Description

Intelligent management method and device of charging box

Technical Field

The present invention relates to an intelligent management method and device for a charging box, belonging to the technical field of unmanned charging vehicles.

Background technique

At present, the energy of traditional fuel vehicles mainly relies on oil, and the shortage of oil and the serious environmental pollution caused by the exhaust gas emitted by fuel vehicles have made it increasingly urgent for humans to develop new green transportation tools. As a green transportation tool, electric vehicles not only have significant energy-saving effects, but also greatly improve the comprehensive utilization rate of energy, zero exhaust emissions, and obvious environmental benefits. With the continuous advancement of the manufacturing process of rechargeable batteries, electric vehicles will have the strength to compete with traditional fuel vehicles in the near future. At the same time, a prominent problem has arisen. Electric vehicles often cannot continue to drive because the power stored in the power battery is exhausted during driving because they have not reached the charging station. At present, there are few charging stations and they are built in relatively remote locations. Drivers usually need to drive a long distance to reach the charging station, wasting energy. If the power is exhausted before reaching the charging station, it is generally necessary to ask a tow truck to tow the electric vehicle to the charging station, which is costly and very inconvenient, and the towing process may also cause damage to the electric vehicle. Charging stations are generally built in remote places. Buses go to charging stations specifically for charging, which wastes energy. Charging stations are not yet perfect, which limits the popularity of new energy buses. If a large number of charging stations are built, it will waste land and increase construction costs. To this end, the industry has developed a variety of charging vehicles. For example, the Chinese utility model patent with authorization announcement number CN206254816U discloses a storage and transportation type mobile charging vehicle, and specifically discloses a vehicle body, which is provided with an energy storage unit, which is used to replenish electric energy for the vehicle to be charged; and a rescue unit, the vehicle to be charged can be docked with the vehicle body through the rescue unit, and the vehicle body can transport the vehicle to be charged away from the current area through the rescue unit; in the process of transporting the vehicle to be charged away from the current area, the energy storage unit can replenish electric energy for the vehicle to be charged. However, this solution requires manual driving of a large rescue vehicle to the location of the vehicle to be charged, and only one vehicle can be rescued at a time, and the rescue cost is high.

working principle

When the charging box 3 needs to be charged, the unmanned transport vehicle 1 drives until the male end 204 of the connector is aligned with the external charging mechanism up and down, and then the motor 102 of the lifting mechanism 4 at the lower end of the charging box 3 drives the worm gear reducer 103 to operate, and the worm gear reducer 103 drives the connecting rod 104 to rotate. When the connecting rod 104 rotates, the first thread 105 and the thread on the first threaded rod 106 are spirally transmitted to realize the rise of the first threaded rod 106, and the support rod 107 at the lower end of the first threaded rod 106 moves with the first threaded rod 106, and the support foot 109 at the lower end of the support rod 107 is supported on the ground, slowly lifting the charging box 3, so that a gap appears between the carrier frame 2 and the charging box 3, and then the unmanned transport vehicle 1 drives away from under the charging box 3, and then the motor 102 of the lifting mechanism 4 is reversed, so that the charging box 3 descends, and the male end 204 of the connector is inserted into the external charging mechanism for charging. After charging is completed, the charging box 3 sends a signal to the unmanned transport vehicle 1, and the unmanned transport vehicle 1 drives to the charging box 3. The lifting mechanism 4 lifts the charging box 3, and then the unmanned transport vehicle 1 turns its back to the opening of the protective cover 25 at the lower end of the charging box 3, and aligns the supporting frame 2 with the opening of the protective cover 25. Then the unmanned transport vehicle 1 pours into the lower end of the charging box 3. When the lower end surface of the charging box 3 can be completely placed on the supporting frame 2, the lifting mechanism 4 lowers the charging box 3 and fits it with the supporting frame 2. Then the unmanned transport vehicle 1 carries the charging box 3 to the designated location. After arriving at the designated location, the lifting mechanism 4 at the lower end of the charging box 3 lifts the charging box 3, creating a gap between the charging box 3 and the carrier frame 2. The unmanned transport vehicle 1 then drives out to separate the carrier frame 2 from the charging box 3. The unmanned transport vehicle 1 then returns to transport the next charging box 3. The charging box 3 placed here is equivalent to a small charging station. The vehicle is charged by pulling out the output charging head 6 from the slot 8. After the power in the charging box 3 is exhausted, the unmanned transport vehicle 1 carries another fully charged charging box 3 for replacement or directly takes the charging box 3 away.
