[0040] The vehicle door structure of the present application includes a door body, a first drive structure, a second drive structure and a third drive structure. When the vehicle door is opened or closed, the door body moves along the front and rear directions of the vehicle body and also swings along the left and right directions of the vehicle body, thereby allowing more air outside the vehicle to enter the vehicle and ensure air exchange between the inside and outside of the vehicle.

[0041] The following will describe in detail various embodiments of the present application that are consistent with the above-mentioned creative concepts.

[0042] like Figures 1 to 9 As shown, the embodiment of the present application discloses a vehicle door structure, which is a sliding door. The vehicle door structure includes a door body 100, a first drive structure 300, a second drive structure 400 and a third drive structure 500, and the door body 100 is connected to the vehicle body 200 through the first drive structure 300, the second drive structure 400 and the third drive structure 500.

In the present embodiment, the first connection seat 10 and the second connection seat 20 are arranged at the same height. The first connection seat 10 and the second connection seat 20 are both fixed to the lower side of the vehicle. The first connection seat 10 is relatively arranged behind the second connection seat 20. The third connection seat 30 is arranged on the upper side of the vehicle body 200. The first connection seat 10, the second connection seat 20 and the third connection seat 30 can be manufactured independently and fixed to the vehicle body 200 by welding or the like, or they can be integrally formed with the vehicle body 200.

[0044] like Fig. 9 as well as Fig.10 As shown, the first driving structure 300 includes a first connecting rod 11 and a first driving device 12 .

[0045] One end of the first connecting rod 11 is rotatably connected to the door body 100, and the other end of the first connecting rod 11 is rotatably connected to the first connecting seat 10. Specifically, the first connecting rod 11 can rotate around an axis along the up-down direction of the vehicle body relative to the connection point with the door body 100, and the first connecting rod 11 can rotate around an axis along the up-down direction of the vehicle body relative to the connection point with the first connecting seat 10.

[0046] The first driving device 12 is connected to the first connecting rod 11. The first driving device 12 is configured to drive the first connecting rod 11 to rotate around the first connecting seat 10, and drive the door body 100 to move along the front-rear direction of the vehicle body through the first connecting rod 11. The first driving device 12 includes a first power unit 121. Optionally, the first power unit 121 can be a driving motor, an electric push rod or a hydraulic cylinder, etc. In this embodiment, the first power unit 121 is a driving motor.

[0047] The second driving structure 400 includes a second connecting rod 21 , a third connecting rod 22 and a second driving device 23 .

[0048] One end of the second connecting rod 21 is rotatably connected to the second connecting seat 20, and the other end is rotatably connected to the third connecting rod 22. One end of the third connecting rod 22 is rotatably connected to the door body 100, and the other end is rotatably connected to the second connecting rod 21. Specifically, the second connecting rod 21 can rotate around an axis along the up-down direction of the vehicle body relative to the connection point with the second connecting seat 20, and the second connecting rod 21 can rotate around an axis along the up-down direction of the vehicle body relative to the connection point with the third connecting rod 22. The third connecting rod 22 can rotate around an axis along the up-down direction of the vehicle body relative to the connection point with the door body 100, and the third connecting rod 22 can rotate around an axis along the up-down direction of the vehicle body relative to the connection point with the second connecting rod 21.

[0049] The second driving device 23 is connected to the third connecting rod 22, and the second driving device 23 is configured to drive the third connecting rod 22 to rotate around the second connecting rod 21. The second driving device 23 includes a second power unit 231. Optionally, the second power unit 231 can be a driving motor, an electric push rod, a hydraulic cylinder, etc. In this embodiment, the second power unit 231 is an electric push rod. One end of the electric push rod is connected to an end of the third connecting rod 22 close to the door body 100, and the other end of the electric push rod is connected to an end of the second connecting rod 21 close to the vehicle body 200. The electric push rod drives the third connecting rod 22 to rotate around the second connecting rod 21 by its own extension and contraction.

