201027071 六、發明說明： 【發明所屬之技術領域】 本發明關於一種開閉式窗玻璃破損檢測裝置。 【先前技術】 專利文獻1係揭露一種爲了防範竊盜而用以檢測車輛 之窗玻璃破損的裝置。該裝置如第23圖所示，具備有壓縮 螺旋彈簧220，其係在當窗玻璃200位於封閉窗開口部之 完全關閉位置時，將支撐該窗玻璃200的纜線式窗調節器 © 210之承載板211推往窗玻璃200之關閉方向。當窗玻璃 200破損時，設置於窗玻璃200的停止銷205與車體側之 卡止部206的卡止限制被解除，壓縮螺旋彈簧220使承載 板2 1 1朝關閉側移動超過窗玻璃200之完全關閉位置。極 限開關23 0感測到承載板2 1 1之移動並檢測出窗玻璃200 的破損。 專利文獻：日本特開平1 1 -3 2 1 5 64號公報。 【發明內容】 〇 由於前述裝置係檢測窗玻璃200是否朝向關閉側而移 動超過完全關閉位置的構成，因此當窗玻璃200未處在完 全關閉之位置處，即，爲了換氣而將窗玻璃200稍微開啓 之狀態下，係無法檢測出窗玻璃200的破損。 本發明之目的係提供一種即便窗玻璃不是位於全閉位 置時亦可檢測窗玻璃之破損的開閉式窗玻璃破損檢測裝 置。 爲了達成前述目的，依據本發明第1態樣之窗玻璃破 損檢測裝置，係具備有：磁石；磁性檢測部；判斷部；以 201027071 及芯材。該磁石係產生固定之磁場，且設置在能自由開閉 車輛之開口部的窗玻璃處。該磁性檢測部係檢測出該磁石 所產生的磁場。該判斷部係根據該磁性檢測部所檢出的磁 場來檢測出窗玻璃之破損；該芯材由磁性材料所組成，且 與磁性檢測器呈磁氣結合，並至少具有沿上下方向延伸的 立設部。 依前述構成，藉由磁性檢測部來檢測出設置在（能自由 開閉車輛之開口部）窗玻璃的磁石所產生的磁場，並在判斷 〇 部根據該磁性檢測部所檢出的磁場來檢測出窗玻璃之破 損。 此處，與磁性檢測器呈磁氣結合之由磁性材料所組成 的芯材，係至少具有沿上下方向延伸的立設部，因此即使 窗玻璃不是位於全閉位置時亦可通過該芯材而將磁石之磁 力傳達給磁性檢測器，以藉由磁性檢測部來檢測出該磁石 所產生的磁場。藉此，可檢測出窗玻璃之破損。 較佳爲，該判斷部係根據該磁性檢測部所檢出的磁場 Q 來檢測出伴隨窗玻璃之破損所造成之磁石掉落。 依前述構成，藉由磁性檢測部來檢測出被設置在能自 由開閉車輛之開口部的窗玻璃處的磁石所產生的磁場，並 使用判斷部來根據該磁性檢測部所檢出的磁場來檢測出因 窗玻璃之破損所造成之磁石掉落。 依據本發明第2態樣之窗玻璃破損檢測裝置，係具備 有：磁石；磁性開關；相反磁場產生用線圈；判斷部；以 及芯材。該磁石，係產生固定之磁場，且設置在能自由開 閉車輛之開口部的窗玻璃處；該磁性開關，係依該磁石所 201027071 產生的磁場而開啓；該相反磁場產生用線圈，係連接至該 磁性開關，伴隨該磁性開關之開啓，產生相反磁場以抵消 該磁石的磁場，進而關閉該磁性開關；該判斷部，係根據 該磁性開關的切換周期來檢測出窗玻璃之破損；以及該芯 材，由磁性材料所組成，係與磁性檢測器呈磁氣結合，纏 繞有該相反磁場產生用線圈，且至少具有沿上下方向延伸 的立設部。 依前述構成，依設置在能自由開閉車輛之開口部的窗 〇 玻璃處之磁石所產生的磁場來開啓磁性開關，伴隨磁性開 關之開啓，在相反磁場產生用線圈產生抵消該磁石之磁場 的相反磁場，進而關閉該磁性開關。接著，根據該磁性開 關的切換周期來檢測出窗玻璃之破損。 此處，與磁性開關呈磁性結合且纏繞有相反磁場產生 用線圏之由磁性材料所組成的該芯材，係至少具有沿上下 方向延伸的立設部，因此即使窗玻璃不是位於全閉位置時 亦可通過該芯材將磁石之磁力傳達給磁性開關，且能有效 U 率地賦予相反磁場產生作用，藉以檢測出窗玻璃之破損。 較佳爲，該判斷部係根據該磁性開關的切換周期來檢 測出因窗玻璃之破損所造成之磁石掉落。 依前述構成，磁性開關係依被設置在能自由開閉車輛 之開口部的窗玻璃處之磁石所產生的磁場而開啓，伴隨磁 性開關之開啓，於相反磁場產生用線圈產生抵消該磁石之 磁場的相反磁場，進而關閉該磁性開關。接著，使用判斷 部來根據該磁性開關的切換周期來檢測出伴隨窗玻璃之破 損所造成之磁石掉落。 201027071 此處，與磁性開關呈磁性結合且纏繞有該相反磁場產 生用線圈之由磁性材料所組成的該芯材，係至少具有沿上 下方向延伸的立設部，因此即使窗玻璃不是位於全閉位置 時亦可通過該芯材將磁石之磁力傳達給磁性開關，且能有 效率地賦予相反磁場，藉以檢測出窗玻璃之破損。 較佳爲，該芯材係由高透磁率材料所組成。 較佳爲，於該窗玻璃之端部更具備有用以夾持窗玻璃 的夾具，且該磁石係固定於該夾具處。 〇 較佳爲，該夾具含有第1構件與第2構件，在該窗玻 璃設置於該第1構件與該第2構件之間的狀態下，該等構 件係於該窗玻璃之面內相互交錯的位置處接觸該窗玻璃， 並且朝相互接近的方向施加其本身的彈力》 【實施方式】 (第1實施形態） 以下，根據圖式來說明將本發明具體化之第1實施形 態。 Φ 第1圖係客用車之右前方車門的立體系統圖，第2圖 係客用車之右前方車門的槪略前視圖。 如第1圖所示，車門1係具備有外側壁板2與內側壁 板3。於外側壁板2與內側壁板3之間係設置由強化玻璃 作成的窗玻璃5。窗玻璃5之厚度爲3 .lmm〜5 mm左右。車 門1之內側壁板3的內側安裝有車門內裝8(trim)。 車門1之內部係收納有讓窗玻璃5朝上下移動的窗調 節器10。本實施形態係使用X型臂式窗調節器來作爲該窗 調節器10。於內側壁板3貫穿設置車門零件安裝開口 3a, -6- 201027071 並以封閉該車門零件安裝開口 3 a的方式設置模組化壁板 6 〇 X型臂式窗調節器1〇係藉由基座（固定座）而支撐於該 模組化壁板6的室外側之面。即，固定在模組化壁板6的 室外側之面處的基座U係支撐有X型臂式窗調節器1〇之 昇降臂12的軸13。基板11係固定有電力驅動單元14。該 昇降臂12與第2圖所示以軸13爲中心的扇形齒輪（從動齒 輪）15形成一體，第1圖之電力驅動單元14係具備了與該 © 扇形齒輪相嚼合的小齒輪16(第2圖）以及其驅動馬達（圖中 未顯示）。 第2圖中，藉由軸17將平衡臂18之中間部份樞接於 昇降臂12之長度方向的中間部位處。昇降手臂12與平衡 臂18之上端部（前端部）係各自樞接有（可旋轉及傾斜移動） 導引件（轉子）19、20，且平衡臂18之下端部係樞接有導引 件（轉子）21。 該昇降臂12之導引件19與平衡臂18之導引件20係 @ 可自由移動地嵌合於窗玻璃托架22，平衡臂18之導引件 2 1係可自由移動地在固定於第1圖之模組化壁板6室外側 之面的上平衡臂托架23(姿勢維持軌道）上被導引。 另一方面，在窗玻璃5之下緣，於前後方向處固定有 窗玻璃支撐座24。該窗玻璃支撐座24係預先固定於窗玻 璃5之下緣處，具有該窗玻璃支撐座24的窗玻璃5由外側 壁板2與內側壁板3之間隙處插入，支撐座24利用螺栓 25固定於窗玻璃托架22 » 如第2圖所示，於前後立設有一對之玻璃導軌2 6。該 201027071 玻璃導軌26係由橡膠所製成。藉由作爲導軌構件之該前後 一對之玻璃導軌26，以可自由移動的方式來支撐窗玻璃 5。即，形成爲窗玻璃5之前後端部由玻璃導軌26所導引 而可進行上下移動。 使用第1圖之電力驅動單元14使小齒輪16朝正、反 方向驅動時，昇降臂12係藉由扇形齒輪15以軸13爲中心 作搖動，其結果，藉由平衡臂18、導引件19、20、21及 平衡臂托架23，使得窗玻璃托架22保持約略水平的狀態 © 下進行昇降運動。如此一來，窗玻璃5被昇降，車輛之開 口部4依窗玻璃5而自由開關。 第2圖中3 - 3線之縱剖面圖係如第3圖所示。第3圖 中，預防不法侵入用的開閉式窗玻璃破損檢測裝置3 0係設 置於車門1之內部。破損檢測裝置30係具有夾具40、磁 石50、檢測部60、判斷部70以及警報部80。 第4圖係開閉式窗玻璃破損檢測裝置30的立體圖。第 5圖中（a)、（b)係顯示開閉式窗玻璃破損檢測裝置30，（a) φ 係前視圖，（b)係（a)中5b-5b線的縱剖面圖。 第3圖中，外側壁板2與內側壁板3之間係設置有窗 玻璃5，並藉由防水膠條7來保持密封狀態。又，內側壁 板3的內側係設置有車門內裝8。夾具40係設置於窗玻璃 5之下端部，並藉以夾持該窗玻璃5。 如第5圖所示，夾具40係彎折一片板彈簧用鋼板所構 成的。夾具40係具有對向設置的第1及第2構件41與42、 以及彎折部43(連結部）。背面側之第1構件41係形成長方 形，正面側之第2構件則形成寬度較第1構件41更狹窄的 201027071 正方形。背面側的第1構件41與正面側的第2構件之間係 設置有窗玻璃5，且第1構件41與第2構件係朝相互接近 的方向對窗玻璃5施加彈力。 彎折部43係連結第1構件41與第2構件。該彎折部 43係彎折成2層，第2層之彎折部43b的寬度較窗玻璃5 之厚度更窄，而第1層之彎折部43a係接觸窗玻璃5之端 面。 第5圖中，於第1構件41之中央部係形成有長方形的 φ 開口 44。第2構件係位於對應該開口 44的位置。如第5 圖（a)所示，對應於第1構件41之開口 44的內部處，第2 構件42如第5圖（b)所示係接觸窗玻璃5之另一面（表面 5a)。且第2構件42係接著於窗玻璃5上。 如此一來，設置有窗玻璃5的第1構件41與第2構件 之間，於窗玻璃5之面內，第1構件41與第2構件42係 於相互偏離的位置處接觸至窗玻璃5，並朝向相互接近的 方向施加彈力。即，於窗玻璃5之表面5a與內面5b的不 φ 同位置處，對窗玻璃5施加一力量。又，夾具40係大於特 定之力量（以上）夾持（把持）窗玻璃5之下端部。 如第4圖、第5圖所示，夾具40之第2構件42的前 面側固定有磁石50(永久磁石）。本實施形態係使用肥粒鐵 磁石作爲磁石50。如第4圖所示，將磁石50磁化成左半 部爲N極而右半部爲S極。作爲磁場產生部之磁石50係產 生如第4圖所示之固定磁場Η 1。 如第3圖所示，檢測部60係固定於內側壁板3。此處， 將鉛直方向定義爲X方向，且水平方向定義爲Υ方向。當 201027071 夾具40朝X方向移動時，即代表其落下。 第6圖係顯示磁石50與檢測部60之磁性檢測器61的 位置關係圖。 如第4圖、第6圖所示，檢測部6 0係具備有用以檢測 磁石50所產生之磁場H1用的磁性檢測器61、以及設置於 該磁性檢測器61左右側的芯材62a與62b。芯材62a、62b 係由磁性材料所組成。具體而言，芯材62a、62b係由高透 磁率的高導磁鎳鋼（permalloy)所組成。芯材62a、62b係各 〇 自由1根棍材所形成，且係由朝上下方向延伸的立設部 63、以及從該立設部63下端朝水平方向呈L字形延伸的水 平部63所構成。芯材62a、62b之立設部63的上端部係設 置於與窗玻璃5全閉時之磁石50幾乎相等高度的位置（相 對磁石50於Y方向上相距特定距離）。又，磁性檢測器61 係設置於靠近芯材62a、62b水平部64的前端面。藉此， 使作爲磁性檢測部之磁性檢測器6 1係與芯材62a、62b呈 磁性結合，且，芯材62a、62b之一部份係朝上下方向延伸。 @ 磁石50之磁場（磁力）依芯材62a、62b而集中並傳達給磁 性檢測器6 1，可提高磁性檢測器6 1之磁通密度。 磁性檢測器6 1輸出因應於磁場（磁性強度）的訊號。如 第3圖所示，磁性檢測器6 1係連接至判斷部70。判斷部 70係具備有A/D轉換器與微電腦，微電腦可接收來自磁性 檢測器61且經過A/D轉換後的訊號。又，芯材62a、62b 係具備有朝上下方向延伸的立設部63，因此，相較於無芯 材之情況下的Vs2(參考第7圖），可廣範圍地提高磁性檢測 器61之輸出Vsl(參考第7圖）。其結果，可於廣範圍地檢 -10- 201027071 測出磁石5 0的位置。即，如第8圖所示，當窗玻璃未在全 閉位置處而是爲了換氣而稍微開啓窗玻璃時，會使得磁石 50位於稍低位置處，但於此情況下亦可獲得高輸出準位的 訊號。 然後，第3圖之判斷部7 0係根據磁性檢測器6 1所檢 測出的磁場，即，根據檢測器輸出（Vs 1 )來檢測出伴隨窗玻 璃之破損所造成之磁石50掉落。第3圖中，判斷部70係 連接至警報部80。 〇 其次，說明如此構成之開閉式窗玻璃破損檢測裝置的 功用，即，說明當窗玻璃5損壞（龜裂）時的作動。 通常，當乘客離開車輛時窗玻璃5係位於全閉或稍微 開啓之狀態。判斷部70會從（第7圖）檢測器輸出準位（Vs 1) 來檢測出窗玻璃5的位置，當操作手煞車時窗玻璃5是位 於全閉或稍微開啓之狀態，則設定爲玻璃破損檢測模式。 另一方面，如第5圖所示，設置於窗玻璃5之端部的夾具 40係夾持著窗玻璃5的端部。