Description

Technical Field

[0001] This subject matter generally relates to saddle-type two-wheeled vehicles. More specifically, but not exclusively, the present invention relates to storage structure components for saddle-type two-wheeled vehicles. Background Technology

[0002] Typically, two-wheeled vehicles provide a fuel storage structure assembly for storing fuel. This assembly is usually located at the rear or front of the vehicle. In scooter motorcycles, the storage component is located below the seat assembly and at the rear of the vehicle. However, in motorcycles, the fuel storage structure assembly is positioned along the main frame of the vehicle frame assembly. The fuel storage structure assembly is used to store the required capacity of fuel and facilitate a smooth and uninterrupted flow of fuel to the engine assembly when needed. In motorcycles, the fuel tank is made of a material comprising metal sheets, resin, or the like, and consists of an outer fuel tank body and an inner fuel tank body. In the case of a metal fuel tank, the outer and inner bodies are joined by a seam welding process. Attached Figure Description

[0016] Generally, in vehicles, storage structure components (such as fuel tank assemblies) are used to store the required capacity of fuel and facilitate a smooth and uninterrupted flow of fuel to the engine assembly when needed. Typically, the storage component is made of sheet metal and comprises an outer fuel tank body and an inner fuel tank body. The outer and inner fuel tank bodies are joined by seam welding. In two-wheeled vehicles such as motorcycles, the storage component is placed on the main tube of the vehicle frame assembly. In particular, the storage component is mounted to the frame at one or more locations. One type of mounting prevents movement of the storage component at its rear. Other mountings position the storage component on the main tube. Specifically, the inner fuel tank body of the storage component includes a "C"-shaped bracket configured to position the storage component onto the main frame. The inner fuel tank body curves around the main tube in a generally inverted "U"-shaped profile, forming a channel area below the fuel tank through which the main components of the frame typically pass in a front-to-rear direction. The curved fuel tank extends downward from the main frame of the vehicle frame assembly. Thus, two walls of the inner fuel tank body are positioned on either side of the main frame. Both walls are adjacent to the main frame via C-shaped brackets. Specifically, the C-shaped brackets are fixedly connected to the internal body of the fuel tank on one or more vertical sides of the U-shaped profile. The C-shaped brackets are typically attached to the internal body of the fuel tank via spot welding.

[0017] Typically, in saddle-type vehicles, the storage structure assembly is mounted on the vehicle's main frame ahead of the seat assembly. With increasing demand for additional features to reduce vehicle emissions, numerous systems need to be housed within and around the storage structure assembly, such as fuel injection systems that work in conjunction with the fuel pump unit, evaporative emission control devices, and fuel dispenser units.

[0018] The storage structure assembly, in particular, consists of three main parts: a right-side section, a left-side section, and an internal section. The right-side and left-side sections together form the external structure. The internal section is the internal structure. The internal structure is formed in a complex manner to accommodate space for support on the frame components.

[0019] The length and width of the vehicle are designed for easier maneuverability within a limited range. Therefore, the storage structure components are also designed to fit the maximum width of the vehicle. Such storage structure components should be constructed to support and / or accommodate all the systems described above.

[0020] Furthermore, the design of the storage structure assembly becomes highly complex if components such as the fuel pump unit and fuel dispenser unit are to be housed within the internal structure of the fuel tank. An evaporative emission control device also needs to be constructed within the space between the external and internal structures. In addition to accommodating the exterior of all the aforementioned components, the fuel tank should also be constructed as part of the receiving frame component. In particular, the evaporative emission control device is preferably placed between either the right or left side wall of the frame component and the internal structure of the storage structure assembly.

[0021] Typically, to achieve the above objectives, the storage structure assembly is shaped such that it is wider at the front and relatively narrower at the rear. The storage structure assembly contains an inverted U-shaped internal structure. This internal structure includes end plates with variable lateral clearance / width along the vehicle's longitudinal direction. This internal structure is designed to accommodate various components, such as the fuel pump unit, fuel dispenser unit, etc. Due to its shape and operating conditions, space is particularly limited for the fuel pump unit. To accommodate the fuel pump unit and other components inside / on the internal structure of the storage structure assembly, the shape of the internal structure becomes complex. The complex shape of the internal structure makes it difficult to accommodate on the frame components. Furthermore, encapsulating such a complex storage structure assembly within the width of the vehicle is also challenging.

