It should be noted that, in the initial state, that is, when the lock body 200 is not inserted into the bolt 100, the card body 24221 is in the first position, that is, the lock tongue 241 extends into the receiving cavity 2421a, so that a malicious person who returns a toothpick or a card or other non-adapted object can be prevented from inserting into the lock body 200.

In an embodiment, referring to fig. 5, the latch tongue 241 is a ball, the card body 24221 is provided with a slide 24221A abutted to the ball, and the slide 24221A includes a straight section 24221A1 and a hemispherical section 24221A 2; when the ball abuts against the straight line part 24221a1, the ball extends into the accommodating cavity 2421 a; when the ball abuts against the hemispherical section 24221a2, the ball retracts from the accommodating cavity 2421 a. Specifically, hemispherical section 24221a2 is located at one end of linear section 24221a1, hemispherical section 24221a2 is proximate to socket 231 of lock body 200, and linear section 24221a1 is distal from socket 231 of lock body 200. The hemispherical section 24221a2 is a hemispherical groove and the ball bearings may be partially received in the hemispherical section 24221a 2. When the slide 24221A slides to the hemispherical section 24221A2 opposite to the lock hole 2421b, the ball bearings can be accommodated in the hemispherical section 24221A2, the ball bearings retract from the accommodating cavity 2421A, and the card body 24221 is in the second position; when the slide 24221A slides to the position where the straight line part 24221A1 is opposite to the locking hole 2421b, the ball is pressed by the straight line part 24221A1, and the ball extends into the holding cavity 2421A, and the card main body 24221 is at the first position. The locking mode that ball and slide 24221A matched with is adopted to this embodiment, and simple structure is convenient, and it is smooth and easy to slide, and the condition that can not appear blocking leads to unable returning, improves the reliability of returning.

The through hole 2421c is disposed in the direction of inserting the keyhole seat 2421 into the latch 100, and the through hole 2421c is communicated with the accommodating cavity 2421 a. The through hole 2421c of the push rod 221 extends into the receiving cavity 2421a, and the neck 222 is located outside the keyhole seat 2421. The neck 222 abuts against the pushing sheet 24222 of the driving card 2422, so that when the pushing rod 221 is pushed by the bolt 100 in the inserting direction, the pushing sheet 24222 is driven to move in the inserting direction. The card body 24221 connected with the pushing piece 24222 is slidably connected to the keyhole seat 2421, so that the card body 24221 is driven to slide in the inserting direction when the pushing piece 24222 moves in the inserting direction. Since the card body 24221 is in the first position in the initial state, the latch 100 is inserted into the pushing rod 221 to drive the card body 24221 to move in the inserting direction, and the card body 24221 is driven to move to the second position, and the latch tongue 241 retracts from the receiving cavity 2421 a.

Referring to fig. 7, the inclined block 2424 is disposed on the lock case 23, the inclined block 2424 has an inclined surface, and during the movement of the neck 222, the neck 222 abuts against the inclined surface of the inclined block 2424, the inclined surface jacks up the neck 222, so that the neck 222 is separated from the abutment with the pushing piece 24222, and the pushing piece 24222 cannot move further in the insertion direction.

With continued reference to fig. 4, the unlock mechanism 25 is connected to the driver blade 2423, and the driver blade 2423 is slidably connected to the card body 24221 while a spring member 2425 is provided to abut between the driver blade 2423 and the card body 24221. Specifically, a slide rail 24221B is disposed on a side of the card main body 24221 facing away from the keyhole seat 2421, and a slide block is disposed on the driving plate 2423, and the slide block and the slide rail 24221B cooperate to realize sliding. The slide block of the driving plate 2423 is composed of left and right slide pieces 24232, the left and right slide pieces 24232 enclose a space for accommodating the elastic element 2425, the elastic element 2425 is accommodated in the space, and a gap for embedding the slide rail 24221B is left between the left and right slide pieces 24232. During assembly, the elastic part 2425 is located at a position separated and separated from the middle of the slide rail 24221B and is accommodated in a space surrounded by the left and right slide pieces 24232. Thereby, both ends of the elastic member 2425 abut against the driving member and the card body 24221, respectively, so that the elastic member 2425 can provide elastic force in the sliding direction of the card body 24221. It is understood that the connection structure of the driving plate 2423, the card body 24221 and the elastic member 2425 may be other ways as long as it is possible to realize that the elastic member 2425 provides elastic force in the sliding direction of the card body 24221. Since the driving sheet 2423 is connected to the unlocking mechanism 25, when the unlocking mechanism 25 is not unlocked, the driving sheet 2423 remains relatively fixed, so that the card body 24221 can generate a restoring force under the elastic force of the elastic element 2425 to reset the card body 24221 when the card body 24221 slides relative to the keyhole seat 2421.

