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, the storage structure shown in Patent Document 1. This storage structure includes a recess for storing electronic devices, and a wireless power supply unit that is provided on a side surface of the recess and wirelessly supplies power to the electronic devices stored in the recess. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 2021-133734 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the above-described storage structure, when the wireless power supply unit is configured as a wireless power supply device using the electromagnetic induction method, the following problem occurs: When the wireless power supply unit outputs power while a metal piece such as a coin is inserted into the recess and placed against the wireless power supply unit, the magnetic flux generated by the coil of the wireless power supply unit passes through the metal piece, causing an eddy current to flow in the metal piece, causing the metal piece to heat up. [Means for solving the problem]

[0005] Various aspects of the vehicle storage device for solving the above problems will be described below. [Aspect 1] A vehicle storage device comprising: a storage section having a bottom wall and side walls and for storing electronic devices inside the side walls; and a wireless power supply device for wirelessly supplying power to the electronic devices from outside the side walls through the side walls, wherein a groove extending along the side walls is formed at the end of the inner surface of the bottom wall facing the side walls, and the depth of the groove increases with increasing distance from the wireless power supply device.

[0006] When the wireless power supply is an electromagnetic induction type, if an electronic device is housed in the housing and a disk-shaped metal piece, such as a coin, is placed against the side wall of the housing in a position corresponding to the wireless power supply, and power is supplied to the electronic device by the wireless power supply, the following problem occurs. Specifically, when a magnetic flux generated by a coil in the wireless power supply passes through the metal piece, eddy currents flow through the metal piece, causing the metal piece to heat up. In this regard, with the above configuration, when a disk-shaped metal piece is placed against the side wall of the housing in a position corresponding to the wireless power supply, a portion of the periphery of the metal piece is inserted into the groove. Since the groove then becomes deeper with increasing distance from the wireless power supply, the metal piece rolls down the groove due to gravity and moves away from the wireless power supply. Therefore, even when the wireless power supply outputs power with the disk-shaped metal piece inserted in the housing, heat generation by the metal piece can be suppressed.

[0007] [Aspect 2] The wireless power supply is positioned at a position corresponding to the center of the groove, and the groove is characterized in that it becomes deeper from the center toward both ends.

[0008] According to the above configuration, since the groove is deeper from the center toward both ends, when a disk-shaped metal piece is inserted into the center of the groove, the metal piece rolls down the groove due to gravity and moves to one of the ends of the groove. Therefore, since the metal piece moves away from the wireless power feeder, heat generation by the metal piece can be suppressed even when an electronic device is placed in the housing with the disk-shaped metal piece housed in the housing and power is supplied to the electronic device by the wireless power feeder.

[0009] [Aspect 3] A vehicle storage device as described in [Aspect 1] or [Aspect 2], characterized in that the bottom wall is inclined so that the groove side is lower, and a drain hole for draining liquid is formed in the deepest part of the groove.

[0010] According to the above configuration, if a liquid such as water gets into the container, the liquid will flow along the bottom wall to the groove due to gravity, then flow along the groove toward the drain hole and be discharged through the drain hole. Therefore, even if liquid gets into the container, it is possible to prevent the liquid from remaining pooled inside the container. [Effects of the Invention]

[0011] The present invention has an advantage that heat generation by the metal piece can be suppressed even when the wireless power feeder outputs power with the disk-shaped metal piece inserted in the housing. [Brief explanation of the drawings]

[0012] [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 a cross-sectional view taken along line 3-3 in FIG. 2. [Figure 4] FIG. 10 is a cross-sectional view of a modified example of a vehicle storage device. DETAILED DESCRIPTION OF THE INVENTION

[0013] 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.

[0014] <Vehicle storage device 11> 1 and 2, the vehicle accommodation device 11 is provided, for example, by being incorporated into a center console disposed between the driver's seat and the passenger seat in the vehicle interior. The vehicle accommodation device 11 includes a storage unit 12 and a wireless power feeder 13.

[0015] <Containment Unit 12> 1 and 2, the storage compartment 12 is made of resin and has the shape of a rectangular box 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 14, a front wall 15, a rear wall 16, a left wall 17, and a right wall 18 that is an example of a side wall. The bottom wall 14, the front wall 15, the rear wall 16, the left wall 17, and the right wall 18 are all rectangular.

