Description

Technical Field

[0001] This application relates to the field of vehicle engineering, and more particularly to a motorcycle. Background Technology

[0002] Motorcycle radiators facilitate heat exchange with the coolant flowing through the engine. As the vehicle moves, air passes through the radiator, cooling the coolant. The radiator fan then directs the hot air towards the rear of the radiator. To prevent hot air from escaping from the sides and causing heatstroke, a shroud is placed around the outer edge of the fan. While the shroud limits the direction of hot air flow, it also increases air resistance, reducing the radiator's cooling performance. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, the purpose of this application is to provide a motorcycle with a radiator that has better heat dissipation performance.

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

[0005] A motorcycle includes a frame, an engine, a cooling system, a seat, and a running system; the engine is supported by the frame; the cooling system includes a radiator supported by the frame, the radiator includes a fan and cooling fins, the fan being connected to the cooling fins; the running system is at least partially located below the frame and is drive-connected to the engine; the seat is supported by the frame; the cooling system further includes a fairing that covers at least a portion of the fan, the fairing including a first guide and a second guide, the first and second guides being distributed on the left and right sides of the fan, the length of the second guide being different from the length of the first guide, and one of the first and second guides being shorter than the length of the fan, so that when the fan rotates, the side with the longer guide portion directs air away from the seat.

[0006] Furthermore, viewed from the airflow direction of the radiator, the first airflow guide is located on the right side of the fan, and the second airflow guide is located on the left side of the fan. If the fan rotates clockwise, the length of the first airflow guide is greater than the length of the second airflow guide; if the fan rotates counterclockwise, the length of the first airflow guide is less than the length of the second airflow guide.

[0007] Furthermore, both the first and second air guides have air outlets that extend through themselves along the width direction of the motorcycle. The fan includes fan blades and a motor that drives the fan blades. The fan blades are distributed on the outer edge of the motor. When viewed along the width direction of the motorcycle, the air outlets partially overlap with the motor, or the air outlets are located above the motor.

[0008] Furthermore, an air duct is formed between the first air guide and the second air guide. The fan includes fan blades and a motor that drives the fan blades. The fan blades are distributed on the outer edge of the motor. When viewed from the windward side of the radiator, at least a portion of the air duct overlaps with the motor.

[0009] Furthermore, the first and second flow guides are integrally formed.

[0010] Furthermore, the fairing forms a recessed clearance area in the direction of the fan, and the engine also includes an air intake valve, at least a portion of which is located within the clearance area.

[0011] Furthermore, the fairing has a head and a tail, with the head located above the tail. The head of the fairing is connected to the radiator, and the tail of the fairing forms an arc-shaped flange structure, which is used to avoid the cylinder head cover of the engine.

[0012] Furthermore, the cooling system also includes a water tank connected to the radiator. The water tank includes a body and a filling tube connected to the body. The motorcycle also includes a body panel that, viewed along the width of the motorcycle, covers the entire body of the water tank and at least part of the filling tube, which extends from the body of the water tank toward the rear of the motorcycle and passes through the body panel.

[0013] Furthermore, the body panel includes a side guard plate and a windshield guard plate connected to the side guard plate. At least a portion of the windshield guard plate is disposed below the side guard plate. The side guard plate has a guard plate connecting portion connected to the upper edge of the windshield guard plate. The end face of the guard plate connecting portion is parallel to the width direction of the motorcycle. A notch is provided on the side guard plate connecting portion to avoid the filling pipe.

[0014] Furthermore, the kettle includes a kettle sidewall facing the air-stabilizing guard plate, and the kettle sidewall is provided with reinforcing ribs.

[0015] The motorcycle provided in this application, by setting first and second air guides of different lengths and determining the length of the side air guides in conjunction with the rotation direction of the fan, blows hot air out from the direction where the shorter air guide is located, which can avoid hot air blowing to the left and right and causing heat damage to the body, while improving the heat dissipation performance of the radiator.

[0026] To clearly illustrate the technical solutions of the embodiments of the present invention or the prior art, the accompanying drawings used in the description of the embodiments or the prior art are briefly introduced below. Obviously, the content described below is only one embodiment of the present invention. For those skilled in the art, all other embodiments obtained without creative effort are within the protection scope of the present invention.

