[0027] To make the objectives, features, and advantages of this disclosure more apparent and understandable, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0028] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0029] Reference Figures 1-4As shown, an exemplary embodiment of the present disclosure discloses a potty transfer mechanism, including a support 1, a potty 2, a cover 3, a slide 4, a connecting assembly 5, a linkage assembly 6, and a drive assembly 7. The slide 4 is fixedly connected to the support 1. One end of the connecting assembly 5 is slidably connected to the slide 4, and the other end is connected to the cover 3, for moving the cover 3. The potty 2 and the cover 3 are respectively connected to the linkage assembly 6. One end of the connecting assembly 5 that is slidably connected to the slide 4 is connected to the drive assembly 7, for driving the connecting assembly 5 to slide along the slide 4 and link with the linkage assembly 6, so that the potty 2 and the cover 3 are alternately positioned in a use position.

[0030] In this embodiment, the slide 4 serves as a guide for the movement of the connecting component 5, ensuring stable and smooth sliding of the connecting component 5. The slide 4 is fixed to the bracket 1, providing a stable foundation for the entire pot-moving mechanism. The connecting component 5 transmits power and facilitates the position change of the cover plate 3. Under the action of the drive component 7, the connecting component 5 slides along the slide 4, thereby moving the connected cover plate 3. The connecting component 5 and the slide 4 can be connected by components including, but not limited to, sliders or rollers. The pot 2 and the cover plate 3 are connected by a linkage assembly 6. When the connecting component 5 moves the cover plate 3, the linkage assembly 6 can, according to the motion relationship, link the pot 2, causing the pot 2 and the cover plate 3 to alternately reach the usage position. The drive component 7 can be, but is not limited to, an electric push rod or a motor, and can be selected according to actual needs and usage scenarios, as long as it can drive the connecting component 5. In the embodiments disclosed herein, the driving component 7 is an electric push rod as an example. During actual operation, the bedpan mechanism drives the connecting component 5 to slide along the slide rail 4. The connecting component 5 moves the cover plate 3, and simultaneously, the cover plate 3 is linked by the connecting rod component 6. When the driving component 7 retracts and pulls the connecting component 5 to move the cover plate 3 towards the usage position, the bedpan 2 automatically moves away from the usage position. When the driving component 7 extends and pushes the connecting component 5 to move the cover plate 3 out of the usage position, the bedpan 2 automatically moves towards the usage position. The specific location of the usage position can be adaptively designed according to the usage scenario, typically corresponding to the position of the user's buttocks during use. It should be noted that the slide rail 4 of this disclosure has two sets, which are arranged opposite to each other. The bedpan 2 and the cover plate 3 are both located between the two sets of slide rails 4.

[0031] In summary, the pot-moving mechanism disclosed herein ensures smooth movement through the coordinated design of the slide 4 and the connecting component 5, avoiding shaking and jamming. Through the cooperation of the slide 4, the connecting component 5, the linkage component 6, and the drive component 7, the smooth switching between the pot 2 and the lid 3 is achieved. The structure is simple, occupies little space, and has low maintenance costs.

[0032] In one embodiment, the connecting component 5 includes a roller assembly 51, which is disposed in the slide groove 41 of the slide rail 4. The driving component 7 is connected to the roller assembly 51 to drive the roller assembly 51 to move in the slide groove 41.

[0033] In this embodiment, there are two sets of rolling rollers 51, each set corresponding to one of the two sets of slide rails 4. Each set of rolling rollers 51 typically consists of multiple rollers, which are evenly distributed at the contact points between the connecting component 5 and the slide rail 4, ensuring that the connecting component 5 is subjected to uniform force during movement. The material of the rollers can be selected according to actual needs, such as wear-resistant, high-strength engineering plastics or metals, to ensure that the rollers are not easily damaged during long-term use and can roll stably in the slide rails 41. The rolling rollers 51 convert sliding friction into rolling friction, reducing the friction between the connecting component 5 and the slide rail 4, making the alternating movement of the toilet bowl 2 and the cover 3 smoother and preventing jamming.

