[0030] The present application provides a motorcycle 100 as shown in FIG1 . The motorcycle 100 includes a frame 11, a body panel 12, a suspension assembly 13, a running assembly 14, and a power system 15. The body panel 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 via the suspension assembly 13. The power system 15 is at least partially disposed on the frame 11 and 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. To clearly illustrate the technical solution of the application, the front, rear, left, right, top, and bottom are also defined as shown in FIG1 . In the present application, the length direction of the motorcycle 100 refers to the aforementioned front-to-back direction, the width direction of the motorcycle 100 refers to the aforementioned left-to-right direction, and the height direction of the motorcycle 100 refers to the aforementioned up-down direction.

[0031] As shown in Figures 2 and 3 , as one implementation, the motorcycle 100 further includes a fuel tank 22. The fuel tank 22 is disposed at least partially around and connected to the frame 11, and is used to store fuel for the motorcycle 100. The body panel 12 includes fuel tank guards 122 and connecting plates 123 located on the left and right sides of the motorcycle 100. The connecting plates 123 are located between the fuel tank 22 and the fuel tank guards 122. The connecting plates 123 are detachably connected to the fuel tank 22 and engage with the fuel tank guards 122, thereby enabling the fuel tank guards 122 to be detachably connected to the fuel tank 22 via the connecting plates 123. Specifically, the connecting plates 123 are substantially rectangular parallelepiped structures extending in the front-to-rear direction of the motorcycle 100. One side of the connecting plate 123 is detachably connected to the fuel tank 22, and the other side of the connecting plate 123 engages with the inner side of the fuel tank guard 122. Through the above arrangement, the fuel tank guard plate 122 can be quickly removed from the connecting plate 123, while avoiding the need for multiple connection points between the fuel tank 22 and the fuel tank guard plate 122. This simplifies the connection structure between the fuel tank 22 and the fuel tank guard plate 122, thereby facilitating improved assembly efficiency of the fuel tank 22 and the fuel tank guard plate 122. It should be noted that when the fuel tank guard plate 122 is impacted by an external force, the fuel tank guard plate 122 can be quickly removed from the connecting plate 123, thereby minimizing the impact of the external force on the fuel tank 22, thereby facilitating improved service life of the fuel tank 22. The number of connecting plates 123 can be set according to actual conditions to ensure the stability of the connection between the fuel tank 22 and the fuel tank guard plate 122.

[0032] As an implementation, the fuel tank guard plate 122 includes a left fuel tank guard plate 1221 and a right fuel tank guard plate 1222. The left fuel tank guard plate 1221 is connected to the left side of the fuel tank 22 via a connecting plate 123, and the right fuel tank guard plate 1222 is connected to the right side of the fuel tank 22 via a connecting plate 123. Through the above arrangement, the left fuel tank guard plate 1221 and the right fuel tank guard plate 1222 respectively protect the left and right sides of the fuel tank 22, thereby facilitating improved safety performance of the fuel tank 22.

[0033] As an implementation, the fuel tank 22 is provided with a connecting portion 221, which is located at the upper end of the fuel tank 22. The connecting plate 123 is at least partially engaged with the connecting portion 221, and the upper end of the fuel tank guard 122 is connected to the connecting portion 221 via the connecting plate 123. Specifically, the fuel tank 22 is at least partially recessed inward to form the connecting portion 221, which is precisely adapted to engage with the connecting plate 123, thereby making the connection between the connecting plate 123 and the fuel tank 22 more stable, thereby improving the structural stability of the connecting plate 123 and the fuel tank 22.

[0034] As an implementation, the connecting plate 123 and the fuel tank 22 at least partially overlap when viewed across the width and height of the motorcycle 100. Specifically, the lower side of the connecting plate 123 at least partially abuts the fuel tank 22, and the left or right side of the connecting plate 123 at least partially abuts the fuel tank 22. This arrangement allows the fuel tank 22 to provide support for the connecting plate 123, further stabilizing the connection between the connecting plate 123 and the fuel tank 22. This improves the stability of the connection between the connecting plate 123 and the fuel tank 22, while also making the structure of the connecting plate 123 and the fuel tank 22 more compact and enhancing the structural compactness of the connecting plate 123 and the fuel tank 22.

[0035] As an implementation, the fuel tank 22 is provided with a threaded hole 2211, and the connecting plate 123 is provided with a through hole 1231 corresponding to the threaded hole 2211. A fastener can be passed through the through hole 1231 and then connected to the threaded hole 2211, thereby detachably connecting the connecting plate 123 to the fuel tank 22. This arrangement provides a stable connection between the connecting plate 123 and the fuel tank 22, and the bolts can be sunk into the connecting plate 123, thereby avoiding interference with the assembly of the fuel tank guard plate 122. This facilitates improved assembly of the connecting plate 123, the fuel tank 22, and the fuel tank guard plate 122.

[0036] As an implementation, the fuel tank guard plate 122 is provided with a snap-fitting groove 1223 and a clamping plate 1224. The connecting plate 123 is provided with a snap-fitting portion 1232 corresponding to the snap-fitting groove 1223 and a clamping portion 1233 corresponding to the clamping plate 1224. The snap-fitting portion 1232 is snap-fitted into the snap-fitting groove 1223, and a clamping gap 1234 is formed between the clamping portion 1233 and the connecting plate 123. The clamping plate 1224 is positioned within the clamping gap 1234, thereby snapping the connecting plate 123 into engagement with the fuel tank guard plate 122. With this arrangement, the clamping plate 1224 can limit the vertical movement of the clamping portion 1233, while the snap-fitting portion 1232 can limit the horizontal and forward and backward displacement of the snap-fitting groove 1223, thereby making the connection between the fuel tank guard plate 122 and the connecting plate 123 more stable, thereby facilitating improved stability of the connecting plate 123, the fuel tank 22, and the fuel tank guard plate 122. It should be noted that the connection strength between the fuel tank guard plate 122 and the connecting plate 123 is smaller than the connection strength between the connecting plate 123 and the fuel tank 22 , thereby better protecting the fuel tank 22 .

[0037] As an implementation method, the fuel tank 22 is further provided with a support portion 222, which is substantially located at the lower end of the fuel tank 22, and the lower end of the fuel tank guard 122 abuts against the support portion 222. Specifically, since the volume and mass of the fuel tank guard 122 are relatively large, the support portion 222 is provided at the lower end of the fuel tank 22 to provide an upward supporting force for the fuel tank guard 122, thereby preventing the motorcycle 100 from being shaken due to poor road conditions during driving and affecting the connection stability of the fuel tank guard 122. At the same time, the connecting plate 123 can cooperate with the support portion 222 to limit the upward and downward movement of the fuel tank guard 122, thereby facilitating the stability of the connecting plate 123, the fuel tank 22, and the fuel tank guard 122.