[0022] Despite the aforementioned problems, the fuel pump unit needs to be placed within the available space of the internal structure to achieve a compact overall layout of the vehicle. However, such a location for the fuel pump unit may not be suitable for its efficient operation. For example, the fuel pump unit may not be able to pump out the minimum specified capacity of fuel. In this case, the fuel tank includes a dead zone where fuel is stored. This fuel stored in the dead zone cannot be used. Even if the fuel is usable within the storage structure assembly, the vehicle user must frequently refill the storage structure assembly. This is not an economical option for the vehicle user. Users may not want a storage structure assembly with a dead zone storing large amounts of fuel. Therefore, an improved vehicle layout design is needed that can overcome all the aforementioned problems and other known technical issues.

[0023] To address the problem described above regarding the construction of components such as fuel pump units, evaporative emission control devices, and fuel transmitter units due to space constraints between the internal structure of the storage structure components and the main frame of the frame components, the following aspects of the present invention are provided.

[0024] According to one embodiment of the invention, a two-wheeled motorcycle includes a frame assembly comprising a main frame extending obliquely rearward from the head tube. A storage structure assembly is supported on the main frame. The storage structure assembly is shaped to accommodate a portion of the main frame such that the storage structure assembly sits firmly and stably on the main frame, and the main frame passes through a channel formed in the storage structure. The storage structure assembly includes an internal structure and an external structure. The storage structure assembly is configured to support a fuel pump unit, an evaporative emission control device, and a fuel dispenser unit. All these components are communicatively connected to the storage structure assembly. The fuel pump unit and the fuel dispenser unit are attached to the inner surface of the internal structure. The fuel pump unit is disposed on the right side wall and the left side wall of the outer surface. The fuel dispenser unit is disposed on another wall remote from the wall containing the fuel pump unit.

[0025] The fuel dispenser unit includes a floating component. This floating component is positioned in a storage space between the internal and external structures. The floating component is designed to detect the fuel level within the internal structure. As a movable object, the floating component requires space to provide operational freedom. Therefore, the fuel pump unit and the fuel dispenser unit are positioned on opposite walls of the internal structure.

[0026] According to one embodiment of the invention, the storage structure assembly includes a wider front portion and a narrower rear portion. The storage structure assembly is configured to comfortably accommodate the rider's thighs when seated in a vehicle. The storage structure assembly includes an outer structure and an inner structure. The inner structure of the storage structure assembly is an inverted U-shaped structure. The inner structure includes a right side wall, a left side wall, and a central portion that joins either the right side wall or the left side wall of the outer structure. The outer structure includes an outer right side portion and an outer left side portion. These outer portions all externally protect the storage structure assembly.

[0027] According to an embodiment of the invention, the fuel pump unit is mounted on an inclined surface of the internal structure. The inclined surface has a substantially flat surface to provide stable mounting of the fuel pump unit. According to one embodiment, the inclined surface is oriented at a 45-degree angle relative to the ground surface. Moreover, the fuel pump unit is oriented towards the rear of the storage structure assembly. The storage structure assembly is configured to be wider at the front and relatively narrower at the rear. The fuel pump unit cannot be accommodated in the narrower portion of the storage structure assembly. The fuel pump is located and mounted in the wider portion of the storage structure assembly to provide operational freedom. In particular, the fuel pump unit is mounted on either the right or left side of the internal structure. Even though the fuel pump unit is mounted at the front of the storage structure assembly, the inclination of the fuel pump unit in the flat portion causes the fuel pump unit to tilt towards the narrower portion (i.e., the rear of the storage structure assembly).

[0028] Furthermore, the fuel pump unit is inclined towards the narrower rear portion of the storage structure assembly, located at the lowest point of the assembly. Therefore, the fuel pump unit is able to draw most of the fuel from the dead zone. This provides efficient fuel pumping from the lowest part of the storage structure assembly. Because of this, most of the fuel in the storage structure assembly is utilized. Therefore, even if there is a large amount of fuel in the storage structure assembly, the user does not need to frequently refill it. For example, even if there is fuel in the storage tank of the storage structure assembly, the user must refill it. Therefore, according to the present invention, the fuel capacity in the dead zone can be reduced. According to the present invention, the storage structure assembly provides the user with economical fuel use.

