[0054] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0055] This application proposes a connection structure. Figures 1 to 5These are some embodiments of the present application.

[0056] See also Figure 1 to Figure 2 In some embodiments of the present application, the connection structure includes a first mounting portion 1 and a movable portion 2, the first mounting portion 1 is configured to be mounted on a vehicle body, the movable portion 2 is disposed on the first mounting portion 1 along a first direction X and can rotate relative to the first mounting portion 1, and the movable portion 2 is configured to be connected to a tailgate; wherein the tailgate in this embodiment is a lower tailgate in the related art, and the cooperation between the first mounting portion 1 and the movable portion 2 enables the lower tailgate to move relative to the vehicle body.

[0057] The movable portion 2 can move along the first direction X to drive the lower tailgate to move closer to or away from the upper tailgate in the first direction X, so that the lower tailgate will not interfere with or collide with the upper tailgate when rotating to open and close; and the movable portion 2 can also rotate relative to the first mounting portion 1, so that the lower tailgate can rotate to open and close.

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

[0059] When the upper tailgate is in the closed state, the opening process of the lower tailgate is as follows: the movable part 2 drives the lower tailgate to move away from the upper tailgate in the first direction X until the lower tailgate does not interfere with the upper tailgate when rotating to open and close. At this time, the movable part 2 rotates relative to the first mounting part 1, thereby driving the lower tailgate to rotate and open, so as to realize the opening of the lower tailgate.

[0060] When the upper tailgate is in the closed state, the closing process of the lower tailgate is as follows: the movable portion 2 rotates relative to the first mounting portion 1, thereby driving the lower tailgate to rotate and close, and the movable portion 2 drives the lower tailgate to move in the first direction X toward the upper tailgate until the lower tailgate and the upper tailgate are closed.

[0061] It is understandable that when the upper tailgate is in the open state, the opening and closing of the lower tailgate is also the same as the above embodiment; therefore, there is no need to adjust the upper tailgate when the lower tailgate is opened and closed.

[0062] In some embodiments of the present application, the connection structure also includes a driving part 3, which is connected to the movable part 2, and the driving part 3 is configured to drive the movable part 2 to move in the first direction X and drive the movable part 2 to rotate; that is, the driving part 3 drives the movable part 2 to move, thereby realizing the opening and closing of the lower tailgate.

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

[0064] It should be supplemented that the movable part 2 can rotate relative to the first installation part 1. The movable part 2 can rotate relative to the first installation part 1 partially or as a whole, and there is no limitation here.

[0065] In some embodiments of the present application, the movable portion 2 includes a first sub-portion 21 and a second sub-portion 22, the first sub-portion 21 is connected to the first mounting portion 1 and can move along the first direction X, the second sub-portion 22 is connected to the second mounting portion and can rotate relative to the first sub-portion 21, and the second sub-portion 22 is configured to be connected to the tailgate; wherein, the movement of the first sub-portion 21 along the first direction X can drive the lower tailgate to move closer to or away from the upper tailgate in the first direction X, that is, the lower tailgate will not collide with the upper tailgate before opening, and the second sub-portion 22 can rotate relative to the first sub-portion 21, so that the lower tailgate can be rotated to open and close; in summary, the design of the first sub-portion 21 and the second sub-portion 22 makes it unnecessary for the opening and closing operation of the lower tailgate to be coordinated with the opening and closing operation of the upper tailgate.

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

[0067] When the upper tailgate is in the closed state, the closing process of the lower tailgate is as follows: the second sub-portion 22 rotates relative to the first sub-portion 21, thereby driving the lower tailgate to rotate and close, and the first sub-portion 21 drives the lower tailgate to move in the first direction X toward the upper tailgate until the lower tailgate and the upper tailgate are closed.

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

[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 one 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; this is not limited here. The relative position relationship between the first sub-portion 21 and the first mounting portion 1 can be adjusted and designed according to different vehicle models, ensuring that 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-section 22 can be arranged at any position of the first sub-section 21. For example, in one embodiment of the present application, the second sub-section 22 can be arranged inside the first sub-section 21; in another embodiment of the present application, the second sub-section 22 can be arranged on the outer surface of the first sub-section 21; there is no limitation here. The relative position relationship between the first sub-section 21 and the second sub-section 22 can be adjusted and designed according to different vehicle models, ensuring that the first sub-section 21 is connected to the second sub-section 22 and the second sub-section 22 can rotate relative to the first sub-section 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 in the first direction X and the rotation of the second sub-portion 22; it can also 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 in the first direction X and the rotation of the second sub-portion 22; for example, in one embodiment, the driving portion 3 is connected to the second sub-portion 22, and the first sub-portion 21 is driven to move in the first direction X through the second sub-portion 22, and the driving portion 3 can limit the rotation of the second sub-portion 22 or release the rotation restriction on 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, and the first sub-portion 21 is driven to move in the first direction X by the second sub-portion 22, so as to realize the movement of the lower tailgate in the first direction X away from or close to the upper tailgate.

