Description

Description of the invention:

Method for charging accumulators in small mobile electronic devices by means of a small rotating element and a small generator, which are integrated into the device or the accumulator of a device.

Introduction and prior art:

The electrical energy can be obtained by mechanical movements movement has been known for many decades and is already used for power generation for several decades in portable small appliances, such. B. in a car quartz watch of a wristwatch. See also the section "Auto Quartz Movement" under Automatic Watch in de.wikipedi.org,
http://de.wikipedia.org/wiki/Automatikuhr

Since wristwatches have to undergo unwanted everyday mechanical movement when worn on the wrist of a human being through their movement in everyday life, these movements are used to drive a tiny rotary element or momentum element, which in turn drives a very small electric generator that charges an accumulator in the device to operate an electronic quartz movement via an accumulator charge. It can thus be charged via this small rotation mechanism on the generator of the accumulator of the device, which also serves as a buffer and Ladeakkumulator in the device to the clock and their electronic quartz movement even with a few days rest, or without carrying and moving, still operate to be able to. This loading mechanism can therefore be made very small. This principle is to be exploited in the method described here to recharge the batteries of mobile electronic devices, such as cell phones, smartphones, laptops, small television and radio devices or other small electronic devices, which have a rechargeable battery.

The disadvantage here is the higher power consumption of these devices, which probably can not be kept permanently on the movement of the device ready for operation and thus require an interim recharge via an external power supply. Another disadvantage is the increased cost of producing such a Mikrolademechanik and the installation in a device. Furthermore, the use only makes sense if the devices are regularly moved by the user. If z. B. such a mechanism in a device, eg. B. would be installed in a laptop, which is operated by the user only as a local desktop device, the increased cost of the device would not be justified. This can be solved in which the charging mechanism is installed directly in an accumulator or accumulator module for such a device, and only users who operate their device portable, would also have to pay the increased cost of a special accumulator, Which then into the device is used. It would therefore be made special accumulators, which include this loading mechanism. In the course of modern manufacturing technology for electronic components and integrated circuits, an ever lower power consumption of the components and circuits is achieved, which more than justifies the use of this technique. If z. As a user of a cell phone, which is operated almost only in the power-saving state or "stand-by" operation or for retrieving and sending text messages, and the whole day by taking enough to move, a temporary recharging via an external power supply would probably not more required. In the power saving state, the phone would have z. B. a power consumption of 1 milliamps and would be 100 hours ready for use. In average use, with z. As intermediate phone calls, the maximum operating time would fall to 40 hours. With the loading mechanism described here, a temporary reloading of the battery of the device would be no longer necessary when merely receiving or sending a few text messages per day and with average use, the operating time would be limited to z. B. rise 60 hours. This would also justify the slightly higher cost of a device or accumulator incorporating the charging technology. Also very useful is the charging technology when a battery is exhausted and the device turns itself off. When carrying around the device after a few hours, the device can be briefly put into operation again.

Description of the method:

Based on 1 and 2 A detailed description will be given by way of example, where the charging technique is incorporated directly into the accumulator module. 1 ] of a mobile phone was integrated. However, the entire technology can also be incorporated or integrated directly into a device during production.

1 shows a plan view of a Handyakkumulator or to a removable Handyakkumulatormodul, z. B. a lithium-polymer battery module with 1600 milliamp hours, with 50 millimeters in height and 40 millimeters in width. 2 shows the side view from the left side and the entire run is shown here with [d1] and [d2], which consequently consists of d1 + d1, and may amount to a total of 4 millimeters, for example. The identifiers [ 1 ] to [ 16 ] and [CU] are in 1 and 2 shared for better clarity. [ 1 ] denotes that Accumulator module housing, [ 2 ] to [ 5 ] the electrical contacts of the accumulator module to contact after being inserted into a mobile phone, [ 6 ] the battery cell or accumulator cells with z. B. 3.7 volts of voltage, [ 7 ] the microgenerator, [ 8th ] to [ 14 ] a translation mechanism consisting of very flat, small intermeshing gears or plastic discs, [ 15 ] the rotating element in the form of a thin round disk, hollow cylinder or hollow drum of light metal or plastic, [ 16 ] a rotational weight of heavy material, eg. Copper metal, [CU] the charging, control and monitoring electronics integrated in the accumulator module and [R] the mutual direction of rotation of the rotary element [ 15 ].

