29, the second cylinder body 33, first stretches out oil circuit 30, second and stretches out oil circuit 31 and the second retraction composition of oil circuit 34, and second piston 18 exists
In second cylinder body 33, first piston 21 is in the first cylinder body 29, and impeller 36 is in the blade wheel chamber 35-3 of hydraulic pump 35, hydraulic shell
22 are made of hydraulic pump 35, the first cylinder body 29 and the second cylinder body 33, there is the first retraction grease chamber 29-1 and in the first cylinder body 29
One stretches out grease chamber 29-2, has the second retraction grease chamber 33-1 and second to stretch out grease chamber 33-2 in the second cylinder body 33, and hydraulic pump 35 is external
There are two interface, one is to retract interface 35-1, the other is stretching out interface 35-2, hydraulic shell 22 is fixed on lock body shell 16
On.
The mode of communicating of the retraction oil circuit 27 of the retraction interface 35-1 of hydraulic pump 35 and first and the second retraction oil circuit 34 has two
Kind, a kind of mode is serial communication, refers to that retracting interface 35-1 connection second retracts one end of oil circuit 34, second retracts oil circuit 34
The other end connection second retract grease chamber 33-1, first retract 27 one end of oil circuit connection second retract grease chamber 33-1, the other end connect
Logical first retracts grease chamber 29-1, and another way is parallel communication, and the one end and first for referring to the first retraction oil circuit 27 retract oil
Room 29-1 connection, the other end are connected to interface 35-1 is retracted, and one end of the second retraction oil circuit 34 retracts grease chamber 33-1 with second and connects
Logical, the other end is connected to interface 35-1 is retracted.
The mode of communicating of the stretching oil circuit 30 of the stretching interface 35-2 of hydraulic pump 35 and first and the second stretching oil circuit 31 has two
Kind, a kind of mode is serial communication, refers to and stretches out one end that oil circuit 31 is stretched out in interface 35-2 connection second, and second stretches out oil circuit 31
The other end connection second stretch out grease chamber 33-2, the other end with second stretching grease chamber 33-2 be connected to, another way be parallel connection connect
It is logical, refer to that interface 35-2 is stretched out in one end connection of the second stretching oil circuit 31, grease chamber 33-2 is stretched out in other end connection second, and first stretches
30 one end of vent line is connected to the first stretching grease chamber 29-2, and the other end is connected to interface 35-2 is stretched out.
The working principle of hydraulic device is：The linkage impeller 36 of controlled motor 23 rotates, using the rotation of impeller 36, by first
The hydraulic oil retracted in grease chamber 29-1 retracts oil circuit 27, hydraulic pump blade wheel chamber 35-3, the first stretching entrance of oil circuit 30 by first
First stretches out in grease chamber 29-2, and first piston 21 stretches out the first cylinder body 29, while the second hydraulic oil retracted in grease chamber 33-1 passes through
It crosses the second retraction oil circuit 34, hydraulic pump blade wheel chamber 35-3, the second stretching oil circuit 31 to enter second and stretch out in grease chamber 33-2, second is living
Plug 18 stretches out the second cylinder body 33, changes the rotation direction of controlled motor 23, first piston 21 can be retracted 29 He of the first cylinder body
Second piston 18 retracts the second cylinder body 33.
The working principle of automatically controlled unlocking is：Smart lock controls circuit control controlled motor 23 and rotates, and controlled motor 23 links
Impeller 36 rotate, first piston 21 start retract the first cylinder body 29, while second piston 18 start retract the second cylinder body 33, second
Piston 18 controls the controlled portion on oblique lock tongue control piece 17 using the controlling position of end, and oblique lock tongue 2 is retracted lock panel
1, while first piston 21 controls the controlled portion on main lock tongue disjunctor 8 using the controlling position 21-1 of end, and main lock tongue 9 is contracted
Lock panel 1 is returned, controlled motor 23 stops operating.
The effect of locking piece 26 is：After first piston 21 retracts the first cylinder body 29, locking piece 26 is in locking piece spring 28
Under the action of, by the end lock of first piston 21, oblique lock tongue 2 only is controlled in second piston 18 and all stretches out lock panel 1
Later, the end of second piston 18 starts to control locking piece 26, and first piston 21 could stretch out the first cylinder body 29, if latch-up-free
Part 26 and locking piece spring 28, first piston 21 and second piston 18 will stretch out the first cylinder body 29 and the second cylinder body 33 simultaneously.
The effect of limit switch 32 is：It is intelligence when first piston 21 and second piston 18 are all stretched out or are fully retracted into
Energy lock control circuit provides a switching signal, controls the working condition of controlled motor 23.
According to sets requirement, there are three types of modes for automatically controlled locking, and first way is in setting time after unlocking, tiltedly
Lock tongue 2 stretches out lock panel 1 first, and the main locking of lock tongue 9 needs to wait input locking instruction again could lock, the second way
It is that oblique lock tongue 2 stretches out after lock panel 1, main lock tongue 9 is directly locked without waiting for input locking instruction, the third mode is nothing
Locking piece 26 and locking piece spring 28, oblique lock tongue 2 and main lock tongue 9 will extend and retract lock panel 1 simultaneously.
Lock core 10 unlock working principle be：Shift fork on rotation lock core 10 stirs clutch for clutch control part 5 first, controls clutch
Clutch for clutch control position 5-1 on control piece 5 is no longer contacted with the controlling position 21-1 of 21 end of first piston, will be led using shift fork
Lock tongue 9 and oblique lock tongue 2 retract lock panel 1.
Hydraulic package directly controls main lock tongue 9 and refers to the activity direction and main lock tongue 9 for controlling the first piston 21 of main lock tongue 9
The activity direction extended and retracted is identical, indirectly controls main lock tongue 9 and refers to the activity direction for controlling the first piston 21 of main lock tongue 9
The activity direction extended and retracted with main lock tongue 9 is not identical.
The present invention controls main lock tongue 9 using electric control hydraulic device and oblique lock tongue 2 extends and retracts lock panel 1, retains door
Internal handle controls main lock tongue 9 and oblique lock tongue 2 retracts the mode of lock panel 1, is particularly suitable for smart lock, advantage is inside lock body
Structure is simple, and without electric control clutch component outdoors, the noise that no machine driving generates can be realized mute locking and unlocking.
