Description

Technical Field

[0001] This utility model relates to the field of nursing bed technology, and in particular to a nursing bed for RV travel and elderly care. Background Technology

[0002] A nursing bed is a specialized device that provides nursing support for people with limited mobility. It typically consists of a bed frame, adjustment mechanism, and protective components. With the rise of the travel-based senior living model, RVs, as mobile travel vehicles, have an increasing demand for suitable nursing equipment to provide convenient nursing support for the elderly during their travels, ensuring their comfort and safety.

[0003] Currently, in RV travel and retirement scenarios, traditional home care beds or simple camp beds are commonly used for elderly care. However, traditional home care beds are difficult to fit into the limited interior space of RVs, are inconvenient to store, and occupy a lot of travel and activity space. In addition, the adjustment mechanisms of traditional care beds are often not suitable for the bumpy environment during RV travel, resulting in poor stability. Simple camp beds, on the other hand, lack the necessary nursing adjustment functions, cannot meet the nursing needs of the elderly such as adjusting their body position, and are not safe enough. Therefore, traditional nursing equipment is difficult to adapt to the usage needs of RV travel and retirement scenarios and needs to be improved. Utility Model Content

[0004] The present invention aims to provide a nursing bed for RV travel and elderly care, in order to solve the problems mentioned in the background art that the traditional devices are not well adapted to RV space, have insufficient nursing adjustment functions and poor stability.

A rotating drum is fixed to the end of the connecting rod away from the first motor. A connecting block is fixed to the side of the bed board away from the L-plate by screws. The top of the pull rope is fixed inside the rotating drum, and the bottom is fixed inside the connecting block. The pull rope is retracted and extended by driving the rotating drum to rotate through the first motor, thereby driving the bed board to be retracted or extended.

[0008] In some embodiments, a first baffle is provided above the first motor, and a second baffle is connected to both ends by screws; the first baffle is fixed to the L plate by screws, and the connecting rod and the rotating drum are both housed in the second baffle to protect the recycling component.

[0009] In some embodiments, the side of the bed board near the L-board is connected to the L-board via multiple sets of rotating blocks; one side of the rotating block is fixed to the L-board via multiple sets of screws, and the other side is rotatably connected to the bed board via a rotating shaft, thereby realizing rotational guidance when the bed board is stored or unfolded.

[0010] In some embodiments, the bed board is connected to the rotating plate via a rotating block; one end of the rotating block is fixed to the bed board by multiple sets of screws, and the other end is rotatably connected to the rotating plate via the rotating shaft, thereby cooperating with the hydraulic rod to realize the angle adjustment of the rotating plate.

[0011] In some embodiments, a retainer is fixed to the bottom of the rotating plate by screws. The retainer has a semi-open structure with its opening facing the L-plate, which facilitates the locking of the rotating plate after it is lowered. A protective shell is provided below the retainer. The bottom of the protective shell is fixed to the L-plate by multiple sets of screws, and a slot is provided on the top to accommodate the hydraulic rod and provide protection.

[0012] In some embodiments, the length of the slot is greater than the height of the hydraulic rod shaft after retraction; the top shaft of the hydraulic rod passes through the slot and is snapped into the sleeve, and the bottom is fixed to the L-plate and rotatably connected to the L-plate through a rotating shaft; a handle is sleeved on the hydraulic rod, the handle is located outside the L-plate and its length is less than the height of the L-plate, so as to facilitate manual retraction of the hydraulic rod.

[0013] In some embodiments, a base plate is provided below the L-plate, and the L-plate is connected to the base plate by multiple sets of connecting rods; the top of the connecting rod extends through the L-plate into the protective shell, and a spring is sleeved on the connecting rod, the spring being used to compensate for the stability of the base plate during movement; multiple sets of universal wheels are fixed to the bottom of the L-plate by screws, the universal wheels passing through the base plate, and cooperating with the vertical expansion and contraction of the base plate to achieve retraction and extension.

[0014] In some embodiments, an expansion plate is provided between the L-plate and the base plate, and a threaded rod is internally threaded onto the expansion plate; a second motor and a limiting plate are respectively connected to both ends of the threaded rod; the second motor is fixed to the base plate by a mounting base and multiple sets of screws, and the limiting plate is fixed to the base plate by screws; the threaded rod is driven to rotate by the second motor, thereby causing the expansion plate to extend and retract, thus realizing the vertical expansion of the base plate and achieving the function of deploying and retracting the casters.

