Description

Technical Field

[0001] The present invention relates to a lever switch, a display device including the lever switch, and a vehicle-mounted device. Background Art

[0002] In the prior art, a multi-directional lever switch is known, which includes a plurality of switches, each of which is selectively driven according to the operating direction of the lever. In this regard, JPH07-14475A discloses a lever switch that drives switches disposed on the left and right sides of the lever by using a pusher to push an operating portion disposed at the top end of an inverted T-shaped lever to the left and right. In this type of lever switch, the switches are disposed to be left-right symmetrical with respect to the fulcrum of the lever, so that the lever ratio from the operating portion at the top end of the lever to the left switch and the right switch is equal, and the same operating feel (operating force) can be obtained when the operating portion is pushed to the left or right. Summary of the invention

[0003] In recent years, a so-called narrow frame design in which the width of the outer frame (frame) of a display device is narrowed has become mainstream. In the case where a multi-directional lever switch is provided in a frame having such a narrow frame, according to the structure of the above-mentioned prior art, the switch must be provided at a position on the opposite side of the fulcrum across the lever. Therefore, there is a problem that the installation space cannot be ensured.

[0004] Aspects of the present disclosure are directed to achieving space savings for a lever switch disposed in a bezel of a display device.

[0005] According to one aspect of the present disclosure, there is provided a lever switch, the lever switch comprising:

[0006] an operating lever including an operating portion to which an operating load is to be applied and configured to swing about a rotation axis;

[0007] a first drive lever driven by the operating lever and configured to swing about a first fulcrum to drive a first switch in response to the operating lever being operated in a first direction about the rotation axis; and

[0008] a second drive lever, the second drive lever being driven by the operating lever and configured to swing about a second support shaft to drive a second switch in response to the operating lever being operated in a second direction opposite to the first direction,

[0009] Wherein, when projected onto a plane orthogonal to the rotation axis, the first support shaft and the second support shaft are arranged on the same side with respect to an imaginary straight line passing through the operating portion and the rotation axis and are spaced apart from the imaginary straight line.

[0010] According to an aspect of the present disclosure, space saving of a lever switch can be achieved. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Hereinafter, as an example of an embodiment of the present disclosure, an aspect of applying the present disclosure to a display device provided in a vehicle-mounted device will be described with reference to the accompanying drawings. The embodiments described below are examples for implementing the present disclosure, and the present disclosure is not limited to the aspects described below. For example, the present disclosure can also be applied to a display device provided in a mobile terminal such as a smartphone or a tablet computer.

[0021] (Overall Configuration)

[0022] Figure 1 is a perspective view showing a part of the display device 100 according to the present embodiment. Figure 2is a front view showing a part of the display device 100 . Figure 1 and Figure 2 The lower right portion of the display device 100 is shown. Figure 1 and Figure 2 The lever switch described later is shown in the initial position. Figure 1 The “front-rear direction”, “up-down direction”, and “left-right direction” shown in FIG. 1 are referred to as the “front-rear direction”, “up-down direction”, and “left-right direction” of the display device 100. These directions merely indicate the relative positional relationship between the components of the present embodiment.

[0023] The display device 100 according to the embodiment is installed on a vehicle-mounted device. The vehicle-mounted device including the display device 100 is, for example, a car navigation device that is installed on a vehicle and provides a general car navigation function. Specifically, the vehicle-mounted device is embedded in a dashboard or a dashboard (neither of which is shown) of the vehicle. The vehicle-mounted device receives an operation of a user (mainly a driver), searches for a route from the current position of the vehicle to a destination, and guides the route selected by the user. For example, the vehicle-mounted device includes a control device. The control device is a device that performs processing of a car navigation function in the vehicle-mounted device, and includes various types of hardware (not shown), such as a central processing unit (CPU), a memory, a communication interface, and an input and output interface.

[0024] The display device 100 is a device that performs input and output of various information in a vehicle-mounted device. Figure 1 and Figure 2 As shown, the display device 100 includes a display panel 10 , a frame 20 , and a lever switch 30 .

[0025] (Display Panel)

[0026] The display panel 10 is a substantially rectangular panel that displays various visual information provided from the control device. The display panel 10 is arranged to be orthogonal to the front-rear direction, and a pair of opposite sides are consistent with the up-down direction. For example, the display panel 10 is a liquid crystal panel. The display panel 10 can be configured so that a touch panel capable of receiving a user's operation is superimposed on the front surface or the rear surface of the liquid crystal panel.

