Description

Technical Field

[0001] This utility model belongs to the field of bed technology and relates to a pneumatic bed. Background Technology

[0002] An existing pneumatic bed includes a bed frame and a slatted frame. The slatted frame is connected to the bed frame by two connecting rods, so that the tail end of the slatted frame can be raised and lowered relative to the bed frame. A gas spring is installed between one of the connecting rods and the slatted frame, and the two connecting rods are located below the slatted frame. The slatted frame is restricted by the connecting rods and cannot be opened to a large extent. Summary of the Invention

[0003] This utility model addresses the problems existing in the prior art by proposing a pneumatic bed, aiming to overcome the defect of the small opening range of the slat frame of the existing pneumatic bed.

[0004] This utility model is implemented as follows:

[0005] A pneumatic bed includes a bed frame and a slatted frame, characterized in that the bed frame and the slatted frame are hinged at the head end, the hinge position between the bed frame and the slatted frame is higher than the upper end of the slatted frame, and a gas spring is provided between the bed frame and the slatted frame.

[0006] When the slatted frame moves up and down, the special position of the hinge point allows it to rotate around a point higher than its own top. During the ascent, the slatted frame is no longer significantly restricted by the lower connecting rod as in existing technologies; instead, it rotates around the higher hinge point, allowing the slatted frame to open more fully, making it easier for users to retrieve or place items underneath.

[0007] Preferably, the bed frame and the slatted frame are hinged together, and the hinge includes a first connecting part fixedly connected to the bed frame and a second connecting part fixedly connected to the slatted frame. The bed frame and the slatted frame are typically made of wood, while the hinges can be made of metal materials such as stainless steel. The hinges provide a stable and reliable connection between the bed frame and the slatted frame.

[0008] Preferably, the bed frame includes a first headboard and side panels. The first connecting portion includes a first fixing plate fixedly connected to the first headboard, and the outer edge of the first fixing plate has a first side fixing plate fixedly connected to the side panels. The first fixing plate is fixed to the first headboard, establishing the initial connection between the hinge and the headboard. The first side fixing plate extends from the outer edge of the first fixing plate and is fixed to the side panel. Through this structure, the hinge is tightly connected to both the first headboard and the side panels of the bed frame. When the slatted frame moves up and down, the force is transmitted to the first fixing plate through the hinge, and then distributed to the first headboard by the first fixing plate. At the same time, the first side fixing plate transmits part of the force to the side panels. The overall structure of the bed frame is used to jointly bear and distribute the force, ensuring the stability of the connection.

[0009] Preferably, the first headboard has a backrest that extends above the side panels. The outer edge of the portion of the first fixing plate corresponding to the backrest has an outer limiting edge, and the inner edge of the first fixing plate has an inner limiting edge. The upper ends of the outer and inner limiting edges are provided with hinge shafts that are hinged to the second connecting part. The second connecting part is located between the outer and inner limiting edges. The outer and inner limiting edges on the first fixing plate form a specific spatial region. When the second connecting part is installed in this region via the hinge shaft, the outer and inner limiting edges restrict the second connecting part from both sides, reducing the risk of swaying during the lifting and lowering of the bed frame and ensuring the safety and stability of the pneumatic bed.

[0010] Preferably, the width of the outer limiting edge is smaller than that of the first side fixing plate, and the outer limiting edge is connected to the first side fixing plate via an inclined edge whose width gradually increases from top to bottom. The inclined edge guides the force to be gradually dispersed and transmitted in a specific direction, efficiently transitioning from the relatively concentrated force-bearing area of ​​the outer limiting edge to the relatively wider force-bearing area of ​​the first side fixing plate, allowing the entire connection structure to bear external forces more evenly. The inclined edge also reinforces the structures of the outer limiting edge and the first side fixing plate, ensuring the strength of the first connection portion.

[0011] Preferably, a second headboard is fixed to the head end of the bed frame. The second headboard is higher than the bed frame, and the second connecting part is fixedly connected to the second headboard. The width of the second headboard is the same as the width of the bed frame, forming a larger connecting surface. The second connecting part can also form a larger connecting surface with the second headboard, improving the stability of the connection between the second connecting part and the bed frame. The second headboard can also shield the hinges, providing the user with a relatively flat headboard.

[0012] Preferably, the second connecting part includes a second fixing plate, and the outer edge of the second fixing plate has a second side fixing plate. The frame includes a headboard frame and a side frame, and the second side fixing plate is fixed to the side frame. The second side fixing plate not only improves the stability of the connection between the second connecting part and the frame, but also makes the connection between the second headboard and the frame more secure.