It will be in 2 shown that mechanical components [ 8th ] to [ 16 ] to a very small depth [d1] of z. 1 millimeter and the battery cells [ 6 ] to less than 3 millimeters [d2], where the total depth d1 + d2 of [ 1 ] as described above For example, 4 millimeters. The round microgenerator [ 7 ] can here z. B. have a diameter of 5 millimeters and a height of 35 millimeters and should with as many very fine wire windings, z. B. round copper winding wire with 0.1 millimeters in diameter, to ensure the highest possible electrical voltage to charge the battery cells even at low rotations of its magnetic core 6 ]. Too low a voltage output would reduce the charge of [ 6 ] and in electronics [CU] an additional voltage converter in the form of a small switching power supply would be required to convert a too low generated voltage into a higher voltage.

It becomes practically the rotation element [ 15 ] with the rotational weight [ 16 ] during movement of the accumulator [ 1 ] in the device by the carrier of the device in any direction [R], to the left or to the right, in rotation, where [ 16 ] With [ 15 ] forms a gravity eccentric. about the translation mechanism [ 8th ] to [ 14 ], the rotational movement of [ 15 ] on the microgenerator [ 7 Which then transfers its electrical energy via the electronics [CU] to the battery cells [ 6 ] gives up. For double-sided rotation [R] of [ 6 ] would be for [ 6 ] For a DC generator, a center-winding, center-winding wire winding in [CU] is required, and for an AC generator, a bridge rectifier to remove the positive and negative of [CU]. 6 ] generates voltage to the correct potential to charge of [ 7 ] via [CU]. For example, a very small buffer capacitor of 100 microfarads in [CU] of [ 7 ] are charged to one of the aforementioned two rectifications to a voltage of 5 volts and then via an electronic switch, for. For example, if a field-effect transistor in [CU], which is also controlled by [CU], reaches 5 V when the charging voltage is reached, this buffer capacitor can supply its stored energy to [CU]. 6 ] submit. It can almost always a short-term energy transfer from the buffer capacitor when reaching the charging voltage or a specific charging energy via [CU] to [ 6 ], which recharges it again and again, albeit to a very small extent, via energy surges from the buffer capacitor. A second possibility would also be conceivable, but which would be less favorable due to micromechanical complexity and cost reasons. Because of this, the rotation element [ 15 ] here also in the depth shown wider or as above declared as a hollow drum. It can be controlled by a gear or disk mechanism in [ 15 ] even a spiral spring in [ 15 ] mechanically by the rotation of [ 15 ], and when a certain tensile strength is reached, a separate axis of rotation over that of [ 15 ] with gearwheel or turntable the absorbed mechanical energy of the spiral spring in the form of rotational movements over [ 8th ] to [ 14 ] at [ 7 ] is transferred until the coil spring has been relaxed, and it can directly via a diode that of [ 7 ] generates electrical energy to [ 6 ] be transmitted. It would be advantageous that no additional electronic components would be required in [CU], eg. B. buffer capacitor or voltage monitoring on the buffer capacitor, but the mechanical effort would refute this. The tensioning of the spiral spring for the functionality of this sequence would have to start anew after discharge or relaxation. This would also require a mechanical discharge clamp and the mechanical susceptibility would be much greater than that of the electronic reloading variant or the electronic recharge of [ 6 ] would be preferable over a buffer capacitor in [CU]. Such a spiral spring clamping mechanism does not have to be in [ 15 ] but can also be found in [ 1 ] about [d1] by the rotation element [ 15 ] respectively.

