Description

Battery replacement platform, battery replacement equipment and battery replacement station Technical Field The invention relates to the technical field of electric automobile power conversion, in particular to a power conversion platform, power conversion equipment and a power conversion station. Background The conventional battery pack arrangement mode of the electric vehicle is generally divided into a fixed type and a replaceable type, wherein the fixed type battery pack is generally fixed on the vehicle, and the vehicle is directly used as a charging object during charging. While the replaceable battery pack is typically secured to the vehicle by means of a removable mounting. The battery pack may be removed to individually perform a replacement or charging operation for the battery pack. And after the replaced battery pack is charged, the battery pack is reinstalled on the vehicle. Currently, for large vehicles, a chassis type power conversion mode of a passenger car is mainly adopted as the power conversion mode. In chassis formula battery replacement mode, the battery package can be installed to electric automobile through battery package replacement equipment, in order to be convenient for the installation and the dismantlement of battery package, battery package replacement equipment need carry out preliminary location with electric automobile earlier, treat preliminary location after, battery package replacement equipment last battery platform can carry out relevant removal operation so that take off the battery package of insufficient voltage from electric automobile to install full electric battery package to electric automobile on. The existing battery pack replacing equipment is 2017112442213, is disclosed in shuttle type battery pack replacing equipment and a battery pack replacing station comprising the same, after the battery pack replacing equipment moves to the bottom of an electric automobile and is initially positioned with the electric automobile, a battery pack replacing station above the battery pack replacing equipment can only linearly move along the length direction of the automobile body, and has no adjusting movement function in the width direction of the automobile body, the adjusting movement direction is single, the positioning precision of the battery pack is low, and meanwhile, the size requirement on the battery pack and the requirement on the whole automobile adapting function are high, so that the positioning and the dismounting of chassis and the battery pack with different sizes cannot be met, and the battery pack replacing equipment is not beneficial to being matched with battery packs with more automobile types and more specifications. Disclosure of Invention The invention aims to overcome the defect that a battery pack replacement requirement of different vehicle types and sizes cannot be met due to single adjustment and movement direction when a battery pack is replaced by a battery replacement platform of battery replacement equipment in the prior art. The invention solves the technical problems by the following technical proposal: A trade electric platform for to electric automobile dismouting battery package, trade electric platform includes: A support part; The battery mounting part is arranged on the supporting part and is used for dismounting the battery pack on the electric automobile; A driving part for driving the battery mounting part to move in a first direction and a second direction relative to the supporting part; the first direction is perpendicular to the second direction. In the scheme, the supporting part is used as a supporting structure of the battery replacing platform to provide stable support for the battery mounting part, so that the battery replacing platform can be guaranteed to have enough stability in the process of disassembling and assembling the battery pack, the battery mounting part can be used for taking the battery pack with insufficient power down from the electric automobile and mounting the battery pack with full power on the electric automobile, the driving part can be used for driving the battery mounting part to move along a first direction and a second direction which are perpendicular to each other, and further, when the battery mounting part is positioned with the battery pack on the electric automobile, the position of the battery mounting part can be adjusted in the plane where the first direction and the second direction are located, the defect that the battery replacing platform can only move along a single linear direction in a traditional positioning mode and has a small positioning adjustment range is avoided, the positioning adjustment range and positioning accuracy of the battery replacing platform are improved, and more automobile types and battery packs with more specifications can be adapted. Preferably, the driving part includes a first driving part for driving the battery mounting part to move in the first
