[0002] Charging device for an electrical device

[0003] Field of invention

[0004] The invention relates to a charging device for an electrical device, in particular for charging electrical devices, such as tablets or smartphones, especially in classrooms.

[0005] Background of the invention

[0006] Electronic devices such as laptops, tablets, and smartphones are increasingly used in schools for learning purposes. These devices are powered by batteries, which may need to be charged during lessons, or the devices may need to be powered externally during use.

[0007] One solution for powering assistive devices or charging batteries is to provide so-called battery drawers that can be inserted into the underside of a desk. The battery drawer (containing a battery) supplies the energy, which is transferred inductively through the tabletop to a corresponding electrical device positioned on the top of the tabletop. A marking on the tabletop can indicate where the electrical device should be placed. However, this requires that the electrical devices themselves are suitable for inductive charging, or that appropriate charging cases are provided. Different devices require different charging cases, which can result in a variety of different charging cases.Another disadvantage of this solution is that the electrical device is charged through the tabletop, meaning it maintains a certain distance from the battery compartment during charging. As the distance increases, the efficiency of inductive energy transfer decreases, which can lead to very long charging times. This solution is both very expensive and not flexible enough.

[0008] An alternative solution is the use of so-called "power units," such as portable power banks, to which the devices to be charged can be connected. Charging can be done, for example, via appropriate charging cables or charging mats (if the device is to be charged inductively). However, the risk of theft is high with these devices. Furthermore, they are difficult to protect against vandalism.

[0009] Object of the invention

[0010] The object of the present invention is therefore to provide a solution that at least partially avoids the aforementioned disadvantages and is nevertheless easy to handle and safe to use.

[0011] Inventive solution

[0012] This problem is solved by a charging device for an electrical device according to the independent claim. Advantageous embodiments and further developments of the invention are specified in the dependent claims.

The guide element is preferably designed such that incorrect insertion into the charging system is prevented.

[0034] It is advantageous if

[0035] - the connection ports include at least one USB port, in particular USB-A and USB-C, and / or

[0036] - the connection sockets are interchangeable.

[0037] In one embodiment of the invention, at least one charging coil of an inductive charging system can be integrated into the terminal plate, wherein the at least one charging coil is coupled to the power supply unit. Together with the connection sockets, several devices can thus be charged simultaneously, for example, one device via inductive charging and another device via a connection socket.

[0038] The invention also provides a charging cabinet for electrically charging a number of charging devices according to the invention, wherein the charging cabinet comprises a body having a door, wherein at least one connection unit is provided inside the body, to which a charging device according to the invention can be connected and via which the connected charging device can be supplied with electrical energy for charging the charging device.

[0052] Detailed description of the invention

[0053] In the following description, the same reference numerals are used for identical features of the devices according to the invention. Figures 1 to 3 are described together below. Figure 1 shows a charging device 1 according to the invention in two different perspective views, with figures (a) and (c) showing the charging device in a first configuration and figures (b) and (d) showing it in a second configuration. When the charging device is not in use, it is in the first configuration. When the charging device is to be used as intended (i.e., attached to a tabletop), it is moved from the first configuration to the second configuration.

[0054] Fig. 2 shows the charging device 1 according to the invention in a side view (Figure (a)), in a front view (Figure (b)) and in a rear view (Figure (c)), where the charging device is in the first configuration.

[0055] Fig. 3 shows the inventive charging device 1 in a side view (Figure (a)), in a front view (Figure (b)) and in a rear view (Figure (c)), where the charging device is in the second configuration.

[0056] The charging device 1 comprises a power supply unit 10, a charging adapter 20, and a mounting device 30. Using the mounting device 30, the charging device 1 can be attached to a tabletop, such as the tabletop of a school desk, as described in more detail below. Alternatively, the charging device 1 can also be attached to a shelf, for example.

[0057] The power supply unit 10 can include a rechargeable battery or a battery. The power supply unit 10 provides the electrical energy required to charge an electrical device using the charging device 1.

[0058] The charging adapter 20 has a number of connection sockets 21 to which an electrical device can be connected for charging purposes. At least one connection socket 21 is provided. However, several connection sockets 21 can also be provided, and these sockets can be of different types. For example, a USB-A socket and a USB-C socket can be provided. Having multiple connection sockets can be advantageous if several devices can be charged simultaneously. However, other types of sockets for charging electrical devices can also be provided.

