Bicycle tail velometer capable of positioning

Abstract

The invention relates to a bicycle tail velometer capable of positioning. The velometer comprises a GPS positioner and a pointer, the left side of the GPS positioner is provided with a protective housing, the middle of a rotating shaft is provided with a contact rotation wheel, a movable plate is installed over a centrifugal disc, a rolling bearing is mounted outside the rotating shaft, a pressurespring is mounted on a slide plate, a connecting ring is arranged on the pressure spring, the upper of the connecting ring is connected with a steel rope, a pointer rotating shaft is arranged under the pointer, a stopwatch disc is mounted outside the pointer rotating shaft, multiple protection layers are mounted under the stopwatch disc, a steel rope protective rod is arranged on the right of theprotection layers, and a disc spring is mounted under the pointer rotating shaft. The velometer is provided with the protection layers, the protection layers include elastic rubber and stainless steel, normal use of equipment in the outdoor is ensured, and the practicality of the equipment is ensured.

Description

technical field [0001] The invention relates to the technical field of bicycle equipment, in particular to a bicycle tail speed detector with a positioning function. Background technique [0002] The speedometer at the rear of a bicycle is a commonly used auxiliary tool for bicycles, which enables users to observe changes in vehicle speed intuitively and improves riding safety. However, the existing speedometers at the rear of bicycles all use electromagnetic induction for speed measurement. In a strong magnetic environment, the equipment will be damaged, and the existing speedometer cannot be installed with GPS due to its small size, so the speedometer does not have the function of positioning. [0003] So we propose a bicycle tail speed detector with positioning function, so as to solve the problems mentioned above. Contents of the invention [0004] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a bicycle tail speed de...
