[0028] Reference below Figure 1 and Figure 2 A vehicle door assembly 100 according to an embodiment of the present invention is described.

[0029] like Figure 1 and Figure 2 As shown, a vehicle door assembly 100 according to an embodiment of the present invention includes a front door assembly 1 and a rear door assembly 2 .

[0030] Specifically, such as Figure 1 and Figure 2As shown, a vehicle door assembly 100 is used in a vehicle. The front door assembly 1 includes a front door inner panel 11 and a front door outer panel 12, defining a front cavity 13 therebetween. The rear door assembly 2 is located on the same side of the vehicle as the front door assembly 1, and is located behind the front door assembly 1. There is no B-pillar between the front and rear door assemblies 1 and 2. The rear door assembly 2 includes a rear door inner panel 21 and a rear door outer panel 22, defining a rear cavity 23 therebetween. A front B-pillar 14 is provided at the rear end of the front cavity 13, and / or a rear B-pillar 24 is provided at the front end of the rear cavity 23.

[0031] It can be understood that the front door assembly 1 and the rear door assembly 2 are arranged on the side of the vehicle and are opposite to the positions of the front passengers and the rear passengers respectively. There is no B-pillar between the front door assembly 1 and the rear door assembly 2, which can effectively increase the space for passengers to move inside the vehicle, and at the same time improve the convenience of passengers getting on and off the vehicle, thereby improving the comfort and experience of the passengers.

[0032] Among them, the front door inner panel 11 is arranged on the side of the front door assembly 1 close to the interior space of the vehicle, and the front door outer panel 12 is arranged on the side of the front door assembly 1 away from the interior space of the vehicle. By dividing the front door assembly 1 into the front door inner panel 11 and the front door outer panel 12, it is convenient to produce and process the front door inner panel 11 and the front door outer panel 12 separately and then assemble them into the front door assembly 1, which can reduce the processing difficulty of the front door assembly 1 to improve production efficiency, and facilitate the increase of the space size of the front cavity 13, thereby facilitating the provision of sufficient setting space for the front B-pillar 14, so that the front B-pillar 14 can be hidden in the front door assembly 1, which is beneficial to improving the appearance of the door assembly 100 and the vehicle.

[0033] Similarly, the rear door inner panel 21 is arranged on the side of the rear door assembly 2 close to the vehicle interior space, and the rear door outer panel 22 is arranged on the side of the rear door assembly 2 away from the vehicle interior space. By dividing the rear door assembly 2 into the rear door inner panel 21 and the rear door outer panel 22, it is convenient to produce and process the rear door inner panel 21 and the rear door outer panel 22 separately and then assemble them into the rear door assembly 2. This can reduce the processing difficulty of the rear door assembly 2 to improve production efficiency, and it is convenient to increase the space size of the rear cavity 23, thereby providing sufficient setting space for the rear B-pillar 24, so that the rear B-pillar 24 can be hidden in the rear door assembly 2, which is beneficial to improving the appearance of the door assembly 100 and the vehicle.

[0034] By disposing the front B-pillar 14 at the rear end of the front cavity 13 and / or the rear B-pillar 24 at the front end of the rear cavity 23, the structural strength of the door assembly 100 can be enhanced, effectively compensating for the strength loss that may be caused by the absence of a B-pillar between the front door assembly 1 and the rear door assembly 2. The collision resistance of the door assembly 100 can also be enhanced. When a side collision occurs, the front B-pillar 14 and / or the rear B-pillar 24 can absorb and cushion part of the impact force, thereby enhancing the impact resistance of the vehicle's side, protecting the safety of the vehicle's occupants and reducing injuries, thereby improving the overall safety performance of the vehicle.

[0035] According to the vehicle door assembly 100 of the embodiment of the present invention, by eliminating the B-pillar between the front door assembly 1 and the rear door assembly 2, the space for passengers to move around in the vehicle is effectively increased and the convenience of passengers getting on and off the vehicle is improved, thereby improving the comfort and experience of the passengers. At the same time, the front B-pillar 14 is provided at the rear end of the front cavity 13 within the front door assembly 1, and / or the rear B-pillar 24 is provided at the front end of the rear cavity 23 within the rear door assembly 2. This can enhance the structural strength and collision resistance of the vehicle door assembly 100, thereby enhancing the impact resistance and collision resistance of the vehicle side, effectively protecting the safety of the passengers in the event of a side collision, and thus improving the overall safety performance of the vehicle.