[0015] In some embodiments, two sets of limiting strips are provided at both ends of the L-plate. The ends of two adjacent sets of limiting strips that are close to each other are connected by limiting blocks and rotated by bearings. The ends that are far apart from each other are connected to the L-plate and the bed board by rotating shafts, which is used to improve the stability of the bed board after it is unfolded. Multiple sets of mounting holes are provided on the L-plate.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] In this invention, when providing elderly care in a motorhome, the bed board is retracted by a recyclable component. A first motor drives a rotating drum to retract the pull rope, causing the bed board to fold around the rotating block and into the L-shaped plate within the motorhome space. During the retraction process, the limiting strip folds simultaneously without taking up additional space. When support is needed, the first motor releases the pull rope to unfold the bed board. Then, a hydraulic rod drives the rotating plate to rotate and adjust the angle. During the angle adjustment, a clamp secures the output end of the hydraulic rod. Through these steps, the bed board can be retracted, unfolded, and the angle of the rotating plate adjusted to adapt to the limited space of the motorhome and meet the group care needs of the elderly.

[0018] In this invention, springs are fitted onto the connecting rods to compensate for the stability of the base plate's movement, and the cooperation of limiting strips and limiting blocks enhances the stability of the bed board after it is unfolded. Additionally, retractable casters are used to adapt to RV movement scenarios, ensuring the stability and reliability of the nursing bed during RV travel and solving the problem of poor stability of traditional nursing equipment in RV environments. Furthermore, the mounting holes on the L-plate facilitate the installation of nursing tools, further improving the convenience of nursing care and offering superior adaptability and practicality compared to traditional nursing equipment.

[0034] This embodiment discloses a nursing bed for RV travel and elderly care. The core structure includes an L-plate 11, a bed board 12, a rotating plate 13, a hydraulic rod 14, a retraction component, and a base plate 31, etc. The connection relationship and specific implementation details of each component are as follows:

[0035] In some embodiments, the L-plate 11 serves as the overall support base, with a foldable bed board 12 mounted on one side. The bed board 12 and the L-plate 11 are folded and unfolded via a retraction assembly. The retraction assembly includes a first motor 21, a pull rope 22, a connecting rod 23, a rotating drum 24, and a connecting block 25. The first motor 21 is fixed to the L-plate 11 with multiple sets of screws. The first motor 21 is a dual-head motor, and connecting rods 23 are fixed to both ends of the first motor 21. The rotating drum 24 is fixed to the end of the connecting rod 23 away from the first motor 21. The connecting block 25 is fixed to the side of the bed board 12 away from the L-plate 11 with screws. The top of the pull rope 22 is fixed inside the rotating drum 24, and the bottom is fixed inside the connecting block 25. In specific implementation, the first motor 21 drives the rotating drum 24 to rotate, thereby retracting and extending the pull rope 22, which in turn drives the bed board 12 to fold or unfold, thus saving interior space in the RV.

[0036] Specifically, the L-shaped board 11 is made of aluminum alloy and features an L-shaped structure, ensuring both structural strength and lightweight design to meet the weight restrictions of RVs. The first motor 21 can be a dual-head motor with a dual-axis output structure that allows for simultaneous retraction and extension of the pull ropes 22 on both sides, preventing tilting or jamming during the folding and unfolding of the bed board 12. The first motor 21 is evenly fixed to the L-shaped board 11 with multiple sets of screws to ensure stability and prevent loosening due to RV travel bumps. The connecting rod 23 is made of stainless steel and is fixed to the shaft end of the first motor 21 using a key connection, providing high connection strength and easy disassembly. The inner wall of the rotating drum 24 has an annular groove, and the top of the pull rope 22 is fixed in the groove with a buckle to prevent slippage during retraction and extension. The connecting block 25 is made of engineering plastic and is fixed to the end of the bed board 12 by multiple sets of self-tapping screws. It has a threaded hole inside that matches the pull rope 22. The bottom of the pull rope 22 is fixed to the threaded hole by a crimping method, ensuring that the pull rope 22 can stably drive the bed board 12. The pull rope 22 is made of stainless steel wire rope, which has tensile strength and can bear part of the weight of the bed board 12 and the user, meeting the weight-bearing requirements of elderly care scenarios.

[0037] In some embodiments, a first baffle 26 is provided above the first motor 21, and a second baffle 27 is connected to both ends by screws. The first baffle 26 is fixed to the L plate 11 by screws, and the connecting rod 23 and the rotating drum 24 are both housed in the second baffle 27. The cooperation of the first baffle 26 and the second baffle 27 protects the recycling component and reduces the impact of dust and debris on the operation of the component during the RV's operation.

