Summary of the Invention

Problems to be Solved by the Invention

[0004] An object of the present disclosure is to provide an off-road vehicle capable of suppressing an increase in the temperature of the passenger space.

Means for Solving the Problems

[0005] The present disclosure is a passenger space where passengers are located, a front space for accommodating in-vehicle components in front of the passenger space, a partition wall partitioning the passenger space and the front space, a radiator disposed in the front space, a fan in the front space that draws in air in front of the radiator and discharges it rearward, In the aforementioned front space, an air guide is positioned behind the fan and at a distance in front of the partition wall, and guides the fan exhaust air that has passed through the radiator by the fan in a direction away from the partition wall in the vehicle width direction outwards. To provide a vehicle that can travel on rough terrain.

[0006] In the off-road vehicle described herein, the fan exhaust air is guided by an air guide in a direction away from the partition wall in the vehicle width direction. As a result, collision of the fan exhaust air with the partition wall can be suppressed. This suppresses the temperature rise in the passenger compartment caused by the temperature rise of the partition wall. [Brief explanation of the drawing]

[Figure 7] This is a cross-sectional view of the air guide along section VII-VII in Figure 5. [Figure 8] This is a side view of the off-road vehicle according to this embodiment. [Modes for carrying out the invention]

[0008] The embodiments of this disclosure will be described below with reference to the attached drawings.

[0009] Off-road vehicles are primarily designed for driving on unpaved mountain roads, forest roads, muddy areas, rocky terrain, and other off-road surfaces, including grasslands, gravel, and sandy areas. Hereafter, off-road vehicle 1 will simply be referred to as vehicle 1.

[0010] In this specification, "front," "rear," "left," and "right" refer to the forward, rear, left, and right directions as viewed from the perspective of an occupant in Vehicle 1. The vertical direction is defined as the height direction of Vehicle 1. The left-right direction corresponds to the width direction of Vehicle 1.

[0011] The cross-sectional view of vehicle 1 shown in Figure 1 is a view of vehicle 1 from above, obtained by cutting vehicle 1 with a plane perpendicular to the vertical direction. The height of this cross-section coincides with the height of the air collection section 95 of the air guide 9 (see Figure 5), which will be described later. Note that some components of vehicle 1 (headlights, hood, etc.) are omitted in the following drawings.

[0012] Vehicle 1 is defined as having a passenger compartment V1 for the occupants and a front compartment V2 located in front of the passenger compartment V1 for housing on-board components. The passenger compartment V1 is enclosed by a rops. Rops is an abbreviation for rollover protection structure and is part of the vehicle frame 17, which will be described later. The passenger compartment V1 includes the space where the driver sits. The passenger compartment V1 is provided with a driver's seat and a steering wheel, etc., located in front of the driver's seat (not shown).

[0013] Vehicle 1 has a partition wall 2 that separates the passenger space V1 from the front space V2. The front space V2 is the space in front of the partition wall 2 within vehicle 1. As shown in Figure 1, the partition wall 2 extends in the vehicle width direction and is connected to two side walls 16 that define the vehicle width end of the passenger space V1.

[0014] Vehicle 1 has front wheels 4 arranged on the left and right respectively, arms 15 connected to the respective front wheels 4, and a suspension 5 connected to the arms 15. The front wheels 4, the suspension 5, and the arms 15 are arranged within the front space V2. The suspension 5 is a component that absorbs vibrations of the vehicle 1. In the present embodiment, the suspension 5 extends inclined outward in the vehicle width direction from the upper end downward when viewed from the front. The suspension 5 is stretchable along the extension direction. The inclination angle of the suspension 5 when it extends is smaller than the inclination angle when the suspension 5 retracts.

[0015] Vehicle 1 has in the front space V2 a front grille 18, a radiator 6 arranged behind the front grille 18, a fan 7 arranged behind the radiator 6, and a fan cover 8 covering the fan 7. The fan 7 contacts the surrounding air by rotating the blades 7a of the fan 7 around the rotation axis, and moves the air in the front to the rear. The fan cover 8 covers the blades 7a of the fan 7 and has a circular shape when viewed from the front. The front grille 18 is exposed on the outside of the vehicle 1. The front grille 18 protects the radiator 6 so that pebbles or the like do not collide with the radiator 6 arranged behind.

[0016] In the present embodiment, the radiator 6 is a heat exchanger for cooling the engine that is the drive source of the vehicle 1. The shape of the radiator 6 is rectangular when viewed from the front. The radiator 6 is connected to a cooling water pipe 10a for cooling the engine. The cooling water for cooling the engine circulates within the radiator 6 and the cooling water pipe 10a. The cooling water heated by the engine is cooled by exchanging heat with the air passing through the radiator 6. In other words, the air passing through the radiator 6 is heated by the cooling water flowing through the radiator 6.

[0017] The fan 7 promotes the heat exchange of the radiator 6 by allowing outside air to pass through the radiator 6. Specifically, the fan 7 draws in the air in front of the radiator 6 and discharges it to the rear of the radiator 6. The fan 7 in the present embodiment is realized by an axial-flow fan. The fan 7 moves the air around the blade 7a axially rearward parallel to the rotation axis of the blade 7a as the blade 7a rotates. Since the fan 7 is an axial-flow fan, the flow velocity of the air flowing through the radially outer region of the rotation axis in the blade 7a is greater than the flow velocity of the air flowing through the radially inner region in the blade 7a.

