Description

The present invention relates to an in-vehicle image pickup device mounted on a vehicle and capable of picking up an image of the surroundings.

2. Description of the Related Art Conventionally, there is known an in-vehicle system that uses an image of an object captured by a pair of cameras to calculate a distance to the object by triangulation and thereby recognizes the object. Especially in an in-vehicle environment, there is an application request to detect other vehicles in front of the vehicle, people, obstacles, etc., and deal with them safely in advance, so the distance measurement and recognition of long-distance objects can be reliably realized. There is a need to.

In such an in-vehicle system, from the pixel information included in a pair of images, the pixel position of the feature point common to the mutual images is specified, and the number of pixels where the feature point is deviated in the pair of images (hereinafter, Generally, a dedicated LSI (integrated circuit) that performs a process for obtaining “parallax” is mounted. For this reason, it is ideal that there is no deviation other than parallax between the pair of images, and adjustment is performed with high accuracy so that there is no deviation in optical characteristics or signal characteristics for each camera that captures each of the pair of images. It is necessary to have a structure that can maintain the accuracy. Also, in order to improve the detection performance of vehicles in front, it is necessary to definitely find the common feature points in a pair of images, and for that purpose, the brightness value of each feature point becomes a pair with the reference camera. It is preferable that one camera has the same value.

Since the above-described characteristics are required, it is required that the vehicle-mounted camera can be fixed at a predetermined position in the structure for mounting the vehicle-mounted camera on the vehicle. For example, in the invention disclosed in Japanese Patent Laid-Open No. 2012-166615, a bracket is preliminarily adhered to a windshield of a vehicle and a vehicle-mounted camera is attached to the bracket. The in-vehicle camera is attached and fixed while pressing the spring.

JP 2012-166615 A

Although the vehicle-mounted camera is provided inside the vehicle, it is desirable to fix the vehicle-mounted camera to the window glass of the vehicle so that the outside can be imaged. Considering the in-vehicle camera mounting process in the vehicle assembly process, the process of mounting the in-vehicle camera on the window glass is reached compared to the time required for the window glass to be adhesively fixed to the vehicle body part and the adhesive agent is completely cured. It takes less time to do. Therefore, in order to efficiently perform the vehicle assembly process, it is conceivable to attach the vehicle-mounted camera to the window glass in an unstable state where the adhesion between the window glass and the vehicle body portion is not completely cured.

However, in the structure described in Japanese Unexamined Patent Application Publication No. 2012-166615, the window glass is pushed by the vehicle-mounted camera in a direction perpendicular to the surface when the vehicle-mounted camera is attached. In this case, a large load is applied to the window glass, and the positional relationship between the window glass and the vehicle body portion may be broken in a state where the adhesion between the window glass and the vehicle body portion is not completely cured. As a result, the installation accuracy of the camera is deteriorated.

An object of the present invention is to provide an in-vehicle image pickup device that can be attached to a window glass of a vehicle without deteriorating installation accuracy.

In order to achieve the above-mentioned object, the present invention, in a vehicle-mounted imaging device, an imaging unit that captures an image, a holding unit that has a shielding unit that shields a part of the imaging unit, and a holding unit that holds the imaging unit, And the imaging unit has a supported portion supported by the holding unit, the holding unit has an adhesive surface adhered to the window glass, a receiving unit, and a leaf spring, The receiving portion extends from one end of the receiving portion in a first direction substantially parallel to the bonding surface, and then bends in a U shape in a direction away from the bonding surface, and thereafter, is opposite to the first direction. The receiving portion extends in a second direction to reach the other end of the receiving portion, and the receiving portion has a groove portion that is recessed in a direction substantially parallel to the bonding surface along a direction in which the receiving portion extends, and the imaging portion has the shielding portion. A guide portion that guides the supported portion in the first direction that is a direction closer to, and a support portion that supports the supported portion after being guided by the guide portion. A contact portion disposed on a surface on the other end side of the receiving portion that faces the adhesive surface, the contact portion contacting the supported portion, and a leaf spring fitted in the groove portion and facing the contact portion. An opening formed between the one end and the supported portion, which is an opening toward the guide portion and into which the supported portion enters, is the receiving portion of the end portion of the leaf spring. Is an opening formed by one end of the leaf spring arranged on one end side of the leaf spring and the abutting portion facing the one end of the leaf spring, and the leaf spring is provided from one end of the leaf spring through the groove portion. Extending to the other end of the leaf spring, and the other end of the leaf spring is a surface on the other end side of the receiving portion that faces the bonding surface and a surface on the other end side of the receiving portion. The leaf spring is disposed between the adhesive surface and a surface that does not face the adhesive surface, and one end of the leaf spring biases the supported portion in a direction away from the adhesive surface.

