[0027] In order to enable those skilled in the art to better understand the solution of the present application, the technical solutions in the specific implementation manners of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the implementation manners of the present application.

[0028] The present application provides a motorcycle 100 as Figure 1 shown. The motorcycle 100 includes a frame 11, a body covering 12, a suspension assembly 13, a running assembly 14, and a power system 15. The body covering 12 is at least partially disposed on the frame 11. The suspension assembly 13 is connected to the frame 11, and the running assembly 14 is connected to the frame 11 through the suspension assembly 13. The power system 15 is at least partially disposed on the frame 11, and the power system 15 is in transmission connection with the running assembly 14. The running assembly 14 includes a front wheel 141 disposed at the front end of the motorcycle 100 and a rear wheel 142 disposed at the rear end of the motorcycle 100. Specifically, the power system 15 is at least partially in transmission connection with the rear wheel 142. In order to clearly illustrate the technical solution of the application, the front, rear, left, right, up, and down as Figure 1 shown are also defined. In the present application, the length direction of the motorcycle 100 refers to the above-mentioned front-rear direction, the width direction of the motorcycle 100 refers to the above-mentioned left-right direction, and the height direction of the motorcycle 100 refers to the above-mentioned up-down direction.

[0029] As Figures 1 to 3As shown, as an implementation, the motorcycle 100 includes an electrical system 23. The electrical system 23 includes an electric air pump 231 for inflating the front wheel 141 and / or the rear wheel 142. The electric air pump 231 is detachably connected to the body cover 12. The body cover 121 forms an accommodation space 126 around it, and the electric air pump 231 is at least partially located in the accommodation space 126. Among them, the body cover 12 includes a rear cover 121 arranged behind the frame 11. The rear cover 121 includes a rear mudguard 1211 and an upper support plate 1212. The rear mudguard 1211 is at least partially located under the frame 11, and the upper support plate 1212 is at least partially located above the frame 11. The rear mudguard 1211 and the upper support plate 1212 are connected. The electric air pump 231 is at least partially located between the rear mudguard 1211 and the upper support plate 1212, and the electric air pump 231 is connected to the rear mudguard 1211. Specifically, both the rear mudguard 1211 and the upper support plate 1212 are connected to the frame 11 to stably connect the rear mudguard 1211 and the upper support plate 1212, and the electric air pump 231 is connected to the rear mudguard 1211. Through the above settings, integrating the electric air pump 231 into the interior of the motorcycle 100 can avoid the external placement of the electric air pump 231, which is beneficial to improving the space utilization rate of the motorcycle 100. Moreover, the electric air pump 231 is arranged close to the rear wheel 142. When the rear wheel 142 is short of air, the electric air pump 231 can directly inflate the rear wheel 142, which is beneficial to reducing the operation process of the driver and further improving the functional diversity of the motorcycle 100.

[0030] As an implementation, the motorcycle 100 includes a saddle assembly 24. The saddle assembly 24 is located above the frame 11. The rear side of the saddle assembly 24 abuts against the upper support plate 1212, and the electric air pump 231 is at least partially located under the saddle assembly 24. Specifically, the front end portion of the electric air pump 231 is located under the rear end portion of the saddle assembly 24, and the rear end portion of the electric air pump 231 is located under the upper support plate 1212. And the accommodation space 126 communicates with the lower space of the saddle assembly 24, so that the electric air pump 231 can be detached from the rear mudguard 1211 through the lower space of the saddle assembly 24. When the running assembly 14 needs to be inflated, the saddle assembly 24 can be opened first, and then the electric air pump 231 can be removed to realize the inflation of the running assembly 14. Through the above settings, the structure of the electric air pump 231 and the saddle assembly 24 is compact, which is beneficial to improving the structural compactness of the motorcycle 100.