[0027] (frame)

[0028] The frame 20 is a frame body assembled into a frame shape surrounding the display panel 10. The frame 20 includes a frame-shaped front panel 201, which is orthogonal to the front-rear direction and surrounds the outer peripheral edge of the display panel 10, and a tubular peripheral wall panel 202, which extends backward from the outer peripheral edge of the front panel. A substantially rectangular opening 20a is formed in the lower frame portion of the front panel 201, and the lever switch 30 is disposed in the opening 20a.

[0029] (Lever switch)

[0030] The lever switch 30 receives an input operation of the user and outputs a signal corresponding to the input operation to the control device. The lever switch 30 is disposed at a lower frame portion of the frame 20. The lever switch 30 includes a plurality of switches and is configured as a multi-directional lever switch capable of selectively driving the switches according to the operation direction of the operating rod.

[0031] Figure 3 is along Figure 2 A cross-sectional view taken along line AA in FIG. Figure 4 is along Figure 2 A cross-sectional view taken along line BB in FIG. Figure 5 is along Figure 2 Cross-sectional view taken along line CC in FIG. Figures 3 to 5 1 shows a cross section which is orthogonal to the left-right direction of the display device 100 and is orthogonal to the rotation axis A10 extending in the left-right direction. Figures 3 to 5 The positional relationship between the components shown corresponds to the positional relationship between the components when the display device 100 is projected onto a plane orthogonal to the rotation axis A10. Figures 3 to 5 Hereinafter, with respect to the rotation direction centered on the rotation axis A10, the rotation direction when the operating lever indicated by reference numeral 2 is tilted downward is referred to as a first direction F1, and the rotation direction when the operating lever 2 is tilted upward (i.e., the direction opposite to the first direction F1) is referred to as a second direction F2.

[0032] like Figures 3 to 5 As shown, the lever switch 30 includes a circuit board 1, an operating rod 2, drive rods 3 and 4 (a first drive rod 3 and a second drive rod 4), push button switches 5 and 6 (a first switch 5 and a second switch 6), a light source 7 and a holder 8.

[0033] Figures 6 to 8 is a rear view of a portion of the display device 100 according to the present embodiment. Figures 6 to 8 The lower right portion of the display device 100 is shown. Figure 6 Only the frame 20 and the operating lever 2 are shown. Figure 7 Only the frame 20, the operating lever 2, and the drive levers 3 and 4 are shown, and Figure 8 Only the frame 20, the operating lever 2, the drive levers 3 and 4 and the holder 8 are shown.

[0034] In the following, reference will be made to Figures 3 to 8 The structure of the lever switch 30 will be described in detail.

[0035] (Circuit Board)

[0036] The circuit board 1 is an insulating board and Figure 3 As shown in the figures, the circuit board 1 is arranged to face the rear side of the front panel 201 of the display panel 10 and the frame 20 at a certain interval in the front-to-back direction. A circuit pattern is formed on the front surface of the circuit board 1. The display panel 10, the frame 20 and the circuit board 1 form a space S1, and the operating lever 2, the driving levers 3 and 4, the push button switches 5 and 6, the light source 7 and the retaining frame 8 are accommodated in the space S1.

[0037] (Push button switch)

[0038] like Figure 3 As shown, the push button switches 5 and 6 are arranged on the circuit board 1 (the front surface of the circuit board 1). The push button switches 5 and 6 are arranged to be spaced apart from each other in the up-down direction and the left-right direction, and the first switch 5 is arranged on the upper side and the right side of the second switch 6. The guide rods 5a and 6a are respectively arranged on the top part of the push button switches 5 and 6. In the initial state, the guide rods 5a and 6a are biased toward the top part side (front side) by the biasing force of the biasing member (not shown) arranged inside to keep the push button switches 5 and 6 in a disconnected or OFF state. Examples of the biasing member include elastic members such as rubber springs. When the guide rods 5a and 6a are pushed toward the circuit board 1 (rear side) against the biasing force of the biasing member by the operation of the operating lever 2 to be described later, the movable contact point (not shown) arranged inside contacts the circuit pattern of the circuit board 1 to close the circuit. Therefore, the push button switches 5 and 6 are turned on. When the push of the guide rods 5a and 6a is released, the guide rods 5a and 6a return to the original position due to the biasing force of the biasing member, and the contact between the movable contact point and the circuit pattern is released. Therefore, the push button switches 5 and 6 are disconnected. The push button switches 5 and 6 can adopt a known structure. The switch according to the present disclosure is not limited to the push button switch, and various types of switches can be used.

