Description

[Technical Field]

[0001] The present invention relates to a vehicle storage device capable of wirelessly feeding power to an electronic device stored in a storage section. [Background technology]

[0002] A conventional vehicle storage device of this type is, for example, a wireless power feeder disclosed in Patent Document 1. This wireless power feeder includes a holder case shaped like a rectangular box with a bottom, and an electromagnetic induction type power feeder attached to the outer surface of the rear wall of the holder case. The wireless power feeder wirelessly feeds power to an electronic device such as a smartphone stored in the holder case via the power feeder.

[0003] With the aim of popularizing wireless power transfer, the Wireless Power Consortium (WPC) was established as a standardization organization for contactless power transfer methods, primarily based on electromagnetic induction. The WPC established the international standard, Qi (pronounced "chee"). Wireless power transfer based on the Qi standard utilizes electromagnetic induction between a transmitting coil and a receiving coil. In order to display the Qi standard logo on a product, it is necessary to obtain Qi certification from the WPC.

[0004] When obtaining Qi certification for the wireless power supply device described above, it is necessary to obtain Qi certification for the entire holder case and for the power supply unit. In this case, if there are multiple types of holder cases, it is necessary to obtain Qi certification for each of the holder cases. Therefore, the following measures can be considered to reduce the number of components that require Qi certification.

[0005] That is, first, the common resin panel is Qi-certified. Then, an opening is formed in a part of the side wall of the holder case corresponding to the power supply device, and the opening is closed by fitting the above-mentioned Qi-certified resin panel made of a separate material. In this way, even if there are multiple types of holder cases, simply by forming an opening for fitting the Qi-certified resin panel in a part of the side wall of the holder case corresponding to the power supply device, it is not necessary to obtain Qi certification for each type of holder case.

[0006] [Patent Document 1] Japanese Patent Application Publication No. 2022-13299 Summary of the Invention [Problem to be solved by the invention]

[0007] However, fitting a Qi-certified resin panel into a portion of the side wall of the holder case that corresponds to the power supply device as described above poses the following problem: A gap is formed between the periphery of the opening in the side wall of the holder case and the periphery of the resin panel, which may allow liquids such as water to enter the power supply device through the gap.

[0008] In addition, gaps are formed between the power supply device and the resin panel and between the power supply device and the side wall of the holder case. Therefore, vibrations generated during vehicle operation may cause the power supply device to repeatedly hit the resin panel or the side wall of the holder case, causing abnormal noise. Therefore, a vehicle storage device that can prevent liquid from entering the power supply device and the generation of abnormal noise is desired. [Means for solving the problem]

[0009] Various aspects of the vehicle storage device for solving the above problems will be described below. [Embodiment 1] A vehicle storage device comprising: a storage section having a side wall with a power supply opening formed therein and for storing an electronic device inside the side wall; a resin panel that is fitted into the power supply opening to cover the power supply opening; and a wireless power supply that wirelessly supplies power to the electronic device from outside the side wall through the resin panel, wherein a laminate is disposed between the side wall side surface of the wireless power supply device and the side wall and the resin panel, and the laminate comprises an adhesive layer, a resin layer laminated on the adhesive layer, and a flexible cushion layer laminated on the surface of the resin layer opposite the adhesive layer side.

[0010] Generally, the resin layer has a function of impermeable to liquids, and the cushion layer has a function of absorbing shocks and vibrations. According to the above configuration, a laminate is disposed between the side wall surface of the wireless power supply device and the side wall and resin panel. Therefore, when a liquid such as water is splashed onto the housing, the resin layer in the laminate can prevent the liquid from penetrating from the inside of the side wall through the gap at the boundary between the resin panel and the side wall to the wireless power supply device located outside the side wall. Additionally, the cushion layer in the laminate absorbs vibrations of the wireless power supply device caused by vibrations generated during vehicle operation, etc. This can prevent the wireless power supply device from repeatedly hitting the side wall and resin panel while vibrating, thereby preventing abnormal noise. Therefore, liquid penetration into the wireless power supply device and the generation of abnormal noise can be prevented.

[0011] [Aspect 2] The vehicle storage device described in [Aspect 1] is characterized in that the laminate extends around the wireless power supply device to the surface of the wireless power supply device opposite the surface facing the side wall.

[0012] According to the above configuration, the laminate can be interposed between the surface of the wireless power feeder opposite the side wall surface and another component close to that surface, and therefore, the cushion layer of the laminate can suppress abnormal noise that would occur when the surface of the wireless power feeder opposite the side wall surface hits another component close to that surface due to vibrations generated during vehicle operation, etc.

