Description

  The present invention relates to a mounting device for a vehicle-mounted camera, for example, a mounting device such as a drive recorder or a stereo camera for preventing a collision with a preceding vehicle.

  A mounting structure as a background art of this technical field is mounted on a vehicle and has a predetermined length formed by laterally extending a pair of left and right cameras for photographing a road environment ahead of the vehicle during traveling. A pair of left and right cameras are installed on the vehicle body by attaching them to each end of the chassis one by one, forming a mounting seat in the center of the chassis, and fixing the mounting seat to a predetermined mounting position on the vehicle body However, a portion other than the mounting seat portion of the chassis is in a state of being separated from the vehicle body (see, for example, Patent Document 1).

  In addition, an in-vehicle camera device as another background art is an in-vehicle camera device that is mounted on a vehicle and images a traveling environment in front of the vehicle, and includes a base member attached to the inside of the front window glass of the vehicle, and a base member It is characterized by comprising a fixed in-vehicle camera and a rear confirmation mirror fixed to the base member (see, for example, Patent Document 2).

  The in-vehicle image processing camera needs to be installed as parallel as possible to the vehicle axis parallel to the vehicle traveling direction in order to correctly recognize the situation in front of the vehicle. Moreover, it is necessary to arrange | position so that the angle of view of a vehicle-mounted image processing camera may enter in a wiper wiping area so that the image | photographed image may not deteriorate.

  In recent years, there is an increasing need for technologies such as sign detection and signal detection. In order to detect a sign, it is necessary to recognize a sign in a plurality of lanes. Further, in the signal detection, if the signal is to be recognized when stopping at the intersection or when entering the intersection, the angle of view must be expanded upward.

  Due to the above needs, the angle of view of the image processing camera has become wider than before. If an attempt is made to arrange the entire field of view range so as to be within the wiper wiping area, it is necessary to install the camera as close to the window as possible.

  On the other hand, among the in-vehicle image processing cameras, in the case of a camera having an imaging unit at each end of the stay (hereinafter referred to as a stereo camera), in order to increase the measurement accuracy, the relative positional accuracy of the left and right imaging units It is necessary to increase the height of the stay, and the stay has to increase the rigidity. Therefore, it is desirable to fix to the front rail part which can be screw-fastened reliably.

  However, when the vehicle-mounted camera is attached to both ends of the chassis (front rail) with the configuration as described in Patent Document 1, the amount of protrusion downward from the fixed point increases, and the view from the driver is blocked. In particular, in recent years, the inclination angle of the windshield has become shallow for the purpose of improving fuel efficiency, and the front and rear lengths of the windshield have become longer. For that reason, the windshield has come close to the driver's head. In such a car shape, the front rail will be placed closer to the driver's head than before, and if a stereo camera is attached to the front rail, there will be a problem that the driver will feel more disturbed than before .

  In order to meet all the above mounting requirements without obstructing the driver's field of view, it is optimal to place the camera in front of the front rail. However, with this arrangement, the center of gravity of the camera is considerably forward with respect to the fixed point of the front rail, so vibration resistance during vehicle travel becomes a problem. In order to compensate for this, if the plate or the camera housing has a structure resistant to vibration, the shape becomes complicated and the weight increases.

  On the other hand, as described in Patent Document 2, a method of attaching an in-vehicle camera to a window glass is also conceivable. However, in this case, it is not reliable to attach a heavy object like a stereo camera. In addition, since the window glass is interposed between the front rail and the camera, there is a problem that the installation accuracy is lowered as compared with the case of attaching to the front rail.

  The present invention has been made in view of such problems, and the object of the present invention is simple and lightweight, can be configured with a slight increase in weight, and does not vibrate during travel. An object of the present invention is to provide an in-vehicle camera mounting device that is stable in mounting on a vehicle body. In particular, an object of the present invention is to provide an in-vehicle camera mounting apparatus suitable for mounting a heavy weight stereo camera. It is another object of the present invention to provide an in-vehicle camera mounting device that can prevent an increase in temperature when direct sunlight hits the in-vehicle camera through the front window and can improve the appearance inside the vehicle.