[0038] As shown in FIG3 , as one implementation, the connecting plate 123 extends substantially along the length of the motorcycle 100, and the ratio of the maximum length L1 of the connecting plate 123 along the length of the motorcycle 100 to the maximum length L2 of the fuel tank guard 122 along the length of the motorcycle 100 ranges from 0.1 to 0.7. Specifically, the ratio of the maximum length L1 of the connecting plate 123 along the length of the motorcycle 100 to the maximum length L2 of the fuel tank guard 122 along the length of the motorcycle 100 ranges from 0.2 to 0.5. More specifically, the ratio of the maximum length L1 of the connecting plate 123 along the length of the motorcycle 100 to the maximum length L2 of the fuel tank guard 122 along the length of the motorcycle 100 is set to 0.3. Through the above-mentioned arrangement, it is possible to avoid the length of the fuel tank guard plate 122 being too short due to the ratio of the maximum length L1 of the connecting plate 123 along the length direction of the motorcycle 100 to the maximum length L2 of the fuel tank guard plate 122 along the length direction of the motorcycle 100 being too large, thereby preventing the protection performance of the fuel tank guard plate 122 from being reduced, which is beneficial to improving the protection performance of the fuel tank guard plate 122; it is also possible to avoid the length of the connecting plate 123 being too short due to the ratio of the maximum length L1 of the connecting plate 123 along the length direction of the motorcycle 100 to the maximum length L2 of the fuel tank guard plate 122 along the length direction of the motorcycle 100 being too small, thereby preventing the connection stability of the connecting plate 123 from being reduced, thereby beneficial to improving the connection stability of the connecting plate 123, the fuel tank 22 and the fuel tank guard plate 122.

[0039] As shown in FIG4 , the vehicle body panel 12 also includes an electrical appliance fixing plate 124, which is connected to the vehicle frame 11. A positioning hole 1225 is provided on the rear side of the fuel tank guard 122, and a fixing hole 1241 is provided on the electrical appliance fixing plate 124, which corresponds to the positioning hole 1225. Fasteners are inserted through the positioning hole 1225 and the fixing hole 1241 to connect the fuel tank guard 122 to the vehicle frame 11 via the electrical appliance fixing plate 124. Specifically, the electrical appliance fixing plate 124 is used to fix various electrical switches and / or controllers. The electrical appliance fixing plate 124 is located at the rear end of the fuel tank guard 122, and the fuel tank guard 122 is connected to both sides of the electrical appliance fixing plate 124, thereby improving the connection stability of the rear side of the fuel tank guard 122.

[0040] As an implementation method, the fuel tank 22 includes an oil leak pan 223, and the connecting plate 123 is located on both sides of the oil leak pan 223. The body cover 12 also includes an upper guard plate 125. The front side of the upper guard plate 125 is clamped with the fuel tank 22, the left side of the upper guard plate 125 is clamped with the left guard plate 1221 of the fuel tank, and the right side of the upper guard plate 125 is clamped with the right guard plate 1222 of the fuel tank. The upper guard plate 125 is located on the rear side of the oil leak pan 223, and the upper guard plate 125 is located on the upper side of the electrical fixing plate 124. Specifically, the upper guard plate 125 is used to connect the left guard plate 1221 and the right guard plate 1222 of the fuel tank, so that the left guard plate 1221 and the right guard plate 1222 of the fuel tank are connected left and right to improve the stability of the left guard plate 1221 and the right guard plate 1222 of the fuel tank. At the same time, the upper guard plate 125 is clamped with the fuel tank guard plate 122, which is beneficial to improve the assembly efficiency of the upper guard plate 125 and the fuel tank guard plate 122.

[0041] As shown in Figures 5 and 6, as one implementation, the fuel tank 22 includes a tank body 224, with an oil drain pan 223 located substantially at the upper end of the tank body 224 and connected thereto. Specifically, the tank body 224 is used to store fuel, while the oil drain pan 223 is used to add fuel and drain any fuel or oil vapor that overflows from the tank. More specifically, the oil drain pan 223 is provided with an oil drain pipe 225 and an air drain pipe 226. Both the oil drain pipe 225 and the air drain pipe 226 are connected to the oil drain pan 223. The oil drain pipe 225 and the air drain pipe 226 at least partially penetrate the oil drain pan 223, so that the oil drain pipe 225 and the air drain pipe 226 are at least partially located outside the oil drain pan 223. The oil drain pan 223 forms an oil pan space 103 around the oil drain pan 223, and the oil drain pipe 225 connects the oil pan space 103 with the outside world. The fuel in the oil leakage pan 223 flows out of the fuel tank body 224 through the oil leakage pipe 225, and the oil and gas in the fuel tank body 224 flows out of the fuel tank body 224 through the air leakage pipe 226. This arrangement allows the air leakage pipe 226 and the oil leakage pipe 225 to be located outside the fuel tank body 224, simplifying the structure of the fuel tank body 224. This helps increase the fuel storage capacity of the fuel tank body 224 and, in turn, improves the endurance of the motorcycle 100. This also facilitates the discharge of the fuel in the oil leakage pan 223 and the oil and gas in the fuel tank body 224. Furthermore, the placement of the oil leakage pipe 225 and the air leakage pipe 226 outside the oil leakage pan 223 facilitates assembly and maintenance of the oil leakage pipe 225 and the air leakage pipe 226, thereby improving the assembly efficiency of the fuel tank 22. In addition, when rainwater from the outside flows into the oil leakage pan 223, it can be directly discharged to the outside of the oil leakage pan 223 through the oil leakage pipe 225 to avoid entering the fuel tank body 224, which is beneficial to protecting the quality of the fuel in the fuel tank body 224 and further beneficial to improving the working stability of the motorcycle 100.

[0042] As one implementation, the fuel tank 22 includes multiple rubber hoses 227 located outside the fuel tank body 224. The rubber hoses 227 include a first rubber hose 2271, which is connected to the oil leakage pipe 225 and extends at least partially in the vertical direction of the motorcycle 100. Specifically, the upper end of the first rubber hose 2271 is connected to the oil leakage pipe 225, and the lower end of the first rubber hose 2271 is located below the fuel tank body 224. This arrangement allows liquid in the oil leakage pan 223 to flow directly to the ground through the oil leakage pipe 225 and the first rubber hose 2271, preventing fuel or rainwater from sliding off the fuel tank body 224. This improves the cleanliness of the motorcycle 100 and prevents fuel or rainwater from coming into contact with the driver, thereby enhancing the driving experience of the motorcycle 100.

