Description

  The present invention relates to an apparatus for preventing a voltage drop by suppressing a natural discharge of a power battery mounted on an agricultural machine such as a cultivator, a tractor, or a combiner, and a transport machine such as an automobile or a motorcycle.

Agricultural machinery represented by cultivators, tractors, combines, etc., and transportation machinery such as automobiles, motorbikes, pleasure boats, etc., supply electricity to the cell motors from the installed power battery when starting the engines. Is activated.
When starting the engine at the time of starting, it is necessary to supply a voltage higher than a certain level to the cell motor to the power battery, but the power battery discharges and decreases the voltage even in the absence of an electrical load. I am letting.

  In particular, it is used only during busy seasons such as agricultural machines, and except for that period, it is stored in a garage or warehouse and left in a neglected state, so the voltage of the power battery drops. Even with a private car, if you do not use the car for a long period of time, such as when you leave the house for a long trip or use it only on the weekend, the power battery discharges and the voltage drops when you want to use it. The engine may not start.

  Furthermore, the voltage of the power battery decreases as the temperature decreases, which may hinder engine starting. In particular, a voltage drop is likely to occur in a cold region, and particularly in winter.

  Therefore, in response to such a voltage drop due to the discharge of the power battery, in cold regions, the capacity of the power battery is increased as a cold region specification, but in regions other than the cold region, the wire terminals are removed from the power battery. For example, a method of electrically insulating the power supply battery or a method of removing the power supply battery itself from the agricultural machine or the transport machine is used. In particular, the method of removing the power supply battery itself is effective for preventing theft of agricultural machinery and transport machinery.

  However, the work of removing the wire terminal from the power battery as described above is performed by loosening the wire terminal mounting bolt attached to the electrode post of the power battery in a narrow engine room where various devices are mounted. This is a difficult and troublesome task due to interference with other equipment and parts in the engine room. For this reason, it is left without being removed, leading to a voltage drop of the power battery.

  On the other hand, the method of removing the power battery is generally difficult for a normal person to remove and carry because the installed power battery is heavy, except for a motorcycle.

  Therefore, the object of the present invention is to prevent a voltage drop due to leaving the power battery for a long period of time easily even in an engine room that is difficult and difficult to work on such as agricultural machinery and transport machinery, and the engine always starts the power battery. It is an object of the present invention to provide a power supply battery switching type power supply connector switching device used for preventing the voltage drop of the power supply battery kept in an easy state and preventing theft of agricultural machinery and transport machinery.

  The invention according to claim 1 is a connector comprising a first connector terminal having a mounting portion to a negative electrode terminal of a power battery and a second connector terminal movable so as to be fitted to the first connector terminal; A connector movable device comprising: a passive portion connected to the first connector terminal; and an active portion connected to the second connector terminal and adapted to fit the first connector terminal and the second connector terminal; A switching unit for operating the connector movable device to switch the connector from an energized state to an insulated state or from an insulated state to an energized state, and a verification information receiving unit for operating the connector movable device. A control device comprising a control unit that collates collation information stored in collation information and outputs control information to the switching unit, and a transmission key that sends the collation information to the receiving element. A power supply battery-mounted power connector switching device.

  The invention described in claim 2 is a power supply battery voltage drop prevention device comprising the power battery mounting type power connector switching device described in claim 1.

  The invention described in claim 3 is an anti-theft device for equipment equipped with a starting power supply battery comprising the power supply battery-mounted power connector switching device described in claim 1.

  By attaching the power battery switching type power connector switching device according to the present invention to the power battery of agricultural machinery such as cultivators, tractors and combines, and transportation machinery such as automobiles, motorbikes and pleasure boats, it can be left for a long period of time or outside temperature. In the winter when the power supply becomes low, it is possible to prevent the voltage drop due to the self-discharge of the mounted power supply battery very easily, and always maintain the usable state. In addition, it is possible to easily attach and remove the connector as a countermeasure against electric discharge in a small engine room.

  Furthermore, the present invention can operate the power connector switching device attached to the power battery by remote control from the outside, and this remote control can be performed by an unjust means from the state of taking measures against discharge once in an insulated state. It is difficult to start the agricultural machine and the transport machine except for obtaining the above function, and it has a great effect in preventing theft.
