Problems solved by technology

[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

Abstract

The invention relates to a bicycle tail speed measuring device with a positioning function, comprising a GPS positioning machine and a pointer, a protective casing is installed on the left side of the GPS positioning machine, a contact rotating wheel is installed in the middle of the rotating shaft, and the centrifugal A movable plate is installed above the disc, a rolling bearing is installed on the outside of the rotating shaft, a pressure spring is installed above the sliding plate, and a connecting ring is arranged above the pressure spring, and a steel cable is connected above the connecting ring. A pointer rotating shaft is arranged below the pointer, and a code dial is installed on the outside of the pointer rotating shaft, and a multi-layer protective layer is installed under the code dial, and a steel cable protection rod is arranged on the right side of the multi-layer protective layer. A disc spring is installed below the pointer rotating shaft. The invention is provided with multi-layer protective layers, and the multi-layer protective layers adopt elastic rubber and stainless steel to ensure the normal use of the equipment outdoors and ensure the practicability of the equipment.

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...
