[Mounting method of lid member]
As shown in FIGS. 2 to 4, the lid member 45 is arranged so as to cover the upper side of the component 30 and attached in the engine room ER. When attaching the lid member 45, as shown in FIG. 7, the lid member 45 is inclined rearward and downward of the vehicle so that the fitting portions 50 and the like provided at the rear end portion E1 are directed downward. . Subsequently, the fitting portions 50 and the like of the lid member 45 are inserted between the upper edge portion 601 and the lower edge portion 602 of the respective fitted portions 60 of the cowl louver 15 while being moved rearward and downward of the vehicle. (See arrow A1 in FIG. 7). At this time, the upper surfaces of the fitting portions 50 and the like are moved along the upper protrusions 61 and 61X of the fitted portions 60 and the like, so that the fitting portions are smoothly inserted between the upper edge portion 601 and the lower edge portion 602. be able to. Then, while the fitting portions 50 and the like are inserted into the fitted portions 60 and the like, the front side of the lid member 45 is lowered (see arrow A2 in FIG. 7). As described above, in this embodiment, the lid member 45 is tilted to insert the fitting portions 50 and the like into the mated portions 60 and the like, and then the front side of the lid member 45 is lowered downward. The rear end E1 of the member 45 is smoothly attached to the engine room ER. Therefore, according to the above-described configuration, it is possible to improve the assembling workability of the lid member 45, shorten the work tact time, and reduce assembling defects. As shown in FIG. 6, the fitting portions 50 and the like of the lid member 45 are fitted to the fitted portions 60 and the like from the rearward direction of the vehicle, which is the fitting direction. The vehicle rearward direction, which is the fitting direction of the fitting portions 50 and the like, is a direction that intersects the vehicle height direction (vertical direction in FIG. 6 ), which is the bending deformation direction of the lid member 45 . When the engine room ER is closed with the engine hood 16 as shown in FIG. 4, the rear end of the engine hood 16 is supported by the cowl louver 15 so that the upper side of the lid member 45 can be covered. .

Here, the fitting state of the fitting portions 50 and 50X shown in FIG. 5 will be described by taking the fitting portion 50 on the left side as an example. 5 and 6, the left fitting portion 50 has a lower edge portion 602 of the left fitting portion 60 via lower protrusions 51 and 51X provided on its lower surface (one side). (the other) is partially in contact, that is, in the left-right direction, only the protrusions 51 and 51X are in contact. Upper projections 61 and 61X provided on the upper edge portion 601 (another side) of the left fitting portion 60 are partially in contact with the upper surface (another side) of the left fitting portion 50. ing. In this way, the left fitting portion 50 and the fitted portion 60 are partially in contact with each other through the protrusions (51, 61, etc.). , vertical gaps are less likely to occur. Therefore, even if the lid member 45 is subjected to vibrations during vehicle travel, the fitting portion 50 on the left side of the lid member 45 is less likely to rattle in the vertical direction. .

Also, in this embodiment, as shown in FIG. can engage. At this time, referring to FIG. 4, after the engaging claws 72 of the engaging portions 70 and the like are bent downward and inserted into the rear openings 821 of the engaged portions 80 and the like, the engaging claws 72 are returned to their original positions. The tip is projected from the top opening 822 while returning to the top. By engaging the engaging portions 70 and the like provided at the front end portion E2 of the lid member 45 with the engaged portions 80 and the like, the front end portion E2 of the lid member 45 can be attached to the engine room ER. Since the front end E2 of the lid member 45 is engaged with the engine room ER, the fitting portions 50 and the like are not unintentionally pulled out from the fitting portions 60 and the like in the lid member 45 in a free state without bending deformation. It becomes difficult to come off. Further, the engaging portions 70 and the like engage with the engaging portions 80 and the like so that the engaging claws 72 can rotate vertically. For this reason, when inspecting the component 30, the component 30 can be removed from the lid member 45 by rotating the lid member 45 upward about the engaging portions such as the engaging portions 70 and the engaged portions 80. It becomes exposed to the outside. When the cover member 45 is rotated, the fitting portions 50 and the like can be manually removed from the fitted portions 60 and the like.

[Behavior of lid member when absorbing impact]
In the vehicle 10 shown in FIG. 4, the impact load applied to the front portion of the vehicle 10 is absorbed by the engine hood 16 deforming together with the cowl louver 15 into the engine room ER (lower side in FIG. 4). In this type of configuration, it is desired that the cover member 45 is mounted inside the engine room ER while ensuring the deformation stroke SK of the engine hood 16, that is, the absorbability of the impact load. Therefore, in the component cover structure of the present embodiment, referring to FIGS. The lid member 45 is attached in the engine room ER by being fitted to 60 (60X). Each fitting portion 50 (50X) is fitted to each fitting portion 60 (60X) from the fitting direction (vehicle rearward direction in each figure) intersecting with the direction in which the lid member 45 bends and deforms. In addition, the lid member 45 is configured to move in the direction opposite to the fitting direction by flexural deformation.

