Description

Technical Field

[0001] This utility model relates to the field of furniture structure technology, and in particular to a bed frame connection structure that can be quickly disassembled and assembled. Background Technology

[0002] With increasingly compact urban living spaces and growing demand for portable, multifunctional furniture, mobile sleep solutions such as folding beds and storage beds have been widely used in homes, apartments, dormitories, temporary shelters, and outdoor camping. Among these, the bed frame, as the core structure supporting the bed, directly affects the user experience and product practicality due to its ease of assembly and disassembly, stability during unfolding, and storage efficiency.

[0003] Currently, traditional bed frames mostly use wooden frames or welded metal structures, which have high structural rigidity and load-bearing capacity, but have significant drawbacks such as large size, heavy weight, non-disassembly, or difficulty in transportation. They cannot meet the modern demand for lightweight, modular, and quick-deployment furniture. To solve this problem, various modular bed frame structures have been developed in existing technologies. These typically use bolts, screws, or other fasteners to connect multiple rods or frame components separately, allowing for a certain degree of disassembly and assembly. However, the disassembly and assembly process requires multiple tools to complete multi-point fastening, making the assembly steps cumbersome, time-consuming, and difficult for users to operate, thus failing to achieve quick assembly and disassembly.

[0004] Therefore, there is an urgent need to provide a bed frame connection structure that can be quickly assembled and disassembled. Utility Model Content

[0005] In order to overcome the shortcomings of existing wooden or welded metal bed frame structures that are not detachable and difficult to transport, as well as the cumbersome assembly steps, tool requirements, and inconvenient disassembly of existing modular bed frame structures, this utility model provides a bed frame connection structure that can be quickly disassembled and assembled.

[0006] To address the aforementioned issues, this utility model employs the following technical solution: a bed frame connection structure that allows for quick assembly and disassembly, comprising a first support frame, on both sides of which bed boards are hinged together via a hinge structure, each bed board having symmetrically distributed fixed seats at its bottom, adjacent fixed seats being hinged together to form a second support frame, each second support frame having a torsion spring fitted at its hinge point with its corresponding fixed seat, the two ends of the torsion spring being fixedly connected to the second support frame and the fixed seat respectively, guide rods being fixedly mounted on both sides of the bed board, sliders being slidably mounted on the guide rods, a U-shaped limiting plate being provided between adjacent sliders, each slider having a first magnet at both ends, and the guide rods having a second magnet at both ends.

[0007] Furthermore, the first support frame and the second support frame are made of H-shaped steel structure or high-strength aluminum alloy profile.

[0008] Furthermore, a mounting block is fixedly installed on the bottom of one side of the bed board, and circular locking holes are opened on both sides of the mounting block. Symmetrically distributed guide seats are fixedly installed on the bottom of the other side of the bed board. A slide rod is slidably installed on the guide seat. A circular locking block is installed at the inner end of the slide rod. An elastic element is sleeved on the slide rod. The two ends of the elastic element are fixedly connected to the circular locking block and the guide seat, respectively.

[0009] Furthermore, anti-slip pads are provided at the bottom of each support point of the first support frame and the second support frame.

[0010] Furthermore, a first positioning plate is fixedly installed on both sides of the top of the first support frame.

[0011] Furthermore, a second positioning plate is fixedly installed on the top of the bed board, and the second positioning plate and the first positioning plate together form a rectangular limiting frame.

[0012] Compared with the prior art, the present invention has the following technical effects: 1. The bed frame connection structure realizes the folding and quick-closing function of the bed board and the second support frame by setting a hinge structure between the bed board and the first support frame and between the second support frame and the bed board. Combined with the torsion spring, guide rod, slider, U-shaped limiting plate and the first magnet and second magnet distributed at the ends of the slider and guide rod, the second support frame can quickly and automatically pop out to the vertical support position under the action of the torsion spring's restoring force in the unlocked state, realizing rapid adaptive reset. During the folding process, the U-shaped limiting plate moves inward with the slider to push the second support frame upward and locks it stably through the inner magnetic attraction pair after it is in place, which significantly improves the assembly efficiency, safety of use and storage reliability of the bed frame.