[0013] [Aspect 3] A vehicle storage device as described in [Aspect 1] or [Aspect 2], characterized in that it is provided with a cover member that contacts the upper end of the side wall and covers the wireless power supply device from above, and the laminate is arranged so as to cover the boundary portion between the cover member and the side wall.

[0014] According to the above configuration, the laminate covers the boundary between the cover member and the side wall, and therefore, when a liquid such as water is splashed onto the housing, the resin layer in the laminate can prevent the liquid from entering from the inside of the side wall through the gap at the boundary between the cover member and the side wall to the wireless power supply device located outside the side wall.

[0015] [Aspect 4] A vehicle storage device described in any one of [Aspect 1] to [Aspect 3], characterized in that the wireless power supply device comprises a bottomed box-shaped case having an opening on the side wall side, and a lid fitted into the case so as to cover the opening, and the laminate is arranged so as to cover the boundary portion between the case and the lid.

[0016] According to the above configuration, the laminate covers the boundary between the case and the lid, and therefore, if a liquid such as water enters the wireless power supply device from the side wall, the resin layer in the laminate can prevent the liquid from entering the interior of the wireless power supply device through the gap at the boundary between the case and the lid.

[0017] [Aspect 5] A vehicle storage device according to any one of [Aspect 1] to [Aspect 4], characterized in that the resin layer is made of a polyethylene terephthalate film, the cushion layer is made of a nonwoven fabric, and the adhesive layer is made of a double-sided adhesive tape.

[0018] According to the above configuration, by forming the resin layer using a polyethylene terephthalate film, the resin layer melts and becomes thinner when welded to the cushion layer. By forming the cushion layer using a nonwoven fabric, the cushion layer can be made thinner than when the cushion layer is formed using rubber, urethane foam, or the like. This contributes to a thinner laminate, which in turn contributes to space saving. In addition, by forming the adhesive layer using a double-sided adhesive tape, the laminate can be more easily adhered to a desired position than when the adhesive layer is formed using an adhesive. [Effects of the Invention]

[0019] The present invention has the effect of suppressing the intrusion of liquid into the wireless power feeder and the generation of abnormal noise. [Brief explanation of the drawings]

[0020] [Figure 1] 1 is a perspective view of a vehicle storage device according to an embodiment; [Figure 2] FIG. 2 is an enlarged cross-sectional view taken along line 2-2 of FIG. [Figure 3] FIG. 3 is an enlarged view of a main part of FIG. 2. [Figure 4] FIG. 2 is an enlarged schematic cross-sectional view showing a part of the laminate. DETAILED DESCRIPTION OF THE INVENTION

[0021] An embodiment of a vehicle storage device will be described below with reference to the drawings. In the following description, the forward direction of the vehicle will be referred to as the front, and the backward direction will be referred to as the rear. Furthermore, the vertical direction will refer to the vertical direction of the vehicle, and the vehicle width direction will refer to the left and right direction of the vehicle.

[0022] <Vehicle storage device 11> 1 and 2, the vehicle accommodation device 11 is provided so as to be incorporated into a center console disposed between the driver's seat and the passenger seat in the vehicle cabin, for example. The vehicle accommodation device 11 includes a storage section 12, a resin panel 13, a wireless power feeder 14, a cover member 15, and a laminated body 16.

[0023] <Containment Unit 12> The storage compartment 12 is made of resin and has a rectangular box shape with a bottom that is open at the top and extends in the front-to-rear direction. That is, the storage compartment 12 has a bottom wall 17, a front wall 18, a rear wall 19, a left wall 20, and a right wall 21 as an example of a side wall. A rectangular plate-shaped electronic device 22, such as a smartphone, is stored in the space inside the bottom wall 17, the front wall 18, the rear wall 19, the left wall 20, and the right wall 21, i.e., inside the storage compartment 12. The electronic device 22 is compatible with wireless power supply.

[0024] A rectangular power feed opening 23 is formed in the center of right wall 21. That is, right wall 21 has power feed opening 23 in the center. A rectangular resin panel 13 is fitted into power feed opening 23. That is, power feed opening 23 is closed by resin panel 13. Right wall 21 and resin panel 13 have the same thickness. A first thin-wall portion 24 that halves the thickness is formed around the periphery of power feed opening 23 in right wall 21.