詳言之，係藉由夾具40自 Q 身的彈力將窗玻璃5夾持於第1構件41與第2構件42之 間。且，磁石50係位於檢測部60前方。 由此狀態，當窗玻璃5破損時，其強度會下降。即， 如第9圖所示般，當強化玻璃所構成的窗玻璃5 —部份破 損時，裂痕會遍佈窗玻璃5整體而使得其強度明顯降低（玻 璃破裂時玻璃強度會降低）。 如第10圖所示，隨著其強度降低，夾具40會藉其本 身的夾持力粉碎窗玻璃5之端部。即，藉由其本身的彈力 使由強化玻璃所構成的窗玻璃5之一部份完全粉碎（變成碎 -11- 201027071 片）。藉此，如第11圖所示，夾具40會掉落。 詳言之’如第9圖所示，因第2構件42之彈丈 玻璃5遭到按壓，而窗玻璃5抵接於夾具40之第 41上。於此狀態，如第1〇圖所示，在開口 44之局 撐的狀態下，窗玻璃5受第2構件42所按壓），開 的窗玻璃5被粉碎成碎片（窗玻璃5被破壞成倒U: 接著，如第11圖所示，夾具40會掉落。 第3圖之檢測部60處，窗玻璃5破損前之磁值 ❹ 61的輸出Vs 1，係顯示爲特定臨界値以上的數値， 窗玻璃5之破碎造成夾具40掉落後，磁性檢測器 出訊號不再顯示爲特定臨界値以上的數値。藉此， 出夾具40之掉落。 如此一來，利用強化玻璃之一部份破損時會全 龜裂使強度明顯下降的特性，可積極地降低未檢出 出的問題。 又，如第2圖所示，即便窗玻璃5不是位於全 時，由於使用具有立設部63的芯材62a、62b，因 窗玻璃5是開啓著，亦可於廣範圍內檢測出窗玻瑀 損。即，習知技術（專利文獻1)係檢測在窗玻璃全P 玻璃的移動，因此當窗玻璃不是位於全閉位置時價 測出窗玻璃之破損，但本實施形態中，即便爲了接 微開啓窗玻璃而使得窗玻璃不是位於全閉位置時， 測出窗玻璃之破損。 詳言之，即使是在乘客爲了換氣而於開啓窗戶 下停車的情況，亦即，有必要事先作成即便是窗戶 [使得窗 1構件 丨圍被支 口 44中 ?型）。 :檢測器 但隨著 61之輸 可檢測 面產生 、誤檢 閉位置 而即便 :5之破 I時之窗 ί無法檢 t氣等稍 亦可檢 1之狀態 1開啓至 -12- 201027071 —定程度之狀態（考慮到例如夏天爲了抑制車內溫度上昇 而將窗戶開啓例如7cm左右的狀態）亦能檢測出窗玻璃之 破損。空氣之導磁率低，當窗玻璃開啓使磁石50位於下方 位置時，造成磁性檢測器61之輸出降低（參考第7圖之Vs2 的波形）。於本實施狀態中，將芯材（core)作成朝上下延伸 的形狀，其下側之端部係設置於磁性檢測器61附近，且， 設置有夾著磁性檢測器61而左右對稱的芯材62a、62b。 藉此，沿縱方向延伸的芯材之立設部63係發揮磁力中之通 © 路的功用，即便磁石50稍微上下移動，芯材62a、62b(立 設部63)亦可吸收磁石50的磁力並傳達給磁性檢測器61。 又，第5圖之夾具40係具有彎折板彈簧用鋼板所形成 之對向的第1構件41與第2構件42，於設置有窗玻璃5 的第1構件41與第2構件之間，於窗玻璃5之面內，第1 構件41與第2構件42係於相互偏離的位置接觸窗玻璃5, 並朝向相互接近的方向施加彈力。藉此，因爲在窗玻璃5 之表面5a與內面5b之相異位置，向窗玻璃5施加力量， @ 隨著窗玻璃5之破損（隨著窗玻璃5之強度下降），可確實 地將窗玻璃5之端部壓碎並確實地檢測出窗玻璃5之破損。 又，於窗玻璃5之面內，第5圖中夾具40的第1構件 41接觸至窗玻璃5的接觸部與第2構件42接觸至窗玻璃5 的接觸部係相互離’且’第1構件41接觸至窗玻璃5的兩 接觸部係位於第2構件42接觸至窗玻璃5的接觸部之外圍 且相互連結。因此，如第9圖所示，第1構件41係抵接於 第2構件42與窗玻璃5之接觸部周圍的狀態下壓迫窗玻璃 5。即，第1構件處，於開口 44周圍支撐著窗玻璃5之狀 -13- 201027071 態下，於開口 44之內周緣的內部處按壓窗玻璃5。藉此， 如第10圖所示，能使得窗玻璃5之端部更容易粉碎而使得 夾具40確實地掉落。 第3圖中，藉由檢測部60(根據磁性檢測器61之輸出 値）來檢測出夾具40掉落，且於檢測出窗玻璃5之破損時 使得判斷部70之警報部80作動來發出警報。 依前述實施形態係可獲得以下之優點。 (1) 藉由設置一種由磁性材料所形成、與磁性檢測器61 Θ 呈磁性結合、至少具有沿上下方向延伸之立設部的芯材62a 與6 2b，即便窗玻璃不是位於全閉位置時亦可透過芯材62 a 與6 2b來將磁石50之磁力傳達給磁性檢測器61，並藉由 磁性檢測器61來檢測出磁石50所產生的磁場Η1»藉此， 即便窗玻璃不是位於全閉位置時亦可檢測窗玻璃之破損。 (2) 將磁石50固定於夾持著窗玻璃之端部的夾具40 上，且夾具40係具有於窗玻璃5面內相互偏離的位置處朝 向相互接近的方向施加彈力的第1構件41與第2構件42。 Q 因此，隨著窗玻璃5之破損係可確實地壓碎窗玻璃5之端 部。 (第2實施形態） 其次，針對與第1實施形態之相異點來說明第2實施 形態。 相對於第4圖，本實施形態之構成係如第12圖所示。 取代第4圖中的磁性檢測器6 1，第1 2圖中本實施形態亦 可用MR檢測器68(磁抗元件）。又，相對於第6圖，本實 施形態之構成係如第13圖所示。第14圖係顯示本實施形 -14- 201027071 態之開閉式窗玻璃破損檢測裝置3 0的電路構成。 第1 4圖中，開閉式窗玻璃破損檢測裝置3 0 磁石50、檢測部60以及判斷部70，該檢測部60 性開關90以及相反磁場產生部91。 磁性開關90係具備MR檢測器68 (磁抗元件 爲開關元件之NPN電晶體92。相反磁場產生部< 有電阻93、2個線圈94a與94b、以及電容95。 MR檢測器68之一端係連接至判斷部70，從 0 將電壓（例如5 volt)施加於MR檢測器68之一端j 測器68之另一端則連接至NPN電晶體92的基極 晶體92的集極係連接至MR檢測器68之判斷部 端。NPN電晶體92的射極係經由電阻93與線圈 的串聯電路而到達接地點。於電阻93與線圈94b 接點r經由電容95而到達接地點。 如第12圖、第13圖所示，線圈94a係纏繞 62a(core)。同樣地，線圈94b係纏繞於芯材62b @ 材62 a、62b之其他構成皆與第1實施形態相同。 62a、62b係由磁性材料（詳細說明係由高透磁率的 鋼）所組成，與構成磁性開關90的MR檢測器68 合，至少具有沿上下方向延伸的立設部，而且， 反磁場產生用線圈94a、94b。 藉由磁石50之磁場來開啓第14圖之磁性開 磁石50之磁場會使得流通於MR檢測器68的電 使得電流流經NPN電晶體92的基極，讓NPN電 呈開啓狀態。 係具備有 係具有磁 )、以及作 Η係具備 判斷部7 0 處。MR檢 丨。NPN電 7 0側的一 94a、 94b 之間的連 於芯材 。關於芯 即，芯材 高導磁鎳 呈磁性結 纏繞有相 關90。即， 流增大， :晶體9 2 -15- 201027071 隨著開啓磁性開關90(NPN電晶體92)，會於線圈94a、 94b處產生產生足以抵消該磁石50之磁場HI的相反磁場 H2。即，當開啓NPN電晶體92後會將一定之電流供給至 線圈94a、94b以產生相反磁場H2。藉以該相反磁場H2可 抵消磁石50之磁場H1。即，線圈94a、94b未流通有電流 時，透過芯材62a、62b來集中磁力，並以特定之磁通密度 對MR檢測器68施加磁場，但是當線圈94a、94b流通有 電流時可使得施加於MR檢測器68的磁通密度幾乎降爲 'φ 零。其結果，流通於MR檢測器68的電流變小，使得NPN 電晶體92呈關閉狀態，而停止將電流供給至線圈94a、94b。 藉此，線圈94a、94b所產生的相反磁場H2亦會變成 [零]。當線圈94a、94b所產生的相反磁場H2變成[零]時， 便會藉由磁石50之磁場H1來開啓磁性開關90(NPN電晶 體 92)。 反覆前述動作以使得磁性開關90進行開關動作。此 時，電阻93與電容95係構成延遲電路，藉由該延遲電路（電 Q 阻93與電容95)來延長當磁性開關90開啓時流通至線圈 94a、94b的電流而延長磁性開關90之開關周期。 第14圖之判斷部70係具備有控制部71、電流監控部 72、記憶體74以及分流電阻73。控制部71係經由分流電 阻73而連接至檢測部60的MR檢測器68，從控制部71 施加電壓給MR檢測器68，檢測該分流電阻73的電流。由 電流監控部72來接收因分流電阻73所流通的電流產生之 相對應電壓，再將其結果傳送給控制部7 1。控制部7 1係 使用CPU與可程式元件所構成，接收電流監控部72的輸 -16- 201027071 出訊號，根據該輸出訊號，當磁性開關90之開關周期較預 定之臨界値更短時，則判斷窗玻璃已破損而磁石5 0已掉 落。該臨界値等資訊係記憶於記億體中。當窗玻璃破損時 控制部7 1便藉由警報部8 0來實施警報。 其次，說明磁石50與MR檢測器68的距離、以及磁 性開關90的開關周期之間的關係。 第15圖（a)係顯示磁石50靠近MR檢測器68的情況， 第15圖（b)係顯示磁石50遠離MR檢測器68的情況。 Q 第16圖中縱軸係顯示流通於線圈94a、94b的電流（流 通於第14圖中τ點的電流）以及流通於第14圖中點的電 流，橫軸則表示時間。 第16圖（a)係顯示第15圖（a)中磁石位置較近時的作 動。第15圖（a)中由於磁石50之位置較靠近MR檢測器68, 故MR檢測器68所受磁石50之磁力作用較強。因此，爲 了抵消磁石50之磁力所必須供給至線圈94a、94b的電流 增加。因此，可延長磁性開關90從開啓變爲關閉的時間。 φ 另一方面，第16圖（b)係顯示第15圖（b)中磁石位置較遠時 的作動。第15圖（b)中由於磁石50之位置遠離MR檢測器 68，故MR檢測器68所受磁石50之磁力作用較弱。因此， 爲了抵消磁石50之磁力所必須供給至線圈94a、94b的電 流減少。因此，可縮短磁性開關90從開啓變爲關閉的時間。 如此一來，磁性開關90之開關周期係反比於50a和 MR檢測器68之間的距離。 本實施形態之開閉式窗玻璃破損檢測裝置的作動如 下。 -17- 201027071 藉由磁石50之磁場來開啓磁性開關90後，隨著磁性 開關90之開啓，藉由連接至磁性開關90的相反磁場產生 用線圈94a、94b來產生足以抵消該磁石50之磁場H1的相 反磁場H2，並使得磁性開關90關閉。然後，判斷部70係 根據磁性開關90的開關周期來檢測出因窗玻璃5之破損所 造成之磁石50掉落。 此處，單純之線圈的磁通勢（magnetomotive force)較 弱，難以抵消肥粒鐵磁石50的磁力。本實施形態中，與磁 © 性開關90磁性結合且纏繞有相反磁場產生用線圈94a、94b 之由磁性材料所構成的芯材62a、62b的一部份，係至少沿 上下方向延伸，因此即便窗玻璃5不是位於全閉位置時亦 可通過該芯材62a、62b將磁石50之磁力傳達給磁性開關 90。詳言之，如第17圖所示，當窗玻璃5不在全閉位置處 而爲了換氣將窗玻璃稍微開啓時，會使磁石50位於稍低位 置，但於此情況下亦可獲得高輸出準位的訊號。又，可有 效率地對磁性開關90施加相反磁場。藉此，可檢測出窗玻 φ 璃之破損。 (第3實施形態） 其次，針對與第1實施形態之相異點來說明第3實施 形態。 如第18圖、第19圖所示，預防不法侵入用的開閉式 窗玻璃破損檢測裝置1 0 0係設置於車門1之內部。破損檢 測裝置1 00係具有夾具1 1 〇以及檢測部60。 夾具110係設置於窗玻璃5之下端部。夾具110係具 備有平板構件111與環形彈簧112,並以特定以上之力量來 -18- 201027071 夾持（把持）窗玻璃5之下端部。詳言之，夾具110之平板 構件111係由金屬板所構成，平板構件111於背面側具有 左右分隔地作設置之受壓部（背板部）Ula與111b，且於 正面側具有設置於該受壓部Ilia與111b中央之按壓部 lllc(按壓片）。受壓部111a、111b之間係形成有朝背面側 呈現C字型的凹陷部（凹陷部111 d)。藉由底板部me來連 結屬背面側之構件的受壓部1 1 1 a、1 1 1 b及凹陷部1 1 1 d、以 及正面側的按壓部111c。在平板構件111之受壓部111a、 Q lllb與按壓部lllc之間設置有窗玻璃5。 環形彈簧1 1 2，係一端係位於平板構件1 1 1之凹陷部 1 1 1 d的背面側，另一端則位於平板構件1 1 1之按壓部1 1 1 C 的正面側，且以施加一使兩端變窄的彈力。藉此，平板構 件1 1 1之受壓部1 1 1 a、1 1 1 b係抵接於窗玻璃5之一側面的 狀態下，按壓部1 1 1 c係從窗玻璃5之另一側面施加特定以 上之壓力給窗玻璃5。 