Description

Technical Field

[0001] The utility model relates to the technical field of furniture, and in particular to a lifting device and a lifting bed thereof. Background Art

[0002] With the development of urbanization, living space has become increasingly valuable. How to make rational use of every inch of land in a limited space has become an important issue in modern home design. As an innovative furniture solution, liftable furniture can provide additional storage space or be converted into a work area without sacrificing comfort, greatly improving the efficiency of space use.

[0003] Traditional lifting furniture often requires a lot of force to operate, which may pose a barrier to use for the elderly, children or users with weak physical strength. Therefore, designing a labor-saving lifting device and introducing advanced mechanical structure and intelligent control system can significantly reduce the difficulty of operation, making the use of lifting furniture more convenient and safer.

[0004] The lift bed in the existing lift furniture generally fixes the driving device in the middle of the bed frame, and uses the crossbeams of the bed frame and other parts as the support of the driving device. After long-term use, the reaction force generated by the driving device on the bed frame may cause wear and loosening of the bed frame. Long-term use and pressure may cause the bed frame to deform or lose stability. At the same time, using the crossbeams of the bed frame as the support of the driving device may cause noise and vibration, affecting the comfort of the user. Utility Model Content

[0005] In view of the problem that the driving device of lifting furniture in the prior art needs to provide a large initial driving force to push the furniture up and down, and at the same time will exert a large reaction force on the furniture, resulting in poor stability of the furniture itself, the utility model proposes a lifting device and a lifting bed thereof, which are used to solve the above technical problems.

[0006] According to the first aspect of the present application, a lifting device is proposed, including a driving device and a lifting bracket, the lifting bracket including a rotating shaft and a swing arm and a connecting part fixed to the rotating shaft, the swing arm is located on both sides of the connecting part; the driving device is rotatably connected to the connecting part, and drives the connecting part upward to drive the swing arm to rotate around the rotating shaft.

[0007] By adopting the above technical solution, with the help of the configuration of the rotating shaft, the swing arm can rotate on the rotating shaft, which allows the swing arm to adjust the angle as needed, providing greater flexibility and adaptability. The swing arms are located on both sides of the connection part. This symmetrical layout helps to balance the distribution of load and force during the lifting process. The uniform force distribution reduces the stress on the structure, thereby enhancing the stability and durability of the entire lifting bracket.

[0008] In some specific embodiments, the driving device includes a gas rod and a driving base, the gas rod includes a fixed part and a piston part, the piston part is slidably arranged in the fixed part, and the fixed part and the piston part are rotatably connected to the driving base and the connecting part respectively.

[0009] By adopting the above technical solution, using the gas rod as the power source for lifting, combined with the design of the driving base, the stability and reliability during the lifting process can be ensured. The fixed part of the gas rod is rotatably connected to the driving base, so that the gas rod can maintain a stable position and direction during the lifting process, thereby providing consistent support force and motion control. The rotating connection design between the gas rod and the driving base allows the gas rod to adjust the angle within a certain range, which increases the adaptability and flexibility of the lifting bed. The rotating connection between the piston part and the connecting part of the gas rod allows the piston to flexibly adjust its movement direction when pushing or pulling. This flexibility allows the gas rod to more effectively adapt to and adjust to different working positions, thereby improving the adaptability and versatility of the overall equipment. Under high load or complex operating conditions, the rotating connection can provide additional stability. The capacity of the piston part can adapt to the working requirements at different angles, which helps to balance the load and reduce unexpected mechanical shock or overload, thereby enhancing the safety of the overall operation.

[0010] In some specific embodiments, the driving base includes a fixed plate and a rotating connecting member, the rotating connecting member is detachably fixed to the fixed plate by bolts, and the rotating connecting member is rotatably connected to the fixed portion.

[0011] By adopting the above technical solution, since the rotating connection can be detachably fixed to the fixing plate by bolts, such a design provides higher structural flexibility, which means that when the rotating connection needs to be repaired, replaced or adjusted, it can be easily disassembled without replacing or significantly modifying the entire driving base, making the assembly and installation process of the driving base more efficient.

[0012] In some specific embodiments, L-shaped connecting pieces are further provided on both sides of the driving base, and holes for bolts to pass through are provided on both sides of the L-shaped connecting piece.

