[0027] The technical solution of the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0028] Combination Figures 1 to 6 As shown, the electronic lock of this embodiment is arranged on the box body 1, and can be inserted and locked with the lock hole 3 arranged on the box cover 2. Specifically, the electronic lock includes a lock rod seat 4, a lock rod 5, a lock rod push rod 6, a reciprocating plate 7 and a lock piece 8. The lock rod seat 4 is reciprocatingly slidably arranged on the box body 1 through a lock rod seat spring 9, and the lock rod 5 is reciprocatingly slidably arranged on the lock rod seat 4 through a lock rod spring 10. The lock rod spring 10 can push the lock rod 5 relative to the lock rod seat 4 to extend into the lock hole 3, that is, push the lock rod 5 to Figure 2 Specifically, when the box cover 2 is turned to close, the box cover 2 can drive the lock plate 11 to abut against the inclined surface of the end of the lock rod 5, so as to push the lock rod 5 to overcome the lock rod spring 10 to retract and move the lock hole 3 to align with the lock rod 5, so that the lock rod 5 can move in the opposite direction under the action of the lock rod spring 10 and extend into the lock hole 3, completing the locking operation.

[0029] The locking rod push rod 6 is fixedly connected to the locking rod 5 along the radial direction of the locking rod 5. Figure 2 The vertical direction shown is fixedly connected to the lock rod 5 and can move synchronously with the lock rod 5 in the horizontal direction. The reciprocating plate 7 is connected to the motor 12, and the motor 12 can drive the reciprocating plate 7 to move back and forth, so as to push the lock rod push rod 6 to drive the lock rod 5 to overcome the lock rod spring 10 and move out of the lock hole 3, thereby completing the unlocking operation.

[0030] The lock piece 8 is provided with a lock opening 13 and is movably arranged on the box body 1. The code disk 14 can drive the lock piece 8 to move until the lock opening 13 is aligned with the lock rod seat 4, so that the lock rod seat spring 9 pushes the lock rod seat 4 to move away from the lock hole 3 into the lock opening 13, and then drives the lock rod 5 to move out of the lock hole 3, that is, the lock opening 13 and the lock rod seat 4 are aligned along the lock hole 3. Figure 2 When aligned in the horizontal direction as shown, the lock rod seat spring 9 can push the lock rod seat 4 to Figure 2 As shown, the lock moves in the left direction into the lock opening 13, thereby driving the lock rod 5 to move synchronously in the left direction, and then driving the lock rod 5 to move out of the lock hole 3, completing the unlocking operation.

[0031] In this embodiment, by arranging a lock plate driven by a code disk to cooperate with a lock rod seat, and a reciprocating plate driven by a motor to cooperate with the lock rod, the electronic lock can complete the unlocking operation by means of a code lock and an electronic lock respectively, so that when the electric system of the electronic lock is damaged or a power outage occurs, it can be opened by operating the code disk, thereby eliminating the need to use a key to unlock the lock and the need to store the key, thereby improving the ease of use of the electronic lock.

[0032] Combination Figures 1 to 6 As shown, in the electronic lock of this embodiment, a positioning plate 15 and a connecting pin 16 are also provided. The positioning plate 15 is slidably provided on the box body 1 in a vertical direction in a manner of being sleeved on the outside of the locking rod 5, and a positioning step 17 is provided on the locking rod 5. A positioning spring 18 is provided between the positioning plate 15 and the box body 1, and the positioning spring 18 can drive the positioning plate 15 to move to form abutment with the positioning step 17, thereby keeping the locking rod 5 in a state of extending into the lock hole 3. The connecting pin 16 is provided inside the box body 1 and connected to the positioning plate 15, so as to limit the positioning plate 15 to overcome the positioning spring 18 and break away from the abutment with the positioning step 17.

[0033] like Figure 2 As shown, the connecting nail 16 can position the positioning plate 15 at a position where it is sleeved outside the locking rod 5 and does not abut against the positioning step 17, so that the locking rod 5 can reciprocate horizontally relative to the locking rod seat 4. When the box body 1 is subjected to an external force to cause the connecting nail 16 to be disconnected from the box body 1 or disconnected from the positioning plate 15, the positioning spring 18 can drive the positioning plate 15 to move downward and abut against the positioning step 17 on the locking rod 5 in the horizontal direction, thereby limiting the horizontal movement of the locking rod 5 and locking the locking rod 5 in the lock hole 3 to complete the locking.

