Description

Technical Field

[0001] The present invention relates to the technical field of vehicles, in particular to a motorcycle. Background Art

[0002] In the prior art, the radiator of a motorcycle is usually arranged on the outside of the motorcycle, and the heat is dissipated by heat exchange between the windward surface of the radiator and the natural air flow during the running of the motorcycle; or a cooling fan is arranged on the radiator to dissipate the heat of the radiator through the cooling fan. However, the radiator is arranged on the outside of the motorcycle, so that as the working time increases, the surface of the radiator will be covered with dust, which makes the heat dissipation effect of the radiator worse, resulting in higher engine operating temperature.

The ratio of the first distance to the second distance is greater than or equal to 2.1 and less than or equal to 2.6.

[0030] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the specific implementation manners of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the implementation manners of the present invention.

[0031] As Figure 1 and Figure 2A motorcycle 100 is shown. The motorcycle 100 includes a frame 11, a running system 12, a power assembly 13, a power battery 14, a suspension system 15, and a body covering 16. The frame 11 constitutes the basic framework of the motorcycle 100 and is used to support the running system 12, the power assembly 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 power assembly 13 is drivingly connected to at least one of the front wheel 121 and the rear wheel 122, so that the front wheel 121 and the rear wheel 122 can realize the movement of the motorcycle 100. Both the power assembly 13 and the power battery 14 are at least partially disposed on the frame 11. The power battery 14 and the power assembly 13 are electrically connected. The power battery 14 is used to provide energy for the power assembly 13. The suspension system 15 is connected to the frame 11, and both the front wheel 121 and the rear wheel 122 are connected to the frame 11 through the suspension system 15. The body covering 16 is at least partially disposed on the frame 11, and the body covering 16 is used to protect the internal parts of the motorcycle 100. To clearly illustrate the technical solution of the present application, the front, rear, left, right, up, and down as shown in Figure 1 are also defined. It can be understood that in the embodiments of the present application, the front-rear direction refers to the length direction of the motorcycle 100, the left-right direction refers to the width direction of the motorcycle 100, and the up-down direction refers to the height direction of the motorcycle 100. Specifically, the running system 12 is at least partially disposed below the frame 11.

[0032] Among them, as Figure 2As shown, the frame 11 includes a main frame 111 and a front bracket 112. The front bracket 112 is located on 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 observed in the width direction of the motorcycle 100, the upper support frame 1111 is substantially in a triangular frame structure and is substantially located at the uppermost part of the frame 11. Therefore, the upper support frame 1111 basically constitutes the main supporting part of the beam frame of the motorcycle 100. The lower support frame 1114 includes a plurality of pipe fittings extending in the front-rear direction, and the plurality of pipe fittings are substantially distributed in the width direction and are respectively connected to one or more pipe fittings extending in the width direction. The lower support frame 1114 is substantially located at the lowermost part of the frame 11. Therefore, the lower support frame 1114 basically constitutes the main supporting part of the chassis of the motorcycle 100. The front mounting frame 1112 is substantially located on the front side of the frame 11. The front mounting frame 1111 includes a plurality of pipe fittings extending substantially in the up-down direction, and the plurality of pipe fittings are substantially distributed in the width direction so that the upper side of the front mounting frame 1112 is fixedly connected to the front side of the upper support frame 1111, and the lower side of the front mounting frame 1112 is integrally formed with the front side of the lower support frame 1114. The rear mounting frame 1113 is located on the rear side of the front mounting frame 1112. The rear mounting frame 1113 includes a plurality of pipe fittings extending substantially in the up-down direction, and the plurality of pipe fittings are substantially distributed in the width direction. The upper side of the rear mounting frame 1113 is fixedly connected to the rear side of the upper support frame 1111, and the lower side of the rear mounting frame 1113 is fixedly connected to the rear side of the lower support frame 1114. Through the above settings, the upper support frame 1111, the front mounting frame 1112, the rear mounting frame 1113, and the lower support frame 1114 are connected to each other to form a stable whole. This setting method can achieve the light weight of the whole vehicle and the maximization of 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 connected to each other to form a main accommodation space 101, that is, the main frame 111 surrounds to form the main accommodation space 101. The main frame 111 is used to support the body parts, and the main accommodation space 101 is used to accommodate the body parts. In this application, the power assembly 13 and the power battery 14 are both connected to the main frame 111, and the power assembly 13 and the power battery 14 are both at least partially located in the main accommodation space 101.