[0013] Preferably, the second fixing plate has folded edges on both sides, and the upper end of the folded edge is hinged to the first connecting part via a hinge shaft. The folded edge can improve the strength of the second fixing plate, facilitate the hinge connection between the first and second connecting parts, and also allow the folded edge to be more quickly embedded between the outer limiting edge and the inner limiting edge during the slat frame descent.

[0014] Preferably, the first end of the gas spring is hinged to the bed frame at a first hinge position, and the second end of the gas spring is hinged to the slatted frame at a second hinge position.

[0015] Preferably, when the slatted frame is closed, the angle between the gas spring and the slatted frame is greater than 45°; when the slatted frame is open, the angle between the gas spring and the slatted frame is greater than 45°. During the switching between the closed and open states of the slatted frame, the gas spring is perpendicular to the slatted frame. When the gas spring forms a certain angle with the slatted frame, the elastic force of the gas spring can be decomposed into two components: one along the direction of the slatted frame and the other perpendicular to the direction of the slatted frame. The design of an angle greater than 45° allows the component along the direction of the slatted frame to more effectively push or support the movement of the slatted frame, while the component perpendicular to the direction of the slatted frame is relatively small, reducing unnecessary lateral forces. This ensures the smoothness and stability of the slatted frame's movement and also helps to reduce the elastic force requirement of the gas spring, thus lowering costs. The design of the gas spring being perpendicular to the slatted frame makes energy transfer more efficient during the switching process. At this time, the direction of the gas spring's elastic force is more matched with the direction of movement of the slatted frame, which can maximize the conversion of elastic potential energy into the kinetic energy of the slatted frame and reduce energy loss.

[0016] The present invention has the following beneficial effects: When the frame is raised or lowered, due to the special position of the hinge point, the frame rotates around a point higher than its own top. During the upward movement, the frame is no longer significantly restricted by the lower connecting rod as in existing technologies, but rotates around a higher hinge point, allowing the frame to open to a greater extent, making it easier for users to retrieve and place items below the frame.

Detailed Implementation

[0024] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, so as to make the technical solution of this utility model easier to understand and master. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0025] This embodiment provides a pneumatic bed, such as Figure 1-4 As shown, the bed includes a bed frame 100 and a slatted frame 200. The bed frame 100 and the slatted frame 200 are hinged at the head end. The hinge position between the bed frame 100 and the slatted frame 200 is higher than the upper end of the slatted frame 200. A gas spring 300 is provided between the bed frame 100 and the slatted frame 200.

[0026] When the slatted frame 200 is raised or lowered, due to the special position of the hinge point, the slatted frame 200 rotates around a point higher than its own top. During the rising process, the slatted frame 200 is no longer significantly restricted by the lower connecting rod as in existing technologies, but rotates around the higher hinge point, allowing the slatted frame 200 to open to a greater extent, making it easier for users to retrieve and place items below the slatted frame 200.

[0027] like Figure 1-6 As shown, the bed frame 100 and the slatted frame 200 are hinged together by a hinge 400. The hinge 400 includes a first connecting portion fixedly connected to the bed frame 100 and a second connecting portion fixedly connected to the slatted frame 200. The bed frame 100 and the slatted frame 200 are typically made of wood, while the hinge 400 can be made of metal such as stainless steel. The hinge 400 provides a stable and reliable connection between the bed frame 100 and the slatted frame 200. In other alternative embodiments, the bed frame 100 and the slatted frame 200 can also be made of metal, and they can be directly hinged together by a hinge axis.

[0028] like Figure 1-4As shown, the bed frame 100 includes a first headboard 110 and a side panel 120. The first connecting portion includes a first fixing plate 410 fixedly connected to the first headboard 110, and the outer edge of the first fixing plate 410 has a first side fixing plate 420 fixedly connected to the side panel 120. The first fixing plate 410 is fixed to the first headboard 110, establishing the initial connection foundation between the hinge 400 and the headboard portion. The first side fixing plate 420 extends from the outer edge of the first fixing plate 410 and is fixed to the side panel 120. Through this structure, the hinge 400 is tightly connected to both the first headboard 110 and the side panel 120 of the bed frame 100. When the bed frame 200 is raised or lowered, the force is transmitted to the first fixed plate 410 through the hinge 400, and then distributed to the first headboard 110 by the first fixed plate 410. At the same time, the first side fixed plate 420 transmits part of the force to the side plate 120. The overall structure of the bed frame 100 is used to jointly bear and distribute the force, ensuring the stability of the connection. In other optional embodiments, the first connecting part may also be fixedly connected only to the first headboard 110 or the side plate 120.

