Detailed Implementation

[0019] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0020] This application discloses a vehicle-mounted cabinet with adaptive temperature regulation function, referring to... Figure 1 , Figure 2 and Figure 3 The system includes a cabinet 1 for assembling electronic components. The cabinet 1 has a base 11 at its bottom, an access panel on one side, and an access door 12. A heater 2 is installed inside the cabinet 1, along with a first fan 3 to assist the heater 2 in dissipating heat within the cabinet 1. Ventilation vents are located on the side walls of the cabinet 1, with a second fan 4 at each vent to dissipate hot air from inside the cabinet 1 to the outside. A ventilation opening is located at the bottom of the cabinet 1, with a third fan 5 at each opening to accelerate the airflow through the cabinet 1.

[0021] In this embodiment, other electronic components inside the cabinet 1 are not shown. The heater 2 is an electric heater. A temperature sensor (not shown) is installed on the cabinet 1 to detect the internal operating temperature. The temperature sensor is functionally connected to a controller, which is functionally connected to the heater 2, the first fan 3, the second fan 4, and the third fan 5. The controller may be a PLC integrated circuit system.

[0022] When the temperature sensor detects that the internal temperature of cabinet 1 is below -15 degrees Celsius, indicating that the air temperature is too low, the controller activates heater 2 to dissipate heat within cabinet 1. First fan 3 starts and blows air onto heater 2, accelerating air circulation within cabinet 1 and thus heating the electronic components. At this time, second fan 4 and third fan 5 remain off. When the temperature sensor detects that the internal temperature of cabinet 1 is between -15 degrees Celsius and +25 degrees Celsius, the controller stops heater 2, and first fan 3 and second fan 4 continue to operate to ensure that outside air continuously passes through cabinet 1 and carries away some heat. When the temperature sensor detects that the internal temperature of cabinet 1 is above +25 degrees Celsius, indicating that the air temperature is too high, the controller activates third fan 5. Through the cooperation of third fan 5 with first fan 3 and second fan 4, the speed at which outside air passes through cabinet 1 is further accelerated, thereby improving the heat dissipation efficiency for the electronic components.

[0023] The present application discloses a vehicle-mounted cabinet with adaptive temperature regulation function. Through the coordinated operation of heater 2, first fan 3, second fan 4 and third fan 5, the internal working temperature of the cabinet 1 can be adjusted under various ambient temperatures to match the operation of various electronic components, thereby improving the working stability of various electronic components inside the cabinet 1.

[0024] Specifically, there are two first fans 3 located below the heater 2. Two heat dissipation vents are provided, located on the two side walls of the cabinet 1 respectively. Two second fans 4 are correspondingly located on the inner side wall of the cabinet 1. Three ventilation vents are located at the bottom of the cabinet 1, and three third fans 5 are correspondingly located on the inner bottom wall of the cabinet 1.

[0025] Furthermore, the cabinet 1 is equipped with breathable protective covers 6 at both the heat dissipation vents and the ventilation openings.

[0026] In this embodiment, the protective cover 6 not only prevents external debris from falling directly into the heat dissipation vent and ventilation opening, but also prevents personnel from accidentally touching the second fan 4 and the third fan 5 and causing injury.

[0027] Furthermore, the protective cover 6 includes a louvered mesh cover 61 and a mounting frame 62. The mounting frame 62 is connected to one side of the louvered mesh cover 61 and is embedded in the corresponding heat dissipation / ventilation opening. A dust filter element 63 is also provided inside the mounting frame 62.

[0028] In this embodiment, the mounting frame 62, after being embedded in the corresponding heat dissipation / ventilation opening, can be connected to the cabinet 1 by bolts and nuts. The louvered mesh cover 61 is also bolted to the mounting frame 62 and located on the outside of the cabinet 1. The dust filter element 63 is disposed inside the mounting frame 62, which allows the protective cover 6 of this application to have ventilation capabilities while also filtering and blocking some impurities in the air. The dust filter element 63 is made of sponge.

[0029] Furthermore, the bottom of the louvered mesh cover 61 at the heat dissipation vent is provided with a drain outlet 611 that communicates with the inner cavity of the mounting frame 62.

[0030] In this embodiment, when external moisture passes through the louvered mesh cover 61 at the heat dissipation vent, it can be blocked by the dust filter 63 and discharged from the drain outlet 611 at the bottom, so that the protective cover 6 also has a waterproof function.

[0031] To reduce the vibration experienced by the cabinet 1 during vehicle operation, multiple shock absorbers 7 are installed at intervals between the base 11 and the cabinet 1.

[0032] Furthermore, the inspection door 12 is rotatably mounted on the outer wall of the cabinet 1, the pivot of the inspection door 12 is located above the inspection port, the movable end of the inspection door 12 is connected to the cabinet 1 through the cabinet lock 8, and a first gas spring hydraulic support rod 9 is provided between the cabinet 1 and the inspection door 12. The two ends of the first gas spring hydraulic support rod 9 are rotatably mounted on the inspection door 12 and the inner wall of the cabinet 1, respectively.

[0033] In this embodiment, when the cabinet lock 8 is opened, the first gas spring hydraulic support rod 9 automatically extends, which can drive the maintenance door 12 to flip up and provide support, so that the staff can carry out maintenance, thus improving the convenience of maintenance for the staff.

[0034] Furthermore, the maintenance door 12 is equipped with an operation panel 121, and a cover plate 10 for covering the operation panel 121 is also rotatably mounted on the maintenance door 12. The movable end of the cover plate 10 is connected to the maintenance door 12 via another cabinet lock 8. A second gas spring hydraulic support rod 20 is provided between the cover plate 10 and the maintenance door 12, and the two ends of the second gas spring hydraulic support rod 20 are respectively rotatably mounted on the inner walls of the maintenance door 12 and the cover plate 10.

[0035] In this embodiment, rotating the cover 10 and closing the operation panel 121 can prevent accidental contact or damage to the accessories on the operation panel 121. Opening the corresponding cabinet lock 8 causes the second gas spring hydraulic support rod 20 to automatically extend, driving the cover 10 to rotate and open the operation panel 121, allowing staff to use the accessories on the operation panel 121.

[0036] The implementation principle of a vehicle-mounted cabinet with adaptive temperature regulation function according to an embodiment of this application is as follows: When the internal temperature of the cabinet 1 is below -15 degrees Celsius, the heater 2 operates and dissipates heat inside the cabinet 1. The first fan 3 starts and blows air onto the heater 2, which can accelerate the air circulation efficiency inside the cabinet 1, thereby heating the electronic components. At this time, the second fan 4 and the third fan 5 do not start. When the internal temperature of the cabinet 1 is between -15 degrees Celsius and 25 degrees Celsius, the heater 2 stops heating, and the first fan 3 and the second fan 4 continue to start to ensure that outside air can continuously pass through the inside of the cabinet 1 and take away some heat. When the internal temperature of the cabinet 1 is above 25 degrees Celsius, the third fan 5 continues to start. Through the cooperation of the third fan 5 with the first fan 3 and the second fan 4, the speed at which outside air passes through the inside of the cabinet 1 can be further accelerated, thereby improving the heat dissipation efficiency of the electronic components and improving the working stability of the electronic components inside the cabinet 1.
