The working method of the multi-size adaptive electric vehicle mudguard of claim 1, wherein: the first fixing frame (21) and the second fixing frame (31) are respectively installed and fixed with the tire axle parts on the corresponding sides; detaching the second shell (206), adjusting the matching position of the first shell (205) and the adjusting plate (200) according to the size of the wheel, so that the length of the fixing frame is matched with the diameter of the wheel, and finally, reinstalling and combining the second shell (206) and the first shell (205);
when the length of the first fixing frame (21) is adjusted, the intermediate piece (1) is synchronously adjusted front and back, and the first extending piece (2) is correspondingly arranged on a throwing path of water drops stained on the wheel; after the position of the middle piece (1) is fixed, bolts penetrate through corresponding slots of the front fork and corresponding positioning rings (162) in the waist-shaped holes (161);
after the fender of the electric vehicle is installed, the positioning pin (203) is embedded into the first positioning hole (202) in an initial state to limit the sliding of the movable plate (4); when the bicycle runs in rainy days or water accumulation road sections, a rider parks by leaning to the side to pull the positioning pin (203) out of the first positioning hole (202), and then the movable plate (4) can slide downwards along the sliding groove (201) to serve as an extension part at the lower end of the first extension piece (2), so that the function of shielding water drops thrown by the wheels is effectively enhanced; when the vehicle runs in a hollow place, the wheels sink to the bottom, and the movable plate (4) further slides towards the ground under the action of inertia, so that water splashing caused by the sinking impact of the wheels is prevented while water drops are shielded, and the leg of a rider and other pedestrians behind the vehicle are protected;
wherein, when the vehicle body is not bumpy, the sinking distance of the movable plate (4) depends on the length compressed by the first spring element (43) under the action of the gravity thereof; when the vehicle body bumps, the movable plate (4) continues to sink due to inertia, when the insert (41) is about to impact the bottom of the sliding chute (201), the insert (41) starts to contact the second spring part (45), the reverse resistance borne by the insert is increased, and the sinking is stopped in time, so that frequent hard impact between the movable plate (4) and the sliding chute (201) can be avoided, and the service life of the part is obviously prolonged; the moving plate (4) then moves upwards from the lowest point, oscillates around the initial position and finally returns to rest.
