[0063] For a better understanding of the technical solutions of the present application, the embodiments of the present application are described in detail below with reference to the drawings.

[0064] It should be clear that the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0065] The terminology used in the embodiments of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the present application. As used in the description of the embodiments of the present application and the appended claims, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

[0066] As shown in Figure 1 , the front-rear direction of the motorcycle is the length direction, the up-down direction of the motorcycle is the height direction, and the width direction is perpendicular to both the length direction and the height direction.

[0067] Compared with a car, the motorcycle 100 is a small and flexible vehicle. As shown in Figure 1 and Figure 2 , the motorcycle 100 includes a frame 1, a body covering 2, a walking assembly 3, a suspension assembly, a power system 4, a power supply system 8, a control system, a seat cushion 6 and the like. Among them, at least part of the body covering 2 is arranged on the frame 1, the walking assembly 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 through the front suspension 51, the rear wheel 32 is connected to the frame 1 through the rear suspension 52, the power system 4 is used to drive the walking assembly 3, the power system 4 includes an engine 41, an oil tank 42 and an air cleaner 43 arranged on the frame 1, the control system includes an ECU (Electronic Control Unit, Electronic Control Unit) 71, the power supply system 8 includes a battery and a rectifier voltage regulator 81 for stabilizing voltage, and the seat cushion 6 is arranged on the body covering 2. Since the motorcycle 100 is small and has many structures, how to arrange the structure of the motorcycle 100 is very important.

[0068] The existing motorcycle generally arranges the air cleaner below the oil tank, arranges the engine below the air cleaner, and arranges the battery, ECU (also known as vehicle computer, vehicle-mounted computer), rectifier voltage regulator and the like under the seat cushion. This arrangement has problems such as crowded structure, low space utilization, difficult heat dissipation of the rectifier voltage regulator, and the like. Further, in the maintenance process of the motorcycle, the wire harness of the ECU needs to be connected to the computer to further obtain relevant parameters. The traditional setting method makes it necessary to at least remove the seat cushion from the motorcycle first, and then further remove the components on the upper end of the ECU, before the connection operation can be performed.

[0069] The present application provides a motorcycle 100, as shown in Figure 1 , Figure 2 and Figure 2-aAs shown, at least part of the oil tank 42 of the motorcycle 100 is arranged on the frame 1 and located at the front side of the frame 1, at least part of the air cleaner 43 is arranged below the seat cushion 6, along the length direction of the motorcycle 100, the first accommodating space 9 is formed between the oil tank 42 and the air cleaner 43, and the ECU 71 is at least partially arranged in the first accommodating space 9.

[0070] Specifically, as shown in Figure 2-a , the lower surface of at least part of the oil tank 42, the upper surface of at least part of the air cleaner 43, and at least part of the frame 1 surround the first accommodating space 9, and the remaining planes are further covered by the body cover 2, which facilitates to enhance the installation stability of the ECU 71 structure and protect the ECU 71 from damage.

[0071] As an embodiment, the motorcycle 100 further comprises an inclined plane 101 parallel to the lower surface of the oil tank 42, and the upper surface of the air cleaner 43 is also arranged to be parallel to the inclined plane 101, that is, the lower surface of the oil tank 42 and the upper surface of the air cleaner 43 are arranged to be parallel. In this document, parallel means approximately parallel.

[0072] Further, as shown in Figure 2-a , in a horizontal plane perpendicular to the height direction of the motorcycle 100, the inclined plane 101 is inclinedly intersected with the horizontal plane and forms an included angle α, the angle α can be arranged to be greater than 13° and less than 26°, or can be arranged to be greater than 18° and less than 21°, in this application, based on the arrangement requirement of the related components, the angle α is arranged to be 19°.

[0073] Further, as shown in Figure 2-a , the distance H between the lower surface of the oil tank 42 and the upper surface of the air cleaner 43 can be arranged to be greater than 57mm and less than 72mm, or can be arranged to be greater than 62mm and less than 67mm, in this application, based on the actual size of the ECU, H is arranged to be 65mm.

[0074] In this embodiment, as shown in Figure 1 , Figure 2 and Figure 2-a , the ECU 71 is arranged in the first accommodating space 9, effectively utilizing the space between the oil tank 42 and the air cleaner 43, while leaving the space below the seat cushion 6, which can be used to place a larger volume of air cleaner 43 or other structural components, thereby improving the space utilization of the motorcycle 100 and alleviating the problem of crowded structure of the motorcycle 100.

[0075] The air filter 43 filters dust, sundries and moisture in the air to provide clean air for the engine 41, preventing the engine 41 from being blocked and damaged by dust and sundries. Therefore, the larger air filter 43 can provide higher quality air for the engine 41, thereby improving the performance of the motorcycle 100 and providing a better riding experience for the rider.

[0076] Specifically, as shown in Figure 4 The motorcycle 100 further comprises a first support 72, and the ECU 71 is connected to the first support 72, and the first support 72 is connected to the frame 1.

