Description

Technical Field

[0001] The subject of this disclosure relates to a resin structure. Background Technology

[0002] In the prior art, a resin structure has been proposed that is constructed by mounting multiple resin bodies, such as an electrical junction box (e.g., a relay box) mounted on top of each other. For example, one prior art electrical junction box includes a box-shaped body for storing electronic components, etc., and a cover having a shape corresponding to the opening of the body to cover the opening. The cover is mounted to the body (see, for example, JP2020-150595A, JP2020-150596A, and JP2021-045019A).

[0003] Depending on the specifications of the electrical junction box, the interior of the main body can be divided into multiple areas, and the openings of each area can be covered by multiple covers corresponding to each area. For example, from the viewpoint of improving the maintainability of the electrical junction box, the areas can be designed so that relays are primarily stored in one area, while fuses are primarily stored in another. When such an electrical junction box is divided into multiple areas, and each area is covered by a cover in this way, the number of steps increases because the cover needs to be installed onto the main body while aligning it with the opening of the main body. Therefore, it is difficult to improve the productivity of the electrical junction box compared to a case where the main body has only a single area. Not limited to electrical junction boxes, in any resin structure with multiple internal areas and thus multiple covers installed onto the main body, it is similarly difficult to improve productivity compared to a resin structure with only a single internal area. Summary of the Invention

[0004] An illustrative aspect of the subject matter of this disclosure is a resin structure that enables the cover to be easily installed onto a body having multiple internal areas.

[0005] To achieve the above objectives, the resin structure according to the subject matter of this disclosure is characterized as follows.

[0006] According to an illustrative aspect of the subject matter of this disclosure, a resin structure includes: a body having a box shape and divided into a plurality of regions; and a cover configured to be mounted on the body and cover one of the plurality of regions. The body includes a first partition wall extending along a partition direction to separate a pair of adjacent regions among the plurality of regions. The cover is configured to cover one of the pair of regions and includes a second partition wall disposed at an edge of the cover such that it extends along the partition direction of the first partition wall. The first partition wall has a protrusion disposed at an end of the first partition wall along the partition direction, the protrusion projecting toward the second partition wall and connecting to the outer peripheral wall of the one of the regions, and has a first slope that gradually approaches the distal end of the protrusion in the partition direction from the distal end of the protrusion away from the first partition wall. The second partition wall has a second slope disposed at an end of the second partition wall, the end corresponding to the protrusion in the partition direction, the second slope being inclined along the first slope. When the body and the cover are mounted on each other, the cover is mounted onto the body while being guided by the second slope facing the first slope.

[0007] Other aspects and advantages of the subject matter of this disclosure will be set forth in the following description, drawings and claims. Attached Figure Description

[0017] In the following description, the accompanying drawings will be used as a reference. Figure 1 The resin structure 1 shown is an embodiment of the subject matter of this disclosure. The resin structure 1 is typically a relay box (electrical junction box) that will be installed in a vehicle and house electronic components such as relays.

[0018] like Figure 1 and Figure 2 As shown, the resin structure 1 includes a body 2 for accommodating electronic components such as relays (and other components not shown), and a first cover 3 mounted on the upper end of the body 2 to cover the upper opening of a first region R1 inside the body 2 (see Figure 1). Figure 2 ), and the second region R2 installed on the upper part of the main body 2 to cover the interior of the main body 2 (see Figure 2 A second cover (not shown) with an opening at its upper end. Each of the main body 2, the first cover 3, and the second cover is a resin-molded body. In this example, to prevent interference between the first cover 3 and components positioned above it when mounted on a vehicle (e.g., an oil reservoir), the first cover 3 is positioned below the second cover in the installed state of the resin structure 1. In the following description, each component forming the resin structure 1 will be described sequentially.

[0019] First, describe subject 2. For example... Figure 1 and Figure 2 As shown, the main body 2 has a tubular outer peripheral wall 11, which has a predetermined shape and extends in the vertical direction when viewed from above. The interior of the main body 2, surrounded by the outer peripheral wall 11, is divided into a first region R1 and a second region R2 by a flat, plate-like first partition wall 12 that passes through the interior of the main body 2 in a predetermined direction and extends in the vertical direction. In this example, the first region R1 and the second region R2 each house electronic components such as relays (and other components, not shown).

