Hinge and vehicle

[0001] This application claims priority to Chinese patent application number 202311531617.1, filed on November 15, 2023, entitled “A Hinge and Vehicle,” the entire contents of which are incorporated herein by reference. Technical Field

[0002] The present application relates to the field of automobile technology, and more particularly to a hinge and a vehicle. Background Art

[0003] Car door opening methods are becoming increasingly diverse, with the rotary wing type being one of the newest and most popular.

[0103] As shown in Figure 4, in a specific embodiment, the axis of the third mounting shaft 104 is the third axis 131, and the first connecting rod 102 rotates relative to the second mounting portion 109 with the third axis 131 as the axis; the axis connecting the driving member 105 and the intermediate rod 106 is the fourth axis 132, and the driving member 105 and the intermediate rod 106 both rotate relative to each other with the fourth axis 132 as the axis; the axis of the through hole of the follower 108 corresponding to the second mounting portion 109 is the fifth axis 133, and the follower 108 rotates relative to the second mounting portion 109 with the second axis 137 as the axis; the line between the first lug 1081 and the second lug 1082 of the follower 108 is the sixth axis 134, and the intermediate rod 106 and the follower 108 both rotate relative to each other with the sixth axis 134 as the axis.

One end of the driven member 108 of the rotating mechanism passes through the through-hole and is rotatably connected to the third mounting portion, allowing the third mounting portion to rotate under the influence of the rotating mechanism. Mounting structures are provided at the three corners of the third mounting portion. Through these structures, the third mounting portion is fixedly connected to the vehicle door 200 by bolts, preventing the vehicle door 200 from rotating relative to the third mounting portion, thereby allowing the vehicle door 200 to rotate synchronously with the third mounting portion.

Therefore, it drives the second mounting portion 109 and the connecting rod mechanism to rotate accordingly, realizing the combined movement of the vehicle door 200 in the X and Y directions.

[0114] The present application also provides a vehicle, comprising a vehicle body, a vehicle door 200 and a hinge 100 according to any one of claims 1-16, wherein the first mounting portion 101 is connected to the vehicle body, the output end of the rotating mechanism is connected to the third mounting portion, and the third mounting portion is connected to the vehicle door 200.

[0115] As shown in Figures 12 and 13, in a specific embodiment, a hinge 100 is provided at the mounting frame of the vehicle door 200, the first mounting portion 101 is fixedly connected to the vehicle body by bolts, the third mounting portion is fixedly connected to the vehicle door 200 by bolts, and the third mounting portion is installed at the upper end of the vehicle door 200 as much as possible to ensure that the vehicle door 200 is not lifted too high during the opening process.

[0116] As shown in Figures 5 and 11, the second connecting rod always follows the first connecting rod 102 in rotating at a constant speed and radius, but the rotational motion of the first connecting rod 102 and the driving member 105 is not constant speed. The angle between the centerline 151 of the first connecting rod and the centerline 151' of the first connecting rod after the door is opened is the swing arm door opening angle 143, and the angle between the first axis 136 and the sixth axis 134 is the first crank angle 141. When the vehicle door 200 is opened 90°, the first crank angle 141 increases by 90°, and the swing arm door opening angle 143 is greater than 0° and less than 90°. The first crank angle 141 and the swing arm door opening angle 143 change speed during the opening process, and have a quick return characteristic.

[0117] Furthermore, as shown in FIG9 , the angle between the first axis 136 and the fourth axis 132 is a second crank angle 142 , which remains unchanged during the opening and closing process of the vehicle door 200 . The size of the second crank angle 142 can change the swing arm door opening angle 143 .

[0118] Furthermore, as shown in Figures 8, 11, 12 and 13, during the opening process of the car door 200, the electric strut or hydraulic strut will drive the third mounting part to which it is connected, driving the car door 200 to rotate while driving the first connecting rod 102 and the second connecting rod 103 to rotate around the first axis 136 and the second axis 137 respectively. The rotation angles are both the swing arm door opening angle 143. The center line 151 of the first connecting rod rotates to the center line 151' of the first connecting rod after the door is opened. The follower 108 drives the third mounting part and the car door 200 to rotate 90 degrees in the Y direction (i.e. outside the car) and the Z direction (i.e. downward) to open in a compound manner, finally reaching the open state of the car door 200 as shown in Figures 11 and 13.

[0119] During the closing process of the vehicle door 200, the electric support rod or the hydraulic support rod retracts, which will drive the third mounting part to rotate in the opposite direction. Since the third mounting part is connected to the follower 108 of the rotating mechanism, it will drive the rotating mechanism to rotate. Furthermore, the rotating mechanism is connected to the connecting rod mechanism and the second mounting part 109, and the second mounting part 109 is connected to the connecting rod mechanism, so it will drive the second mounting part 109 and the connecting rod mechanism to rotate in the opposite direction accordingly, realizing the combined closing movement of the vehicle door 200 in the X direction and the Y direction.
