[0038] This embodiment provides a vehicle body 18 in the prior art, which is generally a car body, with openings on both sides for entering the interior of the car, and the door 17 is used to open and close the opening of the car.

[0039] The door 17 is slidably disposed on the vehicle body 18 and is used to open and close the opening of the vehicle body 18 . The opening can be opened or closed by sliding along the left and right directions of the main body of the vehicle body 18 .

[0040] Swing door drive mechanism

[0041] As attached Figure 1 As shown, the swing door drive mechanism includes an active connecting rod assembly 16 and a driven connecting rod assembly 15, the upper side of the vehicle body 18 is connected to the upper side of the vehicle door 17 through the driven connecting rod assembly 15, and the lower side of the vehicle body 18 is connected to the lower side of the vehicle door 17 through the active connecting rod assembly 16. The structure of the swing door mechanism is described in detail below, and the characteristic part of the utility model is also described. In addition, for the convenience of description below, the directions of the structural elements of the upper and lower swing door mechanisms are determined in the state of being loaded on the vehicle body 18. The swing door drive mechanism is used to enable the vehicle door 17 to be slidably arranged on the vehicle body 18 along the left and right directions of the main body of the vehicle body 18.

[0042] At the same time, the active connecting rod assembly 16 is used to provide power for the movement of the vehicle door 17. The working process of the movement of the vehicle door 17 on the vehicle body 18 is as follows: the active connecting rod assembly 16 can be used as an actuator for the movement of the vehicle door 17, and is used to provide power for the rotation of the supporting connecting rod. The driven connecting rod assembly 15 can be used as a follower component for the movement of the vehicle door 17. During the movement of the vehicle door 17, the driven connecting rod assembly 15 can be driven to move, so that the force is stabilized to maintain synchronization during the movement, thereby allowing the vehicle door 17 to move smoothly on the vehicle body 18.

[0043] Active connecting rod assembly

[0044] like Figure 2-3 As shown, the active link assembly 16 includes a fixed bracket A1, which is fixedly connected to the vehicle door 17; it also includes a body bracket A2, which is fixedly connected to the vehicle body 18 of the vehicle door 17; it also includes a support link A3, both ends of which are rotatably connected to the fixed bracket A1 and the body bracket A2; it also includes a rotating link A4, one end of which is rotatably connected to the fixed bracket A1; it also includes a rotating link B5, one end of which is rotatably connected to the body bracket A2, and the other end of the rotating link B5 is rotatably connected to the other end of the rotating link A4; it also includes an electric support rod A6, which is used to drive the two ends of the rotating link A4 and the rotating link B5 that are far away from each other to move closer or farther away; it also includes a power unit 7, which has an output shaft, which is used to drive the support link to rotate; wherein, the two ends of the electric support rod A6 are respectively rotatably connected to the two ends of the rotating link A4 and the rotating link B5 that are far away from each other.

[0045] At the same time, the above-mentioned rotational connections are all rotationally connected through pins. In the active link assembly 16, the pins connecting the two ends of the rotation link A4 and the rotation link B5 that are separated from each other are parallel to the axis of the pin connected to the support link A3, and the axis of the pin connecting the fixed bracket A1 and the body bracket A2 is also parallel.

[0046] The rotating link A4, the rotating link B5 and the electric support rod A6 form a triangle, and the angle formed by the rotating link A4 and the rotating link B5 can be adjusted by extending and retracting the electric support rod A6. At the same time, the distance between the pins connecting the two ends of the rotating link A4 and the rotating link B5 that are far away from each other can be changed by adjusting the angle formed by the rotating link A4 and the rotating link B5, so that the fixed bracket A1 can be controlled to tilt or move parallel to the body bracket A2.

[0047] The vehicle body support A2 is provided with a power unit 7 for driving the supporting link A3 to rotate and providing power for the rotation of the supporting link A3.

[0048] When the active link assembly 16 is running, the power unit 7 provides rotational power to the supporting link A3, so that after the supporting link A3 is rotated and opened, it will drive the fixed bracket A1 to move, and control the fixed bracket to tilt or move parallel to the body 18 bracket by rotating the link A4, rotating the link B5 and the electric support rod B14, thereby driving the door 17 to move.

[0049] Power Unit

[0050] like Figure 2-3 As shown, the power unit 7 is a driving motor 9 having an output shaft mounted on a fixed bracket A1 of the active connecting rod assembly 16 .

[0051] At the same time, in this embodiment, a rotating shaft 8 is fixedly and rotatably arranged inside the fixed bracket A1, one end of the supporting link A3 is rotatably connected to the fixed bracket through a pin, the other end of the supporting link A3 is fixedly connected to the outer surface of the rotating shaft 8, and the pin connecting the two ends of the rotating link A4 and the rotating link B5 away from each other and the pin connected to the supporting link are parallel to the axis of the rotating shaft 8.

[0052] The driving motor 9 is installed on the fixed bracket A1, and its output shaft is fixedly connected to the rotating shaft 8, which is used to drive the rotating shaft 8 to rotate. When the rotating shaft 8 rotates, it will drive the supporting connecting rod A3 to rotate and open with the rotating column as the axis, providing power for the rotation of the supporting connecting rod A3.

