[0002] At present, most motorcycles are equipped with a radiator and a cooling fan on the front side. The radiator is connected to the engine and can dissipate heat from the engine. The cooling fan is connected to the radiator and can improve the heat dissipation efficiency of the radiator.

[0003] In the related art, motorcycles are generally equipped with radiator air scoops. Conventional radiator air scoops only use a single plastic part for heat insulation and air guiding. The radiator air scoop is usually arranged between the engine and the cooling fan. Since the radiator air scoop cannot be completely fitted with the engine, a gap exists between the radiator air scoop and the engine, so that the hot air around the cooling fan passes through the gap to the legs of the rider, thereby reducing the thermal insulation performance of the motorcycle. Utility Model Content

[0004] In order to solve the deficiencies of the prior art, the purpose of the present application is to provide a motorcycle with high thermal insulation performance.

[0022] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the specific implementation manner of the present application will be clearly and completely described below in conjunction with the drawings in the implementation manner of the present application.

[0023] like Figure 1 and Figure 2 A motorcycle 100 is shown, and the motorcycle 100 includes a frame 11, a running assembly 12, a body cover 13, a power system 14, and a cooling system 15. The frame 11 constitutes the basic framework of the motorcycle 100, and is used to support the body cover 13, the power system 14, and the cooling system 15. The running assembly 12 includes a front wheel 121 and a rear wheel 122, and the front wheel 121 and the rear wheel 122 are both used for the movement of the motorcycle 100. The body cover 13 is at least partially connected to the frame 11, and the body cover 13 is used to protect the internal parts of the motorcycle 100. The power system 14 includes an engine 141, which is supported by the frame 11 and is transmission-connected to the running assembly 12, and the engine 141 can drive the front wheel 121 and / or the rear wheel 122 to move.

[0024] like Figure 3 As shown, specifically, the cooling system 15 includes a cooling fan 151 and a radiator 152 located at the front side of the engine 141. The cooling fan 151 is connected to the radiator 152 and is located at the rear side of the radiator 152. The radiator 152 is connected to the frame 11. The radiator 152 is connected to the engine 141 to achieve heat dissipation of the engine 141. The cooling fan 151 has a rotational degree of freedom. The cooling fan 151 can improve the heat dissipation efficiency of the radiator 152. In order to clearly explain the technical solution of the application, it is also defined as follows Figure 1 In the present application, the length direction of the frame 11 refers to the front-rear direction, the width direction of the frame 11 refers to the left-right direction, and the height direction of the frame 11 refers to the up-down direction. Specifically, the travel assembly 12 is at least partially located below the frame 11.

[0025] like Figure 3As shown, as an implementation mode, the vehicle body cover 13 includes a first air guide 131 and a second air guide 132, along the length direction of the vehicle frame 11, the first air guide 131 and the second air guide 132 are at least partially located between the engine 141 and the radiator 152, the first air guide 131 is connected to the radiator 152, one side of the second air guide 132 is connected to the first air guide 131, the other side of the second air guide 132 is in contact with the engine 141, and the elastic modulus of the first air guide 131 is less than the elastic modulus of the second air guide 132. Specifically, along the length direction of the vehicle frame 11, the first air guide 131 is connected to the rear side of the radiator 152, and the front side of the second air guide 132 is connected to the rear side of the first air guide 131, so that the first air guide 131 and the second air guide 132 completely cover the gap between the engine 141 and the cooling fan 151. Through the above arrangement, it is possible to prevent the heat of the cooling fan 151 from being conducted backward and contacting the legs of the rider, thereby facilitating the improvement of the heat insulation performance of the motorcycle 100. It should be noted that the first air guide 131 is made of plastic material, and the second air guide 132 is made of rubber material. The plastic material has a relatively high strength to support the second air guide 132, and the rubber material has a relatively good deformation ability to enable the second air guide 132 to fit tightly on the engine 141, thereby facilitating the improvement of the rationality of the layout of the first air guide 131 and the second air guide 132.

[0026] like Figure 2 and Figure 3 As shown, in this embodiment, along the length direction of the frame 11, the second air guide 132 at least partially extends backward to form a fitting portion 1321, and a protrusion 1411 is formed on the engine 141, and the fitting portion 1321 fits on the engine 141 and is engaged with the protrusion 1411. Specifically, a through hole extending along the height direction of the frame 11 is provided on the fitting portion 1321, and the size of the through hole is substantially equal to the size of the protrusion 1411, so that the fitting portion 1321 can fit on the surface of the engine 141, and the fitting portion 1321 can be engaged with the protrusion 1411. Through the above arrangement, the connection stability between the fitting portion 1321 and the engine 141 can be improved, which is beneficial to improving the sealing performance of the second air guide 132 and the engine 141, and further beneficial to the heat insulation performance of the motorcycle 100.

[0027] As an implementation, the heat dissipation system 15 further includes a water tank connecting pipe 153 and a mounting connector 154, the water tank connecting pipe 153 is connected to the radiator 152, the water tank connecting pipe 153 is passed through the mounting connector 154 and is connected to the second air guide 132. Through the above arrangement, the mounting connector 154 can be connected to the second air guide 132, and the mounting connector 154 can limit the movement of the water tank connecting pipe 153, so that the water tank connecting pipe 153 is fixed on the second air guide 132, which is conducive to improving the bearing capacity of the second air guide 132, and at the same time, the structure of the second air guide 132 and the water tank connecting pipe 153 is more compact, which is also conducive to improving the compactness of the structure of the second air guide 132 and the water tank connecting pipe 153.

