[0030] In order to enable those skilled in the art 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.

[0031] FIG1 shows a motorcycle 100, which includes a frame 11, a running system 12, a powertrain 13, a power battery 14, and a suspension system 15. The frame 11 forms the basic framework of the motorcycle 100 and is used to support the running system 12, the powertrain 13, the power battery 14, and the suspension system 15. The running system 12 includes a front wheel 121 and a rear wheel 122. The powertrain 13 is transmission-connected to at least one of the front wheel 121 and the rear wheel 122, thereby enabling the front wheel 121 and the rear wheel 122 to achieve movement of the motorcycle 100. The powertrain 13 and the power battery 14 are both at least partially disposed on the frame 11. The power battery 14 is electrically connected to the powertrain 13 and is used to provide energy to the powertrain 13. The suspension system 15 is connected to the frame 11, and the front wheel 121 and the rear wheel 122 are both connected to the frame via the suspension system 15. To clearly illustrate the technical solution of this application, the terms front, rear, left, right, up, and down are also defined as shown in Figure 1. It should be understood that in this embodiment, the front-to-back direction refers to the length of the motorcycle 100, the left-to-right direction refers to the width of the motorcycle 100, and the up-to-down direction refers to the height of the motorcycle 100. It should be understood that, along the up-to-down direction of the motorcycle 100, the traveling system 12 is at least partially disposed below the frame 11.

[0032] As shown in Figures 2 and 3, the frame 11 includes a main frame 111 and a front bracket 112. The front bracket 112 is located at the front side of the main frame 111 and is fixedly connected to the main frame 111. Specifically, the main frame 111 includes an upper support frame 1111, a front mounting frame 1112, a rear mounting frame 1113, and a lower support frame 1114. When viewed across the width of the motorcycle 100, the upper support frame 1111 generally has a tripod structure and is located substantially at the top of the frame 11. Therefore, the upper support frame 1111 generally constitutes the primary support portion of the motorcycle 100's beam frame. The lower support frame 1114 includes a plurality of pipes extending in the front-to-back direction. These pipes are distributed substantially along the width of the frame 11 and are respectively connected to one or more pipes extending in the width direction. The lower support frame 1114 is located substantially at the bottom of the frame 11. Therefore, the lower support frame 1114 generally constitutes the primary support portion of the motorcycle 100's chassis. Front mounting frame 1112 is generally located at the front side of vehicle frame 11. Front mounting frame 1111 includes several pipes extending generally in the vertical direction, and several pipes are generally distributed along the width direction. The upper side of front mounting frame 1112 is fixedly connected to the front side of upper support frame 1111, and the lower side of front mounting frame 1112 is integrally formed with the front side of lower support frame 1114. Rear mounting frame 1113 is located at the rear side of front mounting frame 1112. Rear mounting frame 1113 includes several pipes extending generally in the vertical direction, and several pipes are generally distributed along the width direction. The upper side of rear mounting frame 1113 is fixedly connected to the rear side of upper support frame 1111, and the lower side of rear mounting frame 1113 is fixedly connected to the rear side of lower support frame 1114. Through the above-mentioned arrangement, the upper support frame 1111, the front mounting frame 1112, the rear mounting frame 1113, and the lower support frame 1114 are interconnected to form a stable whole. This arrangement can achieve lightweighting of the entire vehicle and maximize the installation space while ensuring the strength of the main frame 111. It should be noted that the upper support frame 1111, the front mounting frame 1112, the rear mounting frame 1113, and the lower support frame 1114 are interconnected to form a main accommodating space 101, that is, the main frame 111 is formed around the main accommodating space 101. The main frame 111 is used to support body parts, and the main accommodating space 101 is used to accommodate body parts. In the present application, the powertrain 13 and the power battery 14 are both connected to the main frame 111 and are at least partially located in the main accommodating space 101.

[0033] As shown in FIG2 , as one implementation, the suspension system 15 includes a front suspension 151 connected to a front bracket 112 and located in front of the main frame 111. The powertrain 13 includes a drive motor 131. The drive motor 131 and the power battery 14 are both located behind the front suspension 151 and connected to the main frame 111. Specifically, the front side of the power battery 14 is connected to the front mounting frame 1112, the rear side of the power battery 14 is connected to the rear mounting frame 1113, the upper side of the power battery 14 is connected to the upper support frame 1111, and the lower side of the power battery 14 is connected to the lower support frame 1114. The power battery 14 includes a battery opening 141, and the drive motor 131 is located within the battery opening 141. The drive motor 131 is at least partially connected to the main frame 111 and is transmission-connected to at least one of the front wheel 121 and the rear wheel 122, so that the drive motor 131 can provide kinetic energy to the front wheel 121 and / or the rear wheel 122. More specifically, the drive motor 131 is located within the main accommodating space 101, and the power battery 14 is at least partially disposed around the drive motor 131 and is electrically connected to the drive motor 131, so that the power battery 14 can provide electrical energy to the drive motor 131. Through this arrangement, the electrical energy of the power battery 14 is converted into kinetic energy for the drive motor 131, which is then transferred to the front wheel 121 and / or the rear wheel 122, thereby enabling the movement of the motorcycle 100. More specifically, when viewed from the height of the motorcycle 100, the power battery 14 and the drive motor 131 at least partially overlap. When viewed from the length of the motorcycle 100, the power battery 14 and the drive motor 131 at least partially overlap. This arrangement allows both the power battery 14 and the drive motor 131 to be located within the main storage space 101, maintaining a compact structure without interfering with each other. This facilitates the compactness of the power battery 14 and the drive motor 131, and consequently, the compactness of the motorcycle 100. Furthermore, the center of gravity of the power battery 14 and the drive motor 131 is concentrated and substantially located at the horizontal center of the motorcycle 100, thereby enhancing the stability of the motorcycle 100. In addition, the drive motor 131 is disposed in the battery opening 141 and connected to the main frame 111 , so that the power battery 14 can protect the drive motor 131 , thereby facilitating improving the service life of the drive motor 131 .