夾具Π0之平板構件111的按壓部lllc之正面側係設 & 置有磁石115(永久磁石）。另一方面，於內側壁板3上檢測 部60係與磁石1 1 5對向地作配置，使得檢測部60(磁性檢 測器61)之輸出係對應於迄至磁石115爲止的距離L之構 成。可藉由檢測部6 0來檢測出伴隨窗玻璃5破損所造成之 夾具1 1 〇之至少一部份的位移。檢測部6 0係經由控制器 121而連接至警報裝置122。 如第4圖、第6圖所述，檢測部6 0之磁性檢測器61 係與芯材（62a、62b)呈磁性結合。 其次，說明如此構成之開閉式窗玻璃破損檢測裝置的 -19- 201027071 作用，即，說明當窗玻璃5損壞（龜裂）時的作動。 在平時，設置於窗玻璃5端部的夾具110係挾持窗玻 璃5之端部。詳言之，夾具Π0之平板構件111係藉由環 形彈簧112來夾持窗玻璃5。又，檢測部60與磁石115之 間的距離爲L 1。 由此狀態，當窗玻璃5破損時，其強度會下降。即， 當強化玻璃所構成的窗玻璃5之一部份破損時，裂痕會遍 佈窗玻璃5整體而使其強度明顯降低（玻璃破裂時會降低玻 © 璃強度）。 隨著其強度降低，夾具11〇藉其本身的夾持力粉碎窗 玻璃5之端部（下端部）。即，藉由環形彈簧1 1 2之彈力， 使強化玻璃所構成的窗玻璃5之一部份完全粉碎（變成碎 片）。 伴隨著此夾具110所造成之窗玻璃5的一部份完全粉 碎，如第20圖所示，使得夾具110之平板構件111的按壓 部111c產生位移（屬夾具110之一部份的按壓部111c產生 Q 位移）。詳言之，窗玻璃5與按壓部111c接觸的部份係受 該按壓部111c之按壓，產生位移迄至抵接凹陷部uid爲 止。該夾具1 1 0之按壓部111 C的位移係藉檢測部60來檢 測。即，伴隨著夾具1 1 〇之按壓部11 1 c的位移，使檢測部 6〇與磁石115之間的距離擴大成爲L2，比在第18圖中的 L1更大。因此，即便是在窗玻璃5伴隨窗玻璃5之破損而 未被完全粉碎且留有殘骸之情況，亦可確實地檢測出窗玻 璃5之破損。 在藉由檢測部60檢測出窗玻璃5之破損時，控制器 -20- 201027071 1 2 1係作動警報裝置1 22並發出警報。 另外，即使在窗玻璃5 —破損時夾具110將窗玻璃5 完全粉碎而讓夾具脫落，由於檢測部60前方無磁石 115故亦可藉由檢測部60來檢測出窗玻璃5之破損。 關於芯材（62a、62b)與磁性檢測器61呈磁性結合之情 況的作用，係與第1實施形態所述相同。即，係檢測出設 置在可自由開閉車輛之開口部的窗玻璃5處並可產生出固 定磁場的磁石Π5所產生的磁場，並根據該磁場來檢測出 Q 窗玻璃5之破損。此時’將磁性材料所構成之芯材62a、 6 2b的磁性與用以檢測磁石1 1 5所產生之磁場的磁性檢測 器61(磁性檢測部）結合，且芯材62a、62b係至少具有沿上 下方向延伸的立設部。因此，芯材62a、62b之至少一部份 係沿上下方向延伸，因此即使窗玻璃5不是位於全閉位置 時亦可通過該芯材62a、62b而將磁石115之磁力傳達給磁 性檢測器6 1，以藉由磁性檢測器6 1來檢測出該磁石1 1 5 所產生的磁場，藉以檢測出窗玻璃5之破損。 0 第18圖、第19圖、第20圖所述本實施形態之構成亦 適用於第2實施形態。此時，藉由設置在可自由開閉車輛 之開口部的窗玻璃5處並可產生出固定磁場的磁石115所 產生的磁場來開啓磁性開關90。隨著磁性開關90之開啓， 藉由連接至磁性開關90的相反磁場產生用線圈94a、94b 來產生抵消該磁石115之磁場的相反磁場。藉此，可一邊 關閉磁性開關90 —邊根據磁性開關90的切換周期來檢測 出窗玻璃5之破損。此時，由磁性材料所構成之芯材62a、 6 2b，係與磁性開關90(MR檢測器68)呈磁性結合，且芯材 -21- 201027071 62a、62b係纏繞有相反磁場產生用線圏94a、94b並至少具 有沿上下方向延伸的立設部。因此’與磁性開關90呈磁性 結合且纏繞有相反磁場產生用線圈94a、94b的芯材62a、 6 2 b，係至少具有沿上下方向延伸的立設部’因此即使窗玻 璃5不是位於全閉位置時亦可通過該芯材62a、62b將磁石 115之磁力傳達給磁性開關90’且能有效率地賦予相反磁 場，藉以檢測出窗玻璃5之破損。 本發明之實施形態並未限定於前述’亦可具體化如下。 〇 芯材（62a、62b)除了高導磁鎳鋼以外，其他亦可使用 例如鐵基軟磁材料（finemet)、非晶質層積線芯所形成。 亦可使用霍爾元件（Hall element)來取代磁性檢測器 6 1° 第14圖中係藉由MR檢測器68與NPN電晶體92來 構成磁性開關90，但亦可使用舌簧開關來構成磁性開關來

Each of the core members 62a and 62b is formed of one bar member, and is composed of an upright portion 63 extending in the vertical direction and a horizontal portion 63 extending in the L direction from the lower end of the upright portion 63 in the horizontal direction. . The upper end portions of the upright portions 63 of the core members 62a, 62b are disposed at positions substantially equal to the height of the magnet 50 when the window glass 5 is fully closed (the magnets 50 are spaced apart from each other by a specific distance in the Y direction). Further, the magnetic detector 61 is provided near the front end surface of the horizontal portion 64 of the core members 62a and 62b. Thereby, the magnetic detector 61 as the magnetic detecting portion is magnetically coupled to the core members 62a and 62b, and one of the core members 62a and 62b extends in the vertical direction. The magnetic field (magnetic force) of the magnet 50 is concentrated and transmitted to the magnetic detector 61 by the core materials 62a, 62b, and the magnetic flux density of the magnetic detector 61 can be increased. The magnetic detector 61 outputs a signal in response to a magnetic field (magnetic strength). As shown in Fig. 3, the magnetic detector 61 is connected to the determination unit 70. The judging unit 70 is provided with an A/D converter and a microcomputer, and the microcomputer can receive the A/D converted signal from the magnetic detector 61. Further, since the core members 62a and 62b are provided with the standing portion 63 extending in the vertical direction, the magnetic detector 61 can be widely used in comparison with the Vs2 in the case of the coreless material (refer to Fig. 7). Output Vsl (refer to Figure 7). As a result, the position of the magnet 50 can be measured in a wide range of inspections -10- 201027071. That is, as shown in Fig. 8, when the window glass is not opened at the fully closed position but slightly opened for the purpose of ventilation, the magnet 50 is placed at a slightly lower position, but in this case, a high output can be obtained. The signal of the level. Then, the judging section 70 of Fig. 3 detects that the magnet 50 is dropped by the damage of the window glass based on the magnetic field detected by the magnetic detector 61, i.e., based on the detector output (Vs 1 ). In Fig. 3, the determination unit 70 is connected to the alarm unit 80. Next, the function of the open-closed window glass breakage detecting device thus constructed, that is, the operation when the window glass 5 is damaged (cracked) will be described. Generally, the window glass 5 is in a fully closed or slightly opened state when the passenger leaves the vehicle. The determining unit 70 detects the position of the window glass 5 from the detector output level (Vs 1) (Fig. 7), and sets the glass to the fully closed or slightly opened state when the handbrake is operated. Breakage detection mode. On the other hand, as shown in Fig. 5, the jig 40 provided at the end of the window glass 5 holds the end of the window glass 5. More specifically, the window glass 5 is sandwiched between the first member 41 and the second member 42 by the elastic force of the jig 40 from the body of the Q. Further, the magnet 50 is located in front of the detecting unit 60. In this state, when the window glass 5 