Description

The present invention relates to an in-vehicle device having a plurality of cameras.

Recently, in-vehicle devices having a first camera for photographing the outside of a vehicle and a second camera capable of photographing a place different from the first camera, for example, the inside of the vehicle, are known. In such an in-vehicle device, for example, a drive recorder, the first camera is mounted so as to face the outside of the vehicle, and the second camera is mounted so as to face the inside of the vehicle. In a commercial vehicle, the second camera is mounted as a security camera for the inside of the vehicle. In a general vehicle, the second camera can function as a camera for photographing the inside of the vehicle while driving.

On the other hand, the mounting position of the drive recorder is regulated by the safety standards of road transport vehicles. For example, when mounting on the windshield of a vehicle, the drive recorder must be mounted within 20% in the vertical direction from the upper end of the windshield. .. Therefore, when the relative positions of the first camera and the second camera are fixed, it may not be possible to take a picture of an arbitrary place by the second camera depending on the mounting position.

To this end, a drive recorder capable of rotating a second camera to change the shooting direction is disclosed (see, for example, Patent Document 1).

Japanese Unexamined Patent Publication No. 2013-12557

However, in the drive recorder described in Patent Document 1, since the second camera is rotated by one rotation mechanism to change the shooting direction, the second camera cannot be directed in any direction depending on the mounting position. , It may not be possible to shoot anywhere.

Therefore, an object of the present invention is to provide an in-vehicle device capable of photographing an arbitrary place with each of a plurality of cameras.

(1) A first camera and a second camera whose shooting direction can be changed are provided, and the second camera can change the shooting direction to any direction, directly and / or indirectly. It is characterized in that it is configured to be rotatable relative to the first camera in at least two non-parallel directions.

According to this, even when the in-vehicle device is attached to the mounting location of the vehicle based on the shooting direction of the first camera, the second camera can be pointed in any direction to shoot at any place. .. That is, each of the first camera and the second camera can shoot an arbitrary place.

As for the relative rotation of the second camera with respect to the first camera in at least non-parallel directions in two directions, which of the second cameras is compared with the first camera when the in-vehicle device is mounted at the mounting location of the vehicle. It is preferable to configure it so that it can rotate relatively in the direction. For example, it is preferable to provide a rotation mechanism that can rotate relative to the first camera in any direction. By configuring the camera so as to be relatively rotatable in any direction, the shooting direction of the second camera can be changed in more detail to any direction toward an arbitrary place.

Further, it is more preferable to configure the second camera to be rotatable in the horizontal direction and the vertical direction with respect to the first camera when the in-vehicle device is mounted at the mounting location of the vehicle. For example, two rotations that can rotate the second camera with respect to the first camera: left-handed rotation and / or right-handed rotation in the horizontal direction, and upward rotation and / or downward rotation in the vertical direction. It is advisable to provide a mechanism. In this case, the second camera may be configured to rotate directly or indirectly. By configuring the second camera in this way, it is possible to change the shooting direction of the second camera from at least two non-parallel directions with a simple configuration.

The two non-parallel directions referred to here may be two directions in which the rotation directions of the second camera intersect at least one of them. As the two directions intersecting at any one of them, the two directions may be configured so as to intersect at an acute angle (for example, the second rotation direction with respect to the first rotation direction is within 30 degrees), or orthogonally (for example, 90 degrees). ), It is even better to configure the two directions.

As a configuration in which the second camera is rotated relative to the first camera in two directions that are not indirectly parallel to the first camera, for example, a case supporting the second camera is provided with respect to the first camera. It is preferable to have a configuration that can rotate in two directions that are not parallel. Further, as a configuration in which the second camera is rotated relative to the first camera in two directions that are not directly and indirectly parallel to each other, a case in which the second camera is rotatably supported is provided as a second camera. It is preferable to configure the camera so that it can rotate with respect to the first camera in a direction different from the rotation direction of.

It is preferable that the first camera when the in-vehicle device is attached to the attachment location of the vehicle is directly or indirectly fixed to the vehicle. For example, it may be configured to be fixed to the vehicle via the mounting bracket, or the case may be configured to be fixed to the vehicle via the mounting bracket while being fixed to the case. Further, it is more preferable that the first camera is fixed even when the second camera is rotated.

Further, the first camera and the second camera may be configured such that the first camera is directed to the outside of the vehicle and the second camera is directed to the inside of the vehicle, and the first camera is directed to the inside of the vehicle and the second camera is directed to the inside of the vehicle. The camera may be configured to face the outside of the vehicle. In particular, it is preferable to configure the first camera to face the outside of the vehicle and the second camera to face the inside of the vehicle.

Further, the in-vehicle device may be a navigation device with a plurality of cameras, and more preferably a navigation device with a drive recorder function or a drive recorder. By using it in a navigation device, for example, images (still images or moving images) taken by the first camera and the second camera can be stored in association with map information. Further, by using it as a drive recorder, for example, the second camera can be made to function as a security camera or a camera for photographing the inside of a vehicle while driving.

Further, for example, it is preferable to change the shooting direction of the second camera so that the driver's blind spots outside the vehicle and inside the vehicle can be photographed. In this case, the in-vehicle device may have a monitor capable of displaying an image. The monitor may be possessed by an in-vehicle device, or may be configured so that a monitor of another device (for example, a navigation device or a liquid crystal monitor of a smartphone) can be used. By doing so, the driver can check the blind spot by looking at the monitor. When used in this way, it is more preferable to use a second camera with an angle of view suitable for viewing the blind spot. For example, it is preferable to use a camera with an angle of view such that both sides in the width direction are not curved. Since both sides of the captured image in the width direction are not curved, it becomes easier to grasp a sense of distance and to confirm a blind spot. In particular, it is preferable that the second camera is a camera having an angle of view that does not bend on both sides in the width direction, and the first camera is a wide-angle camera that bends on both sides in the width direction.

(2) At least one of the relative rotations in the two non-parallel directions is configured so that the second camera can be rotated to a position where the first camera can shoot a place where shooting is not possible. It is characterized by.

According to this, after rotating the second camera to a position where it is possible to shoot a place where the first camera cannot shoot, a second camera is further rotated in a direction different from the direction in which the camera has been rotated (for example, an intersecting direction). By rotating the camera, it is possible to further change the shooting direction by the second camera in a place where the first camera cannot shoot.

