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 that more clearly displays the braking/sudden state of a vehicle.

0002

[Prior Art] The applicant of this invention previously filed a patent application for a ``vehicle brake warning device.'' A contactor that rolls and moves along the inclined groove is provided, and a plurality of switches that turn on and off in correspondence with a plurality of circuits displaying different signals are installed in the movement path in the groove, and a contactor that is connected in series with the vehicle brake electric circuit is installed. A signal display circuit is provided, and the contactor is moved along the inclined groove to different spans depending on the magnitude of the inertial force generated from the speed and speed of vehicle braking and deceleration, and at that time, one of the plurality of switches mentioned above is activated. One of them is brought into contact continuity, and the warning device installed at the rear of the vehicle displays a different appropriate signal under the control of the signal display circuit to notify and warn following vehicles of the slow/sudden state of the vehicle's braking. Since then, the applicant has put the invention into practice and has constantly tested it, and has discovered that there are some deficiencies in its operation. That is, since the above-mentioned inclined groove is provided inside the hollow rectangular case of the contactor means of the invention, when the contactor means of the invention is fixed to a vehicle, the angle of inclination of the inclined groove is fixed. , if the characteristics of the vehicle or the mounting position are inappropriate,
The angle of inclination of the inclined groove is not always at the best movement angle, and in this case, the contactor means must be removed and readjusted and installed, or another inclined groove with an appropriate angle of inclination may be installed. However, it is difficult to install the contactor means, and it is not applicable to all different types of vehicles, so its utility is not high.

As shown in FIG. 6, the distance between adjacent switches (17) must be larger than the diameter of the contactor (12), so that the contactor (12) is closer to the switch (17) than the contactor (12). When the contactor (12) comes into contact with one of the contactors (12), the contactor (12) is activated by contact with one of the switches (12), but when the brake is lightly applied or the speed is gradually decelerated, the relative inertial force generated is weak, that is, the distance the contactor (12) moves is shortened to the point where the switch (12) moves.
17), and therefore, the "vehicle brake warning device" of the present invention cannot display a warning sign when the brake is lightly depressed or when deceleration is gradual.

Alternatively, as shown by the dashed line in FIG. 6, if the slope of the inclined groove (10) is made gentler, the contactor (12)
If only a slight inertial force is generated, the switch may move the desired distance and contact the adjacent switch (17), but in order to cause the predetermined warning to operate based on this change alone, it is necessary to
This improvement is also by no means optimal, since the length of the force-sloping groove (10) has to be increased, thus increasing the volume of the contactor means and further increasing the difficulty of installation.

[0005]

SUMMARY OF THE INVENTION In view of the above-mentioned problems of the conventional vehicle brake warning device, the present invention is capable of displaying a clear brake status even when the brake is lightly depressed or slowing down, and It is an object of the present invention to provide a vehicle deceleration display device whose sensitivity can be adjusted appropriately.

[0006]

[Means for Solving the Problems] Therefore, in the present invention, a contactor that is movably provided along its inclined path is configured to change the resistance value of the display signal circuit to each different resistance value by inertia during braking or deceleration of the vehicle. This object is achieved by a configuration in which the display signal circuit is made to function by movably contacting one of a series of parallel switch sets connected in series with a plurality of electrical resistances indicating the display signal to close the display signal circuit.

[0007] The guide body that movably accommodates the contactor in the through hole in its hollow interior forms a curved body that curves in an inverted parapet line shape, and is arranged such that one end near the rear of the vehicle is pressed against a spring. The switch set is pivotally mounted on the upper surface of the seat body along with a spring, and its inclination angle can be adjusted by an adjusting means, and the series of switch sets are placed in the movement path of the contactor along the through hole of the guide body by rolling movement of the contactor. arranged so as to be closed, and further,
A plurality of electrical resistors each connected in series with the series of switch sets are adjusted such that the resistance value decreases sequentially in the order of the switch sets arranged from the lower end to the upper end of the contactor movement path along the through hole, and The means is formed of a threaded rod screwed onto a fixed block on the upper surface of the seat body, and an adjusting roller that can be operated by being pushed by the threaded rod that abuts and supports the lower surface of the guide body, and the means is configured to support the adjusting roller. More preferably, the inclination angle of the guide body can be adjusted by rotating the other end of the threaded rod whose tip end is fixed to the frame.