[0034] As an implementation method, a longitudinal plane 102 perpendicular to the width of the motorcycle 100 is defined. The longitudinal plane 102 substantially bisects the motorcycle 100, i.e., the motorcycle 100 is substantially symmetrical about the longitudinal plane 102. The projected area of ​​the main accommodating space 101 along the width of the motorcycle 100 on the longitudinal plane 102 is set as a first projected surface, and the sum of the projected areas of the drive motor 131 and the power battery 14 along the width of the motorcycle 100 on the longitudinal plane 102 is set as a second projected surface. The ratio of the first projected surface to the second projected surface is greater than or equal to 1.02 and less than or equal to 1.48. Specifically, the ratio of the first projected surface to the second projected surface is greater than or equal to 1.12 and less than or equal to 1.35. More specifically, the ratio of the first projected surface to the second projected surface is 1.23. Through the above-mentioned setting, it is possible to avoid the drive motor 131 and the power battery 14 occupying too small a proportion of the main accommodation space 101 due to the ratio of the first projection surface to the second projection surface being too large, thereby preventing excessive waste of the main accommodation space 101, thereby helping to improve the space utilization rate of the main frame 111; it is also possible to avoid the drive motor 131 and the power battery 14 occupying a larger main accommodation space 101 due to the ratio of the first projection surface to the second projection surface being too small, thereby preventing interference between the drive motor 131 and the power battery 14, thereby helping to improve the rationality of the layout of the power battery 14 and the drive motor 131.

[0035] In one implementation, the power battery 14 includes a first battery body 142 that extends at least partially along the length of the motorcycle 100, and a second battery body 143 that extends at least partially along the height of the motorcycle 100. The first and second battery bodies 142, 143 are disposed at least partially around the drive motor 131. In this embodiment, the first and second battery bodies 142, 143 are at least partially connected to form a battery opening 141. This means that the first and second battery bodies 142, 143 can be fixedly connected or integrally arranged, thereby improving the structural strength of the power battery 14. Specifically, when the first battery body 142 is located above the second battery body 143, the drive motor 131 is located in front of or behind the second battery body 143. As another alternative, when the first battery body 142 is located below the second battery body 143, the drive motor 131 is located in front of or behind the second battery body 143. It should be noted that the first battery body 142 and the second battery body 143 can be configured according to actual needs to ensure a stable connection between the power battery 14 and the main frame 111 .

[0036] As an implementation, the powertrain 13 further includes a motor controller 132. The motor controller 132 and the drive motor 131 are distributed along the height of the motorcycle 100, with the motor controller 132 disposed between the first battery body 142 and the drive motor 131. Specifically, the motor controller 132 is located within the battery opening 141 and is detachably connected to the drive motor 131 via fasteners. This arrangement allows the drive motor 131 and the power battery 14 to be disposed around the motor controller 132, thereby facilitating protection of the motor controller 132. Furthermore, the motor controller 132 is disposed close to the power battery 14 to facilitate electrical connection between the motor controller 132 and the power battery 14, thereby facilitating improved structural compactness of the powertrain 13.

[0037] As an implementation, the projection of the axis of the drive motor 131 along the width of the motorcycle 100 onto the longitudinal plane 102 is a first projection point. The axis of the drive motor 131 refers to the axis of the output shaft of the drive motor 131. The projection of the center of gravity of the motor controller 132 along the width of the motorcycle 100 onto the longitudinal plane 102 is a second projection point. Since the motor controller 132 is essentially a rectangular parallelepiped, the center of gravity of the motor controller 132 refers to the geometric center of the rectangular parallelepiped. The projection of the axis of the rear wheel 122 along the width of the motorcycle 100 onto the longitudinal plane 102 is a third projection point. The line connecting the first and third projection points is a first line L1, and the line connecting the second and third projection points is a second line L2. The ratio of the first line L1 to the second line L2 is set to be greater than or equal to 0.69 and less than or equal to 0.98. Specifically, the ratio of the first line L1 to the second line L2 is set to be greater than or equal to 0.76 and less than or equal to 0.91. More specifically, the ratio of the first line L1 to the second line L2 is set to 0.87. This configuration prevents the drive motor 131 from being positioned too far forward due to an excessively large ratio of the first line L1 to the second line L2, thereby preventing an imbalance in the center of gravity of the motorcycle 100 and improving the stability of the motorcycle 100. It also prevents the motor controller 132 from occupying a larger portion of the main accommodation space 101 due to an excessively small ratio of the first line L1 to the second line L2, thereby preventing the motor controller 132 from interfering with the layout of the power battery 14, thereby improving the layout rationality and space utilization of the motorcycle 100.

[0038] As an implementation, the powertrain 13 further includes a reducer 133, which is located within the battery opening 141. The reducer 133 is fixedly connected to the drive motor 131, and the drive motor 131, motor controller 132, and reducer 133 are integrated. Specifically, the drive motor 131, motor controller 132, and reducer 133 can be fixedly connected to form an integrated structure. This arrangement allows the drive motor 131, motor controller 132, and reducer 133 to be compact and stably connected, thereby improving the structural compactness and connection stability of the powertrain 13, facilitating assembly of the powertrain 13 with the main frame 111, and thereby improving the assembly performance of the motorcycle 100.

[0039] In this embodiment, there is a gap 1411 between the battery opening 141 and the drive motor 131, and the width D1 of the gap 1411 is set to be greater than or equal to 1.2 mm and less than or equal to 3.6 mm. Specifically, the width D1 of the gap 1411 is set to be greater than or equal to 1.6 mm and less than or equal to 2.9 mm. More specifically, the width D1 of the gap 1411 is set to 2.4 mm. Through the above setting, it is possible to avoid wasting the main accommodating space 101 due to the excessive width D1 of the gap 1411, thereby facilitating the improvement of the space utilization rate of the motorcycle 100; it is also possible to avoid the heat dissipation of the drive motor 131 due to the excessively small width D1 of the gap 1411, thereby facilitating the improvement of the heat dissipation of the drive motor 131, and the power battery 14 is not heat-resistant, and at the same time, it is beneficial to improve the service life of the power battery 14.

