DETAILED DESCRIPTION

[0026] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0027] Please refer to Figure 1 The utility model discloses an anti-collision beam with multiple energy absorption channels, the anti-collision beam comprises an upper cross beam 100 and a lower cross beam 200 fixedly connected to each other, a first energy absorption box 111 is arranged on the upper cross beam 100, a second energy absorption box 210 is arranged on the lower cross beam 200, the upper cross beam 100 comprises a first beam body 110 and a second beam body 120 fixedly connected to each other, and a third energy absorption box 121 is also arranged on the first beam body 110 and / or the second beam body 120.

[0028] Specifically, the present application divides the upper cross beam 100 into a first beam body 110 and a second beam body 120, the first energy absorption box 111 is fixedly connected to the first beam body 110 and the second beam body 120 at the same time, the second energy absorption box 210 is fixedly connected to the lower cross beam 200, and a third energy absorption box 121 is added to the second beam body 120 and / or the first beam body 110, so that the entire front of the car has at least three energy absorption paths to improve the energy absorption effect of the entire vehicle during a collision.

[0029] At the same time, the upper cross beam 100 is fixedly connected to the lower cross beam 200, and the first beam body 110 is fixedly connected to the second beam body 120, so that the three energy absorption paths form an integral energy absorption structure. During energy absorption, the energy of the collision can be transferred between the three energy absorption paths, so that the three energy absorption paths can work together to further improve the energy absorption effect during a frontal collision of the vehicle.

[0030] Furthermore, the second beam body 120 is located on a side of the first beam body 110 close to the lower cross beam 200, and the second beam body 120 includes a main body fixedly connected to the first beam body 110, and both ends of the main body extend a bending portion in a direction toward the lower cross beam 200, and the bending portion is connected to the lower cross beam 200; the third energy absorption box 121 is arranged on the main body and / or the bending portion.

[0031] Specifically, the two ends of the second beam body 120 are bent downward and connected to the lower beam 200 to replace the solution of connecting through the connecting plate, thereby reducing the welding positions. When the third energy absorbing box 121 is arranged at the bent portion, the bent portion is stressed and transmits the force to the upper beam 100 and the lower beam 200 at the same time, so that the upper and lower beams 200 absorb energy at the same time, so as to enhance their energy absorption effect.

[0032] For further information, please refer to Figure 2 The second beam body 120 is located on a side of the first beam body 110 close to the lower cross beam 200 . The second beam body 120 includes a main body fixedly connected to the first beam body 110 . Both ends of the main body are bent toward the inner side of the vehicle body to form the third energy absorption box 121 .

[0033] The first beam body 110 and the second beam body 120 may be located above the lower beam 200 , and the second beam body 120 may be located below the first beam body 110 , or the first beam body 110 and the second beam body 120 may be located at the same height.

[0034] Furthermore, the first beam body 110 and the second beam body 120 are integrally formed.

[0035] Please refer to Figure 3 The present application also discloses a front cabin collision system, including the anti-collision beam with multiple energy absorption channels.

[0036] One end of the first energy absorbing box 111 away from the upper cross beam 100 is fixedly connected to a longitudinal beam 112 of the vehicle. The upper cross beam 100 , the first energy absorbing box 111 and the longitudinal beam 112 form a first energy absorbing path.

[0037] Specifically, the first energy absorption box 111 is arranged on the upper cross beam 100 and is fixedly connected to the longitudinal beam 112 of the automobile, so that when a collision occurs at the front of the automobile, the energy is transferred from the upper cross beam 100 to the first energy absorption box 111, and then from the first energy absorption box 111 to the longitudinal beam 112, so that the entire energy absorption structure and the longitudinal beam 112 on the automobile form an integral energy absorption path (i.e., the first energy absorption path), thereby improving its energy absorption effect.

[0038] Furthermore, one end of the second energy absorbing box 210 away from the lower cross beam 200 is fixedly connected to the sub-frame 220 , and the lower cross beam 200 , the second energy absorbing box 210 and the sub-frame 220 form a second energy absorbing path.

[0039] Specifically, the second energy absorbing box 210 is disposed on the lower cross beam 200 and is fixedly connected to the sub-frame 220 of the automobile, so that when a collision occurs at the front of the automobile, the energy is transferred from the lower cross beam 200 to the second energy absorbing box 210, and then from the second energy absorbing box 210 to the sub-frame 220, so that the entire energy absorbing structure and the sub-frame 220 on the automobile form an integral energy absorbing path (i.e., the second energy absorbing path), thereby improving its energy absorbing effect.

[0040] Furthermore, the third energy absorption box 121 is fixedly connected to the second beam body 120, one end of the third energy absorption box 121 away from the second beam body 120 is fixedly connected to the A-pillar extension beam 122, one end of the A-pillar extension beam 122 away from the third energy absorption box 121 is connected to the A-pillar of the automobile, and the second beam body 120, the third energy absorption box 121, the A-pillar extension beam 122 and the A-pillar of the automobile form a third energy absorption path.

[0041] Specifically, the third energy absorption box 121 is arranged on the second beam body 120 and fixedly connected to the A-pillar extension beam 122 of the automobile, and the A-pillar extension beam 122 is connected to the A-pillar of the automobile, so that when a collision occurs in the front of the automobile, the energy is transmitted from the second beam body 120 to the third energy absorption box 121, and then transmitted from the third energy absorption box 121 to the A-pillar extension beam 122 and the A-pillar of the automobile, so that the entire energy absorption structure and the A-pillar extension beam 122 on the automobile and the A-pillar of the automobile form an integral energy absorption path (i.e., the third energy absorption path), thereby improving its energy absorption effect.

[0042] It should be noted that when the first energy absorption path, the second energy absorption path and the third energy absorption path are absorbing energy, the energy absorption box first collapses and deforms to absorb the energy of the collision. If the collision force is relatively light, the energy of the collision can be completely absorbed by the energy absorption box, and the upper and lower cross beams 200 and the vehicle body structure will not be deformed, thereby also playing a protective role for the vehicle body structure.

[0043] Furthermore, one first energy absorbing box 111 is respectively disposed at both ends of the upper cross beam 100 , and the two first energy absorbing boxes 111 are symmetrical about the middle of the upper cross beam 100 ;

[0044] A second energy absorbing box 210 is respectively disposed at both ends of the lower cross beam 200 , and the two second energy absorbing boxes 210 are symmetrical about the middle portion of the lower cross beam 200 ;

[0045] One third energy absorbing box 121 is disposed at each end of the second beam body 120 , and the two third energy absorbing boxes 121 are symmetrical about the middle of the second beam body 120 .

[0046] Specifically, energy absorption boxes are respectively arranged at both ends of the upper cross beam 100 / lower cross beam 200 / second beam body 120, and the two energy absorption boxes are symmetrical about the middle of the upper cross beam 100 / lower cross beam 200 / second beam body 120, so that the energy absorption effect on the left and right sides of the front of the car is more uniform, thereby being able to cope with collisions at various angles.

[0047] The application also discloses a vehicle, comprising the front cabin collision system.
