Description

A combined engine for a single engine,

The present invention is a technique of using an engine mounted on a vehicle as a vehicle in normal operation and also used for operation of a generator at the time of stopping.

Generally, the engine for generator and the engine for vehicle operation are used independently. This is because the control variables such as the accelerator are different and the mechanical connection structure is fixed. For this reason, for example, even a portable generator, the generator and the engine are fixedly coupled.

In recent years, modernization of rural areas and fishing villages has accelerated and demand of using electric power tools has been demanded. However, it is not easy to provide electric power every time according to electric power demand in an unspecified place among a wide range of work sites. For example, it is necessary to supply power while carrying a portable generator. Furthermore, it is even more difficult to supply power lines with commercial power.

Sometimes we can think of moving generators with generators, but the vehicles can not cross the fields, and the sandy beaches of fishing villages can not be operated unless they are dedicated 4WD vehicles. Also, it is not easy to get on and off the generators here, and there is a fear that the generators may be stolen if left unattended because it is troublesome to get on and off.

Since the farming and fishing village has entered the mica period, one worker often drives the vehicle and works. In this case, there is a characteristic that the operation of the vehicle and the electric power such as the generator are alternatively used. That is, if each engine is provided independently, it means that it causes waste of resources.

This problem can be summarized as follows.

1) Generally portable generators have inconvenience to get on and off the car, and in case of large power generation capacity, it is necessary to mobilize separate loading and unloading equipment (crane, etc.) due to its weight.

2) When one person performs the operation and the field work, there is a problem of inefficiency that one of the generator or the vehicle engine equipped with the individual engine becomes idle.

3) Although it is conceivable to construct a structure in which the power of the generator and the vehicle are interlocked with one engine, in this case, there is a problem that the generator system that is not used increases the unnecessary burden on the operation of the vehicle, thereby deteriorating the efficiency of the engine. Particularly, the generator uses a governor for automatic control of the engine speed according to the variation of the load. As the governor, there is a risk of a sudden accident if the engine is started during normal rotation. Therefore, it is difficult to consider a configuration in which two loads are fixedly connected to one engine in parallel in a normal operation.

If a single engine can be used alternately for generator and vehicle operation under safety-enhanced conditions, it is possible to prevent an accident caused by moving the vehicle while the generator is being used, do. The present invention is a new concept conceived in this concept.

A first object of the present invention is to provide a multipurpose use environment in which one engine is optimized for driving and power generation of a vehicle under safety-enhanced conditions.

It is a second object of the present invention to provide a technical means for minimizing the mutual coherence so that the operation of the generator is not an obstacle to the running of the vehicle.

It is a third object of the present invention to provide a technical means for minimizing the mechanical structure and weight required for generating electric power to generate stable electric power and minimizing the burden of vehicle operation.

It is a fourth object of the present invention to provide a technical means for reducing the mechanical cost and the power efficiency by reducing the length of the power line by providing mobility to place the generator as close as possible to the work place.

According to an embodiment of the present invention,

A generator mechanism (2) of a structure coupled to produce power by the power of the engine;

An engine (3) operatively coupled to the vehicle drive mechanism and the generator mechanism;

A switching connection mechanism (4) selectively coupling the power of the engine (3) to the vehicle drive mechanism (1) or the generator mechanism (2);

Characterized in that the engine (3) having a single structure is selectively selectively interlocked with the vehicle drive mechanism (1) or the generator mechanism (2) by selective interlocking action of the switching connection mechanism (4).

Here, the switching connection mechanism 4 may be configured to control the connection to the generator with an electrically controlled or mechanical gear box such as a magnet switch. In this case, the switching connection mechanism 4 configured by a mechanical gear box may further include a mechanism for mechanically controlling the vehicle so that the vehicle can be driven only in the neutral position of the gear box.