[0040] As an implementation, the suspension system 15 further includes a swingarm 152, with a mounting point 1113a provided on the rear mounting frame 1113. The swingarm 152 is used to connect the rear mounting frame 1113 and the rear wheel 122. Fasteners are provided through the drive motor 131, the swingarm 152, and the mounting point 1113a, rotatably connecting the swingarm 152 to the main frame 111 and fixedly connecting the drive motor 131 to the rear mounting frame 1113. Specifically, one end of the swingarm 152 is rotatably connected to the rear mounting frame 1113, the other end of the swingarm 152 is connected to the rear wheel 122, the rear side of the drive motor 131 is fixedly connected to the rear mounting frame 1113, and the swingarm 152 is at least partially disposed on the rear side of the rear mounting frame 1113. Through the above arrangement, the rear swing arm 152 and the drive motor 131 can both be connected to the mounting point 1113a, thereby reducing the number of mounting points 1113a arranged on the frame 11, thereby facilitating the improvement of the assembly performance of the main frame 111, the drive motor 131 and the rear swing arm 152, while reducing the number of fasteners used, thereby further facilitating the improvement of the space utilization of the motorcycle 100.

[0041] As shown in Figures 2 and 3, as an implementation method, a motor mounting portion 1114a is provided on the front side of the lower support frame 1114, a motor connecting frame 113 is provided on the rear side of the lower support frame 1114, and a first connecting portion 1311 and a second connecting portion 1312 are provided on the lower side of the drive motor 131. The motor mounting portion 1114a is connected to the first connecting portion 1311, and the motor connecting frame 113 is connected to the second connecting portion 1312, so as to connect the drive motor 131 to the lower support frame 1114. Through the above arrangement, the drive motor 131 can be stably connected to the lower support frame 1114, thereby facilitating improved connection stability between the drive motor 131 and the lower support frame 1114, and further facilitating improved structural stability of the motorcycle 100.

[0042] As shown in FIG3 , as one implementation, the power battery 14 includes a battery housing 144 and several connecting portions 1441 disposed on the battery housing 144. The connecting portions 1441 extend toward the vehicle frame 11. The battery housing 144 and the connecting portions 1441 may be integrally formed or fixedly connected. A connecting member 1115 corresponding to the connecting portion 1441 is disposed on the main frame 111. The connecting member 1115 extends from the vehicle frame 11 toward the main accommodating space 101. The connecting portions 1441 are fixedly connected to the connecting member 1115, thereby securely connecting the power battery 14 to the vehicle frame 11. A gap is formed between the power battery 14 and the vehicle frame 11, and the connecting member 1115 at least partially overlaps the main accommodating space 101 along the width of the motorcycle 100. The main frame 111 and the connecting member 1115 may be integrally formed or fixedly connected. Specifically, when viewed across the width of the motorcycle 100, the connection portion 1441 is substantially disposed around the exterior of the battery housing 144, and the connector 1115 is substantially disposed around the interior of the main frame 111. This arrangement enables a fixed connection between the power battery 14 and the main frame 111 via the connection portion 1441 and the connector 1115, thereby simplifying the connection between the power battery 14 and the main frame 111 and facilitating their installation, thereby improving their assembly. Furthermore, a certain gap is left between the power battery 14 and the main frame 111, facilitating the placement of components such as wiring harnesses, thereby improving the space utilization of the motorcycle 100.

[0043] As shown in Figures 4 and 5, as an implementation method, the suspension system 15 includes a shock absorber 153 connecting the rear swing arm 152 and the frame 11. The rear swing arm 152 is used to connect the rear wheel 122, and the shock absorber 153 is used to buffer the interaction force between the frame 11 and the rear swing arm 152.

[0044] As an implementation, the suspension system 15 includes a linkage mechanism 153, through which the frame 11 and the rear swing arm 152 are rotatably connected, and the rear swing arm 152 and the shock absorber 153 are rotatably connected. Specifically, a motor connecting frame 113 and a connecting rod connecting frame 114 are fixedly connected or integrally formed on the frame 11. The drive motor 131 is connected to the motor connecting frame 113, and the connecting rod mechanism 153 is connected to the connecting rod connecting frame 114. Through this arrangement, the drive motor 131 and the connecting rod mechanism 153 are interconnected via the motor connecting frame 113 and the connecting rod connecting frame 114, thereby improving the connection strength between the drive motor 131 and the connecting rod connecting frame 114 and the frame 11. The structure of the motor connecting frame 113 and the connecting rod connecting frame 114 is also more compact, thereby facilitating improved structural compactness of the drive motor 131 and the connecting rod mechanism 153, and also facilitating improved space utilization of the motorcycle 100.

[0045] As shown in Figure 6, the motorcycle 100 includes an electrical system 17, which is at least partially arranged on the frame 11. The electrical system 17 is electrically connected to the power battery 14 and the electrical equipment. The suspension system 15 also includes a front suspension 151 arranged on the front side of the motorcycle 100, and the front suspension 151 connects the front wheel 121 to the frame 11. Specifically, the electrical system 17 includes a DC conversion structure 171, which is used to change the voltage output by the power battery 14. Among them, the DC conversion structure 171 can be set as a DC-DC (DC-DC, DC-to-DC converter) conversion structure.

