Summary of the Invention

Problem to be Solved by the Invention

[0004] By the way, ECUs tend to increase in size due to functional integration, and when the ECU becomes larger, it tends to be difficult to arrange the ECU as in the technique described in Patent Document 1. That is, various vehicle body components are often arranged on the bottom plate, which causes restrictions in the width direction, making it difficult to arrange the ECU along the bottom plate. In addition, in general, the ECU needs to be arranged in a manner that prevents theft. The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a saddle-ride type vehicle in which the ECU can be easily arranged on a tray while ensuring anti-theft performance of the ECU even when the ECU is increased in size.

Means for Solving the Problem

[0005] A saddle-type vehicle comprises a tray having a bottom plate and vertical walls extending upward from at least one of the left or right ends of the bottom plate, vehicle body components housed in the tray, and an ECU that constitutes the control unit of the vehicle, wherein the ECU is arranged along the vertical wall such that its vertical length is longer than its width, and is sandwiched between a lid member attached to the tray and the vertical wall, and the vehicle body components are arranged on the side of the lid member opposite to the ECU. [Effects of the Invention]

[0006] Even if the ECU becomes larger, it is possible to provide a saddle-type vehicle that makes it easy to place the ECU on a tray while ensuring theft prevention of the ECU. [Brief explanation of the drawing]

[0038] Furthermore, an evaporative gas recovery pipe 29a extends in the front-rear direction from the top surface of the fuel tank 29, adjacent to the pump harness 212, to recover evaporated gas from within the fuel tank 29. The evaporative gas recovery pipe 29a is connected to a canister (not shown).

[0039] Figure 8 shows the relationship between the rear center cover 74, the ECU 200, and the ECU retaining lid 120. Figure 9 is a plan view of the rear center cover 74. In other words, Figure 9 is a diagram of Figure 8 with the ECU 200 and the ECU retaining lid 120 omitted. The rear center cover 74 has a bottom plate portion (bottom plate) 110, a front plate portion 111 extending upward from the front end of the bottom plate portion 110, and a pair of left and right side wall portions (vertical walls) 112, 113 provided at both the left and right ends of the bottom plate portion 110 and extending upward.

[0040] The bottom plate portion 110 is a plate-like shape that forms the largest surface area of ​​the rear center cover 74. The bottom plate portion 110 has thickness in the vertical direction. The bottom plate portion 110 extends upward towards the rear. The bottom plate portion 110 has a pair of left and right frame engagement portions 110a formed on it in accordance with the pair of left and right rear subframes 34. The frame engagement portions 110a extend along the seat frame 33. The frame engagement portions 110a are recessed upward so as to accommodate the upper surface of the rear subframe 34.

[0041] A center cover fixing portion 110b is formed at the rear end of the bottom plate portion 110. The center cover fixing portion 110b is formed between a pair of left and right frame engagement portions 110a. The front end of the rear fender 27 is fixed to the center cover fixing portion 110b. In front of the frame engagement portion 110a, a frustoconical box support portion 110c is formed that protrudes upward. The air cleaner box 102 is supported by the box support portion 110c. A square-shaped engagement hole 110d is formed on the right side of the box support portion 110c. A round-shaped pipe outlet portion 110e is formed on the left side of the box support portion 110c. The pipe portion 102c of the air cleaner box 102 is led downward from the pipe outlet portion 110e.

[0042] The front plate portion 111 has a tube outlet 111a that is cut out from top to bottom, corresponding to the front side of the pipe outlet portion 110e. The connecting tube 105 is led forward from the tube outlet 111a. An opening 111b is formed around the tube outlet 111a.

[0043] The side wall portions 112 and 113 have thickness in the left-right direction overall. The side wall portions 112 and 113 are formed in a stepped shape. The side wall portions 112 and 113 include lower side wall portions 112a and 113a extending upward from the bottom plate portion 110, stepped surface portions 112b and 113b extending outward in the vehicle width direction from the upper ends of the lower side wall portions 112a and 113a, upper side wall portions 112c and 113c extending upward from the outer ends of the stepped surface portions 112b and 113b in the vehicle width direction, and upper edge portions 112d and 113d projecting outward in the vehicle width direction from the upper ends of the upper side wall portions 112c and 113c.

