The accommodating portion 2 is formed by defining an accommodating space by a bottom portion 21 and a side portion 22. Luggage requiring appropriate temperature control will be accommodated in this accommodation space.
The side portion 22 is provided so as to be expandable and contractible in the vertical direction, and the accommodation space, which is a space for accommodating luggage, can be increased or decreased between the extended state in which the side portion 22 is extended and the contracted state in which the side portion 22 is contracted. ..

The cover member 4 is a plate-shaped member that covers the upper part of the accommodating portion 2 so as to be openable and closable, and the upper surface of the grip portion 41 gripped by the user to pull out the accommodating portion 2 from the contracted state to the extended state. It is provided in. The cover member 4 is fixed to the accommodating portion 2 by an appropriate lock mechanism, a hook-and-loop fastener, a wire fastener, or the like in the contracted state and the extended state in which the load is already accommodated.
The side portion 22 and the cover member 4 of the accommodating portion 2 are formed of a light-shielding material in order to prevent sunlight that may enter from the side window or the front window in the vicinity of the seat 100 from hitting the luggage accommodated in the accommodating portion 2. It is preferable to be done.

The temperature control unit 3 adjusts the temperature inside the accommodating unit 2. The temperature control by the temperature control unit 3 is realized by introducing cold air or hot air into the accommodating unit 2 to maintain or raise or lower the temperature of the luggage accommodated in the accommodating unit 2.

The temperature control unit 3 has a control unit 31 and a transmission unit 32.
The control unit 31 controls the temperature control of the accommodating unit 2, and specifically controls the drive of the delivery unit 32. As the control unit 31, for example, an in-vehicle arithmetic unit for controlling the drive of various devices in the vehicle interior can be used.
The delivery unit 32 adjusts the temperature of the air and sends the temperature-controlled air toward the accommodating unit 2. As the delivery unit 32, for example, an in-vehicle heating, ventilation and air conditioning (HVAC) system can be used.
The control and operation of the control unit 31 and the transmission unit 32 will be described later.

When the accommodating portion 2 is pulled upward from the contracted state, it can be used in the extended state shown in FIG. 2, that is, it can accommodate luggage. The extended state of the accommodating portion 2 will be described with reference to FIG.
2 (a) to 2 (c) show an operation process of rotating the seat cushion 101 to store the load in the storage unit 2.

In order to bring the accommodating portion 2 into the extended state, first, as shown in FIG. 2A, the seat cushion 101 is moved from the seating position where the occupant can sit (the initial position indicated by the alternate long and short dash line) to the first shaft portion 103. By rotating it around the center, it moves upward to the separated position (solid line). As a result, the upper part of the storage case 105, which was closed by the seat cushion 101 before the movement, is opened, so that the upper area of the stored portion 2 in the contracted state is also opened.
Further, by gripping the grip portion 41 of the cover member 4 and pulling it upward, the folded side portion 22 extends in the vertical direction, and the accommodating portion 2 is in the extended state.

Next, as shown in FIG. 2B, by releasing what was fixed to the accommodating portion 2 of the cover member 4, the accommodating portion 2 is put into an uncovered state. As a result, the upper portion of the accommodating portion 2 is opened, so that the luggage B can be accommodated in the accommodating portion 2.

It should be noted that the baggage B preferably to be stored in the storage unit 2 is preferably temperature-controlled, and specifically, refrigerated foods, frozen foods, fresh foods, and perishable foods that require a temperature lower than normal temperature. Examples of foods that require a higher temperature than normal temperature include warm foods. Whether cold air or hot air is required may be set manually by the occupant or may be set automatically. As this automatic setting mode, for example, a temperature sensor is attached to the accommodating portion 2, and if it is detected that the luggage B is lower than normal temperature, the temperature setting is lowered and if it is detected that the temperature is higher than normal temperature. A form in which the temperature is set to a high temperature can be adopted.

As shown in FIG. 2C, the cover member 4 once removed from the upper part of the accommodating portion 2 is re-installed after accommodating the luggage B in the accommodating portion 2. As a result, the accommodating portion 2 is covered with the cover member 4, so that the inside of the accommodating portion 2 in which the luggage is accommodated becomes a substantially closed space.

