Abstract

(57) [Summary] [Structure] A sound pattern storage circuit (3) in which a warning sound pattern is stored in advance, a horn switch (1) of a vehicle, a timer (2) for measuring the length of operation, and a horn switch. When the operation time of (1) is within the set time limit of the timer (2), the sound pattern output from the sound pattern storage circuit (3) is output to the horn, and the horn switch operation time is set at the time limit of the timer (2). When above, horn switch (1)
A sounding device for a vehicle, which is provided with a switching device (5) for outputting a sound form output according to the operation of 1. to a horn (4). [Effect] Even in the case of a quick or random short horn switch operation, the warning sound of a preset pattern calls attention and the danger of one-handed handle operation can be minimized. Also, when the horn operation can be safely performed, the sound can be produced with the conventional operation.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a vehicle horn that varies the length of the sound depending on the operating time of the horn switch.

[0002]

[Prior Art]

 In conventional automobile horns, the horn (electric horn) is activated by pressing the horn switch linked to the button in the center of the handle or the arc-shaped lever, and the length is the time when the horn switch is pressed. Was the same as

[0003]

[Problems to be solved by the device]

 However, with a conventional horn that only sounds the horn while the horn switch is being pressed, a long horn that is sufficient to alert the attention of other vehicles or pedestrians is issued. Even so, since I try to return both hands to the steering wheel quickly in order to concentrate my attention on the steering wheel operation, the operating time of the audible noise becomes short, or the hand trying to press the horn switch slips. It was inconvenient for safety because the horn switch could be pressed only momentarily, and as a result, it was not possible to obtain a warning sound of sufficient length as intended.

Therefore, the problem to be solved by the present invention is to eliminate the drawbacks in the case where the sounding operation is insufficient without losing the characteristics peculiar to the conventional horn.

[0005]

[Means for Solving the Problems]

 In order to solve this problem, a vehicle horn of the present invention comprises a ringing pattern storage circuit that stores a ringing pattern of a ringing horn in advance, a timer that measures the length of operation of a horn switch of the vehicle, and the horn. When the operation time of the switch is within the set time limit of the timer, the sound pattern output from the sound pattern storage circuit is output to the horn, and the horn switch operation is performed when the horn switch operation time is equal to or longer than the set time limit of the timer. It is characterized by including a switching device for outputting the same sound form output to the horn.

[0006]

[Action]

 When the horn switch operation is shorter than the set time limit of the timer, the timer identifies and the switching device activates the sound pattern storage circuit, and the horn sounds with the input sound pattern.

【Example】

 Hereinafter, the present invention will be described in detail with reference to embodiments. FIG. 1 is a circuit diagram showing an embodiment of a horn according to the present invention. In the figure, 1 is a horn switch, 2 is a timer, 3 is a tone pattern storage circuit, 4 is a horn, 5 is a switch, 6 is a battery, and 7 is a fuse. The operation of the circuit of this embodiment is shown in FIG. Fig. 2 (a) shows the case where the horn switch on-time is shorter than the timer setting time τ, and Fig. 2 (b) shows the case where it is longer than τ.

When the horn switch 1 is pressed shorter than the set time τ of the timer 2, the output is not output from the timer 2 because the set time τ of the timer 2 is shorter than the set time τ, for example, 0.5 seconds. The contact output of the signal causes the sound pattern memory circuit 3 to start via the normally closed contact of the switch 5, and the horn 4 sounds in the sound pattern.

On the other hand, when the horn switch 1 is pressed longer than the timer setting time period τ, the timer 2 operates after the setting time period τ to switch the contact of the switch 5, and the contact output of the horn switch 1 is changed to the horn. Since it is directly connected to the horn 4, the horn 4 sounds only while the horn switch 1 is pressed, and functions as a normal horn. If the ringing pattern preset in the ringing pattern storage circuit 3 is an intermittent sound, if the length of the first sound of the intermittent sound is set to be slightly longer than τ (0.5 seconds), The sound is connected without interruption when switching between.

In the above embodiment, the setting time period τ of the timer 2 is set to 0.5 second, but it can be set arbitrarily. Further, as the switch 5, an example of a relay is shown in FIG. 1, but an electronic switch may be used. Further, in the above embodiments, the example of the intermittent sound is shown as the sounding pattern, but a single long sound may be used. In this case, even if the horn switch 1 is pressed and immediately released, for example, a continuous sound of about 3 seconds is emitted. A one-shot multivibrator circuit can be used as the tone pattern storage circuit 3 at this time.

[Effect of the device]

 As described above, according to the present invention, even in the case of a quick or random short horn switch operation, the audible alarm of a preset pattern calls attention and minimizes the risk of one-handed handle operation. be able to. In addition, when the horn can be operated safely and safely, the sound can be produced with the conventional behavior.
