Description

[Technical Field]

[0001] The present invention relates to a vehicle storage structure provided outside a passenger compartment of a vehicle. [Background technology]

[0002] 2. Description of the Related Art Numerous vehicle components are mounted outside the vehicle cabin, more specifically, below the bonnet hood. Specifically, the vehicle equipment refers to radiators, fans, air conditioners, air cleaners, storage structures for storing and holding items, engines in gasoline and diesel vehicles, and motors and batteries in electric vehicles.

[0003] On the other hand, a typical vehicle has a metal body as a structure for ensuring rigidity. The body extends in the vehicle travel direction and width direction, and is also located below the hood.

[0004] In order to avoid interference between the body and various vehicle equipment arranged below the bonnet hood, a portion of the body below the bonnet hood is generally made discontinuous in the direction of vehicle travel and / or the vehicle width to ensure space for mounting the vehicle equipment (see, for example, Patent Document 1).

[0005] Patent Document 1 describes that side frames (front side frames 16, 16), which are part of the body, are spaced apart in the vehicle width direction below the bonnet hood (bonnet 56). It also describes that a bumper reinforcement 74 and an instrument panel member 30, which are also part of the body, are spaced apart in the vehicle traveling direction.

[0006] Patent document 1 also explains that vehicle equipment such as a radiator 50, an air cleaner 60, and a front trunk box 98 are mounted between the above-mentioned front side frames 16, 16 and between the bumper reinforcement 74 and the instrument panel member 30.

[0007] By separating and discontinuing parts of the body in the vehicle width direction and the vehicle travel direction in this way, it is possible to ensure space therein for mounting various vehicle equipment.

[0008] On the other hand, if a portion of the body below the bonnet hood is discontinuous in the vehicle travel direction and / or width direction, the rigidity of the body will decrease in the discontinuous portion. For this reason, various reinforcing structures such as upper cross members, lower cross members, upper sides, front faces, radiator supports, etc. are generally attached to the body, and the body is reinforced by bridging these reinforcing structures across the discontinuous parts of the body. Patent Document 1 also describes that the discontinuous portion of the body is reinforced by a reinforcing structure such as a front cross member 18. [Prior art documents] [Patent documents]

[0009] [Patent Document 1] Japanese Patent Application Laid-Open No. 2005-29103 Summary of the Invention [Problem to be solved by the invention]

[0010] In order to more fully reinforce the discontinuous portions of the body, it is considered effective to provide multiple reinforcing structures for reinforcing the discontinuous portions of the body and to reinforce the body at multiple locations. The more reinforcing structures there are, the more strongly the body can be reinforced.

[0011] However, when many reinforcing structures are attached to the body, the number of attachment points between the body and the reinforcing structures also increases accordingly.

[0012] The body and each reinforcing structure have some dimensional variation. In recent years, due to the demand for weight reduction, various parts of a vehicle are made of resin materials. However, when the reinforcing structure is made of resin material, the dimensional variation is particularly large.

[0013] The above-mentioned dimensional variations of the reinforcing structure are closely related to the relative positional relationship between the body and the reinforcing structure. In other words, if the relative positions of the body and the reinforcing structure are significantly different, it may be difficult for the reinforcing structure to sufficiently reinforce the body.

[0014] Thus, although the area below the hood of a vehicle is required to have both the function of mounting various vehicle equipment and the function of reinforcing the body, it has been difficult to achieve both of these functions sufficiently. Hereinafter, the area below the hood of a vehicle may be referred to as the "under-hood area" as necessary.

[0015] The present invention has been made in view of the above circumstances, and an object to be achieved is to provide a technique that can contribute to improving the functionality of the area under the hood of a vehicle. [Means for solving the problem]

[0016] The inventors of the present invention sought to improve the functionality of the under-hood area of ​​a vehicle by creating a discontinuous portion in the body to provide the under-hood area with the functionality to mount various vehicle equipment, and to find a method for fully reinforcing the discontinuous portion. In the process, they noticed that high rigidity could be imparted to the storage structure for the vehicle equipment.

[0017] The storage structure, which is one type of vehicle equipment, is also called a front trunk box, a front trunk, or a frunk, and is a box-shaped member having a storage space for storing items. Because of its box shape, the storage structure can be said to have a structure in which it is relatively easy to improve its rigidity.

[0018] The inventors of the present invention aimed to improve the rigidity of the storage structure and to use the storage structure to reinforce discontinuous portions of the body.

[0019] It is considered preferable that the storage structure has a large storage space so that it can store as many or as many large items as possible. Also, due to the demand for weight reduction mentioned above, the storage structure is generally designed to be made of a resin material and to have a relatively thin wall shape. For this reason, despite the box-like structure, the rigidity of a typical storage structure is relatively low.

[0020] For example, in Patent Document 1, a front trunk box 98, which is a storage structure, is reinforced by attaching it to a trunk pan 99, and the trunk pan 99 is further reinforced by attaching it to a front cross member 18 via a bracket 102.

[0021] Therefore, the conventional storage structure does not have enough rigidity to fully reinforce the body, and because the storage structure is attached to the body via multiple members, it is prone to shifting position relative to the body. In other words, the conventional storage structure introduced in Patent Document 1 is not suitable for reinforcing the body.

[0022] The inventors of the present invention have further conducted extensive research and have invented the vehicle storage structure of the present invention.

