Description

  The present invention relates to a mounting bracket for mounting a vehicle-mounted peripheral monitoring device such as a camera or a radar to a vehicle body, and particularly relates to a mounting bracket for fixing a bracket holding a camera or the like to a license plate.

  In order to assist left and right safety checks at intersections with poor visibility or T-junctions, peripheral monitoring machines such as cameras and radars are attached and fixed to the vehicle. The bracket for mounting the perimeter monitor on the vehicle is generally formed by drilling a bracket that holds the perimeter monitor in a mounting portion of the vehicle body (for example, a bonnet, a front grill, a bumper, etc.) and using a mounting screw. Some are screwed and fixed.

  However, in this method, it takes time to drill a hole in the vehicle body mounting portion to which the perimeter monitoring machine is attached, and when the mounting portion is formed of a resin material or the like, there is a problem of strength and mounting accuracy. Quality issues come out. Moreover, since a hole is made in a mounting portion such as a bonnet, the vehicle is scratched, and the aesthetics and value of the vehicle are reduced. In addition, when a camera is used as the periphery monitoring device, there is a problem that the visibility in each direction is impaired if the fixing position of the camera to the vehicle body is significantly different from the viewpoint of the driver.

In order to solve these problems, various patents relating to a mounting bracket that uses a mounting hole of a license plate for a vehicle to fasten a perimeter monitor to the license plate have been proposed. For example, Japanese Patent Application Laid-Open No. 2004-122954 relates to a fixture for holding a vehicular CCD camera, and a main body portion that is fastened to a vehicle main body together with a license plate, and extends from the main body portion. And a holding part having a long hole that allows the CCD camera to be adjusted in the width direction.
JP 2004-122594 A

  According to the above-described conventional technology, the camera can be fixed to the vehicle by fastening together with the license plate. However, in this method, it takes time and effort to form a bracket for holding the periphery monitoring machine and fasten it together with the license plate, and depending on the vehicle type, the installation position of the license plate is not always located on the center line of the vehicle width. The left and right images taken by the camera are very different from the driver's viewpoint, and the visibility in each direction may be impaired. Thus, in order to ensure the visibility with a camera, it is desirable to adjust so that the fixed position of the said camera may be located on the center line of a vehicle width. In addition, in a device for mounting and fixing the camera to the vehicle body, the camera fixing position is within the range of road regulations (for example, in the case of a normal passenger car, the minimum ground clearance is 9 cm or more, and the protrusion dimension from the vehicle tip is within 3 cm. ) To adjust the fixed position of the camera. However, none of the above-described conventional technologies suggests the idea of restricting the camera fixing position within the road regulation range while adjusting the camera fixing position to be on the center line of the vehicle width.

  The present invention solves such a problem, and it is possible to easily attach a mounting bracket for mounting and fixing a camera to a license plate, and to adjust the fixing position of the camera. An object is to realize a mounting bracket.

  In order to achieve the above object, the present invention provides a mounting bracket to which a periphery monitoring machine can be attached to an end portion of a license plate of a vehicle, the clamping portion for clamping an uneven portion of the license plate, And a mounting surface for mounting the perimeter monitoring device, wherein the mounting surface is formed with an adjustment hole for adjusting the mounting position of the perimeter monitoring device.

  Further, the clamping portion is deformed to the license plate side by a fastening force of a fastening member inserted into the adjustment hole, and presses the license plate.

  A mounting bracket capable of mounting a periphery monitoring device on an end portion of a license plate of the vehicle, the mounting surface for mounting the periphery monitoring device, and a first clamping surface that presses the uneven portion of the license plate from the front side And a second clamping surface that presses the concavo-convex part of the license plate from the rear surface side, and a hinge part that is rotatable with respect to the second clamping surface in a direction separating the first clamping surface from the license plate. The hinge portion has a projecting piece projecting in a downward direction of the mounting surface, and the projecting piece causes the first clamping surface to be displaced when the first clamping surface is displaced toward the license plate. The license plate is biased in the plate direction, and the license plate is clamped between the first clamping surface and the second clamping surface.

