The limiting control 26 is used to control the extension and retraction of the limiting plate 27.

[0019] As a further provision of the above scheme, the combination lock 2 includes a housing 21 with a lock hole 22 and a cover 23 that fastens to the housing 21. The latch assembly 25 includes a bolt 251, a lock plate 252 and a latch return spring 253. The lock plate 252 is provided with a spring groove 254 for the placement of the latch return spring 253. The cover 23 is also provided with an abutment groove 255 for cooperating with the lock plate 252 to accommodate the latch return spring 253.

[0020] As a further provision of the above scheme, the control component 28 also includes a battery 282 for the motor component 281, a keypad 232, and an electronic control circuit board for the motor component 281. The output end of the motor component 281 is connected to a cam drive 283, and the mechanical lock cylinder component 24 is provided with a lock pin 285 with a top spring 284 relative to the cam drive 283.

[0021] As a further arrangement of the above-mentioned scheme, the limiting control 26 further comprises a control lock pushing piece 261, two sets of limiting grooves 262 are arranged on the control lock pushing piece 261, and a limiting pin 263 and a limiting spring 264 are arranged in a matched mode, and the control lock pushing piece 261 is further provided with an extension connecting plate 265, the end of the extension connecting plate 265 is arranged at a position between the limiting connecting plate 27 and the bolt assembly 25, and the limiting connecting plate 27 is pushed away from the bolt assembly 25 by the control lock pushing piece 261.

[0022] As a further arrangement of the above-mentioned scheme, the limiting connecting plate 27 comprises a limiting clamping part 271 arranged to be telescopic relative to the bolt assembly 25, the front end of the limiting clamping part 271 is provided with a plane, and is arranged at a position between the two sets of bolt assemblies 25, and a pushing spring 272 is arranged at the other end of the limiting clamping part 271.

[0023] The working principle of the intelligent U-shaped lock is as follows:

[0024] Referring to the ordinary password U-shaped lock of the prior art, the correct password is input through the password keyboard 232 exposed on the password lock piece 2, the bolt assembly 25 of the mechanical lock core assembly 24 is driven to retract relative to the lock slot 11 by the internal motor assembly 281 after the password verification by the control assembly 28, and the locking is released, so that unlocking is realized.

[0025] It is worth noting that the intelligent U-shaped lock of the embodiment, on the basis of the above, adopts a cam driving piece 283 arranged at the output end of the motor assembly 281, when the motor assembly 281 is started to unlock, the rotating cam driving piece 283 rotates to push the lock column 285 to slide and compress the top spring 284, and at the same time, the slot opening opposite to the lock column 285 on the limiting control 26 is escaped, so that the locking and limiting of the control lock pushing piece 261 are released, and at this time, the password lock piece 2 is in an unlocked state, the user pushes the control lock pushing piece 261, and the limiting connecting plate 27 is moved away from the bolt assembly 25 through the extension connecting plate 265, so that the clamping of the two sets of bolt assemblies 25 is released, and based on the arrangement of the bolt tongue 251 of the bolt assembly 25, the bolt tongue 251 slides along the inner side of the U-shaped lock beam 1, and the password lock piece 2 is escaped from the U-shaped lock beam 1.

[0026] Further, the control lock pushing piece 261 of the embodiment is further provided with two sets of limiting grooves 262, and the limiting pin 263 and the limiting spring 264 are arranged on the housing piece 21, the rear end of the limiting pin 263 is pressed by the limiting spring 264, and the limiting pin 263 is elastically pushed to slide and switch between the two sets of limiting grooves 262, and the limiting pin 263 is clamped in one of the two sets of limiting grooves 262 by the limiting spring 264 at the end of the unlocking and locking strokes of the control lock pushing piece 261, so that the limiting of the control lock pushing piece 261 is formed.

[0027] Further, the extension connecting plate 265 of the control lock pushing piece 261 in the embodiment is located between the limiting connecting plate 27 and the bolt assembly 25, that is, when the control lock pushing piece 261 moves away from the bolt assembly 25, the extension connecting plate 265 can move with the limiting connecting plate 27, otherwise, based on the limiting pin 263 clamping the control lock pushing piece 261, when the control lock pushing piece 261 does not move, the limiting connecting plate 27 cannot move towards the bolt assembly 25, while the control lock pushing piece 261 is not affected by the limiting connecting plate 27, and then it can realize that the limiting control 26 can be reset to the locked state when the bolt assembly 25 and the lock slot 11 are not opposite, while the limiting connecting plate 27 is based on the front end limiting clamping part 271 of the push spring 272 abutting against the two lock plates 252, and based on the elastic driving of the lock plate 252 and the column tongue 251 by the bolt reset spring 253, the lock plate 252 and the column tongue 251 are adhered to the inner side of the U-shaped lock beam 1 and the lock slot 11, after the lock plate 252 and the column tongue 251 are clamped into the lock slot 11 next time, the two lock plates 252 are relatively far away based on the bolt reset spring 253, thereby forming a space larger than the width of the limiting clamping part 271, the limiting clamping part 271 is clamped into the retraction locking of the lock plate 252, and the password lock 2 is locked to the U-shaped lock beam 1.

[0028] Compared with the prior art, the limiting control 26 in the embodiment is set by the separation of the extension connecting plate 265 and the limiting connecting plate 27 and the positional relationship of the two, which can realize that the control lock pushing piece 261 is not forced to be linked with the limiting connecting plate 27 from unlocking to locking, thereby realizing that the control lock pushing piece 261 can be pushed to lock in any state of the lock plate 252 and the lock slot 11 not corresponding to each other when the user locks the door; secondly, based on the cooperation of the limiting slot 262, the limiting pin 263 and the limiting spring 264, the position of the limiting connecting plate 27 is controlled by the control lock pushing piece 261, thereby realizing that the control lock pushing piece 261 is not reset and locked when it is pushed in the unlocking state, that is, the bolt assembly 25 cannot be locked to the lock slot 11, which is convenient for the user to use.

[0029] Obviously, those skilled in the art can make various modifications and changes to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and changes of the present application belong to the scope of the present application and equivalent technology, the present application also intends to include these modifications and changes.