  In order to achieve the above object, an in-vehicle camera mounting apparatus according to the present invention is an in-vehicle camera mounting apparatus that mounts an in-vehicle camera that takes an image of the front of a vehicle through the windshield of the vehicle inside the windshield. The support plate is disposed along the windshield, and one end of the support plate is fixed to the front rail located around the windshield, and the other end is fixed to the windshield. Has a box-shaped portion for housing the vehicle-mounted camera, and the vehicle-mounted camera is fixed in the box-shaped portion.

  In the in-vehicle camera mounting device of the present invention configured as described above, one end of the support plate is fixed to the front rail located around the windshield and is disposed along the windshield, and the other end of the support plate is the front Since it fixes to glass, since the both ends of the front-back direction are fixed, a fixed state is stabilized. And since a vehicle-mounted camera is fixed to the intermediate part of a support plate, a vibration is suppressed, a structure is simple and it can reduce in weight. In addition, since the in-vehicle camera is housed in the box-shaped portion of the support plate and fixed in the box-shaped portion, the temperature rise due to direct sunlight passing through the windshield can be prevented, and the appearance can be improved.

  The mounting device for the in-vehicle camera of the present invention can be reduced in weight with a simple configuration, and can be mounted at an optimal position where the angle of view of the in-vehicle camera enters the wiper wiping area, and can be mounted with high vibration resistance. In addition, since the placement of the in-vehicle camera is attached to the optimal position, the in-vehicle camera is less disturbed when viewed from inside the vehicle. Furthermore, it is possible to prevent a temperature rise when direct sunlight hits the vehicle-mounted camera through the front window, and to improve the appearance inside the vehicle by covering the vehicle-mounted camera with a box-shaped part.

Embodiments of an in-vehicle camera mounting device according to the present invention will be described below in detail with reference to the drawings. 1 is a perspective view of an in-vehicle camera mounting device according to a first embodiment, where (a) is a perspective view seen from outside a vehicle compartment around a position where a rear-view mirror of a vehicle front part is attached, and (b) is a vehicle interior. FIG. 2 shows a tapered plate used in FIG. 1, (a) is a perspective view seen from above, and (b) is a perspective view seen from below.

  With reference to FIGS. 1 and 2, the first embodiment of the in-vehicle camera mounting device according to the present invention will be described in detail. First, a description will be given of a configuration in the vicinity of a windshield of a vehicle to which the in-vehicle camera mounting device of the first embodiment is attached. The vehicle 1 includes a front rail 2 as a vehicle body constituent member extending in the vehicle width direction. The front rail 2 extends in a direction perpendicular to the longitudinal axis of the vehicle body, is made of a metal plate having a closed cross section, and is positioned above and behind the windshield. A windshield 3 is disposed in front of the front rail 2, and is fixed in a waterproof state with a waterproof member (not shown) sandwiched in an opening at the front of the vehicle body. A mirror base 4 is fixed to the windshield 3 by bonding or the like, and a rearview mirror 5 for viewing the rear is attached to the mirror base 4.

  The in-vehicle camera mounting device 10 according to the first embodiment mounts a camera 6 for photographing the front of the vehicle through the windshield 3 of the vehicle inside the windshield 3. The in-vehicle camera of the present embodiment is a stereo camera 6 having a pair of left and right camera parts 6a and 6b, and is attached to both ends of a stay 7 having a predetermined length extending in the direction of the front rail 2, that is, in the vehicle width direction. Two camera parts 6a and 6b are fixed. A fixing portion 8 for fixing the stereo camera 6 is formed at the center position of the stay 7.

