[0033] The outer wall of the bottom end of the outdoor energy storage power supply device main body 1 is fixedly connected with two positioning ropes 18. The side ends of the two positioning ropes 18 are commonly fixedly connected with a fixed bottom plate 19. The upper surface of the fixed bottom plate 19 is fixedly connected with a parking mechanism 8 for blocking the wheels.

The mechanism can correct the parking posture of the new energy vehicle in the charging parking space, avoid the vehicle body from tilting and interfering with the parking of other vehicles in the surrounding charging parking spaces, and protect the outdoor energy storage power supply device main body 1.

[0034] The temperature sensor 4 and the two air pressure sensors 82 are electrically connected to the input end of the microcontroller 15 through wires, the three-way reversing electromagnetic valve 66, the double-control switch 67, the semiconductor refrigeration piece 72, the electric heating pipe 75, the air pump 76 and the normally open electromagnetic valve 79 are electrically connected to the output end of the microcontroller 15, and the loudspeaker 16 and the storage 17 are also electrically connected to the microcontroller 15, the model of the microcontroller 15 is Arduino Uno controller, and the above-mentioned power-on devices and electrical connections are prior art, which will not be described here.

[0035] The operation principle of the application is described as follows: when the new energy vehicle needs to be quickly charged by the outdoor energy storage power supply device, the driver first parks the new energy vehicle in the charging parking space, then the fixed bottom plate 19 and the car stopping hollow block 81 arranged in front of the main body 1 of the outdoor energy storage power supply device can avoid the new energy vehicle from being too close to cause a collision accident, at the same time, if the new energy vehicle parked in the charging parking space is inclined and easily interferes with the parking of other new energy vehicles in the surrounding charging parking spaces, since the new energy vehicle is inclined, only one rear wheel of the new energy vehicle will press the arc-shaped rubber cover 84 on the car stopping hollow block 81, the arc-shaped rubber cover 84 deforms to make the air inside it enter the car stopping hollow block 81 through the air hole 83 and increase the air pressure in the car stopping hollow block 81, the air pressure sensor 82 sends the pressure data to the microcontroller 15, and when the air pressure detected by the air pressure sensor 82 reaches the preset air pressure threshold value of the microcontroller 15, the microcontroller 15 plays the pre-stored vehicle posture adjustment reminder voice information in the storage 17 through the loudspeaker 16 to remind the driver to adjust the posture of the new energy vehicle in time, and make the two rear wheels of the new energy vehicle close to the parking mechanism 8, so as to avoid the situation that the new energy vehicle is far away from the parking mechanism 8, causing the charging port of the new energy vehicle to be too far away from the charging plug 2 and unable to be charged, in addition, when the new energy vehicle approaches the parking mechanism 8 in a correct posture, the two rear wheels of the new energy vehicle simultaneously affect the air pressure sensors 82 in the two car stopping hollow blocks 81, and then send electric signals to the microcontroller 15, at this time, the microcontroller 15 does not control the loudspeaker 16 to play the pre-stored vehicle posture adjustment reminder voice information in the storage 17, then the driver gets off the vehicle and performs the quick charging operation on the new energy vehicle through the outdoor energy storage power supply device main body 1 and the charging plug 2.

[0036] When the driver takes out the charging plug 2 from the outdoor energy storage power supply device main body 1 to charge the new energy vehicle, at this time the driver needs to press the limiting button on the charging plug 2 to unlock and conveniently take out the charging plug 2, and at the same time the driver presses the double control switch 67. After pressing one of the switch buttons of the double control switch 67, the double control switch 67 circuit sends an electrical signal to the input end of the microcontroller 15. The microcontroller 15 plays the voice information stored in the storage 17 according to the signal to remind the driver to wipe off the impurities and water stains attached to the surface of the charging plug 2, so as to avoid the impurities entering the charging port to cause poor contact, and the water stains causing short circuit at the charging interface. The mechanism makes the outdoor energy storage power supply device have the functions of voice broadcast reminding of wiping off the attachments on the surface of the charging plug 2 and improper parking posture of the new energy vehicle, and improves the reliability and safety of the outdoor energy storage power supply device for charging the new energy vehicle.

