Description

Technical Field

[0001] This utility model relates to a bed structure, specifically a bed structure with an adjustable lying angle. Background Technology

[0002] In business venues such as hotels, each room needs to be equipped with one or two beds for people to rest.

[0003] Existing bed designs in commercial spaces are often flawed, complex, and fixed in shape, unable to be altered or adjusted. This limits their applicability to users who wish to change their lying angle. Furthermore, the existing bed boards are often one-piece designs, and since different parts of the body feel different pressure points on the board, some areas experience excessive pressure while others feel insufficient pressure. This prevents the bed board from making close contact with different parts of the body, resulting in a poor lying experience. Therefore, the inventor has improved the bed structure. Utility Model Content

[0004] The purpose of this utility model is to provide a bed structure with an adjustable lying angle. This bed structure has the advantages of simple structure, reasonable design, ability to change various lying angles, suitability for different user needs, improved applicability, closer contact with various parts of the user's body, support for different parts of the user's body, smaller pressure differences between different parts of the user's body, better comfort, and a better lying experience. It solves the problems mentioned in the above-mentioned technical background.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bed structure with an adjustable reclining angle, comprising a U-shaped bed frame and a bed board disposed above the bed frame. A drive mechanism is provided between the bed frame and the bed board. The drive mechanism includes a support base and two side rods symmetrically disposed at both ends of the support base. Both side rods are fixed to the support base, and an electric cylinder and a central shaft located above the electric cylinder are disposed between the two side rods. The electric cylinder and the central shaft are connected by a connecting seat, and the end of the electric cylinder away from the connecting seat is connected to the support base. Both ends of the central shaft are rotatably connected to the two side rods, and both ends of the central shaft are fixedly connected to a receiving rod. Each receiving rod is equipped with an upper wheel and a lower wheel located below the upper wheel.

[0006] Preferably, both support seats are vertically arranged and both support seats are fixed to the inside of the bed frame.

[0007] Preferably, the two receiving rods are arranged in parallel, and the receiving rod includes an upper rod body and a lower rod body disposed below the upper rod body. The upper rod body and the lower rod body are connected by a bending part, and the included angle between the upper rod body and the lower rod body is between 165° and 175°.

[0008] Preferably, a groove is provided through the limiting strip, and the positioning block passes through the groove and is fixed on the support base.

[0009] Preferably, there are two sets of drive mechanisms, which are distributed at both ends of the bed frame. The bed board includes two main boards and a central board between the two main boards. The two main boards are respectively fixed to the side rods of the two sets of drive mechanisms, and the main boards and the central board are connected by hinges.

[0010] Preferably, the main body includes a base, and two symmetrically distributed contact plates are fixed on the lower end face of the base. The base is a hollow cavity structure with an opening at one end. A bladder and a main gasket located above the bladder are disposed inside the cavity. The bladder includes a pressure-bearing bladder and floating bladders respectively disposed at both ends of the pressure-bearing bladder. The bladder is a hollow cavity structure.

[0011] Preferably, the main pad includes a central pad and edge pads fixed to both ends of the central pad. The central pad is fixed to the upper end face of the pressure bladder, and the edge pads are fixed to the upper end face of the buoyancy bladder.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model provides a bed structure with adjustable reclining angle. The adjustable reclining angle bed structure includes a U-shaped bed frame and a bed board positioned above the bed frame. Two sets of drive mechanisms are arranged between the bed frame and the bed board. The overall structure is simple and rationally designed. The bed board includes two main body panels and a central plate positioned between the two main body panels. The drive mechanism includes two parallel support seats, with a drive assembly between the two support seats. The drive assembly includes an electric cylinder and an active transmission rod rotatably connected to the telescopic end of the electric cylinder. The end of the electric cylinder furthest from the active transmission rod is rotatably connected to the support seat. The bottom of the active transmission rod has a bending rod and a limiting strip located on one side of the bending rod. The bending rod is fixedly connected to the active transmission rod and rotatably connected to the support seat. The limiting strip is rotatably connected to the active transmission rod. The two sets of drive mechanisms drive the two main body panels to rotate, causing the central plate to rotate accordingly, tilting the two main body panels and the two central plate to a specified angle, thus achieving various reclining angle changes. This caters to the needs of different users, expands its applicability, and is suitable for widespread use.