[0013] 2. An automatic locking mechanism is formed by mounting blocks, circular locking blocks, sliding rods, and elastic elements located at the bottom of the left and right bed boards. This mechanism locks the two independent bed boards together during the folding process, preventing them from loosening, unfolding, or being damaged by collisions during transportation, thus improving the reliability of the product and the user experience.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1: Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 5A quick-assembly and disassembly bed frame connection structure includes a first support frame 1 and a second support frame 4. The first support frame 1 has bed boards 2 hinged to its left and right sides via hinge structures. The bed boards 2 can be unfolded outwards or folded inwards around the hinge points from 0 to 90 degrees. Each bed board 2 has two symmetrically distributed fixing seats 3 at its bottom. Two adjacent fixing seats 3 are hinged together to a second support frame 4. The second support frame 4 can be unfolded outwards or folded inwards around the hinge points from 0 to 90 degrees. When the second support frame 4 is fully unfolded, it and the first support frame 1 are perpendicular to the plane of the bed board 2, providing vertical support and enhancing the bed's structural integrity. The overall rigidity and stability of the frame are improved. Furthermore, the first support frame 1 and the second support frame 4 are constructed entirely of H-beam steel or high-strength aluminum alloy profiles, exhibiting excellent bending resistance and lightweight characteristics, thus enhancing the overall structural strength and durability. A torsion spring 5 is fitted onto the hinge point of each second support frame 4 and its corresponding fixed seat 3. The front and rear ends of the torsion spring 5 are fixedly connected to the second support frame 4 and the fixed seat 3, respectively. In its natural state, the torsion spring 5 is in a pre-tightened deformation state, generating a restoring torque that causes the second support frame 4 to spring outwards and tend towards a 90-degree unfolded position, thereby ensuring that the second support frame 4 can automatically return to a vertical support posture. The bed board 2 is fixed on both its front and rear sides. A guide rod 6 is fixedly provided, and a slider 7 is slidably mounted on the guide rod 6. A U-shaped limiting plate 8 for mechanically limiting and locking the second support frame 4 is provided between two adjacent sliders 7. Each slider 7 has a first magnet 9 at both ends, and the guide rod 6 has a second magnet 10 at both ends. When the slider 7 is in its initial position, the first magnet 9 and the second magnet 10 form an outer magnetic attraction pair to stably hold the slider 7 and the U-shaped limiting plate 8 in their initial standby position. When the slider 7 slides inward to its limit position, the inner first magnet 9 and another set of second magnets 10 at the inner end of the guide rod 6 form an inner magnetic attraction pair. The side magnetic attraction pair enables secondary locking of the U-shaped limiting plate 8. Each support point of the first support frame 1 and the second support frame 4 is provided with an anti-slip pad 16. The anti-slip pad 16 is made of elastic and wear-resistant material and is used to increase the friction between the bed frame and the ground to prevent the bed from sliding due to personnel movement or external force during use. The first positioning plate 17 is fixedly installed on the front and rear sides of the top of the first support frame 1, and the second positioning plate 18 is fixedly installed on the top of the bed board 2. The second positioning plate 18 and the first positioning plate 17 together form a rectangular limiting frame to limit the mattress in the circumference, effectively preventing the mattress from sliding laterally or falling off accidentally during use.