[0031] As an implementation, a plurality of clamping portions 1211c are provided on the rear fender 1211, and the electric air pump 231 is clamped to the clamping portion 1211c. Specifically, the clamping portion 1211c is disposed around the electric air pump 231, and the clamping portion 1211c abuts against the front side and the rear side of the electric air pump 231 to limit the forward or backward movement of the electric air pump 231. At the same time, the clamping portion 1211c abuts against the left side and the right side of the electric air pump 231 to limit the left or right movement of the electric air pump 231. Through the above settings, the connection between the electric air pump 231 and the rear fender 1211 is stable, which is beneficial to improving the structural stability of the motorcycle 100.

[0032] As an implementation, a connecting portion 1211d and a connecting member 1211e are provided on the rear fender 1211. The connecting member 1211e is clamped in the connecting portion 1211d, and the connecting member 1211e is at least partially disposed around the electric air pump 231 to connect the electric air pump 231 and the rear fender 1211. Specifically, the rear fender 1211 at least partially extends upward to form the connecting portion 1211d. The connecting portion 1211d is located on both sides of the electric air pump 231. The connecting portion 1211d can clamp the electric air pump 231. The connecting member 1211e is made of rubber material, and both ends of the connecting member 1211e can be clamped in the connecting portion 1211d. The cooperation between the connecting member 1211e and the connecting portion 1211d can limit the upward movement of the electric air pump 231 due to the bumping of the motorcycle 100. Through the above settings, the connection between the electric air pump 231 and the rear fender 1211 can be improved, which is beneficial to improving the structural stability of the motorcycle 100.

[0033] As an implementation, the electric air pump 231 includes an air pump body 2311 and an air delivery pipe 2312. The air pump body 2311 and the air delivery pipe 2312 are detachably arranged, and both the air pump body 2311 and the air delivery pipe 2312 are located in the accommodation space 126. Specifically, the air pump body 2311 is used to generate air flow, and the air delivery pipe 2312 is used to deliver the air flow generated by the air pump body 2311. At the same time, the air delivery pipe 2312 can be connected to the traveling assembly 14 to inject the air flow into the traveling assembly 14. Through the above settings, since the length of the air delivery pipe 2312 is relatively long, the air delivery pipe 2312 and the air pump body 2311 can be detachably arranged in the accommodation space 126, which is beneficial to improving the structural compactness of the air delivery pipe 2312, the air pump body 2311 and the rear fender 1211. When the traveling assembly 14 needs to be inflated, the air delivery pipe 2312 can be directly connected to the air pump body 2311 to realize the inflation of the traveling assembly 14, which is also beneficial to improving the convenience of the motorcycle 100.

[0034] As an implementation, a charging port 2311a is provided on the air pump body 2311. The motorcycle 100 includes a storage battery 26, and the wiring harness of the storage battery 26 is connected to the charging port 2311a so that the storage battery 26 is electrically connected to the air pump body 2311. Specifically, a small battery is provided inside the air pump body 2311, and the storage battery 26 can charge the small battery so that the small storage battery 26 can always be fully charged, which is beneficial to improving the working stability of the electric air pump 231. It should be noted that the electric air pump 231 can also inflate the traveling assembly 14 in the charging state, and an external charging port 2311a connected to an external power source is also provided on the electric air pump 231. When the storage battery 26 of the motorcycle 100 cannot charge the electric air pump 231, the electric air pump 231 can be charged through the external power source, which is beneficial to improving the charging efficiency of the electric air pump 231.

