Therefore, a ventilating fan motor 10 is driven by electromotive force of the solar battery SB.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic vehicle interior temperature adjustment system that suppresses an increase in vehicle interior humidity due to solar radiation.

Previously, in order to prevent abnormal rises in temperature inside the car when parked under the scorching sun, an automatic vehicle has been developed that uses solar cells as a power source to automatically operate a ventilation fan when the temperature inside the car rises above a certain level. Has a ventilation system been developed?
(Refer to Publication No. 9-57022), the increase in temperature within the city cannot be sufficiently suppressed by running ventilation fans.

〕■ The present invention has been made in consideration of the second problem, and provides an automatic vehicle interior temperature adjustment system 11 that automatically applies a sunshade to block solar radiation when the interior temperature of the vehicle exceeds a certain level. It is.

The present invention also provides an automatic vehicle temperature adjustment system that applies a sunshade when the interior temperature of the vehicle falls below a certain level and rotates a ventilation fan using a solar battery installed in the sunshade as a power source. Furthermore, the present invention provides an automatic in-vehicle degree adjustment system 11 that forcibly cancels the sunshade when the vehicle is in a running state.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, one embodiment of the present invention will be described in detail with reference to the accompanying drawings.

With the automatic vehicle temperature adjustment system according to the present invention, as shown in Figs. An actuator is attached to each so that each actuator can be electrically reversibly driven.
As shown in the figure, the output number 4m of the temperature sensor 5 that detects the temperature inside the car is read from the system controller 1 to the roll unit h6, and when the temperature inside the car exceeds a preset temperature, the output signal of the temperature sensor 5 goes to a high level. , the system controller 1 to roll unit 1-6 gives an operation command to each actuator 7 (71, 72, 7n), thereby causing each actuator 7 to move in the forward direction under the control of the system control unit 6. The sunshades are driven to lower each type of sunshade.

At that time, the system control unit 1-0 detects whether the ignition switch IGN-8W is open or not, and when the car is stopped and the ignition switch IGN-9W is opened, the detection signal becomes low level. An operation command is given to each actuator 7 only at certain times.

In addition, after an activation command is given to each actuator and each sunshade is activated, when the ignition switch IGN-'SW of the automobile is closed and its detection signal is inverted to high level, the system controller is activated accordingly. 1-
The roll units give a release command to each actuator to drive each actuator 7 in the opposite direction to perform various types of release. Furthermore, when the temperature inside the vehicle drops and the output signal of the temperature sensor 5 inverts to a low level after the various sun shades have been activated, the various sun shades are similarly canceled under the control of the system control unit 6. become.

The operation of each type of sunshade is as follows: in the case of blind 2°4, the blades are rotated from the fully open position where they are parallel to the fully open position that covers the entire window, and in the case of sunshade 3, the blades are rotated to the retracted position. It will be pulled out to a position that covers the entire surface of the sunroof. In addition, to release various types of sunshades, the blades of the blinds 2 and 4 are returned to the fully open position in a parallel state to ensure visibility, and the sunshade 3 is returned to its retracted position.

In addition, position sensors (first
(shown as a position sensor group 8 in the figure) is provided, and when each actuator 7 is driven in the forward or reverse direction under the control of the system controller 1-roll unit 6, the Control Unino 1-6
reads the detection signals of each position sensor and displays the various sunshade sections ↑
Control is such that the drive of each actuator 7 is stopped immediately when the actuator 1 reaches its operating position or release position, thereby preventing various positioning operations and over-driving of the actuator 7.

Furthermore, when the ignition switch TGN-8W is turned on, it is detected that automatic +lf lj < 4 lines is possible, but in addition to that, the engine ignition signal is also used. Can you take appropriate measures such as detecting when the automatic type is ready to drive? Further, here, the solar battery SB is used as an auxiliary power source for charging so that the on-vehicle battery BATT as the main power source does not become exhausted.

In addition, in the automatic vehicle interior temperature adjustment system according to the present invention, the solar cell SB is installed in various sunshade parts so that the solar cell SB can directly receive solar radiation during operation. Using the SB as a power source, a motor 10 of a ventilation fan 9 (see FIG. 3) provided inside the vehicle is driven under the control of a system control unit 1-6 to perform forced ventilation inside the vehicle.

That is, when the temperature sensor 5 detects that the temperature inside the vehicle has exceeded a certain level, the system control unit 1
-6 is provided in the power supply circuit of the ventilation fan motor 10, and gives an ON command to the race inochi R/SW to close its power supply circuit. At the same time, as mentioned above, the sun shades are respectively positioned in their operating positions, thereby causing each sun shade to
” Solar cells SB installed in the exposed area receive solar radiation and start generating electricity.

The ventilation fan motor 1o is driven by the electromotive force. At that time, make sure that the ventilation fan motor 1o/J is not driven by the mounted battery BATT.
~ D is provided 1, and when the temperature inside the car decreases and the output signal of the temperature sensor 5 changes to low L novel, the relay switch R-3W is opened to the system controller 1 under the control of the roll unit 1-6. The power circuit of the ventilation fan motor 10 is cut off.

Note that FIG. 3 shows a state 1P7- in which solar cells SB are installed on each blade portion of the blind 4.

In addition, the ventilation fan 9 is arranged in a direction similar to that shown in FIG.
It is provided inside the ray 11, and the high-temperature air inside the car is taken into the cabin air intake 112 of the ray 11 into the high-temperature air tank 1, and is then discharged outside the car. In addition, solar cells SB do not need to be installed in all types of sunshades,
It goes without saying that if sufficient electromotive force is obtained to drive the ventilation fan motor 10, a solar cell SB may be installed in a part of the motor. Furthermore, in that case, as the solar cell SR, for example, an amorphous solar cell formed in the form of a film together with each electrode by thin film technology may be attached to various sunshade parts.

Therefore, according to the present invention, the solar cell SB can be mounted on the vehicle body efficiently in terms of power generation, without damaging the appearance of the vehicle, and without obstructing the visibility during driving. .

As described above, in the vehicle interior temperature automatic adjustment system 11 according to the present invention, when the interior temperature of the vehicle rises abnormally due to solar radiation, various sun shades are automatically activated to block solar radiation, and if necessary, solar cells are activated. The system uses a ventilation fan as a power source to forcefully ventilate the interior of the vehicle, and when the vehicle is ready to drive, various sun shades are removed to ensure visibility when driving, such as when parking under the scorching sun. It has various excellent advantages such as being able to effectively suppress the abnormal rise in temperature inside the vehicle, ensuring vehicle running safety, and preventing the battery from being exhausted when the engine is stopped. There is.
