FR2730852A1 - Wire-free current source for moving sliding closure panel across bay - Google Patents

Abstract

The current source includes two distinct parts, an energy emitter (8) which comprises a primary coil (11) around a laminated soft-iron core (11), and a receiver (9) which comprises the secondary coil (14) around its core (13). A constant current regulator (15) charges the buffer batteries (16) which supplies a current through a cable (17) to equipment on the slider. Typically, the half-transformers are 90 mm cubes, separated by 2-30 mm and the output is 24V at 2 Ampere-hours.

Description

 ENERGY TRANSMITTER FOR FREE BAY.

DESCRIPTIONS
The present invention relates to a device which makes it possible to have an electrical energy source on a free bay pow closure, without having to use a wired link.

 The power source is traditionally transported using electric targets (spring return winders, extensible cables, portable carnals), or else supply ducts with collecting trolley. The main drawbacks of these different systems are twofold. In the first place, their imposing dimensions over the entire length of the bay mismatch this and the implementation is often delicate. Secondly, all these devices endure back and forth movements generated by the displacement of the rack and undergo deterioration over time.

 The device according to the invention overcomes these drawbacks. In fact, the power source is no longer carried by a cable or a trolley, from the fixed part of the bay (sleeping frame or discharge area) to the free bay. The transport of electrical energy is made possible using an electromagnetic, magnetoelectric coupler and therefore, no more physical connection exists between the free bay and the fixed parts.

 The device is made up of two separate parts.

 - The transmitting bortier is located on a gallows its face generating the magnetic fields is turned towards the free bay. This bootmaker is made up of a half-transformer which in this design transforms an electric current into a magnetic field.

 - The receiving boot which can be of identical size is fixed on the free rack at the same height as the sending boot and is opposite this when the bay is closed (and) or open. This last is made up of a half-transformer which recovers the magnetic field generated by the emitter casing pow transform it into electric current. The receiving shoemaker stores energy in accumulators the time it is present in front of the transmitting handler. Energy is available on the bay during its opening, its open maintenance, as well as during its closure and its closed maintenance.

The accompanying drawings illustrate the invention:
- Figure I shows a free bay (here sliding gate) equipped with the device according to the invention.

 - Figure 2 shows in section the energy emitting unit and the energy receiving boot.

 Referring to Figure I, the energy source available in the case (3) on the free bay (1) is conveyed to the lamp (7) by the cable (6). To do this, the receiver boot (3) transforms the magnetic fields generated by the transmitter boot (2) fixed to the ground. The transmitter boot (2) is supplied by the cable (5) connected to the network. The displacement of the free bay according to the arrow (4) does not alter the availability of the energy source, buffer batteries in the case (3) store the energy during the maneuver.

 Referring to Figure 2 the transmitter box (8) consists of a transformer which has the primary winding (11) autow the core (10) made of stacked sheets of soft iron.

The receiver box (9) is made up of the second half of the transformer, having its winding in (14) and its core in (13). The current recovered at the ends of the winding is regulated through the constant cowant chargew (15) which stores the energy in the buffer tanks (16).

The energy thus stored can be returned and conveyed by the cable (17) to the equipment located on the mobile rack (7) in FIG. 1.

 The dimensions of the energy transmitters for free racks depend on the energy requirements available on the rack. As a nonlimiting example to obtain an available voltage of 24 Vdc, 2 Amps / hour on the receiver unit we will have a Y, primary transformatew of 903 mm, as well as the secondary transformer Y2, knowing that the distance separating the two Y, transformers being between 2 and 30 mm, and that those d are opposite during the period of charging of the accumulators.

 The device according to the invention is particularly intended for conveying a power supply on a free rack without a wired connection.
