The invention relates to a linear variable coil density vibration energy harvesting device, a rail vehicle and an energy harvesting method, and the device comprises a housing, and a permanent magnet,a multi-turn induction coil and a coil density adjustment structure which are disposed in the housing, and the permanent magnet and the induction coil are located in a first cavity. The coil density adjusting structure comprises a plurality of movable blocking pieces, a plurality of elastic pieces in a compressed state and an adjusting blocking piece fixed to the permanent magnet, the adjusting blocking piece is matched with the movable blocking pieces to change the coil density, and the permanent magnet does the motion of cutting the plane of the induction coil. Compared with the prior art, kinetic energy generated by a vehicle is converted into electric energy and stored, the electric energy can serve as a distributed power supply of vehicle-mounted monitoring equipment, extra energy does not need to be consumed, and the energy recovery process is not easily affected by the environment; the coil density adjusting structure in the housing can make full use of existing coils, so that the density of the coils around the permanent magnet is always high in the moving process of the permanent magnet, and maximization of output electric energy is achieved.