[0018] The fan 7 is arranged adjacent to the radiator 6 in the front-rear direction. More specifically, the fan 7 is arranged inside the outer edge of the radiator 6 in a front view. The rotation axis of the blade 7a of the fan 7 is located at the central position in the front-rear direction and the up-down direction of the radiator 6. A number of slits are provided in the fan cover 8. The air (fan exhaust air) that has passed through the radiator 6 by the fan 7 flows rearward through the slits of the fan cover 8. Among the radiator 6, the fan outer portion that is radially outside the rotation region of the blade 7a may be configured such that air passes rearward by the traveling wind. By providing the fan 7, even when the vehicle 1 is in a stopped state or a low-speed traveling state, the temperature rise of the engine can be suppressed.

[0019] The vehicle 1 further has an air guide 9 arranged behind the fan 7. The air guide 9 is arranged at an interval rearward with respect to the fan 7 and at an interval forward with respect to the partition wall 2. In other words, the air guide 9 is arranged downstream in the flow direction of the air moved by the fan 7 with respect to the radiator. The air guide 9 is also arranged inside the vehicle width direction between the two suspensions 5. The air guide 9 guides the fan exhaust air in a desired direction so that the fan exhaust air moves away from the partition wall 2. Specifically, the air guide 9 deflects the fan exhaust air flowing rearward outward in the vehicle width direction. Details and functions of the air guide 9 will be described later.

[0020] Figure 2 shows a front view of vehicle 1. In Figure 2, the front wheels 4, radiator 6, fan cover 8, front grille 18, and arm 15 are omitted compared to Figure 1. Also, in Figure 2, the right suspension 5 and the left half of the fan 7 are omitted.

[0021] Vehicle 1 has a body frame 17, which is the framework of vehicle 1. Components such as partition walls 2 and air guides 9 are fixed to the body frame 17.

[0022] The partition wall 2 has a first portion 20 containing a metal material and a second portion 21 containing a resin molding material. In Figure 2, the first portion 20 is located on the lower side of the partition wall 2, and the second portion 21 is located on the upper side of the partition wall 2. In this embodiment, the upper edge 20b of the first portion 20 and the lower edge 21a of the second portion 21 overlap in the front-rear direction. The lower edge 21a of the second portion 21 is located in front of the upper edge 20b of the first portion 20. Because the lower portion of the partition wall 2 is relatively close to the front wheels 4, obstacles such as stones kicked up by the front wheels 4 while the vehicle 1 is in operation are likely to collide with this lower portion. In this embodiment, since the lower portion, i.e., the first portion which is relatively stronger than the resin material, is made of a metal material, damage to the partition wall 2 due to collisions with objects outside the area is suppressed. In addition, when the vehicle 1 is traveling on an unpaved road, the partition wall 2 may be struck by objects other than those kicked up by the wheels, such as rocks or fallen trees on the road surface. Even in this case, the lower part of the partition wall 2 is made of the first part 20 of the metal material, which prevents protrusions on the road surface from penetrating the partition wall 2.

[0023] Furthermore, as shown in Figure 1, the partition wall 2 is inclined backward as it extends outward in the vehicle width direction. Specifically, the partition wall 2 is inclined backward as it extends outward in the vehicle width direction in the region outside the vehicle width direction relative to both ends of the air guide 9 in the vehicle width direction.

[0024] The partition wall 2 further has a plurality of segments 23 in the center of the second portion 21 in the vehicle width direction. In this embodiment, the partition wall 2 has an upper first segment 23a and a lower second segment 23b. The first segment 23a and the second segment 23b contain a resin molding material. The air guide 9 is also fixed to the second segment 23b. The segment may be divided into a right side and a left side. The segment may also consist of three or more segments.

[0025] In the width direction of the vehicle, a tunnel opening 20a is provided in the center of the first section 20, which penetrates the first section 20 in the longitudinal direction. The tunnel opening 20a communicates with a tunnel 13 (see Figure 4) that houses the propeller shaft 12, engine, etc. of the vehicle 1.

[0026] Furthermore, as shown in Figure 1, the partition wall 2 has a support portion 24 that supports a tank 11, which is one of the vehicle components. The tank 11 is a resin container that holds a liquid such as brake fluid. In this embodiment, the support portion 24 is provided on the right side of the partition wall 2, and the tank 11 is placed on the support portion 24 and fixed to the support portion 24. The support portion 24 is also provided in the second portion 21 of the partition wall 2. The air guide 9 is positioned in front of the support portion 24. The support portion 24 may also be provided on the left side of the partition wall 2.

[0027] Referring to Figure 2, the fan 7 has a cylindrical hub 7b having the axis of rotation of the fan 7, a plurality of blades 7a extending radially from the hub 7b, and an outer frame 7c connecting the plurality of blades 7a at their radially outer ends. Here, the fan diameter refers to twice the distance from the center of the hub 7b to the outer frame 7c. In another embodiment, if the fan does not have an outer frame, the fan diameter refers to twice the distance from the center of the hub 7b to the radially outer ends of the blades 7a.

[0028] In a front view, the air guide 9 overlaps with at least a portion of the fan 7. In this embodiment, in a front view, the air guide 9 overlaps with the hub 7b of the fan 7. The air guide 9 also overlaps with the upper and lower ends of the fan 7, respectively, in a front view. In this embodiment, a portion of the fan 7 is located outward in the vehicle width direction relative to the air guide 9 in a front view. Specifically, the outer end of the fan 7 in the vehicle width direction is located outward in the vehicle width direction relative to the air guide 9. More specifically, the upper portion of the fan 7 that is outward in the vehicle width direction is located outward in the vehicle width direction relative to the air guide 9.