[0029] The orientation of the fuel pump unit toward the lowest part of the storage structure assembly allows the filter element to be oriented toward the narrower side (the rear side of the storage structure assembly when viewed from the side). This orientation of the filter element provides efficient fuel extraction from the lowest part of the dead zone capacity containing fuel from the storage structure assembly.

[0030] According to another embodiment of this application, the internal structure of the storage structure is configured as part of the receiving frame component. Specifically, the main frame of the frame assembly. Furthermore, the internal structure of the storage structure assembly is not symmetrical about the vehicle's mid-plane. The complex-shaped internal structure can still accommodate the required fuel capacity and is also housed within the main frame.

[0031] Furthermore, the evaporative emission control device is constructed in the space between the main frame and the internal structure. According to one embodiment, the evaporative emission control device is located on a sidewall opposite to the sidewall of the storage structure assembly, and includes a supply for filling fuel into the storage structure assembly. Moreover, the fuel pump unit and the evaporative emission control device cannot be positioned closer to each other within the storage structure assembly. This is due to the similar size of these components and insufficient space. Therefore, the fuel pump unit is positioned away from the evaporative emission control device. The fuel pump unit is positioned on a sidewall opposite to the sidewall supporting the evaporative emission control device, relative to the longitudinal mid-plane of the vehicle. Although the storage structure assembly has a complex shape, it has a smoother appearance due to its wider front and narrower rear, enabling it to accommodate the main frame, store the required capacity of fuel, and house both the fuel pump unit and the evaporative emission control device.

[0032] The right and left walls of the internal structure are divided by a longitudinal mid-plane running through them. All components supported by the internal structure of the storage structure assembly, namely the fuel dispenser unit and the fuel pump unit, are arranged along and adjacent to the longitudinal mid-plane of the vehicle. This configuration facilitates a smoother storage structure assembly and enables the storage of fuel while accommodating the cooperating components.

[0033] According to an embodiment of the invention, the evaporative emission control device is communicatively connected to the tipper valve. The tipper valve is configured to absorb fuel vapor from the fuel tank and return it to the storage structure assembly. The tipper valve is positioned away from either the first wall or the second wall including the fuel pump unit. The outer surface of the internal structure supporting the tipper valve is configured to have a flat portion to stably support the tipper valve.

[0034] According to one embodiment of the present invention, the fuel pump unit, the fuel dispenser unit, and the evaporative emission control device are disposed in a triangular portion on the outer surface. The triangular portion is formed by a virtual triangle.

[0035] According to one embodiment of the invention, the virtual triangle is formed by a first axis, a second axis, and a third axis. These axes intersect each other.

[0036] The fuel pump unit and fuel dispenser unit are along the first axis. The fuel dispenser unit and evaporative emission control device are along the second axis. The fuel pump unit and evaporative emission control device are along the third axis.

[0037] The first axis comprises a first length. The first length is a first length L1 that varies within the range of 90mm-165mm. The second axis comprises a second length L2 that varies within the range of 75mm-195mm. The third axis comprises a third length L3 that varies within the range of 90mm-160mm.

[0038] According to an embodiment of the present invention, the first axis and the second axis are oriented at a first angle varying within the range of 20 degrees to 80 degrees. The second axis and the third axis are oriented at a second angle varying within the range of 20 degrees to 80 degrees. The third axis and the first axis are oriented at a third angle varying within the range of 25 degrees to 130 degrees.

[0039] As described above, the mutual orientation of the aforementioned axes provides optimal space utilization within the storage structure assembly. Therefore, the storage structure assembly can accommodate and support all the aforementioned components, free up space within the main frame, and also store fuel within the internal structure. All of these functions are achieved, and the internal structure of the storage structure assembly features a complex shape and a smoother design without compromising its compact width and achieving a compact vehicle layout.

[0040] Furthermore, the arrangement of the fuel dispenser unit, fuel pump unit, and evaporative emission control device, as described above, ensures the efficient functioning of these components. Therefore, a large portion of the fuel within the internal structure is utilized. The location of the filter components allows even a minimum capacity of fuel to be filtered and used efficiently.

