And it is connected in the secondary lock bolt structure 30 of shell 10.Main lock bolt structure 20 and 41 driving coupling of force piece being equipped with.Main lock bolt structure
20 by equipped with connecting rod 40 and secondary 30 driving coupling of lock bolt structure.Force piece 41 is motor, and motor drives main lock bolt structure 20
Locking is unlocked, and the action of main lock bolt structure 20 makes secondary lock bolt structure 30 link by connecting rod 40.
As shown in Figure 2 to Figure 3, main lock bolt structure 20 includes the main tongue block 21 being slidably connected with shell 10, with main tongue block 21
The main tongue driving lever 22 of driving coupling.The rotation of main tongue driving lever 22 and shell 10 couple, and the power intake of main tongue driving lever 22 with move
The power output end driving coupling of power part 41.Force piece 41 drives main tongue driving lever 22 to move, and then main tongue driving lever 22 drives main tongue
Block 21 moves, to realize that main tongue block 21 locks or unlocks.
Main 21 side of tongue block is equipped with the first detection piece 24, and stretching state or retracted mode are in detect main tongue block 21.And
And first detection piece 24 be optical coupled switch, by main tongue block 21 stretch out or retract condition conversion at electric signal.
Specifically, main tongue driving lever 22 by equipped with transmission component 23 and 41 driving coupling of force piece.Transmission component 23 wraps
The first bevel gear 231 for being fixed on 41 power output end of force piece is included, the second bevel gear 232 engaged with first bevel gear 231,
The driving gear 233 being fixedly connected with second bevel gear 232, and the driven gear 234 that is engaged with driving gear 233.Driven tooth
Wheel 234 is coaxially fixedly connected with main tongue driving lever 22, and is fixed on main 22 lower end of tongue driving lever.Driving gear 233 and second bevel gear
232 coaxial arrangements.
Preferably, main tongue block 21 is equipped with the first limiting slot 211.Driven gear 234 drives main tongue driving lever 22 in the first limit
211 pendulum motion of slot, main tongue driving lever 22 squeeze 211 inner wall of the first limiting slot, so that main tongue block 21 stretches out movement or retraction movement.
First limiting slot, 211 inner wall both sides are equipped with and recessed portion, and the shape of recessed portion matches with main 22 outer profile of tongue driving lever, when
For main tongue block 21 in stretching or retracted mode, main tongue driving lever 22 is only butted on recessed portion, and main tongue driving lever 22 is perpendicular to recessed portion,
Increase main tongue driving lever 22 to main 21 fixing of tongue block.
Wherein, main lock bolt structure 20 further includes the detection gear 235 engaged with driven gear 234 or driving gear 233.From
Moving gear 234 or driving gear 233 rotate, and detection gear 235 is driven to rotate, so as to be arranged the of 235 side of detection gear
Two detection pieces 236 detect detection 235 rotational angle of gear.Second detection piece 236 is optical coupled switch, will detect gear 235
Position relationship is converted to electric signal.
Preferably, elastic component (preferably torsional spring) is equipped between main tongue block 21 and shell 10 so that main tongue block 21 has
Elasticity, enhances that main tongue block 21 is flexible or the feel of retraction movement.Wherein, fixed with main tongue block 21 in the middle part of torsional spring, both ends fix with
On shell.
As shown in Figures 2 to 4, secondary lock bolt structure 30 includes the labella block 31 being slidably connected with shell 10, with labella block 31
First shifting block 32 of driving coupling.The rotation of first shifting block 32 is connected in shell 10, and with equipped with the first rotating bar 33 fix and join
It connects.First rotating bar 33 extends to 10 outside of shell, couples with the handle of locking device.When moving handle, 33 band of the first rotating bar
Dynamic first shifting block 32 movement, so that the first shifting block 32 driving labella block 31 is stretched out or retracted.Wherein, secondary lock bolt structure 30 further includes
Second shifting block 35, and the second shifting block 35 is fixedly connected with the second rotating bar 36 being equipped with.
Specifically, the first rotating bar 33 is fixedly connected with handle outdoors, the second rotating bar 36 is fixed with the handle in door
Connection.
With 32 first shifting block 32A with the same function of the first shifting block, wherein the first shifting block 32 and the first shifting block 32A mirrors
As setting.When the first shifting block 32 and the first shifting block 32A are symmetrical arranged, the overlapping of the two opposite site plays identical work(
Energy.First shifting block 32 is set and the first shifting block 32A is locking device in order to facilitate the installation of, can by locking device formal dress or anti-dress,
The first rotating bar 33 need to be only mounted on the first shifting block 32 or the first shifting block 32A at this time.
Wherein, the second shifting block 35 is arranged between the first shifting block 32 and the first shifting block 32A, the mutual self-movement of three.The
Two rotating bars 36 drive the rotation of the second shifting block 35, the first rotating bar 33 to drive the first shifting block 32 or the first shifting block 32A rotations.
Specifically, as shown in figure 8, the second rotating bar 36 includes the interior square bar portion 361 being fixedly connected with the second shifting block 35, wear
