Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to a motorcycle. Background Technology

[0002] One end of the engine's secondary air injection valve is connected to the engine via a pipe, and the other end is connected to the air filter via another pipe. The secondary air injection valve introduces fresh air into the engine's exhaust gas, increasing the oxygen content and allowing unburned hydrocarbons and carbon monoxide in the high-temperature exhaust to be re-burned and oxidized, thereby reducing engine fuel consumption and exhaust pollutants. In existing technology, the secondary air injection valve is located far from the engine, requiring a long piping system, resulting in poor space utilization. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, the purpose of this application is to provide a motorcycle with a high space utilization rate for its secondary air replenishment valve.

[0004] To achieve the above objectives, this application adopts the following technical solution:

[0005] A motorcycle includes a frame, a body panel, a running gear assembly, and a power assembly. The body panel is at least partially fixedly connected to the frame. The running gear assembly is at least partially located below the frame. The power assembly is supported by the frame and is drively connected to the running gear assembly. The power assembly includes an engine, an air filter, and a secondary air injection valve. The secondary air injection valve is located between the air filter and the engine and is fixedly connected to the air filter. Viewed along the width of the motorcycle, the secondary air injection valve at least partially overlaps with the frame. The power assembly also includes a mounting sheet metal. The secondary air injection valve is fixedly connected to the mounting sheet metal. The air filter has mounting holes for the sheet metal. The mounting sheet metal is located below the air filter and is fixedly connected to the air filter through the mounting holes.

[0006] Furthermore, the sheet metal installation includes a first sheet metal and a second sheet metal. The first sheet metal is fixedly connected to the air filter through sheet metal mounting holes, and the second sheet metal is fixedly connected to the secondary air injection valve.

[0007] Furthermore, the first sheet metal extends along the width direction of the motorcycle, and the second sheet metal extends along the height direction of the motorcycle. When viewed along the width direction of the motorcycle, the second sheet metal at least partially overlaps with the secondary air injection valve.

[0008] Furthermore, a fixing post is provided on the second sheet metal, and a mounting part is provided on the secondary air supply valve, with the fixing post passing through the mounting part.

[0009] Furthermore, the second sheet metal is also provided with a hollow section, through which at least part of the secondary air supply valve passes.

[0010] Furthermore, two sheet metal mounting holes are arranged side by side, and two fixing posts are arranged side by side.

[0011] Furthermore, the body panels include a windshield located above and fixedly connected to the engine, and a secondary air intake valve located between the windshield and the air filter.

[0012] Furthermore, the windshield is recessed towards the engine side to form a groove, and the secondary air supply valve is at least partially located within the groove.

[0013] Furthermore, the power assembly includes an intake pipe, one end of which is connected to the engine via the secondary air supply valve, and the other end of which is connected to the air filter; the intake pipe is at least partially penetrated by a windshield.

[0014] Furthermore, a sealing ring is provided between the air intake pipe and the windshield, and a wire hole is provided on the windshield. The wire hole is located in the groove, and the sealing ring is engaged with the wire hole. The air intake pipe passes through the wire hole.

[0015] The motorcycle described above places the secondary air replenishment valve between the engine and the air filter, and fixes it to the air filter. This makes the secondary air replenishment valve closer to the engine and the air filter, thereby reducing the required pipeline length, facilitating pipeline layout, and improving the space utilization of the secondary air replenishment valve.

[0035] To enable those skilled in the art to better understand the solutions of this application, the technical solutions in specific embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0036] like Figure 1As shown, a motorcycle 100 includes a frame 11, a body panel 12, a running gear 13, a power assembly 14, and a suspension assembly 15. The frame 11 forms the basic framework of the motorcycle 100, primarily providing support for other components. The body panel 12 is at least partially connected to the frame 11, protecting the internal parts of the motorcycle 100. The running gear 13 is at least partially disposed below the frame 11 and connected to it via the suspension assembly 15. The running gear 13 includes a front wheel 131 and a rear wheel 132. The power assembly 14 is at least partially connected to the frame 11 and is driveably connected to the running gear 13. The power assembly 14 generates driving force to propel the motorcycle 100. To clearly illustrate the technical solution of this application, the following are also defined: Figure 1 The front, rear, left, right, top, and bottom sides are shown. It is understood that in this embodiment, the length direction refers to the front-to-back direction of the motorcycle 100, the width direction refers to the left-to-right direction of the motorcycle 100, and the height direction refers to the up-down direction of the motorcycle 100.

