Problems solved by technology

[0003] However, the current exercise bikes used indoors usually display the rotation speed of the exercise bike on a monitor. Users can only know their own riding speed, and it is difficult to know the riding status of others.
Moreover, during group training, the coach must check each display one by one to know the riding speed of all students, which is really inconvenient

Abstract

The invention discloses a battery-free rotational speed indication device. The battery-free rotational speed indication device comprises a magnet, an induction coil, a rectification amplifying and driving circuit and an indication device body, wherein the magnet is arranged on a wheel axle of an exercise bicycle; the induction coil is arranged on a wheel of the exercise bicycle, and the wheel is arranged on the wheel axle in a penetrated mode and rotates relative to the wheel axle; the rectification amplifying and driving circuit is arranged on the wheel and electrically connected with the induction coil; the induction device body is arranged on the wheel and electronically connected with the rectification amplifying and driving circuit. When the wheel rotates, the induction coil rotates relative to the magnet, so that a magnetic field changes, and an induction current is generated; the rectification amplifying and driving circuit rectifies the induction current into a direct current and amplifies the direct current so as to drive the induction device body to send out an indication corresponding to the rotational speed of the wheel.

Description

technical field [0001] The invention relates to a rotating speed indicating device, in particular to a rotating speed indicating device without using a battery. Background technique [0002] With the popularity of sports and leisure, various sports equipment such as bicycles, exercise bikes, treadmills and other indoor or outdoor appliances have been widely used by the public. The exercise bike installed indoors allows users to achieve fitness exercise effects in a limited space, allowing users to perform pedaling exercises like riding a bicycle. [0003] However, the current exercise bike used indoors usually uses a monitor to display the rotation speed of the exercise bike. Users can only know their own riding speed, and it is difficult to know other people's riding conditions. Moreover, during group training, the coach must check each display one by one to know the riding speed of all students, which is really inconvenient. Contents of the invention [0004] In view o...
