[0017] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0018] The embodiment of the utility model includes a door floor plate 14 and an extension mechanism.

[0019] The extension mechanism is arranged on the door floor 14 , and includes a control module 1 , a motor 2 , an extension plate 3 , a transmission screw 4 , a movable tongue plate 7 , a transmission gear mechanism 9 , a mounting seat 10 , a screw nut 11 , a gear motion system 12 and a cover plate 13 .

[0020] Since the placement of the extension mechanism will cause the ground to be raised to a certain height, a mounting groove 15 is provided on the door floor slab 14, and an interface is reserved for the power supply system.

[0021] The mounting seat 10 is installed in the mounting groove 15. The cover plate 13 is installed on the top of the mounting seat 10 to cover the mounting seat 10; the cover plate 13 is flush with the upper surface of the floor plate 14 of the floor door.

[0022] The control module 1 and the motor 2 are both fixedly mounted in the mounting seat 10 , and the control module 1 is connected to the motor 2 .

[0023] The transmission screw rod 4 is rotatably mounted in the mounting seat 10, and the tail of the transmission screw rod 4 is connected to the motor 2 through the transmission gear mechanism 9. The screw nut 11 is mounted on the transmission screw rod 4.

[0024] The movable tongue plate 7 is fixedly connected to the screw nut 11, and the movable tongue plate 7 is slidably mounted on the mounting seat 10 through the gear motion system 12. The gear motion system 12 is divided into two groups, which are respectively arranged on the left and right sides of the movable tongue plate 7. The gear motion system 12 includes a gear 5 and a rack 6. The gear 5 is rotatably mounted on the movable tongue plate 7, and the rack 6 is fixedly mounted on the mounting seat 10. The gear 5 is meshed with the rack 6, and the movable tongue plate 7 is tightly connected to the mounting seat 10 through the engagement of the rack 5 and the rack 6. The movable tongue plate 7 is in a "Z" shape from the cross section, and is extended and retracted by the motor 2 and the gear motion system 12. A reinforcing plate is arranged inside the movable tongue plate 7 to ensure its structural stability and load-bearing capacity.

[0025] The extension plate 3 is slidably mounted on the cover plate 13 , and the extension plate 3 is connected to the movable tongue plate 7 .

[0026] A floor support 8 is fixed between the side surface of the landing door floor 14 and the bottom surface of the mounting seat 10, and the floor support 8 mainly plays the role of supporting the extension mechanism.

[0027] The specific operation process is as follows: the AGV stops at the elevator entrance, and the AGV control system sends an elevator entry request command to the elevator 16 through the network; after receiving the signal from the AGV control system, the elevator 16 opens the door, keeps the normally open state, and feeds back the elevator 16 opening signal to the AGV control system; after the elevator 16 opens the door, the signal is fed back to the control module 1, and the transmission screw 4 is driven to rotate through the motor 2, and the transmission screw 4 drives the movable tongue plate 7 to move forward through the screw nut 11, and the movable tongue plate 7 drives the extension plate 3 to extend out of the wall to overlap the joint between the floor plate and the elevator 16; the length of the extension plate 3 is based on the "Elevator Engineering Construction Quality Acceptance Standard" that "the horizontal distance deviation between the floor door floor plate and the car floor plate is 0-+3mm, and the maximum distance is strictly prohibited to exceed 35mm." The control system of the AGV trolley receives the signal that the extension plate 3 has been extended and sends a driving command to the AGV trolley, and the trolley enters the elevator 16 through the extension plate 3. After the AGV enters the elevator 16, it sends a floor instruction to the elevator 16. After the elevator 16 receives the instruction, the control module 1 controls the retraction of the extension plate 3, closes the elevator door, and reaches the designated floor. After the elevator 16 reaches the designated floor, the elevator door opens and remains normally open. The control module 1 of the extension mechanism of this floor controls the extension plate 3 to be extended, and the elevator door normally open signal is sent to the AGV control system; after the AGV control system receives the arrival at the designated floor, it sends a driving instruction to the AGV trolley, and the AGV trolley drives out of the elevator 16. After the AGV trolley uses the elevator 16, the AGV control system feeds back a signal to the elevator 16, the elevator door closes, and the control module 1 controls the retraction of the extension plate 3 to enter the next cycle.

[0028] In addition, it should be noted that the shapes and names of the parts and components of the specific embodiments described in this specification may be different, and the above content described in this specification is only an example of the structure of the utility model. All equivalent changes or simple changes made based on the structure, features and principles described in the patent concept of the utility model are included in the protection scope of the utility model patent. Technicians in the technical field of the utility model can make various modifications or supplements to the specific embodiments described or replace them in a similar manner, as long as they do not deviate from the structure of the utility model or exceed the scope defined by the claims, they should all fall within the protection scope of the utility model.
