Further, when the occupant sucks a cold air component or a warm air component as an air quality component when it is cold or hot, it can locally obtain a heating effect or a cooling effect. In addition, as other air quality components, when it is configured to volatilize skin lotion or the like and contain it in an air cannon, it releases skin moisturizing as well as the humidity component, and is effective for passenger health and beauty. It will be.

  In addition, the housing | casing which comprises the air gun generators 10, 11, and 12 for vehicles is formed in flat shape, Narrow space, such as in the instrument panel 70, the overhead module 9, and the ceiling part of the vehicle interior 2, etc. It is possible to arrange

  Next, the internal configuration of the vehicle air cannon generator will be described. As shown in FIG. 3, the air gun generator for a vehicle has an air gun discharge port 27 on one end face in the housing 16A, and the air quality component chamber communicates with the discharge port 27 in the housing 16A. 15A, and air compression means 14A for compressing and reducing the volume of the air quality component chamber 15A on the other side.

  This air quality component chamber 15A is a space in which a predetermined air quality component generated in the component storage unit 17 passes through the opened valve 18 and is sent and stored by the transfer pump 19 via the connecting tube 20, and is transferred It is connected so as to communicate with the means 21. The air quality component transported by the transport means 21 is sent into the air quality component chamber 15A in a volatile state, and is filled in this volume. When the air quality component chamber 15A is filled with the air quality component more than necessary, the excess air quality component is discharged from the discharge port 27 to the outside. However, after the excess air quality component leaks, no further air quality component leaks immediately, and an appropriate amount of air quality component is retained in the air quality component chamber 15A.

  On the other hand, the air compression means 14A includes a compression member 40 that changes the volume of the air quality component chamber 15A by a magnetic force and an electromagnetic force, changes the volume of the air quality component chamber 15A, a magnet 41 provided in the compression member 40, and a compression The coil 42 is provided to face the member 40.

  When a voltage is applied to the air compressing means 14A from a vehicle-mounted battery or the like, an electromagnetic force is generated that causes a current to flow through the coil 42 and pushes the compression member 40 toward the air quality component chamber 15A. Further, a repulsive force is also exerted by the magnet 41, and a force for deforming the compression member 40 is exerted by the action of these electromagnetic force and magnetic force, so that the compression member 40 instantaneously acts on the air quality component chamber 15A side. Deforms greatly. At this time, the compression member 40 protrudes to the air quality component chamber 15A side up to a position 43 in a shape with its central portion protruding greatly, and the magnet 41 is also integrated with the compression member 40 to the air quality component chamber 15A side to the position 44. It will overhang. Due to the deformation of the compression member 40, the volume of the air quality component chamber 15A is instantaneously reduced, so that the air quality component filled in the volume is compressed and instantaneously discharged from the discharge port 27 to the outside. It will be. By causing this series of operations to occur instantaneously, air containing air quality components discharged from the discharge port 27 is discharged into the vehicle 2 as a fluid mass, for example, a vortex ring or a spherical mass.

  FIG. 4 is a perspective view showing the internal configuration of the housing 16A. The air quality component chamber 15A and the air compression means 14A are partitioned by a thin plate-shaped compression member 40. FIG. A coil 42 is arranged around the magnet 41 so as to surround it. The magnet 41 and the coil 42 are insulated by a resin member formed in a tubular shape. A cylindrical magnet 41 is arranged along the inner diameter of the resin member, and the magnet 41 slides on the inner diameter portion of the resin member along with the deformation of the compression member 40 due to electromagnetic force and magnetic force.

  The compression member 40 is composed of a plate-like member having a self-returning force, and is preferably composed of a thin plate such as rubber, silicon, or elastomer. By forming with these materials, the operating noise of the compression member can be reduced.

  The magnet 41 may be fixed to the compression member 40 by adhesion, or may be embedded in the compression member 40 and integrated. The coil 42 is arranged with a distance that does not contact the compression member 40 in a state where the compression member 40 is not deformed. The distance from the surface of the compression member 40 to the end surface of the housing 16A is as follows. It is desirable to configure the distance as small as possible to accommodate the magnet 41 as much as possible.

  As described above, in the configuration of the air compression means 14A, the magnet 41 is moved together with the compression member 40, so that a movable structure having excellent durability against repeated reciprocating motion can be obtained.

