[0020] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific embodiments of the utility model will be described in detail below with reference to the accompanying drawings.

[0021] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, but the present application can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without departing from the connotation of the present application, therefore the present application is not limited by the specific embodiments disclosed below.

[0022] As Figure 1 shown, an outdoor car charging pile shell structure, including setting on the base 5 on the shell 1, the shell 1 one side is equipped with charging gun head 4, and the front end of shell 1 is equipped with front cover plate, the front cover plate is equipped with the placing opening of charging gun head 4 adaptation;The inside of the shell 1 is provided with cooling pipe 2, the cooling pipe 2 is fixed in the inner wall of shell 1 by buckle, the both sides of the shell 1 are provided with opening and closing type ventilation device 3, the opening and closing type ventilation device and cooling pipe 2 are in contact.

[0023] Through opening and closing type ventilation device 3, the import and export size of ventilation device can be controlled, so that the ventilation process is controllable, especially when affected by external environment, adaptive adjustment can be made, such as when it is rainy or heavy humid weather, to reduce the influence of wet air on the inside, opening and closing type ventilation device 3 can be controlled to adjust the import and export size or closed, to reduce the influence of external environment on the inside as much as possible, and the cooling pipe 2 filled with cooling medium can absorb internal heat, and the heat exchange device (here, it can be a micro compressor, etc., specifically, it can be assembled to the upper part of shell 1, and the upper end of cooling pipe 10 extends out of the shell and is matched with the heat exchanger) is configured to keep the temperature of the medium in the cooling pipe 2 in a good range all the time, so as to ensure the heat exchange in the shell.

[0024] Specifically, the opening and closing ventilation device 3 includes an induction-type electric louver 301. A metal heat-conducting mesh 304 is provided on the frame of the induction-type electric louver, and the metal heat-conducting mesh 304 is in contact with the cooling pipe 2. Each louver blade of the induction-type electric louver 3 is movably connected to the frame through two rotating shafts 303, and the rotating shafts 303 penetrate through two cross sections of the louver blade. The louver blade can rotate on the rotating shafts 303. There is a certain gap between adjacent louver blades, and adjacent louver blades are connected by a connecting shaft 302. The uppermost or lowermost rotating shaft 303 can be connected to a servo motor for the rotation of the louver blade.

[0025] The above describes how the size of the ventilation openings on both sides is achieved by controlling the angle of the louvers. In fact, electric louvers are a very mature technology in the current field. The above supplement to some structures is only for better explanation and does not point out all the structures. The specific structure is not described in detail.

[0026] To control the induction-type electric louvers 3, a temperature and humidity sensor is installed on the frame. This sensor is connected to the control board inside the charging pile via wires to control the opening and closing of the louvers based on external temperature and humidity data. Specifically, after monitoring the external environment, the temperature and humidity sensor feeds back the data to the controller on the control board. The controller then uses preset thresholds to determine the appropriate thresholds and controls the servo motor to perform the opening and closing operation. In addition to opening and closing, multiple thresholds can be set, such as maximum and minimum opening, with multiple intervals between the maximum and minimum, thus achieving precise control. It should be emphasized that the data processing and command issuance processes described above are mature technologies already in use, and therefore will not be elaborated upon further.

The cooling medium is preferably a coolant with antifreeze function, which not only prevents freezing at low temperatures, but also has good thermal conductivity, which can fully conduct heat from different parts of the charging pile. The water pump makes the cooling medium circulate. When the internal components generate too much heat, the cooling medium that has conducted some heat will pass through the cooling pipe 2 exposed at the top of the charging pile (in conjunction with the heat exchanger for heat exchange and cooling) to achieve circulating heat dissipation.

The front and back of the supporting steel 6 present a hollow structure that runs through the body of the supporting steel 6. Several circular screw holes are opened at the lower end of the supporting steel 6.

[0030] Specifically, the several circular screw holes at the bottom of the receiving steel 6 can be four or six, but the number should be more than three to ensure the stability of the shell, in particular, the screw rod 12 structure passing through the circular screw hole at the bottom is in a pointed shape, and an expansion nail is arranged at the lower end of the screw rod 12, through the pointed screw rod 12 and the expansion nail 121, the shell can be more stably fixed on the ground.

[0031] The working principle of the utility model is: through the opening and closing type ventilation device 3, the size of the inlet and outlet of the ventilation device can be controlled, so that the ventilation process is controllable, especially when affected by external environment, adaptive adjustment can be made, such as when it is rainy or heavy humid weather, in order to reduce the influence of humid air on the inside, the opening and closing type ventilation device can be controlled to adjust the size of the inlet and outlet or be closed, to reduce the influence of external environment on the inside as much as possible, and the cooling pipeline 2 filled with cooling medium can absorb internal heat, and the heat exchange device (which can be a micro compressor, etc., specifically, it can be assembled above the shell 1, and the upper end of the cooling pipeline 2 extends out of the shell and is matched with the heat exchanger) is configured to keep the temperature of the medium in the cooling pipeline 2 within an optimal range at all times, ensuring heat exchange inside the shell.

[0032] The above is only the preferred embodiment of the utility model, and it should be pointed out that for ordinary skilled persons in the technical field, some improvements and refinements can be made without departing from the principles of the present invention, and these improvements and refinements should also be considered within the protection scope of the present invention.
