The electronic device 1 has a design panel 10 and a display component 20 .
The electronic device 1 is, for example, a liquid crystal display module with a touch panel. If the electronic device 1 is a liquid crystal display module with a touch panel, the design panel 10 is fixed to a housing (not shown). Also, the display component 20 is configured to detect being touched.
However, the electronic device 1 according to the present disclosure is not limited to a liquid crystal display module with a touch panel.
The display component 20 has a display surface portion 21 .
For example, if the electronic device 1 is a liquid crystal display module with a touch panel, the display part 20 slides slightly with respect to the design panel 10 when the display part 21 is pressed during touch panel operation.
The display component 20 is, for example, a liquid crystal display module, and the display surface portion 21 is, for example, a cover glass.
The display surface portion 21 has thickness in the depth direction when the surface of the display surface portion 21 (in the direction of the arrow in FIGS. 1 and 2) is viewed. The display surface portion 21 has side surfaces 22 corresponding to the thickness.

The design panel 10 includes a design surface 11 , an opening 12 , an inner wall portion 13 and projections 14 .
The design panel 10 is made of resin, for example.
The design surface 11 is the surface of the design panel 10 and constitutes the design of the electronic device 1 . The design surface 11 is the design surface 11 viewed in the direction of the arrow shown in FIGS. , are arranged around the display surface portion 21 of the display component 20 .
The design surface 11 has a first edge portion 11a, and the back surface of the design panel 10 facing the design surface 11 has a second edge portion 11b.
The first edge portion 11a is an edge portion of the design panel 10 at the boundary between the design surface 11 and the opening 12 .
The second edge portion 11 b is an edge portion on the boundary between the rear surface and the opening 12 in the design panel 10 .
The opening 12 is a portion penetrating from the design surface 11 to the back surface of the design panel 10 .

The inner wall portion 13 connects the design surface 11 and the back surface at the opening 12 of the design panel 10 .
Specifically, the inner wall portion 13 has a first inclined portion 13a and a second inclined portion 13b on a surface connecting the first edge portion 11a and the second edge portion 11b.
The first inclined portion 13a and the second inclined portion 13b each have a draft angle for pulling out each mold when molding the design panel 10 using a mold set in which two molds are combined, for example. It is inclined only by Moreover, as will be described later, the boundary between the first inclined portion 13a and the second inclined portion coincides with a mold mating surface in the mold set.
The first inclined portion 13a is a portion that is inclined in a direction opposite to the direction in which the projecting portion 14 protrudes toward the design surface 11 from the intermediate region between the design surface 11 and the back surface. In other words, the first inclined portion 13a is inclined such that the cross-sectional area of the opening 12 increases from the intermediate region from the first edge portion 11a to the second edge portion 11b toward the first edge portion 11a.
For example, as shown in FIGS. 4B and 4C, the first inclined portion 13a extends from the midpoint between the design surface 11 and the back surface toward the first edge portion 11a on the design surface 11 side. slants in the direction opposite to the direction in which the
The second inclined portion 13b is a portion that is inclined in the direction opposite to the direction in which the projecting portion 14 protrudes from the intermediate region between the design surface 11 and the back surface toward the back surface. In other words, the second inclined portion 13b is inclined such that the cross-sectional area of the opening 12 increases from the intermediate region from the first edge portion 11a to the second edge portion 11b toward the second edge portion 11b.
For example, as shown in FIG. 4C, the second inclined portion 13b extends from the midpoint between the design surface 11 and the back surface toward the second edge portion 11b on the back surface side. Tilt in the opposite direction.

The inner wall portion 13 faces the side surface 22 of the display surface portion 21 in a state in which the surface of the display surface portion 21 of the display component 20 is exposed from the opening 12 of the design panel 10 . As shown in FIG. 1, the inner wall portion 13 has four corners when the shape of the display surface portion 21 viewed from the front (in the direction of the arrow in FIG. 1) is square.

The projecting portion 14 protrudes from the inner wall portion 13 in an intermediate region between the design surface 11 and the back surface of the design panel 10 .
Specifically, as shown in FIGS. 4B and 4C , for example, the protrusion 14 extends from the midpoint between the design surface 11 and the back surface of the design panel 10 to the back surface, and extends to the second slope of the inner wall portion 13 . It protrudes from the portion 13b.
A plurality of protrusions 14 are provided on the inner wall portion 13 . For example, as shown in FIG. 3, the protrusions 14 are provided at four corners of the inner wall portion 13, respectively.
When the display component 20 is assembled so that the surface of the display surface portion 21 is exposed from the opening 12 of the design panel 10 , the plurality of projecting portions 14 support the side surfaces 22 of the display component 20 .

When the electronic device 1 is a liquid crystal display module with a touch panel, the plurality of projections 14 support the side surface of the cover glass on the side surface 22 of the display component 20 .
Further, when the electronic device 1 is a liquid crystal display module with a touch panel, the plurality of projections 14 are formed in a linear shape parallel to the direction in which the side surface 22 moves slightly when the touch panel is operated on the display component 20, or in a display shape. It has a shape that provides point support against the side surface 22 of the component 20 . When the display component 20 is pressed, the electronic device 1 slides while the display component 20 is in linear contact with the protrusion 14 , or slides while making point contact. Thereby, when the display component 20 slides, the electronic device 1 can suppress the generation of abnormal noise compared to the case where the display component 20 is supported by the surface.

