[0041] In the technical solution of the present disclosure, words such as “connect”, “couple” or “connected” are not limited to physical or mechanical connections, but may include electrical connections.

[0042] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0043] It should be noted that, in the present invention, directions such as inside, outside, up, down, front and back can be defined according to the driver's perspective in a scenario where the driver is driving the vehicle forward.

[0044] The utility model embodiment provides a vehicle door, see Figures 1 to 3 As shown, it includes a door inner panel 1, a door outer panel 2 and a door reinforcement assembly. The front and rear sides of the plate body of the door inner panel 1 are correspondingly provided with a front flange 11 and a rear flange 12. The edges of the front flange 11 and the rear flange 12 are bent and extended toward the outer side of the door outer panel 2.

[0045] Door reinforcement kit includes:

[0046] The waistline reinforcement plate 3 is extended in the front-rear direction and fixedly connected to the upper side end of the door inner panel 1;

[0047] The hinge reinforcement plate 4 is extended in the up-down direction and fixedly connected to the front flange 11, and the upper end of the hinge reinforcement plate 4 is fixedly connected to the front end of the waistline reinforcement plate 3;

[0048] The outer panel support plate 5 is arranged to extend obliquely along the front-to-back direction and from top to bottom. The front end of the outer panel support plate 5 is fixedly connected to the hinge reinforcement plate 4 , and the rear end of the outer panel support plate 5 is fixedly connected to the rear flange 12 .

[0050] In the embodiment of the utility model, the front end portion of the outer panel support plate 5 is fixedly connected to the hinge reinforcement plate 4, forming a stable connection between the front end portion of the outer panel support plate 5, the hinge reinforcement plate 4 and the door inner panel 1; on this basis, the rear end portion of the outer panel support plate 5 is fixedly connected to the rear flange 12, forming a stable overlapping structure between the outer panel support plate 5, the hinge reinforcement plate 4, the waistline reinforcement plate 3 and the door inner panel 1, ensuring that the outer panel support plate 5 has high structural strength, providing a strength margin for structural optimization of the outer panel support plate 5 (for example: weight reduction, reducing material specifications), which is beneficial to reducing the weight of the door structure and reducing the driving energy consumption of the vehicle provided with the door.

[0051] In some optional embodiments, the fixed connection method is welding. The outer panel support plate 5, as a door structural component, plays an important role in resisting the deformation of the outer panel at the door. In the early stage of the door deformation due to stress, the outer panel support plate 5, due to the welded overlap structure connecting the front flange 11 and the rear flange 12, horizontally penetrates and transmits the force to the hinge reinforcement plate 4, the waistline reinforcement plate 3 and the structure of the door inner panel 1. Welding points are preferentially arranged in areas with large overlaps with the door inner panel 1, and are optimized in combination with the outer panel dent resistance analysis results analyzed by computer. To avoid stress concentration at some welds causing weld tearing and other phenomena, a 3mm gap should be maintained in non-welded areas to avoid assembly interference.

[0052] In some optional embodiments, the outer panel support plate 5 is made of galvanized plate and is sprayed with an anti-rust coating on the surface. After the overall welding of the door is completed, the vehicle body is brought into the painting room for electrophoresis and painting, which can meet the anti-corrosion requirements of the vehicle and the door.

[0053] In the embodiment of the utility model, the outer panel support plate 5 is in contact with the vehicle door outer panel 2, and can provide support force in the inner and outer directions to the vehicle door outer panel 2, thereby improving the rigidity of the vehicle door outer panel 2. In addition, the outer panel support plate 5 is arranged to extend obliquely from top to bottom along the front-to-back direction, thereby increasing the contact area with the vehicle door outer panel 2, which is conducive to improving the support force for the vehicle door outer panel 2, thereby improving the rigidity of the vehicle door outer panel 2.

[0054] In the embodiment of the utility model, the waistline reinforcement plate 3 is extended in the front-to-back direction and fixedly connected to the upper side end of the door inner panel 1; the hinge reinforcement plate 4 is extended in the up-down direction and fixedly connected to the front flange 11, and the upper end of the hinge reinforcement plate 4 is fixedly connected to the front end of the waistline reinforcement plate 3; the outer panel support plate 5 is extended in the front-to-back direction and tilted from top to bottom, the front end of the outer panel support plate 5 is fixedly connected to the hinge reinforcement plate 4, and the rear end of the outer panel support plate 5 is fixedly connected to the rear flange 12, forming a stable overlap structure between the outer panel support plate 5, the hinge reinforcement plate 4, the waistline reinforcement plate 3 and the door inner panel 1, which can effectively improve the door rigidity.

[0057] The first extension area 41 is attached to and fixedly connected with the plate body of the door inner panel 1;

[0058] One bending area is arranged between the first extension area 41 and the second extension area 42, and the bending direction when bending is toward the outer side close to the door outer panel 2; the other bending area is arranged between the second extension area 42 and the third extension area 43, and the bending direction when bending is toward the front side;

[0059] The second extension area 42 and the third extension area 43 are fixedly connected to the front flange 11 respectively.

[0061] In some embodiments of the present invention, optionally, see Figure 1 and Figure 2As shown, the front flange 11 includes a first edge portion 111 and a second edge portion 112;

[0062] The contour shape of the first side portion 111 is the same as the contour shape of the second extension area 42, and the two are arranged in close contact; the second extension area 42 is fixedly connected to the first side portion 111;

[0063] The contour shape of the second side portion 112 is the same as the contour shape of the third extension area 43 , and the two are arranged in close contact with each other; the third extension area 43 is fixedly connected to the second side portion 112 .

[0064] Through the above arrangement, the connection strength between the hinge reinforcement plate 4 and the door inner panel 1 is further improved, which is beneficial to improving the rigidity of the hinge connection between the door and the vehicle body.
