Front floor lower beam connecting structure of battery-changing type electric vehicle body

Abstract

The invention discloses a front floor lower beam connecting structure of a battery-changing type electric vehicle body. The front floor lower beam connecting structure comprises a vehicle body front floor, a front floor lower beam is arranged in front below the vehicle body front floor, the two ends of the front floor lower beam are fixedly connected with front floor side longitudinal beams, the middle of the front floor lower beam is fixedly connected with a middle channel, the rear ends of vehicle body front longitudinal beams are fixedly connected with the front floor lower beam, and the front ends of front floor inner longitudinal beams are fixedly connected with the front floor lower beam. The front floor lower beam connecting structure is simple, convenient to assemble and reliable to use, and installs and fixes a vehicle battery pack without substantially changing a traditional vehicle body structure, meanwhile, longitudinal and transverse rigidity of the lower portion of an electric vehicle body floor is guaranteed, the performance of resisting front face and side face collision of the vehicle body is effectively improved, the safety and the stability of an electric vehicle are improved, the manufacturing cost of the electric vehicle is lowered, and the consumed tooling time for the electric vehicle is shortened.

Description

technical field [0001] The present invention relates to a connection structure of the lower crossbeam under the front floor of the automobile body, in particular to a connection structure of the lower crossbeam under the front floor of the battery swap type electric vehicle body, including the front floor of the vehicle body; A front floor side beam is arranged at the end; a middle channel parallel to the front floor side beam is arranged in the middle of the front floor of the vehicle body; The inner longitudinal beam of the floor, the inner longitudinal beam connecting plate; the front floor of the vehicle body is provided with a seat beam above the direction of vehicle travel; the front longitudinal beam of the vehicle body is arranged at the front end of the front floor of the vehicle body along the direction of vehicle travel The inner longitudinal beam of the front floor is arranged in the middle of the front floor of the vehicle body; one end of the inner longitudinal b...

Problems solved by technology

Although this invention proposes a frame structure for the front floor system of an electric vehicle, which improves the strength of the frame for installing the battery assembly and the stability of the lower body during the driving of the electric vehicle, this invention cannot effectively use the front floor structure of a traditional car. If the invention is installed on the electric vehicle, the body will be greatly modified, thereby increasing the manufacturing cost; meanwhile, the invention cannot effectively improve the anti-collision performance of the side and front of the electric vehicle body to ensure the safety of the electric vehicle
