Obviously, the embodiments described are only part of the embodiments of the present application, not 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.

The door body is connected and fixed to a connecting swing arm 40 of the hinge structure 100, and the body is connected and fixed to a mounting base 10 of the hinge structure 100.

[0040] In some embodiments, the mounting base 10 of the hinge structure 100 is connected to a side panel of a vehicle.

[0041] Please refer to Figures 1 to 2. The hinge structure 100 includes a mounting base 10, a sliding arm 20, a ball head arm 30, a connecting swing arm 40 and a first rotating arm 50. The sliding arm 20 is slidingly connected to the mounting base 10; the ball head arm 30 is rotationally connected to the sliding arm 20; the connecting swing arm 40 is rotationally connected to the end of the ball head arm 30 away from the sliding arm 20; and the first rotating arm 50 is rotationally connected to both the mounting base 10 and the connecting swing arm 40.

[0042] The sliding arm 20 is slidably connected with the mounting base 10, so that the sliding arm 20 guides the rotation of the connecting swing arm 40, and the assembly precision requirement is low relative to the spatial spherical four-bar linkage structure, and it is not necessary to ensure that the four shafts intersect at one point, and the sliding arm 20 slides on the mounting base 10, which is relative to rotation, so that the hinge structure 100 has a compact overall structure.

[0043] During the opening of the door body, the door body can realize a side opening action relative to the vehicle body, that is, the hinge structure 100 can realize a side opening door; or a combined action of first side opening and then upward rotation, that is, the hinge structure 100 can realize a scissor type door opening; or the hinge structure 100 can realize the side opening door or the scissor type door opening, which is beneficial to saving the cost of opening the mold of the vehicle body and ensuring that the door lock can be used in the opening and closing action of the side door arrangement state. The closing process of the door body is opposite to the opening action of the door body.

[0044] During the opening or closing of the door body, the connecting swing arm 40 simultaneously rotates relative to the ball head arm 30 and the mounting base 10, the connecting swing arm 40 rotates to drive one end of the sliding arm 20 to rotate through the ball head arm 30, one end of the sliding arm 20 is slidably connected with the mounting base 10, the sliding arm 20 rotates under the driving of the ball head arm 30 and converts the rotating action into a sliding action, so that the same distance from the surface of the mounting base 10 is always kept, and the hinge structure 100 has a compact overall structure.

[0045] The hinge structure 100 in the embodiment has three rotating pairs, one spherical pair and one sliding pair, and finally realizes a sliding type guiding hinge structure 100, so that the door body has a unique motion trajectory, the entire hinge structure 100 has a single degree of freedom structure and good motion stability. One end of the first rotating arm 50 forms a rotating pair at the mounting base 10, the other end of the first rotating arm 50 forms a rotating pair at the connecting swing arm 40, one end of the sliding arm 20 forms a rotating pair at the ball head arm 30, the ball head arm 30 forms a spherical pair at the connecting swing arm 40, and the other end of the sliding arm 20 forms a sliding pair at the mounting base 10.

[0046] Please refer to FIG. 3, the sliding arm 20 includes a connecting rod 21 and a rolling piece 22, one end of the connecting rod 21 is connected with the rolling piece 22, the rolling piece 22 is slidably connected with the mounting base 10, and the other end of the connecting rod 21 is rotatably connected with the ball head arm 30.

[0047] One end of the connecting rod 21 is mounted with one or more rolling elements 22, which are slidably connected to the mounting base 10. The rolling elements 22 can slide linearly or arcuately along the surface of the mounting base 10. The other end of the connecting rod 21 is rotatably connected to the ball-head arm 30. When the connecting swing arm 40 rotates relative to the ball-head arm 30, the connecting swing arm 40 drives one end of the connecting rod 21 to rotate via the ball-head arm 30. Since one end of the connecting rod 21 is slidably connected to the mounting base 10 via the rolling elements 22, the connecting rod 21, driven by the ball-head arm 30, can simultaneously rotate relative to the ball-head arm 30 and slide relative to the mounting base 10.

[0048] The rolling element 22 may be a pulley or a rolling bearing, so that the rolling element 22 drives the sliding arm 20 to slide relative to the mounting base 10 .
