Description

Technical Field

[0001] This utility model relates to the field of bedding, specifically to a bed frame. Background Technology

[0002] Existing bed frames include a frame, a support assembly mounted on the frame, and a drive assembly that actuates the support assembly. The drive assembly includes a motor and a push rod. The push rod extends and retracts under the motor's drive, thereby actuating the movable parts on the support assembly. This allows the support surface profile formed on the top surface of the support assembly to deform as needed, catering to the user's differentiated support needs in various scenarios. However, the high-speed rotation of the motor generates noise due to vibration and friction, which can affect the user's sleep and impact the user experience. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a bed frame with a noise reduction box. The noise reduction box, which encloses the motor, effectively isolates the noise generated by the motor from being transmitted outward, thereby reducing the impact on the user's sleep and improving the user experience.

[0004] This utility model is achieved through the following method: a bed frame with a noise reduction box, comprising a frame body, a support component mounted on the frame body, and a drive component that drives the support component to move. The drive component includes a motor. The frame body is provided with a noise reduction box that completely encloses the motor. The noise reduction box has a multi-layer structure, including a sound-absorbing layer, a vibration-damping layer, and a sound-insulating layer nested from the inside out, to limit the transmission of noise generated by the motor. The multi-layered noise reduction box effectively isolates the transmission of noise generated by the motor and effectively absorbs the vibration generated by the motor, thereby reducing the impact on the user's sleep and improving the user experience. The sound-absorbing layer absorbs the noise generated by the motor, the vibration-damping layer effectively eliminates the vibration generated by the motor, and the sound-insulating layer effectively prevents the transmission of noise generated by the motor. The multi-layered structure provides multiple noise reduction functions, effectively improving the noise reduction effect.

[0005] Preferably, the support assembly includes a fixed part that is fixedly connected to the frame and a movable part that can move relative to the fixed part. The motor drives the movable part to move via a push rod. The fixed part is fixed to the frame and provides support for the movable part. The movable part can move relative to the fixed part, thereby changing the contour of the support surface to meet the user's different support needs. The motor drives the movable part to move via the push rod, ensuring that the movable part can be freely adjusted along a preset path.

[0006] Preferably, the noise-reducing box has a receiving cavity with an opening at the top. The noise-reducing box is placed over the motor from bottom to top through the opening and is fixedly connected to the fixing part, so that the motor is completely enclosed. The receiving cavity provides space for the motor, and the noise-reducing box is fixed to the fixing part and completely encloses the motor. This ensures that the motor is completely hidden in the receiving cavity, and the fixing part seals the opening to prevent noise from being transmitted outward. It also facilitates disassembly and maintenance, and improves the user experience.

[0007] Preferably, the periphery of the cavity extends outward to form a flange, which is fitted and fixed to the bottom surface of the fixing part. The flange is formed by folding outward from the periphery of the cavity and is fitted and fixed to the fixing part, which not only improves the reliability of the connection, but also improves the sound insulation effect by increasing the width of the contact area, preventing noise from propagating outward through the cavity.

[0008] Preferably, a noise-absorbing gap is provided between the inner wall of the receiving cavity and the outer wall of the motor. The size of the receiving cavity is larger than the size of the motor, which not only facilitates the insertion of the motor into the receiving cavity, but also effectively eliminates noise through the reserved noise-absorbing gap. Noise is reflected back and forth within the reserved gap and consumes energy, thus dissipating noise.

[0009] Preferably, a perforation is formed in the side wall of the noise reduction box. The drive end of the push rod is connected to a motor, and the telescopic end passes through the perforation and is rotatably connected to the movable part. The telescopic end, driven by the motor, drives the movable part to move through its extension and retraction. The drive end of the push rod is connected to the motor to receive the driving force from the motor, and the telescopic end extends outward through the perforation and connects to the movable part to drive the movable part to move.

[0010] Preferably, the perforation is a vertically elongated strip, providing space for the push rod to swing vertically. Since the position of the drive end of the push rod is fixed, the telescopic end moves in conjunction with the movable part during extension and retraction. This allows the telescopic end of the push rod to not only extend and retract along its length but also swing vertically. By setting the perforation to a vertically elongated strip, the push rod can swing vertically while the position of the drive end remains unchanged, ensuring that the telescopic end of the push rod moves synchronously with the movable part, effectively guaranteeing the normal use of the push rod.

