Description

The present invention relates to a heat insulator that protects an object, such as a vehicle battery, from ambient heat by enclosing it.

Conventionally, as this type of heat insulator, for example, a heat insulating cover disclosed in Patent Document 1 is known. Such a heat insulating cover has a rectangular tubular shape that matches the outer shape of the rectangular parallelepiped battery. The heat insulation cover is attached to the battery by covering the installed battery from above so as to surround the side surface of the battery.

JP 2015-183848 A

By the way, since the above-described heat insulating cover has a rectangular tubular shape that matches the outer shape of the battery, it is necessary to cover the battery from directly above in order to attach it to the battery. However, if the battery is installed in a narrow engine room, for example, it may not be possible to secure a sufficient space above the battery.

In such a case, the heat insulating cover interferes with other components positioned above the battery, making it difficult to attach the heat insulating cover to the battery. Therefore, there is still room for improvement in terms of increasing the degree of freedom in attaching the heat insulating cover to the battery.

Such problems are not limited to the heat insulating cover that encloses the battery, but are generally common to the heat insulating cover that encloses objects other than the battery that are mounted on the vehicle.

Means for solving the above problems and their effects will be described below.
A heat insulator that solves the above problems is a heat insulator that protects an object mounted on a vehicle from ambient heat, is mounted so as to surround the side of the object, and has openings at the upper and lower ends. A main body portion having a rectangular tubular shape with four side walls formed thereon, and each boundary between at least one of the four side walls and two side walls adjacent to the side wall has a lower end to an upper end. The specific side wall, which is the side wall positioned between the two cuts, has a cut extending toward the edge thereof, and the specific side wall has a movable portion that rotates using a portion sandwiched between the upper ends of the two cuts as a hinge. The gist is that it has

According to this configuration, the width of the opening at the lower end of the main body can be widened by rotating the movable portion outward. Therefore, the main body can be attached to the object not only from directly above but also obliquely from above. Therefore, it is possible to improve the degree of freedom in attaching the main body to the object.

In the above heat insulator, it is preferable that at least the specific side wall among the four side walls is provided with an elastomer having heat insulating properties.
According to this configuration, it is possible to further improve the heat insulation of the object to which the main body is attached.

In the above heat insulator, it is preferable that the elastomer provided on the specific side wall extends across the hinge portion.
According to this configuration, the elastomer is elastically deformed when the movable portion is rotated. Therefore, the elastic restoring force of the elastomer can be used when rotating the movable portion from the position after rotating to the original position before rotating. Therefore, it is possible to easily rotate the movable part from the position after rotating to the original position before rotating.

In the heat insulator described above, a fixing member is provided for fixing the object to which the main body is attached at a fixing position, and the fixing member holds the object to which the main body is attached to the fixing position. It is preferable to have a pressing portion that presses the movable portion from the outside when it is fixed.

According to this configuration, when the object to which the main body is attached is fixed at the fixed position by the fixing member, the outward rotation of the movable portion is suppressed by the pressing portion. Therefore, the fixing member can fix the object to which the main body is attached at the fixed position, and can suppress the outward rotation of the movable portion.

An embodiment in which a heat insulator is embodied in a battery insulator attached to a battery of a vehicle will be described below with reference to the drawings.
<Configuration of Battery Insulator 11>
As shown in FIG. 1, a battery insulator 11, which is an example of a heat insulator, protects a battery 12, which is an example of an object mounted on a vehicle, from ambient heat generated by, for example, an engine. The battery insulator 11 includes a body portion 13 mounted so as to surround the side surface of the battery 12, and a horizontal fixing plate 14 that holds the battery 12 with the body portion 13 mounted thereon at a predetermined fixed position in the engine room of the vehicle. and a fixing member 15 fixed thereon.

<Configuration of Battery 12>
As shown in FIG. 1, the battery 12 has a rectangular parallelepiped shape and is arranged on the fixed plate 14 in such a manner that the long side direction thereof coincides with the front-rear direction of the vehicle. A front projecting portion 12a projecting forward is formed on the lower end portion of the front surface of the battery 12 over the entire lateral direction (vehicle width direction), which is the short side direction. A rear protrusion 12b that protrudes rearward is formed on the lower end of the rear surface of the battery 12 over the entire left-right direction.