[0041] These and other advantages of this subject matter will be described in more detail below in conjunction with the accompanying drawings.

[0042] Figure 1 A right view of an exemplary saddle-type vehicle (e.g., a motorcycle) is shown. The motorcycle 100 includes a frame assembly 101 that includes a main frame 101a (schematically shown) extending obliquely rearward from a head tube 102, a front fork 103 mounted to the front of the frame assembly 101 and connected to a front wheel 104, an engine assembly 105 supported by the frame assembly 101, and a rear wheel 106 supported by the rear of the frame assembly 101.

[0043] In the motorcycle shown, the head tube 102 rotatably supports a steering shaft (not shown) within a certain range. The front fork 103 is pivotally supported by the head tube 102. At the upper part of the head tube 102, the handlebar assembly 107 is rotatably and integrally connected to the steering shaft (not shown). The front wheel 104 is journaled to the lower end of the front fork 103, and the front wheel 104 rotates within a certain range by steering the handlebar assembly 107.

[0044] The front fender 108 is mounted on the front fork 103 to cover the upper part of the front wheel 104. The rear wheel 106 is journal-connected to the rear end of the main frame 101.

[0045] At the front of the frame assembly 101, the storage structure assembly 109 is positioned directly behind the handlebar assembly 107. The seat assembly 110 is positioned behind the storage structure assembly 109. The seat assembly 110 includes a front seat 110a and a rear seat 110b. The front seat 110a is positioned directly behind the storage structure assembly 109, while the rear seat 110b is positioned rearward relative to the front seat 110a.

[0046] The engine assembly 105 is supported to the frame assembly 101 by being suspended in the lower front portion of the frame assembly 101. The engine assembly 105 is equipped with an exhaust system 112 and includes an exhaust pipe connected to the engine assembly and a muffler connected to the exhaust pipe. The muffler extends rearward along the right side of the rear wheel 106.

[0047] Furthermore, a swing arm 113 is pivotally connected to the lower rear portion of the frame assembly 101, and the swing arm 113 extends rearward. The rear wheel 106 is rotatably supported at the rear end of the swing arm 113. At least one shock absorber 114 is supported at one end by the swing arm 113. Power from the engine assembly 105, suspended at the lower front portion of the main frame 101, is transmitted to the rear wheel 106 via a power transmission mechanism such as a drive chain (not shown) to drive and rotate the rear wheel 106.

[0048] The storage structure assembly is covered by an outer casing. In another embodiment, a portion of the side casing of the storage structure assembly extends to engage with the side casings or panels on either side of the saddle-type vehicle to eliminate any parting lines or gaps between the two panels. This reduces the number of main panels while preventing component warping to avoid having very large main panels.

[0049] Figure 2 This diagram shows a bottom view of a storage structure assembly assembled onto a frame assembly. The storage structure assembly 109 comprises an outer structure 109a and an inner structure 109b. The outer structure 109a protects the storage structure assembly 109 from external impacts. The inner structure 109b is located below the outer structure 109a and is protected by the outer structure 109a. The inner structure is configured to be housed on the main frame 101a of the frame assembly 101. The storage structure assembly 109 is supported on the main frame 101a along the longitudinal midplane XY of the vehicle.

[0050] According to one embodiment of the invention, the storage structure assembly 109 is configured such that it includes a front portion that is wider than a narrower rear portion. The wider front portion BR and the narrower NR are designed to ergonomically support the rider's thighs when seated in the vehicle. Furthermore, this type of configuration provides a smoother storage structure assembly 109. Such a storage structure assembly can be easily accommodated in a vehicle and provides easier operation within the vehicle's limited width.

[0051] According to one embodiment of the invention, the internal structure 109b is configured such that a predetermined space, namely a first distance d1, exists between the right side wall 109bx of the internal structure 109b and the main frame 101a, and a predetermined space, namely a second distance d2, exists between the left side wall 109by of the internal structure 109b and the main frame 101a. These first distances d1 and second distances d2 are formed relative to the main frame 101a in the internal structure 109b to accommodate various components configured to work in conjunction with the storage structure assembly 109. Although the shape of the internal structure 109b has become complex and has an inverted "U"-shaped profile to form a channel, it is able to provide space to accommodate various components surrounding the main frame 101a, providing space for the main frame and also having a smoother width, providing rider comfort while improving vehicle maneuverability. A detailed description of the various components accommodated is described in the following paragraphs.