The place where the first camera cannot shoot is, for example, a place outside the angle of view of the first camera, and even more preferably a place rotated 180 degrees from the shooting direction of the first camera. Further, in order to take a picture of a place where the first camera cannot take a picture with the second camera, the second camera is directly set so that the place where the first camera cannot take a picture is within the angle of view of the second camera. Alternatively, it may be configured to be rotatable indirectly, and it is more preferable to configure the second camera to be rotatable 180 degrees or more directly or indirectly with respect to the first camera.

(3) An image in which an image taken by the second camera is usually visually recognized when the second camera is rotated by a predetermined angle or more directly and / or indirectly with respect to the first camera. It is characterized in that the photographed image photographed by the second camera is provided with a control means for rotating the photographed image by 180 degrees in the normal direction of the photographed image.

According to this, even when the second camera is rotated, the captured image taken by the second camera can be an image in a direction that is normally visually recognized. For example, even when the in-vehicle device is attached to the mounting location of the vehicle based on the shooting direction of the first camera and then the second camera is rotated 90 or more in the vertical direction with respect to the first camera, the second camera is used. The image taken by the camera is not an image rotated 180 degrees around the normal line of the photographed image with respect to the user's visual recognition (for example, an image inverted upside down), but an image in a direction that is normally visually recognized. Can be done.

The predetermined angle may be 90 degrees or more in the vertical direction, and more preferably 180 degrees in the vertical direction with respect to the first camera.

As an image that is normally visually recognized, when a display device capable of displaying a captured image is installed in a normal state and the captured image is displayed on the display device, the vertical direction of the image displayed on the display device is the vertical direction of the user. It is preferable to use an image that is not recognized as an inverted image with respect to the visual recognition of.

(4) The first camera is characterized in that the horizontal angle of view when mounted on a vehicle is larger than the horizontal angle of view of the second camera.

According to this, when the first camera is attached to the vehicle mounting location with the first camera facing the outside of the vehicle in order to photograph the outside of the vehicle with the first camera, the angle is wider in the horizontal direction than when the second camera is used to photograph the outside of the vehicle. You can take a picture. As a configuration in which the horizontal angle of view of the first camera is larger than the horizontal angle of view of the second camera, it is preferable to use a lens having a wider angle than that of the second camera.

(5) The first camera is characterized in that the vertical angle of view when mounted on a vehicle is smaller than the vertical angle of view of the second camera.

According to this, when the first camera is attached to the mounting location of the vehicle with the first camera facing the outside of the vehicle in order to photograph the outside of the vehicle with the first camera, the incident of external light is more than that of the outside of the vehicle with the second camera. It can be reduced. As a configuration in which the vertical angle of view of the first camera is smaller than the vertical angle of view of the second camera, it is preferable to use a lens having a narrower vertical angle of view than the second camera.

(6) The first main body having the first camera and the second camera are rotatably supported by the second camera and rotated relative to the first main body. It is characterized by including a second main body portion that is configured so as to be possible.

According to this, even when the first main body is attached to the vehicle mounting position based on the shooting direction of the first camera, the second main body and the second camera are attached to the first main body. By rotating the camera, the second camera can be pointed in any direction and the second camera can take a picture of an arbitrary place.

The second camera may be configured to be rotatably supported by the second main body in any direction including the rotation direction of the second main body with respect to the first main body, and the second main body may be supported by the second main body. It is more preferable that the configuration is supported by the second main body so as to be rotatable in a direction different from the rotation direction with respect to the first main body. As a configuration in which the second main body is rotatably supported by the second camera in any direction, a rotation center is set in the second camera, and the second main body is centered on this rotation center. The second camera may be rotatably supported. For example, it is preferable that the ball joint is integrally attached to the second camera, and the ball joint is rotatably supported by the second main body portion around the center of rotation of the ball joint. Further, as a configuration in which the second camera is rotatably supported by the second main body portion, a rotation axis is set in the second camera, and the second camera is placed in the second main body portion around the rotation axis. It is good to support it rotatably.

The second main body portion refers to a place deviating from the angle of view of the first camera in the rotation direction of the second main body portion with respect to the first main body portion at least until the rotation position at which the second camera can take a picture. It is preferable to have a configuration in which the connections are relatively rotatable. For example, the second main body portion may be configured to be rotatable 180 degrees or more with respect to the first main body portion, and may be configured to be rotatable at least 180 degrees. Since the second main body portion is configured to be rotatable by 180 degrees or more with the first main body portion, the first main body portion in the rotation direction of the second main body portion can be viewed from a portion that overlaps the angle of view range of the first camera. You can shoot up to a place outside the angle of view of the camera. Further, since it is configured to be rotatable 180 degrees, at least a place deviating from the angle of view of the first camera in the rotation direction of the second main body can be photographed by the second camera.

The first camera may be rotatably fixed to the first main body (hereinafter referred to as "semi-fixed"), and even more preferably provided integrally with the first main body. By semi-fixing the first camera to the first main body, for example, the orientation of the first camera can be changed even after the first main body is attached to the mounting position of the vehicle. Further, by providing the first camera integrally with the first main body portion, the in-vehicle device can be made a simple configuration.

The semi-fixed state is preferably a state in which the posture is maintained without rotating when a rotational torque of more than a predetermined value is applied, and when a rotational torque of less than a predetermined value is applied. The rotational torque exceeding a predetermined value may be, for example, a rotational torque that acts when the user picks up and rotates the first camera. In other words, the rotational torque exceeding a predetermined value may be a rotational torque that directly or indirectly acts on the first camera at the will of the user. For example, the power of a motor or the like driven by the user's operation, the user's hand, or the like. It is preferable to use a rotational torque that acts as a result. The rotation torque less than the predetermined value may be a rotation torque or the like that acts on the first camera due to vibration or the like of the running vehicle after the in-vehicle device is attached to the mounting location of the vehicle. In other words, the rotational torque less than a predetermined value may be the rotational torque acting on the first camera regardless of the user's intention to rotate the first camera.

The term "the first camera is integrated with the first main body" means that at least the first lens constituting the first camera is fixed to the first main body.

Further, the first main body portion and the second main body portion may have a rectangular box shape, and more preferably a cylindrical shape. In the case of a cylindrical shape, the first main body and the second main body may have the same diameter.

