Description

Technical Field

[0001] This utility model belongs to the field of home furnishing technology, specifically relating to a low-noise electric 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, when an electric bed is running, the push rod motor will generate vibration and operating noise simultaneously. In the existing technology, the push rod motor is usually directly connected to the bed frame, and the bed board is directly connected to the bed frame. Therefore, the vibration generated by the push rod motor is directly transmitted to the bed board through the bed frame, causing the bed board to resonate and further amplify the noise, affecting the user's experience. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a low-noise electric bed. A fixing frame is installed between the bed board and the bed frame, which indirectly connects the bed board and the bed frame. This creates a gap between the drive component and the bed board, isolating the vibration source from the bed board and thus disrupting the transmission path of noise and vibration. This achieves a low-noise effect for the electric bed and improves the user experience.

[0005] This utility model provides the following technical solution: A low-noise electric 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. 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 to reduce vibration transmission.

[0006] The bed board and the 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 and achieving the low noise effect of the electric bed.

[0007] In a preferred embodiment, the bed board includes a movable plate and a fixed plate, the movable plate being rotatably connected to the fixed plate, and the fixed plate being fixedly connected to the fixing frame.

[0008] The movable board can be raised and lowered by the lifting component to meet the adjustment function of the electric bed; at the same time, the fixed board is fixedly connected to the fixed frame to ensure the connection stability between the bed board and the bed frame, avoid additional vibration and noise caused by loose bed board structure, and further enhance the overall noise reduction effect.

[0009] In a preferred embodiment, the bed frame is provided with a plurality of support structures for supporting the movable board, and the height of the support structures is the same as the height of the fixed frame.

[0010] The fixed frame between the bed frame and the bed board creates a gap between them. To accommodate this gap, multiple support structures of the same height as the fixed frame are installed on the bed frame to provide stable support for the movable board. This ensures that the movable board and the fixed board are on the same plane when the movable board is not raised, thus guaranteeing the overall flatness of the bed board.

[0011] As a preferred embodiment, the height of the fixing frame is preferably greater than or equal to 6cm, so as to effectively block the vibration generated by the drive component from being directly transmitted to the bed board and ensure the vibration isolation effect.

[0012] In a preferred embodiment, the fixing frame is a metal frame, which can stably support the bed board and prevent the fixing frame from deforming, shaking or resonating due to force or vibration, thereby reducing the noise generated by the fixing frame itself.

[0013] 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.

[0014] 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.

[0015] 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.

[0016] 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.

[0017] In a preferred embodiment, the motor end of the push rod motor is connected to the fixing plate by a pin, which ensures a tight connection and prevents loosening.

[0018] In a preferred embodiment, the bed board has a continuous planar structure and is made of multiple layers of wood panels.

[0019] In a preferred embodiment, the bed board is a steel frame structure.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: A fixing frame is installed between the bed board and the bed frame to indirectly connect the bed board and the bed frame. This creates a gap between the drive component and the bed board, which can block the vibration generated by the drive component from being directly transmitted to the bed board. This disrupts the transmission path of noise and vibration, prevents the bed board from amplifying noise due to resonance, reduces noise from the source of vibration transmission, achieves the low-noise effect of the electric bed, and improves the user experience.

[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 a low-noise 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, 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] like Figure 2 As shown, a fixing frame 5 is provided between the bed frame 1 and the bed board 2, and the bed board 2 is connected to the bed frame 1 through the fixing frame 5. The fixing frame 5 achieves an indirect connection between the bed board 2 and the bed frame 1, creating a gap between the drive assembly 4 and the bed board 2. This gap prevents the vibration generated by the drive assembly 4 during operation from being directly transmitted to the bed board 2, avoiding further amplification of noise due to resonance in the bed board 2, thus achieving the low-noise effect of the electric bed. At the same time, the push rod motor 41 drives the lifting assembly 3 through the transmission rod 42 to raise and lower the bed board. The transmission rod 42 and the fixing frame 5 together act as a damping medium, disrupting the transmission path of the vibration generated by the push rod motor 41, further reducing the operating noise of the electric bed.

[0027] like Figure 5 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.

[0028] 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.

[0029] like Figure 1 , Figure 3 and Figure 4 As shown, in this embodiment, the bed board 2 is a continuous planar structure made of multiple layers of wood panels, and the bed board 2 is covered with an outer cover. The bed board 2 includes a movable plate 21 and a fixed plate 22. The movable plate 21 and the fixed plate 22 are rotatably connected, and the fixed plate 22 is fixedly connected to the fixing frame 5.

[0030] 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 the height is preferably greater than or equal to 6cm to ensure the vibration isolation effect.

[0031] like Figure 2 , Figure 3 and Figure 5As shown, the fixed frame 5 between the bed frame 1 and the bed board 2 creates a gap between the bed board 2 and the bed frame 1. In order to adapt the movable board 21 to this gap, multiple support structures 7 with the same height as the fixed frame 5 are set on the bed frame 1 to provide stable support for the movable board 21. When the movable board 21 is not raised, it can ensure that the movable board 21 and the fixed board 22 are on the same plane, thereby ensuring the overall flatness of the bed board 2.

[0032] Furthermore, the specific structure of the bed board 2 is as follows: the movable board includes a back board 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 fixed frame 5; the back board 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.

[0033] like Figure 3 and Figure 5 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] Example 2: The difference between this embodiment and Embodiment 1 is that the bed board 2 is a steel frame structure.

[0037] In Example 1, the bed board 2 is made of multi-layered wood panels, forming a continuous planar structure. This structure is prone to resonance with the vibrations generated during motor operation, leading to further amplification of noise. This example uses a steel frame bed board, effectively disrupting the resonance conditions and reducing resonance, thereby further reducing the overall noise during the operation of the electric bed and improving the user experience.

[0038] 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.