  The vehicular air cannon generator configured as described above is controlled by the configuration shown in FIG. The vehicle air cannon generator 13 is controlled based on various signals by an air quality component supply ECU 101 as a control means. The air quality component supply ECU 101 performs various analyzes on the signals from the navigation ECU 110, the vehicle integrated ECU 120, and / or the operation means 115, the timing when the air gun is released, and the amount of the air quality component contained in the air gun. Judgment of the release, such as the release speed of the air cannon.

  The air quality component supply ECU 101 controls the vehicle air gun generator 13 based on this determination. This control includes, for example, control of the amount of air quality component generated by the component storage unit 17, adjustment control of the opening degree of the valve 18 constituting the conveying means 21 for sending the air quality component to the air quality component chamber 15, and valve 18 The air quality stored in the air quality component chamber 15 is configured in the housing 16 together with the air quality component chamber 15, the control of the transfer pump 19 that is connected via the connecting tube 20 and creates the driving force of the transfer means 21. Control of the air compression means 14 which compresses the components and pushes them out from the outlet 27.

  The air quality component supply ECU 101 controls the compression of the air in the air quality component chamber 15 and the activation of the compression force with respect to the air compression means 14 of the vehicle air gun generator 13. For example, by controlling the magnitude of the compression force, it is controlled to which occupant the air cannon is released and how far the air cannon is delivered, and by controlling the activation of the compression force, the air cannon is continuously operated It is possible to control whether it is released periodically or intermittently with a predetermined time interval. Also, as shown in FIG. 1, when a plurality of vehicle air gun generators are arranged in the vehicle interior 2, which vehicle air gun generator is activated, or a plurality of vehicle air gun generators are installed. It is possible to control whether to start simultaneously.

  The navigation ECU 110 is a control unit of the navigation system, and provides at least basic functions of current position display, destination selection, route calculation, and route guidance to the occupant, and VICS (Vehicle Information and Communication System (road traffic information communication system). , A registered trademark of the Road Traffic Information Communication System Center), G-BOOK (content service available from in-vehicle devices, registered trademark of Toyota Motor Corporation), and external information such as the Internet It also has a function.

  When the navigation ECU 110 obtains that the road is congested by VICS or G-BOOK, the navigation ECU 110 transmits the information to the air quality component supply ECU 101. In response to this, the air quality component supply ECU 101 assumes that the occupant, in particular, the driver is sleepy, and supplies the air quality component with the fragrance component, oxygen component, or cold air component previously charged in the component storage unit 17 as the air quality component. It is sent to the component chamber and contained in the air cannon and discharged toward the driver. As a result, the driver can eliminate drowsiness by inhaling these components from the nose, obtain a wakefulness effect, and can prevent drowsy driving.

  Further, when the air quality component supply ECU 101 obtains traffic jam information from the navigation ECU 110, the air quality component supply ECU 101 assumes that the driver and other passengers are frustrated due to traffic jam and fills the component storage unit 17 in advance as an air quality component. Driver and other occupants are controlled by sending the fragrance, aroma, or ionic components from the component storage unit into the air quality component chamber and letting them into the air cannon and releasing them to the driver. Can make you feel relaxed.

  The vehicle integrated ECU 120 has a function of acquiring operation information of each functional component of the vehicle and communicating with the air quality component supply ECU 101. The operation information of each functional component includes, for example, vehicle speed information, brake information, inter-vehicle sensor information, window opening / closing information, and the like. The vehicle integrated ECU 120 transmits these pieces of information to the air quality component supply ECU 101. The air quality component supply ECU 101 recognizes information such as when the vehicle speed is equal to or lower than a predetermined value, the number of times of braking per unit time is equal to or higher than the predetermined value, or when the distance from the preceding vehicle by the inter-vehicle sensor is equal to or lower than the predetermined value. When it does, it is considered that there is a traffic jam, and as described above, it contains the aromatic component, oxygen component, or cold air component that has been filled in the component storage unit 17 in advance as an air quality component in order to supply the awakening effect In order to control the release of the air cannon to the driver or to provide a relaxing effect, the component storage unit 17 was previously filled with the aromatic component, aroma component, and ionic component as an air quality component. For example, the air gun is controlled to be released toward the driver.

  Further, when the vehicle integrated ECU 120 continuously obtains, for example, a value of 80 km or more as the vehicle speed information for a predetermined time or more, the air quality component supply ECU 101 assumes that the vehicle is traveling on a highway or the like and falls asleep. In order to prevent driving, the aroma component, oxygen component, or cold component, which has been filled in the component storage unit 17 in advance as an air quality component, is sent to the air quality component chamber in a predetermined amount, and is supplied to the air cannon. It is contained and released to the driver.