Furthermore, the magnet switch or the switching connection mechanism (4) which controls mechanically can be configured to shut off the generator output at the output of the moving sensor that senses the movement of the vehicle, Current or voltage) sensor can be configured to transmit power from the no-current output of the sensor over a certain period of time to the drive side of the vehicle. It is also possible to mechanically detect whether or not the power cord is inserted and transmit the power to the drive side of the vehicle . Furthermore, the switching connection mechanism 4 may be controlled in association with the start motor of the vehicle.

In addition, the generator mechanism 2 may include an electronic or mechanical governor that senses the extent to which the generator output power is supplied to the lower stage and automatically stabilizes the engine output. In this case, It may also include a configuration that automatically decelerates the generator governor.

In addition, the generator mechanism 2 is provided with an electric power distributing mechanism for outputting electric power to the output port in a stable state at an engine rotation speed of 3600 rpm (or 1800 rpm) of the vehicle or in a stable state in a power frequency range of 45 Hz to 65 Hz (preferably 50 Hz or 60 Hz) And may further comprise control means.

In addition, the generator mechanism 2 may include a switchboard structure for inserting a filter for shaping a waveform such as a voltage fluctuation and a surge generated in rotation of the engine.

Further, when the remaining amount of the fuel in use of the generator becomes equal to or lower than a predetermined level (for example, 5 liters), the generator mechanism 2 or the switching connection mechanism 3 uses an amplifier, a warning lamp, a hazard lamp, It is preferable to include a configuration for generating an alarm.

Further, the generator mechanism 2 is constituted by an alternator installed in the bonnet, and a rectifier and a battery serving as a filtering function are connected to the output of the alternator, and an inverter is connected to the output of the rectifier and an unstable output of the alternator interlocked with the engine The battery may be filtered and supplied to the inverter, and the output of the inverter may be connected to the governor and drawn out to a power outlet for use.

In addition, the vehicle driving mechanism 1 may be configured to be able to operate a field or a sandy field for agricultural use or fishing, and the switching connection mechanism 3 may be constructed by using a flexible coupling (joint) Can be structured so as to maintain a stable engaging operation even when the vehicle is operated in conjunction with the vehicle (3) and the shape of the vehicle changes to some extent.

Further, when the switching connection mechanism, the generator mechanism, and the engine are interlocked, the connection system of the engine and the generator mechanism is activated by detecting the use request of the generator, while the power consumption is sensed to increase or decrease the power, And < / RTI >

In a more detailed configuration, the generator mechanism is a second generator for generating electric power. The generator is connected to a pulley of an engine crankshaft together with a first generator for driving to constitute a hardware connection capable of receiving power, The hardware connection point is executed as the power transmission to the first generator only in the use operation state of the second generator and the power of the engine is controlled in accordance with the degree of use of the second generator power in the power transmission state .

In this software configuration, the air conditioner is interlocked on the assumption that the power transmission to the second generator is interrupted at the moment when the power of the engine is transmitted to the air conditioner, or the power of the engine is sensed by the ECU to increase the power of the engine to 3,600 rpm Up to 1,800 rpm) or the basic engine operation condition may be adopted.

The present invention has the following effects.

1) Since a single engine can be alternatively used as a switching connection mechanism alternatively, it is possible to reduce the facility cost and prevent the unused generator from adversely affecting the engine load at the time of driving the vehicle.

2) It is possible to prevent danger due to change of generator power supply system by detecting (automatically) the use state of electric power and the operation intention of the vehicle and controlling the warning or power mechanism (interception), and further, It is possible to prevent a sudden vehicle accident in the state.

3) The inconvenience of getting on / off the generator can be solved and the generator can be accommodated in the bonnet, thus securing the safety from the theft of the generator.

4) By providing a flexible flexible joint in combination of generator and engine if necessary, it is possible to freely install the generator in a position that does not damage the function of the vehicle, and furthermore, There is an effect that the engagement state can be automatically maintained even if the interlocking position is somewhat changed.

