[0002] Upholstered beds are becoming increasingly popular in furniture. Due to the limited space in typical bedrooms, upholstered beds occupy a relatively large proportion of the space. To make full use of bedroom space, it is necessary to expand the storage function of upholstered beds. Therefore, the space under the upholstered bed needs to be fully utilized. To ensure the comfort, safety, and convenient storage function of upholstered beds, foldable upholstered bed frames have become popular among consumers.

[0003] A search revealed a combined multi-posture sliding bed with application number CN202320392306.0, comprising a bed box and a bed frame; the bed frame and the bed box are hinged together by a linkage component, and under stress, the bed frame can cooperate with the linkage component to achieve lifting, tilting, lateral movement, and lateral movement to flatten operations; it facilitates the exposure of the space under the bed, making it convenient for use and storage.

[0004] However, in this solution, when the bed frame is being moved horizontally or lifted at an angle, it is supported by a main safety bar and a secondary safety bar to ensure overall safety. The main and secondary safety bars are fixed by inserting bolts into corresponding holes, which requires manual installation each time an adjustment is made, increasing the number of operation steps and time. The independent safety bars need to be stored separately when not in use, and there are many small parts required for installation. These parts are easily misplaced or lost when busy, resulting in poor subsequent fixing effect of the safety bars, which may lead to the bed board falling unexpectedly. Based on this, this solution provides a bed frame structure to solve the above-mentioned problems. Utility Model Content

[0010] Preferably, the first support component includes a connecting seat 1 fixedly installed on the inner wall of the left side of the bed frame, and a connecting seat 2 fixedly installed on the mounting frame. A rotating seat is rotatably installed on the connecting seat 1, and a fixed frame is fixedly installed on the rotating seat. A movable plate and a locking box are slidably connected to each other on the fixed frame. A snap-fit ​​hole is provided at the upper end of the movable plate for detachable snap-fit ​​with the connecting seat 2.

[0011] Preferably, a rotating shaft is rotatably installed inside the locking box. A knob is fixedly connected to one end of the rotating shaft, and a hinge frame is fixedly connected to the rotating shaft. Both ends of the hinge frame are provided with hinge slots, and a locking block is slidably connected inside the hinge slots on both sides.

[0016] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0017] Reference Figure 1-2 As shown, a bed frame structure includes a bed frame 1 and a bed board 2. The bed board 2 is disposed inside the bed frame 1, and two sets of symmetrically installed linkage mechanisms 3 are provided between the bed board 2 and the bed frame 1. The linkage mechanism 3 includes a mounting plate 301 fixedly installed on the inner wall of the bed frame 1 and a mounting bracket 302 fixedly installed at the lower end of the bed board 2. A first linkage component and a second linkage component are provided between the mounting plate 301 and the mounting bracket 302 to assist in lifting the bed board 2. A first support component 4 is provided between the left side of the mounting bracket 302 and the left inner wall of the bed frame 1, and a second support component 5 is provided between the second linkage component and the right inner wall of the bed frame 1.

[0018] Furthermore, the linkage mechanism 3, composed of linkage component one and linkage component two, enables the bed board 2 to be lifted quickly and effortlessly. During lifting, depending on the working conditions of linkage component one and linkage component two, the bed board 2 can be lifted in two different postures: one end is lifted or the entire bed board 2 is lifted. At the same time, for the two different postures, the first support component 4 and the second support component 5 are adjusted to be suitable for the bed board 2 in different postures and to support and fix it, ensuring the safety of the bed board 2 in the lifted posture.

[0019] Reference Figure 2 As shown, specifically in this embodiment, the linkage component one includes a first gas spring 303. The lower end of the first gas spring 303 is hinged to the left end of the mounting plate 301, and the upper end of the first gas spring 303 is hinged to the middle part of the mounting bracket 302.

[0020] Furthermore, the first gas spring 303 is a force-saving drive element. The high-pressure gas pre-charged inside provides a continuous thrust. When the user applies a small initial force to lift the bed board 2, this thrust can offset most of the weight of the bed board 2, mattress and bedding, making the lifting operation very easy.

[0021] Reference Figure 2As shown, specifically in this embodiment, the second linkage component includes a hinge plate 3041 hinged to the mounting plate 301, and a connecting rod 3042 hinged to the right end of the mounting bracket 302. The upper end of the hinge plate 3041 is hinged to the lower end of the connecting rod 3042. A second gas spring 304 is hinged to the lower end of the hinge plate 3041. The upper end of the second gas spring 304 is hinged to the bottom of the connecting rod 3042. A connecting rod 3043 is hinged between the lower end of the hinge plate 3041 and the mounting plate 301. A crossbeam 3044 is fixedly connected between the two connecting rods 3042.

