Description

  The present invention relates to a room mirror equipped with a drive recorder unit.

  The drive recorder can be fixed by adhering a bracket to the inner surface of the front windshield, but there is a problem that the drive recorder falls due to impact or due to deterioration of the adhesive due to aging. For this reason, a camera in which the camera is integrated with the base of the room mirror has been proposed (Patent Document 1).

JP 2010-195113 A

  However, the above-described conventional camera-integrated room mirror has a problem that there is no space for providing a display on the drive recorder, and even if a display is provided, the room mirror interferes with the display of the drive recorder.

  The problem to be solved by the present invention is that a room with a drive recorder that can shoot a front field of view with a drive recorder and visually recognize a rear field of view with a room mirror during normal driving, and can visually check the display of the drive recorder as necessary. Is to provide a mirror.

  The present invention attaches the drive recorder to the stay on the back side of the rearview mirror body, and the rearview mirror body is visually inspected at the first position where the rear view of the vehicle can be seen by the mirror and the display of the drive recorder attached on the rear side. The above-described problem is solved by configuring the second position to be rotatable.

  In the room mirror with a drive recorder of the present invention, the room mirror body is rotated to the first position during normal running. As a result, it is possible to capture the front view by the drive recorder and view the rear view by the room mirror. On the other hand, if the room mirror body is rotated to the second position as necessary, the display of the drive recorder can be visually observed.

It is a perspective view showing one embodiment of a room mirror with a drive recorder concerning the present invention. It is the perspective view which looked at the room mirror with a drive recorder of Drawing 1 from the back. It is the top view which looked at the room mirror with a drive recorder of Drawing 1 from the upper surface. It is a center longitudinal cross-sectional view which shows the room mirror with a drive recorder of FIG. It is a center longitudinal cross-sectional view which shows other embodiment of the room mirror with a drive recorder which concerns on this invention. It is a figure for demonstrating the angle adjustment direction of a drive recorder or a mirror.

  Hereinafter, an embodiment of a room mirror 1 with a drive recorder according to the present invention (also a drive recorder with a room mirror from a different viewpoint) will be described. The room mirror 1 with a drive recorder in this example is mounted on the indoor side of a front windshield (also referred to as a front windshield) 3 of an automobile, and the driver observes the rear view of the vehicle with the mirror 11 and at the same time the drive recorder 2 Capture and record the forward field of view while driving. In the following description, in order to describe an embodiment of the room mirror 1 with a drive recorder mounted on an automobile, the angle adjustment direction of the lens optical axis L of the mirror 11 and the drive recorder 2 is defined as shown in FIG. To do. That is, as shown in FIG. 6, among the X axis, the Y axis, and the Z axis orthogonal to each other, the shooting direction (that is, the lens optical axis L of the drive recorder 2) is the Y axis direction, the vertical direction is the Z axis direction, The direction (vehicle width direction) is the X axis direction, the rotation direction around the X axis is called the pitch direction, the rotation direction around the Y axis is called the roll direction, and the rotation direction around the Z axis is called the yaw direction.

  As shown in FIGS. 1 to 4, a room mirror 1 with a drive recorder of this example (hereinafter also simply referred to as a room mirror 1) includes a mirror 11 and a housing 12 that supports the mirror 11. 13 and a stay 14 to which one end 14a is attached to the front window 3 of the vehicle and the rear mirror body 13 is attached to the other end 14b. The housing 12 and the stay 14 can be made of plastic or metal, but are preferably made of plastic from the viewpoint of weight.

  The room mirror body 13 is fixed to the front windshield 3 by a stay 14. That is, as shown in the cross-sectional view of FIG. 5, the fixing seat 16 is firmly fixed to the inner surface of the front windshield 3 using an adhesive or the like. The base 15 is attached to the inner surface of the front windshield 3 by inserting the engaging portion 17 of the base 15 into the fixed seat 16. In addition, the rear-view mirror 1 of the present invention may be attached to the inner surface of the front windshield 3 as shown, or may be attached to the roof inner panel depending on the vehicle type or vehicle type.

