Description

Technical Field

[0001] The present application relates to the field of logistics technology, and in particular to a multi-temperature zone carriage with adjustable space and a loading method thereof. Background Art

[0002] The contents of this section merely provide background information related to the present application and may not constitute prior art.

[0003] In the field of modern logistics, with the increasing requirements for food preservation and material storage temperature control, traditional single temperature control carriages can no longer meet the storage needs of diversified goods. For this reason, it is particularly important to develop multi-temperature zone carriages that can adapt to different temperature requirements. In the prior art, the patent with publication number CN112265491A proposes a space-adjustable multi-temperature zone carriage based on semiconductor refrigeration technology, which realizes the refined management of the temperature environment in the carriage and the optimization of space utilization.

[0004] The core concept of the carriage in this patent is to use the semiconductor refrigeration devices integrated on the insulation boards set in the temperature zones. These devices can work independently according to the actual demand of the cargo heat load and the changes in the cargo position, so as to achieve precise control of the temperature of different areas in the carriage. The carriage is carefully divided into high temperature zone, medium temperature zone and low temperature zone. Such a zoning design can accurately meet the differentiated storage temperature requirements of various foods and materials, and effectively ensure the quality and safety of the goods. In addition, in terms of picking up goods, the side door design of the carriage matches the side doors of each temperature zone, which is convenient for operators to take out goods from the designated temperature zone as needed, improving work efficiency.

[0005] However, although this patent has made significant progress in the design of multi-temperature zone carriages, there are still certain limitations. Specifically, the design of its side doors does not fully adapt to the changes in the movement of the insulation panels. In actual operation, when the insulation panels move a large range, multiple temperature zones may open their doors at the same time. This will lead to unnecessary heat exchange when some temperature zones do not need to open their doors for cargo loading and unloading, which will in turn cause an increase in cooling loss and affect the energy efficiency and thermal insulation performance of the carriage. Therefore, how to further reduce cooling loss and improve overall energy efficiency while maintaining the adjustability of the multi-temperature zone carriage space has become a problem that needs to be solved urgently. Summary of the invention

[0006] In order to solve the above technical problems, the purpose of this application is to provide a multi-temperature zone carriage with adjustable space and a loading method thereof, which divides the carriage into multiple temperature zones by setting multiple partitions, and sets sliding doors on the partitions, so that the staff can load and unload the goods in the corresponding temperature zones from the sliding door at the rear of the carriage as needed.

A refrigeration device is arranged in the cold storage area to provide cold air to the cold conduction area. The cold conduction area is connected with the loading area through multiple air holes.

[0016] Furthermore, a plurality of cooling fans are provided in the cooling zone, and the cooling fans transport low-temperature air in the cooling zone to the loading zone to adjust the temperature in the loading zone.

[0017] Furthermore, it also includes a pulley and a slide rail, the pulley is rotatably connected to the plate body, the slide rail is arranged at the bottom of the loading area, and the plate body slides along the slide rail through the pulley.

[0018] In a second aspect, the present invention provides a carriage loading method, which is applied to the multi-temperature zone carriage of the first aspect, and the method comprises:

[0019] According to the quantity and type of goods counted, the occupied space of the goods in each temperature zone is calculated by a loading calculation model; wherein the loading calculation model includes a database and a greedy algorithm model, the database contains the size data and temperature requirement data of each type of goods, the greedy algorithm model uses the quantity and type of goods as input parameters, the size of the compartment and the delivery sequence as constraints, and uses a greedy algorithm to calculate the occupied space of the goods in each temperature zone according to the size and temperature requirement corresponding to each goods;

[0037] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0038] Example 1

[0039] like Figure 1 As shown, a multi-temperature zone compartment with adjustable space is proposed in an embodiment of the present application, comprising:

[0040] The inner wall of the compartment 1 is made of insulation material such as polystyrene foam (EPS) or polyurethane foam (PUR), and a slide rail is provided on the inner wall of the compartment 1 to guide the movement of the partition 3. A sliding door 2 is provided on the side wall of the compartment 1 away from the front of the vehicle to facilitate the staff to load and unload the goods from the rear of the compartment.

