Abstract
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 soundproof box. The soundproof box encloses the motor and some push rods, forming a soundproof gap that covers the surfaces of the motor and push rods. This effectively prolongs the duration of noise retention within the soundproof gap, thereby improving noise reduction and enhancing the user experience.
[0004] This utility model achieves its purpose through the following method: a bed frame with a soundproof 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 and a push rod. The frame body is provided with a soundproof box that completely encloses the motor and a portion of the push rod. A soundproof gap is reserved between the inner wall of the soundproof box and the outer wall of the motor. The noise generated by the motor is reflected back and forth within the soundproof gap and dissipated, thus limiting the outward transmission of noise. By using the soundproof box to enclose the motor and a portion of the push rod and forming a soundproof gap covering the surfaces of the motor and the push rod, the noise generated by the motor is reflected back and forth within the soundproof gap and dissipated, effectively extending the residence time of the noise within the soundproof gap, thereby improving the noise reduction effect and enhancing the user experience.
[0005] Preferably, the soundproof box includes a base with an internal receiving groove and a cover plate that closes to the opening of the receiving groove. The motor is embedded in the receiving groove and covered by the cover plate to block noise transmission. The base and cover plate are separate units, which facilitates independent processing and allows the motor to be embedded in the base and closed by the cover plate, making assembly convenient. Assembly also allows for a tight seal around the motor and the adjacent push rod section, preventing noise transmission through the joint between the base and cover plate and ensuring sound insulation.
[0006] 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 swing through the push rod. The fixed part is fixedly connected to the frame and provides support for the movable part, ensuring that the movable part can move along a preset path, effectively improving the movement accuracy of the movable part.
[0007] Preferably, the receiving groove is T-shaped, including a main cavity housing the motor and a secondary cavity housing the push rod. The main cavity and the secondary cavity are perpendicular to each other to reduce noise transmission from the main cavity to the secondary cavity. The main cavity is vertically positioned in the middle of the secondary cavity, so that the contour of the receiving cavity corresponds to the installation positions of the motor and the push rod, ensuring that the motor and the push rod can be installed in the main cavity and the secondary cavity respectively. The main cavity is used to house the motor, and the secondary cavity is used to enclose the section of the push rod adjacent to the motor. This ensures that the noise generated by the motor must pass through the sound insulation gaps in the main cavity and the secondary cavity before it can propagate outward. By extending the residence time of the noise in the receiving cavity, the energy dissipation effect is improved, thereby ensuring that the noise can dissipate within the sound insulation gaps.
[0008] Preferably, the end face of the secondary cavity is provided with a through hole, the drive end of the push rod is connected to the frame, and the telescopic end passes through the through hole and is connected to the movable part. The telescopic end is exposed through the through hole and connected to the corresponding movable part. The telescopic end controls the swing of the movable part through telescopic movement, thereby making the contour of the support component variable and providing comfortable support for the user.
[0009] 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.
[0010] Preferably, the frame includes a crossbar for mounting the drive end of the push rod. The motor is fixed to the drive end of the push rod and drives the telescopic end to extend and retract. The edge of the slot has a clearance notch for the crossbar to be embedded and concealed. The base covers the motor from bottom to top and is fixed to a cover plate fixed to the bottom surface of the fixing part, so that the crossbar avoids the soundproof box through the clearance notch. 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 slot avoids the crossbar through the clearance notch, which ensures that the soundproof box can be firmly connected to the fixing part, and also reduces outward noise by wrapping the crossbar with the clearance notch, ensuring that noise can be reflected and dissipated within the soundproof gap.
[0011] Preferably, the periphery of the slot is bent outward to form a flange, and the edge of the cover plate covers and is fixedly attached to the flange. The flange and the edge of the cover plate are fixedly attached to each other, which not only improves the reliability of the connection, but also effectively prevents noise from being transmitted outward, thus improving the sound insulation effect.
[0012] Preferably, both the base and the cover are made of stainless steel, which is convenient to process, has good sound insulation, and can effectively reduce raw material costs.
[0013] 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.
[0014] The beneficial effects of this utility model are as follows: by using a soundproof box to wrap the motor and a partial push rod and forming a soundproof gap covering the surface of the motor and the partial push rod, the noise generated by the motor will be reflected back and forth in the soundproof gap and dissipated, effectively prolonging the residence time of the noise in the soundproof gap, thereby improving the noise reduction effect and enhancing the user experience.

[0019] The essential features of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0020] like Figure 1 The bed frame shown includes a soundproof box 4, comprising a frame body 1, a support assembly mounted on the frame body 1, and a drive assembly for driving the support assembly. The drive assembly includes a motor 2 and a push rod 3. The frame body 1 is characterized by having a soundproof box 4 that completely encloses the motor 2 and a portion of the push rod 3. A soundproof gap is reserved between the inner wall of the soundproof box 4 and the outer wall of the motor 2. Noise generated by the motor 2 is reflected and dissipated within this gap, limiting its outward transmission. By using the soundproof box 4 to enclose the motor 2 and the portion of the push rod 3, forming a soundproof gap covering their surfaces, noise generated by the motor 2 is reflected and dissipated within this gap, effectively extending the noise's residence time and thus improving noise reduction and user experience.