[0029] In this embodiment, both ends 90 of the air guide 9 in the vehicle width direction, i.e., a portion of both edges in the vehicle width direction, are located outward in the vehicle width direction at the same height as both ends of the fan 7 in the vehicle width direction. In other words, the air guide 9 has an outer portion 90a (see dotted line portion in Figure 2) that is located outward in the vehicle width direction relative to both ends of the fan 7 in the vehicle width direction. In this embodiment, in the region below the air guide 9 and the fan 7, both ends 90 of the air guide 9 are located outward in the vehicle width direction relative to both ends of the fan 7, i.e., the outer frame 7c. That is, the outer portion 90a of the air guide 9 corresponds to the lower portion of both ends 90. In another embodiment, the outer portion 90a may be provided over the vertical length of both ends 90 of the air guide 9. Here, "both ends 90 of the air guide 9 are located outward in the vehicle width direction relative to both ends of the fan 7" also includes the case where both ends 90 of the air guide 9 overlap with both ends of the fan 7 in a front view.

[0030] Furthermore, when considering a configuration in which the fan does not have an outer frame, the outer portion 90a of the air guide 9 is located outward in the vehicle width direction at the same height as both ends of a virtual circle in the vehicle width direction with the fan diameter as its diameter and the center of the fan diameter as its center. Also, as in this embodiment, when the centers of the fan 7 and the air guide 9 coincide in the vehicle width direction, it is preferable that the maximum width of the air guide 9 in the vehicle width direction is greater than or equal to the maximum width of the fan 7 in the vehicle width direction (i.e., the fan diameter).

[0031] As shown in Figure 2, both ends 90 of the air guide 9 in the vehicle width direction are inclined outward in the vehicle width direction from the upper end downward. Also, both ends 90 of the air guide 9 are adjacent to the suspension 5 in the vehicle width direction when viewed from the front. In other words, both ends 90 of the air guide 9 extend along the extension direction of the suspension 5. More specifically, both ends 90 of the air guide 9 extend along the extension direction when the suspension 5 is extended.

[0032] Furthermore, the upper end of the air guide 9 is adjacent to the upper end of the suspension 5 in the vehicle width direction when viewed from the front. In other words, the air guide 9 occupies as much of the roughly triangular area defined between the two suspensions 5 when viewed from the front as possible.

[0033] Figure 3 is a front view of vehicle 1, with the suspension 5, fan 7, and air guide 9 omitted from Figure 2, and partially showing the area around the divided section 23 of the partition wall 2. In Figure 3, the outer shape of the air guide 9 is depicted as an imaginary line.

[0034] The divided body 23 is provided with two through-holes 22 that penetrate the partition wall 2, i.e., the divided body 23, in the front-to-back direction. The through-holes 22 communicate with the tunnel 13. Cooling water pipes 10a, which are one of the passing bodies 10 that extend in the front-to-back direction within the tunnel 13, pass through the through-holes 22. More specifically, a cooling water pipe 10a going from the engine to the radiator 6 and a cooling water pipe 10a going from the radiator 6 to the engine each pass through the through-holes 22. The air guide 9 is positioned to cover at least one of the multiple through-holes 22. In this embodiment, the air guide 9 is positioned to cover the through-hole 22 through which the cooling water pipe 10a passes from the front.

[0035] In addition to the illustrated through-hole 22, other through-holes are provided for other passing elements 10, such as the steering shaft and harness. The steering shaft is connected to a handle located in the passenger compartment V1. The steering shaft extends from the passenger compartment V1 to the front compartment V2 and passes through a through-hole that penetrates the partition wall 2. The harness is connected to electrical components such as a fan 7 located in the front compartment V2, passes through a through-hole that penetrates the partition wall 2, and extends to the rear.

[0036] Figure 4 is a cross-sectional view of vehicle 1 perpendicular to the vehicle width direction. Specifically, Figure 4 is a cross-sectional view along the cross-sectional line IV-IV that passes through the center of the right-side through-hole 22 shown in Figure 3 and extends in the vertical direction. Figure 4 shows a cooling water pipe 10a, one end of which is connected to the radiator 6, passing through the through-hole 22 and extending into the tunnel 13.

[0037] In this embodiment, the cooling water pipe 10a is a rubber hose. The portion of the cooling water pipe 10a that passes through the through hole 22 is covered with a protective cover 10b. The protective cover 10b is, for example, a cylindrical rigid rubber member. By covering the cooling water pipe 10a with the protective cover 10b, the cooling water pipe 10a is prevented from coming into contact with the upper and lower divided body 23. This prevents the cooling water pipe 10a from being damaged by contact with the divided body 23 and prevents the cooling water from leaking out of the cooling water pipe 10a. The protective cover 10b also passes through the through hole 22, and is therefore one of the passing bodies 10.

[0038] The first divided body 23a and the second divided body 23b are in contact with the protective cover 10b, which is the passing body 10, and sandwich the protective cover 10b in the vertical direction. There does not need to be a gap between the two divided bodies 23a and 23b and the protective cover 10b.