[0052] Figure 3An exploded perspective view of the storage structure assembly is shown. The storage structure assembly 109 includes an external structure 109a, an internal structure 109b, and various components functionally connected to and partially housed within a channel formed by the internal structure 109b of the storage structure assembly 109. The various components include a fuel pump unit 201, which includes a filter component 201a, a fuel dispenser unit 203, which includes one or more floating components 203a, and an evaporative emission control device 202, which is communicatively connected to a tilting valve 202a.

[0053] A filter element 201a is disposed in the space between the inner structure 109b and the outer structure 109a. In this embodiment, the fuel pump unit 201 is oriented such that the filter element 201a is tilted (not shown) towards the lowest portion DS (not shown) of the storage structure assembly 109, allowing the filter element 201a to contact fuel present in the lowest portion of the storage structure. One or more floating elements 203a are disposed between the inner structure 109b and the outer structure 109a, while the fuel dispenser unit 203 is mounted on the inner surface 204 of the inner structure 109b. A reversing valve 202a and an evaporative emission control device 202 are communicatively connected to each other and also communicatively connected to the storage structure assembly 109. Both the reversing valve 202a and the evaporative emission control device 202 are mounted on the inner surface 204 of the inner structure 109b.

[0054] Figure 4a The left view shows the internal structure of the storage structure component. Figure 4b Show along as Figure 4a The diagram shows a cross-sectional view of the internal structure taken along the BB axis. The internal structure includes a right side wall 109bx and a left side wall 109by. The right side wall 109bx and the left side wall 109by bridge together from the top to form a channel between them. After the channel, the internal structure tapers gradually downwards towards the rear and has a generally flat horizontal portion (109bz) configured to couple the storage structure assembly to the vehicle at the rear region of the storage structure assembly. The right side wall 109bx and the left side wall 109by are divided by a longitudinal median plane XY that runs through them. The left rear portion of the internal structure 109b extends away from the longitudinal median plane XY, increasing the lateral distance d2. The left rear portion includes an inclined surface 205. The inclined surface 205 is oriented at a predetermined angle α relative to the ground plane GP. For example, the inclined surface 205 is oriented at an angle of approximately 45 degrees relative to the ground plane GP.

[0055] According to one embodiment of the invention, a fuel pump unit 201 is mounted on an inclined surface 205 of an internal structure 109b. The inclined surface 205 has a substantially flat portion that is substantially orthogonal to the mounting axis KK' of the fuel pump unit 201. This arrangement provides a stable support and mounting for the fuel pump unit 201. Furthermore, the fuel pump unit 202 is oriented such that its axis KK' is oriented towards the rear of a storage structure assembly 109 (not shown). The storage structure assembly 109 is configured to be wider at the front and relatively narrower at the rear. The fuel pump unit 201 cannot be accommodated in the narrower portion of the storage structure assembly 109; therefore, the inclined surface 205 has been configured to achieve a compact package of the fuel pump unit 201. The fuel pump unit 201 is located and mounted in the wider portion of the storage structure assembly 109 to provide operational freedom. In particular, the fuel pump unit 201 is mounted to either the right side wall 109bx or the left side wall 109by of the internal structure 109b. Although the fuel pump unit 201 is mounted on the front of the storage structure assembly 109 (not shown), the inclination of the fuel pump unit 201 on the flat portion causes the fuel pump unit 201 to tilt toward the narrower portion, which is the rear and lowest portion of the storage structure assembly 109, thereby allowing the filter member to functionally enter the lowest storage space in the storage structure.

