Abstract

The utility model relates to a luminous top. The structure is that the magnetic iron and a pair of permanent magnets are embedded on the inner wall of a shell, a coil which can rotate relative to the shell is installed in the center of the shell, an upper cover is arranged above the shell, a light-emitting diode is installed on the upper cover, and two ends of the coil are respectively connected with two poles of the light-emitting diode. When the casing is whipped, the casing and the coil rotate at different speeds, and the coil cuts magnetic lines of force to generate current, so that the light emitting diode emits light. The utility model discloses do not need the battery, can play the function of body-building moreover.

Description

Flash gyro

The utility model relates to a kind of gyro, specifically a kind of gyro of whipping rotation.

Existing luminous gyro generally is that power supply is set in the enclosure, and the top of shell is provided with light-emitting component.It needs consumes energy, needs often to change battery.

The purpose of this utility model be to provide a kind of do not need battery can be luminous gyro.

The purpose of this utility model is achieved in that in the enclosure insert magnetic conduction iron and a pair of permanent magnet on the wall, the center of shell install one can and shell between coil in relative rotation, cover the installation light emitting diode on the shell, the two ends of coil link to each other with the two poles of the earth of light emitting diode respectively.

Advantage of the present utility model is: a pair of permanent magnet of insert and magnetic conduction iron on the inwall of shell, make the inside of shell form a high-intensity magnetic field, the coil that is arranged in the shell is in the magnetic field, when beating the shell of gyro with whip, because can relatively rotate between coil and the shell, shell is different with the velocity of rotation of coil, coil cutting magnetic line and produce electric current, be connected with coil, the light emitting diode that is installed on the outer casing upper cover can send flickering light.That lashes is fast more, and brightness is strong more, can guide the former is ceaselessly whipped a top, and plays the effect of taking exercises.The utility model need not be installed battery, can save and use spending.
