[0001] The present invention relates to a cleaning device mounted on a support body having an opening or a concave surface. Background Art

[0002] Patent document 1 discloses a cleaning device mounted on a support body, the support body being provided as a part of a vehicle as an example of a mobile body. The cleaning device has a nozzle for spraying a cleaning liquid as an example of a fluid for washing a headlight. When the cleaning liquid is not sprayed, the nozzle is covered by a part of the support body. When the cleaning liquid is sprayed, a part of the support body is displaced and the nozzle is exposed.

[0003] Patent Document 1: Japanese Patent Application Publication No. 2019-156210 Summary of the invention

[0004] It is required to reduce the visibility of the cleaning device as described above.

[0005] A first embodiment provided by the present invention is a cleaning device mounted on a support having an opening, the cleaning device comprising:

[0006] a nozzle that ejects a fluid toward an object;

[0007] a bracket that holds the nozzle in a fixed position; and

[0008] a bonding portion, which bonds the bracket to the inner surface of the support body,

[0009] The bracket has:

[0010] a guide portion having a concave surface for guiding the fluid toward the object; and

[0011] a cover covering at least a portion of the nozzle when viewed from a side corresponding to an outer surface of the support body,

[0012] The outer edge of the guide portion and the outer edge of the cover are configured so that, when the cleaning device is attached to the support body, the outer edge of the guide portion and the outer edge of the cover are located inside the inner edge of the opening.

[0013] According to the structure involved in the first embodiment, the outer edge of the guide portion of the bracket and the outer edge of the cover are located at the inner side of the inner edge of the opening, so that the bracket and the inner surface can be bonded by the bonding portion through the simple action of passing the guide portion and the cover through the opening from the side corresponding to the inner surface of the support body, and the cleaning device can be mounted on the support body. It is unnecessary to perform the operation from the side corresponding to the outer surface of the support body, so that the production equipment can be simplified and the productivity can be improved.

[0014] On this basis, the size of the portion of the bracket exposed through the opening to the side corresponding to the outer surface of the support body can be reduced. Combined with the appearance that at least a portion of the nozzle is covered by the cover when viewed from the side corresponding to the outer surface, the visual recognition of the cleaning device can be reduced.

[0015] A second embodiment provided by the present invention is a cleaning device mounted on a support having an opening, the cleaning device comprising:

[0016] a nozzle that ejects a fluid toward an object;

[0017] a bracket that holds the nozzle in a fixed position; and

[0018] a bonding portion, which bonds the bracket to the inner surface of the support body,

[0019] The bracket has a guide portion having a concave surface for guiding the fluid toward the object.

[0020] The nozzle is arranged so that, if the cleaning device is mounted on the support body, at least a portion of the nozzle is covered by the support body when viewed from a side corresponding to an outer surface of the support body,

[0021] The outer edge of the guide portion is configured so that, when the cleaning device is attached to the support body, the outer edge of the guide portion is located inside of the inner edge of the opening.

[0022] According to the structure involved in the second embodiment, the outer edge of the guide portion of the bracket is located at a position closer to the inside than the inner edge of the opening portion, so that the bracket and the inner surface can be bonded by the bonding portion through the simple action of passing the guide portion through the opening portion from the side corresponding to the inner surface of the support body, and the cleaning device can be mounted on the support body. It is unnecessary to perform operations from the side corresponding to the outer surface of the support body, so that the production equipment can be simplified and the productivity can be improved.

[0023] On this basis, when viewed from the side corresponding to the outer surface of the support body, at least a portion of the nozzle is covered by the support body itself, so that the size of the portion of the bracket exposed to the side corresponding to the outer surface through the opening can be reduced. Therefore, the visual recognition of the cleaning device can be reduced.

[0024] A third embodiment provided by the present invention is a cleaning device mounted on a support having a concave surface, the cleaning device comprising:

[0025] a nozzle that ejects a fluid toward an object;

[0026] a bracket that holds the nozzle in a fixed position; and

[0027] a bonding portion, which bonds the bracket to the inner surface of the support body,

[0028] The bracket has an opening portion, and the opening portion receives the concave surface on a side corresponding to the inner surface of the support body.

[0029] The nozzle is configured so that, if the cleaning device is mounted on the support body, the fluid is guided toward the object through the concave surface.

[0030] The nozzle is arranged so that, when the cleaning device is mounted on the support body, at least a portion of the nozzle is covered by the support body when viewed from a side corresponding to an outer surface of the support body.

[0031] According to the structure involved in the third embodiment, the bracket has an opening portion for receiving the concave surface of the support body on the side corresponding to the inner surface of the support body, so that the cleaning device can be attached to the support body by bonding the bracket and the inner surface by the bonding portion through a simple action of accommodating the concave surface from the side corresponding to the inner surface of the support body. It is unnecessary to perform the operation from the side corresponding to the outer surface of the support body, so that the production equipment can be simplified and the productivity can be improved.

[0032] On this basis, it is possible to make it difficult to visually identify the bracket from the side corresponding to the outer surface of the support body. Combined with the appearance that at least a portion of the nozzle is covered by the support body itself when viewed from the side corresponding to the outer surface of the support body, the visual recognition of the cleaning device can be reduced.

