Description
Technical field
The utility model relates to a kind of electric lock head, relates in particular to a kind of little power consumption intelligent electric lock head.
Background technology
The mechanical lock of existing market and the application of electronic lock are all very extensive, and electronic lock reliably is subject to more and more users' welcome because of its security performance.Electronic lock is in the safety technological guard field, electronic password lock with anti-theft alarm function replaces traditional mechanical code lock, overcome that the mechanical code lock number of password is few, the shortcoming of poor safety performance, made coded lock technically or on performance, all greatly improve a step.
Existing electronic lock mostly is the coil type electromagnetic power and drives, and namely adopts the mode of unblanking to coil electricity generation magnetic force to realize unblanking, and magnetic force disappears and realizes shutting by spring reset behind the coil losing electricity.Because electromagnetic force can replace by the magnetic force of permanent magnet, so may be realized illegally unblanking by permanent magnet by the undesirable, reduced the security performance of electronic lock, key also is generally the modes such as IC-card, magnetic card, fingerprint and remote control simultaneously, complex structure, cost height are large with traditional habit difference.
In order to address this problem, adopting micro motor is a reasonable selection of electronic lock as driving power.But the existing electronic lock that drives with micro motor, battery is installed in employing in tapered end mode is circuit board and the motor power supplying in the tapered end, its defective is: circuit board needs the ceaselessly access information of detected electrons key, thus in running order for a long time, relatively waste electric energy; After use reached certain hour, the electric weight of battery can be finished, and need to again change battery, and is more loaded down with trivial details, and may can't realize unblanking to bring loss to the user when not enough because of electric weight; In addition, battery also can take than large space, and the volume of electric lock head is increased, and is unfavorable for installing, and especially is unfavorable for reequiping on existing mechanical lock basis.
The utility model content
The purpose of this utility model provides a kind of little power consumption intelligent electric lock head accurate, safe, low in energy consumption of controlling with regard to being in order to address the above problem.
In order to achieve the above object, the utility model has adopted following technical scheme:
Little power consumption intelligent electric lock head described in the utility model, comprise tapered end and place the interior tapered end core of described tapered end, described tapered end in-core is equipped with the circuit board with at least one key subregion and the micro motor that is electrically connected with described circuit board, on the described circuit board CPU is installed, the end that described tapered end core be used for to insert electron key is provided with the contact that is connected for the electron key contact, is electrically connected between the inner of described contact and the described circuit board; The inwall of described tapered end is provided with for the card door bolt is carried out spacing draw-in groove, and the clutch end of described micro motor is connected with described card door bolt by card door bolt drive unit.
In the said structure, cavity that be used for to insert key on the tapered end core with between the cavity of mounted motor tiny wire guide is only arranged, be mutual physical isolation between front cavity and the rear chamber.
By at the tapered end core contact being set, electronic unit when not having electron key to insert in the tapered end is in fully without electric idle state, automatic plugged when having electron key to insert, realize data transmission, check and to the driving of micromachine, under the prerequisite that satisfies accurately control, realize little power consumption electric drive function.
Particularly, described card door bolt drive unit can have various structures to realize that it drives function, and the below enumerates several concrete structures:
The first, described card door bolt drive unit is comprised of motor threaded shaft and lock core door bolt, is threaded connection between described motor threaded shaft and the described lock core door bolt, and described lock core door bolt is connected with described card door bolt.This mode directly is threaded connection the realization transmission, and is simple, direct; Its drive mechanism specifically can be: the center hole wall of described lock core door bolt is provided with screw thread, described motor threaded shaft places in the center pit of described lock core door bolt, this structure driven is reliable, also can adopt and in the center pit of motor threaded shaft, establish screw thread and be sleeved on the mode that lock core latches, also can adopt the mode of screw thread transmission directly arranged side by side between motor threaded shaft and the lock core door bolt.
On above-mentioned the first architecture basics, can also adopt following two kinds of different structures:
One, the center line of the center line of described motor threaded shaft and described tapered end core is parallel to each other, and described draw-in groove places described tapered end one end to keep to the side and locates and outer openings; Its two, the center line of described motor threaded shaft is mutually vertical with the center line of described tapered end core.In these two kinds of structures, the axis of the former micro motor is parallel with the axis of tapered end core, and the axis of the latter's micro motor is vertical with the axis of tapered end core, can both realize the purpose of unblanking and shutting.As preferably, the described lock core door bolt in these two kinds of structures is integrated with described card door bolt, not only firmly but also be convenient to processing.
Second, described card door bolt drive unit is the motor gear rotating shaft, described card door bolt is Linear rack card door bolt, described motor gear rotating shaft be connected by gear drive between described Linear rack card is fastened with a bolt or latch, the center line of the center line of described motor gear rotating shaft and described tapered end core is parallel to each other.This device has been realized the transformation of rotary power and straight line power by gear drive and has been changed the axis direction of power, can realize equally the purpose of unblanking and shutting.
Further, be provided with the mechanical type playback pellet supporting with key in the described tapered end.Mechanical type playback pellet is the same with the playback pellet of traditional mechanical lock, in the utility model, and the acting as of playback pellet: under original state, could insert and the taking-up key.
The beneficial effects of the utility model are:
The utlity model has control advantage accurate, safe, low in energy consumption, be specially:
1, the electronic unit in the tapered end described in the utility model has solved the problem of not opening and locking owing to the running down of battery of ordinary electronic lock by the Power supply on the electron key;
2, adopt micro motor as driver part, can not be subjected to the interference of permanent magnet, solved electromagnetic force and driven the low problem of security performance;
3, the working time of the micro motor on the tapered end core and circuit board is short, electric current is little, and power consumption is extremely low, environmental protection and energy saving;
4, owing to do not need battery, so the volume of tapered end is little, all parts all can realized at the standard machinery tapered end, can directly adopt the mode of replacing tapered end, and traditional mechanical lock is adapted as electronic lock or electromechanical lock, and safe class promotes greatly;
5, adopt the electronic identity verification mode between tapered end and the electron key, mutual opening rate is almost nil, and is safe;
6, circuit board can be preserved many group electron keys numberings and key pair, realizes many function of key operated tapered end.Under licensing status, the authority that can increase, delete certain key operated lock, electron key reproducible not under unauthorized state has also been stopped the possibility of technology unlocking.
