Description

Technical Field

[0001] The utility model relates to the technical field of building safety equipment, in particular to an anti-collision device for doors and windows. Background Art

[0002] In modern buildings, doors and windows are important components that not only provide lighting and ventilation, but also directly affect the safety of the building and the comfort of living. However, in daily use or under special weather conditions (such as strong winds, earthquakes, etc.) or other unexpected situations, foreign objects may bump into or hit the windows, causing damage to the door and window frames or glass, or even causing harm to people. Traditional door and window protection measures mostly rely on physical locking systems. Although they can prevent illegal intrusions into doors and windows to a certain extent, they have limited protection against unexpected collisions caused by external forces.

[0003] In recent years, with the development of smart home technology, intelligent and automated door and window protection devices have begun to receive attention. These devices usually integrate sensors, control systems and actuators, can monitor the status of doors and windows in real time, and take measures to reduce the impact when possible impact risks are detected, thereby effectively protecting doors and windows and improving residential safety. Although a variety of intelligent protection devices have been launched, there are still problems such as slow response speed, unsatisfactory protection effect, and high maintenance cost. In particular, there is still much room for improvement in the precise control of the deployment and recovery of anti-collision nets and stable operation in complex environments. Utility Model Content

[0004] In view of the above problems, the purpose of the present invention is to provide a door and window anti-collision device with rapid response capability, efficient anti-collision effect, and integrated intelligent monitoring function.

[0005] Provided is a door and window anti-collision device, comprising: a camera device, a base, a rotating shaft, an anti-collision net, a metal counterweight, an electromagnet and a controller;

[0006] The camera device is electrically connected to the controller and mounted on the base;

[0007] The rotating shaft is rotatably mounted on the base;

[0008] One end of the anti-collision net is fixedly connected to the side surface of the rotating shaft; the anti-collision net can be wound around the rotating shaft;

[0009] The other end of the anti-collision net is fixedly connected with a metal counterweight;

[0010] When the anti-collision net is wound on the rotating shaft, the electromagnet is arranged at a position close to the metal counterweight block;

[0011] The electromagnet is electrically connected to the controller.

[0012] Furthermore, it also includes a handle, which is connected to one end of the rotating shaft, and the rotating shaft can be rotated synchronously by rotating the handle.

[0013] Furthermore, a plurality of reinforcing ribs are arranged at intervals on the anti-collision net.

[0014] Furthermore, the length direction of the reinforcing rib is parallel to the axis of the rotating shaft.

[0015] Furthermore, the mass of the metal counterweight block is greater than the mass of the anti-collision net.

[0016] Furthermore, the camera device includes a plurality of cameras, and the plurality of cameras are electrically connected to the controller respectively.

[0017] Further, two bearings are included;

[0018] The two bearings are spaced apart, and their outer sides are fixedly connected to the base;

[0019] The two ends of the rotating shaft are respectively inserted into the two bearings.

[0020] Furthermore, it also includes a shock-absorbing sheet,

[0021] The shock absorbing sheet is arranged on the side of the metal counterweight block close to the window.

[0022] Furthermore, it also includes a camera device protective cover, which is a hollow structure and covers the camera device therein.

[0023] Furthermore, the base is a flat plate structure.

[0024] The embodiments of the present invention have the following advantages or beneficial effects:

[0025] 1. By integrating the camera device and the controller, real-time monitoring of the door and window area is achieved, which can not only warn of possible collision events in advance, but also respond quickly when a collision occurs, effectively reducing or even avoiding damage. This combination of intelligent monitoring and physical protection has greatly improved the intelligent level of door and window security protection.

[0026] 2. The anti-collision net design combines metal counterweights and electromagnet control, which can be automatically and quickly deployed as needed. It not only ensures the beauty of doors and windows when not in use and does not obstruct the line of sight, but can also be quickly deployed at critical moments to form an effective anti-collision barrier and reduce damage caused by external force collisions.

[0027] 3. As the metal counterweight is heavy and relies on its gravity to complete the process, the metal counterweight may hit the window frame and glass during the process and when foreign objects hit the anti-collision net. Therefore, a shock-absorbing sheet is set on the side of the metal counterweight close to the window to effectively absorb the vibration energy generated by the collision and protect the door and window frames from damage.