[0043] In this embodiment, the motorcycle 100 includes a carbon canister 25, which is at least partially connected to the underside of the fuel tank body 224. The rubber hose 227 includes a second rubber hose 2272, which is connected to the air leakage pipe 226. The second rubber hose 2272 extends at least partially in the vertical direction of the motorcycle 100. Specifically, the upper end of the second rubber hose 2272 is connected to the air leakage pipe 226, and the lower end of the second rubber hose 2272 is connected to the carbon canister 25. The air leakage pipe 226 connects the interior of the fuel tank body 224 with the carbon canister 25. This arrangement allows the fuel and gas in the fuel tank body 224 to flow directly into the carbon canister 25 through the air leakage pipe 226 and the second rubber hose 2272, preventing the fuel and gas from escaping into the atmosphere and causing environmental pollution. This improves environmental protection and promotes green travel. In addition, the rubber hose 227 includes a third rubber hose 2273, and the power system 15 includes an engine 151 (see Figure 1). One end of the third rubber hose 2273 is connected to the carbon canister 25, and the other end of the third rubber hose 2273 is connected to the engine 151, so that the oil and gas can be directly supplied to the engine 151 after being processed by the carbon canister 25, which is beneficial to the recycling of oil and gas, and further beneficial to improving the working efficiency of the engine 151.

[0044] As an implementation, the fuel tank body 224 is at least partially recessed inward to form an annular groove 2241, and the oil drain pan 223 is detachably mounted within the annular groove 2241 via fasteners. Specifically, the annular groove 2241 is configured to receive the oil drain pan 223, allowing the oil drain pan 223 to collect fuel and rainwater, thereby improving the operating efficiency of the oil drain pan 223.

[0045] As an implementation, a fuel tank opening 2242 is defined on the upper side of the fuel tank body 224. An oil leak pan 223 is disposed at the fuel tank opening 2242 and connected to the fuel tank body 224. An annular groove 2241 is provided around the fuel tank opening 2242. The oil leak pan 223 includes an oil filling port 2231, which is at least partially located within the fuel tank opening 2242, thereby establishing electrical communication between the oil leak pan 223 and the fuel tank body 224. Specifically, the oil filling port 2231 engages with the fuel tank opening 2242, allowing fuel to be injected into the fuel tank body 224 through the oil filling port 2231, thereby filling the fuel tank 22. Furthermore, the contact surfaces of the fuel tank opening 2242 and the oil filling port 2231 are tightly fitted to prevent the fuel in the fuel tank body 224 from flowing out, thereby improving the sealing performance of the fuel tank 22. At the same time, during the refueling process, fuel leakage can be directly collected by the oil leakage pan 223, which is beneficial to improving the cleanliness of the fuel tank 22.

[0046] In this embodiment, the fuel tank 22 further includes a fuel tank cap 228. The fuel tank cap 228 is at least partially located above the oil leak pan 223. The fuel tank cap 228 is used to seal the fuel filling port 2231. Specifically, the fuel tank cap 228 and the oil leak pan 223 are detachably connected. When the fuel tank 22 needs to be refueled, the fuel tank cap 228 can be opened to refuel the fuel tank 22. When the fuel in the fuel tank 22 is fully replenished, the fuel tank cap 228 can seal the fuel filling port 2231 to prevent fuel from flowing out of the fuel filling port 2231, thereby improving the sealing performance of the fuel tank 22.

[0047] As an implementation, the fuel tank cap 228 is provided with a plurality of first through-holes 2281, the oil drain pan 223 is provided with a plurality of second through-holes 2232, and the fuel tank body 224 is provided with a plurality of threaded holes 2243. The first through-holes 2281, the second through-holes 2232, and the threaded holes 2243 are coaxially arranged, so that the fuel tank cap 228 and the oil drain pan 223 are detachably connected to the fuel tank body 224 via bolts. This arrangement improves the connection stability between the fuel tank cap 228, the oil drain pan 223, and the fuel tank body 224, avoids excessive connection points, and thus improves the assembly efficiency of the fuel tank 22. It should be noted that the fuel tank cap 228 includes a connecting portion and a disassembly portion. The disassembly portion is detachably connected to the connecting portion, which is connected to the oil drain pan 223 and the fuel tank body 224. During refueling of the motorcycle 100, the disassembly portion can be quickly removed from the connecting portion, thereby improving the refueling speed of the motorcycle 100.

[0048] As an implementation, the fuel tank cap 228 is provided with an oil and gas passage (not shown) communicating with the fuel tank opening 2242. The oil drain pan 223 is provided with a vent 2233 connecting the oil and gas passage and the leak pipe 226. The vent 2233 is connected to the carbon canister 25 via the leak pipe 226 and a rubber hose 227, allowing the oil and gas within the fuel tank body 224 to be discharged into the carbon canister 25. Through this arrangement, the oil and gas within the fuel tank body 224 flow sequentially through the oil and gas passage, the vent 2233, the leak pipe 226, and the rubber hose 227 to discharge the oil and gas within the fuel tank body 224, thereby improving fuel utilization. It should be noted that the oil and gas passage can only discharge oil and gas when the motorcycle 100 is parked or driving normally. When the motorcycle 100 is tipped over, the oil and gas passage automatically closes, preventing fuel leakage and improving the sealing performance of the fuel tank 22.

[0049] In this embodiment, the oil pan 223 is further provided with an oil drain hole 2234 that communicates with the oil pan space 103. This drain hole 2234 is connected to an oil drain pipe 225, allowing the liquid in the oil pan 223 to be discharged to the outside. This arrangement allows fuel or rainwater to flow sequentially through the oil drain hole 2234, the oil drain pipe 225, and the rubber hose 227 to clean the oil pan 223, thereby improving the cleanliness of the motorcycle 100.

[0050] As shown in FIG7 , as one implementation, the frame 11 includes a main frame 111 and a subframe 114 distributed along the length of the motorcycle 100. The main frame 111 is substantially located in front of the subframe 114 and is connected to the subframe 114. The motorcycle 100 includes a battery 26. The battery 26 and the fuel tank 22 are both at least partially located on the upper side of the main frame 111 and connected to the main frame 111. The motorcycle 100 includes a saddle assembly 24 (see FIG1 ). The saddle assembly 24 is located on the upper side of the subframe 114 and is connected to the subframe 114. A fuel tank opening 229 is formed around the rear side of the fuel tank 22. The battery 26 is at least partially located within the fuel tank opening 229. Along the length of the motorcycle 100, the battery 26 is at least partially located between the fuel tank 22 and the saddle assembly 24. Through the above arrangement, the battery 26 is integrated into the rear side of the fuel tank 22, which can make the structure of the battery 26 and the fuel tank 22 more compact, and make full use of the free space on the rear side of the fuel tank 22, thereby helping to improve the structural compactness of the motorcycle 100. At the same time, the fuel tank 22 is at least partially arranged around the battery 26, which can also protect the battery 26 and thus help to extend the service life of the battery 26.