is broken, its strength is lowered. That is, as shown in Fig. 9, when the window glass 5 composed of the tempered glass is partially broken, the cracks may spread throughout the window glass 5 so that the strength thereof is remarkably lowered (the glass strength is lowered when the glass is broken). As shown in Fig. 10, as the strength thereof is lowered, the jig 40 pulverizes the end portion of the window glass 5 by its own clamping force. That is, a part of the window glass 5 made of tempered glass is completely pulverized by its own elastic force (becomes broken -11-201027071 pieces). Thereby, as shown in Fig. 11, the jig 40 is dropped. In detail, as shown in Fig. 9, the glass 5 of the second member 42 is pressed, and the window glass 5 abuts on the 41st of the jig 40. In this state, as shown in Fig. 1, in the state in which the opening 44 is supported, the window glass 5 is pressed by the second member 42, and the opened window glass 5 is pulverized into pieces (the window glass 5 is broken into Inverted U: Next, as shown in Fig. 11, the jig 40 is dropped. At the detecting portion 60 of Fig. 3, the output Vs1 of the magnetic value ❹ 61 before the window glass 5 is broken is expressed as a specific critical value or more. After several times, the crushing of the window glass 5 causes the clamp 40 to fall off, and the magnetic detector output signal is no longer displayed as a number above a certain critical threshold. Thereby, the clamp 40 is dropped. Thus, the tempered glass is utilized. A part of the damage will be completely cracked and the strength will be significantly reduced, which can actively reduce the undetected problem. Moreover, as shown in Fig. 2, even if the window glass 5 is not at full time, it has a stand-up due to use. In the core materials 62a and 62b of the portion 63, the window glass 5 is opened, and the window glass damage can be detected in a wide range. That is, the conventional technique (Patent Document 1) detects the movement of the P glass in the window glass. Therefore, when the window glass is not in the fully closed position, the price of the window glass is measured, but this In the embodiment, even if the window glass is not in the fully closed position in order to open the window glass, the damage of the window glass is detected. In detail, even if the passenger stops under the opening window in order to change the air, That is, it is necessary to make a window in advance (so that the window 1 member is surrounded by the shape of the branch 44). : Detector, but with the 61 detectable surface generated, misdetected closed position and even: 5 broken I window ί can not check t gas, etc. can also be detected 1 state 1 open to -12- 201027071 - set In the state of the degree (for example, in the summer, in order to suppress the temperature rise in the vehicle, the window is opened, for example, in a state of about 7 cm), the damage of the window glass can also be detected. The magnetic permeability of the air is low, and when the window glass is opened to place the magnet 50 in the lower position, the output of the magnetic detector 61 is lowered (refer to the waveform of Vs2 in Fig. 7). In the present embodiment, the core is formed in a shape extending upward and downward, and the lower end portion is provided in the vicinity of the magnetic detector 61, and a core material symmetrically sandwiched between the magnetic detectors 61 is provided. 62a, 62b. Thereby, the standing portion 63 of the core material extending in the longitudinal direction functions as a passage of the magnetic force, and even if the magnet 50 moves up and down slightly, the core members 62a and 62b (the standing portion 63) can absorb the magnet 50. The magnetic force is transmitted to the magnetic detector 61. Further, the jig 40 of the fifth embodiment has the first member 41 and the second member 42 which are formed by the steel plate for bending the leaf spring, and is disposed between the first member 41 and the second member in which the window glass 5 is provided. In the surface of the window glass 5, the first member 41 and the second member 42 are in contact with the window glass 5 at positions offset from each other, and an elastic force is applied in a direction in which they approach each other. Thereby, since the force is applied to the window glass 5 at a position different from the surface 5a of the window glass 5 and the inner surface 5b, @the damage of the window glass 5 (as the strength of the window glass 5 decreases) can be surely The end portion of the window glass 5 is crushed and the damage of the window glass 5 is surely detected. Further, in the plane of the window glass 5, the contact portion of the first member 41 of the jig 40 in contact with the window glass 5 in FIG. 5 is in contact with the contact portion of the second member 42 to the window glass 5, and is the first and the first. The two contact portions of the member 41 that are in contact with the window glass 5 are located at the periphery of the contact portion where the second member 42 contacts the window glass 5 and are coupled to each other. Therefore, as shown in Fig. 9, the first member 41 presses the window glass 5 in a state in which it is in contact with the periphery of the contact portion between the second member 