As a symbol of the functionality of the mechanical translation of the rotational movements of [ 15 ] to [ 7 ] was here in the example in 1 and 2 an exemplary gear ratio with the gears or discs [ 8th ] to [ 14 ] between [ 7 ] and [ 15 ], because a meaningful drive of the microgenerator [ 15 ] would only work correctly with a suitable translation or would be useful. Would that of [ 15 ] generated rotational or rotational movement directly over [ 8th ] to [ 7 ], the shooting scenario of [ 15 ] to [ 7 ] may be endangered because of the stiffness of [ 7 ] and [ 15 ] possibly no rotary motion over [ 15 ] would be possible. Therefore, here in the example three mechanical rotation ratios with [ 9 ], [ 10 ], and [ 11 ], [ 12 ] such as [ 13 ], [ 14 ], but which are not mandatory and should serve as an example only. It should only be shown that the gear ratio of [ 15 ] to [ 7 ] Possibly. with direct transmission of the rotational movement of [ 15 ] to [ 8th ] would not suffice due to excessive force transmission, and therefore in this example three or six further gears or turntables were used, [ 9 ] and [ 10 ], [ 11 ] and [ 12 ], [ 13 ] and [ 14 ], inserted. These can be achieved with sufficient ease of [ 7 ] and [ 15 ] and the rotational movement would be of [ 15 ] on a gear [ 8th ] on the rotation axis of [ 7 ] to [ 7 ] transfer. It can be any number of intermediate rotary elements [ 9 ] to [ 14 ] adapting the translation ratio between [ 15 ] and [ 8th ], whereby the translation fit between [ 15 ] and [ 8th ] a correct rotational movement of [ 7 ] for traceability of [ 7 ] and [ 15 ] is guaranteed.

The micro-toothed wheels or micro-disks [ 9 ] and [ 10 ], [ 11 ] and [ 12 ] such as [ 13 ] and [ 14 ] are located on one axis and the smaller disks [ 10 ], [ 12 ] and [ 14 ] represent here a simple gear ratio, Which at low torque of [ 15 ] the microgenerator [ 7 ] can easily drive. A disadvantage of too large a gear ratio is that a multiple of revolutions of [ 15 ] would be required to complete one revolution of [ 7 ] to enable. If the total gear ratio of [ 15 ] to [ 7 ] For example, 20 to 1 (20: 1) would require [ 15 ] 20 turns in one of the two directions of rotation [R], z. To the left to complete the microgenerator [ 7 ] to allow one complete turn. In practice, here the rotation of [ 15 ] about or to [ 14 ], [ 13 ], [ 12 ], [ 11 ], [ 10 ], [ 9 ] and [ 8th ] on [ 7 ] translated or translated. As previously mentioned, the rotational movement of [ 15 ] directly on [ 8th ], if a certain ease of rotation of [ 7 ] and [ 15 ]. Eventually, the axes of rotation of [ 7 ] to [ 15 ] about micro-magnetic bearings or very accurate and stable plastic bearings made of microstructures, such. As carbon nanostructures, be stored. With sufficient ease of movement of [ 7 ] and [ 15 ], the rotational movement of [ 15 ] to [ 8th ] directly, with the gear ratio at [ 7 ] then, for example, would be 1 to 3 (1: 3), and with only one revolution of [ 15 ] would [ 7 ] could complete three revolutions and significantly more electric power could be generated, which would significantly increase efficiency. In this example, no direct information on the diameters of [ 8th ] to [ 15 ] and a calculation of an exact transmission ratio between these, because this also depends on the size of the accumulator module [ 1 ] or the equipment and the materials or size used. It should be shown that with modern production technology nowadays a trouble-free housing of the entire mechanism in an accumulator module or in small mobile devices such as cell phones or smartphones is possible.

The round transmission elements [ 8th ] to [ 14 ] may consist of tiny gears made of metals or hard plastics as well as tiny plastic or plastic or hard rubber discs, which interlock, and Which z. B. have a thickness of 0.2 millimeters. The rotary components [ 9 ] to [ 15 ] are due to tiny axes in the housing [ 1 ] of the accumulator module, see also 2 , The entire construction of the mechanical components [ 7 ] to [ 16 ] can also be modular, which means that they are manufactured in a separate housing and used in a device during manufacture, whereby in case of failure only the module has to be changed. The disadvantage is that if a battery is manufactured with this technology, it must probably be disposed of or disposed of in case of defect, because a repair would not be worthwhile. It would also be conceivable that, for example, in a mobile phone or laptop behind or under the accumulator there is a second reservoir into which a module with the components [ 7 ] to [ 16 ] is used. It would have to change z. B. the back cover of the device are removed, then the accumulator can be removed and then after removal of a defective module a new one can be used. For larger devices, such as laptops, this modular exchange technology for size reasons is no problem, but with sufficiently flat design of such a module, z. B. under 1 millimeter depth, should also succeed in cell phones.