[0077] As shown in Figure 4 The ECU 71 is fixed on the first support 72 connected to the frame 1, which realizes stable installation of the ECU 71 and prevents the ECU 71 from colliding with the fuel tank 42 or the air filter 43 during the driving of the motorcycle 100, thereby protecting the ECU 71 and other structures around the ECU 71 from being damaged.

[0078] More specifically, the motorcycle 100 further comprises a first connecting member 73 and a second connecting member 74, and the ECU 71 is connected to the first support 72 through the first connecting member 73, and the first support 72 is connected to the frame 1 through the second connecting member 74. The first connecting member 73 makes the connection between the first support 72 and the ECU 71 stable and reliable, and the second connecting member 74 makes the connection between the first support 72 and the frame 1 stable and reliable.

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

[0080] Specifically, in this embodiment, four first connecting members 73 are provided, which are arranged at the four corners of the ECU 71 around the circumference, thereby making the connection between the ECU 71 and the first support 72 more reliable and preventing the ECU 71 from shaking relative to the first support 72. In this embodiment, the second connecting member 74 is provided as at least two, and the multiple second connecting members 74 are fixed to the frame 1 after penetrating through the first support 72 along the width direction of the motorcycle 100, thereby making the connection between the first support 72 and the frame 1 more reliable and preventing the first support 72 from shaking relative to the frame 1.

[0081] Specifically, the first connecting member 73 and the second connecting member 74 can be a bolt or other fastener.

[0082] It can be understood that the first support 72 can not only be detachably connected with the frame 1 through the first connecting member 73 and / or the second connecting member 74, but also be fixedly connected with the frame 1 or integrally formed with the frame 1. Further, the first support 72 can also be connected with the air cleaner 43 and / or the fuel tank 42.

[0083] In a specific embodiment, as shown in Figure 4 and Figure 5 , the first support 72 comprises a mounting portion 721 for mounting the ECU 71 and a fixing portion 722, and the mounting portion 721 and the fixing portion 722 are fixedly connected, specifically, integrally formed. The second connecting member 74 penetrates the fixing portion 722 and is connected with the frame 1. The mounting portion 721 can be attached to the lower surface of the ECU 71, so that the ECU 71 is stably mounted on the mounting portion 721, and the mounting reliability is high.

[0084] Further, the control system further comprises a first plug-in 76 connected with the ECU 71 and a first wire harness 75, one end of which is connected with the first plug-in 76 and the other end of which is connected with the engine 41. Specifically, the first plug-in 76 is plugged in the side surface of the ECU 71. The mounting portion 721 and the fixing portion 722 are arranged at a certain angle, and a second accommodating space 723 is formed in the angle, and the first wire harness 75 is at least partially arranged in the second accommodating space 723. Specifically, the first wire harness 75 passes through the second accommodating space 723 to determine the running direction of the first wire harness 75 and protect the first wire harness 75, so as to avoid damage of the first wire harness 75 caused by extrusion or abrasion of other structures of the motorcycle 100. The first plug-in 76 plugged in the side surface of the ECU 71 is beneficial to mounting or dismounting the first plug-in 76 on the left side or the right side of the motorcycle 100, and parameter debugging can be performed without dismounting the ECU 71.

[0085] Further, as shown in Figure 3 , the vehicle body cover 2 comprises a body 21 and first covers 22, and the first covers 22 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 projection of the first plug-in 76 and the ECU 71 on the projection plane coincides with the projection of the first cover 22 on the projection plane.

[0086] In the embodiment, as shown in Figure 3As shown, since the projection of the first plug-in 76 and the ECU 71 on the projection plane perpendicular to the width direction of the motorcycle 100 coincides 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 with the body 21, when the engineer needs to debug the motorcycle 100, the first cover 22 can be directly detached from the body 21, and then the first plug-in 76 is pulled out of the ECU 71 and connected with the external computer, without the need of detaching the seat cushion 6, and without the need of detaching the ECU 71 from the motorcycle 100, thus simplifying the steps required for debugging the motorcycle 100, and avoiding multiple disassembly and assembly of the motorcycle 100.

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

[0088] The rectifier voltage regulator 81 is an important component on the motorcycle 100, which functions to convert the alternating current generated by the motor into direct current, and then supply the direct current to the battery on the motorcycle 100 or to other electrical appliances on the motorcycle 100 after voltage stabilization. The rectifier voltage regulator 81 generates a lot of heat when working, and therefore the arrangement position of the rectifier voltage regulator 81 on the existing motorcycle 100 is not conducive to heat dissipation of the rectifier voltage regulator 81, which affects the working of the rectifier voltage regulator 81 at a higher temperature.

