Line is vertical with the first bolt 14.Specifically, eccentric cam 17 and the first bolt 14 can be fixed on the first bolt 14 by installing
Pin shaft 19 realize rotatable connection, and the axle center of the pin shaft 19 is not located at 17 center of eccentric cam, when eccentric cam 17
It turns to when being located on adjusting block 13 away from the farthest end face a in 19 axle center of pin shaft, adjusting block 13 can be pushed to can not move.Into one
Step, one end of handle 18 is partial in the axle center that eccentric cam 17 is connect with pin shaft 19, this structure makes eccentric cam 17 in handle
18 one end endpoints to 19 axle center of pin shaft distance be less than 18 other end of handle endpoint a to pin shaft axle center distance (i.e. it is above-mentioned extremely
The farthest end face away from pin shaft axle center).Since the first bolt 14 is fixed on main boom 9, in the feelings that 19 axle center of pin shaft is fixed
Under condition, when the endpoint a by rotating the first in command 1 to 17 opposite handle of eccentric cam, 18 other end is contacted with adjusting block 13 (i.e.
Push handle 18), adjusting block 13 can be driven to push into regulating tank 92；And after pulling handle 18 upwards, it can make eccentric convex
The distance of end face to the pin shaft 19 of wheel 17 returns back to original state, to make adjusting block 13 have up and down gap, therefore
Main boom 9 is set to reply swingable state.
As shown in Fig. 4, preferably, it includes the master being fixedly connected with fixed device that above-mentioned power assisting device, which may is that,
Machine fuselage 2, the linear electric machine 6 being assemblied in main machine body 2, the rack 3 being connected on the output shaft 61 of linear electric machine 6, assembly
In the brushless motor 10 in rack 3 and the friction tire 11 for being contacted with cycle wheel 52.The friction tire 11 is nested
It in the output shaft surface of brushless motor 10, is rotated by the rotate driving friction tire 11 of brushless motor 10, and passes through friction pulley
Tire 11 contacts the rotation that the frictional force generated drives cycle wheel 52 with cycle wheel 52.
As shown in attached drawing 9 and 10, the rack 3 includes c-type frame 32 and the guide rod for being fixed on the outer two sides of c-type frame 32
31, the brushless motor 10 is connected in c-type frame 32, and the axis that brushless motor 10 rotates is vertical with two guide rods 31.It is described
2 two sides of main machine body are equipped with the guide rail 21 that the guide rod 31 is embeddable and slides, and the output shaft of guide rail 21 and linear electric machine 6
61 moving direction is parallel, with the moving direction of this structure limitation rack 3, makes rack 3 only with respect to main machine body 2 along linear electric machine
6 61 moving direction of output shaft moves in parallel.In addition, guide rod 31 is equipped with limited block 33 in the rear and front end outside guide rail 21,
And two the spacing of limited block 33 be greater than the length of guide rail 21 and prevent rack 3 online with the shift motion of this structure limitation rack 3
Property motor 6 driving under be detached from main machine body 2.
As shown in attached drawing 5 to 10, the output shaft 61 of linear electric machine 6 and the c-type frame 32 of rack 3 are on mutual corresponding end face
It is equipped with connection buckle 71, the both ends of the pressuring spring 7 are divided to fastener in two connecting hooks 71, making pressuring spring 7 solid by this method
Due between the output shaft 61 and rack 3 of linear electric machine 6.The elastic telescopic variable generated by 6 elastic deformation of pressuring spring, can
Make brushless motor 10 oppress cycle wheel 52 pressure have certain variable, can effectively prevent friction tire 11 always with
Excessive pressure is applied to cycle wheel 52 and leads to the tyre break of wheel 52, or with the too small pressure of tire 11 that rubs
It is applied to cycle wheel 52 and causes the frictional force of friction tire 11 and cycle wheel 52 that can not maximize and be converted into driving
The torque that cycle wheel 52 rotates.Also, when bicycle passes through bumpy road, road surface forms the weight that resistance is equivalent to people
In addition the weight of bicycle, causes up to a hundred kilograms of active force indirectly to impact power assisting device through cycle wheel, if things go on like this,
It is easy to cause linear electric machine to damage, and power assisting device overall structural strength is easy to cause to be deteriorated.Therefore, in the road surface ring to jolt
Under border, the buffer function of spring offsets the active force that wheel applies power assisting device, while can guarantee the Yu Zihang of friction tire
Effective transmission of vehicle wheel.
The utility model operating process:
Firstly, entire fixed device and the utility model power assisting device to be fixed on to the rear fork of bicycle 5 by Fast detachable unit 4
On pipe fitting 51；
Then, power assisting device is adjusted to the angle of corresponding 52 position of cycle wheel by rotation main boom 9；
Finally, pushing the handle 18 of the first in command 1, eccentric cam 17 can be driven along the axis rotation of pin shaft 19, caused partially
Cardiac prominence wheel 17 pushes in adjusting block 13 to regulating tank 92, makes the double wedge 16 of adjusting block 13 and interlocks with the double wedge 16 of adjusting block 81
Engagement, and move up and down 13 fixation of adjusting block can not, so that being restricted main boom 9 can not continue to rotate.It is realized and is helped with this
The adjusting of the angle of power device, make in this way can power assisting device can perfectly be suitable for various frameworks bicycle 5.
The course of work of power assisting device:
Firstly, power assisting device to be fixed on to the rear fork pendant 51 of bicycle 5 by the mode of operation of above-mentioned the utility model
On, and keep brushless motor 10 corresponding with the tyre surface of cycle wheel 52, which is contact of the cycle wheel 52 with ground
Face；
Then, driving linear electric machine 6 drives rack 3 mobile to 52 direction of cycle wheel, until brushless motor 10 rubs
Tire 11 is wiped to move along the positive tyre surface to cycle wheel 52 in 21 direction of guide rail；
Finally, driving brushless motor 10 rotates, make the drive rotation of cycle wheel 52 of tire 11 that rubs, to realize voluntarily
The electric drive of vehicle 5.
The above is only the specific embodiments of the present invention, but the design concept of the present invention is not limited thereto,
All non-essential modifications to the present invention made by this concept should belong to the row for invading scope of protection of the utility model
For.