  The in-vehicle camera mounting apparatus 10 includes a tapered plate 11 as a support plate. The taper plate 11 is disposed in an inclined state along the windshield 3, and one end thereof is fixed to the front rail 2 located around the windshield. That is, the taper plate 11 is formed of a metal plate extending in the front-rear direction of the vehicle body, and one end portion on the rear side of the vehicle is a first fixing portion 12 fixed to the front rail 2, and the other end portion on the front side of the vehicle. Is a second fixing portion 13 fixed to the windshield 3. And the intermediate part of the taper plate 3 becomes the 3rd fixing | fixed part 14 to which the stereo camera 6 is fixed. The second fixing portion 13 is fixed to the mirror base 4 as a receiving member fixed to the windshield 2.

  The taper plate 11 is bent downward at a portion of the first fixing portion 12 at the rear, and when the taper plate 11 is fixed to the front rail 2 by the first fixing portion 12, The third fixing portion 14 is configured to be parallel to the windshield 3. The taper plate 11 has a first fixing portion 12 fixed to the front rail 2 as a wide parallel portion, and has a taper that gradually decreases in width toward the front side. Since the taper plate 11 is supported at both ends so that the front and rear ends are supported and fixed, it does not require a large strength compared to a cantilevered support member, can be reduced in weight with a simple structure, and is not limited to metal but made of resin. It can also be.

  As shown in FIG. 2, the taper plate 11 fixes the front rail 2 and the taper plate 11 to the first fixing portion 12 with high accuracy, and fixes the taper plate 11 to the front rail 2. A screw hole 16 is formed. The second fixing portion 13 on the front end side is formed with a screw hole 17 for fixing a fixing point such as a mirror base 4 installed on the windshield 3 and the front side of the taper plate 11, and the third third portion in the center. The fixing portion 14 is formed with a screw hole 18 for fixing the taper plate 11 and the stereo camera 6.

  When the stereo camera 6 tries to correctly recognize the position of a vehicle, a pedestrian, a signal, a sign, etc. in the vehicle traveling direction, the stereo camera 6 is attached to the vehicle as much as possible with an axis parallel to the vehicle traveling direction (hereinafter referred to as the vehicle axis). It is preferable to install the stereo camera 6 with the shooting direction of the stereo camera 6 parallel or shifted by a target angle. The direction of the vehicle axis is determined by a hole provided in the front rail 2. Therefore, the shooting direction of the stereo camera 6 can be accurately fixed in a desired direction by fitting the hole prepared in the front rail 2 and the locator pin 15 prepared in the taper plate 11.

  In FIG. 2A, the locator pin 15 is provided on the taper plate 11 side, but a locator pin may be provided on the front rail side and a hole for receiving the locator pin may be provided on the taper plate 11. A locator pin may be provided in the second fixing portion 13 fixed to the windshield 3, and a hole for fitting with the locator pin may be provided in the mirror base 4 attached to the windshield 3.

  Further, as described above, in order to fix the stereo camera 6 to the taper plate 11 in a desired shooting direction, it is necessary to position the stereo camera 6 and the taper plate 11 with high accuracy. Therefore, the taper plate 11 and the third fixing portion 14 of the stereo camera 6 are provided with a locator pin 19 on the taper plate 11 protruding downward, for example, in addition to the screw hole 18 for fixing, so that the stay on the stereo camera 6 side is provided. 7 may be provided with a hole for fitting with the locator pin. Conversely, a locator pin may protrude from the fixing portion 8 of the stay 7 to form a hole that fits into the taper plate 11.

  As a method for fixing the taper plate 11 to the front rail 2 in a desired direction, as shown in FIG. 2, a groove 20 along the longitudinal direction may be provided. A protrusion having the same shape as the groove 20 as shown in FIG. In addition, as a method of fixing the stereo camera 6 and the taper plate 11 in a desired direction, the groove and the protrusion may be used. By providing the groove 20 along the longitudinal direction in the center of the taper plate 11, the strength of the taper plate 11 can be improved.

