In addition, the central axis A1 of the output shaft 302 is perpendicular to and intersects with the central axis A2 of the first rod body 131 of the connecting rod 13 . The driver 301 is connected to the output shaft 302 through these transmission gears 306, and the driver 301 is used to drive the output shaft 302 to rotate relative to the base 3041 and the cylinder 11 through these transmission gears 306.

二凸輪303位於缸體11的容置凹槽115內，並固定於輸出軸302。二凸輪303分別位於第一桿體131的相對二側，且抵靠於第一桿體131的環形凸緣1313。The two cams 303 are located in the receiving groove 115 of the cylinder 11 and fixed on the output shaft 302 . The two cams 303 are respectively located on two opposite sides of the first rod body 131 and abut against the annular flange 1313 of the first rod body 131 .

在本實施例中，二軸承307、二凸輪303及第一桿體131中任相鄰的二者之間設有套設於輸出軸302的一個墊圈308。藉此，確保二凸輪303的轉動順暢度。In this embodiment, a washer 308 sleeved on the output shaft 302 is disposed between any two adjacent ones of the two bearings 307 , the two cams 303 and the first rod 131 . Thereby, the smooth rotation of the second cam 303 is ensured.

控制電路板309、編碼器310及無線通訊器311設置於外殼304的容置空間3043內。控制電路板309電性連接於驅動器301。編碼器310電性連接於控制電路板309，並對應於輸出軸302。編碼器310用以感測輸出軸302的角位置。無線通訊器311例如設置於控制電路板309上而電性連接於控制電路板309。The control circuit board 309, the encoder 310 and the wireless communicator 311 are arranged in the accommodation space 3043 of the housing 304. The control circuit board 309 is electrically connected to the driver 301 . The encoder 310 is electrically connected to the control circuit board 309 and corresponds to the output shaft 302 . The encoder 310 is used to sense the angular position of the output shaft 302 . For example, the wireless communicator 311 is disposed on the control circuit board 309 and is electrically connected to the control circuit board 309 .

在本實施例中，控制電路板309例如可具有二電連接器3091、3092。電連接器3091例如用以連接一電池4，電池4提供控制電路板309、驅動器301、編碼器310及無線通訊器311所需的電力。在本實施例中，自行車例如為電動輔助自行車，而電池4不僅為提供驅動組件30所需之電力的電池之外，也是提供電動輔助自行車所需之電力的電池，但並不以此為限。在其他實施例中，電池可為僅提供驅動組件所需之電力的電池，而提供電動輔助自行車所需之電力的電池可為另一個電池。在這樣的配置下，提供驅動組件所需之電力的電池可為可拆卸地設置於驅動組件的外殼內，或者是可拆卸地設置於本體的缸體上。In this embodiment, the control circuit board 309 may have two electrical connectors 3091 and 3092, for example. The electrical connector 3091 is, for example, used to connect a battery 4. The battery 4 provides the power required by the control circuit board 309, the driver 301, the encoder 310 and the wireless communicator 311. In this embodiment, the bicycle is, for example, an electric-assisted bicycle, and the battery 4 is not only a battery that provides the power required by the driving assembly 30, but also a battery that provides the power required by the electric-assisted bicycle, but it is not limited to this. . In other embodiments, the battery may be one that provides only the power needed to drive the assembly, and the battery that provides the power needed for the electrically assisted bicycle may be another battery. In such a configuration, the battery that provides the power required by the driving assembly may be detachably disposed in the housing of the driving assembly, or may be detachably disposed on the cylinder of the body.

