Description

Technical Field

[0001] The utility model relates to a battery module bearing platform for new energy vehicle power swapping, belonging to the technical field of new energy vehicle power swapping. Background Art

[0002] As a new type of transportation vehicle, a new energy vehicle uses a storage battery as an energy storage power source. It provides electrical energy to an electric motor through the battery to drive the electric motor to operate, thereby driving the vehicle to travel. It has advantages such as zero emissions and a wide range of energy sources. It is an important means to alleviate the shortage of petroleum resources and the serious urban air pollution, and is an effective carrier for promoting the transformation of the transportation development mode and promoting 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 at present, 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 swapping. Replacing the battery has become one of the rapid energy replenishment methods for new energy vehicles, and the battery is replaced in time 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 swap power from the bottom of the vehicle body. Sufficient operating space needs to be set at the bottom, and a deep enough pit needs to be equipped. The bottom power swapping operation is inconvenient, so the side power swapping method has emerged. The battery module can be taken out and put in from the side of the vehicle. Although the bottom operating space is smaller in this way, in order to meet the requirements of its battery life, the weight of the battery module of a new energy vehicle is generally relatively large. If the battery module is pulled out by manpower and then the fully charged battery module is replaced, the manual assistance for the entry and exit of the battery module not only has low power swapping efficiency, but also has a large labor intensity for workers, and there will also be potential safety hazards, and there will also be problems of damaging the vehicle or the battery module during insertion or extraction due to human factors. Summary of the Invention

[0006] Aiming at the deficiencies of the existing technology, the utility model provides a battery module bearing platform for new energy vehicle power swapping.

[0007] The technical solution of the present utility model to solve the above technical problems is as follows: A battery module bearing platform for new energy vehicle battery swapping, including a bearing workbench for supporting the battery module and a traction device arranged on the bearing workbench for pulling the battery module;

[0008] The traction device includes a traction table, a traction electromagnet and a traction drive mechanism. The traction electromagnet is arranged on the traction table. The traction table can move on the bearing workbench under the action of the traction drive mechanism. A ferromagnetic structure matching with the traction electromagnet is arranged on the battery module.

[0009] The beneficial effects of the present utility model are as follows: When the new energy vehicle is swapping batteries, under the action of the traction drive mechanism, the traction table can move on the bearing workbench towards the side battery swapping port of the new energy vehicle, so that the traction electromagnet moves to a position where it can act on the ferromagnetic structure of the vehicle's battery module. Through the adsorption cooperation between the traction electromagnet and the ferromagnetic structure, and the traction table moves away from the vehicle under the action of the traction drive mechanism, the to-be-charged battery module on the vehicle can be pulled out. After the to-be-charged battery is completely taken out, the to-be-charged battery on the bearing workbench can be transported to the battery compartment for charging by a manipulator or other transfer structures. When the battery module needs to be separated from the traction electromagnet, the traction electromagnet is energized to demagnetize, which will not interfere with the separation of the battery module; after taking away the to-be-charged battery module, the fully charged battery module can be transferred to the bearing workbench by a manipulator or other transfer structures for waiting to be inserted. For the fully charged battery module located on the bearing workbench, in order to ensure the stable movement of the battery module, the traction electromagnet can adsorb and cooperate with the ferromagnetic structure on the fully charged battery. The traction table moves towards the side battery swapping port of the vehicle under the action of the traction drive mechanism, and the fully charged battery module can be inserted into the new energy vehicle. After the fully charged battery module is in place, the traction electromagnet is energized to demagnetize, and the battery module is separated from the traction electromagnet and remains in the vehicle, completing the extraction and insertion of the battery module swapping of the new energy vehicle. The structure of the present utility model is simple and compact, the operation is fast and convenient, it can realize the automatic extraction of the to-be-charged battery module and the automatic insertion of the fully charged battery module, improve the battery swapping efficiency of the battery module of the new energy vehicle, and reduce the labor intensity of workers.

When the charged battery module on the traction platform needs to be inserted into the vehicle, the traction drive mechanism acts, the traction platform moves towards the vehicle, driving the charged battery module to be inserted into the side battery swapping port of the vehicle to complete the battery swapping of the new energy vehicle. Whether the battery module to be charged is pulled out from the side battery swapping port of the vehicle or the charged battery module is inserted into the vehicle, the movement of the battery module on the carrying workbench needs to be realized through the traction drive mechanism. Specifically, the traction motor acts, the traction gear rotates, and the meshing transmission between the traction gear and the traction rack realizes the movement of the traction platform on the carrying workbench, realizing the movement of the battery module on the carrying workbench, so as to realize the entry and exit of the battery module in the vehicle.

