Locomotive with heat conduction and air guiding effect

The invention relates to a locomotive, in particular to a locomotive having a heat-dissipating air guiding effect.

In modern society, locomotives have not only become a universally used means of transportation in daily life, but also the driver's requirements for various performances of locomotives are increasing. Therefore, in addition to improving the appearance of the locomotive to increase the driver's willingness to purchase, the industry is also committed to the modification of the performance and configuration of the various components inside the locomotive, in order to meet the driver's needs for all aspects of the locomotive.

In general, the locomotive is required to introduce outside air when the locomotive is driven. After filtering through the air filter, the clean air and fuel are mixed into oil and gas, and the engine is burned and exploded to generate kinetic energy, thereby pushing the piston to reciprocate. And then drive the wheel to move. Referring to Figure 1, a conventional locomotive 1 is shown. The locomotive 1 includes a vehicle body 11, a casing 12, a power unit 13 (covered by the casing 12), and an air cleaner 14. The vehicle body 11 includes a seat cushion 111 for a driver to ride. The outer casing 12 includes a front trim panel 121, a central cover plate 122 below the seat cushion 111, and two central cover plates 122 respectively disposed on the vehicle body cover 122. The side cover plates 123 on both sides (only one of them is shown in FIG. 1 due to the viewing angle). The central cover 122 has a plurality of central air guiding openings 124, and the side cover plates 123 respectively have a plurality of side air guiding openings 125. The power unit 13 is disposed under the seat cushion 111. The air cleaner 14 is disposed between the power unit 13 and the seat cushion 111, and includes an outer air supply port for the outside air. 125 enters the suction duct 141 in the air cleaner 14.

When the locomotive 1 travels, the outside air enters the central cover plate 122 and the side cover plates 123 from the central air guiding ports 124 and the side air guiding ports 125, and enters the air filter through the air suction pipe 141. In the cleaner 14. After the air is filtered by the air filter 14, it is then mixed into a carburetor (not shown) and mixed with fuel to form oil and gas, thereby providing combustion operation of the power unit 13.

However, due to the speed and the direction of travel, the conventional locomotive 1 may be subjected to the fascia 121 before the outer casing 12 when traveling, and when the outside air collides with the front fascia 121, it is diverted to both sides. When entering the central air vent 124 and the side air vent 125, most of the air has escaped from the surrounding space. In other words, the amount of air that can be used by the power unit 13 in the central cover 122 and the side cover 123 can be entered through the central air vents 124 and the side air vents 125, and initially at the front fascia 121. The amount of air that can be introduced has been greatly reduced. In the case where the amount of air is insufficient, the power unit 13 is further prevented from being cooled by sufficient outside cold air, which may affect the service life of the power unit 13.

Referring to Fig. 2, the locomotive 2 disclosed in the invention patent No. CN1376606A, "The front fairing support structure and windshield structure of a motorcycle" is disclosed. The locomotive 2 includes a body 21, a front wheel 22, a casing 23, a front wheel cover 24, a radiator 25, a fuel tank 26, an air cleaner 27, and an engine 28. An air inlet space 29 is formed in the windward portion between the casing 23 and the front wheel upper cover 24, and the casing 23 includes a plurality of air guiding openings 231 disposed behind the front wheel upper cover 24. The radiator 25 is inclined toward the front wheel 22, and the air cleaner 27 includes an air suction pipe 271 that allows outside air to enter the air cleaner 27 from the inside of the casing 23. Through the air inlet space 29 and the air guiding openings 231, the locomotive 2 can introduce the air at the maximum windward amount from the air inlet space 29 into the casing 23 through the air guiding openings 231 while traveling, so that the outside air is compared. The low-temperature cold air cools the radiator 25 in an air-cooled manner, and the hot air generated by the heat exchange is discharged from the lower side of the vehicle body 21, so that the heat sink 25 can be stably maintained at a low temperature to be stably used.

However, although the conventional locomotive 2 seems to solve the problem that the conventional locomotive 1 has insufficient air intake, in the conventional locomotive 2, the air introduced from the air vents 231 is mainly used to cool the radiator 25, plus Since the arrangement of the radiator 25 is inclined toward the front wheel 22, the oil tank 26 is also inclined toward the front wheel 22 to increase the volume of the oil tank 26 such that the top edge of the oil tank 26 is higher than the height of the front wheel cover 24. Therefore, after the outside air passing through the air inlet space 29 descends along the arc of the front wheel cover 24 to the air guiding ports 231 and enters the casing 23, the oil tank 26 is blocked and the heat sink 25 is directed downward. The direction flows and is discharged from the lower side of the vehicle body 21, and it is impossible to concentrate into the intake pipe 271 of the air cleaner 27 at all. In other words, although the conventional locomotive 2 is provided with an air guiding opening 231 for air entering at the windward side of the locomotive 2, the large amount of air introduced into the casing 23 cannot be directly used to cool the engine 28, resulting in the engine 28 Still can't be cooled quickly.

Accordingly, it is an object of the present invention to provide a locomotive having a heat-dissipating air guiding effect that can efficiently introduce a large amount of air for active use and can effectively cool the engine.

Referring to FIG. 4 and FIG. 6, according to the above structure, since the windward surface is located at the front panel portion 351, the front soil portion 34 and the front wheel 33 when the locomotive 3 is traveling, a large amount of air from the outside can be The air inlet space 301 enters the vehicle body space 350 through the air inlet 302, and smoothly flows through the oil tank 36 along the air passage 303, and blows around the engine 37 to enter the air suction pipe 391. The air cleaner 39 is filtered and further used by the engine 37. In addition, the suction pipe 391 extends into the inner side of one of the side cover portions 354 by more than 50 mm, and the suction port 392 is lower than the top edge of the oil tank 36, so that large particles of dust in the outside air can be It is blocked by one of the side cover portions 354 and the top edge of the oil tank 36, and does not directly enter the air suction pipe 391, thereby achieving an improvement in dustproofness. Furthermore, in addition to the air inlet space 301 and the air inlet 302, outside air can also enter the vehicle body space 350 through the cooling holes 355 of the shroud cover portion 353, and along the outer edge of the fuel tank 36.
