Drive module.
The utility model is to be achieved by the following technical programs：
A kind of drive module of bicycle, which is characterized in that including：Upper fork, lower fork, middle pipe, Five-way tube, axis, trailing wheel,
Chain wheel, flywheel and hollow insertion pipe,
The front end and the upper end of middle pipe of the upper fork and the rear end of insertion pipe are affixed, the front end of the Five-way tube and lower fork and
The lower end of middle pipe is affixed, and upper fork, lower fork and middle pipe surround drive module supporting rack jointly,
Detent mechanism is equipped in the insertion pipe front opening, the detent mechanism includes support plate, is symmetrically set in support
The spring leaf of plate both sides and the positioning column being fixed on the outside of spring leaf are symmetrically provided with positioning post holes, positioning column on the insertion pipe
Free end from positioning post holes be pierced by,
Axis is equipped in the Five-way tube, the both ends of the axis have been respectively and fixedly connected with crank, the free end peace of the crank
Equipped with pedal, the chain wheel is installed on axis,
The trailing wheel is installed on the rear end of fork and lower fork, and flywheel is connected on trailing wheel, and the flywheel passes through chain with chain wheel
Item is driven.
Preferably, backpedalling brake is installed on the trailing wheel.
The utility model has the beneficial effects that：
The utility model structure novel, reasonable design can be attached by insertion pipe with bicycle other assemblies, peace
Dress and disassembling section are simple and fast, small after fractionation, occupy little space, and are convenient for storing and transport, work as bicycle assembly
When damaging, component can be repaired or replaced in time.
Description of the drawings
Fig. 1 is the main structure diagram of the utility model.
Fig. 2 is the dimensional structure diagram of the utility model.
Fig. 3 is the partial enlarged view of insertion pipe front end.
In figure：It is pitched on 1., 2. lower forks, 3. middle pipes, 4. Five-way tubes, 5. axis, 6. trailing wheels, 7. chain wheels, 8. insertion pipes, 9.
Fagging, 10. spring leafs, 11. positioning columns, 12. cranks, 13. pedals, 14. chains.
Specific implementation mode
In order to make those skilled in the art more fully understand the technical solution of the utility model, below in conjunction with the accompanying drawings
The utility model is described in further detail with most preferred embodiment.
As shown, the utility model includes：Upper fork, lower fork, middle pipe, Five-way tube, axis, trailing wheel, chain wheel, flywheel and in
Empty insertion pipe,
The front end and the upper end of middle pipe of the upper fork and the rear end of insertion pipe are affixed, the front end of the Five-way tube and lower fork and
The lower end of middle pipe is affixed, and upper fork, lower fork and middle pipe surround drive module supporting rack jointly,
Detent mechanism is equipped in the insertion pipe front opening, the detent mechanism includes support plate, is symmetrically set in support
The spring leaf of plate both sides and the positioning column being fixed on the outside of spring leaf are symmetrically provided with positioning post holes, positioning column on the insertion pipe
Free end from positioning post holes be pierced by,
Axis is equipped in the Five-way tube, the both ends of the axis have been respectively and fixedly connected with crank, the free end peace of the crank
Equipped with pedal, the chain wheel is installed on axis,
The trailing wheel is installed on the rear end of fork and lower fork, and flywheel is connected on trailing wheel, and the flywheel passes through chain with chain wheel
Item is driven.
Preferably, backpedalling brake is installed on the trailing wheel, since drive module is connect with other assemblies by insertion pipe, stops
Mechanism of car can not be controlled by the mechanism in other modules, by backpedalling brake when bicycle needs slowing-down brake, be passed through
It is reversed trample pedal chain wheel made to rotate backward trailing wheel stopping can be made to rotate forward, the friction using wheel and ground makes bicycle
Stop, to complete to brake.
The installation of axis in the present embodiment, chain wheel, flywheel and backpedalling brake belongs to the prior art, does not do herein specifically
It is bright.
Insertion pipe in the present embodiment should be used cooperatively with outer be in the charge of, be in the charge of outside outside be provided with it is corresponding with positioning column fixed
Position hole, the open end being in the charge of outside is also connected with retaining mechanism, such as fast disassembly type anchor ear, is in the charge of is fixed in other bicycle modules outside
On, when component needs connection, the front end of insertion pipe is inserted into outer be in the charge of, positioning column is inwardly compressed under spring leaf effect,
Rotation insertion pipe makes positioning column be directed at location hole, and the free end of positioning column is popped up from location hole, while being locked by retaining mechanism
Conjunction is closed, can realize being bonded between component, when needing dismounting or component to need repairing, replaces between component, head
First retaining mechanism is opened, pinning two positioning columns with hand makes it be exited from location hole, stretches out insertion pipe and can be completed
It dismantles, the retaining mechanism used in the present embodiment is fast disassembly type anchor ear, and structure novel is easy to use, and user can be quickly complete
At installation or removal, operation difficulty is reduced, meanwhile, the bicycle after dismounting occupies little space, and user can be facilitated to store up
It deposits or carries, be convenient for routine use.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this
For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model
Within, any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
