Functional bed

Abstract

The utility model relates to the technical field of bed structures, in particular to a functional bed. When the functional bed is in a put-down and unfolded state, the mattress frame assembly is positioned through the first positioning device, so that the mattress frame assembly is prevented from sliding relative to the bed frame assembly; meanwhile, the second positioning device is used for positioning the bed frame assembly to prevent the bed frame assembly from rotating relative to the bed main body, so that the bed frame assembly is prevented from being lifted and folded by mistake, and the safety of the user in the rest process is guaranteed. The mattress frame assembly can move relative to the bed frame assembly to change the distance between the mattress frame assembly and the bed main body, 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 safety of the functional bed is ensured.

Description

[0078] Please refer to Figures 1 to 4 In some embodiments of the present application, the utility model provides a turnover type functional bed 01, which comprises a bed main body 10, a bed frame assembly 20 and a mattress frame assembly 22. The bed main body 10 is provided with a backrest assembly 11. The bed frame assembly 20 is rotatably installed on the bed main body 10. The mattress frame assembly 22 is slidably installed on the bed frame assembly 20. Wherein, in the process of rotating the bed frame assembly 20 relative to the bed main body 10, the mattress frame assembly 22 rotates synchronously with the bed frame assembly 20. In the process of sliding the mattress frame assembly 22 relative to the bed frame assembly 20, if the mattress 70 is placed on the mattress frame assembly 22, the mattress frame assembly 22 drives the mattress 70 to move in the direction close to or away from the backrest assembly 11.

[0079] When it is needed to lift and fold the bed frame assembly 20, the mattress support assembly 22 is pulled to move the mattress 70 away from the backrest assembly 11, so that there is enough space between the mattress support assembly 22 and the backrest assembly 11 to accommodate the mattress 70, thereby avoiding the mattress 70 being damaged by being pressed. Since the distance between the mattress support assembly 22 and the backrest assembly 11 can be changed by moving the mattress support assembly 22 relative to the bed frame assembly 20, the functional bed 01 can be smoothly turned and folded even if the mattress 70 of different thicknesses is placed on the mattress support assembly 22, and there is always enough space to accommodate the mattress 70 of different thicknesses, thereby avoiding the mattress 70 being damaged by being pressed. Since the mattress support assembly 22 is pulled before the bed frame assembly 20 is turned, the user on the bed can be effectively prompted to leave the functional bed 01, thereby avoiding the user being injured during the turning and folding process. In this way, the same functional bed 01 can be adapted to the mattress 70 of different thicknesses and the mattress 70 of different thicknesses can be avoided being damaged by being pressed during the turning of the mattress support assembly 22 even if the mattress 70 is close to the backrest assembly 11.

[0080] Please refer to Figures 13 to 14 When the functional bed 01 is normally used, the mattress 70 is 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, and to avoid the gap between the mattress 70 and the backrest assembly 11 causing the objects on the bed to fall from the gap to the bed bottom, or being stuck in the structure of the functional bed 01 to damage the functional bed 01. In the case that the mattress 70 is difficult to move, the mattress 70 is easily damaged by being pressed by the mattress support assembly 22 and the backrest assembly 11. Even if the distance between the mattress support assembly 22 and the backrest assembly 11 is designed by calculation to reduce the risk of the mattress 70 being damaged by being pressed, the functional bed 01 can only be adapted to the mattress 70 of one thickness, and cannot be compatible with the mattress 70 of different thicknesses, thereby causing the user to be unable to replace the mattress 70 of different thicknesses. The turning functional bed 01 proposed in the present application can move the mattress support assembly 22 relative to the bed frame assembly 20 by pulling the mattress support assembly 22, thereby changing the distance between the mattress support assembly 22 and the backrest assembly 11. When it is needed to normally use the functional bed 01, the mattress support assembly 22 is pushed when the bed frame assembly 20 is in the use state, so that the mattress 70 of any thickness can be close to the backrest assembly 11. When it is needed to turn and fold the functional bed 01, the mattress support assembly 22 can be pulled to move the mattress support assembly 22 away from the backrest assembly 11, thereby always having enough space between the mattress support assembly 22 and the backrest assembly 11 to accommodate the mattress 70 of different thicknesses, thereby enabling the functional bed 01 to be compatible with the mattress 70 of any thickness, and always avoiding the situation that there is not enough space between the mattress support assembly 22 and the backrest assembly 11 to press the mattress 70. In this way, the same functional bed 01 can be compatible with the mattress 70 of different thicknesses, and the mattress 70 of different thicknesses can be avoided being damaged by being pressed during the turning of the mattress support assembly 22 in any case.

