Description

Technical Field

[0001] This application relates to the field of folding bed technology, and more particularly to a folding bed. Background Technology

[0002] As people's demands for quality of life increase, folding beds are being used more and more widely in various scenarios. A folding bed unfolds to provide a place to lie down, and can be folded up and stored in a cabinet after use. To ensure user comfort, folding beds are usually designed with a large unfolded area. However, a larger unfolded area also means a larger space required for storage, resulting in poor portability and a large storage space requirement. Utility Model Content

[0003] This application provides a folding bed that solves the technical problem that when the unfolded area of ​​the folding bed is large, the space occupied when the folding bed is stored will also increase, resulting in poor portability and a large amount of storage space occupied by the folding bed.

[0004] To achieve the above objectives, the main technical solutions adopted in this application include:

[0005] This application provides a folding bed, which includes a first fixed frame, a first bed body, and a second bed body. The first fixed frame includes a first fixed block and a second fixed block, which are arranged opposite to and spaced apart along a first direction, which is perpendicular to the vertical direction. The first bed body is rotatably disposed on the first fixed block and the second fixed block, and the rotation axis of the first bed body is parallel to the first direction. The second bed body is rotatably disposed on the first fixed block and the second fixed block, and the rotation axis of the second bed body is parallel to the first direction. The first bed body includes two relatively rotatable first sub-bed bodies, and the second bed body includes two relatively rotatable second sub-bed bodies. The rotation axes of the first sub-bed bodies and the rotation axes of the second sub-bed bodies are both parallel to the first direction.

[0006] This application proposes a folding bed. The first bed frame includes two relatively rotatable first sub-bed frames, and the second bed frame includes two relatively rotatable second sub-bed frames. When folded, the plane containing the largest cross-sections of the two first and two second sub-bed frames is parallel to the vertical plane, reducing the volume of the first bed frame when folded and minimizing its space occupation in storage cabinets or boxes. The two first and two second sub-bed frames increase the unfolded area of ​​the folding bed, increasing the area available to the user and allowing for a more comfortable lying position. Furthermore, because the first bed frame includes two first sub-bed frames and the second bed frame includes two second sub-bed frames, the folding bed occupies less space when folded, significantly reducing storage space required for the same unfolded area.

[0007] Optionally, the first bed body further includes a second fixing frame, which includes a third fixing block and a fourth fixing block. Along the first direction, the third fixing block and the fourth fixing block are opposite to each other and spaced apart. Each first sub-bed body is rotatably mounted on the third fixing block and the fourth fixing block. The second bed body further includes a third fixing frame, which includes a fifth fixing block and a sixth fixing block. Along the first direction, the fifth fixing block and the sixth fixing block are opposite to each other and spaced apart. Each second sub-bed body is rotatably mounted on the fifth fixing block and the sixth fixing block.

[0008] Each sub-bed can be rotatably mounted between corresponding fixed blocks. This design makes the folding bed smoother when folding and unfolding, reducing the user's operating difficulty and time, and making it easy to carry and store.

[0009] Optionally, the folding bed also includes a fourth fixing frame and a fifth fixing frame. The first sub-bed, furthest from the second bed, is rotatably mounted on the fourth fixing frame, and the second sub-bed, furthest from the first bed, is rotatably mounted on the fifth fixing frame. The first fixing frame is equipped with a first set of wheels, the fourth fixing frame is equipped with a second set of wheels, and the fifth fixing frame is equipped with a third set of wheels.

[0010] By adding a fourth and fifth fixing frame, additional support points are provided for the first sub-bed unit furthest from the second bed unit and the second sub-bed unit furthest from the first bed unit. This multi-point support design makes the overall structure of the folding bed more stable and further improves its load-bearing capacity. When the folding bed is unfolded and in use, the pressure is shared by each sub-bed unit and the fixing frame, avoiding excessive stress on a single point and thus extending the service life of the folding bed.

[0011] Optionally, there are two first wheel groups, which are respectively disposed on the first fixed block and the second fixed block. Each first wheel group includes multiple first wheels arranged in sequence along the second direction, and the first direction, the second direction and the vertical direction are perpendicular to each other. There are two second wheel groups, which are respectively disposed at both ends of the fourth fixed frame along the first direction. Each second wheel group includes multiple second wheels arranged in sequence along the second direction. There are two third wheel groups, which are respectively disposed at both ends of the fifth fixed frame along the first direction. Each third wheel group includes multiple third wheels arranged in sequence along the second direction.

