[0003] In order to focus on the overall aesthetics and stability, some double-support sofa beds have the bed part tightly connected to the sofa body through built-in slides or folding mechanisms, which cannot be disassembled separately. Therefore, the sofa bed needs to be packaged as a whole to avoid damage to the interior of the sofa bed due to squeezing or collision during transportation. In addition, the sofa bed is usually heavier when folded, which may increase the difficulty of transportation. Utility Model Content

[0004] The utility model discloses a double-support sofa bed that is easy to pack and transport, and aims to solve the technical problems that some double-support sofa beds, in order to focus on overall aesthetics and stability, have their bed portion tightly connected to the sofa body by built-in slide rails or folding mechanisms, and cannot be disassembled separately. Therefore, the sofa bed needs to be packaged as a whole to avoid damage to the interior of the sofa bed due to squeezing or collision during transportation, and the sofa bed is usually heavy when folded, which may increase the difficulty of transportation.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A double-support sofa bed that is easy to pack and transport, comprising a sofa body and a trolley, wherein the sofa body comprises two armrests, a backrest and a base, wherein the base is located between the two armrests, and further comprises:

[0007] Folding mechanism: located on one side of the base;

[0008] Limiting mechanism: located on the inner wall of the opposite side of the base, the limiting mechanism includes two slide rails and a fixed frame, the slide rail is located below the base, and a limiting plate is hinged on the outer wall of one side of the base near the outer walls on both sides. The fixed frame is slidably connected to the inner wall of the slide rail, and two limiting grooves are provided on the inner walls of both sides of the base near the inner wall of one side. Two limiting springs are provided on the inner wall of the limiting groove, and a protrusion is provided at one end of the limiting spring. Limiting columns are provided at both ends of the fixed frame.

[0009] Support mechanism: located on one side of the folding mechanism.

[0010] When the trolley part is folded, the supporting mechanism and the folding mechanism are used to compress and fold the trolley part of the sofa bed. During this period, the limit plate is kept rotating upward. Then, the fixing frame is moved on the slide rail to drive the trolley part to move into the cavity under the base until the operator completely places the trolley part in the cavity. The two limit posts on the fixing frame squeeze the protrusions and the limit springs on both sides and then engage in the limit grooves accordingly. Then, under the reaction force of the two limit springs, the two protrusions are driven to squeeze and limit the limit posts. Then, the limit plate is rotated clockwise to limit the trolley part. This arrangement can quickly realize the folding and storage of the trolley part. According to actual packaging, transportation and handling needs, the limit plate can be rotated in the opposite direction to pull the trolley part outward. At this time, the limit post gradually disengages from the limit groove, and the fixing frame moves along the slide rail until the trolley part can be completely separated from the sofa body, so that it can be disassembled separately, thereby improving the flexibility and convenience of the device and reducing the difficulty of handling for workers.

[0011] In a preferred embodiment, the folding mechanism includes a mounting plate, two mounting rods are provided between the mounting plate and the fixing frame, a support plate is provided on the outer wall of one side of the mounting plate, two universal wheels are provided on the bottom of the mounting plate and the fixing frame, a first connecting rod and a second connecting rod are hingedly connected to the outer wall of one side of the mounting rod, one end of the second connecting rod is hingedly connected to the third connecting rod, and a bed frame is provided on one end of the first connecting rod and one end of the third connecting rod.

[0012] When the sofa bed needs to be fully unfolded, the mounting plate is pulled, and the fixing frame moves in the slide rail. Then the two limit plates are rotated to limit the two ends of the fixing frame. The universal wheels are limited by the locking device. The operator manually pulls up and then pulls the conversion rope horizontally to move the bed frame and the first, second and third connecting rods. Then one end of the bed frame is placed on the support plate. Under the action of the support mechanism, the bed frame is flush with the upper surface of the base, and the sofa bed can be converted into a bed.

[0013] In a preferred solution, the support mechanism includes two support frames, the support frames are hinged to the fixing frame, a support spring is provided on one side outer wall of the mounting rod, one end of the support spring is fixedly connected to the support frame, an oblique groove is provided on one side outer wall of the third connecting rod, the support frame is slidably connected to one side outer wall of the third connecting rod, and the oblique groove is adapted to one end of the support frame.

