Description

Technical Field

[0001] The utility model relates to the technical field of recreational vehicles, in particular to a folding ladder at the rear of a recreational vehicle. Background Art

[0002] A recreational vehicle (RV) is a mobile living and travel facility that combines living and transportation functions. It is usually made up of a truck chassis or a specially designed chassis, equipped with various living facilities, such as beds, kitchens, toilets and storage space, etc. RVs can provide comfortable living conditions and allow people to enjoy the convenience of home while traveling. The specific definition of RVs varies according to the laws and standards of different countries and regions, but generally includes the following types: Class A RVs: Also known as luxury RVs, they are the largest and most luxurious RVs. They usually have a living space similar to an apartment, equipped with a separate bedroom, kitchen, bathroom and lounge area, etc. Class B RVs: Also known as Campervans or Camper Vans, they are usually based on truck chassis or large truck chassis and are modified to become vehicles that can be used for living. They are smaller than Class A RVs, but still have basic living facilities. Class C RVs: Also known as Cab-overs Motorhomes are usually based on a truck chassis with a living space behind the cab. They are between Class A and Class B RVs. They have a certain living space and are more flexible and convenient than Class A RVs. Due to the high height of the RV, a ladder is required to assist in entering the RV.

[0003] The existing RV ladders have relatively simple functions and are mostly placed outside the vehicle body, often exposed to wind and rain. On the one hand, this reduces the service life of the ladder, and on the other hand, it is not conducive to mounting other components on the RV. For this reason, we propose a folding ladder at the rear of an RV to solve the above problems. Utility Model Content
