Description

Technical Field

[0001] This invention relates to the field of refrigeration technology for refrigerated trucks, and more specifically to a refrigeration unit for refrigerated trucks equipped with an intelligent temperature sensing system. Background Technology

[0002] Refrigerated trucks are enclosed van-type transport vehicles used to maintain the temperature of frozen or fresh goods. Refrigerated trucks are special transport vehicles equipped with refrigeration units and polyurethane insulated compartments. Refrigerated trucks consist of a special vehicle chassis running on a chassis, an insulated compartment, a refrigeration unit, a temperature recorder inside the compartment, and other components. The refrigeration unit determines the freezing or preservation effect of the refrigerated truck and is the guarantee for refrigerated transport.

[0003] A refrigeration unit is a machine that transfers heat from a cooled object to the surrounding environment to obtain cooling capacity. A refrigeration unit generally consists of a compressor, condenser, expansion valve, evaporator, and control system. Refrigeration units can maintain a constant temperature inside a refrigerated truck, thus keeping the goods inside fresh and ensuring they maintain good freshness even after long-term transportation. However, traditional refrigeration units have the following problems:

[0004] When the refrigeration unit is working, it has two sensors installed inside to detect the temperature inside the compartment and the temperature of the defrost pipe, thereby regulating the refrigeration temperature to ensure a constant temperature inside the compartment. However, it cannot regulate the outlet temperature of the refrigeration unit. When the air outlet of the refrigeration unit is blocked, the refrigeration unit cannot achieve a good cooling effect inside the compartment. In this case, the cold air is likely to blow directly downwards, which may damage the goods below.

[0005] The cold air coming out of the refrigeration unit's vent blows into the passenger compartment. The passenger compartment is a relatively enclosed environment, so the air circulation inside is relatively slow. Therefore, the cold air entering the passenger compartment cannot cool the goods in different locations in a relatively even way. Summary of the Invention

[0006] In order to overcome the above-mentioned defects of the prior art, the embodiments of the present invention provide a refrigeration unit for refrigerated trucks with an intelligent temperature sensing system to solve the technical problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a refrigeration unit for a refrigerated truck equipped with an intelligent temperature sensing system, comprising a truck body, a data acquisition unit, a data transmission unit, a data display unit, a data analysis unit, and an execution unit. The data acquisition unit collects temperature data inside the truck body, air outlet temperature and wind speed data, and temperature data of the defrost pipe inside the refrigeration unit through an in-cabin temperature sensor, an air outlet temperature sensor, and a defrost sensor. The data transmission unit sends the data collected by the data acquisition unit to the data display unit. The data display unit receives the data and displays it on a screen. The data display unit controls the execution unit to operate according to the buttons on the data adjustment controller on the screen. The data analysis unit collects the data collected by the data acquisition unit and controls the execution unit to operate. The execution unit adjusts the operating state of the refrigeration unit.

[0008] A refrigeration unit is fixedly connected to the side of the vehicle body. An internal temperature sensor is fixedly connected to the side of the refrigeration unit. An outlet temperature sensor is provided at the front end of the air outlet of the refrigeration unit. The refrigeration unit is electrically connected to a controller. An airflow mechanism is fixedly connected to the side of the vehicle body away from the refrigeration unit. A deceleration mechanism is provided inside the airflow mechanism. The side of the deceleration mechanism is fixedly connected to the side of the vehicle body. A defrost sensor is fixedly connected to the side of the defrost pipe inside the refrigeration unit.

[0009] In a preferred embodiment, the airflow mechanism includes a support cylinder for support, a rotating shaft is movably connected inside the support cylinder, a wind turbine blade is fixedly connected to one side of the rotating shaft, and a rotating blade is fixedly connected to the other side of the rotating shaft.

[0010] In a preferred embodiment, the side of the support cylinder closest to the wind turbine blade is a cone, and the deceleration mechanism is located inside it; the side of the support cylinder closest to the rotating blade is a conical cylinder, and the rotating blade is located inside it; the middle part of the support cylinder is a cylinder.

