Description

[Detailed description of the invention] Mobile case assembly technology field for portable electrical devices The present invention generally relates to carry case assemblies for portable electrical devices. Regarding e-assembly, for more details, please refer to The present invention relates to a mobile case assembly including a battery that supplies a battery.

Background technology Portable battery powered electrical equipment applications require high capacity and small size batteries. ing. Portable battery-powered hand tools, portable radio devices, pagers, portable Lula phones and other similar portable electrical devices all have high capacity, small batteries. It is advantageous. The higher the battery's energy storage (capacity), the faster the battery can be recharged. This also increases the amount of time a user can use the device without having to replace it.

In the field of portable radio equipment, the need for high capacity batteries is critical (e.g. (police officers, fire brigade, etc.).

The main problem with high-capacity batteries is that they are generally larger than standard-capacity batteries. It's a heavy thing. The larger the battery used in the communication device, the larger the battery. The increased weight and dimensions of the device make it less portable for the user. The need for high-capacity batteries for communication equipment has been driven by recent improvements in the performance of route equipment (i.e. , adding a synthesizer (syn + hesizer), increasing the use of microprocessors, etc. ) has been increasing in recent years. Recent multi-functionality of communication devices is due to these devices. This significantly increases the flow loss of You need a lot of battery.

Most portable communication devices, such as portable radio devices, are carried in carrying case assemblies; This is typically attached to the clothing of the user of the wireless device. Mobile phone security allows the wireless device user to store the wireless device while engaged in other activities. It becomes possible to keep it. A wireless device is kept in a carrying case for most of its use. -Tends to be carried within the assembly. Users of wireless communication devices must Remove your wireless device from your phone case only if you want to talk to it to send messages. It is common to take it out. When a wireless device is placed in a carrying case, the wireless device's battery A carrying case assembly that increases battery capacity would be extremely advantageous. This results in The battery life of mobile communication devices can be extended while maintaining the size of the communication device battery. hold or make smaller. No electrical energy is supplied to the wireless device while it is in the carrying case. It would be extremely advantageous to have an additional battery source capable of supplying .

Summary of the invention A carrying case capable of supplying electrical energy (current) to a portable electrical device according to the invention - Assembly is provided.

In one example of the invention, the carrying case assembly includes a Contains a battery held in the battery. This battery is used when the communication device is housed inside the carrying case. Once connected, the portable electrical device is connected to a set of contacts that contact the portable electrical device.

This allows Panteli to supply electrical energy to electrical devices. Become.

In another example of the invention, the carrying case assembly is connected to a rechargeable battery. It has two sets of tangents and v. One set of contacts mates with the mobile communication device and connects the battery. power the device. The second set of contacts allows you to battery (assuming this battery is rechargeable) Once housed in the assembly, it can be charged with a battery charger.

Since it is a voltage, current flows to the battery within the wireless device 110. These two bags The voltage difference between the two terminals can be adjusted by using a conventional input voltage adjustment circuit. 2B shows terminal points 220, 2 corresponding to the second set of contacts 112 in FIG. 1B. 22, 224, 226 are shown. The second set of contacts 112 is connected to the battery. 202 is rechargeable, such as a NiCd (Nokel Cadnium) battery. , is used to connect the battery 202 to a battery charger (not shown).

Other types of rechargeable batteries may also be utilized with the present invention. Also, alkaline or or other similar types of non-rechargeable batteries may also be utilized with the present invention. non-refill Electric types are not preferred in this invention because they cannot be recharged. battery 202 positive A diode 212 connected between the terminal and terminal point 220 has a selected polarity. , thereby discharging the energy of battery 202 to a battery charger (not shown). prevent from doing. Terminal point 224 is electrically connected to the negative (ground) terminal of battery 202. Combined so that it can be connected to a battery charger. The negative terminal of the battery 202 and An optional coding resistor connected between terminal point 222 sister) 214 informs the battery charger of the capacity of 7<noteri 202. It can be used to The value of resistor 214 is determined so that the charger has the appropriate amount of charge for the battery. Instruct the charger about the capacity of the battery 202 so that it can send information. randomly selected. For example, assign resistor 214 a value of 1000 ohms. and the battery 202 is 10 Q Q m a H (milli-amp-hou rs), it notifies the device of the charge. A charger that can be coupled to terminal point 222 is The value of the resistor 214 is detected, the capacity of the battery 202 is determined, and the terminal points 220, 22 are Send the appropriate amount of charge flow through 4. A battery charger couples to battery 202 If so, it determines when it is appropriate to stop charging. To facilitate this determination, a thermistor coupled between negative battery terminal (ground) 224 and terminal point 226. A battery 202 is provided with a battery 202 . As the battery continues to charge, The temperature of the battery increases until it reaches a temperature at which charging is completed. above this temperature This indicates that the battery is overcharged and may actually damage the battery. There is. To prevent such overcharging, a charger (not shown) is connected to terminal point 226. The charger can detect the thermistor's resistance and determine the battery temperature. That's what I do. The battery is fully charged! The battery temperature has been reached indicating that If the charger determines that this is the case, charging will be stopped. Second set of contacts 112 ( 220, 222, 224, 226) are designed to make it easier to store the mobile case in the charger. It is preferable to arrange it on the back side of the housing 108 in order to make it more compact. contact 112 mate with similar contacts on the battery charger. mobile case 2 The battery 202 housed in 00 and the battery in the communication device can also be charged at the same time. It is preferable to be able to do so. This means that the communication device 110 is placed in the mobile case 200. This can be done by inserting the mobile case 200 into the battery charger. Ru.