[0027] In this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, without necessarily requiring or implying any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0028] like Figure 1As shown, this application provides a motorcycle 100, which includes a frame 11, a body panel 12, a suspension system 13, a running gear 14, and a powertrain 15. At least a portion of the body panel 12 covers the frame 11, and at least a portion of the running gear 14 is located below the frame 11 and connected to the frame 11 via the suspension system 13. The running gear 14 includes a front wheel 141 and a rear wheel 142, and the powertrain 15 is supported by the frame 11 and is drive-connected to the rear wheel 142.

[0029] For ease of description, the following are also defined: Figure 1 The motorcycle 100 is shown in the front-back, left-right, and up-down directions. In the description of this application, the length direction of the motorcycle 100 refers to the front-back direction, the width direction refers to the left-right direction, and the height direction refers to the up-down direction.

[0030] like Figure 2 As shown, the frame 11 includes a main frame 111 distributed substantially along the length of the motorcycle 100 and a subframe 112 located behind the main frame 111. The subframe 112 extends in a direction substantially the same as the main frame 111, that is, it extends substantially along the length of the motorcycle 100. The motorcycle 100 also includes a support bracket 113 extending substantially along the height of the motorcycle 100. The support bracket 113 is at least partially located between the main frame 111 and the subframe 112, and both the main frame 111 and the subframe 112 are fixedly connected to the support bracket 113. The main frame 111 and the support bracket 113 are fixed by welding, and the subframe 112 is bolted to the support bracket 113. The powertrain 15 includes an engine 151 located below the main frame 111 and connected to the main frame 111 and the support bracket 113.

[0031] like Figure 3 and Figure 4 As shown, the pair of frame tubes at the top of the main frame 111, distributed along the width direction of the motorcycle 100, are defined as the upper main beams 1111 of the main frame 111. The pair of upper main beams 1111 extend substantially along the length direction of the motorcycle 100 and are fixedly connected to the support bracket 113. The powertrain 15 also includes an air filter 152, which is connected to the main frame 111 and the engine 151. The air filter 152 is located above the engine 151, and at least a portion of the air filter 152 is disposed between the pair of upper main beams 1111. The motorcycle 100 also includes a fuel tank 19 (see...). Figure 1 The fuel tank 19 is supported by the frame 11 and covers the air filter 152.

[0032] In one implementation, the main frame 111 also includes a head tube 1112, a fuel tank support 1113, and an air filter support 1114. One end of the upper main beam 1111 facing away from the support bracket 113 is connected to the head tube 1112. The fuel tank support 1113 is positioned close to the head tube 1112 and arranged between a pair of upper main beams 1111. Both ends of the fuel tank support 1113 are fixedly connected to the upper main beams 1111 on both sides, and the fuel tank support 1113 supports the fuel tank 19. The air filter support 1114 is connected to the fuel tank support 1113, and the air filter 152 is at least partially supported by the air filter support 1114. Specifically, the front of the air filter 152 is supported by and fixedly connected to the air filter support 1114, and the rear of the air filter 152 is supported by the engine 151 and fixedly connected to the cylinder head 1511 of the engine 151. The air filter 152 has an air outlet 1521, which is connected to the air intake passage 1511b of the cylinder head 1511. The air outlet 1521 of the air filter 152 is fastened to the air intake passage 1511b of the cylinder head 1511 by a clamp structure.

[0033] With the above configuration, there is no need to install a mounting structure for fixing the air filter 152 on the main frame 111, reducing the number of welding points on the main frame 111, improving the overall vehicle assembly efficiency, and the air filter 152 still maintains good stability. In addition, since the air filter support 1114 can be hidden inside the frame 11, the risk of damage to the connection between the air filter support 1114 and the air filter 152 can be reduced, and the overall appearance of the vehicle is more aesthetically pleasing.

[0034] Furthermore, at least a portion of the air filter support 1114 extends downward from the fuel tank support 1113, forming a support platform 1114a at the bottom of the air filter support 1114 for supporting the air filter 152. The air filter 152 has a fixing portion 1522 extending toward the air filter support 1114, the fixing portion 1522 being integrally formed with the housing of the air filter 152, and the fixing portion 1522 being fixedly connected to the support platform 1114a.

[0035] The air filter support 1114 is a zigzag-shaped sheet metal component. One end of the air filter support 1114 contacts the fuel tank support 1113 and is fixedly connected to it by riveting. The other end of the air filter support 1114 forms a support platform 1114a, which contacts the fixing part 1522 of the air filter 152 and is fixedly connected to it by bolts. Due to the high ductility of sheet metal components, the shape of the air filter support 1114 can be flexibly adjusted according to the installation position of the air filter 152, and the modification cost is low.

