Electric watering cart capable of rapidly changing electricity
The invention discloses an electric watering cart capable of quickly changing electricity, which belongs to the technical field of electric watering carts and comprises a bracket internally provided with a battery component and a base fixedly arranged on a frame, a plurality of transversely telescopic pin shafts are arranged on the base, a press-fit surface is arranged on the bracket, and the length of the press-fit surface is not smaller than the assembly error of the bracket and the base. The height of the pressing face is matched with the height of the pin shaft, and the end face of the pin shaft can be in pressing fit with the pressing face. Guide blocks are arranged in the front-back direction and the left-right direction of the base, and the distance between the guide blocks and the pressing face is matched with the assembly error of the bracket and the base. Compared with the assembling mode that a pin shaft is matched with a locking pin hole in the prior art, the mode that the bracket and the base are limited through the guide block, and the pin shaft and the pressing face are assembled in a pressing mode is arranged, the assembling accuracy of the bracket and the base is reduced while the assembling firmness is ensured, and the replacing efficiency of a battery assembly is improved; and the problem of mileage anxiety caused by the reason that the explosion-proof lithium battery cannot be charged underground and the like is solved.
本发明公开了一种可快速换电的电动洒水车，属于电动洒水车技术领域，包括内部装有电池组件的托架和固定设置在车架上的底座，底座上设有若干横向伸缩的销轴，托架上设有压合面，压合面的长度不小于托架与底座的装配误差，压合面的高度与销轴的高度相适配，销轴的端面能与压合面压接配合；底座的前后方向和左右方向均设有导向块，导向块与压合面之间的距离与托架与底座的装配误差相适配；本发明设置导向块对托架与底座进行限位，销轴与压合面压接装配的方式，相对于现有技术中销轴与锁紧销孔配合的装配方式，在确保装配牢固性的同时降低了托架与底座的装配精度，提高了电池组件的更换效率，解决了防爆锂电池不能在井下充电等原因引起的里程焦虑。
