Technical Field

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

[0002] With the development of technology, different types of motor vehicles play a role in different fields. Motorcycles, due to their small size and flexibility, also play an important role in some fields. The rectifier voltage regulator is an important component of motorcycles, used to stabilize the voltage of the motorcycle. However, the current rectifier voltage regulator is usually located in the center of the vehicle body, which makes it difficult for the rectifier voltage regulator to dissipate heat. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this application presents a motorcycle with higher space utilization and better performance by changing the position of the internal structure.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a motorcycle, including a frame; a body panel, at least a portion of which is disposed on the frame; a running gear, including a front wheel and a rear wheel; a suspension assembly, including a front suspension and a rear suspension, wherein the front wheel is connected to the frame via a front suspension and the rear wheel is connected to the frame via a rear suspension; a power system for driving the running gear; a fuel tank, disposed on the frame and located at the front of the frame; a power system, including a battery and a rectifier and voltage regulator for stabilizing voltage; a seat, at least a portion of which is disposed on the body panel; the body panel having a ventilation section; the rectifier and voltage regulator being connected to the fuel tank and located on the side of the fuel tank away from the seat, wherein in a projection plane perpendicular to the length direction of the motorcycle, the projection of the ventilation section on the projection plane coincides with the projection of the rectifier and voltage regulator on the projection plane.

[0005] Furthermore, the ventilation section includes multiple ventilation holes arranged sequentially along the width of the motorcycle.

[0006] Furthermore, the rectifier voltage regulator is provided with an air guide slot, and on a projection surface perpendicular to the length direction of the motorcycle, the projection of the ventilation hole on the projection surface coincides with the projection of the air guide slot on the projection surface.

[0007] Furthermore, the power system also includes a bracket, through which the rectifier and voltage regulator are connected to the oil tank.

[0008] Furthermore, the power system also includes a connector that runs through the rectifier and the bracket to connect the rectifier to the tank.

[0009] Furthermore, the power system also includes a support for reducing vibration, which is positioned between the support and the rectifier voltage regulator.

[0010] Furthermore, multiple connectors are provided, and these connectors are arranged sequentially along the height direction of the motorcycle.

[0011] Furthermore, the power system also includes plugs and wiring harnesses. The plugs are inserted into the side of the rectifier voltage regulator, one end of the wiring harness is connected to the plugs, and the other end of the wiring harness is connected to the engine.

[0012] Furthermore, the body panel includes a body and a panel, the panel and the body are detachably connected, the ventilation unit is disposed on the panel, and in a projection plane perpendicular to the length direction of the motorcycle, the projection of the panel on the projection plane coincides with the projection of the rectifier voltage regulator on the projection plane.

[0013] Furthermore, the suspension assembly also includes a shock absorber connected to the frame and positioned on the side of the frame near the rectifier regulator.

[0014] The advantages of this invention are as follows: the rectifier and voltage regulator are located on the side of the fuel tank away from the seat, at the front of the vehicle.

A ventilation section is provided on the body panel corresponding to the position of the rectifier and voltage regulator, such that at least a portion of the projection of the ventilation section onto the fuel tank coincides with the projection of the rectifier and voltage regulator onto the fuel tank. Therefore, when the motorcycle is in motion, cool outside air can flow through the ventilation section to the surface of the rectifier and voltage regulator, cooling it and ensuring its normal operation. Simultaneously, the body panel also protects the rectifier and voltage regulator from damage caused by external impacts.

[0062] The accompanying drawings, which are incorporated in and form part of this specification, illustrate embodiments consistent with this application and, together with the description, serve to explain the principles of this application. Detailed Implementation

[0063] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0064] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0065] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0066] like Figure 1 As shown, the front-to-back direction of the motorcycle is the length direction, the vertical direction of the motorcycle is the height direction, and the direction perpendicular to both the length and height directions is the width direction.