[0021] In actual operation, the support assembly includes a fixed part that is fixedly connected to the frame 1 and a movable part that can move relative to the fixed part. The motor 2 drives the movable part to swing through the push rod 3. The fixed part consists of a lumbar support plate 12 and a hip support plate 13 that are placed front and rear respectively. The movable part includes a back support plate 14 that swings and connects to the front edge of the lumbar support plate 12 and a thigh plate 15 that swings and connects to the rear edge of the hip support plate 13. The drive assembly consists of two sets, which drive the back support plate 14 and the thigh plate 15 to swing independently respectively. The rear edge of the back support plate 14 is connected to the front edge of the lumbar support plate 12 via a pivot, allowing the back support plate 14 to swing around the front edge of the lumbar support plate 12. The front edge of the thigh plate 15 is connected to the rear edge of the hip support plate 13 via a pivot, allowing the hip support plate 13 to swing around the rear edge of the hip support plate 13. There are two sets of drive components, which are used to drive the back support plate 14 and the thigh plate 15 within a preset range of motion, ensuring that both can be driven by the corresponding drive components. This effectively improves the motion accuracy of the back support plate 14 and the thigh plate 15 and ensures that the contour of the support surface meets the user's differentiated usage requirements.
[0022] In actual operation, the drive assembly includes a motor 2 and a push rod 3. The motor 2 is mounted on the drive end of the push rod 3. The drive end of the push rod 3 is rotatably connected to the crossbar 8 set on the frame 1, so that the push rod 3 can swing around the crossbar 8 as the center. The telescopic end of the push rod 3 is rotatably connected to the corresponding movable part. The push rod 3 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 8, and playing the role of adjusting the contour of the support surface.
[0023] In actual operation, the soundproof box 4 includes a base 5 with an internal receiving groove 9 and a cover plate 6 that covers the opening of the receiving groove 9 (e.g., Figure 2 As shown in the diagram, the motor 2 is embedded in the receiving groove 9 and covered by the cover plate 6 to prevent noise from being transmitted outward. During installation, the cover plate 6 is fixed to the bottom surface of the fixing part (e.g., Figure 3 As shown, the base 5 wraps around the motor 2 from bottom to top and is fixedly connected to the cover plate 6, so that the base 5 is fixedly connected to the bottom surface of the fixing part through the cover plate 6.
[0024] In actual operation, the frame 1 includes a crossbar 8 for mounting the drive end of the push rod 3. The motor 2 is fixed to the drive end of the push rod 3 and drives the telescopic end to extend and retract. The edge of the slot is provided with a clearance notch 10 for the crossbar 8 to be embedded and hidden. The base 5 covers the motor 2 from bottom to top and is fixed to the cover plate 6 fixed to the bottom surface of the fixed part, so that the crossbar 8 avoids the sound insulation box 4 through the clearance notch 10. When the base 5 is fixed to the cover, the clearance notch 10 and the cover plate 6 cooperate to wrap the crossbar 8, thereby improving the sound insulation effect by eliminating the gap between the clearance notch 10 and the crossbar 8.
[0025] In actual operation, the periphery of the slot is bent outward to form a flange 11, and the edge of the cover plate 6 covers the flange 11 and is fixedly attached. The flange 11 is continuously arranged along the periphery of the slot to ensure that each section of the periphery of the slot can be tightly attached to the cover plate 6, which not only improves the reliability of the connection, but also improves the sound insulation effect by increasing the width of the contact area.
[0026] In actual operation, the receiving groove 9 is T-shaped, including a main cavity housing the motor 2 and a secondary cavity housing the push rod 3. The main cavity and the secondary cavity are arranged perpendicularly to each other to reduce noise transmission from the main cavity to the secondary cavity. The receiving groove 9 is T-shaped, and the motor 2 and push rod 3, after being fixed together, also form a T-shape. By setting the same structural contour, it is easier for the motor 2 and push rod 3 to be inserted into the receiving groove 9, thereby improving assembly convenience. The base 5 and the cover plate 6 are stacked and assembled to form a main cavity for accommodating the motor 2 and a secondary cavity for accommodating a partial section of the push rod 3. The section of the push rod 3 adjacent to the motor 2 is enclosed by the secondary cavity, which uses the secondary cavity to perform secondary energy dissipation and noise reduction on noise from the main cavity, thereby improving the sound insulation effect.
[0027] In actual operation, the end face of the secondary cavity is provided with a through hole 7. The driving end of the push rod 3 is connected to the frame 1, and the telescopic end passes through the through hole 7 and is connected to the movable part. The soundproof box 4 encloses the section of the motor 2, the section of the push rod 3 adjacent to the motor 2, and the section of the crossbar 8 adjacent to the push rod 3. The driving end of the push rod 3 is located inside the soundproof box 4 and is rotatably connected to the crossbar 8. The telescopic end of the push rod 3 is exposed through the through hole 7 and connected to the corresponding movable part. The through hole 7 is a vertically elongated strip, providing space for the push rod 3 to swing vertically, thereby ensuring that the push rod 3 will collide and lock with the through hole 7 when it is linked with the movable part, and ensuring that the movable part can be freely adjusted within a preset range under the drive of the push rod 3.
[0028] In practice, the base 5 and the cover plate 6 are made of stainless steel, which is convenient to process, has a good sound insulation effect, and can effectively reduce the cost of raw materials.
