The Z direction shown in FIGS. 1 and 2B is a direction parallel to the operation surface A of the touch panel 2, which will be described later. Let the direction be the negative Z direction.
The terms "perpendicular" and "parallel" do not mean strictly perpendicular or strictly parallel, respectively, but also include substantially perpendicular or substantially parallel.
1, 2A, and 2B show only the support structure 1 of the touch panel, the support structure 1 of the touch panel is provided in an electronic device, for example. The electronic device is, for example, an in-vehicle device such as a car navigation system.

As shown in FIG. 1 , a touch panel support structure 1 comprises a touch panel 2 , a chassis 3 and one or more leaf springs 8 . The touch panel 2 is a flat touch panel having an operation surface A and a back surface B opposite to the operation surface A. As shown in FIG. An operation surface A of the touch panel 2 has a function of displaying an image and a function of detecting a touch by a user's finger or the like. In the touch panel support structure 1, the chassis 3 has an opposing surface E parallel to the back surface B of the touch panel 2 and a supporting surface F parallel to the back surface B, and is arranged such that the opposing surface E faces the back surface B. . The chassis 3 has a recess C for housing a substrate 6, which will be described later, and an end portion D located closer to the touch panel 2 than the bottom of the recess C. As shown in FIG. In the chassis 3 according to Embodiment 1, the recessed portion C of the chassis 3 has a facing surface E and a supporting surface F. As shown in FIG.

A touch panel side sensor 4 , a chassis side sensor 5 , a substrate 6 , and a vibrating section 7 are provided between the touch panel 2 and the chassis 3 . As shown in FIG. 2B, the touch panel side sensor 4 and the chassis side sensor 5 are both flat sensors. The touch panel side sensor 4 is fixed to the rear surface B of the touch panel 2 so that one side of the touch panel side sensor 4 faces one side of the chassis side sensor 5 . The chassis-side sensor 5 is fixed to an end portion D of the chassis 3 so that one surface of the chassis-side sensor 5 faces one surface of the touch panel-side sensor 4 .

Further, the touch panel side sensor 4 and the chassis side sensor 5 are each connected to a substrate 6 fixed to the concave portion C of the chassis 3 . As will be described later, the touch panel 2 is supported on the chassis 3 so as to be displaceable in a direction parallel to the rear surface B and with the rear surface B. As shown in FIG. For example, when the user presses the operation surface A of the touch panel 2 in the negative X direction and the touch panel 2 approaches the chassis 3, the touch panel sensor 4 and the chassis sensor 5 approach each other. and the chassis 3 have approached each other. That is, the touch panel side sensor 4, the chassis side sensor 5, and the substrate 6 have the function of a press determination device that determines whether the operation surface A of the touch panel 2 is pressed. The touch panel side sensor 4 and the chassis side sensor 5 are sensors that detect changes in capacitance, for example. When the distance between the touch panel side sensor 4 and the chassis side sensor 5 changes, each capacitance changes. The substrate 6 determines that the operation surface A of the touch panel 2 has been pressed when the change in capacitance is, for example, equal to or greater than a threshold.

In FIG. 1, four pairs of the touch panel side sensor 4 and the chassis side sensor 5 are shown. Not limited. However, it is preferable that pairs of the touch panel side sensor 4 and the chassis side sensor 5 are evenly arranged on the entire rear surface B of the touch panel 2 so that the pressure applied to the operation surface A of the touch panel 2 can be accurately determined.

The vibrating section 7 is fixed to the rear surface B of the touch panel 2 . The vibrating section 7 is connected to the substrate 6. For example, when the substrate 6 determines that the operation surface A of the touch panel 2 has been pressed, it vibrates in the Y direction to vibrate the touch panel 2 in the Y direction. The vibrating section 7 is preferably arranged near the center of gravity of the touch panel 2 . This makes it easier for the vibrating section 7 to transmit vibrations over the entire touch panel 2 . Although FIG. 1 shows a configuration in which two vibrating units 7 are installed, the number of vibrating units 7 included in the touch panel support structure 1 is not particularly limited. However, when the touch panel support structure 1 includes a plurality of vibrating portions 7 , the plurality of vibrating portions 7 are preferably arranged point-symmetrically with respect to the center of gravity of the touch panel 2 . As a result, uneven vibrations on the touch panel 2 can be suppressed.

Note that, unlike the configuration of the present embodiment, when the vibrating portion 7 vibrates in the X direction to vibrate the touch panel 2 in the X direction, the direction of vibration in the touch panel 2 differs from the propagation direction of the vibration. Vibration unevenness occurs on the operation surface A of the touch panel 2 . On the other hand, when the touch panel 2 is vibrated in the Y direction by vibrating the vibrating section 7 in the Y direction as in the present embodiment, the direction of vibration in the touch panel 2 is the same as the propagation direction of the vibration. This provides an effect that unevenness in vibration is less likely to occur on the operation surface A of the touch panel 2 .

