The specific embodiment
Below with reference to each embodiment shown in the drawings the utility model is described in detail.But these embodiments do not limit the utility model, and the conversion on the structure that those of ordinary skill in the art makes according to these embodiments, method or the function all is included in the protection domain of the present utility model.
Please refer to Fig. 1 to a preferred embodiments that Figure 9 shows that the utility model electronic password lock 100.Described electronic password lock 100 comprise lock body 1 and with the lock nut 2 of lock body 1 phase snap close.The motor 12 that described lock body 1 comprises lower house 11, is installed on the control mainboard of lower house 11 inside, is connected with the control mainboard, be installed on the motor 12 and towards described lock nut 2 directions stretch out lower house 11 dead bolt 14, connect and control mainboard and the battery of motor 12 and the keyboard 15 that is installed on lower house 11 outsides and is connected with described control mainboard.Described lock nut 2 comprises upper shell 21 and the loam cake 22 that hides upper shell 21.At motor described in the utility model 12, dead bolt 14 and the lock nut 2 common electronic lock driving mechanisms that form the utility model electronic password lock.
Please extremely shown in Figure 5 in conjunction with Fig. 1, described lower house 11 comprises box body 111 and the lower cover 112 of covering above box body 111.Described electronic password lock 100 also comprises the fastening shaft sleeve 13 that connects described motor 12 and dead bolt 14.Described fastening shaft sleeve 13 1 end surfaces are provided with equally distributed some spherical salient points 131.It is four at spherical salient point 131 described in the utility model.Described spherical salient point 131 matches with the inner surface of described lower cover 112 with in order to reduce the skew in lock body 1 rotation process.Described fastening shaft sleeve 13 also is one of the element of the electronic lock driving mechanism of the utility model electronic password lock.Be provided with to carry out microcontroller and the real-time timepiece chip RTC that dynamic password calculates on the described control mainboard.Be provided with 0 to 9 10 numeric keys and three functions key on the described keyboard 15.Described three functions key is respectively: blocking wedge Lock, cancel key ESC and enter key Enter.Described electronic password lock comprises that also connection control mainboard also outwards is exposed to the indicator lamp 151 on the described keyboard 15, and the externally fed interface that is connected with described battery.At some in particular cases, for example self-discharge of battery rate out of the ordinary is higher, and perhaps this battery is worked the several years, causes battery electric power to be not enough to provide motor 12 work, and can provide electric power to described control mainboard and motor 12 this moment by described externally fed interface.
Please extremely shown in Figure 7 in conjunction with Fig. 5, described dead bolt 14 is T-shaped design and upwards stretches out described lower house 11.Described dead bolt 14 be provided be fixed in the described fastening shaft sleeve 13 with the locking bar 141 that connects motor 12 and be positioned at locking bar 141 tops and with locking bar 141 vertically disposed tapered ends 142.
Please in conjunction with Fig. 5 to shown in Figure 9, described upper shell 21 is provided with the jam plate 211 that is horizontally disposed with to lock mutually with described dead bolt 14.Described jam plate 211 is provided with and described dead bolt 14 phase snap closes or the lockhole 212 that separates.Described lockhole 212 comprise the disengaging hole 213 of running through up and down the strip that described jam plate 211 passes for described tapered end 142 and be connected with described disengaging hole 213 for described tapered end 142 stretch into and therein rotation to the lock hole 214 of described jam plate clasp about in the of 211.Described lock hole 214 is rounded shape design roughly, and the equal in length in the diameter of described lock hole 214 and described disengaging hole 213.Described jam plate 211 is provided with along described lock hole 214 diametric(al)s and protrudes in opposite directions a pair of limited block 215 in the described lock hole 214, in order to limit described tapered end 142 anglecs of rotation.
It is in the same plane that described limited block 215 is the inner surface in fan shape, one side surface and described disengaging hole 213, in order to tapered end 142 rotation to break away from hole 213 when parallel limitation lock head 142 continue rotation, thereby so that tapered end 142 smoothly disengaging in described disengaging hole 213, and then unblank.The opposite side surface of described limited block 214 is perpendicular with the inner surface in described disengaging hole 213, in order to stretch in the described lock hole 214 at tapered end 142 and to carry out the anglec of rotation of locking when rotation limitation lock head 142, in the utility model, this anglec of rotation is 90 degree, when being locking, described tapered end 142 is perpendicular with disengaging hole 213, thereby realizes preferably locking snap close effect; Also only need 90-degree rotation to can rotate to break away from hole 213 parallel when in like manner, unblanking to rotate; Be that open locking only needs dead bolt 14 rotations 1/4th circles in the utility model, and motor 12 only drives dead bolt 14 rotations so that load is very light, so so that the utility model electronic password lock 100 is not only simple in structure, and it can effectively reduce power consumption, and then the stand-by time that effectively prolongs battery.Described tapered end 142 tops are formed with and are obliquely installed to guide the guiding face 1421 that described tapered end 142 penetrates described disengaging hole.
When the utility model electronic password lock 100 is in the lock state, the user is at described keyboard 15 input dynamic passwords and after pressing the input "enter" key", after the control mainboard judges that by its autonomous high security AES that has arranged input is legal, drive motors 12 rotates described dead bolt 14 lockset position of coupler that parallels with described disengaging hole 213 to tapered end 142, then allow motor 12 quit work, this moment, the user can with breaking away from lock nut 2 self-locking bodies 1, namely open electronic password lock 100.And when the utility model electronic password lock 100 is under the unlocking condition and needs locking, lock nut 2 can be covered to lock body 1, after pressing simultaneously the blocking wedge Lock on the keyboard 15, control mainboard drive motors 12 drives tapered end 142 and is inverted to the position that intersects vertically with described disengaging hole 213, then allow motor 12 quit work, can finish block action.
Got by above, the utility model electronic password lock 100 is by adopting the control mainboard to detect keyboard 15 input passwords, then control motor 12 and drive dead bolt 14 unlatching and closure to realize electronic password lock 100 with lock nut 2 phase snap closes or disengaging, thus on the one hand so that the user without carrying keys, unauthorized person is difficult for opening on the other hand, safety factor is higher, and the utility model electronic password lock 100 overall structures are simple, and convenient manufacturing and power consumption are lower.
Be to be understood that, although this manual is described according to embodiment, but be not that each embodiment only comprises an independently technical scheme, this narrating mode of manual only is for clarity sake, those skilled in the art should make manual as a whole, technical scheme in each embodiment also can through appropriate combination, form other embodiments that it will be appreciated by those skilled in the art that.
Above listed a series of detailed description only is specifying for feasibility embodiment of the present utility model; they are not to limit protection domain of the present utility model, allly do not break away from equivalent embodiment or the change that the utility model skill spirit does and all should be included within the protection domain of the present utility model.
