A bicycle with automatic mileage calculation

Abstract

The embodiment of the invention provides a bicycle for automatically calculating mileage. The bicycle comprises a bicycle body, a Hall sensor, a power supply, a processing module, a display module andat least one magnetic element, wherein the at least one magnetic element is arranged on a wheel of the bicycle; when the wheel rotates by a circle, the Hall sensor acts with all the magnetic elementsto respectively generate pulse signals; the processing module is electrically connected with the Hall sensor and is used for detecting the pulse signals and calculating the mileage of the to-be-tested bicycle according to the pulse signals; the display module is electrically connected with the processing module and is used for displaying the mileage of the bicycle. The bicycle provided by the invention has the advantages that the mileage of the bicycle can be accurately calculated, riding data is conveniently viewed by a user, riding efficiency is improved, and current riding state is learned.

Description

【Technical field】 [0001] The invention relates to the technical field of bicycles, in particular to a bicycle with a hall sensor digital odometer and a novel braking system. 【Background technique】 [0002] While bicycles are used as a means of transportation, the needs of users are also constantly increasing. They hope to record the mileage of a single trip, so as to understand the distance between two places; or to understand their exercise in time, prevent excessive exercise, and assist in achieving fitness goals. Therefore need to develop a kind of bicycle that calculates mileage automatically. The Hall element has the following properties: When the external magnetic field is perpendicular to the current direction of the semiconductor in the element, the carriers are deflected, and an additional electric field is generated perpendicular to the direction of the current and magnetic field, thereby generating a Hall potential difference at both ends of the conductor. The Ha...

[0003] In addition, the existing types of bicycle brakes include disc brakes and V brakes. Disc brakes have been widely used in high-end bicycle brake systems due to their good braking effect and basically no heat attenuation problem. However, the disc brake structure has the following defects: 1. The front and rear oil pressure pipes of the front and rear wheel hydraulic disc brakes generally use oil pressure pipes of the same diameter and specification. When using the front and rear brake handles of the brake, although the hydraulic oil in the front and rear oil pressure pipes will flow at the same speed in theory, in fact, the length of the rear wheel oil pressure pipe is much longer than the length of the front wheel oil pressure pipe. , therefore, the hydraulic oil in the oil pressure tube of the rear wheel will be subject to greater frictional resistance, so that the braking action time of the hydraulic disc brake of the rear wheel will be slightly longer than that of the hydraulic disc brake of the front wheel, so the front wheel 1. There will be obvious brake actuation time difference between the rear wheel hydraulic disc brakes, which will affect the control balance of the whole vehicle. In severe cases, it may even easily cause the vehicle body to lean forward and cause safety accidents; When there is an obstacle in front of you or you need to slow down, you need to operate the brakes to slow down the car body. However, the existing disc brake system uses a disc brake system for both front and rear brakes, or uses disc brakes and V brakes for joint braking. The above two types of braking Both methods are difficult to achieve smooth deceleration, because the braking effect of disc brakes is better, so when a small force is applied, it is easy to lock up and it is difficult to control, while the deceleration of V brakes depends entirely on the driver's finger force to adjust the angle of the brake clamp , the force needs to be controlled by the driver, and it is not easy to achieve smooth deceleration
