A rotating window according to an embodiment of the present invention is described below with reference to fig. 1 to 4, and includes:
the guide ring 100, wherein a power piece 110 which rotates around the guide ring 100 is arranged on the inner side of the guide ring 100, a magnetic acceleration module 120 is arranged on the outer side of the guide ring 100, and the magnetic acceleration module 120 is used for accelerating the power piece 110 to pass through by magnetic attraction;
a glass window 200, the glass window 200 being connected to the power member 110 to rotate on the guide ring 100 as the power member 110 moves.
In the rotating window provided by the invention, when the power piece 110 is about to pass through the magnetic acceleration module 120, the magnetic acceleration module 120 generates a magnetic field to attract the power piece 110, so that the power piece 110 is accelerated, and the rotating speed of the glass window 200 is further accelerated; whenever the power member 110 is about to leave the magnetic acceleration module 120, the magnetic acceleration module 120 no longer generates a magnetic field to avoid drag caused by pulling the power member 110. In this way, the power member 110 can continuously obtain acceleration along the rotation process of the guide ring 100, so as to increase the rotation speed of the glass window 200, and ensure that the glass window 200 can throw away the liquid splashed on the surface of the glass window by the centrifugal force of high-speed rotation. According to the rotary window provided by the invention, the glass window is accelerated by the magnetic acceleration module 120, and the glass window 200 is not required to be driven by a high-speed motor to rotate at a high speed, so that the cost of the rotary window can be effectively reduced.
The magnetic acceleration module 120 comprises a first electromagnet 121 and a second electromagnet 122, wherein the first electromagnet 121 and the second electromagnet 122 are positioned on two opposite sides of the guide ring 100 in parallel, when the power piece 110 reaches the first electromagnet 121 and the second electromagnet 122 along the guide ring 100, the first electromagnet 121 and the second electromagnet 122 are electrified to generate a magnetic field, and when the power piece 110 passes out of the first electromagnet 121 and the second electromagnet 122 along the guide ring 100, the first electromagnet 121 and the second electromagnet 122 are in a power-off state.
In this embodiment, when the power member 110 moves along the guide ring 100 to reach the magnetic acceleration module 120, the first electromagnet 121 and the second electromagnet 122 generate a magnetic field in a conductive manner, and attract the power member 110 to accelerate the power member 110. When the power member 110 is about to leave the magnetic acceleration module 120 due to inertia, the first electromagnet 121 and the second electromagnet 122 are powered off to cancel the magnetic field, so as to avoid generating resistance force by attracting the power member 110.

In this embodiment, the energizing ring 130 abuts against the power element 110 to achieve electrical connection, and when the power element 110 moves to the trigger conductive segment 140, the power element 110 contacts with the trigger conductive segment 140 to achieve electrical connection, so that the first electromagnet 121 and the second electromagnet 122 are connected to an external power source, even if the first electromagnet 121 and the second electromagnet 122 generate a magnetic field to attract the power element 110 to achieve acceleration of the power element 110. When the power member 110 leaves the triggering conductive segment 140, the first electromagnet 121 and the second electromagnet 122 are in a power-off state. In this embodiment, the power member 110 directly triggers the first electromagnet 121 and the second electromagnet 122 to be powered on or powered off, so that a sensor is not needed, and the cost of the rotating window can be further effectively reduced.
