Abstract

PROBLEM TO BE SOLVED: To reduce power consumption and increase the attention level via blinking by using a delayed oscillating circuit or a flip-flop circuit for blinking a headlight or a marker lamp as a basic circuit, and blinking a light emission diode. SOLUTION: A blinking/lighting circuit not affected by the noise of a motor via the existence of a capacitor (e) is provided with a base resistor (a) and a capacitor (b) for the time constant determining the blinking interval, NPN and PNP type switching transistors Tr 1, Tr 2 constituting a blinking circuit, a light emission diode (d) connected as a load, and the noise absorbing capacitor (e). When the base resistor (a) is made a variable type or a fixed type, the blinking/lighting circuit is made a variable type or a fixed type. Since this blinking/lighting circuit is thus constituted, the power consumption can be reduced when a headlight or a marker lamp is lighted.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mini four-wheel drive vehicle for a model that runs on a battery, and makes the mini-wheel drive vehicle closer to the feeling of an actual four-wheel drive vehicle or a running vehicle. It is designed to be more fun to play. In more detail, an issuance diode is attached to a mini four-wheel drive vehicle to make it appear as if the headlights and indicator lights of the electric system are turned on or that the flame is being injected from the muffler of the fuel exhaust system.

[0002]

2. Description of the Related Art A conventional mini four-wheel drive vehicle for a model is a scale model vehicle and at the same time competes for running by using a battery. Therefore, a driving mechanism, in particular, a motor and a driving gear are used. I was impressed by the mechanism, and the other parts had no secondary feeling. In particular, in a circuit related to an electric system, it is hardly conceivable to attach another circuit from the viewpoint of power consumption and the like, because it leads to a rapid consumption of the battery and an increase in the weight of the entire vehicle. Therefore, from the viewpoint of play, the running of the mini four-wheel drive vehicle as a model did not feel any shortage.

[0003]

Therefore, the present applicant has utilized recent electronic components, which are extremely miniaturized, are lightweight and have low power consumption, and use them for headlights of mini four-wheel drive vehicles. It is intended to bring the interest as a toy closer to reality and to make the game more enjoyable and more realistic. As mentioned above, the mini four-wheel drive vehicles currently available on the market for models are scale model vehicles that are modeled on actual racing vehicles, etc., whose shape is difficult to change and a battery-driven motor is used. Since the battery is used, the amount of power consumed by the battery has become a significant factor related to the speed of the running vehicle. Therefore, at present, it is necessary to avoid mounting a device that quickly exhausts the battery. However, recent batteries have been gradually improving their performance and have appeared to be rechargeable, so that a slight increase in power consumption has a sufficient capacity to accept it, and the capacity has also increased. If the electrical load is very small, it is in a state where mounting is possible. Also, recent electronic components are very small and lightweight, so that they can be mounted without changing the appearance of the model and without significantly increasing battery consumption, if there is only a small space. Therefore, the applicant has succeeded in creating a more realistic toy with more realistic feeling by using the small electronic components to turn on the headlights and turn on the marker lights.

[0004]

As shown above, the current consumption of a mini-bulb using a general filament for lighting the headlights, marker lights, etc. of a mini four-wheel drive model car is of course large. The electronic components considered there are light-emitting diodes.Currently, light-emitting diodes are not only bright but also consume a few tens of milliamps, and their size is very small. It is just the right part to use. In addition, recently, even high-brightness ones have appeared, so that when they are attached to toys, they have enough elements to attract attention from the surroundings.
In addition, there are some difficulties to completely resemble the real thing with red, green and yellow colors, but when used as a toy, the effect can be fully exhibited. Therefore, if these electronic components are used to turn on the headlights or turn on the artificial marker lights, the game becomes more enjoyable and the game becomes more realistic. Further, when the light emission of the light emitting diode is intermittently lighted, the effect of remarkable attention from the surroundings can be more effectively extracted, and at the same time, the power consumption of the light emitting diode is reduced.

[0005]

Example The first example is

The implementation of what is shown in claim 1.

