Description

Technical Field

[0001] This invention relates to a camera holding structure for holding a vehicle-mounted camera. Background Technology

[0002] Typically, camera holding structures for holding vehicle-mounted cameras are known. For example, a camera holding structure includes a window that separates the vehicle's interior space from the vehicle's exterior space and a holding member that is fixed to the inner surface of the window and holds the vehicle-mounted camera.

[0003] For example, JP2020-98282A discloses a camera bracket for fixing an external environment detection camera to the inner surface of a windshield.

[0004] When the aforementioned retaining member is attached to the inner surface of the vehicle window using adhesives or the like, if the attachment position of the retaining member on the inner surface of the vehicle window deviates from the target position, the positional accuracy of the retaining member relative to the vehicle window will decrease, and the positional accuracy of the vehicle camera held by the retaining member may also decrease. Summary of the Invention

[0005] In view of the above background, the main objective of the present invention is to provide a camera holding structure that facilitates the precise attachment of a holding member to the inner surface of a vehicle window at a target location.

[0006] To achieve the above objectives, one aspect of the present invention provides a camera holding structure 17 for holding a vehicle-mounted camera 11, the camera holding structure comprising: a window 6 that separates a vehicle interior space SP1 from a vehicle exterior space SP2; and a holding member 16 fixed to the inner surface 6A of the window and holding the vehicle-mounted camera, wherein the holding member includes a fixing frame 19 fixed to the inner surface of the window and a cover 20 that protrudes from the fixing frame toward the interior of the vehicle and defines a field of view S of the vehicle-mounted camera on the vehicle interior side of the window, and the fixing frame has a facing surface 41 opposite to and attached to the inner surface of the window, the facing surface being provided with at least one marking portion 47, 51, 61, 71 visible from the exterior of the vehicle.

[0007] According to this aspect, the opposing surfaces of the retaining member's fixing frame can be attached to the inner surface of the vehicle window, while the position of the marking portion can be visually checked, thus preventing the attachment position of the retaining member on the inner surface of the vehicle window from deviating from the target position. Therefore, the positional accuracy of the retaining member and the vehicle-mounted camera relative to the vehicle window can be improved.

[0008] Preferably, the field of view space is located on the rear side of the vehicle window. The cover includes a left wall portion and a right wall portion 26 that respectively define the left and right portions of the field of view space, and a bottom wall portion 27 that connects the lower end portion of the left wall portion and the lower end portion of the right wall portion and defines the lower part of the field of view space. The upper surface of the bottom wall portion is provided with a stray light suppression structure 30 for suppressing stray light entering the vehicle camera. The stray light suppression structure has a plurality of ridges 31 arranged in the front-rear direction and extending in the left-right direction, and at least one marking portion extends in the left-right direction at the lower front side of the plurality of ridges.

[0009] Based on this, the consistency between the stray light suppression structure and the design of the relative surfaces can be enhanced, thereby improving the appearance of the vehicle.

[0010] Preferably, at least one marking portion includes a plurality of marking portions arranged at intervals in a direction perpendicular to the left-right direction, and the spacing between the plurality of marking portions is the same as the spacing between the plurality of ridges.

[0011] Based on this, the consistency between the stray light suppression structure and the design of the relative surfaces can be further enhanced, thereby further improving the appearance of the vehicle.

[0012] Preferably, the window includes a substrate layer 8 and a light-shielding layer 9. The substrate layer has transparency, and the light-shielding layer is stacked on a portion of the substrate layer and has a lower transparency than the substrate layer. The light-shielding layer is provided with an opening 10 for allowing light entering the field of vision to pass through the opening. The opposing surface includes a covering portion 43 and an exposed portion 44. When viewed from outside the vehicle, the covering portion is covered by the light-shielding layer, and when viewed from outside the vehicle, the exposed portion is located at a position corresponding to the opening and exposed from the light-shielding layer. At least a portion of at least one marking portion is provided on the exposed portion.

[0013] Based on this aspect, it is possible to attach the opposing surface to the inner surface of the window while visually inspecting the position of the marking portion relative to the opening of the light-blocking layer. Therefore, it is possible to more effectively prevent the attachment position of the retaining member on the inner surface of the window from deviating from the target position.

[0014] Preferably, the exposed portion extends from the left edge of the opening to the right edge in the left-right direction, and at least one marking portion is continuous from the left end to the right end of the exposed portion.

[0015] Based on this, the length of the marking part can be fully ensured, thus making it easy to visually check the position of the marking part.