[0020] In the following text, the portion of the outer peripheral wall 11 that surrounds the first region R1 may be referred to as the first outer peripheral wall 11a, and the portion that surrounds the second region R2 may be referred to as the second outer peripheral wall 11b (see...). Figure 2In this example, in order to position the first cover 3 below the second cover in the installed state of the resin structure 1, the upper edge of the first outer peripheral wall 11a is positioned below the upper edge of the second outer peripheral wall 11b and the upper edge of the first partition wall 12.

[0021] In the following text, for ease of description, such as Figures 1 to 9 As shown, the "separation direction," "front-rear direction," and "up-down direction" are defined. The "separation direction," "front-rear direction," and "up-down direction" are orthogonal to each other. When the resin structure 1 is installed on a vehicle, the "up-down direction" corresponds to the up-down direction of the vehicle. The "separation direction" corresponds to the predetermined direction in which the first partition wall 12 extends inside the main body 2, while the "front-rear direction" corresponds to the thickness direction of the first partition wall 12.

[0022] like Figures 2 to 8 As shown, in the region below a predetermined distance below the upper edge on the rear end face of the first partition wall 12, a forward-recessed recess 13 is formed in a strip-like manner extending along the partitioning direction. Ribs 14 are provided at both ends (two locations) of the first partition wall 12 near its partitioning direction, protruding downwards from the upper edge of the recess 13 (the rear end of the sidewall defining the upper end of the recess 13). In the installed state of the resin structure 1, the recess 13 and ribs 14 engage with the second partition wall 23 (described later) of the first cover 3 (see [link to documentation]). Figure 4 and Figure 8 ).

[0023] At each end of the first partition wall 12 (more specifically, the groove 13) in the partitioning direction, a pair of protrusions 15 are formed that project rearward and extend in the vertical direction (see...). Figure 2 The lower ends of a pair of protrusions 15 are connected to the upper edge of the outer peripheral wall 11 (more specifically, the first outer peripheral wall 11a). A pair of first inclined surfaces 16 are formed on the inner sides of the pair of protrusions 15 in the separation direction (a pair of sides facing each other in the separation direction), which are inclined in a manner that gradually approaches the outer side in the separation direction as they move rearward (towards the distal side in the separation direction as they move away from the first partition wall 12) (see Figure 2 , Figure 5 (etc.) tilt. The effect achieved by setting a pair of first inclined planes 16 will be described later.

[0024] like Figure 2 As shown, a rearwardly protruding locking protrusion 17 is provided on the rear end face of the center portion (one position) in the partition direction of the first partition wall 12. In the installed state of the resin structure 1, the locking protrusion 17 engages with the locking arm of the second cover (described later).

[0025] like Figure 2As shown, engaging portions 18 are provided at multiple predetermined positions (two positions in this example) in the circumferential direction of the second outer peripheral wall 11b. These engaging portions 18 engage with multiple engaging portions (described later) of the second cover. Figure 2 As shown, engaging portions 19 are provided at multiple predetermined positions (two positions in this example) in the circumferential direction of the first outer peripheral wall 11a. The multiple engaging portions 19 engage with multiple engaging portions 24 (described later) of the first cover 3.

[0026] Next, the first cover 3 will be described. (As...) Figure 2 As shown, the first cover 3 integrally includes an outer peripheral wall 21 that has a shape corresponding to the first outer peripheral wall 11a of the main body 2 when viewed in the vertical direction and extends in the vertical direction, a top wall 22 that covers the upper opening surrounded by the outer peripheral wall 21, and a second partition wall 23 that protrudes upward from the front edge of the first partition wall 12 in the top wall 22 and extends in the partition direction. Engaging portions 24 that can engage with the engaging portions 19 are respectively provided at multiple positions (two positions) on the outer peripheral wall 21 corresponding to the multiple engaging portions 19 of the main body 2 in the circumferential direction.

