[0001] The present invention relates to a digital mirror attachment tool for attaching a digital mirror to an existing rearview mirror. [Background technology]

[0002] Digital mirrors, which display images captured by a camera on a display device, are becoming increasingly popular as a replacement for the conventional optically projected mirror installed in the interior of a vehicle to allow the driver to see behind the vehicle. Digital mirrors are sometimes installed separately from the existing rearview mirror on the front panel, but are often installed in such a way that they cover the front of the existing rearview mirror, and various installation methods have been proposed.

[0003] The digital mirror mounting structure described in Patent Document 1 includes a digital mirror main body 16 with engaging edges (16b to 16g) around its periphery, and two separate rear covers 18L and 18R that are attached to cover the existing rearview mirror 14 (Figure 2).

[0004] In the digital mirror described in Patent Document 2, the upper and lower gripping pieces 20 and 30 provided on the back surface of the display device 11 clamp the top and bottom of the existing rearview mirror Ma, and a binding part 40 (e.g., a rubber band) is attached by spanning the tip of the upper gripping piece 20 and the tip of the lower gripping piece 30 (Figures 3 and 6).

[0005] Patent Document 3 relates to a drive recorder, and describes that four clamping portions 16A to 16D provided on the back surface of the drive recorder 1 grip and fix the edge of the rearview mirror 2 (FIG. 1). [Prior art documents] [Patent documents]

[0007] The device described in Patent Document 1 had the problem that the parts of the mounting structure were separated into the front and back, making the mounting work complicated.

[0008] The invention described in Patent Document 2 had the problem that the gripping pieces were conspicuous and spoiled the aesthetic appearance of the rearview mirror. In addition, there was a problem that there was no component that abutted against the left and right ends of the existing mirror, which made it prone to slippage due to vibrations while driving.

[0009] The invention described in Patent Document 3 had the problem that the clamping portion was noticeable and spoiled the aesthetic appearance of the rearview mirror. Also, because the clamping portion simply clamped the existing rearview mirror, it was prone to slippage due to vibrations while driving.

[0010] An object of the present invention is to provide a digital mirror attachment tool that can be easily and securely attached to an existing rearview mirror. [Means for solving the problem]

[0011] The digital mirror mounting fixture of the present invention covers the front of the existing rearview mirror and includes a front panel that houses a digital mirror display unit and a display unit near one end of the rear of the front panel.

[0015] Below, we will explain a digital mirror fitting 1, one embodiment of the present invention, with reference to the drawings. Fig. 1 is a plan view of the digital mirror fitting 1, Fig. 2 is a bottom view of the digital mirror fitting 1, Fig. 3 is a front view of the digital mirror fitting 1, Fig. 4 is a rear view of the digital mirror fitting 1, Fig. 5 is a cross-sectional view of the digital mirror fitting 1 taken along line AA in Fig. 1, and Fig. 6 is a perspective view showing the left contact part 30 attached to the main body 11. In the following explanation, "left" and "right" are used based on Fig. 1, but the left and right can also be reversed.

[0016] The existing rearview mirror 2 is a component installed inside the vehicle interior to enable the driver to see behind the vehicle, and uses an optical method to enable the driver to see behind the vehicle. The existing rearview mirror 2 is installed, for example, by hanging it from the ceiling of the vehicle interior using a stay.

[0017] The digital mirror display unit 10 is configured with a liquid crystal panel or the like, and displays an image of the rear of the vehicle captured by a camera. The digital mirror display unit 10 is electrically connected to the camera and a power source by a cable.

[0018] The digital mirror attachment 1 comprises a main body 11 and a left contact portion 30 (an example of an other end contact portion) that is configured separately from the main body 11. The main body 11 comprises a front panel 12, a holding portion 13, a right contact portion 14 (an example of one end contact portion), an upper flange 15, and a lower flange 16. The front panel 12, holding portion 13, right contact portion 14, upper flange 15, and lower flange 16 are integrally formed.

[0019] The front panel 12 is a plate-shaped member that houses the digital mirror display unit 10, and is shaped to cover the entire front surface of the existing rearview mirror 2. A recess that matches the shape of the digital mirror display unit 10 is provided on the front of the front panel 12, and the digital mirror display unit 10 is housed in this recess.

[0020] Two windows 21 and 22 are provided near the center in the left-right direction at the top of the front panel 12 at positions corresponding to the information display unit provided on the existing rearview mirror 2. The information display unit is, for example, an indicator that shows the operating status of an ETC (Electronic Toll Collection System) device, and by providing the windows 21 and 22, the driver can see the information display unit even when the existing rearview mirror 2 is covered by the front panel 12. The windows 21 and 22 may be hollow, or may be covered with a material that transmits the light of the indicators.

[0021] A flange-shaped right abutment portion 14 is provided along the entire back side of the right end of the front panel 12. One end of the right abutment portion 14 is connected to the upper right end of the extension retaining portion 13 at the upper end of the front panel 12. The other end of the right abutment portion 14 is connected to the lower right end of the extension retaining portion 13 at the lower end of the front panel 12. When the digital mirror mounting fixture 1 is attached to the existing rearview mirror 2, the inner surface of the right abutment portion 14 abuts against the right side of the existing rearview mirror 2.

