Description

Technical Field

[0001] This utility model relates to the field of panel flipping technology, and in particular to a rounded inner panel flipping structure. Background Technology

[0002] Currently, most flip panels on the market use a right-angle design combined with traditional hinges to achieve the flipping function. While this technology is simple in structure, it has several drawbacks: First, the right-angled edges are easily chipped, damaged, or even scratched during frequent opening and closing, resulting in poor safety and durability. Second, the right-angle design appears abrupt and rigid in modern minimalist products, lacking aesthetic appeal and failing to meet consumers' aesthetic demands for rounded and softer appearances. Furthermore, the fixed pivot point of traditional hinges causes the right-angled portion of the panel to interfere with the movement of the cabinet or other components during flipping, requiring a larger operating space and limiting design flexibility.

[0003] To address the aforementioned issues, several flipping solutions employing sliding rails or complex linkage mechanisms have emerged. While these solutions mitigate interference to some extent, they introduce new drawbacks: exceptionally complex structures, numerous components, high manufacturing costs, and relatively high failure rates. Furthermore, these mechanisms are often designed for right-angled panels, making them unsuitable for the smooth flipping requirements of rounded-corner panels. For rounded-corner inner panels, existing technologies have yet to provide an effective and cost-efficient solution for achieving a perfect upright position on the side of the enclosure when open, while maintaining a smooth, consistent rounded transition with the surrounding contours when closed.

Example

[0028] Reference Figures 1 to 7 This embodiment provides a rounded inner panel flipping structure that can achieve a smooth flipping effect for the inner panel 6, which includes a housing assembly, a flipping assembly, and a lubrication assembly.

[0029] Specifically, the enclosure assembly includes an enclosure 1 and an inner panel 6 disposed inside the enclosure 1. The top of the enclosure 1 is provided with a cover 8. A stainless steel hinge 12 is provided on one inner wall of the cover 8. The other side of the stainless steel hinge 12 is attached to the inner wall of the enclosure 1. A cup-head screw 13 is provided between the stainless steel hinge 12 and the enclosure 1. A silicone pad 2 is provided on the top surface of the enclosure 1. A connecting bolt 9 that is threadedly connected to the enclosure 1 is provided on the edge of the cover 8. When the cover 8 is closed, the silicone pad 2 provides a sealing buffer, and the connecting bolt 9 securely locks it in place, ensuring a stable and reliable internal environment for the enclosure 1.

[0030] The flip assembly includes a fixing screw 3 on the inner wall of the housing 1, a slider 5 on the other side of the fixing screw 3, and a press-fit stud 16 on the outer wall of the inner panel 6. The top surface of the slider 5 has positioning grooves 17 on both sides. The inner panel 6 fits against the slider 5 and the press-fit stud 16 is located inside the positioning groove 17. The inner panel 6 has a handle cover 7 on the side away from the torque damping hinge 4. The end corner of the inner panel 6 is provided with a hand-tightening bolt 15 that is threaded to the housing 1. The end of the press-fit stud 16 is provided with a fastening nut 10. The fixing screw 3 is provided between the torque damping hinge 4 and the housing 1. The inner panel 6 slides along the positioning groove 17 through the press-fit stud 16 and the sleeve 11 to complete the relative movement of the inner panel 6. The inner panel 6 achieves smooth flipping relative to the housing 1 through the torque damping hinge 4, so that the inner panel 6 can stand perfectly upright on the side of the housing 1 after opening and flipping, and can maintain a smooth and consistent rounded transition with the surrounding contour when closed.

[0031] The lubrication assembly includes a sleeve 11 disposed on the outer surface of the press-fit stud 16. A confluence groove 22 is formed on the inner wall of the upper end of the sleeve 11, and an annular groove 28 is formed on the inner wall of the lower end of the sleeve 11. A guide groove 21 is formed between the annular groove 28 and the confluence groove 22. Multiple sets of guide grooves 21 are arranged in a circular array. An oil cavity 27 is formed inside the inner wall of the sleeve 11. An oil outlet hole 14 connected to the oil cavity 27 is formed on the inner wall of the annular groove 28. An oil injection hole 23 connected to the oil cavity 27 is formed on the top surface of the sleeve 11.