The upper surface of the front projecting portion 12a is inclined so that the height gradually decreases toward the front. The upper surface of the rear protruding portion 12b is inclined so that the height gradually decreases toward the rear. The rear protruding portion 12b of the battery 12 is engaged with an engaging portion 14a formed at the rear end portion of the fixing plate 14. As shown in FIG.

A pair of front and rear terminals 16 protrude from the upper surface of the battery 12 . A battery sensor 17 for detecting the voltage and current of the battery 12 is attached to the front terminal 16 of the pair of terminals 16 . The front end of the battery sensor 17 protrudes slightly forward from the front surface of the battery 12 . The height of the battery sensor 17 from the upper surface of the battery 12 is slightly higher than the protrusion height of the terminals 16 from the upper surface of the battery 12 .

<Configuration of Main Body 13>
As shown in FIGS. 1 and 2 , the main body 13 has a rectangular (square) tubular shape corresponding to the battery 12 . That is, the main body 13 has a rectangular tubular shape with four side walls 19 forming rectangular openings 18 at the upper and lower ends. The body portion 13 is made of, for example, a nonwoven fabric. The size of the opening 18 of the main body 13 is set to such an extent that the sides of the rectangular parallelepiped battery 12 can be enclosed.

The vertical length of the body portion 13 is set to be shorter than the vertical length of the battery 12 . Therefore, when the body portion 13 is attached to the battery 12 , the upper end portion and the lower end portion of the battery 12 are exposed from the body portion 13 . All of the four side walls 19 of the main body 13 are shaped like rectangular plates. The four side walls 19 of the main body 13 are a front wall 20, a rear wall 21, a right wall 22 and a left wall 23, respectively.

The front wall 20 and the rear wall 21 face each other in the front-rear direction. The right wall 22 and the left wall 23 face each other in the left-right direction. In the body portion 13 , cuts 24 extending from the lower end toward the upper end are formed at the boundaries between the front wall 20 and the right and left walls 22 and 23 adjacent to the front wall 20 . That is, cuts 24 are formed at two corner portions located on the front side of the body portion 13 and sandwiching the front wall 20 .

As shown in FIGS. 2 and 3 , the vertical length of the two cuts 24 is set to, for example, about 70% of the vertical length of the main body 13 . Therefore, the front wall 20 is configured to be rotatable so that the portion sandwiched between the upper ends of the two cuts 24 serves as a hinge portion 25 and opens outward (toward the front in this example). A portion of the front wall 20 below the hinge portion 25 is a movable portion 26 configured to be rotatable so as to open outward with the hinge portion 25 as the center of rotation. The movable part 26 functions as a door of the front wall 20 . In this example, the front wall 20 located between the two cuts 24 constitutes the particular side wall.

Rectangular plate-shaped elastomers 27 having heat insulation are provided on the outer surfaces of the four side walls 19 of the main body 13 so as to cover most of the outer surfaces. The elastomer 27 is attached to the outer surface of each side wall 19 by, for example, adhesive or double-sided adhesive tape. The elastomer 27 is made of, for example, soft urethane foam. An elastomer 27 provided on the outer surface of the front wall 20 extends across the hinge portion 25 of the front wall 20 .

<Structure of Fixing Member 15>
As shown in FIG. 1, the fixing member 15 is formed, for example, by bending a strip-shaped metal plate into a substantially L shape. The fixing member 15 has a fixing portion 15a, a first pressing portion 15b, and a second pressing portion 15c as an example of a pressing portion. In the fixing member 15, the first pressing portion 15b is positioned between the fixing portion 15a and the second pressing portion 15c.

A first insertion hole 15d through which the bolt 28 can be inserted is formed in the fixing portion 15a. When fixing the battery 12 to which the main body 13 is attached by the fixing member 15 on the fixing plate 14, the position corresponding to the first insertion hole 15d of the fixing portion 15a of the fixing member 15 on the fixing plate 14 is: A second insertion hole 14b through which the bolt 28 can be inserted is formed.