[0016] In one embodiment, at least one marking portion may include recesses 47, 51 disposed on opposite surfaces.

[0017] According to this aspect, when the retaining member is subjected to thermal expansion, the recess can absorb the stress caused by the thermal expansion of the retaining member. Therefore, it is possible to prevent the reduction of the adhesion strength between the opposing surfaces and the inner surface of the window due to the thermal expansion of the retaining member.

[0018] In another embodiment, at least one marking portion may include a protrusion 61 disposed on an opposing surface.

[0019] In this respect, the protrusions strengthen the fixed frame, thereby increasing its rigidity. Therefore, deformation of the fixed frame can be suppressed.

[0020] In another embodiment, at least one marking portion may include a sprayed portion 71 painted with a color different from that of the opposite surface.

[0021] Based on this, markings can be formed without creating irregularities on the opposing surface itself. Therefore, the structural complexity of the retaining member caused by the formation of markings can be avoided.

[0022] Preferably, the opposing surfaces are attached to the inner surface of the window via a transparent adhesive.

[0023] According to this aspect, even when the adhesive is placed at a position overlapping the marking part, the position of the marking part can be fully seen from outside the vehicle via the adhesive.

[0024] Therefore, according to an aspect of the invention, a camera holding structure can be provided that facilitates precise attachment of the holding member to the inner surface of the window at a target location. Attached Figure Description

[0031] (Vehicle 1)

[0032] Below, we will refer to Figures 1 to 3 A vehicle 1 according to one embodiment of the present invention is described. Arrows Fr included in each figure indicate the forward direction of vehicle 1.

[0033] Reference Figure 1 Vehicle 1 is a four-wheeled automobile. Vehicle 1 includes a body 2 that extends in the longitudinal direction. An interior space SP1 is defined inside the body 2, and a plurality of seats 4 are arranged in the central part of the interior space SP1 in the longitudinal direction.

[0034] In the front of vehicle 1, a front window 6 (example of a window) is provided in front of multiple seats 4. The front window 6 separates the vehicle interior space SP1 from the vehicle exterior space SP2 (in this embodiment, the vehicle exterior space is the space in front of vehicle 1). The front window 6 is tilted upward and backward.

[0035] Reference Figure 2 and Figure 3 The front windshield 6 includes a substrate layer 8 and a light-shielding layer 9 superimposed on the central portion of the upper part of the substrate layer 8 from the interior of the vehicle. The substrate layer 8 is made of glass and is transparent. Note that in another embodiment, the substrate layer 8 may be made of a transparent material other than glass (e.g., a transparent resin). The light-shielding layer 9 is made of black ceramic printed on the inner surface of the substrate layer 8 and is opaque. Note that in another embodiment, the light-shielding layer 9 may be made of a material with a lower transparency than the substrate layer 8, in addition to black ceramic. The central portion of the light-shielding layer 9 is provided with an opening 10 having a substantially trapezoidal shape.

[0036] A front camera 11 (example of an in-vehicle camera) is installed at the upper rear of the front windshield 6. The front camera 11 is a device that captures images of the vehicle's exterior space SP2 from the vehicle's interior space SP1 via the front windshield 6. For example, the front camera 11 is a digital camera using a solid-state imaging element such as a CCD or CMOS. The front camera 11 is connected to a control unit 12 (see...). Figure 1 The control unit 12 is configured to perform advanced driver assistance controls (e.g., lane keeping control and forward vehicle following control) on the vehicle 1 based on image data transmitted from the front camera 11. (See reference...) Figure 2 The front camera 11 includes a lens 13 that converges light incident on it from the front and a camera body 14 that holds the lens 13. The lower part of the camera body 14 extends forward more than the upper part of the camera body 14.

[0037] Reference Figure 2 and Figure 3 A bracket 16 (an example of a retaining member) for holding the front camera 11 is fixed to the inner surface of the substrate layer 8 and the light-shielding layer 9 of the front window 6 (hereinafter referred to as "inner surface 6A of the front window 6"). The bracket 16 and the front window 6 cooperate to form a camera retaining structure 17.

[0038] The bracket 16 includes a fixed frame 19 fixed to the inner surface 6A of the front window 6 and a cover 20 protruding from the fixed frame 19 toward the rear lower side (the interior of the vehicle).

[0039] The mounting frame 19 of the bracket 16 is disposed along and attached to the inner surface 6A of the front window 6. Note that the attachment structure for attaching the mounting frame 19 to the inner surface 6A of the front window 6 will be described later.