5) adopting a structure that adds a new software principle by using a conventional hardware principle such as a pulley mechanism that links the power of the engine, there is an eco-friendly effect that can be easily applied to the field.

BRIEF DESCRIPTION OF THE DRAWINGS The above and other objects, features and advantages of the present invention will be more apparent from the following detailed description taken in conjunction with the accompanying drawings, in which: FIG.

1 illustrates an example of a vehicle for a farming and fishing village to which the present invention is applied. Particularly, the present invention adopts a structure that can be used in various fields such as running in a farm field or in a rice paddy field or in a fishing village. This is to shorten the length of the power line, in particular, to prevent the loss of power from the power line and to minimize the need for troublesome operation due to the long power line. Therefore, the present invention is also applicable to a car or a dump vehicle.

FIGS. 2, 3 and 4 are schematic diagrams showing the basic concept of the present invention and interlocking concept.

A vehicle drive mechanism (1; 1-1, 1-2, 1-3) of a structure that is configured to drive the vehicle by the power of the engine;

A generator mechanism (2) of a structure coupled to produce power by the power of the engine;

An engine (3) operatively coupled to the vehicle drive mechanism and the generator mechanism;

A switching connection mechanism (4) selectively coupling the power of the engine (3) to the vehicle drive mechanism (1) or the generator mechanism (2);

The engine 3 is selectively selectively interlocked with the vehicle drive mechanism 1 or the generator mechanism 2 by a selective interlocking operation of the switching connection mechanism 4. [

In each component,

The 'vehicle drive mechanism 1' having a structure in which the vehicle is driven by the power of the engine 'includes a transmission, a differential gear 1-1, a steering device 1-2, , A suspension device (1-3), etc. (see Figs. 2 and 3). Therefore, the vehicle drive mechanism 1 of the present invention means an assembly of various power mechanisms for operating such a vehicle.

Particularly, in the present invention, the vehicle drive mechanism includes a structure capable of traveling a field or a sandy field for agricultural use or fishing, in order to obtain an effect of supplying electric power without shorting efficiency as a short power line at a nearest distance. As the power line becomes longer, the efficiency is lowered due to the voltage drop and the like, resulting in a waste of resources such as energy.

The term " generator mechanism 2 combined with the engine to generate electric power by power of the engine " means a power generating motor for generating electric power, an electric switchboard and a cable connector. A general power generation motor is driven by being fixedly connected to the engine but in the case of the present invention, the power generator 1 and the generator mechanism 2 are selectively connected to one engine 3 and driven. And has a different structure and effect from the conventional art in that it has the configuration of the switching connection mechanism 4 in which the driving part in the event of inactivity is connected or disconnected (refer to FIG. 3 and FIG. 4).

The 'vehicle driving mechanism and the engine 3 that is powerfully interlocked with the generator mechanism' means a mechanical structure, such as an internal combustion engine, generating rotational force by using diesel, gasoline, gas, or the like as fuel . Since the vehicle can be driven by this engine, it is understood that it is the most basic configuration, and thus includes all components such as an internal combustion engine and the like provided at least in a fuel cell as well as other rural and rural vehicles.

The switching connection mechanism 4 for selectively interlocking the power of the engine 3 with the vehicle driving mechanism 1 or the generator mechanism 2 means that when the single engine 3 is requested to operate the vehicle Means a configuration in which the power is switched and connected to the generator mechanism when generation of generation power is requested toward the vehicle drive mechanism (1).

