Description

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

Conventionally, an in-vehicle system is known in which an image of an object captured by a pair of cameras is used to calculate the distance to the object by triangulation, and the object is recognized by the calculation. Especially in an in-vehicle environment, there are application requirements such as detecting other vehicles, people, obstacles, etc. in front and taking safe measures in advance, so distance measurement and recognition of long-distance objects are reliably realized. There is a need to.

In such an in-vehicle system, the pixel positions of feature points common to each other are specified from the pixel information contained in the pair of images, and the number of pixels in which the feature points are deviated in the pair of images (hereinafter, It is generally equipped with a dedicated LSI (integrated circuit) that performs processing to obtain (referred to as "parallax"). For this reason, it is ideal that there is no deviation other than parallax between the pair of images, and adjustments are made with high precision so that there is no deviation in optical characteristics or signal characteristics for each camera that captures each of the pair of images. A structure that can maintain the accuracy is required. In addition, in order to improve the detection performance of vehicles in front, it is necessary to definitely find the common feature points in the pair of images, and for that purpose, the brightness value of each feature point is paired with the reference camera. It is preferable that the values are the same for one camera.

Since the above-mentioned characteristics are required, in the structure in which the in-vehicle camera is attached to the vehicle, it is required that the in-vehicle camera can be fixed at a predetermined position. For example, in the invention described in Japanese Patent Application Laid-Open No. 2012-166615, in a structure in which a bracket is attached to the windshield of a vehicle in advance and an in-vehicle camera is attached to the bracket, a plate that urges the windshield in a direction perpendicular to the surface of the windshield. The in-vehicle camera is attached and fixed while pressing the spring.

Japanese Unexamined Patent Publication No. 2012-166615

It is desirable to fix the in-vehicle camera to the window glass of the vehicle so that the outside can be imaged while being provided inside the vehicle. Considering the process of attaching the in-vehicle camera in the vehicle assembly process, the process of attaching the in-vehicle camera to the window glass is reached compared to the time required for the window glass to be adhered and fixed to the vehicle body and the adhesive is completely cured. The time it takes to do this is shorter. Therefore, in order to efficiently complete the vehicle assembly process, it is conceivable to attach the in-vehicle camera to the window glass in an unstable state in which the adhesion between the window glass and the vehicle body portion is not completely cured.

However, in the structure described in JP-A-2012-166615 described above, the window glass is pushed by the vehicle-mounted camera in a direction perpendicular to the surface of the vehicle-mounted camera when the vehicle-mounted camera is attached. In this case, a large load is applied to the window glass, and if the adhesion between the window glass and the vehicle body portion is not completely cured, the mutual positional relationship may be broken, and as a result, the installation accuracy of the camera is deteriorated.

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

In order to achieve the above object, the present invention includes an in-vehicle camera and a bracket for fixing the position of the in-vehicle camera in the in-vehicle camera device, and the in-vehicle camera is attached to the bracket. A passage for being inserted and fixed along the adhesive surface is formed, the passage is formed by a part of the bracket and an elastic body, and the elastic body is a supported portion of the in-vehicle camera and the said. It is characterized in that a bracket is sandwiched and the in-vehicle camera is held by the bracket.

According to the present invention, it is possible to provide an in-vehicle camera device that can be attached to a window glass of a vehicle without deteriorating the installation accuracy.

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 as viewed from below.

The receiving portion 15 is provided with a wall portion 15c inside so that the receiving portion 15 on the right side of FIG. 4 can be seen, while the receiving portion 15 on the left side of FIG. ) Is provided on the outside with a U-shaped groove portion 15d. The bottom of the groove portion 15d is the wall portion 15c. A leaf spring 14 having a U-shaped cross section is fitted in the groove portion 15d to match the U-shaped shape of the groove portion 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 the leaf springs 14, the effect of preventing the leaf springs 14 from falling off is further improved. The leaf spring 14 can be integrally molded with the receiving portion 15, but in this embodiment, the leaf spring 14 is a separate body from the receiving portion 15, the receiving portion 15 is formed of, for example, a resin, and the leaf spring 14 is, for example, a 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, and the shaft portion 17 is formed by the angle of the guide surface 14a and the angle of the guide surface 15a. It guides the opening 15e so that it can easily enter.

