[0031] In order to enable people in this field to better understand the solution of the present application, the technical solution in the specific implementation of the present application will be clearly and completely described below in conjunction with the drawings in the implementation of the present application.

[0032] like Figure 1A motorcycle 100 is shown, which includes a frame 11, a body covering 12, a running assembly 13, a power assembly 14 and a suspension assembly 15. The frame 11 constitutes the basic framework of the motorcycle 100, and the frame 11 is mainly used to provide support for other components of the motorcycle 100. The body covering 12 is at least partially connected to the frame 11, and the body covering 12 is used to protect the internal parts of the motorcycle 100. The running assembly 13 is at least partially located below the frame 11 and is connected to the frame 11 through the suspension assembly 15. The running assembly 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 the power assembly 14 is transmission-connected to the running assembly 13. The power assembly 14 is used to generate a driving force to drive the motorcycle 100 to move. In order to clearly illustrate the technical solution of the present application, it is also defined as follows Figure 1 It is understood that the length direction in the embodiment of the present application 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.

[0033] like Figure 2 and Figure 3 As shown, the motorcycle 100 further includes a fuel assembly 16, which includes a fuel tank 161 (see Figure 1 ), carbon canister 162, solenoid valve 163 and two-way valve 164, taking the four-cylinder engine of the present application as an example, the frame 11 includes a transverse support frame 111 extending substantially along the length direction of the motorcycle 100 (refer to Figure 6 ) and a longitudinal support frame 112 extending substantially in the height direction of the motorcycle 100 (see Figure 6 ), the frame 11 further includes a head tube 113, a fuel tank 161 is located behind the head tube 113 and is fixedly connected to the frame 11, the fuel tank 161 is also at least partially located above the cross support frame 111, the power assembly 14 includes an engine 141 (refer to Figure 1), the fuel tank 161 is connected to the engine 141 and is used to provide energy for the engine 141. The fuel in the fuel tank 161 generates fuel vapor due to changes in ambient temperature, and the fuel vapor is directly discharged back to pollute the environment. The carbon canister 162 connects the fuel tank 161 and the engine 141 through a pipeline, and is mainly used to collect and store fuel vapor to reduce the pollution to the air caused by fuel evaporation; the solenoid valve 163 connects the carbon canister 162 and the throttle of the engine 141 to control the fuel entering the engine 141 by opening or closing; the two-way valve 164 connects the fuel tank 161 and the carbon canister 162, so that when the fuel vapor pressure is greater than the set pressure, the valve of the two-way valve 164 opens, and the fuel vapor enters the carbon canister 162 and is adsorbed by the activated carbon; when the internal pressure of the fuel tank 161 is lower than the set pressure, the valve of the two-way valve 164 opens, and the outside air enters the fuel tank 161 through the carbon canister 162 to replenish and balance the internal pressure of the fuel tank 161. Specifically, the fuel assembly 16 further includes a mounting bracket 165, the mounting bracket 165 being at least partially located above the cross support frame 111, the mounting bracket 165 being located between the fuel tank 161 and the engine 141, and the suspension assembly 15 including a shock absorber 151 (see FIG. Figure 6 ), the mounting bracket 165 is also located above the shock absorber 151, and the carbon canister 162, the solenoid valve 163 and the two-way valve 164 are all arranged on the mounting bracket 165. Along the width direction of the motorcycle 100, the body cover 12 is at least partially located on both sides of the fuel assembly 16, and the mounting bracket 165 is fixedly connected to the body cover 12 located on both sides of the mounting bracket 165. The mounting bracket 165 of the present application is recessed downward along the height direction of the motorcycle 100 to form a groove body, and the carbon canister 162, the solenoid valve 163 and the two-way valve 164 are arranged in the groove body, so that the inner wall of the groove body has a certain protective effect on the carbon canister 162, the solenoid valve 163 and the two-way valve 164.

