[0023] 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.

[0024] [Implementation Method]

[0025] A storage box according to an embodiment of the present invention will be described.

[0026] Figure 1 is an exploded perspective view of a storage box according to an embodiment. Figure 2 It is an explanatory diagram of a cushion member of a storage box according to an embodiment. Figure 3 yes Figure 1 A cross-sectional view of the storage box at III-III, Figure 4 yes Figure 1 A cross-sectional view of the storage box at III-III when the cover portion is installed.

[0027] like Figure 1As shown, the storage box 1 involved in the present embodiment is, for example, a box for storing electronic components, which is mounted on a vehicle and used as an electrical junction box, which stores 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 is a box member with an open upper surface, for example, in the form of a rectangular parallelepiped. The main body 2 can store electronic components inside, and an opening 21 is formed on the upper surface to connect the inside and the outside. The opening 21 of the main body 2 is closed by installing the cover 3. The opening 21 is, for example, an opening that opens the entire upper surface of the main body 2.

[0028] The hooked portion 23 is provided on the side wall 22 of the main body 2. The side wall 22 is a wall forming the side surface of the main body 2, and four are formed in the front, back, left and right. The hooked portion 23 is a portion hooked on the hooking portion 33 of the cover 3. The hooked portion 23 has a hooked piece 23A provided separately from the outer surface 22C of the side wall 22. One hooked portion 23 is provided at each upper portion of the two opposing side walls 22.

[0029] The cover 3 is an upper cover that covers the opening 21 of the main body 2, and can be mounted on the main body 2 in a manner that covers the opening 21. The cover 3 has a top surface 31 and a hanging portion 32. The top surface 31 is the upper surface portion of the cover 3, and is formed in a shape that matches the shape of the main body 2, for example, in a rectangular or substantially rectangular shape. The hanging portion 32 is a wall portion that extends downward from the outer edge of the top surface 31, and is formed over the entire circumference of the outer edge of the top surface 31. The cover 3 is provided with a hook portion 33. The hook portion 33 is a portion that engages with the hooked portion 23 of the main body 2 to hold and release the cover 3 relative to the main body 2. The hook portion 33 is, for example, provided on the outer surface 32A of the hanging portion 32, and is provided at a position corresponding to the hooked portion 23. The hook portion 33 and the hooked portion 23 together constitute a locking mechanism. The locking mechanism can be a locking mechanism of any structure as long as the cover 3 can be attached and detached relative to the main body 2.

[0030] The cushion member 4 is a waterproof member for waterproofing the main body 2 and the cover 3, and is formed of a resin. The cushion member 4 is formed of a resin having lower rigidity than the cover 3, for example, an elastic resin such as an elastomer. The cushion member 4 is provided, for example, by two-color molding. That is, the cushion member 4 is provided by two-color molding with the cover 3, and the cover 3 is resin-molded with a different resin after resin molding.

[0031] like Figure 3 As shown, the cushion member 4 is provided on the cover 3 and disposed between the main body 2 and the cover 3 to stop water between the main body 2 and the cover 3. The cushion member 4 is provided along the installation direction of the cover 3 (in Figure 3The cushion member 4 contacts the surface of the main body 2 formed in the direction parallel to the installation direction of the cover 3 to stop water. For example, the cushion member 4 contacts the side surface 22A of the side wall 22 of the main body 2 formed in parallel with the installation direction of the cover 3 to stop water. Here, parallel includes substantially parallel. The cushion member 4 is arranged in a groove 34 formed in the cover 3. The groove 34 is formed between the outer wall 35 and the inner wall 36 provided at the lower part of the hanging part 32. The hanging part 32 branches outward and inward at the lower part to form the inner wall 36 and the outer wall 35. The inner wall 36 is a wall portion formed at the lower part of the hanging part 32. The outer wall 35 is a wall portion branched outward through the protrusion 37, is located on the outer side of the inner wall 36, and is arranged parallel to the inner wall 36 at a predetermined distance from the inner wall 36. The protrusion 37 is arranged to protrude outward from the lower part of the hanging part 32, so that the outer wall 35 hangs down from the end. In addition, an extension portion 38 is formed continuously below the outer wall 35. The extension portion 38 is a wall portion that covers the outer side of the side wall 22 of the main body 2. The groove 34 is formed by the inner wall 36, the protrusion 37 and the outer wall 35, and is a space open at the bottom. The groove 34 extends along the extension direction of the lower edge of the hanging portion 32 (in Figure 3 The Y direction is formed.

