[0046] Reference below Figures 1 - 6 A vehicle 100 and a hinge assembly 10 according to an embodiment of the present invention are described.

[0047] like Figure 2 、 Figure 4 and Figure 6 As shown, a vehicle 100 according to an embodiment of the present invention includes a hinge assembly 10, a vehicle body 20, and a first door body 30. The vehicle body 20 and the first door body 30 are connected by the hinge assembly 10. The first door body 30 is located on one of the left and right sides of the vehicle body 20. It will be understood that the vehicle 100 has two first door bodies 30, symmetrically arranged on the left and right sides of the vehicle body 20. When the first door body 30 is a gull-wing door, the upper end of the first door body 30 is connected to the vehicle body 20 by the hinge assembly 10. When the first door body 30 is opened, the lower end of the first door body 30 rotates upward. The vehicle 100 may also include a second door body. When the first door body 30 and the second door body are closed, the second door body may be located below the first door body 30. The second door body may be a conventional swing door that rotates along a vertical axis of rotation, or a sliding door.

[0048] In the related art, when the gull-wing door is opened, it rotates directly upward, causing the lower end of the gull-wing door to interfere with the structure below the gull-wing door. For example, when a side sliding door is installed below the gull-wing door, that is, a gull-wing door and side sliding door combination, the upper end of the side sliding door is frameless window glass. To achieve a seal between the gull-wing door and the glass, the lower end of the gull-wing door has a sealing strip with a sealing groove. The upper end of the frameless window glass at the upper end of the side sliding door is located in the sealing groove. Because part of the sealing strip is located on the inner side of the glass, interference occurs between the sealing strip and the glass when the gull-wing door is directly rotated to open. The window must be lowered before the interference is eliminated before the door can be smoothly rotated to open, which reduces the continuity and user experience of the gull-wing door opening and closing process.

[0049] like Figure 1 and Figure 2 As shown, the hinge assembly 10 according to the embodiment of the present invention includes a push rod assembly and a driving rod 3 .

[0050] Specifically, the push rod assembly (including the swing rod 1 and the push rod 2 described below) is adapted to be rotatably connected to the vehicle body 20 and the first door body 30. The two ends in the length direction of the drive rod 3 are respectively a fifth end 31 and a sixth end 32. The drive rod 3 can be telescopic and its length is adjustable. The fifth end 31 is used to be rotatably connected to the first door body 30, and the sixth end 32 is rotatably connected to the push rod assembly. For example, as Figure 1 and Figure 2 shown, the fifth end 31 has a rotation hole, and the first door body 30 has a rotation shaft that cooperates with the rotation hole of the fifth end 31. The sixth end 32 is provided with a rotation hole, and the push rod assembly is provided with a rotation shaft that cooperates with the rotation hole of the sixth end 32.

[0051] As Figure 3 shown, the first door body 30 is a gull-wing door. During the opening process of the first door body 30, the drive rod 3 starts to extend. The first door body 30 has a first stage and a second stage in sequence. In the first stage, the first door body 30 moves upward. In the second stage, the first door body 30 rotates upward and outward. It is possible to make the distal structure at the end far from the rotation axis of the first door body 30 move upward first during the opening process of the first door body 30, so as to avoid interference with the structures on the vehicle body 20 or the second door body. After the first door body 30 is disengaged from the interference with the vehicle body 20 or the second door body, then make the lower end of the first door body 30 rotate upward and outward, which improves the continuity of the opening process of the first door body 30 and the user experience.

[0052] Among them, the closing process of the first door body 30 is opposite to the opening process. During the closing process of the first door body 30, the drive rod 3 starts to shorten. The first door body 30 has a third stage and a fourth stage in sequence. In the third stage, the first door body 30 rotates downward and inward. In the fourth stage, the first door body 30 moves downward.

[0053] According to the hinge assembly 10 of the embodiment of the present invention, by making the first door body 30 have a first stage and a second stage in sequence during the opening process of the first door body 30, in the first stage, the first door body 30 moves upward, and in the second stage, the first door body 30 rotates upward and outward, it is possible to make the distal structure at the end far from the rotation axis of the first door body 30 move upward first during the opening process of the first door body 30, so as to avoid interference with the structures on the vehicle body 20 or the second door body. After the first door body 30 is disengaged from the interference with the vehicle body 20 or the second door body, then make the lower end of the first door body 30 rotate upward and outward, which improves the continuity of the opening process of the first door body 30 and the user experience.

[0054] In some embodiments of the present invention, in a first stage, one end of the push rod assembly connected to the first door body 30 drives the first door body 30 to move upward, and in a second stage, the drive rod 3 drives the first door body 30 to rotate about the rotation axis of the push rod assembly and the first door body 30. In the first stage of opening the first door body 30, the first door body 30 rotates about the rotation axis of the push rod assembly and the vehicle body 20, so that the first door body 30 moves upward, and in the second stage of opening the first door body 30, the first door body 30 rotates about the rotation axis of the push rod assembly and the first door body 30 as the rotation axis.