[0022] Furthermore, the second linkage component, through the combination of hinge plate 3041, connecting rod 1 3042, connecting rod 2 3043, and the second gas spring 304, forms a four-bar linkage structure. Its function is to transmit and balance the lifting force, and when the right end of the bed board 2 is lifted, the second gas spring 304 provides auxiliary thrust, further optimizing the labor-saving effect and the smoothness of the movement. It is also rigidly connected to the two-sided mechanism through the crossbeam 3044 to ensure synchronous movement on both sides and enhance the overall structural rigidity.

[0023] Reference Figure 2-3 As shown, specifically, in this embodiment, the upper and lower ends of the first support component 4 are connected to the mounting bracket 302 and the left inner wall of the bed frame 1, respectively, and the upper and lower ends of the second support component 5 are connected to the crossbeam 3044 and the right inner wall of the bed frame 1, respectively. The overall structure and working principle of the first support component 4 and the second support component 5 are the same.

[0024] Furthermore: when the bed board 2 is lifted at the end near the first support component 4 under the drive of the linkage mechanism 3, the bed board 2 can be supported simply by adjusting the first support component 4. When the bed board 2 is fully lifted, the first support component 4 and the second support component 55 need to be adjusted together to support the bed board 2 to ensure overall safety.

[0025] Reference Figure 3 As shown, specifically in this embodiment, the first support component 4 includes a connecting seat 401 fixedly installed on the inner left side wall of the bed frame 1, and a connecting seat 403 fixedly installed on the mounting frame 302. A rotating seat 4011 is rotatably installed on the connecting seat 401, and a fixing frame 402 is fixedly installed on the rotating seat 4011. A movable plate 4021 and a locking box 4024 are slidably connected to each other on the fixing frame 402. A snap-fit ​​hole 4023 is provided through the upper end of the movable plate 4021 for detachable snap-fit ​​with the connecting seat 403.

[0026] Reference Figure 4As shown, specifically in this embodiment, a rotating shaft 4025 is rotatably installed inside the locking box 4024. A knob 40210 is fixedly connected to one end of the rotating shaft 4025, and a hinge frame 4026 is fixedly connected to the rotating shaft 4025. Both ends of the hinge frame 4026 are provided with hinge grooves 4027, and the interiors of the hinge grooves 4027 on both sides are slidably connected with locking blocks 4028. The outer ends of the locking blocks 4028 penetrate through the side wall of the locking box 4024 and extend outward. The surface of the fixing frame 402 is provided with several sets of locking grooves 4022 for engaging with the locking blocks 4028. Both sides of the hinge frame 4026 are provided with torsion springs 4029 sleeved on the rotating shaft 4025. The two ends of the torsion springs 4029 on both sides are fixedly connected to the inner wall of the locking box 4024 and the hinge frame 4026, respectively.

[0027] Reference Figure 5 As shown, specifically in this embodiment, the connecting seat 403 has an installation cavity 4031, and a plug rod 4032 is slidably installed inside the installation cavity 4031. One end of the plug rod 4032 is fixedly connected to a pull ring 4033, and the middle part of the plug rod 4032 is fixedly connected to a fixing ring 4034. A spring 4035 sleeved on the plug rod 4032 is fixedly connected between the fixing ring 4034 and the inner wall of the installation cavity 4031.

[0028] Furthermore: When the user tilts or fully raises the bed board using the linkage mechanism 3 composed of linkage component one and linkage component two, the user rotates the knob 40210, causing the hinge frame 4026 in the locking box 4024 to rotate, forcing the two locking blocks 4028 to retract inward and disengage from the slot 4022. At this time, the moving plate 4021 can be freely pulled out to adjust its length, allowing the moving plate 4021 to move towards the connecting seat 2 403 until the locking hole 4023 on the moving plate 4021 engages with the connecting seat 2. The insertion rod 4032 in 403 is coaxial. Then, by pulling the pull ring 4033, the insertion rod 4032 is inserted into the snap-fit ​​hole 4023 of the moving plate 4021, completing the connection between the moving plate 4021 and the connecting seat 403. Then, the knob 40240 is released, and the locking block 4028 automatically pops out and locks again under the action of the torsion spring 4029. The operation is convenient, and the force of the torsion spring 4029 and the spring 4035 makes the whole thing automatically lock after adjustment, preventing accidents caused by forgetting to lock.

