[0051] The lifting device 3 is connected with the lifting platform 14, and is used to drive the lifting platform 14 to move in the vertical direction and reach the docking port 15 on one side of each layer plate 13, so that the first guide structure 16 and the second guide structure 17 are aligned.

[0052] The working principle of the movable storage mechanism is as follows:

[0053] Suppose a heavy object needs to be stored on the higher layer plate 13, first control the lifting device 3 to make the lifting platform 14 descend to the bottom, then place the object on the transport vehicle 2 located on the lifting platform 14, and then the lifting device 3 works again to drive the lifting platform 14 to rise to the specified height of the layer plate 13 connection port 15, at this time the first guide structure 16 and the second guide structure 17 are aligned, the transport vehicle 2 enters the layer plate 13 from the lifting platform 14, and the storage process is completed.

[0054] The movable storage mechanism has the following advantages:

[0055] (1) By adopting the combination of the storage rack 1, the transport vehicle 2 and the lifting device 3, even heavy objects can be easily transported to higher storage locations, and users do not need to manually carry heavy objects up and down, reducing safety hazards.

[0056] (2) The transport vehicle 2 moves on the layer plate 13, which can transport objects.

[0057] Please refer to Figures 1 to 3 In this embodiment, the storage rack 1 includes a base 11 located on one side of the frame 12; the lifting device 3 includes a motor 31, a gear transmission structure 32, a chain transmission structure 33 and a support rod 34, the motor 31 is arranged in the base 11, the output shaft of the motor 31 is connected with the chain transmission structure 33 through the gear transmission structure 32, the chain transmission structure 33 is arranged on the frame 12, the chain 331 of the chain transmission structure 33 is connected with the lifting platform 14 through the support rod 34, the lifting platform 14 rises and falls following the rotation of the chain 331, and the end of the support rod 34 away from the chain 331 is slidably connected with the frame 12 through the first vertical sliding structure.

[0058] When the height of the lifting platform 14 needs to be adjusted, the motor 31 is started, the motor 31 drives the chain transmission structure 33 to work through the gear transmission structure 32, so that the chain 331 starts to run. Since the chain 331 is connected with the support rod 34, with the movement of the chain 331, the support rod 34 will rise or fall along the direction guided by the first vertical sliding structure, thereby driving the lifting platform 14 to the desired height position.

[0059] Please refer to Figures 1 to 4 In this embodiment, the first vertical sliding structure includes a sliding groove 35 located on the frame 12, the sliding groove 35 is parallel to the vertical direction of the frame 12, and the end of the support rod 34 away from the chain 331 is slidably connected with the sliding groove 35. Ensure that the support rod 34 can freely slide up and down in the sliding groove 35, thereby stably driving the lifting platform 14 to rise and fall. At the same time, the sliding groove 35 plays a limiting role, corresponding to the highest position and the lowest position of the lifting platform 14.

[0060] Please refer to Figure 4In the embodiment, the bottom of the lifting platform 14 is provided with a sleeve 141, and the supporting rod 34 passes through the sleeve 141 to realize the connection and fixation with the lifting platform 14.

[0061] Please refer to Figure 4 In the embodiment, the lifting device 3 further comprises a second vertical sliding structure 36, and the lifting platform 14 is connected with the frame 12 through the second vertical sliding structure 36. The second vertical sliding structure 36 ensures the lifting movement of the lifting platform 14 to be more stable and accurate during the whole process.

[0062] Please refer to Figure 4 In the embodiment, the second vertical sliding structure 36 comprises a plurality of sliding rods 361 and a plurality of vertical sliding sleeves 362. The plurality of sliding rods 361 are arranged on the frame 12 and parallel to the vertical direction. The plurality of vertical sliding sleeves 362 are respectively arranged on the side edges of the lifting platform 14, and one vertical sliding sleeve 362 corresponds to one sliding rod 361. Preferably, there are four sliding rods 361, and the four sliding rods 361 are respectively arranged at four directions of the lifting platform 14. Due to the arrangement of the plurality of sliding rods 361 and the vertical sliding sleeves 362, the lifting platform 14 stably rises along the sliding rods 361 through the vertical sliding sleeves 362, which ensures the stability and accuracy of the lifting platform 14 during the whole rising process.

[0063] Please refer to Figure 3 In the embodiment, the gear transmission structure 32 comprises a first bevel gear 321, a second bevel gear 322, a third bevel gear 323 and a fourth bevel gear 324. The first bevel gear 321 is arranged on the base 11 through a first transmission shaft 325, and the first transmission shaft 325 is connected with the motor 31. The second bevel gear 322 and the third bevel gear 323 are arranged on the base 11 through a second transmission shaft 326, the second bevel gear 322 is engaged with the first bevel gear 321, and the first transmission shaft 325 and the second transmission shaft 326 are arranged vertically in the horizontal plane. The driving shaft 332 of the chain transmission structure 33 is arranged on the base 11, the fourth bevel gear 324 is arranged on the driving shaft 332, the fourth bevel gear 324 is engaged with the third bevel gear 323, and the driving shaft 332 and the second transmission shaft 326 are arranged vertically in the horizontal plane.