  One end 141 of the stay 14 has a spherical shape, and a concave spherical surface 151 corresponding to the one end 141 of the spherical shape is formed on the base 15, and these are fitted to form a spherical bearing (universal joint). Thereby, the stay 14 can swing in a three-dimensional direction with respect to the base 15 fixed to the inner surface of the front windshield 3. However, the one end 141 of the stay 14 and the concave spherical surface 151 of the base 15 are firmly fitted in comparison with the fitting force between the other end 142 of the stay 14 described later and the concave spherical surface 123 of the housing base 122. Unless the stay 14 is rotated by force, the stay 14 does not swing.

  The other end 142 of the stay 14 has a spherical shape similar to the one end 141 described above, and a concave spherical surface 123 corresponding to the spherical shape is formed on a housing base 122 described later, and a spherical bearing ( Universal joint). Thereby, the rearview mirror main body 13 can swing in the three-dimensional direction with respect to the stay 14. As described above, the fitting force between the other end 142 of the stay 14 and the concave spherical surface 123 of the housing base 122 is set to be weaker than the fitting force between the one end 141 of the stay 14 and the concave spherical surface 151 of the base 15. Therefore, if the driver grips the rearview mirror body 13 and rotates it in a desired direction with an appropriate force, only the rearview mirror body 13 swings and is adjusted to a desired angle. In order to swing the stay 14 itself, the stay 14 may be gripped and swinged with respect to the concave spherical surface 151 of the base 15.

  Note that the stay 14 of this example has a rod-like bent shape because of the relationship between the inclination angle of the front windshield 3 and the rear view by the mirror 11, but the stay 14 according to the present invention is limited to this bent shape. It is not a thing. Depending on the inclination angle of the front windshield 3 and the mounting position of the rearview mirror 1, a linear stay 14 may be used.

  The room mirror body 13 of this example includes a mirror 11 that captures a rear view, a housing 12 that supports the mirror 11, a housing substrate 121 provided inside the housing 12, and a housing that is fixed to the housing substrate 121. A base 122. Among these, the housing substrate 121 forms a skeleton member of the room mirror body 13, and the housing 12 and the housing base 122 are fixed to the housing substrate 121, so that the housing substrate 121 is fixed to the other end 142 of the stay 14. The housing 12 and the housing base 122 swing together. In addition, although the mirror 11 of this example is being fixed to the housing 12, you may employ | adopt an anti-glare mirror structure by a well-known method.

  As shown in FIGS. 2 and 3, a recess 18 is formed in the back surface of the housing 12 of this example, and the drive recorder 2 is attached to the stay 14 while being received in the recess 18. In the left and right spaces S1 and S2 other than the recess 18 in the housing 12 shown in FIG. 3, a drive circuit board and a light receiving sensor for automatically driving the anti-glare mechanism of the mirror 11, a so-called keyless entry system (the key is a keyhole). The receiver of the system that can lock and unlock the door lock by operating the entry key even if it is not plugged in. However, when it is not necessary to store these components, the entire housing 12 may be formed thin instead of providing the recess 18.

  As shown in FIGS. 1 and 2, the drive recorder 2 of this example is provided with a lens 22 of the imaging device on one main surface of the casing 21 (the front surface of the vehicle shown in FIG. 2, the front surface of the drive recorder 2). A liquid crystal display 23 and operation buttons 25 are provided on the other main surface (the rear surface of the vehicle shown in FIG. 1, the back surface of the drive recorder 2). A bracket 24 is attached to the upper surface of the housing 21 for fixing to the stay 14 via the rotating portion 27. The drive recorder 2 is fixed to the stay 14 by sandwiching the stay 14 between the pair of curved portions of the bracket 24 and tightening the tip of the bracket 24 with the bolt 26. In addition, since the rotation part 27 which can rotate the housing | casing 21 in a pitch direction (rotation direction centering on the X-axis) is provided in the base end of the bracket 24, the drive recorder 2 is attached to the stay 14. The elevation angle of the lens 22 can be adjusted even in a state where the lens 22 is fixed.

