Some embodiments of the invention are described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.

Referring to fig. 1 and 2, an embodiment of the invention provides a multifunctional knob 100. In this embodiment, the multifunctional knob 100 is used to be installed in an automobile to control components such as a radio, an air conditioner, etc., but is not limited thereto, and in other embodiments, the multifunctional knob 100 may also be used to be installed in a washing machine, a microwave oven, etc.

The multifunctional knob 100 includes a magnetic member 10, a touch member 30, a rotating member 50 and a fixing ring 70. The magnetic member 10 is used for fixing in an automobile. The touch control member 30 is used for being fixed in an automobile and is positioned above the magnetic member 10. The touch control 30 is used for recognizing touch and feeding back to the electric control mechanism. The rotating element 50 is movably sleeved on the touch element 30. The rotary member 50 is used to trigger the touch control member 30. The fixing ring 70 is provided on the rotating member 50. The fixing ring 70 is magnetically attracted by the magnetic member 10 to fix the rotating member 50. The fixing ring 70 is also used for elastically supporting the rotating member 50 to keep a certain distance from the touch member 30.

In the present embodiment, the magnetic member 10 is substantially annular, but is not limited thereto.

Referring to fig. 2, 4 and 5, the touch control 30 includes a button 32 and a circuit pattern 34 disposed in the button. The button 32 is made of a conductive film, such as a transparent conductive optical-grade polyester film mainly made of gold or silver. The button 32 is touched to change the capacitance. The corresponding position of the line pattern 34 senses a touch.

The button 32 includes a first bottom wall 321, a first side wall 323, and a top wall 325. The first bottom wall 321 is substantially annular. The first side wall 323 is disposed around the inner side of the first bottom wall 321. The top wall 325 is connected to an end of the first side wall 323 away from the first bottom wall 321. The top wall 325 forms a stepped structure with the first bottom wall 321. The top wall 325 includes a convex portion 3251 at a central position thereof and a concave portion 3252 surrounding the convex portion 3251.

The circuit pattern 34 includes a first touch sensing area 341, a second touch sensing area 343, a third touch sensing area 345, and a fourth touch sensing area (not shown). The first touch sensing region 341 is aligned with the protruding portion 3251 for sensing whether the protruding portion 3251 is touched. The second touch sensing region 343 is aligned with the concave portion 3252 for sensing whether the concave portion 3252 is touched. The third touch sensing area 345 is aligned with the first bottom wall 321 for sensing whether the first bottom wall 321 is touched. The fourth touch sensing area is aligned with the first sidewall 323 to sense whether the first sidewall 323 is touched.

In the present embodiment, the convex portion 3251 is used for a determination function after being touched. In the present embodiment, the recess 3252, the first bottom wall 321 and the first side wall 323 are used for adjusting the volume by sliding with a finger, sliding a menu, and the like.

Referring to fig. 1 and fig. 2, the rotating element 50 is movably sleeved on the touch element 30. The rotating member 50 includes a second bottom wall 51 and a second side wall 53. The second bottom wall 51 is substantially annular. The second side wall 53 is disposed around the inner side of the second bottom wall 51.

The swivel 50 is exposed from the top wall 325 for ease of handling. The first side wall 323 can be manipulated by separating the rotating member 50.

Referring to fig. 3, a sensing element 55 is attached to a side of the second bottom wall 51 facing the first bottom wall 321. In this embodiment, the sensing element 55 is a conductive patch, but is not limited thereto, and in other embodiments, the sensing element 55 may be another conductive body. The sensing member 55 is used to touch the first bottom wall 321 instead of a finger.

Referring to fig. 2 to 4, the fixing ring 70 is substantially annular and is disposed on a side of the second bottom wall 51 facing the first bottom wall 321. The fixing ring 70 is provided with a relief hole 72. The avoiding hole 72 is used for avoiding the sensing piece 55, so that the sensing piece can be attached to the first bottom wall 321.

In this embodiment, the fixing ring 70 is adhered to the second bottom wall 51 by glue.

The side of the fixing ring 70 facing the second bottom wall 51 is provided with at least one magnetized member 74. The magnetic receiving member 74 is magnetically attracted by the magnetic member 10 to fix the rotary member 50. When the rotating member 50 needs to be separated, a separating force larger than the attraction force of the magnetic member 10 is applied to the rotating member 50.

In this embodiment, the fixing ring 70 is provided with a plurality of elastic sheets 76. A plurality of supporting blocks 57 are disposed on one side of the second bottom wall 51 facing the first bottom wall 321. The elastic pieces 76 elastically support the supporting blocks 57 so that the sensing element 55 is spaced apart from the first bottom wall 321. In use, the rotating member 50 is slightly pressed to make the sensing member 55 contact with the first bottom wall 321, and then rotated.

The fixing ring 70 is made of a non-conductive material such as plastic to avoid interference with the third touch sensing area 345. The rotating member 50 may be made of a conductor such as metal due to the isolation of the fixing ring 70, and of course, the rotating member 50 may also be made of a non-conductive material such as plastic.

In this embodiment, the second sidewall 53 is provided with an anti-slip band 531. The anti-slip band 531 is provided with a plurality of protrusions arranged at intervals to increase friction.

The multifunctional knob 100 of the present invention, when in use: when a menu needs to be slid or the volume needs to be changed, the rotating member 50 is pressed, and the sensing member 55 is made to contact the first bottom wall 321; the depression 3252 can also be touched by finger sliding; the first sidewall 323 can be slid and touched by a finger after the rotary member 50 is separated. After the first bottom wall 321, the concave portion 3252 and the first side wall 323 are touched, the capacitance of the corresponding position changes, and the third touch sensing area 345, the second touch sensing area 343 and the fourth touch sensing area identify the touched position. After the operation is completed, touching the protrusion portion 3251 makes the first touch sensing region 341 sense the capacitance change for confirmation.

It is understood that in other embodiments, the magnetic element 10 and the fixing ring 70 may be omitted, the rotating element 50 may be directly sleeved on the touch element 30 and fixed by gravity, and the touch element 30 provides a certain damping force, so that the rotating element 50 cannot easily rotate to cause a malfunction.

It is understood that, in other embodiments, the elastic sheet 76 and the supporting block 57 may be omitted, and the sensing element 55 directly contacts the first bottom wall 321.

It is understood that in other embodiments, the fourth touch sensing area may be omitted.

It is understood that in other embodiments, the anti-slip band 531 may be omitted.

It is understood that in other embodiments, the protrusion portion 3251, the recess portion 3252, the first bottom wall 321 and the first side wall 323 can be used for other functions according to design requirements.

The touch member 30 of the multifunctional knob 100 of the present invention has a first touch sensing area 341, a second touch sensing area 343, and a third touch sensing area 345 for sensing the touch of a plurality of areas. The first touch sensing area 341 and the second touch sensing area 343 are used for recognizing the touch of a finger. The rotating member 50 can trigger the third touch sensing area 345 to complete the rotation operation of the conventional mechanical knob. The multifunctional knob 100 of the present invention combines a mechanical knob and a touch button, and integrates more functions in a smaller space.

Although the present invention has been described with reference to the above preferred embodiments, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
