Description
Technical Field
[0001] This utility model relates to the field of smart home technology, and in particular to a compact folding electric bed. Background Technology
[0002] With the continuous development of the social economy and the steady improvement of technology, consumers have placed higher demands on the functionality, comfort, and spatial adaptability of home furnishings. Among many home furnishing products, the bed, as a core item for daily living, is particularly crucial for design iteration. Foldable electric beds, with their innovative folding and storage structure and intelligent drive system, not only possess a compact size and easy storage after folding, but also significantly reduce logistics and transportation costs. This has greatly promoted the development of online sales models for home furnishing products and met users' diverse needs for convenient assembly and flexible use, thus gaining popularity in the market.
[0003] However, existing folding bed technology still has significant limitations. From a structural design perspective, traditional folding beds generally rely on legs to support the bed frame, making it difficult to achieve maximum compression when folded, resulting in excessive space occupation and failing to meet the storage needs of space-constrained scenarios such as modern small apartments, RVs, and temporary residences. Regarding the drive system layout, existing folding beds mostly use fixed installation methods for their drive mechanisms, lacking adaptability to different usage scenarios and storage needs. This layout not only requires a large amount of space to flip the bed board, severely limiting its space utilization efficiency when used in low-ceilinged spaces or laid flat on the floor, but also prevents the expansion of electric functions by stacking it on a regular bed frame, limiting the product's application scenarios and functional boundaries.
[0004] In terms of drive mechanism performance, traditional folding beds typically use rigid, fixed connections for their drive mechanisms, making it impossible to adjust their position according to storage needs. This results in the overall thickness of the bed frame being difficult to compress effectively after folding, increasing storage difficulty and transportation costs. Furthermore, due to design flaws in the drive structure, the bed board is prone to jamming and abnormal noises during the flipping process, leading to insufficient smoothness of operation. This not only reduces the user experience but may also cause abnormal wear on mechanical parts, affecting the product's lifespan. Utility Model Content
[0005] 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 compact folding electric bed, which solves the problems of bulky size, difficult storage and logistics, and inability to be laid flat due to unreasonable layout and structure of the existing folding electric bed.
[0006] To solve the above-mentioned technical problems, this utility model provides a compact folding electric bed, comprising:
[0007] A support frame, comprising a front frame and a rear frame hinged to the front frame, wherein the front frame is a rectangular frame structure formed by a front support thick beam, a front connecting narrow beam and two front crank side rods, the front crank side rods comprising a horizontal rod and an inclined rod connected at one end, the front support thick beam being mounted on the other end of the horizontal rod, and the front connecting narrow beam being connected to the other end of the two inclined rods.
[0008] A front-flipping component and a rear-flipping component, wherein the front-flipping component and the rear-flipping component are respectively disposed at the front part of the front frame and the rear part of the rear frame;
[0009] The bed board includes a front seat board laid on the rear of the front frame, a back panel hinged to the front end of the front seat board, a rear seat board laid on the front of the rear frame, and a lower limb board hinged to the rear end of the rear seat board. The front flip-up assembly and the rear flip-up assembly are respectively connected to the back panel and the lower limb board.
[0010] Fold the front and rear frames along their hinges, and simultaneously fold the corresponding support plates mounted on them, so that the compact folding electric bed switches from the unfolded state to the folded state. In the folded state, the front flipping assembly and the rear flipping assembly are arranged alternately. The front support thick beam provides sufficient support strength in the unfolded state, the front connecting narrow beam provides sufficient space for folding in the folded state, and the front crank side rod expands the overall thickness of the support frame.
[0011] As a more preferred embodiment, the support frame further includes a flip hinge, through which the front and rear frames are hinged. The flip hinge includes two symmetrically arranged hinge ears and a pin connecting the two hinge ears. Each hinge ear includes a mounting portion and a connecting portion vertically fixed to the mounting portion. The connecting portion has a pin hole, and the pin passes through the pin holes of the two hinge ears to hinge them together. The advantage is that the flip hinge achieves a reliable hinge between the front and rear frames. The structural design of the hinge ears and pins makes the frame flipping action smoother and more stable, while ensuring the strength and stability of the connection, preventing loosening or damage during frequent folding and unfolding, and extending the product's service life.
[0012] As a more preferred approach, the connecting part is chamfered to provide the space required for folding between the hinge ears. The advantage of this approach is that the chamfering of the connecting part provides the necessary space for folding between the hinge ears, avoids interference between parts during folding, ensures that the electric bed can smoothly complete the folding action, and improves the reliability of the product and the convenience of user operation.
