Description

[Detailed Description of the Invention] [Industrial Application Field 1] This invention relates to a helmet that is legally required to be worn by an occupant of a motorcycle, etc., and specifically relates to a helmet that is legally required to be worn by an occupant of a motorcycle, etc. This relates to a helmet that prevents contact with other vehicles, collisions, etc.

[Prior Art] Accidents involving motorbikes and other vehicles have been occurring frequently, and there is an urgent need to prevent such accidents. Since it has become legally mandatory to wear a helmet when driving such a car (even in the event of an accident, the driver's head is protected by a helmet, and due to its protective function42, the material of the helmet is , divine improvements have been made in terms of shape, structure, etc.

[4 Problems to be Solved by the Invention 1] However, helmets are originally designed to protect the driver's head from blows when an accident occurs, and are not intended to prevent accidents from occurring. . Therefore, with conventional helmets, no consideration has been given to increasing safety during normal driving, and prevention of accidents on motorcycles, etc. is left to the driver's driving skills and awareness of safe driving.

For this reason, motorcycles operated by inexperienced or erratic drivers are always at risk of accidents. For example, when riding a motorcycle in conditions of poor visibility, such as at night or on the street,
Despite cars driving nearby paying close attention to the bike, the bike suddenly slowed down, creating a risk of a collision, causing problems with driving safety.

Therefore, in the present invention, while protecting the head of a vehicle such as a motorcycle,
In order to improve driving safety, the helmet is equipped with a light-emitting device so that drivers of other cars can recognize the occupants even in poor visibility conditions, and the light-emitting device emits red light especially when the brakes are operated. , the technical problem to be solved is to make people aware of danger.

[Means for Solving the Three Problems] The technical means for solving the above problems is to provide a brake-sensitive helmet with a helmet body, such as a helmet, that is placed on the head of an occupant, and a red color that is provided on the outside of the helmet body. and a light emitting body that emits light in a color other than red; a first light emission driving circuit that supplies current to the light emitting body to cause it to emit red light; and a first light emitting drive circuit that causes the light emitter to emit light in a color other than red. a second light emitting drive circuit that supplies current; and a second light emitting drive circuit that supplies current to the first light emitting drive circuit or the second light emitting drive circuit depending on the input signal. a υ control circuit that operates one of the light emitting drive circuits of the motorbike; and a wireless signal transmitter mounted on the motorcycle that transmits a wireless signal g based on a brake signal when a brake device equipped on a Moeki motorcycle or the like is operated. , when receiving the wireless signal, outputs a first signal for operating the first light emitting drive circuit to the control circuit;
and a non-8 signal receiving unit that outputs a second signal for operating the second light emission drive circuit to the GJ fIIt11 circuit when the ia sense is not received. .

In addition, the @Note III control circuit operates the first light emitting drive circuit and the second light emitting drive circuit intermittently, and is configured to include an oscillation circuit for causing the light emitting body to blink and emit light. The present invention is characterized in that a charging circuit is provided to ensure the light emitting time so that the red light emitted from the light emitting body can be recognized even when the brake in is instantaneously operated.

1. According to the brake-sensitive helmet configured as described above, when the helmet body is placed over the head of an occupant of a motorcycle, etc., and the brake system is not operated, the wireless signal transmitter Since the wireless signal is not being output, the wireless signal transmitter outputs the second signal to the control circuit. Therefore, the control circuit operates the second light emission drive circuit, and the second light emission drive circuit supplies current to the light emitting body to cause it to emit light in a color other than red. As a result, the light emitter emits a color other than red, making other drivers aware that the vehicle is traveling even in poor visibility conditions, such as at night or during the day.

On the other hand, when the brake device is operated, a wireless signal is output from the M-ray signal transmitter, so the hot-ray signal receiver receives υIt[
A first signal is output to one circuit.

In order to do this, the υ11 circuit operates the first light emission drive circuit, and the first light emission drive circuit supplies a current to the light emitting body to cause it to emit red light. As a result, the light emitter emits red light, allowing drivers of other skewers to recognize that a brake operation has been performed.

Further, when the oscillation circuit is provided in the til control circuit, the light emitting body blinks and emits red or a color other than red. Historically, when the charging circuit is provided in the control circuit, even when the brake device is instantaneously operated, it is possible to secure a light emission time such that only the light emitting body can recognize the colored light.

