Description

Technical Field

[0001] This utility model relates to the field of furniture technology, and in particular to a liftable electric bed. Background Technology

[0002] With the development of society and the economy, people's income levels are constantly rising, and their demands for quality of life are also gradually increasing. People are beginning to pay attention to high-quality products and services in order to pursue a higher quality of life; compared with traditional beds, electric beds can be adjusted to different positions according to needs to adapt to different users, providing users with a better user experience, and are being favored by more and more people.

[0003] Existing electric beds use a motor to directly lift the bed board vertically to achieve the lifting function. This lifting method has the following drawbacks: 1. The lifting range depends on the motor's stroke, and the lifting height is limited; 2. When using multiple motors to lift multiple positions, it is difficult to synchronize the lifting strokes, causing the bed board to tilt; 3. Finally, in the event of motor failure, this lifting method can easily cause the bed board to fall directly, which is dangerous. Utility Model Content

[0004] In view of the shortcomings of the prior art described above, the technical problem to be solved by this utility model is to provide a lifting electric bed that solves the problems of limited lifting stroke, difficulty in synchronization, and certain failure risk of existing lifting electric beds.

[0005] To solve the above-mentioned technical problems, this utility model provides a lifting electric bed, comprising:

[0006] The base frame and lifting assembly, wherein the lifting assembly includes a front linkage bracket, a rear linkage bracket, and a transmission rod connecting the front linkage bracket and the rear linkage bracket. The front linkage bracket includes a front support rod and a front push rod, one end of the front support rod and the front push rod being hinged to the front part of the base frame, and the other end of the front push rod being hinged to the middle part of the front support rod. The rear linkage bracket includes a rear support rod and a rear push rod, one end of the rear support rod and the rear push rod being hinged to the rear part of the base frame, and the other end of the rear push rod being hinged to the middle part of the rear support rod.

[0007] The system includes a support frame and a lifting drive unit mounted on the support frame. The support frame is positioned above the base frame. One end of the front support rod is hinged to the front of the support frame, and the other end of the rear support rod is hinged to the rear of the support frame. The lifting drive unit is connected to the transmission rod. The lifting drive unit drives the transmission rod to rotate synchronously, causing the front and rear support rods on the front and rear connecting rod brackets to rotate. The front and rear push rods provide support for the front and rear support rods, respectively. By rotating the front and rear support rods at different angles, the support frame is raised and lowered.

[0008] As a more preferred embodiment, the lifting assembly includes two sets of front linkage brackets and a rear linkage bracket, which are respectively hinged to both sides of the base frame. The advantage is that the two sets of front and rear linkage brackets are symmetrically arranged on both sides of the base frame, ensuring that the force on the support frame is evenly distributed on both sides, avoiding structural deformation caused by concentrated force on one side. During lifting, the brackets on both sides move synchronously, further improving the stability of the support frame's lifting. Even if the bed surface is unevenly loaded, it can remain stable, reducing the risk of tipping over and enhancing safety.

[0009] As a more preferred embodiment, the lifting electric bed further includes a front drive beam and a rear drive beam. The two ends of the front drive beam are respectively fixed to the front support rods of the two sets of front connecting rod brackets, and the two ends of the rear drive beam are respectively fixed to the rear support rods of the two sets of rear connecting rod brackets. The two ends of the drive rod are respectively hinged to the front drive beam and the rear drive beam. Its advantages lie in that the front and rear drive beams connect the front and rear support rods on both sides, forming a lateral linkage structure, ensuring that the support rods on both sides rotate synchronously, avoiding tilting or jamming of the support frame due to asynchronous movement of the two side brackets. The drive beams also enhance the overall integrity of the two side brackets, reducing swaying during lifting and lowering, and improving the overall structural stability of the bed, especially suitable for supporting large-size bed surfaces.

