The utility model relates to the technical field of bicycle electric unit structure improvement, which provides an electric bicycle booster comprising an electric friction wheel, a fixed stent, a battery, a spring and a control mechanism. The electric friction wheel in flexible connection through the fixed stent is installed beneath the centre shaft of the bicycle pedal, which is in direct contact with the rear wheel of the bicycle to drive. The utility model has the characteristics that the booster can be promoted in ordinary bicycles with convenient installation and low cost, which is energy saving, time saving and has no pollution to the environment.
Description
Technical field
The utility model belongs to the transportation and communication class, relates to the bicycle electric apparatus structure and improves technical field.
Technical background
At present, a variety of Electrical Bicycles are arranged on the market, great majority are special car load type Electrical Bicycles of manufacturing.Also there is minority on bicycle, to reequip, promptly in the middle of front-wheel or trailing wheel, adorns electric wheel hub, but lose in the market.The ubiquitous problem of above-mentioned Electrical Bicycle is complex structure, costs an arm and a leg, so the market sales volume is little.
Summary of the invention
The technical problems to be solved in the utility model is to have proposed a kind of bicycle electric servo-unit for overcoming the above-mentioned defective that exists.It mainly is made up of electronic friction wheel, fixed support, storage battery, spring and control mechanism.And electronic friction wheel is made up of electrical motor, drive belt or chain, friction wheel, the overriding clutch and the rotary support that are contained in the friction wheel.Electronic friction wheel flexibly connects and is installed in bicycle pedals axis below with rotary support and fixed support, and electronic friction wheel can rotate around the fixed support point of connection.Spring one end is fixed on the cycle rack, and the other end connects an end of friction wheel.Friction wheel is by the spring force pressure of the spring trailing wheel of always driving a vehicle in the electronic friction wheel.When electrical motor rotates, make friction wheel from rotation by drive belt or chain, thereby drive the bicycle rear rotation, bicycle is advanced.Control mechanism is made up of handgrip, steel wire noose, switch and electric wire.Steel wire noose one end connects handgrip, and the other end connects electrical motor one end of electronic friction wheel.The point of connection of motor terminal should be with above-mentioned spring and friction wheel end point of connection symmetry and in the both sides of rotary support in steel wire noose and the electronic friction wheel.When handgrip is exerted oneself, when power during, promote by electrical motor one end of steel wire noose with electronic friction wheel greater than spring force, the rotary support clickwise of electronic friction wheel descends the friction wheel of the other end, breaks away from bicycle rear.When unclamping handgrip, because the spring tension of spring with electronic friction wheel left-hand revolution, makes friction wheel press bicycle rear, friction wheel from rotation drives the bicycle rear rotation and advances when energising.Electric wire is used to connect switch, storage battery and electrical motor.Switch is used for the opening and closing electrical motor.
The utility model bicycle electric servo-unit is that a kind of additional device is installed on ordinary bicycle, install additional conveniently, low price, for leaning on bicycle as walking-replacing tool, and distance is far away, wanting to save the people of muscle power and time, is very practical, makes ordinary bicycle have the function of Electrical Bicycle.
The power that the utility model is used is electricity, is provided by storage battery, and evening or down time can charge, repeated use, and owing to electricity consumption is used as power, non-environmental-pollution, because electricity is arranged, and also can throw light on night, utilization is worthy to be popularized.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model friction wheel (1-3) and overriding clutch (1-4) combination scheme drawing.
In Fig. 1 and Fig. 2, the electronic friction wheel of 1-flexibly connects with rotary support (1-5) and fixed support (2); The 1-1-electrical motor; 1-2-drive belt or chain; The 1-3-friction wheel, outer wheel surface is made uneven, so that strengthen friction drag; The 1-4-overriding clutch is contained in the friction wheel (1-3); The 1-5-rotary support; The 2-fixed support is installed in bicycle pedals main shaft below and flexibly connects with rotary support (1-5); The 3-storage battery; The 4-spring, an end is connected with cycle rack, and the other end is connected with friction wheel (1-3) end of electronic friction wheel (1); The 5-control mechanism; The 5-1-handgrip is contained in the bicycle handle bar; 5-2-steel wire noose, an end is connected with handgrip (5-1); The other end is connected with electrical motor (1-1) end of electronic friction wheel (1).
The specific embodiment
Below in conjunction with Fig. 1 and Fig. 2 the utility model specific implementation process is described:
1, by Fig. 2 overriding clutch (1-4) is contained in the friction wheel (1-3) earlier, then electrical motor (1-1), drive belt (1-2), friction wheel (1-3) and rotary support (1-5) is assembled into electronic friction wheel (1).
2, earlier fixed support (2) is installed in the foot-operated axis of ordinary bicycle below.Then electronic friction wheel (1) is flexibly connected by rotary support (1-5) and fixed support (2).
3, earlier spring (4) one ends are connected with cycle rack, the rotary support (1-5) that the other end and the close friction wheel (1-3) in the electronic friction wheel (1) are held is connected then.
4, earlier handgrip (5-1) is installed in the bicycle handle bar, steel wire noose (5-2) end is connected with handgrip (5-1), then steel wire noose (5-2) other end is connected with electrical motor (1-1) end of electronic friction wheel (1).
5, storage battery (2) is fixed on the cycle rack, again switch is fixed on Handlebar of bicycle (5-1) other (not marking among the figure), with electric wire switch, storage battery (3) and electrical motor (1-1) are connected (not marking among the figure) on demand then.
Below in conjunction with Fig. 1, Fig. 2 the utility model specific operation process is described:
1, open switch, electrical motor (1-1) started rotation, by drive belt (1-2) with friction wheel (1-3) driven rotary, because the spring force of spring (4) makes friction wheel (1-3) be close to bicycle rear.Since friction wheel (1-3) thus male and fomale(M﹠F) drive bicycle rear rotation bicycle and advance.
2, when bicycle is worked by the utility model Electric booster, with handgrip (5-1) firmly, when this power during greater than the spring force of spring (4), by steel wire noose (5-2) electrical motor (1-1) end of electronic friction wheel (1) is mentioned, make electronic friction wheel (1) clickwise, friction wheel (1-3) descends and the disengaging bicycle rear in the then electronic friction wheel (1).
3, off switch, Electric booster quits work, electrical motor (1-1) and friction wheel (1-3) all quit work, but when bicycle moves on owing to inertia, to drive friction wheel (1-3) rotation, but owing in the friction wheel (1-3) overriding clutch (1-4) is arranged, make drive belt (1-2) motionless, electrical motor (1-1) is rotated.
