[0023] like Figures 1-7 The mobile trolley shown includes a base 1, with a through hole in the center of the base 1. A lifting frame 2 is connected to the through hole via a lifting assembly. A telescopic plate 5 is connected to the top of the lifting frame 2 via a telescopic assembly. A support plate 11 is connected to the top of the telescopic plate 5. First guide rails 4 are provided at the front and rear of the base 1. A translation assembly is provided on the base 1.

[0024] The lifting assembly includes a lifting motor 22, which is located at the bottom of the base 1. One or more second guide rails 21 are provided on the lifting frame 2. A guide block is provided on the through hole of the base 1 to cooperate with the second guide rail 21. A second rack 3 parallel to the second guide rail 21 is provided on the lifting frame 2. The second rack 3 meshes with the gear connected to the lifting motor 22. Under the drive of the lifting motor 22, the lifting frame 2 is driven to move up and down along the second guide rail 21.

[0025] The telescopic assembly includes a telescopic motor 23, which is connected to the top of the lifting frame 2. A first rack 7 is provided at the bottom of the telescopic plate 5. A gear set 24 consisting of multiple gears is arranged on the top of the lifting frame 2 corresponding to the first rack 7. The gear set 24 meshes with the transmission gear connected to the telescopic motor 23. Driven by the telescopic motor 23, the gear set 24 drives the telescopic plate 5 to move back and forth along the first rack 7.

[0026] The telescopic plate 5 has an I-shaped groove structure on both sides. Inner pulley sets 8 are arranged in the inward-facing grooves of the I-shaped grooves, and the inner pulley sets 8 are connected to the top of the lifting frame 2. Outer pulley sets 9 are arranged in the outward-facing grooves of the I-shaped grooves, and the outer pulley sets 9 are connected to a long strip-shaped connecting frame 10. The connecting frames 10 on both sides are connected to the bottom of the support plate 11. The inner pulley sets 8 reduce the frictional force of the telescopic plate 5 during movement, and the outer pulley sets 9 reduce the frictional force of the support plate 11 during back-and-forth movement.

[0027] The telescopic plate 5 is equipped with two parallel belts, a first belt 12 and a second belt 16, positioned on either side of the first rack 7. The front end of the telescopic plate 5 is connected to a first pulley 14, through which the first belt 12 passes. One end of the first belt 12 is connected to the bottom of the support plate 11 via a first belt connecting plate 13, and the other end is connected to the top of the lifting frame 2. The rear end of the telescopic plate 5 is connected to a second pulley 17, through which the second belt 16 passes. One end of the second belt 16 is connected to the bottom of the support plate 11 via a second belt connecting plate 15, and the other end is connected to the top of the lifting frame 2. During the forward and backward movement of the telescopic plate 5, either the first belt 12 or the second belt 16 pulls the support plate 11 to move horizontally, achieving a two-stage extension of the moving trolley.

[0028] Side plates 6 are provided on both sides of the pallet 11. The side plates 6 are connected to the lifting frame 2. The height of the side plates 6 is higher than that of the pallet 11, and the distance between the two side plates 6 is greater than the width of the storage box. On the one hand, the storage box can be limited to prevent the moving trolley from sliding out during the translation process. On the other hand, the side plates 6 play a protective role to prevent debris from falling under the pallet 11 and causing the connecting structures under the pallet 11 to jam.

[0029] The translation assembly includes a translation motor 20, which is connected to a base 1. A third pulley 19 is mounted on the base 1 and connected to the translation motor 20. A pressure roller 18 is mounted on each side of the third pulley 19. Figure 7 As shown, the moving trolley is clamped on the vertical travel trolley 25. The first guide rail 4 is matched and connected to the slide groove on the vertical travel trolley 25. The translation belt 26 passes through the pressure roller 18 and the third pulley 19. The two ends of the translation belt 26 are fixed to the two ends of the vertical travel trolley 25. The translation motor 20 rotates to make the third pulley 19 rotate, which drives the moving trolley to move along the translation belt 26.

[0030] When the vertical trolley 25 moves to the height of the corresponding storage box, the telescopic plate 5 and the pallet 11 extend step by step under the drive of the telescopic motor 23 to support the bottom of the storage box. The lifting frame 2 rises under the drive of the lifting motor 22 and lifts the storage box. The telescopic plate 5 and the pallet 11 retract and move the storage box onto the vertical trolley 25. Then, under the drive of the translation motor 20, the storage box is lowered to a suitable position on the vertical trolley 25, so as to realize the intelligent cabinet's precise material retrieval from each storage box.
