Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Fig. 1 is a schematic view of the overall structure of the landing leg in the horizontal position according to the present invention; FIG. 2 is a cross-sectional view of FIG. 1; fig. 3 is a schematic view of the overall structure of the support leg in the vertical position according to the present invention; fig. 4 is a cross-sectional view of fig. 3.
Referring to fig. 1 to 4, a rotary jacking leg includes a leg main body, at least one rotating mechanism for driving the leg main body to rotate, at least one jacking mechanism for driving the leg main body to extend and retract, and at least one power source for driving the rotating mechanism and the jacking mechanism to complete a rotary jacking operation. This landing leg passes through mounting panel 1 to be installed on vehicle chassis, starts the power supply, and rotary mechanism drive landing leg main part rotates 90 degrees to vertical position from horizontal position, and climbing mechanism work this moment, the extension of landing leg main part, landing leg play the supporting role to the car, and when the landing leg was out of work, the landing leg main part shrink rotated to horizontal position from vertical position and fixed can.
The specific structure is as follows:
the power source comprises a driving motor 6 and a gear set 8, an output shaft of the driving motor 6 is connected with the gear set 8, and the gear set 8 is connected with the rotating mechanism.
The rotating mechanism comprises a main gear 9 and a pinion 10 meshed with the main gear 9, the main gear 9 is connected with a gear set 8 in a power source, the gear set 8 transmits power to the main gear 9 to drive the main gear 9 to rotate, and the main gear 9 drives the pinion 10 to rotate. The main gear 9 and the pinion 10 in the utility model are bevel gears. The pinion 10 drives the jacking mechanism to work.
The jacking mechanism comprises a screw rod 11, one end of the screw rod 11 is connected with the pinion 10, and the other end of the screw rod 11 is connected with the supporting leg main body. The rotation of the pinion 10 drives the screw rod 11 to rotate spirally.
The landing leg main part includes outer tube 2 and inner tube 3, and outer tube 2 cup joints each other through flange 4 and bush 5 with inner tube 3, and inner tube 3 is connected with lead screw 11, realizes sliding in outer tube 2 and stretches out and draws back with extension or shrink landing leg main part. Specifically, the lead screw 11 is arranged in the outer tube 2, one end of the lead screw 11 is connected with the pinion 10 through the link shaft 12, the other end of the lead screw 11 is connected with the inner tube 3 through the nut 13, and when the pinion 10 rotates, the lead screw 11 can be driven to rotate, so that the inner tube 3 is driven to realize telescopic motion in the outer tube 2.
When the supporting leg device works, power output by the driving motor 6 is transmitted through the gear set 8 to drive the main gear 9 to rotate, the main gear 9 is connected with the auxiliary gear 10, the auxiliary gear 10 can be driven to rotate, the supporting leg main body can be rotated to a vertical position from an original horizontal position through the rotation of the auxiliary gear 10, at the moment, the auxiliary gear 10 continues to rotate, the inner tube 3 is driven to extend out of the outer tube 2, and therefore the length of the supporting leg is prolonged to adapt to the supporting height of the supporting leg to a motor home. When the landing leg rotates to vertical position, the landing leg is blocked by the locating part, keeps in vertical state, prevents that the landing leg from continuing to rotate, and skew vertical position causes the holding power distortion of landing leg, and the holding power is not enough. When the supporting legs are folded, the supporting legs can be retracted and rotated to the horizontal position for fixing only by reversely rotating the driving motor 6.
Further, the rotating mechanism further comprises a transmission shaft 7, the transmission shaft 7 is connected with a main gear 9, one end of the transmission shaft 7 is a hand-operated end, and when the motor is powered off or a system fails, the supporting legs can be folded manually, namely, the supporting legs can be folded electrically or retracted manually.
For the adaptation at subaerial supporting recreational vehicle that has the slope, be equipped with bulb 14 in the bottom of inner tube 3, footing fixed plate 15 and footing board 16, bulb 14 passes through footing fixed plate 15 activity and sets up in footing board 16, and footing board 16 can be followed certain angle rotation under bulb 14's the regulation to adapt to the bottom surface of different slopes, make the landing leg be in vertical position all the time, in order to guarantee the support intensity of landing leg, and can have certain angle between footing board 16 and the landing leg main part.
The working principle is as follows: the initial condition is landing leg horizontal installation on vehicle chassis, and when on-vehicle fixed locking device was released, the landing leg was under gravity and motor drive, and the landing leg is rotatory to vertical state by the horizontality, rotates to mechanical spacing back, and on the drive power transmission of motor reached lead screw 11, the stroke jacking, and outer tube 2 is stretched out to inner tube 3, realizes supporting the car. During the shrink, the motor reversal, the landing leg is rotatory to the horizontality from vertical state, reaches the spacing back of stopper, and on-vehicle fixed locking device work, outer tube 2 is advanced in the shrink of inner tube 3, accomplishes the shrink.
The utility model discloses compare in current landing leg structure of bending, have following advantage: the utility model discloses an automatic folding, gear drive's of single power source structure has saved the stroke that the tradition landing leg mechanism of bending occupied of bending, has solved the big problem of traditional landing leg occupation space, can satisfy less installation space's operational environment requirement, moreover the utility model discloses whole landing leg closure height reduces, and effective stroke increase is fast, and is efficient, and the strong reliability more can satisfy the demand.
