no. 1 approach

[0038] figure 1 as well as Figure 2A The operation knob device 10 according to the first embodiment of the present invention is shown. The display panel 1 provided with the operation knob device 10 has a touch detection function for detecting a user's operation through a change in electrostatic capacitance, and is mounted on an in-vehicle product such as a navigation device or a center display.

[0039] Such as figure 1 As shown, the operation knob device 10 is disposed in a predetermined operation area of ​​the display panel 1 and protrudes from the display panel 1 toward the vehicle interior. The operating knob device 10 has a ring shape as a whole, and is arranged such that the axis A extends in a direction perpendicular to the display panel 1 . The operation knob device 10 includes one knob (operation unit) 30 , and transmits a pressing operation and a rotation operation of the knob 30 to the display panel 1 .

no. 2 approach

[0102] Figure 10 The operation knob device 10 of the second embodiment is shown. In this second embodiment, instead of Figure 2A The ring member 45 of the illustrated first embodiment differs from the first embodiment in that the film 50 is provided with a wall portion 50 a.

[0103] Such as Figure 11 As shown, the wall part 50a has a cylindrical shape and is provided on the inner periphery of the annular film 50 by deep drawing. refer to Figure 10 The diameter of the wall portion 50 a is set so that the wall portion 50 a protrudes between the hole wall (inner peripheral surface) of the opening portion 26 of the rotary body 25 and the inner wall portion 30 a of the knob 30 . In addition, the protrusion amount of the wall portion 50 a from the main body of the film 50 is a length between the inner peripheral surface of the rotor 25 and the inner wall portion 30 a of the knob 30 . In the inner peripheral part of the film 50 is not provided Figure 4 The adhesive layer ...

no. 3 approach

[0106] Figure 12 The operation knob device 10 of the third embodiment is shown. This third embodiment differs from the first embodiment in that a wall portion 50 b is provided on the outer periphery of the film 50 .

[0107] Such as Figure 13 As shown, the wall portion 50b has a cylindrical shape and is provided on the outer periphery of the film 50 by deep drawing. exist Figure 13 In the example shown above, the adhesive layer 52b for the holder 20 is provided on the outer peripheral portion of the film 50, but this adhesive layer 52b may not be provided. refer to Figure 12 The wall portion 50b protrudes so as to be located outside the holder 20, and is fixed to the outer peripheral surface of the holder 20 by welding.

[0108] In the operation knob device 10 of the third embodiment, the same operations and effects as those of the first embodiment can be obtained. Moreover, since the cylindrical wall part 50b is integrally provided with the film 50, the intrusion of...

Abstract

An operation knob device 10 includes an annular holder 20, an annular rotor 25 arranged in a holding portion 20a so as to allow rotation around an axis A, an annular knob 30 for which relative movement in a direction along the axis A with respect to the rotor 25 is allowed and relative movement in a circumferential direction around the axis A is restricted, a conductive first transmission member 36 arranged so as to move along the axis A in conjunction with the knob 30, a conductive second transmission member 38 attached so as to rotate integrally with the rotor 25, and a film 50 made from resin interposed between the first transmission member 36 and a display panel 1 and between the second transmission member 38 and the display panel 1. Thus, the transitivity of the pressing operation and the rotating operation is improved.

Description

technical field [0001] The present invention relates to operating knob devices. Background technique [0002] For automotive products such as navigation systems and center displays, display panels equipped with capacitive touch detection functions are generally used. When operating an in-vehicle product, it is necessary to touch a finger to a predetermined operation area of ​​a display panel without unevenness, so the user needs to confirm the position of the operation area with eyes. [0003] Patent Document 1 discloses an operation knob device arranged on the surface of a display panel. The operation knob device includes a holder fixed to the display panel, a push-type button, and a rotation-type knob. Since the capacitance of the display panel changes due to the proximity of the transmission member inside the button, the display panel can detect the push operation of the button. The position where the electrostatic capacitance changes is moved by the transmission membe...