Note that the intermediate region from the first edge portion 11a to the second edge portion 11b described above includes the intermediate point from the first edge portion 11a to the second edge portion 11b, and the first edge portion 11a and the second edge portion 11b This range does not include the second edge portion 11b. The boundary between the first inclined portion 13a and the second inclined portion 13b is appropriately set within the range according to the desired design of the electronic device 1 .
Alternatively, the protrusion 14 may have the shape shown in FIG. 5A or 5B. The shape shown in FIG. 5A is a shape in which the second edge portion 11b side of the protrusion 14 is chamfered (for example, a curved surface shape). In this case, the following effects are obtained. That is, when the display component 20 is assembled so that the surface of the display surface portion 21 is exposed from the opening 12 of the design panel 10, the projecting portion 14 guides the display component 20, which facilitates assembly. The shape shown in FIG. 5B is a shape that protrudes halfway from the intermediate region between the design surface 11 and the back surface of the design panel 10 to the back surface with respect to the design surface 11 .
Further, the number of protrusions 14 and the positions at which the protrusions 14 are provided are not limited to those shown in the drawings, and may be set to any number and any position on the inner wall portion 13 as appropriate. For example, a total of eight projections 14 may be provided, two each on the upper, lower, left, and right sides of the inner wall portion 13 .
4B, 4C, 5A and 5B, the boundary between the first inclined portion 13a and the second inclined portion 13b in the inner wall portion 13 and the point where the protrusion 14 starts to protrude coincide with each other. is shown but not limited to. That is, the boundary between the first inclined portion 13a and the second inclined portion 13b in the inner wall portion 13 and the point where the protrusion 14 starts to protrude need not coincide. For example, when the boundary between the first inclined portion 13a and the second inclined portion 13b in the inner wall portion 13 is closer to the first edge than the midpoint between the first edge 11a and the second edge 11b, the protrusion The point at which projection starts at 14 may be closer to the second edge than the midpoint from the first edge 11a to the second edge 11b. Also, the opposite may be true.

When the display component 20 is assembled to the design panel 10 , the display surface portion 21 of the display component 20 enters the opening 12 .
When the design surface 11 is viewed with the display component 20 assembled to the design panel 10, the surface of the display surface portion 21 of the display component 20 is exposed through the opening 12, as shown in FIG. Further, the side surface 22 of the display surface portion 21 of the display component 20 and the inner wall portion 13 of the design panel 10 face each other.
That is, when the design surface 11 of the electronic device 1 is viewed with the display component 20 assembled to the design panel 10, the surface of the display surface portion 21 of the display component 20 is exposed from the opening 12, and the display surface portion of the display component 20 is exposed from the opening 12. 21 and the inner wall portion 13 of the design panel 10 face each other.

Next, effects of the design panel 10 according to the present disclosure will be described.
FIG. 8 is a partially enlarged view of an electronic device in which a display member is attached to the design panel according to the present disclosure.

Reference example design panel 1010 does not partly employ the present disclosure.
The inner wall slope 1013 in the design panel 1010 differs from the first slope 13a and the second slope 13b of the present disclosure in that it has the same slope from the first edge 1011a to the second edge 1011b.
The design panel 10 and the design panel 1010 are compared.
When the design surface 1011 of the design panel 1010 is viewed from the front, the gap α2 between the first edge portion 1011a and the display surface portion 21 is wide and conspicuous.
In design panel 1010, portion β2 of projection 1014 that is visible when design surface 1011 is viewed is large, and the shape of the surface of projection 1014 is conspicuous as shown in FIG. 11A.
Further, the design panel 1010 has a wide interval α2, and outside light easily enters between the first edge portion 1011a and the display surface portion 21 . Therefore, particularly when design surface 1011 is obliquely viewed, part of the side surface of protrusion 1014 (the surface of protrusion 1014 shown in FIG. 11B) is easily visible.

On the other hand, in the design panel 10, when the design surface 11 is viewed from the front, the distance α1 between the first edge portion 11a and the display surface portion 21 of the display component 20 is narrow and inconspicuous.
Further, in the design panel 10, the portion β1 of the protrusion 14 that is visible when the design surface 11 is viewed is small, and the shape of the front of the protrusion 14 is less noticeable as shown in FIG. 9A.
In addition, the design panel 10 has a narrow interval α1, which makes it difficult for external light to enter between the first edge portion 11a and the display surface portion 21, and when the design surface 11 is viewed, the second inclined portion 13b cannot be seen. Therefore, even when the design surface 11 is obliquely viewed, it is difficult to see the side surfaces of the protrusions 14 that protrude from the second inclined portions 13b (the surfaces of the protrusions 14 shown in FIG. 9B).
