Description

Technical Field

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

[0002] The existing bed frame includes a frame body, a support assembly mounted on the frame body, and a drive assembly that drives the support assembly. The drive assembly includes a motor and a push rod. The push rod extends and retracts under the drive of the motor, thereby driving the movable part on the support assembly to move. 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 different scenarios. Because the motor generates noise due to vibration and friction during high-speed rotation, it can affect the user's sleep and impact the user experience. Therefore, a noise-reducing shell is fitted onto the motor, with perforations for the push rod to extend outwards. However, the noise-reducing shell is relatively large, occupying significant space within the frame and increasing the difficulty of assembling adjacent components. Furthermore, the noise generated by the motor can be transmitted outwards through the perforations, resulting in poor noise reduction and affecting the user experience. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a bed frame with a small-volume noise-reducing shell. The small-volume noise-reducing shell has an internal cavity contour that matches the contour of the drive unit. This not only prevents noise from being transmitted outward by enclosing the drive unit, but also exposes part of the drive components, ensuring that noise is confined within the noise-reducing shell. Furthermore, by reducing the volume of the noise-reducing shell, the space occupied is reduced, effectively improving the user experience.

[0004] This utility model is achieved through the following method: a bed frame with a small-volume noise-reducing shell, including a frame body, a support component mounted on the frame body, and a drive component that drives the support component. The drive component includes a drive part and a noise-reducing shell that encloses the drive part. The noise-reducing shell has a receiving cavity that matches the contour of the drive part. A noise-reducing gap is formed between the inner wall of the receiving cavity and the outer wall of the drive part. The volume of the noise-reducing shell is reduced by limiting the thickness of the noise-reducing gap. By setting a small-volume noise-reducing shell, and ensuring that the contour of the receiving cavity matches the contour of the drive part, the noise-reducing gap formed by enclosing the drive part prevents noise from being transmitted outward, effectively eliminating the noise generated by the motor operation. Furthermore, by enclosing the drive part, the drive component is partially exposed, eliminating the need for perforations and ensuring that all noise is confined within the noise-reducing shell. This also effectively reduces the volume of the noise-reducing shell, thereby reducing the space occupied within the frame, facilitating the assembly of adjacent components, and effectively improving the user experience.

[0005] Preferably, the thickness of the noise reduction gap is A, where A≤5mm. This not only eliminates noise by setting the noise reduction gap, where noise is reflected back and forth and consumes energy, thus eliminating noise, but also reduces the volume of the noise reduction shell by limiting the thickness of the noise reduction gap, thereby effectively utilizing the space inside the frame.

[0006] Preferably, the noise-reducing shell includes an L-shaped upper shell and a lower shell, which are vertically stacked and enclose a cavity to enclose the drive unit. The noise-reducing shell is a split structure, with the upper and lower shells formed independently to facilitate assembly, improve assembly efficiency, enhance the sealing between the upper and lower shells, and improve sound insulation.

[0007] Preferably, the supporting assembly includes a fixed part that is fixed to the frame and a movable part that moves relative to the fixed part. The driving part is L-shaped and includes a motor and a push rod perpendicular to the motor axis. The push rod, driven by the motor, drives the movable part through its telescopic end. The receiving cavity is L-shaped and is used to enclose the motor and the push rod, ensuring that the motor is completely enclosed by the receiving cavity, that the driving end of the push rod connected to the motor is also enclosed by the receiving cavity, and that the telescopic end of the push rod is exposed in the receiving cavity. This facilitates the movement of the movable part through telescopic movement, eliminating the need to provide movement space for the push rod within the receiving cavity. The sound insulation effect is improved by reducing the gap between the receiving cavity and the push rod.

[0008] Preferably, the motor is cylindrical, and the upper and lower housings are respectively provided with an upper main groove and a lower main groove with a semi-circular cross-sectional profile. The upper and lower main grooves face each other and enclose the motor to form an annular noise reduction gap. The cross-section of the cavity of both the upper and lower main grooves is semi-circular, so that the upper and lower main grooves can be stacked to form a cylindrical main cavity, which not only encloses the motor, but also achieves a noise reduction gap between the inner wall of the main cavity and the outer wall of the motor by setting reasonable dimensional differences, thereby reducing the noise generated by the motor.

[0009] Preferably, the upper housing has an upper sub-groove, and the lower housing has a lower sub-plate. The lower sub-plate covers the upper sub-groove and encloses the push rod. The upper sub-groove and the lower sub-plate are stacked to form a sub-cavity for enclosing the push rod, effectively extending the distance that noise travels from the main cavity through the sub-cavity to the outside, thereby reducing the noise propagating outward.

