[0003] International Publication No. 2020 / 012791
[0004] For example, when vehicle components are directly attached by providing bosses or the like on the battery case, if the battery case is to be diverted to another vehicle, redesign is required due to layout changes or the like. In addition, it is also necessary to arrange vehicle components that use voltages from low voltage to high voltage in suitable locations. Therefore, in an electric straddle-type vehicle that handles various voltages, it is desired to optimally arrange a plurality of components and realize a structure that can be easily mounted on a vehicle body.
[0005] In order to solve the above problem, an object of the present disclosure is to optimally arrange a plurality of components and realize a structure that can be easily mounted on a vehicle body.
[0006] As a means of solving the above problems, an aspect of the present disclosure has the following configuration: (1) An electric saddle-type vehicle (1) according to an aspect of the present disclosure includes a front frame (20) located at the front of the vehicle body and having a head pipe (2), a rear frame (30) located at the rear of the vehicle body and supporting a seat (3), a battery (4) located behind the head pipe (2) and in front of the seat (3), a motor (5) driven by the battery (4), a battery case (40) formed to accommodate the battery (4), and the battery case The battery case is equipped with a tray (100) positioned on top of a case (40) and supporting a plurality of components (70-72, 80, 90-93, 95, 96), wherein the plurality of components (70-72, 80, 90-93, 95, 96) include low-voltage components (70-72) positioned on one side of the tray (100) in the vehicle width direction, and high-voltage components (80) positioned on the other side of the tray (100) in the vehicle width direction and using a higher voltage than the low-voltage components (70-72). With this configuration, since the plurality of components are supported by the tray, there is no need to provide multiple bosses or the like on the battery case to attach the plurality of components. In addition, since the low-voltage components and high-voltage components are positioned spaced apart in the vehicle width direction, wiring harness routing and maintenance are easier compared to when the low-voltage components and high-voltage components are positioned on one side in the vehicle width direction.Therefore, it is possible to optimally arrange the plurality of components and realize a structure that can be easily mounted on the vehicle body.
[0007] (2) In the embodiment of (1) above, the tray (100) includes an upper surface portion (101) positioned on the upper surface of the battery case (40), and a left side portion (102) and a right side portion (103) positioned on the left and right sides of the battery case (40), wherein the low-voltage components (70-72) are positioned on one of the left side portion (102) and the right side portion (103), and the high-voltage components (80) are positioned on the other of the left side portion (102) and the right side portion (103). With this configuration, since the battery is positioned between the low-voltage components and the high-voltage components, the low-voltage components and the high-voltage components can be further spaced apart in the vehicle width direction compared to the case where the low-voltage components and the high-voltage components are positioned on the left and right sides of the upper surface portion.
[0008] (3) In the embodiment of (2) above, the plurality of components (70-72, 80, 90-93, 95, 96) may include an auxiliary battery (91) that is arranged on the upper surface (101) and operates the low-voltage components (70-72). With this configuration, the harness of the auxiliary battery can be extended from the upper surface in the direction of the vehicle width. Therefore, the harness of the auxiliary battery can be routed more easily compared to the case in which the auxiliary battery is arranged on either the left side or the right side.
[0009] (4) In the embodiment of (3) above, the plurality of parts (70-72, 80, 90-93, 95, 96) are arranged on the upper surface (101) and include vehicle parts (92, 93) that are different from the auxiliary battery (91), and the different vehicle parts (92, 93) may overlap with the auxiliary battery (91) when viewed from the front-rear direction of the vehicle body. With this configuration, the left side and right side can be separated in the vehicle width direction by vehicle parts different from the auxiliary battery. In addition, the width dimension of the electric saddle-type vehicle can be reduced compared to the case in which the vehicle parts different from the auxiliary battery do not overlap with the auxiliary battery when viewed from the front-rear direction of the vehicle body.
