TECHNICAL FIELD OF THE INVENTION

This invention relates to safety light systems and is used in vehicles, especially motorcycles.

[Prior Art and Problems to be Solved by the Invention]

Safety is very important for motorcycle riders. Safety is even more important for motorcycle riders than for passenger car drivers because the motorcycle structure itself does not adequately protect the rider. Normally, motorcycles cannot use roll bars, technology for absorbing impact at the time of collision, airbags in the driver's seat, side airbags, and the like. Formerly the Australian Federal Road Safety Agency (FO
According to the Australian Bureau of Road Safety, known as RS), motorcycle riders are 20 times more likely to die or be seriously injured as a result of a collision than other types of vehicle drivers.

Due to its smaller body than other types of vehicles, the main cause of accidents is that the motorcycle is hard to see. As a result, it was decided to keep the headlights on even during the day. Since 1996, Australia has been strongly encouraged to use wiring that automatically switches on the headlights when the engine is started.

However, such a system can only see the lights of the motorcycle in the oncoming lane and in the cars crossing the road on which the motorcycle is traveling, so that the cars behind the motorcycle cannot be seen. Useless. The ratio of accidents when the headlights were not lit and when they were lit was statistically similar.

Another approach is to attach a safety light to the pole behind the motorcycle.
The light has a yellow translucent cover on the front and a red translucent cover on the back. In this system, the light turns on automatically when the engine is turned on and remains on while the engine is on. This made the car visible right in front of and behind the motorcycle look better, but it was useless for cars in front of and behind it.

[0006] Motorcycle driving is of concern for other vehicles, especially 22-wheel semi-trailers, large four-wheel-drive vehicles, caravans, and towed boats.
It is when driving in front of a large car. If another car follows behind such a heavy vehicle, the driver is irritated that he believes the large vehicle is slowing down, overtaking, and in the last moment, in front of the large vehicle for the first time. You may face a motorcycle traveling in. A rear-end collision occurs when you do not have the time to pass a motorcycle or when you do not notice the motorcycle.

There is a high risk of a collision accident at night or in a wet state. Usually, in a collision accident between a passenger car and a motorcycle, the larger car is advantageous in the law of momentum, so that the motorcycle and its rider are greatly damaged.

According to the Australian Federal Office for Road Safety (FORS) announcements in 1992 and 1994, 24% of accident deaths caused by motorcycles were caused by motorcycles alone (excluding pedestrian accidents). . 68% of accidental deaths occur in rural areas. There was no single accident at the intersection. 55% jumps off the road at a corner, 1
9% jump out straight roads, 10% collide with animals, 6% lose control when overtaking, and the remaining 10% are due to various other reasons.

A collision can involve one or more factors. 87% of single collisions are due to motorcycles. Two-thirds of them were driving dangerously in the event of a collision. 5
9% is too fast, and a third is due to driving mistakes. 26% of the accidents were caused by the fact that the rider had a temporary license or had just acquired a license and could not cope with the immediate situation. There are many relatively inexperienced riders who die from motorcycle accidents, lose control at the corner of a rural road, and often drive too fast even under the speed limit in that situation.

Since there are many motorcycle accidents and there is a high possibility that the rider and the motorcycle will jump off the road, there is a clear need for a warning or instruction transmission system that can give instructions to a passing vehicle or a rescue team. In particular, a warning system is necessary when the rider is fainting on the road and a car approaching due to darkness causes a more fatal accident.

Known safety light devices are usually not suitable for emergency alerts. When a motorcycle is involved in a collision, the protruding parts of the motorcycle are almost always destroyed. FORS published its research report CR174 in December 1997. this is,
Reported by Haworth N, Smith R, Blumen I, and Pronk N, entitled "Motorcycle Collision Contrast". According to the report, accidents can damage the indicator lights, safety lights, headlights, and rear lights, with 50% of all accidents being damaged. In addition, the engine must be running for the lights to be on after the accident.