[0012] The first, second, and third wheel sets are located at both ends along the first direction, and each wheel set includes multiple wheels arranged sequentially along the second direction. This layout helps prevent the folding bed from tipping over or wobbling when subjected to force, thus improving safety during use.

[0013] Optionally, the first, second, and third wheels are all omnidirectional wheels.

[0014] Omnidirectional wheels offer three degrees of freedom in a plane (forward and backward movement, left and right movement, and rotation in place), making the folding bed more flexible and convenient to move. Users can move the folding bed in any direction using a combination of omnidirectional wheel movements without changing its orientation. This design greatly simplifies the packing process and improves ease of use.

[0015] Optionally, each of the adjacent first and second sub-beds is provided with a clearance portion at the end closest to each other, so as to avoid each other when the adjacent first and second sub-beds are stacked.

[0016] The avoidance design allows adjacent first and second sub-bed units to smoothly avoid each other when stacked, preventing folding difficulties caused by structural interference. This not only improves the folding efficiency of the folding bed but also makes operation easier and more convenient for users. The avoidance design also enables the folding bed to form a more compact structure, thus making more efficient use of storage space. This is especially important in spaces with limited capacity, such as homes and offices, as it saves valuable space resources.

[0017] Optionally, each first sub-bed includes a first frame and a first mattress disposed on the first frame, and each second sub-bed includes a second frame and a second mattress disposed on the second frame; the first frame includes a first annular frame and a plurality of first crossbeams connected to the first annular frame, the plurality of first crossbeams being spaced apart along a first direction, and the second frame includes a second annular frame and a plurality of second crossbeams connected to the second annular frame, the plurality of second crossbeams being spaced apart along the first direction.

[0018] The first and second mattresses are respectively positioned on the first and second frames. Thanks to the stability of the frames, the mattresses receive ample support and are less prone to deformation or sagging. This design also ensures a close fit between the mattress and the bed frame, reducing friction and noise and improving comfort.

[0019] Optionally, the first fixing frame further includes a first connecting beam, which connects the first fixing block and the second fixing block; the second fixing frame further includes a second connecting beam, which connects the third fixing block and the fourth fixing block; the folding bed further includes a first connecting rod and a first hydraulic rod, with the two ends of the first connecting rod hinged to the first connecting beam and the second connecting beam respectively in the length direction; the first hydraulic rod includes a first cylinder and a first piston rod, with the first cylinder hinged to the first connecting rod, one end of the first piston rod slidingly disposed within the first cylinder in the length direction, and the other end of the first piston rod hinged to the first beam; the third fixing frame further includes a third connecting beam, which connects the fifth fixing block and the sixth fixing block; the folding bed further includes a second connecting rod and a second hydraulic rod, with the two ends of the second connecting rod hinged to the first connecting beam and the third connecting beam respectively in the length direction; the second hydraulic rod includes a second cylinder and a second piston rod, with the second cylinder hinged to the second connecting rod, one end of the second piston rod slidingly disposed within the second cylinder in the length direction, and the other end of the second piston rod hinged to the second beam in the length direction.

[0020] The design of the first and second hydraulic rods not only provides folding and unfolding functionality but also enhances the bed's support strength when bearing weight. Furthermore, the design of the first and second connecting rods allows the folding bed to be easily folded and unfolded, facilitating user operation in various scenarios.

[0021] Optionally, the folding bed further includes a first limiting rod, one end of which is hinged to a first crossbeam. The first limiting rod has a first elongated hole, the length direction of which is parallel to the length direction of the first limiting rod. The end of the first connecting rod that is hinged to the first connecting crossbeam is slidably engaged in the first elongated hole. The folding bed further includes a second limiting rod, one end of which is hinged to a second crossbeam. The second limiting rod has a second elongated hole, the length direction of which is parallel to the length direction of the second limiting rod. The end of the second connecting rod that is hinged to the first connecting crossbeam is slidably engaged in the second elongated hole.

