[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-5 This utility model provides a technical solution: a switching transmission structure for a logistics lock, wherein a drive motor 1 is fixedly installed inside the lock housing 5, and the drive motor 1 controls the rotation of the lock control component 3 through a transmission component. The rotation of the lock control component 3 is used to control the locking component 2 to move in opposite directions to lock or release the chain 4.

[0027] The transmission assembly includes a drive bevel gear 31, which is located at one end of the drive shaft of the drive motor 1. The drive bevel gear 31 meshes with a driven bevel gear 32, which is located on a rotating shaft 34. The rotating shaft 34 is rotatably located inside the lock housing 5. The lock control assembly 3 is located on one side of the rotating shaft 34. The lock control assembly 3 includes a lock disc 33, which includes symmetrically arranged arc-shaped locking parts 311 and symmetrically arranged releasing parts 312. The locking and releasing of the chain 4 are controlled by the alternating contact between the arc-shaped locking parts 311 and the releasing parts 312 with the locking assembly 2.

[0028] Specifically, the locking assembly 2 includes a first support frame 21 and a second support frame 23. The first support frame 21 and the second support frame 23 are symmetrically fixed inside the lock housing 5 on both sides of the lock disc 33. A first locking pin 22 is movably disposed inside the first support frame 21, and a second locking pin 24 is movably disposed inside the second support frame 23, which can engage and fix both ends of the lock chain 4. One end of the first locking pin 22 engages with a first locking groove 8, which is disposed on the first lock head 6. One end of the second locking pin 24 engages with a second locking groove 9, which is disposed on the second lock head 7. The first lock head 6 and the second lock head 7 are symmetrically disposed. The first lock pin 22 is placed at both ends of the chain 4, which improves the stability of fixing the first lock head 6 and the second lock head 7. The first lock pin 22 is sleeved with a first spring 25, and the second lock pin 24 is sleeved with a second spring 26, which can provide a return force for the first lock pin 22 and the second lock pin 24. One end of the first spring 25 is connected to the first support frame 21, and the other end of the first spring 25 is connected to the first lock pin 22. One end of the second spring 26 is connected to the second support frame 23, and the other end of the second spring 26 is connected to the second lock pin 24, which can drive the first lock pin 22 and the second lock pin 24 to move back to their original positions.

[0029] When the chain 4 is fixed, the first lock head 6 and the second lock head 7 at both ends of the chain 4 are inserted into the lock housing 5. When the first lock head 6 and the second lock head 7 are inserted, the first locking pin 22 and the second locking pin 24 are pushed to move within the first support frame 21 and the second support frame 23. The first locking pin 22 and the second locking pin 24 compress the first spring 25 and the second spring 26. When the first lock head 6 and the second lock head 7 are fully inserted into the lock housing 5, the first spring 25 and the second spring 26 drive the first locking pin 22 and the second locking pin 24 to engage in the first slot and the second slot, respectively. The drive motor 1 drives the drive bevel gear 31 to rotate, the drive bevel gear 31 drives the driven bevel gear 32 to rotate, the driven bevel gear 32 drives the rotating shaft 34 to rotate, the rotating shaft 34 drives the lock disc 33 to rotate, and the rotation of the lock disc 33 drives the two sets of When the arc-shaped locking part 311 rotates, and the arc-shaped locking part 311 is in contact with the first locking pin 22 and the second locking pin 24, the two sets of arc-shaped locking parts 311 fix the first locking pin 22 and the second locking pin 24, and then the first locking pin 22 and the second locking pin 24 fix the chain 4. When it is necessary to loosen the chain 4, the drive motor 1 drives the drive bevel gear 31 to rotate in the opposite direction, the drive bevel gear 31 drives the driven bevel gear 32 to rotate in the opposite direction, the driven bevel gear 32 drives the rotating shaft 34 to rotate in the opposite direction, the rotating shaft 34 drives the lock disc 33 to rotate in the opposite direction, and the arc-shaped locking part 311 separates from the first locking pin 22 and the second locking pin 24, so that the loosening part 312 is flush with the first locking pin 22 and the second locking pin 24. At this time, the first locking pin 22 and the second locking pin 24 are in the loosened state, and the chain 4 can be pulled out to complete the loosening of the chain 4.

[0030] Please see Figures 3-6 A detection component is also provided inside the lock housing 5 on the lower side of the lock disc 33. The detection component includes a PCB circuit board 51, which is located inside the lock housing 5 directly below the lock disc 33. A Hall sensor 52 is also provided on the PCB circuit board 51. The Hall sensor 52 is used to sense the magnetic field of the magnet 53. Specifically, the Hall sensor 52 is model SS441A. The magnets 53 are located on both sides of the bottom of the lock disc 33. Specifically, the two sets of magnets 53 are respectively placed at the bottom of the two sets of arc-shaped locking parts 311. The Hall sensor 52 can sense the magnetic field of the magnets 53 and indicate the rotation position of the lock disc 33.

[0031] When the chain 4 is in the loose state, the arc-shaped locking part 311 on the lock disc 33 is arranged in parallel with the two sets of Hall sensors 52. The magnet 53 corresponds to the Hall sensor 52. The Hall sensor 52 can detect the magnetic field signal of the magnet 53, and then the indicator light will light up with the corresponding color to indicate that the chain 4 is in the loose state.

[0032] When the chain 4 is locked, the arc-shaped locking part 311 on the lock disc 33 is in contact with the first locking pin 22 and the second locking pin 24. The magnet 53 is located on both sides of the Hall sensor 52. The Hall sensor 52 cannot detect the magnetic field signal, and the indicator light illuminates the corresponding color to indicate that the chain 4 is locked.

[0033] Furthermore, the PCB circuit board 51 is connected to the built-in power supply, which is fixed inside the lock housing 5. Specifically, the built-in power supply can be charged and is also connected to the indicator light on the lock housing 5, which can provide operating power for the components inside the device.

[0034] Furthermore, a wireless signal transmission module can be set on the PCB circuit board 51. The wireless signal transmission module connects to the remote control terminal via Bluetooth signal or wireless network signal. Specifically, the remote control terminal includes a mobile terminal or a PC terminal. Through the remote terminal, the opening and closing of the drive motor 1 can be controlled, thereby controlling the locking or unlocking of the chain 4.