42 and the window glass 5. That is, the first member is supported by the window glass 5 around the opening 44. In the state of -13-201027071, the window glass 5 is pressed inside the inner periphery of the opening 44. Thereby, as shown in Fig. 10, the end portion of the window glass 5 can be more easily pulverized so that the jig 40 is surely dropped. In the third diagram, the detecting unit 60 detects the drop of the jig 40 based on the output of the magnetic detector 61, and when the damage of the window glass 5 is detected, the alarm unit 80 of the determining unit 70 is activated to issue an alarm. . According to the foregoing embodiment, the following advantages are obtained. (1) By providing a core material 62a and 62b formed of a magnetic material and magnetically coupled to the magnetic detector 61 、 and having at least an upright portion extending in the up and down direction, even if the window glass is not in the fully closed position The magnetic force of the magnet 50 can also be transmitted to the magnetic detector 61 through the core materials 62a and 62b, and the magnetic field generated by the magnet 50 can be detected by the magnetic detector 61. Thus, even if the window glass is not located at all The damage of the window glass can also be detected when the position is closed. (2) The magnet 50 is fixed to the jig 40 that sandwiches the end portion of the window glass, and the jig 40 has the first member 41 that applies an elastic force toward the mutually approaching position at positions deviating from each other in the plane of the window glass 5 The second member 42. Therefore, the damage of the window glass 5 can surely crush the end of the window glass 5. (Second embodiment) Next, a second embodiment will be described with respect to differences from the first embodiment. The configuration of this embodiment is as shown in Fig. 12 with respect to Fig. 4. Instead of the magnetic detector 6-1 in Fig. 4, the MR detector 68 (magnetic ray element) can also be used in the present embodiment. Further, with respect to Fig. 6, the configuration of this embodiment is as shown in Fig. 13. Fig. 14 is a view showing the circuit configuration of the open-closed window glass breakage detecting device 30 of the present invention in the form of -14-201027071. In the first and fourth drawings, the open and closed window glass damage detecting device 30 magnet 50, the detecting unit 60, and the determining unit 70, the detecting unit 60 switch 90 and the opposite magnetic field generating unit 91. The magnetic switch 90 is provided with an MR detector 68 (the NPN transistor 92 whose magnetic component is a switching element. The opposite magnetic field generating portion) < There are a resistor 93, two coils 94a and 94b, and a capacitor 95. One end of the MR detector 68 is connected to the judging section 70, and a voltage (for example, 5 volt) is applied from 0 to one end of the MR detector 68, and the other end of the detector 68 is connected to the base crystal 92 of the NPN transistor 92. The collector is connected to the judging section of the MR detector 68. The emitter of the NPN transistor 92 reaches the ground point via a series circuit of the resistor 93 and the coil. The contact point r between the resistor 93 and the coil 94b reaches the ground point via the capacitor 95. As shown in Fig. 12 and Fig. 13, the coil 94a is wound 62a (core). Similarly, the other configuration in which the coil 94b is wound around the core member 62b @62a, 62b is the same as in the first embodiment. 62a and 62b are composed of a magnetic material (specifically, a steel having high magnetic permeability), and are combined with an MR detector 68 constituting the magnetic switch 90, and have at least an upright portion extending in the vertical direction, and the diamagnetic field is generated. Coils 94a, 94b. The magnetic field of the magnetic magnetism 50 of Fig. 14 is turned on by the magnetic field of the magnet 50 so that the electric current flowing through the MR detector 68 causes a current to flow through the base of the NPN transistor 92, causing the NPN to be turned on. The system has a magnetic system, and the system has a determination unit 70. MR examination. The NPN is connected to the core material between a 94a and 94b on the 70 side. Regarding the core, the core material is highly magnetic nickel with a magnetic knot wound with a correlation of 90. That is, the flow is increased, crystal: 9 2 -15 - 201027071 As the magnetic switch 90 (NPN transistor 92) is turned on, an opposite magnetic field H2 is generated at the coils 94a, 94b to generate a magnetic field HI sufficient to cancel the magnet 50. That is, when the NPN transistor 92 is turned on, a certain current is supplied to the coils 94a, 94b to generate the opposite magnetic field H2. The magnetic field H1 of the magnet 50 can be cancelled by the opposite magnetic field H2. In other words, when current is not supplied to the coils 94a and 94b, the magnetic force is concentrated by the core members 62a and 62b, and a magnetic field is applied to the MR detector 68 at a specific magnetic flux density. However, when the current is passed through the coils 94a and 94b, the application can be performed. The magnetic flux density at the MR detector 68 is