[0033] As Figure 3 , Figure 4 and Figure 5As shown, as an 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. A gap for air flow is provided on the radiator 221. The heat dissipation system 22 is used for heat exchange with the power assembly 13 to reduce the temperature of the power assembly 13 so that the power assembly 13 can 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 lower side of the saddle system 19 and at least partially disposed on the front side of the saddle system 19. Further, the air duct assembly 222 includes an air inlet structure 2221 and an air outlet structure 2223 that communicate with each other. The air inlet structure 2221 is fixedly connected to the frame 11. The air inlet structure 2221 is located in front of the air outlet structure 2223 and communicates with the outside to allow air flow to enter the air duct assembly 222. The air outlet structure 2223 is fixedly connected to the frame 11. The air outlet structure 2223 is located behind the air inlet structure 2221 and communicates with the outside. The air outlet structure 2223 can allow air flow to exit the air duct assembly 222. Along the length direction of the motorcycle 100, the radiator 221 is located between the air inlet structure 2221 and the air outlet structure 2223. A heat dissipation channel 2224 is formed between the air inlet structure 2221 and the air outlet structure 2223. At least a part of the radiator 221 is located in the heat dissipation channel 2224. Through the above arrangement, during the running of the motorcycle 100, the relatively low-temperature air flow flows through the air inlet structure 2221 to the radiator 221, is converted into relatively high-temperature air flow after completing heat exchange with the radiator 221, and then flows out through the air outlet structure 2223, thereby reducing the temperature of the radiator 221, and further reducing the temperature of the power assembly 13, realizing the heat dissipation function of the heat dissipation system 22. In addition, the split design of the air inlet structure 2221 and the air outlet structure 2223 is beneficial to the arrangement and installation of the air duct assembly 222, thereby improving the installation efficiency and layout rationality of the motorcycle 100, and further improving the assembly performance of the motorcycle 100.

[0034] As an alternative implementation, the air duct assembly 222 further includes a wind guiding structure 2222. The wind guiding structure 2222 is located on the lower side of the saddle system 19 and is fixedly connected to the vehicle frame 11. The wind guiding structure 2222 is used to change the flow direction of the air flow inside the air duct assembly 222. The wind guiding structure 2222 is located between the air inlet structure 2221 and the air outlet structure 2223 and communicates with the air inlet structure 2221 and the air outlet structure 2223. At least a part of the radiator 221 is located inside the wind guiding structure 2222. Specifically, the heat dissipation channel 2224 further includes a wind guiding channel 2224b. The wind guiding channel 2224b is arranged inside the wind guiding structure 2222 and communicates with the air inlet structure 2221 and the radiator 221. Through the above arrangement, the wind guiding structure 2222 can guide the air flow in the air inlet structure 2221 to the radiator 221, so as to facilitate the heat exchange between the air flow and the radiator 221, and further improve the cooling efficiency of the radiator 221 and the working efficiency of the heat dissipation system 22. In addition, the wind guiding structure 2222 can be injection molded by an integral molding process, so that both the number of components of the air duct assembly 222 and the number of installation points of the wind guiding structure 2222 can be reduced, thereby simplifying the assembly process of the air duct assembly 222 and improving the installation efficiency of the air duct assembly 222.

