Description

Anti-sideslip device for bicycle

Technical Field

The invention belongs to the technical field of bicycles, and particularly relates to a bicycle sideslip prevention device.

Background

The bicycle is a traditional industry, has a history of more than 100 years, and due to the problems of environmental protection and traffic, the bicycle becomes a favorite traffic and fitness tool for residents in all countries in the world, particularly developed countries, the center of gravity of the bicycle industry in the world is being changed from a traditional transportation tool instead of walking to sports, mountain land and leisure, and the fitness bicycle is more and more popular with people along with the improvement of living standard of people.

However, since the bicycle is a two-wheel supporting structure, the bicycle can slide sideways during the advancing process, which brings potential safety hazards to the body-building exercise of people.

The traditional sideslip solution is realized by increasing the grip force of a vehicle, for example, patent application 201520719206.X discloses a widely-adaptable micro-resistance remote electric bicycle which mainly comprises a damping body, a handlebar, a wire-wound potentiometer, an electric control box, a hand brake, a front fork, a micro-resistance inflatable driving front wheel with a power motor at the center, a micro-resistance wide-wheel-side inflatable driving rear wheel, a battery, a back-off groove-shaped piece supporting framework, a left set of rear lifting wheel braking mechanism, a right set of rear lifting wheel braking mechanism and a pedaling speed change mechanism; two wing side plates of the back-off groove-shaped part supporting framework are positioned at the left side and the right side of the micro-resistance wide wheel edge inflating driving rear wheel, a set of lifting wheel brake mechanism is respectively arranged on the two wing side plates, when the braking and braking are accurate, the brake wheel lands, the micro-resistance wide wheel edge inflating driving rear wheel is lifted, the two wheels are changed into three wheels, and a rider does not need to get off the bicycle, so that the bicycle is stable and safe; the brake wheel is small and wide, the contact surface with the ground is greatly increased, the braking effect is obvious, and the braking is good; the driving resistance of the front and rear driving wheels is reduced by orders of magnitude during driving, and the wheel has strong ground gripping force, prevents sideslip and saves labor; the speed is increased quickly by adopting the pedaling speed change mechanism. The method has the problem of serious dependence on riding technical level of people and bicycle quality, the cost is often higher, and common people cannot bear the method.

Therefore, people have improved the structure of bicycle, improve through the brake auxiliary mechanism, like the electric bicycle brake structure that patent application 201320112324.5 discloses, especially relate to an electric bicycle prevents sideslip brake auxiliary device, its concrete structure includes a brake motor and a cam, brake motor installs on the tie-beam between rear wheel and automobile body, the cam links to each other with the brake motor shaft, the periphery of cam is around there being the brake cable, the one end of brake cable links to each other with the brake disc on the rear wheel, the other end of brake cable links to each other with the brake handle. This application passes through the cam structure, makes the brake cable elasticity change, makes the brake disc on the rear wheel stop tightly like this and the high-speed cycle in-process of releasing to avoided electric bicycle because of the sudden stop cause sideslip or drift situation, caused the car turnover even, increased electric bicycle's stability effect when emergency braking, improved electric bicycle brake performance, and effectively reduced electric bicycle's accident rate. 201420569779.4 discloses an auxiliary brake device for bicycle, which comprises a control panel on one side of the handlebar, a position sensor and an air pump connected with the control panel, wherein the position sensor is arranged on the handlebar and under the brake handle, the air pump is arranged on the seat tube of the rear support and connected with a power supply, and the output end of the air pump is connected with a spray gun. The application has the beneficial effects that: when the front brake and the rear brake are carried out, the spray gun sprays air to the ground to generate a reverse force, so that the instant sideslip or forward overturn during emergency braking is reduced, and personal injury of personnel is prevented. Although these methods have a certain anti-sideslip effect, the brakes are not acceptable because they are dangerous to the rider due to a certain impulse of the bicycle during the exercise.
