[0024] The following are specific embodiments of the present utility model in combination with the drawings, further describing the technical solutions of the present utility model, but the present utility model is not limited to these embodiments.

[0025] As Figure 1 — Figure 4As shown in the figure, a car bottom structure of a freight elevator of the present utility model includes a car bottom plate 100, a lifting plate 300, a lifting member 200, a moving plate 400 and a driving member 500.

[0026] The lifting plate 300 is movably arranged on the car bottom plate 100, and the lifting plate 300 can be lifted and lowered relative to the car bottom plate 100; the lifting member 200 is arranged between the lifting plate 300 and the car bottom plate 100, and the lifting member 200 can drive the lifting plate 300 to lift and lower relative to the car bottom plate 100; the moving plate 400 is movably arranged on the lifting plate 300, and a driving member 500 for driving the moving plate 400 to move directionally relative to the lifting plate 300 is arranged on the lifting plate 300. When the freight elevator rises to the designated floor, the moving plate 400 is flush with the floor plate 600 of this floor. After that, people can control the lifting member 200 of this car bottom structure to push the lifting plate 300 to rise. Since the moving plate 400 is arranged on the lifting plate 300, in this way, the lifting plate 300 will also drive the moving plate 400 to rise until the lifting plate 300 is flush with the floor plate. After that, people then control the driving member 500 to make the driving member 500 drive the moving plate 400 to move directionally relative to the lifting plate 300, so as to realize the extension of the moving plate 400 from the inside of the freight elevator. In this way, it is convenient for people to take out the goods from the moving plate 400 or place the goods outside on the moving plate 400, that is, when people carry goods, there is no need to enter the inside of the freight elevator, avoiding people carrying goods in a narrow space and facilitating people's operation; when the goods handling is completed, people then operate the driving member 500 to control the moving plate 400 to retract into the inside of the freight elevator. After that, the lifting member 200 is controlled again to control the lifting plate 300 to descend to the initial state until the moving plate 400 is flush with the floor plate.

[0027] The driving member 500 includes an upper motor 510 arranged on the lifting plate 300. An upper lead screw 520 is installed on the upper motor 510. A fixed block 410 is arranged on the side surface of the moving plate 400 facing the lifting plate 300. The upper lead screw 520 passes through the fixed block 410 in a threaded manner. A plurality of guide wheels 420 are arranged on the side surface of the moving plate 400 facing the lifting plate 300. A guide groove (not marked in the figure) for guiding the corresponding guide wheels 420 is arranged on the lifting plate 300. During operation, the upper motor 510 drives the upper lead screw 520 to rotate. Since the upper lead screw 520 passes through the fixed block 410 in a threaded manner, the guide wheels 420 on the moving plate 400 can only move directionally along the corresponding guide groove. In this way, the upper lead screw 520 will push the fixed block 410 and the moving plate 400 to move directionally along the track of the guide groove, so as to realize the extension of the moving plate 400 outside the freight elevator or the retraction of the moving plate 400 into the freight elevator.

[0028] The lifting plate 300 is provided with a blocking block 310. One end of the upper lead screw 520 is movably inserted into the blocking block 310. During operation, the upper lead screw 520 rotates relative to the blocking block 310 to drive the fixed block 410 to move. And when the fixed block 410 abuts against the blocking block 310, the blocking block 310 will limit the further outward movement of the fixed block 410 on the upper lead screw 520, thereby preventing the fixed block 410 from detaching from the upper lead screw 520 and further avoiding the complete separation of the moving plate 400 from the freight elevator. A buffer block 311 for blocking the fixed block 410 is provided on one side of the blocking block 310 facing the upper lead screw 520. Through the arrangement of the buffer block 311, when the fixed block 410 impacts the blocking block 310, the buffer block 311 can effectively buffer the fixed block 410, thereby preventing the fixed block 410 from being damaged.

[0029] The lifting member 200 includes a lower motor 210 provided on the car floor 100 and two commutators 220. A transmission rod 230 is passed through the lower motor 210. Both ends of the transmission rod 230 are respectively inserted into the commutators 220. The two commutators 220 are respectively located at both ends of the lower motor 210. A transmission seat 240 is provided at both ends of each commutator 220. A worm 241 is movably passed through the transmission seat 240. One end of the worm 241 extends out of the top of the transmission seat 240. A lifting disc 242 is provided at the top of the worm 241. A driving rod 250 is provided between each transmission seat 240 and the adjacent commutator 220. One end of the driving rod 250 meshes with the transmission rod 230. The other end of the driving rod 250 is provided with a worm gear (not marked in the figure) that meshes with the adjacent worm 241. Internal bevel gears (not marked in the figure) are provided at both ends of the transmission rod 230. External bevel gears (not marked in the figure) that mesh with the corresponding internal bevel gears (not marked in the figure) are provided at one end of each driving rod 250. A fixed sleeve 243 is provided on one side of each transmission seat 240. The driving rod 250 movably passes through the corresponding fixed sleeve 243. Each worm gear (not marked in the figure) is located within the corresponding fixed sleeve 243. During operation, the lower motor 210 drives the transmission rod 230 to rotate. Since the two ends of the transmission rod 230 and the corresponding driving rods 250 are meshed through the internal bevel gears (not marked in the figure) and the external bevel gears (not marked in the figure), the transmission rod 230 can transfer kinetic energy to the corresponding driving rods 250 through the internal bevel gears (not marked in the figure) and the external bevel gears (not marked in the figure), thereby causing the driving rods 250 to rotate. Since the worm gears (not marked in the figure) on the driving rods 250 mesh with the worms 241 within the corresponding transmission seats 240, in this way, the driving rods 250 can drive the worms 241 to move up and down relative to the transmission seats 240, thereby realizing the rise or fall of the lifting disc 242, that is, realizing the rise or fall of the lifting plate 300.