(7) The second main body has a guide portion cut out to guide the second camera in the rotational direction, and at least a part of the outer edge of the guide portion is the second main body. It is characterized in that it is formed so as to be concave with respect to the outer peripheral surface of the portion.

According to this, since the outer edge of the guide portion of the second main body portion is formed so as to be concave with respect to the outer peripheral surface of the second main body portion, the second main body portion from the second main body portion in the guide portion is formed. The relative protrusion amount of the camera is increased, and the user can easily move the second camera. For example, the second main body portion is provided so that the amount of protrusion from the outer peripheral surface different from the outer peripheral surface of the outer peripheral peripheral region of the guide portion (for example, the outer peripheral surface on the opposite side of the guide portion (another outer peripheral surface)) is small. Even when the camera is formed, the outer edge of the guide portion is formed to be more concave than the other outer peripheral surfaces described above, so that the amount of protrusion of the second camera in the guide portion is larger than the amount of protrusion from the other outer peripheral surface. It can be made relatively large.

The outer edges of the concavely formed guide portion may be on both sides substantially parallel to the guide direction of the second camera.

(8) The first main body is formed in a substantially cylindrical shape, the second main body is formed in a substantially cylindrical shape, and the central axis of the second main body is the first main body. It is located coaxially with the central axis of the portion and can rotate to the first main body portion so as to rotate coaxially with the central axis of the first main body portion and relative to the first main body portion. It is characterized by being connected to.

According to this, since the first main body and the second main body are substantially cylindrical to each other, the second main body can be rotated with respect to the first main body without significantly changing the outer shape of the in-vehicle device. Can be made to. That is, the shooting direction of the second camera can be changed without significantly changing the outer shape of the in-vehicle device.

The outer diameters of the first main body and the second main body may be the same. By making the outer diameters the same, it is possible to further prevent the outer shape of the in-vehicle device from changing significantly when the second main body is rotated. For example, the in-vehicle device can be installed at a vehicle mounting location. Even if the second main body is rotated after the attachment, it is possible to prevent the second main body from interfering with other devices.

(9) The second camera is characterized in that it is rotatably supported by the second main body about a rotation axis orthogonal to the central axis of the second main body.

According to this, the tip side (of the central axis) of the central axis of the second main body in the axial direction is rather than configured so that the second camera rotates diagonally with respect to the central axis of the second main body. The second camera can be positioned on the side opposite to the side to which the first main body is connected in the axial direction), and for example, the rotation range in the horizontal direction can be increased.

(10) The end portion of the second main body portion in the axial direction opposite to the first main body portion is formed in a hemispherical shape so as to have a shape along the rotation of the second main body portion. It is characterized by being.

According to this, at the end of the second main body opposite to the first main body in the axial direction, the end of the second main body is not unnecessarily projected or dented by the second camera. Can be rotated along.

(11) The second main body is supported so as to be rotatable at least 180 degrees with respect to the first main body.

According to this, it is possible to take a picture outside the range of the angle of view of the first camera with the second camera only by rotating the second main body portion.

(12) When a predetermined or higher rotational torque is applied to the second main body, the second main body rotates with respect to the first main body, and a rotational torque less than a predetermined value is applied to the second main body. When applied to the main body portion, the second main body portion is provided with a main body holding means that is held by the first main body portion without rotating.

According to this, when a predetermined or more rotational torque is applied to the second main body, the second main body can rotate with respect to the first main body, and the rotational torque less than the predetermined is the second. When it is applied to the main body portion of 2, the second main body portion can be held at an arbitrary rotation position with respect to the main body portion.

The rotational torque equal to or higher than a predetermined value may be, for example, a rotational torque that acts on the second main body when the user picks and rotates the second main body. In other words, the rotational torque equal to or higher than a predetermined value may be a rotational torque that directly or indirectly acts on the second main body according to the intention of the user to rotate the second main body, for example, an operation of the user. It is preferable to use the power of a motor or the like operated by the engine or the rotational torque acted by the user's hand. The rotational torque less than the specified value is the rotational torque that acts on the second main body due to the vibration of the running vehicle or the like after the in-vehicle device is attached to the vehicle mounting location, or the second when the second camera is rotated. It is preferable to use the rotational torque that acts on the main body of the. In other words, the rotational torque less than a predetermined value may be the rotational torque that acts on the second main body portion regardless of the user's intention to rotate the second main body portion.

At this time, the first main body may be fixed to the vehicle mounting location directly or via a mounting bracket or the like. When it is fixed to the mounting location of the vehicle, it is preferable that the first camera is fixed so as to face the outside of the vehicle.

(13) When a rotation torque greater than or equal to a predetermined value is applied to the second camera, the second camera rotates with respect to the second main body, and a rotation torque less than a predetermined value is applied to the second camera. When the second camera is attached to the above, the second main body is provided with a camera holding means for holding the second camera.

According to this, when the second camera is given a rotational torque greater than or equal to a predetermined value, the second camera can rotate, and when a rotational torque less than a predetermined value is applied to the second camera, the second camera becomes rotatable. The second camera can be held by the second main body at an arbitrary rotation position.

The rotation torque equal to or higher than a predetermined value may be, for example, a rotation torque that acts on the second camera when the user picks and rotates the second camera. In other words, the rotational torque equal to or greater than a predetermined value may be a rotational torque that directly or indirectly acts on the second camera at the will of the user to rotate the second camera. For example, the operation is performed by the user's operation. It is preferable that the rotational torque is applied by the power of the motor or the like or the user's hand. The rotational torque less than the specified value is the rotational torque that acts on the second camera due to the vibration of the running vehicle or the like after the in-vehicle device is attached to the mounting location of the vehicle, or the second when rotating the second main body. It is good to use the rotational torque that acts on the camera. In other words, the rotational torque less than a predetermined value may be the rotational torque acting on the second camera regardless of the user's intention to rotate the second camera. At this time, it is preferable that the second main body is held by the main body holding means in the first main body at an arbitrary rotation position. For example, the rotational torque in (12) (for example, referred to as the first rotational torque) may be configured to be larger than the rotational torque in (13) (for example, referred to as the second rotational torque).

(14) The first main body is provided with a fixing means for fixing the first main body to a vehicle mounting position.

