It is necessary to prevent the accidents mentioned above. Second problem It is necessary to simplify the structure of the electromagnetic switching device for switching a large current and to operate it reliably, but there is a problem that known means cannot be used. Further, since this device is placed in the engine room, it must be downsized and have heat resistance. Third
However, the electromagnetic switching device has a problem that arc discharge occurs due to the large electromagnetic energy stored in the cell motor and burns out, resulting in loss of practicality.

Operation: One terminal of the first and second batteries having the same voltage is commonly used, and the other terminals are independently provided. The sum of the capacities of the two batteries may be equal to or less than the capacities of the known automobile batteries. The use of a manual electrical switch that is opened and closed to drive the starter motor energizes the electromagnetic switching device with the outputs of the first and second batteries to activate the switching switch. By operating the changeover switch, the starter is started by supplying power to the starter motor from one of the first and second batteries. The headlight and other on-vehicle electric loads are energized by either the first battery or the second battery. Since the first and second batteries are charged during traveling, there is an action of preventing an accident in which the engine cannot be started. Therefore, there is an action for solving the first problem.

Since the electromagnetic switching device is switched in the early stage of driving the starter motor which requires a large current, there is a disadvantage that the stored magnetic energy of the starter motor is released and a spark discharge is generated in the switching member to burn it.

Since the copper plates 28a and 28b are pressed against the copper plate 19a at the same time during the switching operation, and thus spark discharge is prevented, spark discharge due to large accumulated magnetic energy of the cell motor can be prevented. Further, since the electromagnetic switching device is used in which the copper plate 19a and the copper plate 28a or the copper plate 28b are alternately pressed and brought into conduction each time the electromagnetic plunger is energized, the configuration is simplified, and a large current of the cell motor is reliably opened and closed. There are actions that can be performed. Therefore, there is an action for solving the second and third problems.

1 is an electric circuit diagram of an embodiment of the device of the present invention. In FIG. 1, reference numeral 1 is a well-known device for a generator driven by an automobile engine. Terminal 1a,
Three-phase AC output can be obtained from 1b and 1c. The diodes 8a, 8b, ..., 8c are three-phase diode bridge circuits. In the case of a known circuit, the output sides of the diodes 8a and 8c are connected to each other, and the side of the symbol 8-3 is a negative pole, and the sides of the diodes 8a, 8c, and 8e are a rectifier circuit capable of obtaining a positive pole output. In the device of the present invention, the + pole side is divided into two, the output side of the diode 8a becomes the + pole indicated by the symbol 8-1, and the symbol 8-2 side is the + pole on the output side of the diodes 8c and 8e and the symbol 8-. It is 2.

The output voltage at the terminals 1a, 1b, 1c is similar to a sine wave, but if it is a sine wave, it is shown as curves 22a, 22b, 22c in the time chart of FIG. Each curve shows the output voltage between a pair of terminals 1a, 1b, 1c. The fourth row of the graph in FIG. 5 shows the curves 22a, 22b, 22c on the same time axis. By rectifying these with a well-known three-phase diode bridge circuit, the direct current shown by the curve 23 is obtained. + Of diode 8a shown by symbol 8-1 in FIG.
The voltage between the output and the output indicated by the symbol 8-3 is the DC output indicated by the curve 25. Also, the diode 8 shown by symbol 8-2
The voltage between the positive output of c and 8e and the negative output of the symbol 8-3 is the DC output indicated by the curve 24.

In the case of an automobile, the outer shape of the on-vehicle battery 3 is the same as that of the conventional one, but it is composed of two sets of first and second batteries having an output voltage of 12 V and substantially the same capacity, and one container. It is stored in. The-pole terminal is common, and the + pole terminal is taken out independently. The − pole terminal is shown as symbol 5 and the + pole terminal is shown as symbols 6a and 6b. As will be described later, in the present invention, one of the two sets of batteries is selected to supply power to the load, and is independently charged by the generator via the + poles 8-1 and 8-2. . The one on the + terminal 6a side is called a first battery, and the one on the + terminal 6b side is called a second battery. Since the voltages of the + poles 8-1 and 8-2 are automatically adjusted to the set voltage, the charging current becomes small when one of the first and second batteries becomes overcharged. There is.