[0053] Driven connecting rod assembly

[0054] like Figure 4-5As shown, the driven link assembly 15 includes a fixed bracket B10, which is fixedly connected to the vehicle door 17; it also includes a body bracket B11, which is fixedly connected to the vehicle body 18 of the vehicle door 17; it also includes a supporting link B12, both ends of which are rotatably connected to the fixed bracket B10 and the body bracket B11; it also includes a telescopic assembly for adapting the distance between the fixed bracket B10 and the body bracket B11; it also includes a supporting assembly for providing power to the supporting link B12; wherein the fixed bracket B10, the body bracket B11 and the supporting link B12 respectively move by following the fixed bracket A1, the body bracket A2 and the supporting link A3 through the vehicle door 17.

[0055] The driven link assembly 15 can serve as a follower component for the movement of the vehicle door 17 . During the movement of the vehicle door 17 , the driven link assembly 15 can be driven to move, so that the force is stabilized to maintain synchronization during the movement, thereby allowing the vehicle door 17 to move smoothly on the vehicle body 18 .

[0056] Telescopic components

[0057] As attached Figure 4-5 As shown, the telescopic assembly includes a telescopic rod 13, which is used to adapt to the distance between the fixed bracket B10 and the body bracket B11. The two ends of the telescopic rod 13 are rotatably connected to the fixed bracket B10 and the body bracket B11 respectively, and the telescopic end of the telescopic rod 13 is connected to either the fixed bracket B10 or the body bracket B11.

[0058] The fixed bracket B10, the body bracket B11, the support link B12 and the telescopic rod 13 of the driven link assembly 15 form a four-bar hinge mechanism, and an additional support assembly is installed to provide power to the support link B12. The above-mentioned rotational connections are all connected by a pin, and the axis of the pin connected to the telescopic rod 13 and the support link B12 is parallel, and the axis of the pin connected to the fixed bracket B10 and the body bracket B11 is also parallel;

[0059] When the rotating link A4, the rotating link B5 and the electric support rod A6 of the active connecting rod assembly 16 control the fixed bracket A1 to tilt or move parallel to the body bracket A2 through the telescopic control of the electric support rod A6, the door 17 will be driven to tilt or move parallel to the body 18. At this time, the door 17 will drive the fixed bracket B10 and the body bracket B11 to tilt or move parallel. The telescopic rod 13 is used to adapt the distance between the fixed bracket B10 and the body bracket B11 when the fixed bracket B10 and the body bracket B11 are tilted or moved parallel, so as to play a supporting and stabilizing effect. The length can be adjusted according to the opening and closing angle of the fixed bracket B10 and the body bracket B11, so as to make the opening and closing of the door 17 stable.

[0060] Support components

[0061] As attached Figure 4-5 As shown, the support assembly includes an electric support rod B14, which is used to provide power to the support link B12. One end of the electric support rod B14 is rotatably connected to the vehicle body bracket B11, and the other end of the electric support rod B14 is located between the two ends of the support link B12 and is rotatably connected to the support link B12. The telescopic end of the electric support rod A6 is rotatably connected to either the support link B12 or the vehicle body bracket B11.

[0062] The electric support rod B14 provides auxiliary power support to help open and close the door 17. The electric support rod B14 is activated to drive the support link B12 to rotate outward on the vehicle body bracket B11 to open.

[0063] Opening and closing of door 17

[0064] When the vehicle door 17 needs to be opened, the vehicle body 18 also has a ceiling lock and a ground lock (not shown in the figure), and the vehicle door 17 has a matching surface (not shown in the figure) for matching with the ceiling lock and the ground lock, which is used to lock the vehicle door 17 (all of which are commercially available products, and the principle is the existing technology, which will not be described in detail here). First, the locking of the vehicle door 17 by the ceiling lock and the ground lock is released, and then the electric support rod A6 is retracted to reduce the distance between the farthest ends of the rotating link A4 and the rotating link B5, so that the fixed bracket A1 is tilted to the vehicle body bracket A2, driving the vehicle door 17 to tilt to the vehicle body 18, and driving the fixed bracket B10 to tilt to the vehicle body bracket B11 through the vehicle door 17. At this time, the telescopic rod 13 is retracted and adapted, so that the matching surface of the vehicle door 17 is disengaged from the ceiling lock;

[0065] Then start the electric support rod B14 and the driving motor 9. The driving motor 9 drives the supporting link A3 to rotate and open. When the supporting link A3 rotates and opens, the supporting link B12 also needs to move synchronously. At this time, the electric support rod B14 plays an auxiliary role.

[0066] At the same time, the electric support rod A6 is started to reset, driving the distance between the farthest ends of the rotating link A4 and the rotating link B5 to reset, so that the fixed bracket A1 is parallel to the body bracket A2, driving the door 17 to be parallel to the body 18, thereby driving the fixed bracket B10 to be parallel to the body bracket B11, and the telescopic rod 13 is adapted to follow and opened with the rotation of the support link A3 and the support link B12, so that the door 17 slides outward to open the door 17, and the opposite is true if it needs to be closed.

[0067] The outside of the vehicle door 17 may be provided with a handle (not shown) for unlocking the vehicle door 17 , and when the vehicle door 17 is pulled by the handle, the swing door drive mechanism may move with the vehicle door 17 to maintain the stability of the vehicle door 17 during movement.

[0068] The embodiments of the present application are described above in conjunction with the accompanying drawings. In the absence of conflict, the embodiments in the specification of the present application and the features in the embodiments can be combined with each other. The present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
