Abstract

The invention provides a variable-thickness automobile roof middle cross beam. A roof middle cross beam body is of a thin-wall structure and sequentially comprises a left body section, a left transition section, a middle body section, a right transition section and a right body section. The left body section and the right body section are connected with an automobile side body column B and have a uniform thickness. The left transition section and the right transition section are of a continuous variable-thickness structure and become smaller in thickness from the two ends to the middle body section. The middle body section is the thinnest portion of the roof middle cross beam. According to the variable-thickness automobile roof middle cross beam, by means of the design that parts of different thicknesses are arranged along an automobile body in the Y axis direction, the safety requirements for collision resistance and pressure resistance of the roof middle cross beam are met, and the design of light parts can be achieved at the same time.

Description

technical field [0001] The invention belongs to the field of design and manufacture of auto parts, and in particular relates to a middle beam of a variable-thickness auto roof cover and a manufacturing method thereof. Background technique [0002] The beam in the roof of the car is horizontally supported under the roof and connected between the left and right sides of the car body, mainly to strengthen the roof and fix internal parts. The design section of the cross beam in the top cover is usually "W" shape, and the beam and the top cover are connected by expansion glue, which can strengthen the local rigidity of the top cover. The beam in the top cover mainly bears the pressure during top pressure, side impact and rollover, and it plays an important role in the strength of the top cover, the collision of the whole vehicle, and the torsional stiffness of the whole vehicle. In order to improve the performance of the whole vehicle, a strong roof beam is usually designed, and...
