The invention discloses an auxiliary frame, a vehicle and a battery pack anti-collision control method of the vehicle. The auxiliary frame comprises an auxiliary frame body and a protection assembly, the protection assembly has a preparation state and an excitation state, the protection assembly comprises a protection beam, a telescopic rod set and an elastic connecting piece, the protection beam is arranged below the auxiliary frame body, and the telescopic rod set is connected between the protection beam and the auxiliary frame body; the elastic connecting piece is connected between the protective beam and the auxiliary frame body. According to the auxiliary frame provided by the embodiment of the invention, the ground clearance of the protection assembly in the preparation state is large so as to ensure the trafficability of the vehicle, when the vehicle has the risk of bottom scraping, the protection assembly can be switched to the excitation state, the ground clearance of the protection assembly is reduced, and the protection assembly can protect the battery pack behind the protection assembly; therefore, the battery pack is prevented from being collided or scraped by a ground bulge, the risk of damage and even explosion of the battery pack is reduced, the maintenance cost of the vehicle is reduced, and the safety of the vehicle is improved.

    本发明公开了一种副车架、车辆和车辆的电池包防撞控制方法。该副车架包括副车架本体和防护组件,防护组件具有准备状态和激发状态,防护组件包括:防护梁、伸缩杆组和弹性连接件,防护梁设于副车架本体的下方,伸缩杆组连接于防护梁和副车架本体之间,弹性连接件连接于防护梁和副车架本体之间。根据本发明实施例的副车架,其防护组件在准备状态下的离地间隙较大,以保证车辆的通过性,当车辆具有刮底风险时,防护组件可切换为激发状态,防护组件的离地间隙变小,防护组件可对其后方的电池包进行防护,以阻挡地面凸出物撞击或刮擦电池包,降低电池包损伤甚至爆炸的风险,从而有利于降低车辆的维修费用,提升车辆的安全性。
