Fig. 1 is a sectional view of the vehicle rocker beam of the embodiment. As shown in fig. 1, the vehicle rocker beam includes a rocker outer panel 1, a rocker inner panel 2, a first reinforcement 3, and a second reinforcement 4. The threshold outer plate 1 and the threshold inner plate 2 are transversely arranged opposite to each other to surround to form an accommodating cavity 6. First reinforcement 3 and second reinforcement 4 set up in holding chamber 6, can increase threshold planking 1 and threshold inner panel 2's structural strength and anti bending property, have reduced the deformation volume that produces to the vehicle inside when the side impact takes place, can reduce the extrusion injury of automobile body to the battery from this to reduce the risk that the battery takes place to catch fire.

Specifically, the first reinforcement 3 is located in the accommodating cavity 6, and the first reinforcement 3 is connected to the rocker outer panel 1. When the threshold outer plate 1 is subjected to a transverse external force, the threshold outer plate 1 deforms, and the first reinforcing part 3 is driven to move towards the direction of the threshold inner plate 2. The first reinforcing member 3 can absorb collision energy, reduce the amount of deformation and collision energy transmitted to the battery 5, reduce the squeezing action on the battery 5, and have the effect of effectively protecting the battery 5. Furthermore, the first reinforcement 3 is spaced from the threshold inner plate 2, so that the first reinforcement 3 can be prevented from directly contacting and colliding the threshold inner plate 2 and the battery 5 when the threshold outer plate 1 collides, the battery 5 can be further protected, and the safety performance of the battery 5 is further improved. The second reinforcement 4 is located in the accommodating cavity 6, and the second reinforcement 4 is connected with the inner sill panel 2. The second reinforcement 4 can increase the structural strength and bending resistance of the whole of the rocker inner panel 2 and the rocker outer panel 1. Meanwhile, the rocker inner panel 2 is also connected to an external battery 5. In the present application, the battery 5 and the second reinforcement 4 are connected to the rocker inner panel 2 at the same position. That is, the battery 5 and the second reinforcement 4 are connected to the same connection face of the rocker inner panel 2. Preferably, the battery 5 and the second reinforcement 4 are connected to the bottom surface of the rocker inner panel 2.

Specifically, the first reinforcement 3 includes a first inclined surface 31 extending obliquely upward from one end close to the rocker outer panel 1 toward the rocker inner panel 2, and a first horizontal surface 32 extending horizontally from one end close to the rocker inner panel 2 of the first inclined surface 31 toward the rocker inner panel 2, as shown in fig. 1. The second reinforcement 4 includes a second inclined surface 41 that extends obliquely upward from an end close to the rocker outer panel 1 toward the rocker inner panel 2, and a second horizontal surface 42 that extends horizontally from an end close to the rocker inner panel 2 of the second inclined surface 41 toward the rocker inner panel 2, as shown in fig. 1. The first horizontal surface 32 is located above the second horizontal surface 42, and the first inclined surface 31 and the second inclined surface 41 are parallel to each other and are disposed to face each other in the horizontal direction.

When the rocker outer panel 1 is deformed by a lateral impact force, the rocker outer panel 1 and the first reinforcement 3 move toward the inside of the vehicle, the first reinforcement 3 gradually comes into contact with the second reinforcement 4, and the first inclined surface 31 comes into contact with the second inclined surface 41, as shown by the broken line in fig. 2. Because the contact surface formed by the first inclined surface 31 and the second inclined surface 41 forms an included angle with the ground, under the guiding action of the contact surface, a part of the impact force can be turned to the direction parallel to the contact surface and upward, so that the first reinforcing part 3 is gradually lifted; another part of the impact force is deflected in the direction of the attachment surface of the second reinforcement 4 (i.e., the battery 5) to the rocker inner panel 2. When the deformation continues to occur, since the second reinforcement 4 and the battery 5 are connected to the rocker inner panel 2 at the same position, the second reinforcement 4 is pressed toward the ground, and the battery 5 is also deflected toward the ground. The mode of above-mentioned converting the horizontal impact force into two kinds of component forces can reduce the invasion volume of 5 horizontal directions of battery, can also remove the battery to the vehicle bottom direction simultaneously, avoids battery and body structure to take place direct contact to play the effect of protection battery.

Preferably, the included angle between the first inclined surface 31 and the second inclined surface 41 and the horizontal direction is 15-25 °, so that the impact force can be smoothly guided to the mounting point of the battery to be deformed, more impact force is converted into component force towards the ground direction, the component force of the battery 5 in the horizontal direction is reduced to the maximum extent, and the battery can be further protected.

When the threshold outer panel 1 is deformed by the transverse impact force, the first reinforcing member 3 is gradually contacted with the second reinforcing member 4, the first horizontal surface 32 is contacted with the second horizontal surface 42, the horizontal guiding effect can be achieved, the transverse deformation movement of the first reinforcing member 3 is guided, the first inclined surface 31 can be smoothly contacted with the second inclined surface 41, and the shunting effect is achieved.

Preferably, buffer distances are respectively arranged between the first reinforcing member 3 and the rocker inner panel 2, between the first inclined surface 31 and the second inclined surface 41, and between the first horizontal surface 32 and the second horizontal surface 42, so that an appropriate buffer distance can be provided for the first reinforcing member 3 and the rocker outer panel 1, the battery deflection caused by the direct contact of the first reinforcing member 3 and the second reinforcing member 4 under the action of small impact force can be avoided, and the battery protection effect can be further achieved.

The first reinforcing part 3 and the second reinforcing part 4 are hollow aluminum profile extrusion parts. That is, the first reinforcing member 3 and the second reinforcing member 4 are formed by extruding an aluminum profile to have a structure with hollows inside. The density of aluminium alloy extruded article is less, has certain anti collision strength, and the lightweight and the anti collision performance of vehicle threshold roof beam can be guaranteed to the aluminium alloy extruded article of fretwork form to guarantee the lightweight and the anti collision performance of vehicle. The hollow-out reinforcing piece can absorb energy generated by collision by adjusting the size of the hole, namely adjusting the sectional size and the shape of the reinforcing piece, and can adjust the proportion of absorbing collision energy according to specific deformation proportion and size.

Further, the first reinforcement 3 and the second reinforcement 4 extend in the longitudinal direction of the rocker outer panel 1 and the rocker inner panel 2, so that the projection of the first reinforcement 3 and the second reinforcement 4 on the battery 5 can completely cover the battery 5.
