DETAILED DESCRIPTION

[0054] The technical solutions in the embodiments of the present application will be described clearly and completely in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present application.

[0055] The present application provides a connecting structure, Figures 1 to 5For some embodiments of the present application.

[0056] Please refer to Figures 1 to 2 In some embodiments of the present application, the connecting structure comprises a first mounting part 1 and a movable part 2, the first mounting part 1 is configured to be mounted on the vehicle body, the movable part 2 is arranged on the first mounting part 1 along the first direction X and can rotate relative to the first mounting part 1, and the movable part 2 is configured to be connected with the tail gate; wherein the tail gate in the present embodiment is a lower tail gate in the related art, and the cooperation of the first mounting part 1 and the movable part 2 enables the lower tail gate to move relative to the vehicle body.

[0057] Wherein, the movement of the movable part 2 along the first direction X can drive the lower tail gate to move towards or away from the upper tail gate along the first direction X, that is, to prevent the lower tail gate from interfering with the upper tail gate during rotation opening and closing; and the movable part 2 can also rotate relative to the first mounting part 1, so that the lower tail gate can be rotated to open and close.

[0058] In some embodiments of the present application, the first direction X is a height direction.

[0059] When the upper tail gate is in a closed state, the opening process of the lower tail gate is as follows: the movable part 2 drives the lower tail gate to move away from the upper tail gate along the first direction X until the lower tail gate does not interfere with the upper tail gate during rotation opening and closing, at this time the movable part 2 rotates relative to the first mounting part 1, thereby driving the lower tail gate to rotate to open, so as to realize the opening of the lower tail gate.

[0060] When the upper tail gate is in a closed state, the closing process of the lower tail gate is as follows: the movable part 2 rotates relative to the first mounting part 1, thereby driving the lower tail gate to rotate to close, and the movable part 2 drives the lower tail gate to move towards the upper tail gate along the first direction X until the lower tail gate is closed with the upper tail gate.

[0061] It can be understood that when the upper tail gate is in an open state, the opening and closing of the lower tail gate are also as described above; therefore, the lower tail gate does not need to adjust the upper tail gate when performing opening and closing actions.

[0062] In some embodiments of the present application, the connecting structure further comprises a driving part 3, the driving part 3 is connected with the movable part 2, and the driving part 3 is configured to drive the movable part 2 to move along the first direction X and to rotate; that is, the driving part 3 drives the movable part 2 to move, thereby realizing the opening and closing of the lower tail gate.

[0063] In the technical solution of the present application, the driving part 3 is arranged to drive the movable part 2 to move on the first mounting part 1, so that the lower tail door moves away from the upper tail door in the first direction X before being opened, and the lower tail door will not interfere with the upper tail door when the driving part 3 drives the movable part 2 to rotate relative to the first mounting part 1 to open the lower tail door. Similarly, the lower tail door will not interfere with the upper tail door when the movable part 2 rotates to close the lower tail door. That is, the opening and closing operation of the lower tail door does not need to be coordinated with the opening and closing operation of the upper tail door, and the connecting structure in the embodiment of the present application can realize the independent opening and closing of the lower tail door.

[0064] It should be noted that the movable part 2 can rotate relative to the first mounting part 1, and part of the movable part 2 can rotate relative to the first mounting part 1, or the entire movable part 2 can rotate relative to the first mounting part 1, which is not limited here.

[0065] In some embodiments of the present application, the movable part 2 includes a first sub-part 21 and a second sub-part 22, the first sub-part 21 is connected with the first mounting part 1 and can move in the first direction X, the second sub-part 22 is connected with the second mounting part and can rotate relative to the first sub-part 21, and the second sub-part 22 is configured to be connected with the tail door; wherein the movement of the first sub-part 21 in the first direction X can drive the lower tail door to move towards or away from the upper tail door in the first direction X, that is, to prevent the lower tail door from colliding with the upper tail door before being opened, and the second sub-part 22 can rotate relative to the first sub-part 21, so that the lower tail door can be opened and closed by rotation; in summary, the design of the first sub-part 21 and the second sub-part 22 makes the opening and closing operation of the lower tail door independent of the opening and closing operation of the upper tail door.