The detection unit 5 shown in FIG. 1 detects the extension of the accommodating unit 2 and the fixing of the cover member 4. The extension of the accommodating portion 2 is detected when it is detected that the accommodating portion 2 exceeds a predetermined height when the accommodating portion 2 is pulled out upward by, for example, a sensor arranged at an appropriate height. And. Further, the fixing of the cover member 4 can be detected by, for example, a sensor that detects that the cover member 4 is once removed from the accommodating portion 2 and then fixed again.
As shown in FIG. 1, the detection unit 5 can output the detection result to the control unit 31 of the temperature control unit 3.

An inflow port 6 is provided on the side portion 22 on the front side of the accommodating portion 2. The inflow port 6 is a through hole formed in the accommodating portion 2, and is an opening for introducing air whose temperature is controlled by the sending portion 32 of the temperature controlling portion 3 into the accommodating portion 2. The inflow port 6 can adopt various forms as long as temperature-controlled air can be introduced. For example, the inflow port 6 may be a simple opening that is always open, and a fan that actively introduces air may be used. It may be attached, or a shutter that can be opened and closed may be attached.

Instead of the extended form of the accommodating portion 2 shown in FIG. 2, the upper portion of the accommodating portion 2 is substantially fixed to the back surface portion of the seat surface of the seat cushion 101 with, for example, a fastener, so that the seat cushion 101 is separated. It is also possible to adopt a form in which the accommodating portion 2 is pulled upward by the seat cushion 101 and is in an extended state as it moves upward to the position. In this case, the cover member 4 does not have to be provided, and the luggage B can be accommodated after the substantially fixed state of the accommodating portion 2 and the seat cushion 101 is temporarily released.

In the present invention, the accommodating portion can take various forms. Here, a modified example of the accommodating portion will be described with reference to FIG.
3 (a) to 3 (b) are schematic views showing an extended form of the accommodating portion different from the accommodating portion 2 shown in FIGS. 1 and 2 in the temperature control device according to the present invention. In the description of the embodiment shown in FIG. 3, when the same members as those shown in FIGS. 1 and 2 are used, the same reference numerals are given and detailed description thereof will be omitted.
The accommodating portions 210 and 220 shown in FIG. 3 have basically the same shape as the accommodating portion 2, extend in the same direction, and have substantially the same size.

In the embodiment shown in FIG. 3A, the seat cushion 101 is not moved when the accommodating portion 210 is pulled out upward. As shown in FIG. 3A, the temperature control device 11 is provided with an accommodating portion 210.

The accommodating portion 210 is moved forward from the seat 100 and then pulled out upward to be in an extended state. The movement of the accommodating portion 210 forward from the seat 100 can be achieved by attaching a slide mechanism 106 that allows the accommodating portion 210 to freely move in the front-rear direction by using a rail or the like at the lower part of the accommodating case 105. That is, the accommodating portion 210 moves to the front of the first position (storage case 105 indicated by the alternate long and short dash line), which is folded and arranged in the storage case 105 below the seat cushion 101. The slide mechanism 106 makes it possible to move between the second position (the storage case 105 shown by the solid line).
The slide mechanism 106 is an example of the movable portion of the accommodating portion in the present invention.

When the accommodating portion 210 is moved to the second position together with the accommodating case 105 by the slide mechanism 106, there is nothing that hinders the extension of the side portion 212 above the accommodating portion 210, so that the accommodating portion 210 can be extended without moving the seat cushion 101. It becomes a state. As a result, the accommodating portion 210 can be pulled out upward so that the side portion 212 can be extended and brought into an extended state.

The housing unit 210 in the extended state can store the luggage B inside by opening the cover member 4.
Further, the accommodating portion 210 accommodating the luggage B is covered again by the cover member 4, so that the inside becomes a closed space, and the preparation for temperature control by the temperature control portion 3 is completed.

In the embodiment shown in FIG. 3A, the accommodating portion 210 is in an extended state at a position particularly closer to the foot portion of the instrument panel 300 (hereinafter referred to as “instrument panel”) than in the embodiments shown in FIGS. 1 and 2. As a result, it becomes easy for cold air or warm air to flow into the accommodating portion 210 by the foot air conditioning, so that the temperature control efficiency can be improved.