[0022] The design of the first and second elongated holes not only allows the first and second connecting rods to slide within a certain range, but also prevents them from detaching. Even if a large external impact is encountered during use, the first and second connecting rods can be effectively confined within the elongated holes, reducing the probability of danger caused by their detachment.

[0023] Optionally, the folding bed further includes a first support rod, with its two ends in the length direction hinged to a fourth fixed frame and a second connecting beam, respectively; the folding bed also includes a second support rod, with its two ends in the length direction hinged to a fifth fixed frame and a third connecting beam, respectively.

[0024] The two ends of the first support rod along its length are hinged to the fourth fixed frame and the second connecting beam, respectively, while the two ends of the second support rod along its length are hinged to the fifth fixed frame and the third connecting beam, respectively. This hinged connection method allows the folding bed to form a stable support structure when unfolded. The hinged connection between the support rods and the fixed frames and connecting beams allows for a certain degree of movement during folding and unfolding, while providing sufficient support force in the use state to ensure the stability and safety of the folding bed.

[0059] As people's demands for quality of life increase, folding beds are being used more and more widely in various scenarios. As a simple bed designed using the principle of joints, the folding bed has a folding and unfolding function, designed to be convenient to use and save space. Folding beds are widely used in outdoor, office lunch break, and temporary home use scenarios.

[0060] When in use, a folding bed is unfolded to its maximum size, providing ample space for a person to lie down. The larger the unfolded area, the greater the user's comfort. After use, the folding bed can be stored away in a cabinet. As more people use folding beds, and given that many office workers need to take lunch breaks, and office storage space is typically limited to conserve resources, this limited storage space becomes a contradiction with the increasing number of folding beds. Furthermore, for users to comfortably use a folding bed, the bed board must have a sufficiently large unfolded area.

[0061] However, when the unfolded area of ​​a folding bed is large, the space it occupies when folded up will also increase, resulting in poor portability and a large amount of storage space required.

[0062] In view of this, in order to solve the technical problems that when the unfolded area of ​​a folding bed is large, the space occupied when the folding bed is stored will also be large, resulting in poor portability and large storage space occupation, this application proposes a folding bed, which includes a first fixed frame, a first bed body and a second bed body.

[0063] The first fixed frame includes a first fixed block and a second fixed block, which are arranged opposite to and spaced apart along a first direction, which is perpendicular to the vertical direction. A first bed body is rotatably mounted on the first and second fixed blocks, and the rotation axis of the first bed body is parallel to the first direction. A second bed body is rotatably mounted on the first and second fixed blocks, and the rotation axis of the second bed body is parallel to the first direction. The first bed body includes two relatively rotatable first sub-bed bodies, and the second bed body includes two relatively rotatable second sub-bed bodies. The rotation axes of the first and second sub-bed bodies are both parallel to the first direction.

[0064] In the above design, the first bed frame includes two relatively rotatable first sub-bed frames, and the second bed frame includes two relatively rotatable second sub-bed frames. When folded, the plane containing the largest cross-sections of the two first and two second sub-bed frames is parallel to the vertical plane, reducing the volume of the first bed frame when folded and minimizing its space occupation in storage cabinets or boxes. The two first and two second sub-bed frames increase the unfolded area of ​​the folding bed, increasing the area available to the user and allowing for a more comfortable lying position. Furthermore, because the first bed frame includes two first sub-bed frames and the second bed frame includes two second sub-bed frames, the folding bed occupies less space when folded, significantly reducing storage space requirements, while maintaining the same unfolded area.

[0065] For ease of explanation, the following embodiments use a folding bed as an example.

[0066] Figure 1 This is a schematic diagram of the folding bed in its unfolded state, as provided in an embodiment of this application. Figure 2 This is a schematic diagram of the folding bed provided in the embodiments of this application during the folding process; Figure 3 for Figure 2 Side view; Figure 4 This is a schematic diagram of the folding bed provided in the embodiments of this application in its folded state; Figure 5 The structures of the first and second frames are shown; Figure 6 for Figure 5 Side view; Figure 7 The structure of the first sunshade is shown.

