Description

DC Power Supply at variable tension
[0001]. The present invention is directed to a DC power supply system suitable for feeding different apparatuses requiring a variable tension preferably comprised between 1 V and 12 V and which allows an unlimited functioning of the apparatus in the presence of an external source of power (wall plug, PC or in general USB port).
[0002]. The system of the present invention comprises of: at least one removable unit comprising a rechargeable Li-ion battery, and one control unit. Preferably the system comprises at least two removable units, such that while one unit is working, the second one would be ready to use or in charging-mode.
[0003]. The system of the present invention allows the easy and comfortable functioning of devices working with DC power supply without the problem of finding a socket while enormously increasing the lifespan of the device.
[0004]. In the state of the art, it is well known the use of back-up systems for DC supplied devices, such as smartphones, music players, and others electronical devices. Nevertheless, said backup power supply are specific for just one device and they can't be used for a different one.
[0005]. It is therefore needed to have a power supply system which is able to feed any DC powered device with a variable power.
[0006]. The solution provided in the present invention allows to achieve this aim in a simple and effective way.
[0007]. Figure 1 shows a back view of the complete system with a micro USB port (2) for recharging.
[0008]. Figure 2 shows a lateral view in section of an embodiment of the removable unit (1).
[0009]. Figure 3 shows a lateral view in section of an embodiment of the control unit (8).
[0010]. Figure 4 shows the insertion manner of an embodiment of the removable unit (1) into the control unit (8). Magnets (17) allow the fixing of the two parts in a steady way.
[0011]. Figure 5 represents a perspective view of the positive and negative electric contacts (9, 10) and of the spring contacts (18).
[0012]. Figure 6 shows unit (1) inserted in working position into control unit (8) and the magnets (17) in close position which guaranty that the removable unit is steadily fixed in the control unit.
[0013]. Figure 7 shows a block diagram of removable unit (1) which comprises a micro USB port (2), a Li-ion battery recharger (3) connected with LEDs (4) which indicate the status of the charge, a rechargeable Li battery (5), a positive pole of an external electric contact (6) and the corresponding negative pole (7).
[0014]. Figure 8 shows a block diagram of the control unit (8) comprising the input positive
(9) and negative (10) contact, a restorable fuse (11a), a voltage regulation block (l ib), a power regulator (12), a microcontroller (15), connected to the ON/OFF and regulation buttons (14), to status LEDs and LCD display (16), an output collector (13) connected to the regulator (12), which regulator can be directly connected to the apparatus requiring power supply.
[0015]. The micro USB port (2) allows the Li- ion battery (5) to be recharged by connecting unit (1) to a USB port of a PC o to the AC power grid through a converter.
[0016]. LEDs (4) are common charge indicators which are preferably red during the charge process and green when the charge is completed.
[0017]. The Li- ion battery is a conventional battery which at the moment has a charge from 2000 to 7000 mAh. Nevertheless, higher charges could become available over the years, thus making the battery-life longer.
[0018]. In a preferred embodiment, contacts (6) and (7) on the removable unit (1) are metallic tabs, while contacts (9) and (10) on the control unit, are spring contacts (18) as described in fig. 5. In this way, the contact between mobile unit (1) and control unit (8) is particularly steady, which is important so to be able to wear the device around the arm or on the belt.
[0019]. The power regulation (12) is preferably a circuit using complementary symmetry mosfet transistors (Totem Pole), which transistors run the device to be fed. Using the digital technic PWM (Pulse Width Modulation), it is possible to regulate the output tension starting from a minimum value, e.g. 5 V, to a maximum one, e.g. 12 V. The frequency of PWM is preferably of about 24kHz, having a duty cycle which preferably vary between 10% and 100%.
[0020]. As said above, the control unit also comprises one ON/OFF switch and two control buttons. Said switch and buttons can be physically present on the control unit (8) or can be remote and wirelessly connected to the control unit (8). One preferred wireless connection is through Bluetooth. For example, for the best convenience of the operator, it is possible to foresee a pedal-operated ON/OFF switch. Otherwise, in another preferred embodiment, the whole functioning of the system can be run through a specific App on smartphone or tablet, which communicates wireless with the control unit, preferably via Bluetooth. Besides, the voltage regulation can take place through programs set by the user. If, for example, the power supply is mainly used in combination with 3 devices working at 3.6, 4.8 and 12 V, it is possible to pre-set these values, and the switch from one another value directly occurs by pressing a button. [0021]. Control unit (8) also comprises a microcontroller (15) duly programmed to run all the functions of the device such as the power switch on, output tension control through PWM, management of signal LED and supervision LCD display (16). The microcontroller is directly connected to switches, LED and LCD display. A further Step-Up type voltage stabilizer is preferably used as stabilized power generator for the proper working of microcontroller (15).
[0022]. As already said, the power supply unit according to the invention can be used with a wide range of apparatuses. A particularly interesting use of the power supply unit is the one in combination with a tattoo machine. Indeed, it is worthwhile for a tattoo artist to have the possibility of using his or her machinery not only inside his or her workshop, but also in different places such as expositions, where booths are not always provided with power sockets. The power unit according to the invention allows the use of a tattoo machine for prolonged periods. In fact it is enough to change the mobile unit when the battery charge is lowering and replace it with a full charged one to keep on working while the first one is recharging.
