Description

The present invention is a component comprising: a partition member that surrounds a weakly heat-resistant component to block radiant heat from a heat source; relating to the cover structure of

Japanese Patent Application Laid-Open No. 2002-200000 discloses a technique related to a cover structure for a component. The technique described in Patent Literature 1 is a structure that covers and supports a battery, which is a weakly heat-resistant component, in an engine room of a vehicle. As shown in FIG. 7, the battery 100 is accommodated and supported in a container-like battery tray 102 with an open top. Therefore, the battery 100 can be protected from the radiant heat of the engine positioned below the battery 100 . However, since the upper portion of the battery 100 is exposed from the battery tray 102, the air heated by the engine and rising may hit the exposed upper portion of the battery 100 and the temperature of the battery 100 may rise.

In order to solve the above problem, as shown in FIG. 8, the periphery of the battery 100 is surrounded by a partition 105, and the partition 105 is covered with a cover member 106 to block the upper opening 105h of the partition 105. can be considered. This eliminates the exposed portion of the battery 100 and protects the battery 100 from the heat of the engine.

JP 2012-126365 A

However, in the structure in which the partition wall 105 is covered with the lid member 106 from above, the gap between the partition wall 105 and the lid member 106 may be affected due to variations in the manufacturing accuracy of the partition wall 105 and the lid member 106 and deformation due to insufficient rigidity of the partition wall 105 . A gap opening at the bottom may be formed in the When the gap is formed between the partition wall 105 and the lid member 106, as shown in FIG. 8, the air (see the arrow) that is heated by the engine and rises may enter the partition wall 105 through the gap. This is not preferable from the viewpoint of protection of battery 100 .

The present invention has been made to solve the above problems, and the problem to be solved by the present invention is to make it difficult for the heat of the rising air heated by the heat source to be applied to the weakly heat-resistant parts. That is.

The above problems are solved by each invention. A first invention is a part cover structure comprising: a partition member that surrounds a weakly heat-resistant component to block radiant heat from a heat source; A flange-shaped protrusion projecting outward from the enclosure is formed at the upper end of the partition member, and the lid member covers the low heat-resistant component from above at the edge of the lid member. An edge portion is formed to overlap the protrusion of the partition wall member from above , and the outer wall surface of the partition member located on the heat source side has the protrusion portion above the heat source. A ridge extending along the protrusion is formed at the lower position.

According to the present invention, the upper end of the partition member is formed with a flange-like projection projecting outwardly of the enclosure. An edge portion of the lid member is formed with an edge overlapping the protrusion of the partition member from above in a state in which the lid member covers the weakly heat-resistant component from above. For this reason, the air that is heated by the heat source and rises rises along the outer wall surface of the partition member and is further guided outward from the enclosure along the projection formed on the upper end of the partition member. As a result, for example, even if a gap is formed between the protrusion of the partition member and the edge of the lid member, the air that is heated by the heat source and rises flows through the gap to the inside of the partition member (the inside of the enclosure). difficult to enter. Therefore, the heat of the air is less likely to be applied to the weakly heat-resistant component.
Also, the air rising along the outer wall surface of the partition member is guided in the direction away from the partition member by the ridges. For this reason, it becomes more difficult for the rising air to enter the inside of the partition member (the inside of the enclosure) through the gap. Moreover, since deformation of the partition member is suppressed by the protrusion, a gap is less likely to occur between the protrusion of the partition member and the edge of the lid member.

According to the second aspect of the invention, the projection of the partition member protrudes obliquely upward from the upper end of the partition member. As a result, the rising air is efficiently guided to the outside of the enclosure by the protrusion of the partition member, and is less likely to enter the gap between the protrusion of the partition member and the edge of the lid member.

According to the third invention , the lid member covers the weakly heat-resistant component from above, and in a state in which the edge of the lid member overlaps the protrusion of the partition member, the protrusion of the partition member overlaps the edge of the lid member. It protrudes outward from the part. That is, the protrusion of the partition member protrudes outward with respect to the gap between the protrusion of the partition member and the edge of the lid member. As a result, the air guided outward from the enclosure along the projection of the partition member is more difficult to enter into the gap.

