Technical Field

The invention relates to a connecting structure of vehicle frameworks.

Background

The body frame comprises a side wall and a large top arranged on the side wall, the side wall comprises stand columns and side longitudinal beams which are arranged perpendicular to each other, the large top is supported on the side wall through a top cross beam, and the top cross beam and the stand columns are located in the same vertical plane.

When the vehicle is impacted laterally, the side wall of the vehicle is impacted and is easily disconnected with the top cross beam, so that the large top falls off, and potential safety hazards are generated; meanwhile, the large roof carries an overhead air conditioner, a skin, an interior trim and the like, the weight is large, when the vehicle is subjected to impact vibration in the vertical direction, the rigidity of the top beam and the stand column in the vertical direction is low, the attenuation of the vibration is slow, and low-frequency noise is easy to generate, so that the strength of the connecting structure of the top beam and the side wall is very critical.

Disclosure of Invention

The invention aims to provide connecting structures of vehicle frameworks to enhance the connecting strength among side longitudinal beams, top cross beams and upright columns of a vehicle.

In order to solve the technical problem, the technical scheme of the connecting structure of the vehicle framework is as follows:

the connecting structure of the vehicle framework comprises a stand column and a side longitudinal beam which are arranged in a mutually perpendicular mode, and further comprises a top cross beam which is positioned in the same vertical plane, wherein the side longitudinal beam is positioned on two sides of the stand column in the front-back direction of the vehicle, a connecting plate is arranged on the end face of the stand column, and the connecting plate is fixedly connected with the end face of the stand column and the side face of the side longitudinal beam.

The technical scheme has the beneficial effects that: the end face of the top cross beam is fixedly connected with the end face of the stand column through the connecting plate, meanwhile, the connecting plate is fixedly connected with the side face of the side longitudinal beam, the top cross beam, the stand column and the side longitudinal beam are connected into a whole through the connecting plate, the contact area among the top cross beam, the stand column and the side longitudinal beam are increased, the structural strength of the joints of the top cross beam, the stand column and the side longitudinal beam is enhanced, and therefore the structural strength of the vehicle framework is enhanced.

And the side of the connecting plate, which is far away from the side longitudinal beam, is provided with a reinforcing rib connected with the top cross beam, and the reinforcing rib can enhance the connection strength of the connecting plate and the top cross beam in the lateral direction of the vehicle, so that the shear resistance of the vehicle framework is improved.

The reinforcing ribs are triangular rib plates. The triangular rib plate has simple structure and low cost.

And the side surfaces of the upright post and the top cross beam are also provided with reinforcing plates for connecting the upright post and the top cross beam. The reinforcing plate can strengthen the connection strength between the upright post and the top cross beam, and the connection rigidity between the upright post and the top cross beam is high.

And the reinforcing plate is provided with a reinforcing bulge which is in the same direction as the extending direction of the upright post. The reinforcing protrusions can enhance the rigidity of the connecting part of the upright post and the top cross beam, resist the deformation of the top cross beam and the upright post during bending, and are beneficial to the attenuation of large-top vibration.

The reinforcing plate is provided with a bending bulge, and the reinforcing bulge is formed by the bending bulge. The bending bulge is simple to manufacture.

And the reinforcing plate is also provided with an avoiding groove for avoiding the connecting plate.