In the embodiment shown in FIG. 3B, the seat cushion 101 is not moved when the accommodating portion 220 is pulled out upward. As shown in FIG. 3B, the temperature control device 12 is provided with an accommodating portion 220.

The accommodating portion 220 is extended upward by being pulled out from the floor portion 200. Specifically, the accommodating portion 220 is embedded in the floor portion 200 below the front side of the seat 100. A recess 201 is provided in the floor portion 200 where the foot is placed when the occupant is seated, and the accommodating portion 220 is folded in a contracted state and stored in the recess 201. In the embodiment shown in FIG. 3B, the cover member 420 is formed in a size and shape that can cover the upper portion of the accommodating portion 220 and also cover the recess 201 when it is stored in the recess 201. The grip portion 421 attached to the cover member 420 is provided on the lower surface side of the cover member 420 instead of the upper surface side in order to smooth the floor portion 200 so that the occupant can place his / her feet comfortably. A through hole is formed around the cover so that the user can reach it when gripping. The bottom portion 221 of the accommodating portion 220 is fixed to the bottom surface of the recess 201.

By gripping the grip portion 421 and pulling it upward from the recess 201 of the floor portion 200, the accommodating portion 220 changes from the contracted state in the recess 201 to the extended state.

The housing unit 220 in the extended state can store the luggage B inside by opening the cover member 420.
Further, the accommodating portion 220 accommodating the luggage B is covered again by the cover member 420, so that the inside becomes a closed space, and the preparation for temperature control by the temperature control portion 3 is completed.

In the embodiment shown in FIG. 3B, similarly to the embodiment shown in FIG. 3A, the accommodating portion 210 is located closer to the foot portion of the instrument panel 300 than in the embodiments shown in FIGS. 1 and 2. In the extended state, it becomes easy for cold air or warm air to flow into the accommodating portion 220 by the foot air conditioning, so that the temperature control efficiency can be improved.

Regarding the accommodating portion of the present invention, if the occupant sits on a seat provided with a temperature control device and the occupant does not feel a sense of discomfort or is difficult to remember when the occupant puts his / her foot on the floor portion, the accommodating portion 220 is used. It is not essential to bury it in the floor portion 200 by storing it in the recess 201 as described above.

Similar to the extended form of the accommodating portion, various forms of introducing air into the accommodating portion through the inflow port can be adopted as shown in FIG. Here, a mode of introducing air into the accommodating portion will be described with reference to FIG.
4 (a) to 4 (c) are schematic views showing a mode of introduction of the temperature-controlled air blown out from the temperature control section into the accommodating section. In the description of the embodiment shown in FIG. 4, when the same members as those shown in FIGS. 1 and 2 are used, the same reference numerals are given and detailed description thereof will be omitted.

The embodiment shown in FIG. 4A is the same as the embodiment shown in FIGS. 1 and 2, and specifically shows the introduction of air from the temperature control unit 3. As shown in FIG. 4A, the temperature-controlled air in the temperature control unit 3 arranged inside the instrument panel 300 is directed toward the inflow port 6 via the air outlet 301 arranged in the foot region of the sheet 100. It is blown into the passenger compartment. The air blown out from the outlet 301 travels substantially straight and flows into the accommodating portion 2 through the inflow port 6 provided on the front side portion 22 of the accommodating portion 2.
In the embodiment shown in FIG. 4A, the temperature control unit 3 shares a member (heating, ventilation, air conditioning (HVAC) system, etc.) provided inside the instrument panel 300 for air conditioning of the entire vehicle interior. The control unit 31 of the temperature control unit 3 normally adjusts the temperature for air conditioning in the vehicle, and only for the air blown out toward the accommodation unit 2, the temperature setting is made independent of the air conditioning setting for the entire vehicle interior, so that the luggage is loaded. It is possible to realize an arbitrary set temperature according to the properties of.