[0035] In this embodiment, the air intake structure 2221 includes an outer air duct plate 2221c and an inner air duct plate 2221d. The outer air duct plate 2221c and the inner air duct plate 2221d are fixedly connected. The heat dissipation channel 2224 further includes an air intake channel 2224a, which is formed by surrounding the outer air duct plate 2221c and the inner air duct plate 2221d. The air intake structure 2221 further includes an air intake end 2221e and a connection end 2221f. The air intake channel 2224a is located between the air intake end 2221e and the connection end 2221f. The air intake end 2221e is arranged on the front side of the connection end 2221f. The air intake end 2221e is used to allow the external air flow to enter the air intake channel 2224a. The connection end 2221f is communicated with the air guiding structure 2222, so that the air flow can enter the air guiding structure 2222 from the air intake structure 2221. Further, the body covering 16 includes a rear mudguard 164 arranged at the rear side of the motorcycle 100. The heat dissipation channel 2224 further includes an exhaust air channel 2224c. The exhaust air structure 2223 and the rear mudguard 164 surround to form the exhaust air channel 2224c. The exhaust air structure 2223 further includes an exhaust air end 2223c, the exhaust air channel 2224c, the radiator 221 and the exhaust air end 2223c. The air flow flows to the exhaust air channel 2224c through the radiator 221 and is discharged through the exhaust air end 2223c. Through the above arrangement, the air guiding channel 2224b communicates the air intake end 2221e and the exhaust air end 2223c, so that the air intake channel 2224a, the air guiding channel 2224b and the exhaust air channel 2224c form a relatively airtight heat dissipation channel 2224, thereby reducing the air volume loss and improving the heat dissipation effect of the radiator 221.

[0036] In this embodiment, an exhaust air gap 192 is further provided between the saddle system 19 and the rear mudguard 164. The exhaust air gap 192 is arranged at the rear side of the saddle system 19. The exhaust air gap 191 is communicated with the exhaust air channel 2224c, so that the air flow can be discharged through the exhaust air gap 192. Through the above arrangement, the exhaust air gap 192 can improve the exhaust air efficiency of the exhaust air structure 2223, so that the high-temperature air flow in the exhaust air structure 2223 can be discharged as soon as possible, thereby improving the heat dissipation efficiency of the heat dissipation system 22.

[0037] Such as Figure 6As shown, in this embodiment, during the air intake process of the air duct outer plate 2221c in the air intake structure 2221, the air velocity inside the air intake structure 2221 is relatively high and the air velocity outside the air intake structure 2221 is relatively low. As a result, the air duct outer plate 2221c is subjected to a pressure in the width direction of the motorcycle 100 due to the internal and external pressure difference, leading to a risk of deformation or damage to the air duct outer plate 2221c, which will reduce the working life of the air duct outer plate 2221c. Therefore, strengthening structures 2221g are provided on both sides of the air duct inner plate 2221d, and the strengthening structures 2221g are respectively abutted against the air duct outer plate 2221c and the power battery 14. Among them, the strengthening structure 2221g can be set as a reinforcing rib. One side of the reinforcing rib is abutted against the air duct outer plate 2221c, and the other side of the reinforcing rib is abutted against the power battery 14. Through the above settings, the strengthening structure 2221g can provide a supporting force for the air duct outer plate 2221c in the width direction of the motorcycle 100, thereby improving the structural strength of the air duct outer plate 2221c, avoiding deformation or damage to the air duct outer plate 2221c, and further improving the working life of the air duct outer plate 2221c. In addition, the strengthening structure 2221g can also limit the air duct outer plate 2221c, thereby facilitating the installation of the air duct outer plate 2221c.

[0038] In this embodiment, a transverse plane 108 perpendicular to the length direction of the motorcycle 100 is defined. The area of the projection of the air intake end 2221e on the transverse plane 108 along the length direction of the motorcycle 100 is larger than the area of the projection of the connection end 2221f on the transverse plane 108 along the length direction of the motorcycle 100. Through the above settings, the area of the air intake end 2221e is larger, which can increase the flow rate of the air flowing into the air intake structure 2221 per unit time. The area of the connection end 2221f is smaller, which can increase the flow velocity of the air flowing from the air intake structure 2221 to the air guiding structure 2222, thereby increasing the flow velocity of the air flowing from the air guiding structure 2222 to the radiator 221, and further increasing the heat exchange efficiency between the air and the radiator 221, improving the heat dissipation efficiency of the heat dissipation system 22.