[0037] like Figure 2 As shown, the frame 11 includes a main frame 111, and the power assembly 14 includes an engine 141, which is fixedly connected to the main frame 111 (see reference). Figure 7 The motorcycle 100 also includes a cooling assembly 16, which includes a radiator 161. The body panel 12 includes a windshield 121. The radiator 161 is located in front of the engine 141 and is fixedly connected to the main frame 111 (see reference). Figure 7The windshield 121 is at least partially located above the radiator 161 and the engine 141, and is fixedly connected to the radiator 161 and the engine 141. The windshield 121 is also at least partially located behind the radiator 161. When the radiator 161 is working, the cooling fan on the radiator 161 blows hot air backward. During the backward blowing process, the hot air is blocked by the engine 141 and splits into multiple directions. Some of the hot air blows upward and blows onto the driver through the gaps inside the motorcycle 100, resulting in a higher perceived temperature for the driver and a poor driving experience. In order to avoid the hot air blowing onto the driver and affecting the driver's driving experience, the windshield 121 is set above the engine 141 to prevent the hot air from blowing upward and blowing onto the driver through the gaps inside the motorcycle 100, thereby reducing the perceived temperature for the driver and improving the driver's driving experience. Specifically, the windshield 121 includes a snap-fit ​​hole 1211, which is snapped onto the radiator 161 and the engine 141. Since the engine 141 will vibrate significantly during operation, in order to prevent the connection between the windshield 121 and the engine 141 from falling off due to vibration, the snap-fit ​​hole 1211 includes a first snap-fit ​​hole 1211a, a second snap-fit ​​hole 1211b, and a third snap-fit ​​hole 1211c. A front snap-fit ​​portion 1611 is formed on the top of the radiator 161, side snap-fit ​​portions 1414 are formed on the left and right sides of the engine 141, and an upper snap-fit ​​portion 1415 is formed on the top of the engine 141. The first snap-fit ​​hole 1211a snaps onto the front snap-fit ​​portion 1611, the second snap-fit ​​hole 1211b snaps onto the side snap-fit ​​portion 1414, and the third snap-fit ​​hole 1211c snaps onto the upper snap-fit ​​portion 1415. Specifically, the first latching hole 1211a is located in front of the second latching hole 1211b, and the third latching hole 1211c is basically located between the first latching hole 1211a and the second latching hole 1211b. Viewed along the height direction of the motorcycle 100, the third latching hole 1211c is basically located on both sides of the engine 141, and viewed along the width direction of the motorcycle 100, the third latching hole 1211c is located below the first latching hole 1211a and the second latching hole 1211b. Furthermore, there are two of each of the first latching hole 1211a, the second latching hole 1211b, and the third latching hole 1211c, and all three are distributed along the width direction of the motorcycle 100. With the above configuration, the snap-fit ​​hole 1211 can facilitate the fixed connection of the windshield 121 to the radiator 161 and the engine 141, and the multiple snap-fit ​​holes 1211 can also improve the connection stability of the windshield 121.

[0038] like Figure 3 and Figure 4 As shown, the motorcycle 100 also includes an electrical component 17 (see reference). Figure 2The electrical assembly 17 includes a wiring harness 171, which is used to connect a power source and an electrical appliance, or to connect an electrical appliance and a controller 175. In this application, the wiring harness 171 is used to connect an ignition coil and an ignition switch. The ignition switch controls the ignition coil to generate an electric spark to make the engine 141 work. The ignition coil is located on the engine 141. Therefore, the wiring harness 171 is at least partially located above the engine 141 and extends along the width direction of the motorcycle 100. A fixing bolt 1411 is also provided above the engine 141. The fixing bolt 1411 is used to connect various components of the engine 141. For example, the fixing bolt 1411 is used to connect the cylinder head and cylinder head cover of the engine 141. The wiring harness 171 in this application will pass through the fixing bolt 14111 during the arrangement process. Since the edge of the fixing bolt 1411 is relatively sharp, the fixing bolt 1411 may rub against the wiring harness 171 during the operation of the motorcycle 100, causing damage to the wiring harness 171. Specifically, the rear end of the windshield 121 is provided with a protective part 1212, which covers the fixing bolt 1411. Viewed along the length of the motorcycle 100, the protective part 1212 and the fixing bolt 1411 at least partially overlap, thereby preventing direct contact between the connecting harness 171 and the fixing bolt 1411, avoiding damage due to friction, and improving the service life of the motorcycle 100. Furthermore, the windshield 121 is made of a high-temperature resistant and wear-resistant material. In this application, the windshield 121 is made of TPU (Thermoplastic Urethane), which, while isolating the heat from the engine 141, also effectively protects the connecting harness 171, preventing damage caused by high-frequency vibrations generated during engine operation.

[0039] like Figure 5 and Figure 6In this embodiment, the motorcycle 100 further includes a fuel assembly 18, which includes a fuel tank 181. The fuel tank 181 is at least partially located above the engine 141 and radiator 161 and is fixedly connected to the frame 11. The fuel tank 181 is also located above the windshield 121. The fuel tank 181 is connected to the engine 141 via a pipeline. The fuel tank 181 is mainly used to store fuel and supply fuel to the engine 141 through the pipeline. The motorcycle 100 also includes a steering assembly 19, which is rotatably connected to the frame 11. The steering assembly 19 is used to control the direction of travel of the motorcycle 100. The fuel tank 181 is also at least partially located behind the steering assembly 19. A fuel tank cap 1811 is provided on the upper side of the fuel tank 181. The power assembly 14 also includes a front exhaust pipe 142 located at least partially in front of the engine 141. At least part of the front exhaust pipe 142 extends along the height direction of the motorcycle 100. The upper end of the front exhaust pipe 142 is connected to the engine 141 to exhaust the exhaust gas generated by the engine 141 during operation. There is a gap between the fuel tank 181 and the steering assembly 19. Without the windshield 121, if fuel accidentally spills from the fuel tank cap 1811 and onto the fuel tank 181 during refueling, the fuel will pass through the fuel tank 181 and the engine 141 under the influence of gravity. Fuel drips from the gap between the steering components 19 and the engine 141 and radiator 161 onto the front exhaust pipe 142. The front exhaust pipe 142 is hot, and fuel, being flammable, is easily ignited by the high temperature of the exhaust pipe 142, posing a safety hazard to the motorcycle 100. Therefore, in this application, the fuel tank 181 is located above the windshield 121, which in turn is located above the engine 141 and radiator 161. This effectively blocks the gap between the radiator 161 and the engine 141, preventing fuel drips from contacting the hot engine 141 or the front exhaust pipe 142 and causing a hazard. Specifically, the windshield 121 is provided with guide portions 1213, located on both sides of the windshield 121 along the width direction of the motorcycle 100. The guide portions 1213 are designed as flanged structures protruding outwards from the edge of the windshield 121, thereby constraining the fuel path and guiding the fuel to the correct position to avoid hazard. The phrase "windshield 121 protrudes outward" as mentioned above refers to the edge of the windshield 121 protruding away from the engine 141. (See reference...) Figure 5 and Figure 6The fuel flow path indicated by the middle arrow, viewed along the height of the motorcycle 100, shows that the gap between the fuel tank 181 and the steering assembly 19 at least partially overlaps with the guide section 1213. That is, the guide section 1213 can be observed through the gap between the fuel tank 181 and the steering assembly 19. It can be understood that when fuel flows out from the fuel tank cap 1811, it slides forward along the surface of the fuel tank 181 and drips through the gap between the fuel tank 181 and the steering assembly 19 onto the windshield 121. Under the guidance of the guide section 1213, it slides to both sides of the windshield 121 and finally drips onto the ground below the motorcycle 100. Through this arrangement, the guide section 1213 constrains the fuel path, ensuring that the fuel drips along a pre-planned path, thereby avoiding safety hazards and improving the safety of the motorcycle 100.

