Description

Technical Field

[0001] This utility model belongs to the field of household goods technology, specifically relating to an electric bed with a plastic bed board. 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 an electric bed with a plastic bed board. The fixed plate is made of a grid-structured plastic plate, which is less likely to resonate with the vibrations generated during the operation of the drive components. Furthermore, the discrete structure of the grid can disrupt the resonance conditions, interrupt the transmission path of vibration, and reduce the resonance noise during the operation of the electric bed.

[0005] This utility model provides the following technical solution: An electric bed with a plastic bed board includes a bed frame, a bed board, a lifting assembly, and a drive assembly. The bed frame includes a crossbar, 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 includes a movable plate and a fixed plate. The movable plate is rotatably connected to the fixed plate, and the fixed plate is fixedly connected to the bed frame. The fixed plate is a plastic board with a grid structure.

[0006] The fixed plate is made of a grid-structured plastic board. Compared with solid wood boards, on the one hand, the plastic board is less likely to resonate with the vibration generated by the drive components during operation; on the other hand, the discrete structure of the grid can disrupt the resonance conditions, interrupt the transmission path of vibration, and reduce the resonance noise when the electric bed is running; at the same time, the plastic material and grid design greatly reduce the weight of the bed board, achieving lightweight bed.

[0007] In a preferred embodiment, the fixing plate is integrally molded using an injection molding process. This integral molding process ensures the fixing plate is formed in one piece within the mold, guaranteeing structural integrity and dimensional accuracy. It also simplifies the production process, reduces subsequent processing steps, and improves production efficiency. Furthermore, the integral molding structure enhances the overall stability of the fixing plate, preventing noise or deformation caused by loosening at the joints during use.

[0008] As a preferred embodiment, the fixing plate has pre-drilled mounting holes and pre-embedded nuts in the mounting holes to avoid damage to the fixing plate structure during secondary processing. At the same time, it accurately positions the installation position, improves the assembly accuracy between the fixing plate and the bed frame, and between the fixing plate and the movable plate, reduces vibration and noise caused by assembly gaps, and makes the installation process more convenient and efficient.

[0009] In a preferred embodiment, diagonal reinforcing ribs are provided at the pre-drilled mounting holes in the fixing plate. These ribs divide the rectangular grid at the mounting holes into triangular structures, significantly improving the structural strength and deformation resistance at the openings by utilizing the geometric stability of triangles, thereby extending the service life of the fixing plate.

[0010] In a preferred embodiment, the movable board has a continuous planar structure and is made of multiple layers of wood panels.

[0011] In a preferred embodiment, the fixed plate and / or the movable plate is covered with an outer sleeve.

[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, and the motor end of the push rod motor is connected to the crossbeam through the fixing plate.

[0015] The fixing plate can increase the connection area between the push rod motor and the crossbeam, disperse the impact force of motor vibration on the crossbeam, and reduce the vibration noise caused by localized force concentration on the crossbeam; at the same time, it can enhance the installation stability of the push rod motor and avoid additional noise caused by unstable installation when the motor is working.

[0016] In a preferred embodiment, the motor end of the push rod motor is connected to the fixing plate by a pin, which facilitates installation and disassembly, reduces maintenance costs, and ensures a tight and secure connection.

[0017] 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.

[0018] 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.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: The fixed plate is made of a grid-structured plastic board. Compared with solid wood boards, on the one hand, the plastic board is less likely to resonate with the vibration generated by the drive components during operation; on the other hand, the discrete structure of the grid can disrupt the resonance conditions, interrupt the transmission path of vibration, and reduce the resonance noise when the electric bed is running; at the same time, the plastic material and grid design greatly reduce the weight of the bed board, achieving lightweight bed.

[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 1-5 As shown, this embodiment provides an electric bed with a plastic bed board, 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, a side bar 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 bar 12.

[0026] 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. The fixed board 22 is a plastic board with a grid structure. The movable board 21 is a continuous planar structure and is made of multi-layer wood panels. The bed board 2 is covered with an outer cover 23.

[0027] 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. Furthermore, the continuous surface amplifies this resonance noise, negatively impacting the user experience. In this embodiment, the fixing plate 22 uses a grid-structured plastic board. Compared to solid wood, the plastic board is less prone to resonance with vibrations generated by the drive assembly 4. Additionally, the discrete grid structure disrupts resonance conditions, interrupting the vibration transmission path and reducing resonance noise during the operation of the electric bed. Simultaneously, the plastic material and grid design significantly reduce the bed board's weight, achieving a lightweight bed. This embodiment only improves the fixing plate structure, requiring minimal changes to the original electric bed structure and manufacturing process, facilitating mass production.

[0028] The specific structure of the bed board 2 is as follows: 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, which are fixed on the bed frame 2. The backrest 211 is rotatably connected to the buttock board 221, the thigh board 212 is rotatably connected to the lower buttock board 222, and the lower leg board 213 is rotatably connected to the thigh board 212. The drive assembly 4 cooperates with the lifting assembly 3 to realize the lifting and lowering of the movable board 21.

[0029] The specific structures of the upper buttock plate 221 and the lower buttock plate 222 are as follows: Figure 5 As shown. The upper butt plate 221 and the lower butt plate 222 are integrally molded by injection molding process. The plates have pre-drilled mounting holes 223, and nuts are pre-embedded in the mounting holes 223.

[0030] The injection molding process allows the upper rear plate 221 and the lower rear plate 222 to be formed in one step within the mold, ensuring structural integrity and dimensional accuracy. At the same time, it simplifies the production process, reduces subsequent processing steps, and improves production efficiency. Furthermore, the one-piece molding structure enhances the overall structural stability and prevents noise or deformation caused by loosening at the joints during use.

[0031] During processing, mounting holes 223 are reserved at the connection with the bed frame and movable frame, and nuts are pre-embedded. This can avoid damage to the structure of the fixed plate 22 during secondary processing, and at the same time, accurately position the installation position, improve the assembly accuracy between the fixed plate 22 and other components, reduce vibration and noise caused by assembly gaps, and make the installation process more convenient and efficient.

[0032] To enhance the structural strength at the mounting hole 223, diagonal reinforcing ribs 224 are provided at the mounting hole 223 on the fixing plate 22. The diagonal reinforcing ribs 224 divide the rectangular grid at the mounting hole 223 into a triangular structure. By utilizing the geometric stability of triangles, the structural strength and deformation resistance at the opening are significantly improved, thereby extending the service life of the fixing plate 22.

[0033] like Figure 4 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.

[0034] 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.

[0035] 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.

[0036] 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.

[0037] like Figure 2 and Figure 4 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.

[0038] 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.

[0039] Example 2: The difference between this embodiment and Embodiment 1 is that: Figure 4 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.

[0040] 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.

[0041] In order to ensure that the fixing frame 5 can stably support the bed board 2 and prevent the fixing frame 5 from deforming, shaking or resonating due to force or vibration, and to reduce the noise generated by the fixing frame 5 itself, the fixing frame 5 is made of metal and its height is preferably greater than or equal to 6cm to ensure the vibration isolation effect.

[0042] 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.
