Description

Technical Field

[0001] This utility model relates to a rear-mounted two-wheeled motor vehicle frame for RVs, belonging to RV auxiliary components. Background Technology

[0002] Most RVs currently on the market are modified from box-type chassis, with a wide range of built-in appliances and diverse functions for driving and living.

[0003] However, RVs are typically quite tall to accommodate living spaces. Due to height restrictions in urban underground parking garages and other facilities, RVs can only be parked in a limited number of parking lots on the outskirts of the city or within the city itself. This is extremely inconvenient for travelers, who then need to transfer to a car or electric vehicle near their destination to access the RVs.

[0004] Carrying a motorcycle or electric two-wheeler in a motorhome can solve the problem of motorhomes being unable to enter some areas.

[0005] However, motorcycles or electric two-wheelers are too large to fit inside the RV cabin and can only be stored externally. This necessitates the design of an RV frame mechanism that can accommodate two-wheeled motorcycles or electric vehicles.

[0006] Although there are many two-wheeled motor vehicle frames on the market, their structure is not compatible with the structure of the applicant's RV. Summary of the Invention

[0007] To address the aforementioned problems, this invention provides a rear-mounted two-wheeled motor vehicle frame for motorhomes, solving the issue of storing two-wheeled motorcycles or electric vehicles outside the motorhome cabin.