[0039] (Operation lever)

[0040] The operating lever 2 is a member that swings (tilts) around the rotation axis A10 by the user's operation. Figure 3As shown in FIG. 1 , the operating lever 2 includes an integrally formed shaft portion 21, an operating arm 22, a first driving arm 23, a second driving arm 24, and a light guide portion 25. Therefore, the shaft portion 21, the operating arm 22, the first driving arm 23, the second driving arm 24, and the light guide portion 25 integrally rotate around the rotation axis A10.

[0041] The shaft portion 21 is a cylindrical portion extending in the left-right direction with the rotation axis A10 as the central axis. Figure 6 As shown, the shaft portion 21 is provided to protrude from both left and right sides of the operating lever 2 and is pivotally supported by the frame 20 so that the operating lever 2 can swing around the rotation axis A10. Figure 3 As shown in FIGS. 1 and 1B , the shaft portion 21 is disposed at a distance from the circuit board 1 in the front-rear direction.

[0042] The operating arm 22 is a portion to be operated by a user. Figure 3 As shown in the figure, the operating arm 22 extends in a radial direction centered on the rotation axis A10, and protrudes to the outside of the space S1 through the opening 20a. In the initial state, the operating arm 22 stands upright along the normal direction of the display panel 10 (in this example, along the front-to-back direction). A knob portion 221 (an example of an "operating portion") for enabling the user to pinch the operating arm 22 with fingers for operation is provided at the top end of the operating arm 22. That is, the knob portion 221 is the portion to which the operating load is applied by the user. In this specification, the user's operation of the operating arm 22 may be referred to as "operating the operating lever 2".

[0043] The first driving arm 23 drives the first driving rod 3. Figure 3 As shown, the first drive arm 23 extends in a radial direction centered on the rotation axis A10 and in a direction different from the direction of the operating arm 22. The first pressing portion 231 is provided at a side end portion of the first drive arm 23 on the first direction F1 side. When the operating lever 2 is operated in the first direction F1, the first pressing portion 231 presses the first drive lever 3 by moving (swinging) in the first direction F1 centered on the rotation axis A10 as the operating lever 2 rotates. The first pressing portion 231 according to the present embodiment is formed as a protruding portion protruding from the side end portion of the first drive arm 23, but the first pressing portion 231 is not limited thereto and may have any shape as long as the first pressing portion 231 can contact and press the first drive lever 3.

[0044] The second driving arm 24 drives the second driving rod 4. Figure 3 As shown in FIG. 1 and FIG. 2 , the second drive arm 24 extends in a radial direction centered on the rotation axis A10 and in a direction different from the directions of the operation arm 22 and the first drive arm 23. Figure 5As shown, the second pressing portion 241 is provided at the side end portion on the second direction F2 side of the second driving arm 24. When the operating lever 2 is operated in the second direction F2, the second pressing portion 241 presses the second driving lever 4 by moving (swinging) in the second direction F2 with the rotation axis A10 as the operating lever 2 rotates. The second pressing portion 241 according to the present embodiment is formed as a protruding portion protruding from the side end portion of the second driving arm 24, but the second pressing portion 241 is not limited thereto. The second pressing portion 241 may have any shape as long as it can contact and press the second driving lever 4.

[0045] like Figure 6 As shown, the operating arm 22, the first driving arm 23, and the second driving arm 24 are arranged at different positions along the axial direction (left and right direction in this example). The first driving arm 23 is arranged on the right side, the second driving arm 24 is arranged on the left side, and the operating arm 22 is arranged between the first driving arm 23 and the second driving arm 24.

[0046] The light guide portion 25 is a portion that guides the light emitted from the light source 7 to the top end surface of the knob portion 221. Figure 4 As shown, the light guide portion 25 according to the present embodiment is formed as a hollow portion extending from the base end of the operating arm 22 (the base on the side opposite to the knob portion 221) to the top portion (knob portion 221). Therefore, light incident on the operating rod 2 from the base end surface of the operating arm 22 is guided to the top surface of the knob portion 221 and emitted from the top surface. The light guide portion 25 is not limited to the hollow space, and can be formed to include an optical member capable of guiding light. The light guide portion according to the present disclosure can be anything that guides light to the front surface of the operating portion, and the light emitting surface is not limited to the top surface of the operating portion.

