Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-4 The utility model provides a technical solution: a matching structure of a passive lock core and an electronic key, comprising:

[0027] A lock body 1 and a passive lock core 2, and a key head 3 adapted to the passive lock core 2;

[0028] A key frame 4 installed at the bottom of the key head 3, and a button part and a fingerprint recognition part installed on the surface of the key frame 4;

[0029] A sliding mechanism 5 is provided on the top of the key frame 4 for protecting the key part and the fingerprint recognition part;

[0030] The sliding mechanism 5 includes a protective sliding frame 51, a mounting column 52, a ball cage groove 53, a ball 54 and a guide groove 55. Guide grooves 55 are provided on both sides of the key frame 4. The surface of the key frame 4 is provided with a protective sliding frame 51, and two mounting columns 52 are embedded on both sides of the inner wall of the protective sliding frame 51. Ball cage grooves 53 for rolling of the ball 54 are provided inside the mounting columns 52, and one side of the ball 54 is adapted to the guide groove 55 on the surface of the key frame 4.

[0031] A transparent plate 6 is embedded in the surface of the protective sliding frame 51, and an indicator light 7 is installed on the surface of the key frame 4;

[0032] In this embodiment, the lock body 1 contains an intelligent chip and adopts a passive design. It does not require power supply and communication wiring. When the key head 3 on the active key frame 4 contacts the passive lock core 2, the power supply and unlocking password signals on the active key frame 4 are transmitted to the built-in microcomputer. If the two passwords match, the lock is unlocked. Fingerprints and buttons are used for adjustment. When not in use, the sliding protective slide frame 51 blocks and protects the button part to avoid accidental touch or impact. When the protective slide frame 51 slides on the key frame 4, the protective slide frame 51 will drive the ball 54 in the internal mounting column 52 to slide on the guide groove 55, thereby enhancing the stability of the movement of the protective slide frame 51.

[0033] Two magnetic blocks 8 are fixedly installed on both sides of the protective sliding frame 51, and the protective sliding frame 51 is set as a metal frame;

[0034] Specifically, a magnetic block 8 is disposed on the surface of the key frame 4, and the protective sliding frame 51 is configured as a metal frame, which can be adsorbed with the magnetic block 8, shielding the key portion and having a certain adsorption force, thereby preventing the protective sliding frame 51 from shaking.

[0035] In order to facilitate the separation of the key frame 4 and the protective back plate 9 , the inside of the key frame 4 is inspected, wherein the key frame 4 is powered by a built-in battery, and a protective back plate 9 is installed on the back of the key frame 4 .

[0036] A protective member 10 for preventing dust from the passive lock core 2 is installed at the bottom of the lock body 1. The protective member 10 includes a snap-on protrusion 101, a protective baffle 102 and a rotating seat 103. The rotating seat 103 is fixedly installed at the bottom of the lock body 1. The protective baffle 102 is rotatably installed on the surface of the rotating seat 103. A circular groove portion for snapping the snap-on protrusion 101 is opened on the surface of the protective baffle 102.

[0037] Furthermore, when the lock needs to be unlocked, the protective baffle 102 is removed from the snap-fitting protrusion 101, and the protective baffle 102 is rotated to the side, exposing the passive lock core 2 for use. Similarly, the protective baffle 102 is rotated to snap-fit ​​and fix the circular groove on the surface of the protective baffle 102 to the snap-fitting protrusion 101, thereby completing the shielding protection of the lock core.

[0038] The protective baffle 102 is configured as a glue layer plate, and the protective baffle 102 is arranged at the bottom of the passive lock core 2;

[0039] Specifically, the protective baffle 102 is a glue-layer plate, which facilitates the swing adjustment of the protective baffle 102 .

[0040] In order to facilitate hanging and carrying of the key frame 4 , a hook frame 11 is integrally formed at the bottom of the key frame 4 .

[0041] The contact column inside the passive lock core 2 is matched with the contact groove on the surface of the key head 3, and the passive lock core 2 and the key head 3 are both arranged in an equilateral triangle;

[0042] It is worth noting that the passive lock core 2 and the key head 3 are both set to be regular triangles, and the triangular design has excellent stability. Due to the structural characteristics of the triangle, the lock head and the lock core can evenly disperse the pressure when subjected to force, thereby enhancing its overall pressure resistance, so that it can maintain higher structural stability when subjected to external force impact or illegal opening attempts.

[0043] The lock body 1 of the device contains an intelligent chip and adopts a passive design. It does not require power supply and communication wiring. When the key head 3 on the active key frame 4 contacts the passive lock core 2, the power supply and unlocking password signals on the active key frame 4 are transmitted to the built-in microcomputer. If the two passwords match, the lock is unlocked. Fingerprints and buttons are used for adjustment. When not in use, the sliding protective slide frame 51 blocks and protects the button part to avoid accidental touch or impact. When the protective slide frame 51 slides on the key frame 4, the protective slide frame 51 will drive the ball 54 in the internal mounting column 52 to slide on the guide groove 55, thereby enhancing the stability of the movement of the protective slide frame 51.

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