[0011] In a preferred embodiment, the deceleration mechanism includes a fixed upper arc plate, an inner cavity for receiving groove, a fixed plate fixedly connected to the middle of the receiving groove, electromagnets fixedly connected to both ends of the upper and lower sides of the receiving groove, a limit rod fixedly connected to the bottom end of the electromagnet, a magnetic plate movably connected to the side of the limit rod, the upper arc plate fixedly connected to the side of the magnetic plate, a rotating shaft provided at the bottom end of the upper arc plate, and an electromagnet provided at the bottom end of the rotating shaft.

[0012] In a preferred embodiment, a limiting rod is sleeved on the side of the limiting rod, the top end of the limiting rod contacts the bottom end of the magnetic plate, the bottom end of the limiting rod contacts the top end of the limiting rod, and the upper arc plate and the lower arc plate are mirror-symmetrical about the center of the rotation axis.

[0013] In a preferred embodiment, the controller includes a power button, a display screen, a photosensitive area, an increase button, a defrost button, a view button, a setting button, and a decrease button. When the power button is pressed briefly for 1 second or less, the refrigeration unit starts working; when the power button is pressed for more than 3 seconds, the refrigeration unit stops working. The increase and decrease buttons are used to adjust the temperature inside the vehicle compartment. When the refrigeration unit is working normally, pressing the view button for more than 3 seconds can switch between air supply and return modes. When "CF" and "HF" appear on the display screen, pressing the increase and decrease buttons briefly for 1 second can switch modes. Pressing the defrost button for more than 2 seconds initiates the defrost operation of the refrigeration unit.

[0014] In a preferred embodiment, when the temperature detected by the defrost sensor is lower than the set defrost temperature, the data acquisition unit sends a first instruction to the processing unit through the data transmission unit. The processing unit controls the defrost button to flash to remind the driver to perform defrosting. If the defrost button flashes for ten minutes and no defrosting operation is performed, the processing unit automatically controls the defrost module in the execution unit to work.

[0015] In a preferred embodiment, when the internal temperature sensor detects that the temperature inside the vehicle compartment is higher than the set internal temperature, the data transmission unit sends a command G to the analysis unit. The analysis unit then controls the decrease button to flash. If the decrease button flashes for ten minutes without any cooling operation, the processing unit automatically controls the cooling module in the execution unit to operate. Conversely, when the internal temperature sensor detects that the temperature inside the vehicle compartment is lower than the set internal temperature, the data transmission unit sends a command D to the analysis unit. The analysis unit then controls the increase button to flash. If the increase button flashes for ten minutes without any cooling operation, the processing unit automatically controls the cooling module in the execution unit to operate.

[0016] In a preferred embodiment, when the air outlet temperature sensor detects that the air outlet temperature is two degrees higher than the set air outlet temperature, the air outlet temperature sensor sends command G; when the air outlet temperature sensor detects that the air outlet temperature is two degrees lower than the set air outlet temperature, the air outlet temperature sensor sends command D. When the air outlet temperature is high or the vehicle body is not properly insulated, the temperature inside the vehicle body will be high.

[0017] The technical effects and advantages of this invention are as follows:

[0018] 1. This invention includes a refrigeration unit, an internal temperature sensor, an air outlet temperature sensor, and a defrost sensor. The internal temperature sensor can detect the temperature inside the vehicle compartment, the defrost sensor can detect the temperature of the defrost pipe to enable rapid defrosting, and the air outlet temperature sensor can quickly detect the temperature of the air outlet, thereby enabling more precise control of the temperature inside the vehicle compartment.

[0019] 2. This invention uses a support cylinder, a rotating shaft, wind turbine blades, and rotating blades. When the vehicle is moving, airflow is generated in front of the vehicle, which drives the wind turbine blades to rotate. When the wind turbine blades rotate, they drive the rotating blades to rotate through the rotating shaft. The rotating blades generate wind force, which accelerates the airflow inside the refrigerated truck, thereby making the temperature in various parts of the refrigerated truck more balanced.

