A collision guiding device for a railed recreational vehicle comprises collision buffering mechanisms, linear bearing blocks and guiding reminding mechanisms, wherein the collision buffering mechanisms are provided with collision wheel supports with sliding shaft holes and connected onto the linear bearing blocks, and the linear bearing blocks are symmetrically distributed and externally connected on beams at the bottom of the front end of a frame. Each guiding reminding mechanism comprises a steering knuckle, a connecting rod and a slider-crank mechanism provided with a slider shaft with a compression spring II and is sleeved on the sliding shaft hole of the collision wheel support of the corresponding collision buffering mechanism through the corresponding slider shaft, one steering knuckle is externally connected with a steering system of the vehicle, and the steering system is connected with a steering wheel. The collision guiding device is simple in structure and low in manufacturing cost, collision can be buffered, tires are protected, noise generated in collision is weakened, the steering knuckles are pushed to do small-angle movement by the aid of the compression springs when the vehicle seriously deviates from rails, a driver is reminded of turning in corresponding directions, and the problem that hands are hit due to large-amplitude rotation of the steering system is avoided.
