Description

TECHNICAL FIELD

[0001] The utility model relates to the field of automobile crash beam, specifically relates to a high-strength aluminium profile for automobile. BACKGROUND

[0002] The automobile crash beam is a device for reducing the energy absorption when the vehicle is collided, which comprises an energy absorption box and a beam body, the energy absorption box absorbs kinetic energy, the beam body bears the force generated by the collision, thereby playing a protective role, as the main stress point, the beam body needs to have high strength, the existing aluminium profile for preparing the beam body is a hollow structure, and the strength is insufficient. SUMMARY

[0003] The utility model solves the technical problem in view of the insufficient of prior art,

[0004] Provide a kind of high-strength aluminium profile for automobile, improve structural strength.

[0005] To achieve the above object, the utility model provides the following technical scheme: a kind of high-strength aluminium profile for automobile, it is characterized by: including oppositely arranged first plate body, two the first plate body center vertical connection is equipped with second plate body, the first plate body and second plate body form the support of "H" type, the support is coaxially provided with the cylindrical shell of second plate body around, each the first plate body radial two ends are connected with the hollow inner wall of cylindrical shell.

[0006] The utility model with above-mentioned characteristics: "H" type support supports cylindrical shell, increases its strength, and the camber of cylindrical shell is higher in deformation resistance when being impacted, and the strength is higher.

[0007] The utility model further provides: the radial width of the first plate body is equal to the sum of the thickness of two first plate bodies and the radial width of second plate body.

[0008] The utility model with above-mentioned characteristics: support and cylindrical shell are tangent, so that stress is uniform.

[0009] The utility model further provides: the outer side end surface of cylindrical shell is connected with seat plate, and the seat plate is parallel to second plate body.

[0010] The utility model with above-mentioned characteristics: seat plate is convenient for the installation of energy absorption box.

[0011] The utility model further provides: support plate is oppositely arranged between the seat plate and the outer side end surface of cylindrical shell.

[0012] The utility model with above-mentioned characteristics: support plate increases the reliability of seat plate and cylindrical shell connection.

[0013] The utility model further sets up: first board body, second board body, cylinder shell, seat board and support board are integrally formed.

[0014] The utility model has the characteristics of: increase structural strength.

[0015] The utility model has the advantages of: H type support spare supports cylinder shell, increases its strength, and the arc surface of the cylinder shell is higher in anti-deformation ability and higher in strength when being impacted.

[0016] The utility model will be further explained in detail in connection with the drawings and examples. DRAWINGS
