It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.
Referring to fig. 1 and 2, the present invention provides a novel tailgate hinge structure, which includes a base 1, a first link 2, a second link 3, and a rotating arm 4; the base 1 is connected with the side wall of the vehicle body through a bolt 11, one side of the base 1, which is far away from the tail door of the vehicle body, is provided with a first connecting part 13, one end of a first connecting rod 2 is rotatably connected with two sides of the first connecting part 13 through a pin shaft, the middle position of the connecting part is also provided with a first connecting groove, and one end of a second connecting rod 3 is rotatably connected with the first connecting groove through a pin shaft;
the rotating arm 4 is provided with a connecting hole 42, the connecting hole 42 is used for being connected with a tail door of a vehicle body, one side of the rotating arm 4 close to the side wall of the vehicle body is provided with a second connecting part 41, the other end of the first connecting rod 2 is rotatably connected with two sides of the second connecting part 41 through a pin shaft, the middle position of the connecting part is also provided with a second connecting groove, and the other end of the second connecting rod 3 is rotatably connected with the second connecting groove through a pin shaft; the first link 2 is not coplanar with the second link 3, and the second link 3 is used for limiting the angle of rotation of the rotating arm 4 around the first link 2.
When the automobile tail door opening device is implemented, the automobile tail door can be effectively opened to a large opening degree state through the four-bar structure, and the automobile tail door opening device is convenient for users to use. The rotating angle between the base 1 and the rotating arm 4 is realized through the first connecting rod 2, so that the influence of the connection position of a tail door and a side wall on the large-angle opening and closing of the rotating arm 4 is avoided, the second connecting rod 3 limits the rotating angle of the rotating arm 4, the phenomenon that the angle of the second connecting rod is too large in opening and closing and is easy to damage due to collision with the side wall is avoided, an irregular quadrangle is formed between the four connection points of the second connecting rod 3 and the first connecting rod during rotation, when the tail door is attached to the side wall, two sides of the quadrangle form a straight edge, a stable triangular structure is formed, and the radial force applied to the connection point of the straight edge by the rotating arm 4 and the base 1 is used for improving the stability of the straight edge.
Furthermore, a bent portion 21 is disposed at a connection portion of the first connecting rod 2 and the first connecting portion 13, and the bent portion 21 is connected with the first connecting portion 13 through a pin shaft, so as to avoid that the first connecting rod 2 and the base 1 are overlapped in a closed state to cause an unclosed state.
Furthermore, the base 1 is provided with a positioning hole 12, and the side wall of the vehicle body is provided with a positioning column corresponding to the positioning hole 12, so that the base 1 and the side wall can be conveniently installed.
Further, when the tail door is closed, the first link 2 and the second link 3 are both parallel to the base 1. In practice, the first connecting rod 2 can be parallel to the base 1 through the bending portion 21, and the second connecting rod 3 can be parallel to the base 1 through the bending of the first connecting portion 13 or the bending of itself.
Further, the second connecting portion 41 has a triangular shape, and the rotation arm 4 is connected to a corner of the second connecting portion 41 and is collinear with one side of the second connecting portion 41.
Still further, the first link 2 is connected with the other corner of the second connecting portion 41 and the swivel arm 4 which are collinear; the second link 3 is connected to the last corner of the second connecting portion 41. In practice, the rotating arm 4, the first link 2 and the second link 3 are respectively connected with three corners of the second connecting part 41, so that the first link 2 and the second link 3 are not coplanar, and the first link 2 and the rotating arm 4 are collinear, and the first link 2 is vertical to the rotating arm 4 when the tail gate is closed; when the tailgate is unfolded, the first link 2 is parallel to the tailgate.
In implementation, when the present invention is in the unfolded state shown in fig. 2, the connection points of the second connecting rod 3 and the first connecting rod 2 with the first connecting portion 13 are collinear, and are not collinear with the connection point of the second connecting portion 41, so that a stable triangle is formed between the two, and at this time, the tail gate is attached to the side wall, so that the problem that the tail gate is automatically closed due to the blowing of wind on the tail gate can be prevented; in addition, if the second connecting portion 41 rotates singly, it will be resisted by the second link 3, so that the single rotation of the second connecting portion 41 cannot be realized, and the tail gate cannot rotate and close independently; when the tail gate needs to be closed, the first connecting rod 2 and the second connecting rod 3 need to be pulled by the tail gate to rotate around the first connecting part 13, so that the closing of the tail gate can be realized.
Although some specific embodiments of the present invention have been described in detail by way of examples, it should be understood by those skilled in the art that the above examples are for illustrative purposes only and are not intended to limit the scope of the present invention. It will be appreciated by those skilled in the art that modifications may be made to the above embodiments without departing from the scope and spirit of the invention. The scope of the invention is defined by the appended claims.