[0089] In the scheme provided by the application, the rectifier voltage regulator 81 is arranged to be connected with the fuel tank 42, and the rectifier voltage regulator 81 is arranged on the side of the fuel tank 42 away from the seat cushion 6 and at a position in front of the whole vehicle. The motorcycle 100 body cover 2 is arranged outside the fuel tank 42, and the rectifier voltage regulator 81 is separated from the outside only by the motorcycle 100 body cover 2. The ventilation part 231 is arranged on the motorcycle 100 body cover 2 at a position corresponding to the rectifier voltage regulator 81, and the projection of the ventilation part 231 on a projection plane perpendicular to the length direction of the motorcycle 100 coincides with the projection of the rectifier voltage regulator 81 on the projection plane perpendicular to the length direction of the motorcycle 100, so that when the motorcycle 100 is running, cold air with a lower temperature outside can flow to the surface of the rectifier voltage regulator 81 through the ventilation part 231 to cool the rectifier voltage regulator 81 and ensure the normal working of the rectifier voltage regulator 81. At the same time, the motorcycle 100 body cover 2 can also protect the rectifier voltage regulator 81 from being damaged by external impact.

[0090] Specifically, as shown in Figure 6As 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 6 As 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 connecting member 84 can be provided as one, two or more, in the present application, the third connecting member 84 is provided as two, the two third connecting members 84 are sequentially provided along the height direction of the motorcycle 100. Specifically, the two third connecting members 84 can be respectively provided at the two ends of the rectifier voltage regulator 81, so that the rectifier voltage regulator 81 is more stably mounted on the second support 82, and the possibility of the rectifier voltage regulator 81 falling off the second support 82 is reduced.

[0097] Specifically, the third connecting member 84 can be provided as a bolt or other fastener, so as to facilitate quick disassembly of the rectifier voltage regulator 81 from the fuel tank 42.

[0098] Further, as shown, Figure 8 The power supply system 8 further comprises a third support 83 for reducing vibration, the third support 83 is arranged between the second support 82 and the rectifier voltage regulator 81.

[0099] The third support 83 can be made of soft plastic, so as to reduce the vibration amount of the rectifier voltage regulator 81 during driving of the motorcycle 100, so that the rectifier voltage regulator 81 is not easy to be damaged, and the reliability of the rectifier voltage regulator 81 is improved.

[0100] As another embodiment, the rectifier voltage regulator 81 can also be arranged on the frame 1 and / or the body cover 2 through the second support 82.

[0101] In a specific embodiment, as shown, Figure 6 The power supply system 8 further comprises a second plug-in 86 and a second wire harness 85, the second plug-in 86 is connected with the rectifier voltage regulator 81, specifically, the second plug-in 86 is plugged on the side of the rectifier voltage regulator 81, one end of the second wire harness 85 is connected with the second plug-in 86, and the other end of the second wire harness 85 is connected with the engine 41.

[0102] In the present embodiment, the second plug-in 86 is plugged on the side of the rectifier voltage regulator 81, so that the second plug-in 86 does not block the air flowing to the rectifier voltage regulator 81 through the vent hole 231a, thereby 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 wire harness 85 connecting the second plug-in 86 and the engine 41 is short, and the first wire harness 75 and the second wire harness 85 do not cross, so that the wire harness of the whole vehicle is relatively simple.

[0103] In a specific embodiment, as shown, Figure 6 The body cover 2 further comprises a second cover 23 detachably connected with the body 21, and the ventilation portion 231 is arranged on the second cover 23. In a projection plane perpendicular to the length direction of the motorcycle 100, the projection of the second cover 23 on the projection plane coincides with the projection of the rectifier voltage regulator 81 on the projection plane.

[0104] In the embodiment, the projection of the second cover 23 on the projection plane perpendicular to the length direction of the motorcycle 100 coincides with the projection of the rectifier regulator 81 on the projection plane perpendicular to the length direction of the motorcycle 100, and the second cover 23 is detachably connected to the body 21. Therefore, when the rectifier regulator 81 is damaged, the rectifier regulator 81 can be debugged or replaced by only detaching the second cover 23, without disassembling the motorcycle 100, which simplifies the steps of maintaining the rectifier regulator 81.

[0105] In addition to facilitating heat dissipation and disassembly and maintenance, arranging the rectifier regulator 81 on the oil tank 42 also facilitates full use of the space of the motorcycle, and in a motorcycle with very limited assembly space, the limited space is fully utilized, so that the structure is more compact and reasonable.

[0106] In a specific embodiment, the suspension assembly further comprises a shock absorber, which is connected to the frame 1 and arranged on the side of the frame 1 close to the rectifier regulator 81.

[0107] The shock absorber is used to alleviate and attenuate the vibration and impact of the motorcycle 100 caused by the uneven road during driving, to ensure the smoothness and comfort of driving, and to improve the service life and the stability of the motorcycle 100. Therefore, arranging the shock absorber on the side of the frame 1 close to the rectifier regulator 81 can reduce the vibration and impact on the rectifier regulator 81, thereby protecting the rectifier regulator 81.

[0108] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application shall be included in the protection scope of the present application.
