The invention provides a passenger car with a battery compartment bottom collision protection structure, which comprises a frame, a battery compartment is arranged on the frame, the collision protection structure is mounted at the bottom of the battery compartment, the collision protection structure comprises a bottom protection structure fixed on the frame, and the bottom protection structure comprises a bottom protection plate. The collision protection structure further comprises a reinforcing protection structure located above the bottom protection structure, the reinforcing protection structure comprises a plurality of reinforcing beam bodies which are arranged at intervals, the ends of the reinforcing beam bodies are fixed to the frame, and a containing space allowing the corresponding part of the bottom protection plate to deform upwards is formed between every two adjacent reinforcing beam bodies. The collision protection structure at the bottom of the battery compartment of the passenger car can enter the corresponding accommodating space when being stressed and deformed, so that the compartment bottom of the battery compartment cannot be extruded; the technical problem that in the prior art, when a battery compartment bottom protection structure deforms under stress, a battery compartment deforms, and accordingly a battery is damaged is effectively solved.

    本发明提供一种具有电池舱底部碰撞防护结构的客车,该客车包括车架,车架上设有电池舱,电池舱的底部安装有碰撞防护结构,碰撞防护结构包括固定在车架上的底部防护结构,底部防护结构包括底部防护板,碰撞防护结构还包括位于底部防护结构上方的加强防护结构,加强防护结构包括间隔排布的多个加强梁体,加强梁体的端部固定在车架上,相邻的加强梁体之间形成供底部防护板相应部分向上变形的容纳空间。本发明提供的客车的电池舱底部碰撞防护结构在受力变形时会进入到相应的容纳空间中,因此不会对电池舱的舱底造成挤压,有效解决了现有技术中的电池舱底部防护结构在受力变形的同时会引起电池舱发生变形从而导致电池受损的技术问题。
