JP3051954U - Charger with charge speed switching function for mobile phones - Google Patents

Abstract

(57) [Summary] [Purpose] In charging a mobile phone, the user selects a charging rate according to the situation, and does not impose an unnecessary burden on the battery. Keep it long. In addition, it is designed to be portable or for use in cars, and it can be used outdoors, eliminating "call out" and "standby failure" due to unexpected battery exhaustion. [Structure] A dry battery (7) inside a main case (5)
There is a terminal (4) for connecting and holding in series, a charging speed changing circuit (2) and a switch (1) are connected to this terminal, and a connector (3) for charging the mobile phone is provided. .

Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The idea is that when a low battery warning is displayed while using a mobile phone, simply connect the product to the mobile phone and continue talking. Furthermore, we provide a mobile phone charger that does not become overcharged even if you forget to remove the product after the call ends, and you can select the charging speed as needed.

[0002]

[Prior art]

 Conventional chargers for mobile phones include an automatic charger that can detect several different voltages by detecting the voltage of the battery to be charged using an electronic circuit, and a charger that is dedicated to one type of voltage. Neither of these options allows you to arbitrarily determine or select different charging speeds, or times to end charging. Generally, the faster the charging speed, the shorter the life of the battery being charged. Previously, it was not possible for the user to choose between “charging speed” and “battery life” with a single charger.

[0003]

[Problems to be solved by the invention]

 This is a battery charger that can be used instead of the dedicated charger provided with the mobile phone when the battery power of the mobile phone is insufficient in places where household power cannot be used. If urgent rapid charging is required, choose a method even if the battery life is short, and if it is not so urgent, use a function switch such as charging with a small current to keep the battery life long. People can choose.

[0004]

[Means to solve the problem]

 The present invention solves the conventional disadvantages in the following way. (B) The power supply for charging is AAA type, AA type, or AA type dry batteries, each of which is connected in series to obtain the specified voltage. (B) In the case of a charger that uses an automobile battery as another power source, a predetermined voltage is obtained using a voltage drop circuit. (C) In order to obtain several different charging rates, several circuits that determine the electrical resistance and voltage suitable for each rate are assembled to form a charging rate changing circuit (2). (D) A desired charging speed is obtained by switching the switch (1) connected to the charging speed changing circuit (2). (E) The charging speed is manually selected by the charger user according to the situation.

[0005]

[Action]

 This device provides a function that allows the user to arbitrarily select one of several charging speeds, such as auxiliary power, normal charging, rapid charging, and emergency charging, when the battery level of the mobile phone is insufficient. Provide a charger with

[0006]

【Example】

 The example of this invention is described. (B) As shown in FIG. 1, a terminal (4) for connecting several dry batteries in series is provided inside a case (5) having a battery cover (6) so that the dry batteries (7) can be taken in and out. And a switch (1) connected to the charging speed changing circuit (2) and a connector (3) connected thereto. (B) As shown in FIG. 2, instead of the dry battery (7), a vehicle power plug (8), a connection line (9), and a voltage drop circuit (10) following the vehicle were provided. The charger with the charging speed switching function described in the example (a). (C) As shown in FIG. 3, the charger with a charging speed switching function according to the embodiment (b), wherein the power plug (8) for an automobile and the case (5) are integrated. (D) A portable / vehicle type, comprising a dry battery (7) and a voltage drop circuit (10) in parallel, and a detachable power plug (8) and connecting wire (9) for a vehicle. A charger with a charging speed switching function according to the embodiment (a) of the type.

[0007]

[Effect of the invention]

 Carrying the product in your car or leaving it in a car will help prevent calls from being cut off due to insufficient battery power in your mobile phone, or prevent you from being able to stand by. Furthermore, by selecting a charging rate that suits the situation, it is possible to reduce the burden on the battery of the mobile phone more than necessary, and to extend the battery life of the mobile phone.
