Description

Technical Field

[0001] The present invention relates to a vehicle storage box which is laid on a trunk floor of a vehicle. Background Art

[0002] The trunk floor (e.g. luggage room) of a passenger car or other vehicle stores spare tires, other spare parts (tools, triangular display panels, etc.), and various luggage of the user. Therefore, a vehicle storage box for storing various spare parts and luggage of the user (hereinafter referred to as storage items) is laid on the vehicle panel constituting the trunk floor. The vehicle storage box is required to have the usability and rigidity required to function as a storage box. In addition, the vehicle storage box preferably has a high design of the surface facing the interior of the vehicle. Moreover, the vehicle storage box is sometimes required to have the function of suppressing the sound and heat transmitted from the outside of the vehicle to the inside of the vehicle.

[0003] For example, Patent Document 1 describes a luggage storage mechanism having three storage boxes that are combined and laid on the entire trunk floor of a vehicle. Patent Documents 2 and 3 describe materials and manufacturing methods for highly designed vehicle interior parts laid on the trunk floor of a vehicle.

[0009] Problems to be solved by the invention

[0010] In order to function as a storage box, a vehicle storage box needs a partition for dividing the storage area and holding the stored items. For example, if a sheet-like fiber material (felt, etc.), a bead foam (so-called expanded polystyrene), etc. is used, a vehicle storage box including a partition can also be formed in one piece. However, the fiber material is not strong enough as a partition, so it is necessary to use a hard resin or other component to add a separate partition member. The separate partition member has the advantage of being able to change the division of the storage area, but it requires additional processing costs for assembling the partition member to the vehicle storage box.

[0011] In addition, if the partition is a hard member, when the storage object contacts the partition due to the vibration of the vehicle, it is also possible to generate abnormal noise or damage the storage object. The bead foam is lightweight and has cushioning properties, so the possibility of generating abnormal noise and damaging the storage object is low. However, the vehicle storage box using the bead foam needs to be formed thicker in order to obtain the required strength, so the storage volume is reduced.

[0012] Furthermore, as described above, the vehicle storage box preferably has a high design property on the surface facing the interior of the vehicle. In order to improve the design property, for example, it is conceivable to form the vehicle storage box using a sheet-like surface material composed of a synthetic resin or the like.

[0013] However, it is not possible to obtain a partition having the required strength only by using the surface material, so in this case, it is also necessary to use a hard resin or other member to add a separate partition component. If a partition component using a hard member is provided, a member made of a material different from the surface material is arranged in the vehicle storage box, so the sense of unity disappears, thereby reducing the design. On the other hand, if the storage area is not divided by a partition component, the storage items cannot be held, so the usability of the vehicle storage box is reduced.

[0014] Patent Document 1 does not propose a luggage storage mechanism (vehicle storage box) using a skin material. Patent Documents 2 and 3 propose vehicle interior parts having a skin material (skin layer), but do not show the shape or structure of the vehicle storage box.

[0015] The present invention has been made to solve the above-mentioned problems in the background art, and an object of the present invention is to provide a vehicle storage box that does not require additional parts and has high designability.

[0016] Means for solving problems

[0017] In order to achieve the above-mentioned purpose, the vehicle storage box of the present invention is a vehicle storage box laid on the trunk floor, the vehicle storage box has a storage portion surrounded by a bottom surface and a wall portion rising from the bottom surface above the vehicle, the storage portion has a partition portion convexly protruding from the bottom surface above the vehicle, the bottom surface, the wall portion and the partition portion are integrally formed by laminating a base material composed of a resin sheet and a surface material, and the surface material faces the interior of the vehicle.

[0024] Next, the present invention will be described using the drawings.

[0025] Figure 1 It is a perspective view showing a structural example of a vehicle storage box according to the present invention. Figure 2 yes Figure 1 A side sectional view of a storage box for a vehicle is shown. Figure 3 It means in Figure 1 and Figure 2 sectional view of an example of a sheet member used in manufacturing a vehicle storage box shown in FIG. Figure 4 It means by Figure 1 and Figure 2 A side cross-sectional view of an example of a storage recess formed in a partition portion of a vehicle storage box shown.

