[0028] figure 1 The shown operation input device 100 according to the first embodiment of the present invention is mounted on a vehicle, and is connected to a display in the vehicle compartment, such as a navigation device 20 or a head-up display device (headup display) 120 (see figure 2 ) and the like together constitute the display system 10. Operation input device 100 such as figure 2 As shown, it is provided at a position adjacent to the palm rest 19 in the center console of the vehicle, so that the operation knob 73 is exposed in a range where the operator's hand can easily reach. When an operation force is input by the operator's hand H or the like, the operation knob 73 is displaced in the direction of the input operation force.

[0029] The navigation device 20 is installed in the dashboard of the vehicle, and the display screen 22 is exposed toward the driver's seat. Displayed on the display screen 22 are a plurality of icons associated with predetermined functio...

[0065] Figure 9 ~ Figure 13 The illustrated second embodiment of the invention is a modification of the first embodiment. The reaction force generator 239 of the operation input device 200 of the second embodiment is composed of a first VCM 239x and a second VCM 239y, a magnetic circuit forming body 266 including a movable yoke 251 and two fixed yokes 271 and 272 , and the like. The first VCM 239x has a first coil 241 and two magnets 261 , 262 . The second VCM 239y has a second coil 242 and two magnets 263 , 264 .

[0066] Figure 9 ~ Figure 11 The coils 241 and 242 shown correspond to the coils 41 and 42 of the first embodiment (see image 3 )Structure. The respective coils 241 and 242 form storage chambers 241a and 242a, upper coil side surfaces 241u and 242u, and lower coil side surfaces 241d and 242d, respectively, as in the first embodiment. Each magnet 261-264 and the movable yoke part 251 are accommodated in each storage chamber 241a, 242a. The respective upper c...

[0078] Figure 14 , Figure 15 The illustrated third embodiment of the present invention is another modified example of the first embodiment. In the reaction force generation unit 339 of the operation input device 300 of the third embodiment, the first coil 41 and the second coil 42 can move together with the movable unit 70 . The reaction force generation part 339 is comprised from the 1st VCM39x, the 2nd VCM39y, and the magnetic circuit forming body 366 which includes the movable yoke part 351 and the two fixed yoke parts 371 and 372, etc.

[0079] The movable yoke 351 is the same as the movable yoke 251 of the second embodiment (see Figure 9 ) are similarly suspended by the knob base 74 in a state separated from the respective coils 41, 42 and the respective fixed yoke portions 371, 372. The movable yoke portion 351 is provided with a first coil side yoke portion 352 , a second coil side yoke portion 353 , and a connection portion 354 . The coil side yokes 352 and 353 ...

Abstract

An input device equipped with: an input unit (70); a support unit (50) that supports the input unit such that the input unit is capable of moving; a first actuator (39x, 239x) that causes an operation reaction force (RF_x) in a first direction to act on the input unit; a second actuator (39y, 239y) that causes an operation reaction force (RF_y) in a second direction to act on the input unit; and magnetic path forming bodies (66, 266, 366). The magnetic path forming bodies form a magnetic circuit (65, 265, 365) that guides the magnetic flux generated by first magnetic pole forming parts (61, 62, 261, 262) of the first actuator to a second coil (42, 242) of the second actuator, and guides the magnetic flux generated by second magnetic pole forming parts (63, 64, 263, 264) of the second actuator to a first coil (41, 241) of the first actuator.

Description

technical field [0001] This invention is based on the Japanese application number 2013-268746 for which it applied on December 26, 2013, and uses the description content here. [0002] The present invention relates to an input device for operating force input. Background technique [0003] Patent Document 1 discloses an input device including an operation knob for inputting an operation force, and a main body that supports the operation knob so that the operation knob can be moved by the input of the operation force. The input device also has two voice coil motors. Each of the two voice coil motors has a magnet forming a magnetic pole and a voice coil through which a magnetic flux generated by the magnet passes, and functions as an actuator. In the two voice coil motors, the respective electromagnetic forces generated by the application of current to the respective voice coils act on the operation knob as operation reaction forces in directions perpendicular to each other....
