具體而言，如第1圖至第3圖所示，在本發明的實施例的自行車氣壓助力設備100中，該傳動軸組件1係設置為取代該自行車B原有的中軸，並且具有比該自行車B之中軸更多的功能。該傳動軸組件1能夠與該自行車B之左曲柄C1及右曲柄C2連動，以及藉由該傳動軸組件1之旋轉能夠間接帶動該自行車B之車輪旋轉而使該自行車B前進。Specifically, as shown in FIGS. 1 to 3, in the bicycle pneumatic assist device 100 according to the embodiment of the present invention, the transmission shaft assembly 1 is arranged to replace the original center shaft of the bicycle B, and has a larger Bicycle B has more functions in the middle axle. The transmission shaft assembly 1 can be linked with the left crank C1 and the right crank C2 of the bicycle B, and the rotation of the transmission shaft assembly 1 can indirectly drive the wheels of the bicycle B to rotate to make the bicycle B move forward.

如第1圖至第3圖所示，在本發明的實施例的自行車氣壓助力設備100中，該傳動軸組件1包括曲柄套軸11、傳動轉軸12及單向傳動機構13，該曲柄套軸11用於組接於該自行車B之左曲柄C1及右曲柄C2，該曲柄套軸11經由該單向傳動機構13而單向傳動地組接於該傳動轉軸12，以使該自行車B之左曲柄C1及右曲柄C2僅在正向旋轉方向上帶動該傳動轉軸12旋轉。亦即，該自行車B之左曲柄C1及右曲柄C2在逆向旋轉方向上無法帶動該傳動轉軸12旋轉。As shown in FIGS. 1 to 3, in the bicycle pneumatic assist device 100 according to the embodiment of the present invention, the transmission shaft assembly 1 includes a crank sleeve shaft 11, a transmission rotating shaft 12 and a one-way transmission mechanism 13. The crank sleeve shaft 11 is used to be assembled with the left crank C1 and the right crank C2 of the bicycle B. The crank sleeve 11 is unidirectionally connected to the transmission shaft 12 through the one-way transmission mechanism 13, so that the left side of the bicycle B is The crank C1 and the right crank C2 only drive the transmission shaft 12 to rotate in the forward rotation direction. That is, the left crank C1 and the right crank C2 of the bicycle B cannot drive the transmission shaft 12 to rotate in the reverse rotation direction.