[0038] Specifically, both the first baffle 26 and the second baffle 27 are made of ABS engineering plastic, which is lightweight, impact-resistant, waterproof, and dustproof, making them suitable for the driving environment of the RV. The first baffle 26 is fixed to the L-plate 11 with multiple sets of screws, covering the first motor 21 and preventing debris and liquids falling from above from entering the motor. The second baffle 27 is fixed to both ends of the first motor 21 with multiple sets of screws, forming a protective cavity that completely covers the connecting rod 23 and the rotating drum 24. A gap is reserved between the protective cavity and the connecting rod 23 and the rotating drum 24, which does not affect the movement of the components but also provides protection, preventing the components from colliding with the baffle and being damaged when the RV brakes suddenly or bumps.

[0039] In some embodiments, the side of the bed board 12 closest to the L-plate 11 is connected to the L-plate 11 via multiple sets of rotating blocks 15. One side of the rotating block 15 is fixed to the L-plate 11 by multiple sets of screws, and the other side is rotatably connected to the bed board 12 via a rotating shaft. This provides stable rotation guidance for the bed board 12 when it is folded or unfolded, ensuring smooth folding and folding. Simultaneously, the bed board 12 is connected to a rotating plate 13 via the rotating blocks 15. One end of the rotating block 15 is fixed to the bed board 12 by multiple sets of screws, and the other end is rotatably connected to the rotating plate 13 via a rotating shaft. This, in conjunction with the hydraulic rod 14, allows for angle adjustment of the rotating plate 13 to accommodate different patient positions.

[0040] Specifically, the rotating block 15 is made of stainless steel and consists of a fixed end and a rotating end. The fixed end is a flat plate with multiple sets of screw holes, which are used to fasten it to the L-plate 11 and the bed board 12. The rotating end is a U-shaped structure with a copper sleeve embedded inside. The rotating shaft passes through the copper sleeve and is rotatably connected to the bed board 12 and the rotating plate 13. The copper sleeve reduces the coefficient of friction during rotation, reduces noise, and improves rotational stability, preventing jamming after long-term use. Both the bed board 12 and the rotating plate 13 are made of multi-layer solid wood composite board with a waterproof and stain-resistant PVC film on the surface for easy cleaning and maintenance. A gap is reserved at the connection between the bed board 12 and the rotating plate 13 to prevent interference between the rotating plate 13 and the bed board 12 when adjusting the angle. Multiple sets of rotating blocks 15 are evenly distributed at the connection between the bed board 12 and the L-plate 11, and at the connection between the bed board 12 and the rotating plate 13, ensuring uniform force distribution and improving the overall structural stability.

[0041] In some embodiments, the bottom of the rotating plate 13 is fixed with a sleeve 16 by screws. The sleeve 16 has a semi-open structure with the opening facing the L plate 11. A protective shell 17 is provided below the sleeve 16. The bottom of the protective shell 17 is fixed to the L plate 11 by multiple sets of screws, and a slot is provided on the top for accommodating the hydraulic rod 14. The top shaft end of the hydraulic rod 14 is rotatably connected to a connector head via a rotating shaft. A reset sleeve is fitted onto the connector head, and the bottom screw of the reset sleeve is fixed to the hydraulic rod 14. The connector head passes through a slot and is snapped into the sleeve 16. The bottom of the hydraulic rod 14 is snapped and fixed to the L plate 11 and is rotatably connected to the L plate 11 via a rotating shaft. The hydraulic rod 14 can be a conventional electric hydraulic rod, which is a common standard component known in the art. It can be directly powered by an external vehicle power supply, which is a conventional technical means in the industry. Those skilled in the art can understand its power supply method based on common knowledge. In specific implementation, the sleeve 16 snaps and fixes the connector head of the hydraulic rod 14. The connector head rotates synchronously during the adjustment of the rotating plate 13. The sleeve 16 ensures the stability of the connector head when the rotating plate 13 is adjusted to the target angle, reducing the angular deviation of the rotating plate 13. After the reset sleeve is retracted at the shaft end of the hydraulic rod 14, it drives the connector head to reset, ensuring that the sleeve 16 can stably snap into the connector head when the bed plate 12 is lowered. In addition, a handle 18 is fitted onto the hydraulic rod 14. The handle 18 is located outside the L-plate 11 and its length is less than the height of the L-plate 11, facilitating manual retraction of the hydraulic rod 14. The length of the slot at the top of the protective shell 17 is greater than the height of the retracted shaft end of the hydraulic rod 14, providing sufficient travel for the retraction of the hydraulic rod 14 and preventing jamming. After the hydraulic rod 14 is retracted at its telescopic end, the user can push the handle 18 to make the hydraulic rod 14 disengage from the locking hole and rotate towards the protective shell 17 until the hydraulic rod 14 passes through the slot at the top of the protective shell 17 and is retracted into the protective shell 17.

