Abstract

The application discloses a resistance device for wireless control of resistance size of a bicycle training platform, which comprises a magnetic resistance mechanism for generating resistance, an execution mechanism for resistance adjustment, a transmission mechanism, and a plastic support and protection part. The magnetic resistance mechanism comprises aluminum magnetic disk resistance sheets and a magnet. The resistance adjustment execution mechanism is controlled by a motor, and the magnet is dragged to make linear motion relative to the magnetic disk resistance sheets through a screw rod, so that the magnetic flux of the magnet through the magnetic disk resistance sheets is changed. The magnetic disk resistance sheets rotate to cut magnetic force lines, and the resistance acting on the transmission mechanism is correspondingly changed. The motor of the execution mechanism is controlled by an embedded circuit board, and an embedded battery provides power supply for the motor and the circuit board. A remote controller or a mobile phone APP is used to give an instruction to the execution mechanism through signal wireless transmission, so that wireless control of resistance size is realized. The motor execution mechanism is more accurate in action, the resistance values of various gears are more accurate, and a foundation is laid for subsequent intelligent upgrading.

Description

[0002] At present, the magnetic control resistance device for the bicycle training table adjusts the resistance size through an external gear pull line and a switch. The switch is rotated to different gears, and the pull line associated with the switch pulls the magnet to different positions relative to the magnetic disk resistance sheet, changes the size of the magnetic flux passing through the magnetic disk resistance sheet, and the magnetic disk resistance sheet rotates to generate different resistance.