[0010] As a more preferred embodiment, the lifting assembly further includes a front reinforcing structure, which comprises a front reinforcing beam and two front reinforcing rods. The two ends of the front reinforcing beam are respectively fixed to one end of the front support rod of each of the two sets of front connecting rod brackets. One end of each front reinforcing rod is fixed to the front reinforcing beam, and the other end is fixed to the front transmission beam. The advantages are that the two transmission rods are connected by a connecting beam, allowing the driving force of the lifting drive component to be evenly transmitted to both transmission rods, avoiding damage from overload on a single transmission rod and extending the service life of the drive structure. The integrated drive design of the connecting beam ensures coordinated movement of the front and rear connecting rod brackets, preventing a situation where the front side lifts faster than the rear side, further optimizing lifting stability and improving user experience.

[0011] As a more preferred embodiment, the lifting assembly further includes a rear reinforcing structure, which comprises a rear reinforcing beam and two rear reinforcing rods. The two ends of the rear reinforcing beam are respectively fixed to one end of the rear support rod of each of the two sets of rear connecting rod supports. One end of each rear reinforcing rod is fixed to the rear reinforcing beam, and the other end is fixed to the rear transmission beam. The beneficial effect is that the front reinforcing beam and the front reinforcing rods form a front reinforcing structure, connecting the front support rod and the front transmission beam into a whole, enhancing the deformation resistance of the front connecting rod support. Especially when the support frame is raised and the front side is under greater stress, the reinforcing structure can distribute the stress on the front support rod, preventing it from bending due to long-term load-bearing, improving the reliability of the front support, and extending the service life of the bed.

[0012] As a more preferred embodiment, the lifting assembly includes two transmission rods and a connecting beam. The two transmission rods are connected by the connecting beam, and the lifting drive is connected to the connecting beam. The connecting beam drives the transmission rods, thereby causing the front and rear connecting rod supports to rotate synchronously. Its advantages are that the rear reinforcement structure and the front reinforcement structure form symmetrical reinforcement, balancing the structural strength of the front and rear sides of the bed and preventing the bed foot from sinking due to weak rear support. The rear reinforcement beam and rear reinforcement rod can distribute the force on the rear support rod, especially in scenarios where the bed foot bears weight when the user is lying down, preventing deformation of the rear support rod, ensuring the bed surface remains flat, and improving user comfort and structural stability.

[0013] As a more preferred embodiment, the lifting electric bed further includes a bed board assembly and a front drive assembly. The bed board assembly includes a seat plate disposed in the middle of the support frame and a back plate hinged to the front side of the seat plate. The front drive assembly is disposed on the front side of the support frame and drives the back plate to rotate along the hinged end with the seat plate. The advantages are that the back plate and seat plate are hinged, and with the cooperation of the front drive assembly, the tilt angle of the back plate can be flexibly adjusted, which can meet the user's needs for various postures such as sitting up to read, semi-reclining to rest, and lying flat to sleep, without the need for additional backrests, thus improving the convenience and comfort of use. The drive assembly is integrated into the support frame, without occupying additional space under the bed, and while adapting to the lifting function, it also increases the multi-functionality of the bed.

[0014] As a more preferred embodiment, the bed board assembly further includes a thigh board and a calf board. One end of the thigh board and the calf board are hinged together, and the other end of the thigh board is hinged to the rear side of the seat board. The other end of the calf board is connected to the support frame via a connecting rod, and both ends of the connecting rod are hinged to the calf board and the support frame, respectively. The lifting electric bed also includes a rear drive assembly, which drives the thigh board to rotate along the hinged end with the seat board, thereby driving the calf board to rotate. The advantages are that the hinged design of the thigh board and the calf board, combined with the rear drive assembly, allows for leg lifting and bending adjustment, helping users relax leg muscles and relieve fatigue from prolonged sitting, making it especially suitable for the elderly and postoperative recovery patients. The calf board is linked to the support frame via the connecting rod, ensuring a smooth leg adjustment process without the risk of jamming or sudden drop, thus balancing functionality and safety.

