[0030] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0031] Refer to Figure 2-12 A swing door assembly for an automobile as shown, comprising:

[0032] Lower swing door assembly, the lower swing door assembly includes a first mounting seat 1, a second mounting seat 2 and a fourth mounting seat 4. Among them, the first mounting seat 1 is hinged to a first connecting arm 6. An assembly hole is provided in the first mounting seat 1, and the first connecting arm 6 is rotatably connected in this assembly hole through a first rotating shaft 17. The second mounting seat 2 is hinged to a second connecting arm 7. An assembly hole is also provided in the second mounting seat 2, and the second connecting arm 7 is rotatably connected in this assembly hole through a second rotating shaft 11. The other end of the second connecting arm 7 is hinged to a third connecting arm 8. Similarly, the second connecting arm 7 is rotatably connected in the third connecting arm 8 through a third rotating shaft 12. Specifically, the third connecting arm 8 is rotatably connected to the second connecting arm 7 through a rotating shaft, a first gasket 29, a second gasket 30, a bushing 31 and a locking bolt 32. The two ends of the fourth mounting seat 4 are respectively hinged to the first connecting arm 6 and the third connecting arm 8 through a fifth rotating shaft 14 and a fourth rotating shaft 13. A driving device 9 for driving the first connecting arm 6 to rotate is further installed on the first mounting seat 1. The lower swing door assembly is fixedly connected to the vehicle body 25 through the first mounting seat 1 and the second mounting seat 2. A limiting structure is connected to the third connecting arm 8. Through this limiting structure, the swinging angle of the third connecting arm 8 can be limited, so that after the swing door assembly is connected to the car door, the trajectory of the car door can be unique;

[0033] Upper swing door assembly, the upper swing door assembly includes a third mounting seat 3 and a fifth mounting seat 5. The third mounting seat 3 is hinged to the tail of an electric telescopic rod 10 through a sixth rotating shaft 15. The top of the electric telescopic rod 10 is hinged to the fifth mounting seat 5 through a fifth rotating shaft 14. The upper swing door assembly is fixed to the vehicle body 25 through the third mounting seat 3.

[0034] The process of using the present invention is as follows. First, the lower swing door assembly and the upper swing door assembly are respectively installed on the vehicle body 25 of the car, as Figure 8As shown in the figure, the upper swing door assembly is installed on the upper part of the vehicle body 25, and the lower swing door assembly is installed on the lower part of the vehicle body 25. Specifically, the lower swing door assembly is fixed to the vehicle body 25 through the first mounting seat 1 and the second mounting seat 2, and then fixed to the lower part of the vehicle door through the fourth mounting seat 4; the upper swing door assembly is fixed to the upper part of the vehicle body 25 through the third mounting seat 3 and fixed to the upper part of the vehicle door through the fifth mounting seat 5. Among them, the vehicle door to which the upper swing door assembly and the lower swing door assembly are connected can be the front vehicle door 23 of the vehicle, or the rear vehicle door 24 of the vehicle, or the front vehicle door 23 and the rear vehicle door 24 of the vehicle can be installed simultaneously. When the lower swing door assembly and the upper swing door assembly are connected and the vehicle door is opened, the driving device 9 drives the first connecting arm 6 to rotate. Since the first connecting arm 6, the fourth mounting seat 4, the third connecting arm 8, the second connecting arm 7, and the frame formed by the first mounting seat 1 and the second mounting seat 2 together form a five-bar linkage mechanism, when the first connecting arm 6 rotates, it will drive the vehicle door to swing. At the same time, the electric telescopic rod 10 on the third mounting seat 3 also starts to extend synchronously, driving the vehicle door to swing more smoothly. Among them, Figure 10 is the relationship diagram of the telescopic length of the electric telescopic rod of the present invention and the rotation angle of the first connecting arm. After the swing assembly is installed on the vehicle door of the vehicle, when the vehicle door swings, the vehicle door with the swing assembly installed will move in the opposite direction relative to another vehicle door. After separating from another vehicle door by a certain distance, it will then move laterally, as Figure 8 and Figure 9 shown. When the swing assembly is installed on the rear vehicle door, when the swing assembly swings, its movement trajectory is as Figure 9 shown. The rear vehicle door will move towards the rear of the vehicle, and the moving area is outside the vehicle. The front vehicle door remains stationary, thus realizing the disordered opening of the front and rear vehicle doors. That is to say, there will be no interference between the vehicle doors, and when opening the rear vehicle door, it is not necessary to open the front vehicle door in advance. By using this swing door assembly to replace the traditional guide rail structure, the opening angle of the vehicle door is not limited by the length of the guide rail, and a large opening angle can be achieved within a small space.

[0035] Of course, the connection positions of the upper swing door assembly and the lower swing door assembly of the present invention with the vehicle door can be reversed. Among them, the upper swing door assembly or the lower swing door assembly can also be installed in the middle of the vehicle door, and the same effect can be achieved. In addition, the first mounting seat 1 and the second mounting seat 2 of the present invention can be separate or integral; the fourth mounting seat 4 can be integral or separate.

[0036] Further, the limiting structure includes a lower limiting block 81 and an upper limiting block 28. The lower limiting block 81 is fixed on the third connecting arm 8, and the upper limiting block 28 is fixed on the second connecting arm 7. The upper limiting block 28 and the lower limiting block 81 are matched. To limit the maximum angle between the third connecting arm 8 and the hinge second connecting arm 7, the lower limiting block 81 is fixed on the right side of the third connecting arm 8, and the upper limiting block 28 is fixed on the right side of the second connecting arm 7, so that the swinging angle of the car door is unique. The installation positions of the lower limiting block 81 and the upper limiting block 28 can be adjusted to enable the car door to be opened along different trajectories, so that the swing door assembly can be adjusted according to the needs of users.

