DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] Example

[0027] See also Figure 1-Figure 8 , as shown in the figure, is an intelligent horseshoe lock, including a housing 100, a lock ring 200, a lock gate 300, a key unlocking part 400, and a motor unlocking part 500. The lock ring 200 is provided with a lock groove 201 for the end of the lock gate 300 to be inserted. The lock ring 200 is a prior art and will not be elaborated in detail here. The lock gate 300 is movably arranged in the housing 100. The output end of the motor unlocking part 500 and the output end of the key unlocking part 400 are both connected to the lock gate 300 transmission matching. It is worth noting that it also includes a limiting mechanism for limiting the retreat of the lock gate 300 in the locked state, and the limiting mechanism includes a pushing portion 501 arranged on the motor unlocking part 500 to press the lock gate 300. The pushing portion 501 presses the lock gate 300 when the lock gate 300 is in the locked state, so that the lock gate 300 is not easily withdrawn from the lock groove 201 of the lock ring 200 under the action of external force. The pushing portion 501 is driven by the motor 502 to disengage from the lock gate 300 when the lock gate 300 is in the unlocked state.

[0028] In this embodiment, the transmission cooperation structure between the motor unlocking part 500 and the lock gate 300 is that the pushing part 501 is arranged at the output end 503 of the motor unlocking part 500. The so-called output end 503 is the output shaft of the motor 502 or the final output shaft of the reduction mechanism connected to the motor output shaft or a part connected to the output shaft. In this embodiment, the pushing part 501 is a wheel-shaped part arranged on the output shaft. The wheel-shaped part is provided with an eccentric part which is not coaxial with the output shaft. The eccentric part extends to one side of the lock gate. The eccentric part is the pushing part 501. The lock gate 300 is provided with a groove 301. The pushing part 501 extends into the groove 301 and moves therein. The transmission cooperation between the two is achieved by pushing the inner wall of the groove 301 when the pushing part 501 moves in the groove 301.

[0029] The present embodiment controls the position of the push part 501 by the following means, and also includes a control switch 600 for positioning the active position of the push part 501. A push block 504 is provided at the output end of the motor unlocking part 500. The push block 504 is provided on the outer edge of the wheel-shaped part, and the push block 504 rotates with the wheel-shaped part. The control switch 600 is provided within the movement track of the push block 504. When the motor 502 rotates forward or reversely, the push block 504 can touch the control switch 600. 00, when the motor unlocking part 500 is unlocked, the top block 504 moves to touch the control switch No. 1 600, and the push part 501 is then in the middle position of the groove 301, so that the lock gate 300 has a self-moving gap; when the motor unlocking part 500 is locked, the top block moves in the opposite direction to touch the control switch No. 1 600, and the push part 501 is then in the bottom position of the groove 301 and presses the lower wall of the groove 301 to limit the lock gate 300 from being separated from the lock groove 201 of the lock ring 200. That is, the push portion 501 and the top block 504 form a set angle, which should ensure that when the top block 504 rotates to one side to touch the control switch No. 1 600, the push portion 501 is at the bottom of the groove 301 of the lock gate 300, and when the top block 504 rotates in the opposite direction to touch the control switch No. 1 600, the push portion 501 is in the middle position of the groove of the lock gate 300. It is also necessary to grasp the installation position of the control switch No. 1 600 so that the top block 504 can trigger the control switch No. 1 600 in both directions. The second control switch 700 is also included. A trigger arm 302 is provided on the lock gate 300. The second control switch 700 is provided within the range of the activity track of the trigger arm 302. When the lock gate 300 is locked, the trigger arm 302 touches the second control switch 700. The second control switch 700 connects the motor circuit and controls the motor 502 to reverse, until the top block 504 reversely touches the first control switch 600. The second control switch 700 is provided so that when the lock gate 300 is automatically locked, the push portion 501 of the motor control part can automatically move to press the lock gate 300, ensuring that each time it is locked, it can have a high anti-violence effect. The first control switch 600 and the second control switch 700 described in this embodiment are installed inside the housing 100.

[0030] In order to enable the lock gate 300 to automatically insert into the lock groove 201 of the lock ring 200 when the lock ring 200 is locked, a spring 800 is provided between the lock gate 300 and the housing 100 in this embodiment to push the lock gate 300 toward the side of the lock ring 200. When the lock ring 200 is locked, the spring 800 pushes the lock gate 300 to insert into the lock ring 200. At that time, the trigger arm 302 of the lock gate 300 can trigger the No. 2 control switch 700 to realize the operation of the motor unlocking part and control the pushing part 501 to press the lock gate 300.

[0031] In order to open the lock ring 200 when there is no electricity, the key unlocking part 400 is specially designed in this embodiment. Specifically, the key unlocking part 400 is designed to include a movable push rod 401 movably connected to the lock gate 300, a rotating block 402 rotatably arranged in the lock gate 300, and a transmission member 404 for transmitting power between the rotating block 402 and the lock core 403, wherein the end of the movable push rod 401 can be movably inserted into the lock groove 201 of the lock ring 200, the transmission member 404 is fixed or snap-fitted with the lock core 403, and an elastic member 405 for pressing the movable push rod 401 toward one side of the rotating block 402 is provided between the movable push rod 401 and the lock gate 300. In this embodiment, the lock gate 300 comprises two parts that are assembled and connected to each other, and a space for parts to be installed and moved is provided inside the lock gate 300, wherein the rotating block 402, the movable push rod 401 and the elastic member 405 are all provided in the space. When the lock gate 300 is pressed by the push portion 501 of the motor control part (i.e., in the locked state), a matching key is inserted and the key is rotated, and the transmission member 404 and the rotating block 402 are driven to rotate by the rotation of the lock cylinder 403, so that the space in the movable direction of the movable push rod 401 in the lock gate 300 becomes larger, and the movable push rod 401 retracts under the action of the elastic member 405 so that the movable push rod 401 escapes from the lock gate 300 to unlock. A sliding matching structure is provided between the transmission member 404 and the rotating block 402 and is arranged parallel to the movement direction of the lock gate 300. The sliding matching structure is arranged so that when the transmission member 404 rotates, the rotating block 402 rotates with the transmission member 404; when the lock gate 300 moves as a whole, the rotating block 402 slides relative to the transmission member 404. In this embodiment, a slide groove 4041 parallel to the movement direction of the lock is provided at the end of the transmission member 404, and a slider 4021 extending into the slide groove 4041 is provided on the rotating block 402. The slider 4021 and the rotating block 402 are an integrated structure.

[0032] In this embodiment, the rotating block 402 is provided with outer edges of different spacings at least along the rotation point of the transmission member 404 (such as the rotating block is designed as a cam structure), namely, a near outer edge and a far outer edge, wherein when the transmission member 404 drives the rotating block 402 to rotate, the outer edge of the rotating block 402 abuts against the movable top rod 401, and when the near outer edge and the far outer edge switch to each other, the rotating block 402 pushes the movable top rod 401 to perform telescopic movement. When the electronic lock cannot be opened due to some factors or the lock gate 300 is stuck and cannot be moved due to some reasons, it can still be unlocked by a key.
