Turnover type functional bed and turnover method

Abstract

The invention relates to the technical field of bed structures, in particular to a turnover type functional bed and a turnover method. When the bed frame assembly needs to be lifted and folded, the mattress frame assembly is pulled to drive the mattress placed on the mattress frame assembly to move in the direction away from the backrest assembly, so that enough space is formed between the mattress frame assembly and the backrest assembly to accommodate the mattress, and the mattress is prevented from being damaged by pressing. The mattress frame assembly can move relative to the bed frame assembly to change the distance between the mattress frame assembly and the backrest assembly, so that the functional bed always has enough space for accommodating mattresses with different thicknesses, and the mattresses are prevented from being extruded and damaged. Due to the fact that the mattress frame assembly is pulled before the bed frame assembly is turned over, a user on the bed can be effectively prompted to leave the functional bed, and damage to the user in the turning and folding process is avoided. Therefore, the same functional bed is adaptive to mattresses with different thicknesses, and the mattresses are prevented from being extruded and damaged in the overturning process of the mattress frame assembly under the condition that the mattresses are close to the bed backrest.

Description

Technical Field

[0001] The present application relates to the technical field of bed structures, and in particular to a flip-type functional bed and a flipping method. Background Art

[0002] The functional bed can be completely hidden in the cabinet or wall through the vertical storage design, which significantly frees up the floor space. It is especially suitable for small-sized families and multi-functional room layouts. After the functional bed is folded, the room can be quickly switched to a study, living room or office area, meeting the flexible space needs of modern people.

[0003] In the process of folding and hiding the functional bed, the mattress frame is usually lifted on one side of the functional bed, so that the mattress frame is rotated along the other side thereof, and then the mattress frame is vertically folded, thereby achieving the effect of hiding the functional bed.

[0004] During the flipping and folding process of a functional bed, a certain distance is often left between the mattress frame and the backrest to prevent the mattress from being squeezed by the mattress frame and the backrest. On the one hand, this allows the mattress frame to be flipped and folded smoothly, and on the other hand, it avoids squeezing and damaging the mattress.

[0005] In the prior art, the distance between the mattress frame and the backrest is often fixed, resulting in each functional bed being able to accommodate only one thickness model of mattress. In terms of production design, it is often necessary to design functional beds of different styles and models for mattresses of different thicknesses, which will not only lead to waste in design and production, but also increase production costs and restrict business development. In terms of user use, after selecting a functional bed, users are often unable to replace mattresses of different thicknesses, thereby reducing the user experience and quality of life. In order to prevent the mattress from being squeezed and damaged during the flipping and folding process of the mattress frame, a certain gap often needs to be left between the mattress and the backrest, which will also cause the user's bedding items to often fall from the gap to the bottom of the bed or the gap between beds, resulting in loss of user items and obstruction of the functional bed.

[0006] It can be seen that how to make the same functional bed adapt to mattresses of different thicknesses and prevent the mattress from being squeezed and damaged during the flipping process of the mattress frame when the mattress is close to the bed backrest is a technical problem that needs to be solved urgently. Summary of the invention

In addition, the present invention provides examples of various specific processes and materials, but those of ordinary skill in the art can appreciate the application of other processes and / or the use of other materials.

[0078] See also Figures 1 to 4 In some embodiments of the present application, the present application provides a flip-type functional bed 01, comprising: a bed body 10, a bed frame assembly 20 and a mattress frame assembly 22. The bed body 10 is provided with a backrest assembly 11. The bed frame assembly 20 is rotatably mounted on the bed body 10. The mattress frame assembly 22 is slidably mounted on the bed frame assembly 20. In the process of the bed frame assembly 20 rotating relative to the bed body 10, the mattress frame assembly 22 rotates synchronously with the bed frame assembly 20. In the process of the mattress frame assembly 22 sliding relative to the bed frame assembly 20, if a mattress 70 is placed on the mattress frame assembly 22, the mattress frame assembly 22 drives the mattress 70 to move in a direction close to or away from the backrest assembly 11.

[0079] When the bed frame assembly 20 needs to be lifted and folded, the mattress frame assembly 22 is pulled to drive the mattress 70 placed on the mattress frame assembly 22 to move away from the backrest assembly 11, so that there is enough space between the mattress frame assembly 22 and the backrest assembly 11 to accommodate the mattress 70, thereby preventing the mattress 70 from being crushed and damaged. Since the mattress frame assembly 22 can move relative to the bed frame assembly 20 to change the distance between it and the backrest assembly 11, the functional bed 01 can be smoothly turned over and folded when mattresses 70 of different thicknesses are placed on the mattress frame assembly 22, and there is always enough space to accommodate mattresses 70 of different thicknesses to avoid squeezing and damaging the mattress 70. Since the mattress frame assembly 22 is pulled before the bed frame assembly 20 is turned over, the user on the bed can be effectively prompted to leave the functional bed 01 to avoid causing harm to the user during the turning and folding process. In this way, the same functional bed 01 can be adapted to mattresses 70 of different thicknesses and when the mattress 70 is close to the bed backrest, the mattress 70 can be prevented from being squeezed and damaged during the turning of the mattress frame assembly 22.

[0080] See also Figure 13 to Figure 14When the functional bed 01 is in normal use, the mattress 70 will be close to the backrest assembly 11, or even partially embedded in the backrest assembly 11, to ensure the compactness of the structure of the functional bed 01, to avoid the gap between the mattress 70 and the backrest assembly 11, which may cause the items on the bed to fall from the gap to the bottom of the bed, or get stuck in the structure of the functional bed 01 and cause damage to the functional bed 01. In the case where the mattress 70 is difficult to move, the mattress 70 is easily squeezed and damaged by the mattress frame assembly 22 and the backrest assembly 11. Even if the distance between the mattress frame assembly 22 and the backrest assembly 11 is calculated and designed to reduce the risk of the mattress 70 being squeezed and damaged, the functional bed 01 can only adapt to mattresses 70 of one thickness, and cannot be compatible with mattresses 70 of different thicknesses, resulting in the user being unable to replace mattresses 70 of different thicknesses. The flip-type functional bed 01 proposed in this application can be moved relative to the bed frame assembly 20 by pulling the mattress frame assembly 22, thereby making the distance between the mattress frame assembly 22 and the backrest assembly 11 variable. When the functional bed 01 needs to be used normally, the mattress frame assembly 22 is pushed when the bed frame assembly 20 is in use, so that any thickness of the mattress 70 can be close to the backrest assembly 11; when the functional bed 01 needs to be turned over and folded, the mattress frame assembly 22 can be pulled so that the mattress frame assembly 22 drives the mattress 70 away from the backrest assembly 11, so that there is always enough space between the mattress frame assembly 22 and the backrest assembly 11 to accommodate mattresses 70 of different thicknesses, so that the functional bed 01 can be compatible with mattresses 70 of any thickness, and there will never be a situation where there is not enough space between the mattress frame assembly 22 and the backrest assembly 11 and the mattress 70 is squeezed and damaged. Therefore, the same functional bed 01 can be compatible with mattresses 70 of different thicknesses and avoids the squeezing and damage of mattresses 70 of different thicknesses during the turning process of the mattress frame assembly 22 in any case.

