Abstract

PURPOSE:To enable the simple changeover of two power trim and tilt (PTT) devices into individual operation and simultaneous operation by connecting a mode changeover switch. CONSTITUTION:In the case of individually operating a PTT device corresponding to the outboard engine side, an operator first puts a mode changeover switch 17 in the 'off' state. In the case of increasing the inclination angle of the outboard engine, the knob of a PTT switch 22 disposed at a grip is operated on onto the 'up' side. Then a movable contact 25b moves onto the contact a-a' side so as to become nonconductive between the contacts b-b' and conductive between the contacts a-a'. When the contacts a-a' of a PTT relay 25 become conductive, a current flows through the path of a battery 24 the terminal (a) of the PTT relay 25 the terminal (a') of the PTT relay 25 a PTT motor 27 the terminal (d') of a PTT relay 26 the terminal (d) of the PTT relay 26 earth. The PTT motor 27 is thereby operated onto the 'up' side, so that the PTT device on the outboard engine side is operated onto the 'up' side.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power trim and tilt mechanism control device mounted on a small boat, and more particularly to a power trim and tilt mechanism control device.
The present invention relates to a power trim and tilt mechanism control device suitable for easily switching between single operation and simultaneous operation of a power trim and tilt mechanism of a machine.

[0002]

2. Description of the Related Art Conventionally, as a tilt angle control device for an outboard motor, for example, one disclosed in Japanese Utility Model Laid-Open No. 3-297 has been proposed. The technology described in the publication is for each PTT of two outboard motors.
(Power trim and tilt) It is possible to switch between the operation of operating each device independently and the operation of operating each PTT device at the same time. An up relay is provided between the up control lines of the outboard motor. , A down relay is provided between the down control lines, and a changeover switch for controlling each of these relays is provided.

In the technique disclosed in the above publication, when the changeover switch is in the off state, the PTT device corresponding to the PTT device to be operated among the PTT devices is turned on, and the PTT device is operated independently. be able to. Further, when the changeover switch is turned on, the two relays become conductive. Therefore, even if any of the PTT switches corresponding to each PTT device is turned on, each PTT device is turned on. Can be activated simultaneously.

On the other hand, as shown in FIG. 5, for example, one PTT switch 3 is provided on the tip side of the grip 2 attached to the control lever 1, and the control box 4 is provided.
Two PTT switches 6 and 7 are arranged on the cover part 5 of
When operating each PTT device of two outboard motors individually, of the two PTT switches on the control box side, turn on the PTT switch on the PTT device side to be operated, while operating each PTT device. In some cases, the PTT switch at the tip of the control lever is turned on when operating both at the same time. In this case, each PTT
The circuit is constructed by incorporating two relays, one for the up side and one for the down side, in the circuit of the PTT switch that activates the device simultaneously.

[0005]

However, in the former one (the technique described in the publication) of the above-mentioned conventional techniques, two PTT devices are operated independently and two
Since switching between the case where the machines are operated at the same time is performed by using one changeover switch and two relays, there are drawbacks that the structure such as a circuit configuration becomes complicated and the cost becomes high.
When operating two PTT devices at the same time, the up-side relay and down-side relay operate simultaneously,
There is also a problem that one side of the relay will perform unnecessary operation (the down side relay is unnecessary for up side operation, the up side relay is unnecessary for down side operation), and it consumes unnecessary power. .

On the other hand, in the latter of the above-mentioned conventional techniques, one PTT is provided at the tip of the control lever.
Since the switch is arranged and two PTT switches are arranged on the control box side, when operating two PTT devices at the same time, the PTT switch at the tip of the control lever may be turned on. There is no problem, but if you want to operate each of the two PTT devices individually, the PTT switch is installed on the control box side. There is a case where the driver has to operate with the hand released from the control lever until the angle becomes as desired by the driver, which is complicated. Also, in the circuit of the PTT switch that operates two PTT devices at the same time,
Since it is necessary to provide two relays, one for each of the up side and the down side, the structure becomes complicated and the cost becomes high.