  Further, when the vehicle integrated ECU 120 transmits to the air quality component supply ECU 101 that the window is opened as the window opening / closing information, the air quality component supply ECU 101 recognizes that the outside wind is blowing into the vehicle, and is predetermined. Interlock control is performed to stop the release of the air cannon until information is obtained that the time or window is closed. When the window is open, the outside wind is flying in the car 2. Therefore, even if the air cannon is released, it is difficult to diffuse the air cannon toward a predetermined occupant or space. Is.

  This operating means 115 is for forcibly starting the vehicle air cannon generator when the occupant himself wants to obtain a humidity component. For example, the occupant of the instrument panel 70 is easy to operate. The place is configured in the form of a switch or button. The operation means 115 activates the vehicle air quality component supply device 13, controls the magnitude of the compression force for compressing the air in the air quality component chamber 15, and releases an air cannon toward any space in the vehicle 2 or to any occupant. Means for instructing to control whether to

  By configuring the vehicle air cannon generating apparatus in this way, the physique of the housing 16 can be formed very small. For example, the longitudinal length L1 of the air quality component chamber 15 and the air compression means 15 is approximately 50 mm, the longitudinal length Z1 of the air quality component chamber is approximately 30 mm, and the longitudinal dimension X1 of the housing is approximately 30 mm. The diameter Y1 of the discharge port 27 can be formed to be about φ8 to 10 mm. Further, as shown in FIG. 5, the shape of the housing may be a cylindrical housing 80. In this case, the outer diameter R2 of the cylinder is approximately φ30 mm, and the inner diameter R1 of the discharge port can be configured to be about 1/3 of the outer diameter R2, and thus is formed to be approximately φ10 mm.

  The material of the housing is not particularly limited, but is made of a material that can maintain a certain degree of airtightness such as resin and metal so that the air quality component filled in the air quality component chamber 15 does not leak.

  The component storage unit 17 includes a component supply unit and a heating unit that volatilizes the component supplied by the component supply unit, and may be provided in the air quality component supply chamber 15. When the component storage unit 17 is configured integrally with the housing 16 as described above, the component storage unit is separately provided as compared with the configuration in which the component storage unit 17 is connected to the housing 16 through the conveying means 21 as shown in FIG. There is no need to provide a casing for forming the apparatus 17, and the apparatus can be reduced in size. This component supply means may be constituted by a tube, and the component may be sent from the outside through the tube. The heating means is a heater that immediately heats the component that has flowed out of the tube, and can vaporize the component and allow the air in the air quality component chamber to contain the component.

  The voltage applied to the air compressing means 14 is a rectangular wave voltage as shown in FIG. 6 by ON / OFF control. By applying a rectangular wave voltage instead of a parabolic waveform voltage, an electric current is instantaneously passed through the coil 24, an electromagnetic force is generated in a short time, and the compression member 22 is deformed instantaneously. be able to. The rectangular wave is a voltage having a width of about 1 second, and this voltage is applied a plurality of times at intervals of about several seconds. By applying such a voltage application method, a plurality of air cannons are continuously released to the occupant, so even if there are some obstacles on the way, any one air cannon By hitting the occupant, the probability that the occupant senses a predetermined air quality component can be improved.

  The voltage to be applied may be a 12V voltage, for example, by being supplied from a vehicle-mounted battery. Further, as shown in FIG. 7, a booster circuit using a capacitor may be used in order to enhance the voltage applied to the air compression means 14. For example, by boosting the applied voltage from 12V to 16V by a booster circuit, it is possible to increase the transport distance of the air cannon, and to provide a vehicular air cannon generator that allows a wider range of options for passengers who want to supply the air cannon .

  Next, a configuration in the case where the casing 16 and the component storage unit 17 of the vehicle air gun generator 16 are installed at a location separated from the interior 2 of the vehicle by the conveying means 21 will be described.

  When the casing 16 for releasing the air cannon toward the occupant 3 sitting in the front seat 5 is arranged on the ceiling above the front seat, the component storage unit 17 extends from the front seat side ceiling in the vehicle 2 The casing 16 is communicated with the casing 16 through the transporting means 21 and is disposed in the instrument panel 70. In addition, when the casing 16 that discharges the air gun toward the occupant 4 sitting in the rear seat 6 is disposed on the ceiling portion above the rear seat, the component storage portion extends from the rear seat side ceiling portion in the vehicle 2. It is configured to communicate with the casing 16 through the transporting means 21 and to be disposed in the trunk or in the rear seat tray.

