The nursing bed chair 10 includes a bed frame 11 and a movable bed body 12.

The bed frame 11 includes a bed frame frame 111 and a bed frame leg 112 disposed below the bed frame frame 111. The bed frame leg 112 is used to support the bed frame frame 111.

The movable bed body 12 is detachably connected to the bed frame 11. The movable bed body 12 includes: a backrest board assembly 121, a seat backrest board assembly 122, a first connection piece 20 connecting the backrest board assembly 121 and the seat backrest board assembly 122, a leg rest board assembly 123, and a connection between the leg rest board assembly 123 and The second connection piece 30 of the seat plate assembly 122, the first connection piece 20 is used to rotate the seat back plate assembly 121 relative to the seat plate assembly 122, and the second connection piece 30 is used to make the leg rest plate assembly 123 relative to the chair The seat plate assembly 122 rotates.

Specifically, the movable bed body 12 can be folded to realize the mutual conversion between the two forms of the nursing bed and the nursing wheelchair. In the form of nursing a bed, the chair backboard assembly 121, the chair seat panel assembly 122, and the leg support board assembly 123 are all flush with the bed frame frame 111 and snap-connected with the bed frame frame 111. As shown in FIG. 2, the first connecting member 20 is used to rotate the seat back plate assembly 121 relative to the seat seat plate assembly 122 to obtain a nursing bed chair 10 in the form of a nursing wheelchair. As shown in FIG. 3, the second connecting member 30 is used to rotate the leg support plate assembly 123 relative to the seat plate assembly 122 to obtain a nursing bed chair 10 that assists a caregiver in flexing and stretching the legs. It should be noted that the nursing bed chair 10 has sufficient structural stability in the form of a nursing bed or a wheelchair, and does not affect the physical feeling of the care target and cause discomfort. When separating and docking the seat back plate assembly 121, seat seat plate assembly 122, and leg rest plate assembly 123, it is only necessary to ensure that the seat seat plate assembly 122 is flush with the bed frame frame 111, and the seat back plate assembly 121 and the leg rest plate assembly 123 are free to move.

Further, in the form of a nursing wheelchair, the nursing bed and chair control system can also be adjusted to a wheelchair mode, and the algorithm in the wheelchair mode can be loaded. Use the control panel to set the system to follow the target or specify the destination. The wheelchair performs the control operation according to the algorithm to automatically follow the target or go to the destination. During the travel, the built-in algorithm automatically detects the slope of the road, determines the braking scheme and seat back angle for the initial slope, and also determines when the slope changes, to ensure that the care target does not fall out of the wheelchair due to physical imbalance. Detects and monitors the physical condition of the care object throughout the process. When the detection value reaches the set critical point, a warning is sent to the processor to ensure that the care object cannot detect unexpected problems in time because it is not in the visual range.

Different from the situation in the prior art, the nursing bed chair 10 provided in this embodiment includes a movable bed body 12 detachably connected to the bed frame 11, and the movable bed body 12 includes: a chair back plate assembly 121 and a chair seat plate assembly. 122.

It cooperates with the T-shaped groove 111t and rolls in the T-shaped groove 111t to realize the detachable connection between the movable bed body 12 and the bed frame 11.

Referring to FIG. 1 and FIG. 8, FIG. 8 is a schematic diagram of a third partial structure of a nursing bed chair provided by an embodiment of the present application. The bed frame frame 111 further includes a baffle 81, a spring 82, a first wedge 83, a second wedge 84, a take-up wheel 85, and a motor control switch 86.

The baffle 81 is slidably disposed inside the T-shaped groove 111t, and the baffle 81 is in contact with one side of the roller 120d.

The spring 82 is disposed inside the T-shaped groove 111t, one end of which is connected to the bed frame frame 111 and the other end of which is connected to the baffle 81, and is used to control the sliding of the baffle 81.

The first wedge 83 protrudes from the lower edge of the T-shaped groove 111t and abuts on the other side of the roller 120d. The first wedge 83 is used to cooperate with the baffle 81 to restrict the rolling of the roller 120d. The first wedge 83 is provided with a positioning groove 831.

The second wedge 84 is disposed below the T-shaped groove 111t. One end of the second wedge 84 matches the shape and size of the positioning groove 831. The second wedge 84 is used to cooperate with the positioning groove 831 to limit the first wedge 83. Located at the lower edge of the T-shaped groove 111t.

The take-up wheel 85 is fixedly disposed below the bed frame frame 111. The take-up wheel 85 includes a first gear 851, and a first reel 852 and a second reel 853 connected to the first gear 851.

The baffle 81 and the spring 82 mainly play a role of limiting the displacement and cushioning in the negative direction. If only the T-shaped groove 111t is used to limit the displacement of the roller 120d, a more significant impact may be generated.

When separated, the angle of the back plate assembly 121 changes to a first preset angle (for example, 80 degrees, which can be set), and the leg rest plate assembly 123 drops to a second preset angle (for example, -55 degrees, which can be set), and The pedal (not shown) can be adjusted to a third preset angle (the included angle with the leg support plate assembly 123 can be 0 degrees and can be set). The motor drives the first gear 851 to rotate counterclockwise, and releases the restriction on the displacement of the first wedge 83. The first wedge 83 is pulled down and finally caught by the first wedge 83. The displacement restriction of the roller 120d is lifted, and it moves outward along the T-shaped groove 111t. The motor control switch 86 is popped up, and the control function of the motor control switch 86 is reset. At this time, the nursing bed chair 10 is in the form of a nursing wheelchair.
