Specific embodiment
The embodiment of the present invention is described below in detail, the example of the embodiment is shown in the drawings, wherein from beginning to end
Same or similar label represents same or similar component or has the function of same or like component.Below with reference to attached
The embodiment of figure description is exemplary, it is intended to for explaining the present invention, and is not considered as limiting the invention.
Automatic guided vehicle in correlation technique, charging male connector crimp mode up and down with charging female and coordinate, for example, will charge
Male connector is installed on the bottom surface on chassis, and charging female is fixed on ground, and automatic guided vehicle is needed in the case of charging, and is driven into and is filled
Electric area so that the electrode terminal of charging male connector is docked with the electrode terminal of charging female in vertical direction, in this way, automatic guided vehicle
Most of weight charging female is grafted in by charging male connector, the matching relationship of charging male connector and charging female would become hard to change
Become.However the situation charge efficiency that charging male connector is not aligned with charging female can substantially reduce or even can not realize charging.
Further, since the positive and negative of charging electrode on ground has been fixed, this allows for automatic guided vehicle can only a side
To charging, if the charging that can only advance either falls back charging operation error or other causes due to some
Automatic guided vehicle then very likely burns out battery or even burns out entire nothing there is no charging according to the advance and retreat mode of setting
The electric-control system of people's carrier.The present invention puts forth effort to solve above-mentioned technical problem.
Referring to Fig. 1-Fig. 4 descriptions charging unit for automatic guided vehicle according to embodiments of the present invention, the charging
Device includes the charging male connector 10 and charging female 20 of separable cooperation.
Specifically, charging male connector 10 has the first charging part, and charging female 20 has second with the cooperation of the first charging part
Charging part, one of charging male connector 10 and charging female 20 are installed on the car body of automatic guided vehicle, another is fixed on
Ground.That is, being installed on the situation of car body in charging male connector 10, charging female 20 is fixed on ground, in charging male connector 10
The situation on ground is fixed on, charging female 20 is installed on car body.
In the case of electricity abundance automatic guided vehicle workspace automatic running in the case of not enough power supply nobody remove
Fortune vehicle sails out of workspace, drives into charging zone, is docked by the first charging part with the second charging part and cooperatively form current loop, so as to
Automatic guided vehicle is implemented to charge, is completed after charging, the first charging part is with the second live part from automatic guided vehicle, which sails out of, to be filled
Electric area.Coordinate in the first charging part of situation and the second charging part of charging, the first charging part and the after charging electricity and completing
Two live parts from.
