[0035] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0036] In vehicle door structure design, the door inner panel 2 is typically joined to the inner and outer panels through flanging, bonding, seam welding, and other methods. The door inner panel 2 has a stamped depth in the thickness direction of the door structure, meaning it has side surfaces. The joined inner and outer panels form a door panel cavity 3, within which numerous components are located. For a vehicle door structure, the opening and closing side is the side that opens and closes, while the hinged side is the side that connects to the vehicle body through a hinge.

[0037] Among them, the door lock reinforcement plate 4 is usually installed at the lock part of the door inner panel 2, which can improve the rigidity of the installation part, ensure the firmness of the installation of the door accessories, and also improve the rigidity and connection strength of the door; the outer panel support plate 5 is usually installed in the door panel cavity 3, and is firmly connected between the door inner panel 2 and the inner and outer panels to provide additional support and reinforcement, thereby supporting and reinforcing the door outer panel 1, helping the door outer panel 1 to resist the impact of external forces, and effectively reducing the occurrence of dents and deformation.

[0038] like Figure 1-Figure 2 As shown, an embodiment of the present application provides a vehicle door structure, including a door outer panel 1, a door inner panel 2, a door lock reinforcement plate 4 and an outer panel support plate 5; the door inner panel 2 is connected to the door outer panel 1 and forms a door panel cavity 3 between the door inner panel 2 and the door outer panel 1; the door lock reinforcement plate 4 is arranged in the door panel cavity 3 and is located on the opening and closing side of the vehicle door structure, and the door lock reinforcement plate 4 is connected to the door inner panel 2; the outer panel support plate 5 is arranged in the door panel cavity 3, and the two ends of the outer panel support plate 5 are respectively fixed on the hinge side and the opening and closing side of the door panel cavity 3, presenting a horizontal state in the door panel cavity 3, and the outer panel support plate 5 is overlapped and fixed on the door lock reinforcement plate 4, and specifically can be firmly connected by welding.

[0039] With such arrangement, the outer panel support plate 5 needs to have a certain span distribution in the door panel cavity 3 and be fixedly connected to other structures for the design purpose of support and reinforcement. Since the door lock reinforcement plate 4 is located on the opening and closing side of the vehicle door structure, the outer panel support plate 5 is fixed on the opening and closing side by overlap welding with the door lock reinforcement plate 4. That is, on the opening and closing side of the vehicle door structure, the outer panel support plate 5 does not need to be welded and fixed to the door inner panel 2, and no additional appearance welding points will be generated on the opening and closing side of the vehicle door structure, which solves the problem of how to reduce the appearance welding points of the vehicle door and improve the aesthetics of the vehicle door appearance in the prior art.

[0040] Furthermore, compared to the prior art method of welding the outer panel support plate 5 to the door inner panel 2 on the opening and closing side, and using rubber strips and decorative panels to cover the exterior weld points of the door, the solution provided by this application re-arranges the internal components of the door structure, fundamentally reducing the formation of exterior weld points, improving the quality of the door's appearance, and reducing the costs associated with existing traditional methods. This solution is highly feasible and helps provide greater design space for the exterior design of the door structure. In addition, because the outer panel support plate 5 is fixed to the door lock reinforcement plate 4, which serves as a structural reinforcement, after testing and verification, compared to the prior art method of welding the outer panel support plate 5 to the door inner panel 2 on the opening and closing side, the solution provided by this application also optimizes the impact resistance of the outer panel support plate 5 and improves the dent resistance of the door outer panel 1.

[0041] In the longitudinal direction of the vehicle door structure, the size of the door lock reinforcement plate 4 is larger than the size of the outer panel support plate 5 to ensure the firmness of the welding of the outer panel support plate 5 on the opening and closing side, and at the same time ensure the basic function of the door lock reinforcement plate 4.

[0042] In some specific embodiments, the door lock reinforcement plate 4 includes a first plate portion 401 and a second plate portion 402 folded relative to the first plate portion 401. The door lock reinforcement plate 4 is roughly an L-shaped plate. The second plate portion 402 is closer to the door outer panel 1 than the first plate portion 401. The first plate portion 401 is overlapped and fixed to the side of the door inner panel 2, and the outer panel support plate 5 is overlapped and fixed to the second plate portion 402.

[0043] With such arrangement, on the one hand, the door lock reinforcement plate 4 is designed as a three-dimensional structure with better structural strength; on the other hand, while ensuring the connection between the door lock reinforcement plate 4 and the door inner panel 2, a overlapping position is provided for the outer panel support plate 5 to facilitate the assembly process.

[0044] Furthermore, in some preferred embodiments, the side surface of the door inner panel 2 located on the opening and closing side has a first area 201 and a second area 202, and the second area 202 protrudes into the door panel cavity 3 relative to the first area 201, and the formation of the first area 201 and the second area 202 can be achieved through a stamping process; the first plate portion 401 is partially fitted with the surface of the second area 202, and there is a gap between the first plate portion 401 and the first area 201; the second plate portion 402 is opposite to the first area 201 and has a gap.

