[0030] The embodiments of this utility model will be further described below with reference to the accompanying drawings:

[0031] As shown in Figure 1 and Figures 2-5, an electric electronic lock includes a housing 1 and a main bolt 2, and further includes:

[0032] Power source 3 is located inside housing 1;

[0033] The main locking tongue push plate 4 is located inside the housing 1. The main locking tongue 2 is located on the main locking tongue push plate 4 and is driven by the main locking tongue push plate 4 to reciprocate.

[0034] Gear mechanism 5, wherein the power source 3 is connected to gear mechanism 5 and is used to drive gear mechanism 5 to move;

[0035] The transmission mechanism 6 is located inside the housing 1. The gear mechanism 5 is connected to the main locking tongue push plate 4 through the transmission mechanism 6 and is used to drive the main locking tongue push plate 4 to move.

[0036] A clutch mechanism 7 is located within the housing 1, positioned between the power source 3 and the gear mechanism 5. The clutch mechanism 7 has a first position where it engages, causing the power source 3 to drive the gear mechanism 5, and a second position where it disengages. The advantages of this invention are that the clutch mechanism allows for simple and quick disengagement and engagement, enabling rapid manual / automatic switching. The product has a simple structure, few parts, convenient transmission, reliable performance, low assembly difficulty, and occupies little space within the housing, facilitating the assembly of other components. Specifically, a circuit board is typically installed within the housing, connected to the power source and used to control its operation. When the user unlocks the door using commands such as light, electricity, magnetism, sound, password, facial recognition, and / or fingerprint recognition, the control circuit board uses the power source to retract the main lock tongue to unlock, facilitating door opening.

[0037] The clutch mechanism 7 includes:

[0038] The clutch rotating shaft 71 is connected to the gear mechanism 5 and is used to drive the gear mechanism 5 to move.

[0039] The clutch wheel 72 is connected to the power source 3 and is driven to rotate by the power source 3. The clutch wheel 72 is in circumferential rotational cooperation and axial sliding cooperation with the clutch rotation shaft 71.

[0040] A clutch lever 73, mounted on the housing 1, is connected to a clutch wheel 72 and drives the clutch wheel 72 to slide axially relative to the clutch rotation shaft 71, thus placing the clutch mechanism 7 in a disengaged second position. This structure reliably drives the clutch wheel via the clutch lever, achieving clutch engagement and disengagement. When powered, the gear mechanism reliably drives the transmission mechanism, thereby actuating the main latch and achieving interlocking or unlocking. When manually unlocking or unlocking with a key, the clutch lever rotates, disengaging the clutch mechanism. This prevents the gear mechanism from driving the power source in the opposite direction during manual or key unlocking, avoiding damage to components and extending product lifespan.

[0041] The clutch rotating shaft 71 includes an axial sliding part 711 and a bevel gear part 712 connected to the gear mechanism 5. The clutch dial 72 is sleeved on the axial sliding part 711 and rotates circumferentially with the clutch rotating shaft 71 while sliding axially.

[0044] The clutch lever 73 is provided with a clutch drive part 731 for easy driving of the transmission mechanism 6 and a clutch lever foot 732 for easy driving of the clutch wheel 72. The clutch drive part 731 and the clutch lever foot 732 are located at both ends of the clutch lever 73. Specifically, the clutch wheel 72 includes a clutch drive plate 721. There are two clutch drive plates 721, which form a clutch drive groove 722. The clutch lever foot 732 is U-shaped and inserted into the clutch drive groove 722. When the clutch lever 73 rotates, the clutch lever foot 732 drives the clutch wheel 72 to move axially along the clutch rotation shaft 71. The clutch lever foot is inserted into the clutch drive groove, and the clutch wheel can be reliably driven to move linearly during operation. The structure is simple. The end of the clutch lever foot is round, spherical, or arc-shaped, so that the force is evenly distributed, the transmission is convenient and reliable, and the damage to the parts is small.

In fact, a straight line hole is also provided at the axial sliding part where the clutch wheel mates with the clutch rotation shaft. This structure is simple, easy to connect and assemble, and has high product strength. Of course, in practice, different shapes of holes and slots, such as cross-shaped or floral-shaped, can also be used to achieve the mating.

[0046] The transmission mechanism 6 includes a transmission gear 61 and a main locking tongue lever 62. The gear mechanism 5 meshes with the transmission gear 61 and drives the main locking tongue lever 62 to rotate via the transmission gear 61. The main locking tongue lever 62 is connected to the main locking tongue push plate 4, which in turn drives the main locking tongue push plate 4 to reciprocate. This structure enables the transmission mechanism to reliably drive the main locking tongue, and it is simple in structure and convenient and reliable in operation.
