Description

Land loading and unloading exchange models

technical field

The utility model relates to an automobile technology, in particular to a floor loading and unloading exchange vehicle type.

Background technique

Swappable car refers to a new type of car that can be quickly disassembled or installed between the car or other facilities and the car chassis, so as to achieve the purpose of exchanging cars or other facilities without parking, and improve the overall efficiency of the vehicle. At present, most of the interchangeable car structures on the market adopt a set of airbags or a hydraulic lifting system on the chassis to lift the car to be replaced to a height of about 350mm; then put down the bottom of the car and preset 4 Steel outriggers rest on the ground, the chassis lift system drops and the vehicle drives away from the cabin.

Chinese patent application 2015108956535 discloses a vehicle-mounted loading and unloading method and device for container loading and unloading, which belongs to the field of container loading and unloading methods and devices. The method and device are based on three assemblies: one is fixed on the top of the frame by welding or bolting A subframe assembly; a bracket assembly used to lift and load the container; a lifting assembly connected between the subframe assembly and the bracket assembly for lifting the bracket assembly. The loading and unloading method of the utility model does not need forklifts and hoisting equipment no matter whether the container is loaded or unloaded, and the container frame is raised to the working height of the bracket assembly by using the support frame to realize the purpose of loading and unloading.

But in this patent application, also need to pay special attention not to scrape the carriage support leg when vehicle drives away.
