As shown in fig. 1, the power unit 20 is disposed inside the motorcycle body 10, and is driven by the power unit 20 to provide power for the motorcycle to travel. Referring to fig. 2, which is a partial cross-sectional view taken along line A-A of fig. 1, fig. 3 is an enlarged partial schematic view of a dashed circle B of fig. 2, and fig. 1 and 6 show that the power unit 20 includes a driving shaft 22, where the driving shaft 22 is used to drive the transmission mechanism 30 to operate. Taking the present embodiment as an example, the power unit 20 may be an engine or a motor, and the power unit 20 of the present embodiment is any power source for a motorcycle.

Referring to fig. 6 in combination with fig. 4 and fig. 7A-F, the transmission mechanism 30 includes a front pulley 32, a rear pulley 34, a belt 36 and a stop member 38, wherein the front pulley 32 is connected to the driving shaft 22 for being driven by the driving shaft 22 to rotate. The front pulley 32 and the rear pulley 34 have a distance therebetween, and the distance in this embodiment refers to the minimum distance between the outer edge of the front pulley 32 and the outer edge of the rear pulley 34, the belt 36 connects the front pulley 32 and the rear pulley 34, the rear pulley 34 is driven to rotate by the transmission of the belt 36 when the front pulley 32 rotates, the rear pulley 34 is connected to the rear wheel 12, and the rear pulley 34 drives the rear wheel 12 to rotate when rotating, so that the motorcycle generates forward power.

Referring to fig. 2 and 3, the belt 36 is oriented outwardly away from the rear wheel and inwardly in the opposite direction. Referring to fig. 5, the belt 36 is partially sleeved on the outer sides of the front pulley 32 and the rear pulley 34, respectively, and the belt 36 has a bare segment 362 between the front pulley 32 and the rear pulley 34 due to the distance between the front pulley 32 and the rear pulley 34. Referring to fig. 3, the stop member 38 includes a positioning post 384 and a stop block 385, the stop block 385 is connected to the positioning post 384 and has a stop surface 382, and the stop surface 382 corresponds to the exposed section 362 and has a distance D1 from a side edge of the exposed section 362, and the stop surface 382 can have a distance D1 from an inner side edge or an outer side edge of the exposed section 362.

When the belt 36 drives the rear pulley 34 to rotate, the belt 36 may slide laterally along the circumferential side of the front pulley 32, especially the outward sliding occurs more frequently, and the stop surface 382 may partially or fully contact the outer edge of the belt 36 to stop the belt 36, so as to prevent the belt 36 from sliding partially or fully out of the front pulley 32, or rub against other components to generate noise or wear, and also has the effect of positioning the position of the belt 36. In addition, the stop surface 382 corresponds to the exposed portion 362, and means that at least a portion of the stop surface 382 contacts the outer edge of the belt 36 or the entire stop surface 382 contacts the outer edge of the belt 36 when the belt 36 slides laterally.

Other embodiments of the present utility model will be described below with reference to the drawings, respectively. First, as shown in fig. 5, the exposed section 362 includes an upper exposed sub-section 3622 and a lower exposed sub-section 3624, and the stop surface 382 may correspond to the upper exposed sub-section 3622 or the lower exposed sub-section 3624, so as to achieve the above-mentioned effects of preventing the belt 36 from excessive sliding and reducing wear. As shown in fig. 5, the rotation direction of the belt 36 is opposite to the clock direction, as can be seen from fig. 5 and 6, when the front pulley 32 drives the rear pulley 34 to rotate, the upper exposed sub-segment 3622 is tensioned to be tight, and the lower exposed sub-segment 3624 is loosened to be loose, so that the lower exposed sub-segment 3624 is easy to loosen, and therefore the stop surface 382 has a better stop effect on the belt 36 corresponding to the outer side edge of the lower exposed sub-segment 3624. In addition, in some embodiments, the belt 36 and the front pulley 32 have a tangent point P3, the belt 36 and the rear pulley 34 have a tangent point P4, a distance L1 is provided between the tangent point P3 and the tangent point P4, and the distance L2 between the stop member 38 and the tangent point P3 is significantly better than when the distance L2 is far smaller than the distance L1, such that the stop surface 382 is adjacent to the front pulley 32. The stop surface 382 also has a locating effect when the belt 36 is wrapped around the front pulley 32 or the rear pulley 34 during assembly of the transmission mechanism 30, so that the belt 36 can be assembled easily.

