Centering device for wireless energy transmission through non-conductive, non-magnetic materials

Abstract

Centering device for wireless energy transmission through a non-conductive, non-magnetic medium, in particular for awning fabric, glass or plastic, characterized in that at least three magnets in an upper component (e.g. solar module) and at least three corresponding magnets in a lower component (e.g. lamp) are arranged in such a way that they cause automatic centering of transmitter and receiver upon approach.

Description

[0001] The invention relates to a centering device for wireless energy transmission, in particular for outdoor applications in which transmitters and receivers are positioned on opposite sides of a non-conductive, non-magnetic material (e.g. awning fabric, glass, plastic).

[0002] Conventional wireless power transmission systems require precise alignment between transmitter and receiver. This alignment is difficult to ensure in mobile applications or when attached to flexible materials such as awnings. Previous solutions often use fixed mounts, adhesive connections, or clamping systems that are inflexible or complex to install. Furthermore, magnets, if installed centrally, can interfere with power transmission.

[0003] The aim of the invention is to provide a centering device that automatically aligns the transmitter and receiver precisely without disturbing the central transmission area. At the same time, the system should be securely fixed to an insulating support material (e.g., awning, window glass, plastic surface) without the need for additional mechanical fastening and should be movable along this surface.

[0004] The centering device consists of at least three magnets in the upper module (e.g., solar panel) and at least three corresponding magnets in the lower module (e.g., lamp). These are evenly arranged around the central transmitter or receiver. The magnets are designed to attract each other, mechanically clamp the material in between, and enable precise centering through their defined arrangement.

[0005] The central area remains free of magnets to ensure uninterrupted energy transfer between transmitter and receiver. The system is firmly fixed by the magnetic effect, but can be moved along the carrier material for optimal positioning.

[0006] A square solar panel with three magnets is mounted above an awning. A round light with three oppositely polarized magnets is attached to the underside of the awning. When brought together, the modules clamp onto each other through the awning fabric and automatically align so that the transmitter in the panel and the receiver in the light are precisely aligned. The system is stable, can be installed without tools, and can be freely moved along the awning.

[0007] This centering device also works on glass surfaces, plastic panels or other non-conductive, non-magnetic materials, for example when attached to a conservatory window. Explanation of the drawing on page 6

[0008] The drawing shows a preferred embodiment of the invention: Fig. Figure 1 shows a schematic side view of a system with a solar panel (1) on top of an awning fabric (3) and a lamp (2) on the underside. Magnets (4) are attached to the solar panel (1). Magnets (5) are also attached to the lamp (2). The differently polarized magnets (4, 5) attract each other and clamp the awning fabric (3). Fig.Figure 2 shows a schematic top view. The solar panel (1) and the lamp (2) are each shown from the back. Three magnets (4) with negative magnetic polarity are geometrically attached to the solar panel (1) so that the transmitter (6) of the wireless transmission system is exactly in the center of the three magnets (4). Three magnets (5) are also geometrically attached to the lamp (2). These magnets have positive magnetic polarity. The receiver (7) is in the center of the three magnets (5).

[0009] When the solar panel (1) is placed on the awning fabric (3) together with the lamp (2), the magnets (4, 5) attract each other, centering the transmitter (6) and the receiver (7). The awning fabric (3) is clamped between them, and the system adheres to the awning fabric (3) and can be moved along the fabric.
