Description

Technical Field

[0001] The utility model relates to the technical field of charging equipment, in particular to an integrated direct current charging pile. Background Art

[0002] The integrated DC charging pile is a charging device designed for the charging needs of electric vehicles. It uses a DC charging method and can convert 380V power into a high-current DC charging voltage through a transformer, providing efficient and fast charging services for electric vehicles. At present, the integrated DC charging pile usually consists of two parts: the charging pile body and the charging gun.

[0003] At present, a Chinese patent discloses an integrated DC charging pile (publication number CN216424122U), which can well define the position of the charging gun to prevent it from falling from the placement box and causing damage, and can also well shield the main body to prevent it from being damaged by rain and the like.

[0004] Since the rainproof structure adopted by the above-mentioned device can only block rain on the main body of the charging pile and cannot cover the charging gun, when the user moves the charging gun on a rainy day, rain will inevitably fall on the gun head of the charging gun. After the gun head of the charging gun is wet and the user puts the charging gun into the placement box, the water will still remain at the gun head of the charging gun, which will not only increase the probability of a short circuit in the charging gun, but also increase the risk of subsequent charging, posing a major safety hazard.

[0005] Therefore, an integrated DC charging pile is proposed to solve the above problems. Utility Model Content

[0008] Preferably, the dehumidification mechanism includes a fan, an air duct, a pressure switch and a first exhaust pipe, the fan is fixedly connected to the interior of the charging pile body, the air duct is connected to one end of the fan, the top of the air duct is fixedly connected and connected to the bottom of the socket, the pressure switch is fixedly connected to the interior of the socket, one end of the pressure switch is in contact with the charging gun, and the first exhaust pipe is fixedly connected and connected to the top of the socket. The dehumidification mechanism can not only automatically dehumidify the charging gun after the charging gun is put back, but also dissipate heat from the interior of the charging pile body when not performing dehumidification, thereby reducing the use cost of the dehumidification mechanism.

[0009] Preferably, the axial center lines of the air guide pipe and the first exhaust pipe are staggered, and the air guide pipe and the first exhaust pipe are respectively arranged on both sides of the charging gun, which can extend the area of ​​the airflow drying the end of the charging gun and further improve the drying effect on the end of the charging gun.

[0010] Preferably, the bottom of the first exhaust pipe is fixedly connected and communicated with a one-way valve, and the blocking direction of the one-way valve is the same as the direction from the first exhaust pipe to the socket, which can prevent external moisture, dust and other impurities from entering the socket through the first exhaust pipe to ensure the cleanliness of the inside of the socket.

[0011] Preferably, the other end of the air duct is fixedly connected to a three-way solenoid valve connected to the fan, and the three-way solenoid valve is fixedly connected to the surface of the charging pile body; the other end of the three-way solenoid valve is fixedly connected and connected to a second exhaust pipe, and the opening of the second exhaust pipe faces downward, which enables the fan to dissipate heat to the interior of the charging pile body when not performing dehumidification operations, thereby reducing the use cost of the dehumidification mechanism.

[0013] Preferably, the surface of the ring is fixedly connected with air guide plates distributed in a ring shape around the axis of the ring. At this time, the two air guide plates that are horizontal and opposite to each other coincide with the axis of the air guide pipe and the first exhaust pipe respectively, which can increase the contact area between the cleaning mechanism as a whole and the airflow, thereby improving the cleaning efficiency of the cleaning mechanism.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] When implementing: Figure 1-5As shown, an integrated DC charging pile includes: a charging pile body 1, a charging gun 2 is installed on the surface of the charging pile body 1, and a rain shelter 3 is fixedly connected to the top of the charging pile body 1; a protective device 4, the protective device 4 is installed on the surface of the charging pile body 1, and one end of the charging gun 2 is plugged into the protective device 4; the protective device 4 includes a socket 41 fixedly connected to the surface of the charging pile body 1, one end of the charging gun 2 is plugged into the socket 41, a dehumidification mechanism 42 is installed on the surface of the socket 41, one end of the dehumidification mechanism 42 passes through the socket 41 and extends to the interior of the charging pile body 1, and a cleaning mechanism 43 is rotatably connected to the interior of the socket 41.

