The rear wheel protection device comprises a supporting plate and a rubber plate, the rubber plate is bonded to the lower surface of the supporting plate, spring seats are symmetrically installed at the inclined plane position of the rubber plate, a bottom plate is fixedly connected to the bottom ends of the spring seats, and a metal plate is fixedly connected to the middle position of the lower surface of the bottom plate. The metal plate is arranged in an inclined mode, an assembling groove is formed in the front face of the metal plate, and a permanent magnet is fixedly connected into the assembling groove of the metal plate. The metal plate performs magnetic attraction treatment on metal materials on the road surface in front of the rear wheels under the action of the permanent magnet, so that sharp metal materials on the road surface are effectively reduced, tire puncturing accidents are reduced, and the riding safety is improved; in the riding process, the obstacle clearing roller conducts guiding clearing on obstacles on the road surface, the rear wheels are prevented from directly colliding with the obstacles, and the riding comfort is improved.
本发明公开了一种后轮防脱离变速山地自行车的后轮防护装置,包括支撑板和橡胶板,所述橡胶板粘接在支撑板下表面,所述橡胶板的斜面位置对称安装弹簧座,所述弹簧座底端固定连接底板,所述底板下表面中间位置固定连接金属板,所述金属板呈倾斜设置,所述金属板正面位置开设有装配槽,所述金属板的装配槽内部固定连接永磁体。金属板在永磁体的作用下对后轮前方的路面进行金属材料的磁吸处理,有效的减少路面的尖锐金属材料,降低扎胎事故的发生,提高骑行的安全性;在骑行的过程中,清障辊对路面的障碍物进行导向清除,防止后轮直接与障碍物撞击,提高骑行的舒适度。
