[0006] The automobile front bumper beam reinforcement structure comprises a front bumper beam body and an energy absorption box. The energy absorption box is arranged corresponding to the edge of the front bumper beam body. The front bumper beam body is a hollow structure. A reinforcement structure is arranged in the edge cavity of the front bumper beam body.

[0007] Further:

[0008] The reinforcement structure is arranged corresponding to the front end of the energy absorption box.

[0009] The reinforcement structure is a hollow reinforcement tube.

[0010] Reinforcement pipes are arranged on both sides of the front protection cross beam body.

[0011] The reinforcement tube is fixed in the front guard cross beam body by a group of fastening rivet screws.

[0012] The reinforcement tubes in the two side parts are arranged symmetrically.

[0013] The front protection cross beam body is provided with a group of cavities in the vertical direction, and the reinforcement tube is arranged in the uppermost cavity.

[0014] Compared with the prior art, the utility model has the following advantages:

[0015] The car's front anti-collision beam reinforcement structure is reasonably designed. The reinforced structure inside the edge of the front anti-collision beam body can better resist the collision force and prevent it from bending prematurely, making the induction of the rear energy absorption box more stable, giving full play to the energy absorption effect of the front anti-collision beam body, better preventing deformation of the passenger compartment and ensuring the safety of the passengers.

[0024] The specific implementation of the utility model will be further explained in detail below through the description of embodiments with reference to the accompanying drawings.

[0025] like Figures 1 to 5 As shown, the automobile front bumper beam reinforcement structure includes a front bumper beam body 1, an energy absorption box and a reinforcement structure; a pair of energy absorption boxes are arranged corresponding to the edges of the front bumper beam body 1, the front bumper beam body is a hollow structure, and the reinforcement structure is arranged in the edge cavity of the front bumper beam body.

[0026] The reinforcement structure is arranged at the front end of the energy absorption box. The reinforcement structure is a hollow reinforcement tube. The reinforcement tube is built into the cavity of the front bumper beam body 1 and has a compact structure. The reinforcement tube is a hollow structure and is light in weight, which is conducive to lightweight design.

[0027] Reinforcing tubes are provided on both side portions of the front bumper cross member body 1. The two reinforcing tubes are respectively a side reinforcing tube 2 and the other side reinforcing tube 3; a pair of energy-absorbing boxes are respectively a side energy-absorbing box 5 and the other side energy-absorbing box 6; the rear end of the side energy-absorbing box is connected to the side end plate 7, the front end of the side energy-absorbing box is connected to the front bumper cross member body, and the side reinforcing tube is correspondingly arranged with the front end of the side energy-absorbing box; the rear end of the other side energy-absorbing box is connected to the other side end plate 8, the front end of the other side energy-absorbing box is connected to the front bumper cross member body, and the other side reinforcing tube is correspondingly arranged with the front end of the other side energy-absorbing box.