[0039] It should be noted that, as Figure 7As shown, the air intake structure 2221 includes a first air intake structure 2221a and a second air intake structure 2221b distributed in the width direction of the motorcycle 100. The air exhaust structure 2223 includes a first air exhaust structure 2223a and a second air exhaust structure 2223b distributed in the width direction of the motorcycle 100. The first air intake structure 2221a and the second air intake structure 2221b are respectively connected to the air guiding structure 2222, and the first air exhaust structure 2223a and the second air exhaust structure 2223b are respectively connected to the air guiding structure 2222. Define a plane perpendicular to the width direction of the motorcycle 100 and passing through the center of the width of the motorcycle 100 as the longitudinal plane 102 of the motorcycle 100. The first air intake structure 2221a and the second air intake structure 2221b are substantially symmetric about the longitudinal plane 102, and the first air exhaust structure 2223a and the second air exhaust structure 2223b are substantially symmetric about the longitudinal plane 102. Through the above settings, the first air intake structure 2221a and the second air intake 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 enhancing the heat dissipation capacity of the heat dissipation system 22.

[0040] In this embodiment, an air intake grille 2221h and an air exhaust grille 2223d are respectively provided at the air intake end 2221e and the air exhaust end 2223c. The air intake grille 2221h can prevent foreign objects from entering the air intake channel 2224a during the air intake process and blocking the air duct assembly 222, and the air exhaust grille 2223d can prevent foreign objects from entering the air exhaust channel 2224c and blocking the air duct assembly 222, so that the air duct assembly 222 can always be in an unobstructed state and the working stability of the air duct assembly 222 can be improved.

[0041] As Figure 8As shown, as an implementation, along the front-rear 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 on the lower side of the saddle system 19, and the radiator 221 is at least partially disposed at the rear side of the power battery 14. Among them, the powertrain 13 is at least partially disposed on the lower side of the power battery 14, and the radiator 221 is also connected to the powertrain 13 through the cooling pipeline 223, so that the coolant can circulate between the powertrain 13 and the radiator 221. Through the above settings, the radiator 221 can be located inside the motorcycle 100, which can not only reduce the adhesion of dust on the radiator 221, improve the heat dissipation effect and working life of the radiator 221, but also facilitate the disassembly, installation and maintenance of the radiator 221, and improve the assembly performance and maintenance performance of the radiator 221. In addition, the existing radiator 221 usually sets a cooling fan to dissipate heat from the radiator 221. In this application, at least part of the radiator 221 is disposed in the air guiding structure 2222, so that the radiator 221 can exchange heat with the air flow in the air duct assembly 222 to achieve heat dissipation of the radiator 221, which can not only improve the heat dissipation efficiency of the radiator 221, but also eliminate the need to set a cooling fan, thereby reducing the weight of the motorcycle 100 and realizing the lightweight of the motorcycle 100.

[0042] In this embodiment, a reference plane 103 perpendicular to the height direction of the motorcycle 100 is defined. The lowermost end of the running system 12 is disposed on the reference plane 103, and the minimum distance H 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 H 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 this application, the minimum distance H between the radiator 221 and the reference plane 103 can be 735 mm. Through the above settings, it can not only prevent the height of the radiator 221 from being too low, resulting in damage to the radiator 221 due to collision caused by flying sand and gravel during the running of the motorcycle 100, or prevent mud splashing from blocking the radiator 221 and causing poor heat dissipation, thereby improving the working life of the radiator 221; it can also prevent the height of the radiator 221 from being too low and being unfavorable to the layout of the air guiding structure 2222 and the air outlet structure 2223, thereby improving the space utilization rate of the motorcycle 100; it can also prevent the height of the radiator 221 from being too high and interfering with the saddle system 19 and affecting the layout of the saddle system 19, so that the saddle system 19 can cover the radiator 221, reduce the adhesion of dust on the surface of the radiator 221, and further improve the working life of the radiator 221.

