Description

[0002] With the rapid development of the motorcycle industry, small and medium-displacement scooters have become one of the daily travel and entertainment methods for modern consumers. While pursuing wind and freedom, people have more and more demands for riding experience. In terms of power, in addition to pursuing power comfort and smoothness, they are also very concerned about the ultimate acceleration feeling of power.

[0003] The ultimate acceleration feeling is closely related to the maximum power of the engine. The engine power needs to be increased. The increase in power also means that a stronger cooling capacity is needed. Many current radiator layouts have the problem of insufficient cooling air volume. Increasing the radiator and the fan will increase the development cost accordingly. In addition, after the engine power increases, higher requirements are also placed on oil heat dissipation. In scooters without oil coolers, the engine oil pan is mainly used for heat dissipation. In past developments, heat dissipation is mostly enhanced by adding cooling ribs. However, the scooter's cover has a good wrapping effect on the body, the airflow utilization rate is not high, the airflow speed near the oil pan is low, and some even have speed dead zones, so it is difficult to meet the heat dissipation requirements by simply adding cooling ribs.

[0004] Therefore, in view of the above technical problems, how to improve the problems of insufficient cooling air volume and unreasonable cooling air distribution in the current motorcycle cooling system is a technical problem that technical personnel in this field need to solve.

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0031] It should be noted that in this embodiment, the directions or positional relationships indicated by "upper", "lower", "front", "back", etc. are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present application. In addition, "first", "second", "third", and "fourth" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0032] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0033] like Figure 1 As shown, in this embodiment, an air volume distribution system is provided, which includes a radiator 1, an upper air deflector 3, a rear air deflector 4 and a bottom guard plate 5. The radiator 1 is a conventional radiator 1 in an existing motorcycle. The radiator 1 is arranged between the front fender 8 and the fuel tank 6 of the motorcycle. Front inner lining plates 2 are arranged on the left and right sides of the radiator 1. Compared with the traditional inner lining plate structure, the present application extends the two front inner lining plates 2 in an outwardly expanding manner toward the side where the front fender 8 is located. Please refer to Figure 2 , thereby increasing the air inlet in front of the radiator 1, making full use of the airflow on both sides of the front vehicle body, reducing the air inlet resistance of the radiator 1, and increasing the air inlet volume of the radiator 1; according to the air volume demand and the assembly problem with the fairing, the outward expansion angle can be selected between 10° and 25°, which is the deflection angle of the front inner lining plate 2 towards the positive and negative directions of Y based on the positive direction of X. For details, please refer to Figure 3 .

[0034] The upper air duct 3 is arranged on the upper side of the radiator 1, and a first air duct 14 for air intake toward the radiator 1 is formed between the upper air duct 3 and the front fender 8. At the same time, the upper section of the second air duct 15 is formed between the upper air duct 3 and the fuel tank 6. The first air duct 14 can increase the air intake of the radiator 1 core, enhance the heat exchange effect of the radiator 1, and improve the cooling capacity of the radiator 1.

[0035] The rear air deflector 4 is arranged at the air outlet side of the radiator 1, and includes a rear back plate 12 located between the radiator 1 and the oil tank 6, the upper end of the rear back plate 12 extends toward the upper air deflector 3, and the lower section of the second air duct 15 is formed between the rear back plate 12 and the oil tank 6; the bottom guard plate 5 is arranged at the lower end of the rear back plate 12, and the bottom guard plate 5 extends toward the direction of the oil pan 9, and the tail section of the second air duct 15 is formed between the bottom guard plate 5 and the oil tank 6, and the second air duct 15 discharges air toward the oil pan 9. Through the second air duct 15, more of the front airflow can be directed to the bottom of the oil pan 9, thereby enhancing the heat dissipation effect of the oil pan 9.

[0036] On the basis of the above-mentioned embodiment, the front inner lining plate 2 and the setting mode of the two air ducts are combined to form an air volume distribution system. The air volume distribution can be controlled by adjusting the height of the upper air guide cover 3, thereby increasing the air volume entering the radiator 1, reducing the coolant temperature, ensuring the engine reliability, and extending the service life of the engine. The air volume and wind speed can be greatly improved.

[0037] In summary of the above embodiments, the present application changes the shape and angle of the front inner lining plate 2 so that the two front inner lining plates 2 are arranged in an outwardly expanding manner, thereby forming a "trumpet-shaped" wind-gathering structure of the two front inner lining plates 2, thereby increasing the air inlet area and reducing the wind inlet resistance of the radiator 1; the airflow on both sides of the front wheel of the motorcycle can enter the radiator 1 to a greater extent through the wind-gathering effect of the inner lining plate, thereby increasing the air intake volume of the radiator 1 and improving the speed dead zone and surface speed uniformity on both sides of the radiator 1. The present application divides the air duct between the front fender 8 and the oil tank 6 into a first air duct 14 and a second air duct 15 through the upper air deflector 3, forming a "λ" type air duct. The first air duct 14 can discharge air to the radiator 1, increase the air intake of the radiator 1 core, enhance the heat exchange effect of the radiator 1, and improve the cooling capacity of the radiator 1; the upper section of the second air duct 15 is composed of the upper air deflector 3 and the oil tank 6, the lower section of the second air duct 15 is composed of the rear air deflector 4 and the oil tank 6, the tail end of the second air duct 15 is composed of the bottom guard plate 5 and the oil tank 6, and the second air duct 15 can discharge air toward the oil pan 9 to cool the bottom of the oil pan 9. Therefore, the present application can ensure that the front radiator 1 has enough air volume to cool the heat dissipation fins, and can allocate part of the air volume to flow toward the rear of the vehicle to cool the bottom of the oil pan 9, improve the oil heat dissipation performance, and improve reliability.