According to this, the first main body can be attached to the mounting location of the vehicle so that the first main body does not move unnecessarily. As the fixing means, for example, a mounting bracket that can be attached to the first main body may be used. The mounting bracket may be configured so that the orientation of the first main body (for example, the posture of the first main body at the mounting location of the vehicle) can be changed. In other words, it is preferable that the first main body portion can be fixed so that the shooting direction of the first camera can be changed.

Further, as the fixing means, a mounting bracket having a ring member that can be mounted on the first main body and a mounting member that can be mounted on the mounting location, and a fixing member that fixes the ring member to the first main body are provided. It is even better to prepare. The fixing member may be fixed by sandwiching the ring member with the first main body, and may be screwed into the first main body to be fixed. By screwing the fixing member into the first main body and sandwiching and fixing the ring member, for example, simply loosening the screwing of the fixing member loosens the holding of the ring member, and the first main body can be easily rotated. It will be possible. That is, it becomes easy to change between the fixed state and the movable state of the first main body.

Further, the first main body portion may be held by a fixing member so as not to rotate unnecessarily. For example, a rotational torque acting when rotating the second main body portion with respect to the first main body portion (for example, It is preferable that the rotation torque is larger than the above-mentioned first rotation torque (for example, the third rotation torque). In particular, the first main body may be non-rotatably fixed to the fixing member.

According to the present invention, it is possible to provide an in-vehicle device capable of photographing an arbitrary place with each of a plurality of cameras.

Note that FIGS. 1 to 3 show a state in which the second main body 200 is rotated 180 degrees with respect to the first main body 100. Further, in FIG. 3, electronic components and the like housed inside the first main body 100 are omitted.

FIG. 4A is a perspective view of the second main body 200 of the dashcam main body 10 according to the present embodiment, FIG. 4B is a front view of the second main body 200, and FIG. 4C is a top view. is there. FIG. 5 is an exploded assembly view of the second main body 200. 6 (a) and 6 (b) are perspective views of the bracket 20 of the drive recorder 1 according to the present embodiment, and FIG. 6 (c) is a side view. 7 (a) and 7 (b) are perspective views of the fixing member 30 of the drive recorder 1 according to the present embodiment, and FIG. 7 (c) is a side view.

As shown in FIGS. 1 (a) and 1 (b), the drive recorder 1 includes a drive recorder main body (hereinafter referred to as “drareco main body”) 10 having a substantially hemispherical tip formed into a substantially cylindrical shape, and a drareco main body. A mounting bracket (hereinafter, simply referred to as "bracket") 20 that is mounted on the base end of the dashcam body 10 so as to be relatively rotatable around the central axis X of the dashcam body 10, and the bracket 20 is the base of the dashcam body 10. A fixing member 30 for fixing to the end portion is provided.

The dashcam main body 10 has a first main body 100 to which the bracket 20 is rotatably mounted around the central axis X, and a second main body 100 rotatably supported by the first main body 100 about the central axis X. It includes a main body 200. That is, in the dashcam main body 10, the first main body 100 is relatively rotatable about the central axis X with respect to the bracket 20 attached to the vehicle mounting location, and the first main body 100 is relative to the first main body 100. , The second main body 200 is configured to be relatively rotatable about the central axis X. In the present embodiment, the dash cam main body 10 is formed to have a diameter of about 40 mm and an axial length of about 110 mm.

As shown in FIG. 2A, the first main body 100 is formed in a substantially cylindrical shape, and electronic components such as an image sensor constituting the first camera are built in (not shown). , The first lens 101 constituting the first camera is arranged on the outer peripheral surface 100a. As shown in FIG. 2B, the first lens 101 is arranged so as to face a direction orthogonal to the central axis X at a substantially central portion in the axial direction of the dashcam main body 10, and the main body portion 100. It is provided so as to slightly protrude from the outer peripheral surface 101a.

Further, when the drive recorder 1 is attached to the first lens 101 so that the central axis X is substantially parallel to the horizontal direction, the angle of view (horizontal direction) in the left-right direction displayed on the monitor is displayed. The angle of view) is larger than the second lens 211 of the second camera 210, which will be described later, and the vertical angle of view (vertical angle of view) displayed on the monitor is smaller than that of the second lens 211. It is used. The monitor referred to here is a monitor for displaying a captured image, and refers to, for example, a liquid crystal screen of a smartphone. By increasing the angle of view in the horizontal direction, it is possible to obtain a wide-angle image when shooting outside the vehicle, and by reducing the angle of view in the vertical direction, unnecessary outside light is emitted when shooting outside the vehicle. It is possible to reduce the incident. In the present embodiment, as the first lens 101, a lens having a horizontal angle of view of 100 degrees and a vertical angle of view of 75 degrees is used. The angle of view in the horizontal direction is preferably 90 degrees or more.

A mounting recess 102 to which the bracket 20 can be mounted is provided on the base end side of the first lens 101 of the first main body 100. When the bracket 20 is mounted, the mounting recess 102 is located on the same plane as the outer peripheral surface 21b (see FIG. 6) of the ring member 21 described later of the bracket 20 and the outer peripheral surface 100a of the first main body 100. As such, it is formed in a concave shape with respect to the outer peripheral surface 100a. That is, the mounting recess 102 is formed in a concave shape with respect to the outer peripheral surface 100a by the thickness of the ring member 21 of the bracket 20. Further, the outer diameter of the mounting recess 102 is formed so as to be slightly smaller than the inner diameter of the ring member 21 of the bracket 20 so that the bracket 20 can rotate.

At the boundary between the outer peripheral surface 100a and the mounting recess 102, the contact surface 103 that can come into contact with the side surface 21c (see FIG. 6) of the ring member 21 of the bracket 20 when the bracket 20 is mounted on the mounting recess 102 is at the center. It is erected in the direction orthogonal to the axis X. The contact surface 103 is partially formed with a meshing portion 104 in the circumferential direction, and the meshing portion 104 is composed of a plurality of concave portions 104a and convex portions 104b adjacent to each other.

On the base end side (base end portion of the dashcam main body 10) of the mounting recess 102 of the first main body portion 100, a screw portion 105 into which the fixing member 40 can be screwed toward the tip end side is provided. The screw portion 105 is formed in a concave shape with respect to the mounting recess 102, and a regulation surface 106 that regulates the amount of screwing of the fixing member 30 in the axial direction is formed at the boundary between the mounting recess 102 and the screw portion 105 as a central axis. It is erected in the direction orthogonal to X.

