Description

The present invention relates to a vehicle floor structure.

For example, Patent Document 1 discloses a structure in which a deodorizing device containing a deodorizing agent is built into the front part of a floor mat placed in a vehicle interior so that the floor mat is raised to form a footrest.

The raised portion of the floor mat is provided with a plurality of holes, and the odor of the feet placed on the raised portion is guided to the deodorizing device and deodorized.

Japanese Patent Application Publication No. 2011-126508

In Patent Document 1, although foot odor can be deodorized by a deodorizing device built into a floor mat, the foot is only placed on the floor mat and the foot is exposed to the passenger compartment. Therefore, there is a concern that the foot odor may be diffused into the vehicle interior.

In view of these circumstances, the present invention secures a space on the floor of the vehicle interior to cover the occupant's feet and objects, and when the occupant's feet or objects emit an odor, the odor is removed from the vehicle interior. The purpose is to provide a vehicle floor structure that allows exhaust to the outside.

The floor structure of a vehicle according to the present invention includes a vent installed in a floor panel of the vehicle and a floor carpet laid on the floor panel so as to communicate between the inside and outside of the vehicle compartment, and a vent hole in the floor carpet. a cover that is attached to the passenger compartment side so as to cover the installation area of the ventilation opening of the floor carpet, has an insertion/extraction opening for allowing the occupant's feet or articles to be put in and taken out, and is stretchable; an exhaust cover that is attached to cover the installation area of the vent in the floor panel and has an exhaust port that opens rearward at the rear of the vehicle in the front-rear direction; It is characterized by comprising a lid that is provided to close, and a drive device that opens or closes the lid.

According to this configuration, it is possible to secure a space on the floor in the vehicle interior to cover the occupant's feet and articles, so that the occupant's feet can be placed between the cover and the floor carpet.

Thereby, for example, when the air inside the vehicle is cold, it is possible to prevent the feet of the occupant from becoming cold due to the foot being inserted between the cover and the floor carpet.

Further, when the occupant's feet or an object is placed between the cover and the floor carpet as described above, if the lid is opened by the drive device, the gap between the cover and the floor carpet is This makes it possible to exhaust air from the exhaust port to the outside of the passenger compartment.

As a result, if the feet or objects inserted between the cover and the floor carpet emit an odor, the odor from the feet or objects can be discharged to the outside of the vehicle interior, so that the occupants can feel comfortable in the vehicle interior. It becomes possible to spend time.

Incidentally, in the floor structure of the vehicle, the exhaust port may be provided at a location where negative pressure is generated outside the exhaust cover while the vehicle is running or at a location where the pressure is lower than in the vehicle interior. can.

According to this configuration, for example, when the vehicle is running, the outer part of the exhaust port of the exhaust cover becomes a place where negative pressure is generated by the running wind passing under the floor panel, so that negative pressure is generated at this place. Due to the negative pressure, air between the cover and the floor carpet is sucked and discharged from the exhaust port to the outside of the vehicle interior.

In this way, simply by running the vehicle, the air between the cover and the floor carpet can be efficiently exhausted to the outside of the vehicle interior from the exhaust port without installing new air blowing equipment inside the cover. It becomes like this.

On the other hand, when the vehicle is stopped or running at low speed, when heated air, cooled air, or blown air is introduced into the vehicle interior by the vehicle's existing air conditioning equipment, the pressure in the vehicle interior increases and the air is exhausted from the exhaust cover. Since the outside portion of the opening is a location where the pressure is lower than the pressure inside the vehicle interior, the air between the cover and the floor carpet is forced out of the exhaust port to the outside of the vehicle interior.

In this way, by simply operating the existing air conditioning equipment in the vehicle, the air between the cover and the floor carpet can be pumped into the vehicle interior through the exhaust port without the need to install new air blowing equipment inside the cover. This allows for efficient drainage to the outside.

The floor structure of the vehicle further includes a switch that outputs an on signal in response to a human on operation and an off signal in response to a human off operation, and the drive device The lid may be placed in an open state in response to an on signal from the switch, and closed in response to an off signal from the switch.

According to this configuration, when an on signal is output from the switch, the drive device opens the lid, so that the air between the cover and the floor carpet is discharged from the exhaust port to the outside of the vehicle interior. It becomes possible to discharge.

On the other hand, when an off signal is output from the switch, the drive device closes the lid, so air from outside the vehicle compartment cannot enter between the cover and the floor carpet through the exhaust port. Prevented.

Further, the floor structure of the vehicle detects the condition when the foot of the occupant or the article is inserted between the cover and the floor carpet and outputs a detection signal, and also detects the condition. The drive device further includes a sensor that outputs a non-detection signal when the lid is not detected, and the drive device opens the lid in response to the detection signal from the sensor, and opens the lid in response to the non-detection signal from the sensor. The lid may be configured to be in a closed state.

