DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] The vehicle purification device according to this embodiment will be described with reference to Figures 1 to 4. Note that the same or corresponding components in the various drawings are denoted by the same reference numerals.

[0011] In the following, it is assumed that the vehicle purification device according to this embodiment is applied to a vehicle equipped with a parking brake lever. Also, the vehicle purification device according to this embodiment can be applied not only to engine vehicles, but also to electric vehicles, hybrid vehicles, fuel cell vehicles, and other types of vehicles.

[0012] Fig. 1 is a schematic diagram showing the positional relationship between a console box 3 and an ultraviolet ray irradiation unit 5 of a vehicle purification device 1 according to an embodiment of the present invention. For ease of explanation, many parts of the vehicle, such as doors, seats, and a steering wheel, are not shown in Fig. 1.

[0013] As shown in FIG. 1, the vehicle purification device 1 according to this embodiment includes a console box 3 extending in the fore-and-aft direction X of the vehicle between a driver's seat (not shown) and a passenger seat (not shown) of the vehicle, and an ultraviolet ray irradiation unit 5 provided in the vehicle cabin for irradiating ultraviolet rays UV onto a grip portion 103 of a parking brake lever 101.

[0014] Fig. 2(A) is a perspective view showing the console box 3 of the vehicle purification device 1 according to the embodiment of the present invention, and Fig. 2(B) is an enlarged view of the AA cross section of Fig. 2(A). In Fig. 2(B), the ultraviolet rays UV irradiated from the ultraviolet irradiating unit 5 are symmetrical with respect to the center line C1, but for ease of explanation, they are shown only on the left side of the paper with the center line C1 as the boundary. The same applies to Fig. 4.

[0015] As shown in Fig. 1 and Fig. 2(A) and Fig. 2(B), the console box 3 has a substantially rectangular parallelepiped shape. The front side of the console box 3 is fixed to an instrument panel 105. The bottom side of the console box 3 is fixed to a vehicle floor (not shown). The console box 3 has an opening 11 through which the parking brake lever 101 passes, and a recessed portion 13 that is disposed below the grip portion 103 of the parking brake lever 101 to avoid contact with the hand of a passenger gripping the grip portion 103 when the parking brake is released.

[0016] The opening 11 is provided behind the recessed portion 13 in the front-rear direction X of the vehicle. Also, the opening 11 is provided, for example, in the center of the width direction of the console box 3 that is parallel to the width direction Y of the vehicle. The shape of the opening 11 when viewed from above is usually approximately rectangular.

[0017] The recessed portion 13 is provided forward of the opening 11 in the front-rear direction X of the vehicle. The recessed portion 13 is provided, for example, in the center of the width of the console box 3 parallel to the width direction Y of the vehicle. The shape of the recessed portion 13 when viewed from above is usually approximately rectangular. The length dimension of the width of the recessed portion 13 parallel to the width of the console box 3 is greater than the length dimension of the width of the grip portion 103 parallel to the width of the console box 3. In the example of FIG. 2(B), a center line C1 that passes through the cross-sectional center of the grip portion 103 of the parking brake lever 101 and extends in the up-down direction passes through the center of the width of the recessed portion 13.

[0018] The ultraviolet ray irradiation unit 5 is provided on the ceiling 107. The ultraviolet ray irradiation unit 5 is usually provided on the ceiling 107 directly above the grip 103. More specifically, the ultraviolet ray irradiation unit 5 is provided at a location where the ultraviolet ray irradiation center line C of the ultraviolet ray irradiation unit 5 can intersect with the grip 103. However, the location of the ultraviolet ray irradiation unit 5 in the front-rear direction of the vehicle does not necessarily have to be directly above the grip 103, and it is sufficient that at least the entire grip 103 is included within the effective irradiation range R of the ultraviolet ray irradiation unit 5. The ultraviolet ray irradiation unit 5 irradiates ultraviolet rays UV to the upper half 103a, which is the upper surface of the grip 103, and the recessed portion 13, as shown in FIG. 2(B).

[0019] The upper half 103a of the grip portion 103 is the upper portion of the grip portion 103 with respect to a center line C2 that passes through the center of the cross section of the grip portion 103 of the parking brake lever 101 shown in FIG. On the other hand, the lower half 103b of the grip portion 103 is a portion below the center line C2.

[0020] The ultraviolet ray irradiation unit 5 includes one or more ultraviolet ray lamps (not shown). The type of ultraviolet ray lamp is, for example, a fluorescent tube such as a xenon lamp or a metal halide lamp, or an LED (Light Emitting Diode). From the viewpoint of sterilization ability, the wavelength of light emitted by the ultraviolet ray lamp is usually a value within a range of 200 nanometers (nm) to 300 nanometers (nm). Note that the ultraviolet ray irradiation unit 5 may, for example, increase the number of ultraviolet ray lamps to expand the effective irradiation range R, and irradiate ultraviolet ray UV to a wider area of ​​the vehicle interior including the parking brake lever 101.