[0029] Furthermore, the first headboard 110 has a backrest 111 that extends above the side panel 120. The outer edge of the portion of the first fixing plate 410 corresponding to the backrest 111 has an outer limiting edge 411, and the inner edge of the first fixing plate 410 has an inner limiting edge 412. The upper ends of the outer limiting edge 411 and the inner limiting edge 412 are provided with hinge shafts that are hinged to the second connecting part. The second connecting part is located between the outer limiting edge 411 and the inner limiting edge 412. The outer limiting edge 411 and the inner limiting edge 412 on the first fixing plate 410 form a specific spatial area. When the second connecting part is installed in this area through the hinge shaft, the outer limiting edge 411 and the inner limiting edge 412 restrict the second connecting part from both sides, reducing the risk of swaying during the lifting and lowering of the frame 200 and ensuring the safety and stability of the pneumatic bed.

[0030] like Figure 5 , 6As shown, the width of the outer limiting edge 411 is smaller than that of the first side fixing plate 420. The outer limiting edge 411 is connected to the first side fixing plate 420 via an inclined edge 430 whose width gradually increases from top to bottom. The inclined edge 430 can guide the force to be gradually dispersed and transmitted in a specific direction, efficiently transitioning from the relatively concentrated force-bearing area of ​​the outer limiting edge 411 to the relatively wide force-bearing area of ​​the first side fixing plate 420, so that the entire connection structure can bear external forces more evenly. The inclined edge 430 makes the structures of the outer limiting edge 411 and the first side fixing plate 420 mutually reinforce each other, ensuring the strength of the first connection. Since the first side fixing plate 420 is hidden inside the side plate 120, the wider first side fixing plate 420 can improve the connection stability and will not affect the appearance of the pneumatic bed. The narrower outer limiting edge 411 serves as a hinge and reinforcement function while reducing the impact on the appearance of the pneumatic bed. In other alternative embodiments, the widths of the outer limiting edge 411 and the first side fixing plate 420 may also be the same.

[0031] like Figure 1 , 2 As shown, a second headboard 210 is fixed to the head end of the slatted bed frame 200. The second headboard 210 is higher than the slatted bed frame 200, and the second connecting part is fixedly connected to the second headboard 210. The width of the second headboard 210 is the same as the width of the slatted bed frame 200, forming a larger connecting surface. The second connecting part can also form a larger connecting surface with the second headboard 210, improving the stability of the connection between the second connecting part and the slatted bed frame 200. The second headboard 210 can also shield the hinge 400, providing the user with a relatively flat headboard.

[0032] like Figure 5 , 6 As shown, the second connecting part includes a second fixing plate 440, and the outer edge of the second fixing plate 440 has a second side fixing plate 450. The frame 200 includes a headboard frame 220 and a side frame 230, and the second side fixing plate 450 is fixed to the side frame 230. The second side fixing plate 450 not only improves the stability of the connection between the second connecting part and the frame 200, but also makes the connection between the second headboard 210 and the frame 200 more secure.

[0033] like Figure 5 , 6 As shown, the second fixing plate 440 has folded edges 441 on both sides, and the upper end of the folded edge 441 is hinged to the first connecting part through a hinge shaft. The folded edge 441 can improve the strength of the second fixing plate 440, facilitate the hinge of the first connecting part and the second connecting part, and the folded edge 441 can also be embedded more quickly between the outer limiting edge 411 and the inner limiting edge 412 during the descent of the frame 200.

[0034] like Figure 3 , 4 As shown, the first end of the gas spring 300 is hinged to the bed frame 100 at the first hinge position 310, and the second end of the gas spring 300 is hinged to the frame 200 at the second hinge position 320. When the frame 200 is closed, the angle between the gas spring 300 and the frame 200 is greater than 45°, for example, 50° or 60°. When the frame 200 is open, the angle between the gas spring 300 and the frame 200 is greater than 45°, for example, 50° or 60°. During the switching between the closed and open states of the frame 200, the gas spring 300 is perpendicular to the frame 200. When the gas spring 300 forms a certain angle with the frame 200, the elastic force of the gas spring 300 can be decomposed into two components: one along the direction of the frame 200 and the other perpendicular to the direction of the frame 200. The design with an included angle greater than 45° allows the component force along the direction of the slat frame 200 to more effectively push or support its movement, while the component force perpendicular to the direction of the slat frame 200 is relatively small, reducing unnecessary lateral forces. This ensures the smoothness and stability of the slat frame 200's movement and also reduces the elastic force requirement of the gas spring 300, lowering costs. The design of the gas spring 300 being perpendicular to the slat frame 200 makes energy transfer more efficient during switching. At this point, the direction of the gas spring 300's elastic force is more closely matched to the direction of movement of the slat frame 200, maximizing the conversion of elastic potential energy into the kinetic energy of the slat frame 200 and minimizing energy loss.