[0046] As an implementation method, a longitudinal plane 102 perpendicular to the width of the motorcycle 100 is defined. The front surface of the power battery 14 extends substantially along the predetermined plane 104. The projection of the predetermined plane 104 along the width of the motorcycle 100 onto the longitudinal plane 102 is a first projection line. The front suspension 151 extends substantially along a predetermined straight line 105. The front side surface of the front suspension 151 is located on the predetermined straight line 105. The projection of the predetermined straight line 105 along the width of the motorcycle 100 onto the longitudinal plane 102 is a second projection line. The projection of the DC converter structure 171 along the width of the motorcycle 100 onto the longitudinal plane 102 is a projection surface. The projection surface is at least partially located between the first projection line and the second projection line. With this arrangement, the DC converter structure 171 can be arranged between the first projection line and the second projection line, thereby improving space utilization of the motorcycle 100 and facilitating assembly and disassembly of the DC converter structure 171, thereby enhancing assembly and maintenance performance of the DC converter structure 171.

[0047] As shown in FIG7 , as one implementation, a DC conversion structure 171 can be positioned near a predetermined plane 104 and fixedly connected to the vehicle frame 11. The main frame 111 includes a first bracket 1112a and a second bracket 1112b. The first bracket 1112a and the second bracket 1112b are positioned substantially in front of the power battery 14 and are substantially symmetrical about the longitudinal plane 102. The DC conversion structure 171 is positioned between the first bracket 1112a and the second bracket 1112b. This arrangement effectively utilizes the space between the first bracket 1112a and the second bracket 1112b, thereby improving the space utilization of the motorcycle 100. Furthermore, by being fixedly connected to the first and second brackets 1112b, the connection strength of the DC conversion structure 171 is increased, thereby improving the connection stability of the DC conversion structure 171.

[0048] As shown in Figures 8 and 9, as an implementation method, the frame 11 also includes a motor bracket 115. The main frame 111 includes a plurality of mounting brackets distributed along the length direction of the motorcycle 100 and a plurality of longitudinal frames distributed along the height direction of the motorcycle 100. The motor bracket 115 connects at least one mounting bracket and at least one longitudinal frame. It should be noted that the upper support frame 1111 and the lower support frame 1114 are both longitudinal frames. Similarly, the front mounting frame 1112 and the rear mounting frame 1113 are both mounting brackets. Through the above arrangement, the motor bracket 115 can be selectively connected as needed to ensure that the motor bracket 115 is connected to the main frame 111 and the drive motor 131 respectively. In this embodiment, the motor bracket 115 is connected to the rear mounting frame 1113 and the lower support frame 1114 as an example for explanation.

[0049] In this embodiment, the motor bracket 115 includes at least two mounting portions 1151 connected to the main frame 111. The motor bracket 115 also includes a connecting portion 1152 connected to the drive motor 131. The connecting portion 1152 is disposed between any two mounting portions 1151. The connecting portion 1152 is at least partially disposed within the main accommodating space 101 and is connected to the drive motor 131. Specifically, in the left-right direction of the motorcycle 100, the motor bracket 115 is at least partially disposed on the left and / or right side of the drive motor 131. The drive motor 131 can be connected to the main frame 111 via the motor bracket 115. This arrangement helps improve the connection stability between the drive motor 131 and the main frame 111. Furthermore, when viewed across the width of the motorcycle 100, the motor bracket 115 and the drive motor 131 at least partially overlap, thereby improving the compactness of the drive motor 131 and the motor bracket 115, and also improving the space utilization of the motorcycle 100.

[0050] As an implementation, the main frame 111 includes a rear mounting frame 1113 extending along the height direction of the motorcycle 100 and a lower support frame 1114 extending along the length direction of the motorcycle 100. The rear mounting frame 1113 is provided with a bracket mounting portion 1113b, and the lower support frame 1114 is provided with a motor mounting portion 1114a (see Figure 3). The mounting portion 1151 includes a first mounting portion 1151a and a second mounting portion 1151b. The first mounting portion 1151a is connected to the bracket mounting portion 1113b, and the second mounting portion 1151b is connected to the motor mounting portion 1114a, so that the motor bracket 115 is respectively connected to the lower support frame 1114 and the rear mounting frame 1113. This arrangement can improve the connection strength between the motor bracket 115 and the main frame 111, thereby facilitating the improvement of the connection stability between the drive motor 131 and the frame 11, and further facilitating the improvement of the structural stability of the motorcycle 100. It should be noted that the drive motor 131 is detachably connected to the motor bracket 1114a using fasteners. Therefore, the second mounting portion 1151b and the drive motor 131 can be connected to the motor mounting portion 1114a using a single fastener. This reduces the number of connection points on the motor mounting portion 1114a, thereby improving the assembly performance of the second mounting portion 1151b and the drive motor 131. Furthermore, the connection strength between the second mounting portion 1151b, the drive motor 131, and the motor mounting portion 1114a can be increased, thereby improving the structural stability of the motorcycle 100.

[0051] As an implementation, the motor bracket 115 includes a first support bracket 1153 extending generally in the front-to-rear direction of the motorcycle 100, and a second support bracket 1154 extending generally in the upper-lower direction of the motorcycle 100. The first support bracket 1153 is fixedly connected to the second support bracket 1154. A first mounting portion 1151a is disposed on the first support bracket 1153, and a second mounting portion 1151b is disposed on the second support bracket 1154, so that the first support bracket 1153 is connected to the rear mounting bracket 1113, and the second support bracket 1154 is connected to the lower support bracket 1114. Specifically, when viewed along the width of the motorcycle 100, the first support bracket 1153 and the second support bracket 1154 are arranged at a substantially right angle, thereby facilitating improved structural stability and compactness of the first support bracket 1153 and the second support bracket 1154, thereby facilitating improved structural strength and compactness of the motor bracket 115.

[0052] As an implementation, the motor bracket 115 further includes a bracket tube 1155 extending at least partially toward the drive motor 131. The bracket tube 1155 is connected to the drive motor 131 and extends substantially along the width of the motorcycle 100. Specifically, the bracket tube 1155 is connected to a portion of the drive motor 131 that is away from the main frame 111, so that the drive motor 131 can be stably connected to the main frame 111 via the bracket tube 1155. A circular through-hole 1155a is defined within the bracket tube 1155, and a motor through-hole 1314 (see FIG. 5 ) corresponding to the circular through-hole 1155a is defined in the drive motor 131. Fasteners penetrate the motor through-hole 1314 and the circular through-hole 1155a to securely connect the drive motor 131 to the bracket tube 1155. Through the above arrangement, bracket tube 1155 can be removed from and installed on the drive motor 131 and main frame 111 as needed, thereby improving the assembly efficiency of motor bracket 115, drive motor 131, and main frame 111. Furthermore, bracket tube 1155 is relatively strong, and the fasteners can be relatively strong bolts, thereby improving the connection strength between drive motor 131 and motor bracket 115, thereby further improving the structural stability of motorcycle 100.

