Description
Technical Field
[0001] This utility model belongs to the field of home furnishing technology, specifically relating to an electric bed with a soundproof curtain. Background Technology
[0002] Existing electric beds generate significant vibration and noise from the push-rod motor during lifting and lowering, impacting the user's sleep experience and rest quality. The noise generated by the push-rod motor propagates towards the ground and can be amplified by reflection from the floor. In some cases, due to old or hollow floorboards, the noise is further amplified after reflection, negatively affecting the user's experience. Utility Model Content
[0003] To address the shortcomings of existing technologies, this utility model provides an electric bed with a soundproof curtain. The soundproof curtain is installed at the bottom of the bed frame, forming a closed space under the electric bed. This effectively isolates the noise generated when the drive components are working, prevents dust from entering the bed frame, reduces dust accumulation and wear on components, and also hides the bottom structure of the bed frame, optimizing the visual appearance of the bottom of the product and improving the overall aesthetics of the product.
[0004] This utility model provides the following technical solution: An electric bed with a soundproof curtain 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 frame has a soundproof curtain at its bottom, which includes a bottom surface and an edge. The soundproof curtain is fixed to the bottom of the bed frame via the edge.
[0005] By fixing the soundproof curtain to the bottom of the bed frame, a closed bottom space is formed under the electric bed, which blocks the transmission of noise from the drive components to the ground, thereby reducing the overall noise of the electric bed during operation. It can also effectively prevent external dust from entering the bed frame, reduce dust accumulation and wear on components, and hide the bottom structure of the bed frame, optimize the visual appearance of the bottom of the product, and improve the overall aesthetics of the product.
[0006] In a preferred embodiment, the soundproof curtain has a felt surface on the side closest to the drive assembly. The felt surface faces directly towards the noise source (drive assembly), utilizing the sound-absorbing properties of the felt to absorb the noise generated when the drive assembly is operating, effectively improving the sound insulation effect.
[0007] As a preferred embodiment, the thickness of the soundproof curtain is preferably 3mm to 5mm, which can balance sound insulation performance and usability. While ensuring sufficient structural strength to achieve effective sound insulation, it avoids excessive weight and reduced flexibility due to excessive thickness, ensuring that the soundproof curtain can be stably fixed at the bottom of the bed frame.
[0008] In a preferred embodiment, magnetic strips are provided at the bottom of the bed frame and the top of the side edging, and the soundproof curtain is attracted to the bottom of the bed frame by the magnetic strips.
[0009] The soundproof curtain is secured by magnetic clasps, allowing for quick installation and removal, facilitating after-sales maintenance and cleaning. The magnetic clasps at the bottom of the bed frame and the top of the side panels fit tightly, effectively ensuring the airtightness of the soundproof space beneath the electric bed, preventing noise leakage from gaps and improving sound insulation reliability.
[0010] In a preferred embodiment, the side of the soundproof curtain away from the drive assembly is made of an easy-to-clean fabric. Dust and stains on the surface of the soundproof curtain can be quickly wiped or washed away, reducing the maintenance cost of the soundproof curtain.
[0011] As a preferred embodiment, the easy-to-clean fabric is preferably a TPU composite fabric. TPU composite fabric has waterproof, stain-resistant, and abrasion-resistant properties. Liquid stains can be wiped away directly without frequent washing, making cleaning simple and convenient. It is also not easily deformed after washing and has a long service life.
[0012] As a preferred embodiment, the corners of the bottom surface are recessed to fit the shape of the bed legs, thereby avoiding interference between the soundproof curtain and the bed legs and ensuring that the soundproof curtain fits tightly against the bottom of the bed frame after installation, maintaining the integrity of the enclosed space.
[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, 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.
[0016] 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.
[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: By fixing the soundproof curtain to the bottom of the bed frame, a closed bottom space is formed under the electric bed, which blocks the transmission of noise from the drive components to the ground, thereby reducing the overall noise of the electric bed during operation. It can also effectively prevent external dust from entering the bed frame, reduce dust accumulation and wear on components, and hide the bottom structure of the bed frame, optimize the visual appearance of the bottom of the product, and improve the overall aesthetics of the product.
[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 1-7 As shown, this embodiment provides an electric bed with a soundproof curtain, 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 bottom of the bed frame 1 is equipped with a soundproof curtain 7, the structure of which is as follows: Figure 2 , Figure 4 and Figure 5 As shown, the soundproof curtain 7 includes a bottom surface 71 and a surrounding edge 72. The soundproof curtain 7 is fixed to the bottom of the bed frame 1 through the surrounding edge 72.
[0027] The soundproof curtain 7 is fixed to the bottom of the bed frame 1 by the edge 72, forming a closed bottom space under the electric bed. This blocks the transmission of noise from the drive component 4 to the ground, thereby reducing the overall noise of the electric bed during operation. It can also effectively block external dust from entering the interior of the bed frame 1, reduce dust accumulation and wear on components, and hide the bottom structure of the bed frame 1, optimizing the visual appearance of the bottom of the product and improving the overall aesthetics of the product.
[0028] Specifically: The side of the soundproof curtain 7 closest to the drive component 4 is made of felt, with the felt surface directly facing the noise source (drive component). The sound-absorbing properties of the felt absorb the noise generated when the drive component is working, effectively improving the sound insulation effect. The side of the soundproof curtain 7 away from the drive component 4 is made of easy-to-clean fabric, which can be quickly wiped or washed to remove dust and stains from the surface of the soundproof curtain, reducing the maintenance cost of the soundproof curtain.
[0029] The easy-to-clean fabric is preferably a TPU composite fabric with waterproof, stain-resistant and wear-resistant properties. It is simple and convenient to clean, does not easily deform after washing, and has a long service life.
[0030] In order to balance the sound insulation performance and usability of the soundproof curtain 7, while ensuring sufficient structural strength to achieve effective sound insulation, and avoiding excessive weight and reduced flexibility due to excessive thickness, and ensuring the connection stability between the soundproof curtain 7 and the bed frame 1, the thickness of the soundproof curtain 7 is preferably 3mm to 5mm in this embodiment.
[0031] like Figure 2 As shown in Figure 5, in this embodiment, the connection method between the soundproof curtain 7 and the bottom of the bed frame 1 is as follows: Magnetic plates 8 are installed at the bottom of the crossbar 11 and side bars 12, and a ring of magnetic plates 8 is installed at the top of the edge 72. The soundproof curtain 7 is attracted to the bottom of the bed frame 1 by the magnetic plates 8. The magnetic plates 8 fix the soundproof curtain 7 in place, enabling quick installation and removal of the soundproof curtain 7, facilitating after-sales maintenance and cleaning. The magnetic plates at the bottom of the bed frame 1 and the top of the edge 72 fit tightly, effectively ensuring the airtightness of the soundproof space under the electric bed, preventing noise leakage from gaps, and improving the reliability of sound insulation.
[0032] Furthermore, to avoid interference between the soundproof curtain 7 and the bed legs, and to ensure that the soundproof curtain 7 fits tightly against the bottom of the bed frame 1 after installation and maintains the integrity of the enclosed space, the corners of the bottom surface 71 of the soundproof curtain 7 have a concave structure that matches the shape of the bed legs.
[0033] 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.
[0034] like Figure 5 and Figure 7As 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.
[0035] 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.
[0036] 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.
[0037] 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.
[0038] like Figure 5 and Figure 7 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.
[0039] 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.
[0040] Example 2: The difference between this embodiment and Embodiment 1 is that, as Figures 3-5 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.
[0041] 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.
[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.