  According to the present invention, there is no need for conventional screwing or drilling for screwing, and the camera can be easily attached to the vehicle.

FIG. 5 is a detailed sectional view of the in-vehicle camera. 6A and 6B are explanatory views showing a state in which the mounting bracket device 10 of the vehicle-mounted camera according to the first embodiment of the present invention is mounted upside down. FIG. 6A is an external view, and FIG.

  The mounting bracket device 10 for the in-vehicle camera of the first embodiment is mounted and fixed by using mounting screws (not shown) near the center of the bumper 3 of the vehicle body 1 as shown in FIGS. The mounting bracket 11 and the camera bracket 12 sandwich the license plate 2. The camera bracket 12 is engaged with the mounting bracket 11 by a mounting screw 15, and the mounting bracket 11 holds the license plate 2.

  As shown in FIG. 4, the camera bracket 12 is provided with mounting holes for attaching the camera 4 on both side surfaces formed by bending both ends at right angles in the same direction. On the bottom surface of the camera bracket 12, an engagement hole 12 a for inserting an attachment screw 15 for fixing to the attachment bracket 11 is formed.

  The mounting bracket 11 is integrally formed of an elastic material (metal or the like). As shown in FIG. 4, the mounting bracket 11 is formed with a clamping portion 11 e that is bent at an end portion and clamps the mounting surface 11 a for attaching the camera bracket 12 and the uneven portion 2 b of the license plate 2. The sandwiching portion 11e is provided at the upper and lower end portions of the mounting bracket 11 so as to correspond to the position of the uneven portion 2b of the license plate 2, and is formed, for example, in the same uneven shape as the uneven portion 2b of the license plate 2. .

  The attachment surface 11a is provided with an engagement hole 11g through which an attachment screw 15 for fixing the camera bracket 12 is inserted. The engagement hole 11g is formed in a long hole shape in order to adjust the position of the camera 4 in the front-rear direction. The mounting surface 11a is formed in a U-shaped bag shape.

  An attachment screw 15 is inserted into an elongated engagement hole 11g formed in the attachment surface 11a and screwed with a nut 16 to fix the camera 4 and the camera bracket 12 to the attachment surface 11a.

  As shown in FIG. 5, the clamping portion 11 e is pressed in the direction of the license plate 2 (in the direction of the arrow F <b> 1) from the upper surface S <b> 1 by tightening the mounting screw 15, and stress due to this pressing is applied to the uneven portion 2 b of the license plate 2. Thus, the license plate 2 can be held.

  Next, a procedure for mounting the mounting bracket 10 on the vehicle 1 will be described.

  First, as shown in FIGS. 2 and 4, the license plate 2 is removed from the bumper 3 by loosening a mounting screw (not shown), and the mounting bracket 11 is removed from either the left or right end of the license plate 2. The concavo-convex portion 2b of the license plate 2 is inserted and clamped by the clamping portions 11e provided on the upper and lower ends. Then, the mounting bracket 11 sandwiching the concave and convex portion 2b of the license plate 2 is slid and adjusted so as to be positioned on the center line C1 of the vehicle width. At this time, if each clamping part 11e of the mounting bracket 11 is expanded and slid outward, the clamping force is reduced or the license plate 2 is not contacted, so that the clamping part 11e can be smoothly slid. Next, the license plate 2 sandwiched between the mounting brackets 11 is fixedly mounted on the bumper 3 using mounting screws (not shown).

  Then, the camera 4 is placed on the camera bracket 12, and the position of the camera 4 is adjusted in the front-rear direction so that the camera 4 falls within the range defined by the road regulations through the engagement hole 11g formed in the mounting surface 11a of the mounting bracket 11.

  After the position adjustment, the mounting screw 15 is inserted into the engaging hole 11g of the mounting surface 11a and screwed with the nut 16 to mount the camera bracket 12 to the mounting surface 11a. By screwing the mounting screw 15 to the mounting surface 11a of the camera bracket 12, the clamping portion 11e is pressed from the upper surface S1 in the direction of the license plate 2 (in the direction of the arrow F1). The portion 2b is energized, and the license plate 2 is held by the holding portion 11e.