The block device shown by the dotted line A is an electromagnetic switching device including a changeover switch 9 and an exciting coil 9a. The block device indicated by the dotted line M is a starter motor 19 (dotted line display).
When the exciting coil 20 is energized, the electric switch 20a is closed, the starter motor 19 is driven, and the engine is started. Loads E, F, and G indicate vehicle-mounted loads such as headlights, room lights, window glass opening / closing devices, and the like. The object of the present invention can be achieved even if the first and second batteries are not separately housed in a single housing but separately mounted. The loads D, E, F, and G indicate vehicle-mounted loads such as an engine ignition device, a headlight, a room light, a window glass opening / closing device, and the like. The electric switches 18b, 18c, 18d are manual opening / closing switches for the loads E, F, G. In order to avoid overcharging of the battery 3, it is necessary to maintain the voltage at the terminals 8-1 and 8-2 at a set value lower than the voltage at the time when the battery is completely charged. The means for this will be described below. The voltage signals of the terminals 8-1 and 8-2 are input to the block circuit K via diodes. The block circuit K is a circuit that controls the field current of the generator 1 according to the above-mentioned input signal so that the signal becomes a set value. Therefore, regardless of the number of revolutions of the generator 1 and the size of the load. The voltage at the terminals 8-1 and 8-2 can be held at the set value. The means described above are well known means currently in use.

When the engine key is inserted into the key hole and manually rotated, the first electric switch 18 of the manual electric switch B of FIG. 1 is closed and the vehicle load D is energized in the first step. The load D is the ignition device of the engine. When the engine key is further rotated to the second stage position, the electric switch 18 is kept closed and the electric switch 18 is closed.
When a is closed and the engine key is springed back to the first stage position, the electric switch 18a is opened and the electric switch 18 is kept closed. Electric switch 18
When a is closed, the exciting coil 9a turns the diode 7c,
Since the electric power is supplied through 7d, the changeover switch 9 is changed over. Next, details of the changeover switch 9 will be described.

The use of the well-known means as the electromagnetic switching device 9 has the following drawbacks, which causes a burning accident and cannot be used. Since the exciting coils 9a and 20 are energized at the same time, energization of the cell motor 19 is started. When the terminals 2a and 2c or 2b are separated from each other, a large spark discharge due to release of accumulated magnetic energy of the cell motor causes a burnout accident. The device of the present invention is characterized in that the above-mentioned drawbacks are eliminated by a simple mechanism. The details will be described below.

In FIG. 3, the central portions of the rotary cams 24 and 25 are fixed to the rotary shaft 24a and rotate synchronously. The rotating shaft 24a is rotatably supported by a bearing (not shown) provided on the outer casing of the device of FIG. 3 fixed to a part of the automobile. What is indicated by the dotted line symbol C is a well-known electromagnetic plunger,
The excitation coil is shown in FIG. 1 as 9a.
Spindle 2 erected at the end of the actuator 26 of the electromagnetic plunger C.
A rotary lever 27 is rotatably supported by 6a, and an engaging pin 27a that is set up at the left end of the rotary lever 27 is attached to the rotary cam 2.
4 is in contact with the teeth of the shape shown on the outer peripheral portion. Eight teeth are arranged at an equal pitch. The rotating lever 27 is repelled in the direction of arrow R by a spring (not shown). The rotary cam 25 has a substantially circular shape as shown in the figure, and four projecting portions 25a, 25b, ... Are arranged at the same pitch.

The operation of the electric switch which is opened / closed by the protruding portions 25a, 25b, ... The temporary copper 19b is fastened to the substrate, and the bent portion 19a is bent upward. Terminal 1 from the copper plates 19b, 28a, 28b
4, 14a and 14b are derived. Copper plates 28a, 2
Details of 8b are shown in FIG. In FIG. 4, the base portions of the leaf springs 29a and 29b are support members 30 fixed to the substrate.
It is fixed to a and 30b by screws 31a and 31b, and copper plates 28a and 28b are fastened to the free ends by screws 32a and 32b. The free ends of the leaf springs 29a and 29b have the shapes shown in the figure, and are pressed by the protrusion 25a of FIG.
b is pressed against the copper plate 19a and is in the conduction mode.