[0044] On the right side wall portion 113, a substantially U-shaped connector cover portion 114 is formed at the front end of the stepped surface portion 113b. More specifically, the connector cover portion 114 has a pair of upper and lower legs 114a extending inward from the side wall portion 113 in the vehicle width direction, and a connecting portion 114b connecting the pair of upper and lower legs 114a.

[0045] A pair of engagement holes 113d1 and 113d2 are formed in the upper edge portion 113d. Covering portions 113e and 113f (see Figures 4, 7, 12, and 13), which have a roughly U-shaped cross-section, are formed around the engagement holes 113d1 and 113d2. The covering portions 113e and 113f extend downward from the upper edge portion 113d. Together with the upper part of the side wall 113c, the covering portions 113e and 113f form a cylindrical shape.

[0046] On the right side wall portion 113, an ECU (Electronic Control Unit) 200, which electronically controls each part of the saddle-type vehicle 10, is installed on the stepped surface portion 113b, the upper part of the side wall 113c, and the connector cover portion 114. The ECU 200 in this embodiment has a plate-like appearance with thickness. The ECU 200 comprises a roughly rectangular plate-shaped main body portion 201 (see Figure 4) that houses a circuit board and the like, and a connector portion 202 (see Figure 4) provided at the front end of the main body portion 201.

[0047] The main body portion 201 has different thicknesses (left-right widths) in the front-rear direction. That is, as shown in Figure 8, the main body portion 201 has a flush mounting surface 203, and the surface opposite to the mounting surface 203 has irregularities. The main body portion 201 has a front end (tip) 201a which has the maximum thickness, and a rear end (inner end) 201b which is thinner than the front end 201a. The connector portion 202 protrudes from the main body portion 201.

[0048] Figure 10 is a diagram of the ECU retaining lid 120. Figure 11 is a view of the ECU retaining lid 120 from a different angle than that shown in Figure 10. The ECU 200 is installed on the rear center cover 74, sandwiched between the ECU retaining lid (cover member) 120 and the side wall portion 113. The ECU retaining lid 120 has a main body portion 121 that extends in the vertical direction. The main body portion 121 has a shape that corresponds to the uneven shape of the ECU 200. The main body portion 121 has a rear portion 121a, an inclined portion 121b formed at the front end of the rear portion 121a that inclins inward in the vehicle width direction as it extends forward, and a front portion 121c formed at the front end of the inclined portion 121b that extends forward.

[0049] The main body portion 121 has a harness engagement portion 121d that protrudes inward in the vehicle width direction. The harness engagement portion 121d is composed of a pair of claw shapes. A downward extension portion 122 is formed at the lower end of the main body portion 121. The lower end of the downward extension portion 122 is bent inward in the vehicle width direction. A lower end engagement portion 122a, which is thinner than the downward extension portion 122, is formed at the tip of the downward extension portion 122.

[0050] An upper plate portion 123 is formed at the upper end of the main body portion 121, curving outward in the vehicle width direction. A pair of front and rear openings 123a are formed in the upper plate portion 123. A pair of front and rear upper engaging portions 124 are formed on the outer side of the front and rear openings 123a in the vehicle width direction, projecting downward. The pair of front and rear upper engaging portions 124 are equipped with claw portions 124a that project inward in the front and rear direction. The ECU retaining lid 120 has reinforcing ribs 125 that extend appropriately in the left-right and up-down directions.

[0051] Figure 12 is a view from below of the rear center cover 74 where the ECU200 is installed. Figure 13 is a cross-sectional view taken along line XIII-XIII in Figure 8. Next, we will explain one example of how to install the ECU200 on the rear center cover 74. As shown in Figures 7 and 8, in the rear center cover 74, the ECU 200 is positioned on the stepped surface portion 113b of the rear center cover 74 with its mounting surface 203 aligned with the right side wall portion 113. At this time, the connector portion 202 is inserted into the connector cover portion 114. In this state, the ECU 200 is held in place by the ECU holding lid 120. That is, the lower end engaging portion 122a of the ECU holding lid 120 is positioned along the vertical direction, and the lower end engaging portion 122a is inserted into the engaging hole 110d of the rear center cover 74 from above. Then, using the lower end engaging portion 122a as a pivot point, the ECU holding lid 120 is tilted to the right, causing the upper plate portion 123 to move to the right.