[0081] Please refer to Figures 5 to 9 In some embodiments of the present application, the turnover functional bed 01 further comprises a first positioning device 30, which comprises a first handle assembly 31, a first positioning member 32, and a first connecting assembly 33. The first handle assembly 31 is rotatably installed on the mattress frame assembly 22. The first positioning member 32 is slidably installed 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 matched with the limiting hole 21. During the rotation of 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 needed to rest on the functional bed 01, the functional bed 01 is in the lowered and unfolded state. In this case, the first positioning device 30 is used to position the mattress frame assembly 22 to avoid the mattress frame assembly 22 from sliding relative to the bed frame assembly 20, so that the position of the mattress frame assembly 22 remains stable, and the user can rest on the functional bed 01 safely and comfortably. When it is needed to lift and fold the bed frame assembly 20, 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, and then the mattress frame assembly 22 drives the mattress 70 placed thereon to move away from the bed main body 10, so that there is enough space between the mattress frame assembly 22 and the bed main body 10 to accommodate the mattress 70, thereby avoiding the mattress 70 from being damaged due to being pressed. Since the mattress frame assembly 22 can move relative to the bed frame assembly 20 to change the distance between the mattress frame assembly 22 and the bed main body 10, the functional bed 01 can be smoothly turned over and folded even if the mattress frame assembly 22 is provided with a mattress 70 of different thickness, and there is always enough space to accommodate the mattress 70 of different thickness, thereby avoiding the mattress 70 from being damaged due to being pressed. 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, thereby avoiding injury to the user during the turnover and folding process. In this way, the same functional bed 01 can be adapted to mattresses 70 of different thickness and the safety of the functional bed 01 is ensured.

[0083] When the functional bed 01 is normally used, the first positioning member 32 is partially 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 on the mattress frame assembly 22, thereby connecting the mattress frame assembly 22 and the bed frame assembly 20 through the first positioning member 32, so as to avoid the mattress frame assembly 22 from sliding relative to the bed frame assembly 20, and thereby keep the position of the mattress frame assembly 22 stable, so that the user can rest on the functional bed 01 safely and comfortably.

[0084] When it is needed to lift the bed frame assembly 20 to fold, the positioning of the mattress frame assembly 22 by the first positioning device 30 is released, 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 main body 10 to accommodate the mattress 70, thereby avoiding the mattress 70 being damaged by being pressed, and the functional bed 01 can be compatible with different thicknesses of mattresses 70.

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

[0086] Please refer to Figures 5 to 6 In some embodiments of the present application, the first connecting assembly 33 includes a first connecting line 331 and a first elastic member 335. One end of the first connecting line 331 is fixedly connected with the first handle assembly 31, and the other end of the first connecting line 331 is fixedly connected with the first positioning member 32. The first elastic member 335 is arranged between the first positioning member 32 and the mattress frame assembly 22. In the process of rotating the first handle assembly 31 to the first direction, the first handle assembly 31 pulls the first connecting line 331 to pull the first positioning member 32 through 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 removed from the limiting hole 21. When the first handle assembly 31 is released, the first positioning member 32 is partially inserted into the limiting hole 21 under the action of the elastic force of the first elastic member 335.

[0087] In the process of placing the functional bed 01 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 be flipped to a horizontal state, and the mattress frame assembly 22 is pushed to make the mattress 70 abut against the backrest assembly 11. When the first positioning member 32 reaches the position of the limiting hole 21, the first positioning member 32 is partially inserted into the limiting hole 21 under the action of the elastic force of the first elastic member 335, so that the mattress frame assembly 22 is positioned through the cooperation of the first positioning member 32 and the inner wall of the limiting hole 21, thereby avoiding the mattress frame assembly 22 from sliding relative to the bed frame assembly 20, and thus the position of the mattress frame assembly 22 is kept stable, so that the user can rest on the functional bed 01 stably.

[0088] When it is needed to lift and fold the bed frame assembly 20, the first handle assembly 31 is pulled, and then the first handle assembly 31 pulls the first connecting line 331, so as to pull the first positioning piece 32 through the first connecting line 331 to overcome the elastic force of the first elastic piece 335, so that the first positioning piece 32 is completely moved out of the limiting hole 21, thereby avoiding that the inner wall of the limiting hole 21 hinders the first positioning piece 32, and the mattress frame assembly 22 can be smoothly moved relative to the bed frame assembly 20. In this way, the positioning of the mattress frame assembly 22 at the bed frame assembly 20 is released, so that the mattress frame assembly 22 can be moved relative to the bed frame assembly 20.