[0020] 3. When the temperature sensor inside the compartment and the temperature sensor at the air outlet of this invention detect a high temperature, they promptly remind the driver to perform cooling operations. If the driver does not operate within ten minutes, the cooling operation will be automatically performed to prevent damage to the goods inside the compartment. When the outlet temperature is low, the temperature inside the compartment will be low, which may cause the goods inside the compartment to freeze. Therefore, a heating reminder will also be issued to ensure that the temperature inside the compartment remains stable. Attached Figure Description

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The refrigeration unit of a refrigerated truck with an intelligent temperature sensing system involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example 1, refer to Figure 1 , Figure 2 as well as Figure 3 This invention provides a refrigeration unit for a refrigerated truck equipped with an intelligent temperature sensing system, including a truck body 1, a refrigeration unit 2 fixedly connected to the side of the truck body 1, an internal temperature sensor 3 fixedly connected to the side of the refrigeration unit 2, an outlet temperature sensor 4 provided at the front end of the air outlet of the refrigeration unit 2, a controller 5 electrically connected to the refrigeration unit 2, an airflow mechanism 6 fixedly connected to the side of the truck body 1 away from the refrigeration unit 2, a deceleration mechanism 8 provided inside the airflow mechanism 6, the side of the deceleration mechanism 8 fixedly connected to the side of the truck body 1, and a defrost sensor 7 fixedly connected to the side of the defrost pipe inside the refrigeration unit 2.

[0032] In this embodiment, in addition to the conventional refrigeration unit's internal temperature sensor 3 for detecting the temperature inside the compartment 1 and the defrost sensor 7 for detecting the temperature of the defrost pipe, an external temperature sensor 4 for detecting the temperature of the air outlet of the refrigeration unit 2 is also provided. By providing the external temperature sensor 4, the temperature of the air outlet can be quickly detected, thereby enabling more precise control of the temperature inside the compartment 1. Furthermore, it should be noted that the compartment 1 is the part of the entire compartment closest to the driver's cab. The internal temperature sensor 3 is model PT100, the defrost sensor 7 is model 9734-REFR, and the external temperature sensor 4 is model TP-3030-1. The controller 5 is located on the refrigerated truck's dashboard, and the driver can observe the data in the controller 5 and control the working status of the refrigeration unit 2 through the controller 5.

[0033] Reference Figure 3 and Figure 4 The airflow mechanism 6 includes a support cylinder 601 for support. A rotating shaft 602 is movably connected inside the support cylinder 601. A wind turbine blade 603 is fixedly connected to one side of the rotating shaft 602, and a rotating blade 604 is fixedly connected to the other side of the rotating shaft 602. The side of the support cylinder 601 near the wind turbine blade 603 is a cone, and the deceleration mechanism 8 is located inside it. The side of the support cylinder 601 near the rotating blade 604 is a conical cylinder, and the rotating blade 604 is located inside it. The middle part of the support cylinder 601 is a cylinder.

[0034] In this embodiment, when the refrigerated truck is in motion, airflow is generated in front of the truck, which drives the wind turbine blades 603 to rotate. When the wind turbine blades 603 rotate, they drive the rotating blades 604 to rotate via the rotating shaft 602. The rotating blades 604 generate wind when they rotate, which accelerates the airflow inside the refrigerated truck, thereby making the temperature in various parts of the refrigerated truck more balanced. Since the airflow mechanism 6 is located in front of the truck body 1, it will not increase the resistance of the refrigerated truck. The two sides of the support cylinder 601 are cones or conical cylinders to accommodate the deceleration mechanism 8 and the rotating blades 604, while the cylinder connected in the middle is used to support and balance the rotating shaft 602.

