  As shown in FIG. 2, the camera 10 of the present embodiment includes a base portion 11 fixed to a camera fixing portion Pa of a vehicle body P (body panel), and a substantially cubic housing 12 fixed to the base portion 11. have. A circular imaging surface 13 is formed on the front surface of the housing 12 so that an internal imaging device faces through a lens (both not shown). The camera fixing portion Pa of the vehicle body P is inclined such that the fixing surface to which the camera 10 is fixed is directed to the rear lower side of the vehicle body, and the housing 12 of the camera 10 fixed to the camera fixing portion Pa has a front imaging. The surface 13 is inclined so as to image the rear lower part. Thereby, the upper surface of the housing 12 is a downward slope surface 14 that is inclined downward in the vertical direction toward the front surface (imaging surface 13).

  On the rear part of the vehicle body P, an in-vehicle camera washer nozzle (camera nozzle) 20 that discharges the cleaning liquid W to remove foreign matters such as raindrops and mud adhering to the imaging surface 13 of the camera 10 is provided. The camera nozzle 20 is spaced apart from the camera 10 upward.

  As shown in FIGS. 2 and 3, the camera nozzle 20 is configured by assembling a first member 21 and a second member 22. The first member 21 includes a base portion 23 fixed in contact with the nozzle fixing portion Pb of the vehicle body P, and a nozzle lower surface portion 24 extending from the center in the vehicle width direction of the base portion 23 to the side opposite to the vehicle body (the vehicle rear side). Have. The base portion 23 has one insertion hole 23a at the center in the vehicle width direction, and screw insertion holes 23b on both sides in the vehicle width direction of the insertion hole 23a. The nozzle fixing part Pb of the vehicle body P is substantially parallel to the camera fixing part Pa.

  The nozzle lower surface portion 24 extends from a lower portion of the insertion hole 23 a of the base portion 23, and the dimension in the vehicle width direction of the base portion is formed larger than the insertion hole 23 a of the base portion 23. The nozzle lower surface portion 24 is formed in a substantially U-shaped cross section from a bottom surface portion 24a and a side surface portion 24b extending substantially perpendicularly upward from both edges in the vehicle width direction of the bottom surface portion 24a. The tip portion of the base portion extending from 23 extends in the vehicle width direction. A pair of rectifying portions 24c protruding in the same direction as the side surface portion 24b is formed on the bottom surface portion 24a. Each rectification part 24c is formed in a narrow shape along the extending direction of the nozzle lower surface part 24, and is formed so as to be narrower in the vehicle width direction toward the root side of the nozzle lower surface part 24.

  The second member 22 is assembled from the vehicle rear side so as to sandwich the first member 21 with respect to the vehicle body P. The second member 22 is fixed to the base portion 23 of the first member 21, and the vehicle of the fixed portion 25. It is composed of a substantially cylindrical connecting tube portion 26 (connecting port) extending from the center in the width direction to the vehicle body P side, and a nozzle upper surface portion 27 extending from the center in the vehicle width direction of the fixed portion 25 to the side opposite to the vehicle body.

  The fixing portion 25 is in close contact with the base portion 23 of the first member 21 and has screw insertion holes 25a at positions on both sides of the nozzle upper surface portion 27 in the vehicle width direction. In a state where the first and second members 21 and 22 are assembled to the vehicle body P, a pair of screws S are inserted into the screw insertion holes 23b and 25a of the first and second members 21 and 22, respectively. Bolts B are screwed so that the vehicle body P (panel) is sandwiched between the screws S. As a result, the first and second members 21 and 22 are screwed and fixed to the vehicle body P.

  The connecting cylinder part 26 is inserted through the insertion hole 23 a of the base part 23. One end (see FIG. 1) of a hose 7c branched and connected by a T-joint or the like in the middle of the hose 7b toward the rear nozzle 6 is inserted into the connecting cylinder portion 26 so that the cleaning liquid W is introduced. ing. The nozzle upper surface portion 27 has a shape corresponding to the nozzle lower surface portion 24 and is combined with the nozzle lower surface portion 24 to constitute the nozzle portion 31 (see FIG. 2). The nozzle part 31 communicates with the connection cylinder part 26, and the cleaning liquid W introduced from the connection cylinder part 26 flows into the nozzle part 31. The nozzle upper surface portion 27 is in contact with the upper end surface of the rectifying portion 24c of the nozzle lower surface portion 24, and the cleaning liquid W flowing through the nozzle portion 31 is between the rectifying portions 24c and between the rectifying portions 24c and the side surface portions 24b. It has come to flow mainly.

