Description

{ENGINE STARTER FOR SEA BOAT}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a marine engine starter, and more particularly to an engine starter of a marine boat used for starting an engine of a marine boat.

Unless otherwise indicated herein, the contents set forth in this section are not prior art to the claims of this application and are not to be construed as prior art to be included in this section.

Generally, when the battery is discharged, the start motor can not be started and the engine can not be started. Therefore, when the battery is discharged, the engine must be started by driving the start motor by being temporarily supplied with power from the outside. Such an engine starter is called a jump starter.

1 is a perspective view showing a conventional jump starter for a vehicle. To start the engine using these jump starters, first connect the cable clamps to the + and - poles of the vehicle battery, respectively. And if you activate the jump starter, you can start the engine.

On the other hand, among the marine boats, small fishing fishing boats (less than 3 tons) equipped with outboard engines start the engine using DC 12V battery, and the fishing boats (more than 5ton) use the DC 24V battery to start the engine.

The conventional vehicle jump starter can only start the engine only in the vehicle, and the battery capacity is too small to start the engine of the marine boat. In addition, depending on the type of the battery used for the marine boat, the DC 12V or DC 24V battery must be separately provided, which is inconvenient.

Therefore, the definition should be based on the contents throughout this specification. Like numbers refer to like elements throughout.

Figures 2 to 8 illustrate one embodiment. 3 is a circuit diagram, Fig. 4 is a circuit diagram, Fig. 5 is a perspective view, Fig. 6 is a perspective view and Fig. 6 is a perspective view of an operating portion 170 of the marine engine starter 100. Fig. 7 is a perspective view of the cable tongue 144 of the marine engine starter 100, and Fig. 8 is a perspective view of the marine engine starter 100. Fig.

The disclosed marine engine starter 100 is installed directly on a marine boat. Here, the marine boats include all boats, ships, fishing boats, etc. used in the sea. The disclosed marine engine starter 100 can be used to start the engine when the engine can not be started due to the discharge of the battery B of the marine boat.

2 to 5, the marine engine starter 100 according to the disclosed embodiment includes a charging unit 110, a case 120, a lead-in unit 130, a cable 140, a series-parallel switching unit 150, A control unit 160, an operation unit 170, a tester 180, and a protection circuit (not shown).

Referring to FIGS. 2 and 3, the charger 110 includes two charging cells 112 and 112 '. Each of the charging cells 112 and 112 'is provided in a general battery system, and is rechargeable and supplies DC power. The charging cells 112 and 112 'preferably supply a DC 12 V power supply, but are not limited thereto.

The inlet unit 130 draws the external power source P into the charging unit 110 and maintains the charging unit 110 in a fully charged state. The charging unit 110 is connected to an external power source P such as a generator (not shown) or a solar cell module (not shown) of a marine boat equipped with a marine engine starter 100 to charge the power source. Therefore, the charging unit 110 is maintained in a condition capable of starting the engine of the marine boat at any time.

Generally, the generator of the ship corresponds to an alternator, and the input unit 130 receives an AC power and converts the AC power to a DC power and supplies the AC power to the charger 110. When the charging unit 110 is maintained in the fully charged state, the protection circuit prevents the charging unit 110 from becoming overcharged. Such a protection circuit may comprise, for example, a protection IC.

Meanwhile, the charger 110 is connected to the battery B of the marine boat through the cable 140 to start the engine of the marine boat. The cable 140 is connected to the (+) terminal P + and the (-) terminal P-, respectively, and the cable clamp 144 is formed at the end of the cable 140. The positive terminal cable 142 is connected to the positive terminal of the battery B of the marine boat to start the engine by using the cable tongs 144 and the negative terminal cable 142 ' Connect to pole. The length of the cable 140 is preferably 20M to 30M, but may be variously formed depending on the size of the marine boat on which the marine engine starter 100 is installed.

Preferably, the cable 140 is provided with a cord drill (not shown). The cord drill assists the user in twisting the cable 140 when carrying the cable 140.

The serial-parallel switching unit 150 selectively connects the charging cells 112 and 112 'of the charging unit 110 in series or in parallel, thereby adjusting the output voltage level of the charging unit 110. The serial-parallel switching unit 150 performs a switching operation in response to a switching signal generated by the control unit 160, which can be manually switched by a user. For example, when the charging unit 110 is composed of two DC 12V 150Ah charging cells 112 and 112 ', when the charging cells 112 and 112' are connected in parallel, a DC 12V 300Ah power is supplied, When connected, supply DC 24V 150Ah power. As an example of the series-parallel switching unit 150, a semiconductor switch including a rotary switch or a transistor may be used, but is not limited thereto. Meanwhile, when it is necessary to provide the output voltage of the charger 110 at a constant level of the constant voltage, a voltage converter (not shown) may be provided.

Referring to FIG. 4, a circuit diagram of a serial-parallel switching unit 150 having a plurality of switches is shown. If the charge cells 112 and 112 'are to be connected in series, the series switches S12 and S0 are closed among the plurality of switches S0, S1, S2 and S12, Is opened. The serial switch S12 is opened among the plurality of switches S0, S1, S2 and S12 and the parallel switches S1 and S2 and the switches S ) Is closed.

Referring to FIGS. 2, 3 and 5, the controller 160 controls the on / off state of the charger 100. 2 and 3, the control unit 160 controls the serial-parallel switching unit 150 to select the serial or parallel connection mode of the charging cells 112 and 112 ' . The control unit 160 receives the control signal of the operation unit 170 to be described later and controls the switching operation of the charging unit 110 and the serial-parallel switching unit 150 according to the control signal. The control unit 160 may be provided as a control circuit on a circuit board on which the charging unit 110 is implemented.