  At this time, since the clamping part 11e that clamps the license plate 2 is integrally formed via the connecting part 11c, the mounting surface 11a of the mounting bracket 11 is supported at two points on the upper and lower ends of the license plate 2. Therefore, the camera 4 can be firmly attached and fixed on the parallel line along the license plate 2 without any blur.

  In the first embodiment, the mounting bracket 11 and the camera bracket 12 are separately configured to be engaged with a mounting screw or the like. However, the mounting bracket 11 and the camera bracket 12 are integrally formed regardless of this, The structure may be simplified. Alternatively, the camera 4 may be directly fixed to the mounting bracket 11.

  In the first embodiment, an engagement hole 11g for adjusting the camera 4 in the front-rear direction is formed on the side of the mounting bracket 11 to which the camera bracket 12 is attached. However, the camera bracket 12 is not limited to this. On the side, a hole for adjusting the camera 4 in the front-rear direction may be formed as a long hole.

  In the first embodiment, the mounting surface 11a of the mounting bracket 11 is adjusted to a position that fits in the uneven portion 3a of the bumper 3. However, when the bumper 3 does not have the uneven portion 3a, FIG. As shown in FIG. 4, the holding portion 11e of the mounting bracket 11 may be formed as it is, and integrally formed in a shape in which only the mounting surface 11a is turned over, and mounted so that the mounting surface 11a protrudes in the vehicle front direction. However, adjustment is made so that the tip of the mounting surface 11a (or the tip of the camera 4 when the camera 4 is mounted) is within the range defined by the road regulations as shown in FIG.

  Further, the mounting bracket device 10 for the in-vehicle camera according to the first embodiment can be mounted upside down as shown in FIG. However, when mounting the mounting surface 11a of the mounting bracket device 10 downward, as shown in FIG. 6 (a), the mounting position of the camera 4 is restricted according to road regulations (for example, in the case of a normal passenger car). The vehicle height H1 from the ground surface needs to be set within a range of 9 cm or more.

As described above, the mounting position of the camera 4 is adjusted so that the mounting bracket 11 is slid in a state where the mounting bracket 11 is sandwiched between the concave and convex portions 2b provided at the upper and lower ends of the license plate 2 and positioned on the center line C1 of the vehicle width. In addition, the camera 4 can be moved and adjusted on the mounting bracket 11 in the front-rear direction. Further, when the camera 4 is placed on the mounting bracket 11 by the mounting screw 15, the clamping force of the mounting bracket 11 to the license plate 2 can be urged by the force that the mounting bracket 11 is engaged and distorted by the mounting screw 15. . As a result, the mounting bracket 11 for mounting and fixing the camera 4 can be easily fixed to the upper and lower ends of the license plate 2, and the mounting position of the camera 4 can be moved and adjusted within the road regulation range, and at the same time, the center of the vehicle width It becomes possible to adjust the movement to a position on the line. Moreover, it becomes possible to strengthen the clamping force of the mounting bracket 11 to the license plate 2.

As shown in FIG. 8, the clamping portion 31e is pressed in the direction of the license plate 2 (in the direction of the arrow F31) from the upper surface S31 by tightening the mounting screw 35, and the stress due to this pressing is applied to the uneven portion 2b of the license plate 2. Thus, the license plate 2 can be held.

  Next, a procedure for mounting the mounting bracket 30 to the vehicle 1 will be described.

  First, as shown in FIGS. 7 and 8, the mounting bracket 31 is fitted from either one of the upper and lower ends of the license plate 2, and the uneven portion 2b of the license plate 2 is sandwiched and sandwiched by the sandwiching portion 31e. . Then, the mounting bracket 31 sandwiching the uneven portion 2b of the license plate 2 is slid and adjusted so as to be positioned on the center line of the vehicle width. At this time, if the clamping part 31e of the mounting bracket 31 is expanded and slid outward, the clamping force is reduced or it does not contact the license plate 2, so that the clamping part 31e can be smoothly slid.

