Description

The electron key system that is used for sulky vehicle
Technical field
This creation relates to a kind of electron key system that is used for sulky vehicle, relate in particular to a kind of control sulky vehicle in lock and opening between switch exempt from key system (keyless entry system).
Background technology
Recently international oil price soars, and the environmental protection problem also become the focus of international concern, so bicycle and man or electrically assisted bicycle are extended to short-range best vehicles gradually.Yet the employed relevant anti-theft device of described sulky vehicle still is confined to traditional mechanical lockset or tapered end, because described kind of mechanical lockset mostly is core, spring and megarchidium and forms, very easily suffer many intentionally personages with special instrument and unlocking technique with the illegal unlatching of lockset.Therefore need to use a kind of intelligent key system in a hurry, to strengthen the convenience of anti-theft feature and use.
The transmission system of above-mentioned electrically assisted bicycle comprises a high rotating speed electro-motor, and described motor can be assisted the rider to travel and pass through the road surface that resistance is difficult for overcoming as the source of auxiliary power.And, can improve outputting torsion relatively by this by the output speed reduction of reducing gear with motor.Motor power after the deceleration and rider's legpower can be combined by the power mixed organization, and are delivered to chain drum and drive electric bicycle and move ahead, and so can reach the purpose of saving muscle power.Electrically assisted bicycle can not only have the environmental protection and healthy characteristic of bicycle and man concurrently, more can be widely used in the bigger road surface of the outdoor leisure and the gradient.
Though the locomotive of traditional two-wheeled (machine power bicycle) does not have the advantage of environmental protection, because park suitable convenience and mobility strong, so still be the optimal selection of domestic short distance traffic instrument.Yet because of using similar mechanical lockset also to meet with above-mentioned same problem, and vibration is easy to generate wearing and tearing during because of action that plug is often arranged between key and core and driving, even can significantly reduce the safety of lockset.
At present existing on the market a kind of key system of exempting from that is used for four-wheel automobile, special-purpose remote-control key of people's portability or card form electron key, and in the permission range of receiving of automobile, get final product remote-control unlocking, or engine ignition is started.When people leave vehicle, can utilize equally described remote-control key will cut the engine and car door lock.Japanese patent laid-open 10-317754 communique has disclosed and has similarly exempted from key system, and it all is provided with transmitting antenna at four car doors, separately the locking of car controlling door.Yet the remote-control key in the above-mentioned routine techniques is active formula, promptly comprise a battery supply in order to active emitting radio wave signal to car door or automobile.Therefore, described remote-control key is subject to the size of described battery supply and weight and can't reduces its volume and weight and when running down of battery, also must disassemble described remote-control key and change battery.Simultaneously, described radio wave signal also has influence on the transmission of signal because of factor of environmental (for example weather or the obstruction between described remote-control key and reception antenna) and easily in order to have preferable signal receiving quality, reception antenna that the position is set is also very easily limited.
In sum, need a kind of electron key system of switching motion human oriented design on the market in a hurry and have low cost, the high advantages such as (promptly stable radio wave signal transmission qualities) of stability concurrently, make the price sulky vehicle lower also can use special spy's electron key system than automobile.
