Description

Technical Field

[0001] This utility model relates to the field of electronic lock technology, and more specifically, to a novel anti-theft electronic lock. Background Technology

[0002] In existing technologies, window locks are generally mechanical locks, lacking electronic locks, making it impossible to link with smart home systems or remotely monitor unlocking. Therefore, this application designs a novel electronic window lock. Utility Model Content

[0003] To address at least one of the aforementioned problems, this utility model first provides a novel anti-theft electronic lock, comprising a rotary knob, a transmission component, a bolt, an electric push rod, a micro switch, a torsion spring, and a battery pack. The rotary knob is connected to and drives the transmission component to rotate. The transmission component includes a first pushing part and a second pushing part. The first pushing part is rotatably connected to the bolt and pushes the bolt to move and unlock. The second pushing part is adapted to rotate and abut against the micro switch to trigger the micro switch to transmit an unlocked signal to an external terminal device. The battery pack is connected to the micro switch to provide power. One end of the torsion spring is adapted to abut against the first pushing part to provide a restoring force. The electric push rod is used to push the transmission component to rotate and unlock.

[0004] Optionally, the first pushing part is non-circular, the electric push rod is located above the first pushing part, and a guide part is provided on the side wall of the first pushing part, the electric push rod being adapted to push the guide part to rotate.

[0005] Optionally, the latch is provided with a limiting opening, and the first pushing part is rotatably limited in the limiting opening. The limiting opening includes a first limiting wall and a second limiting wall. When in the locked state, the first pushing part abuts against the first limiting wall. When in the unlocked state, the first pushing part abuts against the second limiting wall.

[0006] Optionally, it also includes a connecting plate, on which the transmission component is rotatably mounted, and a limit bolt is installed on the connecting plate, the other end of the torsion spring being adapted to abut against the limit bolt.

[0007] Optionally, the latch is provided with a sliding groove and a limiting part, and the connecting plate is provided with a limiting block. The sliding groove and the limiting block are slidably connected, and the limiting part is adapted to abut against the limiting block to limit the movement distance when sliding to unlock.

[0008] Optionally, the locking tongue is provided with a connecting post, and the torsion spring is sleeved on the connecting post.

[0009] Optionally, the rotary knob includes a non-circular connecting shaft, the transmission component has a connecting port, the connecting shaft and the connecting port are inserted into each other, and the connecting shaft drives the transmission component to rotate through the connecting port.

[0010] Optionally, it also includes a housing, which has a battery cavity for accommodating the battery pack, a mounting port on the housing, through which the connecting shaft passes, and a contact portion on the rotary knob that extends out of the housing.

[0011] Compared to existing technologies, this novel anti-theft electronic lock uses a rotary knob and a first pusher unit for mechanical unlocking, while a second pusher unit triggers the signal. This design integrates mechanical transmission and status feedback into a single moving part, greatly simplifying the structure, reducing the number of parts and manufacturing costs, while improving system reliability. A torsion spring provides a stable mechanical reset force, ensuring the lock automatically returns to the locked position when not in use. The electric push rod connects wirelessly or wirelessly to a smart home system via a control device, allowing users to control locking and unlocking via mobile phones or other terminal systems. The electric push rod, acting as the electric unlocking actuator, coexists with the mechanical rotary knob unlocking method, enhancing the product's versatility. When triggered, a microswitch sends an "unlocked" signal to an external terminal (such as a smart home hub, property management system, or user's mobile app), enabling real-time, remote monitoring and recording of the unlocking status, thus increasing security.

[0017] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0018] The accompanying drawings of the embodiments of this utility model provide a coordinate system XYZ, where the positive direction of the X-axis represents the left and the negative direction of the X-axis represents the right, the positive direction of the Y-axis represents the front and the negative direction of the Y-axis represents the back, the positive direction of the Z-axis represents the top and the negative direction of the Z-axis represents the bottom.

