Description

Title of the invention: H1-free charging and power supply system technical field

[0001] The invention relates to the technical field of wireless charging or power supply systems. More specifically, the invention relates to locking an electric battery onto a docking station of a wireless charging or power supply system. State of the art

[0002] In order to power or charge electronic equipment in a public space, for example in a restaurant or waiting area, it is known to integrate a wireless charging or power supply system into the furniture in that space. This type of system allows energy to be transmitted from a wireless charging station to an electronic device placed on the furniture, for example, by inductive coupling between a coil located in the charging station and a coil located in the electronic device. It should be noted, for example, that the Qi standard describes a technology enabling this type of wireless energy transmission.

[0003] To avoid connecting the charging or power supply system to the mains and thus having wires running to the mains with a risk of tripping or an unsightly appearance, it is known to integrate a battery into the system. The battery can then provide the electrical power necessary to charge or power the remote electronic device. However, since the furniture is accessible to the public, it is necessary to provide a solution for locking this battery to the system to prevent its removal, particularly to prevent theft. Nevertheless, the solution must allow for quick and easy unlocking of the battery by authorized personnel, to allow for battery maintenance or replacement with a new battery when it is discharged.

[0004] However, known systems are often large, unsightly and could be torn off using a power take-off.

[0005] The invention therefore falls within this context and seeks to resolve all the aforementioned drawbacks. Thus, the invention aims to provide a wireless charging or power supply system comprising a battery to provide the electrical power necessary for this charging or supply, which can be locked or unlocked simply and quickly while remaining unobtrusive once installed on its support and which is difficult to remove.

[0006] A locked configuration is defined as one in which the locking element and the locking counterpart cooperate to prevent the battery from being removed from the docking station. Conversely, in the unlocked configuration, the locking element and the locking counterpart no longer prevent the battery from being removed from the docking station. It is thus understood that, thanks to the invention, it is necessary to use a specific key capable of emitting a magnetic field in order to unlock the battery from its docking station. Unlocking is therefore complex, or even impossible, without this key, whereas it is simple and quick when this key is available. Presentation of the invention.

[0007] The invention relates to a wireless power supply or charging system comprising a charging station having a battery and a housing in which the battery is arranged, the housing having an upper face and a lower face, and at least one locking element arranged at the upper face and at least one unlocking element arranged at the lower face and; a receiving device comprising a cavity adapted to receive the charging station, the cavity having a bottom and a side wall, said receiving device having at least one additional locking element arranged at the bottom;at least one locking element and at least one complementary locking element are arranged to cooperate together and to adopt a locked configuration when the charging station is installed in the cavity of the receiving device, and to adopt an unlocked configuration under the influence of a unlocking device comprising at least one complementary unlocking element adapted to cooperate with the unlocking element of the underside of said charging station. The system is notable in that the underside has a continuous surface delimited by at least one edge, and in that, when the charging station is installed in the cavity of the receiving device, said edge comes into contact with the side wall of said cavity, defining an obtuse angle between the underside and the side wall.

[0008] The housing can be adapted to contain and protect the battery, the antenna, and also all the printed circuit boards of the power supply system. The upper face of the housing can be substantially flat and the lower face can be slightly convex to make it difficult or even impossible to grip the charging station when it is in the locked position.

[0009] The charging station may advantageously include two locking elements. In another embodiment, the charging station may include three locking elements. In a different embodiment, the charging station may include four locking elements. At least one locking element can be positioned against the top face of the charging station housing, i.e., in contact with said top face. In one embodiment, at least one locking element can be positioned less than 2 mm from the top face of the charging station housing.

[0010] At least one unlocking element can be positioned a few millimeters away, for example at a distance of between 1 mm and 5 mm from the underside of the charging station housing.

[0011] The receiving device may include means for attaching it to a furniture surface. The receiving device may be attached to a furniture surface by means of screws and / or glue. The receiving device may include a cavity, which may be concave. The receiving device may advantageously include two additional locking elements, arranged longitudinally on either side of the battery. In another embodiment, the receiving device may include three additional locking elements. In a different embodiment, the receiving device may include four additional locking elements.

[0012] The locking element and the complementary locking element are positioned so that they can be opposite each other when the charging station is installed in the receiving device.

