[0034] Hereinafter, with reference to the accompanying drawings, a limiting structure 100 for a vehicle door assembly 200 according to an embodiment of the present invention will be described. The vehicle door assembly 200 includes a door frame 101 and a vehicle door 102 which are movably connected.

[0035] like Figure 1-Figure 2 As shown, the limiting structure 100 includes a first limiting member 1 and a second limiting member 2. The first limiting member 1 includes a first limiting portion 11 and a second limiting portion 12. The first limiting portion 11 has a first side surface 1a and a second side surface 1b arranged opposite to each other along a first direction. The first side surface 1a is suitable for connecting to one of the door frame 101 and the vehicle door 102. The second limiting portion 12 is arranged on the second side surface 1b and the second limiting portion 12 protrudes in the first direction away from the first side surface 1a. Exemplarily, in combination with Figure 2 and Figure 5The first side surface 1a is fixedly arranged (for example, by welding or bolting, etc.) on the door frame 101, the second limiting portion 12 is arranged on the second side surface 1b and protrudes along the first direction away from the first side surface 1a, and the second limiting portion 12 is formed into a column-like structure; for example, the first limiting portion 11 includes a first section and a second section, the first section is connected to the second section to form an L-shaped structure, the first section has a first side surface 1a on the side away from the second section, and the second section has a second side surface 1b on the side away from the first end, the first side surface 1a and the second side surface 1b are arranged opposite to each other along the first direction, and the area of ​​the first side surface 1a is larger than the area of ​​the second side surface 1b, so that the first limiting portion 11 has a suitable contact area to be fixedly connected to the door frame 101, which is beneficial to improve the stability of the first limiting member 1 arranged on the door frame 101; of course, the first limiting portion 11 can also be constructed as a plate-like structure.

[0036] The second limiting member 2 includes a third limiting portion 21 and a fourth limiting portion 22. The third limiting portion 21 has a first end 21a and a second end 21b that are oppositely arranged along the second direction. The first end 21a is suitable for connecting to the other of the door frame 101 and the vehicle door 102. The fourth limiting portion 22 is arranged at the second end 21b and protrudes from the third limiting portion 21 along the third direction. Figure 2 and Figure 6 The third limiting portion 21 is formed into a long arm-like structure, and the third limiting portion 21 has a second direction (for example, the extension direction of the third limiting portion 21, refer to Figure 2 ) is provided with a first end 21a and a second end 21b opposite to each other, the first end 21a is adapted to be fixedly connected to the vehicle door 102, the second end 21b is connected to a fourth limiting portion 22, and the fourth limiting portion 22 extends in a third direction (e.g., a direction perpendicular to the extending direction of the third limiting portion 21, see Figure 3 ) extends and protrudes from the third limiting portion 21.

