Integral kart body frame system

The utility model discloses an integral kart body frame system. The automobile comprises an integrated PP plastic automobile body made of rotational molding. Wherein the frame is formed by welding metal tubes; mounting grooves for containing all metal pipes forming the frame are formed in the bottom of the integrated PP plastic vehicle body in advance. A kart body bearing structure is innovativelydesigned; the utility model discloses an integral kart body frame system manufactured by using a rotational molding process. According to the kart body frame system, the mode that a traditional karttakes a single tubular frame as a main bearing is changed, the integral kart body frame system is beneficial to dispersing stress of the whole kart, the using amount of steel pipe frame materials is reduced under the same condition that the original rigidity of the whole kart is guaranteed, the weight of the whole kart is reduced, and a kart body manufactured through the rotational molding processhas the advantage of being