almost reduced to 'φ zero. As a result, the current flowing through the MR detector 68 becomes small, so that the NPN transistor 92 is turned off, and the supply of current to the coils 94a, 94b is stopped. Thereby, the opposite magnetic field H2 generated by the coils 94a, 94b also becomes [zero]. When the opposite magnetic field H2 generated by the coils 94a, 94b becomes [zero], the magnetic switch 90 (NPN electric crystal 92) is turned on by the magnetic field H1 of the magnet 50. The foregoing action is repeated to cause the magnetic switch 90 to perform a switching operation. At this time, the resistor 93 and the capacitor 95 constitute a delay circuit, and the delay circuit (the electric Q resistor 93 and the capacitor 95) extends the current flowing to the coils 94a, 94b when the magnetic switch 90 is turned on to extend the switch of the magnetic switch 90. cycle. The determination unit 70 of Fig. 14 includes a control unit 71, a current monitoring unit 72, a memory 74, and a shunt resistor 73. The control unit 71 is connected to the MR detector 68 of the detecting unit 60 via the shunt resistor 73, and applies a voltage from the control unit 71 to the MR detector 68 to detect the current of the shunt resistor 73. The current monitoring unit 72 receives the corresponding voltage generated by the current flowing through the shunt resistor 73, and transmits the result to the control unit 71. The control unit 71 is configured by using a CPU and a programmable component, and receives a signal output from the current monitoring unit 72, and according to the output signal, when the switching period of the magnetic switch 90 is shorter than a predetermined threshold, It is judged that the window glass has been broken and the magnet 50 has fallen. The information such as the critical threshold is stored in the body of the billion. When the window glass is broken, the control unit 71 performs an alarm by the alarm unit 80. Next, the relationship between the distance between the magnet 50 and the MR detector 68 and the switching period of the magnetic switch 90 will be described. Fig. 15(a) shows the case where the magnet 50 is close to the MR detector 68, and Fig. 15(b) shows the case where the magnet 50 is away from the MR detector 68. Q In Fig. 16, the vertical axis shows the current flowing through the coils 94a and 94b (the current flowing through the point τ in Fig. 14) and the current flowing through the point in Fig. 14, and the horizontal axis indicates the time. Fig. 16(a) shows the operation when the magnet position is relatively close in Fig. 15(a). In Fig. 15(a), since the position of the magnet 50 is closer to the MR detector 68, the magnetic force applied to the magnet 50 by the MR detector 68 is stronger. Therefore, the current that must be supplied to the coils 94a, 94b is increased in order to cancel the magnetic force of the magnet 50. Therefore, the time from when the magnetic switch 90 is turned on to off can be extended. φ On the other hand, Fig. 16(b) shows the operation when the magnet position is far away in Fig. 15(b). In Fig. 15(b), since the position of the magnet 50 is away from the MR detector 68, the magnetic force applied to the magnet 50 by the MR detector 68 is weak. Therefore, the current that must be supplied to the coils 94a, 94b is reduced in order to cancel the magnetic force of the magnet 50. Therefore, the time from when the magnetic switch 90 is turned on to off can be shortened. As such, the switching period of the magnetic switch 90 is inversely proportional to the distance between 50a and the MR detector 68. The operation of the opening and closing type window glass breakage detecting device of this embodiment is as follows. -17- 201027071 After the magnetic switch 90 is turned on by the magnetic field of the magnet 50, with the opening of the magnetic switch 90, the magnetic field generating coils 94a, 94b connected to the magnetic switch 90 generate a magnetic field sufficient to cancel the magnet 50. The opposite magnetic field H2 of H1 causes the magnetic switch 90 to close. Then, the judging section 70 detects that the magnet 50 is dropped by the breakage of the window glass 5 based on the switching period of the magnetic switch 90. Here, the magnetomotive force of the simple coil is weak, and it is difficult to cancel the magnetic force of the ferrite magnet 50. In the present embodiment, a part of the core materials 62a and 62b made of a magnetic material which are magnetically coupled to the magnetic-inductive switch 90 and wound with the opposite-field generating coils 94a and 94b are extended at least in the vertical direction, so that even When the window glass 5 is not in the fully closed position, the magnetic force of the magnet 50 can be transmitted to the magnetic switch 90 through the core members 62a and 62b. In detail, as shown in Fig. 17, when the window glass 5 is not in the fully closed position and the window glass is slightly opened for ventilation, the magnet 50 is placed at a slightly lower position, but in this case, a high output can be obtained. The signal of the level. Moreover, the opposite magnetic field can be applied to the magnetic switch 90 efficiently. Thereby, the damage of the window glass φ glass can be detected. (Third embodiment) Next, a