[0040] Furthermore, such as Figure 6 As shown, viewed along the height of the motorcycle 100, the windshield 121 at least partially overlaps with the front exhaust pipe 142. The maximum distance of the guide portion 1213 along the width direction of the motorcycle 100 is defined as the guide width H1, and the maximum distance of the front exhaust pipe 142 along the width direction of the motorcycle 100 is defined as the exhaust width H2. The guide width H1 is greater than or equal to the exhaust width H2. Therefore, after fuel flows through the guide portion 1213, it will not drip onto the hot front exhaust pipe 142, but rather drip from the outside of the front exhaust pipe 142 onto the ground. With this arrangement, the guide width H1 being greater than the exhaust width H2 allows the windshield 121 to cover the front exhaust pipe 142. When fuel drips through the guide portion 1213, it will not drip onto the hot front exhaust pipe 142, thus avoiding maintenance and improving the safety of the motorcycle 100.

[0041] like Figure 3 and Figure 7As shown, in this embodiment, the power assembly 14 also includes an air filter 143, which is located above the engine 141 and connected to the engine 141 via a pipeline. The air filter 143 is mainly used to filter dust in the air, making the air entering the engine 141 cleaner and protecting the engine 141 from wear and damage. The power assembly 14 also includes a secondary air supply valve 144, one end of which is connected to the engine 141 via a pipeline, and the other end of which is connected to the air filter 143 via a pipeline. The secondary air supply valve 144 can add fresh air to the exhaust gas discharged from the engine 141 to increase the oxygen content in the exhaust gas, allowing unburned hydrocarbons and carbon monoxide in the high-temperature exhaust gas to be re-burned and oxidized, thereby reducing the fuel consumption of the engine 141 and reducing exhaust pollutants. The engine 141 also includes a cylinder head 1412, which is located behind the radiator 161. The cylinder head 1412 is engaged with the windshield 121. Along the height direction of the motorcycle 100, the secondary air supply valve 144 is located between the cylinder head 1412 and the air filter 143. The secondary air supply valve 144 is also located above the windshield 121. When viewed along the width direction of the motorcycle 100, the secondary air supply valve 144 also overlaps at least partially with the main frame 111. That is, when viewed along the width direction of the motorcycle 100, the main frame 111 can shield at least part of the secondary air supply valve 144, thereby enabling the frame 11 to provide protection for the secondary air supply valve 144. The windshield 121 also has a groove 1214, and the secondary air supply valve 144 is at least partially located within the groove 1214. This allows the secondary air supply valve 144 to be closer to the engine 141, reducing the length of the pipeline between the secondary air supply valve 144 and the engine 141 and improving the space utilization of the motorcycle 100. In addition, the heat insulation effect of the windshield 121 can also reduce the operating temperature of the secondary air supply valve 144.

[0042] like Figure 3 As shown, the power assembly 114 further includes an intake pipe 145 and an exhaust pipe 146 (see reference). Figure 8The intake pipe 145 connects the engine 141 and the secondary air replenishment valve 144. The intake pipe 145 is used to guide the exhaust gas discharged from the engine 141 into the secondary air replenishment valve 144. The exhaust pipe 146 connects the air filter 143 and the secondary air replenishment valve 144. The exhaust pipe 146 is used to guide the exhaust gas in the secondary air replenishment valve 144 into the air filter 143, so that the exhaust gas mixes with fresh air after passing through the air filter 143 and is reintroduced into the engine 141 to participate in the operation of the engine 141. This makes the combustion of the gas in the engine 141 more complete, reduces the fuel consumption of the engine 141, and also reduces the content of pollutants in the exhaust emissions. More specifically, a wire hole 1214a is provided in the groove 1214. The wire hole 1214a is located at the bottom of the groove 1214. The intake pipe 145 passes through the wire hole 1214a and is connected to the engine 141. The connection between the intake pipe 145 and the engine 141 through the wire hole 1214a can avoid the intake pipe 145 from going around, thereby reducing the length of the intake pipe 145 and facilitating the arrangement of the intake pipe 145. In addition, a sealing ring 1214b is provided on the wire hole 1214a. The sealing ring 1214b is engaged with the wire hole 1214a. The sealing ring 1214b is made of high-temperature resistant rubber material. The intake pipe 145 is connected to the engine 141 after passing through the sealing ring 1214b. The inner diameter of the sealing ring 1214b is slightly smaller than the outer diameter of the intake pipe 145. This allows the sealing ring 1214b to seal the wire hole 1214a through its own deformation when the intake pipe 145 passes through the sealing ring 1214b and the wire hole 1214a. This prevents the hot air discharged from the radiator 161 from blowing upward through the wire hole 1214a, and also prevents accidentally spilled fuel from dripping downward through the wire hole 1214a onto the engine 141 or the front exhaust pipe 142, which could cause danger.