[0034] In one embodiment, the connecting component 5 further includes a first connector 52 and a driving connector 53. The driving component 7 is connected to the first connector 52 through the driving connector 53. The roller group 51 includes a first roller 511, which is disposed on the first connector 52.

[0035] In this embodiment, the drive connector 53 specifically includes a U-shaped sheet metal part 531 and a U-shaped sheet metal connector 532. These two parts cooperate to stably transmit the power of the drive assembly 7 to the first connector 52. Preferably, each set of rolling rollers 51 contains two first rollers 511. The first rollers 511 are mounted on the first connector 52 and roll in the groove 41 of the slide rail 4, driving the entire connecting assembly 5 to move along the slide rail 4. When the drive assembly 7 is activated, the power it generates is transmitted to the first connector 52 through the U-shaped sheet metal part 531 and the U-shaped sheet metal connector 532, thereby driving the two sets of first rollers 511 located at both ends of the first connector 52 to roll in the groove 41 of the slide rail 4. The rolling of the first rollers 511 pushes the connecting assembly 5 to move, and the connecting assembly 5 then drives the connected cover plate 3 to move. Through the linkage of the linkage assembly 6, the alternating movement of the toilet bowl 2 and the cover plate 3 is realized.

[0036] In one embodiment, the connecting assembly 5 further includes a connecting rod assembly 54, one end of which is hinged to the first connecting member 52 and the other end of which is hinged to the cover plate 3.

[0037] In this embodiment, there are two sets of connecting rod assemblies 54, which are respectively located on both sides of the cover plate 3. When the drive assembly 7 drives the first connecting member 52 to move through the drive connector 53, the first roller 511 on the first connecting member 52 rolls in the groove 41 of the slide rail 4, pushing the connecting assembly 5 to move as a whole. At this time, the connecting rod assembly 54, which is hinged to the first connecting member 52, will rotate as the first connecting member 52 moves. Since the other end of the connecting rod assembly 54 is hinged to the cover plate 3, the connecting rod assembly 54 can drive the cover plate 3 to perform corresponding movements. It should be noted that in the actual production process, by reasonably designing the length of the connecting rod assembly 6 and the position of the hinge point, the movement path of the cover plate 3 can be precisely controlled to ensure the synchronicity of the toilet bowl 2 and the cover plate 3 during the movement, so that they can accurately alternate in the use position.

[0038] In one embodiment, the connecting rod assembly 54 includes a first connecting rod 541 and a second connecting rod 542 arranged in parallel. The second connecting rod 542 is hinged to the cover plate 3 through a second connecting member. The rolling wheel assembly 51 also includes a second roller 512. The second connecting member is connected to the slide rail 4 through the second roller 512. The connecting rod assembly 54 is hinged to the second connecting member through the second roller 512.

[0039] In this embodiment, one end of the first connecting rod 541 and the second connecting rod 542 is hinged to the first connecting member 52, and can move synchronously with the movement of the first connecting member 52. The connecting rod assembly 6 is hinged to the second connecting member through the second roller 512, so that the connecting rod assembly 6 can work in coordination with the second connecting member. When the position of the second connecting member changes, it drives the connecting rod assembly 6 to move, thereby realizing the linkage between the toilet bowl 2 and the cover plate 3.

[0040] In one embodiment, the chute 41 includes a first section 411 and a second section 412. The first section 411 is arranged in a horizontal direction, and the second section 412 is connected to the end of the first section 411 near the toilet bowl 2. The included angle between the first section 411 and the second section 412 is not less than 90°.