In this case, the concept of the present invention uses the term switching in the sense that the electric power production and the vehicle driving do not need to be performed at the same time, and the concept of the present invention is selectively connected to any one of them (refer to FIG. 4 and FIG. 5). That is, the engine 3, which is a single structure, is selectively and selectively interlocked with the vehicle driving mechanism 1 or the generator mechanism 2 by the selective interlocking action of the switching connection mechanism 4, Quot; can be composed of an electric or electronic clutch which is controlled to be operated by a magnet switch. In other words, when the electric switch is turned on from the outside, the magnet switch is activated by the electromagnetism operation, so that the clutch is electronically operated to temporarily connect the engine power to the generator mechanism. In this case, the power of the engine 3 can be controlled to be supplied or not to the generator mechanism by keeping the gear for vehicle operation in the neutral state. Whether or not the power is supplied by the operation of the vehicle is determined by the operation of the gear lever of the user do. With such a configuration, a plurality of power conversion transmission and transmission can be performed as a single engine. (That is, "the connection of the generator is connected by an electronic clutch and the drive-side connection of the vehicle is interrupted by the operation of a manual gear").

As another embodiment, the switching connection mechanism 4 may adopt a configuration for controlling the connection with the generator by a mechanical gear (box). This configuration would be easy to understand if the vehicle's gear is reminiscent of two-stage operation. It is preferable that the vehicle is mechanically combined such that the gear box is operated in a neutral state (not connected to a generator mechanism).

On the other hand, in the structure in which the magnet switch is operated according to the switch operation, if the user operates the generator while operating the switch with the operation of the generator, the engine 3 of the vehicle may be overloaded. In particular, when the generator is connected and the engine is running, the engine speed corresponding to a certain AC frequency (for example, 60 Hz or 50 Hz) (3600 rpm for a gasoline engine, 1800rpm, etc.), it is preferable to keep the vehicle at such a time.

Therefore, as shown in FIG. 5, the switching connection mechanism 4 of the present invention is a function of a moving sensor that senses the movement of the vehicle, such that the sensor module 9 controls the generator output to be shut off during vehicle operation, (Current or voltage) sensor that senses the vehicle's operation.

In the case of the power sensor, it may be possible to transmit the power from the no-current output over a certain period of time to the driving side of the vehicle. In addition, by sensing whether the power supply state is detected by reversing or inserting the wire cord, It is possible to interlock the driving operation and the alarm so that the vehicle driving mechanism can not be interlocked with the engine. That is, the switching connection mechanism may mechanically detect whether or not the electric wire cord is inserted and control the electric power to be transmitted to the driving side of the vehicle.

The generator mechanism of the embodiment may include an electronic or mechanical governor 8 that senses the degree to which the output power of the generator 2 is supplied at the load stages 5, 6, 7 and automatically stabilizes the engine output. With this configuration, the generated voltage can be stably maintained despite the electrical load variation. That is, if the load is heavy, the action of the governor 8, which operates lightly, is achieved if the mechanical actuator is deeper and the load is light. The governor may be a mechanical governor using the vacuum pressure of the engine inlet or a cruise control of an electronic control system (ECU).

The generator mechanism associated with this configuration may include a configuration that automatically decelerates the generator governor when it is desired to move the vehicle by detecting movement of the vehicle.

Further, in the generator mechanism, the engine is rotated at 3600 rpm or 1800 rpm (the detailed rpm can be determined by the desired amount of power or the power supply frequency), or the power supply is stabilized in the range of 45 Hz to 65 Hz, And outputting the control signal. In the present invention, this value is referred to as a set number of revolutions or a set frequency. The specific set value is determined according to the characteristics of a (gasoline or diesel) engine, a generator, and a reduction gear matching these. According to this configuration, an appropriate electric power can be stably supplied to an electric device such as a power tool.

Furthermore, it is preferable that a filter for shaping a waveform such as a voltage fluctuation and a surge generated in the rotation of the engine is inserted into the generator mechanism system (2, 5, 6, 7). This configuration minimizes the problem of surge when the power switch is turned on in a stable state at the above-mentioned set frequency but the power consumption of the power source is large, and when the hunting occurs like a gentle wave in the rotation of the engine, Filtering).

