  • the plate surface of the sliding disk facing the rotating disk is provided with a plurality of lower meshing teeth matched with the upper meshing teeth; and the telescopic structure can drive the sliding disk to move closer to the rotating disk, so as to achieve that the lower meshing teeth engages with the upper meshing teeth, thereby preventing the self-rotation of the rotating disk, and then preventing the self-rotation of the rotating shaft 13 , and the telescopic structure can also drive the sliding disk to move away from the rotating disk, so as to achieve that the lower meshing teeth are separated from the upper meshing teeth, the rotating disk can rotate, and then the rotating shaft 13 can rotate.
  • the telescopic structure may be an electric telescopic rod or a lead screw mechanism.
  • the electric control clutch part is an electromagnetic clutch;
  • the electromagnetic clutch comprises a clutch moving part 21 , a clutch fixing part 22 and a clutch fixing shell 23 ; wherein the clutch moving part 21 is fixedly connected to the rotating shaft 13 , the clutch fixing part 22 is fixedly connected to the clutch fixing shell 23 , the base 30 is fixedly connected to the clutch fixing shell 23 , the clutch fixing shell 23 is used to be fixedly connected with a bicycle frame; the clutch fixing shell 23 is provided with a through hole, and the angle chip fixing shell 54 is fixed on the clutch fixing shell 23 , and the magnet 51 is, at the through hole, provided to be opposite to the HALL angle chip 53 , face to face, this structure makes the structure of the handlebar device compact.
  • the electromagnetic clutch when the electromagnetic clutch is energized, the clutch fixing part 22 sucks and locks the clutch moving part 21 , thereby making the rotating shaft 13 fixed relative to the base 30 , the electromagnetic clutch can be used to realize that the rotating shaft 13 can be fixed no matter which angle the rotating shaft 13 rotates to, enabling more convenient use.
  • the clutch fixing shell 23 is fixedly connected with the bicycle frame, and the base 30 is fixedly connected to the clutch fixing shell 23 .
  • the embodiment of the present disclosure further provides an exercise bike, comprising the handlebar device of any one of the above-mentioned technical solutions, and therefore, it has all the beneficial technical effects of the handlebar device, which are not repeated herein.
  • the exercise bike also comprises the bicycle frame, wherein the base 30 is connected with the bicycle frame.
