[0024] Example:

[0025] See also Figures 1-5 The present invention provides the following technical solutions: a heat-insulating refrigeration loading box for loading, comprising a loading box 1, an installation box 2 and a space adjustment structure; a plurality of temperature sensors are installed inside the loading box 1, distributed in different areas, to monitor the temperature distribution inside the box in real time;

[0026] A box door 4 is installed in the middle of the front side of the loading box 1, an installation box 2 is installed on the left side of the loading box 1, and a heat dissipation box 3 is installed on the left side of the installation box 2. An air conditioner and a regulating motor are installed in the inner cavity of the loading box 1; the air conditioner is connected to the loading box 1 to the right through a pipe, the motor is arranged at the top of the inner cavity of the installation box 2, and a threaded rod 11 is installed at the transmission end of the motor; the heat dissipation box 3 is connected to the installation box 2, and a cooling fan is installed in the heat dissipation box 3 to extract the air in the installation box 2;

[0027] The space adjustment structure is composed of a blocking plate 5, a fixing frame 6 and a hanging frame 8. The blocking plate 5 intercepts the inner cavity of the loading box 1 to cut off the inner cavity of the loading box 1. The fixing frame 6 is installed in the middle of the top of the inner cavity of the loading box 1. The left and right sides and bottom of the fixing frame 6 are provided with adjustment slots 7.

[0028] A groove is provided in the middle of the top of the blocking plate 5, and a cross-shaped sliding block 12 is provided in the groove. The sliding block 12 is clamped in the adjustment groove 7, and the blocking plate 5 slides in the adjustment groove 7 through the sliding block 12; limit switches are provided at both ends of the threaded rod 11. When the blocking plate 5 moves to the limit position, the limit switch can be triggered in time to stop the motor from running, preventing damage to the equipment due to misoperation; the sliding block 12 and the adjustment groove 7 are connected to each other, so that the top of the blocking plate 5 is sealed;

[0029] A screw hole is provided in the middle of the sliding block 12, and the threaded rod 11 is inserted into the fixing frame 6 and the sliding block 12, and the screw holes of the threaded rod 11 and the sliding block 12 are screwed together. The threaded rod 11 is driven to rotate by the motor, and then the threaded rod 11 drives the baffle plate 5 to adjust in the loading box 1. By adjusting the position of the baffle plate 5 in the loading box 1, the storage space is changed, thereby improving the utilization rate of the air conditioner;

[0030] A hanging bracket 8 is symmetrically mounted on the inner top of the baffle plate 5, a grooved pulley is mounted on the hanging bracket 8, a slide bar 9 is provided below the grooved pulley, and the grooved pulley is downwardly engaged with the slide bar 9, and both ends of the slide bar 9 are fixed to the inner wall of the loading box 1, and the baffle plate 5 is supported by the slide bar 9 and the hanging bracket 8;

[0031] The grooved pulley of the hanging frame 8 is made of high-strength engineering plastics and is equipped with precision ball bearings inside to reduce the rotational resistance of the pulley; the slide bar 9 is made of stainless steel and the surface is polished to reduce the friction coefficient between the grooved pulley and the slide bar 9; the bottom of the blocking plate 5 is symmetrically equipped with load-bearing wheels 10 on both sides to assist the bottom movement of the blocking plate 5;

[0032] The body of the loading box 1 is made of a new multi-layer composite insulation material. A high-performance insulation layer, such as aerogel felt or vacuum insulation panels, is sandwiched between the inner and outer metal sheets to further enhance the box's thermal insulation, reduce heat transfer, and lower air conditioning energy consumption. Sealing strips are used at each joint of the box. The strips are made of a rubber material that is resistant to low temperatures, aging, and has good elastic recovery properties. This effectively prevents cold air leakage in different temperature environments and ensures temperature stability within the loading box 1.