[0067] Please refer to Figures 1 to 6 In this embodiment, the folding bed 100 includes a first fixing frame 110, a first bed body 120, and a second bed body 130. The first fixing frame 110 includes a first fixing block 111 and a second fixing block 112. Along the first direction X, the first fixing block 111 and the second fixing block 112 are arranged opposite to each other and spaced apart. The first direction X is perpendicular to the vertical direction Z. The first bed body 120 is rotatably disposed on the first fixing block 111 and the second fixing block 112. The rotation axis of the first bed body 120 is parallel to the first direction X. The second bed body 130 is rotatably disposed on the first fixing block 111 and the second fixing block 112. The rotation axis of the second bed body 130 is parallel to the first direction X. The first bed body 120 includes two relatively rotatable first sub-bed bodies 121, and the second bed body 130 includes two relatively rotatable second sub-bed bodies 131. The rotation axes of the first sub-bed bodies 121 and the rotation axes of the second sub-bed bodies 131 are both parallel to the first direction X.

[0068] The first fixing block 111 and the second fixing block 112 are used to fix the first bed body 120 and the second bed body 130. The projections of the first fixing block 111 and the second fixing block 112 on the first direction X coincide. Along the first direction X, the first bed body 120 and the second bed body 130 are disposed between the first fixing block 111 and the second fixing block 112. The first bed body 120 is rotatably disposed on the first fixing block 111 and the second fixing block 112, that is, the first bed body 120 can rotate relative to the first fixing block 111 and the second fixing block 112. The rotation axis of the first bed body 120 is parallel to the first direction X, and the first bed board can rotate around the first direction X. Similarly, the rotation axis of the second bed body 130 is parallel to the first direction X, and the second bed body 130 can rotate around the first direction X.

[0069] When the folding bed 100 needs to be unfolded for use, the maximum cross-section of the first bed body 120 and the second bed body 130 is parallel to the vertical direction Z and the second direction Y. The first direction X, the second direction Y and the vertical direction Z are perpendicular to each other. When the folding bed 100 is in the storage or folded state, the plane containing the maximum cross-section of the first bed body 120 and the second bed body 130 is perpendicular to the vertical direction Z.

[0070] The first bed 120 can be composed of two relatively rotatable first sub-beds 121, and the second bed 130 can also be composed of two relatively rotatable second sub-beds 131. That is to say, the two first sub-beds 121 can rotate relative to each other, and the two second sub-beds 131 can also rotate relative to each other. It can be understood that the two first sub-beds 121 can rotate relative to the two second sub-beds 131 respectively.

[0071] When the folding bed 100 needs to be stowed, the projections of the maximum cross-sections of the two first sub-bed bodies 121 and the two second sub-bed bodies 131 coincide along the second direction Y, and the plane containing the maximum cross-sections of the two first sub-bed bodies 121 and the two second sub-bed bodies 131 is perpendicular to the second direction Y. When the folding bed 100 is unfolded, the planes containing the maximum cross-sections of the two first sub-bed bodies 121 and the two second sub-bed bodies 131 are both perpendicular to the vertical direction Z.

[0072] The first bed frame 120 includes two relatively rotatable first sub-bed frames 121, and the second bed frame 130 includes two relatively rotatable second sub-bed frames 131. When folded, the plane containing the largest cross-sections of the two first sub-bed frames 121 and the two second sub-bed frames 131 is parallel to the vertical plane, reducing the volume of the first bed frame 120 when folded and minimizing its space occupation in storage cabinets or boxes. The arrangement of the two first sub-bed frames 121 and the two second sub-bed frames 131 increases the unfolded area of ​​the folding bed 100, increasing the area available to the user and allowing for a more comfortable lying position. Furthermore, because the first bed frame 120 includes two first sub-bed frames 121 and the second bed frame 130 includes two second sub-bed frames 131, the folding bed 100 occupies less space when folded, significantly reducing its storage space.