[0036] Specifically, a limiting groove 1113a is formed on the fuel tank support 1113, located on the side edge of the fuel tank support 1113 facing the air filter 152. At least a portion of the air filter support 1114 is fixed to the upper surface of the fuel tank support 1113, and at least a portion of the air filter support 1114 passes through the limiting groove 1113a and extends downward. The left and right side walls of the limiting groove 1113a are clearance-fitted with the air filter support 1114, limiting the air filter support 1114 in the width direction of the motorcycle 100 through the limiting groove 1113a of the fuel tank support 1113.

[0037] During the installation of the air filter support 1114, the air filter support 1114 is first inserted into the limiting groove 1113a for initial positioning to prevent the air filter support 1114 from rotating or shifting during assembly. Then, the air filter support 1114 is fixedly connected to the fuel tank support 1113 using fasteners. This ensures that the installation angle and position of the air filter support 1114 relative to the fuel tank support 1113 are accurate, thereby improving the assembly consistency between the air filter 152 and the air filter support 1114.

[0038] like Figure 4 As shown, in one implementation, the powertrain 15 also includes a supplementary air valve 153. The supplementary air valve 153 receives filtered air from the air filter 152 and supplements the air to the engine 151, thereby optimizing the air-fuel ratio in the combustion chamber of the engine 151 and keeping the engine 151 in optimal combustion condition. The supplementary air valve 153 is connected to both the air filter 152 and the engine 151. In addition to the aforementioned air outlet 1521, the air filter 152 is also provided with a supplementary air port 1523. The cylinder head cover 1511a of the engine 151 is provided with a supplementary air passage 1511c that communicates with the intake passage 1511b. The supplementary air valve 153 is connected to the supplementary air port 1523 through an air pipe 1532, and the supplementary air valve 153 is also connected to the supplementary air passage 1511c on the cylinder head cover 1511a. The air replenishment valve 153 includes an air inlet 1533 connected to the air pipe 1532 and an air outlet 1534 connected to the air replenishment channel 1511c. The air pipe 1532 includes a first connecting end 1532a and a second connecting end 1532b. The first connecting end 1532a of the air pipe 1532 is connected to the air replenishment port 1523, and the second connecting end 1532b of the air pipe 1532 is connected to the air replenishment port 1523. In this embodiment, the air replenishment valve 153 is located in front of the air filter 152. Viewed along the length of the motorcycle 100, the air replenishment valve 153 overlaps with the air filter 152. Through the above arrangement, the length of the air pipe between the air replenishment port 1523 and the air replenishment valve 153, and between the air replenishment valve 153 and the air replenishment channel 1511c, are shortened, the difficulty of arranging the two sections of air pipe is reduced, and the compactness of the overall vehicle structure is improved.

[0039] Furthermore, the frame 11 also includes an air replenishment valve bracket 114, which is fixed to the air filter 152. At least a portion of the air replenishment valve bracket 114 extends forward toward the motorcycle 100 and engages with the air replenishment valve 153.

[0040] The air replenishment valve bracket 114 is fixed to the front end face of the air filter 152. The air replenishment valve bracket 114 can be a sheet metal structure, which has a first panel 1141 and a second panel 1142. At least a portion of the first panel 1141 is attached to the outer wall of the air filter 152, and the second panel 1142 extends in the direction of the air replenishment valve 153, that is, extends in front of the motorcycle 100, until at least a portion of the second panel 1142 can support the air replenishment valve 153. The second panel 1142 is perpendicular to the first panel 1141, thereby improving the structural strength of the air replenishment valve bracket 114 and giving the air replenishment valve bracket 114 a more stable support effect for the air replenishment valve 153.

[0041] Specifically, the second panel 1142 has a recess 1142a, which is used to avoid the air pipe or electrical control connector connected to the air supply valve 153.

[0042] Optionally, both the first panel 1141 and / or the second panel 1142 are provided with a hollow structure 1143 to reduce the weight of the air supply valve bracket 114.

[0043] In one implementation, the air replenishment valve bracket 114 includes a pair of parallel fixed shafts 1144. The extending direction of the fixed shafts 1144 is substantially parallel to the width direction of the motorcycle 100, and the pair of fixed shafts 1144 are distributed substantially along the length direction of the motorcycle 100. An air replenishment valve 153 is disposed between the pair of fixed shafts 1144. The air replenishment valve 153 includes a pair of latches 1531, which are distributed on the front and rear sides of the air replenishment valve 153. The pair of latches 1531 of the air replenishment valve 153 engage with the fixed shafts 1144 in the corresponding directions. Optionally, the specific position of the pair of latches 1531 can be adaptively adjusted according to the installation direction of the air replenishment valve 153.