  As shown in FIG. 2, the nozzle portion 31 is slightly bent downward and extends downward in the vertical direction so as not to protrude rearward of the vehicle body (imaging direction side) from the camera 10. It is configured. The front end (lower end) of the nozzle portion 31 is a discharge port 31a through which the cleaning liquid W is discharged, and the discharge port 31a is located above the downward slope surface 14 of the camera 10. That is, the discharge port 31 a of the nozzle portion 31 is configured to face the downward slope surface 14 of the camera 10. Moreover, the nozzle part 31 has comprised the shape extended in the vehicle width direction from the fundamental part near the vehicle body P to the discharge outlet 31a. As a result, the discharge port 31 a is formed so that the dimension in the vehicle width direction (direction perpendicular to the discharge direction) is larger than that of the connecting tube portion 26. The rectifying unit 24c is formed from the middle part of the nozzle part 31 in the ejection direction to the ejection port 31a. The nozzle portion 31 serves as a guide portion that guides the cleaning liquid W introduced from the connection tube portion 26 toward the descending slope surface 14.

  A part of the camera 10 and the camera nozzle 20 are covered with a garnish G provided at the rear part of the vehicle body P. The garnish G covers the vehicle body rear side of the camera nozzle 20. That is, the camera nozzle 20 is disposed in a space between the garnish G provided at the rear portion of the vehicle body P and the vehicle body P. Further, the camera 10 is configured such that the base portion including the base portion 11 is covered with the garnish G, and the tip portion including the imaging surface 13 protrudes from the opening Ga of the garnish G. A gap having a predetermined interval is formed between the descending slope surface 14 of the camera 10 and the opening Ga of the garnish G. Thus, since the camera nozzle 20 is covered with the garnish G, the camera nozzle 20 is difficult to see.

Next, the operation of the above embodiment will be described.
When the cleaning liquid W is supplied to the camera nozzle 20 together with the rear nozzle 6 by the operation of the pump device 4, the cleaning liquid W is discharged from the discharge port 31 a of the nozzle portion 31, and the cleaning liquid W reaches the downward slope surface 14 of the camera 10. Water. The cleaning liquid W that has landed on the downward slope surface 14 flows to the imaging surface 13 on the front surface of the housing 12 following the inclination of the downward slope surface 14. That is, the cleaning liquid W discharged from the discharge port 31a of the camera nozzle 20 is indirectly supplied to the imaging surface 13 via the descending slope surface 14, and foreign substances such as raindrops and mud on the imaging surface 13 are caused by the cleaning liquid W. It is designed to be washed away.

  Here, since the cleaning liquid W passing through the nozzle portion 31 is discharged from the discharge port 31a in a state of expanding in the vehicle width direction following the wide shape of the nozzle portion 31, the cleaning liquid W over the entire imaging surface 13. Is supplied. Further, since the rectifying unit 24c extending along the discharge direction is provided in the nozzle unit 31, the cleaning liquid W is rectified by the rectifying unit 24c before being discharged from the discharge port 31a. In this case, the cleaning liquid W is prevented from scattering in an unintended direction.

Next, characteristic effects of the present embodiment will be described.
(1) The in-vehicle camera 10 has a downwardly inclined surface 14 that is inclined downward in the vertical direction toward the imaging surface 13 side on the upper side of the imaging surface 13 in the attached state to the vehicle body P, and is discharged from the camera nozzle 20. The outlet 31 a is configured to discharge the cleaning liquid W toward the downward slope surface 14. As a result, the cleaning liquid W discharged from the discharge port 31a of the camera nozzle 20 lands on the downward slope surface 14 of the in-vehicle camera 10, and flows from there to the imaging surface 13 following the inclination of the downward slope surface 14, and the cleaning liquid The dirt on the imaging surface 13 can be removed by W. As described above, the cleaning liquid W is discharged from the discharge port 31 a of the camera nozzle 20 toward the downward gradient surface 14, and the cleaning liquid W is indirectly supplied to the imaging surface 13 through the downward gradient surface 14. Thus, unlike the conventional configuration, it is not necessary to set the discharge port 31a of the camera nozzle 20 in the vicinity of the imaging surface 13 in order to supply the cleaning liquid W directly to the imaging surface 13. Thereby, for example, regardless of the configuration such as the size of the in-vehicle camera 10, the camera nozzle 20 can be separated upward from the in-vehicle camera 10 to be independent from the camera. For this reason, it is possible to deal with various types of in-vehicle cameras 10 with the camera nozzle 20 having the same configuration, and as a result, versatility can be improved.