[0043] In this embodiment, the projection of the foremost end of the radiator 221 on the reference plane 103 in the height direction of the motorcycle 100 is the first projection line, the projection of the rearmost end of the radiator 221 on the reference plane 103 in the height direction of the motorcycle 100 is the second projection line, the projection of the axis of the front wheel 121 on the reference plane 103 in the height direction of the motorcycle 100 is the third projection line, and the projection of the axis of the rear wheel 122 on the reference plane 103 in the height direction of the motorcycle 100 is the fourth projection line. The minimum distance between the first projection line and the third projection line in the length direction of the motorcycle 100 is the first distance D1, and the minimum distance between the second projection line and the fourth projection line in the length direction of the motorcycle 100 is the second distance D2. The ratio of the first distance D1 to the second distance D2 is greater than or equal to 2.1 and less than or equal to 2.6. Specifically, the ratio of the first distance D1 to the second distance D2 is greater than or equal to 2.2 and less than or equal to 2.5. In the embodiment of the present application, the ratio of the first distance D1 to the second distance D2 is 2.35. Through the above settings, it is possible to avoid the ratio of the first distance D1 to the second distance D2 from being too large, so as to avoid the position of the radiator 221 being too close to the rear side of the motorcycle 100, resulting in 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. It is also possible to avoid the ratio of the first distance D1 to the second distance D2 from being too small, so as to avoid the position of the radiator 221 being too close to the front side of the motorcycle 100, resulting in interference between the radiator 221 and the power battery 14, which is not conducive to the arrangement of the power battery 14. Thus, the radiator 221 can be located at a suitable arrangement position, avoiding interference with other components of the motorcycle 100, improving the layout rationality of the radiator 221, and also being conducive to arranging the radiator 221 between the air guiding structure 2222 and the air exhausting structure 2223, improving the heat dissipation effect of the radiator 221.

[0044] As an implementation manner, a limiting plane 109 perpendicular to the height direction of the motorcycle 100 is defined. The uppermost end of the power assembly 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. Through the above arrangement, the length of the cooling pipeline 223 between the radiator 221 and the power assembly 13 can be reduced. Without interfering with other components of the motorcycle 100, it is convenient to arrange the cooling pipeline 223 between the radiator 221 and the power assembly 13, thereby improving the structural compactness of the motorcycle 100. As an implementation manner, the frame 11 further includes a sub-frame 117. The main frame 111 and the sub-frame 117 are basically distributed along the length direction of the motorcycle 100, and the main frame 111 and the sub-frame 117 are fixedly connected. Specifically, the sub-frame 117 surrounds to form a sub-accommodating space 1171, and the radiator 221 is located in the sub-accommodating space 1171 and connected to the sub-frame 117. The suspension system 15 further includes a front suspension 151 connecting the frame 11 and the rear wheel 122 and a shock absorber 153 connecting the rear swing arm 152 and the frame 11. The radiator 221 is at least partially located at the rear side of the shock absorber 153. Through the above arrangement, both the structural compactness of the motorcycle 100 can be improved, and the interference between the radiator 221 and the shock absorber 153 during the movement of the motorcycle 100 can be avoided, improving the working life and connection stability of the radiator 221.