[0014] When one end of the bed frame is placed on the support plate, the support frame will slide down along the outer wall of the third connecting rod into the inclined groove, thereby providing support and limiting effect on the third connecting rod, thereby providing support for the bed frame. At the same time, under the limitation of the support spring, the support frame always slides on the outer wall of the third connecting rod to prevent the support frame from detaching, which may cause the third connecting rod to lose support and make the bed frame unstable.

[0015] As can be seen from the above, a double-support sofa bed that is easy to pack and transport includes a sofa body and a trolley, wherein the sofa body includes two armrests, a backrest and a base, wherein the base is located between the two armrests, and further includes:

[0024] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application generally described and marked in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work fall within the scope of protection of the present application.

[0025] The double-support sofa bed disclosed in the present invention is convenient for packaging and transportation and is mainly applicable to some double-support sofa beds. In order to focus on the overall aesthetics and stability, the bed portion is tightly connected to the sofa body through a built-in slide rail or a folding mechanism and cannot be disassembled separately. Therefore, the sofa bed needs to be packaged as a whole to avoid damage to the interior of the sofa bed due to squeezing or collision during transportation. In addition, the sofa bed is usually heavy after folding, which may increase the difficulty of transportation.

[0026] Reference Figure 1 、 Figure 2 and Figure 4 A double-support sofa bed that is easy to pack and transport, comprising a sofa body and a trolley, wherein the sofa body comprises two armrests 1, a backrest and a base 3, wherein the base 3 is located between the two armrests 1, and further comprising:

[0027] Folding mechanism: located on one side of the base 3;

[0028] Limiting mechanism: Located on the inner wall of the opposite side of the base 3, the limiting mechanism includes two slide rails 8 and a fixing frame 9. The slide rail 8 is located below the base 3. The outer wall of one side of the base 3 is hingedly connected to the limiting plate 20 near the outer wall on both sides. The fixing frame 9 is slidably connected to the inner wall of the slide rail 8. Two limiting grooves are provided on the inner walls of the two sides of the base 3 near the inner wall on one side. Two limiting springs 17 are provided on the inner walls of the limiting grooves. One end of the limiting spring 17 is provided with a protrusion 18. Both ends of the fixing frame 9 are provided with limiting columns 19;

[0029] Support mechanism: located on one side of the folding mechanism.

[0030] Among them, the limiting groove is a convex structure, and the protrusion 18 is a semicircular structure. The semicircular protrusion 18 can be used in conjunction with the concave parts on both sides of the limiting column 19, while reducing the friction between the limiting column 19.

[0031] Specifically, when the sofa bed needs to be unfolded or folded, the trolley part on the sofa bed is first compressed and folded by the supporting mechanism and the folding mechanism. During this period, the limiting plate 20 is kept rotating upward, and then the fixing frame 9 is moved on the slide rail 8 to drive the trolley part to move into the cavity below the base 3 until the operator completely places the trolley part in the cavity. The two limiting columns 19 on the fixing frame 9 squeeze the protrusions 18 and the limiting springs 17 on both sides and then snap into the limiting grooves accordingly. Then, under the reaction force of the two limiting springs 17, the trolley part is driven to move downward. The two protrusions 18 squeeze and limit the limiting column 19, and then the limiting plate 20 is rotated 90 degrees clockwise to limit the trolley part. This arrangement can quickly realize the folding and storage of the trolley part. According to the actual packaging, transportation and handling needs, the limiting plate 20 can be rotated 90 degrees in the opposite direction to pull the trolley part outward. At this time, the limiting column 19 gradually disengages from the limiting groove, and the fixing frame 9 moves along the slide rail 8 until the trolley part can be completely separated from the sofa body, realizing separate disassembly, improving the flexibility and convenience of the device, and reducing the difficulty of workers' handling.

[0032] Reference Figure 1 and Figure 3 In a preferred embodiment, the folding mechanism includes a mounting plate 2, two mounting rods 6 are provided between the mounting plate 2 and the fixing frame 9, a support plate 10 is provided on the outer wall of one side of the mounting plate 2, and two universal wheels 7 are provided at the bottom of the mounting plate 2 and the fixing frame 9. A first connecting rod 11 and a second connecting rod 12 are hingedly connected to the outer wall of one side of the mounting rod 6, and a third connecting rod 13 is hingedly connected to one end of the second connecting rod 12. A bed frame 5 is provided at one end of the first connecting rod 11 and one end of the third connecting rod 13.

