Take turns the driving ring 41 of 5 settings, and one can be socketed this driving ring 41 rotationally and be arranged at
This fluted disc sleeve 2 reducing sleeve 42 for another flute profile wheel 5 setting.
Refering to Fig. 2, Fig. 4 and Fig. 5, this driving ring 41 has one for corresponding flute profile wheel 5
The driving ring body 411 arranged, and four be arranged at this driving ring body 411 and respectively blocking
Drive block 412 in two adjacent wheel between cog of corresponding flute profile wheel 5.
This reducing sleeve 42 has one and can be socketed this driving ring 41 rotationally and be arranged at this tooth
Dish sleeve 2 the reducing sleeve body 421, four for corresponding another flute profile wheel 5 setting set
It is placed in this reducing sleeve body 421 and is equipped in another flute profile wheel 5 two adjacent of correspondence respectively
The linked block 422 of wheel between cog, and four extended by this reducing sleeve body 421 outer ring surface and held
It is placed in the abaculus 423 of the described groove 21 of this fluted disc sleeve 2.
When this crank axle module 3 rotates forward, described drive block 412 pushes against described linked block 422
Synchronizing to rotate forward, when this crank axle module 3 stops rotating forward, described drive block 412 stops operating,
Described linked block 422 is rotated further an angle along with inertia.
Refering to Fig. 1,2,3,4, described flute profile wheel 5 is respectively arranged at this driving switching module 4
Driving ring 41 and reducing sleeve 42, and its material is permeability magnetic material.
When this crank axle module 3 rotates forward, the driving ring 41 of this driving switching module 4 is by being somebody's turn to do
Crank axle module 3 drives and drives flute profile wheel 5 synchronization of correspondence to rotate forward, and interlocks this reducing sleeve
42 and correspondence another flute profile wheel 5 synchronization rotate forward, this fluted disc sleeve 2 is with this driving switching model
The reducing sleeve 42 of group 4 synchronizes to rotate forward, and the gear position of the most described flute profile wheel 5 is corresponding.
Refering to Fig. 1,2,3,5, when this crank axle module 3 stops rotating forward, this driving ring
41 and the flute profile wheel 5 of correspondence stop operating along with this crank axle module 3, this reducing sleeve 42 and
Corresponding another flute profile wheel 5 is rotated further this angle along with inertia, makes described flute profile wheel 5
Wheel between cog produce dislocation.
Each magnetic sensing module 6 includes a magnetic of corresponding one of them flute profile wheel 5 setting
Ferrum 61 and a magnetic sensor 62, described Magnet 61 and described magnetic sensor 62 position
Fixing, each magnetic sensor 62 is respectively used to sense the magnetic field of corresponding Magnet 61 because of correspondence
Flute profile wheel 5 rotation and the change that produces, when the wheel between cog of described flute profile wheel 5 produces dislocation,
Described magnetic sensing module 6 exports a dislocation signal to interrupt this motor according to changes of magnetic field
The traveling power-assisted that 91 are provided.
In the present embodiment, described magnetic sensor 62 uses Hall element to implement, and described
Magnet 61 maintains static in a fixed plate 7 by being arranged at described magnetic sensor 62,

The most as shown in Figure 6, the gear teeth of the flute profile wheel 5 that each Magnet 61 is respectively adjacent to correspondence are peripheral
Arrange, and each magnetic sensor 62 is arranged at this Magnet 61 of correspondence and corresponding flute profile
Wheel 5 between, its principle as shown in Figure 7, Figure 8, in Fig. 7, when this flute profile wheel 5 the gear teeth
When this Magnet 61, owing to the material of this flute profile wheel 5 is permeability magnetic material, therefore this magnetic
The magnetic line of force comparatively dense that the position of sensor 62 is sensed, in Fig. 8, when this flute profile takes turns 5
The gear teeth away from this Magnet 61 time, the position of this magnetic sensor 62 magnetic force sensed
Line is sparse, whereby, it becomes possible to whether the gear teeth differentiating described flute profile wheel 5 synchronize or have mistake
Position.
As it is shown in figure 9, the set-up mode of described Magnet 61 and described magnetic sensor 62 also can
It is enough each Magnet 61 and axial along corresponding flute profile wheel 5 of each magnetic sensor 62
Interval is arranged, and neighbouring corresponding flute profile is taken turns the gear teeth of 5 and is divided into this flute profile wheel 5 of correspondence
Both sides, its operation principles is similar to above-mentioned, so not repeating, and the magnetic of described Magnet 61
The disposing way of pole can take turns 5 with N pole or S pole towards this flute profile according to actual demand, not
It is limited to this.
Refering to Fig. 1, Fig. 2 and Fig. 3, when generally using, trample forward as rider described in step on
During plate 92, this crank axle module 3 can be driven to rotate forward, and drive this driving ring 41 and right in succession
Flute profile wheel 5 synchronization answered rotates forward, and the drive block 412 of this driving ring 41 can push against this switching
Overlap the linked block 422 of 42 and make another flute profile wheel 5 rotating forward of this reducing sleeve 42 and correspondence,
And drive this fluted disc sleeve 2 to synchronize to rotate forward by described abaculus 423；And when rider to be carried out
When braking and stop trampling described pedal 92 forward, now crank axle module 3 stops rotating forward,
And make the flute profile wheel of this driving ring 41 and correspondence 5 stop operating, now this reducing sleeve 42 and right
Another flute profile answered is taken turns 5 and is rotated further this angle along with inertia, and makes described flute profile wheel 5
Wheel between cog produce dislocation, described magnetic sensing module 6 according to changes of magnetic field export this dislocation letter
Number to interrupt the traveling power-assisted that this motor 91 is provided.
Via above explanation, it is possible to the advantage of the present embodiment is summarized as follows:
By arranging the fixing described Magnet 61 in position, described magnetic sensor 62 and collocation
Described flute profile wheel 5, is not only able to detect rider and starts to stop trampling what described pedal 92 advanced
Moment, and can immediately interrupt the power-assisted of motor 91, and owing to only needing two groups of Magnet 61, magnetic
Property sensor 62 and flute profile wheel 5, during production and be not required to special process technology, element material becomes
This most relatively prior art is greatly lowered, therefore compared to prior art, it is possible to production is greatly reduced
Required technology, time and cost, have great advantage on market.
In sum, so the purpose of the present invention really can be reached.