[0047] (First driving rod)

[0048] The first drive rod 3 is a member driven by the operating rod 2. When the operating rod 2 is operated in the first direction F1 with the rotation axis A10 as the center, the first drive rod 3 drives the first switch 5 by swinging in the second direction F2 with the first support axis A1 as the center, and the first support axis A1 is a rotation axis extending parallel to the rotation axis A10. Figure 3 As shown, the first drive rod 3 includes an integrally formed first shaft portion 31, a first pressure receiving arm 32 and a first pressing arm 33. Therefore, the first shaft portion 31, the first pressure receiving arm 32 and the first pressing arm 33 integrally rotate around the first support axis A1. The first drive rod 3 is arranged at a position corresponding to the first drive arm 23 of the operating lever 2 and the first switch 5 in the left-right direction.

[0049] The first shaft portion 31 is a cylindrical portion extending in the left-right direction with the first support axis A1 as the central axis. Figure 7 As shown, the first shaft portion 31 protrudes to the left and right sides of the first drive rod 3 and is pivotally supported by the frame 20 and the retaining frame 8 so that the first drive rod 3 can swing around the rotation axis A10. Figure 3 As shown, the first shaft portion 31 is provided between the shaft portion 21 of the operating lever 2 and the first switch 5 in the up-down direction.

[0050] The first pressure receiving arm 32 is a portion to be pressed by the first pressing portion 231 of the operating lever 2. The first pressure receiving arm 32 extends in a radial direction centered on the first fulcrum A1. In an initial state, the first pressure receiving arm 32 contacts the first pressing portion 231 of the operating lever 2 from the second direction F2 side.

[0051] The first pressing arm 33 is a part that drives the first switch 5. The first pressing arm 33 extends in a radial direction centered on the first fulcrum A1 and in a direction different from the first pressure receiving arm 32. The first driving portion 331 is provided at the side end portion of the first pressing arm 33 on the second direction F2 side. In the initial state, the first driving portion 331 contacts the guide rod 5a of the first switch 5. When the first driving rod 3 is pressed by the first pressing portion 231, the first driving portion 331 presses the guide rod 5a by moving (swinging) in the second direction F2 centered on the first fulcrum A1 as the first driving rod 3 rotates, and pushes the guide rod 5a toward the circuit board 1. The first driving portion 331 according to the present embodiment is formed as a protruding portion protruding from the side end portion of the first pressing arm 33, but the first driving portion 331 is not limited thereto. The first driving portion 331 may have any shape as long as it can contact and press the first switch 5.

[0052] (Second drive rod)

[0053] The second drive lever 4 is a member driven by the operating lever 2. When the operating lever 2 is operated in the second direction F2 with the rotation axis A10 as the center, the second drive lever 4 drives the second switch 6 by swinging in the first direction F1 with the second support axis A2 as the center, and the second support axis A2 is a rotation axis extending parallel to the rotation axis A10. Figure 5 As shown, the second drive rod 4 includes an integrally formed second shaft portion 41, a second pressure receiving arm 42, and a second pressing arm 43. Therefore, the second shaft portion 41, the second pressure receiving arm 42, and the second pressing arm 43 integrally rotate around the second fulcrum A2. The second drive rod 4 is arranged at a position corresponding to the second drive arm 24 of the operating lever 2 and the second switch 6 in the left-right direction.

[0054] The second shaft portion 41 is a cylindrical portion extending in the left-right direction with the second support axis A2 as the central axis. Figure 7 As shown, the second shaft portion 41 protrudes to the left and right sides of the first drive rod 3 and is pivotally supported by the frame 20 and the retaining frame 8 so that the first drive rod 3 can swing around the rotation axis A10. Figure 5 As shown, the second shaft portion 41 is provided between the shaft portion 21 of the operating lever 2 and the second switch 6 in the up-down direction.

[0055] The second pressure receiving arm 42 is a portion to be pressed by the second pressing portion 241 of the operating lever 2. The second pressure receiving arm 42 extends in a radial direction centered on the second fulcrum A2. In an initial state, the second pressure receiving arm 42 contacts the second pressing portion 241 of the operating lever 2 from the first direction F1 side.