[0034] Furthermore, the vehicle body covering 12 includes inner lining plates 121 distributed on both sides of the engine 141. The inner lining plates 121 include a first lining plate 1211 and a second lining plate 1212 distributed along the width direction of the motorcycle 100. Both ends of the mounting bracket 165 are fixedly connected to the first lining plate 1211 and the second lining plate 1212. In this application, bolt holes are provided on the mounting bracket 165, the first lining plate 1211 and the inner lining plate 121. The mounting bracket 165 is fixedly connected to the first lining plate 1211 and the second lining plate 1212 by bolts, and the mounting bracket 165 is fixedly connected to the first lining plate 1211 or the second lining plate 1212. The connection point of liner 1212 is close to the connection point between the first liner 1211 or the second liner 1212 and the vehicle frame 11, allowing the mounting bracket 165 to be connected to the vehicle frame 11 through the first liner 1211 or the second liner 1212. This allows the load of the mounting bracket 165 to be transferred to the vehicle frame 11 through the first liner 1211 or the second liner 1212, that is, the frame 11 provides support for the mounting bracket 165. This not only improves the connection stability of the mounting bracket 165, but also avoids the need for mounting points on the vehicle frame 11, reducing the number of mounting points on the vehicle frame 11 and facilitating the processing of the vehicle frame 11. Through the above arrangement, the carbon canister 162, the solenoid valve 163, and the two-way valve 164 are arranged in the same area via the mounting bracket 165. Compared to separately arranging each component, this not only facilitates maintenance and improves serviceability, but also allows each component to be arranged close to the fuel tank 161 and the power assembly 14, facilitating the layout of wiring harnesses and pipelines and reducing the length of the pipelines. Furthermore, the engine 141 includes a cylinder head 1411 and an upper crankcase 1412. The cylinder head 1411 is at least partially located above and in front of the upper crankcase 1412. Since the engine 141 of the present application is a four-cylinder engine, and the four-cylinder engine of the present application is a parallel four-cylinder engine, the cylinder head 1411 of the engine 141 is located relatively forward. Therefore, a layout space can be formed between the cylinder head 1411 and the upper crankcase 1412. This layout space is located behind the cylinder head 1411 and above the upper crankcase 1412 for arranging and connecting the mounting bracket 165, thereby making the layout of the motorcycle 100 more compact and improving the space utilization of the motorcycle 100. For conventional two-cylinder engines, an air filter is usually required at the rear of the engine 141. Therefore, the mounting bracket 165 of the present application is mainly suitable for motorcycles 100 equipped with four-cylinder engines.

[0035] like Figure 3 and Figure 4As shown, in this embodiment, the mounting bracket 165 is provided with a solenoid valve plug-in portion 1651 and a two-way valve plug-in portion 1652, the solenoid valve 163 is provided with a solenoid valve plug-in interface 1631, and the two-way valve 164 is provided with a two-way valve plug-in interface 1641, so that the solenoid valve 163 is connected to the mounting bracket 165 by plugging the solenoid valve plug-in interface 1631 and the solenoid valve plug-in portion 1651, and the two-way valve 164 is connected to the mounting bracket 165 by plugging the two-way valve plug-in interface 1641 and the two-way valve plug-in portion 1652. Furthermore, a carbon canister plug-in portion 1653 is provided on the mounting bracket 165, and a carbon canister connector 1621 is provided on the carbon canister 162. A ring structure is provided at one end of the carbon canister connector 1621, and a carbon canister plug-in interface is provided on the other end. When the carbon canister 162 is installed, the carbon canister connector 1621 is firstly put on the carbon canister 162 through the ring structure, and then the carbon canister connector 1621 is connected to the mounting bracket 165 through the connection between the carbon canister plug-in interface and the carbon canister plug-in portion 1653, thereby realizing the connection between the carbon canister 162 and the mounting bracket 165. Through the above-mentioned setting, the solenoid valve 163 and the two-way valve 164 are connected to the mounting bracket 165 by plugging, thereby improving the disassembly and assembly efficiency of the carbon canister 162, the solenoid valve 163 and the two-way valve 164. During the maintenance of the carbon canister 162, the solenoid valve 163 and the two-way valve 164, it is only necessary to pull out the carbon canister 162, the solenoid valve 163 and the two-way valve 164 for maintenance. After the maintenance is completed, it is only necessary to insert the carbon canister 162, the solenoid valve 163 and the two-way valve 164 back into the mounting bracket 165, thereby improving the maintenance performance of the carbon canister 162, the solenoid valve 163 and the two-way valve 164.

