[0051] Please refer to Figures 1 to 6 , this embodiment provides a mobile storage cabinet, including: a storage cabinet, a transport vehicle, and a lifting device;

[0052] The storage locker 1 includes a cabinet body 12, a partition 13, and a lifting platform 14. The cabinet body 12 is provided on a base 11 and supports a plurality of partitions 13. A first guiding structure 16 is provided on the upper surface of each partition 13. On the same side of each partition 13, there is a pick-up and drop-off opening 15 for the lifting platform 14 to stay. A second guiding structure 17 is provided on the upper surface of the lifting platform 14. The first guiding structure 16 and the second guiding structure 17 are spliced into an oval shape.

[0053] The transporter 2 includes a receiving tray 21, a wheel assembly, and an elastic auxiliary guiding structure 27. The top of the receiving tray 21 has a storage space. The wheel assembly includes a front wheel 22, a front axle 23, a rear wheel 24, and a rear axle 25. The front wheel 22 is provided on both sides of the front axle 23. The front axle 23 is provided on the bottom of the receiving tray 21 through a steering structure 26 and an elastic auxiliary guiding structure 27. The rear wheel 24 is provided on both sides of the rear axle 2. The rear axle 25 is provided on the bottom of the receiving tray 21. Both the front wheel 22 and the rear wheel 24 are adapted to the first guiding structure 16 and the second guiding structure 17. The transporter 2 travels along the first guiding structure 16 and the second guiding structure 17. There are multiple transporters 2, and at least one transporter 2 corresponds to each partition 13.

[0054] The lifting device 3 is connected to the lifting platform 14 and is used to drive the lifting platform 14 to move vertically and reach the pick-up and drop-off opening 15 on one side of each partition 13, so that the first guiding structure 16 and the second guiding structure 17 are aligned.

[0055] The working principle of the mobile storage cabinet is as follows:

[0056] Suppose it is necessary to store a relatively heavy item on a partition at a higher position. First, operate the lifting device through the control system to lower the lifting platform to the bottom. Then, place the item on the transporter located on the lifting platform. After that, the lifting device works again, driving the lifting platform to rise to the pick-up and drop-off opening of the partition at the specified height. At this time, the first guiding structure and the second guiding structure are aligned, and the transporter drives into the partition from the lifting platform, completing the storage process. When encountering uneven tracks or slight offsets, due to the addition of the elastic auxiliary guiding structure, the transporter can travel more precisely along the guiding structure.

[0057] The beneficial effects of the mobile storage cabinet are as follows:

[0058] (1) Through the combined design of the storage locker, the transporter, and the lifting device, even relatively heavy items can be easily transported to higher storage positions. Users do not need to manually carry heavy objects up and down, reducing potential safety hazards.

[0059] (2) The transporter moves on the partition and can play the role of transporting items.

[0060] In this embodiment, the front wheel 22 includes an outer end cover 221, a wheel outer layer 222, an inner end cover 223, and a wheel bearing 224. The outer end cover 221 and the inner end cover 223 are respectively fixed to both sides of the wheel outer layer 222 by bolts. The wheel outer layer 222 is provided on the outer ring of the wheel bearing 224, and the front axle 23 is provided on the inner ring of the wheel bearing 224. Preferably, the inner end cover 223 is designed as two symmetric halves for easy use. The wheel outer layer 222 contacts the first guiding structure 16 (the U-shaped sliding rail on the partition) or the second guiding structure 17 (the U-shaped sliding rail on the lifting platform), responsible for supporting the transporter and its load, and traveling along the U-shaped sliding rail. As an implementation manner, the wheel outer layer 222 is located inside the U-shaped sliding rail. The wheel bearing 224 is located in the empty assembly space formed between the outer end cover 221, the wheel outer layer 222, and the inner end cover 223. The front axle 23 can pass through the inner end cover 223 and be inserted into the inner ring of the wheel bearing 224. The wheel bearing 224 reduces the friction when the wheel rotates, enabling the transporter to move smoothly on the guiding structure, whether traveling straight or turning.