[0019] Furthermore, the roller assembly includes a roller frame and a plurality of rollers rotatably arranged on the roller frame, and the roller frame is arranged on the carrying workbench.

[0020] The beneficial effect of adopting the above further scheme is that the rollers can reduce the resistance during the movement of the traction platform, reduce the wear between the traction platform and the carrying workbench, and reduce the energy consumption of the traction drive mechanism.

[0021] Furthermore, a guiding mechanism for limiting the movement of the traction platform is further arranged between the traction platform and the carrying workbench.

[0043] The ferromagnetic structure 131 can be a structure such as an iron plate or a steel plate provided on the battery module 13.

[0044] A roller assembly 7 for supporting the battery module 13 is provided on the bearing workbench 6. The battery module 13 can move on the bearing workbench 6 through the roller assembly 7. The rolling friction is small, reducing the wear on the battery mold and the bearing workbench 6, and making the movement of the battery module 13 on the bearing workbench 6 smoother and more efficient.

[0046] A plurality of balls 8 or the roller assemblies 7 are provided on the inner side surface of the side baffle 62. Adding the balls 8 or the rollers 72 to the side baffle 62 can reduce the friction between the side baffle and the side surface of the battery module 13.

[0047] The traction drive mechanism includes a rack 5, a gear 4 meshing with the rack 5, and a drive motor 3 for driving the rotation of the gear 4. The drive motor 3 is arranged on the traction table 1, the gear 4 is arranged on the output shaft of the drive motor 3, and the rack 5 is arranged on the bearing workbench 6. When it is necessary to take the battery module 13 to be charged away from the new energy vehicle, the traction table 1 moves towards the battery module 13, and the traction electromagnet 2 moves to be adsorbed and matched with the ferromagnetic structure 131 on the battery module 13. Then, the traction drive mechanism acts to drive the traction table 1 to move away from the vehicle, and the battery module 13 can be pulled out. When it is necessary to insert the fully charged battery module 13 on the traction table 1 into the vehicle, the traction drive mechanism acts, and the traction table 1 moves towards the vehicle, driving the fully charged battery module 13 to be inserted into the side battery swapping port of the vehicle to complete the battery swapping of the new energy vehicle. Whether pulling out the battery module 13 to be charged from the side battery swapping port of the vehicle or inserting the fully charged battery module 13 into the vehicle, the movement of the battery module 13 on the bearing workbench 6 needs to be realized through the traction drive mechanism. Specifically, the traction motor acts, the traction gear 4 rotates, and the meshing transmission between the traction gear 4 and the traction rack 5 realizes the movement of the traction table 1 on the bearing workbench 6, realizes the movement of the battery module 13 on the bearing workbench 6, and thus realizes the entry and exit of the battery module 13 from the vehicle.

[0049] A guiding mechanism for limiting the movement of the traction table 1 is further provided between the traction table 1 and the bearing workbench 6. The guiding mechanism can limit and guide the movement of the traction table 1 on the bearing workbench 6.

[0050] The guiding mechanism includes a slide rail 9 and a slider 10 adapted to the slide rail 9.

When the towing electromagnet 2 on the towing platform 1 moves to a ferromagnetic structure 131 of the vehicle's battery module 13 where it can act, the towing electromagnet 2 adsorbs and cooperates with the ferromagnetic structure 131 of the battery module 13. The drive motor 3 rotates in the reverse direction, and the towing platform 1 carries the battery module 13 and moves away from the vehicle, enabling the extraction of the battery module 13 to be charged on the vehicle, thus completing the extraction of the battery module 13 to be charged. Subsequently, the battery to be charged on the carrying workbench 6 can be transported to the battery compartment for charging through a manipulator or other transfer methods. When the battery module 13 needs to be separated from the towing electromagnet 2, the towing electromagnet 2 is energized to demagnetize, which will not interfere with the transfer of the battery module 13; when the fully charged battery module 13 is placed on the carrying workbench 6, in order to ensure the stable movement of the fully charged battery module 13, the towing electromagnet 2 can adsorb and cooperate with the ferromagnetic structure 131 on the fully charged battery. The towing platform 1 moves in the direction of the side charging port of the vehicle under the action of the towing drive mechanism, and the fully charged battery module 13 can be inserted into the new energy vehicle. After the fully charged battery module 13 is fully in place in the vehicle, the towing electromagnet 2 is energized to demagnetize, and the battery module 13 is separated from the towing electromagnet 2 and remains in the vehicle, completing the insertion of the battery module 13 of the new energy vehicle.
