[0021] The technical solutions of the present utility model 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 the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0022] A multi-functional wheelchair bed for toileting and showering, see attached document. Figure 1 and attached Figure 2As shown, the bathtub includes a bathtub body 1, which has a split structure and the two split bathtub bodies 1 are detachably connected; the bottom of the bathtub body 1 is provided with a bottom shell 2, which has a split structure and the split center line is on the same straight line as the split center line of the bathtub body 1; and a lifting wheel assembly 3 that can extend to the outside of the bottom shell 2 or be stored inside the bottom shell 2 is installed in one of the split bottom shells 2; a toilet bowl 5, a front flip-up plate assembly 6 and a middle seat assembly 7 are provided in one of the split bathtub bodies 1, and a ramp 4 and a rear flip-up plate assembly 8 are provided in the other split bathtub body 1, and the rear plate 81 flips onto the ramp 4 to form a footrest structure, and the front flip-up plate assembly 6, the middle seat assembly 7 and the rear flip-up plate assembly 8 can be converted to form a bed structure, a toilet structure, a bathtub structure or a wheelchair structure.

[0023] When the front flip-up panel assembly 6, the middle seat assembly 7, and the rear flip-up panel assembly 8 are in a horizontal state, a bed structure is formed; when the front flip-up panel assembly 6 is in a horizontal state, the middle seat assembly 7 moves between the toilet bowl body 5 and the front flip-up panel assembly 6, and the rear flip-up panel assembly 8 is in a horizontal state, a toilet structure is formed; when the front flip-up panel assembly 6 is in a horizontal state, the middle seat assembly 7 moves between the toilet bowl body 5 and the front flip-up panel assembly 6, and the rear flip-up panel assembly 8 is in an inward flip-up state, a bathtub structure is formed; when the front flip-up panel assembly 6 is in an outward flip-up state, the middle seat assembly 7 moves between the toilet bowl body 5 and the front flip-up panel assembly 6, the two separate bathtub bodies 1 separate, and the lifting wheel assembly 3 extends to the outside of the bottom shell 2, a wheelchair structure is formed.

[0024] In the specific implementation of this utility model, both the bathtub body 1 and the bottom shell 2 adopt a split structure, and the center lines of the split parts coincide. This design provides a basic framework for realizing multiple functions, allowing the components to be flexibly combined and operated. The lifting wheel assembly 3 installed in one of the split bottom shells 2 can extend to the outside of the bottom shell 2 when needed, providing mobility for forming a wheelchair structure. When not in use, it can be stored inside the bottom shell 2 without affecting the use in other functional states, ensuring the compactness of the overall structure and the convenience of multi-functional conversion. The following are the formation states of each structure:

[0025] Bed structure formation: When the front, middle and rear flip-up panel assemblies 8 are all in a horizontal state, each flip-up panel is spliced ​​together to form a plane, which constitutes the bed structure, allowing users to lie down and rest.

[0026] Toilet structure formation: the front flip plate assembly 6 remains horizontal, the middle seat plate assembly 7 moves between the toilet bowl body 5 and the front flip plate assembly 6, and the rear flip plate assembly 8 is also horizontal. At this time, the user is in a suitable position in the toilet bowl body 5, which is convenient for the user to use the toilet. Each flip plate works together to support the user's body.

[0027] Bathtub structure: The front flip-up plate assembly 6 is horizontal, the middle seat plate assembly 7 is located between the toilet body 5 and the front flip-up plate assembly 6, and the rear flip-up plate assembly 8 flips inward. After the rear flip-up plate assembly 8 flips inward, it together with other parts of the bathtub body 1 to form a relatively closed space. Together with the water storage of the bathtub body 1, it forms a bathtub structure to meet the user's showering needs.