[0033] A fourth embodiment provided by the present invention is a cleaning device mounted on a support having a concave surface, the cleaning device comprising:

[0034] a nozzle that ejects a fluid toward an object; and

[0035] a snap-fitting portion that snaps into the support body at a side corresponding to the inner surface of the support body, thereby holding the nozzle in a fixed position,

[0036] The nozzle is configured so that, if the cleaning device is mounted on the support body, the fluid is guided toward the object through the concave surface.

[0037] The nozzle is arranged so that, when the cleaning device is mounted on the support body, at least a portion of the nozzle is covered by the support body when viewed from a side corresponding to an outer surface of the support body.

[0038] According to the structure involved in the fourth embodiment, the cleaning device can be mounted on the support body by a simple action of engaging the nozzle with the support body through the engaging portion from the side corresponding to the inner surface of the support body. It is unnecessary to perform operations from the side corresponding to the outer surface of the support body, thereby simplifying the production equipment and improving the productivity.

[0039] On this basis, it is possible to make it difficult to visually recognize the nozzle from the side corresponding to the outer surface of the support body, so that the visibility of the cleaning device can be reduced.

[0040] A fifth embodiment provided by the present invention is a cleaning device mounted on a support having an opening, the cleaning device comprising:

[0041] a nozzle that ejects a fluid toward an object;

[0042] a bracket that holds the nozzle of the support body in a fixed position; and

[0043] a bonding portion, which bonds the bracket to the inner surface of the support body,

[0044] The nozzle is configured so that, when the cleaning device is mounted on the support body, the fluid passing through the opening is sprayed onto the object.

[0045] The nozzle is arranged so that, when the cleaning device is mounted on the support body, at least a portion of the nozzle is covered by the support body when viewed from a side corresponding to an outer surface of the support body.

[0046] According to the structure involved in the fifth embodiment, the cleaning device can be mounted on the support body by a simple action of pressing the bracket to the support body from the side corresponding to the inner surface of the support body, so that the bracket and the inner surface are bonded by the bonding portion. It is unnecessary to perform work from the side corresponding to the outer surface of the support body, thereby simplifying the production equipment and improving the productivity.

[0047] Furthermore, since the nozzle and the object can be directly opposed to each other through the opening of the support body, the degree of freedom regarding the positional relationship between the two can be increased.

[0048] On this basis, it is possible to make it difficult to visually identify the bracket from the side corresponding to the outer surface of the support body. Combined with the appearance that at least a portion of the nozzle is covered by the support body itself when viewed from the side corresponding to the outer surface of the support body, the visual recognition of the cleaning device can be reduced.

[0070] Hereinafter, an example of the embodiment will be described in detail with reference to the drawings. In the drawings used in the following description, the scale is changed as necessary to make each component a recognizable size.

[0071] In the drawings, arrow F indicates the front direction of the illustrated structure. Arrow B indicates the rear direction of the illustrated structure. Arrow U indicates the upper direction of the illustrated structure. Arrow D indicates the lower direction of the illustrated structure. Arrow R indicates the right direction of the illustrated structure. Arrow L indicates the left direction of the illustrated structure. The expressions involved in these directions are intended to facilitate explanation and are not intended to limit the posture of the structure when it is actually used.

[0072] Figure 1 The appearance of the cleaning device 10 according to the first embodiment is shown as an example. Figure 2 As shown in the example in FIG. 1 , the cleaning device 10 is a device installed on a support body 61 to clean the lighting device 70. For example, the lighting device 70 may be mounted on a Figure 3 The support body 61 may be a member constituting a part of the vehicle 80. The vehicle 80 is an example of a moving body.

[0073] like Figure 2 As shown in the example, the lighting device 70 has a translucent cover 71. The translucent cover 71 divides the lamp chamber that accommodates the light source 72, and allows the light emitted from the light source 72 to pass through. The cleaning device 10 has a nozzle 11. The cleaning device 10 is configured to spray a cleaning liquid W from the nozzle 11 toward the translucent cover 71, thereby performing cleaning. The translucent cover 71 is an example of an object. The cleaning liquid W is an example of a fluid.

[0074] Figure 4 Example of edge Figure 2 The cleaning device 10 is a cross section viewed from the arrow direction along the line IV-IV. The cleaning device 10 includes a joint 12. The joint 12 is configured to be connected to one end of a supply pipe (not shown) for the cleaning liquid W. The joint 12 includes a flow path 121 communicating with the supply pipe.

[0075] On the other hand, the nozzle 11 has an injection port 111 and a flow path 112. The flow path 112 is connected to the injection port 111. When the nozzle 11 is connected to the joint 12, the flow path 112 is connected to the flow path 121. Thus, a flow path for the cleaning liquid W to reach the injection port 111 from the supply pipe is formed. The cleaning liquid W is ejected from the injection port 111.

[0076] The cleaning device 10 has a bracket 13. The bracket 13 is configured to hold the nozzle 11 at a fixed position. In other words, the position of the nozzle 11 in the cleaning device 10 does not change, and is different from a cleaning device having a so-called pop-up nozzle.

