 260 and the butt-joint members 133 may also be buckled, snap-fitted or adhered to connect the lower portion of the front end of the wheelchair 200 with the nursing bed 100.

[0031] Referring to FIG. 2, in order to facilitate the movement and transport of the nursing bed 100, the nursing bed 100 is further provided with pulleys 140 which are mounted at the bottom of the bed frame 110. The nursing bed 100 can be moved and transported at random through the pulleys 140, making the use of the nursing bed 100 more convenient.

[0032] Referring to FIG. 3, in order to facilitate caregivers or family members to move the patient, handles 270 are mounted on the wheelchair frame 210 on both sides of the back of the backrest 220. In the present embodiment, the handles 270 are integrated with the wheelchair frame 210 into one piece. Of course, the handles 270 can be mounted on the wheelchair frame 210 by welding, and the handles 270 can also be mounted on the wheelchair frame 210 by connecting. The mounting mode of the handles 270 is not limited to this.

[0033] In the present embodiment, the backrest 220 is mounted on the wheelchair frame 210 in a wide strip shape. The backrest 220 is made of woven cloth, and an angle of the backrest 220 is not adjustable. Of course, the backrest 220 may be made of other materials, and the angle of the backrest 220 may be set to be adjustable to improve the comfort of the patient when using the wheelchair 200.

[0034] Referring back to FIG. 3, to further improve the comfort of the patient when using the wheelchair 200, a pedal 280 is mounted at the front end of the wheelchair frame 210, between the two interfacing portions 260. The pedal 280 is of a plate-shaped structure, and both sides of the pedal 280 are respectively connected with the wheelchair frame 210, so that the patient may put his/her feet on the pedal 280 without suspending the feet, thereby improving the comfort of the patient.

[0035] Meanwhile, the wheelchair 200 is also provided with universal wheels 290 which are rotatablely mounted at the front end of the wheelchair frame 210 and are located at the two sides of the interfacing portions 260. Two universal wheels 290 are provided. A moving direction of the wheelchair 200 may be adjusted through the universal wheels 290, making the use of the wheelchair 200 more flexible, and avoiding the secondary injury to the patient caused by the difficulty of changing the moving direction because of only having the main wheels 240.

[0036] Embodiments of the present disclosure are described above in detail with reference to the accompanying drawings. However, the present disclosure is not limited to the above embodiments. Within the scope of the knowledge possessed by those skilled in the technical field, various changes can be made without departing from the purpose of the present disclosure.
