As shown in fig. 1 to 4, the back door according to the embodiment of the present application includes a back door inner panel 1, a back door outer panel 2, and a reinforcement panel 3. The backdoor inner plate 1 is provided with a first hinge mounting hole, the backdoor outer plate 2 is connected with the backdoor inner plate 1, and a hinge mounting cavity towards two ends with the first hinge mounting hole is formed between the backdoor outer plate 2 and the backdoor inner plate 1. The reinforcing plate 3 comprises a first connecting part 31, a supporting part 33 and a second connecting part 32 which are connected in sequence, the edge of the back door outer plate 2 is provided with a covered edge 21, and the edge of the back door inner plate 1 and the first connecting part 31 are inserted into a covered edge cavity formed by the covered edge 21. The support portion 33 is located in the hinge mounting cavity and provided with a second hinge mounting hole 34 corresponding to the first hinge mounting hole, and the second connecting portion 32 is welded to at least one of the back door inner panel 1 and the back door outer panel 2.

According to the back door of the embodiment of the application, the hinge 4 is simultaneously connected with the back door inner plate 1 and the reinforcing plate 3 through the first hinge mounting hole and the second hinge mounting hole 34, so that the installation of the hinge 4 on the back door is realized, and the strength and the rigidity of the hinge mounting point of the back door are ensured. Wherein, the first connecting portion 31 of reinforcing plate 3 presss from both sides and establishes between backdoor inner panel 1 and backdoor planking 2 and spacing in the chamber of borduring that 21 formation of borduring of backdoor planking 2, and second connecting portion 32 then welds with backdoor inner panel 1 and/or backdoor planking 2, accomplishes the stable installation of reinforcing plate 3 from this, only needs to set up second connecting portion 32 solder joint this moment, and the installation degree of difficulty of reinforcing plate 3 is lower.

As shown in fig. 3, the edge 21 of the outer back door panel 2 is overlapped with the surface of the inner back door panel 1 away from the outer back door panel 2, the first connecting portion 31 has a plate-like structure, and the first connecting portion 31 is interposed between the outer back door panel 2 and the inner back door panel 1 and at least partially located in the edge-covered cavity. As shown in fig. 1, 2 and 4, the first hinge mounting holes and the second hinge mounting holes 34 are two and one-to-one corresponding to each other, and the hinges 4 are connected to the back door inner panel 1 and the reinforcement panel 3 by two bolts.

In some embodiments of the present application, as shown in fig. 3, the second connecting portion 32 is interposed between the back door inner panel 1 and the back door outer panel 2 and has a first welding surface and a second welding surface opposite to each other in the thickness direction, the first welding surface being welded to the back door inner panel 1, and the second welding surface being welded to the back door outer panel 2.

That is, the second connecting portion 32 is welded to the back door inner panel 1 and the back door outer panel 2 at the same time, so that the mounting strength of the reinforcing panel 3 on the back door is higher, and the strength and rigidity of the hinge mounting point can be increased better.

Specifically, the second connecting portion 32 has a plate-shaped structure, and the first welding surface of the second connecting portion 32 is in contact with the back door inner panel 1, and the second welding surface is in contact with the back door outer panel 2.

In some embodiments of the present application, as shown in fig. 3, the supporting portion 33 includes a first supporting plate 331 and a second supporting plate 332 which are angled, the first supporting plate 331 is connected to the first connecting portion 31, the second supporting plate 332 is connected to the second connecting portion 32, at least a portion of the first supporting plate 331 is in close contact with the back door inner panel 1, and the second hinge mounting hole 34 is provided on the first supporting plate 331.

From this, first backup pad 331 is equivalent to and thickens the setting to backdoor inner panel 1, and hinge 4 passes through the bolt simultaneously with first backup pad 331 and backdoor inner panel 1 continuous back, and first backup pad 331 can not remove the deformation for backdoor inner panel 1 relatively, and hinge 4's installation intensity is higher.

Meanwhile, the second support plate 332, which is angled with respect to the first support plate 331, is also angled with respect to the back door inner panel 1, thereby having better structural strength and rigidity.

In some embodiments of the present application, as shown in fig. 3, a reinforcement cavity 11 having a triangular cross section is formed between the second support plate 332 and the back door inner panel 1.

From this, under the limited circumstances in hinge installation cavity's space, the reinforcement chamber 11 that forms between second backup pad 332 and the back of the body door inner panel 1 can effectively improve the structural strength and the rigidity of back of the body door in hinge installation department, need not carry out thickening processing to first backup pad 331 again from this, effectively reduces the weight of reinforcing plate 3 from this, satisfies the lightweight demand of vehicle.

Specifically, as shown in fig. 3, the second support plate 332 is located below the first support plate 331, and the included angle between the first support plate 331 and the second support plate 332 is an obtuse angle.

In some embodiments of the present invention, the first support plate 331 is provided with first reinforcing ribs 37, and the second support plate 332 is provided with second reinforcing ribs 38.

First strengthening rib 37 effectively improves the anti intensity of buckling of first backup pad 331, and second strengthening rib 38 effectively improves the anti intensity of buckling of second backup pad 332, from this at frequent switching back door in-process, first backup pad 331 and second backup pad 332 can realize the support to hinge mounting point more steadily, and back door structural strength and rigidity in hinge mounting point department are higher, more non-deformable.

Specifically, the reinforcing plate 3 is integrally formed by punching, the first reinforcing ribs 37 extend along the height direction of the first support plate 331, the second reinforcing ribs 38 extend along the height direction of the second support plate 332, the first reinforcing ribs 37 protrude out of the upper surface of the first support plate 331, the lower surface of the first support plate 331 correspondingly forms first reinforcing grooves, the second reinforcing ribs 38 protrude out of the upper surface of the second support plate 332, and the lower surface of the second support plate 332 correspondingly forms second reinforcing grooves.

In some embodiments of the present application, the support portion 33 further includes at least two side plates 333 connecting the first support plate 331 and the second support plate 332, and the side plates 333 are spaced apart in a width direction of the back door inner panel 1.

Therefore, the arrangement of the side plates 333 effectively improves the bending strength of the joint of the first support plate 331 and the second support plate 332, the whole structural strength and rigidity of the reinforcing plate 3 are higher, and the support stability of the hinge mounting point is stronger.

Specifically, the side plates 333 have two and substantially triangular plates, wherein one side plate 333 is connected to first edges of the first and

second support plates

331 and 332 in the width direction, and the other side plate 333 is connected to second edges of the first and

second support plates

331 and 332 in the width direction.
