[0043] See Figures 3 to 6 A first embodiment of the motorcycle of the present invention includes a front wheel (not shown), a rear wheel (not shown), a frame unit 2, a power unit 3, a rear swing arm (not shown), an electric generator 4, an air filter unit 5, an engine control unit (ECU) 6, an electric generator controller 7, a body cover 8, and a storage box 9.
[0044] In the first embodiment, the frame unit 2 includes two main frames 21 located on either side of a frame center plane C, and two sub-frames 22 corresponding to the main frames 21. Each sub-frame 22 is disposed on the lower surface of the rear half of the corresponding main frame 21 and is generally U-shaped. Together with the corresponding main frame 21, they define a receiving space 20.
[0045] like Figure 3 As shown, the power unit 3 is mounted on the vehicle frame unit 2 and includes an engine 31 and an ignition unit 32. The ignition unit 32 includes a spark plug 321 and an ignition coil 322. In this first embodiment, the engine 31 is fixed to the vehicle frame unit 2. This prevents the engine 31 from swinging with the rear swingarm, thereby improving the durability of the wiring harnesses for the engine control unit 6 and the starter generator controller 7.
[0046] The starter generator 4 is mounted on the power unit 3 and has the functions of both a starter motor and a generator.
[0047] The engine control unit 6 is used to control the power unit 3 and is located on one side of the air filter unit 5 and is disposed in one of the accommodating spaces 20. The starter generator controller 7 is used to control the starter generator 4 and is located on the other side of the air filter unit 5.
[0048] In this first embodiment, the engine control unit 6 is located in the left accommodating space 20, while the starter-generator controller 7 is located in the right accommodating space 20. Therefore, since the wiring harnesses (not shown) for the engine control unit 6 and the starter-generator controller 7 are located at the rear of the motorcycle, excessive wiring harness lengths are avoided. Furthermore, since the wiring harnesses for the engine control unit 6 and the starter-generator controller 7 are evenly distributed on both sides of the rear half of the frame unit 2, the problem of increased vehicle width due to wiring harness placement, which would otherwise occur if the engine control unit 6 and the starter-generator controller 7 were concentrated on the same side of the frame unit 2, is further avoided.
[0049] like Figure 5 、 6 As shown, in this first embodiment, the air filter unit 5 is mounted on the frame unit 2, located forward of the storage box 9, and straddles a frame center plane C. Therefore, compared to conventional side-mounted air filter units that occupy space on a single side of the vehicle body, the air filter unit 5 of the present invention, straddling both sides of the frame center plane C, allows the wiring harnesses for the engine control unit 6 and the starter generator controller 7 to be evenly distributed on both sides of the rear half of the frame unit 2. This avoids the disadvantage of conventional side-mounted air filter units that result in wiring harnesses being concentrated on a single side of the vehicle body, thereby increasing vehicle width.
[0050] like Figure 3 、 4 As shown in FIG. 6 , in the first embodiment, the body cover 8 covers the sub-frames 22 , the engine control unit 6 , and the starter generator controller 7 , thereby protecting the wiring harnesses of the engine control unit 6 and the starter generator controller 7 from being damaged by being hit by gravel rolled up from below or the rear.
[0051] In the first embodiment, the storage box 9 is disposed on the vehicle frame unit 2 and located between the engine control unit 6 and the starter generator controller 7 , so that the storage space of the storage box 9 can be maximized.
[0052] See Figure 7 The only difference between a second embodiment of the motorcycle of the present invention and the first embodiment is that, in the second embodiment, the engine control unit 6 is disposed behind the accommodating space 20 on the left.
[0053] In summary, the motorcycle of the present invention has at least the following advantages and effects: (a) Compared with the conventional side-mounted air filter unit that occupies the space on a single side of the vehicle body, the air filter unit 5 of the motorcycle of the present invention spans across both sides of the center plane C of the frame. Therefore, the wiring harnesses of the engine control unit 6 and the starter generator controller 7 can be evenly distributed on both sides of the rear half of the frame unit 2, thereby avoiding the disadvantage of the conventional side-mounted air filter unit that causes the wiring harnesses to be concentrated on the same side of the vehicle body and the resulting increase in vehicle width; (b) The body cover 8 covers the subframes 22, the engine control unit 6, and the starter generator controller 7. 6, and the starter generator controller 7, thereby protecting the wiring harness of the engine control unit 6 and the starter generator controller 7 from being damaged by being hit by gravel rolled up from below or the rear; (c) the engine 31 is a locked engine, thereby preventing the engine 31 from swinging with the rear swing arm, so that the wiring harness of the engine control unit 6 and the starter generator controller 7 has better durability; (d) the storage box 9 is located between the engine control unit 6 and the starter generator controller 7, so that the storage space of the storage box 9 can be maximized; therefore, the purpose of the present invention can be achieved.
[0054] The above descriptions are merely embodiments of the present invention and are not intended to limit the scope of the present invention. Any simple equivalent changes and modifications made in accordance with the claims and description of the present invention are still within the scope of the present invention.