[0010] (5) In the embodiment of (4) above, the plurality of components (70-72, 80, 90-93, 95, 96) may include a low-voltage harness (95) positioned on one side of the tray (100) with the auxiliary battery (91) in between, and a high-voltage harness (96) positioned on the other side of the tray (100) with the auxiliary battery (91) in between, and using a higher voltage than the low-voltage harness (95). With this configuration, the harness can be routed in close proximity to electrical components positioned on one or the other of the left side and right side. In addition, the low-voltage harness and the high-voltage harness can be positioned spaced apart in the vehicle width direction.
[0011] (6) In any of the embodiments of (2) to (5) above, the vehicle body may further include a vehicle body cover (60) that covers the left side portion (102) and the right side portion (103) from the outside in the vehicle width direction, and at least one of the left side portion (102) and the right side portion (103) may be provided with a protruding portion (105) that protrudes in the vehicle width direction so as to be in contact with the vehicle body cover (60). With this configuration, the space formed between the vehicle body cover and the tray can be secured by the protruding portion.
[0012] (7) In the embodiment of (6) above, the plurality of components (70-72, 80, 90-93, 95, 96) may include an anti-theft device (72) positioned between the protrusion (105) and the battery case (40). With this configuration, the space formed between the protrusion and the battery case can be used to position the anti-theft device in a location that is difficult to access from the outside.
[0013] (8) In any of the embodiments of (2) to (7) above, the plurality of parts (70-72, 80, 90-93, 95, 96) include upper side parts (90-93) arranged on the upper surface portion (101), and the tray (100) includes a left half (100L) and a right half (100R) arranged on the left and right sides of the tray (100), and the left half (100L) and the right half (100R) may be connected via the upper side parts (90-93). With this configuration, it is possible to suppress an increase in the thickness of the tray compared to the case in which the left half and the right half are connected by overlapping them in the vertical direction of the vehicle body. This makes it possible to secure a larger storage space inside the vehicle body cover.
[0014] According to the electric saddle-type vehicle described herein, it is possible to optimally arrange multiple components and realize a structure that can be easily mounted on the vehicle body.

At least one of the left side portion 102 and the right side portion 103 is provided with a projection 105 (see Figure 11) that protrudes in the vehicle width direction so as to be able to contact the vehicle body cover 60.
[0038] In this embodiment, the protrusion 105 protrudes to the left from the left side surface 102 of the tray 100 toward the left side of the vehicle body cover 60 (the inner surface of the left cowl 60L). The protrusion 105 is positioned on the inside in the vehicle width direction of the rear center of the left side of the vehicle body cover 60 (the knee grip area where the driver's knees touch in a side view). The protrusion 105 protrudes so as to be close to or in contact with the inner surface of the left cowl 60L. The protrusion 105 may be connected to the left cowl 60L via an engaging member such as a clip.
[0039] The anti-theft device 72 is positioned between the protrusion 105 and the battery case 40. In this embodiment, the anti-theft device 72 is positioned between the tip of the protrusion 105 (outer end in the vehicle width direction) and the left side surface of the battery case 40. The anti-theft device 72 is positioned inward in the vehicle width direction from the left cowl 60L and the left side surface 102 of the tray 100. This makes effective use of space and prevents the anti-theft function from being deactivated from the outside.
[0040] Multiple components include upper surface components 90-93 (see Figure 9) arranged on the upper surface portion 101. Upper surface components 90-93 include, for example, an IMU 90 (Inertial Measurement Unit), an auxiliary battery 91, an inlet 92, a smart key unit 93, a band member (not shown), etc. The IMU 90 is an inertial measuring device that detects three-dimensional inertial motion (translational and rotational motion in three axes).

The anti-theft device mounting portion 123 is formed behind the ECU mounting portion 121 and above the BCU mounting portion 122. The anti-theft device mounting portion 123 is formed inward of the protruding portion 105 in the vehicle width direction. The anti-theft device mounting portion 123 is opened in the vertical direction so that the anti-theft device 72 can be attached to and detached from the protruding portion 105 from above. The anti-theft device mounting portion 123 has a rib or the like along the outer circumference of the anti-theft device 72.
