Description

Technical Field

[0001] The utility model relates to the technical field of new energy vehicles, and in particular to a quick connection structure of a vehicle-used battery-changing generator. Background Art

[0002] New energy vehicles have achieved rapid development in my country with their low emissions, low operating costs and good driving experience. At present, there are two constraints on the promotion of electric vehicles. The first is the vehicle range, and the second is the cost of the vehicle. There are two aspects to the vehicle range problem. First, during daily use in winter, the vehicle range is greatly shortened due to the reduction in battery activity. The thermal stability system of the vehicle battery pack relies on the battery to consume electricity to generate heat. Therefore, even if the battery activity is improved, it has little effect on the battery life of the electric vehicle. Second, the range is insufficient for long-distance travel. The main usage scenarios are short-distance travel needs such as urban commuting or short-distance travel, and the annual usage rate of long-distance travel is low.

[0003] At present, the battery cost of an electric car basically accounts for 35% of the total cost of the vehicle. Increasing the battery capacity will increase the total weight of the vehicle, increase power consumption, and increase costs. The current common solution is to use the range extension method. When the new energy vehicle is equipped with a battery, a fuel engine is installed. When the battery is low, the fuel engine starts and the engine replenishes the battery. Second, the new energy range extension vehicle has high use costs and heavy weight. The existing car swap stations can quickly solve the above problems. However, the swap station has problems such as huge investment and low penetration rate. The range extender for new energy vehicles is equipped with a generator composed of a fuel tank, an engine radiator, a motor radiator, a DC charging gun, etc., which is used to replace the battery replacement battery. A low-cost swap station is built, and the generator is replaced. It can be borrowed and returned in different places across the entire network. It can solve the long-distance anxiety and long charging time problems of new energy vehicles. It can reduce the battery used in new pure electric new energy vehicles by more than half, reduce the weight and cost of new vehicles, and solve the long-distance endurance problem of new energy vehicles. If there is no time to charge, you can go directly to the swap station to replace the generator.

[0004] The patent number CN202310824745.9 provides a plug-in connection structure between the vehicle range extender and the base, which has four problems: 1. The range extender and the vehicle are directly connected with screws. Without the engine bracket shock absorption, the engine vibration will be transmitted into the cab; 2. The current output by the generator is connected to the vehicle through a relatively complex high-voltage socket designed by him; 3. There is no quick lifting interface; 4. The factory-produced range extender needs to be equipped with peripherals such as a fuel tank, engine radiator, radiator kettle, generator radiator, etc. to form a generator.

[0005] We now have extended-range vehicles, which usually carry an engine and generator, making the vehicle heavier and requiring battery power, wasting energy. Pure electric vehicles have long-distance anxiety, are not easy to charge on highways during holidays, and sometimes need to use the vehicle urgently but the waiting time for charging is too long.
