Description

1. General

Mobile machinery and electric vehicles today require a strong and efficient low-loss power supply.

For this purpose, connecting elements or connectors are often connected via flexible cables or cable drum systems.

In the field of electromobility, plugs are used to recharge batteries or energy storage devices, which are conventionally connected to the power supply system via cables.

These systems do not meet the requirements that are placed on a handling, especially in the elevated area, moreover, it is not possible to automate the loading of vehicles. Real protection against vandalism is also not possible at these facilities.

The after VDE DIN EN 6185121 Conductive charging technology used in previous applications can only be considered as a cheap transitional solution because it does not meet today's technical possibilities with regard to automation.

The invention automatic connector allows a safe high-performance and low-loss power supply of objects and vehicles to be supplied in certain limited areas with electrical power. For this purpose, on the substructure (chassis / floor panel) of the vehicles, a construction similar to a socket and in the roadway in the operating state accessible extendable plug available.

The system automatic connector is a connector in which the plug or socket automatically position themselves to make an electrical connector. In this case, the system is able to automatically move to a position for connecting the plug elements in a wide range that can make up several meters.

Since the contact elements are operationally put under tension temporarily, these elements are mechanically by a corresponding contact protection according to VDE 0470 Part 1 DIN EN 60529 , protected against unauthorized contact. It is operationally only under tension setting when the contact elements are moved together.

A sensor-controlled safety system allows only authorized persons d. H. Objects or vehicle designs with the appropriate identifier the production of the electrical connection and thus a current drain. Only if entitled d. H. detected by electronic identification objects are present or retract in the area of the recessed in a roadway contact elements, an operating regime is started after the Verbindungslemente (plug or socket) are driven against each other and put under tension.

The system automatic connector allows the use of connectors with any number of poles. The main application of the automatic connector is expected in the field of electromobility for recharging the batteries.

2nd execution

In the system automatic connector for use in charging stations for electric vehicles is in the ground area or roadway ( 3 ), which is traveled by vehicles, a folding by 180 degrees housing ( 1 ) The housing is powered by a rotary actuator ( 24 ) turned to the working position

This housing contains the power supply to a plug ( 4 ) which can be moved in any direction, and thus with the under a vehicle ( 5 ), for example, on the bottom plate ( 6 ) arranged outlet ( 2 ) can be connected.

The automatic connector has a wide-ranging position detection sensor ( 21 ) and ( 23 ) in relation to the sensor ( 15 ) engage the housing in the control of the vehicle, so that the vehicle comes to a halt in the middle about foldable housing.

However, the protective box is only activated if by signals from the vehicle identification sensor ( 21 ) is detected when the position for establishing the contact connection has been detected in the vehicle. The activation (folding) of the housing takes place, however, only if an identifier was received from the vehicle which allows authorization for current consumption and billing.

The central system control is connected to a higher-level EDP with which the energy supply company controls and accounts for the current consumption by the users or vehicles.

If the vehicle or the moving object has reached the required position, then under the vehicle, the foldable housing ( 1 ) around 180 turned so that the plug ( 4 ) points upward in the direction of the vehicle above it.

Now, the ring-shaped light signal transmitter ( 9 ) turned on a conical light beam ( 10 ) for accurate near-field detection.

Within this light cone is now the connector with its photocell sensors ( 8th ). These photocell sensors transmit corresponding signals to the positioning drive of the plug when they enter the cone-shaped light beam ( 4 ).

By means of a control computer, depending on the sensors ( 8th ) the positioning drive ( 12 ) in x- and y-direction, so that the plug ( 4 ) with its guide rod ( 7 ) exactly in the direction of the socket ( 2 ) is positioned. Because the 4 sensors ( 8th ) on the guide rod each detect an angular range of 90 degrees, is a simple control of the positioning ( 12 ) possible.

If the plug by method the proximity of the socket ( 2 ) is reached, by the distance sensor of the drive ( 6 ) turned on a perforated disc ( 18 ) so the contacts ( 22 ) in the plug through openings ( 14 ) become accessible.

The perforated disc prevents the penetration of dirt into the plug while driving the vehicle.

After opening the perforated disc, the guide rod ( 7 ) in the guide sleeve ( 25 ) are retracted. At a certain small distance of the sensors ( 20 ) to sensor ( 19 ), the voltage for the plug is connected, so that from this moment a current flow to the vehicle is possible.

In addition, the guide rod is replaced by a permanent magnet (( 26 In this case, contact is established between the center contact and the PE of the plug.

On the guide rod is an air connection is blown in the compressed air, so that each time the automatic connector is used also a cleaning and possibly drying of the contact technology.
