Description

Technical Field

[0001] The present invention relates to the technical field of nursing equipment, and more particularly, to a multi-functional wheelchair bed for toileting and showering. Background Art

[0002] In the modern medical and nursing fields, there are increasingly high requirements for the life assistance equipment for people with limited mobility. Especially for users who are bedridden for a long time or have limb dysfunction, equipment that can simultaneously meet their daily rest, toileting, and showering needs is particularly important. The functions of traditional nursing equipment are often relatively single. For example, an ordinary hospital bed can only meet the needs of users to lie down and rest. When users need to use the toilet or take a shower, they need to rely on additional facilities, which not only makes the operation cumbersome but also increases the workload of nursing staff. At the same time, for users who need to be transferred frequently, there is a lack of equipment that can be flexibly converted into a wheelchair and has good mobility. The existing wheelchairs, beds, bathtubs, etc. with single functions are difficult to meet the rapid needs of users in different scenarios. Summary of the Invention

Detailed implementation manners

[0014] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention. The present invention will be further described in conjunction with the accompanying drawings and embodiments: A multi-functional wheelchair bed for toilet and shower, referring to the attached Figure 1 and the attached Figure 2 As shown, it includes a bathtub body 1. The bathtub body 1 is of a split structure, and the two split bathtub bodies 1 are detachably connected; a bottom housing 2 is provided at the bottom of the bathtub body 1. The bottom housing 2 is of a split structure and the split center line of the bottom housing 2 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 housing 2 or be received inside the bottom housing 2 is installed in one of the split bottom housings 2; a toilet body 5, a front flip plate assembly 6 and a middle seat board assembly 7 are arranged in one of the split bathtub bodies 1, and an inclined platform 4 and a rear flip plate assembly 8 are arranged in the other split bathtub body 1. And the rear plate 81 is flipped onto the inclined platform 4 to form a footrest structure, and the front flip plate assembly 6, the middle seat board assembly 7 and the rear flip plate assembly 8 can be converted into each other to form a bed structure, a toilet structure, a bathtub structure or a wheelchair structure.

[0015] Among them, when the front flip plate assembly 6, the middle seat plate assembly 7, and the rear flip plate assembly 8 are in a horizontal state, a bed structure is formed; when the front flip plate assembly 6 is in a horizontal state, the middle seat plate assembly 7 moves between the toilet body 5 and the front flip plate assembly 6, and the rear flip plate assembly 8 is in a horizontal state, a toilet structure is formed; when the front flip plate assembly 6 is in a horizontal state, the middle seat plate assembly 7 moves between the toilet body 5 and the front flip plate assembly 6, and the rear flip plate assembly 8 is in an inward flip state, a bathtub structure is formed; when the front flip plate assembly 6 is in an outward flip state, the middle seat plate assembly 7 moves between the toilet body 5 and the front flip plate assembly 6, the two split bathtub bodies 1 are separated, and the lifting wheel assembly 3 extends outside the bottom shell 2, a wheelchair structure is formed.

[0016] In the specific implementation process of the present invention, both the bathtub body 1 and the bottom shell 2 adopt a split structure, and the split midlines coincide. This design provides an infrastructure for the realization of multiple functions, enabling the flexible combination and operation of each component; the lifting wheel assembly 3 installed in one of the split bottom shells 2 can extend outside the bottom shell 2 when needed, providing a moving function for the formation of a wheelchair structure, and being stored inside the bottom shell 2 when not in use, 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: Formation of the bed structure: When the front, middle, and rear flip plate assemblies 8 are all in a horizontal state, the flip plates are spliced to form a plane, constituting the bed structure for the user to lie down and rest; Formation of the toilet structure: The front flip plate assembly 6 remains horizontal, the middle seat plate assembly 7 moves between the toilet body 5 and the front flip plate assembly 6, and the rear flip plate assembly 8 is also in a horizontal state. At this time, the user is in a suitable position above the toilet body 5, facilitating the user to use the toilet, and each flip plate cooperates to support the user's body; Formation of the bathtub structure: The front flip plate assembly 6 is horizontal, the middle seat plate assembly 7 is located between the toilet body 5 and the front flip plate assembly 6, the rear flip plate assembly 8 flips inward, and after the rear flip plate assembly 8 flips inward, it jointly encloses a relatively closed space with other parts of the bathtub body 1, cooperating with the bathtub body 1 to store water, forming a bathtub structure to meet the user's shower needs; Formation of the wheelchair structure: The front flip plate assembly 6 flips outward, the middle seat plate assembly 7 moves between the toilet body 5 and the front flip plate assembly 6, the two split bathtub bodies 1 are separated, the lifting wheel assembly 3 extends out as a moving structure, the front flip plate assembly 6 flips outward as a wheelchair backrest structure, and the separation of the split bathtub bodies 1 cooperates with the lifting wheel assembly 3 to enable the whole to have the moving function of a wheelchair.