[0023] The vehicle storage structure of the present invention, which solves the above problems, comprises: A vehicle storage structure made of a resin material and arranged below a bonnet hood outside a vehicle compartment, a box-shaped main body having a storage space; a pair of mounting portions formed integrally with the main body portion, constituting a part of the metal body and being attached to two body portions spaced apart from each other; a body reinforcement structure formed integrally with the main body, The body reinforcement structure is a vehicle storage structure provided in at least a part of a reinforcement region of the main body extending from one of the pair of mounting portions to the other. [Effects of the Invention]

[0024] According to the vehicle storage structure of the present invention, it is possible to improve the functionality of the under-hood area of ​​a vehicle. [Brief explanation of the drawings]

[Figure 7] FIG. 10 is an explanatory diagram illustrating a vehicle storage structure 1 according to a third embodiment, as viewed from above. DETAILED DESCRIPTION OF THE INVENTION

[0026] Hereinafter, the vehicle storage structure of the present invention will be described with reference to specific examples. Unless otherwise specified, the term "front" simply refers to the front side in the direction of travel of the vehicle, and the term "rear side" simply refers to the rear side in the direction of travel of the vehicle.

[0027] Unless otherwise specified, the numerical ranges "x to y" described in this specification include the lower limit x and the upper limit y. These upper and lower limit values, as well as the numerical values ​​listed in the embodiments, can be arbitrarily combined to form a numerical range. Furthermore, the upper and lower limit values ​​can be arbitrarily selected from within the numerical range.

[0028] The vehicle storage structure of the present invention is disposed in the under-hood area, i.e., below the bonnet hood outside the passenger compartment of the vehicle. The bonnet hood here refers to a hood on either the front or rear side of the vehicle, which is used to open and close the motor compartment in which the motor and, if necessary, the battery are stored in an electric vehicle, and a hood used to open and close the engine compartment in which the engine is stored in an internal combustion vehicle.

[0029] The vehicle storage structure of the present invention is a vehicle storage structure made of a resin material and arranged below a bonnet hood outside a vehicle compartment, a box-shaped main body having a storage space; a pair of mounting portions formed integrally with the main body portion, constituting a part of the metal body and being attached to two body portions spaced apart from each other; a body reinforcement structure formed integrally with the main body, The body reinforcement structure is a vehicle storage structure provided in at least a part of a reinforcement region of the main body extending from one of the pair of mounting portions to the other.

[0030] The main body is box-shaped with a storage space and can literally be called the main body of the vehicle storage structure of the present invention. Because the main body is box-shaped, it can be said that it is easy to exhibit excellent structural rigidity.

[0031] The vehicle storage structure of the present invention includes, in addition to the main body, a pair of mounting portions and a body reinforcement structure. Since the pair of mounting portions and the body reinforcement structure are formed integrally with the main body, the main body, the pair of mounting portions and the body reinforcement structure are firmly integrated with each other without the use of any other member.

[0032] The pair of mounting portions of the vehicle storage structure of the present invention are attached to two body parts, respectively. Therefore, the vehicle storage structure of the present invention can be said to be attached to two body parts that are parts of the body of a vehicle by the pair of mounting portions and to span between the two body parts.

[0033] The two body portions are components that constitute a part of the metal body and are separated from each other. Therefore, it can be said that the discontinuous portion of the body is formed between the two body portions, and the vehicle storage structure of the present invention can be said to reinforce the discontinuous portion of the body.

[0034] Specific examples of body parts include, but are not limited to, bumper reinforcements (front cross members), side members, crash boxes, dash panels, and front inside panels. The two body parts may be, for example, two different parts selected from the various body parts described above. Alternatively, if one of the body parts is one of a pair of members, such as a side member, the other of the pair may be selected as the other body part. In other words, in this case, one of the body parts may be one of a pair of side members, and the other body part may be the other of the pair of side members. For reference, the above-mentioned body parts are arranged in the following order from the front to the rear in the vehicle's travel direction: bumper reinforcement, crash box, side member, front inside panel, and dash panel.

[0035] As an example, it is preferable to adopt any one of the following combinations of [a] to [c] as the combination of two body parts to which each of the pair of mounting parts is attached. [a] Left side member and right side member, [b] Left front inside panel and right front inside panel, [c] Left crash box and right crash box. The combinations of the two body parts listed in [a] to [c] above are all spaced apart from each other in the vehicle width direction. Therefore, when any of the combinations [a] to [c] above is used as the combination of the two body parts to which each of the pair of mounting parts is attached, it can be said that the vehicle storage structure of the present invention reinforces the body in the vehicle width direction.

[0036] As another example, it is preferable to adopt any one of the following combinations [d] to [n] as the combination of two body parts to which each of the pair of mounting parts is attached. [d] Left side member and left front inside panel, [e] Right side member and right front inside panel, [f] Left side crash box and left side front inside panel, [g] Right side crash box and right side front inside panel, [h] Bumper reinforcement and left side member, [i] Bumper reinforcement and right side member, [j] Left front inside panel and dash panel, [k] Right front inside panel and dash panel, [l] Bumper reinforcement and dash panel, [m] Left side member and dash panel, [n] Right side member and dash panel. The combinations of two body parts listed above in [d]-[n] are all spaced apart from each other in the vehicle travel direction. Therefore, when any of the combinations [d]-[n] above is used as the combination of two body parts to which each of the pair of mounting parts is attached, it can be said that the vehicle storage structure of the present invention reinforces the body in the vehicle travel direction.

[0037] In the vehicle storage structure of the present invention, the body reinforcement structure is provided in the reinforced region of the main body, i.e., in at least a part of the region of the main body extending from one of the pair of mounting portions to the other. This body reinforcement structure reinforces the main body, improving the rigidity of at least the reinforced region of the main body. As a result, the vehicle storage structure of the present invention acquires rigidity sufficient to fully reinforce discontinuous portions of the body.

[0038] The vehicle storage structure of the present invention is directly connected to two body parts of the body and reinforces the discontinuous portion of the body without using any other members. Therefore, the vehicle storage structure and the body are connected with a minimum number of members, and the problem of misalignment of the storage structure relative to the body as described above is unlikely to occur.

