Description

Technical Field

[0001] This utility model relates to the field of electric mattress technology, specifically to a segmented electric mattress frame structure. Background Technology

[0002] Current electric mattresses typically employ a layered modular design, comprising a balancing base, an adjustable layer, and a cushioning layer. The core of the adjustable layer is the electric frame structure, which consists of a back section, a lumbar section, and a leg section. The lumbar section is fixedly connected to the balancing base to maintain a horizontal reference position, while the back and leg sections are adjusted in angle via electric actuators or other electric drive components, allowing the mattress to adapt to different usage needs.

[0003] Because fully assembled electric mattresses are typically over 2 meters long and over 1.5 meters wide, their overall transportation and logistics costs are high, and they easily exceed the size limits of doorways and elevators, making it difficult to deliver the product smoothly to the customer's designated location. Therefore, the industry commonly adopts split shipping, disassembling the whole mattress into multiple packages, making the dimensions of the split packages easier to transport and deliver to the customer's home.

[0004] Specifically, regarding the frame structure of the adjustment layer, the waist section serves as the structural hub, with push rods connecting to it for driving the back and leg sections. This structural characteristic presents a dilemma for the waist section during shipping: either it must be shipped as a single unit along with the connected push rods and part of the structure, or the push rods must be completely separated from the adjacent back and leg sections. When choosing to split the components, the customer receives the parts in an unassembled state, requiring on-site installation of the push rods, the hinge points with the back and leg sections, and the push rod bodies themselves. This assembly process involves numerous alignment and tightening of hinge points, as well as the installation and adjustment of the push rods. The steps are cumbersome and extremely unfriendly to non-professionals, often taking more than an hour for the first assembly, severely impacting the user's unboxing experience and product satisfaction. Utility Model Content

[0005] The purpose of this utility model is to provide a segmented electric mattress frame structure, which facilitates the separate shipment of the electric mattress frame structure, avoids exceeding the limits of doorway or elevator dimensions, reduces logistics costs, significantly reduces the difficulty of customer assembly, reduces the time required for assembly, and improves customer experience.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is: a segmented electric mattress frame structure, including a back section, a waist section, and a leg section that are hinged sequentially along the length of the mattress. The waist section includes a first split frame and a second split frame arranged parallel to each other along the length of the mattress. The first split frame and the second split frame are detachably and fixedly connected by a connector.

[0007] A further improvement of this utility model is that the first split frame is hinged to the back section, and the second split frame is hinged to the leg section. The first split frame is provided with a first driving member for driving the back section to rotate relative to it, and the second split frame is provided with a second driving member for driving the leg section to rotate relative to it.

[0008] A further improvement of this utility model is that the back section includes a back support frame, which is hinged to the first split frame.

[0009] A further improvement of this utility model is that the leg segment includes a thigh support frame and a calf support frame that are hinged together in sequence, and the end of the thigh support frame away from the calf support frame is hinged to the second split frame.

[0010] A further improvement of this utility model is that the top surfaces of the first split frame, the second split frame, the back support frame, the thigh support frame, and the calf support frame are all provided with mesh support members, and when the frame structure is in a flat position, the support surfaces of all the mesh support members are flush.

[0011] A further improvement of this utility model is that the lower ends of the first split frame and the second split frame are symmetrically provided with support structures for connecting the balance base frame, and the lower ends of the back support frame and the lower leg support frame are provided with limiting members. When the support surfaces of all the mesh support members are flush, the lower end surface of the support structure is flush with the lower end surface of the limiting member.

[0012] A further improvement of this utility model is that the lower leg support frame is provided with symmetrical fixing members on both sides, the support structure of the second split frame extends to the lower part of the thigh support frame and its extended end is hinged with a pull rod, and the other end of the pull rod is hinged to the fixing member.

[0013] A further improvement of this utility model is that the connecting member consists of at least two connecting pieces disposed between the first split frame and the second split frame, and each connecting piece is detachably and fixedly connected to the first split frame and the second split frame by bolts.

[0014] A further improvement of this utility model is that each of the back support frame and the first split frame is provided with a base for hinged mounting of the end of the first driving member, and the two ends of the first driving member are respectively hinged to the corresponding base. Each of the thigh support frame and the second split frame is provided with a base for hinged mounting of the end of the second driving member, and the two ends of the second driving member are respectively hinged to the corresponding base.

