Fig. 2 shows a schematic structure of a vehicle door 2. Fig. 3 shows a schematic structure of the vehicle door 2 with the outer panel 21 removed. As shown in fig. 2 to 3, the door 2 includes an inner panel 20, an outer panel 21, and a reinforcing structure 22. It is to be understood that in the description of the present invention, the "inside-outside" and "inside-outside direction" are with respect to the cabin of the vehicle, i.e., the side adjacent to the cabin is the inside and the side remote from the cabin is the outside. Wherein the "medial-lateral direction I" is indicated by the arrows in fig. 2 and 3, for example.
The outer plate 21 is fixed to the outer side 201 of the inner plate 20, that is, the outer plate 21 is fixed to a side of the inner plate 20 away from the cabin. The periphery of the outer panel 21 has an inward flange to wrap around the periphery of the inner panel 20. In other words, the peripheries of the outer panel 21 and the inner panel 20 may be fixed by the burring so that the peripheries of the outer panel 21 and the inner panel 20 are joined together. Preferably, the periphery of the outer plate 21 is welded to the periphery of the inner plate 20. And an accommodating chamber is arranged between the outer side surface 201 of the inner plate 20 and the inner side surface of the outer plate 21. In the present embodiment, the inner plate 20 and the outer plate 21 are each sheet metal plates.
As shown in fig. 5 to 11, the reinforcing structure 22 includes a reinforcing main body portion 220 and an adhesive portion 221. The reinforcement main body portion 220 is fixed to the inner region of the side member 202 of the inner panel 20 and is located in the receiving chamber.

The reinforcing body portion 220 made of a nonmetallic material is arranged on the inner plate 20, so that the overall weight of the vehicle door 2 is reduced, the oil consumption is reduced, the energy saving and emission reduction effects are achieved, and the process molding of the reinforcing body portion 220 is less than that of a molding die required by a sheet metal reinforcing plate, so that the die cost is reduced, and the production cost of the vehicle door 2 is further reduced.
The reinforcing body portion 220 has oppositely disposed first and second sides 2202, 2203, the first and second sides 2202, 2203 each extending along the length of the reinforcing body portion 220 and each abutting an inner side 2200 and an outer side 2201 of the reinforcing body portion 220. The first side 2202 is located outside the second side 2203 in the width direction W of the door 2, i.e., the first side 2202 is closer to the edge of the inner panel 20 than the second side 2203.
The outer side surface of the bonding portion 221 is bonded to and covers the inner side surface 2200 of the reinforcement main body portion 220, and the inner side surface of the bonding portion 221 is bonded to and covers the outer side surface 201 of the inner panel 20. The bonding portion 221 is disposed between the reinforcing body portion 220 and the inner plate 20, so that the fixing area of the reinforcing body portion 220 and the inner plate 20 is larger, the firmness of the reinforcing body portion 220 fixed to the inner plate 20 is improved, the structural strength of the matching position of the reinforcing body portion 220 and the inner plate 20 and the outer plate 21 is improved, and the gap and the surface difference between the outer plate 21 located on the outer side of the reinforcing body portion 220 and the adjacent sheet metal car body and the tail lamp are further ensured.
As shown in fig. 5, the reinforcement main body 220 adopts a hollowed-out skeleton, so that the weight of the reinforcement main body 220 can be reduced while the structural strength of the reinforcement main body is ensured, and the overall weight of the vehicle door 2 is further reduced. The material of the reinforcing body portion 220 is preferably plastic, and the process is simpler and the weight is lower, so that the overall weight of the door 2 is lower and the production cost is lower.
In this embodiment, the vehicle door 2 includes two reinforcing structures 22, the two reinforcing structures 22 are disposed opposite to each other and are disposed in the inner areas of the two opposite side members 202 of the inner panel 20, and the two reinforcing structures 22 are disposed on the two sides 2030 of the window 203 of the inner panel 20. Preferably, the two reinforcing structures 22 are symmetrically disposed. Of course, in the present invention, the number of the reinforcing structures 22 is not limited to two, and the scope of the present invention is not limited thereto.
In the description of the embodiment of the present invention, the "up-down direction H" is shown by an arrow in fig. 2 and 3, for example. It should be noted that this direction indication is for illustrative purposes only and is not intended to limit the scope of the present invention.