[0017] For the above solution, refer to the attached Figure 1 and the attached Figure 2As shown, electromagnetic plates 11 are provided on the opposite faces of the two split bathtub bodies 1 so that the two split bathtub bodies 1 are fixed by electromagnetic adsorption; in this solution, the electromagnetic plates 11 provide a convenient and reliable way for the connection of the split bathtub bodies 1. When it is necessary to combine the bathtub bodies 1 into a complete bathtub structure for showering, just power on the electromagnetic plates 11, and the fixed connection of the two split bathtub bodies 1 can be quickly achieved, forming a stable water storage container. And when it is necessary to convert the device to other functions, such as a wheelchair structure, cut off the power supply of the electromagnetic plates 11, the magnetic field disappears, the adsorption force between the two split bathtub bodies 1 is released, and they can be easily separated to achieve the conversion between different functional structures, fully reflecting the synergistic advantages of the split design and the electromagnetic connection method.

[0018] Among them, for the connection between the two split bathtub bodies 1, in other solutions, four funnels are installed on the opposite faces of the two split bathtub bodies 1. Each funnel is provided with internal threads, and gears are provided on the outer edges of the funnels. Each of the four gears is connected to a motor so that the motors operate to make the funnels dock.

[0019] In addition, considering the sealing effect between the two split bathtub bodies 1, for this reason, refer to the appendix Figure 4 As shown, rubber strips 12 are provided on the opposite faces of the two split bathtub bodies 1, and the rubber strips 12 are inside the electromagnetic plates 11 so that when the two split bathtub bodies 1 are connected, they are first sealed by the sealing strips and then adsorbed and fixed by the electromagnetic plates 11; in the solution, when the two split bathtub bodies 1 start to dock, since the rubber strips 12 are inside the electromagnetic plates 11, they will come into contact and be squeezed first. Under the action of pressure, they can quickly fill the fine gaps between the opposite faces of the split bathtub bodies 1 and initially achieve the sealing effect by their own deformation. After the rubber strips 12 complete the sealing action, the electromagnetic plates 11 are powered on and started. The strong adsorption force generated by the electromagnetic plates 11 not only firmly fixes the bathtub bodies 1, but also additionally exerts a continuous and uniform lateral pressure on the rubber strips 12. This pressure makes the contact surface between the rubber strips 12 and the bathtub bodies 1 closer, further strengthening the sealing effect and ensuring the sealing performance doubly.

[0020] For the above solution, refer to the appendix Figure 1As shown, the lifting wheel assembly 3 includes a first telescopic cylinder 31. There are multiple groups of the first telescopic cylinders 31, which are vertically arranged in one of the split bottom shells 2. The telescopic ends of the multiple groups of the first telescopic cylinders 31 are commonly connected to a mounting plate 32, and four wheel bodies 33 are mounted on the mounting plate 32. In the solution, when the first telescopic cylinder 31 pushes the mounting plate 32 out of the bottom shell 2, the wheel bodies 33 will touch the ground accordingly. The four wheel bodies 33 are reasonably arranged to form the moving part of the wheelchair structure. And during the implementation process, the wheel bodies can adopt the power wheels in the prior art. The power wheels are electrically connected to a control handle, and the power wheels can be made to perform actions through the control handle. This method is a commonly used prior art, and the present invention will not elaborate on it too much.

