Description

SOLAR BATTERY CHARGER FOR MOBILE TELEPHONES The present invention relates to a solar battery charger which is directly made on a mobile telephone to detect the power of the batteries and then to charge the batteries by electric power being obtained from a solar collector panel when the power of the batteries drops below a predetermined level.
Various battery chargers are known and widely used for charging mobile telephones. These battery chargers may use AC power supply or car battery power supply for charging a mobile telephone through a rapid charging mode or a standard charging mode. When either battery charger is used, spare batteries still must be always provided for the mobile telephone so that the mobile telephone can be kept working constantly.
When the power of the batteries of the mobile telephone is not used up, the batteries cannot be charged or "battery memory effect" will occur. When "battery memory effect" occurs, the batteries may become useless.
During the charging process, if the standard charging mode is selected, much time (about one hour) will be wasted. When the rapid charging mode is selected, the charging time can be greatly shortened, however, the batteries may be overheated causing them damaged easily.
Furthermore, charging the batteries of a mobile telephone consumes much energy.
The present invention has been accomplished to provide a solar battery charger for mobile telephones which eliminates the aforesaid drawbacks.
According to one aspect of the present invention, a shell is molded on a mobile telephone to carry a set of batteries and a battery charging controller, and a solar collector panel is directly fastened to the shell for collecting the radiant energy of sunlight and then converting it into electric power, wherein the battery charging controller detects the power level of the set of batteries inside the shell and then charges the set of batteries by the electric power obtained from the solar collector panel when the power level of the set of batteries drops below a predetermined range.
According to another aspect of the present invention, a cover is detachably fastened to the shell of the solar battery charger on the mobile telephone and covered over the solar collector panel for protection.
According to still another aspect of the present invention, an additional folding solar collector panel is received inside the cover and electrically connected in series to the solar collector panel on the shell of the solar battery charger to collect the radiant energy of sunlight and then to convert it into electric power for charging the batteries.
The present invention will now be described by way of examples with reference to the annexed drawings, in which: Fig. 1 is elevational of a solar battery charger according to the present invention; Fig. 1-1 is a sectional view taken on line B B' of Figure 1; Fig. 1-2 is a sectional view taken on line A A' of Figure 1; Fig. 1-3 is a partial view in an enlarged scale taken on Figure 1-2; Fig. 1-4 is an elevational view of an alternate form of the solar battery charger of the present invention; Fig. 2 is elevational view of a solar collector panel according to the present invention; Fig. 2-1 is a partial view in section taken on Figure 2; Fig. 2-2 is a partial view in an enlarged scale taken on Figure 2; Fig. 3 shows a mobile telephone incorporated with a solar battery charger according to the present invention; Fig. 3-1 is a partial view in an enlarged scale taken on Figure 3; Fig. 4 is similar to Figure 3 but showing the folding solar collector panel spread out; Fig. 4-1 is a partial view in an enlarged scale taken on Figure 4; Fig. 5 is assembly and cross sectional views of the mobile telephone shown in Figure 3; Fig. 5-1 is a cross section taken along line A-A of Figure 5; Fig. 6 shows an alternate form of the cover for the mobile telephone according to the present invention; and Fig. 6-1 is similar to Figure 6 but showing the cover extended out.
Referring to Figures 1 and 2, the shell of the battery charger, referenced by 20, is covered with a solar collector panel 10 for collecting the radiant energy of sunlight and permitting it to be converted into electric power for charging the battery. The solar collector panel 10 comprises a plurality of recesses 120 distributed over the top and covered with a layer of transparent, water-proof film 110, a plurality of raised portions 121 distributed over the bottom corresponding to the recesses 120 and covered with a layer of transparent, water-proof film 111, two contacts 11 spaced at one side and extended out of the films 110;111. The recesses 120 define a respective concave surface 122 to collect the radiant energy of sunlight efficiently. When assembled, the contacts 11 are connected to the internal charging controller 1 inside the shell of the battery charger 20. The shell of the battery charger 20 comprises an AC power receptacle 21 and a plurality of indicator lamps 3 respectively connected to the internal charging controller 1. When the power of the batteries 2 inside the shell of the battery charger 20 drops below a predetermined level, it is detected by the internal charging controller 1, and then the radiant energy collected by the solar collector panel 10 is converted into electric power and sent through the internal charging controller 1 to charge the batteries 2.
Because the internal charging controller uses the same voltage to charge the batteries 2 as the power of the batteries drops below the predetermined level, the problem of "battery memory effect" is eliminated. The shell of the battery charger 20 may be variously embodied. Figure 1A shows an alternate form of the battery case. When the radiant energy of sunlight is not sufficient, AC power supply may be connected to the AC power receptacle 21 and controlled by the internal charging controller 1 to charge the batteries 2. The indicator lamps 21 are for BATTERY/LOW/CHARGE indications respectively.
Referring to Figures 3, 4, and 5, the battery charger 20 is directly molded on the mobile telephone 40 at the back. An additional folding solar collector panel 50 may be connected in series to the solar collector panel 10 on the battery charger 20. The mobile telephone 40 further comprises two fastening strips 41 (for example: velcro tapes) on two opposite long sides thereof for mounting a cover 30. When the folding solar collector panel 50 is folded up and closely received to the solar collector panel 10 on the battery charger 20, the cover 30 is fastened to the fastening strips 41 to protect the solar collector panels 10;50. When the cover 30 is removed from the mobile telephone 40, the folding solar collector panel 50 is spread out to collect the radiant energy of sunlight efficiently for charging the batteries 2 of the battery charger 20.
Referring to Figure 6, therein illustrated is an alternate form of the present invention in which the cover, referenced by 330, has one end fixed to one side of the mobile telephone 40 and an opposite end releasably sealed to an opposite side of the mobile telephone 40 by fastening strips 41. The cover 330 has a solar collector panel on the outside and contacts 151 on the inside. The contacts 151 of the cover 330 are connected to respective contacts 150 on the mobile telephone 40 as the cover 330 is closed on the mobile telephone 40, and therefore the radiant energy of sunlight can be collected by the solar collector panel on the cover 330 and converted into electric power for charging the batteries inside the mobile telephone 40.