[0055] During the opening process of the first door body 30, the rotation center of the first door body 30 changes. The movement of the rotation center of the hinge assembly 10 can drive the first door body 30 to move upward in whole or in part, thereby causing the sealing strip on the first door body 30 to disengage from the second door body glass or other structures of the vehicle body 20. This ensures that when the first door body 30 is subsequently rotated to open, the first door body 30 will not interfere with the second door body glass or the vehicle body 20, allowing the first door body 30 to be freely opened without raising or lowering the second door body window glass. During the closing stage, the hinge assembly 10 will not move downward until the first door body 30 is completely lowered, and the door will be locked after returning to its original position.

[0056] In addition, in the present invention, the movement of the rotation center of the first door body 30 and the opening of the first door body 30 share a driving member (driving rod 3), and no additional power is required.

[0057] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the push rod assembly includes a swing rod 1 and a push rod 2. Specifically, the two ends of the swing rod 1 in the length direction are respectively a first end 11 and a second end 12, the first end 11 is used to be rotatably connected to the first door body 30, and the second end 12 is used to be rotatably connected to the vehicle body 20. For example, Figure 1 and Figure 2 As shown, the first end 11 may be provided with a rotation hole, the first door body 30 may be provided with a rotation shaft that cooperates with the rotation hole of the first end 11, the second end 12 may be provided with a rotation hole, and the body 20 may be provided with a rotation shaft that cooperates with the rotation hole of the second end 12. Of course, the present invention is not limited to this, and the first end 11 may also be provided with a rotation shaft, the first door body 30 may be provided with a rotation hole that cooperates with the rotation shaft of the first end 11, the second end 12 may also be provided with a rotation shaft, and the body 20 may be provided with a rotation hole that cooperates with the rotation shaft of the second end 12.

[0058] Among them, both ends of the swing rod 1 are respectively rotatably connected to the first door body 30 and the vehicle body 20. The swing rod 1 is used to connect the vehicle body 20 and the first door body 30, thereby realizing the rotational connection of the first door body 30 relative to the vehicle body 20. It can be understood that when the first door body 30 is a gull-wing door, the first end 11 of the swing rod 1 is connected to the end of the upper part of the first door body 30 close to the vehicle body 20.

[0059] Both ends in the length direction of the push rod 2 are respectively the third end 21 and the fourth end 22. The fourth end 22 is rotatably connected to the swing rod 1 and is movable along the length direction of the swing rod 1. The push rod 2 is used to be rotatably connected to the vehicle body 20, and the third end 21 is rotatably connected to the sixth end 32. It can be understood that the fourth end 22 is rotatable relative to the swing rod 1 and is movable along the length direction of the swing rod 1. The push rod 2 is also rotatably connected to the vehicle body 20. For example, as Figure 1 and Figure 2 shown, a rotation hole is provided on the push rod 2, and a rotation shaft matching the rotation hole on the push rod 2 is provided on the vehicle body 20. Of course, a rotation shaft can also be provided on the push rod 2, and a rotation hole matching the rotation shaft on the push rod 2 is provided on the vehicle body 20.

[0060] Among them, the fifth end 31 and the rotation center of the first door body 30 are located on one side of the rotation center of the first end 11 and the first door body 30 away from the end where the first door body 30 is connected to the vehicle body 20. Thus, under the gravity of the first door body 30, in the initial stage of opening, that is, in the first stage, the driving rod 3 will first push the push rod 2 to move. After the push rod 2 moves to the limit position, the driving rod 3 continues to move to open the first door body 30.

[0061] As Figure 3 shown, the first door body 30 is a gull-wing door. When the first door body 30 starts to open from the closed state, the driving rod 3 starts to extend. Under the gravity of the first door body 30, the sixth end 32 of the driving rod 3 is easier to push relative to the fifth end 31 of the driving rod 3. Therefore, in the first stage of opening, the first door body 30 will not rotate clockwise. The sixth end 32 of the driving rod 3 drives the push rod 2 to rotate counterclockwise around the rotation shaft between the push rod 2 and the vehicle body 20. The fourth end 22 of the push rod 2 moves upward and to the left along the length direction of the swing rod 1, pushing the swing rod 1 to rotate clockwise around the rotation shaft between the second end 12 of the swing rod 1 and the vehicle body 20, and further making the first end 11 of the swing rod 1 move upward. After the fourth end 22 of the push rod 2 moves to the left limit position along the length direction of the swing rod 1, it is the second stage. As Figure 4 and Figure 5 shown, both the first end 11 of the swing rod 1 and the third end 21 of the push rod 2 no longer move. The fifth end 31 of the driving rod 3 starts to drive the first door body 30 to rotate clockwise, making the first door body 30 open outward and upward, as Figure 6 shown.

