Description

Technical Field

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

[0002] Currently, motorcycle cooling systems typically include a radiator, a fan fixed behind the radiator, and a shroud behind the fan. The shroud usually covers the upper area behind the fan, while the lower area behind the fan serves as the air outlet. In practical use, it has been found that when the vehicle is idling or traveling at low speeds, the airflow exhausted by the fan is easily affected by heat radiation from the engine exhaust manifold located behind the air outlet, causing a significant increase in airflow temperature. If this heated airflow flows over the rider's legs or torso, it can affect riding comfort. Utility Model Content

[0003] In view of this, this application provides a motorcycle with better riding comfort.

[0004] This application provides an embodiment of a motorcycle, including a frame, body panels, a running gear system, a power system, and a cooling system. The body panels at least partially cover the frame and include protective plates located on the left and / or right sides of the frame. The protective plates have cooling vents. The running gear system is at least partially located under the frame. The power system is supported by the frame and includes an engine and an exhaust manifold connected to the engine. The cooling system includes a radiator and a cooling fan. The radiator is supported by the frame, and the cooling fan is located behind the radiator and the exhaust manifold. The cooling fan has a rotation axis. The cooling system includes a main windshield plate located between the cooling fan and the exhaust manifold, and below the rotation axis of the cooling fan. Viewed along the rotation axis of the cooling fan, the main windshield plate and the exhaust manifold at least partially overlap. The cooling vents are located to the side of the main windshield plate, and no part of the exhaust manifold is located between the main windshield plate and the cooling vents.

[0005] In some alternative embodiments, the main baffle plate has a baffle base plate extending toward the cooling fan on the side away from the rotation axis of the cooling fan. The cooling fan includes fan blades. When viewed along the rotation axis of the cooling fan, the baffle base plate is at least partially located outside the outer contour of the area covered by the fan blades when they rotate.

[0006] In some optional embodiments, the windshield main board has a windshield side plate on the side along the width direction of the frame, and the side of the windshield side plate facing the cooling fan has an air guide groove, which is used to guide part of the airflow discharged from the radiator or cooling fan to the heat dissipation port.

[0007] In some alternative embodiments, the air guide slits extend upward and are inclined relative to the horizontal plane, with the upper end of the air guide slits being further away from the main baffle than the lower end.

[0008] In some optional embodiments, a first fixing part is provided on the side of the windshield main board away from the windshield base plate, and a second fixing part is provided on the side of the windshield base plate away from the windshield main board. Both the first fixing part and the second fixing part are detachably connected to the cooling fan.

[0009] In some alternative embodiments, the heat dissipation system includes an air guide shroud connected to and located above the rotation axis of the cooling fan, with the air guide shroud and the main air deflector spaced apart along the height of the vehicle frame.

[0010] In some optional embodiments, the cooling fan is an axial fan, which includes fan blades and a casing. The casing is located behind the fan blades. When viewed from back to front along the rotation axis of the cooling fan, the casing covers the center of the area covered by the fan blades when they rotate. The air guide covers the upper part of the area covered by the fan blades when they rotate. The lower part of the air guide overlaps with the upper part of the casing, or the lower edge of the air guide connects with the upper edge of the casing. The baffle plate covers the lower part of the area covered by the fan blades when they rotate. The upper part of the baffle plate overlaps with the lower part of the casing, or the upper edge of the baffle plate connects with the lower edge of the casing.

[0011] In some optional embodiments, the air guide includes a main body and a side air guide. The main body is located on the side of the cooling fan away from the radiator, and the side air guide is located on the side of the main body along the width direction of the frame. The side air guide includes a first flat section, a bent section, and a second flat section. The first flat section is connected to the main body, and the bent section is connected to the first flat section and the second flat section. The end of the second flat section away from the bent section extends toward the heat dissipation vent. The side air guide is used to guide part of the airflow flowing through the first flat section to flow through the bent section and the second flat section toward the heat dissipation vent.

[0012] In some alternative embodiments, the air guide includes a main body and a top air guide. The main body is located on the side of the cooling fan away from the radiator, and the top air guide is located above the main body along the height direction of the vehicle frame. When viewed along the rotation axis of the cooling fan, the highest point of the top air guide is located above the cooling fan. When viewed along the height direction of the vehicle frame, a portion of the top air guide overlaps with the cooling fan.

[0013] In some alternative embodiments, the highest end of the top air guide is provided with an air outlet, which, when viewed along the height of the vehicle frame, at least partially overlaps with the cooling fan.

