It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than that illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally a category and do not limit the number of objects, for example, the first object can be one or more. In addition, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / ", generally indicates that the front and rear associated objects are in a "or" relationship.

[0032] The tail door of the heaven and earth door has the advantages of facilitating the taking and placing of objects, saving space, and being used as a leisure platform, and is used on many vehicles. However, the upper tail door and the lower tail door usually need to be designed through complex control engineering to realize the opening and closing function, resulting in low opening and closing efficiency.

[0033] The hinge mechanism, the door system and the vehicle provided by the embodiments of the present application will be described in detail below in combination with the drawings, through specific embodiments and application scenarios.

[0034] Referring to Figures 1 to 5 The embodiments of the present application provide a hinge mechanism, comprising a first component 10 and a second component 20 connected movably, the first component 10 is fixedly connected to a vehicle body, and the second component 20 is fixedly connected to a door 30; wherein the second component 20 can slide and rotate relative to the first component 10 to drive the door 30 to switch between a closed state and an open state.

[0035] In the embodiments of the present application, the first component 10 is provided to provide support for the sliding component. Specifically, the first component 10 is fixedly connected to the vehicle body, and the second component 20 is connected to the door 30 (the door 30 can be a lower tail door, and the lower tail door will be taken as an example in the following description), in the case that the second component 20 slides and rotates relative to the first component 10, the lower tail door also moves with the sliding and rotating of the second component 20, thereby realizing the switching of the lower tail door between the closed state and the open state.

[0036] In the embodiment of the present application, the first assembly 10 and the second assembly 20 are cooperatively arranged, so that the lower tail door can slide and rotate, thereby achieving the closing and opening functions of the lower tail door. The movement trajectory of the second assembly 20 is controlled to replace the complex control engineering design, reduce the actual probability caused by the driving logic, and improve the opening and closing efficiency of the lower tail door.

[0037] Further, since the lower tail door can slide and rotate under the driving of the hinge mechanism, instead of having a single movement trajectory, the mutual interference problem between the lower tail door and the corresponding upper tail door is overcome. Therefore, when the lower tail door needs to be opened or closed, the movement and opening sequence between the lower tail door and the upper tail door no longer needs to be considered due to the interference problem, which simplifies the length of the opening and closing process of the lower tail door and further improves the opening and closing efficiency of the lower tail door.

[0038] Optionally, in the embodiment of the present application, the first assembly 10 includes a coaming 11, the coaming 11 is provided with a sliding groove 111, and the second assembly 20 is movably connected to the sliding groove 111.

[0039] In the embodiment of the present application, the coaming 11 is arranged to provide support for the sliding groove 111, and the sliding groove 111 is arranged to provide a sliding path for the second assembly 20. The second assembly 20 moves along the sliding groove 111 to drive the lower tail door to switch between the closed state and the open state. Specifically, when the second assembly 20 slides along the sliding groove 111, the lower tail door moves linearly with the sliding of the second assembly 20. When the second assembly 20 rotates along the sliding groove 111, the lower tail door rotates with the rotation of the second assembly 20. In the embodiment of the present application, the second assembly 20 and the sliding groove 111 are cooperatively arranged to slide and rotate, thereby achieving the closing and opening functions of the lower tail door. The actual probability caused by the driving logic is reduced, and the opening and closing efficiency of the lower tail door is improved.

[0040] Optionally, in the embodiment of the present application, the sliding groove 111 includes a straight portion 1111 and a curved portion 1112, and the straight portion 1111 and the curved portion 1112 are through. When part of the second assembly 20 moves along the straight portion 1111, the door slides. When part of the second assembly 20 moves along the curved portion 1112, the door 30 is flipped.

[0041] In the embodiment of the present application, the straight portion 1111 is arranged to cooperate with the second assembly 20 to drive the linear motion of the lower tail door, and the curved portion 1112 is arranged to cooperate with the second assembly 20 to drive the flipping motion of the lower tail door. The lower tail door realizes the closing and opening functions through the combination of linear motion and rotational motion.

[0042] Further, when the lower tail door is in the closed state and is opened, the second assembly 20 slides from the end of the straight portion 1111 away from the curved portion 1112 to the curved portion 1112. The second assembly 20 first slides in the straight portion 1111, so that the lower tail door moves linearly along the extension direction of the slide rail, at this time, the lower tail door has begun to open, when the second assembly 20 moves from the straight portion 1111 to the curved portion 1112, the lower tail door begins to overturn, until part of the second assembly 20 moves to the end of the curved portion 1112, the lower tail door overturns completely and is fully opened.