[0041] A refrigeration device is arranged in the compartment 1 and is used for cooling the interior of the compartment 1; wherein the refrigeration device adopts a cold storage plate for cooling, and the use of the cold storage plate can effectively reduce the space occupied by the refrigeration device itself, thereby increasing the loading space in the compartment 1 accordingly.

[0042] Multiple partition plates 3, each of which is arranged in the compartment 1 to divide the compartment 1 into multiple different temperature zones, and a temperature sensor is provided in each temperature zone; each partition plate 3 is slidably connected to the inner wall of the compartment 1 along a slide rail, and each partition plate 3 includes a plate body 31, a motor 33 arranged on the plate body 31, a gear 5 connected to the output shaft of the motor 33, and a rack 4 arranged on the side wall of the plate body 31; the gear 5 is meshed with the rack 4, and the motor 33 drives the gear 5 to drive the plate body 31 to slide in the compartment 1.

[0043] Specifically, after the motor 33 is started, the motor 33 drives the gear 5 to rotate, and the gear 5 meshes with the rack 4, and the partition plate 3 slides along the slide rail in the car body 1 with the help of its reaction force. This design allows the position of the partition plate 3 to be flexibly adjusted as needed, thereby creating temperature zones of different sizes. A temperature sensor is installed in each temperature zone for real-time monitoring and feedback of temperature information to ensure that each zone can be kept within the set temperature range. In order to facilitate loading and unloading, a door opening and a sliding door 32 adapted to the door opening are provided on the plate body 31, and the sliding door 32 is slidably connected to the plate body 31, and the sliding door 32 abuts against the plate body 31. In other words, when a certain temperature zone needs to be loaded and unloaded, no matter how the partition plate 3 moves, it is only necessary to open the corresponding sliding door 32 to load and unload. This avoids the situation in the prior art where the side door is opened, resulting in multiple temperature zones being opened at the same time. The loss of cooling capacity is reduced, and the energy efficiency and thermal insulation performance of the car body are guaranteed.

[0044] Among them, the partition plate 3 is slidably connected to the inner wall of the car body 1 along the slide rail, which is mainly achieved through pulleys and slide rails. The pulley is rotatably connected to the car body 1, and the slide rail is set at the bottom of the loading area 12. The car body 1 slides along the slide rail through the pulley.

[0045] Furthermore, it also includes a transmission shaft 37, a worm wheel 36 and a worm 35 meshing with the worm wheel 36, the worm 35 is fixedly connected to the motor 33, the worm wheel 36 is sleeved on the transmission shaft 37, the transmission shaft 37 is rotationally connected to the plate body 31, and the end of the transmission shaft 37 away from the worm wheel 36 is fixedly connected to the gear 5.

[0046] Among them, the worm gear 36 and worm 35 mechanism has a natural self-locking characteristic - that is, when the worm 35 stops rotating, due to the friction between the tooth surfaces of the worm gear 36 and the tooth surfaces of the worm 35, the worm gear 36 is difficult to be driven in the reverse direction, thereby achieving good fixation of the partition plate 3. Compared with the self-locking ability of the motor 33 itself (usually relying on electromagnetic force or mechanical friction), the self-locking performance of the worm gear 36 and worm 35 is more superior. The self-locking of the motor 33 is often limited by multiple factors such as design, materials, and working environment temperature, and may fail under low temperature conditions. The self-locking of the worm gear 36 and worm 35 mainly depends on its geometric structure and the physical friction between the materials. This friction can maintain the self-locking effect of the partition plate 3 even under high temperature or heavy load conditions, thereby ensuring the accuracy of the position movement of the partition plate 3.