[0022] Under normal use, the left and right bed boards 2 are horizontal and flush with the first support frame 1, while the second support frame 4 is vertically extended at 90 degrees under the preload of the torsion spring 5. Simultaneously, the U-shaped limiting plate 8 is initially positioned outside the guide rod 6, held in place by the magnetic attraction of the outer first magnet 9 and the second magnet 10, without interfering with the free extension of the second support frame 4. At this time, the first support frame 1, the second support frame 4, and the bed board 2 together form a stable bed frame structure. When handling, transferring, or storing is required, a push is applied to push the U-shaped limiting plate 8 inward, overcoming the outer magnetic attraction, causing it to drive the slider 7 to slide inward along the guide rod 6. As the U-shaped limiting plate 8 moves inward, it gradually contacts and pushes the second support frame 4, forcing the second support frame 4 to fold upward around the hinge point. During the process, the torsion spring 5 is further torsionally compressed, storing elastic potential energy. When the second support frame 4 is fully retracted to fit the bottom surface of the bed board 2, the U-shaped limiting plate 8 continues to move forward to the final position and locks the second support frame 4 in place. At this time, the first magnet 9 on the inner side of the slider 7 and the second magnet 10 on the inner end of the guide rod 6 achieve magnetic attraction and locking, so that the U-shaped limiting plate 8 firmly fixes the second support frame 4 in the folded state. Subsequently, the left and right bed boards 2 are flipped down and folded to the side of the first support frame 1, realizing the compact folding and storage of the entire bed frame. When it is needed to be used again, simply pull the U-shaped limiting plate 8 outward to release the inner magnetic attraction and locking. Under the restoring force accumulated by the torsion spring 5, the second support frame 4 instantly and automatically pops out to the vertical support position, completing the adaptive reset, thereby achieving the purpose of quick disassembly and assembly.

[0023] Example 2: Based on Example 1, please refer to... Figure 4 The left side of the bed board 2 has a mounting block 11 fixedly installed at its bottom. The mounting block 11 has circular locking holes on both its front and rear sides. The right side of the bed board 2 has two guide seats 12 symmetrically distributed at its bottom. The guide seats 12 have sliding rods 13 slidably installed on them. The inner end of the sliding rod 13 has a circular locking block 14. The contact surface of the circular locking block 14 adopts a smooth arc-shaped transition structure, which facilitates self-guidance and insertion during docking. The sliding rod 13 is fitted with an elastic element 15. The front and rear ends of the elastic element 15 are fixedly connected to the circular locking block 14 and the guide seat 12, respectively. Under normal conditions, the elastic element 15 is in a free state and applies a continuous inward reset force to the circular locking block 14 to ensure that the circular locking block 14 has the ability to quickly return to its original position.

[0024] As the bed frame enters the folding process, the left and right bed panels 2 rotate downwards around their respective hinge points with the first support frame 1 until they are close together and folded into place on the left and right sides of the first support frame 1. During this process, the mounting block 11 on the left bed panel 2 gradually approaches the circular locking block 14 on the right bed panel 2. The side wall of the mounting block 11 first contacts the smooth transition surface of the circular locking block 14 and applies a radial thrust to the circular locking block 14. This thrust overcomes the elastic force of the elastic element 15 and pushes the slide rod 13 and the circular locking block 14 to slide outwards together, causing the elastic element 15 to be compressed and stored, while making room for the mounting block 11. As the bed panel 2 is folded into place, the circular locking hole on the mounting block 11 and the circular locking block are now aligned. Alignment 14. Under the release of the potential energy stored in the elastic element 15, the slide rod 13 drives the circular locking block 14 to quickly return to its original position, so that the circular locking block 14 is embedded in the circular locking hole of the mounting block 11, forming a mechanical interlock. Thus, the left and right bed boards 2 are reliably locked together in the folded state, effectively preventing unexpected unfolding caused by vibration, tilting or external force disturbance, and significantly improving the overall rigidity and safety of the folded state. When it is necessary to unfold and use again, the user can manually pull the outer end of the slide rod 13 outward to overcome the resistance of the elastic element 15, so that the circular locking block 14 is disengaged from the circular locking hole and the lock is released. Then the two bed boards 2 can be flipped up and unfolded to the horizontal working position to complete the quick installation.