[0008]

[Operation] In the present invention constructed as described above, the contactor, which is provided so as to be movable along the inclined path, moves up the inclined path by a distance corresponding to the amount of inertia during braking of the vehicle. , a plurality of electrical resistors each exhibiting a different resistance value are moved into contact with any one of a series of parallel switch sets connected in series, and the display signal circuit is closed and operated, so that the vehicle is brought into conduction therewith. The brake indicator light can display an appropriate display depending on the speed and speed of deceleration.

[0009] Furthermore, the guide body that movably accommodates the contactor in the through hole in the hollow interior thereof forms a curved body that curves in an inverted parapet line shape, and the spring is arranged such that one end near the rear of the vehicle is pressed against the spring. The switch set is pivotally mounted on the upper surface of the seat body, and its inclination angle can be adjusted by an adjustment means, and the series of switch sets are closed by the rolling movement of the contactor in the movement path of the contactor along the through hole of the guide body. Furthermore, a plurality of electrical resistors each connected in series with the series of switch sets are arranged such that the resistance values are successively arranged in the order of the switch sets arranged from the lower end to the upper end of the contactor movement path along the through hole. In addition, the adjustment means is made up of a threaded rod screwed onto a fixed block on the upper surface of the seat body, and an adjustment roller that can be operated by being pushed by the threaded rod that abuts and supports the lower surface of the guide body. by rotationally actuating the other end of the threaded rod forming and engaging the tip of the adjusting roller with the support frame;

The above and other objects, features and advantages of the present invention will become more apparent from the following detailed description of embodiments with reference to the drawings.

By rotating the threaded rod (631) while in contact with the lower edge of the guide body (61), the inclination angle of the guide body (61) whose lower end is pressed against the spring (64) can be adjusted. do it like this.

Next, as shown in FIG. 2, the guide body (61
) are provided with contactors (62) on both sides of the through hole (611).
), a plurality of sets of light emitting diodes (70
) is provided, and the light emitting diode (
The switch set with 70) consists of a light-emitting diode emission unit (71) and a light-receiving diode reception unit (72), whose principles and functions are well known and used by those skilled in this type of technology, and are explained here. Don't explain in detail. and,
A plurality of switch sets with light emitting diodes (70), represented by symbols S1, S2, S3,...Sn, installed in this embodiment are arranged along the lower end to the upper end of the guide body (61). The contactors (62) are provided corresponding to each other at a predetermined distance apart, and are actuated by contactors (62) that are driven and generate different inertial forces depending on the braking/sudden state of the vehicle. That is, when the brake is pressed urgently, the inertial force generated in the vehicle is large, and the contactor (62) rolls and moves along the through hole (611) of the guide body (61). Reaching the top,
The light emitting diode (70) with the symbol Sn is contacted to make the circuit conductive. Based on the same logic, each contactor (62) is subjected to a different inertial force and contacts the corresponding set of light emitting diodes (70) to conduct.

Further, as shown in FIG. 3, which is a diagram showing the embodiment of the present invention installed in a vehicle, the controller (6) is installed at a suitable location in the rear trunk of the vehicle (8) or at any other suitable location. The guide body (61) of the controller (6) shown in FIG. 1 is best installed parallel to the longitudinal transmission shaft of the vehicle (8), and The highest end of the guide body (61) is connected to the vehicle (
8) should be installed close to the front end. In addition, a housing (81) equipped with a signal display circuit inside is installed at an appropriate location near the controller (6), and a conductor (8
In step 2), the controller (6) and the signal display circuit in the housing (81) are electrically connected, and on the other hand, the warning device (90) is connected to the signal display circuit in the housing (81) through a conductive wire (83). That is, the brake indicator light 9 is the warning device (90) of this embodiment, and the signal display circuit in the housing (81) is connected to the brake pedal (80) by a conductor (84).
) is electrically connected to a contact switch S0 provided at an appropriate location below the brake pedal (
When you remove your foot from the brake pedal (80),

What is shown in FIG. 4 is an electrical circuit diagram in an embodiment of the present invention, and if you also refer to the above-mentioned FIGS.
0), the contact switch S0 becomes conductive and +
A current of 12 volts is pumped. At this time, the light emitted by the light emitting diodes of the first switch set S1 is blocked by the contactor (62) as shown by the virtual dotted line in FIG. , the warning device (9
0) That is, the brake indicator light 9 indicates the ON state, and the brake state at this time indicates that the vehicle is slowly decelerating or is in a stationary state, such as when the vehicle encounters a red light at a crossroads and is waiting. Since no inertial force is generated in the contactor (62), the contactor (62) does not roll.