[0036] In some embodiments, the front door assembly 1 and the rear door assembly 2 may be designed as side-by-side doors, with the side of the front door assembly 1 remote from the rear door assembly 2 being rotatably connected to the vehicle body, and the side of the rear door assembly 2 remote from the front door assembly 1 being rotatably connected to the vehicle body. A front B-pillar 14 and a rear B-pillar 24 are mounted on the respective sides of the front door assembly 1 and the rear door assembly 2, respectively, with the front B-pillar 14 being located at the rear end of the front cavity 13 and the rear B-pillar 24 being located at the front end of the rear cavity 23.

[0037] In this manner, the front B-pillar 14 and the rear B-pillar 24 are directly mounted within the front door assembly 1 and the rear door assembly 2, respectively, and can move relative to the vehicle body with the front door assembly 1 and the rear door assembly 2. This allows the front B-pillar 14 and the rear B-pillar 24 to be concealed, giving the side of the vehicle a clean and smooth appearance when the door assembly 100 is opened. Furthermore, the entire side space is larger, and by opening the front door assembly 1 and the rear door assembly 2 simultaneously, it is convenient for passengers to enter and exit the vehicle interior and to load larger items. Furthermore, when both doors are closed, the front B-pillar 14 and the rear B-pillar 24 mounted on the front door assembly 1 and the rear door assembly 2 can move to the side of the vehicle and extend vertically to enhance the vehicle's resistance to side collisions. Furthermore, by providing the front B-pillar 14 and the rear B-pillar 24 simultaneously, the front door assembly 1 and the rear door assembly 2 can jointly support the vehicle's side structure to increase resistance to pressure, thereby further enhancing the vehicle's side impact resistance and safety performance.

[0038] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, a front B-pillar 14 is provided at the rear end of the front cavity 13. The front door inner panel 11 includes a main body of the front door inner panel 11 and a rear section of the front door inner panel 11, which are separately provided. One end of the rear section of the front door inner panel 11 is welded to the rear end of the main body of the front door inner panel 11, and the other end is connected to the rear end of the front door outer panel 12. By separating the front door inner panel 11, it is easier to produce and process the main body of the front door inner panel 11 and the rear section of the front door inner panel 11 separately, and then assemble them into the front door inner panel 11. This can solve the problem that the front door assembly 1 is difficult to form due to its deep depth, reduce the processing difficulty of the front door inner panel 11 and the front door assembly 1, and thus improve production efficiency.

[0039] The main body and rear section of the front door inner panel 11 can be formed using a stamping process, which offers high production efficiency and dimensional accuracy, ensuring rapid and accurate production of the front door inner panel 11. This process also facilitates welding, increasing production flexibility for the front door inner panel 11 to meet diverse production needs. Separately stamping the main body and rear section of the front door inner panel 11 and then welding them together effectively reduces the draft angle in the thickness direction of the door assembly 100, thereby increasing the size of the front cavity 13 and improving the space utilization of the door assembly 100 in the thickness direction.

[0040] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, a front B-pillar 14 is provided at the rear end of the front cavity 13. The front B-pillar 14 is connected to the front door inner panel 11, which can ensure the stability of the front B-pillar 14 in the front cavity 13, thereby ensuring the structural strength of the front door assembly 1, and further ensuring the impact resistance and anti-collision performance of the vehicle side.

[0041] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the front B-pillar 14 includes a front B-pillar body 141 and a front bracket 142. The front bracket 142 is welded to the front B-pillar body 141. The front bracket 142 is located on the side of the front B-pillar body 141 near the front door inner panel 11 and is connected to the front door inner panel 11 via fasteners. The welded front bracket 142 and front B-pillar body 141 ensure the connection strength, forming the front bracket 142 and front B-pillar body 141 as a single unit, thereby ensuring the structural stability of the front B-pillar 14. The front B-pillar body 141 is cylindrical and extends in the vertical direction of the vehicle. The provision of the front bracket 142 facilitates the fixed connection between the front B-pillar body 141 and the front door inner panel 11, improving assembly efficiency. It also ensures the stability of the connection between the front B-pillar 14 and the front door inner panel 11, thereby maintaining the structural strength of the front door assembly 1 and, in turn, the impact resistance and collision resistance of the vehicle side.

