[0024] Figure 1 It is a structural schematic diagram of a hinge structure of a split-type rear door in an embodiment of the utility model.

[0025] like Figure 1 As shown, the hinge structure of the split-type tailgate provided by the present invention includes a hinge assembly 10 and a buffer unit 20 .

[0026] The hinge assembly 10 includes a fixed leaf 11 and a rotating leaf 12 . The fixed leaf 11 is arranged on the vehicle body, and the rotating leaf 12 is arranged on the rear door. The rotating leaf 11 and the fixed leaf 12 are rotatably connected by a hinged manner.

[0027] The fixing page 11 is plate-shaped, and a first connecting protrusion 111 is provided on one side of the fixing page 11 . The first connecting protrusion 111 is cylindrical, and an outer peripheral surface of the first connecting protrusion 111 is connected to one side of the fixing page 11 . A first connecting hole 112 is opened on the first connecting protrusion 111 .

[0028] The rotating leaf 12 includes an arc plate 121 and a connecting plate 122 . The arc plate 121 is provided with a second connecting protrusion 123 matched with the first connecting protrusion 111 . The connecting plate 122 is connected to a side of the arc plate 121 away from the second connecting protrusion 123 .

[0029] Figure 2 It is a cross-sectional view of the connection between the fixed page and the rotating page in the embodiment of the utility model.

[0030] The second connecting protrusion 123 is cylindrical and is located at the end of the arc plate 121. The two second connecting protrusions 123 are coaxially arranged at both ends of the arc plate 121 and are located on both sides of the first connecting protrusion 111. The first connecting protrusion 111 and the second connecting protrusion 123 are coaxial. The second connecting protrusion 123 is provided with a second connecting hole 124 adapted to the first connecting hole 112. The first connecting hole 112 and the second connecting hole 124 are coaxial. Figure 2 As shown, a pin shaft 13 is passed through the first connecting hole 112 and the second connecting hole 124, and limiting protrusions 131 are provided at both ends of the pin shaft 13. The limiting protrusions 131 abut against the second connecting protrusions 123 to fix the pin shaft 13 in the first connecting hole 112 and the second connecting hole 124, so that the rotating page 11 and the fixed page 12 are rotatably connected by a hinged manner, which is convenient for the operator to open the double-leaf tailgate.

[0031] The buffer unit 20 is disposed on the rotating page 12 and abuts against the fixed page 11. The buffer unit 20 includes a buffer block 21, an end of which is connected to the second connection protrusion 123, the buffer block 21 is in a rectangular parallelepiped shape, and both sides of the buffer block 21 are connected to the two second connection protrusions 123, so as to be disposed on the rotating page 12. The buffer block 21 is made of rubber and has good buffering performance.

[0032] Figure 3 It is a cross-sectional view of a buffer block in an embodiment of the present utility model.

[0033] like Figure 3As shown, a clamping protrusion 125 is provided on the second connecting protrusion 123, a protrusion 211 adapted to the clamping protrusion 125 is provided on the buffer block 21, a clamping head 212 is provided on the protrusion 211, the clamping protrusion 125 and the protrusion 211 are clamped with each other, so that the buffer block 21 is clamped on the rotating page 12, and the clamping head 212 abuts against the clamping protrusion 125, so as to enhance the connection strength between the buffer block 21 and the rotating page 12 and prevent the buffer block 21 from falling off.

[0034] The buffer block 21 is located at the arc plate 121 of the rotating leaf 12, and the arc plate 121 is bent in a direction away from the buffer block 21, thereby preventing the buffer unit 20 from interfering with the operation of the hinge assembly 10 and reducing the opening and closing angle of the double-opening tailgate.

[0035] The fixed page 11 is provided with a first mounting hole 113, and a screw is screwed into the first mounting hole 113 to mount the fixed page 11 on the vehicle body; the rotating page 12 is provided with a second mounting hole 126, and a screw is screwed into the second mounting hole 126 to mount the rotating page 12 on the tailgate.

[0036] Figure 4 1 is a schematic structural diagram of a hinge structure of a split rear door in a state where the split rear door is closed in an embodiment of the utility model; Figure 5 It is a structural schematic diagram of the hinge structure of the split rear door in the embodiment of the utility model when the split rear door is in an open state.

[0037] like Figure 4 and Figure 5 As shown, when the double-leaf tailgate is in the closed state, the fixed page 11 and the rotating page 12 are away from each other. When the double-leaf tailgate is in the open state, the double-leaf tailgate drives the rotating page 12 to rotate, so that the buffer block 21 rotates toward the fixed page 11. The buffer block 21 is connected to the fixed page 11, thereby buffering the impact between the fixed page 11 and the rotating page 12, avoiding deformation of the hinge assembly 10 under impact, thereby improving the reliability of the structure and extending the service life.