[0013] A user who wishes to lock the charging station in the receiving device positions it in his hand and by passing the charging station to the level of the receiving device, the locking element and the complementary locking element will automatically attract each other and cooperate together so that the charging station is easily positioned in the cavity of the receiving device.

[0014] The unlocking device may allow the locking element of the charging station and the complementary locking element of the receiving device to cease cooperating so that said battery can be extracted from the cavity of the receiving device.

[0015] The edge can be adapted to serve as a positioning element for the charging station within the receiving device. Thus, when the user seeks to install the charging station in the receiving device, the edge can cooperate with the side wall of the cavity in the receiving device so that the charging station is perfectly positioned within the cavity.

[0016] Advantageously, the cavity of the receiving device comprises a bottom and a side wall, said side wall comprising an internal surface on the side of the cavity and an external surface, said internal surface and said external surface being connected to each other by a slice.

[0017] The slice can be oblique towards the inside of the cavity, that is to say that the surface The internal surface is shorter than the external surface.

[0018] The junction between the slice and the external surface is adapted to cooperate with the edge of the charging station. Thus the lower face of the charging station and the external surface of the cavity of the receiving device form a continuous surface broken by an angle formed by the edge of the charging station and by the junction between the edge and the external surface of the wall of the cavity.

[0019] Advantageously, the charging station housing has an upper face arranged opposite the bottom of the receiving device, a lower face adapted to close the housing and a side face adapted to connect the upper face and the lower face.

[0020] In one embodiment, the upper and lower faces of the housing are clipped together at the side face. In another embodiment, the upper and lower faces are mounted together at the side face and then held together by gluing. In yet another embodiment, the upper and lower faces are mounted together at the side face and then held together by ultrasonic welding.

[0021] The upper and lower faces can be clipped together by means of male and female fastening means. The male and female fastening means can, for example, be lugs mounted on the lower face of the housing, adapted to be inserted into tubes mounted on the upper face of the housing.

[0022] The cavity can be adapted to fully receive the side face of the charging station.

[0023] When the charging station is mounted in the cavity of the receiving device, the upper face may be opposite the bottom so that the upper face and the bottom are in contact. When the charging station is mounted in the cavity of the receiving device, the side face may be opposite the side wall of the cavity so that the side face and the side wall are in contact.

[0024] Advantageously, the side face of the charging station housing comprises a first part opposite the internal surface of the side wall of the receiving device and a second protruding part arranged opposite the edge of said side wall.

[0025] The lateral face can be divided into two parts, a first part and a second part forming an obtuse angle between them.

[0026] When the charging station is inserted into the cavity of the receiving device, the first part may be facing the inner surface of the side wall of the receiving device, so that the first part and the inner surface may be in contact. When the charging station is inserted into the cavity of the receiving device, the second part may be facing the edge of the side wall of the receiving device, so that the second part and the slice can be in contact.

[0027] Advantageously, the side wall of the receiving device is a first inner side wall and in that said receiving device comprises a second outer side wall extending beyond the first inner side wall so as to form a channel between said inner wall and said outer wall.

[0028] The presence of the second side wall and the channel formed between the first and second side walls prevents the insertion of a knife or any other object that could be used to pry open the charging station. Thus, once the charging station is installed in the cavity of the receiving device, it cannot be removed without the use of the unlocking device.

[0029] The presence of the channel between the first and second lateral walls can facilitate the insertion of the charging station into the cavity.

[0030] Advantageously, the charging station includes a projection on the upper face, said projection including a charging module and an antenna, the charging module being arranged to receive electrical power and to transmit it to the antenna, which is arranged to transmit this electrical power to a remote electrical device to charge or power it electrically.

[0031] It is the charging station which, from the electrical power produced by the battery, can transmit said electrical power to the antenna, itself adapted to deliver said electrical power to the electronic device to be recharged.

[0032] The protrusion allows the charging station to be positioned within the cavity of the receiving device. The protrusion may include an antenna support adapted to receive said antenna.

[0033] The charging module can be arranged to receive electrical power and to transmit it to the antenna, which can be arranged to transmit this electrical power to a remote electrical device to charge or power it electrically.

[0034] Advantageously, the base of the receiving device has a perforated housing adapted to receive the protrusion of the charging station.

[0035] The housing may have a profile substantially identical to the profile of the protrusion of the charging station so that said protrusion can be inserted into said housing.

