Specific embodiments

[0042] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0043] Through the investigation and analysis of the existing technology, it is found that the following problems still exist in the current technical development of cold chain storage and logistics cabinets:

[0044] On the one hand, there are deficiencies in temperature control and the diversity of goods storage: Most cold-chain storage logistics cabinets adopt the method of overall temperature control for a single container, with a single type of goods that can be stored, resulting in low distribution efficiency. Even though some patents have proposed a multi-container structure, such as the patent with the publication number CN118701521A, which proposed an ultra-low temperature cold-chain transportation device that separates fresh produce and dishes and stores them in two different cargo boxes, its structure is still relatively complex, and the types of goods that can be stored are still limited.

[0045] On the other hand, the goods retrieval method is backward: Currently, most cold-chain storage logistics cabinets still use the method of manually opening the door to retrieve goods. Each time goods are retrieved, they will come into contact with the external environment, making it difficult to constantly maintain the temperature inside the cabinet, and easily causing the stored goods to deteriorate and be damaged. In addition, when there are a large number of goods, they cannot be stored separately by category, further increasing the inconvenience of retrieving goods.

[0046] In summary, the existing cold-chain storage logistics cabinets have obvious deficiencies in aspects such as the diversity of goods storage, temperature control accuracy, and convenience of goods retrieval. It is urgent to innovate the design of cold-chain storage logistics cabinets and their goods retrieval systems, and propose a multi-temperature cold-chain storage logistics cabinet and an intelligent goods retrieval system to improve distribution efficiency.

[0047] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0048] Referring to Figures 1 to 7 As shown, an embodiment of the present invention provides a multi-temperature cold-chain storage logistics cabinet, including a cabinet body 1. The cabinet body 1 has a cubic structure, and its outer shell is usually made of metal or composite materials, having high strength and corrosion resistance. An insulation layer is provided inside the outer shell, and heat insulation materials such as high-density polyurethane foam, polystyrene, or glass wool are filled in the insulation layer, which can effectively isolate the external temperature and maintain a low-temperature environment inside the box. A refrigeration external unit 5 is connected to one side of the cabinet body 1 (specifically, the rear side of the cabinet body 1 in this embodiment) to provide a cold source for the cabinet body 1. A temperature control system and a monitoring system are equipped inside the cabinet body 1, specifically including a constant temperature device and multiple temperature sensors. An intelligent control terminal 2 is connected to one side of the cabinet body 1. The constant temperature device and the temperature sensors are electrically connected to the intelligent control terminal 2, and the data inside the box can be monitored according to transportation requirements, and the temperature inside the box can be automatically adjusted. A plurality of independent compartment doors 3 are opened on the front side of the cabinet body 1, and a display 4 is equipped. The compartment doors 3 are hinged or slidably connected to the outer shell of the cabinet body 1 in a push-pull manner, and there is at least one sealing gasket between the two to ensure its sealing performance. The display 4 is used to display the goods storage information inside the cabinet body 1 in real time. The personnel for storing and retrieving goods can select the goods to be stored or retrieved through the goods retrieval interface in the display 4 to achieve visualization.

[0049] In order to meet the storage requirements of goods with multiple varieties and multiple temperature zones, three layers of storage space are designed inside the cabinet body 1. Four storage boxes 6 can be placed on each layer of storage space, and each storage box 6 can realize the function of independent refrigeration and temperature control. Goods of different categories can be stored in different storage boxes 6 according to storage requirements to achieve differential temperature control and solve the problem of multi-goods multi-temperature storage.

[0050] Specifically, as Figure 3 shown, the inside of the cabinet body 1 is divided into three layers, separated by partition boards. Each layer includes a rotary translation mechanism 7, a refrigerator 9, and multiple storage boxes 6. Correspondingly, three cabinet doors 3 are arranged in sequence from top to bottom on the front side of the cabinet body 1, and each cabinet door 3 corresponds to one layer of storage boxes 6. The partition board divides the internal space of the cabinet body 1 into three independent temperature control zones, and a refrigerator 9 is arranged in each temperature control zone. The refrigerator 9 on each layer is used for overall refrigeration of this layer. Thus, the cabinet body 1 is divided into three independent storage spaces to realize the storage function of multiple varieties of goods.