[0039] As shown in Figure 4, the second segment 23b has a projection 23b1 that protrudes forward. The air guide 9 is fixed to the second segment 23b by fastening the bottom wall portion 99 of the air guide 9 to the projection 23b1 of the second segment 23b with bolts or the like.

[0040] The tunnel 13 is located below the center of the passenger compartment V1 in the vehicle width direction. The tunnel 13 is separated from the passenger compartment V1 by the floor panel 19, which is the bottom surface of the passenger compartment V1. The engine of the vehicle 1 is located at the rear of the tunnel 13. The propeller shaft 12 that drives the front wheels 4 and the rear wheels extends in the longitudinal direction within the tunnel 13.

[0041] Figure 5 shows a front view of the air guide 9 according to this embodiment. The air guide 9 is a plate-shaped member. The air guide 9 has a vehicle width inclined portion 91 that slopes outward in the vehicle width direction from the front end towards the rear. In Figure 5, the area indicated by the dots is the vehicle width inclined portion 91.

[0042] Figure 6 shows a cross-sectional view of the air guide 9, cut along the cross-sectional line VI-VI passing through the air collection section 95 of the air guide 9, as seen from above. In Figure 6, the partition wall 2 is also partially shown to illustrate the positional relationship between the partition wall 2 and the air guide 9. The vehicle width inclined sections 91 are arranged in pairs, left and right. The left and right vehicle width inclined sections 91 are arranged symmetrically on the left and right sides with respect to a virtual plane that passes through the rotation axis of the fan 7 and extends in the front-rear and up-down directions. In a front view, the right vehicle width inclined section 91 is inclined to the right in the vehicle width direction from the front end towards the rear. Therefore, the fan exhaust air that passes to the right of the fan 7's rotation axis is guided to the right in the vehicle width direction along the right vehicle width inclined section 91. In a front view, the left vehicle width inclined section 91 is inclined to the left in the vehicle width direction from the front end towards the rear. Therefore, the fan exhaust air that passes to the left of the fan 7's rotation axis is guided to the left in the vehicle width direction along the left vehicle width inclined section 91. The vehicle width inclined portion 91 is formed from the upper end to the lower end of the air guide 9. The vehicle width inclined portion 91 may also be formed in part of the air guide 9. When the air guide 9 is installed on the vehicle 1, it is preferable that the vehicle width inclined portion 91 is inclined rearward at an inclination angle θ1 in the range of 15 degrees to 75 degrees with respect to the vehicle width direction.

[0043] The air guide 9 has a return portion 93 that extends from the outer end of the vehicle width inclined portion 91 in the vehicle width direction, in a direction inclined forward with respect to the inclination direction of the vehicle width inclined portion 91. In this embodiment, as shown in Figure 6, the return portion 93 extends parallel to the vehicle width direction. The return portion 93 may also be inclined outward in the vehicle width direction toward the front. The return portion 93 may also extend from the outer end of the vehicle width inclined portion 91 in the vehicle width direction, in a direction between the outward direction of the vehicle width inclined portion 91 and the inclination direction of the vehicle width inclined portion 91. The inclination angle between the return portion 93 and the vehicle width direction is set to be smaller than the inclination angle θ2 between the vehicle width direction and the partition wall 2. In other words, the virtual extension line L1 extending along the return portion 93 in the vehicle width direction is set to have a larger dimension in the front-rear direction as it moves outward in the vehicle width direction, relative to the virtual extension line L2 extending along the partition wall 2 in the vehicle width direction.

[0044] Figure 7 shows a cross-sectional view of the air guide 9 cut along the cross-sectional line VII-VII, which is the center of the air guide 9 in the vehicle width direction. The air guide 9 has a vertically inclined portion 94 that inclins in one direction vertically or horizontally from the front end toward the rear. In this embodiment, the vertically inclined portion 94 has a downwardly inclined portion 94a that inclins downward toward the rear and an upwardly inclined portion 94b that inclins upward toward the rear. The downwardly inclined portion 94a is inclined downward toward the rear at an inclination angle θ3. The downwardly inclined portion 94a is located within the upper half of the air guide 9. The upwardly inclined portion 94b is inclined upward toward the rear at an inclination angle θ4. The upwardly inclined portion 94b is located below the downwardly inclined portion 94a and is located within the lower half of the air guide 9. In this embodiment, the downwardly inclined portion 94a and the upwardly inclined portion 94b are inclined outward toward the rear in the vehicle width direction and are therefore also vehicle width inclined portion 91. In other words, the upward inclined portion 94b is formed in the upper region of the pair of left and right vehicle width inclined portions 91. The downward inclined portion 94a is formed in the lower region of the pair of left and right vehicle width inclined portions 91.

[0045] The air guide 9 further has an air collection section 95 located between the downward-sloping section 94a and the upward-sloping section 94b in the vertical direction. The air collection section 95 is the part where the fan exhaust air guided downward by the downward-sloping section 94a and the fan exhaust air guided upward by the upward-sloping section 94b converge. In this embodiment, the air collection section 95 corresponds to the region along the upper edge of the upward-sloping section 94b. That is, the air collection section 95 is also a vehicle width inclined section 91. Note that the air guide 9 may have only one of the downward-sloping section 94a or the upward-sloping section 94b.

