M419918 V. New description: 100, JLd-M_:i < Λ Second corpse '丨丨年月ΕΓΐΤΓ. 1 ship' ****—i October 25, 100 revised replacement - [New technical field] The present invention relates to a wireless torque monitoring device applied to a rotating machine with a pedal input mechanism, in particular to monitoring the instantaneous wireless transmission of the torque data of the main driving member on the pedal input mechanism by using a radio frequency (RF) component. Device. [Prior Art] According to the so-called "rotary machine with pedal input mechanism", it refers to an appliance having a pedal driving device such as a bicycle, and includes a bicycle, an electric bicycle, a pedal-type sports equipment, and the like. Device. As described in the rotary machine, the common feature is that there is a pedal input mechanism that can be stepped on the input power of the two feet. The pedal input mechanism usually includes a mandrel, a mandrel _ and two a mandrel shell that is worn out on the side, a pair of cranks that are set at 18 degrees apart from the ends of the mandrel and the mandrel, and a pedal that is freely rotated for the user to step on each of the four (four) handle ends. On the mandrel, there is a scale in the secret lake. Among them, the crank-shaft and the transmission member are in a rotating interlocking state. When the user uses the rotating machine as described above, the two legs are stepped on the pedals on both sides, and by the transmission of the crank and the mandrel, the force is outputted to the other rotating member by the transmission member ( Such as self-propelled wheels, or rotating dampers for sports equipment, etc.). In the aforementioned Pu Gu t, the vehicle (4) has the upper vocational student as the driving force 4 mi99l8 ΐϋβτϊο:-^ The torque of the year (Tor-force state, can also represent the force state of the bicycle body; on each rotary machine, As the main reference for the frame and the strength design of each part; on the electric bicycle, it can provide the basis of the motor-assisted power output; on the sports equipment, it can be used to monitor the user's status, set the operation mode, and determine the damping operation. Pour counts, etc. Basically, in terms of hiding wheels,

The torque change monitoring of the board input mechanism is the basic result of the important data of the rotary machine operation. In the prior art, the best indicator of torque is the strain and stress of the instrument structure surface, and the way to obtain local strain information by Straingauge is the most direct.

However, in the above-mentioned various techniques, since the strain gauge as the torque monitoring is disposed on the mandrel, since the right crank is usually directly coupled to the transmission toothed disc, 'when the user steps on the right pedal, the output is transmitted through the right crank. Direct drive to the drive sprocket 'causes the strain gauges placed on the mandrel and the torque value cannot be detected. Only when the user steps on the left pedal will the output be detected by the left crank and the spindle. In other words 5 M419918
