[0003] In the prior art, the power assembly includes an engine. Due to the influence of the structure of the engine itself, most engines cannot be centered on the frame, resulting in the center of gravity of the motorcycle shifting, and further reducing the body stability of the motorcycle. Summary of the Utility Model

[0004] In order to solve the deficiencies of the prior art, the purpose of the present application is to provide a motorcycle with relatively high body stability.

[0005] To achieve the above purpose, the present application adopts the following technical solutions:

When the engine is offset to one side of the longitudinal central plane, the main wiring harness is located on the other side of the longitudinal central plane, and the center of gravity of the engine and the center of gravity of the main wiring harness are respectively located on both sides of the longitudinal central plane, so that the center of gravity of the motorcycle is basically located within the longitudinal plane.

Along the height direction of the frame, the main beam tube and the first support tube at least partially overlap.

[0009] Further, along the width direction of the frame, the maximum distance between the first support tube and the longitudinal central plane is defined as the first distance, and the maximum distance between the second support tube and the longitudinal central plane is defined as the second distance. The ratio range of the first distance to the second distance is 0.7 to 0.9.

[0010] Further, the motorcycle further includes a carbon canister and a fuel tank. The carbon canister is connected to the main beam tube and communicates with the fuel tank. Along the length direction of the frame, the carbon canister at least partially overlaps with the engine; along the height direction of the frame, the fuel tank at least partially overlaps with the engine; along the height direction of the frame, the carbon canister at least partially overlaps with the main wire harness.

[0011] Further, the motorcycle further includes a speed change assembly and a braking assembly. A storage space is formed among the speed change assembly, the frame and the engine. Both the braking assembly and the carbon canister are located in the storage space.

[0012] Further, along the length direction of the frame, the minimum distance range between the carbon canister and the engine is 15 cm to 25 cm.

[0022] To enable those skilled in the art to better understand the solution of this application, the technical solutions in the specific embodiments of this application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this application.

[0023] As Figure 1 and Figure 2 shown, a motorcycle 100 is provided, which includes a frame 11, a running assembly 12, a power assembly 13, a speed-changing assembly 14, and a wiring harness assembly 15. The frame 11 constitutes the basic framework of the motorcycle 100 and is used to support the running assembly 12, the power assembly 13, the speed-changing assembly 14, and the wiring harness assembly 15. The running assembly 12 includes a front wheel 121 and a rear wheel 122, and both the front wheel 121 and the rear wheel 122 are used for the movement of the motorcycle 100. The power assembly 13 is connected to the frame 11, and the power assembly 13 is drivingly connected to the running assembly 12. The power assembly 13 can drive the front wheel 121 and / or the rear wheel 122 to move. The speed-changing assembly 14 is connected to the frame 11, and the speed-changing assembly 14 is drivingly connected to the power assembly 13. The speed-changing assembly 14 can adjust the power output of the power assembly 13 to adjust the vehicle speed of the motorcycle 100. The wiring harness assembly 15 is at least partially connected to the frame 11, and the wiring harness assembly 15 is used to connect the body electrical components of the motorcycle 100. To clearly illustrate the technical solution of the application, the front, rear, left, right, up, and down as Figure 1 shown are also defined. In this application, the length direction of the motorcycle 100 refers to the above-mentioned front-rear direction, the width direction of the motorcycle 100 refers to the above-mentioned left-right direction, and the height direction of the motorcycle 100 refers to the above-mentioned up-down direction. Specifically, at least a part of the running assembly 12 is located below the frame 11.

[0024] As an implementation manner, the power assembly includes an engine 131. The engine 131 is drivingly connected to the running assembly 12, and the engine 131 can drive the front wheel 121 and / or the rear wheel 122 to move. A longitudinal central plane 101 that is perpendicular to the width direction of the frame 11 and basically bisects the frame 11 is defined. At least a part of the engine 131 passes through the longitudinal central plane 101, that is, the longitudinal central plane 101 can divide the engine 131 into left and right parts, so that the center of gravity of the motorcycle 100 is basically located within the longitudinal plane 101. It should be noted that the center of gravity of the motorcycle 100 being basically located within the longitudinal central plane 101 is beneficial to improving the body stability of the motorcycle 100, and thus beneficial to improving the driving safety of the motorcycle 100.

