Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

A driving device of a recreational vehicle expanding mechanism is shown in figures 1-4 and comprises a base 1, a driving shaft 2, a driving gear 3, a rack 4, a guide mechanism 5 and a motor 6, wherein two fixing blocks 7 are arranged on the base 1 at intervals, the driving shaft 2 is arranged on the fixing blocks 7, the guide mechanism 5 is installed on the fixing blocks 7, the rack 4 is arranged on the guide mechanism 5, the driving gear 3 is arranged on the driving shaft 2 and is meshed with the rack 4, the driving shaft 2 is driven to rotate by the motor 6, and the driving gear 3 is driven to drive the rack 4 to horizontally move along the guide direction of the guide mechanism 5. The expansion box for the motor home is arranged on the rack 4, and the expansion box is driven to move horizontally by the two racks 4 arranged at intervals.

In one embodiment, as shown in fig. 1-4, the rack 4 comprises a bar-shaped body having a continuous "S" shaped tooth slot 41 recessed into the bottom thereof. Through above-mentioned structure for the one end of each driving tooth on the rack all is connected with the side, has increased its intensity, and reduces the material and use, and then reduces rack weight, in order to reach light-weighted effect. Preferably, a cavity 44 is arranged in the strip-shaped body; i.e. further reducing the weight of the rack 4.