[0037] Further, the first mounting seat 1 is hinged to the first connecting arm 6 through a first rotating shaft 17. The first connecting arm 6 and the first rotating shaft 17 are fixedly connected, and specifically, a locking nut can be used for fastening. The driving device 9 is an electric motor. The electric motor drives the first rotating shaft 17 to rotate. The electric motor can be directly fixedly connected to the first rotating shaft 17 or driven by a gear. Specifically, in the first mounting seat 1 of the present invention, the first rotating shaft 17 is rotatably connected through an upper bearing 18 and a lower bearing 19. The first rotating shaft 17 and the first mounting seat 1 are fixedly connected through a loosening prevention structure 21 and a second locking nut 22. Among them, the upper bearing 18 and the lower bearing 19 can also be replaced by a bushing 31, a shaft sleeve, an oil-impregnated bearing, etc. The loosening prevention structure 21 can be a structure for preventing the nut from loosening, such as a plug pin, a check washer, a thread locking adhesive, etc. The electric telescopic rod 10 can be an electric drive mechanism with a telescopic function. The electric motor outputs a driving force to adjust the magnitude, direction, and rotational speed of the force value.

[0038] Further, the fourth mounting seat 4 is a frame-shaped seat, including a vertical plate 35. An upper cross plate 33 is connected above the vertical plate 35, and a lower cross plate 34 is connected below the vertical plate 35. A plurality of mounting holes for connecting to the car door are opened on the vertical plate 35. Specifically, the fourth mounting seat 4 of the present invention is a frame-shaped seat. There is a cavity between the upper cross plate 33 and the lower cross plate 34 of the frame-shaped seat. The third connecting arm 8 can be accommodated through this cavity, so that the third connecting arm 8 will not interfere with the frame-shaped seat when rotating.

[0039] Further, the first mounting seat 1 includes a side seat plate 36, and a set of hinge plates 37 are fixed on the side seat plate 36. The first rotating shaft 17 is rotatably connected between the hinge plates 37. Specifically, if the connection surface between the first mounting seat 1 and the vehicle body 25 of the present invention is parallel to the connection surface between the second mounting seat 2 and the vehicle body 25, it will invade too much space of the vehicle body 25, and the structure of the vehicle body 25 must also be retracted and changed. To avoid this situation, the connection surface between the first mounting seat 1 and the vehicle body 25 is directly at a 90-degree angle to the connection surface between the second mounting seat 2 and the vehicle body 25, and the first mounting seat 1 can be directly mounted on the side wall of the vehicle body 25.

[0040] The present invention further includes a vehicle applying the vehicle swing door assembly, including a vehicle body 25, a front door 23 and a rear door 24 are connected to the vehicle body 25, and the upper swing door assembly and the lower swing door assembly are connected to the rear door 24 and / or the front door 23 of the vehicle. When the vehicle uses this swing door assembly, the upper swing door assembly and the lower swing door assembly of this swing door assembly are a set, and can be separately installed on the front door 23 or the rear door 24 of the vehicle, or can be simultaneously installed on the front door 23 and the rear door 24 of the vehicle, and the user can install them according to specific needs.

[0041] Further, a first sealing strip 26 is fixedly connected to the outer rear door panel 241 of the rear door 24 of the vehicle, and a second sealing strip 27 is fixed to the inner rear door panel 243 of the rear door 24 of the vehicle. In order to enable the vehicle door to have a better sealing effect when closed, a first sealing strip 26 is fixedly connected to the outer rear door panel 241 of the rear door 24 of the vehicle, and a second sealing strip 27 is fixed to the inner rear door panel 243 of the rear door 24 of the vehicle (the outer rear door panel 241 and the inner rear door panel 243 of the rear door 24 are connected by a rear door connecting plate 242). When the rear door 24 is closed, the first sealing strip 26 and the second sealing strip 27 on the rear door 24 achieve an extrusion effect with the front door 23, thereby achieving double sealing. Of course, the first sealing strip 26 and the second sealing strip 27 can also be connected to the front door 23, or the first sealing strip 26 and the second sealing strip 27 are respectively connected to the front door 23 and the rear door 24, and the same effect can be achieved.

[0042] When the present invention specifically controls the swing door assembly, the following scheme can be adopted: a position monitoring sensor is installed on the driving device 9, and the rotation direction, angle, speed and number of revolutions of the driving device 9 are identified and controlled by the BCM control unit or the external ECU control unit of the automobile body 25, so as to realize the opening and closing of the door within a specific time. The electric telescopic rod 10 is also installed with a position monitoring sensor, and the telescopic direction, length and speed of the electric telescopic rod 10 are identified and controlled by the BCM control unit or the external ECU control unit of the automobile body 25, so as to realize the control of the door angle during the opening and closing process of the door. When the driving device 9 is rotated to different positions, the electric telescopic rod 10 is correspondingly telescoped to a specific length, so as to realize the movement trajectory of the rear door 24 in the process of opening the rear door 24, which first moves backward to leave the overlap area at the overlap of the front and rear doors and then opens to the outside of the vehicle. The movement trajectory of the door closing process is opposite to that of the opening process, so that the function of disorderly opening and closing of the front and rear doors 24 can be realized.

[0043] The preferred specific embodiments of the present invention are described in detail above. It should be understood that a person skilled in the art can make many modifications and changes based on the concept of the present invention without creative work. Therefore, any technical solution that can be obtained by a person skilled in the art through logical analysis, reasoning or limited experiments based on the concept of the present invention on the basis of the prior art should be within the scope of protection determined by the claims.