[0040] The fixed frame 19 is a rectangular frame. The fixed frame 19 includes a front panel 22 extending in the left-right direction, a left side panel 22 extending rearward and upward from the front panel 22, and a right side panel 23 (in...). Figure 2 In the image, only the right side plate portion 23 is shown, as well as the rear plate portion 24, which extends in the left-right direction to connect the rear end portion of the left side plate portion and the rear end portion of the right side plate portion 23.

[0041] The cover 20 of the bracket 16 defines the field of view space S of the front camera 11 (hereinafter referred to as "field of view space S"). The field of view space S is a space for light from the external space SP2 of the vehicle to enter the lens 13 of the front camera 11, and is located on the rear side (inside the vehicle) of the front window 6. The field of view space S is located at a position corresponding to the opening 10 of the light shielding layer 9 of the front window 6, and light from the external space SP2 of the vehicle enters the field of view space S through the opening 10.

[0042] The cover 20 includes a left wall portion and a right wall portion 26 extending downward from the left side plate portion and the right side plate portion 23 of the fixed frame 19, a bottom wall portion 27 connecting the lower end portion of the left wall portion and the lower end portion of the right wall portion 26, and a rear wall portion 28 extending rearward and downward from the rear plate portion 24 of the fixed frame 19 and connecting the upper rear end portion of the left wall portion and the upper rear end portion of the right wall portion 26.

[0043] The left and right wall portions 26 of the cover 20 define the left and right portions of the field of view S, respectively. The left and right wall portions 26 are integrally formed with the fixed frame 19. The relative spacing between the left and right wall portions 26 widens from back to front.

[0044] The bottom wall portion 27 of the cover 20 defines the lower part of the field of view space S. The front part of the bottom wall portion 27 is opposite to the front window 6 in the vertical direction via a gap. The relative gap between the front part of the bottom wall portion 27 and the front window 6 becomes wider from front to rear. The lower part of the camera body 14 of the front camera 11 is mounted to the bottom wall portion 27 via a mounting mechanism (not shown in the figure).

[0045] The upper surface of the bottom wall portion 27 is provided with a stray light suppression structure 30 (also called a stray light shield (SLS)) for suppressing stray light (reflected light) entering the lens 13 of the front camera 11. For example, the stray light suppression structure 30 is constructed of a plurality of ridges 31 arranged continuously in the front-rear direction. Each ridge 31 extends linearly from the lower end of one of the left side wall portion and the right side wall portion 26 to the lower end of the other in the left-right direction. For example, each ridge 31 has an inverted V-shaped cross section.

[0046] The left and right sides 27A of the bottom wall portion 27 are integrally formed with the left and right side wall portions 26. The transverse central portion 27B of the bottom wall portion 27 is detachably mounted between the left and right sides 27A. A heater 33 for heating the windshield 6 is mounted on the lower surface of the transverse central portion 27B of the bottom wall portion 27. The heater 33 consists of multiple heating wires (not shown in the figure). The heater 33 is positioned directly above the lower part of the camera body 14 of the front camera 11.

[0047] The rear wall portion 28 of the cover 20 defines the upper rear part of the field of view space S. The rear wall portion 28 is integrally formed with the fixed frame 19. The rear wall portion 28 is positioned vertically opposite the rear portion of the bottom wall portion 27 via a gap. The relative gap between the rear wall portion 28 and the rear portion of the bottom wall portion 27 narrows from front to back. An entrance hole 35 is provided between the rear end portion of the rear wall portion 28 and the rear end portion of the bottom wall portion 27, and light from the field of view space S enters the lens 13 of the front camera 11 through the entrance hole 35.

[0048] (Attachment structure of fixed frame 19)

[0049] Next, the attachment structure for attaching the fixing frame 19 to the inner surface 6A of the front window 6 will be described in detail.

[0050] Reference Figure 2 and Figure 3The fixing frame 19 has an opposing surface 41 that is substantially parallel to the inner surface 6A of the windshield 6. Note that in other embodiments, the opposing surface 41 may not be substantially parallel to the inner surface 6A of the windshield 6. The opposing surface 41 may be a flat surface or may be partially or completely curved. The opposing surface 41 is attached to the inner surface 6A of the windshield 6 via an adhesive 42. When viewed from outside the vehicle, the adhesive 42 is covered by the sunshade 9 of the windshield 6. In other words, the adhesive 42 is located in a position not visible from outside the vehicle.

