At present, with the increase of the quantity of automobiles, the pollution of the traditional automobiles to the atmospheric environment by using petroleum as fuel becomes more serious, and the research on new energy electric automobiles becomes a hot topic in order to reduce the pollution of the petroleum gasoline to the atmospheric environment. However, the new energy vehicle still has some problems in the use process, for example, when the electric quantity of the existing electric vehicle is exhausted, it generally takes tens of minutes for a fast charging station to fill up a vehicle power supply battery, and the charging period must be supported and close to the power supply, which consumes a long time and has extremely low charging efficiency. At present, the battery is replaced, and the cruising ability of the automobile is improved by replacing the battery pack of the electric automobile. The existing heavy truck power exchanging mode in the market is that the power is exchanged by hoisting at the top and exchanging with a lateral robot. No matter the hoisting or the side replacement, the power replacement needs to be carried out in a fixed place, the station building cost is high, and the flexibility is relatively weak. The power conversion station is difficult to spread out in a large range, so that the power conversion can be carried out at the charging station without independently constructing a power conversion room.
Corresponding improvement is also carried out aiming at the problems, for example, Chinese patent application No. CN201811384981.9, the publication date is 29/5/2020, the patent discloses a novel pure electric vehicle battery pack quick replacement mechanism, which comprises a vehicle chassis, a supporting mechanism and a buffer mechanism, a battery storage tank is arranged in the vehicle chassis, the bottom of the battery storage tank is rotatably connected with a turnover plate through a third rotating shaft, batteries are placed on the upper surface of the battery storage tank, and two ends of the battery storage tank, far away from the third rotating shaft, are respectively and fixedly connected with a first clamping seat. The disadvantages of the patent are that: although the problem that the electric automobile is not required to be replaced in a professional repair shop is solved, the structure is complex, the load of the electric automobile is increased, and the maintenance among components is complicated.
As another example, chinese patent application No. CN202011406771.2, published as 26/2/2021, discloses a vehicle-mounted battery pack replacement mechanism for an automated battery base station, including: the system comprises a trench, a bearing table and a jack which are arranged on the ground, and a battery base station connected with the trench, wherein the bearing table is connected with the trench in a sliding manner through a sliding rail, and the bearing table can also realize transverse and longitudinal calibration through an auxiliary calibration mechanism so as to align to a power-deficient battery opening of a battery cavity and bear a power-deficient battery pack; a plurality of recovery battery cavities and power battery cavities are arranged in the battery base station, a clamping device is arranged on the battery base station, and the height of the clamping device is adjusted through a lifting rod; the battery base station is provided with an alignment mechanism; the clamping device clamps the replaced insufficient-power battery pack and the power battery pack in the battery base station. The disadvantages of the patent are that: the bearing table only plays a role in bearing transition, and the whole mechanism occupies a large area and increases the cost.
