The specific embodiment
In order further to understand structure of the present utility model, feature and other purpose, now be described in detail as follows in conjunction with appended preferred embodiment, illustrated preferred embodiment only is used for the explanation the technical solution of the utility model, and non-limiting the utility model.
Embodiment:
As shown in Figure 1, 2, 3, a kind of Electrical Bicycle brake handle, comprise: the mechanical hatching gate brake gear, also comprise the electromagnetic braking brake gear, the electromagnetic braking brake gear comprises brake spanner 6 and brakes main body 7, brake is captiveed joint spanner 6 tops with arc-shaped magnet 2, captive joint with blockade contact head 4 in the bottom; Brake is provided with magnet sensor block 1 to main body 7 tops, and the bottom is provided with contact switch 5; Arc-shaped magnet 2 is adaptive main body 7 arc magnet track 3 with brake; Described mechanical hatching gate brake gear comprises brake cable hook 9, arc bayonet socket 8 and places the brake cable terminal 10 at arc bayonet socket 8 places, and brake cable hook 9 is positioned at arc-shaped magnet 2 tops, and is fixed on brake on the spanner 6, and arc bayonet socket 8 is arranged at the top of arc-shaped magnet track 3.
Electromagnetic braking part: pinch brake degree by the 1 output electric signal size reflection of a magnetic induction module during braking, magnetic induction module 1 induction is the formation magnetic field of arc magnet 2, when arc-shaped magnet 2 slides in track 3, magnetic induction module 1 can produce an electric signal, deliver to Electric Bicycle Driver, the control motor carries out electromagnetic braking; Arc-shaped magnet 2 slides spanner 6 with setting about pinching brake in track 3; Brake is interior blockade contact head 4 and contact switch 5, the electric signal of being responsible for electric bicycle driving force whether export and magnetic induction module 1 can the generation electric signal whether gating is effective.
The mechanical hatching gate part: arc bayonet socket 8 blocks the cylindrical brake cable terminal 10 of brake cable, when not spurring brake cable terminal 10, plays by brake cable hook 9 fixedly brake cable effect, brake cable hook 9 is connected brake on the spanner 6, along with spanner 6 actions are moved in brake, be used for spurring brake cable terminal 10 and carry out brake sticking brake.
As shown in Figure 1: when spanner 6 is not moved in brake, brake is in closure state to spanner 6 and brake handle, block contact head 4 and be pressed on the contact switch 5 this moment, contact switch 5 disconnects, locking signal output this moment high-impedance state, propulsive effort does not block, so magnetic induction module 1 output electric signal will can not carried out electromagnetic brake by controller; Brake cable hook 9 is drawing brake string terminal 10 not, and brake cable terminal 10 is stuck on the arc bayonet socket 8, and mechanical hatching gate is not worked.
As shown in Figure 2: when the driver pinches brake spanner 6, this moment, spanner 6 was drawn back in brake, blocking contact head 4 separates with contact switch 5, contact switch 5 conductings, propulsive effort blocks and magnetic induction module 1 gating, arc-shaped magnet 2 is braking the drive lower slider of spanner 6, the magnetic field that magnetic induction module 1 is sensed changes, the output signal respective change, deliver to controller control electromagnetic braking level of torque, pinch a degree under this state when maximum, brake cable hook 9 just touches but does not spur brake cable terminal 10, therefore magnetic induction module 1 can produce electric signal and delivers to controller and carry out electromagnetic braking, and the mechanical hatching gate brake is not worked.So brake is spanner 6 closure states the interval of having only electromagnetic braking work to this state.
As shown in Figure 3: if advance to continue on this basis to pinch brake spanner 6, magnetic induction module 1 meeting generation electric signal is delivered to controller and is carried out electromagnetic braking, and the mechanical hatching gate braking is started working this moment, brake cable hook 9 replaces arc bayonet sockets 8 to block and spur brake cable terminal 10 carrying out brake sticking brake, so mechanical hatching gate begins to brake cooperative interval for electromagnetic braking and mechanical hatching gate behind the place in operation.