[0033] The baffle 5 is constructed from a lightweight, high-strength aluminum alloy frame filled with thermally insulating foam, ensuring structural strength while effectively preventing heat transfer between partitions. The aluminum alloy frame is anodized to enhance its corrosion and wear resistance. A flexible, thermally insulating silicone gasket is installed at the contact edge between the baffle 5 and the inner wall of the loading box 1. This gasket, made of silicone, adheres tightly to the inner wall of the loading box 1 during movement, preventing cold air from escaping through the gap.

[0034] The load-bearing wheels 10 are solid wheels made of rubber, which have excellent wear resistance and shock absorption properties. High-precision bearings are installed in the hubs of the load-bearing wheels 10 to ensure flexible wheel rotation. A guide track (not shown in the figure) is provided at the bottom of the loading box 1, corresponding to the travel path of the load-bearing wheels 10. The guide track is made of aluminum alloy and has an anti-slip surface treatment, so that the load-bearing wheels 10 can move along the predetermined track, thereby improving the stability and reliability of the movement of the baffle 5.

[0035] The interior of the heat dissipation box 3 adopts a heat dissipation method that combines finned heat sinks and a heat dissipation fan. The finned heat sink is made of aluminum alloy and has a large heat dissipation area, which can quickly conduct the heat inside the installation box 2. The heat dissipation fan uses a large-diameter, low-speed axial flow fan to reduce fan noise and energy consumption while ensuring sufficient air volume. Air filters are installed at the air inlet and outlet of the heat dissipation box 3 to prevent dust and debris from entering the heat dissipation box 3 and affecting the heat dissipation effect and equipment operation stability.

[0036] The air conditioning system uses variable frequency compressor technology, which can automatically adjust the speed of the variable frequency compressor according to the actual cooling demand in the loading box 1, reducing power consumption during low-load operation and improving energy utilization. The intelligent defrost technology uses sensors to monitor the frost on the evaporator surface in real time. When the frost reaches a certain level, the defrost program is automatically started, using hot air bypass or electric heating to quickly defrost. This reduces energy waste and temperature fluctuations during the defrost process, ensuring the continuous and efficient operation of the air conditioning system. All variable frequency compressors with the same function on the market can be used.

[0037] Working Principle: When the interior space of loading box 1 needs to be adjusted, the motor mounted on the top of the inner cavity of installation box 2 is activated. The motor drives the threaded rod 11 to rotate. Since the threaded rod 11 is screwed to the screw hole of the cross-shaped sliding block 12 on the top of the baffle plate 5, when the threaded rod 11 rotates, the sliding block 12 slides along the adjustment slot 7 of the fixing frame 6 according to the principle of screw transmission.

[0038] The interconnected adjustment slots 7 and slide blocks 12 ensure a top seal, preventing cold air leakage. Simultaneously, grooved pulleys on the symmetrically mounted hanger brackets 8 on the inner top of the baffle plate 5 roll along the slide bars 9, providing auxiliary support for the baffle plate 5 and ensuring its vertical stability. Load-bearing wheels 10 on either side of the baffle plate 5's bottom roll along the bottom of the loading box 1, assisting in the movement of the bottom of the baffle plate 5. This allows the baffle plate 5 to be adjusted within the loading box 1, thereby altering the storage space within the loading box 1.

[0039] The air conditioner in loading box 1 operates, delivering cool air to the right through the ductwork into loading box 1, cooling the space within. Heat within installation box 2 is extracted by the cooling fan in heat dissipation box 3. When the cooling fan operates, it draws the hot air from installation box 2 and discharges it through heat dissipation box 3 to the outside environment. The air flow within heat dissipation box 3 helps remove heat from installation box 2, ensuring the proper operation of the air conditioning system and preventing heat accumulation that affects the performance and service life of the air conditioner.

[0040] By adjusting the position of the baffle 5 within the loading box 1, the space within the loading box 1 can be rationally divided according to the actual volume and distribution of the cargo. For example, when the cargo is small and concentrated on one side, the baffle 5 can be moved to a suitable position so that the cold air from the air conditioner can circulate more concentratedly in the area where the cargo is located, thereby improving the utilization rate of the air conditioner, reducing cooling waste, and more quickly reaching and maintaining the desired temperature.