[0056] The second pressing arm 43 is a part that drives the second switch 6. The second pressing arm 43 extends in a radial direction centered on the second fulcrum A2 and in a direction different from the second pressure receiving arm 42. The second driving portion 431 is provided at the side end portion on the first direction F1 side of the second pressing arm 43. In the initial state, the second driving portion 431 contacts the guide rod 6a of the second switch 6. When the second driving rod 4 is pressed by the second pressing portion 241, the second driving portion 431 presses the guide rod 6a by moving (swinging) in the first direction F1 centered on the second fulcrum A2 as the second driving rod 4 rotates, and pushes the guide rod 6a toward the circuit board 1. The second driving portion 431 according to the present embodiment is formed as a protruding portion protruding from the side end portion of the second pressing arm 43, but the second driving portion 431 is not limited thereto, and the second driving portion 431 may have any shape as long as the second driving portion 431 can contact and press the second switch 6.

[0057] (light source)

[0058] The light source 7 is a light emitting diode (LED) light source having a light emitting surface. Figure 4 As shown, the light source 7 is arranged on the circuit board 1 so that the light emitting surface faces forward. The light source 7 is arranged at a position facing the light guide portion 25 in the front-rear direction so that the light guide portion 25 of the operating rod 2 is located on the optical axis of the light source 7. The light source according to the present disclosure is not limited to LEDs and can be implemented by other types of light emitting elements. For example, the light source can be an organic electroluminescent (EL).

[0059] (cage)

[0060] The retaining frame 8 is a member for retaining the first drive rod 3 and the second drive rod 4. Figure 3As shown in FIGS. 1 and 1 , the retaining frame 8 is arranged between the drive rods 3 and 4 and the circuit board 1 in the front-to-back direction, and supports the drive rods 3 and 4 from the rear side by being fixed to the frame 20. The retaining frame 8 includes a main body portion 81, an axis support portion 82, and a tubular portion 83. The main body portion 81 is formed in a plate shape and is arranged in a posture orthogonal to the front-to-back direction. The axis support portion 82 is arranged on the front surface of the main body portion 81, and rotatably supports the first axis portion 31 of the first drive rod 3 and the second axis portion 41 of the second drive rod. The tubular portion 83 is formed in a tubular shape that penetrates the main body portion 81 and extends in the front-to-back direction. As shown in FIGS. Figure 4 As shown, the tubular portion 83 is provided to surround the light source 7. Light emitted from the light source 7 passes through the tubular portion 83, enters the light guide portion 25 of the operating rod 2, and is emitted from the top end surface of the knob portion 221.

[0061] (operate)

[0062] Next, the operation of the lever switch 30 according to the present embodiment will be described. Figures 3 to 5 In the initial state shown, the push button switches 5 and 6 are kept in the OFF state by the biasing force of the biasing member. Figure 3 and Figure 5 As shown, in the initial state, the first pressing portion 231 of the operating lever 2 is in contact with the first pressure receiving arm 32 of the first drive lever 3, and the first drive portion 331 of the first drive lever 3 is in contact with the first switch 5. In the initial state, the second pressing portion 241 of the operating lever 2 is in contact with the second pressure receiving arm 42 of the second drive lever 4, and the second drive portion 431 of the second drive lever 4 is in contact with the second switch 6. Therefore, in the initial state, the operating lever 2 is supported by the reaction force (biasing force of the biasing member) of the push button switches 5 and 6 via the drive levers 3 and 4, and the operating arm 22 is maintained in an upright position.

[0063] First, refer to Figure 3 Describe the switching-on or ON operation of the first switch 5. An operating load is applied by the user to the knob portion 221 of the operating arm 22, so that the operating arm 22 tilts downward from the initial state. The operating rod 2 is operated in the first direction F1 with the rotation axis A10 as the center to resist the reaction force of the first switch 5. Then, the first pressing portion 231 of the first driving arm 23 moves in the first direction F1, so that the first pressure receiving arm 32 of the first driving rod 3 is pressed. Therefore, the first driving rod 3 swings in the second direction F2 with the first support axis A1 as the center. The first driving portion 331 of the first pressing arm 33 moves in the second direction F2 with the first support axis A1 as the center as the first driving rod 3 rotates, so that the guide rod 5a of the first switch 5 is pushed toward the circuit board 1, and the first switch 5 is driven. Therefore, the first switch 5 is turned on.