An anti-copper plate 28 is provided on the upper surface of the light emitting unit main body 20, and reflects the lighting light when the red light emitting lamp R1 and the green light emitting lamp G1- are turned on.

As shown in FIG. 1, the aforementioned light projecting anti-noise 12 is provided at the rear end of the motorcycle 2. As shown in FIG. 4, the light projecting antenna 12 has its lower end fixed to a rack 44 at the rear of the motorcycle 2 with nuts 40 and 42, and extends upward in the vertical direction. For example, a light emitting diode (I) DI (
(see FIG. 6) is N&J, and a translucent lens 48 is placed over it. This lens 48 includes a light emitting diode P
It functions to converge and project the light emitted by D1 slightly diagonally upward and forward, and the light from here is received by the photodiode PD1 of the light emitter 10 as shown in FIG. It is now possible to do so. Incidentally, the mounting position of the light projecting anti-boo 12 is not limited to the rear of the motorcycle 2, but may be at the front.

Next, the electronic circuit shown in FIG. 6 will be explained.

When the driver 4 operates the brakes of the motorcycle 2, the light emitting circuit 51 in FIG.
The light emitting diode PCI is an electronic circuit configured to emit light.

The brake operating voltage BV is applied to the terminal T1. When applied to T2, not gate ■1, diode D1, resistor R1,
The oscillation circuit consisting of R2 and capacitor C1 oscillates a high frequency pulse wave, and the oscillation signal is sent to the not gate I2.
．． After being amplified by I3, C is applied to the base of the transistor TR1 via the resistor R3, and the transistor TRI is turned on and off in response to the high frequency pulse signal applied to the base of the light emitting diode 1]D1. It is designed to emit light modulated from the

The light emitted from the light emitting diode PDI attached to the light projecting antenna 12 is received by the photodiode PD2 mounted on the light emitting unit main body 20 as described above.

The light emitting circuit 51 is installed near the light emitting diode PD1 within the light projecting antenna 12, as shown in FIG.

The photodiode PD2 attached to the light emitting unit main body 20 is incorporated into a light receiving circuit 52, and the light receiving circuit 52 is printed and wired on the board 24.

When the modulated light from the light emitting diode PD1 is received by the photodiode PD2, the operational amplifier OP1 and the resistor R6
, R7, and R8, a voltage corresponding to the amount of light received is applied to the light receiving section (radio communication station receiving section). operational amplifier OP
When a voltage corresponding to the light reception 4 of the photodiode PD2 is applied to 1, the output voltage of the operational amplifier OP1 becomes positive, and therefore, the output signal of the amplifier circuit consisting of the operational amplifier OP2, the resistor R9, and the variable resistor VR2. becomes the logic r )-I J. On the other hand, when the light is not emitted from the light emitting diode PD1, no input signal is applied to the operational amplifier OP1, so the operational amplifier O
The output signal of P2 becomes f rLJ.

The output voltage of A beam OP1 becomes positive, and the operational amplifier O
When the output signal of P2 becomes logic “mouth”, diode D2
, is charged to the capacitor C2 via the resistor R10.

This charging circuit is a circuit for extending the lighting of the red lamp RL so that it can be visually recognized even if the brake operation by the driver 4 is extremely short.

Switch SW1 in the electronic circuit of FIG. As shown in FIG. 3, SW2 and SW3 have respective snap parts (operation parts) provided on the side surface of the light emitting unit main body 20, and can be set individually. Above switch S
W1. Behind SW2 and SW3, when only switch SW3 is turned on, the first contact 5W3 of switch SW3
-1 closes, and the second contact 5 of switch SW3
W3-2 is switched to the resistor R15 side. Contact 5W1-1 of switch SW1 is open, and switch S
The first contact 5W2-1 of W2 is in the state of being pushed down to the knot gate I5 side, and the second contact 5W of switch SW2 is
2-2 is in a state of being tilted toward the base side of the transistor TR3.

Note that when only the switch SWI is turned on, the green lamp GL is turned on, and when only the switch SW2 is turned on, the red lamp RL is turned on.

