[0037] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0038] like Figure 1 and Figure 2 As shown, the present invention provides an auxiliary turning mechanism, including: a bed board 1, a first roller structure and a second roller structure.

[0039] The first rolling roller structure is arranged on one side in the width direction of the bed board 1 through the first swinging structure 8, and includes an active roller 5 and a first driving member 16. The extension direction of the active roller 5 is parallel to the length direction of the bed board 1. The first driving member 16 is suitable for driving the active roller 5 to rotate. The first swinging structure 8 is suitable for driving the active roller 5 to swing in the first direction with the center line of the bed board 1 as the swinging center.

[0040] The second rolling roller structure is arranged on the other side of the bed board 1 in the width direction through the second swinging structure 7, and includes a driven roller 4. The extension direction of the driven roller 4 is parallel to the length direction of the bed board 1. The bed sheet 6 is suitable for being wound on the active roller 5 and extending to be wound on the driven roller 4. The second swinging structure 7 is suitable for driving the driven roller 4 to swing in a second direction opposite to the first direction with the center line of the bed board 1 as the swinging center.

[0041] When the bedridden person needs to turn over, the first swinging structure 8 or the second swinging structure 7 can be used to drive the active roller 5 or the driven roller 4 to swing. Taking the first swinging structure 8 driving the active roller 5 to swing as an example, the first swinging structure 8 drives the active roller 5 to swing in the first direction with the center line of the bed board 1 as the swinging center, and the bed sheet 6 wound on the active roller 5 moves synchronously, thereby turning the bedridden person in the first direction, thereby realizing the bedridden person turning over to face the first direction. Since the bedridden person changes his posture to lying on his side, the contact area between himself and the bed sheet 6 is reduced. At this time, the first driving member 16 can be started. The first driving member 16 drives the active roller 5 to rotate, and the bed sheet 6 moves under the winding of the active roller 5. At the same time, it can drive the driven roller 4 to rotate, so as to smoothly move the new bed sheet 6 under the bedridden person. When the bedridden person needs to change to a lying position, the second swinging structure 7 can be used to drive the driven roller 4 to swing, thereby driving the bedridden person to turn in the second direction to a lying position through the bed sheet 6. The bedridden person can be turned over to face the second direction by the cooperation of the second swing structure 7, the driven roller 4 and the bed sheet 6. When the bedridden person lies on his side facing the second direction, the bed sheet 6 can also be replaced by winding the bed sheet 6 by the active roller 5. Therefore, the auxiliary turning mechanism of the present invention can not only turn the bedridden person over, but also replace the bed sheet 6, thereby avoiding the occurrence of bedsores and promoting the physical recovery of the bedridden person.

[0042] like Figure 1 , Figure 2 and Figure 3 As shown, in this embodiment, the driven roller 4 is detachably arranged on the second swing structure 7, and the bed sheet 6 can be wound on the driven roller 4, and the winding size of the bed sheet 6 is at least twice the width of the bed board 1. The winding size refers to the length size along the winding direction of the driven roller, so that the used area of ​​the bed sheet 6 can be wound by the active roller 5, and the unused area can be slid onto the bed board 1, thereby completing the replacement of the bed sheet 6 under the bedridden person with a clean part, thereby avoiding the occurrence of bedsores. Of course, the winding size of the bed sheet 6 can also be 3 times, 4 times, 5 times or even more times the width of the bed board 1, which will not be listed here one by one.

[0043] like Figure 3 and Figure 4 As shown, in the present embodiment, a plurality of marking lines 9 are provided on the bed sheet 6, and the width of two adjacent marking lines 9 is greater than the width of the bed board 1, male Velcro 10 is sewn on the lower surfaces of both ends of the bed sheet 6, and female Velcro 10 is bonded to the driven roller 4 and the active roller 5. By setting the marking lines 9, when the active roller 5 collects the used bed sheets 6, it can judge whether the used bed sheets 6 have been completely collected by observing the marking lines 9.

[0044] like Figure 1 and Figure 3As shown, in the present embodiment, a supporting airbag 15 is installed in the middle of the bed board 1, and the supporting airbag 15 can be inflated and deflated, and the supporting airbag 15 is located above the bed sheet 6. When the elderly person turns over and lies on his side, the supporting airbag 15 is inflated. On the one hand, it provides preliminary support for the elderly person, making it convenient to lift up the elderly person to turn over and lie on his side when the bed sheet 6 rises. On the other hand, the support for the elderly person reduces the contact between the elderly person and the bed sheet 6, making it convenient for the active roller to roll up the bed sheet after use.

[0045] like Figure 1 and Figure 2 As shown, in this embodiment, the first swing structure 8 includes a first swing plate 3, one end of which is rotatably set on the side wall of the bed board 1 in the length direction through a rotating shaft, the rotating shaft is coaxial with the center line of the bed board 1, and the other end extends to one of the edges in the width direction of the bed board 1, and the two first swing plates 3 are respectively rotatably set on the opposite sides of the length direction of the bed board 1, and the active roller 5 is rotatably set on the other ends of the two first swing plates 3.