Further, in the present embodiment, when the substrate 6 determines that the operation surface A of the touch panel 2 is pressed, the configuration in which the vibrating section 7 vibrates based on the determination has been described. The configuration is not limited to this configuration. The trigger for vibrating the vibrating section 7 is not particularly limited, and the mode of response when the operation surface A of the touch panel 2 is pressed is also not particularly limited. For example, when the operation surface A of the touch panel 2 is touched with a finger or the like, the vibrating section 7 may vibrate with the fact that the touch panel 2 detects the touch as a trigger. In such an example, even if the operation surface A of the touch panel 2 is pressed and the substrate 6 determines the pressing, the vibrating section 7 may be configured not to vibrate.

The touch panel 2 and the chassis 3 are arranged between the touch panel 2 and the chassis 3 as shown in FIG. , is connected by one or more leaf springs 8 . The leaf spring 8 supports the touch panel 2 with respect to the chassis 3 so as to be displaceable in the Y direction parallel to the back surface B and the X direction perpendicular to the back surface B. As shown in FIG. The configuration of the leaf spring 8 will be described in more detail below. The leaf spring 8 has a first portion 81 , a second portion 82 and a third portion 83 . The first portion 81 has a touch panel mounting surface G parallel to the rear surface B of the touch panel 2 . A touch panel mounting surface G of the first portion 81 is fixed to the back surface B. As shown in FIG. The first portion 81 has a substantially flat plate shape.

The second portion 82 has a chassis mounting surface H parallel to the support surface F of the chassis 3 . A free end of the chassis mounting surface H of the second portion 82 is fixed to the supporting surface F of the chassis 3 . The second portion 82 has a substantially flat plate shape. A portion of the second portion 82 other than the free end portion fixed to the support surface F faces the end portion D of the chassis 3 , and is between the second portion 82 and the end portion D of the chassis 3 . there is a gap.

The third portion 83 extends perpendicular to the touch panel mounting surface G and the chassis mounting surface H and connects the first portion 81 and the second portion 82 . The third portion 83 has a substantially flat plate shape.

The function of the leaf spring 8 will be described below. The second portion 82 of the leaf spring 8 is deformed in the negative X direction through the third portion 83 and the first portion 81 when the operation surface A of the touch panel 2 is pressed in the negative X direction. Then, a positive force in the X direction is applied to the touch panel 2 as a restoring force. Further, when the operation surface A of the touch panel 2 is no longer pressed, the touch panel 2 returns to the initial position due to the restoring force of the second portion 82 . The initial position is a position relative to the chassis 3 when the operation surface A of the touch panel 2 is not pressed.

On the other hand, when the touch panel 2 vibrates in the Y direction due to the vibration of the vibrating portion 7, the third portion 83 gives the vibrating touch panel 2 a restoring force in the direction opposite to the direction of displacement via the first portion 81. . More specifically, when the touch panel 2 vibrates in the Y direction due to the vibration of the vibrating portion 7 and is displaced in the positive Y direction during the vibration, the third portion 83 deforms in the positive Y direction and has a restoring force. gives the touch panel 2 a negative force in the Y direction. Further, when the touch panel 2 vibrates in the Y direction due to the vibration of the vibrating portion 7 and is displaced in the negative Y direction during the vibration, the third portion 83 deforms in the negative Y direction and acts as a positive restoring force. A force in the Y direction is applied to the touch panel 2 .

Even if the third portion 83 is deformed in the positive Y direction or the negative Y direction by the vibration of the vibrating portion 7 as described above, the second portion 82 is not substantially deformed. Therefore, the vibrating section 7 vibrates the entire touch panel 2 in the Y direction while the restoring force in the Y direction is applied by the third portion 83 . In this embodiment, the touch panel 2 is vibrated in the Y direction by the vibrating portion 7, but the touch panel 2 may vibrate in a direction parallel to the rear surface B of the touch panel 2. It may vibrate in a direction parallel to the back surface B (hereinafter simply referred to as "another direction"). In that case, the third portion 83 is configured to have a surface whose normal direction is parallel to the other direction, and gives the touch panel 2 a restoring force in the other direction.