[0056] Furthermore, the fuel pump unit 201, inclined towards the narrower rear portion of the storage structure assembly 109, is located at the lowest part of the storage structure assembly 109. Therefore, the fuel pump unit 201 is able to draw most of the fuel from the lowest portion. This provides efficient pumping of fuel from the lowest portion of the storage structure assembly 109. Because of this, most of the fuel in the storage structure assembly 109 is utilized. Therefore, even when a large amount of fuel exists in the storage structure assembly 109, the user does not need to repeatedly refill the storage structure assembly 109. Thus, according to the invention, a smaller fuel capacity in the dead zone can be achieved. According to one embodiment, the fuel transmitter 203 is mounted on the rear conical wall or inclined surface 205 of the internal structure 109b, with its mounting axis KK' pointing rearward and downward, intersecting the mounting axis LL' of the fuel transmitter unit 203 at an acute angle therebetween, thereby allowing for efficient pumping of fuel from the lowest portion of the storage structure assembly 109. Figure 4a When viewed in the side view of the vehicles, they are constructed in essentially opposite directions.

[0057] Figure 5a A bottom view showing the internal structure of a storage structure component according to a second embodiment of the present invention. Figure 5b Show along as Figure 5aThe diagram shows a cross-sectional view of the internal structure taken along axis AA. Fuel dispenser unit 203 is attached to inner surface 204. Fuel dispenser unit 203 includes a floating member 203a. The floating member 203a is disposed in a storage space (not shown) between internal structure 109b and external structure 109a (not shown). The floating member 203a is configured to detect the fuel level in the storage space. The floating member 203a is a pivoting object and requires space to provide the degree of freedom for pivoting operation. In this embodiment, fuel pump unit 201 is disposed on the rear conical wall or inclined surface 205 of internal structure 109b, its mounting axis KK' pointing substantially forward and downward towards the storage structure, and fuel dispenser unit 203 is mounted on a substantially horizontal portion 109bz, its mounting axis LL' pointing substantially downward and intersecting the axis KK' of fuel pump 201 at an acute angle therebetween, thus they are configured in substantially opposite directions when viewed in a side view of the vehicle. Therefore, the fuel pump unit 201 and the fuel transmitter unit 203 are disposed on opposite walls of the internal structure 109b.

[0058] In this embodiment, the fuel pump unit 201 is disposed on the left side wall 109by of the internal structure 109b. The filter member 201a is disposed facing the inner surface 204 of the internal structure 109b. The floating member 203a is disposed opposite to the fuel pump unit 201, and the fuel dispenser unit 203 is disposed away from the left side wall 109by.

[0059] Figure 6 A bottom view of a storage structure assembly including various components positioned according to a first embodiment is shown. According to a first embodiment of this application, the fuel pump unit 201, fuel dispenser unit 203, and evaporative emission control device 202 are arranged in a triangular layout on the inner surface 204 of the internal structure 109b. The triangular layout is formed by a virtual triangle REX.

[0060] According to a first embodiment of this application, the virtual triangle REX is formed by a first axis RE, a second axis EX, and a third axis XR. These axes RE, EX, and XR intersect each other.

[0061] Fuel pump unit 201 and fuel dispenser unit 203 are arranged along the first axis RE. Fuel dispenser unit 203 and evaporative emission control device 202 are arranged along the second axis EX. Fuel pump unit 201 and evaporative emission control device 202 are arranged along the third axis XR.

[0062] As described above, the orientation of the aforementioned axes relative to each other provides optimal space utilization within the storage structure assembly 109. Therefore, the storage structure assembly 109 is able to accommodate and support all the aforementioned components, free up space for a portion of the main frame (not shown), and also store fuel within the internal structure 109b. All of these functions are achieved in conjunction with the complex shape of the storage structure assembly 109 and a smoother design of its internal structure.

[0063] Furthermore, the arrangement of the fuel dispenser unit 203, fuel pump unit 201, and evaporative emission control device 202, as described above, ensures the efficient functioning of these components. Therefore, a large portion of the fuel within the internal structure is utilized. The location of the filter component (not shown) allows even a minimum capacity of fuel to be filtered.

[0064] In this embodiment, the evaporative emission control device is positioned so that its main axis is horizontally aligned with the vehicle's longitudinal mid-plane XY. Furthermore, according to this embodiment, the tilt valve 202a is positioned outside the virtual triangle REX, close to the evaporative emission control device 202. Therefore, in this embodiment, the tilt valve 202a can be connected to the evaporative emission control device 202 via a relatively short hose. The hose can also be connected between them without any sharp bends, which is also preferred for smooth fuel vapor flow. With a shorter hose length, fuel vapor can easily pass through the hose, and less space is left for reverse travel of fuel vapor if no reverse flow is desired.