[0032] Furthermore, a storage groove 25 is provided on the upper outer surface of the sleeve 11, and a vent hole 26 communicating with the oil cavity 27 is provided in the bottom of the storage groove 25. A pressure plate 19 is slidably arranged inside the storage groove 25, and the bottom surface of the pressure plate 19 covers the opening of the vent hole 26. A sealing bolt 24 is threaded on the top opening of the oil injection hole 23. Guide platforms 18 are provided on both sides of the slider 5 located in the positioning groove 17. The top surface of the guide platform 18 is an inclined surface. The outer edge of the pressure plate 19 is located above the top surface of the guide platform 18. A spring plate 20 is provided between the top surface of the pressure plate 19 and the inner top of the storage groove 25.

[0033] In use, the operator flips the inner panel 6 by holding the bottom cover 7. The inner panel 6 slides along the positioning groove 17 through the rivet stud 16 and the sleeve 11, completing the relative movement of the inner panel 6. The inner panel 6 achieves smooth flipping relative to the box body 1 through the torque damping hinge 4, so that the inner panel 6 can stand perfectly upright on the side of the box body 1 after opening and flipping, and can maintain a smooth and consistent rounded transition with the surrounding contour when closed. The sleeve 11 converts sliding friction into rolling friction, which significantly reduces frictional resistance and makes the movement of the inner panel 6 relative to the slider 5 smoother and more stable. The torque damping hinge 4 connects the inner panel 6 and the box body 1, which plays a role in preventing it from falling. At the same time, the torque damping hinge 4 provides damping and buffering to avoid falling too fast or excessive impact. When the box cover 8 is closed, it achieves sealing and buffering through the silicone pad 2 and is firmly locked by the connecting bolt 9 to ensure that the internal environment of the box body 1 is stable and reliable. When the sleeve 11 slides along the positioning groove 17, the pressure plate 19 moves accordingly. The outer edge of the pressure plate 19 slides along the guide table 18. Since the top surface of the guide table 18 is an inclined surface, the pressure plate 19 is gradually lifted during the movement. The pressure plate 19 no longer covers the vent hole 26. The oil cavity 27 is connected to the outside through the vent hole 26. The lubricating oil inside the oil cavity 27 flows out through the oil outlet hole 14 under the action of gravity. The lubricating oil flowing out of the oil outlet hole 14 is collected through the ring groove 28 and diffused in the circumferential direction. The diversion groove 21 draws in the lubricating oil in the ring groove 28 under the action of capillary action. The confluence groove 22 at the end of the diversion groove 21 collects the lubricating oil again and disperses it to the diversion groove 21, so that the lubricating oil diffuses to the inner wall surface of the sleeve 11 and does not overflow. The lubricating oil forms an oil film between the inner wall surface of the sleeve 11 and the outer wall surface of the press-fit stud 16, which significantly reduces frictional resistance, reduces wear and abnormal noise. The inner panel 6 moves more smoothly and stably relative to the slider 5. When the inner panel 6 is closed, the sleeve 11 drives the pressure plate 19 to move. The pressure plate 19 is reset and no longer lifted by the guide table 18. Under the push of the spring plate 20, the pressure plate 19 covers the vent hole 26. The vent hole 26 is closed so that the lubricating oil inside the oil chamber 27 will not flow out with the oil outlet 14 under the action of atmospheric pressure, thus reducing the loss of lubricating oil. The inner panel 6 performs lubrication once every time it is opened and closed.

[0034] In summary, the problem of the inner panel 6 not flipping smoothly is solved by the cooperation of the housing assembly, the flipping assembly and the lubrication assembly. The automatic lubrication of the lubrication assembly ensures that each operation is accompanied by effective lubrication, which extends the service life of the mechanism, reduces the maintenance frequency, and the structure can remain stable when opened and transition naturally with the housing 1 when closed, with a simple and beautiful appearance.

[0035] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