[0021] FIG. 3 is a block diagram showing another configuration connected so as to be able to communicate with the ultraviolet irradiating section 5 of the vehicle purification device 1 according to the embodiment of the present invention.

[0022] 3, the vehicle purification device 1 according to this embodiment further includes a visible light emitter 31 that emits visible light, a detector 33 that detects various information related to the vehicle, and a controller 35 that controls the ultraviolet ray irradiator 5 and the visible light emitter 31. The ultraviolet ray irradiator 5, the visible light emitter 31, the detector 33, and the controller 35 are connected to be able to communicate with each other, that is, to be able to exchange information, via an in-vehicle network 37. The in-vehicle network 37 is a bus-type network that uses, for example, a controller area network (CAN) as a communication protocol.

[0023] The visible light emitter 31 includes one or more visible light sources. The type of the visible light source is, for example, an LED. The size of the visible light emitter 31 is smaller than that of the ultraviolet ray irradiation unit 5, and the aesthetic appearance is not marred even if the visible light emitter 31 is installed in a place that is easily noticeable to passengers.

[0024] The detection unit 33 includes a first detection unit 41 that detects the presence or absence of a passenger in the vehicle cabin, and a second detection unit 43 that detects the opening and closing of the vehicle door. The detection unit 33 outputs various data detected by the first detection unit 41 and the second detection unit 43 to the control unit 35.

[0025] The first detection unit 41 is, for example, an in-vehicle camera. The in-vehicle camera captures an image of the interior of the vehicle. The in-vehicle camera includes an image processing unit (not shown) that detects the presence or absence of an occupant in the interior from the captured image. The first detection unit 41 may also include a seating sensor in addition to the in-vehicle camera. The seating sensor is provided, for example, in each seat of the vehicle, and detects whether or not an occupant is seated in the seat by detecting the pressure on the seat surface of the seat.

[0026] The second detection unit 43 is, for example, a door sensor. The second detection unit 43 detects, for example, opening / closing, unlocking, locking, etc. of each door of the vehicle.

[0027] The control unit 35 turns on or off the ultraviolet irradiator 5 and the visible light emitter 31 based on the data output from the detection unit 33. In addition, the control unit 35 appropriately adjusts the irradiation intensity and irradiation time of the ultraviolet irradiator 5 and the emission intensity and irradiation time of the visible light emitter 31.

[0028] The control unit 35 can be configured as a computer equipped with a processor such as a CPU, a read only memory (ROM), a random access memory (RAM), and a storage device such as a hard disk drive (HDD). In this case, for example, the functions of the control unit 35 can be realized by the processor executing a predetermined program stored in the storage device. Also, instead of such software processing, the functions can be realized by hardware such as an application specific integrated circuit (ASIC) or a field programmable gate array (FPGA).

[0029] Incidentally, when ultraviolet rays UV are irradiated from the ultraviolet irradiating unit 5 provided on the ceiling 107 inside the vehicle, the upper half 103a (see FIG. 2(B)), which is the upper surface of the grip portion 103 of the parking brake lever 101, is a portion that is not in shadow (a portion that is not in a blind spot where the ultraviolet rays UV are not directly irradiated), that is, a portion that is directly irradiated with the ultraviolet rays UV. On the other hand, the lower half 103b (see FIG. 2(B)), which is the lower surface of the grip portion 103, is a portion that is in shadow, that is, a portion that is in a blind spot where the ultraviolet rays UV are not directly irradiated. Therefore, simply irradiating the lower half 103b of the grip portion 103 with ultraviolet rays UV from the ultraviolet irradiating unit 5 does not sterilize the lower half 103b of the grip portion 103 by sufficient direct irradiation of the ultraviolet rays UV.

[0030] Therefore, as shown in FIG. 2(B), the recessed portion 13 of the console box 3 has an ultraviolet ray reflecting portion 21 that has a recessed shape with the center in the width direction perpendicular to the front-rear direction of the vehicle recessed downward and reflects the irradiated ultraviolet ray UV to the lower half portion 103b of the grip portion 103. The ultraviolet ray reflecting portion 21 has a recessed center in the width direction perpendicular to the front-rear direction X of the vehicle recessed downward, and the grip portion 103 is located directly above this recess. In other words, the ultraviolet ray reflecting portion 21 is provided so as to partially surround the lower half portion 103b of the grip portion 103. Therefore, the ultraviolet ray reflecting portion 21 reflects the ultraviolet ray UV irradiated from the ultraviolet ray irradiating portion 5 to the recessed portion 13, and irradiates the ultraviolet ray UV to the lower half portion 103b of the grip portion 103. In other words, the vehicle purification device 1 sufficiently irradiates the lower surface of the parking brake lever 101 with the ultraviolet ray UV.