As shown in FIG. 5, the case 120 accommodates the charging unit 110 therein. Also, the case 120 is formed to have a watertight property, thereby protecting the charging unit 110 from the humidity and salinity of the ocean to prevent corrosion of the charging cells 112 and 112 '. The case 120 is preferably formed of a material having good thermal conductivity to dissipate the heat radiated from the charger 110.

On the other hand, it is necessary to check the state of the battery B of the marine boat since the marine engine starter 100 can start the engine of the marine boat only when the battery B of the marine boat is discharged . The tester 180 measures the internal resistance value and the voltage of the battery B of the marine boat when the cable 140 is connected to the battery B of the marine boat. Accordingly, the user can confirm the normal, discharge, or poor state of the battery B of the marine boat by measuring the internal resistance value of the tester 180 and the voltage. The tester 180 may be a commonly used load meter or a voltage meter and may be provided in the cable 140 or the cable clamp 144, although not shown in the drawings. Or the tester 180 may be preferably provided inside the case 120.

The following is a chart roughly showing the SOC (State Of Charge) of the battery in an open circuit state.

Charge amount 12V battery 24V battery 100% 12.73 25.46 90% 12.62 24.24 80% 12.50 25.00 70% 12.37 24.74 60% 12.24 24.48 50% 12.10 24.20 40% 11.96 23.92 30% 11.81 23.62 20% 11.66 23.62 10% 11.51 23.02

The voltage of the battery B of the marine boat can be measured through the tester 180 and the approximate charge amount and the discharge can be confirmed. If the battery B is less than 11.51V when the battery B is 12V and less than 23.02V when the battery B is 24V, the amount of the battery is less than 10% and the battery B is finally discharged. Also, the tester 180 can measure not only the voltage but also the internal resistance of the battery B to measure the state of the battery B in more detail. The appropriate internal resistance value of the battery B can be set by a person skilled in the art according to the available voltage of the battery.

2 and 5, the operation unit 170 corresponds to a configuration capable of controlling the control unit 160, and the control unit 160 is controlled upon receiving a control signal of the operation unit 170. FIG. As shown in FIG. 5, the operating unit 170 is provided while cutting a part of the cable 140 and connecting the cables 140 therebetween. However, the present invention is not limited thereto, and the operation unit 170 may be provided in the form of a wireless terminal.

In general, in the case of a marine engine starter 100 used in the sea, the marine engine starter 100 can not be moved with the marine engine starter 100 because of its large volume. Therefore, after the cable 140 is connected to the battery B of the marine boat, the user can operate the marine engine starter 100 without operating the marine engine starter 100, The marine engine starter 100 can be operated remotely.

6, the operation unit 170 includes a display unit 172, an alarm unit 174, a vibration unit 176, a first button 177, a second button 179, a status indicator 182, .

The display unit 172 displays at least one of an on / off state of the charging unit 110, an output voltage of the charging unit 110, a remaining charge amount of the charging unit 110, and a measurement result of the tester 180. The display unit 172 may be formed of LEDs, but is not limited thereto.

When the tester 180 is provided inside the case 120, the status indicator 182 indicates the state of the battery B of the marine boat in accordance with the result of the measurement by the tester 180. For example, when the state of the battery B is normal, green light or the like may be emitted from the status indicator 182, and when the battery B is in a discharge state, it may be in a yellow state. Therefore, the user can easily grasp the current state of the battery B of the marine boat without calculating the internal resistance and the voltage.

Meanwhile, the first button 177 and the second button 179 of the operation unit 170 are exposed to the outside. The first button 177 controls on / off of the charging unit 110 and the second button 179 selects the serial / parallel connection scheme of the serial-parallel switching unit 150. When power is supplied to the cable 140, when the cable tongs 144 contact each other, sparks may be splashed or shorted, and the cable 140 may be connected to the batteries B ). The user connects the battery B of the marine boat and the cable 140 in a state where the charger 110 is off and connects the battery B and the cable 140 via the operating unit 170 without returning to the place where the marine engine starter 100 is provided. It is possible to charge the battery B of the marine vessel safely and conveniently by turning on the charging unit 110 even at a long distance.

If the charging unit 110 is in the ON state in the state where the battery B is not measured by the tester 180 and the cable 140 is not connected to the battery B in the marine boat. At this time, the control unit 160 operates the alarm unit 174 or the vibration unit 176 included in the operation unit 170. The alarm unit 174 generates a buzzer sound and the vibration unit 176 generates vibration, so that the user senses that the charger unit 110 is on. Therefore, an accident such as a shot can be prevented in advance.

Referring to FIG. 7, the marine engine starter 100 further includes a light emitting element 145.

The light emitting device 145 may be provided on the cable 140 or may be provided on the cable tongue 144 as shown in FIG. Preferably, the light emitting device 145 is formed of an LED and has its own power source. Therefore, the light emitting device 145 can generate the light source even when the charging unit 110 is off, and there is no risk of short-circuiting or sparking due to the contact of the cable tongue 144.

8, the disclosed marine engine starter 100 further includes a connector 146. [

A connector 146 is provided at an end of the cable 140, and each cable 140 is connected to each other by a connector 146. The connector 146 is divided into a female connector 146-1 and a male connector 146-2 and is coupled to each other by the projecting portion 147 and the latching jaw 148. [ A plurality of protrusions 147 are formed on one side of the female connector 146-1 so as to protrude inward.