Here, the length of the mounting recess 102 in the axial direction of the central axis X is shorter than the length of the ring member 21 in the axial direction when the ring member 21 of the bracket 20 is mounted in the mounting recess 102. It is formed. Therefore, when the ring member 21 of the bracket 20 is mounted in the mounting recess 102, the above-mentioned regulation surface 106 is located inside the ring member 21. As a result, when the fixing member 30 is screwed into the screw portion 105 after mounting the ring member 21 in the mounting recess 102, the ring member 21 comes into contact with the fixing member 30 without being restricted by the regulation surface 106. It is sandwiched between the surface 103 and the ring member 21 can be fixed. On the other hand, if the screwing amount of the fixing member 30 is reduced, the ring member 21 can rotate on the mounting recess 102.

As shown in FIGS. 3A and 3B, a support portion 107 that rotatably supports the second main body portion 200 is provided at the tip end portion of the first main body portion 100 around the central axis X. Has been done. The support portion 107 is formed on the inner peripheral surface 100b of the first main body portion 100. That is, the first main body 100 rotatably supports the second main body 200 on the inner peripheral surface 100b side.

The support portion 107 guides the second main body portion 200 in the rotational direction about the central axis X, and also guides the second main body portion 200 so as not to fall off from the first main body portion 100 in the axial direction. A pair of protrusions 109a and 109b that can engage with the support portion 108 and the gear portion 222 of the second main body portion 200 to be described later to hold the second main body portion 200 at an arbitrary rotation position, and the first main body. A rotation regulating unit 110 that regulates the relative rotation amount of the second main body 200 with respect to the unit 100 is provided.

The guide support portion 108 is provided substantially parallel to the circumferential direction of the first main body portion 100 so that the second main body portion 200 rotates in the circumferential direction of the first main body portion 100, and the inner peripheral surface 100b It protrudes from the center axis X toward the central axis X. The pair of protrusions 109a and 109b project from the inner peripheral surface 100b side toward the central axis X, and elastically deform when a rotational torque of a predetermined value or more is applied, and a rotational torque of less than a predetermined value is applied. In some cases, it is formed so as not to be elastically deformed. Specifically, the pair of protrusions 109a and 109b are elastically deformed when a rotational torque is applied to the second main body 200 by the user in order to rotate the second main body 200, and the vehicle When rotational torque generated when vibration or rotation of the second camera 210 is applied to the second main body 200, elastic deformation is prevented. By elastically deforming the pair of protrusions 109a and 109b, the second main body 200 can move on the gear portion 222 of the second main body 200 to be engaged, and the second main body 200 can move with respect to the first main body 100. It becomes rotatable. On the other hand, since the pair of protrusions 109a and 109b are not elastically deformed, the engagement of the second main body 200 with the gear portion 222 is maintained, and the rotation position of the second main body 200 with respect to the first main body 100 is maintained. Is retained.

The rotation regulating unit 110 abuts on the regulating convex portion 224 provided on the second main body portion 200, which will be described later, to regulate the amount of rotation of the second main body portion 200 with respect to the first main body portion 100. Specifically, as shown in FIG. 3C, the rotation regulating portion 110 has regulating surfaces 110a and 110b that can come into contact with the regulating convex portion of the second main body portion 200, and is a guide support portion. The regulation surfaces 110a and 110b come into contact with the regulation convex portion 224 of the second main body 200 guided by 108, thereby restricting the rotation of the second main body 200.

The range of rotation regulated by the regulating surfaces 110a and 110b is, for example, a case where the second main body 200 is rotated in the vertical direction with respect to the first main body 100 in which the first lens 101 is oriented in the horizontal direction. For example, a position rotated slightly downward from the shooting direction of the first lens 101, and a position rotated slightly downward from a position rotated 180 degrees from above with respect to the shooting direction of the first lens 101. Until then, the regulating surfaces 110a and 110b are provided so that the second camera 210 can rotate. For example, the second main body 200 is provided so as to be rotatable 230 degrees in the vertical direction with respect to the first main body 100.

As shown in FIGS. 4A to 4C, the second main body 200 is formed in a substantially cylindrical shape having a substantially hemispherical tip, and is a cylindrical portion connected to the first main body 100. The outer diameter is formed to be substantially the same as the outer diameter of the first main body 100. By making the outer diameter of the cylindrical portion of the second main body 200 substantially the same as the outer diameter of the first main body 100, the outer diameter of the dashcam main body 10 is large even if the second main body 200 is rotated. It doesn't change. Therefore, even if the second main body 200 is rotated after the drive recorder 1 is attached to the vehicle mounting location, the second main body 200 may interfere with other devices or the like in the peripheral area of the mounting location. Can be prevented.

Further, the second main body 200 includes a second camera 210 capable of photographing the inside of the vehicle, and a case member 220 that rotatably supports the second camera 210.

The second camera 210 supports an electronic component (not shown) such as a second lens 211 and an image sensor for photographing the inside of the vehicle, and a camera housing that supports the second lens 211 and houses the electronic component. It is equipped with 212. In the present embodiment, the second lens 211 has a vertical angle of view when the drive recorder 1 is attached to a vehicle mounting location so that the central axis X is substantially parallel to the horizontal direction. A lens larger than 101 is used. For example, a lens having a horizontal angle of view of 45 degrees and a vertical angle of view of 30 degrees is used.

As shown in FIG. 5, the camera housing 212 includes a lens support portion 213 that supports the second lens 211, and a main body portion 214 to which the lens support portion 213 is connected. The lens support portion 213 is provided so as to protrude from the main body portion 214. The main body 214 is centered on a rotation axis Z (see FIG. 4A) orthogonal to the central axis X (see FIG. 4A) via a pair of rotation support members 230a, 230b (see FIG. 5). , It is rotatably supported by the case member 220.

Specifically, the main body portion 214 is formed in a substantially spherical shape in which both ends of the rotation shaft Z in the axial direction are cut, and a pair of rotation support members 230a and 230b are arranged in the cut portion. .. Further, the pair of rotation support members 230a and 230b have a fixing protrusion 231 fixed to a fixing recess 221 formed on the inner peripheral surface of the case member 220 and a sawtooth-shaped uneven portion provided on the inner surface of the main body portion 214. An engaging protrusion 232 that can be engaged with the 215 is provided, and the concave-convex portion 215 of the main body portion 214 is rotated by the engaging protrusion 232 while being fixed to the fixing recess 221 of the case member 220 by the fixing protrusion 231. Holds possible.

