Description

[Detailed explanation of the invention] A. Purpose of the invention (1) Industrial application field This invention uses electric power to heat heaters installed at appropriate locations on the vehicle body in order to warm parts of the driver's body, such as the hands and feet. The present invention relates to a heater device for a vehicle.

(2) Prior Art Conventionally, in saddle-type vehicles such as buggies, a heater is attached to the throttle lever in order to warm the thumb of the driver who operates the throttle lever, and a heater is installed between the heater and the power source. It is known that a heater switch is provided to control on/off of the heater and the degree of heating.

(3) Problems to be solved by the invention However, the above-mentioned heater switch is expensive and accounts for a very large proportion of the cost of the heater device.
Further, it is troublesome to operate the heater switch to adjust the heating level of the heater in accordance with the operating condition of the vehicle.

The present invention was developed in view of the above circumstances.The existing daylight switch that controls the lighting state of the headlights is also used as a heater switch, thereby eliminating the need for a dedicated heater switch and controlling the heating level of the heater during vehicle operation. It is an object of the present invention to provide a simple and effective heater device that can be automatically adjusted depending on the state.

B. Structure of the device (1) Means for solving the problem In order to achieve the above object, the present invention consists of a main circuit connected to a power source, and an upward beam that is switchably connected to the main circuit via a day switch. In a vehicle comprising a circuit and a downward beam circuit, and an upward beam filament and a downward beam filament of a headlight are respectively inserted into the upward beam circuit and the downward beam circuit,
A strong power supply circuit and a weak power supply circuit with a higher resistance are connected to the upward beam circuit and the downward beam circuit, respectively, and a heater circuit in which a heater installed at an appropriate position on the vehicle body is inserted is connected to both power supply circuits. do.

(2) Effect When driving at high speed, if the daylight switch closes the upward heater circuit and activates the upward beam filament, the heater is energized via the strong power supply circuit. Furthermore, when the vehicle is running at low speed, if the daylight switch closes the downward beam circuit and activates the downward beam filament, the heater is energized via the weak power supply circuit. Therefore, the heating degree of the heater is automatically adjusted depending on the driving condition of the vehicle.

(3) Embodiment An embodiment of the present invention will be described below with reference to the drawings. First, in a straddle-type three-wheeled buggy vehicle 1 shown in FIG.
A headlight 3 and a steering handle 4 are attached to the upper end of the steering wheel. The steering handle 4 is a rod type with grips 4a and 4b on both left and right ends, and a headlight 3 is placed adjacent to the grip 4a on the left side.
A lighting switch 5 for turning off the light, and a daylight switch 6 for selectively operating the upward beam filament 3h and the downward beam filament 3l (Fig. 2) of the headlight 3 are provided, and are located adjacent to the grip 4b on the right side. engine 7
A throttle lever 8 that controls the output of the engine is pivotally supported. This throttle lever 8 is operated by the operator's thumb holding the grip 4b, and in order to warm the thumb, the throttle lever 8 is equipped with a heater 9.
A cover 10 with embedded therein is removably provided.

The electrical circuit of the headlight 3 and heater 9 is shown in FIG. An ignition switch 13, the lighting switch 5, and the daylight switch 6 are sequentially inserted in series from the battery 11 side into a main circuit 12 connected to a battery 11 as a power source, and first and second switching of the daylight switch 6 is performed. The upward beam filament 3h and the downward beam filament 3l are inserted into the upward beam circuit 14 and the downward beam circuit 15 extending from the contacts 6a and 6b, respectively. The downward beam filament 3l has a higher resistance than the upward beam filament 3h.

Upward beam circuit 14 and downward beam circuit 1
5, a strong power supply circuit 16 and a weak power supply circuit 17 are connected to each other via a coupler 18, and the weak power supply circuit 17 has a resistor 19 inserted therein.
The resistance is larger than that of the strong power supply circuit 16. A heater circuit 21 in which a resistor 20 and the heater 9 are inserted in series is connected to these power supply circuits 16 and 17 in common.

Next, to explain the operation of this embodiment, when driving the three-wheeled buggy 1, first close the ignition switch 13 and the lighting switch 5, and then turn the daylight switch 6 to the first switching contact 6a.
When set to the side, the upward beam circuit 14 is energized from the main circuit 12, so the headlight 3 lights up with the upward beam filament 3h.
At the same time, the heater circuit 21 is also energized from the main circuit 12 via the strong power supply circuit 16, so the heater 9 is heated with relatively large power.

Furthermore, when the daylight switch 6 is switched to the second switching contact 6b side, the main circuit 12 energizes the downward beam circuit 15, so the headlight 3 lights up using the upward beam filament 3l, and at the same time, the main circuit 12 Since the heater circuit 21 is also energized via the power supply circuit 17, the heater 9 is heated with relatively small electric power.

By the way, when driving a straddle type vehicle such as a three-wheeled buggy 1, the headlight 3 is turned on as described above regardless of whether it is daylight or not, in order to improve visibility, and when driving at high speed, the upward beam filament 3h is turned on.
Normally, when the vehicle is running at low speed, the downward beam filament 3l is activated to emit a downward beam.

Therefore, in the present invention, in order to cope with high-speed running, if the daylight switch 6 is set to the first switching contact 6a side and the upward beam filament 3h is activated, the heater 9 is automatically heated with high power. Therefore, even if the amount of heat radiated by the heater 9 is relatively large due to high-speed driving, the thumb of the operator who operates the throttle lever 8 can be effectively warmed. If the downward beam filament 3l is set to the switching contact 6b side and the downward beam filament 3l is activated, the heater 9 is automatically heated with a small amount of electric power. This means that the degree of heating of the heater 9 is adjusted, so that an appropriate temperature of the heater 9 can be ensured, and power consumption can be suppressed to the necessary minimum.

When the heater 9 is not required, such as during summer, the coupler 18 is separated and the cover 1 with the heater 9 is removed.
0 from the throttle lever 8.

C. Effects of the invention As described above, according to the invention, a strong power supply circuit and a weak power supply circuit with a higher resistance are connected to the upward beam circuit and the downward beam circuit connected to the main circuit via the daylight switch, respectively, and the vehicle body Since a heater circuit with a heater installed at the appropriate location is connected to both of these power supply circuits, the existing daylight switch can also be used as a heater switch to control the heater's on/off and heating degree. Since no switch is required, the cost of the device can be significantly reduced. Moreover, since the daylight switch is operated according to the vehicle's driving condition, the heating level of the heater is automatically adjusted accordingly, ensuring that the heater always maintains an appropriate temperature and reducing power consumption to the minimum necessary. can be suppressed to
