[0030] In combination Figure 1 As shown, according to specific embodiments of the present application, a vehicle door assembly is provided.

[0031] Specifically, the vehicle door assembly comprises a first row of vehicle doors 1, a second row of vehicle doors 2 and a third row of vehicle doors 3. The first row of vehicle doors 1 is movably connected to an A-pillar 4 of the vehicle body. The second row of vehicle doors 2 is movably connected to a B-pillar 5 of the vehicle body, the second row of vehicle doors 2 has a second closed position and a second open position, and the second row of vehicle doors 2 is movable in a first direction to switch from the second closed position to the second open position. The third row of vehicle doors 3 is movably connected to a D-pillar 7 of the vehicle body, the third row of vehicle doors 3 has a third closed position and a third open position, and the third row of vehicle doors 3 is movable in a second direction to switch from the third closed position to the third open position, the second direction being opposite to the first direction. Wherein, the first row of vehicle doors 1 is arranged close to the front wheels, the third row of vehicle doors 3 is arranged close to the rear wheels, and the second row of vehicle doors 2 is arranged between the first row of vehicle doors 1 and the third row of vehicle doors 3.

[0032] In the embodiments of the present application, the first row of vehicle doors 1 is movably connected to the A-pillar 4, the second row of vehicle doors 2 is movably connected to the B-pillar 5, and the third row of vehicle doors 3 is movably connected to the D-pillar 7 of the vehicle body. The second row of vehicle doors 2 and the third row of vehicle doors 3 are movable in opposite directions, and the second row of vehicle doors 2 and the third row of vehicle doors 3 form a front and rear opposing layout, providing the third row of passengers with independent entrances and exits without the need to adjust the second row of seats to directly enter and exit the vehicle cabin. The second row of vehicle doors 2 and the third row of vehicle doors 3 form a front and rear opposing layout, not only solving the problem of inconvenience for the third row of passengers to enter and exit, but also helping to optimize the opening angle of the vehicle doors. A reasonable vehicle door opening design ensures that passengers will not be injured by collision during the process of getting on and off the vehicle, improving the overall comfort of the riding experience. The vehicle door structure in the above-mentioned solution solves the technical problem of inconvenience for the third row of passengers to enter and exit caused by the structure of the three-row seat vehicle type in the prior art.

[0033] Further, a C-pillar 6 is arranged between the second row of vehicle doors 2 and the third row of vehicle doors 3, the C-pillar 6 is arranged on at least one of the second row of vehicle doors 2 and the third row of vehicle doors 3, a top end of the C-pillar 6 is used to abut against a roof side rail, and a bottom end of the C-pillar 6 is used to abut against a rocker rail of the vehicle body.

[0034] In the embodiments of the present application, the C pillar 6 is arranged between the second row of doors 2 and the third row of doors 3, and when the doors where the C pillar 6 is located are in the closed position, the top end of the C pillar 6 abuts against the roof side rail, and the bottom end of the C pillar 6 abuts against the rocker rail of the vehicle body, that is, the C pillar 6, the roof side rail and the rocker rail form a force frame, which can effectively resist lateral pressure and impact force, and especially when driving at high speed or lateral collision occurs, it can provide stronger safety protection for the vehicle occupants. When the second row of doors 2 and the third row of doors 3 are in the opposite opening state, the C pillar 6 moves with the doors, which can reserve more space for passengers to get on and off the vehicle.

[0035] Specifically, the C pillar 6 comprises a first component segment and a second component segment. The first component segment is arranged on the second row of doors 2, and the first component segment extends along the height direction of the second row of doors 2. When the second row of doors 2 is in the second closed position, the top end of the first component segment abuts against the roof side rail, and the bottom end of the first component segment abuts against the rocker rail of the vehicle body. The second component segment is arranged on the third row of doors 3, and the second component segment extends along the height direction of the third row of doors 3. When the third row of doors 3 is in the third closed position, the top end of the second component segment abuts against the roof side rail, and the bottom end of the second component segment abuts against the rocker rail of the vehicle body.

[0036] In the embodiments of the present application, when the second row of doors 2 is in the closed state, the first component segment of the C pillar 6 abuts against the roof side rail and the rocker rail of the vehicle body in the vertical direction, forming a lateral support of the lateral frame of the vehicle body. When the third row of doors 3 is in the closed state, the second component segment of the C pillar 6 abuts against the roof side rail and the rocker rail of the vehicle body in the vertical direction, forming a lateral support of the lateral frame of the vehicle body, thereby enhancing the rigidity of the lateral structure of the vehicle body. During driving of the vehicle, the vehicle body can remain stable under the action of lateral force and effectively resist deformation, thereby improving the safety performance of the vehicle when facing lateral impact. When the second row of doors 2 is in the second closed position and the third row of doors 3 is in the third closed position, the first component segment, the second component segment, the roof side rail and the rocker rail of the vehicle body collectively form a closed frame, further improving the support ability of the C pillar 6 to the lateral frame of the vehicle body. Among them, the two component segments of the C pillar 6 are arranged on the second row of doors 2 and the third row of doors 3, that is, the first component segment and the second component segment are arranged on the second row of doors 2 and the third row of doors 3 as force points, which not only increases the lateral structure of the vehicle body, but also increases the strength of the second row of doors 2 and the third row of doors 3, thereby improving the anti-impact performance of the second row of doors 2 and the third row of doors 3.

[0037] Specifically, the top end of the first component segment abuts against the roof side rail through a sealing strip, and the bottom end of the first component segment abuts against the rocker rail of the vehicle body through a sealing strip. The top end of the second component segment abuts against the roof side rail through a sealing strip, and the bottom end of the second component segment abuts against the rocker rail of the vehicle body through a sealing strip.

[0045] The locking structure is also equipped with an inside door switch and an outside door switch, and the third row door 3 can be opened by pressing the door opening switch, otherwise it cannot be opened.

[0046] The third row door 3 is equipped with an anti-pinch sensor, which automatically stops opening and reversely closes when an obstacle is detected.

[0047] In an exemplary embodiment of the present application, the second row door 2 can rotate relative to the B pillar 5 in a first direction, and the third row door 3 can rotate relative to the D pillar 7 in a second direction.

[0048] In the embodiment of the present application, the third row door 3 is added on the basis of ensuring that the connection mode of the second row door 2 remains unchanged, and the connection mode of the third row door 3 is the same as that of the second row door 2, which makes the overall installation structure of the doors symmetrical on the basis of low cost.

[0049] Specifically, the second row door 2 is rotatably connected with the B-pillar 5 through a hinge structure, the hinge structure has a rotation shaft arranged in a vertical direction, and the maximum opening angle of the second row door 2 is 65°-80°.
