The invention belongs to the technical field of shopping cart equipment, in particular to a storage battery assisted stair climbing multifunctional shopping cart. The shopping cart is characterized bycomprising a vehicle body chassis, a driving wheel train which is arranged below the vehicle body chassis, a carrying basket which is arranged on the vehicle body chassis, a grip part which is connected with the vehicle body chassis through a support, an operation panel which is arranged on the grip part, a cantilever beam which is fixedly connected with the vehicle body chassis, a storage battery which is arranged on the cantilever beam, and a horn which is arranged on the front portion of the vehicle body chassis. The triangular wheel serves as a research object, power is provided by the direct-current motor during driving, manual push and pull can be achieved only by stopping the direct-current motor from moving when the triangular wheel is converted into a manual mode, and the triangular wheel push-pull mechanism is suitable for an electric driving mode and a non-electric driving mode; in addition, the span between any two triangular wheels is larger than the height of a single-step stair, and it can be guaranteed that the stair climbing effect is achieved through free reverse rotation of the triangular wheels.
本发明属于购物车设备技术领域,尤其是涉及一种蓄电池助力攀爬楼梯多功能购物车,其特征在于包括车身底架,设置在此车身底架下方的驱动轮系,设置在车身底架上的载物筐,与车身底架通过支架连接的握把件,设置在此握把件上的操作面板,与车身底架固定连接的悬臂梁,设置在此悬臂梁上的蓄电池,设置在车身底架前部的喇叭。本发明以三角轮为研究对象,驱动时由直流电机提供动力,而转换成手动时只需让直流电机停止运动,即可实现手动推拉,不仅适用电力驱动模式,还可适用于无电力驱动模式;另外,三角轮中任意两轮间跨度均大于单阶楼梯高度,能够确保通过三角轮自由反转实现爬楼效果。