[0036] like Figure 4 and Figure 5 As shown, further, the solenoid valve plug portion 1651 is at least partially located above the two-way valve plug portion 1652. When viewed along the width direction of the motorcycle 100, the solenoid valve plug portion 1651 and the two-way valve plug portion 1652 at least partially overlap, defining a horizontal plane 101 perpendicular to the height direction of the motorcycle 100 (refer to Figure 6), and then define a reference plane 102, the bottom surface of the groove formed by the mounting bracket 165 is basically located on the reference plane 102, and in the present application, the mounting bracket 165 is basically distributed along the height direction of the motorcycle 100, so that the reference plane 102 is basically parallel to the horizontal plane 101, and the difference between the minimum distance H1 between the uppermost end of the solenoid valve plug-in portion 1651 and the reference plane 102 and the minimum distance H2 between the uppermost end of the two-way valve plug-in portion 1652 and the reference plane 102 is greater than or equal to 6.3 mm and less than or equal to 8.8 mm. Furthermore, the difference between the minimum distance H1 between the uppermost end of the solenoid valve plug-in portion 1651 and the reference plane 102 and the minimum distance H2 between the uppermost end of the two-way valve plug-in portion 1652 and the reference plane 102 is greater than or equal to 7 mm and less than or equal to 8.8 mm. In the embodiment of the present application, the difference between the minimum distance H1 between the uppermost end of the solenoid valve plug-in portion 1651 and the reference plane 102 and the minimum distance H2 between the uppermost end of the two-way valve plug-in portion 1652 and the reference plane 102 is 7.5 mm. Through the above arrangement, the solenoid valve plug-in portion 1651 and the two-way valve plug-in portion 1652 are distributed along the height direction of the motorcycle 100. Therefore, after the solenoid valve 163 and the two-way valve 164 are installed, the layout space occupied by the solenoid valve 163 and the two-way valve 164 in the mounting bracket 165 can be reduced, thereby improving the space utilization of the fuel assembly 16. In addition, the distribution of the solenoid valve 163 and the two-way valve 164 along the height direction of the motorcycle 100 can also prevent different pipelines from being entangled, thereby facilitating the pipeline layout of the fuel assembly 16.

[0037] like Figure 3 and Figure 4 As shown, in this embodiment, the carbon canister 162 is also provided with a drain pipe 1622. One end of the drain pipe 1622 is connected to the carbon canister 162, and the other end of the drain pipe 1622 is connected to the outside world. The drain pipe 1622 is used to drain water generated by the combustion of fuel vapor. The bottom of the mounting bracket 165 is provided with a plurality of through holes 1654. This reduces the weight of the mounting bracket 165 while also providing space for the layout of pipes and wiring harnesses. This eliminates the need for detours during the arrangement of the pipes and wiring harnesses, thereby reducing the length of the pipes and wiring harnesses and facilitating their arrangement. In this application, the drain pipe 1622 can be directly passed through the through holes 1654, thereby reducing the length of the drain pipe 1622. In addition, the through holes 1654 can quickly drain water if it accidentally enters the mounting bracket 165, preventing water from remaining in the mounting bracket 165 for a long time and causing damage to the carbon canister 162, the solenoid valve 163, and the two-way valve 164, thereby affecting the normal operation of the carbon canister 162.

[0038] In this embodiment, the mounting bracket 165 is made of plastic, thereby reducing the weight of the mounting bracket 165. After the mounting bracket 165 is connected to the first lining plate 1211 and the second lining plate 1212, the pressure applied by the mounting bracket 165 to the first lining plate 1211 and the second lining plate 1212 is reduced, thereby preventing stress concentration at the connection point between the mounting bracket 165 and the first lining plate 1211 and the second lining plate 1212 due to excessive pressure, which may cause damage to the connection point. The mounting bracket 165 can also be made of metal. When the mounting bracket 165 is made of metal, the mounting bracket 165 can be directly connected to the vehicle frame 11, thereby improving the connection stability of the mounting bracket 165.