The engaging protrusion 232 protrudes toward the uneven portion 215 of the main body portion 214, and is elastically deformed when a rotational torque equal to or higher than a predetermined value is applied, and elastically deformed when a rotational torque less than a predetermined value is applied. It is formed so as not to. Specifically, in order to rotate the second camera 210, when a rotation torque is applied to the second camera 210 by the user, the second camera 210 is elastically deformed, and the vehicle vibrates or the second main body 200 is rotated. When a rotational torque generated in some cases is applied, elastic deformation does not occur. By elastically deforming the engaging protrusion 232, the uneven portion 215 of the main body portion 214 can move on the engaging protrusion 232, and the second camera 210 can rotate with respect to the case member 220. On the other hand, since the engaging projection 232 is not elastically deformed, the engagement between the uneven portion 215 of the main body 214 and the engaging projection 232 is maintained, and the rotational position of the second camera 210 with respect to the case member 220 is maintained.

In the present embodiment, the rotational torque for rotating the second camera 210 is set to be smaller than the rotational torque for rotating the second main body 200 described above.

The tip of the case member 220 is substantially hemispherical so that the lens support portion 213 can move along the outer shape of the case member 220 when the second camera 210 rotates around the rotation axis Z. It is formed. By making the tip of the case member 220 substantially hemispherical, the lens support portion 213 is hidden by the case member 220 or unnecessarily protrudes from the case member 220 even when the second camera 210 is rotated. Is prevented.

Further, in the case member 220, the gear portion 222 that can engage with the pair of protrusions 109a and 109b of the second main body 200 and the guide support 108 of the second main body 200 can be slidable. Rotation of the sliding groove 223, the regulation convex portion 224 capable of contacting the rotation regulation portion 110 of the second main body portion 200, and the lens support portion 213 of the second camera 210 around the rotation axis Z. It is provided with a guide portion 225, which is cut out so as to be able to guide in a direction.

The gear portion 222 is provided at the base end portion of the case member 220 substantially parallel to the rotation direction of the second main body portion 200. The sliding groove 223 is provided above the gear portion 222, is concave from the gear portion 222, and is formed substantially parallel to the rotation direction of the second main body portion 200. The regulation convex portion 224 is provided above the sliding groove 223, and is formed so as to be able to come into contact with the regulation surfaces 110a and 110b of the rotation regulation portion 110 when the second main body portion 200 rotates.

The guide portion 225 is formed so that the lens support portion 213 can move substantially in parallel with the central axis X. The guide range of the lens support portion 213 by the guide portion 225 is, for example, in the horizontal direction with respect to the first main body portion 100 in which the first lens 101 is oriented in the horizontal direction and the central axis X is substantially parallel to the horizontal direction. Taking the case of rotation as an example, the first lens 101 is slightly more than the position where the lens surface of the second lens 211 held by the lens support portion 213 is substantially parallel to the lens surface of the first lens 101. It is possible to guide from the position rotated to the side to the position where the side of the vehicle can be photographed by the second camera 210 when the drive recorder 1 is mounted at the mounting position of the vehicle.

Further, as shown in FIGS. 4B and 4C, the guide portion 225 has an outer edge 225a located on both sides of the rotation axis Z in the axial direction so as to be concave from the other outer peripheral surfaces of the case member 220. It is formed. By making the outer edges of the guide portion 225 on both sides in the axial direction concave, for example, the relative protrusion amount of the lens support portion 213 from the second main body portion 200 in the guide portion 225 increases, and the user can use the guide portion 225. The lens support portion 213 can be easily moved. Specifically, the lens is supported so that the amount of protrusion relative to the outer peripheral surface (for example, the outer peripheral surface on the opposite side of the guide portion 225) different from the outer peripheral surface in the vicinity of the guide portion 225 of the second main body portion 200 is reduced. Even when the portion 213 is formed, the outer edge of the guide portion 225 is formed to be concaver than the other outer peripheral surfaces, so that the amount of protrusion of the lens support portion 213 in the guide portion 225 is larger than the amount of protrusion from the other outer peripheral surface. Can also be relatively large.

As shown in FIGS. 6A to 6C, the bracket 20 includes a ring member 21 formed in an annular shape and a mounting member 22 that can be mounted at a mounting location of a vehicle.

The ring member 21 can be mounted in the mounting recess 102 of the first main body 100 from the base end side in the axial direction of the first main body 100, and can be rotated in the mounting recess 102 when mounted. As described above, the outer diameter of the inner peripheral surface 21a is formed to be slightly larger than the outer diameter of the outer peripheral surface of the mounting recess 102. Further, in the ring member 21, when the ring member 21 is mounted in the mounting recess 102 of the first main body 100, the outer peripheral surface 100a of the first main body 100 and the outer peripheral surface 21b of the ring member 21 are substantially the same plane. The outer diameter is formed to be substantially the same as the outer diameter of the first main body 100 (for example, the same diameter or slightly smaller or slightly larger) so as to be located above. In the present embodiment, the outer diameter of the ring member 21 is formed to be about 40 mm, which is the same diameter as the outer diameter of the outer peripheral surface 100a of the first main body 100.

Further, of the side surfaces 21c and 21d orthogonal to the inner peripheral surface 21a and the outer peripheral surface 21b of the ring member 21, when the ring member 21 is mounted in the mounting recess 102 of the first main body 100, the first main body 100 The side surface 21c that can come into contact with the above-mentioned meshing portion 104 is provided with a meshing portion 23 that can mesh with the meshing portion 104 of the first main body portion 100. The meshing portion 23 is composed of a plurality of serrated concave portions 23a and convex portions 23b formed adjacent to each other in the circumferential direction, and the plurality of concave portions 104a and convex portions of the meshing portion 104 of the first main body portion 100. By meshing with any of 104b, the relative rotation of the ring member 21 and the first main body 100 is restricted.