[0035] As an implementation, the electrical system 23 includes a rear tail light 232. At least a part of the rear tail light 232 is located in the accommodation space 126, and the electric air pump 231 is located on the front side of the rear tail light 232. Specifically, the rear tail light 232 is snap-fitted to the rear mudguard 1211 and the upper support plate 1212, and at least a part of the rear side of the electric air pump 231 abuts against the front side of the rear tail light 232 so that the rear tail light 232 provides a forward supporting force for the electric air pump 231. Through the above arrangement, the electric air pump 231 and the rear tail light 232 are structurally compact, and both the electric air pump 231 and the rear tail light 232 are at least partially located in the accommodation space 126, which is beneficial to improving the space utilization rate of the accommodation space 126. In this embodiment, the rear tail light 232 includes a connection wiring harness 2321. At least a part of the connection wiring harness 2321 is located in the accommodation space 126, and the connection wiring harness 2321 is arranged close to the electric air pump 231. Specifically, the connection wiring harness 2321 is used to connect the rear tail light 232 and the storage battery 26. The connection wiring harness 2321 passes through the accommodation space 126 and is electrically connected to the rear tail light 232 and the storage battery 26, which is also beneficial to improving the space utilization rate of the accommodation space 126. At the same time, the connection wiring harness 2321 is arranged on both sides of the electric air pump 231, which is also beneficial to improving the structural stability of the electric air pump 231 and the connection wiring harness 2321. In addition, the electric air pump 231 and the storage battery 26 are also electrically connected through the connection wiring harness 2321 so that the connection wiring harness 2321 can charge the electric air pump 231 and the rear tail light 232 at the same time, which is also beneficial to improving the charging efficiency of the electric air pump 231 and the rear tail light 232.

[0036] As Figure 4 and Figure 5As shown, as an implementation, the saddle assembly 24 is connected to the vehicle frame 11, and at least part of the saddle assembly 24 is located on the upper side of the vehicle frame 11. The vehicle frame 11 further includes a main vehicle frame 111 and a sub-vehicle frame 114. At least part of the main vehicle frame 111 is located in front of the sub-vehicle frame 114. At least part of the front side of the saddle assembly 24 is clamped to the main vehicle frame 111, and at least part of the saddle assembly 24 is clamped to the sub-vehicle frame 114. Specifically, the main vehicle frame 111 is fixedly connected to the sub-vehicle frame 114, and the saddle assembly 24 is for the driver to sit on. In this embodiment, a first insertion portion 241 is provided on the front side of the saddle assembly 24, and a first insertion member 1111 that is clamped to the first insertion portion 241 is provided on the main vehicle frame 111. The first insertion portion 241 can be clamped inside the first insertion member 1111. A second insertion portion 242 is further provided on the rear side of the saddle assembly 24, and a second insertion member 1143 that is clamped to the second insertion portion 242 is provided on the sub-vehicle frame 114. The second insertion portion 242 can be clamped inside the second insertion member 1143. Through the above settings, the saddle assembly 24 can be stably connected to the main vehicle frame 111 and the sub-vehicle frame 114, which is beneficial to improving the connection stability of the saddle assembly 24.

[0037] As an implementation, the first insertion member 1111 is provided as a cylindrical structure. The axis of the first insertion member 1111 extends in the width direction of the motorcycle 100. First conical portions 1111a are formed by extending radially outward at both ends of the first insertion member 1111 along the radial direction of the first insertion member 1111. At least part of the first insertion portion 241 is clamped between the first conical portions 1111a. Specifically, the first insertion member 1111 is provided as an I-shaped bushing. Since the I-shaped bushing has high stability, and the first insertion portion 241 moves forward from the rear of the motorcycle 100 and is clamped inside the first insertion member 1111, so that the first insertion portion 241 receives the supporting force of the first insertion member 1111, which is beneficial to the stability of the first insertion portion 241 and the first insertion member 1111 in the front-rear direction. At the same time, the first conical portions 1111a are provided on the first insertion member 1111 to facilitate the connection between the first insertion portion 241 and the second insertion member 1143, and further beneficial to improving the assembly efficiency of the saddle assembly 24 and the main vehicle frame 111.