[0015] The beneficial effects of this utility model are as follows:

[0016] This invention splits the waist section into two independent frames, significantly reducing the size of a single package (for example, the original whole waist section package length may exceed 1 meter, but after splitting, it can be reduced to less than 0.5 meters), avoiding exceeding the size limits of doorways or elevators, reducing logistics costs, and ensuring smooth delivery to the home. On-site, only the first and second frames need to be fixed with connectors; there is no need to disassemble or install drive components or hinge points. The assembly process is simplified from the multi-step alignment and debugging of existing technologies to a single connection operation, greatly reducing the difficulty of assembly for customers, reducing the time required for assembly, and improving the customer experience.

[0017] In this invention, when the frame structure is in a flat position, the supporting surfaces of all the mesh support members are flush, ensuring a flat mattress surface and providing consistent comfort. The lower end surfaces of the support structure and the lower end surfaces of the limiting members are flush, together forming a supporting plane for the entire frame when it is in a flat position, preventing swaying or imbalance.

[0018] The connector of this invention is a connecting piece. The connecting piece has a simple structure and low manufacturing cost, and the bolt fixing provides a high-strength connection, ensuring the stability of the waist section as the overall central component. The bolt connection method does not require professional tools (a regular wrench is sufficient). Users only need to tighten a few bolts (e.g., 4) to complete the waist section integration, making the operation intuitive and user-friendly. Attached Figure Description

Detailed Implementation

[0027] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.

[0028] Example 1: Combination Figures 1-7 It is known that a segmented electric mattress frame structure includes a back section, a waist section and a leg section that are hinged sequentially along the length of the mattress. The waist section includes a first split frame 1 and a second split frame 2 that are arranged parallel to each other along the length of the mattress. The first split frame 1 and the second split frame 2 are detachably and fixedly connected to each other by a connector 3.

[0029] The back, waist, and leg sections are hinged together using existing hinges that allow for jointing between them. This enables flexible and controllable relative rotational movement between adjacent sections to meet the overall structural movement requirements.

[0030] In a preferred embodiment, each hinge point uses a hinge element comprising a pair of identical L-shaped metal connecting pieces. Each L-shaped connecting piece includes two rigid mounting edges perpendicular to each other at a 90-degree angle. The first mounting edge is rigidly fixed to the corresponding segment by fasteners (such as screws or rivets), while the second mounting edge extends perpendicular to the fixed edge and has a connecting through hole. During assembly, the second mounting edges of the two L-shaped connecting pieces are aligned parallel to each other, with their connecting holes precisely aligned. Subsequently, a through rigid pivot (e.g., a bolt or pin) passes through these aligned connecting holes and is locked in place by a nut or retaining ring. This allows the two connecting pieces (and consequently the segments they are fixed to) to rotate relative to each other about the axis of the pivot.

[0031] The first split frame 1 is hinged to the back section, and the second split frame 2 is hinged to the leg section. The first split frame 1 is provided with a first driving member 4 for driving the back section to rotate relative to it, and the second split frame 2 is provided with a second driving member 5 for driving the leg section to rotate relative to it. The first driving member 4 and the second driving member 5 are linear driving members with hinge points at both ends, such as electric push rods, hydraulic push rods, or pneumatic push rods, preferably electric push rods.

[0032] The first drive component 4 and the second drive component 5 are pre-installed and do not need to be separated during transportation. On-site assembly only requires connecting the split frame, without the need to deal with the alignment or adjustment of the hinge point of the push rod. The drive components are pre-installed in the factory to ensure the accuracy of the hinge point and avoid push rod failure or mattress adjustment failure caused by user installation errors on site, thereby improving product durability and user satisfaction.

[0033] The back section includes a back support frame 6, which is hinged to the first split frame 1 via hinges such as pins. The leg section includes a thigh support frame 7 and a calf support frame 8 that are hinged sequentially. The end of the thigh support frame 7 away from the calf support frame 8 is hinged to the second split frame 2 via hinges such as pins. The hinge points are pre-assembled at the factory to ensure hinge point accuracy, eliminating the need for on-site assembly by the customer.

[0034] The top surfaces of the first split frame 1, the second split frame 2, the back support frame 6, the thigh support frame 7, and the calf support frame 8 are all equipped with mesh support members 9 (the mesh support members 9 are rigid material mesh structures, such as metal wire mesh, composite material laminate mesh, engineering plastic mesh, etc.). When the frame structure is in a flat position, the support surfaces of all mesh support members 9 are flush. The support surfaces provide support for the adjustable layer located above the mesh support members 9 and the padding layer, ensuring that the mattress provides a uniform and comfortable sleeping surface when it is in a flat position.

