DETAILED DESCRIPTION OF THE INVENTION
DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to FIGS. The inner mirror 1 shown in this embodiment has a liquid crystal monitor (monitor) 3 disposed on the back side of the mirror glass 2 as shown in FIGS. It is characterized by being configured to be fixed by pressing with a strong force. That is, the liquid crystal monitor 3 is fixed by being pressed against the back surface of the mirror glass 2 by an elastic force by an elastic sponge body (foamed resin body) 4. The sponge body 4 is positioned by a rib 50 of the housing 5 that holds the mirror glass 2.
[0015]
Hereinafter, the above configuration will be described in more detail. That is, as shown in FIGS. 1 to 4, the housing 5 covers the entire side and rear of the mirror glass 2, and completely prevents light from hitting the back surface of the mirror glass 2. The connecting portion between the mirror glass 2 and the housing 5 is also completely sealed by the rim 6. Therefore, light from the outside is not directly incident on the back surface of the mirror glass 2.
[0016]
Since the mirror glass 2 is constituted by a kind of half mirror and light does not enter from the back side in a normal use state, the mirror glass 2 acts as a normal rear confirmation mirror that reflects only the light from the front side. It has become. However, since the light passes through the mirror glass 2 when the liquid crystal monitor 3 is displayed, the display on the liquid crystal monitor 3 can be seen through the mirror glass 2.
[0017]
As shown in FIG. 4, the housing 5 is integrally formed of resin. Inside the concave shape, there are a plurality of ribs 50 and five bosses 56 on the back surface 5a and the side surface 5b. Are provided integrally. The ribs 50 are arranged at the periphery of the first rib 51 arranged at the center in the width direction of the housing 5, a plurality of second ribs 52 arranged around the first rib 51, and a plurality of ribs 50. It is divided into a third rib 53 and a plurality of fourth ribs 54 for positioning the liquid crystal monitor 3.
[0018]
The first rib 51 and the boss 56 are reinforcements for fixing to a stay (not shown) provided in the vehicle, and a hole 56a for screwing a screw (not shown) to each boss 56. Is formed.
[0019]
The second rib 52 includes a horizontal rib 52a extending in parallel to the horizontal direction from the first rib 51, a vertical rib 52b extending in the vertical direction so as to connect the front ends of the horizontal rib 52a, and a lower horizontal rib 52a. A lower longitudinal rib 52c extending vertically downward from the boss 56 positioned at the base end of the rib 52a and an oblique rib 52d extending obliquely downward from the boss 56 are provided. The second rib 52 is also a reinforcement of the housing 5.
[0020]
The third rib 53 is formed so as to protrude a predetermined amount inward from the side surface 5b and to protrude from the back surface 5a to the front surface side by a predetermined amount. These third ribs 53 are also reinforcing the housing 5. However, some of the third ribs 53 also serve as the fourth ribs 54.
[0021]
The fourth ribs 54 include a plurality of upper positioning ribs 54a that also serve as the third ribs 53, a plurality of lower positioning ribs 54b that also serve as the third ribs 53, the first ribs 51, and the lower vertical ribs 52c. A left positioning rib 54c that protrudes toward the liquid crystal monitor 3 and a right positioning rib 54d that is disposed at each of the upper and lower positions and protrudes from the rear surface 5a to the front surface side.
[0022]
The upper positioning rib 54a, the lower positioning rib 54b, and the left positioning rib 54c are respectively provided with guide side portions 55a that guide the upper side surface, the lower side surface, and the left side surface of the liquid crystal monitor 3, and the bottom surface of the liquid crystal monitor 3 A guide bottom portion 55b for guiding the above is formed. The guide side portion 55a and the guide bottom portion 55b are also formed on the lower portion of the vertical rib 52b.
[0023]
Further, as shown in FIGS. 4 and 5A, the right positioning rib 54d includes a parallel rib 54e arranged in parallel to the side surface of the liquid crystal monitor 3, and the liquid crystal monitor 3 from each of the upper and lower positions of the parallel rib 54e. And a vertical rib 54f protruding vertically to the side. The upper ends of the vertical ribs 54f are the above-described guide bottom portions 55b, and the surfaces of the parallel ribs 54e facing the liquid crystal monitor 3 above the guide bottom portions 55b are the above-described guide side portions 55a. Further, as shown in FIG. 5B, the right positioning rib 54d does not have one vertical rib 54f at the center of the parallel rib 54e, so that the warping A of the guide side portion 55a can be prevented. It can be done.
[0024]
Each guide side portion 55a described above is formed in a taper shape so as to gradually move away from the side surface of the liquid crystal monitor 3 toward the front surface side. That is, each guide side portion 55 a is configured so that the liquid crystal monitor 3 can be easily accommodated in the housing 5. In addition, each guide side portion 55a is configured to reliably position the liquid crystal monitor 3 housed in the housing 5 at a predetermined position in the mirror glass 2. Further, each guide bottom 55 b is slightly separated from the bottom surface of the liquid crystal monitor 3 because the bottom surface of the liquid crystal monitor 3 is pressed by the sponge body 4. However, the guide bottom 55b serves as a stopper when the liquid crystal monitor 3 is pushed in during assembly.