[0043] Further, when the lower tail door is in the closed state and is opened, the second assembly 20 slides from the end of the straight portion 1111 away from the curved portion 1112 to the curved portion 1112. The second assembly 20 first slides in the straight portion 1111, so that the lower tail door moves linearly along the extension direction of the slide rail, at this time, the lower tail door has begun to open, when the second assembly 20 moves from the straight portion 1111 to the curved portion 1112, the lower tail door begins to overturn, until part of the second assembly 20 moves to the end of the curved portion 1112, the lower tail door overturns completely and is fully opened.

[0046] In the embodiment of the present application, the guide rail 12 is arranged to limit the second assembly 20, in actual application, when the second assembly 20 moves along the straight portion 1111, the second assembly 20 has the risk of being separated from the straight portion 1111 and deviating in the movement process, which affects the opening and closing of the lower tail door. Further, the guide rail 12 is arranged on the side of the coaming 11 close to the second assembly 20, part of the guide rail 12 is oppositely arranged with the straight portion 1111, the projection of the guide rail 12 on the coaming 11 and the edge of the coaming 11 forming the straight portion 1111 coincide, it can be understood that the space for clamping the second assembly 20 formed by the guide rail 12 and the straight portion 1111 are correspondingly arranged, and the guide rail 12 is further slidingly connected with part of the second assembly 20, it can be understood that the guide rail 12 can limit the second assembly 20 moving in the slide groove 11, which has the beneficial effect of avoiding the above risks.

[0047] Further, the guide rail 12 is arranged to limit the movement of the second assembly 20 along the straight section 1111, so as to avoid the second assembly 20 connected to the guide rail 12 moving towards the curved section 1112.

[0048] Optionally, in the embodiment of the present application, the length of the guide rail 12 is greater than the length of the straight section 1111.

Specifically, the sliding member 21 and the transmission member 22 are movably connected, and the sliding member 21 is connected to a driving member, which can drive the sliding member 21 to move, and the sliding member 21 drives the transmission member 22 to move, and the transmission member 22 is connected to the tail door, thereby realizing the switching of the tail door between the closed state and the open state.

[0052] Optionally, in the embodiment of the present application, the transmission member 22 is provided with a mounting hole 221, and the sliding member 21 is arranged to pass through the mounting hole 221 and movably connected to the transmission member 22; during the sliding of the sliding member 21 and the transmission member 22 along the sliding groove 111, the transmission member 22 can rotate relative to the sliding member 21.

[0054] Optionally, in the embodiment of the present application, the sliding member 21 comprises a sliding block 211 and a first ball 212, the sliding block 211 and the first ball 212 are fixedly connected, the first ball 212 is slidably connected to the straight section 1111, and the sliding block 211 is movably connected to the guide rail 12.

[0055] Further, the transmission member 22 comprises a connecting rod 222 and a second ball 223, the second ball 223 is arranged at the end of the connecting rod 222 away from the door 30, and the second ball 223 is slidingly connected to the sliding groove 111.

[0056] In the embodiment of the present application, when the lower tail door is in the closed state and is opened, the sliding block 211 is driven to slide on the guide rail 12 by the driving member, the connecting rod 222 is driven to slide in the sliding groove 111, so that the lower tail door moves linearly along the extension direction of the linear portion 1111, when the second ball 223 moves to the curved portion 1112, the sliding block 211 still slides obliquely downward along the guide rail 12, the connecting rod 222 is driven to move, the second ball 223 rolls in the circular arc sliding groove 111, the lower tail door starts to rotate, until the second ball 223 moves to the far end of the circular arc of the sliding groove 111, the lower tail door is completely opened.

[0057] Further, when the lower tail door is in the opened state and is closed, the sliding block 211 is driven to move obliquely upward along the guide rail 12 by the driving member, the connecting rod 222 is driven to move, the second ball 223 rolls from the far end of the circular arc of the sliding groove 111 to the near end of the circular arc, so that the lower tail door rotates by 90°, and then moves obliquely upward along the extension direction of the linear portion 1111, until the second ball 223 moves to the top of the sliding groove 111, the lower tail door is completely closed.

[0058] It should be noted that, in the process of switching between the opened state and the closed state, under the limitation of the guide rail 12, the first ball 212 always only slides along the linear portion 1111 and never enters the curved portion 1112.