[0051] As an implementation, the motorcycle 100 includes an electrical system 23, which includes a controller 235, a relay 236 and an electrical connector 237. The controller 235, the relay 236 and the electrical connector 237 are fixedly connected to the main frame 111, and the controller 235, the relay 236 and the electrical connector 237 are located between the battery 26 and the saddle assembly 24. The controller 235, the relay 236 and the electrical connector 237 are all electrically connected to the battery 26 via a wiring harness. Specifically, the controller 235, the relay 236 and the electrical connector 237 are integrated into the rear side of the battery 26 so that the controller 235, the relay 236 and the electrical connector 237 are arranged close to the battery 26, which is beneficial to shorten the length of the wiring harness to improve the space utilization of the motorcycle 100. At the same time, when observed along the height direction of the motorcycle 100, the controller 235, the relay 236, the electrical connector 237 and the battery 26 at least partially overlap, so that the structure of the controller 235, the relay 236, the electrical connector 237 and the battery 26 is more compact, which is beneficial to improve the structural compactness of the motorcycle 100.

[0052] As an implementation, the battery 26, controller 235, relay 236, and electrical connector 237 are all located above the engine 151. The battery 26 and engine 151 are electrically connected via a wiring harness. Specifically, the battery 26 provides electrical energy to the engine 151, enabling it to start. This placement of the battery 26 above the engine 151 reduces the distance between the engine 151 and the battery 26, thereby making the structure of the engine 151 and battery 26 more compact. It also helps shorten the wiring harness, thereby improving the efficiency of electrical energy transfer between the battery 26 and the engine 151.

[0053] As an implementation, the left and right fuel tank guard plates 1221, 1222 are arranged along the width of the motorcycle 100 and connected to the fuel tank 22. The battery 26 is at least partially located between the left and right fuel tank guard plates 1221, 1222. The electrical fixture plate 124 is located behind the battery 26 and connected to the main frame 111. The electrical fixture plate 124 is used to secure the controller 235, the relay 236, and the electrical connector 237. The left and right fuel tank guard plates 1221, 1222 are connected to either side of the electrical fixture plate 124. Specifically, the left and right fuel tank guard plates 1221, 1222 are used to protect the battery 26, the controller 235, the relay 236, and the electrical connector 237, thereby improving the safety of the battery 26, the controller 235, the relay 236, and the electrical connector 237. In addition, the left tank guard plate 1221 and the right tank guard plate 1222 are clamped on the fuel tank 22. When the battery 26, the controller 235, the relay 236 or the electrical connector 237 need to be repaired, the left tank guard plate 1221 and / or the right tank guard plate 1222 can be directly removed from the fuel tank 22 to facilitate the installation and maintenance of the battery 26, the controller 235, the relay 236 or the electrical connector 237, which is beneficial to improve the assembly performance of the motorcycle 100.

[0054] As an implementation, the upper guard plate 125 is located above the battery 26, and the left and right fuel tank guard plates 1221 and 1222 connect to either side of the upper guard plate 125. Specifically, the upper guard plate 125 covers the upper side of the battery 26, controller 235, relay 236, and electrical connector 237, thereby preventing rainwater and other substances from falling onto the surfaces of the battery 26, controller 235, relay 236, and electrical connector 237 and affecting their normal operation, thereby facilitating the improvement of the service life of the battery 26, controller 235, relay 236, and electrical connector 237. In addition, the upper guard plate 125 is connected to the left guard plate 1221 and the right guard plate 1222 of the fuel tank. When the battery 26, the controller 235, the relay 236 or the electrical connector 237 need to be repaired, the upper guard plate 125 can be directly removed, and the battery 26, the controller 235, the relay 236 or the electrical connector 237 can be installed and repaired, which is beneficial to improving the assembly performance of the motorcycle 100.

[0055] As shown in FIG8 , as one implementation, the vehicle body panel 12 further includes a battery box 120. The vehicle frame 11 includes a fixing plate 1113. The fixing plate 1113 is located on the inner side of the main frame 111 and is connected to the main frame 111. The battery box 120 is fixedly connected to the fixing plate 1113, and the battery 26 is at least partially located within the battery box 120. Specifically, at least three fixing plates 1113 are provided on the main frame 111. The bottom of the battery box 120 connects to corresponding connecting portions of the fixing plates 1113. The fixing plates 1113 can be detachably connected to the connecting portions via fasteners, thereby stably connecting the battery box 120 to the main frame 111, thereby stably installing the battery 26 within the battery box 120, thereby facilitating improved safety of the battery 26.

[0056] As an implementation method, an electrical lower guard plate 1201 is provided on the battery box 120. The electrical lower guard plate 1201 and the battery box 120 are integrated. The electrical fixing plate 124 is located on the upper side of the electrical lower guard plate 1201 and is connected to the electrical lower guard plate 1201. Specifically, the electrical lower guard plate 1201 is connected to the main frame 111, and the controller 235 is provided between the electrical lower guard plate 1201 and the electrical fixing plate 124. The electrical lower guard plate 1201 is used to protect the controller 235, thereby facilitating the extension of the service life of the controller 235. At the same time, the relay 236 and the electrical connector 237 are located on the upper side of the controller 235, that is, the controller 235, the relay 236 or the electrical connector 237 are arranged in a stacked manner, thereby facilitating the improvement of the structural compactness of the electrical system 23 and the improvement of the space utilization rate of the motorcycle 100.

[0057] As an implementation, the battery case 120 is further provided with a battery pressure plate 1202, which is detachably connected to the battery case 120. The battery pressure plate 1202 is made of plastic and at least partially surrounds the battery 26. Specifically, the battery pressure plate 1202 is used to limit the movement of the battery 26, preventing the battery 26 from moving up and down within the battery case 120, thereby improving the connection stability between the battery case 120 and the battery 26. Furthermore, the plastic battery pressure plate 1202 is non-conductive, preventing the battery 26 from short-circuiting due to the battery pressure plate 1202 contacting the positive and negative electrodes, thereby improving the service life of the battery 26.

[0058] As an implementation, the battery 26 includes a positive terminal 261, and the vehicle body cover 12 includes a positive protective cover 1203. The positive protective cover 1203 covers the positive terminal 261 and is engaged with the positive terminal 261. Specifically, positioning the positive protective cover 1203 at the positive terminal 261 of the battery 26 prevents the positive terminal of the battery 26 from contacting the frame 11. Since the frame 11 is made of metal, radio interference would be generated when the positive terminal of the battery 26 is connected to the frame 11. Therefore, the positive terminal 261 needs to be protected. In this embodiment, the positive protective cover 1203 is made of plastic to prevent the positive terminal 261 from connecting to the frame 11, thereby protecting the normal operation of the battery 26 and improving the operating stability of the motorcycle 100.

