[0027] The embodiments of the present disclosure will be described in detail below with reference to the drawings.

[0028] The embodiments of the present disclosure will be described in detail below with reference to the drawings.

[0029] It should be apparent that the described embodiments are only some embodiments of the present disclosure, but not all the embodiments. The present disclosure can also be implemented or applied by other different specific embodiments, and each detail in the specification can be modified or changed based on different views and applications without departing from the spirit of the present disclosure. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present disclosure.

[0030] It should also be noted that the drawings provided in the following embodiments only schematically illustrate the basic concept of the present disclosure, and only the components related to the present disclosure are shown in the drawings, not the number, shape and size of the components when actually implemented. The shape, number and ratio of each component in actual implementation can be arbitrarily changed, and the layout pattern of the components can also be more complex.

[0031] In addition, in the following description, specific details are provided to facilitate a thorough understanding of the examples. However, one skilled in the relevant art will understand that the described aspects can be practiced without these specific details.

[0032] As shown in Figure 1 , a smart community Internet of Things access control device of the present application includes a fixed frame 1, a hinge assembly 2, a lock core assembly 3, an anti-damage baffle 4, an induction trigger piece 5, and an elastic reset piece 6. These components work together to achieve stability and security of the access control device.

[0033] The fixed frame 1 is a rigid metal frame used to securely fix the entire device to the door frame, ensuring that the entire device will not be displaced due to external physical actions. One end of the hinge assembly 2 is connected to the fixed frame 1, and the other end is connected to the door leaf, allowing the door leaf to open and close smoothly. The lock core assembly 3 is embedded inside the fixed frame 1 and, through internal mechanical mechanisms and electronic control systems, achieves the locking and unlocking functions of the door lock. The design of the lock core assembly 3 includes an internal motor and transmission device, which, by receiving signals from induction cards or remote control, drives the motor to perform the extension and retraction operation of the lock tongue 12.

[0034] The anti-damage baffle 4 is placed in front of the lock core assembly 3 and is made of high-strength material, capable of resisting external impact forces and protecting the lock core assembly 3 from damage. The anti-damage baffle 4 not only has good impact resistance, but also effectively disperses external forces, preventing them from directly acting on the lock core assembly 3. The induction trigger piece 5 is installed inside the anti-damage baffle 4 and, when the door is subjected to an external force impact exceeding the preset force, the induction trigger piece 5 will be activated and send a signal to the central control system, triggering appropriate safety measures such as alarm activation or recording of the impact event. The elastic reset piece 6 (see Figure 2 ) is located between the anti-damage baffle 4 and the lock core assembly 3 and can quickly return to the initial position after the anti-damage baffle 4 is impacted, ensuring that the access control device is always in normal working condition. The elastic reset piece 6 is usually composed of a spring made of high-elasticity material, which can provide sufficient elastic force to ensure that the anti-damage baffle 4 remains stable after multiple impacts.

[0035] Specifically, the fixed frame 1 can be connected with the door frame by welding or bolting to ensure its stability. The hinge assembly 2 can be connected with the fixed frame 1 and the door leaf through a rotating shaft, and bearings are used to reduce friction and improve the smoothness of the door leaf opening and closing. The lock core assembly 3 includes a microprocessor, a motor, a transmission device, and an electromagnetic lock, etc. After receiving the door opening signal, the microprocessor controls the rotation of the motor, and the transmission device drives the extension and retraction of the lock tongue 12. The manufacturing material of the anti-damage baffle 4 can be steel or other high-strength alloys, and it is manufactured by stamping process to ensure that it does not deform when subjected to a large impact force. The induction trigger piece 5 can use piezoelectric ceramic material, which generates an electric signal when subjected to external impact, and the signal is transmitted to the control system through the circuit board. The elastic reset member 6 can be a coil spring, and the appropriate spring stiffness is selected according to the design requirements to ensure that it can quickly reset under different impact forces.

[0036] The Internet of Things access control device solves the problem of damage to the access control device caused by violent opening through the cooperation of the above-mentioned parts. Specifically, the anti-damage baffle 4 can effectively absorb and disperse impact force, avoiding the direct action of external force on the lock core assembly 3; the induction trigger piece 5 can immediately send an alarm when subjected to an impact exceeding the preset force, notifying the management personnel to handle the abnormal situation in time; and the elastic reset member 6 ensures that the anti-damage baffle 4 can quickly return to its original position even after multiple impacts, maintaining the overall stability of the device. These designs not only improve the safety of the access control system, but also prolong its service life.