[0051] The opposing surfaces 41 of the fixed frame 19 include a covering portion 43 and an exposed portion 44. The covering portion 43 is constructed from the outer surface of the front portion of the front panel 22, the outer surface of the left side panel, the outer surface of the right side panel 23, and the outer surface of the rear panel 24. When viewed from outside the vehicle, the covering portion 43 is covered by the light-blocking layer 9 of the front window 6. In other words, the covering portion 43 is located in a position not visible from outside the vehicle. The exposed portion 44 is constructed from the outer surface of the rear portion of the front panel 22. The exposed portion 44 is located at a position corresponding to the opening 10 of the light-blocking layer 9 of the front window 6, and is exposed from the light-blocking layer 9 when viewed from outside the vehicle. In other words, the exposed portion 44 is located in a position visible from outside the vehicle. The exposed portion 44 extends from the left edge to the right edge of the opening 10 in a left-right direction.

[0052] A single recess 47 is provided on the front portion of the opposing surface 41 of the fixed frame 19 (the portion corresponding to the front plate portion 22). The recess 47 extends linearly in the left-right direction at a position on the lower front side of the plurality of ridges 31 of the stray light suppression structure 30. The width W of the recess 47 is the same as the spacing P of the plurality of ridges 31. However, in other embodiments, the width W of the recess 47 may be wider or narrower than the spacing P of the plurality of ridges 31.

[0053] The lateral central portion of the recess 47 is disposed on the exposed portion 44 of the opposing surface 41. In other words, the lateral central portion of the recess 47 is disposed at a position visible from outside the vehicle. The left and right ends of the recess 47 both extend to the covering portion 43 of the opposing surface 41. In other words, the recess 47 is continuous from the left end to the right end of the exposed portion 44. Note that in another embodiment, the entire recess 47 may be contained within the area of ​​the exposed portion 44.

[0054] The fixing frame 19 is provided with a connecting surface 48 that connects the exposed portion 44 of the opposing surface 41 to the upper surface of the bottom wall portion 27 of the cover 20 (i.e., the surface where the stray light suppression structure 30 is provided). No recess 47 is provided on the connecting surface 48. Therefore, the spacing between the front end ridge 31 and the recess 47 is wider than the spacing P of the plurality of ridges 31.

[0055] (Beneficial effects)

[0056] In this embodiment, the opposing surface 41 of the fixing frame 19 is provided with a recess 47 at a position visible from outside the vehicle. This allows the opposing surface 41 to be attached to the inner surface 6A of the windshield 6, while simultaneously visually inspecting the position of the recess 47, thus preventing the attachment position of the bracket 16 on the inner surface 6A of the windshield 6 from deviating from the target position. Therefore, the positional accuracy of the bracket 16 and the front camera 11 relative to the windshield 6 can be improved.

[0057] Furthermore, the stray light suppression structure 30 includes a plurality of ridges 31 arranged in the front-rear direction and extending in the left-right direction, and a recess 47 extends in the left-right direction at a position on the lower front side of the plurality of ridges 31. Therefore, the consistency of the design of the stray light suppression structure 30 and the opposing surface 41 can be improved, thereby improving the appearance of the vehicle 1.

[0058] Furthermore, the opposing surface 41 includes an exposed portion 44 located at a position corresponding to the opening 10 of the light-shielding layer 9, and a lateral central portion of a recess 47 is provided on the exposed portion 44. This allows the opposing surface 41 to be attached to the inner surface 6A of the windshield 6, while simultaneously visually inspecting the position of the recess 47 relative to the opening 10 of the light-shielding layer 9. Therefore, it is possible to more effectively prevent the attachment position of the bracket 16 on the inner surface 6A of the windshield 6 from deviating from the target position.

[0059] Furthermore, since the recess 47 is provided on the exposed portion 44 as described above, the design consistency between the stray light suppression structure 30 and the exposed portion 44 can be improved. Specifically, in this embodiment, the heater 33 is mounted on the lower surface of the bottom wall portion 27 of the cover 20, and the heater 33 is positioned directly above the lower part of the camera body 14 of the front camera 11. Due to this relationship, it is difficult to shift the position of the bottom wall portion 27 of the cover 20 downwards; therefore, the front end portion of the bottom wall portion 27 of the cover 20 is positioned at a relatively high position. As a result, the width of the exposed portion 44 in the vertical direction increases, and the exposed portion 44 becomes more noticeable from outside the vehicle. Therefore, the effect of improving the design consistency between the stray light suppression structure 30 and the exposed portion 44 as described above is significant.

