The invention discloses a connecting device for a vehicle body and a vehicle frame of a vehicle, which comprises connecting brackets and positioning plates, wherein each connecting bracket comprises a main surface and a side surface; a strip-shaped hole extending vertically is formed in the main surface; a first wash board structure at least covering the strip-shaped hole is arranged on the main surface; a transverse hole of which the axis is parallel to the main surface is formed in the side surface; a through hole is formed in the middle of each positioning plate, and a second wash board structure matched and meshed with the first wash board structure is arranged on one side surface of the positioning plate; the connecting brackets are connected with a middle passage of a vehicle body floor through fastening pieces; and the positioning plates and the connecting brackets are fixedly connected with a cross beam of the vehicle frame through fastening pieces to enable the first wash board structures and the second wash board structures to be mutually meshed. The connecting device is simple and reasonable in structure and convenient to mount, can effectively reduce the noise during the driving of the vehicle, improves the comfort for driving and riding the vehicle, effectively reduces the amount of upward deformation of the vehicle body floor and the possibility of injury to passenger bodies, and is suitable for the use of passenger vehicles.
Description
technical field [0001] The invention relates to an automobile body frame connecting device. Background technique [0002] At present, the connection between the car body floor and the frame is usually achieved through fasteners and the frame at several positions where the left and right sides of the body floor are in contact with the frame longitudinal beams; and in the longitudinal middle of the body floor There is no connecting structure between the part and the frame; this results in that the outer mounting feet of the car driver's seat and the passenger seat can be fixedly installed at the connection between the body floor and the longitudinal beams or directly connected to the longitudinal beams of the car, while the inner mounting feet are Can only be installed in the longitudinal center of the body floor. Since there is no connecting structure between the longitudinal middle part of the body floor and the vehicle frame, and the rigidity of the body floor itself is li...