[0067] Compared to cars, motorcycles are a small and agile mode of transportation. For example... Figure 1 and Figure 2 As shown, the motorcycle 100 includes a frame 1, a body panel 2, a running gear 3, a suspension assembly, a power system 4, a power system 8, a control system, and a seat 6. At least a portion of the body panel 2 is mounted on the frame 1. The running gear 3 includes a front wheel 31 and a rear wheel 32. The suspension assembly includes a front suspension 51 and a rear suspension 52. The front wheel 31 is connected to the frame 1 via the front suspension 51, and the rear wheel 32 is connected to the frame 1 via the rear suspension 52. The power system 4 drives the running gear 3 and includes an engine 41, a fuel tank 42, and an air filter 43 mounted on the frame 1. The control system includes an ECU (Electronic Control Unit) 71. The power system 8 includes a battery and a rectifier / regulator 81 for voltage stabilization. The seat 6 is mounted on the body panel 2. Because the motorcycle 100 is relatively small and has many components, the arrangement of its structure is crucial.

[0068] Currently, motorcycles typically place the air filter below the fuel tank, the engine below the air filter, and the battery, ECU (also known as the vehicle computer), rectifier, and voltage regulator stacked under the seat. This arrangement suffers from problems such as structural congestion, low space utilization, and difficulty in heat dissipating the rectifier and voltage regulator. Furthermore, during motorcycle maintenance, it is necessary to connect the ECU wiring harness to the computer to obtain relevant parameters. The traditional setup requires removing the seat from the motorcycle first, followed by removing the components above the ECU before the connection can be made.

[0069] This application provides a motorcycle 100, such as Figure 1 , Figure 2 and Figure 2-a As shown, at least a portion of the fuel tank 42 of the motorcycle 100 is disposed on the frame 1 and located at the front of the frame 1, and at least a portion of the air filter 43 is disposed under the seat 6. A first receiving space 9 is formed between the fuel tank 42 and the air filter 43 along the length direction of the motorcycle 100, and at least a portion of the ECU 71 is disposed within the first receiving space 9.

[0070] Specifically, such as Figure 2-a As shown, at least a portion of the lower surface of the fuel tank 42, at least a portion of the upper surface of the air filter 43, and at least a portion of the frame 1 surround to form a first receiving space 9, and the remaining planes are further covered by body panels 2. This arrangement helps to enhance the installation stability of the ECU 71 structure and protect the ECU 71 from damage.

[0071] In one embodiment, the motorcycle 100 also includes an inclined plane 101 parallel to the lower surface of the fuel tank 42, and the upper surface of the air filter 43 is also configured to be parallel to the inclined plane 101, that is, the lower surface of the fuel tank 42 and the upper surface of the air filter 43 are configured to be parallel. Herein, parallel means approximately parallel.

[0072] Furthermore, such as Figure 2-a As shown, on a horizontal plane perpendicular to the height direction of the motorcycle 100, the inclined plane 101 intersects the horizontal plane at an angle α. The angle α can be set to be greater than 13° and less than 26°, or it can be set to be greater than 18° and less than 21°. In this application, based on the arrangement requirements of the relevant components, the angle α is set to 19°.

[0073] Furthermore, such as Figure 2-a As shown, the distance H between the lower surface of the fuel tank 42 and the upper surface of the air filter 43 can be set to a range greater than 57 mm and less than 72 mm, or greater than 62 mm and less than 67 mm. In this application, based on the actual size of the ECU, H is set to 65 mm.

[0074] In this embodiment, such as Figure 1 , Figure 2 and Figure 2-a As shown, by placing the ECU71 in the first accommodating space 9, the space between the fuel tank 42 and the air filter 43 is effectively utilized, while freeing up the space under the seat 6. This space can be used to place the larger air filter 43 or other structural components, thereby improving the space utilization of the motorcycle 100 and alleviating the problem of the motorcycle 100's structural congestion.

[0075] The function of the air filter 43 is to filter out dust, debris and moisture in the air to provide clean air to the engine 41 and prevent the engine 41 from being blocked or damaged by dust and debris. Therefore, the larger air filter 43 can provide the engine 41 with higher quality air, thereby improving the performance of the motorcycle 100 and giving the rider a better user experience.

[0076] Specifically, such as Figure 4 As shown, the motorcycle 100 also includes a first bracket 72, the ECU 71 is connected to the first bracket 72, and the first bracket 72 is connected to the frame 1.

[0077] like Figure 4As shown, the ECU71 is stably installed by fixing it to the first bracket 72 connected to the frame 1, so that the ECU71 will not collide with the fuel tank 42 or air filter 43 during the motorcycle 100's operation, thus protecting the ECU71 and other surrounding structures from damage.