[0066] When the upper tail door is in a closed state, the opening process of the lower tail door is as follows: the first sub-part 21 drives the lower tail door to move away from the upper tail door in the first direction X until the lower tail door does not collide with the upper tail door when rotating, and the second sub-part 22 rotates relative to the first sub-part 21, thereby driving the lower tail door to rotate and open, to realize the opening of the lower tail door.

[0067] When the upper tail door is in a closed state, the closing process of the lower tail door is as follows: the second sub-part 22 rotates relative to the first sub-part 21, thereby driving the lower tail door to rotate and close, and the first sub-part 21 drives the lower tail door to move towards the upper tail door in the first direction X until the lower tail door is closed with the upper tail door.

[0068] In some embodiments of the present application, the driving part 3 is configured to drive the first sub-part 21 to move in the first direction X and drive the second sub-part 22 to rotate; that is, the driving part 3 drives the first sub-part 21 and the second sub-part 22 to move respectively, thereby realizing the independent opening and closing of the lower tail door.

[0069] It should be noted that the first sub-portion 21 can be arranged at any position of the first mounting portion 1, for example, in an embodiment of the present application, the first sub-portion 21 can be arranged inside the first mounting portion 1; in another embodiment of the present application, the first sub-portion 21 can be arranged on the outer surface of the first mounting portion 1; and the like. The relative position relationship between the first sub-portion 21 and the first mounting portion 1 can be adjusted and designed according to the vehicle model of different vehicles, as long as the first sub-portion 21 is connected to the first mounting portion 1 and can move along the first direction X.

[0070] Similarly, the second sub-portion 22 can be arranged at any position of the first sub-portion 21, for example, in an embodiment of the present application, the second sub-portion 22 can be arranged inside the first sub-portion 21; in another embodiment of the present application, the second sub-portion 22 can be arranged on the outer surface of the first sub-portion 21; and the like. The relative position relationship between the first sub-portion 21 and the second sub-portion 22 can be adjusted and designed according to the vehicle model of different vehicles, as long as the first sub-portion 21 is connected to the second sub-portion 22 and the second sub-portion 22 can rotate relative to the first sub-portion 21.

[0071] In some embodiments of the present application, the driving portion 3 can be connected to the first sub-portion 21 and the second sub-portion 22 respectively to realize the movement of the first sub-portion 21 along the first direction X and the rotation of the second sub-portion 22; or can be connected to one of the first sub-portion 21 and the second sub-portion 22 to realize the movement of the first sub-portion 21 along the first direction X and the rotation of the second sub-portion 22; for example, in an embodiment, the driving portion 3 is connected to the second sub-portion 22, drives the first sub-portion 21 to move along the first direction X through the second sub-portion 22, and can limit or release the rotation of the second sub-portion 22.

[0072] In some embodiments of the present application, the driving portion 3 is connected to the second sub-portion 22; the driving portion 3 drives the second sub-portion 22 to move along the first direction X, and the second sub-portion 22 drives the first sub-portion 21 to move along the first direction X; that is, in this embodiment, the driving portion 3 is connected to the second sub-portion 22, drives the first sub-portion 21 to move along the first direction X through the second sub-portion 22, to realize the movement of the lower tail door away from or close to the upper tail door along the first direction X.

[0073] In the opening process of the lower tail door, when the lower tail door moves away from the upper tail door along the first direction X, the first sub-portion 21 moves along the first direction X, and the second sub-portion 22 can rotate to drive the lower tail door to open after moving a certain distance, and at this time the first sub-portion 21 still moves along the first direction X; or the second sub-portion 22 can rotate to drive the lower tail door to open after the first sub-portion 21 finishes moving along the first direction X.

