Description

  The present invention relates to a structure for fixing a display device with a buffer member.

  As a conventional display device, a display device having an upper case having a window portion, a display device disposed at a position visible from the window portion, and a lower case housing the display device is known.

JP-A-2005-74554

    However, since such a display device has a structure in which the display is fixed to the upper case using only screws and prevents displacement in the vertical direction and the horizontal direction, a high pressure is applied to the place to be screwed. There was a problem that the upper case would be distorted.

Accordingly, the present invention provides a front panel having a window portion, an upper case in which the front panel is incorporated, a display device disposed at a position visually recognized from the window portion, and a circuit board on which the display device is disposed. A lower case in which the circuit board is stored,
The upper case includes a protruding portion protruding toward the indicator,
The indicator has a buffer member interposed between the protrusion and the display.

  According to the present invention, the buffer member is a flat member having a contact surface that contacts the edge of the display, and the contact surface presses the edge in the vertical direction and the horizontal direction. is there.

  In the present invention, the protrusion has a recess in which a surface of the buffer member facing the abutting surface is attached.

  ADVANTAGE OF THE INVENTION According to this invention, even if it is a case where it is a case where it is a case where it is a case where it is used in the working environment accompanied with a vibration, the display apparatus which can prevent the shift | offset | difference to the vertical direction and a horizontal direction of a display can be provided.

1 is a cross-sectional view of a display device showing a first embodiment of the present invention. Sectional drawing of the liquid crystal display of the display apparatus. The enlarged view of the buffer member of the display apparatus.

  Hereinafter, a display device according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

  As the display device according to the present invention, for example, a display device mounted on a vehicle or the like is known. The vehicle display device includes a front panel 1 having a window portion 11, an upper case 2 in which the front panel 1 is incorporated, a liquid crystal display 3 disposed at a position visually recognized from the window portion 11, and a liquid crystal display. Mainly composed of a circuit board 5 on which the device 3 is disposed and a lower case 6 in which the circuit board 5 is accommodated, and the upper case 2 and the lower case 6 are engaged by a hook (not shown) or the like. Yes.

  The front panel 1 is provided with a window 11 such as a light transmissive transparent glass and covers the front side of the liquid crystal display 3.

  The upper case 2 is made of a synthetic resin material, and the front panel is insert-molded. The upper case 2 is integrally formed with a protruding portion 21 that protrudes toward the liquid crystal display 3. The protrusion 21 is formed with a recess 22 in which a buffer member 4 described later is disposed.

  As shown in FIG. 2, the liquid crystal display 3 includes a transmissive liquid crystal display panel 31, a sheet-like diffusion plate 32 disposed behind the liquid crystal display panel 31, and the liquid crystal display panel 31 and the diffusion plate 32. A cell case 33 to be held, a light emitting diode 34 as a light source disposed behind the cell case 33 and illuminating the liquid crystal display panel 31 and the diffusion plate 32 from behind, a circuit (not shown) for driving the liquid crystal display panel 31, and the like Are mounted on the hard circuit board 35 and a metal cell restrainer 36 for fixing the liquid crystal display panel 31 and the cell case 33 to the circuit board 35.

  The cell retainer 36 is formed by pressing a metal plate, continuously covers the peripheral upper surface of the liquid crystal display panel 31, and has a frame-shaped side portion 36 a and an upper portion that extend toward the circuit board 35 along the side wall of the cell case 33. 36b.

In the case of this embodiment, the buffer member 4 is arranged in the concave portion 22 by using a flat sponge material with an adhesive tape or the like. The buffer member 4 is a flat plate member having a contact surface 41 that contacts the edge 361 of the liquid crystal display 3, and is inclined with respect to the edge 361, and the contact surface 41 is the edge 361. Are pushed vertically and horizontally. Thus, since the thickness is constant by making the buffer member 4 into a flat plate shape, it is possible to make the pressure pushed by the protruding portion 21 constant during assembly.

  Moreover, the buffer member 4 is an edge part around the liquid crystal display 3, and is provided on four opposing sides. Each side is preferably arranged without contacting each other. This has the effect of preventing the front panel 1 from being fogged when it is placed in close contact with each other.

  In the present embodiment, the example in which the buffer member 4 is interposed between the cell restraint 36 and the protruding portion 21 has been described. However, even if the cell restraint 36 is not provided, the edge 361 of the liquid crystal display 3 is the cushion member. 4 may be pressed.

  As described above, the display device according to the present invention includes a front panel 1 including the window portion 11, an upper case 2 in which the front panel 1 is incorporated, and a liquid crystal display device 3 disposed at a position visually recognized from the window portion 11. A circuit board 5 on which the liquid crystal display 3 is disposed, and a lower case 6 in which the circuit board 5 is accommodated, and the upper case 2 includes a projecting portion 21 projecting toward the liquid crystal display 3, The display 3 can prevent the liquid crystal display 3 from being displaced in the vertical direction and the horizontal direction because the buffer member 4 is interposed between the display 21 and the protrusion 21.

  In the display device of the present invention, the buffer member 4 is a flat plate member having a contact surface 41 that contacts the edge 36 of the liquid crystal display 3, and the contact surface 41 extends the edge 361 in the vertical direction and By pressing in the horizontal direction, the liquid crystal display 3 can be reliably fixed.

  Further, in the display device according to the present invention, the protrusion 21 has the concave portion 22 where the surface facing the abutting surface 41 of the buffer member 4 contacts, thereby simplifying the process.

  In the present embodiment, since the liquid crystal display 3 is assembled from the state in which the upper case 2 is turned upside down, for example, in the L-shaped buffer member 4, the buffer member 4 is attached to the edge 361 of the liquid crystal display 3. Although the process of fitting was complicated, in this invention, since the edge part 361 of the liquid crystal display 3 should just be arrange | positioned so that it may contact | abut on the surface of the buffer member 4, a process can be simplified further.

  In the present embodiment, it is assumed that the liquid crystal display 3 arranged in the upper case 2 is pressed when the upper case 2 and the lower case 6 are assembled. Even if it is fixed to the upper case 2, the lower case 3, or the middle case with screws, the buffer member 4 can be used to prevent the liquid crystal display 3 from being displaced in the vertical and horizontal directions.