[0039] Due to the cooperation of the above, the vehicle storage structure of the present invention can be said to be suitable for reinforcing the body, unlike conventional storage structures. Furthermore, in a vehicle equipped with the vehicle storage structure, even if a discontinuous portion is provided in the body to provide the function of mounting various vehicle equipment in the under-hood area, the vehicle storage structure of the present invention can fully reinforce the discontinuous portion. Furthermore, the vehicle storage structure of the present invention has a function of reinforcing the body in addition to a function of storing and holding items. In other words, the vehicle storage structure of the present invention provides the under-hood area with the function of storing and holding items while also reinforcing the body itself, thereby contributing to space saving in the under-hood area. Therefore, it can be said that the vehicle storage structure of the present invention can improve the functionality of the under-hood area of ​​a vehicle.

[0040] Hereinafter, the vehicle storage structure of the present invention will be described in detail with respect to each of its components.

[0041] The vehicle storage structure of the present invention is made of a resin material. In this specification, the term "resin material" refers to a material containing resin. The resin content in the resin material is not particularly limited, but from the viewpoint of reducing the weight of the vehicle storage structure of the present invention, the resin preferably accounts for 30% by mass or more, 50% by mass or more, or 70% by mass or more when the entire resin material is taken as 100% by mass. It is particularly preferable that the resin account for 50% by mass or more.

[0042] The resin material may contain additives other than resin. It is preferable to select additives that have a reinforcing function for the vehicle storage structure. Specifically, the additives may be at least one selected from the group consisting of talc, inorganic fillers, glass fiber (GF), carbon fiber (CF), and fibrous magnesium compounds derived from magnesium hydroxide. Resin materials containing reinforcing fibers such as GF and CF are also called fiber-reinforced plastics (FRP). When the resin material is an FRP material, the resin may be a thermosetting resin such as an epoxy resin, or a thermoplastic resin such as PP or PA.

[0043] Examples of resins in the resin material include polypropylene (PP), polyamide (PA), polyethylene terephthalate (PET), acrylonitrile-butadiene-styrene copolymer synthetic resin (ABS), and polycarbonate (PC). It is preferable to use one or more of these resins. From the viewpoint of increasing the rigidity of the vehicle storage structure of the present invention, it is preferable that the resin material contains at least one selected from polypropylene and polyamide as a main component and / or be an FRP material. The term "main component" as used herein means a component that accounts for 70% by mass or more of the resin.

[0044] The vehicle storage structure of the present invention may have different resin material compositions for different parts, but considering ease of manufacture and improved rigidity of the vehicle storage structure as a whole, it is preferable to form the entire vehicle storage structure from resin materials of the same composition.

[0045] The vehicle storage structure of the present invention comprises a main body portion, a mounting portion, and a body reinforcing structure portion. The main body is box-shaped and has a storage space therein. The size and shape of the main body can be appropriately designed depending on the size of the items to be stored in the storage space, the size of the discontinuous portion of the body to be reinforced with the vehicle storage structure of the present invention, etc.

[0046] The main body may be a box-shaped body that opens upward, a box-shaped body that opens to the side, or a box-shaped body that opens downward in some cases. The main body may also have a lid for closing the opening.

[0047] The main body has walls such as a bottom wall, a top wall, and a peripheral wall to form a box shape. One of the walls is bent or curved relative to at least one of the other walls to form a continuous vertical wall. This continuous portion of the walls provides the main body with a certain degree of rigidity. Therefore, the main body itself can also have a reinforcing function for reinforcing discontinuous portions of the body.

[0048] In order to enhance the reinforcing function of the main body, it is effective to use a resin material containing a high-strength resin such as the above-mentioned PA or FRP, but it is also effective to make the main body thicker.

[0049] Specifically, the thickness of the main body is preferably within the range of 1 to 7 mm. For example, if the resin material of the main body is FRP made of PP and GF, the thickness of the main body is preferably 2 mm or more.

[0050] The vehicle storage structure of the present invention has a pair of mounting portions that are formed integrally with the main body portion and are attached to two body portions of the body as described above. Note that the vehicle storage structure of the present invention may have only one pair of mounting portions, or may have multiple pairs of mounting portions. Furthermore, each of the attachment portions may have the same shape, or at least one of them may have a different shape.

[0051] One of the pair of mounting parts is attached to one of the two body parts, and the other of the pair of mounting parts is attached to the other of the two body parts. The mounting parts may have any shape that allows them to be attached to the corresponding body parts, and may be, for example, in the form of a through hole that is attached to the body part via an attachment member such as a bolt, or may be in the form of a claw or hook that is attached directly to the body part.

[0052] The attachment portion may be formed directly on the peripheral wall or bottom wall of the main body, on a flange that surrounds at least a portion of the periphery of the opening of the main body, or on a leg that extends in a strip shape from the main body.

[0053] However, from the viewpoint of improving the rigidity of the vehicle storage structure of the present invention, it is preferable that the mounting portion is located close to the main body portion, and is preferably formed on a flange surrounding at least a part of the periphery of the opening of the main body portion, or is preferably formed directly on the peripheral wall, bottom wall, etc. of the main body portion. It is particularly preferable that at least one of the mounting portions is a through-hole and is formed directly on the bottom wall or peripheral wall of the main body portion.

[0054] The vehicle storage structure of the present invention spans between two body parts and reinforces the discontinuous portion of the body. In such a vehicle storage structure of the present invention, when one body part is pressed toward the other body part, for example, during a collision, this pressing force is transmitted from the one body part to the main body part via one of the mounting parts attached thereto, and further transmitted to the other body part via the other mounting part. Therefore, the reinforcing performance of the vehicle storage structure of the present invention to reinforce the body is greatly related to the positional relationship between the mounting part and the main body part.

