At the same time, the air outlet is facing rightward of the air guide cover, so that the cooling hot air is blown directly to the driver's legs, causing a burning sensation in the driver's legs and causing discomfort. Summary of the Invention

[0003] The purpose of the present invention is to overcome the problems of the prior art and provide a motorcycle engine efficient cooling structure that can prevent cooling hot air from blowing towards the driver's legs to prevent local burning sensation in the legs and efficiently cool the legs, and also provide a motorcycle with the motorcycle engine efficient cooling structure.

[0004] In order to achieve the above object, the present invention adopts the following scheme:

[0005] A high-efficiency cooling structure for a motorcycle engine comprises a crankcase, wherein the front end of the crankcase is connected to a cylinder, and an air inlet cover is provided on one side of the crankcase; the front end of the air inlet cover is connected to an air guide cover which covers the outside of the cylinder and is located at the front end of the crankcase; the lower side of the air guide cover is provided with an air outlet facing obliquely rearward and downward of the air guide cover; the air guide cover is connected to a deflector arranged along the air outlet direction of the air outlet at an air outlet position corresponding to the air outlet to guide cooling hot air to be discharged obliquely rearward and downward from the air outlet.

[0006] Furthermore, an air outlet plate is provided in the air outlet for guiding the cooling hot air to be discharged obliquely rearward and downward from the air outlet.

[0007] Furthermore, the guide plate includes a first front guide plate and a second front guide plate; one end of the first front guide plate is connected to the front end surface of the air outlet, and the other end extends along the oblique rear and lower part of the air guide cover; one end of the second front guide plate is connected to the air outlet plate, and the other end extends along the oblique rear and lower part of the air guide cover.

[0008] Furthermore, the second front guide plate and the air outlet plate are integrally formed.

[0009] Furthermore, the guide plate further includes a rear guide plate; the rear guide plate is arranged on the air guide cover at a middle and rear end position corresponding to the air outlet and away from the air outlet.

[0010] Furthermore, the rear guide plate corresponds to the connection between the crankcase and the air intake cover.

[0011] Furthermore, the first front guide plate, the second front guide plate and the rear guide plate are parallel to each other.

[0012] Furthermore, the front end of the rear guide plate is correspondingly connected to the rear end of the second front guide plate; and the rear end of the rear guide plate is correspondingly connected to the rear end surface of the air outlet.

[0013] Furthermore, the lower end of the crankcase has an oil storage shell located below the air outlet; the lower end of the crankcase is also provided with a mounting bracket away from the air outlet direction of the air outlet; the mounting bracket has a box shock-absorbing pad for shockproofing.

[0014] The present invention also provides a motorcycle, comprising a vehicle body and the motorcycle engine efficient cooling structure as described above; the motorcycle engine efficient cooling structure is arranged on the vehicle body.

[0015] Compared with the existing technology, the present invention has the following advantages:

[0016] 1. The efficient cooling structure of the motorcycle engine takes in air through an air inlet cover, and is provided with an air outlet on the air guide cover facing obliquely rearward and downward along the air guide cover, and a deflector is provided at the air outlet position corresponding to the air outlet. By designing the direction of the air outlet and the setting direction of the deflector, the cooling hot air is concentrated and blown obliquely downward toward the rear of the entire vehicle, avoiding the cooling hot air from blowing toward the driver's legs to prevent local burning sensation in the legs.

[0017] 2. The present invention can better prevent muddy water splashed from the front wheel platform from accumulating at the air outlet and causing blockage of the air outlet by setting the direction of the air outlet, the guide plate, and the setting direction of the guide plate.

[0018] 3. Since the temperature of the cooling hot air is much lower than the temperature of the engine oil, by setting the direction of the air outlet, the guide plate, and the setting direction of the guide plate, the cooling hot air discharged from the air outlet can be blown toward the crankcase under the action of the guide plate, which can take away the heat transferred from the engine oil to the surface of the oil casing, thereby effectively lowering the oil temperature, reducing the heat load of the engine, and improving the engine performance.