Further, when the residual amount of the fuel during use of the generator becomes equal to or lower than a set level, for example, 3 liters or 5 liters, the generator mechanism 2 or the switching connection mechanism 4 may be controlled by an alarm, an alarm lamp or a hazard lamp, And the like. This function is to prevent the problem of running out of the fuel needed for the operation of the engine while focusing on the power generation of the generator. Therefore, in the present invention, a warning is sounded when the fuel is lowered to a set level or lower, and a warning time is arbitrarily set in the range of the remaining amount of fuel according to the user's environment, In hardware and software.

Furthermore, the function of this warning is to allow the user to know quickly in the remote place by using the amplifier or the network, for example by using the mobile phone's app, and to take countermeasures such as remote control on / It is preferable that the application for the mobile communication terminal is interlocked so that the operation such as changing / setting of the setting level of the mobile communication terminal can be taken remotely.

As shown in FIG. 5, the generator mechanism of the present invention can directly connect a direct current or alternating current from the generator 2 to the receptacle 2a, but since a general power tool uses alternating current (for example, 220 volts) It is also possible to output the direct current directly. At this time, the stabilization of the AC voltage is performed by the governor 8 directly connected (not shown) from the generator 2 or by a mechanical governor which operates (not shown) by detecting the vacuum suction state. However, even in this case, direct output from the generator 2 may cause some surge or noise in the AC waveform.

In view of this, it is possible to concentrate the use of the inverter 6 and to supplement the battery when outputting alternating current. The configuration of Fig. 5 is just an example of such a configuration.

5, a relatively small battery 5 serving as a filter is connected to the output of the generator 2, and an inverter 6 is connected to the output of the generator 2, 2 to the inverter 6 and to produce the power 7 at the output of the inverter 6 by filtering the unstable output of the battery 5 once in the battery 5 as an embodiment. Since the output of this inverter is interlocked with the governor 8, the operation of the governor 8 at this time can be further refined. Further, if the output of the inverter is drawn out to the waterproof cover type receptacle 2a mounted on the outside of the vehicle, it becomes convenient because the outlet can be used when the user wants to use electric power. (The generator 2 at this time is an alternator including a rectifier or a DC generator).

Particularly, this configuration is an idea that the battery 5 operates as a filter, so that the output of the generator 2 is produced by the alternating current of the stabilized voltage and the waveform from the generator through the general coupling of the battery filter, . However, the concept of connection between the battery and the inverter of the present invention is not limited to this, and the battery may be interlocked with a large-capacity battery so as to be a main power source.

In the configuration of the present invention, the generator mechanism 2 is preferably installed in the bonnet in the concept of an alternator, so as to be protected from theft or the like. At this time, when the installation place in the bonnet is not easy, the switching connection mechanism 4 of the present invention can connect the generator mechanism 2 and the engine 3 via the flexible joint. Here, the flexible coupling is a kind of universal joint that transmits rotational force even if the joint axis is not correct, that is, a structure like a flexible joint. According to the structure of the present invention, it is possible to prevent generation of disruption in the production of electric power even if the engine shaft and generator construction are inconsistent with each other due to the accumulation of running in a poor environment.

Meanwhile, the present invention can be configured to be interlocked with engine power and pulleys in the bonnet. An example of this is shown in FIG. 6B.

That is, FIG. 6A is a diagram showing a state in which the conventional engine 3 and the alternator 3a (hereinafter referred to as a first generator) transmit rotary power through pulleys, respectively. It will be seen here that the first generator pulley 3a and the engine pulley 3f are coupled in a power transmission relationship by the belt 3d. In Fig. 6A, 3b and 3c are auxiliary pulleys for maintaining a path or tension.

On the other hand, FIG. 6B is a view showing a hardware coupling concept of the power transmission system in which the generator mechanism 2 (hereinafter referred to as the second generator) of the present invention is interlocked with the engine. In FIG. 6B, a separate second belt 3e is formed for the second generator. However, this embodiment is a concept that the structure is preferable for mechanical stability or maintenance. In FIG. 6B (2 and 4) is an external view showing the pulley of the generator, but the switching connection mechanism described below is included in the software.