[0035] Reference Figure 4 and Figure 5 The deceleration mechanism 8 includes an upper arc plate 801 for fixing. The upper arc plate 801 has a receiving groove inside. A fixing plate 805 is fixedly connected to the middle of the receiving groove. Electromagnets 803 are fixedly connected to both ends of the upper and lower sides of the receiving groove. A limit rod 806 is fixedly connected to the bottom end of the electromagnet 803. A magnetic plate 804 is movably connected to the side of the limit rod 806. The upper arc plate 801 is fixedly connected to the side of the magnetic plate 804. A rotating shaft 602 is provided at the bottom end of the upper arc plate 801. An electromagnet 803 is provided at the bottom end of the rotating shaft 602. A limit rod 806 is sleeved on the side of the limit rod 806. The top end of the limit rod 806 contacts the bottom end of the magnetic plate 804. The bottom end of the limit rod 806 contacts the top end of the limit rod 806. The upper arc plate 801 and the lower arc plate 802 are mirror-symmetrical about the center of the rotating shaft 602.

[0036] In this embodiment, when the electromagnet 803 is energized, a magnetic repulsion force is generated between it and the magnetic plate 804, which causes the magnetic plate 804 to move downward. When the magnetic plate 804 moves downward, it drives the upper arc plate 801 to move downward. When the upper arc plate 801 moves downward, it will contact the rotating shaft 602, thereby reducing the rotation of the rotating shaft 602. The lower arc plate 802 is mirror-symmetrical to the upper arc plate 801, so the lower arc plate 802 will move upward and contact the rotating shaft 602 to slow it down.

[0037] Reference Figure 6 and Figure 7 The controller 5 includes a power button 501, a display screen 502, a photosensitive area 503, an increase button 504, a defrost button 505, a view button 506, a setting button 507, and a decrease button 508. When the power button 501 is pressed briefly for 1 second or less, the refrigeration unit 2 starts working. When the power button 501 is pressed for more than 3 seconds, the refrigeration unit 2 stops working. The increase button 504 and the decrease button 508 are used to adjust the temperature inside the carriage 1. When the refrigeration unit 2 is working normally, pressing the view button 506 for more than 3 seconds can switch between the air supply and return modes. When "CF" and "HF" appear on the display screen 502, pressing the increase button 504 and the decrease button 508 briefly for 1 second can switch modes. Pressing the defrost button 505 for more than 2 seconds will cause the refrigeration unit 2 to defrost.

[0038] In this embodiment, the refrigeration unit 2 is intelligently controlled by various buttons on the controller 5, thereby precisely controlling the temperature inside the carriage 1 to ensure the freshness of the goods after transportation. In addition, it should be noted that CF is the air outlet mode and HF is the air return mode.

[0039] Reference Figure 8 It also includes a data acquisition unit, a data transmission unit, a data display unit, a data analysis unit, and an execution unit. The data acquisition unit collects temperature data inside the compartment 1, air outlet temperature and wind speed data, and defrost pipe temperature data inside the refrigeration unit 2 through the internal temperature sensor 3, the air outlet temperature sensor 4, and the defrost sensor 7. The data transmission unit sends the data collected by the data acquisition unit to the data display unit. The data display unit receives the data and displays it on the display screen 502. The data display unit controls the execution unit to work according to the buttons on the data adjustment controller 5 on the display screen 502. The data analysis unit collects the data collected by the data acquisition unit and controls the execution unit to work. The execution unit adjusts the working state of the refrigeration unit 2.

[0040] Furthermore, when the temperature detected by the defrost sensor 7 is lower than the set defrost temperature, the data acquisition unit sends a first instruction to the processing unit through the data transmission unit. The processing unit controls the defrost button 505 to flash, reminding the driver to perform defrosting. If the defrost button 505 flashes for ten minutes without any defrosting operation, the processing unit automatically controls the defrost module in the execution unit to operate. Refrigerated trucks need to perform defrosting during transportation to ensure that the refrigeration unit can continuously cool. This application first uses the flashing method of the defrost button 505 to remind the driver to perform defrosting in a timely manner. When the driver is focused on driving and does not perform defrosting, the execution unit can also automatically perform defrosting, thereby ensuring that the refrigeration unit can continue to operate healthily.

