In FIGS. 1 and 2, the side plate 30 is indicated by a two-dot chain line in order to make the drawings easier to see, but in reality, the member indicated by the two-dot chain line is disposed on the front side of the drawing with respect to the member indicated by the solid line. Has been.

Next, an in-vehicle electronic device guide structure for guiding the slider 51 back and forth will be described.
Behind the guide groove 31, the guide rail 40 is fixed to the inner surface of the side plate 30, and the guide rail 40 extends in the front-rear direction. The guide rail 40 is made of a metal material such as galvanized iron, and as shown in FIGS. 3 and 4, the shape of the guide rail 40 having a cross section perpendicular to the front-rear direction is formed in a U shape. Here, FIG. 3 is a perspective view of the on-vehicle electronic device guide structure on the right side of the display panel 20, and FIG. 4 is a cross-sectional view taken along the line IV-IV in FIG.

  A slider 51 extends in the front-rear direction and is inserted into the guide rail 40. When the slider 51 is guided by the guide rail 40, the slider 51 is provided so as to be movable back and forth along the guide rail 40. The slider 51 is moved back and forth together with the panel slider base 50 by a driving mechanism such as a motor.

  A leaf spring 60 as an elastic material is fixed to the side surface of the guide rail 40 by a caulking process 41. The leaf spring 60 is made of a metal material such as stainless steel, and the leaf spring 60 extends forward from the front end of the guide rail 40 and is disposed outside the slider 51. The leaf spring 60 has flexibility so as to bend elastically in the left-right direction depending on its shape, and has rigidity in the up-down direction, and hardly bends in the up-down direction compared to the left-right direction. In front of the front end of the guide rail 40, the upper part of the leaf spring 60 is bent inward along a bending line in the front-rear direction, and a contact piece 61 is formed on the upper part of the leaf spring 60. The contact piece 61 is inclined with respect to a horizontal plane defined by front, rear, left and right, and specifically, is inclined so as to rise from the outside to the inside. The contact piece 61 is in contact with the upper corner of the slider 51. Specifically, the contact piece 51 is in line contact with the upper corner of the slider 51 with a width in the front-rear direction.

Next, the operation of the in-vehicle electronic device 1 will be described.
When the slider 51 and the panel slider base 50 are moved forward by the driving mechanism, the roller 22 is moved downward along the guide groove 31, whereby the display panel 20 is moved backward so that the display screen 21 faces upward. . On the other hand, when the slider 51 and the panel slider base 50 are moved rearward by the drive mechanism, the roller 22 is moved upward along the guide groove 31, and thereby the display panel 20 stands up so that the display screen 21 faces forward. To do.

  The in-vehicle electronic device 1 configured as described above is used by being mounted on a dashboard in a vehicle interior. Therefore, the vehicle-mounted electronic device 1 is vibrated while the vehicle is traveling. Here, since the upper corner of the slider 51 is in contact with the contact piece 61, the upper and lower rattling of the slider 51 can be suppressed, and rattle noise is generated even when the in-vehicle electronic device 1 is vibrated. Can be suppressed. On the other hand, the slider 51 is not pressed down by the abutment piece 61 but is merely received by the abutment piece 61, so that an unnecessary load is not applied to the slider 51. For this reason, when the slider 51 is moved back and forth in order to tilt and stand up the display panel 20, it is possible to suppress an operation load for moving the slider 51 back and forth.

  Further, when the slider 51 is moved back and forth, if the upward vibration load acts on the slider 51 and the load acting on the contact piece 61 from the slider 51 becomes larger than necessary, the leaf spring 60 moves outward. Since it bends, the operation load for moving the slider 51 back and forth can be suppressed.

In addition, since the contact piece 61 is inclined with respect to the horizontal plane, rattling of the slider 51 in the left-right direction can be suppressed.
Further, since the abutting piece 51 is in line contact with the slider 51 with a width in the front-rear direction, it is possible to suppress the rattling of the slider 51 at any position. When the slider 51 is in a position extending forward, it is particularly effective to prevent the slider 51 from rattling by the contact piece 51.

  The present invention is not limited to the above embodiment, and various improvements and design changes may be made without departing from the spirit of the present invention.

  In the above-described embodiment, the contact piece 61 is formed on the upper part of the leaf spring 60. However, when the lower part of the leaf spring 60 is bent inward along the folding line in the front-rear direction, another contact piece becomes a leaf spring. It may be formed in the lower part of 60. When another contact piece is formed in the lower part of the leaf spring 60, the contact piece is inclined with respect to a horizontal plane defined by front, rear, left and right, and specifically, inclined so as to descend from the outside to the inside. The contact piece makes line contact with the lower corner of the slider 51. When the contact piece is formed in the lower part of the leaf spring 60, the upper contact piece 61 may or may not be provided.

Further, the sliding friction between the contact piece 61 and the slider 51 may be reduced by forming a resin on the surface of the contact piece 61 or applying a lubricant to the contact piece 61.
Further, a roller may be attached to the contact piece 61 so as to be able to roll, and the roller may be brought into contact with the upper corner of the slider 51. Similarly, when a contact piece is formed below the leaf spring 60, a roller may be attached to the contact piece.
Alternatively, the upper corner of the slider 51 may be chamfered and the contact piece 61 may be brought into surface contact with the surface. Similarly, when a contact piece is formed below the leaf spring 60, the lower corner of the slider 51 may be chamfered and the contact piece may be brought into surface contact with the surface.

  In the above embodiment, the display panel 20 has been described as an example of the front panel. However, a lid panel that covers the front surface of the electronic device main body may be used as the front panel.
