Description

Technical Field

[0001] The present application relates to the field of vehicle technology, and in particular to a motorcycle. Background Art

[0002] Traditional low-cylinder engines (such as single-bar, double-bar, triple-bar, etc.) rely on naturally aspirated operation, and the intake volume depends entirely on the air filter opening to absorb air, and the engine performance cannot be better utilized.

[0003] For large-displacement, multi-cylinder engine models, a front-end ram air intake is generally used to increase the intake volume. However, due to the compact space and limited layout in the front of the motorcycle, the front-end air intake is greatly restricted by the various electrical components on the head of the motorcycle. Therefore, how to further increase the intake efficiency of the front-end ram air intake is an urgent problem to be solved in the design and research of large-displacement motorcycles. Summary of the Invention

[0004] In order to address the deficiencies of the prior art, the present application aims to provide a motorcycle with high air intake efficiency.

[0005] To achieve the above objectives, this application adopts the following technical solutions:

[0009] Furthermore, the air inlet cross-sectional area of ​​the first air inlet gradually decreases along the distribution direction from the thick-walled part to the lamp housing.

[0010] Furthermore, the maximum air intake cross-sectional area of ​​the first air intake is S1, and a transverse plane perpendicular to the front-rear direction of the motorcycle is defined. The projected area of ​​the first air intake along the front-rear direction of the motorcycle on the transverse plane is defined as S2, and the ratio of S1 to S2 is set to be greater than or equal to 0.8 and less than or equal to 1.2.

[0011] Furthermore, the motorcycle also includes a body cover, which is at least partially arranged around the headlight; the air intake assembly also includes a second air intake pipe, one end of the second air intake pipe is connected to the air filter, and the other end of the second air intake pipe is provided with a second air intake port, which is arranged on the body cover.

[0016] The above-mentioned motorcycle increases the number of air intakes by arranging air intakes on the headlights, and finally introduces a large amount of air into the air filter through multiple guide transfers, ensuring that air fully enters the entire air intake, thereby increasing the air intake volume of the air filter and further improving the combustion efficiency of the engine.

[0025] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the specific implementation of the present application will be clearly and completely described below in conjunction with the drawings in the implementation of the present application.

[0026] like Figure 1 and Figure 2 A motorcycle 100 is shown, comprising a frame 11, a body panel 12, a running assembly 13, a power assembly 14, an air intake assembly 15, and a lighting assembly 16. The frame 11 forms the basic framework of the motorcycle 100 and is used to support the other components of the motorcycle 100. The frame 11 includes a main frame 111 and a front bracket 112 located in front of the main frame 111. The main frame 111 is the core load-bearing frame 11 of the motorcycle 100 and is used to support the main components of the motorcycle 100. The front bracket 112 is primarily used to support some components at the front of the motorcycle 100. The body panel 12 is at least partially disposed on the frame 11 and is used to protect the internal components of the motorcycle 100. The running assembly 13 is used to achieve movement of the motorcycle 100 and is at least partially located below the frame 11. The power assembly 14 is used to provide power to the motorcycle 100 and is transmission-connected to the running assembly 13. The air intake assembly 15 is used to provide air for the combustion of fuel in the power assembly 14. It is connected to the power assembly 14 and includes an air filter 151. Air filter 151 is located below the fuel tank of the motorcycle 100 and is fixedly connected to the main frame 111. Outside air passes through air filter 151 and enters the power assembly 14 to participate in the combustion of the fuel. The lighting assembly 16 is used to provide illumination in environments with low lighting conditions. It is fixedly connected to the front bracket 112 and includes a headlight 161 that is at least partially positioned forward of the front bracket 112. The motorcycle 100 also includes a saddle assembly 17 for seating the rider. Air filter 151 is positioned forward of saddle assembly 17. Air filter 151 is at least partially positioned rearward of headlight 161 and is located on the main frame 111 at one end proximal to the headlight 161. When viewed along the length of the motorcycle 100, air filter 151 and headlight 161 at least partially overlap. In order to clearly illustrate the technical solution of the present invention, the following is also defined: Figure 1It is understood that the length direction in the embodiment of the present application refers to the front-to-back direction of the motorcycle 100, the width direction refers to the left-to-right direction of the motorcycle 100, and the height direction refers to the up-down direction of the motorcycle 100.

