[0028] Next, the embodiments of the present application will be described in detail.

[0029] In the related art, most vehicles use a conventional swing door structure, and the vehicle door and the vehicle body are hingedly connected by a hinge. When the vehicle door is opened, the vehicle door needs to be rotated by a large angle to increase the passing area, and the convenience of getting on and off the vehicle is poor. In addition, when the vehicle door is opened by a large angle, the vehicle door occupies a large space outside the vehicle body. Some vehicles use a swing door opening and closing structure, and the vehicle door and the vehicle body are connected by connecting rods. However, the connection structure between the connecting rods is complex, which limits the opening angle of the swing door, and the driving mechanism for driving the connecting rods occupies a large space.

[0030] Therefore, the application provides a vehicle door opening and closing movement mechanism and a vehicle, which can greatly increase the vehicle door passing area and improve the convenience of passengers getting on and off the vehicle.

[0031] As shown in FIG. 1, the application provides a vehicle door opening and closing movement mechanism, which comprises a swing arm beam 10, a swing arm 20 and a bracket 30. One end of the swing arm 20 is connected to the swing arm beam 10, and the other end of the swing arm 20 is connected to the bracket 30. The one end of the swing arm 20 can rotate around the swing arm beam 10 to drive the bracket 30 at the other end of the swing arm 20 to rotate. In this way, the vehicle door passing area can be greatly increased, and the convenience of passengers getting on and off the vehicle can be improved, and it is also convenient for passengers to put down and take up luggage.

[0032] In some embodiments, the bracket 30 comprises a vehicle door mounting rack 31, and a vehicle door (not shown in the figure) is mounted on the vehicle door mounting rack 31. The vehicle door mounting rack 31 is arranged in parallel with the swing arm beam 10, that is, during the swing of the swing arm 20, the vehicle door mounting rack 31 is always arranged in parallel with the swing arm beam 10; and then the distance between the vehicle door on the vehicle door mounting rack 31 and the vehicle body is kept consistent during the opening process, and the safety is good.

[0033] Further, generally, the vehicle door on the vehicle door mounting rack 31 is arranged along the length direction of the vehicle, and therefore, according to the parallel arrangement of the vehicle door mounting rack 31 and the swing arm beam 10, the swing arm beam 10 is also connected to the vehicle body along the length direction of the vehicle. When the vehicle door mounting rack and the swing arm beam are arranged at an angle, an adapter or a support and the like need to be arranged at the angle between the vehicle door mounting rack and the swing arm beam; and in addition, the vehicle door mounting rack needs to be fixed at a position at an angle to the length direction of the vehicle, such as the top of the vehicle or the width direction of the vehicle, which occupies a large space and has a complex structure.

[0034] Referring to FIGS. 1-2, the bracket 30 further comprises a first swing arm 32, a first motor 33 and a first bearing 34. One end of the first swing arm 32 is rotatably connected to the swing arm 20 through the first bearing 34, and the other end of the first swing arm 32 is fixedly connected to the vehicle door mounting rack 31. The first swing arm 32 is arranged perpendicularly to the vehicle door mounting rack 31.

[0035] Specifically, in this embodiment, the first motor 33 is connected to the swing arm 20 and coaxially arranged with the first bearing 34. The first motor 33 drives the first swing arm 32 to rotate around the first bearing 34 to adjust the position of the vehicle door mounting rack 31 in the bracket 30. That is, the first swing arm 32 is always perpendicular to the swing arm beam 10, and then the vehicle door mounting rack 31 is arranged in parallel with the swing arm beam 10.

[0036] The door is installed in parallel with the door mounting frame 31 through the mounting hole 311. In addition, the door mounting frame 31 is arranged perpendicularly to the first swing arm 32 in the embodiment, and the advantage of the design is that when the door mounting frame 31 is rotated to be parallel to the swing arm beam 10, the swing distance of the first swing arm 32 is short, and the overall structural stability of the door mounting frame 31 and the first swing arm 32 is strong. Of course, the door mounting frame 31 can also be arranged at an angle with the first swing arm 32, for example, the door mounting frame 31 is arranged at a non-right angle with the first swing arm 32.

[0037] Optionally, the door mounting frame 31 is integrally formed with the first swing arm 32, so as to improve the strength of the overall structure and avoid separation of the door mounting frame 31 and the first swing arm 32 due to the weight of the door on the door mounting frame 31.