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

[0074] Similarly, when the lower tailgate is closing, when the lower tailgate moves in the first direction X close to the upper tailgate, the second sub-portion 22 can simultaneously rotate to drive the lower tailgate to rotate and close; alternatively, after the second sub-portion 22 rotates to drive the lower tailgate to rotate and close, the lower tailgate is driven to move in the first direction X close to the upper tailgate.

[0075] See also Figure 1 to Figure 2 , Figure 1 to Figure 2 It is a structural schematic diagram of the connection structure when the lower tailgate is in a closed state.

[0076] See also Figure 3 to Figure 4 , Figure 3 to Figure 4 It is a structural schematic diagram of the connection structure when the lower tailgate is in the open state.

[0077] That is, when the lower tailgate is opened, the second sub-section 22 is driven to rotate after the first sub-section 21 finishes moving along the first direction X; when the lower tailgate is closed, the second sub-section 22 rotates first, and the first sub-section 21 moves along the first direction X again.

[0078] See also Figure 5 In some embodiments of the present application, the driving portion 3 is rotationally connected to the second sub-portion 22, the driving portion 3 and the second sub-portion 22 have a first rotating axis 4, the second sub-portion 22 and the first sub-portion 21 have a second rotating axis 5, and the first rotating axis 4 and the second rotating axis 5 are not located on the same axis; such an arrangement enables the second sub-portion 22 to rotate when the driving portion 3 rotates around the second rotating axis 5 or the first sub-portion 21 rotates around the first rotating axis 4, thereby driving the lower tailgate to rotate and open and close.

[0079] In some embodiments of the present application, a third connecting member 14 is provided on the second sub-portion 22 , and the third connecting member 14 is rotatably connected to the driving portion 3 .

[0080] In some embodiments of the present application, a fourth connecting member 15 is disposed on the second sub-portion 22 , and the fourth connecting member 15 is rotatably connected to the first sub-portion 21 .

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

[0082] In some embodiments of the present application, the connection structure also includes a first guide member 6, which is arranged on the first mounting portion 1 and extends along the first direction X, and one end of the first sub-portion 21 is movably connected to the first guide member 6 and can move in the extension direction of the first guide member 6; that is, in this embodiment, the first sub-portion 21 cooperates with the first guide member 6 so that the first sub-portion 21 can move relative to the first mounting portion 1 in the first direction X, so that the lower tailgate is close to or away from the upper tailgate in the first direction X.

[0083] The first guide member 6 can be a guide rail or a guide groove, but there is no limitation here.

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

[0085] In some embodiments of the present application, when the first sub-portion 21 moves along the extension direction of the first guide member 6, the second sub-portion 22 is relatively fixed to the first sub-portion 21; that is, in this embodiment, when the lower tailgate approaches or moves away from the upper tailgate in the first direction X, the driving unit 3 limits the rotation of the first sub-portion 21 and the second sub-portion 22 to avoid the lower tailgate from rotating simultaneously when it moves in the first direction X, thereby interfering with the upper tailgate.

[0086] In some embodiments of the present application, the connection structure also includes a second guide member 7, which is arranged on the first mounting portion 1 and connected to the first guide member 6, the extension direction of the second guide member 7 intersects with the first direction X, and one end of the first sub-portion 21 is also movably connected to the second guide member 7 and can move in the extension direction of the second guide member 7; 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 providing the second guide member 7 and the first sub-portion 21, that is, the first sub-portion 21 moves relative to the first mounting portion 1 in the first direction X and will also move along the extension direction of the second guide member 7, at this time, the driving portion 3 limits the movement of the second sub-portion 22 in the first direction X or drives the second sub-portion 22 to continue to move in the first direction X, thereby driving the second sub-portion 22 to rotate, and then realizing the rotation opening and closing of the lower tailgate.

[0087] The second guide member 7 can be a guide rail or a guide groove; there is no limitation here.