The mounting member 22 is formed in a rectangular plate shape, and has a mounting surface 22a to which double-sided tape for fixing to a vehicle mounting location is attached, and a connecting surface 22b connected to the ring member 21. There is. The mounting surface 22a is formed in a flat shape. The connecting surface 22b is connected to the outer peripheral surface 21b of the ring member 21 via the support leg portion 24 so that the mounting surface 22a is substantially parallel to the tangential direction of the outer peripheral surface 21b of the ring member 21.

As shown in FIGS. 7A to 7C, the fixing member 30 is formed in an annular shape, and the first main body 100 is formed from the base end side in the axial direction of the first main body 100. A screw groove 31 is formed on the inner peripheral surface 30a so that the screw portion 105 can be screwed. Further, in the fixing member 30, when the fixing member 30 is screwed into the screw portion 105 of the first main body portion 100, the outer peripheral surface 100a of the first main body portion 100 and the outer peripheral surface 30b of the fixing member 30 are substantially the same. The outer diameter is formed to be substantially the same as the outer diameter of the first main body 100 (for example, the same diameter or slightly smaller or slightly larger) so as to be located on a plane. In the present embodiment, the outer diameter of the fixing member 30 is formed to be about 40 mm, which is the same diameter as the outer diameter of the outer peripheral surface 100a of the first main body 100. Further, the side surface 30c orthogonal to the inner peripheral surface 30a and the outer peripheral surface 30b of the fixing member 30 is formed so as to be in contact with the side surface 21d of the ring member 21.

Here, the drive recorder 1 according to the present embodiment has a built-in known wireless LAN module, and by downloading a dedicated application to a smartphone or the like, the captured image is confirmed on the liquid crystal screen of the smartphone or the like. You can do it.

Further, in the drive recorder 1 according to the present embodiment, in order to change the shooting direction of the second camera 210 after being attached to the mounting location of the vehicle, the user can use the second main body with respect to the first main body 100. When the unit 200 is rotated by 90 degrees or more, the captured image can be rotated by 180 degrees around the normal of the image and displayed on a liquid crystal screen of a smart phone or the like. For example, a smartphone has a button to rotate an image, which flips when the button is pressed. The image inversion may be configured to be automatically inverted, for example. Further, the buttons are not limited to physical buttons, and may have a touch-type configuration provided on the liquid crystal screen.

With this configuration, for example, when checking the image taken by the second camera 210 with the smartphone after rotating the second main body 200, the image displayed on the smartphone is normally visually recognized. It can be an image in the orientation to be That is, it is possible to prevent the image displayed on the smartphone from becoming an image rotated around the normal line (an image in which the top and bottom are reversed) due to the rotation of the second camera 210. ..

Next, a method of attaching the drive recorder 1 according to the present embodiment will be described with reference to FIG. In the present embodiment, the case where the drive recorder 1 is attached to the windshield of the vehicle will be described as the attachment location of the vehicle. Further, in the present embodiment, the images taken by the first main body 100 and the second camera 210 are displayed on the smart phone by wireless LAN, and the user takes a picture while checking the image displayed on the smart phone. The case of adjusting the direction will be described. FIG. 8 is an explanatory diagram for explaining the installation of the drive recorder 1 according to the present embodiment.

First, as shown in FIG. 8, the ring member 21 of the bracket 20 is mounted on the mounting recess 102 of the dashcam body 10 from the base end side of the dashcam body 10. Since the ring member 21 of the bracket 20 is formed so that the outer diameter of the inner peripheral surface is slightly larger than the outer diameter of the outer peripheral surface of the mounting recess 102, the ring member 21 is mounted on the mounting recess 102. In, the bracket 20 is not fixed to the dash cam main body 10 and is in a rotatable state.

Next, the fixing member 30 is screwed into the screw portion 105 of the dash cam main body 10 from the base end portion side of the dash cam main body 10. When the fixing member 30 is screwed into the screw portion 105, the ring member 21 of the bracket 20 is sandwiched between the contact surface 103 of the first main body 100 and the side surface 30c of the fixing member 30, and the rotation of the bracket 20 is restricted. To. Further, the meshing portion 104 formed on the contact surface 103 and the meshing portion 23 formed on the side surface 21c mesh with each other, and the bracket 20 can be fixed to the dashcam main body 10. In this way, the bracket 20 is temporarily fixed to the dash cam main body 10 once.

Next, the bracket 20 temporarily fixed to the dash cam body 10 is attached to the windshield of the vehicle. In the present embodiment, the bracket 20 is attached to the windshield of the vehicle by using the double-sided tape attached to the attachment surface 22a of the attachment member 22 of the bracket 20.

Here, when the drive recorder 1 is attached to the windshield of a vehicle, the drive recorder 1 must be attached within a range of 20% or less in the vertical direction from the upper end of the windshield according to the safety standards of road transport vehicles and the like. Therefore, first, from the inside of the vehicle, the bracket 20 temporarily fixed to the dash cam main body 10 is attached within a range of 20% or less in the vertical direction from the upper end of the windshield. At this time, the bracket 20 is attached to the windshield so that the central axis X of the dashcam main body 10 is substantially parallel to the horizontal direction.

When the bracket 20 is attached to the windshield, the fixing member 30 screwed to the dashcam body 10 is then loosened to make the dashcam body 10 rotatable with respect to the bracket 20 attached to the windshield. When the dashcam main body 10 becomes rotatable, the smart phone is then made to display an image taken by the first main body 100. A dedicated application is downloaded to the smartphone in advance. Further, the drive recorder 1 is also connected to the power supply in advance. When the image taken by the first main body 100 is displayed on the smart phone, the user views the image projected on the smart phone and moves the first main body 100 in the vertical direction so as to obtain a desired image. Rotate to adjust the shooting direction.

When the desired image can be obtained by the first main body 100, the fixing member 30 is screwed into the screw portion 105, and the first main body 100 is non-rotatably fixed to the bracket 20. When the fixing member 30 is screwed into the screw portion 105, the meshing portion 104 formed on the contact surface 103 and the meshing portion 23 formed on the side surface 21c mesh with each other, so that the first main body portion 100 cannot rotate on the bracket 20. Is fixed to. Therefore, for example, the fixing of the first main body 100 to the bracket 20 is not loosened by the vibration of the traveling vehicle or the like. That is, the orientation of the image captured by the first main body 100 is not unnecessarily changed due to the vibration of the vehicle or the like.