[0047] Furthermore, it also includes a universal joint 34, through which the motor 33 is fixedly connected to the worm 35. The setting of the universal joint 34 is intended to ensure an effective and reasonable connection between the motor 33 and the worm 35, while avoiding unnecessary obstacles to the loading and unloading of goods. Specifically, if the output shaft of the motor 33 is directly connected to the worm 35, due to the physical size and layout limitations of the motor 33 and the worm 35, the connection part may appear too prominent, which not only occupies additional space, but may also interfere with the goods in actual operation, thereby affecting the smooth loading and unloading of the goods. In addition, considering that the worm wheel 36 and worm 35 assembly is installed at the edge of the plate body 31, close to the side wall of the compartment 1, this layout further limits the direct installation of the motor 33. Due to the relatively large size of the motor 33, if an attempt is made to directly connect the motor 33 to the worm 35, not only will there be a problem of insufficient installation space, but the mechanical performance may also be reduced or maintenance may be difficult due to improper position. Therefore, in this embodiment, the motor 33 is fixedly connected to the worm 35 via a universal joint 34, so that a certain angle is allowed between the motor 33 and the worm 35, thereby solving the problem of spatial layout and ensuring the stability and reliability of the entire transmission system.

[0048] Furthermore, the interior of the compartment 1 is designed to include a cold storage area 11, a loading area 12, and a cold conduction area 13 located at the top of the compartment 1. The cold storage area 11 is arranged at the front of the compartment 1, and has a built-in cold storage plate for storing cold energy. The cold storage area 11 and the loading area 12 are located below the cold conduction area 13, and the cold conduction area 13 is connected to the cold storage area 11, forming a bridge for cold energy conduction. In the cold storage area 11, a refrigeration device is installed to generate cold air, which is then introduced into the cold conduction area 13. The cold conduction area 13 is connected to the loading area 12 through a plurality of air holes, thereby realizing the delivery of cold energy to the loading area 12.

[0049] In addition, the cooling zone 13 not only serves as a medium for cold transfer, but also has multiple cooling fans 6 built in. These cooling fans 6 rotate to blow low-temperature air in the cooling zone 13 into the loading zone 12, thereby adjusting the temperature of the loading zone 12.

[0050] It is worth noting that the rotation direction and speed of the cooling fan 6 can be controlled. By adjusting these parameters, the air circulation path and cold conduction efficiency inside the compartment 1 can be accurately controlled. This design not only optimizes the temperature distribution inside the compartment 1, but also improves the utilization efficiency of cold energy, ensures that the items in the loading area 12 can be stored at a suitable temperature, and achieves energy saving and high efficiency.

[0051] In an embodiment of the present invention, a slide rail is provided on the inner wall of the compartment 1 to guide the partition plate 3 on which the motor 33 is installed to slide along the slide rail, thereby flexibly adjusting the size of the temperature zone in the compartment. The movement of the partition plate 3 is achieved by the motor 33 driving the gear 5 to mesh with the rack 4, and the self-locking characteristics of the worm gear 36 and worm 35 mechanism are used to ensure the stability of the position of the partition plate 3. The interior of the compartment is divided into a cold storage area 11, a loading area 12, and a cold conduction area 13. The cold storage area 11 stores cold energy and transfers it to the loading area 12 through the cold conduction area 13. The cold conduction area 13 is equipped with a cooling fan 6, which can control the rotation direction and speed to optimize the temperature distribution and improve the utilization efficiency of cold energy. While enhancing the flexibility and energy efficiency of the compartment loading space, it also ensures a suitable storage environment for goods in each temperature zone through precise temperature control and reduced cold energy loss, and achieves efficient and energy-saving storage and transportation effects.

[0052] Example 2

[0053] Based on the same inventive concept, the present invention provides a carriage loading method, which is applied to the multi-temperature zone carriage in Example 1, and the method comprises:

[0054] S101, according to the quantity and type of goods counted, calculate the occupied space of the goods in each temperature zone through the loading calculation model; wherein the loading calculation model includes a database and a greedy algorithm model, the database contains the size data and temperature requirement data of each kind of goods, the greedy algorithm model uses the quantity and type of goods as input parameters, and the size and delivery order of the compartment 1 as constraints, and uses the greedy algorithm to calculate the occupied space of the goods in each temperature zone according to the size and temperature requirement corresponding to each goods.

