Embodiment 1

[0036] Such as figure 1 Shown and combined figure 2 To illustrate, the embodiment of the present invention provides a pedestrian lower limb protection device, which includes a mounting bracket 1 and a protection bracket 2;

[0037] The mounting bracket 1 is fixed on the front beam 3 of the car, and the mounting bracket 1 is located on the left and / or right side of the longitudinal centerline s of the car. The mounting bracket 1 includes a lower mounting surface 11, a rear mounting surface 12 and an upper mounting surface 13. The lower mounting surface 11, the rear mounting surface 12, and the upper mounting surface 13 form a U-shaped structure, and the mounting bracket 1 is covered by the rear side of the front crossbeam 3 on the front crossbeam 3 through the U-shaped structure, and the lower mounting surface 11 and The lower end surface 34 of the front protection beam is fixedly connected, the rear mounting surface 12 is fixedly connected to the rear end surface 33 of the front ...

Embodiment 2

[0054] See figure 2 And combine image 3 with Figure 4 To illustrate, an embodiment of the present invention provides an automobile including a front beam 3 and an upper grille. The automobile also includes the pedestrian lower limb protection device described in Embodiment 1, wherein the structure diagram of the pedestrian lower limb protection device is as follows: figure 1 As shown, the pedestrian lower limb protection device is fixed on the front protection beam 3 and located behind the upper grille.

[0055] Among them, the pedestrian lower limb protection device is installed on the front protection beam 3, and the U-shaped structure formed by the lower installation surface 11, the rear installation surface 12 and the upper installation surface 13 of the mounting bracket 1 is sleeved behind the front protection beam 3 The upper and lower mounting surface 11, the rear mounting surface 12 and the upper mounting surface 13 of the front protection beam 3 are respectively fixedly...

Abstract

The invention discloses a pedestrian's lower limb protection device and an automobile, belonging to the field of automobiles. The pedestrian lower body protection device includes a mounting bracket and a protection bracket. The present invention is fixed on the front crossbeam of the automobile through the installation bracket, and the protection bracket is fixed on the upper installation surface of the installation bracket, and prevents a large relative speed between the pedestrian's femur and tibia through the protection bracket, thereby reducing the tibia around the femur. The resilience generated by the rebound after rotation can avoid tibial fractures and reduce the injury of pedestrians’ lower limbs, and the installation bracket is located on the left and / or right side of the longitudinal centerline of the car, so that the protective bracket is impacted. The reaction force to the left or right side of the car, through which the pedestrian's lower limbs are turned to the left or right side of the car, because this rotation will not cause damage to the pedestrian's lower limbs, and the setting of the protective bracket reduces the impact of the pedestrian's lower limbs. The impact force received along the forward direction of the car can further reduce the injury to the pedestrian's lower limbs.

Description

Technical field [0001] The invention relates to the field of automobiles, in particular to a pedestrian lower limb protection device and an automobile. Background technique [0002] In recent years, how to protect pedestrians in traffic accidents and reduce the injuries to pedestrians caused by collisions between cars and pedestrians has become an important issue in car design. [0003] When the front of the vehicle hits the lower extremity of the pedestrian, the pedestrian’s tibia is in contact with the bumper skin of the car, and the femur is in contact with the upper grille. Because the front beam behind the bumper skin is rigid, the speed of the tibia can be The upper grille has a much lower stiffness than the front beam. After the pedestrian’s femur hits the upper grille, it may crush the upper grille and continue to move forward, resulting in a relative speed between the tibia and the femur. To protect the limit of the beam, the tibia cannot move forward, but rotates around ...