The PTT relay 25 is of a two-point contact type, and the movable contact 25b is normally pressed to the contact bb 'side by the urging force of a spring. However, when the exciting coil 25a is energized, it is excited. Since a magnetic force is generated in the coil 25a, the shaft 25 connected to the movable contact 25b

The PTT motor 31 and the like configure a PTT circuit corresponding to the PTT device on the outboard motor 13 side.

Next, the operation of the PTT device in the power trim and tilt mechanism control device of the present embodiment constructed as described above will be explained.

(1) When the PTT devices of the two outboard motors 12 and 13 are individually operated.

For example, when independently operating the PTT device corresponding to the outboard motor 12, the driver first sets the mode changeover switch 17 to the off state (independent operation side). Outboard motor 1
To increase the inclination angle of 2, the knob of the PTT switch 22 provided on the grip 20 is turned on to the up side.

With the ON operation of the PTT switch 22 to the up side, the current changes from the battery 24 to the up side contact of the PTT switch 22 to the exciting coil 25a of the PTT relay 25.
Since the shaft 25c of the movable contact 25b, which has been pressed to the contact bb 'side, is attracted to the exciting coil 25a because it flows through the ground path, the movable contact 25b moves to the contact aa' side, The contact points b-b 'are non-conductive, and the contact points a-a' are conductive.

When the contact points aa 'of the PTT relay 25 become conductive, the current is changed from the battery 24 to the PTT relay 25.
A terminal → PTT relay 25 a ′ terminal → PTT motor 27 → PTT relay 26 d ′ terminal → PTT relay 26
Flow from the d terminal to the ground. This allows PTT
Since the motor 27 operates in the up direction, the PTT device on the outboard motor 12 side operates in the up direction.

Contrary to the above, when the tilt angle of the outboard motor 12 is to be lowered, the PTT mounted on the grip 20 is used.
The knob of the switch 22 is turned on to the down side. PT
As the T switch 22 is turned on to the down side, the current is changed from the battery 24 to the down side contact of the PTT switch 22 to P.
Since the exciting coil 26a of the TT relay 26 flows through the path of ground → the shaft 26c of the movable contact 26b, which has been pressed to the contact dd 'side until then, is excited by the exciting coil 26a.
As a result, the movable contact 26b moves to the contact c-c 'side, and the contact d-d' is non-conducting and the contact c-c 'is conducting.

When the contacts cc 'of the PTT relay 26 become conductive, the current is changed from the battery 24 to the PTT relay 25.
A terminal → PTT relay 26 c terminal → PTT relay 2
6'c terminal-> PTT motor 27-> PTT relay 25 b'terminal-> PTT relay 25 b terminal-> ground path. As a result, the PTT motor 27 operates in the down direction, so that the PTT device of the outboard motor 12 operates in the down side.

After that, when the operation of the PTT device of the outboard motor 12 is stopped, the PTT relay 25 is excited by returning the contact of the PTT switch 22 to the neutral position in both the above-described up operation and down operation. Coil 25a, PTT
Since the circuit of the exciting coil 26a of the relay 26 is cut off, the exciting force of the exciting coil 25a of the PTT relay 25 and the exciting coil 26a of the PTT relay 26 disappears.
The movable contact 25b of the TT relay 25 and the movable contact 26b of the PTT relay 26 return to their original positions. This allows
Since the circuit of the PTT motor 27 is cut off, the operation of the PTT motor 27 is stopped and the operation of the PTT device of the outboard motor 12 is stopped.

On the other hand, the operation of the PTT device on the outboard motor 13 side alone is also the same as the case of the PTT device on the outboard motor 12 side described above, and a description thereof will be omitted.

(2) When operating the PTT devices of the two outboard motors 12 and 13 simultaneously.

Each PT corresponding to the two outboard motors 12 and 13
When operating the T devices at the same time, the driver first turns on the mode changeover switch 17 (simultaneous operation side). Along with this, the contacts i-i 'and contacts j-j' of the mode changeover switch 17 are turned on. P corresponding to the outboard motor 13
When the knob of the TT switch 23 is turned on to the up side,
A current flows through the path of the battery 28 → the contact on the up side of the PTT switch 23 → the exciting coil 29a of the PTT relay 29 → the ground, and the contact i− of the mode changeover switch 17
i → Exciting coil 25a of PTT relay 25 → flows through the path of ground.