[0021] For the above solution, referring to the attached Figure 1 As shown, the front flip plate assembly 6 includes a front plate 61. The tail end of the front plate 61 is rotatably connected in one of the split bathtub bodies 1, and it is hinged to the telescopic end of a second telescopic cylinder 62 hinged in one of the split bathtub bodies 1. In the solution, the front plate 61 has a rotatable degree of freedom. When the second telescopic cylinder 62 starts to work, according to its internal driving principle (such as hydraulic, pneumatic or electric), the second telescopic cylinder 62 starts to expand and contract. At this time, the front plate 61 will receive an upward acting force from the second telescopic cylinder 62, and finally the front plate 61 will rotate upward around the tail end. On the contrary, when the second telescopic cylinder 62 retracts, it will rotate downward and fall back to the initial position. By the expansion and contraction of the second telescopic cylinder 62, the front plate 61 can realize angle flipping to adapt to various functional states of the device, such as the bed structure, the toilet structure, the bathtub body 1 and the wheelchair structure. For example, when the device is in the bed structure, the second telescopic cylinder 62 is adjusted to an appropriate length to make the front plate 61 in a stable horizontal state. When switching to the wheelchair structure, the front plate 61 needs to rotate upward by a certain angle to form a backrest structure.

[0022] For the above solution, referring to the attached Figure 1 and the attached Figure 3As shown in the figure, the middle seat board assembly 7 includes a third telescopic cylinder 71. The third telescopic cylinder 71 is horizontally arranged in one of the split bathtub bodies 1, and its telescopic end is connected to a fixed seat 72. A fourth telescopic cylinder 73 is vertically arranged on the fixed seat 72. The fourth telescopic cylinder 73 is connected to a middle board 74. An opening 741 is provided on the middle board 74. When the middle board 74 moves above the toilet body 5, the opening 741 is coaxial with the inlet of the toilet body 5. A fifth telescopic cylinder 75 is arranged in cooperation with the position of the opening 741. The fifth telescopic cylinder 75 is vertically arranged in the other split bathtub body 1. The telescopic end of the fifth telescopic cylinder 75 is horizontally provided with a sixth telescopic cylinder 76. The sixth telescopic cylinder 76 is connected to a shielding board 77 for shielding the opening 741, and a filling board 78 for inserting into the opening 741 is provided on the shielding board 77. In the solution, the third telescopic cylinder 71 is horizontally installed in one of the split bathtub bodies 1. It is the starting power source for adjusting the position of the middle seat board assembly 7. When the third telescopic cylinder 71 extends, the middle board 74 can be on the same horizontal plane as the front board 61. When the third telescopic cylinder 71 contracts, the middle board 74 moves downward. Then, in cooperation with the contraction action of the fourth telescopic cylinder 73, the middle board 74 can be moved between the toilet body 5 and the front board 61, and the opening 741 is directly above the inlet of the toilet body 5, ensuring that when the user uses the sitting toilet function, the excrement can smoothly enter the toilet body 5. At the same time, the fifth telescopic cylinder 75 retracts, driving the shielding board 77 to descend, causing the filling board 78 to disengage from the opening 741, and the sixth telescopic cylinder 76 retracts, moving the shielding board 77 away, exposing the opening 741, and cooperating with the inlet of the toilet body 5 to realize the sitting toilet function.

[0023] For the above solution, referring to the attached Figure 1 As shown in the figure, the rear flip - board assembly 8 includes a rear board 81. The tail end of the rear board 81 is rotatably connected in the other split bathtub body 1, and it is hinged to the telescopic end of a seventh telescopic cylinder 82 hinged in the other split bathtub body 1. In the solution, the rear board 81 has a rotatable degree of freedom. When the seventh telescopic cylinder 82 starts to work, according to its internal driving principle (such as hydraulic, pneumatic or electric), the seventh telescopic cylinder 82 begins to extend. At this time, the rear board 81 will receive an upward acting force from the seventh telescopic cylinder 82, and finally the rear board 81 remains in a horizontal state. On the contrary, when the seventh telescopic cylinder 82 retracts, the rear board 81 immediately flips downward. By the telescoping of the seventh telescopic cylinder 82, the rear board 81 can achieve angular flipping to adapt to various functional states of the device in the bed structure, toilet structure, bathtub body 1 and wheelchair structure, etc. For example, when the device is in the bed structure, the seventh telescopic cylinder 82 is adjusted to an appropriate length to make the front board 61 stably in a horizontal state, and the rear board 81 flips onto the inclined platform 4 to form a foot - rest structure.