[0053] In this embodiment, the extension direction of the bracket tube 1155 is substantially perpendicular to the first support frame 1153 and the second support frame 1154. A motor accommodating space 135 is formed between the first support frame 1153, the second support frame 1154, the bracket tube 1155, the rear mounting frame 1113, and the lower support frame 1114. The drive motor 131 is at least partially located within the motor accommodating space 135. With this arrangement, the drive motor 131 occupies a larger portion of the motor accommodating space 135, making the structure of the drive motor 131 and the motor bracket 115 more compact, thereby facilitating improved structural compactness of the drive motor 131 and the motor bracket 115.

[0054] As shown in Figures 10, 11, and 12, as one implementation, the motorcycle 100 includes a heat dissipation system 22. The heat dissipation system 22 is at least partially disposed on the frame 11 and includes a radiator 221. The radiator 221 has a gap for airflow. The heat dissipation system 22 is used to exchange heat with the powertrain 13 to reduce the temperature of the powertrain 13, allowing the powertrain 13 to operate normally. Specifically, the heat dissipation system 22 includes an air duct assembly 222. The air duct assembly 222 is at least partially disposed on the frame 11 and fixedly connected to the frame 11. The air duct assembly 222 is at least partially disposed on the underside of the saddle system 19 and is also at least partially disposed on the front side of the saddle system 19. The air duct assembly 222 further includes an air inlet structure 2221 and an air outlet structure 2223 that are interconnected. The air inlet structure 2221 and the air outlet structure 2223 are both configured as hollow cavity structures. The air intake structure 2221 is fixedly connected to the frame 11, and the air intake structure 2221 is located at the front side of the exhaust structure 2223 and is communicated with the outside world so that the air flow enters the air duct assembly 222. The exhaust structure 2223 is fixedly connected to the frame 11, and the exhaust structure 2223 is located at the rear side of the air intake structure 2221 and is communicated with the outside world. The exhaust structure 2223 can allow the air flow to be discharged from the air duct assembly 222. Along the length direction of the motorcycle 100, the radiator 221 is located between the air intake structure 2221 and the exhaust structure 2223. The air intake structure 2221 and the exhaust structure 2223 form a heat dissipation channel 2224, and the radiator 221 is at least partially located in the heat dissipation channel 2224. With the above arrangement, during operation of the motorcycle 100, cooler air flows through the air inlet structure 2221 toward the radiator 221. After completing heat exchange with the radiator 221, it is converted into a warmer airflow, which then flows out through the air outlet structure 2223. This reduces the temperature of the radiator 221, and consequently, the temperature of the powertrain 13, thereby achieving the heat dissipation function of the heat dissipation system 22. Furthermore, the separate design of the air inlet structure 2221 and the air outlet structure 2223 facilitates the arrangement and installation of the air duct assembly 222, thereby improving the installation efficiency and layout rationality of the motorcycle 100, and thus enhancing the assembly performance of the motorcycle 100.

[0055] As an optional implementation, the air duct assembly 222 further includes an air guide structure 2222, which is located on the lower side of the saddle system 19 and fixedly connected to the frame 11. The air guide structure 2222 is used to change the direction of the airflow within the air duct assembly 222. The air guide structure 2222 is located between the air inlet structure 2221 and the air exhaust structure 2223 and connects the air inlet structure 2221 and the air exhaust structure 2223. The air guide structure 2222 can also be configured as a hollow cavity structure, and the radiator 221 is at least partially located within the air guide structure 2222. Specifically, the heat dissipation channel 2224 further includes an air guide cavity 2224b, which is disposed within the air guide structure 2222 and connects the air inlet structure 2221 and the radiator 221. Through the above arrangement, the air guide structure 2222 can guide the airflow in the air inlet structure 2221 to the radiator 221, thereby facilitating heat exchange between the airflow and the radiator 221, thereby improving the cooling efficiency of the radiator 221 and the operating efficiency of the heat dissipation system 22. In addition, the air guide structure 2222 can be injection molded using an integrated molding process, thereby reducing the number of components of the air duct assembly 222 and the number of installation points of the air guide structure 2222, thereby simplifying the assembly process of the air duct assembly 222 and improving the installation efficiency of the air duct assembly 222.

[0056] In this embodiment, the air intake structure 2221 includes an air duct outer plate 2221c and an air duct inner plate 2221d, and the air duct outer plate 2221c and the air duct inner plate 2221d are fixedly connected. The heat dissipation channel 2224 also includes an air intake cavity 2224a, and the air intake cavity 2224a is formed by the air duct outer plate 2221c and the air duct inner plate 2221d. The air intake cavity 2224a basically extends along the front and rear directions of the motorcycle 100. The air intake structure 2221 includes an air intake end 2221e located at the front end of the air intake structure 2221 and a connection end 2221e located at the rear end of the air intake structure 2221. 21f, the air inlet cavity 2224a is located between the air inlet end 2221e and the connecting end 2221f, the air inlet end 2221e is arranged at the front side of the connecting end 2221f, the air inlet end 2221e is arranged as an opening connected to the outside world and faces the front of the motorcycle 100, the air inlet end 2221e is connected to the outside world so that the external airflow enters the air inlet cavity 2224a, the connecting end 2221f is arranged as an opening connected to the wind guide structure 2222, and the connecting end 2221f faces the rear of the motorcycle 100, so that the airflow can enter the wind guide structure 2222 from the air inlet structure 2221. Furthermore, the body cover 16 includes a rear fender 164 arranged on the rear side of the motorcycle 100, and the heat dissipation channel 2224 also includes an exhaust cavity 2224c, and the exhaust cavity 2224c is formed by the exhaust structure 2223 and the rear fender 164. The exhaust structure 2223 is provided with an exhaust end 2223c, and the exhaust end 2223c is arranged at the rear end of the exhaust structure 2223. The exhaust end 2223c is also set as an opening connected to the outside world and faces the left and right sides of the motorcycle 100. The exhaust cavity 2224c, the radiator 221 and the exhaust end 2223c are connected, and the exhaust end 2223c is also connected to the outside world. After passing through the radiator 221, the air flow flows to the exhaust cavity 2224c and is discharged through the exhaust end 2223c. Through the above setting, the air guide cavity 2224b is connected to the air inlet end 2221e and the air exhaust end 2223c, so that the air inlet cavity 2224a, the air guide cavity 2224b and the air exhaust cavity 2224c form a relatively closed heat dissipation channel 2224, thereby reducing the air volume loss and improving the heat dissipation effect of the radiator 221.