In the fixing portion 15a, the bolts 28 are arranged on the lower side of the fixing plate 14 in a state in which the bolts 28 are inserted through the first insertion holes 15d and the second insertion holes 14b from the upper side of the fixing portion 15a located on the fixing plate 14. It is fixed to the fixed plate 14 by screwing it into the nut 29 and tightening it. When the fixed portion 15a is fixed to the fixed plate 14, the first pressing portion 15b presses the upper surface of the front protruding portion 12a of the battery 12 from above, and the second pressing portion 15c presses the lower end portion of the movable portion 26 on the front wall 20. is pressed from the outside (front side) via an elastomer 27.

That is, when the battery 12 with the body portion 13 attached is fixed on the fixing plate 14 by the fixing member 15, the second pressing portion 15c moves the lower end portion of the movable portion 26 on the front wall 20 outward (front side). is pressed through the elastomer 27 from the

<Action of Battery Insulator 11>
Next, the operation of fixing the battery 12 on the fixing plate 14 by the battery insulator 11 will be described.

When fixing the battery 12 on the fixing plate 14 by the battery insulator 11 , first, the battery 12 is placed on the fixing plate 14 . Subsequently, the battery 12 is slid rearward on the fixing plate 14 so that the rear protruding portion 12b of the battery 12 is engaged with the engaging portion 14a of the fixing plate 14 . Subsequently, the battery 12 is covered with the body portion 13 from above. At this time, as shown in FIG. 4, another component 30 such as a cowl louver may be arranged directly above the rear portion of the battery 12 .

In such a case, when the body portion 13 is placed over the battery 12 from directly above, the rear portion of the body portion 13 collides with the other component 30 . Therefore, in this embodiment, the movable portion 26 of the front wall 20 of the main body portion 13 is rotated around the hinge portion 25 so as to open outward. Then, the opening 18 at the lower end of the main body 13 widens forward, and the elastomer 27 provided on the outer surface of the front wall 20 is elastically deformed so as to bend at the portion corresponding to the hinge 25 . As a result, the body portion 13 can be placed over the battery 12 from the front and obliquely upward so that the body portion 13 does not collide with the other component 30 .

As shown in FIG. 4 , when the body portion 13 is placed over the battery 12 from the front and obliquely upward, the inner surface of the movable portion 26 that opens outward with the body portion 13 tilted forward is placed on the front surface of the battery 12 . The battery 12 is covered with the body part 13 from the front obliquely upper side while being in contact with the battery 12. - 特許庁At this time, the front end of the battery sensor 17 protrudes slightly forward from the front surface of the battery 12 . However, by opening the movable portion 26 outward and tilting the body portion 13 forward, the inner surface of the movable portion 26 can be brought into contact with the front surface of the battery 12 so that the front wall 20 does not hit the battery sensor 17.

Subsequently, the body portion 13 is rotated so as to close the movable portion 26 with the hinge portion 25 as the center of rotation, and the body portion 13 is placed in a horizontal posture. At this time, since the elastic restoring force of the elastically deformed elastomer 27 covering the hinge portion 25 can be used to rotate the main body 13, the main body 13 can be easily placed in a horizontal posture. Then, as shown in FIG. 5, the body portion 13 is attached to the battery 12 so as to cover the side surface thereof. At this time, the lower end of the front wall 20 and the lower end of the rear wall 21 of the main body 13 contact the upper end of the upper surface of the front protruding portion 12a and the upper end of the rear protruding portion 12b of the battery 12, respectively.

Subsequently, as shown in FIG. 1, the fixing member 15 is arranged on the fixing plate 14 so that the first insertion hole 15d of the fixing member 15 overlaps the second insertion hole 14b of the fixing plate 14 . Subsequently, the bolt 28 is inserted into the first insertion hole 15d and the second insertion hole 14b from the upper side of the fixing member 15, and the bolt 28 is screwed into the nut 29 arranged on the lower side of the fixing plate 14 and tightened. As a result, the fixing portion 15 a of the fixing member 15 is fixed to the fixing plate 14 by the bolt 28 and the nut 29 .