[0026] Figure 2 and Figure 4 Schematically shows the equivalent Figure 1 The cross section of the vehicle storage box is shown when it is cut along the position of the AA line. Figure 1 The FRONT, REAR, LEFT, RIGHT, UP, and DOWN shown in the figure represent the front, rear, left, right, top, and bottom of the vehicle, respectively. The left-right positional relationship is based on the direction in which the vehicle is viewed from the front. Figure 2 and Figure 4 The FRONT, REAR, UP, and DOWN shown also indicate the front, rear, top, and bottom of the vehicle. Figure 1~Figure 4 The components of the present invention are schematically shown, and the size, shape, structure, position, etc. of each component are not accurately shown.

[0027] like Figure 1 and Figure 2As shown, the vehicle storage box 1 of the present invention has the following structure: it has a storage portion 2 surrounded by a bottom surface 21 and a wall portion 22 rising from the bottom surface 21 toward the upper side of the vehicle, and the storage portion 2 is provided with a partition portion 3 convexly protruding from the bottom surface 21 toward the upper side of the vehicle. As described above, the partition portion 3 is used to divide the storage area in the storage portion 2 and hold the stored items. Figure 1 and Figure 2 The vehicle storage box 1 of the present invention shown in the figure is a structure in which the bottom surface 21, the wall portion 22 and the partition portion 3 are integrally formed using a resin sheet member. The vehicle storage box 1 is arranged on a trunk floor provided behind a seat (eg, a rear seat) of a vehicle.

[0028] In this way, by integrally forming the partition 3 and the like using a resin sheet member, a separate partition component is not required, and additional processing costs for assembling the partition component to the vehicle storage box 1 are not required. In addition, by providing the partition 3, the storage items can be held, and the usability as a storage box is not reduced. Moreover, by integrally forming the vehicle storage box 1, compared with a structure having a plurality of storage boxes, the gaps between the storage boxes disappear, thereby suppressing the leakage of sound and heat from the outside of the vehicle to the inside of the vehicle.

[0029] like Figure 3 As shown, the sheet member used in the manufacture of the vehicle storage box 1 is a structure in which a base material 11 composed of a resin sheet, a skin material 12, and a non-woven fabric 13 arranged on the side opposite to the skin material 12 across the base material 11 are stacked. The vehicle storage box 1 is formed in a manner in which the skin material 12 faces the interior of the vehicle. The base material 11 is, for example, a sheet composed of PP (polypropylene). The skin material 12 is, for example, a non-woven fabric such as a flat needle punch or a velvet needle punch composed of synthetic resin fibers. The skin material 12 may also be natural leather, synthetic leather, etc. The non-woven fabric 13 may also be absent.

[0030] The vehicle storage box 1 of the present invention is a structure formed by a relatively thin sheet member formed by stacking a base material 11, a skin material 12 and a non-woven fabric 13, so it does not need to be formed thickly like a bead foam, and the storage volume will not be reduced. In addition, the skin material 12 facing the interior of the vehicle has a high-grade feel compared to hard resin materials and bead foams, and is integrally formed including the partition 3, so that a vehicle storage box 1 with a high sense of design and a sense of unity can be obtained. In addition, the skin material 12 has a sound absorbing effect and a heat insulating effect, so the sound and heat transmitted from the outside of the vehicle to the inside of the vehicle are suppressed.

[0031] Moreover, the resin substrate 11 has a higher hardness by molding, so that the storage portion 2 including the partition 3 having the strength required to function as a storage box can be obtained. On the other hand, the substrate 11 is easier to deform than a hard resin, so a partition 3 with cushioning properties can be obtained. In addition, since the skin material 12 is stacked on the substrate 11 facing the interior of the vehicle, the abnormal noise generated when the storage object abuts against the partition 3 is reduced, and the possibility of damage to the storage object is also reduced.

[0032] like Figure 4 As shown, the storage section 2 is a structure including at least two storage recesses 4 that serve as a storage area for stored objects and are formed by at least one partition 3. The partition 3 is formed along the width direction (left-right direction) of the vehicle. Figure 4 An example of a vehicle storage box 1 is shown in which three receiving recesses 4 (a first receiving recess 41, a second receiving recess 42, and a third receiving recess 43) are provided in the front-rear direction of the vehicle by two partitions 3 formed along the width direction of the vehicle. Figure 1 The housing recess 4 shown in the figure is further formed along the front-rear direction of the vehicle, so that the one housing recess 4 is divided into a plurality of housing recesses 4 .