[0042] Specifically, the ferrule 16 is made of cast aluminum, and its semi-open structure has an opening size that matches the outer dimensions of the connector. A guide chamfer is provided at the opening to facilitate connector insertion. A rubber pad is lined inside the ferrule 16 to reduce collisions between the connector and the ferrule 16, while increasing friction and improving locking stability. The protective shell 17 is a sheet metal stamping part made of stainless steel with a powder-coated surface, providing excellent rust and corrosion resistance. The internal dimensions of the protective shell 17 are adapted to the outer dimensions of the hydraulic rod 14, enclosing the main body of the hydraulic rod 14 and reducing the intrusion of dust and debris into the hydraulic rod 14, thus minimizing its telescopic function. The connector is made of stainless steel and has a cylindrical structure. One end is rotatably connected to the shaft of the hydraulic rod 14 via a rotating shaft, while the other end is cylindrical, adaptable to the adjustment requirements of the rotating plate 13 at different angles. The reset sleeve is made of rubber and has a cylindrical structure. It is fitted onto the connection between the connector and the shaft end of the hydraulic rod 14. When the shaft end of the hydraulic rod 14 is retracted, it can drive the connector to reset, so that the cylindrical end of the connector faces the opening direction of the retaining sleeve 16, ensuring that the retaining sleeve 16 can be inserted. The hydraulic rod 14 can be angled to accommodate different nursing positions such as sitting and semi-reclining. The handle 18 is made of engineering plastic with a non-slip texture, which is convenient for manual operation. Its length is smaller than the height of the L-plate 11 to avoid excessive protrusion on the outside of the L-plate 11 and causing bumps. After the extension end of the hydraulic rod 14 is retracted, the user can pull the handle 18 to rotate the hydraulic rod 14 in the direction of the slot length, thereby retracting the hydraulic rod 14 into the protective shell 17.

[0043] In some embodiments, a base plate 31 is provided below the L-plate 11. The L-plate 11 is connected to the base plate 31 by multiple sets of fixing rods 32. The top of the fixing rods 32 extends through the L-plate 11 into the protective shell 17, and a spring is sleeved on the fixing rod 32 to compensate for the stability of the base plate 31 during movement. Multiple sets of casters 33 are fixed to the bottom of the L-plate 11 by screws. The casters 33 are inserted into the base plate 31 and are used to expand and contract with the vertical expansion of the base plate 31, facilitating the movement and fixation of the nursing bed.

[0044] Specifically, the base plate 31 is made of steel plate with a rectangular structure, possessing excellent load-bearing capacity. It can distribute the overall weight of the nursing bed and adapt to the load-bearing limitations of the RV floor. The fixing rod 32 is made of stainless steel with a cylindrical structure and a stop at the top. A spring is sleeved between the stop of the fixing rod 32 and the L-plate 11. The spring is a compression spring, which can elastically deform to compensate for the vertical movement of the base plate 31. Multiple sets of fixing rods 32 are evenly arranged to ensure the connection stability between the L-plate 11 and the base plate 31. The casters 33 are fixed to the bottom of the L-plate 11 with multiple sets of screws. The base plate 31 has clearance holes corresponding to the positions of the casters 33. The diameter of the clearance holes is larger than the diameter of the casters 33 to ensure that the base plate 31 does not interfere with the casters 33 when moving up and down. When the base plate 31 is lowered, the casters 33 are exposed in the clearance holes, allowing the nursing bed to be moved. When the base plate 31 is raised, the casters 33 are retracted into the clearance holes, and the base plate 31 is fixed to the ground, improving the stability of the bed.

[0045] In some embodiments, an expansion plate 34 is provided between the L-plate 11 and the base plate 31. The top of the expansion plate 34 is provided with a guide slope. A threaded rod 35 is internally threaded to the expansion plate 34. The two ends of the threaded rod 35 are respectively connected to a second motor 36 and a limiting plate 37. The second motor 36 is fixed to the base plate 31 by a mounting base and multiple sets of screws. The bottom of the L-plate 11 is provided with a slot corresponding to the expansion plate 34 and the threaded rod 35. The limiting plate 37 is fixed to the base plate 31 by screws. In specific implementation, the second motor 36 drives the threaded rod 35 to rotate, causing the expansion plate 34 to move laterally along the threaded rod 35. The inclined surface of the expansion plate 34 abuts against the inclined surface of the bottom groove of the base plate 31. Under the vertical guiding constraint of the fixed rod 32, the lateral linear motion of the expansion plate 34 is converted into the vertical lifting motion of the base plate 31 by utilizing the component force effect of the inclined surface. This drives the base plate 31 to move up and down, so that the caster wheel 33 is retracted into the base plate 31 or exposed outside the base plate 31, realizing the retraction and extension function of the caster wheel 33. The limiting plate 37 can limit the movement stroke of the expansion plate 34 to prevent the expansion plate 34 from excessively extending or retracting and causing structural damage. When the expansion plate 34 moves toward the limiting plate 37, the base plate 31 moves downward and the caster wheel 33 is retracted into the base plate 31, and vice versa.