According to the FORS report, 40% of single accidents occur at night in the absence of streetlights. In many cases, it is a remote area where no cars pass by. In the event of a loss of control on a wet or poor road resulting in a solitary traffic accident, the motorcycle may be thrown off the road and collide with an object by the road. The engine shuts down, the turn signals, headlights and rear lights are damaged, and the motorcycle is thrown into the darkness beside the road. In 88% of these situations, the rider is injured and there is no way to seek help from a passing car. Passing cars may pass without rescue, missing what is indicative of a motorcycle accident. Alternatively, if a rider or motorcycle is thrown into the path of the car, another car may cause further injury.

Furthermore, according to the FORS research report CR174, motorcycle rider injury is 4
% Is the head, 44% is the upper limb, and 57% is the lower limb. The most common injuries are knee and lower leg fractures (28%) and forearm fractures (17%). Because of this, the rider cannot ask for help and often has to wait until someone notices.

[0014]

[Means for Solving the Problems]

Therefore, an object of the present invention is to provide a safety light system that can give an instruction in an emergency even if a normal turn signal light is damaged.

Furthermore, it is an object of the invention to provide a safety light system which serves to indicate the presence of a motorcycle, especially under adverse conditions.

According to the invention, the light of the safety light system is mounted in a protected part on the underside of the vehicle. The lights can be activated so that the lights illuminate the road beneath the motorcycle while driving, or at a slight angle to illuminate the road around the vehicle. If possible, the illuminated area should be larger than the size of the vehicle and smaller than one lane of the road.

On the other hand, the lights located under the vehicle are activated when an emergency situation is detected. This is detected by things like motorcycle tilt sensors and crash sensors.

A motor vehicle having a ground wheel and a frame provided between the ground wheels, the motor vehicle including a battery and at least one light utilizing the battery, the light comprising a collision of the motor vehicle. It is installed in a place that is not destroyed even at times, and illuminates the outside of this motor vehicle.

The light operates during traveling and illuminates a limited area below the main vehicle and illuminates roads around the main vehicle. The illuminated area of the road is larger than the size of the motor vehicle and smaller than one lane of the road.

The starting system of the safety light system is a two-mode type, one first mode is for road lighting during normal operation of the motor vehicle, and the other second mode is for emergency use. Activate the system to activate the emergency light.

The invention also proposes a method of providing a safety light system for a motor vehicle, which method comprises: (a) determining at least one protective mounting position of the motor vehicle; Providing a light in a mounting position; (c) connecting the light with a power source; and (d) providing a starting system for operating the light to cause the light to illuminate the outside of the motor vehicle. The steps include and.

The step of mounting the light causes the light to illuminate the lower part of the motor vehicle, and does not allow the illumination light to directly illuminate the eyes of another person in the front or rear.

The step of providing the activation system provides a sensor for emergency detection and activates the light upon detection of emergency. The sensor includes a motor vehicle tilt indicator.

As one form of the present invention, a safety light system for a motorcycle is proposed, which system: (a) flashes below 2 hertz, under a seat, pinion seat or seat extension, or on a motorcycle. The strobe light is a size that can be installed in a protected place in the frame of, and is provided so as to avoid destruction in an emergency, and (b) independent of the power of the motorcycle, strobe operation that operates for 2 hours or more It includes a battery, and (c) an inclination sensor capable of detecting an emergency inclination, and an activation system for detecting an emergency and activating the strobe light.

The activation system is a two-mode type, one first mode is for emergency road lighting, the other second mode is for emergency, and the safety light system is operated to turn on the emergency light. Light up.

The safety light system for a motorcycle of the present invention includes: (a) a strobe light that is flashable at 2 hertz or less and can be mounted under a seat, a pinion seat or a seat extension, or in a frame of a motorcycle; (b) a battery for the strobe light; and (c) a starting system for activating the strobe light, which allows the light to illuminate a limited area of a road below the motorcycle when the motorcycle is running. , Lighting the road around the motorcycle.