As described above, in the present embodiment, the configuration in which the touch panel 2 is a flat touch panel having the operation surface A and the back surface B opposite to the operation surface A has been described. It may be a touch panel. However, even in that case, the vibrating section 7 is installed on the rear surface B of the touch panel 2 so as to vibrate in the Y direction. In that case, since the leaf spring 8 supports the touch panel 2 so as to be displaceable in the Y direction with respect to the chassis 3, each mounting surface of the touch panel 2 and the first portion 81 of the leaf spring 8 is aligned with the YZ plane. parallel. In addition, when the touch panel 2 is a curved touch panel, the above-mentioned "opposing surface E parallel to the back surface B of the touch panel 2", "direction parallel to the back surface B of the touch panel 2", and "touch panel parallel to the back surface B of the touch panel 2" The meaning of "parallel to the rear surface B of the touch panel 2" in the description "mounting surface G" is "parallel to the planar portion of the rear surface B of the touch panel 2" or "the first portion 81 of the leaf spring 8 on the rear surface B of the touch panel 2. It means "parallel to the mounting surface of the

Next, specific examples of the leaf spring 8 will be described with reference to the drawings. 3A, 3B, and 3C are perspective views showing specific examples of the leaf spring 8 according to Embodiment 1, respectively. The leaf spring shown in FIG. 3A is the leaf spring 8 described above and has a substantially Z-shaped configuration. More specifically, the first portion 81 of the leaf spring 8 is arranged on one surface side of the third portion 83 with the third portion 83 as a reference, and the second portion 82 is located on the third portion. With 83 as a reference, it is arranged on the other surface side of the third portion 83 .

In another example, the leaf spring 9 shown in FIG. 3B has a generally U-shaped configuration. More specifically, the first portion 91 and the second portion 92 of the plate spring 9 are arranged on one side of the third portion with the third portion 93 as a reference. With this arrangement, the first portion 91 and the second portion 92 are arranged to face each other. When the substantially U-shaped leaf spring 9 is applied to the touch panel support structure 1 , the substantially U-shaped leaf spring 9 requires a smaller installation space than the substantially Z-shaped leaf spring 8 . A product with the support structure 1 can be made smaller.

In another example, the leaf spring 10 shown in FIG. 3C, like the leaf spring 8, has a generally Z-shaped configuration. More specifically, the first portion 101 of the leaf spring 10 is arranged on one side of the third portion 103 with the third portion 103 as a reference, and the second portion 102 is located on the third portion. With 103 as a reference, it is arranged on the other surface side of the third portion 103 . Further, the leaf spring 10 has a slit I in the second portion 102 as a difference from the leaf springs 8 and 9 . As described above, the leaf spring 10 has the slit I in the second portion 102 , so that the cross-sectional area of the second portion 102 is reduced compared to the leaf spring 8 or the leaf spring 9 . Section modulus is reduced. When the support structure 1 of the touch panel includes the leaf spring 10 , the restoring force in the positive X direction associated with the deformation in the negative X direction in the second portion 102 is also reduced compared to when the slit I is not provided. That is, for example, when the user presses the operation surface A of the touch panel 2, the reaction force acting on the user is reduced. By adjusting the cross-sectional area of the second portion 102 in this way, it is possible to adjust the reaction force against pressing on the operation surface A of the touch panel 2 . Also, in the example, the slit I is provided in the second portion 102, but the slit may be provided in the third portion 103, or the cross-sectional area of the third portion 103 may be adjusted. This makes it possible to adjust the Y-direction reaction force of the third portion 103 with respect to the touch panel 2 vibrated by the vibrating portion 7 .

4A and 4B are diagrams for explaining a state in which the leaf spring 8 shown in FIG. 3A is fixed to the touch panel 2 and the chassis 3, and a state in which the leaf spring 9 shown in FIG. 3B is fixed to the touch panel 2 and the chassis 3. FIG. be. FIG. 4 shows a state in which two types of leaf springs 8 and 9 are fixed, but this is for the sake of simplification of explanation. uses one type of leaf spring. However, this does not preclude the use of two or more types of leaf springs in the touch panel support structure 1 .

When the leaf spring 8 is employed in the touch panel support structure 1, the touch panel mounting surface G of the first portion 81 of the leaf spring 8 is fixed to the back surface B of the touch panel 2, so that the first portion 81 is attached to the touch panel. It is fixed to the back surface B of 2. The second portion 82 is fixed to the support surface F of the chassis 3 by fixing the free end of the chassis mounting surface H of the second portion 82 of the leaf spring 8 to the support surface F of the chassis 3 . .
When the leaf spring 10 is employed in the touch panel support structure 1, the leaf spring 10 is substantially Z-shaped like the leaf spring 8. It is fixed to the touch panel 2 and the chassis 3 .

When the leaf spring 9 is employed in the touch panel support structure 1, the touch panel mounting surface G of the first portion 91 of the leaf spring 9 is fixed to the back surface B of the touch panel 2, so that the first portion 91 is attached to the touch panel. It is fixed to the back surface B of 2. The second portion 92 is fixed to the support surface F of the chassis 3 by fixing the free end portion of the chassis mounting surface H of the second portion 92 of the leaf spring 9 to the support surface F of the chassis 3 . .
The method of fixing the leaf spring 8, the leaf spring 9, or the leaf spring 10 to the touch panel 2 and the chassis 3 is, for example, a method of fixing with screws and nuts, a method of fixing with double-sided tape, or a method of fixing with an adhesive. .