[0032] The cushion member 4 has a water stopper 41 provided on the inner side surface 35A of the groove 34. The water stopper 41 is a portion that contacts the side surface 22A of the side wall 22 of the main body 2 inserted into the groove 34 to stop water. The water stopper 41 has a lip 41A that contacts the main body 2. The lip 41A is a protrusion with a mountain-shaped cross section, and protrudes toward the main body 2. For example, two lips 41A are provided, one along the insertion direction of the main body 2 (in the direction of insertion of the main body 2). Figure 3 The lip portion 41A is arranged side by side along the extension direction of the inner side surface 35A (in the Z direction). Figure 3 The inner side surface 35A is the inner side surface of the outer wall 35, and the water stop portion 41 and the lip portion 41A are formed on the outer side relative to the side wall 22 of the main body 2 inserted into the groove 34. In other words, the water stop portion 41 is formed only on one side of the side wall 22 of the main body 2. Figure 7As shown, the water stop portion 41 is sometimes formed on both sides of the side wall 22, but here, it is set in a manner that contacts the side surface of one of the inner side and the outer side of the side wall 22 of the main body 2. Therefore, when the cushion component 4 is molded by resin, the portion that becomes the undercut is reduced, so that the demolding of the cushion component 4 becomes easy and the manufacturability becomes good. In addition, when the cushion component 4 is molded by resin, even if the position of the gate that becomes the resin injection port is set on the opposite surface of the end face of the side wall 22, water stopping can be performed without hindering the water stopping function of the water stop portion 41. That is, even if there is a gate mark on the surface opposite to the end face of the side wall 22, since it is not necessary to make the end face of the side wall 22 contact with the cushion component 4, it will not affect the water stopping function of the water stop portion 41, and water stopping between the main body 2 and the cover 3 can be ensured.

[0033] The cover portion 3 is provided with a pressing portion 341. The pressing portion 341 is formed at a position opposite to the cushion member 4, and is a member that presses the main body 2 inserted between the pressing portion 341 and the cushion member 4 toward the cushion member 4. For example, the pressing portion 341 is formed on the inner side surface 36A of the groove 34, and presses the main body 2 inserted in the groove 34 toward the water stop portion 41. Specifically, the pressing portion 341 is formed to protrude from the inner side surface 36A of the inner wall 36 toward the water stop portion 41, and presses the side wall 22 of the main body 2 toward the water stop portion 41 provided on the inner side surface 35A. The protruding length of the pressing portion 341 is set so that the distance between the pressing portion 341 and the lip portion 41A of the water stop portion 41 is shorter than the thickness of the side wall 22 of the main body 2. Thus, the side wall 22 of the main body 2 can be pressed toward the lip portion 41A by the pressing portion 341. In addition, a tapered surface 341A is formed at the lower portion of the pressing portion 341. The tapered surface 341A is formed by inclining the surface of the pressing portion 341 that faces the water stop portion 41, and is inclined so that the protruding length of the pressing portion 341 decreases as it moves downward. That is, by forming the tapered surface 341A, the entrance of the groove 34 becomes wider, and the side wall 22 of the main body 2 can be smoothly inserted into the deep part of the groove 34. The pressing portion 341 is, for example, Figure 2 As shown, in the extension direction of the hanging portion 32 ( Figure 2 In addition, the pressing portion 341 is sometimes provided in the main body portion 2 instead of being provided in the cover portion 3.

[0034] exist Figure 3In the embodiment, the cover portion 3 is provided with a reinforcing rib 39. The reinforcing rib 39 is a component that is provided so as to engage with the surface of the cover portion 3 and that suppresses deformation of the outer wall 35 of the cover portion 3 at the position where the cushion member 4 is provided. For example, the reinforcing rib 39 is provided so as to engage with the surface 32A of the hanging portion 32 and the surface 37A of the protrusion 37 in the cover portion 3, thereby suppressing deformation of the outer wall 35. The reinforcing rib 39 is, for example, a triangular plate-shaped component that engages with the surface 37A of the protrusion 37 and the surface 32A of the hanging portion 32 that are orthogonal to each other, thereby suppressing movement of the protrusion 37 relative to the hanging portion 32. Thus, deformation and movement of the outer wall 35 and the extension portion 38 relative to the hanging portion 32 are suppressed. The reinforcing rib 39 is, for example, Figure 1 As shown, in the extension direction of the hanging portion 32 (in Figure 1 A plurality of them are formed at predetermined intervals (in the X direction and the Y direction).