[0059] In the embodiment of the invention shown here, the connection sockets 21 are arranged on a front end face S of the charging adapter 20, so that they are easily accessible during the intended use of the charging device 1.

[0060] Optionally, it may be provided if the connection sockets 21 are interchangeable.

[0061] In one embodiment of the invention, connection sockets 21 can also be provided, to which, for example, lamps can be connected, such as for lighting the workplace.

[0062] A socket 23 for a charging system (not shown here) can be provided on the end face of the charging adapter 20 opposite the front end face S of the charging adapter. The power supply unit 10 can be charged via the socket 23. For example, the charging device 1 can be inserted into a charging cabinet, which is described in more detail with reference to Fig. 6, where the socket 23 can be connected to a corresponding connector (plug). Such a charging cabinet can be adapted to accommodate several charging devices according to the invention for the purpose of charging the respective power supply unit. Such a charging cabinet is therefore particularly suitable for use in classrooms, especially if the charging cabinet is lockable.At the end of the lesson, all charging devices can be inserted into the charging cabinet, the cabinet can be locked, and the inserted charging devices can be charged. As an alternative to the socket 23 of the charging adapter 20, contacts 11 for a charging system can also be provided on the rear of the power supply unit 10. The contacts 11 are preferably designed and arranged so that they correspond to corresponding contacts in the charging cabinet.

[0063] To ensure safe and correct insertion into such a charging cabinet, it can be advantageous to provide guide rails 22 or the like on the power supply unit 10 and / or on the charging adapter 20. In the embodiment of the charging device 1 according to the invention shown here, corresponding guide rails 22 are provided on the left and right sides of the charging adapter 20. The guide rails 22 are optional.

[0064] The power supply unit 10 is coupled to the charging adapter 20, with the power supply unit 10 providing the electrical energy for charging the devices at the connection sockets 21. In one embodiment of the invention, the power supply unit 10 and the charging adapter 20 can be detachably coupled to each other. In an alternative embodiment of the invention, the power supply unit 10 can be permanently coupled to the charging adapter 20, so that the power supply unit 10 and the charging adapter 20 essentially form a single unit.

[0065] The charging electronics can be integrated either into the power supply unit 10 or into the charging adapter 20. It is advantageous if the charging electronics include a short-circuit protection unit.

[0066] The charging adapter 20 can have a status indicator that, for example, visualizes the remaining capacity of the power supply unit 10. In the simplest case, the status indicator can include an LED that, for example, lights up when the remaining capacity of the power supply unit 10 falls below a certain value. The mounting device 30 is adapted to attach or position the charging device 1 on a piece of furniture, in particular on the tabletop of a school desk.

[0067] In one embodiment of the invention (not shown here), the fastening device 30 can include an eyelet provided on the charging adapter 20 or on the power supply unit 10, to which a strap or loop can be attached. The charging device 1 can be hung on a hook of the table or school desk using the strap or loop.

[0068] In the embodiment of the invention shown here, the fastening device comprises a clamping device 30. In the embodiment of the invention shown here, the clamping device 30 comprises a clamping plate 30a and at least one guide element 30b arranged on the clamping plate 30a. The clamping plate 30a is arranged above the charging adapter 20, running parallel to the top surface O of the charging adapter 20.

[0069] On the underside of the clamping plate 30a, at least one guide element 30b is arranged, consisting of two rods with a round cross-section. The rods are arranged perpendicular to the clamping plate 30a, with each rod being guided into a corresponding opening or guide in the charging adapter 20 and being movable relative to the charging adapter 20. This means that the rods can be moved in and out of the opening or guide in the charging adapter 20. This allows the distance d between the clamping plate 30a and the top surface O of the charging adapter 20 to be changed or adjusted. When attaching the charging device 1 to a tabletop, the distance d can be adjusted according to the thickness of the tabletop. It is advantageous if the distance d can be adjusted continuously.

[0070] The clamping device 30 can be associated with a locking mechanism that allows the clamping plate 30a to be locked at a predetermined distance O from the top surface of the charging adapter 20. For example, after the tabletop has been positioned between the clamping plate 30a and the top surface O of the charging adapter 20, the clamping plate or the two rods can be locked to ensure the charging device is securely attached to the tabletop. To move the clamping plate 30a or to change the distance d, the locking mechanism must be released.

