Description

  The present invention relates to an in-vehicle input device used for function selection and function adjustment of, for example, a car air conditioner and a car audio.

  Conventionally, as an example of this type of in-vehicle input device, there has been known a device in which a rotation knob is arranged on a spoke portion of a steering wheel so that a rotation operation on the rotation knob can be detected (see, for example, Patent Document 1). ). An outer case is fixed to the spoke portion, and the rotary knob is disposed in an opening formed in the outer case. Since the rotary knob is often operated by the thumb of the operator who holds the steering wheel, the rotary knob is generally called a thumb wheel, and this rotary knob is integrated at the center of the rotary shaft. The rotating shaft is rotatably supported by a base member covered with an exterior case, and a gear fixed to one end side of the rotating shaft is connected to an encoder. Further, a cam body having a non-circular cross section is fixed to the other end side of the rotating shaft, and an engaging member is elastically brought into contact with the outer peripheral surface of the cam body by a biasing force of a spring.

In the vehicle-mounted input device schematically configured as described above, when the operator holding the steering wheel rotates the rotary knob, the amount of rotation is detected by the encoder, and the cam body is engaged with and disengaged from the engaging member. A feeling arises. Therefore, for example, if the display items on the display screen are sequentially selected based on the output signal of the encoder, the operator can select a desired display item in accordance with the rotation operation of the rotary knob. The selection operation can be recognized by a blind touch with a click feeling.

  By the way, in this type of in-vehicle input device, there is also a demand for a rotary knob called a non-click type that does not cause a click feeling with the rotation operation of the rotary knob. If a click mechanism composed of members is omitted, a non-click type rotary knob can be realized. However, a rotary knob designed as a non-click type cannot be used as a click type, and conversely, a rotary knob designed as a click type cannot be used as a non-click type. When the function adjustment of the car air conditioner is performed with the rotary knob, two types of rotary knobs of a click type and a non-click type have to be arranged.

  The present invention has been made in view of the situation of the prior art as described above, and an object thereof is to provide an in-vehicle input device that can be used for both a click type and a non-click type of one rotary knob. It is in.

  In order to achieve the above object, an in-vehicle input device of the present invention includes a rotary knob rotatably supported on a shaft, a rotation detecting means for detecting the rotation of the rotary knob, and a reciprocatingly supported on the shaft.

The operation key is provided with a drive unit, and the drive unit moves the holding member to the shaft when the operation key is operated. The cam body and the elastic contact body are selectively separated by moving in the axial direction.

  In the vehicle-mounted input device configured as described above, when the rotary knob is rotated while the holding member is in a predetermined position of the shaft and the cam body and the elastic contact body are pressed, the cam body is rotated along with the rotation of the rotary knob. In this case, it can be used as a click-type rotary knob. In addition, if the operating knob is operated to move the holding member in the axial direction of the shaft, and the rotary knob is rotated while the cam body and the elastic contact body are separated from each other, the click feeling is accompanied by the rotation of the rotary knob. In this case, it can be used as a non-click type rotary knob. By operating the operation key arranged in the vicinity of the rotary knob in this way, one rotary knob can be used for both a click type and a non-click type, so the rotary knob can be arranged in a narrow space and the device can be used. The overall size can be reduced.

  In the above configuration, the rotary knob has a support portion supported by the shaft and an internal space continuous to the support portion, and one of the cam body and the elastic contact body is provided on one end surface of the support portion. When the holding member is housed in the internal space, the click mechanism composed of the cam body and the elastic contact body is disposed inside the rotary knob, thereby further reducing the size of the entire apparatus. This is preferable. In this case, a support portion is provided in the center of the inside of the rotary knob, and the support portion is rotatably and swingably supported by the shaft, and swing detection means for detecting the swing of the rotary knob is provided. If equipped, the rotary knob can be operated not only for rotation but also for swinging, so that it can be multifunctional.

  Further, in the above configuration, the operation key arranged in the vicinity of the rotary knob may be a pressing operation type, a slide operation type, or a rotation operation type, but a seesaw operation type operation in which the operation key swings around the shaft. It is preferable to provide a latch means for holding the operation key at the rocking end position in the rocking direction as well as a key because the operability is improved.

  Further, in the above configuration, when one of two different modes is selected by operating the operation key and the function adjustment of the mode selected by the operation key is performed by rotating the rotary knob, for example, a car air conditioner and Of the two different modes of car audio, when the mode of car air conditioner is selected by operating the operation keys, function adjustment such as temperature adjustment can be performed with a click feeling by rotating the rotary knob. When the mode of car audio is selected by the operation, it is possible to perform the function adjustment such as the volume adjustment by rotating the rotary knob without feeling a click.

  Further, in the above configuration, the rotary knob and the operation key may be arranged close to appropriate positions in the vehicle interior such as the console and the dashboard, but these rotary knob and the operation key are arranged close to the spoke portion of the steering wheel. It is preferable that the rotary knob and the operation key can be arranged in a compact manner in the spoke portion where space is limited.

  In the in-vehicle input device of the present invention, a drive unit is provided on an operation key arranged close to the rotary knob, and the drive unit moves the holding member in the axial direction of the shaft by operating the operation key in a predetermined direction. Since the cam body and elastic contact body are selectively separated, one rotary knob can be used for both the click type and non-click type, and the rotary knob can be placed in a narrow space, making the entire device compact. Can be achieved.

Since the switch element 21 pressed by 5e is switched from on to off, the car audio mode is selected based on the switching signal. In this case, the operation key 5 is held in the inclined posture shown in FIG. 4 by the protrusion 17a of the lock plate 17 getting over the mountain portion 5b and engaging with the upper lock groove 5c. Further, the engaging pin 9a moves from the upper end portion to the lower end portion of the drive hole 18 in accordance with the swing operation of the operation key 5, so that the holding member 9 extends along the axial direction of the shaft 3 as shown in FIG. Accordingly, the protrusion 15 c of the first elastic arm 15 a of the elastic contact body 15 is separated from the click groove 16 a of the cam body 16. At that time, since the second elastic arm 15b of the elastic contact body 15 is elastically in contact with the engaging protrusion 13a of the sleeve 13, the return force of the second elastic arm 15b returning to the original posture is utilized. The holding member 9 can be moved smoothly.

  When the operator rotates the rotary knob 4 in the vertical direction in FIG. 1 when selecting the car audio mode, the rotation is detected by the rotation detecting means constituted by the magnet 14 and the magnetic sensor 22. Based on this, the function adjustment for moving the volume of the car audio up and down is performed. At this time, since the cam body 16 that rotates integrally with the rotary knob 4 is separated from the projection 15c of the first elastic arm 15a of the elastic contact body 15, a click feeling is generated when the rotary knob 4 is rotated. The rotary knob 4 is used as a non-click type.