[0089] The mattress frame assembly 22 is pulled 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, and then there is enough space between the backrest assembly 11 and the mattress frame assembly 22 to accommodate the mattress 70, so that the mattress 70 is not squeezed and damaged in the process of turning over the bed frame assembly 20. Since the mattress frame assembly 22 can be moved relative to the bed frame assembly 20, the distance between the mattress frame assembly 22 and the backrest is 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 the competitiveness of enterprises.

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

[0091] In the process of pulling the first connecting line 331 by the first handle assembly 31, the first connecting line 331 is pulled as a whole, so that the first handle assembly 31 can smoothly pull the first positioning piece 32. The first connecting line 331 is sleeved in the first wire sleeve 332, and then the first connecting line 331 moves in the first wire sleeve 332, so that the first connecting line 331 is separated from other structures of the functional bed 01 through the first wire sleeve 332, thereby avoiding that the other structures of the functional bed 01 cause blockage and wear of the first connecting line 331, so that the first wire sleeve 332 protects the first connecting line 331, and the process of pulling the first positioning piece 32 by the first handle assembly 31 through the first connecting line 331 is more smooth, thereby ensuring the reliability of the positioning and the release of the positioning of the first positioning piece 32 to the mattress frame assembly 22.

[0092] By fixing the first wire sleeve 332 at least partially with the mattress frame assembly 22, the first wire sleeve 332 is prevented from moving with the first connecting line 331, so that the first connecting line 331 is guided by the inner wall of the first wire sleeve 332, and the movement of the first connecting line 331 is more smooth.

[0093] In some embodiments of the present application, the first connecting line 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 arrangement of the functional bed 01 more reasonable.

[0095] In some embodiments of the present application, the first connecting assembly 33 further comprises a first fixing member 333 and a first guide member 334. The first fixing member 333 is fixedly installed on the mattress frame assembly 22, and is used for fixing the part of the first wire sleeve 332 close to the first handle assembly 31. The first guide member 334 is fixedly installed on the mattress frame assembly 22, and is used for guiding the first positioning member 32. The part of the first wire sleeve 332 close to the first positioning member 32 is fixedly connected with the first guide member 334.

[0096] By fixing the first fixing member 333 on the mattress frame assembly 22 and fixing the first wire sleeve 332 close to the first handle assembly 31 through the first fixing member 333, it is avoided that the first wire sleeve 332 is pulled by the first handle assembly 31 when the first handle assembly 31 pulls the first connecting line 331, thereby ensuring the stability of the positions of the first connecting line 331 and the first wire sleeve 332 and enabling the first connecting line 331 to reliably move relative to the first wire sleeve 332, thereby making the process of pulling the first positioning member 32 by the first handle assembly 31 through the first connecting line 331 more smooth and ensuring the reliability of the positioning and de-positioning of the first positioning member 32 on the mattress frame assembly 22.

[0097] In the process of pulling the first positioning member 32 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 positioning and de-positioning of the first positioning member 32 on 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, the inner wall shape of the guide hole being matched with the outer contour shape of the first positioning member 32.

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

[0100] By connecting the middle vertical support 222 to the middle position of the side frame transverse support 221, when the first connecting line 331 enters the middle vertical support 222 from the side frame transverse support 221, the first connecting line 331 exits the side frame transverse support 221 from the middle position of the side frame transverse support 221. Since the connecting support 224 connects the middle vertical support 222 and the side vertical support 223, the first connecting line 331 in the middle vertical support 222 is bent and then enters the connecting support 224 and reaches the side vertical support 223. Through the above arrangement, the first connecting line 331 is arranged in a transverse "U" shape, so that the first connecting line 331 can pull the first positioning member 32 transversely, so that the first positioning member 32 can move away from the limiting hole 21 located at the side of the bed frame assembly 20, and then the first positioning member 32 can be 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 easily positioned, 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 installed at the middle position of the side frame transverse support 221, and the first guide member 334 is fixedly installed at the side vertical support 223.