[0037] Still referring to Figure 1 In one embodiment, the fixed frame 1 of the Internet of Things access control device for smart community of the present application is made of high-strength metal material. High-strength metal material has excellent tensile strength and impact resistance, which can effectively prevent the access control device from deforming or damaging when subjected to external violent impact. The fixed frame 1 is designed to provide strong mechanical support to ensure the stability and safety of the entire access control device. The fixed frame 1 is stably fixed on the door frame by a plurality of fixing bolts 7, which are evenly distributed on different parts of the fixed frame 1, forming a multi-point fixed structure to enhance the overall rigidity and stability of the device.

[0038] Specifically, the fixed frame 1 is usually rectangular or rectangular, and the installation position is close to the inner side edge of the door frame. One side of the fixed frame 1 is in contact with the door frame and is smoothed to reduce the wear of the contact area and increase the fixing effect. The number and distribution of the fixing bolts 7 are adjusted according to the specific installation requirements. Usually, two bolts are installed at each corner, and one or two bolts are installed at intervals in the middle part to ensure that each stress point is effectively supported. The contact surface between the fixed frame 1 and the door frame can also be equipped with a gasket to further improve the reliability of the fixing. This design not only enhances the stability of the device, but also simplifies the installation and maintenance process. For example, by selecting the appropriate length of the fixing bolt 7, the device can adapt to door frames of different thicknesses, ensuring that the device can work stably in various environments.

[0039] Reference Figure 2 In one embodiment, the hinge assembly 2 of the smart community IoT access control device of the present application is composed of one or more sets of stainless steel shaft pins and hinge plates that cooperate with each other. Specifically, each set of hinge assembly 2 includes multiple stainless steel shaft pins and hinge plates that cooperate with them. Each stainless steel shaft pin is installed between two hinge plates to ensure stable connection of the hinge assembly 2 between the door leaf and the door frame. In order to reduce the noise generated by the door leaf during opening and closing, and effectively buffer the impact force received by the door leaf, a shock-absorbing rubber washer 8 is provided at both ends of each stainless steel shaft pin. The shock-absorbing rubber washer 8 is located between the shaft pin and the hinge plate, forming an effective buffer layer to protect the structural stability and durability of the hinge assembly 2 during long-term use.

[0040] For example, in actual technical implementation, the hinge plate is fixed at the predetermined position of the door leaf and the door frame by screws or rivets. The stainless steel shaft pin is inserted into the corresponding hole on the hinge plate to ensure that the shaft pin can rotate freely between the hinge plates. Then, the shock-absorbing rubber washer 8 is fitted at both ends of the stainless steel shaft pin and tightly fitted on the inner side of the hinge plate, thereby playing an effective shock-absorbing and buffering role when the door leaf is opened and closed. This design not only reduces noise, but also prolongs the service life of the hinge assembly 2.

[0041] In one embodiment, the cooperation design of the shock-absorbing rubber washer 8 and the stainless steel shaft pin of the smart community IoT access control device of the present application significantly improves the stability and reliability of the device. Specifically, the shock-absorbing rubber washer 8 is installed at the shaft between the door leaf and the frame, and is connected with the stainless steel shaft pin through interference fit. This connection ensures that the washer will not fall off or loosen during long-term repeated opening and closing of the door leaf. The interference fit design makes the shock-absorbing rubber washer 8 tightly fit the stainless steel shaft pin, forming a stable combination that effectively prevents the washer from falling out due to external vibration or impact.

[0042] For example, when technically implementing this feature, a shock-absorbing rubber washer 8 of appropriate thickness and material can be selected, and precise mold processing can be performed according to the diameter and shape of the shaft pin to ensure the appropriate interference. The stainless steel shaft pin needs to be finely processed and polished to ensure a smooth and flawless surface, so that it can achieve close contact with the rubber washer during assembly and achieve the expected stability effect.

[0043] In one embodiment, a reinforcing rib 9 is provided between the hinge leaves of the smart community IoT access control device of the present application, which is used to enhance the overall strength and toughness of the hinge. The reinforcing rib 9 is arranged to effectively resist external forces during multiple opening and closing of the door leaf, avoiding deformation or damage due to stress concentration. Specifically, the reinforcing rib 9 is fixed between the two hinge leaves and firmly combined with the hinge leaves through welding or other reliable connection methods. The material of the reinforcing rib 9 should be consistent with that of the hinge leaves to ensure the overall durability and reliability.

[0044] In one embodiment, the design shape of the reinforcing rib 9 can be optimized according to the actual stress condition of the hinge. For example, the reinforcing rib 9 can be in the shape of a long strip, arranged horizontally or vertically in the gap between the hinge leaves, or can adopt a grid structure to further improve the strength. Specifically, corresponding mounting grooves or holes can be processed on the inner side of the hinge leaves to facilitate precise positioning and fixation of the reinforcing rib 9. Such design not only improves the structural stability of the hinge, but also ensures its long-term reliability and safety.