[0059] As shown in Figures 1, 9, and 10, as one implementation, the fuel tank 22 at least partially surrounds the outside of the main frame 111 and is connected to the main frame 111. Fuel tank guards 122 are located on the left and right sides of the motorcycle and are connected to the fuel tank 22. The fuel tank guards 122 are formed with first air guides 1226. The fuel tank 22 is at least partially exposed on the left and right sides of the motorcycle 100, and second air guides 1227 are formed on the left and right sides. The first air guides 1226 and the second air guides 1227 abut against each other. Specifically, the first air guides 1226 and the second air guides 1227 are provided on both the left and right sides of the motorcycle 100. These first and second air guides 1226 and 1227 can reduce air resistance, thereby increasing the speed of the motorcycle 100. The fuel tank 22 is at least partially recessed inward to form a storage space 10a. The electrical system 23 includes at least one electrical component, which is substantially located within the storage space 10a. This facilitates placement of the electrical component within the storage space 10a, thereby improving the integration of the fuel tank 22. More specifically, the at least one electrical component includes an onboard communicator 238 and a body controller 239. The storage space 10a includes a communication storage space 104 and a control storage space 105. The onboard communicator 238 is connected to the main frame 111 and is at least partially located within the communication storage space 104. The body controller 239 is connected to the main frame 111 and is at least partially located within the control storage space 105. Specifically, the onboard communicator 238 is used to provide a remote communication interface for the motorcycle 100, collect driving data, and record driving trajectory. The body controller 239 is used to control the power windows, air conditioning, and headlights. Through the above arrangement, the communication accommodation space 104 can protect the onboard communicator 238, and the control accommodation space 105 can protect the body controller 239, thereby improving the communication and control performance of the motorcycle 100, thereby further improving the intelligence level of the motorcycle 100 and also improving the service life of the electrical system 23. It should be noted that the fuel tank 22 is configured to be made of plastic and can be formed using a rotational molding process. The rotational molding process involves first adding plastic raw material in powder form into a mold, then continuously rotating the mold and heating the mold. At this time, the plastic raw material in the mold gradually and evenly melts and coats the entire surface of the mold cavity under the action of gravity and heat energy. The mold is then cooled, and the plastic product after demolding is a rotational molded product.

[0060] For example, a longitudinal plane 101 perpendicular to the width of the motorcycle 100 is defined. The projection of the body panel 12 onto the longitudinal plane 101 along the width of the motorcycle 100 is a first projection, and the projection of the second air guide 1227 onto the longitudinal plane 101 along the width of the motorcycle 100 is a second projection. The area ratio of the first projection to the second projection ranges from 0.4 to 1.6. Furthermore, the area ratio of the first projection to the second projection ranges from 0.6 to 1.2. Furthermore, the area ratio of the first projection to the second projection is 0.8. This arrangement prevents the second air guide 1227 from being too small due to an excessively large area ratio of the first projection to the second projection, thereby preventing increased wind resistance on the motorcycle 100 and increasing its speed. It also prevents the second air guide 1227 from being too large due to an excessively small area ratio of the first projection to the second projection, thereby preventing excessive exposure of the fuel tank 22 and causing damage, thereby increasing the service life of the fuel tank 22.

[0061] As one implementation, the fuel tank 22 includes an exposed portion 106, a first fuel tank 107, and a second fuel tank 108. The exposed portion 106 is generally located below the first and second fuel tanks 107, 108. The upper sides of the first and second fuel tanks 107, 108 are integrally formed and at least partially located above the main frame 111. The engine 151 is at least partially located between the first and second fuel tanks 107, 108. Specifically, the first fuel tank 107 is at least partially located on the left side of the main frame 111, and the second fuel tank 108 is at least partially located on the right side of the main frame 111. The exposed portion 106 is generally equivalent to the fuel tank guard 122. This arrangement allows the exposed portion 106, the first and second fuel tanks 107, 108 to protect the engine 151, thereby improving the safety of the engine 151.

[0062] Illustratively, the fuel tank 22 further includes a connecting oil pipe 1071 and a connecting valve 1081. A connecting valve 1081 is provided at the lower end of each of the first and second fuel tanks 107, 108. The ends of the connecting oil pipe 1071 are connected to the two connecting valves 1081, respectively, to establish communication between the first and second fuel tanks 107, 108. Specifically, the electrical system 23 further includes an oil level sensor 109, which is connected to the underside of the second fuel tank 108 and is capable of detecting the oil level in the fuel tank 22. This arrangement ensures that the oil levels in the first and second fuel tanks 107, 108 remain substantially the same, thereby preventing a shift in the center of gravity of the motorcycle 100 due to a significant difference in oil levels between the first and second fuel tanks 107, 108. This, in turn, improves the driving stability of the motorcycle 100. It should be noted that, when the motorcycle 100 is running normally, the communication valve 1081 is in an open state, and when the motorcycle 100 needs to be repaired, the communication valve 1081 is in a closed state.

[0063] As an implementation, the power system 15 further includes an oil pump 152 and an oil delivery pipe 153. The oil pump 152 is located below the first fuel tank 107 and is connected to the engine 151 via the oil delivery pipe 153. Specifically, the oil pump 152 can transfer the oil in the first and second fuel tanks 107, 108 to the engine 151 via the oil delivery pipe 153, thereby enabling the normal operation of the engine 151. Through the above arrangement, the oil pump 152 and the oil level sensor 109 are integrated into the lower side of the lower fuel tank 22, thereby improving the integration of the fuel tank 22. Furthermore, the oil pump 152 and the oil level sensor 109 are tightly connected to the fuel tank 22, thereby facilitating a more compact structure of the oil pump 152, the oil level sensor 109, and the fuel tank 22.

[0064] As shown in Figures 1, 11, and 12, as an implementation, the motorcycle 100 further includes a front shield assembly 27, which is at least partially connected to the frame 11. The frame 11 includes an integrated frame 118 located in front of the main frame 111, and the integrated frame 118 is connected to the main frame 111. The electrical system 23 includes a charging structure 233 and an instrument assembly 234. The front shield assembly 27 includes a front windshield 271, and the charging structure 233, the instrument assembly 234, and the front windshield 271 are all detachably connected to the integrated frame 118. Specifically, the charging structure 233, the instrument assembly 234, and the front windshield 271 are respectively located at different positions on the integrated frame 118, and the charging structure 233, the instrument assembly 234, and the front windshield 271 do not interfere with each other. Through the above arrangement, the charging structure 233, the instrument assembly 234 and the front windshield 271 can be removed from the integrated frame 118 separately, thereby improving the assembly performance of the charging structure 233, the instrument assembly 234, the front windshield 271 and the integrated frame 118. At the same time, when observed along the length direction of the motorcycle 100, the charging structure 233, the instrument assembly 234, the front windshield 271 and the integrated frame 118 at least partially overlap, so that the structure of the charging structure 233, the instrument assembly 234, the front windshield 271 and the integrated frame 118 is more compact, which is beneficial to improving the structural compactness of the charging structure 233, the instrument assembly 234, the front windshield 271 and the integrated frame 118.