[0014] By placing a baffle plate below the rotating axis of the cooling fan and positioning it between the cooling fan and the exhaust manifold, the airflow exhausted from the cooling fan can be effectively guided to the heat dissipation vents located on the guard plate. This structure reduces the airflow that comes into contact with the high-temperature exhaust manifold, reduces the degree to which the airflow is affected by heat radiation, thereby reducing the temperature rise of the airflow blowing towards the rider's legs and torso area and improving riding comfort.

Detailed Implementation

[0016] To further illustrate the technical means and effects adopted by this application to achieve the intended purpose, the following description, in conjunction with the accompanying drawings and embodiments, is provided. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0017] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0018] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the embodiments and features described below can be combined with each other.

[0019] Please see Figure 1 A motorcycle 100 includes a frame 11, a body panel 12, a running system 13, a power system 14, and a cooling system 15. The body panel 12 covers at least part of the frame 11, the running system 13 is at least partly located under the frame 11, and the power system 14 and the cooling system 15 are supported by the frame 11.

[0020] For ease of description, this application defines the directions of front, back, left, right, up, and down. The front-back direction refers to the length direction of the motorcycle frame 11, the left-right direction refers to the width direction of the motorcycle frame 11, and the up-down direction refers to the height direction of the motorcycle frame 11. In this embodiment, the directions of front, back, left, right, up, and down are based on the motorcycle 100 traveling on a level road surface, not on a sloping road surface.

[0021] The walking system 13 includes a front wheel 131 located in front of the motorcycle 100 and a rear wheel 132 located behind the motorcycle 100, and the front wheel 131 and the rear wheel 132 are respectively rotatably connected to the frame 11.

[0022] The body panel 12 includes a protective plate 121 located at the front right side of the frame 11. In other embodiments, the body panel 12 includes a protective plate (not shown) located at the front left side of the frame 11. In other embodiments, the body panel 12 includes protective plates located at the front left and front right sides of the frame 11. The protective plate 121 is provided with heat dissipation vents 1211.

[0023] Please see Figure 1 and Figure 2 In some embodiments, the frame 11 includes a first frame 111, a second frame 112, and a third frame 113. The second frame 112 is connected to the rear of the first frame 111, and the third frame 113 is disposed below and connected to the first frame 111. A receiving space 114 is formed between the third frame 113 and the first frame 111. The power system 14 includes an engine 141 and an exhaust manifold 142 connected to the engine 141. The engine 141 and the exhaust manifold 142 are disposed within the receiving space 114 and connected to the third frame 113.

[0024] Please see Figure 2 and Figure 3 In some embodiments, the cooling system 15 includes a radiator 151, a cooling fan 152, and a baffle plate 153. The radiator 151 is supported by the vehicle frame 11, and is fixedly connected to the vehicle frame 11. In other embodiments, the radiator 151 is fixedly connected to the body panel 12.

[0025] A cooling fan 152 is located behind and connected to the radiator 151, and an exhaust manifold 142 is located behind the cooling fan 152. The cooling fan 152 has a rotation axis O. A baffle plate 153 is located below the rotation axis O of the cooling fan 152 and between the cooling fan 152 and the exhaust manifold 142. Viewed from front to back, the baffle plate 153 at least partially overlaps with the exhaust manifold 142. The baffle plate 153 is used to guide a portion of the airflow exhausted from the cooling fan 152 through the heat dissipation port 1211. No part of the exhaust manifold 142 is located between the baffle plate 153 and the heat dissipation port 1211. It is understood that "any part" of the exhaust manifold 142 refers to any part of the main structure of the exhaust manifold 142 used for exhaust function, excluding components connected to the main structure for connecting or decorative purposes. By placing a baffle plate 153 below the rotation axis O of the cooling fan 152 and positioning it between the cooling fan 152 and the exhaust manifold 142, the airflow exhausted from the radiator 151 or the cooling fan 152 can be effectively guided to the heat dissipation vent 1211 of the guard plate 121. This structure reduces the airflow in contact with the high-temperature exhaust manifold 142, reducing the degree to which the airflow is affected by heat radiation, thereby reducing the temperature rise of the airflow blowing towards the rider's legs and torso. The guiding effect of the baffle plate 153 makes the cooling airflow more concentrated and discharged from the heat dissipation vent 1211, optimizing the airflow distribution path of the cooling system 15. At the same time, this design improves the discomfort caused by the impact of hot airflow during riding while maintaining the original heat dissipation performance, thus improving riding comfort.

[0026] Please see Figure 3 and Figure 4 In some embodiments, when viewed from the rear of the heat sink 151 towards the front, the cooling fan 152 rotates counterclockwise. The airflow exhausted from the heat sink 151 or the cooling fan 152 flows in the upper left, lower left, upper right, and lower right directions.

