[0005] Patent Document 1: Japanese Patent Application Publication No. 2001-25135 Summary of the invention

[0006] Technical problem that the invention aims to solve

[0007] In the above-mentioned storage body, the water-stopping function inside and outside the storage body may not be ensured. For example, when the gasket provided on the cover body is manufactured by resin molding, a resin injection mark is formed on a part of the gasket. The resin molding mark is a mark formed by cutting off the gate during resin molding, which becomes a concave-convex surface on the gasket. Therefore, if the resin injection mark is formed on the gasket, a gap may be generated between the gasket and the shell, etc., and sometimes the water-stopping function between the shell and the cover body cannot be fully ensured.

[0008] Therefore, an object of the present invention is to provide a storage box capable of ensuring the water stopping function of a packing member.

[0009] Technical solutions to the problem

[0010] That is, the storage box involved in the present invention comprises: a main body, which can store electronic components inside and has an opening that connects the inside and the outside; a cover, which is installed on the main body and is configured to be loaded and unloaded relative to the opening; and a resin-made cushioning member, which is provided on the cover and is at least configured in the water-stopping area between the main body and the cover to perform water-stopping between the main body and the cover, and the cushioning member has a resin injection portion, which is connected to the water-stopping area and is formed in a non-water-stopping area deviating from the water-stopping area, and becomes a resin injection position during resin molding.

[0021] Hereinafter, the embodiments of the present invention will be described in detail based on the accompanying drawings. In addition, the present invention is not limited to the embodiments. In addition, the constituent elements of the following embodiments include elements that can be easily replaced by those skilled in the art, or substantially the same elements.

[0022] [Implementation Method]

[0023] A storage box according to a first embodiment of the present invention will be described.

[0024] Figure 1 is an exploded perspective view of the storage box involved in the first embodiment, Figure 2 1 is an explanatory diagram of a cushion member of a storage box according to a first embodiment. Figure 3 yes Figure 2 A cross-sectional view of the storage box at III-III.

[0025] like Figure 1As shown, the storage box 1 involved in the present embodiment is a box for storing electronic components, and is installed in a vehicle, for example, as an electrical junction box for storing electronic components including fuses and relays. The storage box 1 includes a main body 2, a cover 3, and a cushioning member 4. The main body 2 can store electronic components inside, and has an opening 21 that connects the inside and the outside. The main body 2 is, for example, a box-shaped body with a bottom and a top open, and functions as a side cover. In this case, for example, the bottom of the main body 2 is closed by installing a lower cover 5. The top of the main body 2 is an opening 21 that connects the inside and the outside, and is closed by providing the cover 3. The opening 21 is, for example, an opening formed by opening the entire upper surface of the main body 2. In addition, in Figure 1 In the embodiment, the main body 2 is configured to cover the side portion of the storage box 1 all around, but it can also be configured to cover the side portion of the storage box 1 in combination with other components. For example, the main body 2 can also be formed in a shape in which a part of the side portion of the storage box 1 is cut away, and other components are installed on the cut away portion to cover the side portion of the storage box 1.

[0026] The cover 3 is an upper cover that covers the opening 21 of the main body 2, is installed on the main body 2 to cover the opening 21, and is set to be removable relative to the opening 21. The cover 3 has a top face 31 and a lower wall 32. The top face 31 is the upper surface part of the cover 3, and is formed in a shape consistent with the shape when the main body 2 is observed from above, for example, in a rectangular or substantially rectangular shape. The lower wall 32 is a wall portion extending downward from the outer edge of the top face 31, and is formed over the entire outer edge of the top face 31. The downward extension length of the lower wall 32 is set according to the shape of the upper edge 22 of the main body 2. That is, the upper edge 22 of the main body 2 changes up and down along the outer edge according to the conditions such as the installation space and the outer shape of the storage box 1. The downward extension length of the lower wall 32 is set so that the lower wall 32 can be joined to the upper edge 22 over the entire circumference. The cover 3 is provided with a snap-fitting portion 33. The engaging portion 33 is a portion that engages with the engaged portion 23 of the main body 2 to hold and release the cover 3 with respect to the main body 2. The engaging portion 33 is formed on the outer surface of the lower wall 32, for example, and is provided in plurality.