[0037] The first limiting member 1 and the second limiting member 2 slide and cooperate along the first direction to switch the limiting structure 100 between the locked state and the unlocked state. In the locked state, the first limiting portion 11 is suitable for limiting and cooperating with the third limiting portion 21 in the first direction and the second limiting portion 12 is suitable for limiting and cooperating with the fourth limiting portion 22 in the second direction, so as to limit the movement of the vehicle door 102 toward the inner side of the vehicle door assembly 200. The first direction is the inner and outer direction of the vehicle door assembly 200, and the first direction, the second direction and the third direction intersect each other. Thus, in the locked state, the first limiting member 11 and the second limiting member 21 are suitable for limiting and cooperating with each other in the first direction to limit the movement of the vehicle door 102 toward the inner side of the vehicle door assembly 200 in the first direction, and the first limiting member 11 and the second limiting member 21 are suitable for limiting and cooperating with each other in the second direction to further limit the movement of the vehicle door 102 toward the inner side of the vehicle door assembly 200 in the first direction. When the outer side of the door assembly 200 is hit (for example, the vehicle is hit from the side), the door 102 has a tendency to move toward the inner side of the door assembly 200 relative to the door frame 101, and the first limiting portion 11 cooperates with the third limiting portion 21 in the first direction to limit the movement of the door 102 toward the inside of the door assembly 200, so that the intrusion amount of the door 102 toward the inner side of the door assembly 200 can be reduced, and the intrusion degree of the door 102 toward the inside due to side impact and the like can be reduced; secondly, the second limiting portion 12 cooperates with the fourth limiting portion 22 in the second direction to limit the movement of the second limiting portion 12 and the fourth limiting portion 22 in the second direction, so that the first limiting portion 11 The first limiting portion 11 and the third limiting portion 21 remain in a limiting matching state, which to a certain extent avoids the separation of the first limiting portion 11 and the third limiting portion 21 due to deformation of the vehicle door 102 when the vehicle door 102 invades the inner side of the vehicle door assembly 200, thereby allowing the first limiting portion 11 and the third limiting portion 21 to remain in a limiting matching state, so that the limiting structure 100 can limit the movement of the vehicle door 102 toward the inside of the vehicle door assembly 200 when the outer side of the vehicle door assembly 200 is impacted, thereby improving the side collision performance of the vehicle, which is beneficial to reducing the possibility of affecting the safety of the occupants in the vehicle due to the vehicle door 102 invading the inner side of the vehicle door assembly 200 (for example, the interior of the vehicle), that is, improving the safety of the occupants in the vehicle. In the unlocked state, the first limit member 1 and the second limit member 2 are separated, and at the same time, the first limit member 1 and the second limit member 2 slide and cooperate along the first direction to realize the switching of the limit structure 100 between the locked state and the unlocked state, so that one of the first limit member 1 and the second limit member 2 can move (for example, rotate, etc.) with the vehicle door 102 relative to the door frame 101, which can reduce or avoid the influence of the limit structure 100 on the opening or closing of the vehicle door 102 to ensure the normal opening and closing of the vehicle door 102.Obviously, the first limit member 1 and the second limit member 2 are unidirectionally limited in the first direction. For example, with respect to the second limit member 2 relative to the first limit member 1, the second limit member 2 can move freely in the positive direction along the first direction relative to the first limit member 1, while the movement of the second limit member 2 relative to the first limit member 1 in the reverse direction along the first direction will be restricted as the limit structure 100 is switched to the locked state.

[0038] Exemplarily, the door 102 is slidably matched with the door frame 101. When the door 102 is closed, the limiting structure 100 is in a locked state, and the first limiting member 1 is limitedly matched with the second limiting member 2. When the door 102 is switched from closed to open, the door 102 first slides a certain distance relative to the door frame 101 toward the outside of the door assembly 200, so that the first limiting member 1 and the second limiting member 2 slide relatively along the first direction until the limiting structure 100 is switched to the unlocked state, and then the door 102 is opened in a direction perpendicular to the inner and outer directions of the door assembly 200 (for example, Figure 1 The vehicle door 102 slides relative to the door frame 101 in the front-to-rear direction of the vehicle door 102 to open the vehicle door 102.

