Description

Reinforcing structure at the hinge installation of the inner door panel

technical field

The invention belongs to the technical field of automobile manufacturing, and in particular relates to a reinforcement structure for a hinge installation place of an inner panel of a car door.

Background technique

The door hinge is a key part connecting the car body and the door. The door can be opened or closed by rotating around the hinge axis. When the door is opened, the weight of the door will be completely borne by the hinge. increase, the plate at the hinge installation place on the door will deform, and the door will sag to a certain extent, which will directly affect the cooperation between the door and the body, the door will rub against the body, there will be abnormal noise when the door is opened and closed, and the door and the Paint peeling due to body interference.

Contents of the invention

The invention provides a reinforcing structure at the hinge installation place which improves the local rigidity of the vehicle door.

In order to achieve the above purpose, the technical solution adopted is: a reinforced structure for the installation of the hinge of the inner panel of the car door, the front panel and the side panel of the front part of the inner panel of the door are arranged successively at an angle, and the hinge installation hole is opened on the front panel. A reinforcement plate is arranged on the inner side plate surface of the junction of the front plate and the side plate at the hinge mounting hole.

Compared with the prior art, the technical effect of the present invention is: by arranging a reinforcing plate on the inner side of the junction of the front panel and the side panel, the local rigidity of the door can be ensured, and the anti-sagging performance of the door can be improved.

Detailed ways

A reinforced structure for the hinge installation of the inner panel of the car door. The front panel 11 and the side panel 12 at the front of the inner panel 10 of the car door are arranged in an angled sequence with each other. The hinge installation hole 14 is opened on the front panel 11. A reinforcement plate is provided on the inner side of the junction of the front panel 11 and the side panel 12. A reinforcing plate is set on the inner side panel of the car door to ensure the local rigidity of the car door and improve the anti-sag performance of the car door.

Further, there is a front side panel 13 extending forward at the front edge of the front panel 11, and a reinforcing plate is arranged on the inner side panel at the junction of the front panel 11 and the front side panel 13, and the panel surface of the front side panel 13 is in contact with the front side panel 13. The board faces of the side boards 12 are consistent.

Arrange the above two reinforcing plates in an integrated structure, that is, the reinforcing plate is arranged forward from the joint of the front plate 11 and the side plate 12 to the joint of the front plate 11 and the front side plate 13, which can greatly improve the local Stiffness and anti-sag performance of the door.

In order to ensure the anti-sagging performance of the car door, the additional reinforcement plate is thicker and has a larger area. The reinforcement plate of the present application is arranged with a tongue plate 21 extending forward from the junction of the front plate 11 and the side plate 12. The tongue plate 21 The board surface and the inner board surface of front side panel 13 lean against. Through the setting of the tongue plate 21, it is possible to meet the local rigidity of the hinge installation while reducing the thickness of the reinforcement plate body and the area of the reinforcement plate. On the one hand, the material consumption of the reinforcement plate is greatly reduced, which saves the manufacturing cost of the vehicle; on the other hand On the one hand, it will reduce the weight of the vehicle to a certain extent and improve the fuel economy of the vehicle.

The reinforcing plate includes a lower reinforcing plate 23, the lower plate body of the side plate 12 is provided with a speaker mounting hole 30, and the lower reinforcing plate 23 extends from the junction of the front plate 11 and the side plate 12 to the side of the outer periphery of the speaker mounting hole 30. plate 12. The junction of the front plate 11 and the side plate 12 is adjacent to the speaker installation hole 30, so the lower reinforcing plate 23 can greatly increase the height of the speaker installation hole 30 as long as it extends to the side plate 12 of the outer periphery of the speaker installation hole 30. The strength of the body ensures that the speaker can be installed reliably.

Further, the speaker installation hole 30 is a stepped hole, and the lower reinforcing plate 23 extends to the stepped surface of the speaker installation hole 30 .

The upper and lower sides of the lower reinforcing plate 23 have flanges 231 arranged away from the inner panel 10 of the vehicle.

The reinforcing plate also includes an upper reinforcing plate 22, and the upper, lower and rear sides of the reinforcing plate 22 all have outer flanges 221 arranged away from the inner panel 10 of the vehicle.

In order to facilitate the installation of the hinge mounting plate 50, two bayonet sockets 24 are arranged at intervals on the surface of the reinforcing plate, and the opening directions of the two bayonet sockets 24 are in opposite directions. In this way, the hinge mounting plate 50 can be initially positioned, which facilitates the welding of the reinforcing plate and the hinge mounting plate 50 in the later stage.

On the front plate 11 between the upper and lower reinforcement plates 22 and 23 of the reinforcement plate, a limiter installation hole 40 is provided, and the limiter installation hole 40 places is provided with a limiter reinforcement plate 41, and on the limiter reinforcement plate 41 The provided through hole corresponds to the stopper installation hole 40 .