[0027] The cushion component 4 is a water-stopping component that stops water between the main body 2 and the cover 3, and is formed of resin. The cushion component 4 is formed of a resin having lower rigidity than the cover 3, for example, an elastic resin such as an elastomer. The cushion component 4 has a main body 41 and a resin injection portion 42. The main body 41 is a portion that functions as a water-stopping component, and is arranged in a water-stopping area S between the main body 2 and the cover 3, and is formed in a ring shape. The water-stopping area S is an area between the main body 2 and the cover 3, and is an area that abuts against the main body 2 on one side and against the cover 3 on the other side. The resin injection portion 42 is a portion that becomes the resin injection position when the cushion component 4 is resin-molded, and is connected to the main body 41 and is formed in a non-water-stopping area N that deviates from the water-stopping area S. For example, as Figure 2 As shown, the main body 41 is arranged along the water stop area S of the outer edge of the cover part 3. And the resin injection part 42 is branched from the main body 41 and is formed protrudingly. For example, the resin injection part 42 is formed to extend from the water stop area S where the main body 41 is arranged to the inner side of the cover part 3. That is, the resin injection part 42 is formed to branch from the main body 41 and extend to the center side of the cover part 3, and is formed in the non-water stop area N that is not sandwiched between the main body 2 and the cover part 3. Therefore, even if there are gate marks on the resin injection part 42 and there are bumps on the surface of the resin injection part 42, it will not affect the water stop performance based on the cushion part 4. Therefore, the water stop performance of the cushion part 4 can be reliably ensured. In addition, Figure 2 This is a diagram viewed from the back side (lower side) of the cover portion 3, and illustration of the main body portion 2 is omitted.

[0028] like Figure 3 As shown, the cushion member 4 is disposed in a groove 322 formed in the cover portion 3. The groove 322 is formed between an outer wall 323 and an inner wall 324 disposed below the hanging portion 321. The hanging portion 321 is a part of the lower wall portion 32, and is a wall portion extending downward from the top surface portion 31. The inner wall 324 is a wall portion connected to the lower portion of the hanging portion 321. The outer wall 323 is a wall portion connected to the lower portion of the hanging portion 321 via the protrusion 225, and is located on the outer side of the inner wall 324 and is disposed at a predetermined distance from the inner wall 324. The protrusion 325 is disposed to protrude outward from the lower end of the hanging portion 321, and the front end is connected to the outer wall 323. In addition, an extension portion 326 is formed in a continuous manner below the outer wall 323. The extension portion 326 is a wall portion that covers the outer side of the side wall 24 of the main body 2. The groove 322 is formed by the inner wall 324, the protrusion 325 and the outer wall 323, and is a space open at the bottom. The groove 322 extends along the extension direction of the lower edge of the lower wall 32 (in Figure 3The liner member 4 is, for example, arranged at a position on the inner side of the upper portion of the groove 322 so as to contact the protrusion 325. When the cover portion 3 is mounted on the main body 2, the upper edge portion 22 of the main body 2 is inserted into the groove 332. For example, the upper edge portion 22 is formed with two protrusions 221 and 222 protruding upward from the upper end, and one of the protrusions 221 is inserted into the groove 332. The protrusions 221 and 222 are arranged along the extension direction of the upper edge portion 22 (in the Figure 3 The protrusions formed therein (in the Y direction) are formed parallel to the inside and outside and are arranged so as to be located on the outside and inside of the inner wall 324.

[0029] Next, a method for manufacturing the storage box according to the first embodiment will be described.

[0030] Figure 4 , Figure 5 and Figure 6 It is an explanatory diagram of the manufacturing method of the storage box which concerns on 1st Embodiment, and is an explanatory diagram of the resin molding of a cover part and a cushion member.

[0031] The storage box 1 is manufactured by attaching a cover 3 provided with a cushion member 4 to a main body 2. The main body 2, the cover 3, and the cushion member 4 are manufactured separately. The main body 2 is manufactured, for example, by resin molding. In addition, when the main body 2 is not made of resin, it can also be manufactured by a method other than resin molding.

[0032] The cover 3 and the cushion member 4 are manufactured by resin molding. For example, the cover 3 and the cushion member 4 are manufactured by two-color molding using two different resins. Specifically, first, Figure 4 As shown, a first resin 110 for molding having fluidity at high temperature is injected into a molding space 103 formed between molds 101 and 102. The molding space 103 is formed corresponding to the shape of the cover 3. Then, the first resin 110 is filled in the molding space 103, and solidified by cooling to form the cover 3.

[0033] Then, if Figure 5As shown, a second resin 111 for molding that has fluidity at high temperature is injected into the molding space 105 formed between the mold 101 and the cover portion 3. The molding space 105 is formed corresponding to the shape of the cushion component 4. At this time, the second resin 111 is injected into the molding space 105 from a position that becomes the resin injection portion 42. That is, the gate 104A of the mold 104 is set at a position that becomes the resin injection portion 42. The second resin 111 is a resin different from the first resin 110, and becomes a resin with lower rigidity than the first resin 110 when it is cured. Then, the second resin 111 is injected into the molding space 105 through the gate 104A and fills the molding space 105. Then, the second resin 111 is cooled and cured, and the second resin 111 becomes the cushion component 4.