third embodiment will be described with respect to differences from the first embodiment. As shown in Figs. 18 and 19, the open/close window glass breakage detecting device 100 for preventing illegal entry is provided inside the door 1. The damage detecting device 100 has a jig 1 1 〇 and a detecting portion 60. The jig 110 is disposed at the lower end of the window glass 5. The jig 110 is provided with a plate member 111 and a ring spring 112, and clamps (holds) the lower end portion of the window glass 5 with a specific force of -18-201027071. In detail, the plate member 111 of the jig 110 is composed of a metal plate, and the plate member 111 has pressure receiving portions (back plate portions) U1a and 111b which are provided to the left and right sides on the back side, and is provided on the front side. Pressing portions 11c (pressing sheets) at the center of the pressure receiving portions Ilia and 111b. A depressed portion (depressed portion 111d) having a C-shape toward the back side is formed between the pressure receiving portions 111a and 111b. The pressure receiving portions 1 1 1 a, 1 1 1 b and the recessed portions 1 1 1 d of the members on the back side are joined by the bottom plate portion me, and the pressing portions 111c on the front side. A window glass 5 is provided between the pressure receiving portions 111a and Q11b of the plate member 111 and the pressing portion 111c. The ring spring 1 1 2 has one end on the back side of the recessed portion 1 1 1 d of the flat plate member 1 1 1 and the other end on the front side of the pressing portion 1 1 1 C of the plate member 1 1 1 and is applied with a The elastic force that narrows the ends. Thereby, in a state where the pressure receiving portions 1 1 1 a and 1 1 1 b of the plate member 1 1 1 are in contact with one side surface of the window glass 5, the pressing portion 1 1 1 c is from the other side of the window glass 5 A specific pressure is applied to the glazing 5. The front side of the pressing portion 111c of the plate member 111 of the jig Π0 is provided with a magnet 115 (permanent magnet). On the other hand, the detecting portion 60 on the inner wall panel 3 is disposed opposite to the magnet 1 15 such that the output of the detecting portion 60 (magnetic detector 61) corresponds to the distance L up to the magnet 115. . The displacement of at least a portion of the jig 1 1 〇 caused by the breakage of the window glass 5 can be detected by the detecting portion 60. The detecting unit 60 is connected to the alarm device 122 via the controller 121. As shown in Fig. 4 and Fig. 6, the magnetic detector 61 of the detecting portion 60 is magnetically coupled to the core members (62a, 62b). Next, the action of -19-201027071 of the open-closed window glass breakage detecting device thus constructed will be explained, that is, the operation when the window glass 5 is damaged (cracked) will be described. In the normal state, the jig 110 provided at the end of the window glass 5 holds the end of the window glass 5. In detail, the plate member 111 of the jig Π 0 holds the window glass 5 by the ring spring 112. Further, the distance between the detecting portion 60 and the magnet 115 is L 1 . In this state, when the window glass 5 is broken, its strength is lowered. That is, when a part of the window glass 5 made of the tempered glass is broken, the crack spreads over the entire window glass 5 and the strength thereof is remarkably lowered (the glass strength is lowered when the glass is broken). As the strength thereof is lowered, the jig 11 pulverizes the end portion (lower end portion) of the window glass 5 by its own clamping force. That is, a part of the window glass 5 made of the tempered glass is completely pulverized (becomes into pieces) by the elastic force of the ring spring 1 1 2 . A part of the window glass 5 caused by the jig 110 is completely pulverized, and as shown in Fig. 20, the pressing portion 111c of the plate member 111 of the jig 110 is displaced (the pressing portion 111c which is a part of the jig 110) Generate Q displacement). More specifically, the portion of the window glass 5 that is in contact with the pressing portion 111c is pressed by the pressing portion 111c, and the displacement is caused until the abutting recess portion uid. The displacement of the pressing portion 111 C of the jig 1 10 is detected by the detecting portion 60. That is, with the displacement of the pressing portion 11 1 c of the jig 1 1 ,, the distance between the detecting portion 6 〇 and the magnet 115 is increased to L2, which is larger than L1 in Fig. 18. Therefore, even if the window glass 5 is not completely pulverized and remains with the damage of the window glass 5, the damage of the window glass 5 can be surely detected. When the detecting unit 60 detects breakage of the window glass 5, the controller -20-201027071 1 2 1 activates the alarm device 1 22 and issues an alarm. Further, even when the window glass 5 is broken, the jig 110 completely pulverizes the window glass 5 to cause the jig to fall off, and since the magnet 60 is not in front of the detecting portion 60, the damage of the window glass 5 can be detected by the detecting portion 60. The action of the core material (62a, 62b) and the magnetic detector 61 being magnetically coupled