Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a self-power generation safety warning device particularly suitable for a motorcycle.

[0002]

2. Description of the Related Art A bicycle is required to have a reflector to prevent accidents at night.

[0003] As a general reflector, there is an integrated reflector in which the outer peripheral edge of a reflector is welded to the opening edge of the case by ultrasonic waves, heat or the like so that the inside of the case is sealed. Are known. At the time of mounting, mounting can be performed by fixing the mounting member provided on the back side of the case to a frame or the like with the reflecting plate facing backward.

[0004] As a result, the headlights of the vehicle approaching from behind are reflected by the reflector, so that it is easy to recognize the presence of the bicycle, thereby preventing accidents and the like.

[0005] However, such a reflector functions only when there is light radiated from outside, such as a headlight of a vehicle. For example, when a vehicle or the like approaches without lights at night, Not only is there a very high possibility that it is difficult for the driver to recognize the presence of the bicycle, but also there is a possibility that the presence of the bicycle will be difficult to recognize even if the driver is added to the surroundings.

Therefore, there has been proposed a safety device which can enhance safety by incorporating a warning light which emits light by itself without receiving light emitted from the outside. That is, a warning light is provided above a reflector composed of a case and a reflector so that light from the LED is emitted by a reflection mirror provided inside the case. Since this warning light is lit by obtaining power from the separately attached battery case side through a cord, the function of the reflection plate and the above-described function for a vehicle or the like at the time of non-lighting are not performed. It can also have a recognition function and has extremely high security.

[0007]

However, in the above-described reflector, the amount of light reflected by the reflector is determined by the JIS standard, and the amount of light reflected when oil or dust adheres to the back side of the reflector. Therefore, it is required by the JIS standard to fix the case and the reflection plate in a sealed state. For this reason, it is impossible to form a hole or the like for attaching an accessory or the like to the case, so that there is a problem that restrictions are increased in appearance, structure, and design.

Further, the size of the reflector needs to be a certain size due to the limitation of the amount of light reflected by the reflector, and the elimination of the reflector is a violation. Therefore, when a warning light is incorporated in the reflector, it is inevitable. The size of the safety device itself becomes large. Such an increase in size of the safety device itself
Except when mounted on the rear fender, it is not preferable because it is easily damaged when it falls down, and tends to get in the way when putting it in and out of a bicycle parking lot.

Further, in order to illuminate the warning light, power is obtained from the separately attached battery case side. Therefore, when the battery runs out, the battery needs to be replaced. In many cases, the replacement of the battery is not performed due to troublesome replacement of the battery, and it is expected that the original function of the warning light will not be performed. Further, in order to obtain power from the battery case side, it is necessary to route the cord to a tire guard or the like, so that not only mounting becomes difficult, but also there is a problem that restrictions on mounting locations are increased.

The present invention has been made in view of the above circumstances, and a magnetic body is attached to an arbitrary portion of a rotating body such as a wheel, and the magnetic body is generated in accordance with the periodic approach of the magnetic body generated with the rotation of the rotating body. By causing the safety warning light including the light emitter to emit light by electric power induced in the magnetic circuit attached to the frame via the attachment member made of the magnetic material,
Providing a non-contact self-powered safety warning device that promotes efficient power generation, greatly reduces design constraints and installation constraints, and can be downsized without sacrificing safety. The purpose is to do.

[0011]

According to a first aspect of the present invention, there is provided a rotary member having a magnetic body attached thereto, and a rotary member provided between the rotary member and a central portion of the rotary member. Frame, and a safety warning light including a luminous body that emits light when the rotating body rotates, and at an arbitrary position of the frame facing the magnetic body, via a mounting member formed of a magnetic material. A magnetic circuit is attached, and the light-emitting body is caused to emit light by electric power induced in the magnetic circuit in accordance with the periodic approach of the magnetic body caused by the rotation of the rotating body.

[0012] Thus, the mounting member also serves as a magnetic circuit, and the induced electromotive force is enhanced, so that efficient power generation is possible and a safety warning device that does not require battery replacement can be provided.