  In recent years, many of the room mirrors 5 have an illuminance sensor or the like that measures the illuminance of the front and rear. Wiring for supplying power to devices such as sensors installed in the rearview mirror 5 is led out to the front rail 2 side through the groove 20 of the taper plate 11 so that the wiring can be easily routed and a wiring cover is required. Disappear.

  Next, fixing of the front end side (vehicle front side) of the taper plate 11 will be described with reference to FIG. FIG. 3 shows the fixing portion 13 of the taper plate 11 on the windshield 3 side. When the windshield 3 and the front end of the taper plate 11 are fixed, a base for fixing the end is provided on the windshield 3. The base may be integrated with the mirror base 4. In this embodiment, the other end (front end) of the taper plate 11 is fixed by the mirror base 4. When the other end portion of the taper plate 11 and the mirror base 4 are separate, the design can be enhanced by covering the fixed end with the mirror base 4. And the stereo camera 6 is fixed to the taper plate 11 to which the front end part was fixed, and the stereo camera 6 images the vehicle traveling direction. The stereo camera 6 may be fixed in the direction in which the vehicle interior is photographed.

  In this embodiment, the mirror base 4 is fixed to the windshield 3 by adhesion, and the upper surface (contact surface with the windshield 3) 4a (indicated by a two-dot chain parallel oblique line) of the mirror base 4 is tapered. A stepped portion 4b into which the tip end portion (the other end portion) of the plate 11 is inserted is formed. The taper plate 11 is formed with a groove portion 20 along the longitudinal direction, and a deep portion 4c into which the groove portion 20 is inserted is formed at the center of the step portion 4b. The depth of the stepped portion 4 b corresponds to the thickness t of the tapered plate 11, and the depth of the deep portion 4 c corresponds to the thickness T of the groove portion 20. Moreover, the width W of the groove part 20 and the width w of the deep part 4c are formed equally. In a state where the mirror base 4 is attached to the windshield 3, an opening of the stepped portion 4 b and the deep portion 4 c is formed between the lower surface (inner side surface) of the windshield 3 and the upper surface of the mirror base 4, and a tapered plate is formed in this opening. 11 can be inserted.

  The mirror base 4 and the taper plate 11 may be fixed by screwing, or the tip of the taper plate 11 may be inserted between the mirror base 4 and the windshield 3 as shown in FIG. Alternatively, the tip of the taper plate 11 may be inserted into the stepped portion 4b and the deep portion 4c of the mirror base 4, and a screw may be inserted into the screw hole 17 at the tip of the taper plate 11 to be used together with screwing.

  In the first embodiment, what is most desired to be suppressed by the taper plate 11 is the vertical fluctuation of the stereo camera 6 caused by the vertical vibration when the vehicle is mounted, and therefore, between the mirror base 4 and the windshield 3 as shown in FIG. The taper plate 11 is inserted and fixed with screws using the screw holes 17 provided in the taper plate 11. As shown in FIG. 3B, the tip of the taper plate 11 may be inserted and fixed.

  Even when the tip of the taper plate 11 is not inserted between the windshield 3 and the mirror base 4, a method of providing a hole in the mirror base 4 itself and inserting the tip of the taper plate 11 into the hole may be used. When the fixing of the tip side of the taper plate 11 is shared with the mirror base 4, the mirror base 4 is attached to the windshield 3 and the windshield 3 is attached to the vehicle body. However, in this case, in order to absorb it, one or more receiving holes on the plate side are provided by making it a long hole, or in the case of the shape as shown in FIG. By providing the spaces 4d and 4e that allow the positional deviation, the positional deviation can be absorbed without changing the direction of the tapered plate 11.

  When the groove part 20 is formed in the taper plate 11 and the groove part 20 is fitted into the deep part 4c in the step part 4b of the mirror base 4, the mirror base 4 and the taper plate 11 are positioned in the left-right direction (vehicle width direction). It is suitable for. Since the taper plate 11 has two fixing points on the front and rear sides, the plate strength can be reduced as compared with the cantilever single point fixing. Therefore, the taper plate 11 may be a sheet metal or a resin. When made of resin, the weight of the plate itself can be reduced, which is more advantageous for vibration.

