[0050] Combine the following Figures 1 to 6 , describing an embodiment of the utility model.
[0051] According to an embodiment of the present utility model, on one hand, a vehicle door device is provided, comprising:
[0052] A first door 100 is pivotally connected to an A-pillar of the vehicle;
[0053] A second door 200 is pivotally connected to the B-pillar of the vehicle;
[0054] The third door 300 is pivotally connected to the rear of the vehicle body 400 via the hinge assembly 1 , and an anti-collision structure is disposed on the third door 300 .
[0055] The third door is provided with an anti-collision structure, which improves the impact resistance and reliability of the third door, improves the safety of the third-row doors, and thus can improve the overall safety of the three-row seat vehicle.
[0056] In one embodiment, Figure 1 As shown, the anti-collision structure includes an anti-collision beam 2 extending along the height direction of the third door 300 .
[0057] The door device is provided with A-pillar and B-pillar supports near the first door 100 and the second door 200, and an anti-collision beam 2 is provided on the third door 300 and extends along the height direction of the third door 300, which can act as a pillar to support and strengthen the third door 300 and improve the overall safety of the door device.
[0058] In one embodiment, the bending shape of the anti-collision beam 2 is adapted to the contour of the third door 300 on the side close to the second door 200 .
[0059] The extension direction of the anti-collision beam 2 is adapted to the contour of the side thereof close to the second door 200. With such an arrangement, the reinforcement consistency along the height direction is better, weak points are avoided, and the safety and reliability of the vehicle are improved.
[0060] In one embodiment, the anti-collision beam 2 is disposed on a side of the third door 300 close to the second door 200 .
[0061] There is no pillar support between the third door 300 and the second door 200 , so the anti-collision beam 2 is arranged on the side close to the second door 200 , which meets the force and support requirements and improves anti-collision safety.
[0062] In one embodiment, Figure 2 As shown, the anti-collision beam 2 is a hollow beam.
[0063] The anti-collision beam 2 adopts a hollow beam, which can maximize the lightweight design while ensuring strength, which is in line with the trend and demand of vehicle lightweighting.
[0064] In one embodiment, the anti-collision beam 2 is prism-shaped.
[0065] The use of a prismatic anti-collision beam 2 can improve the supporting strength and further increase the possibility of lightweighting.
[0066] In one embodiment, the anti-collision structure further includes sky and ground locks arranged at both ends of the anti-collision beam 2 .
[0067] The third door is connected to the frame through a top and bottom lock, which improves the connection reliability of the third door in both the upper and lower directions and can further improve anti-collision safety.
[0068] Specifically, the sky lock includes a sky lock 3 arranged on the upper side of the anti-collision beam 2 and a ground lock 4 arranged on the lower side of the anti-collision beam 2 .
[0069] In one embodiment, Figure 3 As shown, the gooseneck hinge includes:
[0070] A vehicle body side bracket 11, adapted to be mounted to a vehicle body 400;
[0071] The door side bracket 12 is adapted to be mounted to the third door 300;
[0072] The gooseneck connection part 13 has a first end fixedly connected to the vehicle body side bracket 11 and a second end pivotally connected to the vehicle door side bracket 12 .
[0073] The gooseneck hinge is connected to the vehicle body 400 and the third door 300 through the vehicle body side bracket 11 and the door side bracket 12 respectively, and the connection is stable and reliable; the gooseneck hinge bears the weight of the third door 300 and maintains the balance between the third door 300 and the vehicle body 400; and the structure is simple, and the reliability is higher than that of the hinge structure with a complex structure. In addition, the reasonable mechanical structure distributes the dead weight of the door between the gooseneck connection part 13 and the vehicle body side bracket 11 and the door side bracket 12, thereby reducing the pressure at a single connection and improving the stability and durability of the entire device. The second end of the gooseneck connection part 13 is pivotally connected to the door side bracket 12, which can easily control the opening angle of the third door 300, and has a long torque, making it easier to open and close the door.
