Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

  The present invention relates to a business-use charger for mobile phones.

[0002]

[Prior art]

  Conventionally, in a coffee shop, a convenience store, or the like, 5 to 6 required for the charger from the power line 100V A dedicated charger containing a V AC adapter is provided at a specific location, Insert a coin, open and close the door with a key or PIN for theft prevention, and carry A mobile phone is connected so that it can be charged for about 20 minutes. Or as a store clerk And the mobile phone is being charged.

[0003]

[Problems to be solved by the device]

  This method not only requires complicated handling of the dedicated charger, but also charges the mobile phone. Electricity is limited to the place where the power line 100V is installed. From a management perspective, a full-time clerk is required.

[0004]

[Means for Solving the Problems]

  The present invention, for example, at a restaurant, a coffee shop, etc., charges a mobile phone by charging each customer's I was able to do it on the table. This includes new energy storage As a medium, a super capacitor with a capacity of tens of thousands of times that of an ordinary capacitor An electric double layer capacitor, hereinafter referred to as SC, is used as the capacitor type charging device according to claim 1. Customers can charge 5 to 10 electric appliances with an AC adapter and keep them on standby. At the customer's request, remove it from the AC adapter and rent it out If you connect it to a mobile phone, you can easily charge it. SC is a battery Compared to, charging / discharging can be performed 3 to 10 times faster than the current charger. It will be possible to charge the mobile phone quickly.

[0005]

[Embodiment of device]   In claim 1 of the present invention, as described above, SC is used as a storage medium for electric energy. , A new DC-DC converter with constant current and constant voltage functions It was a dense charger. This charger can be easily connected and disconnected from the AC adapter I made it possible to move, and when it was full of energy, it waited as it was. A slight voltage drop due to spontaneous discharge is always replenished. For example, in restaurants, coffee shops, etc. If there is an application for charging from the customer, remove it from the AC adapter and place it on the table. If you rent it out and connect it to the customer's mobile phone, it is not a 100V facility. By the way, it can be charged safely and easily. AC adapter is a constant voltage Consisting of RCC type switching regulator with current and low voltage function It See Figure 1

[0006] According to claim 2 of the present invention, a new capacitor type charger using SC is used at a time of 5 The racks can be plugged into one rack for connection and disconnection. You can attach the adapter and charge the SC from the power line with the AC adapter. This is a rack-type multiple charging device. See Figure 2

[0007]   The current SC is a single unit with a capacity of 50 F, F is an abbreviation for farad, and the applicable voltage is 2.5V to 2.7V, the diameter is φ18, and the length is 40mm. , 2 to 4 in parallel as shown in FIG. 3, or as shown in FIG. Parallel connection is made by connecting 2 to 4 stages in series for parallel and direct combination. Multi-stage connection Then, the voltage of each stage will vary and loss will occur. Apply the voltage above and attach the trim circuit. See Figure 6

[0008]

[Effect of device]

  As described above, the SC-type condenser type mobile charger can be used for 5 to 10 at a time. Insert the stand into a rack-type multiple charging device to charge it, and register at a restaurant, coffee shop, etc. Installed near the battery charger and rack type capacitor charger according to customer's request Multiple charging devices can be pulled out and rented out to customers. You can safely and easily charge your own mobile phone even where V is not installed.

[0009]   In the rack type charging device, the AC adapter was attached to each stage as described above. However, attach this to an AC adapter with the capacity to cover 5 to 10 units at a time. The output to each stage and a linear constant current and voltage circuit at the end. Allow the SC to charge as well. This will further increase reliability.

[0010]   Although it depends on the mobile phone manufacturer, the upper limit of charging voltage is set to, for example, 4.9V. If specified, booster DC-DC converter with 2 to 4 SCs in parallel with output 4.8V Attach the barter to the SC and connect it to the customer's phone as a unit to charge the mobile phone. To turn it on.

[0011] When two SCs are connected in series, the voltage applied from the AC adapter to the SC is 5.4. Set to V and attach a boost DC-DC converter with 4.8V output in the same way.

[0012]   In the case of 3-4 stages in series, the maximum voltage of SC is 7.5V and 10V, and the minimum value is , 1.5V. From now on, in order to output 4.8V, the zeta type buck-boost Type DC-DC converter is used.