[0025] A second thin-walled portion 25, which is half the thickness of the resin panel 13, is formed on the periphery of the resin panel 13. The first thin-walled portion 24 and the second thin-walled portion 25 correspond to each other. When the resin panel 13 is fitted into the power supply opening 23, the first thin-walled portion 24 and the second thin-walled portion 25 overlap each other. The storage section 12 is positioned with an inclination of approximately 20° to the right. Therefore, when the electronic device 22 is stored in the storage section 12 and leaned against the center of the right wall 21, this position is maintained by gravity. That is, in this case, gravity maintains one surface of the electronic device 22 in contact with the inner surface of the right wall 21 and the inner surface of the resin panel 13.

[0026] <Wireless power supply 14> 1 and 2, the wireless power feeder 14 is disposed on the right side of the center of the right wall 21. That is, the wireless power feeder 14 is disposed on the right side of the plastic panel 13. The wireless power feeder 14 wirelessly feeds power to the electronic device 22 accommodated inside the right wall 21 from the right side (outside) of the right wall 21 through the plastic panel 13 by electromagnetic induction. That is, the wireless power feeder 14 feeds power to the electronic device 22 by utilizing electromagnetic induction between its transmitting coil (not shown) and a receiving coil (not shown) of the electronic device 22.

[0027] The wireless power supply device 14 includes a bottomed box-shaped case 27 having an opening 26 on the right wall 21 side, a rectangular plate-shaped lid 28 fitted into the case 27 so as to close the opening 26, and a power supply device main body 29 housed in the case 27. The power supply device main body 29 includes the above-mentioned transmission coil (not shown) and the like. The case 27 is made of metal such as aluminum. The lid 28 is made of resin. The lid 28 is larger than the resin panel 13.

[0028] A support plate 30 is disposed on the right side of the wireless power feeder 14. A bent portion 31 is provided at the upper end of the support plate 30, which is bent in a generally L-shape so as to protrude to the left side, which is the wireless power feeder 14 side. The height of the upper end of the wireless power feeder 14 is slightly lower than the height of the upper end of the support plate 30 and slightly higher than the height of the upper end of the right wall 21 of the housing section 12.

[0029] <Cover member 15> 1 to 3, cover member 15 is made of resin. Cover member 15 extends in the front-rear direction and has a generally inverted U-shape in cross section. Cover member 15 has an upper wall 32, a plate-shaped left extension portion 33 extending downward from the left end of upper wall 32, and a plate-shaped right extension portion 34 extending downward from the right end of upper wall 32. Cover member 15 is arranged to cover wireless power feeder 14 from above.

[0030] The cover member 15 is fixed in place with the lower end of the left extension 33 in contact with the upper end of the right wall 21 of the storage section 12 and the right extension 34 engaged with the bent portion 31 of the support plate 30. The right surface of the left extension 33 and the outer surface (right surface) of the right wall 21 are flush with each other. The upper wall 32 of the cover member 15 is located slightly higher than the upper end of the support plate 30. In other words, a gap is formed between the upper wall 32 of the cover member 15 and the upper end of the support plate 30.

[0031] <Laminate 16> 2 to 4, laminate 16 is in the form of a thin sheet. Laminate 16 is disposed on the surface of wireless power feeder 14 on the side of right wall 21, and between right wall 21 and resin panel 13. Laminate 16 has a three-layer structure. That is, laminate 16 includes an adhesive layer 35, a resin layer 36 laminated on adhesive layer 35, and a flexible cushion layer 37 laminated on the surface of resin layer 36 opposite to the adhesive layer 35 side. In laminate 16, resin layer 36 has a function of preventing the penetration of liquids such as water, and cushion layer 37 has a function of absorbing shocks and vibrations.

[0032] In this example, the resin layer 36 is made of a polyethylene terephthalate film. In this example, the cushion layer 37 is made of a nonwoven fabric. In this example, the adhesive layer 35 is made of an acrylic double-sided adhesive tape. The resin layer 36 is welded to the cushion layer 37. One surface of the adhesive layer 35 is adhered to the surface of the resin layer 36 opposite to the cushion layer 37 side.

[0033] The laminate 16 is adhered to the wireless power feeder 14 by an adhesive layer 35 while covering the entire surface of the wireless power feeder 14 facing the right wall 21. Therefore, the laminate 16 is arranged so as to cover a boundary portion 38 between the case 27 and the lid 28 of the wireless power feeder 14. The lower end portion of the laminate 16 is bent so as to cover a portion of the lower surface of the wireless power feeder 14. The upper end portion of the laminate 16 wraps around the upper surface of the wireless power feeder 14 and extends to the surface of the wireless power feeder 14 opposite the surface facing the right wall 21. The upper end portion of the laminate 16 covers the area facing the bent portion 31 of the support plate 30 of the wireless power feeder 14.

