Example 1

With reference to fig. 1-12, the present embodiment provides an electric exercise wheel, comprising: the roller wheel 1 is provided with a shell 2, a power supply 3, a driving motor 4 and a controller 5 are arranged in the shell 2, the driving motor 4 is electrically connected with the controller 5, and two induction switches 6 are arranged on the controller 5; the handle comprises a handle A and a handle B, the handle A and the handle B are respectively arranged at two ends of the shell 2, the handle A comprises a movable outer shaft 7 and a fixed inner shaft 8, the movable outer shaft 7 is movably sleeved on the fixed inner shaft 8, a corresponding rotation angle is formed when the movable outer shaft 7 and the fixed inner shaft 8 rotate relatively, the fixed inner shaft 8 is fixedly connected with the driving motor 4, the controller 5 is fixed on the fixed inner shaft 8, two electric coupling adjusting sheets 9 are installed on the movable outer shaft 7, a spring 10 is sleeved outside the electric coupling adjusting sheets 9, the induction switch 6 is arranged corresponding to the electric coupling adjusting sheets 9, the electric coupling adjusting sheets 9 are controlled to trigger the corresponding induction switch 6 on the controller 5 by rotating the movable outer shaft 7 and adjusting the rotation angle, so that the induction switch 6 is switched on, and further controls the forward rotation or reverse rotation of the drive motor 4.

In this embodiment, when the user starts the switch of the power supply 3, when the movable outer shaft 7 of the adjustment handle a rotates clockwise by a corresponding angle relative to the fixed inner shaft 8 (handle B), one of the electrically coupled adjustment tabs 9 triggers the corresponding inductive switch 6 on the controller 5, so that the inductive switch 6 is turned on, and further the controller 5 is triggered to control the driving motor 4 to rotate forward, so that the exercise wheel advances; when the movable outer shaft 7 of the handle A rotates counterclockwise relative to the fixed inner shaft 8 (handle B) by a corresponding angle, the other electric coupling adjusting sheet 9 triggers the corresponding inductive switch 6 on the controller 5, so that the inductive switch 6 is switched on, and the controller 5 is triggered to control the driving motor 4 to rotate reversely, so that the abdomen exercising wheel retreats; when the movable outer shaft 7 of the handle a is not adjusted to rotate (i.e. the rotation angle is zero), because the electric coupling adjusting blade 9 has the spring 10, the electric coupling adjusting blade 9 is in a balanced state under the action of the spring 10, the inductive switch 6 on the controller 5 is not triggered, and the controller 5 cannot be triggered to control the driving motor 4 to rotate.

Example 2

With reference to fig. 1 to 12, compared with the technical solution of embodiment 1, the adjustment range of the rotation angle of the electric abdominal exercise wheel of this embodiment is 3 to 6 degrees. When the rotation angle is less than 3 degrees, the electric coupling adjusting sheet 9 on the movable outer shaft 7 cannot trigger the inductive switch 6 on the controller 5, and further cannot trigger the controller 5 to control the rotation of the driving motor 4; if the rotation angle is larger than 6 degrees, the amplitude of the user's need to rotate the movable outer shaft 7 relative to the fixed inner shaft 8 will be large, especially in the case of user's physical weakness, the user has difficulty in flexibly controlling the exercise wheel due to the large rotation amplitude, thereby causing inconvenience to the user.