[0010] Preferably, the upper main slot and the upper auxiliary slot are interconnected, and the axis of the upper main slot and the axis of the upper auxiliary slot are perpendicular to each other, ensuring that the upper main slot and the upper auxiliary slot can respectively enclose the motor and the push rod, ensuring that the contour of the upper housing matches the contour of the drive unit, thereby effectively reducing the volume of the noise reduction housing and facilitating assembly.

[0011] Preferably, both ends of the upper sub-slot are exposed. The drive end of the push rod is exposed at one end of the upper sub-slot and rotatably connected to the frame, while the telescopic end is exposed at the other end of the upper sub-slot and rotatably connected to the movable part. The exposed ends of the upper sub-slot facilitate the exposure of the drive and telescopic ends of the push rod, ensuring that the push rod can be connected to the frame via the drive end and that the telescopic end is exposed and connected to the movable part. Since the noise-reducing shell only covers the middle of the push rod and can be linked with it, there is no need to provide perforations or movement space for relative movement of the push rod on the noise-reducing shell. This reduces the distance between the push rod and the noise-reducing shell, thereby improving the sound insulation effect.

[0012] 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.

[0013] Preferably, the bottom periphery of the upper housing and the top periphery of the lower housing are each provided with connecting lugs with mounting holes. The upper and lower housings are stacked and mounted, and are fixedly locked together by fasteners passing through the corresponding mounting holes. The stacking and fixing of the upper and lower housings with fasteners passing through the corresponding connecting lugs prevents noise transmission by eliminating gaps between the upper and lower housings.

[0014] The beneficial effects of this utility model are as follows: The noise reduction shell is designed with a small volume, and the contour of the cavity inside the noise reduction shell matches the contour of the drive unit. It not only forms a noise reduction gap to prevent noise from being transmitted outward by wrapping the drive unit, effectively eliminating the noise generated by the motor operation, but also exposes part of the drive component by wrapping the drive unit, eliminating the need for perforations and ensuring that the noise is confined within the noise reduction shell. Furthermore, it effectively reduces the volume of the noise reduction shell to reduce the space occupied in the frame, facilitates the assembly of adjacent components, and effectively improves the user experience.

[0020] The essential features of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] like Figure 1 The bed frame shown includes a small-volume noise-reducing shell, comprising 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 drive section and a noise-reducing shell 2 that encloses the drive section. The noise-reducing shell 2 has a receiving cavity that matches the contour of the drive section. A noise-reducing gap is formed between the inner wall of the receiving cavity and the outer wall of the drive section. The volume of the noise-reducing shell 2 is reduced by limiting the thickness of the noise-reducing gap. The small-volume noise-reducing shell 2, with its inner cavity contour matching the contour of the drive section, effectively eliminates noise generated by the motor 5 by enclosing the drive section and forming a noise-reducing gap to prevent noise transmission. It also partially exposes the drive assembly, eliminating the need for large perforations and ensuring that noise is confined within the noise-reducing shell 2. Furthermore, the reduced volume of the noise-reducing shell 2 minimizes the space occupied within the frame body 1, facilitating the assembly of adjacent components and improving the user experience.

[0022] In actual operation, the supporting component includes a fixed part that is fixed to the frame 1 and a movable part that moves relative to the fixed part. The driving part is L-shaped and includes a motor 5 and a push rod 6 that is perpendicular to the axis of the motor 5. The push rod 6 driven by the motor 5 drives the movable part to move through the telescopic end.

[0023] In actual operation, the noise reduction shell 2 includes an L-shaped upper shell 3 and a lower shell 4, which are vertically stacked and enclose a cavity to enclose the drive unit. The upper shell 3 includes an upper main groove 7 and an upper secondary groove 9 (e.g., ...). Figure 2 As shown), the lower housing 4 includes a lower main groove 8 and a lower auxiliary plate 10. The upper main groove 7 and the upper auxiliary groove 9 are interconnected. The axis of the upper main groove 7 and the axis of the upper auxiliary groove 9 are perpendicular to each other. The motor 5 is mounted on the driving end of the push rod 6, and the axis of the motor 5 is perpendicular to the axis of the push rod 6. During installation, the upper housing 3 and the lower housing 4 close together and enclose the motor 5 and the section adjacent to the push rod 6 and the motor 5. The groove openings of the upper main groove 7 and the lower main groove 8 are correspondingly arranged and enclose the motor 5 by closing together. The groove opening of the upper auxiliary groove 9 and the lower auxiliary plate 10 close together and enclose the section adjacent to the push rod 6 and the motor 5 (e.g., Figure 3As shown in the figure, after installation, the connecting ears 15 on the upper housing 3 and the lower housing 4 are aligned with each other and fixed together by fasteners so that the bottom surface of the upper housing 3 and the top surface of the lower housing 4 fit tightly together, effectively preventing noise from being transmitted outward through the gap between the upper housing 3 and the lower housing 4.