[0073] Please refer to Figures 1 to 6 In this embodiment, the first bed body 120 further includes a second fixing frame 140, which includes a third fixing block 141 and a fourth fixing block 142. Along the first direction X, the third fixing block 141 and the fourth fixing block 142 are arranged opposite to each other and spaced apart. Each first sub-bed body 121 is rotatably disposed on the third fixing block 141 and the fourth fixing block 142. The second bed body 130 further includes a third fixing frame 150, which includes a fifth fixing block 151 and a sixth fixing block 152. Along the first direction X, the fifth fixing block 151 and the sixth fixing block 152 are arranged opposite to each other and spaced apart. Each second sub-bed body 131 is rotatably disposed on the fifth fixing block 151 and the sixth fixing block 152.

[0074] In the first direction X, the projections of the third fixing frame 150 and the fourth fixing frame 160 can coincide. Each first sub-bed 121 is rotatably mounted on the third fixing block 141 and the fourth fixing block 142. For example, each first sub-bed 121 can be hingedly mounted on the third fixing block 141 and the fourth fixing block 142. The hinged connection allows the two first sub-beds 121 to rotate or swing flexibly relative to each other. Compared with other connection methods, the hinged connection requires less space, which allows the product to maintain good functionality and aesthetics while being compactly designed. Especially when it is necessary to control the size of the folding bed 100, the hinged connection can greatly reduce the space occupied by the folding bed 100. The manufacturing process of the hinged connection is mature, and the hinge structure is simple, which makes the connection highly reliable. Under normal use, the service life of the hinged connection is also relatively long, reducing failures and maintenance costs caused by connection failure. Moreover, the maintenance of the hinged connection is relatively simple, usually only the damaged hinge part needs to be replaced. This easy maintenance feature reduces the maintenance cost of the product and also improves the overall service life of the product.

[0075] Along the first direction X, two first sub-bed bodies 121 are positioned between the third fixing block 141 and the fourth fixing block 142. When the folding bed 100 needs to be folded, along the second direction Y, the projections of the maximum cross-sections of the two first sub-bed bodies 121 coincide. Similarly, when the folding bed 100 is folded, along the first direction X, the projections of the maximum cross-sections of the two second sub-bed bodies 131 coincide.

[0076] By setting the second fixing frame 140 and the third fixing frame 150 to fix the first sub-bed 121 and the second sub-bed 131 respectively, the overall connection strength of the bed can be significantly improved, making the folding bed 100 more stable when unfolded or folded, and less prone to shaking or deformation. Due to the setting of the third fixing block 141, the fourth fixing block 142, the fifth fixing block 151 and the sixth fixing block 152, they jointly support each sub-bed, thereby improving the load-bearing capacity of the folding bed 100 and making it more stable and safer for users during use.

[0077] Each sub-bed can be rotatably positioned between corresponding fixed blocks. This design makes the folding bed 100 smoother when folding and unfolding, reducing the user's operating difficulty and time, and making it easy to carry and store.

[0078] Please refer to Figures 1 to 6In this embodiment, the folding bed 100 further includes a fourth fixing frame 160 and a fifth fixing frame 170. The first sub-bed 121, furthest from the second bed 130, is rotatably mounted on the fourth fixing frame 160, and the second sub-bed 131, furthest from the first bed 120, is rotatably mounted on the fifth fixing frame 170. The first fixing frame 110 is provided with a first wheel set 113, the fourth fixing frame 160 is provided with a second wheel set 161, and the fifth fixing frame 170 is provided with a third wheel set 171.

[0079] The fourth fixing frame 160 and the fifth fixing frame 170 are respectively located at both ends of the folding bed 100. There are two first sub-bed bodies 121, with the first sub-bed body 121 furthest from the second sub-bed body 131 rotatably mounted on the fourth fixing frame 160. There are also two second sub-bed bodies 131, with the second sub-bed body 131 furthest from the first sub-bed body 121 rotatably mounted on the fifth fixing frame 170.

[0080] By adding a fourth fixing frame 160 and a fifth fixing frame 170, additional support points are provided for the first sub-bed 121, which is furthest from the second bed 130, and the second sub-bed 131, which is furthest from the first bed 120. This multi-point support design makes the overall structure of the folding bed 100 more stable and further improves its load-bearing capacity. When the folding bed 100 is unfolded and in use, the pressure is shared by each sub-bed and the fixing frame, avoiding excessive stress on a single point, thereby extending the service life of the folding bed 100.

