[0002] A charging terminal includes a charging gun and a power distribution component connected to the charging gun. Common charging piles usually have only one, which results in low charging efficiency. Furthermore, the power distribution component inside the charging pile generates a lot of heat during the charging process, especially when the temperature is high. If the temperature inside the charging pile is not cooled in time, it can easily lead to malfunction of the power distribution component inside the charging pile, affecting the service life of the component and requiring frequent replacement.

[0003] Therefore, in response to the above-mentioned technical problems, a dual-gun fast charging station is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a dual-gun fast charging station, which solves the problems mentioned in the background art by setting up an air inlet, an air outlet, a cooler, a temperature sensor and an alarm.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dual-gun fast charging pile, comprising a charging terminal, the charging terminal including a charging pile body, secondary equipment, a control unit, a human-machine interface, two charging guns and two gun bases, the two gun bases being symmetrically arranged on both sides of the charging pile body, the charging guns being mountable on the gun bases, the lower ends of the charging guns being connected to the charging pile body via charging cables, the two sides of the charging pile body being provided with air inlets and air outlets respectively below the gun bases, the air inlets and air outlets being arranged opposite to each other, a cooling fan being provided above the air inlet, one end of the cooling fan extending into the charging pile body;

[0006] The human-machine interface is located on the front of the charging terminal, and the secondary device is located in the middle part of the inner cavity of the charging terminal. The secondary device includes a temperature sensor and an alarm. The temperature sensor and the alarm are interconnected and electrically connected to the human-machine interface.

[0007] As a preferred embodiment, filters are provided at the air inlet and air outlet.

The door is fixedly installed on the front of the charging terminal, the sheet metal accessories are fixedly welded to the charging terminal, and the door lock is installed on the side of the charging terminal.

[0009] As a preferred embodiment, the secondary equipment further includes a contactor, a fuse, a shunt, and a limit switch, wherein the contactor, fuse, shunt, and limit switch are respectively disposed in the middle part of the charging terminal's internal cavity.

[0010] As a preferred embodiment, the control unit includes a main control board, a gun line control board, a lamp board, an auxiliary power supply, and an emergency stop button. The main control board, the gun line control board, and the lamp board are located above the secondary equipment. The auxiliary power supply is located in the lower part of the charging terminal body, and the emergency stop button is located directly above the gun base.

[0011] As a preferred embodiment, the charging terminal is also equipped with a cooling fan and a water immersion sensor.

[0035] 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 embodiments.

[0036] like Figure 1-5 As shown, this utility model embodiment provides a dual-gun fast charging pile, including a charging terminal 100. The charging terminal 100 includes a charging pile body 110, a secondary device 120, a control unit 130, a human-machine interface 160, two charging guns 170, and two gun holders 180. The two gun holders 180 are symmetrically arranged on both sides of the charging pile body 110. The charging guns 170 can be installed on the gun holders 180. The lower ends of the charging guns 170 are connected to the charging pile body 110 through charging cables. The two sides of the charging pile body 110, located below the gun holders 180, are respectively provided with air inlets 114 and air outlets 115. The air inlets 114 and air outlets 115 are arranged opposite to each other. A cooler 117 is provided above the air inlet 114, and one end of the cooler 117 extends into the charging pile body 110.

[0037] The human-machine interface 160 is located on the front of the charging terminal 110, and the secondary device 120 is located in the middle part of the inner cavity of the charging terminal 110. The secondary device 120 includes a temperature sensor 125 and an alarm 126. The temperature sensor 125 and the alarm 126 are interconnected and electrically connected to the human-machine interface 160.

[0038] The charging terminal 110 is equipped with symmetrical gun holders 180 on both sides, and charging guns 170 are installed on the two gun holders 180. The lower ends of the charging guns 170 are connected to the charging terminal 110 via charging cables. With two charging guns 170 on one charging terminal 110, two devices can be charged simultaneously, improving the charging efficiency. Air inlets 114 and air outlets 115 are respectively located on both sides of the charging terminal 110 below the gun holders 180, facing each other. A cooler 117 is installed above the air inlet 114. The temperature sensor 118 and alarm 119 in the secondary equipment 120 are interconnected and electrically connected to the human-machine interface 170. When the charging terminal is working, the temperature sensor 118 monitors the temperature inside the terminal. Temperature monitoring is used. When the temperature inside the charging pile does not exceed the preset temperature, heat dissipation is achieved solely through the air inlet 114 and air outlet 115. Since the air inlet 114 and air outlet 15 are positioned opposite each other, convection is generated within the charging pile 110, which carries the heat generated by the power distribution components inside the pile out of the pile. When the temperature sensor 118 detects that the temperature inside the pile exceeds the preset temperature, the alarm 119 sounds an alarm and transmits the information to the human-machine interface 170 for alarm display. Subsequently, the air cooler 117 is turned on to cool the air outside the pile and send it into the inner cavity of the pile, quickly cooling the power distribution components inside the pile to prevent the temperature inside the pile from becoming too high. Through the above device settings, the corresponding cooling method can be selected according to the temperature inside the pile, saving energy while cooling the power distribution components.

