Embodiment Construction

[0016] The axle sleeve e of the bicycle wheel is fitted in the inner hole a4 of the turntable a through a fit fit. One side of the turntable a is provided with a stepped turntable ring cavity a1, and the other side is provided with an annular slide a3, and the turntable ring cavity a1 passes through the turntable guide hole a2. Connected with slide a3; the side with slide a3 on turntable a is equipped with side plate f through screws; side plate f is provided with side plate ring cavity f1 and side plate guide hole f2; turntable guide hole a2 and side plate The exit of the guide hole f2 on the side close to the slide a3 is spherical; both the turntable ring cavity a1 and the side plate ring cavity f1 are installed with a metal base plate c1 with a fan-shaped metal cantilever beam c11 and a metal cantilever beam c11 via screws and end cover b. The piezoelectric vibrator c is formed with the bonded piezoelectric wafer c2; the number of piezoelectric vibrators c installed on the tu...

Abstract

The invention relates to a self-luminous bicycle warning light, and belongs to the technical field of the bicycle. A bicycle wheel shaft sleeve is arranged in a rotary plate inner hole in a sleeving manner; an annular cavity and a sliding way which are connected through a guiding hole are arranged on the two sides of the rotary plate; a side plate which is equipped with an annular cavity and a guiding hole are mounted on the side face of the sliding way; substrates with metal cantilever beams are both mounted in the annular cavities of the rotary plate and the side plate through end covers; the metal cantilever beams and glued piezoelectric crystal plates form piezoelectric vibrators; the piezoelectric vibrators on the rotary plate and the side plate are equal in quantity and are symmetrically mounted; the piezoelectric vibrators are connected with LED lamps which are embedded on the end covers through wires; extrusion rolling balls are mounted in the guiding holes of the rotary plate and the side plate; rolling exciters are placed in the sliding way; a limiting surface is arranged on the end cover; and a sinking cavity is formed in the limiting surface. The self-luminous bicycle warning light has the advantages and characteristics as follows: the relative movement between the rotary plate and the corresponding exciters is realized through inertial force, and the piezoelectric vibrators are excited; the warning light does not need to be fixed and supported; after the piezoelectric vibrators are deformed, the stress on each point is the same, and only the pressure stress is supported; and meanwhile, the self-luminous bicycle warning light is high in electric energy production, high in reliability, self-sufficient in energy, energy-saving, environment-friendly, and convenient to use without requiring a battery.

Description

Technical field [0001] The invention belongs to the technical field of bicycles, and specifically relates to a self-luminous bicycle warning light. Background technique [0002] With the improvement of people's awareness of environmental protection and sports and fitness, cycling and exercise have become a fashion again. However, nowadays there are more motor vehicles in cities and no bicycle lanes, and there are certain hidden 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 the cyclists, more and more bicycle warning products have been introduced, such as reflectors and warning lights; among them, the warning effect of warning lights is better. Good, but it needs to be powered by a chemical battery, which needs to be replaced frequently due to limited battery power and natural loss. This not only caused great trouble to the rider and increased the cost of ...
