Problems solved by technology

[0002] In vehicles such as large passenger cars in the related art, the body frame usually contains cross-connected beam structures such as cross beams and longitudinal beams. Vertical surface connection, the fatigue durability of this type of joint is insufficient, resulting in insufficient connection stiffness and large deformation; there are also some joints that are not only connected with the two vertical surfaces of the beam and the longitudinal beam, but also with the two sides of the beam and the longitudinal beam , the assembly of this kind of joint itself is more troublesome, in addition, the assembly accuracy of the whole vehicle is required to be high, and some unavoidable factors for manufacturing errors and assembly errors lead to more cumbersome assembly and seriously affect assembly efficiency

Abstract

The invention discloses a vehicle body framework joint and a vehicle with the same. The vehicle body framework joint comprises a first sub-joint and a second sub-joint, wherein the first sub-joint andthe second sub-joint are suitable for being installed on a vehicle body framework, the first sub-joint and the second sub-joint are combined in an abutting mode and jointly define a cross beam connecting groove and a longitudinal beam connecting groove, the cross beam connecting groove is suitable for containing a cross beam of the vehicle body framework, and the longitudinal beam connecting groove is suitable for containing a longitudinal beam of the vehicle body framework. According to the embodiment of the invention, the vehicle body framework joint is high in connecting strength, convenient to assemble and high in assembling efficiency.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a body frame joint and a vehicle with the same.
