Problems solved by technology

Welding is labor-intensive, which also leads to a decrease in production efficiency and an increase in cost
Moreover, welding is easy to cause deformation, and the amount of deformation is uncontrollable, and the accuracy of later assembly cannot be guaranteed

Abstract

The invention relates to a modularized light full-bearing passenger car body structure. The modularized light full-bearing passenger car body structure comprises a frame, a car body and a front and back wall structure body. The front and back wall structural body comprises a front wall structure and a rear wall structure. The car body comprises a plurality of annular gantry frameworks which are linearly arranged at fixed intervals, car body structural plates and anti-torque longitudinal beams. The lower ends of the annular gantry frameworks are fixedly connected with the frame. The annular gantry frameworks are connected together through the anti-torque longitudinal beams. The anti-torque longitudinal beams are perpendicular to top beams and side stand columns. The corresponding car body structural plate is fixedly arranged between every two adjacent annular gantry frameworks. The front wall structure is fixed to the annular gantry framework at the front end of the car body. The rear wall structure is fixed to the annular gantry framework at the tail end of the car body. The car body is modularized, the production efficiency can be improved through the modularized production, and rapid assembly and rapid detachment and repair can be achieved.

Description

Technical field [0001] The invention relates to automobile parts, in particular to a modular lightweight full-bearing passenger car body structure. Background technique [0002] Passenger cars are often used for public transportation and group transportation because of their considerable carrying capacity (can carry a large number of passengers and their luggage). The frame of a passenger car is generally composed of structural beams, and in order to ensure the stability of the frame, a large number of structural beams and special parts of different specifications are often required, which affects production efficiency and production costs. At the same time, due to the large number of structural beams, the overall weight of the frame is very large, which increases the fuel consumption of the vehicle. Especially if today's electric passenger cars still adopt the traditional frame, their endurance will definitely be greatly affected. The structural beams of the traditional frame ...
