[0018] Next, with reference to examples, the substantial features and advantages of the present utility model will be further described, but the present utility model is not limited to the listed embodiments.

[0019] Such as Figures 1 to 6As shown in the figure, a vehicle trunk hinge according to this embodiment includes a first connecting plate 1, a second connecting plate 2, and an adapter plate 3 disposed between the first and second connecting plates. The first connecting plate 1 and the second connecting plate 2 are arranged in parallel, and the adapter plate 3 is perpendicular to the first and second connecting plates. The first connecting plate 1 is provided with a first shaft hole 11 and a second shaft hole 12 arranged coaxially. There is a groove 13 between the first shaft hole 11 and the second shaft hole 12, and the groove 13 is arranged on the first connecting plate 1. A sleeve 14 is arranged in the first and second shaft holes. The sleeve 14 is provided with a lubricating oil passage 141. A pivot 15 is arranged in the sleeve 14. One end of the pivot 15 is provided with an end head 16, and the end head 16 is provided with an oil groove 161, and the oil groove 161 communicates with the lubricating oil passage 141. The outer wall of the second connecting plate 2 is provided with protrusions 21, and there are mounting holes 22 between several protrusions 21, and the mounting holes 22 are located in the middle of the second connecting plate 2. In the above technical solution, the first connecting plate 1 is connected to the cover plate 10 of the trunk, and the second connecting plate 2 is connected to the vehicle body 20. The two protrusions 21 are correspondingly arranged with the notches on the vehicle body, so as to facilitate the installation and positioning of the second connecting plate 2, and then the screw 4 is locked into the mounting hole 22 for fixation. The convex block 101 on the cover plate 10 corresponds to the groove 13, and the pivot 15 and the sleeve 14 pass through the first and second shaft holes and the convex block 101, so that the cover plate 10 can rotate relatively. By providing the lubricating oil passage 141, the lubricating oil can be in the lubricating oil passage, making the rotation smoother. Through the oil groove 161 of the end head 16, it is convenient to add lubricating oil. Through the above technical solution, the connection between the hinge and the cover plate and the vehicle body can be made more stable, the cover plate rotates more smoothly, the durability is improved, and the rotation noise can be avoided.