ADVANTAGE OF THE INVENTION According to this invention, the vehicle-mounted imaging device which can be attached to the window glass of a vehicle can be provided, without deteriorating installation precision.

The vehicle-mounted camera 11 includes two camera units 22 capable of capturing images via the lens 21. The camera unit 22 includes an image pickup device (not shown) such as a CCD (Charge Coupled Device) or a CMOS (Complementary Metal Oxide Semiconductor), and as shown in FIG. .. Further, as shown in FIG. 2, the lens hood 33 can prevent light other than the imaging range 16 from entering the camera unit 22.

In addition, although two camera units 22 are provided in the present embodiment, the present invention is not limited to this, and the present invention has an in-vehicle image pickup device having one camera unit and three or more camera units. It is also applicable to an in-vehicle image pickup device.

The vehicle-mounted camera 11 has an unillustrated LSI (integrated circuit), and this LSI uses an image captured by the camera unit 22 to analyze the outside world such as recognition of an object and calculation of a distance to the object. The image captured by the camera unit 22 and the analysis result by the LSI are externally output by an unillustrated external output unit (whether wired or wireless) in the vehicle-mounted camera 11 and used for controlling the vehicle 40.

A shaft portion 17 is provided at each of both ends of the vehicle-mounted camera 11, and a convex portion 23 is provided in front of the center of the vehicle-mounted camera 11. The vehicle-mounted camera 11 is attached to the bracket 13 by the shaft portions 17 and the convex portions 23 on both sides. That is, the vehicle-mounted camera 11 is supported on the bracket 13 by the shaft portions 17 and the convex portions 23 on both sides at three points. By this three-point support, the posture direction of the vehicle-mounted camera 11 is determined, and the imaging range of the camera unit 22 is fixed.

FIG. 4 is a perspective view of the bracket 13 shown in FIGS. 1 and 2, and is a view seen from the upper right side of FIG. 1.

A receiving portion 15 is provided at each of both ends of the bracket 13, and a receiving portion 35 is provided at the rear of the center of the bracket 13. The receiving portion 35 receives the convex portion 23 when the in-vehicle camera 11 is attached, and each of the two receiving portions 15 receives each of the two shaft portions 17 when the in-vehicle camera 11 is attached.

The vehicle-mounted camera 11 is moved along the direction of the surface of the window glass 12 (substantially parallel to the surface of the window glass 12, that is, the bonding surface 32) from diagonally above to diagonally below (the lens 21 is moved to the lens hood). 33, and is attached to the bracket 13. The receiving portion 35 has a concave portion 35 a into which the convex portion 23 fits and a leaf spring 34. The leaf spring 34, which is an elastic body, is deformed by being pushed by the convex portion 23 when the convex portion 23 is fitted in the concave portion 35a, and holds and fixes the convex portion 23 with a force that restores against this deformation.

Next, the structures of the shaft portion 17 and the receiving portion 15 will be described in detail.

FIG. 5 is an enlarged perspective view showing one of the two receiving portions 15 (the receiving portion 15 on the left side in FIG. 4).

FIG. 6 is a perspective view of the receiving portion 15 of FIG. 5 viewed from below.

The receiving portion 15 is provided with a wall portion 15c on the inner side, as can be seen from the receiving portion 15 on the right side in FIG. 4, while the receiving portion 15 on the left side in FIG. 4 (the receiving portion 15 in FIGS. 5 and 6). ), a U-shaped groove 15d is provided on the outside. The bottom of the groove 15d is the wall 15c. A leaf spring 14 having a U-shaped cross section is fitted in the groove 15d in accordance with the U-shaped shape of the groove 15d. The receiving portion 15 has a retaining portion 36, and the leaf spring 14 which is an elastic body fitted in the groove portion 15d is fitted between the wall portion 15c and the retaining portion 36 so as not to come off from the groove portion 15d. ing. A plurality of retaining portions 36 may be provided. By providing a plurality of blades, the effect of preventing the leaf spring 14 from falling off is further improved. The leaf spring 14 may be integrally molded with the receiving portion 15, but in the present embodiment, it is a separate body from the receiving portion 15, and the receiving portion 15 is made of, for example, resin, and the leaf spring 14 is made of, for example, metal. It is a leaf spring.

A guide surface 15a is provided on the upper side of the receiving portion 15, and the guide surface 14a of the leaf spring 14 is located at a position facing the guide surface 15a. An opening 15e is formed between the guide surface 15a and the guide surface 14a.

