The invention relates to a semi-passive resistance control system with active reinforcement, which is suitable for sports equipment with a towing assembly.

At present, the rapid development of electronic and electric machinery has also promoted the evolution of sports equipment, indirectly stimulating consumers' functional and personalized needs for sports equipment. Consumers hope to meet their individual needs when using sports equipment. However, today's sports equipment uses a completely passive resistance system that does not provide a fixed output resistance when the user pulls the tow component of the sports equipment, nor does it provide a changeable output resistance compensation during the motion stroke for the user's needs. This cannot be achieved.

In view of the above-mentioned problems of the prior art, one of the objects of the present invention is to provide a semi-passive resistance control system with active reinforcement to solve the conventional completely passive resistance system because it does not have an active adjustment function, and therefore cannot be used at the time of use. Provides a fixed output resistance or an inability to adjust the output resistance during the pulling motion.

In other words, the air pressure supply module includes a pneumatic sensor and a gas storage barrel, and the air pressure sensor and the gas storage barrel are connected to the piston resistance module via a pneumatic pipeline. The air pressure sensor detects the pressure value of the air pressure line, and converts the pressure value into an electrical signal and transmits it to the control module. The pneumatic line is connected to an external air pressure source via a pneumatic source control valve, such as a nitrogen drum or compressed air, and the air pressure source control valve is opened or closed according to the first control command of the control module. The pneumatic line is further connected to the external environment via an exhaust control valve, and the exhaust control valve is opened or closed according to the second control command of the control module. The content of the gas storage barrel is a multiple of the content of the piston resistance module, for example, 9 times.

The air pressure sensor 403 is configured to detect the pressure value of the air pressure line 405, and convert the detected pressure value into the electrical signal 101 and transmit it to the control module 500. The pneumatic line 405 is connected to an external air pressure source 700, such as a nitrogen drum or compressed air, via a pneumatic source control valve 401. The air pressure source control valve 401 is opened or closed according to the first control command 103 of the control module 500.

The position sensor 202 is configured to detect the length of the stroke of the drag component 600, and convert the stroke length into the electrical signal 102 and transmit it to the control module 500. The control module 500 adjusts the power output of the electric motor 201 according to the electrical signal 101 of the air pressure sensor 403 and the electrical signal 102 of the position sensor 202 to provide a suitable adjustment resistance to the coupler 203.

The second reel 2032 is mechanically coupled to the towing assembly 600 to convert the first and second moments into a desired resistance to the towing assembly 600 by coaxial action. The ratio of the radius of the first reel 2031, the third reel 2033, and the second reel 2032 depends on the output resistance of the piston resistance module, the adjustment resistance of the electric motor, and the magnitude and proportion of the expected resistance.

In other words, the control module 500 determines the switching of the air pressure source control valve 401 and the exhaust gas control valve 402 by adjusting the electrical signal 101 of the preset air pressure and air pressure sensor 403 to adjust the gas in and out, so that the air pressure supply module 400 reaches The preset air pressure is preset to generate the preset resistance to the drag component 600.

The length and the second preset mode preselected by the user generate an active adjustment value, and the control module 500 calculates the compensation according to the difference to offset the difference between the output resistance and the preset resistance, and the second preset The active adjustment value specified by the mode calculates the adjustment resistance of the electric motor 201, and the control module 500 controls the electric motor 201 with the third control command 104 to generate the required adjustment resistance.

For example, when the gas pressure is set to about 21 psi, the resistance generated by the air pressure supply module 400 and the piston resistance module 300 is 30 kilograms. Under this condition, the resistance adjustment module 200 can Produces an adjustment resistance of approximately ±30 kg.