[0071] The locking mechanism can be designed such that increasing the distance d requires manual release of the lock, while decreasing the distance d is achieved without the lock being ineffective. This means that the locking mechanism prevents an increase in the distance d unless the lock is released, but allows the distance d to be reduced without releasing the lock.

[0072] To release the locking mechanism, a release element, for example in the form of a push button 24, can be provided on the front face S of the charging adapter 20, which acts on the locking device when pressed and thus releases the locking mechanism.

[0073] In an alternative embodiment of the invention, locking can be achieved by means of a spring element associated with the clamping device 30. The spring element can comprise a tension spring arranged at the inner ends of the rods, the spring force of which pulls or moves the clamping plate 30a towards the top O of the charging adapter 20. In this embodiment, the clamping plate 30a can be pulled away from the charging adapter 20 for the purpose of attaching the charging device 1 to the tabletop, and after the tabletop has been inserted between the clamping plate 30a and the top O of the charging adapter 20, the clamping plate 30a can be released. The spring elements then cause the clamping plate 30a to be pressed against the top of the tabletop, thus securely attaching the charging device 1 to the tabletop.

[0074] Alternative clamping devices for attaching the charging device 1 to a tabletop are possible and encompassed by the invention. For example, the following clamping devices are possible:

[0075] - Clamps (screw and / or clamping clamps, parallel clamps)

[0076] - Clamps, for example, like tablecloth clips or clothespins, - clamping hooks, which are, for example, attached to a table leg. By inserting the loading device into the clamping hooks, the loading device is locked onto the table leg.

[0077] In one embodiment of the invention, the charging device 1 may be provided with a tracking system that allows the charging device to be located. This is advantageous, for example, if a charging device is stolen.

[0078] It can also be advantageous if the charging device has a unit that allows the entire charging device to be deactivated remotely.

[0079] Fig. 4 shows a charging device 1 according to the invention, which is arranged on a tabletop. The clamping plate 30a has been raised so that the tabletop T can be inserted between the clamping plate 30a and the top of the charging adapter 20. After the tabletop T has been inserted between the clamping plate 30a and the top of the charging adapter 20, the clamping plate 30a can be locked (as described above) to ensure a secure hold on the tabletop. The push button 24 can be pressed to release the lock.

[0080] Fig. 5 shows a further embodiment of a charging device 1 according to the invention in a perspective view.

[0081] A charging coil 50 of an inductive charging device is integrated into the clamping plate 30a, which rests on the top of the tabletop when the charging device 1 is attached to the tabletop. This makes it possible to charge devices inductively using the charging device.

[0082] The electronics required for this can be arranged in the charging adapter 20. The cables for connecting the charging coil 50 to the electronics can be guided from the electronics to the charging coil 50 via the guide elements or rods 30b. The rods 30b can be designed as hollow rods. The charging device according to the invention is designed so that, on the one hand, it can be attached to a table, in particular a school desk, particularly easily. On the other hand, it is designed so that the charging processes can also be carried out safely and easily.

[0083] Fig. 6 shows a charging cabinet 70 according to the invention, wherein in figure (a) the locking device is shown in a closed or locked state and in figure (b) the locking device is shown in an open or unlocked state.

[0084] The storage cabinet comprises a body 71, which is open on one side. A door (not shown in Fig. 6) can be arranged on the open side, with which the body can be closed. It can be advantageous if the door is lockable.

[0085] Casters can (optionally) be fitted to the underside of the body 71. These casters can be swivel casters. It is advantageous if the casters have a locking mechanism to secure them in place.

[0086] Inside the body 71, rails 72 or a rail system 72 are provided. The rails 71 are horizontally oriented and run between the two side walls of the body.

[0087] The loading devices 1 to be loaded or stored in the loading cabinet can be arranged on the rails 71. It can be advantageous if the rails 71 are designed such that the loading devices 1 can only be arranged on the rails in a specific orientation relative to the rails. This prevents incorrect arrangement of the loading devices on the rails.

[0088] At least one connection unit (not shown in Fig. 6) is arranged or provided on the rails 71. The connection unit is designed to correspond with the contacts 11 of the charging device and / or with the socket 23 of the charging device. The charging devices can be supplied with electrical energy for charging via the connection unit.