[0052] At this time, the upper plate portion 123 overlaps the upper edge portion 113d of the right side wall portion 113 from above. Therefore, by pushing the upper plate portion 123 downward, the upper engaging portion 124 is pushed into the engaging holes 113d1 and 113d2 of the upper edge portion 113d, and the claw portion 124a of the upper engaging portion 124 catches on the engaging holes 113d1 and 113d2. Thus, the ECU 200 is held covered by the ECU holding lid 120, and the ECU 200 is sandwiched between the upper part of the side wall 113c and the ECU holding lid 120, and the ECU 200 is installed on the rear center cover 74. At this time, the ECU 200 is positioned such that its height is greater than its width, in other words, it is positioned vertically. Therefore, it is easy to utilize the degree of freedom in the height direction, and it is expected that even if the ECU 200 is enlarged, it will be positioned while maintaining the layoutability on the rear center cover 74.

[0053] In this embodiment, the front connector portion 202 of the ECU 200 enters the connector cover portion 114. Also, the thick front end portion 201a of the ECU 200 interferes with the inclined portion 121b of the ECU retaining lid 120. Therefore, it is easier to prevent the ECU 200 from coming out in the front-rear direction. Furthermore, since the ECU retaining lid 120 overlaps with the seat frame 33 in a plan view of the vehicle body (see Figures 5 and 6), it is difficult to access the ECU retaining lid 120 from above.

[0054] Furthermore, as shown in Figures 4, 12, and 13, the upper engaging portion 124 has a claw shape in the front-rear direction that intersects the direction of oscillation with the lower engaging portion 122a as the pivot point, making it difficult to remove the ECU retaining lid 120 from the rear center cover 74 by oscillation operation alone. In addition, the claw portion 124a of the upper engaging portion 124 is hidden from the outside by the covering portions 113e and 113f. The presence of the covering portions 113e and 113f makes the claw portion 124a difficult to see and hinders external access, making it difficult to release the engagement of the claw portion 124a of the ECU retaining lid 120.

[0055] With the ECU 200 installed on the rear center cover 74, the fuel tank 29 and air cleaner box 102 are mounted on top of the rear center cover 74. That is, as shown in Figure 6, the harness 214 is clamped and engaged with the harness engagement portion 121d, making it possible to install the air cleaner box 102 while minimizing interference with the harness 214. At this time, the air cleaner box 102 is positioned to the side of the ECU retaining lid 120 (see Figure 7). Therefore, it is difficult to swing the ECU retaining lid 120, and difficult to remove the ECU retaining lid 120 and the ECU 200. Thus, theft prevention of the ECU 200 is ensured.

[0056] Furthermore, the air cleaner box 102 covers the ECU retaining lid 120 and the ECU 200 from above (see Figures 5 and 6). More specifically, the air cleaner box 102 is positioned so as to overlap with the lower end engaging portion 122a in a plan view. Therefore, the ECU 200 is less likely to be exposed externally by the air cleaner box 102, and is also less likely to be easily accessed from above. In addition, since the lower end engaging portion 122a is covered by the bottom surface of the air cleaner box 102, it is difficult to swing the ECU retaining lid 120, and therefore the theft prevention of the ECU 200 is increased.

