[0036] The embodiments of the present utility model will be further described below with reference to the accompanying drawings.

[0037] According to some embodiments of the present utility model, with reference to Figures 1 to 4, the electronic lock includes a lock body 100, a lock rod 200, a spring member 210, and a drive motor 230. A lock hole 101 communicating with the inner cavity of the lock body 100 is provided on the right side wall of the lock body 100. The lock rod 200 is disposed within the lock body 100 and is slidably connected to the lock body 100 in the left-right direction. A locking portion 201 is provided at the right end of the lock rod 200. When the lock rod 200 moves to the right, it can drive the locking portion 201 to extend out of the lock body 100 through the lock hole 101. When the lock rod 200 moves to the left, it can drive the locking portion 201 to retract into the lock body 100 through the lock hole 101. The spring member 210 is disposed within the lock body 100. The left end of the spring member 210 is connected to the lock body 100, and the right end of the spring member 210 is connected to the lock rod 200. The spring member 210 is always in a compressed state. The drive motor 230 is disposed within the lock body 100. A turntable 240 is fixedly connected to the drive end of the drive motor 230. The turntable 240 is provided with a push rod 241. The push rod 241 has at least a first position and a second position, wherein: when the turntable 240 rotates to move the push rod 241 from the first position to the second position, the push rod 241 abuts against the lock rod 200 and pushes the lock rod 200, and the locking portion 201 retracts into the lock body 100. When the turntable 240 rotates to move the push rod 241 from the second position to the first position, the push rod 241 separates from the lock rod 200, and the spring member 210 pushes the lock rod 200 to move, and the locking portion 201 extends out of the lock body 100 through the lock hole 101.

[0038] Figure 2 It is a schematic diagram of the push rod 241 in the first position. Figure 3 It is a schematic diagram of the push rod 241 in the second position.

[0039] Referring to Figure 2 and Figure 3 , when locking is required, the drive motor 230 drives the turntable 240 to rotate, so that the push rod 241 moves from the second position to the first position. The push rod 241 separates from the lock rod 200, and the spring member 210 pushes the lock rod 200 to move to the right, so that the locking portion 201 extends out of the lock body 100 through the lock hole 101. The groove wall of the lock body 100 restricts the lock rod 200 from continuing to move to the right to prevent the lock rod 200 from detaching from the lock body 100. At this time, the locking portion 201 is inserted into the lock groove of the door frame, thereby realizing the locking function. The spring member 210 continuously applies a rightward force to the lock rod 200 to prevent the locking portion 201 from detaching from the lock groove.

[0040] Referring to Figure 2 and Figure 3 , when unlocking is required, the drive motor 230 drives the turntable 240 to rotate, so that the push rod 241 moves from the first position to the second position. The push rod 241 abuts against the lock rod 200 and pushes the lock rod 200 to move to the left. The push rod 241 overcomes the force of the spring member 210 and further compresses the spring member 210, and the locking portion 201 retracts into the lock body 100 through the lock hole 101.

[0041] The structure of the electronic lock is simple, without the need for high-precision assembly. The assembly is simple and the reliability is strong.

[0042] According to some embodiments of the present invention, referring to Figures 2 to 4 , the lock rod 200 can slide in the left-right direction. A first groove 202 is provided at the left end of the lock rod 200. The right end of the spring member 210 is inserted into the first groove 202, so as to facilitate the positioning and assembly of the spring member 210 and prevent the spring member 210 from running off during operation.

[0043] According to some embodiments of the present invention, referring to Figure 2 and Figure 3 , a first clamping plate 110 and a second clamping plate 120 are provided in the lock body 100 at intervals in the left-right direction. The second clamping plate 120 is located on the right side of the first clamping plate 110. The driving motor 230 is arranged between the first clamping plate 110 and the second clamping plate 120. The first clamping plate 110 and the second clamping plate 120 are elastic. When the driving motor 230 is installed in the lock body 100, the first clamping plate 110 and the second clamping plate 120 jointly clamp the driving motor 230, facilitating the installation of the driving motor 230.

[0044] According to some embodiments of the present invention, referring to Figure 2 and Figure 3 , a second groove 121 is provided on the right side of the second clamping plate 120. The left end of the spring member 210 is inserted into the second groove 121, so as to facilitate the positioning and installation of the spring member 210 and prevent the spring member 210 from running off.

[0045] According to some embodiments of the present invention, referring to Figures 2 to 4 , a pushing portion 220 is provided at the upper end of the lock rod 200. The pushing portion 220 is provided with a third groove 221 extending in the left-right direction. The upper end of the push rod 241 is inserted into the third groove 221. When the push rod 241 moves from the first position to the second position, the push rod 241 abuts against the groove wall of the third groove 221 and pushes the pushing portion 220 to move leftward, thereby driving the lock rod 200 and the locking portion 201 to move leftward. When the push rod 241 moves from the second position to the first position, the push rod 241 no longer abuts against the groove wall of the third groove 221.

[0046] According to some embodiments of the present invention, referring to Figure 1 and Figure 5 , the electronic lock further includes a lock cover 130. The lock cover 130 is arranged in the lock body 100 and is detachably connected to the lock body 100. The lock cover 130 divides the inner cavity of the lock body 100 into a first area 131 and a second area 132. The second area 132 is located in front of the first area 131. The lock rod 200, the spring member 210 and the driving motor 230 are all located in the first area 131.

[0047] According to some embodiments of the present invention, referring toFigure 1 , the lock cover 130 is provided with a first notch 141, and the first notch 141 communicates the first area 131 and the second area 132, so as to facilitate the wire to extend from the first area 131 to the second area 132.

[0048] According to some embodiments of the present invention, with reference to Figure 1 and Figure 2 , a second notch 142 is provided on the side wall of the lock body 100, and the second notch 142 communicates with the second area 132. It can be understood that the front side of the lock body 100 is installed and attached to the door, and the wire extends from the first area 131 through the first notch 141 to the second area 132 and then extends out of the housing through the second area 132.

[0049] According to some embodiments of the present invention, the electronic lock further includes a control board, the control board is arranged in the second area 132, the control board is electrically connected to the driving motor 230, and the lock cover 130 can separate the driving motor 230 and the control board from each other to avoid interference.