[0044] Furthermore, a pair of limiting rings 1144a are provided on the outer edge of the fixed shaft 1144, and the pair of limiting rings 1144a are distributed along the axial direction of the fixed shaft 1144. When the pawl 1531 engages with the fixed shaft 1144, the pawl 1531 is located between the pair of limiting rings 1144a, and the pair of limiting rings 1144a limits the air supply valve 153 in the width direction of the motorcycle 100.

[0045] Optionally, a rubber part 1144b is sleeved on the outer edge of the fixed shaft 1144. The rubber part 1144b is disposed between a pair of limiting rings 1144a. The claw 1531 engages with the outer edge of the rubber part 1144b, thereby reducing the hard friction between the air supply valve 153 and the air supply valve bracket 114, alleviating the direct impact between rigid structures, and thus extending the service life of the air supply valve bracket 114.

[0046] like Figure 5 As shown, the motorcycle 100 also includes a cooling system 16, at least a portion of which is supported by the frame 11. The cooling system 16 includes a radiator 161, an inlet pipe 162, and an outlet pipe 163. The engine 151 includes a coolant outlet (not shown) and a coolant inlet (not shown). Coolant in the engine 151 can leave the engine through the coolant outlet, and coolant flowing through the radiator 161 can enter the engine 151 through the coolant inlet. The radiator 161 is connected to the coolant outlet of the engine 151 through the outlet pipe 163, and the radiator 161 is connected to the coolant inlet of the engine 151 through the inlet pipe 162.

[0047] like Figure 5 and Figure 6 As shown, the radiator 161 includes heat dissipation fins 1611 and water chambers 1612. The water chambers 1612 have a space for providing a flow channel for coolant. The water chambers 1612 are distributed on the left and right sides of the heat dissipation fins 1611. The water chambers 1612 arranged on one side of the heat dissipation fins 1611 are used to receive the coolant pumped in from the outlet pipe 163 and guide the coolant into the heat dissipation fins 1611 for heat exchange. The water chambers arranged on the other side of the heat dissipation fins 1611 are used to receive the coolant after heat exchange and transport the coolant to the inlet pipe 162.

[0048] Specifically, the water chamber 1612 includes an inlet chamber 1612a and an outlet chamber 1612b. The inlet chamber 1612a is located on one side of the heat dissipation fins 1611 and is connected to the outlet pipe 163 of the engine 151. The inlet chamber 1612a is used to receive the high-temperature coolant pumped out by the engine 151. The outlet chamber 1612b is located on the other side of the heat dissipation fins 1611 and is connected to the inlet pipe 162 of the engine 151. The outlet chamber 1612b is used to send the cooled coolant into the engine 151 to achieve coolant circulation.

[0049] In one implementation, the water inlet chamber 1612a is divided from top to bottom into a first water chamber 1612c and a second water chamber 1612f along the height direction of the motorcycle 100, with the space within the first water chamber 1612c communicating with the space within the second water chamber 1612f. Specifically, the water inlet chamber 1612a has a side wall extending along the height direction of the motorcycle 100, which includes a first side wall 1612d and a second side wall 1612g connected together, with the first side wall 1612d located above the second side wall 1612g. That is, the first side wall 1612d is located on the side of the first water chamber 1612c closer to the engine 151, and the second side wall 1612g is located on the side of the second water chamber 1612f closer to the engine 151. In this embodiment, the first sidewall 1612d and the second sidewall 1612g are both rear sidewalls of the water inlet chamber 1612a. The first sidewall 1612d has an inlet port 1612e for connecting to the outlet pipe 163. The inlet port 1612e is a through hole for introducing coolant into the water inlet chamber 1612a. This shortens the length of the inlet pipe 162 and the outlet pipe 163, improving the coolant circulation efficiency.