[0046] Figure 8 is a side view of vehicle 1, with some parts omitted. Referring to Figures 2 and 8, the air collection section 95 is located above the upper edge 20b of the first section 20. "The air collection section 95 is located above the upper edge 20b of the first section 20" also means "the air collection section 95 overlaps with the upper edge 20b of the first section 20 in a front view" and "the air collection section 95 is located partially above the upper edge 20b of the first section 20".

[0047] The air guide 9 has a vertical section 98 that connects the downward inclined section 94a and the air collecting section 95. The vertical section 98 is a surface perpendicular to the horizontal direction (front-rear - left-right direction). The vertical section 98 is also inclined outward in the vehicle width direction toward the rear, and is therefore a vehicle width inclined section 91. In this embodiment, the return section 93 is connected to the outer ends in the vehicle width direction of a part of the upward inclined section 94b, the air collecting section 95, and a part of the vertical section 98. As shown in Figures 2 and 8, the vertical section 98 is located above the upper edge 20b of the first section 20.

[0048] The air guide 9 further has a pipe avoidance section 97 to avoid the cooling water pipes 10a. The pipe avoidance section 97 is curved in a convex shape toward the vehicle width direction according to the layout of the cooling water pipes 10a. The aforementioned bottom wall section 99 extends forward from the lower end of the pipe avoidance section 97 and the upward inclined section 94b (see also Figure 4).

[0049] Referring to Figure 3, the through-hole 22 is shielded from the front by the air guide 9. Specifically, the through-hole 22 is covered by the upward inclined portion 94b of the air guide 9. That is, a part of the upward inclined portion 94b is a shielding portion 96 that covers the through-hole 22 from the front. Depending on the position of the through-hole 22, the shielding portion 96 may also be located in other areas of the air guide 9, such as the downward inclined portion 94a, the return portion 93, the vertical portion 98, etc.

[0050] Next, the airflow in vehicle 1 according to this embodiment will be described.

[0051] In Figure 1, an example of airflow is indicated by the symbol F. Air located in front of the radiator 6 is drawn into the radiator 6 by the operation of the fan 7, and flows backward through the radiator 6, fan 7, and fan cover 8. As the air passes through the radiator 6, it is heated by exchanging heat with the coolant pipes 10a inside the radiator 6. Therefore, the temperature of the air flowing backward after passing through the fan 7, i.e., the fan exhaust air, is higher than the ambient temperature.

[0052] If the fan exhaust air flowing to the rear collides with partition wall 2, the temperature of partition wall 2 will rise. If partition wall 2 is made of metal, its thermal conductivity is higher than if partition wall 2 is made of resin molding material, so the temperature rises more easily. The temperature rise of partition wall 2 will result in radiant heat being emitted from partition wall 2. In this case, it will cause a temperature rise in the passenger space V1 located behind partition wall 2, thus compromising the comfort of the passenger space V1.

[0053] In this embodiment, the fan exhaust air that has passed through the fan 7 collides with the rear air guide 9. Specifically, the fan exhaust air collides with the vehicle width inclined portion 91 of the air guide 9 and flows outward in the vehicle width direction towards the rear, along the vehicle width inclined portion 91. Subsequently, the direction of the fan exhaust air flow is changed away from the partition wall 2 by the return portion 93 extending from the vehicle width outer end of the vehicle width inclined portion 91. As a result, the fan exhaust air moves away from the partition wall 2 in the vehicle width direction and outward. Therefore, the fan exhaust air is guided by the air guide 9 in a direction away from the partition wall 2 in the vehicle width direction and outward. This suppresses the fan exhaust air from colliding with the partition wall 2, and thus suppresses the temperature rise of the partition wall 2, i.e., the temperature rise of the passenger space V1.

[0054] Figure 6 shows a virtual extension line L3 that extends outward in the vehicle width direction along the vehicle width inclined section 91. The portion of the virtual extension line L3 that faces the partition wall 2 in the longitudinal direction is located in front of the partition wall 2. In other words, the virtual extension line L3 does not intersect with the partition wall 2. Therefore, the fan exhaust air flowing along the vehicle width inclined section 91 is less likely to collide with the partition wall 2.

[0055] Furthermore, as shown in Figure 1, both ends 90 of the air guide 9 are located rearward relative to the suspension 5. Therefore, the fan exhaust air flowing outward in the vehicle width direction from both ends 90 can flow between the suspension 5 and the partition wall 2 without being obstructed by the suspension 5.

[0056] The air guide 9 also guides the fan exhaust air away from the support 24 and the tank 11 in the direction outward in the vehicle width direction. In this embodiment, since the air guide 9 is positioned in front of the support 24 and the return portion 93 extends outward in the vehicle width direction, the fan exhaust air is less likely to collide with the support 24. Therefore, the temperature rise of the tank 11 can be suppressed.

[0057] Referring to Figures 5 and 7, as described above, the fan exhaust air is guided vertically by the upward-sloping section 94b and the downward-sloping section 94a to collect in the air collection section 95, and then guided outward in the vehicle width direction along the air collection section 95. As a result, the airflow velocity of the fan exhaust air in the air collection section 95 becomes relatively large, allowing the fan exhaust air to flow vigorously outward in the vehicle width direction. Consequently, the fan exhaust air can more easily acquire inertial force, thus suppressing collision of the fan exhaust air with the rear partition wall 2 and support section 24. Furthermore, since a return section 93 is provided on the outside of the air collection section 95 in the vehicle width direction, more fan exhaust air can be guided away from the partition wall 2. Note that even if the air guide 9 has only one of the downward-sloping section 94a or the upward-sloping section 94b, the fan exhaust air can collect either upward or downward and flow vigorously outward in the vehicle width direction.