[0022] A holding portion 13 shaped to surround the existing rearview mirror 2 is provided near the right end of the front panel 12. One end of the holding portion 13 is connected to the upper end of the front panel 12, and the other end is connected to the lower end of the front panel 12, forming a single unit between the front panel 12 and the holding portion 13. The inner shape of the holding portion 13 is substantially the same as the outer shape of the portion of the existing rearview mirror 2 that is held by the holding portion 13, so that the inner surface of the holding portion 13 and the outer surface of the existing rearview mirror 2 are in close contact. The width of the holding portion 13 (the dimension in the left-right direction in FIG. 1 ; the same applies below) is preferably about 1 / 4 the width of the existing rearview mirror 2. In this way, by positioning the holding portion 13 closer to one of the left-right ends and making its width smaller than the width of the existing rearview mirror 2, it can be attached without interfering with the stays of the existing rearview mirror 2, etc.

[0023] The holding portion 13 has a built-in drive recorder 23, and is provided with a speaker 24 on the upper surface of the holding portion 13 and a speaker 25 and an indicator 26 on the lower surface. In addition, a slot 27 into which a storage medium for the drive recorder 23 is inserted is provided so as to open on the right end side of the holding portion 13.

[0024] An upper flange 15 is provided on the upper rear side of the front panel 12, in the center in the left-right direction. The right end of the upper flange 15 is connected to the left end of the holding member 13. A lower flange 16 is provided on the lower rear side of the front panel 12, in the center in the left-right direction. The right end of the lower flange 16 is connected to the left end of the holding member 13. The height of the upper flange 15 (the dimension in the vertical direction in Figure 1, the same applies below) and the height of the lower flange 16 are the same, and are about 1 / 3 of the height of the right abutment portion 14.

[0025] The left abutment portion 30 is a roughly U-shaped member when viewed from the front, and includes a cover portion 33 that abuts against the left side of the existing rearview mirror 2 when the digital mirror mounting fixture 1 is attached to the existing rearview mirror 2, an upper connecting portion 31 that is connected to the front panel 12, and a lower connecting portion 32 that is connected to the front panel 12.

[0026] The height of the upper joint 31 matches the height of the upper flange 15, and the right end of the upper joint 31 abuts against the left end of the upper flange 15. The height of the lower joint 32 matches the height of the lower flange 16, and the right end of the lower joint 32 abuts against the left end of the lower flange 16. It is preferable that the shape of the inner surface of the cover part 33 when viewed from the front matches the shape of the left end of the existing rearview mirror 2.

[0027] The height of the side portion 33a of the cover member 33 is set to be high enough to hold the existing rearview mirror 2. The height of the upper surface portion 33b of the cover portion 33 gradually decreases in a smooth curve from the left and right ends toward the center, and becomes equal to the height of the upper flange 15 at the position where the upper flange 15 is connected. The height of the lower surface portion 33c of the cover portion 33 gradually decreases in a smooth curve from the left and right ends toward the center, and becomes equal to the height of the lower flange 16 at the position where the lower flange 16 is connected.

[0028] A screw hole 34 is provided near the connection portion of the upper joint 31 with the cover portion 33, and a screw hole 35 is provided near the connection portion of the lower joint 32 with the cover portion 33, respectively.

[0029] The shape of the inner surface of the holding portion 13 of the digital mirror mounting fixture 1 matches the shape of the outer surface of the existing rearview mirror 2, so the holding portion 13 can firmly hold the existing rearview mirror 2. In addition, the right abutment portion 14 abuts against the right side of the existing rearview mirror 2, and the left abutment portion 30 abuts against the left side of the existing rearview mirror 2, restricting movement in the left-right direction. Furthermore, the upper flange 15 and lower flange 16 restrict movement in the up-down direction. Therefore, the digital mirror mounting fixture 1 will not shift or come off due to vibrations while the car is running.

[0030] In the digital mirror fixture 1, the front panel 12 of the main body 11, the right abutment portion 13, and the holding portion 14 are formed as a single unit, with no seams or conspicuously protruding parts. Additionally, although the left abutment portion 30 is separate from the main body, the height of the upper flange 15 and the upper joint portion 31, and the height of the lower flange 16 and the lower joint portion 32 are aligned, and the height is kept small, so the seams are not noticeable. This gives the digital mirror fixture 1 an aesthetically pleasing appearance.

[0031] Figures 7(a) to (c) are diagrams explaining the procedure for attaching the digital mirror mounting fixture 1 to the existing rearview mirror 2. First, align the rear face of the front panel 12 with the front face of the existing rearview mirror 2, and slide the main body 11 toward the existing rearview mirror 2 as shown by arrow A in Figure 7(a) until the right abutment part 14 abuts against the right side of the existing rearview mirror 2, resulting in the state shown in Figure 7(b). In this state, the inner surface of the holding part 13 and the outer surface of the existing rearview mirror 2 are in tight contact.

[0032] Next, align the front surface of the left contact portion 30 with the rear surface of the front panel 12, and slide the left contact portion 30 toward the existing rearview mirror 2 as shown by arrow B in FIG. 7(b) until the right end of the upper joint portion 31 and the left end of the upper flange 15, and the right end of the lower joint portion 32 and the left end of the lower flange 16, respectively, to reach the state shown in FIG. 7(c). In this state, the inner surface of the cover portion 33 and the left side surface of the existing rearview mirror 2 are in close contact. Then, insert screws into the screw holes 34 and 35 to connect the left contact portion 30 to the main body 11. In this way, the digital mirror mounting fixture 1 can be attached to the existing rearview mirror 2 with a simple procedure.

[0033] The digital mirror fixture 1 can be implemented as a fixture alone, or as a digital mirror integrated with the fixture. [Explanation of symbols]