[0013] By adopting the above technical solution, the L-shaped connector provides additional support and stability through its unique shape, and the holes on both sides of the L-shaped connector can be used to connect the driving base to the furniture that needs to be installed with the lifting device, so that the connection between the driving base and the furniture is more stable. Through the geometric design of the L-shaped connector, the force during the lifting process can be more effectively transmitted and dispersed, thereby improving the mechanical efficiency of the entire lifting device.

[0014] In some specific embodiments, a roller is rotatably provided at the end of the swing arm.

[0015] By adopting the above technical solution, the roller can reduce the direct friction between the roller and the contact surface when the lifting bracket pushes the furniture up or down. This friction reduction effect helps to smooth the movement of the furniture, making the lifting action smoother, while also reducing noise during operation.

[0016] According to the second aspect of the present application, a lifting bed is proposed, including a bed body and the above-mentioned lifting device, a flippable bed board is provided on the bed body, a lifting bracket is rotatably connected to the bed body under the bed board, a driving device is fixed to the bottom of the bed body, and the driving device pushes the lifting bracket upward to rotate, the lifting bracket resists the lower surface of the bed board and pushes the bed board to lift.

[0017] By adopting the above technical solution, the support point of the driving device is set at the bottom of the bed, so that the reaction force generated by the driving device when working is transmitted to the ground through the bed, thereby reducing the reaction force borne by the bed itself. Since the lifting bracket directly presses against the lower surface of the bed board and pushes the bed board to lift, this direct physical support can ensure the stability and safety of the bed board during the lifting process, and reduce the possibility of shaking or deviation of the bed board during use.

[0018] In some specific embodiments, the lifting bracket is rotatably disposed on the bed body or the first bed foot, and the first bed foot is detachably fixed to the inner side of the bed body.

[0019] By adopting the above technical solution, the lifting bracket is directly set on the bed body, or is detachably fixed to the bed body through the first bed foot. The detachable structure of the first bed foot is more conducive to the disassembly of the lifting bracket. When the driving device needs maintenance, it can be maintained and replaced by simply disassembling the first bed foot.

[0020] In some specific embodiments, the bed board includes a first bed board and a second bed board rotatably connected together by a hinge, and the second bed board is arranged above the lifting bracket.

[0021] By adopting the above technical solution, the first bed board and the second bed board are connected by hinges, so that one part of the bed board can be raised or lowered independently of the other part, providing a high degree of adjustability.

[0022] In some specific embodiments, the bed body is provided with a cross stabilizing member between the lifting bracket and the bed board, and the end points of the cross stabilizing member are detachably connected to the bed body.

[0023] By adopting the above technical solution, the cross stabilizer serves as an additional supporting structure and is located between the lifting bracket and the bed board, which can significantly enhance the overall stability of the bed. This design helps to disperse and withstand the pressure from the lifting bracket and the bed board, especially when the bed board is adjusted to different angles, ensuring that the bed will not be deformed or damaged due to concentrated pressure.

[0024] In some specific embodiments, a stabilizing bed leg is provided at the bottom of the intersection of the cross stabilizing member, and a fastening groove matching the size of the cross stabilizing member is provided at the top of the stabilizing bed leg.

[0025] By adopting the above technical solution, the stable bed legs serve as the basic support of the bed body. By being arranged at the intersection of the cross stabilizing members, the weight and pressure of the bed body can be effectively dispersed to the ground, thereby enhancing the overall stability of the bed body. This design helps to prevent the bed body from shaking or tilting during use by the user. The fastening grooves are adapted to the size of the cross stabilizing members, ensuring a tight connection between the stable bed legs and the cross stabilizing members, which not only makes the connection between the bed legs and the stabilizing members more secure, but also helps to maintain the integrity and consistency of the bed structure.