[0050] In one implementation, the angle between the first sidewall 1612d and the second sidewall 1612g ranges from 135° to 180°. Further, the angle between the first sidewall 1612d and the second sidewall 1612g ranges from 140° to 171°. More preferably, the angle between the first sidewall 1612d and the second sidewall 1612g ranges from 144° to 162°. It should be noted that if the included angle α is too large, the connection angle between the outlet pipe 163 and the inlet 1612e will be large, causing the portion of the outlet pipe 163 near the inlet 1612e to bulge upwards, forming a bent coolant flow channel. This bent flow channel will obstruct coolant flow and create trapped air bubbles, affecting the exhaust performance of the cooling system 16 and potentially even causing pump cavitation. Conversely, if the included angle α is too small, the portion of the outlet pipe 163 near the inlet 1612e will be concave downwards, similarly forming a bent coolant flow channel and affecting the exhaust performance of the cooling system 16. This design improves coolant circulation efficiency and prevents pump cavitation.

[0051] As one implementation method, a reference plane 104 is defined perpendicular to the height direction of the motorcycle 100. The water outlet pipe 163 includes a front water pipe 1631 connected to the inlet 1612e. The upper edge of the front water pipe 1631 is basically parallel to the reference plane 104 to avoid the front water pipe 1631 from forming a bulge and causing air to be trapped.

[0052] Furthermore, the angle between the first sidewall 1612d and the second sidewall 1612g is defined as the first included angle α, and the angle between the oncoming airflow of the radiator 161 and the reference plane 104 is defined as the second included angle β. The first included angle α and the second included angle β are approximately equal. Through the above arrangement, the extension direction of the front water pipe 1631 is substantially coincident with the extension direction of the centerline of the liquid inlet 1612e, preventing the front water pipe 1631 from forming a bulge that would cause air stagnation. The liquid inlet 1612e is a circular through-hole, and the centerline of the liquid inlet 1612e coincides with the circle of the liquid inlet 1612e.

[0053] As one implementation, at least a portion of the second water chamber 1612f is recessed into the interior of the second water chamber 1612f in the direction F perpendicular to the wind direction of the radiator 161. That is, the interior space of the second water chamber 1612f is narrower than the interior space of the first water chamber 1612c, and a local low-volume region is formed in the space of the second water chamber 1612f.

[0054] Specifically, the water inlet chamber 1612a is divided into a first water storage section 1612h and a second water storage section 1612i along the width direction of the motorcycle 100. The second water storage section 1612i is located between the first water storage section 1612h and the heat dissipation fins 1611. In the direction F perpendicular to the wind direction of the radiator 161, the width of the second water storage section 1612i is greater than the width of the first water storage section 1612h.

[0055] Optionally, a longitudinal plane 107 perpendicular to the width direction of the motorcycle 100 is defined, and the area of ​​the orthographic projection of the first water storage part 1612h on the longitudinal plane 107 is smaller than the area of ​​the orthographic projection of the second water storage part 1612i on the longitudinal plane 107.

[0056] In this embodiment of the application, the first sidewall 1612d and the second sidewall 1612g are both located in the first water storage section 1612h.

[0057] As an alternative implementation, the water outlet chamber 1612b can also be divided into two water storage sections along the width direction of the motorcycle 100, and the two water storage sections have different widths in the direction F perpendicular to the wind direction of the radiator 161, wherein the width of the water storage section closer to the radiator is larger than the width of the other water storage section.

[0058] The above settings optimize the structural layout of the water chamber 1612, making the demolding process smoother, thereby significantly simplifying the manufacturing process, reducing operational complexity, and ultimately saving demolding costs during production.

[0059] like Figure 7As shown, the radiator 161 includes a fan 1613, which is connected to the heat dissipation fins 1611. The radiator 161 has a frontal surface 101 facing the front of the motorcycle 100 (see [reference]). Figure 6 The fan 1613 is located on the opposite side of the radiator 161 from the airflow side 101. The cooling system 16 includes a shroud 164 connected to the radiator 161 and covering at least part of the fan 1613. The shroud 164 includes a first airflow guide 1641 and a second airflow guide 1642, which are distributed on the left and right sides of the fan 1613. Viewed along the width of the motorcycle 100, the length L2 of the second airflow guide 1642 is different from the length L1 of the first airflow guide 1641. The lengths L1 and L2 of the first airflow guide 1641 and the second airflow guide 1642 are related to the rotation direction of the fan 1613. The length of one of the first airflow guide 1641 and the second airflow guide 1642 is less than the length of the fan 1613, so that when the fan 1613 rotates, the longer airflow guide guides the air away from the seat. The seat is supported by the frame 11.

