The invention discloses a vehicle body front bumper buffer structure, which belongs to the technical field of bumpers, and comprises a first cylinder body, a movable rod is arranged in the first cylinder body, the movable rod can axially and radially move in the first cylinder body, and a plurality of first elastic parts are uniformly distributed in the first cylinder body in the circumferential direction; the second elastic part is provided with two end parts, a first supporting part and a second supporting part, the first supporting part and the second supporting part are both located between the two end parts, and the two end parts of the second elastic part are fixed in the movable rod and the first cylinder body correspondingly; through mutual cooperation of buffering mechanisms of the first elastic part in the axial direction and the radial direction, all-directional buffering is provided for the movable rod, in the complex movement process, the movable rod can be subjected to axial and radial impact force at the same time, at the moment, the first elastic part can play a role in the two directions at the same time, and therefore the buffering effect of the movable rod is improved. And the influence of impact and vibration on the vehicle is effectively reduced.
本发明公开了一种车体前保险杠缓冲结构,属于保险杠技术领域,包括第一缸体,第一缸体的内部内置有活动杆,活动杆可在第一缸体内进行轴向移动以及径向移动,第一缸体内周向均匀分布有多个第一弹性部,第二弹性部具有两个端部、一个第一支撑部以及一个第二支撑部,第一支撑部和第二支撑部均位于两个端部之间,第二弹性部的两个端部分别固定在活动杆和第一缸体内,本发明通过第一弹性部在轴向和径向两个方向上的缓冲机制相互协同,为活动杆提供了全方位的缓冲,在复杂的运动过程中,活动杆可能会同时受到轴向和径向的冲击力,这时,第一弹性部能够同时在这两个方向上发挥作用,有效减少冲击和振动对车辆的影响。