[0039] like Figure 6 and Figure 7As shown, the motorcycle 100 also includes an electrical component 17, which is mainly used to assist the driver in operating the motorcycle 100. The electrical component 17 includes a main wiring harness 171 for connecting electrical appliances and a power source. The main wiring harness 171 basically extends along the length of the motorcycle 100, and each electrical device is electrically connected to the main wiring harness 171, so that the power source can supply power to each electrical appliance through the main wiring harness 171. The electrical component 17 includes a rectifier 172, which is used to convert AC current into DC power to provide a stable power supply for the vehicle's electrical appliances. As an embodiment, the rectifier 172 is located on the rear side of the power component 14, and the electrical component 17 also includes a battery 173. The rectifier 172 is located in front of the battery 173, and the rectifier 172 is electrically connected to the battery 173, so that the length of the line can be reduced. Specifically, the frame 11 includes a connecting bracket 114 located behind the longitudinal support frame 112, the connecting bracket 114 extends basically along the length direction of the motorcycle 100 and the connecting bracket 114 is fixedly connected to the longitudinal support frame 112, the longitudinal support frame 112 is also located below the fuel tank 161, the rectifier 172 is at least partially located behind the longitudinal support frame 112, the rectifier 172 is also at least partially located below the fuel tank 161, the connecting bracket 114 is formed with a bracket accommodating space 1141, the rectifier 172 and the battery 173 are both at least partially located in the bracket accommodating space 1141, the body cover 12 includes a frame bottom plate 122, the frame bottom plate 122 is located below the connecting bracket 114 and is fixedly connected to the connecting bracket 114, the battery 173 is also fixedly connected to the frame bottom plate 122, and the connection point between the fuel tank 161 and the connecting bracket 114 is defined as Fuel tank mounting point 1611, the fuel tank 161 and the connecting bracket 114 are fixedly connected through the fuel tank mounting point 1611, the fuel tank mounting point 1611 is a sheet metal part fixedly connected to the connecting bracket 114, in the present application, the fuel tank mounting point 1611 and the connecting bracket 114 are fixedly connected by welding, the connecting bracket 114 also includes a rectifier bracket 1142, the rectifier 172 is fixedly connected to the rectifier bracket 1142, the rectifier bracket 1142 is fixedly connected to the connecting bracket 114 through the fuel tank mounting point 1611, that is, the rectifier bracket 1142 and the fuel tank 161 are fixedly connected to the connecting bracket 114 by a common point mounting manner, the connection point between the frame floor 122 and the connecting bracket 114 is defined as the floor mounting point 1221, the rectifier bracket 1142 is also fixedly connected to the frame floor 122 through the floor mounting point 1221. Furthermore, the motorcycle 100 includes a saddle assembly 18, which includes a main cushion 181. The main cushion 181 is located above the connecting bracket 114, and the main cushion 181 is fixedly connected to the fuel tank 161 and the connecting bracket 114. When viewed along the height direction of the motorcycle 100, the rectifier 172 is at least partially located below the main cushion 181, and the rectifier 172 is also at least partially located above the shock absorber 151.Through the above arrangement, the rectifier 172 is located below the fuel tank 161, which can not only utilize the idle space, thereby improving the space utilization rate of the motorcycle 100, but also is arranged close to the battery 173, which is also beneficial to the arrangement of the wiring harness. In addition, the common point installation method can reduce the arrangement of the connection points, which is beneficial to the connection of the rectifier 172.

[0040] As one embodiment, when viewed along the width of the motorcycle 100, the rectifier bracket 1142 is arranged at an angle, with the base plate mounting point 1221 located forward of and below the fuel tank mounting point 1611. In this application, the rectifier bracket 1142 is arranged in a strip shape and extends substantially along a predetermined plane 103. Specifically, the angle η between the predetermined plane 103 and the horizontal plane 101 is greater than or equal to 31° and less than or equal to 47°. Furthermore, the angle η between the predetermined plane 103 and the horizontal plane 101 is greater than or equal to 35° and less than or equal to 43°. In this embodiment, the angle η between the predetermined plane 103 and the horizontal plane 101 is 39°. The above arrangement can avoid the angle η being too large, which would cause interference between the rectifier 172 and the fuel tank 161 or the battery 173, and can also avoid the angle η being too small, which would cause insufficient space for arranging the rectifier 172. Thus, while avoiding interference between the rectifier 172 and other components, the arrangement space can be fully utilized, thereby improving the space utilization rate of the motorcycle 100.

[0041] In this embodiment, the rectifier bracket 1142 is provided with a rectifier mounting hole 1142a, and the rectifier 172 is fixedly connected to the rectifier bracket 1142 through the rectifier mounting hole 1142a. Specifically, two rectifier mounting holes 1142a are provided, and the two rectifier mounting holes 1142a are distributed along the length of the motorcycle 100. The two rectifier mounting holes 1142a are arranged near the bottom plate mounting point 1221 and the fuel tank mounting point 1611. It can be understood that the rectifier mounting holes 1142a near the bottom plate mounting point 1221 and the fuel tank mounting point 1611 can make the connection between the rectifier 172 and the rectifier bracket 1142 more stable, thereby improving the connection stability between the rectifier 172 and the rectifier bracket 1142 and preventing the rectifier 172 from falling off the rectifier bracket 1142 under extreme operating conditions. Furthermore, rectifier bracket 1142 is provided with a weight-reducing hole 1142b located between the two rectifier mounting holes 1142a. This reduces the weight of rectifier bracket 1142, thereby increasing the lightweightness of motorcycle 100. It also prevents weight-reducing holes 1142b from affecting the connection strength of rectifier mounting holes 1142a, thereby improving the connection stability between rectifier 172 and rectifier bracket 1142. Furthermore, rectifier bracket 1142 is made of metal, which has a higher structural strength, thereby improving the connection stability between rectifier 172 and rectifier bracket 1142.