[0025] As Figure 3As shown, in the present embodiment, the wire harness assembly 15 includes a main wire harness 151. When the engine 131 is offset to one side of the longitudinal central plane 101, the main wire harness 151 is located on the other side of the longitudinal central plane 101, and the center of gravity of the engine 131 and the center of gravity of the main wire harness 151 are respectively located on both sides of the longitudinal central plane 101. Specifically, since the engine 131 is not a structure that is symmetric about the left and right of the longitudinal central plane 101, the present application needs to design and layout the engine 131 and the vehicle frame 11 so that the width center of the motorcycle 100 is basically located on the longitudinal central plane 101, and adjust the assembly position of the main wire harness 151 on the vehicle frame 11 so that the main wire harness 151 can balance the body imbalance caused by the center of gravity offset of the engine 131. More specifically, when the engine 131 is offset to the left side of the longitudinal central plane 101, the main wire harness 151 is arranged on the right side of the longitudinal central plane 101 to balance the center of gravity of the motorcycle 100; similarly, when the engine 131 is offset to the right side of the longitudinal central plane 101, the main wire harness 151 is arranged on the left side of the longitudinal central plane 101 to balance the center of gravity of the motorcycle 100. Through the above settings, the layout rationality of the engine 131 is improved, and at the same time, the center of gravity of the main wire harness 151 and the center of gravity of the engine 131 are balanced with each other, so that the center of gravity of the motorcycle 100 can be located on the longitudinal central plane 101, which is beneficial to improving the body stability of the motorcycle 100.

[0026] As Figure 4 shown, as an implementation manner, the vehicle frame 11 includes a main beam tube 111 that extends basically along the length direction of the vehicle frame 11. The main wire harness 151 extends basically along the length direction of the vehicle frame 11, and the main wire harness 151 is connected to the main beam tube 111. Specifically, since the main wire harness 151 has a long length and high strength and is not easily bent, the present application designs a main beam tube 111 that extends basically along the length direction of the vehicle frame 11, and fixes the main wire harness 151 to the main beam tube 111 through a plurality of fixing members. Through the above settings, the connection strength between the main wire harness 151 and the main beam tube 111 can be improved, which is beneficial to improving the connection stability of the main wire harness 151, and further beneficial to improving the structural stability of the motorcycle 100.

[0027] In this embodiment, the vehicle frame 11 further includes a first support pipe 112 and a second support pipe 113. Along the width direction of the vehicle frame 11, the first support pipe 112 and the second support pipe 113 are respectively located on both sides of the longitudinal central plane 101. The engine 131 is connected to the first support pipe 112 and the second support pipe 113. Along the height direction of the vehicle frame 11, the main beam pipe 111 at least partially overlaps with the first support pipe 112. Specifically, the first support pipe 112 and the second support pipe 113 are respectively located on both sides of the longitudinal central plane 101, and the first support pipe 112 and the second support pipe 113 are asymmetrically arranged with respect to the longitudinal central plane 101. Among them, the length and mass of the second support pipe 113 are higher than those of the first support pipe 112, that is, the strength of the first support pipe 112 is lower than that of the second support pipe 113. Therefore, in this application, the first support pipe 112 and the main beam pipe 111 are arranged on the same side of the longitudinal central plane 101, so that the first support pipe 112 and the main beam pipe 111 balance the mass of the second support pipe 113, which is beneficial to improving the body stability of the motorcycle 100. At the same time, the structure of the main beam pipe 111 and the first support pipe 112 is compact, which is further beneficial to improving the space utilization rate of the motorcycle 100.

[0028] Exemplarily, along the width direction of the vehicle frame 11, the maximum distance between the first support pipe 112 and the longitudinal central plane 101 is defined as the first distance D1, and the maximum distance between the second support pipe 113 and the longitudinal central plane 101 is defined as the second distance D2. The ratio range of the first distance D1 to the second distance D2 is 0.7 to 0.9. Specifically, the ratio range of the first distance D1 to the second distance D2 is 0.75 to 0.85. More specifically, the ratio of the first distance D1 to the second distance D2 is 0.8. Through the above settings, it is possible to avoid the width of the engine 131 on one side of the longitudinal central plane 101 being too large due to the ratio range of the first distance D1 to the second distance D2 being too large, so as to prevent the body width of the motorcycle 100 from being too large, which is beneficial to improving the structural compactness of the motorcycle 100; and it is also possible to avoid the distance between the center of gravity of the engine 131 and the longitudinal central plane 101 being too far due to the ratio range of the first distance D1 to the second distance D2 being too small, so as to prevent the main wire harness 151 from being unable to balance the center of gravity of the engine 131, which is beneficial to improving the body stability of the motorcycle 100.