  Next, a modification of the tapered plate will be described with reference to FIG. The taper plate 11A shown in FIG. 4 includes angle adjusting mechanisms 21 and 22 at two points along the entire length in the longitudinal direction. In FIG. 4A, the angle adjustment mechanism is shown schematically. The angle adjustment mechanism 22 is installed between the first fixing portion 23 on the front rail 2 side and the intermediate third fixing portion 25 that fixes the stereo camera 6. The angle adjusting mechanism 21 is installed between the intermediate third fixing portion 25 and the second fixing portion 24 on the distal end side. The angle adjustment mechanism has the same configuration as the hinge mechanism, and can change the angles of the three fixing portions.

  The angle of the windshield differs depending on the vehicle type, and the angle of the bent portion of the tapered plate needs to be changed accordingly. In particular, in recent years, the angle of the windshield of passenger cars has become shallower in order to improve fuel efficiency, and the angle is around 20 degrees. On the other hand, in a car with a high vehicle height such as a sports multipurpose vehicle (SUV) or a small vehicle, the angle of the windshield is deep, and the angle is around 45 degrees. The angle adjusting mechanisms 21 and 22 are used so as to be able to cope with all the vehicle types in which the angles of these windshields are different.

  The angle can be adjusted only by the angle adjusting mechanism 21 on the windshield 3 side. However, in order to efficiently place the stereo camera 6 between the windshield 3 and the front rail 2, the angle is also adjusted on the front rail 2 side. It also preferably has a mechanism 22. By using the two angle adjusting mechanisms 21 and 22, the stereo camera 6 can be stably attached in correspondence with the angle and the curved state of the windshield.

  The tapered plate 11A having two angle adjusting mechanisms is basically composed of three members. That is, the front end member 24 that is positioned forward and constitutes the second fixing portion, the intermediate member 25 that is positioned in the middle and that constitutes the third fixing portion, and the rear member that is located rearward and constitutes the first fixing portion 23. Since the angle adjustment mechanisms 21 and 22 have substantially the same configuration, the rear angle adjustment mechanism 22 will be described in detail. The angle adjustment mechanism 22 connects the intermediate member 25 and the rear member 23 so as to be able to swing, and includes two bearing portions 26 and 26 formed at the front end portion of the rear member 23, and a rear portion of the intermediate member 25. One bearing portion 27 formed at the end portion is connected through a connecting shaft 28.

  A locking nut 29 is screwed onto the tip of the connecting shaft 28, and by tightening the locking nut 29, the bearing portions 26 and 26 of the rear member 23 and the bearing portion 27 of the intermediate member 25 can be fixed at an arbitrary angle. It has a configuration. In the tapered plate 11A configured as described above, even when the angle of the windshield 3 of the vehicle is shallow or deep, it is stable between the front rail 2 and the windshield 3 by adjusting the angle adjusting mechanisms 21 and 22. The vehicle-mounted camera 6 can be attached stably.

[Example 2]
As shown in FIG. 5, the in-vehicle camera mounting device 10 </ b> A according to the second embodiment is different from the first embodiment in the shape of the tapered plate. In addition, about the structure substantially the same as Example 1, the same code | symbol is attached | subjected and description is abbreviate | omitted. The taper plate 11B according to the second embodiment has an end portion on the front side of the vehicle that is bifurcated, and two fixing portions 31 and 32 are formed. In the illustrated example, the two fixing portions 31 and 32 are fixed directly to the windshield 3 by bonding or the like, but two bases (not shown) are fixed to the windshield, and the fixed portions 31 and 32 are fixed to the fixed base. 32 may be fixed by screwing or the like.