[0042] like Figure 8 and Figure 9As shown, the electrical component 17 also includes a rear taillight 174 located at the rear of the motorcycle 100. The rear taillight 174 includes a light-emitting component 1741 and a taillight wiring harness 1742. The light-emitting component 1741 is electrically connected to the main wiring harness 171 through the taillight wiring harness 1742. During the installation of the rear taillight 174, it is usually necessary to first connect the taillight wiring harness 1742 and the main wiring harness 171, and then arrange the light-emitting component 1741 and other components at the rear of the motorcycle 100. This method makes the routing of the taillight wiring harness 1742 very inconvenient. As an embodiment, the frame 11 includes a rear frame 115 located at the rear of the motorcycle 100. The rear frame 115 is located behind the connecting bracket 114 and is fixedly connected to the connecting bracket 114. The rear frame 115 includes a fixed sheet metal 1151 located at the lower portion of the rear frame 115. The fixed sheet metal 1151 is used to fix the rear fender of the motorcycle 100. The fixed sheet metal 1151 is provided with a threading hole 1151c on one side of the fixed sheet metal 1151 along the width direction of the motorcycle 100. The taillight harness 1742 is connected to the main harness 171 after passing through the threading hole 1151c. Through the above arrangement, the taillight harness 1742 of the present application is routed through the threading hole 1151c on one side of the fixed sheet metal 1151, thereby ensuring that the layout of the taillight harness 1742 is not affected by the layout of other components and preventing interference between the layout of the taillight harness 1742 and other components. This optimizes the installation process of the various components at the rear of the motorcycle and improves the assembly performance of the motorcycle.

[0043] In one embodiment, the taillight wiring harness 1742 extends forward along the length of the motorcycle 100. The fixed sheet metal 1151 includes two side sheet metals 1151a distributed along the width of the motorcycle 100 and a bottom sheet metal 1151b connecting the two side sheet metals 1151a. The bottom sheet metal 1151b is located between the two side sheet metals 1151a, and threading holes 1151c are provided in the side sheet metals 1151a. The taillight wiring harness 1742 is provided with threading holes 1151c along the width of the motorcycle 100, extending from the side of the side sheet metals 1151a away from the bottom sheet metal 1151b, and is connected to the main wiring harness 171. The taillight wiring harness 1742 also includes a wiring harness connector 1742a, which electrically connects the taillight wiring harness 1742 to the main wiring harness 171.

[0044] As an embodiment, the electrical component 17 also includes a diagnostic interface 175 and a fuse box 176. The fuse in the fuse box 176 will burn out or automatically disconnect when the circuit is short-circuited or the load is too large. It will be restored after the fault is eliminated. Its purpose is to protect other electrical appliances from damage to avoid causing greater failures. The diagnostic interface 175 can support maintenance personnel to perform diagnosis through diagnostic tools. In this application, the diagnostic interface 175 refers to the OBD (OBD, On-Board Diagnostics, vehicle self-diagnostic system) diagnostic port. By connecting to various sensors and actuators of the motorcycle 100, it collects vehicle operation data in real time and monitors the operating status of the engine 141 and the working status of the exhaust treatment system in real time. The diagnostic interface 175 is located behind the fuse box 176. The saddle assembly 18 also includes a secondary seat cushion 182 (refer to Figure 1 ), the auxiliary seat cushion 182 is located behind the main seat cushion 181, and the fuse box 176 is located below the auxiliary seat cushion 182. In this embodiment, the rear frame 115 also includes an electrical bracket 1152. The diagnostic interface 175 is fixedly connected to the electrical bracket 1152 via fasteners. The electrical bracket 1152 is provided with a rubber cover 1152b, and the fuse box 176 is fixedly connected to the electrical bracket 1152 via the rubber cover 1152b. Specifically, the electrical bracket 1152 is provided with an electrical mounting hole 1152a, and the electrical bracket 1152 is fixedly connected to the fixed sheet metal 1151 through the electrical mounting hole 1152a. When viewed from the height of the motorcycle, the taillight wiring harness 1742 is located between the electrical bracket 1152 and the fixed sheet metal 1151. Through the above-mentioned setting, in the present application, the diagnostic interface 175 is fixedly connected to the electrical bracket 1152 by self-tapping screws, thereby improving the connection stability between the diagnostic structure and the electrical bracket 1152, and the fuse box 176 is connected to the electrical bracket 1152 by the rubber sleeve 1152b, thereby preventing the fuse in the fuse box 176 from breaking due to vibration during the driving of the motorcycle 100, thereby preventing the motorcycle 100 from losing power.

