[0029] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions 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 only 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.

[0030] An embodiment of the present invention provides a lifting structure, including a toilet hole frame assembly, a driving assembly, a telescopic assembly and a toilet bowl frame assembly; when not in use, the toilet hole frame assembly fills the toilet hole to prevent the toilet hole from collapsing; when in use, the toilet hole frame assembly and the toilet bowl frame assembly are switched in position so that the toilet bowl supported by the toilet bowl frame assembly fits in the toilet hole to prevent excrement from splashing out; and the position switching between the toilet hole frame assembly and the toilet bowl frame assembly is driven by the driving assembly and the telescopic assembly.

[0031] The following describes in detail the components of the lifting structure provided by the embodiment of the present invention, as well as the positional relationship and connection relationship between the components, in conjunction with the accompanying drawings.

[0032] like Figures 1 to 4 As shown, in the embodiment of the present invention, the toilet hole frame assembly 10 includes a toilet hole support frame 11, a toilet hole frame body 12 and at least two toilet hole support arms 13, one end of the toilet hole support arm 13 is rotatably connected to the toilet hole frame body 12, and the other end is rotatably connected to the toilet hole support frame 11.

[0033] When the toilet hole frame body 12 switches between the use state and the non-use state, it has a certain height difference, that is, when in the use state, the toilet hole frame body 12 needs to be lifted to a certain height and filled / inserted into the toilet hole to achieve blocking of the toilet hole and avoid collapse at the toilet hole position.

[0034] For example, the contour shape of the toilet hole frame body 12 is the same as the shape of the toilet hole, and the gap between the contour edge of the toilet hole frame body 12 and the inner edge of the toilet hole is small to avoid depression caused by the gap. For example, the straight-line distance of the gap is less than 10 mm.

[0035] When in use, the toilet hole frame body 12 is supported at a certain height by the toilet hole support arm 13, and the toilet hole frame body 12 is at the supporting position. When not in use, the rotation positions of the toilet hole frame body 12, the toilet hole support arm 13 and the toilet hole support frame 11 rotate with each other, so that the toilet hole support arm 13 drives the toilet hole frame body 12 to move toward the toilet hole support frame 11, and finally, the toilet hole frame body 12 moves to the retracted position.

[0036] For example, the rotation connection method includes a rotating shaft 14. Both ends of the toilet hole support arm 13 are rotationally connected to the toilet hole frame body 12 and the toilet hole support frame 11 through the rotating shaft 14 respectively.

[0037] Continue to refer Figures 1 to 4 As shown, in the embodiment of the present invention, the driving assembly 20 is connected to the fecal hole support frame 11, and is used to drive the fecal hole support frame 11 to reciprocate along a set direction; the set direction can be understood as: the fecal hole support frame 11 in the fecal hole frame assembly 10 will move under the action of the driving assembly 20, and realize the position switching between the supporting position and the retracted position.

[0038] For example, the driving assembly 20 includes a linear driving device 21 and two slide rails 22; the two slide rails 22 are parallel and spaced apart, and the slide rails 22 are connected to the bed frame 50. For example, both ends of the slide rails 22 are respectively connected to the bed frame 50 through a supporting structure. The plane where the slide rails 22 are located is parallel to the plane where the bed board of the bed frame 50 is located and spaced apart. The two side ends of the toilet hole support frame 11 are respectively arranged on the slide rails 22 and are slidably connected to the slide rails 22. For example, rollers are arranged at the bottom of the two side ends of the toilet hole support frame 11, and tracks for limiting the position of the rollers are arranged on the slide rails 22. Through the cooperation of the rollers and the tracks, the reciprocating movement of the toilet hole support frame 11 on the slide rails 22 is realized.

[0039] The linear drive device 21 is connected to the toilet hole support frame 11, and is used to drive the toilet hole support frame 11 to reciprocate along the slide rail 22. For example, the linear drive device 21 is arranged above a slide rail 22, and the driving direction of the linear drive device 21 is the same as the length direction of the slide rail 22. The linear drive device 21 includes a linear screw and a drive motor, the output shaft of the drive motor is connected to one end of the linear screw, and the other end of the linear screw is connected to a bearing, wherein the housing of the drive motor is connected to the bed frame 50, the bearing is connected to a bearing seat, and the bearing seat is connected to the bed frame 50.

[0040] A nut is set on the screw, the nut is threadedly connected to the screw, and the bottom end of the nut is fixedly connected to the hole support frame 11 on the slide rail 22. As the screw rotates forward or reverse, the nut on the screw can be driven to move forward or reverse, thereby driving the hole support frame 11 to reciprocate on the slide rail 22.

[0041] Continue to refer Figures 1 to 4As shown, in the embodiment of the present invention, the telescopic assembly 30 is used to telescope along the moving direction of the toilet hole support frame 11, one end of the telescopic assembly 30 is connected to one of the toilet hole support arms 13, and the other end is used to connect to the bed frame 50. By setting the telescopic assembly 30, when the toilet hole frame body 12 moves to the supporting position, the telescopic assembly 30 cooperates with the driving assembly 20 to complete the lifting and lowering operation of the toilet hole frame body 12.