[0055] Specifically, in order to efficiently reinforce the body with the vehicle storage structure of the present invention, it is preferable that the mounting portion and the main body portion are arranged linearly. For example, the pair of mounting portions are preferably positioned below the upper end of the main body portion and above the lower end of the main body portion when attached to the body portion. This attached state can also be referred to as a state in which the vehicle storage structure of the present invention is mounted on a vehicle.

[0056] In order to reinforce the body more efficiently with the vehicle storage structure of the present invention, it is effective to reduce the amount of compressive deformation of the vehicle storage structure that spans two body parts. In order to reduce the amount of compressive deformation of the vehicle storage structure, it is preferable that the pair of mounting parts be located more inward than the main body part in the direction connecting the pair of mounting parts. Hereinafter, the direction connecting the pair of mounting parts may be referred to as the reinforcement direction as necessary.

[0057] For example, if the two body parts are spaced apart in the front-rear direction, the pair of mounting parts are arranged in the front-rear direction. In this case, the reinforcement direction is the front-rear direction. In this case, the pair of mounting parts are preferably located rearward of the front end of the main body part and forward of the rear end of the main body part. In other words, the pair of mounting parts are preferably located rearward of the front end of the main body part and forward of the rear end of the main body part in the mounted state.

[0058] Furthermore, for example, when the two body portions are spaced apart in the vehicle width direction, the pair of mounting portions are arranged in the vehicle width direction. In this case, the reinforcement direction is the vehicle width direction. In this case, it is preferable that the pair of mounting portions be located closer to the other end of the main body portion in the vehicle width direction than the one end of the main body portion in the vehicle width direction. In other words, it is preferable that the pair of mounting portions be located closer to the other end of the main body portion in the vehicle width direction than the one end of the main body portion in the vehicle width direction when mounted.

[0059] The vehicle storage structure of the present invention includes a body reinforcement structure formed integrally with the main body. As described above, the body reinforcement structure has the function of reinforcing the main body and, in turn, reinforcing the body.

[0060] The body reinforcement structure is provided in at least a part of a reinforced region of the main body, which is a region of the main body that extends from one of the pair of mounting portions to the other. When one of the two body parts is pressed toward the other, such as during an impact, one of the pair of mounting parts is pressed toward the other, and a compressive force acts on the reinforced area of ​​the main body part.

[0061] In the vehicle storage structure of the present invention, a body reinforcing structure is provided in at least a portion of the reinforced region. The reinforced region reinforced by the body reinforcing structure is thus resistant to compressive deformation, and the main body having the reinforced region, and therefore the vehicle storage structure of the present invention including the main body, is also resistant to compressive deformation. As a result, the vehicle storage structure of the present invention can reinforce discontinuous portions of the body efficiently and reliably.

[0062] The body reinforcing structure in the vehicle storage structure of the present invention may have sufficient rigidity to reinforce the main body due to its structure and / or its material.

[0063] For example, the rigidity of the body reinforcement structure can be structurally improved by making the thickness of the body reinforcement structure greater than the average thickness of the main body. Note that the thickness of the body reinforcement structure here refers to the length of the body reinforcement structure in the same direction as the thickness of the portion of the main body to which the body reinforcement structure is integrated.

[0064] The average thickness of the main body may be the average of all thicknesses of the main body, or may be a correction value that avoids the influence of other structures integrally formed with the main body, such as mounting portions and body reinforcement structures. Specifically, the correction value may be a measurement of the bottom wall of the main body or, in some cases, the top wall of the main body. These measurement points may be any five or more locations on the bottom or top wall of the main body that are at least 5 mm away from other structures, such as mounting portions, body reinforcement structures, various reinforcing ribs, and partitions. The correction value may then be the average of six or more intermediate values ​​obtained by subtracting the two largest and two smallest values ​​from the obtained measurement points. It is essential that the measurement points are at least 10 mm apart.

[0065] The thickness of the body reinforcement structure is preferably 1.2 times or more, 1.5 times or more, or 2 times or more the average thickness of the main body.

[0066] Alternatively, by using FRP as the resin material of the body reinforcement structure, the rigidity of the body reinforcement structure can be improved in terms of material. In this case, the resin material of the main body does not have to be FRP, or the material of the main body and the body reinforcement structure may be FRP. Of course, the material of the main body, the body reinforcement structure, and the mounting part may all be FRP. For example, if the resin material of the body reinforcement structure is FRP made of PP and GF, the thickness of the body reinforcement structure only needs to be 2 mm or more. In this case, the thickness of the body reinforcement structure only needs to be equal to or greater than the average thickness of the main body, and may even be the same as the thickness of the main body.

[0067] When the thickness of the body reinforcement structure is greater than the average thickness of the main body, the surface of the body reinforcement structure protrudes relative to the surface of the main body. The protruding direction of this body reinforcement structure may be in any direction. For example, the body reinforcement structure may protrude toward the outside of the main body, or toward the inside of the storage space in the main body. When the body reinforcement structure protrudes toward the inside of the storage space, the body reinforcement structure may also serve as a partition plate for the storage space. Taking these into consideration, the shape of the body reinforcement structure can be at least one selected from the group consisting of a rib shape, a standing wall shape, and a partition plate shape.

[0068] The body reinforcement structure is provided in at least a part of the reinforced region of the main body, i.e., the region of the main body that extends from one of the pair of mounting parts to the other. The reinforced region can be defined as a region that is centered on a line connecting the pair of mounting parts and is within a distance of 10 mm from the line.

[0069] When the two body parts to which the pair of mounting parts are attached are spaced apart in the vehicle travel direction, the vehicle storage structure of the present invention can be said to reinforce the discontinuous part of the body in the vehicle travel direction. In this case, the reinforced region of the main body part that spans the two mounting parts extends in the vehicle travel direction. In this case, it is preferable that the body reinforcement structure also extends in the vehicle traveling direction, and it is more preferable that one end of the body reinforcement structure extends to one of the mounting portions, and it is particularly preferable that the other end of the body reinforcement structure extends to the other mounting portion.

