Induction-type brake-alarming triggering device with self-adaptive structure

An induction-type brake-alarming triggering device with a self-adaptive structure, wherein the device comprises a mounting base (1) provided at a brake-lever base or a handle bar on a side of a brake handle, an power-supply module (2) and a micro-controlling module (3) are provided in the mounting base (1), and the micro-controlling module (3) is wirelessly connected to an external warning light via a wireless-signal emitting module;

• and
• the power-supply module (2) is connected to the micro-controlling module (3);
• wherein a first mounting through hole (1a) is provided on one side of the mounting base (1) that faces the brake handle, a self-adaptive elastic extending assembly (4) is provided at an opening part of the first mounting through hole (1a), and an induction-type sensor (5) facing the brake handle is provided at the self-adaptive elastic extending assembly (4);
• in an initial state, a distance between the induction-type sensor (5) and the brake handle is 0.5-5 cm, and when the brake handle is moved toward the handle bar to perform a braking action, an intensity of a light ray that is reflected back from the brake handle and received by the induction-type sensor (5) is increased or a duration of the reflecting-back of the light ray is reduced, and the induction-type sensor (5) sends a braking signal to the micro-controlling module (3);
• and
• when the brake handle touches a sensing terminal, the self-adaptive elastic extending assembly (4) correspondingly contracts.
