Description

Technical Field

[0001] The utility model relates to the technical field of charging piles, in particular to a charging pile frame suitable for municipal public places. Background Art

[0002] With the continuous development of the domestic economy in recent years, China has become the world's second largest energy consumer. At this stage, the domestic industry can still mainly rely on conventional energy such as coal, which will inevitably have an impact on the development of various domestic industries. Therefore, the development of new energy has become a general trend. New energy vehicles are a major achievement in the development of new energy. New energy vehicles refer to vehicles that use unconventional automotive fuels as a power source (or use conventional automotive fuels and adopt new vehicle power devices), and integrate advanced technologies in vehicle power control and drive to form vehicles with advanced technical principles, new technologies, and new structures. New energy vehicles use electric motors to replace internal combustion engines, and electric motors provide battery packs with power. The electrical energy supplied is converted into mechanical energy to drive the vehicle. The charging pile can safely provide electrical energy for the battery pack in the car. The same is true for the charging piles used in municipal public places. When the existing charging piles in municipal public places charge the vehicle, first insert the charging gun into the charging port of the vehicle. The internal transformer converts the pressure of the current and transmits the electrical energy to the battery pack in the car through the charging cable and the charging gun. The charging cables of traditional charging piles in municipal public places are mostly exposed outside the charging piles. Long-term exposure to wind and sun will greatly reduce the service life of the charging cables. The charging cables will age quickly, and in severe cases, they will break and leak electricity, posing a safety hazard. To this end, we propose a charging pile framework suitable for municipal public places. Utility Model Content

[0026] The working principle of a charging pile frame suitable for municipal public places provided by the utility model is as follows: when using the charging pile in the municipal public place for charging, first pull out the charging gun 554 from the inside of the socket 6, and the single-chip computer 7 controls the motor 2 58 to operate. The output shaft of the motor 2 58 drives the bidirectional screw rod 51 to rotate forward. With the rotation of the bidirectional screw rod 51, the slider 52 and the connecting frame 53 move inward synchronously, and the mounting block 54 also moves upward synchronously. With the movement of the slider 52 and the mounting block 54, the guide wheel 551 also moves inward synchronously, driving the charging line 553 to move, and the limiting wheel 56 prevents the charging line 553 from falling off. At this time, with the movement of the slider 52 and the mounting block 54, the guide wheel 551 also moves inward synchronously, driving the charging line 553 to move, and the limiting wheel 56 prevents the charging line 553 from falling off. As the guide wheel 551 moves, the charging line 553 slowly becomes loose from its original tight state, and the single chip computer 7 controls the motor 1 573 to operate. The output shaft of the motor 1 573 drives the front clamping wheel 572 to reverse. Since the gears 574 are all arranged on the right side of the clamping wheel 572, the two gears 574 are meshed and connected. Therefore, as the front clamping wheel 572 rotates, the rear clamping wheel 572 also rotates accordingly. The two clamping wheels 572 rotate outward synchronously, clamping the charging line 553 so that the charging line 553 is slowly released outward. At this time, the charging line 553 is released, and the charging gun 554 can be used for charging. The current passes through the transformer After the transformer 4 transforms the voltage, the single chip computer 7 controls the transformer 4 to send the current into the battery pack through the charging line 553 and the charging gun 554. After the charging work is completed, the single chip computer 7 controls the motor 1 573 to operate, and the output shaft of the motor 1 573 drives the clamping wheel 572 on the front side to rotate forward. The two clamping wheels 572 rotate inward synchronously, clamping the charging line 553 and slowly retracting the charging line 553. The charging line 553 inside the installation cabinet 2 becomes loose again. At the same time, the single chip computer 7 controls the motor 2 58 to operate, and the output shaft of the motor 2 58 drives the bidirectional screw rod 51 to reverse. As the bidirectional screw rod 51 rotates, the slider 52 and the mounting block 54 rotate outward synchronously. The guide wheel 551 also moves outward synchronously, so that the slack charging line 553 is tightened again until the slider 52 and the connecting frame 53 return to their original positions. At this time, the charging line 553 is tightly wound around the outer surface of the guide wheel 551, and then the charging gun 554 is inserted back into the socket 6 to complete the line reeling work. The charging pile suitable for municipal public places is provided with an automatic line reeling and releasing mechanism, which can quickly and automatically reel in and release the charging line of the charging pile suitable for municipal public places, avoiding the charging line of the charging pile in the municipal public place being exposed to the outside for a long time, increasing the service life of the charging line of the charging pile in the municipal public place, and reducing the occurrence of safety hazards.

[0027] It is worth noting that the single chip microcomputer 7 disclosed in the above embodiment is an S7-200 single chip microcomputer, the motor 1 573 is an SST42D2120 motor, the motor 2 58 is a QCAVS-QCAVP motor, and the single chip microcomputer 7 controls the operation of the motor 1 573 and the motor 2 58 using methods commonly used in the prior art.