[0025] like Figure 3 , Figure 4 and Figure 5 As shown, the dehumidification mechanism 42 includes a fan 421, an air duct 422, a pressure switch 423 and a first exhaust pipe 424. The fan 421 is fixedly connected to the inside of the charging pile body 1, the air duct 422 is connected to one end of the fan 421, the top of the air duct 422 is fixedly connected and connected to the bottom of the socket 41, the pressure switch 423 is fixedly connected to the inside of the socket 41, one end of the pressure switch 423 is in contact with the charging gun 2, the first exhaust pipe 424 is fixedly connected and connected to the top of the socket 41, and the fan 421 is fixedly connected to the inside of the charging pile body 1, the air duct 422 is connected to one end of the fan 421, the top of the air duct 422 is fixedly connected and connected to the bottom of the socket 41, the pressure switch 423 is fixedly connected to the inside of the socket 41, one end of the pressure switch 423 is in contact with the charging gun 2, and the first exhaust pipe 424 is fixedly connected and connected to the top of the socket 41. The fan 421 can replace the original air-cooled heat dissipation structure inside the charging pile body 1. At this time, the fan 421 needs to be in a normally open state and is no longer connected to the pressure switch 423. When the pressure switch 423 is not triggered, the three-way solenoid valve 426 connects the fan 421 with the second exhaust pipe 427. The fan 421 quickly circulates the air inside the charging pile body 1 through the three-way solenoid valve 426 and the second exhaust pipe 427, so that the electrical components inside the charging pile body 1 are cooled; at the same time, a fixed pressure switch 423 is provided inside. When the pressure switch 423 is squeezed and triggered, the timer is also started. When the preset countdown of the timer ends, the timer feeds back the corresponding signal to the pressure switch 423. The pressure switch 423 controls the three-way solenoid valve 426 according to the preset instruction corresponding to the signal to reconnect the fan 421 with the second exhaust pipe 427, so that the socket 41 no longer takes in air, so as to reduce the impact on the charging gun 2; the axis lines of the air guide pipe 422 and the first exhaust pipe 424 are staggered, and the air guide pipe 422 and the first exhaust pipe 424 are staggered. 24 are respectively arranged on both sides of the charging gun 2; the bottom of the first exhaust pipe 424 is fixedly connected and communicated with a one-way valve 425, and the blocking direction of the one-way valve 425 is the same as the direction from the first exhaust pipe 424 to the socket 41; the other end of the air guide pipe 422 is fixedly connected to a three-way solenoid valve 426 communicated with the fan 421, and the three-way solenoid valve 426 is fixedly connected to the surface of the charging pile body 1; the other end of the three-way solenoid valve 426 is fixedly connected and communicated with a second exhaust pipe 427, and the opening of the second exhaust pipe 427 faces downward.

[0026] like Figure 4As shown, the cleaning mechanism 43 includes a ring 431 rotatably connected to the inside of the socket 41, and a flexible brush 432 is fixedly connected to the inner side of the ring 431 and is distributed in a ring shape around the axis of the ring 431, and one end of the flexible brush 432 is in contact with the charging gun 2; the surface of the ring 431 is fixedly connected to an air guide plate 433 distributed in a ring shape around the axis of the ring 431, and at this time, the two air guide plates 433 in a horizontal state and opposite to each other coincide with the axis of the air guide pipe 422 and the first exhaust pipe 424 respectively;

[0027] When the airflow passes through the inside of the socket 41 , the airflow inevitably impacts the air guide piece 433 . The air guide piece 433 drives the ring 431 to rotate. The ring 431 drives the flexible brush 432 to rotate and brush away dust, water droplets and other impurities on the surface of the charging gun 2 , thereby further ensuring the cleanliness of the charging gun 2 .

[0028] When the utility model is in use, when the user inserts the charging gun 2 into the socket 41 and plugs the charging gun 2 into place, the charging gun 2 squeezes and triggers the pressure switch 423, and the pressure switch 423 simultaneously turns on the fan 421 and controls the three-way solenoid valve 426 to connect the fan 421 with the air duct 422. At this time, the fan 421 stirs the hot air inside the charging pile body 1 and transports the hot air into the air duct 422 through the three-way solenoid valve 426. The air duct 422 guides the hot air into the inside of the socket 41, and the hot air flows into the first exhaust pipe 424 along the gap between the socket 41 and the charging gun 2. If there is water or dust on the surface of the charging gun 2, the hot air can quickly evaporate the water into water vapor, and then the water vapor and dust are entrained into the first exhaust pipe 424, which can keep the end of the charging gun 2 clean and dry at all times, thereby reducing the problem of short circuit of the charging gun 2 due to water in the future, thereby reducing the safety hazard of the use of the charging gun 2.

[0029] It should be noted that the charging pile body 1, charging gun 2, fan 421, pressure switch 423, three-way solenoid valve 426 and timer in the above description are all relatively mature devices in the existing technology. The specific models can be selected according to actual needs. At the same time, the fan 421, pressure switch 423, three-way solenoid valve 426 and timer can be powered by a built-in power supply or by AC power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0030] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