[0077] like Figure 1 As shown in the example in FIG. 1 , the cleaning device 10 has an adhesive portion 14. Figure 4 As shown in the example in FIG. 8 , the bonding portion 14 bonds the bracket 13 to the inner surface 611 of the support body 61. That is, the cleaning device 10 is attached to the support body 61 from the inner surface 611 side.

[0078] In this example, the adhesive portion 14 is implemented by a strip material having adhesive layers on both sides. One adhesive layer of the strip material is bonded to the supported surface 131 of the bracket 13 , and the other adhesive layer is bonded to the inner surface 611 of the support body 61 .

[0079] In addition, the bonding portion 14 may be realized by an adhesive applied when the cleaning device 10 is attached to the support 61 .

[0080] like Figure 1 As shown in the example in FIG. 1 , the bracket 13 has a guide portion 132 and a cover 133. Figure 2 and Figure 4 As shown in the example in FIG. 6 , an opening 612 is formed in the support body 61 . When the cleaning device 10 is mounted on the support body 61 , the guide portion 132 and the cover 133 are exposed through the opening 612 to a side corresponding to an outer surface 613 of the support body 61 .

[0081] like Figure 1 and Figure 2 As shown in the example in FIG. 1 , the guide portion 132 has a concave surface 132 a . The concave surface 132 a has a size and a shape capable of guiding the cleaning liquid W ejected from the nozzle 11 toward the light-transmitting cover 71 .

[0082] The cover 133 is formed to cover at least a portion of the nozzle 11 when viewed from a side corresponding to the outer surface 613 of the support body 61 .

[0083] like Figure 2 and Figure 4 As shown in the example in FIG. 6 , the outer edge 132 b of the guide portion 132 and the outer edge 133 a of the cover 133 are located inside the inner edge 612 a of the opening 612 .

[0084] Figure 5 The bracket of the cleaning device according to the comparative example is shown. The bracket has a cover 133'. Although not shown in the figure, the cover 133' is arranged to cover the nozzle located below.

[0085] The cover 133' has a snap-fitting portion 134'. The snap-fitting portion 134' is snap-fitted in a manner of sandwiching the inner edge 612a of the opening 612 of the support 61 from the thickness direction of the support 61, thereby fixing the bracket to the support 61. According to its structure, the outer edge 133a' of the cover 133' has to be located outside the inner edge 612a of the opening 612. The size of the portion exposed to the side corresponding to the outer surface 613 of the support 61 is increased accordingly, so that the visual recognition of the cleaning device is improved.

[0086] On this basis, the cover 133' needs to be inserted into the opening 612 from the side corresponding to the outer surface 613 according to its structure. Therefore, in order to combine the bracket 13' with the nozzle, it is necessary to work from both the side corresponding to the inner surface 611 of the support body 61 and the side corresponding to the outer surface 613.

[0087] On the other hand, in the structure according to the present embodiment, the outer edge 132b of the guide portion 132 of the bracket 13 and the outer edge 133a of the cover 133 are located inside the inner edge 612a of the opening 612, so that the cleaning device 10 can be attached to the support 61 by bonding the bracket 13 and the inner surface 611 by the bonding portion 14 through a simple operation of passing the guide portion 132 and the cover 133 through the opening 612 from the side corresponding to the inner surface 611 of the support 61. Since the operation from the side corresponding to the outer surface 613 of the support 61 is not required, the production equipment can be simplified and the productivity can be improved.

[0088] On this basis, the size of the portion of the bracket 13 exposed to the side corresponding to the outer surface 613 of the support body 61 through the opening 612 can be reduced. Combined with the appearance that at least a portion of the nozzle 11 is covered by the cover 133 when viewed from the side corresponding to the outer surface 613, the visual recognition of the cleaning device 10 can be reduced.

[0089] Figure 6The appearance of the cleaning device 20 according to the second embodiment is shown as an example. Figure 7 As shown in the example in FIG. 2 , the cleaning device 20 is mounted on the support 62 to clean the lighting device 70. The support 62 may be a Figure 3 Components of a portion of vehicle 80 are illustrated in FIG.

[0090] like Figure 7 As shown in the example in FIG. 2 , the cleaning device 20 includes a nozzle 21. The cleaning device 20 is configured to spray the cleaning liquid W from the nozzle 21 toward the light-transmitting cover 71 to perform cleaning.

[0091] Figure 8 Example of edge Figure 7 The cleaning device 20 is a cross section viewed from the arrow direction along the line VIII-VIII. The cleaning device 20 includes a joint 22. The joint 22 is configured to be connected to one end of a supply pipe (not shown) of the cleaning liquid W. The joint 22 includes a flow path 221 communicating with the supply pipe.

[0092] On the other hand, the nozzle 21 has an injection port 211 and a flow path 212. The flow path 212 is connected to the injection port 211. When the nozzle 21 is connected to the joint 22, the flow path 212 is connected to the flow path 221. Thus, a flow path for the cleaning liquid W to reach the injection port 211 from the supply pipe is formed. The cleaning liquid W is ejected from the injection port 211.

