Problems solved by technology

The size of the trunk opening is limited, and the battery needs to be taken out by rotating and tilting. There is a potential danger of liquid leakage, and the loading effect is also not good. At the same time, considering the weight of the battery is about 150kg, it must be removed by mechanical devices, so the layout requires Leave enough working space for the manipulator stroke, which requires re-development of the lifting tool to rotate the battery, increasing production costs

Embodiment Construction

[0012] The trunk of the car is located at the rear of the vehicle body. It includes a base plate 2, two side plates 5, and a rear tail plate 3, and the rear tail plate 3 connects the base plate 2 and the two side plates 5, thereby forming a trunk space. Side plate 5 is fixed, and rear tail plate 3 is movable detachable type, and the two ends of rear tail plate 3 are connected with side plates 5 on both sides by bolts. Divide up and down two cavities 6,7 in the trunk, i.e. two layers of space, the upper part is used as a luggage case for storing articles, and the lower part is a battery storage box specially used for placing high-voltage batteries.

[0013] The high-voltage battery 1 is completely laid out on the lower layer of the trunk, utilizing the space of the spare tire compartment of the prototype car, without changing the structure of the car body, and without occupying the storage space of the trunk, so as to meet the needs of market customers. In addition, the high-v...

Abstract

The invention discloses an automobile trunk convenient to disassemble and assemble a high-voltage battery, comprising a bottom plate, a side plate and a rear tail plate; and the two ends of the rear tail plate are respectively connected with the side plate in a disassembling mode. The automobile trunk basically reserves the trunk structure of the prototype automobile. As the connection of the rear tail plate and the two side plates uses a disassembling connection instead of the original welding mode, the battery in-out port is enlarged, simultaneously the direction of assembling and disassembling of the high-voltage battery is changed too, so that the battery can be directly and smoothly taken in and out without being inclined.. In addition, the high-voltage battery is arranged at the lower part of the trunk and vacates all the upper space; and the descend of gravity center is beneficial to the operating stability and side-tipping stability of the whole automobile.

Description

technical field [0001] The invention relates to a trunk of a car, in particular to a trunk of a hybrid electric car. Background technique [0002] With the shortage of global oil resources and the needs of environmental protection, hybrid electric vehicles have become an important trend in the development of modern automobiles, and high-voltage batteries, one of the power sources for hybrid electric vehicles, are the key technology for the development of hybrid electric vehicles. With the development of modern automobile technology, people have higher and higher requirements for the utilization rate of electric energy and cruising range of plug-in hybrid electric vehicles. In this case, the volume and The weight is greatly increased. At the same time, when the high-voltage battery is arranged in the whole vehicle, many factors such as the distribution of front and rear axle loads, the direction of the high-voltage wiring harness, collision safety, the layout of the battery c...
