Referring to fig. 1 to 6, a side-opening back door reinforcement structure provided by the present utility model will now be described. The side-opening back door reinforcing structure comprises: the back door inner plate 1, the back door hinge reinforcing plate 3 and the back door outer plate supporting plate 5 are sequentially stacked from inside to outside of the automobile, the back door hinge reinforcing plate 3 is arranged in a hinge installation area 4 on the right side of the back door, and the back door inner plate 1, the back door hinge reinforcing plate 3 and the back door outer plate supporting plate 5 are sequentially attached and connected in the hinge installation area 4.

According to the side-opening back door reinforcing structure provided by the utility model, the back door outer plate supporting plate 5 extends to the hinge installation area 4 of the back door, and is sequentially attached and connected with the back door inner plate 1, the back door hinge reinforcing plate 3 and the back door outer plate supporting plate 5 in the hinge installation area 4 of the back door to form a three-layer plate connecting structure, so that the supporting rigidity of the hinge position of the side-opening back door can be improved, the sagging problem of the side-opening back door is solved, and the problem that the side of a door lock on the opposite side cannot be closed due to sagging deformation is avoided.

Alternatively, the three-layer plate connection mode of the back door inner plate 1, the back door hinge reinforcing plate 3 and the back door outer plate supporting plate 5 may be two-by-two welding, may be screw connection, may also be snap-fit connection, and the like.

The principle analysis on the problem of improving the sagging of the back door by constructing a three-layer plate connection to raise the support rigidity in the right side hinge mounting area 4 of the side-opening back door is as follows:

the factor that the back door sags is that the back door is opened to the side and is the cantilever state, and the back door is equivalent to the cantilever beam that uses the hinge as the fulcrum, and after the back door was opened, under the action of gravity of back door, the back door was used the hinge as the fulcrum to be the trend of downwarping, and back door hinged joint side is torn easily, and back door lock side sags very easily, causes cantilever end (lock side) sagging deformation, and the condition that the door lock can't close the lock with the dislocation.

The problem that the back door sags caused by cantilever state after the side-opening back door is opened is solved, three layers of plates are sequentially welded through the structure of the back door hinge installation area 4, the supporting rigidity of the back door hinge pivot point position is improved, the supporting rigidity is high at the back door hinge pivot point position, the back door is supported by high supporting force at the hinge pivot point position, the sagging gravity of the back door can be counteracted according to the principle of force balance, the balancing property of the back door after the side-opening back door is maintained, and therefore the problem of sagging of the side-opening back door is avoided.

In some embodiments, as shown in fig. 1 and 6, the outer back door panel support plate 5 is provided with a first connection position 501, and the first connection position 501 is located at the upper right side of the hinge mounting area 4, and the outer back door panel support plate 5, the hinge reinforcing plate 3 for the back door and the inner back door panel 1 are sequentially attached and connected at the upper right side of the upper hinge 6, so as to form a three-layer plate connection structure.

Similarly, the joint connection at the position where the first connection position 501 of the back door outer support plate 5 is located may also be a welding, screw connection or snap connection. When a soldered connection is used, a solder joint at the first connection site 501 is defined as a solder joint of the first three layers (the location indicated by the first connection site 501 in fig. 1).

Just like our daily common side is opened, because the side is opened the door and is sagged under the action of gravity, open the door in the side and use the back for a long time, go up hinge 6 and split very easily, lead to the side to open the door slope deformation, go up hinge 6's position and be the weak link of deformation. According to the embodiment, the back door outer plate supporting plate 5 extends to the upper right side of the upper hinge 6, the back door outer plate supporting plate 5, the back door hinge reinforcing plate 3 and the back door inner plate 1 are welded together in three layers at the position to form a first three-layer welding point, and the sagging rigidity of the side-opening back door is further improved through the additionally-arranged three-layer welding point, so that the sagging trend of the side-opening back door is improved, and the smoothness of side closing of the back door lock is further ensured.
