[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0037] This embodiment provides an electronic lock with an anti-drop cover, such as... Figures 1 to 7 As shown, the device includes a front lock body 1 installed on the outside of the door panel and a rear lock body 2 installed on the inside of the door panel. The front lock body 1 includes a front base plate 10 and a front cover plate 11. An embedded groove 110 is provided on the front cover plate 11. A control component 111 for receiving control commands is provided in the embedded groove 110. The control component 111 includes a circuit board 1111 and an unlocking panel 1112. The unlocking panel 1112 is electrically connected to the circuit board 1111. The unlocking panel 1112 provides two unlocking methods: a password button and a palm vein recognition unit. By setting two unlocking methods, more choices can be provided to users to meet the needs of different occasions and personal preferences.

[0038] The rear lock body 2 includes a rear base plate 20 and a rear cover plate 21. A power assembly 22 is provided between the rear base plate 20 and the rear cover plate 21, and a power supply assembly 23 is also provided on the rear cover plate 21. The power supply assembly 23 is used to provide power to the control assembly 111 and the power assembly 22. The power supply assembly 23 includes a battery compartment 231 and a battery installed in the battery compartment 231.

[0039] The power assembly 22 comprises a mounting shell 221, a gear box 222 and a driven gear 223 are arranged in the mounting shell 221, a driving gear 2221 is arranged on the gear box 222 and engaged with the driven gear 223, the power assembly 22 further comprises a connecting shaft 224, the connecting shaft 224 penetrates the connecting shaft 224 along the center of the driven gear 223.

[0040] Further, the rotating shaft 4 and the lock tongue 5 are arranged between the front lock body 1 and the rear lock body 2, one end of the rotating shaft 4 is connected with the connecting shaft 224, a universal joint 40 is further arranged on the rotating shaft 4, and the rotating shaft 4 is connected with the lock tongue 5 through the universal joint 40. In use, when the user inputs the preset password or the palm vein recognition is successful, the control assembly 111 sends a signal to the power assembly 22 to start the unlocking action. At this time, the gear box 222 drives the driving gear 2221 to start rotating, the driving gear 2221 drives the driven gear 223 engaged with it to rotate, the connecting shaft 224 on the driven gear 223 rotates, and in turn drives the rotating shaft 4 to rotate. Since the rotating shaft 4 is connected with the lock tongue 5 through the universal joint 40, when the rotating shaft 4 rotates, the universal joint 40 converts the rotary motion into linear motion of the lock tongue 5, thereby pushing the lock tongue 5 to move, realizing the unlocking action.

[0041] Further, the rotating shaft 4 and the lock tongue 5 are arranged between the front lock body 1 and the rear lock body 2, one end of the rotating shaft 4 is connected with the connecting shaft 224, a universal joint 40 is further arranged on the rotating shaft 4, and the rotating shaft 4 is connected with the lock tongue 5 through the universal joint 40. In use, when the user inputs the preset password or the palm vein recognition is successful, the control assembly 111 sends a signal to the power assembly 22 to start the unlocking action. At this time, the gear box 222 drives the driving gear 2221 to start rotating, the driving gear 2221 drives the driven gear 223 engaged with it to rotate, the connecting shaft 224 on the driven gear 223 rotates, and in turn drives the rotating shaft 4 to rotate. Since the rotating shaft 4 is connected with the lock tongue 5 through the universal joint 40, when the rotating shaft 4 rotates, the universal joint 40 converts the rotary motion into linear motion of the lock tongue 5, thereby pushing the lock tongue 5 to move, realizing the unlocking action.

[0042] Further, the power assembly 22 further comprises a rotating handle 225, the rotating handle 225 is connected with the connecting shaft 224 and the other end of the rotating shaft 4. By arranging the rotating handle 225, when the user is located on the inside of the door, the rotating handle 225 is rotated to drive the connecting shaft 224 to rotate, and in turn drives the rotating shaft 4 to rotate, and finally drives the lock tongue 5 to move through the universal joint 40, completing the unlocking or locking action.

[0043] Further, the front cover plate 11 is further provided with a charging port 115. In an emergency, such as when the battery is out of power or the key is not in hand, the charging port 115 is used to externally connect an external power supply to provide power for the control assembly 111 and the power assembly 22, to ensure that the lock can continue to work normally.

