The invention discloses a trailer hook assembly based on a 10-meter pure electric city bus and a using method of the trailer hook assembly. The trailer hook assembly comprises a fixing shaft pin, a positioning pin, a spring and a body support; the bottom end of the fixing shaft pin circumferentially protrudes to form a base, a through hole is axially formed in the top end of the fixing shaft pin,the spring sleeves the bottom of the fixing shaft pin, and the positioning pin penetrates through the through hole to be connected with the fixing shaft pin; the body support is composed of a U-shapedfixing part, an upper cover plate and a lower cover plate, and the upper cover plate and the lower cover plate are symmetrically fixed to the upper portions of the outer sides of the two side walls of the U-shaped fixing part and overlapped with the side walls of the U-shaped fixing part; and the two side walls of the upper cover plate, the two side walls of the lower cover plate and the two sidewalls of the U-shaped fixing part are provided with connecting holes corresponding to the fixing shaft pin and the positioning pin, and the fixing shaft pin penetrates through the connecting holes tobe connected with the body support. According to the trailer hook assembly based on the 10-meter pure electric city bus and the using method of the trailer hook assembly, the workload of machining and welding is reduced, the manufacturing and processing cost is reduced, the welding consistency and the welding strength are ensured, and the problem of the maintenance and use cost of the whole vehicle is thoroughly solved.
