Description

DEVICE FOR FASTENING AND WIRELESS RECHARGING A MOBILE PHONE TO A DOMESTIC CURRENT.

The present invention relates to a device for wireless charging compatible mobile devices when it is placed in a home electrical socket coupled to a magnetic attachment to hold the receiving device in place during charging.

There is already a domestic device for wireless charging of compatible electronic mobile devices such as mobile phones. This is in the form of a flat transmitting base which is connected to the mains by a cable and a mains charger. The phone is simply lying flat on the base to recharge.

One of the technical problems that arises when using such a device is that it must be automatically connected to the electrical network by a cable.

In addition this device also has the disadvantage of the problem of orientation, centering and maintenance of the device in place on the base during charging.

The present invention aims to solve the problems mentioned above, and therefore aims to remedy these drawbacks.

The present invention aims in particular to remove the cable connection between the charging base and the household electrical outlet to improve its implementation, its use, its integration into the environment and its nomad side.

It also aims to provide an automatic centering device when setting up the mobile phone to optimize the load but also to keep the phone on the base in a vertical position to allow more choice of orientation.

With these objectives in view, the invention relates to a device for magnetically fixing and wireless induction charging compatible mobile devices which comprises a transmitter charging coil and magnets located at the periphery of the coil, the coil and the magnets being mounted in a protective case.

According to the invention, the device is characterized in that it comprises, rigidly connected with the protective housing, a plug type male electrical module for its establishment and its connection directly to a domestic electrical outlet.

According to particular complementary or preferential provisions: the coil and the magnets are located in a plane orthogonal to the direction of insertion of the socket. Magnets keep the mobile device in place on the device even when the device is upright. - The magnets are preferably four in number, and distributed at 90 ° around the coil, such a particular arrangement to ensure the automatic centering of the emitter charging coil with the corresponding coil located on the device, equipped with pads Magnets located in a disposition corresponding to that of the magnets in the protective case. the magnets are neodymium magnets. the device comprises a home base covering the coil and the magnets, and arranged to receive in support of the mobile device. Other features and advantages of the invention will appear on reading the detailed description which follows for the understanding of which reference will be made to the accompanying drawings in which: - Figure 1 is a schematic representation of the device according to the invention, - Fig. 2 is a representation of the device shown in Fig. 1, Fig. 3 is an illustration of the device without the slip-resistant home base showing the holding magnets and the wireless charging-transmitting coil (Fig. 3A). and a schematic front view to view the positioning of the magnets around the transmitting coil (FIG. 3B). Figure 4 is a representation of the magnetic case of the mobile phone (Figure 4A), a representation of the case on the charging device (Figure 4B) and a schematic representation of the different possible positions of the mobile phone. holster on the loading device shown in Figure 1 (fig.4C)

With reference to FIG. 2, the device according to the invention comprises the charge-transmitting coil element (1), the voltage transformer module (2), the standard-standard male electrical plug (3) protection (4), a reception base (5), 4 holding magnets (6), the mobile phone case (7) and 4 holding magnets in the case (8).

The device according to the invention is particularly intended for domestic use. It can be used for devices originally equipped with an induction charging system, to which the magnetic studs required, for example pre-arranged on a self-adhesive sheet, or for devices that are not equipped but capable of internally receiving a device, are adapted. such induction charging system as well as the magnetic studs required, or for devices not equipped, via a hull adaptable to the apparatus and electrically connected thereto, this hull then being provided with a such induction charging system and magnetic studs required.