According to the present invention, the heat of the rising air heated by the heat source is less likely to be applied to the weakly heat-resistant component.

The battery cover mechanism 40 is provided on the front side of the cowl louver 15 as shown in FIG. 2, and the relay box 35 is provided on the front side of the battery cover mechanism 40 .

<About the battery cover mechanism 40>
The battery cover mechanism 40 is a mechanism that protects the battery 30, which is a weakly heat-resistant component, from the heat of the engine E. As shown in FIG. As shown in FIGS. 2 and 3, the battery cover mechanism 40 includes a partition member 43 that covers the battery 30 and the battery tray 32 from the left side, that is, the engine E side, and a lid member 45 that covers the battery 30 from above. I have. As shown in FIG. 2, the lid member 45 is configured to block the space surrounded by the partition member 43, the relay box 35, the cowl louver 15, and the like from above. Here, the relay box 35 is a box that houses the relays that make up the electric circuit of the vehicle 10, but also functions as a partition member that covers the battery 30 and the battery tray 32 from the front side.

<About the partition member 43>
The partition member 43 that constitutes the battery cover mechanism 40 is a heat-resistant member that blocks radiant heat from the engine E, and is made of, for example, a sound absorbing material. As shown in FIG. 2 and the like, the partition member 43 is formed in the shape of a wall elongated in the front-rear direction so as to enclose the battery 30 and the battery tray 32 on the suspension tower 22 from the left side. A front connecting mechanism 432 for connecting the partition member 43 to the rear left corner of the relay box 35 is provided at the front edge of the partition member 43 . A rear connecting mechanism 433 for connecting the partition member 43 to the front wall portion of the cowl louver 15 is provided at the rear end edge of the partition member 43 .

As shown in FIGS. 3 to 5 and the like, the upper end of the partition member 43 is formed with a flange-like protrusion 435 that protrudes outward from the enclosure. As shown in FIG. 4, the flange-shaped protrusion 435 is formed with a substantially constant width from the front to the rear of the partition member 43 . Moreover, as shown in FIG. 5, the projecting portion 435 protrudes from the upper end of the partition member 43 in an obliquely upwardly inclined state. Furthermore, as shown in FIGS. 4 and 5 , on the outer wall surface of the partition member 43 , a projecting ridge 437 extending in the front-rear direction along the flange-shaped projection 435 is formed in a bead shape under the projection 435 . formed. Forming the ribs 437 extending in the front-rear direction on the partition member 43 in this manner improves the strength of the partition member 43 and suppresses deformation of the partition member 43 .

<Regarding the lid member 45>
The lid member 45 that constitutes the battery cover mechanism 40 is injection molded of resin, and as shown in FIGS. It is shaped like a shallow hat. A front connecting mechanism (not shown) for connecting the lid member 45 to the rear edge of the relay box 35 is provided at the front end of the inclined wall portion 453 of the lid member 45 . A rear connecting mechanism 456 for connecting the lid member 45 to the front wall of the cowl louver 15 is provided at the rear end of the ceiling portion 451 of the lid member 45, as shown in FIG. Furthermore, as shown in FIGS. 4 and 5, a flange-like edge portion 453f is formed on the left end edge of the inclined wall portion 453 of the lid member 45 so as to overlap the protrusion 435 of the partition member 43 from above. ing.

That is, the edge portion 453f of the lid member 45 protrudes obliquely upward from the left end edge of the inclined wall portion 453 of the lid member 45 at an inclination angle equal to that of the protrusion 435 of the partition member 43 . Further, the width dimension of the edge portion 453f of the lid member 45 is set smaller than the width dimension of the protrusion 435 of the partition member 43, as shown in FIGS. For this reason, the lid member 45 covers the battery 30 from above, and in a state where the edge 453f of the lid member 45 overlaps the protrusion 435 of the partition member 43 from above, the protrusion 435 of the partition member 43 covers the lid. It protrudes outside the edge 453 f of the member 45 .