Therefore, the safety light system according to the present invention can clearly present the presence of a motorcycle to nearby cars. You can use your motorcycle more safely in wet or foggy conditions, and even give an emergency warning in the event of a collision. The system works automatically and can be used for hours. Since the lights are in a protected position, the lights will not be broken in a collision or a single accident in which a turn signal, a brake light or other lights are destroyed.

The present invention also includes an improved tilt indicator for use in activating an alarm system, such as a safety light system.

DETAILED DESCRIPTION OF THE INVENTION For easy understanding of the invention, the invention is illustrated by way of illustration: The construction of a motorcycle has a conventional cradle U-shaped for the location of the engine. Some use shaped frames. The frame is made of steel tubing welded to the wheel or cradle, with the engine at the bottom of the wheel. This form of frame allows designers to try various engine and other modifications, is made to form a motorcycle chassis, and must withstand bending, breakage, impact and be as light as possible. I won't. In front of the cradle frame is a fork mount with a front fork that connects to the front wheels of the motorcycle. In this structure,
A very well protected area in front of the cradle behind the front fork below. The cradle-shaped frame extends rearward to form the rear part to which the seat is attached, but again below the seat and above the rear wheels, providing another protected location.

The second construction of the motorcycle is a single Y-shaped spine type using a square tube of steel alloy. The engine is cantilevered on the lower front of the frame. Also in this structure, the front of the spine-shaped frame, which is below and behind the front fork attached to the fork mount, is a protected place.

The third structure is a spine-like structure in which the engine is mounted on or around the spine. This type of structure can use non-metallic light materials.

The structure of a motorcycle is considered to have these three modes, but each has a minimum of 2
There are protected areas in the open areas.

In FIG. 1, one style of motorcycle 11 is depicted, which utilizes a cradle-shaped frame mounted between front wheels 13 and rear wheels 14, which may be a straight-based triangle or It has a trapezoidal shape. The engine 23 is mounted on the lower side of the frame, with the gasoline tank 22 and seat 24 at the top. The front fork 26 extends from the fork mount at the top point of the frame,
9 also extends from the top point of the frame. In front of the handlebar is a windscreen 27, which is attached to the top of a streamlined molding 28. This molding covers the entire front part of the frame and the motorcycle 1
Spread to the bottom of 1. For motorcycle controllability, the bottom of the front molding 28 has ample ground clearance and tapers toward the center.

The light includes a headlight 16, a taillight 17, and turn indicators 18 and 19, which are mounted on a motorcycle. Headlights 16 are attached in front of the front molding 28 and above the front wheels 13. The front left and right indicators 18 are attached to the outside of a front molding 28 that continues above the front wheels 13. The taillight 17 is attached to the end of the seat 24 and the rear seat 25. The rear left and right indicators 19 are mounted on brackets that are hung on the rear seat 25 on both sides of the vehicle body above the rear wheels 14. As you can see, all the lights are on the tip of the motorcycle. This is particularly effective for informing a vehicle around the motorcycle of the behavior of the motorcycle and future actions during normal driving. However, in the event of an accident, these lights will be damaged or destroyed.

It can be seen that the protected location 32 is at the front of the frame, behind the front fork 26. Therefore, the light attached to the location 32 will not be damaged due to a rear-end collision with a tree or the like that causes damage to the front headlight 16. The second protected area is indicated at 35 and includes the lower part of the seat 24, the upper part of the frame and the gas tank 2
It is a place extending from the rear side of 2 to the rear side. Since it is far from the rear of the motorcycle, the rear-mounted lights 17 and 19 will not be affected by a rear-end collision or a roadside fixed object that destroys the rear lights 17 and 19. If the motorcycle slips, the locations 32 and 35 are protected, but the headlights 16, taillights 17 and turn indicators 18 and 19 on the tips are broken.

