Description

Technical Field

[0001] This application relates to the field of automotive technology, and more particularly to a door structure and a vehicle. Background Technology

[0002] As people's car usage scenarios become increasingly diverse, consumers' demands for vehicle convenience continue to upgrade. Vehicles not only need to meet daily commuting needs but also adapt to various scenarios such as family travel, transporting large items, and use by special groups. This places higher demands on the space utilization and ease of passage of the vehicle body structure. The suicide door structure, because the front and rear doors can open forward and backward respectively, reduces the space occupied when opening compared to traditional side doors. Its application in passenger cars and commercial vehicles is gradually increasing, becoming an important design direction for improving usability. In the field of automotive design, the suicide door form has attracted attention due to its large opening angle and convenient passenger entry and exit. Traditional suicide door vehicles usually have a B-pillar between the front and rear doors. This B-pillar plays a role in supporting the roof, improving body rigidity, and side collision safety. However, the presence of the B-pillar also objectively divides the door opening space, limiting the continuity and overall width of the door opening. In addition, simply eliminating the B-pillar would cause the sealing structure between the door and the body to lose support, leading to problems with waterproofing, dustproofing, and sound insulation performance, affecting the comfort, safety, and durability of the vehicle.

The device may be oriented in other ways (rotated 90° or otherwise), and the spatial relative descriptive terms used in this application can be interpreted accordingly.

[0030] The following description, in conjunction with the accompanying drawings, illustrates a door structure provided in this application. Please refer to the attached drawings. Figures 1-3The door structure includes a door frame 1, a rear door 2, a front door 3, and a sealing structure. The rear door 2 is rotatably connected to one end of the door frame 1. The front door 3 is rotatably connected to the other end of the door frame 1, forming a double-door structure with the rear door 2, achieving a pillarless effect and creating a wide and continuous doorway, which is beneficial to improving the space utilization of the vehicle. The sealing component 4 is set between the front door 3 and the rear door 2. When the front door 3 and the rear door 2 are rotated to cooperate with the door frame 1, they are sealed together by the sealing component 4. The sealing component 4 forms a sealed isolation cavity 5 between the front door 3 and the rear door 2, which can effectively seal the gap between the front door 3 and the rear door 2. By setting the sealed isolation cavity 5, dust, noise and heat from outside the vehicle can be effectively isolated, improving the comfort and cleanliness of the vehicle interior.

[0031] In a possible implementation, the rear door body 2 includes a rear door side panel 21, a rear door inner panel 23, and a rear door outer panel 22, with the rear door inner panel 23 and the rear door outer panel 22 fixedly connected by the rear door side panel 21; in some embodiments, the rear door outer panel 22 and the rear door side panel 21 are connected by welding; preferably, the rear door side panel 21 and the rear door outer panel 22 are connected by an edge-sealing structure, which helps to improve the aesthetics of the connection position between the rear door side panel 21 and the rear door outer panel 22.

[0032] Specifically, the rear door side panel 21 is provided with a first mounting part, which can be used to install the sealing component 4; the first mounting part can be a snap-fit ​​groove, and the sealing component 4 is detachably connected to the snap-fit ​​groove, thereby improving the convenience of installation and maintenance of the sealing component 4.

[0033] Specifically, the rear door inner panel 23 and the rear door side panel 21 can be a one-piece molded structure, which can effectively disperse stress, improve the overall structural strength of the door, and the one-piece molded structure can more effectively block wind noise and external noise, which helps to improve the door's sealing and sound insulation, and enhance driving comfort.

[0034] In a possible implementation, the front door body 3 includes a front door side panel 31, a front door inner panel 33, and a front door outer panel 32. The front door inner panel 33 and the front door rear panel are connected through the front door side panel 31. The front door side panel 31 and the front door inner panel 33 are connected by welding. After the front door side panel 31 and the front door inner panel 33 are connected, a first welding surface is formed. The first welding surface can be used to provide an installation position for the sealing assembly 4. Specifically, the width of the first welding surface can be 14mm to ensure that the sealing assembly 4 can be stably installed.