[0070] When the two body portions to which the pair of mounting portions are attached are spaced apart in the vehicle width direction, the vehicle storage structure of the present invention can be said to reinforce a portion of the body that is discontinuous in the vehicle width direction. In this case, the reinforced region of the main body portion that spans the two mounting portions extends in the vehicle width direction. In this case, it is preferable that the body reinforcement structure also extends in the vehicle width direction. In this case, it is more preferable that one end of the body reinforcement structure extends to one of the mounting portions, and it is particularly preferable that the other end of the body reinforcement structure extends to the other mounting portion.

[0071] When the two body portions to which the pair of mounting portions are attached are spaced apart in the vehicle travel direction and the vehicle width direction, the vehicle storage structure of the present invention can be said to reinforce the discontinuous portion of the body in the vehicle travel direction and the vehicle width direction. In this case, the reinforced region of the main body portion that spans the two mounting portions extends in the vehicle travel direction and the vehicle width direction. In this case, it is preferable that the body reinforcement structure also extends in the vehicle travel direction and the vehicle width direction. In this case, it is more preferable that one end of the body reinforcement structure extends to one of the mounting parts, and it is particularly preferable that the other end of the body reinforcement structure extends to the other mounting part.

[0072] As described above, the vehicle storage structure of the present invention may have multiple pairs of mounting portions. When the vehicle storage structure of the present invention has multiple pairs of mounting portions, the main body has multiple reinforcing regions corresponding to the multiple pairs of mounting portions. In this case, it is preferable that the vehicle storage structure of the present invention has multiple body reinforcing structures corresponding to the multiple pairs of mounting portions and the multiple reinforcing regions.

[0073] When the vehicle storage structure of the present invention has multiple body reinforcement structural parts, each body reinforcement structural part may be separated from the other, but from the viewpoint of improving the rigidity of the vehicle storage structure of the present invention, it is preferable that each body reinforcement structural part is integrated.

[0074] For example, if the body reinforcement structures extend in directions that intersect with each other, it is preferable to directly integrate the body reinforcement structures with each other. Alternatively, if it is difficult to directly integrate the body reinforcement structures with each other, such as if the body reinforcement structures extend in directions that do not intersect with each other, the body reinforcement structures may be integrated with each other via ribs or the like.

[0075] Hereinafter, the vehicle storage structure of the present invention will be described with reference to specific examples.

[0076] Example 1 The vehicle storage structure of the first embodiment is attached to the side members and front inside panels that are body parts.

[0077] Fig. 1 is an explanatory diagram that schematically explains the relationship between the vehicle storage structure of Example 1 and the body member to which the vehicle storage structure of Example 1 is attached. Fig. 2 is an explanatory diagram that schematically explains the body member and the vehicle storage structure of Example 1 as viewed from diagonally forward. Fig. 3 is an explanatory diagram that schematically explains the body member and the vehicle storage structure of Example 1 as viewed from above. Fig. 4 is an explanatory diagram that schematically explains the body member and the vehicle storage structure of Example 1 as viewed from below.

[0078] Hereinafter, the terms "front," "rear," "left," "right," "up," and "down" refer to the front, rear, left, right, top, and bottom directions shown in the drawings. Note that the "front-rear direction" refers to the front-rear direction in the direction of vehicle travel, and the "left-right direction" refers to the width direction of the vehicle.

[0079] The vehicle storage structure 1 of the first embodiment includes a main body 2, four pairs of mounting portions 3, and two body reinforcing structural portions 4. The main body 2 is made of a resin material, specifically FRP containing PP as a resin and GF as an additive. The resin material contains only PP, and the blending ratio of PP to GF is 50:50 by mass.

[0080] As shown in FIGS. 1 and 2, the main body 2 has a shallow box shape that opens upward, and a storage space 20 is formed inside the main body 2.

[0081] The opening peripheral edge of the main body 2 forms a flange 22 that extends radially outward and surrounds the entire periphery of the opening 21. The flange 22 is a part of the main body 2 and is integrally formed with the peripheral wall 2S of the main body 2.

[0082] A number of ribs 23 that protrude radially outward and extend vertically are provided on the peripheral wall 2S of the main body 2 below the flange 22. The ribs 23 function as reinforcing parts that reinforce the peripheral wall 2S and, in turn, the main body 2. The ribs 23 protrude radially outward from the main body, extend vertically, and are arranged along the circumferential direction of the main body 2.

[0083] A front portion of the bottom wall 2B of the main body 2 and a rear portion of the flange 22 of the main body 2 are each provided with a through-hole that penetrates vertically.

[0084] The bottom wall 2B has two through holes spaced apart in the vehicle width direction. One of the through holes located on the left side of the bottom wall 2B is referred to as a first front mounting portion 31F, and the other located on the right side is referred to as a second front mounting portion 32F.

[0085] There are four through holes provided in the flange 22, which are spaced apart from one another in the vehicle width direction. From left to right, the through holes in the flange 22 are referred to as a first rear mounting portion 31R, a second rear mounting portion 32R, a third rear mounting portion 33R, and a fourth rear mounting portion 34R.

[0086] The first front mounting portion 31F is attached to the left side member LSM, which is one of the body parts B, via unillustrated bolts. The second front mounting portion 32F is attached to the right side member RSM, which is another of the body parts B, via unillustrated bolts. The left side member LSM and the right side member RSM are attached to the bumper reinforcement BR by fastening bolts. The bumper reinforcement BR is one of the body parts B, and is located in front of the left side member LSM and the right side member RSM, extending in the left-right direction. Therefore, it can be said that the bumper reinforcement BR spans the front ends of the left side member LSM and the right side member RSM in the left-right direction.