As described above, the support structure 1 of the touch panel according to Embodiment 1 includes the touch panel 2 having the operation surface A and the back surface B located opposite to the operation surface A, and the opposing surface E and the back surface B parallel to the back surface B. and a chassis 3 having a supporting surface F parallel to the rear surface B, and a facing surface E arranged in a direction facing the rear surface B; First portions 81, 91, 91, 91, 91, 91, 91, 91, 91, 91, 91, 91, 81, 91, 81, 91, 81, 81, 81, 91, 81, 91, 91, 81, 91, 81, 91, 81, 91, 81, 81, 91, 81, 81, 81, 81, 91, 81, 81, 91, 81, 81, 81, 81, 81, 81 101, second portions 82, 92, 102 having a chassis mounting surface H parallel to the support surface F, the free ends of the chassis mounting surface H being fixed to the support surface F, a touch panel mounting surface G and the chassis Leaf springs 8, 9, 8, 9, 8, 9, 8, 8, 9, 9, 9, 9, 9, 9, 9, 8, 8, 9, 8, 8, 8, 9, 9, 9, 9, 8, 9, 8, 8, 8, 8, 8, 8 10.

According to the above configuration, it is possible to individually adjust the restoring force according to each of the displacements in the two directions with one type of elastic member. More specifically, by adjusting the cross-sectional area or the like of the second portions 82 of the leaf springs 8, 9, 10, the second portions 82, 92, 102 are changed from deformation in the negative X direction to positive deformation. The restoring force in the X direction can be adjusted. Further, by adjusting the cross-sectional areas of the third portions 83 , 93 , 103 of the leaf springs 8 , 9 , 10 , the Y-axis of the third portions 83 , 93 , 103 with respect to the touch panel 2 vibrated by the vibrating portion 7 can be adjusted. Directional restoring force can be adjusted.

In recent years, from the viewpoint of design, a so-called narrow-framed touch panel, in which the width of the frame surrounding the touch panel is narrow, is sometimes adopted. In a touch panel with a narrow frame, since the width of the frame surrounding the touch panel is narrow, pressure sensors such as the touch panel-side sensor 4 and the chassis-side sensor 5 described above cannot be provided behind the frame. Therefore, it is necessary to provide a pressure sensor behind the touch panel. In that case, conventionally, a horizontal leaf spring is generally provided on the operation surface of the touch panel as a configuration for generating a restoring force against pressing on the operation surface of the touch panel. In addition, in the touch panel configured in this way, when adopting a configuration in which the touch panel is further vibrated in a direction parallel to the operation surface, in addition to the leaf spring horizontal to the operation surface, the A spring or the like that enables vibration in a direction parallel to the operation surface is required as in the input device of . As described above, conventionally, in order to make the touch panel displaceable in two directions, two types of elastic bodies are required, which complicates the structure and increases the number of parts. There is a problem that it leads to an increase in cost. In the case of a touch panel with a narrow frame, an increase in the number of parts, in particular, is an obstacle to downsizing, and is a problem that should be avoided.

On the other hand, in the touch panel support structure 1 according to the first embodiment, one type of plate springs 8, 9, and 10 may be employed as a configuration for displacing the touch panel 2 in two directions. Therefore, in the touch panel support structure 1 according to the first embodiment, the number of parts is small, and the size and cost of the product can be reduced.

According to the above configuration, the plate spring 8 has a substantially Z-shape, and the first portion 81 and the second portion 82 are arranged on different sides of the third portion 83, respectively. The first portion 81 can be easily fixed to the touch panel 2 and the second portion 82 can be easily fixed to the chassis 3 .

In the touch panel support structure 1 according to Embodiment 1, the first portion 81 and the second portion 82 are arranged on one side of the third portion 83 with the third portion 83 as a reference. It is
According to the above configuration, the leaf spring 9 is substantially U-shaped, and requires a smaller installation space than the Z-shaped leaf spring 8, so that the size of the product can be reduced.

In the touch panel support structure 1 according to the first embodiment, the second portion 102 or the third portion 103 has the slit I. As shown in FIG.
According to the above configuration, when the slit I is provided in the second portion 102, the restoring force associated with the deformation of the second portion 102 is reduced compared to when the slit I is not provided. That is, when the user presses the operation surface A of the touch panel 2, the reaction force acting on the user can be reduced. Further, when the slit I is provided in the third portion 103, the restoring force of the third portion 103 with respect to the vibrating touch panel 2 is reduced.
