Description

Combined type lover electric bicycle capable of realizing four-person resultant force and self-charging

The technical field is as follows:

the invention belongs to the field of designing and manufacturing bicycles.

Background art:

the invention of the bicycle has a history of more than two hundred years from now, with the rapid development of various vehicles, the bicycle is no longer a favorite of the times for a long time, more and more bicycle lanes are occupied by electric vehicles and motor vehicles, and dirty air and urban noise also replace the original smooth of riding and flying on the road. It has to be acknowledged that bicycles seem to be more and more distant from our lives. However, what is the real current situation of bicycle travel in real life? Is there a need for people to ride a bicycle? How does a bicycle adapt to this rapidly developing society? In the face of these problems, we have recently seen that provincial cities have many "green lanes", "bicycle lanes", sidewalks, blind roads which are silently recovered and even repaired better and wider than before, and unfortunately, few bicycles are driven on them. With the improvement of living standard of people, people need to have a road condition suitable for various road conditions, such as getting on the street and getting off the countryside; getting people and carrying goods; the running is smooth and the stopping is stable; shading sun and rain; enter the elevator, enter the new bicycle of family's door. As the bicycle is not only a simple walking tool but also a new design is expected to enable the bicycle to have more functions capable of meeting the requirements of different occasions of families, the bicycle is used as a fun traffic demand for visiting friends and gathering, outing and body building, leisure shopping and the like, and the bicycle not only can bring convenience to the use of families, but also can give play to the functions of products and resources reasonably, is low-carbon, saves energy, reduces emission and creates civilized, harmonious and healthy social positive energy.

The invention comprises the following contents:

a combined type lovers electric bicycle capable of being jointly and automatically charged by four persons is characterized in that the safety problem that a plurality of traffic accidents are easily caused due to the fact that a patent Z L201720168458.7 and an invention patent publication number CN107399402A only can be effectively solved that the bicycle can only be dynamically balanced and can be overturned when the bicycle is parked in a slow running mode, the bicycle is stably and safely parked, safety regulations based on the safety problems, such as 'forbidding riders to carry people, forbidding riders to support umbrellas and forbidding to ride side by side' … … and the like, are solved, Z L201820116874.7 and an invention patent publication number CN 108045491A ideally solve the problems that a 400W (considering the upper limit of power of an electric bicycle which is singly ridden after a rider is used) motor and the climbing power is insufficient, all functions are not sacrificed on the basis of a patent Z L201720168458.7 and patent publication numbers CN107399402A and CN 108045491A, and the problems that the self-generating electricity is efficiently charged at a speed below 25 hour and the self-charging rate are solved.

Invention patent publication no: CN 107399402A' design rear (or front) wheel axle can be equipped with speed-limiting (15 km) bicycle motor, and can be used for uphill boosting, downhill feedback braking and power generation to charge battery. Although the problems that the self-charging of the electric power-assisted bicycle during riding is from 'none' to 'available' and from 'unavailable' to 'available' are solved, the static balance is realized by the 'two feet landing', the rider does not consider pedaling by himself after pressing the electric power-assisted bicycle, and the rider does not expect to pedal by manpower to generate electricity to charge the battery. The electric bicycle has no market demand, namely, no technical demand, and the 'all electric bicycles must adopt hub motors' becomes a deeply fixed technical prejudice, and no exception exists in the whole industry, and merchants really making up the 'electric power-assisted bicycle' advocated in the national standard, such as 'middle-mounted motors', modified 'mountain electric bicycles' and the like are considered to be 'out of service', are on the 'return way', are lagged behind and are eliminated; and the so-called trade company in the industry, rather than having a huge flower in "high, big, shang, yang", never think: the essence of the electric bicycle is that the electric power-assisted bicycle can be used when necessary, and the quality of the electric bicycle is changed into a motor vehicle or an electric vehicle when the quantity becomes less than the requirement of pedaling; the method is simple and practical, how to make the bicycle carry people, carry objects, support an umbrella, walk slowly (stop) and run side by side is achieved, the bicycle is safe, stable, light and labor-saving, even the bicycle can be electrically charged in a climbing and descending way … … CN107399402A is also brought into a dead-end museum, an in-wheel motor without a reduction gear and an internal clutch is used for an experiment, and therefore the battery can be charged reversely, but the conversion efficiency is low.

The invention uses a dual-purpose (electric/power generation) high-efficiency motor without any speed reducer, directly utilizes the high diameter ratio of the front (or rear) wheel and the driving wheel to realize speed reduction, and not only can keep the motor running in the working state with the highest efficiency no matter the motor is electric or power generation; the driving wheel can be simply and conveniently separated from and engaged with the wheel, the function of a high-efficiency clutch is achieved, and no mechanical transmission loss exists when the bicycle is ridden by pure manpower.