[0016] A rectangular, plate-shaped electronic device 19 such as a smartphone is housed in the space inside the bottom wall 14, front wall 15, rear wall 16, left wall 17, and right wall 18, i.e., inside the housing section 12. In this case, the electronic device 19 is inserted into the housing section 12 from the opening at the top end in a horizontal position with the long side oriented in the front-to-rear direction. The electronic device 19 is compatible with wireless power supply.

[0017] A groove 21 extending in the front-to-rear direction along the right wall 18 is formed on the inner surface 20 (upper surface) of the bottom wall 14 at an end on the right wall 18 side. The groove 21 has a rectangular shape in cross section. The groove 21 extends from the front end to the rear end of the inner surface 20 of the bottom wall 14. The bottom surface of the groove 21 and the side surface of the groove 21 opposite to the right wall 18 side are formed by the bottom wall 14. The side surface of the groove 21 on the right wall 18 side is formed by the right wall 18.

[0018] 1 to 3, the width of groove 21 is set to allow insertion of a disk-shaped metal piece 22, such as a 500 yen coin, for example. The depth of groove 21 is set to allow insertion of part of the peripheral edge of metal piece 22. Groove 21 gradually becomes deeper from the center toward both ends in the front-to-rear direction.

[0019] The deepest part of the groove 21 is formed with drain holes 23 for draining liquid such as water that has entered the storage section 12. In this case, the deepest parts of the groove 21 are both ends in the front-rear direction of the groove 21. Therefore, the groove 21 is formed with one drain hole 23 at each end in the front-rear direction (two in total).

[0020] 2, the housing section 12 is disposed in a state inclined at about 20° to the right. Therefore, the bottom wall 14 is inclined so that the groove 21 side is lower. When the electronic device 19 is placed in the housing section 12 and leaned against the right wall 18, the state is maintained by gravity. That is, in this case, the electronic device 19 is maintained in a state in which one surface thereof is in contact with the inner surface of the right wall 18 due to gravity.

[0021] <Wireless power supply 13 and groove 21> 1 to 3, wireless power feeder 13 is disposed on the right side (outside) of the center in the front-rear direction of right wall 18. That is, wireless power feeder 13 is disposed at a position corresponding to the center in the front-rear direction of groove 21. In this case, as described above, groove 21 gradually becomes deeper from the center in the front-rear direction toward both end portions. Therefore, it can be said that groove 21 gradually becomes deeper with increasing distance from wireless power feeder 13.

[0022] The wireless power feeder 13 wirelessly feeds power to the electronic device 19 housed inside the right wall 18 from the right side (outside) of the right wall 18 over the right wall 18 by electromagnetic induction. That is, the wireless power feeder 13 feeds power to the electronic device 19 by utilizing electromagnetic induction between its transmitting coil (not shown) and a receiving coil (not shown) of the electronic device 19.

[0023] <Function of the vehicle storage device 11> Next, the operation of the vehicle accommodation device 11 will be described. 1 to 3, the wireless power feeder 13 in the vehicle storage device 11 is of an electromagnetic induction type. Therefore, if a disk-shaped metal piece 22, such as a coin, is leaned against the right wall 18 of the storage section 12 in a position corresponding to the wireless power feeder 13, and if an electronic device 19 is stored in the storage section 12 and power is supplied to the electronic device 19 by the wireless power feeder 13, the following problem occurs: That is, when a magnetic flux generated by a transmission coil on the wireless power feeder 13 side passes through the metal piece 22, an eddy current flows in the metal piece 22, causing the metal piece 22 to heat up.

[0024] In this regard, in the vehicle storage device 11 of the present embodiment, when a disk-shaped metal piece 22 is placed against the right wall 18 of the storage section 12 at a position corresponding to the wireless power feeder 13, a part of the peripheral edge of the metal piece 22 is inserted into the groove 21. Then, since the depth of the groove 21 increases with increasing distance from the wireless power feeder 13, the metal piece 22 rolls in the groove 21 due to gravity and moves away from the wireless power feeder 13.