When the brake or deceleration of the vehicle becomes sudden, the contactor (62) rolls and moves due to the inertial force generated in the vehicle, and depending on the magnitude of the inertial force, one of the light emitting diodes (70) is activated accordingly. Kano switch set S

Each switch set S2, S3, ...Sn has a different electrical resistance R2, R3, ...Rn (R2>R3
>R4...>Rn) are connected in series, and by applying the electric circuit principle in which the charging and discharging time of capacitor C is proportional to the multiplicative product of the electric resistance value and the storage capacity value, the electric resistance value in the conductive circuit is increased. The blinking interval time of the warning device (90) may be increased, that is, the blinking frequency may be reduced, or conversely, the electrical resistance value in the conduction circuit may be decreased to shorten the blinking interval time of the warning device (90). , the blinking frequency can be increased, and therefore,
When any of the switch sets S2, S3,...Sn of the light emitting diodes (70) are turned on, the warning device (90) switches to the respective switch sets under logic control of a plurality of logic means (NAND shown in FIG. 4). S2, S3,...
A warning signal is displayed by generating different flashing frequencies in response to the conduction of Sn, and the order of high and low flashing frequencies in the warning device (90) corresponds to Sn>...>S3>S2, so , the more sudden the brake operation, the more the warning device (9)
0) is flashing violently and, conversely, if the brake operation is slow, the warning device (90) will flash slowly, or even emit light but not flash (i.e., the light emitting diode of switch set S1 will not conduct). Therefore, according to this embodiment, the braking/sudden state of the vehicle brake can be clearly displayed.

Referring again to FIG. 2, the guide body (6
Since the through hole (611) in 1) is in the shape of an inverted parapet, its initial path is relatively flat, so even the weak inertial force that occurs under light braking or deceleration will not affect the area. The contactor (62) moves along the through hole (611) and connects the light emitting diode (7) other than the switch set S1.
0), and can proceed to cause the warning device (90) to display a varying warning display. and,
The movement path of the contactor (62) gradually becomes uphill, but since a relatively sudden braking action generates a relatively large inertial force, the contactor (62)
can be rolled to a position where the light emitting diode (70) of the Sn switch set at the upper end of the through hole (611) becomes conductive, causing the warning device (90) to display the most intense warning display.

Furthermore, as shown in FIG. 5, which is a diagram showing the operation of the adjusting means of this embodiment, when adjusting the slope of the guide body (61) after the installation of the controller (6) is completed,
By turning the outwardly protruding threaded rod (631) and moving its tip forward, the adjusting ring (632) can be pushed forward, that is, the guide body (61) can be moved as shown by the dashed line in the figure. The inclination angle of the guide body (61) can be easily adjusted or modified by placing the guide body (61) on its back at a suitable slope;
The sensitivity of the rolling movement of the contactor (62) is maintained such that the expected effect occurs.

[0017]

[Effects of the Invention] In the present invention configured as described above, the contactor provided movably along the inclined path is
Since the vehicle moves up the inclined path by a distance corresponding to the amount of inertia during braking, one of a series of parallel switch sets connected in series with a plurality of electrical resistors each showing a different resistance value in the display signal circuit. Since it moves into contact with the vehicle and closes the display signal circuit to function, it has the effect of causing the vehicle brake indicator light connected thereto to display an appropriate display depending on the speed and speed of deceleration.

Further, the guide body which movably accommodates the contactor in the through hole in the hollow interior thereof forms a curved body curved in an inverted parapet line shape, and the spring is arranged such that one end near the rear of the vehicle is pressed against the spring. The switch set is pivotally mounted on the upper surface of the seat body, and its inclination angle can be adjusted by an adjustment means, and the series of switch sets are closed by the rolling movement of the contactor in the movement path of the contactor along the through hole of the guide body. Furthermore, a plurality of electrical resistors each connected in series with the series of switch sets are arranged such that the resistance values are successively arranged in the order of the switch sets arranged from the lower end to the upper end of the contactor movement path along the through hole. In addition, the adjustment means is made up of a threaded rod screwed onto a fixed block on the upper surface of the seat body, and an adjustment roller that can be operated by being pushed by the threaded rod that abuts and supports the lower surface of the guide body. If the inclination angle of the guide body can be adjusted by rotating the other end of the threaded rod, the tip of which is fixed to the support frame of the adjustment roller, it is possible to adjust the slope of the vehicle brake condition. The corresponding display will be more reliable and clear, and vehicle driving safety will be further improved.
