The development of electrification is widely considered to be the key to the transportation industry. In recent years, the number of electric trucks on the road is increasing year by year, so the safety of electric trucks is of great importance. At present, the batteries of electric trucks are mostly arranged on the two sides of the trucks. The protective devices are only the guardrails fixed on the vehicle body, so the protective effect is poor. In view of this situation, this paper designed a battery protection device for electric truck. When the truck is hit in a side collision, the transverse guardrail first generates plastic deformation and absorbs kinetic energy. At this time, the collision force is transmitted to the energy-absorbing box along the moving direction of the side collision vehicle, and the energy-absorbing box is contracted to produce a buffer effect. When the guardrail and the energy-absorbing box are deformed, the slider connected above the guardrail slides along the guide rail to play a guiding role to ensure the normal operation of the mechanism. By this way it can reduce the collision force received by the battery to achieve the protection of the truck battery.
This paper carries out the side collision simulation of electric trucks, analyzing the speed, displacement, energy of some points on the guardrail during the collision、speed and acceleration of the collision vehicle to verify the effectiveness of the battery protection device. This study has a supplementary role in the safety research of electric vehicles.
