According to the mode that double prods are used for supporting a sledge on ice and a snowfield, the self-propelled roller skating vehicle is not limited by spring, summer, autumn and winter and can do the same movement as the sledge in a square, a park and a common road through forward stretching and backward bending of two arms, synchronous power generation and dual drive without the prods the child tricycle can be self-driven and quickly advance by utilizing the conversion effect of a driving rod, a driving rod loose joint, a driving arm, an arc-shaped rack, a gear and a flywheel. The self-propelled roller skating vehicle changes the characteristics that a common child tricycle is steered by hands, a single driving arm is short and large in resistance, and a child easily falls down due to the lack of centripetal force and losing balance during turning. The self-propelled roller skating vehicle has the characteristics that the double-pedal steering pedal is used for forwards changing power generation and steering, the vehicle seat can swing left and right, the double-arm synchronous power generation dual-drive driving arm is long and labor-saving, the centripetal force is automatically adjusted to be balanced during turning, and the roller skating vehicle is not easy to fall down; and the self-propelled roller skating vehicle can be decelerated and braked by stepping on the brake pedal.
自行旱冰车是依据利用双签子在冰上、雪地上支爬犁的模式,发明制作出不受春夏秋冬季节的限制,在任何地区,都能够在广场、公园、普通道路上,都可以利用双臂前伸后屈同步发力双驱动做支爬犁一样的运动,但不用签子,利用驱动杆、驱动杆活接、驱动臂、弧形齿条、齿轮和飞轮的转换作用,就可以自驱动,快速前行的儿童三轮自行车,自行旱冰车改变了普通儿童三轮自行车用手转向、用脚变换发力单驱动驱动臂短阻力大、转弯时缺少向心力失去平衡易摔倒的特性,自行旱冰车具有用双脚蹬转向踏板向前变换发力转向、车座可以左右摆动、双臂同步发力双驱动驱动臂长省力、转弯时自动调整向心力平衡不易摔倒的特性,并且可以用脚踩刹车踏板减速、刹车。