[0065] As an implementation, a reference plane 102 perpendicular to the height direction of the motorcycle 100 is defined. The projection of the integrated frame 118 along the height direction of the motorcycle 100 on the reference plane 102 is set as a first projection plane. The projection of the charging structure 233, the instrument assembly 234, the front windshield 271, and the integrated frame 118 along the height direction of the motorcycle 100 on the reference plane 102 is set as a second projection plane. The ratio of the first projection plane to the second projection plane ranges from 0.7 to 0.9. Specifically, the ratio of the first projection plane to the second projection plane ranges from 0.75 to 0.85. More specifically, the ratio of the first projection plane to the second projection plane is set to 0.8. Through the above-mentioned arrangement, it is possible to avoid the volume of the integrated frame 118 being too large due to the ratio of the first projection surface to the second projection surface being too large, thereby preventing the integrated frame 118 from occupying a large space, which is beneficial to improving the space utilization rate of the motorcycle 100; it is also possible to avoid the volume of the charging structure 233, the instrument assembly 234 or the front windshield 271 being too large due to the ratio of the first projection surface to the second projection surface being too small, thereby preventing interference between the charging structure 233, the instrument assembly 234 and the front windshield 271, which is beneficial to improving the assembly performance of the motorcycle 100.

[0066] As an implementation, the vehicle frame 11 includes a front frame 119, which is located at the front side of the main frame 111 and fixedly connected to the main frame 111. The integrated frame 118 includes a bracket plate 1181, which is detachably connected to the front frame 119. The charging structure 233, the instrument assembly 234, and the front windshield 271 are all connected to the front frame 119 via the bracket plate 1181. Specifically, the front frame 119 is located below the bracket plate 1181. The front frame 119 and the bracket plate 1181 are fixedly connected by fasteners. The bracket plate 1181 serves as the main support frame of the integrated frame 118, and is used to support the charging structure 233, the instrument assembly 234, the front windshield 271, and other structures. When the charging structure 233, the instrument assembly 234, the front windshield 271, and other structures need to be installed or repaired, the bracket plate 1181 can be directly removed from the front frame 119. Through the above arrangement, the connection structure between the integrated frame 118 and the front frame 119 is simplified, which is conducive to improving the assembly performance of the front frame 119 and the integrated frame 118.

[0067] As an implementation, the integrated frame 118 further includes a windshield bracket 1182 detachably connected to the front side of the bracket plate 1181 and an adjustment shaft 1183 extending through the windshield bracket 1182. The windshield bracket 1182 and the adjustment shaft 1183 also extend through the bracket plate 1181, and the adjustment shaft 1183 is connected to the bracket plate 1181. The front windshield 271 is located in front of the windshield bracket 1182. The front windshield 271 is detachably connected to the windshield bracket 1182. The windshield bracket 1182 is movable on the adjustment shaft 1183, allowing the front windshield 271 to move along with the windshield bracket 1182. Specifically, the front windshield 271 is detachably connected to the bracket plate 1181 via the windshield bracket 1182. The adjustment shaft 1183 is rotatably connected to the windshield bracket 1182. The adjustment shaft 1183 is capable of controlling the windshield bracket 1182 to move in the vertical direction along the motorcycle 100, allowing the front windshield 271 to move up and down. Through the above-mentioned arrangement, the height of the front windshield 271 can be adjusted according to the needs of the rider. When the motorcycle 100 is traveling at high speed, the height of the front windshield 271 can be lowered to reduce air resistance, thereby facilitating an increase in the speed of the motorcycle 100. When the motorcycle 100 is traveling on rainy days, the height of the front windshield 271 can be raised so that the front windshield 271 can block part of the rain, thereby preventing the instrument assembly 234 from being damaged by the impact of rain, thereby facilitating an increase in the service life of the instrument assembly 234. It should be noted that the windshield bracket 1182 is provided with an adjustment slot 1182a for the adjustment shaft 1183 to pass through, and an adjustment rack 1182b is provided in the adjustment slot 1182a, which extends at least partially along the height direction of the motorcycle 100, and a gear 1183a is provided on the adjustment shaft 1183 to engage with the adjustment rack 1182b. The adjustment shaft 1183 and the windshield bracket 1182 are connected through the adjustment rack 1182b and the gear 1183a, so that the driver can adjust the front windshield 271 according to actual needs.

[0068] As an implementation, the integrated frame 118 also includes an instrument bracket 1184, which is located on the rear side of the support plate 1181 and is detachably connected to the support plate 1181. The instrument assembly 234 is located on the rear side of the instrument bracket 1184 and is connected to the instrument bracket 1184. Specifically, the instrument assembly 234 is detachably connected to the support plate 1181 via the instrument bracket 1184. When the instrument assembly 234 needs to be replaced, the instrument assembly 234 can be removed from the vehicle bracket, thereby improving the assembly of the instrument assembly 234. Furthermore, the instrument assembly 234 is rotatably connected to the instrument bracket 1184, allowing the driver to adjust the angle of the instrument assembly 234 as needed, thereby enhancing the adjustability of the instrument assembly 234. It will be appreciated that both the instrument bracket 1184 and the windshield bracket 1182 are connected to the front frame 119 via the support plate 1181.

[0069] As an implementation, the integrated frame 118 further includes a damping assembly 1185 . The damping assembly 1185 is located between the instrument bracket 1184 and the instrument assembly 234 . The instrument assembly 234 is rotatably connected to the instrument bracket 1184 via the damping assembly 1185 . Specifically, the damping assembly 1185 includes a damping mounting bracket 1185a, a damping member 1185b, a damping mounting cover 1185c and an instrument connecting plate 1185d. After the damping mounting cover 1185c and the damping mounting bracket 1185a are connected, a mounting groove 1185e is formed. The damping member 1185b is located in the mounting groove 1185e. The damping mounting bracket 1185a is connected to the instrument bracket 1184. The instrument connecting plate 1185d is connected to the damping mounting bracket 1185a through the damping member 1185b and the damping mounting cover 1185c, so that the instrument connecting plate 1185d can rotate relative to the instrument bracket 1184, wherein the instrument assembly 234 is fixedly connected to the instrument connecting plate 1185d, so that the instrument assembly 234 is connected to the instrument bracket 1184. Specifically, damping mounting bracket 1185a itself has a rotational function. One end of damping mounting bracket 1185a is connected to damping member 1185b and damping mounting cover 1185c, and the other end of damping mounting bracket 1185a is connected to instrument connecting plate 1185d. This allows instrument connecting plate 1185d to be rotatably connected to damping member 1185b and damping mounting cover 1185c via damping mounting bracket 1185a. Furthermore, instrument assembly 234 is fixedly connected to instrument connecting plate 1185d, thereby rotatably connecting instrument assembly 234 to instrument bracket 1184. This arrangement allows instrument assembly 234 to rotate forward or backward about the width of motorcycle 100, allowing the rider to adjust the instrument according to their needs, thereby improving the driving experience of motorcycle 100.