[0027] Please refer to the attached document. Figure 1 The right side body panel 12 is provided with a first air outlet 122 and a second air outlet 123, the bottom body panel 12 is provided with a third air outlet 124, and the left side (not shown) body panel 12 is provided with a fourth air outlet and a fifth air outlet.

[0028] The airflow to the upper right is mainly discharged from the first air outlet 122, the second air outlet 123 of the right side body panel 12 and the heat dissipation vent 1211 of the right side guard plate 121.

[0029] The airflow to the upper left is mainly discharged from the fourth and fifth air outlets of the left body panel 12 and the heat dissipation vent 1211 of the left side guard plate 121.

[0030] The airflow to the lower right is mainly discharged from the third air outlet 124 of the bottom body panel 12, the first air outlet 122 and the second air outlet 123 of the right body panel 12, and the heat dissipation vent 1211 of the right side guard plate 121.

[0031] The airflow to the lower left is mainly discharged from the third air outlet 124 of the bottom body panel 12, the fourth and fifth air outlets of the left body panel 12, and the heat dissipation vent 1211 of the left side guard plate 121.

[0032] Please see Figure 3 and Figure 5 In some embodiments, the wind deflector 153 has a wind deflector base plate 1531 extending toward the cooling fan 152 on the side away from the rotation axis O of the cooling fan 152. The cooling fan 152 includes fan blades 1521. When viewed along the rotation axis O of the cooling fan 152, the wind deflector base plate 1531 is at least partially located outside the outer contour of the area covered by the fan blades 1521 when they rotate.

[0033] The design of the windshield base plate 1531 extending towards the cooling fan 152, combined with the arrangement of the lowest point of the windshield base plate 1531 outside the projection area of ​​the fan blades 1521, optimizes airflow guidance. This structure expands the guiding range of the main windshield plate 153 for the exhaust air of the cooling fan 152, allowing more airflow to be effectively directed to the heat dissipation vents 1211 of the guard plate 121. The extended portion of the windshield base plate 1531 helps reduce disordered airflow diffusion below the fan blades 1521, improving airflow efficiency. At the same time, this layout, while maintaining smooth airflow discharge, helps to further block the impact of heat radiation from the exhaust manifold 142 on the cooling airflow, thereby improving the overall airflow efficiency of the cooling system 15 and improving thermal comfort in the riding area.

[0034] In some embodiments, the windshield main plate 153 has a windshield side plate 1532 on its side along the width direction of the frame 11. The side plate 1532 facing the cooling fan 152 has an air guide groove C1, which guides part of the airflow discharged from the radiator 151 or the cooling fan 152 to the heat dissipation port 1211. By guiding the lateral airflow through the air guide groove C1, the airflow that would otherwise diffuse randomly is directed more concentratedly to the heat dissipation port 1211 of the guard plate 121. The windshield side plate 1532 reduces the lateral dispersion of airflow along the width direction of the frame 11, and the structure of the air guide groove C1 helps to form a directional airflow channel, improving the airflow guidance efficiency.

[0035] In some embodiments, multiple air guide slots C1 are provided, and they are arranged substantially parallel to each other. Multiple substantially parallel air guide slots C1 can form an orderly airflow channel array, which can reduce airflow turbulence in the area of ​​the windshield side panel 1532, allowing the airflow to be guided more smoothly to the heat dissipation vent 1211. At the same time, the substantially parallel arrangement of the air guide slots C1 helps maintain the consistency of airflow direction, avoiding interference between airflows from different directions, thereby improving the airflow guiding efficiency.

[0036] In some embodiments, the air guide slot C1 extends upward and is inclined relative to the horizontal plane. The upper end of the air guide slot C1 is further away from the wind deflector main board 153 than its lower end. By designing the upper end of the air guide slot C1 to be inclined outward, the airflow can be guided to flow towards the heat dissipation port 1211 in an upward direction, thereby enhancing the natural convection effect by utilizing the upward characteristics of the airflow.

[0037] In some embodiments, the main baffle plate 153 has a first fixing part 1533 on the side away from the baffle base plate 1531, and the baffle base plate 1531 has a second fixing part 1534 on the side away from the main baffle plate 153. Both the first fixing part 1533 and the second fixing part 1534 are detachably connected to the cooling fan 152. Specifically, both the first fixing part 1533 and the second fixing part 1534 are fixed to the cooling fan 152 by fastening bolts.

[0038] In some embodiments, two first fixing portions 1533 are provided at intervals.

[0039] In some embodiments, the windshield main board 153, the windshield base plate 1531, the first fixing part 1533 and the second fixing part 1534 are integrally formed by sheet metal bending, thereby improving the connection strength and overall structural stability between the windshield main board 153, the windshield base plate 1531, the first fixing part 1533 and the second fixing part 1534.

