Description

Technical Field

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

[0002] With the popularization of automobiles, people's requirements for automobile safety are getting higher and higher. As a key component affecting vehicle collision safety, the layout of the front subframe anti-collision beam and the design of its structure play a decisive role in the collision safety performance of the automobile. The anti-collision beam is a device used to absorb collision energy when the vehicle is impacted. It consists of a main beam, an energy-absorbing box, and a mounting plate connecting the automobile. Both the main beam and the energy-absorbing box can effectively absorb collision energy during a low-speed collision of the vehicle, minimizing the damage to the vehicle's longitudinal beam caused by the impact force as much as possible, thus playing its protective role for the vehicle.

[0003] For the consideration of the collision safety of the chassis system, in the prior art, an anti-collision beam is often welded and fixedly connected to the front end of the front subframe or longitudinal beam of the automobile. Its structure is a pipe with a circular cross-section, or a beam with a "mouth" - shaped cross-section formed by welding two stamping parts with a "U" - shaped cross-section after being buckled.

[0004] For the anti-collision beam in the prior art, the anti-collision beam is integrally and fixedly connected to the subframe. No matter how much the anti-collision beam deforms, the entire anti-collision beam usually needs to be replaced during maintenance, increasing the maintenance cost. Many anti-collision beams only set their cross-sections as "day" - shaped or other shapes to improve strength, but the buffering ability of the anti-collision beam itself is not good. Content of the Utility Model

[0005] The purpose of the utility model is to solve the defects existing in the prior art, and to propose an automobile front anti-collision beam.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme: An automobile front anti-collision beam includes a mounting plate. A collision beam main body is fixedly connected to the surface of the mounting plate. A groove is formed on the surface of the collision beam main body. A front anti-collision plate is inserted into the collision beam main body through the groove. A matching hole is fixedly connected to the upper surface of the front anti-collision plate. A bolt is inserted into the inner wall of the matching hole. A threaded hole is fixedly connected to the upper surface of the mounting plate. A rib plate is fixedly connected to the inner wall of the collision beam main body. A weight-reducing hole is formed on the surface of the rib plate. The weight-reducing holes are evenly distributed. A support rod is fixedly connected to the surface of the rib plate. A buffer strip is fixedly connected to the upper surface of the front anti-collision plate. A cavity is arranged inside the buffer strip. An installation hole is formed on the surface of the mounting plate.

[0007] As a further description of the above technical solution:

[0008] Both the threaded hole and the matching hole are symmetrically distributed, and the position of the threaded hole is adapted to the matching hole.

[0010] The shape of the upper surface of the mounting plate is adapted to the anti-collision front plate, and the mounting plate is fixedly connected to the anti-collision front plate through the cooperation of screw holes, bolts and matching holes.

[0011] As a further description of the above technical solution:

[0012] The inner wall of the anti-collision beam body is fixedly connected to the support rods, and the support rods are evenly distributed on the inner wall of the anti-collision beam body.

[0013] As a further description of the above technical solution:

[0014] The support rod is provided with an inclination angle, and the surfaces of the mounting plate, the anti-collision beam body and the anti-collision front plate are all electroplated with an anti-oxidation coating.

[0015] As a further description of the above technical solution:

[0016] The shape of the buffer strips is adapted to the anti-collision front plate, and the buffer strips are distributed at equal intervals.

[0017] The utility model has the following beneficial effects:

[0018] 1. Compared with the prior art, the front anti-collision beam of a car performs the first step of buffering by deforming the buffer strip, the anti-collision front plate will deform, the second step of buffering will be performed, the anti-collision beam body will deform, and the rib plate will deform at the same time. The deformation of the rib plate will force the support rod to deform, and the third step of buffering will be performed, thereby improving the buffering effect of the utility model when used and being able to better protect the vehicle.

[0019] 2. Compared with the prior art, after a minor collision, if the main body of the anti-collision beam is found to be deformed during maintenance, it is only necessary to remove the bolts and replace them with new anti-collision front plates and bolts, thereby reducing maintenance costs.

[0020] 3. Compared with the prior art, this automobile front anti-collision beam is provided with weight-reducing holes, ribs and support rods. The cooperation of the ribs and support rods can effectively improve the strength of the anti-collision beam body, and the weight-reducing holes can reduce the weight of the overall structure.

[0031] The inner wall of the anti-collision beam body 2 is fixedly connected with a rib plate 7, and the surface of the rib plate 7 is provided with weight-reducing holes 12, which are evenly distributed and can reduce the weight of the overall mechanism. The shape of the rib plate 7 is adapted to the anti-collision beam body 2, and the surface of the rib plate 7 is fixedly connected with a support rod 8. When the rib plate 7 is deformed, the support rod 8 will be driven to deform, thereby improving the buffering effect. The upper surface of the anti-collision front plate 3 is fixedly connected with a buffer strip 9, and the shape of the buffer strip 9 is adapted to the anti-collision front plate 3. The buffer strips 9 are evenly distributed, and a cavity 10 is provided inside the buffer strip 9. When the buffer strip 9 is deformed, the air in the cavity 10 is further compressed to absorb the impact force, and the first step of buffering is performed. The surface of the mounting plate 1 is provided with mounting holes 11, and the mounting holes 11 are evenly distributed. The energy absorption box is installed through the mounting holes 11;

[0032] The inner wall of the anti-collision beam body 2 is fixedly connected to the support rod 8, and the support rod 8 is evenly distributed on the inner wall of the anti-collision beam body 2. The support rod 8 is set with an inclination angle, so that the support rod 8 is easy to deform, thereby improving the buffering capacity.

[0033] Working principle: When the utility model is used, the energy absorption box is first installed through the installation hole 11, and then the whole is installed. When a collision occurs, the buffer strip 9 is generally the first to be stressed, and the buffer strip 9 is deformed to further compress the air in the cavity 10, absorbing the impact force, and performing the first step of buffering to reduce the stress on the anti-collision front plate 3 and the anti-collision beam body 2. If the first step of buffering fails to offset the impact force, the anti-collision front plate 3 will be deformed to absorb the impact force, and the second step of buffering will be performed. If the second step of buffering still fails to offset the impact force, the anti-collision beam body 2 will be deformed and the rib plate 7 will be deformed at the same time. The deformation of the rib plate 7 will force the support rod 8 to deform, and the third step of buffering will be performed. If the anti-collision beam body 2 is found to be deformed during maintenance, it is only necessary to remove the bolts 5 and replace the new anti-collision front plate 3 and bolts 5, thereby reducing maintenance costs.