The driving process of the lock bolt 100 of the lock body 200 is described below with reference to fig. 6-10:

s1: referring to fig. 6 and 7 and fig. 8, the plug 100 is inserted into the receiving cavity 2421a from the socket 231, the first conductive contact 12 of the plug 100 abuts against the push rod 221 penetrating through the through hole 2421c, and the push rod 221 is pushed towards the insertion direction of the plug 100. When the push rod 221 moves in the direction of inserting the bolt 100, the neck 222 of the push rod 221 abuts against the pushing piece 24222 of the driving card 2422, so that the neck 222 can drive the push rod 221 to move in the direction of inserting the bolt 100. At this time, the card body 24221 connected to the pushing piece 24222 moves in the same direction (i.e. the same direction as the insertion direction of the latch 100), so that the card body 24221 moves from the first position (in the initial state) to the second position to drive the latch tongue 241 to retract from the receiving cavity 2421a, and the latch 100 can be inserted smoothly without being blocked by the latch tongue 241.

S2: referring to fig. 8 and 9 and fig. 10, during the process that the neck portion 222 pushes the pushing piece 24222 to move towards the insertion direction of the bolt 100, the inclined block 2424 arranged on the lock shell 23 is met by the neck portion 222, the inclined surface of the inclined block 2424 is abutted by the neck portion 222, the inclined surface pushes the neck portion 222 upwards, so that the neck portion 222 is disengaged from the pushing piece 24222, and finally, the card body 24221 connected with the pushing piece 24222 does not move towards the insertion direction of the bolt 100 any more. At this time, since the elastic element 2425 can apply an elastic force in the sliding direction of the card body 24221, the card body 24221 can return to the second position and rebound under the action of the elastic force, and slide back to the first position, so as to drive the latch tongue 241 to extend into the receiving cavity 2421a, thereby locking the latch 100.

The process of bolt 100 inserting locking has been accomplished from this, only can accomplish the locking to bolt 100 through mechanical transmission structure, need not to go up the action of electric detection or response, and the operating mode of locking is convenient, and the time spent of locking is short, and user experience is good.

In the embodiment, the motor 251 is connected to the second circuit board 21, the motor 251 controls the motor 251 to operate according to the verification result given by the second circuit board 21, and when the verification result is failure, the motor 251 is driven to operate, and the motor 251 drives the driving sheet 2423 to move in a direction opposite to the insertion direction of the bolt 100. Specifically, the clamping portion 24231 on the driving plate 2423 is clamped between two adjacent circles of threads of the output shaft thread 252, so that when the output shaft rotates, the clamping portion 24231 can be driven to move along the axial direction of the output shaft by the rotation of the thread 252, wherein the axial direction of the output shaft is arranged in the insertion direction of the bolt 100. Therefore, when the motor 251 is driven, the driving piece 2423 moves in a direction opposite to the insertion direction of the bolt 100 to drive the card body 24221 to move in the same direction opposite to the insertion direction of the bolt 100, so that the card body 24221 moves from the first position to the second position, the latch tongue 241 retracts from the receiving cavity 2421a, and the lock on the bolt 100 is released. After the motor 251 unlocks, the driving sheet 2423 is driven to reset, the driving sheet 2423 drives the card main body 24221 to return to the first position, and the lock tongue 241 extends into the accommodating cavity 2421a again.
