Bicycle positioning and tracking device

Abstract

The invention relates to a bicycle positioning and tracking device, and belongs to the technical field of bicycles. A hanger is mounted on a bicycle crossbeam, a hanger end cover is mounted at the end of the side wall of a main body, and a circuit board and a suspended magnet are mounted on the bottom wall of the main body; a limiting plate is mounted on a lower ring table on the side wall of the body, two groups of piezoelectric vibrators and leaf springs are mounted on an upper ring table, the piezoelectric vibrators are located on the upper and lower sides of the leaf springs, and spacer rings are welded between the piezoelectric vibrators and the leaf springs by pressure; the spacer rings are welded on outer ring leaves of the leaf springs by pressure, and the outer ring leaves are connected with inner wafers; pressure plates are mounted on the upper and lower sides of the inner wafers; the upper end of an inertia block is fixed on the pressure plate below the leaf springs, a hung magnet is mounted at the lower end of the inertia block, the hung magnet and the suspended magnet are mounted in such a manner that the same poles are opposite, and both the hung magnet and the suspended magnet are circular magnets; the two pressure plates, the inertia block and the hung magnet constitute an exciter; the piezoelectric vibrator is a sector-shaped or oblong cantilever beam formed by sticking a substrate with a piezoelectric sheet; the substrate is mounted close to the leaf spring, and the free end of the piezoelectric vibrator presses against an exciting ring.

Description

technical field [0001] The invention belongs to the technical field of bicycles, and in particular relates to a bicycle positioning and tracking device. Background technique [0002] In recent years, shared bicycles have been rapidly applied and promoted in people's lives, but random parking of bicycles and incidents of vandalism and theft also occur frequently. In order to better maintain and manage shared bicycles, the Shanghai Bicycle Industry Association clearly stipulates that shared bicycles must be equipped with on-board satellite positioning systems, which will help the government implement "electronic fence" management on shared bicycles. It can be seen that the positioning system is particularly important for the maintenance and management of shared bicycles. At present, more than 50% of shared bicycles on the market use satellite positioning technology, but the proportion of successful search by map is still low. The main reason is that the existing bicycle posit...

Problems solved by technology

At present, more than 50% of shared bicycles on the market use satellite positioning technology, but the proportion of successful search by map is still low. The main reason is that the existing bicycle positioning system is powered by batteries and cannot continue to work when the battery is exhausted; When the shared bicycle positioning system is powered by batteries, it not only needs to be replaced frequently, which wastes a lot of manpower and material resources, but also causes serious environmental pollution if the discarded chemical batteries are not properly disposed of.