[0081] See also Figures 5 to 9 In some embodiments of the present application, the flip-type functional bed 01 further includes a first positioning device 30, and the first positioning device 30 includes: a first handle assembly 31, a first positioning member 32, and a first connecting assembly 33. The first handle assembly 31 is rotatably mounted on the mattress frame assembly 22. The first positioning member 32 is slidably mounted on the mattress frame assembly 22. The first connecting assembly 33 connects the first handle assembly 31 and the first positioning member 32. Among them, the bed frame assembly 20 is provided with a limiting hole 21, and the first positioning member 32 is adapted to the limiting hole 21. In the process of rotating the first handle assembly 31, the first handle assembly 31 pulls the first connecting assembly 33 to drive the first positioning member 32 to partially extend into or completely move out of the limiting hole 21.

[0082] When it is necessary to rest on the functional bed 01, the functional bed 01 is in a folded and unfolded state. In this case, the mattress frame assembly 22 is positioned by the first positioning device 30 to prevent the mattress frame assembly 22 from sliding relative to the bed frame assembly 20, thereby keeping the position of the mattress frame assembly 22 stable, so that the user can rest safely on the functional bed 01. When it is necessary to lift and fold the bed frame assembly 20, the first positioning device 30 releases the positioning of the mattress frame assembly 22, thereby allowing the mattress frame assembly 22 to move relative to the bed frame assembly 20, and then the mattress frame assembly 22 drives the mattress 70 placed with the mattress frame assembly 22 to move in a direction away from the bed body 10, so that there is enough space between the mattress frame assembly 22 and the bed body 10 to accommodate the mattress 70, thereby preventing the mattress 70 from being crushed and damaged. Since the mattress frame assembly 22 can move relative to the bed frame assembly 20 to change the distance between the functional bed 01 and the bed body 10, the functional bed 01 can be smoothly flipped and folded when mattresses 70 of different thicknesses are placed on the mattress frame assembly 22, and there is always enough space to accommodate mattresses 70 of different thicknesses to avoid squeezing and damaging the mattress 70. Since the mattress frame assembly 22 is pulled before flipping the bed frame assembly 20, the user on the bed can be effectively prompted to leave the functional bed 01 to avoid injury to the user during the flipping and folding process. In this way, the same functional bed 01 can be adapted to mattresses 70 of different thicknesses and the safety of the functional bed 01 is guaranteed.

[0083] When the functional bed 01 is in normal use, part of the first positioning member 32 is inserted into the limiting hole 21, so that the first positioning member 32 is limited by the inner wall of the limiting hole 21, and the other part of the first positioning member 32 is located at the mattress frame assembly 22, and then the mattress frame assembly 22 is connected to the bed frame assembly 20 through the first positioning member 32, so as to prevent the mattress frame assembly 22 from sliding relative to the bed frame assembly 20, thereby keeping the position of the mattress frame assembly 22 stable, so that the user can rest safely on the functional bed 01.

[0084] When the bed frame assembly 20 needs to be lifted and folded, the first positioning device 30 is used to release the positioning of the mattress frame assembly 22, so that the mattress frame assembly 22 can move relative to the bed frame assembly 20, so that there is enough space between the mattress frame assembly 22 and the bed body 10 to accommodate the mattress 70, thereby preventing the mattress 70 from being crushed and damaging, and making the functional bed 01 compatible with mattresses 70 of different thicknesses.

[0085] In the process of releasing the mattress frame assembly 22 from being positioned at the bed frame assembly 20 through the first positioning device 30, the first handle assembly 31 is pulled, and then the first positioning member 32 is driven to move through the first connecting assembly 33, so that the first positioning member 32 is completely moved out of the limiting hole 21, thereby avoiding the inner wall of the limiting hole 21 from obstructing the first positioning member 32, so that the mattress frame assembly 22 can move smoothly relative to the bed frame assembly 20, and thus the mattress frame assembly 22 is released from being positioned at the bed frame assembly 20.

[0086] See also Figures 5 and 6 In some embodiments of the present application, the first connection assembly 33 includes: a first connection line 331 and a first elastic member 335. One end of the first connection line 331 is fixedly connected to the first handle assembly 31, and the other end of the first connection line 331 is fixedly connected to the first positioning member 32. The first elastic member 335 is disposed between the first positioning member 32 and the mattress frame assembly 22. In the process of the first handle assembly 31 rotating in the first direction, the first handle assembly 31 pulls the first connection line 331, so as to pull the first positioning member 32 through the first connection line 331 to overcome the elastic force of the first elastic member 335, so that the first positioning member 32 is completely moved out of the limiting hole 21. The first handle assembly 31 is released, and under the action of the elastic force of the first elastic member 335, the first positioning member 32 is partially inserted into the limiting hole 21.

[0087] When the functional bed 01 is put down for use, the bed frame assembly 20 is rotated downward, so that the bed frame assembly 20 drives the mattress frame assembly 22 and the mattress 70 to flip to a horizontal state, and the mattress frame assembly 22 is pushed so that the mattress 70 is close to the backrest assembly 11. When the first positioning member 32 reaches the position of the limiting hole 21, the first positioning member 32 partially extends into the limiting hole 21 under the elastic force of the first elastic member 335, so that the mattress frame assembly 22 is positioned through the mutual cooperation between the first positioning member 32 and the inner wall of the limiting hole 21, so as to prevent the mattress frame assembly 22 from sliding relative to the bed frame assembly 20, thereby keeping the position of the mattress frame assembly 22 stable, so that the user can rest safely on the functional bed 01.