[0042] The telescopic component 30 includes one or more of a cross rod, a spring line, a steel wire rope, a folding arm or a telescopic rod. The two ends of the telescopic component 30 can be fixedly connected or rotatably connected to the portafilter arm 13 and the bed frame 50, respectively. For example, when using a structure such as a steel wire rope, it can achieve multi-degree-of-freedom movement. Therefore, the two ends of the steel wire rope can be fixedly connected. When using a cross rod structure, it can be telescopic along the length direction, while the degree of freedom of movement in the height direction is limited. Therefore, such a structure can be set as a rotation connection. For example, the telescopic component 30 is rotatably connected to the portafilter arm 13 and the bed frame 50 through a rotating shaft.

[0043] When the toilet hole frame body 12 is in the supporting position, the telescopic assembly 30 is in an extended state, and the toilet hole support arm 13 is in a supporting state. When moving from the supporting position to the retracted position, as the screw rotates, the toilet hole support frame 11 moves, and the toilet hole support arm 13 tilts as the toilet hole support frame 11 moves, thereby driving the toilet hole frame body 12 to descend, wherein the toilet hole support arm 13 tilts to the side away from the telescopic assembly 30. In this state, the telescopic assembly 30 is not retracted. As the screw continues to rotate, the toilet hole support frame 11 continues to move, thereby causing the telescopic assembly 30 to fold and retract until the toilet hole frame body 12 moves to the retracted position.

[0044] When the toilet hole frame body 12 moves from the retracted position to the supporting position, each component can be moved in the reverse direction.

[0045] For example, in the structure of the manhole support arm 13, the axis direction of the rotating shaft 14 connected to the manhole support arm 13 is perpendicular to the moving direction of the manhole support frame 11. A torsion spring 15 is provided on at least one rotating shaft 14 at both ends of the manhole support arm 13; by providing the torsion spring 15, an auxiliary supporting force can be provided for the manhole support arm 13.

[0046] Specifically, when the toilet hole frame body 12 is in the supporting position, the torsion spring 15 is deformed and applies a force in the direction of the telescopic assembly 30 to the toilet hole support arm 13, and under the action of the torsion spring 15 and the telescopic assembly 30, the toilet hole frame body 12 is maintained at the first height; when the toilet hole frame body 12 is in the contracted position, the torsion spring 15 is reset and releases the stress to the toilet hole support arm 13, and under the action of the torsion spring 15 and the telescopic assembly 30, the toilet hole frame body 12 is maintained at the second height.

[0047] Continue to refer Figures 1 to 4As shown, in the embodiment of the present invention, the bedpan frame assembly 40 is located on the side of the toilet hole support frame 11 away from the telescopic assembly 30; the bedpan frame assembly 40 includes a bedpan frame body 41, a first connecting rod 42 and a second connecting rod 43, one end of the first connecting rod 42 is rotatably connected to the toilet hole support frame 11, and the other end is rotatably connected to the bedpan frame body 41, one end of the second connecting rod 43 is rotatably connected to the bedpan frame body 41, and the other end is used to be rotatably connected to the bed frame 50.

[0048] For example, the toilet bowl rack body 41 includes a load-bearing end surface for placing the toilet bowl 60. For example, an anti-slip layer is provided on the load-bearing end surface to improve the stability of the placement of the toilet bowl 60. A stop structure is provided at the edge of the load-bearing end surface to limit the toilet bowl 60.

[0049] The ends of the first connecting rod 42 and the second connecting rod 43 are connected to the connected structure by bolts or the like, thereby realizing a rotational connection. As the toilet hole support frame 11 reciprocates, the first connecting rod 42 is reciprocatedly stretched, and the second connecting rod 43 moves synchronously, thereby realizing the lifting and lowering operation of the toilet bowl frame body 41 and the toilet bowl 60. Among them, the lifting and lowering height of the toilet hole support frame 11 and the toilet bowl 60 is determined according to the length of the first connecting rod 42 and the second connecting rod 43, and the moving distance of the toilet hole support frame 11. In the embodiment of the present invention, after the toilet bowl 60 is raised, the port of the toilet bowl 60 can be fitted with the toilet hole.

[0050] For example, the toilet stand assembly 40 includes two groups of first connecting rods 42 and second connecting rods 43; the two groups of first connecting rods 42 and second connecting rods 43 are respectively located on both sides of the toilet stand body 41; the two first connecting rods 42 are respectively rotatably connected to the two ends of the connection side of the toilet hole support frame 11; the space between the two groups of first connecting rods 42 and second connecting rods 43 forms a toilet taking and placing space.