[0041] In this embodiment, taking the initial state where the cover 3 is in the use position as an example, when the drive assembly 7 drives the roller assembly 51 to move, the roller assembly 51 first moves along the second section 412 slide groove 41. At this time, the connecting assembly 5 drives the cover 3 to move downward. As the roller assembly 51 moves to the first section 411 horizontal slide groove 41, the connecting assembly 5 drives the cover 3 to move horizontally, making room for the entry of the bedpan 2, allowing the bedpan 2 to smoothly approach the user's body and reach the appropriate use position. During the closing process of the cover 3, the movement sequence is reversed as described above, and the bedpan 2 and cover 3 return along a predetermined path, which will not be elaborated here. Through the design of the slide groove 41 structure, the position and direction of the two slide grooves 41 are rationally planned, replacing the traditional method of rotating to open the cover 3. This allows the cover 3 to move downward first and then move horizontally, avoiding the risk of the mattress getting stuck. Furthermore, it achieves efficient movement of the bedpan 2 and cover 3 within a limited space, which helps to realize the miniaturization and multi-functional design of the mechanism.

[0042] In one embodiment, the connecting component 5 further includes an auxiliary wheel set 55, which is disposed on the first connecting member 52 and is used to limit the first connecting member 52.

[0043] In this embodiment, there are two sets of auxiliary wheel sets 55, which are respectively disposed at both ends of the first connecting member 52. When the drive assembly 7 drives the first connecting member 52 to move through the drive connecting member 53, the first roller 511 rolls in the groove 41 of the slide rail 4, causing the first connecting member 52 to move along the slide rail 4. At this time, the auxiliary wheel sets 55 contact the side of the slide rail 4, and through the rolling friction between them and the side of the slide rail 4, the lateral swaying and offset of the first connecting member 52 during the movement are limited. By setting the auxiliary wheel sets 55, the connecting assembly 5 is made more stable during the movement, and the reliability of the transfer mechanism is improved.

[0044] In one embodiment, the linkage assembly 6 includes a first linkage group 61 and a second linkage group 62. One end of the first linkage group 61 is hinged to the bracket 1 and the other end is connected to the toilet bowl 2. One end of the second linkage group 62 is hinged to the first linkage group 61 and the other end is hinged to the cover plate 3.

[0045] Furthermore, in one embodiment, the first linkage group 61 includes a support frame 611 and at least two first rods 612. The two first rods 612 are respectively disposed on both sides of the support frame 611 and are hinged to the support frame 611. The other end of the two first rods 612 is hinged to the bracket 1.

[0046] In this embodiment, the support frame 611 is used to support the toilet bowl 2, and the toilet bowl 2 is detachable from the support frame 611. The first linkage group 61 includes at least one first rod 612 disposed on both sides of the support frame 611. It should be noted that, in order to maintain the stable movement of the support frame 611, the two first rods 612 should be arranged to avoid being symmetrically arranged relative to the support frame 611, so that the hinge points of the two first rods 612 and the support frame 611 are staggered to prevent the support frame 611 from rotating freely. It can be understood that the first linkage group 61 may also include two second rods 613, which are disposed on both sides of the support frame 611 and hinged to the support frame 611, and the other end of the two second rods 613 is hinged to the bracket 1. The two second rods 613 are respectively disposed corresponding to the first rod 612 on the other side of the support frame 611 to enhance the stability of the support frame 611. The number of links in the second linkage group 62 can be one or two symmetrically arranged; when the number of links in the second linkage group 62 is one, preferably, the second link is arranged in the longitudinal plane where the center line of the support frame 611 is located, so as to ensure the stability of the movement process.

[0047] This disclosure also provides a nursing bed, which is provided with a transfer mechanism as described in any of the above-described embodiments.

[0048] In this embodiment, the support 1 of the bed-moving mechanism is fixed to the bed frame of the nursing bed, and its position is located below the bedpan opening on the nursing bed. Because the nursing bed is equipped with a bed-moving mechanism, the coordinated design of the slide 4 and connecting component 5 ensures smooth movement and avoids shaking and jamming. Through the cooperation of the slide 4, connecting component 5, connecting rod assembly 6, and drive assembly 7, the smooth switching between the bedpan 2 and the cover 3 is achieved. The structure is simple, occupies little space, and has low maintenance costs.