[0078] More specifically, the motorcycle 100 also includes a first connector 73 and a second connector 74. The ECU 71 is connected to the first bracket 72 via the first connector 73, and the first bracket 72 is connected to the frame 1 via the second connector 74. The first connector 73 ensures a stable and reliable connection between the first bracket 72 and the ECU 71, and the second connector 74 ensures a stable and reliable connection between the first bracket 72 and the frame 1.

[0079] Preferably, the first connector 73 and the second connector 74 can be one, two or more. In this application, the number of the first connector 73 and the second connector 74 is set to multiple. The multiple first connectors 73 are arranged around the circumference of the ECU 71, and the multiple second connectors 74 are arranged around the width direction of the motorcycle 100.

[0080] Specifically, in this embodiment, four first connectors 73 are provided, which are arranged circumferentially at the four corners of the ECU 71, thereby making the connection between the ECU 71 and the first bracket 72 more reliable and preventing the ECU 71 from shaking relative to the first bracket 72. In this embodiment, at least two second connectors 74 are provided, which pass through the first bracket 72 along the width direction of the motorcycle 100 and are fixed to the frame 1, making the connection between the first bracket 72 and the frame 1 more reliable and preventing the first bracket 72 from shaking relative to the frame 1.

[0081] Specifically, the first connector 73 and the second connector 74 can be configured as bolts or other fasteners.

[0082] It is understood that the first bracket 72 can not only be detachably connected to the frame 1 via the first connector 73 and / or the second connector 74, but can also be configured as a non-detachable fastened connection to the frame 1 or be integrally formed. Furthermore, the first bracket 72 can also be connected to the air filter 43 and / or the fuel tank 42.

[0083] In one specific implementation, such as Figure 4 and Figure 5As shown, the first bracket 72 includes a mounting portion 721 and a fixing portion 722 for mounting the ECU 71. The mounting portion 721 and the fixing portion 722 are securely connected. Specifically, the mounting portion 721 and the fixing portion 722 are integrally formed. The second connector 74 passes through the fixing portion 722 and connects to the vehicle frame 1. The mounting portion 721 can fit against the lower surface of the ECU 71, so that the ECU 71 is securely mounted on the mounting portion 721, resulting in high installation reliability.

[0084] Furthermore, the control system also includes a first plug-in 76 and a first wiring harness 75. The first plug-in 76 is connected to the ECU 71, one end of the first wiring harness 75 is connected to the first plug-in 76, and the other end of the first wiring harness 75 is connected to the engine 41. Specifically, the first plug-in 76 is inserted into the side of the ECU 71. A certain angle is provided between the mounting part 721 and the fixing part 722, and a second receiving space 723 is formed within this angle. The first wiring harness 75 is at least partially disposed within the second receiving space 723. Specifically, the first wiring harness 75 passes through the second receiving space 723, which determines the direction of the first wiring harness 75 and protects the first wiring harness 75 from being squeezed or worn by other structures of the motorcycle 100. The insertion of the first plug-in 76 into the side of the ECU 71 facilitates the installation or removal of the first plug-in 76 from the left or right side of the motorcycle 100, allowing for parameter adjustment without disassembling the ECU 71.

[0085] Furthermore, such as Figure 3 As shown, the body panel 2 includes a body 21 and a first panel 22, which are detachably connected. In a projection plane perpendicular to the width direction of the motorcycle 100, along the width direction of the motorcycle 100, the projections of the first plug 76 and ECU 71 on this projection plane coincide with the projection of the first panel 22 on this projection plane.

[0086] In this embodiment, such as Figure 3 As shown, since the projections of the first plug-in 76 and ECU 71 on the projection plane perpendicular to the width direction of the motorcycle 100 coincide with the projection of the first cover 22 on the projection plane perpendicular to the width direction of the motorcycle 100, and the first cover 22 is detachably connected to the body 21, when the engineer needs to debug the motorcycle 100, he can directly remove the first cover 22 from the body 21 and disconnect the first plug-in 76 from the ECU 71 to connect to the external computer. There is no need to remove the seat 6, nor is there a need to remove the ECU 71 from the motorcycle 100. This simplifies the steps required to debug the motorcycle 100 and avoids multiple disassembly and reassembly of the motorcycle 100.