[0028] Wheelchair structure formation: the front flip-up plate assembly 6 flips outward, the middle seat plate assembly 7 moves between the commode body 5 and the front flip-up plate assembly 6, the two separate bathtub bodies 1 separate, the lifting wheel assembly 3 extends out as a moving structure, the front flip-up plate assembly 6 flips outward as a wheelchair backrest structure, the separate bathtub bodies 1 separate and cooperate with the lifting wheel assembly 3, so that the whole has the mobility function of a wheelchair.

[0029] For the above scheme, please refer to the appendix. Figure 1 and attached Figure 2 As shown, electromagnetic plates 11 are provided on the opposite surfaces of the two separate bathtub bodies 1, so that the two separate bathtub bodies 1 are fixed together by electromagnetic adsorption. In this solution, the electromagnetic plates 11 provide a convenient and reliable way to connect the separate bathtub bodies 1. When the bathtub bodies 1 need to be combined into a complete bathtub structure for showering, simply powering on the electromagnetic plates 11 can quickly achieve a fixed connection between the two separate bathtub bodies 1, forming a stable water storage container. When the device needs to be converted to other functions, such as a wheelchair structure, the power supply to the electromagnetic plates 11 is cut off, the magnetic field disappears, the adsorption force between the two separate bathtub bodies 1 is released, and they can be easily separated, realizing the conversion between different functional structures. This fully demonstrates the synergistic advantages of the separate design and the electromagnetic connection method.

[0030] In another embodiment, for the connection between the two separate bathtub bodies 1, four funnels are installed on the opposite surfaces of the two separate bathtub bodies 1. Each funnel has an internal thread and a gear on the outer edge of the funnel. Each of the four gears is connected to a motor so that the motor operates to connect the funnels.

[0031] In addition, considering the sealing effect between the two separate bathtub bodies 1, therefore, refer to the attached... Figure 4As shown, rubber strips 12 are provided on the opposite surfaces of the two separate bathtub bodies 1, and the rubber strips 12 are located inside the electromagnetic plate 11. This allows the two separate bathtub bodies 1 to be sealed first by the sealing strips when connected, and then fixed by the adsorption of the electromagnetic plate 11. In this design, when the two separate bathtub bodies 1 begin to connect, the rubber strips 12, being inside the electromagnetic plate 11, will first come into contact and be squeezed. Under pressure, they can quickly fill the tiny gaps between the opposite surfaces of the separate bathtub bodies 1, achieving a preliminary sealing effect through their own deformation. After the rubber strips 12 complete the sealing action, the electromagnetic plate 11 is energized and activated. The strong adsorption force generated by the electromagnetic plate 11 not only firmly fixes the bathtub body 1, but also applies continuous and uniform lateral pressure to the rubber strips 12. This pressure makes the contact surface between the rubber strips 12 and the bathtub body 1 more compact, further enhancing the sealing effect and providing double protection for the sealing performance.

[0032] For the above scheme, please refer to the appendix. Figure 1 As shown, the lifting wheel assembly 3 includes a telescopic cylinder 31. Multiple telescopic cylinders 31 are vertically arranged inside one of the split bottom housings 2. The telescopic ends of the multiple telescopic cylinders 31 are connected to a mounting plate 32, and four wheels 33 are mounted on the mounting plate 32. In this design, when the telescopic cylinder 31 pushes the mounting plate 32 out of the bottom housing 2, the wheels 33 fall to the ground. The four wheels 33 are arranged in a reasonable manner to form the moving part of the wheelchair structure. In the implementation process, the wheels can be the existing power wheels, which are electrically connected to a control handle. The control handle can be used to make the power wheels perform actions. This method is a commonly used existing technology, and this utility model will not elaborate further on it.