  Further, since the cleaning liquid W is indirectly supplied from the camera nozzle 20 to the imaging surface 13 via the descending slope surface 14, the camera nozzle 20 is configured not to protrude from the imaging surface 13 toward the imaging direction. As a result, the appearance design of the in-vehicle camera 10 and the camera nozzle 20 can be improved.

  (2) The camera nozzle 20 is disposed away from the in-vehicle camera 10. Thereby, since the nozzle 20 for cameras and the vehicle-mounted camera 10 do not receive restrictions of a structure, such as a shape, those design freedom can be improved. Further, even when the camera nozzle 20 and the in-vehicle camera 10 vibrate due to the influence from the vehicle body P side, they are unlikely to interfere with each other, and as a result, the risk of damage to the camera nozzle 20 and the in-vehicle camera 10 can be reduced.

(3) Since the camera nozzle 20 is fixed only to the vehicle body P, the camera nozzle 20 can be easily fixed.
(4) Since the ejection port 31a is formed wider than the connection port in the direction orthogonal to the ejection direction, the cleaning liquid W can be suitably supplied over the entire imaging surface 13.

  (5) The discharge port 31a is provided with a rectifying unit 24c that rectifies the discharged cleaning liquid W. Accordingly, since the cleaning liquid W discharged from the discharge port 31a is rectified by the rectifying unit 24c, it is possible to suppress scattering in an unintended direction when the cleaning liquid W is discharged.

  (6) The camera nozzle 20 is provided at the rear part of the vehicle body P together with the in-vehicle camera 10, and is disposed in a space between the garnish G provided at the rear part of the vehicle body P and the vehicle body P. Accordingly, the rear side of the vehicle body of the camera nozzle 20 is covered with the garnish G, so that the camera nozzle 20 that tends to be functional and poor in design can be avoided from being viewed, and the rear part of the vehicle body P The imaging surface 13 can be cleaned without impairing the design. Further, in such a configuration, since the camera nozzle 20 is configured not to protrude from the imaging surface 13 toward the photographing direction, it is possible to suppress the camera nozzle 20 from interfering with the garnish G. It becomes possible.

In addition, you may change embodiment of this invention as follows.
-You may change the structure of the nozzle 20 for cameras of the said embodiment as shown, for example in FIG.4 and FIG.5. In the configuration shown in FIGS. 4 and 5, the camera nozzle 40 includes a nozzle body 41 having an ejection port 41 a that ejects the cleaning liquid W, and a guide member 42 that is configured separately from the nozzle body 41 and has an ejection port 42 a. It is composed of

  The guide member 42 has a fixing portion 43 fixed to the nozzle fixing portion Pb of the vehicle body P by a pair of screws S (see FIG. 5), and holds the nozzle body 41 at a portion between the screws S of the fixing portion 43. doing.

  The nozzle body 41 has a connection cylinder portion 26 similar to that in the above-described embodiment, and the connection cylinder portion 26 is inserted and held in the fixing portion 43 of the guide member 42. A head portion 44 that protrudes from the guide member 42 is formed at the distal end portion of the nozzle body 41, and a jet outlet 41 a that communicates with the connecting tube portion 26 is formed in the head portion 44. The cleaning liquid W introduced from the connection cylinder part 26 flows at a substantially right angle at the head part 44 and is ejected downward along the nozzle fixing part Pb from the ejection port 41a.

  The guide member 42 is formed with a guide portion 45 extending from the fixed portion 43. The guide portion 45 is formed in a substantially U-shaped cross section from the bottom surface portion 45a and the side surface portion 45b extending substantially perpendicularly upward from both edges in the vehicle width direction of the bottom surface portion 45a, and at the root portion. On the other hand, the discharge port 42a at the tip has a shape that expands in the vehicle width direction (see FIG. 5). The bottom surface portion 45a of the guide portion 45 is inclined downward in the vertical direction toward the vehicle body rear side. The guide member 42 guides the cleaning liquid W ejected from the ejection port 41 a toward the bottom surface portion 45 a by the guide portion 45, ejects the cleaning liquid W from the ejection port 42 a toward the downward gradient surface 14, and landed on the downward gradient surface 14. The cleaning liquid W flows to the imaging surface 13 following the inclination of the descending slope surface 14.