According to a second aspect of the present invention, in the contactless self-powered safety warning device according to the first aspect, the luminous body and the magnetic circuit are connected via a flexible cord.

As a result, even when the steering wheel is rotated at a large angle, there is no squeezing or disconnection, and the flexible curl cord absorbs the force. It becomes something.

According to a third aspect of the present invention, in the non-contact self-powered safety warning device according to the first aspect, the magnetic body is attached to a rotating body. According to a fourth aspect of the present invention, in the non-contact self-powered safety warning device according to the first aspect, when the rotating body is formed of a resin tire, the magnetic body is integrally formed with the resin tire. I decided that. Furthermore, the invention according to claim 5 is the non-contact self-powered safety warning device according to claim 1, wherein when the rotating body is formed by a wheel with a spoke, a hole through which the spoke passes through the magnetic body. Is formed and fixed through the hole.

[0016] Accordingly, the safety warning device can emit light in accordance with the periodic approach of the magnetic material, and it is not necessary to route a cord for supplying electric power to the light-emitting device, which greatly restricts installation. Can be relaxed.

The operation of the embodiment of the present invention shown in FIGS. 1 and 2 will be described with reference to FIG. First, the magnetic body 3 approaches the magnetic circuit 2 with the rotation of the rotating body 1. In the magnetic circuit 2 including the attachment member 23 to the frame 4, an induced electromotive force is generated as the magnetic body 3 approaches, and the power is transmitted to a safety warning light (not shown) via the flexible curl cord 25. FIG. 3 shows the flow of the magnetic flux at that time by a broken line. Here, it is described that the presence of the attachment member 23 allows more efficient power generation than the magnetic coil 21 alone.

FIG. 4 shows a configuration in which the non-contact self-powered safety warning device of the present invention is applied to a recently popular kick board. Here, a safety warning light 5 is attached to an arbitrary position of a frame 4 connected to a handle 6 while supporting the vicinity of the center of the vehicle body with the body serving as the rotating body 1 therebetween. The above-described porcelain circuit 2 is attached to the end of the frame 4, and the magnetic circuit 2 is attached to an arbitrary position of the vehicle body in accordance with the periodic approach of the magnetic body 3 bonded with double-sided tape, for example, as the vehicle body rotates. Is induced in the power. The electric power induced here is transmitted to the safety warning lamp 5 via the flexible curl cord 25, and the internal light emitting body emits light.

As described above, according to the present invention, the magnetic circuit 2 is mounted on the frame 4 at an arbitrary position facing the magnetic body 3 through the mounting members 23 and 24 made of a magnetic material. In accordance with the periodic approach of the magnetic body 3 accompanying the rotation of the motor, the safety warning light 5 is generated by the electric power induced in the magnetic circuit 2.
This makes it possible to provide a non-contact self-power generation type safety warning device capable of realizing efficient power generation.

Although the safety warning light 5 has not been described in detail with respect to the internal configuration and the like, the type is particularly limited as long as it has a light emitting body such as an LED and emits light by electric power obtained from the outside. It doesn't matter. Also, when the rotating body is formed of a resin tire, a magnetic body is integrally formed with the resin tire, and further, when the rotating body is formed of a wheel with spokes, a hole through which the spoke passes is formed in the magnetic body. However, it can be replaced by attaching and fixing through the hole.

Further, in the embodiment of the present invention, only the recently popular kick board has been exemplified. However, the present invention is not limited to the kick board. Equipment can be provided. The present invention has a remarkable effect particularly when used for a vehicle body on which a traffic weak person rides, such as a wheelchair, an infant car, and a tricycle.

[0027]

As described above, according to the present invention, since the mounting member also serves as a magnetic circuit, the electromotive force induced more than the magnetic coil alone exists is increased, so that efficient power generation is achieved. Can be made possible. Also,
The light emitting operation can be continued with the periodic approach of the magnetic material, and the self-power generation function and the light emitting function can be continued semipermanently.
Furthermore, unlike the conventional case, it is not necessary to route a cord for supplying power to the illuminant, so that the restriction on the mountability is relaxed. In addition, the flexible curl cord absorbs the force, so that it is possible to flexibly cope with it, and the appearance is fashionable.
