Abstract

The invention discloses a sectional type electric logistics vehicle frame structure capable of realizing rapid replacing of power batteries. The structure includes a front section longitudinal beam, amiddle section upper longitudinal beam, a middle section lower longitudinal beam and a rear section longitudinal beam; the front section longitudinal beam and the rear section longitudinal beam are provided with leaf spring installation support seats; the seats are provided with crossbeams to connect with the left and right longitudinal beams; the front ends and rear ends of the middle section upper longitudinal beam and middle section lower longitudinal beam form a closed frame structure respectively through the connection of the crossbeams, inclined pull rods and vertical columns; the lowerpart of a battery pack installation frame structure is provided with slideways; and the middle section battery pack installation frame structure is connected to the frame front section longitudinal beam and the frame rear section longitudinal beam through connecting pieces, so that the sectional type frame structure can be formed. The sectional type frame structure can be formed through the framefront section, middle section and rear section, so that the installation of parts such as a vehicle suspension system and the battery packs can be realized; and the frame middle section battery packinstallation frame structure can be suitable for the installation of the battery packs with different specifications, the arrangement space of power batteries can be increased, and the rapid replacingof the power batteries can be realized.

Description

technical field [0001] The invention relates to a frame of an electric logistics vehicle, more specifically relates to a frame structure of an electric logistics vehicle capable of quickly replacing a power battery, and belongs to the technical field of light trucks. [0002] technical background [0003] For pure electric logistics vehicles, its biggest feature is that the power system has become an electronic control unit, drive motor and power battery. In order to ensure the mileage, the power battery is not only bulky, but also weighs about a quarter of the weight of the vehicle. The layout of the power battery has a great influence on the vehicle weight, axle load distribution and vehicle performance (tire load, braking performance, suspension system and vehicle attitude). In addition, the current charging time of pure electric logistics vehicles is long and the operating efficiency is low. In the development and design of the pure electric logistics vehicle frame stru...
