Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a switch mechanism for a vehicle stop signal flashing device that flashes a brake light to alert following vehicles when a traveling vehicle decelerates or stops. .

[Conventional technology]

A variety of vehicle stop signal flashing devices have been proposed in the past that flash brake lights when the vehicle decelerates or stops, but most of these devices have switch mechanisms that are turned on and off by the bias of a spring. It was configured to do this.

As a first conventional example, there is a vehicle stop signal blinking device (Fig. 9), which was invented by the present applicant and which was previously applied for utility model registration in 1981. 4 spring-loaded switches in total, 2 on the clutch pedal and 1 on the clutch pedal
It used SW1 to SW4 and had an extremely complicated configuration. In addition, switch SW1 of the accelerator pedal AP, which is biased by a spring, is configured to contact and energize as soon as you release your foot, so in the case of a gear change, immediately depress the clutch pedal CP to shut off switch SW4 and turn on the switch. It is necessary to prevent this from happening, which poses a problem in operability.Also, when using engine braking, a separate switch must be installed and the circuit must be shut off, making the circuit complicated. It had

In addition, as a second conventional example, Utility Model Application Publication No. 25887 of 1981, ``Sudden brake light lighting circuit control device for automobiles, etc.'' has been provided, but the switch mechanism in this conventional example is The structure is such that a magnetic material that rolls when a sudden brake is applied is inserted into a long guide cylinder installed in the cylinder to perform the turning.According to this structure, it operates when the brake is depressed and a sudden stop occurs, so it is difficult for the following vehicle to It was very slow to transmit signals and alert people, and it was almost impossible to prevent accidents from occurring. That is,
If you are suddenly forced to step on the brakes, you can prevent a rear-end collision by transmitting a signal to the vehicle behind you at the moment your foot leaves the accelerator pedal during the series of steps to switch from the accelerator pedal to the brake pedal. However, the switch mechanism, which operates after the brake is applied, as proposed above, slows signal transmission and is not suitable for practical use.

[Problem that the invention attempts to solve]

Therefore, the present invention was devised to eliminate the above-mentioned drawbacks of the conventional vehicle signal system.
In order to easily achieve this with one or two switches, and to transmit the signal to the following vehicle more quickly, the switch is activated instantly only when the accelerator pedal is suddenly released when sudden braking is required. The present invention provides a switch mechanism for a vehicle stop signal blinking device.

[Means for solving problems]

The present invention will be explained below based on the drawings. Figure 1a shows the accelerator lighting switch SW1 of the present invention.
(hereinafter simply referred to as accelerator lighting switch SW1)
Fig. 1b shows a perspective view of the accelerator pedal AP when it is attached to the accelerator pedal AP, and Fig. 1b shows the accelerator lighting switch.
It shows a cross-sectional view of SW1.

1 is a bottom plate made of a magnetic material such as an iron plate, and is fixed to the top surface of the accelerator pedal AP.
An upper case 2 whose tip is bent into a U-shape is pivotally attached to the bottom plate 1 by a hinge 3. Further, a permanent magnet 4 is fixed to the lower part of the inside of the U-shaped bent portion of the tip of the upper case 2, and permanent magnets 12 are fixed to the upper part of the inside. The tip of the bottom plate 1 is located between them, and when the upper case 2 moves up and down, the permanent magnet 4
and 12 are alternately attracted to the tip of the bottom plate 1. Reference numeral 6 denotes a spring provided between the bottom plate 1 and the upper case 2, and the strength of the elastic force of the spring 6 can be adjusted by means of a bolt 5 and a wing nut 13.

Reference numerals 10 and 9 denote a fixed plate and a movable plate formed on the stator 14 fixed to the bottom plate 1. When the contacts 7 and 8 provided on the fixed plate 10 and the movable plate 9 come into contact, electricity is supplied and the brake light is activated. And the pilot light is energized. Reference numeral 11 denotes a protrusion formed on the lower surface of the upper case 2 to protrude in the direction of the bottom plate 1. When the upper case 2 is pushed down, the protrusion 1
1 pushes down the movable plate 9, the contacts 7 and 8 are separated from each other, and the current is cut off.

[Effect]

The operation when the accelerator lighting switch SW1 of the present invention is attached to the accelerator pedal AP with the above configuration will be explained.

Now, when pressing down on the upper case 2 with your foot to depress the accelerator pedal AP, the spring 6
At the same time as is compressed, the protrusion 11 is also pushed downward, and as a result, the protrusion 11 pushes down the movable plate 9, and the movable contact 8 and the fixed contact 7 are separated from each other and the current supply is cut off. At this time, the permanent magnet 12 fixed to the tip of the upper case 2 comes into contact with the movable end of the bottom plate 1 and becomes attracted. Note that the spring adjustment bolt 5 and wing nut 13 are operated in advance to adjust the elastic force of the spring 6 to be slightly weaker than the attraction force of the permanent magnet 12.

