The technical scheme of the utility model is described in detail below with reference to the specific drawings.

Example 1

Referring to fig. 1 and 2, a front cabin side beam is disposed on a vehicle body of an automobile. The front cabin side sill includes: the front cabin edge beam body 11 and the reinforcement beam 112, wherein, as will be understood by those skilled in the art, the front cabin edge beam body 11 serves as a base of the front cabin edge beam, and the reinforcement beam 112 serves as a reinforcement for reinforcing the overall strength of the front cabin edge beam body 11.

As a preferred technical solution, the front cabin edge beam body 11 extends along a first direction, and in this embodiment, the front cabin edge beam body 11 is preferably provided with a plurality of cavities 111 (as shown in fig. 1, this embodiment is illustrated by taking three cavities 111 as an example), each cavity 111 extends along the first direction, and each cavity 111 is sequentially arranged from top to bottom along a second direction, where the first direction and the second direction are mutually perpendicular.

The reinforcing beam 112 extends along the first direction, and the reinforcing beam 112 is inserted into one of the cavities 111, and the reinforcing beam 112 is used for reinforcing the strength of the front cabin edge beam 11. In the present embodiment, taking fig. 1 as an example, the first direction is set as the direction in which the front side rail body 11 extends from the head to the tail, and the second direction is set as the direction perpendicular to the first direction. The first and second directions in this embodiment are only for clearly describing the contents of this embodiment. Meanwhile, in the present embodiment, the second direction is preferably a vertical direction as shown in fig. 1. By providing different numbers of the cavities 111, the strength of the cabin edge beam main body 11 can be improved.

As shown in fig. 3, the reinforcement beam 112 is provided with a notch 113, and the notch 113 is used for guiding the crumple deformation tendency of the front cabin side beam 11 when being collided. The notch 113 is located on both side walls of the reinforcement beam 112 parallel to the second direction.

If the reinforcing beam 112 is not notched, the strength of the reinforcing beam 112 is uniform throughout, and the collision collapse direction and the deformation direction cannot be accurately expected, which may cause unexpected safety problems. Due to the notch 113, there is a relatively weak stress area on the reinforcement beam, and the area is relatively weak, and can be preferentially crushed after being impacted, as shown in fig. 3, the area is preferentially crushed and absorbed along the length direction, i.e. the first direction, of the reinforcement beam 112, so as to guide the collision and crush direction, and improve the robustness of the collision and energy absorption process. And meanwhile, the normal use of other parts is prevented from being influenced by the collapsing deformation.

With continued reference to fig. 1 and 2, the number of cavities 111 in the forward cabin edge beam body 11 is preferably three, with the stiffening beam 112 being located in the lowermost cavity 111. In this embodiment, the number of the reinforcing beams 112 is set in the lowermost cavity 111, and one reinforcing beam is required, and in specific use or other embodiments, the number of the reinforcing beams 112 may be increased or decreased according to specific use requirements; and any one of the three cavities 111 may be placed.

Referring to fig. 2, the cross sections of the reinforcing beam 112 and the cavity 111 in the second direction are in a square structure as a whole; meanwhile, the outer walls of the two sides of the reinforcing beam 112 parallel to the second direction are respectively clung to and fixedly connected with the inner walls of the two sides of the bottommost cavity 111 parallel to the second direction. The outer wall of the reinforcing beam 112 is tightly attached to the inner wall of the cavity 111, so that the reinforcing beam 112 is ensured to be stable in the cavity 111, and looseness is avoided.

In the second direction, the outer wall of one side of the reinforcing beam 112 is fixedly connected with the inner wall of one side of the cavity 111, and a gap exists between the outer wall of the other side of the reinforcing beam 112 and the inner wall of the other side of the cavity 111; the outer walls of the other two sides of the reinforcing beam 112 parallel to the second direction are respectively clung to and fixedly connected with the inner walls of the two outer two sides of the cavity 111. Specifically, the lower outer wall of the reinforcement beam 112 is fixedly connected to the lower inner wall of the lowermost cavity 111, and a gap exists between the upper outer wall of the reinforcement beam 112 and the upper inner wall of the lowermost cavity 111.

The lower outer wall of the reinforcement beam 112 is fixedly connected with the lower inner wall of the lowermost cavity 111 by structural adhesive and blind rivets 122. In the second direction, the outer wall of one side of the reinforcing beam 112 is fixedly connected with the inner wall of one side of the cavity 111 by structural adhesive and blind rivets 122.

The fixed connection between the outer walls of the lower side of the reinforcing beam 112 and the inner walls of the lower side of the cavity 111 at the lowest position and between the outer walls of the other two sides of the reinforcing beam 112 parallel to the second direction and the inner walls of the other two sides of the cavity 111 at the lowest position helps to make the reinforcing beam 112 and the front cabin side beam 11 into a complete whole, so that the whole strength is enhanced. In addition, the gap between the upper outer wall of the reinforcing beam 112 and the upper inner wall of the lowermost cavity 111 enables the reinforcing beam 112 to be conveniently penetrated in the front cabin side beam body 11 during assembly, so that difficult assembly is avoided.

The reinforcing beam 112 penetrates through the cavity 111, and two ends of the reinforcing beam 112 are flush with two ends of the cavity 111. The overall structural strength of the front cabin edge beam body 11 at the head and the tail can be ensured.
