[0086] Specifically, the length of the first rotating shaft 101 is L1, and the length of the third connecting member 23 is L2. In the prior art, L2 / L1 < 0.4. In order to improve the connection strength between the upper cover 2 and the first rotating shaft 101, in this embodiment, L2 / L1 ≥ 0.9.

[0087] Specifically, a strengthening structure 104 is provided on the first rotating shaft 101.

[0088] This setting improves the structural strength of the first rotating shaft 101, makes the first rotating shaft 101 not easily damaged, and further improves the connection strength between the upper cover 2 and the first rotating shaft 101.

[0089] Specifically, the strengthening structure 104 is not specifically limited.

[0090] Specifically, as Figure 4 shown, the strengthening structure 104 is provided as a strengthening convex block, and the strengthening convex block is arranged around the bottom of the first rotating shaft 101.

[0091] Specifically, as Figure 3 shown, a limiting convex block 3 is provided on the lower cover 1, and the limiting convex block 3 abuts against or separates from the stop block 62.

[0092] This setting improves the stability and safety of the motor lock and has a good anti-vibration effect.

[0093] Specifically, the first micro switch 91 is arranged below the stop block 62, and the limiting convex block 3 is arranged above the stop block 62.

[0094] This setting further improves the stability of the motor lock and has a good anti-vibration effect.

[0097] This setting further improves the stability of the motor lock and has a good shockproof effect.

[0098] The storage cabinet includes a cabinet door body 10, and a lock hook 11 is arranged on the cabinet door body 10.

[0099] More specifically, as Figure 2 shown, a first installation groove 41 and a second installation groove are arranged on the motor box 55. The motor assembly is installed in the second installation groove, the motor control board 51 is installed in the first installation groove 41, and a sealing structure 42 is arranged in the first installation groove 41. The sealing structure 42 is used to prevent water from entering and damaging the motor control board 51.

[0101] In the closed state, as Figure 2 shown, when unlocking, the motor control board 51 of the motor module 50 receives an unlocking instruction, and the motor control board 51 can control the motor assembly to be powered on; the reduction motor 52 drives the screw 53 to rotate, driving the nut structure member 54 to move downward. The nut structure member 54 pulls the connecting rod 63 to move downward. The connecting rod 63 moving downward drives the stop torsion spring 61 and the stop block 62 to rotate clockwise. At the same time, the stop block 62 abuts against the first micro switch 91, triggering the first micro switch 91. The first micro switch 91 transmits an unlocking signal, and the stop assembly 60 unlocks the hook assembly 70. The hook block 72 and the stop block 62 slide relative to each other. The compression spring 71 generates a thrust on the hook block 72, causing the hook block 72 to rotate clockwise. The hook block 72 separates from the second micro switch 92, triggering the second micro switch 92. The second micro switch 92 transmits an unlocking signal, causing the lock hook 11 to disengage from the hook block 72 and move leftward, and the cabinet door body 10 opens. At the same time, the push spring 82 of the push rod assembly 80 pushes the push rod body 81 to move leftward under the action of the rebounding force, pushing the cabinet door body 10 to open the door together. When the motor control board 51 receives the unlocking signal transmitted by the first micro switch 91 or the second micro switch 92, the motor control board 51 controls the reduction motor 52 to reverse and push the nut structure member 54 to move upward to reset.

[0102] In the open state, as Figure 1As shown in the figure, when locking, the motor control board 51 of the motor module 50 receives a locking instruction, and the motor control board 51 can control the motor assembly to lose power; close the cabinet door body 10, push the lock hook 11 to move to the right, the lock hook 11 is hooked to the hook block 72, under the thrust of the lock hook 11, the hook block 72 rotates counterclockwise, and the compression spring 71 is compressed by the hook block 72 and the lock hook 11, the hook block 72 abuts against the second microswitch 92, triggering the second microswitch 92, the second microswitch 92 transmits a locking signal, at the same time, the cabinet door body 10 pushes the push rod body 81 to move to the right, and the push spring 82 is compressed; when the locking position is reached, the stop block 62 and the connecting rod 63 rotate counterclockwise under the action of the stop torsion spring 61, the stop block 62 abuts against the hook block 72 to realize closing the door; the stop block 62 is separated from the first microswitch 91, triggering the first microswitch 91, and the first microswitch 91 transmits a locking signal.
