在這種以馬達等來作爲驅動源的裝置中，在將門完全 關閉之後，爲了防止馬達燒掉或爲了節省電力而需要切斷 馬達的通電，而將馬達關閉的話，會伴隨著其輸出軸的自 由旋轉而讓門可任意移動，所以需要另外設置用來將門保 持在完全關閉狀態的鎖定裝置。 以往，作爲用來讓門完全關閉及鎖定的手段，則像在 曰本特開平4 一 2 2 8 7 8 8號公報所揭示的裝置。該裝 置，是藉由進給絲桿機構來進行門的開閉，並且在門達到 完全關閉的階段，會藉由彈簧的彈力來讓鎖定手段自動作 動，來鎖定住該完全關閉狀態。 【發明欲解決的課題】 以往，爲了要更確實地進行上述鎖定動作，已開發出 了使用螺管線圏等的電力驅動源能切換爲將門固定在完全 本紙張尺度適用中國國家標準（CNS ) A4規格（210X297公釐） ----r--r---·裝-- (請先閱讀背面之注意事項再填寫本頁) 訂 經濟部智慧財產局員工消費合作社印製 -4 -

置中，並不像上述日本特開平4 一 2 2 8 7 8 8號公報中 所揭示的裝置是與門的開閉動作連動來進行鎖定切換，有 可能會在車輛行駛中誤將鎖定解除。 也就是說，車輛用門原則上在車輛行駿中是禁止開閉 的’所以對於這種與門的開閉連動來進行鎖定切換的裝置 ’在車輛行駛中是不用擔心會讓門鎖解除，可是在是藉由 與車輛用門的開閉狀態另外獨立的螺管線圈等來進行鎖定 切換的鎖定裝置中，有可能在車輛行駿中由於誤將鎖定解 除指令輸入而讓鎖定解除。 經濟部智慧財產局員工消費合作社印製 本發明鑒於這種情形，其目的在於提供一種車輛用門 的鎖定控制方法以及鎖定裝置，希望能夠確實防止在車輛 行駛時門鎖開啓，以提升安全性。 【用來解決課題的手段】 作爲用來解決上述課題的手段，本發明，是使用包含 有：會切換到將車輛用門鎖定在完全關閉位置的鎖定位置 與從該鎖定位置退開而解放上述車輛用門的非鎖定位置的 鎖定切換構件、用來將該鎖定切換構件朝向上述鎖定位置 本紙張尺度適用中國國家標準（CNS ) A4規格（210X297公釐） ~ 1221816 A7 ___B7 五、發明説明（3 ) (請先閲讀背面之注意事項再填寫本頁) 側彈壓的彈簧構件、以及藉由從電源接受電源供給以其電 磁力來將上述鎖定切換構件抵抗上述彈簧構件的彈壓力而 切換到上述非鎖定位置的電磁驅動裝置之鎖定裝置，來進 行車輛用門的鎖定控制的方法，當車輛的行駛速度未達到 一定的速度時，會根據來自於外部的指令來控制導通或切 斷從上述電源對電磁驅動裝置的供電，當車輛的行駛速度 在上述一定速度以上時，不管上述指令的輸入如何，會禁 止從上述電源對電磁驅動裝置的供電。 藉由這種方法，在車輛的行駛速度未達到一定的速度 的安全的狀態中，是藉由根據從外部所輸入的指令來導通 或切斷從上述電源對電磁驅動裝置的供電，來進行平常的 鎖定控制，另一方面，當車輛的行駛速度在上述一定速度 以上時，則不管上述指令的輸入如何，會禁止從上述電源 對電磁驅動裝置的供電，。則可以確實地防止在車輛行駛 時誤將門的鎖定解除這樣的情形。 經濟部智慧財產局員工消費合作社印製 上述供電禁止的解除，雖然也可以在車輛的行駿速度 未滿上述一定速度的時間點立即進行，而如果在車輛的行 駛速度未滿上述一定速度的狀態下且在進行鎖定解除指令 的輸入操作時如果解除上述供電的話，就可以防止鎖定操 作者（例如：車掌）無意之間解除了鎖定的情形。 本發明，是包含有：會切換到將車輛用門鎖定在完全 關閉位置的鎖定位置與從該鎖定位置退開而解放上述車輛 用門的非鎖定位置的鎖定切換構件、用來將該鎖定切換構 件朝向上述鎖定位置側彈壓的彈簧構件、以及藉由從電源 本紙張尺度適用中國國家標準（CNS )

的行駛速度是否在一定的速度以上的速度檢測手段、以及 當檢測出車輛的行駿速度在一定的速度以上時則阻止從上 述電源對電磁驅動裝置的供電，而不管上述指令的輸入如 何，會將上述鎖定切換構件保持在鎖定位置之鎖定保持手 段。 經濟部智慧財產局員工消費合作社印製 藉由追種裝置’在車輛的行駿速度未滿一定的速度的 安全的狀態下，鎖定保持手段不會作動，藉由鎖定控制手 段的控制，會根據從外部所輸入的指令來導通或切斷從上 述電源到電磁驅動裝置的電源供給。也就是說，會進行鎖 定的切換。相對的，如果檢測出車輛的行駛速度在上述一 定速度以上的話，鎖定保持手段會阻止從上述電源對電磁 驅動裝置的供電，所以不論上述的指令輸入如何，上述鎖 定切換構件也會被保持在鎖定位置。於是，就可確實地防 止在車輛行駛中誤將門的鎖定解除這樣的情形。 並且，作成具備有：用來進行鎖定解除指令的輸入操 作的指令輸入開關、以及在車輛的行駿速度未滿上述一定 速度的狀態下進行上述指令輸入開關的輸入操作時，會使 上述供電的阻止動作解除的鎖定保持解除手段的話，就可 回復到可根據鎖定操作者（例如車掌）的意思來切換鎖定的狀 本紙張尺度適用中國國家標準（CNS ) A4規格（210X297公釐） 1221816 A7 B7 五、發明説明（5 ) 態’並且可防止在上述鎖定操作者的無意之間將鎖定解除 的情況。 (請先閱讀背面之注意事項再填寫本頁) 用來禁止上述供電的動作，雖然也可藉由例如微電腦 的程式來進行，而如果是作成，具備有：當車輛的行駛速 度在一定速度以上時會斷開，車輛的行駛速度未滿一定速 度時會接通的車速檢測開關，當該車速檢測開關斷開時則 不能從上述電源對電磁驅動裝置進行供電，是把該車速檢 測開關組裝在上述電磁驅動裝置的供電電路，可以將該車 速檢測開關兼用於車速檢測手段與鎖定保持手段，以簡單 的構造就可以確實地進行車輛行駛時的供電阻止動作。 例如，如果讓上述車速檢測開關中介於上述電源與電 磁驅動裝置之間的話，藉由讓同樣的開關斷開就可以確實 地阻止對電磁驅動的供電。 經濟部智慧財產局員工消費合作社印製 在這種情況，如果作成具備有：用來進行鎖定解除指 令的輸入操作的指令輸入開關、與上述車速檢測開關串聯 設置的開閉開關、以及僅當進行上述指令輸入開關的輸入 操作時會使上述開閉開關接通的開關驅動手段，只有由於 行駛速度很低而上述車速檢測開關接通，開閉開關才會斷 開，所以不會解除對電磁驅動裝置的阻止供電，除此之外 ，由於僅當藉由上述指令輸入開關的輸入操作讓上述開閉 開關接通時會解除上述的阻止供電，所以可以防止上述鎖 定操作者在無意之間解除鎖定的情形。 也就是說，上述開閉開關及開關驅動手段，是構成僅 當在車輛的行駿速度未滿上述一定速度的狀態下進行上述

