[0024] The following are specific embodiments of the present utility model in combination with the drawings, and the technical solutions of the present utility model are further described, but the present utility model is not limited to these embodiments.
[0025] Please refer to Figure 1-Figure 2The utility model discloses an anti-collision beam, including an upper cross beam 100 and a lower cross beam 200, the upper cross beam 100 includes a first beam body 110 and a second beam body 120, the first beam body 110 is located on a side of the second beam body 120 close to the lower cross beam 200, the first beam body 110 includes a first main body 111, and two bending portions 112 respectively located at both ends of the first main body 111, the bending portion 112 is bent from the main body toward the lower cross beam 200 and fixedly connected to the lower cross beam 200.
[0026] Specifically, the present application divides the upper beam 100 into a first beam body 110 and a second beam body 120. Both ends of the first beam body 110 are bent toward the lower beam 200 to form a bent portion 112, and the bent portion 112 is connected to the lower beam 200 to replace the original solution of connecting the upper and lower beams 200 through a connecting plate. In this way, the number of connection points between the upper and lower beams 200 (welding or other connection methods) is reduced, thereby reducing assembly costs and the risk of breakage at the connection during impact.
[0027] Furthermore, the first beam body 110 is located on a side of the second beam body 120 close to the lower cross beam 200 , or the first beam body 110 and the second beam body 120 are at the same height; the first beam body 110 and the second beam body 120 are integrally formed.
[0028] The first beam body 110 and the second beam body 120 are integrally formed to avoid welding points between the first beam body 110 and the second beam body 120, so as to enhance the strength between the first beam body 110 and the second beam body 120 and improve the energy absorption effect.
[0029] Furthermore, the first beam body 110 has a first bottom surface facing the second beam body 120 , and the second beam body 120 has a second bottom surface facing the first beam body 110 , and a cutting space is defined between the first bottom surface and the second bottom surface.
[0030] The second beam body 120 includes a second body 121 and two extension portions 122 respectively located at two ends of the second body 121, and the second body 121 is fixedly connected to the first body 111;
[0031] Both ends of the upper cross beam 100 have a cutting section, and the cutting section can be divided along the cutting space to separate the bending portion 112 and the extending portion 122 .
[0032] Specifically, there is a cutting space between the first beam body 110 and the second beam body 120. Cut both ends of the upper cross beam 100 along the cutting space for a certain length to separate the bending part 112 on the first beam body 110 and the extending part 122 on the second beam body 120. Then bend the bending part 112 towards the lower cross beam 200, and finally connect the bending part 112 to the lower cross beam 200, thus realizing the connection of the upper and lower cross beams 200 to replace the original connection scheme using a connecting plate.
[0033] Further, the bending part 112 further includes two first side surfaces respectively fixed at both ends of the first bottom surface, and the first side surfaces protrude from the first bottom surface.
[0034] The extending part 122 further includes two second side surfaces respectively fixed at both ends of the second bottom surface, and the second side surfaces protrude from the second bottom surface.
[0035] The cross sections of the bending part 112 and the extending part 122 are both quadrilateral.
[0036] The first body 111 and the second body 121 are fixedly connected to form a fixed connection section, and the two cutting sections are respectively located at both ends of the fixed connection section. The cross section of the fixed connection section is in the shape of a Chinese character "mu" (eye).
[0037] Specifically, the cross sections of the first beam body 110 and the second beam body 120 are both in the shape of a square with a hollow center. There is a cutting space between the first beam body 110 and the second beam body 120, such that the cross section of the fixed connection section formed by the first body 111 and the second body 121 is in the shape of a Chinese character "mu" (eye). Of course, the cross section shape of the fixed connection section depends on the shapes of the first beam body 110 and the second beam body 120. The cross section shapes of the first beam body 110 and the second beam body 120 can be set to other shapes, and the cross section shape of the fixed connection section will change accordingly.
[0038] Define the connection section of the first body 111 and the second body 121 as the fixed connection section, and the cross section of this fixed connection section is in the shape of a Chinese character "mu" (eye).
[0039] Further, the bending part 112 includes a bending section and a vertical section, and both ends of the bending section are respectively connected to the first body 111 and the vertical section.
[0040] Further, the bending section bends gradually towards the lower cross beam 200 along the direction from the first body 111 towards the bending section.