The guide surface 14a, which is one end of the leaf spring 14, is bent at the bent portion 14b, and the angle of the guide surface 14a is adjusted by this bending. It is guided so that it can easily enter the opening 15e.

The leaf spring 14 has a linear portion 14c from the guide surface 14a via the bent portion 14b, and then has a linear portion 14e forming the other end via the curved portion 14d. The end of the linear portion 14e extends beyond the position of the retaining portion 36, and extends to a position corresponding to the position of the bent portion 14b in the vertical direction of the U shape.

When the shaft portion 17 is made to enter the opening 15e, the U-shaped opening of the leaf spring 14 is widened, and the elastic force of the leaf spring 14 presses the shaft portion 17 against the receiving portion 15. When the shaft portion 17 passes through the opening 15e, the shaft portion 17 reaches the space portion 15f. The space portion 15f is a space formed between the leaf spring 14 and the contact portion 15b. The contact portion 15b is composed of two surfaces that are substantially perpendicular to each other. The shaft portion 17 reaching the space portion 15f is supported at three points by the two surfaces of the abutting portion 15b and the leaf spring 14, and the force of the leaf spring 14 to restore against deformation deforms the shaft portion 17. The shaft portion 17 is held and fixed by being pressed against the contact portion 15b.

In the present embodiment, the abutting portion 15b has two surfaces, that is, a surface having an angle of approximately 45 degrees and a surface having an angle of approximately 135 degrees with the linear portion 14c of the leaf spring 14, but the present invention is not limited to this. The two surfaces may be provided at an angle other than a right angle.

Next, the structure of the leaf spring 34 of the receiving portion 35 shown in FIG. 4 will be described.

FIG. 7 is a perspective view of the receiving portion 35 shown in FIG. 4 seen from the back surface of FIG.

The receiving portion 35 has a retaining portion 37, and the retaining portion 37 presses the leaf spring 34 to prevent the leaf spring 34 from falling off. In FIG. 7, a plurality of retaining portions 37 are provided. By providing a plurality of leaf springs 34, the effect of preventing the leaf springs 34 from falling off is further improved.

FIG. 8 is a schematic side view of the vehicle 40 showing how the vehicle-mounted imaging device 100 shown in FIG. 1 is attached to the vehicle 40.

As a mounting order, the window glass 12 is generally mounted on the vehicle body 41 before the vehicle-mounted camera 11. The joint 43 between the window glass 12 and the vehicle body 41 is generally fixed by an adhesive. Joining and mounting from the window glass 12 to the vehicle-mounted camera 11 are as described above. As shown in FIG. 8, the vehicle-mounted camera 11 is preferably arranged above the window glass 12 so as not to obstruct the driver's visual field.

As described above, the bracket 13 has the lens hood 33 so that light other than the imaging range 16 of the vehicle-mounted camera 11 does not enter the camera unit 22. The positional relationship between the lens hood 33 and the camera section 22 is shown in FIG.

FIG. 9 is a side view showing the lens hood 33 by removing the vicinity of the receiving portion 15 from the side view shown in FIG. 2 so that the lens hood 33 can be seen.

Considering the design, it is preferable that the lens hood 33 and the front end portion 52 of the camera unit 22 can be installed close to each other. When the vehicle-mounted imaging device 100 is viewed from the outside of the vehicle, the parts other than the lens 21 can be covered by the close installation.

(Other)
The bracket 13 has a receiving portion 15 and a leaf spring 14 as a guide portion for determining the mounting direction of the vehicle-mounted camera 11. By providing an opening of the guide portion so that the direction in which the shaft portion 17 moves from the guide portion to the holding position of the shaft portion 17 is as parallel as possible to the window glass 12 (connecting the opening portion 15e and the space portion 15f). By making the line as parallel as possible to the surface of the window glass 12), the direction of the load applied when mounting the vehicle-mounted camera 11 is also parallel to the window glass 12, and the window glass 12 is separated from the vehicle body 41. Such a load becomes small. Thereby, the vehicle-mounted camera 11 can be attached while maintaining the positional relationship between the window glass 12 and the vehicle body 41.

The leaf spring 14 has a mounting angle such that the direction in which the load is applied is the direction away from the window glass 12 as shown in FIG. For example, if the direction in which the shaft portion 17 passes through the guide portion is parallel to the window glass 12, it is preferable that the direction of the load applied to the shaft portion 17 in the space 15f is perpendicular to the surface of the window glass 12. However, the direction of the load applied to the window glass 12 does not have to be completely vertical.

It is preferable that the reference surfaces (the two surfaces of the contact portion 15b) of the bracket 13 are provided symmetrically with respect to the direction of the load applied to the shaft portion 17 in the space 15f. However, it does not have to be completely axisymmetric.