[0058] Furthermore, as described above, since the air collection section 95 is located above the upper edge 20b of the first section 20, the main flow of fan exhaust air along the air collection section 95 can be generated above the first section 20. For this reason, the fan exhaust air is less likely to collide with the first section 20. As a result, the temperature rise of the first section 20, which has a higher thermal conductivity than resin, can be suppressed, and thus the temperature rise of the passenger space V1 can be further suppressed.

[0059] Furthermore, as described above, since the outer portion 90a of the air guide 9 is located outward in the vehicle width direction at the same height as both ends of the fan 7, the fan exhaust air, which has width in the vehicle width direction, can be guided as far as possible in the desired direction by the air guide 9. In particular, since the outer portion 90a is located in the area below the air guide 9, that is, in the area close to the first portion 20, the fan exhaust air is less likely to collide with the first portion 20. In other words, the fan exhaust air is guided away from the second portion 21 and the first portion 20 of the partition wall 2 in the direction away from the vehicle width direction, but it is more easily guided in that direction from the first portion 20.

[0060] Furthermore, as described above, since the vertical section 98 is located above the upper edge 20b of the first section 20, the fan exhaust air that collides with the vertical section 98 and flows outward in the vehicle width direction is also less likely to collide with the first section 20.

[0061] In a wide range of directions in the vehicle width and vertical direction, it is preferable that the fan exhaust air is guided by the air guide 9. That is, it is preferable that the area of ​​the air guide 9 in a front view be larger. In this embodiment, in a front view, both left and right ends 90 of the air guide 9 are aligned with the extension direction of the left and right suspensions 5, and the upper end of the air guide 9 is adjacent to the upper end of the suspension 5, so the area of ​​the air guide 9 can be made larger.

[0062] Furthermore, since the thermal conductivity of the second part 21, which includes the resin molding material, is lower than that of the first part 20, the temperature of the second part 21 is less likely to rise compared to the first part 20. In this embodiment, as shown in Figure 2, a support part 24 is provided on the second part 21. Therefore, even if the fan exhaust air partially hits the second part 21, the temperature rise of the second part 21 is relatively small, and the temperature of the support part 24 is less likely to rise. As a result, the temperature rise of the liquid in the tank 11, which is one of the in-vehicle components located on the support part 24, can be suppressed.

[0063] If the fan exhaust air flows into the tunnel 13, it may come into contact with the cooling water pipe 10a extending inside the tunnel 13 and heat the cooling water pipe 10a. This may reduce the cooling effect of the engine and other components. For this reason, it is preferable that the fan exhaust air does not flow into the tunnel 13.

[0064] As shown in Figure 4, the through-hole 22 communicating with the tunnel 13 has a passage body 10 passing through it, and the two divided bodies 23a and 23b sandwich the passage body 10, so the fan exhaust air does not easily flow from the through-hole 22 into the tunnel 13. Furthermore, since the second divided body 23b protrudes forward above the tunnel opening 20a communicating with the tunnel 13, the flow of fan exhaust air toward the tunnel opening 20a may be obstructed by the protruding portion 23b1. For this reason, the fan exhaust air does not easily flow from the tunnel opening 20a into the tunnel 13. Accordingly, according to the configuration of this embodiment, the reduction in the cooling effect of the engine, etc. caused by fan exhaust air can be suppressed.

[0065] Furthermore, since the air guide 9 has a shielding portion 96, that is, the air guide 9 covers the through hole 22 from the front, it is possible to prevent the fan exhaust air from flowing into the gap between the through hole 22 and the through body 10 passing through the through hole 22. This prevents hot air from entering the passenger space V1 and prevents the temperature inside the passenger space V1 from rising.

[0066] Furthermore, while vehicle 1 is in motion, sufficient airflow separate from the air that passes through radiator 6 flows into the front space V2, thus suppressing the temperature rise within the front space V2.

[0067] On the other hand, in so-called idling conditions where the vehicle is stopped with the engine running, or in high-load slow-speed conditions such as driving slowly on a steep slope, the airflow rate of the air passing through the front space V2 is low. In this case, compared to driving conditions, the air that has passed through the radiator 6 tends to remain in the front space V2, causing the temperature inside the front space V2 to rise easily. In this embodiment, the air guide 9 guides the air that has passed through the radiator 6 outward in the vehicle width direction. In other words, the air guide 9 deflects the air that has passed through the radiator 6 and guides it away from the partition wall 2. This prevents the air that has passed through the radiator 6 from colliding with the partition wall 2, especially the first part 20 which includes metal material. As a result, the radiant heat emitted from the first part 20 due to the temperature rise of the partition wall 2 can be suppressed. This prevents the radiant heat from the partition wall 2 from reaching the passenger space V1, thereby preventing the temperature of the passenger space V1 from rising.

[0068] The off-road vehicle 1 according to this embodiment provides the following effects.

[0069] (1) Off-road vehicle 1 is, The passenger compartment V1 where the occupants are located, In front of the passenger compartment V1 is a front space V2 that houses onboard components, A partition wall 2 separates the passenger space V1 and the front space V2, The radiator 6 is located in the front space V2, In the front space V2, a fan 7 draws in air from the front of the radiator 6 and expels it to the rear, In the front space V2, an air guide 9 is positioned behind the fan 7 and at a distance forward from the partition wall 2, and guides the fan exhaust air that has passed through the radiator 6 by the fan 7 away from the partition wall 2 in the direction outward in the vehicle width direction. It is equipped with.