[0034] The cushion layer 37 of the laminate 16 is in contact with the right surface of the left extension 33 of the cover member 15, the outer surface of the right wall 21 of the storage section 12, and the outer surface of the plastic panel 13. Therefore, the laminate 16 is arranged so as to cover a boundary 39 between the left extension 33 of the cover member 15 and the right wall 21 of the storage section 12, and a boundary 40 between the plastic panel 13 and the right wall 21 of the storage section 12.

[0035] <Function of the vehicle storage device 11> Next, the operation of the vehicle accommodation device 11 will be described. 2 to 4 , when water, an example of a liquid, is splashed onto the inner surface of the accommodation section 12, particularly onto the inner surface of the right wall 21, the water may infiltrate a gap at a boundary 40 between the resin panel 13 and the right wall 21 and a gap at a boundary 39 between the left extension 33 of the cover member 15 and the right wall 21. In this regard, in the vehicle accommodation device 11 of the present embodiment, these gaps are blocked from the outer surface side of the right wall 21 by the laminate 16. Therefore, even if water on the inner surface side of the right wall 21 flows from these gaps to the laminate 16 on the outer surface side of the right wall 21, the water is stopped by the resin layer 36 in the laminate 16, which has a water-stopping function. Therefore, the resin layer 36 of the laminate 16 prevents water from infiltrating from the inner surface side of the right wall 21 toward the wireless power feeder 14.

[0036] Furthermore, the laminate 16 covers a boundary portion 38 between the case 27 and the lid 28 of the wireless power feeder 14. Therefore, the resin layer 36 of the laminate 16 prevents water that has entered from the inner side to the outer side of the right wall 21 from entering the interior of the wireless power feeder 14 through a gap in the boundary portion 38 between the case 27 and the lid 28 of the wireless power feeder 14.

[0037] Furthermore, when the vehicle is driven, vibrations occur. If the wireless power feeder 14 vibrates due to such vibrations and comes into direct contact with the peripheral components of the wireless power feeder 14, such as the right wall 21, the resin panel 13, the cover member 15, and the support plate 30, abnormal noise is generated. In this regard, in the vehicle accommodation device 11 of this embodiment, the laminated body 16 is interposed between the wireless power feeder 14 and the peripheral components.

[0038] Therefore, when wireless power feeder 14 comes into contact with the peripheral components, it does so via laminate 16. Therefore, when wireless power feeder 14 comes into contact with the peripheral components via laminate 16 in a vibrating state, the vibrations are absorbed by cushion layer 37 of laminate 16. As a result, the cushion layer 37 of laminate 16 prevents wireless power feeder 14 from vibrating and repeatedly hitting the peripheral components, thereby preventing abnormal noise. Therefore, there is no problem even if wireless power feeder 14 comes into contact with the peripheral components via laminate 16 in a vibrating state, and therefore the distance between wireless power feeder 14 and the peripheral components can be narrowed, which ultimately contributes to space saving.

[0039] <Effects of the embodiment> According to the embodiment described above in detail, the following effects are achieved. (1) Vehicle storage device 11 includes storage section 12 having right wall 21 with power feed opening 23 formed therein and accommodating electronic device 22 inside right wall 21, resin panel 13 fitted into power feed opening 23 to close power feed opening 23, and wireless power feeder 14 wirelessly feeding power to electronic device 22 from outside right wall 21 through resin panel 13. Laminate 16 is disposed between a surface of wireless power feeder 14 facing right wall 21 and between right wall 21 and resin panel 13. Laminate 16 includes adhesive layer 35, resin layer 36 laminated on adhesive layer 35, and flexible cushion layer 37 laminated on a surface of resin layer 36 opposite to the adhesive layer 35 side.

[0040] Generally, the resin layer 36 has a liquid-proof function, and the cushion layer 37 has a shock- and vibration-absorbing function. According to the above configuration, the laminate 16 is disposed between the surface of the wireless power supply 14 on the right wall 21 side and the right wall 21 and the resin panel 13. Therefore, when a liquid such as water is splashed onto the housing 12, the resin layer 36 of the laminate 16 can prevent the liquid from penetrating from the inside of the right wall 21 through the gap at the boundary 40 between the resin panel 13 and the right wall 21 to the wireless power supply 14 located outside the right wall 21. Additionally, the cushion layer 37 of the laminate 16 absorbs vibrations of the wireless power supply 14 caused by vibrations generated during vehicle operation, etc. Therefore, it is possible to prevent the wireless power supply 14 from repeatedly hitting the right wall 21 and the resin panel 13 while vibrating, thereby preventing abnormal noise. Therefore, it is possible to prevent the liquid from penetrating the wireless power supply 14 side and the generation of abnormal noise.