[0102] In the process of pulling the first handle assembly 31, the mattress frame assembly 22 can be subjected to a pulling force away from the backrest assembly 11. Pulling the first handle assembly 31 can have two stages of effects: in the first stage, the first handle assembly 31 cannot pull the mattress frame assembly 22 in the process of pulling the first handle assembly 31, so that the first handle assembly 31 rotates relative to the side frame transverse support 221, at which 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, the mattress frame assembly 22 is released from positioning, so that the first handle assembly 31 is continued to be pulled, thereby the first handle assembly 31 can be tightly abutted against the side frame transverse support 221, thereby pulling the mattress frame assembly 22 to move relative to the bed frame assembly 20 away from the backrest assembly 11, so that the distance between the mattress frame assembly 22 and the backrest is adjustable, thereby the functional bed 01 can be compatible with bed 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 bed mattresses 70 of different thicknesses, thereby reducing production costs and improving the competitiveness of enterprises.

[0103] By rotating the first handle assembly 31 to be installed at the middle position of the side frame transverse support 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 conveniently pull the first handle assembly 31; on the other hand, the stress of the mattress frame assembly 22 during being pulled is more uniform, thereby reducing the risk of the mattress frame assembly 22 being blocked by a lateral pulling force, so that the mattress frame assembly 22 can be pulled out more smoothly and reliably.

[0104] Please refer to Figure 4 and Figure 9 In some embodiments of the present application, the first handle assembly 31 comprises a handle rod 311 and a rotating connecting member 312. The rotating connecting member 312 is installed at both ends of the handle rod 311, the rotating connecting member 312 is rotationally connected with the side frame transverse support 221, and one end of the first connecting line 331 is clamped to the rotating connecting member 312. Wherein, pulling the handle rod 311 can make the rotating connecting member 312 rotate relative to the side frame transverse support 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 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, that is, holding the handle rod 311 and pulling the handle rod 311, the handle rod 311 drives the rotating connecting piece 312 to rotate, and then pulls the first connecting line 331 through the rotating connecting piece 312, pulls the first positioning piece 32 through the first connecting line 331, so that the first positioning piece 32 is pulled out to the outside of the limiting hole 21, so that the positioning of the mattress frame assembly 22 is released, and 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 support 221 until it abuts against the frame transverse support 221. Since the handle rod 311 can release the positioning of the mattress frame assembly 22, when the handle rod 311 abuts against the frame transverse support 221, if the handle rod 311 is continuously pulled, the mattress frame assembly 22 can be smoothly pulled out in a 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 avoiding damage to the mattress 70, and 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, allowing users to have more choices, and reducing production costs and improving the competitiveness of enterprises for manufacturers who do not need to design multiple functional beds 01 to adapt to mattresses 70 of different thicknesses.

[0106] Please refer to Figures 9 to 10 In some embodiments of the present application, the rotating connecting pieces 312 are located on both sides of the middle vertical support 222. The frame transverse support 221 is internally provided with a direction changing assembly 40, which 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 connecting piece 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 connecting piece 312. The rotation center axis of the third pulley 43 is perpendicular to the rotation center axis of the rotating connecting piece 312.

[0107] The end of the first connecting line 331 is connected with the rotating connecting piece 312 by clamping, so that the first connecting line 331 can be pulled during the rotation of the rotating connecting piece 312. The first connecting line 331 is led out from the rotating connecting piece 312 and then enters the guiding range of the first pulley 41, so that the arrangement direction of the first connecting line 331 is changed by the first pulley 41, and 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 by 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 by 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 connecting piece 312, when the arrangement direction of the first connecting line 331 is changed by the first pulley 41, the first connecting line 331 is arranged vertically downward, and then reaches the second pulley 42, so that the first connecting line 331 reaches the third pulley 43 after being changed in direction by the second pulley 42, thereby avoiding the risk of the first connecting line 331 falling off from the first pulley 41 when the first connecting line 331 directly reaches the third pulley 43 from the first pulley 41. Since the rotation center axis of the third pulley 43 is perpendicular to the rotation center axis of the rotating connecting piece 312, when the first connecting line 331 is changed in direction by the third pulley 43, the first connecting line 331 is arranged in a horizontal direction and extends along the internal space of the frame transverse support 221 to the middle position of the frame transverse support 221, and then reaches the middle vertical support 222, and then the middle vertical support 222 reaches the connecting support 224, and then is connected with the first positioning piece 32 arranged on the side vertical support 223, so that the first connecting line 331 can pull the first positioning piece 32 transversely, so that the first positioning piece 32 can move away from the limiting hole 21 arranged on the side of the bed frame assembly 20, and then the first positioning piece 32 can be pulled out of the limiting hole 21 by the first handle assembly 31 through the first connecting line 331, and then the positioning of the mattress support assembly 22 is released, so that the mattress support 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 is prevented from being blocked, so that the first handle assembly 31 can pull the first positioning piece 32 through the first connecting line 331, and the reliability of the unlocking process of the positioning of the first positioning piece 32 to the mattress support assembly 22 is ensured.