[0027] like Figure 3 、 Figure 4 and Figure 5 As shown, as an implementation, a headlamp 161 includes a lamp housing 1611, which is used to mount and protect the various components of the headlamp 161. The lamp housing 1611 includes a lampshade 1611a and a lamp shell 1611b located behind the lampshade 1611a. The lampshade 1611a is fixedly connected to the lamp shell 1611b and defines a receiving space 1611c. The headlamp also includes a light-emitting element 1612 and other related circuit board components. The light-emitting element 1612 and the circuit board components are both disposed within the receiving space 1611c. The lamp shell 1611b is fixedly connected to the front bracket 112. The lampshade 1611a and the lamp housing 1611b can be glued together. This connection method can reduce the number of connectors, thereby improving the assembly efficiency of the lampshade 1611a and the lamp housing 1611b, and can also seal the connection between the lampshade 1611a and the lamp housing 1611b to prevent air from entering the lamp housing 1611 and fogging the inner wall of the lamp housing 1611, resulting in poor lighting effect of the headlamp 161 and posing a safety hazard to the driver during driving, thereby improving the lighting effect of the headlamp 161. The lampshade 1611a and the lamp housing 1611b can also be connected in other ways, such as bolt connection. Specifically, Figure 5As shown, the lamp housing 1611 further includes a thick-walled member 1611d. As a specific embodiment, in this application, the thick-walled member 1611d is disposed outside the lampshade 1611a. Furthermore, the thick-walled member 1611d is disposed in front of the lampshade 1611a and is integrally formed with the lampshade 1611a. It is understood that the thick-walled member 1611d is configured as a light-transmitting material, which can act as a reflector, not only effectively blocking the light inside the headlamp 161 to prevent light scattering and leakage, but also improving the focus and brightness of the light beam. In the prior art, the thick-walled part 1611d is usually arranged inside the accommodating space 1611c set between the lamp housing 1611b and the lampshade 1611a, and is at least partially located between the light-emitting part 1612 and the lampshade 1611a. The thick-walled part 1611d is generally arranged to be fixedly connected to the lampshade 1611a, and an installation gap of more than 1.5 mm needs to be reserved between the thick-walled part 1611d and the lampshade 1611a to avoid relative wear between the thick-walled part 1611d and the lampshade 1611a due to bumps during vehicle driving, thereby causing damage to the headlamp 161. However, this arrangement method also easily leads to a larger volume of the headlamp 161, which is not conducive to the arrangement of the headlamp 161. Therefore, in this embodiment, the thick-walled member 1611d and the lampshade 1611a are integrally formed, forming a single unit. This eliminates the need for a gap between the thick-walled member 1611d and the lampshade 1611a, reducing the space occupied by the thick-walled member 1611d and the lampshade 1611a. This also simplifies the installation process of the headlamp 161 and improves the assembly efficiency of the headlamp 161. This reduces the overall dimensions of the headlamp 161, providing space for the installation of other components of the motorcycle 100 and thereby improving the compactness of the headlamp 161. Furthermore, the thick-walled member 1611d refracts and reflects light emitted by the light-emitting element 1612, thereby changing the direction and angle of light propagation. Furthermore, by rationally designing the shape and curved surface of the thick-walled member 1611d, light is effectively focused and reflected within the headlamp 161, increasing the brightness and focusing effect of the beam, thereby effectively enhancing the lighting effect of the headlamp 161. The thick-walled part 1611d and the lampshade 1611a are fixedly connected through an integrated molding process, which can also improve the structural strength of the lampshade 1611a, so that the lampshade 1611a can provide protection for the internal parts of the headlamp 161, avoiding damage to the internal parts of the headlamp 161 when the motorcycle 100 is hit from the front, thereby improving the reliability and service life of the headlamp 161.

[0028] like Figure 5As shown, the thick-walled member 1611d is mainly used to refract the light emitted by the light-emitting member 1612 to improve the lighting effect of the headlight 161. Generally, the thick-walled member 1611d is set to a solid transparent material, and the lampshade 1611a is mainly used to provide support and protection for the headlight 161. Therefore, the wall thickness D1 of the thick-walled member 1611d in the width direction of the motorcycle 100 is greater than the wall thickness D2 of the lampshade 1611a in the width direction of the motorcycle 100, thereby making the wall thickness distribution of the lampshade 1611a uneven. If processed according to the ordinary injection molding process, it is easy to cause accommodation defects such as component shrinkage. Therefore, the thick-walled member 1611d and the lampshade 1611a in this application are injection molded by secondary injection molding. Specifically, during the processing, the thick-walled member 1611d with a thicker wall thickness is first injection molded. After the initial production is completed, the lampshade 1611a with a thinner wall thickness is injection molded, thereby completing the production of the entire lampshade 1611a component. Through the above arrangement, secondary injection molding can optimize the production process of lampshade 1611a, avoid problems with lampshade 1611a during the production process, thereby improving the production efficiency of lampshade 1611a and reducing the production cost of lampshade 1611a. It should be noted that since thick-walled member 1611d is configured as a solid structure, the wall thickness of thick-walled member 1611d is the maximum thickness of thick-walled member 1611d in the width direction of motorcycle 100, which is referred to as D1 in the figure. The wall thickness of lampshade 1611a refers to the distance between the inner and outer walls of lampshade 1611a in the width direction of motorcycle 100, which is referred to as D2 in the figure.