[0042] Specifically, if Figure 1 In the example shown, the front bracket 142 is fixedly connected to the front door inner panel 11 via a first fastener 16 .

[0043] Multiple front brackets 142 are spaced apart vertically, each having a front mounting hole 143 for connection to the front door inner panel 11. Alternatively, the front brackets 142 extend vertically and are provided with multiple front mounting holes 143, spaced vertically apart. This allows the front B-pillar 14 to be fixedly connected to the front door inner panel 11 at multiple locations, further enhancing the connection stability between the front B-pillar 14 and the front door inner panel 11, thereby improving the structural strength of the front door assembly 1 and, in turn, enhancing the impact resistance and collision avoidance of the vehicle side.

[0044] In some embodiments, the front B-pillar 14 has a hollow structure. Specifically, a vertically extending front cavity structure is provided within the front B-pillar 14. This not only improves the impact resistance of the front B-pillar 14, but also more effectively absorbs and disperses the impact force when a collision occurs, thereby better protecting the safety of the occupants. Furthermore, the front cavity structure facilitates a lightweight design of the front B-pillar 14. While maintaining sufficient structural strength, it can significantly reduce the mass of the front B-pillar 14 and the front door assembly 1, thereby reducing the production cost and operating energy consumption of the vehicle.

[0045] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, a rear B-pillar 24 is provided at the front end of the rear cavity 23. The rear door inner panel 21 comprises a main body of the rear door inner panel 21 and a front section of the rear door inner panel 21, which are separately provided. One end of the front section of the rear door inner panel 21 is welded to the front end of the main body of the rear door inner panel 21, and the other end is connected to the front end of the rear door outer panel 22. By providing a separate rear door inner panel 21, it is easier to manufacture the main body of the rear door inner panel 21 and the front section of the rear door inner panel 21 separately, and then assemble them into the rear door inner panel 21. This solves the problem of the rear door assembly 2 being difficult to form due to its depth, reduces the difficulty in manufacturing the rear door inner panel 21 and the rear door assembly 2, and thus improves production efficiency.

[0046] The main body and front section of the rear door inner panel 21 can be formed using a stamping process, which offers high production efficiency and dimensional accuracy, ensuring rapid and accurate production of the rear door inner panel 21. This process also facilitates welding, increasing production flexibility for the rear door inner panel 21 to meet diverse production needs. Separately stamping the main body and front section of the rear door inner panel 21 and then welding them together effectively reduces the draft angle in the thickness direction of the door assembly 100, thereby increasing the size of the rear cavity 23 and improving the space utilization of the door assembly 100 in the thickness direction.

[0047] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, a rear B-pillar 24 is provided at the front end of the rear cavity 23, and the rear B-pillar 24 is connected to the rear door inner panel 21, which can ensure the stability of the rear B-pillar 24 in the rear cavity 23, thereby ensuring the structural strength of the rear door assembly 2, and further ensuring the impact resistance and anti-collision performance of the vehicle side.

[0048] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the rear B-pillar 24 comprises a rear B-pillar body 241 and a rear bracket 242. The rear bracket 242 is welded to the rear B-pillar body 241. The rear bracket 242 is located on the side of the rear B-pillar body 241 near the rear door inner panel 21 and is connected to the rear door inner panel 21 via fasteners. The welded rear bracket 242 and rear B-pillar body 241 ensure a strong connection, forming the rear bracket 242 and rear B-pillar body 241 as a single unit, thus ensuring the structural stability of the rear B-pillar 24. The rear B-pillar body 241 is cylindrical and extends vertically along the vehicle. The rear bracket 242 facilitates the secure connection between the rear B-pillar body 241 and the rear door inner panel 21, improving assembly efficiency. It also ensures a stable connection between the rear B-pillar 24 and the rear door inner panel 21, thereby maintaining the structural strength of the rear door assembly 2 and, in turn, ensuring the impact resistance and crashworthiness of the vehicle's side.

[0049] Specifically, if Figure 2 In the example shown, the rear bracket 242 is fixedly connected to the rear door inner panel 21 via a second fastener 26 .