[0055] The database serves as an information support, recording in detail the dimensions of each type of cargo (such as length, width, and height) and their specific temperature requirements. This information is an indispensable reference for subsequent calculations and space allocation, ensuring that the cargo can not only be properly placed but also kept at the appropriate temperature.

[0056] The greedy algorithm model is the key to achieving efficient space utilization. It takes the quantity and type of goods as input parameters, while taking into account constraints such as the actual size of compartment 1 and the order of delivery. During the execution of the algorithm, each type of goods will be examined one by one, and the best placement of the goods in compartment 1 will be determined based on its size and temperature requirements using a greedy strategy (i.e., taking the best or optimal choice in the current state at each step, hoping to result in the best or optimal algorithm in the world). This process aims to maximize space utilization while ensuring that all goods meet their specific temperature storage requirements.

[0057] Once the space occupied by the goods in each temperature zone is determined by the greedy algorithm model, the next step is to determine the target position of the partition 3 in the compartment 1 based on these calculation results. The function of the partition 3 is to divide the compartment 1 into different temperature zones to meet the differentiated temperature requirements of different goods.

[0058] S102, determine the target position of each partition plate 3 in the compartment 1 according to the occupied space, and drive the motor 33 to make each partition plate 3 reach the corresponding target position, thereby ensuring that each area can effectively accommodate its corresponding goods, while avoiding the problem of space waste or temperature cross-effect.

[0059] Further, after the driving motor 33 causes each partition plate 3 to reach the corresponding target position, the method further includes:

[0060] S103, in response to the start of the delivery vehicle, starting the refrigeration device for precooling;

[0061] S104, during the delivery process of the delivery vehicle (i.e., the terminal delivery process), the location information of the compartment 1, the cargo information, the temperature data of each temperature zone in the compartment 1, and the delivery information of each cargo are uploaded to the cloud server in real time.

[0062] In other words, once the delivery vehicle is started, the entire delivery process enters the digital and transparent management stage. At this point, the location information in the carriage, detailed cargo information, real-time temperature data of each temperature zone, and specific delivery information of each cargo will be automatically collected by the system and uploaded to the cloud server in real time. This ensures the immediacy of information and provides a solid data foundation for subsequent monitoring and management.

[0063] S105, the cloud server detects whether the delivery vehicle has any abnormality through an abnormality judgment strategy; if not, it continues to monitor; if so, it sends a prompt message to the preset terminal;

[0064] Among them, the abnormal judgment strategy can comprehensively monitor the various states of the delivery vehicles mainly by comparing and analyzing the uploaded data. First, it accurately determines whether the vehicle has deviated from the scheduled transportation route based on the planned driving trajectory and real-time location information of the delivery vehicle, thereby effectively preventing potential route errors or illegal stops. Secondly, the strategy will also strictly compare the temperature data of each temperature zone according to the temperature requirements recorded in the cargo information to ensure that they are always maintained within the preset temperature range, which is crucial to maintaining the quality of the goods and extending the shelf life. Finally, the strategy will also check the delivery information of each cargo to ensure that they can be delivered to the designated customer location accurately, thereby improving the accuracy and reliability of the entire delivery process.

[0065] In addition, if the cloud server detects any abnormal situation, such as vehicle deviation from the route, abnormal temperature or delivery error, it will immediately activate the alarm mechanism and send prompt information to the preset terminal. These prompt information can be quickly conveyed to the relevant operators, drivers and customers, so that they can understand and respond to abnormal situations in time, thus ensuring the continuity and safety of cold chain distribution. Through this intelligent monitoring and management method, the efficiency and quality of cold chain distribution have been significantly improved, and at the same time, it also provides customers with more reliable and high-quality distribution services.

[0066] Based on the same inventive concept, the present invention provides an electronic device, which includes a processor, a storage medium and a computer program. The computer program is stored in the storage medium. When the computer program is executed by the processor, the vehicle loading method in Example 2 is implemented.

[0067] Based on the same inventive concept, the present invention provides a computer-readable storage medium on which a computer program is stored, characterized in that when the computer program is executed by a processor, the carriage loading method in Example 2 is implemented.

[0068] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
