[0009] Patent Document 2: Japanese Utility Model Registration No. 2558994
[0010] Patent Document 3: Japanese Patent Application Laid-Open No. 8-268232
[0011] Patent Document 4: Japanese Utility Model Application Laid-Open No. 5-24464
[0012] Patent Document 5: Japanese Utility Model Registration No. 2500186 Summary of the invention
[0013] When uniformly vibrating a window glass or the like to remove water drops or the like from the entire surface thereof as in the above-mentioned conventional technology, the structure scale of the vibration device becomes large and the power consumption also increases.
[0014] On the other hand, in general cars, when water droplets or dirt adhere to movable glass such as door glass that is raised or lowered relative to the door, the following method is adopted, that is, the driver or other users wipe it with a rag or the like, or raise or lower the movable glass to spread the water droplets or dirt attached to the glass surface through the water-removing molding.
[0015] However, wiping by hand is difficult to do while driving, and it is difficult to properly wipe an arbitrary range unless the work is performed from outside the vehicle.
[0016] Furthermore, when the strip is extended through the water-removing strip, water droplets and dirt cannot be removed fundamentally.
[0017] In order to cope with such a situation, a technology capable of efficiently removing deposits from specific locations such as glass using a relatively small-scale device structure is desired.
[0018] In view of the above-mentioned problems, an object of the present invention is to provide a device for removing deposits that can effectively remove deposits from a specific area of an exterior member of a vehicle.
[0019] The present invention solves the above-mentioned problems by the following solving means.
[0020] The invention involved in technical solution 1 is an attachment removal device that removes attachments attached to the exterior components of a vehicle body. The attachment removal device is characterized in that it includes: a vibration generating unit that generates vibrations; and a vibration transmitting unit that has a first surface and a second surface, the first surface being arranged opposite to the exterior component, the second surface being arranged inclined at an acute angle relative to the first surface, and the vibration generating unit being installed thereon. The vibration transmitting unit is formed to be softer than the exterior component and generates surface waves traveling in a specified direction on the exterior component.
[0021] Thus, by exciting the second surface inclined at an acute angle relative to the first surface arranged relative to the outer component through the vibration generating unit, a surface wave that travels with directionality along a specified direction of travel can be generated on the outer component, and an effective and local removal effect of attachments can be achieved at a specific portion of the outer component located in the direction of travel of the surface wave.
[0022] The invention according to claim 2 is characterized in that the device for removing deposits according to claim 1 further comprises a liquid retaining portion which is in contact with or adjacent to the vibration transmitting portion and which maintains the state in which the liquid is in contact with the surface of the exterior component.
[0023] Thus, the liquid held on the surface of the exterior member is blown in the traveling direction of the surface wave simultaneously with the generation of the surface wave to form a liquid flow, thereby promoting the effect of removing attached matter such as dirt.
[0024] In the attached matter removing device according to claim 1 , the invention according to claim 3 is characterized in that a part of the liquid is retained between the vibration transmitting part and the exterior member.
[0025] Therefore, since the liquid acts as a medium for transmitting vibration from the vibration transmission part to the outer component, there is no need to make the vibration transmission part close to the outer component. Therefore, even if the outer component is movable, it is possible to properly excite without hindering the movement of the outer component.
[0026] Based on the attachment removal device described in Technical Solution 2 or 3, the invention involved in Technical Solution 4 is characterized in that the exterior component is a transparent component arranged on the window portion of the vehicle body, and the vibration generating part, the vibration transmitting part, and the liquid retaining part are accommodated in a window frame portion arranged on the peripheral portion of the window portion.
[0027] Thus, by housing the components of the deposit removing device in the window frame, it is possible to obtain the effect of removing deposits from transparent members such as window glass without affecting the exterior design of the vehicle.
[0028] Based on the attachment removal device described in any one of Technical Solutions 2 to 4, the invention involved in Technical Solution 5 is characterized in that the transparent component is a door window that can be raised and lowered on the door of the vehicle body, and the liquid retaining portion is arranged on a water-removing strip arranged at the upper end of the door.
