Please refer to FIG. 1 to FIG. 4 , a rotating jacking outrigger includes an outrigger body, at least one rotating mechanism that drives the outrigger body to rotate, at least one jacking mechanism that drives the outrigger body to extend and retract, and at least one power source , the power source drives the rotating mechanism and the jacking mechanism to complete the rotating jacking action. The outrigger is installed on the chassis of the vehicle through the mounting plate 1, the power source is activated, and the rotating mechanism drives the main body of the outrigger to rotate 90 degrees from the horizontal position to the vertical position. The car plays a supporting role. When the outrigger is not working, the main body of the outrigger is contracted and can be fixed from the vertical position to the horizontal position.

The specific structure is as follows:

The power source includes a drive motor 6 and a gear set 8, the output shaft of the drive motor 6 is connected with the gear set 8, and the gear set 8 is connected with the rotating mechanism.

The rotating mechanism includes a main gear 9 and a sub-gear 10 that is toothed with the main gear 9. The main gear 9 is connected to the gear group 8 in the power source. The gear group 8 transmits the power to the main gear 9 and drives the main gear 9 to rotate. The gear 9 drives the auxiliary gear 10 to rotate. The main gear 9 and the auxiliary gear 10 in the present invention are both bevel gears. The auxiliary gear 10 drives the jacking mechanism to work.

The jacking mechanism includes a screw rod 11, one end of the screw rod 11 is connected with the auxiliary gear 10, and the other end of the screw rod 11 is connected with the main body of the outrigger. The rotation of the secondary gear 10 drives the screw 11 to rotate.

The main body of the outrigger includes an outer tube 2 and an inner tube 3, the outer tube 2 and the inner tube 3 are sleeved with each other through the flange 4 and the bushing 5, and the inner tube 3 is connected with the screw rod 11 to realize the sliding expansion in the outer tube 2 to elongate. Or shrink the body of the outrigger. Specifically, the screw rod 11 is arranged in the outer tube 2, and one end of the screw rod 11 is connected to the auxiliary gear 10 through the link shaft 12, and the other end of the screw rod 11 is connected to the inner tube 3 through the nut 13. When the auxiliary gear 10 rotates, The screw rod 11 can be driven to rotate, thereby driving the inner tube 3 to realize telescopic movement in the outer tube 2 .

During operation, the power output by the drive motor 6 is transmitted through the gear set 8 to drive the main gear 9 to rotate.

The rotation of the auxiliary gear 10 can change the main body of the outrigger from the original Rotate 90 degrees from the horizontal position to the vertical position. At this time, the auxiliary gear 10 continues to rotate, driving the inner tube 3 to extend out of the outer tube 2, so that the length of the outrigger becomes longer to adapt to the supporting height of the outrigger for the RV. When the outrigger rotates to the vertical position, the outrigger is stuck by the limiter and remains in a vertical state, preventing the outrigger from continuing to rotate and deviating from the vertical position, causing the supporting force of the outrigger to be distorted and insufficient. When the outriggers are retracted, the outriggers can be retracted and fixed in a horizontal position simply by reversing the driving motor 6 .

Further, the rotating mechanism also includes a transmission shaft 7, the transmission shaft 7 is connected with the main gear 9, and one end of the transmission shaft 7 is a hand-cranked end. When the motor is powered off or the system fails, the outrigger can be retracted by hand, that is, the outrigger. It can be folded electrically or manually.

In order to adapt to supporting the RV on the ground with a slope, the bottom of the inner tube 3 is provided with a ball head 14, a foot fixing plate 15 and a foot plate 16, and the ball head 14 is movably arranged in the foot plate 16 through the foot fixing plate 15, The foot plate 16 can be rotated at a certain angle under the adjustment of the ball head 14 to adapt to the bottom surface of different slopes, so that the outrigger is always in a vertical position to ensure the supporting strength of the outrigger, and the gap between the foot plate 16 and the main body of the outrigger is Can have a certain angle.

Working principle: The initial state is that the outrigger is installed horizontally on the chassis of the car. When the vehicle-mounted fixed locking device is released, the outrigger is driven by gravity and the motor, and the outrigger rotates from the horizontal state to the vertical state, and then rotates to the mechanical limit. , the driving force of the motor is transmitted to the screw rod 11, the stroke is lifted, and the inner tube 3 extends out of the outer tube 2 to support the car. When shrinking, the motor reverses, and the outrigger rotates from the vertical state to the horizontal state. After reaching the limit of the limit block, the vehicle-mounted fixed locking device works, and the inner tube 3 shrinks into the outer tube 2 to complete the shrinkage.