As shown in FIG. 1A, a light emitting diode (a) is used for a headlight (2), a marker light, etc. (not shown for the sake of description) of a mini four-wheel drive vehicle (1) for a model. It is installed by selecting the color and size according to the application. The meaning that the light emitting diode (a) is selected according to the purpose or application means that the emitting diode (a) has red, green, yellow, etc. types, so that the colors can be freely selected. This is because the target object is a toy, and a color different from a practical one can be selected. Therefore, if the emphasis is on the actual scale model, the color and size of the LED should be close to the actual one, and if you expect the luminous effect and the degree of attention, the power consumption, size or color is your preference. If a light emitting diode with high luminance and slightly higher power consumption is used, considerable attention can be expected. The function and effect is that a newly attached light-emitting object can considerably increase the attention from the surroundings, and has a great effect of enjoying a highly realistic game close to actual running.

FIG. 1B is an electric circuit diagram including a battery (e) and a motor (f) when the light emitting diode (a) is turned on. In the figure, (a) is a light emitting diode (c) and a surge absorbing capacitor. FIG. 2B shows a resistor for adjusting brightness. Parts (b) and (c) in the figure are parts that can be omitted depending on the use situation. (E) shows the battery (f) shows the motor.

[0006] The second embodiment is

(2) In implementing the present invention, the appearance is not different from that of the first embodiment.

FIG. 1 is exactly the same. However, the implementation requires an electric circuit for intermittently lighting the light emitting diode (a). Therefore

FIG. 2 shows this electric circuit.

FIG. 2A is an intermittent lighting circuit using a flip-flop circuit;

FIG. 2B is an intermittent lighting circuit using a delay circuit.

FIG. 2A

FIG. 2B is not a completely new electric circuit

FIG. 2A shows a flip-flop oscillation circuit in which a light emitting diode (a) is used in a load resistance portion;

FIG. 2B is a diagram in which a light emitting diode (a) is used for a load resistance portion of a delay oscillation circuit, and in any circuit, when the resistance value shown in (b) and the capacitor value shown in (c) are appropriately changed. If the constants are properly selected, an intermittent lighting circuit can be obtained at any time interval. The transistor shown in (d) is a general switching transistor represented by NPN or PNP. Although the above-described electric circuit and the blinking circuit using the light emitting diode are experimentally present, it is considered that there are few examples in which the circuit is applied to a headlight of a toy automobile. It is considered that there is no example of using a mini four-wheel drive vehicle for toys. As an effect, even if the light emitting diode is turned on intermittently, the appearance is

[Fig. 1] Although it is no different from the above, by turning on the light emitting diode intermittently, the degree of surrounding people's attention to this mini four-wheel drive vehicle increases, and it is much more satisfying to play if the surrounding people's attention is gathered more The degree increases and it becomes interesting. Also, since the electronic components for constituting such a circuit are all relatively easily and inexpensively available, they can be easily mounted if there is some space in a part of the mini four-wheel drive vehicle.

A third embodiment is

As shown in FIG.

A light emitting diode (a) is mounted on, for example, an exhaust pipe (3), which is different from the first embodiment and the second embodiment and has no relation to lighting in practice. It aims at a virtual effect as if a red flame is blowing out from the exhaust pipe (3). The purpose of the present embodiment is to attach the light emitting diode (a) to a place having little relation to the actual lighting effect to gather surrounding interest and aim at the attention effect. The sign lamps and the like which have not been specifically described in the above are examples thereof. The sign lamps include a blinking lamp of an ambulance in addition to a tail lamp and the like. However, this embodiment focuses on the exhaust pipe having the greatest effect among them, and focuses on the light emitting diode (a).
The aim is to attach a red flame to the exhaust pipe. The light emitting diode to be mounted may be turned on continuously, but intermittent lighting is more effective in consideration of the degree of effect. The color is generally red, but other colors may be used. The operation and effect are similar to those of the first and second embodiments, and the effect is large.

