Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of goods transportation, and particularly to a small transport vehicle compartment adjusting device and method based on goods characteristics. BACKGROUND

[0002] In the field of modern logistics and commercial distribution, small transport vehicles play an important role in the transportation link from warehouses to logistics vehicles and then to commercial markets. However, the current design of the compartments of such small transport vehicles has many limitations and cannot meet the growing demand for efficient and accurate transportation.

[0003] Firstly, the space layout of the compartments of such small transport vehicles lacks flexibility. The width is about one meter and the length does not exceed two meters, and the space is limited, but the internal structure is fixed and cannot be adjusted according to the size, shape and characteristics of the goods. For example, when transferring goods from a warehouse to a logistics vehicle, various specifications of packaging boxes are often encountered, including small electronic product packaging boxes and large furniture part packaging. Due to the inability to flexibly change the compartment space, small-size goods may be damaged due to mutual extrusion, and large-size goods may not be able to be loaded smoothly, resulting in low transportation efficiency and increasing the risk of damage to goods.

[0004] Secondly, the sorting and placing of goods completely rely on manual operation. Warehouse workers need to spend a lot of time and effort to move goods into the compartments of small transport vehicles and place them neatly by hand. The same is true for the distribution link from the warehouse to the commercial market. Workers not only have a high labor intensity, but also have low efficiency. In particular, during the peak business period such as the promotion season, manual operation cannot meet the rapid demand for goods circulation, resulting in goods backlog and affecting the smooth operation of the entire logistics and distribution chain.

[0005] Furthermore, there is a lack of intelligent goods location planning and compartment joint control system. In actual transportation, different goods may have different priorities or special requirements, such as fresh goods that need to be preferentially distributed and kept at a certain distance from other goods. However, the existing compartments of small transport vehicles cannot arrange the positions in advance according to the characteristics of the goods, and each compartment is independent of each other, so unified intelligent management cannot be achieved. When multiple vehicles are operating simultaneously, it is impossible to plan the allocation of goods, resulting in low utilization of compartment space and increasing transportation costs.

[0006] With the continuous rise in labor costs and the increasing demand for logistics and distribution efficiency and accuracy, the traditional small transport vehicle compartments that rely on manual operation, lack flexibility and intelligence have gradually become a bottleneck restricting the development of the industry.

[0038] The threaded sleeve 4 is arranged at the bottom of the support frame 22, and the threaded sleeve 4 is fixedly connected with the support frame 22.

[0041] It should be noted that a plurality of groups of adjusting devices are horizontally arranged in the vehicle compartment, the adjusting device is composed of a plurality of partition plates 2, the bottom of the lowermost partition plate 2 is not provided with a threaded sleeve 4, the top of the uppermost partition plate 2 is not provided with a threaded rod 3, and in addition, the bottom of the vehicle compartment is provided with a weighing device capable of detecting the total bearing capacity in the vehicle compartment, so as to judge whether the vehicle is overloaded.

[0042] In use, when the goods need to be loaded, the distance between the partition plates 2 of the corresponding layer is first increased, so as to facilitate the carrying of the goods, and then the goods are placed in the corresponding position, and the size between the partition plates 2 is adjusted according to the size of the goods, in addition, the partition plates 2 of the same layer can be arranged in a high-low state in sequence, and the lower partition plate 2 can be limited by the higher partition plates 2 on both sides, so as to avoid displacement and falling of the goods on the partition plate 2, and at the same time, due to the height of the goods itself, the goods on both sides can clamp the goods on the higher partition plate 2 in the middle, so as to realize the positioning of the goods.

[0043] Referring to Figures 1-8 As an optional embodiment: the embodiment proposes a small transport vehicle compartment adjusting method based on the characteristics of goods, comprising a small transport vehicle compartment adjusting device based on the characteristics of goods, and further comprising the following steps: S1: The intelligent control unit receives the cargo position planning and space adjustment instructions sent by the external system, and the instructions include cargo type, size, weight, and special transportation demand information; the intelligent control unit is a processor or a PLC controller, and the transportation personnel can input the cargo type, size, weight, and special transportation demand information into the intelligent control unit through wireless transmission. The wireless transmission can be network transmission, Bluetooth transmission, or WiFi transmission.

[0044] S2: The cargo type sensing device detects the characteristics of the cargo entering the car compartment and obtains the actual physical parameters of the cargo. Specifically, the cargo type sensing device includes a weight sensor, an infrared sensor, and a temperature sensor. The actual physical parameters include the weight, size, shape, and ambient temperature of the cargo. The weight sensor is used to detect the weight of the cargo on the partition plate 2. The infrared sensor is used to scan the size and shape of the cargo. The temperature sensor is used to detect the ambient temperature.

