【０００２】[0002]
光の透過率が変化しない通常のガラスを持つ自動車の場合、晴天の駐車時に車 室内の温度が上昇し、車室内の品物に悪影響を与えるなどの問題があった。 In the case of an automobile with ordinary glass whose light transmittance does not change, there was a problem that the temperature inside the cabin rose when parking in fine weather, which adversely affected the items inside the cabin.
【０００３】 また、実開平１−３１２２１号公報によれば、図２、図３に示すように左方視 界直視窓１０のガラス１１を液晶シートで構成し、その液晶シートに左折用ウイ ンカ信号発生装置４０の左折信号に基づき通電して透過性にする制御手段（コン トロールユニット）３０を接続した車両の左方視界直視窓装置がある。なお、同 図中、５０は操舵角センサである。Further, according to Japanese Utility Model Laid-Open No. 1-31221, as shown in FIGS. 2 and 3, the glass 11 of the left-view direct-view window 10 is formed of a liquid crystal sheet, and the left-turning winker is attached to the liquid crystal sheet. There is a left-view direct-view window device for a vehicle, to which a control unit (control unit) 30 is energized to make it transparent based on a left turn signal of the signal generator 40. In the figure, 50 is a steering angle sensor.

【０００５】[0005]
本考案によれば、合わせガラスに液晶を挟持し、車両電源がＯＦＦになると液 晶に電圧を印加して、透過率を低下させる制御手段を備えている。 According to the present invention, the liquid crystal is sandwiched between laminated glasses, and a control means is provided for applying a voltage to the liquid crystal when the vehicle power supply is turned off to reduce the transmittance.
【０００６】 本考案によれば、合わせガラスに液晶を挟持し、日射量を測定するセンサと、 車内室温を測定する温度センサと、前記二つのセンサからの入力に応答して液晶 に電圧を印加する制御手段とを備え、前記制御手段は車両用電源がＯＦＦのとき のみ作動する。According to the present invention, a liquid crystal is sandwiched between laminated glass, a sensor for measuring the amount of solar radiation, a temperature sensor for measuring the room temperature in a vehicle, and a voltage is applied to the liquid crystal in response to inputs from the two sensors. And a control means for operating the control means, which operates only when the vehicle power supply is OFF.

【作用】 本考案では、合わせガラスの透過率を変化させることにより、車室内の温度上 昇を抑制することができる。According to the present invention, the temperature rise in the passenger compartment can be suppressed by changing the transmittance of the laminated glass.
【０００８】[0008]
以下、本考案の実施例を添付図面によって説明する。図１において、車室内に は日射量を測定するための太陽光センサ５と、室温センサ６が設けられていて、 いずれもコントロールユニット３に接続されている。また、図示しない運転席近 くには任意作動スイッチ７と、解除スイッチ８が並列、かつスタータスイッチ４ に直列となるように前記コントロールユニット３に接続されている。 Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In FIG. 1, a sunlight sensor 5 for measuring the amount of solar radiation and a room temperature sensor 6 are provided in the vehicle compartment, both of which are connected to the control unit 3. Further, an optional operation switch 7 and a release switch 8 are connected in parallel near the driver's seat (not shown) and in series with the starter switch 4 to the control unit 3.
【０００９】 一方、窓ガラスは中央に液晶２を挟み込んだ合わせガラス１で出来ており、液 晶２の両端は前記コントロールユニット３に接続されている。On the other hand, the window glass is made of a laminated glass 1 with a liquid crystal 2 sandwiched in the center, and both ends of the liquid crystal 2 are connected to the control unit 3.
【００１０】 そして、透過率を低下させる条件としては、前記スタータスイッチ４がＯＦＦ 状態でかつ、前記室温センサ６からの入力情報が一定温度以上の場合である。The condition for reducing the transmittance is that the starter switch 4 is in the OFF state and the input information from the room temperature sensor 6 is equal to or higher than a certain temperature.
【００１１】 また前記太陽光センサ５として、太陽電池を使用すれば、日射量の大きさに比 例して印加電圧が上げられるので日差しが強い程透過率を下げることが出来る。 したがって、室温上昇を抑制するのに効果的であるとともに、印加電圧としてバ ッテリからの電力供給が不要となり、終日こうした状態が続いても安心である。 なお、前記任意作動スイッチ７は、前記スタータスイッチ４がＯＦＦの状態で 、前記室温センサ６からの入力情報が一定温度以下の場合でも、仮眠時に使用す るカーテンの代りなどとして作動させるためものである。また、解除スイッチは 、この状態を終了させるものである。If a solar cell is used as the sunlight sensor 5, the applied voltage can be increased relative to the amount of solar radiation, so that the transmittance can be lowered as the sunlight is stronger. Therefore, it is effective in suppressing the rise in room temperature, and the power supply from the battery as the applied voltage is not required, so it is safe even if such a situation continues all day long. The optional operation switch 7 is used to operate as a substitute for the curtain used during a nap even when the input information from the room temperature sensor 6 is below a certain temperature when the starter switch 4 is OFF. is there. The release switch ends this state.
【００１２】[0012]
以上のように、本考案によると、合わせガラスの透過率を変化させることによ り、車室内の温度上昇を抑制することができる。 As described above, according to the present invention, it is possible to suppress the temperature rise in the passenger compartment by changing the transmittance of the laminated glass.
