Abstract

PURPOSE:To decrease contact required for flashing of direction indication by providing a flashing means which is intermittently supplied with power from power source through a knocking element and a knocked element and flashes when knocking a knocked element intermittently with a knocking element at time of left turn or right turn of a vehicle. CONSTITUTION:When a switch S is turned on with a contact Sb at time of left turn, an oscillating circuit part 80 oscillates and an electromagnet 60 intermittently generates suctional magnetic force. Then, a magnetic plate 65 is sucked to a core 62 and displaced and a knocking element 70a intermittently knocks a knocked element 70b. Hereby, a diaphragm 30 vibrates and generates an alarm sound. Further in this intermittent knocking condition, a directional indication light L1 is intermittently supplied with power from power source B through a switch 1G, a knocked element 70b, a knocking element 70a and a contact Sa, Sb and flashes. Accordingly, there is no need to provide, in particular, a contact required for flashing the directional indication.

[Prior art]

Conventionally, in this type of direction indicating device,
As disclosed in Japanese Patent No. 5227, a diaphragm is placed above the suction end surface of the electromagnet via a magnetic plate fixed to the armature, and a movable contact is fixed to the tip of the lower surface of the armature, and the suction of the electromagnet is A fixed contact is fixed to the end surface, a striking element is fixed to the center of the upper surface of the armature, and a struck element is fixed to the center of the lower surface of the diaphragm, so that the magnetic plate moves downward or upward in response to the intermittent attractive magnetic force of the electromagnet. When deflected, the movable contact intermittently contacts the fixed contact to flash the direction indicator light, and the striking element intermittently strikes the struck element, causing the diaphragm to generate a warning sound due to its vibrations. It is something.

[Problem that the invention seeks to solve]

However, in such a configuration, a movable contact and a fixed contact are required for blinking the direction indicator light, and a striking element and a struck element are required for generating a warning sound, so electromagnets, armatures, and diaphragms are required. The problem is that the configuration becomes complicated, leading to an increase in production costs.

Therefore, in order to cope with this problem, the present invention attempts to provide a vehicle direction indicating device in which the above-mentioned striking element and struck element also serve as a contact point necessary for blinking the direction indication. It is something.

[Means for solving problems]

In order to solve this problem, the present invention has an operating means that is operated when the vehicle turns left or right to enter the first or second operating state, and an operating means that is operated in the first or second operating state of the operating means. an electromagnet that is excited in response to the oscillation output generated from the oscillation means and intermittently generates an attractive magnetic force; a magnetic plate that is intermittently attracted to the suction end and deflected in one direction or the other under the elastic action of an elastic means; and a magnetic plate that is arranged to face the suction end of the electromagnet through the magnetic plate. a diaphragm that generates a warning sound by vibration; a conductive striker that is fixed to a part of the surface of the magnetic plate facing the diaphragm and deflected integrally with the magnetic plate; an electrically conductive hit element fixed to a part of a surface facing the magnetic plate facing the striker and intermittently struck by the striker to vibrate the diaphragm; and a first operating state of the operating means. a first blinking means that blinks by being intermittently supplied with power from a power source through the striking element and the struck element when the struck element is intermittently struck by the striking element, and a second operating state of the operating means. and a second flashing means that is intermittently supplied with power from the power source through the striking element and the struck element to blink when the striking element is intermittently struck by the striking element.

[Effect]

By configuring the present invention in this manner, when the vehicle turns left (or right), the operation means is set to the first position.
(or the second) operation state, the electromagnet is excited in response to the oscillation output from the oscillation means and intermittently generates an attractive magnetic force, and the magnetic plate responds to the intermittent attractive magnetic force. is intermittently attracted by the suction end of the electromagnet and deflected in one direction or the other, and the striking element intermittently strikes the struck element in accordance with the deflection of the magnetic plate in one direction or the other direction. The first (or second) blinking means blinks in response to the intermittent striking contact of the striking element with the struck element, and the diaphragm causes the intermittent striking contact of the striking element with the struck element. It vibrates and emits a warning sound in response to a target strike.

〔effect〕

Due to the above-mentioned action, the first (or second)
Based on the flashing of the first (or second) flashing means, it is possible to instruct the vehicle to turn left (or right), and the flashing of the first (or second) flashing means can be confirmed by the warning sound from the diaphragm. In such a case, the generation of a warning sound from the diaphragm and the intermittent power supply to the first (or second) flashing means from the power source are both performed via the striking element and the struck element. Therefore, the structure of this type of device becomes simple and production costs are reduced.

