Description

  The present invention relates to an attachment device for attaching a device to a target object.

  Conventionally, an on-vehicle camera is fixed to a vehicle using a bracket attached to the vehicle. For example, when a camera for photographing the rear of a vehicle is installed in a vehicle via a bracket, it is required that the mounting angle in the vertical direction be accurately attached.

If it comprises as this Embodiment, it can avoid that the 2nd member 20 becomes large more than necessary.

  FIG. 7 is a schematic cross-sectional view showing a state in which the first member 10 and the second member 20 are connected. As shown in FIGS. 2 and 7, the first member 10 and the second member 20 are connected by the pair of second wall portions 21a and 21b being disposed between the pair of first wall portions 11a and 11b. Be done. The first member 10 and the second member 20 are fixed by the screw 30 by overlapping the first screw hole 111 and the second screw hole 211. In detail, the first screw hole 111 and the second screw hole 211 are overlapped so that the centers of the holes coincide with each other. The shank 30a of the screw 30 is inserted into the first screw hole 111 and the second screw hole 211 from the outside of the first wall portions 11a and 11b. In the fixed state in which the screw 30 is tightened, the first wall portions 11a and 11b and the second wall portions 21a and 21b contact each other on both the left and right sides and overlap each other.

  In the present embodiment, on the right side, the first wall portion 11 a provided with the first through hole 112 and the second wall portion 21 a provided with the second through hole 212 overlap. Then, on the side (right side) where the first through hole 112 and the second through hole 212 are provided, the shaft portion 30 a of the screw 30 is passed through the hole 40 c of the annular member 40, and the annular member 40 is screwed to the first wall portion It is pressed to 11a. When the first screw hole 111 and the second screw hole 211 are overlapped and fixed by the screw 30, the claw portion 40 b of the annular member 40 is combined with any one of the plurality of first through holes 112 a to 112 h. , And one of the plurality of second through holes 212a to 212g. In the example shown in FIGS. 2 and 7, the claw portion 40b is inserted into the first through hole 112d and the second through hole 212d.

  In a state where the first member 10 and the second member 20 are fixed by the screw 30, the central axis of the screw 30, the center of the hole 40a of the annular member 40, the center of the first screw hole 111, and the second screw It substantially coincides with the center of the hole 211. Here, the term circumferential direction is used with reference to the central axis of the screw 30. The circumferential width W1 (see FIG. 3) of the claw portion 40b is preferably equal to or slightly smaller than the circumferential width W2 (see FIG. 3) of the first through hole 112 and the second through hole 212. Thereby, in the circumferential direction, a clearance does not occur or hardly occurs between the claws 40 b and the first through holes 112 and between the claws 40 b and the second through holes 212.

  According to the present embodiment, in a state where first member 10 and second member 20 are attached via screw 30, relative rotation between first wall portion 11a and second wall portion 21a superimposed on each other Can be blocked by the claws 40b. For this reason, even when a human hand touches the camera 2, for example, it is possible to make it difficult to move the mounting position of the camera 2. Further, in the present embodiment, since the first screw holes 111 and the second screw holes 211 are provided on the left and right sides and the fixing by the screws 30 is performed, the mounting position of the camera 2 can be made more difficult to move.

  Further, according to the present embodiment, before tightening the screw 30, the annular member 40 is passed through the screw 30, the claw portion 40b is inserted into the first through hole 112 and the second through hole 212, and then the screw 30 is tightened. For example, the first member 10 and the second member 20 can be fixed. For this reason, the attachment work of the camera 2 is easy, and the workability can be improved. Further, according to the present embodiment, the camera 2 is selected depending on how to select the through holes for inserting the claws 40 b from the plurality of first through holes 112 a to 112 h and the plurality of second through holes 212 a to 212 g. The mounting angle of can be changed variously. For this reason, the adjustment of the mounting angle of the camera 2 can be easily and appropriately performed without measuring the angle or using a jig, and the workability of the mounting operation of the camera 2 can be improved.

