Stretching and retracting device for recreational vehicle

Abstract

The invention discloses a stretching and retracting device for a recreational vehicle. The stretching and retracting device comprises a vehicle chassis and a vehicle carriage, wherein a telescopic vehicle carriage horizontally moving relative to the vehicle carriage is arranged on one side of the vehicle carriage and connected with the vehicle carriage through a sliding mechanism. The stretching and retracting device is characterized in that two support rods are arranged on the outer side of the lower end of the telescopic vehicle carriage, one support rod is arranged at the front end of the telescopic vehicle carriage, the other support rod is arranged at the rear end of the telescopic vehicle carriage, and the support rods are connected with the sliding mechanism. The stretching and retracting device has the benefits as follows: when the vehicle stops, the telescopic vehicle carriage can extend out of the vehicle carriage, the volume of the carriage becomes the largest, the capacity of the carriage is greatly increased, accordingly, passengers can live, recreate and work in the carriage easily, wider activity space is provided for the passengers, the two support rods on the outer side of the lower end of the extended telescopic vehicle carriage can guarantee stability of the carriage of the recreational vehicle in the stretching and retracting process, and the safety is improved.

Description

technical field [0001] The invention belongs to an improvement to a car body, and in particular relates to a telescopic device for a caravan. Background technique [0002] At present, for cars with larger compartments produced and used at home and abroad, such as: RVs, the compartment capacity of the compartments is generally fixed, and the compartments of some RVs are longitudinally telescopic to increase the compartment capacity Tolerance, such as Chinese patent 01254800.6 discloses a car with a variable car capacity that adopts the above method. However, the above-mentioned method of changing the compartment capacity cannot meet people's increasing requirements for car functions, especially realizing office and life in the car, and its structure is also relatively complicated. For the setting of toll booths, the caravan cannot be super high, super wide or overweight when driving, and when it stops and is used as a "housing", we need it to provide enough space to meet peo...

However, the above-mentioned method of changing the compartment capacity cannot meet people's increasing requirements for car functions, especially realizing office and life in the car, and its structure is also relatively complicated. For the setting of toll booths, the caravan cannot be super high, super wide or overweight when driving, and when it stops and is used as a "housing", we need it to provide enough space to meet people's basic needs; another convenience, If the expansion device added to the caravan is too complicated or heavy, it will increase the difficulty of installation and control, and increase the energy loss of the car. At the same time, the stability of the caravan after extension cannot be guaranteed, which may pose a safety hazard.
