A tailgate panel hinge fixing and limiting structure 5 is provided on the other side of the upper part of the car body 1.

[0022] The tailgate hinge mounting and positioning structure 4 includes mounting screws 41 and connecting seat 42. The connecting seat 42 is movably mounted on the upper part of the vehicle body 1. The connecting seat 42 is made of high-strength carbon steel. The connecting seat 42 can be fixedly installed by rotating and screwing the mounting screws 41 on the upper part of the vehicle body 1. Two mounting screws 41 are rotatably connected to the inner side of the connecting seat 42. Multiple insertion slots 43 are fixedly connected to the top of the connecting seat 42. The insertion slots 43 are multiple parallel triangular structures.

[0023] A fixed vertical plate 44 is fixedly connected to one side of the top of the connecting seat 42. The fixed vertical plate 44 is welded vertically to one side of the connecting seat 42. The fixed vertical plate 44, with the limiting top block 45 extending from the inner side, can form a groove structure for clamping the sliding plate 51 in cooperation with the connecting seat 42 below. The limiting top block 45 is fixedly connected to the inner wall of the fixed vertical plate 44. The lower ends of the two mounting screws 41 are threaded to the inner wall of the top of the vehicle body 1. Multiple insertion slots 43 are parallel and equidistant from each other.

[0024] The tailgate hinge fixing and limiting structure 5 includes a sliding plate 51 and a movable block 54. The movable block 54 is movably connected to one side of the top of the vehicle body 1. The movable block 54 can be installed and removed from the top of the vehicle body 1 using a second bolt 55. The inner side of the movable block 54 is threaded with a second bolt 55. A limiting baffle 53 is fixedly connected to one side of the movable block 54. The movable block 54, which can be detached and installed, can also be detached and installed on the other side above the connecting seat 42 with the limiting baffle 53.

[0025] The sliding plate 51 is movably connected to the inner side of the fixed vertical plate 44. Multiple splicing strips 52 are fixedly connected to the lower end of the sliding plate 51. The shape and specifications of the splicing strips 52 match the lower insertion groove 43. Thus, when determining and fixing the position of the sliding plate 51 and the hinge structure above the sliding plate 51, the sliding plate 51 is inserted into one end of the connecting seat 32. The splicing strips 52 and the corresponding positions of the insertion groove 43 are slidably engaged together. The sliding plate 51 can adjust the distance between the hinge structure and the rear side of the vehicle body 1 near the trunk door by using the different engagement positions of the splicing strips 52 and the insertion groove 43.

[0026] Finally, after the movable block 54 is tightened and fixed using the second bolt 55, the limiting baffle 53 and the limiting top block 45 on the other side will press down on the position of the sliding plate 51 to achieve fixation, which also facilitates replacement and adjustment after reverse disassembly. The top of the sliding plate 51 is fixedly connected to the lower end of the hinge seat 31.

[0027] One end of the sliding plate 51 is movably connected to the inner side of the limiting top block 45, and the other end of the sliding plate 51 is pressed against the inner side of the limiting baffle 53. The lower end of the splicing strip 52 is engaged with the insertion groove 43 at the top of the connecting seat 42.

[0028] Working principle:

[0029] A car tailgate hinge is a structure used to open and close the tailgate at the rear of a car. The hinge has a rotating axis that allows the tailgate to flip up or to the left or right around the rear of the car.

[0030] First, the hinge installation and positioning process is carried out:

[0031] The connecting seat 42 is made of high-strength carbon steel. The connecting seat 42 can be fixedly installed by rotating and screwing it into the upper part of the vehicle body 1 using the mounting screw 41 below. The insertion slot 43 has multiple parallel triangular structures. The fixing vertical plate 44 is welded vertically on one side of the connecting seat 42. The fixing vertical plate 44, with the limiting top block 45 extending from the inner side, can form a groove structure for clamping the sliding plate 51 in conjunction with the connecting seat 42 below.

[0032] Then proceed with the hinge installation and removal steps:

[0033] The movable block 54 can be installed and removed from the top of the vehicle body 1 using the second bolt 55. At the same time, the movable block 54, which can be installed and removed, can also be installed and removed from the other side above the connecting seat 42 with the limiting baffle 53. The shape and specifications of the splicing strip 52 match the lower insertion groove 43.

[0034] In this way, when determining and fixing the position of the sliding plate 51 and the hinge structure above the sliding plate 51, the sliding plate 51 is inserted into one end of the connecting seat 32, and the splicing strip 52 and the corresponding position of the insertion groove 43 are slidably engaged together. The sliding plate 51 can adjust the distance between the hinge structure and the rear side of the vehicle body 1 near the trunk door by using the different engagement positions of the splicing strip 52 and the insertion groove 43. Finally, after the movable block 54 is tightened and fixed by the second bolt 55, the limiting baffle 53 and the limiting top block 45 on the other side will press down on the position of the sliding plate 51 to achieve fixation, which also facilitates replacement and adjustment after reverse disassembly.

[0035] Example 2: Please refer to Figures 1-6 In this embodiment, a car tailgate hinge includes a car tailgate hinge connection structure 3 including a hinge seat 31 and a mounting hole 35. The mounting hole 35 is fixedly opened inside the top of the tailgate panel 2. A first bolt 34 is threadedly connected to the inner side of the mounting hole 35. The first bolt 34 can pass through the mounting hole 35 inside the flip hinge 32 and then be tightened with a nut 36 at the other end to achieve fixation.

[0036] The flip hinge 32 can be flipped inside the hinge seat 31 via the pivot pin 33, so that the other side of the flip hinge 32 can drive the tailgate panel 2 to rotate along the pivot pin 33. One end of the first bolt 34 is movably connected to the flip hinge 32, and the other side of the flip hinge 32 is rotatably connected to the pivot pin 33. The hinge seat 31 is rotatably connected to both ends of the pivot pin 33, and the other end of the first bolt 34 is threaded with a nut 36.

[0037] Working principle:

[0038] Mounting hole 35 is fixedly opened inside the top of tailgate panel 2. The inner side of mounting hole 35 is threaded with first bolt 34. First bolt 34 can be inserted into mounting hole 35 inside flip hinge 32 and then tightened with nut 36 at the other end to achieve fixation. Flip hinge 32 can be flipped inside hinge seat 31 through pivot pin 33. In this way, the other side of flip hinge 32 can drive tailgate panel 2 to rotate along pivot pin 33.
