Crutch with time telling function

Abstract

The invention relates to the technical field of crutches, in particular to a crutch with a time telling function. The crutch comprises a support rod and a handle; the handle is arranged at one end of the support rod, and piezoelectric materials are inlaid in the support rod; the support rod is provided with a groove and a cover used for sealing the groove; the groove is internally provided with a voltage stabilizing circuit, a step-down circuit and a storage battery; the piezoelectric materials, the voltage stabilizing circuit, the step-down circuit and the storage battery are electrically connected in sequence; a hazard warning device is arranged on the handle, and the hazard warning device is electrically connected with the storage battery. According to the technical scheme, due to the fact that the piezoelectric materials are inlaid in the support rod, the piezoelectric materials are under pressure to generate voltage to supply electricity to the storage battery, and electric energy is provided for a clock; the crutch can be used as a common crutch and has the time telling function simultaneously, the structure is simple, use is convenient, and energy conservation and environmental protection are achieved.

Description

technical field [0001] The invention relates to the technical field of crutches, in particular to a crutch with a time telling function. Background technique [0002] Blind people cannot observe things outside, so their actions are extremely inconvenient. When they need to go out, they must rely on guide crutches for guidance. However, the existing crutches for the blind have relatively single functions and cannot meet the needs, especially When it falls or encounters danger, it cannot send a distress signal to the outside world in time, which is very inconvenient to use. [0003] The piezoelectric effect means that when certain dielectrics are deformed by external forces in a certain direction, polarization will occur inside, and at the same time, opposite positive and negative charges will appear on its two opposite surfaces. When the external force is removed, it will return to the uncharged state. Piezoelectric materials are crystalline materials that generate a voltag...