  Then, the camera 4 is placed on the camera bracket 32, and the position of the camera 4 is adjusted in the front-rear direction through the engagement hole 31g formed in the attachment surface 31a of the attachment bracket 31 so that the camera 4 falls within the range defined by road regulations.

  After the position adjustment, the attachment screw 35 is inserted into the engagement hole 31g of the attachment surface 31a, and is screwed with the nut 36 to attach the camera bracket 32 to the attachment surface 31a. By screwing the mounting screw 35 to the mounting surface 31a of the camera bracket 32, the clamping portion 31e is pressed from the upper surface S31 in the direction of the license plate 2 (in the direction of the arrow F31). The portion 2b is energized, and the sandwiching portion 31e is sandwiched between the license plates 2. By clamping the license plate 2 to the mounting bracket 31 using the mounting screw 35, the clamping force of the clamping part 31e is strengthened, and the mounting bracket 31 is prevented from being unevenly held in a parallel position along the license plate 2. Can be attached firmly.

  In the second embodiment, the mounting bracket 31 and the camera bracket 32 are separately configured to be engaged with a mounting screw or the like, but the mounting bracket 31 and the camera bracket 32 are integrally formed regardless of this, The structure may be simplified. Alternatively, the camera 4 may be directly fixed to the mounting bracket 31.

  In the second embodiment, the mounting surface 31a of the mounting bracket 31 is adjusted to a position that fits in the uneven portion 3a of the bumper 3. However, if the bumper 3 does not have the uneven portion 3a, the mounting bracket 31 The pinching portion 31e of 31 may be formed as it is, integrally formed in a shape in which only the mounting surface 31a is turned over, and mounted so that the mounting surface 31a protrudes in the vehicle front direction.

  However, adjustment is made so that the tip of the mounting surface 31a (or the tip of the camera 4 when the camera 4 is mounted) is within the range defined by the road regulations as shown in FIG.

  In the second embodiment, an engagement hole 31g for adjusting the camera 4 in the front-rear direction is formed on the side of the mounting bracket 31 to which the camera 4 is attached, but the camera bracket 32 side is not particularly concerned with this. In addition, a hole for adjusting the camera 4 in the front-rear direction may be formed as a long hole.

  In the second embodiment, the mounting bracket 31 and the camera bracket 32 are configured separately so that the mounting screws are engaged at two locations. However, the number of engaging locations is one, without being particular about this. Two or more may be sufficient.

As described above, the mounting position of the camera 4 is slid in a state where the mounting bracket 31 is sandwiched between the uneven portions 2b of the uneven portions 2b provided at the upper and lower ends of the license plate 2 and is on the center line of the vehicle width. The camera 4 can be adjusted so as to be positioned, and the camera 4 can be moved and adjusted on the mounting bracket 31 in the front-rear direction. Further, when the camera 4 is placed on the mounting bracket 31 with the mounting screw 35, the clamping force of the mounting bracket 31 to the license plate 2 can be urged by the force that the mounting bracket 31 is engaged and distorted by the mounting screw 35. . As a result, the mounting bracket 31 for mounting and fixing the camera 4 can be easily fixed to either one of the upper and lower ends of the license plate 2 and the mounting position of the camera 4 can be moved and adjusted within the road regulation range. At the same time, it is possible to adjust the movement to a position on the center line of the vehicle width. In addition, it is possible to enhance the clamping force of the mounting bracket 31 to the license plate 2.

Embodiment 3 of the present invention will be described with reference to the drawings.

  FIG. 9 is a cross-sectional view of a mounting bracket device for a vehicle-mounted camera according to a third embodiment of the present invention. 10A and 10B are explanatory diagrams for explaining the mounting action of the mounting bracket device for the in-vehicle camera according to the third embodiment of the present invention. FIG. 10A is a state diagram before mounting, FIG. 10B is a state diagram in the middle of mounting, and FIG. FIG.

  The mounting bracket device 40 of the in-vehicle camera of the third embodiment adds a protruding piece, a hinge portion, and a bearing portion to the mounting bracket without using the mounting screw 35 with respect to the mounting bracket device 30 of the camera 4 of the second embodiment. The clamping force to the license plate 2 is urged using the elastic force of the mounting bracket.

