[0078] like Figure 1 and Figure 2 As shown, the first aspect of the utility model discloses a hinge structure 100. The hinge structure 100 is used to connect a vehicle door 200 to a vehicle body 300, and includes a base 110, a support rod 120 and a mounting member 140. The base 110 is used to be connected to the vehicle body 300. The first end of the support rod 120 is rotatably connected to the base 110 around a first support axis B1. The second end of the support rod 120 is provided with a first gear 121 and a second gear 122 opposite to each other. The first gear 121 is fixedly connected to the second end of the support rod 120, and the second gear 122 is rotatably connected to the second end of the support rod 120. The mounting member 140 includes a mounting portion 141. The mounting portion 141 can rotate around the rotation axis A1. The mounting portion 141 is used to be connected to the vehicle door 200. The mounting portion 141 has a third gear 143, and the third gear 143 is meshed with the first gear 121 and the second gear 122.

[0079] According to the utility model, a second gear 122 meshing with the third gear 143 is additionally provided, which plays a role of auxiliary support. The meshing state of the third gear 143 is greatly improved under the dual support of the first gear 121 and the second gear 122, ensuring that the third gear 143 will not be laterally deflected due to lateral loads, making its meshing more stable, reducing vibration and noise during movement, and increasing its service life.

[0080] In one embodiment of the present invention, the first gear 121, the second gear 122 and the third gear 143 are all bevel gears, so that the meshing between the gears is tighter and the matching movement is smoother.

[0081] Specifically, the mounting portion 141 has a mounting seat 142 , and the mounting seat 142 is used to be connected to the vehicle door 200 .

[0082] Further, the hinge structure 100 further includes a guide rod 130. A first end of the guide rod 130 is rotatably connected to the base 110 around a first guide axis C1. The guide rod 130 is rotatable relative to the base 110 between a folded position and an unfolded position.

[0083] The mounting member 140 further includes a connecting portion 144. The connecting portion 144 is rotatably connected to the support rod 120 around the second support axis B2, and is rotatably connected to the second end of the guide rod 130 around the second guide axis C2. The mounting portion 141 is rotatably connected to the connecting portion 144 around the rotation axis A1. The base 110, the support rod 120, the guide rod 130, and the mounting member 140 are configured as a four-bar linkage.

[0084] Further, the four-bar linkage can be constructed as a parallelogram four-bar linkage, that is, the base 110 is arranged in parallel with the mounting portion 141. The rotation axis A1 is perpendicular to the first support axis B1. In other words, during the movement of the hinge structure 100, the mounting portion 141 remains parallel to the base 110, and the guide rod 130 and the support rod 120 have the same rotation speed and direction, so that the hinge structure 100 does not have a snap-back characteristic and the movement process is smoother. In this embodiment, the mounting portion 141 is not rotatable relative to the connecting portion 144 around an axis parallel to the second support axis B2, so the mounting member 140 as a whole constitutes part of the four-bar linkage. Due to the characteristics of the four-bar linkage and the base 110 is fixed, the mounting member 140 including the mounting portion 141 and the connecting portion 144 remains parallel between any two positions during the movement. Therefore, the vehicle door 200 connected to the mounting portion 141 always remains parallel during the opening or closing process.

[0085] like Figure 1 and Figure 2 As shown, during the movement of the four-bar linkage, the mounting portion 141 rotates relative to the support rod 120, so that the third gear 143 rotates around the rotation axis A1 under the meshing action with the first gear 121, completing the rotation opening or closing of the door 200. The rotation of the four-bar linkage is synchronized with the rotation of the mounting portion 141 around the rotation axis A1, so that the door 200 moves in a lateral direction while performing a rotational movement. Since the third gear 143 is meshed with the second gear 122, when the third gear 143 rotates around the rotation axis A1, the second gear 122 also rotates to play a stabilizing role. The second gear 122 can rotate around the second support axis B2.

[0086] The transmission ratio of the first gear 121 to the third gear 143 is 1:0.8-1:1.2. The rotation angle of the support rod 120 around the first support axis B1 is linearly related to the rotation angle of the mounting portion 141 around the rotation axis A1, and the movement process is stable. The transmission ratio of the first gear 121 to the third gear 143 is preferably 1:1. In this case, the rotation angle of the support rod 120 is equal to the rotation angle of the mounting portion 141. For example, Figure 3 and Figure 4 As shown, the rotation angle β of the support rod 120 around the first support axis B1 is 90°, and the mounting portion 141 also rotates 90° around the rotation axis A1. The third gear 143, the first gear 121 and the second gear 122 have the same size, thereby forming a more stable structure.

[0087] like Figure 5 As shown, a boss 123 is provided on the side of the second gear 122 facing away from the first gear 121. When the movement stroke of the support rod 120 changes and the structure of the third gear 143 and the first gear 121 needs to be adjusted to change the transmission ratio and the gear center distance, the second gear 122 with different boss 123 thicknesses can be replaced to facilitate and simply match the second gear 122 with the third gear 143, thereby saving costs without replacing the entire hinge structure 100.

[0088] like Figure 2 As shown, the hinge structure 100 includes a driving rod 150. The driving rod 150 is used to be connected to the vehicle body 300 and the supporting rod 120 respectively to drive the supporting rod 120 to move.