[0060] To clearly illustrate the technical solution of this application, when viewed along the width direction of the motorcycle 100, the line connecting the highest point to the lowest point of the fairing 164 extends along a predetermined direction. The length L1 of the first guide member 1641 refers to the length of the first guide member 1641 extending along the predetermined direction, and the length L2 of the second guide member 1642 refers to the length of the second guide member 1642 extending along the predetermined direction. Similarly, in the embodiment of this application, the length of the fan 1613 refers to the length of the fan 1613 extending along the predetermined direction.

[0061] For example, viewed from the windward side 101 of the radiator 161, at least a portion of the first air guide 1641 is located to the right of the fan 1613, and at least a portion of the second air guide 1642 is located to the left of the fan 1613. If the fan 1613 rotates clockwise, the length L1 of the first air guide 1641 is greater than the length L2 of the second air guide 1642, and the length L2 of the second air guide 1642 is less than the length of the fan 1613. In the specific heat dissipation process, cold air passes through the heat dissipation fins 1611 and exchanges heat with them. The fan 1613 rotates clockwise, blowing the hot air generated after heat exchange toward the first air guide 1641. When the fan 1613 rotates clockwise, the volume of hot air blown toward the first air guide 1641 is greater than the volume of hot air blown toward the second air guide 1642. Therefore, the exterior parts on the left side of the motorcycle 100 can be prevented from being affected by hot air, resulting in a higher temperature and improving the user's driving experience.

[0062] Optionally, viewed from the direction perpendicular to the windward side 101 of the heat sink 161, at least a portion of the first airflow guide 1641 is located to the right of the fan 1613, and at least a portion of the second airflow guide 1642 is located to the left of the fan 1613. If the fan 1613 rotates counterclockwise, the length L1 of the first airflow guide 1641 is less than the length L2 of the second airflow guide 1642, and the length L1 of the first airflow guide 1641 is less than the length of the fan 1613. In the specific heat dissipation process, cold air passes through the heat dissipation fins 1611 and exchanges heat with them. The fan 1613 rotates counterclockwise, blowing the hot air generated after heat exchange toward the second airflow guide 1642. When the fan 1613 rotates clockwise, the volume of hot air blown toward the second airflow guide 1642 is greater than the volume of hot air blown toward the first airflow guide 1641. Therefore, it can prevent the exterior parts on the right side of the motorcycle from being affected by hot air, thus avoiding their high temperature and improving the user's driving experience.

[0063] With the above settings, the first guide 1641 and the second guide 1642 of different lengths are set according to the rotation direction of the fan 1613 to prevent the disorderly diffusion or backflow of hot air to the radiator 161, optimize the airflow direction of hot air, so that the hot air will not blow directly towards the driver or exterior parts, reduce the discomfort caused by hot air blowing towards the driver, and improve the comfort during driving.

[0064] In the embodiments of this application, the first guide member 1641 and the second guide member 1642 are integrally formed.

[0065] To clearly illustrate the technical solution of this application, in the following description of the technical solution, the fan 1613 rotates counterclockwise and the length L1 of the first guide member 1641 is less than the length L2 of the second guide member 1642, as an example to further illustrate the technical solution of this application.

[0066] In one implementation, both the first air guide 1641 and the second air guide 1642 have an air outlet 1643 extending through them along the width direction of the motorcycle 100. Exemplarily, the air outlet 1643 on the first air guide 1641 is defined as the first air outlet, and the air outlet 1643 on the second air guide 1642 is defined as the second air outlet. Hot air blown towards the second air guide 1642 is discharged through the second air outlet, exiting the space formed by the second air guide 1642 and the fan 1613. Furthermore, a small portion of the hot air generated by the fan 1613's rotation is blown towards the first air guide 1641, and this hot air is also discharged through the first air outlet, exiting the space formed by the first air guide 1641 and the fan 1613. This prevents disorderly diffusion or backflow of hot air into the radiator 161, reducing the airflow resistance of the cooling system 16 and thereby improving the heat dissipation performance of the radiator 161.

[0067] Furthermore, the fan 1613 includes fan blades 1613a and a motor 1613b that drives the fan blades 1613a. The fan blades 1613a are distributed around the outer edge of the motor 1613b and are able to rotate around the outer edge of the motor 1613b under the action of the motor 1613b. Viewed along the width direction of the motorcycle 100, the air outlet 1643 overlaps with a portion of the motor 1613b, or at least a portion of the air outlet 1643 is located above the motor 1613b.