[0035] Specifically, the front door side panel 31 and the front door outer panel 32 are connected by welding. After the front door side panel 31 and the front door outer panel 32 are connected, a second welding surface is formed. It can be understood that the second welding surface is the overlapping surface of the front door side panel 31 and the front door outer panel 32. The width of the second welding surface can be 8mm, which can ensure the structural strength of the second welding surface and effectively compensate for the loss of body rigidity due to the removal of the B-pillar.

[0036] In a possible implementation, when the front door body 3 and the rear door body 2 are rotated to engage with the door frame 1, the sealing assembly 4 seals the front door side panel 31 and the rear door side panel 21, and the front door outer panel 32 and the rear door outer panel 22 are flush to form the exterior surface of the door structure. In this way, the sealing assembly 4 can be hidden on the exterior surface through the engagement of the front door outer panel 32 and the front door rear panel, ensuring effective sealing of the front door body 3 and the rear door body 2 while improving the aesthetics of the door. Understandably, this also prevents airflow from entering the cavity 6, thereby reducing the airflow into the cavity 6 and lowering the noise generated by the airflow within the cavity.

[0037] In a possible implementation, the sealing assembly 4 includes a first sealing structure 41 and a second sealing structure 42. The sealing assembly 4 is disposed in one of the front door body 3 and the rear door body 2. The first sealing structure 41 and the second sealing structure 42 are spaced apart, which can form a double seal between the front door body 3 and the rear door body 2, which is beneficial to improving the sealing performance of the sealing assembly 4, thereby improving the sound insulation, dustproof and waterproof effect of the door structure.

[0038] Specifically, when the front door body 3 and the rear door body 2 are rotated to cooperate with the door frame body 1, a sealed isolation cavity 5 can be formed between the first sealing structure 41 and the second sealing structure 42. Understandably, the sealed isolation cavity 5 is filled with air, and the sealed isolation cavity 5 can effectively isolate external noise from the vehicle and improve the vehicle's quietness performance.

[0039] Specifically, the first sealing structure 41 and the second sealing structure 42 can seal and connect the rear door body 2 and the front door side panel 31, forming a spaced-apart sealed isolation cavity 5 and cavity 6 between the front door side panel 31 and the rear door body 2. Cavity 6 is adjacent to the exterior surface. Specifically, cavity 6 can be a cavity with an open structure, which can isolate some noise and heat; the sealed isolation cavity 5 and cavity 6 can work together to improve the sealing effect of the door structure, and cavity 6 can block some rainwater and dust from entering the sealed isolation cavity 5, thereby preventing rainwater and dust from entering the vehicle interior, which is beneficial to improving the protection effect of the vehicle interior.

[0040] Specifically, the width of the sealing isolation cavity 5 is greater than 11mm. This width is understood to be the distance between the front door side panel 31 and the rear door side panel 21 when the front door body 3 and the rear door body 2 are in the mated state. Controlling the width of the sealing isolation cavity 5 within this range prevents motion interference between the sealing assembly 4 and the door body during the rotation of the front door body 3 and the rear door body 2. It is understood that the width of the sealing isolation cavity 5 can be adjusted according to the structural requirements of the sealing isolation cavity 5 in actual applications. Increasing the size of the sealing isolation cavity 5 within an appropriate range can improve its sound and heat insulation effects.

[0041] In some embodiments, the first sealing structure 41 is disposed on the rear door side panel 21, and the second sealing structure 42 is disposed on the front door side panel 31, which avoids installing multiple sealing structures on the same door body and helps to reduce vibration noise when the door is closed.