[0052] The left side body portion 120 of the tray 100 is formed with an insertion hole 125 for passing a cooling water hose 97 (see Figure 7), a mounting hole 126 for attaching a clamp for securing the wiring of a fuse 73 or an ignition switch 74, and the like.
[0053] The right side portion 103 of the tray 100 (right half portion 100R) has a right side main body portion 130 that follows the right side of the battery case 40, a relay mounting portion 131 for mounting the relay 81, a communication device mounting portion 132 for mounting the communication device 82, and a PLC mounting portion 133 for mounting the PLC 80. The relay mounting portion 131, the communication device mounting portion 132, and the PLC mounting portion 133 are formed on the right side main body portion 130 at points spaced apart from each other.
[0054] The relay mounting portion 131 is formed on the upper part of the right side main body portion 130. The relay mounting portion 131 is formed in a shape that conforms to the outer shape of the relay 81 when viewed from the side. The relay mounting portion 131 has wall portions that conform to the front and bottom edges of the rectangular relay 81 which is long in the front-to-back direction when viewed from the side, and fixing portions to which fastening members such as bolts are fixed.
[0055] The communication device mounting portion 132 is formed on the front lower part of the right side main body portion 130. The communication device mounting portion 132 is formed in a concave shape that follows the outer shape of the communication device 82 when viewed from the side. The communication device mounting portion 132 has a wall portion that follows a rectangular shape (a rectangular shape that is long in the front-to-back direction) that is larger than the rectangular outer shape of the communication device 82 when viewed from the side, and a claw portion that can engage with the case of the communication device 82.
[0056] The PLC mounting portion 133 is formed on the lower rear side of the right side main body portion 130. The PLC mounting portion 133 is formed below the relay mounting portion 131 and behind the communication device mounting portion 132. The PLC mounting portion 133 is formed in a concave shape that conforms to the outer shape of the PLC 80 when viewed from the side. The PLC mounting portion 133 has ribs that conform to a polygonal shape larger than the rectangular outer shape of the PLC 80 when viewed from the side, and claw portions that can engage with the case of the PLC 80.
[0057] In this embodiment, ribs are formed around the PLC 80, protruding from the right side surface 103 of the right half 100R. Additionally, ribs are formed from the vehicle body cover 60 (right cowl 60R) toward the right side surface 103 of the right half 100R, surrounding the PLC 80. Each rib surrounding the PLC 80 has an interlocking structure (a structure in which positioning is performed by interlocking protrusions and indentations between parts at the joint). As a result, the PLC 80 is shielded from its surroundings.
[0058] The right side portion 103 of the tray 100 (right half portion 100R) has an insertion hole 135 for passing wiring through. The right side portion 103 also has mounting holes 136 for attaching clamps for fixing the wiring of the relay 81, communication device 82, or PLC 80.
[0059] In this embodiment, the left half 100L and the right half 100R are fixed to the battery case 40 via fastening members such as bolts. The left half 100L and the right half 100R are connected to each other at locations other than the fastening members by a flange for attaching the inlet 92 (part of the inlet mounting portion 111), a band member that supports the auxiliary battery 91 and the smart key unit 93, etc. The left half 100L and the right half 100R are not directly connected to each other. As a result, there is no need to connect the left half 100L and the right half 100R with overlapping joints or the like, and the thickness of the tray 100 does not increase. Therefore, it is possible to avoid compressing the storage space inside the vehicle body cover 60.
