Description

Technical Field

[0001] This utility model belongs to the field of home furnishing technology, specifically relating to an electric frame bed. Background Technology

[0002] Existing electric beds generate significant vibration and noise from the push rod motor during lifting and lowering, affecting the user's sleep experience and rest quality.

[0003] Specifically, bed boards are usually made of multi-layer solid wood panels. The bed board is a continuous plane, and its closed surface is like a "drum surface". It is very easy to resonate with the vibration generated by the motor when it is running. Moreover, the continuous surface will further amplify the resonance noise, affecting the user's experience. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a frame-type electric bed with a frame structure. The bed board adopts a frame structure, which disrupts the resonance conditions, thereby reducing the noise and vibration caused by resonance in the bed board, reducing the overall noise during the operation of the electric bed, and improving the user experience.

[0005] This utility model provides the following technical solution: An electric frame bed includes a bed frame, a bed board, a lifting assembly, and a drive assembly. The bed frame includes crossbars, side bars, and a crossbeam. One end of the drive assembly is connected to the crossbeam, and the other end of the drive assembly is connected to the lifting assembly. The lifting assembly is rotatably connected to the side bars. The bed board adopts a frame structure to reduce resonance.

[0006] Compared to the fully enclosed bed board used in existing technologies (such as solid wood multi-layer boards), the bed board of this utility model adopts a frame structure, which can block the transmission path of vibration and noise generated when the drive components are working, destroy the resonance conditions, thereby reducing the noise and vibration of the bed board caused by resonance, reducing the overall noise during the operation of the electric bed, and improving the user experience.

[0007] In a preferred embodiment, the bed board adopts a steel frame structure. The natural frequency of steel material differs significantly from the vibration frequency of the drive component during operation. Compared to board material, it is less likely to resonate with the vibrations generated by the drive component during operation. Furthermore, the steel frame structure has higher strength, stronger resistance to deformation, and higher durability.

[0008] In a preferred embodiment, the top of the bed board is provided with steel wires at equal intervals. The bed board is used to support the mattress. Since the internal frame of the steel frame bed board is relatively large, placing the mattress directly on the bed board can easily cause the mattress to be suspended and unevenly stressed. The evenly spaced steel wires can provide uniform support for the mattress, avoid local suspension or concentrated stress, prevent the mattress from collapsing, and extend the mattress's lifespan.

[0009] In a preferred embodiment, the steel wire is welded and fixed to the top of the bed board. Fixing the steel wire by welding ensures a firm connection between the wire and the steel bed board, preventing displacement, loosening, or detachment of the wire under stress during use, and maintaining an even distribution of the wires to provide uniform support for the mattress.

[0010] As a preferred embodiment, the spacing of the steel wires is preferably 8cm to 10cm, which is compatible with the distribution density of conventional mattress springs. This ensures that the mattress is evenly supported and avoids the springs being suspended due to excessive spacing, or the mattress board being increased and manufacturing costs being increased due to excessive spacing.

[0011] As a preferred embodiment, the diameter of the steel wire is preferably 2mm to 4mm to meet the load-bearing requirements of supporting the mattress and the user's weight, avoid bending and deformation after long-term use, adapt to welding processes, and ensure the reliability and structural stability of the connection between the steel wire and the bed board.

[0012] In a preferred embodiment, the drive assembly includes a push rod motor and a transmission rod. The motor end of the push rod motor is connected to the crossbeam, the push rod end of the push rod motor is rotatably connected to the transmission rod, and the transmission rod is connected to the lifting assembly.

[0013] The push rod motor drives the lifting assembly through the transmission rod to raise and lower the bed board. The transmission rod acts as a damping medium, disrupting the transmission path of vibrations generated by the push rod motor and effectively reducing the operating noise of the electric bed.

[0014] In a preferred embodiment, a fixing plate is provided on the crossbeam, the motor end of the push rod motor is connected to the crossbeam through the fixing plate, and the motor end of the push rod motor is connected to the fixing plate by a pin.

[0015] The fixing plate increases the connection area between the push rod motor and the crossbeam, dispersing the impact of motor vibration on the crossbeam and reducing vibration noise caused by localized stress concentration. It also enhances the installation stability of the push rod motor, preventing additional noise caused by unstable installation during operation. The motor and fixing plate are connected by pins, facilitating installation and disassembly, reducing maintenance costs, and ensuring a tight and secure connection.

