Description

Technical Field

[0001] This utility model relates to the field of door lock technology, and more specifically, to an electronic lock body structure. Background Technology

[0002] In the field of smart homes, electronic locks occupy a key position. They not only possess reliable security and intelligent management functions, but also provide a convenient user experience, thus gradually replacing traditional locks and becoming an essential item for ensuring security in modern life.

[0003] Current electronic locks use a motor to drive the bolt, achieving the purpose of locking and unlocking. However, when the motor drives the bolt, it immediately applies a load to the motor upon startup, resulting in a significant increase in instantaneous current. Over time, this can damage the motor. Utility Model Content

[0004] The present invention provides an electronic lock body structure, which aims to solve the problem that: when the existing electronic lock motor drives the lock tongue, the load is immediately applied to the motor, the instantaneous current of the motor increases, and the motor is easily damaged after long-term use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an electronic lock body structure, including a shell, a movable frame slidably disposed inside the shell, a fixed shaft installed inside the shell, a gear one located below the movable frame and a paddle mounted on the fixed shaft, a pin one provided on one side of the gear one, an arc-shaped groove opened on one side of the paddle, the pin one moving inside the arc-shaped groove, and the paddle driving the movable frame to move when it rotates; a lock tongue is installed at one end of the movable frame, a motor is disposed inside the shell, a gear two is installed at the output end of the motor, and the gear two meshes with the gear one.

[0006] Preferably, the movable frame has an inclined groove, and a lever is installed at one end of the lever, which moves inside the inclined groove.

[0007] Preferably, a side groove is provided at the edge of the gear, and a pin is provided on one side of the gear, which moves inside the side groove.

[0008] Preferably, the movable frame has a slot at the end away from the locking tongue, and the fixed shaft is located inside the slot.

[0009] Preferably, the housing includes a housing and an end cap, the end cap covering the housing, and the housing and the end cap being secured by screws.

[0010] The beneficial effects of this utility model are as follows:

[0011] This invention, by setting a pin and an arc-shaped groove, allows the motor to first drive the pin to slide inside the arc-shaped groove during unlocking and locking, without moving the movable frame and the lock tongue. Only when the pin moves to the other end of the arc-shaped groove does it begin to move the movable frame and the lock tongue. In other words, the position of the arc-shaped groove can act as a buffer position, preventing the current from increasing instantaneously when the motor is working, thus protecting the motor and increasing its service life.

[0017] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0018] Refer to the instruction manual appendix Figures 1-4 An electronic lock body structure includes a housing 1, which includes a shell 11 and an end cap 12. The end cap 12 covers the shell 11, and the shell 11 and the end cap 12 are fixed by screws.

[0019] The housing 1 has a sliding movable frame 2 inside, with a locking tongue 7 installed at one end. A fixed shaft 3 is also installed inside the housing 1, with a gear 4 and a lever 5 mounted on the fixed shaft 3, located below the movable frame 2. The lever 5 is positioned below the gear 4. A pin 41 is located on one side of the gear 4, and an arc-shaped groove 51 is formed on one side of the lever 5. The pin 41 moves within the arc-shaped groove 51, meaning that when the gear 4 rotates, it drives the pin 41 to slide within the arc-shaped groove 51. The movable frame 2 has a slanted groove 21, and a lever 52 is installed at one end of the lever 5. The lever 52 moves within the slanted groove 21, and when the lever 5 rotates, it drives the movable frame 2 to move.

[0020] The housing 1 houses a motor 6, and a gear 61 is mounted on the output end of the motor 6. Gear 61 meshes with gear 4. Thus, when the motor 6 drives gear 61 to rotate, gear 61 can drive gear 4 to rotate.

[0021] Working principle:

[0022] Initial state as Figures 1-4 As shown, the state is unlocked, with lever 52 located at one end of inclined groove 21 and pin 41 located at one end of arc groove 51.

[0023] When locking the door, motor 6 drives gear 2 61 to rotate, which in turn drives gear 4 and pin 41 to rotate. When pin 41 moves from one end of the arc-shaped groove 51 to the other, it begins to push the lever 5 to rotate. The lever 5 then drives the lever 52 to slide inside the inclined groove 21. The lever 52 pushes the movable frame 2 by pushing the side wall of the inclined groove 21. The movable frame 2 then moves the latch 7 towards the outside of the outer shell 1, thus achieving the purpose of locking the door. Similarly, when unlocking, motor 6 drives gear 2 61 to rotate in the opposite direction. Pin 41 first moves from one end of the arc-shaped groove 51 to the other before it begins to drive the lever 5 to rotate. The lever 5 then pulls the movable frame 2 through the lever 52, thereby moving the latch 7 towards the inside of the outer shell 1.

[0024] In the above technical solution, by setting the pin 41 and the arc groove 51, when unlocking and locking, the motor 6 first drives the pin 41 to slide inside the arc groove 51, without driving the movable frame 2 and the lock tongue 7 to move. Only when the pin 41 moves to the other end of the arc groove 51 does it start to drive the movable frame 2 and the lock tongue 7 to move. That is, the position of the arc groove 51 can act as a buffer position. When the motor 6 is working, the current will not increase instantaneously, which protects the motor 6 and increases the service life of the motor 6.

[0025] In this embodiment, as Figure 4 As shown, a side groove 53 is provided at the edge of the pusher 5, and a pin 42 is provided on one side of the gear 4. The pin 42 moves inside the side groove 53.

[0026] It should be noted that pin 42 rotates synchronously with gear 4. Pin 42 only begins to drive the paddle 5 to rotate when it moves from one end of the side groove 53 to the other end. In other words, pin 42 has the same function as pin 41. The setting of pin 42 can also improve the stability of driving paddle 5.

[0027] In this embodiment, as Figure 3 As shown, the movable frame 2 has a slot 22 at the end away from the locking tongue 7, and the fixed shaft 3 is located inside the slot 22.

[0028] It should be noted that the two sides of the movable frame 2 are in contact with the two walls inside the outer shell 1, so that the movable frame 2 can only slide inside the outer shell 1. The stability of the movable frame 2 can be further improved by setting the fixed shaft 3. When the movable frame 2 moves, the movable frame 2 slides inside the slot 22 relative to the movable frame 2.

[0029] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