[0042] Specifically, when the front door body 3 and the rear door body 2 are rotated to cooperate with the door frame body 1, the first sealing structure 41 is sealed to the front door side panel 31, and the second sealing structure 42 is sealed to the rear door side panel 21. Specifically, the first sealing structure 41 is located in the middle of the rear door side panel 21, and the second sealing structure 42 is located near the front door inner panel 33. The first sealing structure 41 and the second sealing structure 42 form a sealed isolation cavity 5 between the front door side panel 31 and the rear door side panel 21. A cavity 6 near the outer surface is formed between the first sealing structure 41, the front door side panel 31 and the rear door side panel 21. It can be understood that the sealed isolation cavity 5 and the cavity 6 are separated by the first sealing structure 41, which can form multiple seals between the front door body 3 and the rear door body 2.

[0043] In a possible implementation, the first sealing structure 41 is partially disposed between the rear door body 2 and the door frame 1, and the second sealing structure 42 is partially disposed between the front door body 3 and the door frame 1. When the front door body 3 and the rear door body 2 are rotated to engage with the door frame 1, the first sealing structure 41 can seal the gap between the rear door body 2 and the door frame 1, and the second sealing structure can seal the gap between the front door body 3 and the door frame 1. At the same time, the first sealing structure 41 and the second sealing structure 42 can seal the gap between the front door body 3 and the rear door body 2, forming a continuous sealing effect in the door structure, which helps to simplify the structure of the sealing assembly 4.

[0044] Specifically, the first sealing structure 41 is provided with a flow guiding structure, which allows rainwater entering the cavity 6 to be discharged along the flow guiding structure, avoiding water accumulation in the cavity 6, and effectively preventing external rainwater from entering the sealed isolation cavity 5.

[0045] In a possible implementation, the door structure also includes a third sealing structure disposed on the front door outer panel 32. When the front door body 3 and the rear door body 2 are rotated to cooperate with the door frame 1, the third sealing structure seals the front door outer panel 32 and the rear door outer panel 22, thereby sealing the cavity 6 and preventing airflow from flowing into the cavity 6, thus reducing the airflow into the cavity 6 and reducing the noise generated by the airflow in the cavity 6. Furthermore, the third sealing structure, the front door outer panel 32, and the rear door outer panel 22 can be connected to form an exterior surface, making the outer surface of the door structure smoother and helping to reduce wind resistance when the vehicle is in motion.

[0046] In a possible implementation, the front door side panel 31 is provided with a boss structure 7 and a recess 8. The recess 8 is located near the outer surface. The first sealing structure 41 abuts against the boss structure 7 and avoids each other. Understandably, the first sealing structure 41 is protruding from the rear door side panel 21. During the connection process between the rear door body 2 and the front door body 3, the first sealing structure 41 can avoid each other with the recess 8, thereby avoiding movement with the front door outer panel 32. This allows the first sealing structure 41 to move smoothly to the position where it abuts against the boss structure 7, avoiding interference of the first sealing structure 41 with the opening and closing process of the rear door body 2, which would cause jamming during the closing process. At the same time, it can reduce structural wear and help improve the service life of the door structure.

[0047] Specifically, the boss structure 7, the recessed part 8 and the front door side panel 31 are integrally formed, ensuring the alignment accuracy between the boss structure 7 and the first sealing structure 41, and avoiding assembly tolerances that would prevent the boss structure 7 and the first sealing structure 41 from achieving a sealing connection; in addition, setting the boss structure 7 and the recessed part 8 on the front door side panel 31 helps to improve the local rigidity of the front door side panel 31, simplify the number of parts of the front door body 3, and thus simplify the production and assembly process of the front door body 3.

[0048] In a possible implementation, the rear door side panel 21 and the corresponding position of the boss structure 7 are provided with a snap-fit ​​groove. The first sealing structure 41 includes a snap-fit ​​part. The first sealing structure 41 and the rear door side panel 21 are detachably connected through the snap-fit ​​groove and the snap-fit ​​part. The snap-fit ​​part can be used to position the installation position of the first sealing structure 41, which facilitates the quick positioning of the first sealing structure 41, reduces the assembly tolerance between the first sealing structure 41 and the boss structure 7, and helps to improve the sealing performance after the first sealing structure 41 and the boss structure 7 are fitted together.