[0027] At each end of the second partition wall 23 in the partitioning direction, there is a pair of inclined walls 25 corresponding to a pair of protrusions 15 of the main body 2 (see...). Figure 2 (etc.). A pair of inclined walls 25 slope from both ends of the second partition wall 23 in the partition direction as they move backward, gradually approaching the outer side in the partition direction (towards the far end in the partition direction as they move away from the second partition wall 23), and extend in the vertical direction. The sides of the pair of inclined walls 25 on the outer side in the partition direction (a pair of sides on the opposite side to the pair of sides facing each other in the partition direction) are a pair of second inclined surfaces 26 inclined along a pair of first inclined surfaces 16 of the main body 2 (see... Figure 2 , Figure 5 (etc.). That is, the pair of inclined surfaces 26 are inclined in such a way that they gradually approach the outer side in the partition direction as they move backward (towards the far end in the partition direction as they move away from the second partition wall 23). The lower ends of the pair of inclined walls 25 are connected to the upper surface of the top wall 22 of the first cover 3. The effect achieved by setting the pair of inclined surfaces 26 will be described later.

[0028] Next, the second cover will be described. The second cover (not shown) integrally includes an outer peripheral wall that has a shape corresponding to the second outer peripheral wall 11b of the main body 2 when viewed in the vertical direction and extends in the vertical direction; a third partition wall that extends in the partition direction corresponding to the first partition wall 12 and extends in the vertical direction in a manner connecting the two ends of the outer peripheral wall in the circumferential direction; and a top wall portion that covers the upper opening surrounded by the outer peripheral wall and the third partition wall. Engaging portions capable of engaging with the engaging portions 18 are provided at multiple positions (two positions) on the outer peripheral wall of the second cover that correspond to the multiple engaging portions 18 of the main body 2 in the circumferential direction.

[0029] A cantilevered locking arm extending downward from the third partition wall is provided at a position (a position) corresponding to the locking protrusion 17 of the main body 2 in the partitioning direction of the third partition wall. The locking arm elastically deforms in the front-rear direction within a predetermined range. The locking arm forms a rectangular opening that extends through in the front-rear direction. The lower edge of the opening locks to the locking protrusion 17 of the main body 2. The components forming the resin structure 1 have been described above.

[0030] Next, refer to Figures 2 to 4 The process of installing the first cover 3 and the second cover onto the main body 2 is described. First, the first cover 3 is installed onto the main body 2. To do this, the main body 2 and the first cover 3 are first arranged such that the first cover 3 is positioned above the first region R1 of the main body 2 (see...). Figure 2 Next, as Figure 3 As shown, when the first cover 3 is tilted in a direction that positions the front end of the first cover 3 below the rear end, the upper edge of the second partition wall 23 of the first cover 3 approaches the recess 13 of the main body 2 (see...). Figure 3 (See arrow in the image), the upper edge of the second partition wall 23 is received in the recess 13 such that the upper edge of the second partition wall 23 is positioned in front of a pair of ribs 14, and then the upper edge of the second partition wall 23 is locked to the upper corner of the recess 13 (the intersection between the side wall defining the upper end of the recess 13 and the bottom wall defining the front end of the recess 13) thereby extending across the entire area in the partition direction (see also...). Figure 8 ).

[0031] Here, when the first cover 3 is installed onto the main body 2, a pair of inclined walls 25 of the first cover 3 are sandwiched between a pair of protrusions 15 of the main body 2 in the separation direction, and a pair of second inclined surfaces 26 of the first cover 3 are guided by a pair of first inclined surfaces 16 facing the main body 2 (see...). Figure 5 This allows the second partition wall 23 to be accommodated in the recess 13. As described above, due to the guiding effect of the second inclined surface 26 along the first inclined surface 16, the positional deviation of the first cover 3 relative to the main body 2 in the partitioning direction is prevented, and the first cover 3 is naturally positioned at an appropriate location in the partitioning direction for covering the first region R1.