[0033] For the above scheme, please refer to the appendix. Figure 1 As shown, the front-mounted tilting plate assembly 6 includes a front plate 61. The tail end of the front plate 61 is rotatably connected to one of the separate bathtub bodies 1, and it is hinged to the telescopic end of a telescopic cylinder 62, which is hinged to one of the separate bathtub bodies 1. In this design, the front plate 61 has a degree of freedom to tilt. When the telescopic cylinder 62 is activated, it begins to extend and retract according to its internal driving principle (such as hydraulic, pneumatic, or electric). At this time, the front plate 61 will be subjected to an upward force from the telescopic cylinder 62. Ultimately, the front panel 61 flips upward around the tail end. Conversely, when the telescopic cylinder 62 retracts, it flips downward back to the initial position. With the extension and retraction of the telescopic cylinder 62, the front panel 61 can achieve angle flipping to adapt to various functional states of the equipment, such as bed, toilet, bathtub, and wheelchair structure. For example, when the equipment is in bed structure, the telescopic cylinder 62 is adjusted to a suitable length so that the front panel 61 is stably in a horizontal state. When switching to wheelchair structure, the front panel 61 needs to be flipped upward at a certain angle to form a backrest structure.

[0034] For the above scheme, please refer to the appendix. Figure 1and attached Figure 3 As shown, the central seat assembly 7 includes a telescopic cylinder three 71, which is horizontally installed inside one of the separate bathtub bodies 1. Its telescopic end is connected to a fixed seat 72. A telescopic cylinder four 73 is vertically installed on the fixed seat 72. The telescopic cylinder four 73 is connected to a central plate 74, which has an opening 741. When the central plate 74 moves above the toilet bowl body 5, the opening 741 is coaxial with the inlet of the toilet bowl body 5. A telescopic cylinder five 75 is fitted at the opening 741. The telescopic cylinder five 75 is vertically installed inside the other separate bathtub body 1. A telescopic cylinder six 76 is horizontally installed at the telescopic end of the telescopic cylinder five 75. The telescopic cylinder six 76 is connected to a baffle plate 77 for blocking the opening 741, and the baffle plate 77 has a filling plate 78 for inserting into the opening 741. In this design, the telescopic... Cylinder 3 71 is horizontally installed inside one of the separate bathtub bodies 1. It is the starting power source for adjusting the position of the central seat assembly 7. When cylinder 3 71 extends, the central seat 74 can be on the same horizontal plane as the front seat 61. When cylinder 3 71 retracts, the central seat 74 moves down. With the retraction of cylinder 4 73, the central seat 74 can be moved between the toilet bowl body 5 and the front seat 61, and the opening 741 is directly above the inlet of the toilet bowl body 5, ensuring that excrement can smoothly enter the toilet bowl body 5 when the user uses the toilet function. At the same time, cylinder 5 75 retracts, driving the baffle 77 down, causing the filling plate 78 to disengage from the opening 741. Cylinder 6 76 retracts, moving the baffle 77 away, exposing the opening 741, which cooperates with the inlet of the toilet bowl body 5 to realize the toilet function.

[0035] For the above scheme, please refer to the appendix. Figure 1 As shown, the rear-mounted flip-up panel assembly 8 includes a rear panel 81. The rear end of the rear panel 81 is rotatably connected to another split bathtub body 1, and it is hinged to the telescopic end of a telescopic cylinder 82, which is hinged to another split bathtub body 1. In this design, the rear panel 81 has a degree of freedom to flip. When the telescopic cylinder 82 is activated, it extends according to its internal driving principle (such as hydraulic, pneumatic, or electric). At this time, the rear panel 81 will be subjected to an upward force from the telescopic cylinder 82, which will eventually keep the rear panel 81 in a horizontal state. Conversely, when the telescopic cylinder 82 retracts, the rear panel 81 flips downward. By extending and retracting the telescopic cylinder 82, the rear panel 81 can achieve angle flipping to adapt to various functional states of the equipment, such as bed, toilet, bathtub body 1, and wheelchair structure. For example, when the equipment is in a bed structure, the telescopic cylinder 82 is adjusted to a suitable length so that the front panel 61 is stably in a horizontal state, and the rear panel 81 flips onto the inclined platform 4 to form a footrest structure.
