Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples.
As shown in fig. 1, the charging station according to the invention is essentially formed from mechanical electrodes and electrical functional components in terms of the functional principle.
The mechanical electrode is composed of a charging electrode positive electrode, a charging electrode negative electrode and a charging electrode charging success signal.
The electric functional assembly consists of a battery charger, a direct current contactor and an inductance coil.
The input voltage of the charger in the electrical assembly is AC220V, the output is the charging voltage of the battery, the input voltage of the charging station of the invention is the input voltage of the charger, if the charging station is in the state of electrifying and not working, namely the state of being not butted with equipment or a system, the output charging electrode is not electrified; if the charging station is in an electrified working state, namely, the charging station is electrified and is successfully butted with equipment or a system, the output charging electrode has charging voltage output.
The specific implementation is that the positive electrode of the charger is connected with one end of a normally open contact of the direct current contactor, and the other end of the normally open contact of the direct current contactor is connected with the positive electrode of the charging electrode; one end of the direct current contactor coil is connected with the positive electrode of the charger, and the other end of the direct current contactor coil is connected with a charging electrode charging success signal; the negative electrode of the charger is connected with the negative electrode of the charging electrode.
As shown in fig. 2, the device or system body is also composed of three electrodes, namely, a charging positive electrode, a charging negative electrode and a charging docking signal. The charging butt joint signal of the body is in short circuit with the charging cathode through a wire.
When the equipment or the system is not connected with the charging station, because the normally open contact of the direct current contactor is connected in series before the output of the positive pole of the charging station and the positive pole of the charger, the coil of the direct current contactor is not electrified, and the normally open contact is in a disconnected state, so that the function that the charging point electrode of the charging station is still uncharged even if the input AC220V is introduced is realized; when the equipment or the system is connected with the charging station, as the charging electrode charging success signal of the charging station is grounded through the body end of the equipment or the system, the coil of the direct current contactor is electrified, and the normally open contact of the direct current contactor is closed, the charging electrode has the charging voltage output and can normally charge the equipment or the system.
An inductance coil is connected between the charger and the charging electrode in series to play a role in eliminating contact electric arcs.
In addition, the height of each electrode of the charging station is consistent with the height of the corresponding electrode of the equipment or the system body end, so that the implementation of normal charging can be guaranteed.
The charging station is shown in its entirety in fig. 3.

The electrical functional component consists of a battery charger 1, a direct current contactor and an inductance coil 6, and the direct current contactor consists of a direct current contactor coil 5 and a direct current contactor normally open contact 4.
The positive pole 2 of the charger is connected with the positive pole 7 of the charging electrode through the normally open contact 4 of the direct current contactor, so that only when the coil 5 of the direct current contactor is electrified, the normally open contact 4 of the direct current contactor is closed, and the positive pole 7 of the charging electrode is electrified. One end of a direct current contactor coil 5 is connected with a charger anode 2, the other end of the direct current contactor coil 5 is connected with a charging electrode charging success signal 9, only when the charging electrode charging success signal 9 is equal in potential with a charger cathode 3, the direct current contactor coil 5 can be electrified, a direct current contactor normally open contact 4 can be closed, and therefore voltage output can be realized only at a charging electrode anode 7; the charger negative electrode 3 is connected to the charging electrode negative electrode 8.
The condition of the direct current contactor coil 5 being powered is that when the charging station 10 is docked with the device or system body 11, the charging electrode charging success signal 9 of the charging station 10 is in contact with the charging docking signal 14 of the device or system body 11, and the charging electrode negative electrode 8 is in contact with the charging negative electrode 13, because the charging docking signal 14 of the device or system body 11 is in short circuit with the charging negative electrode 13 through the short circuit lead 15, at this time, the charging docking signal 14, the charging negative electrode 13, the charging electrode negative electrode 8, the charging electrode charging success signal 9 and the charger negative electrode 3 are equal in potential, at this time, the direct current contactor normally open contact 4 is closed, the charging electrode positive electrode 7 of the charging station 10 has voltage output, and the charging station 10 can charge the battery 16 in the device or system body 11.
In order to eliminate an arc generated when the electrode of the charging station 10 contacts the electrode of the device or system 11, an inductance coil 6 is connected in series between the normally open contact 4 of the direct contactor and the positive electrode 7 of the charging electrode, and between the negative electrode 3 of the charger and the negative electrode 8 of the charging electrode, respectively.
The present invention also needs to be designed to note that the height of the positive electrode 7 of the charging station 10 is consistent with the positive electrode 12 of the device or system 11, the height of the negative electrode 8 of the charging station 10 is consistent with the negative electrode 13 of the device or system 11, and the height of the charging electrode charging success signal 9 of the charging station 10 is consistent with the charging docking signal 14 of the device or system 11, so as to ensure the successful docking and charging of the charging station 10 and the device or system 11.