[0034] In this embodiment, by arranging the positioning plate and the connecting nail to cooperate, when the lock is removed by force from the outside, the connecting nail is separated from the connection with the box body or the positioning plate is separated from the connection with the connecting nail, the positioning plate can be moved to lock the locking rod in place, thereby preventing the box body from being unlocked when it is hit hard or the box cover is lifted with a lifting rod, thereby providing anti-theft performance.

[0035] Combination Figure 2 and Figure 4 As shown, in the electronic lock of this embodiment, the connecting nail 16 is fixedly connected to the top of the box body 1, and the free end of the connecting nail 16 extends downward and passes through the positioning groove 19 on the positioning plate 15. The positioning groove 19 is arranged along the direction from the top center of the box body 1 to the box cover 2. The connecting nail 16 is located at one end of the positioning groove 19 close to the top center of the box body 1, that is, the positioning groove 19 is arranged along the Figure 2The horizontal direction shown is arranged and the connecting nail 16 is located at the left end to limit the positioning plate 15 to overcome the positioning spring 18 and break away from the abutment with the positioning step 17.

[0036] In this embodiment, by setting the edge Figure 2 A horizontal positioning groove is provided, and a connecting nail is arranged at one end of the positioning groove close to the top center of the box body. In this way, when an external force hits the box body or pries the gap between the box body and the box cover, the top of the box body will be deformed and the connecting nail will bend along the direction of the positioning groove, thereby disconnecting the connecting nail from the positioning plate and moving the positioning plate to lock the locking rod.

[0037] Further, combined with Figure 2 and Figure 4 As shown, in the electronic lock of this embodiment, the free end of the connecting pin 16 is designed as a sphere, so that the spherical surface is used to support the positioning plate 15. In this way, the spherical surface with a smooth surface is used to support the positioning plate vertically upward, so that when the connecting pin is bent, the connecting pin and the positioning plate can be quickly and smoothly separated, thereby improving the response speed to violent knocking and prying, and improving the anti-theft effect.

[0038] Of course, in other embodiments, the connecting pin and the positioning plate may be fixedly connected, while the connecting pin and the box body may be detachably connected, such as an interference fit plug-in connection, so that when the box body is violently struck or pried, the interference fit between the connecting pin and the box body fails, causing the connection to become loose and detached.

[0039] Combination Figures 2 to 5 As shown, in the electronic lock of this embodiment, a control panel 20 is also provided. The control panel 20 is located below the positioning plate 15 and can reciprocate in a vertical plane to push the positioning plate 15 to overcome the positioning spring 18. Figure 2 The upper part as shown in the figure is moved away from the abutment with the positioning step 17.

[0040] In this embodiment, by setting up a control panel, the control panel can be used to drive the positioning plate in the locked state to move upward, so that the locking rod can move horizontally again to complete the release of the lock, so that the electronic lock can still be unlocked, will not affect the use of items stored in the box body, has higher anti-theft performance, and further improves the convenience of use.

[0041] Combination Figures 2 to 5As shown, in the electronic lock of this embodiment, the control disk 20 can reciprocate in a vertical plane, and the outer circumferential surface of the control disk 20 is provided with a large diameter surface 22 and a small diameter surface 21 which are smoothly transitionally connected. The control disk 20 can rotate until the large diameter surface 22 abuts against the locking positioning plate 15, so as to push the positioning plate 15 to overcome the positioning spring 18 and move upward, so that the positioning plate 15 is separated from the abutment with the positioning step 17, thereby completing the release of the lock.

[0042] Furthermore, in the electronic lock of this embodiment, a slide rail 23 and a connecting rod 24 are also provided, and the control disk 20 is arranged on the output shaft of the motor 12, and is driven by the motor 20 to reciprocate in a vertical plane. The slide rail 23 is arranged on the box body 1 along the reciprocating direction of the lock rod 5, and the reciprocating plate 7 is slidably connected to the slide rail 23. Relative to the rotation axis of the control disk 20, the connecting rod 24 is obliquely arranged between the control disk 20 and the reciprocating plate 7, one end of the connecting rod 24 is eccentrically hinged to the control disk 20, and the other end is eccentrically hinged to the reciprocating plate 7.