[0089] Preferably, the connection point of the driving rod 150 for connecting to the vehicle body 300 and the connection point of the base 110 for connecting to the vehicle body 300 are spaced apart along the plane where the base 110 is located. In other words, in the open state of the hinge structure 100, the distance from the connection point of the driving rod 150 and the vehicle body 300 to the mounting portion 141 in the horizontal direction is greater than the distance from the connection point of the base 110 and the vehicle body 300 to the mounting portion 141, that is, the connection point of the driving rod 150 and the vehicle body 300 is closer to the interior of the vehicle than the connection point of the base 110 and the vehicle body 300. In this way, the driving rod 150 has a longer stroke, so that the door can be opened to a larger degree.

[0090] In one embodiment of the present invention, one end of the driving rod 150 that is adapted to be connected to the vehicle body 300 is located above the base 110 .

[0091] When the guide rod 130 is located at the folded position, the angle between the connecting portion 144 and the guide rod 130 is greater than 35°, so that the four-bar linkage can be more easily driven by the driving rod 150 to move.

[0092] Further, the driving rod 150 includes a driving main rod 151 and a driving sub-rod 152 to drive the four-bar linkage to move. The driving main rod 151 is used to be rotatably connected to the vehicle body 300 around the first driving axis D1. The driving sub-rod 152 is rotatably connected to the support rod 120 around the second driving axis D2 and is slidably disposed on the driving main rod 151. The driving main rod 151 and the driving sub-rod 152 can be configured as an electric telescopic rod or a hydraulic telescopic rod.

[0093] like Figure 6 As shown, the guide rod 130 and the connecting portion 144 are closer to the second gear 122 than the driving rod 150 in a direction parallel to the second support axis B2. Thus, the staggered arrangement can save space, overcome the problem of limited space for the hinge structure 100, and prevent the driving rod 150 from having structural interference with the guide rod 130 when the four-bar linkage moves.

[0094] Preferably, the connection between the driving rod 150 and the support rod 120 is located between the first end and the second end of the support rod 120. Connecting the driving rod 150 in the middle of the support rod 120 can enable the driving rod 150 to obtain a larger motion stroke, facilitate the hovering action of the four-bar linkage at any position, and have a higher control accuracy of the motion process.

[0095] like Figure 7 and Figure 8 As shown, the second aspect of the present invention discloses a vehicle door structure. The vehicle door structure comprises a vehicle door and the above-mentioned hinge structure 100 . The mounting portion 141 is connected to the vehicle door 200 .

[0096] According to the utility model, the vehicle door structure includes the above-mentioned hinge structure, so the vehicle door structure has a technical effect similar to that of the hinge structure.

[0097] The first support axis B1 extends along the length direction of the vehicle, that is, when the door structure is in a closed state, the support rod 120 extends along the height direction of the vehicle; when the door structure is in an open state, the support rod 120 extends along the width direction of the vehicle.

[0098] The third aspect of the utility model discloses a vehicle, which includes the hinge structure 100 or the door structure, wherein the base 110 is connected to the vehicle body 300 , and the mounting portion 141 is connected to the door 200 .

[0099] The mounting point where the base 110 of the hinge structure 100 is connected to the vehicle body 300 is compatible with the mounting point of the common side-opening door hinge structure, making it highly replaceable and facilitating the selection and assembly of multiple hinge structures. The mounting portion 141 of the hinge structure 100 can be connected to the lower part of the vehicle door 200, thereby increasing the range of motion of the vehicle door 200 during opening, making it easier for users to enter and exit the vehicle.

[0100] The support rod 120 of the hinge structure 100 is used to bear the weight of the vehicle door 200, so the length of the support rod 120 along the direction from the base 110 to the mounting portion 141 is greater than the thickness of the vehicle door 200, which can make the structure more stable and safe, and drive the vehicle door 200 to move more smoothly through the hinge structure 100. In addition, the size of the support rod 120 is greater than that of the guide rod 130.

[0101] When the vehicle door 200 is in the closed state, the support rod 120 of the hinge structure 100 extends substantially in the vertical direction, thereby making the setting position of the hinge structure 100 more flexible. For example, when the horizontal space of the vehicle is insufficient, the hinge structure 100 can be set in the vertical plane of the front end of the vehicle door 200. At the same time, when the vehicle door 200 is in the closed state, the mounting portion 141 is located above the base 110, so that the vehicle door 200 moves downward during the opening process, preventing the vehicle door 200 from being lifted too high after opening, thereby affecting the overall aesthetic effect of the vehicle.

[0102] like Figure 3 As shown, when the door 200 is in the closed state, the support rod 120 of the hinge structure 100 can also be tilted toward the vehicle body 300, so that the door 200 has a tendency to automatically close under the action of gravity, and the gravity of the door 200 itself is used to achieve a good and stable closing effect. Further, when the door 200 is in the closed state, the angle α between the support rod 120 and the vertical direction is 7°-13°, preferably 10°.

[0103] Unless otherwise defined, the technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art of the present invention. The terms used herein are only for describing specific implementation purposes and are not intended to limit the present invention. The features described herein in one embodiment may be applied to another embodiment alone or in combination with other features, unless the feature is not applicable or otherwise specified in the other embodiment.

[0104] The present invention has been described through the above-mentioned embodiments, but it should be understood that the above-mentioned embodiments are only for the purpose of example and explanation, and the present invention is not limited to the above-mentioned embodiments. According to the teachings of the present invention, more variations and modifications can be made, and these variations and modifications all fall within the scope of protection required by the present invention.