[0008]

The feature of the invention of the present application is that a luminous body is newly attached to a conventional mini four-wheel drive vehicle, whereby a realistic and realistic feeling close to the actual running can be expected, and at the same time, from the surroundings, The effect of attracting interest is also enormous, the competition is more fulfilling and fun, and the effect is great.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is applicable to a model four-wheel drive vehicle driven by a battery, for example, a mini four-wheel drive vehicle or a remote control four-wheel drive vehicle. This model is designed to make the vehicle more similar to that of a traveling vehicle and to play a model four-wheel drive vehicle more enjoyably. For more details, the issuance diode is attached to the above mini four-wheel drive vehicle or the model four-wheel drive vehicle for remote control, and it is lit or flashing as if the headlights and marker lights of the electric system are lit or flashing or the fuel exhaust system The aim is to make the four-wheel drive vehicle travel as if it were closer to the actual condition by allowing the muffler to run as if the flame were actually being injected. Above all, for the simulated light emission that travels by blowing fire from a muffler, the blinking and lighting of the light emitting diode is an essential condition.

[0002]

2. Description of the Related Art Conventionally, this kind of model four-wheel drive vehicle is driven by a battery, and since it is a scale model vehicle, its external shape and design cannot be changed so much. I was particularly impressed with the motor and the gear mechanism for driving, and the other parts were without a secondary feeling. Especially in the circuits related to the electric system, batteries are used, so from the viewpoint of power consumption etc., it is hardly conceivable to install other extra circuits because it leads to the rapid consumption of the batteries and the increase in the weight of the entire vehicle. It was not possible. Therefore, when looking at the running of the four-wheel drive vehicle as a model from the aspect of play, there were many times when a slight lack was felt.

[0003]

Therefore, the present applicant has proposed that the recent electronic components are becoming very small in size, light in weight and very low in power consumption. It is considered that the interest as a toy can be more actually approached and the game can be made more enjoyable if it is lit or blinked for use. However, as a result of various investigations, it has been found that a light emitting diode which is continuously lit at the present time already exists. Therefore, the light emitting diode is turned on and off to thereby reduce the power consumption, and at the same time, the attention degree is increased by the blinking and the effect is enhanced. However, there are some problems for a model four-wheel drive vehicle to blink a light emitting diode at an appropriate interval. That's because four-wheel drive vehicles use a DC motor to drive, so the noise will cause the blinking to be disturbed and not blink as expected. Thus, the present invention has succeeded in eliminating this problem and at the same time allows the blinking interval to be appropriately varied.

[0004]

As shown above, it has become common sense to use light emitting diodes to light the headlights, marker lights, and the like of a model four-wheel drive vehicle.
However, it is easy to imagine blinking the emitting diode as an idea, but when you actually execute it, it blinks and lights at the desired light emission interval as disturbed by the noise of the DC motor as described above The fact is that it doesn't work. Therefore, it is conceivable to insert a capacitor for noise removal, but it is not possible to insert a capacitor at a very easy point, because the energy due to the noise of the motor is large and the noise is easily removed. This is because the time constant of the electronic component is disturbed when a capacitor is inserted in an arbitrary location, and an appropriate blinking interval cannot be obtained. In order to eliminate noise that disturbs the blinking interval, we attempted to insert capacitors in various places.As a result, we inserted a capacitor for noise removal in parallel with the resistor that determines the time constant, that is, the base resistor. The mounting location is not limited to parallel with the time constant resistor, but is mounted in parallel with the light emitting diode as a load, thereby directly removing noise received by the light emitting diode. As a result, the noise of the motor is removed, and at the same time, the electric charge charged at that time is discharged in reverse when the light emitting diode is turned on, and the lighting of the light emitting diode is more effectively used. As a result, the blinking of the light emitting diode could be turned on and off with almost no influence from the noise of the motor. In addition, this time, a delay oscillation circuit and a flip-flop circuit were used as one means of blinking and lighting the light emitting diode.However, in order to adjust the blinking interval in the flip-flop circuit in this, change the time constant of these base resistors. It is a general means to adjust, but in the present invention, in contrast, the present invention is not limited to this, and one of the flip-flop circuits is a circuit dedicated to adjusting the blinking interval, and the load resistance portion of this circuit is changed. By making it variable, the blinking interval was successfully changed. Such a variable circuit has a feature that it is hardly affected by motor noise because a large current flows through the variable portion.

[0005]

【Example】

FIG. 1 and

[Fig. 2]

[Fig. 1]

Next,

FIG. 2 is a blinking lighting circuit of a light emitting diode using a flip-flop circuit.