  With such a configuration, it is possible to obtain substantially the same operations and effects as in the above embodiment. Furthermore, since the camera nozzle 40 is composed of a nozzle body 41 and a guide member 42 that are configured separately, the nozzle body 41 has the same configuration and changes only the guide member 42 in order to greatly change the specifications of the in-vehicle camera 10. Can respond.

  In addition, since the guide member 42 is configured separately from the nozzle body 41, the guide member 42 can be made of a material different from that of the nozzle body 41. For this reason, for example, when the guide member 42 is made of an elastic material such as rubber, the guide member 42 and the descending slope surface 14 of the camera 10 collide with each other due to vibration from the vehicle body P side or the like. The positional deviation and damage of the camera 10 can be suppressed.

The configuration of the camera nozzle 20 of the above embodiment may be a configuration in which the nozzle body 41 and the guide member 42 shown in FIGS. 4 and 5 are formed as an integral part.
In the above embodiment, the first member 21 and the second member 22 of the camera nozzle 20 are configured separately, but the present invention is not particularly limited thereto, and the first member 21 and the second member 22 are not limited thereto. May be formed as an integral part.

-The imaging surface 13 of the said embodiment may be comprised with the lens, and does not need to be comprised with the lens.
In the above embodiment, the cleaning liquid W discharged from the discharge port 31a of the camera nozzle 20 and landing on the descending slope surface 14 is caused by the step portion 12a (see FIGS. 2 and 3) provided on the outer surface of the housing 12. You may guide to the imaging surface 13. FIG. According to this configuration, the cleaning liquid W discharged from the discharge port 31a can be efficiently supplied to the imaging surface 13.

  In the above embodiment, the camera 10 is tilted downward so that the imaging surface 13 on the front surface captures the lower rear part, so that the upper surface of the camera 10 moves vertically toward the front surface (imaging surface 13) side. Although it is the downward slope surface 14 which inclines below, it is not specifically limited to this.

  For example, as shown in FIG. 6, the vehicle-mounted camera may be configured as a trapezoidal camera 50 that tapers toward the imaging surface 50a on the front surface, and the inclined upper surface may be configured as a downward gradient surface 50b. In addition, as shown in FIG. 7, the in-vehicle camera may be a hemispherical camera 60, and the upper curved portion of the front imaging surface 50a may be configured as a descending slope surface 60b. According to the configuration shown in FIGS. 6 and 7, even when the imaging direction of the cameras 50 and 60 (installation direction of the camera 10) is horizontal or nearly horizontal, the downgraded surfaces 50b and 60b are imaged. It can comprise so that it may incline in the perpendicular direction downward as it goes to the surface 50a, 60a side, As a result, it can contribute to the improvement of a design freedom.

  In the above embodiment, the camera nozzle 20 is supported only by the vehicle body P. However, for example, a configuration may be employed in which the camera nozzle 20 is supported by the vehicle body P and the inner part of the garnish G.

  In the nozzle 20 for the camera of the above embodiment and the nozzle body 41 having the configuration shown in FIGS. 4 and 5, a check for preventing the leakage of the cleaning liquid W from the discharge port 31a or the jet port 41a when the pump device 4 is stopped. A valve may be provided.

  In the above embodiment, the hose 7c is simply branched from the hose 7b directed toward the rear nozzle 6 and connected to the camera nozzle 20, and the cleaning liquid W is ejected from the camera nozzle 20 simultaneously with the ejection of the cleaning liquid W from the rear nozzle 6. Although implemented, it is not particularly limited to this. For example, the pump device 4 may be individually provided for the rear nozzle 6 and the camera nozzle 20 or may be operated independently using a switching valve for switching the flow path between the rear nozzle 6 and the camera nozzle 20. Good.

  In the above embodiment, the present invention is applied to the camera nozzle 20 that cleans the camera 10 for rearward viewing, but the camera that cleans other in-vehicle cameras such as a side view camera for lateral viewing and a front view camera for frontward viewing. It may be applied to a nozzle for use.
