[0002] In order to improve the riding experience and comfort, commercial vehicles are currently equipped with flip tables for rear passengers. These tables are mostly installed with hinges, but ordinary hinges are set with two hinged hinge pieces and have no damping settings. Therefore, it is easy to cause abnormal noise when opening or closing, and the stability will also be affected by the vibration of the car body.

[0003] Therefore, a damping hinge with simple structure and convenient assembly is in urgent need of research. Utility Model Content

[0004] In view of this, the technical problem to be solved by the present invention is to provide a damping hinge for a vehicle interior table top, so as to avoid the problem that the conventional hinge structure is simple and lacks damping.

[0005] In order to solve the above technical problems, the utility model discloses a damping hinge for a vehicle interior table top, comprising:

[0006] The connecting support is U-shaped and has shaft holes at both ends. The shaft hole has a circular hole portion and a T-shaped hole portion located at the bottom of the circular hole portion.

[0007] A jacket is embedded in the shaft hole, and the jacket comprises a limit block portion accommodated in the T-shaped hole portion and a clamping block portion located in the circular hole portion;

[0008] A hinge shaft is inserted into the jacket, the hinge shaft having shaft handles exposed at both ends, and anti-slip grooves are provided on opposite sides of the shaft handles; and

[0009] A hinge piece that is sleeved on the shaft handle.

[0010] According to one embodiment of the present invention, the clamping block clamps the hinge shaft, and both ends are not closed.

[0011] According to one embodiment of the present invention, the shaft handle is drum-shaped and has an interference fit with the shaft hole of the hinge piece.

[0012] According to one embodiment of the present invention, the outer side of the hinge piece has two opposing mounting bolt holes.

[0013] According to one embodiment of the present invention, triangular limit blocks are provided on the outer sides of both ends of the connecting support for stopping against the hinge piece.

[0014] Compared with the prior art, the present invention can achieve the following technical effects:

[0015] The sleeve is installed through the shaft hole that matches the round hole and the T-shaped hole, and then the hinge shaft is installed to provide a damping effect during rotation and stable assembly; anti-slip grooves are set at the end of the hinge shaft to enhance the stability of the hinge piece in bearing rotation.

[0016] Of course, any product implementing the present utility model does not necessarily need to achieve all of the above-mentioned technical effects at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following will describe the implementation of the present invention in detail with reference to the accompanying drawings and examples, so that the implementation process of how the present invention applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0024] Please refer to Figures 1 to 3 , Figure 1 This is a schematic diagram of a damping hinge for a vehicle interior tabletop according to an embodiment of the utility model; Figure 2 This is a schematic diagram of a connecting support according to an embodiment of the present utility model; Figure 3 This is a schematic diagram of the installation of the hinge shaft and the jacket according to an embodiment of the present invention.

[0025] As shown in the figure, a damping hinge for a table top in a vehicle includes: a connecting support 10, which is U-shaped and has an axial hole 20 located at both ends, the axial hole 20 has a circular hole portion and a T-shaped hole portion located at the bottom of the circular hole portion; a sleeve 30 embedded in the axial hole 20, the sleeve 30 has a limit block portion accommodated in the T-shaped hole portion and a clamping block portion located in the circular hole portion; a hinge shaft 40 passed through the sleeve 30, the hinge shaft 40 has a shaft handle exposed at both ends, and anti-slip grooves 41 are provided on opposite sides of the shaft handle; and a hinge piece 50 sleeved on the shaft handle.

[0026] In one embodiment of the present invention, the connecting support 10 is in the shape of a U-shaped block, and the ends of the protruding parts at both ends are provided with a through-hole 20 for installing the hinge shaft 40. At the same time, the shaft hole 20 is not a circular hole design, but is composed of a circular hole portion and a T-shaped hole portion. In this way, the stability of the sleeve 30 can be ensured, radial sliding is not generated, and the sleeve 30 is locked. The sleeve 30 is used to clamp the hinge shaft 40, avoiding contact between the hinge shaft 40 and the shaft hole 20, and improving the friction between the two. The sleeve 30 can be set to a high-damping material, such as rubber silicone, etc. The end of the hinge shaft 40 is thickened to form a shaft handle, and an anti-slip pattern 41 is provided at the outer end of the shaft handle to improve the stability of the installation of the hinge piece 50.

[0027] Preferably, the clamping block clamps the hinge shaft 40, and the two ends are not closed, that is, the clamping block is a non-closed ring, which can clamp the hinge shaft 40, improve assembly toughness, facilitate replacement, and ensure stable installation.

[0028] The shaft of the hinge shaft 40 is drum-shaped, ie non-circular, to avoid radial rotation. Its arc surface is provided with anti-slip grooves 41 and is interference-fitted with the shaft hole of the hinge piece 50 .

[0029] In addition, the outer side of the hinge piece 50 has two opposite mounting bolt holes for fixing the table top, which plays a connecting role.

[0030] It is worth mentioning that triangular limit blocks 60 are provided on the outer sides of both ends of the connecting support 10. The triangular limit blocks 60 are used to stop the hinge piece 50 and provide a dead point for the rotation of the table top, so that the table top can lie flat for placing objects.

[0031] To sum up, the utility model installs the sleeve through the shaft hole that matches the round hole and the T-shaped hole, and then installs the hinge shaft to provide a damping effect during rotation and at the same time ensure stable assembly; anti-slip grooves are set at the end of the hinge shaft to enhance the stability of the hinge piece in bearing rotation.

[0032] The above description shows and describes several preferred embodiments of the present invention. However, as previously mentioned, it should be understood that the present invention is not limited to the form disclosed herein and should not be construed as excluding other embodiments. Instead, the present invention can be used in various other combinations, modifications, and environments and can be modified within the scope of the present invention as taught herein or through the techniques or knowledge in the relevant field. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention are intended to be protected by the claims appended hereto.