全關閉位置朝向開啓方向移動而朝第3圖的左邊移動（同圖 的兩點虛線）。而且當上述拉門1 0位在上述完全關閉位置 的附近區域時（當卡合銷栓1 8位在第3圖的實線位置與兩 點虛線位置之間的區域時），該卡合銷栓1 8實際上會伸入 上述卡合溝3 6 c內（也就是可以卡合）。 並且，是把上述卡合溝36c及兩叉部36a、 經濟部智慧財產局員工消費合作社印製 3 6 b的形狀設定成，在該卡合狀態下，伴隨著拉門1 〇 的開閉移動（也就是卡合銷栓1 8水平移動），讓轉動構件 3 6在支軸3 4周圍轉動。於是，轉動構件3 6，在拉門 1 0完全關閉的狀態下，是位在第3圖所示的實線的轉動 角度位置（直立位置），會從該位置伴隨著拉門1 〇的開啓而 朝第3圖的順時鐘方向轉動到第3圖的兩點虛線所示的轉 動角度位置（卡合銷栓1 8從卡合溝3 6 c脫離的傾斜位置） 〇 在上述安裝板3 2，在偏離於上述支軸3 4的部位（在

切線方向（在圖例中是水平方向）的延長線L (第3圖的一點 虛線）上，在該狀態下的鎖定臂4 0的位置（第3圖實線所示 的位置）是相當於本發明所謂的「完全關閉對應位置」。也 本紙張尺度適用中國國家標準（CNS ) Α4規格（210Χ297公釐） 1221816 A7 B7 五、發明説明（1〇 ) (請先閱讀背面之注意事項再填寫本頁) 就是說，在該完全關閉對應位置中，鎖定臂4 〇會中介在 轉動構件3 6的抵接面3 6 g與支軸3 8之間而阻止轉動 構件3 6朝向開啓拉門的方向（第3圖的順時鐘方向）轉動。 雖然上述鎖定臂4 0會由於本身的重量及螺旋線圈彈 簧4 4的彈力而被彈壓向第3圖的逆時鐘旋轉方向（卡合用 滾子4 8下降的方向），而轉動構件3 6到達到第3圖所示 的兩點虛線的傾斜位置的話，卡合用滾子4 8會被夾在該 轉動構件3 6的兩叉部3 6 d、3 6 f之間，而讓卡合用 滾子4 8不能再繼續下降（鎖定臂4 0不能朝第3圖的逆時 鐘方向轉動）。 也就是說，該傾斜位置會成爲轉動構件3 6的移動限 制位置。而且，在該傾斜位置，轉動構件3 6的卡合溝 3 6 c是朝斜下方開放，該卡合溝3 6 c是可讓上述拉門 1 0側的卡合銷栓1 8進入，而設定了轉動構件3 6的形 狀。 經濟部智慧財產局員工消費合作社印製 該鎖定組件3 0，是具備有鎖定切換機構5 0，該鎖 定切換機構5

In this fully closed position, the support shaft 38 is located on the extension line L in the direction of the tangential rotation of the rotating member 36 at the abutment point p, and the lock arm 40 is located at a so-called dead point. Even if the elastic force of the elastic material 11 of the sliding door 10 is regarded as a reaction force (the reaction force in the door opening direction) T acts on the lock arm 40 from the above-mentioned contact point P, the reaction force T does not act to make the lock arm The force of 40 rotation is specifically used as a compression load to lock the paper size of the paper. The CNS A4 specification (21GX297 mm) ~ --- 1221816 A7 B7 V. Description of the invention (21) Arm 40. In other words, the reaction force T is supported on the support shaft 38 side using the lock arm 40 as a medium. (Please read the precautions on the back before filling this page) After moving the sliding door 10 to the fully closed position, this time reduce the duty ratio of the door drive signal to 4% to reduce the door closing drive force to lower than usual drive The weak driving force maintains the driving force, and at the same time, the timer built into the control device starts to operate. As a result of the reduction of the driving force for closing the door, printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, the reaction force T transmitted from the rotating member 36 to the locking arm 40 will decrease as shown in FIG. Corresponding position of the fully closed position, at which point the lock switch pin 5 6 is still in the non-locked position, so for example, when foreign objects such as clothes are caught between the sliding doors 10 in the fully closed position, as long as it is manually operated If a force in the opening direction is applied to the sliding door 10, it