[0049] In a possible implementation, a limiting structure is provided at the connection position between the front door inner panel 33 and the front door side panel 31. The limiting structure can restrict the connection position between the rear door body 2 and the front door body 3. Understandably, after the rear door panel rotates to the point where it abuts against the limiting structure, the rear door panel is connected to the front door panel. The limiting structure can provide support for the rear door body 2 and restrict the rotation position of the rear door body 2. At the same time, the limiting structure can prevent the rear door body 2 from colliding with the door frame 1.

[0050] Specifically, the second seal can be set on the limiting structure. During the cooperation between the rear door body 2 and the front door body 3, the rear door body 2 abuts against the second sealing structure 42 set on the limiting structure. While the limiting structure restricts the rotation of the rear door body 2, the rear door body 2 and the second sealing structure 42 form a sealed connection. Thus, setting the second sealing structure 42 on the limiting structure can provide a buffer for the abutment process between the rear door body 2 and the limiting structure.

[0051] Specifically, during the connection process between the rear door body 2 and the front door body 3, after the rear door body 2 rotates to the connection position defined by the limiting structure, the second seal is sealed to the rear door body 2, the first seal is sealed to the boss structure 7, and a sealing isolation cavity 5 is formed between the first seal and the second seal.

[0052] In possible implementations, refer to Figure 2 The rear door body 2 also includes a rear door inner panel 24, which is connected to the rear door inner panel 23. Specifically, the rear door inner panel 24 and the rear door inner panel 23 are detachably connected, and a snap-fit ​​structure is provided between them. After the rear door inner panel 24 and the rear door inner panel 23 are connected, they form the interior surface of the rear door body 2, which helps to improve the cleanliness and aesthetics of the car interior. Specifically, the rear door inner panel 24 and the rear inner panel form a rear door inner cavity, in which various mechanical components in the rear door body 2 can be accommodated, and the rear door inner cavity can effectively shield external noise from the vehicle.

[0053] Specifically, after the rear door inner panel 24 is connected to the rear inner panel, a platform structure is formed on the rear door inner panel 23. The platform structure can cooperate with the limiting structure to limit the connection position between the rear door body 2 and the front door body 3, preventing the rear door inner panel 24 from colliding with the limiting structure during the process of the rear door body 2 rotating to cooperate with the front door body 3. Preferably, the second sealing structure 42 is connected to the limiting structure, and after the rear door body 2 rotates to cooperate with the front door body 3, the second sealing structure 42 can form a sealed connection with the platform structure.

[0054] In a possible implementation, the front door body 3 includes a front door inner panel 34, which is connected to the rear door inner panel 23. Specifically, the front door inner panel 34 and the front door inner panel 33 are detachably connected, and a snap-fit ​​structure is provided between them. Before being connected, the front door inner panel 34 forms the interior surface of the front door body 3, which helps to improve the cleanliness and aesthetics of the car interior. Specifically, the front door inner panel 34 and the front inner panel form a front door cavity, in which various mechanical components of the front door body 3 can be housed. Furthermore, the front door cavity and the rear door cavity can work together to shield external noise and heat, thus improving the comfort of the vehicle interior.

[0055] Specifically, one end of the front door inner panel 34 is connected to the front door side panel 31. The front door inner panel 34 can cover the front door side panel 31 and the front door inner panel 33 after they are connected to form the first welding surface, which ensures the aesthetics of the interior of the front door body 3, and at the same time protects the first welding surface and prevents the first welding surface from rusting, which is conducive to improving the structural strength of the front door body 3.