  As shown in FIGS. 9 and 10, the mounting bracket device 40 of the in-vehicle camera includes a mounting surface 47a for mounting the camera bracket 42, a first mounting bracket 47 having a hinge portion 47d having a protruding piece 47b, and a bearing portion. The camera bracket 42 is engaged with the first mounting bracket 47 by a mounting screw 45. The second mounting bracket 48 includes 48b.

  Since the camera bracket 42 is the same as that of the first embodiment, the description thereof is omitted.

  As shown in FIGS. 9 and 10, the first mounting bracket 47 includes a sandwiching portion 47 e, a mounting surface 47 a, and a protruding piece 47 b, and is integrally formed of an elastic metal material or the like.

  The sandwiching portion 47e is formed, for example, in an uneven shape that is the same shape as the uneven portion 2b of the license plate 2 so as to correspond to the position of the uneven portion 2b of the license plate 2.

  The attachment surface 47a is provided with an engagement hole 47f for inserting an attachment screw 45 for fixing the camera bracket 42. The engagement hole 47f is formed in a long hole shape in order to adjust the position of the camera 4 in the front-rear direction. A hinge portion 47d is formed on the rear end side of the mounting surface 47a, and a protruding piece 47b is integrally formed with the hinge portion 47d.

  The second mounting bracket 48 includes an upper surface portion 48a, a side surface 48d, a bottom surface portion 48c, and a sandwiching portion 48e in which the bottom surface portion 48c is bent in an L shape. It is integrally molded with. The upper surface portion 48 a is formed with a bearing portion 48 b that engages with the hinge portion 47 d of the first mounting bracket 47 at the front end portion. Further, the sandwiching portion 47e is formed in an uneven shape that is the same shape as the uneven portion 2b of the license plate 2, for example, so as to correspond to the position of the uneven portion 2b of the license plate 2. The plate thickness of the upper surface portion 48a and the side surface 48d of the second mounting bracket 48 is formed into a shape thinner than the plate thickness of the bottom surface portion 48c and the sandwiching portion 48e, so that it is easily distorted.

  Then, with the first mounting bracket 47 and the second mounting bracket 48 being connected by the hinge portion 47d and the bearing portion 48b, respectively, the clamping portion 48e of the second mounting bracket 48 is brought into contact with the uneven portion 2b of the license plate 2. The first mounting bracket 47 is rotated in the direction of the license plate 2 so that the clamping portion 47e is urged toward the concavo-convex portion 2b so that the license plate 2 is clamped by the first and second mounting brackets 47 and 48. Yes.

  Next, a procedure for attaching the mounting bracket device 40 to the vehicle will be described with reference to FIG.

  First, as shown in FIG. 10A, the hinge portion 47 d of the first mounting bracket 47 is engaged with the bearing portion 48 b of the second mounting bracket 48 and connected. Then, the position of the first mounting bracket 47 on the license plate 2 is adjusted to be on the center line of the vehicle width in a state where the clamping portion 48e of the second mounting bracket 48 is in contact with the uneven portion 2b of the license plate 2. To do.

  In this state, as shown in FIG. 10, (a), the second mounting bracket 48 is not distorted, the height from the bottom surface portion 48c of the bearing portion 48b is H41, and the tip of the protruding piece 47b is the bottom surface. It is in contact with P41 of the portion 48c. Further, the mounting surface 47a and the clamping portion 47e integrated with the projecting piece 47b are spaced upward from the license plate 2. When the holding portion 47e is rotated in the R41 direction while holding the second mounting bracket 48, the protruding piece 47b is interlocked and rotated in the R41 direction with the hinge portion 47d as a fulcrum. At this time, the tip of the projecting piece 47b slides on the bottom surface portion 48c and moves in the F41 direction, the top surface portion 48a and the side surface 48d are distorted in the R44 direction, and the bearing portion 48d is lifted upward. FIG. 10B shows a state in the middle of the rotation of the sandwiching portion 47e in the R41 direction.