[0032] Next, as Figure 4 As shown, the first cover 3 rotates about the upper edge of the second partition wall 23 (i.e., the front end of the first cover 3) about the direction in which the rear end of the first cover 3 moves downward (the direction in which the first cover 3 returns to a horizontal position) locked to the upper corner of the recess 13 (see...). Figure 4 (See the arrow in the image). Thus, the first cover 3 is installed onto the main body 2 such that the outer peripheral wall 21 of the first cover 3 overlaps with the outer side of the first outer peripheral wall 11a of the main body 2 (see the image). Figure 4 Therefore, the assembly of the first cover 3 to the main body 2 was completed.

[0033] After the first cover 3 is assembled into the main body 2, as follows: Figure 8 As shown, the second partition wall 23 is accommodated in the recess 13. Therefore, when the upper end face of the second partition wall 23 engages with the inner wall face of the side wall defining the upper end of the recess 13, separation of the front end of the first cover 3 from the main body 2 in the vertical direction is prevented. In other words, separation of the front end of the first cover 3 from the main body 2 in the vertical direction is prevented without the need for a separate locking structure or the like for fixation. Furthermore, by engaging the rear end face of the upper edge of the second partition wall 23 with the front end face of the rib 14, movement of the second partition wall 23 in a direction away from the first partition wall 12 (rearward) is prevented. Therefore, once the main body 2 and the first cover 3 are installed, the first cover 3 is more securely prevented from accidentally falling off the main body 2. In addition, due to the locking part 19a provided in the engaging part 19 of the main body 2 (see... Figure 9 ) and the locking part 24a provided in the engaging part 24 of the first cover 3 (see Figure 9 ) mutually locked together (see Figure 1 , Figure 2 ,as well as Figure 9 Therefore, it prevents the rear end of the first cover 3 from separating from the main body 2 in the vertical direction.

[0034] Furthermore, after the first cover 3 has been assembled into the main body 2, such as Figure 8 As shown, by overlapping (layering) the first partition wall 12 of the main body 2 and the second partition wall 23 of the first cover 3 in the front-to-back direction, a multi-layered wall structure (specifically, a double-wall structure; a so-called labyrinth structure) is formed. Therefore, compared with the case where the first partition wall 12 and the second partition wall 23 are simply installed on each other, the flow distance is longer, and water can be prevented from entering the interior of the main body 2 from between adjacent areas R1 and R2.

[0035] Furthermore, after the first cover 3 has been assembled into the main body 2, such as Figure 6 and Figure 7 As shown, a pair of second inclined surfaces 26 are in contact with a pair of first inclined surfaces 16 (or are arranged facing each other with a small distance between them). Therefore, by visually observing the positional relationship between the pair of second inclined surfaces 26 and the pair of first inclined surfaces 16, it is easy to identify whether the first cover 3 is positioned appropriately relative to the body 2. Furthermore, since a pair of protrusions 15 extending from the first partition wall 12 of the body 2 are connected to the first outer peripheral wall 11a of the body 2, the rigidity of the body 2 is increased. Moreover, since a pair of inclined walls 25 extending from the second partition wall 23 of the first cover 3 are connected to the top wall 22 of the first cover 3, the rigidity of the first cover 3 is increased. Therefore, when the first cover 3 is installed onto the body 2, deformation of the body 2 and the first cover 3 can be prevented.

[0036] Next, as Figure 4As shown, the second cover is installed onto the main body 2, on which the first cover 3 has already been installed. To do this, firstly, the main body 2 and the second cover are arranged such that the second cover is positioned above the second region R2 of the main body 2. Next, with the second cover remaining horizontal, the main body 2 and the second cover approach each other vertically. Thus, the second cover is installed onto the main body 2 such that the third partition wall of the second cover overlaps with the rear side of the first partition wall 12 of the main body 2, and the outer peripheral wall of the second cover overlaps with the outer side of the second outer peripheral wall 11b of the main body 2. Therefore, the assembly of the first cover 3 and the second cover onto the main body 2 is completed, and the resin structure 1 is obtained with the installation completed.