[0035] The five frames—first split frame 1, second split frame 2, back support frame 6, thigh support frame 7, and calf support frame 8—each include at least two support frame rods arranged along the width of the mattress, and at least one reinforcing frame rod is provided between adjacent support frame rods in each frame.

[0036] The lower ends of both the first split frame 1 and the second split frame 2 are symmetrically provided with support structures 10 for connecting to the balance base frame (not shown in the figure). The lower ends of the back support frame 6 and the lower leg support frame 8 are provided with limiting members 11. When the support surfaces of all the mesh support members 9 are flush, the lower end surface of the support structure 10 is flush with the lower end surface of the limiting member 11. The support structure 10 is connected to the balance base frame by bolts. The support structure 10 includes longitudinal frame rods arranged along the length of the mattress, and the limiting member 11 includes transverse frame rods arranged along the width of the mattress. The lower ends of the first split frame 1 and the second split frame 2 are each provided with at least two longitudinal frame rods arranged along the length of the mattress, preferably four, and all four longitudinal frame rods are connected to the balance base frame.

[0037] The balancing base frame (or base frame, foundation frame) is a standard configuration commonly used in the existing technology of electric beds. Its core function is to provide a stable horizontal reference and load-bearing platform. In this utility model, this base frame is directly used as the basic support structure, and its design falls within the scope of common knowledge. Its typical structure consists of a main skeleton made of high-strength rectangular or square steel pipes, which are welded or bolted together to form a sturdy rectangular frame, ensuring the rigidity, levelness, and stability of the overall structure.

[0038] The calf support frame 8 has symmetrical fasteners 12 (such as welded or bolted metal ear plates) on both sides. The support structure 10 of the second split frame 2 extends below the thigh support frame 7, and its extended end is hinged to a pull rod 13. The other end of the pull rod 13 is hinged to the fastener 12. The pull rod 13 is used to provide linkage support when the calf support frame 8 is raised. Preferably, the fastener 12 is located on the calf support frame 8 near its hinge point with the thigh support frame 7. Preferably, the support structure 10 of the second split frame 2 includes four longitudinal frame rods arranged along the length of the mattress. The four longitudinal frame rods are spaced apart, and the two longitudinal frame rods on both sides extend below the thigh support frame 7, and their extended ends are hinged to the pull rod 13.

[0039] The connector 3 consists of at least two connecting pieces (such as metal strips) disposed between the first split frame 1 and the second split frame 2. Each connecting piece is detachably fixed to the first split frame 1 and the second split frame 2 by bolts. By removing these bolts, the waist section can be separated into the first split frame 1 and the second split frame 2, facilitating transportation or replacement. Preferably, two connecting pieces are provided to meet the connection requirements of the first split frame 1 and the second split frame 2. The stability of the first split frame 1 and the second split frame 2 can also be further improved by a balance base.

[0040] Each of the back support frame 6 and the first split frame 1 is provided with a base for hinged mounting of the end of the first driving member 4 (the base is a conventional base in the prior art that can provide a hinge point for the driving member, such as a metal base with a shaft hole). The two ends of the first driving member are respectively hinged to the corresponding base. Each of the thigh support frame 7 and the second split frame 2 is provided with a base for hinged mounting of the end of the second driving member 5. The two ends of the second driving member are respectively hinged to the corresponding base. The extension and retraction of the first driving member 4 drives the back support frame 6 to rotate around its hinge point with the first split frame 1, and the extension and retraction of the second driving member 5 drives the thigh support frame 7 to rotate around its hinge point with the second split frame 2. In turn, through the hinge between the thigh support frame 7 and the calf support frame 8 and the linkage of the pull rod 13, the calf support frame 8 is driven to move synchronously.

[0041] The working principle of the segmented electric mattress frame structure provided by this utility model is as follows:

[0042] When transportation or replacement is required, the bolts on the connecting plates can be unscrewed to separate the first split frame 1 and the second split frame 2. After separation, the back support frame 6 remains hinged to the first split frame 1, and the thigh support frame 7 remains hinged to the second split frame 2. The transportation or storage volume is significantly reduced. When needed, the first split frame 1 and the second split frame 2 are aligned and fixed together with bolts via the connecting plates to assemble the frame structure.