[0035] exist Figure 3 In the embodiment, the side wall 22 of the main body 2 is provided with a protruding piece 24. The protruding piece 24 is a portion protruding from the side wall 22, and abuts against the hanging portion 32 of the cover 3 to restrict the cover 3 from moving downward. The protruding piece 24 is formed at a position on the upper part of the side wall 22, for example, so as to be connected to the entire circumference of the four side walls 22. Figure 3 As shown, the protruding piece 24 is formed on the outer surface of the side wall 22 and is arranged in a manner of abutting against the lower end of the outer wall 35. In this way, the protruding piece 24 abuts against the outer wall 35, so that the groove 34 is blocked by the protruding piece 24, and water etc. are inhibited from entering the groove 34 from the outside.

[0036] Next, the attachment of the cover portion to the storage box according to the present embodiment will be described.

[0037] like Figure 1 As shown, the cover 3 is arranged above the opening 21 of the main body 2, and the cover 3 is mounted on the main body 2 in such a manner that the opening 21 is covered by the cover 3. At this time, the cover 3 is arranged in such a manner that the position of the hooking portion 33 of the cover 3 is aligned with the position of the hooked portion 23 of the main body 2.

[0038] Then, if Figure 4 As shown, the cover 3 is approached from above the main body 2, and the side wall 22 is inserted into the groove 34. At this time, although the pressing portion 341 is provided in the groove 34, since the pressing portion 341 is formed with a tapered surface 341A, the side wall 22 is not hooked on the pressing portion 341 but is smoothly guided into the groove 34.

[0039] Then, the side wall 22 is inserted deep into the groove 34 while the lip 41A of the water stopper 41 is in contact with the side surface 22A of the side wall 22. Figure 4 The X direction in the figure) is not the installation direction of the cover 3 (in the Figure 4 The direction is not the same as the Z direction in the figure, but a direction intersecting with the installation direction, so that the installation of the cover 3 is carried out smoothly. Figure 5 When the end surface 122A of the side wall 122 is brought into contact with the gasket 104 to stop water, the installation direction of the cover 103 (in Figure 5 The contact direction with the pad 104 (in the Z direction) Figure 5 If the cover 103 is not pressed strongly against the gasket 104, the water-stopping property cannot be improved, and the installation of the cover 103 requires a strong installation force. In contrast, in the storage box 1 involved in this embodiment, the installation direction of the cover 3 and the contact direction of the water-stopping portion 41 are not the same direction, but a cross direction, so a strong installation force is not required when installing the cover 3. Therefore, the storage box 1 involved in this embodiment can ensure the water-stopping property of the main body 2 and the cover 3, and smoothly install the cover 3.

[0040] And, if Figure 3 As shown, the hanging portion 32 abuts against the protruding piece 24, and the cover portion 3 is embedded in the main body 2. In other words, the lower end of the outer wall 35 abuts against the protruding piece 24, and the insertion of the side wall 22 into the groove 34 is completed. At this time, the side wall 22 of the main body 2 is pressed against the water stop portion 41 by the pressing portion 341, so that the water stop between the main body 2 and the cover portion 3 can be improved. For example, if the pressing portion 341 is not formed, the side wall 22 may be tilted away from the water stop portion 41 and deformed (in Figure 3 In contrast, the storage box 1 according to the present embodiment can suppress such deformation of the side wall 22, and can reliably press the water stop portion 41 against the side wall 22 to stop water.

[0041] In addition, in the storage box 1 involved in the present embodiment, by providing the reinforcing ribs 39, the outer wall 35 and the extension portion 38 are suppressed from deforming in a manner of opening outward. Therefore, the reduction in the watertightness of the main body 2 and the cover 3 is suppressed. For example, assuming that the reinforcing ribs 39 are not provided, water pressure is applied from below the extension portion 38, or the side wall 22 presses the outer wall 35 via the waterstop portion 41, so that the outer wall 35 and the extension portion 38 may be deformed in a manner of opening outward. In contrast, in the storage box 1 involved in the present embodiment, the deformation of the outer wall 35 and the extension portion 38 can be suppressed by the reinforcing ribs 39, and the reduction in the watertightness of the main body 2 and the cover 3 is suppressed.

[0042] In addition, in the storage box 1 according to the present embodiment, since the water stop portion 41 contacts the side surface 22A of the side wall 22, the contact area can be enlarged, and the water stop property can be improved. Figure 5When the end face 122A of the side wall 122 is brought into contact with the gasket 104 to stop water, the length of the end face 122A (in Figure 5 The length in the X direction in the middle is narrowed, so the contact area between the side wall 122 and the gasket 104 is narrowed. Therefore, it is difficult to improve the water stopping performance. In contrast, the storage box 1 involved in this embodiment can expand the contact area between the side wall 22 and the water stopping portion 41, and can improve the water stopping performance.

[0043] Then, after the cover 3 is fitted to the main body 2, the hooking portion 33 is hooked on the hooked portion 23. Thus, the attachment of the cover 3 is completed.