Referring next to fig. 7A-7F, various embodiments of the stop 38 corresponding to the outer edge of the belt 36 are described below. In the embodiment of fig. 7A, the thickness T1 of the stopper 38 corresponds to the thickness T2 of the belt 36, and the stopper 38 is located slightly higher than the position of the belt 36, so that the stopper surface 382 partially contacts the partial outer edge of the belt 36 to produce a stopping effect. In the embodiment of fig. 7B, the thickness T1 of the stopper 38 corresponds to the thickness T2 of the belt 36, and the position of the stopper 38 is substantially identical to the position of the belt 36. In the embodiment of fig. 7C, the position of the stop 38 is substantially identical to the position of the belt 36, but the thickness T1 of the stop 38 is less than the thickness T2 of the belt 36. Fig. 7B and 7C each show the stop surface 382 entirely contacting the outer edge of the belt 36 to create a stop effect. In the embodiment of fig. 7D, the horizontal position of the stopper 38 is equivalent to the horizontal position of the belt 36, and the thickness T1 of the stopper 38 is greater than the thickness T2 of the belt 36, so that the stopper surface 382 partially contacts the entire outer edge of the belt 36 to produce a stopper effect. Fig. 7E illustrates another embodiment of the belt 36, wherein the belt 36 includes a belt body 364 and a rack 366, and the rack 366 is disposed on one side of the belt body 364, as illustrated in fig. 7E, the rack 366 is disposed on the inner side of the belt body 364 for contacting the front pulley 32 and the rear pulley 34, and in this embodiment, the position of the stop surface 382 is substantially equal to the position of the belt body 364, so that the stop surface 382 has a stop effect on the belt body 364. The correspondence between stop 38 and belt 36 of the embodiment of fig. 7A-7D is applicable to belt body 364 of belt 36 of fig. 7E. Finally, referring to fig. 7F, the stop surface 382 is located on a second imaginary plane P2, the outer edge of the belt 36 is located on a first imaginary plane P1, and the first imaginary plane P1 and the second imaginary plane P2 form an acute angle θ, such that the stop surface 382 partially contacts with a partial outer edge of the belt 36 to generate a stop effect. The acute angle θ is between 0 degrees and 5 degrees and includes 0 degrees and 5 degrees, and as shown in fig. 7F, the opening at the acute angle θ is not limited to be upward, and the opening at the acute angle θ may be downward.

Referring to fig. 4, in another embodiment of the present utility model, a first baffle 322 and a second baffle 324 are circumferentially spaced apart along the front pulley 32, and the belt 36 is located between the first baffle 322 and the second baffle 324, and the first baffle 322 and the second baffle 324 have positioning effects, so that the belt 36 is positioned on the front pulley 32. Referring to fig. 3, in an embodiment, a distance D1 between the stop surface 382 and the belt 36 is 0.1 to 0.5 mm, and referring to fig. 4, a distance D2 between an inner side surface of the second baffle 324 and an outer edge of the belt 36 is greater than the distance D1. Therefore, when the belt 36 slides, the outer edge of the belt 36 is stopped by the stopper 38 and does not collide with the second baffle 324, so that noise generated by friction between the belt 36 and the second baffle 324 can be avoided.

Referring to fig. 6, according to an embodiment, two ends of the rocker arm 40 are respectively connected to the front pulley 32 and the rear pulley 34, the stopper 38 is fixed to the rocker arm 40, and in an embodiment, the stopper 38 is fixed to a bottom surface of the rocker arm 40, such that the stopper 38 corresponds to the lower exposed sub-segment 3624.