[0051] The toilet bowl 60 is located under the bed and needs to be pulled out and placed horizontally. One end of the toilet bowl frame body 41 is the driving assembly 20 and the toilet hole frame assembly 10, and two groups of first connecting rods 42 and second connecting rods 43 are respectively provided on both sides. Therefore, a toilet bowl placement space is formed at the other end of the frame body, which can facilitate the placement operation of the toilet bowl 60.

[0052] For example, vertical frames 44 are respectively provided on both sides of the toilet stand body 41, and the vertical frames 44 are arranged along the direction perpendicular to the surface of the toilet stand body 41; the other end of the first connecting rod 42 is rotatably connected to the bottom end of the vertical frame 44, and one end of the second connecting rod 43 is rotatably connected to the top end of the vertical frame 44. The vertical frame 44 is equivalent to one of the connecting rod structures. With this arrangement, during the lifting process of the toilet stand body 41, the toilet stand body 41 can always be kept in a horizontal state, even if the potty 60 is in a horizontal state, thereby preventing the potty 60 from tilting during the lifting process.

[0053] For example, when the toilet hole frame body 12 moves from the supporting position to the retracted position, the toilet hole support frame 11 drives the first connecting rod 42 and the second connecting rod 43 to rotate, and lifts the toilet bowl frame body 41 to the set position. For example, the vertical frame 44 has a certain height, which is the same as the height at which the slide rail 22 is suspended on the bed frame 50. The set position can be understood as: the toilet bowl frame body 41 is lifted to a height flush with the toilet hole support frame 11 through the first connecting rod 42 and the second connecting rod 43, even when the hole frame body 12 is in the retracted position, the toilet bowl frame body 41 is lifted to the plane where the toilet hole support frame 11 is located.

[0054] like Figure 5 As shown, an embodiment of the present invention provides a nursing bed, including the above-mentioned lifting structure. When in use, the driving assembly 20 drives the toilet hole frame assembly 10 and the toilet bowl frame assembly 40 to move in conjunction, the toilet hole frame body 12 moves between the supporting position and the retracted position, and the toilet bowl frame body 41 moves synchronously with it. Specifically:

[0055] When the toilet hole frame body 12 is in the supporting position, the telescopic assembly 30 is in an extended state, and the toilet hole frame body 12 has a first height from the support frame 11 support surface. For example, the toilet hole support arm 13 is perpendicular to the support frame 11 support surface. The toilet hole frame body 12 is supported at a certain height and enters the toilet hole. The toilet hole is filled by the toilet hole frame body 12 to avoid collapse at the toilet hole position. Similarly, the toilet bowl frame body 41 is located on one side of the toilet hole support frame 11, the first connecting rod 42 and the second connecting rod 43 are not tightened, and the toilet bowl frame body 41 is in a lower position.

[0056] When the patient needs to perform a bowel movement, the driving component 20 is started, and the driving component 20 will pull the toilet hole support frame 11 to move. First, the toilet hole support arm 13 is folded, driving the toilet hole frame body 12 to descend, and then the telescopic component 30 is gradually retracted, and finally the toilet hole frame body 12 moves to the retracted position. The toilet hole frame body 12 has a second height from the support frame 11 support surface, for example, the toilet hole support arm 13 is parallel to and overlaps with the support frame 11 support surface; at the same time, with the movement of the toilet hole support frame 11, the first connecting rod 42 and the second connecting rod 43 are stretched, so that the bedpan frame body 41 is moved to the toilet hole position and is lifted to a certain height (oblique movement), and finally the port of the bedpan 60 is in contact with the bottom surface of the toilet hole.

[0057] When the patient completes the excretion action, the driving assembly 20 drives in reverse to reset the feces hole frame assembly 10 and the bedpan frame assembly 40, the feces hole frame body 12 fills the feces hole, and the bedpan frame body 41 drops to a certain height to facilitate taking the bedpan 60.

[0058] The present invention provides a lifting structure and a nursing bed, wherein the toilet hole support frame 11 can be switched between a supporting position and a retracted position under the action of a driving assembly 20, wherein when in the supporting position, the toilet hole frame body 12 is supported by the toilet hole support frame 11 to a certain height, and is used to fill the toilet hole position of the bed frame 50, and when in the retracted position, the toilet hole frame body 12 descends and separates from the toilet hole, and synchronously raises and moves the toilet bowl 60 to the toilet hole position, and fits the toilet bowl 60 to the toilet hole. The technical solution of the present invention is that the toilet hole frame assembly 10 fills the toilet hole and has good supporting strength to prevent the toilet hole position from collapsing when the nursing bed is in use, and the toilet bowl frame assembly 40 is lifted to a certain height when in use, and fits the toilet bowl 60 to the toilet hole to prevent excrement from overflowing; and the position switching of the toilet hole frame assembly 10 and the toilet bowl frame assembly 40 is controlled in a linkage manner, and the function switching is more stable and smooth, and the structural space can be optimized, the overall weight can be reduced, and the cost can be reduced.
