Description

The automatically controlled lock of micro energy lose

Technical field

It the utility model is related to electric lockset technical field, more particularly to a kind of automatically controlled lock of micro energy lose.

Background technology

Electric lockset makes rapid progress, and its security and abundant function, makes mechanical lock sigh for being inferior.The intelligence of shared bicycle The dominance of energy lock, even more electronic lock.Using the mechanical puzzle lock for bicycle of fixed password, because of potential safety hazard, exit altogether Enjoy the arena of history of bicycle.However, traditional executing agency of electronic lock, using electromagnet or small machine acting driving, power consumption compared with Greatly.The power issue that it brings, turn into and hinder the wide variety of bottleneck of electronic lock, also annoying shared bicycle always.

At present, the power issue of bicycle intelligent bicycle lock is shared, it has to fill by generating or solar panel is ridden Electrolysis is determined, not only complicated, is easily damaged and is stolen, also cost is remained high.Generating of riding also makes to ride under comfort level Drop, Consumer's Experience are bad.Using battery powered smart electronicses lock, actual power restricted lifetime.The replacing of battery, for number Huge shared bicycle is measured, will be very large order.

In conventional method, executing agency is done using electromagnet, when locking, lock pin prevents dead bolt from moving；During unlocking, electromagnet Armature is dragged, lock pin is extracted, leaves blocked state.

Conventional method brings two problems：First, electromagnet extracts lock pin, it is necessary to do mechanical work, necessarily consumption is electric for acting Energy；Second, reliability and the power consumption size positive correlation of lockset locking.The reliability of so-called locking, after referring to that lockset is locked, External force resistance hits the probability for opening by mistake lock.Open by mistake that possibility is small, the reliability of locking is high.Obviously, the movement travel length of lock pin, it is quiet to rub Wiping power is big, and the reliability of locking is just high.But the movement travel length of lock pin, stiction is big, and acting is just more, it is desirable to which electromagnet exists Also greatly increased with bigger suction, power consumption during unlocking.In conventional method, reliability and the power saving of locking are mutual a pair The contradiction of restriction.

The content of the invention

The purpose of this utility model is that it can be significantly in view of the above-mentioned problems, design provides a kind of automatically controlled lock of micro energy lose Power consumption is reduced, makes the power-on time of battery, several times increase.And, it is ensured that the reliability of locking.

The purpose of this utility model is achieved through the following technical solutions：

A kind of automatically controlled lock of micro energy lose, it, which is formed, includes lock body and ring-shaped lock dead bolt, and electromagnet and with the linkage of its armature Lock pin, be provided with neck on ring-shaped lock dead bolt, provided with handle, lock pin may be inserted into neck under the promotion of lock pin back-moving spring, with Ring-shaped lock dead bolt is prevented to open, realization is locked, and one end connection dead bolt back-moving spring of the ring-shaped lock dead bolt, the other end of spring is being locked Fixed in vivo, its direction of pull is consistent with unlocking direction, after hand leaves handle and lock pin leaves neck, realizes and unlocks, described Neck is made up of at least two working faces, and one is to act on lock pin to stop stop that ring-shaped lock dead bolt moves towards unlocking direction Face, another is after locking, and ring-shaped lock dead bolt promotes lock pin to skid off the inclined-plane of neck when continuing motion towards direction of locking.The ring Shape dead bolt, under handle promotion, it can continue to move forward after locking, until the inclined-plane of the neck is lock pin pushing out card Groove.After the lock pin releases neck by neck inclined-plane, the armature and the static iron core that are linked with it form closed magnetic circuit.The lock pin With the linkage of armature, including it is directly connected to and is indirectly connected with by driving member, the driving member includes lever.The electromagnet by Static iron core, moving armature and coil, coil lead are formed, under closed magnetic circuit, the effect energy of electromagnetic force caused by coil electricity Overcome the effect of lock pin spring elastic force, maintain magnetic circuit closure.

Design of the present utility model：In conventional method, electromagnet makees unlocking mechanism, it is necessary to which electric energy makees machine when extracting lock pin Tool work(.During unlocking, lock pin is extracted manually if used instead, is done work without electric energy, while ensure that lock will not be opened by mistake manually, and make out Lock associates with whether being powered, it is possible to designs new micro energy lose unlocking mechanism.Particularly, in embodiment, manually It is that driving handle makes ring-shaped lock dead bolt be moved towards direction of locking, lock is surely not opened by mistake when helping lock pin acting.

Power saving principle：Locking state, in the presence of dead bolt back-moving spring pulling force, neck blocking surface presses tightly against lock Pin.If conventionally, electromagnet needs to overcome stiction to extract lock pin, and moves a trip, this is undoubtedly needed Want larger electrical power.And according to this design, as long as electromagnet holds armature under magnetic circuit closure state, it maintains electric current The simply part of operating current, therefore required electric current very little.On the other hand, battery is reduced with electricity, internal resistance increase, to negative The maximum current that carrying to provide diminishes, and acts unlocking mechanism as long as it can not provide enough operating currents, and battery is also just made It is useless, although it also has dump energy.Obviously, the small load of operating current, not only consumption electric energy is few, and the electricity of battery uses Must be more thorough, battery life is also just longer.

It is pointed out that the automatically controlled lock of micro energy lose, when electromagnet is powered, armature does not produce in the presence of electromagnetic force Raw mechanical movement, this is the difference basic with conventional automatically controlled unlocking mechanism of the invention.

The utility model has various deformation, but changes ten thousand times without leaving the original aim or stand, and all be unable to do without and replaces electromagnetic force to do mechanical work with hand, makes Electromagnetism iron circuit closes.

Because armature motion is by manually, its stroke is unrelated with electromagnetic attraction, and in principle, travel limit is not present in armature, The stiction for increasing lock pin and neck blocking surface nor affects on work.When needing to increase stroke, according to mechanical insight, Ke Yili With lever amplification stroke, that is to say, that use lever indirect drive between lock pin and armature.When needing to increase lock pin frictional force, lock Pin can use decorative pattern to increase coefficient of friction and enlarged contact areas with neck blocking surface.Their reliabilities to locking have Profit, and to power saving without disadvantage.

When lever indirect drive is used between lock pin and armature, lock pin forms the power arm of lever, and armature forms lever Resistance arm, they surround the fulcrum being fixed on lock body.

The inclined-plane of neck can also use curved surface, make latch pin ends slide when stress evenly.

Coil lead generally connects bluetooth, WiFi circuitry control panel, by low coverage or Remote, can also use cryptographic key Disk circuit controls, and this is mature technology, also has ready-made module, repeats no more.

Obviously, the utility model is not limited to shared bicycle lock, can also be widely used on other electric locksets, including Door lock, U-shape lock, cabinet lock, ordinary bicycle lock etc..

Beneficial effect

Using said structure, electromagnet need not consume electric energy and go extraction lock pin to do mechanical work, it is only necessary to the maintenance electricity of very little Just, power consumption declines to a great extent stream, realizes micro energy lose, can be powered using common batteries.The battery powered life-span can exceed altogether Enjoy bicycle and force retirement life, therefore battery need not be changed, it is non-maintaining to realize power supply, has saved lock cost and power supply cost. Also, for the motion due to armature by manually completing, stroke is unrelated with electromagnetic attraction, increases the friction of lock pin and neck blocking surface Power does not also increase power consumption, and the reliability of lockset locking is obviously improved, and has untied the original of power saving and the reliability locked therebetween Rationality contradiction.