The embodiment shown in FIG. 4 (b) is a modification of the air introduction route of the embodiment shown in FIG. 4 (a). As shown in FIG. 4B, the temperature control device 13 is provided with a duct 33. The air whose temperature is controlled by the temperature control unit 3 arranged inside the instrument panel 300 reaches the sheet 100 through a duct 33 which is embedded under the floor unit 200 and extends below the sheet 100. Further, the air from the temperature control portion 3 flows into the accommodating portion 2 through the inflow port 61 formed by inserting the end portion of the duct 33 through the bottom portion 21 of the accommodating portion 2.
In the embodiment shown in FIG. 4 (b), similarly to the embodiment shown in FIG. 4 (a), the temperature control unit 3 shares a member (HVAC system or the like) used for air conditioning of the entire vehicle interior. By using the duct 33 extending to the accommodating portion 2 via the lower part of the floor portion 200, it is not necessary to consider the diffusion of the blown air into the vehicle interior, and the temperature is surely controlled in the accommodating portion 2. Air can be introduced.

As a further modification of the embodiment shown in FIG. 4B, a mode in which the duct 33 of the temperature control device 11 is also used for seat air conditioning can be mentioned. Specifically, this modification includes a duct arranged inside the seat cushion 101 and the like for air conditioning in which temperature-controlled air is blown out from the seat cushion 101 and the seat back 102 of the seat 100, and the duct 33. The duct 33 shown in FIG. 4B is extended upward so that the end portion of the seat cushion 101 can be connected to the seat cushion 101 when the seat cushion 101 is in the seating position. According to this form, when the seat cushion 101 is in the seating position without moving upward, the seat air conditioning is performed for the occupant seated in the passenger seat, and when the seat cushion 101 is moved upward and is in the separated position, the luggage B is performed. It is possible to control the temperature of the air conditioner, and it becomes possible to cope with various situations by using cold air and warm air without waste.

In the embodiment shown in FIG. 4 (c), an independent temperature control unit 30 is arranged on the sheet 100. As shown in FIG. 4C, in the temperature control device 14, the temperature control unit 30 is arranged on the floor portion 200, inside the base member 107 for fixing and arranging the seat 100, and behind the accommodating portion 2. It is provided. The air whose temperature is controlled by the temperature control unit 30 flows into the accommodating unit 2 through the inflow port 62 provided on the rear side portion 22 of the accommodating unit 2.
In the embodiment shown in FIG. 4 (c), the temperature control unit 30 is provided as a separate member independent of the member (HVAC system or the like) used for air conditioning of the entire vehicle interior provided inside the instrument panel 300. Since the temperature control unit 30 is attached to the sheet 100 and is close to the accommodating unit 2, the unintended temperature of the air is reached between the time when the temperature control unit 30 is blown out and the time when the temperature control unit 30 is introduced into the accommodating unit 2. It is hard to change.

Here, the control when the temperature control device 1 is used will be described with reference to FIG.
Note that FIG. 5 is a flowchart showing a control flow when the temperature of the accommodating portion 2 is adjusted by using the temperature control device 1 shown in FIGS. 1, 2 and 4 (a).

First, the occupant seated in the driver's seat with the luggage B moves the seat cushion 101 of the passenger seat 100 upward (step S1). By this step, the upper part of the storage case 105 covered with the seat cushion 101 is opened.
This step is basically performed manually to simplify the seat structure, but if necessary, a vertical movement switch for the seat cushion 101 is provided in the vehicle interior, and an actuator or the like is provided on the first shaft portion 103. It may be automated by this.

Next, the occupant in the driver's seat grips and pulls up the grip portion 41 of the cover member 4 in the accommodating portion 2 in the contracted state in the storage case 105 (step S2). By this step, the side portion 22 which has been folded is extended by pulling out the accommodating portion 2 upward, and the accommodating portion 2 is in the extended state. As a result, the volume inside the accommodating portion 2 is expanded so that the luggage B can be accommodated.

Next, the luggage B carried by the occupant is accommodated in the accommodating portion 2 (step S3). In this step, the occupant can place the luggage B in the accommodating portion 2 in substantially the same operation as the operation of placing the luggage B on the adjacent seat cushion 101, so that the operation is completed with a simple operation.
It is preferable that the control unit 31 sets the temperature of the air blown toward the accommodation unit 2 by the delivery unit 32 in the temperature control unit 3 before and after the storage operation of the luggage B. The temperature may be set manually by the occupant, or a temperature sensor may be attached to the accommodating portion 2 and the temperature may be automatically set to maintain the temperature according to the temperature of the baggage B.

