[0049] Some embodiments will be described below with reference to the accompanying drawings. The following embodiments and features in the embodiments can be combined with each other without conflict.
[0050] Please refer to Figure 1 A conventional leg support structure often includes a front bumper upper mounting bracket 501 (generally the same component as the support bracket of the through light 502), a bumper beam buffer foam 503, a calf bracket 504, etc. The design in the transverse direction of the middle of the vehicle is generally uniform. However, the outer side of the front end module is affected by the change of the front end modeling curved surface, and some areas may retreat more, resulting in that the leg injury value in this area is large due to insufficient buffer space, especially the thigh and hip area. Because of the influence of the upper body trunk mass, the kinetic energy borne during the collision is much larger than that of the calf area. Relying solely on the existing front bumper upper mounting bracket cannot balance the modeling requirements and the leg protection performance in the collision.
[0051] In view of this, the embodiments of the present application provide a front end crush energy absorption structure and a vehicle to realize step-by-step energy absorption deformation and crush of external force impact and improve the safety performance of the vehicle.
[0052] Please refer to Figure 7 The embodiments of the present application provide a front end crush energy absorption structure 100 applied to a vehicle 200. In some embodiments, the vehicle 200 can be a sedan, a sport utility vehicle (SUV), a van, a motor home, etc. Please refer to Figure 2 and Figure 7 The vehicle 200 can include a hood 1, a through light 2, a front bumper 3, a front end module 4, and a front end crush energy absorption structure 100.
[0053] Please refer to Figures 2 to 5 The hood 1, the through light 2, and the front bumper 3 are sequentially arranged adjacent to each other in the vertical direction from top to bottom at the front end of the vehicle and are the appearance structure of the vehicle. In some embodiments, the hood 1, the through light 2, and the front bumper 3 are the front end of the vehicle. When the vehicle touches or collides with an external object, such as a pedestrian's leg, the position of the front bumper 3 generally corresponds to the leg of an average adult pedestrian, which is the force area affected by the external force impact.
[0054] Please refer to Figure 2 and Figure 7, the front end module 4 is disposed horizontally adjacent to the front bumper 3, and the front end module 4 is an internal structure of the vehicle. The front end crush energy absorption structure 100 is connected to the front bumper 3 and the front end module 4 respectively, and is an internal structure of the vehicle. In some embodiments, the front bumper 3 is substantially arc-shaped, extending from the front end of the vehicle to both sides, and the front end module 4 substantially corresponds to the middle position of the front bumper 3.
[0055] Please refer to Figure 6 , Figure 7 , Figure 23 and Figure 24 , the front end crush energy absorption structure 100 can include a right top rod 5, a right crush bracket 6, a left crush bracket 7 and a left top rod 8.
[0056] The right top rod 5 and the left top rod 8 are connected to the front bumper 3 respectively.

In some embodiments, the right top rod 5 and the left top rod 8 have the same structure and are symmetrically arranged.
[0057] The right crush bracket 6 and the left crush bracket 7 are connected to the front end module 4 respectively. In some embodiments, the right crush bracket 6 and the left crush bracket 7 are symmetrically connected to the left and right sides of the front end module 4 respectively. The right crush bracket 6 is arranged corresponding to the right top rod 5, and the left crush bracket 7 is arranged corresponding to the left top rod 8. In some embodiments, the right crush bracket 6 and the left crush bracket 7 have the same structure and are symmetrically arranged.
[0058] Please refer to Figures 18 to 22 , each of the right crush bracket 6 and the left crush bracket 7 includes a front crush piece 61 and a rear crush piece 62. In some embodiments, the front crush piece 61 and the rear crush piece 62 are arranged in front and back along the normal direction of the front bumper 3, and the front crush piece 61 and the rear crush piece 62 are used to absorb external force and break when crushed.
[0059] When the right top rod 5 corresponding to the front bumper 3 touches or collides with an external object and is impacted by an external force, for example, collides with a pedestrian's leg, the right top rod 5 hits the front crush piece 61 of the right crush bracket 6, causing the front crush piece 61 to crush and break to absorb the energy of the external force impact, thereby forming a first energy absorption deformation crush. The right top rod 5 then hits the rear crush piece 62 of the right crush bracket 6, causing the rear crush piece 62 to crush and break to further absorb the energy of the external force impact, thereby forming a second energy absorption deformation crush.
[0060] When the left top rod 8 corresponding to the front bumper 3 touches or collides with an external object and is impacted by an external force, for example, collides with a pedestrian's leg, the left top rod 8 impacts the front crush member 61 of the left crush bracket 7, causing the front crush member 61 to crush and break to absorb the energy of the external force impact, thereby forming a first energy-absorbing deformation crush. The left top rod 8 then impacts the rear crush member 62 of the left crush bracket 7, causing the rear crush member 62 to crush and break to further absorb the energy of the external force impact, thereby forming a second energy-absorbing deformation crush. Therefore, the front-end crush energy-absorbing structure 100 realizes step-by-step energy-absorbing deformation crush, reduces the damage to the pedestrian's leg in the vehicle front-end area, improves the pedestrian collision protection performance of the vehicle, and better protects the safety of pedestrians. In addition, the front-end crush energy-absorbing structure 100 of the embodiment of the application has simple structure design, light mass, convenient installation, and high reliability.

