Description

Technical Field

[0002] A charging pile, also known as an electric vehicle charging station or electric vehicle power supply equipment, is a device that provides electric energy to electric vehicles, enabling them to store enough electricity to support their operation. As an important part of the new energy vehicle ecosystem, the number of charging piles in China is increasing day by day with the rapid development of the new energy vehicle industry.

[0003] In order to protect the charging cable, a charging cable storage structure will be installed on the charging pile to neatly store the cable.

[0004] After completing the charging task, the existing charging piles are unable to effectively monitor the surface temperature of the cables stored in the cable storage structure. As a result, when the charging cable of the charging pile performs the charging task again after completing the last charging task and has not been sufficiently cooled down, it is easy to cause heat accumulation in the charging cable and cause the charging cable to overheat. Especially during holidays, when the demand for electric vehicle charging surges, when people successively take out the charging cables with charging plugs that have not been sufficiently cooled down from the cable storage structure for charging, the cables are prone to cause fires due to excessive heating, causing damage to people and property, and posing a major safety hazard.

[0033] Beneficial effect: One or more technical solutions provided in the technical solution of the present invention have at least the following technical effects or advantages: 1. People charge the battery through the charging pile body and loosely coil the charging cable in the charging pile body around the outer periphery of the mounting structure and support the cable through the load-bearing member. When the cable overheats, the heat energy is continuously transferred to the thermal expansion body through the heat-conducting support frame in the load-bearing member. When the surface temperature of the cable placed in the inner cavity of the heat-conducting support frame is greater than the preset value and triggers the thermal expansion of the thermal expansion body, the expanded thermal expansion body drives the sliding structure to move. The sliding structure drives the passive component to move through the driving component. The movement of the two passive components causes the two locking seats to gradually slide out of the side wall of the inner cavity of the heat-conducting support frame. During this process, the two relatively moving locking seats gradually close the top opening of the heat-conducting support frame and lock the cable placed on the load-bearing member, thereby effectively reducing the use of overheated charging cables for charging and improving the safety of charging piles.

[0034] 2. The expanded thermal expansion and contraction body drives the sliding structure to move, and causes the two passive components to move so that the two locking seats gradually move out from the side wall of the inner cavity of the heat-conducting support frame. When the passive component is in the initial state, the end of the locking seat is flush with the side wall of the inner cavity of the heat-conducting support frame, and in the process of gradually closing the top opening of the heat-conducting support frame, it will also synchronously drive the two switch springs in the control unit to contact the resistance wire and trigger the pneumatic unit to open. The pneumatic unit then inputs a continuous airflow into the inner cavity of the input port, and the airflow is then ejected from the air outlet structure on the outer surface of the annular hollow guide plate. The heat generated by the cable is taken away by air convection, thereby reducing the cable temperature, so as to achieve timely cooling and heat dissipation of the overheated cable coiled around the outer periphery of the mounting structure, so that the overheated charging cable can be accelerated to cool the cable when locked, so that the cable surface temperature is quickly reduced to below the preset value, reducing people's waiting time for charging and improving the use efficiency of the charging pile.

[0035] 3. When the thermistor expands and contracts when receiving the heat energy from the overheated cable and gradually expands due to the heat, and triggers the pneumatic unit to open, as the two locking seats gradually move out from the inner cavity side wall of the heat-conducting bearing frame, and when the passive component is in the initial state, the end of the locking seat is flush with the inner cavity side wall of the heat-conducting bearing frame, and in the process of gradually closing the top opening of the heat-conducting bearing frame, the two switch springs in the control unit approach each other, so that the number of turns of the coil between the two switch springs in the resistance wire is reduced, the resistance becomes smaller, and the output power of the heat dissipation fan is also increased, further accelerating the cooling efficiency of the cable, and as the charging cable gradually cools down, the thermistor expands and contracts gradually when it encounters cold, so that the two locking seats gradually retract and the top opening of the heat-conducting bearing frame is opened again, the output power of the heat dissipation fan gradually decreases, and when the two switch springs are not in contact with the resistance wire, the pneumatic unit is triggered to close, so that when the storage mechanism stores the charging cable in the charging pile body, it can synchronously adjust the output power of the pneumatic unit according to the surface temperature of the cable, which improves the cooling efficiency of the cable while helping to reduce energy consumption and reduce operating costs.

[0068] The movable cavity is connected with the horizontal sliding cavity through the corresponding connecting cavity.

[0069] After people charge the battery through the charging pile body 10, they loosely coil the charging cable in the charging pile body 10 around the outer periphery of the mounting structure and support the cable through the load-bearing member. When the cable overheats, the heat energy is continuously transferred to the thermal expansion body 213 through the heat-conducting support frame 204 in the load-bearing member. When the surface temperature of the cable placed in the inner cavity of the heat-conducting support frame 204 is greater than the preset value and triggers the thermal expansion body 213 to expand due to heat, the expanded thermal expansion body 213 drives the sliding structure to move.

[0079] The expanded thermal expansion and contraction body 213 drives the sliding structure to move, and causes the two passive components to move so that the two locking seats 205 gradually move out from the inner cavity side wall of the heat-conducting support frame 204. When the passive components are in the initial state, the ends of the locking seats 205 are flush with the inner cavity side wall of the heat-conducting support frame 204, and in the process of gradually closing the top opening of the heat-conducting support frame 204, the two switch springs 216 in the control unit are synchronously driven to contact the resistance wire 214, and trigger the cooling fan 207 in the pneumatic unit to turn on, and then the pneumatic unit inputs a continuous airflow into the inner cavity of the input port 206, and the airflow is then ejected from the air outlet structure on the outer surface of the annular hollow guide plate 203, and the heat generated by the cable is taken away by air convection, thereby reducing the cable temperature, so as to achieve timely cooling and heat dissipation treatment of the overheated cable coiled around the outer periphery of the mounting structure, so that the overheated charging cable can be accelerated to cool the cable when locked, so that the cable surface temperature is quickly reduced to below the preset value, reducing people's waiting time for charging and improving the use efficiency of the charging pile.
