Description

Technical Field

[0001] The utility model relates to the technical field of RVs, and more specifically, to an electric folding ladder for RVs. Background Technique

[0002] An RV, also known as "a home on wheels", combines the two major functions of "a house" and "a vehicle", but its nature is still a vehicle, which is a movable vehicle with essential home facilities. RVs are fashionable vehicle types introduced from abroad, and the home facilities on them include: bedding, stoves, refrigerators, cabinets, sofas, dining tables and chairs, washing facilities, air conditioners, TVs, stereos and other furniture and appliances, which can be divided into a driving area, a living area, a bedroom area, a sanitary area, a kitchen area, etc. Since RVs need to adapt to various road conditions, the chassis of their carriages is often made relatively high, and people need to step on a ladder to enter the carriage.

[0003] Existing ladders for RVs are generally fixed to the pedals on the outer wall of the carriage and usually adopt manual folding, which is time-consuming and laborious. In view of this, we propose an electric folding ladder for RVs. Content of the Utility Model
