Abstract

The invention relates to a bicycle warning lamp, which belongs to the technical field of bicycles. The bicycle wheel sleeve is set in the inner hole of the turntable, and the two sides of the turntable are provided with a sink cavity and a slideway, and the sink cavity is connected with the slideway through a guide hole; a side plate with a sink cavity and a guide hole is installed on one side of the slideway of the turntable; the turntable and Piezoelectric vibrators are installed in the cavity of the side plate through the end cover. The number of piezoelectric vibrators on both sides of the slideway is equal and symmetrically installed, and the piezoelectric chip is installed close to the slideway. Connected; the piezoelectric vibrator is equipped with spring pads, and extrusion balls are installed in the turntable and side plate guide holes, and the extrusion balls are lightly pressed on the spring pads; cylindrical or spherical exciters are placed in the slideway. Advantages and features: use the inertial force of the exciter to excite the piezoelectric vibrator without fixed support; the structural parameters of the piezoelectric vibrator are reasonable, the power generation capacity is large, and the effective frequency band is wide; the piezoelectric chip only bears compressive stress and has high reliability; the formed bicycle warning light The required energy is self-sufficient, does not require batteries, and is easy to use.

Description

technical field [0001] The invention belongs to the technical field of bicycles, and in particular relates to a bicycle warning light. Background technique [0002] With the improvement of people's awareness of environmental protection and sports and fitness, cycling and exercising have become a fashion again. However, there are many motor vehicles in the city and there are no special bicycle lanes, and there are certain safety hazards for cyclists driving at night. In order to attract the attention of motor vehicle drivers and other cyclists, and reduce or avoid accidents causing harm to cyclists, more and more bicycle warning products have come out one after another, such as reflectors, warning lights, etc.; wherein the warning effect of warning lights is relatively high. Good, but it needs to be powered by chemical batteries, which need to be replaced frequently due to problems such as limited battery power and natural wear and tear. This not only causes great trouble t...