[0015] As a more preferred embodiment, the lifting electric bed also includes a surrounding frame assembly. The surrounding frame assembly includes a front panel, a rear panel, and two side panels connecting the front panel and the rear panel. The front panel, rear panel, and two side panels are respectively fixed to the perimeter of the support frame and rise and fall synchronously with the support frame. Its advantages are that the surrounding frame assembly, encircling the support frame, protects the internal structures such as the bed board assembly and the lifting assembly, preventing dust and foreign objects from entering the gaps and affecting mechanical operation, thus reducing maintenance frequency. The surrounding frame rises and falls synchronously with the support frame, always remaining flush with the bed surface, avoiding gaps between the lifting bed surface and the surrounding frame. This ensures a neat and uniform appearance and prevents users' clothing or hands from being pinched by the gaps, improving safety.

[0016] As a more preferred option, the lifting electric bed also includes two guardrail assemblies, which are respectively located on both sides of the support frame. The advantage of this is that the guardrail assemblies on both sides can effectively prevent users from turning over and falling off the side of the bed while sleeping, reducing safety hazards. At the same time, the guardrails can also serve as "handrails" for users to get up, helping them to support their bodies from a lying position, making it easier to get in and out of bed, combining protection and auxiliary functions, and improving the convenience of use for special groups.

[0017] As described above, the lifting electric bed of this utility model has the following beneficial effects: The lifting electric bed of this utility model uses the lifting drive component to drive the transmission rod, which in turn drives the front support rod and the rear support rod on the front and rear connecting rod brackets to rotate synchronously. The different rotation angles of the front and rear support rods achieve the lifting of the support frame. The transmission rod ensures the synchronous rotation of the front and rear connecting rod brackets, preventing the bed from tilting. Simultaneously, the rotation of the front and rear support rods drives the lifting of the support frame, reducing the dependence of the lifting height on the stroke of the lifting drive component. Finally, the front and rear push rods provide a certain supporting force to the front and rear support rods, preventing the bed board from falling directly due to the failure of the lifting drive component. It can be seen that the lifting electric bed of this utility model solves the problems of limited lifting stroke, difficulty in synchronization, and certain failure risks existing in existing lifting electric beds.

[0064] like Figure 1 as well as Figure 2 As shown, this utility model provides a lifting electric bed, comprising:

[0065] The base frame 1 and the lifting assembly 2, wherein the lifting assembly 2 includes a front connecting rod bracket 21, a rear connecting rod bracket 22, and a transmission rod 23 connecting the front connecting rod bracket 21 and the rear connecting rod bracket 22. The front connecting rod bracket 21 includes a front support rod 211 and a front push rod 212. One end of the front support rod 211 and the front push rod 212 is hinged to the front part of the base frame 1, and the other end of the front push rod 212 is hinged to the middle part of the front support rod 211. The rear connecting rod bracket 22 includes a rear support rod 221 and a rear push rod 222. One end of the rear support rod 221 and the rear push rod 222 is hinged to the rear part of the base frame 1, and the other end of the rear push rod 222 is hinged to the middle part of the rear support rod 221.

[0066] The support frame 3 and the lifting drive 4 mounted on the support frame 3 are arranged above the base frame 1. The other end of the front support rod 211 is hinged to the front of the support frame 3, and the other end of the rear support rod 221 is hinged to the rear of the support frame 3. The lifting drive 4 is connected to the transmission rod 23. The lifting drive 4 drives the transmission rod 23 to drive the front support rod 211 and the rear support rod 221 on the front connecting rod bracket 21 and the rear connecting rod bracket 22 to rotate synchronously. The front push rod 212 and the rear push rod 222 provide support for the front support rod 211 and the rear support rod 221, respectively. The support frame 3 is raised and lowered by the different rotation angles of the front support rod 211 and the rear support rod 221.