[0013] As a more preferred approach, the front support beam is provided with a clearance groove, and in the folded state, a portion of the rear flip-up component is engaged in the clearance groove. The advantage of this approach is that the clearance groove design on the front support beam provides a holding position for a portion of the rear flip-up component in the folded state, allowing the components to be arranged tightly after folding, further reducing the folded volume, while also increasing the overall compactness and aesthetics.
[0014] As a more preferred embodiment, the front-flipping assembly includes a front-flipping mechanism and a front-flipping drive. The front-flipping mechanism includes two front-flipping connecting rods and a front-flipping beam connected to the connecting rods at both ends. One end of each connecting rod is hinged to the front crank side rod, and the other end abuts against the back plate. The front-flipping drive is mounted on the front support beam and hinged to the front-flipping beam. The drive rotates the beam, which in turn rotates the connecting rods. The other end of each connecting rod lifts or lowers the back plate while sliding along its surface. The advantage is that the structural design of the front-flipping assembly allows for stable lifting and lowering of the back plate. The cooperation between the connecting rods and the beam, along with the drive, ensures precise control and smooth execution of the flipping motion, providing a comfortable user experience and meeting the needs of different posture adjustments.
[0015] As a more preferred approach, a pulley is provided at the other end of the front-flipping linkage. The advantages of this design are that the pulley at the end of the front-flipping linkage effectively reduces friction with the backplate, lowers wear, and extends the service life of the component. Simultaneously, the rolling support of the pulley makes flipping the backplate easier and less strenuous, improving the efficiency and stability of the action and enhancing the user experience.
[0016] As a more preferred embodiment, the rear frame is a rectangular frame structure formed by a rear support beam, a rear connecting beam, and two rear side rods. The mounting portions of the two hinge ears of the flip hinge are respectively fixed to the front connecting narrow beam and the rear connecting beam. The advantage is that the rectangular frame structure design of the rear frame echoes the front frame, improving the overall structural strength and stability. The reasonable layout of the mounting and connecting portions of the flip hinge makes the connection between the front and rear frames more stable, ensuring stability during folding and unfolding.
[0017] As a more preferred embodiment, the rear-flipping assembly includes a rear-flipping mechanism and a rear-flipping drive component. The rear-flipping mechanism includes a fixing frame fixed to the bottom of the lower limb plate and a connecting member disposed on the fixing frame. The rear-flipping drive component is disposed on the rear support beam and hinged to the connecting member. Its advantage lies in the fact that the structural design of the rear-flipping assembly enables the lower limb plate to achieve stable flipping movements. The placement of the fixing frame and connecting member, along with the cooperation of the rear-flipping drive component, ensures precise control and smooth execution of the flipping movement, providing comfortable support for the user's legs and the possibility of various posture adjustments.
[0018] As a more preferred embodiment, the front frame further includes several front support rods mounted on the horizontal bar. The tops of the front support rods, the front support beam, and the front connecting beam are horizontal to each other, allowing the back panel and front seat panel to lie flat on the front frame when unfolded. The advantage is that the front support rods ensure the back panel and front seat panel can lie flat on the front frame when unfolded, guaranteeing the flatness and comfort of the bed surface. The horizontal design of the front support rods, the front support beam, and the front connecting beam improves overall stability and load-bearing capacity, providing reliable support for the user.
[0019] As a more preferred embodiment, the lower limb plate includes a thigh plate hinged to the rear end of the rear seat plate and a calf plate hinged to the rear end of the thigh plate. The rear frame also includes a connecting rod, one end of which is hinged to the rear of the support frame, and the other end is hinged to the calf plate. The rear-flipping assembly is connected to the thigh plate, and by rotating the thigh plate, it in turn drives the calf plate to rotate. The advantage is that the design of the thigh and calf plates of the lower limb plate makes the leg support more ergonomic, better conforming to the leg curve and providing more comfortable support. The connection between the rear frame and the calf plate via the connecting rod, and the connection between the rear-flipping assembly and the thigh plate, achieves continuity and consistency in leg support, making leg support and movement more natural and meeting the needs of users in special scenarios such as leg care or rehabilitation.