在本實施例中，自行車煞車裝置1還可包含一磁鐵60及一感測器70。磁鐵60設置於活塞12上。感測器70例如為磁簧感測器。感測器70設置於缸體11，並電性連接於控制電路板309的電連接器3092。感測器70用以感測活塞12的移動，而透過控制電路板309令無線通訊器311發送一無線訊號。In this embodiment, the bicycle braking device 1 may further include a magnet 60 and a sensor 70 . The magnet 60 is provided on the piston 12 . The sensor 70 is, for example, a magnetic reed sensor. The sensor 70 is disposed on the cylinder 11 and is electrically connected to the electrical connector 3092 of the control circuit board 309 . The sensor 70 is used to sense the movement of the piston 12, and causes the wireless communicator 311 to send a wireless signal through the control circuit board 309.

在本實施例中，活塞12可以手動的方式及電動的方式被致動。以下將先介紹活塞12被手動的方式致動的過程。請先參閱圖6及圖7。圖6為圖4之煞車拉桿被致動後的剖視示意圖。圖7為圖5之煞車拉桿被致動後的剖視示意圖。In this embodiment, the piston 12 can be actuated manually as well as electrically. The process of manually actuating the piston 12 will be introduced below. Please refer to Figure 6 and Figure 7 first. FIG. 6 is a schematic cross-sectional view of the brake lever in FIG. 4 after it is actuated. FIG. 7 is a schematic cross-sectional view of the brake lever in FIG. 5 after it is actuated.

使用者可以按壓煞車拉桿20的拉柄22，而透過第一調整螺絲23帶動搖擺件21的端部212相對缸體11樞轉，使得搖擺件21的端部211透過第二桿體132的推抵部1321推抵第一桿體131的受推部1311，來讓第一桿體131相對輸出軸302移動，進而帶動活塞12朝出油孔114移動，以產生油壓。此油壓經由油管3傳輸至前煞車卡鉗，來對於前輪進行煞車。The user can press the handle 22 of the brake lever 20 and use the first adjustment screw 23 to drive the end 212 of the swing member 21 to pivot relative to the cylinder 11 so that the end 211 of the swing member 21 is pushed by the second rod 132 The resisting portion 1321 pushes against the pushed portion 1311 of the first rod 131 to move the first rod 131 relative to the output shaft 302, thereby driving the piston 12 to move toward the oil outlet hole 114 to generate oil pressure. This oil pressure is transmitted to the front brake caliper through oil pipe 3 to brake the front wheel.

在前述活塞12移動的過程中，感測器70感知活塞12的移動，以透過控制電路板309令無線通訊器311傳遞無線訊號予外部電子裝置(未繪示)。外部電子裝置例如為自行車的中央控制系統，中央控制系統不僅與本實施例的自行車煞車裝置1(右煞車把手組件)無線通訊，還與左煞車把手組件(未繪示)無線通訊。其中，左煞車把手組件可與自行車煞車裝置1例如具有相同或不同的配置。在中央控制系統接收到此無線訊號後，會發送一致動訊號予左煞車把手組件，使左煞車把手組件運作，來致動後煞車卡鉗(未繪示)對於後輪進行煞車，以減少前後輪之間的輪速差。During the movement of the piston 12, the sensor 70 senses the movement of the piston 12 to cause the wireless communicator 311 to transmit a wireless signal to an external electronic device (not shown) through the control circuit board 309. The external electronic device is, for example, a central control system of a bicycle. The central control system not only communicates wirelessly with the bicycle braking device 1 (right brake handle assembly) of this embodiment, but also communicates wirelessly with the left brake handle assembly (not shown). The left brake handle assembly may have the same or different configurations as the bicycle braking device 1 , for example. After the central control system receives this wireless signal, it will send an actuation signal to the left brake handle assembly, causing the left brake handle assembly to operate to activate the rear brake caliper (not shown) to brake the rear wheels to reduce the front and rear wheels. wheel speed difference between.