[0038] As an implementation, the axis of the second plug-in member 1143 extends in the width direction of the motorcycle 100. Second conical portions 1143a are formed by extending both ends of the second plug-in member 1143 radially outward along the second plug-in member 1143. At least a part of the second plug-in portion 242 is clamped between the second conical portions 1143a. Specifically, the second plug-in member 1143 is arranged as an I-shaped bushing. Since the I-shaped bushing has high stability and the second plug-in portion 242 moves downward from the upper part of the motorcycle 100 and is clamped in the second plug-in member 1143, the second plug-in portion 242 is supported by the second plug-in member 1143, which is beneficial to the stability of the second plug-in portion 242 and the second plug-in member 1143 in the up-and-down direction. At the same time, the second conical portions 1143a are provided on the second plug-in member 1143 to facilitate the connection between the second plug-in portion 242 and the second plug-in member 1143, thereby being beneficial to improving the assembly efficiency of the saddle assembly 24 and the main frame 111.

[0039] As an implementation, an annular buffer member 1143b is arranged inside the second plug-in member 1143. The annular buffer member 1143b is sleeved on the second plug-in member 1143. At least a part of the second plug-in portion 242 abuts against the annular buffer member 1143b. Specifically, the annular buffer member 1143b can be made of rubber material to reduce the impact force between the second plug-in member 1143 and the second plug-in portion 242, thereby avoiding rigid connection between the saddle assembly 24 and the frame 11, and being beneficial to improving the service life of the saddle assembly 24 and the frame 11.

[0040] As an implementation, the first plug-in portion 241 is provided with a first opening 2411 that is clamped with the first plug-in member 1111, and the first opening 2411 is arranged facing the front side of the motorcycle 100. The second plug-in portion 242 is provided with a second opening 2421 that is clamped with the first plug-in member 1111, and the second opening 2421 is arranged facing the lower side of the motorcycle 100. Specifically, the first opening 2411 of the first plug-in portion 241 facing forward can abut against the upper side and the lower side of the first plug-in member 1111 to prevent the first plug-in portion 241 from moving up and down due to jolting during the running of the motorcycle 100. Similarly, the second opening 2421 of the second plug-in portion 242 facing downward can abut against the front side and the rear side of the second plug-in member 1143 to prevent the second plug-in portion 242 from moving back and forth due to acceleration or deceleration during the running of the motorcycle 100. Through the above settings, the connection stability between the saddle assembly 24 and the frame 11 can be improved, and thus it is beneficial to improving the stability of the motorcycle 100 during running.

[0041] As an implementation manner, a plurality of support members 243 are further provided on the lower side of the saddle assembly 24. The sub-frame 114 includes an upper main pipe 1141 that extends substantially in the front-rear direction, and the support member 243 abuts against the upper main pipe 1141. Specifically, the support member 243 is made of a plastic material with relatively high strength. The support member 243 can be disposed between the first plug-in member 1111 and the second plug-in member 1143 to provide support for the middle part of the saddle assembly 24, so as to avoid deformation caused by excessive pressure at a certain place of the saddle assembly 24, thereby being beneficial to improving the structural stability of the saddle assembly 24. Moreover, the plastic has a certain deformation ability and can play a buffering role, which is also beneficial to improving the shock absorption function of the saddle assembly 24.

[0042] As an implementation manner, the sub-frame 114 further includes a support plate 1144 that extends in the width direction. Along the length direction of the motorcycle 100, the support plate 1144 is located between the first plug-in member 1111 and the second plug-in member 1143, and at least a part of the support plate 1144 abuts against the lower side of the saddle assembly 24. Specifically, the support plate 1144 is connected to the upper main pipe 1141 to improve the strength of the upper main pipe 1141. At the same time, the support plate 1144 can also provide an upward supporting force for the saddle assembly 24, which is thus beneficial to improving the stability of the saddle assembly 24.