[0038] In some embodiments, in order to enable the radiator 1 to better receive the airflow in the first air duct 14, the angle between the radiator 1 and the horizontal ground can be maintained between 60° and 80°, and the upper end of the radiator 1 is tilted backward compared to the lower end of the radiator 1. Figure 1 or Figure 5 .

[0039] Please refer to Figure 5 , which is a simplified schematic diagram of the air volume distribution system. On the basis of the "trumpet-shaped" wind gathering mechanism of the front inner lining plate 2, in order to ensure that the airflow circulates more smoothly in the first air duct 14, the overall curvature of the upper air duct 3 can be kept consistent with the curvature of the corresponding front fender 8; at the same time, the upper end of the upper air duct 3 should be lower than the highest point of the front fender 8, and the lower end of the upper air duct 3 is higher than the lowest point of the front fender 8, to ensure that the upper air duct 3 can fully cooperate with the front fender 8 to form the first air duct 14, thereby providing sufficient air volume for the radiator 1.

[0040] In addition, there is an inclined surface 7 on the upper end of the oil tank 6 near the second air duct 15, please refer to Figure 5 Considering that part of the airflow needs to be distributed to the second air duct 15, the upper end of the upper air deflector 3 is preferably not higher than the tangent position of the inclined surface 7, so that the airflow can be divided into two paths at the upper end of the upper air deflector 3 and enter the first air duct 14 and the second air duct 15 respectively; the upper end of the upper air deflector 3 can be fixed to the frame by means of a support ear and a bolt connection.

[0041] The lower end of the upper air deflector 3 also has a certain inclination angle, and the tangent of the lower end of the upper air deflector 3 points to the radiator 1, and the direction of the tangent is consistent with the flow direction of the airflow in the first air duct 14. Combined with the overall curvature of the upper air deflector 3 being consistent with the curvature of the front fender 8, the airflow can flow to the radiator 1 more smoothly, and it is not easy to cause turbulence and the like.

[0042] Since the radiator 1 is tilted relative to the ground and the upper air guide cover 3 is set with a certain curvature, there is an inflection point 16 at the connection between the upper air guide cover 3 and the radiator 1. Figure 5 The inflection point 16 should be set as close to the radiator 1 as possible to widen the air duct width and increase the air intake. The lower end of the traditional upper air guide cover not only changes the airflow direction, but also the inflection point is too far away from the radiator, resulting in a large area of ​​speed dead zone at the upper end of the radiator, which is not conducive to the cooling of the radiator.

[0043] The tangent line at the lower end of the front fender 8 can intersect with the lowest point of the lower end of the radiator 1. If the tangent line at the lower end of the front fender 8 is lower than the lowest point of the lower end of the radiator 1, the airflow will be lost from the space between the tangent line and the lowest point of the radiator 1. The tangent line at the lower end of the front fender 8 is higher than the lowest point of the radiator 1, which makes it impossible for the airflow to cool the lower end of the radiator 1, resulting in a cooling dead zone.

[0044] On the premise of ensuring that the radiator 1 has sufficient air volume, more airflow can be allocated to cool the oil pan 9 by adjusting the upper end height of the upper air deflector 3, the curvature and lower end position of the rear air deflector 4, and the rear end angle of the bottom guard plate 5; specifically, the upper end of the upper air deflector 3 does not exceed the tangent position of the inclined surface 7 to ensure that the front flow can smoothly enter the second air duct 15, the overall curvature of the back plate 12 is consistent with the curvature of the lower part of the oil tank 6, to ensure the smoothness of the airflow in the second air duct 15, and the position of the lower end of the back plate 12 is consistent with the position of the oil pan 9 or is lower than 2 cm, to ensure that the lower end of the back plate 12 can be lower than the lowest point of the oil tank 6, and the bottom guard plate 5 can be set horizontally, so that the airflow can smoothly reach the oil pan 9 to cool the oil pan 9.

[0045] Of course, the configuration methods of the upper air deflector 3, the rear air deflector 4 and the bottom guard plate 5 include but are not limited to the methods given above, as long as it is ensured that the airflow can reach the radiator 1 through the first channel and the oil pan 9 through the second channel, all of which fall within the protection scope of the present application.

[0046] Also see Figure 4 The rear air guide cover 4 also includes side panels 13 located on both sides of the rear back plate 12. The two side panels 13 and the rear back plate 12 enclose a heat dissipation duct. The fan 11 of the radiator 1 is arranged on the air inlet side of the heat dissipation duct, and the air outlet side of the heat dissipation duct discharges air toward the ground. It can be seen that the rear air guide cover 4 of the present application can use the rear back plate 12 to guide the hot air of the fan 11 to the ground to avoid blowing toward electrical components and affecting reliability, and at the same time use the two side panels 13 to prevent the blown hot air from escaping everywhere.

[0047] Please refer to Figure 6 Side guide plates 10 extending toward the fuel tank 6 are provided on both sides of the upper air guide cover 3 and the rear air guide cover 4. The side guide plates 10 are fixedly connected to the motorcycle frame to reduce the airflow escape in the second air duct 15. The side guide plates 10 and the frame can be connected with the support ears by bolts.

[0048] The present application also provides a motorcycle, which includes the above-mentioned air volume distribution system and of course other necessary components that make up the motorcycle, which will not be described here in detail and can be referred to the prior art.

[0049] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0050] Specific examples are used herein to illustrate the principles and implementation methods of the present application, and the description of the above embodiments is only used to help understand the method and core ideas of the present application. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications also fall within the scope of protection of the claims of the present application.