According to this configuration, when a detection signal is output from the sensor, the drive device opens the lid. This makes it possible to exhaust air between the cover and the floor carpet to the outside of the vehicle interior through the exhaust port.

On the other hand, when a non-detection signal is output from the sensor, the drive device closes the lid. This prevents air from outside the vehicle interior from entering between the cover and the floor carpet through the exhaust port.

Further, in the floor structure of the vehicle, a heater may be installed inside the cover.

According to this configuration, by operating the heater, the space between the cover and the floor carpet is heated, so that if the occupant's feet are inserted between the cover and the floor carpet, the feet of the occupant can be warmed. become.

According to the present invention, a space is secured on the floor of the vehicle interior to cover the occupant's feet and objects, and if the occupant's feet or objects emit an odor, the odor can be discharged to the outside of the vehicle interior. It has the excellent effect of

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, best embodiments for carrying out the present invention will be described in detail with reference to the accompanying drawings.

An embodiment of the present invention is shown in FIGS. 1 to 4. In the illustrated vehicle floor structure, 1 is a floor panel, 2 is a floor carpet, 3 is a cover, 4 is an exhaust cover, 5 is a lid, 6 is a drive device, and 7 is a switch. Note that the arrow FR in the figure indicates the front side of the vehicle, and the arrow UP indicates the upper side of the vehicle.

Ventilation holes 11 and 21 are installed in the floor panel 1 and the floor carpet 2 so as to communicate between the inside and outside of the vehicle interior. The vents 11 and 21 are formed into a mesh structure.

The cover 3 is installed on the vehicle interior side of the floor carpet 2 so as to cover the installation area of the vents 11 and 21. The cover 3 is made of a stretchable material, and has an insertion/extraction opening 31 at a predetermined position through which an occupant's foot 10 or an article 20 can be inserted or removed.

The exhaust cover 4 is installed on the outside of the floor panel 1 so as to cover the installation area of the vent 11 in the floor panel 1. The exhaust cover 4 has an exhaust port 41 that opens rearward at the rear in the longitudinal direction of the vehicle.

The outside of the exhaust port 41 is a place where negative pressure is generated outside the exhaust cover 4 while the vehicle is running, or a place where the pressure is lower than in the passenger compartment.

The lid 5 is provided at the exhaust port 41 of the exhaust cover 4 so as to open or close the exhaust port 41.

The drive device 6 opens or closes the lid 5, and includes a wire 61, a motor 62, and the like.

One end of the wire 61 is attached to the free end side of the lid 5, and the other end of the wire 61 is connected to a motor 62.

The motor 62 opens the lid 5 by pulling the wire 61, and closes the lid 5 by pushing the wire 61.

The motor 62 rotates forward in response to the ON signal from the switch 7 to pull the wire 61 and open the lid 5, and rotates in the reverse direction in response to the OFF signal from the switch 7 to pull the wire 61 and open the lid 5. 61 is pressed to close the lid 5.

The switch 7 is manually turned on and off, and outputs an on signal when turned on, and outputs an off signal when turned off.

Although not shown, the switch 7 is installed near at least one of the passenger seat and the rear seat, for example.

Next, the operation will be explained.

For example, as shown in FIG. 1, in order to insert the foot 10 of an occupant between the cover 3 and the floor carpet 2, it is sufficient to insert the foot 10 through the insertion/extraction opening 31 of the cover 3. As a result, since the cover 3 has elasticity, the cover 3 stretches and swells.

In this state, even if the air inside the vehicle is cold, for example, the cold air does not come into direct contact with the feet 10, so the feet 10 can be prevented from becoming cold.

In addition, if an odor is generated from the occupant's feet 10, the cover 5 is opened by the drive device 6 by the occupant turning on the switch 7 to prevent the odor from drifting into the passenger compartment. For example, if the vehicle is running, or if heated air, cooled air, or air is introduced into the vehicle interior by an air conditioner (not shown) when the vehicle is stopped or running at low speed, the cover 3 and the floor carpet 2 are The air between them can be discharged to the outside of the passenger compartment from the exhaust port 41.

Note that when the vehicle is run as described above, negative pressure is generated outside the exhaust port 41 of the exhaust cover 3 due to the wind passing under the floor panel 1, and this negative pressure causes the cover 3 and the floor carpet to 2 is sucked and discharged to the outside of the vehicle through the vents 11, 21 and the exhaust port 41.

On the other hand, when the vehicle is stopped or running at low speed, if heating air, cooling air, or air is introduced into the interior of the blower by the vehicle's existing air conditioning equipment (not shown), the pressure inside the vehicle increases and the exhaust cover Since the pressure at the outside of the exhaust port 41 of No. 3 is lower than the pressure inside the vehicle interior, the air between the cover 3 and the floor carpet 2 is pushed out from the vents 11, 21 and the exhaust port 41 to the outside of the vehicle interior. become.

Further, as shown in FIG. 4, articles 20 can be stored between the cover 3 and the floor carpet 2.