[0043] like Figure 8 and Figure 9As shown, specifically, the secondary air injection valve 144 is fixedly connected to the air filter 143. The power assembly 14 also includes a mounting sheet metal 147, which is located below and fixedly connected to the air filter 143. The secondary air injection valve 144 is fixedly connected to the mounting sheet metal 147. The mounting sheet metal 147 is formed into an "L" shape by bending and is divided into a first sheet metal 1471 and a second sheet metal 1472 at the bend. The first sheet metal 1471 extends along the width direction of the motorcycle 100 and is used to mount the second sheet metal 1472. The first sheet metal 1471 is fixedly connected to the air filter 143. The second sheet metal 1472 extends along the height of the motorcycle 100 and is used to fix the mounting sheet metal 147 to the secondary air supply valve 144. A sheet metal mounting hole 1431 is also provided below the air filter 143. The first sheet metal 1471 is fixedly connected to the sheet metal mounting hole 1431, thereby achieving the connection between the mounting sheet metal 147 and the air filter 143. Two sheet metal mounting holes 1431 are arranged side-by-side, which improves the connection stability between the first sheet metal 1471 and the air filter 143. Furthermore, a fixing post 1472a is provided on the second sheet metal 1472, and a mounting part 1441 is provided on the secondary air supply valve 144. The fixing post 1472a at least partially passes through the mounting part 1441 and is fixedly connected to the mounting part 1441, thereby fixing the mounting sheet metal 147 to the secondary air supply valve 144. Understandably, the number of fixing posts 1472a is also two arranged side by side to improve the connection stability between the secondary air supply valve 144 and the second sheet metal 1472, and to prevent the secondary air supply valve 144 from falling off the second sheet metal 1472. With the above arrangement, since the air filter 143 is located close to the engine 141, and the secondary air supply valve 144 is fixed below the air filter 143, the distance between the secondary air supply valve 144 and the engine 141 and the air filter 143 is very close, thereby reducing the length of the pipeline between the secondary air supply valve 144 and the engine 141 and the air filter 143. In addition, it can make full use of the area above the windshield 121. The arrangement of the secondary air supply valve 144 can also make the structure of the various components of the motorcycle 100 more compact, improving the space utilization of the motorcycle 100.

[0044] In this embodiment, the second sheet metal 1472 is provided with a hollow portion 1472b, and the secondary air replenishment valve 144 passes through at least part of the hollow portion 1472b along the width direction of the motorcycle 100. This hollow portion 1472b allows the distance between the fixing post 1472a and the mounting portion 1441 to be closer, thereby making the connection between the fixing post 1472a and the secondary air replenishment valve 144 more stable and preventing the secondary air replenishment valve 144 from detaching from the second sheet metal 1472 due to vibration during motorcycle operation. Furthermore, the mounting sheet metal 147 is made of metal, and when viewed along the width direction of the motorcycle 100, the mounting sheet metal 147 at least partially overlaps with the secondary air replenishment valve 144. This allows the secondary air replenishment valve 144 to be fixedly connected to the air filter 143 via the mounting sheet metal 147, while also providing protection for the secondary air replenishment valve 144.

[0045] like Figure 10 and Figure 11As shown, the electrical assembly 17 also includes a rectifier 172 and a battery 173. The battery 173 is mainly used to provide power to the various electrical appliances of the motorcycle 100. The rectifier 172 is mainly used to convert AC power into DC power and supply it to the load or inverter after filtering, while also providing charging voltage to the battery 173. In this application, the frame 11 also includes an electrical bracket 112, which is at least partially located behind the engine 141 and fixedly connected to the main frame 111. The motorcycle 100 also includes a seat assembly 21, and the electrical bracket 112 is at least partially located below the seat assembly 21. The rectifier 172 is located on the electrical bracket 112, and the rectifier 172 is provided with a rectifier fixing hole 1721, which is fixedly connected to the electrical bracket 112. The engine 141 also includes a cylinder head 1412 and a crankcase 1413, which are distributed along the height direction of the motorcycle 100. Since the engine 141 of this application is a four-cylinder engine, a receiving space 102 is formed around the rear of the cylinder head 1412 and the upper part of the crankcase 1413. The electrical bracket 112 is at least partially located in the receiving space 102, thereby making the layout of the electrical components 17 more compact and improving the space utilization of the motorcycle 100. Specifically, a fixing part 1111 is provided on the main frame 111, and the electrical bracket 112 includes a bracket mounting part 1121. The bracket mounting part 1121 is located at the front end of the electrical bracket 112, and the bracket mounting part 1121 is detachably connected to the fixing part 1111. There are two bracket mounting parts 1121, and the two bracket mounting parts 1121 are distributed along the width direction of the motorcycle 100. The frame 11 also includes a battery bracket 113 for connecting the battery 173. The battery 173 is at least partially located behind the rectifier 172 and fixedly connected to the battery bracket 113. The battery bracket 113 is located behind the electrical bracket 112 and fixedly connected to the frame 11. The battery bracket 113 is also fixedly connected to the electrical bracket 112, thereby enabling the electrical bracket 112 and the battery bracket 113 to be connected as a whole, allowing the electrical bracket 112 and the battery bracket 113 to support each other and improve the connection stability of the electrical bracket 112 and the battery bracket 113. In addition, the battery bracket 113 is at least partially located above the rear wheel 132. When the motorcycle 100 is in motion, the rear wheel 132 may carry mud and sand during rotation, causing mud and sand to splash. The battery bracket 113 can also prevent mud and sand from splashing and protect the electrical components 17. Furthermore, the electrical bracket 112 is made of plastic, which can reduce weight and prevent the heat radiation temperature of the engine 141, thereby ensuring that the temperature of the rectifier 172 is within the normal operating temperature range, and thus improving the working stability of the rectifier 172.

