[0017] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.
[0018] See also Figures 1 to 4 The utility model provides a tailgate hinge with excellent over-opening stop and limiting performance, including a fixing plate 1, two fixing blocks 2, a round rod 3, a connecting piece 4, a mounting piece, a buffer block 6 and two clamping columns 7. The two fixing blocks 2 are fixedly connected to the fixing plate 1 and are located on both sides of the fixing plate 1. The round rod 3 passes through the two fixing blocks 2. The connecting piece 4 is rotatably connected to the round rod 3 and covers the surface of the round rod 3. The mounting piece is fixedly connected to the connecting piece 4 and is located on one side of the connecting piece 4. Two mounting holes 5 are provided at one end of the fixing plate 1. One end of the two clamping columns 7 is clamped with the corresponding mounting holes 5, and the buffer block 6 is fixedly connected to the clamping column 7.
[0019] In this embodiment, the buffer block 6 is clamped on the fixing plate by the clamping column 7. When the car door is rotated, the mounting part rotates around the round rod 3, and the mounting part is pressed on the buffer block 6 to achieve a stop limit. When the door opening force is too large, the buffer block 6 prevents the fixing plate and the mounting part from colliding.
[0020] Furthermore, a plurality of clamping strips 8 are provided at one end of the round rod 3 , and the plurality of clamping strips 8 are evenly arranged at one end of the round rod 3 , and the clamping strips 8 are clamped with the corresponding fixing blocks 2 .
[0021] In this embodiment, the round rod 3 is fixed to the fixing block 2 by a plurality of the clamping strips 8 , so that the mounting member is more stable when rotating around the round rod 3 .
[0022] Furthermore, the mounting member includes a mounting plate 9, a connecting plate 10 and a transition plate 11. The connecting plate 10 is fixedly connected to the connecting plate 4 and is located on one side of the buffer block 6. The connecting plate 10 is L-shaped, and one end of the transition plate 11 is fixedly connected to the connecting plate 10, and the other end of the transition plate 11 is fixedly connected to the mounting plate 9.
[0023] In this embodiment, when the vehicle door is opened or closed, the connecting plate 10 contacts the buffer block 6, thereby increasing the contact surface. At the same time, the mounting plate 9 is fixed to the vehicle door, thereby improving the opening and closing accuracy of the vehicle door.
[0024] Furthermore, the tailgate hinge with excellent over-opening stop limiting performance further includes three fixing pins 12 , which are fixedly connected to the fixing plate 1 and are located on one side of the fixing plate 1 .
[0025] In this embodiment, the fixing pin 12 fixes the fixing plate 1 to the vehicle body so that the two fixing blocks 2 and the round rod 3 are close to the vehicle door. When the hinge is fully opened, the contact surface between the fixing plate 1 and the connecting plate 10 is large, and there is a large enough area to arrange the buffer block 6.
[0026] Furthermore, three mounting holes 5 are provided on the surface of the mounting plate 9 .
[0027] In this embodiment, the provision of the three mounting holes 5 facilitates fixing the mounting plate 9 on the vehicle door.
[0028] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention.