  In the taper plate 11B of the second embodiment, the fixed state of the taper plate can be further stabilized by widening the interval between the fixing points on the windshield 3 side, and the fixed state of the stereo camera 6 is also more stable. Further, when the fixed point is separated from the support of the room mirror 5 and the mirror base 4, the mirror base 4 can be disposed away. Furthermore, by expanding the interval between the fixed points, it is possible to reduce displacement with respect to the force applied in the left-right direction on the tip side of the taper plate 11B.

[Example 3]
As shown in FIG. 6, the in-vehicle camera mounting device 10 </ b> B of the third embodiment is different from the first and second embodiments in the shape of the first fixed portion on the vehicle rear side of the tapered plate 11 </ b> C. In the taper plate 11C, the first fixing portion on the front rail 2 side is formed in a bifurcated manner, and two fixing portions 33 and 34 are formed.

  In the taper plate 11C of the third embodiment, the fixed state of the taper plate can be further stabilized by widening the interval between the fixing points on the front rail 2 side, and the fixed state of the stereo camera 6 is also more stable. Further, it is possible to arrange the tapered plate 11C while avoiding the illumination and the sunglasses storage part arranged on the front rail 2 side. Furthermore, by increasing the interval between the fixed points, it is possible to reduce the displacement with respect to the force applied in the left-right direction on the rear side of the taper plate 11C.

[Example 4]
As shown in FIG. 7, the in-vehicle camera mounting device 10 </ b> C according to the fourth embodiment is different from the other embodiments in the shape of the tapered plate. In addition, about the structure substantially the same as Example 1, the same code | symbol is attached | subjected and description is abbreviate | omitted. In the taper plate 11D of the fourth embodiment, the end portion on the vehicle front side is formed in a bifurcated manner, two fixing portions 35 and 36 are formed, and the first fixing portion on the vehicle rear side is also formed in a bifurcated portion. The fixing portions 37 and 38 are formed. In the illustrated example, the two fixing portions 35 and 36 are fixed directly to the windshield 3 by adhesion or the like, but two bases (not shown) are fixed to the windshield, and the fixed portions 35 and 36 are fixed to the fixed base. 36 may be fixed by screwing or the like.

  In the taper plate 11D of the fourth embodiment, the front and rear end portions of the taper plate are formed in two forks, the front end portion is fixed at two points, and the rear end portion is also fixed at two points, so that the fixed state is more stable. In addition, the fixed state of the stereo camera 6 is also stabilized. That is, by increasing the interval between the fixed points, the displacement with respect to the force applied in the left-right direction can be reduced. In this case, in FIGS. 5 and 6, when a lateral force is applied to the taper plate, the stereo camera 6 is displaced to be twisted because the front-rear balance is poor. Therefore, in both the front rail 2 side and the windshield 3 side, the distance between the two fixed points is widened to minimize the displacement of the stereo camera 6 with respect to the left-right direction, and torsion occurs even when the displacement occurs. It is possible to make the structure difficult to do.

[Example 5]
Next, a fifth embodiment of the in-vehicle camera mounting device will be described with reference to FIGS. The fifth embodiment is characterized in that the tapered plate has a shape that takes into account the design. As shown in FIGS. 8 and 9, when the in-vehicle camera mounting device 10 </ b> D is viewed from the outside of the passenger compartment through the windshield 3, part or all of the casing excluding the field angle range of the stereo camera 6. The taper plate 11E is provided with light-shielding portions 40 and 40 that cover the upper part of the stereo camera. In the taper plate 11E of this embodiment, the light shielding portions 40, 40 are formed in a rectangular shape extending in the vehicle width direction from the central portion which is a third fixed portion to which the stereo camera 6 is attached.

  In FIG. 1, the taper plate 11 is disposed on the upper side in the central portion of the stereo camera 6. However, when the stereo camera 6 is viewed from outside the passenger compartment, most of the casing shape is visible. Normally, a light shielding area is provided on the windshield 3 side so that the stereo camera 6 cannot be seen from the outside of the passenger compartment. However, in FIGS. The housing of the stereo camera 6 can be covered by the light shielding portions 40 and 40.