[0070] As a result, the fan exhaust air can be prevented from colliding with the partition wall 2, thereby suppressing the temperature rise of the partition wall 2, and thus the temperature rise of the passenger space V1.

[0071] (2) The partition wall 2 has a first part 20 which includes a metal material, The air guide 9 guides the fan exhaust air away from the first section 20 in the direction away from the vehicle width.

[0072] As a result, the temperature rise of the first part 20, which has a higher thermal conductivity than resin, can be suppressed, further suppressing the temperature rise of the passenger space V1.

[0073] (3) The air guide 9 is The fan 7 has a diameter equal to the fan diameter, and an outer portion 90a is located at the same height as the outer end of a virtual circle centered on the center of the fan diameter, with respect to both ends in the vehicle width direction.

[0074] As a result, the fan exhaust air, which has a width in the vehicle width direction, can be guided in the desired direction by the air guide 9.

[0075] (4) The air guide 9 has a vehicle width inclined portion 91 that is inclined outward in the vehicle width direction toward the rear.

[0076] As a result, the fan exhaust air is guided along the vehicle width inclined section 91, which prevents the fan exhaust air from colliding with the partition wall 2.

[0077] (5) Of the virtual extension line L3 that extends outward in the vehicle width direction along the vehicle width inclined section 91, the portion that faces the partition wall 2 in the front-rear direction is located in front of the partition wall 2.

[0078] As a result, the fan exhaust air flowing along the vehicle width inclined section 91 is less likely to collide with the partition wall 2.

[0079] (6) The air guide 9 has a return portion 93 that extends from the outer end of the vehicle width inclined portion 91 in the vehicle width direction in a direction that is inclined forward with respect to the inclination direction of the vehicle width inclined portion 91.

[0080] As a result, the fan exhaust air flows along the return section 93, further suppressing collision of the fan exhaust air with the partition wall 2.

[0081] (7) The air guide 9 has a vertically inclined portion 94 that is inclined in one direction vertically toward the rear.

[0082] The fan exhaust air is guided upward or downward by the vertically inclined section 94, allowing the fan exhaust air to be concentrated and directed outward in the vehicle width direction. As a result, the fan exhaust air flows vigorously outward in the vehicle width direction, suppressing collision with the partition wall 2.

[0083] (8) The air guide 9 has a downward inclined portion 94a that slopes downward toward the rear, an upward inclined portion 94b located below the downward inclined portion 94a and slopes upward toward the rear, and an air collecting portion 95 located between the downward inclined portion 94a and the upward inclined portion 94b in the vertical direction.

[0084] As a result, the fan exhaust air is guided vertically by the upward-sloping section 94b and the downward-sloping section 94a, and collects in the air collection section 95, where it is guided along the air collection section 95. This guides the fan exhaust air even more forcefully outward in the vehicle width direction, further suppressing collision with the partition wall 2.

[0085] (9) The air guide 9 has a return portion 93 that is inclined forward with respect to the extension direction of the air collecting portion 95, extending from the outer end of the air collecting portion 95 in the vehicle width direction.

[0086] As a result, more fan exhaust air can be directed away from partition wall 2.

[0087] (10) The partition wall 2 has a first part 20 which includes a metal material, The air collection section 95 is located above the upper edge 20b of the first section 20.

[0088] As a result, collisions with the first portion 20 of the fan exhaust are further suppressed, thus further reducing the temperature rise in the passenger compartment V1.

[0089] (11) Both ends 90 of the air guide 9 in the vehicle width direction are located rearward with respect to the suspension 5 connected to the front wheels 4 of the off-road vehicle 1.

[0090] As a result, the fan exhaust air flowing outward in the vehicle width direction from both ends 90 can flow in the desired direction without being obstructed by the suspension 5.

[0091] (12) Both ends 90 of the air guide 9 in the vehicle width direction extend along the suspension 5 connected to the front wheels 4 of the off-road vehicle 1.

[0092] As a result, the area of ​​the air guide 9 in a front view can be increased, so that the fan exhaust air can be guided by the air guide 9 over a wide area in both the width and vertical directions of the vehicle.

[0093] (13) The partition wall 2 is provided with a through hole 22 that penetrates the partition wall 2 in the front-to-back direction, The air guide 9 has a shielding portion 96 that covers the through hole 22 from the front.

[0094] As a result, the flow of fan exhaust air toward the through-hole 22 can be suppressed, thus preventing fan exhaust air from flowing into the tunnel 13 connected to the through-hole 22. This prevents the cooling water pipe 10a extending through the tunnel 13 from being heated by the fan exhaust air. Furthermore, the temperature rise in the passenger space V1 through the tunnel 13 can also be suppressed.

[0095] (14) The partition wall 2 has a plurality of divided parts 23, The multiple segmented bodies 23 come into contact with the passing body 10 as it passes through the through hole 22, sandwiching the passing body 10 between them.

[0096] As a result, the fan exhaust air does not easily flow into the tunnel 13 through the through-hole 22.

[0097] (15) The partition wall 2 has a support portion 24 that supports the tank 11 for containing liquid, The air guide 9 is positioned inward in the vehicle width direction relative to the support portion 24 and guides the fan exhaust air away from the support portion 24 in the vehicle width direction.