[0031] The recessed portion 13 of the console box 3 may also have a concave shape in which the center of the width direction of the recessed portion 13 perpendicular to the front-rear direction of the vehicle is recessed downward. In this case, the ultraviolet ray reflecting portion 21 follows the concave shape of the recessed portion 13, that is, the concave ultraviolet ray reflecting portion 21 is provided so as to overlap the surface of the concave recessed portion 13, and reflects ultraviolet rays UV to the lower half portion 103b of the grip portion 103. Furthermore, the position of the parking brake lever 101 when irradiated with ultraviolet rays is usually the position when the parking brake is applied. Furthermore, the time for the purification process of the vehicle purification device 1 that sterilizes the parking brake lever 101 by irradiating with ultraviolet rays is usually about several seconds per time.

[0032] FIG. 4 is a diagram showing the relationship between the inflection point P on the curved surface of the ultraviolet ray reflecting section 21 of the vehicle purification device 1 according to the embodiment of the present invention and the reflection of ultraviolet ray UV.

[0033] 4, the ultraviolet ray reflecting portion 21 may have a curved surface having at least one inflection point P that focuses reflected ultraviolet ray UV on the lower half portion 103b of the grip portion 103 at a location that reflects ultraviolet ray UV without being shaded by the grip portion 103, in other words, at a location that is directly irradiated with ultraviolet ray UV. This allows the vehicle purification device 1 to more reliably irradiate ultraviolet ray UV on the lower half portion 103b of the grip portion 103. The inflection point P will be further described below with reference to FIG. 4.

[0034] More specifically, the inflection point P changes the inclination of the surface of the ultraviolet ray reflecting portion 21 from the inflection point P on either side, and concentrates the ultraviolet ray UV on the lower half portion 103b compared to when the inclination of the surface of the ultraviolet ray reflecting portion 21 is constant.

[0035] The inflection point P determines a line segment LS1 indicating the inclination of the ultraviolet ray reflecting portion 21 with respect to the width direction of the ultraviolet ray reflecting portion 21 so that ultraviolet ray UV1 irradiated from the ultraviolet ray irradiating portion 5 and passing along the side of the grip portion 103 is reflected by the ultraviolet ray irradiating portion 5 and irradiated onto the lower end portion 103c of the grip portion 103. Furthermore, the inflection point P determines a line segment LS2 indicating the inclination of the ultraviolet ray reflecting portion 21 with respect to the width direction of the ultraviolet ray reflecting portion 21 so that ultraviolet ray UV2 irradiated from the ultraviolet ray irradiating portion 5 and hitting the vicinity of the end portion of the ultraviolet ray reflecting portion 21 is reflected and irradiated onto the side end portion 103d of the grip portion 103.

[0036] The line segments LS1 and LS2 have different inclinations with respect to the width direction of the ultraviolet ray reflecting portion 21. In particular, when the effective irradiation range R of the ultraviolet ray irradiation portion 5 in the width direction of the vehicle is narrow, by making the ultraviolet ray reflecting portion 21 have a curved surface having an inflection point P, ultraviolet rays UV can be sufficiently irradiated to the lower half portion 103b of the grip portion 103 and up to the vicinity of the side end portion 103d of the grip portion 103.

[0037] Moreover, it is preferable that the recessed portion 13 is made of resin and has a concave shape in which the center of the width direction of the recessed portion 13 perpendicular to the front-rear direction X of the vehicle is recessed downward. Furthermore, it is preferable that the ultraviolet ray reflecting portion 21 has an aluminum plating layer 21a or a chrome plating layer 21b laminated on the surface of the recessed portion 13. In general, aluminum plating or chrome plating has high reflection efficiency for ultraviolet rays. Therefore, the ultraviolet ray reflecting portion 21 having the aluminum plating layer 21a or the chrome plating layer 21b and having a concave shape following the shape of the recessed portion 13 efficiently reflects the ultraviolet rays UV from the ultraviolet ray irradiating portion 5. More preferably, if the plating layer is a vapor deposition layer, it can be easily provided in the recessed portion 13 of the console box 3 made of resin along the concave shape by a known method such as a vacuum deposition method or a sputtering method.

[0038] If the vehicle purification device 1 according to this embodiment executes the purification process while there is a passenger in the vehicle, the passenger may be exposed to ultraviolet rays UV. Ultraviolet rays may affect the human body depending on their wavelength, irradiation intensity, and irradiation time.

[0039] Therefore, when the first detection unit 41 detects that there is no passenger in the vehicle, it is preferable that the control unit 35 turns on the ultraviolet ray irradiation unit 5. In this way, the vehicle purification device 1 prevents the passenger from being exposed to ultraviolet rays UV. In other words, the vehicle purification device 1 prevents the control unit 35 from turning on the ultraviolet ray irradiation unit 5 when there is a passenger in the vehicle.

