[0037] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0038] Example 1

[0039] This embodiment provides a door sill beam for use in vehicles. It adopts a progressive deformation energy-absorbing structure with a weak outer layer and a strong inner layer to accelerate the absorption of impact forces from outside the vehicle. The details are explained below.

[0040] like Figures 1-3 As shown, the door sill beam includes a first cavity 11 and a second cavity 12 disposed adjacent to each other. The first cavity 11 is disposed near the interior of the vehicle, and the second cavity 12 is disposed near the exterior of the vehicle. The upper wall and / or lower wall of the first cavity 11 extends into the second cavity 12 along the Z-axis direction. The upper wall and / or lower wall of the first cavity 11 forms an acute angle with respect to the inner sidewall 23 of the first cavity 11.

[0041] In this embodiment, the lower wall of the first cavity 11 extends into the second cavity 12 along the Z-axis, and the lower wall of the first cavity 11 forms an acute angle with respect to the inner wall 23 of the first cavity 11.

[0042] In this embodiment, the straight-line driving direction of the vehicle is defined as the X-axis direction, the direction between the left and right sides of the vehicle is defined as the Y-axis direction, the direction between the roof and the floor of the vehicle is defined as the Z-axis direction, the forward driving direction of the vehicle is defined as the front of the vehicle, and the reverse driving direction of the vehicle is defined as the rear of the vehicle.

[0043] The first cavity 11 is sequentially connected and surrounded by the first upper wall 24, the connecting wall 21, the first lower wall 22 and the inner side wall 23; and the second cavity 12 is sequentially connected and surrounded by the second upper wall 25, the outer side wall 26, the second lower wall 27 and the connecting wall 21. The connecting wall 21 can be a split piece or an integral piece, and the embodiment is described by taking the connecting wall 21 as an integral piece.

[0044] The sill beam is divided into the first cavity 11 and the second cavity 12 by the connecting wall 21, the second cavity 12 is formed in a substantially rectangular structure, the first cavity 11 is formed in a substantially right trapezoidal structure, the short side of the pair of sides of the first cavity 11 is equal in length to one side of the second cavity 12, and it is understood that the second cavity 12 and the first cavity 11 are connected by the connecting wall 21, the connecting wall 21 is the short side of the pair of sides of the first cavity 11 and is also one side of the second cavity 12.

[0045] In the embodiment, the cross-sectional area of the second cavity 12 of the sill beam is smaller than the cross-sectional area of the first cavity 11, forming a progressive deformation energy absorption structure with outer weakness and inner strength, and the deformation energy absorption effect of the sill beam when subjected to lateral collision is better. Compared with the existing sill beam with equal strength design, the equal strength cavity structure that resists deformation makes it difficult to deform, and the side collision force is directly transmitted to the sill inner plate 31 and the bottom parts of the vehicle without deformation energy absorption, which causes the deformation of the sill inner plate 31 and other components to be large, and the internal power battery of the vehicle is not protected enough.

[0046] The connecting wall 21, the first lower wall 22, the inner side wall 23, the first upper wall 24, the second upper wall 25, the outer side wall 26 and the second lower wall 27 are sequentially connected to form an integral structure. The connecting wall 21 is arranged along the Z-axis direction.

[0047] The end of the connecting wall 21 away from the first lower wall 22 is provided with a first bending part 28, the first bending part 28 is connected with the second upper wall 25, and the first bending part 28 extends to the second upper wall 25 along the Y-axis direction to fix the upper end of the connecting wall 21; specifically, the first bending part 28 is arranged at the connection between the first upper wall 24 and the second upper wall 25, the first upper wall 24 is aligned with and integrally arranged with the second upper wall 25, and the first upper wall 24 and the second upper wall 25 are arranged along the Y-axis direction.

[0048] The connecting manner of the first bending part 28 and the second upper wall 25 can be welding, riveting or screwing, and in the embodiment, the first bending part 28 and the second upper wall 25 are fixed by welding.

[0049] The end of the second lower wall 27 away from the outer side wall 26 is provided with a second bending part 29, the second bending part 29 is connected with the connecting wall 21, and the second bending part 29 extends to the connecting wall 21 along the Z-axis direction to fix the lower end of the connecting wall 21.