[0061] In this embodiment, the elastic auxiliary guiding structure 27 includes two baffles 272 and two springs 271; the two baffles 272 are provided on the bottom of the receiving tray 21 and are spaced apart along the length direction of the front axle 23. One end of the spring 271 is provided on the baffle 272, and the other end of the spring 271 is provided on the front axle 23. Each end of the front axle corresponds to a spring 271, and one spring 271 corresponds to one baffle 272. During the steering process, the front wheel 22 needs to change direction. Due to the presence of the spring 271, the lateral force generated during steering can be partially absorbed by the spring 271, reducing the impact on other mechanical components and providing additional stability at the same time. The elastic auxiliary guiding structure 27 provides correct guidance for the transporter and, in cooperation with the light spring, realizes the default forward direction of the transporter.

[0062] Please refer to Figure 1 、 Figure 4 and Figure 5 In this embodiment, the storage cabinet 1 includes a base 11, and the base 11 is located on one side of the cabinet body 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 provided inside the base 11, the output shaft of the motor 31 is connected to the chain transmission structure 33 through the gear transmission structure 32. The chain transmission structure 33 is provided on the cabinet body 12, and the chain 331 of the chain transmission structure 33 is connected to 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 to the cabinet body 12 through the first vertical sliding structure.

[0063] When it is necessary to adjust the height of the lifting platform 14, start the motor 31. The motor 31 drives the chain drive structure 33 to work through the gear drive structure 32, causing the chain 331 to start running. Since the chain 331 is connected to the support rod 34, as the chain 331 moves, 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 reach the required height position.

[0064] Please refer to Figure 6 , in this embodiment, the first vertical sliding structure includes a chute 35 located on the cabinet 12. The chute 35 is parallel to the vertical direction of the cabinet 12. One end of the support rod 34 away from the chain 331 is slidably connected to the chute 35. Ensure that the support rod 34 can freely slide up and down in the chute 35, thereby driving the lifting platform 14 to lift and lower smoothly. At the same time, the chute 35 plays a limiting role, corresponding to the highest and lowest positions of the lifting platform 14.

[0065] Please refer to Figure 6 , in this embodiment, the bottom of the lifting platform 14 has a sleeve 141, and the support rod 34 passes through the sleeve 141 to realize the connection and fixation with the lifting platform 14.

[0066] Please refer to Figure 6 , in this embodiment, the lifting device 3 further includes a second vertical sliding structure 36. The lifting platform 14 is connected to the cabinet 12 through the second vertical sliding structure 36. Through the second vertical sliding structure 36, it is ensured that the lifting movement of the lifting platform 14 is more stable and accurate throughout the process.

[0067] Please refer to Figure 6 , in this embodiment, the second vertical sliding structure 36 includes a plurality of vertical rods 361 and a plurality of vertical sliding sleeves 362; the plurality of vertical rods 361 are arranged on the cabinet 12 and are parallel to the vertical direction; the plurality of vertical sliding sleeves 362 are respectively arranged on the sides of the lifting platform 14, and one vertical sliding sleeve 362 corresponds to one vertical rod 361. Preferably, there are four vertical rods 361, and the four vertical rods 361 are respectively in four directions of the lifting platform 14. Due to the arrangement of the plurality of vertical rods 361 and the vertical sliding sleeves 362, the lifting platform 14 rises smoothly along the vertical rods 361 through the vertical sliding sleeves 362, ensuring the stability and accuracy of the lifting platform 14 throughout the rising process.

[0068] Please refer to Figure 5, in this embodiment, the gear transmission structure 32 includes 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 to 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 meshes with the first bevel gear 321, and the first transmission shaft 325 and the second transmission shaft 326 are vertically arranged on 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 meshes with the third bevel gear 323, and the driving shaft 332 and the second transmission shaft 326 are vertically arranged on the horizontal plane.

[0069] When the lifting platform 14 needs to be started, the motor 31 starts to work, and its rotational force is transmitted to the first bevel gear 321 through the first transmission shaft 325. Then, the first bevel gear 321 transmits the rotational force to the second bevel gear 322 meshing with it. Since the two are vertically arranged, the first direction conversion is achieved. Next, the second bevel gear 322 drives the third bevel gear 323 on the same shaft to rotate, and the third bevel gear 323 then transmits the power to the fourth bevel gear 324 meshing with it to complete 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 rise or fall of the lifting platform 14.

[0070] Preferably, there are two chain transmission structures 33. Both ends of the support rod 34 are respectively connected to a chain transmission mechanism. The two chain transmission mechanisms 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 at the top of the cabinet body 12.