[0014] 2. The main body of this utility model includes a base, which is a hollow cavity structure with an opening at one end. A bladder and a main pad located above the bladder are disposed within this cavity. The bladder includes a pressure-bearing bladder and floating bladders respectively disposed at both ends of the pressure-bearing bladder. The bladder is a hollow cavity structure. When a person lies on the bed board and presses against the bladder, the pressure on the pressure-bearing bladder will squeeze the air into the floating bladders on both sides. Specifically, the base is fixed to the upper end face of the top mounting rod. When the user lies down, their body presses against the two bases, generating pressure on the two pressure-bearing bladders. At this time, the air inside the bladder rushes into the floating bladders on both sides, creating pressure between the floating bladders and the user's body, thus providing a massage effect. It can also fill the gap between the user's body and the base, making the base more closely contacted with various parts of the user's body, supporting different parts of the user's body, and minimizing the pressure difference between different parts of the user's body, thereby providing a better sensation and enhancing the user's lying-down experience.

Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0024] Please see Figure 1 One embodiment of this utility model is a bed structure with an adjustable lying angle. The bed structure includes a U-shaped bed frame 1 and a bed board 2 disposed above the bed frame 1. A drive mechanism 3 is disposed between the bed frame 1 and the bed board 2. There are two sets of drive mechanisms 3, and the two sets of drive mechanisms 3 are distributed at both ends of the bed frame 1.

[0025] Please see Figure 2The bed board 2 includes two main boards 21 and a plurality of center boards 22 disposed between the two main boards 21. Each of the two main boards 21 is connected to one of the center boards 22 by a hinge 23. In this embodiment, there are three center boards 22, which are distributed between the two main boards 21. Adjacent center boards 22 are also connected by hinges 23. A secondary gasket 24 is fixedly bonded to the upper end surface of the center board 22.

[0026] Please see Figure 3 The main body 21 includes a base 211, which is a hollow cavity structure with an opening at one end. A bladder 212 and a main gasket 213 located above the bladder 212 are disposed within this cavity. The bladder 212 includes a pressure-bearing bladder 2121 and floating bladders 2122 respectively disposed at both ends of the pressure-bearing bladder 2121. The pressure value within the cavity of the bladder 212 is greater than or equal to one standard atmosphere, specifically 1 to 1.06 times one standard atmosphere. When a person lies on the bed board 2 and presses against the bladder 212, the pressure-bearing bladder 2121 is compressed, forcing air into the floating bladders 2122 on both sides. The main gasket 213 includes a central gasket 2131 and gaskets fixed to the central gasket 2131. The edge pads 2132 at both ends and the center pad 2131 are fixed to the upper surface of the pressure bladder 2121, while the edge pads 2132 are fixed to the upper surface of the floating bladder 2122. When the user lies on the bed structure, their body presses on the two base plates 211, which in turn exerts pressure on the two pressure bladders 2121. At this time, the air inside the bladder 212 rushes into the floating bladders 2122 on both sides, creating a certain pressure between the floating bladders 2122 and the user's body, thus providing a massage effect. It can also fill the gap between the user's body and the base plate 211, making the base plate 211 more closely contact with various parts of the user's body, supporting different parts of the user's body, reducing the pressure difference between different parts of the user's body, and providing a better feeling and improving the user's lying experience.

[0027] Please see Figure 4 Two symmetrically distributed contact plates 214 are fixed on the lower end face of the plate base 211.

[0028] Please see Figure 5The drive mechanism 3 includes a support base 31 and two side rods 32 symmetrically arranged at both ends of the support base 31. A plate base 211 is fixed to the upper surface of the two side rods 32. Both support bases 31 are vertically arranged and fixed to the inner side of the bed frame 1. Both side rods 32 are fixed to the support bases 31. An electric cylinder 33 and a central shaft 34 located above the electric cylinder 33 are arranged between the two side rods 32. The electric cylinder 33 and the central shaft 34 are connected via a connecting seat 35. The end of the electric cylinder 33 away from the connecting seat 35 is connected to the support base 31. Both ends of the central shaft 34 are rotatably connected to the two side rods 32, and both ends of the central shaft 34 are fixedly connected to a receiving rod 36. Each receiving rod 36 is equipped with an upper wheel body 37 and a lower wheel body 38 located below the upper wheel body 37. The two receiving rods 36 are arranged in parallel, and each receiving rod 36 includes an upper rod body 361. The upper rod 361 is located below the lower rod 362. The upper rod 361 and the lower rod 362 are connected by a bending part 363, and the included angle between the upper rod 361 and the lower rod 362 is between 165° and 175°. During the process of the electric cylinder 33 driving the connecting seat 35 to rise, the connecting seat 35 flips with the electric cylinder 33, and drives the two receiving rods 36 to flip as well. Finally, the lower rod 362 is brought close to the contact plate 214, and the lower wheel 38 on the lower rod 362 directly contacts the contact plate 214, which reduces the friction and provides good protection for the main plate 21. At this time, the main plate 21 will flip to a certain angle under the drive of the electric cylinder 33, and the bending part 363 is just located in the area between the main plate 21 and the center plate 22, so that the receiving rods 36 as a whole will not conflict with the center plate 22.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