[0074] Similarly, when the lower tail gate is closing, the second sub-portion 22 can rotate to drive the lower tail gate to rotate and close when the lower tail gate is moving towards the upper tail gate in the first direction X; or the second sub-portion 22 can rotate to drive the lower tail gate to rotate and close, and then drive the lower tail gate to move towards the upper tail gate in the first direction X.

[0075] Please refer to Figures 1 to 2 , Figures 1 to 2 for a structure diagram of the connecting structure when the lower tail gate is in the closed state.

[0076] Please refer to Figures 3 to 4 , Figures 3 to 4 for a structure diagram of the connecting structure when the lower tail gate is in the open state.

[0077] That is, when the lower tail gate is open, the second sub-portion 22 is driven to rotate after the first sub-portion 21 finishes moving in the first direction X; when the lower tail gate is closing, the second sub-portion 22 is first rotated, and then the first sub-portion 21 moves in the first direction X.

[0078] Please refer to Figure 5 , in some embodiments of the present application, the driving portion 3 is rotationally connected with the second sub-portion 22, the driving portion 3 and the second sub-portion 22 have a first rotation axis 4, the second sub-portion 22 and the first sub-portion 21 have a second rotation axis 5, and the first rotation axis 4 and the second rotation axis 5 are not located on the same axis; in this way, when the driving portion 3 rotates around the second rotation axis 5 or the first sub-portion 21 rotates around the first rotation axis 4, the second sub-portion 22 can rotate, thereby driving the lower tail gate to rotate and open / close.

[0079] In some embodiments of the present application, a third connecting piece 14 is arranged on the second sub-portion 22, and the third connecting piece 14 is rotationally connected with the driving portion 3.

[0080] In some embodiments of the present application, a fourth connecting piece 15 is arranged on the second sub-portion 22, and the fourth connecting piece 15 is rotationally connected with the first sub-portion 21.

[0081] The third connecting piece 14 and the fourth connecting piece 15 are respectively located on opposite sides of the second sub-portion 22.

[0082] In some embodiments of the present application, the connecting structure further comprises a first guide piece 6, the first guide piece 6 is arranged on the first mounting portion 1 and extends in the first direction X, one end of the first sub-portion 21 is movably connected with the first guide piece 6 and can move in the extension direction of the first guide piece 6; that is, in this embodiment, the first sub-portion 21 can move relative to the first mounting portion 1 in the first direction X through cooperation with the first guide piece 6, so that the lower tail gate moves towards or away from the upper tail gate in the first direction X.

[0083] The first guide member 6 can be a guide rail or a guide groove, and is not limited herein.

[0084] In some embodiments of the present application, the first guide member 6 is a guide groove.

[0085] In some embodiments of the present application, the second sub-portion 22 is fixed relative to the first sub-portion 21 when the first sub-portion 21 moves along the extension direction of the first guide member 6. That is, in this embodiment, when the lower tail door moves towards or away from the upper tail door in the first direction X, the driving portion 3 restricts the rotation of the first sub-portion 21 and the second sub-portion 22 to avoid the lower tail door from rotating when moving in the first direction X, thereby avoiding interference with the upper tail door.

[0086] In some embodiments of the present application, the connecting structure further comprises a second guide member 7, which is arranged on the first mounting portion 1 and connected with the first guide member 6. The extension direction of the second guide member 7 intersects the first direction X.

When the first sub-portion 21 moves along the extension direction of the second guide member 7, the second sub-portion 22 rotates relative to the first sub-portion 21. In this embodiment, by arranging the second guide member 7 and the first sub-portion 21, that is, after the first sub-portion 21 moves relative to the first mounting portion 1 in the first direction X, the first sub-portion 21 further moves along the extension direction of the second guide member 7. At this time, the driving portion 3 restricts the movement of the second sub-portion 22 in the first direction X or drives the second sub-portion 22 to continue moving in the first direction X, thereby driving the second sub-portion 22 to rotate, and further realizing the rotation opening and closing of the lower tail door.

[0087] The second guide member 7 can be a guide rail or a guide groove, and is not limited herein.

[0088] In some embodiments of the present application, the second guide member 7 is a guide groove.