  As a result, the shading area of the windshield of the vehicle to which the in-vehicle camera is normally attached must be provided so as to avoid the angle of view of the in-vehicle camera, and a different windshield from the vehicle to which the in-vehicle camera is not attached must be used. It is only necessary to provide one type of windshield shading region for each vehicle type.

  The color of the taper plate 11E in FIGS. 8 and 9 is preferably black in order to serve as a light shielding region. Further, since the width of the taper plate 11E is increased, the material may be a resin in order to reduce the weight. Furthermore, since the shape of the taper plate 11E prevents direct sunlight from hitting the stereo camera 6, there is an effect of suppressing an increase in the casing temperature of the stereo camera 6.

  The taper plate may be disposed on the lower side and the side surface of the stereo camera 6 so as to cover the range other than the angle of view range of the stereo camera 6 as in the modification of the fifth embodiment shown in FIG. As a result, a conventional taper plate component can compensate for two components that conventionally required a plate for fixing the stereo camera 6 and a design cover that covers the camera.

  The taper plate 11 </ b> F illustrated in FIG. 10 includes a cover portion located below the stereo camera 6. The taper plate 11F includes an upper plate portion 41 as a light shielding portion, side plate portions 42 and 42, a lower plate portion 43 as a cover portion, and a rear plate portion 44, and is formed in a box shape having an open front. Has been. The stereo camera 6 is mounted in a box-shaped taper plate 11F, and is configured to be able to image the traveling direction of the vehicle from the front opening.

  The taper plate 11F is fixed to the front rail 2 with the first fixing portion 12 protruding from the box-shaped rear, and fixed to the mirror base 4 fixed to the windshield 3 with the second fixing portion 13 protruding forward. Is done. Then, the mounting portion 8 of the stay 7 of the stereo camera 6 is fixed to the upper plate portion 41 in the middle of the taper plate 11F, and the camera 6 is mounted and fixed in the box-shaped taper plate. In the modification of the fifth embodiment, the stereo camera 6 can avoid direct sunlight and can improve the appearance in the vehicle by covering the camera.

[Example 6]
Next, a sixth embodiment of the in-vehicle camera mounting device will be described with reference to FIG. In the in-vehicle camera mounting device 10F of the sixth embodiment, the taper plate 11G has a shape in which a vent hole 45 and a vent passage 46 are provided. As described above, when the stereo camera 6 is placed in an optimal arrangement, the temperature rise due to direct sunlight may be worse than when the stereo camera 6 is attached to the front rail 2. That is, since the stereo camera 6 is installed and fixed below the windshield 3 in front of the front rail 2, it receives direct sunlight.

  Further, even when the direct sunlight is not applied to the stereo camera 6, the temperature of the front rail 2 is increased by the direct sunlight being applied to the vehicle, and the temperature of the stereo camera 6 is finally increased through the taper plate. .

  Therefore, as shown in FIG. 11, a vent hole 45 and a vent passage 46 are provided in the taper plate 11G. Usually, the cooling air applied to the stereo camera 6 flows along the windshield 3 from below. Therefore, the cooling air can be taken in from the vent 45, and the temperature of the entire tapered plate 11G can be lowered through the vent passage 46. The greater the number of vents 45 and vents 46, the greater the cooling effect. Further, the larger the vent 45, the easier the cooling air can be taken.

  When the direction of the cooling air that hits the stereo camera 6 is from a direction other than the downward direction, for example, when blowing from behind, the vent 45 may be directed to the side that receives the cooling air. By appropriately providing the vent hole 45 and the vent path 46, the cooling air can be flowed along the taper plate 11G, the temperature rise of the taper plate can be suppressed, and the operation of the stereo camera 6 can be stabilized. .

  In addition, this invention is not limited to an above-described Example, Various modifications are included.