[0063] The plurality of welding portions 521 are distributed at a plurality of positions of the base plate 520, and the plurality of welding portions 521 are used to be connected to the front bumper 3 by hot melt welding, so as to fix the right top rod 5 and the left top rod 8 on the front bumper 3. The top support rod 510 protrudes in the opposite direction of the plurality of welding portions 521. The top support rod 510 includes a plurality of cross rib portions 512 and a support base 514. The support base 514 is arranged to protrude from the base plate 520, and the plurality of cross rib portions 512 are arranged to protrude from the support base 514. In some embodiments, the support base 514 and the plurality of cross rib portions 512 are arranged to protrude in the normal direction of the front bumper 3. The plurality of cross rib portions 512 are arranged corresponding to the front crush member 61 and the rear crush member 62, and are used to impact the front crush member 61 and / or the rear crush member 62 when impacted by an external force.
[0064] A plurality of top rod reinforcing ribs 531 are symmetrically arranged on opposite sides of the support base 514, for increasing the structural strength of the support base 514 and the plurality of cross rib portions 512. In some embodiments, the right top rod 5 and the left top rod 8 can be made of, but are not limited to, PP-EPDM-TD20 material, which can take into account the support strength and the shrinkability and deformation performance of the front bumper 3.
[0065] Please refer to Figures 18 to 22 The front crush member 61 includes a front blocking piece 611 and a front tearing piece 612. The front blocking piece 611 is connected with the front tearing piece 612, and the front blocking piece 611 is arranged corresponding to the plurality of cross rib portions 512 of the right top rod 5 or the left top rod 8. In some embodiments, the width and thickness of the front tearing piece 612 are smaller than those of the front blocking piece 611. When the front bumper 3 is impacted by external force, the top support rod 510 of the right top rod 5 or the left top rod 8 hits the corresponding front blocking piece 611, and the front tearing piece 612 is crushed and broken, thereby absorbing the energy of the external force impact by crushing the structure of the front crush member 61.
[0066] The rear crush member 62 includes a rear blocking piece 621 and a rear tearing piece 622. The rear blocking piece 621 is connected with the rear tearing piece 622, the rear blocking piece 621 is arranged corresponding to the front blocking piece 611, and the rear tearing piece 622 is arranged corresponding to the front tearing piece 612.

In some embodiments, the normal direction of the front blocking piece 611, the front tearing piece 612, the rear blocking piece 621 and the rear tearing piece 622 is consistent with the direction of the top support rod 510, thereby ensuring that the top support rod 510 can hit the front blocking piece 611 and the rear blocking piece 621.
[0067] Each of the right crush bracket 6 and the left crush bracket 7 further includes a plurality of upper reinforcing ribs 631 and a plurality of lower reinforcing ribs 632.

Thus, the front end crush energy-absorbing structure 100 can realize step-by-step energy-absorbing deformation crush, reduce the damage of the front end region of the vehicle to the pedestrian's leg, improve the pedestrian collision protection performance of the vehicle, and better protect the safety of pedestrians.