[0045] In one embodiment, as shown in Figure 3 The lock core assembly 3 of the smart community IoT access control device of the present application is internally provided with a micro motor 10 and a transmission gear set 11. The micro motor 10 drives the extension and retraction of the lock tongue 12 through the transmission gear set 11, thereby realizing the locking and unlocking functions of the door lock. In addition, the lock core assembly 3 is also integrated with an induction trigger piece 5, which is used to detect whether the door is subjected to violent impact. When the induction trigger piece 5 detects that the door is subjected to violent impact, the micro motor 10 can quickly respond and lock the lock tongue 12 to prevent the door from being forcibly opened.

[0046] Specifically, the lock core assembly 3 includes a micro motor 10, a transmission gear set 11, and a lock tongue 12. The micro motor 10 and the transmission gear set 11 are installed inside the lock core assembly 3, and the mechanical connection ensures that the transmission gear set 11 can transmit the power of the micro motor 10 to the lock tongue 12. The movement path of the lock tongue 12 is precisely designed to ensure that it can reliably perform extension and retraction actions under the drive of the micro motor 10. The induction trigger piece 5 is installed at a suitable position of the door frame or door body to monitor the state of the door in real time. Once the induction trigger piece 5 detects an abnormal impact signal, it immediately sends an instruction to the micro motor 10 through the control system, causing the lock tongue 12 to lock quickly.

[0047] For example, in one specific implementation, the micro motor 10 drives the bolt 12 to extend and retract through a set of precisely meshed transmission gears 11. The bolt 12 is fixed at both ends in the lock cylinder assembly 3 and the door body structure, ensuring accurate positioning. The induction trigger 5 uses a high-sensitivity sensor installed on the edge of the door frame to ensure timely alarm and trigger the micro motor 10's rapid response when the door is subjected to violent impact.

[0048] In one embodiment, the transmission gear set 11 of the smart community IoT access control device of the present application is composed of high-precision stainless steel gears and racks. Through the optimization of gear modulus and tooth shape, the device realizes high efficiency and low noise in power transmission, and can effectively resist external violent impact, thereby ensuring the normal function of the lock. Each component in the gear set adopts high-precision machining process to ensure the tightness and stability of the gears and racks when meshing. The selection of high-precision stainless steel material not only provides sufficient strength and corrosion resistance, but also ensures the reliability of long-term operation.

[0049] In one embodiment, the transmission gear set 11 is installed in the internal mechanical transmission system of the access control device, located between the motor and the lock. The high-precision stainless steel gears and racks are connected through precise alignment and fixing method, ensuring effective power transmission. Specifically, the gears are sleeved on the rotating shaft through the center hole and fixed with keyway; the racks are fixed on the lock mechanism through the connecting pieces at both ends, ensuring that they will not shift under stress. Such structural design not only enhances the overall stability of the device, but also improves its impact resistance. For example, when encountering external impact, the gear set can absorb and disperse impact energy through its structural strength and optimized meshing parameters, avoiding the failure of the lock due to impact.

[0050] In one embodiment, the micro motor 10 of the smart community IoT access control device of the present application is provided with an overload protection device 13 between the transmission gear set. When the lock cylinder assembly 3 is subjected to external force impact exceeding the set range, the overload protection device 13 can cut off the power supply of the micro motor 10, avoiding the burning of the motor due to overload. The specific design of the overload protection device 13 makes the access control system have better reliability and safety when encountering abnormal situations.

[0051] The overload protection device 13 is installed on the transmission path between the micro motor 10 and the transmission gear set, which can monitor and respond to overload in real time. The device is usually composed of sensors, controllers, relays and other components. Among them, the sensor is used to detect the running state of the micro motor 10, including current and torque parameters; the controller judges whether the safety threshold is exceeded according to the sensor feedback information; if the threshold is exceeded, the controller will issue an instruction to make the relay act, thereby cutting off the power supply of the micro motor 10.

[0052] For example, in a specific implementation, the sensor can be a current transformer or a torque sensor installed near the output shaft of the micro motor 10. When an external force impact causes a sudden change in current or torque, the sensor immediately detects the change and triggers the relay to cut off the motor power through the controller, effectively preventing the motor from being damaged by overload.

[0053] In one embodiment, the anti-damage baffle 4 of the smart community IoT access control device of the present application adopts a multi-layer composite structure. The outer layer of the baffle is made of a layer of bulletproof fiber material, and the inner layer is a high-density plastic layer. The outer layer of bulletproof fiber has excellent impact resistance, which can quickly absorb and disperse energy when encountering external impact, preventing the impact force from being directly transmitted to the internal components. The inner layer of high-density plastic further enhances the stability of the structure, ensuring that the internal lock core assembly 3 is not damaged when subjected to external impact. The overall structure design is compact, and the installation position is located at the most vulnerable part of the access control device, such as the key parts above or below the door handle, forming effective protection for the key components.