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

[0089] It can be understood that the first sub-portion 21 moves along the second guide member 7 , that is, the first sub-portion 21 rotates around the first rotation axis 4 , and the second sub-portion 22 rotates, thereby driving the lower tailgate to rotate and open and close.

[0090] In some embodiments of the present application, the driving portion 3 is arranged on the first mounting portion 1 and can move in the first direction X; that is, in this embodiment, the driving portion 3 is installed on the first mounting portion 1 and moves along the first direction X, thereby driving the first sub-portion 21 to move in the first direction X through the second sub-portion 22, so that the lower tailgate is close to or away from the upper tailgate in the first direction X.

[0091] In some embodiments of the present application, the driving portion 3 is rotatably connected to the second sub-portion 22; that is, in this embodiment, when the driving portion 3 drives the first sub-portion 21 to move in the first direction X through the second sub-portion 22, the first rotating axis 4 between the driving portion 3 and the second sub-portion 22 and the second rotating axis 5 between the second sub-portion 22 and the first sub-portion 21 are relatively arranged in the first direction X, so that the driving portion 3 can drive the first sub-portion 21 to move in the first direction X through the second sub-portion 22.

[0092] In some embodiments of the present application, when the first sub-portion 21 moves along the extension direction of the second guide member 7 , the driving portion 3 still drives the second sub-portion 22 to move in the first direction X, thereby accelerating the rotation speed of the second sub-portion 22 .

[0093] In some embodiments of the present application, the connection structure also includes a guide rod 8, which is connected to the first mounting portion 1 and extends along the first direction X; the driving portion 3 is disposed on the guide rod 8 and can move along the guide rod 8 in the first direction X; that is, in this embodiment, the guide rod 8 is provided to ensure that the movement of the driving portion 3 in the first direction X will not be offset, the driving portion 3 moves along the guide rod 8 to drive the first sub-portion 21 to move along the first direction X, and can drive the second sub-portion 22 to rotate.

[0094] In some embodiments of the present application, a through hole is provided on the driving part 3 , and the guide rod 8 passes through the through hole on the driving part 3 , so that the driving part 3 can be sleeved on the guide rod 8 and move along the first direction X.

[0095] In some embodiments of the present application, the connection structure also includes a connection portion 9, which is rotatably disposed on the vehicle body and is rotatably connected to the driving portion 3; that is, in this embodiment, the driving portion 3 is driven to move in the first direction X by the rotation of the connection portion 9.

[0096] It is understandable that, since the driving part 3 performs linear motion and the connecting part 9 performs rotational motion, the relative angle between the driving part 3 and the connecting part 9 will change during the rotation of the connecting part 9, so a rotational connection between the driving part 3 and the connecting part 9 is provided.

[0097] In some embodiments of the present application, the connecting structure includes a second mounting portion 10 and a first connecting member 11, the second mounting portion 10 is mounted on the vehicle body, and a mounting groove 13 is provided on the second mounting portion 10; one end of the first connecting member 11 is located in the mounting groove 13, and the other end is connected to the connecting portion 9; wherein the first connecting member 11 can rotate in the mounting groove 13 together with the connecting portion 9; when the driving portion 3 moves along the first direction X, the connecting portion 9 can drive the first connecting member 11 to slide in the extension direction of the mounting groove 13; that is, in this embodiment, the connecting portion 9 is fixed to the vehicle body by the cooperation between the second mounting portion 10 and the first connecting member 11, and at the same time, when the connecting portion 9 rotates, the groove wall of the mounting groove 13 will not interfere with the rotation of the connecting portion 9.

[0098] It can be understood that if the first connecting member 11 cannot slide in the installation groove 13, that is, the vertical distance from the first connecting member 11 to the guide rod 8 remains fixed, and the driving part 3 is located on the guide rod 8, then the connecting part 9, the driving part 3 and the guide rod 8 are relatively fixed, and the connecting part 9 cannot rotate.

[0099] In some embodiments of the present application, one end of the connecting portion 9 is rotatably connected to the driving portion 3; the connecting structure also includes a second connecting member 12, which is connected to the other end of the connecting portion 9 away from the driving portion 3 and is configured to connect to a driving device; wherein the first connecting member 11 is located between the second connecting member 12 and the driving portion 3; that is, in this embodiment, the driving device drives the second connecting member 12 to move, so that the connecting portion 9 can rotate around the first connecting member 11, thereby driving the driving portion 3 to move on the guide rod 8, thereby realizing the movement and rotational opening and closing of the lower tailgate in the first direction X.
