Shockproof and drop-resistant bicycle stopwatch

Abstract

The invention relates to the technical field of shockproof and drop-resistant bicycle stopwatches, and discloses a shockproof and drop-resistant bicycle stopwatch. The stopwatch comprises a stopwatchfixing seat and an electrorheological fluid storage bag, the electrorheological fluid storage bag is fixedly connected with the interior of the stopwatch fixing seat, and the electrorheological fluidstorage bag is filled with electrorheological fluid. According to the shockproof and drop-resistant bicycle stopwatch, the stopwatch is placed on the upper end face of the electrorheological fluid storage bag, the stopwatch is pressed down with force, the electrorheological fluid storage bag deforms along with the stopwatch, the electrorheological fluid presses down a pushing pressing block, the pushing pressing block extrudes gas in an extrusion cavity to the top, when a movable block moves to an opening of the extrusion cavity, an adjusting supporting rod is driven by a compression spring toautomatically open to assist in adjusting the shape of the electrorheological fluid storage bag, meanwhile, a dielectric plate moves downwards, an electrode plate is powered on, and therefore the electrorheological fluid is changed into a solid state from a liquid state due to electric field changes, the stopwatch is fixed, the installation stability is high, and the stopwatches can be of different sizes and shapes.

Description

technical field [0001] The invention relates to the technical field of an anti-shock and anti-fall bicycle stopwatch, in particular to an anti-shock and anti-fall bicycle stopwatch. Background technique [0002] The bicycle stopwatch is an electronic product used to calculate mileage and speed. The working principle of the stopwatch is: when the rim rotates, the sensor captures the information brought by the induction magnet, and transmits it to the stopwatch through the sensing line. After this is processed, information such as speed per hour and mileage are calculated, which is determined by the induction magnet installed on the steel bar of the front rim, the sensor on the front, along the connection line, the stopwatch seat on the grip and the code on the seat. Table, the existing stopwatch is generally auxiliary fixed on the bicycle by the stopwatch holder. [0003] However, due to the inconsistency of the shape of the stopwatch, generally one kind of stopwatch needs t...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a shockproof and drop-resistant bicycle stopwatch, which has the advantages of simple operation, convenient installation, adaptability to stopwatches of various sizes, and strong adaptability, and solves the problem of The shape of the watch is inconsistent. Generally, a stopwatch needs to be installed and fixed corresponding to the matching stopwatch seat. However, when the user replaces the stopwatch product, it needs to be replaced together with the stopwatch stand, which is time-consuming and laborious, and increases the cost of the problem.