[0033] In the present invention, among the plurality of receiving recesses 4, the receiving recess 4 located closest to the front of the vehicle (in Figure 4 The bottom surface 21 of the third receiving recess 43 is connected to the receiving recess 4 (in the rear of the vehicle) Figure 4 That is, in the vehicle storage box 1 of the present invention, the storage recess 4 located closest to the rear of the vehicle is formed to be the deepest, and the storage recess 4 located closest to the front of the vehicle is formed to be the shallowest, and a plurality of storage recesses 4 are formed in a manner that gradually becomes shallower from the rear of the vehicle toward the front of the vehicle.

[0034] Generally, in the trunk floor, at the rear of the vehicle, even if the receiving recess 4 is deep, it is easy to visually confirm the stored items, but at the front of the vehicle, if the receiving recess 4 is deep, it is difficult to visually confirm the stored items. Figure 4 As shown, since the storage recess 4 (third storage recess 43) at the front of the vehicle is formed shallowest, the storage items stored in the storage recess 4 are easily visually confirmed and taken out. Therefore, the usability of the vehicle storage box 1 is improved.

[0035] In addition, for example, when the vehicle is rear-ended by another vehicle from the rear, the third storage recess 43 formed shallowly in the front of the vehicle will be blocked by the seat back even if the storage items are scattered forward, so the possibility of collision with the occupants is low. On the other hand, if the first storage recess 41 at the rear of the vehicle is shallow, the storage items scattered forward may pass over the seat back and reach the passenger compartment, colliding with the occupants. Therefore, by forming a plurality of storage recesses 4 in a manner that gradually becomes shallower from the rear of the vehicle toward the front of the vehicle, the visibility and accessibility of the stored storage items can be improved, and the possibility of collision between the storage items and the occupants in the event of a rear-end collision can be reduced.

[0036] Furthermore, in the case of being rear-ended by another vehicle from the rear, the impact of the rear-end collision is directly transmitted to the seat via the vehicle storage box 1 for a structure having a split partition member and a plurality of receiving recesses 4 having the same depth at the rear and front of the vehicle. In this case, the occupant of the seat may suffer from injuries such as cervical sprain (so-called cervical hyperflexion sprain). The vehicle storage box 1 of the present invention absorbs the energy of the rear-end collision by having a plurality of receiving recesses 4 of different depths arranged in the front-rear direction of the vehicle and a partition 3 formed in a convex shape along the width direction of the vehicle, thereby reducing the impact of the rear-end collision transmitted to the seat via the vehicle storage box 1.

[0037] It should be noted that it is also possible to Figure 4 The shallower receiving recess 4 (in Figure 4 Electronic devices such as batteries, motors, converters, and inverters are arranged under the vehicle (the third receiving recess 43, or the second receiving recess 42 and the third receiving recess 43). In this way, even if electronic devices are arranged under the vehicle in the receiving recess 4, the sound absorption effect of the surface material 12 can suppress the leakage of abnormal noises generated by electronic devices such as motors, converters, and inverters into the vehicle. At this time, the electromagnetic waves generated by the electronic devices can also be shielded by mixing electromagnetic wave shielding materials into the surface material 12, the base material 11, and the non-woven fabric 13. In this case, the influence of electromagnetic waves generated by the electronic devices under the vehicle on mobile phones, medical equipment, etc. used in the vehicle interior can be reduced. The electronic device can also be arranged in the deepest receiving recess 4 among the multiple receiving recesses 4 (in Figure 4 The middle is the lower part of the vehicle where the first receiving recess 41 is located.

[0038] The vehicle storage box 1 of the present invention comprises a storage portion 2 surrounded by a bottom surface 21 and a wall portion 22 rising from the bottom surface 21 toward the upper side of the vehicle, and the storage portion 2 is provided with a partition portion 3 protruding from the bottom surface 21 toward the upper side of the vehicle, and the bottom surface 21, the wall portion 22 and the partition portion 3 are integrally formed using a sheet member made of resin. Therefore, additional components such as partition components are not required.

[0039] In addition, the resin sheet member used in the manufacture of the vehicle storage box 1 of the present invention is a structure in which a base material 11 composed of a resin sheet and a skin material 12 are stacked, and the skin material 12 is arranged facing the interior of the vehicle. The skin material 12 facing the interior of the vehicle has a high-grade feel compared to a hard resin material or a bead foam, and is integrally formed including the partition 3, thereby not including parts of different materials, so that a vehicle storage box 1 with a sense of unity and high design can be obtained. Therefore, according to the present invention, a vehicle storage box 1 with high design that does not require additional parts can be obtained.