[0050] Multiple rear brackets 242 are spaced apart vertically, each having a rear mounting hole 243 for connection to the rear door inner panel 21. Alternatively, the rear brackets 242 extend vertically and are provided with multiple rear mounting holes 243, spaced vertically apart. This allows the rear B-pillar 24 to be fixedly connected to the rear door inner panel 21 at multiple locations, further enhancing the connection stability between the rear B-pillar 24 and the rear door inner panel 21, thereby improving the structural strength of the rear door assembly 2 and, in turn, enhancing the impact resistance and crashworthiness of the vehicle's side.

[0051] In some embodiments, the rear B-pillar 24 has a hollow structure. Specifically, a rear cavity structure extending vertically within the rear B-pillar 24 not only improves the impact resistance of the rear B-pillar 24 but also more effectively absorbs and disperses the impact force when a collision occurs, thereby better protecting the safety of the occupants. Furthermore, the rear cavity structure facilitates a lightweight design of the rear B-pillar 24. While maintaining sufficient structural strength, it can significantly reduce the mass of the rear B-pillar 24 and the rear door assembly 2, thereby reducing the production cost and operating energy consumption of the vehicle.

[0052] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the rear end of the front door assembly 1 is provided with a first seal 15. The first seal 15 is engaged with the front door assembly 1 and is located on the side of the front door assembly 1 near the front door outer panel 12. When the front door assembly 1 and the rear door assembly 2 are closed, the first seal 15 abuts the front end of the rear door assembly 2. The first seal 15 is elastic. When the front door assembly 1 and the rear door assembly 2 are closed, the first seal 15 is squeezed and deformed by the rear door assembly 2, creating an interference fit between the front door assembly 1 and the rear door assembly 2. On the one hand, the first seal 15 provides a sealing effect, effectively preventing rainwater, dust, and other objects from entering the vehicle interior, thereby maintaining a clean and comfortable interior. It also helps to isolate external noise, improve the quietness of the vehicle interior, and provide a more comfortable riding environment for passengers. On the other hand, the first seal 15 also serves as a hand-pinch protection device, cushioning the impact of the front door assembly 1 on hands and other objects when the door is closed, thereby enhancing passenger safety.

[0053] The first sealing member 15 includes a first fixing portion 151 and a first abutting portion 152. The first fixing portion 151 is snap-connected to the front door assembly 1. The first abutting portion 152 is arc-shaped, and a first cavity is formed between the first fixing portion 151 and the first abutting portion 152. The first cavity provides space for the compression and deformation of the first abutting portion 152, allowing the first abutting portion 152 to deform under external force. When the front door assembly 1 and the rear door assembly 2 are closed, the first abutting portion 152 deforms and abuts the front end of the rear door assembly 2, causing the first sealing member 15 to be compressed, thereby ensuring a good sealing effect.

[0054] In some embodiments of the present invention, Figure 1 and Figure 2As shown, the front end of the rear door assembly 2 is provided with a second seal 25. The second seal 25 is engaged with the rear door assembly 2 and is located on the side of the rear door assembly 2 near the rear door inner panel 21. When the front door assembly 1 and the rear door assembly 2 are closed, the second seal 25 abuts the rear end of the front door assembly 1. The second seal 25 is elastic. When the front door assembly 1 and the rear door assembly 2 are closed, the second seal 25 is squeezed and deformed by the rear door assembly 2, creating an interference fit between the front door assembly 1 and the rear door assembly 2. The second seal 25 provides a sealing effect, effectively preventing rainwater, dust, and other objects from entering the vehicle interior, thereby maintaining a clean and comfortable interior. It also helps to isolate external noise, improve the quietness of the vehicle interior, and provide a more comfortable riding environment for passengers.

[0055] The second sealing member 25 includes a second fixing portion 251 and a second abutting portion 252. The second fixing portion 251 is snap-connected to the rear door assembly 2. The second abutting portion 252 is arc-shaped, and a second cavity is formed between the second fixing portion 251 and the second abutting portion 252. The second cavity provides space for the second abutting portion 252 to compress and deform, allowing the second abutting portion 252 to deform when subjected to external force. When the front door assembly 1 and the rear door assembly 2 are closed, the second abutting portion 252 deforms and abuts the front end of the rear door assembly 2, causing the second sealing member 25 to be compressed, thereby ensuring a good sealing effect.