FIG. 2 shows a modern version 12 of a trail bike, which is used on a dirt road and a side road. This structure is similar to the frame structure of FIG. 1, but there is no euphem at the rear of the frame around the rear wheel 14. Instead, a fluttering part is attached to a portion extending straight from the front gasoline tank 52 through the seat 58 to the rear portion 59 of the vehicle body. The vehicle body tail 59 is located above the rear wheel 14 and the muffler system with a space therebetween. This creates a space 65 below the rear tail 59 of the vehicle, which is more protected than the position of the rear lights 17 and 19 at the end of the motorcycle 12. Further, the direction indicator 19 is projected laterally from the side surface of the motorcycle 12,
Often protrudes from the outline of the entire side surface of.

The front of the modern version of the motorcycle 12 has no protected area in front of the frame because of the large radiator and streamlined molding. However, every motorcycle has at least one protected area, which is usually located below the seat and near the rear.

For some motorcycles, another protected location may be in the lower portion of the frame. This location is adjacent to the lower protected area. When skidding, protection of the safety light system sometimes requires a mounting mount around the light that can be mounted on the bottom of the frame.

From the above, it is clear that there is a protected place for safe and effective mounting of an emergency safety light system according to the present invention, which has never been used, especially for motorcycles. Is.

FIGS. 3, 4, and 5 are schematics of the three major components of the emergency safety light system, in which the lights are mounted in protected locations 32, 35, 65 or other protected locations. Lights are good strobes, preferably 1-2 x Hertz, or xenon strobes that flash 90 to 120 times per minute, causing epileptic seizures 10
To less than 30 hertz. The xenon strobe requires a 3 watt output, 12 volt DC, current consumption of 180 mAmps, and a trickle charge of 10 to 20 mAmps. The color of the lens may be transparent, yellow, blue or red, but yellow is preferable. With a diameter of 80 mm and a height of 31 mm, it can be easily installed in protected areas 32, 35, 65 or other protected areas.

The second main element is the battery 82. The usual lights on motorcycles 11 and 12 are connected to the main battery of the motorcycle, so the lights will not come on when the engine shuts down after a collision. If the engine was turned off and the lights were on, the battery would last for about 15 minutes, then the lights would go out. The battery 82 used in the emergency safety light system according to the present invention is a sealed lead acid battery and has a performance of 12V DC and 1.3Amp time. Maximum charging current is 0.65 Amps. A diode is used to ensure that the current only flows in one direction and to prevent the battery 82 from draining due to other electrical drains on the motorcycle. Furthermore, the use of diodes ensures that the power of the motorcycle's ordinary battery is used before the power of the battery 82. It was assessed that a xenon strobe could blink for up to 7.2 hours using such a battery system. The battery measures 43 mm x 95 mm x 50 mm, weighs 600 mg,
Easily attached to protected locations 32, 35, 65 or other protected locations.

The third major element of the emergency safety light system is the sensor 83. It is necessary to activate the protected light 81 in the event of an accident. Sudden deceleration sensor,
A shock sensor or a sensor in an abnormal operating condition is good. However, in the event of a motorcycle accident, it is common for the motorcycle to fall sideways. Therefore, the tilt indicator
83 is desirable as a sensor. It has two mercury tilt switches 91 and 92 wired in the circuit, as shown in FIGS. 5A and 5B. Mercury tilt switch
A small elongated capsule containing mercury as a conductor with electrical connections. Tilting the switches 91 and 92 to a certain position, the liquid mercury completes the circuit,
Switch on the emergency safety light system. Two mercury switches 91 and 92 are symmetrically attached to the case 93 in the foam substance 94 so that the tilt switch operates regardless of which side the motorcycle falls over. Is located. The safety device is made around the axis of symmetry S. The axis of symmetry S is in its normal vertical operating position when the sensor is properly mounted on the motorcycle. Mercury tilt switch 91
The angles of and 92 from the axis of symmetry S are angle A and angle B, respectively, which is equal to or greater than the normal tilt angle when the motorcycle is turning a curve. Therefore, it operates only in abnormal conditions or in the event of an accident.