[0029] Thus, in rainy days or the like, water flowing along the surface of the door window to the water removing molding is retained by the liquid retaining portion, so that the above-mentioned effects can be obtained with a simple structure.
[0030] In addition, by raising and lowering the door window while the door window is vibrated, the effect of removing deposits can be obtained over a wide range of the door window.
[0031] Based on the attachment removal device described in any one of Technical Solutions 2 to 4, the invention involved in Technical Solution 6 is characterized in that the transparent component is a door window that can be raised and lowered on the door of the vehicle body, and the liquid retaining portion is arranged inside the window frame, which retains the edge of the door window when the door window is in a fully closed state.
[0032] Thus, water collected on a waterproof weather strip or the like generally provided on a window frame portion is retained by the liquid retaining portion, and the above-mentioned effect can be obtained with a simple structure.
[0033] In the invention according to claim 7 , the attached matter removing device according to claim 6 is characterized in that a flow path is provided for guiding the liquid from a portion of the window frame separated from the liquid retaining portion to the liquid retaining portion.
[0034] Thus, by supplying the liquid from a portion of the window frame other than the portion where the liquid retaining portion is provided, it is possible to prevent the liquid in the liquid retaining portion from being interrupted, and the above-mentioned effect can be reliably obtained.
[0035] Based on the attachment removal device described in any one of Technical Solutions 1 to 7, the invention involved in Technical Solution 8 is characterized in that the vibration transmission part is configured so that the direction of the generated surface wave is consistent with or close to the direction of the running wind flowing around the vehicle body during driving.
[0036] Thus, the effect of removing deposits can be further improved by the synergistic effect of the surface waves and the traveling wind respectively causing the deposits to flow.
[0037] In the attached matter removing device according to any one of claims 1 to 8, the invention according to claim 9 is characterized in that the vibration generating part has a piezoelectric element, and the vibration transmitting part is formed of a resin material softer than the exterior member.
[0038] Thereby, the above-mentioned effects can be appropriately obtained with a simple structure.
[0039] Effects of the Invention

[0110] The front combination lamp 90 is a lamp that is unitized by accommodating various lamp devices such as a headlamp, a clearance lamp, and a turn signal lamp in a common housing.
[0111] The front combination lamps 90 are arranged below the hood 50 and above the bumper front portion 80 at the front end portion of the vehicle.
[0112] The attached matter removing device 100 is a device that excites the front door glass 41 to generate a surface wave that travels with directivity.
[0113] Figure 2 This is a schematic cross-sectional view of the attached matter removing device according to the first embodiment.
[0114] The attached matter removing device 100 includes a vibration generating unit 110 and a vibration transmitting unit 120 .
[0115] The vibration generating unit 110 is a piezo-element formed by sandwiching a piezoelectric body 111 made of polycrystalline ferroelectric ceramics of lead zirconate titanate (PZT) between a pair of electrodes 113 .
[0116] The vibration generator 110 generates vibration by applying an AC voltage to the electrode 113 .
[0117] The vibration transmitting unit 120 is a member that transmits the vibration generated by the vibration generating unit 110 to the front door glass 41 and generates a surface wave that propagates along the surface of the front door glass 41 .
[0118] The vibration transmission portion 120 is formed in a block shape having a vibration excitation surface portion 121 , an outer surface portion 122 , an input surface portion 123 , and the like.
[0119] The vibration transmission part 120 is preferably a material that has little attenuation on the vibration transmitted from the vibration generating part 110 and is softer than the glass material constituting the front door glass 41. Therefore, the vibration transmission part 120 can be integrally formed of a resin material such as polyphenylene sulfide resin that is softer than the glass material.
[0120] The vibration excitation surface portion 121 is a substantially planar portion (the first surface referred to in the present invention) that is disposed to face the surface of the front door glass 41 with a small gap therebetween.
[0121] The distance between the excitation surface portion 121 and the front door glass 41 is set to a degree that water can be held therebetween by surface tension, for example.
[0122] The outer surface portion 122 is a surface portion on the opposite side to the vibration surface portion 121 , and is formed in a planar shape arranged substantially parallel to the vibration surface portion 121 .
