Compared with the prior art, the utility model discloses utilize the digital regulation resistance output resistance, can obtain the biggest brake force in the short time, combine pincerlike stopper to brake simultaneously, can effectively brake electric bicycle, simple structure, low in manufacturing cost safely.
Description
Technical field
The utility model relates to Electrical Bicycle technical field, particularly a kind of emergency braking apparatus of Electrical Bicycle.
Background technology
At present, the brake equipment of traditional Electrical Bicycle is substantially all friction type brake device, its drawback mainly can not be applied in the occasion of excessive velocities, if excessive velocities, friction force produces amount of heat and cannot get rid of in time and can damage parts, and can noise be produced, easy friction coefficient affected by environment changes and reduces function.Safe requirement can not be met simply by virtue of traditional mode, and the brake mode application of electromagnetic adsorption is also immature, easy inefficacy, so on market, existing bicycle disc brake is friction-type is mostly main, even if there is resistance braking, is also as simple additional function, has an effect when motor speed is slower, the needs of Quick brake can not be realized completely, do not embody the independence of resistance braking completely.
Summary of the invention
The purpose of this utility model be to solve prior art problem deficiency and a kind of emergency braking apparatus of Electrical Bicycle is provided.
For achieving the above object, the utility model is implemented according to following technical scheme:
A kind of emergency braking apparatus of Electrical Bicycle, be arranged on vehicle frame, vehicle frame is provided with digital regulation resistance, brake control system, direct supply, permanent magnet brushless electromotor, each several part connects with wire by circuit series mode, is followed successively by direct supply or digital regulation resistance, permanent magnet brushless electromotor, brake control system; Namely direct supply and digital regulation resistance can only be positioned on series circuit by one simultaneously; Described brake equipment also comprises brake disc, slipper, brake shell, described slipper is set to two and is distributed in brake disc both sides, lead screw shaft connects side slipper, brake shell connects opposite side slipper, lead screw shaft and brake shell are screw thread pair, and the other end of described lead screw shaft is fixed with rocking arm by back-up ring and screw.
As further preferred version of the present utility model, described direct supply is the storage battery of Electrical Bicycle.
Compared with prior art, the utility model utilizes in Electrical Bicycle integrated circuit special speed controller, directly can obtain the digital signal of rotating speed, make digital regulation resistance output resistance as an analog quantity, the change of rotating speed can show as the change of analog quantity voltage, and this voltage is as the input of digital number potential device, control the break-make of thyristor, change resistance value in circuit series, realize the optimum load resistance needed, maximum braking force can be obtained at short notice; Brake in conjunction with Forcipated brake simultaneously, can safe and effective braking Electrical Bicycle, structure is simple, low cost of manufacture, installs, uses, easy to maintenance, good in economic efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is schematic circuit diagram of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, the utility model is further described, is used for explaining the utility model in the illustrative examples of this utility model and explanation, but not as to restriction of the present utility model.
The emergency braking apparatus of a kind of Electrical Bicycle as shown in Figure 1 and Figure 2, be arranged on vehicle frame, vehicle frame is provided with digital regulation resistance, brake control system, direct supply, permanent magnet brushless electromotor, each several part connects with wire by circuit series mode, is followed successively by direct supply or digital regulation resistance, permanent magnet brushless electromotor, brake control system, namely direct supply and digital regulation resistance can only be positioned on series circuit by one simultaneously, described brake equipment also comprises brake disc 1, slipper 3, brake shell 2, slipper 3 is set to two and is distributed in brake disc 1 both sides, lead screw shaft 7 connects side slipper 3, brake shell 2 connects opposite side slipper 3, lead screw shaft 7 and brake shell 2 are screw thread pair, the other end of lead screw shaft 7 is fixed with Rocker arm 4 by back-up ring 5 and screw 6, during use, brake disc 1 is arranged on the wheel hub of Electrical Bicycle, brake shell 2 floats and is arranged on vehicle frame, Rocker arm 4 is connected by lock silk with the brake handle of Electrical Bicycle, hold brake time, brake pulling wire pulls Rocker arm 4, the emergency braking that Rocker arm 4 drives lead screw shaft 7 to rotate an angle namely to realize wheel hub.
Preferably, described direct supply is the storage battery of Electrical Bicycle.
The direct supply that general Electrical Bicycle adopts is mostly the direct supply of 36-48 volt, and the maximum current that permanent magnet brushless electromotor bears is three times of rated current of normally working.
First, in Electrical Bicycle driving process, run into emergency situation need braking, navigating mate is by acting on the parking brake handle on handlebar, control brake control system, the energy resource system of Electrical Bicycle is disconnected rapidly with Electrical Driving System of Electrical Vehicle immediately, permanent magnet brushless electromotor loses propulsive effort, at this moment brake control system makes permanent magnet brushless electromotor and digital regulation resistance composition loop, start to enter the resistance braking stage, as long as chaufeur controls enabling of brake control system, digital regulation resistance just can be made along with the change of electrical salf-walking vehicle speed, by the change of analog quantity on speed gage, namely the voltage of digital regulation resistance input end changes, the continuous change of output resistance can be realized, the size of the stable and electric current of electric current when ensureing to keep permanent magnet brushless electromotor to reverse in resistance braking process, when avoiding reversion, powerful electric current is to the damage of permanent magnet brushless electromotor moment, when brake release needs to start enforcement, chaufeur is by controlling brake control system, the loop that permanent magnet brushless electromotor and digital regulation resistance are formed disconnects, be connected with direct supply, again the energy resource system of Electrical Bicycle is allowed to be connected with Electrical Driving System of Electrical Vehicle immediately, permanent magnet brushless electromotor obtains propulsive effort, enters normal travel phase.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