[0043] At this time, in the process of driving the control disk to rotate, on the one hand, the reciprocating plate can be driven to move back and forth in the horizontal direction through the connecting rod, thereby driving the locking rod to move through the locking rod push rod, and on the other hand, the positioning plate in the locked state can be pushed to move upward. In this way, only one motor can be set to complete the normal unlocking operation of the electronic lock and the unlocking of the locked state.

[0044] Among them, in this embodiment, by adjusting and setting the central angle of the large diameter surface, the horizontal distance between the lock rod push rod and the reciprocating plate in the locked state, and the relationship between the rotation angle of the control disk and the horizontal movement distance of the reciprocating plate, the positioning plate can be out of contact with the control disk in the normal state, and in the locked state, as the control disk rotates, the large diameter surface first contacts the positioning plate to push the positioning plate to move to release the locked state, and then the reciprocating plate and the lock rod push rod form contact to push the lock rod to move to unlock, so that a continuous action can be formed to complete the release and unlocking operations of the locked state.

[0045] Combination Figures 1 to 6 As shown, in the electronic lock of this embodiment, three mutually independent locking pieces 8 are provided, and at the same time, three corresponding locking rod seat pins 25 are provided on the locking rod seat 4. The three locking pieces 8 can be moved respectively until the three locking rod seat pins 25 are aligned with the three locking holes 13 at the same time, so that the three locking rod seat pins 25 enter the locking holes 13 on the three locking pieces 8 at the same time, so that the locking rod seat 4 carries the locking rod 5 to the locking position under the action of the locking rod seat spring 9. Figure 2 By setting a plurality of locking pieces, a plurality of corresponding password disks can be set to adjust the unlocking password and change the difficulty of password unlocking.

[0046] At the same time, in this embodiment, the code disk 14 and the lock plate 8 are coaxially fixedly connected and rotatably arranged outside the box body 1, thereby forming a rotary disk type code unlocking method.

[0047] In addition, combined Figure 1 and Figure 2 As shown, in the electronic lock of this embodiment, a lock rod seat block 26 is also provided. The lock rod seat block 26 is arranged at the end of the lock rod seat 4 and is located outside the box body 1 to drive the lock rod seat 4 to overcome the lock rod seat spring 9 to move. At this time, after unlocking the lock by the password disk, the lock rod seat block can be used to push the lock rod seat to overcome the lock rod seat spring and move in the reverse direction, so that the lock rod seat pin is pushed out of the lock port, and then the lock piece is rotated to complete the reset.

[0048] In addition, combined Figure 1 As shown, the box body 1 in which the electronic lock of this embodiment is set is also provided with a touch screen 27 for inputting a password and a fingerprint area 28 for inputting a fingerprint, so as to serve as a signal triggering unit for driving the motor 12 to operate. At the same time, a charging port 29 is also provided on the box body 1 for charging the power supply for the motor 12.

[0049] Combination Figures 1 to 6 As shown, the specific usage process of the jewelry box when the electronic lock of this embodiment is set is as follows:

[0050] Locking process: Place the items to be stored in the box body 1, close the box cover 2, insert the locking plate 11 into the locking plate opening 30 on the box body 1, so that the locking plate 11 pushes the locking rod 5 to overcome the locking rod spring 10 and retract, and when the locking hole 3 moves to align with the locking rod 5, the locking rod spring 10 drives the locking rod 5 to extend into the locking hole 3, completing the locking operation.