[0039] For example, combined with Figure 1-Figure 2, the vehicle door 102 is rotatably matched with the door frame 101, the first limiting member 1 is provided on the door frame 101, and the second limiting member 2 is provided on the vehicle door 102, and the second limiting member 2 can rotate relative to the door frame 101 with the vehicle door 102. In the inner and outer directions of the vehicle door assembly 200, the first limiting portion 11 is located on the inner side of the third limiting portion 21. At this time, the first limiting member 1 is provided on the outside of the door frame 101, and the second limiting member 2 is provided on the outside of the vehicle door 102; when the vehicle door 102 is in a closed state, at this time, the limiting structure 100 is in a locked state. When the vehicle is hit from the side, the impact force on the vehicle door assembly 200 will be transmitted to the limiting structure 100, and the first limiting portion 11 is limitedly matched with the third limiting portion 21. The third limiting portion 21 limits the first limiting portion 11 to move toward the inner side of the vehicle door assembly 200, so as to limit the second limiting member 2 from rotating toward the inner side of the vehicle door assembly 200. The movement of the vehicle door 102 toward the inner side of the vehicle door assembly 200 can be limited, that is, the vehicle door 102 can be limited to rotate toward the inner side of the vehicle door assembly 200 to reduce the intrusion amount of the vehicle door 102 toward the vehicle interior. As the vehicle door assembly 200 is deformed, the second limiting portion 12 and the fourth limiting portion 22 are limited in the second direction. The second limiting portion 12 limits the movement of the fourth limiting portion 22 in the second direction, so that the first limiting portion 11 and the third limiting portion 21 remain in a limited cooperation state, and the first limiting portion 11 and the third limiting portion 21 are avoided to a certain extent. Separation, thereby, the limiting structure 100 can be maintained in a locked state to limit the movement of the vehicle door 102 toward the inner side of the vehicle door assembly 200, so that the limiting structure 100 can maintain the integrity of the vehicle door assembly 200, effectively reducing the intrusion amount of the vehicle door 102 toward the vehicle interior after the vehicle door assembly 200 is collided sideways, which is beneficial to improving the safety of the occupants in the vehicle. When the vehicle door 102 switches from a closed state to an open state, the second limit member 2 rotates with the vehicle door 102, that is, the second limit member 2 rotates in a direction away from the first limit member 1. At this time, the third limit portion 21 is gradually separated from the first limit portion 11, and the fourth limit portion 22 is gradually separated from the second limit portion 12, until the second limit member 2 is separated from the first limit member 1. At this time, the limit structure 100 is in an unlocked state.

[0040] It can be understood that when the vehicle is hit from the side, the first limit portion 11 cooperates with the third limit portion 21 to limit the position in the first direction. It can be understood that the second side 1b of the first limit portion 11 cooperates with the third limit portion 21 to limit the position in the first direction, and the third limit portion 21 stops at the second side 1b, so that the second side 1b can limit the first limit portion 11 from moving toward the inner side of the door assembly 200.

[0041] In other examples, the first limiting member 1 is provided on the vehicle door 102, and the second limiting member 2 is provided on the door frame 101. In the inner and outer directions of the vehicle door assembly 200, the first limiting portion 11 is located on the outer side of the third limiting portion 21. At this time, the first limiting member 1 is provided in the vehicle door 102, and the second limiting member 2 is provided in the door frame 101. When the limiting structure 100 is in a locked state, the vehicle door 102 is in a closed state, the first limiting portion 11 is suitable for cooperating with the third limiting portion 21 in the upper limit position in the first direction, and the second limiting portion 12 is suitable for cooperating with the fourth limiting portion 22 in the upper limit position in the second direction. When the limiting structure 100 is in an unlocked state, the first limiting member 1 is separated from the second limiting member 2.

[0042] For example, in a side pole collision test or a side vehicle collision test, the limiting structure 100 for the door assembly 200 according to the embodiment of the present application can improve the side collision performance of the door assembly 200 (such as the side collision performance of the vehicle), effectively reduce the intrusion of the door 102 toward the inside of the door assembly 200, and improve the safety of the occupants.

[0043] According to the limiting structure 100 of the embodiment of the utility model, the first limiting portion 11 is suitable for cooperating with the third limiting portion 21 in the first direction when the locking state is set. When the outer side of the door assembly 200 is hit, the first limiting portion 11 and the third limiting portion 21 can limit the movement of the door 102 toward the inside of the door assembly 200, so that the intrusion amount of the door 102 toward the inside of the door assembly 200 can be reduced, and the intrusion degree of the door 102 toward the inside due to side impact and the like can be reduced, so as to limit the movement of the door 102 toward the inside of the door assembly 200, and the second limiting portion 12 is suitable for cooperating with the fourth limiting portion 22 in the second direction, so that the movement of the door 102 toward the inside of the door assembly 200 can be limited. The second limiting portion 12 and the fourth limiting portion 22 move in the second direction so that the first limiting portion 11 and the third limiting portion 21 remain in a limiting matching state, which is beneficial to reducing the possibility of separation of the first limiting portion 11 and the third limiting portion 21 when the vehicle door 102 invades toward the vehicle door assembly 200. The first limiting portion 11 and the third limiting portion 21 can be kept in a limiting matching state, so that the limiting structure 100 can limit the movement of the vehicle door 102 toward the vehicle door assembly 200 when the vehicle door assembly 200 is impacted from the outside, which is beneficial to reducing the possibility of the vehicle door 102 invading the inside of the vehicle door assembly 200 and affecting the safety of the occupants in the vehicle, thereby improving the safety of the occupants in the vehicle.