When only the switch SW3 is set to ON and the output signal of the A beam OP2 is a logic "gate", the charging circuit is charged, and the diode D2 and the switch SW3 are charged.
the first contact 5W3-1 of the switch SW2, and the first contact 5W3-1 of the switch SW2.
The input signal of the NOT gate I5 through the contact 5W2-1 becomes a logic "T1", so the output signal of the NOT gate I5 becomes a logic "L". Therefore, the oscillation circuit via the reversely connected diode D3, ie the not gate I6,
The oscillation circuit consisting of resistor R13 and capacitor C3 is
No oscillation signal is output from the knot gate I6,
A continuous signal of logic "mouth" is output. Therefore, the output signal of the NOT gate I7 becomes logic rLJ, and the transistor TR2 is in an OFF state, so the green lamp GL does not light up.

On the other hand, when the output signal of the operational amplifier OP2 is a logic "gate", the oscillation circuit consisting of the not gate 18, the resistor R17, and the capacitor C4 oscillates at the valve oscillation frequency determined by the resistor R17 and the capacitor C4, and the not gate I8 A pulse signal is output from.

Therefore, a pulse drive signal is outputted from the not gate I9 to the bases of the transistors r1-3, the transistors T'R3 are turned on and off at regular intervals, and the red lamp R1- is lit in a blinking manner. That is, when the rider 4 of the motorcycle 2 steps on the brake, the red lamp RL flashes on as a result, and the light emitting body 10 of the helmet 6 shown in FIG. The driver can visually confirm that the motorcycle 2 is in the initial state of υ1 from anywhere on the left or right of the front tU, and by increasing their attention to the motorcycle 2, they can prepare for the next action such as a change in course, a right turn, or a stop. This increases the safety of riding a motorcycle.

Note that the gate I7 and the transistor TR2,
Constituting the first light emitting drive circuit in the claims,
The not gate I9 and the transistor TR3 constitute a second light emitting drive circuit in the claims. Also,
The operational amplifier OP2, the charging circuit, and the oscillation circuit constitute a control circuit in the claims.

Next, the output signal of the operational amplifier OP2 becomes logic "1-"
In the case of , that is, when the driver 4 of the motorcycle 2 is driving normally without stepping on the brake, the knot gate I5
Since the output signal of is logic "11", not gate 1
6, oscillation [1] consisting of resistor R13 and capacitor C3
The four paths oscillate, and as a result, the transistor TR2 is turned on and off at regular intervals, and the green lamp GL flashes on and off. In addition, knotge 1-18, resistor R17, and capacitor C
Since the oscillation circuit consisting of 4 does not oscillate, the red lamp RL
does not light up. In the above embodiment, the light emitting body 10 is provided with the green lamp GL and the red lamp RL, but instead of the green lamp GL and red lamp RL, the light emitting body 10 is provided with a multicolor light emitting diode. The light diode A may emit green or other color T:R light during normal driving, while emitting red light when the brakes are applied.

Further, in this embodiment, an optical signal is used as a transmission medium for the brake operation signal station of the motorcycle 2, but the light emitting circuit 51
is replaced with an electromagnetic wave output circuit, the light emitter 7 and 12 are replaced with a radio wave antenna, and the photodiode PD 2 of the light receiving circuit 52 is replaced with a receiver (; i 7 antenna, high frequency amplification circuit, and detection circuit). By changing the brake operation signals of the motorcycle 2, radio waves can be used as the transmission medium.

``Effect 1 of the invention As described below-1-, according to the present invention, it is possible to
3, and during normal driving without the Play-1 operation, the illuminant attached to the helmet worn by the occupant can emit light in a color other than red, so drivers of surrounding vehicles can see it at night or on cloudy days. When visibility is poor, ``c'' can also celebrate the bike, but when operating the play ``1'', the light emitting element attached to the helmet body lights up in red, so drivers in surrounding cars can see it. It is possible to visually confirm whether a motorcycle, etc. is in the i, II vJ state from any direction, front, rear, left, or right, and by increasing attention to the motorcycle, etc., it is possible to prepare for the next action such as changing course, turning right, stopping, etc. This has the effect of making it possible to improve the safety of riding motorcycles, etc.

Historically, it has been said that driving safety can be further improved because the light emitting element can be made to flash and emit light, or the light emitting element can be made to emit light in a matter of minutes so that it can be seen even with a momentary brake operation. effective.