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

[0110] When it is needed to rest on the functional bed 01, the functional bed 01 is in the laid-out unfolded state, in which case, the first positioning device 30 positions the bed mattress frame assembly 22 to avoid sliding the bed mattress frame assembly 22 relative to the bed frame assembly 20, so that the position of the bed mattress frame assembly 22 remains stable, allowing the user to rest on the functional bed 01 safely and comfortably; at the same time, the second positioning device 50 positions the bed frame assembly 20 to avoid rotating the bed frame assembly 20 relative to the bed main body 10, thereby avoiding the bed frame assembly 20 being mistakenly lifted and folded, ensuring the safety of the user during the rest. When it is needed to lift and fold the bed frame assembly 20, the first positioning device 30 releases the positioning of the bed mattress frame assembly 22, so that the bed mattress frame assembly 22 can move relative to the bed frame assembly 20, thereby moving the bed mattress frame assembly 22 together with the bed mattress 70 placed on the bed mattress frame assembly 22 away from the bed main body 10, so that there is enough space between the bed mattress frame assembly 22 and the bed main body 10 to accommodate the bed mattress 70, thereby avoiding the bed mattress 70 being damaged by being pressed. Since the bed mattress frame assembly 22 can move relative to the bed frame assembly 20 to change the distance between the bed mattress frame assembly 22 and the bed main body 10, the functional bed 01 can be smoothly turned and folded even if different thicknesses of bed mattresses 70 are placed on the bed mattress frame assembly 22, and there is always enough space to accommodate bed mattresses 70 of different thicknesses, avoiding the bed mattress 70 being damaged by being squeezed. After the bed mattress frame assembly 22 together with the bed mattress 70 is pulled away from the bed main body 10, the second positioning device 50 releases the positioning of the bed frame assembly 20, so that the bed frame assembly 20 together with the bed mattress frame assembly 22 is turned and lifted, thereby enabling the functional bed 01 to be smoothly turned and folded. Since there is an action of pulling the bed mattress frame assembly 22 before turning the bed frame assembly 20, the user on the bed can be effectively prompted to leave the functional bed 01, avoiding causing harm to the user during the turning and folding process. In this way, the same functional bed 01 can be adapted to bed mattresses 70 of different thicknesses and the safety of the functional bed 01 is ensured.

[0111] In some embodiments of the present application, the first positioning device 30 comprises a first handle assembly 31, a first positioning member 32, and a first connecting assembly 33. The first handle assembly 31 is rotatably installed on the mattress frame assembly 22. The first positioning member 32 is slidably installed on the mattress frame assembly 22, and 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. During the rotation of 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 needed to rest on the functional bed 01, the functional bed 01 is in the lowered and unfolded state. In this case, the first positioning device 30 positions the mattress frame assembly 22 to avoid the sliding of the mattress frame assembly 22 relative to the bed frame assembly 20, so that the position of the mattress frame assembly 22 remains stable, and the user can rest on the functional bed 01 stably. When it is needed to lift and fold the bed frame assembly 20, the first positioning device 30 releases the positioning of the mattress frame assembly 22, so that the mattress frame assembly 22 can move relative to the bed frame assembly 20, and then the mattress frame assembly 22 drives the mattress 70 placed thereon to move away from the bed main body 10, so that there is enough space between the mattress frame assembly 22 and the bed main body 10 to accommodate the mattress 70, thereby avoiding the damage of the mattress 70 caused by being pressed. Since the distance between the mattress frame assembly 22 and the bed main body 10 can be changed by moving the mattress frame assembly 22 relative to the bed frame assembly 20, the functional bed 01 can be smoothly turned and folded even if the mattress 70 of different thicknesses is placed on the mattress frame assembly 22, and there is always enough space to accommodate the mattress 70 of different thicknesses, thereby avoiding the damage of the mattress 70 caused by being pressed. Since the mattress frame assembly 22 is pulled before the bed frame assembly 20 is turned, the user on the functional bed 01 can be effectively prompted to leave the functional bed 01, thereby avoiding the injury of the user during the turning and folding process. In this way, the same functional bed 01 can be adapted to the mattress 70 of different thicknesses and the safety of the functional bed 01 is ensured.