[0088] When the bed frame assembly 20 needs to be lifted and folded, the first handle assembly 31 is pulled, and then the first handle assembly 31 pulls the first connecting line 331, so that the first positioning member 32 is pulled by the first connecting line 331 to overcome the elastic force of the first elastic member 335, so that the first positioning member 32 is completely moved out of the limiting hole 21, thereby avoiding the inner wall of the limiting hole 21 from obstructing the first positioning member 32, so that the mattress frame assembly 22 can move smoothly relative to the bed frame assembly 20. In this way, the mattress frame assembly 22 is released from the bed frame assembly 20, so that the mattress frame assembly 22 can move relative to the bed frame assembly 20.

[0089] Pull the mattress frame assembly 22 in a direction away from the backrest assembly 11 so that the mattress frame assembly 22 drives the mattress 70 away from the backrest assembly 11, thereby making enough space between the backrest assembly 11 and the mattress frame assembly 22 to accommodate the mattress 70, and thus the mattress 70 will not be squeezed and damaged during the process of turning over the bed frame assembly 20. Since the mattress frame assembly 22 can move relative to the bed frame assembly 20, the distance between the mattress frame assembly 22 and the backrest is adjustable, thereby making the functional bed 01 compatible with mattresses 70 of different thicknesses, so that users can have more choices, and manufacturers do not need to design multiple functional beds 01 to adapt to mattresses 70 of different thicknesses, thereby reducing production costs and improving corporate competitiveness.

[0090] In some embodiments of the present application, the first connection assembly 33 further includes: a first wire sleeve 332. The first wire sleeve 332 is tubular, and at least a portion of the first wire sleeve 332 is fixedly connected to the mattress frame assembly 22. The first connection line 331 is sleeved in the first wire sleeve 332, and the first connection line 331 can move relative to the first wire sleeve 332.

[0091] When the first handle assembly 31 pulls the first connection line 331, the first connection line 331 will be pulled as a whole, so that the first handle assembly 31 can smoothly pull the first positioning member 32. The first connection line 331 is sleeved in the first wire sleeve 332, so that the first connection line 331 moves in the first wire sleeve 332, so that the first connection line 331 is separated from other structures of the functional bed 01 by the first wire sleeve 332, so as to prevent other structures of the functional bed 01 from causing obstruction and wear to the first connection line 331, so that the first wire sleeve 332 protects the first connection line 331, so that the process of the first handle assembly 31 pulling the first positioning member 32 through the first connection line 331 is smoother, and the reliability of the first positioning member 32 positioning and releasing the mattress frame assembly 22 is ensured.

[0092] By making the first wire sleeve 332 at least partially fixedly connected to the mattress frame assembly 22, the first wire sleeve 332 is prevented from moving with the first connecting wire 331, so that the first connecting wire 331 is guided by the inner wall of the first wire sleeve 332, so that the movement of the first connecting wire 331 is smoother.

[0093] In some embodiments of the present application, the first connecting wire 331 and the first wire sleeve 332 are both configured as flexible linear structures.

[0094] By configuring the first connecting line 331 and the first wire sleeve 332 as flexible linear structures, the first connecting line 331 and the first wire sleeve 332 can adapt to different spatial arrangements, thereby making the installation positions of the first handle assembly 31 and the first positioning member 32 more flexible and making the spatial structure layout of the functional bed 01 more reasonable.

[0095] In some embodiments of the present application, the first connection assembly 33 further includes: a first fixing member 333 and a first guide member 334. The first fixing member 333 is fixedly mounted on the mattress frame assembly 22, and the first fixing member 333 is used to fix the portion of the first wire sleeve 332 close to the first handle assembly 31. The first guide member 334 is fixedly mounted on the mattress frame assembly 22, and the first guide member 334 is used to guide the first positioning member 32, and the portion of the first wire sleeve 332 close to the first positioning member 32 is fixedly connected to the first guide member 334.

[0096] The first fixing member 333 is fixedly installed on the mattress frame assembly 22, and the first wire sleeve 332 is fixed by the first fixing member 333 near the first handle assembly 31, so as to prevent the first wire sleeve 332 from being pulled by the first handle assembly 31 when the first handle assembly 31 pulls the first connecting wire 331, thereby ensuring the stability of the positions of the first connecting wire 331 and the first wire sleeve 332, and enabling the first connecting wire 331 to reliably move relative to the first wire sleeve 332, so that the process of the first handle assembly 31 pulling the first positioning member 32 through the first connecting wire 331 is smoother, thereby ensuring the reliability of the first positioning member 32 in positioning and releasing the mattress frame assembly 22.

[0097] When the first positioning member 32 is pulled by the first handle assembly 31 through the first connecting line 331, the first positioning member 32 is guided by the first guide member 334 so that the moving direction of the first positioning member 32 remains fixed, thereby ensuring the reliability of the first positioning member 32 in positioning and releasing the mattress frame assembly 22.

[0098] In some embodiments of the present application, the first positioning member 32 is a rod-shaped structure, and the first guide member 334 is provided with a guide hole, and the inner wall shape of the guide hole is adapted to the outer contour shape of the first positioning member 32 .

[0099] See also Figures 4 to 5In some embodiments of the present application, the mattress frame assembly 22 includes: a frame transverse bracket 221, a middle vertical bracket 222, a side vertical bracket 223 and a connecting bracket 224. The frame transverse bracket 221 is located on a side of the mattress frame assembly 22 away from the backrest assembly 11. The middle vertical bracket 222 is connected to the middle position of the frame transverse bracket 221. The side vertical bracket 223 is connected to the side end of the frame transverse bracket 221. The connecting bracket 224 is used to connect the middle vertical bracket 222 to the side transverse bracket. Among them, the frame transverse bracket 221, the middle vertical bracket 222, the side vertical bracket 223 and the connecting bracket 224 are all configured as tubular structures, and the internal spaces of the frame transverse bracket 221, the middle vertical bracket 222, the side vertical bracket 223 and the connecting bracket 224 are connected to form a tubular channel. The first connecting line 331 is arranged in the tubular channel. The limiting hole 21 is disposed at a position in the side frame of the bed frame assembly 20 corresponding to the first positioning member 32 .