[0067] To better illustrate the lifting electric bed of this utility model, the following specific application will be used as an example: The lifting electric bed of this utility model uses the lifting drive component 4 to drive the transmission rod 23, which in turn drives the front support rod 211 and the rear support rod 221 on the front connecting rod bracket 21 and the rear connecting rod bracket 22 to rotate synchronously. By using the different rotation angles of the front support rod 211 and the rear support rod 221, the lifting of the support frame 3 is achieved. The transmission rod 23 ensures the synchronous rotation of the front connecting rod bracket 21 and the rear connecting rod bracket 22, preventing the bed body from... The tilting mechanism is improved; simultaneously, the rotation of the front support rod 211 and the rear support rod 221 drives the support frame 3 to rise and fall, reducing the dependence of the lifting height on the stroke of the lifting drive component 4; finally, the front push rod 212 and the rear push rod 222 are set to provide a certain supporting force to the front support rod 211 and the rear support rod 221, avoiding the risk of the bed board falling directly after the lifting drive component 4 fails; it can be seen that the lifting electric bed of this utility model solves the problems of limited lifting stroke, difficulty in synchronization and certain failure risk of existing lifting electric beds.

[0068] In some possible embodiments of this utility model, such as Figure 1As shown, the lifting assembly 2 includes two sets of front connecting rod supports 21 and rear connecting rod supports 22, which are respectively hinged to both sides of the base frame 1. The beneficial effect is that the two sets of front and rear connecting rod supports 22 are symmetrically arranged on both sides of the base frame 1, so that the force on the support frame 3 is evenly distributed on both sides of the base frame 1, avoiding structural deformation caused by concentrated force on one side; during the lifting process, the supports on both sides move synchronously, further improving the stability of the lifting of the support frame 3. Even if the bed surface is unevenly loaded, it can remain stable, reduce the risk of tipping over, and enhance the safety of use.

[0069] In some possible embodiments of this utility model, such as Figure 1 As shown, the lifting electric bed also includes a front transmission beam 24 and a rear transmission beam 25. The two ends of the front transmission beam 24 are respectively fixed to the front support rods 211 of the two sets of front connecting rod brackets 21, and the two ends of the rear transmission beam 25 are respectively fixed to the rear support rods 221 of the two sets of rear connecting rod brackets 22. The two ends of the transmission rod 23 are respectively hinged to the front transmission beam 24 and the rear transmission beam 25. Its beneficial effect is that the front transmission beam 24 and the rear transmission beam 25 are respectively connected to the front support rods 211 and the rear support rods 221 on both sides, forming a transverse linkage structure, ensuring that the support rods 33 on both sides rotate synchronously, avoiding the tilting or jamming of the support frame 3 due to the asynchronous movement of the two side brackets; the transmission beam also enhances the overall integrity of the two side brackets, reduces the shaking during the lifting process, and improves the overall structural stability of the bed, especially suitable for the support needs of large-size bed surfaces.

[0070] In some possible embodiments of this utility model, such as Figure 1 As shown, the lifting assembly 2 also includes a front reinforcing structure 213, which includes a front reinforcing beam 213a and two front reinforcing rods 213b. The two ends of the front reinforcing beam 213a are respectively fixed to one end of the front support rod 211 of the two sets of front connecting rod brackets 21. One end of the front reinforcing rod 213b is fixed to the front reinforcing beam 213a, and the other end is fixed to the front transmission beam 24. Its beneficial effect is that the two transmission rods 23 are connected by a connecting beam 26, allowing the driving force of the lifting drive component 4 to be evenly transmitted to the two transmission rods 23, avoiding damage from overload on a single transmission rod 23 and extending the service life of the drive structure. The integrated drive design of the connecting beam 26 ensures that the movements of the front and rear connecting rod brackets 22 are coordinated and consistent, preventing a situation where the front side lifts faster than the rear side, further optimizing lifting stability and improving user experience.

[0071] In some possible embodiments of this utility model, such as Figure 1As shown, the lifting assembly 2 also includes a rear reinforcing structure 223, which includes a rear reinforcing beam 223a and two rear reinforcing rods 223b.