[0057] In this embodiment, an exhaust gap 192 is further provided between the saddle system 19 and the rear fender 164. The exhaust gap 192 is provided on the rear side of the saddle system 19. The exhaust gap 191 is connected to the exhaust cavity 2224c so that air can be discharged through the exhaust gap 192. Through the above arrangement, the exhaust gap 192 can improve the exhaust efficiency of the exhaust structure 2223, allowing the high-temperature airflow in the exhaust structure 2223 to be discharged as quickly as possible, thereby improving the heat dissipation efficiency of the heat dissipation system 22.

[0058] As shown in FIG13 , in this embodiment, since the wind speed inside the air intake structure 2221 is relatively high while the wind speed outside the air intake structure 2221 is relatively low during the air intake structure 2221 process, the air duct outer plate 2221c is subjected to pressure along the width direction of the motorcycle 100 due to the pressure difference between the inside and outside, resulting in the risk of deformation or damage to the air duct outer plate 2221c, thereby reducing the service life of the air duct outer plate 2221c. Therefore, reinforcement structures 2221g are provided on both sides of the air duct inner plate 2221d, and the reinforcement structures 2221g respectively abut against the air duct outer plate 2221c and the power battery 14. The reinforcement structures 2221g can be configured as reinforcing ribs, with the reinforcing ribs on one side abutting against the air duct outer plate 2221c and the reinforcing ribs on the other side abutting against the power battery 14. Through the above arrangement, the reinforcement structure 2221g can provide support for the air duct outer panel 2221c in the width direction of the motorcycle 100, thereby improving the structural strength of the air duct outer panel 2221c, preventing deformation or damage to the air duct outer panel 2221c, and thereby increasing the service life of the air duct outer panel 2221c. In addition, the reinforcement structure 2221g can also limit the position of the air duct outer panel 2221c, thereby facilitating the installation of the air duct outer panel 2221c.

[0059] In this embodiment, a transverse plane 108 perpendicular to the length of the motorcycle 100 is defined, and the area of ​​the projection of the air inlet end 2221e onto the transverse plane 108 along the length of the motorcycle 100 is larger than the area of ​​the projection of the connection end 2221f onto the transverse plane 108 along the length of the motorcycle 100. This arrangement results in a larger area of ​​the air inlet end 2221e, thereby increasing the flow rate of the airflow into the air inlet structure 2221 per unit time. The smaller area of ​​the connection end 2221f increases the velocity of the airflow from the air inlet structure 2221 to the air guide structure 2222, thereby increasing the velocity of the airflow from the air guide structure 2222 to the radiator 221. This, in turn, improves the efficiency of heat exchange between the airflow and the radiator 221, thereby enhancing the heat dissipation efficiency of the heat dissipation system 22.

[0060] It should be noted that, as shown in FIG14 , the air intake structure 2221 includes a first air intake structure 2221a and a second air intake structure 2221b distributed along the width of the motorcycle 100. The air exhaust structure 2223 includes a first air exhaust structure 2223a and a second air exhaust structure 2223b distributed along the width of the motorcycle 100. The first air intake structure 2221a and the second air intake structure 2221b are respectively connected to the air guide structure 2222, while the first air exhaust structure 2223a and the second air exhaust structure 2223b are respectively connected to the air guide structure 2222. A plane perpendicular to the width of the motorcycle 100 and passing through the center of the width of the motorcycle 100 is defined as the longitudinal plane 102 of the motorcycle 100. The first air intake structure 2221a and the second air intake structure 2221b are substantially symmetrical with respect to the longitudinal plane 102, and the first air exhaust structure 2223a and the second air exhaust structure 2223b are substantially symmetrical with respect to the longitudinal plane 102. Through the above-mentioned setting, the first air inlet structure 2221a and the second air inlet structure 2221b can increase the air intake volume of the air duct assembly 222; the first air exhaust structure 2223a and the second air exhaust structure 2223b can increase the air exhaust volume of the air duct assembly 222, thereby improving the heat dissipation effect of the radiator 221, and further improving the heat dissipation capacity of the heat dissipation system 22.

[0061] In this embodiment, the air inlet end 2221e and the air exhaust end 2223c are respectively provided with an air inlet grille 2221h and an exhaust grille 2223d. The air inlet grille 2221h can prevent foreign objects from entering the air inlet cavity 2224a and blocking the air duct assembly 222 during the air intake process. The exhaust grille 2223d can prevent foreign objects from entering the exhaust cavity 2224c and blocking the air duct assembly 222, so that the air duct assembly 222 is always in an unobstructed state, thereby improving the working stability of the air duct assembly 222.

