BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is an exploded perspective view of an electronic apparatus 100 according to a first embodiment of the present invention. Here, the electronic device 100 is assumed to be an electronic device mounted on a vehicle.
As shown in the drawing, the electronic device 100 according to the first embodiment of the present invention includes a chassis 40 and an electronic component 41 attached to the chassis 40 (here, only one of a plurality of electronic components is representative). The appearance of the electronic device 100 can be seen from the user, and the panel 1 having the first insertion hole 1a formed therein and can be inserted into the first insertion hole 1a and operated by the user. (Insertion hole protruding part) 2 having an insertion portion 2b having a built-in button 2e, and a second insertion hole 3d into which the insertion portion 2b is inserted, and inserted into the first insertion hole 1a of the panel 1. And a cover member 3 that covers this peripheral portion from the surface side of the panel 1.
[0026]
Next, each component of the electronic apparatus 100 will be described in more detail.
The panel 1 is formed from a thin plate whose surface is decorated using plastic, wood, or the like, and is disposed on the front side of the electronic apparatus 100. The panel 1 has a first rectangular insertion hole 1a into which the insertion portion 2b of the switch 2 can be inserted. The first insertion hole 1a is set to be larger than the outer shape of the insertion portion 2b, so that a gap in the surface direction of the panel 1 is generated therebetween. That is, in the mounting state where the insertion portion 2b of the switch 2 is inserted as shown in FIG. 2, the first insertion hole 1a is formed by the first insertion hole 1a due to variations in molding and mounting of the panel 1 and the switch 2. Even if the position of 1a and the insertion portion 2b is shifted from the original position in the surface direction of the panel 1, the insertion portion 2b is set to a size and a shape that can be inserted into the first insertion hole 1a.
On the other hand, on the back surface of the panel 1, there are formed mounting columns 1b projecting from four positions around the first insertion hole 1a in the direction perpendicular to the surface of the panel 1 and provided with screw holes, respectively. The switch 2 can be mounted using the mounting support 1b.
The panel 1 is fixed to a vehicle body (not shown).
[0027]
The switch 2 has a flat base 2a having four screw holes 2d, and projects toward the panel 1 from a portion of the base 2a surrounded by the screw holes 2d, and has both sides facing the panel 1 It has a prismatic insertion portion 2b formed with a locking projection (locked portion) 2c protruding outward, and a button 2e that is built into the insertion portion 2b to be pushed into and open and close electrical contacts. .
The base 2a of the switch 2 is fixed with screws (not shown) at positions where the screw holes 2d are respectively fitted to the end faces of the mounting columns 1b of the panel 1 and are separated from the panel 1 by a predetermined distance.
When the switch 2 is fixed to the panel 1, as shown in FIG. 2, the insertion portion 2b of the switch 2 is inserted into the first insertion hole 1a of the panel 1 and the second insertion hole 3d of the cover member 3, and The button 2 e protrudes from the first insertion hole 1 a and the second insertion hole 3 d toward the front surface of the panel 1.
[0028]
The cover member 3 includes an outer cover 3a having a second insertion hole 3d formed therein and an outer edge protruding outward from the second insertion hole 3d in the surface direction of the panel 1, and a switch provided on the back surface of the outer cover 3a. And two locking pieces 3b vertically protruding toward the second base 2a.
The second insertion hole 3d is set so that this size is slightly larger than the insertion portion 2b of the switch 2. The outer cover portion 3a is set to have a size that can extend to the outside of the peripheral portion of the first insertion hole 1a and cover this portion when the cover member 3 is locked by the switch 2. The outer cover 3a functions so that the back surface contacts the surface of the panel 1 to prevent the cover member 3 from moving toward the back surface of the panel 1. It has both functions of the unit.
[0029]
The two locking pieces 3b have a plurality of locking projections (second locking portions) 3c protruding inward at their distal ends so as to face each other and arranged along the extension direction of the locking pieces 3b. It is formed as follows. Here, the locking projections 3c and the locking projections 2c of the switch 2 have a shape having a slope that can be locked. That is, when the cover member 3 and the switch 2 move relative to each other in a direction in which the cover member 3 and the switch 2 approach each other, the locking force between the cover member 3 and the switch 2 is weak and the relative movement is easy. The shape is set to have a degree of inclination, a direction of inclination, and the like so that the locking force between the two becomes strong and cannot be moved with normal external force.