One end of the rear reinforcing rod 223b is fixed to the rear reinforcing beam 223a, and the other end is fixed to the rear transmission beam 25. Its beneficial effect is that the front reinforcing beam 213a and the front reinforcing rod 213b form a front reinforcing structure, connecting the front support rod 211 and the front transmission beam 24 into a whole, enhancing the deformation resistance of the front connecting rod bracket 21. Especially when the support frame 3 is raised and the front side is subjected to greater force, the reinforcing structure can disperse the force on the front support rod 211, prevent it from bending due to long-term load, improve the reliability of the front support, and extend the service life of the bed.

[0072] In some possible embodiments of this utility model, such as Figure 1 As shown, the lifting assembly 2 includes two transmission rods 23 and a connecting beam 26. The two transmission rods 23 are connected by the connecting beam 26. The lifting drive component 4 is connected to the connecting beam 26. The connecting beam 26 drives the transmission rods 23, thereby driving the front connecting rod bracket 21 and the rear connecting rod bracket 22 to rotate synchronously. Its beneficial effect is that the rear reinforcing structure 223 and the front reinforcing structure 213 form symmetrical reinforcement, balancing the structural strength of the front and rear sides of the bed and preventing the bed foot from sinking due to weak rear support. The rear reinforcing beam 223a and the rear reinforcing rod 223b can distribute the force on the rear support rod 221. Especially when the user is lying down and the bed foot bears weight, it can prevent the rear support rod 221 from deforming, ensuring that the bed surface always remains flat, improving the comfort and structural stability.

[0073] In some possible embodiments of this utility model, such as Figure 1 As shown, the lifting electric bed also includes a bed board assembly 5 and a front drive assembly 6. The bed board assembly 5 includes a seat plate 52 disposed in the middle of the support frame 3 and a back plate 51 hinged to the front side of the seat plate 52. The front drive assembly 6 is disposed on the front side of the support frame 3 and drives the back plate 51 to rotate along the hinge end with the seat plate 52. Its advantages are that the back plate 51 is hinged to the seat plate 52, and with the cooperation of the front drive assembly 6, the tilt angle of the back plate 51 can be flexibly adjusted, which can meet the user's needs for various postures such as sitting up to read, half-lying to rest, and lying flat to sleep, without the need for additional backrests, thus improving the convenience and comfort of use. The drive assembly is integrated into the support frame 3, without occupying additional space under the bed, and while adapting to the lifting function, it also increases the multi-functionality of the bed.

[0074] In some possible embodiments of this utility model, such as Figure 1As shown, the bed board assembly 5 also includes a thigh board 53 and a lower leg board 54. One end of the thigh board 53 and the lower leg board 54 are hinged to each other, and the other end of the thigh board 53 is hinged to the rear side of the seat board 52. The other end of the lower leg board 54 is connected to the support frame 3 through a connecting rod 34. The two ends of the connecting rod 34 are respectively hinged to the lower leg board 54 and the support frame 3. The lifting electric bed also includes a rear drive assembly 7. The rear drive assembly 7 drives the thigh board 53 to rotate along the hinged end with the seat board 52, thereby driving the lower leg board 54 to rotate. Its beneficial effect is that the hinged design of the thigh board 53 and the lower leg board 54, together with the rear drive assembly 7, can realize the lifting and bending adjustment of the legs, which can help users relax leg muscles and relieve fatigue from sitting for a long time, especially suitable for the elderly and people recovering from surgery. The lower leg board 54 is linked to the support frame 3 through the connecting rod 34 to ensure that the leg adjustment process is smooth, without the risk of jamming or sudden drop, taking into account both functionality and safety.

