The invention relates to the technical field of railway vehicles and discloses a connecting structure used for connecting an aluminum honeycomb with an aluminum plate, a cab and a railway vehicle. Theconnecting structure comprises a connecting structure body and a supporting component, wherein a first lap joint position used for connecting the aluminum honeycomb and a second lap joint position used for connecting the aluminum plate are constructed on the upper surface of the connecting structure body, and the longitudinal height difference between the first lap joint position and the second lap joint position is equal to the longitudinal thickness difference of the aluminum plate and the aluminum honeycomb; and the supporting component is arranged on one side of the connecting structure body and extends in the direction away from the connecting structure body, and the supporting component is located below the first lap joint position and used for bearing the aluminum honeycomb. The connecting structure has the advantage that the aluminum honeycomb and the aluminum plate which are different in thickness can be conveniently connected.
Description
technical field [0001] The invention relates to the technical field of rail vehicles, in particular to a connection structure for connecting an aluminum honeycomb and an aluminum plate, a driver's cab and a rail vehicle. Background technique [0002] The current rail vehicles are usually made of aluminum alloy body, and the driver's cab adopts a mixed structure of aluminum plate and aluminum honeycomb. Among them, the aluminum honeycomb is composed of a sandwich-like structure, including the honeycomb core and the upper and lower plates arranged at the upper and lower ends of the honeycomb core. , The thickness of the aluminum plate and the aluminum honeycomb is often different, the welding process between the aluminum plate and the aluminum honeycomb is often poor, and after the aluminum plate and the aluminum honeycomb are directly welded, the connection strength between the aluminum plate and the aluminum honeycomb is often low.