[0038] Referring to FIGS. 1-2, the swing arm assembly 20 includes a second swing arm 21, a third swing arm 22, a second motor 23, a third motor 24, a second bearing 25, and a third bearing 26. One end of the second swing arm 21 is rotationally connected to the first swing arm 32 through the first bearing 34, and the other end of the second swing arm 21 is rotationally connected to one end of the third swing arm 22 through the second bearing 25; the other end of the third swing arm 22 is rotationally connected to the swing arm beam 10 through the third bearing 26. The second motor 23 is connected to the third swing arm 22 and coaxially arranged with the second bearing 25, and the second motor 23 can drive the second swing arm 21 to rotate around the second bearing 25. The third motor 24 is connected to the swing arm beam 10 and coaxially arranged with the third bearing 26, and the third motor 24 can drive the third swing arm 22 to rotate around the third bearing 26.

[0039] As an example, the swing arms, the motors, and the bearings are connected through spline connection. The following takes the third swing arm 22, the third motor 24, and the third bearing 26 as an example to describe the connection between the swing arms, the motors, and the bearings. The outer ring of the third bearing 26 can be fixed to the swing arm beam 10, and the third swing arm 22 can be connected to the motor shaft of the third motor 24 and the inner ring of the third bearing 26 through spline connection, so that the third motor 24 can drive the third swing arm 22 to rotate around the third bearing 26 through spline. The connection between the other swing arms, the motors, and the bearings is similar, and will not be described in detail.

[0040] In the embodiment, the swing arm assembly 20 includes two swing arms, the second swing arm 21 and the third swing arm 22, but the application is not limited thereto. The swing arm assembly 20 can also include three swing arms, four swing arms, etc., and the swing arms are connected in series through bearings in sequence.

[0041] In the embodiment, the length of the second swing arm 21 is greater than the sum of the lengths of the third swing arm 22 and the first swing arm 32.

[0042] Further, the length of the first swing arm 32 is less than the length of the third swing arm 22. In the present embodiment, the opening of the door is mainly realized by the rotation of the second swing arm 21 and the third swing arm 22, and thus the greater the length of the second swing arm 21 and the third swing arm 22, the greater the swing distance of the second swing arm 21 and the third swing arm 22, and according to the user's needs, the door can be stopped at any position.

[0043] Referring to FIGS. 1-2, the side of the swing arm beam 10 is provided with a groove 11, when the second swing arm 21 and the third swing arm 22 are parallel to the swing arm beam 10, the second swing arm 21 and the third swing arm 22 are accommodated in the groove 11, and the groove 11 plays a role of accommodating the second swing arm 21 and the third swing arm 22.

[0044] In addition, in the present embodiment, the top of the swing arm beam 10 is provided with a notch 12, and the notch 12 is in communication with the groove 11. When the second swing arm 21 and the third swing arm 22 are parallel to the swing arm beam 10, the first motor 33 and the second motor 23 are accommodated in the notch 12, so as to avoid interference between the first motor 33 and the second motor 23 and the swing arm beam 10.

[0045] Of course, when the first motor 33 and the second motor 23 are located below the first swing arm 32 and the second swing arm 21, the corresponding notch 12 can also be arranged at the bottom of the swing arm beam 10.

[0046] In the process of the third swing arm 22 rotating from the position parallel to the swing arm beam 10 in the process of opening the door to the position forming an angle with the swing arm beam 10 in the open state of the door, that is, in the process of the third swing arm 22 rotating from FIG. 4 to FIG. 5, the distance L of the door mounting bracket 31 relative to the swing arm beam 10 is unchanged.

[0047] Through the above design, the distance L between the door on the door mounting bracket 31 and the vehicle body can be kept at a certain value during the swing process, so as to avoid the distance between the door and the vehicle body changing and the passenger being pinched.

[0048] The present application also provides a vehicle comprising the door opening and closing movement mechanism. The vehicle includes but is not limited to a car, a passenger car, etc. By installing the door opening and closing movement mechanism on the vehicle, the door is changed from a rotary door structure to a swing door structure, the door can be swung to the limit position by a large angle, the door does not block the door opening of the vehicle body, the door opening of the vehicle body is used to the extreme, and the convenience of passengers getting on and off the vehicle is improved. The swing door can realize the stop function, and according to the user's needs, the swing door can be stopped at any position.