[0024] In actual operation, the motor 5 is cylindrical. The upper housing 3 and the lower housing 4 are respectively provided with an upper main groove 7 and a lower main groove 8 with a semi-circular cross-sectional profile. The upper main groove 7 and the lower main groove 8 face each other and close together to wrap around the motor 5, forming an annular noise reduction gap. The upper main groove 7 and the lower main groove 8 close together to form a main cavity for wrapping the motor 5. The main cavity is cylindrical, and the diameter of the main cavity is larger than the diameter of the motor 5. This allows the main cavity to form a noise reduction gap surrounding the motor 5 after wrapping around it. The noise reduction gap can not only reflect and dissipate the noise generated by the motor 5, thereby eliminating the noise, but also effectively block the vibration generated by the operation of the motor 5 from being transmitted outward, thereby preventing noise from adjacent components due to vibration and impact.

[0025] In actual operation, the thickness of the noise reduction gap is A, where A≤5mm. This not only serves to reduce noise, but also reduces the volume of the noise reduction shell 2 by limiting the upper limit of parameter A, thereby improving assembly convenience.

[0026] In actual operation, the upper housing 3 is provided with an upper auxiliary groove 9, and the lower housing 4 is provided with a lower auxiliary plate 10. The lower auxiliary plate 10 covers the upper auxiliary groove 9 and encloses the push rod 6. The upper auxiliary groove 9 and the lower auxiliary plate 10 are stacked and enclosed to form a partial section enclosing the push rod 6.

[0027] In actual operation, the two ends of the upper sub-slot 9 are exposed. The drive end of the push rod 6 is exposed at one end of the upper sub-slot 9 and rotatably connected to the frame 1, while the telescopic end is exposed at the other end of the upper sub-slot 9 and rotatably connected to the movable part. The lower sub-plate 10 covers the downward-facing slot of the upper sub-slot 9 and forms a sub-cavity. The two ends of the sub-cavity are exposed, facilitating the exposure of both ends of the push rod 6. The drive end of the push rod 6 is rotatably connected to the frame 1, serving to fix and guide the swing of the push rod 6. The telescopic end of the push rod 6 is rotatably connected to the movable part, and the telescopic end drives the movable part to swing through telescopic movement. Since the push rod 6 is partially encased by the noise-reducing shell 2, the noise-reducing shell 2 can move synchronously with the push rod 6 without providing interactive space for the push rod 6. This effectively reduces the volume of the noise-reducing shell 2 and improves the ease of movement, preventing the noise-reducing shell 2 from colliding with adjacent components when moving with the push rod 6.

[0028] In actual operation, the bottom periphery of the upper housing 3 and the top periphery of the lower housing 4 are provided with connecting ears 15 with mounting holes. The upper housing 3 and the lower housing 4 are stacked and installed, and are fixed and locked together by fasteners passing through the corresponding mounting holes. The bottom periphery of the upper housing 3 is provided with multiple connecting ears 15, and the top periphery of the lower housing 4 is also provided with multiple connecting ears 15. After the upper housing 3 and the lower housing 4 are stacked, the corresponding connecting ears 15 are precisely stacked and fixed together by fasteners to ensure that the upper housing 3 and the lower housing 4 are firmly connected.

[0029] 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 5 drives the movable part to move through the push rod 6. The fixed part consists of a lumbar support plate 11 and a hip support plate 12 placed at the front and back (e.g., ...). Figure 4 As shown, the movable part includes a back support plate 13 that is sway-connected to the front edge of the lumbar support plate 11 and a thigh plate 14 that is sway-connected to the rear edge of the hip support plate 12. Two sets of drive components are provided, each driving the back support plate 13 and thigh plate 14 to swing independently. The rear edge of the back support plate 13 is connected to the front edge of the lumbar support plate 11 via a pivot, allowing the back support plate 13 to swing around the front edge of the lumbar support plate 11. The front edge of the thigh plate 14 is connected to the rear edge of the hip support plate 12 via a pivot, allowing the hip support plate 12 to swing around its rear edge. Two sets of drive components are provided, each driving the back support plate 13 and thigh plate 14 within a preset range of motion. This ensures that both can be driven by their respective drive components, effectively improving the movement accuracy of the back support plate 13 and thigh plate 14 and ensuring that the support surface contours meet the diverse usage requirements of users.
