Description

TECHNICAL FIELDThe technology disclosed herein belongs to a technical field related to a structure of an engine room of a vehicle and a method of assembling a capsule cover constituting the engine room.BACKGROUND OF THE DISCLOSUREFor improving the heat retaining property of engines, it has conventionally been considered to provide a capsule cover surrounding the engine to an engine room.For example, JP 2019-039 303 A discloses an engine room structure provided with a heat insulating member (capsule cover) consisting of an upper cover part covering an upper part of the engine and a side wall part covering sides of the engine. In this engine compartment structure, a part of the side wall part is composed of intake component(s) of the engine.Recently, devices constituting the vehicle engine are based on an electronic controller, and electrical components including an ECU (Electrical Control Unit) for controlling each device are provided in the vicinity of the engine. The ECU is designed based on semiconductor devices in many cases, and therefore tends to be affected by heat from the motor. Therefore, when these electrical components are disposed inside the capsule cover, the performance of the electrical components may be deteriorated.For this reason, the electrical components are attached to the outside of the capsule cover. However, due to recent demands on downsizing of the vehicle, the capsule cover tends to be located substantially near the member / members constituting / constituting the vehicle body. Therefore, by disposing the electric component(s) only on the outside of the capsule cover, the freedom in disposing the electric component(s) around the capsule cover is reduced.DE 11 2017 000 095 T5 discloses a fixing structure for a heat insulating cover comprising a top wall and first side walls. The top wall covers an upper surface of a motor, which is a surface of an upper portion of the motor. The first side walls cover respective upper portions of both side surfaces of the engine in a vehicle width direction. A portion of the heat insulating cover that is closer to the rear of the vehicle is provided with a hinge mechanism that vertically rotatably supports the upper portion of the heat insulating cover including the upper wall. The upper portion of the heat insulating cover can be rotated with the hinge mechanism as a fulcrum between a closed position in which the motor 1 is shielded and an open position in which the motor is visible.SUMMARY OF THE DISCLOSURETherefore, the technology disclosed herein is provided in view of the above situations, and a purpose thereof is to improve the ability to mount an electric component as much as possible while appropriately cooling the electric component in an engine room with a capsule cover covering the engine.This object is achieved by the features of the independent claims. Further developments are defined in the dependent claims.According to an aspect of the present disclosure, there is provided an engine compartment structure of a vehicle including a capsule cover surrounding an engine. The capsule cover includes a cover part configured to cover the engine from above and at least one side wall part configured to cover the engine from outside in a vehicle width direction. The side wall part is divided into a plurality of vertical walls extending in a substantially up-down direction in a front-rear direction of the vehicle, and one of the plurality of vertical walls is a specific vertical wall to which an electric component is mounted on a side surface part opposite to the engine.According to this structure, since the side wall part is composed of the plurality of vertical walls including the specific vertical wall, the specific vertical wall can be disposed on the motor side after the electric component is attached to the specific vertical wall. Therefore, the electric component can be easily disposed in the engine room in the state where the electric component is mounted outside the capsule cover. Therefore, the capability of mounting the electrical component can be improved as much as possible.Moreover, by disposing the electric component outside the capsule cover, the electric component can also be cooled appropriately.The specific vertical wall is disposed at a position separated from a suspension tower with a gap therebetween in the vehicle width direction. The electrical component is attached to the specific vertical wall such that the electrical component is located between the specific vertical wall and the suspension tower.That is, the traveling wind can easily pass through an area in the engine room between the engine and the suspension tower. Thus, by disposing the electric component between the specific vertical wall and the suspension tower, the cooling efficiency of the electric component can be improved.In addition to the specific vertical wall, the electrical