Description
本發明是與電動自行車有關，特別是指一種經油壓剎車作用下提供一輸出訊號，以該輸出訊號停止電動馬達運轉、停止電源輸出或觸發警示燈(聲響)等用途。 The invention relates to an electric bicycle, in particular to an output signal provided by an oil pressure brake, and the output signal stops the operation of the electric motor, stops the power output or triggers a warning light (sound).
為了方便生活和工作的出行，很多人都選擇將電動自行車作為自己短距離出行的代步工具，而電動自行車作為一種節能環保的交通工具，也得到了社會的廣泛認可。 In order to facilitate the travel of life and work, many people choose to use electric bicycles as a means of transportation for their short-distance travel. As an energy-saving and environmentally-friendly vehicle, electric bicycles have also been widely recognized by the society.
前述的電動自行車一般被稱為電動車或電動腳踏車，是一種以蓄電池為主要能源的交通工具。外觀與自行車或摩托車相似，自行車帶有動力來源的一種，大部分車種還保留自行車的踏板、鏈條，可以用人力作為輔助動力(稱為電動輔助自行車)。而電動自行車其主要動力來源主要是透過其電機驅動，電機主要採用有刷直流電機驅動系統和無刷直流電機驅動系統。對於電機運轉轉速則是採用控制器，又主要利用霍爾傳感器來控制電機轉速的一個重要部件，一般具備無級別調速、過電流保護等功能。關於電動自行車的剎車則是有如摩托車抱剎或碟剎系統來降低行駛速度甚至剎停等需求。 The aforementioned electric bicycle is generally called an electric vehicle or an electric bicycle, and is a vehicle that uses a battery as a main energy source. The appearance is similar to that of a bicycle or a motorcycle. The bicycle has a power source. Most of the models also retain the pedals and chains of the bicycle, and human power can be used as an auxiliary power (called a power-assisted bicycle). The main source of power for electric bicycles is mainly driven by their motors. The motors mainly use brushed DC motor drive systems and brushless DC motor drive systems. For the motor running speed, it is a controller that uses the Hall sensor to control the motor speed. It generally has functions such as levelless speed regulation and overcurrent protection. The brakes on electric bicycles are like motorcycle brakes or disc brake systems to reduce the speed of travel or even stop.
一般電動自行車啟動電門(開關)後，後續操作只 須轉動變速把手，並以變速把手轉動角度幅度控制電機之輸出動力，進而驅使電動自行車行進。關於電動自行車的剎車時，需先切斷電機導通電源，令電動自行車失去動力情況下，在進行剎車動作。然而，在行車情況緊急、不熟操作駕駛者，往往都是轉動變速把手同時按壓剎車把手，造成一邊剎車一邊驅動的狀況，此舉將駕駛與車輛帶入危險事故因子。 After the electric bicycle starts the electric switch (switch), the subsequent operation only The shifting handle must be rotated and the output power of the motor controlled by the angular amplitude of the shifting handle to drive the electric bicycle. When braking the electric bicycle, it is necessary to cut off the power supply of the motor to brake the electric bicycle. However, in the case of emergency driving and unfamiliar driving, the driver often turns the shifting handle while pressing the brake handle, causing the brake to be driven while driving, and driving the vehicle into a dangerous accident factor.
為了改善前述狀況，因此有相關業者開發了安裝於剎車把手內的電控開關，可以在駕駛扣押剎車把手動作的同時切斷電機的電源。但是此種方式將會限定剎車把手的結構、型態，同時增加了剎車把手加工製造與組裝困擾，更大幅度增加成本。 In order to improve the above situation, some related companies have developed an electric control switch installed in the brake handle, which can cut off the power of the motor while driving the brake lever. However, this method will limit the structure and type of the brake handle, and at the same time increase the manufacturing and assembly troubles of the brake handle, and greatly increase the cost.

關於本發明油壓剎車訊號傳輸器其作動方式，再請配合參閱圖式第三、四圖所示，當剎車作用時油液由入口11朝側口13、出口12兩各方向大量移動，由出口12方向流動的剎車油液則驅動剎車卡鉗夾器作動達到進低車速或停止車輛之需求，而由側口13方向流動的剎車油液則推送活塞2並受力集中於活塞2的油推面21，讓活塞2朝大螺孔131方向移動，同時活塞2壓縮外彈簧62、抵盤34壓縮內彈簧63，且活塞2以頂抵面22推抵該受抵面31，讓抵盤34、穿軸332、凸盤部331都能同方向位移(如圖是第四圖所示皆向左側方向位移)，更讓凸盤部331的導電面32接觸訊號接 腳4，如此該訊號接腳4與導電面32電性導通形成迴路，如此得以讓通電訊號經其中一訊號接腳4、導電面32、再由另一訊號接腳4輸出。當剎車作用解除時，得以由剎車油液壓力降低暫時不再流向側口13與出口12，此時即可由內彈簧63與外彈簧62彈性恢復並分別推抵穿動件3、活塞2復位。 Regarding the operation mode of the hydraulic brake signal transmitter of the present invention, please refer to the third and fourth figures of the drawing. When the brake acts, the oil moves from the inlet 11 to the side port 13 and the outlet 12 in a large amount. The brake fluid flowing in the direction of the outlet 12 drives the brake caliper to act to lower the vehicle speed or stop the vehicle, and the brake fluid flowing in the direction of the side port 13 pushes the piston 2 and is concentrated on the oil of the piston 2 The surface 21 moves the piston 2 toward the large screw hole 131, and the piston 2 compresses the outer spring 62, the abutting disk 34 compresses the inner spring 63, and the piston 2 pushes against the abutting surface 31 with the abutting surface 22, so that the abutting plate 34 The through shaft 332 and the convex portion 331 can be displaced in the same direction (as shown in the fourth figure, both are displaced to the left direction), and the conductive surface 32 of the convex portion 331 is contacted with the signal. The foot 4 is so that the signal pin 4 and the conductive surface 32 are electrically connected to form a loop, so that the power signal is outputted through one of the signal pins 4, the conductive surface 32, and the other signal pin 4. When the braking action is released, the brake fluid pressure is reduced and temporarily no longer flows to the side port 13 and the outlet port 12. At this time, the inner spring 63 and the outer spring 62 are elastically restored and respectively pushed against the piercer 3 and the piston 2 is reset.
相信經由上述說明可知，本發明在上述作動下，其能輸出控制訊號，如此能透過該訊號切斷電機(圖未繪製)的電源供應，使得電機不再具備電力而停止轉動。就算駕駛持需轉動變速把手、或車禍撞損變速把手情況下，可以藉由本發明號傳輸器輸出訊號，切段電源導通電機之運轉狀態，也不會造成一邊剎車同時一邊電機運轉，提供安全駕駛者。據此達成本發明之目的與功效者。 It is believed that, according to the above description, the present invention can output a control signal by the above operation, so that the power supply of the motor (not shown) can be cut off by the signal, so that the motor no longer has electric power and stops rotating. Even if the driver needs to rotate the shifting handle, or the vehicle damages the shifting handle, the signal can be outputted by the transmitter of the invention, and the power of the cut-off power supply is turned on, and the motor is not operated while the brake is being operated, thereby providing safe driving. By. Accordingly, the object and effect of the present invention are achieved.