[0045] Such as Figure 9 , Figure 10 and Figure 11As shown, as an implementation, the cooling system further includes a filling pipe 224 and a connecting pipe 225. The filling pipe 224 and the radiator 221 are communicated through the connecting pipe 225. The saddle system 19 includes a seat cushion 193. A seat cushion accommodation space 1931 is formed by the downward depression of the lower surface of the seat cushion 193. At least a part of the filling pipe 224 is located in the seat cushion accommodation space 1931. Along the height direction of the motorcycle 100, at least a part of the filling pipe 224 is located between the saddle system 19 and the radiator 221. At least a part of the filling pipe 224 and the connecting pipe 225 are arranged above the radiator 221. The filling pipe 224 is used to add coolant and make the coolant flow to the radiator 221 through the connecting pipe 225, and then flow to the power assembly 13 through the cooling pipe 223. By adding coolant, the coolant in the cooling pipe 223 can always maintain a high capacity, so as to improve the heat transfer efficiency of the power assembly 13 to the radiator 221, and further improve the heat dissipation efficiency of the cooling system 22. Among them, in the prior art, a secondary water tank is usually provided. The coolant is filled into the secondary water tank and then flows into the radiator through the secondary water tank. The secondary water tank is used to temporarily store the coolant to balance the internal and external pressure differences. In the embodiment of the present application, the connecting pipe 225 is used to temporarily store the coolant. When the pressure in the radiator 221 is relatively high, the coolant can flow back to the connecting pipe 225. When the pressure in the radiator 221 is relatively low, the coolant can flow from the connecting pipe 225 into the radiator 221. Through the above settings, there is no longer a secondary water tank, but it is directly connected to the radiator 221 through the connecting pipe 225, so that the structure of the cooling system 22 can be simplified, the overall vehicle weight of the motorcycle 100 can be reduced, the lightweight of the motorcycle 100 can be realized, and the layout of the filling pipe 224 and the connecting pipe 225 can be facilitated, and the structural compactness of the motorcycle 100 can be improved.

[0046] In addition, an overflow port 2241 is provided on the filling pipe 224. The overflow port 2241 communicates the connecting pipe 225 with the outside. The cooling system 22 further includes an overflow pipe 226. One end of the overflow pipe 226 communicates with the overflow port 2241, and the other end of the overflow pipe 226 communicates with the outside. Through the above settings, when the pressure in the radiator 221 is greater than the external pressure and the connecting pipe 225 is filled with coolant, the coolant can flow to the outside through the overflow pipe 226; when the pressure in the cooling pipe 223 is less than the external pressure and there is no coolant in the connecting pipe 225, air can enter the radiator 221 from the overflow pipe 226, so that the internal and external pressure differences of the cooling pipe 223 can be balanced, a stable working environment for the radiator 221 can be provided, and the working life of the radiator 221 can be further improved. The overflow pipe 226 can also make the coolant flowing out of the radiator 221 flow directly to the ground, avoiding the coolant dripping from the overflow port 2241 and corroding other electrical equipment, so as to avoid potential safety hazards.

[0047] In this embodiment, the filling pipe 224 includes a filling portion 2242 and a connecting portion 2243. The filling portion 2242 is located above the connecting portion 2243. The upper surface of the subframe 117 extends substantially along the preset plane 203, and at least a part of the filling portion 2242 is located above the preset plane 203. The connecting portion 2243 can be set as a cylindrical pipe. The connecting portion 2243 communicates with the connecting pipeline 225. A filling cap 2242a for preventing coolant from overflowing is provided on the filling portion 2242. When the filling cap 2242a is opened, the filling portion 2242 communicates with the outside. A connecting member 2244 is further provided on the filling pipe 224. The fastener is at least partially passed through the connecting member 2244 and then fixedly connected to the vehicle frame 11. Specifically, the connecting member 2244 can be arranged close to the filling portion 2242 to improve the connection stability of the filling portion 2242. The filling portion 2242 can be set as a funnel shape to facilitate the filling of the coolant and avoid leakage during the filling of the coolant. Further, at least a part of the filling portion 2242 is located above the subframe 117, and the filling portion 2242 is also located below the saddle system 19. Through the above arrangement, the user only needs to open the saddle system 19 to fill the coolant through the filling portion 2242, which improves the speed of the user filling the coolant and thus improves the user experience.

