Tray box capable of achieving rapid replacement of power battery of pure electric engineering vehicle

Abstract

The invention discloses a tray box capable of achieving rapid replacement of a power battery of a pure electric engineering vehicle. The tray box comprises a top plate, a bottom plate and a side plate, wherein the top plate and the bottom plate are oppositely arranged, positioning blocks and threaded holes are formed in the top end surfaces of both the top plate and the bottom plate, trapezoidal positioning convex strips and threaded holes are formed in the side end surfaces of both the top plate and the bottom plate, limiting pieces are further formed on the bottom surface of the bottom plate, the side plate comprises a first side plate and a second side plate which are adjacently arranged, through holes are formed in the first side plate and the second side plate respectively, trapezoidal positioning grooves are formed in the top and the bottom of both the first side plate and the second side plate, the positioning grooves are matched with the positioning convex strips correspondingly, the first side plate and the second side plate are in bolted connection with both the top plate and the bottom plate through the through holes, and observation holes are formed in the first side plate. According to the tray box, the structure is simple, the quality is stable, the space is saved, the using cost and the failure rate of the power battery are reduced, the maintenance of the power battery is facilitated, and the service life of the power battery is prolonged.

Description

technical field [0001] The invention relates to the technical field of design and manufacture of pure electric engineering vehicles, and more specifically relates to a pallet box capable of quickly replacing power batteries of pure electric engineering vehicles. Background technique [0002] At present, with the rising calls for energy saving, emission reduction and energy dependence reduction, coupled with the pressure brought by rising oil prices to the traditional automobile industry, pure electric engineering vehicles will gradually become the development trend of the future automobile industry. [0003] In terms of characteristics and functions, pure electric engineering vehicles have the following outstanding advantages compared with fuel-powered engineering vehicles: such as zero exhaust emissions, high energy utilization, simple structure, low noise, free charging time, and can effectively smooth the peak-valley difference of the power grid. However, while affirming ...

AI Technical Summary

Problems solved by technology

However, while affirming the advantages of pure electric engineering vehicles, it should also be seen that there are still disadvantages that need to be solved urgently in pure electric engineering vehicles, such as short cruising range, which can hardly maintain a complete single-shift full-load operation; Long time, each effective charging time is 5-6 hours on average; battery life is short, as short as two years, as long as four years; these defects greatly limit the large-scale application of pure electric engineering vehicles