[0040] Please see Figure 3 and Figure 6 In some embodiments, the heat dissipation system 15 includes an air guide shroud 154, which is connected to the cooling fan 152 and located above the rotation axis O of the cooling fan 152. The air guide shroud 154 and the wind deflector 153 are spaced apart along the height direction of the frame 11. The upper air guide shroud 154 guides the airflow above the fan, while the wind deflector 153 guides the airflow below the fan, thereby achieving independent guidance of the heat dissipation airflow.

[0041] The cooling fan 152 is an axial fan. The airflow discharged from the cooling fan 152 has a spiral outward tendency around its rotation axis O. It also includes a cover 1522, which is located behind the fan blades 1521. Observing from back to front along the rotation axis O of the cooling fan 152, the cover 1522 covers the center of the area covered by the fan blades 1521 when they rotate. The air guide shroud 154 covers the upper part of the area covered by the fan blades 1521 when they rotate. The lower part of the air guide shroud 154 overlaps with the upper part of the cover 1522, or the lower edge of the air guide shroud 154 is connected to the upper edge of the cover 1522. The wind baffle 153 covers the lower part of the area covered by the fan blades 1521 when they rotate. The upper part of the wind baffle 153 overlaps with the lower part of the cover 1522, or the upper edge of the wind baffle 153 is connected to the lower edge of the cover 1522. With this configuration, when viewed from back to front along the rotation axis O of the cooling fan 152, only the two areas 101 on the left and right sides can expel air when the fan blades 1521 rotate. Since these two areas are relatively close to the heat dissipation vents 1211 of their respective nearest protective plates 121, the airflow thrown outward from these two areas 101 can more easily reach the heat dissipation vents 1211 of the protective plates 121, thus efficiently dissipating hot airflow.

[0042] In some embodiments, the air guide shroud 154 includes a main body 1541, a side air guide 1542, and a top air guide 1543. The main body 1541 is located on the side of the cooling fan 152 away from the heat sink 151, and is mainly used to block part of the airflow discharged from the upper part of the cooling fan 152 and guide it to the side air guide 1542 and the top air guide 1543.

[0043] A side air guide 1542 is provided on the side of the main body 1541 along the width direction of the frame 11, and is used to guide part of the airflow discharged from the upper part of the cooling fan 152 to the heat dissipation vent 1211 on the right side of the motorcycle 100. A top air guide 1543 is provided above the main body 1541 along the height direction of the frame 11, and is used to guide part of the airflow discharged from the upper part of the cooling fan 152 to the fourth and fifth air outlets of the left body panel 12 and the heat dissipation vent 1211 of the left side guard plate 121.

[0044] In some embodiments, the side air guide 1542 includes a first flat section P1, a bent section P2, and a second flat section P3. The first flat section P1 connects to the main body 1541, and the bent section P2 connects the first flat section P1 and the second flat section P3. Viewed along the width direction of the air guide shroud 154, the first flat section P1 and the second flat section P3 have an acute angle, which is used to guide part of the airflow flowing through the first flat section P1 through the bent section P2 and the second flat section P3 to the heat dissipation port 1211. The first flat section P1 is used to rectify the initial airflow, and then the bent section P2 achieves a smooth change in airflow direction. Finally, the second flat section P3 precisely guides the airflow to the heat dissipation port 1211. The bend structure with an acute angle design ensures the efficiency of airflow turning while effectively reducing the risk of airflow separation and vortex generation, allowing the airflow to complete the direction change more smoothly.

[0045] In some embodiments, when viewed along the width direction of the air guide 154, the highest end of the top air guide 1543 is located above the cooling fan 152, and when viewed along the height direction of the frame 11, the highest end of the top air guide 1543 is located within the range of the cooling fan 152, so that the vertical airflow above the cooling fan 152 is intercepted and turned to the side, avoiding disorderly diffusion of airflow.

[0046] In some embodiments, the highest end of the top air guide 1543 is provided with an air outlet C2. When viewed along the height direction of the frame 11, the air outlet C2 partially overlaps with the cooling fan 152, allowing some of the upward airflow to pass directly through the air outlet C2, while the remaining airflow is guided and redirected by the top air guide 1543. This arrangement preserves the natural upward path of the airflow while limiting the disorderly diffusion of the airflow through the controllable air outlet C2.

[0047] Furthermore, those skilled in the art should recognize that the above embodiments are merely illustrative of this application and are not intended to limit this application. Any appropriate changes and variations made to the above embodiments within the essential spirit and scope of this application fall within the scope of this application's disclosure.