Since the current flows through the path, the exciting coil 29a of the PTT relay 29 is energized, and the shaft 29c of the movable contact 29b which has been pressed to the contact ff 'side until then is attracted to the exciting coil 29a. result,
The movable contact 29b moves to the contact ee 'side, and the contact f-
There is a non-conduction state between f ′ and a conduction state between the contact points ee and e ′. Similarly, the exciting coil 25a of the PTT relay 25 is energized, and the shaft 25c of the movable contact 25b which has been pressed to the contact bb 'side until then is excited by the exciting coil 2a.
As a result of being attracted to 5a, the movable contact 25b contacts the contact aa '.
Side, contact bb 'is non-conductive, contact a-
Conduction is established between a '.

By the operation of the PTT relays 29 and 25, the current is changed from the battery 28 to the contact ee 'of the PTT relay 29.
PTT motor 31 → contact point hh 'of PTT relay 30 →
While flowing through the earth path, the battery 24 → contact point aa ′ of the PTT relay 25 → motor 27 → PTT relay 2
6 through the contact point d-d '→ ground. As a result, the PTT motor 27 and the PTT motor 31 operate simultaneously, so that the PTT devices of the two outboard motors 12 and 13 simultaneously operate in the up side.

Contrary to the above, the PT corresponding to the outboard motor 12
Even when the knob of the T switch 22 is turned on to the up side, the same control as in the case of the PTT switch 23 described above is performed, so that each P of the two outboard motors 12 and 13 is controlled.
The TT device can be operated in the up side at the same time.

On the other hand, when the knob of the PTT switch 22 is turned on to the down side, the current flows through the path of the battery 24 → the contact of the down side of the PTT switch 22 → the exciting coil 26a of the PTT relay 26 → the earth and the mode changeover switch 17 Contact j-j '→ excitation coil 30a of the PTT relay 30 → ground.

Since the current flows through the path, the exciting coil 26a of the PTT relay 26 is energized, and the shaft 26c of the movable contact 26b, which has been pressed to the contact dd 'side, is attracted to the exciting coil 26a. result,
The movable contact 26b moves to the contact cc 'side, and the contact d-
A non-conduction state is established between d'and a conduction state is formed between contacts cc '. Similarly, the exciting coil 30a of the PTT relay 30 is energized, and the shaft 30c of the movable contact 30b, which has been pressed to the contact hh 'side until then, is excited by the exciting coil 3.
As a result of being attracted to 0a, the movable contact 30b contacts the contact gg '.
To the side, contact points h-h 'are non-conductive, contact point g-
Conduction is established between g '.

Due to the operation of the PTT relays 26 and 30, the current is changed from the battery 24 to the contact point cc 'of the PTT relay 26.
PTT motor 27 → PTT relay 25 contact bb '→
While flowing through the earth path, the battery 28 → contact point gg ′ of the PTT relay 30 → motor 31 → PTT relay 2
9 through the contact point ff '→ ground. As a result, the PTT motor 27 and the PTT motor 31 are simultaneously operated, so that the PTT devices of the two outboard motors 12 and 13 are simultaneously operated to the down side.

As described above, according to the present embodiment, when operating each PTT device corresponding to the two outboard motors 12 and 13 individually or when operating each PTT device simultaneously, This can be easily performed by only one-touch operation (on / off operation) of the mode changeover switch 17.

When the PTT devices corresponding to the two outboard motors 12 and 13 are simultaneously operated, the PTT switch 2 disposed on each of the two grips 20 and 21.
Since any of the PTT switches 2 and 23 may be operated, the operability is extremely good for the driver, and there is an advantage that it is less affected by the mounting conditions of the remote control box 14.

Further, even when each PTT device corresponding to the two outboard motors 12 and 13 is individually operated, or each PTT device is operated.
Even if the TT devices are operated at the same time, the same PTT switch can be used, and therefore the driver can operate the device without feeling any discomfort.

Further, when the PTT devices corresponding to the two outboard motors 12 and 13 are switched from the independent operation to the simultaneous operation, the one-touch operation of the mode changeover switch 17 can be performed. It is no longer necessary to release your hand from the control lever grip for a while.