The leaf spring 14 has a straight portion 14c from the guide surface 14a via the bent portion 14b, and then has a straight portion 14e forming the other end via the curved portion 14d. The end of the straight 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 attempted to enter the opening 15e, the U-shaped opening of the leaf spring 14 is expanded, 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 right angles. The shaft portion 17 that has reached the space portion 15f is supported at three points by the two surfaces of the contact portion 15b and the leaf spring 14, and the force that the leaf spring 14 restores against the deformation is applied to the shaft portion 17.

In FIG. 7, a plurality of retaining portions 37 are provided. By providing a plurality of the 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 a state in which the in-vehicle imaging device 100 shown in FIG. 1 is attached to the vehicle 40.

Generally, the window glass 12 is attached to the vehicle body 41 before the in-vehicle camera 11. The joint portion 43 between the window glass 12 and the vehicle body 41 is generally fixed by an adhesive. The joining and mounting from the window glass 12 to the in-vehicle 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 field of view.

As described above, the bracket 13 has a 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. FIG. 9 shows the positional relationship between the lens hood 33 and the camera unit 22.

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.

Considering the design, it is preferable that the lens hood 33 and the tip portion 52 of the camera portion 22 can be installed close to each other. By installing them in close proximity to each other, when the vehicle-mounted image pickup device 100 is viewed from the outside of the vehicle, a portion other than the lens 21 can be covered.

(Other)
The bracket 13 has a receiving portion 15 and a leaf spring 14 as guide portions 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 wire as parallel as possible to the surface of the window glass 12), the direction of the load applied when the in-vehicle camera 11 is attached is also parallel to the window glass 12, and the window glass 12 is separated from the vehicle body 41. The applied load becomes smaller. As a result, the in-vehicle 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, assuming that the direction in which the shaft portion 17 passes through the guide portion is parallel to the window glass 12, the direction of the load applied to the shaft portion 17 in the space portion 15f is preferably 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 in a completely vertical relationship.

The reference surfaces of the bracket 13 (two surfaces of the contact portion 15b) are preferably provided axially symmetrical with respect to the direction of the load applied to the shaft portion 17 in the space portion 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 15e finally moves in the direction away from the window glass 12 by the leaf spring 14, and the two reference surfaces of the leaf spring 14 and the bracket 13 (the contact portion 15b). It is sandwiched between the surface) and fixed. As a result, no force is applied in the direction in which the window glass 12 is separated 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 portion 15f, and the positional relationship between the window glass 12 and the vehicle body 41 is maintained. It is possible.

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

In order to hold and fix the shaft portion 17 and the contact portion 15b in a U-shaped cross-sectional shape, one end of the leaf spring 14 is in contact with the shaft portion 17 and the other end is in contact with the shaft portion 17. The length is such that the contact point between the leaf spring 14 and the receiving portion 15 is 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.

In this embodiment, the same as in the first embodiment except for the points described with reference to FIG. 10, and the description thereof will be omitted.

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 at one end via the bent portion 114b, and then has a straight portion 114e forming the other end via the curved portion 114d. The end of the straight portion 114e extends to substantially the same position as the position of the retaining portion 36.

That is, in this embodiment, one end of the leaf spring 114 is in contact with the shaft portion 17, and the other end is formed to have a shape shorter than the 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 the present invention, a leaf spring 114 having such a shape may be used.

In this embodiment, the same as in the first and second embodiments except for the points described with reference to FIG. 11, and the description thereof will be omitted.

In FIG. 11, instead of the leaf spring 14 of the first embodiment, the same leaf spring 114 as that of the second embodiment is provided. That is, in this embodiment, one end of the leaf spring 114 is in contact with the shaft portion 17, and the other end is formed to have a shape shorter than the 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 depending on the positional relationship between the contact positions of one end and the other end of the leaf spring 114. Corresponding to this, in this embodiment, the contact portion 115b is provided instead of the contact portion 15b. In the abutting portion 115b, the angles of the two surfaces that abut the shaft portion 17 are different from those of the abutting portion 15b, and by adjusting the angles of the two surfaces that abut the shaft portion 17, the angle from the shaft portion 17 can be adjusted. The force can be applied evenly to the two surfaces that come into contact with each other.

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

The present invention is not limited to the above-mentioned examples, and includes various modifications. For example, the above-described embodiment has been described in detail in order to explain the present invention in an easy-to-understand manner, and is not necessarily limited to the one including all the described configurations.
