Abstract

The invention discloses a control circuit of a kettle-bell. The kettle-bell comprises a body, a base and a weight unit. The body comprises a shell and a rotary shaft. The upper end of the rotary shaftis rotatably mounted in an inner cavity of the shell and the lower end of the shell is opened; the balancing weights and the shell are situated above the base, and the shell covers the outer side ofthe weight unit; the base comprises a shell, a motor and a driving shaft, the driving shaft is fixed on the output shaft of the motor, and the driving shaft drives the rotary shaft to rotate by a setangle to select balancing weights; the control circuit comprises a micro-controller, a human-machine interacting circuit, a driving shaft position detection circuit and a motor driving circuit; the input end of the motor driving circuit is connected to a power supply, the output end is connected to the motor, and the control end is connected to the micro-controller; the human-machine interacting circuit and the output end of the driving shaft position detection circuit are connected to the micro-controller. According to the control circuit disclosed by the invention, the weights of the balancing weights are set by means of the human-machine interacting circuit. The micro-controller controls the rotary shaft to rotate at a special angle to select the body to carry the balancing weights according to the set weight, an operation of adjusting the weight is convenient, and the safety property is good.

Description

[technical field] [0001] The present invention relates to kettlebells, in particular to a control circuit for kettlebells. [Background technique] [0002] When using kettlebells for fitness exercises, you can do various exercises such as pushing, lifting, lifting, throwing and squat jumping. The difference between kettlebell training and dumbbell and barbell training is that kettlebells are more effective in improving overall explosive power. Kettlebells are generally made of cast iron. Most kettlebells are all-iron kettlebells with fixed weight. There are 10kg, 15kg, 20kg, 25kg, 30kg, 50kg and other specifications according to the weight. The disadvantage is that the weight is single , unable to satisfy the preferences of different people. A small number of kettlebells add or subtract weight by manually changing the iron handle, which can adjust the weight suitable for the exerciser. But this kind has no electric function, no automatic counting function, can't calculate ...
