  However, in the above lighting structure, the switch structure and the light source can be seen as they are, and there is a design problem that the appearance is deteriorated and the sense of quality is impaired, and the illumination of the storage container without the lid is directly in the eyes and dazzling. May interfere with driving.

  Since the illumination of the door trim unit panel shown in Patent Document 2 is an illumination mode, it cannot be lit alone in conjunction with a headlight switch, a room lamp switch, etc., and there is a problem as illumination of the storage container. On the other hand, when the light is turned on by a switch operation, it is convenient if the switch is interlocked with the operation of opening the lid. However, when the illumination of the open container is always turned on by the switch operation, the convenience is impaired.

  Further, when a switch is provided in the container, there is a problem that an erroneous operation is likely to occur in a situation not intended by the operator due to a structure in which a storage space is reduced and an object hits the switch.

  In order to solve the above problems, a storage container according to the present invention is a storage container that is provided in a vehicle interior material and is partially opened, and is provided on an inner surface of an opening of the storage container. At least one human body approach detection unit for detecting the approach or contact of the storage container, and one side of the inner surface of the storage container between the bottom surface of the storage container and the human body approach detection unit. A plurality of light emitting elements arranged so as to irradiate light toward a side opposite to one side of the inner surface of the storage container, and the approach of the human body to detect the approach of the human body, Or at least one is provided with the control part which controls lighting or light extinction, and provided the in-container lighting fixture.

  Further, in the in-container illumination device according to the present invention, the human body approach detection unit detects a change in stray capacitance, and the control unit includes at least a change in capacity due to the approach or contact of a part of the human body, and at least put in the storage container. And a lighting control means for controlling lighting or extinguishing of all or at least one of the light emitting elements based on the discrimination means. And

  In the method for controlling a plurality of light emitting elements provided in a storage container for a vehicle interior material according to the present invention, a part of a human body approaches or comes into contact with at least one human body approach detection unit provided on the inner surface of the opening of the container. A human body approach detecting step, a capacity change due to the approach or contact of a part of the human body, a capacity change due to movement of at least a container, and a discrimination process based on the discrimination process. A lighting control step of controlling lighting or extinguishing of all or at least one of the light emitting elements.

  By using the present invention, in the in-container illumination of the storage container, independent lighting is possible in conjunction with a headlight switch, a room lamp switch, etc., regardless of the illumination mode. This in-container lighting has an effect that it is possible to obtain light without performing a switch operation when it is desired to take out an object from the container. Specifically, when a hand is brought close or lightly touched, a capacitance switch provided at an opening of a storage container such as a door pocket reacts and lights up.

  Another effect is that the light source is incorporated into the inner wall, and so-called indirect illumination is performed by irradiating and reflecting the light on the opposite inner wall, so that the light source can not be seen by the passenger and the glare can be reduced, improving the sense of quality and design. To do. In addition, it is possible to reduce an erroneous operation in a situation not intended by the passenger without reducing the space in the storage container.

  Hereinafter, embodiments of the present invention (hereinafter referred to as embodiments) will be described with reference to the drawings.

  FIG. 1 is a perspective view of a door trim 10 having a pocket portion 10a according to an embodiment of the present invention. A door pocket storage container 20 is fixed to the door pocket portion 10a from the back side of the door trim 10 with an adhesive or a screw. When the passenger's hand 28 is brought closer, the touch sensor 15 detects a change in capacitance, and a control circuit (not shown) turns on the illumination LED 14 and irradiates light diffused in the direction of the arrow in the figure. The touch sensor 15 is arranged on the driver's seat side because it is easier to touch with the palm of the hand than with the back of the hand, and is ergonomically matched with the direction of flow line that attracts objects.

  FIG. 2 is a perspective view of the door pocket storage container 20 fixed from the back side of the door trim 10 in which the pocket portion 10a according to the embodiment of the present invention is formed. The door pocket storage container 20 has a case 11 and an inner panel 12 facing the back surface of the pocket portion 10a of the door trim 10, and the capacity of the door pocket storage container 20 is determined by these components. The case 11 has an ECU controller 24 on the side surface. The inner panel 12 has a flexible printed circuit board 16. The flexible printed circuit board 16 has a touch sensor 15 and a plurality of illumination LEDs 14 and is connected to an ECU controller 24.