[0075] In some possible embodiments of this utility model, such as Figure 1 As shown, the lifting electric bed also includes a surrounding frame assembly 8, which includes a front back panel 81, a rear panel 82, and two side panels 83 connecting the front back panel 81 and the rear panel 82. The front back panel 81, the rear panel 82, and the two side panels 83 are respectively fixed around the support frame 3 and rise and fall synchronously with the support frame 3. Its beneficial effect is that the surrounding frame assembly 8 surrounds the support frame 3, which can protect the internal structure of the bed board assembly 5, the lifting assembly 2, etc., prevent dust and foreign objects from entering the gaps and affecting the mechanical operation, and reduce the maintenance frequency. The surrounding frame rises and falls synchronously with the support frame 3, always keeping it flush with the bed surface, avoiding gaps between the lifting bed surface and the surrounding frame, ensuring a neat and uniform appearance, and preventing users' clothes and hands from being pinched by the gaps, thus improving safety.

[0076] In some possible embodiments of this utility model, such as Figure 2 As shown, the lifting electric bed also includes two guardrail components 9, which are respectively located on both sides of the support frame 3. The beneficial effect is that the guardrail components 9 on both sides can effectively prevent users from turning over and falling off the side of the bed while sleeping, reducing safety hazards. At the same time, the guardrails can also serve as "handrails" for users to get up, helping them to support their bodies from a lying position, making it easier to get in and out of bed, combining protection and auxiliary functions, and improving the convenience of use for special groups.

[0077] In some possible embodiments of this utility model, such as Figure 1As shown, the two guardrail components 9 can also be set on the same side of the support frame 3 to facilitate getting on and off the bed. The advantage is that the guardrail components 9 can be flexibly set on the same side of the support frame 3 to adapt to different usage scenarios. The double guardrails on the same side can enhance the protection strength on one side, while not affecting the getting on and off the bed space on the other side. This avoids the obstruction of traditional double guardrails to users who are used to getting on and off the bed on one side, and improves the flexibility and adaptability of use.

[0078] In some possible embodiments of this utility model, such as Figure 1 As shown, the lifting drive component 4 adopts an electric push rod. The fixed end of the electric push rod is hinged to the support frame 3, and the telescopic end is hinged to the connecting beam 26. Its advantages are that the electric push rod, as the lifting drive component 4, is easy to operate and does not require manual force, making it especially suitable for the elderly and people with mobility impairments. The electric push rod can precisely control the telescopic length, realize fine adjustment of the height of the support frame 3, and operate smoothly with low noise, improving the user experience. Its hinged design of "fixed end + telescopic end" can adapt to the rotation trajectory of the connecting rod bracket, avoid jamming during the driving process, and extend the service life of the drive structure.

[0079] In some possible embodiments of this utility model, such as Figure 1 As shown, the base frame 1 is a rectangular frame structure formed by a front base beam 11, a rear base beam 12, and two side base rods 13. One end of the front support rod 211 and the front top rod 212 are hinged to the front of the corresponding side base rod 13 and are spaced apart by a certain distance; one end of the rear support rod 221 and the rear top rod 222 are hinged to the rear of the corresponding side base rod 13 and are spaced apart by the same distance. The beneficial effect is that the rectangular frame base frame 1 has strong structural stability, can evenly distribute the overall weight of the bed, and is suitable for different ground environments; the front and rear support rods 221 and the top rods are hinged at intervals on the side base rods 13, which disperses the stress points of the connecting rod support and avoids excessive wear at a single hinge point; the uniform interval ensures the symmetry of the front and rear support structures, further optimizes the smoothness of lifting and reducing the probability of mechanical failure.

[0080] In some possible embodiments of this utility model, such as Figure 1As shown, the support frame 3 is a rectangular frame structure formed by a front support beam 31, a rear support beam 32, and two side support rods 33. The other end of the front support rod 211 is hinged to the front of the corresponding side support rod 33, and the other end of the rear support rod 221 is hinged to the rear of the side support rod 33. Its beneficial effects are that the rectangular frame support frame 3 can stably support the bed board assembly 5, ensure the bed surface is flat, and avoid the bed surface from sinking due to deformation of the support frame 3. The front and rear support rods 221 are hinged to the front and rear of the side support rods 33, so that the force of the support frame 3 is evenly distributed on the surrounding frame, improving the load-bearing capacity of the bed surface. The frame structure facilitates the installation and fixing of the bed board assembly 5 and the surrounding frame assembly 8, simplifies the assembly process, and reduces production and maintenance costs.

