[0026] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0027] As Figures 1 to 5 shown, a safe and reliable nursing bed includes a bed frame 1. A mattress 2 is arranged on the upper side of the bed frame 1. One side of the bed frame 1 is provided with a wheelchair docking recess A. One end inside the wheelchair docking recess A is provided with a lifting plate 3. The lifting plate 3 is rotatably connected to the bed frame 1 through a flipping support structure and forms a headrest part after being flipped upwards and flattened.

[0028] The lifting plate 3 of this nursing bed can be flipped upwards and flattened, so that the lifting plate 3 replaces the headrest part B1 of the wheelchair bed B, preventing the wheelchair bed B in the flattened state from tipping over when the user sits on the headrest part B1 of the wheelchair. Moreover, the lifting plate 3 flipped upwards and flattened can also be used as a folding table, which can endow the lifting plate with multi-functional features, with a simple structure and convenient use.

[0029] The lifting plate 3 includes a support bottom plate 31 fixedly connected to the flipping support structure. An elastic soft package 32 is connected to the support bottom plate 31. The elastic soft package 32 is flush with the mattress 2 when being flattened. The support bottom plate 31 can provide a hard bottom for the elastic soft package 32, facilitating the formation of a firm connection with the flipping support structure. The elastic soft package 32 forms a part of the mattress 2, making the user lie more comfortably.

[0030] One bedside side A1 and two opposite bed end sides A2 are provided on the wheelchair docking recess A. In this embodiment, the lifting plate 3 is rotatably connected to one of the bed end sides A2 of the wheelchair docking recess A (mainly the side near the head of the bed).

[0031] The bed frame 1 includes a head bed frame 11. At least a part of the head bed frame 11 is used to define the bed end side A2 of the wheelchair docking recess A. The lifting plate 3 is pivotally connected to the inner side of the head bed frame 11. When the lifting plate 3 is turned flat, the rear end side thereof is limited and abutted against the top surface of the head bed frame 11. When the lifting plate 3 is turned up flat, it plays a limiting role. In addition, the head bed frame 11 can directly support the lifting plate 3 to a certain extent, which helps to improve the load-bearing capacity of the lifting plate 3 and enhance the stability.

[0032] The width of the lifting plate 3 matches the width of the wheelchair docking recess A. Preferably, the width of the lifting plate 3 is the same as the width of the wheelchair docking recess A, so that the lifting plate 3 can match the width of the wheelchair after it is flattened, forming an integrated bed surface.

[0033] The flipping support structure includes two support brackets 4 connected to the bed frame 1. The two support brackets 4 are symmetrically connected to the left and right sides of the lifting plate 3. And a self-locking structure is provided on the support bracket 4. The two support brackets 4 can stably support the lifting plate 3, and the self-locking structure can lock the flattened state of the lifting plate 3.

[0034] Specifically, any one of the support brackets 4 includes;

[0035] A fixed support rod 41, which is longitudinally fixed on the bed frame 1;

[0036] A movable support rod 42, the lifting plate 3 is fixed on the outside of the movable support rod 42, and one end of the movable support rod 42 is rotatably hinged to the top end of the fixed support rod 41, and the other end is provided with a chute 421 along the length direction;

[0037] Two connecting rods 43, one ends of the two connecting rods 43 are connected by a first hinge shaft 431 and rotatably hinged to the lower part of the fixed support rod 41, and the other ends of the two connecting rods 43 are connected by a second hinge shaft 432 and are slidably connected to the chute 421 through the second hinge shaft 432.

[0038] When the above support bracket 4 is turned up flat or folded down, the second hinge shaft 432 can slide back and forth along the chute 421, with smooth sliding and simple operation. And a triangular structure is formed by using the connecting rod 43 to achieve support, with stable and firm support.

[0039] The length of the movable support rod 42 is greater than the length of the fixed support rod 41. The cross-sectional shapes of the fixed support rod 41 and the movable support rod 42 are both in a "U" shape structure, but the width of the movable support rod 42 is smaller than that of the fixed support rod 41. When the support bracket 4 is folded, the movable support rod 42 is embedded inside the fixed support rod 41, which can save space and make the lifting plate 3 fit closer to the bed end side. In addition, a notch 422 for making way for the first hinge shaft 431 is provided opposite to the movable support rod 42.

[0040] The self-locking structure includes a switch rocker 44, which is swingably connected below the chute 421 through a rotating shaft 45. A torsion spring 46 is sleeved on the rotating shaft 45, and both ends of the torsion spring 46 act on the movable support rod 42 and the switch rocker 44.

[0041] Under the action of the torsion spring 46, the switch rocker 44 is inclined relative to the movable support rod 42. Its inner end is limited and abutted against the movable support rod 42 and forms an "X" shape with the chute 421. When the lifting plate 3 is flattened, the second hinge shaft 432 slides from the outer end of the chute 421 to the inner end of the chute 421. The second hinge shaft 432 presses against the upper side of the switch rocker 44, thereby overcoming the action of the torsion spring 46 and smoothly sliding to the inner end of the chute 421. The lifting plate 3 is in the flattened position and the switch rocker 44 is reset. After the lifting plate 3 bears weight, the second hinge shaft 432 will be forced to slide from the inner end of the chute 421 to the outer end of the chute 421. However, at this time, the second hinge shaft 432 will be stuck on the lower side of the switch rocker 44, thus preventing the second hinge shaft 432 from moving forward. When the lifting plate 3 is manually flipped down, only need to hold the other end of the switch rocker 44 with both hands to make the switch rocker 44 return to a state parallel to the chute 421, then the lifting plate 3 can be folded.

[0042] End plates 5 are connected to both the head side and the tail side of the bed frame 1; the end plates 5 can protect the front and back of the nursing bed and act as guardrails. Embodiment 2:

[0043] The difference between Embodiment 2 and Embodiment 1 is that as Figure 6 shown, a bedside side A1 and two opposite bed end sides A2 are provided on the wheelchair docking recess A. The lifting plate 3 is rotatably connected to the bedside side A1 of the wheelchair docking recess A. The remaining structures and principles are the same as those in Embodiment 1 and will not be elaborated in detail here.
