Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobiles, in particular to a connection structure with an increased offset bump. Background Art
[0002] With the rapid development of the automobile industry, automobiles play an irreplaceable role in people's lives. People are concerned not only about the good-looking appearance, but also the safety of automobiles. The A-pillar is one of the most important force-bearing parts in the body-in-white frame. It not only requires that the driver's living space can be effectively guaranteed after a certain impact, but also requires that after a collision, there should be no open welding, tearing, etc. between the sheet metals that cause secondary injuries to passengers and pedestrians. When the vehicle has a frontal offset collision, only by dispersing and absorbing the side collision force can the intrusion be effectively reduced, thereby reducing the damage to the door members. The EU regulations require that the speed of the offset collision is greater than 50Km / h, the impact toughness of the A-pillar must be greater than the impact energy, and it must be ensured that the A-pillar will not break and that there will be no tearing between the inner and outer panels of the A-pillar.
[0003] The traditional A-pillar structure has welding points that are prone to failure due to welding space and process reasons. When a collision occurs, welding cannot effectively prevent tearing.
[0004] Therefore, in order to solve the above problems, an A-pillar connection structure is designed to avoid tearing, ensure the safety performance of the vehicle body, and reduce the weight to the lightest while meeting the coating process requirements and performance requirements. Utility Model Content
[0005] The utility model aims to provide a connection structure with a simple structure, convenient installation, strong guiding property, light weight, avoiding tearing phenomenon and increasing offset collision to ensure the safety performance of the vehicle body.
[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0007] A connection structure, comprising an A-pillar reinforcement plate, an A-pillar inner plate, an A-pillar inner plate reinforcement plate, a dash plate, and a dash plate reinforcement plate, and further comprising:
[0008] An A-pillar connecting plate, the A-pillar connecting plate being covered at a welding point between the A-pillar reinforcement plate and the A-pillar inner plate;
[0009] The A-pillar connecting plate is fixedly connected to the A-pillar reinforcing plate and the front wall reinforcing plate by bolts respectively.
[0010] The A-pillar connecting plate is in a "X"-shaped structure;
[0011] The A-pillar connecting plate has a first connecting section, a second connecting section and a third connecting section which are integrally formed;
[0012] The second connecting section is located between the first connecting section and the third connecting section;
[0013] The first connecting section and the third connecting section are respectively attached to the outer sides of the A-pillar reinforcement plate and the front wall reinforcement plate;
[0014] The second connecting section is formed along the welding contour of the A-pillar reinforcement plate and the A-pillar inner plate;
[0015] The first connecting section, the third connecting section, the A-pillar reinforcement plate, and the front wall reinforcement plate are respectively provided with mounting holes;
[0016] Nuts are projected-welded into the mounting holes at corresponding positions and bolts are installed to form a fastened connection.
[0017] In the above technical solution, a connection structure of the utility model has the following beneficial effects:
[0018] The utility model designs a connection structure, which connects the lower part of the A-pillar and the front cabin assembly by adding an A-pillar connecting plate. When the car is hit or the welding point fails, it can effectively prevent the front cabin assembly and the lower part of the A-pillar from being torn apart and the front enclosure from invading the passenger cockpit, thereby improving the offset collision safety performance and ensuring the safety of the driver and passengers as much as possible.

[0031] An A-pillar connecting plate 6, the A-pillar connecting plate 6 is covered at a welding point between the A-pillar reinforcement plate 1 and the A-pillar inner plate 2;
[0032] The A-pillar connecting plate 6 is fixedly connected to the A-pillar reinforcement plate 1 and the front wall reinforcement plate 5 by bolts 7 respectively.
[0033] Specifically, a connection structure for increasing offset collision includes a body-in-white frame (A-pillar reinforcement plate 1, A-pillar inner plate 2, A-pillar inner plate reinforcement plate 3, front wall plate 4, front wall plate reinforcement plate 5), an A-pillar connecting plate 6 and bolts 7 for installation, the two sides of the A-pillar connecting plate 6 are respectively connected and fixed with the A-pillar reinforcement plate 1 and the front wall reinforcement plate 5 by bolts, and the middle part of the A-pillar connecting plate 6 is in accordance with the welding edge of the A-pillar reinforcement plate 1 and the A-pillar inner plate 2, which will not affect the implementation of the painting and gluing process in the production process of the body-in-white;
[0034] The position of the A-pillar connecting plate 6 is not limited to the installation and fixation with the A-pillar reinforcement plate 1 and the front panel reinforcement plate 5. The shape and installation position of the A-pillar connecting plate 6 can be adjusted according to the performance simulation analysis and the actual collision test results.
[0035] The A-pillar connecting plate 6 is in a "X" shape;
[0036] The A-pillar connecting plate 6 has an integrally formed first connecting section 61 , a second connecting section 62 and a third connecting section 63 ;

[0042] Specifically, the first connecting section 61, the second connecting section 62 and the third connecting section 63 are integrally formed to form an A-pillar connecting plate 6 with a "J"-shaped structure. The raised second connecting section 62 is formed along the welding edge of the A-pillar reinforcement plate 1 and the A-pillar inner plate 2.