[0029] like Figure 6 As shown, as an implementation, the air intake assembly 15 further includes a first air intake pipe 152 and a first air intake port 153. One end of the first air intake pipe 152 is connected to the air filter 151, and the other end of the first air intake pipe 152 is connected to the first air intake port 153, so as to achieve communication between the first air intake port 153 and the air filter 151. As an optional embodiment, the first air intake port 153 is at least partially disposed at the front end of the motorcycle 100 and faces the front end of the motorcycle 100, so as to facilitate rapid air intake while the motorcycle 100 is moving. Specifically, the first air inlet 153 is at least partially composed of the headlight 161, that is, the first air inlet 153 is arranged on the headlight 161, and the first air inlet 153 is surrounded by the headlight 161, so that the direction of the first air inlet 153 can be set together with the headlight 161 to face the front of the motorcycle 100. Furthermore, the air intake direction of the first air inlet 153 is basically opposite to the light irradiation direction of the headlight 161, so as to form an air diversion during the driving of the motorcycle 100 and facilitate the air intake of the air filter 151. The first air inlet 153 is arranged on the headlight 161 and can also improve the appearance performance of the motorcycle 100.

[0030] like Figure 7Specifically, the first air inlet 153 is primarily formed by a portion of the headlamp 161's housing 1611b, a lampshade 1611a, and a thick-walled member 1611d surrounding the housing 1611b. In this application, at least portions of the lampshade 1611a and the thick-walled member 1611d are configured as an annular structure. The light-emitting element 1612 and other electronic components of the headlamp 161 are arranged around the first air inlet 153 within a receiving space 1611c formed by the housing 1611b and the lampshade 1611a. As can be appreciated, the primary light-emitting area of ​​the headlamp 161 is circular. As can be appreciated, when air is drawn into the first air inlet 153, air flows sequentially through the thick-walled member 1611d, the lampshade 1611a, and the housing 1611b. As previously mentioned, since the thick-walled member 1611d is positioned outside the lampshade 1611a in this application, this arrangement effectively extends the air intake length of the first air inlet 153. Furthermore, the intake cross-sectional area or circumference of the first air inlet 153 gradually decreases along the intake direction. This configuration not only effectively increases the intake area, but also allows for initial compression of the air within the first intake pipe 152, increasing air flow rate and further improving intake efficiency. It should be explained that the "intake cross-sectional area" refers to the cross-sectional area of ​​the three different portions of the aforementioned air inlet, measured along a transverse plane. As an optional embodiment, a transverse plane 101 perpendicular to the length of the motorcycle 100 is defined, and the projections of the light-emitting element 1612 and the first air inlet 153 onto the transverse plane 101 along the length of the motorcycle 100 are both substantially circular. The light-emitting elements 1612 are evenly distributed around the first air inlet 153. Specifically, the projections of the first air inlet 153 and the light-emitting elements 1612 along the length of the motorcycle 100 onto the transverse plane 101 form substantially concentric circles. This allows the first air inlet 153 to be positioned without affecting the illumination of the headlamp 161, thereby improving the space utilization of the lighting assembly 16 and enhancing the appearance of the motorcycle 100. The maximum air inlet cross-sectional area of ​​the first air inlet 153 is defined as S1, and the projection area of ​​the first air inlet 153 along the length of the motorcycle 100 onto the transverse plane 101 is defined as S2. The ratio of S1 to S2 is set to be greater than or equal to 0.8 and less than or equal to 1.2. Furthermore, the ratio of S1 to S2 is set to be greater than or equal to 0.9 and less than or equal to 1.1. In this embodiment, the ratio of S1 to S2 is set to 1. Through the above setting, when the ratio of S1 to S2 is set to 1, the maximum air intake surface of the first air inlet 153 is the projection of the first air inlet 153 on the transverse plane 101 along the length direction of the motorcycle 100, that is, the first air inlet 153 is always on the windward side during the driving process of the motorcycle 100. At this time, the first air inlet 153 is in a state of maximum air intake, thereby ensuring that the air intake efficiency of the first air inlet 153 can always be at the highest, thereby improving the working efficiency of the air filter 151.