[0016] In a preferred embodiment, a fixing frame is provided between the bed frame and the bed board, and the bed board is connected to the bed frame through the fixing frame, so that there is a certain distance between the drive assembly and the bed board, thereby reducing noise.

[0017] The bed board and bed frame are indirectly connected by a fixed frame, which creates a gap between the drive assembly and the bed board. This gap can prevent the vibration generated by the drive assembly from being directly transmitted to the bed board, thus avoiding the bed board from amplifying noise due to resonance. This further reduces the overall noise during the operation of the electric bed and improves the user experience.

[0018] As a preferred embodiment, support rods are provided at 1 / 3 and 2 / 3 of the width of the bed frame to further enhance the overall load-bearing capacity and structural stability of the bed frame, prevent the relative position of the drive assembly, lifting assembly and bed board from shifting due to bed frame deformation, reduce vibration and noise caused by structural misalignment, and extend the service life of the electric bed.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: Compared to the fully enclosed bed board used in existing technologies (such as solid wood multi-layer boards), the bed board of this utility model adopts a frame structure, which can block the transmission path of vibration and noise generated when the drive components are working, destroy the resonance conditions, thereby reducing the noise and vibration of the bed board caused by resonance, reducing the overall noise during the operation of the electric bed, and improving the user experience.

[0020] To further reduce noise, a fixing frame is installed between the bed board and the bed frame. The fixing frame indirectly connects the bed board and the bed frame, creating a gap between the drive assembly and the bed board. This gap can prevent the vibration generated by the drive assembly during operation from being directly transmitted to the bed board, thus avoiding the bed board from amplifying noise due to resonance.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings: Example 1: like Figures 1-6 As shown, this embodiment provides a frame bed board electric bed, including a bed frame 1, a bed board 2, a lifting assembly 3 and a drive assembly 4.

[0025] The bed frame 1 includes a crossbar 11, side bars 12, and a crossbeam 13; the drive assembly 4 includes a push rod motor 41 and a transmission rod 42, the motor end of the push rod motor 41 is connected to the crossbeam 13, the push rod end of the push rod motor 41 is rotatably connected to the transmission rod 42, the transmission rod 42 is connected to the lifting assembly 3, and the lifting assembly 3 is rotatably connected to the side bars 12; the bed board 2 adopts a steel frame structure, and the bed board 2 is covered by an outer cover.

[0026] In existing technologies, bed boards are typically continuous planes, and their closed surfaces resemble a "drumhead," making them highly susceptible to resonance with vibrations generated by the motor during operation. Furthermore, the continuous surface amplifies this resonance noise, negatively impacting the user experience. In this embodiment, the bed board 2 employs a steel frame structure, which blocks the transmission path of vibrations and noise generated during the operation of the drive components. Moreover, the natural frequency of the steel frame differs significantly from the operating frequency of the push rod motor 41, making it less prone to resonance with the vibrations generated by the push rod motor 41 compared to a board material. This effectively reduces noise and vibration caused by resonance in the bed board, lowers the overall noise level during the operation of the electric bed, and improves the user experience.

[0027] The bed board 2 is used to support the mattress. Because the internal frame of the steel-framed bed board 2 is relatively large, placing the mattress directly on it could easily cause the mattress to be unsupported and experience uneven pressure. Therefore, steel wires 7 are welded at equal intervals to the top of the bed board 2 to provide even support for the mattress, preventing localized unsupported areas or concentrated pressure, thus preventing mattress collapse and extending its lifespan. Fixing the steel wires 7 by welding ensures a secure connection between the wires 7 and the steel bed board, preventing displacement, loosening, or detachment of the wires 7 during use.

[0028] To match the distribution density of springs in a conventional spring mattress and ensure that the mattress is evenly supported, the welding spacing of the steel wire 7 is preferably 8cm~10cm. This avoids the springs being suspended due to excessive spacing, or the mattress board being increased and manufacturing costs being increased due to insufficient spacing.

