Description

Technical Field

[0001] The utility model relates to the technical field of RV support, in particular to an electric balance support system. Background Art

[0002] Since the RV itself is heavy and has high potential energy, the parking legs need to be strong enough to meet the parking needs of the RV. Therefore, in order to improve its load-bearing capacity, the existing RV parking leg devices have complex structures, large volumes, and high processing and manufacturing costs. Especially when it is necessary to use its support, the operator needs to squat and manually adjust the lowering of each leg and its lowering height to meet the RV's stable parking needs. The entire adjustment operation process is complicated, time-consuming and labor-intensive.

[0003] The existing publication number CN216805399U discloses an automatic leveling RV outrigger, comprising a fixed base connected to the RV, the fixed base is hinged to one end of the support frame, the other end of the support frame is hinged to the free end of the electric push rod piston rod and the support foot, the electric push rod base is rotatably connected to the fixed base, and the fixed base is provided with a limit switch and an outrigger control switch, and the limit switch is connected with the outrigger control switch signal. The automatic leveling RV outrigger of the utility model drives the opening and closing of the support frame through the electric push rod. After the support frame is opened, the electric push rod, the support frame and the fixed base form a triangular structure with good stability and simple structure. The fixed base is provided with a limit switch and an outrigger control switch. When the electric push rod encounters resistance during the extension and retraction process and the support foot touches the ground, the limit switch works to lock the electric push rod, and at the same time, the outrigger control switch locks the support frame, completing the locking of the support leg, so that the outrigger is effectively released from the ground.

[0004] When the support frame in the prior art is retracted, the support frame and the support legs are prone to shaking, and a large abnormal noise is generated during shaking. Therefore, we propose an electric balancing support system. Utility Model Content