[0113] When the functional bed 01 is normally used, the first positioning member 32 is partially 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 on the mattress frame assembly 22, thereby connecting the mattress frame assembly 22 and the bed frame assembly 20 through the first positioning member 32, so as to avoid the sliding of the mattress frame assembly 22 relative to the bed frame assembly 20, and to keep the position of the mattress frame assembly 22 stable, thereby enabling the user to rest on the functional bed 01 stably.

[0114] When it is needed to lift and fold the bed frame assembly 20, the positioning of the mattress frame assembly 22 on the bed frame assembly 20 is released by the first positioning device 30, 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 main body 10 to accommodate the mattress 70, thereby avoiding the mattress 70 from being damaged by being pressed, and the functional bed 01 can be compatible with mattresses 70 of different thicknesses.

[0115] In the process of releasing the positioning of the mattress frame assembly 22 on the bed frame assembly 20 by the first positioning device 30, the first handle assembly 31 is pulled, thereby driving the first positioning member 32 to move through the first connecting assembly 33, so that the first positioning member 32 is completely removed from the limiting hole 21, thereby avoiding the inner wall of the limiting hole 21 from hindering the first positioning member 32, so that the mattress frame assembly 22 can move relative to the bed frame assembly 20 smoothly, and thus the positioning of the mattress frame assembly 22 on the bed frame assembly 20 is released.

[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 rotationally installed on the bed frame assembly 20. The second positioning member 52 is slidingly installed 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 installed on the bed main 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] When the mattress frame assembly 22 is pulled out of the bed frame assembly 20 by a desired distance, the second handle assembly 51 can be pulled to rotate the second handle assembly 51 relative to the bed frame assembly 20, thereby pulling the second connecting assembly 53 by the second handle assembly 51 to drive the second positioning member 52 to completely move out of the limiting range of the limiting assembly 54, so as to release the locking of the bed frame assembly 20, so that the bed frame assembly 20 can rotate relative to the bed main body 10, and thus the bed frame assembly 20 is turned and folded together with the mattress frame assembly 22 and the mattress 70, so as to store the functional bed 01. Before the second handle assembly 51 is pulled, 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, so as to avoid the bed frame assembly 20 from rotating relative to the bed main body 10, thereby avoiding the bed frame assembly 20 from being mistakenly lifted and folded, and ensuring the safety of the user during rest.

[0118] In some embodiments of the present application, the second connecting assembly 53 comprises a second connecting wire 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 connecting wire 531 is fixedly connected with the second handle assembly 51, and the other end of the second connecting wire 531 is fixedly connected with 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, the second connecting wire 531 is sleeved in the second wire sleeve 533, and the second connecting wire 531 is movable relative to the second wire sleeve 533. The second fixing member 534 is fixedly installed on the bed frame assembly 20, and is used for fixing 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 is used for guiding the second positioning member 52. The part of the second wire sleeve 533 close to the second positioning member 52 is fixedly connected with the second guide member 535. During the rotation of the second handle assembly 51 to the second direction, the second handle assembly 51 pulls the second connecting wire 531 to pull the second positioning member 52 to overcome the elastic force of the second elastic member 532 through the second connecting wire 531, 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 is partially inserted into the limiting range of the limiting assembly 54 under the action of the elastic force of the second elastic member 532.

[0119] Pulling the second handle assembly 51, and then making the second handle assembly 51 pull the second connecting wire 531, so as to pull the second positioning member 52 through the second connecting wire 531 to make the second positioning member 52 completely move out of the limiting range of the limiting assembly 54, so as to realize the unlocking of the bed frame assembly 20, so that the bed frame assembly 20 can rotate relative to the bed main body 10, and then the bed frame assembly 20 is turned and folded together with the mattress frame assembly 22 and the mattress 70, so as to store the functional bed 01.

[0120] During the pulling of the second connecting wire 531 to the second positioning member 52, the second connecting wire 531 is integrally pulled, so that the second handle assembly 51 can smoothly pull the second positioning member 52. The second connecting wire 531 is sleeved in the second wire sleeve 533, and then the second connecting wire 531 moves in the second wire sleeve 533, so that the second connecting wire 531 is separated from other structures of the functional bed 01 through the second wire sleeve 533, avoiding the blocking and wear of the second connecting wire 531 caused by other structures of the functional bed 01, so that the second wire sleeve 533 protects the first connecting wire 331, and the process of pulling the second positioning member 52 by the second handle assembly 51 through the second connecting wire 531 is more smooth, and the reliability of the positioning and de-positioning of the second positioning member 52 to the bed frame assembly 20 is ensured.

