Description

BATTERY CHARGER Field of the invention The invention relates to an auxiliary battery charger, and in particular, to a manual battery charger for use with a portable device, for example a mobile telephone. The auxiliary battery charger may either exist as a stand alone device, or form an integral part of the portable device being charged.
Background A major limitation with a mobile phone is the life of the battery. Although many improvements have been made to extend the period for which a phone can be used, there still exists the possibility of the battery being discharged when the user wishes to make a-call.
This has obvious disadvantages, particularly if the user wishes-to make an urgent telephone call.
Summary of the invention According to the first aspect of the present invention there is provided an auxiliary battery charger for a battery operated apparatus, the charging device comprising an operating handle which, in use, is moveable between first and second positions, a first generator, which is driven by the operating handle when it moves from the first position to the second position, and a second generator, which is driven by the operating handle when it moves from the second position to the first position.
According to another aspect of the invention, there is provided a battery powered device having an auxiliary charging device according to the first aspect of the invention.
According to yet another aspect of the invention, there is provided an auxiliary charging device for a battery operated apparatus, the charging device comprising an elongate operating handle for driving at least one generator and means for constraining the operating handle to move in a linear direction along the length thereof.
Brief description of the drawings For a better understanding of the present invention, and to show more clearly how it may be carried into effect, reference will now be made, by way of example, to the accompanying drawings, in which: Figure 1 shows an auxiliary charger according to a first aspect of the invention; Figure 2 shows a three dimensional view of the auxiliary charger according to Figure 1; Figure 3 illustrates how the auxiliary charger of Figures 1 and 2 may be housed in a casing; Figure 4 shows an auxiliary charger according to a second aspect of the invention; Figure 5 shows the embodiment of Figure 4 from a plan elevation; Figure 6 shows an auxiliary charger according to a third aspect of the invention; Figure 7 shows a plan view of the charger of Figure 6; Figure 8 shows the electrical connections; Figure 9 shows a further aspect of the invention in which the auxiliary charger of Figure 1 forms an integral part of a mobile phone; Figure 10 shows a further aspect of the invention in which the auxiliary charger of Figure 4 forms an integral part of a mobile phone.
Detailed description of a preferred embodiment of the present invention Figure 1 shows an auxiliary charger according to a first aspect of the present invention. The auxiliary charger comprises an operating handle 1 which moves between a first, open position 4, and a second, closed position 6. A spring 2 is provided for automatically returning the operating handle from the closed position to the open position. The operating handle 1 has a rack portion 3, which moves between first and second cogged wheels 5 and 7. Each cogged wheel 5 and 7 is connected via a ratchet mechanism to the shaft of a respective generator 9,11. The generators, 9 and 11 are electrically connected (as shown in Figure 8) to a connector 15, which is suitably shaped so as to match a corresponding input connector of the mobile phone to be charged.
Figure 2 shows a three dimensional view of the auxiliary charger of Figure 1. The rack portion 3 of the operating handle 1 is arranged between the cogged wheels 5 and 7, so that they are rotated as the operating handle 1 is moved between the open and closed positions 4 and 6. Cogged wheel 7 is connected to the shaft of generator 11 by a ratchet mechanism such that, in use, when the operating handle 1 is moved from the open position 4 to the closed position 6, cogged wheel 7 drives the generator 11 in a clockwise direction.
When driven in this direction, generator 11 supplies power to charging circuit (shown in Figure 8).
However, when the operating handle moves in the opposite direction, that is from the closed position 6 to the open position 4, the ratchet mechanism makes the cogged wheel 7 free-wheel about the shaft, so that it does not drive the generator in an anticlockwise direction.
Cogged wheel 5, on the other hand, is connected to the shaft of its generator 9 by an opposite ratchet mechanism. When the operating handle 1 is moved from the open position 4 to the closed position 6, the ratchet mechanism makes the cogged wheel 5 free-wheel about the shaft of generator 9, so that the generator 9 in not driven in an anticlockwise direction. However, when the operating handle moves in the opposite direction, that is from the closed position 6 to the open position 4, the cogged wheel 5 drives the generator 9-in a clockwise direction, thereby supplying power to the charging circuit.
In this manner, power is supplied to the charging circuit during movement of the operating handle 1 in both directions. That is, generator 11 supplies power when the operating handle is being closed, and generator 9 supplies power when the operating handle 1 is returning to the open position.
Figure 3 illustrates how the invention may be incorporated-into a casing 19. The operating handle has a thumb pad 21, and the casing 19 has a flange 23. The auxiliary-charger according to this aspect of the invention is operated in-a similar way to a syringe.
That is, two fingers are placed under the flange 23, and the thumb is pressed against the operating handle 1 in a pumping action. This enables it to be small and lightweight, and shaped so that it may be carried easily by the user.
