    EJECTOR NOZZLE
    Context of the invention
    Field of the invention
    The present invention relates to an ejection nozzle member for ejecting compressed air to remove water droplets and the like adhering to a vehicle mounted optical device which is mounted on a vehicle.
    Description of Related Art
    Conventionally, for example, a device for removing foreign matter is known for removing water droplets or the like adhering to an external camera mounted on a vehicle, and for ensuring good visibility. In such a device for removing foreign matter, for example, as disclosed in international publication No. WO 2015/159,763, a nozzle unit and a high pressure air generation unit are connected by piping. The nozzle unit is integrally formed with a vehicle-mounted camera, and is equipped with a mounting console attached to a vehicle body or the like, and a nozzle from which high pressure air is ejected. In addition, the distal end of the nozzle is arranged to face a camera lens mounted on the vehicle. After the high pressure air generated by the high pressure air generation unit feeds the nozzle through the piping, the high pressure air is sprayed from the nozzle to the lens of the vehicle-mounted camera, whereby water droplets, dust and the like which adhere to the lens are blown out.
    Summary of the invention
    However, with the configuration of international publication n'WO 2015/159 763 above, when the high pressure air is ejected from the nozzle, the nozzle rises away from the camera mounted on the vehicle due to the pressure of the high pressure air passing through the air passage of the nozzle, and water droplets or the like which adhered to the surface of the vehicle-mounted camera or the nozzle unit enter the air passage from the space that appears between the two organs, and the droplets or the like move again through the air passage to the side of the lens and eventually adhere to it.
    A main object of the present invention is to provide an ejection nozzle member which is capable of ensuring sealing performance when compressed air is ejected, and reliably preventing water droplets, the dust and the like from entering an air exhaust unit.
    The present invention is characterized by an ejection nozzle member configured to eject compressed air relative to a lens surface of an optical device mounted on a vehicle, comprising:
    a cover member fixed to the optical device mounted on the vehicle and enclosing an air passage through which the compressed air flows;
    a pipe connection part provided on the cover member and configured to supply the air passage with compressed air; and an air ejection unit formed at one end of the cover member and communicating with the air passage, the air ejection unit being configured to eject the compressed air towards the lens surface ;
    wherein the air ejection unit is formed to have clearance between the air ejection unit and the lens surface in the cover member, a seal member is formed on the member cover along a border with the air ejection unit, and the seal member is formed inclined to one side of the air ejection unit.
    According to the present invention, the ejection nozzle member for ejecting compressed air to the lens surface of the vehicle-mounted optical device includes the cover member attached to the vehicle-mounted optical device, and the unit air ejection formed at the end of the cover member and communicating with the air passage thereby ejecting the compressed air towards the lens surface. Further, the seal member is formed on the cover member along the border with the air ejection unit, and the seal member is formed inclined toward the side of the unit. air ejection.
    Consequently, by fixing the cover member to the optical device mounted on the vehicle, and placing the seal member in abutment against the optical device mounted on the vehicle, when compressed air supplies the ejection unit d air while passing through the air passage and is ejected onto the lens surface, since the seal member, which is inclined towards the side of the air ejection unit, is pressed by the compressed air against the vehicle-mounted optical device, using compressed air, the seal member can be placed in more intimate contact with the vehicle-mounted optical device.
    As a result, for example, even in the case where the cover member rises in a direction away from the optical device mounted on the vehicle due to the pressure of the compressed air in the air ejection unit , the seal member is pressed in a direction in which the seal member comes into intimate contact with the optical device mounted on the vehicle. As a result, the stop state is reliably maintained, and the entry of water droplets, dust and the like into the interior of the air ejection unit through a space between the member nozzle nozzle and the vehicle-mounted optical device is reliably prevented.
    The above and other objects, features and advantages of the present invention will become more apparent upon reading the following description taken in conjunction with the accompanying drawings, in which a preferred embodiment of the present invention is shown by way of example illustrative.

    Description of preferred embodiments
    Initially, a description will be given of a camera mounted on a vehicle (optical device mounted on a vehicle) 12 to which is fixed an ejection nozzle member 10. As shown in FIG. 1, the camera mounted on a vehicle 12, for example , is a rear camera disposed near the center of a rear door R in a vehicle, and includes a box 14 in the form of a trunk having a substantially rectangular cross-sectional shape, and a camera 16 housed inside the box 14. A lens (lens surface) 20 of the camera 16 is provided so as to be exposed to the outside through a lens hole 18 which is formed on a rear end surface (first surface) 14a of the housing 14.
    In addition, in the vehicle-mounted camera 12, an end portion in the longitudinal direction (the direction of the arrows A and B) of the housing 14 is fixed relative to the rear door R, and the lens 20 of the camera 16 is turned backwards (in the direction of arrow A) projecting from the rear door R by a predetermined length. In addition, the ejection nozzle member 10 is mounted on an upper surface (second surface) 14b of the housing 14, which is substantially perpendicular to the rear end surface 14a on which the lens 20 is exposed to the outside. .
