The invention relates to the technical field of electric vehicle structures, in particular to an electric vehicle front fork shock absorber which comprises a front fork frame, a shock absorption rod connected to the front fork frame and a shock absorption cylinder connected to the shock absorption rod in a sleeving mode, a dustproof ring is arranged at the end of the shock absorption cylinder, and a plurality of dustproof protrusions are arranged on the inner wall of the dustproof ring in the axial direction. A containing ring groove is formed between the dustproof protrusions, and the damping cylinder is provided with protruding parts which enable the dustproof protrusions to abut against the outer wall of the damping rod in the radial direction. The damping rod has the following effects that in the moving process of the damping rod, the multiple dustproof protrusions can achieve the multiple sealing effect and reduce the possibility that impurities enter the damping rod, meanwhile, in the using process, due to the fact that the protruding parts have supporting force in the radial direction, additional abutting supporting force is provided, the overall sealing effect is improved, and the service life of the damping rod is prolonged. Impurities and the like can be blocked outside, so that the sealing performance is improved.

    本申请涉及电动车结构的技术领域,尤其是涉及一种电车前叉减震器,包括前叉架、连接于前叉架的减震杆、套接在减震杆外的减震筒,所述减震筒的端部设置有防尘圈,所述防尘圈内壁沿轴向设置有若干个防尘凸起,所述防尘凸起之间具有容置环槽,所述减震筒具有沿径向将防尘凸起保持抵触在减震杆外壁上的凸起部。本申请具有以下效果:减震杆在运动的过程中,首先多个防尘凸起,可以起到多重密封的效果,降低杂质进去的可能性,同时在使用的过程中,由于凸起部在径向上具有支撑力,从而提供额外的抵触支撑力,使得整体的密封效果提升,能够将杂质一类的东西阻隔在外,提升密封性。