component may also be attached to and supported by the suspension tower.According to this structure, the support rigidity of the electrical component can be increased. Thus, the electric component can be held at the position where the traveling wind easily flows, and as a result, the cooling efficiency of the electric component can be improved.Additional vertical walls of the plurality of vertical walls may be disposed in front of and behind the specific vertical wall, respectively. The specific vertical wall may be attached to the additional vertical walls without being attached to a vehicle body forming member. A fitting part of the specific vertical wall to each of the additional vertical walls may be located in an upper end part of the specific vertical wall.According to this structure, removal of the specific vertical wall becomes easier. Therefore, removal of the electrical component becomes easier as well. As a result, the electric component maintenance capability can also be improved.According to another aspect of the present disclosure, a method of disposing a capsule cover in an engine compartment of a vehicle is provided. The capsule cover includes at least one side wall part configured to surround an engine disposed in the engine compartment and cover side parts of the engine in a vehicle width direction. The side wall part is composed of a plurality of vertical walls extending substantially in an up-down direction. The method includes preparing a sub-assembly by attaching an electric component to a specific vertical wall that is one of the plurality of vertical walls, disposing the sub-assembly after the sub-assembly is prepared so that the electric component is located on the opposite side in the vehicle width direction of the engine with respect to the specific vertical wall, and preferably attaching the electric component to a member constituting a vehicle body after the sub-assembly is disposed.According to this structure, after the electric component is attached to the specific vertical wall in advance, the electric component can be attached to and supported by the vehicle body forming member together with the specific vertical wall. Therefore, the capability of mounting the electrical component can be improved.Moreover, by disposing the electric component outside the capsule cover, the electric component can also be cooled appropriately.Disposing the sub-assembly includes disposing the specific vertical wall such that the electrical component is located between the specific vertical wall and a suspension tower in the vehicle width direction. The attaching of the electric component may include attaching the electric component to an upper surface part of the suspension tower.According to this structure, because the electric component is attached to the upper surface part of the suspension tower, attachment to the vehicle is easy. Therefore, the capability of mounting the electrical component can be improved.Moreover, since the electric component is located in the region between the specific vertical wall and the suspension tower through which the traveling wind easily flows, the cooling efficiency of the electric component can be improved.The engine compartment structure may further include a rear wall part configured to cover the engine from behind. The side wall part may include a first vertical wall extending from a front end part of the side wall part to the vicinity of a suspension tower disposed on the left side of the vehicle, a second vertical wall disposed to oppose the left suspension tower with a gap therebetween, and a third vertical wall extending substantially rearward from a rear end part of the second vertical wall and integrated with the rear wall part. The specific vertical wall may be the second vertical wall.The electrical component may be a powertrain control module, and the powertrain control module may include a plurality of ribs extending left and right. The specific vertical wall may be provided, at a tip end part of a protrusion thereof, with an engagement part configured to engage with an engagement hole formed in a bracket to which the electrical component is attached. The drive train control module (electric component) may be mounted on the specific vertical wall by engaging the engaging part with the engaging hole of the bracket.BRIEF DESCRIPTION OF THE DRAWINGSFIG. 1 is a plan view illustrating a front part of a vehicle to which an engine compartment structure according to an embodiment is applied, as viewed from above.