[0060] Furthermore, the exposed portion 44 extends from the left end to the right end of the opening 10 in the left-right direction, and the recess 47 is continuous from the left end to the right end of the exposed portion 44. Therefore, the length of the recess 47 can be sufficiently ensured, and thus, the position of the recess 47 can be easily visually inspected.

[0061] Furthermore, the recess 47 can absorb the stress caused by the thermal expansion of the bracket 16, thus preventing a decrease in the adhesion strength between the opposing surface 41 and the inner surface 6A of the front window 6 caused by the thermal expansion of the bracket 16. In addition, by using the recess 47 as a marking part, the marking part can be formed at a relatively low cost.

[0062] (Revise)

[0063] Reference Figure 4 In the first modification of the above embodiment, the exposed portion 44 of the opposing surface 41 is provided with a plurality of recesses 51 (example of a marking portion). The plurality of recesses 51 are provided at intervals in a direction perpendicular to the left-right direction. The spacing P1 of the plurality of recesses 51 is the same as the spacing P2 of the plurality of ridges 31 of the stray light suppression structure 30. With this configuration, the consistency of the design of the stray light suppression structure 30 and the opposing surface 41 can be further improved, and therefore, the appearance of the vehicle 1 can be further improved.

[0064] In addition, refer to Figure 4 In the first modification of the above embodiment, not only are multiple recesses 51 provided on the exposed portion 44 of the opposing surface 41, but multiple recesses 52 are also provided on the connecting surface 48 that connects the exposed portion 44 of the opposing surface 41 to the upper surface of the bottom wall portion 27 of the cover 20. With this structure, the consistency of the design of the stray light suppression structure 30, the opposing surface 41, and the connecting surface 48 can be improved, thereby further improving the appearance of the vehicle 1.

[0065] In addition, refer to Figure 4 In the first modification of the above embodiment, a portion of the adhesive 42 is exposed from the light-shielding layer 9 when viewed from outside the vehicle. In other words, a portion of the adhesive 42 is positioned where it can be seen from outside the vehicle. In this case, it is preferable that the adhesive 42 is transparent. Thus, even when the adhesive 42 is positioned at a location overlapping with the plurality of recesses 51, the plurality of recesses 51 can be fully seen from outside the vehicle via the adhesive 42. Furthermore, even when the adhesive 42 is seen from outside the vehicle, it is unlikely to impair the appearance of the vehicle 1, thus simplifying the layout management of the adhesive 42.

[0066] Reference Figure 5 In the second modification of the above embodiment, instead of the recess 47, one or more protrusions 61 (examples of marking portions) are provided on the exposed portion 44 of the opposing surface 41. The protrusions 61 extend in the left-right direction and are continuous from the left end to the right end of the exposed portion 44. With this configuration, the protrusions 61 can strengthen the fixing frame 19, thus improving the rigidity of the fixing frame 19. As a result, deformation of the fixing frame 19 can be suppressed (in particular, deflection of the fixing frame 19 when the temperature of the fixing frame 19 becomes high, such as in summer). In addition, as the material of the support 16, an inexpensive resin material with relatively low rigidity can be used, which can reduce the material cost of the support 16. Furthermore, by using the protrusions 61 as marking portions, marking portions can be formed at a relatively low cost.

[0067] Reference Figure 6In the third modification of the above embodiment, instead of the recess 47, one or more sprayed portions 71 (examples of marking portions) are provided on the exposed portion 44 of the opposing surface 41. The sprayed portions 71 are sprayed with a color different from the color of the opposing surface 41. The sprayed portions 71 extend in the left-right direction and are continuous from the left end to the right end of the exposed portion 44. With this configuration, marking portions can be formed without creating irregularities on the opposing surface 41 itself. Therefore, the complexity of the structure of the support 16 due to the formation of marking portions can be avoided. Furthermore, by using the sprayed portions 71 as marking portions, marking portions can be formed at a relatively low cost.

[0068] In this embodiment, the front camera 11 is shown as an example of a vehicle-mounted camera, but in another embodiment, the rear camera or side camera (not shown in the figure) may be an example of a vehicle-mounted camera.

[0069] The specific embodiments of the present invention have been described above, but the present invention is not limited to the above embodiments and can be modified or varied in various ways.