[0070] As an implementation, the vehicle body panel 12 further includes a fender 128 having a mounting hole 1283 defined therein. A charging structure 233 is at least partially located within the mounting hole 1283 and engages with the mounting hole 1283, thereby connecting the charging structure 233 to the fender 128. The fender 128 includes a left fender 1281 and a right fender 1282. The left fender 1281 is located on the left side of and connected to the integrated frame 118, while the right fender 1282 is located on the right side of and connected to the integrated frame 118. Both the left fender 1281 and the right fender 1282 are further connected to the windshield bracket 1182. Specifically, the charging structure 233 can provide power to external electrical appliances, thereby providing the motorcycle 100 with a charging function. Integrating the charging structure 233 into the front portion of the motorcycle 100 facilitates charging of external electrical appliances while the driver is driving, without affecting the operation of the rider and passengers. The above configuration improves the comprehensive functionality of the motorcycle 100, and the charging structure 233 and the integrated frame 118 are compact, thereby improving the compactness of the charging structure 233 and the integrated frame 118. It should be noted that the external electrical appliance can be a mobile phone or other electrical appliance.

[0071] As an implementation method, the vehicle body cover 12 also includes a lower guard plate 129, which is at least partially connected to the main frame 111. A through hole 1291 is provided on the lower guard plate 129, and the integrated frame 118 is at least partially penetrated by the through hole 1291. The protective plate 128 is engaged with the lower guard plate 129. Specifically, the front frame 119 is substantially located on the lower side of the lower guard plate 129, and the integrated frame 118 is substantially located on the upper side of the lower guard plate 129. The front frame 119 is at least partially penetrated by the through hole 1291 and is detachably connected to the integrated frame 118 by fasteners. Through the above arrangement, the lower guard plate 129 can protect the lower side of the integrated frame 118, preventing the use of the integrated frame 118 from being affected by particles such as mud and sand entering the integrated frame 118, thereby helping to increase the service life of the integrated frame 118.

[0072] As an implementation, the electrical system 23 further includes a signal transmitter 2345. The signal transmitter 2345 is located within the integrated frame 118 and is fixedly connected to the integrated frame 118. The signal transmitter 2345 is also electrically connected to the instrument assembly 234. Specifically, the signal transmitter 2345 can provide signals to the instrument assembly 234 so that the instrument assembly 234 displays accurate information, thereby facilitating accurate information acquisition for the rider and thereby improving the safety of the motorcycle 100. Through the above arrangement, the signal transmitter 2345 is disposed within the integrated frame 118, allowing the integrated frame 118 to protect the signal transmitter 2345. Furthermore, the signal transmitter 2345 can be disposed close to the instrument assembly 234, thereby reducing the length of the wiring harness between the signal transmitter 2345 and the instrument assembly 234, thereby improving the structural compactness of the motorcycle 100.

[0073] As shown in Figures 13 and 14 , as one implementation, the body panel 12 includes connecting guard plates 127 located on both sides of the main frame 111. The power system 15 includes an engine 151 connected to the frame 11. The electrical system 23 includes a rectifier and voltage regulator 239 electrically connected to the engine 151. The rectifier and voltage regulator 239 is used to receive the alternating current generated by the engine 151 and rectify and transmit it to the electrical equipment or battery of the motorcycle 100. The motorcycle 100 also includes a heat dissipation assembly 28, which includes a radiator 281. The radiator 281 is located in front of the engine 151. The body panel 12 includes a deflector housing 201 at least partially positioned forward of the connecting guard plate 127. The deflector housing 201 is fixedly connected to the main frame 111 and defines a heat dissipation cavity 2011 for air circulation. A rectifier / voltage regulator 239 is fixedly mounted on the deflector housing 201 and positioned within the heat dissipation cavity 2011. An air inlet 2012 is positioned forward of the deflector housing 201 for admitting air into the heat dissipation cavity 2011. When viewed along the length of the motorcycle 100, the air inlet 2012 at least partially overlaps with the rectifier / voltage regulator 239. In the prior art, the rectifier / voltage regulator 239 is typically located at the rear of the motorcycle 100 and utilizes vortexes generated by airflow from both sides of the motorcycle during travel to dissipate heat generated by the rectifier / voltage regulator 239. However, due to the relatively slow flow rate of the vortexes generated by the airflow from both sides, the heat dissipation effect of the rectifier / voltage regulator 239 is poor. In the embodiment of the present application, air can directly enter the air inlet 2012 and pass through the rectifier and voltage regulator 239 to remove the heat generated by the rectifier and voltage regulator 239. Through the above arrangement, the heat dissipation capacity of the rectifier and voltage regulator 239 is improved.

[0074] Specifically, when viewed from the height of the motorcycle 100, the rectifier and voltage regulator 239 is located in front of the radiator 281. Along the length of the motorcycle 100, the distance L1 between the rectifier and voltage regulator 239 and the radiator 281 ranges from 110 mm to 130 mm. Furthermore, the distance L1 between the rectifier and voltage regulator 239 and the radiator 281 ranges from 115 mm to 125 mm. More preferably, the distance L1 between the rectifier and voltage regulator 239 and the radiator 281 is 120 mm. If the distance between the rectifier and voltage regulator 239 and the radiator 281 is too large, the radiator 281 being located in front of the engine 151 will result in a greater distance between the rectifier and voltage regulator 239 and the engine 151. This, in turn, will result in a longer wiring harness 2391 connecting the rectifier and voltage regulator 239 and the engine 151, thereby increasing the production cost of the motorcycle 100. If the distance between the rectifier and voltage regulator 239 and the radiator 281 is too small, the radiator 281 has a high heat, which affects the heat dissipation capacity of the rectifier and voltage regulator 239. The above arrangement ensures the heat dissipation capacity of the rectifier and voltage regulator 239 while reducing the production cost of the motorcycle 100.

[0075] As an implementation method, an air outlet 2013 is provided on the guide shell 201 for the air in the heat dissipation cavity 2011 to flow out, and an air duct 2014 is formed in the heat dissipation cavity 2011, extending from the air inlet 2012 to the air outlet 2013. The rectifier and voltage regulator 239 is located in the air duct 2014, so that air can enter from the air inlet 2012 and flow through the rectifier and voltage regulator 239 before flowing out from the air outlet 2013, thereby improving the heat dissipation capacity of the rectifier and voltage regulator 239.

[0076] Because the outer surface of the flow guide housing 201 is uneven, a fixing surface 2015 for securing the rectifier and voltage regulator 239 is formed on one side of the flow guide housing 201 near the heat dissipation cavity 2011. The rectifier and voltage regulator 239 is secured to the fixing surface 2015 via fasteners. The fixing surface 2015 is flat. This arrangement improves the stability of the connection between the rectifier and voltage regulator 239 and the flow guide housing 201.

[0077] As an implementation, a wiring harness fixture 1115 is provided on the main frame 111. This fixture is used to secure the wiring harness 2391 connecting the rectifier and voltage regulator 239 to the engine 151. Due to the high temperature of the radiator 281, this arrangement prevents interference between the wiring harness 2391 and the radiator 281, potentially damaging the wiring harness 2391. This arrangement improves the safety of the wiring harness 2391.

