Description

Technical Field

[0001] The utility model relates to the technical field of automobile assembly, in particular to a novel automobile front anti-collision beam assembly. Background Art

[0002] Early cars only had a front anti-collision beam located on the front side of the frame, which was used to protect the components inside the car from damage or reduce damage when the vehicle collided, but lacked pedestrian protection. With the popularization of family cars, consumers are paying more and more attention to pedestrian protection safety. In order to protect pedestrian safety, a pedestrian protection structure is often installed on the front side of the front anti-collision beam. Since the two are two different components, not only can their respective performances not be fully utilized, but they are also easy to affect the space layout. Summary of the invention

[0003] In order to solve the above problems, the utility model provides a new type of automobile front anti-collision beam assembly, which can specifically adopt the following technical solutions:

[0004] The novel automobile front anti-collision beam assembly described in the utility model comprises an anti-collision beam main body which is processed by a strip-shaped continuous steel coil through a rolling process, a pedestrian protection beam with a cavity-type structure made of cold-rolled steel plate is welded to the front side of the anti-collision beam main body, a collapse hole is opened on the pedestrian protection beam, a sponge buffer layer and a bubble cotton buffer layer are sequentially arranged on the front side of the pedestrian protection beam, and the rear side of the anti-collision beam main body is connected to the vehicle body through an energy absorption box.

[0005] The anti-collision beam body includes a front panel, and two U-shaped cavities are arranged at intervals on the rear side of the front panel. The U-shaped cavities are formed by extending and winding from the top and bottom of the front panel to the rear side respectively, and the ends of each U-shaped cavity are closed and connected to the front panel by double welding or spot welding process.

[0006] The pedestrian protection beam is a rear-opening U-shaped structure, which is clamped on the front panel of the anti-collision beam body and is welded to the anti-collision beam body through a two-protection welding process.

[0007] The front plate, the top plate and the bottom plate of the pedestrian protection beam are all provided with circular through holes as the collapse holes.

[0008] The sponge buffer layer and the bubble cotton buffer layer are arranged on the front plate of the pedestrian protection beam.

[0009] There are two energy absorption boxes, which are symmetrically arranged at both ends of the anti-collision beam body.

[0010] The energy absorption box is composed of an upper energy absorption plate, a lower energy absorption plate, a front connecting plate and a rear connecting plate. The upper energy absorption plate and the lower energy absorption plate are snapped together to form a cavity prism. The edges and / or surfaces of the cavity prism are provided with crush inducing grooves. The two ends of the cavity prism are respectively welded to the front connecting plate and the rear connecting plate, and the front connecting plate is welded to the anti-collision beam main body, and the rear connecting plate is connected to the vehicle body by bolts.

[0011] The new automobile front anti-collision beam assembly provided by the utility model has a simple structure, low cost, is easy to manufacture and install, and adopts an integrated design of installing a pedestrian protection structure on the front side of the front anti-collision beam, which can not only enhance the anti-collision performance of the vehicle itself, but also maximize the safety of the driver and pedestrians when an accident occurs, and the performance is more optimized, achieving the effect of "1+1>2"; at the same time, the integrated design makes it unnecessary to consider the pedestrian protection part of the front grille of the vehicle, and can leave a lot of space for modeling and layout, thereby optimizing the overall structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 It is a structural schematic diagram of the utility model.

[0013] Figure 2 yes Figure 1 Schematic diagram of the decomposition structure. DETAILED DESCRIPTION

[0014] The following is a detailed description of an embodiment of the utility model in conjunction with the accompanying drawings. This embodiment is implemented on the premise of the technical solution of the utility model, and a detailed implementation method and a specific working process are given, but the protection scope of the utility model is not limited to the following embodiment.

[0015] like Figure 1-2 As shown, the new automobile front anti-collision beam assembly described in the utility model includes an anti-collision beam main body 1 which is processed by a strip-shaped continuous steel coil through a rolling process, a pedestrian protection beam 2 with a cavity-type structure made of cold-rolled steel plate is welded to the front side of the anti-collision beam main body 1, a collapse hole 21 is opened on the pedestrian protection beam 2, a sponge buffer layer 3 and a bubble cotton buffer layer 4 are sequentially arranged on the front side of the pedestrian protection beam 2, and the rear side of the anti-collision beam main body 1 is connected to the vehicle body through an energy absorption box 5.

[0016] Specifically, the anti-collision beam body 1 includes a front panel 11, and two U-shaped cavities 12 are spaced apart on the rear side of the front panel 11. Each U-shaped cavity 12 is formed by extending and winding from the top or bottom of the front panel 11 to the rear side, and the end of each U-shaped cavity 12 is closed and connected to the front panel 11 by double welding or spot welding process.

[0017] The pedestrian protection beam 2 is a rear-opening U-shaped structure, which is clamped on the front panel 11 of the anti-collision beam body 1 and is welded to the anti-collision beam body 1 through a two-welding process. Since the cavity-shaped structure is made of cold-rolled steel plate, it has high strength and good toughness. At the same time, circular through holes are opened on the front plate, top plate and bottom plate of the pedestrian protection beam 2 as collapse holes 21, which can not only reduce weight, but also absorb part of the impact force of the collision.

[0018] The sponge buffer layer 3 and the bubble cotton buffer layer 4 are similar in shape to the front plate of the pedestrian protection beam 2 . The sponge buffer layer 3 is attached to the front plate of the pedestrian protection beam 2 , and the bubble cotton buffer layer 4 is attached to the sponge buffer layer 3 .

[0019] There are two energy absorption boxes 5 with the same structure, which are symmetrically installed at the two ends of the anti-collision beam body 1. Each energy absorption box 5 is composed of an upper energy absorption sheet 51, a lower energy absorption sheet 52, a front connecting plate 53 and a rear connecting plate 54, wherein the upper energy absorption sheet 51 and the lower energy absorption sheet 52 are connected together to form a hollow prism, and the edges and / or surfaces of the hollow prism are provided with crush inducing grooves 55, and the two ends are respectively welded to the front connecting plate 53 and the rear connecting plate 54. The above-mentioned front connecting plate 53 is welded to the anti-collision beam body 1, and the rear connecting plate 54 is connected to the vehicle body by bolts.

[0020] When an accident occurs, the victim first comes into contact with the bubble cotton cushioning layer 4, which acts as the first layer of cushioning; then the pressure is transmitted to the sponge cushioning layer 3, which further reduces the cushioning. Since the sponge cushioning layer 3 will be compressed and hardened after being squeezed, it can be used as a protective layer for the collision part of the human body, which is equivalent to adding a layer of "quilt" between the collision part of the victim's body and the pedestrian protection beam 2; thereafter, the pressure is transmitted to the pedestrian protection beam 2 made of cold-rolled steel plate, which is a cavity structure with a thin material thickness and good toughness; the beam body is provided with a collapse hole 21, which is deformed again after contacting the victim wrapped in the "quilt", and at the same time absorbs a large part of the impact force generated by the collision. The deformed pedestrian protection beam 2 again provides the victim with a protective layer of metal material, which greatly increases the safety protection for the victim; finally, it reaches the anti-collision beam body 1. At this time, the victim already has the multi-layer protection formed previously, and the damage suffered after colliding with the anti-collision beam body 1 with higher strength and hardness will be greatly reduced, thereby protecting the personal safety of the victim to a great extent.

[0021] It should be noted that, in the description of the present invention, terms indicating orientation or positional relationships, such as "front", "rear", "left", "right", "vertical", "horizontal", "inside", "outside", etc., are based on the orientation or positional relationships shown in the drawings and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
