Problems solved by technology
For a pure plastic support structure, it is easy to break the plastic during the collision with pedestrians, so that it cannot effectively protect pedestrians; for metal brackets and metal pipe beam structures, if the metal bracket is not strong enough , in the process of colliding with pedestrians, more serious plastic deformation is prone to occur, the bending deformation of the pedestrian's leg is serious, and the ligament is pulled up a lot, and if the strength of the metal bracket is too strong, it is easy to cause the leg of the pedestrian to fracture. Can't effectively protect the legs

Embodiment Construction
[0028] The present invention will be described in detail below in conjunction with the accompanying drawings.
[0029] Such as Figure 1-Figure 10 As shown, a pedestrian leg protection structure in this embodiment includes a front bumper 10, a support element 20 and a cushioning pushback elastic element 30, and the front bumper 10 and the support element 20 are respectively connected to the vehicle body connected, the buffering anti-thrust elastic element 30 is connected to the front of the support element 20 and the buffering anti-thrust elastic element 30 protrudes forward from the support element 20, and the buffering anti-thrust elastic element 30 is located at the The rear side of the lower part of the front bumper 10; the support element 20 is made of plastic material, and the cushioning and anti-thrust elastic element 30 is made of rubber. Specifically, the support element 20 is made of PP+EPDM material, which has high strength and toughness, and the cushioning and anti...

The invention discloses a pedestrian leg protection structure which comprises a front bumper, a supporting element and a buffering reverse thrust elastic element, and the front bumper and the supporting element are connected with an automobile body. The buffering reverse-pushing elastic element is connected with the front portion of the supporting element, the buffering reverse-pushing elastic element forwards extends out of the supporting element, and the buffering reverse-pushing elastic element is located on the rear side of the lower portion of the front bumper. According to the pedestrian leg protection structure, the legs of a collided pedestrian can be protected, the bending deformation degree of the legs of the collided pedestrian is reduced, the ligament lifting amount is reduced, and therefore damage to the legs of the collided pedestrian is reduced.
Description
technical field [0001] The invention relates to the technical field of automobile parts, in particular to a pedestrian leg protection structure. Background technique [0002] In the past decade or so, the protection of pedestrians outside the vehicle has been valued by various automobile companies and related countries in the world. The introduction of relevant laws and regulations on pedestrian protection and the formal inclusion of pedestrian protection in the new car evaluation regulations all show that the safety of pedestrians outside the vehicle is becoming more and more important. Pay attention to. At present, for the protection structure of pedestrian legs, the main structural forms are plastic material support, metal support or metal pipe beam support located on the rear side of the front bumper. For a pure plastic support structure, it is easy to break the plastic during the collision with pedestrians, so that it cannot effectively protect pedestrians; for metal b...