[0044] In some embodiments, in combination Figure 2 , Figure 5 and Figure 6In the locked state, a side surface of the second limiting portion 12 facing the fourth limiting portion 22 extends in the direction from the first side surface 1a to the second side surface 1b in a direction away from the fourth limiting portion 22, so that the second limiting portion 12 can avoid a certain space so that the fourth limiting portion 22 can smoothly cooperate with the second limiting portion 12, and the side surface of the second limiting portion 12 used for cooperating with the fourth limiting portion 22 has a certain guiding effect, which is conducive to reducing the interference between the second limiting portion 12 and the fourth limiting portion 22 when the limiting structure 100 switches from the unlocked state to the locked state, thereby reducing or avoiding the influence of the limiting structure 100 on the opening or closing of the vehicle door 102; and / or, In the locked state, a side surface of the second limiting portion 12 facing the third limiting portion 21 extends in the direction from the first side surface 1a to the second side surface 1b in a direction away from the third limiting portion 21, so that the distance between the second limiting portion 12 and the third limiting portion 21 gradually increases in the direction from the first side surface 1a to the second side surface 1b, so that the second limiting portion 12 can avoid a certain space to facilitate the third limiting portion 21 to cooperate with the first limiting portion 11 smoothly, which is beneficial to reduce the interference between the second limiting portion 12 and the third limiting portion 21 when the limiting structure 100 switches from the unlocked state to the locked state, thereby reducing or avoiding the influence of the limiting structure 100 on the opening or closing of the vehicle door 102.

[0045] In the description of the embodiments of the present application, the term "and / or" is only a description of the association relationship of the associated objects, indicating that there may be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0046] It can be understood that, in the locked state, a side surface of the second limiting portion 12 facing the fourth limiting portion 22 extends in the direction from the first side surface 1a to the second side surface 1b along a direction away from the fourth limiting portion 22, so that the distance between the second limiting portion 12 and the fourth limiting portion 22 can gradually increase during the process of switching the limiting structure 100 from the locked state to the unlocked state.

[0047] In some embodiments, in the locked state, the minimum spacing x between the second limiting portion 12 and the fourth limiting portion 22 is 4mm≤x≤8mm, so that there is a suitable distance between the second limiting portion 12 and the fourth limiting portion 22, which is conducive to the compact fit between the first limiting member 1 and the second limiting member 2. Secondly, when the limiting structure 100 switches between the locked state and the unlocked state, the interference between the second limiting structure 100 and the fourth limiting structure 100 can be reduced to reduce or avoid the influence of the limiting structure 100 on the opening or closing of the door 102, thereby ensuring the normal opening and closing of the door 102. Optionally, the minimum spacing x between the second limiting portion 12 and the fourth limiting portion 22 can be 4mm, 5mm, 5.5mm, 6mm, 6.5mm, 7mm, or 8mm, etc.