[0074] Specifically, by designing the bending curvature of the gooseneck connection portion 13, the opening angle of the third door 300 can be controlled. Figure 3The gooseneck hinge shown can achieve an opening angle of the third door 300 within a range of 90 to 100 degrees, which can not only provide sufficient space for boarding and alighting, but also reduce the risk of collision with the surrounding environment or obstacles, thereby improving the convenience of boarding and alighting for the third row of passengers. Compared with the method in which the two connecting arms of the gooseneck connecting portion 13 are approximately parallel in the related art (the opening angle can reach 180 degrees), under the premise of meeting the boarding and alighting space requirements, an opening angle greater than 100 degrees is not very meaningful and is also prone to collision and interference with surrounding objects.
[0075] In one embodiment, the hinge assembly 1 is disposed in the middle of the third door 300. A gooseneck hinge is used, which can bear the weight of the third door 300, greatly improving reliability compared with ordinary hinges. Only one hinge assembly 1 is disposed in the middle of the third door 300, and the balance between the third door 300 and the vehicle body 400 can be maintained, simplifying the structure and reducing costs. Moreover, the gooseneck hinge of the utility model is small in size and light in weight, contributing to the lightweighting of the vehicle.
[0076] The vehicle body side bracket 11 of the gooseneck hinge is triangular, and the pivot point of the gooseneck connecting portion 13 is located at a corner of the triangular vehicle body side bracket 11 .
[0077] The pivot point of the gooseneck connection portion 13 is located at a corner of the triangular vehicle body side bracket 11, which reduces interference and makes the structure more compact.

[0079] First row of seats;
[0080] Second row seats;
[0081] third row of seats;
[0082] The vehicle body 400, the first door 100 corresponds to the first row of seats, the second door 200 corresponds to the second row of seats; and the third door 300 corresponds to the third row of seats.
[0083] like Figure 1 and Figure 4 As shown, the rear end of the third door 300 is connected to the vehicle body 400 and the third door 300 through a gooseneck hinge, and an anti-collision beam 2 for strengthening support is provided from top to bottom on the front side of the third door 300 close to the second door 200 (away from the side of the hinge assembly 1), and a sky lock 3 and a ground lock 4 are respectively provided near the upper and lower ends of the anti-collision beam 2, for locking the third door 300 to the vehicle body 400; at the same time, a door lock or a lock buckle is provided in the middle of the front end of the third door 300, for engaging and locking with the lock buckle or door lock at the corresponding position of the second door.
[0084] like Figure 2 As shown, Figure 1 The AA section in the figure shows the cross section of the through anti-collision beam 2 arranged in the third door 300, and its structure is an ultra-high strength tubular structural beam, such as a hot-formed beam or an ultra-high strength steel beam.
[0085] like Figure 3 As shown, Figure 1 The BB section in the figure shows that the opening direction of the third door 300 is to rotate opposite to the second door 200, and the opening angle is greater than 90°. When the third door is opened, the entire door will swing to the outside of the vehicle body, which is commonly known as an outward-opening door. (The solid line and dotted line in the figure respectively represent the third door 300 in the closed and open states).
[0086] In one embodiment, the third door 300 opens opposite to the second door 200. Figure 5 and Figure 6 shown.
[0087] The third door 300 opens opposite to the second door 200 , and both the second door 200 and the third door 300 can be opened when needed, which can further improve the convenience for the third row passengers to get on and off the vehicle.
[0088] In one embodiment, a safety lock 5 is provided between the third door 300 and the second door 200. Specifically, a door lock can be provided in the middle of one of the third door 300 and the second door 200, and a lock catch can be provided in the middle of the other to lock the third door 300 and the second door 200, thereby improving safety.
[0089] The utility model has the following beneficial effects: the third door 300 of the vehicle can be closed for a long time when not in use, without affecting the use of the second door 200; the three-row special door can be opened more than 90°, providing passengers with maximum convenience in getting on and off the vehicle; the third door of the third row special door is designed with an anti-collision beam 2 and a sky and earth lock that penetrate from top to bottom to ensure safety; passengers can easily enter the third row space of the vehicle from the side through the fully opened special door; the rear door of the vehicle is connected to the third row door through a conventional door lock to ensure side collision safety.