[0036] The housing can be perforated to limit the thickness between the antenna and the element to be charged. Indeed, depending on the charging standard used, a certain distance may be necessary for charging to function.

[0037] Advantageously, the receiving device is mounted on an underside of a furniture tray by at least one fastening means.

[0038] The means of fixing the receiving device to the underside of the furniture top may include glue and / or screws.

[0039] Advantageously, the receiving device includes at least one suitable hole for receiving the additional locking element, said hole being arranged so that the additional locking element is opposite the locking element of the charging station when they cooperate.

[0040] In a preferred embodiment, the receiving device has two holes. In another embodiment, the receiving device has three holes. In a different embodiment, the receiving device has four holes.

[0041] The additional locking element may have a diameter substantially identical to the diameter of the bore so that said additional locking element is perfectly inserted into said bore.

[0042] Advantageously, the locking element and the unlocking element each comprise at least one magnet.

[0043] In a preferred embodiment of the invention, the locking element may comprise three magnets and the unlocking element may comprise a single magnet.

[0044] In another embodiment, the locking element may comprise two magnets and the unlocking element may comprise a plurality of magnets.

[0045] Advantageously, the locking element and the complementary locking element each comprise at least one magnet with an adhesive force between 100 N and 300 N.

[0046] The magnet of the locking element and the magnet of the complementary locking element may have opposite polarities.

[0047] Each magnet of the locking element and the complementary locking element can have an adhesive force of between 24 N and 26 N.

[0048] Advantageously, the unlocking element of the charging station includes at least one magnet whose adhesive force is greater than the adhesive force of the magnet of the locking element.

[0049] The charging station's release mechanism can be adapted to allow the charging station to be removed from the cavity of the receiving device. This is achieved by using a release magnet with a stronger adhesive force than the locking magnet, which allows the charging station to be removed from its position in the receiving device.

[0050] Advantageously, the unlocking element of the charging station includes at least one fastening means having an alternation of polarities.

[0051] The means for attaching the unlocking element may include at least one magnet. In a preferred embodiment, the unlocking element may comprising two magnets. In another embodiment, the unlocking element may comprise three magnets.

[0052] In a preferred embodiment, the magnet of the unlocking element may include a self-centering round toroidal magnet which can make it easy to center the unlocking element but also to use a complementary magnet having the same alternating polarities which are complementary.

[0053] The radially magnetized toroidal magnet allows the unlocking device to be quickly and easily self-centered when a user reaches under the table to unlock the charging station. Using a toroidal magnet can create a kind of key, requiring a complementary key to unlock the charging station. Indeed, if a malicious individual attempts to steal the charging station with a conventional magnet whose adhesive force is greater than that of the locking elements, the conventional magnet will be disoriented by the dual polarization and will not be able to adhere optimally to the charging station, making it impossible to remove the charging station from the cavity.

[0054] In another embodiment, the charging station unlocking element comprises a plurality of magnets, for example, five magnets with a first polarity on their visible face and four magnets with a second polarity on their visible face, the five magnets being arranged alternately with the four magnets. In this same embodiment, the additional unlocking element comprises five magnets with a second polarity on their visible face and four magnets with a first polarity on their visible face, the five magnets being arranged alternately with the four magnets. In this embodiment, it may be possible to arrange the five magnets with the first polarity in a cross pattern and the four other magnets with the second polarity alternately with the other five.It is also possible to arrange the magnets with other specific patterns so that only the complementary unlocking device with the same complementary pattern can unlock the charging station from its cavity.

[0055] Another aspect of the invention relates to a device for unlocking a wireless power supply or charging system, comprising a cavity in which the complementary unlocking element is mounted, said cavity being adapted to cooperate with the charging station so that the complementary unlocking element cooperates with the unlocking element of the charging station.

[0056] The unlocking device may include a closed cavity located on its upper face when said device is in the unlocked position, i.e., in the position in which it is placed to unlock said charging station. The closed cavity includes a complementary unlocking element designed to cooperate with the unlocking element of the charging station. Thus, when the unlocking device is positioned in contact with the charging station, the complementary unlocking element can be attracted to and engage with the unlocking element.

[0057] Advantageously, the additional unlocking element is a magnet.

[0058] The magnet of the complementary unlocking element may have a polarity opposite to that of the unlocking element.

