Floating butt-joint device, battery exchange robot, locking method, unlocking method and locking and unlocking method

Abstract

The invention belongs to the battery charging and battery exchange field and relates to a floating butt-joint device, a battery exchange robot, a locking method, an unlocking method and a locking andunlocking method. The invention aims to solve the problems of low battery exchange accuracy and poor stability of an existing battery exchange robot. The floating butt-joint device of the present invention includes a base and a floating portion; the floating portion is configured to float relative to the base; and the floating portion is provided with at least one first positioning mechanism and at least one second positioning mechanism, wherein the first positioning mechanism is so arranged that the first positioning mechanism can be in butt joint with the vehicle body of a vehicle to be subjected to battery exchange can be completed through the floating of the floating portion, and the second positioning mechanism is so arranged that the second positioning mechanism can be in butt jointwith the power battery the vehicle to be subjected to battery exchange through the floating of the floating portion. According to the floating butt-joint device, the battery exchange robot, the locking method, the unlocking method and the locking and unlocking method of the invention, the accurate positioning of the floating butt-joint device and the vehicle to be subjected to battery exchange canbe completed when a battery lack of power is unloaded and a fully charged battery is installed, and the positioning accuracy and battery exchange stability of a battery exchange robot can be improved.

Description

technical field [0001] The invention relates to the field of battery charging and replacement, in particular to a floating docking device, a battery replacement robot, and a locking, unlocking and unlocking method. Background technique [0002] With the popularity of new energy vehicles, how to effectively provide fast and effective energy supply for vehicles with insufficient energy has become a matter of great concern to car owners and major manufacturers. Taking electric vehicles as an example, the current mainstream power supply schemes include charging schemes and battery replacement schemes. Compared with the charging scheme, the battery replacement scheme is one of the main development directions of power supply because it can complete the replacement of the power battery in a very short time and has no obvious impact on the service life of the power battery. The battery replacement plan is generally completed in the charging and swapping station. The charging and sw...
