Description

Battery replacement device of chassis type battery replacement equipment Technical Field The invention relates to the technical field of power conversion, in particular to a battery replacement device of chassis type power conversion equipment. Background The existing battery pack mounting modes of the electric automobile are generally divided into a fixed type battery pack and a replaceable type battery pack, wherein the fixed type battery pack is generally fixed on the automobile, and the automobile is directly used as a charging object during charging. The replaceable battery pack is generally movably installed, and can be taken down at any time and replaced by a new battery pack. For large vehicles, such as light trucks, the vehicle body and the cargo weight are large, so that the vehicle has high capacity requirement on the battery pack, and the electric energy with large enough capacity is required to support the driving mileage of the light truck to meet the actual requirement. Therefore, in the prior art, the batteries of the light trucks of new energy series are generally placed on two sides of the girder of the car body, and the battery pack is borne by the bracket welded on the girder, so that the fixing structure of the car end is complex, and the battery replacement is inconvenient. Moreover, when the power is replaced, batteries are required to be replaced through two power replacing devices on two sides of the vehicle body, so that the field requirement of the power replacing station is high, a large space is required, and meanwhile, the cost of the power replacing station is greatly increased and the efficiency is low due to the fact that two sets of power replacing devices are required. Therefore, for a battery-changing vehicle such as a light truck, a battery-changing mode which is simpler, easier and easier to popularize is urgently needed. For example, a chassis-type power conversion mode of a passenger car is adopted, and in the chassis-type power conversion mode, before a battery pack is detached or installed, a power conversion device (or a power conversion trolley) is required to be controlled to be moved to a power conversion position below the power conversion vehicle, and then lifting operation of a power conversion platform on the power conversion device and battery pack detachment or installation operation are performed to complete the whole power conversion process. However, when the chassis type battery pack is replaced for a light truck and other battery replacing vehicles, the chassis of the vehicle is lower, and the weight of the battery is larger, so that the battery replacing space at the bottom of the vehicle is smaller, the existing battery replacing equipment is easy to cause lower power replacing efficiency when the old battery pack is taken down or a new battery pack is installed, and potential safety hazards are also easy to cause. In addition, when the battery pack is locked and unlocked by the battery replacement equipment in the existing battery pack replacement process, the battery replacement equipment is easy to move relative to the vehicle, so that the battery replacement efficiency is low. Disclosure of Invention The invention aims to overcome the defect of low power conversion efficiency caused by relative movement between the battery pack and a vehicle when the battery pack is locked and unlocked by the power conversion equipment in the prior art, and provides a battery replacement device of chassis type power conversion equipment. The invention solves the technical problems by the following technical scheme: The battery replacement device comprises a vehicle body positioning part and a battery positioning part which are respectively and movably arranged on a base of the battery replacement device, wherein after the vehicle body positioning part is positioned with the battery replacement device, the battery positioning part drives a battery pack to move so as to detach or mount a battery, the battery replacement device further comprises an unlocking mechanism which is arranged on the vehicle body positioning part in a lifting manner and is used for unlocking the battery pack, and a avoidance mechanism is arranged on the battery positioning part corresponding to the unlocking mechanism. In this scheme, when battery replacement device reached the position of changing electricity, automobile body location portion with after the vehicle location of changing electricity, can prevent that vehicle and battery replacement device from producing relative movement, rethread battery location portion carries out accurate location to the battery package, can be right simultaneously through setting up the release mechanism on automobile body location portion the battery package is unblocked to can improve greatly improve the efficiency of changing electricity. In addition, the battery positioning part is provided with an avoidance mechanism at a position corresponding to