[0029] Such as Figure 1 and Figure 2As shown, as an implementation, the motorcycle 100 further includes a carbon canister 16 and a fuel tank 17. The carbon canister 16 is connected to the main beam tube 111, and the carbon canister 16 communicates with the fuel tank 17. Along the length direction of the frame 11, the carbon canister 16 is basically located behind the engine 131. Along the height direction of the frame 11, the fuel tank 17 is basically located above the engine 131. Along the height direction of the frame 11, the carbon canister 16 is basically located below the main wire harness 151. Specifically, along the length direction of the frame 11, the carbon canister 16 at least partially overlaps with the engine 131; along the height direction of the frame 11, the fuel tank 17 at least partially overlaps with the engine 131; along the height direction of the frame 11, the carbon canister 16 at least partially overlaps with the main wire harness 151. Among them, the carbon canister 16 is used to adsorb the oil and gas of the fuel tank 17 and transport the processed oil and gas to the engine 131. Through the above settings, the layout of the carbon canister 16, the main wire harness 151, the engine 131 and the fuel tank 17 can be made more reasonable, which is beneficial to improving the layout rationality of the motorcycle 100. Moreover, the carbon canister 16 and the main wire harness 151 are basically on the same side of the longitudinal center plane 101 to balance the center of gravity of the engine 131, which is further beneficial to improving the body stability of the motorcycle 100.

[0030] As Figure 5 shown, as an implementation, the motorcycle 100 further includes a brake assembly 18. A storage space 102 is formed between the transmission assembly 14, the frame 11 and the engine 131. Both the brake assembly 18 and the carbon canister 16 are located in the storage space 102. Specifically, the brake assembly 18 is used to brake the traveling assembly 12. Concentrating the carbon canister 16 and the brake assembly 18 can make the structures of the carbon canister 16 and the brake assembly 18 more compact, which is beneficial to improving the structural compactness of the carbon canister 16 and the brake assembly 18, and further improving the space utilization rate of the motorcycle 100.

[0031] As Figure 2As shown, in this embodiment, along the length direction of the frame 11, the minimum distance D3 between the carbon canister 16 and the engine 131 ranges from 15 cm to 25 cm. Further, along the length direction of the frame 11, the minimum distance D3 between the carbon canister 16 and the engine 131 ranges from 17 cm to 23 cm. Still further, along the length direction of the frame 11, the minimum distance range D3 between the carbon canister 16 and the engine 131 is from 19 cm to 21 cm. Through the above settings, it is possible to avoid the distance between the carbon canister 16 and the engine 131 being too far due to the excessive minimum distance D3 range between the carbon canister 16 and the engine 131, so as to prevent the gas transmission distance of the carbon canister 16 to the engine 131 from being too large, thereby facilitating the improvement of the working efficiency of the carbon canister 16 and the engine 131; and it is also possible to avoid the distance between the carbon canister 16 and the engine 131 being too close due to the too small minimum distance D3 range between the carbon canister 16 and the engine 131, so as to prevent the heat of the engine 131 from being transferred to the carbon canister 16, and further facilitating the improvement of the service life of the carbon canister 16.

[0032] As an implementation manner, the motorcycle 100 further includes an exhaust assembly 19. The exhaust assembly 19 at least partially surrounds the engine 131 and is in communication with the engine 131. The engine 131 includes an oil pan 1311. The oil pan 1311 and the exhaust assembly 19 are respectively located on both sides of the longitudinal central plane 101. Specifically, a large amount of engine oil is stored in the oil pan 1311, and the exhaust assembly 19 is basically made of metal and has a large volume. Therefore, in this application, by respectively locating the oil pan 1311 and the exhaust assembly 19 on both sides of the longitudinal central plane 101, the center of gravity of the oil pan 1311 and the center of gravity of the exhaust assembly 19 are balanced with each other, thereby facilitating the improvement of the body stability of the motorcycle 100.

[0033] In this embodiment, along the width direction of the frame 11, the oil pan 1311 and the main wire harness 151 are located on the same side of the longitudinal central plane 101. Specifically, since the quality of the engine oil in the oil pan 1311 is relatively high, the center of gravity of the engine 131 can be balanced by the oil pan 1311 and the main wire harness 151 together, thereby facilitating the center of gravity of the motorcycle 100 to be on the longitudinal central plane 101, and further facilitating the improvement of the driving safety of the motorcycle 100.