[0034] And, if Figure 6 As shown, the cover portion 3 and the cushion component 4 are manufactured by two-color molding. At this time, a gate mark 42A is formed on the surface of the resin injection portion 42 of the cushion component 4. The gate mark 42A is a convex portion or a concave portion formed by cutting the resin of the gate 104A, and sometimes becomes a burr, a depression, a crack or a gap. However, since the resin injection portion 42 is located at a position deviated from the water-stopping area S between the main body 2 and the cover portion 3, even if the gate mark 42A is formed in the resin injection portion 42, it will not affect the water-stopping performance of the cushion component 4. Therefore, it is possible to ensure high water-stopping performance based on the cushion component 4 and achieve an improvement in the water-stopping performance based on the cushion component 4.

[0035] As described above, according to the storage box 1 involved in this embodiment, the cushion member 4 that performs water stopping of the main body 2 and the cover 3 has the resin injection portion 42 in the non-water stopping area N deviated from the water stopping area S. Therefore, the resin injection portion 42 is not formed in the water stopping area S, and the surface of the water stopping area S is not uneven due to the resin injection. Therefore, the storage box 1 can reliably ensure the water stopping function based on the cushion member 4.

[0036] In the storage box 1 according to the present embodiment, the resin injection portion 42 is formed to extend from the water stop region S toward the inside of the cover portion 3. Therefore, no unevenness due to the resin injection is generated on the surface of the water stop region S. Therefore, the storage box 1 can reliably ensure the water stop function based on the cushion member 4.

[0037] Next, a storage box according to a second embodiment will be described.

[0038] Figure 7 is an exploded perspective view of a storage box according to a second embodiment. Figure 8 yes Figure 7 A cross-sectional view of the storage box at VIII-VIII.

[0039] The storage box 1A according to the second embodiment is substantially similar to the storage box 1 according to the first embodiment, except that the structure of the resin injection portion 42 of the cushion member 4 is different. That is, in the cushion member 4 of the storage box 1 according to the first embodiment, the resin injection portion 42 extends from the water stop region S to the inside of the cover portion 3, but the cushion member 4 of the storage box 1A according to the second embodiment is different in that the resin injection portion 42 extends from the water stop region S to the outside of the cover portion 3.

[0040] like Figure 8 As shown, the resin injection portion 42 is formed to extend from the water-stopping area S where the main body 41 is arranged to the outside of the cover portion 3. That is, the resin injection portion 42 is formed to branch from the main body 41 and extend to the outside of the cover portion 3, and is formed to penetrate the cover portion 3 and be exposed on the outer surface of the cover portion 3. By forming the resin injection portion 42 in this way, the resin injection portion 42 is formed in the non-water-stopping area N that is not sandwiched between the main body 2 and the cover portion 3. Therefore, even if there are gate marks in the resin injection portion 42 and the surface of the resin injection portion 42 is uneven, it will not affect the water-stopping performance of the cushioning member 4. Therefore, the storage box 1A can reliably ensure the water-stopping performance of the cushioning member 4.

[0041] The cover 3 and cushion member 4 of the storage box 1A are manufactured by two-color molding, for example, similarly to the storage box 1 according to the first embodiment. In this case, during the molding of the cushion member 4, the second resin 111 is injected from a position exposed on the outer surface of the cover 3. Therefore, even if the surface of the resin injection portion 42 is formed with concave and convex portions of the gate marks, since it is not the water-stopping area S between the main body 2 and the cover 3, it does not affect the water-stopping function of the cushion member 4.

[0042] Thus, in the storage box 1A involved in the present embodiment, the resin injection portion 42 is formed by extending from the water stop area S to the outside of the cover portion 3. Therefore, no unevenness due to the resin injection is generated on the surface of the water stop area S. Therefore, the storage box 1A can reliably ensure the water stop function based on the cushion member 4. In addition, in the storage box 1A, since the resin injection portion 42 penetrates the inside and outside of the cover portion 3, it is possible to make it difficult for the cushion member 4 to deviate from the water stop area S. Therefore, the storage box 1A can reliably ensure the water stop function based on the cushion member 4.

[0043] It should be noted that the storage box according to the embodiment of the present invention is not limited to the above embodiment, and various modifications can be made within the scope of the claims. In addition, the storage box of this embodiment can also be constructed by appropriately combining the constituent elements of the above-described embodiment and modified example.

[0044] For example, in the above-described embodiment, the case where the storage box is applied to an electrical junction box that is mounted on a vehicle and stores electronic components is described, but the storage box according to the present invention may be applied to storage boxes other than the electrical junction box.

[0045] In the above embodiment, the cover 3 is installed as a storage box of the upper cover, but the cover 3 may be installed as a storage box of the lower cover. In addition, the cover 3 may be installed as a storage box of the upper cover and the lower cover.