[0029] Meanwhile, in order to meet the load-bearing requirements of supporting the mattress and the user's weight, and to prevent the steel wire 7 from bending and deforming after long-term use, the diameter of the steel wire 7 is preferably 2mm~4mm, which can also ensure the reliability of the connection between the steel wire 7 and the bed board and the structural stability.

[0030] Furthermore, the specific structure of the bed board 2 is as follows: the bed board 2 includes a movable board 21 and a fixed board 22, the movable board 21 and the fixed board 22 are rotatably connected, and the fixed board 22 is fixedly connected to the bed frame 1; wherein, the movable board includes a backrest 211, a thigh board 212 and a lower leg board 213, the fixed board 22 includes an upper buttock board 221 and a lower buttock board 222, the upper buttock board 221 and the lower buttock board 222 are fixed on the bed frame 2, the backrest 211 and the buttock board 221 are rotatably connected, the thigh board 212 and the lower buttock board 222 are rotatably connected, and the lower leg board 213 and the thigh board 212 are rotatably connected; the drive assembly 4 cooperates with the lifting assembly 3 to realize the lifting and lowering of the movable board 21.

[0031] like Figure 5 and Figure 6 As shown, the drive assembly 4 has two sets: one set is used to drive the backrest 211 to rise and fall, and the other set is used to drive the thigh board 212 and the lower leg board 213 to rise and fall. The lifting assembly 3 includes a swing arm 31 and a roller 32. One end of the swing arm 31 is connected to the roller 32, and the roller 32 is rotatably connected to the bed board.

[0032] The specific process of lifting and lowering the back panel 211 is as follows: the push rod motor 41 works to extend / retract the push rod end, thereby driving the transmission rod 42. The transmission rod 42 drives the swing arm 31 to rotate, and drives the roller 32 to roll on the back panel 211, thereby driving the back panel 211 to lift and lower.

[0033] The lifting and lowering process of the thigh plate 212 is the same as that of the back plate 211. The lifting component 3 is driven by the push rod motor 41 to achieve the lifting, and the lower leg plate 213 is supported by the leg support 6, so that the legs are in a relatively comfortable state when the thigh plate 212 and the lower leg plate 213 are raised and lowered.

[0034] The push rod motor 41 drives the lifting assembly 3 through the transmission rod 42 to achieve the lifting of the bed board. The push rod motor 41 is not directly connected to the lifting assembly 3. The transmission rod 42 acts as a damping medium, which disrupts the transmission path of the vibration generated by the push rod motor 41, and can further reduce the operating noise of the electric bed.

[0035] like Figure 5 and Figure 6 As shown, the connection between the push rod motor 41 and the crossbeam 13 is as follows: a fixing plate 131 is provided on the crossbeam 13, the motor end of the push rod motor 41 is connected to the crossbeam 13 through the fixing plate 131, and the motor end of the push rod motor 41 and the fixing plate 131 are connected by a pin.

[0036] The fixing plate can increase the connection area between the push rod motor 41 and the crossbeam 13, disperse the impact force of the push rod motor vibration on the crossbeam 13, and reduce the vibration noise caused by the local force concentration of the crossbeam 13; at the same time, it can enhance the installation stability of the push rod motor 41 and avoid additional noise caused by unstable installation when the motor is working.

[0037] Example 2: The difference between this embodiment and Embodiment 1 is that: Figure 5 and Figure 6 As shown, a fixing frame 5 is provided between the bed frame 1 and the bed board 2, and the fixing plate 22 is fixedly connected to the fixing frame 5; wherein, the fixing frame 5 is a metal frame, and the height is preferably greater than or equal to 6cm.

[0038] The bed board 2 and the bed frame 1 are indirectly connected by the fixing frame 5, so that there is a gap between the drive component 4 and the bed board 2. This gap can block the vibration generated by the drive component 4 when it is working from being directly transmitted to the bed board 2, and prevent the bed board 2 from further amplifying the noise due to resonance, thereby further reducing the overall noise during the operation of the electric bed and improving the user experience.

[0039] Meanwhile, to further ensure the overall stability of the electric bed and guarantee the stable support of the bed frame 1 to the bed board 2, such as... Figure 6 As shown, support rods 14 are installed at 1 / 3 and 2 / 3 of the width of the bed frame 1.

[0040] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