[0064] Next, we will refer to Figure 5 Describe the ON operation of the second switch 6. An operating load is applied to the knob portion 221 of the operating arm 22 by the user, so that the operating arm 22 tilts upward from the initial state. The operating rod 2 is operated in the second direction F2 with the rotation axis A10 as the center to resist the reaction force of the second switch 6. Then, the second pressing portion 241 of the second driving arm 24 moves in the second direction F2, so that the second pressure receiving arm 42 of the second driving rod 4 is pressed. Therefore, the second driving rod 4 swings in the first direction F1 with the second support axis A2 as the center. The second driving portion 431 of the second pressing arm 43 moves in the first direction F1 with the second support axis A2 as the second driving rod 4 rotates, so that the guide rod 6a of the second switch 6 is pushed toward the circuit board 1, and the second switch 6 is driven. Therefore, the second switch 6 is turned on.

[0065] Next, the disconnection or OFF operation of the button switches 5 and 6 will be described. When the operating load on the knob portion 221 is removed from the state where the first switch 5 or the second switch 6 is turned on, the drive rods 3 and 4 and the operating rod 2 rotate due to the reaction force of the button switches 5 and 6, and the operating rod 2 returns to the upright posture. Therefore, the button switches 5 and 6 are disconnected, and the lever switch 30 is in the initial state.

[0066] As described above, the lever switch 30 can be operated. The vehicle-mounted device including the display device 100 can control the display of the display panel 10 based on the control signal output from the turned-on button switches 5 and 6. For example, the vehicle-mounted device can move an image or a cursor displayed on the display panel 10 according to the tilt direction of the operating lever 2.

[0067] (Position Relationship)

[0068] Next, the positional relationship of each component of the display device 100 according to the present embodiment will be described. Herein, an imaginary straight line passing through the knob portion 221 and the rotation axis A10 when the lever switch 30 is projected onto a plane orthogonal to the rotation axis A10 of the operating lever 2 is represented by Figures 3 to 5 denoted by L1 in the figure. According to the present embodiment, the imaginary straight line L1 extends parallel to the front-to-back direction. In this article, the plane orthogonal to the rotation axis A10 can be divided into two areas with the imaginary straight line L1 as the boundary. In the plane orthogonal to the rotation axis A10, the area above the imaginary straight line L1 is defined as the first area 101, and the area below the imaginary straight line L1 is defined as the second area 102.

[0069] like Figure 3 As shown in FIG. 1 , the first support axis A1 of the first driving lever 3 is located in the first region 101. That is, the first support axis A1 is disposed above the imaginary straight line L1 and is spaced apart from the imaginary straight line L1. Figure 5As shown, the second support axis A2 of the second drive rod 4 is also located in the first area 101. That is, the second support axis A2 is arranged above the imaginary straight line L1 and is separated from the imaginary straight line L1. Therefore, when projected onto a plane orthogonal to the rotation axis A10, the first support axis A1 and the second support axis A2 are arranged on the same side (the upper side in this example) relative to the imaginary straight line L1, and are separated from the imaginary straight line L1. According to this, one of the button switches 5 and 6 (the second switch 6 in this example) can be arranged near the imaginary straight line L1. In addition, compared with the case where the first support axis A1 and the second support axis A2 are arranged on opposite sides of the imaginary straight line L1, the space required for arranging the drive rods 3 and 4 in the direction orthogonal to the imaginary straight line L1 (the up and down direction in this example) within the above-mentioned plane can be reduced. Therefore, according to this embodiment, the space for the lever switch 30 can be saved. As in the present embodiment, the first support axis A1 and the second support axis A2 are disposed on the inner side of the frame 20 (the display panel 10 side) relative to the imaginary straight line L1, so that even in the case of a narrow frame having a narrow width and a limited arrangement space, the lever switch 30 can be disposed with a margin relative to the frame 20. In the present embodiment, the first support axis A1 and the second support axis A2 are coaxially disposed, and the present disclosure is not limited thereto.