[0100] By connecting the middle vertical bracket 222 with the middle position of the frame horizontal bracket 221, when the first connecting line 331 enters the middle vertical bracket 222 from the frame horizontal bracket 221, the first connecting line 331 exits the frame horizontal bracket 221 from the middle position of the frame horizontal bracket 221. Since the connecting bracket 224 connects the middle vertical bracket 222 and the side horizontal bracket, the first connecting line 331 in the middle vertical bracket enters the connecting bracket 224 after being bent and reaches the side vertical bracket 223. Through the above arrangement, the first connecting line 331 is arranged in a horizontal "U" shape, so that the first connecting line 331 can pull the first positioning member 32 laterally, so that the first positioning member 32 can move in a direction away from the limiting hole 21 located on the side of the bed frame assembly 20, and then the first positioning member 32 can be smoothly pulled out of the limiting hole 21 by the first handle assembly 31 through the first connecting line 331, and then the mattress frame assembly 22 can be smoothly released from the positioning, so that the mattress frame assembly 22 can move relative to the bed frame assembly 20.

[0101] In some embodiments of the present application, the first handle assembly 31 is rotatably mounted at the middle position of the frame horizontal bracket 221 , and the first guide member 334 is fixedly mounted on the side vertical bracket 223 .

[0102] When the first handle assembly 31 is pulled, the mattress frame assembly 22 is subjected to a pulling force in a direction away from the backrest assembly 11 . Pulling the first handle assembly 31 will produce two stages of effects: in the first stage, due to the positioning of the mattress frame assembly 22 by the first positioning member 32, the mattress frame assembly 22 cannot be pulled during the process of pulling the first handle assembly 31, thereby causing the first handle assembly 31 to rotate relative to the frame transverse bracket 221. At this time, the first handle assembly 31 can pull the first positioning member 32 through the first connecting line 331, thereby releasing the positioning of the mattress frame assembly 22; in the second stage, since the mattress frame assembly 22 is released from the positioning, the first handle assembly 31 is continued to be pulled, thereby allowing the first handle assembly 31 to be close to the frame transverse bracket 221, thereby pulling the mattress frame assembly 22 relative to the bed frame assembly 20 in a direction away from the backrest assembly 11, thereby making the distance between the mattress frame assembly 22 and the backrest adjustable, thereby making the functional bed 01 compatible with mattresses 70 of different thicknesses, allowing users to have more choices, and eliminating the need for manufacturers to design multiple functional beds 01 to adapt to mattresses 70 of different thicknesses, thereby reducing production costs and improving corporate competitiveness.

[0103] By rotating and installing the first handle assembly 31 in the middle position of the frame transverse bracket 221, on the one hand, the first handle assembly 31 is close to the outer side of the mattress frame assembly 22, so that the user can easily pull the first handle assembly 31; on the other hand, the force applied to the mattress frame assembly 22 during the pulling process is more uniform, reducing the risk of the mattress frame assembly 22 being stuck due to lateral pulling force, so that the mattress frame assembly 22 can be pulled out more smoothly and reliably.

[0104] See also Figure 4 and Fig. 9 In some embodiments of the present application, the first handle assembly 31 includes: a handle bar 311 and a rotating connection member 312. The rotating connection member 312 is installed at both ends of the handle bar 311, and the rotating connection member 312 is rotatably connected to the frame horizontal bracket 221, and one end of the first connecting line 331 is clamped on the rotating connection member 312. Pulling the handle bar 311 can make the rotating connection member 312 rotate relative to the frame horizontal bracket 221.

[0105] In the process of pulling out the mattress frame assembly 22, the user can stand at the end of the bed and feel towards the bottom of the bed to confirm the position of the first handle assembly 31. After confirming the position of the first handle assembly 31, the user holds the handle rod 311 and pulls the handle rod 311, so that the handle rod 311 drives the rotating connector 312 to rotate, and then pulls the first connecting line 331 through the rotating connector 312, and pulls the first positioning member 32 through the first connecting line 331, so that the first positioning member 32 is completely pulled out of the limiting hole 21, so that the positioning of the mattress frame assembly 22 is released, so that the mattress frame assembly 22 can be pulled out from the bed frame assembly 20. In the process of pulling the handle rod 311, the handle rod 311 approaches the frame transverse bracket 221 until it abuts against the frame transverse bracket 221. Since the mattress frame assembly 22 can be released from its position by pulling the handle rod 311, when the handle rod 311 abuts against the frame transverse bracket 221, if the handle rod 311 continues to be pulled, the mattress frame assembly 22 can be smoothly pulled out in the direction away from the backrest assembly 11, so that there is enough space between the mattress frame assembly 22 and the backrest assembly 11 to accommodate the mattress 70, thereby preventing the mattress 70 from being crushed and damaged, and making the distance between the mattress frame assembly 22 and the backrest adjustable, so that the functional bed 01 can be compatible with mattresses 70 of different thicknesses, so that users can have more choices and manufacturers do not need to design multiple functional beds 01 to adapt to mattresses 70 of different thicknesses, thereby reducing production costs and improving corporate competitiveness.

[0106] See also Figures 9 and 10 In some embodiments of the present application, the rotating connector 312 is respectively located on both sides of the middle vertical bracket 222. A direction-changing assembly 40 is installed inside the frame horizontal bracket 221, and the direction-changing assembly 40 includes: a first pulley 41, a second pulley 42 and a third pulley 43. The pulley groove of the first pulley 41 is close to the position where the first connecting line 331 is connected to the rotating connector 312. The second pulley 42 is arranged in parallel with the first pulley 41, and the position of the pulley groove of the first pulley 41 corresponds to the position of the pulley groove of the first pulley 41. The third pulley 43 is located between the first pulley 41 and the second pulley 42. Among them, the rotation center axis of the first pulley 41 and the second pulley 42 is parallel to the rotation center axis of the rotating connector 312. The rotation center axis of the third pulley 43 is perpendicular to the rotation center axis of the rotating connector 312.