If the article 20 is something that generates an odor, such as garbage or food or drink, the occupants should, in the same way as described above, prevent the odor emitted from the article 20 from drifting into the passenger compartment 14. By turning on the switch 7, the drive device 6 leaves the lid 5 in an open state, and for example, when the vehicle is running, or when the vehicle is stopped or running at low speed, the air conditioning equipment already installed in the vehicle (not shown) is used. By introducing heating air, cooling air, or blower air into the interior of the vehicle, the air between the cover 3 and the floor carpet 2 can be discharged from the exhaust port 41 to the outside of the vehicle interior.

If the inside of the vehicle is not cold and no odor is emitted from the occupant's feet 10 or the articles 20, the occupant's feet 10 are placed on the cover 3 as shown in FIG. Although not shown, the article 20 may be placed on the cover 3.

As explained above, according to the embodiment to which the present invention is applied, a space can be secured on the floor carpet 2 in the vehicle interior to cover the occupant's feet 10 and the articles 20, so that the cover 3 and the floor carpet 2 can be An occupant's feet 10 can be inserted between them.

Thereby, for example, when the air inside the vehicle is cold, it is possible to prevent the occupant's feet 10 from becoming cold by putting them between the cover 3 and the floor carpet 2.

In addition, when the occupant's feet 10 or articles 20 are placed between the cover 3 and the floor carpet 2 as described above, the exhaust cover 4 can be opened by opening the lid 5 and then driving the vehicle. Negative pressure is generated outside the exhaust port 41, or when the vehicle is stopped or running at low speed, heated air, cooled air, or blown air is introduced into the vehicle interior using the existing air conditioning equipment (not shown) installed in the vehicle. By increasing the pressure inside the vehicle interior, the air between the cover 3 and the floor carpet 2 can be efficiently discharged to the outside of the vehicle interior.

As a result, if an odor is emitted from the foot 10 or article 20 (garbage, food, etc.) inserted between the cover 3 and the floor carpet 2, a new ventilation equipment (not shown) can be installed inside the cover 3. This allows the odor to be discharged outside the vehicle interior, making it possible for the occupants to spend a comfortable time inside the vehicle interior.

Note that the present invention is not limited to the above-described embodiments, and can be modified as appropriate within the scope of the claims and within the scope equivalent to the claims.

(1) For example, FIGS. 5 and 6 show other embodiments of the present invention. In this embodiment, by providing two insertion/extraction ports 31A and 31B in the cover 3, the legs 10A and 10B of an occupant sitting on the front and rear seats (not shown) of the vehicle can be simultaneously inserted while the front and rear seats (not shown) are facing each other. It is designed so that it can be inserted between the cover 3 and the floor carpet 2.

The other configurations are basically the same as those of the embodiment shown in FIG. This embodiment also provides the same functions and effects as those of the above embodiment.

(2) For example, FIG. 7 shows another embodiment of the present invention. In this embodiment, a heater 8 is installed inside the cover 3.

The heater 8 can be, for example, a heating wire. According to this configuration, the space between the cover 3 and the floor carpet 2 is heated by activating the heater 8, so that if the occupant's feet 10 are inserted between the cover 3 and the floor carpet 2, the feet 10 will be warmed. becomes possible.

(3) In the above embodiment, an example is given in which the lid 5 is placed in an open state or a closed state in response to a human on/off operation of the switch 7, but the present invention is not limited to this. It's not something you can do.

For example, instead of the switch 7, although not shown, when the occupant's foot 10 or the article 20 is inserted between the cover 3 and the floor carpet 2, the occupant's foot 10 or the article 20 is detected and a detection signal is generated. A sensor outputs a non-detection signal when it does not detect the occupant's foot 10 or an article 20, or outputs a detection signal when it detects a bulge in the cover 3, but does not detect the bulge. It is possible to use a sensor that outputs a non-detection signal.

The operation when using such a sensor will be explained. First, the drive device 6 opens the lid 5 in response to a detection signal from the sensor. This makes it possible to exhaust the air between the cover 3 and the floor carpet 2 to the outside of the vehicle interior through the exhaust port 41.

On the other hand, the drive device 6 closes the lid 5 in response to the non-detection signal from the sensor. This prevents air from outside the vehicle interior from entering between the cover 3 and the floor carpet 2 through the exhaust port 41.

According to this configuration, the lid 5 can be automatically brought into an open state or a closed state using the sensor, so that the occupant does not have to operate a switch.

(4) In the above embodiment, an example is given in which the wire 61 of the drive device 6 is pushed and pulled by the motor 62, but the present invention is not limited to this.

For example, instead of the motor 62, it is possible to use a manual lever (not shown) to push and pull the wire 61. In this case, the wire 61 and the manual lever constitute the drive device 6.

For example, although not shown, it is possible to omit the wire 61 and use the motor 62 to directly bring the lid 5 into the open or closed state. In this case, the motor 62 constitutes the drive device 6.
