Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a display device for displaying the trim angle of a marine propulsion device such as an outboard motor or an inboard/outboard motor, that is, the vertical rotation angle of the marine propulsion device with respect to the hull. It is.

[Conventional technology]

In order to run a boat propelled by an outboard motor or the like in the best possible condition, it is necessary to optimally adjust the trim angle of the outboard motor or the like depending on the running condition. Therefore, this type of ship is provided with a trim angle adjustment mechanism and a trim angle display device that displays the adjustment result by the adjustment mechanism.

[Problem that the invention seeks to solve]

However, the conventional trim angle display device is simply an angle display device, and even when the trim angle falls within the chill HJt range, the trim angle display device merely displays the angle. Here, the tilt range refers to a large trim angle that is greater than or equal to a predetermined angle α; for example, the trim angle when the propeller of the outboard engine is completely lifted out of the water during berth is in the tilt range.

In this way, because conventional trim angle display devices are simply angle display devices, even if the trim angle falls into the tilt area during cruising, the pilot often fails to recognize this fact. . When sailing with the trim angle in the tilt range, the propeller of the outboard motor is exposed above the water surface and rotates in the air, reducing the load on the engine and causing it to overspeed. If this condition continues, in the worst case scenario, the outboard motor or other engine may seize up.

Means for Solving the °C Problem] The trim angle display device of the present invention has been made in view of the above problems, and detects the trim angle of a marine propulsion device and outputs a trim angle signal according to the detection result. It is determined whether the trim angle is in the tilt HJ range based on the trim angle sensor and the trim angle signal, and if the trim angle is not in the tilt range, only the display point corresponding to the trim angle is lit;
Is the trim angle chilled? and a display section that lights up all of the display points if the vehicle is in the J region.

[Effect]

If the trim angle is in the trim area (non-tilt area), only the display point corresponding to the trim angle lights up, and if the trim angle enters the tilt area, all the trim angle display points light up to display a warning.

〔Example〕 Hereinafter, the present invention will be described in detail along with examples.

FIG. 1 is a block diagram showing one embodiment of the present invention, and FIG. 2 is a perspective view showing the external appearance of a boat to which this embodiment is applied and is equipped with an outboard motor.

The trim angle display device of this embodiment can be roughly divided into a detecting section 7 and a display section 8, and the detecting section 7 is constituted by the existing trim angle sensor 1. The trim angle sensor l is the outboard motor 11
It is installed on the zero machine 12 or the hull attachment part 13,
The trim angle detected through mechanical means is converted into a voltage value.

Such a trim angle sensor is disclosed in, for example, Japanese Patent Application Laid-Open No. 55-85
No. 203, etc.

The display section 8 is composed of a control unit 2 and a liquid crystal display means 6. The control unit 6 can be functionally divided into an A/D conversion means 3, a trim angle determination means 4, and a display control means 5. A/D conversion means 3
Since the voltage value output from the trim angle sensor 1 is simply converted into a digital value, the output value directly indicates the trim angle. The trim angle determining means 4 is
A digital trim angle signal from the A/D conversion means 3 is input, and first, the trim angle indicated by this digital trim angle signal is
It is determined whether the angle is greater than or equal to a predetermined angle α.

At this time, if the trim angle is greater than or equal to the angle α, that is, if it is in the tilt region, a warning signal is output.

On the other hand, if the trim angle is less than or equal to the predetermined angle α, that is, if it is in the trim region, a level signal whose content is the level value is output in association with one of the 13 predetermined levels. The display control means 5 includes the bird wide-angle discrimination means 4
This is means for driving and controlling the liquid crystal display means 6 based on signals from the LCD.

As shown in FIG. 3, the liquid crystal display means 6 is incorporated into a marine meter 30 that includes various display sections including an engine speed display section 31, and is divided into 13 stages in the vertical direction. . And, on the right side of the liquid crystal display means 6, 1
Numbers up to 5 are printed and displayed at almost equal intervals,
Levels 1.4, 7.10.13 for numbers 1-5 respectively
is compatible.

Next, the operation of this embodiment will be explained. The trim angle can be adjusted using, for example, the driving force of a hydraulic cylinder. Switching the trim angle adjustment switch 14 to the up side increases the trim angle, and switching it to the down side increases the trim angle. can be operated to decrease.

The trim angle adjusted in this way is determined by the trim angle sensor 1.
is detected and inputted to the bird wide-angle discriminating means 4 via the A/D converting means 3. Now, if the trim angle is approximately at an intermediate angle and the wide-angle determining means 4 determines that the trim angle is level 7 out of 13 levels, the level signal is manually input to the display control means 5. In response to the input of this level signal, the display control means 5 lights up only the display point corresponding to level 7 (numerical display 3) of the liquid crystal display means 6.

FIG. 3 shows the display state at this time, and it can be seen that the bar-shaped display point located at the position of the printed number 3, that is, the display point of level 7 is lit (changed in color to black).

If the bird wide angle increases from this state, the bar display at the number 3 position (level 7) disappears, and any bar display from levels 8 to 13 is displayed. Conversely, if the trim angle decreases, one of the bars from levels 1 to 6 is displayed. That is, in either case, the level is displayed as a point by a single bar.

On the other hand, if the trim angle exceeds the predetermined angle α and enters the tilt region, the trim angle determining means 4 determines this and outputs a warning signal. The display control means 5 receives the warning signal and turns on all display points of the liquid crystal display means 6. Fourth
The figure shows the display state at this time. Displaying a plurality of bars in this manner does not occur when the trim angle is normal and is less than or equal to the predetermined angle α, that is, when the trim angle is within the trim region. Therefore, such a display is very conspicuous, and the operator can intuitively know that the trim angle has entered the tilt region. Therefore, it can be said that this all-on display is extremely excellent as a warning display.

Moreover, since the angle display of the trim angle and the warning display warning that the trim angle has entered the tilt area are displayed in the same display area, ``you only need to pay attention to this display area regarding the trim angle.'' It can give the operator a sense of security, and it is possible to provide a sense of security to the operator. This increases the 4'fF reality.

It goes without saying that the control unit 2 of this embodiment can be constructed from a single microcomputer. FIG. 5 is a flowchart showing the operational flow in such a case. After detecting the trim angle (step 101)
If the trim angle θ is greater than or equal to the predetermined angle α, all bar displays are turned on (steps 102 and 104);) If the rim angle θ is smaller than the predetermined angle α, a corresponding level bar display is performed.

Further, in this embodiment, the bird wide angle is displayed in 13 levels, but the number of levels is not limited to this.

〔Effect of the invention〕

As explained above, according to the trim angle display device of the marine propulsion device of the present invention, the bird wide angle is in the trim region (non-tilt region).
, only the display point corresponding to the trim angle lights up, and when the trim angle enters the tilt area, all the trim angle display points light up.

Therefore, if the operator pays attention to one display area, he or she can visually confirm the angle display of the trim angle and the warning display when the trim angle enters the chill BiM range. Moreover,
When displaying an angle, only one point within the display area is always lit, but when displaying a warning, all points are lit in contrast to when displaying the angle, making it very noticeable and providing a high warning capability.