[0025] That is, metal piece 22 rolls from the center of groove 21 shown by the solid line in Fig. 3 to both ends of groove 21 shown by the two-dot chain line in Fig. 3, and moves to a position outside wireless power feeder 13. Therefore, even when wireless power feeder 13 outputs power with disk-shaped metal piece 22 inserted in housing 12, heat generation by metal piece 22 is suppressed.

[0026] Furthermore, if a liquid such as water gets into the storage section 12, the liquid in the storage section 12 will flow due to gravity on the inner surface 20 of the bottom wall 14 toward the grooves 21. Then, the liquid that has flowed from the inner surface 20 of the bottom wall 14 into the grooves 21 will flow due to gravity toward the drain holes 23 at both ends of the grooves 21 and be discharged from the drain holes 23. In other words, even if liquid gets into the storage section 12, the liquid that has entered the storage section 12 will be quickly discharged from the drain holes 23. This prevents the liquid from remaining pooled in the storage section 12. This prevents items stored in the storage section 12 from getting wet with liquid such as water.

[0027] <Effects of the embodiment> According to the embodiment described above in detail, the following effects are achieved. (1) The vehicle storage device 11 has a bottom wall 14 and a right wall 18, and includes a storage section 12 that stores an electronic device 19 inside the right wall 18, and a wireless power feeder 13 that wirelessly feeds power to the electronic device 19 from outside the right wall 18 through the right wall 18. A groove 21 extending along the right wall 18 is formed at an end of the inner surface 20 of the bottom wall 14 on the right wall 18 side. The depth of the groove 21 increases with increasing distance from the wireless power feeder 13.

[0028] According to the above configuration, when disk-shaped metal piece 22 is placed against the right wall 18 of housing 12 at a position corresponding to wireless power feeder 13, part of the peripheral edge of metal piece 22 is inserted into groove 21. Then, since groove 21 becomes deeper with increasing distance from wireless power feeder 13, metal piece 22 rolls in groove 21 due to gravity and moves away from wireless power feeder 13. Therefore, even when wireless power feeder 13 outputs power with disk-shaped metal piece 22 inserted in housing 12, heat generation by metal piece 22 can be suppressed.

[0029] (2) In the vehicle accommodation device 11, the wireless power feeder 13 is disposed at a position corresponding to the center of the groove 21. The depth of the groove 21 increases from the center toward both ends.

[0030] According to the above configuration, groove 21 becomes deeper from the center toward both ends, so when disk-shaped metal piece 22 is inserted into the center of groove 21, metal piece 22 rolls in groove 21 by gravity and moves to one of the ends of groove 21. Therefore, metal piece 22 moves away from wireless power feeder 13, and therefore, even if electronic device 19 is accommodated in accommodation section 12 with disk-shaped metal piece 22 accommodated in accommodation section 12 and power is fed to electronic device 19 by wireless power feeder 13, heat generation by metal piece 22 can be suppressed.

[0031] (3) In the vehicle storage device 11, the bottom wall 14 is inclined so that the groove 21 side is lower. In the deepest part of the groove 21, a drain hole 23 for draining liquid is formed. According to the above configuration, if a liquid such as water gets into storage section 12, the liquid in storage section 12 flows by gravity on inner surface 20 of bottom wall 14 to groove 21, and then flows through groove 21 toward drain hole 23 and is discharged from drain hole 23. Therefore, even if liquid gets into storage section 12, it is possible to prevent the liquid from remaining accumulated inside storage section 12.

[0032] <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.

[0033] As shown in Fig. 4, the vehicle storage device 11 may be modified as follows. That is, the groove 21 is configured to gradually become deeper from the front end to the rear end. The wireless power feeder 13 is disposed in a position corresponding to a position in the groove 21 that is closer to the front than the center in the fore-and-aft direction. Only one discharge hole 23 for discharging liquid is formed in the groove 21 at the rear end, which is the deepest part. Even with this configuration, the same effects as those in (1) and (3) above can be obtained.

[0034] The discharge hole 23 may be omitted from the vehicle storage device 11 shown in FIG. The bottom wall 14 does not necessarily have to be inclined so that the groove 21 side is lower. At least one of the two discharge holes 23 may be omitted.

[0035] The number and positions of the discharge holes 23 formed in the groove 21 may be changed as appropriate. 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]