FIG. 1 is substantially the same as that shown in FIG. 1, but differs from the first embodiment in that the transistor in (c) requires only one type of NPN and the number of parts is slightly increased because the entire circuit is a flip-flop circuit. . Therefore, in this circuit, the same action can be obtained even if the direction of current flow is reversed by using a PNP transistor. The feature of this circuit is that when one of the light emitting diodes (d) is on, the other light emitting diode (d) is off, so that the current consumption can be further reduced as a whole. In such a circuit, the current flowing through the base resistor in (a) is

As in the case of FIG. 1, the capacitor is small and easily affected by motor noise. To avoid this, a noise absorbing capacitor (e ') is inserted in parallel with the base resistor of (a). However, it has been confirmed by experiments that this capacitor does not need to be inserted at two places even though the base resistance (a) has two circuits, and the effect is exhibited only on one side. Therefore, it is sufficient that one capacitor (e ') is provided in parallel with either the left or right base resistor. Also, to completely absorb this noise

FIG. 1 shows that the effect is further increased by inserting a capacitor (e) in parallel with the light emitting diode (d) as in the case of FIG. 1, but also at this time only one of the two light emitting diodes (d) is inserted. Is enough. Therefore, the present invention also features such contents. However, if space allows, it can be included in both.

[0007]

FIG. 3 shows a light emitting diode for lighting and blinking.

FIG. 2 is the same as one side of a flip-flop circuit for blinking and lighting a light emitting diode shown by. However, two light emitting diodes (d) are connected in parallel on the load side.

FIG. 2 is different from FIG. Moreover, in this embodiment, the other side of the flip-flop circuit includes the base resistor (a), the charge capacitor (b), and the transistor (c).

FIG. 2 is similar to the circuit of FIG. 2, except that a load resistance (f) is connected to a place where the light emitting diode (d) is connected.
That is, one side of the flip-flop circuit is used for a blinking lighting circuit, and the other side is used for a time constant circuit that determines a blinking interval.

FIG. 2 is different from the case of FIG. Therefore, if the load resistance in (f) is variable, the blinking interval of the light emitting diode in (d) changes continuously, and if the load resistance (f) is fixed, the blinking interval is fixed. This embodiment is significantly different from the other embodiments in that one side of the flip-flop circuit is a circuit dedicated to a time constant for determining the time of blinking and lighting of the light emitting diode. Therefore, it is necessary to insert a noise absorbing capacitor (e ') in parallel with the base resistor (a) or the light emitting diode (d) in order to remove the noise of the DC motor.

FIG. 2 is the same as the case shown in FIG. 2, but in this embodiment, a noise absorbing capacitor (e) is inserted in parallel with the load resistor (f) to absorb noise. The feature in this case is that the capacitor (e ') is inserted in parallel with the light emitting diode (d), and a smaller capacitor is required, and is much more affected by noise than when the capacitor is inserted in parallel with the base resistor (a). Has difficult features. Therefore, the capacitors (e) and (e ') for absorbing noise may be put in place according to the purpose. The feature of this whole circuit is to adjust the blinking of the light emitting diode on one side of the flip-flop circuit, so the current of the whole circuit will be slightly larger, but it is very strong against surge current caused by motor noise and also for time constant determination Has a characteristic that the variable resistor can take a relatively free value.

[0008]

[Effects]

[Fig. 1]

FIG. 3 summarizes the functions and effects described above. All of these circuits need to be accommodated inside the body of a narrow model without affecting the appearance of the model as much as possible. Therefore, it is required that the number of electronic components to be used is small or small, and it is ideal that it is not affected at all by the noise of motors, etc. I can say that. This application was first filed on May 2, 1997 as a "mini four-wheel drive model car with light-emitting circuit" as an application of a light-emitting diode to a mini four-wheel car car for models. It is known that there is already an application of a diode to a model four-wheeled vehicle, so this is changed and only the lighting and blinking circuit therein is applied as a feature thereof. Since the lighting and blinking circuit does not blink as desired due to the noise of the motor as it is, a noise removing circuit for removing the noise in the circuit is also to be filed at the same time. This allows the model four-wheel drive vehicle to attract more attention and enjoy powerful driving regardless of whether it is a mini four-wheel drive vehicle or a remote control four-wheel drive vehicle .