In this state, the first pressing portion 15b of the fixing member 15 presses the upper surface of the front projecting portion 12a of the battery 12 from above, and the second pressing portion 15c of the fixing member 15 presses the lower end portion of the movable portion 26 of the front wall 20. It is pressed via the elastomer 27 from the outside (front side). Therefore, the fixing member 15 fixes the battery 12 on the fixing plate 14 at the front projecting portion 12a by the first pressing portion 15b, and rotates the movable portion 26 outward by the second pressing portion 15c. Suppress.

In this manner, the battery 12 is fixed on the fixing plate 14 by the battery insulator 11 . In this case, the fixed member 15 is dimensionally designed such that the second pressing portion 15 c interferes with the elastomer 27 on the outer surface of the movable portion 26 . Therefore, the portion of the elastomer 27 on the outer surface of the movable portion 26 that is pressed by the second pressing portion 15c is elastically deformed so as to be depressed. That is, the second pressing portion 15c is in a state of being embedded in the elastomer 27. As shown in FIG.

According to the embodiment detailed above, the following effects are exhibited.
(1) The battery insulator 11 is mounted so as to surround the side surface of the battery 12, and has a rectangular tubular main body 13 having four side walls 19 forming openings 18 at the upper and lower ends. . A cut 24 extending from the lower end to the upper end is formed at each boundary between the front wall 20 of the four side walls 19 and the left wall 23 and right wall 22 adjacent to the front wall 20 . The front wall 20 positioned between the two cuts 24 has a movable portion 26 that rotates with a portion sandwiched between the upper ends of the two cuts 24 as a hinge portion 25 .

According to this configuration, by rotating the movable portion 26 outward, the width of the opening portion 18 at the lower end of the main body portion 13 in the front-rear direction can be increased. Therefore, the body portion 13 can be mounted so as to cover the battery 12 not only from directly above but also from obliquely forward and upward. Therefore, it is possible to improve the degree of freedom in mounting the main body 13 to the battery 12 .

As a result, in the vehicle assembly process, the battery insulator 11 can be assembled to the battery 12 before or after the battery sensor 17 and the other component 30 are assembled. Incidentally, when the conventional heat insulating cover described in Patent Document 1 is used instead of the battery insulator 11, the heat insulating cover interferes with the battery sensor 17 and other parts 30 after assembly. Therefore, it is necessary to assemble the heat insulating cover to the battery 12 before assembling the battery sensor 17 and the other parts 30 . Therefore, using the battery insulator 11 of the present embodiment makes it possible to relax restrictions on the procedure compared to the case of using the conventional heat insulating cover described in Patent Document 1.

(3) In the battery insulator 11 , the elastomer 27 provided on the outer surface of the front wall 20 extends across the hinge portion 25 .
According to this configuration, when the movable portion 26 is rotated to open outward, the elastomer 27 is elastically deformed. Therefore, the elastic restoring force of the elastomer 27 can be used when the movable portion 26 is rotated from the position after being rotated so as to open to the original position before being rotated. Therefore, the movable portion 26 can be easily rotated from the position after being rotated to the original position before being rotated.

(4) The battery insulator 11 includes a fixing member 15 that fixes the battery 12 with the main body 13 mounted thereon to the fixing plate 14 . The fixing member 15 has a second pressing portion 15c that presses the movable portion 26 from the outside when the battery 12 with the body portion 13 attached is fixed on the fixing plate 14 .

According to this configuration, when the battery 12 with the main body 13 mounted thereon is fixed on the fixing plate 14 by the fixing member 15, the outward rotation of the movable portion 26 is suppressed by the second pressing portion 15c. be. Therefore, the fixing member 15 can fix the battery 12 with the body portion 13 mounted thereon on the fixing plate 14 and suppress the outward rotation of the movable portion 26 .