[0093] The cleaning device 20 has a bracket 23. The bracket 23 is configured to hold the nozzle 21 at a fixed position. In other words, the position of the nozzle 21 in the cleaning device 20 does not change, and is different from a cleaning device having a so-called pop-up nozzle.

[0094] like Figure 6 As shown in the example in FIG. 2 , the cleaning device 20 has an adhesive portion 24. Figure 8 As shown in the example in FIG. 8 , the bonding portion 24 bonds the bracket 23 to the inner surface 621 of the support body 62. That is, the cleaning device 20 is attached to the support body 62 from one side of the inner surface 621.

[0095] In this example, the adhesive portion 24 is implemented by a strip material having adhesive layers on both sides. One adhesive layer of the strip material is bonded to the supported surface 231 of the bracket 23 , and the other adhesive layer is bonded to the inner surface 621 of the support body 62 .

[0096] In addition, the bonding portion 24 may be realized by an adhesive applied when the cleaning device 20 is attached to the support body 62 .

[0097] like Figure 6 As shown in the example in FIG. 2 , the bracket 23 has a guide portion 232 . The guide portion 232 has a concave surface 232 a . The concave surface 232 a has a size and a shape capable of guiding the cleaning liquid W ejected from the nozzle 21 toward the light-transmitting cover 71 .

[0098] On the other hand, Figure 7 and Figure 8 As shown in the example in FIG. 6 , an opening 622 is formed in the support body 62 . When the cleaning device 20 is mounted on the support body 62 , the guide portion 232 is exposed to a side corresponding to an outer surface 623 of the support body 62 through the opening 622 .

[0099] At this time, the outer edge 232b of the guide portion 232 is located inside the inner edge 622a of the opening 622. The nozzle 21 is arranged so that at least a part thereof is covered by the support 62 when viewed from the side corresponding to the outer surface 623 of the support 62.

[0100] In the structure involved in this embodiment, the outer edge 232b of the guide portion 232 of the bracket 23 is located at a position closer to the inside than the inner edge 622a of the opening portion 622. Therefore, by a simple action of passing the guide portion 232 through the opening portion 622 from the side corresponding to the inner surface 621 of the support body 62, the bracket 23 and the inner surface 621 can be bonded by the bonding portion 24, and the cleaning device 20 can be mounted on the support body 62. The operation from the side corresponding to the outer surface 623 of the support body 62 can be eliminated, so that the production equipment can be simplified and the productivity can be improved.

[0101] On this basis, when viewed from the side corresponding to the outer surface 623 of the support body 62, at least a portion of the nozzle 21 is covered by the support body 62 itself, so that the size of the portion of the bracket 23 exposed to the side corresponding to the outer surface 623 through the opening 622 can be reduced. Therefore, the visual recognition of the cleaning device 20 can be reduced.

[0102] like Figure 6 and Figure 7 As shown in the example in FIG. 2 , the guide portion 232 includes a deflecting portion 232 c . The deflecting portion 232 c is formed as a wall that can deflect the traveling direction of the cleaning liquid W ejected from the nozzle 21 toward the light-transmitting cover 71 .

[0103] Figure 7 The arrows indicated by the two-dot chain line in the figure indicate the path of the cleaning liquid W that is assumed to flow when the deflection unit 232c is not present. It is found that the cleaning liquid W that is not deflected by the deflection unit 232c does not contribute to the cleaning of the light-transmitting cover 71 and is consumed. By providing the deflection unit 232c as shown in this example, the utilization efficiency of the cleaning liquid W can be improved.

[0104] The same deflecting portion may be formed in the guide portion 132 of the bracket 13 of the cleaning device 10 according to the first embodiment.

[0105] Fig. 9The appearance of the cleaning device 30 according to the third embodiment is shown as an example. Fig.10 As shown in the example in FIG. 1 , the cleaning device 30 is a device installed on a support body 63 to clean the lighting device 70. The support body 63 may be a Figure 3 Components of a portion of vehicle 80 are illustrated in FIG.

[0106] like Fig.10 As shown in the example in FIG. 3 , the cleaning device 30 includes a nozzle 31. The cleaning device 30 is configured to spray the cleaning liquid W from the nozzle 31 toward the light-transmitting cover 71 to perform cleaning.

[0107] Fig.11 Example of edge Fig.10 The cleaning device 30 is a cross section viewed from the arrow direction along the line XI-XI. The cleaning device 30 includes a joint 32. The joint 32 is configured to be connected to one end of a supply pipe (not shown) of the cleaning liquid W. The joint 32 includes a flow path 321 communicating with the supply pipe.

[0108] On the other hand, the nozzle 31 has an injection port 311 and a flow path 312. The flow path 312 is connected to the injection port 311. When the nozzle 31 is connected to the joint 32, the flow path 312 is connected to the flow path 321. Thus, a flow path for the cleaning liquid W to reach the injection port 311 from the supply pipe is formed. The cleaning liquid W is ejected from the injection port 311.

