Background technology
Become the main walking-replacing tool of people's city traffic at China's Electrical Bicycle, its owning amount improves year by year, Electrical Bicycle operates on the slow lane at ordinary times, its drg designs according to the ordinary bicycle brake system usually, braking effect and stability are well imagined, traffic accident is high, security situation is quite severe, therefore under China's reality road traffic condition, strengthen the Electrical Bicycle safe operation and just seem especially important, and the drg most important safety component that is Electrical Bicycle, improving the Electrical Bicycle deceleration and stopping performance is guarantee the Electrical Bicycle safe operation basic, the significant Electrical Bicycle drg of a kind of braking resultant effect, one plays an important role at minimizing traffic accident aspects surely, and it is mathematical to the effect of safety traffic.
We think in investigation and analysis, be subjected to the restriction of power and energy consumption, the tyre width of Electrical Bicycle is restricted, realize the car load braking and keep vehicle stabilization to be not enough so rely on the tire of vehicle and ground friction merely, though people improve existing wheel brake system continuous the correction, in the research and development of Electrical Bicycle brake system finally, new approach certainly will to be opened up, make many persons of this car brake system combination, improve the safety performance of Electrical Bicycle under complicated environmental condition.
Summary of the invention
At Electrical Bicycle brake system present situation, the invention provides a kind of emergency brake for electric bicycle of novel structure, it is an independent integral body, can make Electrical Bicycle is to increase by one on the basis directly and the braking force of ground friction at existing wheel braking, to shorten the stability of its emergency stopping distance and Motor Vehicles in Emergency Brake Application, improve safety performance.
The present invention is achieved in that emergency brake for electric bicycle comprises direct brake system, force aid system for braking, maneuvering system, circuit control system, maneuvering system connects with direct brake system through connecting rod assembly, and is simultaneously in parallel through the existing front and rear wheel drg of drag-line and Electrical Bicycle; The force aid system for braking assembly connects with direct brake system through connector; Circuit control system is serially connected among the existing circuit of Electrical Bicycle;
Described direct brake system also comprises connector, cushion rubber, frame, friction shoe, spring, base plate, connector is fixed on the vehicle frame, and frame is hinged on the connector, is provided with cushion rubber, base plate in the frame, fixing friction shoe in the base plate, spring is connected between frame and the vehicle frame;
Described maneuvering system also comprises brake pedal, pull bar, housing, cover plate, and housing is fixed on the vehicle frame, with brake pedal and pull bar and drag-line interlock, and is provided with reset attachment through transmission device;
The input end of switch and Chang Kai mouth are serially connected in the existing supply line of Electrical Bicycle in the described circuit control system, and the normally closed mouth of switch is connected by the controller of force aid system for braking.
Simultaneously, connector is fixed on the vehicle frame, and the force aid system for braking assembly is hinged on the connector, and force aid system for braking is power with the electromagnetic force.
Secondly, connecting rod assembly is rigidity bar linkage structure (shown in the figure), or the flexible cable structure.
Once more, the housing fasten with screws is (being that screw is fastening shown in the figure) on vehicle frame, or be weldingly fixed on the vehicle frame, and cover plate is fixed on the housing, prevents daily by water and dust intrusion.
Its working process is: when the Electrical Bicycle emergency braking, pin is stepped on brake pedal (3), through transmission device pull bar (4) is rotated, drive direct brake system mid frame (9) rotation by connecting rod assembly (6), the friction shoe (11) that is fixed in the base plate (16) lands, the normally closed mouth of switch (19) is connected in the circuit control system at this moment, the controller of force aid system for braking (20) work, electromagnetic force descends push rod in the force aid system for braking, give direct brake system mid frame (9) applied thrust again through connector (13), produce braking force by friction shoe that lands (11) and ground direct friction.Simultaneously, the transmission device in the maneuvering system makes drag-line (2,12) interlock, and the existing front and rear wheel drg work of Electrical Bicycle realizes wheel braking simultaneously.
When the Electrical Bicycle emergency braking finishes, loosen the brake (3), maneuvering system resets, switch in the circuit control system (19) restores, under the effect of spring (14), directly brake system mid frame (9) counter-rotating, friction shoe (11) rising that is fixed in the base plate (16) resets, and wheel braking is also removed simultaneously.
Effect of the present invention is:
(1). when emergency brake for electric bicycle is worked, can produce brake resistance at once, making Electrical Bicycle is to increase by one on the basis directly and the braking force of ground friction at existing wheel braking, can shorten stopping distance greatly.
(2). when emergency brake for electric bicycle was worked, there had been two strong points at the Electrical Bicycle rear portion, can improve the stability of Electrical Bicycle when emergency braking, prevented unexpected injury.
(3). it does not consume energy at ordinary times, and own wt is less, and the Electrical Bicycle tractive performance is not had influence.
(4). it plays the double insurance effect to the existing brake system of Electrical Bicycle, just in case when former brake system produces fault, emergency brake system can directly play a role.
(5). in the winter time or under the severe environmental conditions such as rainy day, both hands are busy with maneuver vehicle, adopting the braking that tramps with one's feet and be unusual match operation demand.