[0121] By fixing the second fixing member 534 to the second wire sleeve 533 close to the second handle assembly 51, and fixing the second fixing member 534 to the bed frame assembly 20, the second wire sleeve 533 is at least partially fixed to the bed frame assembly 20, thereby avoiding the second wire sleeve 533 from moving with the second connecting line 531, and guiding the second connecting line 531 through the inner wall of the second wire sleeve 533, so that the second connecting line 531 moves more smoothly.

[0122] By fixing the second fixing member 534 to the bed frame assembly 20, and fixing the second fixing member 534 to the second wire sleeve 533 close to the second handle assembly 51, the second wire sleeve 533 is prevented from being pulled by the second handle assembly 51 when the second handle assembly 51 pulls the second connecting line 531, thereby ensuring the stability of the position of the second connecting line 531 and the second wire sleeve 533, and allowing the second connecting line 531 to reliably move relative to the second wire sleeve 533, thereby making the process of the second handle assembly 51 pulling the second positioning member 52 through the second connecting line 531 more smooth, and ensuring the reliability of the positioning and de-positioning of the second positioning member 52 to the bed frame assembly 20.

[0123] During the process of the second positioning member 52 being 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 positioning and de-positioning of the second positioning member 52 to the bed frame assembly 20.

[0124] During the process of placing the functional bed 01 into use, the bed frame assembly 20 is turned downward, so that the bed frame assembly 20 drives the mattress frame assembly 22 and the mattress 70 to be flipped to a horizontal state. When the second positioning member 52 reaches the limiting range of the limiting assembly 54, 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, thereby positioning the bed frame assembly 20 through the cooperation of the second positioning member 52 and the limiting assembly 54, avoiding the bed frame assembly 20 from rotating relative to the bed main body 10, thereby avoiding the bed frame assembly 20 from being mistakenly 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, the inner wall shape of the guide hole being adapted to the outer contour shape of the second positioning member 52.

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

[0127] By configuring the second connecting wire 531 and the second wire sleeve 533 as flexible wire type structures, the second connecting wire 531 and the second wire sleeve 533 can adapt to different spatial arrangement, and the installation positions of the second handle assembly 51 and the second positioning member 52 are more flexible, and the spatial structure arrangement of the functional bed 01 is more reasonable.

[0128] Please refer to Figure 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 installed on the bed frame assembly 20. The limiting sliding member 542 is slidingly installed on the limiting fixing member 541, and is provided with a limiting surface. The limiting adjusting member 543 is used to adjust the relative height of the limiting surface and the limiting fixing member 541. When the second positioning member 52 partially extends into the limiting range of the limiting assembly 54, the second positioning member 52 and the limiting sliding member 542 abut at the limiting surface.

[0129] It can be understood 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 surface of the limiting sliding member 542 during the movement of the second positioning member 52 to the limiting assembly 54, so that the second positioning member 52 cannot abut with the limiting sliding member 542 at the limiting surface, and the positioning of the bed frame assembly 20 cannot be realized. 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 extends into the limiting range of the limiting assembly 54, so that there is a loose space between the bed frame assembly 20 and the bed body 10, which affects the positioning effect of the bed frame assembly 20.

[0130] By adjusting the relative height of the limiting surface of the limiting sliding member 542 and the limiting fixing member 541 through the limiting adjusting member 543, the second positioning member 52 can smoothly extend into the limiting range of the limiting assembly 54 and abut with the limiting sliding member 542 at the limiting surface, so as to ensure the reliability of the positioning of the second positioning member 52 to the bed frame assembly 20.

[0131] In some embodiments of the present application, the limiting adjusting member 543 is rotationally installed on the limiting fixing member 541. The connection mode between the limiting adjusting member 543 and the limiting sliding member 542 is configured as threaded connection. During the rotation of the limiting adjusting member 543, under the action of the connecting thread, the limiting adjusting member 543 moves the limiting sliding member 542 relative to the limiting fixing member 541.

[0132] When it is necessary to adjust the height of the limiting surface of the limiting sliding piece 542, the limiting adjusting piece 543 is rotated by a wrench or the like, and then, under the action of the connecting thread, the limiting adjusting piece 543 moves the limiting sliding piece 542 relative to the limiting fixed piece 541, so that the relative height of the limiting surface of the limiting sliding piece 542 and the limiting fixed piece 541 is adjusted, and then the second positioning piece 52 can smoothly extend into the limiting range of the limiting assembly 54 and abut against the limiting sliding piece 542 at the limiting surface, thereby ensuring the reliability of the positioning of the second positioning piece 52 on the bed frame assembly 20.