[0089] The connection units are coupled to a charging unit (not shown in Fig. 6). The charging unit provides electrical energy for charging the charging device. The charging unit is preferably arranged in a lockable or enclosed area inside the housing. This area 75 can, for example, be located in the lower part of the housing. In the embodiment shown in Fig. 6, area 75 has a flap that can preferably be locked when closed. Figure (a) of Fig. 6 shows the flap in the closed position. Figure (b) of Fig. 6 shows the flap in the open position.

[0090] The charging unit itself has a power cable that is routed through a wall of the body to the outside and can be connected to a power source (e.g. a wall socket).

[0091] Inside the body, locking devices 73 are provided with which the loading devices arranged on the rails 71 can be locked. This means that the locking device prevents the loading devices from being removed from a rail.

[0092] A locking device can be designed as a rail (locking rail), a rod (locking rod), or the like. In the embodiment of the invention shown in Fig. 6, the locking device is designed as a rail, wherein the rail is formed from a sheet metal part. Other materials can also be used for the locking device.

[0093] The locking rail 73 is horizontally arranged within the cabinet between the two side walls. The locking rail 73 is parallel to the rail 71. Furthermore, the locking rail 73 is movable relative to the rail 71, allowing it to be moved from a locked position to an unlocked position (or vice versa). This movement can be achieved, for example, by pivoting it about a pivot axis. Alternatively, the locking rail 73 can also be moved by sliding it from the locked position to the unlocked position (or vice versa).

[0094] In Figure (a) of Fig. 6, the locking rails 73 are each shown in a locked position. Locking prevents the loading devices 1 from being removed from the loading cabinet 70.

[0095] In Figure (b) of Fig. 6, the locking rails 73 are shown in an unlocked position. The charging devices 1 can thus be removed from the charging cabinet 70.

[0096] In the case of several rails 72, each rail is assigned a locking rail 73, and it is advantageous if the locking rails can be moved independently of each other.

[0097] The locking rails 73 can be designed to be lockable. This means that the locking rails can be locked in their locked position so that they cannot be unlocked. In the embodiment of the invention shown in Fig. 6, locks 74 are provided for this purpose, which can be operated from the outside. The locks are arranged on a lateral outer wall of the body. Fig. 6 also shows a lock 74 that is associated with the flap of the lockable area 75.

[0098] Through-holes can be provided in the walls, preferably in the rear wall of the cabinet, to ventilate the interior. This ventilation can be passive, occurring without any additional equipment. Alternatively, active ventilation can be provided, for example, by means of a fan that supplies air to the interior of the cabinet depending on the temperature.

[0099] According to the invention, the charging cabinet is designed to be particularly suitable for use in schools, especially in classrooms. The lockable locking mechanism prevents theft of charging devices. After class, all charging devices used during the lesson can be placed in the charging cabinet.

[0100] Fig. 7 shows a section A of a charging cabinet 70 according to the invention with a rail 72 on which two charging devices 1 are arranged. The locking rail 73 is shown here in the open state or in the open position.

[0101] Three receiving shoes 76 are arranged on the locking rail 73, each receiving shoe being designed to receive a loading device 1. In Fig. 7, the left receiving shoe is not occupied, meaning it can receive a loading device 1. The receiving shoe can have guide elements, for example in the form of guide rails, which correspond to the guide rails 22 of the loading device. A loading device can be inserted into the receiving shoe along these guide elements.

[0102] In the rear area, the receiving shoe has a connection unit 77 to which a charging device according to the invention can be connected and via which the connected charging device can be supplied with electrical energy for charging the charging device.

[0103] The receiving shoe 76 can have a locking device with which a loading device 1 inserted into the receiving shoe can be locked in the receiving shoe. This prevents the loading device from unintentionally or automatically detaching from the receiving shoe.

[0104] The mounting shoe 76 can be made of plastic, while the rail 72 can be made of metal.

[0105] Overall, the invention provides a modular and flexible system that is particularly suitable for schools. The charging devices are designed for easy attachment to a school desk without requiring any special fixtures or fittings on the desk itself. Existing school desks can therefore be used.

[0106] Another advantage is that the charging devices can be operated completely wirelessly during use (i.e., when attached to or positioned on the school desk). This simplifies handling and eliminates the risk of accidents in the classroom caused by cables lying around.