[0046] Specifically, the expansion plate 34 is made of aluminum alloy and has an internal threaded hole that matches the threaded rod 35, ensuring smooth transmission with the threaded rod 35. The threaded rod 35 is a threaded screw that can stably drive the expansion plate 34 to extend and retract. The threaded rod 35 is connected to the output shaft of the second motor 36, which is fixed to the base plate 31 by a mounting bracket. The mounting bracket is connected to the base plate 31 by multiple sets of screws to ensure fixation. A slot is opened at the bottom of the L-plate 11, and the size of the slot is interference-fitted with the outer dimensions of the expansion plate 34. When the expansion plate 34 is inserted into the slot, the L-plate 11 and the base plate 31 can be fitted and fixed together, improving the stability of the bed. When the expansion plate 34 is disengaged from the slot, the base plate 31 descends, and the universal wheels 33 are exposed through clearance holes. The limiting plate 37 has a guide hole that matches the threaded rod 35. A copper sleeve is embedded in the guide hole, which can support and guide the end of the threaded rod 35, while limiting the axial displacement of the threaded rod 35, so as to prevent the expansion plate 34 from excessively extending and retracting beyond its stroke range, which would cause structural damage.

[0047] In some embodiments, two sets of limiting strips 41 are respectively provided at both ends of the L-plate 11. The ends of two adjacent sets of limiting strips 41 that are close to each other are connected by limiting blocks 42 and rotated by bearings. The ends that are far apart from each other are respectively connected to the L-plate 11 and the bed board 12 by rotating shafts, which is used to improve the stability of the bed board 12 after it is unfolded. The end of the limiting block 42 near the limiting strip 41 is integrally formed with a protrusion, and the limiting strip 41 is correspondingly provided with a groove. The groove is provided with a slot. In specific implementation, when the bed board 12 is unfolded to a horizontal state, the user can rotate the limiting block 42 so that the protrusion is locked into the groove. The limiting strip 41 is locked by the cooperation of the protrusion and the groove, which further enhances the stability of the bed board 12 after it is unfolded and prevents the limiting strip 41 from rotating and shifting during the movement of the RV. When the bed board 12 needs to be stored, the limiting block 42 is rotated in the opposite direction so that the protrusion is disengaged from the groove, and the locking is released. The limiting strip 41 is folded synchronously with the bed board 12. In addition, multiple sets of mounting holes are provided on the L-plate 11 to assist in the installation of the L-plate 11 and nursing equipment such as IV stands and guardrails, further improving the convenience of nursing care. A folding guardrail is fixed with screws on the side of the bed board 12 away from the L-plate 11 to prevent the user from falling accidentally.

[0048] Specifically, the limiting strip 41 is made of stainless steel, possessing excellent bending strength, and provides lateral support for the unfolded bed board 12. Both ends of the limiting strip 41 are equipped with connecting ears, which are rotatably connected to the L-plate 11, bed board 12, and limiting block 42 via a rotating shaft. Bearings are embedded between the rotating shaft and the connecting ears to improve rotational flexibility. The limiting block 42 is made of aluminum alloy, with an integrally formed cylindrical protrusion. The size and clearance between the protrusion and the groove ensure a snug fit during locking. The slots on the groove serve as a guide structure, facilitating the protrusion's insertion and disengagement. A set of limiting strips 41 and limiting blocks 42 are provided at each end of the L-plate 11, forming a symmetrical limiting structure that ensures even force distribution on both sides of the bed board 12 after unfolding, improving overall stability. The mounting holes are through holes, evenly distributed on the side of the L-plate 11, with multiple sets. Different types of nursing tools can be installed using bolts. For example, the infusion stand adopts a telescopic structure and is fixed in the mounting hole by locking bolts to accommodate the nursing needs of users of different heights. The folding guardrail is made of aluminum alloy and is connected to the bed board 12 by screws. It can be flipped up and locked or folded down for storage, which can prevent users from falling accidentally. After folding, it does not take up extra space and is easy to store on the bed board 12.

[0049] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