[0026] Compared with the prior art, the beneficial effects of this application are:

[0027] The present application mainly solves the problem in the prior art that the driving device of lifting furniture needs to provide a large initial driving force to push the furniture up and down, and at the same time exerts a large reaction force on the furniture, resulting in poor stability of the furniture itself. The present application proposes a lifting device and a lifting bed thereof. Through the reasonable layout of the driving device and the lifting bracket at the bottom of the bed, the stability of the bed during the lifting process is enhanced. In addition, the design of the lifting bracket directly against the lower surface of the bed board and pushing the bed board to lift ensures the stability and safety of the bed board during the lifting process, and reduces the possibility of shaking or deviation of the bed board during use; the rotating connection design of the gas rod and the lifting bracket, and the segmented design of the bed board (the first bed board and the second bed board are connected by hinges) allow the bed to adjust the lifting angle and height in different situations, providing greater flexibility and adaptability; by adding a cross stabilizer and a stabilizing bed leg between the bed body and the lifting bracket, the overall structural strength and stability of the bed body are further enhanced, and the design of the fastening groove makes the connection between the stabilizing bed leg and the cross stabilizer more secure, which helps to maintain the integrity and consistency of the bed structure; the lifting device of the present application is not only limited to the lifting of lifting beds, but can also be used for other furniture that requires lifting functions (such as sofas, seats, etc.).

DETAILED DESCRIPTION

[0036] In the following detailed description, reference is made to the accompanying drawings, which form a part of the detailed description and are shown by illustrative specific embodiments in which the present invention can be practiced. To this end, directional terms, such as "top", "bottom", "left", "right", "up", "down", etc., are used with reference to the orientation of the figures described. Because the components of the embodiments can be positioned in several different orientations, directional terms are used for the purpose of illustration and are by no means limiting. It should be understood that other embodiments may be utilized or logical changes may be made without departing from the scope of the present invention. Therefore, the following detailed description should not be adopted in a limiting sense, and the scope of the present invention is defined by the appended claims.

[0037] According to a first aspect of the present application, a lifting device is provided. Figure 1 A structural schematic diagram of a lifting device according to an embodiment of the utility model is shown. As shown in the figure, the lifting device includes a driving device 01 and a lifting bracket 02. The lifting bracket 02 includes a rotating shaft 021 and a swing arm 022 and a connecting portion 023 fixed to the rotating shaft 021. The swing arm 022 is located on both sides of the connecting portion 023. The driving device 01 is rotatably connected to the connecting portion 023, and drives the connecting portion 023 upward to drive the swing arm 022 to rotate around the rotating shaft 021.

[0038] By means of the configuration of the rotating shaft 021, the swing arm 022 can rotate on the rotating shaft 021, which allows the swing arm 022 to adjust its angle as needed, providing greater flexibility and adaptability. The swing arm 022 is located on both sides of the connecting portion 023. This symmetrical layout helps to balance the load and force distribution during the process of lifting furniture components. The uniform force distribution reduces the stress on the structure, thereby enhancing the stability and durability of the entire lifting bracket 02.

[0039] In a specific embodiment, the driving device 01 includes a gas rod 011 and a driving base 012, the gas rod 011 includes a fixed part 013 and a piston part 014, the piston part 014 is slidably arranged in the fixed part 013, and the fixed part 013 and the piston part 014 are rotatably connected to the driving base 012 and the connecting part 023 respectively.

[0040] Using the gas rod 011 as the power source for lifting, combined with the design of the driving base 012, can ensure the stability and reliability of the furniture lifting process. The fixed part 013 of the gas rod 011 is rotatably connected to the driving base 012, so that the gas rod 011 can maintain a stable position and direction during the lifting process, thereby providing consistent support force and motion control. The rotating connection design between the gas rod 011 and the driving base 012 allows the gas rod 011 to adjust the angle within a certain range, which increases the adaptability and flexibility of the lifting device. The rotating connection between the piston part 014 of the gas rod 011 and the connecting part 023 allows the piston 014 to flexibly adjust its movement direction when pushing or pulling. This flexibility allows the gas rod 011 to adapt and adjust to different working positions more effectively, thereby improving the adaptability and versatility of the overall equipment. Under high load or complex operating conditions, the rotating connection can provide additional stability. The capacity of the piston part 014 can adapt to the working requirements at different angles, help balance the load, reduce unexpected mechanical shock or overload, and thus enhance the safety of the overall operation.

[0041] In a specific embodiment, the driving base 012 includes a fixing plate 015 and a rotating connecting member 016 . The rotating connecting member 016 is detachably fixed to the fixing plate 015 by bolts, and the rotating connecting member 016 is rotatably connected to the fixing portion 013 .