To limit the emergency safety light system to accidental operation, a motorcycle ignition system can be wired to this system. Then it only works when the motorcycle is running.

The lights 81 are located in protected areas 32, 35, 65 or other protected areas, but are mounted externally where the lights are visible from outside the motorcycle. The system is protected in the event of an accident and serves the function of alerting nearby people and drivers of vehicles passing by, regardless of the state of the rider, of the catastrophe. After doing so, I believe that rescue will be obtained sooner than it would be without the system, and it would prevent further catastrophes.

With this system improvement, it is also possible to install a sound alarm such as a micro piezo siren with a sound output of 120 decibels per meter, a DC 12 volt power supply, and a current consumption of 350 mAmp. Alternatively, it can be connected to a wireless signal generator or mobile phone system. Connected to a global positioning system or mobile phone triangulation, the recipient can determine the location of the accident and provide appropriate assistance.

There is an important second safety element in the emergency safety light system of the present invention. In other words, because the light is installed outside, it is possible to illuminate the light downwards and slightly outward, creating an aura of light around the contour of the motorcycle, which can strongly inform the existence of the motorcycle. The light does not illuminate the front or back, so it does not affect other drivers. The aura is very useful for informing the presence of a motorcycle when it is wet, or between other vehicles, such as when the size of another vehicle hides the motorcycle. The light significantly enhances the safety of the motorcycle as it allows the presence of the motorcycle to be noticed without disturbing other drivers.

If the motorcycle encounters an accident on a lonely road or a single accident, a sensor such as a momentum indicator or a tilt indicator detects a collision and the strobe operates.
That is, when the inclination of the motorcycle exceeds the maximum value determined in advance, it is detected that the motorcycle is in a sideways state, that is, in a collision position.

A V-shaped groove can be used for the inclination mechanism. In this mechanism, the ball bearing is located in the groove, and current is conducted when the ball bearing reaches the top of either of the V-shapes due to the movement due to gravity. This is when the motorcycle is at a critical angle, or in a collision. The motorcycle is also lying sideways. Since this mechanism is not constant, two straight grooves are attached to the top of the V-shape, and when the motorcycle goes beyond the critical angle, a grain of mercury or a metal ball at the top Kind of things pass the current. The top of the V-shape can be fitted with an ingestion part so that mercury particles or metal balls must pass over the top of the V-shape for current to flow. This will reduce the activation of the warning system due to motorcycle vibrations. However, the use of multiple tilting mechanisms and multiple electrical processes can eliminate or minimize vibrational activity, making the device more reliable.

As a variation of the invention, the system can provide variable tilt sensing by providing electrical contacts in the groove. As a result, the inclination can be continuously displayed on the motorcycle rider by the display device, in addition to the ordinary speedometer, tachometer and the like. It can be set in advance based on the structure of the motorcycle, the structure of the tires, the size of the motor, the experience of the rider, and the tilt angle up to a critical angle at which the rider cannot control the motorcycle can be displayed step by step. The gradual input allows particularly inexperienced riders to lean the motorcycle above the critical angle and get used to the maximum allowed tilt angle without actually falling too much. This display mechanism can be adjusted by wet conditions, tire changes, riders, etc. Especially on windy roads or on swelling roads, it is necessary to drive at an inclination angle that is very close to the critical angle, and it is necessary to adjust the inclination measuring device so that sound and visual warnings do not work. is there.

This tilting mechanism is part of the mechanism of the safety light and is attached to the previously mentioned protected part.

From what has been said above, it is clear that the invention enhances the safety of motor vehicles, especially motorcycles. Modifications of the above specific invention contents can be easily considered by an engineer and are included in the scope of the present invention. For example, if you attach a safety light system to a tilt mechanism, when the motorcycle leans at a corner, the light system leans and illuminates downwards, causing light to reflect off road surfaces, especially wet road surfaces, creating an aura around the motorcycle. it can. This mechanism prevents the light from hitting oncoming vehicles. Other modifications are within the scope of this invention, as defined in the claims below.