[0037] With the second cover assembled to the main body 2 (in the installed state of resin structure 1), the lower edge of the opening of the locking arm of the second cover engages with the locking protrusion 17 of the main body 2, and the engaging portion 18 of the main body 2 engages with the engaging portion of the second cover. Therefore, separation of the main body 2 and the second cover in the vertical direction is prevented.

[0038] As described above, according to the resin structure 1 of this embodiment, when the first cover 3 is installed to cover region R1 of the plurality of regions R1 and R2 of the box-shaped body 2, the first cover 3 is guided such that the second inclined surface 26 of the first cover 3 faces the first inclined surface 16 of the protrusion 15 that protrudes from the end of the first partition wall 12 provided in the body 2 to separate regions R1 and R2. Here, the first inclined surface 16 is inclined such that it gradually approaches the distal end in the partition direction as it moves away from the first partition wall 12, and the second inclined surface 26 is inclined along the first inclined surface 16. Therefore, when the first cover 3 is installed on the body 2, the first cover 3 is naturally arranged in the proper position, thereby covering region R1 by the guiding effect of the second inclined surface 26 being guided along the first inclined surface 16. Furthermore, since the protrusion 15 protrudes from the first partition wall 12 and connects to the outer peripheral wall 11a of region R1, the rigidity of the body 2 is increased. Therefore, accidental deformation of the body 2 can be prevented. The prevention of deformation of the body 2 helps to arrange the first cover 3 in the proper position. Therefore, the resin structure 1 according to this embodiment enables the first cover 3 to be easily installed onto the body 2 having multiple internal regions R1 and R2.

[0039] Furthermore, the aforementioned protrusions 15 are provided at both ends of the first partition wall 12 in the partitioning direction. Therefore, when the first cover 3 is installed onto the main body 2, the first cover 3 is sandwiched between the two protrusions 15 in the partitioning direction and guided to the appropriate position to cover the area R1. Therefore, the resin structure 1 according to this embodiment enables the first cover 3 to be easily installed onto the main body 2.

[0040] Furthermore, when the first cover 3 is installed onto the main body 2 forming the resin structure 1, the first partition wall 12 of the main body 2 and the second partition wall 23 of the first cover 3 overlap each other, thereby forming a multi-layered wall structure (a so-called labyrinth structure). This multi-layered wall structure increases the flow distance between the main body 2 and the first cover 3, thereby preventing water from entering the interior of the resin structure 1 from the boundary between adjacent regions R1 and R2. That is, the waterproof performance of the resin structure 1 can be improved.

[0041] Furthermore, the recess 13 provided in the first partition wall 12 of the main body 2 restricts the movement of the second partition wall 23 of the first cover 3 in a direction away from the main body 2. Therefore, for example, when the first cover 3 is to be installed onto the main body 2, the first cover 3 can rotate around the contact point between the recess 13 of the main body 2 and the first cover 3 to be installed onto the main body 2. In addition, since the movement of the first cover 3 is restricted by the recess 13, the first cover 3 can be prevented from falling off the main body 2 without the need for a separate locking structure for fixing. Therefore, by omitting such a locking structure, the internal space of the main body 2 is expanded and the storage performance of the resin structure 1 is improved. In addition, since it is not necessary to provide such a locking structure on the outer peripheral wall 11 of the main body 2, the size of the resin structure 1 can be reduced.

[0042] Although the subject matter of this disclosure has been described with reference to certain exemplary embodiments thereof, the scope of the subject matter of this disclosure is not limited to the exemplary embodiments described above, and those skilled in the art will understand that various modifications and alterations may be made therein without departing from the scope of the subject matter of this disclosure as defined by the appended claims.

[0043] In the above embodiment, both ends of the first partition wall 12 of the main body 2 in the partitioning direction are provided with protrusions 15, each having a first inclined surface 16. On the other hand, one end of the first partition wall 12 of the main body 2 in the partitioning direction may also be provided with a protrusion 15 having a first inclined surface 16.