[0078] As shown in FIG15 , as one implementation, the rectifier and voltage regulator 239 includes a wiring harness connector 2392 . The wiring terminals of the wiring harness connector 2392 are generally oriented toward the engine 151 and are angled downwardly toward the motorcycle 100. By positioning the wiring harness 2391 toward the engine 151, the length of the wiring harness 2391 connecting the rectifier and voltage regulator 239 to the engine 151 can be reduced, thereby reducing the production cost of the entire vehicle. Furthermore, the angled orientation of the wiring harness connector 2392 toward the motorcycle 100 prevents liquids such as rain or dew from flowing along the wiring harness 2391 into the wiring harness connector 2392, thereby improving the safety of the wiring harness connector 2392.

[0079] As shown in Figures 13 and 15, as an implementation method, the diversion housing 201 includes at least one housing fixing portion 2016, which is arranged at the lower end of the diversion housing 201. The housing fixing portion 2016 fixes the diversion housing 201 to the main frame 111 through fasteners, and the fasteners are exposed. A first clamping portion 2017 is provided on the side of the diversion housing 201 close to the connecting guard plate 127, and a second clamping portion 1271 is provided on the connecting guard plate 127 to be clamped with the first clamping portion 2017. The diversion housing 201 is detachably connected to the connecting guard plate 127 through the first clamping portion 2017. With the above arrangement, if the rectifier and voltage regulator 239 is damaged, the fasteners in the housing fixing portion 2016 can be removed, and then the first clamping portion 2017 and the second clamping portion 1271 can be separated to separate the flow guide housing 201 from the connecting guard plate 127, thereby allowing the rectifier and voltage regulator 239 to be removed from the flow guide housing 201. This reduces the difficulty of removing the rectifier and voltage regulator 239 and improves the convenience of maintaining the rectifier and voltage regulator 239. In addition, clamping the flow guide housing 201 to the connecting guard plate 127 can also reduce the number of fasteners required, thereby reducing the difficulty of connecting the flow guide housing 201 to the connecting guard plate 127.

[0080] As shown in FIG16 , as one implementation, the motorcycle 100 further includes an air filter assembly 29 coupled to the frame 11. The air filter assembly 29 includes an air filter 291, which is at least partially disposed on and fixedly connected to the subframe 114. The subframe 114 is provided with a first air filter securing portion 1145 extending along the width of the motorcycle 100. The first air filter securing portion 1145 is integrally formed with the subframe 114 and abuts against the air filter 291 along the width of the motorcycle 100 to secure the air filter 291.

[0081] It should be noted that in the prior art, air filter 291 is typically placed in subframe 114 after subframe 114 is assembled, and then first air filter fixing portion 1145 is fixedly connected to subframe 114 to secure air filter 291. In the embodiment of the present application, first air filter fixing portion 1145 is integrally formed with subframe 114. During the connection process between air filter 291 and subframe 114, air filter 291 is first placed between the two subframes 114, and then the two subframes 114 are fixedly connected to each other so that the first fixing portion abuts against air filter 291 to secure air filter 291. This eliminates the need to place air filter 291 in subframe 114 after the frame is installed. Compared to the prior art, the embodiment of the present application can increase the volume of air filter 291, thereby improving the air intake efficiency of air filter 291.

[0082] Specifically, the air filter 291 includes a first portion 2911 and a second portion 2912 arranged along the height of the motorcycle 100, with the second portion 2912 located below the first portion 2911. The upper main pipes 1141 extend along the length of the motorcycle 100 and are arranged in pairs. The front ends of the upper main pipes 1141, i.e., the portions of the upper main pipes 1141 that hold the air filter 291, are spaced apart along the width of the motorcycle 100 at a distance less than the maximum length of the second portion 2912 of the air filter 291 along the width of the motorcycle 100. Because the air filter 291 is typically assembled between the left and right subframes 114 after assembly, the second portion 2912 of the air filter 291 is relatively narrow along the width of the motorcycle 100. In the embodiment of the present application, by assembling the air filter 291 with the left and right sub-frames 114 at the same time, the width of the second portion 2912 along the width direction of the motorcycle 100 is made larger, thereby increasing the volume of the air filter 291 and thus improving the air intake efficiency of the air filter 291.

[0083] As an implementation method, the air filter 291 includes a second air filter fixing portion 2913, and the first air filter fixing portion 1145 is embedded in the second air filter fixing portion 2913 to fix the air filter 291. The air filter 291 also includes a buffer member 2914 located between the first air filter fixing portion 1145 and the second air filter fixing portion 2913, with both sides of the buffer member 2914 respectively abutting the first air filter fixing portion 1145 and the second air filter fixing portion 2913. The buffer member 2913 can be configured as an elastic member such as a rubber pad. Through the above configuration, while improving the fixing strength of the first air filter fixing portion 1145, it can also reduce the noise generated by the collision between the first air filter fixing portion 1145 and the second air filter fixing portion 2913, thereby improving the user experience of the driver and passengers.

[0084] As an implementation method, 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 along the height direction of the motorcycle 100 and is fixedly connected to the air filter 291 through fasteners, thereby limiting 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.

[0085] As shown in FIG17 , as one implementation, the air filter assembly 29 further includes an intake air temperature sensor 292, which is fixedly mounted on a first portion 2911 and extends through the first portion 2911 along the length of the motorcycle 100. Because the intake duct 2915 of the air filter 291 extends along the length of the motorcycle 100, extending the intake air temperature sensor 292 through the first portion 2911 along the length of the motorcycle 100 increases the contact area between the intake air temperature sensor 292 and the intake duct 2915, thereby improving the accuracy of the intake air temperature sensor 292's detection.

[0086] Furthermore, a receiving groove 2911a for accommodating the intake air temperature sensor 292 is formed on the first part 2911. Along 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) above the first part 2911, thereby improving the stability of the intake air temperature sensor 292.

[0087] Furthermore, a notch 2911b is formed in the receiving groove 2911a, facing the subframe 114. The notch 2911b allows the receiving groove 2911a to communicate with the outside world. When the motorcycle 100 is driven in the rain, rainwater can accumulate in the receiving groove 2911a, potentially damaging the intake air temperature sensor 292 therein. This arrangement allows rainwater to flow out of the notch 2911b, thereby improving the safety of the intake air temperature sensor 292.

[0088] Preferably, notch 2911b is located on the left side of longitudinal plane 101. Since the temple of motorcycle 100 is generally located on the left side of motorcycle 100, the motorcycle 100 tilts to the left when parked. This arrangement prevents rainwater from accumulating in receiving groove 2911a when motorcycle 100 is parked, potentially damaging intake air temperature sensor 292 and thereby extending the service life of intake air temperature sensor 292.

[0089] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all such improvements and changes should fall within the scope of protection of the appended claims of the present invention.

[0090] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application. Therefore, the scope of patent protection for the present application shall be determined by the appended claims.