<Working of Battery Cover Mechanism 40>
As described above, the edge 453f of the lid member 45 and the protrusion 435 of the partition member 43 project obliquely upward at the same inclination angle as shown in FIG. It overlaps with the protrusion 435 of the partition member 43 from above. Furthermore, the projection 435 of the partition member 43 protrudes outside the edge 453 f of the lid member 45 . A ridge 437 extending in the front-rear direction is formed on the outer wall surface of the partition member 43 . Therefore, as shown in FIG. 6 , the air that is heated by the engine E in the engine room ER and rises first contacts the ridge 437 while rising along the outer wall surface of the partition member 43 . Then, part of the rising air rises while moving away from the partition member 43 . Further, the air rising along the outer wall surface of the partition member 43 after passing through the projection 437 contacts the lower surface of the protrusion 435 of the partition member 43 and moves along the protrusion 435 in the direction away from the partition member 43. while rising. Therefore, for example, even if a gap S is formed between the edge portion 453f of the lid member 45 and the projection 435 of the partition member 43, the air heated by the engine E passes through the gap S to the inside of the partition member 43. will no longer enter.

<Correspondence between terms used in the present embodiment and terms related to the present invention>
The battery 30 in this embodiment corresponds to the weakly heat-resistant component in the present invention. Also, the engine E corresponds to the heat source in the present invention. Furthermore, the partition member 43 and the relay box 35 in this embodiment correspond to the partition member in the present invention.

<Advantages of the battery cover mechanism 40 according to the present embodiment>
According to the battery cover mechanism 40 according to the present embodiment, the upper end of the partition member 43 is formed with a flange-like protrusion 435 that protrudes outward from the enclosure. Further, at the edge of the lid member 45, an edge portion 453f is superimposed on the protrusion 435 of the partition member 43 from above while the lid member 45 covers the battery 30 (weakly heat-resistant component) from above. formed. Therefore, the air heated by the engine E (heat source) rises along the outer wall surface of the partition member 43, and further along the protrusion 435 formed at the upper end of the partition member 43, flows outward from the enclosure. be guided. As a result, for example, even if a gap S is formed between the protrusion 435 of the partition member 43 and the edge portion 453f of the lid member 45, the air that is heated and rises will escape from the gap S to the inside (enclosure) of the partition member 43. inside) becomes difficult to enter. Therefore, the heat of the air is less likely to be applied to the battery 30 . Also, the air rising along the outer wall surface of the partition member 43 is guided away from the partition member 43 by the protrusion 437 of the partition member 43 . In addition, since deformation of the partition member 43 is suppressed by the protrusion 437 , the gap S is less likely to occur between the protrusion 435 of the partition member 43 and the edge portion 453 f of the lid member 45 .

<Change example>
Here, the present invention is not limited to the above embodiments, and modifications can be made without departing from the gist of the present invention. For example, in the present embodiment, regarding the battery cover mechanism 40 arranged on the rear side of the relay box 35 , the partition member 43 is formed in the shape of a long fence in the front-rear direction on the left side of the battery 30 . However, in the case of a vehicle in which the relay box 35 is located at a different position, the partition member 43 of the battery cover mechanism 40 is formed into a generally L-shaped wall so that the front side and the left side of the battery 30 can be enclosed by the partition member 43 . is also possible. Further, in the present embodiment, the edge portion 453f of the lid member 45 and the protrusion 435 of the partition member 43 project obliquely upward. However, a configuration in which the edge portion 453f of the lid member 45 and the protrusion 435 of the partition member 43 protrude substantially horizontally is also possible. Further, in this embodiment, an example in which the flange-shaped edge portion 453f is formed on the left end edge of the inclined wall portion 453 of the lid member 45 is shown. However, it is also possible to omit the flange-shaped edge portion 453f and make the end edge of the inclined wall portion 453 of the lid member 45 an edge portion overlapping the protrusion 435 of the partition member 43 from above. Furthermore, although the battery 30 has been exemplified as the weakly heat-resistant component, the present invention can also be applied to, for example, a cover structure that covers a brake booster as the weakly heat-resistant component. Moreover, in the present embodiment, the engine E is used as an example of the heat source, but the present invention can also be applied to a vehicle equipped with a motor or the like instead of the engine E.