[0042] Since the rotating connection member 016 can be detachably fixed to the fixing plate 015 by bolts, such a design provides higher structural flexibility, which means that when the rotating connection member 016 needs to be repaired, replaced or adjusted, it can be easily disassembled without replacing or significantly modifying the entire driving base 012, making the assembly and installation process of the driving base 012 more efficient.

[0043] In a specific embodiment, L-shaped connecting pieces 017 are further provided on both sides of the driving base 012 , and holes for bolts to pass through are provided on both sides of the L-shaped connecting piece 017 .

[0044] The L-shaped connector 017 provides additional support and stability through its unique shape. The holes on both sides of the L-shaped connector 017 can be used to connect the driving base 012 to the furniture that needs to be installed with the lifting device, making the connection between the driving base 012 and the furniture more stable. Through the geometric design of the L-shaped connector 017, the force during the lifting process can be more effectively transmitted and dispersed, thereby improving the mechanical efficiency of the entire lifting device.

[0045] In a specific embodiment, a roller 024 is rotatably provided at the end of the swing arm 022 .

[0046] The roller 024 can reduce direct friction with the contact surface when the lifting bracket 02 pushes the furniture up or down. This friction reduction effect helps to smooth the lifting and lowering of the furniture, making the lifting action smoother and also reducing noise during operation.

[0047] In a specific embodiment, the length ratio between the swing arm 022 and the connecting part 023 is 3:1. A suitable length ratio can enable the swing arm 022 to have a larger torque. The length ratio of 3:1 means that the torque ratio between the swing arm 022 and the connecting part 023 is 3:1. When the driving force is small, a larger torque can be generated, thereby making it easier to lift the furniture.

[0048] Furthermore, when the lifting device is in an initial state, the angle between the gas rod 011 and the connecting portion 23 is 140°. The larger initial angle enables the gas rod 011 to provide the initial driving force required to drive the lifting bracket 02 to rotate, thereby making it easier to lift the furniture.

[0049] Furthermore, when the lifting bracket 02 of the lifting device is lifted to the maximum height, the angle between the gas rod 011 and the connecting part 023 is 73°. During the lifting process, the angle between the two gradually changes from an obtuse angle to an acute angle. This angle setting can maximize the thrust of the gas rod 011 and improve the lifting efficiency and stability. The reasonably set starting angle and end angle optimize the force transmission and torque change from the perspective of driving force, thereby improving the efficiency and stability of the lifting bracket 02 and extending the service life of the gas rod 011.

[0050] The utility model provides a lifting bed. Figure 2A schematic diagram of the structure of a lifting bed according to an embodiment of the utility model is shown. As shown in the figure, the lifting bed includes a bed body 03 and the above-mentioned lifting device. A reversible bed board 04 is provided on the bed body. The rotating shaft 021 of the lifting bracket 02 is rotatably connected to the bed body 03 below the bed board 04. The driving device 01 is fixed at the bottom of the bed body 03, and the driving device 01 pushes the lifting bracket 02 upward to rotate. The lifting bracket 02 abuts against the lower surface of the bed board 04 and pushes the bed board 04 to lift. By setting the support point of the driving device 01 at the bottom of the bed body 03, the reaction force generated by the driving device 01 when working is transmitted to the ground through the bed body 03, thereby reducing the reaction force borne by the bed body 03 itself. Since the lifting bracket 02 directly abuts against the lower surface of the bed board 04 and pushes the bed board 04 to lift, this direct physical support can ensure the stability and safety of the bed board 04 during the lifting process, and reduces the possibility of shaking or deviation of the bed board 04 during use.

[0051] In a specific embodiment, the rotating shaft 021 of the lifting bracket 02 is rotatably set on the bed body 03 or the first bed foot 025, and the first bed foot 025 is detachably fixed to the inner side of the bed body 03. The lifting bracket 02 is directly set on the bed body 03, or is detachably fixed to the bed body 03 through the first bed foot 025. The detachable structure of the first bed foot 025 is more conducive to the disassembly of the lifting bracket 02. When the lifting device needs maintenance, it can be maintained and replaced by simply disassembling the first bed foot 025.