When the electromagnetic plunger C of FIG. 3 is energized,
Since the actuator 26 reciprocates once, the teeth are engaged with the engagement pin 27a and the rotary cams 24 and 25 rotate 45 degrees in the clockwise direction of the arrow. The protrusion 25a (shown by the dotted line) in FIG.
9a is pressed to bring the copper plate 28a into pressure contact with the copper plate 19a. As can be understood from the above description, every time the electromagnetic plunger C is energized once, the copper plates 28a, 28
b alternately press-connects to the copper plate 19a. Leaf spring 29a,
It is necessary to adjust the shapes of the leaf springs 29a and 29b so that when the spring 29b springs back and the copper plates 28a and 28b are separated from the copper plate 19a, the gaps between the copper plates are equal and have a predetermined distance. For this reason, it is preferable to provide stoppers at the free ends of the leaf springs 29a and 29b to prevent excessive separation. The same purpose can be achieved by rotating the rotary cams 24 and 25 shown in FIG. 3 by set angles using a known rotary solenoid instead of the electromagnetic plunger C. The copper plates 28a, 2 of FIG.
Other means may be used as long as the mechanism 8b is elastically repelled so as to be separated from the copper plate 19a while being kept parallel to the copper plate 19a, and is held in pressure contact with both the protrusions 25a, 25b ,.

The exciting coil 9a shown in FIG. 1 is an exciting coil wound around the magnetic core of the electromagnetic plunger C shown in FIG. Therefore, each time the electric switch 18a of FIG. 1 is closed and the exciting coil 9a is energized once, the actuator 26 and the rotating lever 27 make one reciprocating stop, and the rotating cam 25 rotates by 45 degrees to stop. And hold. Therefore, the terminal 14 is
a or a switch that is alternately connected to the terminal 14b. The device described above is called an electromagnetic switching device. The terminals 14, 14a, 14b are the terminals 2a, 2b, 2c of FIG.
The outputs of the + terminals 6a and 6b of the battery 3 are alternately supplied to the load via the terminal 2a each time the excitation coil 9a is energized.

If the width of the protrusions 25a, 25b, ... In FIG. 3 in the outer circumferential direction is small, there will be the following problem. Copper plate 28a
Since and 28b are alternately brought into pressure contact with the copper plate 19a, when the copper plates 28a and 28b are separated from the copper plate 19a, the cell motor 19 has already been energized, so that the accumulated magnetic energy is released and a spark discharge is generated. Cause a burnout accident. The same accident occurs when the electric switch 20a of FIG. 1 is opened. However, although a known means for preventing sparks is adopted in the starter motor relay M currently used to prevent accidents, the description thereof will be omitted.
In order to prevent the above-mentioned copper plates 19a, 28a, 28b from being burnt out, the device of the present invention employs the following means.

Since the width of the outer circumferential portion of the projecting portions 25a, 25b, ... In FIG. 3 is made larger than 45 degrees, the projecting portion 25 is formed.
When a, 25b, ... alternately presses the copper plates 28a, 28b against the copper plate 19a, both copper plates 28a, 28b
There is a section in which 28b is pressed against the copper plate 19a at the same time. The width of the outer circumferential portion of each of the protrusions 25a, 25b, ... Must be a predetermined width that satisfies the above-mentioned conditions. As can be seen from the above description, the energization of the starter motor 19 is not interrupted during the switching operation, so that the spark discharge can be prevented from occurring. The number of teeth of the rotary cam 24 in FIG. 3 is 8
However, it can be implemented as 2n (n is a positive integer of 2 or more). In this case, the rotation cam 25 has no protrusion 25a, 25
The number of b, ... Becomes n and rotates by 360 / 2n degrees. The separation angle between the copper plates 28a and 28b is also 360 / 2n degrees. First
And a second battery has a large potential difference, the positive terminal 6a
If there is a potential difference between the terminals 6 and 6b and there is a circuit that short-circuits the terminals 6a and 6b, discharge occurs. Diodes 7c and 7d are inserted to eliminate this inconvenience.

