Description

Technical Field

[0001] This utility model relates to the field of lock technology, specifically to an abnormal detection lock body structure with a torque vibration sensor. Background Technology

[0002] Locks are a core component for protecting property, and their security primarily relies on the mechanical structure of the lock body. However, whether it is a traditional mechanical lock or a current smart lock, their lock bodies generally share a common defect: a lack of ability to sense their own status and external intrusion.

[0003] Specifically, existing lock bodies cannot effectively distinguish between normal operation and abnormal situations. For example, when subjected to forced entry, technical unlocking, or internal parts malfunction due to wear, the lock body can only passively withstand the damage. Users often only discover the problem after the lock has completely failed, missing the best opportunity for early warning and prevention. To address this, we propose an abnormal detection lock body structure with a torque vibration sensor. Utility Model Content

[0004] The purpose of this invention is to provide an abnormal detection lock body structure with a torque vibration sensor, which has the advantages of real-time sensing of torque and impact vibration during operation and timely and accurate warning, thus solving the problem that existing locks lack the ability to sense their own status and external damage.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an abnormal detection lock body structure with a torque vibration sensor, comprising: Front panel, lock body, rear panel, T-shaped bracket, and control box; A battery is installed on one side of the interior of the front panel; The lock body has a lock cylinder on its inner surface at the lower end. The rear plate has an alarm and a display screen on one side of the upper end. Both the front and rear plates have handles on their upper ends. A square rod is installed at one end of the handle, and a strain gauge is installed at the top of one end of the square rod. The T-shaped bracket is installed on one side inside the front panel, and a mounting base is fixed on one side of the T-shaped bracket. A vibration sensor is embedded on one side of the mounting base. The control box is installed on one side inside the rear panel, and a processor and a signal transceiver are installed on one side inside the control box.

[0006] Preferably, the lower end of the front panel is provided with a protective cover.

[0007] Preferably, one side of the vibration sensor is in contact with the surface of the lock body.

[0008] Preferably, a vibration damping pad is adhered to one side of the control box.

[0009] Preferably, porous foam layers are bonded to both the upper and lower ends of the front and rear panels.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. By installing strain gauges on the core transmission component square rod and directly contacting vibration sensors on the lock body, this utility model can monitor abnormal torque and vibration signals such as illegal lock picking and violent damage in real time and accurately. Once a threat is detected, the system can sound an alarm on-site and simultaneously send warning information remotely to the user's mobile terminal, realizing a qualitative change from passive protection to active early warning, and providing valuable response time for users and security systems.

[0011] 2. By analyzing long-term torque data, this utility model can identify mechanical failure trends caused by component wear, poor lubrication, etc., such as an abnormal increase in unlocking torque, and issue maintenance reminders to users, effectively avoiding the predicament of locks becoming unusable due to sudden failures, and realizing preventive maintenance.

[0012] 3. This utility model highly integrates the sensing, processing and alarm units. The vibration isolation pads added to the control box can effectively isolate the interference of external vibrations on the processing circuit. The porous foam layers inside the front and rear panels not only play a role in heat preservation and moisture retention, but also absorb high-frequency vibration noise, providing a stable working environment for the sensor and ensuring the accuracy of the detection results and the reliability of the system's long-term operation.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] The components of this application, including the front panel 1, protective shell 101, handle 102, square rod 103, battery 104, strain gauge 105, lock body 2, lock cylinder 201, rear panel 3, alarm 301, display screen 302, T-shaped bracket 4, mounting base 401, vibration sensor 402, control box 5, vibration isolation pad 501, processor 502, signal transceiver 503, and porous foam layer 6, are all general standard parts or parts known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0017] Example 1 Please see Figures 1-5 As shown, this utility model provides a technical solution: an abnormal detection lock body structure with a torque vibration sensor, comprising: Front panel 1, lock body 2, rear panel 3, T-shaped bracket 4, and control box 5; Among them, a storage battery 104 is installed on one side inside the front panel 1; Among them, the inner surface of the lower end of the lock body 2 is provided with a lock cylinder 201; Among them, an alarm 301 and a display screen 302 are provided on the upper end of one side of the rear plate 3, and a handle 102 is provided on the upper end of both the front plate 1 and the rear plate 3. A square rod 103 is installed on one end of the handle 102, and a strain gauge 105 is installed on the top of one end of the square rod 103. Among them, the T-shaped bracket 4 is installed on one side inside the front panel 1, and a mounting base 401 is fixed on one side of the T-shaped bracket 4. A vibration sensor 402 is embedded on one side of the mounting base 401. The control box 5 is installed on one side inside the rear panel 3, and the processor 502 and the signal transceiver 503 are installed on one side inside the control box 5.