[0019] This utility model embodiment provides a novel anti-theft electronic lock, combined with... Figures 1 to 3 As shown, the device includes a rotary knob 1, a transmission component 2, a latch 3, an electric push rod 4, a micro switch 5, a torsion spring 6, and a battery pack 7. The rotary knob 1 is connected to and drives the transmission component 2 to rotate. The transmission component 2 includes a first push part 21 and a second push part 22. The first push part 21 is rotatably connected to the latch 3 and pushes the latch 3 to move and unlock. The second push part 22 is adapted to rotate and abut against the micro switch 5 to trigger the micro switch 5 to transmit an unlocked signal to an external terminal device. The battery pack 7 is connected to the micro switch 5 to supply power. One end of the torsion spring 6 is adapted to abut against the first push part 21 to provide a restoring force. The electric push rod 4 is used to push the transmission component 2 to rotate and unlock.

[0020] like Figure 1 and Figure 2 As shown, in this embodiment, the rotary knob 1 and the first pusher 21 are responsible for the mechanical unlocking action, while the second pusher 22 is responsible for signal triggering. This design integrates the two functional modules of mechanical transmission and status feedback into a single moving part, greatly simplifying the structure, reducing the number of parts and manufacturing costs, while improving the reliability of the system. The torsion spring 6 provides a stable mechanical reset force, ensuring that the lock automatically returns to the locked position when not in operation. The electric push rod 4 is wirelessly or wirelessly connected to the smart home system through a control device, allowing users to control locking or unlocking via mobile phones or other terminal systems. The electric push rod 4, as the actuator for electric unlocking, coexists with the mechanical rotary knob 1 unlocking method, providing two unlocking methods and enhancing the product's applicability. After being triggered, the micro switch 5 sends an "unlocked" signal to an external terminal (such as a smart home hub, property management system, or user's mobile APP), realizing real-time, remote monitoring and recording of the unlocking status, increasing security.

[0021] Optionally, the first pushing part 21 is non-circular, the electric push rod 4 is disposed above the first pushing part 21, and a guide part 211 is provided on the side wall of the first pushing part 21. The electric push rod 4 is adapted to push the guide part 211 to rotate.

[0022] like Figure 2 and Figure 3 As shown, optionally, the locking tongue 3 is provided with a limiting opening 31, and the first pushing part 21 is rotatably limited in the limiting opening 31. The limiting opening 31 includes a first limiting wall 311 and a second limiting wall 312. When in the locked state, the first pushing part 21 abuts against the first limiting wall 311. When in the unlocked state, the first pushing part 21 abuts against the second limiting wall 312.

[0023] In this embodiment, the design of the limiting port 31 constitutes an efficient mechanism for converting rotational motion into linear motion. The first limiting wall 311 and the second limiting wall 312 together define the locking and unlocking limit positions of the bolt 3. This rigid limiting structure ensures that the end position of the bolt 3's stroke is accurate, eliminating the risk of overshoot or undershoot caused by inertia or tolerance, making the lock's working state clear and stable.

[0024] like Figure 2 As shown, optionally, it also includes a connecting plate 8, the transmission component 2 is rotatably mounted on the connecting plate 8, a limit bolt 81 is installed on the connecting plate 8, and the other end of the torsion spring 6 is adapted to abut against the limit bolt 81.

[0025] In this embodiment, the connecting plate 8 serves as the basic mounting platform for the entire transmission mechanism, ensuring the accuracy of the relative positions of each component and the rigidity of the overall structure. Using the limiting bolt 81 to fix one end of the torsion arm of the torsion spring 6 is ingenious, convenient, and reduces costs.

[0026] like Figure 2 As shown, optionally, the latch 3 is provided with a sliding groove 32 and a limiting part 33, and the connecting plate 8 is provided with a limiting block 82. The sliding groove 32 and the limiting block 82 are slidably connected, and the limiting part 33 is adapted to abut against the limiting block 82 to limit the movement distance when sliding to unlock.

