Technical Field

[0001] The utility model relates to the technical field of vehicle accessories, in particular to a hidden damping hinge and a table board. Background Art

[0002] With the improvement of people's living standards and the increasing requirements for the utilization efficiency of the interior space of vehicles, more and more vehicle owners hope to enjoy more comfortable and convenient services during their journeys. Especially during long-distance driving or family outings, a small workbench or dining table that is stable, reliable, easy to operate and does not occupy too much space is particularly important.

[0003] However, there are some deficiencies in the design and use of existing folding table boards for vehicle seats, especially defects related to hinge joints:

[0004] The distance between the two table boards is large when opened: The design of traditional hinges often results in a large gap between the two table boards when the table board is fully unfolded. This not only affects the overall flatness of the tabletop, but also makes small objects easily fall into the gap, bringing inconvenience to users.

[0005] The hinge joint is exposed and not beautiful: Since the hinge joint is usually located at the connection of the table board and is exposed, it destroys the overall simplicity and beauty of the table board. Especially in modern vehicles that pursue refined interiors, this design obviously does not meet the aesthetic requirements of the high-end market.

[0006] Based on the above analysis, it can be seen that developing a new type of hidden damping hinge that is both safe and practical and its supporting folding table board has become one of the technical problems that need to be solved urgently. Such improvements can not only enhance the safety and beauty of the table board, but also improve its functionality and user experience. Summary of the Utility Model

[0007] The utility model aims to provide a hidden damping hinge and its supporting table board, and by optimizing the internal structure and installation method of the hinge, a more stable and safe operation experience can be achieved, and the service life and appearance beauty of the product can be improved.

[0008] The utility model provides a hidden damping hinge, which specifically includes two hinge leaves, two rotating shafts, a coupling piece and a damping piece. The coupling piece is bent so that both ends are on the same side. The damping piece is sleeved on the rotating shaft and installed in the through groove at the end of the coupling piece, and both ends of the rotating shaft are fixedly connected to the hinge leaves.

[0009] Furthermore, there are several damping pieces, and the damping size is adjusted as needed. The several damping pieces are installed side by side on the rotating shaft and are clamped with the coupling piece. A cover plate is also provided at the end of the coupling piece to block the through groove to prevent dust and liquid from entering and affecting the damping size.

[0010] Preferably, the coupling member is U-shaped, with protrusions designed on both sides. A buffer member is further provided between the protrusions and the hinge leaf, and the buffer member is installed on the hinge leaf to improve the tightness between the coupling member and the hinge leaf.

[0011] Furthermore, a number of mounting holes are provided on the hinge leaf for fixing to the connecting object by screws. A convex block is also provided on the side of the hinge leaf in contact with the connecting object, and the hinge leaf is inserted into the connecting object through the convex block to further enhance the overall tightness.

[0012] Preferably, an anti-vibration convex block is also designed at the end of the coupling member, and the anti-vibration convex block is in sliding contact with the connecting object. When the connecting object rotates, the anti-vibration convex block always abuts against the connecting object to prevent the connecting object from loosening and shifting.

[0013] The present utility model also discloses a table board with a hidden damping hinge, which includes the hinge described above, and further includes a first table board and a second table board. The hinge leaf is fixed on the same side of the first table board and the second table board through fasteners, and the top surfaces of the first table board and the second table board cover both ends of the coupling member to achieve the hiding of the damping hinge.

[0014] Furthermore, both the first table board and the second table board include a board frame, a middle frame, an upper decorative board, and a lower decorative board. The upper decorative board and the lower decorative board respectively wrap the middle frame, and the upper decorative board and the lower decorative board are respectively fixed above and below the board frame.

[0015] Preferably, a mirror is further provided at the bottom of the second table board. The mirror is rotatably installed on the second table board through a shaft rod, and magnets are provided inside the second table board and inside the mirror. When the mirror is stored, the mirror is adsorbed and fixed to the bottom of the second table board.

[0016] Preferably, the first table board and the second table board are designed with an arc surface near the anti-vibration convex block, so that when the first table board and the second table board are folded, the arc surfaces of the first table board and the second table board are inserted into the clamping opening of the U-shaped coupling member. Notches are provided on the contact surfaces of the first table board and the second table board with the anti-vibration convex block. When the first table board and the second table board rotate, the anti-vibration convex block continuously abuts against the notches to make the whole more stable.

[0017] Compared with the prior art, the hidden damping hinge provided by the present utility model has significant technical advantages. First of all, the design of this hinge enables two connecting components to be installed together very tightly, and the hinge is hardly visible from the front, thus significantly improving the overall aesthetics. In addition, this hidden design reduces the accumulation of dust and dirt, facilitating daily cleaning and maintenance.

[0018] By adding a buffer between the coupling piece and the hinge and setting an anti-vibration bump between the coupling piece and the connecting object, the overall structural strength and stability of the hinge are greatly enhanced. These improvement measures effectively reduce the impact on the hinge caused by frequent use and vibration, reduce the risk of wear and loosening, and thus extend the service life of the product.

[0019] The present utility model also provides a tabletop with a hidden damping hinge. The tabletop shows higher stability and quiet performance during the opening and closing process.