[0087] The first rear mounting portion 31R and the second rear mounting portion 32R are each attached via unillustrated bolts to the left front inside panel LFP, which is another part of the body portion B. The third rear mounting portion 33R and the fourth rear mounting portion 34R are each attached via unillustrated bolts to the right front inside panel RFP, which is another part of the body portion B.

[0088] The vehicle storage structure 1 of Example 1 can be said to span the left side member LSM and the left front inside panel LFP in the body, with the first front mounting portion 31F attached to the left side member LSM and the first rear mounting portion 31R attached to the left front inside panel LFP. Furthermore, the vehicle storage structure 1 of Example 1 can also be said to span the left side member LSM and the left front inside panel LFP in the body, with the first front mounting portion 31F attached to the left side member LSM and the second rear mounting portion 32R attached to the left front inside panel LFP. Furthermore, the vehicle storage structure 1 of Example 1 can also be said to span the right side member RSM and the right front inside panel RFP in the body, with the second front mounting portion 32F attached to the right side member RSM and the third rear mounting portion 33R attached to the right front inside panel RFP. Furthermore, the vehicle storage structure 1 of Example 1 can also be said to span the right side member RSM and the right front inside panel RFP in the body, with the second front mounting portion 32F attached to the right side member RSM and the fourth rear mounting portion 34R attached to the right front inside panel RFP.

[0089] Therefore, the vehicle storage structure 1 of Example 1 can be said to have four pairs of mounting portions 3, namely, the first front mounting portion 31F and the first rear mounting portion 31R, the first front mounting portion 31F and the second rear mounting portion 32R, the second front mounting portion 32F and the third rear mounting portion 33R, and the second front mounting portion 32F and the fourth rear mounting portion 34R.

[0090] As shown in FIG. 3, the vehicle storage structure 1 of Example 1 has reinforcement regions 25 in the main body 2 between the first front mounting portion 31F and the first rear mounting portion 31R, between the first front mounting portion 31F and the second rear mounting portion 32R, between the second front mounting portion 32F and the third rear mounting portion 33R, and between the second front mounting portion 32F and the fourth rear mounting portion 34R. The reinforcement region 25 between the first front mounting portion 31F and the first rear mounting portion 31R is referred to as the first reinforcement region 25F, the reinforcement region 25 between the first front mounting portion 31F and the second rear mounting portion 32R is referred to as the second reinforcement region 25S, the reinforcement region 25 between the second front mounting portion 32F and the third rear mounting portion 33R is referred to as the third reinforcement region 25T, and the reinforcement region 25 between the second front mounting portion 32F and the fourth rear mounting portion 34R is referred to as the fourth reinforcement region 25FO.

[0091] The vehicle storage structure 1 of Example 1 has two body reinforcement structures 4 that protrude from the main body 2 toward the inside of the storage space 20. The two body reinforcement structures 4 each extend in the front-rear direction and are spaced apart in the left-right direction. Of the two body reinforcement structures 4, the one located on the left side is referred to as the second body reinforcement structure 42, and the one located on the right side is referred to as the third body reinforcement structure 43.

[0092] A rear portion of the second body reinforcement structure 42 is provided in the second reinforcement region 25S, and a rear portion of the third body reinforcement structure 43 is provided in the third reinforcement region 25T.

[0093] The protruding height, ie, thickness, of the second body reinforcement structure 42 and the third body reinforcement structure 43 gradually decreases from the front side to the rear side, but is greater than the average thickness of the main body 2 .

[0094] The width of the second body reinforcement structure 42 and the third body reinforcement structure 43 is approximately 2 mm near their respective protruding ends. The rear end of the second body reinforcement structure 42 is connected to the second rear mounting portion 32R, and the front end of the second body reinforcement structure 42 is connected to the front wall 2F, which is located on the front side of the peripheral walls 2S of the main body 2. The rear end of the third body reinforcement structure 43 is connected to the third rear mounting portion 33R, and the front end of the third body reinforcement structure 43 is connected to the front wall 2F of the main body 2.

[0095] As described above, in the vehicle storage structure 1 of Example 1, the peripheral wall 2S of the main body 2 is provided with a large number of ribs 23. Therefore, the peripheral wall 2S has sufficient rigidity and functions as a reinforcing structure for the body, similar to the second body reinforcing structure 42 and the third body reinforcing structure 43.

[0096] The left wall 2L located on the left side of the peripheral wall 2S is provided in the first reinforcement region 25F and is a first body reinforcement structure 41 having a standing wall shape. The right wall 2R located on the right side of the peripheral wall 2S is provided in the fourth reinforcement region 25FO and is a fourth body reinforcement structure 44 having a standing wall shape. In other words, the left wall 2L of the peripheral wall 2S is the first body reinforcement structure 41, which is one of the body reinforcement structures 4. The right wall 2R of the peripheral wall 2S is also the fourth body reinforcement structure 44, which is one of the body reinforcement structures 4.

[0097] The protruding height, ie, thickness, of the first body reinforcement structure 41 and the fourth body reinforcement structure 44 is much greater than the average thickness of the main body 2 .

[0098] The width of the first body reinforcement structure 41 and the fourth body reinforcement structure 44 is approximately 2 mm, including the rib 23. The rear end of the first body reinforcement structure 41 is connected to the first rear mounting portion 31R, and the front end of the first body reinforcement structure 41 is connected to the front wall 2F. The rear end of the fourth body reinforcement structure 44 is connected to the fourth rear mounting portion 34R, and the front end of the fourth body reinforcement structure 44 is connected to the front wall 2F.