Further, the control unit 31 of the temperature control unit 3 determines whether or not the storage unit 2 accommodating the luggage B is covered by the cover member 4 (step S4). In this step, based on the detection result of the detection unit 5, it is determined that the collection cover member 4 is fixed to the accommodation unit 2, that is, the internal region of the accommodation unit 2 including the luggage B is a closed area. In this case, the process proceeds to the next step (YES in step S4). If it is determined that the cover member 4 is not fixed, this step is repeated until the cover member 4 is fixed (NO in step S4).
In the present embodiment, the detection unit 5 can also detect whether or not the sheet 100 is fixed at a separated position. Therefore, in this step, instead of whether or not the cover member 4 is fixed, or the cover member 4 is fixed. Along with the presence or absence of the sheet 100, whether or not the sheet 100 is fixed may be used as a determination target.

When the cover member 4 is fixed (YES in step S4), the control unit 31 of the temperature control unit 3 determines whether or not the foot air conditioner installed in front of the seat 100 is being driven (step). S5). In the present embodiment, the temperature control unit 3 used for air conditioning for the entire vehicle interior, that is, for the occupants, is also shared for temperature control of the accommodation unit 2, so that the foot of the seat 100, that is, the vicinity of the accommodation unit 2 is already shared. It is necessary to separate the operation mode of the temperature control unit 3 depending on whether or not the air conditioning is performed.

When the foot air conditioning of the seat 100 by the temperature control unit 3 is driven (YES in step S5), only the foot air conditioning is changed to the setting suitable for the luggage B in the temperature setting of the sending air in the sending unit 32 (step S62). ). The foot air conditioning by the temperature control unit 3 may be maintained to be driven.
If the foot air conditioning of the seat 100 is not driven (NO in step S5), the delivery unit 32 is driven for the luggage B (step S61).
Regardless of the determination result of the previous step (step S5), as a result, as shown in FIG. 4A, the air whose temperature is controlled by the delivery unit 32 is the air outlet provided in the lower part of the instrument panel 300. It flows into the accommodating portion 2 through the 301 and the inflow port 6 provided on the front side portion 22 of the accommodating portion 2. As a result, the luggage B is maintained at a temperature lower or higher than the normal temperature, which is the temperature intended by the occupant.

In the present embodiment, the temperature control of the accommodating unit 2 by the temperature control unit 3 is performed independently of the air conditioning of the entire vehicle interior for the occupant, in particular, the temperature setting of the delivery air of the delivery unit 32 is performed. Normally, the air conditioning of the entire vehicle interior is around 25 ° C for cooling and around 30 ° C for heating, but for example, for refrigerated foods and frozen foods, it is 15 ° C or less, and for warm lunch boxes, etc. The temperature is preferably 35 ° C. or higher. By making the settings and controls related to temperature control independent for the entire vehicle interior and for the accommodation unit 2, appropriate air conditioning for both the occupant and the luggage B becomes possible.

The temperature control device according to the present invention can be easily used by a occupant seated in the driver's seat with one hand when placing luggage in an adjacent passenger's seat area. In order to facilitate the use of the temperature control device with one hand, it is preferable that the seat cushion and the accommodating portion have a structure that can be easily moved upward from the driver's seat side, for example. For this purpose, the first shaft portion described above as one form of the movable portion of the seat cushion is arranged on the front end side or the rear end side of the seat cushion along the left-right direction of the vehicle, or on the window side of the seat cushion. It is possible to adopt a form in which the side portion is arranged along the front-rear direction of the vehicle. Further, in order to facilitate the upward pulling out of the accommodating portion, a spring mechanism or the like that can be expanded and contracted in the vertical direction may be provided on the side portion or the like.
In the above-described embodiment, the upward movement form of the seat cushion is a rotation form centered on the shaft-shaped member, but instead of the shaft-shaped member, a spring mechanism or the like that can be expanded and contracted in the vertical direction is provided on the seat cushion.
