Moreover, since the second gear set 23 and the first gear set 22 are arranged in opposite directions, only two layers of gear contact surfaces are formed in the reduction gear unit 2, which can shorten the reduction gear unit 2 and the brake disc. The distance of the sheet 9 is more conducive to the miniaturization of the electronic parking device of the present invention.

在本實施例中，該輸出齒輪24被該第二齒輪組23之該第二小齒輪232帶動。 In this embodiment, the output gear 24 is driven by the second pinion 232 of the second gear set 23.

如圖1、3所示，該固定架5用來設置該煞車卡鉗4，且包括至少一固定螺絲孔51，及一容設部52。在本實施例中，該固定 螺絲孔51是介於該齒輪殼體20與該煞車碟片9之中心之間，且是鄰近於該齒輪殼體20之該內陷空間201。在本實施例中，由於是利用鄰近於該齒輪殼體20之該內陷空間201的固定螺絲孔51來將該固定架5安裝至機車(圖未示)，故亦可達到縮小本發明電子駐車裝置之體積之功效。 As shown in FIGS. 1 and 3, the fixing frame 5 is used to set the brake caliper 4, and includes at least one fixing screw hole 51 and an accommodating portion 52. In this embodiment, the fixed The screw hole 51 is located between the center of the gear housing 20 and the brake disc 9 and is adjacent to the recessed space 201 of the gear housing 20. In this embodiment, since the fixing screw hole 51 adjacent to the recessed space 201 of the gear housing 20 is used to install the fixing frame 5 to a locomotive (not shown), it can also be achieved to reduce the size of the electronic device of the present invention. The effect of the volume of the parking device.

在本實施例中，該容設部52之剖面概呈L形且界定一容置空間53，其中，該馬達1之一部分是設置於該容置空間53內，可進一步達到縮小本發明電子駐車裝置之體積之功效。 In this embodiment, the section of the accommodating portion 52 is generally L-shaped and defines an accommodating space 53, wherein a part of the motor 1 is disposed in the accommodating space 53, which can further reduce the size of the electronic parking system of the present invention. The effect of the size of the device.

如圖3所示，該推動單元3包括一調整螺桿31及一調整螺帽32。該調整螺桿31可被該輸出齒輪24帶動而轉動。該調整螺帽32與該調整螺桿31之間是藉由一螺紋部30螺接，且被該調整螺桿31帶動而移動，其中，在本實施例中，該螺紋部30是梯形螺紋，以能提供足夠大的磨擦力道來達到鎖住(Lock)效果，而使該馬達1關電後該調整螺桿31與該調整螺帽32二者之間不會有相對運動。 As shown in FIG. 3, the pushing unit 3 includes an adjusting screw 31 and an adjusting nut 32. The adjusting screw 31 can be driven by the output gear 24 to rotate. The adjusting nut 32 and the adjusting screw 31 are screwed together by a threaded portion 30 and moved by the adjusting screw 31. In this embodiment, the threaded portion 30 is a trapezoidal thread, so as to be able to A sufficient friction force is provided to achieve a locking effect, so that there will be no relative movement between the adjusting screw 31 and the adjusting nut 32 after the motor 1 is turned off.

在本實施例中，由於該推動單元3僅需使用該調整螺桿31及該調整螺帽32，故也能達到零件數較少之效果，而更有利於整體電子駐車裝置之小型化。 In this embodiment, since the pushing unit 3 only needs to use the adjusting screw 31 and the adjusting nut 32, the effect of fewer parts can be achieved, which is more conducive to the miniaturization of the overall electronic parking device.

如圖2、3、5所示，該煞車卡鉗4包括一卡鉗本體40、一活塞41，及二相間隔的煞車來令片42、43。該卡鉗本體40具有一缸孔401，及一與該缸孔401相連通的煞車液通道402。 As shown in FIGS. 2, 3, and 5, the brake caliper 4 includes a caliper body 40, a piston 41, and two brake pads 42 and 43 spaced apart from each other. The caliper body 40 has a cylinder hole 401 and a brake fluid passage 402 communicating with the cylinder hole 401.