Although the embodiment shown in FIG. 1 uses the-terminal as a common terminal, the present invention can be implemented by using the + terminal as a common terminal and the-terminal as two independent terminals. Next, the explanation will be given. In FIG. 2, the same symbols as those in FIG. 1 are the same members, and thus the description thereof will be omitted. As described above, in the present invention, one of the two sets of batteries is selected to supply power to the load, and is independently charged by the generator 1 via the three-phase diode bridge circuit. The one on the −terminal 5a side is called a first battery, and the one on the −terminal 5b side is called a second battery. As described above, the charging is performed by the same means as in FIG. 1, and the charging current becomes small when overcharged. Other means may be adopted as long as they achieve the above-mentioned purpose. The object of the present invention can be achieved even if the first and second batteries are not separately housed in a single housing but separately mounted. Only the discharged ones of the first and second batteries are charged, and when there is a difference in the output voltage of both batteries, the current flows through the terminals 6, 5a, 5b to perform charging and discharging. Can be prevented by the diodes 7d and 7c. In order to prevent overcharge of the first and second batteries, the same circuit as the block circuit K of FIG. 1 is also provided in FIG. 2, but it is omitted and not shown.

The block device shown by the dotted line A is an electromagnetic switching device including a changeover switch 9 and an exciting coil 9a. The block device indicated by the dotted line M is a starter motor 19 (dotted line display).
In the well-known relay for controlling the energization of the electric motor 20, when the exciting coil 20 is energized, the electric switch 20a is closed and the starter motor 1
9 is driven and the engine is started. Loads D, E, F,
G indicates an on-vehicle load such as an ignition device, a headlight, a room light, a window glass opening / closing device, and the like.

When the engine key is inserted into the key hole and manually rotated, the electric switch 18 of the manual electric switch B shown in FIG. 1 is closed in the first stage to energize the vehicle-mounted load D which serves as an engine ignition device. . When the engine key is further rotated to the second stage position, the electric switch 18 is held closed and the electric switch 18a is closed, and when the engine key is springed back to the first stage position, the electric switch 18a is opened. The electric switch 18 is kept closed. When the electric switch 18a is closed, the exciting coil 9a is energized via the diodes 7c and 7d, so that the changeover switch 9 is changed over. At the same time, the exciting coil 20 is energized to energize the starter motor 19.

Since the electromagnetic switching device A uses the device shown in FIG. 3, the terminals 14, 14a and 14b shown in FIG.
The electromagnetic switching device A corresponding to the terminals 2a, 2b, and 2c is constructed. Therefore, every time the exciting coil 9a of FIG. 2 is energized, the inputs of the negative terminal 5a of the first battery and the negative terminal 5b of the second battery are alternately input from the terminal 2a, and the on-vehicle electrical load E , F, G are energized. When the vehicle is driven in the mode in which the terminals 2a and 2b in FIG. 2 are connected, the output of the + pole terminal 6 causes the on-vehicle electric load to be energized via the terminals 2a and 2b. When getting off the vehicle and removing the engine key, then getting on the vehicle and inserting the engine key into the key hole, rotating the first stage and further rotating to the second stage, the exciting coil 20 of the relay M for driving the starter motor becomes The power is turned on and the engine starts.
At this time, if the amount of residual electricity in the first battery is small for the above-mentioned reason, the starter motor cannot be started, and the automobile engine cannot be started.

In the case of the device of the present invention, since the electric switch 18a of FIG. 2 is closed when the engine is started, the exciting coil 9a of the electromagnetic plunger C of FIG. 3 is energized and the terminals 2a are alternately turned on. It is connected to 2b and 2c.
When the vehicle is driven in the mode in which the terminals 2a and 2b in FIG. 2 are connected, the loads E, F, and G are energized from the + terminal 6 via the terminals 2a and 2b. At this time, the loads are not all energized, and if necessary, energization control is performed by the electric switches 18b, 18c, 18d for each load.

