The plate body 411 extends from the inside of the space interlayer 111 through the space where the internal charging component 12 is located, and the plate body part in the space of the internal charging component 12 is arranged in a multi-layer shape. The number of turns of the electromagnetic induction coil 1421 is set according to actual needs, and is in the same straight line as the heat pipe 141, and is arranged adjacent to the open port of the heat pipe 141. A hydraulic ring plate 15 is sealed and slidably arranged on the opposite side of the separating ring plate 14 inside the space interlayer 111. A spring limiting rod 151 and a switch push rod 152 are fixedly arranged on the annular surface of the hydraulic ring plate 15 facing the separating ring plate 14 corresponding to the heat pipe 141 and the plug-in switch 142, wherein the spring limiting rod 151 is composed of a T-shaped rod and a spring fixed to the end of the T-shaped rod, and the T-shaped rod is After passing through the electromagnetic induction coil 1421, it is confined inside the auxiliary heat plate 1411 by sliding through the spring. The switch push rod 152 can dock with the switch of the plug-in switch 142 under the push of the separation ring plate 14 to open and close the plug-in switch 142. The interior of the space interlayer 111 is filled with heat expansion liquid in the closed space isolated by the hydraulic ring plate 15, and the liquid is in contact with the environmental heat conduction plate group 112. The environmental heat conduction plate group 112 is composed of a plurality of heat conducting plates, and extends from the interior of the space interlayer 111 through the charging pile box 11 to the outside of the charging pile box 11, and the heat expansion liquid exchanges heat with the external environment through the environmental heat conduction plate group 112.

[0033] When the charging pile is in use, if it is summer, the environmental heat conduction plate group 112 is affected by the heat of the external high temperature environment, and the heat of the external environment will be transferred to the heat expansion liquid stored in the space interlayer 111, and then the heat expansion liquid will expand due to the heat, and push the hydraulic ring plate 15 to slide along the inner wall of the space interlayer 111 toward the direction of the separation ring plate 14, and during the sliding process of the hydraulic ring plate 15, the spring limiting rod 151 and the switch push rod 152 on its surface will be driven to move synchronously, wherein the spring limiting rod 151 will move along the heat conduction pipe 141 to compress the spring, and the switch push rod 152 will gradually move toward the plug-in switch 142.

At this time, the plug-in switch 142 is closed, the plug-in switch 142 and the internal charging component 12 are in a disconnected state, and the electromagnetic induction coil 1421 does not work. If it is winter, the environmental heat conduction plate group 112 is affected by the external low temperature environment, and the environmental heat conduction plate group 112 will absorb heat from the heat expansion liquid stored in the space interlayer 111. At this time, due to the low thermal expansion force of the heat expansion liquid, the spring limiting rod 151 will be gradually moved out of the heat conduction pipe 141 under the action of the spring, and push the hydraulic ring plate 15 away from the heat conduction pipe 141. The separation ring plate 14 moves in the direction of the separation ring plate 14, and the storage space of the heat-expanding liquid will be gradually compressed. At the same time, with the movement of the hydraulic ring plate 15, the switch push rod 152 will gradually break away from the pressing state on the switch button of the plug-in switch 142, and then the plug-in switch 142 will re-energize the electromagnetic induction coil 1421 and the internal charging component 12, and the energized electromagnetic induction coil 1421 will generate a magnetic field, and the magnetic field will guide the movement of electrons inside the spring limiting rod 151 inserted therein and generate eddy currents, and then the rod body of the spring limiting rod 151 within the range of the electromagnetic induction coil 1421 will be heated, and then the heat will be transferred along the The spring limiting rod 151 conducts heat to the heat pipe 141 and the auxiliary heat plate 1411, wherein the auxiliary heat plate 1411 will directly diffuse the heat into the space where the internal charging component 12 is located, and the heat pipe 141 will conduct and diffuse the heat to the heat-conducting material filled in the space interlayer 111, and then conduct the heat to the inside of the heat sink group 132 through the heat-conducting material, and finally conduct and diffuse to the space where the internal charging component 12 is located through the heat sink group 132 and the built-in heat sink 13. At the same time, it can also prevent the internal heat of the internal charging component 12 from being lost to the outside too quickly through the heat sink group 132, thereby ensuring the winter insulation effect.