[0064] When the lifting platform 14 needs to be activated, the motor 31 starts to work, and its rotating force is transmitted to the first bevel gear 321 through the first transmission shaft 325. Then, the first bevel gear 321 transmits the rotating force to the second bevel gear 322 engaged therewith, and since the two gears are arranged vertically, the first direction conversion is realized. Next, the second bevel gear 322 drives the third bevel gear 323 on the same shaft to rotate, and the third bevel gear 323 transmits the power to the fourth bevel gear 324 engaged therewith, completing the second direction conversion. Finally, the fourth bevel gear 324 drives the driving shaft 332 of the chain transmission structure 33 to rotate, and the chain 331 moves accordingly, realizing the lifting or lowering of the lifting platform 14.

[0065] Preferably, the chain transmission structure 33 has two, and the two ends of the support rod 34 are connected to one chain transmission structure respectively, and the two chain transmission structures share the driving shaft 332 and the driven shaft. The driving shaft 332 is located on the base 11, and the driven shaft is located on the top of the frame 12.

[0066] Please refer to Figure 1 and Figure 2 In the embodiment, the movable storage mechanism further comprises a hand crank structure 37 and a locking structure. The hand crank structure 37 is arranged on the base 11 and is in transmission connection with the gear transmission structure 32, and the locking structure is used to lock the lifting platform 14 on the frame 12. The hand crank structure 37 allows the user to manually adjust the position of the lifting platform 14 without power driving. Specifically, the hand crank structure 37 can use a handle to rotate the third transmission shaft through the transmission of the fifth bevel gear and the sixth bevel gear, and the third transmission shaft (which can be the first transmission shaft 325) drives the second bevel gear to rotate through the seventh bevel gear, and then drives the chain transmission structure to work.

[0067] When the lifting platform 14 needs to be manually controlled, the operator drives the power to the chain transmission structure 33 through the gear pair by the hand crank structure 37, and then drives the chain 331 to move, so that the support rod 34 and the lifting platform 14 move up and down. Once the lifting platform 14 reaches the desired height position, the locking structure can be activated. The design of the locking structure should ensure that the fixed state of the lifting platform 14 can be maintained even under external force.

[0068] In the embodiment, one or more retractable pins can be used to prevent the lifting platform 14 from moving further when the lifting platform 14 reaches the predetermined height by being inserted into the corresponding hole on the frame 12.

[0069] In the embodiment, the hand crank structure 37 can use the motor as a damper to prevent safety problems caused by the breakage of the handle of the hand crank structure 37 and the like, and the transmission ratio between the handle and the motor is 2:1.

[0070] Please refer to Figure 2In this embodiment, the first guide structure 16 and the second guide structure 17 are both U-shaped rails. The lifting platform 14 is raised to the height of the target layer 13 by operating the lifting device 3. Since the first guide structure 16 and the second guide structure 17 are aligned, the transport vehicle 2 can smoothly enter the first guide structure 16 of the target layer 13 from the lifting platform 14 to complete the storage task. Generally, the volume of the frame 12 is larger than that of the lifting platform 14, which means that the length of the first guide structure 16 is longer than that of the second guide structure 17.

[0071] Please refer to Figure 5 In this embodiment, the transport vehicle 2 includes a tray 21 and a wheeled assembly; the tray 21 has empty spaces on the top as storage spaces; the wheeled assembly includes a front axle 23 and a rear axle 25, the front axle 23 is provided with front wheels 22 on both sides, the front axle 23 is arranged on the bottom of the tray 21 through a steering structure 26, the rear axle 25 is provided with rear wheels 24 on both sides, the rear axle 25 is arranged on the bottom of the tray 21, and the front wheels 22 and the rear wheels 24 are adapted to the first guide structure 16 and the second guide structure 17. The articles to be carried can be placed on the tray 21 of the transport vehicle 2, ensuring that the articles are stably parked in the storage spaces. The front wheels 22 are controlled in direction by the steering structure 26, so that the transport vehicle 2 can turn and drive along the waist circle.

[0072] In this embodiment, the transport vehicle 2 further includes a controller and a battery, and the controller is connected with the lifting device 3 and the battery. The controller serves as the core control unit of the entire movable storage mechanism, responsible for coordinating the work of various components, including accepting user instructions, operating the lifting device 3, planning the driving path of the transport vehicle 2, etc. The controller can automatically execute tasks through pre-set programs, or can receive external instructions for manual operation. The battery provides power source for the system, especially for the motor 31 (used to drive the lifting device 3), the controller and other components that may need power support.

[0073] Preferably, the controller is a PLC, which can form a closed-loop control system with a limit switch, and input control instructions through the button, and the contactor as a switch to control the motor forward and reverse, and the limit switch as a sensor, and the entire control scheme is realized by the internal logic control of the PLC.