[0046] like Figure 11 and Figure 12As shown, the electrical assembly 17 also includes an anti-lock braking system (ABS) 174 and a body control module (BCM) 175. The ABS 174 is electrically connected to the body control module and wheel speed sensors located on the front wheel 131 and rear wheel 132. The ABS 174 is mainly used to prevent the tires from locking up during braking, maintaining the stability and safety of the vehicle. The body control module 175 is mainly used to monitor and manage body-related functions to allow the driver to better control the vehicle. These components are typically scattered throughout the motorcycle 100, requiring the removal of multiple parts during maintenance, resulting in poor maintainability of the motorcycle 100. In this application, both the anti-lock braking system (ABS) 174 and the controller 175 are mounted on the electrical bracket 112. The ABS 174 is at least partially located in front of the rectifier 172. The electrical bracket 112 has a receiving groove 1127, and the rectifier 172 is at least partially located within the receiving groove 1127. Viewed along the width of the motorcycle 100, the controller 175 is at least partially located above the rectifier 172. The fuel assembly 18 also includes a carbon canister 182, which is connected to the fuel tank 181 via a pipeline. The carbon canister 182 is mainly used to recover the fuel vapor evaporated from the fuel tank 181, preventing it from being released into the air and causing pollution, and to send the recovered fuel vapor back to the engine 141 for combustion, achieving energy-saving effects. The carbon canister 182 is also mounted on the electrical bracket 112 and located in front of the rectifier 172. Viewed along the width of the motorcycle 100, the carbon canister 182 at least partially overlaps with the ABS 174. Specifically, the electrical bracket 112 is provided with an anti-lock braking system (ABS) fixing part 1122, a controller fixing part 1123, and a carbon canister fixing part 1124. The ABS fixing part 1122 is fixedly connected to the anti-lock braking mechanism 174. The carbon canister 182 and the controller 175 are both connected to the carbon canister fixing part 1124 and the controller fixing part 1123 by plugging in, so as to prevent the carbon canister 182 or the controller 175 from falling off due to vibration during the operation of the motorcycle 100. Furthermore, the ABS fixing part 1122 and the carbon canister fixing part 1124 are located in front of the controller fixing part 1123, and when viewed along the width direction of the motorcycle 100, the ABS fixing part 1122 and the carbon canister fixing part 1124 at least partially overlap. Through the above configuration, the electrical bracket 112 also integrates multiple electrical components 17 and fuel components 18, thereby facilitating the maintenance of the electrical components 17 and fuel components 18. The integrated configuration also makes the layout between the various components more compact, improving the space utilization of the motorcycle 100. In addition, the integrated installation of multiple electrical components 17 and fuel components 18 can effectively reduce the connection lines between various components, thereby facilitating wiring layout and making the overall vehicle wiring neater and clearer.

[0047] like Figure 12 and Figure 13 As shown, the electrical assembly 17 also includes a solenoid valve 176, which is mainly used to control the opening and closing of the carbon canister 182. A connecting harness 171 is distributed along the width of the motorcycle 100 and connects to the spark plug on the cylinder head 1412 of the engine 141, thereby enabling the ignition function of the engine 141. The front end of the electrical bracket 112 is also provided with a wiring groove 1125 and a solenoid valve fixing part 1126. The wiring groove 1125 and the solenoid valve fixing part 1126 are located between two bracket mounting parts 1121. The solenoid valve 176 is connected to the solenoid valve fixing part 1126 by a plug-in connection to prevent the solenoid valve 176 from falling off. The wiring groove 1125 extends along the width of the motorcycle 100. The solenoid valve 176 is at least partially located above the wiring groove 1125 and is fixedly connected to the electrical bracket 112. The connecting harness 171 is at least partially located within the wiring groove 1125. With the above settings, the cable tray 1125 can provide space for the arrangement of the connecting wire harness 171, thereby optimizing the layout of the connecting wire harness 171. In addition, the cable tray 1125 can also ensure that the routing of the connecting wire harness 171 is not affected by the solenoid valve 176.

[0048] like Figure 14 and Figure 15As shown, the frame 11 includes a head tube 114, and the steering assembly 19 includes a steering handlebar 191, which is rotatably connected to the head tube 114. The driver controls the steering handlebar 191 to achieve the vehicle's turning function. The suspension assembly 15 includes an upper link plate 151, and the steering handlebar 191 is rotatably connected to the head tube 114 through the upper link plate 151. The steering assembly 19 also includes a steering damper 192. During high-speed travel of the motorcycle 100, the steering handlebar 191 may deflect, causing the motorcycle 100 to sway left and right, thus posing a safety hazard and potentially threatening the driver's life. Therefore, a steering damper 192 is required. The steering damper 192 provides resistance to limit the rotation of the steering handlebar 191 when it is rotated rapidly and significantly, thereby preventing the steering handlebar 191 from deflecting when the motorcycle 100 is moving at high speed. Specifically, the steering damper 192 includes a damping cylinder 1921 and a damping rod 1922. The damping rod 1922 is at least partially located inside the damping cylinder 1921. The steering assembly 19 also includes a mounting post 193. The damping rod 1922 is fixedly connected to the upper connecting plate 151 via the mounting post 193. The damping cylinder 1921 is fixedly connected to the frame 11. As the steering handlebar 191 rotates, the damping rod 1922 can move within the damping cylinder 1921. Since there is resistance when the damping rod 1922 moves within the damping cylinder 1921, when the steering handlebar 191 deflects, the resistance inside the steering damper 192 counteracts the deflection force of the steering handlebar 191, making it necessary to exert more force to rotate the steering handlebar 191. This prevents the steering handlebar 191 from deflecting, thereby avoiding lateral swaying of the vehicle at high speeds and improving the driving safety of the motorcycle 100.