[0020] As described above, the compact folding electric bed of this utility model has the following beneficial effects: the hinged design of the front frame and the rear frame allows the electric bed to flexibly switch between the unfolded state and the folded state. The thick front support beam provides sufficient support strength in the unfolded state, while the narrow front connecting beam provides enough space for folding in the folded state. The front crank side rod expands the overall thickness of the support frame, thus satisfying the rotation space required for the front and rear flip components to drive the back panel and lower limb panels to switch between different postures. This not only provides sufficient support strength in the unfolded state, ensuring the stability and load-bearing capacity of the bed, but also provides the necessary space for the front and rear flip components in the folded state, ensuring a compact layout of each component after folding, reducing the space occupied in storage, and improving space utilization. Secondly, the compact folding electric bed of this utility model uses the front and rear flip components to drive the back panel and lower limb panels to flip to different angles, realizing different postures of the bed board, thereby adapting to more usage scenarios and enriching the user experience. Finally, because the front crank side rod expands the overall thickness of the support frame, the internal space of the entire compact folding electric bed in the unfolded state can meet the rotation of the front and rear flip components, without the need to add bed legs to expand the space, thus meeting the need for flat use and making it possible to directly install it on a regular bed for expansion.
[0021] As can be seen, the compact folding electric bed of this utility model achieves a compact layout in the folded state, support strength and posture adjustment space in the unfolded state, and folding space when switching between the two states through the structural design of the front frame. It solves the problems of bulky size, difficult storage and logistics, and inability to lay flat for use caused by unreasonable layout structure of existing folding electric beds.

The front connecting narrow beam 112 provides the necessary space for folding, and the front crank side rod 113 strengthens the overall thickness of the support frame 1, ensuring that all components are tightly arranged after folding, reducing the storage volume.
[0056] 2. Structural strength and stability:
[0057] Front support beam 111: Provides sufficient support strength in the unfolded state to ensure the stability and load-bearing capacity of the bed.
[0058] Front crank side bar 113: Reinforces the overall thickness of the support frame 1, meets the rotation space requirements of the front flip assembly 2 and the rear flip assembly 3, eliminates the need for additional bed legs to expand the space, and adapts to the needs of flat use.
[0059] 3. Versatile usage options:
[0060] Forward flip component 2 and rearward flip component 3: The forward flip component 2 and rearward flip component 3 drive the back panel 41 and lower limb board 44 to flip to different angles, realize the multiple postures of the bed board 4, adapt to more usage scenarios, and enrich the user experience.
[0061] 4. Convenient operation and comfort:
[0062] Electric push rods: The front tilting drive unit 22 and the rear tilting drive unit 32 adopt electric push rods, which have the advantages of simple structure, convenient control and large thrust, reliably drive the tilting action, and improve the convenience and comfort of use.
[0063] Pulley 211a design: Pulley 211a is set at the end of the front flipping link 211 to reduce the friction between it and the back plate 41, reduce wear, extend the service life of the component, and make the flipping action easier and less strenuous.
[0064] 5. Ergonomic design:
[0065] Lower limb plate 44 design: The lower limb plate 44 includes a thigh plate 441 and a calf plate 442, which are ergonomically designed to provide more comfortable leg support. The rear-flipping assembly 3 is connected to the thigh plate 441 and drives the calf plate 442 to rotate via the connecting rod 125, achieving continuity and consistency in leg support.
[0066] 6. Rational use of space:
[0067] 111a clearance groove: The clearance groove 111a design on the front support beam 111 provides a locking position for a part of the rear flip component 3 in the storage state, further reducing the storage volume and increasing the overall compactness and aesthetics.
[0068] Bed board 4 clearance hole 5: The clearance hole 5 on the bed board 4 is designed to provide the necessary space for the flipping action of the front flipping assembly 2 and the rear flipping assembly 3, so as to avoid mutual interference between the parts.
[0069] This compact folding electric bed utilizes an innovative hinged design between the front frame 11 and the rear frame 12, enabling flexible switching between unfolded and folded states. Its core advantage lies in the structural design of the front support beam 111 and the front crank side rod 113, ensuring strong support in the unfolded state and a compact layout in the folded state. The front flip assembly 2 and the rear flip assembly 3 allow the bed board 4 to be adjusted to various postures to meet different user needs, improving comfort and convenience. The design of the electric push rod and pulley 211a further enhances the smoothness of operation and the lifespan of components. Overall, this invention solves the problems of bulky size, difficult storage, and inability to lay flat in existing folding electric beds due to unreasonable layout structures, providing a highly efficient, stable, and user-friendly folding electric bed solution.