[0045] like Figure 9 and Figure 10As shown, in this embodiment, the fixed sheet metal 1151 also includes a protective ring 1151d, which is snap-fitted to the threading hole 1151c. The protective ring 1151d is an annular structure, and the taillight wiring harness 1742 is passed through the protective ring 1151d. Furthermore, the outer periphery of the protective ring 1151d is provided with an annular protective slot 1151e, which is snap-fitted to the threading hole 1151c. In this application, the material of the protective ring 1151d is rubber. Through the above-mentioned setting, the rubber protective ring 1151d is softer and easier to deform, thereby facilitating the connection between the protective ring 1151d and the wire threading hole 1151c. In addition, since the fixed sheet metal 1151 is made of metal, the protective ring 1151d can also prevent the wire threading hole 1151c from cutting the taillight wiring harness 1742, thereby preventing the taillight wiring harness 1742 from being damaged due to the cutting action of the wire threading hole 1151c for a long time, thereby improving the service life of the taillight wiring harness 1742.

[0046] like Figure 11 and Figure 12As shown, to prevent sediment from accumulating on the rear wheel 132 during driving, to prevent exposed components on the rear wheel 132, and to improve the appearance of the motorcycle 100, a rim cover 123 is typically provided on the rear rim 1321 to block sediment. In the prior art, the rim cover 123 is typically bolted to the rear rim 1321, making the installation process relatively cumbersome. Without the rim cover 123, sediment easily accumulates in the mounting holes of the rim cover 123. As an embodiment, in the present application, a rim snap-fitting groove 1321a is provided on the rear rim 1321, and a projection plane 104 perpendicular to the rotation axis of the rear wheel 132 is defined. The projection of the rim snap-fitting groove 1321a on the projection plane 104 is defined as the snap-fitting groove projection. The snap-fitting groove projection is basically circular, and the center of the snap-fitting groove projection basically coincides with the projection of the rotation axis of the rear wheel 132 on the projection plane 104. A plurality of snap-fitting portions 1231 are provided on the rim cover 123, and the plurality of snap-fitting portions 1231 are snap-fitted with the rim snap-fitting groove 1321a. The projection of the snap-fitting portion 1231 on the projection plane 104 is defined as the snap-fitting portion projection. When viewed along the width direction of the motorcycle 100, the snap-fitting portion projection and the snap-fitting groove projection at least partially overlap. Several engaging portions 1231 are located on the inner side of the rim cover 123. That is, when the rim cover 123 and the rear rim 1321 are assembled, the engaging portions 1231 are not directly visible when viewed across the width of the motorcycle 100, thereby improving the appearance of the rim cover 123. Furthermore, the rim cover 123 includes a left rim cover 1232 and a right rim cover 1233, located along the width of the motorcycle 100. The right rim cover 1233 has a connecting hole 1233a disposed on its inner side, while the left rim cover 1232 has a connecting portion 1232a disposed on its inner side. The connecting holes 1233a and connecting portion 1232a are connected by fasteners. It is understood that the connecting holes 1233a may also be disposed on the left rim cover 1232, and the connecting portion 1232a may also be disposed on the right rim cover 1233. In addition, a reinforcing rib 1234 is provided on the inner side of the rim cover 123. The reinforcing rib 1234 is at least partially located on the connecting portion 1232a, thereby improving the structural strength of the connecting portion 1232a and enhancing the connection stability of the rim cover 123. Through the above arrangement, the rim cover 123 of the present application is mounted on the rear rim 1321 by snapping, and the circumferentially extending rim snapping groove 1321a ensures that the snapping of the snapping portion 1231 is not restricted to a fixed position. The rim cover 123 can be installed at any position. It is only necessary to align the connecting hole 1233a with the connecting portion 1232a during installation. This improves the assembly efficiency of the rim cover 123 and the rear rim 1321 and enhances the assembly performance of the rim cover 123.

[0047] In this embodiment, the clamping portions 1231 are centrally symmetrical about the axis of the rear wheel 132 when viewed along the width of the motorcycle 100. Furthermore, the number of clamping portions 1231 is greater than or equal to 3 and less than or equal to 9. Specifically, the number of clamping portions 1231 is greater than or equal to 5 and less than or equal to 7. In the present application, the number of clamping portions 1231 is 6. This arrangement avoids both the poor connection stability between the rim cover 123 and the rear rim 1321 caused by a small number of clamping portions 1231 and the inconvenience of assembly and disassembly between the rim cover 123 and the rear rim 1321 caused by an excessive number of clamping portions 1231. This improves the ease of assembly of the rim cover 123 and the rear rim 1321 while ensuring sufficient connection strength between the rim cover 123 and the rear rim 1321.

