The invention relates to the technical field of wheel fenders, and discloses a mountain bike fender capable of preventing riding safety from being affected in rainy days. The mountain bike fender comprises a fender body, an expansion device is fixedly mounted at the tail end of the fender body, the expansion device comprises an expansion plate, an expansion cavity is formed in the expansion plate, an expansion electromagnet is fixedly mounted in the expansion cavity, a rotary connecting piece is slidably mounted in the expansion cavity, and an expansion spring is fixedly mounted on the inner side of the rotary connecting piece. According to the mountain bike fender capable of preventing the riding safety from being influenced in the rainy days, through the arrangement of the expansion deformation device, when a user rides in a muddy environment in the rainy days, the fender is in a tilting state through tensile deformation of the connecting end, so that the fender has a better interception effect on mud splashed upwards, meanwhile, the warped fender is started through the tail end expansion device, the expansion plate is pushed to stretch out, and therefore the protection range of the fender is enlarged, and the interception range of the fender to mud stains and the like is widened.

    本发明涉及车轮挡泥板技术领域,公开了一种可避免雨天影响骑行安全的山地车挡泥板,包括挡泥板体,所述挡泥板体末端固定安装有扩展装置,所述扩展装置包括扩张板,所述扩张板内设有扩展腔,所述扩展腔内固定安装有扩展电磁铁,所述扩展腔内滑动安装有转动连接件,所述转动连接件内侧固定安装有扩展弹簧;本发明的一种可避免雨天影响骑行安全的山地车挡泥板通过扩展变形装置的设置,当在雨天泥泞环境骑行时,通过连接端拉伸变形,使得挡泥板处于翘起状态,从而使得挡泥板对向上飞溅的泥渍拥有更好的拦截效果,同时翘起后的挡泥板通过末端扩展装置启动,推动扩展板伸出,从而使得挡泥板的防护范围加大,提高挡泥板对泥渍等的拦截范围。