[0081] The arrangement of the first wheel group 113, the second wheel group 161, and the third wheel group 171 makes the folding bed 100 fold more smoothly, reducing the difficulty and time required for user operation. Simultaneously, the rolling characteristics of the first wheel group 113, the second wheel group 161, and the third wheel group 171 also make it easier for users to move the folding bed 100. The folding bed 100 is compact in size when folded, and with the addition of the wheels, users can easily push it to a corner or storage room for storage, greatly reducing its space occupation. The addition of the wheels also makes the folding bed 100 more convenient to transport, allowing users to easily push it onto vehicles for movement.

[0082] For example, the folding bed 100 may also include multiple first braking components, and omnidirectional wheel sets may be provided on the second fixing frame 140 and the third fixing frame 150. The multiple first braking components are respectively connected to the first wheel set 113, the second wheel set 161, the third wheel set 171, and the omnidirectional wheel set. On the one hand, the folding bed 100 can move through the wheel sets when it is unfolded. On the other hand, when the user needs to move the folding bed 100, they can directly push the folding bed 100 in the unfolded state, improving user efficiency and providing a better user experience. When the user needs to unfold the folding bed 100 to rest, the first braking components can be used to brake the folding bed 100 to prevent it from sliding.

[0083] Please refer to Figures 1 to 6 In this embodiment, there are two first wheel groups 113, which are respectively disposed on the first fixing block 111 and the second fixing block 112. Each first wheel group 113 includes multiple first wheels 114 arranged sequentially along the second direction Y. The first direction X, the second direction Y and the vertical direction Z are perpendicular to each other. There are two second wheel groups 161, which are respectively disposed at both ends of the fourth fixing frame 160 along the first direction X. Each second wheel group 161 includes multiple second wheels 162 arranged sequentially along the second direction Y. There are two third wheel groups 171, which are respectively disposed at both ends of the fifth fixing frame 170 along the first direction X. Each third wheel group 171 includes multiple third wheels 172 arranged sequentially along the second direction Y.

[0084] The first wheel group 113 is respectively disposed on the first fixing block 111 and the second fixing block 112, and each first wheel group 113 includes multiple first wheels 114 arranged sequentially along the second direction Y. This design allows the folding bed 100 to distribute pressure more evenly when unfolded, improving the stability of the overall structure. At the same time, the second wheel group 161 and the third wheel group 171 are disposed in the same way, providing additional support points for the folding bed 100 and further enhancing its load-bearing capacity.

[0085] The first wheel group 113, the second wheel group 161 and the third wheel group 171 are provided at both ends along the first direction X, and each wheel group includes multiple wheels arranged sequentially along the second direction Y. This layout helps to prevent the folding bed 100 from tipping over or shaking when subjected to force, thus improving the safety of use.

[0086] Please refer to Figures 1 to 6 In this embodiment, the first wheel 114, the second wheel 162, and the third wheel 172 are all omnidirectional wheels.

[0087] The omnidirectional wheels feature three degrees of freedom in a plane (forward and backward movement, left and right movement, and rotation in place), making the folding bed 100 more flexible and convenient to move. Users can move the folding bed 100 in any direction through the combined movement of the omnidirectional wheels without changing its orientation. This design greatly simplifies the storage process and improves ease of use.

[0088] Please refer to Figures 1 to 6 In this embodiment, both the adjacent first sub-bed 121 and the second sub-bed 131 are provided with a clearance portion 180 at the ends closest to each other, so as to avoid each other when the adjacent first sub-bed 121 and the second sub-bed 131 are stacked.

[0089] Along the first direction X, the two first sub-bed bodies 121 are provided with a clearance part 180 at their respective ends, and the two second sub-bed bodies 131 are also provided with a clearance part 180 at their respective ends. The adjacent first sub-bed bodies 121 and second sub-bed bodies 131 are also provided with clearance parts 180. When the folding bed 100 is folded, interference between the first sub-bed bodies 121 or the second sub-bed bodies 131 can be avoided, thereby further improving the utilization efficiency of the folding bed 100.