Specifically, an air inlet cover 2 is provided on the right side of the crankcase 1; the front end of the air inlet cover 2 is connected to an air guide cover 3 which covers the outside of the cylinder and is located at the front end of the crankcase 1; the lower end of the crankcase 1 has an oil storage shell 11 located below the air outlet 4; the lower side of the air guide cover 3 is provided with an air outlet 4 facing obliquely rearward and downward of the air guide cover 3; the air guide cover 3 is connected to a deflector 5 arranged along the air outlet direction of the air outlet 4 at the air outlet position corresponding to the air outlet 4 to guide the cooling hot air to be discharged obliquely rearward and downward from the air outlet 4.

[0027] The motorcycle engine high-efficiency cooling structure is characterized in that: the air inlet of the motorcycle engine high-efficiency cooling structure is arranged at the air inlet cover 2, the air outlet 4 is arranged at the lower part of the air guide cover 3, and the flow guide plate 5 extending along the rear lower part of the air guide cover 3 is arranged at the position corresponding to the air outlet 4; the direction of the air outlet 4, the flow guide plate 5 and the setting direction of the flow guide plate 5 are designed so that the cooling hot air is concentrated and blows obliquely downward to the rear of the whole vehicle, the cooling hot air is prevented from blowing to the legs of the driver to prevent the local legs from being hot, the mud splashed by the front tire is prevented from being accumulated at the air outlet 4 to cause the air outlet 4 to be blocked, the cooling hot air discharged from the air outlet 4 is blown to the crankcase 1 under the action of the flow guide plate 5, the heat transferred to the surface of the oil shell by the oil is taken away, the oil temperature is effectively reduced, the thermal load of the engine is reduced, and the performance of the engine is improved.

[0028] In order to better make the cooling hot air concentrate and blow obliquely downward to the rear of the whole vehicle, and further achieve the effect, the air outlet 4 is provided with an air outlet plate 6 for guiding the cooling hot air to blow obliquely downward from the air outlet 4. By arranging the air outlet plate 6 in the air outlet 4, on the one hand, the air outlet plate 6 plays a good blocking role to prevent mud, stones and the like from splashing into the air outlet 4; on the other hand, the air outlet plate 6 guides the cooling hot air, further makes the cooling hot air concentrate and blow obliquely downward to the rear of the whole vehicle, avoids the cooling hot air from blowing to the legs of the driver to prevent the local legs from being hot, better prevents the mud splashed by the front tire from being accumulated at the air outlet 4 to cause the air outlet 4 to be blocked, and makes the cooling hot air discharged from the air outlet 4 blow to the crankcase 1 under the action of the flow guide plate 5, takes away the heat transferred to the surface of the oil shell by the oil, effectively reduces the oil temperature, reduces the thermal load of the engine, and improves the performance of the engine.

[0029] The deflector 5 includes a first front deflector 51, a second front deflector 52, and a rear deflector 53. One end of the first front deflector 51 is connected to the front end of the air outlet 4, and the other end extends along the obliquely rearward and downward direction of the air deflector 3. One end of the second front deflector 52 is connected to the air outlet plate 6, and the other end extends along the obliquely rearward and downward direction of the air deflector 3. The rear deflector 53 is provided on the air deflector 3 at a position corresponding to the air outlet 4 and away from the middle and rear end of the air outlet 4. By setting the position and direction of the first front guide plate 51 and the second front guide plate 52, it is possible to better prevent muddy water splashed by the front wheel platform from accumulating at the air outlet 4, causing the air outlet 4 to be blocked; and under the action of the first front guide plate 51 and the second front guide plate 52, the cooling hot air discharged from the air outlet 4 can be further concentrated and blown obliquely downward to the rear of the vehicle, thereby preventing the cooling hot air from blowing towards the driver's legs to prevent a local burning sensation on the legs; it can also better avoid The mud and water splashed by the front tires are prevented from accumulating at the air outlet 4, causing the air outlet 4 to be blocked; at the same time, the position and direction of the rear guide plate 53 are set so that the rear guide plate 53 is away from the middle and rear end position of the air outlet 4, that is, the downstream position of the air outlet 4, and combined with the first front guide plate 51 and the second front guide plate 52, the cooling hot air can be better blown to the crankcase 1, and the heat transferred from the oil to the surface of the oil casing by the air outlet can be reasonably used to take away the heat, thereby effectively reducing the oil temperature, reducing the heat load of the engine, and improving the performance of the engine.

