The invention provides a hydraulic control system, a battery box protection system and a wide-body vehicle. The hydraulic execution element is used for driving the protective cover of the vehicle to move, and the reversing valve is used for achieving movement reversing of the protective cover, so that the protective cover can open or close the battery replacement channel, and when the battery replacement channel is closed, the battery box can be protected at the battery replacement channel; external stones are prevented from moving to collide with the battery box through the battery replacement channel; moreover, an energy accumulator is arranged on an oil supply path of the reversing valve, and hydraulic oil can be supplied through the energy accumulator under special conditions such as no hydraulic pressure of a hydraulic source, so that a hydraulic execution element can still act or keep an action state, and the cruising ability of the hydraulic control system is improved; and the energy accumulator can stabilize the pressure of an oil supply way, the situation that due to the fact that the fluctuation of the pressure difference between working oil ports of the reversing valve is too large, the motion amplitude of the protective cover is too large, and the protective cover collides with other parts and even is damaged is avoided, and the use stability and practicability are high.
本发明提供一种液压控制系统、电池箱防护系统及宽体车。本发明利用液压执行元件驱动车辆的防护盖运动,并利用换向阀实现防护盖的运动换向,从而防护盖可以打开或关闭换电通道,当关闭换电通道时,可以在换电通道处形成对电池箱的防护,避免外部石块经过换电通道运动至与电池箱发生碰撞;并且,在换向阀的供油油路上设置蓄能器,在遇到特殊情况例如液压源无液压力时,可以通过蓄能器供给液压油,使得液压执行元件仍然可以动作或保持动作状态,提高液压控制系统的续航能力;蓄能器还可稳定供油油路的压力,避免换向阀的工作油口之间的压差波动过大,导致防护盖运动幅度过大而与其他部件发生碰撞甚至损坏,本发明使用稳定性高,实用性强。