[0041] (2) In the vehicle storage device 11, the stack 16 wraps around the wireless power feeder 14 and extends to the surface of the wireless power feeder 14 opposite to the surface on the right wall 21 side. According to the above configuration, the laminate 16 can be interposed between the surface of the wireless power feeder 14 opposite to the surface on the right wall 21 side and another component (in this example, the bent portion 31 of the support plate 30) close to that surface. Therefore, the cushion layer 37 of the laminate 16 can suppress the generation of abnormal noise caused by the surface of the wireless power feeder 14 opposite to the surface on the right wall 21 side hitting another component close to that surface due to vibrations generated during vehicle driving, etc.

[0042] (3) The vehicle storage device 11 includes the cover member 15 that contacts the upper end of the right wall 21 and covers the wireless power feeder 14 from above. The laminated body 16 is disposed so as to cover the boundary portion 39 between the cover member 15 and the right wall 21.

[0043] According to the above configuration, laminate 16 covers boundary portion 39 between cover member 15 and right wall 21. Therefore, when a liquid such as water is splashed onto housing portion 12, resin layer 36 of laminate 16 can prevent the liquid from entering from the inside of right wall 21 through the gap at boundary portion 39 between cover member 15 and right wall 21 to the wireless power feeder 14 side located outside the right wall 21.

[0044] (4) In the vehicle storage device 11, the wireless power feeder 14 includes a bottomed box-shaped case 27 having an opening 26 on the right wall 21 side, and a lid 28 fitted into the case 27 so as to close the opening 26. The stacked body 16 is arranged so as to cover a boundary portion 38 between the case 27 and the lid 28.

[0045] According to the above configuration, laminate 16 covers boundary 38 between case 27 and lid 28. Therefore, when liquid such as water enters the wireless power feeder 14 side of right wall 21, resin layer 36 in laminate 16 can prevent the liquid from entering the interior of wireless power feeder 14 through the gap at boundary 38 between case 27 and lid 28.

[0046] (5) In the vehicle storage device 11, the resin layer 36 is made of a polyethylene terephthalate film, the cushion layer 37 is made of a nonwoven fabric, and the adhesive layer 35 is made of a double-sided adhesive tape.

[0047] According to the above configuration, by forming the resin layer 36 from a polyethylene terephthalate film, when the resin layer 36 is welded to the cushion layer 37, the resin layer 36 melts and becomes thinner. By forming the cushion layer 37 from a nonwoven fabric, the cushion layer 37 can be made thinner than when the cushion layer 37 is formed from rubber, urethane foam, or the like. This contributes to a thinner laminate 16, which in turn contributes to space savings. In addition, by forming the adhesive layer 35 from a double-sided adhesive tape, the laminate 16 can be more easily adhered to a desired position than when the adhesive layer 35 is formed from an adhesive.

[0048] <Example of change> The above embodiment can be modified as follows: Furthermore, the above embodiment and the following modifications can be combined with each other within the scope of technical compatibility.

[0049] The resin layer 36 is not limited to a polyethylene terephthalate film, but may be made of a polypropylene film, for example. The cushion layer 37 is not limited to being made of nonwoven fabric, but may be made of, for example, urethane foam.

[0050] The adhesive layer 35 is not limited to a double-sided adhesive tape, and may be made of, for example, an adhesive agent. The laminate 16 does not necessarily have to be disposed so as to cover the boundary portion 38 between the case 27 and the lid 28 .

[0051] The laminate 16 does not necessarily have to be disposed so as to cover the boundary portion 39 between the cover member 15 and the right wall 21 . The cover member 15 may be omitted.

[0052] The laminate 16 does not necessarily have to extend around the wireless power feeder 14 to the surface of the wireless power feeder 14 opposite to the surface on the right wall 21 side. The laminate 16 may be attached to the wireless power supply device 14 by the adhesive layer 35 in a state where the laminate 16 partially covers the surface of the wireless power supply device 14 on the side of the right wall 21 .

[0053] The laminate 16 may be disposed so as to cover the entire wireless power supply device 14 . The vehicle storage device 11 is not limited to being provided in the center console, but may also be provided in the door trim, the instrument panel, or the like. [Explanation of symbols]
