Referring to fig. 1, the back door structure includes a back door inner panel 1, a back door outer panel 2, and a wire harness 3. Wherein, be formed with the cavity between back door inner panel 1 and the back door outer panel 2, can strengthen the intensity of back door structure. The back door inner plate 1 and the back door outer plate 2 are oppositely connected to form a quadrilateral structure, and the quadrilateral structure comprises a top cross beam 4, two side beams 5 and a bottom cross beam. The middle of the quadrangular structure is used for installing glass, and a rear view area of the automobile is formed. The back door structure is provided with a wire harness inlet and a wire harness outlet, and the wire harness 3 is used for providing power for electric equipment in the back door structure after passing through the back door inner plate 1 and the back door outer plate 2.

Referring to fig. 2, the back door inner panel 1 at the upper end of the side member 5 is provided with a first through hole 6, and a welded edge overlap region of the back door inner panel 1 and the back door outer panel 2 at a connection position of the side member 5 and the roof cross member 4 is provided with a second through hole 7. That is, the first through hole 6 is provided at the left or right upper end of the back door inner panel 1, and the second through hole 7 is provided at the upper left or right corner formed by the connection of the side sill 5 and the roof cross member 4.

Referring again to fig. 2, the wire harness 3 passes through the first through hole 6 between the back door inner panel 1 and the back door outer panel 2, and then passes out of the second through hole 7. In the present embodiment, the first through hole 6 and the second through hole 7 are located on the same side of the back door structure. That is, when the first through hole 6 is located at the left upper end of the back door inner panel 1, the second through hole 7 is provided at the left upper corner formed by the connection of the side sill 5 and the roof cross member 4; when the first through hole 6 is located at the upper right end of the back door inner panel 1, the second through hole 7 is provided at the upper right corner formed by the connection of the side sill 5 and the roof cross member 4. The arrangement makes the outlet occupation space of the wire harness smaller, makes the wiring route of the wire harness 3 in the back door inner plate 1 and the back door outer plate 2 shorter, and facilitates penetration and penetration, so that the Z-directional section size of the back door structure can be reduced, the rear view field area is increased, and the weight of the back door structure is reduced.

In the following embodiment, a detailed example is given in which the first through hole 6 is located at the left upper end of the back door inner panel 1, and the second through hole 7 is provided at the upper left corner formed by the connection of the side sill 5 and the roof cross member 4.

As shown in fig. 4, the second through-hole 7 is provided at the joint position of the side sill 5 and the roof cross member 4 in the region where the welding edge overlap is required for the back door inner panel 1 and the back door outer panel 2, i.e., in the upper left corner position. When the second through hole 7 is provided at this position, the welding edge overlap region of the back door inner panel 1 and the back door outer panel 2 at this position need only be left without welding. The size of the second through hole 7 can be determined according to the size and the requirement of the wire harness 3, that is, the non-welding range is the size of the second through hole 7, and is determined according to the size of the wire harness.

Referring to fig. 3, the back door inner panel 1 at the upper end of the side sill 5 is provided with a flat area 11. The first through hole 6 is provided at this planar area 11. The planar area 11 allows the sheet metal to have a sufficient planar surface for providing a sealing surface for the harness sheath outside the harness 3 when penetrating into the first through hole 6 for waterproofing and dust prevention. In this embodiment, the planar area 11 is adjacent to the upper left corner hinge of the back door structure.

Referring again to fig. 4, a second through hole 7 is provided in the back door inner panel 1 at the connection position (i.e., the upper left corner) of the side sill 5 and the roof cross member 4. That is, at the welding edge position of the back door inner panel 1 and the back door outer panel 2, the second through hole 7 is formed for the wire harness 3 to pass out by providing the edge position of the back door inner panel 1 with a groove.

Referring to fig. 5 to 7, a first opening 8 (i.e., a groove) is formed on a side of the back door outer panel 2 facing away from the back door inner panel 1 at a connection position (i.e., an upper left corner angle) of the side sill 5 and the roof cross member 4, and a second opening 9 (i.e., a groove) is formed on a side of the back door inner panel 1 facing away from the back door outer panel 2 at a welding edge. The first opening 8 and the second opening 9 are opposite to each other, and the two openings surround the second through hole 7, so that the wire harness 3 can be threaded out. Except for the opening position, other welding edges of the back door inner plate 1 and the back door outer plate 2 outside the second through hole 7 are overlapped and welded to form a back door structure.

Referring to fig. 8, the back door structure further includes a reinforcing plate 10. The reinforcement plate 10 is welded to the back door inner panel 1 at the corner position. That is, the reinforcing plate 10 is welded to the back door inner panel 1 at a position near the second opening 9, wherein one side of the reinforcing plate 10 is welded flush with the edge of the second opening 9. The reinforcement plate 10 serves to increase structural strength at the outlet of the wire harness 3 and to provide rigidity to the back door inner panel 1.

The embodiment of the application also provides a vehicle provided with the back door structure of the embodiment. In the vehicle, the wire harness 3 directly passes through the left upper corner of the back door structure after entering from the first through hole 6 on the back door inner plate 1, namely, the outlet is arranged in the area where the welding edges are needed to be overlapped at the left upper corners of the back door outer plate 2 and the back door inner plate 1.

The back door structure that this embodiment provided includes back door inner panel, back door planking and pencil, and back door inner panel and back door planking set up relatively and connect and form quadrilateral structure, and quadrilateral structure includes top crossbeam, two curb girders and bottom crossbeam, and the back door inner panel of curb girder upper end is provided with first through-hole, the curb girder with the welding limit overlap joint region of back door inner panel and back door planking of the hookup location of top crossbeam is provided with the second through-hole, and the pencil penetrates between back door inner panel and the back door planking from first through-hole and follow wear out in the second through-hole. The position of the second through hole is not increased in the cross section size of the top cross beam, and the area of the rear view field is not reduced, so that the weight of the whole vehicle is not influenced.