[0044] According to an aspect of the above embodiment, a resin structure (1) includes: a body (2) having a box shape and divided into a plurality of regions (R1, R2); and a cover (3) configured to be mounted on the body (2) and cover one of the plurality of regions (R1). The body (2) includes a first partition wall (12) extending along a partitioning direction to separate a pair of adjacent regions (R1, R2) among the plurality of regions. The cover (3) is configured to cover one of the pair of regions (R1) and includes a second partition wall (23) disposed at an edge of the cover (3) such that it extends along the partitioning direction of the first partition wall (12). The first partition wall (12) has a protrusion (15) disposed at its end along the partition direction, the protrusion (15) protruding toward the second partition wall (23) and connected to the outer peripheral wall (11a) of the region (R1), and has a first inclined surface (16) that gradually approaches the distal end of the protrusion (15) away from the first partition wall (12) in the partition direction. The second partition wall (23) has a second inclined surface (26) disposed at its end corresponding to the protrusion (15) in the partition direction, the second inclined surface (26) being inclined along the first inclined surface (16). When the body (2) and the cover (3) are installed together, the cover (3) is installed onto the body while being guided by the second inclined surface (26) facing the first inclined surface (16).

[0045] According to the resin structure having the above-described configuration, when the cover is to be installed to cover one of the multiple areas of the box-shaped body, it is guided by the second inclined surface of the cover towards the first inclined surface of the protrusion that extends from the end of the first partition wall disposed in the body and dividing the area. Here, the first inclined surface is inclined such that it gradually approaches the distal end in the partitioning direction as it moves away from the first partition wall, and the second inclined surface is inclined along the first inclined surface. Therefore, when the cover is to be installed on the body, the cover is naturally positioned in place, thereby covering the area corresponding to the cover by the guiding action of being guided by the second inclined surface along the first inclined surface. Furthermore, since the protrusion protrudes from the first partition wall and connects to the outer peripheral wall of a region, the rigidity of the body is increased. Therefore, accidental deformation of the body can be prevented. The prevention of deformation of the body helps to position the cover in place. Therefore, the resin structure having this configuration enables the cover to be easily installed on a body having multiple internal areas.

[0046] The first partition wall (12) may have the protrusions (15) at both ends in the partitioning direction of the first partition wall (12).

[0047] With this construction, the aforementioned protrusions are provided at both ends of the first partition wall in the partitioning direction. Therefore, when the cover is installed onto the body, the cover is sandwiched between the two protrusions in the partitioning direction and guided to the appropriate position to cover the area corresponding to the cover. Thus, the resin structure with this construction allows the cover to be easily installed onto the body.

[0048] When the main body (2) and the cover (3) are installed together, the first partition wall (12) and the second partition wall (23) can be arranged to overlap each other in the thickness direction of the first partition wall (12) to form a multi-layer wall structure.

[0049] According to the resin structure having the above-described [3] construction, when the cover is installed onto the main body forming the resin structure, the first partition wall of the main body and the second partition wall of the cover overlap each other, thereby forming a multi-layered wall structure (so-called labyrinth structure). Through this multi-layered wall structure, the flow distance between the main body and the cover is increased, thereby preventing water from entering the interior of the resin structure from the boundary between adjacent areas. That is, the waterproof performance of the resin structure can be improved.

[0050] The first partition wall (12) may have a concave limiting portion (13) configured to accommodate at least a portion of the second partition wall (23) and restrict the second partition wall (23) from moving in a direction away from the body (2).

[0051] According to the resin structure having the above-described [4] configuration, the concave limiting portion provided in the first partition wall of the main body restricts the movement of the second partition wall of the cover in a direction away from the main body. Therefore, for example, when the cover is to be installed onto the main body, the cover can rotate around the contact point between the limiting portion of the main body and the cover to be installed onto the main body. In addition, since the movement of the cover is restricted by the limiting portion, the cover can be prevented from falling off the main body without the need for a separate locking structure for fixing. Therefore, by omitting such a locking structure, the internal space of the main body is expanded and the storage performance of the resin structure is improved. In addition, since it is not necessary to provide such a locking structure on the outer peripheral wall of the main body, the size of the resin structure can be reduced.