Next, the second main body 200 is rotated from above to direct the second camera 210 into the vehicle. In the present embodiment, the second main body 200 is rotated 180 degrees with respect to the first main body 100. By rotating the second main body 200 by 180 degrees with respect to the first main body 100, the inside of the vehicle can be photographed by the second camera 210. At this time, the second main body 200 is held so as not to rotate due to the engagement between the pair of protrusions 109a and 109b of the first main body 100 and the gear portion 222 of the second main body 200. However, the user can rotate the second main body 200 by applying a rotational torque to the second main body 200. Further, when the second main body 200 is rotated 90 degrees or more with respect to the first main body 100, the image displayed on the smartphone is 180, which is the image taken by the second camera 210 around the normal line. It becomes a rotated image. That is, the smart phone displays an image in the same direction as the normal viewing direction.

Next, the user rotates the second camera 210 in the horizontal direction so that the desired location can be captured while looking at the image captured by the second camera 210 displayed on the smartphone. At this time, the second camera 210 does not rotate due to the engagement between the engaging protrusions 232 of the pair of rotation support members 230a and 230b and the serrated concave-convex portion 215 provided on the main body portion 214 of the camera housing 212. However, the user can rotate the second camera 210 by applying a rotation torque to the second camera 210. At this time, since the second camera 210 rotates with a rotation torque smaller than the rotation torque for rotating the second main body 200, the second main body 200 is held by the first main body 100. The state is maintained. Further, since the outer edge 225a of the guide portion 225 is formed in a concave shape, it is easy to move the second camera 210 even when it is attached to the windshield.

When the shooting direction of the second camera 210 is determined, the attachment of the drive recorder 1 to the windshield of the vehicle is completed. As a result, desired images outside the vehicle and inside the vehicle are captured in conjunction with the start and stop of the engine of the vehicle. Since the second main body 200 and the second camera 210 are not rotated by the rotational torque acting by the vibration of the running vehicle, the second camera 210 is caused by the vibration of the running vehicle or the like. The orientation of the image taken by the camera does not shift unnecessarily.

As described above, in the drive recorder 1 according to the present embodiment, the second main body 200 is supported so as to be rotatable 180 degrees or more with respect to the first main body 100, and the rotation direction of the second main body 200 The second camera 210 is rotatably supported with respect to the second main body 200 in a direction orthogonal to the above. Therefore, even when the drive recorder 1 is attached to the windshield so that the first lens 101 of the first main body 100 faces the outside of the vehicle, the second camera 210 can be rotated by rotating the second main body 200. It becomes possible to take a picture of the inside of the car, and by rotating the second main body 200 and the second camera 210, it is possible to take a picture of a desired place in the car. That is, the drive recorder 1 can capture desired images both inside and outside the vehicle.

Further, when the second main body 200 is rotated by 90 degrees or more, the drive recorder 1 rotates the image captured by the second camera 210 by 180 degrees in the normal direction of the image, and is an image in a direction that is normally visually recognized. Is displayed on the smartphone. Therefore, even when the second main body 200 is rotated, it is easy to adjust the imaging direction of the second camera 210 while looking at the smart phone.

Further, in the drive recorder 1, a lens having a large angle of view in the horizontal direction and a narrow angle of view in the vertical direction is used for the first lens 101 of the first main body 100 for photographing the outside of the vehicle. Therefore, it is possible to take a wide-angle image of the outside of the vehicle while reducing the incident of external light.

Further, in the drive recorder 1, the first main body 100 and the second main body 200 are formed in a substantially cylindrical shape having substantially the same diameter, and each is configured to rotate relatively on the same axis. Therefore, for example, even when the first main body 100 and the second main body 200 are rotated, there is almost no change in the outer diameter of the drive recorder 1, and even when the drive recorder 1 is attached to the vehicle mounting location, the rotation is caused. It is possible to prevent interference with other devices and the like.

Further, in the drive recorder 1, the outer edge 225a of the guide portion 225 of the second main body portion 200 is formed in a concave shape. Therefore, the user can easily rotate the second camera 210 without unnecessarily projecting the lens support portion. For example, the second camera 210 can be easily rotated even after the drive recorder 1 is attached to the mounting location of the vehicle.

Further, the drive recorder 1 is configured such that the bracket 20 is rotatably attached to the first main body 100, and the bracket 20 is sandwiched and fixed between the fixing member 30 and the first main body 100. Therefore, even after the bracket 20 is attached to the windshield of the vehicle, the first main body 100 can be easily rotated to adjust the shooting direction by the first main body 100.

Further, the second camera 210 is configured to rotate in a direction orthogonal to the rotation direction of the second main body 200. Therefore, for example, rather than rotating the second camera 210 diagonally with respect to the rotation direction of the second main body 200, the tip side of the central axis X of the second main body 200 in the axial direction (of the central axis X). The second camera 210 can be positioned on the side opposite to the side to which the first main body 100 is connected in the axial direction, and for example, the rotation range in the horizontal direction can be increased.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments. In addition, the effects described in the embodiments of the present invention merely list the most preferable effects arising from the present invention, and the effects according to the present invention are not limited to those described in the embodiments of the present invention.

For example, in the present embodiment, the drive recorder 1 has been used as an example of the in-vehicle device, but the present invention is not limited thereto. The in-vehicle device according to the present invention may be used, for example, in a navigation device having a plurality of cameras. By using it in a navigation device, it is possible to store captured images (moving images or still images) in association with map information of the navigation function. For example, a map can be constructed by using an image taken instead of a picture.

Further, in the present embodiment, the drive recorder 1 having two cameras has been described as an example of the in-vehicle device, but the present invention is not limited thereto. The in-vehicle device according to the present invention may be, for example, a drive recorder having three or more cameras, any two of the three or more cameras, or each having the same configuration as the present invention.

Further, in the present embodiment, the second camera 210 is configured to be rotatable in a direction orthogonal to the rotation direction of the second main body 200, but the present invention is not limited to this. The in-vehicle device according to the present invention may have a configuration in which the second camera is rotatably supported by the second main body in any direction with respect to the second main body. For example, the main body of the camera housing of the second camera may be configured by a ball joint that can rotate around the center of rotation, and the camera housing may be rotatably supported by a case member. Further, the second camera may be rotatably supported by the second main body so as to be rotatable in a direction that intersects the rotation direction of the second main body without being orthogonal to each other. ..