[0059] Advantageously, the magnet of the complementary unlocking element of the unlocking device has a greater adhesive force than the adhesive force of the magnet of the complementary locking element.

[0060] The additional unlocking element of the unlocking element can be adapted to allow the charging station to be removed from the cavity of the receiving device. It is by using a unlocking magnet with a stronger adhesive force than the locking magnet that the charging station can be removed from its position in the receiving device.

[0061] Advantageously, the additional unlocking element comprises at least one magnet whose adhesive force is between 90 N and 110 N.

[0062] The adhesive force of each magnet of the additional unlocking element can in particular be between 95 N and 100 N.

[0063] Advantageously, the additional unlocking element comprises at least one magnet whose adhesive force is greater than the adhesive force of the magnet of the additional locking element.

[0064] In one embodiment, the additional locking element may comprise a single magnet. In another embodiment, the unlocking element may comprise a plurality of magnets stacked one on top of the other. In a different embodiment, the unlocking element may comprise a plurality of magnets positioned side by side.

[0065] Advantageously, the additional unlocking element comprises at least one fastening means having an alternation of polarities.

[0066] In one embodiment, the additional unlocking element may comprise a plurality of magnets positioned next to each other with a portion of the magnets having the apparent face exhibiting a first polarity and another portion of the magnets having the apparent face exhibiting a second polarity, the magnets exhibiting the first polarity being arranged alternately with the magnets exhibiting the second polarity.

[0067] In another embodiment, the additional unlocking element may comprise a self-centering, radially magnetized, round toroidal magnet having at less an alternation of polarities.

[0068] Another aspect of the invention relates to an assembly comprising a wireless power supply or charging system according to any one of claims 1 to 11 and an unlocking device according to any one of claims 12 to 17.

[0069] Another aspect of the invention relates to a recharging unit for a plurality of charging stations of a wireless power or charging system according to any one of claims 1 to 16.

[0070] The charging unit may have five slots, each adapted to receive a charging station. In one embodiment, the charging unit may have ten slots, each adapted to receive a charging station. The charging unit may be adapted to be connected to the mains. The charging unit may have, in each slot, an additional charging connector adapted to cooperate with a charging connector positioned on the underside of said charging station.

[0071] Another aspect of the invention relates to a furniture tray having an underside having a cavity adapted to receive at least a portion of a system according to any one of claims 1 to 11.

[0072] The furniture surface can be a table, a furniture top, a worktop, a desk, a bar top or any flat surface on which an electronic device can be placed to be recharged.

[0073] Advantageously, the thickness of the tray between the bottom of the cavity and an upper face of said tray must be less than 40 mm.

[0074] In an embodiment using Qi wireless charging technology, the thickness between the bottom of the cavity and the top face of the tray may advantageously be less than 20 mm, in particular less than 10 mm, in particular less than 8 mm.

[0075] This described thickness can allow waves to pass through to enable the induction charging of the electronic device.

[0076] Advantageously, the cavity is arranged to receive at least a portion of an external face of the charging station receiving device.

[0077] The cavity is more or less deep so as to adapt to the thickness of the furniture top so that the thickness between the bottom of the cavity and the top face of said top is adapted to that provided for the induction loading standard used.

[0078] The cavity may have a profile and dimensions similar to those of the receiving device.

[0079] Therefore, the depth of the cavity determines the dimensions of the portion of the external face of the receiving device that will be inserted into said cavity.

[0080] Advantageously, the cavity is adapted to receive the housing.

[0081] In this embodiment, the furniture surface can be thin, so it is unnecessary to deeply embed the power supply or wireless charging system to achieve the required distance for wireless charging operation. In this embodiment, only the housing for the receiving device, adapted to receive the protrusion of the charging station, which includes the antenna, may need to be inserted into the cavity. Thus, in this embodiment, the cavity may have a profile and dimensions substantially identical to those of the housing for the receiving device.

[0082] Advantageously, the cavity has two depth levels so that the shape of the cavity is adapted to receive and cooperate with the external face of the receiving device.

[0083] In this embodiment, the furniture surface may be thick, so it is necessary to push the power supply or wireless charging system inward to achieve the required distance for wireless charging operation. In this embodiment, the housing, as well as a portion of the base and side face of the receiving device, may need to be inserted into the cavity. Thus, in this embodiment, the cavity may have a profile and dimensions substantially identical to those of the receiving device. Brief description of the figures.