[0109] The cleaning device 30 has a bracket 33. The bracket 33 is configured to hold the nozzle 31 at a fixed position. In other words, the position of the nozzle 31 in the cleaning device 30 does not change, and is different from a cleaning device having a so-called pop-up nozzle.

[0110] like Fig. 9 As shown in the example in FIG. 3 , the cleaning device 30 has an adhesive portion 34. Fig.11 As shown in the example in FIG. 8 , the bonding portion 34 bonds the bracket 33 to the inner surface 631 of the support body 63. That is, the cleaning device 30 is attached to the support body 63 from one side of the inner surface 631.

[0111] In this example, the adhesive portion 34 is implemented by a strip material having adhesive layers on both sides. One adhesive layer of the strip material is bonded to the supported surface 331 of the bracket 33 , and the other adhesive layer is bonded to the inner surface 631 of the support body 63 .

[0112] In addition, the bonding portion 34 may be realized by an adhesive applied when the cleaning device 30 is attached to the support body 63 .

[0113] like Fig.10 and Fig.11As shown in the example in FIG. 6 , the support body 63 has a concave surface 634 . The concave surface 634 is formed as a surface that is connected to the outer surface 633 of the support body 63 and is recessed toward a side corresponding to the inner surface 631 relative to the outer surface 633 .

[0114] On the other hand, Fig. 9 As shown in the example in FIG. 3 , the bracket 33 of the cleaning device 30 has an opening 332. Fig.11 As shown in the example in FIG. 8 , the opening 332 has a shape and a size that can accommodate the concave surface 634 when the cleaning device 30 is attached to the support body 63 .

[0115] At this time, the nozzle 31 is arranged so that at least a portion thereof is covered by the support 63 when viewed from the side corresponding to the outer surface 633 of the support 63. The nozzle 31 is arranged so that the ejected cleaning liquid W can be guided toward the light-transmitting cover 71 of the lighting device 70 through the concave surface 634 of the support 63.

[0116] In the structure involved in this embodiment, the bracket 33 has the opening portion 332 for receiving the concave surface 634 of the support body 63 on the side corresponding to the inner surface 631 of the support body 63. Therefore, by a simple action of causing the opening portion 332 to receive the concave surface 634 from the side corresponding to the inner surface 631 of the support body 63, the bracket 33 and the inner surface 631 can be bonded by the bonding portion 34, and the cleaning device 30 can be attached to the support body 63. The operation from the side corresponding to the outer surface 633 of the support body 63 can be eliminated, so that the production equipment can be simplified and the productivity can be improved.

[0117] On this basis, it is possible to make it difficult to visually identify the bracket 43 from the side corresponding to the outer surface 633 of the support body 63. In combination with the appearance that at least a portion of the nozzle 31 is covered by the support body 63 itself when viewed from the side corresponding to the outer surface 633 of the support body 63, the visual recognition of the cleaning device 30 is reduced.

[0118] The arrangement of the nozzle 31 is determined so that the ejected cleaning liquid W is deflected toward the light-transmitting cover 71 by a portion of the concave surface 634 . Fig.10 The arrow indicated by the double-dashed line in the middle indicates the path of the cleaning liquid W assumed to flow when not deflected by the concave surface 634. It is found that the cleaning liquid W not deflected by the concave surface 634 does not contribute to the cleaning of the light-transmitting cover 71 and is consumed. By determining the configuration of the nozzle 31 as described above, the utilization efficiency of the cleaning liquid W can be improved.

[0119] Fig.12 The appearance of the cleaning device 40 according to the fourth embodiment is shown as an example. Fig.13As shown in the example in FIG. 4 , the cleaning device 40 is mounted on a support 64 and cleans the lighting device 70. The support 64 may be a Figure 3 Components of a portion of vehicle 80 are illustrated in FIG.

[0120] like Fig.13 As shown in the example in FIG. 4 , the cleaning device 40 includes a nozzle 41. The cleaning device 40 is configured to spray the cleaning liquid W from the nozzle 41 toward the light-transmitting cover 71 to perform cleaning.

[0121] Fig.14 Example of edge Fig.13 The cleaning device 40 is a cross section viewed from the arrow direction along the line XIV-XIV. The cleaning device 40 includes a joint 42. The joint 42 is configured to be connected to one end of a supply pipe (not shown) of the cleaning liquid W. The joint 42 includes a flow path 421 communicating with the supply pipe.

[0122] On the other hand, the nozzle 41 has an injection port 411 and a flow path 412. The flow path 412 is connected to the injection port 411. When the nozzle 41 is connected to the joint 42, the flow path 412 is connected to the flow path 421. Thus, a flow path for the cleaning liquid W to reach the injection port 411 from the supply pipe is formed. The cleaning liquid W is ejected from the injection port 411.

[0123] like Fig.12 and Fig.14 As shown in the example in FIG. 6 , the support body 64 has a bracket portion 640. The bracket portion 640 extends from an inner surface 641 of the support body 64 and has a hollow cylindrical shape.

