[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dedicated power supply for operating an on-vehicle audio device by supplying operating power only by a dedicated battery by operating an operation switch provided in a current control circuit only when the engine is stopped. The present invention relates to a simple power supply system for a vehicle-mounted audio device or the like using a battery. The present invention is applied to a general vehicle in which an in-vehicle audio device or the like does not operate when an engine key is turned off, and includes a hybrid car using an electric motor in combination.

[0002]

2. Description of the Related Art Many conventional ordinary vehicles operate an on-vehicle audio system without stopping the engine or operating the engine when parking, and external audio equipment or the like powered by a vehicle cigar socket or a vehicle accessory socket. In order to operate the vehicle, the main operation power was supplied by inserting the engine key and setting the key to the ACC position.

[0003] In addition, most on-vehicle audio devices of ordinary vehicles often store the frequency set for each channel of a radio or television station, or set the volume, sound quality, clock, etc. once, regardless of whether the engine key switch is ON or OFF. It is equipped with a semiconductor memory circuit for holding the information storage until reset or set, and constantly supplies a small current from the main battery mounted on the vehicle for storage maintenance. Does not work, it is a device equipped with one more circuit, and only supplies the main operating power when ACC or ON from the engine key switch circuit. When the engine was stopped, insert the engine key and move the key to the ACC position. There was not actuated by supplying a main hydraulic power.

[0004] The on-vehicle audio system includes one circuit for continuously supplying a small amount of power for storing and holding the semiconductor memory circuit, and one or more circuits for supplying operating power. When the main operating power is supplied from one circuit passing through the circuit, and when the auxiliary power for operating is also supplied from another circuit such as a semiconductor memory circuit automatically by the function of the in-vehicle audio device etc. There is also an on-board audio device that starts to operate, and when the engine key switch is ACC or ON, only the main operating power is supplied, and the on-board audio device and the external audio device etc. were activated from the on-board cigar socket, so when the engine was stopped Then, the engine key is inserted, the key is set to the ACC position, and the main operating power is supplied to operate the key.

In many ordinary vehicles, when power is taken in from a vehicle-mounted cigarette socket or a vehicle-mounted accessory socket with a power plug for a cigarette socket while the engine is running, power is naturally obtained by turning off the engine key switch. If the power is interrupted or turned off without taking measures to back up the power in a running PC, word processor or VCR, etc. The engine is stopped and the engine key is set to the ACC position.
If the onboard cigar socket or onboard accessory socket is used as a power source while the engine is running, the operating status must be checked each time before stopping the engine.In some cases, forget to check the operating status. The engine may be stopped, and sentences during the operation of the PC may be erased instantaneously.

In a special vehicle such as a camper, an auxiliary battery is mounted separately from the main battery mounted on the vehicle, and power from a generator (alternator) is used by using an isolator so that the main battery and the auxiliary battery do not become parallel. There is a device that branches and charges the auxiliary battery, and it is used as a power source for operation such as on-vehicle electrical components.Some car supply stores etc. also provide a traveling charging kit that can easily charge the auxiliary battery. Although they are sold as parts or kits with a set of parts, they are all expensive and require specialized knowledge to be mounted later on a general vehicle, and are dangerous for general people to mount and cannot be handled easily.

[0007] In a general vehicle, a dedicated battery for supplying operating power to an in-vehicle audio device and an external audio device or the like while the engine is stopped is not mounted on the vehicle, and a simple power supply system is not provided. Since it is not equipped, an engine key is always required to stop the engine or to operate the on-vehicle audio device or the like when parking, which is inconvenient.

In general vehicles, there is a portable battery that can be charged by taking in power from a vehicle-mounted cigarette socket or a vehicle-mounted accessory socket with a power plug for a cigarette socket while the engine is running, but is used as a simple power source outdoors. When the main power is not supplied due to the removal or exhaustion of the main battery in the vehicle when the engine is stopped, the memory etc. of the preset channel of the in-vehicle audio device will not be reset. Although there was an auxiliary battery system to keep it, as in the present invention, the dedicated battery is always automatically charged while the engine is running, and when the engine is stopped, the operation power can be supplied only from the dedicated battery with easy operation And a simple power supply system for operating on-vehicle audio equipment, etc. It was bought. (For example, see Japanese Patent Application Laid-Open
No. 2252)

Further, in a general vehicle, if the room lamp and the hazard lamp are continuously turned on without stopping the engine or operating the engine when parking, the main battery of the vehicle is consumed and it becomes difficult to start the engine. When turning on the hazard lamps and turning on the room lamps during auto camping and fishing, the engine was operated and turned on.

[0010]

As described above, in many ordinary vehicles, the main operating power supply to an on-vehicle audio device or the like is turned on or off by an engine key switch, and the vehicle is automatically turned on while the engine is running. The on-board audio device and the like are activated by the power supply from the main battery, but if the engine is stopped or the engine key switch is kept in the ACC position while parking, the main battery on the vehicle will rise and it will be difficult to start the engine. Troubles such as occur.

[0011] If the vehicle is idling at the time of parking, the problem of running out of the main battery of the vehicle is solved, but further problems occur, such as air pollution by exhaust gas, engine noise, and fuel consumption. Auto booms, fishing, picnics, outdoor barbecues, and other outdoor use of on-board audio devices have become popular, and environmental destruction has become a social problem.

Further, in many general vehicles, a personal computer which operates while taking no backup measures by taking in power from a vehicle-mounted cigarette socket or a vehicle-mounted accessory socket with a power plug for the cigarette socket while the engine is running.
Even if you are in the middle of recording with a word processor or VCR, even if you turn off the engine key switch without checking the operating status each time, the operating power will continue to be supplied from the dedicated battery without interruption. This means that the operation can be performed stably without instantaneously turning off the PC screen during operation or disturbing the video screen.

Accordingly, the present invention does not require the main operating power and the operating auxiliary power from the engine key and the main battery mounted on the vehicle when most of the ordinary vehicles stop the engine. No idling for the purpose of operation is required, and a system that can be easily attached to ordinary vehicles later is also invented, so that the main operating power supply to the in-vehicle audio device etc. can be easily turned on using only the dedicated battery. The present invention provides a simple power supply system such as an in-vehicle audio device using a dedicated battery that is provided with an operation switch that can be turned off.

Further, even if the room lamp and the hazard lamp are turned on without stopping the engine when the engine is parked or the vehicle is parked, the interior lamp of the vehicle is not affected at all even if the main battery of the vehicle is exhausted. Is to be able to light up with confidence.