[0087] like Figure 6 and Figure 7As shown, the motorcycle 100 provided in this application has a body cover 2 with a ventilation section 231. The rectifier and voltage regulator 81 is installed on the side of the fuel tank 42 away from the seat 6. The rectifier and voltage regulator 81 is covered by the body cover 2. In a projection plane perpendicular to the length direction of the motorcycle 100, the projection of the ventilation section 231 on the projection plane coincides with the projection of the rectifier and voltage regulator 81 on the projection plane.

[0088] The rectifier voltage regulator 81 is an important component of the motorcycle 100. Its function is to rectify the alternating current generated by the electric motor into direct current, and then regulate the voltage to power the battery of the motorcycle 100 or other electrical appliances on the motorcycle 100. The rectifier voltage regulator 81 generates a lot of heat during operation. Therefore, the current arrangement of the rectifier voltage regulator 81 in the motorcycle 100 is not conducive to heat dissipation, which affects the operation of the rectifier voltage regulator 81 at higher temperatures.

[0089] In the solution provided in this application, the rectifier and voltage regulator 81 is connected to the fuel tank 42 and is located on the side of the fuel tank 42 away from the seat 6, at the front of the vehicle. The body cover 2 covers the outside of the fuel tank 42, and the rectifier and voltage regulator 81 is separated from the outside only by the body cover 2. A ventilation section 231 is provided on the body cover 2 at the position corresponding to the rectifier and voltage regulator 81. Along the length direction of the motorcycle 100, the projection of the ventilation section 231 on the projection plane perpendicular to the length direction of the motorcycle 100 coincides with the projection of the rectifier and voltage regulator 81 on the projection plane perpendicular to the length direction of the motorcycle 100. Thus, when the motorcycle 100 is in motion, cool air with a lower outside temperature can flow through the ventilation section 231 to the surface of the rectifier and voltage regulator 81 to cool it down and ensure the normal operation of the rectifier and voltage regulator 81. At the same time, the body cover 2 also protects the rectifier and voltage regulator 81 from damage caused by external impacts.

[0090] Specifically, such as Figure 6 As shown, the ventilation section 231 includes a plurality of ventilation holes 231a, which are arranged sequentially along the width direction of the motorcycle 100.

[0091] like Figure 6As shown, the ventilation section 231, configured with multiple ventilation holes 231a, slows down the airflow and reduces the impact of rapidly flowing air on the rectifier and voltage regulator 81. Simultaneously, the large total area of ​​the multiple ventilation holes 231a allows for greater air intake, resulting in better heat dissipation for the rectifier and voltage regulator 81. Compared to a single, integrated ventilation section 231, using multiple ventilation holes 231a avoids weakening the strength of the body panel 2. Since the body panel 2 is tilted relative to the vertical direction, the multiple ventilation holes 231a arranged sequentially along the width of the motorcycle 100 facilitate airflow to the rectifier and voltage regulator 81, improving its heat dissipation.

[0092] In one specific implementation, such as Figure 6 As shown, the rectifier voltage regulator 81 is provided with an air guide groove 811. Along the length direction of the motorcycle 100, the projection of the ventilation hole 231a on the projection surface of the rectifier voltage regulator 81 perpendicular to the length direction of the motorcycle 100 coincides with the projection of the air guide groove 811 on the projection surface.

[0093] In this embodiment, such as Figure 6 As shown, along the length of the motorcycle 100, at least a portion of the projection of the ventilation hole 231a onto the projection surface of the rectifier voltage regulator 81 perpendicular to the length of the motorcycle 100 coincides with the air guide groove 811, so that the external gas flowing to the surface of the rectifier voltage regulator 81 through the ventilation hole 231a flows on the air guide groove 811, thereby increasing the contact area between the external gas and the rectifier voltage regulator 81 and improving the heat dissipation effect.

[0094] As one implementation method, such as Figures 6-8 As shown, the power system 8 also includes a second bracket 82 and a third connector 84, and the rectifier voltage regulator 81 is mounted on the oil tank 42 via the second bracket 82 and the third connector 84.