[0124] On the other hand, the cleaning device 40 has an engagement portion 44. The engagement portion 44 is configured to engage with the bracket portion 640, thereby holding the nozzle 41 at a fixed position in the bracket portion 640. The engagement portion 44 can be realized by a known snap-fit ​​structure or the like.

[0125] That is, the cleaning device 40 is attached to the support body 64 from one side of the inner surface 641. The position of the nozzle 41 in the cleaning device 40 is unchanged, and it is different from the cleaning device having a so-called pop-up nozzle.

[0126] like Fig.13 and Fig.14 As shown in the example, the support body 64 has a concave surface 644. The concave surface 644 is formed as a surface that is connected to the outer surface 643 of the support body 64 and is recessed toward the side corresponding to the inner surface 641 compared to the outer surface 643. On the other hand, the concave surface 644 is connected to the inner peripheral surface of the bracket part 640.

[0127] If the cleaning device 40 is mounted on the support body 64, the nozzle 41 is configured so that at least a portion thereof is covered by the support body 64 when viewed from the side corresponding to the outer surface 643 of the support body 64. The configuration of the nozzle 41 is determined so that the sprayed cleaning liquid W is guided toward the light-transmitting cover 71 of the lighting device 70 through the concave surface 644 of the support body 64.

[0128] In the structure involved in this embodiment, the cleaning device 40 can be mounted on the support body 64 by a simple action of engaging the nozzle 41 with the support body 64 through the engaging portion 44 from the side corresponding to the inner surface 641 of the support body 64. The operation from the side corresponding to the outer surface 643 of the support body 64 is unnecessary, so that the production equipment can be simplified and the productivity can be improved.

[0129] On this basis, it is possible to make it difficult to visually recognize the nozzle 41 from the side corresponding to the outer surface 643 of the support body 64, so that the visibility of the cleaning device 40 can be reduced.

[0130] The arrangement of the nozzle 41 is determined so that the ejected cleaning liquid W is deflected toward the light-transmitting cover 71 by a portion of the concave surface 644 . Fig.13 The arrow indicated by the double-dashed line in the middle indicates the path of the cleaning liquid W assumed to flow when not deflected by the concave surface 644. It is found that the cleaning liquid W not deflected by the concave surface 644 does not contribute to the cleaning of the light-transmitting cover 71 and is consumed. By determining the configuration of the nozzle 41 as described above, the utilization efficiency of the cleaning liquid W can be improved.

[0131] Fig.15 The appearance of the cleaning device 50 according to the fifth embodiment is shown as an example. Fig.16 As shown in the example in FIG. 5 , the cleaning device 50 is mounted on a support 65 to clean the lighting device 70. The support 65 may be a Figure 3 Components of a portion of vehicle 80 are illustrated in FIG.

[0132] like Fig.16 As shown in the example in FIG. 5 , the cleaning device 50 includes a nozzle 51. The cleaning device 50 is configured to spray the cleaning liquid W from the nozzle 51 toward the light-transmitting cover 71 to perform cleaning.

[0133] Fig.17 Example of edge Fig.16 The cleaning device 50 is a cross section taken along the line XVII-XVII in FIG. 5 as viewed from the direction of the arrows. The cleaning device 50 includes a joint 52. The joint 52 is configured to be connected to one end of a supply pipe (not shown) of the cleaning liquid W. The joint 52 includes a flow path 521 communicating with the supply pipe.

[0134] On the other hand, the nozzle 51 has an injection port 511 and a flow path 512. The flow path 512 is connected to the injection port 511. When the nozzle 51 is connected to the joint 52, the flow path 512 is connected to the flow path 521. Thus, a flow path for the cleaning liquid W to reach the injection port 511 from the supply pipe is formed. The cleaning liquid W is ejected from the injection port 511.

[0135] The cleaning device 50 has a bracket 53. The bracket 53 is configured to hold the nozzle 51 at a fixed position. In other words, the position of the nozzle 51 in the cleaning device 50 does not change, and is different from a cleaning device having a so-called pop-up nozzle.

[0136] The cleaning device 50 has an adhesive portion 54. The adhesive portion 54 bonds the bracket 53 to the inner surface 651 of the support body 65. That is, the cleaning device 50 is attached to the support body 65 from one side of the inner surface 651.

[0137] In this example, the adhesive portion 54 is implemented by a strip material having adhesive layers on both sides. One adhesive layer of the strip material is bonded to the supported surface 531 of the bracket 53 , and the other adhesive layer is bonded to the inner surface 651 of the support body 65 .

[0138] In addition, the bonding portion 54 may be realized by an adhesive applied when the cleaning device 50 is attached to the support body 65 .

[0139] like Fig.16 As shown in the example, the support body 65 has an opening 652. The opening 652 is formed adjacent to the light-transmitting cover 71 of the lighting device 70. If the cleaning device 50 is mounted on the support body 65, the nozzle 51 is configured to spray the cleaning liquid W through the opening 652 to the light-transmitting cover 71. On this basis, the nozzle 51 is configured so that at least a part of it is covered by the support body 65 when viewed from the side corresponding to the outer surface 653 of the support body 65.

