The invention provides a front protection beam structure for an automobile, and relates to the field of vehicle and pedestrian protection. The front protection beam structure for the automobile comprises a rear beam, a front beam is arranged at the top of the rear beam, a protection mechanism is arranged between the rear beam and the front beam, the protection mechanism comprises an energy absorption box, a straight cylinder is arranged in the energy absorption box, the straight cylinder is sleeved with a return spring, a straight rod is arranged in the straight cylinder, a mounting frame is arranged at the top of the return spring, and a connecting rod is arranged at the top of the mounting frame. A limiting plate is arranged on the back of the mounting frame, a sliding block is arranged on the front face of the limiting plate, a hinge rod is fixedly connected to the front face of the sliding block, a four-rod assembly is arranged at the top of the mounting frame, and a first intersection, a second intersection and a third intersection are formed on the four-rod assembly. According to the front protection beam structure for the automobile, protection on pedestrians is improved as much as possible, part of energy which cannot be absorbed can be released when the front protection beam structure bears large impact force, and the situation that people in the automobile suffer from a large amount of impact force due to structural collapse is avoided.

    本发明提供一种汽车用前保护梁结构,涉及车辆及行人保护领域。该汽车用前保护梁结构包括后部梁,后部梁顶部设有前部梁,后部梁与前部梁之间设有保护机构,保护机构包括吸能箱,吸能箱内部设有直筒,直筒外部套设有回位弹簧,直筒内部设有直杆,回位弹簧顶部设有安装架,安装架顶部设有连接杆,安装架背部设有限位板,限位板正面设有滑块,滑块正面固定连接有铰接杆,安装架顶部设有四杆组件,四杆组件上形成有第一交叉处、第二交叉处和第三交叉处。该汽车用前保护梁结构尽可能的提高对行人的保护,在经受大的冲击力时,可以释放部分不能吸收的能量,避免结构溃散而导致车内人员的受到大量冲击力作用。