[0045] With such arrangement, in the door panel cavity 3, the first area 201 forms an avoidance space relative to the second area 202. On the one hand, this is conducive to the first plate portion 401 of the door lock reinforcement plate 4 and the door inner panel 2 being fully fitted and welded, thereby enhancing the welding stability. On the other hand, the interval between the second plate portion 402 and the first area 201 also has the function of providing a buffer space. When the outer panel support plate 5 is subjected to force due to impact, deformation and displacement space is provided for the door lock reinforcement plate 4, which is conducive to making the deformation of the car door as much as possible inside the car door structure, while the deformation degree of the outer contour of the car door structure is low, so that the car door is easy to open when a collision accident occurs.

[0046] In some other specific embodiments, the vehicle door structure also includes a hinge reinforcement plate 6, which is arranged in the door panel cavity 3 and connected to the door inner panel 2. The hinge reinforcement plate 6 is located on the hinge side of the vehicle door structure. The design of the hinge reinforcement plate 6 helps to improve the stress conditions in the door hinge installation area, reduce stress concentration, and thus reduce the risk of sheet metal cracking.

[0047] Based on this, the first end of the outer panel support plate 5 can be overlapped and fixed to the door lock reinforcement plate 4, and a stable connection can be achieved by welding. The second end of the outer panel support plate 5 can be overlapped and fixed to the door inner panel 2 or the hinge reinforcement plate 6, and a stable connection can be achieved by welding. Preferably, the second end of the outer panel support plate 5 is overlapped and fixed to the hinge reinforcement plate 6. In this way, the outer panel support plate 5 spans the entire door panel cavity 3, and its two ends are respectively connected to the structural reinforcement members in the door panel cavity 3, thereby improving the impact resistance of the vehicle door structure.

[0048] In other specific embodiments, in the inward and outward directions of the vehicle door structure, the outer panel support plate 5 is connected to the side of the door lock reinforcement plate 4 facing the door outer panel 1. In this way, since the door lock reinforcement plate 4 and the hinge reinforcement plate 6 are fixed to the side of the door inner panel 2 facing the door outer panel 1, after the door lock reinforcement plate 4 and the hinge reinforcement plate 6 are welded and fixed, the position of the outer panel support plate 5 is determined based on the position of the door lock reinforcement plate 4 and the hinge reinforcement plate 6, and then welded and fixed. The outer panel support plate 5 is fixed to the side of the door lock reinforcement plate 4 and the hinge reinforcement plate 6 facing the door outer panel 1, which facilitates the orderly and reasonable assembly process of the vehicle door.

[0049] In other preferred embodiments, the portion of the outer panel support plate 5 connected to the door lock reinforcement plate 4 is provided with a partially protruding boss 501. That is, the first end of the outer panel support plate 5 is provided with a partially protruding boss 501. The boss 501 protrudes toward the door lock reinforcement plate 4 and is in contact with the surface of the door lock reinforcement plate 4. The boss 501 can be formed by stamping the outer panel support plate 5.

[0050] With such arrangement, the boss 501 of the outer panel support plate 5 can fully contact the door lock reinforcement plate 4, so that the connection stability after welding is higher and the strength of the vehicle door structure is higher.

[0051] In some optional embodiments, the outer panel support plate 5 is provided with a weight-reducing hole 502, which is a strip-shaped hole extending along the length direction of the outer panel support plate 5. This design is conducive to the door structure meeting the lightweight design requirements.

[0052] In some other optional embodiments, the edge of the outer panel support plate 5 is provided with a weight-reducing notch 503, which is a strip-shaped notch extending along the length of the outer panel support plate 5. This design is conducive to the door structure meeting the lightweight design requirements.

[0053] In some other preferred embodiments, the vehicle door structure further includes an anti-collision beam 7, which is provided in the door panel cavity 3 and below the outer panel support plate 5; wherein,

[0054] The angle between the central axis of the outer panel support plate 5 and the central axis of the anti-collision beam 7 is less than or equal to 20°, and can be set to 10° for example;

[0055] The included angle between the central axis of the outer plate support plate 5 and the horizontal line is less than or equal to 8°, and illustratively, can be set to 4°.

[0056] With such arrangement, after testing and verification, it has been found that when the outer panel support plate 5 and the anti-collision beam 7 have the above-mentioned positional relationship, the vehicle door structure has better anti-collision performance.

[0057] It should be noted that the connection between the anti-collision beam 7 and the door inner panel 2 can continue to use the existing connection method.

[0058] Based on the above-mentioned door structure, the embodiment of the present application further provides a vehicle body, which includes the above-mentioned door structure. Since the vehicle body has the above-mentioned door structure, the beneficial effects of the vehicle body brought by the door structure can be found in the above content and will not be repeated here.
