Adjustable shared bicycle lock

Abstract

The invention relates to the technical field of anti-theft equipment, and discloses an adjustable shared bicycle lock which comprises an axle, a rotating disc is assembled on the side wall of the axle, a fixed disc is arranged outside the rotating disc in a sleeving mode, and a filling cavity filled with magnetorheological fluid is formed between the rotating disc and the fixed disc. According tothe adjustable shared bicycle lock, the viscosity of magnetorheological fluid is controlled through the size of the outlet of the magnetic block, then riding resistance is controlled, when a user onlynormally commences, the user selects a state with small resistance and normally cleans the bicycle to reach a destination, and when the user needs to do fitness, riding resistance is improved, and riding exercise intensity is increased; when the resistance is adjusted to the maximum, the shared bicycle can hardly be ridden, so that the purpose of limiting the use of the shared bicycle is achievedby replacing a traditional bicycle lock, and secondly, main parts are all located in the axle and the fixed disc, are slightly influenced by the external severe environment and reduce the failure rate.

Description

technical field [0001] The invention relates to the technical field of anti-theft equipment, in particular to an adjustable shared bicycle lock. Background technique [0002] Modern people have a fast pace of life and lack of necessary exercise. Many people are in a sub-healthy or overweight state. However, with the popularity of shared bicycles and healthy travel, many people not only use shared bicycles as a means of travel, but also Its an everyday fitness tool. [0003] Shared bicycles are usually used for short-distance commuting tools, which generally take less than half an hour, and because commuting time is usually during the peak traffic period, it is difficult to ride too fast. Therefore, if you want to use only commuting time to achieve For the purpose of exercising, its exercise intensity and amount of exercise are far from enough. Therefore, shared bicycles need to design devices that can adjust the difficulty of riding to meet the needs of some people for exer...

Problems solved by technology

[0003] Shared bicycles are usually used for short-distance commuting tools, which generally take less than half an hour, and because commuting time is usually during the peak traffic period, it is difficult to ride too fast. Therefore, if you want to use only commuting time to achieve For the purpose of exercising, the intensity and amount of exercise are far from enough. Therefore, shared bicycles need to design a device that can adjust the difficulty of riding to meet the needs of some people for exercising

[0004] On the other hand, as a means of public transportation, shared bicycles will, to a certain extent, be subject to malicious damage and possession by some people. Especially for the lock part of shared bicycles, the probability of being considered damaged is relatively high. Secondly, shared bicycles The car lock has a large movement stroke, and after a long time of use, the incidence of deformation or rust is high, making it difficult to open or lock the car lock