[0043] As an implementation, a clamping member 244 is further provided on the lower side of the saddle assembly 24 and is located between the first insertion portion 241 and the second insertion portion 242. A locking member 1144a connected to the clamping member 244 is further provided on the sub-frame 114. The clamping member 244 can be clamped within the locking member 1144a so that the bracket plate 1144 is fixedly connected to the saddle assembly 24. Specifically, the locking member 1144a is fixedly connected to the bracket plate 1144, and the locking member 1144a is located at the middle position of the bracket plate 1144. When the locking member 1144a is clamped with the clamping member 244, the movement of the saddle assembly 24 can be restricted, which is beneficial to improving the stability of the saddle assembly 24. At the same time, the locking member 1144a and the clamping member 244 are basically located at the middle position of the saddle assembly 24, so that the structures of the first insertion portion 241, the second insertion portion 242, the locking member 1144a and the clamping member 244 are more compact, which is beneficial to improving the structural compactness of the motorcycle 100. In addition, the distance between the first insertion portion 241 and the locking member 1144a in the front-back direction of the motorcycle 100 is set as a first distance, and the distance between the second insertion portion 242 and the locking member 1144a in the front-back direction of the motorcycle 100 is set as a second distance. The ratio of the first distance to the second distance is greater than or equal to 0.2 and less than or equal to 4. Further, the ratio of the first distance to the second distance is greater than or equal to 1 and less than or equal to 2. More specifically, the ratio of the first distance to the second distance is 1.5. Through the above settings, it can be avoided that the locking member 1144a is too far back due to the too large ratio of the first distance to the second distance, so as to prevent the locking member from occupying a large layout space of the saddle assembly 24, which is beneficial to improving the space utilization rate of the saddle assembly 24; and it can also be avoided that the locking member 1144a is too far forward due to the too small ratio of the first distance to the second distance, so as to prevent the connection strength between the saddle assembly 24 and the main frame 111 from being too low, which is beneficial to improving the connection stability between the saddle assembly 24 and the main frame 111. It should be noted that the locking member 1144a can be set as an electric lock or other components that can be opened from the outside to facilitate the disassembly and installation of the saddle assembly 24.

[0044] As an implementation, a connecting plate 1112 is provided on the main frame 111. The front side of the sub-frame 114 is connected to the connecting plate 1112, and the first insertion portion 241 is connected to the connecting plate 1112. The first insertion portion 241 is provided close to the front side of the sub-frame 114. Through the above settings, the sub-frame 114 and the saddle assembly 24 are simultaneously connected to the connecting plate 1112, which can reduce the number of connection points on the main frame 111, which is beneficial to improving the utilization rate of the main frame 111. At the same time, it can avoid the distance between the sub-frame 114 and the saddle assembly 24 from being too large, which is beneficial to improving the space utilization rate of the motorcycle 100.

[0045] As an implementation, when observing along the height direction of the motorcycle 100, the first plug-in part 1111 is located inside the main frame 111, and the second plug-in parts 1143 are all located inside the sub-frame 114. Through the above arrangement, by setting the first plug-in part 1111 and the second plug-in parts 1143 inside the frame 11, it can be avoided that the legs of the driver are scratched due to the exposure of the first plug-in part 1111 or the second plug-in parts 1143, which is beneficial to improving the driving experience of the motorcycle 100. At the same time, it can also avoid the waste of the body space caused by the over-wide width of the saddle assembly 24, and thus is also beneficial to improving the space utilization rate of the motorcycle 100.

