Description

Technical Field

[0001] This utility model relates to the field of storage bed support technology, and more specifically, to a hydraulic support device for storage beds. Background Technology

[0002] With modern living spaces becoming increasingly compact, people's demand for efficient use of living space is becoming more and more urgent. Storage beds are widely welcomed for their space-saving and multifunctional features. They not only meet daily sleeping needs, but can also be stored away when not in use, freeing up extra space for leisure, work, and other activities. However, the stability and safety of the support system are crucial during the unfolding and folding of storage beds. An unstable support system may cause the bed to shake or even collapse during use, threatening the user's safety. On the other hand, a support structure lacking a good safety design is prone to failure during frequent opening and closing, affecting the lifespan and user experience of the storage bed.

[0003] However, most hydraulic support devices for storage beds currently on the market only provide basic support. In some cases, the hydraulic system operates unevenly when the bed board opens and closes, easily generating significant impact forces that cause the bed to wobble. This not only affects the user experience but may also lead to structural loosening over time. Furthermore, some support devices lack effective cushioning, resulting in violent collisions between the bed board and the support device when the storage bed is closed, reducing the bed's lifespan and posing certain safety hazards.

[0004] Therefore, a hydraulic support device for storage beds is proposed to address the above-mentioned problems. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide a hydraulic support device for a storage bed. By setting hydraulic support components at both ends of a pair of circular connecting rods, and cooperating with fixed connecting rods, rotating hinge rods, and bed board fixed hinge rods, a stable support structure is formed. The fixing bolt mounting strip facilitates the secure installation of the support device on the storage bed frame. At the same time, the linkage design between the hydraulic rods and each hinge rod ensures smooth operation of the hydraulic system during the unfolding and folding of the bed board, effectively reducing impact force, preventing bed shaking, improving the stability and safety of the storage bed during use, and reducing the risk of structural loosening caused by shaking.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] The hydraulic support device of the storage bed includes a pair of circular connecting rods, a pair of hydraulic support components are respectively provided at the left and right ends of the pair of circular connecting rods, a buffer component is provided at one end of each pair of hydraulic support components, and an anti-collision rubber strip is provided at the lower end of the pair of buffer components.

[0010] Furthermore, the buffer assembly includes an upper fixed mounting plate fixedly connected to one end of the bed board fixed hinge rod. The upper fixed mounting plate is hinged to both the left and right ends of the upper fixed mounting plate. A pair of first buffer rods are hinged to sliding blocks at opposite ends.

[0016] In summary, this utility model has the following beneficial effects:

[0017] (1) This solution sets hydraulic support components at both ends of a pair of circular connecting rods, and forms a stable support structure in conjunction with fixed connecting rods, rotating hinge rods, and bed board fixed hinge rods. The fixed bolt installation strips facilitate the stable installation of the support device on the storage bed frame.

At the same time, the arc-shaped anti-collision rubber strip can better fit the contact surface, enhance the buffering effect, reduce safety hazards, and provide users with a more comfortable and safe user experience.

[0028] The hydraulic support assembly 2 includes a fixed connecting rod 201 fixedly connected to one end of a pair of circular connecting rods 1. A fixing bolt mounting strip 202 is fixedly connected to the lower end of the fixed connecting rod 201. A rotating hinge rod 203 is hinged to the rear end of the fixed connecting rod 201. A bed board fixing hinge rod 204 is hinged to the upper end of the rotating hinge rod 203. A pair of mutually symmetrical bed board fixing plates 205 are fixedly connected to the middle of the bed board fixing hinge rod 204.

[0029] The upper end of the fixed connecting rod 201 is hinged to a receiving hinge rod 206. The upper end of the receiving hinge rod 206 is rotatably connected to the lower end of the bed board fixed hinge rod 204. The upper end of the receiving hinge rod 206 is fixedly connected to a hinge block 207. The interior of the hinge block 207 is rotatably connected to a hydraulic rod 208. The upper end of the hydraulic rod 208 is rotatably connected to the lower end of the bed board fixed hinge rod 204.

[0030] This solution utilizes a hydraulic support assembly 2, consisting of a fixed connecting rod 201, a rotating hinge rod 203, a bed board fixed hinge rod 204, a receiving hinge rod 206, and a hydraulic rod 208, to achieve stable support for the bed board. The fixed connecting rod 201 is securely installed on the storage bed frame via fixing bolts and mounting strips 202, serving as a support base. The rotating hinge rod 203, the receiving hinge rod 206, and the bed board fixed hinge rod 204 are hinged together, and in conjunction with the extension and retraction drive of the hydraulic rod 208, a stable triangular support structure is formed, ensuring smooth operation of the bed board during unfolding and folding, while providing reliable support for the bed board.