[Example] Hereinafter, an example of the present invention will be described with reference to the drawings.
2 and 2 show the overall configuration of a vehicle direction indicating device according to the present invention. Operation switch S connected to the five-body body
and a pair of direction indicator lights L connected to this device switch S.
The operation switch S is composed of J and L.
When the vehicle turns left (or right), the double throw contact Sa is thrown into the fixed contact Sb (or Sc).

Turn signal light LI! receives intermittent power supply from the fixed contact sb of the operation switch S as described later and blinks.

On the other hand, direction indicator light 1. r is the fixed contact S of the operation switch S
c receives intermittent power supply as described later and blinks.

As shown in FIG. 1, the main body of the device includes a cylindrical housing 10 and a cylindrical casing 20. It is fitted in the inner upper part. The flange portion 11 of the housing 10 includes
A diaphragm 30 made of a gold-plated disc is placed to close the opening of the housing 10, and the diaphragm 30 is attached to the flange of the housing 10 by caulking from above with a cover 50, together with an insulating disc 40 superimposed on the upper surface of the diaphragm 30. It is held between the parts 11 and 11.

An electromagnet 60 is housed within the casing 20,
This electromagnet 60 consists of a yoke 61 fixed to the bottom wall of the casing 20, a columnar core 62 erected at an intermediate portion of the bottom wall of the yoke 61, and a core 62 wound around the core 62 through a bobbin 63a inside the yoke 61. Electromagnetic coil 63 and yoke 61
An L-shaped armature 64 made of an elastic conductive material is fixed to the L-shaped arm 61a of the diaphragm 30 and the suction end surface 62a of the core 62 is fixed to the lower surface of the distal end of the armature 64. A striking member 70a made of a conductive material is provided on the top surface of the tip of the armature 64, and a striking member 70a is provided with a magnetic plate 65 located in parallel with the diaphragm 3.
A hit element 70 made of a conductive material fixed to the center of the lower surface of the
b, and selectively separates and releases the striking member 70b (fixed thereto). In FIG. 1, the reference numeral 10a indicates a fixture, and the reference numeral 10b indicates a terminal box.

An oscillation circuit section 80 is accommodated in the bottom of the housing 10, and the membrane circuit section 80 transmits the oscillation to the electromagnetic coil 63 with each conducting wire 81, 82, as shown in FIGS. 1 and 2.
are connected to the struck element 70b by a conductive wire 83, and to the ignition switch IG via one of the plurality of terminal terminals t. Further, the oscillation circuit section 80 includes both conducting wires 84.8.
5 to the lower end of the armature 64, and is also connected to the double-throw contact Sa of the operating switch S via the other terminal t. Thus, the oscillation circuit unit 80 oscillates and intermittently excites the electromagnetic coil 63 when the operation switch S is operated while the ignition switch IG is closed.

This means that the electromagnet 60 intermittently generates an attractive magnetic force on the attractive end surface 62a of the core 62 due to the intermittent excitation of the electromagnetic coil 63.

In this embodiment configured as described above, when the double-throw contact Sa of the operation switch S is connected to the fixed contact sb in order to turn the vehicle left while the vehicle is running with the ignition switch IC closed, the oscillation circuit section 80 is supplied with power from the DC power supply B through the ignition switch IG and oscillates, and the electromagnet 60 is activated by the excitation of the electromagnetic coil 63 that responds to the oscillation of the oscillation circuit section 80, thereby causing the attraction end surface 62a of the core 62 to oscillate.
generates an attractive magnetic force intermittently. Then, the magnetic plate 65 is intermittently attracted to the suction end surface 62a of the core 62 under the elastic action of the armature 64 and is deflected downward or upward, and the striking element 70a is moved under the elastic action of the armature 64. Then, the hit element 70b is intermittently hit, and in response, the diaphragm 30 vibrates and generates a vibration sound as a warning sound. In addition, in the intermittent hitting state of the hit element 70b by the impact 70a as described above, the direction indicator light LA is switched from the DC power source B to the ignition switch IG to the hit element 7.
0b, striker 70a, double throw contact Sa of tM switch S
The light is intermittently supplied with power through the fixed contact sb and blinks.

As a result, even if it is possible to instruct the vehicle to turn left based on the blinking of the direction indicator light LA, the blinking of the direction indicator light L6 can be confirmed by the warning sound from the diaphragm 30. In such a case, since both the generation of the warning sound from the diaphragm 30 and the intermittent power supply from the DC power supply B to the direction indicator light L1 are performed via the striking element 70a and the struck element 70b, an extra contact point is employed. This simplifies the construction of this type of device and reduces production costs. Note that the above-described effects can be similarly achieved even when the double-throw contact Sa of the operation switch S is closed to the fixed contact Sc.