Note that in the following description, "front", "rear", "left", "right", "upper", and "lower" of a vehicle 1 are simply referred to as "front", "rear", "left", "right", "upper", and "lower", respectively. Note that the term "outward / outward" or "outward" or "outer side" as used herein refers to outward / outward in the vehicle width direction with respect to the center line extending in the longitudinal direction of the vehicle, and the term "inward / inward" or "inward" or "inner side" as used herein refers to inward / inward in the vehicle width direction with respect to the center line.FIG. 1 schematically shows a front part of the vehicle 1 on which an engine room ER is provided. In the front part of the vehicle 1, a pair of left and right front side frames 3 extending substantially in the front-rear direction are disposed in front of a dash panel, and between the left and right front side frames 3, the engine room ER is formed in which an engine (not illustrated) that drives the front wheels (not illustrated) of the vehicle 1 and a transmission (not illustrated) are disposed. For example, the engine is longitudinally oriented within the engine room ER, and the transmission is disposed behind the engine.Each pair of left and right front side frames 3 has a substantially rectangular closed cross section. As illustrated in FIG. 9, a rear part of each front side frame 3 is a kick part in which the height gradually decreases rearward. In the front-rear direction, a partition wall 4 (see FIG. 2 ) partitioning the engine room ER from a cabin is provided at substantially the same position as the kick part.A pair of left and right apron reinforcements 16 extending substantially in the front-rear direction are disposed above the front side frames 3. Each apron reinforcement 16 is located outside the corresponding front side frame 3 in the vehicle width direction. A front end part of each front side frame 3 and a front end part of the corresponding apron reinforcement 16 are coupled to each other by a front frame coupling part (not illustrated) extending substantially in the up-down direction.An outer side wall part of each front side frame 3 and an inner side wall part of the corresponding apron reinforcement 16 are coupled by a suspension tower 30. Each suspension tower 30 bulges inward in the vehicle width direction of the corresponding apron reinforcement 16 (i.e., on the engine compartment EB side). As illustrated in FIGS. 4 and 9, each suspension tower 30 includes an annular upper part 31 to which an upper end of a front cushion is attached or attachable, and a partially cylindrical peripheral wall 32 extending substantially downward from the peripheral edge of the upper part 31, specifically, on the engine compartment EB side (i.e., inward in the vehicle width direction). A lower end part of the upper part 31 and an upper end part of the peripheral wall 32 are welded to each other. The outer side part of the upper part 31 is welded to the corresponding skirt reinforcement 16. A lower end part of the peripheral wall 32 is welded to the corresponding front side frame 3.A cowl member 10 extending in the vehicle width direction is provided above the dash panel 4. At a position corresponding to each of the left and right end parts of the cowl member 10, a front hinge pillar 11 for rotatably supporting a front door (not illustrated) of the vehicle 1 is provided.A capsule cover 50 surrounding the periphery of the engine disposed in the engine room ER is provided to the engine room ER. As illustrated in FIGS. 1 and 2, the capsule cover 50 includes a lid part 51 (the broken line in FIG. 1 ) covering the engine from above, a support wall part 53 covering the engine from above and supporting a rear part of the lid part 51, a left side wall part 60 covering the left side of the engine from outside in the vehicle width direction, a right side wall part 70 covering the right side of the engine from outside in the vehicle width direction, and a rear wall part 52 (see FIG. 2, etc.) covering the rear side of the engine. As will be described in detail later, the left and right side wall parts 60 and 70 are each divided into a plurality of vertical walls, and the rearmost vertical walls (a third vertical wall 63 and a sixth vertical wall 73 described later) are preferably formed integrally with the rear wall part 52. Each of the wall parts 51, 52, 53, 60, and 70 is composed of a plate member made of resin as an outer skin and a heat insulating member made of glass wool or urethane which is integrally arranged with the plate member.As shown in FIG. 1, the support wall part 53 is provided with a pair of support parts 53 aseparated leftward and rightward. The pair of support parts 53 a pivotably supports a rear end part of the lid part 51. thus, the lid part 51 is pivotable using the support parts 53 aas pivot points. As a result, the motor can be visually inspected when the lid part 51 is opened, and therefore the ability to service the motor improves.As illustrated in FIGS. 1 and 2, the capsule cover 50 according to this embodiment is not symmetrical in the vehicle width direction, and the left side wall part 60 and the right side wall part 70 have different structures. Hereinafter, each structure will be described