[0070] In this article, Figure 3 As shown, it is assumed that the contact point between the first pressing portion 231 of the operating lever 2 and the first pressure receiving arm 32 of the first driving lever 3 in the initial state is defined as the contact point P11, and the contact point between the first driving portion 331 of the first driving lever 3 and the first switch 5 in the initial state is defined as the contact point P12. At this time, in the direction orthogonal to the extension direction of the imaginary straight line L1 (in this example, the up-down direction), the contact point P11 and the contact point P12 are set on opposite sides relative to the first support axis A1. Figure 5 As shown, it is assumed that the contact point between the second pressing portion 241 of the operating rod 2 and the second pressure receiving arm 42 of the second drive rod 4 in the initial state is defined as the contact point P21, and the contact point between the second drive portion 431 of the second drive rod 4 and the second switch 6 in the initial state is defined as the contact point P22. At this time, in the direction orthogonal to the extension direction of the imaginary straight line L1, the contact point P21 and the contact point P22 are arranged on the same side (the lower side in this example) relative to the second support axis A2. As described above, in the lever switch 30 according to the present embodiment, the first drive rod 3 and the second drive rod 4 have different contact point positions with the operating rod 2 and the push button switches 5 and 6. Therefore, the push button switches 5 and 6 can be driven while the first support axis A1 and the second support axis A2 are arranged to be spaced apart from each other on the same side relative to the imaginary straight line L1.

[0071] like Figure 1As shown, when the display device 100 is projected onto a plane orthogonal to the normal direction of the display panel 10, the operating lever 2 is disposed at a position overlapping the frame 20, and the first switch 5 of the button switches 5 and 6 is disposed at a position overlapping the display panel 10. The first switch 5 is disposed at a position overlapping the display panel 10, so that it is not necessary to ensure a space for the first switch 5 in the frame 20, and thus the frame of the frame 20 can be reduced.

[0072] (Leverage Ratio)

[0073] Hereinafter, the lever ratio of the lever switch 30 will be described. The "lever ratio" is also called a leverage ratio, and is generally expressed as a ratio of the distance between the fulcrum and the point of effort to the distance between the fulcrum and the point of action. By changing the lever ratio, the load required for the lever operation can be adjusted. That is, the operational feel (operating force) of the lever operation, such as hardness or softness, can be adjusted. In the present embodiment, by setting the arrangement and size of each lever and each switch so that the lever ratio (total leverage ratio) of the operating lever 2 and the first switch 5 and the lever ratio (total leverage ratio) of the operating lever 2 and the second switch 6 are equal, the same operational feel can be provided in the driving operation of the first switch 5 and the driving operation of the second switch 6. Hereinafter, the details will be described. The expression "the same lever ratio" means that the lever ratio does not need to be exactly the same as long as there is no significant difference in the operational feel, and includes the case where the lever ratio is substantially the same. The expression "the same lever ratio" means that, for example, when one lever ratio is compared with another lever ratio, the difference between the two is 10% or less, and includes the case where the lever ratio is exactly the same (the difference is 0%).

[0074] like Figure 3 As shown, it is assumed that the distance from the top end of the knob portion 221 (to which the operation load is applied) to the rotation axis A10 is represented by A, the distance from the rotation axis A10 to the contact point P11 between the first pressing portion 231 and the first driving rod 3 is represented by B1, the distance from the contact point P11 to the first fulcrum A1 is represented by C1, and the distance from the first fulcrum A1 to the contact point P12 between the first driving portion 331 and the first switch 5 is represented by D1. Figure 5 As shown, it is assumed that the distance from the rotation axis A10 to the contact point P21 between the second pressing portion 241 and the second drive rod 4 is represented by B2, the distance from the contact point P21 to the second support axis A2 is represented by C2, and the distance from the second support axis A2 to the contact point P22 between the second drive portion 431 and the second switch 6 is represented by D2.

[0075] Furthermore, it is assumed that the leverage ratio of the operating lever 2 and the first driving lever 3 is represented by X1, the leverage ratio of the first driving lever 3 and the first switch 5 is represented by Y1, the leverage ratio of the operating lever 2 and the second driving lever 4 is represented by X2, and the leverage ratio of the second driving lever 4 and the second switch 6 is represented by Y2. At this time, each leverage ratio is obtained by the following relational equation.