[0048] In some embodiments, in combination Figure 2 , there is at least one first limiting portion 11 and at least one third limiting portion 21 respectively, and there are multiple second limiting portions 12 and at least one fourth limiting portion 22 respectively. At least one first limiting portion 11 corresponds to at least two second limiting portions 12 arranged at intervals, and at least one third limiting portion 21 corresponds to at least two fourth limiting portions 22 respectively arranged on the opposite sides of the third limiting portion 21, and at least part of the at least one first limiting portion 11 is located between two adjacent second limiting portions 12. Therefore, for the at least one first limiting portion 11, in the locked state, the first limiting portion 11 cooperates with the third limiting portion 21 in the upper limit position in the first direction, one of the second limiting portions 12 adjacent to the first limiting portion 11 cooperates with at least one fourth limiting portion 22 located on one of the two opposite sides of the third limiting portion 21 in the upper limit position in the second direction, and another second limiting portion 12 adjacent to the first limiting portion 11 cooperates with at least one fourth limiting portion 22 located on the other side of the two opposite sides of the third limiting portion 21 in the upper limit position in the second direction, so as to facilitate the realization of the locked state, At least two fourth limiting portions 22 are limitedly matched with the corresponding second limiting portions 12, and at least one first limiting portion 11 is limitedly matched with the corresponding third limiting portion 21, so that the limiting effect of the first limiting member 1 and the second limiting member 2 in the second direction and the first direction can be improved, that is, the first limiting portion 11 and the third limiting portion 21 can be better maintained in a limited matching state, thereby improving the bearing capacity of the limiting structure 100, and better limiting the movement of the vehicle door 102 toward the inner side of the vehicle door assembly 200, so as to reduce the intrusion of the vehicle door 102 toward the inner side of the vehicle door assembly 200.

[0049] For example, in Figure 2 and Figure 5In the example, there is one third limiting portion 21, and the second end 21b of the third limiting portion 21 is connected to two fourth limiting portions 22, the two fourth limiting portions 22 are arranged in sequence along the third direction, and the two fourth limiting portions 22 respectively protrude from the third limiting portion 21 in a direction away from each other, so that the two fourth limiting portions 22 respectively correspond to the two second limiting portions 12, and the second side surface 1b of the first limiting portion 11 is provided with two second limiting portions 12, and the two second limiting portions 12 are spaced apart along the third direction. In the locked state, the third limiting portion 21 is located between the two second limiting portions 12, and the third limiting portion 21 is spaced apart from the two second limiting portions 12 respectively, and the fourth limiting portion 22 is spaced apart from the corresponding second limiting portions 12 in the second direction.

[0050] Among them, at least part of the first limiting portion 11 is located between the two second limiting portions 12, so that the above-mentioned part of the first limiting portion 11 can connect the two second limiting portions 12, which can improve the structural strength of the two second limiting portions 12, so that the second limiting portion 12 and the fourth limiting portion 22 can withstand a larger side impact force and keep the first limiting portion 11 and the third limiting portion 21 in a limited matching state.

[0051] For another example, there are multiple third limiting portions 21 and multiple first limiting portions 11, and multiple third limiting portions 21 are arranged in sequence along the third direction. The second end 21b of each third limiting portion 21 is connected to two fourth limiting portions 22, and the two fourth limiting portions 22 are arranged opposite to each other in the third direction. The second side surface 1b of the first limiting portion 11 is provided with multiple second limiting portions 12, and the multiple second limiting portions 12 are arranged at intervals along the third direction. In the locked state, each third limiting portion 21 is located between two adjacent second limiting portions 12, and the third limiting portion 21 is spaced apart from the two adjacent second limiting portions 12, and each fourth limiting portion 22 is spaced apart from a corresponding second limiting portion 12 in the second direction; wherein, multiple first limiting portions 11 can be spaced apart or connected (for example, multiple first limiting portions 11 are an integral part). Therefore, when the vehicle is hit from the side, multiple fourth limiting parts 22 are respectively limited and matched with the corresponding second limiting parts 12, which can improve the limiting and matching ability between the first limiting part 1 and the second limiting part 2, that is, it can reduce the intrusion amount of the door 102 toward the inside of the door assembly 200, thereby improving the safety of the passengers in the vehicle.