具體而言，如第2圖所示，該曲柄套軸11包括左曲柄套軸及右曲柄套軸，分別經由該單向傳動機構13而組接在該傳動轉軸12之左右二端。該曲柄套軸11較佳地可為非圓形（例：矩形等多邊形）套軸，而能夠以不相對旋轉滑移的方式組接於該自行車B之左曲柄C1及右曲柄C2，以隨著該自行車B之左曲柄C1及右曲柄C2之旋轉（例：藉由踏板踩踏）而一同旋轉。當然，本發明並不限於此，該曲柄套軸11亦能夠為圓形套軸，而利用其它的附加零件（例：鎖固件）來達到與該自行車B之左曲柄C1及右曲柄C2一同旋轉的效果。如第3圖所示，該傳動轉軸12為曲軸，經由連桿而連接至該左充壓活塞氣缸組31a之活塞、該右充壓活塞氣缸組31b之活塞、及該補壓活塞氣缸組之活塞。藉此，該左充壓活塞氣缸組31a及該右充壓活塞氣缸組31b的直線往復運動（包含壓縮行程及膨脹行程）的動能會轉化為該傳動轉軸12的旋轉動能。因此，當進氣至該左充壓活塞氣缸組31a之氣缸或是該右充壓活塞氣缸組31b之氣缸時，該左充壓活塞氣缸組31a或該右充壓活塞氣缸組31b則會進行膨脹行程，使該左充壓活塞氣缸組31a之活塞或該右充壓活塞氣缸組31b之活塞朝向下死點移動，帶動該傳動轉軸12正向旋轉。另一方面，該傳動轉軸12的旋轉運動也能夠帶動該左充壓活塞氣缸組31a之活塞、該右充壓活塞氣缸組31b之活塞、及補壓活塞氣缸組之活塞，而進行直線往復運動。因此，藉由該傳動轉軸12在特定的角度範圍旋轉，也能夠帶動該左充壓活塞氣缸組31a、該右充壓活塞氣缸組31b及／或補壓活塞氣缸組進行壓縮行程，於氣缸內產生壓縮氣體。如第2圖所示，該單向傳動機構13在本實施例中為棘輪軸承，藉由其單向旋轉特性，能夠在該自行車B為反轉踩踏時，使該傳動轉軸12不受該自行車B之左曲柄C1及右曲柄C2帶動，確保該傳動轉軸12保持在正向旋轉方向上旋轉。當然，本發明並不限於此，該單向傳動機構13亦可為單向軸承或其他機構。Specifically, as shown in FIG. 2 , the crank sleeve shaft 11 includes a left crank sleeve shaft and a right crank sleeve shaft, which are respectively assembled on the left and right ends of the transmission shaft 12 via the one-way transmission mechanism 13 . The crank sleeve shaft 11 is preferably a non-circular (eg, rectangular and other polygonal) sleeve shaft, and can be assembled to the left crank C1 and the right crank C2 of the bicycle B in a manner of non-relative rotation and sliding, so as to follow the It rotates together with the rotation of the left crank C1 and the right crank C2 of the bicycle B (eg, by pedaling). Of course, the present invention is not limited to this, the crank sleeve shaft 11 can also be a circular sleeve shaft, and use other additional parts (eg, locks) to achieve the same rotation with the left crank C1 and the right crank C2 of the bicycle B Effect. As shown in FIG. 3, the transmission shaft 12 is a crankshaft, which is connected to the piston of the left charging piston-cylinder group 31a, the piston of the right charging piston-cylinder group 31b, and the compensating piston-cylinder group via connecting rods. piston. Thereby, the kinetic energy of the linear reciprocating motion (including the compression stroke and the expansion stroke) of the left charging piston-cylinder group 31 a and the right charging piston-cylinder group 31 b is converted into the rotational kinetic energy of the transmission shaft 12 . Therefore, when intake air enters the cylinder of the left charging piston-cylinder group 31a or the cylinder of the right charging piston-cylinder group 31b, the left charging piston-cylinder group 31a or the right charging piston-cylinder group 31b will During the expansion stroke, the piston of the left charging piston-cylinder group 31a or the piston of the right charging piston-cylinder group 31b moves toward the bottom dead center, driving the transmission shaft 12 to rotate in the forward direction. On the other hand, the rotational movement of the transmission shaft 12 can also drive the piston of the left charging piston-cylinder group 31a, the piston of the right charging piston-cylinder group 31b, and the piston of the supplementary piston-cylinder group to perform linear reciprocating motion . Therefore, by the rotation of the transmission shaft 12 within a specific angle range, the left charging piston-cylinder group 31a, the right charging piston-cylinder group 31b and/or the supplementary pressure piston-cylinder group can also be driven to perform a compression stroke, in the cylinder Produces compressed gas. As shown in FIG. 2, the one-way transmission mechanism 13 is a ratchet bearing in this embodiment. With its one-way rotation characteristic, when the bicycle B is pedaling in reverse, the transmission shaft 12 can be free from the bicycle. The left crank C1 and the right crank C2 of B are driven to ensure that the transmission shaft 12 keeps rotating in the forward rotation direction. Of course, the present invention is not limited to this, and the one-way transmission mechanism 13 can also be a one-way bearing or other mechanisms.

The rotation angle range of the force application refers to the angle range of 120 degrees when the left crank C1 or the right crank C2 of the bicycle B rotates from the center of rotation (center axis) from the top to the front and the bottom, and the inertia rotation angle range is the remaining 240 degrees. angular range. In the case of a general bicycle, each foot of the rider needs to apply force to the pedal only when it enters the range of the force-applying rotation angle, and does not need to apply force when the pedal rotates within the inertial rotation angle range.