[0031] like Figure 6 As shown, the air intake assembly 15 further includes a second air intake pipe 154 and a second air intake port 155. One end of the second air intake pipe 154 is connected to the air filter 151, and the other end of the second air intake pipe 154 is connected to the second air intake port 155. The second air intake port 155 is at least partially located at the front end of the motorcycle 100 and at least partially below the first air intake port 153. The air intake direction of the second air intake port 155 is substantially the same as that of the first air intake port 153. As a possible embodiment, the body panel 12 is at least partially located at the front end of the motorcycle 100 and is arranged around the headlight 161. The second air intake port 155 can be located on the body panel 12 located at the front end of the motorcycle 100 and covered by the body panel 12. The second air intake pipe 154 is at least partially located below the first air intake pipe 152 and extends in a direction substantially consistent with that of the first air intake pipe 152. As a specific embodiment, the first air intake pipe 152 and the second air intake pipe 154 can be merged and connected between the headlight 161 and the air filter 151, that is, the first air intake pipe 152 and the second air intake pipe 154 are merged into one pipe in front of the air filter 151, thereby improving the structural compactness of the air intake assembly 15 and improving the space utilization of the air intake assembly 15.

[0032] like Figure 7As shown, in the prior art, air intake for air filter 151 is primarily achieved through natural aspiration and ram air intake. The former involves drawing air solely through the openings of air filter 151; the latter, through a rationally designed ram air intake duct, converts the dynamic pressure of the high-speed oncoming airflow into static pressure, thereby increasing the intake pressure of intake assembly 15. In the present application, the first and second intake ducts 152, 154 extend substantially along the length of motorcycle 100, and the intake direction of the first and second air inlets 152, 154 is opposite to the direction of travel of motorcycle 100. Therefore, the speed of motorcycle 100 can be utilized to generate ram air during travel, thereby increasing the intake volume of air filter 151. In the prior art, due to limited frontal space, only the second air inlet 155 and the second intake duct 154 are permitted. Increasing the intake volume of air filter 151 by increasing the inner diameter of the air inlet would occupy space for other components and would also make motorcycle 100 bulky. In the present application, based on the existing air intake, the space provided for the headlamp 161 is fully utilized to add an additional air intake to the headlamp 161. This significantly increases the air intake volume of the air filter 151, further enhancing the stamping efficiency, enabling more complete combustion of the fuel in the power assembly 14, and improving the combustion efficiency of the fuel in the power assembly 14. Through the above arrangement, by utilizing the space provided for the headlamp 161, the number of air intakes is increased without increasing the overall size of the motorcycle 100, thereby increasing the air intake volume of the air filter 151, thereby improving the air intake effect of the air filter 151 and, in turn, the operating efficiency of the power assembly 14.

[0033] It is understandable that the number of first air inlets 153 can be set to be greater than or equal to 1, and the number of second air inlets 155 can also be set to be greater than or equal to 1. As a preferred embodiment, in the present application, since the first air inlets 153 are provided on the headlight 161 and the first air inlet 153 is at least partially surrounded by the headlight 161, the number of lamp bodies of the headlight 161 and the number of the first air inlets 153 are set to be substantially the same. In the present application, the number of the headlight 161, the first air inlets 153, and the second air inlets 155 are all set to two. A longitudinal plane 102 is defined that is perpendicular to the width direction of the motorcycle 100 and passes through the center of the width of the motorcycle 100. The headlight 161 and the first air inlets 153 are symmetrical relative to the longitudinal plane 102 along the width direction of the motorcycle 100. Furthermore, the number of the second air inlets is set to be basically the same as the number of the first air inlets, and the second air inlets 155 are also symmetrical about the longitudinal plane 102 along the width direction of the motorcycle, so that the air intake of the air filter 151 can be increased without increasing the overall size of the motorcycle 100, avoiding the motorcycle 100 from having a complex and bulky structure, while also making the wind resistance on the left and right sides of the vehicle basically the same, effectively improving the vehicle's driving stability. First air inlet 153, second air inlet 155, second air intake pipe 154.