[0052] Of course, in other examples, when there are multiple second limiting portions 21, each third limiting portion 21 can also be connected to three or more fourth limiting portions 22; or, when there are multiple second limiting portions 21, at least one of the multiple second limiting portions 21 is connected to multiple fourth connecting portions 22, and each of the remaining second limiting portions 21 is connected to one fourth limiting portion 22. In addition, in some other embodiments, the first limiting portion 11, the second limiting portion 12, the third limiting portion 21 and the fourth limiting portion 22 are each one.

[0053] Optionally, part of the first limiting portion 11 is located between the two second limiting portions 12, so that the above-mentioned part of the first limiting portion 11 and the two second limiting portions 12 define a limiting groove 1c. When in the locked state, the third limiting portion 21 can be located in the limiting groove 1c, and the third limiting portion 21 is suitable for limiting cooperation with the first limiting portion 11. The first limiting portion 11 can be constructed to include a groove bottom wall of the limiting groove 1c.

[0054] Optionally, the second limiting member 2 includes a fixing portion 23 , which is disposed at the first end 21 a of the third limiting portion 21 , and the fixing portion 23 is connected to the other of the door frame 101 and the vehicle door 102 .

[0055] In some embodiments, the second direction is perpendicular to the first direction, and the relative direction of the first side surface 1a and the second side surface 1b is perpendicular to the extension direction of the third limiting portion 21, so that the first limiting portion 11 can better limit and cooperate with the third limiting portion 21. For example, the second side surface 1b has a larger contact area and stops and cooperates with the third limiting portion 21, which is beneficial to uniform force between the contacting parts of the first limiting portion 11 and the third limiting portion 21, and can improve the bearing capacity of the first limiting portion 11 and the third limiting portion 21.

[0056] Optionally, the first direction, the second direction and the third direction are perpendicular to each other, so that the direction in which the first side surface 1a and the second side surface 1b are relatively set (for example, the extension direction of the second limiting portion 12), the extension direction of the third limiting portion 21 and the direction in which the fourth limiting portion 22 protrudes from the third limiting portion 21 are perpendicular to each other, so that the first limiting portion 11 can have a larger contact area and cooperate with the third limiting portion 21, which can improve the bearing capacity of the first limiting portion 11 and the third limiting portion 21, and the fourth limiting portion 22 can better contact with the second limiting portion 12 to ensure that the limiting cooperation between the fourth limiting portion 22 and the second limiting portion 12 is reliable.

[0057] Optionally, in the second direction, a side surface of the second limiting portion 12 facing the fourth limiting portion 22 is parallel to a side surface of the fourth limiting portion 22 facing the second limiting portion 12, so that when the second limiting portion 12 and the fourth limiting portion 22 are limitedly matched, the mutually matching surfaces of the second limiting portion 12 and the fourth limiting portion 22 have a larger contact film area, which can make the force between the second limiting portion 12 and the fourth limiting portion 22 uniform, which is beneficial to improving the bearing capacity between the second limiting portion 12 and the fourth limiting portion 22, that is, the second limiting portion 12 and the fourth limiting portion 22 can withstand a larger side impact and remain in a limited matching state.

[0058] The vehicle door assembly 200 according to the second aspect embodiment of the utility model includes a door frame 101, a vehicle door 102 and a limiting structure 100 according to the first aspect embodiment of the utility model. The vehicle door 102 is movably connected to the door frame 101 to realize the opening and closing of the vehicle door 102. The first limiting member 1 is provided at one of the door frame 101 and the vehicle door 102, and the second limiting member 2 is provided at the other of the door frame 101 and the vehicle door 102.

[0059] According to the vehicle door assembly 200 of the embodiment of the present invention, the ability of the vehicle door assembly 200 to withstand side impact can be improved by adopting the above-mentioned limiting structure 100.

[0060] Optionally, the door 102 in the door assembly 200 may be a front door or a rear door of the vehicle, and the A-pillar, B-pillar or C-pillar of the vehicle may be a part of the door frame 101. For example, when the limiting structure 100 is provided on the front door, one of the first limiting member 1 and the second limiting member 2 may be provided on the B-pillar, and the other may be provided on the front door; when the limiting structure 100 is provided on the rear door, one of the first limiting member 1 and the second limiting member 2 may be provided on the C-pillar, and the other may be provided on the rear door. Of course, there may be multiple limiting structures 100, and the multiple limiting structures 100 are provided on the front door and the rear door of the vehicle respectively.