[0030]
FIG. 2 is an enlarged cross-sectional view showing a state where a cover member 3 is attached between the panel 1 and the switch 2 of the electronic apparatus 100. FIG. 2 shows a case in which the switch 2 is attached to the first insertion hole 1a of the panel 1 so as to be displaced to the left from the original position in the drawing, and is drawn from a viewpoint viewed from below in FIG. is there.
As can be seen from this figure, in order to assemble the switch 2 and the cover member 3 on the panel 1, first, the insertion portion 2b of the switch 2 is inserted into the first insertion hole 1a of the panel 1 from the back side of the panel 1, In this state, the base 2a of the switch 2 is fixed to the panel 1. As a result, a gap is formed between the peripheral wall 1c of the first insertion hole 1a of the panel 1 and the insertion portion 2b of the switch 2.
[0031]
Next, after positioning the cover member 3 with respect to the switch 2 so that the insertion portion 2b of the switch 2 enters the second insertion hole 3d of the cover member 3, the locking piece 3b of the cover member 3 is moved from the front side of the panel 1. It is inserted into the space and moved toward the back side. Then, the locking projections 3c of the two locking pieces 3b provided on the cover member 3 sequentially advance over the locking projections 2c of the switch 2 from the locking projections on the tip side thereof. Then, the movement of the cover member 3 is stopped at a position where the outer cover portion 3a of the cover member 3 abuts on the surface of the panel 1 and is locked. This state is the state shown in FIG. 2, and the locking projection 3c and the locking projection 2c are finally locked at this stop position so as to prevent the cover member 3 from coming out of the first insertion hole 1a. become.
[0032]
In this state, the outer cover portion 3a is locked by abutting on the surface of the panel 1, and the locking projection 3c is locked by the locking projection 2c of the switch 2. Therefore, the cover member 3 is connected to the panel 1 and the switch. 2 is positioned. At this time, since the switch 2 is mounted at a position shifted leftward in FIG. 2 from the center of the first insertion hole 1a of the panel 1 due to variations in molding and mounting, the cover member 1 is also mounted on the first side of the panel 1. It will be shifted to the left from the center of the insertion hole 1a. As a result, a first adjustment gap 61 on the left side in the figure is generated between the locking piece 3b on the left side in the figure of the cover member 3 and the left peripheral wall 1c of the first insertion hole 1a in the panel 1 in the figure, and the cover member 3, a right adjustment first gap 62, which is larger than the left first adjustment gap 61, is provided between the right locking wall 3c of the panel 1 and the first insertion hole 1a of the panel 1. Occurs.
The first adjustment gap 61 on the left side and the one adjustment gap 62 on the right side generated for misalignment adjustment as described above are used as a result of the cover member 3 being covered by the outer cover portion 3a from the front side of the panel 1. Become invisible to others. Since the gap between the peripheral wall of the second insertion hole 3d of the cover member 3 and the insertion portion 2b of the switch 2 is previously set to be small, even if there is a variation in molding or mounting, the user is not allowed to. It does not become a size to be worried about.
[0033]
As described above, in the electronic device 100 according to the first embodiment of the present invention, the first insertion hole 1a of the panel 1 is formed between the left first adjustment gap 61 and the right first adjustment gap 62. Since the switch 2 is set to be larger than the locking piece 3b of the cover member 3 inserted into the first insertion hole 1a, the switch 2 is mounted on the panel 1 at a position shifted from the original position in the surface direction of the panel 1. In addition, the switch 2 can be inserted into the first insertion hole 1a of the panel 1 and the cover member 3 can also be inserted into a gap formed therebetween, and in this case, the locking is performed by the outer cover portion 3a. The left first adjustment gap 61 and the right first adjustment gap 62 formed between the piece 3b and the peripheral wall 1c of the first insertion hole 1a of the panel 1 can be covered from the front side of the panel 1. Become. As a result, the adjustment gap between the switch and the panel is invisible to the user, and the appearance is improved.
[0034]
Further, since the outer cover member 3a is made to contact the surface of the panel 1, it is possible to prevent dust and the like from entering the inside of the electronic apparatus 100 from the first adjustment gaps 61 and 62 on the left and right sides. This allows the outer cover portion 3a to also serve as the first locking portion for locking the panel 1 to the panel 1.
Further, a plurality of locking projections 3c of the cover member 3 are provided in the thickness direction of the panel 1, and a locking projection 3c selected from these can be locked to the engaging projection 2c of the switch 2. Since the force hardly changes, even when the switch 2 and the panel 1 are mounted so as to be shifted in the thickness direction of the panel 1, the cover member 3 can be securely locked to the panel 1 and the switch 2. .