  FIG. 3 is an exploded perspective view in which the door pocket storage container 20 according to the embodiment of the present invention is disassembled into parts. In order to facilitate temporary assembly, the case 11 is provided with a plurality of fastener portions 11a for temporarily fixing the door trim 10, the inner panel 12, and the like, and are fixed with an adhesive or screws. The inner panel 12 is a tactile sensation improving panel and is assembled to the case 11. The normal purpose of use is to obtain a high-class feeling by providing a panel on the interior material of the door trim surface. In this embodiment, a flexible printed circuit board 16 is fixed to the inner panel 12 and a milky white or transparent panel provided with a diffusing lens 13 for illumination is used. In this way, all functions are integrated in the door pocket storage container 20 alone.

  An electrode pattern of the touch sensor 15 and an illumination LED 14 are wired on the flexible printed board 16, and these are connected to the ECU board 18 by a flexible flat cable 17. The ECU board 18 includes an input recognition circuit for the touch sensor 15, a lighting control circuit for the LED 14, and a power cable connector 22. The ECU board 18 is fixed to the ECU housing portion 11b of the case 11 and is further protected by an ECU cover 21 for preventing dust.

  FIG. 4 is a configuration diagram showing a circuit configuration of the door pocket storage container lighting device 30 according to the embodiment of the present invention. The door pocket storage container lighting tool 30 includes a touch sensor 15, a control circuit 34, and a plurality of lighting LEDs 14.

  When the user reaches for the touch sensor 15, the capacitance increases, and further, the capacitance of the human body is transmitted from the touch sensor 15 to the control circuit 34. The control circuit 34 detects that the acquired change rate of capacitance is a value exceeding a predetermined change rate and / or a value exceeding a steady capacitance, and turns on the illumination LED 14.

  The control of the control circuit 34 is basically LED re-click lighting by touching with a hand, but when the on state continues for about 15 seconds, the timer function automatically turns off. It should be noted that the control circuit 34 prevents malfunction that prevents the illumination LED 14 from malfunctioning because the stored item in the pocket moves due to the shaking of the vehicle and the capacitance increases even though the operator does not actually touch it. Processing is being executed.

  Specifically, the capacitance is measured at regular intervals to monitor the increase / decrease in the stored items, and the capacitance and the rate of change of capacitance when the passenger touches are stored, and the threshold value is corrected. Processing is in progress. This is also effective when the capacitance varies with humidity.

  As described above, according to the present embodiment, the illumination quality is improved by incorporating the illumination so that the contents of the storage container provided as the interior material for the vehicle can be seen bright at night, and the human body By adding a function that lights up in accordance with the above operation, there is an effect that it is possible to realize interior lighting that is closer to human sensitivity.

  In this way, by using this embodiment, independent lighting is possible in conjunction with the headlight switch, room lamp switch, etc. regardless of the illumination mode, and the switch operation is performed when it is desired to take out the item from the case. It became possible to get lighting without. In this embodiment, the operation is performed regardless of the illumination mode. However, the operation process may be changed by detecting the illumination mode.

  As shown in the door pocket storage container of this embodiment, by incorporating a light source into the inner wall and using indirect illumination, glare can be reduced because the light source is not visible to the passenger, and luxury and design are improved. In addition, it has become possible to reduce erroneous operations in situations where the passenger does not intend without reducing the space in the pocket.

In addition, by providing an electrostatic switch and a light source on the inner wall, the possibility of direct application of beverages or the like is reduced, and the function as a container can be fully exhibited. In this embodiment, the door pocket storage container, which is a storage container without a lid, has been described, but it goes without saying that the same effect can be obtained by using it for a storage container having a lid. In this case, it is preferable to provide a plurality of touch sensors 15 and also arrange them on the lid.
In this embodiment, since the overhang of the pocket portion is large, it is flexible. Although a printed board is used, a generally used rigid board may be used when there is an installation space. Furthermore, the electrode of the touch sensor may be anything as long as it has conductivity, for example, a conductive tape or a wire harness.