[0061] In some embodiments, in combination Figure 1 and Figure 2 The first limiting member 1 is arranged on the outer side of the door frame 101, and the second limiting member 2 is arranged on the outer side of the vehicle door 102, that is, the limiting structure 100 is located on the outer side of the vehicle door assembly 200. Therefore, when the outer side of the vehicle door assembly 200 is impacted, the first limiting portion 11 and the third limiting portion 21 cooperate to limit the vehicle door 102 in the first direction, and the impact force exerted on the vehicle door 102 is transmitted to the door frame 101 through the limiting structure 100, and the limiting structure 100 makes the vehicle door assembly 200 a whole to jointly bear the impact force, so that the vehicle door assembly 200 can withstand a larger side impact force to reduce the intrusion of the vehicle door 102 into the vehicle.

[0062] Optionally, the first position-limiting member 1 is disposed on the inner side of the vehicle door 102 , and the second position-limiting member 2 is disposed on the inner side of the door frame 101 .

Secondly, the limit structure 100 and the pivot connection structure 103 can cooperate with each other, so that the vehicle door assembly 200 can withstand greater side impact force to reduce the intrusion of the vehicle door 102 into the vehicle.

[0064] For example, combined with Figure 1 and Figure 3 , one end of the door 102 (eg Figure 3 The vehicle door 102 in the figure has two spaced-apart pivot connection structures 103, the two pivot connection structures 103 are respectively connected to the door frame 101, the pivot connection structure 103 has a pivot axis, and the other end of the vehicle door 102 can rotate relative to the pivot axis. The vehicle door assembly 200 also includes a limiting structure 100, the second limiting member 2 is arranged on the outside of the other end of the vehicle door 102 (for example, the rear side of the vehicle door 102 in the figure), and the first limiting member 1 is arranged on the outside of the door frame 101 and cooperates with the second limiting member 2.

[0065] In some embodiments, in combination Figure 1 and Figure 3 The other end of the vehicle door 102 is also provided with a door lock structure 104, which is spaced above the second stopper 2. Thus, the door lock structure 104 cooperates with the stopper structure 100 to improve the vehicle door assembly 200 from withstanding a larger side impact force, and the door lock structure 104 and the stopper structure 100 can better limit the movement of the vehicle door 102 toward the inside of the vehicle door 102, so as to reduce the intrusion of the vehicle door 102 toward the vehicle interior and improve the safety of the passengers.

[0066] For example, combined with Figure 1 and Figure 3 The vehicle door assembly 200 includes two pivot connection structures 103, a door lock structure 104 and a limiting structure 100. The two pivot connection structures 103 are arranged on the front side of the vehicle door 102, and the two pivot connection structures 103 are arranged at intervals in the up and down directions. The door lock structure 104 and the limiting structure 100 are arranged on the rear side of the vehicle door 102, and the limiting structure 100 is located on the lower side of the door lock structure 104.

[0067] Optionally, combined Figure 1 and Figure 3 The door 102 has an upper end and a lower end, the distance between the upper end and the lower end of the door 102 in the vertical direction is L1, the distance between the limiting structure 100 and the upper end of the door 102 in the vertical direction is L2, 3 / 5≤L2 / L1≤4 / 5 and the limiting structure 100 is located below the door lock structure 104, so that the limiting structure 100 is in a suitable position, and can better cooperate with the door lock structure 104 to improve the bearing capacity of the door assembly 200 to withstand the side impact force, and secondly, the limiting structure 100 is located at the lower side of the door 102, which can prevent the occupant from contacting the limiting structure 100 and causing injuries when the occupant gets off the vehicle from the door 102 to a certain extent. Optionally, L2 / L1 can be 3 / 5, 2 / 3, or 4 / 5, etc.