[0050] The connection mode of the second bending part 29 and the connecting wall 21 can be welding, riveting or screwing, and in the embodiment, the second bending part 29 and the connecting wall 21 are fixed by welding.

[0051] In the embodiment, the rocker beam is made of high-strength steel by rolling process. First, the first bending part 28 is rolled, then the first bending part 28 is welded with the second upper wall 25, and then the second bending part 29 is rolled again until the second bending part 29 is rolled to the end, and the second bending part 29 is welded with the connecting wall 21 to form a self-sealing integrated double-cavity structure. The double-cavity structure has good cross-sectional stability and good load-bearing characteristics. The parts integrated into the rocker beam have high integration, and the efficiency of the rocker beam made by the rolling process is higher. Compared with the rocker beam made by the existing aluminum alloy extrusion process, the rocker beam has the advantage of reducing cost.

[0052] The second upper wall 25 and the second lower wall 27 are arranged in parallel and along the Y-axis direction; the connecting wall 21 and the outer side wall 26 are arranged in parallel and along the Z-axis direction. The outer side wall 26 is arranged close to the outside of the vehicle, and the inner side wall 23 is arranged close to the inside of the vehicle.

[0053] The lower end of the inner side wall 23 extends downward relative to the lower end of the connecting wall 21 along the Z-axis direction, the first lower wall 22 includes a connected inclined part 221 and a transition part 222, the end of the inclined part 221 is connected with the lower end of the inner side wall 23, and the end of the transition part 222 is connected with the lower end of the connecting wall 21. The inclined part 221 extends upwardly and obliquely from the inner side wall 23 to the connecting wall 21, and the acute angle between the inclined part 221 and the inner side wall 23 is in the range of 25°-70°. The transition part 222 is aligned with and separately arranged from the second lower wall 27, and the transition part 222 and the second lower wall 27 are arranged along the Y-axis direction. The inclined part 221 forms an inclined guide feature relative to the inner side wall 23, and the first cavity 11 has a larger energy absorption space by arranging the inclined part 221, which can better absorb energy and collapse. The inclined part 221 is connected with the transition part 222, and the transition part 222 is connected with the connecting wall 21. The transition part 222 is close to the position where the second bending part 29 and the connecting wall 21 meet, which further enhances the stability of the welding of the second bending part 29 and the connecting wall 21. At the same time, the force transmission path from the second lower wall 27 to the connecting wall 21 and the transition part 222 is coherent and efficient, which strengthens the energy absorption effect.

[0054] The inner sidewall 23 includes a reinforcing portion 231 and a sidewall body 232 connecting the two ends of the reinforcing portion 231. The reinforcing portion 231 protrudes towards the first cavity 11 relative to the sidewall body 232. The upper end of the sidewall body 232 is connected to the end of the first upper wall 24, and the lower wall of the sidewall body 232 is connected to the end of the inclined portion 221. The sidewall body 232 and the connecting wall 21 can be parallel, and the reinforcing portion 231 is located approximately in the middle of the inner sidewall 23. The inner sidewall 23, including the reinforcing portion 231, can further enhance the stiffness of the sill beam along the Z-axis direction, thereby improving the safety and reliability of the sill beam under a 25% offset collision condition.

[0055] The outer wall 26 and the inclined part 221 are respectively provided with welding through holes 13 to facilitate welding and fixing of the sill beam; the outer wall 26 and the inclined part 221 are respectively provided with weight reduction holes to facilitate lightweight management.

[0056] In this embodiment, the upper and / or lower walls of the first cavity 11 in the sill beam extend into a second cavity 12 along the Z-axis direction. The upper and / or lower walls of the first cavity 11 form an acute angle with respect to the inner wall 23 of the first cavity 11. When a collision force occurs, the force is guided to deform along the inclined direction of the upper and / or lower walls of the first cavity 11. The force transmission path of the entire sill beam is coherent and efficient, which can effectively disperse the collision force and reduce the impact force on the internal components of the vehicle, such as reducing the impact force on the passenger compartment and battery compartment.
