[0029] The utility model provides a kind of automobile tail door reinforced hinge with simple structure and high strength, by connecting tail door hinge reinforcing plate 3 on tail door hinge base plate 1, improve the carrying capacity of automobile tail door with spare tire, so that spare tire is relied on on tail door reinforced hinge, so that original car tail door no longer bears the weight of spare tire, increase the strength of tail door, improve the service life of vehicle accessories, and by connected mounting component and automobile tail door connection, eliminate the stress concentration defects of traditional split structure, tail door is not easy to deform, and fatigue resistance is improved.

[0030] In this embodiment, the tail gate hinge base plate 1 and the tail gate hinge reinforcing plate 3 are integrally arranged, and the tail gate hinge base plate 1 and the tail gate hinge reinforcing plate 3 are integrally processed and formed.

[0031] Specifically, by arranging the integrally formed tail gate reinforcing hinge, the welding or splicing weak points are eliminated, the overall strength is improved, the risk of fracture is eliminated, the strength of the tail gate hinge is greatly improved, the load bearing capacity of the off-road vehicle tail gate with a spare tire is higher; and the innovative composite process is adopted, the tail gate reinforcing hinge is combined with the full aluminum spinning casting process and the alloy steel casting process, which can have higher fatigue resistance, deformation resistance, noise resistance and higher load bearing capacity in the off-road road conditions; the combination of full aluminum spinning casting and alloy steel precision casting not only reduces the tail gate load and improves the control flexibility, but also strengthens the key stress part and improves the impact resistance.

[0032] In this embodiment, as shown in Figure 2 The mounting mechanism 2 is arranged at the first end of the tail gate hinge base plate 1 in the length direction, and is arranged in the axial direction along the short side of the base plate. The mounting mechanism 2 includes a first mounting portion 21 and a second mounting portion 22. The first mounting portion 21 and the second mounting portion 22 are arranged in the same vertical plane and in the same axial direction. The spacing between them is the base plate mounting space.

[0033] Specifically, the first mounting portion 21 and the second mounting portion 22 are arranged at the first end of the tail gate hinge base plate 1. The first mounting portion 21 is arranged at the upper part, and the second mounting portion 22 is arranged at the lower part. The first mounting portion 21 and the second mounting portion 22 are connected in a connected structure. The automobile tail gate is provided with a mounting matching component matched with the first mounting portion 21 and the second mounting portion 22. The tail gate hinge base plate 1 is rotatably connected with the automobile tail gate through the mounting mechanism 2.

The automobile tail gate is provided with a hinge connection structure matched with the connected hinge structure. The first mounting portion 21 and the second mounting portion 22 are arranged at the upper and lower ends of the hinge integrated structure. By adopting the double hinge connection structure, the spare tire and load pressure are dispersed to the vehicle body frame, the load bearing burden of the tail gate is reduced, and the first mounting portion and the second mounting portion are integrated structures and are in communication with each other. The problems of uneven stress and easy deformation of the conventional upper and lower separated hinge connection structure are changed. The upper and lower hinges and the tail gate hinge base plate are integrally formed by using the whole precision machining process. The stress concentration points of the traditional split structure are eliminated, the connection support area is strengthened, the deformation is avoided during long-term use, the problems of door body sagging and poor opening and closing are avoided, and the service life of the tail gate reinforcing hinge is prolonged.

The reinforced hinge can better bear these forces, ensure the stability of the tail door, reduce deformation and damage caused by long-term vibration, and prolong the service life of the tail door.

[0036] Furthermore, the double-hinge structure is also convenient for modification and upgrading. For off-road vehicle enthusiasts who have modification needs, the reinforced hinge of the double-hinge structure provides a better foundation for subsequent modification.
