As shown in fig. 1 to 4, the embodiment of the utility model provides a front lower protection for an automobile, which is characterized by comprising a beam body 1, an inclined support 2, a guard plate 3, an intermediate support 4 and a mounting bracket 5.
Continuing to refer to fig. 1, two mounting brackets 5 are arranged on the cross beam body 1, the two mounting brackets 5 are symmetrically arranged on the inner side of the cross beam body 1, and the two mounting brackets 5 are respectively used for being connected with left and right longitudinal beams of a vehicle. In practical application, two mounting brackets 5 are symmetrically arranged on the inner side of the cross beam body 1, namely, on the side of the cross beam body 1 facing the vehicle body, and the two mounting brackets 5 are respectively used for being connected with left and right longitudinal beams of the vehicle. When the vehicle is assembled, vehicles of different models can meet the installation of front lower protection by replacing the mounting bracket 5, so that the universality of the front lower protection is higher, and the cost is relatively lower.
As shown in fig. 2, the cross-sectional shape of the beam body 1 in the direction perpendicular to the longitudinal direction thereof is a japanese letter. The cross-sectional shape of the beam body 1 in the direction perpendicular to the direction in which the length thereof extends is set to be a shape of a Chinese character ri, so that the overall rigidity of the beam body 1 is enhanced and the support reaction force is increased.
In practical application, the end face of the first side of the diagonal support 2 is connected with the mounting bracket 5. The end surface of the second edge adjacent to the first edge of the inclined support 2 is connected with the beam body 1. And the inclined supports 2 are respectively positioned on one side of the corresponding mounting bracket 5 close to the end part of the beam body 1. The inclined support 2 can support the mounting bracket 5, the strength of the mounting bracket 5 can be improved, meanwhile, the strength of the beam body 1 can be improved, and therefore the overall strength of the front lower protection is improved.
Specifically, the guard plate 3 is connected to the cross beam body 1 and is located between the mounting bracket 5 and the cross beam body 1. The guard plate 3 is arranged to increase the direct contact area between the mounting bracket 5 and the beam body 1, so that the problem that the beam body 1 is stressed greatly due to the fact that the direct contact area between the mounting bracket 5 and the beam body 1 is too small is avoided, and the risk of local deformation of the beam body 1 is reduced.
Further, the middle support 4 is arranged on the inner side of the beam body 1, and two ends of the middle support are pressed by the corresponding inclined supports 2 after respectively penetrating through the corresponding mounting brackets 5. The middle support 4 can improve the strength of the middle part of the beam body 1, and meanwhile, two ends of the middle support 4 are pressed by the corresponding inclined supports 2 after respectively penetrating through the corresponding mounting brackets 5, so that the phenomenon that the local strength of the beam body 1 is weakened can be avoided.
In practical application, the two ends of the beam body 1 are arc-shaped, the inclined supports 2 are arranged in the arcs, the strength of the arcs at the two ends of the beam body 1 can be effectively improved, and the overall strength of the beam body 1 is improved through the arrangement of the intermediate supports 4. The crossbeam body 1, the inclined strut 2 and the middle support 4 are connected, so that the crossbeam body 1, the inclined strut 2 and the middle support 4 are integrated, and the strength of the crossbeam body 1 is greatly improved.
Specifically, the beam body 1, the inclined supports 2, the guard plate 3, the intermediate support 4 and the mounting bracket 5 are made of super-strong steel. Because the rigidity of the super-strong steel is higher than that of the carbon steel, when the super-strong steel is used, the strength requirement of front lower protection can be met when the thicknesses of the beam body 1, the inclined support 2, the guard plate 3, the middle support 4 and the mounting bracket 5 are set to be thinner, the whole weight of the front lower protection is reduced, the light weight of a vehicle is realized, meanwhile, the processing materials can be saved, and the production cost and the use cost of a user are reduced.
The embodiment of the utility model provides a front lower protection for an automobile, which comprises a beam body 1, an inclined support 2, a guard plate 3, a middle support 4 and a mounting bracket 5. Two mounting brackets 5 are arranged on the beam body 1, the two mounting brackets 5 are symmetrically arranged on the inner side of the beam body 1, and the two mounting brackets 5 are respectively used for being connected with left and right longitudinal beams of a vehicle.

With continued reference to fig. 3, the intermediate support 4 is of a corrugated configuration. Corrugated structure rigidity is higher than other structural rigidity, and intensity is better, therefore can improve the intensity of crossbeam body 1 middle part, and then improves the intensity of protection down in the front.