is the same as that described in the first embodiment. In other words, the magnetic field generated by the magnet Π 5 which is provided in the window glass 5 which can open and close the opening of the vehicle and which can generate a fixed magnetic field is detected, and the damage of the Q window glass 5 is detected based on the magnetic field. At this time, the magnetic properties of the core materials 62a and 62b composed of the magnetic material are combined with the magnetic detector 61 (magnetic detecting portion) for detecting the magnetic field generated by the magnet 115, and the core materials 62a and 62b have at least An upright portion extending in the up and down direction. Therefore, at least a portion of the core members 62a, 62b extend in the up and down direction, so that the magnetic force of the magnet 115 can be transmitted to the magnetic detector 6 through the core members 62a, 62b even when the window glass 5 is not in the fully closed position. 1. The magnetic field generated by the magnet 1 15 is detected by the magnetic detector 61 to detect breakage of the window glass 5. The configuration of the present embodiment described in Figs. 18, 19, and 20 is also applicable to the second embodiment. At this time, the magnetic switch 90 is turned on by a magnetic field generated by the magnet 115 which is provided at the opening of the openable and closable vehicle and which can generate a fixed magnetic field. As the magnetic switch 90 is turned on, the opposite magnetic field that cancels the magnetic field of the magnet 115 is generated by the opposite magnetic field generating coils 94a, 94b connected to the magnetic switch 90. Thereby, the breakage of the window glass 5 can be detected based on the switching period of the magnetic switch 90 while the magnetic switch 90 is closed. At this time, the core materials 62a and 62b composed of a magnetic material are magnetically coupled to the magnetic switch 90 (MR detector 68), and the core material-21-201027071 62a, 62b is wound with a reverse magnetic field generating wire. 94a and 94b have at least an upright portion extending in the up and down direction. Therefore, the core materials 62a and 6 2 b which are magnetically coupled to the magnetic switch 90 and are wound with the opposite magnetic field generating coils 94a and 94b have at least an upright portion extending in the up and down direction. Therefore, even if the window glass 5 is not fully closed At the position, the magnetic force of the magnet 115 can be transmitted to the magnetic switch 90' through the core members 62a and 62b, and the opposite magnetic field can be efficiently applied, thereby detecting damage of the window glass 5. The embodiment of the present invention is not limited to the above, and may be embodied as follows.芯 The core material (62a, 62b) may be formed of, for example, an iron-based soft magnetic material (finemet) or an amorphous laminated core, in addition to the high magnetic permeability nickel steel. It is also possible to use a Hall element instead of the magnetic detector 6 1°. In Fig. 14, the magnetic switch 90 is formed by the MR detector 68 and the NPN transistor 92, but a reed switch can also be used to form the magnetic Switch to replace. Here, when the actuator is not actuated, the reed contact inside the reed switch is in a non-contact state (OFF). When the actuator is actuated, the reed is magnetized by the externally applied magnetic force Q, and the reed contact contacts. The reed contact that is in contact after the magnetic force is removed becomes non-contact due to the elasticity. The configuration shown in Figs. 21(a) and (b) may be used instead of Fig. 4. In Fig. 21(a), the core materials 97a and 97b are formed in an L shape and have an upright portion. In Fig. 21(b), each of the core members 98a and 98b is formed in a straight line shape, and the two core members 98a and 98b are formed to extend in the upper and lower directions to form a V shape. Further, as shown in Fig. 22 (a) and (b), the coils 94a, 94b may be wound around the core members 97a, 97b, 98a, 98b shown in Figs. 21(a) and (b). To replace the composition of Figure 12. -22- 201027071 Although the core materials 62a and 62b are provided on the right and left sides of the magnetic detector 61 or the MR detector 68, the core material may be provided only on one of them. As the window regulator, an X-arm window regulator is used, but a cable window regulator can also be used. The drive unit is not limited to a motor, but may be operated by a passenger. The window glass breakage detection device is suitable for the right front door of the passenger car. Of course, it can also be applied to other side doors. In addition to the side door, it can also be applied to the rear door or the open and closed glass sunroof installed on the roof. The jig 40 is provided at the lower end portion of the window glass 5, but is not limited thereto, and may be provided, for example, at a lower portion of the side surface of the window glass 5. The point is that the position of the end of the window glass is not conspicuous in the interior of the door 1. [Fig. 1 is a schematic view of the window glass damage detecting device according to the first to third embodiments of the present invention.