[0048] As an embodiment, the connecting pipeline 225 is sleeved on the connecting portion 2243. The heat dissipation system 22 further includes a locking member 227, and the locking member 227 is sleeved on the connection between the connecting pipeline 225 and the connecting portion 2243. The radiator 221 further includes a water inlet pipe 2211. At least a part of the water inlet pipe 2211 is arranged in the upper part of the radiator 221. At least a part of the connecting pipeline 225 is sleeved on the water inlet pipe 2211, and the locking member 227 is sleeved on the connection between the connecting pipeline 225 and the water inlet pipe 2211. Among them, the locking member 227 can be set as a hose clamp or the like, so that it is convenient for the locking and disassembly of the locking member 227. Through the above arrangement, the locking member 227 can fixedly connect the connecting pipeline 225 to the connecting portion 2243 and the water inlet pipe 2211, so as to avoid the leakage of the coolant at the connection between the connecting pipeline 225 and the connecting portion 2243 or at the connection between the connecting pipeline 225 and the water inlet pipe 2211, so as to avoid the waste of the coolant or the corrosion caused by the coolant dropping to other electrical equipment and generating potential safety hazards, and further improve the connection stability of the connecting pipeline 225 and the safety of the motorcycle 100.

[0049] In this embodiment, the connecting pipeline 225 can be set as a rubber part. Through the above arrangement, the rubber connecting pipeline 225 has a certain elastic deformation ability, which is convenient for connecting the connecting portion 2243 and the water inlet pipe 2211 with different connection opening directions, so as to facilitate the layout of the connecting pipeline 225 and the filling pipe 224 and improve the structural compactness of the motorcycle 100.

[0050] Specifically, the inner diameter of the connecting pipeline 225 is greater than the outer diameter of the connecting part 2243, and the inner diameter of the connecting pipeline 225 is greater than the outer diameter of the water inlet pipe 2211, so that it is convenient for the connecting pipeline 225 to be sleeved outside the connecting part 2243 and the water inlet pipe 2211. And the locking part 227 is sleeved on the connecting pipeline 225 to generate pressure on the rubber connecting pipeline 225, causing the connecting pipeline 225 to have elastic deformation, so that the connection between the connecting pipeline 225 and the connecting part 2243 is tighter, and the connection between the connecting pipeline 225 and the water inlet pipe 2211 is tighter. Furthermore, the sealing performance at the connection between the connecting pipeline 225 and the connecting part 2243 can be improved, and the sealing performance at the connection between the connecting pipeline 225 and the water inlet pipe 2211 can be improved to avoid leakage of the coolant.

[0051] As Figure 12 shown, as an implementation manner, the heat dissipation system 22 further includes a water pump structure 228. The water pump structure 228 is connected to the radiator 221 and the power assembly 13 through the cooling pipeline 223. The cooling pipeline 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 pipeline 223. Thus, the coolant carries heat and flows out from the power assembly 13, flows to the radiator 221 for heat dissipation under the action of the water pump structure 228, and returns to the power assembly 13 after cooling, realizing the heat dissipation of the power assembly 13 by the heat dissipation system 22. Among them, the water pump structure 228 can be set as a combined structure of a brushless motor and an impeller. The brushless motor and the impeller are rotationally connected, and the impeller is driven to rotate by the brushless motor to make the coolant flow in the loop. Specifically, the water pump structure 228 is located at the rear side of the shock absorber 153, and at least part of the water pump structure 228 is located at the front side of the rear fender 164. At least part of the water pump structure 228 is also arranged in the secondary accommodation space 1171. Through the above settings, the length of the cooling pipeline 223 can be reduced, which is convenient for the layout of the cooling pipeline 223, improves the structural compactness and space utilization rate of the motorcycle 100, and is also convenient for the disassembly and maintenance of the water pump structure 228, thereby improving the assembly performance and maintenance performance of the water pump structure 228. In addition, the water pump structure 228 is located at the rear side of the shock absorber 153 and at the front side of the rear fender 164, which can avoid interference between the water pump structure 228 and the shock absorber 153 or the rear fender 164. At least part of the water pump structure 228 being arranged in the secondary accommodation space 1171 can also enable the frame 11 to provide a protective effect for the water pump structure 228.

[0052] In this embodiment, at least part of the water pump structure 228 is located at the rear side of the radiator 221. Through the above settings, the water pump structure 228 is arranged close to the radiator 221, which can reduce the layout of the cooling pipeline 223, thereby improving the structural compactness of the motorcycle 100, and further improving the space utilization rate of the motorcycle 100.

