Detailed Description

The essential features and advantages of the utility model will be further explained below with reference to examples, but the utility model is not limited to the examples listed.

As shown in fig. 1 to 7, the vehicle door hinge of the present embodiment includes a first fixing block 1, a second fixing block 2, a first rotating arm 3 and a second rotating arm 4, where the first fixing block 1 and the second fixing block 2 are respectively connected to a vehicle body and a vehicle door. The first rotating arm 3 is rotatably connected with the first fixed block 1 through a first auxiliary shaft 10, and the second rotating arm 4 is rotatably connected with the second fixed block 2 through a second auxiliary shaft 20. The first rotating arm 3 and the second rotating arm 4 are rotatably connected through a main shaft 30, the first rotating arm 3 is provided with a first convex part 31, and the first convex part 31 is clamped in the first sliding groove 11 of the first fixing block 1. The second rotating arm 4 has a second protrusion 41, and the second protrusion 41 is engaged with the second sliding slot 21 of the second fixing block 2. In the above technical solution, when the vehicle door is opened, the vehicle door drives the second fixed block 2 to rotate around the main shaft 30, and meanwhile, the first and second convex portions of the first rotating arm 3 and the second rotating arm 4 move in the first sliding groove and the second sliding groove. Through setting up first, second spout, can disperse the atress and bear the weight of the point to can make the door hinge can bear bigger weight.

In this embodiment, the first fixing block 1 and the second fixing block 2 are both provided with fixing holes 22, and screws are disposed in the fixing holes 22, so that the first fixing block and the second fixing block can be fixed on the vehicle body and the vehicle door through the screws. The first auxiliary shaft 10, the second auxiliary shaft 20 and the main shaft 30 are shaft members with the same structure. The shaft element comprises a shaft body 101 and a sealing ring 102, the sealing ring 102 is sleeved on the shaft body 101, and the sealing ring can seal the shaft hole to prevent lubricating oil from leaking. The metal layer 103 is arranged on the outer wall of the shaft body 101, so that abrasion between the shaft body 101 and parts can be reduced, and the service life is prolonged. The shaft body 101 is provided with a convex ring part 104, and the metal layer 103 is arranged on the convex ring part 104, so that the metal layer 103 can be more firmly attached to the surface of the shaft body 101. The first rotating arm 3 is disposed between the two first sliding grooves 11, and the second rotating arm 4 is disposed between the two second sliding grooves 21, so that the movement of the first and second rotating arms is more stable.

The automobile door hinge can further improve the structural strength of the hinge, is not easy to disengage when bearing load, and has better safety; in addition, the material consumption is not greatly increased, and the cost is controllable.

It should be noted that the above-mentioned preferred embodiments are merely illustrative of the technical concepts and features of the present invention, and are intended to enable those skilled in the art to understand the contents of the present invention and implement the present invention, and not to limit the scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
