Description

Technical Field

[0001] This utility model relates to the field of automobile body, and in particular to an automobile top side beam assembly structure. Background Technology

[0002] New energy vehicles, with their advantages of energy conservation and environmental protection, have become a hot research topic in the automotive field. Currently, a common challenge in the electric vehicle sector is the limited driving range of electric vehicle batteries, which restricts their widespread application. Current automotive roof beams primarily use stamped steel parts, which are difficult to form, costly to invest in, and detrimental to the lightweighting of electric vehicles and extending their driving range. Furthermore, to meet collision requirements, the roof beam assembly is heavy, and the manufacturing, assembly, and maintenance costs of the metal parts are all high. Therefore, there is a need to invent a new automotive roof beam assembly structure. Utility Model Content

[0003] The purpose of this invention is to provide a new automotive top side beam assembly structure that addresses the problems of high weight and high production cost of existing top side beam assembly structures.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

A first reinforcing rib is fixedly disposed in the first cavity and is fixedly connected to the two inner side walls of the first cavity. An upper A-pillar reinforcing plate is fixedly connected to the upper part of the outer A-pillar panel, and an upper A-pillar connecting plate is fixedly connected to the roof beam and the upper A-pillar inner panel.

[0006] Preferably, in conjunction with the above scheme, a number of sets of second reinforcing ribs are also fixedly connected at intervals on the inner wall of the first cavity.

[0007] Preferably, in combination with the above scheme, each group of second reinforcing ribs is fixedly connected to only one inner wall of the first cavity.

[0008] Preferably, in conjunction with the above scheme, the first reinforcing rib is inclined toward the inside of the vehicle.

[0009] Preferably, in conjunction with the above scheme, the reinforcing plate on the A-pillar is fixedly connected to the inner wall of the outer plate of the A-pillar by welding.

[0010] Preferably, in conjunction with the above scheme, the connecting plate on the A-pillar is fixedly connected to the front part of the top side beam and the rear part of the inner panel of the upper A-pillar, respectively, and the connecting plate on the A-pillar is fixedly connected to the side of the top side beam and the inner panel of the upper A-pillar facing the inside of the vehicle.

[0011] Preferably, in combination with the above scheme, the connecting plate on the A-pillar is fixedly connected to the inner plate of the upper A-pillar to form a second cavity inside.

[0012] Preferably, in conjunction with the above scheme, the inner wall of the outer panel of the A-pillar is fixedly connected to the side wall of the top edge beam facing outwards from the vehicle, and the outer wall of the connecting plate on the A-pillar is fixedly connected to the side wall of the top edge beam facing inwards from the vehicle.

[0025] like Figures 1 to 4 The diagram illustrates a car roof beam assembly structure, comprising a roof beam 1, an outer A-pillar panel 2, and an inner upper A-pillar panel 3. The roof beam 1 is made of 6-series aluminum alloy with an irregular cross-section. A first cavity 10 is provided within the roof beam 1, and a first reinforcing rib 11 is fixedly disposed within the first cavity 10, dividing the first cavity 10 into two independent cavities. The first reinforcing rib 11 is fixedly connected to the two inner sidewalls of the first cavity 10. An upper A-pillar reinforcing plate 4 is fixedly connected to the upper part of the outer A-pillar panel 2. The roof beam 1 and the inner upper A-pillar panel 3 are fixedly connected via an upper A-pillar connecting plate 5. Several rivet holes on the upper A-pillar connecting plate 5, and corresponding rivet holes on the roof beam 1, are used for riveting and assembly with the front roof crossbeam. The outer A-pillar panel 2 can be made of CR950 / 1300HS material; the inner A-pillar panel 3 can be made of HC340 material; the upper A-pillar reinforcing plate 4 can be made of CR950 / 1300HS material; and the upper A-pillar connecting plate 5 can be made of HC340 material.

[0026] To increase the structural stiffness of the top edge beam 1, such as Figure 5 As shown, several sets of second reinforcing ribs 12 are also fixedly connected at intervals on the inner wall of the first cavity 10.

[0027] To avoid obstructing the bolt mounting holes 13 and other bolt mounting positions on the top edge beam 1, such as... Figure 5 As shown, each set of second reinforcing ribs 12 is fixedly connected to only one inner wall of the first cavity 10.

[0028] In order to meet the strength requirements for side collisions, the first reinforcing rib 11 is inclined towards the inward direction of the vehicle.

[0029] To facilitate the fixing of the upper reinforcing plate 4 of the A-pillar to the outer plate 2 of the A-pillar, such as Figure 8 As shown, the A-pillar upper reinforcing plate 4 is fixedly connected to the inner side wall of the upper part of the A-pillar outer plate 2 by welding. The cross-section of the A-pillar upper reinforcing plate 4 is a "U" shaped structure, which follows the shape of the inner side wall of the A-pillar outer plate 2.

[0030] To better connect and reinforce the front part of the top edge beam 1 with the rear part of the inner plate 3 of the upper A-pillar, such as... Figure 2 As shown, the connecting plate 5 on the A-pillar is fixedly connected to the front part of the top side beam 1 and the rear part of the inner plate 3 of the upper A-pillar, respectively. The connecting plate 5 on the A-pillar is fixedly connected to the side of the top side beam 1 and the inner plate 3 of the upper A-pillar facing the inside of the vehicle.

[0031] To increase structural stiffness, such as Figure 7 As shown, the connecting plate 5 on the A-pillar is fixedly connected to the inner plate 3 of the upper A-pillar to form a second cavity 20 inside.

[0032] To better secure the top edge beam 1 to the outer plate 2 of the A-column and the connecting plate 5 on the A-column, such as... Figure 6 As shown, the inner wall of the outer A-pillar panel 2 is fixedly connected to the side wall of the top beam 1 facing outwards from the vehicle, and the outer wall of the connecting plate 5 on the A-pillar is fixedly connected to the side wall of the top beam 1 facing inwards from the vehicle.

[0033] To ensure the structural rigidity of the A-pillar assembly, such as Figure 9 As shown, the outer A-pillar panel 2 and the inner A-pillar panel 3 are fixedly connected to form a third cavity 30 inside.