[0046] As Figure 6 and Figure 7 shown, as an implementation, the body covering part 12 includes connecting guards 127 located on both sides of the main frame 111. The power system 15 includes an engine 151. The electrical system 23 includes a rectifier-regulator 239 electrically connected to the engine 151. The rectifier-regulator 239 is used to receive the alternating current generated by the engine 151, rectify it and then deliver it to the electrical devices or batteries of the motorcycle 100. The motorcycle 100 further includes a heat dissipation assembly 28. The heat dissipation assembly 28 includes a radiator 281. The radiator 281 is located in front of the engine 151. The body covering part 12 includes a diversion housing 201 at least partially disposed in front of the connecting guard 127. The diversion housing 201 is fixedly connected to the main frame 111. The diversion housing 201 forms a heat dissipation cavity 2011 for air circulation. The rectifier-regulator 239 is fixedly disposed on the diversion housing 201 and is located in the heat dissipation cavity 2011. An air inlet 2012 for air to enter the heat dissipation cavity 2011 is provided in front of the diversion housing 201. When observing from the length direction of the motorcycle 100, the air inlet 2012 at least partially overlaps with the rectifier-regulator 239. In the prior art, the rectifier-regulator 239 is usually located at the rear of the motorcycle 100, and the eddy currents generated by the air flows on both sides when the motorcycle 100 is running are used to take away the heat generated by the rectifier-regulator 239. However, due to the slow flow rate of the eddy currents generated by the air on both sides, the heat dissipation effect of the rectifier-regulator 239 is poor. In the implementation manner of the present application, air can directly enter the air inlet 2012 and pass through the rectifier-regulator 239 to take away the heat generated by the rectifier-regulator 239. Through the above arrangement, the heat dissipation capacity of the rectifier-regulator 239 is improved.

[0047] Specifically, when observed from the height direction of the motorcycle 100, the rectifier regulator 239 is located in front of the radiator 281. Along the length direction of the motorcycle 100, the distance L1 between the rectifier regulator 239 and the radiator 281 is greater than or equal to 110 mm and less than or equal to 130 mm. Further, the distance L1 between the rectifier regulator 239 and the radiator 281 is greater than or equal to 115 mm and less than or equal to 125 mm. More preferably, the distance L1 between the rectifier regulator 239 and the radiator 281 is equal to 120 mm. If the distance between the rectifier regulator 239 and the radiator 281 is too large, since the radiator 281 is located in front of the engine 151, the distance between the rectifier regulator 239 and the engine 151 is relatively far, which in turn leads to a longer connection wire harness 2391 between the rectifier regulator 239 and the engine 151, thus increasing the production cost of the motorcycle 100. If the distance between the rectifier regulator 239 and the radiator 281 is too small, due to the high heat of the radiator 281, the heat dissipation capacity of the rectifier regulator 239 will be affected. Through the above settings, while ensuring the heat dissipation capacity of the rectifier regulator 239, the production cost of the motorcycle 100 can also be reduced.

[0048] As an implementation manner, an air outlet 2013 for the air in the heat dissipation cavity 2011 to flow out is provided on the diversion housing 201. A wind channel 2014 extending from the air inlet 2012 to the air outlet 2013 is formed in the heat dissipation cavity 2011. The rectifier regulator 239 is located in the wind channel 2014, so that air can enter from the air inlet 2012, flow through the rectifier regulator 239, and then flow out from the air outlet 2013, thereby improving the heat dissipation capacity of the rectifier regulator 239.

[0049] Since the outer surface of the diversion housing 201 is an uneven surface, in order to fix the rectifier regulator 239, a fixing surface 2015 for fixing the rectifier regulator 239 is formed on one side of the diversion housing 201 close to the heat dissipation cavity 2011. The rectifier regulator 239 is fixed to the fixing surface 2015 through fasteners, and the fixing surface 2015 is a flat surface. Through the above settings, the connection stability between the rectifier regulator 239 and the diversion housing 201 is improved.

[0050] As an implementation manner, a wire harness fixing member 1115 is provided on the main frame 111. The wire harness fixing member 1115 is used to fix the connection wire harness 2391 between the rectifier regulator 239 and the engine 151. Since the temperature of the radiator 281 is relatively high, the above settings can prevent the connection wire harness 2391 from interfering with the radiator 281 and causing damage to the connection wire harness 2391. Through the above settings, the safety of the connection wire harness 2391 is improved.