[0034] like Figure 6 and Figure 7 As shown, the first and second air intake ducts 152, 154 are located substantially inside the body panel 12. When viewed across the width of the motorcycle 100, the second air intake port 155 is at least partially located below the first air intake port 153. The body panel 12 and the air intake ducts at least partially overlap. It should be understood that the "inner side of the body panel 12" referred to above refers to the side of the body panel 12 closer to the longitudinal plane 102 along the width of the motorcycle 100. This arrangement protects the first and second air intake ducts 152, 154 from being exposed. This prevents flying sand and gravel from colliding with the first and second air intake ducts 152, 154 during operation, potentially rupturing them and reducing the air intake efficiency of the air filter 151. In addition, a connection point may be provided on the vehicle body cover 12 to improve the connection strength between the first air intake pipe 152 and the second air intake pipe 154 to prevent the first air intake pipe 152 and the second air intake pipe 154 from falling off during the driving of the motorcycle 100 .

[0035] like Figure 8As shown, in this embodiment, the first air intake pipe 152 includes a guide pipe 1521 and a connecting pipe 1522. The guide pipe 1521 and the connecting pipe 1522 are connected to each other. The guide pipe 1521 is fixedly connected to the first air intake port 153, and the connecting pipe 1522 is fixedly connected to the second air intake pipe 154. Through the above-mentioned arrangement, the guide pipe 1521 is mainly used to change the arrangement direction of the first air intake pipe 152 to avoid the front bracket 112 of the motorcycle 100 and avoid affecting the arrangement of other parts. The connecting pipe 1522 is mainly used to connect the first air intake pipe 152 and the second air intake pipe 154, so that the first air intake pipe 152 is connected to the air filter 151 through the second air intake pipe 154, thereby avoiding the need to set an additional air inlet on the air filter 151, so that there is no need to make additional modifications to the air filter 151, so that the first air intake pipe 152 and the second air intake pipe 154 can be adapted to most air filters 151, thereby improving the versatility of the first air intake pipe 152 and the second air intake pipe 154, reducing the cost of the motorcycle 100, and improving the assembly efficiency of the motorcycle 100.

[0036] Furthermore, guide tube 1521 is constructed of rubber and has an interference fit with first air inlet 153 and an interference fit with connecting tube 1522. This configuration facilitates the orientation of guide tube 1521 by making it rubber. Furthermore, the rubber material allows for an interference fit between guide tube 1521 and first air inlet 153 or connecting tube 1522, thereby reducing air loss in first air inlet 152 and improving the air intake efficiency of air filter 151. Furthermore, the rubber material also requires lower tolerances for guide tube 1521, facilitating its fabrication.

[0037] As an embodiment, a first clamping portion 1611e is provided on the lamp housing 1611b, a first clamping hole 1521a is provided at one end of the guide tube 1521, and the first clamping portion 1611e and the first clamping hole 1521a are clamped together. A second clamping portion 1521b is provided at the other end of the guide tube 1521, and a second clamping hole 1522a is provided at one end of the connecting tube 1522, and the second clamping portion 1521b and the second clamping hole 1522a are clamped together. Furthermore, a third clamping hole 1522b is provided at the other end of the connecting tube 1522, and a third clamping portion 1541 is provided on the second air intake pipe 154, and the third clamping portion 1541 and the third clamping hole 1522b are clamped together. With the above arrangement, the clamping fixing method can facilitate the installation of the guide tube 1521 and the connecting tube 1522, thereby simplifying the installation process and improving the assembly efficiency of the motorcycle 100. In the embodiment of the present application, the clamping connection is merely a preferred embodiment; other fixing methods, such as bolting or gluing, may also be used to connect the guide tube 1521 and the connecting tube 1522, and the connecting tube 1522 and the second air intake pipe 154. Furthermore, the second air intake pipe 154 is provided with a positioning portion 1542, which abuts against the connecting tube 1522. Thus, during the installation process of the connecting tube 1522 and the second air intake pipe 154, the positioning portion 1542 can provide a positioning function, thereby improving the assembly efficiency of the connecting tube 1522.

[0038] Furthermore, an air intake grille 1531 is provided on the first air intake 153. When the first air intake 153 is provided on the headlight 161, a corresponding air intake grille 1531 is also provided on the headlight 161. The air intake grille 1531 prevents debris from entering the first air intake pipe 152 during the intake of air through the first air intake 153, thereby preventing the first air intake pipe 152 from being clogged and thus affecting the air intake efficiency of the air filter 151 and, consequently, the operation of the power assembly 14. Furthermore, an air intake grille 1531 may also be provided on the second air intake 155 to further reduce the probability of debris entering the air filter 151.