[0045] It should be noted that the car compartment can be set according to the demand to set the number of small transportation car compartment adjustment devices corresponding to the characteristics of the cargo. Each support frame 22 of each partition plate 2 is provided with a weight sensor. When the cargo is placed on the partition plate 2, the weight of the cargo can be weighed. Since a variety of different types of cargo may be transported at a time, the weight detection of the weight sensor can distinguish the types of the cargo. According to the maximum weight that a single partition plate 2 can carry, the transportation personnel can know the maximum number of cargos that a single partition plate 2 can carry, so as to avoid the risk of cargo damage caused by the insufficient carrying capacity of the partition plate 2. When the cargo is placed, the weight sensor converts the sensed weight analog signal into a digital signal and transmits it to the intelligent control unit. The intelligent control unit determines whether the weight exceeds the preset threshold. If it exceeds, an overweight alarm is issued.

[0046] The infrared sensor is arranged at the entrance of the car compartment and at both sides of the car compartment. The infrared sensor is arranged around the entrance of the car compartment. After the cargo is loaded, the infrared sensor obtains the cargo contour point cloud data by emitting and receiving reflected infrared rays. The intelligent control unit processes the point cloud data, constructs a three-dimensional model of the cargo, and extracts the actual size and shape information of the cargo. After obtaining the size and shape information of the cargo, the transportation personnel can determine the type of the cargo, which is convenient for guiding the transportation personnel to place it in the planned area for placement, and maintaining the uniform placement of the cargo.

[0047] S3: The intelligent control unit compares and verifies the actual physical parameters with the cargo information in the external system instructions to generate a spacing adjustment scheme for partition 2. Since some goods may undergo secondary packaging or the packaging specifications may be different, there may be discrepancies between the dimensions entered by the system and the actual dimensions. Therefore, if the size of the item is detected to exceed the preset difference, such as exceeding five percent, the intelligent control unit will automatically adjust the spacing setting scheme of partition 2 according to the size difference to ensure the normal placement of goods and the maximum utilization of space.

[0048] S4: The intelligent control unit controls the movement of partition 2 according to the adjustment scheme, adjusting the spacing between partitions in the compartment to meet the cargo storage requirements. When the actual physical parameters of the cargo deviate from the instructions of the external system by more than a preset range, or when cargo position shifts or abnormal temperature fluctuations are detected, the intelligent control unit feeds back abnormal information to the external system and adjusts the spacing of partition 2 or the transportation environment parameters according to preset rules. After the cargo is placed on partition 2, the infrared sensors on both sides of the compartment continue to scan to determine whether the spacing of the cargo placed on partition 2 is appropriate. If it is not appropriate, it feeds back to the intelligent control unit, which generates an adjustment scheme for further adjustment.

[0049] If the cargo experiences a significant displacement due to bumps during transport, the infrared sensors on both sides of the vehicle will detect the displacement and send the displacement data to the intelligent control unit. The intelligent control unit will then appropriately reduce the spacing of the partition 2 based on the displacement status to prevent excessive movement of the cargo.

[0050] The process of adjusting the partition 2 is as follows: the intelligent control unit sends a control signal to the drive mechanism 5, the drive mechanism 5 drives the threaded rod 3 to rotate, and drives the threaded sleeve 4 and the connected partition 2 to move linearly along the slide rail 1; The position sensor on the slide rail 1 provides real-time feedback on the position information of the partition 2, and the intelligent control unit fine-tunes the action of the drive mechanism 5 based on the information until the partition 2 moves to the designated position.

[0051] S5: For goods with special transportation needs, the intelligent control unit activates the corresponding auxiliary facilities to complete the adaptation to the transportation environment.

[0052] The carriage can be equipped with separate insulated compartments according to transportation needs. These compartments contain heating and cooling equipment, and temperature sensors are located within them. For fresh produce requiring insulation, the sensors monitor the temperature in real time and continuously transmit the data to an intelligent control unit. The control unit compares the real-time temperature with a preset range suitable for storing fresh produce. If the temperature exceeds the upper limit, the control unit activates the cooling equipment to lower the compartment temperature; if the temperature falls below the lower limit, the control unit activates the heating equipment or adjusts the insulation measures to ensure the temperature remains within a suitable range. Furthermore, the temperature sensor data can be used to record and analyze temperature changes during transport. If abnormal temperature fluctuations are detected and persist for an extended period, the control unit issues an alarm, indicating a potential impact on the quality of the fresh produce. Simultaneously, it feeds this information back to an external system for further action, such as accelerating transport or adjusting the delivery schedule.

[0053] In summary, by identifying the type, size, and weight of goods, and then comparing them with preset goods types, sizes, and weights, the adjustment of partition 2 can be further optimized, enabling more effective use of space and preventing damage during the transportation of goods.

[0054] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of the present invention.