[0051] Such as Figure 8As shown, as an implementation, the rectifier regulator 239 includes a wiring harness connection port 2392. The wiring terminal of the wiring harness connection port 2392 basically faces the engine 151, and the wiring terminal of the wiring harness connection port 2392 is inclined downward toward the lower part of the motorcycle 100. By providing the wiring harness connection port 2391 facing the engine 151, the length of the wiring harness 2391 connecting the rectifier regulator 239 and the engine 151 can be reduced, thereby reducing the production cost of the whole vehicle. In addition, the wiring terminal of the wiring harness connection port 2392 being inclined downward toward the lower part of the motorcycle 100 can also prevent liquids such as rainwater or dew from flowing into the wiring harness connection port 2392 along the wiring harness 2391, thereby improving the safety of the wiring harness connection port 2392.

[0052] As Figure 6 and Figure 8 As shown, as an implementation, the flow guide housing 201 includes at least one housing fixing part 2016. The housing fixing part 2016 is provided at the lower end of the flow guide housing 201. The housing fixing part 2016 fixes the flow guide housing 201 to the main frame 111 through fasteners, and the fasteners are exposed. A first clamping part 2017 is provided on one side of the flow guide housing 201 close to the connecting guard plate 127, and a second clamping part 1271 that is clamped with the first clamping part 2017 is provided on the connecting guard plate 127. The flow guide housing 201 is detachably connected to the connecting guard plate 127 through the first clamping part 2017. Through the above settings, in the case where the rectifier regulator 239 is damaged, after removing the fasteners in the housing fixing part 2016 and separating the first clamping part 2017 from the second clamping part 1271, the flow guide housing 201 can be separated from the connecting guard plate 127, and then the rectifier regulator 239 can be removed from the flow guide housing 201, thereby reducing the disassembly difficulty of the rectifier regulator 239 and improving the maintenance convenience of the rectifier regulator 239. In addition, clamping the flow guide housing 201 and the connecting guard plate 127 can also reduce the number of required fasteners, thereby reducing the connection difficulty between the flow guide housing 201 and the connecting guard plate 127.

[0053] As Figure 9 As shown, as an implementation, the motorcycle 100 further includes an air filter assembly 29. The air filter assembly 29 includes an air filter 291. At least part of the air filter 291 is provided on the sub-frame 114 and is fixedly connected to the sub-frame 114. A first air filter fixing part 1145 extending in the width direction of the motorcycle 100 is provided on the sub-frame 114. The first air filter fixing part 1145 is integrally formed with the sub-frame 114. The first air filter fixing part 1145 abuts against the air filter 291 in the width direction of the motorcycle 100 to fix the air filter 291.

[0054] It should be noted that in the prior art, the air filter 291 is usually placed in the subframe 114 after the assembly of the subframe 114 is completed, and then the first air filter fixing part 1145 is fixedly connected to the subframe 114 to fix the air filter 291. In the embodiment of the present application, the first air filter fixing part 1145 is integrally formed with the subframe 114. During the connection process between the air filter 291 and the subframe 114, the air filter 291 is first placed between the subframes 114 on both sides, and then the subframes 114 on both sides are fixedly connected to each other so that the first fixing part abuts against the air filter 291 to fix the air filter 291, thus eliminating the need to place the air filter 291 in the subframe 114 after the frame installation is completed. Compared with the prior art, the embodiment of the present application can increase the volume of the air filter 291, thereby improving the intake efficiency of the air filter 291.

