Description

Technical Field

[0001] This utility model relates to the field of smart home technology, and in particular to a legless, flat-lying folding bed. Background Technology

[0002] As society progresses and people's living standards improve, they place higher demands on the functionality and quality of home furnishings. Among the many home furnishings available, the choice of a bed is particularly crucial. To meet the need for portability, foldable electric beds are widely favored by consumers due to their innovative folding design. These beds are compact when folded, making them easy to store, while significantly reducing logistics costs and making online purchase and self-assembly possible.

[0003] Traditional folding beds typically require legs to support the bed frame, taking up a significant amount of space when folded, making them inconvenient for storage in limited spaces. Furthermore, the layout of the drive mechanism in existing folding beds is not ideal, resulting in a large space required for the bed board to flip, limiting their application in certain scenarios. For example, when used flat on the floor, the space under the bed board is underutilized, and there's no way to extend the electric flipping function by stacking them on a regular bed.

[0004] The existing drive mechanism design of folding beds also has shortcomings. The fixed position of the drive unit makes it impossible to optimize the layout according to storage needs, resulting in a larger overall thickness of the bed when folded, increasing the difficulty of storage. At the same time, the drive unit is not smooth enough when turning the bed board, affecting the user experience. 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 legless, flat-laying folding bed, which solves the problems of excessive thickness, difficult storage and logistics, and difficulty in laying flat caused by the unreasonable layout of the drive device in the prior art.

[0006] To solve the above-mentioned technical problems, this utility model provides a legless, flat-lying folding bed, comprising:

[0007] The base frame includes a front support frame and a rear support frame that are hinged together at one end;

[0008] The support plate includes an upper limb plate and a front seat plate disposed on a front support frame, a rear seat plate and a lower limb plate disposed on a rear support frame, the front seat plate being fixed to the rear part of the front support frame, one end of the upper limb plate being hinged to the front seat plate, the rear seat plate being fixed to the front part of the rear support frame, and one end of the lower limb plate being hinged to the rear seat plate.

[0009] A front drive unit, comprising a front drive member and a front drive mechanism, wherein the front drive mechanism is disposed on the front support frame and connected to the upper limb plate, and the front drive member drives the upper limb plate to rotate along the hinge end with the front seat plate through the front drive mechanism.

[0010] A rear drive device, comprising a rear drive component and a rear drive mechanism, wherein the rear drive mechanism is mounted on the rear support frame and connected to the lower limb plate, and the rear drive component drives the lower limb plate to rotate along the hinge end with the rear seat plate through the rear drive mechanism.

[0011] Fold the front support frame and the rear support frame along their hinge joints, and at the same time fold the support plate, so that the legless flat electric bed switches from the unfolded state to the stored state. In the stored state, the front drive component, the rear drive component, the front drive mechanism, and the rear drive mechanism are arranged alternately.

[0012] As a more preferred approach, the front drive mechanism is located on the front or rear side of the front support frame, and the rear drive mechanism is located on the corresponding front or rear side of the rear support frame, thereby satisfying the staggered arrangement of the front and rear drive mechanisms in the storage state. Its beneficial effect is that this flexibility enables the staggered arrangement of the front and rear drive mechanisms in the storage state, further optimizing space utilization and improving the storage efficiency of the product.

[0013] As a more preferred approach, the front drive component is positioned on the left or right side of the front support frame, and the rear drive component is positioned on the corresponding right or left side of the rear support frame, thereby satisfying the staggered arrangement of the front and rear drive components in the storage state. Its advantages are: increased layout flexibility, which helps to further reduce the overall thickness after storage, and improves the space utilization and logistics convenience of the product.

[0014] As a more preferred approach, a pad is provided at the bottom of the base frame. The pad is used to further increase the space at the bottom of the support plate required for the front and rear drive devices to rotate the support plate. Its advantages are: ensuring the smooth movement of each component when the support plate is rotated, avoiding interference with the ground, and preventing slippage and damage.

[0015] As a more preferred embodiment, the front drive mechanism includes a front rotating rod rotatably mounted on the front support frame and a front push rod disposed at the end of the front rotating rod. When the front drive member rotates the front rotating rod, the front push rod causes the upper limb plate to flip. Its advantages are: this mechanical transmission method has a simple structure, reliable operation, and can effectively convert the power of the front drive member into the flipping action of the upper limb plate, thereby improving the driving efficiency.

[0016] As a more preferred embodiment, the chassis also includes a front support rod, one end of which is fixed to the front support frame and the other end to the front seat plate. The advantages of this feature are that the front support rod enhances the connection strength between the front support frame and the front seat plate, improves the stability and load-bearing capacity of the entire structure, and ensures safety and reliability during use.

[0017] The front support rod is connected to the front drive mechanism via a clamping structure. The clamping structure includes a matching clamping member and a sleeve. The clamping member is fitted onto the front rotating rod of the front drive mechanism, and the sleeve is fitted onto the outside of the clamping member. The sleeve also has fixing ears on both sides, each with a fixing hole. A locking member passes through the fixing hole to fix the fixing ear to the corresponding front support rod, thus facilitating the connection between the front drive mechanism and the corresponding front support rod. The advantages are that the clamping structure provides a convenient connection method, allowing the front drive mechanism to be easily connected to the front support rod. This design simplifies the installation and maintenance process, improving product assembly efficiency and convenience.