[0123] The input surface portion 123 is a surface portion (the second surface referred to in the present invention) to which the vibration generating portion 110 is mounted and to which the vibration generated by the vibration generating portion 110 is input.
[0124] The input surface portion 123 is a flat surface portion provided in a region near one end of the outer surface portion 122 and inclined in a direction in which the thickness becomes thinner toward the edge side.
[0125] An angle θ formed between the excitation surface portion 121 and the input surface portion 123 is set to an acute angle.
[0126] Water W supplied from a water retaining member 130 described later exists between the vibration excitation surface portion 121 of the vibration transmitting portion 120 and the front door glass 41 .
[0127] In this state, when an AC voltage is applied to the vibration generating unit 110 to generate ultrasonic vibration, the vibration is transmitted to the front door glass 41 via the vibration transmitting unit 120 and the water W.
[0128] At this time, the front door glass 41 generates a vibration toward the side opposite to the input surface portion 123 on which the vibration transmission portion 120 is provided ( Figure 2 The left side of the figure shows a surface wave that travels in a directionally directionally.
[0129] It is preferable that the wavelength of the surface wave is smaller than the thickness of the front door glass 41 , for example.
[0130] Figure 3 yes Figure 1 A schematic cross-sectional view taken along line III-III.
[0131] The attached matter removing device 100 is disposed in a region between the upper outer panel of the front door 40 and the front door glass 41 and adjacent to the water-removing molding M so that the propagation direction of the surface wave faces upward.
[0132] The water-removing molding M is a member disposed along the upper end portion of the outer panel of the front door 40 , and includes a lip portion formed of a flexible and elastic material such as rubber.
[0133] In addition, a water retaining member 130 is provided between the water removal molding M and the front door glass 41 and above the attached matter removing device 100 .
[0134] The water retaining member 130 includes, for example, a hair-planted portion and is a liquid retaining portion having a function of retaining water flowing down along the surface of the front door glass 41 in a state of contact with the surface of the front door glass 41 .
[0135] In addition, part of the water retained in the water retaining member 130 flows down to the attached matter removing device 100 side directly thereunder, and is supplied between the excitation surface portion 121 of the vibration transmitting portion 120 and the surface of the front door glass 41 .
[0136] In the first embodiment, when the vibration generating unit 110 generates ultrasonic vibrations while the water retaining member 130 sufficiently retains water, surface waves traveling upward are generated on the front door glass 41 , and water W is ejected upward along the surface of the front door glass 41 by the surface waves.
[0137] In addition, part of the water is atomized by the ultrasonic vibration and is scattered by the wind of the vehicle.
[0138] The flow of water W sprayed along the front door glass 41 cleans and removes water droplets, dirt and other attachments attached to a portion of the front door glass 41 (for example, an area behind the rearview mirror 43 and corresponding to the driver's visual field of the door rearview mirror 43).
[0139] The energization (excitation) of such a vibration generating unit 110 can be set to a structure that is turned on and off according to the driver's operation, for example. In addition, it can also be set to a structure that is energized when bad weather conditions such as rain or snow are detected or in conjunction with the driver's opening operation of the wiper device.
[0140] According to the first embodiment described above, the following effects can be obtained.
[0141] (1) A vibration generating portion 110 having a piezoelectric body is used to excite a vibration transmitting portion 120 having an excitation surface portion 121 and an input surface portion 123 forming a predetermined acute angle θ. This can generate a surface wave that travels in a directed manner along a predetermined direction of travel on a front door glass 41 that is an exterior component, and can effectively and locally remove deposits at a specific portion of the exterior component located in the direction of travel of the surface wave.
[0142] (2) By providing the water retaining member 130 adjacent to the vibration generating portion 110 and the vibration transmitting portion 120, the water W retained on the surface of the front door glass 41 is blown away in the direction of travel while generating surface waves to form a water flow, thereby promoting the removal of attached objects such as dirt.