in detail.As illustrated in FIGS. 2 and 3, the left side wall part 60 is divided into three vertical walls extending substantially in the up-down direction. In detail, it includes a first vertical wall 61 extending from a front end part of the left side wall part 60 to the vicinity of the left suspension tower 30, a second vertical wall 62 disposed to oppose the left suspension tower 30 with a gap S therebetween, and the third vertical wall 63 extending substantially rearward from a rear end part of the second vertical wall 62 and preferably integrated with the rear wall part 52.As shown in FIGS. 1 to 3, the first vertical wall 61 extends from front to rear so as to be inclined leftward. In the first vertical wall 61, a heat insulating member is attached to a right surface of a first plate member 61 amade of resin. A rear end portion of the first plate member 61 aincludes a first sealing means 61 bfor filling a gap with the second vertical wall 62. As shown in FIG. 3, the first sealing means 61 bextends leftward and inclines forward. Although illustration is omitted, the first vertical wall 61 is fastened to the left front side frame 3 at a lower end part with bolts.A comparatively large gap is formed between the left skirt reinforcement 16 and the first vertical wall 61 when viewed from above. An air cleaner 20 is disposed in this gap. As illustrated in FIG. 9, the air cleaner 20 is attached to the first vertical wall 61 through a fitting part 61 c. An air duct 21 for introducing outside air is fixed to the air cleaner 20. Although illustration is omitted, the air duct 21 is fastened to the front frame coupling part by bolts.As illustrated in FIGS. 1 to 3, the second vertical wall 62 is disposed so as to overlap with the left suspension tower 30 in the vehicle width direction. In the second vertical wall 62, a heat insulating member is attached to the right surface of a second plate member 62 amade of resin.As illustrated in FIGS. 2 and 3, while a front end portion 62 bof the second plate member 62 ais located in the left side of the rear end portion of the first vertical wall 61, a rear end portion 62 cof the second plate member 62 ais located in the right side of the rear end portion of the third vertical wall 63. the rear end portion 62 cof the second vertical wall 62 includes a second sealing means 62 dfor filling a gap with the third vertical wall 63. As shown in FIG. 3, the second sealing means 62 dis inclined forward and leftward.As illustrated in FIG. 4, the second vertical wall 62 is not connected to a vehicle body forming member such as the front side frame 3. The second vertical wall 62 is indirectly supported by the vehicle body forming member by being attached to the first vertical wall 61 and the third vertical wall 63. As illustrated in FIG. 1, fitting parts 62 gof the second vertical wall 62 to the first vertical wall 61 and the third vertical wall 63 are located at an upper end part of the second vertical wall 62.As illustrated in FIG. 4, a PCM (Power Train Control Module) 40 as an electrical component is attached to a left surface part of the second plate member 62 aof the second vertical wall 62. A bracket 41 is attached to the PCM 40 with bolts 101, and the PCM 40 is attached to the second vertical wall 62 through the bracket 41. The PCM 40 has a plurality of ribs 42 extending leftward and rightward. The ribs 42 serve to expand the exposed area of the PCM 40 to improve cooling efficiency of the PCM 40.In detail, as shown in FIG. 5, a plurality of (three in FIG. 5 ) protrusions 62 eprotrude leftward from the second plate member 62 a. An engaging part 62 ffor engaging an engaging hole 41 a(see FIG. 7 ) formed in the bracket 41 is provided at a tip end part of each protrusion 62 e. By these engaging parts 62f engaged with the respective engaging holes 41a of the bracket 41, the PCM 40 is mounted on the second vertical wall 62. Therefore, the second vertical wall 62 is an example of a specific vertical wall to which an electric component is attached to a side surface part (here, a left surface part) opposite to the motor.By providing the protrusions 62 eon the second plate member 62 a, the right ribs 42 can be enlarged in size as much as possible as illustrated in FIG. 4. In addition, a traveling wind, which is wind caused by the traveling vehicle, can more easily pass through the gaps between the right ribs 42. Therefore, the cooling efficiency of the PCM 40 can be improved.As illustrated in FIGS. 2 and 4, the PCM 40 is attached to the second vertical wall 62 so as to be located between the second vertical wall 62 and the peripheral wall 32 of the left suspension tower 30. In a state where the PCM 40 is disposed in the engine room ER, the PCM 40 is separated from the peripheral wall 32 of the left suspension tower 30. Therefore, the traveling wind can pass between the PCM 40 and the suspension tower 30 to efficiently