[0140] More specifically, the opening 652 is formed so that the inner edge 652a faces the light-transmitting cover 71. In other words, there is no object that blocks the cleaning liquid W between the inner edge 652a and the light-transmitting cover 71.

[0141] In the structure involved in this embodiment, by a simple action of pressing the bracket 53 to the support body 65 from the side corresponding to the inner surface 651 of the support body 65, the bracket 53 and the inner surface 651 can be bonded by the bonding portion 54, and the cleaning device 50 can be mounted on the support body 65. It is unnecessary to perform work from the side corresponding to the outer surface 653 of the support body 65, so that the production equipment can be simplified and the productivity can be improved.

[0142] Furthermore, since the nozzle 51 and the light-transmitting cover 71 of the lighting device 70 can be directly opposed to each other through the opening 652 of the support body 65 , the degree of freedom in the positional relationship between the two can be increased.

[0143] On this basis, it is possible to make it difficult to visually identify the bracket 43 from the side corresponding to the outer surface 633 of the support body 65. In combination with the appearance that at least a portion of the nozzle 51 is covered by the support body 65 itself when viewed from the side corresponding to the outer surface 653 of the support body 65, the visual recognition of the cleaning device 50 is reduced.

[0144] Fig.18 The appearance of the cleaning device 90 according to the sixth embodiment as viewed from the front is shown. Fig.19 As shown in the example in FIG. 1 , the cleaning device 90 is a device mounted on the support body 69 to clean the lighting device 70. The support body 69 may be a Figure 3 Components of a portion of vehicle 80 are illustrated in FIG.

[0145] like Fig.19 As shown in the example in FIG. 8 , the cleaning device 90 includes a nozzle 91. The cleaning device 90 is configured to spray the cleaning liquid W from the nozzle 91 toward the light-transmitting cover 71 to perform cleaning.

[0146] Fig. 20 Example of edge Fig.19 The cleaning device 90 is a cross section viewed from the arrow direction along the line XX-XX. The cleaning device 90 includes a joint 92. The joint 92 is configured to be connected to one end of a supply pipe (not shown) of the cleaning liquid W. The joint 92 includes a flow path communicating with the supply pipe.

[0147] On the other hand, the nozzle 91 has an injection port 911 and a flow path. The flow path is connected to the injection port 911. If the nozzle 91 is connected to the joint 92, the flow paths are connected to each other. Thus, a flow path for the cleaning liquid W to reach the injection port 911 from the supply pipe is formed. The cleaning liquid W is ejected from the injection port 911.

[0148] The cleaning device 90 has a bracket 93. The bracket 93 is configured to hold the nozzle 91 at a fixed position. In other words, the position of the nozzle 91 in the cleaning device 90 does not change, and is different from a cleaning device having a so-called pop-up nozzle.

[0149] like Fig.18 As shown in the example in FIG. 1 , the cleaning device 90 has an adhesive portion 94. Fig. 20 As shown in the example in FIG. 8 , the bonding portion 94 bonds the bracket 93 to the inner surface 691 of the support body 69. That is, the cleaning device 90 is attached to the support body 69 from one side of the inner surface 691.

[0150] In this example, the adhesive portion 94 is implemented by a strip material having adhesive layers on both sides. One adhesive layer of the strip material is bonded to the supported surface 931 of the bracket 93 , and the other adhesive layer is bonded to the inner surface 691 of the support body 69 .

[0151] In addition, the bonding portion 94 may be realized by an adhesive applied when the cleaning device 90 is attached to the support body 69 .

[0152] like Fig.18 As shown in the example in FIG. 9 , the bracket 93 has a guide portion 932 and a cover 933. Fig.19 and Fig. 20 As shown in the example in FIG. 6 , an opening 692 is formed in the support body 69 . When the cleaning device 90 is attached to the support body 69 , the guide portion 932 and the cover 933 are exposed to the side corresponding to the outer surface 693 of the support body 69 through the opening 692 .

[0153] like Fig.18 and Fig.19 As shown in the example in FIG. 8 , the guide portion 932 has a concave surface 932 a . The concave surface 932 a has a size and a shape capable of guiding the cleaning liquid W ejected from the nozzle 91 toward the light-transmitting cover 71 .

[0154] The cover 933 is formed so as to cover at least a portion of the nozzle 91 when viewed from the side corresponding to the outer surface 693 of the support body 69 .

[0155] like Fig.19 and Fig. 20 As shown in the example in FIG. 6 , the outer edge 932b of the guide portion 932 and the outer edge 933a of the cover 933 are located inside the inner edge 692a of the opening 692. Therefore, by a simple operation of passing the guide portion 932 and the cover 933 through the opening 692 from the side corresponding to the inner surface 691 of the support body 69, the bracket 93 and the inner surface 691 can be bonded by the bonding portion 94, and the cleaning device 90 can be mounted on the support body 69. Since the operation from the side corresponding to the outer surface 693 of the support body 69 is not required, the production equipment can be simplified and the productivity can be improved.