[0055] Specifically, the air filter 291 includes a first part 2911 and a second part 2912 arranged along the height direction of the motorcycle 100, and the second part 2912 is located below the first part 2911. The upper main pipes 1141 extend along the length direction of the motorcycle 100 and are arranged in pairs. At the front end of the upper main pipes 1141, that is, the part of the upper main pipes 1141 that clamps the air filter 291, the spacing in the width direction of the motorcycle 100 is smaller than the maximum length of the second part 2912 of the air filter 291 extending in the width direction of the motorcycle 100. In the prior art, during the assembly process of the air filter 291, after the subframes 114 on the left and right sides are assembled, the air filter 291 needs to be placed between the subframes 114. Therefore, the width of the second part 2912 of the air filter 291 in the width direction of the motorcycle 100 is relatively small in the prior art. In the embodiment of the present application, by assembling the air filter 291 with the subframes 114 on both sides simultaneously, the width of the second part 2912 in the width direction of the motorcycle 100 is increased, thereby increasing the volume of the air filter 291 and improving the intake efficiency of the air filter 291.

[0056] As an implementation manner, the air filter 291 includes a second air filter fixing part 2913, and the first air filter fixing part 1145 is fitted into the second air filter fixing part 2913 to fix the air filter 291. The air filter 291 further includes a buffer member 2914 located between the first air filter fixing part 1145 and the second air filter fixing part 2913, and both sides of the buffer member 2914 abut against the first air filter fixing part 1145 and the second air filter fixing part 2913 respectively. The buffer member 2913 can be set as an elastic member such as a rubber pad. Through the above settings, while improving the fixing strength of the first air filter fixing part 1145, it can also reduce the noise generated by the collision between the first air filter fixing part 1145 and the second air filter fixing part 2913, thereby improving the use experience of the rider.

[0057] As an implementation, the subframe 114 includes an air filter support 1146 located below the air filter 291. The air filter support 1146 supports the air filter 291 in the height direction of the motorcycle 100 and is fixedly connected to the air filter 291 through fasteners, thereby restricting the movement of the air filter 291 in the height direction of the motorcycle 100 and improving the connection stability between the air filter 291 and the frame.

[0058] As Figure 10 shown, as an implementation, the air filter assembly 29 further includes an intake air temperature sensor 292. The intake air temperature sensor 292 is fixedly arranged on the first part 2911 and penetrates through the first part 2911 in the length direction of the motorcycle 100. Since the intake air duct 2915 of the air filter 291 extends in the length direction of the motorcycle 100, arranging the intake air temperature sensor 292 to penetrate through the first part 2911 in the length direction of the motorcycle 100 can increase the contact area between the intake air temperature sensor 292 and the intake air duct 2915, thereby improving the accuracy of the intake air temperature sensor 292 during detection.

[0059] Furthermore, a receiving groove 2911a for receiving the intake air temperature sensor 292 is formed on the first part 2911. In the height direction of the motorcycle 100, the height of the receiving groove 2911a is greater than the height of the intake air temperature sensor 292, thereby avoiding interference between the intake air temperature sensor 292 and the seat cushion (not shown in the figure) above the first part 2911, and thus improving the usage stability of the intake air temperature sensor 292.

[0060] Even further, a notch 2911b is formed in the receiving groove 2911a in the direction towards the subframe 114, and the receiving groove 2911a communicates with the outside through the notch 2911b. When the motorcycle 100 is running in rainy weather, rainwater can accumulate in the receiving groove 2911a, resulting in damage to the intake air temperature sensor 292 in the receiving groove 2911a. Through the above arrangement, the rainwater can flow out from the notch 2911b, thereby improving the safety of the intake air temperature sensor 292.

[0061] Preferably, the notch 2911b is located on the left side of the longitudinal plane 101. Since the side stand of the motorcycle 100 is basically located on the left side of the motorcycle 100, the body of the motorcycle 100 tilts to the left when the motorcycle 100 is parked. Through the above arrangement, it is possible to avoid damage to the intake air temperature sensor 292 caused by rainwater accumulating in the receiving groove 2911a when the motorcycle 100 is parked, thereby extending the service life of the intake air temperature sensor 292.

[0062] It should be understood that for those of ordinary skill in the art, improvements or changes can be made according to the above description, and all such improvements and changes should fall within the protection scope of the appended claims of this application.
