Cantilevered Vehicle Box Slide-Out System

The present application relates to a cantilevered vehicle box slide-out system, including a cantilevered moving component, a drive device, a connecting plate, a support frame, and bearing boxes, all integrally set inside the bearing boxes located at the lower part of the slide-out box. There is no need to dismantle the vehicle chassis; simply fixing the support frame to the vehicle body allows the slide-out box to be set at the vehicle body's opening. This application can realize the slide-out of the vehicle box, increasing usable space, facilitating convenient installation and removal, and ensuring a neat and aesthetically pleasing appearance.