  When the casing 16 that discharges the air cannon toward the occupant 3 sitting in the front seat 5 is disposed in the overhead module 9 above the front seat, the component storage unit 17 is provided on the front seat side ceiling of the vehicle interior 2. The casing 16 is communicated with the casing 16 via the conveying means 21 extending from the section, and is arranged in the instrument panel 70.

  When the housing 16 is disposed in the instrument panel 70, the component storage unit 17 communicates with the housing 16 via the transport means 21 to provide a glove box portion beside the instrument panel 70 or a center cluster. The configuration is arranged on the side.

As described above, according to the present embodiment, the air quality component chambers 15 and 15A holding predetermined components, and the air compression means for compressing the air in the air quality component chambers 15 and 15A and releasing the air cannon into the vehicle interior 2 14 and 14A are provided in the casings 16 and 16A,
The air compression means 14, 14 </ b> A are provided to oppose the compression member 40 that changes the volume of the air quality component chambers 15, 15 </ b> A by magnetic force and electromagnetic force, a magnet 41 provided in the compression member 40, and the compression member 40. Since the coil 42 is configured, the volume occupied by the air compression means can be reduced by using both the magnetic force and the electromagnetic force as the driving force for compression. It is possible to reduce the size of an air gun generator for a vehicle in which the installation space is limited.

  Further, when the compression member 22 is composed of a plate-like member having a self-returning force, the apparatus can be further downsized.

  Further, when the casing 16 is formed in a flat shape, it is useful for a vehicle having a limited installation space, and further, a narrow place closer to the occupant, for example, in an instrument panel, an overhead module, Alternatively, since the device can be arranged in a place such as a ceiling portion, the air cannon can be effectively discharged toward the occupant.

  Moreover, when the housing | casing 16 is formed in a column shape, since an installation place is not limited as a vehicle apparatus with a limited installation space, it is useful. In addition, the apparatus can be arranged in a narrow place closer to the occupant, for example, in an instrument panel, an overhead module, or a ceiling.

  Further, when the electromagnetic force of the air compressing means 14 is generated by an applied voltage having a rectangular wave shape, the electromagnetic force is instantaneously generated by applying an applied voltage having a protruding waveform. The air in the chamber is compressed instantaneously, and the generation of the air cannon can be promoted.

  In addition, when the applied voltage of the rectangular wave is applied by a booster circuit using a capacitor, the transfer distance of the air gun can be adjusted by boosting the applied voltage by the booster circuit. The air cannon can be appropriately released.

  In addition, the air cannon in a state in which a predetermined air quality component that can improve the comfort of the occupant is retained is supplied to the individual occupants 3, 4 from the instrument panel 70, the overhead module 9, or a device provided on the ceiling. In the case where the occupant senses by diffusing the predetermined air quality component to the occupant, the air cannon is directed toward an individual occupant anywhere in the vehicle interior space. Can be provided.

  Further, the air quality component chamber 15 and the air compression means 14 provided in the housing 16 are provided in the instrument panel 70, the overhead module 9, or the ceiling, and the transport means 21 and the component storage part 17 If the vehicle air cannon generator is divided into two parts, the air quality component chamber and the air compression means can be arranged in a narrow space. The air cannon can be released more effectively toward individual occupants.

  The component storage unit 17 includes a component supply unit and a heating unit that volatilizes the component supplied by the component supply unit. When the component storage unit 17 is provided in the air quality component chamber 15, By integrating the air quality component chamber and the air compressing means for discharging the air with the component storage unit, the entire vehicle air cannon generator can be reduced in size.

  In addition, when the component storage unit 17 is configured to be connected to the air quality component chamber 15 by the conveying means 21, the component storage unit 17 is configured not to be integrated with the air quality component chamber 15, thereby The mass component chamber 15 and the air compressing means 14 can each be arranged in a narrow space in the vehicle interior 2. Moreover, when the component storage part 17 is provided in the comparatively wide space in a vehicle, the capability of the component storage part 17 can be enlarged and air quality component supply capability can be improved.

  Further, when the air gun is configured to be released based on a signal from the navigation ECU 110 or a signal from the vehicle integrated ECU 120, the air cannon is supplied with necessary components that are directly adapted to the environment surrounding the occupant. An air cannon generator for a vehicle that can perform the above is obtained.

  Moreover, since it was set as the structure which arrange | positions the housing | casing 16 and the component storage part 17 in the position away via the conveyance means 21, while being able to discharge | release an air gun toward a passenger | crew from the appropriate position in a vehicle, An air quality component supply capability can be improved by enlarging a storage part or providing two or more.