  In the present embodiment, the first member 10 and the second member 20 are connected by arranging the pair of second wall portions 21a and 21b between the pair of first wall portions 11a and 11b. It was composition. This is an example, and the first member 10 and the second member 20 are connected as a pair of first wall portions 11a and 11b are disposed between the pair of second wall portions 21a and 21b. It is also good. In this case, the inner surface of the first screw hole 111 may be threaded, and the inner surface of the second screw hole 211 may not be threaded.

  Moreover, although it was set as the structure which the 1st through-hole 112 and the 2nd through-hole 212 are provided only in the wall parts 11a and 21a of the right side in this Embodiment, this is only an illustration. For example, the first through holes 112 and the second through holes 212 may be provided only in the left wall portions 11 b and 21 b. Further, the first through holes 112 and the second through holes 212 may be provided in both the right side wall portions 11a and 21a and the left side wall portions 11b and 21b. In this case, the number of annular members 40 is not one but two. Fixing by the claws 40b on both the left and right sides makes it possible to make the mounting position of the camera 2 less likely to move.

  By the way, in the configuration in which the camera 2 is covered with the garnish 103 of the rear door 101 as in the present embodiment, it is expected that the force applied to the camera 2 by the human hand is almost the force in the direction of lifting the camera 2 Be done. That is, it is expected that a force in the direction to loosen the screw 30 is applied to the right side of the mounting device 1 and a force in the direction to tighten the screw 30 is applied to the left side. Taking this point into consideration, in the present embodiment, the first through hole 112 and the second through hole 212 are provided only in the direction in which the screw 30 may be loosened, and the rotation is prevented by the claw portion 40 b. There is. Thereby, since the operation | work which arrange | positions the annular member 40 is only one of right and left, the workability of the attachment operation | work of the camera 2 can be improved.

<3. Adjustment of camera mounting angle in mounting device>
FIGS. 8, 9 and 10 are diagrams for explaining the adjustment of the attachment angle of the camera 2 in the attachment device 1. FIG. 8 to 10 are side views. In FIGS. 8, 9 and 10, the mounting angles of the camera 2 are different from each other. 8 to 10, the first member 10 is indicated by a thick broken line so that the relationship between the first member 10 and the second member 20 can be easily understood.

  FIG. 8 shows the case where the mounting angle of the camera 2 is 0 °. The state shown in FIG. 8 is obtained by inserting the claw portion 40 b into the first through hole 112 d and the second through hole 212 d and tightening the screw 30. In the present specification, the mounting position of the camera 2 shown in FIG. 8 is a reference position, and the optical axis direction of the camera 2 at the reference position is 0 °. Further, in the present specification, when the camera 2 is tilted upward from the reference position shown in FIG.

  FIG. 9 shows the case where the mounting angle of the camera 2 is −5 °. The state shown in FIG. 9 is obtained by inserting the claw portion 40 b into the first through hole 112 c and the second through hole 212 c and tightening the screw 30. If only the position of the first through hole 112 where the claw portion 40b is inserted is changed from the first through hole 112d to the first through hole 112c from the reference position shown in FIG. 8, the optical axis OA of the camera 2 is 35 ° = First angle α) facing upward. On the other hand, if only the position of the second through hole 212 where the claw portion 40b is inserted is changed from the second through hole 212d to the second through hole 212c from the reference position shown in FIG. Facing downward (= second angle β). Since the state shown in FIG. 9 is a combination of these two, the orientation of the optical axis OA of the camera is −5 ° (= 35 ° + (− 40 °)).