[0054] Specifically, the outer layer and the inner layer of the anti-damage baffle 4 are tightly attached by adhesive or other suitable means to form a solid whole. Between the outer layer and the inner layer, a layer of elastic material can also be added to further improve the impact resistance. For example, this layer of elastic material can be foam or rubber, which can effectively deform and quickly absorb energy when subjected to impact, reducing the impact on the internal lock core assembly 3. The baffle is fixed on the housing of the access control device by screws or other fasteners to ensure its stability and prevent accidental loosening.

[0055] In one embodiment, as shown in Figure 4 The anti-damage baffle 4 of the smart community IoT access control device of the present application is coated with a layer of anti-scratch wear-resistant coating 14, which not only enhances the scratch resistance of the baffle, but also effectively reduces the friction resistance, thereby improving the user's experience. The anti-scratch wear-resistant coating 14 is evenly coated on the outer surface of the baffle by chemical spraying or physical deposition method, forming a protective layer that effectively prevents scratches and wear caused by external environment or physical contact during daily use. The coating has good adhesion and wear resistance, and can maintain its functional and appearance characteristics for a long time.

[0056] For example, to achieve this feature, advanced spray coating technology can be used during production to evenly spray a mixture of nano-sized aluminum oxide or silicon dioxide particles on the surface of the baffle, forming a strong and smooth coating. This step is usually completed in professional spray equipment, ensuring that the coating is uniform, bubble-free and crack-free, thereby achieving the best protection effect. Specifically, the coating thickness can be controlled between 5-20 microns to ensure that it can provide sufficient protection without affecting the overall appearance and feel of the baffle.

[0057] In one embodiment, the elastic return member 6 of the smart community IoT access control device of the present application includes a spring and a shock-absorbing cushion 15. The spring is used to provide elastic restoring force, while the shock-absorbing cushion 15 reduces the transmission of impact force when the impact-resistant baffle 4 is impacted, ensuring that the impact-resistant baffle 4 can quickly reset and maintain normal working condition. One end of the spring is fixed to the internal frame of the access control device, and the other end is connected with the impact-resistant baffle 4. The shock-absorbing cushion 15 is arranged between the spring and the impact-resistant baffle 4, effectively absorbing and releasing impact force, protecting the internal structure from damage.

[0058] In one embodiment, specifically, the spring is installed on the inner side of the access control device through a fixed support, which is fixed to the internal frame by screws. The shock-absorbing cushion 15 is installed on the inner side of the impact-resistant baffle 4, tightly adhering to the impact-resistant baffle 4 and connected with one end of the spring. When external impact acts on the impact-resistant baffle 4, the spring absorbs part of the impact force by compression, while the shock-absorbing cushion 15 further disperses the impact force, preventing damage caused by force concentration. This design ensures the stability and reliability of the access control device in various external environments. For example, when a pedestrian or vehicle hits the impact-resistant baffle 4, the spring and shock-absorbing cushion 15 work together to ensure that the impact-resistant baffle 4 resets quickly and does not fail due to long-term deformation.

[0059] In actual operation, when the device is in use, first, the fixed frame 1 is firmly installed on the door frame, providing a stable foundation for the entire device. One end of the hinge assembly 2 is connected to the fixed frame 1, and the other end is connected to the door leaf, ensuring that the door leaf can be smoothly opened and closed, thus realizing the basic function of the door. When users need to enter the community, they can perform identity verification and door lock control through the lock core assembly 3, thus realizing the locking and unlocking functions of the door lock. In order to ensure the safety of the access control device, the anti-damage baffle 4 is arranged in front of the lock core assembly 3, which can effectively resist external impact force and protect the lock core assembly 3 from damage. If the door is subjected to external force impact exceeding the preset force, the sensing trigger piece 5 installed inside the anti-damage baffle 4 will be immediately activated and send a signal to the control system, triggering a safety alarm or taking other preventive measures. At the same time, the elastic reset piece 6 located between the anti-damage baffle 4 and the lock core assembly 3 can quickly return to the initial position after being impacted, ensuring that the anti-damage baffle 4 is always in the correct working position and ensuring the normal operation of the device. This multi-level safety design not only improves the anti-damage performance of the access control device, but also guarantees the convenience and safety of user access.

[0060] The exemplary systems and methods of this application have been specifically illustrated and described herein with the foregoing preferred modes of carrying out the systems and methods. Those skilled in the art will realize that various changes can be made to the embodiments of the systems and methods described herein without departing from the spirit and scope of the application as defined in the appended claims.