[0090] The avoidance section 180 allows adjacent first sub-beds 121 and second sub-beds 131 to smoothly avoid each other when stacked, preventing folding difficulties caused by structural interference. This not only improves the folding efficiency of the folding bed 100 but also makes operation easier and more convenient for the user. The presence of the avoidance section 180 allows the folding bed 100 to form a more compact structure, thus making more efficient use of storage space. This is especially important in spaces with limited capacity, such as homes and offices, saving valuable space resources. The avoidance section 180 reduces friction and collisions between adjacent sub-beds during folding and unfolding, thereby reducing wear and damage caused by structural interference. This design helps extend the service life of the folding bed 100 and reduces user maintenance costs and repair frequency.

[0091] Please refer to Figures 1 to 6 In this embodiment, each first sub-bed 121 includes a first frame 190 and a first mattress 200 disposed on the first frame 190, and each second sub-bed 131 includes a second frame 210 and a second mattress 220 disposed on the second frame 210; the first frame 190 includes a first annular frame 191 and a plurality of first crossbeams 192 connected to the first annular frame 191, the plurality of first crossbeams 192 being spaced apart along a first direction X; the second frame 210 includes a second annular frame 211 and a plurality of second crossbeams 212 connected to the second annular frame 211, the plurality of second crossbeams 212 being spaced apart along a first direction X.

[0092] The first frame 190 and the second frame 210 can be constructed from carbon steel. Carbon steel has high strength and rigidity, and can withstand greater forces and pressures, making it significantly advantageous in applications requiring heavy loads and strength. This greatly expands the applicability of the folding bed 100, allowing even heavier individuals to use it. Alternatively, the first frame 190 and the second frame 210 can be constructed from titanium alloy. Due to the low density and high strength of titanium alloy, its specific strength is far greater than that of other metal structural materials. This allows for a lighter design of the first frame 190 and the second frame 210, facilitating folding and transport. Furthermore, because titanium alloy has a higher specific strength than other metals, the volume of the first frame 190 and the second frame 210 can be smaller while maintaining the same load-bearing capacity of the folding bed 100, further reducing the space occupied by the folding bed 100 when folded.

[0093] Both the first frame 190 and the second frame 210 adopt a combination design of ring frame and crossbeam. This design not only enhances the overall structural stability of the bed, but also enables the bed to evenly distribute the load and improve its load-bearing capacity. The ring frame, as the main support structure, can withstand greater external impact, while the crossbeam plays a role in strengthening and stabilizing, making the bed more robust and durable.

[0094] The first mattress 200 and the second mattress 220 are respectively mounted on the first frame 190 and the second frame 210. Thanks to the stability of the frames, the mattresses are fully supported and are not easily deformed or collapsed. This design also ensures a close fit between the mattress and the bed frame, reducing friction and noise between the mattress and the bed frame, and improving comfort.

[0095] Please refer to Figures 1 to 6In this embodiment, the first fixing frame 110 further includes a first connecting beam 115, which connects the first fixing block 111 and the second fixing block 112. The second fixing frame 140 further includes a second connecting beam 143, which connects the third fixing block 141 and the fourth fixing block 142. The folding bed 100 further includes a first connecting rod 230 and a first hydraulic rod 240. The two ends of the first connecting rod 230 in the length direction are respectively hinged to the first connecting beam 115 and the second connecting beam 143. The first hydraulic rod 240 includes a first cylinder 241 and a first piston rod 242. The first cylinder 241 is hinged to the first connecting rod 230, and one end of the first piston rod 242 in the length direction is slidably disposed on the first cylinder 230. Inside the first piston rod 242, the other end of the first piston rod 242 in the length direction is hinged to the first crossbeam 192; the third fixing frame 150 also includes a third connecting crossbeam 151, which connects the fifth fixing block 151 and the sixth fixing block 152; the folding bed 100 also includes a second connecting rod 250 and a second hydraulic rod 253, the two ends of the second connecting rod 250 in the length direction are respectively hinged to the first connecting crossbeam 115 and the third connecting crossbeam 151; the two hydraulic rods include a second cylinder 251 and a second piston rod 252, the second cylinder 251 is hinged to the second connecting rod 250, one end of the second piston rod 252 in the length direction is slidably disposed inside the second cylinder 251, and the other end of the second piston rod 252 in the length direction is hinged to the second crossbeam 212.