[0065] Figure 7 A bottom view of a storage structure assembly according to a second embodiment of this application is shown. According to the second embodiment, an evaporative emission control device 202 is mounted on the right side wall 109bx of the internal structure 109b, while a fuel pump unit 201 is disposed away from the evaporative emission control device 202. In particular, the fuel pump unit 201 is disposed on an inclined surface 205 disposed away from the right side wall 109bx.

[0066] According to a first embodiment of this application, the fuel pump unit 201, the fuel transmitter unit 203, and the evaporative emission control device 202 are arranged in a triangular layout on the inner surface 204 of the internal structure 109b. This triangular layout is formed by a virtual triangle REX.

[0067] According to a first embodiment of this application, the virtual triangle REX is formed by a first axis RE, a second axis EX, and a third axis XR. These axes RE, EX, and XR intersect each other.

[0068] Fuel pump unit 201 and fuel dispenser unit 203 are arranged along the first axis RE. Fuel dispenser unit 203 and evaporative emission control device 202 are arranged along the second axis EX. Fuel pump unit 201 and evaporative emission control device 202 are arranged along the third axis XR.

[0069] In this embodiment, the evaporative emission control device is positioned horizontally along the longitudinal mid-plane XY of the vehicle, with its main axis aligned with the mid-plane. Furthermore, according to this embodiment, the tilt valve 202a is located outside the virtual triangle REX and away from the evaporative emission control device 202. Therefore, in this embodiment, the tilt valve 202a is located on either the right or left side wall opposite the evaporative emission control device 202. In this embodiment, the tilt valve 202a is located at approximately the same mounting height as the evaporative emission control device 202. Therefore, the travel of fuel vapor is easier, and reverse travel of fuel vapor is prevented to a greater extent.

[0070] The first axis RE comprises a first length. The first length is a first length L1 that varies within the range of 90mm-165mm. The second axis EX comprises a second length L2 that varies within the range of 75mm-195mm. The third axis XR comprises a third length L3 that varies within the range of 90mm-160mm.

[0071] According to an embodiment of the present invention, the first axis RE and the second axis EX are oriented at a first angle θ1 that varies within the range of 20 degrees to 80 degrees. The second axis and the third axis are oriented at a second angle θ2 that varies within the range of 20 degrees to 80 degrees. The third axis and the first axis are oriented at a third angle θ3 that varies within the range of 25 degrees to 130 degrees.

[0072] Figure 8a A bottom-view perspective view of the storage structure components is shown. Figure 8b It shows Figure 8a A detailed view of the section indicated in the image. Figure 8b A mounting member 206 for a fuel pump unit (not shown) on an internal structure 109b is illustrated. In this embodiment, the mounting member 206 includes a protrusion 201b extending inward from its inner periphery (not shown) toward the fuel pump unit 201 (not shown). The protrusion 201b is provided to facilitate the installation of the fuel pump unit 201 (not shown) during assembly onto the internal structure 109b. The protrusion 201b ensures that the fuel pump unit 201 is assembled only in the required direction and does not allow the fuel pump unit 201 to be incorrectly positioned on the mounting member 206. The protrusion 201b serves as an indicator of the correct placement of the fuel pump unit 201, thus optimizing the assembly time involved in assembling the fuel pump unit 201.

[0073] Furthermore, due to the protrusion 201b, the fuel pump unit 201 will not be misaligned or installed in any other position. Therefore, the desired high-efficiency function of the fuel pump unit 201 is achieved.

[0074] According to one embodiment of the invention, mounting member 206 is configured to function as a sealing member to provide proper mounting of fuel pump unit 201 to internal structure 109b.

[0075] Figure 8c As shown in Figure 8b A detailed view of the mounting member is shown. In this embodiment, the mounting member 206 is provided with at least two protrusions 201b on its inner periphery 207. Therefore, a portion (not shown) on the fuel pump unit includes at least two receiving portions configured to receive at least two protrusions 201b. This configuration fixes the orientation of the mounting member during assembly and ensures error-proof assembly.