[0046] The second swing structure 7 includes a second swing plate 2, one end of which is rotatably set on the side wall of the bed board 1 in the length direction through a rotating shaft, and the other end extends to the other edge of the bed board 1 in the width direction. The two second swing plates 2 are rotatably set on the opposite sides of the length direction of the bed board 1 respectively, and the driven roller 4 is rotatably set on the other end of the two second swing plates 2. The driven roller 4 is detachably set on the other end of the two second swing plates 2.

[0047] It also includes: a lifting mechanism, and two sets of lifting mechanisms respectively drive the two first swing plates 3 and the two second swing plates 2 to swing.

[0048] For example, the lifting mechanism can drive the two first swing plates 3 to rotate along a first direction, which can be the counterclockwise direction of the angle shown in the figure. The lifting mechanism can also drive the two second swing plates 2 to rotate along a second direction, which can be the clockwise direction of the angle shown in the figure, thereby completing the action of turning over to different directions for the bedridden person.

[0049] The second swing plate 2 is provided with a slot for placing the end of the driven roller 4. A limit seat 11 is installed on the second swing plate 2 by bolts. The limit seat 11 can close the slot so that the driven roller 4 can rotate in the slot, thereby realizing a detachable arrangement of the driven roller 4, which is convenient for winding a clean sheet 6 around the driven roller 4.

[0050] like Figure 1 , Figure 5 and Figure 6 As shown, in this embodiment, the lifting mechanism includes:

[0051] Two tooth plates 17 are fixedly connected to the bottom surface of the bed board 1 and extend in a direction perpendicular to the bottom surface of the bed board 1 .

[0052] The two moving frames 18 are slidably disposed on the corresponding toothed plates 17 , respectively. The moving frames 18 are rotatably provided with gears 19 that cooperate with the toothed plates 17 .

[0053] One end of the two push rods 23 is hinged to the corresponding moving frame 18 , and the other end is hinged to the corresponding first swing plate 3 or the second swing plate 2 .

[0054] The double-axis motor 20 is arranged at the bottom of the bed board 1 and is located between the two moving frames 18 , and the output end of the double-axis motor 20 is in transmission cooperation with the gear 19 .

[0055] Taking turning over in the first direction as an example, the dual-axis motor 20 located on one side of the active roller 5 drives the gear 19 to rotate, the gear 19 is meshed with the toothed plate 17, and the gear 19 is slidably set on the toothed plate 17 with the cooperation of the moving frame 18. Therefore, when the dual-axis motor 20 drives the gear 19 to rotate, the gear 19 can drive the moving frame 18 to move along the height direction of the toothed plate 17. Since the push rod 23 is hinged between the moving frame 18 and the first swing plate 3, when the moving frame 18 moves upward, the push rod 23 can push the first swing plate 3 to rotate, so that the active roller 5 is raised, thereby lifting the bed sheet 6 located on the active roller 5. The raised bed sheet 6 can lift up the side of the elderly close to the active roller 5, making it easier for the elderly to turn over to face the first direction.

[0056] like Figure 6 As shown, a T-shaped groove is provided on the tooth plate 17, and a T-shaped slide bar 25 adapted to the T-shaped groove is fixedly connected to the inner side of the moving frame 18. The T-shaped groove and the T-shaped slide bar 25 limit the displacement of the moving frame 18 and the gear 19, so that the gear 19 can move along the tooth plate 17.

[0057] like Figure 2 and Figure 5 As shown, in this embodiment, a guide rod 21 extending in a direction perpendicular to the bottom surface of the bed board 1 is fixedly provided on the bottom surface of the bed board 1, and the dual-axis motor 20 is slidably set on the guide rod 21 through a guide sleeve 22. The guide rod 21 and the guide sleeve 22 limit the displacement of the dual-axis motor 20.

[0058] like Figure 1 , Figure 2 and Figure 3 As shown, in this embodiment, a first through groove and a second through groove are opened on the bed board 1, a first baffle 13 is placed in the first through groove, and a second baffle 12 is placed in the second through groove, and a cylinder 14 for pushing the first baffle 13 or the second baffle 12 upward is arranged under the bed board 1.

[0059] When turning a bedridden person over to lie on his side, the first baffle 13 or the second baffle 12 can be first pushed up by the cylinder 14. For example, when turning over in the first direction, the second baffle 12 needs to be raised, which plays a certain limiting role for the elderly during the turning process, thereby preventing the elderly from shifting on the bed sheet and being unable to quickly complete the turning over and lying on the side.

[0060] The present invention provides a turning device, comprising the above-mentioned auxiliary turning mechanism.

[0061] The present invention provides a turning bed, comprising the turning device described above, and also comprising support legs 24 fixedly supported on the four corners of the bottom of the bed board.