[0030] Preferably, the first front guide plate 51, the second front guide plate 52 and the rear guide plate 53 are parallel to each other and set at reasonable angles, which can uniformly guide the cooling hot air well, thereby improving the efficient cooling performance of the motorcycle engine efficient cooling structure.

[0031] Preferably, the front end of the rear guide plate 53 is correspondingly connected with the rear end of the second front guide plate 52; the rear end of the rear guide plate 53 is correspondingly connected with the rear end surface of the air outlet 4, that is, it can be understood that, with the mouth surface of the air outlet 4 as the projection surface, the second front guide plate 52 and the rear guide plate 53 are projected on the mouth surface of the air outlet 4, and the projected front end of the rear guide plate 53 is connected with the projected rear end of the second front guide plate 52. At the same time, the projected rear end of the rear guide plate 53 is correspondingly connected with the rear end surface of the air outlet 4, so that the rear guide plate 53 can effectively blow the cooling hot air (i.e., the outlet air) toward the crankcase 1, and reasonably use the outlet air to take away the heat transferred from the engine oil to the surface of the oil casing, thereby effectively reducing the oil temperature, reducing the heat load of the engine, and improving the performance of the engine.

[0032] In order to improve the efficiency of assembly and disassembly and facilitate the assembly of the device, the second front guide plate 52 is integrally formed with the air outlet plate 6. By setting the second front guide plate 52 and the air outlet plate 6 as one piece, the assembly and disassembly of the device are convenient, which is conducive to cost saving.

[0033] In order to further better utilize the outlet air to remove the heat transferred from the engine oil to the surface of the oil casing, thereby effectively reducing the engine oil temperature, reducing the thermal load of the engine, and improving the engine performance, the rear guide plate 53 corresponds to the connection between the crankcase 1 and the air inlet cover 2. In this specific embodiment, the first front guide plate 51, the second front guide plate 52, and the rear guide plate 53 are all on the lower end plane of the same air guide cover 3. By setting the rear guide plate 53 to correspond to the connection between the crankcase 1 and the air inlet cover 2, the purpose is to set the rear guide plate 53 at the downstream position of the air outlet 4, blocking the outlet air from blowing towards the air inlet cover 2, effectively concentrating the cooling hot air (i.e., the outlet air) to blow towards the crankcase 1, and rationally utilizing the outlet air to remove the heat transferred from the engine oil to the surface of the oil casing, thereby effectively reducing the engine oil temperature, reducing the thermal load of the engine, and improving the engine performance.

[0034] In this embodiment, the lower end of the crankcase 1 is further provided with a mounting bracket 7, positioned away from the outlet 4 in the direction of airflow. This mounting bracket 7 houses a vibration-damping pad for shock absorption. By positioning the mounting bracket 7 away from the outlet 4 and providing a deflector 5 to block the flow, the exhaust air is prevented from blowing towards the mounting bracket 7 and the vibration-damping pad, effectively extending the life of the vibration-damping pad.

[0035] The present invention also provides a motorcycle comprising a motorcycle body and the above-described efficient motorcycle engine cooling structure; the efficient motorcycle engine cooling structure is disposed on the motorcycle body. The installation of the efficient motorcycle engine cooling structure on the motorcycle body effectively reduces engine oil temperature, reduces the heat load on the engine, and improves the overall performance of the motorcycle.

[0036] In summary, the embodiment of the present invention provides an efficient cooling structure for a motorcycle engine, wherein the efficient cooling structure for a motorcycle engine is realized by taking in air through an air inlet hood 2, arranging an air outlet 4 at the lower part of the air guide hood 3, and extending along the oblique rear lower part of the air guide hood 3 at the position corresponding to the air outlet 4. By designing the direction of the air outlet 4, the air guide 5, and the arrangement direction of the air guide 5, the cooling hot air is concentrated and blown obliquely downward toward the rear of the entire vehicle, avoiding the cooling hot air from blowing toward the driver's legs to prevent local burning sensation on the legs; it can also better avoid the accumulation of mud and water splashed by the front tire at the air outlet 4, causing the air outlet 4 to be blocked; and the cooling hot air discharged from the air outlet 4 can be blown toward the crankcase 1 under the action of the air guide 5, which can take away the heat transferred from the engine oil to the surface of the oil casing, thereby effectively reducing the engine oil temperature, reducing the heat load of the engine, and improving the performance of the engine.