[0039] like Figure 4 As shown, filters 116 are provided at the air inlet 114 and the air outlet 115.

[0040] Among them, filters 116 are installed in the air inlet 114 and the air outlet 115, which can prevent external dust from entering the charging terminal 110 when convection is generated inside the charging terminal 110.

[0041] like Figure 4 As shown, the charging terminal 100 includes a door 111, a sheet metal accessory 112, and a door lock 113. The door 111 is fixedly installed on the front of the charging terminal 100, the sheet metal accessory 112 is fixedly welded to the charging terminal 110, and the door lock 113 is installed on the side of the charging terminal 100.

[0042] The door 111 can be fixed to the charging terminal 110 by means of a link or other means. The sheet metal accessory 112 can be set on the charging terminal 110 by welding or bolting. The door lock 113 is set on the side of the charging terminal 100, reducing the number of components on the front door and giving it a simple and elegant appearance.

[0043] like Figure 5 As shown, the secondary equipment 120 also includes a contactor 121, a fuse 122, a shunt 123, and a limit switch 124. The contactor 121, fuse 122, shunt 123, and limit switch 124 are respectively disposed in the middle part of the inner cavity of the charging terminal 110.

[0044] Among them, the contactor 121, fuse 122, shunt 123 and limit switch 124 in the secondary equipment 120 are centrally located in the middle part of the inner cavity of the charging terminal 110. The internal components are arranged in a reasonable manner and the wiring is convenient, which facilitates the early installation and later maintenance of the components.

[0045] like Figure 3 As shown, the control unit 130 includes a main control board 131, a gun line control board 132, a lamp board 133, an auxiliary power supply 134, and an emergency stop button 135. The main control board 131, the gun line control board 132, and the lamp board 133 are located above the secondary equipment 120. The auxiliary power supply 134 is located in the lower part of the charging terminal 110. The emergency stop button 135 is located directly above the gun base 180.

[0046] The main control board 131, the gun line control board 132, and the lamp board 133 are located above the secondary equipment 120, with reasonable internal component arrangement and convenient wiring, facilitating the early installation and later maintenance of the components. The auxiliary power supply 134 is located in the lower part of the charging terminal 110, increasing the distance between the auxiliary power supply 134 and other components, reducing the impact of the auxiliary power supply 134's heat on other components. The emergency stop button 135 is located directly above the gun base 180, further reducing the number of components on the front cabinet door.

[0047] like Figure 3 As shown, the charging terminal 100 is also equipped with a cooling fan 140 and a water immersion sensor 150. The cooling fan 140 is located on the side wall of the inner cavity of the charging terminal 100 facing the auxiliary power supply 134. The water immersion sensor 150 is located at the bottom of the inner cavity of the charging terminal 100 and is connected to the alarm 119.

[0048] The cooling fan 140 is installed on the side wall of the charging terminal 100 cavity facing the auxiliary power supply 134 to facilitate heat dissipation. The water immersion sensor 150 is installed at the bottom of the charging terminal 100 cavity. The function of the water immersion sensor 150 is to detect whether water leakage occurs in the monitored area. Once water leakage is detected, the alarm 119 will immediately sound an alarm to prevent water leakage accidents from causing related losses and hazards.

[0049] like Figure 4 As shown, a drainage groove 190 is provided below the gun base 180, and the upper end of the drainage groove 190 is connected to the gun base 180.

[0050] A drainage trough 190 is provided below the gun base 180 to prevent water from accumulating on the gun base 180 during rain, thus affecting the use of the charging station.

[0051] The working principle of this embodiment is as follows: Temperature sensor 118 monitors the temperature inside the pile. When the temperature inside the pile does not exceed the preset temperature, heat dissipation is achieved solely through air inlet 114 and air outlet 115. Since air inlet 114 and air outlet 15 are arranged opposite each other, convection is generated inside the charging pile 110, which can carry the heat generated by the power distribution components inside the pile out of the pile. When temperature sensor 118 detects that the temperature inside the pile exceeds the preset temperature, alarm 119 sounds an alarm and transmits the information to the human-machine interface 170 for alarm display. Then, the air cooler 117 is turned on to cool the air outside the pile and send it into the inner cavity of the pile, quickly cooling the power distribution components inside the pile to prevent the temperature inside the pile from becoming too high. Through the above device settings, the corresponding cooling method can be selected according to the temperature inside the pile, saving energy while cooling the power distribution components.

[0052] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