[0099] The main body 2 in the storage structure for a vehicle 1 of the first embodiment is box-shaped with a storage space, and has many ribs 23 on its peripheral wall 2S, thereby exhibiting excellent rigidity.

[0100] Furthermore, the first front mounting portion 31F and the second front mounting portion 32F are through-holes formed directly in the bottom wall 2B of the main body portion 2, and the first rear mounting portion 31R, the second rear mounting portion 32R, the third rear mounting portion 33R, and the fourth rear mounting portion 34R are through-holes formed directly in the flange 22 of the main body portion 2. For this reason, it can be said that all of the four pairs of mounting portions 3 in the vehicle storage structure 1 of Example 1 are firmly integrated with the main body portion 2. Furthermore, since the four pairs of mounting portions 3 are located between the upper and lower ends of the main body portion 2 and between the front and rear ends of the main body portion 2, it can be said that the mounting portions 3 and the main body portion 2 are linearly arranged.

[0101] Furthermore, the first body reinforcement structure 41, the second body reinforcement structure 42, the third body reinforcement structure 43 and the fourth body reinforcement structure 44 are all vertically wall shaped and have excellent rigidity.

[0102] Through the above cooperation, the vehicle storage structure 1 of Example 1 fully reinforces the discontinuous portion of the body formed between the left side member LSM and the left front inside panel LFP, and also fully reinforces the discontinuous portion of the body formed between the right side member RSM and the right front inside panel RFP.

[0103] In the vehicle storage structure 1 of Example 1 mounted on a vehicle, the front wall 2F of the main body 2 is disposed at a position equivalent to the position where an upper cross member, which is a type of reinforcing structure, is mounted on a conventional vehicle. As described above, the front wall 2F has many ribs 23 and is highly rigid. Therefore, the vehicle storage structure 1 of Example 1 can also be said to have the upper cross member integral with the main body 2. Furthermore, in the vehicle storage structure 1 of Example 1 mounted on a vehicle, the left wall 2L and right wall 2R of the main body 2 are disposed at positions equivalent to those where the left and right upper sides, which are a type of reinforcing structure, are mounted in conventional vehicles. The left wall 2L and right wall 2R also have many ribs 23 and are highly rigid. Therefore, the vehicle storage structure 1 of Example 1 can also be said to have the left and right upper sides integral with the main body 2.

[0104] 4, the bottom wall 2B of the vehicle storage structure 1 of Example 1 is provided with a plurality of ribs 23 at the rear end and at a substantially central portion in the front-rear direction. Each rib 23 protrudes downward from the bottom wall 2B, extends in the front-rear direction, and is spaced apart in the left-right direction. Therefore, the main body 2 of the vehicle storage structure 1 of Example 1 is reinforced at the rear end and at a substantially central portion in the front-rear direction. In the vehicle storage structure 1 of Example 1 mounted on a vehicle, the approximate center in the front-rear direction of the bottom wall 2B of the main body 2 is located at a position equivalent to the position where a lower cross member, which is a type of reinforcing structure, is mounted in a conventional vehicle. Therefore, the vehicle storage structure 1 of Example 1 can also be said to have the lower cross member integral with the main body 2.

[0105] Example 2 Similar to the vehicle storage structure 1 of Example 1, the vehicle storage structure 1 of Example 2 is attached to the side members and front inside panel, which are body part B. The vehicle storage structure 1 of Example 2 is generally the same as the vehicle storage structure 1 of Example 1, except that it does not have the second body reinforcement structural part 42 and the third body reinforcement structural part 43, the first front mounting part 31F and the second front mounting part 32F are provided on the front wall 2F rather than the bottom wall 2B of the main body part 2, and the front wall 2F of the main body part 2 has an inverted U shape.

[0106] 5 is an explanatory diagram illustrating a schematic view of the vehicle storage structure 1 of the second embodiment as viewed obliquely from the front. The vehicle storage structure 1 of the second embodiment will be described below, focusing on the differences from the vehicle storage structure 1 of the first embodiment.

[0107] The flange 22 of the main body 2 in the vehicle storage structure 1 of Example 2 is formed with a first rear mounting portion 31R, a second rear mounting portion 32R, a third rear mounting portion 33R, and a fourth rear mounting portion 34R, which are similar to those of the vehicle storage structure 1 of Example 1.

[0108] The first rear mounting portion 31R and the second rear mounting portion 32R are attached to the left front inside panel LFP, and the third rear mounting portion 33R and the fourth rear mounting portion 34R are attached to the right front inside panel RFP. Therefore, the vehicle storage structure 1 of the first embodiment can be said to be bridged between the left front inside panel LFP, which is one of the body parts B, and the right front inside panel RFP, which is the other of the body parts B, by the first rear mounting portion 31R, the second rear mounting portion 32R, the third rear mounting portion 33R, and the fourth rear mounting portion 34R. In the vehicle storage structure 1 of Example 2, each of the first rear mounting portion 31R and the third rear mounting portion 33R, the first rear mounting portion 31R and the fourth rear mounting portion 34R, the second rear mounting portion 32R and the third rear mounting portion 33R, and the second rear mounting portion 32R and the fourth rear mounting portion 34R can essentially be referred to as a pair of mounting portions 3.

[0109] As shown in Fig. 4, a plurality of ribs 23 are provided at the rear end of the bottom wall 2B of the main body 2. Each rib 23 protrudes downward from the bottom wall 2B, extends in the front-to-rear direction, and is spaced apart in the left-to-right direction. The ribs 23 are provided in a reinforcement region 25 between the first rear mounting portion 31R and the third rear mounting portion 33R, a reinforcement region 25 between the first rear mounting portion 31R and the fourth rear mounting portion 34R, a reinforcement region 25 between the second front mounting portion 32F and the third rear mounting portion 33R, and a reinforcement region 25 between the second front mounting portion 32F and the fourth rear mounting portion 34R. Therefore, in the vehicle storage structure 1 of Example 2, it can be said that a body reinforcement structure 4 is provided in each of the reinforcement area 25 between the first rear mounting portion 31R and the third rear mounting portion 33R, the reinforcement area 25 between the first rear mounting portion 31R and the fourth rear mounting portion 34R, the reinforcement area 25 between the second front mounting portion 32F and the third rear mounting portion 33R, and the reinforcement area 25 between the second front mounting portion 32F and the fourth rear mounting portion 34R.

