Abstract

The invention belongs to the technical field of vehicle maintenance, and relates to a vehicle-mounted storage battery automatic replacing station with vehicle body precise positioning. The automatic replacing station comprises a vehicle positioning and lifting mechanism for positioning and lifting an electric vehicle and a battery locking and unlocking mechanism for positioning and replacing a vehicle-mounted storage battery. The vehicle positioning and lifting mechanism comprises two vehicle body positioning assemblies. Each vehicle body positioning assembly comprises a support arranged in asupporting platform, a positioning motor fixed in the middle of the support, and two positioning blocks arranged on the two sides of the support. Two guide rails for limiting the movement of the positioning blocks are arranged on the support. Each positioning motor drives the two corresponding positioning blocks to move along the corresponding guide rail synchronously. The relative positions of the two positioning blocks of each positioning assembly of a vehicle body are not changed, synchronicity is good, and control precision is high; the number of motors is reduced, and device cost is saved.

Description

technical field [0001] The invention relates to the technical field of battery manufacturing, in particular to an on-vehicle battery automatic replacement station with precise positioning of the vehicle body. Background technique [0002] As an environmentally friendly new energy vehicle, electric vehicles have received widespread attention. Electric vehicles are powered by on-board batteries. In order to save charging dwell time, some electric vehicles use removable on-board batteries. That is to say, when the electric vehicle is about to run out of power, the old battery with insufficient power is removed at the replacement station, and then replaced with a new battery with full charge. The dead battery is charged in the replacement station and then supplied to other electric vehicles. In this way, each electric vehicle only needs to spend the time of replacing the battery to restore power, and does not need to wait for charging, which is naturally convenient for the dri...
