[0030] <Example 1>

[0031] like Figures 1 to 6As shown, this embodiment provides a vehicle sliding door hinge, including an mounting part 1, a linkage part 2, a support member 3, and a connector 4. The mounting part 1 is disposed on the door body 10, serving as the fixing and guiding carrier of the hinge. The mounting part 1 is elongated and fixedly disposed inside the door body 10 of the sliding door. The linkage part 2 is slidably disposed in the first groove 11 of the mounting part 1. In this embodiment, the first groove 11 is a straight groove, a recess formed along the length of the mounting part in the middle, used to accommodate the linkage part and provide guidance for the sliding of the linkage part 2. The linkage part 2 has a protrusion 21, with receiving cavities 5 on both sides of the protrusion 21, used to accommodate the connector 4 when the door is closed, ensuring that the connector 4 is fully embedded in the linkage part 2 without occupying additional space. The linkage part 2 has a second groove 22, which is disposed in the same direction as the mounting part 1, and limiting grooves 23 are provided on both sides of the second groove 22. One end of the support member 3 is pivotally connected to the connector 4, and the other end is disposed in the second groove 22 and extends into the limiting groove 23, restricting the rotation direction of the support member 3 and ensuring that the support member 3 only slides and rotates around the axis along the length direction of the second groove 22. One end of the connector 4 is pivotally connected to the linkage part 2, and the other end is pivotally connected to the vehicle body 20, allowing the door 10 to rotate relative to the vehicle body when opening and closing. The connector 4 has a mounting groove 41, and one end of the support member 3 is located in the mounting groove 41 and pivotally connected to the connector 4. When the door is closed, the support member 3 is accommodated in the mounting groove 41, and the connector 4 is accommodated in the receiving cavity 5. Through the above technical solution, when the door is closed, the support member 3 and the connector 4 will not protrude from the mounting part 1, thereby making the structure more compact and reducing space occupation. When the door is open, the support member 3 and the connector 4 rotate in opposite directions, so that the support member 3, the connector 4 and the linkage part 2 form a triangle, forming a stable support structure, making the door more stable.

[0032] Specifically, the first groove 11 has positioning grooves 12 on both sides, and the linkage part 2 has extensions 24 at both ends. The extensions 24 are disposed in the limiting grooves 23 and are shafts, allowing them to slide and rotate relative to the positioning grooves 12. The protrusion 21 is disposed between the two opposing limiting grooves 23. The height of the protrusion 21 is not higher than the upper plate 121 of the positioning groove 12. When the door is closed, the thickness of the connector 4 is not higher than the upper plate 121 of the limiting groove 12. When the door is closed, the height of the protrusion and the thickness of the connector are not higher than the upper plate 121 of the positioning groove 12 of the mounting part, and the hinge has no protruding parts, allowing the door to close tightly. In this embodiment, the support 3 and the connector 4 are both flat, reducing their thickness and facilitating their placement in the mounting part 1.

[0033] In this embodiment, a vehicle sliding door hinge provides that, when the door is opened, the connecting member 4 rotates around the vehicle body 20 and the linkage part 2, and the support member 3 rotates around the connecting member 4 and the linkage part 2, with both rotating in opposite directions (e.g., ...). Figure 3(As indicated by the arrow), a triangular support structure is finally formed; when the door is closed, the two rotate in opposite directions to reset, the support 3 is retracted into the mounting groove 41, and the connector 4 is retracted into the receiving cavity 5 of the linkage part 2, so as to avoid protruding outward from the mounting part, resulting in a compact structure.

[0034] <Example 2>

[0035] In this embodiment, the parts that are the same as in Embodiment 1 are given the same reference numerals, and the same text descriptions are omitted.

[0036] like Figures 7 to 11 As shown, compared to Embodiment 1, the vehicle sliding door hinge provided in this embodiment has the following structural design differences:

[0037] In this embodiment, the connector 4 is connected to the vehicle body 20 via a first screw 61, and the support 3 is connected to the mounting groove 41 via a second screw 62. The first screw 61 and the second screw 62 are arranged parallel to each other and have the same thread direction. When the door is opened, the connector 4 and the support 3 rotate in different directions, causing them to displace in different directions. The connector 4 moves upward along the first screw 61, and the support 3 moves downward along the second screw 62, thereby increasing the contact area between the support 3 and the connector 4 and improving the support effect.

[0038] Furthermore, the first groove 11 includes a straight segment 111 and an oblique segment 112 connected to the straight segment 111. When the door is opened, one end of the support member 3 slides to the oblique segment 112. The oblique segment 112 and the straight segment 111 have a certain angle, allowing the support member 3 to slide into position. As those skilled in the art will know, the longitudinal displacement of the support member 3 and the connecting member 4 is a small range of displacement, about a few millimeters, and the angle is a small angle, about 3°. The schematic diagram has been enlarged to provide better differentiation.

[0039] In the above embodiments one and two, during the working process, depending on the different working environments, some of the technical implementation methods of embodiments one and two can be combined or replaced.

[0040] The technical principles of this utility model have been described above in conjunction with specific embodiments. However, it should be noted that these descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, other specific embodiments or equivalent substitutions of this utility model that can be conceived by those skilled in the art without creative effort will all fall within the scope of protection of this utility model.