[0062] As shown in FIG. 15 , as one implementation, along the front-to-back direction of the motorcycle 100, the radiator 221 is located between the air inlet end 2221e and the air outlet end 2223c. The radiator 221 is located below the saddle system 19 and is also at least partially disposed behind the power battery 14. The power assembly 13 is at least partially disposed below the power battery 14. The radiator 221 is also connected to the power assembly 13 via a cooling line 223, allowing coolant to circulate between the power assembly 13 and the radiator 221. This arrangement allows the radiator 221 to be located inside the motorcycle 100, thereby reducing dust adhesion to the radiator 221 and improving its heat dissipation and service life. It also facilitates disassembly, assembly, and maintenance of the radiator 221, improving its assembly and maintenance performance. In addition, the existing radiator 221 is usually provided with a cooling fan to dissipate heat from the radiator 221. The radiator 221 in the present application is at least partially provided in the air guide structure 2222 so that the radiator 221 can achieve heat dissipation of the radiator 221 by heat exchange with the air flow in the air duct assembly 222, thereby improving the heat dissipation efficiency of the radiator 221 and eliminating the need to provide a cooling fan, thereby reducing the weight of the motorcycle 100 and achieving lightweighting of the motorcycle 100.

[0063] In this embodiment, a reference plane 103 is defined perpendicular to the height direction of the motorcycle 100. The lowest end of the running system 12 is positioned on the reference plane 103. The minimum distance H3 between the radiator 221 and the reference plane 103 is greater than or equal to 680 mm and less than or equal to 770 mm. Specifically, the minimum distance H3 between the radiator 221 and the reference plane 103 can also be greater than or equal to 710 mm and less than or equal to 750 mm. In the present application, the minimum distance H3 between the radiator 221 and the reference plane 103 can be 735 mm. Through the above arrangement, it is possible to avoid the radiator 221 from being too low, which may cause damage to the radiator 221 due to collision caused by splashing sand and gravel during the driving of the motorcycle 100, or to avoid mud splashing and clogging the radiator 221, resulting in poor heat dissipation, thereby improving the service life of the radiator 221; it is also possible to avoid the radiator 221 from being too low, which may be detrimental to the arrangement of the air guide structure 2222 and the exhaust structure 2223, thereby improving the space utilization rate of the motorcycle 100; it is also possible to avoid the radiator 221 from being too high, which may interfere with the saddle system 19 and affect the arrangement of the saddle system 19, thereby allowing the saddle system 19 to cover the radiator 221, reducing dust adhesion on the surface of the radiator 221, and thereby improving the service life of the radiator 221.

[0064] In this embodiment, the projection of the front end of the radiator 221 onto the reference plane 103 along the height direction of the motorcycle 100 is a first projection line, the projection of the rear end of the radiator 221 onto the reference plane 103 along the height direction of the motorcycle 100 is a second projection line, the projection of the axis of the front wheel 121 onto the reference plane 103 along the height direction of the motorcycle 100 is a third projection line, and the projection of the axis of the rear wheel 122 onto the reference plane 103 along the height direction of the motorcycle 100 is a fourth projection line. The minimum distance between the first projection line and the third projection line along the length direction of the motorcycle 100 is a first distance D7, and the minimum distance between the second projection line and the fourth projection line along the length direction of the motorcycle 100 is a second distance D8. The ratio of the first distance D7 to the second distance D8 is greater than or equal to 2.1 and less than or equal to 2.6. Specifically, the ratio of the first distance D7 to the second distance D8 is greater than or equal to 2.2 and less than or equal to 2.5. In this embodiment of the present application, the ratio of the first distance D7 to the second distance D8 is 2.35. Through the above arrangement, it is possible to avoid the ratio of the first distance D7 to the second distance D8 being too large, thereby avoiding the radiator 221 being too close to the rear side of the motorcycle 100, causing interference between the radiator 221 and the rear fender 164 or the storage box 161, which is not conducive to the arrangement of the rear fender 164 or the storage box 161; and it is also possible to avoid the ratio of the first distance D7 to the second distance D8 being too small, thereby avoiding the radiator 221 being too close to the front side of the motorcycle 100, causing interference between the radiator 221 and the power battery 14, which is not conducive to the arrangement of the power battery 14. In this way, the radiator 221 can be located in a suitable arrangement position, avoiding interference with other components of the motorcycle 100, improving the rationality of the layout of the radiator 221, and facilitating the arrangement of the radiator 221 between the air guide structure 2222 and the exhaust structure 2223, thereby improving the heat dissipation effect of the radiator 221.

[0065] In one embodiment, a limiting plane 109 is defined perpendicular to the height of the motorcycle 100. The uppermost end of the powertrain 13 is located on the limiting plane 109, and the radiator 221 is at least partially located between the limiting plane 109 and the saddle system 19. This arrangement reduces the length of the cooling line 223 between the radiator 221 and the powertrain 13. This facilitates the layout of the cooling line 223 between the radiator 221 and the powertrain 13 while preventing interference with other components of the motorcycle 100, thereby improving the structural compactness of the motorcycle 100. In one embodiment, the frame 11 further includes a subframe 117. The main frame 111 and the subframe 117 are arranged substantially along the length of the motorcycle 100 and are fixedly connected. Specifically, a secondary accommodating space 1171 is formed around the subframe 117. The radiator 221 is located within the secondary accommodating space 1171 and is connected to the subframe 117. The suspension system 15 also includes a front suspension 151 connecting the frame 11 and the rear wheel 122, and a shock absorber 153 connecting the rear swingarm 152 and the frame 11. The radiator 221 is at least partially located behind the shock absorber 153. This arrangement not only improves the compactness of the motorcycle 100, but also prevents interference between the radiator 221 and the shock absorber 153 during movement of the motorcycle 100, thereby improving the service life and connection stability of the radiator 221.

