Description

Technical Field

[0001] The utility model belongs to the technical field of automobile body structure design, and in particular relates to an automobile side enclosure assembly. Background Art

[0002] The side assembly of the automobile includes the side outer panel, A-pillar, front fender and threshold structure, etc., which is an important part of the automobile body. Among them, the lower part of the A-pillar is the cross-connection part of multiple components such as the side outer panel, front fender and threshold beam. In order to meet the collision performance of the automobile, multiple reinforcement plates are generally added to the lower part of the A-pillar to ensure the strength and stiffness requirements. However, the added multiple reinforcement plates will form a certain electromagnetic shielding during the later electrophoretic coating process, resulting in a decrease in the electrophoretic effect in the cavity space between the A-pillar, reinforcement plate and side outer panel, making it difficult to ensure that the electrophoretic film thickness meets the standard, and ultimately resulting in a decrease in the corrosion resistance of the car body, shortening the service life of the car, and causing a huge waste of resources. In the related art, the electrophoretic effect is improved by opening holes in the reinforcement plate, but due to the need to ensure the structural strength requirements, too many holes cannot be opened, which leads to limited improvement effects; in some structures, the A-pillar cavity is ensured to be a dry area by blocking the rubber plate through the threshold design, manually sealing the bottom of the A-pillar, etc., but the consistency of the artificial sealing process control is poor, and there is a risk of water ingress due to poor sealing, which will also lead to a decrease in the corrosion resistance of the car body and shorten the service life of the car.

[0003] Therefore, it is necessary to provide a new automobile side panel assembly structure, which is required to be able to improve the corrosion resistance of the vehicle body and increase the service life of the vehicle while ensuring the strength and rigidity of the lower structure of the A-pillar.

[0016] In the automobile side panel assembly structure provided by the utility model, the structural strength and rigidity of the connection part of the lower part of the A-pillar can be effectively improved by forming a reinforcement cavity between the side panel outer plate and the lower part of the A-pillar, which is beneficial to ensuring the collision performance of the automobile; at the same time, by adding electrophoresis holes on the side panel outer plate, the electrophoresis effect of the A-pillar and the side panel outer plate in the reinforcement cavity space can be effectively guaranteed, and the thickness of the electrophoresis film can be guaranteed, which is beneficial to improving the corrosion resistance of the vehicle body and increasing the service life of the vehicle; of course, after the reinforcement cavity is formed between the side panel outer plate and the lower part of the A-pillar, it is beneficial to reduce the number of reinforcement parts in the lower part of the inner cavity of the A-pillar, simplify the internal structure of the A-pillar, thereby helping to reduce the battery shielding in the inner cavity of the A-pillar and improve the electrophoresis effect in the inner cavity of the A-pillar, and since the electrophoresis holes are opened on the side panel outer plate, it is also beneficial to reduce the number of openings on the A-pillar, thereby ensuring the structural strength of the A-pillar.

The electrophoretic hole 301; it can be understood that the "front" of the above-mentioned "front part" refers to the front direction of the front of the car, and the "outer" of the "outer side" refers to the side away from the center of the car as the outside. Specifically, the outer side of the A-pillar 2 here refers to the outer side of the car in the horizontal direction, and the "lower part" refers to the lower part in the vertical direction; the fixed connection mentioned above can be fixed by bolts or welding. It should be noted that in the electrophoretic coating process, certain electrophoretic holes will also be opened on the inner side of the car body, such as opening holes on the inner plate of the A-pillar, etc., which can be designed with reference to the existing car body structure and will not be repeated here;

[0026] In the above structural design, the reinforcement cavity 3a formed between the side outer panel 3 and the lower part of the A-pillar 2 can effectively improve the structural strength and rigidity of the connection part of the lower part of the A-pillar 2, which is beneficial to ensuring the collision performance of the vehicle; at the same time, the electrophoresis hole 301 added to the side outer panel 3 can effectively ensure the electrophoresis effect of the A-pillar 2 and the side outer panel 3 in the space of the reinforcement cavity 3a, and ensure the thickness of the electrophoresis film, which is beneficial to improving the corrosion resistance of the vehicle body and increasing the service life of the vehicle; of course, since the reinforcement cavity 3a is formed between the side outer panel 3 and the lower part of the A-pillar 2, it is beneficial to reduce the number of reinforcement parts in the lower part of the inner cavity of the A-pillar 2, simplify the internal structure of the A-pillar 2, thereby helping to reduce the battery shielding in the inner cavity of the A-pillar 2 and improve the electrophoresis effect in the inner cavity of the A-pillar 2, and since the electrophoresis hole 301 is opened on the side outer panel 3, it is also beneficial to reduce the number of openings on the A-pillar 2 and ensure the structural strength of the A-pillar 2.