[0143] (3) A portion of the water W is retained between the vibration transmission portion 120 and the front door glass 41, and the water W acts as a medium for transmitting the vibration from the vibration transmission portion 120 to the front door glass 41. Therefore, it is not necessary to make the vibration transmission portion 120 and the front door glass 41 in close contact. Therefore, even if the front door glass 41 is a movable glass of a lifting type, it can be properly excited without hindering its movement.
[0144] (4) By housing the vibration generating part 110, the vibration transmitting part 120, and the water retaining member 130 inside the water removal molding M provided at the peripheral edge of the front door glass 41, the effect of removing deposits from the front door glass 41 can be achieved without affecting the exterior design of the vehicle.
[0145] (5) By providing the water retaining member 130 adjacent to the water removal molding M, water W flowing along the surface of the front door glass 41 to the water removal molding M on rainy days is retained by the water retaining member 130, and the above-mentioned effect can be obtained with a simple structure.
[0146] Furthermore, by moving the front door glass 41 up and down while being vibrated, it is possible to obtain the effect of removing deposits over a wide range.
[0147] (6) The vibration generating unit 110 includes the piezoelectric element, and the vibration transmitting unit 120 is formed of polyphenylene sulfide resin. Thus, the above-mentioned effects can be appropriately obtained with a simple structure.
[0148] <Second embodiment>
[0149] Next, a second embodiment of the attached matter removing device to which the present invention is applied will be described.
[0150] In each embodiment described below, the same reference numerals are given to the same parts as those in the conventional embodiment, and the description thereof is omitted, and mainly the different points are described.
[0151] Figure 4 This is a schematic side view of the periphery of a front door glass of a vehicle equipped with the attached matter removing device according to the second embodiment.
[0152] In the second embodiment, a plurality of attached matter removing devices 100 are dispersedly arranged along the longitudinal direction of the door sash 42 .
[0153] In addition, the water retaining member 130 is continuously formed over the region where the plurality of attached matter removing devices 100 are installed.
[0154] Each of the attached matter removing devices 100 is arranged so that the traveling direction of the surface wave faces the rear side of the vehicle (along the traveling direction of the so-called traveling wind in which the surrounding air flows relative to the vehicle body when the vehicle is traveling).
[0155] A water guide channel (not shown) is formed inside the door sash 42 , and guides water captured in a region other than the region where the water retaining member 130 is provided toward the water retaining member 130 along the longitudinal direction of the door sash 42 .
[0156] According to the second embodiment described above, in addition to the same effects as those of the first embodiment (except the effects described in (4) and (5)), the following effects can be obtained.
[0157] (1) By providing the attached matter removing device 100 etc. on the door sash 42, the water collected on the waterproof weather strip etc. usually provided on the door sash 42 is retained by the water retaining member 130, thereby achieving the above-mentioned effects with a simple structure.
[0158] (2) By supplying water from a portion of the door sash 42 other than the portion where the water retaining member 130 is provided, it is possible to prevent the water retaining member 130 from being cut off, and thus the above-mentioned effect can be reliably obtained.
[0159] (3) By making the traveling direction of the surface wave of the deposit removal device 100 substantially coincide with the direction of the traveling wind, the deposit removal effect can be further improved by the synergistic effect of the surface wave and the traveling wind respectively causing the deposit to flow.
[0160] <Third embodiment>
[0161] Next, a third embodiment of the attached matter removal device to which the present invention is applied will be described.
[0162] Figure 5 This is a schematic perspective view of the appearance of the A-pillar and surrounding areas of a vehicle equipped with the attached matter removal device according to the third embodiment.
[0163] The attached matter removing device of the third embodiment has the same structure as the second embodiment described above, and further includes a water conduit 140 described below.
[0164] The water guide channel 140 is provided inside the A-pillar 20 , and guides water wiped onto the side end 13 of the windshield 10 by a wiper device (not shown), for example, to the water retaining member 130 provided in the door sash 42 .
[0165] According to the third embodiment described above, in addition to the same effects as the second embodiment, water scraped against the side end 13 of the windshield 10 can be supplied to the water retaining member 130 , thereby more reliably preventing the water retaining member 130 from being cut off.
