Specific embodiment
The utility model is further described with reference to the accompanying drawings and embodiments:
Embodiment one: a kind of electronic lock structure in the present embodiment applies to lock construction on key case.Referring to Fig. 1~
Shown in 9, including shell 1, it is set to the cavity 2 that storing is used in the shell 1,1 front of shell is equipped with defeated for password
The front panel 3 entered, the inside of the front panel 3 are equipped with latch mechanism 4 and control circuit, and the latch mechanism 4 is electronic lock, including driving
Circuit, strike plate 5 and the mounting assembly 6 being connect with strike plate 5,
The driving circuit is used to receive the unlocking information of control circuit, controls the effect to the strike plate 5；
The mounting assembly 6 includes lock support 7, the shaft 8 on lock support 7 and the latch hook spring in shaft 8
9, the strike plate 5 is sheathed in the shaft 8, and the effect end of the latch hook spring 9 is connect with the strike plate 5, the lock
Tongue piece 5 is equipped with lock hook slot 10, and the sealed pin 11 on the lock hook slot 10 and the shell 1 cooperates；
The strike plate 5 is cooperated by the driving circuit and the latch hook spring 9, is obtained centered on the shaft 8
The freedom degree of the positive and negative rotation of axis makes the lock hook slot 10 constitute occlusion with the sealed pin 11 or separate two states.
As shown in Fig. 7,9, the driving circuit includes battery 12, control circuit and motor 13, the control circuit control
The rotation of the motor 13 is made, the main shaft 14 that the motor 13 exports is equipped with a cam structure, the shaft in the mounting assembly 6
8 are arranged in parallel with the main shaft 14, and the outer edge surface of the strike plate 5 is connect with the cam structure.In the present embodiment, described convex
Wheel construction is that 14 side of main shaft is equipped with a slant cutting edge 15, and the outer edge surface of the strike plate 5 is matched with the slant cutting edge 15
It closes.Using slant cutting edge 15 to the center of circle distance be less than radius, formed cam effect, strike plate 5 by with different distance outer rim
The cooperation in face is realized from a kind of state to the switching of another state.Specific fit system is as follows are as follows:
Sealed recess 16, unlocking locating slot 17 and retention bead 18, institute are successively arranged on the outer edge surface of the strike plate 5
It states sealed recess 16 to cooperate with 14 outer edge surface of main shaft, the unlocking locating slot 17 cooperates with the slant cutting edge 15, and institute
The intersection that retention bead 18 is butted on the slant cutting edge 15 and 14 outer edge surface of main shaft is stated, the strike plate 5 is made to be defined in unlocking
State；The effect end of the latch hook spring 9 is buckled in the retention bead 18, makes strike plate 5 centered on shaft 8 to the master
The rotation of 14 side of axis.
When main shaft 14 rotates forward (rotating clockwise), slant cutting edge 15 is diverted strike plate 5, and strike plate 5 is in latch hook spring 9
Active force under, rotated to 14 side of main shaft, 16 turn to unlocking locating slot 17 from sealed recess, up to being butted in retention bead 18,
As shown in figure 9, in this case, the lock hook slot 10 on strike plate 5 is detached from sealed pin 11, as shown in figure 8, before shell 1
Plate 3 automatically opens under gravity.
Opposite, before being turned off when panel 3, main shaft 14 and strike plate 5 is needed to reset respectively.The main shaft 14 of the motor 13
On be arranged with a reset spring 19, so that main shaft 14 is rotated backward and (is rotated counterclockwise).Meanwhile the lock hook slot on the strike plate 5
10 are made of two sides cell wall and inner concave arc surface, and side cell wall, which extends outwardly, constitutes sealed briquetting 20, and the sealed pin 11 acts on
In reversely rotating, the strike plate 5 on the sealed briquetting 20, the latch hook spring 9, the lock hook slot 10 and the lock are stretched
Dowel pin nail 11 forms occlusive state.
Before being turned off when panel 3, then front panel 3 is closed, due to the sealed briquetting on sealed 11 urges locking bolt piece 5 of pin
20, so that strike plate 5 is switched to sealed recess 16, and active force of the main shaft 14 in reset spring 19 at this time from unlocking locating slot 17
Under, it reversely rotates, downward 14 outer edge surface of main shaft of slant cutting edge 15 is butted in the sealed recess 16 of strike plate 5, as shown in fig. 7, lock
Lock tongue piece 5 can not turn round again, at this time lock hook slot 10 and sealed 11 occlusive state of pin, as shown in fig. 6, before realizing shell 1
Panel 3 is sealed.
In occlusion with the switching for separating two states, what is utilized is the mutual cooperation of latch hook spring 9 Yu reset spring 19,
To make only to need to rotate using dry cell 12 (direct current) drive motor 13 to a direction in driving circuit, without examining
Consider the driving force resetted, simplifies driving, be easily installed, structure is also more small and exquisite, compact.
As shown in Figure 2,3, the outside of the front panel 3 is equipped with protective cover 21, and described 21 one end of protective cover passes through pin
Axis is rotationally connected with the bottom surface of the shell 1, and the other end is connected together by the top surface of buckle and the shell 1.Realization pair
The dustproof and waterproof of 1 front panel 3 of shell is protected, and protective cover 21 is opened, and inputs unlocking cipher.1 back side of shell is equipped with several
A fixing threaded hole 22, the shell 1, which is bolted, to be installed on a side wall.
Shown in institute Fig. 4,1 inner wall of shell is equipped with LED illumination lamp 23 and key ring 24, which prolongs
Shi Kaiguan is connect with the control circuit, and when 1 front panel of shell is opened, the LED illumination lamp 23 is lighted, and is opened by delay
It is automatically closed after closing delay.
It is additionally provided with emergency socket on the outside of shell 1, when 12 not enough power supply of battery, external power supply can be inserted by emergency socket
(such as existing mobile power source), can emergency starting open shell 1, the battery 12 more renewed is extensive after inputting proper password
Multiple normal use.
Embodiment two, a kind of electronic lock structure, in the present embodiment, structure are substantially similar to embodiment one, difference
It is: may be selected to control the positive and negative electrode access of motor by control circuit using access alternating current in the driving circuit, from
And realize the forward and backward of main shaft, therefore, in the present embodiment, main shaft is resetted without using reset spring.The program is not strictly according to the facts
Apply that one structure of example is simple, and the dual spring of embodiment one is more highly preferred to.