同理，當左煞車把手組件的煞車拉桿***作時，會驅動左煞車把手組件之缸體內的活塞產生驅動後煞車卡鉗的油壓。此時，左煞車把手組件的無線通訊器因感測器感測到活塞的移動，而會傳遞無線訊號予中央控制系統。接著，中央控制系統據此發送致動訊號予自行車煞車裝置1，使自行車煞車裝置1運作，來致動前煞車卡鉗對於前輪進行煞車，以減少前後輪之間的輪速差。Similarly, when the brake lever of the left brake lever assembly is operated, the piston in the cylinder of the left brake lever assembly is driven to generate oil pressure that drives the rear brake caliper. At this time, the wireless communicator of the left brake handle assembly transmits a wireless signal to the central control system because the sensor senses the movement of the piston. Then, the central control system sends an actuation signal to the bicycle braking device 1 accordingly, causing the bicycle braking device 1 to operate to activate the front brake caliper to brake the front wheel to reduce the wheel speed difference between the front and rear wheels.

詳細來說，請參閱圖8與圖9，圖8為圖4之凸輪推抵第一桿體的剖視示意圖。圖9為圖5之凸輪推抵第一桿體的剖視示意圖。For details, please refer to FIGS. 8 and 9 . FIG. 8 is a schematic cross-sectional view of the cam in FIG. 4 pushing against the first rod body. Figure 9 is a schematic cross-sectional view of the cam in Figure 5 pushing against the first rod body.

當自行車煞車裝置1之驅動組件30的無線通訊器311收到來自中央控制系統的致動訊號時，控制電路板309依據此致動訊號令驅動器301開始運作。驅動器301透過這些傳動齒輪306傳動於輸出軸302，而使輸出軸302與固定於輸出軸302的二凸輪303一同轉動。在二凸輪303轉動的過程中，二凸輪303推抵第一桿體131的環形凸緣1313，而帶動第一桿體131，以使連接於第一桿體131的活塞12移動而產生致動前煞車卡鉗的油壓，並使第一桿體131的受推部1311分離於第二桿體132的推抵部1321。When the wireless communicator 311 of the driving assembly 30 of the bicycle brake device 1 receives an actuation signal from the central control system, the control circuit board 309 starts the operation of the driver 301 according to the actuation signal. The driver 301 is driven to the output shaft 302 through the drive gears 306, so that the output shaft 302 and the two cams 303 fixed to the output shaft 302 rotate together. During the rotation of the second cam 303, the second cam 303 pushes against the annular flange 1313 of the first rod 131, thereby driving the first rod 131 to move the piston 12 connected to the first rod 131 to generate oil pressure for actuating the front brake caliper, and to separate the pushed portion 1311 of the first rod 131 from the pushing portion 1321 of the second rod 132.

如此一來，手動操作二個煞車手把組件之其中一者的煞車拉桿，不僅可致動與***作之煞車把手組件連接的煞車卡鉗之外，還可驅使另一煞車把手組件以電動的方式致動另一煞車卡鉗，來進行輔助煞車。In this way, manually operating the brake lever of one of the two brake handle assemblies can not only actuate the brake caliper connected to the operated brake handle assembly, but also drive the other brake handle assembly in an electric manner. Activate the other brake caliper to provide auxiliary braking.

在本實施例中，藉由驅動組件30之驅動器301連接於輸出軸302，二凸輪303固定於輸出軸302並抵靠於第一桿體131的環形凸緣1313，以及輸出軸302的中心軸線A1垂直並相交於第一桿體131的中心軸線A2的配置，可使第一桿體131被驅動組件30平順地驅動，而帶動活塞12於液壓腔室111內移動，故可確保活塞12能如預期地增加煞車油的壓力。In this embodiment, the driver 301 of the driving assembly 30 is connected to the output shaft 302. The two cams 303 are fixed on the output shaft 302 and abut against the annular flange 1313 of the first rod body 131 and the central axis of the output shaft 302. The arrangement of A1 perpendicular to and intersecting the central axis A2 of the first rod body 131 allows the first rod body 131 to be driven smoothly by the driving assembly 30 and drives the piston 12 to move in the hydraulic chamber 111, thus ensuring that the piston 12 can Increase brake fluid pressure as expected.