[0028] like Figure 4 As shown, in this embodiment, the first air guide 131 is provided with a first mounting portion 1311, the second air guide 132 is provided with a second mounting portion 1322, and the mounting connector 154 is connected to the first mounting portion 1311 and the second mounting portion 1322 at the same time. Specifically, the first mounting portion 1311 may be provided with a first through hole, the second mounting portion 1322 may also be provided with a second through hole connected to the first through hole, and the mounting connector 154 is provided with an expansion stud, which can be snapped into the first through hole and the second through hole. Through the above arrangement, the first air guide 131, the second air guide 132 and the mounting connector 154 can be installed at the same point to avoid setting too many connection points, which is conducive to improving the assembly efficiency of the first air guide 131, the second air guide 132 and the mounting connector 154, and further conducive to improving the assembly performance of the motorcycle 100.

[0029] like Figure 2 As shown, as an implementation method, the frame 11 includes a support frame 111, and the engine 141 includes a mounting portion 1412, and the mounting portion 1412 is connected to the support frame 111. Among them, the second air guide 132 includes an annular connection portion 1323, and the annular connection portion 1323 is located between the support frame 111 and the mounting portion 1412 and connected to the support frame 111. Specifically, along the width direction of the frame 11, since the width of the second air guide 132 along the width direction of the frame 11 is relatively large, the annular connection portion 1323 is arranged at the end of the second air guide 132, and the annular connection portion 1323 is connected to the support frame 111. Through the above arrangement, the support frame 111 has a higher strength, which is conducive to improving the connection strength between the second air guide 132 and the support frame 111, so as to prevent the second air guide 132 from being deformed and unable to fit on the surface of the engine 141, thereby helping to improve the sealing performance of the second air guide 132.

[0030] like Figure 4 and Figure 5As shown, in this embodiment, a limiting hole 1324 is further provided on the second air guide 132, and a limiting block 1325 is formed on the annular connection portion 1323, and the limiting block 1325 is clamped in the limiting hole 1324. Specifically, since the annular connection portion 1323 is sleeved on the support frame 111, and the annular connection portion 1323 has a gap, the present application provides a limiting hole 1324 on the second air guide 132, so that the limiting block 1325 of the annular connection portion 1323 is clamped in the limiting hole 1324, thereby closing the gap of the annular connection portion 1323. Through the above arrangement, the connection strength between the annular connection portion 1323 and the support frame 111 can be improved, thereby improving the structural stability of the second air guide 132. In addition, the disassembly speed of the limiting block 1325 and the limiting hole 1324 is fast, which is also conducive to improving the disassembly and assembly efficiency of the second air guide 132.

[0031] As an implementation mode, the first air guide 131 is provided with a first connection hole 1312, and the second air guide 132 is also provided with a second connection hole 1326. The first connection hole 1312 and the second connection hole 1326 are connected by an expansion screw 1313, and the second connection hole 1326 is arranged near the limiting hole 1324. Specifically, since the first air guide 131 and the second air guide 132 are relatively large in volume, the present application provides a plurality of first connection holes 1312 on the first air guide 131, and a plurality of second connection holes 1326 corresponding to the first connection holes 1312 on the second air guide 132, and the expansion screws 1313 are clamped in the first connection holes 1312 and the second connection holes 1326, so that the first air guide 131 and the second air guide 132 are fixedly connected. Through the above arrangement, the connection strength between the first air guide 131 and the second air guide 132 can be improved, and the disassembly and assembly speed of the expansion screw 1313 is relatively fast, which is also conducive to improving the assembly efficiency of the first air guide 131 and the second air guide 132. In addition, the second connection hole 1326 and the limiting hole 1324 have a compact structure, so that the structure of the support frame 111 and the first air guide 131 is more compact, which is also conducive to improving the structural compactness of the first air guide 131 and the support frame 111.

[0032] Exemplarily, when viewed along the length direction of the frame 11, the first air guide 131, the second air guide 132, the cooling fan 151 and the radiator 152 at least partially overlap. Through the above arrangement, the structures of the first air guide 131, the second air guide 132, the cooling fan 151 and the radiator 152 can be made more compact, so as to prevent the first air guide 131 and the second air guide 132 from occupying a large vehicle body space, thereby facilitating improving the compactness of the structure of the motorcycle 100.

[0033] As an implementation method, a heat dissipation duct 101 is formed between the first air guide 131, the second air guide 132, the radiator 152 and the engine 141, and the air outlet of the heat dissipation duct 101 is oriented toward the bottom of the radiator 152. Specifically, the heat dissipation fan 151 forms a hot air flow during rotation, and the hot air flow flows in the heat dissipation duct 101. The first air guide 131 and the second air guide 132 can prevent the hot air flow from being conducted to the legs of the rider along the length direction of the frame 11, and conduct the hot air flow to the ground, thereby facilitating the improvement of the driving comfort of the motorcycle 100.