[0060] <Effects and Effects> As described above, the electric saddle-type vehicle 1 of the above embodiment comprises a front frame 20 located at the front of the vehicle body and having a head pipe 2, a rear frame 30 located at the rear of the vehicle body and supporting a seat 3, a battery 4 located behind the head pipe 2 and in front of the seat 3, a motor 5 driven by the battery 4, a battery case 40 formed to accommodate the battery 4, and a tray 100 located on top of the battery case 40 and supporting a plurality of components. The plurality of components include low-voltage components 70-72 located on one side of the tray 100 in the vehicle width direction, and a high-voltage component 80 located on the other side of the tray 100 in the vehicle width direction and using a higher voltage than the low-voltage components 70-72. With this configuration, since the plurality of components are supported by the tray 100, there is no need to provide a plurality of bosses or the like on the battery case 40 to attach the plurality of components. Furthermore, since the low-voltage components 70-72 and the high-voltage component 80 are spaced apart in the vehicle width direction, wiring harness routing and maintenance become easier compared to the case where the low-voltage components 70-72 and the high-voltage component 80 are arranged on one side in the vehicle width direction. Therefore, it is possible to achieve a structure in which multiple components are optimally arranged and can be easily mounted on the vehicle body.
[0061] In the above embodiment, the tray 100 includes an upper surface portion 101 positioned on the upper surface of the battery case 40, and a left side portion 102 and a right side portion 103 positioned on the left and right sides of the battery case 40. The low-voltage components 70-72 are positioned on one of the left side portion 102 and the right side portion 103. The high-voltage component 80 is positioned on the other of the left side portion 102 and the right side portion 103. With this configuration, since the battery 4 is positioned between the low-voltage components 70-72 and the high-voltage component 80, the low-voltage components 70-72 and the high-voltage component 80 can be further spaced apart in the vehicle width direction compared to the case where the low-voltage components 70-72 and the high-voltage component 80 are positioned on the left and right sides of the upper surface portion 101.
[0062] In the above embodiment, the multiple components are arranged on the upper surface 101 and include an auxiliary battery 91 that operates the low-voltage components 70-72. With this configuration, the harness of the auxiliary battery 91 can be extended from the upper surface 101 in the direction of the vehicle width. Therefore, the harness of the auxiliary battery 91 can be routed more easily compared to the case where the auxiliary battery 91 is arranged on either the left side surface 102 or the right side surface 103.
[0063] In the above embodiment, the multiple components are arranged on the upper surface 101 and include vehicle components 92 and 93 that are different from the auxiliary battery 91. The vehicle components 92 and 93 that are different from the auxiliary battery 91 overlap with the auxiliary battery 91 when viewed from the front-rear direction of the vehicle body. With this configuration, the vehicle components 92 and 93 that are different from the auxiliary battery 91 can separate the left side surface 102 and the right side surface 103 in the vehicle width direction. In addition, the width dimension of the electric saddle-type vehicle 1 can be reduced compared to the case where the vehicle components 92 and 93 that are different from the auxiliary battery 91 do not overlap with the auxiliary battery 91 when viewed from the front-rear direction of the vehicle body.
[0064] In the above embodiment, the plurality of components include a low-voltage harness 95 positioned on one side of the tray 100, flanking the auxiliary battery 91, and a high-voltage harness 96 positioned on the other side of the tray 100, flanking the auxiliary battery 91, and using a higher voltage than the low-voltage harness 95. With this configuration, the harness can be routed in close proximity to electrical components located on one or the other of the left side portion 102 and the right side portion 103. Furthermore, the low-voltage harness 95 and the high-voltage harness 96 can be positioned spaced apart in the vehicle width direction.
[0065] In the above embodiment, a vehicle body cover 60 is further provided that covers the left side portion 102 and the right side portion 103 from the outside in the vehicle width direction. At least one of the left side portion 102 and the right side portion 103 is provided with a protruding portion 105 that protrudes in the vehicle width direction so as to be able to contact the vehicle body cover 60. With this configuration, the space formed between the vehicle body cover 60 and the tray 100 can be secured by the protruding portion 105.