[0018] One side of the vibration sensor 402 is in contact with the surface of the lock body 2.

[0019] This technical solution is as follows: First, the T-shaped bracket 4 is reliably fixed to the side wall inside the front panel 1. Then, the vibration sensor 402 is embedded and fixed in the mounting base 401 to ensure that the detection surface of the vibration sensor 402 is in close contact with the surface of the lock body 2 to best transmit the vibration signal. Next, the square rod 103 serves as the core carrier for torque detection, with one end inserted into the dial mechanism of the lock tongue. The strain gauge 105 serves as a torque sensor and is fixed at a specific position on the top of the square rod 103 by precision mounting. This is the area most sensitive to the transmission torque. The control box 5 is installed inside the rear panel 3 and is bonded to the rear panel 3 by vibration isolation pad 501 to attenuate irrelevant vibrations transmitted from the door panel, protect internal electronic components, and reduce signal noise. Finally, the front panel 1, lock body 2, and rear panel 3 are assembled into the predetermined position of the door. During operation, each sensor continuously monitors the system. Strain gauge 105 senses the torque experienced by the square rod 103 during the opening and closing process and transmits the weak resistance change signal to processor 502. Vibration sensor 402 monitors various impacts and vibrations experienced by the lock body 2 in real time and transmits the vibration signal synchronously to processor 502. Processor 502 performs real-time analysis, filtering, and feature extraction on the input torque and vibration signals. It has pre-stored data models of normal operation and various abnormal situations (such as forced prying, technical unlocking, and violent impact) obtained through numerous experiments. When the monitored signal characteristics match the abnormal model, it is determined to be a security threat or mechanical failure. Processor 502 immediately performs the following operations through signal transceiver 503: The alarm 301 is activated, emitting a strong on-site audible and visual warning. The alarm event (including type and time) is displayed on the screen 302, and detailed alarm information is pushed to the user's bound mobile terminal via a wireless network (such as Wi-Fi or cellular network). The entire structure is independently powered by the battery 104 inside the front panel 1, ensuring normal operation even when the mains power is interrupted.

[0020] Example 2 Based on Embodiment 1, this utility model is as follows: Figures 1-5 As shown, a protective cover 101 is provided at the lower end of the front panel 1.

[0021] This technical solution provides physical protection to the outside of the lock cylinder 201 by setting up the protective cover 101.

[0022] Example 3 Based on Embodiment 1, this utility model is as follows: Figures 1-5 As shown, a vibration isolation pad 501 is adhered to one side of the control box 5.

[0023] This technical solution: By setting the vibration isolation pad 501, it can be used to attenuate irrelevant vibrations transmitted from the door panel, protect internal electronic components, and reduce signal noise.

[0024] Example 4 Based on Embodiment 1, this utility model is as follows: Figures 1-5 As shown, porous foam layers 6 are bonded to both the upper and lower ends of the front panel 1 and the rear panel 3.

[0025] This technical solution: By setting up the porous foam layer 6, it can not only play a role in heat preservation and moisture retention, but its porous structure can also effectively absorb high-frequency mechanical noise, providing a purer signal source for the vibration sensor 402 and reducing false alarms.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