[0051] It should be understood that in practical applications, the cabinet body 1 can be divided into multiple layers by partition boards according to needs, such as 4 layers, 5 layers, etc. Multiple independently temperature-controlled storage boxes 6 can be arranged on each layer, such as 4, 8, or more.

[0052] In a specific embodiment, 4 storage boxes 6 are arranged on each layer of the cabinet body 1. The 4 storage boxes 6 move their positions through the rotary translation mechanism 7 and then move to the cabinet door 3 of this layer in sequence to realize the storage of goods.

[0053] As Figure 7 shown, annular tracks are respectively opened on the top surface and the bottom surface of the partition board. Guide wheels 604 are respectively connected to the center of the top and the center of the bottom of the storage box 6. The upper and lower guide wheels 604 are respectively connected in a sliding rail manner to the tracks of the upper and lower partition boards, enabling the storage box 6 to freely slide along the track between the upper and lower partition boards.

[0054] As Figure 7As shown in the figure, the rotary translation mechanism 7 includes: four limit axle seats 707 respectively fixed on the upper surface and the lower surface of the lower partition board. The four limit axle seats 707 on the upper layer are distributed in a square array, and the four limit axle seats 707 on the lower layer correspond to the four limit axle seats 707 on the upper layer in pairs. A smooth axle 704 is rotatably installed between the upper and lower limit axle seats 707 with corresponding positions. Both ends of the smooth axle 704 are rotatably matched with the limit axle seats 707 through limit bearings. A bearing gear 706 is fixed at the bottom of one of the smooth axles 704, and this bearing gear 706 meshes with the main gear on the output shaft of the second driving motor 705, being in transmission cooperation with the second driving motor 705. The second driving motor 705 is fixedly installed above the partition board. Rotating gears 703 are fixed at the middle positions of the four smooth axles 704 at the same height. The rotating gears 703 are externally chain-driven to connect with a transmission chain 702, and the outside of the transmission chain 702 is connected with each cargo box 6 through a connecting piece 701. When the second driving motor 705 operates, the rotation torque is transmitted to one of the smooth axles 704 through the bearing gear 706. At this time, the smooth axle 704 rotates, drives the transmission chain 702 to rotate through the rotating gear 703 fixed on this smooth axle 704, and further drives the cargo box 6 to move along the track, realizing the planar rotary motion of the cargo box 6. The cargo box 6 corresponding to the goods can be moved to the pick-up port through the rotary translation mechanism 7, which can effectively solve the problems of heat loss of the cargo box 6 and low pick-up efficiency.

[0055] As Figures 4 to 6 shown, the cargo box 6 includes a box body 601. A cargo box door 602 is hinged on the front side of the box body 601. A first driving motor 605 is fixed on the box body 601 on the side where the cargo box door 602 is hinged to the box body 601. The first driving motor 605 is in transmission connection with the cargo box door 602 and is used to drive the cargo box door 602 to rotate, realizing the automatic opening and closing of the cargo box door 602. As Figure 5 shown, in a specific embodiment, a driving bevel gear is fixedly connected to the output shaft of the first driving motor 605, and a driven bevel gear is fixed on the end face of the hinge shaft of the cargo box door 602. This driven bevel gear meshes with the driving bevel gear to jointly form a transmission gear set 606. The first driving motor 605 is electrically connected to the intelligent control terminal 2 and is controlled by the intelligent control terminal 2 to operate. When the first driving motor 605 rotates forward, it drives the cargo box door 602 to rotate forward around its hinge shaft, completing the opening of the cargo box door 602. When the first driving motor 605 rotates in the reverse direction, it drives the cargo box door 602 to rotate in the reverse direction around its hinge shaft, completing the closing of the cargo box door 602.