    Thereafter, the ejection nozzle member 10, which is fixed to the vehicle-mounted camera 12, will be described.
    As shown in Figures 1 to 3, the ejection nozzle member 10 is formed of an elastic material such as rubber or the like, and is mounted in a covering relationship on a portion of the camera mounted on vehicle 12 The ejection nozzle member 10 includes a cover member 22, a pair of retaining members 24a, 24b which protrude outward in a direction of width relative to the cover member 22, and an air ejection unit 26 formed on one end of the cover member 22 and through which compressed air is ejected.
    The cover member 22 is arranged, for example, so as to cover portions of the substantially planar and horizontal upper surface 14b and the rear end surface 14a of the vehicle-mounted camera 12, and bomb obliquely upwards so that the height of the cover member 22 gradually changes in the longitudinal direction (in the direction of the arrows A and B) thereof. In addition, the lower surface of the cover member 22 is placed in abutment against the upper surface 14b of the camera mounted on vehicle 12, which is of substantially planar shape.
    In addition, as shown in Figure 3, an air passage 28, which extends from one end to the other along the longitudinal direction (in the direction of the arrows A and B), is formed in the 'cover member 22. The air passage 28 is formed, for example, with a rectangular section, which is wide in a width direction (the direction of arrow C in Figure 2) perpendicular to the longitudinal direction.
    Furthermore, one end of the cover member 22 is formed at the uppermost location, and a tubular connecting pipe (pipe connecting part) 30 is connected to the first end. The connection pipe 30 is curved perpendicular to a location connected to the cover member 22. One end of the connection pipe 30 communicates with the air passage 28 inside the cover member 22, while that the piping 32 supplied with compressed air is connected to its other end which projects outwards.
    In addition, the compressed air supplies the air passage 28 from a source of compressed air supply, not illustrated, through the piping 32 and the connection pipe 30. In addition, once installed on the vehicle-mounted camera 12 , the other end of the cover member 22 is disposed at a lowest position.
    The retaining members 24a, 24b are in the form of a plate having a predetermined thickness, and are arranged respectively on external sides in the width direction (the direction of the arrow C) perpendicular to the longitudinal direction of the cover member. 22. The retaining members 24a, 24b are formed with L-shaped sections, which are curved at right angles downwards after passing in the width direction from sides of the cover member 22. In addition, when the cover member 22 is installed in abutment against the upper surface 14b of the vehicle-mounted camera 12, the pair of retaining members 24a, 24b is placed in abutment respectively against the lateral surfaces of the vehicle-mounted camera 12 , whereby the cover member 22 is retained in the direction of the width (the direction of the arrow C).
    The air ejection unit 26 is disposed on the other end of the cover member 22. Once installed on the vehicle-mounted camera 12, the air ejection unit 26 extends towards the rear end surface 14a of the housing 14, and one end of the air ejection unit 26 is oriented towards the opening of the lens hole 18. More specifically, the end of the ejection unit 26 extends towards the vicinity of an outer edge of the lens 20 (there is a clearance between the air ejection unit 26 and the lens 20) (see FIG. 2).
    Furthermore, as shown in Figure 3, the air passage 28 extending from the cover member 22 is formed in the interior of the air ejection unit 26, and an ejection hole 34 is formed at one of its ends as an opening of the air passage 28. In addition, in the air ejection unit 26, the air passage 28 is formed so as to be oriented directly to the rear end surface 14a of the vehicle-mounted camera 12, and as shown in Figure 4, on external sides in the direction of the width of the air passage 28, a pair of seal members 36a , 36b is provided, which abut against the rear end surface 14a of the vehicle-mounted camera 12.
    As shown in Figure 4, the members forming seals 36a, 36b, for example, are arranged in the direction of extension of the air passage 28 and the ejection hole 34. The members forming seals 36a, 36b extend in directions away from the air ejection unit 26, and more specifically, protrude downward, and are lip-shaped extending in directions leaning towards the center in the direction of the width of the passage of air 28. In other words, the joint members 36a, 36b are formed along a border between the air ejection unit 26 (cover member 22) and the air passage 28 In addition, the joint members 36a, 36b are in tapered shape which tapers towards their distal ends.
    In addition, the joint members 36a, 36b abut with respect to the rear end surface 14a of the vehicle-mounted camera 12 so that their distal ends are oriented inward mutually in the width direction.
    The ejection nozzle member 10 according to the embodiment of the present invention is configured essentially as described above. Thereafter, operations and effects of the ejection nozzle member 10 will be described.