[0044] Further, the lock cylinder 3 penetrates the front lock body 1 and is connected with the other end of the rotating shaft 4. By arranging the lock cylinder 3, in the case of battery power failure or electronic system failure, the user can use the traditional key to mechanically unlock, improving the reliability of the lock.

[0045] The cover 112 is used to cover the lock cylinder 3, avoiding the lock cylinder 3 from being exposed to the outside when not in use, so that the dust in the outside world enters the lock cylinder 3 and causes blockage. The magnetic attraction members 1122 are symmetrically arranged on the inner side of the cover 112, and the metal sheets corresponding to the magnetic attraction members 1122 are embedded on the front cover plate 11. By symmetrically arranging the magnetic attraction members 1122, it is ensured that the two magnetic attraction members 1122 can uniformly exert an attractive force, avoiding the problem that the cover 112 is inclined or cannot be completely closed due to uneven force on one side.

[0046] The connecting hooks 1121 are arranged on the inner side of the cover 112, and the rotating clamping grooves 114 corresponding to the connecting hooks 1121 are arranged on the front cover plate 11. The connecting hooks 1121 arranged on the inner side of the cover 112 and the rotating clamping grooves 114 arranged on the front cover plate 11 are both provided with two, the two connecting hooks 1121 are arranged in opposite directions, and the two rotating clamping grooves 114 are arranged in opposite directions. The connecting hooks 1121 in the same direction are clamped in the rotating clamping grooves 114 in the same direction.

[0047] Preferably, the opening of the connecting hook 1121 on the left side of the inner side of the cover 112 faces upward, and the opening of the connecting hook 1121 on the right side faces downward. Correspondingly, the opening of the rotating clamping groove 114 on the left side of the front cover plate 11 faces upward, and the opening of the rotating clamping groove 114 on the right side faces downward. When it is needed to buckle the cover 112, first, the connecting hook 1121 on the left side of the cover 112 is aligned with the rotating clamping groove 114 on the left side of the front cover plate 11, and at the same time, the connecting hook 1121 on the right side of the cover 112 is aligned with the rotating clamping groove 114 on the right side of the front cover plate 11. Then, the cover 112 is gradually moved close to the front cover plate 11. At this time, the magnetic attraction members 1122 on the inner side of the cover 112 will automatically attract the metal blocks on the front cover plate 11. Finally, with the further closing of the cover 112, the connecting hooks 1121 on both sides will be accurately clamped into the corresponding rotating clamping grooves 114. When it is needed to open the cover 112, if the cover 112 is directly pried away from the front cover plate 11, the connecting hooks 1121 on the inner side of the cover 112 will still be clamped with the rotating clamping grooves 114. At this time, the cover 112 needs to be turned counterclockwise by external force, so that the connecting hooks 1121 on the inner side of the cover 112 and the rotating clamping groove 114 on the left side of the front cover plate 11 are separated from each other, and then the cover 112 is removed. Because the cover plate and the front cover plate 11 are connected more stably by the cooperation of the magnetic attraction and the connecting hooks 1121 and the rotating clamping grooves 114, the situation that the cover 112 is accidentally detached due to frequent opening and closing of the door is avoided.

[0048] Further, the recess 113 extending inwardly is arranged on the inner side of the cover 112, which is used to place a spare key.

[0049] Further, the anti-falling rope 7 is arranged between the cover 112 and the front cover plate 11, one end of the anti-falling rope 7 is fixedly connected with the cover 112, and the other end of the anti-falling rope 7 is fixedly connected with the front cover plate 11.

[0050] The one end of the anti-falling rope 7 connected with the cover is fixed by adhesion, and the other end of the anti-falling rope 7 connected with the front cover plate 11 is fixed by the bolt 8, specifically, the anti-falling rope 7 is wound on the bolt 8, the front cover plate 11 is provided with a hole through which the bolt 8 passes, and the bolt 8 passes through the hole to fix the anti-falling rope 7.

[0051] In the description of the utility model, obviously, the described embodiment is only a part of the embodiment of the utility model, rather than all the embodiments. The components of the utility model embodiments described and shown in the drawings can be arranged and designed in various different configurations.

[0052] Therefore, the detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the claimed utility model, but only represents selected embodiments of the utility model.