[0034] To sum up, through the arrangement of the charging pile box 11, the space interlayer 111, the environmental heat conduction plate group 112, the built-in heat sink 13, the heat sink group 132, the separation ring plate 14, the heat conduction pipe 141, the auxiliary heat plate 1411, the plug-in switch 142, the electromagnetic induction coil 1421, the hydraulic ring plate 15, the spring limiting rod 151 and the switch push rod 152, the hydraulic ring plate 15 can be driven to move back and forth according to the temperature of the external environment in combination with the thermal expansion material and the spring limiting rod 151, and thereby drive the switch push rod 152 to open and close the plug-in switch 142 in a pushing and plugging manner, thereby controlling the on and off of the circuit between the internal charging component 12 and the electromagnetic induction coil 1421, and achieving an automatic heating and insulation working mode of stopping in summer and starting in winter, ensuring that the charging pile can also have a stable charging efficiency in winter, and can meet the charging needs of cars in different environments and different regions, thereby enhancing the owner's experience of using electric vehicles.

The emergency stop switch 121 is fixedly arranged on the side of the charging pile box 11 and has a manually touchable knob. The piston rod of the screw piston push rod 1313 extends out of the liquid pipe 131 and presses on the surface of the screw nut that fixes the circuit.

A module for information display is arranged inside the front display cover plate 2, and the information display module is electrically connected to the internal charging component 12 through a line. A through hole is provided on the surface of the internal charging component 12, and a water droplet transparent end 1311 of the liquid tube 131 extends and is inserted into the inside of the through hole, and the water droplet transparent end 1311 protrudes from the surface of the internal charging component 12 in the form of a hemisphere.

[0037] During the use of the charging pile, if the screws fixing the circuit inside the internal charging component 12 are displaced due to thread withdrawal, the screws will directly feed back the displacement to the screw piston push rod 1313, and the screw piston push rod 1313 will push the liquid inside the liquid tube 131 to flow into the water drop transparent end 1311 through the piston, and compress the first spring 1312. The liquid entering the water drop transparent end 1311 will be directly displayed on the surface of the front display cover 2 through its own color, and then the user or maintenance personnel can use the information provided by the water drop transparent end 1311 on the surface of the front display cover 2 to promptly locate the circuit connection points with short circuit risks and quickly carry out repairs and maintenance.

[0038] To summarize, by arranging the liquid pipe 131, the water drop transparent end 1311, the first spring 1312 and the screw piston push rod 1313 at the line connection position of the internal charging component 12, the screw piston push rod 1313 can be used to drive the liquid to flow inside the liquid pipe 131 and fill the water drop transparent end 1311 according to the feedback of the screw withdrawal displacement, and the liquid's own color can be used to make the water drop transparent end 1311 filled with liquid directly displayed on the surface of the front display cover 2 in a more eye-catching color, which can not only provide danger reminders for users and facilitate users to contact maintenance personnel in time for necessary maintenance, but also assist maintenance personnel to quickly locate the location where there is a risk of short circuit or fire, greatly improving the convenience of charging pile maintenance and improving the efficiency of charging pile maintenance.

At this time, due to the low thermal expansion force of the thermal expansion liquid, the spring limiting rod 151 will gradually move out of the heat pipe 141 under the action of the spring, and push the hydraulic ring plate 15 to move away from the separation ring plate 14, and the storage space of the thermal expansion liquid will be gradually compressed. At the same time, with the movement of the hydraulic ring plate 15, the switch push rod 152 will gradually break away from the top pressure state on the switch button of the plug-in switch 142, and then the plug-in switch 142 will re-energize the electromagnetic induction coil 1421 and the internal charging component 12, and the energized electromagnetic induction coil 1421 will generate a magnetic field, and the magnetic field will guide the movement of electrons inside the spring limiting rod 151 inserted therein, and generate eddy currents, and then the spring The rod body of the limiting rod 151 within the range of the electromagnetic induction coil 1421 will be heated, and then the heat will be conducted along the spring limiting rod 151 to the heat pipe 141 and the auxiliary heat plate 1411, wherein the auxiliary heat plate 1411 will directly diffuse the heat into the space where the internal charging component 12 is located, and the heat pipe 141 will conduct and diffuse the heat to the inside of the heat-conducting material filled in the space interlayer 111, and then conduct the heat to the inside of the heat dissipation plate group 132 through the heat-conducting material, and finally conduct and diffuse to the space where the internal charging component 12 is located through the heat dissipation plate group 132 and the built-in heat dissipation plate 13.