The production is no problem today, which can be proven, for example, on a modern small mechanical movement of a wristwatch. Also automated production techniques, eg. B. by manufacturing robots, this can easily.

The rotation element [ 15 ] may, as already mentioned above, consist of a round hollow drum with spiral spring mechanism inside, or of a complex gear or a disk, which is made of the same materials as [ 8th ] to [ 15 ], and for example, have a depth of 0.8 millimeters. [ 15 ] is like [ 8th ] to [ 14 ] also over a tiny axis in [ 1 ], possibly also via micro-bearings in [ 1 ]. The rotational weight [ 16 ] consists, as already mentioned above, of a heavy metal, e.g. As copper, possibly also made of a heavy plastic, and can as in 1 and 2 to see cuboid in [ 15 ], and for example, have the dimensions 0.4 × 0.4 × 0.8 millimeters. The choice of size and shape, which includes the weight of [ 16 ], can be chosen freely, z. B. also a spherical shape. A higher weight of [ 16 ] would more torque in [ 15 ], but are larger in size, and therefore limit the ability to rotate in the circular motion [R], thereby 1 ] would have to be moved more extensively. Smaller dimensions of [ 16 ] in [ 15 ] would do one smaller range of motion of [ 1 ] require. Also conceivable would be weight anchor shapes of [ 15 ] With [ 16 ] like a mechanical automatic watch. The design of [ 15 ] and [ 16 ] should vary depending on the size of the device or accumulator module as well as the transmission ratio to [ 7 ] and the size of [ 7 ].

There are therefore no limits to the design, but it should be possible with as little scope of movement as possible [ 1 ] or as much electrical energy as possible from [ 7 ] for charging the battery cells [ 6 ] be won. It can be designed in larger devices such as laptops larger overall, with more energy can be obtained, but this is almost compensated by the usually higher power consumption of these devices.

It can transfer the rotational movements of [ 15 ] to [ 8th ] also take place via a very small toothed or V-belt, which is certainly easily achievable on this scale mechanically and in terms of manufacturing technology today.

Furthermore, the entire rotation charging technology can 1 and 2 in a small portable device with the dimensions of z. B. 50 × 40 × 30 millimeters are housed, Which z. B. in a hand or jacket pocket is constantly carried by a user of a mobile phone with around, and Which is used in exhaustion of the battery of the phone as an emergency charger, using a special cable with two plugs and a female connector on the emergency charger and on the phone or on the device, the accumulator of a device can be partially recharged by connecting the emergency charger via the cable of the accumulator of the device to be charged again. By carrying around the emergency charger with the rotary charging technology, an accumulator is charged in this, which When connected to a utility device, eg. B. cell phone, whose accumulator can recharge. It can also be used a battery with higher capacity, z. B. 3500 milliamp hours, but then again depends on the design of the size of the emergency rotary charger. It can be made small devices, but then in turn load a small accumulator and thus can provide less energy to load, or larger devices with a larger accumulator.

All electronics [CU] to control the charge of [ 6 ] can be placed on a small circuit board and / or on an integrated circuit, and loud, for example 1 and 2 at designated position [CU] in the accumulator module [ 1 ] or, in the case of a modular construction of the rotation mechanism on the motherboard, the device itself. The contacts [ 2 ] to [ 5 ] put in 1 and 2 the electronic connection of an accumulator module [ 1 ] after its insertion into a utility device to the electronics of a utility. Here, for example, with 4 contacts where z. B. Contact [ 2 ] the negative operating voltage, contact [ 3 ] a temperature monitoring of the accumulator module [ 1 ], Contact [ 4 ] the monitoring of the state of charge of [ 6 ] and contact [ 5 ] represents the positive operating voltage. It could be a separate extra contact to [ 1 ] can be provided to read about [CU] z. B. to transfer the charging efficiency of the rotary charge to the utility, or the rotary charging technology in [ 1 ] via [CU] on and off and control these.

It should be shown in this method that it is possible with today's high state of the art and the high level of manufacturing micromechanical base to construct a mechanical charging technology for batteries and mobile small devices and implement them practically. Also design and size are very variable and are varied depending on the energy requirements of a utility device and its size versatile.