cool the PCM 40.The PCM 40 has a connection port to be connected to a wire harness H at a front side. As illustrated in FIG. 6, the PCM 40 is inclined rearward and upward while being attached to the second vertical wall 62. Therefore, the communication port of the PCM 40 faces substantially upward. Therefore, as illustrated in FIG. 7, the wire harness H can be connected from above, and the convenience is improved.As illustrated in FIG. 5, a front hole part and a rear hole part into which bolts 101 are inserted are formed in an upper part of the bracket 41. As illustrated in FIG. 1, the bolt 101 is fastened to the upper part 31 of the left suspension tower 30 to be a coupling part 43 that couples the bracket 41 to the suspension tower 30. When viewed from the left side, while the front coupling part 43 is located in front of the second vertical wall 62, the rear coupling part 43 is located behind the center of the second vertical wall 62 in the front-rear direction. That is, the PCM 40 is also attached to and supported by the left suspension tower 30 through the bracket 41 in addition to the second vertical wall 62.By mounting and supporting the PCM 40 on the suspension tower 30 through the bracket 41, the second vertical wall 62 is indirectly supported by the suspension tower 30, which is the vehicle body constituting member, through the bracket 41. In addition, since the coupling part 43 of the PCM 40 and the suspension tower 30 are also provided rearward, the rear end part 62 cof the second vertical wall 62 is pulled leftward. Therefore, the second sealing means 62 dis pressed against the third vertical wall 63. As a result, the sealability of the second sealant 62 dis improved.In the third vertical wall 63, a heat insulating member is attached to the right surface of a third plate member 63a made of resin. The third plate member 63 aconceeds from the plate member constituting the rear wall part 52, and this heat insulating member is also the same as the heat insulating member of the rear wall part 52.The right side wall part 70 is divided into three vertical walls extending substantially in the up-down direction, similarly to the left side wall part 60. In detail, the right side wall part 70 includes a fourth vertical wall 71 located relatively foremost, a fifth vertical wall 72 disposed so as to oppose the right suspension tower 30, and the sixth vertical wall 73 extending substantially rearward from a rear end part of the fifth vertical wall 72 and preferably integrated with the rear wall part 52.In each of the fourth to sixth vertical walls 71- 73, a heat insulating member is attached to the left surface of the resin plate member. Although illustration is omitted, the fourth to sixth vertical walls 71- 73 are fastened to the right front side frame 3 with bolts.As illustrated in FIG. 8, a gap between the fifth vertical wall 72 and the right suspension tower 30 is narrower than the gap between the second vertical wall 62 and the left suspension tower 30.Next, a method of assembling the left side wall part 60 will be described. As illustrated in FIG. 9, in assembling the left side wall part 60, the third vertical wall 63 is first assembled with the vehicle body constituting member (e.g., the front side frame 3) together with the rear wall part 52.Next, the PCM 40 is mounted on the second vertical wall 62 to prepare a first sub-assembly 81 (a first process).Then, the air cleaner 20 is attached to the first vertical wall 61 to prepare a second sub-assembly 82.Next, the first sub-assembly 81 is arranged so that the PCM 40 is located on the opposite side of the engine in the vehicle width direction with respect to the second vertical wall 62, in detail so that the PCM 40 is located between the second vertical wall 62 and the left suspension tower 30 in the vehicle width direction (a second process). At this time, the second vertical wall 62 is attached to the third vertical wall 63 by the fitting part 62 g.Next, the bracket 41 of the PCM 40 is attached to the upper part 31 of the left suspension tower 30, so that the PCM 40 is attached to and supported by the suspension tower 30.Then, the second sub-assembly 82 is disposed in the engine room ER, and the first vertical wall 61 is attached to the vehicle body constituting member (e.g., the front side frame 3). At this time, the air duct 21 is also attached to the vehicle body constituting member.Then, the first vertical wall 61 is attached to the second vertical wall 62 by the fitting part 62 g.As described above, the left side wall part 60 of the capsule cover 50 is attached to the vehicle 1. Thus, by attaching and supporting the PCM 40 to the vehicle body constituting member together with the second vertical wall 62, after the PCM 40 is attached to the second vertical wall 62 in advance, the capability of mounting the PCM 40 can be improved.At this time, although the capsule cover 