  In the state during the mounting, as shown in FIG. 10B, the upper surface portion 48a and the side surface 48d of the second mounting bracket 48 are distorted in the R44 direction, the bearing portion 48d is lifted upward, and the bottom surface of the bearing portion 48b. The height from the portion 48c is increased from H41 to H42. At this time, the protruding piece 47b is interlocked so that the tip of the protruding piece 47b slides on the bottom surface portion 48c from P41 to P42. If the position in this state is the position of the rotation action point (the rotation action point due to the pressing to the clamping part 47e), the upper surface part 48a and the side face 48d are distorted when the tip of the protruding piece 47b passes the rotation action point. The force in the R44 direction changes to a force in the R45 direction due to a reaction force due to distortion. A component force due to the reaction force in the R45 direction is applied in the F41 direction, the tip of the protruding piece 47b slides on the bottom surface portion 48c and moves in the F41 direction, and the bearing portion 48d is lowered downward.

  At this time, the clamping portion 47e is rotated in the R42 direction in conjunction with the protruding piece 47b. FIG. 10 (c) shows a state after the projecting piece 47b is rotated in the R45 direction and after the license plate 2 is clamped.

  In the state after the mounting, as shown in FIG. 10, (c), the component force due to the distorted reaction force of the upper surface portion 48a and the side surface 48d is the force that slides the bottom surface portion 48c in the F41 direction at the tip of the protruding piece 47b. As a result, the tip of the protruding piece 47b slides from P42 to P43. At this time, the sandwiching portion 47e is interlocked with the protruding piece 47b and rotated in the R42 direction to urge the concavo-convex portion 2b of the license plate 2 from the front side. And the bearing part 48d is lowered | hung below and the height from the bottom face part 48c of the bearing part 48b is low from H42 to H43.

  The height H43 from the bottom surface portion 48c of the bearing portion 48d after attachment is set to be higher than the height H41 before attachment shown in FIG. 10 (a) (H43> H41). In other words, the urging of the sandwiching portion 47e to the concavo-convex portion 2b of the license plate 2 is due to a reaction force due to the difference between the height H43 after attachment and the height H41 before attachment. Therefore, it is possible to arbitrarily set the urging force by arbitrarily changing the difference between the height H43 after attachment and the height H41 before attachment.

  In the third embodiment, the first mounting bracket 47 and the second mounting bracket 48 are attached to one of the upper end side and the lower end side of the license plate 2, but the first embodiment is not limited to this. As shown in FIG. 6, the present invention can also be applied to one in which a sandwiching portion to which a camera provided on the upper end side is attached and a sandwiching portion provided on the lower end side are connected by a connecting plate and integrally formed.

  In the third embodiment, the first mounting bracket 47 and the second mounting bracket 48 are not only used to urge the clamping force to the license plate 2 by using the elasticity of the material formed, but also to the first mounting bracket. An adhesive such as a double-sided tape may be applied to the back side near the concavo-convex portion 47b of 47 to further strengthen the clamping force.

  As described above, the first mounting bracket 47 and the second mounting bracket 48 are connected via the hinge portion 47d and the bearing portion 48b, and the sandwiching portion 47e of the first mounting bracket 47 is rotated in the direction of the license plate 2 to obtain the license plate. 2 is sandwiched between the first mounting bracket 47 and the second mounting bracket 48, and the license plate 2 can be sandwiched between the first mounting bracket 47. In addition, the second mounting bracket 48 is distorted via the protruding piece 47e during rotation, and a reaction force due to this distortion is urged as a force in the direction in which the license plate 2 is sandwiched by the first mounting bracket 47. As a result, the force for clamping the license plate 2 by the first and second mounting brackets 47 and 48 is strengthened, and the license plate 2 is clamped and fixed by the first and second mounting brackets 47 and 48 without using mounting screws or the like. Therefore, it becomes possible to operate more easily.

  In this embodiment, the shape of the sandwiching part is the same as the unevenness of the license plate. However, the shape of the sandwiching part is not limited to the unevenness, and as shown in FIG.
