Description

Technical Field

[0001] The utility model relates to a power exchange and transfer system for new energy vehicles, belonging to the technical field of new energy vehicle power exchange. Background Art

[0002] As a new type of transportation vehicle, new energy vehicles use storage batteries as energy storage power sources. Electric energy is provided by the battery to drive the motor to operate, thereby driving the vehicle to travel. They have advantages such as zero emissions and a wide range of energy sources. They are an important means to alleviate the shortage of oil resources and serious urban air pollution, and are an effective carrier to promote the transformation of the transportation development mode and the promotion of energy conservation and emission reduction work.

[0003] However, the backwardness of related battery and charging technologies has become the main factor restricting the development of the new energy vehicle industry. New energy vehicles also have the greatest concerns for consumers due to their short battery life, long charging time, and few charging facilities. Although the government and enterprises are making great efforts to improve the supporting charging infrastructure industry for electric vehicles, it is still difficult to solve the problem of charging and energy replenishment for people, and this situation is particularly prominent during holidays.

[0004] Currently, among new energy vehicles with the largest usage, private cars account for a considerable proportion. It is difficult for people to spare time to deal with the problem of charging and energy replenishment for new energy vehicles. Therefore, the fundamental method to overcome the development bottleneck of new energy vehicles is rapid power exchange. Replacing the battery has become one of the rapid energy replenishment methods for new energy vehicles, and the battery is replaced in a timely manner when the battery decays to the point where it needs to be replaced.

[0005] The battery module of a new energy vehicle is installed on the chassis between the front and rear wheels of the vehicle. Currently, most of them lift the vehicle to exchange power from the bottom of the vehicle body, which requires sufficient operating space at the bottom and a sufficiently deep pit for supporting. The bottom operation for power exchange is inconvenient, so the side power exchange method has emerged. The battery can be taken and placed from the side of the vehicle. Although the bottom operation space is small in this way, in order to meet the requirements of its battery life, the battery of a new energy vehicle is generally relatively heavy. During the battery power exchange process, the battery module needs to be taken out and transferred to the charging position in the battery compartment, and it can be placed in the charging compartment for charging. It can also grab the fully charged battery in the battery compartment, transfer it, and accurately place it into the vehicle. Therefore, a power exchange and transfer system for new energy vehicles is needed to solve the problem of transferring the battery module during the power exchange process of new energy vehicles. Summary of the Invention

[0006] The utility model aims at the deficiencies of the existing technology and provides a power exchange and transfer system for new energy vehicles.

[0007] The technical solution of the present utility model to solve the above technical problems is as follows: A new energy vehicle battery swapping and transporting system includes a battery transporting platform, a rotating mechanism for driving the rotation of the battery transporting platform, a lifting mechanism for driving the up and down movement of the battery transporting platform, and a traveling mechanism for driving the front and back movement of the battery transporting platform. The battery transporting platform includes a platform body and a battery traction device provided on the platform body;

[0008] The battery traction device includes a traction table, a traction electromagnet, and a traction driving mechanism. The traction electromagnet is provided on the traction table. The traction table can move on the platform body under the action of the traction driving mechanism. A ferromagnetic structure is provided on the battery and is matched with the traction electromagnet.

[0009] The beneficial effects of the present utility model are as follows: The rotating mechanism can drive the battery transporting platform to turn. When the battery of a new energy vehicle needs to be swapped, the battery transporting platform moves to a position corresponding to the side battery swapping port of the vehicle under the action of the rotating mechanism, the lifting mechanism, and the traveling mechanism. The traction table moves towards the battery on the platform body under the action of the traction driving mechanism, so that the traction electromagnet can act on the ferromagnetic structure of the vehicle battery. Through the adsorption cooperation between the traction electromagnet and the ferromagnetic structure on the battery, under the action of the traction driving mechanism, the movement of the traction table on the platform body pulls out the battery to be swapped on the vehicle. The rotating mechanism acts, the battery turns, and the battery transporting platform rotates 180 degrees with the battery. The battery transporting platform, under the action of the lifting mechanism and the traveling mechanism, carries the battery to correspond to a storage position on the battery storage bin. The traction table can push the battery into the corresponding storage position to wait for charging under the action of the traction driving mechanism. After the battery to be charged reaches the storage position, the traction electromagnet is energized to demagnetize, and the battery can be separated from the traction electromagnet; then the battery transporting platform can move to the storage position corresponding to the fully charged battery under the action of the lifting mechanism and the traveling mechanism. The traction electromagnet can adsorb and cooperate with the ferromagnetic structure on the fully charged battery to pull out the fully charged battery from the storage position. The battery transporting platform moves to a position corresponding to the side battery swapping port of the vehicle under the action of the rotating mechanism, the lifting mechanism, and the traveling mechanism, and inserts the fully charged battery into the vehicle by moving the traction table. The traction electromagnet is energized to demagnetize, and the battery is separated from the traction electromagnet and remains in the vehicle, completing the battery swapping of the new energy vehicle. The structure of the present utility model is simple and compact. During the side battery swapping process, it not only realizes the alignment of the battery with the side battery swapping port of the vehicle and the storage positions on the battery storage bin, but also realizes the rapid insertion and extraction operations of the battery between the new energy vehicle and the battery storage bin, as well as the automated transportation of the battery between the vehicle and the battery storage bin, automated alignment and battery swapping operations, which are convenient and fast, and improve the battery swapping efficiency of new energy vehicles.