  The drive recorder 2 of this example receives electric power from a vehicle battery or electric power from a dry battery or a secondary battery, and drives the imaging circuit to shoot a moving image of a forward view at a predetermined frame rate. Then, the photographed image is recorded on a recording medium such as an SD card at a predetermined timing. The shooting timing and recording timing of the drive recorder according to the present invention are not particularly limited. For example, start shooting as soon as the vehicle starts running, write to the recording medium in the order of shooting, and overwrite the old recording when the capacity of the recording medium is exceeded, start shooting when the vehicle starts running, It is possible to use a device that writes images on a recording medium in the order of shooting and holds images before and after the start of a shooting trigger sensor such as a shock sensor.

Next, the effect of the room mirror 1 with a drive recorder of this example is demonstrated.
The spherical bearing (universal joint) constituted by the other end 142 of the stay 14 and the concave spherical surface 123 of the housing base 122 in this example rotates at a large angle at least in the pitch direction (rotation direction with the X axis as the rotation center). It is configured to move. In conventional room mirrors, the driver only needs to be able to see the rear field of view with the mirror 11, so the swing angle of the mirror 11 is limited to a very limited range. On the other hand, in the rearview mirror 1 with a drive recorder of this example, the upper side of the concave spherical surface 123 of the housing base 122 in the overlapping range where the housing base 122 and the other end 142 of the stay 14 are fitted as shown in FIG. The edge 124 is scraped off.

  As a result, as shown by a two-dot chain line in FIG. 5, the room mirror main body 13 can be largely rotated upward in the pitch direction with the other end 142 of the stay 14 as the rotation center. Although the driver's line of sight Ey is indicated by an arrow on the right side of FIG. 5, when the rearview mirror main body 13 is rotated to a position indicated by a two-dot chain line (second position according to the present invention), the driver It is possible to visually observe the liquid crystal display 23 provided on the screen and to operate the operation buttons 25. And if the mirror 11 is rotated to a regular position (1st position which concerns on this invention) as shown with a continuous line in FIG. 4, the function as a normal room mirror will be exhibited.

  As described above, according to the room mirror 1 with a drive recorder of the present example, the drive recorder 2 is attached to the stay 14, so that even if the passenger including the driver adjusts the angle of the room mirror body 13, the drive recorder The second lens optical axis L is maintained. For this reason, an operation for adjusting the range optical axis L of the drive recorder 2 again becomes unnecessary.

  Further, according to the rear mirror 1 with a drive recorder of this example, since the drive recorder 2 is attached to the rear surface of the rearview mirror main body 13, the drive recorder 2 is operated during normal driving when the rearview mirror main body 13 is in a regular position. This prevents the sight of passengers including passengers from being obstructed.

  Further, according to the room mirror 1 with the drive recorder of the present example, when the mirror 11 is not used, if the room mirror body 13 is rotated upward in the pitch direction as necessary (second position), the drive recorder 2 The liquid crystal display 23 provided on the back surface of the camera can be viewed and the operation buttons 25 can be operated.

  FIG. 5 is a cross-sectional view showing another embodiment of the room mirror 1 with a drive recorder according to the present invention, and is a cross-sectional view corresponding to FIG. In the embodiment shown in FIG. 5, the upper edge 124 of the concave spherical surface 123 of the housing base 122 is scraped out of the overlapping range where the housing base 122 shown in FIG. 4 and the other end 142 of the stay 14 are fitted. Instead, a hinge 19 that rotates the housing 12 including the mirror 11 is provided with respect to the housing base 122. That is, in the rearview mirror 1 with a drive recorder of this example, the housing base 122 and the housing 12 are connected to each other via the hinge 19 so as to be pivotable. The first position according to the present invention is set, and the housing 12 can be rotated to a retracted position (second position according to the present invention) indicated by a two-dot chain line as necessary. However, the hinge 19 has a certain amount of rotational load and is configured not to move slightly due to vibrations of the vehicle.

  According to the room mirror 1 with the drive recorder of this example configured as described above, in addition to the same effects as the embodiment shown in FIG. 4, the visual observation of the liquid crystal display 23 and the operation of the operation buttons 25 are finished. If the room mirror body 13 is returned to the original normal position, there is an advantage that it is not necessary to adjust the angle of the mirror 11 again.