[0037] When the charging plug 2 is inserted into the charging interface of the new energy vehicle, first, the negative pressure suction cup 65 contacts the surface of the new energy vehicle, and then the staff needs to press the limiting button of the charging plug 2 again, so that the charging plug 2 can be smoothly inserted into the charging interface of the new energy vehicle. During the pressing of the limiting button, the driver will press the other switch button of the double control switch 67 at the same time. Then the switch button sends an electrical signal to the microcontroller 15 through the double control switch 67. The microcontroller 15 energizes the three-way reversing electromagnetic valve 66 and the air suction pump 76 for 10 seconds according to the electrical signal. During the 10 seconds, the air suction pump 76 sucks the air in the guide cylinder 62 through the air suction pipe 77, the guide cylinder 62 sucks the air in the negative pressure suction cup 65 through the moving pipe 63, so that the negative pressure suction cup 65 is tightly adsorbed on the surface of the new energy vehicle. Moreover, after the air in the guide cylinder is sucked out, the moving pipe 63 will try to contract, so as to ensure that the limiting mechanism 6 can assist in supporting the charging plug 2, so that the charging plug 2 has two-point position common support when charging the new energy vehicle, avoiding the whole weight of the charging plug 2 acting on the charging interface of the new energy vehicle, further avoiding the damage of the plug-in end of the charging plug 2 due to its own weight. During the insertion of the charging plug 2, the charging interface of the new energy vehicle pushes the hollow cylinder 51 to move, so that the hollow cylinder 51 carries the sealing moving ring 13 to approach the damping rubber sleeve 11, and the damping rubber sleeve 11 contacts the sealing moving ring 13. The friction between the two can effectively improve the stability of the position of the hollow cylinder 51, and the hollow cylinder 51 can ensure the sealing of the side end through the protection rubber ring 9. The mechanism makes the outdoor energy storage power supply device have the function of auxiliary support, avoids the damage of the plug-in end of the charging plug 2 due to its own weight, and at the same time can improve the stability and safety of the outdoor energy storage power supply device for charging the new energy vehicle.

[0038] When the outdoor energy storage power supply device causes the charging plug 2 to overheat during rapid charging of the new energy vehicle, the temperature sensor 4 detects the internal temperature of the charging plug 2 in real time and sends a temperature electrical signal to the microcontroller 15. If the temperature inside the charging plug 2 exceeds the preset temperature threshold of the microcontroller 15, the microcontroller 15 controls the semiconductor refrigeration sheet 72, the normally open electromagnetic valve 79, and the air suction pump 76 to work. The air suction pump 76 sucks external air through the air suction pipe 77 and the three-way reversing electromagnetic valve 66 that changes the air direction without power. Then the external air enters the heat insulation box 71, and the refrigeration layer of the semiconductor refrigeration sheet 72 reduces the temperature inside the heat insulation box 71 through the metal mesh plate 73, thereby reducing the temperature of the external air input by the air suction pump 76. At this time, the normally open electromagnetic valve 79 is closed due to power-on, and the low-temperature air in the heat insulation box 71 is transported to the hollow cylinder 51 through the air outlet pipe 78. Then the low-temperature air in the hollow cylinder 51 is sprayed to the surface of the charging plug 2 through the one-way air jet nozzle 52 for heat dissipation, and then the heat-dissipated air is discharged through the exhaust one-way valve 53. The low-temperature air can prevent the charging plug 2 from continuously overheating, and the charging plug 2 does not need to adjust the current through the charging plug 2 in the outdoor energy storage power supply device through the thermal management chip, thereby ensuring that the outdoor energy storage power supply device can continuously and rapidly charge the new energy vehicle.

[0039] If the new energy vehicle is charged in a low-temperature environment, especially when the charging plug 2 is not pulled out after charging, the temperature sensor 4 sends a low-temperature electrical signal to the microcontroller 15. If the temperature is lower than the preset low-temperature threshold of the microcontroller 15, the microcontroller 15 controls the electric heating pipe 75, the normally open electromagnetic valve 79, and the air suction pump 76 to work. The air suction pump 76 sucks external air through the air suction pipe 77 and the three-way reversing electromagnetic valve 66 that changes the air direction without power. Then the external air enters the heat insulation box 71, and the electric heating pipe 75 can increase the temperature inside the heat insulation box 71 through the metal mesh plate 73 after being powered on, thereby increasing the temperature of the external air input by the air suction pump 76. At this time, the normally open electromagnetic valve 79 is closed due to power-on, and the hot air in the heat insulation box 71 is transported to the hollow cylinder 51 through the air outlet pipe 78. Then the hot air in the hollow cylinder 51 is sprayed to the surface of the charging plug 2 through the one-way air jet nozzle 52 for heating, and then the heated air is discharged through the exhaust one-way valve 53, thereby further increasing the temperature near the charging plug 2, avoiding the condensation of water in the air into ice on the surface of the charging plug 2 in a low-temperature environment, and avoiding the situation that the charging plug 2 is frozen and not easy to pull out. This mechanism enables the charging plug 2 of the outdoor energy storage power supply device to have a cold and hot automatic adjustment function, and improves the protection capability of the charging plug 2 of the device. Not only can it avoid the situation that the charging plug 2 continuously overheats and reduces the charging efficiency, but also can avoid the situation that the charging plug 2 is frozen in a low-temperature environment, thereby ensuring the charging efficiency of the outdoor energy storage power supply device for the new energy vehicle and improving the use effect of the outdoor energy storage power supply device.

[0040] The above merely describes preferred embodiments of the present application, and is not used to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
