For the convenience of narration, the orientation described below is defined as follows: the up-down, left-right, front-back directions described below are consistent with the up-down, left-right, front-back directions of the projection relationship of Figure 1 itself. An intelligent luggage lock of the present utility model includes a lock head and a lock seat. The lock head and the lock seat are respectively installed at the opening and closing part of the luggage and fixed. After the lock head and the lock seat are unlocked, the opening and closing function of the luggage can be realized. The lock seat is installed on the luggage body, and the lock head is installed on the luggage flap.
[0025] Advantageously, the lock head includes a plug-in block 12, the lock seat includes a body 19, a slot 11 is provided in the body 19, the plug-in block 12 is inserted into the slot 11, a telescopic block 42 that elastically moves back and forth is provided in the body 19, an inner groove 51 is provided in the plug-in block 12. After the plug-in block 12 is inserted into the body 19 and abuts against the telescopic block 42, the telescopic block 42 is first pushed and moved, and then when the inner groove 51 is opposite to the telescopic block 42, the telescopic block 42 is spring reset and snapped into the inner groove 51.
[0026] Advantageously, two mating blocks 33 are provided at the bottom of the plug-in block 12, a bifurcated connecting block 54 is provided on one side of the plug-in block 12, and an inner cavity 53 is provided in the bifurcated connecting block 54.
[0027] Advantageously, a plurality of mounting holes 52 are provided in the plug-in block 12, and the mounting holes 52 are used to fix the lock head to the turning surface of the luggage.
[0028] Advantageously, a side groove 13 is provided in the slot 11, and the bifurcated connecting block 54 is slidably connected with the side groove 13.
[0029] Advantageously, a plurality of guide rods 44 are provided in the body 19, a plurality of spring placement holes 43 are provided in the telescopic block 42, the guide rods 44 are slidably connected with the spring placement holes 43, and a compression spring 45 is elastically connected in the guide rods 44 and the spring placement holes 43, so that the telescopic block 42 elastically expands and contracts relative to the guide rods 44.
[0030] Advantageously, two abutting grooves 32 are provided in the telescopic block 42. After the abutting grooves 32 abut against the mating blocks 33, the telescopic block 42 can elastically slide toward the guide rod 44. After the mating blocks 33 are disengaged from the abutting grooves 32, the mating blocks 33 abut against the main body of the telescopic block 42. It is not until the plug-in block 12 moves to a position where the inner groove 51 is opposite to the telescopic block 42 that the telescopic block 42 can be reset and snap-fitted with the inner groove 51.
[0031] Advantageously, a plurality of bottom plates 36 are provided in the body 19, a top plate 34 is provided on the top side of the bottom plates 36, and a plurality of elastic springs 35 are elastically provided between the top plate 34 and the bottom plates 36. After the mating blocks 33 are inserted into the body 19, the mating blocks 33 abut against the top plate 34 and compress the elastic springs 35.
[0032] Beneficially, a slide rail 37 is provided inside the body 19. An installation plate 39 is provided on one side of the slide rail 37. A micro motor 41 is provided on one side of the installation plate 39. A threaded shaft 61 is power-connected to one side of the micro motor 41. A push plate 31 is slidably arranged on the outer surface of the slide rail 37. The push plate 31 is in threaded engagement with the threaded shaft 61. After the micro motor 41 operates, it drives the push plate 31 to move towards the telescopic block 42, so that the push plate 31 passes through the inner cavity 53 and abuts against the telescopic block 42, extruding the telescopic block 42 towards the guide rod 44, so that the telescopic block 42 is disengaged from the clamping connection with the plug-in block 12. Under the elastic action of the elastic spring 35, the matching block 33 and the plug-in block 12 are pushed upwards, facilitating the separation of the lock head and the lock seat by the user, and then the user can manually open the luggage case to achieve the unlocking function.
[0033] Beneficially, a rechargeable battery 21 is provided inside the body 19. An NFC induction module 23 is also provided inside the body 19. A single-chip microcomputer module 24 is provided on the top of the NFC induction module 23. An induction groove 22 located inside the body 19 is provided on one side of the NFC induction module 23.

The single-chip microcomputer module 24 is electrically connected to the NFC induction module 23, the micro motor 41 and the proximity switch 38. When the telescopic block 42 is inserted into the plug-in block 12 and fixed, if the user wants to unlock, the NFC card is inserted into the induction groove 22. Through the induction of the NFC induction module 23, after the NFC induction module 23 is electrically connected to the single-chip microcomputer module 24, the single-chip microcomputer module 24 controls the micro motor 41 to operate, so that the micro motor 41 drives the push plate 31 to slide along the slide rail 37 through the threaded shaft 61, and the push plate 31 pushes the telescopic block 42 until the push plate 31 abuts against the proximity switch 38. The proximity switch 38 triggers an electrical signal to the single-chip microcomputer module 24, and the single-chip microcomputer module 24 stops the micro motor 41. At this time, the plug-in block 12 can achieve the unlocking function; a pressure sensor can be provided in the top plate 34. After the pressure sensor in the top plate 34 fails to read data, that is, when the matching block 33 is disengaged from the top plate 34, the single-chip microcomputer module 24 controls the micro motor 41 to rotate in the reverse direction, driving the push plate 31 to reset to the initial state. At this time, after a process is completed, the user takes out the NFC card from the induction groove 22.
[0034] The pressure sensor is electrically connected to the rechargeable battery 21 and the single-chip microcomputer module 24.
[0035] A USB charging port or other charging ports of other specifications are provided at the bottom of the rechargeable battery 21 for easy charging.
[0036] After the operator plugs the plug-in block 12 into the slot 11 and inserts it into the body 19 again, the mating block 33 first abuts against the abutting groove 32, causing the telescopic block 42 to elastically slide towards the guide rod 44. Then, the mating block 33 abuts against the top plate 34, causing the top plate 34 to compress the elastic spring 35. Then, until the telescopic block 42 elastically resets and engages with the inner groove 51 in the plug-in block 12, the fixing function of the lock head and the lock seat can be achieved.
[0037] Beneficially, a plurality of inner holes 16 are provided in the body 19. An outer hole 17 is provided on one side of the side plate 14 and is located on one side of the inner hole 16. A cover plate 15 is provided on one side of the body 19. A plurality of fixing cylinders 18 are provided on one side of the cover plate 15. The fixing cylinders 18 are inserted into the inner holes 16. By providing fasteners, such as screws, etc. in the inner holes 16 and the outer holes 17, the screws are threadedly engaged with the inside of the fixing cylinders 18, and the screw nut part is located in the outer hole 17, thereby connecting and fixing the cover plate 15 to the body 19.
[0038] When installing the lock seat, the side plate 14 is used to install it at the end of the box body of the luggage, and the installation hole 52 in the plug-in block 12 is used to install the lock head at the end of the flip cover of the luggage.
[0039] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any change or replacement that is thought of without creative labor should be covered within the protection scope of the present utility model; therefore, the protection scope of the present utility model should be subject to the protection scope defined by the claims.