此外，在二凸輪303推抵第一桿體131的過程中，二凸輪303推抵第一桿體131的合力(如箭頭F所示)為沿著第一桿體131的中心軸線A2施予第一桿體131，藉此可使得第一桿體131被驅動的順暢度更為提升。In addition, in the process of the two cams 303 pushing against the first rod 131, the resultant force (shown by arrow F) of the two cams 303 pushing against the first rod 131 is exerted along the central axis A2 of the first rod 131. The first rod body 131 can thereby further improve the smoothness with which the first rod body 131 is driven.

應注意的是，凸輪303的數量並不以二個為限。在其他實施例中，驅動組件可僅包含一凸輪。在這樣的配置下，輸出軸可不用穿過第一桿體，而使得第一桿體可不用有穿槽的結構，且第一桿體的凸緣可不用為環形。It should be noted that the number of cams 303 is not limited to two. In other embodiments, the drive assembly may include only a cam. Under such a configuration, the output shaft does not need to pass through the first rod body, so that the first rod body does not need to have a grooved structure, and the flange of the first rod body does not need to be annular.

另一方面，藉由連桿13的第二桿體132之推抵部1321可分離地抵靠於第一桿體131的受推部1311，以及驅動組件30可帶動第一桿體131，而使第一桿體131的受推部1311分離於第二桿體132之推抵部1321的配置，可使第一桿體131在被驅動的過程中不用帶動其他元件(如第二桿體132、搖擺件21及拉柄22)，故可減少所需之驅動器301的輸出力。On the other hand, the pushing portion 1321 of the second rod body 132 of the connecting rod 13 can detachably abut against the pushed portion 1311 of the first rod body 131, and the driving assembly 30 can drive the first rod body 131, and The arrangement of separating the pushed portion 1311 of the first rod 131 from the pushing portion 1321 of the second rod 132 allows the first rod 131 to be driven without driving other components (such as the second rod 132 , swing member 21 and pull handle 22), so the required output force of the driver 301 can be reduced.

此外，第二桿體132之導引部1322是用來在第一桿體131相對第二桿體132移動時導引第一桿體131的受推部1311。但，應注意的是，第二桿體132之導引部1322為選用的結構而可在其他實施例中進行省略。In addition, the guide portion 1322 of the second rod 132 is used to guide the pushed portion 1311 of the first rod 131 when the first rod 131 moves relative to the second rod 132 . However, it should be noted that the guide portion 1322 of the second rod body 132 is an optional structure and can be omitted in other embodiments.

再者，連桿13的第二桿體132之推抵部1321並不限於可分離地抵靠於第一桿體131的受推部1311。若所採用之驅動器的輸出力足夠，則連桿的第二桿體與第一桿體可為一體地相連而不可分離的配置，而使得第一桿體不需要有受推部及第二桿體不需要有推抵部。Furthermore, the pushing portion 1321 of the second rod body 132 of the connecting rod 13 is not limited to the pushed portion 1311 that can detachably abut against the first rod body 131 . If the output force of the driver used is sufficient, the second rod body and the first rod body of the connecting rod can be integrally connected and inseparable, so that the first rod body does not need to have a pushed part and a second rod The body does not need to have a push-up part.

上述之中央控制系統是依據左煞車把手組件之缸體內的活塞的移動才發送致動驅動器301的致動訊號予無線通訊器311，但並不以此為限。在其他實施例中，中央控制系統可依據輪速感測器所感測之後輪的輪速變化過大發送致動驅動器的致動訊號予無線通訊器。The above-mentioned central control system sends the activation signal of the actuator 301 to the wireless communicator 311 based on the movement of the piston in the cylinder of the left brake handle assembly, but is not limited to this. In other embodiments, the central control system may send an actuation signal for the actuator to the wireless communicator based on the excessive change in wheel speed of the rear wheel sensed by the wheel speed sensor.