[0156] On this basis, the size of the portion of the bracket 93 exposed to the side corresponding to the outer surface 693 of the support body 69 through the opening 692 can be reduced. In combination with the appearance that at least a portion of the nozzle 91 is covered by the cover 933 when viewed from the side corresponding to the outer surface 693, the visual recognition of the cleaning device 90 can be reduced.

[0157] like Fig.18 and Fig. 20As shown in the example in FIG. 2 , a plurality of openings 934 are formed in the bracket 93 . Each opening 934 is a through hole having a size that allows the washing liquid W to pass through. Each opening 934 connects the side of the bracket 93 facing the outside of the support body 69 and the side facing the inside.

[0158] Each opening 934 is arranged so as to be covered by the support body 69 when the cleaning device 90 is attached to the support body 69. An opening 934a, which is one of the plurality of openings 934, is arranged at a position including the vertically lower side of the nozzle 91.

[0159] A portion of the cleaning liquid W ejected toward the light-transmitting cover 71 of the lighting device 70 descends along the outer surface 693 of the support body 69 and can enter the opening 692. The returning cleaning liquid as described above may be accompanied by dust and dirt peeled off from the light-transmitting cover 71 by cleaning. The above-mentioned opening 934 is formed in the bracket 93, thereby facilitating the discharge of the returning cleaning liquid that has entered the opening 692. As a result, the following situation can be suppressed, that is, the dust and dirt that have entered the opening 692 together with the returning cleaning liquid are dried and fixed to the guide portion 932, thereby hindering the ejection of the cleaning liquid W from the nozzle 91.

[0160] On this basis, each opening 934 is configured to be covered by the support body 69, so that the visual recognition from the side corresponding to the outer surface 693 of the support body 69 can be reduced. As a result, the structure for discharging the return cleaning liquid entering the opening 692 can be suppressed from affecting the appearance of the cleaning device 90.

[0161] In this example, four openings 934 are formed. However, the number of openings 934 can be appropriately determined as long as they are formed at positions including the vertically lower side of the nozzle 91 (in other words, positions where the discharge efficiency is the highest).

[0162] like Fig.18 and Fig.19 As shown in the example in FIG. 9 , the guide portion 932 may include a deflecting portion 932 c . The deflecting portion 932 c is formed as a wall that can deflect the traveling direction of the cleaning liquid W ejected from the nozzle 91 toward the light-transmitting cover 71 .

[0163] Fig.19 The arrow indicated by the double-dashed line in the middle indicates the path of the cleaning liquid W assumed when the deflection unit 932c is not present. It is found that the cleaning liquid W that is not deflected by the deflection unit 932c does not contribute to the cleaning of the light-transmitting cover 71 and is consumed. By providing the deflection unit 932c as shown in this example, the utilization efficiency of the cleaning liquid W can be improved.

[0164] Fig.21 Example from edge Fig. 20The appearance of the cleaning device 90 viewed from the direction of arrow XXI in FIG. A plurality of openings 935 are formed in the deflection portion 932c. Each opening 935 is opposite to the concave surface 932a of the guide portion 932. Each opening 935 is a through hole having a size that allows the cleaning liquid W to pass through. Each opening 935 connects the side of the bracket 93 that is opposite to the outside of the support body 69 and the side that is opposite to the inside.

[0165] According to the above structure, it is possible to further promote the discharge of the return cleaning liquid that has entered the opening 692. On this basis, each opening 935 is formed at a position that is not easily visually recognized when the cleaning device 90 is viewed from the front, so that the structure for discharging the return cleaning liquid can suppress the influence on the appearance of the cleaning device 90.

[0166] In this example, two openings 935 are formed. However, the number of openings 935 can be appropriately determined. When only one opening 935 is formed, the opening is preferably arranged below the nozzle 91 and at a position opposite to the concave surface 932a. In addition, when the opening 935 is formed, the aforementioned opening 934 can be omitted.

[0167] The above-described embodiments are merely examples for facilitating understanding of the present invention. The configurations of the above-described embodiments can be appropriately modified or combined with other embodiments without departing from the gist of the present invention.

[0168] For example, at least one of the opening 934 and the opening 935 of the cleaning device 90 of the sixth embodiment can be formed respectively on the bracket 13 of the cleaning device 10 of the first embodiment, the bracket 23 of the cleaning device 20 of the second embodiment, and the bracket 33 of the cleaning device 30 of the third embodiment.

[0169] The object cleaned by the cleaning device according to each embodiment is not limited to the light-transmitting cover 71 of the lighting device 70. Examples of other objects include the detection surface of a sensor that detects information about the surroundings of the vehicle 80 using light or the surface of a member through which the light passes.

[0170] When cleaning an object, liquid such as water or gas such as air can be used. The liquid and gas are examples of fluids.

[0171] The cleaning device according to each embodiment may be mounted on a mobile body other than a vehicle. Examples of other mobile bodies include airplanes, aircraft, ships, etc. The mobile body may not require a driver.

[0172] The cleaning device according to each embodiment is not required to be mounted on a mobile body. For example, the cleaning device according to each embodiment can be installed in a house, a facility, a transportation infrastructure, etc., and used to clean the above-mentioned exemplified objects.