Figure 4 shows an auxiliary charger according to a second aspect of the invention. As before, first and second generators 9 and 11 are provided for supplying power to the battery being charged. Each generator 9, 11 is driven by a rack element, 29 and 31 respectively.
The rack elements 29 and 31 and connected to an operating handle 25, which is pivotably connected at pivot point 26 to the casing of the charger 33. A spring 27 is provided for returning the operating handle 25 from the closed position 6 to the open position 4.
Figure 5 shows the auxiliary charger of Figure 4 from a plan elevation, and illustrates how the generators are positioned so that they are driven in the correct direction in relation to the movement of the operating handle 25.
Cogged wheel 7 is connected to the shaft of generator 11 by a ratchet mechanism such that, in use, when the operating handle 25 is moved from the open position 4 to the closed position 6, rack element 31 rotates the cogged wheel 7, so that it drives the generator 11 in a clockwise direction. When driven in this direction, generator 11 supplies power to charging circuit (shown in Figure 8). However, when the operating handle 25 moves in the opposite direction, that is from the closed position 6 to the open position 4, the ratchet mechanism makes the cogged wheel 7 freewheel about the shaft, so that it does not drive the generator in an anticlockwise direction.
Cogged wheel 5, on the other hand, is connected to the shaft of its generator 9 by an opposite ratchet mechanism. When the operating handle 25 is moved from the open position 4 to the closed position 6, rack element 29 rotates cogged wheel 5, which is made to free-wheel about the shaft of generator 9, so that the generator 9 in not driven in an anticlockwise direction.
However, when the operating handle 25 moves in the opposite direction, rack portion 29 rotates the cogged wheel 5, which drives the shaft of generator 9 in a clockwise direction, thereby supplying power to the charging circuit.
Thus, the ratchet mechanisms and the positions of the generators are such that, in use, one generator is driven when the operating handle is pushed from the open position to the closed position, while the second generator is driven when the operating handle moves back to the open position.
According to this aspect of the invention, the auxiliary charger is operated by grasping the casing of the charger, and squeezing the operating handle with the fingers.
Figure 6 shows an auxiliary charger according to another aspect of the invention. As with Figure 4, an operating handle 25 is pivotably connected at pivot point 26 to the casing 33. A spring 27 is provided for returning the operating handle from the closed position to the open position. However, with this arrangement, the generators 9 and 11 are arranged such that cogged wheels 5 and 7 are rotated by a single rack element 35 which moves between the two wheels. The single rack element has teeth on first and second edges 34 and 36.
Cogged wheel 7 is connected to the shaft of generator 11 by a ratchet mechanism such that, in use, when the operating handle 25 is moved from the open position 4 to the closed position 6, rack element 35 rotates the cogged wheel 7, so-that it drives the generator 11 in a clockwise direction. When driven in this direction, generator 11 supplies power to charging circuit (shown in Figure 8). However, when the operating handle 25 moves in the opposite direction, that is from the closed position 6 to the open position 4, the cogged wheel 7 is made to free-wheel about the shaft, so that it does not drive the shaft in the anticlockwise direction.
Cogged wheel 5, on the other hand, is connected to the shaft of its generator 9 by an opposite ratchet mechanism. When the operating handle 25 is moved from the open position 4 to the closed position 6, rack element 35 rotates cogged wheel 5, which is made to free-wheel about the shaft of generator 9, so that the generator 9 in not driven in an anticlockwise direction.
However, when the operating handle 25 moves in the opposite direction, rack portion 35 rotates the cogged wheel 5, which drives the shaft of generator 9 in a clockwise direction, thereby supplying power to the charging circuit.
The electrical charging circuit is shown in Figure 8. A smoothing capacitor 17 acts to smooth the voltage generated by the generators 9 and 11. One terminal of the capacitor 17 is connected to the negative terminal of each generator, whereas the other terminal is connected to the positive terminal of each generator via diodes 35 and 37. The voltage across the capacitor 17 supplies the battery to be charged.
Figure 9 shows a mobile-phone 39-having an integral auxiliary charger according to the first aspect of the invention described in relation to Figures 1 and 2 above. The operating handle 1 is housed within the casing of the phone, and the user operates the auxiliary charger by pressing the pad 21 in a pumping action.
Figure 10 shows a mobile phone 39 having an integral auxiliary charger as described in Figures 4 to 6 above. The operating handle 25 is pivotably connected at pivot point 26 to the casing of the phone. The spring 27 is provided for biasing the handle towards the open position. In use, as the user closes and opens the handle 25, the rack elements 29 and 31 drive the generators so that power is continuously supplied to the battery being charged.
Although Figures 9 and 10 show the auxiliary charger employed in a mobile phone, the invention may equally apply to any other battery operated device.
Since the operating handles are biased by a spring to be in the open position, locking means may be provided to lock the operating handle in the closed position, thereby making it more compact when not in use.