[0050] like Figures 10 to 12 As shown, the third driving structure 500 includes a fourth connecting rod 31. One end of the fourth connecting rod 31 is rotatably connected to the door body 100, and the other end of the fourth connecting rod 31 is rotatably connected to the third connecting seat 30. Specifically, the fourth connecting rod 31 can rotate around an axis along the up-down direction of the vehicle body relative to the connection point with the third connecting seat 30, and the fourth connecting rod 31 can rotate around an axis along the up-down direction of the vehicle body relative to the connection point with the door body 100.

[0051] In an optional embodiment, the vehicle body 200 is further provided with a fourth connection seat 32. The fourth connection seat 32 is arranged on the upper side of the vehicle body 200 and on the front side of the third connection seat 30. The third driving structure 500 also includes a third driving device 33. One end of the third driving device 33 is rotatably connected to the fourth connection seat 32, and the other end of the third driving device 33 is rotatably connected to a side of the fourth connecting rod 31 close to the third connection seat 30. Specifically, the third driving device 33 can rotate around an axis along the up-down direction of the vehicle body relative to the connection point with the fourth connection seat 32, and the third driving device 33 can rotate around an axis along the up-down direction of the vehicle body relative to the connection point with the fourth connecting rod 31. The third driving device 33 can be an electric push rod, which drives the fourth connecting rod 31 to rotate by its own extension and contraction, thereby pushing the door body 100 to move.

[0052] The connecting rod structure formed by the first connecting rod 11 , the second connecting rod 21 , the third connecting rod 22 and the fourth connecting rod 31 can control the movement of the entire door body 100 by controlling the movement of three points on the door body 100 .

[0053] like Figures 2 to 6 As shown, Figures 2 to 6 The process of the door structure from the closed state to the open state is shown. Figure 2 In the closed state shown in FIG. 1 , the first driving device 12 drives the first connecting rod 11 to rotate counterclockwise around the first connecting seat 10, and the second driving device 23 itself extends and contracts, thereby adjusting the state of the door in the left and right directions, and finally reaching the state shown in FIG. Figure 6 Shown in fully open position.

[0054] like Figure 7 and Figure 8As shown, the door structure includes a swinging state. When the door structure is in the swinging state, the first driving device 12 drives the first connecting rod 11 to rotate around the connection point with the first connecting seat 10 to drive the door body 100 to move along the front-rear direction of the vehicle body. Specifically, the first driving device 12 drives the first connecting rod 11, thereby driving the connection point between the first connecting rod 11 and the door body 100 to move, and then driving the door body 100 to move. At this time, the connection point between the first connecting rod 11 and the door body 100 moves toward the rear of the vehicle body along a curved trajectory. The curved trajectory can be decomposed into a trajectory perpendicular to the front-rear direction of the vehicle body and a trajectory parallel to the front-rear direction of the vehicle body. At the same time, the third driving device 33 drives the fourth connecting rod 31 to rotate around the connection point with the first connecting seat 10 to drive the door body 100 to move along the front-rear direction of the vehicle body. Specifically, the third driving device 33 drives the fourth connecting rod 31, thereby driving the connection point between the fourth connecting rod 31 and the door body 100 to move, and then driving the door body 100 to move. At this time, the connection point between the fourth link 31 and the door body 100 moves toward the rear of the vehicle body along a curved trajectory. The curved trajectory is the same as the movement trajectory of the connection point between the first link 11 and the door body 100. The second driving device 23 drives the third link 22 to rotate around the connection point with the second link 21 to drive the door body 100 to swing along the left and right directions of the vehicle body. Figure 7 Exercise to Figure 8 During the process, the first driving device 12 drives the first connecting rod 11 to rotate counterclockwise, and at the same time, the second driving device 23 extends itself to drive the third connecting rod 22 to rotate around the connection point with the second connecting rod 21, so that the door body 100 swings left and right while moving forward and backward. Figure 7 and Figure 8 They respectively indicate that the door body 100 is in different swinging postures. Figure 7 The door body 100 shown is located at Figure 8 The door body 100 is shown in a forward position. Figure 7 The angle between the door body 100 and the front-rear direction of the vehicle body is greater than Figure 8 The angle between the door body 100 and the front-rear direction of the vehicle body. Figure 7 The angle a between the door body 100 and the front-rear direction of the vehicle body is less than or equal to 60° and greater than or equal to 30°. Figure 8 The angle b between the door body 100 and the front-rear direction of the vehicle body is less than or equal to 30°. Figure 7 and Figure 8 The door body 100 shown is in a state where the rear side is swung away from the vehicle body. In other optional embodiments, the door body 100 can be in a state where the rear side is swung toward the vehicle body. At this time, the angle between the door body 100 at the front position and the front-to-back direction of the vehicle body is greater than the angle between the door body 100 at the rear position and the front-to-back direction of the vehicle body.

