The second power source is connected to the fixing plate, and the second telescopic part of the second power source is pivotally connected to the mating rod pivot. The mating rod is parallel to the trunk lid, and the two ends of the mating rod are respectively connected to the connecting arm.

[0005] In some embodiments, the fixing plate and the trunk lid are respectively provided with a first positioning plate, a second positioning plate and a third positioning plate which are parallel to each other. The first power source is connected between the first positioning plate and the second positioning plate through a first pivot, and the connecting arm is connected between the second positioning plate and the third positioning plate through a second pivot.

[0006] In some embodiments, the first pivot and the second pivot are arranged in parallel.

[0007] In some embodiments, the fixing plate is provided with a fourth positioning plate and a fifth positioning plate, and the second power source is connected between the fourth and fifth positioning plates through a third pivot.

[0008] In some embodiments, the third pivot and the first pivot are arranged in parallel.

[0009] In some embodiments, the second power source is located in the middle of adjacent first power sources.

[0010] In some embodiments, the length of the first telescopic part is greater than that of the second telescopic part.

[0011] In some embodiments, the connecting arm is V-shaped and is arranged parallel to the first power source.

[0017] 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.

[0018] Such as Figures 1 to 4As shown in the figure, a hinge device for an automobile trunk lid according to this embodiment includes a first hinge assembly 1 and a second hinge assembly 2. The first hinge assembly 1 and the second hinge assembly 2 are respectively arranged between the trunk lid 10 and the fixing plate 20. The fixing plate 20 can be connected to the vehicle body. Through the first and second hinge assemblies, the trunk lid 10 can be flipped relative to the fixing plate 20. The second hinge assembly 2 is arranged between two groups of the first hinge assemblies 1. The first hinge assembly 1 includes a first power source 11 and a connecting arm 12. The first power source 11 is connected to the fixing plate 20. The first telescopic part 111 of the first power source 11 is pivotally connected to the trunk lid 10. Two ends of the connecting arm 12 are respectively pivotally connected to the trunk lid 10 and the fixing plate 20. The second hinge assembly 2 includes a second power source 21 and a mating rod 22. The second power source 21 is connected to the fixing plate 20. The second telescopic part 211 of the second power source 21 is pivotally connected to the mating rod 22. The mating rod 22 is parallel to the trunk lid 10. Two ends of the mating rod 22 are respectively connected to the connecting arm 12. In the above technical solution, when the trunk lid 10 is in the closed state (as Figure 2 shown), the first telescopic part 111 of the first power source 11 extends out to push the trunk lid 10 to maintain a vertical position. When the trunk lid 10 needs to be opened, the first telescopic part 111 contracts, and the trunk lid 10 flips outwards to open (as Figure 3 shown). At this time, the trunk lid 10 can be opened to a horizontal position. When goods need to be placed, the second telescopic part 211 of the second power source 21 can be extended to push the mating rod 22 to drive the connecting arm 12 to flip, so that the first hinge assembly 2 flips, and the trunk lid 10 is lowered to be close to the ground, thereby facilitating the handling of goods. Through the above technical solution, the trunk lid can be controlled to be stable at multiple positions, which is convenient for the handling of goods.

[0019] In this embodiment, the fixed plate 20 and the trunk lid 10 are respectively provided with first positioning plates 31, second positioning plates 32 and third positioning plates 33 that are parallel to each other. The first power source 11 is connected between the first positioning plate 313 and the second positioning plate 32 through a first pivot 41, and the connecting arm 12 is connected between the second positioning plate 32 and the third positioning plate 33 through a second pivot 42. Through the above technical solution, the connecting arm 12 and the first power source 11 can rotate relative to the fixed plate. The first pivot 41 and the second pivot 42 are arranged in parallel. The fixed plate 20 is provided with a fourth positioning plate 34 and a fifth positioning plate 35, and the second power source 21 is connected between the fourth and fifth positioning plates through a third pivot 43, so that the second power source 21 can rotate relative to the fixed plate. The third pivot 43 is arranged in parallel with the first pivot 41, so as to ensure the same rotation direction. The second power source 21 is located in the middle of adjacent first power sources 11, so that the trunk lid 10 rotates more smoothly. Both the first power source 11 and the second power source 21 adopt air cylinders or oil cylinders. The length of the first telescopic part 111 is greater than the length of the second telescopic part 211, and the first telescopic part 111 can push the trunk lid 10 to close. The connecting arm 12 is V-shaped, and the connecting arm 12 is arranged in parallel with the first power source 11.

[0020] A hinge device for an automobile trunk lid according to this embodiment can control the trunk lid to remain stable at multiple positions, and can be turned down to open, and can be closer to the ground, which is convenient for handling goods.