[0056] In a possible implementation, the second sealing structure 42 is disposed at the connection position between the front door inner panel 34 and the front door side panel 31. The second sealing structure 42 can abut against the rear door inner panel 24. In this way, collisions between the front door inner panel 34 and the rear door inner panel 24 can be avoided during the opening and closing of the door. At the same time, it helps to improve the sealing effect between the front door body 3 and the rear door body 2.

[0057] In possible implementations, refer to Figure 3 The second sealing structure 42 includes a door sealing structure 421 and a door frame sealing structure 422. The door sealing structure 421 is sealed to the rear door side panel 21, and the door frame sealing structure 422 can abut against the rear door inner panel 24 and be sealed to the door frame 1. In this way, after the front door 3 and the rear door 2 are fitted together, the seal between the front door 3 and the rear door 2 can be achieved, and the gap between the front door 3 and the door frame 1 can be sealed. This simplifies the sealing structure and thus simplifies the assembly process of the door structure.

[0058] Specifically, the second sealing structure 42 engages with the limiting structure, the door sealing structure 421 faces the platform structure, and the door frame sealing structure 422 faces the rear door inner panel 24; when the front door 3 is rotated to engage with the door frame 1, the door frame sealing structure 422 is sealed to the door frame 1; when the rear door 2 is rotated to engage with the front door 3, the door sealing structure 421 is sealed to the platform structure, and the door frame sealing structure 422 abuts against the rear door inner panel 24.

[0059] In a possible implementation, the first sealing structure 41 and the door sealing structure 421 are sealing strip structures with air chambers. When the front and rear doors are rotated to engage with the door frame 1, the air chambers can be compressed and deformed. Utilizing the pressure of the air inside the air chambers, the sealing strips can tightly fill the irregular gaps between the front door 3, the rear door 2, and the door frame 1, effectively blocking external rainwater and dust contaminants, while also effectively isolating external noise and improving thermal insulation performance. Furthermore, during the closing process of the doors, the sealing strips with air chambers can effectively buffer the impact between the door bodies, reducing collisions with various door components during the closing process, which is beneficial to the service life of the vehicle door structure.

[0060] Specifically, the first sealing structure 41 contacts the boss structure 7 and undergoes compression deformation. When the door structure is fully closed, the first sealing structure 41 reaches a first preset compression amount, which can be 4-6 mm. The door sealing structure 421 contacts the platform structure and undergoes compression deformation. When the door structure is fully closed, the door sealing structure 421 reaches a second preset compression amount, which can be 2.5-3.5 mm. By controlling the first and second preset compression amounts within the above ranges, good sealing between the front door body 3 and the rear door body 2 can be ensured. Understandably, the first and second preset compression amounts can be adjusted according to the actual distance between the front door body 3 and the rear door body 2 after they are fitted together.

[0061] Using the door structure provided in this application embodiment, after the front door 3 rotates to engage with the door frame 1, the door frame sealing structure 422 is sealed to the door frame 1; during the process of the rear door 2 rotating to engage with the front door 3 and the door frame 1, the door sealing structure 421 contacts the platform structure and undergoes compression deformation, and the first sealing structure 41 contacts the boss structure 7 and undergoes compression deformation; when the rear door 2 rotates to the connection position defined by the limiting structure, the door sealing structure 421 is sealed to the platform structure, the first sealing structure 41 is sealed to the boss structure 7, and a spaced sealing isolation cavity 5 and a cavity 6 are formed between the front door 3 and the rear door 2, and the front door outer panel 32 and the rear door outer panel 22 are flush to form the appearance surface of the door structure.

[0062] Secondly, this application proposes a vehicle including the door structure described in any of the embodiments, so that the vehicle can achieve a pillarless effect, improving the space utilization of the vehicle; and the door structure has good sealing performance, which can effectively improve the comfort and cleanliness of the vehicle interior.

[0063] The above description is merely an embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this application should be included within the scope of the claims of this application.

[0064] Although embodiments of this application have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of this application, and such modifications and variations all fall within the scope defined by the appended claims.