[0133] Please refer to Figure 4 and Figure 11 In some embodiments of the present application, the functional bed 01 further comprises a guide device 60 for guiding the mattress frame assembly 22 during movement relative to the bed frame assembly 20.

[0134] During 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, so that the relative movement of the mattress frame assembly 22 and the bed frame assembly 20 is smoother and more labor-saving, and the user can move the mattress frame assembly 22 more easily and smoothly.

[0135] In some embodiments of the present application, the guide device 60 comprises a guide rail assembly 61 and a sliding block assembly 62. The guide rail assembly 61 is fixedly installed on the bed frame assembly 20. The sliding block assembly 62 is fixedly installed on the mattress frame assembly 22, and is adapted to the guide rail assembly 61 and is in sliding connection with the guide rail assembly 61.

[0136] Through the cooperation of the sliding rail assembly and the sliding block 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, and 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 comprises a first guide rail piece 611, a second guide rail piece 612 and a limiting stopper 613. The first guide rail piece 611 is fixedly installed on the bed frame assembly 20. The second guide rail piece 612 is fixedly installed on the same side of the bed frame assembly 20 as the first guide rail piece 611. The limiting stopper 613 is fixedly installed on the mattress frame assembly 22. When the mattress frame assembly 22 is pulled out to a first limit position, the limiting stopper 613 abuts against the first guide rail piece 611. When the mattress frame assembly 22 is pushed in to a second limit position, the limiting stopper 613 abuts against the second guide rail piece 612.

[0138] When the mattress frame assembly 22 is pulled out to the first limit position, the relative distance between the mattress frame assembly 22 and the backrest assembly 11 reaches the maximum, and the range of the mattress frame assembly 22 being pulled out is limited by the cooperation between the first guide rail 611 and the limit block 613, so as to avoid the mattress frame assembly 22 from being separated from the bed frame assembly 20, and thus the stability and reliability of the main structure of the functional bed 01 are ensured.

[0139] When the mattress frame assembly 22 is pushed in to the second limit position, the distance between the mattress frame assembly 22 and the backrest assembly 11 reaches the minimum, and at this time, if the mattress 70 is placed on the mattress frame assembly 22, the mattress 70 is in close contact with the backrest assembly 11. The range of the mattress frame assembly 22 being pushed in is limited by the cooperation between the second guide rail 612 and the limit block 613, so as to avoid the mattress frame assembly 22 from colliding with the backrest assembly 11, thus avoiding 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 limit hole 21 is arranged on the sliding block assembly 62.

[0141] By arranging the limit hole 21 on the sliding block assembly 62, the first positioning piece 32 can be positioned with the limit hole 21 after reaching the position of the sliding block assembly 62, so that the first positioning piece 32 does not need to be limited by additional structures, the application of production materials is reduced, the structure of the functional bed 01 is simplified, the production cost of the functional bed 01 is reduced, and the competitiveness of the enterprise is improved.

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

[0143] Pulling the first handle assembly 31 to make all the first positioning pieces 32 move out of the limit hole 21;

[0144] Pulling the mattress frame assembly 22 to make the mattress frame assembly 22 move away from the backrest assembly 11, and thus the bed frame assembly 20 reaches the desired position;

[0145] Rotating the bed frame assembly 20 to make the bed frame assembly 20 rotate together with the mattress frame assembly 22 relative to the bed body 10, and thus the turnover and folding of the turnover functional bed 01 is realized.

[0146] It can be understood that when it is necessary to lift and fold the bed frame assembly 20, the mattress frame assembly 22 is pulled to move the mattress 70 placed together with the mattress frame assembly 22 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 avoiding damage to the mattress 70. Because the mattress frame assembly 22 can move relative to the bed frame assembly 20 to change the distance between the backrest assembly 11, the functional bed 01 can be smoothly turned and folded on the mattress frame assembly 22 with different thicknesses of the mattress 70, and there is always enough space to accommodate different thicknesses of the mattress 70, avoiding the mattress 70 being squeezed and damaged. Because there is an action of pulling the mattress frame assembly 22 before turning the bed frame assembly 20, the user on the bed can be effectively prompted 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 different thicknesses of the mattress 70 and avoids the mattress 70 being squeezed and damaged during the turning process of the mattress frame assembly 22 when the mattress 70 is close to the bed backrest.