[0107] The end of the first connecting line 331 is connected to the rotating connecting member 312 by a clamping method, so that the first connecting line 331 can be pulled during the rotation of the rotating connecting member 312. After the first connecting line 331 is led out from the rotating connecting member 312, it enters the guiding range of the first pulley 41, and then the arrangement direction of the first connecting line 331 is changed through the first pulley 41, so that the first connecting line 331 can reach the second pulley 42, and then the arrangement direction of the first connecting line 331 is changed again through the second pulley 42, so that the first connecting line 331 can reach the third pulley 43, and then the arrangement direction of the first connecting line 331 is changed again through the third pulley 43. Since the rotation center axes of the first pulley 41 and the second pulley 42 are parallel to the rotation center axis of the rotating connection member 312, when the first pulley 41 changes the arrangement direction of the first connecting line 331, the first connecting line 331 is arranged vertically downward and then reaches the second pulley 42, so that the first connecting line 331 is changed in direction again by the second pulley 42 and reaches the third pulley 43, thereby avoiding the first connecting line 331 from directly reaching the third pulley 43 from the first pulley 41 and increasing the risk of the first connecting line 331 falling off the first pulley 41; since the rotation center axis of the third pulley 43 is perpendicular to the rotation center axis of the rotating connection member 312, when the first connecting line 331 is changed in direction by the third pulley 43, it can be arranged in the horizontal direction and along the horizontal bracket of the frame. The internal space of 221 extends toward the middle position of the frame horizontal bracket 221 until it reaches the connection between the middle vertical bracket 222 and the frame horizontal bracket 221, and then enters the middle vertical bracket 222, and then the middle vertical bracket 222 enters the connecting bracket 224 until it is connected to the first positioning member 32 installed on the side vertical bracket 223. In this way, the first connecting line 331 can pull the first positioning member 32 laterally so that the first positioning member 32 can move away from the limiting hole 21 located on the side of the bed frame assembly 20, and then the first positioning member 32 can be smoothly pulled out of the limiting hole 21 by the first handle assembly 31 through the first connecting line 331, and then the mattress frame assembly 22 can be smoothly released from the positioning, so that the mattress frame assembly 22 can move relative to the bed frame assembly 20.

[0108] Through the spatial arrangement of the first pulley 41, the second pulley 42 and the third pulley 43, the arrangement direction of the first connecting line 331 can be effectively changed, and the first connecting line 331 can be avoided from being stuck, so that the first handle assembly 31 can smoothly pull the first positioning member 32 through the first connecting line 331, ensuring the reliability of the process in which the first positioning member 32 unlocks the mattress frame assembly 22.

[0109] See also Figures 1 to 9In some embodiments of the present application, the present application further provides a functional bed 01, comprising: a bed body 10, a bed frame assembly 20, a mattress frame assembly 22, a first positioning device 30, and a second positioning device 50. The bed frame assembly 20 is rotatably mounted on the bed body 10. The mattress frame assembly 22 is slidably mounted on the bed frame assembly 20. The first positioning device 30 is used to position the mattress frame assembly 22 relative to the bed frame assembly 20. The second positioning device 50 is used to position the bed frame assembly 20 relative to the bed body 10. In the process of the bed frame assembly 20 rotating relative to the bed body 10, the mattress frame assembly 22 rotates synchronously with the bed frame assembly 20. When the bed frame assembly 20 reaches the use position, the second positioning device 50 positions the bed frame assembly 20 to prevent the bed frame assembly 20 from rotating relative to the bed body 10. When the mattress frame assembly 22 reaches the use position, the first positioning device 30 positions the mattress frame assembly 22 to prevent the mattress frame assembly 22 from sliding relative to the bed frame assembly 20.

[0110] When it is necessary to rest on the functional bed 01, the functional bed 01 is in the unfolded state. In this case, the mattress frame assembly 22 is positioned by the first positioning device 30 to prevent the mattress frame assembly 22 from sliding relative to the bed frame assembly 20, thereby keeping the position of the mattress frame assembly 22 stable, so that the user can rest safely on the functional bed 01; at the same time, the second positioning device 50 positions the bed frame assembly 20 to prevent the bed frame assembly 20 from rotating relative to the bed body 10, thereby preventing the bed frame assembly 20 from being accidentally lifted and folded, and ensuring the safety of the user during rest. When it is necessary to lift and fold the bed frame assembly 20, the first positioning device 30 releases the positioning of the mattress frame assembly 22, thereby allowing the mattress frame assembly 22 to move relative to the bed frame assembly 20, and then the mattress frame assembly 22 drives the mattress 70 placed with the mattress frame assembly 22 to move away from the bed body 10, so that there is enough space between the mattress frame assembly 22 and the bed body 10 to accommodate the mattress 70, thereby preventing the mattress 70 from being crushed and damaged. Since the mattress frame assembly 22 can move relative to the bed frame assembly 20 to change the distance between the functional bed 01 and the bed body 10, the functional bed 01 can be smoothly turned over and folded when mattresses 70 of different thicknesses are placed on the mattress frame assembly 22, and there is always enough space to accommodate mattresses 70 of different thicknesses to avoid squeezing and damaging the mattress 70. After the mattress frame assembly 22 and the mattress 70 are pulled out away from the bed body 10, the second positioning device 50 releases the positioning of the bed frame assembly 20, so that the bed frame assembly 20 and the mattress frame assembly 22 are turned over and lifted together, so that the functional bed 01 can be smoothly turned over and folded. Since the mattress frame assembly 22 is pulled before the bed frame assembly 20 is turned over, the user on the bed can be effectively prompted to leave the functional bed 01 to avoid injury to the user during the turning and folding process. In this way, the same functional bed 01 can be adapted to mattresses 70 of different thicknesses and the safety of the functional bed 01 is guaranteed.

[0111] In some embodiments of the present application, the first positioning device 30 includes: a first handle assembly 31, a first positioning member 32, and a first connecting assembly 33. The first handle assembly 31 is rotatably mounted on the mattress frame assembly 22. The first positioning member 32 is slidably mounted on the mattress frame assembly 22. The first connecting assembly 33 connects the first handle assembly 31 and the first positioning member 32. The bed frame assembly 20 is provided with a limiting hole 21, and the first positioning member 32 is adapted to the limiting hole 21. In the process of rotating the first handle assembly 31, the first handle assembly 31 pulls the first connecting assembly 33 to drive the first positioning member 32 to partially extend into or completely move out of the limiting hole 21.

