Description

Technical Field

[0001] The utility model belongs to the technical field of truck frames, and in particular relates to a truck frame with a power battery mid-mounted. Background Art

[0002] In today's society, the logistics and transportation industry is booming, and with the popularization of new energy vehicles in the country, the demand for new energy cargo trucks is increasing year by year. In order to ensure the safety performance of the vehicle's operation, the power battery is placed in the middle of the frame longitudinal beam. After matching with the upper cargo box, side protection is still required to ensure the personal safety of pedestrians. No other devices can be installed on the inside of the side protection, resulting in a waste of space in the vehicle chassis itself.

[0003] Because the power battery is placed in the middle of the frame longitudinal beam, the side of the vehicle becomes a non-integrated structure, and there is a problem of large wind resistance coefficient during driving, resulting in energy waste and failure to better save energy and reduce emissions. For the driver, some items brought with the vehicle can only be placed inside the cab, making the space inside the cab even more narrow and tight, without a comfortable driving environment, and unable to experience a comfortable driving experience. Moreover, placing the brought-with items inside the cab will cause serious safety accidents during the driving of the vehicle, posing a safety hazard. Utility Model Content