[0066] As shown in FIG6 , as an implementation, the heat dissipation system 22 further includes a water pump structure 228 . The water pump structure 228 connects the radiator 221 and the power assembly 13 via a cooling line 223 . The cooling line 223 also connects the radiator 221 and the power assembly 13 , so that the radiator 221 , the power assembly 13 , and the water pump structure 228 form a loop through the cooling line 223 . This allows the coolant to carry heat and flow out of the power assembly 13 . Under the action of the water pump structure 228 , it flows to the radiator 221 for heat dissipation. After cooling, it flows back to the power assembly 13 , thereby achieving heat dissipation of the power assembly 13 by the heat dissipation system 22 . The water pump structure 228 can be configured as a combination of a brushless motor and an impeller. The brushless motor and the impeller are rotatably connected, and the brushless motor drives the impeller to rotate, causing the coolant to flow in the loop. Specifically, the water pump structure 228 is located behind the shock absorber 153, and at least partially in front of the rear fender 164. The water pump structure 228 is also at least partially disposed within the secondary accommodating space 1171. This arrangement not only reduces the length of the cooling line 223, thereby facilitating its layout and improving the compactness and space utilization of the motorcycle 100, but also facilitates disassembly and maintenance of the water pump structure 228, thereby improving the assembly and maintenance performance of the water pump structure 228. Furthermore, the location of the water pump structure 228 behind the shock absorber 153 and in front of the rear fender 164 prevents interference between the water pump structure 228 and the shock absorber 153 or the rear fender 164. The fact that the water pump structure 228 is at least partially disposed within the secondary accommodating space 1171 also allows the frame 11 to provide protection for the water pump structure 228.

[0067] In this embodiment, the water pump structure 228 is at least partially located on the rear side of the radiator 221. By placing the water pump structure 228 close to the radiator 221, the arrangement of the cooling pipe 223 can be reduced, thereby improving the compactness of the motorcycle 100 and further improving the space utilization of the motorcycle 100.

[0068] Furthermore, the minimum distance D3 between the water pump structure 228 and the shock absorber 153 is greater than or equal to 10 mm and less than or equal to 40 mm. Specifically, the minimum distance D3 between the water pump structure 228 and the shock absorber 153 is greater than or equal to 15 mm and less than or equal to 30 mm. In the embodiment of the present application, the minimum distance D3 between the water pump structure 228 and the shock absorber 153 is 20 mm. Through the above-mentioned arrangement, it is possible to avoid the distance between the water pump structure 228 and the shock absorber 153 being too large and occupying too much layout space, thereby improving the structural compactness of the water pump structure 228 and the shock absorber 153; it is also possible to avoid the distance between the water pump structure 228 and the shock absorber 153 being too large and interfering with the rear fender 164, thereby improving the space utilization rate of the motorcycle 100; it is also possible to avoid the distance between the water pump structure 228 and the shock absorber 153 being too small, resulting in the shock absorber 153 colliding with the water pump structure 228 during movement, thereby avoiding damage to the water pump structure 228, thereby improving the working life of the water pump structure 228.

[0069] In this embodiment, the water pump structure 228 is located above the limiting plane 109 and is also at least partially disposed below the radiator 221. This arrangement reduces the length of the cooling line 223 between the water pump structure 228 and the powertrain 13, as well as the length of the cooling line 223 between the water pump structure 228 and the radiator 221. This facilitates the layout of the cooling line 223 and improves the compactness of the motorcycle 100.

[0070] As shown in Figure 17, in this embodiment, the water pump structure 228 is fixedly connected to the subframe 11. Specifically, a mounting bracket 1173 is provided on the subframe 11, and the water pump structure 228 is fixedly connected to the subframe 11 via the mounting bracket 1173. This arrangement improves the connection strength of the water pump structure 228, preventing the water pump structure 228 from falling off due to vibration during the movement of the motorcycle 100, thereby improving the connection stability of the water pump structure 228.

[0071] Furthermore, the water pump structure 228 extends substantially along a predetermined straight line 204. Predetermined straight line 204 refers to the axis of the brushless motor or impeller in the water pump structure 228. When the water pump structure 228 is connected to the subframe 117, the predetermined straight line 204 extends substantially along the height of the motorcycle 100. In this configuration, the water pump structure 228 is in a longitudinal position. This arrangement reduces the space occupied by the water pump structure 228 in the longitudinal position and facilitates the layout of the cooling pipes 223, thereby improving the space utilization of the motorcycle 100.

[0072] As shown in FIG18 , as another implementation, the water pump structure 228 is fixedly connected to the rear fender 164 so that the rear fender 164 can provide support for the water pump structure 228, thereby reducing the number of parts in the motorcycle 100. Specifically, the rear fender 164 is provided with a receiving groove 1643, and the water pump structure 228 is at least partially disposed within the receiving groove 1643, so that the receiving groove 1643 can provide protection for the water pump structure 228. The motorcycle 100 is also provided with a fixing member 23 for fixing the water pump structure 228. The fixing member 23 abuts the water pump structure 228 and is also connected to the rear fender 164. The fixing member 23 and the receiving groove 1643 surround a fixed space, and the water pump structure 228 is at least partially disposed within the fixed space. Specifically, a through hole is provided on the rear fender 164. One end of the fixing member 23 at least partially extends through the through hole and is then engaged with the rear fender 164. The fastener at least partially extends through the other end of the fixing member 23 and is then fixedly connected to the rear fender 164. With this arrangement, a portion of the rear fender 164 serves as a load-bearing component for the water pump structure 228, eliminating the need for mounting structures on the vehicle frame 11. This reduces the number of mounting structures, simplifies the installation process of the water pump structure 228, and facilitates disassembly, assembly, and maintenance of the water pump structure 228, thereby improving the assembly and maintenance performance of the water pump structure 228.

[0073] It should be noted that when the water pump structure 228 is positioned within the receiving groove 1643, the predetermined straight line 204 extends substantially along the width of the motorcycle 100, and the water pump structure 228 is in a horizontal position. This arrangement increases the contact surface between the water pump structure 228 and the rear fender 164 when in the horizontal position, making the receiving groove 1643 larger. This improves the connection stability and operational stability of the water pump structure 228 within the receiving groove 1643.

[0074] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all such improvements and changes should fall within the scope of protection of the claims appended to this application.
