[0044] Such as Figure 1 to Figure 6 As shown, the energy-absorbing footrest provided by the first aspect of the present invention includes a first footrest 2 and a second footrest 7, the first footrest 2 includes a first conne...

Embodiment 2

[0057] In order to facilitate movement, in any of the above technical solutions, further, the shape of the top of the friction crack 9 is consistent with the shape of the bottom of the interference friction block 5 . The bottom of the interference friction block 5 is V-shaped, which is convenient for the interference friction block 5 to move downward along the friction crack 9 .

[0058] In the energy-absorbing footrest provided by the present invention, under the frontal collision of the second footrest 7, the second footrest 7 is subjected to the impact transmitted by the front wall of the vehicle, and the upper part of the first footrest 2 is stepped on by the left foot of the driver. The first footrest 2 moves downward, increasing the space between the feet and the first footrest 2 .

[0059] Analysis of the principle of cowl intrusion on the lower leg of the dummy during a frontal high-speed collision shows that there is a footrest between the cowl and the dummy's feet, a...

Abstract

The invention provides an energy-absorption foot rest and a vehicle and relates to the technical field of vehicle safety. The energy-absorption foot rest comprises a first foot rest body and a secondfoot rest body and is characterized in that the first foot rest body comprises a first connector, the second foot rest body comprises a second connector, a collapse energy absorption mechanism is arranged on each of the first connector and the second connector, and the first connector can be movably arranged in the second connector. The energy-absorption foot rest has the advantages that the collapse energy absorption mechanism is arranged on each of the first connector and the second connector, so that the first connector can be movably arranged in the second connector; when head-on high-speed collision occurs, impact from the front wall of the vehicle is transmitted to the second foot rest body, the upper part of the first foot rest body is treaded by the left foot of a driver, the firstfoot rest body moves downwardly at the very moment, the space between the foot and the first foot rest body is increased, impact on the feet of the driver is lowered, and damage to the shanks of thedriver is reduced greatly.

Description

technical field [0001] The invention relates to the technical field of vehicle safety, in particular to an energy-absorbing footrest and a vehicle. Background technique [0002] At present, hard plastic blocks or foam blocks are used on models. Hard plastic blocks can play a supporting role, but they do not have the function of collapse and energy absorption. Although foam blocks can absorb energy, the energy absorption effect is relatively small. The calf protection effect is not good, which will bring several problems: [0003] If the footrest on the driver's left foot is a hard plastic block, although it can support the sole of the foot, the hard plastic block will not absorb energy and collapse during a frontal collision, and all the energy will be transferred to the driver's left foot and left calf , causing direct damage to the driver's left calf. [0004] If the driver's left footrest is a foam block, it can play the role of sole support, and it can also play a cert...