[0062] When the first door body 30 is from Figure 6When in the closed position, the drive rod 3 shortens. The fifth end 31 of the drive rod 3 moves first, and the sixth end 32 of the drive rod 3 remains stationary. Under the combined action of the gravity of the first door body 30 and the drive rod 3, the first door body 30 rotates counterclockwise about the rotation axis between the first end 11 of the swing rod 1 and the first door body 30. After the end of the first door body 30 away from the hinge assembly 10 contacts the vehicle body 20, the drive rod 3 continues to shorten. At this time, the fifth end 31 of the drive rod 3 cannot continue to move along the telescopic direction of the drive rod 3, and the sixth end 32 of the drive rod 3 starts to move, causing the push rod 2 to rotate clockwise. The fourth end 22 of the push rod 2 drives the swing rod 1 to rotate counterclockwise, and then the first end 11 of the swing rod 1 moves downward, and the end of the first door body 30 close to the hinge assembly 10 moves toward the vehicle body 20 until the first door body 30 is completely closed. It can be understood that the opening process and the closing process of the first door body 30 are completely opposite.

[0063] Among them, in the first stage of opening the first door body 30, the first door body 30 rotates about the rotation axis between the second end 12 of the swing rod 1 and the vehicle body 20. In the second stage of opening the first door body 30, the first door body 30 rotates about the rotation axis between the first end 11 of the swing rod 1 and the first door body 30. During the opening process of the first door body 30, the rotation center of the first door body 30 changes. The movement of the rotation center of the hinge assembly 10 can drive the whole or part of the first door body 30 to move upward, so that the sealing strip on the first door body 30 is separated from the second door body glass, ensuring that the first door body 30 will not interfere with the second door body glass or the vehicle body 20 when the first door body 30 rotates and opens subsequently, so that the first door body 30 can be freely opened without raising or lowering the second door body window glass. In the closing stage, the hinge assembly 10 will move downward only after the first door body 30 completely falls back, and the door is locked after returning to its position.

[0064] In addition, in the present utility model, the movement of the rotation center of the first door body 30 and the opening of the first door body 30 share a driving member (the drive rod 3), and no additional power needs to be added. Specifically, under the action of the gravity of the first door body 30, the drive rod 3 will first push the push rod 2 to move at the initial stage of opening. After the push rod 2 moves to the limit position, the drive rod 3 continues to move to open the first door body 30. The whole process is realized only by the drive of the drive rod 3, without an additional drive mechanism.

[0065] In addition, the hinge assembly 10 of the present application includes a swing rod 1, a push rod 2 and its driving device (the drive rod 3). The function of moving the rotation center of the first door body 30 is realized through the movement and rotation cooperation between the push rod 2 and the swing rod 1. The number of parts is small, the cost is low, and the structure is simple and reliable.

[0066] In some embodiments of the present utility model, such as Figure 1 and Figure 2As shown, the connection position between the push rod 2 and the swing rod 1 is located between the first end 11 and the second end 12. This can avoid interference between the movement of the push rod 2 and the movement of the swing rod 1. Additionally, when the push rod 2 drives the swing rod 1 to rotate, the stroke of the rotation of the push rod 2 can also be reduced, thereby reducing the volume of the entire hinge assembly 10 and the space occupied by the hinge assembly 10.

[0067] In some embodiments of the present utility model, as Figure 1 and Figure 2 shown, the rotation center of the push rod 2 and the vehicle body 20 is located between the third end 21 and the fourth end 22. It can be understood that the rotation center of the push rod 2 and the vehicle body 20 is spaced apart from both ends in the length direction of the push rod 2, and the push rod 2 is formed into a lever structure. Thus, the movement of the driving rod 3 is facilitated to be transmitted to the swing rod 1 through the push rod 2.

[0068] In some embodiments of the present utility model, as Figure 1 shown, the swing rod 1 includes a first rod 13 and a second rod 14 connected to each other. The end of the first rod 13 facing away from the second rod 14 forms the first end 11, and the end of the second rod 14 facing away from the first rod 13 forms the second end 12. The fourth end 22 is rotatably connected to the second rod 14 and is movable along the length direction of the second rod 14. The first rod 13 and the second rod 14 form an angle with each other. This can avoid interference and collision between the first door body 30 and the vehicle body 20 at the rotation axis during the opening process of the first door body 30, and improve the reliability of the opening of the first door body 30.

[0069] In some embodiments of the present utility model, the end of the first rod 13 facing away from the second rod 14 extends towards the first door body 30 and forms an angle with the first door body 30. Preferably, the first rod 13 is perpendicularly arranged with respect to the first door body 30. In the second stage, a part of the first rod 13 extends out of the vehicle body 20.