[0057] As described above, according to this embodiment to which the present invention is applied, a saddle-type vehicle 10 comprises a rear center cover 74 having a bottom plate portion 110 and a side wall portion 113 extending upward from at least one of the left or right ends of the bottom plate portion 110, an air cleaner box 102 housed inside the rear center cover 74, and an ECU 200 which constitutes the control unit of the vehicle. The ECU 200 is arranged along the side wall portion 113 such that its vertical length is longer than its length in the vehicle width direction, and is sandwiched between the ECU retaining lid 120 attached to the rear center cover 74 and the side wall portion 113, with the air cleaner box 102 positioned on the side of the ECU retaining lid 120 opposite to the ECU 200. With this configuration, when the ECU 200 is placed on the rear center cover 74 having a side wall portion 113, by installing the ECU 200 along the side wall portion 113, it is possible to arrange the ECU 200 compactly in the width direction while utilizing the freedom in the height direction. Furthermore, since the ECU 200 is sandwiched between the ECU retaining lid 120 and the side wall portion 113, and the air cleaner box 102 is placed on the opposite side of the ECU retaining lid 120 from the ECU 200, it is possible to make it difficult to remove the ECU retaining lid 120 and enhance the theft prevention of the ECU 200. Therefore, with this configuration, even if the ECU 200 is enlarged, it is possible to provide a saddle-type vehicle 10 that makes it easy to place the ECU 200 on the rear center cover 74 while ensuring the theft prevention of the ECU 200.

[0058] In this embodiment, the rear center cover 74 is positioned below the seat 17, and the ECU retaining lid 120 is covered by the air cleaner box 102 in a plan view of the vehicle body. This configuration makes it difficult to access the ECU retaining lid 120 from above, thus making it easier to ensure theft prevention of the ECU 200.

[0059] Furthermore, in this embodiment, a seat frame 33 is provided to support the seat 17, and the ECU holding lid 120 is positioned below the seat frame 33 and overlaps with the seat frame 33 in a plan view of the vehicle body. This configuration makes it more difficult to access the ECU retaining lid 120 from above, thus making it easier to ensure the theft prevention of the ECU 200.

[0060] [Other embodiments] The embodiments described above represent only one aspect of the present invention and can be modified and applied as needed without departing from the spirit of the invention.

[0061] In the above embodiment, the configuration of the rear center cover 74 was described as an example of a tray, but the tray is not limited to the vehicle body cover 70. For example, the tray may be a tray member covered by the vehicle body cover 70. For example, it may be a tray member other than the vehicle body cover that is housed between the seat 17 and the rear fender 27.

[0062] In the above embodiment, a motorcycle having a front wheel 13 and a rear wheel 15 was used as an example to describe the saddle-type vehicle 10. However, the present invention is not limited thereto, and can be applied to three-wheeled saddle-type vehicles having two front or rear wheels, or saddle-type vehicles having four or more wheels.

[0063] [Configurations supported by the above embodiment] The above embodiment supports the following configuration.

[0064] (Configuration 1) A saddle-type vehicle comprising a tray having a bottom plate and vertical walls extending upward from at least one of the left or right ends of the bottom plate, a vehicle body component housed in the tray, and an ECU that constitutes the control unit of the vehicle, wherein the ECU is arranged along the vertical wall such that its vertical length is longer than its length in the vehicle width direction, and is sandwiched between a lid member attached to the tray and the vertical wall, and the vehicle body component is arranged on the side of the lid member opposite to the ECU. With this configuration, when arranging the ECU on a tray with vertical walls, the ECU can be positioned along the vertical walls, allowing for a compact arrangement in the width direction while utilizing the freedom in the height direction. Furthermore, since the ECU is sandwiched between the lid member and the vertical wall, and the vehicle body components are positioned on the side of the lid member opposite the ECU, the lid member is made difficult to remove, thereby enhancing theft prevention of the ECU. Therefore, with this configuration, even if the ECU is large, it is possible to provide a saddle-type vehicle that makes it easy to arrange the ECU on a tray while ensuring theft prevention of the ECU.

[0065] (Configuration 2) The saddle-type vehicle according to Configuration 1, characterized in that the tray is positioned below the seat, and the lid member is covered by the vehicle body component in a plan view of the vehicle body. This configuration makes it difficult to access the cover from above, thus making it easier to ensure theft prevention of the ECU.

[0066] (Configuration 3) A saddle-type vehicle according to Configuration 2, comprising a seat frame that supports the seat, wherein the lid member is positioned below the seat frame and overlaps with the seat frame in a plan view of the vehicle body. This configuration makes it more difficult to access the cover from above, thus making it easier to ensure theft prevention of the ECU. [Explanation of Symbols]