The motor is characterized in that when the motor is used for driving, the motor can ensure that the speed of the electric bicycle does not exceed 25 km/h even if the motor exceeds the rated rotating speed; under 25 km/h, especially when starting, the rotation speed of the motor is observed, the motor is enabled to be close to the rated rotation speed state as much as possible by matching with a clutch and a speed regulation handle, and the power is saved with high efficiency to the utmost extent, because the principle of the permanent magnet motor tells us that the torque is the highest only when the electromagnetic force (ampere turns) is equal to the force of a permanent magnet field, then the input current is increased, the rotation speed of the motor is not increased any more, the electricity is wasted in vain, the clutch can only be separated to enable the motor to be increased to the rated rotation speed, and the accumulated energy of the optimal power is exerted, for example, the diameter of a power generation chain wheel in the graph 3 is larger, the flywheel effect is achieved, and the power-assisted driving wheel can slowly close the clutch and increase the pedaling force; when the motor works in a power generation state, the higher the motor rotating speed is, the better the motor rotating speed is, the more the anti-positive permanent magnetic field force is cut by magnetic lines of force.

The working principle of the motor is illustrated in fig. 1, for the sake of simplicity, other circuits such as protection, control, hall, etc. are omitted here, and the following is illustrated by taking three-phase driving delta connection as an example: when the motor works in a driving state, the MOS tubes of the upper and lower arms driven by three phases are sequentially combined into V1-V2, V2-V3, V3-V4, V5-V4, V5-V6 and V1-V6 to supply power to the motor through K1, K2 and K3; when the motor works in a power generation state, K1, K2 and K3 are turned off, K4 is turned on, and current intensity can be manually controlled according to the will of a rider to rectify alternating current fed back and output by the motor and then charge a battery.

In order to make the motor work in a high-efficiency state as much as possible during running, the instrument panel is provided with a rotating speed display and a vehicle speed display of the motor in addition to general voltage and current displays.

The motor adopts a design of 'single end shaft outlet', one group of chain wheels are used for 'driving', the speed ratio of the chain wheels to a driving wheel is less than N: 1, so that the motor can work at the highest efficiency, the electric vehicle can start powerfully, and the running is not over-speed; the other group of chain wheels is used for generating electricity, and the speed ratio of the other group of chain wheels to the driving wheel is larger than N: 1, so that the motor can be switched to a power generation and charging working state when the electric bicycle is braked at any speed (of course, the motor is only in a theoretical ideal state, and the motor needs to be tested and debugged due to different materials actually). After the overall matching electric design is well debugged, the working state of the generator/motor of the motor is automatically switched according to the principle of 'automatic gear' of a car; automatically adjusting the magnitude of the charging current; the "cruise" speed is automatically maintained as preset. The automatic driving … … can be realized by matching with the automatic driving instrument, and the last sentence is only the last sentence, the invention has no substantive design and has no claim; but it can be said that the necessary preliminary preparation is made for the subsequent "automatic driving" of the bicycle.

Two groups of chain wheels on a motor shaft or a driving wheel shaft are respectively provided with unidirectional bearings or bicycle flywheels in opposite directions, and an electric/power generation automatic (or manual) switching device is arranged to prevent the phenomenon that the linear speeds of the chain wheels are inconsistent due to the inconsistent tooth numbers of the chain wheels at the two ends of the motor shaft and the driving wheel shaft, so that the 'internal consumption of mechanical energy' or even 'blockage' is caused; the precision, the efficiency, the noise index and the cost performance of the connecting chain wheel are relatively higher by using the one-way bearing and the specially manufactured groove key; the use of a bicycle flywheel standard is only applicable to the principle test stage.

The driving wheel in fig. 3 should allow axial flexible free movement of 0.5 to 2 cm to prevent wheel jamming due to wheel misalignment; the rubber wheel of the consumable part of the driving wheel is clamped by two steel discs with splined holes at the circle centers, is fixed by 4 countersunk head screws, is subjected to anti-loosening treatment and can be independently and conveniently replaced; the driving wheel rocker rotates by taking a motor shaft as an axis, is fixed on the outer ring of a bearing seat of a motor end cover in a rotating fit manner, is precise in fit and flexible in rotation.

The motor, the driving wheel, the chain sprocket, the clutch rocker arm and the base can be integrated into a whole, and the transmission assembly is provided with a corresponding wire plug and a clutch stay wire connector just like a transmission assembly of an automatic transmission car, so that the motor, the driving wheel, the chain sprocket, the clutch rocker arm and the base can be conveniently detached and assembled in seconds on a special support arranged on a front (or rear) wheel of a bicycle.

Two sets of drive of motor and driver and chain, sprocket, the one-way bearing of electricity generation all need to set up the chain cover and seal, both can ensure the people of rider, thing safety, can prevent again that silt from invading and increase the mechanical energy loss, can also collect the lubricating oil that splashes and flow back to the chain, keep efficient mechanical transmission.

The design of single-end output shaft can save a set of chain cover, and can share a set of electric/power generation automatic (or manual) switching device, thereby simplifying the process and reducing the manufacturing cost; in fact, the design of 'two ends are out of the shaft' is also possible; that is, although relatively costly, the advantages are: the gravity center of the device assembly which is counted to be several kilograms of weight is still close to the center line of the 'whole vehicle', and the dynamic balance of 'single vehicle' riding is not influenced.