該活塞41設置於該缸孔401內，並可被該調整螺帽32推動。在本實施例中，該活塞41具有一用於推動煞車來令片42的推動壁412，及一自該推動壁412朝遠離該等煞車來令片42、43之方向延伸的圍繞壁413，其中，該推動壁412及該圍繞壁413共同界定一容置該調整螺桿31及該調整螺帽32且與該缸孔401相連通的容設空間414。 The piston 41 is disposed in the cylinder hole 401 and can be pushed by the adjusting nut 32. In this embodiment, the piston 41 has a pushing wall 412 for pushing the brake pads 42 and a surrounding wall 413 extending from the pushing wall 412 in a direction away from the brake pads 42, 43, The pushing wall 412 and the surrounding wall 413 jointly define an accommodating space 414 for accommodating the adjusting screw 31 and the adjusting nut 32 and communicating with the cylinder hole 401.

該煞車液通道402與該缸孔401及該容設空間414相連通。 The brake fluid passage 402 communicates with the cylinder hole 401 and the containing space 414.

該等煞車來令片42、43能被該活塞41推動，以夾住該煞車碟片9，而使本發明電子駐車裝置能達成電子駐車功能或液壓煞車功能。 The brake pads 42 and 43 can be pushed by the piston 41 to clamp the brake disc 9 so that the electronic parking device of the present invention can achieve an electronic parking function or a hydraulic brake function.

如圖2、3所示，當機車騎士欲進行電子駐車時，係藉由啟動該馬達1正轉來帶動該減速齒輪單元2轉動，繼而使該調整螺桿31轉動，以推動該調整螺帽32，繼而藉由推動該活塞41之該推動壁412令該活塞41向前，導致該等煞車來令片42、43能被該活塞41推動，因而該等煞車來令片42、43能夾住該煞車碟片9。反之，機車騎士亦可令該馬達1反轉來使該調整螺帽32向後移以鬆掉活塞41，因而該等煞車來令片42、43不再煞住該煞車碟片9。再者，若在該等煞車來令片42、43夾住該煞車碟片9的情況下該馬達1斷電，則由於該螺紋部30是梯形螺紋而能提供足夠大的磨擦力道，故 該調整螺桿31及該調整螺帽31間會自動維持在不會有相對運動之鎖住(Lock)狀態，使得機車仍可自動維持在電子駐車狀態。 As shown in Figures 2 and 3, when the locomotive rider wants to perform electronic parking, the motor 1 is started to rotate forward to drive the reduction gear unit 2 to rotate, and then the adjustment screw 31 is rotated to push the adjustment nut 32 , And then by pushing the pushing wall 412 of the piston 41 to make the piston 41 forward, the brake plates 42, 43 can be pushed by the piston 41, so the brake plates 42, 43 can be clamped The brake disc 9. Conversely, the motorcycle rider can reverse the motor 1 to move the adjusting nut 32 backward to loosen the piston 41, so that the brake discs 42 and 43 no longer brake the brake disc 9. Furthermore, if the motor 1 is powered off when the brake discs 42, 43 clamp the brake disc 9, since the threaded portion 30 is a trapezoidal thread, it can provide a sufficient friction force. The adjusting screw 31 and the adjusting nut 31 are automatically maintained in a locked state without relative movement, so that the locomotive can still be automatically maintained in the electronic parking state.

如圖2、5所示，或者，當機車騎士欲進行液壓煞車時，係藉由操作煞車裝置(圖未示)來使煞車液經由該煞車液通道402注入該容設空間414，以推動該活塞41，因而帶動該等煞車來令片42、43，以令該等煞車來令片42、43夾住該煞車碟片9。 As shown in Figures 2 and 5, or when the motorcycle rider wants to perform hydraulic braking, the brake fluid is injected into the containing space 414 through the brake fluid channel 402 by operating a braking device (not shown) to push the The piston 41 thus drives the brake discs 42 and 43 so that the brake discs 42 and 43 clamp the brake disc 9.

綜上所述，本發明電子駐車裝置之主要優點及功效在於：在該減速齒輪單元2中僅會形成2層的齒輪接觸面，可縮短該減速齒輪單元2與該煞車碟片9的距離，而有利於本發明電子駐車裝置之小型化，並且由於該推動單元3僅需使用該調整螺桿31及該調整螺帽32，故能達到零件數較少之效果，而更有利於整體電子駐車裝置之小型化，所以確實能達成本發明的目的。 In summary, the main advantages and effects of the electronic parking device of the present invention are: only two layers of gear contact surfaces are formed in the reduction gear unit 2, which can shorten the distance between the reduction gear unit 2 and the brake disc 9. It is beneficial to the miniaturization of the electronic parking device of the present invention, and because the pushing unit 3 only needs to use the adjusting screw 31 and the adjusting nut 32, the effect of fewer parts can be achieved, which is more beneficial to the overall electronic parking device The miniaturization can indeed achieve the purpose of the invention.