[0031] The buffer assembly 3 includes an upper fixed mounting plate 301 fixedly connected to one end of the bed board fixed hinge rod 204. The upper fixed mounting plate 301 is hinged to both the left and right ends of the upper fixed mounting plate 301. A pair of first buffer rods 302 are hinged to the opposite ends of the pair of first buffer rods 302. A pair of sliding blocks 303 are hinged to the lower ends of the pair of sliding blocks 303. A first buffer spring 304 is fixedly connected to the lower end of the upper fixed mounting plate 301. A lower fixed plate 308 is hinged to the lower ends of the pair of second buffer rods 305.

[0032] A sliding housing 306 is slidably connected to the middle of a pair of sliding blocks 303. A second buffer spring 307 is fixedly connected to both the left and right ends of the sliding housing 306. A pair of second buffer springs 307 are fixedly connected to one end of a pair of sliding blocks 303 at their respective close ends. A receiving block 309 is fixedly connected to the lower end of the lower fixed plate 308.

[0033] This solution achieves a buffering and shock-absorbing effect by setting up a buffer assembly 3, utilizing components such as an upper fixed mounting plate 301, a first buffer rod 302, a sliding block 303, a second buffer rod 305, a first buffer spring 304, and a second buffer spring 307. When the bed board generates an impact force during opening and closing, the first buffer spring 304 is compressed first, absorbing some of the energy; at the same time, the first buffer rod 302 drives the sliding block 303 to slide within the sliding housing 306, compressing the second buffer spring 307 to further absorb the impact force. The sliding protrusion on the sliding block 303 cooperates with the strip-shaped sliding groove within the sliding housing 306 to ensure the stability and guidance of the sliding, making the buffering process smoother.

[0034] The lower ends of a pair of receiving blocks 309 are fixedly connected to the upper ends of the anti-collision rubber strip 4.

[0035] The lower end of the anti-collision rubber strip 4 is curved.

[0036] Sliding protrusions are fixedly connected to both the front and rear ends of the sliding block 303.

[0037] The sliding housing 306 has a pair of strip-shaped sliding grooves inside that cooperate with the sliding protrusions for sliding limit.

[0038] Specific implementation process: First, when the storage bed needs to be unfolded for use, the hydraulic rod 208 begins to extend, pushing the bed board fixed hinge rod 204 to rotate upward around the hinge point with the rotating hinge rod 203. At the same time, the receiving hinge rod 206 also rotates accordingly, forming a stable triangular support structure with the fixed connecting rod 201 and the rotating hinge rod 203. The bed board is connected to the bed board fixed hinge rod 204 through the bed board fixing plate 205. Driven by the hydraulic rod 208, it unfolds smoothly. The fixing bolt mounting strip 202 securely installs the entire hydraulic support assembly 2 onto the storage bed frame, ensuring a reliable connection between the support device and the bed body. The circular connecting rod 1 connects the hydraulic support assemblies 2 on both sides, enhancing overall stability. If an impact force is generated during the unfolding or folding of the bed board, the buffer assembly 3 begins to function. When the first buffer spring 304 is subjected to an impact force, it will be compressed. The first buffer rod 302 retracts, absorbing some energy. Simultaneously, the first buffer rod 302 drives the sliding block 303 to slide within the sliding housing 306, compressing the second buffer spring 307. The second buffer spring 307 further absorbs energy. The sliding protrusion on the sliding block 303 cooperates with the strip-shaped sliding groove within the sliding housing 306 to ensure the stability of the sliding block 303. Finally, the anti-collision rubber strip 4 contacts the contact surface. Its arc design allows it to better conform to the surface. Through its own elastic deformation, it buffers the impact force again. The multi-level buffer structure works synergistically to effectively reduce the collision force between the bed board and the support device, protecting the bed and the support device. When the folding bed needs to be folded up, the hydraulic rod 208 retracts, driving the bed board fixing hinge rod 204 to rotate downwards, and the bed board is slowly folded up. During this process, the buffer assembly 3 can also reduce the impact force of the bed board descending, ensuring a smooth and safe folding process.