[0052] Furthermore, for a large-sized bed body 03, two connecting parts 023 can be provided on the rotating shaft 021, and two driving devices 01 are provided corresponding to the connecting parts 023. When the size of the bed body 03 and the matching bed board 04 is large, the driving force that can be provided by a single driving device 01 cannot meet the driving force required for the large-sized lifting bed. The double connecting part 023 combined with the double driving device 01 can meet the needs of the large-sized lifting bed. The cooperation of the double connecting part 023 can reduce the driving force required to be provided by a single gas rod 011, which makes the structure of the double gas rod 011 more labor-saving.

[0053] Figure 3 FIG. 1 shows a schematic diagram of a bed board structure according to a specific embodiment of the utility model. Figure 1-3 As shown, the bed board 04 includes a first bed board 041 and a second bed board 042 which are rotatably connected together by a hinge. The second bed board 042 is arranged above the lifting bracket 02. The first bed board 041 and the second bed board 042 are connected by a hinge, so that one part of the bed board 04 can be raised or lowered independently of the other part, providing a high degree of adjustability.

[0054] Figure 4 A schematic diagram of a bed structure according to a specific embodiment of the utility model is shown. Figure 5FIG. 2 shows a schematic diagram of a stable bed leg structure according to a specific embodiment of the utility model. Figure 1-5 As shown, the bed body 03 is provided with a cross stabilizing member 05 between the lifting bracket 02 and the bed board 04. The end points of the cross stabilizing member 05 are detachably connected to the bed body 03. The cross stabilizing member 05 serves as an additional supporting structure and is located between the lifting bracket 02 and the bed board 04. It can significantly enhance the overall stability of the bed body 03. This design helps to disperse and withstand the pressure from the lifting bracket 02 and the bed board 04, especially when the bed board 04 is adjusted to different angles, to ensure that the bed body 03 will not be deformed or damaged due to concentrated pressure.

[0055] In some specific embodiments, a stabilizing bed leg 06 is provided at the bottom of the intersection of the cross stabilizing member 05, and a fastening groove 07 that matches the size of the cross stabilizing member 05 is provided at the top of the stabilizing bed leg 06. The stabilizing bed leg 06 serves as the basic support of the bed body 03. By being provided at the intersection of the cross stabilizing member 05, the weight and pressure of the bed body 03 can be effectively dispersed to the ground, thereby enhancing the overall stability of the bed body 03. This design helps to prevent the bed body 03 from shaking or tilting during use by the user. The fastening groove 07 matches the size of the cross stabilizing member 05, ensuring a tight connection between the stabilizing bed leg 06 and the cross stabilizing member 05, which not only makes the connection between the two more secure, but also helps to maintain the integrity and consistency of the structure of the bed body 03.

[0056] Furthermore, for a small-sized bed 03, the cross stabilizer 05 is a cross-shaped structure, and for a large-sized bed 03, the cross stabilizer 05 is a swastika-shaped structure. Selecting cross stabilizers 05 of different structures according to different sizes of beds 03 can ensure that sufficient stable support is provided for the bed 03.

[0057] The lifting device of the present application is not limited to the lifting of the above-mentioned lifting bed, but can also be used for other furniture that requires a lifting function, such as the lifting of sofa legs, the lifting of seats, etc.

[0058] The lifting bed of the present application has enhanced stability of the bed body 03 during the lifting process through the reasonable layout of the driving device 01 and the lifting bracket 02 at the bottom of the bed body 03. In addition, the design of the lifting bracket 02 directly against the lower surface of the bed board 04 and pushing the bed board 04 to lift ensures the stability and safety of the bed board 04 during the lifting process, and reduces the possibility of shaking or deviation of the bed board 04 during use; the rotating connection design of the gas rod 011 and the lifting bracket 02, and the segmented design of the bed board 04 (the first bed board 041 and the second bed board 042 are connected by hinges) allow the bed body 03 to adjust the lifting angle and height in different situations, providing greater flexibility and adaptability; by adding a cross stabilizer 05 and a stabilizing bed leg 06 between the bed body 03 and the lifting bracket 02, the overall structural strength and stability of the bed body 03 are further enhanced, and the design of the fastening groove 07 makes the connection between the stabilizing bed leg 06 and the cross stabilizer 05 more secure.