According to the above configuration, the engine hood 16 is deformed during impact absorption, and presses the lid member 45 downward as shown in FIG. 4 (see the broken line state in FIG. 4). 4 and 8, the lid member 45 to which the external force F (load) is applied from the engine hood 16 is flexurally deformed downward in the vehicle height direction while pulling the rear end E1 toward the front side of the vehicle. do. As the rear end portion E1 of the lid member 45 is pulled toward the front side of the vehicle in this way, the fitting portion 50 and the like provided at the rear end portion E1 move in the vehicle front direction opposite to the fitting direction. As a result, it comes to be separated from each fitted portion 60 and the like (see arrow A3 in FIG. 8). The fitting portions 50 and the like and the to-be-fitted portions 60 and the like are partially in contact with each other through the lower protrusions 51 and 51X and the upper protrusions 61 and 61X. For this reason, the fitting portions 50 and the like receive less friction from the fitting portions 60 and the like during forward movement, and are easily disengaged from the fitting portions 60 and the like. Then, as shown in FIG. 4, the lid member 45 is removed (the state indicated by the two-dot dashed line in FIG. 4). It becomes possible to secure the deformation stroke SK to the lower side of . Further, in the cover structure of the parts, it is not necessary to make the installation height of the engine hood 16 higher than necessary in order to secure the deformation stroke SK.

As described above, in the component cover structure of the present embodiment, when the vehicle portion surrounding the engine room ER is deformed, the lid member 45 is bent and deformed to the external force applied from the vehicle portion. Then, the lid member 45 is flexurally deformed and the fitting portions 50 and 50X move in the direction opposite to the fitting direction, whereby the fitting portions 50 and 50X are disengaged from the fitted portions 60 and 60X. become. That is, when the engine hood 16 as a vehicle portion deforms into the engine room ER together with the cowl louver 15 to absorb the impact, the lid member 45 to which the external force is applied from the vehicle portion bends and deforms in the vehicle height direction. , the fitting portions 50 and 50X are separated from the fitting portions 60 and 60X. Therefore, when the vehicle portion is deformed into the engine room ER to absorb the impact, the deformation stroke SK of the vehicle portion can be secured by removing the lid member 45 . Therefore, according to this embodiment, the cover member 45 can be mounted in the engine room ER while ensuring the ability to absorb the impact load of the vehicle 10 .

Further, the fitting portions 50, 50X and the fitted portions 60, 60X of the present embodiment are partially in contact with each other via respective protrusions (51, 61, etc.), and the protrusions interpose therebetween. Therefore, it is difficult to create a gap in the bending deformation direction of the lid member 45 (for example, the vehicle height direction). For this reason, the fitting portions 50 and 50X are easily moved in the direction opposite to the fitting direction, but are difficult to move in the bending deformation direction with respect to the fitted portions 60 and 60X. In this embodiment, since the engaging portion 70 provided on the cover member 45 is engaged with the engaged portion 80, the engaged portions 60, 60, 60, 60, 60, 60, 60, 60, 60, 60, 60, 60, 60, 60, 60 Unintended disengagement of the fitting portions 50, 50X with respect to 60X is less likely to occur.

The cover structure of the component of this embodiment is not limited to the embodiment described above, and can take various other embodiments. Although the configuration of the lid member has been exemplified in the present embodiment, it is not intended to limit the configuration of the lid member. This lid member can be provided with a plurality of or a single fitting portion at an appropriate position. The fitting portion can be fitted to the fitted portion in a direction that intersects the bending deformation direction. can be exemplified. For example, the fitting portion provided on the front side of the lid member can be fitted to the fitted portion provided on the member (relay box, etc.) on the front side of the engine room from the front direction of the vehicle. Further, the fitting portion provided on the outside in the vehicle width direction of the lid member can be fitted to the fitted portion of the engine room from the vehicle width direction. For example, the fitting portion provided on the right side of the lid member can be fitted to the fitted portion provided on the upper member or the like on the right side of the engine room from the right direction. In this case, the vehicle width direction (rightward direction) is the fitting direction, and the fitting portion moves in the direction opposite to the fitting direction (leftward direction) so that it is disengaged from the fitted portion. Further, the engaging portion can be provided at an appropriate position of the lid member according to the position of the fitting portion, or can be omitted. When the engaging portion is omitted, the other end of the lid member may be fixed to the engine room, and a pair of fitting portions provided at one end and the other end of the lid member may be installed in the engine room. It can also be fitted to the corresponding fitted portion provided. The fitting portion and the fitted portion may be fitted through a projection provided on either of them, or may be fitted without the projection. The position and the number of protrusions can be changed as appropriate, and the protrusions do not necessarily have to be formed in the shape of vertical walls (linearly) extending in the front-rear direction, and can be formed in points. For example, it is possible to form notches or holes linearly or pointwise in the fitting portion or the fitted portion so as to make partial contact.

Further, in the present embodiment, an example has been described in which the lid member is flexurally deformed in the vehicle height direction when an external force is applied. Alternatively, the lid member may be oriented in the vehicle width direction or the vehicle front-rear direction so that the cover member is flexurally deformed in the vehicle width direction or the vehicle front-rear direction when an external force is applied. For example, when the upper member deforms in the vehicle width direction to absorb the load, the lid member may be deformed in the vehicle width direction by receiving an external force from the upper member to disengage the fitting portion. A plurality of lid members or a single lid member can be provided at appropriate positions in the engine room. Also, the parts in the engine room can be assumed to include various parts in addition to the battery and brake-related parts. The configuration of this embodiment can also be applied to a vehicle equipped with a motor or the like that replaces the engine, and the engine room does not necessarily need to be provided in the front part of the vehicle.
