Description

Technical Field

[0001] The present invention relates to the technical field of charging piles, and in particular to a convenient mobile charging pile. Background Art

[0002] The function of a charging pile is similar to that of a gas pump in a gas station. It can be fixed on the ground or on a wall and installed in public buildings (such as public buildings, shopping malls, public parking lots, etc.) and parking lots or charging stations in residential areas. The input end of the charging pile is directly connected to the AC power grid, and the output end is equipped with a charging plug to provide charging services for electric vehicles. Charging piles generally provide two charging methods: conventional charging and fast charging. Users can use a specific charging card to swipe the card on the human-computer interaction interface provided by the charging pile to perform corresponding operations such as charging method, charging time, and cost data printing. The charging pile display can also display data such as charging amount, cost, and charging time.

[0003] Most of the existing charging piles are fixed at specific locations and cannot meet the charging needs in different environments. However, the existing movable charging piles still have the following problems in actual use:

[0004] Patent No. "CN201721740754.6" discloses a movable charging pile. When in use, the charging pile can be moved through the improvement of the device body and the coordinated use of the display screen, control panel, card reader, output interface and input interface, thereby expanding the use range of the charging pile, meeting the user's use needs well, improving work efficiency and facilitating user use. During use, the device cannot be rainproof on rainy days, and the rain usually contains sulfides, metal particles, dust, etc., which will corrode the charging pile body during long-term use, resulting in a significant reduction in service life.

[0005] A Chinese patent discloses a mobile charging pile (authorization announcement number CN222451975U). The patented technology is provided with a rain shielding mechanism, which is used to shield the device from rain during use, so as to prevent the device from being corroded by rain during long-term use, thereby preventing the service life from being shortened. The cooling mechanism provided can cool the charging pile body when the device is heated during use, so as to prevent the battery from being overheated for a long time and reducing its service life; the air flow inside the charging pile body is circulated through the filter, so as to prevent dust and impurities in the external air from entering the charging pile body;

[0006] However, it has certain disadvantages: although the rain shield mechanism can prevent rain from directly impacting the charging pile body, in extreme weather or when the wind direction changes, rainwater may still bypass the rain shield mechanism and directly contact the charging pile body, and then enter the interior of the charging pile body through the filter, causing a short circuit inside the charging pile body or aging of components.

During use, the control system controls the fan 8 to start the heat dissipation treatment of the inside of the charging pile body 1, and the filter plate 7 prevents external dust and impurities from entering the inside of the charging pile body 1. When it rains, the rain shield 6 protects the charging pile body 1. After rain drops on the rain sensor 14, the rain sensor 14 transmits the sensing signal to the external control system, and the external control system first controls The fan 8 stops running, and then controls the first motor 19 and the second motor 25 to operate successively.