[0055] Thus, the door structure realizes a state in which the door body 100 moves in the front-rear direction of the vehicle body and swings in the left-right direction of the vehicle body at the same time, that is, the door structure realizes a swinging state, so that more air outside the vehicle can enter the vehicle, ensuring air exchange between the vehicle and the outside.

[0056] like Fig. 9 As shown, in an optional embodiment, the first driving structure 300 further includes a damping rod 13. One end of the damping rod 13 is connected to the first connecting seat 10, and the other end of the damping rod 13 is connected to the first connecting rod 11. Optionally, one end of the damping rod 13 is connected to a side of the second connecting seat 20 close to the first connecting seat 10, and the other end of the damping rod 13 is connected to a side of the first connecting rod 11 close to the first connecting seat 10. The damping rod 13 can save energy consumption of the first driving device 12, so that the first driving device 12 can drive the rotation of the first connecting rod 11 with less power.

[0057] In an optional embodiment, the second connecting rod 21 includes a limiting portion 211, which is disposed in the middle section of the second connecting rod 21, and the width of the limiting portion 211 is greater than the width of other parts of the second connecting rod 21. The limiting portion 211 can limit the movement of the second connecting rod 21.

[0058] like Fig.13 As shown, in an optional embodiment, the door structure includes a controller 600. The first drive device 12 includes a first power unit 121 and a first position sensor 122. The second drive device 23 includes a second power unit 231 and a second position sensor 232. The third drive device 33 includes a third power unit 331 and a third position sensor 332.

[0059] The controller 600 controls the first power unit 121, the second power unit 231 and the third power unit 331 based on the position of the first power unit 121 detected by the first position sensor 122, the position of the second power unit 231 detected by the second position sensor 232 and the position of the third power unit 331 detected by the third position sensor 332. The positions of the power units can be data such as the position angle or position stroke of the motor rotation. By controlling the first drive device 12, the second drive device 23 and the third drive device 33, the door body 100 can be driven to move, so that the door structure reaches a swinging state.

[0060] As described above, the swing state of the door body 100 can be realized by electric control of one controller 600, or by electric control of multiple controllers 600. For example, the first controller 600 is responsible for collecting information of the first position sensor 122 and controlling the first power unit 121, the second controller 600 is responsible for collecting information of the second position sensor 232 and controlling the second power unit 231, and the third controller 600 is responsible for collecting information of the third position sensor 332 and controlling the third power unit 331. The three controllers 600 synchronize the states of the three power units in real time through bus information, thereby realizing the control of the first drive device 12, the second drive device 23 and the third drive device 33. In this way, the movement of the first power unit 121, the second power unit 231 and the third power unit 331 can be associated. For example, the position angle or position stroke of the second power unit 231 can be set according to the position angle or position stroke of the first power unit 121. The position angle or position stroke of the third power unit 331 can also be set according to the position angle or position stroke of the first power unit 121.

[0061] The present application also discloses a vehicle, which may be a vehicle without a B-pillar, and the vehicle includes the above-mentioned door structure.

The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the drawings; all modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of this application should be included in the scope of protection of this application.