[0011] Preferably, the frame includes a crossbar for connecting the drive end of the push rod. The motor is mounted at the drive end of the push rod. The cavity opening edge has a clearance notch, into which the crossbar is inserted. The cavity opening edge is fitted and fixed to the bottom surface of the fixing part to eliminate gaps between the noise reduction box and the fixing part. The crossbar serves both to enhance the structural strength of the frame and to fix the drive end of the push rod, ensuring that the position of the drive end of the push rod remains unchanged. The cavity opening avoids the crossbar through the clearance notch, ensuring that the noise reduction box can be firmly connected to the fixing part, and also reducing outward noise by wrapping the crossbar with the clearance notch.

[0012] Preferably, the sound-absorbing layer is made of sound-absorbing sponge material, which effectively improves the noise absorption effect.

[0013] Preferably, the damping layer is made of aluminum foil damping material. The damping layer eliminates vibration through its own deformation, thereby preventing the vibration from being transmitted outward.

[0014] Preferably, the sound insulation layer is made of sound-damping felt material, which uses its internal gaps to prevent noise from being transmitted outward.

[0015] Preferably, the fixing part comprises a lumbar support plate and a hip support plate positioned front and rear, respectively. The movable part includes a back support plate that swings and connects to the front edge of the lumbar support plate and a thigh plate that swings and connects to the rear edge of the hip support plate. The driving assembly consists of two sets, each driving the back support plate and thigh plate to swing independently. Both the back support plate and thigh plate swing along a preset path, making the range of motion of the corresponding push rod controllable and ensuring precise control. The back support plate and thigh plate use independent driving assemblies, allowing them to operate independently and ensuring that their movements do not interfere with each other.

[0016] The beneficial effects of this utility model are as follows: The noise reduction box that surrounds the motor has a multi-layer structure, which can effectively isolate the noise generated by the motor from being transmitted outward, and can also effectively absorb the vibration generated by the motor operation, thereby reducing the impact on the user's sleep and improving the user experience.

[0024] The essential features of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0025] like Figure 1 , 2 As shown in Figure 3, a bed frame with a noise-reducing box includes a frame body 1, a support assembly mounted on the frame body 1, and a drive assembly that drives the support assembly. The drive assembly includes a motor 2. The frame body 1 is provided with a noise-reducing box 3 that completely encloses the motor 2. The noise-reducing box 3 has a multi-layer structure, including a sound-absorbing layer 4, a vibration-damping layer 5, and a sound-insulating layer 6 arranged sequentially from the inside out, to limit the transmission of noise generated by the motor 2. The noise-reducing box 3, which encloses the motor 2 and has a multi-layer structure, can effectively isolate the noise generated by the motor 2 from transmission and effectively absorb the vibration generated by the motor 2, thereby reducing the impact on the user's sleep and improving the user experience.

[0026] In actual operation, the noise reduction box 3 has a multi-layer structure, including a sound-absorbing layer 4, a vibration-damping layer 5, and a sound-insulating layer 6, each layer serving a different function. Specifically, the noise generated by the motor 2 includes noise generated by internal friction and noise generated by the impact of surrounding components after vibration is transmitted outward. The sound-absorbing layer 4 is made of sound-absorbing sponge material to absorb the noise generated by the motor 2; the vibration-damping layer 5 is made of aluminum foil damping material to eliminate vibrations generated by the motor 2; and the sound-insulating layer 6 is made of sound-insulating damping felt material to prevent the noise generated by the motor 2 from being transmitted outward. This multi-layer structure provides multiple noise reduction functions, effectively improving the noise reduction effect.

[0027] In actual operation, the support assembly includes a fixed part fixed to the frame 1 and a movable part that can move relative to the fixed part. The motor 2 drives the movable part to move through the push rod 8. The fixed part consists of a lumbar support plate 12 and a hip support plate 13, which are separated front and rear. The movable part includes a back support plate 15 that is swayingly connected to the front edge of the lumbar support plate 12 and a thigh plate 14 that is swayingly connected to the rear edge of the hip support plate 13. The drive assembly consists of two sets, which drive the back support plate 15 and the thigh plate 14 to swing independently, respectively. The rear edge of the back support plate 15 is connected to the front edge of the lumbar support plate 12 through a pivot, so that the back support plate 15 can swing around the front edge of the lumbar support plate 12. The front edge of the thigh plate 14 is connected to the rear edge of the hip support plate 13 through a pivot, so that the hip support plate 13 can swing around the rear edge of the hip support plate 13. The drive assembly consists of two sets (e.g., Figure 6 (As shown) and are respectively used to drive the back support plate 15 and the thigh plate 14 to move within a preset range of motion, ensuring that the two can be driven by the corresponding drive components, effectively improving the movement accuracy of the back support plate 15 and the thigh plate 14, and ensuring that the support surface contour meets the user's differentiated usage requirements.