[0033] It should be noted that, during use, the universal wheel 7 may be equipped with a locking device, such as a ground brake or other existing equipment, which is not shown in the drawings.

[0034] Among them, two conversion ropes 16 are provided on the outer wall of one side of the bed frame 5. Pulling them can change the structure of the sofa bed, thereby realizing the conversion from sofa to bed or from bed to sofa.

[0035] Specifically, when the sofa bed needs to be fully unfolded, the mounting plate 2 is pulled, and the fixing frame 9 moves in the slide rail 8. Then the two limit plates 20 are rotated to limit the two ends of the fixing frame 9. The universal wheel 7 is limited by the locking device. The operator manually pulls up and then pulls the conversion rope 16 horizontally to move the bed frame 5 and the first connecting rod 11, the second connecting rod 12 and the third connecting rod 13. Then, one end of the bed frame 5 is placed on the support plate 10. Under the action of the support mechanism, the bed frame 5 is flush with the upper surface of the base 3, and the sofa bed can be converted into a bed.

[0036] Reference Figure 1 and Figure 3 In a preferred embodiment, the support mechanism includes two support frames 15, which are hinged to the fixing frame 9. A support spring 14 is provided on one side outer wall of the mounting rod 6, and one end of the support spring 14 is fixedly connected to the support frame 15. An oblique groove is provided on one side outer wall of the third connecting rod 13, and the support frame 15 is slidably connected to one side outer wall of the third connecting rod 13, and the oblique groove is adapted to one end of the support frame 15.

[0037] The fixing frame 9 is a concave structure, which is used in conjunction with the mounting plate 2 and the two mounting rods 6 to increase the stability of the trolley when it moves.

[0038] Specifically, when one end of the bed frame 5 is placed on the support plate 10, the support frame 15 will slide down along the outer wall of the third connecting rod 13 into the inclined groove, thereby providing support and limiting effect on the third connecting rod 13, thereby providing support for the bed frame 5. At the same time, under the limitation of the support spring 14, the support frame 15 always slides on the outer wall of the third connecting rod 13 to prevent the support frame 15 from detaching, which may cause the third connecting rod 13 to lose support and the bed frame 5 to become unstable.

[0039] Reference Figure 1 and Figure 2 In a preferred embodiment, storage cavities are provided on the top outer walls of the two armrests 1, a mounting cover 4 is hinged on the top of the armrest 1, and a cup holder is provided on the top outer wall of the mounting cover 4. This arrangement improves the user experience, maximizes the use of space, achieves a multi-purpose effect, and increases the practicality of the device.

[0040] Working principle: When the sofa bed needs to be converted from a bed form to a sofa form for packaging and transportation, the trolley part of the sofa bed is first compressed and folded by the supporting mechanism and the folding mechanism. During this period, the limit plate 20 is kept rotating upwards. Then, the fixing frame 9 is moved on the slide rail 8, thereby driving the trolley part to move into the cavity below the base 3 until the operator completely places the trolley part in the cavity. The two limit columns 19 on the fixing frame 9 squeeze the protrusions 18 and the limit springs 17 to the sides and then snap into the limit grooves accordingly. Then, under the reverse action of the two limit springs 17, the trolley part is moved back and forth. Under the force, the two protrusions 18 are driven to squeeze and limit the limit column 19, and then the limit plate 20 is rotated 90 degrees clockwise to limit the trolley part. This arrangement can quickly realize the folding and storage of the trolley part. It can also be used according to the actual packaging, transportation and handling needs. The limit plate 20 is rotated 90 degrees in the opposite direction to pull the trolley part outward. At this time, the limit column 19 gradually disengages from the limit groove, and the fixing frame 9 moves along the slide rail 8 until the trolley part can be completely separated from the sofa body, realizing separate disassembly, improving the flexibility and convenience of the device, and reducing the difficulty of workers' handling.