[0076] X1=A / B1 (Equation (1))

[0077] Y1=C1 / D1 (Equation (2))

[0078] X2=A / B2 (Equation (3))

[0079] Y2=C2 / D2 (Equation (4))

[0080] When the leverage ratio of the operating lever 2 and the first switch 5 is the total leverage ratio Z1, the total leverage ratio Z1 is the product of the leverage ratio X1 of the operating lever 2 and the first driving lever 3 and the leverage ratio Y1 of the first driving lever 3 and the first switch 5. That is, Z1 is obtained by the following relational equation.

[0081] Z1=X1×Y1 (Equation (5))

[0082] Similarly, when the leverage ratio of the operating lever 2 and the second switch 6 is the total leverage ratio Z2, Z2 is obtained by the following relational equation.

[0083] Z2=X2×Y2 (Equation (6))

[0084] As described above, in the present embodiment, the arrangement and size of each lever and each switch are set so that the total leverage ratio Z1 of the operating lever 2 relative to the first switch 5 and the total leverage ratio Z2 of the operating lever 2 relative to the second switch 6 are equal to each other. Specifically, in the present embodiment, (X1×Y1) and (X2×Y2) are equal, and specifically, ((A / B1)×(C1 / D1)) and ((A / B2)×(C2 / D2)) are equal. Therefore, the same operational feeling can be provided for the driving operation of the first switch 5 and the driving operation of the second switch 6.

[0085] There is no particular limitation on the magnitude of the leverage ratio, and from the perspective of providing a suitable operational feel, the total leverage ratio Z1 and the total leverage ratio Z2 are preferably equal to 1. This makes it possible to obtain an operational feel equivalent to that obtained when the switch is directly operated (pressed) without using a lever. The expression "the leverage ratio is equal to 1" means that the leverage ratio does not need to be exactly the same, as long as there is no significant difference in the operational feel obtained when the switch is directly operated, and includes the case where the leverage ratio is substantially equal to 1. The expression "the leverage ratio is substantially equal to 1" means, for example, a leverage ratio of 0.9 or greater and a leverage ratio of 1.1 or less, and includes the case where the leverage ratio is exactly equal to 1. For example, by making (C1 / D1) and 1 / (A / B1) equal, the total leverage ratio Z1 can be made equal to 1. Similarly, by making (C2 / D2) and (1 / (A / B2)) equal, the total leverage ratio Z2 can be made equal to 1, for example. Furthermore, from the perspective of saving (reducing) the space (space S1 ) of the lever switch 30 in the bezel 20 in the extending direction (front-rear direction) of the imaginary straight line L1 , A>B1 and A>B2 are preferred.

[0086] As described above, in the lever switch 30 according to the present embodiment, when projected onto a plane orthogonal to the rotation axis A10 of the operating lever 2, the first fulcrum A1 and the second fulcrum A2 are disposed on the same side with respect to the imaginary straight line L1 passing through the knob portion 221 and the rotation axis A10, and are spaced apart from the imaginary straight line L1. Therefore, space saving of the lever switch 30 can be achieved.

[0087] Furthermore, in the lever switch 30 according to the present embodiment, the total leverage ratio Z1 of the operating lever 2 relative to the first switch 5 and the total leverage ratio Z2 of the operating lever 2 relative to the second switch 6 are made equal to each other, so that the same operational feeling can be provided in the driving operation of the first switch 5 and the driving operation of the second switch 6. Furthermore, by making the total leverage ratio Z1 and the total leverage ratio Z2 equal to 1, a preferred operational feeling can be provided.

[0088] The lever switch 30 according to the present embodiment further includes a holder 8 that holds the drive rods 3 and 4. The holder 8 includes a tubular portion 83 formed to surround the light source 7. The operating rod 2 includes a light guide portion 25 that guides light emitted from the light source 7 and passing through the tubular portion 83 to the front surface of the knob portion 221. Therefore, the visibility and aesthetics of the operating rod 2 can be improved. In addition, by surrounding the light source 7 with the tubular portion 83, the light of the light source 7 can be prevented from leaking to the outside of the display device 100 from outside the light guide portion 25.

[0089] In addition, in the display device 100 including the lever switch 30 according to the present embodiment, when projected onto a plane orthogonal to the normal direction of the display panel 10, the operating lever 2 is disposed at a position overlapping the frame 20, and the first switch 5 is disposed at a position overlapping the display panel 10. Therefore, the frame 20 can be narrowed. From the perspective of narrowing the frame 20, at least one of the first switch 5 and the second switch 6 can be disposed at a position overlapping the display panel 10.