[0051] Electronic unlocking. Input the correct electronic unlocking signal through the touch screen 27 or fingerprint area 28 on the box body 1, and start the motor 12 to drive the control disk 20 to rotate. The control disk 20 pushes the reciprocating plate 7 along the slide rail 23 through the connecting rod 24. Figure 2 As shown in the figure, when the reciprocating plate 7 moves to abut against the locking rod push rod 6, the reciprocating plate 7 pushes the locking rod 5 through the locking rod push rod 6 to overcome the locking rod spring 10 and move to the left side. Figure 2 When the control disk 20 rotates 180 degrees, the reciprocating plate 7 moves to the left side. Figure 2 The left side of the box is moved to the farthest position, so that the lock rod 5 is moved out of the lock hole 3, and the electronic unlocking is completed. At this time, the box cover 2 can be opened and rotated, and the lock plate 11 exits the lock plate opening 30 as the box cover 2 rotates. After that, the motor 12 drives the control disk 20 to continue to rotate, and drives the reciprocating plate 7 to move to the left side of the box cover 2 through the connecting rod 24. Figure 2 The lock rod 5 moves to the right side as shown, and the lock rod 5 begins to move under the action of the lock rod spring 10. Figure 2 When the control disk 20 rotates 360 degrees, the reciprocating plate 7 moves back to the Figure 2 The locking rod 5 moves back to the position shown. Figure 2 The electronic unlocking is completed after the reset. In this process, the positioning plate 15 is in the position shown by the connecting pin 16. Figure 2 The lock rod seat 4 is also kept in the position shown in FIG. Figure 2 The position shown directly abuts against the locking plate 8.

[0052] The three code disks 14 are rotated to rotate the lock plate 8, so that the lock holes 13 on the three lock plates 8 are respectively aligned with the three lock rod seat pins 25 on the lock rod seat 4. Figure 2 The lock rod seat 4 is aligned in the horizontal direction as shown, so that the lock rod seat spring 9 is moved to the lock rod seat 4 under the action of the lock rod seat spring 9. Figure 2 The lock rod 5 moves in the left direction as shown in the figure, so that the lock rod seat pin 25 enters the lock hole 13, thereby driving the lock rod 5 to Figure 2 The lock plate 11 moves synchronously in the left direction as shown, and the lock rod 5 is removed from the lock hole 3, completing the unlocking of the code disk. At this time, the box cover 2 can be opened and rotated, and the lock plate 11 exits the lock plate opening 30 as the box cover 2 rotates. After that, the lock rod seat block 26 is pushed to Figure 2 The lock rod seat 4 is moved in the right direction as shown, so that the lock rod seat spring 9 can move, and the three lock rod seat pins 25 are all moved out of the lock hole 13. The combination disk 14 is rotated to make the lock hole 13 and the lock rod seat pins 25 staggered, so that the lock rod seat 4 is reset, the lock rod 5 is reset, and the reset after the combination disk is unlocked is completed. In this process, the positioning plate 15 is in the position under the action of the connecting pin 16. Figure 2 The lock rod seat 4 is also kept in the position shown in FIG. Figure 2 The position shown directly abuts against the locking plate 8.

[0053] When the box body 1 is hit by a strong external force, causing the top of the box body 1 to be concave and deformed, the connecting nail 16 forms a Figure 2 The bending in the right direction as shown in the figure causes the free end of the connecting nail 16 to bend toward the right direction of the positioning groove 19 and to be separated from the connection with the positioning plate 15. The positioning plate 15 begins to move toward the right side under the action of the positioning spring 18. Figure 2 As shown in the figure, it moves to the left side of the positioning step 17, forming a position along the positioning step 17. Figure 2 The horizontal abutment further locks the lock rod 5 in the position of extending into the lock hole 3, thereby completing the locking of the electronic lock.

[0054] After the electronic lock is locked, when it is necessary to unlock, the starter motor 12 drives the control disk 20 to rotate. Due to the downward movement of the positioning plate 15, the positioning plate 15 and the small diameter surface 21 of the control disk 20 are in contact. When the control disk 20 rotates 90 degrees, the large diameter surface 22 of the control disk 20 rotates to form abutment with the positioning plate 15, thereby pushing the positioning plate 15 to overcome the positioning spring 18. Figure 2 As shown in the figure, the positioning plate 15 releases the locking rod 5, and the control disk 20 continues to rotate with the motor 12. The positioning plate 15 remains in contact with the large diameter surface 22 of the control disk 20, and the reciprocating plate 7 abuts against the locking rod push rod 6 to push the locking rod 5 to Figure 2 As shown in the left direction, when the control disk 20 rotates 180 degrees, the reciprocating plate 7 pushes the locking rod 5 out of the lock hole 3 through the locking rod push rod 6, completing the opening after locking, and then the items in the box body 1 can be taken out and the electronic lock can be repaired.