[0068] When the rider is riding the motorcycle 100, a portion of the rider's legs are in contact with the air vent 1214. This design prevents hot air from the vent 1643 from blowing onto a portion of the air vent 1214, thus improving riding comfort.

[0069] As one implementation, the shroud 164 also forms an air vent 1644, located between the first air guide 1641 and the second air guide 1642. Viewed from the direction perpendicular to the windward surface 101 of the radiator 161, the air vent 1644 overlaps with at least a portion of the motor 1613b. When air passes through the radiator 161 in a direction perpendicular to the windward surface 101, some air is blown towards the first air guide 1641 and the second air guide 1642 by the fan 1613, and then blown towards the left and right sides of the motorcycle 100's wind deflector 1214 via the air outlet 1643. The remaining air passes through the fan blades 1613a of the fan 1613 and is blown towards the rear of the fan 1613 via the air vent 1644. Through the above arrangement, in addition to cooling the motor 1613b, the airflow resistance of the cooling system 16 is reduced, thereby improving the heat dissipation performance of the radiator 161.

[0070] In one implementation, the air deflector 164 forms a recessed clearance area 1645 towards the fan 1613, and at least a portion of the air intake valve 153 is located within the clearance area 1645. In this embodiment, the air intake valve 153 is positioned close to the second air guide 1642; therefore, at least a portion of the second air guide 1642 may interfere with the air intake valve 153, and the clearance area 1645 is located within the second air guide 1642. Viewed from the windward side 101 perpendicular to the radiator 161, the clearance area 1645 overlaps with at least a portion of the air intake valve 153. This arrangement makes the arrangement of the cooling system 16 and the engine 151 more compact, improving the overall space utilization of the vehicle.

[0071] In one implementation, the fairing 164 has a head 1646 and a tail 1647, with the head 1646 located above the tail 1647. The head 1646 is fixedly connected to the radiator 161, and the tail 1647 forms an arc-shaped flange structure 1647a. The flange structure 1647a is located on the portion of the fairing 164 near the cylinder head cover 1511a of the engine 151, and is used to avoid the cylinder head cover 1511a of the engine 151. In this embodiment, the flange structure 1647a changes the airflow by less than 1%. The cylinder head cover 1511a of the engine 151 is typically located on the upper part of the engine 151. If the tail 1647 of the fairing 164 extends directly, it may interfere with the installation or maintenance of the cylinder head cover 1511a. By forming an arc-shaped flange structure 1647a at the tail of the fairing 164, the flange structure 1647a can effectively avoid the cylinder head cover 1511a. The arc-shaped structure can reduce the change in airflow. The design of the arc-shaped flange structure 1647a can ensure the smooth installation of the fairing 164 without affecting the heat dissipation effect of the heat dissipation system 16.

[0072] like Figures 8 to 10 As shown, the cooling system 16 also includes a water tank 165, which is used to replenish the coolant in the radiator 161, engine 151 and related cooling water circuits, to ensure that the coolant level of the cooling system 16 is stable during long-term operation and to prevent the cooling performance of the cooling system 16 from decreasing due to evaporation or leakage of coolant.

[0073] In one implementation, the water tank 165 is positioned on the left or right side of the engine 151. Viewed along the width of the motorcycle 100, the water tank 165 overlaps with the engine 151. The water tank 165 includes a tank body 1651 and a filling pipe 1652 connected to the tank body 1651. The body cover 12 covers at least part of the engine 151 and all of the tank body 1651. The filling pipe 1652 extends from the tank body 1651 toward the rear of the motorcycle 100 and passes through the body cover 12.

[0074] Specifically, the kettle 165 also includes a lid 1653, which is located at the end of the filling tube 1652 away from the kettle body 1651 and is used to seal the filling tube 1652.

[0075] During the process of adding coolant, the lid 1653 can be removed from the end of the filling tube 1652 away from the body 1651, and coolant can be injected into the filling tube 1652 to stabilize the liquid level in the heat dissipation system 16.

[0076] With the above settings, the coolant filling operation can be completed without disassembling the body panel 12, improving the convenience of coolant filling.

[0077] like Figure 10 As shown, in one implementation, the body panel 12 includes a side guard plate 1213 and a wind guard plate 1214 connected to the side guard plate 1213. The side guard plate 1213 and the wind guard plate 1214 are distributed on the left and right sides of the frame 11.