在本實施例中，控制電路板309與中央控制系統之間是無線通訊，但並不以此為限。在其他實施例中，控制電路板與中央控制系統之間可為有線通訊。舉例來說，中央控制系統可透過電纜電性連接於控制電路板的電連接器。如此，驅動組件可省略無線通訊器，而訊號可透過電纜以有線的方式於中央控制系統與控制電路板之間傳輸，且供給中央控制系統的電力亦可透過電纜提供給控制電路板及與控制電路板電性連接的元件。In this embodiment, the communication between the control circuit board 309 and the central control system is wireless, but it is not limited to this. In other embodiments, wired communication may be used between the control circuit board and the central control system. For example, the central control system can be electrically connected to the electrical connector of the control circuit board through a cable. In this way, the driving component can omit the wireless communicator, and the signal can be transmitted between the central control system and the control circuit board in a wired manner through the cable, and the power supplied to the central control system can also be provided to the control circuit board and control through the cable. Components that are electrically connected to a circuit board.

應注意的是，編碼器310為選配的元件。在其他實施例中，驅動組件可無編碼器。此外，驅動組件30並不限包含有傳動齒輪306。在其他實施例中，驅動組件可無傳動齒輪，而驅動器可直接驅動輸出軸。再者，軸承307及墊圈308亦為選配的元件。在其他實施例中，驅動組件可無軸承及墊圈。It should be noted that the encoder 310 is an optional component. In other embodiments, the drive assembly may be encoderless. In addition, the driving assembly 30 is not limited to including the transmission gear 306 . In other embodiments, the drive assembly may be gearless and the driver may directly drive the output shaft. Furthermore, the bearing 307 and the washer 308 are also optional components. In other embodiments, the drive assembly may be without bearings and washers.

根據上述實施例所揭露的自行車煞車裝置，藉由驅動組件之驅動器連接於輸出軸，二凸輪固定於輸出軸並抵靠於第一桿體的環形凸緣，以及輸出軸的中心軸線垂直並相交於第一桿體的中心軸線的配置，可使第一桿體被驅動組件平順地驅動，而帶動活塞於液壓腔室內移動，故可確保活塞能如預期地增加煞車油的壓力。According to the bicycle braking device disclosed in the above embodiment, the driver of the driving assembly is connected to the output shaft, the two cams are fixed on the output shaft and abut against the annular flange of the first rod body, and the central axes of the output shaft are perpendicular to and intersect with each other. The arrangement on the central axis of the first rod allows the first rod to be smoothly driven by the driving component and drives the piston to move in the hydraulic chamber, thus ensuring that the piston can increase the pressure of the brake oil as expected.

再者，在二凸輪推抵第一桿體的過程中，二凸輪推抵第一桿體的合力為沿著第一桿體的中心軸線施予第一桿體，藉此可使得第一桿體被驅動的順暢度更為提升。Furthermore, in the process of the two cams pushing against the first rod, the resultant force of the two cams pushing against the first rod is applied to the first rod along the central axis of the first rod, thereby making the first rod The smoothness of the body being driven is further improved.

此外，藉由連桿的第二桿體之推抵部可分離地抵靠於第一桿體的受推部，以及驅動組件可帶動第一桿體，而使第一桿體的受推部分離於第二桿體之推抵部的配置，可使第一桿體在被驅動的過程中不用帶動其他元件(如第二桿體、搖擺件及拉柄)，故可減少所需之驅動器的輸出力。In addition, the pushing portion of the second rod body of the connecting rod can detachably abut against the pushed portion of the first rod body, and the driving assembly can drive the first rod body, so that the pushed portion of the first rod body The configuration of the pushing part that is separated from the second rod body allows the first rod body to be driven without driving other components (such as the second rod body, the rocking member and the pull handle), so the required driver can be reduced. output force.