[0049] In one implementation, the steering assembly 19 also includes a damper bracket 194, which includes a mounting bracket 1941 and an adjusting bracket 1942. The adjusting bracket 1942 and the mounting bracket 1941 are rotatably connected. The damping cylinder 1921 passes through the adjusting bracket 1942 and is fixedly connected to it. The mounting bracket 1941 is fixedly connected to the frame 11. The frame 11 also includes a fixing bracket 115 (see reference). Figure 14The fixed bracket 115 is located behind the head tube 114 and is fixedly connected to the main frame 111 by welding. The mounting bracket 1941 is also fixedly connected to the fixed bracket 115. The mounting bracket 1941 includes a rotating hole 1941a, and the adjusting bracket 1942 includes a rotating end 1942a. The rotating end 1942a is located behind the damping cylinder 1921 and is rotatably connected to the rotating hole 1941a, so that the adjusting bracket 1942 is rotatably connected to the mounting bracket 1941. It can be understood that a spherical bearing is provided in the rotating end 1942a, and the fastener passes through the spherical bearing and is connected to the rotating hole 1941a. Thus, while the adjusting bracket 1942 is fixedly connected to the mounting bracket 1941, the steering damper 192 can also rotate with the rotation of the steering handle 191 to avoid affecting the normal driving of the motorcycle 100. The adjustment bracket 1942 also includes a first adjustment portion 1942b and a second adjustment portion 1942c distributed along the height direction of the motorcycle 100. Both the first adjustment portion 1942b and the second adjustment portion 1942c are located in front of the rotating end 1942a. An installation space is formed between the first adjustment portion 1942b and the second adjustment portion 1942c for the damping cylinder 1921 to pass through. The adjustment bracket 1942 also includes an adjustment bolt 1942d. Along the height direction of the motorcycle 100, the adjustment bolt 1942d passes through the first adjustment portion 1942b and the second adjustment portion 1942c. It is understood that the adjustment bolt 1942d has both a loosened state and a tightened state. When the adjusting bolt 1942d is tightened, the first adjusting part 1942b and the second adjusting part 1942c can apply pressure to the damping cylinder 1921 to achieve a fixed connection between the adjusting bracket 1942 and the damping cylinder 1921; when the adjusting bolt 1942d is loosened, the pressure applied to the damping cylinder 1921 by the first adjusting part 1942b and the second adjusting part 1942c is reduced or disappears, and the damping cylinder 1921 can move relative to the first adjusting part 1942b and the second adjusting part 1942c along the width direction of the motorcycle 100, so that the position of the damping cylinder 1921 can be adjusted by moving the damping cylinder 1921. With the above settings, since the upper connecting plate 151 is different for different vehicle models, the distance between the upper connecting plate 151 and the head tube 114 is also different. Therefore, different steering dampers 192 are required for adaptation. The setting of the adjustment bracket 1942 in this application enables the steering damper 192 to be adapted to different vehicle models by adjusting the position of the damping cylinder 1921, thereby improving the platformization and versatility of the steering damper 192.

[0050] like Figure 16As shown, in this embodiment, the mounting bracket 1941 further includes a bracket fixing hole 1941b. The axial directions of both the bracket fixing hole 1941b and the rotating hole 1941a are parallel to the axial direction of the head tube 114. Viewed along the height direction of the motorcycle 100, the rotating hole 1941a is at least partially located in front of the bracket fixing hole 1941b. Two bracket fixing holes 1941b are provided, and the two bracket fixing holes 1941b are distributed along the width direction of the motorcycle 100. Understandably, the axis of rotation between the mounting bracket 1941 and the fixed bracket 114 is the rotation center of the steering damper 192. Since multiple functional components need to be integrated at the front of the motorcycle 100, the space for the front of the motorcycle 100 is relatively tight. In this application, the axis of rotation between the mounting bracket 1941 and the fixed bracket 114 and the axis of the damping cylinder 1921 are not in the same area, so that the rotation center of the steering damper 192 can be set off eccentrically. This allows the position of the bracket fixing hole 1941b to avoid the area of ​​the front tube 114 where many components are set, which is beneficial to the installation of the steering damper 192 and improves the assembly performance of the motorcycle 100.

[0051] Define a reference plane 102 perpendicular to the axis of the head tube 114. Along the axis of the head tube 114, the distance H3 between the projection of the rotation axis between the mounting bracket 1941 and the fixed bracket 114 on the reference plane 102 and the projection of the damping cylinder 1921 on the reference plane 102 is 20mm to 28mm. In this embodiment, the axis of rotation between the mounting bracket 1941 and the fixed bracket 114 refers to the axis of the rotating hole 1941a. That is, the distance H3 between the projection of the axis of the damping cylinder 1921 on the reference plane 102 and the projection of the axis of the rotating hole 1941a on the reference plane 102 is 20mm to 28mm. More specifically, the distance H3 between the projection of the axis of the damping cylinder 1921 on the reference plane 102 and the projection of the axis of the rotating hole 1941a on the reference plane 102 is 23mm to 25mm. In this application, the distance H3 between the projection of the axis of the damping cylinder 1921 on the reference plane 102 and the projection of the axis of the rotating hole 1941a on the reference plane 102 is 24mm. The above settings can prevent the distance H3 between the projection of the axis of the damping cylinder 1921 on the reference plane 102 and the projection of the axis of the rotating hole 1941a on the reference plane 102 from being too large, which would make the distance between the axis of the damping cylinder 1921 and the rotating hole 1941a too far and would be unfavorable for the installation of the damper bracket 194. It can also prevent the distance H3 between the axis of the damping cylinder 1921 and the axis of the rotating hole 1941a from being too small, which would cause the damper bracket 194 to interfere with other parts of the motorcycle 100.