If the mounting direction in which the shaft portion 17 moves from the opening portion 15e to the space portion 15f is set to an angle larger than the angle of the window glass 12 with respect to the ground, the load applied to the window glass 12 can be further reduced. As a result, the shaft portion 17 that has passed through the opening portion 15e is finally moved by the leaf spring 14 in the direction away from the window glass 12, and the reference surfaces of the leaf spring 14 and the bracket 13 (the two contact portions of the abutting portion 15b). Surface) and is clamped between and fixed. As a result, the force is not applied in the direction of separating the window glass 12 from the vehicle body 41 not only when the window glass 12 is attached but also when the shaft portion 17 is fixed in the space 15f, and the positional relationship between the window glass 12 and the vehicle body 41 is maintained. It is possible.

The leaf spring that biases the shaft portion 17 in the space 15f may be a member different from the receiving portion of the bracket 13, but may be the same member, for example, one that forms the receiving portion and the leaf spring with a plastic material. .. Further, the elastic body is not limited to the leaf spring and may be another elastic body.

Since the leaf spring 14 has a U-shaped cross-sectional shape and holds and fixes the shaft portion 17 and the contact portion 15b, one end of the leaf spring 14 is in contact with the shaft portion 17 and the other end is The length is set such that the contact point between the leaf spring 14 and the receiving portion 15 is located on the extension line of the line connecting the contact point between the leaf spring 14 and the shaft portion 17 and the center of the shaft portion 17.

FIG. 10 is an enlarged side view showing the vicinity of the receiving portion of the bracket of the vehicle-mounted image pickup apparatus according to the second embodiment of the present invention.

The present embodiment is the same as the first embodiment except for the points shown in FIG. 10 and will not be described.

In FIG. 10, a leaf spring 114 is provided instead of the leaf spring 14 of the first embodiment. A guide surface 15a is provided on the upper side of the receiving portion 15, and the guide surface 114a of the leaf spring 114 is located at a position facing the guide surface 15a.

The leaf spring 14 has a straight portion 114c from the guide surface 114a, which is one end, through a bent portion 114b, and then has a straight portion 114e that forms the other end through a curved portion 114d. The end of the straight portion 114e extends to a position substantially the same as the position of the retaining portion 36.

That is, in this embodiment, one end of the leaf spring 114 contacts the shaft portion 17, and the other end has a shape shorter than an extension line connecting the contact point between the leaf spring 114 and the shaft portion 17 and the center of the shaft portion 17. There is. The present invention may use the leaf spring 114 having such a shape.

FIG. 11 is an enlarged side view showing the vicinity of the receiving portion of the bracket of the vehicle-mounted image pickup apparatus according to the third embodiment of the present invention.

This example is the same as Example 1 and Example 2 except for the points shown in FIG. 11 and will not be described.

In FIG. 11, the same leaf spring 114 as that of the second embodiment is provided instead of the leaf spring 14 of the first embodiment. That is, in this embodiment, one end of the leaf spring 114 contacts the shaft portion 17, and the other end has a shape shorter than an extension line connecting the contact point between the leaf spring 114 and the shaft portion 17 and the center of the shaft portion 17. There is. In this case, a moment may be generated due to the positional relationship between the contact positions of one end and the other end of the leaf spring 114. In the present embodiment, corresponding to this, the contact portion 115b is provided instead of the contact portion 15b. In the contact portion 115b, the angles of the two surfaces contacting the shaft portion 17 are different from those of the contact portion 15b. By adjusting the angles of the two surfaces contacting the shaft portion 17, The force can be evenly applied to the two surfaces that abut.

In the example of FIG. 11, the contact portion 115b is composed of two surfaces that are substantially perpendicular, and the intersection of these two surfaces should be on the line connecting the center of the shaft portion 17 and the end of the straight portion 114e. ing. The angle of the surface may be determined so that there is no loss depending on how the force is actually applied.

It should be noted that the present invention is not limited to the above-described embodiments, but includes various modifications. For example, the above-described embodiments have been described in detail for the purpose of explaining the present invention in an easy-to-understand manner, and are not necessarily limited to those having all the configurations described.

Further, a part of the configuration of a certain embodiment can be replaced with the configuration of another embodiment, and the configuration of another embodiment can be added to the configuration of a certain embodiment.

Further, with respect to a part of the configuration of each embodiment, other configurations can be added/deleted/replaced.

Further, the present invention includes any combination of the elements of the individual embodiments described above.

Further, although the present invention is applied to a stereo camera, it may be applied to a monocular image processing camera having one camera unit.