[0027] In this embodiment, the cooperation between the slide groove 32 and the limiting block 82 provides precise guidance and reliable support for the linear movement of the locking tongue 3, preventing the locking tongue 3 from swaying or jamming during movement and ensuring smooth unlocking and resetting actions. The contact between the limiting part 33 and the limiting block 82 constitutes the second mechanical limiting guarantee for the linear movement stroke of the locking tongue 3. It works in conjunction with the limiting port 31 on the transmission component 2 to accurately lock the unlocking position of the locking tongue 3, share the impact force borne by the transmission component 2, and improve the mechanical strength and durability of the entire system.

[0028] like Figure 2 As shown, optionally, the locking tongue 3 is provided with a connecting post 34, and the torsion spring 6 is sleeved on the connecting post 34.

[0029] In this embodiment, the torsion spring 6 is directly sleeved on the connecting post 34 of the latch 3, which is a space-efficient and compact layout. This allows the point of application of the torsion spring 6's restoring force to be closer to the axis of motion of the latch 3, resulting in a more direct force transmission path, reducing unnecessary torque and friction, and improving energy transmission efficiency. Simultaneously, this installation method also ensures good positioning and protection for the torsion spring 6 itself, making its operation more stable and less prone to dislocation or deformation.

[0030] like Figure 3 As shown, optionally, the rotary knob 1 includes a non-circular connecting shaft 11, and the transmission component 2 is provided with a connecting port 23. The connecting shaft 11 and the connecting port 23 are inserted into each other, and the connecting shaft 11 drives the transmission component 2 to rotate through the connecting port 23.

[0031] In this embodiment, a non-circular (such as D-shaped, square, splined, etc.) connecting shaft 11 and connecting port 23 are used for plug-in connection, achieving efficient torque transmission without relative rotation between the rotary knob 1 and the transmission component 2. This connection method is simple in structure, easy to assemble, has no backlash in transmission, and responds promptly. Compared with simple methods such as round shafts with pins, the non-circular design can withstand greater torque, effectively preventing wear, slippage, or even failure at the connection point due to long-term use or violent operation, thus improving the reliability of manual unlocking.

[0032] like Figure 3 As shown, optionally, it also includes a housing 9, which has a battery cavity 91 for accommodating the battery pack 7, a mounting port 92 on the housing 9, through which the connecting shaft 11 passes, and a contact portion 12 on the rotary knob 1 that extends out of the housing 9.

[0033] In this embodiment, the outer casing 9 provides physical protection and structural support for the lock. The integrated battery compartment 91 design allows for built-in power, a clean appearance, easy battery replacement without additional wiring, and flexible installation. The mounting port 92 ensures that the connecting shaft 11 of the rotary knob 1 can extend precisely and stably and connect to the internal transmission component 2. The contact portion 12 on the rotary knob 1 (such as a knob handle) extends out of the outer casing 9 for easy manual operation. The overall outer casing 9 design encapsulates and protects the intricate internal mechanisms from dust and foreign objects, while also giving the product a unified and aesthetically pleasing external appearance.

[0034] Similarly, the components included in the "components," "mechanisms," and "devices" of this disclosure can also be flexibly combined. They can be modularly produced according to actual needs and assembled as an independent module; or they can be assembled separately to form a module in this device. The division of the above-mentioned components in this disclosure is only one embodiment for ease of reading and is not intended to limit the scope of protection of this disclosure. Any technical solution that includes the above-mentioned components and has the same function should be understood as an equivalent technical solution of this disclosure.

Therefore, they should not be construed as limitations on this disclosure.

[0036] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first," "second," etc., may explicitly or implicitly include at least one of that feature. In the description of this disclosure, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0037] In this disclosure, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly.

Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

When a component is considered to be "connected to another component," it can be directly connected to the other component or there may be an intervening component. Furthermore, when a component is considered to be "fixedly connected" to another component, the connection can be detachable or non-detachable, such as through socketing, snap-fitting, integral molding, welding, etc., which are achievable in conventional technologies and will not be elaborated upon here.

[0040] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] The above embodiments are merely illustrative of several implementation methods of this disclosure, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the inventive concept of this disclosure, and these modifications and improvements all fall within the protection scope of this disclosure.