A load E is a headlight or other illuminating lamp, a load F is a room air conditioner, and a load G is a radio or other electric component. A load D indicates an electric component required for starting the engine, such as an ignition device. Since these components are energized through the diodes 7c and 7d, either the first battery or the second battery is completely discharged. Even in this case, there is an effect that does not hinder the engine starting. Although the electric switch 18 is closed, some loads are energized without going through the electric switch 18. For example, a clock. When you get off the car and remove the engine key, then get on the car and insert the engine key into the key hole and rotate only the first stage to close the electric switch 18, and further rotate to the second stage to close the electric switch 18a. To be Therefore, the load D enters the power supply mode, the exciting coils 9a, 20 are energized, the changeover switch 9 is changed over, the terminals 2a, 2c are connected, the electric switch 20a of the relay M is closed, the starter motor 19 is driven, and the engine is started. To start. The diodes 7c and 7d are
The excitation coil 9a is energized by the negative electrodes 5a and 5b of the battery.
This is for surely energizing the exciting coil 9a when the voltage of either the first battery or the second battery drops. As mentioned above,
Each time the engine is started, the first and second batteries are automatically replaced and used. When the headlights are turned on while driving and the battery is greatly consumed due to traffic congestion, when the driver forgets to turn off the lights while the vehicle is stopped and is left on, or when the battery is aging and the capacity is decreasing Then, when the engine is started, it becomes impossible to drive the starter motor,
The accident is commonly known as Battery Enco. The frequency of these accidents is extremely high, which is about one-half of the accidents in which the engine cannot be started. According to the device of the present invention, the first and second batteries are automatically replaced each time the engine key is turned to drive the starter motor, and the unused battery is charged during traveling, resulting in overcharging. Charging is stopped.

As can be understood from the above description, when the engine key is turned to drive the starter motor while the vehicle is stopped, the fully charged one of the first and second batteries is automatically operated. Since the starter motor is selected and used, the starter motor is always driven to prevent failure of engine starting. It is more effective to add the following means to the apparatus shown in FIGS. A device that detects a difference in output terminal voltage of the first or second battery being driven when the starter motor is driven, and turns on a lamp or generates an alarm when the detected voltage is set and is larger than the value. And If the battery is replaced or the generator is repaired when this alarm occurs several times, it is possible to prevent an accident in which the engine cannot be started due to a failure of the battery and the generator.

It is preferable that the capacities of the first and second batteries in FIGS. 1 and 2 are substantially equal, but the capacity of the second battery having a small charging capacity can be reduced. In general, the charging capability of the generator is sufficiently large, so that there is no practical problem even if there is a difference in the DC output between the three-phase diode bridges as described in FIG. In the case of a small ship propelled by an internal fuel engine, a device of the present invention can be an effective remedy, because if there is an accident with a battery engine, it will drift and be at risk of life. Even when the charging of one of the first and second batteries in FIGS. 1 and 2 is completed, the two output voltages of the three-phase diode bridge circuit are held at the set values. Therefore, since only the uncharged battery is charged, there is no inconvenience in use.

【The invention's effect】

First effect In the case of a car, when the driving condition changes, especially when there is traffic congestion at night and the battery is over-discharged and the headlights are left on for a long time, the starter motor cannot be driven during the next operation. Becomes It is possible to prevent the above-mentioned frequent accidents. A similar effect can be obtained for a traveling object using another internal combustion engine as a power source. Second effect It is possible to prevent burning of the switching member of the electromagnetic switching device A and damage to the battery. Third Effect The configuration of the electromagnetic switching device A can be simplified and a large current can be switched. Fourth Effect Since the three-phase diode bridge circuit indicated by symbols 8a, 8b, ... Is already attached to the rectifier circuit of the generator, the electromagnetic switching device A is added when implementing the device of the present invention. Only need be. Therefore, since it is sufficient to use a small-sized and inexpensive member, an effective means can be provided.
