Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle deceleration display device, and more particularly to a vehicle deceleration display device for more clearly identifying and identifying a gradual state of a vehicle brake with a large number of colors.

[0002]

2. Description of the Related Art The applicant of the present invention intends to provide a "vehicle deceleration display device", which was previously filed by the applicant, in a controller attached to an appropriate portion of a vehicle, and a guide body curved to an upside down rope and the guide body. A contactor that rolls along the inside is provided, and a plurality of switches that are turned on / off corresponding to a plurality of circuits that display different signals at certain intervals are attached to the movement path of the contactor, and
A signal display circuit is provided in series with the vehicle brake electric circuit, and the contactor is moved up and down along the inclined groove to a different range depending on the magnitude of the inertial force generated from the vehicle braking or the slow-and-fast state during deceleration. When any one of the plurality of switches is brought into contact and conducted, and the signal display circuit is controlled, the warning device attached to the rear part of the vehicle flashes different frequencies to display an appropriate signal, and the following vehicle displays the signal. Although it is configured to give a warning by notifying that the braking / braking state is slow or slow, since the applicant subsequently implemented the present invention and continuously conducted tests, the warning device of the present invention can be used, for example, as a brake indicator light of a vehicle or a first indicator. Like the brake indicator light of No. 3, it is a light emitting body that simply emits a flashing signal of a different frequency and displays a warning of different vehicle deceleration states. However, although this kind of warning display system is certainly an advance over the conventional brake status warning display by simple flashing, just like the conventional brake signal indicator, it simply emits a red light beam and displays it. Therefore, if you see a red brake signal like a current driver,
In situations where the habit of stepping on the brake immediately unconsciously tends to work, in order to determine the force to step on the brake from the speed of the mere flash frequency, it is still necessary to make a reflexive judgment and respond. If the driver is dull or easily nervous, the time required for this reaction will be prolonged, leading to driver's misjudgment and stepping on the emergency brake, and it is said that the driver or the driver of the following vehicle is driving safely. It is hard to say, and if it becomes severe, a collision accident could occur.

[0003]

When the contactor 73 blocks the light receiving unit from the light emitting unit, the light emitting diode is made to be sensitive, and its principle and function are well known to those skilled in the technical field of this type. I won't explain.

On the other hand, the warning device 8 according to the present invention is formed of two or more marking units, and in this embodiment, as shown in FIG. 3, which is a display diagram in which the warning device 8 according to the present invention is installed in a proper place of a vehicle. The warning device 8 formed of three colors, that is, the green marking unit 81, the yellow marking unit 82, and the red marking unit 83 is taken as an example to proceed with the description, and is shown in FIG. 4, which is an electric circuit diagram in the embodiment of the present invention. As described above, the plurality of sets of photoelectric switches 741 installed in the embodiment are sequentially arranged from the photoelectric switch 741 set attached to the through hole 722 near the end of the guide tube 72 screwed and fixed to the bottom cover 76. S ₁ , S ₂ , S ₃ , S ₄ , S ₅ , S ₆ , S ₇ , S ₈ ,
S ₉ , S ₁₀ ... S _n are numbered for the description. That is, among the plurality of sets of photoelectric switches 741, S _{2 to} S ₅ are combined into a G group switch, S _{6 to} S ₉ are combined into an H group switch, and S _{10 to} S _n are combined into an I group switch. , And each of the switches SW ₁ ... SW _n is connected to S ₁ ... S _n , and the switches SW ₂ ...
SW _n Different electric resistances R ₂ ... R _n are connected in series, and their resistance values are R ₂ > R ₃ > R ₄ >...> R _{n, respectively.}
To be On the other hand, the R to which the G group switch corresponds
₂ to R ₅ and connected together to a logic gate P ₁ and further the logic gate P ₁ is connected to the green indication unit 81, and R ₆ ~ the same way as the Group H switch corresponding
R _{9 is connected} to the logic gate P ₂ and R _{10 to} R _n corresponding to the I-set switch are connected to the logic gate P ₃ so that the logic gate P ₂ is connected to the yellow marking unit and the logic gate P _{3 is connected.} Is connected to the red marking unit. Then, the logic gates P ₁ , P ₂ , P ₃ are provided with capacitors C of the same value, and the electric circuit principle in which the charging / discharging time of the capacitors is proportional to the product of the electric resistance value and the storage capacity value is applied. , Increasing the electrical resistance value in the conducting circuit to increase the flashing interval time of the marking unit, conversely decreasing the electrical resistance value of the conducting circuit to shorten the flashing interval time of the marking unit, That is, the shorter the flashing interval time of the marking unit is, the higher the flashing frequency is. Therefore, the order of the flashing frequencies of the marking unit is S _n > ... S ₄ > S ₃ > S ₂ . , The flashing frequency of the green marking unit 81 controlled by the G group switch is low,
The flashing frequency of the yellow marking unit 82 controlled by the group switch is medium, and the flashing frequency of the red marking unit 83 controlled by the I group switch is the highest, so that the braking operation is rapid and the contactor 73 (in the figure, (Indicated by the one-dot chain line) shields one of the photoelectric switch sets of the I-set, the red marking unit 83 conducts and emits a high frequency red flashing warning signal, and the driver of the following vehicle responds appropriately. Take flexible action (immediately apply the brakes). If the braking operation is not so rapid, if the contactor 73 shields one of the photoelectric switch sets of the H group switches,
The yellow marking unit 82 emits a yellow flash warning signal at a moderately high frequency, prompting the driver of the following vehicle to pay attention to the braking condition of the preceding vehicle,
Have an appropriate and flexible action (moderate braking and waiting so that the legs do not leave the brake plate). Further, if the brake operation is slow, the movement span of the contactor 73 is short and any photoelectric switch of the G group switch set is shielded, so that the green marking unit 8
1 emits a green flashing warning signal with a low frequency to notify the following vehicle driver that the preceding vehicle is decelerating and instructing them to take an ad hoc operation (lightly brake without accelerating). To do. That is, this embodiment can promptly notify the following vehicle of the slow / fast state of the vehicle brake so that the vehicle can be reliably identified.

On the other hand, when the vehicle is in a state of slow deceleration or stop braking (for example, when a red traffic light is encountered and waiting for a green traffic light, or when the vehicle is temporarily stopped on a slope), that is, this brake is used. Since no inertial force is generated in this state, the contactor 73 does not move, and at this time, the photoelectric switch of the numbering S ₁ is shielded by the contactor 73, and the logic gate P ₃ advances to red color. Since the marking unit 83 is conductive and emits a non-flashing red warning signal, at the same time, since the control circuit of this embodiment is also in parallel with the conventional brake circuit, the brake light of the vehicle and the red marking unit 83 are Both emit a red warning signal, and the red marking unit 83 can be used as a third brake, which improves the practical value of the present invention.

The controller 7 is fitted and inserted into the recessed grooves 751 and 761 to hold and fix the controller 7 on the bracket 77. Then, when the controller 7 is fixed and actually tested and used, and when the contactor 73 is not sufficiently moved and shielded, the controller 7 is first removed from the bracket 777, and then the bracket 77 is removed. Loosen both bolts 91 and 92, and swing the bracket 77 to the left and right around the bolt 91 as an axis. For example, as shown by the alternate long and short dash line in FIG. 6, swing the bracket 77 to an appropriate position. If both the bolts 91 and 92 are firmly tightened again and the controller 7 is fitted to the bracket 77, the controller 7