[0025]
As shown in FIGS. 1 to 4, the sponge body 4 is formed of a foamed resin having elasticity such as urethane foam. When the liquid crystal monitor 3 is attached, the sponge body 4 is compressed and deformed, and the bottom surface of the liquid crystal monitor 3. Necessary and sufficient elastic force is applied. Further, as shown in FIG. 4, the sponge body 4 is divided into a part located on the left side of the vertical rib 52b and a part located on the right side. The sponge body 4 located on the left side is positioned in a range surrounded by the first rib 51, the upper and lower horizontal ribs 52a and 52a, and the vertical rib 52b. The sponge body 4 positioned on the right side is positioned in a range surrounded by the vertical rib 52b, the upper positioning rib 54a positioned on the right side of the vertical rib 52b, the lower positioning rib 54b, and the right positioning rib 54d. It is like that.
[0026]
The mirror glass 2 is fixed to the housing 1 by fitting the rim 6 into the housing 5. At this time, the liquid crystal monitor 3 is pushed inward to compress and deform the sponge body 4 by a predetermined amount.
[0027]
In the inner mirror 1 configured as described above, the liquid crystal monitor 3 is sandwiched between the housing 5 and the mirror glass 2 by pressing the liquid crystal monitor 3 against the back surface of the mirror glass 2 with an elastic force. Since it is fixed, it is not necessary to fix the liquid crystal monitor 3 using screws. Therefore, since the liquid crystal monitor 3 can be attached in a short time, the number of assembling steps can be reduced.
[0028]
In addition, since the liquid crystal monitor 3 is always in close contact with the back surface of the mirror glass 2, light from the liquid crystal monitor 3 does not leak from between the liquid crystal monitor 3 and the mirror glass 2. Therefore, even when the liquid crystal monitor 3 is displayed, the portion of the mirror glass 2 other than the liquid crystal monitor 3 functions as a rear confirmation mirror. Further, since the liquid crystal monitor 3 and the mirror glass 2 are always in close contact with each other, it is possible to completely prevent vibration noises caused by separation and contact of these members.
[0029]
Further, since the liquid crystal monitor 3 is elastically pressed by the sponge body 4, a wide range of the liquid crystal monitor 3 can be pressed with a constant surface pressure. Therefore, the liquid crystal monitor 3 can be stably held. In addition, since a wide range of the liquid crystal monitor 3 can be pressed, the surface pressure acting on the liquid crystal monitor 3, the housing 5 and the like can be kept low. Therefore, it is possible to improve the durability of the liquid crystal monitor 3, the housing 5, and the like.
[0030]
Furthermore, the rib 50 of the housing 5, for example, the first rib 51, the portion surrounded by the upper and lower horizontal ribs 52a and 52a, and the vertical rib 52b, the vertical rib 52b, the upper positioning rib 54a, and the lower positioning rib Since the sponge body 4 can be positioned at a portion surrounded by the b and the right positioning rib 54d, the sponge body 4 can be reliably held at a predetermined position. That is, it is possible to prevent the sponge body 4 from being displaced due to vibration or the like. In addition, since the rib 50 is formed integrally with the housing 5 and there is no need to provide other parts for positioning the sponge body 4, the number of parts and the cost can be reduced.
[0031]
Further, the liquid crystal monitor 3 can be positioned at predetermined positions in the left and right and up and down directions, that is, in the horizontal direction by the upper positioning rib 54a, the lower positioning rib 54b, the left positioning rib 54c and the right positioning rib 54d. The monitor 3 can be reliably held at a predetermined site in the mirror glass 2.
[0033]
Further, the mirror glass 2 may be configured to open a portion corresponding to the display unit of the liquid crystal monitor 3. In this case, a normal mirror that is not a half mirror can be used as the mirror glass 2.
[0034]
Furthermore, although the example which has arrange | positioned the liquid crystal monitor 3 as a video monitor which image | photographs the back of a vehicle as a monitor inside the mirror glass 2 was shown, for example, it is not limited to such a video monitor, For example to an obstruction An image image such as a monitor for warning of proximity, a monitor for notifying that the vehicle is in the back gear, a monitor for remaining amount of engine oil alarm, a half-door alarm monitor, etc. that have nothing to do with such reverse running A monitor for displaying may be installed in the inner mirror. In this case, it is preferable that the monitor is normally in the mirror glass 2 so that its display cannot be seen and an image is displayed only when an abnormality or the like occurs. Alternatively, a simple light may be used in place of the image and lighted only when an abnormality or the like occurs.