[0056] A vehicle according to an embodiment of the present invention will be described below.

[0057] A vehicle according to an embodiment of the present invention includes: the above-mentioned door assembly 100 .

[0058] Specifically, such as Figure 1 and Figure 2 As shown, a vehicle door assembly 100 is used in a vehicle. The front door assembly 1 includes a front door inner panel 11 and a front door outer panel 12, defining a front cavity 13 therebetween. The rear door assembly 2 is located on the same side of the vehicle as the front door assembly 1, and is located behind the front door assembly 1. There is no B-pillar between the front and rear door assemblies 1 and 2. The rear door assembly 2 includes a rear door inner panel 21 and a rear door outer panel 22, defining a rear cavity 23 therebetween.

[0059] It can be understood that the front door assembly 1 and the rear door assembly 2 are arranged on the side of the vehicle and are opposite to the positions of the front passengers and the rear passengers respectively. There is no B-pillar between the front door assembly 1 and the rear door assembly 2, which can effectively increase the space for passengers to move inside the vehicle, and at the same time improve the convenience of passengers getting on and off the vehicle, thereby improving the comfort and experience of the passengers.

[0060] Among them, the front door inner panel 11 is arranged on the side of the front door assembly 1 close to the interior space of the vehicle, and the front door outer panel 12 is arranged on the side of the front door assembly 1 away from the interior space of the vehicle. By dividing the front door assembly 1 into the front door inner panel 11 and the front door outer panel 12, it is convenient to produce and process the front door inner panel 11 and the front door outer panel 12 separately and then assemble them into the front door assembly 1, which can reduce the processing difficulty of the front door assembly 1 to improve production efficiency, and facilitate the increase of the space size of the front cavity 13, thereby facilitating the provision of sufficient setting space for the front B-pillar 14, so that the front B-pillar 14 can be hidden in the front door assembly 1, which is beneficial to improving the appearance of the door assembly 100 and the vehicle.

[0061] Similarly, the rear door inner panel 21 is arranged on the side of the rear door assembly 2 close to the vehicle interior space, and the rear door outer panel 22 is arranged on the side of the rear door assembly 2 away from the vehicle interior space. By dividing the rear door assembly 2 into the rear door inner panel 21 and the rear door outer panel 22, it is convenient to produce and process the rear door inner panel 21 and the rear door outer panel 22 separately and then assemble them into the rear door assembly 2. This can reduce the processing difficulty of the rear door assembly 2 to improve production efficiency, and it is convenient to increase the space size of the rear cavity 23, thereby providing sufficient setting space for the rear B-pillar 24, so that the rear B-pillar 24 can be hidden in the rear door assembly 2, which is beneficial to improving the appearance of the door assembly 100 and the vehicle.

[0062] By disposing the front B-pillar 14 at the rear end of the front cavity 13 and / or the rear B-pillar 24 at the front end of the rear cavity 23, the structural strength of the door assembly 100 can be enhanced, effectively compensating for the strength loss that may be caused by the absence of a B-pillar between the front door assembly 1 and the rear door assembly 2. The collision resistance of the door assembly 100 can also be enhanced. When a side collision occurs, the front B-pillar 14 and / or the rear B-pillar 24 can absorb and cushion part of the impact force, thereby protecting the safety of the occupants and reducing injuries to the occupants. This can enhance the impact resistance of the vehicle's side and further improve the overall safety performance of the vehicle.

[0063] According to the vehicle of the embodiment of the present invention, by eliminating the B-pillar between the front door assembly 1 and the rear door assembly 2, the space for passengers to move around in the vehicle is effectively increased and the convenience of passengers getting on and off the vehicle is improved, thereby improving the comfort and experience of the passengers. At the same time, the front B-pillar 14 is provided at the rear end of the front cavity 13 within the front door assembly 1, and / or the rear B-pillar 24 is provided at the front end of the rear cavity 23 within the rear door assembly 2. This can enhance the structural strength and collision resistance of the door assembly 100, thereby enhancing the impact resistance and collision resistance of the side of the vehicle, effectively protecting the safety of the passengers in the event of a side collision, and thus improving the overall safety performance of the vehicle.
