Signal triggering device of bicycle supporting sensing structure

The utility model discloses a signal triggering device of a bicycle supporting sensing structure, which comprises a sensing seat arranged at a parking point on the ground and a supporting leg arranged on a bicycle, a chip is arranged in the sensing seat, a chip reader is arranged on the supporting leg and is electrically connected to a controller, the bicycle is provided with the signal triggering device, and the signal triggering device is electrically connected to the controller. The signal triggering device is triggered according to the state of the supporting leg, and when the supporting leg is converted into the supporting state from the folded state, the signal triggering device is triggered and starts the chip reader to read chip data. According to the utility model, the signal triggering device is arranged on the supporting leg, and the on-off of a circuit between the chip reader and the controller on the supporting leg is controlled through the signal triggering device, so that the consumption of the