[0071] Please refer to Figure 1 and Figure 4 , in this embodiment, the movable storage cabinet further includes 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 cabinet body 12. The hand-crank structure 37 allows the user to manually adjust the position of the lifting platform 14 without electric drive. Specifically, the hand-crank structure 37 can use a handle to drive the third transmission shaft 327 to rotate, so that the fifth bevel gear on the third transmission shaft 327 rotates the fourth transmission shaft 328 through the sixth bevel gear, and the seventh bevel gear on the fourth transmission shaft 328 rotates the second bevel gear, thereby operating the chain transmission structure.

[0072] When manual control of the lifting platform 14 is required, the operator transmits power through the gear pair to the chain drive structure 33 via the hand-cranking structure 37, thereby driving the movement of the chain 331 and causing the support rod 34 and the lifting platform 14 to move up and down. Once the lifting platform 14 reaches the required height position, the locking structure can be activated. The design of the locking structure should ensure that the lifting platform 14 remains fixed even under the action of external forces.

[0073] Preferably, since a large transmission ratio is not used in the transmission, bevel gears are used to achieve vertical transmission, and thrust will occur axially. Therefore, bearings are installed on the corresponding transmission shafts beside the positions where the bevel gears are placed. For example, deep groove ball bearings are installed between the outer wall of the first transmission shaft and the base, and angular contact bearings are installed between the outer wall of the third transmission shaft and the base. Bearings can also be installed between the driving shaft of the chain drive structure and the base.

[0074] In this embodiment, the locking structure can insert one or more retractable pins into the corresponding holes on the cabinet 12 when the lifting platform 14 reaches the predetermined height, thereby preventing the lifting platform 14 from moving further.

[0075] In this embodiment, the hand-cranking structure 37 can utilize the motor as a damper to prevent safety problems caused by faults such as the breakage of the handle of the hand-cranking structure 37, and the transmission ratio between the handle and the motor is 2:1.

[0076] In this embodiment, the main number of teeth used in the gear transmission is 17 and 34, and the main transmission ratios are also 2:1; therefore, the total transmission ratio i of the gear set input by the manual input shaft 总 is 8:1. However, there is no relationship between the number of teeth between the operating handle and the gear, so the vertical distance l from the center axis of the handle grip to the rotation center of the transmission shaft 中心距 = 38 mm is related to the pitch circle diameter d of the sprocket 链轮 = 130 mm, so other methods are used to determine the final transmission ratio i of the manual rod z = 13.7:1. Similarly, when the motor is selected as the motor, the input gear transmission ratio is 4:1. At the same time, according to the particularity of the motor, the angular velocity should be used for calculation. The rotation angle of the motor for one revolution is 360°, it can be calculated that the sprocket rotates 90°, the transmission distance L is 51 mm, and the chain displacement l generated by the unit angle rotation of the motor is 0.1417 mm. The motor 31 can be selected as a three-phase asynchronous motor, model BN-80-B3, with a large enough torque.

[0077] Please refer to Figure 4, in this embodiment, both the first guiding structure 16 and the second guiding structure 17 are U-shaped sliding rails. By operating the lifting device 3, the lifting platform 14 is raised to the height of the target partition 13. Since the first guiding structure 16 and the second guiding structure 17 are aligned, the transport vehicle 2 can smoothly drive into the first guiding structure 16 of the target partition 13 again to complete the storage task. Usually, the volume of the cabinet 12 is larger than that of the lifting platform 14, which means that the length of the first guiding structure 16 will be longer than that of the second guiding structure 17.

[0078] Please refer to Figure 2 , in this embodiment, the item to be transported is placed on the accommodation tray 21 of the transport vehicle 2 to ensure that the item is stably parked in the storage space. The front wheels 22 control the direction through the steering structure 26, so that the transport vehicle 2 can turn and can travel in an oval shape for one circle.

[0079] In this embodiment, the mobile storage cabinet further includes a controller and a battery. The controller is respectively connected to the lifting device 3 and the battery. The controller, as the core control unit of the entire mobile storage cabinet, is responsible for coordinating the work of each component, including receiving user instructions, operating the lifting device 3, planning the travel path of the transport vehicle 2, etc. The controller can automatically execute tasks through a preset program or receive external instructions for manual operation. The battery provides a power source for the system, especially for the motor 31 (used to drive the lifting device 3), the controller, and other components that may require power support.

[0080] Preferably, the controller is a PLC, which can cooperate with a closed-loop control system composed of travel switches. The input control instructions are carried out in the form of buttons.
