[0034] First embodiment

[0035] according to Figures 1 to 3 As shown, the utility model provides a roller control module, including: a roller 1, an encoder 2, a first bracket 3, a contact switch 4, and a second bracket 5.

[0036] Specifically, the input end of the encoder 2 is connected to the roller 1; the roller 1 is rotatably connected to the first bracket 3, and a first contact 34 is provided on the first bracket 3; wherein, the first contact 34 can be provided on the lower side of the first bracket 3, and the roller 1 can be provided on the upper side of the first bracket 3; the contact switch 4 is provided with a second contact 41 corresponding to the first contact 34; the contact switch 4 is fixedly arranged relative to the second bracket 5, and the first bracket 3 is rotatably connected to the second bracket 5 to drive the first contact 34 to contact or separate with the second contact 41.

[0037] Through the above-mentioned arrangement, that is, applying downward pressure on the roller 1, the first bracket 3 can be rotated downward relative to the second bracket 5, so that the first contact 34 and the second contact 41 are in contact and conductive, and the contact switch 4 generates a signal. Since the second contact 41 is compressed after the contact and has a recovery potential, when the downward pressure is no longer applied to the roller 1, the first bracket 3 will be subjected to the rebound force of the second contact 41 during the recovery process of the second contact 41 and rotate upward to reset, so that the first contact 34 and the second contact 41 are separated and disconnected, and the contact switch 4 stops generating a signal, thereby realizing the rotating and pressing click operation mode.

Compared with the method of rotating the wheel-shaped roller 1 through the central axis 53, this embodiment can save the space required for rolling the roller 1, so that the roller 1 control module can be set in a smaller electronic device.

The roller 1 is rotatably connected to the first bracket 3 by the first rotating shaft 11 rotatingly fitting in the first rotating hole 31, and the second rotating shaft 12 rotatingly fitting in the second rotating hole 32; accordingly, the second rotating shaft 12 is connected to the input end of the encoder 2, so that the input end of the encoder 2 is connected to the roller 1.

[0041] Furthermore, the roller 1 control module also includes: a flexible circuit board 6, the flexible circuit board 6 is provided with a first input terminal 61 corresponding to the encoder 2, and the output terminal of the encoder 2 is connected to the first input terminal 61. In addition, the flexible circuit board 6 is provided with a second input terminal 62 corresponding to the contact switch 4, and the output terminal of the contact switch 4 is connected to the second input terminal 62.

[0042] Preferably, the first bracket 3 is provided with a snap-on platform 33 corresponding to the first input end 61, the encoder 2 is fixed to the first input end 61, and the first input end 61 is connected to the snap-on platform 33, so that the encoder 2 is fixedly arranged relative to a bracket; more preferably, the second bracket 5 is provided with a connecting platform 54 corresponding to the second input end 62, the contact switch 4 is fixed to the second input end 62, and the second input end 62 is connected to the connecting platform 54, so that the contact switch 4 is fixedly arranged relative to the second bracket 5.

[0043] In practice, the flexible circuit board 6 is also provided with a signal output terminal 63 for outputting signals, so as to output the signals generated by the encoder 2 and the signals generated by the contact switch 4; optionally, the second bracket 5 is also provided with a fixing hole 52, and the fixing hole 52 is used to pass through the fixing part to fix the roller 1 control module in the electronic device.