When turning off the accelerator when changing gears from the state where the accelerator pedal AP is depressed, when the foot that is depressed is gently lifted, the attraction force of the permanent magnet 12 causes the spring 6 to rebound as described above. Since it is slightly stronger than the force, the permanent magnet 12 of the upper case 2 and the bottom plate 1 are held in an attracted state, and the movable contact 8 and the fixed contact 7 are maintained in a separated state and the energization is cut off.

In addition, if you quickly lift your foot from the state where the accelerator pedal AP is depressed, such as when making a sudden stop, the accelerator pedal AP will jump up and reach the upper limit, causing vibration and inertia due to the impact, and the spring The elastic force is applied, the attraction of the magnet is released, and the upper case 2 flips up, and then the permanent magnet 4 and the bottom plate 1 are attracted, and the movable contact 8 and the fixed contact 7 come into contact, energizing the brake light and the pilot light. Light.

〔Example〕

Embodiments of the present invention will be described below with reference to FIGS. 2 to 8.

FIG. 2 shows the first embodiment, and FIG. 2b shows the electric circuit. ○B is the circuit when the vehicle is driving or stopped, and the 12V power supply current does not flow because contact B of the brake lighting switch and contact A of the accelerator lighting switch are disconnected, and the current does not flow to the flicker relay F and brake light SL. And the pilot light PL does not light up.

○B indicates a state in which the foot is quickly removed from the accelerator lighting switch SW1 in order to stop suddenly, compared to the situation in ○A. As mentioned above, the upper case 2 of the accelerator lighting switch SW1 flips up, causing the accelerator to light up. Contact A of the switch is turned on, and the flicker relay F, brake light SL, and pilot light PL operate and turn on and off.

Next, as shown in the circuit shown in ○C, when the brake pedal BP is depressed, contact B of the brake pedal lighting switch (hereinafter simply referred to as the brake lighting switch)
It is also energized.

In addition, when stopping normally, if you gently release your foot from the accelerator lighting switch SW1 as shown in the circuit ○2 rather than the circuit ○a, the contact A of the accelerator lighting switch will not be energized, but the brake pedal BP will not be energized.
When the brake light switch is depressed, contact B of the brake lighting switch is turned on, causing the flicker relay F, brake light SL, and pilot light PL to flash on and off.

Next, FIG. 3 shows a second embodiment. When the power is turned on from the circuit of the flicker relay F in the first embodiment, the circuit blinks multiple times and finally remains on, when the accelerator lighting switch SW1 is turned on and the flickering relay F sends a blinking signal. If it flashes multiple times and remains lit, step on the brake pedal BP and turn the brake lighting switch SW2 on.
Since the configuration is such that the light continues to be lit without any change even if the switch is turned on, in the second embodiment, the brake light off switch SW3 is turned on immediately before the brake light switch SW2 is turned on, and the brake light is turned off once and then the brake light is turned on. The switch SW2 is turned on, and the circuit continues to turn on after giving a flashing signal several times again, and is configured to better transmit the flashing signal again to the following vehicle.

○A in Figure 3b shows the circuit when driving and when the vehicle is stopped. Contact BA of the brake light off switch is on, but contact A of the accelerator light switch and contact B of the brake light switch are off. Therefore, the fritz car relay F, brake light SL and pilot light PL
doesn't work.

○B is switch SW1 for turning on the accelerator when stopping suddenly.
This shows that the accelerator light switch contact A and the brake light switch contact BA are on, and the brake light switch contact B is off, but the flicker relay F and brake light SL are turned on.
And the pilot light PL will operate and give a blinking signal.

○C shows the case where the brake pedal BP is pressed from the state where the accelerator lighting switch contact and the brake light extinguishing switch contact BA are in the above ○b, and the subsequent operation is when the brake pedal BP is turned off. This will result in an interruption.

○D: When the brake pedal BP is continuously depressed and contact B of the brake lighting switch is turned on, the flicker relay F, brake light SL and pilot light PL are turned on again and the flashing signal is activated.

○E indicates the state when the vehicle is normally stopped.
When you release your foot from the accelerator lighting switch more slowly than in the circuit shown in ○A above, the contact A of the accelerator lighting switch remains disconnected, and when you then depress the brake pedal BP, the contact BA of the brake light extinguishing switch is disconnected. Since contact B of the brake light switch is connected from
The SL and pilot light PL are configured to operate and emit a blinking signal.

FIG. 4 shows a third embodiment. The difference from the first embodiment is that the circuit emits a flashing signal only when contact A of the accelerator lighting switch is turned on, and when contact B of the brake lighting switch is turned on later, the circuit lights only and does not flash. It is.

The circuit marked with ○A in Figure 4b is used during driving and stopping, and the contacts A and B of the accelerator and brake lighting switches.
The signal is not coming out because it is also cut off.

○B is a case where the driver quickly releases his/her foot and suddenly comes to a stop, and contact A of the accelerator lighting switch is turned on.
Flicker relay F, brake light SL, and pilot light PL are connected to emit a flashing signal.

○C continues from the state of ○B above by pressing the brake pedal.
When the BP is depressed, contact B of the brake lighting switch is turned on and the brake light SL and pilot light are turned on.
PL operates and continues to light up.