[0028] In actual operation, the drive assembly includes a motor 2 and a push rod 8. The motor 2 is mounted on the drive end of the push rod 8. The drive end of the push rod 8 is rotatably connected to the crossbar 9 set on the frame 1, so that the push rod 8 can swing around the crossbar 9 as the center. The telescopic end of the push rod 8 is rotatably connected to the corresponding movable part. The push rod 8 receives the driving force from the motor 2 and drives the telescopic end to telescopic movement, thereby driving the movable part to move under the support of the crossbar 9, and playing the role of adjusting the contour of the support surface.

[0029] In actual operation, the noise reduction box 3 has a receiving cavity with an opening at the top. The noise reduction box 3 is placed on the motor 2 from bottom to top through the opening and is fixedly connected to the fixing part so that the motor 2 is completely enclosed. The periphery of the opening extends outward to form a flange 11, and the flange 11 is fitted and fixedly connected to the bottom surface of the fixing part (e.g., Figure 5 (As shown). The fixing part has a flat bottom surface. The noise reduction box 3 moves from bottom to top and is placed on the motor 2 through the cavity opening of the receiving cavity until the noise reduction box 3 abuts against the bottom surface of the fixing part through the flange 11 and is fixed by fasteners, so that the motor 2 is completely wrapped and hidden in the receiving cavity, effectively preventing the noise generated by the motor 2 from being transmitted outward.

[0030] In actual operation, a sound-absorbing gap is reserved between the inner wall of the receiving cavity and the outer wall of the motor 2. The size of the receiving cavity is larger than the size of the motor 2, which facilitates the placement of the noise reduction box 3 on the motor 2, preventing the motor 2 from bumping or scratching against the noise reduction box 3 and protecting the motor 2. It can also use the sound-absorbing gap to eliminate the noise generated by the operation of the motor 2. By guiding the noise to reflect back and forth in the sound-absorbing gap, energy is consumed, thereby eliminating the noise. At the same time, it ensures that the motor 2 and the noise reduction box 3 do not come into contact with each other, thereby preventing the vibration generated by the operation of the motor 2 from being transmitted outward through the noise reduction box 3.

[0031] In actual operation, a perforation 7 is provided on the side wall of the noise reduction box 3. The driving end of the push rod 8 is connected to the motor 2, and the telescopic end passes through the perforation 7 and is rotatably connected to the movable part. The telescopic end driven by the motor 2 drives the movable part to move through telescopic movement. The perforation 7 is a vertically elongated strip, providing space for the push rod 8 to swing vertically. Since the back support plate 15 or the thigh plate 14 can swing vertically, the telescopic end of the push rod 8 will also swing up and down accordingly. By setting the elongated perforation 7 to provide space for the vertical swing of the push rod 8, the situation where the movable part cannot swing normally due to the push rod 8 contacting the edge of the perforation 7 is prevented, ensuring that the contour of the support surface can be flexibly adjusted.

[0032] In actual operation, the frame 1 includes a crossbar 9 for connecting the drive end of the push rod 8, the motor 2 is installed at the drive end of the push rod 8, and the edge of the cavity is provided with a clearance notch 10 (e.g., Figure 4As shown, the crossbar 9 is embedded in the clearance notch 10, and the edge of the cavity is fitted and fixed to the bottom surface of the fixing part to eliminate the gap between the noise reduction box 3 and the fixing part. The bottom surface of the fixing part fits with the clearance notch 10 and tightly wraps the crossbar 9, effectively reducing the gap between the crossbar 9 and the clearance notch 10 and preventing noise from being transmitted outward through the gap. In addition, the drive end of the push rod 8 is connected to the crossbar 9, and the wrapping range of the noise reduction box 3 is expanded by wrapping the section of the crossbar 9 used to connect the push rod 8, thereby reducing the vibration and noise transmitted outward.