[0112] When it is necessary to rest on the functional bed 01, the functional bed 01 is in a folded and unfolded state. In this case, the mattress frame assembly 22 is positioned by the first positioning device 30 to prevent the mattress frame assembly 22 from sliding relative to the bed frame assembly 20, thereby keeping the position of the mattress frame assembly 22 stable, so that the user can rest safely on the functional bed 01. When it is necessary to lift and fold the bed frame assembly 20, the first positioning device 30 releases the positioning of the mattress frame assembly 22, thereby allowing the mattress frame assembly 22 to move relative to the bed frame assembly 20, and then the mattress frame assembly 22 drives the mattress 70 placed with the mattress frame assembly 22 to move in a direction away from the bed body 10, so that there is enough space between the mattress frame assembly 22 and the bed body 10 to accommodate the mattress 70, thereby preventing the mattress 70 from being crushed and damaged. Since the mattress frame assembly 22 can move relative to the bed frame assembly 20 to change the distance between the functional bed 01 and the bed body 10, the functional bed 01 can be smoothly flipped and folded when mattresses 70 of different thicknesses are placed on the mattress frame assembly 22, and there is always enough space to accommodate mattresses 70 of different thicknesses to avoid squeezing and damaging the mattress 70. Since the mattress frame assembly 22 is pulled before flipping the bed frame assembly 20, the user on the bed can be effectively prompted to leave the functional bed 01 to avoid injury to the user during the flipping and folding process. In this way, the same functional bed 01 can be adapted to mattresses 70 of different thicknesses and the safety of the functional bed 01 is guaranteed.

[0113] When the functional bed 01 is in normal use, part of the first positioning member 32 is inserted into the limiting hole 21, so that the first positioning member 32 is limited by the inner wall of the limiting hole 21, and the other part of the first positioning member 32 is located at the mattress frame assembly 22, and then the mattress frame assembly 22 is connected to the bed frame assembly 20 through the first positioning member 32, so as to prevent the mattress frame assembly 22 from sliding relative to the bed frame assembly 20, thereby keeping the position of the mattress frame assembly 22 stable, so that the user can rest safely on the functional bed 01.

[0114] When the bed frame assembly 20 needs to be lifted and folded, the first positioning device 30 is used to release the positioning of the mattress frame assembly 22, so that the mattress frame assembly 22 can move relative to the bed frame assembly 20, so that there is enough space between the mattress frame assembly 22 and the bed body 10 to accommodate the mattress 70, thereby preventing the mattress 70 from being crushed and damaging, and making the functional bed 01 compatible with mattresses 70 of different thicknesses.

[0115] In the process of releasing the mattress frame assembly 22 from being positioned at the bed frame assembly 20 through the first positioning device 30, the first handle assembly 31 is pulled, and then the first positioning member 32 is driven to move through the first connecting assembly 33, so that the first positioning member 32 is completely moved out of the limiting hole 21, thereby avoiding the inner wall of the limiting hole 21 from obstructing the first positioning member 32, so that the mattress frame assembly 22 can move smoothly relative to the bed frame assembly 20, and thus the mattress frame assembly 22 is released from being positioned at the bed frame assembly 20.

[0116] In some embodiments of the present application, the second positioning device 50 includes: a second handle assembly 51, a second positioning member 52, a second connecting assembly 53 and a limiting assembly 54. The second handle assembly 51 is rotatably mounted on the bed frame assembly 20. The second positioning member 52 is slidably mounted on the bed frame assembly 20. The second connecting assembly 53 connects the second handle assembly 51 and the second positioning member 52. The limiting assembly 54 is fixedly mounted on the bed body 10. In the process of rotating the second handle assembly 51, the second handle assembly 51 pulls the second connecting assembly 53 to drive the second positioning member 52 to partially extend into the limiting range of the limiting assembly 54 or completely move out of the limiting range of the limiting assembly 54.

[0117] After the mattress frame assembly 22 is pulled out of the expected distance relative to the bed frame assembly 20, the second handle assembly 51 can be pulled to rotate the second handle assembly 51 relative to the bed frame assembly 20, and then the second connection assembly 53 is pulled by the second handle assembly 51 to drive the second positioning member 52 to move the second positioning member 52 completely out of the limiting range of the limiting assembly 54, thereby unlocking the bed frame assembly 20, so that the bed frame assembly 20 can rotate relative to the bed body 10, and then the bed frame assembly 20 together with the mattress frame assembly 22 and the mattress 70 are turned over and folded, so as to store the functional bed 01. Before pulling the second handle assembly 51, the second positioning member 52 partially extends into the limiting range of the limiting assembly 54, so that the bed frame assembly 20 is positioned by the second positioning member 52 to prevent the bed frame assembly 20 from rotating relative to the bed body 10, thereby preventing the bed frame assembly 20 from being accidentally lifted and folded, and ensuring the safety of the user during rest.

[0118] In some embodiments of the present application, the second connection assembly 53 includes: a second connection line 531, a second elastic member 532, a second wire sleeve 533, a second fixing member 534 and a second guide member 535. One end of the second connection line 531 is fixedly connected to the second handle assembly 51, and the other end of the second connection line 531 is fixedly connected to the second positioning member 52. The second elastic member 532 is arranged between the second positioning member 52 and the mattress frame assembly 22. The second wire sleeve 533 is tubular, and the second connection line 531 is sleeved in the second wire sleeve 533, and the second connection line 531 can move relative to the second wire sleeve 533. The second fixing member 534 is fixedly installed on the bed frame assembly 20, and the second fixing member 534 is used to fix the part of the second wire sleeve 533 close to the second handle assembly 51. The second guide member 535 is fixedly installed on the bed frame assembly 20, and the second guide member 535 is used to guide the second positioning member 52, and the part of the second wire sleeve 533 close to the second positioning member 52 is fixedly connected to the second guide member 535. When the second handle assembly 51 rotates in the second direction, the second handle assembly 51 pulls the second connection line 531, so as to pull the second positioning member 52 through the second connection line 531 to overcome the elastic force of the second elastic member 532, so that the second positioning member 52 is completely moved out of the limiting range of the limiting assembly 54. When the second handle assembly 51 is released, the second positioning member 52 partially extends into the limiting range of the limiting assembly 54 under the elastic force of the second elastic member 532.

