The electronic lock 100 includes a first locking component 10 and a second locking component 20 . The first locking component 10 and the second locking component 20 are respectively disposed on the first to-be-closed component 200 and the second to-be-locked component 300. The input device 30 is disposed on any one of the first to-be-locked component 200 and the second to-be-locked component 300. The first to-be-locked component 200 and the second to-be-closed component 300 may be two doors of a pair of open cabinet doors, respectively, or may be a large door and a door frame, respectively. The first locking component 10 and the second locking component 20 are in a locked state and an unlocked state, so that the first to-be-closed component 200 and the second to-be-locked component 300 are locked together or separated.

Please refer to 2 for a schematic diagram of the internal structure of the electronic lock 100. The first lock member 10 includes a receiving groove 11 , a tongue portion 12 , and an elastic member 13 that are opened on the back surface. The tongue portion 12 and the elastic member 13 are received in the receiving groove 11 . The receiving slot 11 has an opening 111. The elastic member 13 is located between the latching portion 12 and the side wall of the receiving slot 11 for limiting the latching portion 12 to the receiving slot 11 when no external force is applied. It does not protrude from the opening 111. The tongue portion 12 is made of a magnetic material.

The second locking component 20 includes a receiving cavity 21, an electromagnet 22, and a control circuit board 23. When the first to-be-locked component 200 and the second to-be-closed component 300 are closed, the position of the receiving cavity 21 is opposite to the position of the opening 111. The electromagnet 22 is disposed at the bottom of the receiving cavity 21 of the second locking component 20 .

Please refer to FIG. 3 to FIG. 4 together. FIG. 3 is a front view of the electronic lock 100. The electronic lock 100 further includes an input device 30 for inputting an input information by a user. The input device 30 can be fixed to the outer surface of the first to-be-closed component 200 or the second to-be-closed component 300. As shown in FIG. 4, the control circuit board 23 is electrically connected to the input device 30 and the electromagnet 22 for comparing with a predetermined information when receiving input information input by the input device 30, and comparing the input. When the information matches the predetermined information, the power supply to the electromagnet 22 is controlled such that the electromagnet 22 generates a magnetic force to attract the locking tongue portion 12 to protrude from the opening 111 against the elastic force of the elastic member 13 and is received in the second lock. In the receiving cavity 21 of the fitting 20. Therefore, the first to-be-locked component 200 and the second to-be-locked component 300 are locked together by the cooperation of the locking tongue portion 12 and the receiving cavity 21 of the second locking component 20.

Specifically, as shown in FIG. 4, the control circuit board 23 includes a controller 231, a power source 232, and a path switch 233 mounted thereon. The path switch 233 is connected between the power source 232 and the electromagnet 22. The controller 231 is connected to the path switch 233 and the input device 30. The controller 231 is configured to control the path switch 233 to be turned on when the input information generated by the input device 30 is received, and compare the input information with the predetermined information, so that the power source 232 supplies power to the electromagnet 22. At this time, the electromagnet 22 is energized to generate a magnetic force to attract the tongue portion 12 to protrude from the opening 111 and protrude into the receiving cavity 21. Obviously, the controller 231 controls the path switch 233 to be turned off when the input information generated by the input device 30 is not received, or when the input information does not match the predetermined information, so that the power source 232 does not supply power to the electromagnet 22. At this time, the electromagnet 22 does not generate a magnetic force. Due to the elastic force of the elastic member 13, the tongue portion 12 is driven to move into the receiving groove 11, without exposing the opening 111 of the receiving groove 11 and not being accommodated in the second portion. The receiving cavity 21 of the locking member 20 is in the receiving cavity 21. At this time, the first to-be-locked component 200 and the second to-be-closed component 300 are separable.

The accommodating slot 11 further includes a first receiving slot 112 and a second receiving slot 113. The first receiving slot 112 is a rectangular recess having a long side and a narrow side. The second receiving slot 113 is a horizontal through slot extending from the middle of the first vertical side 1121 of the first receiving slot 112 adjacent to the opening 111 and communicating with the first receiving slot 112 and the opening 111. The first receiving groove 112 and the second receiving groove 113 form a flat "convex" shape. The tongue portion 12 includes a vertical strip 121 and a horizontal strip 122 extending from a central portion of the vertical strip 121 perpendicular to the vertical strip 121. The width of the vertical strip 121 is smaller than the width of the lateral side of the first receiving slot 112, and the length is substantially equal to the vertical side of the second receiving slot 113. The horizontal strip 122 is received in the second receiving groove 113 through the first receiving groove 112 . The horizontal strip 122 and the vertical strip 121 may be integrally formed, or may be locked together by screws or the like.

The number of the elastic members 13 is two, and the two elastic members 13 are respectively disposed on two sides of the horizontal strip 122, and each elastic member 13 is located between the vertical strip 121 and the first vertical side 1121 for When there is no external force, an elastic force is applied to the vertical strip 121 of the tongue portion 12 such that the vertical strip 121 of the tongue portion 12 moves away from the opening 111, so that the horizontal strip 122 is completely accommodated in the second The opening 111 is not protruded in the receiving groove 113. Obviously, in other embodiments, the number of the elastic members 13 may be three, four, or the like.

Specifically, the two elastic members 13 are coil springs. The first locking member 10 further includes two limiting posts 14 on both sides of the horizontal bar 122 and extending between the first vertical edge 1121 and the vertical bar 121 respectively. The vertical bar 121 has corresponding two receiving holes (not shown) corresponding to the positions of the two limiting posts 14. One end of each of the limiting posts 14 is fixed to the first vertical side 1121 , and the other side is received in a corresponding receiving hole of the vertical strip 121 . The locking tongue portion 12 is movable along the limiting post 14 through the receiving hole. The two elastic members 13 are respectively sleeved on the corresponding one of the limiting posts 14, so that when the electromagnet 22 is energized to generate a magnetic force, as shown in FIG. 4, when the elastic member 13 is compressed, the locking tongue portion 12 is received. The hole gradually accommodates the limiting post 14 and moves in the direction of the opening 111, so that the horizontal bar 122 of the locking tongue portion 12 gradually protrudes from the opening 111 and protrudes into the receiving cavity 21. When the electromagnet 22 is de-energized, the magnetic force of the electromagnet 22 disappears, and the two elastic members 13 generate an elastic restoring force to push the vertical bar 121 of the bolt portion 12 to move away from the opening 111 along the limiting post 14. Thereby, the horizontal bar 122 retracts into the opening 111 without extending.

Specifically, the input device 30 can be an NFC (Near Field Communication) device or a radio frequency card reader for reading corresponding input information when sensing a user's NFC or RF card key.