[0052] like Figure 17 and Figure 18As shown, in order to reduce the size of the front tube 114 of the motorcycle 100 (refer to...) Figure 14To improve the assembly performance of the motorcycle 100, the mounting bracket 1941 is fixedly connected to the fixed bracket 115 at the mounting point on the front tube 114. However, this can easily lead to interference between the mounting bracket 1941 and the fixing points of the fuel tank 181 and the frame 11. As another implementation, the motorcycle 100 also includes a mounting assembly 22, which is fixedly connected to the fixed bracket 115, and the mounting bracket 1941 is fixedly connected to the mounting assembly 22. Mounting assembly 22 includes a fixing sleeve 221, which at least partially passes through a fixing bracket 115 and is fixedly connected to the fixing bracket 115 by welding. The fixing sleeve 221 has a through hole 2211. The fuel tank 181 also includes a fuel tank bracket 1812 located at the rear of the head tube 114. The body panel 12 also includes a fuel tank cover 122, which is at least partially located above the fuel tank 181 and is used to protect the fuel tank 181 from direct damage. Fuel leakage occurs. The fuel tank bracket 1812, fuel tank cover 1122, and mounting bracket 1941 are distributed along the height direction of the motorcycle 100. The fuel tank bracket 1812 is provided with a fuel tank fixing hole 1812a, which is fitted onto the fixing screw sleeve 221. The mounting assembly 22 also includes a mounting bolt 222, which is bolted to the through hole 2211. The fuel tank cover 122 is provided with a connecting hole 1221, through which the mounting bolt 222 passes and is bolted to the through hole 2211. Understandably, the mounting bolt 222 is also fixedly connected to the fixing sleeve 221 through the bracket fixing hole 1941b. Therefore, in this application, the through hole 2211, the connecting hole 1221, the oil tank fixing hole 1812a, and the bracket fixing hole 1941b are coaxially arranged, that is, the mounting bolt 222 can pass through the through hole 2211, the connecting hole 1221, the oil tank fixing hole 1812a, and the bracket fixing hole 1941b at the same time, and the inner diameter of the through hole 2211 is equal to the inner diameter of the bracket fixing hole 1941b. With the above configuration, the damper bracket 194, fuel tank 181, and fuel tank cover 122 can all be connected to the mounting assembly 22 via the fixing screw sleeve 221, thereby achieving a fixed connection between the damper bracket 194, fuel tank 181, and fuel tank cover 122 and the frame 11. That is, the damper bracket 194, fuel tank 181, and fuel tank cover 122 share the same mounting point, which can reduce the number of mounting points, improve the layout of the front part of the motorcycle 100, make the front part of the motorcycle 100 more compact, and thus improve the space utilization of the motorcycle 100.Furthermore, two fixing sleeves 221 are provided and distributed along the width direction of the motorcycle 100. Correspondingly, two bracket fixing holes 19411b, connecting holes 1221, fuel tank fixing holes 1812a, and through holes 22111 are all provided and distributed along the width direction of the motorcycle 100, thereby improving the stability of the co-point installation.

[0053] Understandably, the fuel tank 181 of the motorcycle 100 is an important energy storage component, and therefore needs to be fixedly connected to the frame 11 to ensure its stability during motorcycle operation. However, since the fuel tank 181 of the motorcycle 100 is usually irregularly shaped, it is fixed to the frame 11 using a two-point or three-point fixing method. To prevent stress concentration and breakage at the connection point between the fuel tank 181 and the frame 11 during aggressive driving or driving on roads with high vibration, a flexible connection between the fuel tank 181 and the frame 11 is required. Specifically, to achieve a flexible connection between the fuel tank 181 and the frame 11, the mounting assembly 22 also includes a buffer sleeve 223. The buffer sleeve 223 is fitted onto the fixing sleeve 221, and the fuel tank fixing hole 1812a is fitted onto the buffer sleeve 223, that is, the buffer sleeve 223 is located between the fixing sleeve 221 and the fuel tank fixing hole 1812a. Furthermore, the buffer sleeve 223 is made of rubber. Therefore, when the frame 11 vibrates during the operation of the motorcycle 100 and the vibration is transmitted to the buffer sleeve 223, the buffer sleeve 223 can absorb the force transmitted by the vibration of the frame 11 through its own elastic deformation, and avoid transmitting the force to the fuel tank 181. This can prevent the fuel tank 181 from vibrating and causing stress concentration at the connection between the fuel tank 181 and the frame 11, thereby improving the connection stability between the fuel tank 181 and the frame 11 and increasing the service life of the fuel tank 181.

[0054] When the fuel tank fixing hole 1812a directly contacts the buffer sleeve 223, because the fuel tank 181 is made of metal and the wall thickness at the fuel tank fixing hole 1812a is small to facilitate the installation of the fuel tank 181, the contact area between the fuel tank fixing hole 1812a and the buffer sleeve 223 is small, resulting in the buffer sleeve 223 not being able to perform its buffering function well. Furthermore, the fuel tank bracket 1812 also includes a fuel tank fixing member 1812b, which is annular and installed inside the fuel tank fixing hole 1812a. The fuel tank fixing member 1812b abuts against the buffer sleeve 223. The fuel tank fixing member 1812b is made of metal, and the fuel tank fixing hole 1812a contacts the buffer sleeve 223 through the fuel tank fixing member 1812b to increase the contact area and improve the buffering effect of the buffer sleeve. Specifically, as... Figure 18As shown, a mounting groove 2231 is provided on the outer periphery of the buffer sleeve 223. The mounting groove 2231 is recessed into the through hole 2211 radially. The fuel tank fixing member 1812b is at least partially located in the mounting groove 2231 and is engaged with the mounting groove 2231. The mounting groove 2231 can restrict the movement of the fuel tank fixing member 1812b along the axial direction of the through hole 2211. With the above configuration, based on the soft connection achieved by the fuel tank 181 through the fuel tank fixing hole 1812a being fitted onto the buffer sleeve 223, the fuel tank 181 further improves the connection stability between the fuel tank bracket 1812 and the buffer sleeve 223 by the abutment between the fuel tank fixing member 1812b and the mounting groove 2231 of the buffer sleeve 223, thereby improving the connection stability between the fuel tank 181 and the bracket. Furthermore, the contact area between the fuel tank fixing member 1812b and the mounting groove 2231 can be increased by the abutment of the fuel tank fixing member 1812b and the buffer sleeve 223, thereby improving the connection stability between the fuel tank fixing member 1812b and the buffer sleeve 223.