[0110] A plurality of ribs 23 arranged in a grid pattern are provided on the front wall 2F of the main body 2. The left and right ends of the front wall 2F each extend downward in a columnar shape.

[0111] The left and right ends of the front wall 2F are each formed with a through-hole (not shown). The through-hole formed at the left end of the front wall 2F is referred to as the first front mounting portion 31F, and the through-hole formed at the left end of the front wall 2F is referred to as the second front mounting portion 32F. The first front mounting portion 31F is attached to the left side member LSM, and the second front mounting portion 32F is attached to the right side member RSM. Therefore, the vehicle storage structure 1 of the second embodiment can be said to span between the left side member LSM, which is one of the body parts B, and the right side member RSM, which is the other of the body parts B, by the first front mounting portion 31F and the second front mounting portion 32F. In the vehicle storage structure 1 of the second embodiment, the first front mounting portion 31F and the second front mounting portion 32F can be referred to as a pair of mounting portions 3.

[0112] As described above, the front wall 2F is reinforced with a plurality of lattice-shaped ribs 23 and has excellent rigidity. The ribs 23 are provided in the reinforcement region 25 between the first front mounting portion 31F and the second front mounting portion 32F. Therefore, in the vehicle storage structure 1 of the second embodiment, it can be said that the body reinforcement structure 4 is provided in the reinforcement region 25 between the first front mounting portion 31F and the second front mounting portion 32F.

[0113] The vehicle storage structure 1 of Example 2 can be said to span between the left front inside panel LFP, which is one of the body parts B, and the right front inside panel RFP, which is another of the body parts B, and also span between the left side member LSM, which is another of the body parts B, and the right side member RSM, which is another of the body parts B.

[0114] The vehicle storage structure 1 of the second embodiment fully reinforces the discontinuous portion of the body formed between the left side member LSM and the right side member RSM, and also fully reinforces the discontinuous portion of the body formed between the left front inside panel LFP and the right front inside panel RFP.

[0115] In the vehicle storage structure 1 of Example 2 mounted on a vehicle, the front wall 2F of the main body 2 is disposed at a position equivalent to the position where a front face, which is a type of reinforcing structure, is mounted on a conventional vehicle. Therefore, the vehicle storage structure 1 of Example 2 can also be said to have the front face integral with the main body 2.

[0116] Example 3 Similar to the vehicle storage structure 1 of Example 1, the vehicle storage structure 1 of Example 3 is attached to the side members and front inside panel, which are body part B. The vehicle storage structure 1 of Example 3 is generally the same as the vehicle storage structure 1 of Example 1, except that the second body reinforcement structural part 42 and the third body reinforcement structural part 43 extend in an oblique direction.

[0117] Fig. 6 is an explanatory diagram illustrating a schematic view of the vehicle storage structure 1 of Example 3 as viewed obliquely from the front, and Fig. 7 is an explanatory diagram illustrating a schematic view of the vehicle storage structure 1 of Example 3 as viewed from above. The vehicle storage structure 1 of Example 3 will be described below, focusing on the differences from the vehicle storage structure 1 of Example 1.

[0118] In the vehicle storage structure 1 of Example 3, the second body reinforcement structure 42 extends from the first front mounting portion 31F toward the second rear mounting portion 32R, from the front and left side toward the rear and right side. The third body reinforcement structure 43 extends from the second front mounting portion 32F toward the third rear mounting portion 33R, from the front and right side toward the rear and left side.

[0119] Therefore, in the vehicle storage structure 1 of Example 3, the entire second body reinforcement structure 42 is provided in the second reinforcement region 25S, and the entire third body reinforcement structure 43 is provided in the third reinforcement region 25T.

[0120] The vehicle storage structure 1 of the third embodiment, like the vehicle storage structure 1 of the first embodiment, fully reinforces the discontinuous portion of the body formed between the left side member LSM and the left front inside panel LFP, and also fully reinforces the discontinuous portion of the body formed between the right side member RSM and the right front inside panel RFP.

[0121] Furthermore, since the entire second body reinforcement structure 42 is provided in the second reinforcement region 25S and the entire third body reinforcement structure 43 is provided in the third reinforcement region 25T, the vehicle storage structure 1 of Example 3 can be said to more fully reinforce the discontinuous portion of the body formed between the left side member LSM and the left front inside panel LFP, and also to more fully reinforce the discontinuous portion of the body formed between the right side member RSM and the right front inside panel RFP.

[0122] In the vehicle storage structure 1 of Example 3, the second body reinforcement structural portion 42 and the third body reinforcement structural portion 43 each extend in an oblique direction. In other words, the second body reinforcement structural portion 42 and the third body reinforcement structural portion 43 each extend in the vehicle width direction and the vehicle traveling direction. Therefore, the second body reinforcement structural portion 42 and the third body reinforcement structural portion 43 in the vehicle storage structure 1 of Example 3 also have the advantage of being able to more efficiently reinforce the discontinuous portions in the body described above.

[0123] Although the present invention has been described above, the present invention is not limited to the above-described embodiments, etc., and it is possible to implement the present invention by appropriately extracting and combining elements described in the embodiments, etc., and to make various modifications within the scope that does not deviate from the spirit of the present invention.
