Therefore, when the motor 54 drives the lead screw 51 to rotate, the lead screw 51 can rotate freely in the fixed seat 53, and at the same time, the lead screw 51 can also rotate in the nut 52, and as the lead screw 51 is connected with the nut 52 through the threads, the nut 52 and the fixed seat 53 are far away or close to each other, so that the first mounting plate 61 and the second mounting plate 62 are far away or close to each other.

The motor 54 transmits the rotation motion to the lead screw 51 through the output gear 56 and the transmission gear 57, and due to the fixation of the nut 52, the nut 52 and the fixed seat 53 are mutually far away or close by the positive rotation and the negative rotation of the motor 54, and then the first mounting plate 61 and the second mounting plate 62 are mutually far away or close, and finally the jacking and descending actions are realized.
In the embodiment of the present invention, since the fixing seat 53 and the nut 52 are not fixed in the axial direction of the screw 51, and the two ends of the inclined slideway 3 are respectively provided with a section of horizontal groove 32, the horizontal groove 32 plays a role that the screw 51 is not acted by load before and after jacking. When the cam 41 rolls in the horizontal groove 32, the entire drive mechanism 5 floats on the movable slide 7. As shown in fig. 2, when the fixed seat 53 and the screw 52 perform the axial moving away action of the screw 51, the jacking tray 2 will be jacked up, the cam 41 will be initially located on the horizontal groove 32 at the bottom of the inclined slideway 3, and one of the fixed seat 53 and the screw 52 will receive the axial force of the screw 51, which is the force of the cam 41 acting on the boundary between the inclined groove 31 and the horizontal groove 32 when the cam 41 is about to climb. However, since the driving mechanism 5 is entirely floated and adaptive reaction is performed, the cam 41 which is first subjected to the axial force does not continue to move axially, because the balance is not achieved, and the cam 41 which is not subjected to the axial force continues to move away until all the cams 41 finish moving the horizontal groove 32, and then climbing is about to start. Moreover, when the two ends of the screw 51 are stressed uniformly, the inclined slideway 3 corresponding to the fixing seat 53 and the inclined slideway 3 of the screw 52 move horizontally at the same time, so that the two ends of the jacking tray 2 are synchronously jacked, and the same principle of falling is also applied. Therefore, the jacking mechanism provided by the embodiment of the invention has the advantage of simple structure, can be realized by adopting the lead screw 51 in the same rotating direction, is very convenient to install, does not need to consider the problem of the precision of axial installation too much, and can be axially self-adaptive as the whole mechanism, so that the service life of the jacking mechanism is prolonged.
As shown in fig. 8, an embodiment of the present invention further provides an automatic guided vehicle 100, which includes the jacking mechanism 10 described in any of the above embodiments, the jacking mechanism 10 is installed inside the automatic guided vehicle 100, and the jacking tray 2 is jacked up to complete the jacking and dropping actions of the shelf.
Therefore, when the driving mechanism drives the oblique slideways to move away from or close to each other, the sliding assembly can slide from one end of the oblique slideway to the other end of the oblique slideway, so that the jacking tray is driven to ascend or descend relative to the fixed frame. The jacking mechanism provided by the embodiment of the invention can improve the stability of the jacking mechanism during frequent movement, prolong the service life of the jacking mechanism and reduce the machining precision, thereby saving the machining cost and reducing the installation difficulty of the mechanism.
The above-described embodiments should not be construed as limiting the scope of the invention. Those skilled in the art will appreciate that various modifications, combinations, sub-combinations, and substitutions can occur, depending on design requirements and other factors.