[0044] As described above, according to the storage box 1 involved in this embodiment, the cushion member 4 is brought into contact with the surface of the main body 2 formed along the installation direction of the cover 3 to perform water stopping, so that the installation of the cover 3 does not require a strong force, and the water stopping function between the main body 2 and the cover 3 can be ensured by the water stopping portion 41. Therefore, the storage box 1 involved in this embodiment can smoothly install the cover 3 while ensuring water stopping performance.

[0045] Furthermore, the storage box 1 according to the present embodiment can press the main body 2 toward the water stopper 41 by forming the pressing portion 341 in the groove 34. Therefore, the water stopper property between the main body 2 and the cover 3 can be improved.

[0046] In the storage box 1 according to the present embodiment, the outer wall 35 can be prevented from deforming outward by providing the reinforcement ribs 39. Therefore, it is possible to prevent the water stopping function of the main body 2 and the cover 3 from being deteriorated.

[0047] In addition, in the storage box 1 involved in the present embodiment, the main body 2 is inserted into the groove 34 between the inner wall 36 and the outer wall 35, and the cushion member 4 provided on at least one of the inner wall 36 and the outer wall 35 is brought into contact with the side surface 22A of the main body 2 to stop water, so that the installation of the cover 3 does not require a strong force, and the water-stopping function between the main body 2 and the cover 3 can be ensured by the water-stopping portion 41. Therefore, the storage box 1 involved in the present embodiment can smoothly install the cover 3 while ensuring water-stopping performance.

[0048] In addition, in the storage box 1 involved in this embodiment, the water stop portion 41 of the cushion member 4 is formed only on one side of the inner wall 36 or the outer wall 35. Therefore, it is possible to reduce the portion that becomes the undercut when the cushion member 4 is resin-molded. Therefore, the cushion member 4 in the storage box 1 involved in this embodiment can be easily demolded, which can improve the manufacturability.

[0049] In addition, the storage box involved in the embodiment is described as above, but the storage box involved in the present invention is not limited to the above-mentioned embodiment, and various changes can be made within the scope described in the claims. In addition, the storage box involved in this embodiment can also be constructed by appropriately combining the constituent elements of the above-described embodiments and modified examples.

[0050] For example, in the above-mentioned embodiment, the case where the water stop portion 41 of the cushion member 4 contacts the outer side surface 22A of the side wall 22 of the main body 2 to stop water is described, but it is also possible to Figure 6 As shown, the water stop portion 41 contacts the inner side surface 22B of the side wall 22 to stop water. For example, the water stop portion 41 is provided on the inner side surface 36A of the inner wall 36, and contacts the side surface 22B of the side wall 22 to stop water. In this case, the same effect as the storage box 1 involved in the above-mentioned embodiment can also be obtained. In addition, in this case, the pressing portion 341 can also be provided protruding from the inner surface of the outer wall 35.

[0051] In the above-mentioned embodiment, the case where the water stop portion 41 of the cushion member 4 contacts only one side surface 22A of the side wall 22 of the main body 2 to stop water is described. Figure 7 As shown, the water stop portion 41 may also contact the side surface 22A and the side surface 22B on both sides of the side wall 22 to stop water. Figure 8 As shown, the positions in the height direction Z may be different between the lip portion 41A in contact with the side surface 22A and the lip portion 41B in contact with the side surface 22B. Figure 8 In, with Figure 7 In comparison, it is easier to demold the cushion member 4 during resin molding. Fig. 9 , Fig.10 As shown, the lip 41A in contact with the side 22A and the lip 41B in contact with the side 22B may be formed one by one. Fig. 9 , Fig.10 In, with Figure 7 Compared with the above, the portion that becomes the undercut is reduced, so it is easy to demold the pad member 4 during resin molding. Fig.10 In the embodiment, the positions of the lip 41A in contact with the side surface 22A and the lip 41B in contact with the side surface 22B are different in the height direction Z, so Fig. 9 In comparison, it is easier to demold the cushion member 4 during resin molding. Figure 7 to Figure 10Even in this case, the same effects as those of the storage box 1 according to the above-mentioned embodiment can be obtained. For example, since the water stop portion 41 of the cushion member 4 contacts the side of the main body 2 to stop water, the installation of the cover 3 does not require strong force, and the water stop function between the main body 2 and the cover 3 can be ensured by the water stop portion 41. Therefore, the cover 3 can be installed smoothly while ensuring water stop performance.

[0052] Furthermore, in the above-described embodiment, the case where the storage box is applied to an electrical connection box that is mounted on a vehicle and stores electronic components has been described, but the storage box according to the present invention may also be applied to a storage box that is not mounted on a vehicle.