The principle of the bi-directional drive is analyzed below with reference to fig. 4

When the motor-assisted bicycle runs, the motor shaft is driven to drive the wheel shaft to be driven:

the motor driving chain wheel is provided with a one-way bearing which is reversible and unsmooth (namely, the motor driving chain wheel can have anticlockwise angular displacement relative to a motor shaft, but can not have clockwise angular displacement);

the motor power generation chain wheel is provided with a one-way bearing which can be clockwise or irreversible (namely, the motor shaft can have clockwise angular displacement but can not have anticlockwise angular displacement);

the drive chain wheel of the driver has no one-way bearing;

the power generation chain wheel of the driver has no one-way bearing;

when the motor drags the driving wheel to run, the electric/power generation automatic (or manual) switching device is normally closed in an electric state, the motor shaft drags the motor power generation chain wheel through the driver power generation chain wheel in reverse, the rotating speed of the motor power generation chain wheel is larger than that of the motor driving chain wheel, and because the motor driving chain wheel and the power generation chain wheel are in the same direction and are provided with one-way bearings in opposite directions, even if a certain speed difference exists, the running cannot be influenced; because the motor/power generation automatic (or manual) switching device is normally closed in the 'power' state, the motor power generation chain wheel keeps idle in the same direction, and even though the 'friction force' is slight, the motor power generation automatic (or manual) switching device can also provide power for the motor driving chain wheel.

When the booster bicycle exceeds 25 km speed or braking, the driving wheel shaft and the driving motor shaft are driven:

the motor driving chain wheel is reversible and not reversible (namely, the motor driving chain wheel can have anticlockwise angular displacement relative to a motor shaft, but can not have clockwise angular displacement);

the motor power generation chain wheel can be clockwise or irreversible (namely, the clockwise angular displacement can be realized relative to a motor shaft, but the anticlockwise angular displacement can not be realized);

the drive chain wheel of the driver has no one-way bearing;

the power generation chain wheel of the driver has no one-way bearing;

when the motor controller detects that the electric vehicle exceeds 25 km in speed, the motor controller immediately commands the automatic (or manual) switching device of the electric/power generation to automatically switch to a power generation braking state (at the moment, the motor driving chain wheel keeps idling in the original direction), the driver drags the motor to accelerate and rotate to generate power, the rotating speed of the motor power generation chain wheel dragged by the driver power generation chain wheel is larger than that of the motor driving chain wheel, and the motor driving chain wheel and the power generation chain wheel are provided with one-way bearings in opposite directions, so that the electric vehicle can continuously run even if a certain speed difference exists, at the moment, the inertia resultant force of four chain wheels and two chains and the inertia force of the whole electric assisted bicycle (including people and goods) can be transmitted to the motor power generation chain wheel through the driving wheels, the chain wheels and the chain, the power assisting starting motor to generate power, and all positive energy, are utilized in time.

The specific implementation and the prospect show:

after patenting, standardization, trademark formation, archival design and internet management, the multifunctional and multipurpose shared bicycle, shared electric bicycle and shared combined 4-person resultant force + electric 4-wheel bicycle can be realized, wherein the attribute of a bicycle owner is unchanged, and the right of use is shared. Each vehicle has a unique factory number, so that a manager can conveniently build files for the vehicle owner and issue a 'running certificate'; the attribute of a buyer as an owner is always unchanged, and a 'shared single-car' operator plays a role of 'property management', can orderly put and set charging piles and access points on a building, a supermarket, an office, a school and the like of a city, shares data with property management chain operation on the points (each point unit is used for pulling customer resources, facilitating employees, owners and teachers of the unit, being reasonable and willing to cooperate and sharing profits), releases the data to a user mobile phone in real time, is convenient to access a single car or a combined car, is compatible with a 'stainless steel multifunctional environment-friendly shopping car', and needs to be self-provided, self-kept and not shared. The original stainless steel multifunctional environment-friendly shopping cart and the building block type environment-friendly shopping packaging box are not attractive, but are patented, branded and standardized in design, pushed to supermarkets and farmer markets to be shopping carts, pushed to living rooms to be simply deformed to be mobile tea tables, and placed in kitchens to be dining carts; when going out, the multifunctional bag can carry various packaging bags and even tableware, and can be carried on any group of shared bicycles updated according to the invention, so that the operability is realized for people to refuse to use disposable packages or tableware to fundamentally solve white pollution.

The invention also has an obvious functional bright spot: if the motor driving wheel assembly is designed and installed on the rear wheel, the bicycle can be changed into a multi-person multifunctional spinning bicycle which can build body and generate electricity and charge electricity as time and seconds (only the rear wheel needs to be supported off the ground); whether outdoor stormy rainstorm and snowfall, the user can not go out of home, or when the traffic of 'self-driving travel' is blocked, the user can stay in a camp in the open air, and inside and outside a tent in a scenic spot, along with wonderful music, and the user can unconsciously charge the electric power-assisted bicycle to full charge while enjoying the pleasure, building the body and entertainment; particularly, the method is very super-practical and practical in the popularization stage before the 'sharing' is realized.

The above-mentioned embodiments only express the embodiments of the present patent, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present patent. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept as defined by the appended claims. Therefore, the protection scope of this patent shall be subject to the appended claims.