[0081] As described above, the electric lifting bed of this utility model has the following beneficial effects:

[0082] 1. Synchronous lifting mechanism

[0083] The lifting drive component 4 drives the transmission rod 23, causing the front connecting rod bracket 21 and the rear connecting rod bracket 22 to rotate synchronously, ensuring that the support frame 3 lifts and lowers smoothly, preventing the bed from tilting and improving safety during use.

[0084] 2. Reduce the travel dependence of drive components

[0085] The support frame 3 is raised and lowered by rotating the front support rod 211 and the rear support rod 221, which reduces the dependence on the stroke of the lifting drive component 4, expands the lifting height range, and meets different usage needs.

[0086] 3. Failure Protection Design

[0087] The front push rod 212 and the rear push rod 222 provide support for the front support rod 211 and the rear support rod 221, so that even if the lifting drive component 4 fails, the bed board can be prevented from falling suddenly, ensuring safe use.

[0088] 4. Symmetrical support structure on both sides

[0089] Two sets of front and rear connecting rod supports 22 are symmetrically arranged on both sides of the base frame 1, so that the support frame 3 is subjected to uniform force, avoiding force concentration on one side and improving structural stability.

[0090] 5. Horizontal linkage structure

[0091] The front drive beam 24 and the rear drive beam 25 connect the front support rods 211 and the rear support rods 221 on both sides to ensure synchronous rotation and avoid bed tilting or jamming caused by asynchronous movement of the support.

[0092] 6. Strengthen the structure to improve reliability

[0093] The front reinforcement structure 213 and the rear reinforcement structure 223 respectively enhance the deformation resistance of the front connecting rod support 21 and the rear connecting rod support 22, extend their service life, and ensure long-term stable operation.

[0094] 7. Multifunctional bed board adjustment

[0095] The bed board assembly 5 includes a seat board 52, a backrest board 51, a thigh board 53, and a lower leg board 54. Together with the front drive assembly 6 and the rear drive assembly 7, it enables various posture adjustments, improving user comfort and functionality.

[0096] 8. Frame assembly 8: protection and synchronous lifting

[0097] The frame assembly 8 surrounds the support frame 3, protecting the internal structure and preventing dust and foreign objects from entering. It also rises and falls synchronously with the support frame 3 to avoid gaps between the frame and the bed surface, thus improving safety.

[0098] 9. Flexible guardrail design

[0099] The guardrail assembly 9 can be installed on both sides or the same side of the support frame 3, and can be flexibly adjusted according to the usage scenario. It provides protection without hindering getting on and off the bed, thus improving the flexibility of use.

[0100] 10. Electric linear actuator drive

[0101] Using an electric push rod as the lifting drive component, it is easy to operate, runs smoothly, and has low noise, making it suitable for the elderly and people with mobility impairments, thus improving the user experience.

[0102] 11. Stable frame structure

[0103] The base frame 1 and support frame 3 adopt a rectangular frame structure, which has strong stability, can evenly distribute weight, adapt to different ground environments, and reduce the probability of mechanical failure.

[0104] This utility model's electric lifting bed, through its innovative lifting component 2 design, achieves smooth lifting and multi-functional adjustment of the bed body, solving the problems of limited lifting stroke, difficulty in synchronization, and certain failure risks in existing technologies. Its synchronous lifting mechanism and reinforced structure ensure the stability and reliability of the lifting process, while the multi-functional bed board adjustment and surrounding frame component 8 design enhance user comfort and safety. Flexible guardrail settings and electric push-rod drive further enhance the bed's applicability and user experience. This design is not only suitable for home use but also particularly well-suited for scenarios requiring special care, such as nursing homes and rehabilitation centers, providing users with a higher quality of experience.

[0105] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.

Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