[0018] As a more preferred method, the front push rod is equipped with rollers, and in the unfolded state, the rollers abut against the upper limb plate. When the front push rod drives the upper limb plate to flip, the front push rod slides on the upper limb plate through the rollers, which makes the flipping of the upper limb plate smoother. Its beneficial effect is that it reduces the friction during the flipping process, making the flipping of the upper limb plate smoother, improving the comfort of use and the smoothness of operation.

[0019] As a more preferred approach, in the folded state, the front support frame is folded inside the rear support frame; its advantage is that the stacking design of the front and rear support frames in the folded state further saves storage space.

[0020] As a more preferred embodiment, the rear drive mechanism includes a drive frame fixed to the bottom of the lower limb plate and a hinge portion disposed on the drive frame. The rear drive component is hinged to the hinge portion, and a clearance hole is provided at a corresponding position on the lower limb plate to prevent interference between the rear drive component and the drive frame when the rear drive component drives the drive frame to rotate. The advantages are: the design of the rear drive mechanism and the clearance hole avoids interference between the rear drive component and the lower limb plate during rotation; ensures smooth flipping action and improves the rationality and reliability of the structure; at the same time, the design of the clearance hole also overlaps a portion of the space required for the movement of the rear drive component with the thickness of the lower limb plate, further saving space.

[0021] As described above, the legless flat folding bed of this utility model has the following beneficial effects: When in use, the legless flat folding bed supports the user in its unfolded state. Simultaneously, the front drive component, through the front drive mechanism, rotates the upper limb board along the hinged end with the front seat board, and the rear drive component, through the rear drive mechanism, rotates the lower limb board along the hinged end with the rear seat board, allowing the legless flat folding bed to present different postures to meet the user's needs in different lying scenarios. Secondly, by folding the front and rear support frames along their hinges, it can be quickly switched to a folded state. In the folded state, the front and rear drive components, the front drive mechanism, and the rear drive mechanism are staggered, thereby reducing the overall thickness of the folding bed in the folded state. Furthermore, the reasonable arrangement of the front and rear drive components, the front drive mechanism, and the rear drive mechanism further saves the bottom space of the support plate required for the front and rear drive devices to rotate the support plate in the unfolded state, thus meeting the needs of scenarios where the base frame is placed flat on the ground.

[0022] This utility model of a legless, flat-laying folding bed, through the reasonable arrangement of the front drive component, rear drive component, front drive mechanism, and rear drive mechanism, saves the overall thickness of the folding bed in the folded state and the space required for the rotation of each component in the unfolded state. It improves the convenience of storage and meets the needs of flat-laying use scenarios, solving the problems of large thickness, difficult storage and logistics, and difficulty in flat-laying caused by unreasonable layout of drive devices in existing folding beds.

[0037] Fold the front support frame 11 and the rear support frame 12 along their hinge joints, and at the same time, fold the support plate 2 in half, so that the legless flat electric bed switches from the unfolded state to the stored state. In the stored state, the front drive component 31 and the rear drive component 41, the front drive mechanism 32 and the rear drive mechanism 42 are arranged alternately.

[0038] To better illustrate the legless, flat-lying folding bed of this utility model, the following specific application will be used as an example: When using the legless, flat-lying folding bed of this utility model, as follows... Figure 1 as well as Figure 2 As shown, the unfolded state supports the user, while the front drive component 31 drives the upper limb plate 21 to flip along the hinge end with the front seat plate 22 via the front drive mechanism 32, and the rear drive component 41 drives the lower limb plate 23 to flip along the hinge end with the rear seat plate 24 via the rear drive mechanism 42, allowing the legless folding bed to present different postures to meet the user's needs in different lying scenarios; secondly, the front support frame 11 and the rear support frame 12 can be folded along their hinge points to quickly switch to the storage state, such as... Figure 3As shown, in the folded state, the front drive component 31, the rear drive component 41, the front drive mechanism 32, and the rear drive mechanism 42 are arranged in an alternating manner, thereby reducing the overall thickness of the folding bed in the folded state.

It can be seen that the legless flat folding bed of this utility model, through the reasonable arrangement of the front drive component 31, the rear drive component 41, the front drive mechanism 32, and the rear drive mechanism 42, saves the overall thickness of the folding bed in the folded state and the space required for the rotation of each component in the unfolded state, improves the convenience of storage and meets the scenario requirements for flat use, and solves the problems of large thickness, difficult storage and logistics, and difficulty in flat placement caused by unreasonable layout of drive devices in the prior art.

The clamping member is sleeved on the front rotating rod 321 of the front drive mechanism 32, and the sleeve is sleeved on the outside of the clamping member. The sleeve also has fixing ears on both sides, each with a fixing hole. A locking member passes through the fixing hole to fix the fixing ear to the corresponding front support rod 5, thus facilitating the connection between the front drive mechanism 32 and the corresponding front support rod 5. The advantage is that the clamping structure 6 provides a convenient connection method, allowing the front drive mechanism 32 to be easily connected to the front support rod 5. This design simplifies the installation and maintenance process, improving the assembly efficiency and convenience of the product.

[0046] In some possible embodiments of this utility model, such as Figure 1 As shown, the front push rod 322 is equipped with a roller 322a. In the unfolded state, the roller 322a abuts against the upper limb plate 21. When the front push rod 322 drives the upper limb plate 21 to flip, the front push rod 322 slides on the upper limb plate 21 through the roller 322a, which makes the flipping of the upper limb plate 21 smoother. Its beneficial effect is that it reduces the friction during the flipping process, makes the flipping of the upper limb plate 21 smoother, and improves the comfort of use and the smoothness of operation.