[0066] In the above embodiment, the plurality of components include an anti-theft device 72 positioned between the protrusion 105 and the battery case 40. With this configuration, the space formed between the protrusion 105 and the battery case 40 can be used to position the anti-theft device 72 in a location that is difficult to access from the outside.
[0067] In the above embodiment, the plurality of parts include upper side parts 90 to 93 arranged on the upper surface portion 101. The tray 100 includes a left half 100L and a right half 100R arranged on the left and right sides of the tray 100. The left half 100L and the right half 100R are connected via the upper side parts 90 to 93. With this configuration, it is possible to suppress an increase in the thickness of the tray 100 compared to when the left half 100L and the right half 100R are connected overlapping in the vertical direction of the vehicle body. This makes it possible to secure a larger storage space inside the vehicle body cover 60. For example, a coolant hose 97 (radiator hose, etc.) can be passed between the battery case 40 and the tray 100.
[0068] <Modification> In the above embodiment, the tray includes an upper surface portion positioned on the top surface of the battery case, and a left side portion and a right side portion positioned on the left and right sides of the battery case. The low-voltage components are positioned on one of the left and right side portions, and the high-voltage components are positioned on the other of the left and right side portions. However, the embodiment is not limited to this. For example, the low-voltage components and high-voltage components may be positioned on the left and right sides of the upper surface portion. The arrangement of the low-voltage components and high-voltage components can be changed according to the design specifications.
[0069] In the above embodiment, the multiple components were described as being arranged on the top surface and including an auxiliary battery that operates low-voltage components, but the invention is not limited to this. For example, the auxiliary battery may be located on either the left side or the right side. For example, the multiple components may not include an auxiliary battery. The arrangement of the auxiliary battery can be changed according to the design specifications.
[0070] In the above embodiment, the multiple components are arranged on the upper surface and include vehicle components different from the auxiliary battery, and the vehicle components different from the auxiliary battery are described as overlapping with the auxiliary battery when viewed from the front-rear direction of the vehicle body, but the embodiment is not limited to this. For example, the vehicle components different from the auxiliary battery do not have to overlap with the auxiliary battery when viewed from the front-rear direction of the vehicle body. The arrangement of the vehicle components different from the auxiliary battery can be changed according to the design specifications.
[0071] In the above embodiment, the multiple components were described with an example that included a low-voltage harness arranged on one side of the tray flanking the auxiliary battery, and a high-voltage harness arranged on the other side of the tray flanking the auxiliary battery and using a higher voltage than the low-voltage harness, but the embodiment is not limited to this. For example, the low-voltage harness and the high-voltage harness may be arranged on one of the two sides of the tray flanking the auxiliary battery. The arrangement of the low-voltage harness and the high-voltage harness can be changed according to the design specifications.
[0072] In the above embodiment, an example was described in which a vehicle body cover further covers the left and right sides from the outside in the vehicle width direction, and at least one of the left and right sides has a projection that protrudes in the vehicle width direction so as to be able to contact the vehicle body cover, but the invention is not limited to this. For example, the left and right sides do not have projections that protrude in the vehicle width direction so as to be able to contact the vehicle body cover. The manner in which the projections are installed can be changed according to the design specifications.
[0073] In the above embodiment, the multiple components were described with an example that included an anti-theft device placed between the protrusion and the battery case, but the invention is not limited to this. For example, the anti-theft device may be placed in a location other than between the protrusion and the battery case. The multiple components do not necessarily include an anti-theft device. The arrangement of the anti-theft device can be changed according to the design specifications.
[0074] In the above embodiment, the plurality of parts include an upper surface part positioned on the upper surface, and the tray includes a left half and a right half positioned on the left and right sides of the tray, with the left half and the right half connected via the upper surface part. However, the embodiment is not limited to this. For example, the left half and the right half may be connected by overlapping them in the vertical direction of the vehicle body. The manner in which the left half and the right half are connected can be changed according to the design specifications.