50 is provided for the purpose of heat insulation of the engine, the performance of the PCM 40 may be deteriorated by heat if the PCM 40 executing electronic control of the engine is also disposed inside the capsule cover 50.On the other hand, as in this embodiment, the PCM 40 may be disposed outside the capsule cover 50. According to this structure, an excessive rise in the temperature of the PCM 40 can be suppressed. Moreover, by disposing the PCM 40 outside the capsule cover 50, the PCM 40 can also be cooled appropriately.On the other hand, due to the current demands for downsizing the vehicle 1, the capsule cover 50 and the vehicle body constituting member (the suspension tower 30, etc.) tend to be considerably close to each other. Therefore, the ability to mount the PCM 40 is reduced by disposing the PCM 40 only outside the capsule cover 50.However, according to this embodiment, since the left side wall part 60 where the PCM 40 is disposed is composed of the plurality of vertical walls including the second vertical wall 62, the second vertical wall 62 may be disposed on the engine side after the PCM 40 is attached to the second vertical wall 62. Therefore, the PCM 40 can be easily disposed in the engine room ER in the state where the PCM 40 is mounted outside the capsule cover 50. Therefore, the capability of mounting the PCM 40 can be improved as much as possible.Moreover, in this embodiment, the second vertical wall 62 is disposed at the position opposing the left suspension tower 30 in the vehicle width direction with the gap S therebetween. The PCM 40 is attached to the second vertical wall 62 so as to be located between the second vertical wall 62 and the left suspension tower 30. Since the PCM 40 is disposed so as to be located between the second vertical wall 62 and the suspension tower 30, more traveling wind impinges on the PCM 40. As a result, the cooling efficiency of the PCM 40 can be improved.Moreover, in this embodiment, the electrical component such as the PCM 40 is not disposed between the fifth vertical wall 72 of the right side wall part 70 and the right suspension tower 30. Therefore, the vehicle width can be reduced as much as possible.Moreover, in this embodiment, the first vertical wall 61 is disposed in front of the second vertical wall 62, the third vertical wall 63 is disposed behind the second vertical wall 62, and the second vertical wall 62 is attached to the first and third vertical walls 61 and 63 without being attached to the vehicle body constituting member. The fitting parts 62 gfor the second vertical wall 62 to the first and third vertical walls 61 and 63 are located in the upper end part of the second vertical wall. Therefore, the removal of the second vertical wall 62 becomes easier. Therefore, the removal of the PCM 40 becomes easier as well. As a result, the capability of maintenance of the PCM 40 can also be improved.Moreover, in this embodiment, the PCM 40 is also attached to and supported by the left suspension tower 30, in addition to the second vertical wall 62. As a result, the PCM 40 can be held at the position where the traveling wind easily flows, and the cooling efficiency of the PCM 40 can be improved.Specifically, in this embodiment, one of the coupling parts 43 of the PCM 40 and the suspension tower 30 is located rearward of the center of the second vertical wall 62 in the front-rear direction. Therefore, the rear end portion 62 cof the second vertical wall 62 is pulled leftward. Therefore, the second sealing means 62 dis pressed against the third vertical wall 63. As a result, the sealability of the second sealant 62 dmay be improved.(Other Embodiments)The technology disclosed herein is not limited to the above embodiment and may be replaced without departing from the nature of the appended claims.For example, although in the above embodiment, the PCM 40 is also attached and fixed to the suspension tower 30 in addition to the second vertical wall 62, it may not be attached to the suspension tower 30.Moreover, although the PCM 40 for controlling the operation of the motor is illustrated as an electric component in the above embodiment, it is not limited to the PCM 40, and as long as it is an electric component that tends to obtain the effect by the heat, such as a semiconductor device, it may be the electric component in the technology of the present disclosure.The technology disclosed herein is useful for the engine compartment structure of the vehicle in which the electrical component is disposed in the engine compartment.DESCRIPTION OF REFERENCE NUMERALS1 Vehicle 30 Suspension tower (vehicle body forming member) 40 PCM (electrical component) 50 Capsule cover 51 Lid part 60 Left side wall part 61 First vertical wall (additional vertical wall) 62 Second vertical wall (specific vertical wall) 63 Third vertical wall (additional vertical wall) 81 First sub-assembly ER Engine room
