Accurate locking and unlocking automobile-mounted storage battery automatic exchange station

Abstract

The invention belongs to the technical field of vehicle maintenance and relates to an accurate locking and unlocking automobile-mounted storage battery automatic exchange station. The station comprises an automobile locating and lifting mechanism used for locating and lifting an electric automobile and a battery locking and unlocking mechanism used for locating and replacing an automobile-mountedstorage battery. Each locking and unlocking component comprises a locking and unlocking motor and a screwdriver driven by the locking and unlocking motor and further comprises a connecting joint fixedto a main shaft of the locking and unlocking motor. Each screwdriver is provided with a handle part. Each connecting joint comprises a containing cavity used for containing the corresponding handle part. The inner section of each containing cavity is larger than the section of the corresponding handle part. Each of the two sides of each handle part is provided with a protruding lug. Each connecting joint is provided with two kidney-shaped holes formed in the axial direction. Each protruding lug is contained in the corresponding kidney-shaped hole, and each screwdriver cannot be separated fromthe corresponding connecting joint. Each containing cavity provides a small-range motion space for the corresponding screwdriver so that each locking and unlocking component can adapt to a target fixing screw, and the problem that all the locking and unlocking components cannot conduct locking and unlocking operation synchronously due to manufacturing errors of an automobile chassis or automobile-mounted storage battery fixing holes is solved.

Description

technical field [0001] The invention relates to the technical field of battery manufacturing, in particular to a vehicle-mounted battery automatic replacement station with accurate unlocking. 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 driver.

AI Technical Summary

Problems solved by technology

However, the shape of different car chassis and batteries may be somewhat inaccurate due to the manufacturing relationship. The rigidly fixed locking and unlocking mechanism cannot guarantee that each position can correspond to the screw, which will make it difficult to achieve high-efficiency locking and unlocking.