[0040] When the second detection unit 43 detects the door opening while the ultraviolet ray irradiation unit 5 is ON, the control unit 35 preferably turns OFF the ultraviolet ray irradiation unit 5. By doing so, the vehicle purification device 1 stops the purification process. Therefore, even if a person unexpectedly tries to get in while irradiating ultraviolet rays UV to purify the interior of the vehicle, the vehicle purification device 1 immediately turns OFF the ultraviolet ray irradiation unit 5 to prevent the passenger from being exposed to ultraviolet rays UV.

[0041] It is preferable that the control unit 35 also turns on the visible light emitter 31 when turning on the ultraviolet irradiator 5. In this way, the vehicle purification device 1 causes the visible light emitter 31 to emit light to visually inform passengers outside the vehicle that the purification process is in progress. Therefore, the vehicle purification device 1 prevents passengers from unexpectedly trying to get in the vehicle during the purification process.

[0042] It is preferable that the visible light emitter 31 can be seen from outside the vehicle through the front window 109 (see FIG. 1) and a side window (not shown). The visible light emitter 31 can be provided on the upper side of the instrument panel 105, for example.

[0043] As described above, the vehicle purification device 1 according to this embodiment includes a recessed portion 13 having an ultraviolet ray reflecting portion 21 that has a concave shape with a downward recess at the center in the width direction perpendicular to the front-rear direction X of the vehicle in the console box 3 and reflects the irradiated ultraviolet ray UV to the lower half portion 103b of the grip portion 103. Therefore, when the ultraviolet ray irradiating portion 5 is provided on the ceiling portion 107 inside the vehicle, the vehicle purification device 1 can irradiate sufficient ultraviolet ray UV not only to the upper half portion 103a that is the upper surface of the grip portion 103 of the parking brake lever 101, but also to the lower half portion 103b that is the lower surface of the grip portion 103.

[0044] Furthermore, the vehicle purification device 1 according to this embodiment includes an ultraviolet ray reflecting section 21 having a curved surface with at least one inflection point P that focuses reflected ultraviolet ray UV on the lower half section 103b of the grip section 103, at a location in the console box 3 where the ultraviolet ray UV is reflected without being shaded by the grip section 103 of the parking brake lever 101. Therefore, the vehicle purification device 1 can more reliably irradiate the ultraviolet ray UV on the lower half section 103b that is the underside of the grip section 103.

[0045] Furthermore, the vehicle purification device 1 according to this embodiment is made of resin, and is provided with a recessed portion 13 having a concave shape in which the center of the width direction of the recessed portion 13, which is perpendicular to the front-rear direction of the vehicle, is recessed downward, and an ultraviolet ray reflecting portion 21 having an aluminum plating layer 21a or a chrome plating layer 21b laminated on the surface of the recessed portion 13. Therefore, the vehicle purification device 1 can be provided with the ultraviolet ray reflecting portion 21 by the shape of the recessed portion 13 and surface treatment. Therefore, the vehicle purification device 1 does not require the addition of a new part such as a reflector as the ultraviolet ray reflecting portion 21, and an increase in costs can be suppressed.

[0046] Furthermore, the vehicle purification device 1 according to this embodiment includes a control unit 35 that turns on the ultraviolet ray irradiation unit 5 when the first detection unit 41 detects that no passengers are inside the vehicle. Therefore, the vehicle purification device 1 can prevent the ultraviolet ray irradiation unit 5 from being erroneously turned on when there is a passenger inside the vehicle.

[0047] Furthermore, the vehicle purification device 1 according to this embodiment includes a control unit 35 that turns off the ultraviolet ray irradiation unit 5 when the second detection unit 43 detects that the door is open while the ultraviolet ray irradiation unit 5 is ON. Therefore, the vehicle purification device 1 can immediately turn off the ultraviolet ray irradiation unit 5 even if a passenger unexpectedly tries to get into the vehicle while the vehicle is being purified by irradiating ultraviolet rays UV.

[0048] Furthermore, the vehicle purification device 1 according to this embodiment includes a control unit 35 that also turns on the visible light emitter 31 when the ultraviolet irradiator 5 is turned on. Therefore, while purifying the interior of the vehicle, the vehicle purification device 1 causes the visible light emitter 31 to emit visible light, making it easy to visually inform passengers outside the vehicle that purification is underway.

[0049] Therefore, according to the vehicle purification device 1 of this embodiment, the underside of the grip portion 103 of the parking brake lever 101 can also be sufficiently irradiated with ultraviolet rays UV.

[0050] Although some embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and their modifications are included in the scope and spirit of the invention, and are included in the scope of the invention and its equivalents described in the claims.