    Initially, after an adhesion of water droplets, dust and the like on the lens 20 in the vehicle-mounted camera 12 has been confirmed, a source of compressed air supply (not shown) is operated based on a control signal coming from a control unit not illustrated or from an operation of an operator, and high pressure compressed air supplies the connection pipe 30 via the piping 32. The compressed air passes from the pipe connection 30 through the cover member 22 and the air passage 28 of the air ejection unit 26, and is ejected from the ejection hole 34 towards the lens 20 of the vehicle-mounted camera 12 whereby the compressed air blows away water droplets and the like which adhered to the lens 20.
    Consequently, since the members forming seals 36a, 36b are pressed towards the housing 14 (in the direction of the arrow D in FIG. 4) by the compressed air which flows through the air passage 28, the members forming seals 36a, 36b are held in more intimate contact relative to the housing 14, whereby the sealing ability is enhanced. Furthermore, even in the case where the air ejection unit 26 rises (upward) in a direction away from the housing 14 due to the high pressure compressed air flowing through the air passage 28, by the members forming lip-shaped seals 36a, 36b which are pressed towards the housing 14 by the pressing force of the compressed air and which deform in a vertical direction, the state of abutment of the members forming seals 36a, 36b is held reliably.
    Accordingly, along with preventing the leakage of compressed air to the outside of the air passage 28, water droplets, dust, and the like which have entered and remain between the surface of the vehicle-mounted camera 12 and the ejection nozzle member 10 are prevented from reliably entering the interior of the air passage 28.
    In the above manner, according to the present embodiment, in the ejection nozzle member 10 for eliminating water droplets and the like adhering to the lens 20 of the vehicle-mounted camera 12, the air passage 28 through which the compressed air flows is formed in the interior of the cover member 22 which is fixed to the vehicle-mounted camera 12, and in the air ejection unit 26 formed at the end of the cover member 22, the lip-shaped seal members 36a, 36b are formed on external sides of the air passage 28 in the width direction, and the seal members 36a, 36b are brought to tilt towards the side of the air passage 28 and the side of the housing 14, and are brought into abutment against the rear end surface 14a of the housing 14.
    Accordingly, when the compressed air feeds the air passage 28 and is ejected from the ejection hole 34, and the water droplets and the like adhering to the lens 20 of the vehicle-mounted camera 12 are removed by blowing, the seal members 36a, 36b are pressed towards the housing 14 by compressed air inside the air passage 28, whereby the seal members 36a, 36b can be brought into more intimate contact with the housing 14 and form a hermetic seal. Consequently, even in the case where the ejection nozzle member 10 rises away from the vehicle-mounted camera 12 by the pressure of the compressed air, the distal end sides of the seal members 36a, 36b are deformed so as to spread outward in the width direction while remaining in abutment against the rear end surface 14a of the housing 14, whereby the state of abutment relative to the housing 14 is maintained reliably, and the sealability is preserved.
    As a result, the members forming seals 36a, 36b of the ejection nozzle member 10 can be brought to abut at any time relative to the housing 14 of the camera mounted on vehicle 12, and even in the case where the member ejection nozzle 10 is slightly separated from the housing 14, an entry of water droplets, dust and the like occurring between the two members in the interior of the air passage 28 can be reliably prevented. In addition, a leakage of the compressed air in the air passage 28 towards the outside can also be prevented by means of the pair of seal members 36a, 36b.
    Consequently, after water droplets and the like adhering to the lens 20 have been removed by the compressed air, movement of such water droplets and the like which have entered the air passage 28 towards the side of the lens 20, and the water droplets adhering again to the lens 20, can be avoided.
    In addition, the ejection nozzle member 10 is fixed to the upper surface 14b of the vehicle-mounted camera 12, and by providing the air ejection unit 26, from which the compressed air is ejected, so as to extend towards the lens 20 of the rear end surface 14a, the amount of projection towards the rear side (in the direction of arrow A in FIG. 1) of the vehicle on which the camera mounted on vehicle 12 is mounted can be deleted. Consequently, no limitation is imposed on the space behind the vehicle, and efficient use of such space is made possible.
    Further, by constituting the ejection nozzle member 10 of elastic material, it is also capable of functioning as a protective member which covers portions of the upper surface 14b and of the rear end surface 14a of the mounted camera. on vehicle 12, and consequently, the ejection nozzle member 10 can be protected against contact with the camera mounted on vehicle 12.
    In addition, the members forming seals 36a, 36b in the air ejection unit 26 are not limited to the lip-shaped case as described above. For example, as with the seal members 52a, 52b of the ejection nozzle member 50 shown in Figure 5, the seal members may be formed with a semicircular section curved outward from a lower surface of the air ejection unit 26.
    In addition, according to the embodiment described above, a case has been described in which the vehicle-mounted camera 12 to which the ejection nozzle members 10, 50 are fixed is a rear camera provided on a rear portion of the vehicle.
    ίο
    However, the present invention is not limited to this feature. For example, the vehicle-mounted camera 12 can be a front camera provided on a front portion of the vehicle.