[0041] Furthermore, when the internal temperature sensor 3 detects that the temperature inside the compartment 1 is higher than the set internal temperature, it sends a command G to the analysis unit through the data transmission unit. The analysis unit controls the decrease key 508 to flash. If the decrease key 508 flashes for ten minutes without cooling, the processing unit automatically controls the cooling module in the execution unit to work. When the internal temperature sensor 3 detects that the temperature inside the compartment 1 is lower than the set internal temperature, it sends a command D to the analysis unit through the data transmission unit. The analysis unit controls the increase key 504 to flash. If the increase key 504 flashes for ten minutes without cooling, the processing unit automatically controls the cooling module in the execution unit to work. When the air outlet temperature sensor 4 detects that the air outlet temperature is two degrees higher than the set air outlet temperature, it sends a command G. When the air outlet temperature sensor 4 detects that the air outlet temperature is two degrees lower than the set air outlet temperature, it sends a command D. When the air outlet temperature is high or the compartment 1 fails to perform good insulation, the temperature inside the compartment 1 will be high.

[0042] In this embodiment, when the temperature sensor 3 inside the compartment and the temperature sensor 4 at the air outlet detect a high temperature, they can promptly remind the driver to perform cooling operations. If the driver does not operate within ten minutes, the cooling operation will be automatically performed to prevent damage to the goods inside the compartment 1. When the outlet temperature is low, the temperature inside the compartment 1 will be low, which may cause the goods inside the compartment 1 to freeze. Therefore, a heating reminder will also be issued to ensure that the temperature inside the compartment 1 remains stable.

[0043] The working principle of the present invention: The air outlet temperature sensor 4 is located at the air outlet of the refrigerator 2. Therefore, the cold air coming out of the refrigerator 2 can be detected by the air outlet temperature sensor 4 and displayed in the controller 5. When the air outlet temperature sensor 4 detects that the cold air blown out by the refrigerator 2 is insufficient, it can be adjusted in time.

[0044] When the refrigerated truck is in operation, the entire body 1 is in a moving state, so airflow is generated in front of the body 1. The airflow drives the fan blades 603 to rotate. When the fan blades 603 rotate, they drive the rotating blades 604 to rotate through the rotating shaft 602. When the rotating blades 604 rotate, the generated gas is blown into the interior of the body 1 and is in the same direction as the gas blown out of the air outlet of the refrigeration unit 2. This ensures that the cold air blown out by the refrigeration unit 2 can reach a farther position, thereby increasing the gas flow rate inside the refrigeration unit 2 and ensuring that the temperature of goods in different positions inside the refrigeration unit 2 remains consistent.

[0045] The outlet temperature sensor 4 detects the temperature of the cold air blown out by the refrigeration unit 2. The detected value is the overall value of the blowing speed of the refrigeration unit 2 and the rotation speed of the rotating blade 604. When the cooling effect is good and the speed of the cold air needs to be accurately adjusted, the electromagnet 803 is energized. After the electromagnet 803 is energized, a magnetic repulsion force is generated between it and the magnetic plate 804, which causes the magnetic plate 804 to move downward. When the magnetic plate 804 moves downward, it drives the upper arc plate 801 to move downward. When the upper arc plate 801 moves downward, it will contact the rotating shaft 602, thereby reducing the rotation speed of the rotating shaft 602 and adjusting the overall speed of the cold air. In addition, when the refrigerated truck travels at a high speed, the rotation speed of the rotating shaft 602 will increase accordingly. The upper arc plate 801 limits the rotation speed of the rotating shaft 602 to prevent the equipment from shaking due to excessive rotation speed.