[0056] As Figure 4 and Figure 6As shown in the figure, in order to realize the independent temperature control function of a single cargo box 6, an independent temperature control unit is respectively provided on each cargo box 6. The temperature control unit includes an intake fan 603 installed on one side of the cargo box 6 and a temperature regulator 607 installed inside the cargo box 6. The cold air in this layer is inhaled into the interior of the cargo box 6 through the intake fan 603, and the temperature is regulated by the temperature regulator 607 to realize the independent temperature control of a single cargo box 6.

[0057] Referring to Figures 8 to 10 As shown in the figure, the embodiment of the present invention further provides an intelligent goods picking system, based on the multi-temperature cold chain storage and logistics cabinet described in the above embodiment. The intelligent goods picking system includes an interface management system, a background management system, and a temperature management system.

[0058] The interface management system realizes human-computer interaction through a display 4. The interaction interface includes an authorization code input interface, a goods type selection interface, a pick-up code input interface, and a hatch 3 opening and closing inspection interface. The above interfaces are used to realize the efficient and real-time human-computer interaction function.

[0059] The background management system includes a goods management module, a system log module, and an equipment monitoring module. Among them, the goods management module is responsible for processing goods information; the system log module is responsible for recording the operation status of the cold chain cabinet; the equipment monitoring module is responsible for real-time monitoring of each module of the cold chain cabinet. The cooperation of the above modules enables the background management personnel to more conveniently conduct online real-time monitoring and goods storage management of the cold chain storage and logistics cabinet.

[0060] The temperature management system includes a cold chain cabinet temperature adjustment module, a cargo box 6 temperature adjustment module, and a temperature monitoring module. First, the whole cabinet is refrigerated and temperature-controlled through the cold chain cabinet temperature adjustment module. Secondly, the cargo box 6 temperature adjustment module adjusts the internal temperature of the cargo box 6 to the optimal storage temperature of the goods to realize the intelligent temperature control storage function of different goods; finally, the temperature detection module conducts real-time temperature monitoring of the whole cabinet to maintain the temperature inside the cabinet body 1 and the cargo box 6, solving the problem of easy temperature loss of goods during the logistics process.

[0061] The multi-temperature cold chain storage and logistics cabinet equipped with the intelligent goods picking system of this embodiment specifically includes a goods storage process and a goods picking process when storing goods.

[0062] Specifically, the goods storage process includes:

[0063] S11.

[0066] S14. Receive the storage temperature instruction, and adjust the corresponding cargo box 6 to the set temperature according to the storage temperature instruction. Specifically, the temperature management system adjusts the temperature of the cargo box 6 to the preset temperature, or automatically adjusts it to the optimal storage temperature corresponding to the type of goods to be stored selected by the merchant, where the optimal storage temperature is preset in the temperature management system in advance.

[0067] S14. The merchant confirms through the display 4 that the cargo box door 602 and the warehouse door 3 are correctly closed.

[0068] The goods picking process includes:

[0069] S21. Receive the picking instruction, where the picking instruction includes the user picking code, the goods location information, and the goods type information to be picked. After the user inputs the picking code, the background management system locates the corresponding cargo box 6 through the input picking code.

[0070] S22. Select the located cargo box 6 according to the picking instruction and rotate it to the picking opening, and open the cargo box door 602. Specifically, according to the received picking instruction, the background management system rotates and translates the located cargo box 6 to the picking opening on the corresponding layer through the cargo box 6 rotation and translation mechanism 7, and the warehouse door 3 and the cargo box door 602 are automatically opened, and the user takes out the goods in the cargo box 6.

[0071] S23. After receiving the door closing instruction, the cargo box door 602 automatically closes, and the cargo box 6 returns to its original position.