In this regard, FIG. 7 is a diagram showing how the hardware combination works in software.

That is, through the configuration of FIG. 6B, it can be confirmed that the switching connection mechanism 4 and the second generator 2 are connected to the engine pulley 3f. In FIG. 7, Sensing the amount of power used to increase or decrease the power, or to control the engine with the basic engine operating conditions, while operating the linkage system between the engine and the generator mechanism. (The switching connection mechanism 4 is hidden behind the generator mechanism 2 and the generator mechanism 2 schematically shows the generator and the pulley together) and the engine pulley 3f is connected to the crankshaft and the pulley As shown in the diagram.)

More specifically, when the user manipulates the operating switch of the second generator 2 with the intention of using the second generator, the switching connection mechanism 4, which is the second generator clutch in Figure 6b, operates, 7, the second generator switch 102 and the second generator switch ON state detection 103 are depicted.

That is, according to the interlocking procedure of the switch operation, the engine is operated with the torque necessary for operating the second generator in FIG. 7 (104 in FIG. 7) (104). If it is not used or the amount of power usage is less than the set power usage (106), the clutch of the second generator is turned off or returned to the basic engine operating condition, which is the normal idling (107).

The configuration for sensing the use of electric power can be detected through a configuration that senses a current flowing to a final output terminal of the generator or detects a voltage of the battery itself. Through this feedback control, the hardware external structure in FIG. , Which is defined as a software configuration in the present invention.

In the present invention, whether to use or not is determined by whether or not it is equal to or greater than the set power. Here, the set power refers to a value that is set arbitrarily among a range in which a current is supplied to at least the lower end, It says. For example, in the case of the lower stage, it may be said that the 3KW generator is using 0.1W or less, and it may be judged that the battery voltage is under 12.6V. (It should be understood, however, that when comparing each of the comparison steps in FIGS. 7 to 8 with voltages, yes and no are interlocked with each other.

In the software interlocking configuration, when the power demand through the second generator is higher than the set power, it is operated at a maximum of 3600 rpm for a gasoline engine and 1800 rpm for a diesel engine. When the power demand is lower than a set power, It is preferable to set the ECU so that the governor automatically operates at an appropriate value therebetween through feedback control. That is, it is most preferable that the power of the engine is automatically controlled according to the power requirement. However, the present invention is not limited to such an automatic operation as long as the engine is operated so that the inverter can produce stable electric power as long as the battery is placed as a buffer element in the present invention.

Briefly, Figures 6B and 7 show,

As a hardware mechanism, " the generator mechanism is a second generator for generating electric power, a hardware connection which is connected to a pulley of an engine crankshaft together with a first generator for a vehicle operation so as to be able to receive power, "

The hardware connection point is executed as the power transmission to the second generator only in the operational state of the second generator, and in the power transmission state, the power of the engine corresponding to the power output of the second generator Controlled configuration ".

Although not shown, the generator mechanism includes a first generator for vehicle operation and a vehicle air-conditioner as a second generator for generating electric power, and is connected to a pulley of an engine crankshaft to form a hardware connection capable of receiving power, And the power transmission to the second generator is interrupted when the power of the engine is transmitted.

This configuration corresponds to a software configuration in which the first generator, the second generator, and the air conditioner share one engine, in particular, the air conditioner and the second generator are operated simultaneously to prevent the load on the engine from being burdened.

8 shows a specific configuration. This configuration further connects the aerial configuration from steps (103) to (107) to steps (202) to (206) in FIG. 7, (102) are interlocked with each other so that the second generator and the air conditioner are harmonized with each other. Even in this configuration, the load of the engine is thoroughly prevented, but the specific operation and effect will be fully understood from the foregoing description, so that the explanation will be omitted.