  FIG. 10 shows the case where the mounting angle of the camera 2 is −10 °. The state shown in FIG. 10 is obtained by inserting the claw portion 40 b into the first through hole 112 b and the second through hole 212 b and tightening the screw 30. If only the position of the first through hole 112 where the claw portion 40b is inserted is changed from the first through hole 112d to the first through hole 112b from the reference position shown in FIG. 8, the optical axis OA of the camera 2 is 70 ° ( = First angle α x 2) facing upward. On the other hand, if only the position of the second through hole 212 into which the claw portion 40b is inserted is changed from the second through hole 212d to the second through hole 212b from the reference position shown in FIG. Turn downward (° = second angle β × 2). Since the state shown in FIG. 10 is a combination of these two, the orientation of the optical axis OA of the camera is −10 ° (= 70 ° + (-80 °)).

  In the above, it has been described that the states shown in FIGS. 9 and 10 can be obtained based on the state shown in FIG. However, this is for convenience of explanation, and when obtaining the states shown in FIGS. 9 and 10, it is not necessary to first obtain the state disposed at the reference position shown in FIG. The combination of the first through hole 112 and the second through hole 212 into which the claw portion 40b is inserted is determined so that the target mounting angle is obtained, and the insertion of the claw portion 40b and the mounting of the screw 30 are performed accordingly. Just do it. It is preferable to create a table showing the relationship between the combination of the first through hole 112 and the second through hole 212 and the mounting angle of the camera 2 obtained thereby. In addition, in order to immediately grasp which through hole in the mounting device the through hole shown in the table points, it is possible to mark the number, symbol, etc., which becomes the name of each through hole, around each through hole 112, 212 It is preferable to keep it. Thereby, the workability of the adjustment operation of the attachment angle of the camera 2 can be improved.

  Moreover, although only the case where the attachment angle of the camera 2 becomes negative was shown above, this is only an illustration. For example, when the claw portion 40b is inserted into the first through hole 112e and the second through hole 212e, the mounting angle of the camera 2 is 5 °. The optical axis OA of the camera 2 that mirrors the rear of the vehicle 100 is adjusted, for example, to be inclined 45 ° obliquely downward with respect to the horizontal direction. For this reason, when the attachment surface 101a (see FIG. 4) to which the first member 10 is attached is a surface parallel to the vertical direction, the attachment angle of the camera 2 only needs to be adjusted in the negative direction. . However, the mounting surface 101a may be a surface inclined with respect to the vertical direction. In the case where the mounting surface 101a is a surface inclined with respect to the vertical direction, the mounting angle of the camera 2 sometimes needs to be adjusted in the positive direction. To this end, in the present embodiment, the mounting angle of the camera 2 can be adjusted in the positive direction.

  In the present embodiment, the difference (= 5 °) between the first angle α (= 35 °) and the second angle β (= 40 °) is the attachment angle of the device (camera) 2 to the target object (vehicle) 100. Is equal to the smallest unit that can be changed. In this configuration, it is convenient because the minimum unit of desired angular adjustment can be obtained by determining the first angle α and the second angle β. In addition, since the minimum unit of angle adjustment is a number obtained easily from the first angle α and the second angle β, it is possible for an operator who adjusts the mounting angle to be less likely to cause confusion.

  In the present embodiment, the first angle α (= 35 °) and the second angle β (= 40 °) have a relationship of a non-integer multiple. For this purpose, in addition to the first angle α and the second angle β, it is possible to adjust the mounting angle of the camera 2 at an angle smaller than them. That is, in the present embodiment, it is possible to finely adjust the mounting angle of the camera 2. Further, in the present embodiment, the first angle α of the first member 10 and the second angle β of the second member 20 can be respectively made larger than the minimum unit of angle adjustment. For this reason, the circumferential width W2 (see FIG. 3) of the first through holes 112 and the second through holes 212 and the circumferential width W1 of the claws 40b inserted into these can be increased. The strength for fixing the first member 10 and the second member 20 can be increased. That is, in the present embodiment, the mounting angle of the camera 2 can be finely adjusted while stably fixing the camera 2 to the vehicle 100.