will be assisted by the elastic force of the coiled wire spring 44, and the rotating member 36 and the locking arm 40 can be rotated in the opposite direction as described above. Open the sliding door 10, so that the foreign matter can be released. When the door closing switch 15 is switched to the cut-off state, the switch driving control means 20 judges to perform an emergency opening operation, and drives the sliding door 10 in a direction to be opened for a predetermined time. On the other hand, after the closing driving force is reduced to F 2, the door opening operation is not performed. When the door closing switch 15 is in the on state and the timer expires (in the illustration, 0 elapses from the time when the driving force is reduced). 5 seconds), increase the duty cycle of the door drive signal to 30% to push the two sliding doors 10 to the fully closed position, and at the same time, switch the transistor 8 2 to the off state to turn the solenoid The coil 54 is turned off (time T 8). In this way, by adapting the paper size of the spiral paper to the Chinese National Standard (CNS) A4 specification (210X297 mm) 1221816 Μ ___ B7 V. Description of the invention (22) (Please read the precautions on the back before filling this page) Tube coil When the electromagnetic driving force of 5 4 disappears, the lock switching pin 5 6 will protrude from the previous unlocked position to the locked position shown by the solid lines in FIGS. 4 and 5 due to the elastic force of the coiled wire spring 5 3. With the presence of the lock switch pin 56, the lock arm 40 cannot be deviated from the above-mentioned fully closed corresponding position, whereby the sliding door 10 connected to the lock arm 40 through the rotating member 36 can Locked in the fully closed position described above. After detecting such a lock operation by the lock detection switch 68, the duty ratio of the door drive signal is adjusted to 0% (that is, the power to the motor 22 is turned off), and the drive is closed. Then, when the vehicle starts and its traveling speed is above a certain speed, the speed detection switch 81 will be turned off and the power supply from the DC power source 80 to the solenoid 圏 54 will be forcibly blocked again. At the same time, the line RC1 of the relay r 1 will also be de-energized. The contact RS1 and the contact rsI will break. Although the action shown above is the operation when the door open command switch 76 is operated, the unlock switch 7 is operated together. The basic lock action at 8 o'clock will not change. Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs, which means that when the car speed is above a certain speed, the speed detection switch 8 1 will be turned off, so even if the unlock switch 7 8 is operated by mistake, In the on state, the solenoid coil 54 will not be energized, and it is possible to surely prevent the lock from being released in fr. In contrast, when the speed of the vehicle under review is stopped or not stopped, the speed detection switch 8 1 will be turned on. In this state, if the uniform unlocking switch 7 8 is switched to the on state, the relay R 3 The coil R c 3 will be energized so that the paper size applies to the Chinese National Standard (CNS) A4 specification (210X297 male ~~ -25- 1221816 A7 B7 V. Description of the invention (23) (Please read the precautions on the back before filling this page ) The point RS 3 is turned on, the coil R 1 of the relay R 1 will be energized and the contacts RS 1, RS 1 > will be turned off, and the control signal will be input from the control device 7 0 to the transistor 8 2 and let the same transistor 8 2 is switched to the ON state 'The solenoid 圏 5 4 will be energized and unlocked. Simultaneously operate both the cut-off open command switch 7 6 and the unified unlock switch 7 8 (that is, the relay coils RC 2 and RC 3 are de-energized). In the state), even if the speed of Xingjun falls below a certain speed and the speed detection switch 8 1 is turned on, the solenoid coil 5 4 will not be energized (that is, unlocked) at this time. Contact RS 2, RS 3. RS 1 is disconnected in order not to let When the electrical coil RC 1 is energized, the relay contact RS 1 / is turned off. In other words, when the vehicle speed detection switch 8 1 is on, one of the switches 7 6 and 7 8 is operated to be turned on and the blocking will be released. Power is supplied to the solenoid coil 54. Therefore, it is possible to reliably prevent the lock operator such as the palm of the car from inadvertently switching the solenoid coil 54 to the ON state (unlocking). Consumption by employees of the Intellectual Property Bureau of the Ministry of Economic Affairs The invention printed by the cooperative is not limited to the above embodiment, and can also be used as the following embodiment as an example. In the above embodiment, the door opening command switch 76 is provided as a command input switch and the lock is unlocked together. For the two switches of the switch 78, only one of the switches may be used as the command input switch. When the door open command switch 76 is used as the command input switch, after the switch 7 is switched to the on state, it is appropriate It is better to set the timing or period for unlocking. For example, you can often apply the coil size to the Chinese country during the door opening and closing process. Standard (CNS) A4 specification (210X297 mm) 1221816 A7 _ B7 V. Description of the invention (24) 5 4 Keep the continuity.