[0119] Pull the second handle assembly 51, and then the second handle assembly 51 pulls the second connecting line 531, thereby pulling the second positioning member 52 through the second connecting line 531 to move the second positioning member 52 completely out of the limiting range of the limiting assembly 54, thereby unlocking the bed frame assembly 20, so that the bed frame assembly 20 can rotate relative to the bed body 10, and then the bed frame assembly 20 together with the mattress frame assembly 22 and the mattress 70 are flipped and folded, so that the functional bed 01 is stored.

[0120] When the second connection line 531 pulls the second positioning member 52, the second connection line 531 will be pulled as a whole, so that the second handle assembly 51 can smoothly pull the second positioning member 52. The second connection line 531 is sleeved in the second line sleeve 533, so that the second connection line 531 moves in the second line sleeve 533, so that the second connection line 531 is separated from other structures of the functional bed 01 by the second line sleeve 533, so as to prevent other structures of the functional bed 01 from causing obstruction and wear to the second connection line 531, so that the second line sleeve 533 protects the first connection line 331, so that the process of the second handle assembly 51 pulling the second positioning member 52 through the second connection line 531 is smoother, and the reliability of the second positioning member 52 positioning and releasing the bed frame assembly 20 is ensured.

[0121] By fixing the second wire sleeve 533 near the second handle assembly 51 with the second fixing member 534 and fixing the second fixing member 534 on the bed frame assembly 20, the second wire sleeve 533 is at least partially fixedly connected to the bed frame assembly 20, thereby preventing the second wire sleeve 533 from moving with the second connecting line 531, and thus guiding the second connecting line 531 through the inner wall of the second wire sleeve 533, so that the movement of the second connecting line 531 is smoother.

[0122] By fixing the second fixing member 534 to the bed frame assembly 20 and fixing the second wire loop 533 near the second handle assembly 51 through the second fixing member 534, the second wire loop 533 is prevented from being pulled by the second handle assembly 51 when the second handle assembly 51 pulls the second connecting wire 531, thereby ensuring the stability of the positions of the second connecting wire 531 and the second wire loop 533, and enabling the second connecting wire 531 to reliably move relative to the second wire loop 533, thereby making the process of the second handle assembly 51 pulling the second positioning member 52 through the second connecting wire 531 smoother, thereby ensuring the reliability of the second positioning member 52 in positioning and releasing the bed frame assembly 20.

[0123] When the second positioning member 52 is pulled by the second handle assembly 51 through the second connecting line 531, the second positioning member 52 is guided by the second guide member 535 so that the moving direction of the second positioning member 52 remains fixed, thereby ensuring the reliability of the second positioning member 52 in positioning and releasing the bed frame assembly 20.

[0124] When the functional bed 01 is put down for use, the bed frame assembly 20 is rotated downward, so that the bed frame assembly 20 drives the mattress frame assembly 22 and the mattress 70 to turn to a horizontal state. When the second positioning member 52 reaches the limit range of the limit assembly 54, the second positioning member 52 partially extends into the limit range of the limit assembly 54 under the elastic force of the second elastic member 532, so that the bed frame assembly 20 is positioned through the cooperation between the second positioning member 52 and the limit assembly 54, so as to prevent the bed frame assembly 20 from rotating relative to the bed body 10, thereby preventing the bed frame assembly 20 from being accidentally lifted and folded, and ensuring the safety of the user during rest.

[0125] In some embodiments of the present application, the second positioning member 52 is a rod-shaped structure, and the second guide member 535 is provided with a guide hole, and the inner wall shape of the guide hole is adapted to the outer contour shape of the second positioning member 52 .

[0126] In some embodiments of the present application, the second connecting wire 531 and the second wire sleeve 533 are both configured as flexible linear structures.

[0127] By configuring the second connecting line 531 and the second wire sleeve 533 as flexible linear structures, the second connecting line 531 and the second wire sleeve 533 can adapt to different spatial arrangements, thereby making the installation position of the second handle assembly 51 and the second positioning member 52 more flexible and making the spatial structure layout of the functional bed 01 more reasonable.

[0128] See also Fig.12 In some embodiments of the present application, the limiting assembly 54 includes: a limiting fixing member 541, a limiting sliding member 542 and a limiting adjusting member 543. The limiting fixing member 541 is fixedly mounted on the bed frame assembly 20. The limiting sliding member 542 is slidably mounted on the limiting fixing member 541, and the limiting sliding member 542 is provided with a limiting surface. The limiting adjusting member 543 is used to adjust the relative height between the limiting surface and the limiting fixing member 541. Among them, when the second positioning member 52 partially extends into the limiting range of the limiting assembly 54, the second positioning member 52 abuts against the limiting sliding member 542 at the limiting surface.

[0129] It is understandable that if the height of the limiting surface of the limiting sliding member 542 is too high, the second positioning member 52 will be blocked by the side of the limiting sliding member 542 during the movement toward the limiting assembly 54, and thus cannot abut against the limiting sliding member 542 at the limiting surface, and thus cannot achieve the positioning of the bed frame assembly 20. If the limiting surface of the limiting sliding member 542 is too low, there will be a certain distance between the second positioning member 52 and the limiting surface of the limiting sliding member 542 after the second positioning member 52 is extended into the limiting range of the limiting assembly 54, thereby causing a loose space between the bed frame assembly 20 and the bed body 10, affecting the positioning effect of the bed frame assembly 20.

[0130] The relative height between the limiting surface of the limiting sliding member 542 and the limiting fixing member 541 is adjusted by the limiting adjusting member 543, so that the second positioning member 52 can smoothly extend into the limiting range of the limiting assembly 54 and abut against the limiting sliding member 542 at the limiting surface, thereby ensuring the reliability of the second positioning member 52 in positioning the bed frame assembly 20.