○D indicates the case where you stop by gently releasing your foot, and the contact point A of the accelerator lighting switch is
The brake pedal BP is still turned off, but the brake pedal BP
When the brake light switch is depressed, contact B of the brake lighting switch is turned on, and only the brake light SL and pilot light PL are turned on.

Next, FIG. 5 shows a fourth embodiment, which is the same circuit as the third embodiment except that the flicker relay F of the third embodiment is located on the upper side (on the opposite side).

In other words, when the circuit in ○A is running and stopped, contacts A and B of the accelerator and brake lighting switches are both disconnected, so the flicker relay F and the brake light switch are disconnected.
Both SL and pilot light PL do not work.

The circuit shown in (b) shows a situation in which the driver's foot is quickly removed, and contact A of the accelerator lighting switch is turned on, and only the brake light SL and pilot light PL are turned on and operating.

○C is when the brake pedal BP is then depressed, contact B of the brake lighting switch is turned on,
Flicker relay F, brake light SL and pilot light PL will turn on and operate.

○D is when you gently release your foot from the accelerator lighting switch SW1, so even if the contact A of the accelerator lighting switch is broken, if you press the brake pedal BP, the flicker relay F, brake light SL, and pilot light PL will operate. It is configured to emit a blinking signal.

FIG. 6 shows a fifth embodiment, which is a circuit in which the flickering signal flicker relay F of the first to fourth embodiments is removed, and the other circuits perform exactly the same operation.

FIG. 7 shows a sixth embodiment. The circles in FIG. 7b indicate when the vehicle is driving and when the vehicle is stopped, and contacts A and B of the accelerator and brake lighting switches are disconnected and do not operate.

In the case of a sudden stop, contact A of the accelerator lighting switch is turned on as shown in ○○, and the flicker relay F, pilot light PL and brake light (middle) SL1 are turned on and activated to issue a flashing signal.

Next, when the brake pedal BP is depressed as shown in ○C, contact B of the brake lighting switch is turned on, and the brake lights (left and right) SL are also activated.

When stopping normally, by gently raising your foot like ○D, contact A of the accelerator light switch is turned off, and when contact B of the brake light switch is turned on with the brake pedal BP, the brake light ( This is a two-line circuit in which only the SL (left and right) lights up.

FIG. 8 shows the seventh embodiment. As in the sixth embodiment, when contact A of the accelerator lighting switch is turned on, the flicker relay F, pilot light PL, left and right brake lights SL and middle brake light SL1 are activated. In addition to the circuits that operate together, even if contact B of the brake lighting switch is turned on, the flicker relay F, pilot light PL,
The left and right brake lights SL and the middle brake light SL1 are turned on and operated, and the rest have exactly the same configuration.

In the above configuration, the on/off contact adjustment of the accelerator lighting switch SW1 is performed by adjusting the spring 6 to the optimum elastic force using the bolt 5 and the wing nut 13 as described above. In addition, in this invention, when the accelerator lighting switch contact A and the brake lighting switch contact B are on during a sudden stop, the key K is pressed to stop the engine.
Even if the switch is turned off, the engine will not stop unless contact B of the brake lighting switch is turned off due to the reverse current circuit from contact B of the brake lighting switch.
Diode D cuts off the reverse current circuit, and the engine is configured to stop even if contact B of the brake lighting switch is closed.

[Effect of idea]

As explained above, the switch mechanism of the vehicle stop signal flashing device of the present invention has the following effects.

When the accelerator lighting switch is pressed down on the movable plate by the protrusion when the accelerator is depressed, the power to the switch is cut off, and if the foot that has been depressed is gently released from this state, the permanent magnet 1
2 and the bottom plate 1, the switch is held in the off state by suction, so the switch does not turn on automatically due to vibrations on rough roads, and when using the engine brake, changing gears, or decelerating. Even in this case, the switch is not energized and does not generate a signal, which has the effect of not causing unnecessary attention to the driver of the following vehicle.

When stopping suddenly, such as when an obstacle suddenly appears, if you quickly release your foot from the accelerator lighting switch, the accelerator pedal will jump up and reach its upper limit, which will cause vibrations and inertia due to the impact, as well as the elasticity of the spring. When power is applied, the upper case flips up and the lighting switch is energized, so in addition to the conventional configuration of turning on the light by depressing the brake pedal, in an emergency, the light flashes repeatedly multiple times and lights up to quickly alert the following vehicle. By calling the driver's attention, it is possible to eliminate rear-end collisions.

By using the conventional brake light switch installed in vehicles as is and incorporating only one accelerator light switch of this invention, the purpose can be completely achieved, and the structure is simple and easy to manufacture. It has the advantage of being inexpensive.

If the circuit of the present invention is used in addition to the conventional brake light switch circuit, even if a failure occurs in the switch or circuit of the present invention, braking will be performed by the circuit of only the brake light switch. Since the light is configured to turn on, it has the effect of extremely high safety.