[0055] Because the steering damper 192 is subjected to the torque generated by the steering handlebar 191 when the motorcycle 100 is traveling at high speed, in order to prevent the steering handlebar 191 from turning, the steering damper 192 needs to apply resistance in the opposite direction to the steering handlebar 191. During this process, the damper bracket 194 of the steering damper 192 needs to maintain a stable fixed connection with the frame 11 to ensure that the steering damper 192 can work normally. If the damper bracket 194 and the frame 11 are softly connected, the steering damper 192 is prone to deformation during operation, which will cause it to fail to work normally. Therefore, the damper bracket 194 needs to be rigidly connected to the frame 11. In order to satisfy the rigid connection between the damper bracket 194 and the frame 11, it is also necessary to avoid affecting the soft connection between the fuel tank 181 and the frame 11. In this embodiment, the fixed bracket 115 further includes a mounting member 224. The mounting member 224 is annular and located between the fixed screw sleeve 221 and the mounting bracket 1941. The mounting member 224 includes a mounting hole 2241. A mounting bolt 222 passes through the bracket fixing hole 1941b and the mounting hole 2241 in sequence and is bolted to the through hole 221. The axis of the mounting hole 2241 coincides with the axis of the through hole 221, and the inner diameter of the mounting hole 2241 is equal to the inner diameter of the through hole 221. Along the axial direction of the through hole 2211, the mounting hole 2241 coincides with the through hole 2211. The upper end of the mounting member 224 abuts against the mounting bracket 1941. Since the buffer sleeve 223 is shorter than the fixing sleeve 221, the lower end of the mounting member 224 can abut against the fixing sleeve 221. Furthermore, the mounting member 224 is made of metal, and both the mounting bracket 1941 and the fixing sleeve 221 are made of metal, thus achieving a rigid connection between the fixing sleeve 221 and the mounting bracket 1941. Through this configuration, the torque received by the steering damper 192 is transmitted to the mounting bracket 1941 via the adjusting bracket 1942, and then to the fixing sleeve 221 via the mounting member 224, and further to the entire vehicle frame 11. This improves the connection stability of the damper bracket 194, enabling the steering damper 192 to function normally.

[0056] Furthermore, the lower end of the mounting component 224 abuts against the buffer sleeve 223, thereby enabling the mounting component 224 to improve the connection stability between the buffer sleeve 223 and the fixed sleeve 221, preventing the buffer sleeve 223 from moving along the axial direction of the through hole 2211, and thus improving the connection stability between the oil tank 181 and the frame 11. Furthermore, a snap-fit ​​groove 2242 is formed on the outer periphery of the mounting part 224. The snap-fit ​​groove 2242 is recessed into the through hole 2211 along the axis perpendicular to the through hole 2211. Since the thickness of the fuel tank cover plate 122 is small, the mounting part 224 can at least partially pass through the connection hole 1221 and snap-fit ​​with the connection hole 1221. That is, the connection hole 1221 is at least partially located in the snap-fit ​​groove 2242. Since the mounting part 224 is small in size, and after the mounting bolt 222 is removed during the disassembly of the motorcycle 100, the mounting part 224 has no connection relationship with other parts. Therefore, snapping the mounting part 224 into the connection hole 1221 can effectively prevent the loss of the mounting part 224, simplify the installation process when installing at the same point, and improve assembly efficiency.

[0057] As described above, when the fuel tank 181, fuel tank cover 122, and damper bracket 194 are fixedly connected to the frame 11 via the mounting assembly 22, the following steps are required for installation:

[0058] Before installation, the following components need to be pre-installed: the fuel tank fastener 1812b is snapped onto the buffer screw sleeve 223 through the mounting groove 2231, and the mounting part 224 is snapped onto the connection hole 1221 of the fuel tank cover plate 122 through the snap-fit ​​groove 2242.

[0059] Step S1: Fix the fixing sleeve 221 in the mounting assembly 22 to the frame 11 by welding;

[0060] Step S2: Fit the buffer sleeve 223 onto the fixing sleeve 221.

[0061] Step S3: The fuel tank fixing hole 1812a is fitted onto the buffer screw sleeve 223 through the fuel tank fixing part 1812b to achieve a soft connection between the fuel tank 181 and the frame 11.

[0062] Step S4: Install the fuel tank cover plate 122 so that the mounting part 224 abuts against the fixing screw sleeve 221, and make the mounting hole 2241 coincide with the through hole 2211 along the axial direction of the through hole 2211;

[0063] Step S5: Abut the mounting bracket 1941 against the mounting part 224, and make the bracket fixing hole 1941b coincide with the mounting hole 2241 and the through hole 2211;

[0064] Step S6: Pass the mounting bolt 222 through the bracket fixing hole 1941b and the mounting hole 2241 and bolt it to the through hole 2211 so that the damper bracket 104, the oil tank cover plate 122, and the oil tank 181 can be installed at the same point as the frame 11 through the bolt connection of the mounting bolt 222 and the fixing sleeve 221.

[0065] It should be noted that because the mounting bolt 222 needs to pass through the bracket fixing hole 1941b, the connecting hole 1221, and the through hole 2211 simultaneously, the mounting bolt 222 of this application is relatively long. For motorcycles 100 that do not have a steering damper 192 installed, it can also refer to... Figure 19 The mounting bolt 222 shown in the figure can be replaced with a shorter mounting bolt 222 to meet the needs of the motorcycle 100 without the steering damper 192. In this case, the mounting bolt 222 only achieves the common point installation of the fuel tank cover 122, the fuel tank 181 and the frame 11.

[0066] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