[0048] In this embodiment, the clamping portion 1231 includes a first clamping portion 1231a and a second clamping portion 1231b. The second clamping portions 1231b are located on either side of the first clamping portion 1231a along the circumference of the rear wheel 132. Therefore, during installation, the first clamping portion 1231a is used to complete the installation first, and the second clamping portions 1231b are used to securely connect the rim cover 123 to the rear rim 1321. This arrangement allows the second clamping portions 1231b to further secure the rim cover 123 to the rear rim 1321, thereby improving the connection stability between the rim cover 123 and the rear rim 1321 and preventing the rim cover 123 from falling off the rear rim 1321 when the motorcycle is under extreme operating conditions, thereby improving the driving safety of the motorcycle 100.

[0049] In one embodiment, the rim cover 123 is provided with an inspection opening 1235, which is covered by an inspection cover 1235a. The inspection cover 1235a is snap-fitted to the inspection opening 1235. Specifically, a quick-release opening 1236 is provided on the side of the inspection opening 1235 near the rotation axis of the rear wheel 132. The quick-release opening 1236 is recessed inward along the width direction of the motorcycle 100, allowing the driver to quickly open the inspection cover 1235a through the quick-release opening 1236 to inspect the interior of the rim cover 123. With this arrangement, the quick-release opening 1236 allows the driver to manually remove the inspection cover 1235a without using tools when inspecting the interior of the rim cover 123. Furthermore, if the rim cover 123 is damaged and difficult to remove, the rim cover 123 can be removed from the inside of the rim cover 123 through the inspection opening 1235, thereby improving the maintainability of the rim cover 123.

[0050] In this embodiment, an abutment portion 1237 is further provided on the inner side of the rim cover 123. The rear wheel 132 also includes a rear hub 1322. The abutment portion 1237 abuts against the rear hub 1322, thereby enhancing the structural strength of the rim cover 123 while maintaining a secure connection. The abutment portion 1237 also serves as a positioning mechanism for the installation of the rim cover 123. Furthermore, the rim cover 123 is made of plastic, thereby reducing the overall weight of the motorcycle 100. The "inner side" mentioned above refers to the space between the left rim cover 1232 and the right rim cover 1233 when the rim cover 123 and the rear rim 1321 are assembled.

[0051] like Figure 13 、 Figure 14 and Figure 15 As shown, motorcycle 100 also includes a steering handle 19. During the sales process, motorcycle 100 needs to be transported from the manufacturer to a distributor, or after the consumer purchases motorcycle 100, motorcycle 100 also needs to be transported. During transportation, motorcycle 100 needs to be secured to a fixing bracket 200 to prevent motorcycle 100 from moving during transportation. Typically, the steering handle 19 of motorcycle 100 is the largest component of the motorcycle 100 in its width direction. The steering handle 19 is easily bumped during transportation and increases the packaging size of motorcycle 100. Therefore, the steering handle 19 needs to be removed during transportation of motorcycle 100 and reinstalled after transportation is completed.

[0052] like Figure 14 and Figure 15 As shown, as an embodiment, the steering handle 19 includes a steering handle tube 191 which is basically a round tube. The steering handle 19 is connected to the fixing bracket 200 through a fixing mechanism 300, wherein the fixing mechanism 300 includes a first fixing portion 31, a second fixing portion 32 and a connecting member 33. The first fixing portion 31 and the second fixing portion 32 are connected by the connecting member 33. The first fixing portion 31 and the second fixing portion 32 are both basically hollow cylindrical. In this application, the connecting member 33 can be a bolt connecting member 33. The connecting member 33 passes through the first fixing portion 31 and is connected to the second fixing portion 32. The outer diameters of the first fixing portion 31 and the second fixing portion 32 are smaller than the inner diameter of the steering handle tube 191, and the inner diameters of the first fixing portion 31 and the second fixing portion 32 are equal and larger than the outer diameter of the connecting member 33. Specifically, the first fixing portion 31 and the second fixing portion 32 are at least partially located in the steering tube 191 , and the first fixing portion 31 and the second fixing portion 32 can move in the steering tube 191 along the axial direction of the steering tube 191 by tightening and loosening the connecting piece 33 .