[0095] In this implementation, one end of the second bracket 82 is fixedly connected to the oil tank 42, and the other end of the second bracket 82 is connected to the rectifier voltage regulator 81 through the third connector 84, thereby making the connection between the rectifier voltage regulator 81 and the oil tank 42 stable and reliable. It can be understood that the second bracket 82 and the rectifier voltage regulator 81 can also be connected by integral molding or welding.

[0096] like Figure 7 and Figure 8As shown, the third connector 84 can be one, two, or more. In this application, two third connectors 84 are provided, and the two third connectors 84 are arranged sequentially along the height direction of the motorcycle 100. Specifically, the two third connectors 84 can be respectively set at both ends of the rectifier voltage regulator 81, so that the rectifier voltage regulator 81 is more stably installed on the second bracket 82, reducing the possibility of the rectifier voltage regulator 81 falling off the second bracket 82.

[0097] Specifically, the third connector 84 can be configured as a bolt or other fastener to facilitate quick removal of the rectifier regulator 81 from the oil tank 42.

[0098] Furthermore, such as Figure 8 As shown, the power system 8 also includes a third bracket 83 for reducing vibration, which is disposed between the second bracket 82 and the rectifier voltage regulator 81.

[0099] The third bracket 83 can be made of softer plastic, thereby reducing the vibration of the rectifier voltage regulator 81 during the motorcycle 100's operation, making the rectifier voltage regulator 81 less prone to damage, and improving the reliability of the rectifier voltage regulator 81.

[0100] As another implementation, the rectifier voltage regulator 81 can also be mounted on the frame 1 and / or body panel 2 via the second bracket 82.

[0101] In one specific implementation, such as Figure 6 As shown, the power system 8 also includes a second plug-in 86 and a second wiring harness 85. The second plug-in 86 is connected to the rectifier voltage regulator 81. Specifically, the second plug-in 86 is plugged into the side of the rectifier voltage regulator 81. One end of the second wiring harness 85 is connected to the second plug-in 86, and the other end of the second wiring harness 85 is connected to the engine 41.

[0102] In this embodiment, the second plug-in 86 is inserted into the side of the rectifier voltage regulator 81. The second plug-in 86 does not block the air flowing to the rectifier voltage regulator 81 through the ventilation hole 231a, thus not affecting the heat dissipation of the rectifier voltage regulator 81. At the same time, since the engine 41 is located below the fuel tank 42, the length of the second wiring harness 85 connecting the second plug-in 86 and the engine 41 is relatively short, and the first wiring harness 75 and the second wiring harness 85 do not cross, making the overall vehicle wiring harness relatively simple.

[0103] In one specific implementation, such as Figure 6 As shown, the body panel 2 also includes a second panel 23 detachably connected to the main body 21, and a ventilation section 231 is disposed on the second panel 23. On a projection plane perpendicular to the length direction of the motorcycle 100, the projection of the second panel 23 on the projection plane coincides with the projection of the rectifier voltage regulator 81 on the projection plane.

[0104] In this embodiment, since the projection of the second cover 23 onto the projection plane perpendicular to the length of the motorcycle 100 coincides with the projection of the rectifier voltage regulator 81 onto the projection plane perpendicular to the length of the motorcycle 100, and the second cover 23 is detachably connected to the main body 21, when the rectifier voltage regulator 81 is damaged, only the second cover 23 needs to be removed to adjust or replace the rectifier voltage regulator 81, without disassembling the entire motorcycle 100, thus simplifying the steps for repairing the rectifier voltage regulator 81.

[0105] In addition to facilitating heat dissipation and disassembly / repair, placing the rectifier regulator 81 on the fuel tank 42 also helps to make full use of the vehicle's space. In a motorcycle with very limited assembly space, this makes full use of the limited space, resulting in a more compact and reasonable structure.

[0106] In one specific embodiment, the suspension assembly further includes a shock absorber connected to the frame 1 and disposed on the side of the frame 1 near the rectifier regulator 81.

[0107] Shock absorbers are used to mitigate and dampen vibrations and impacts caused by uneven road surfaces during motorcycle riding, ensuring smoothness and comfort, and improving the service life and handling stability of the motorcycle 100. Therefore, placing the shock absorber on the side of the frame 1 near the rectifier voltage regulator 81 can reduce the vibration and impact on the rectifier voltage regulator 81, thereby protecting it.

[0108] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