[0053] 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 settings, it is possible to avoid excessive distance between the water pump structure 228 and the shock absorber 153, which takes up 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 interference between the water pump structure 228 and the shock absorber 153 and the rear fender 164 due to excessive distance, thereby improving the space utilization rate of the motorcycle 100; it is also possible to avoid the shock absorber 153 colliding with the water pump structure 228 during movement due to too small a distance between the water pump structure 228 and the shock absorber 153, so as to avoid damage to the water pump structure 228, thereby improving the working life of the water pump structure 228.

[0054] In the present embodiment, the water pump structure 228 is located above the limiting plane 109, and the water pump structure 228 is at least partially disposed below the radiator 221. Through the above settings, it is possible to reduce the length of the cooling pipeline 223 between the water pump structure 228 and the power assembly 13, and it is also possible to reduce the length of the cooling pipeline 223 between the water pump structure 228 and the radiator 221, thereby facilitating the layout of the cooling pipeline 223 and improving the structural compactness of the motorcycle 100.

[0055] As Figure 13 shown, in the present embodiment, the water pump structure 228 is fixedly connected to the sub-frame 11. Specifically, an installation bracket 1173 is provided on the sub-frame 11, and the water pump structure 228 is fixedly connected to the sub-frame 11 through the installation bracket 1173. Through the above settings, the connection strength of the water pump structure 228 can be improved, and during the movement of the motorcycle 100, it is possible to avoid the water pump structure 228 falling off due to the vibration of the motorcycle 100, thereby improving the connection stability of the water pump structure 228.

[0056] Furthermore, the water pump structure 228 extends substantially along the direction of the preset straight line 204. The direction of the preset straight line 204 refers to the axis direction of the brushless motor or the impeller in the water pump structure 228. When the water pump structure 228 is connected to the sub-frame 117, the preset straight line 204 extends substantially along the height direction of the motorcycle 100, and at this time, the water pump structure 228 is in a longitudinal state. Through the above settings, when in the longitudinal state, it is possible to reduce the layout space occupied by the water pump structure 228 and also facilitate the layout of the cooling pipeline 223, thereby improving the space utilization rate of the motorcycle 100.

[0057] As Figure 14As shown, as another implementation, the water pump structure 228 is fixedly connected to the rear fender 164 so that the rear fender 164 can provide a supporting function for the water pump structure 228, thereby reducing the number of components of the motorcycle 100. Specifically, a receiving groove 1643 is provided on the rear fender 164, and at least a part of the water pump structure 228 is disposed in the receiving groove 1643, so that the receiving groove 1643 can provide a protective function for the water pump structure 228. Among them, the motorcycle 100 is further provided with a fixing member 23 for fixing the water pump structure 228. The fixing member 23 abuts against the water pump structure 228, and the fixing member 23 is also connected to the rear fender 164. The fixing member 23 and the receiving groove 1643 surround to form a fixing space, and at least a part of the water pump structure 228 is disposed in the fixing space. Specifically, a through hole is provided on the rear fender 164. One end of the fixing member 23 at least partially passes through the through hole and is clamped with the rear fender 164, and the fastening member at least partially passes through the other end of the fixing member 23 and is fixedly connected to the rear fender 164. Through the above settings, a part of the rear fender 164 serves as a load-bearing member of the water pump structure 228, which can avoid setting an installation structure on the frame 11, thereby reducing the number of installation structures, simplifying the installation process of the water pump structure 228, facilitating the disassembly, assembly and maintenance of the water pump structure 228, and further improving the assembly performance and maintenance performance of the water pump structure 228.

[0058] It should be noted that when the water pump structure 228 is disposed in the receiving groove 1643, the preset straight line 204 extends substantially along the width direction of the motorcycle 100, and at this time the water pump structure 228 is in a horizontal state. Through the above settings, when in the horizontal state, the contact surface between the water pump structure 228 and the rear fender 164 is larger, so that the receiving groove 1643 is larger, thereby improving the connection stability and working stability of the water pump structure 228 in the receiving groove 1643.