[0053] Among them, the connecting member 33 includes a loosened state and a tightened state. When the connecting member 33 enters the tightened state from the loosened state, the first fixing portion 31 and the second fixing portion 32 approach each other until they abut. When the connecting member 33 is in the tightened state and the tightening operation continues, since the inner diameters of the first fixing portion 31 and the second fixing portion 32 are larger than the outer diameter of the connecting member 33, and the abutting surfaces 105 of the first fixing portion 31 and the second fixing portion 32 are inclined relative to the axis of the steering tube 191, the second fixing portion 32 is displaced radially toward the steering tube 191 along the abutting surface 105, and the axis of the second fixing portion 32 is parallel to the axis of the connecting member 33, so that the first fixing portion 31 and the second fixing portion 32 are misaligned or have a tendency to be misaligned. At this time, the first fixing portion 31 and the second fixing portion 32 apply pressure to the inner wall of the steering tube 191 along the radial direction of the steering tube 191, thereby realizing a fixed connection between the steering tube 191 and the fixing mechanism through the pressure of the first fixing portion 31 and the second fixing portion 32.

[0054] Specifically, since the abutment surface 105 is tilted relative to the axis of the steering handlebar tube 191, an angle is formed between the abutment surface 105 and the axis of the steering handlebar tube 191, which is an acute angle formed by the abutment surface 105 and the axis of the steering handlebar tube 191, wherein the angle γ between the abutment surface 105 and the axis of the steering handlebar tube 191 is greater than or equal to 30° and less than or equal to 50°. In the present application, the angle γ between the abutment surface 105 and the axis of the steering handle tube 191 is 40°, so that the abutment surface 105 of the first fixing portion 31 and the second fixing portion 32 is arranged at an angle in the axial direction of the steering handle tube 191. When the connecting member 33 is in a tightened state, as the connecting member 33 is tightened, the first fixing portion 31 and the second fixing portion 32 are displaced along the abutment surface 105, so that the first fixing portion 31 and the second fixing portion 32 can apply pressure to the inner wall of the steering handle tube 191, and realize the fixed connection between the fixing mechanism 300 and the steering handle 19 through pressure.

[0055] Furthermore, the fixing mechanism 300 further includes an extension portion 34, which is located at an end of the first fixing portion 31 away from the steering handle 19 and is fixedly connected to the first fixing portion 31. The extension direction of the extension portion 34 is perpendicular to the axial direction of the steering handle tube 191. The extension portion 34 is provided with a fixing hole 341, which is connected to the fixing bracket 200 via a connector 33. Through the above arrangement, in the present application, by locking the steering handle 19 of the motorcycle 100 and then fixing it to the fixing bracket 200 via the fixing mechanism 300, the steering handle 19 does not need to be disassembled during transportation of the motorcycle 100, thereby improving the convenience of packaging the motorcycle 100. In addition, locking the steering handle 19 can also prevent the handle from being damaged during transportation, thereby improving the convenience of transporting the motorcycle 100.

[0056] In this embodiment, the first fixing portion 31 and the second fixing portion 32 are substantially cylindrical with the same outer diameter, and the outer diameters of the first fixing portion 31 and the second fixing portion 32 are the same as the inner diameter of the handlebar tube 191. Specifically, a stepped hole 311 is provided along the axis of the first fixing portion 31. The stepped hole 311 is connected to the second fixing portion 32 via a connector 33. The portion of the stepped hole 311 proximal to the second fixing portion 32 is a first through-hole 3111, while the portion distal to the second fixing portion 32 is a fixing mechanism mounting hole 3112. The diameter of the fixing mechanism mounting hole 3112 is larger than the diameter of the first through-hole 3111. This prevents the end of the connector 33 from protruding from the first fixing portion 31 when the first and second fixing portions 31 and 32 are connected, thereby facilitating the connection between the extension portion 34 and the fixing bracket 200. Furthermore, a second through-hole 321 is provided on the second fixing portion 32. The first through-hole 3111 and the second through-hole 321 are coaxial and have the same inner diameter. The first through-hole 3111 and the second through-hole 321 are threaded, and the connecting member 33 is a bolt. The connecting member 33 passes through the fixing mechanism mounting hole 3112 and then connects the first through-hole 3111 and the second through-hole 321. Furthermore, the first fixing portion 31 and the second fixing portion 32 are made of metal. In this application, the first fixing portion 31 and the second fixing portion 32 are made of carbon steel, which improves the connection stability between the steering handle 19 and the fixing bracket 200.