[0029] Furthermore, the second connecting seat 403 enables quick connection and separation between the first support assembly 4 and the bed board 2. During connection: pulling the pull ring 4033 retracts the insertion rod 4032 into the second connecting seat 403. Then, align the snap-fit ​​hole 4023 of the moving plate 4021 with the insertion rod 4032. Next, release the pull ring 4033; under the action of the spring 4035, the front end of the insertion rod 4032 inserts into the snap-fit ​​hole 4023, completing the locking process. The overall structure is simple, installation is faster than using bolts, and there is no need to worry about losing parts.

[0030] Reference Figure 1 , 2 7. On the inner wall of the side panel of the bed frame 1, a bearing plate 6 is fixedly installed corresponding to the first support component 4 and the second support component 5 respectively. When the bed board 2 is placed flat on the inner side of the bed frame 1, the first support component 4 and the second support component 5 are both in a retracted or unlocked state. At this time, the first support component 4 and the second support component 5 can be stored on the bearing plate 6.

[0031] The working principle of this utility model is as follows: In the initial state, the bed board 2 is placed flat inside the bed frame 1 and is in a horizontal position. The first support component 4 and the second support component 5 are both in a retracted or unlocked state and do not participate in the support. The first support component 4 and the second support component 5 are stored on the support plate 6. Subsequently, with the assistance of the linkage mechanism 3, the left end of the bed board 2 can be lifted or the bed board 2 can be lifted completely. However, whether one end is lifted or the bed board 2 is lifted completely, the length of the support component needs to be adjusted to adapt to the new bed board angle. Taking the first support component 4 as an example: Rotating knob 40210 causes the hinge frame 4026 to rotate, causing the two locking blocks 4028 to retract inward and disengage from the slots 4022 on the fixed frame 402. At this time, the movable plate 4021 can be pulled out to adjust its extension length; then, pull ring 4033 on the connecting seat 2 403 is pulled to retract the insertion rod 4032, compressing the spring 4035, and aligning the locking hole 4023 at the top of the adjusted movable plate 4021 with the insertion rod 4032 on the connecting seat 2 403. Releasing pull ring 4033 causes the spring 4035 to push the insertion rod 4032 out and insert it into the locking hole 4023, completing the locking; then, releasing knob 40210 causes the torsion spring 4029 to automatically rotate the hinge frame 4026, causing the locking blocks 4028 to pop out and re-lock into the corresponding slots 4022 on the fixed frame 402, locking the length of the movable plate 4021. It is easy to operate. The force of the torsion spring 4029 and the spring 4035 makes the whole thing automatically lock after being adjusted to the correct position, preventing accidents caused by forgetting to lock it.

[0032] When the bed board 2 is lifted at the end near the first support component 4 under the drive of the linkage mechanism 3, the bed board 2 can be supported by adjusting the first support component 4. When the bed board 2 is fully lifted, the first support component 4 and the second support component 5 need to be adjusted together to support the bed board 2 to ensure overall safety.

[0033] The second support component 5 has the same structure as the first support component 4. Its upper end is connected to the crossbeam 3044, and its lower end is connected to the inner wall of the right side of the bed frame 1. Its length is adjusted in the same way so that it can connect the crossbeam 3044 and the inner wall of the right side of the bed frame 1.

[0034] When it is necessary to return the bed board 2 from its raised position to its flat position inside the bed frame 1, the user rotates the knob 40210, which drives the hinge bracket 4026 in the locking box 4024 to rotate, forcing the two locking blocks 4028 to retract inward and disengage from the slot 4022. Then, the user pulls the pull ring 4033 on the connecting seat 2 403, causing the insertion rod 4032 to retract and disengage from the locking hole 4023, compressing the spring 4035. Finally, the user moves the moving plate 4021 towards the connecting seat 1 401. This causes the movable plate 4021 to retract into the fixed frame 402. When the movable plate 4021 retracts to the appropriate position, the knob 40210 is then released, and the torsion spring 4029 automatically rotates the hinge frame 4026. The locking block 4028 pops out and re-locks into the corresponding slot 4022 of the fixed frame 402, locking the length of the movable plate 4021. Then, the retracted first support assembly 4 and second support assembly 5 are placed on the bearing plate 6, and the bed board 2 can then be reset.
