A bracket surrounding the display area and a part of the bracket are bent so as to protrude into the display area of the display unit, and a part of the rotary switch is separated from the display area of the display unit and overhangs. And a support portion that supports the wrapping.

  In the display device according to the present invention, the rotary switch includes a rotary encoder that detects the rotation of the rotary switch, and the rotary encoder includes a first gear provided around a rotation axis of the rotary switch, and the first gear. It can be configured by including a second gear meshing perpendicularly to one gear and a detection device that outputs a pulse signal according to the rotation of the second gear.

  According to the present invention, it is possible to effectively obtain a display device that does not hinder the operation feeling without increasing initial costs such as processing costs.

A display panel such as a liquid crystal display panel and a transparent touch panel for detecting a position where the operator touches the display panel.

  The display 3 displays a screen on the display panel and detects a touch operation using a touch panel. The in-vehicle device executes function items set according to the position coordinates of the touch panel corresponding to the screen of the display panel. The in-vehicle device further operates by mechanical operation of the rotary switch 5. In addition, about this kind of display 3, since the known structure known widely conventionally is used, the detailed description is abbreviate | omitted.

(Rotary switch configuration)
In the present embodiment, the display device 1 using a gear mechanism, in particular, a structure in which the display 3 as a display unit and the rotary switch 5 as a mechanical switch are overlapped so as not to contact each other is a characteristic part. .

  As shown in FIGS. 1, 2, and 3, the rotary switch 5 is a switch having a columnar rotation knob 51 for performing a mechanical operation on the in-vehicle device corresponding to the display on the display 3. For example, it is used for performing a mechanical operation of selecting one function item from a plurality of function items displayed in the display area 31 of the display 3 and switching to a desired display. The rotary knob 51 is rotatably supported on the surface of the center cluster 2 via the rotary shaft 52.

  The bracket 4 surrounding the periphery of the display area 31 of the display 3 is made of a rigid metal frame material, and is also used as a magnetic shield that reduces the influence of a disturbance magnetic field. A part of the bracket 4 has a bent piece 41 bent in an inverted L shape so as to protrude into the display area 31 of the display 3.

  The bent piece 41 is configured as a support portion of the rotary switch 5. The rotary knob 51 is supported by the bent piece 41 so as to be opposed to a position away from the display area 31 of the display 3, and a part of the rotary knob 51 and the display area 31 are overlapped at a required distance D. Wrapped structure.

  As shown in FIGS. 3 and 4, the rotary switch 5 includes a rotary encoder 53 that outputs the rotation position information of the rotary knob 51. The rotary encoder 53 includes a gear mechanism including a first gear 54 and a second gear 55.

  A circular first gear 54 having a rotation shaft 52 as a center is formed on the display facing surface of the rotary knob 51. A through hole 21 is formed on the surface of the center cluster 2, and a second gear 55 that meshes perpendicularly with the first gear 54 is rotatably supported by the inner partition wall 22 of the center cluster 2 in the through hole 21. ing. When the rotary switch 5 is rotated, the first gear 54 and the second gear 55 are engaged with each other, whereby the second gear 55 is rotated in conjunction with the first gear 54.

  The rotary encoder 53 according to the illustrated example is a reflective rotary encoder, and is mounted on the reflection pattern 56 formed on the plane portion of the second gear 55 and the substrate 23 connected to the control unit via a wiring and a connection device (not shown). The optical device 57 is provided. In the reflection pattern 56, reflection portions 561 that reflect with a predetermined interval and non-reflection portions 562 that do not reflect are alternately arranged in the circumferential direction. The reflective portion 561 is formed by, for example, mirror finishing by vapor deposition, application of a reflective paint, application of a reflective seal, or the like.

  One optical device 57 is arranged on the internal partition wall 24 facing the flat portion of the second gear 55 in the center cluster 2 via the substrate 23, and a light emitting unit including a light emitting element such as an LED and a condensing lens, for example. 571 and a light receiving element 572 including a light receiving element such as a photosensor and a condensing lens are housed in one package.

  The optical device 57 is adjusted so that the optical paths of the light emitting unit 571 and the light receiving unit 572 are connected to one of the reflection units 561 of the reflection pattern 56. The detection device in which the reflection pattern 56 and the optical device 57 are combined outputs a pulse signal corresponding to the rotation of the second gear 55, whereby the rotation of the rotary switch 5 is detected.

(Effect of embodiment)
According to the display device 1 configured as described above, the display 3 serving as a display unit and the rotary switch 5 serving as a mechanical switch are overlapped so as not to contact each other. In addition, the following effects can be obtained.

  The mounting rigidity of the rotary switch 5 can be ensured without changing the shape of the display 3.

  Since it is not necessary to perforate the display 3, the appearance design can be improved.

  A tactile feedback can be given to the operator with a simple support structure in which the rotary switch 5 is supported by the bent piece 41 of the bracket 4 serving as a magnetic shield surrounding the periphery of the display area 31 of the display 3.

  The optical rotary encoder 53 may be a transmissive type instead of the reflective type, or a magnetic rotary encoder may be used. Further, the encoder may be an encoder that is not in a non-contact type but is read in physical contact.

  Furthermore, it can also be used as an enter switch for selecting and determining a function item on the display 3 by pushing the rotary switch 5.

  Furthermore, the display device 1 according to the present invention may be selected appropriately according to the purpose of use, for example, according to the purpose of use, and is applied to various terminal devices such as game machines and personal computers other than in-vehicle devices. Of course, the initial object of the present invention can be achieved.