[0098] As a result, the fan exhaust air is less likely to collide with the support section 24. This helps to suppress the temperature rise of the tank 11 and thus suppress the deterioration of the liquid inside the tank 11.

[0099] (16) The partition wall 2 has a first part 20 containing a metal material and a second part 21 containing a resin molding material, The second part 21 has a support portion 24 that supports at least one of the in-vehicle components.

[0100] As a result, since the support portion 24 is provided in the second portion 21, which is relatively less prone to temperature rise, the temperature rise of the liquid in the tank 11, which is one of the in-vehicle components located in the support portion 24, can be suppressed.

[0101] (17) Off-road vehicle 1 is, The passenger compartment V1 where the occupants are located, In front of the passenger compartment V1 is a front space V2 that houses onboard components, A partition wall 2 separates the passenger space V1 and the front space V2, Here, the partition wall 2 has a first part 20 containing a metal material and a second part 21 containing a resin molding material. The second part 21 has a support portion 24 that supports at least one of the in-vehicle components, The radiator 6 is located in the front space V2, In the front space V2, a fan 7 draws in air from the front of the radiator 6 and expels it from the rear. It is equipped with.

[0102] As a result, since the support portion 24 is provided in the second portion 21, which is relatively less prone to temperature rise, the temperature rise of the liquid in the tank 11, which is one of the in-vehicle components located in the support portion 24, can be suppressed.

[0103] (18) Off-road vehicle 1 is, The passenger compartment V1 where the occupants are located, In front of the passenger compartment V1 is a front space V2 that houses onboard components, A partition wall 2 separates the passenger space V1 and the front space V2, Here, the partition wall 2 is provided with a through hole 22 that penetrates the partition wall 2 in the front-to-back direction. The partition wall 2 has multiple divided sections 23, The multiple segmented bodies 23 are in contact with the passing body 10 that passes through the through hole 22, and sandwich the passing body 10 between them. The radiator 6 is located in the front space V2, In the front space V2, a fan 7 draws in air from the front of the radiator 6 and expels it from the rear. It is equipped with.

[0104] As a result, the fan exhaust air is less likely to flow into the tunnel 13 through the through-hole 22, thus suppressing the heating of the cooling water pipe 10a extending inside the tunnel 13 by the fan exhaust air.

[0105] Furthermore, the off-road vehicle 1 described herein is not limited to the configuration of the above embodiment, and various modifications are possible.

[0106] The air guide 9 does not necessarily have a return portion 93. In such an embodiment, the fan exhaust air can still be guided away from the partition wall 2 in the direction outward in the vehicle width direction.

[0107] The divided body 23 may be in direct contact with the cooling water pipe 10a, sandwiching the cooling water pipe 10a. In other words, the protective cover 10b may not be provided.

[0108] A fan shroud may be provided behind the radiator 6 to house the fan 7 and to straighten the airflow. By using both the fan shroud and the air guide 9, it is possible to more reliably suppress the fan exhaust air from being directed towards the partition wall 2.

[0109] The slits provided in the fan cover 8 may be inclined so that they move outward in the vehicle width direction as the fan exhaust air moves towards the rear. This makes it possible to more reliably suppress the fan exhaust air from moving towards the partition wall 2.

[0110] The ends 90 of the air guide 9 may be located at the same height as the ends of the fan 7 in the vehicle width direction, but inward in the vehicle width direction. Even in this configuration, it is possible to suppress the fan exhaust air from being directed toward the partition wall 2. Furthermore, the air guide 9 may be formed to overlap with the entire fan 7 when viewed from the front.

[0111] The air guide 9 does not necessarily have a vertical section 98. That is, the downward-sloping section 94a may be directly connected to the air collection section 95. In this case, the air collection section 95 includes a boundary line between the upward-sloping section 94b and the downward-sloping section 94a. This boundary line is located below the rotation axis of the fan 7. The boundary line is also located below the vertical center position of the air guide 9. The boundary line slopes backward as it moves outward in the vehicle width direction from the center position of the boundary line in the vehicle width direction. Return sections 93 are located on the outside of the boundary line in the vehicle width direction. Fan exhaust air that collides with the upward-sloping section 94b and the downward-sloping section 94a is guided toward the boundary line, respectively. Fan exhaust air guided toward the boundary line is guided backward as it moves outward in the vehicle width direction along the boundary line. Because the return sections 93 are located on the outside of the boundary line in the vehicle width direction, fan exhaust air guided toward the boundary line is guided by the return sections 93 toward away from the partition wall 2.

[0112] The suspension 5 may be positioned so as not to overlap with the air guide 9 in a front view.

[0113] Fan 7 may be positioned in front of radiator 6.

[0114] The radiator 6 may also cool the refrigerant used to cool components other than the engine. For example, if supercharged air is supplied to the engine, the radiator 6 may cool the refrigerant used to cool the supercharged air. Also, if the power source is an electric motor, the radiator 6 may cool the refrigerant used to cool the motor itself or the battery. Furthermore, the radiator 6 may also cool the refrigerant used in the air conditioning system.

[0115] The fan cover 8 does not need to be provided.

[0116] The fan may be a fan other than an axial fan. For example, the fan may be a centrifugal fan. If the fan is an axial fan, the air guide 9 of this disclosure can suitably guide the fan exhaust air in a desired direction.