[0131] In some embodiments of the present application, the limit adjustment member 543 is rotatably mounted on the limit fixing member 541. The connection mode of the limit adjustment member 543 and the limit sliding member 542 is configured as a threaded connection. In the process of rotating the limit adjustment member 543, under the action of the connecting thread, the limit adjustment member 543 causes the limit sliding member 542 to move relative to the limit fixing member 541.

[0132] When it is necessary to adjust the height of the limiting surface of the limiting sliding member 542, the limiting adjusting member 543 is rotated by a tool such as a wrench, and then under the action of the connecting thread, the limiting adjusting member 543 causes the limiting sliding member 542 to move relative to the limiting fixing member 541. In this way, the relative height of the limiting surface of the limiting sliding member 542 and the limiting fixing member 541 is adjusted, so that the second positioning member 52 can be smoothly extended into the limiting range of the limiting assembly 54, and abut against the limiting sliding member 542 at the limiting surface, thereby ensuring the reliability of the second positioning member 52 in positioning the bed frame assembly 20.

[0133] See also Figure 4 and Fig.11 In some embodiments of the present application, the functional bed 01 further includes a guide device 60 , and the guide device 60 is used to guide the mattress frame assembly 22 during the movement of the mattress frame assembly 22 relative to the bed frame assembly 20 .

[0134] During the movement of the mattress frame assembly 22 relative to the bed frame assembly 20, the mattress frame assembly 22 is guided by the guide device 60, thereby making the relative movement of the mattress frame assembly 22 and the bed frame assembly 20 smoother and more labor-saving, thereby allowing the user to move the mattress frame assembly 22 more easily and smoothly.

[0135] In some embodiments of the present application, the guide device 60 includes: a guide rail assembly 61 and a slider assembly 62. The guide rail assembly 61 is fixedly mounted on the bed frame assembly 20. The slider assembly 62 is fixedly mounted on the mattress frame assembly 22, and the slider assembly 62 is adapted to the guide rail assembly 61, and the slider assembly 62 is slidably connected to the guide rail assembly 61.

[0136] By the cooperation between the slide rail assembly and the slider assembly 62, the mattress frame assembly 22 is guided by the guide device 60, so that the relative movement of the mattress frame assembly 22 and the bed frame assembly 20 is smoother and more labor-saving, so that the user can move the mattress frame assembly 22 more easily and smoothly.

[0137] In some embodiments of the present application, the guide rail assembly 61 includes: a first guide rail member 611, a second guide rail member 612, and a limit stopper 613. The first guide rail member 611 is fixedly installed on the bed frame assembly 20. The second guide rail member 612 is fixedly installed on the same side of the bed frame assembly 20 as the first guide rail member 611. The limit stopper 613 is fixedly installed on the mattress frame assembly 22. When the mattress frame assembly 22 is pulled out to the first limit position, the limit stopper 613 abuts against the first guide rail member 611. When the mattress frame assembly 22 is pushed in to the second limit position, the limit stopper 613 abuts against the second guide rail member 612.

[0138] When the mattress frame assembly 22 is pulled out to the first extreme position, the relative distance between the mattress frame assembly 22 and the backrest assembly 11 reaches the maximum, and then the range in which the mattress frame assembly 22 is pulled out is limited by the cooperation between the first guide rail member 611 and the limit block 613, thereby preventing the mattress frame assembly 22 from detaching from the bed frame assembly 20, thereby ensuring the stability and reliability of the main structure of the functional bed 01.

[0139] When the mattress frame assembly 22 is pushed into the second limit position, the distance between the mattress frame assembly 22 and the backrest assembly 11 reaches the minimum. At this time, if a mattress 70 is placed on the mattress frame assembly 22, the mattress 70 is close to the backrest assembly 11. The cooperation between the second guide rail member 612 and the limit block 613 limits the range in which the mattress frame assembly 22 is pushed, thereby preventing the mattress frame assembly 22 from colliding with the backrest assembly 11, thereby preventing the functional bed 01 from being damaged, ensuring the reliability of the structure of the functional bed 01 and reducing the failure rate of the functional bed 01.

[0140] In some embodiments of the present application, the limiting hole 21 is opened in the slider assembly 62 .

[0141] By setting the limiting hole 21 on the slider assembly 62, the first positioning member 32 can cooperate with the limiting hole 21 to position the mattress frame assembly 22 after reaching the position of the slider assembly 62, thereby eliminating the need for an additional structure to limit the first positioning member 32, reducing the application of production materials and simplifying the structure of the functional bed 01, thereby reducing the production cost of the functional bed 01 and enhancing the company's competitiveness.

[0142] On the other hand, the present application also provides a flipping method for flipping the above flip-type functional bed 01, comprising the following steps:

[0143] Pull the first handle assembly 31 to move the first positioning member 32 completely out of the limiting hole 21;

[0144] Pulling the mattress frame assembly 22 so that the mattress frame assembly 22 moves away from the backrest assembly 11, and the bed frame assembly 20 reaches the desired position;

[0145] The bed frame assembly 20 is rotated so that the bed frame assembly 20 and the mattress frame assembly 22 are rotated relative to the bed body 10 , thereby realizing the flipping and folding of the flip-type functional bed 01 .

[0146] It is understandable that when the bed frame assembly 20 needs to be lifted and folded, the mattress frame assembly 22 is pulled to drive the mattress 70 placed on the mattress frame assembly 22 to move away from the backrest assembly 11, so that there is enough space between the mattress frame assembly 22 and the backrest assembly 11 to accommodate the mattress 70, thereby preventing the mattress 70 from being crushed and damaged. Since the mattress frame assembly 22 can move relative to the bed frame assembly 20 to change the distance between it and the backrest assembly 11, the functional bed 01 can be smoothly turned over and folded when mattresses 70 of different thicknesses are placed on the mattress frame assembly 22, and there is always enough space to accommodate mattresses 70 of different thicknesses to avoid squeezing and damaging the mattress 70. Since the action of pulling the mattress frame assembly 22 before turning over the bed frame assembly 20 can effectively prompt the user on the bed to leave the functional bed 01, avoiding injury to the user during the turning and folding process. In this way, the same functional bed 01 is adapted to mattresses 70 of different thicknesses and when the mattress 70 is close to the bed backrest, the mattress 70 is prevented from being squeezed and damaged during the turning of the mattress frame assembly 22.