[0078] To clearly illustrate the technical solution of this application, only the side guard plate 1213 and the windshield guard plate 1214 in the direction of the water bottle 165 will be described in detail below. The side guard plate 1213 is connected to the frame 11, and at least a portion of the windshield guard plate 1214 is disposed below the side guard plate 1213 and fixedly connected to the side guard plate 1213. Viewed along the width direction of the motorcycle 100, the windshield guard plate 1214 covers at least a portion of the engine 151 and the entire water bottle body 1651. The side guard plate 1213 has a guard plate connecting portion 1213a connected to the upper edge of the windshield guard plate 1214. The guard plate connecting portion 1213a is disposed at the lower edge of the side guard plate 1213. The guard plate connecting portion 1213a is a plate-like structure extending along the width direction of the motorcycle 100, that is, the guard plate connecting portion 1213a has two opposing end faces, which are substantially parallel to the width direction of the motorcycle 100.

[0079] Specifically, a housing space is formed between the windshield guard 1214 and the engine 151, and the water tank 165 is disposed in the housing space and located behind the radiator 161. This housing space provides a stable mounting position for the water tank 165, preventing the water tank 165 from being directly exposed to the external environment. The guard plate connecting portion 1213a can increase the volume of the housing space in the width direction of the motorcycle 100 to prevent the water tank 165 from interfering with the windshield guard 1214.

[0080] Furthermore, viewed along the height of the motorcycle 100, the skid plate connection 1213a overlaps with at least a portion of the filling tube 1652. The skid plate connection 1213a has a through-hole 1213b extending through its two opposite end faces, through which the filling tube 1652 passes and extends out of the accommodating space.

[0081] The above-mentioned arrangement facilitates the provision of a through-hole 1213b on the side guard plate 1213 for the filling pipe 1652 to pass through. When viewed from the width direction of the motorcycle 100, the through-hole 1213b is blocked by the guard plate connection part 1213a or the wind guard plate 1214, which can improve the overall aesthetics of the vehicle.

[0082] like Figure 9As shown, in one implementation, the water bottle 165 also includes a mounting structure 1654 connected to the bottle body 1651. The mounting structure 1654 is located on the front side of the bottle body 1651 and extends from the bottle body 1651 toward the front of the motorcycle 100. The water bottle 165 is fixedly connected to the frame 11 or the engine 151 through the mounting structure 1654.

[0083] Specifically, the mounting structure 1654 is a plate-shaped structure and is integrally formed with the pot body 1651.

[0084] Furthermore, the water bottle 165 has a water bottle sidewall 1655 facing the wind guard 1214, and a reinforcing rib 1655a is provided on the water bottle sidewall 1655. The extending direction of the reinforcing rib 1655a is not parallel to the height direction of the motorcycle 100.

[0085] In this embodiment, the extending direction of the reinforcing rib 1655a is parallel to the length direction of the motorcycle 100.

[0086] In one implementation, the water bottle 165 is securely connected to the frame 11 or the engine 151 by at least two fasteners. The at least two fasteners are distributed along the height direction of the motorcycle 100 and pass through the mounting structure 1654.

[0087] It should be noted that the mounting structure 1654 is only set on the front side of the kettle 165. When the lid 1653 is rotated, the kettle body 1651 is affected by the torsional force of the rotating lid 1653, and the mounting structure 1654 is easily deformed by the force.

[0088] With the above arrangement, the extension direction of the reinforcing rib 1655a is basically perpendicular to the distribution direction of at least two fasteners, which makes the overall structural strength of the kettle 165 higher.

[0089] In one implementation, the filling pipe 1652 includes a first pipe 1652a and a second pipe 1652b extending toward the rear and upper part of the motorcycle 100. The first pipe 1652a is connected to the pot body 1651 through the second pipe 1652b, defining a reference plane 104 perpendicular to the height direction of the motorcycle. The extension direction of the first pipe 1652a forms a first pipe angle γ with the reference plane 104, and the extension direction of the second pipe 1652b forms a second pipe angle δ with the reference plane 104. The first pipe angle γ is greater than the second pipe angle δ.

[0090] Specifically, at least a portion of the first pipe 1652a passes through the through-port 1213b and extends beyond the accommodating space. The end of the first pipe 1652a opposite to the second pipe 1652b forms a filling port for coolant to enter. Since the included angle γ of the first pipe is greater than the included angle δ of the second pipe, the height of the filling port above the ground is raised to facilitate the filling of coolant into the reservoir 165.

[0091] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