[0096] The first connecting beam 115 connects the first fixing block 111 and the second fixing block 112, and the second connecting beam 143 connects the third fixing block 141 and the fourth fixing block 142, forming a stable quadrilateral or similar structure, which enhances the overall stability of the folding bed 100. The addition of the third connecting beam 151 further enhances the stability of the structure, making the folding bed 100 more stable when bearing weight. The design of the first hydraulic rod 240 and the second hydraulic rod 253 not only provides folding and unfolding functions, but also enhances the support force of the bed frame when bearing weight. Moreover, the design of the first connecting rod 230 and the second connecting rod 250 allows the folding bed 100 to be easily folded and unfolded, facilitating user use in different scenarios.

[0097] Please refer to Figures 1 to 6In this embodiment, the folding bed 100 further includes a first limiting rod 260, one end of which is hinged to a first crossbeam 192. The first limiting rod 260 has a first elongated hole 261, the length direction of which is parallel to the length direction of the first limiting rod 260. The end of the first connecting rod 230 that is hinged to the first connecting crossbeam 115 is slidably engaged with the first elongated hole 261. The folding bed 100 also includes a second limiting rod 270, one end of which is hinged to a second crossbeam 212. The second limiting rod 270 has a second elongated hole 271, the length direction of which is parallel to the length direction of the second limiting rod 270. The end of the second connecting rod 250 that is hinged to the first connecting crossbeam 115 is slidably engaged with the second elongated hole 271.

[0098] The first limiting rod 260 slides with the first connecting rod 230 through the first elongated hole 261, and the second limiting rod 270 slides with the second connecting rod 250 through the second elongated hole 271, limiting the range of movement of the first connecting rod 230 or the second connecting rod 250 at the hinge point. This ensures that the first connecting rod 230 and the second connecting rod 250 remain on the predetermined trajectory during the unfolding or folding of the folding bed 100, thereby enhancing the structural stability of the entire folding bed 100. The design of the first elongated hole 261 and the second elongated hole 271 not only allows the first connecting rod 230 and the second connecting rod 250 to slide within a certain range, but also prevents the first connecting rod 230 and the second connecting rod 250 from falling off. Even if a large external impact is encountered during use, the first connecting rod 230 and the second connecting rod 250 can be effectively confined within the elongated holes, reducing the probability of danger caused by the first connecting rod 230 and the second connecting rod 250 falling off.

[0099] Please refer to Figures 1 to 6 In this embodiment, the folding bed 100 further includes a first support rod 280, the two ends of which are hinged to the fourth fixed frame 160 and the second connecting beam 143 respectively in the length direction; the folding bed 100 also includes a second support rod 290, the two ends of which are hinged to the fifth fixed frame 170 and the third connecting beam 151 respectively in the length direction.

[0100] The two ends of the first support rod 280 along its length are hinged to the fourth fixed frame 160 and the second connecting beam 143, respectively, while the two ends of the second support rod 290 along its length are hinged to the fifth fixed frame 170 and the third connecting beam 151, respectively. This hinged connection allows the folding bed 100 to form a stable support structure when unfolded. The hinged connection between the support rods and the fixed frames and connecting beams allows the folding bed 100 a certain degree of movement during folding and unfolding, while providing sufficient support force in the use state to ensure the stability and safety of the folding bed 100.

[0101] Please refer to Figure 7 In some embodiments, the folding bed 100 may further include a first telescopic rod 300 and a first sunshade 310. The first telescopic rod 300 is disposed on the first bed board or the second bed body 130. The first sunshade 310 is connected to the first telescopic rod 300. The first telescopic rod 300 includes a first sleeve 301 and a first rod 302. The first sunshade 310 is connected to the first sleeve 301 along the vertical direction Z. The first rod 302 is movably disposed inside the first sleeve 301. The first sunshade 310 is connected to the first rod 302, thereby the first sunshade 310 is movable in the vertical direction Z. When the user needs to rest, the first sunshade 310 can be driven to move to a suitable position in the vertical direction Z, thereby improving the user's sleep quality.

[0102] In some embodiments, the folding bed 100 further includes a first lifting ring 320, which is multiple and disposed on the first bed board and the second bed body 130, and the first lifting ring 320 facilitates lifting the folding bed 100.
