[0015] The essential features and advantages of the present invention are further described below in conjunction with examples, but the present invention is not limited to the examples listed.
[0016] like Figures 1 to 3 As shown, a sliding door hinge for automobiles in this embodiment comprises a first connection part 1 and a second connection part 2, wherein the first and second connection parts are connected to the sliding door and the vehicle body respectively, and a rotating assembly 3 is arranged between the first connection part 1 and the second connection part 2, so that the first and second connection parts can rotate relative to each other. The rotating assembly 3 comprises a fitting 4 and a rotating plate 5, wherein the two ends of the fitting 4 are respectively pivotally connected to the first connection part 1 and the second connection part 2. A plurality of rotating plates 5 are stacked and arranged, so that the connection strength can be adjusted by adjusting the number of rotating plates 5. The rotating plate 5 is pivotally connected to the second connection part 2, and the two ends of the rotating plate 5 are provided with shaft holes 51, and an arc portion 52 is provided between the shaft holes 51. The second connection part 2 is provided with a cylinder 6, and a telescopic rod 61 of the cylinder 6 is pivotally connected to a first rotating part 71, and the first rotating part 71 is pivotally connected to the second connection part 2 and the second rotating part 72 respectively, and the second rotating part 72 is pivotally connected to the rotating plate 5. The fitting 4 is provided with a spring 8, and the foot 81 of the spring 8 is respectively against the stopper 52 of the fitting 4 and the rotating plate 5. In the above technical solution, when the sliding door is closed, the foot 81 of the spring 8 is stretched out (such as Figure 1) The spring 8 accumulates elastic force. When opened, the elastic force of the spring 8 is released, driving the mating part 4 and the rotating plate 5 to rotate, facilitating the opening of the sliding door. The first and second rotating parts are driven to rotate by the rotating plate 5, causing the telescopic rod 61 of the cylinder 6 to extend during the rotation process. The telescopic rod 61 provides damping to prevent the sliding door from moving too fast. Through the above technical solution, the connection strength can be adjusted by adjusting the number of rotating plates, facilitating the opening of the sliding door, and damping effect can be provided.
[0017] In this embodiment, the second connecting part 2 has a positioning seat 21. The cylinder 6 is arranged in the positioning seat 21. The positioning seat 21 is connected to the mating part 4 through the first rotating shaft 10, enabling the mating part 4 to rotate around the first rotating shaft 10. The spring 6 is sleeved on the first rotating shaft 10, facilitating the positioning and installation of the spring 6. The rotating plate 5 is connected to the positioning seat 21 through the second rotating shaft 20, enabling the rotating plate 5 to rotate around the second rotating shaft 20. The second rotating shaft 20 is arranged in the limiting part 52. The two limiting parts 52 are located at the upper and lower parts of the rotating plate 5. The plurality of rotating plates 5 are positioned together through the limiting parts 52. The foot part 61 of the spring 8 abuts against the limiting part 52, facilitating the positioning of the foot part 61. The first rotating part 71 has three through holes 711. The three through holes 711 respectively correspond to the three pivot shafts 30. The three pivot shafts 30 are respectively connected to the telescopic rod 61, the positioning seat 21, and the second rotating part 72, enabling the first rotating part 71 to link the above components through multiple pivot shafts and drive the telescopic rod 61. The three through holes 711 are arranged in a triangular pattern. The cross-section of the mating part 4 is U-shaped. The foot part 61 of the spring is located in the U-shaped groove 41 of the mating part 4, enabling the foot part 61 to abut against the mating part 4.
[0018] An automotive sliding door hinge of this embodiment can provide damping to prevent damage to the door hinge, adjust the connection strength by adjusting the number of rotating plates, provide auxiliary power for opening the door, and facilitate the opening of the sliding door.
