Bicycle alarming lamp

Abstract

The invention relates to a bicycle alarming lamp, and belongs to the technical field of bicycles. A bicycle wheel shaft sleeve is arranged in an inner hole of a rotary table in a sleeving manner; rotary table sinking cavities and sliding channels are separately formed in two sides of the rotary table; each of the rotary table sinking cavities communicates with the corresponding sliding channel through a guide hole; each side plate with a side plate sinking cavity and a guide hole is mounted on one side, with the corresponding sliding channel, of the rotary table; piezoelectric vibrators are mounted in the rotary table and the side plate sinking cavities through end covers, the number of the piezoelectric vibrators on one side of each sliding channel is the same as that of the piezoelectric vibrators on the other side of the corresponding sliding channel, and the piezoelectric vibrators on the two sides of each of the sliding channel are symmetrically mounted; piezoelectric crystal chips are mounted close to each of the sliding channels; each of the piezoelectric vibrators is connected with a corresponding LED lamp embedded on the corresponding end cover through wires; an elastic cushion is mounted on each of the piezoelectric vibrators; squeezing balls are mounted in the rotary table and the side plate guide holes, and are softly pressed on the corresponding elastic cushions; and cylindrical actuators or spherical actuators are put in each of the sliding channels. The bicycle alarming lamp disclosed by the invention has the advantages and the characteristics that the piezoelectric vibrators are actuated by the inertia force of the actuators, so that fixed supporting is not needed; the piezoelectric vibrators are reasonable in structural parameters, large in electric generating capacity, and wide in effective band; the piezoelectric crystal chips only bear compressional stress and are high in reliability; and the energy required by the bicycle alarming lamp disclosed by the invention is self-contained, and batteries are not needed, so that the bicycle alarming lamp is convenient 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...