[0034] Figure 1 This is a schematic diagram of a door and window anti-collision device provided by an embodiment of the utility model. The above schematic diagram is not intended to be the actual scale of the actual product.

[0035] like Figure 1 As shown, a door and window anti-collision device according to an embodiment of the utility model includes: a camera device 1, a base 2, a rotating shaft 3, an anti-collision net 4, a metal counterweight block 5, an electromagnet 6 and a controller.

[0036] Among them, the base 2 is an important part of the door and window anti-collision device. Its structural design and material selection are directly related to the stability, durability and installation convenience of the entire device. In this technical solution, the base 2 adopts a series of carefully designed features to meet the above requirements:

[0037] Structural design

[0038] Flat plate structure: The base 2 is designed as a flat plate structure, which ensures that it can be firmly installed on the door and window frames, whether the window frames are made of metal, wood or other materials. The size of the flat plate structure is suitable for a variety of door and window sizes. Through the preset installation holes, it is tightly connected to the door and window frames using screws or other fasteners, or it is tightly connected to the door and window frames by magnetic attraction or bonding, ensuring that the device will not shake or fall off due to external forces.

[0039] Multifunctional integrated platform: The base 2 is not only the supporting foundation of the device, but also the integrated platform of each component. It has a special installation position and interface for fixing key components such as the camera device 1, the shaft 3 bearing 7, and the electromagnet 6, ensuring the orderly arrangement of each part, which not only ensures the coordinated operation of the equipment, but also simplifies the installation process.

[0040] Reinforced rib structure: A reinforced rib structure may be designed inside or on the back of the base 2 to enhance its own mechanical properties, prevent deformation caused by the device's own weight or external impact, and ensure stability during long-term use.

[0041] Material selection

[0042] Weather-resistant materials: Considering that the door and window anti-collision device may be exposed to different climatic conditions, the base 2 material must have good weather resistance, such as stainless steel, aluminum alloy or specially treated engineering plastics. These materials are not only corrosion-resistant and aging-resistant, but also can withstand temperature changes without deformation.

[0043] Lightweight design: In order to facilitate installation and reduce the burden on door and window frames, the material selection of base 2 tends to be lightweight and high-strength materials, such as aviation aluminum or carbon fiber composite materials, which can not only ensure the firmness of the structure but also reduce the overall weight.

[0044] Environmental protection and sustainability: Environmental factors will also be taken into consideration when selecting materials, and recyclable materials will be selected to reduce the impact on the environment and meet the requirements of modern green buildings.

[0045] In summary, the structure and material design of the base 2 are centered around improving the overall performance, stability, and durability of the device, while taking into account the convenience and environmental friendliness of installation, ensuring that the door and window anti-collision device can perform at its best in various application environments.

[0046] The connection and installation method between the base 2 and the window is an important part to ensure the stability and reliability of the door and window anti-collision device. The specific implementation method is as follows:

[0047] Installation

[0048] Positioning mark: First, use a level and ruler to accurately measure and mark the window frame to determine the installation position of the base 2. Ensure that the base 2 does not affect the normal opening and closing of the window after installation, and can effectively cover the anti-collision area.

[0049] Embedded parts installation: For some materials (such as concrete, brick wall), expansion bolts or other types of embedded parts may need to be pre-installed. This step is usually completed before the window is installed or during the decoration stage to ensure the firmness of the base 2 installation.

[0050] Alignment of fixing holes: Place the base 2 at the predetermined position, ensuring that the mounting holes on it are aligned with the marks or embedded parts on the window frame. Some designs may allow a certain adjustment range to facilitate fine-tuning of the installation position.

[0051] Fastening connection: Use appropriate screws or bolts to pass through the mounting holes on the base 2 and fasten it to the window frame or embedded parts. During the fastening process, it may be necessary to proceed in steps, first perform preliminary fastening, then check whether the base 2 is level, adjust it if necessary, and finally fully tighten all fixing screws to ensure that the base 2 is firm and does not shake.

[0052] In addition, it can also be installed by magnetic suction and adhesive.

[0053] Magnetic installation: For metal window frames, the back of the base 2 can be designed to embed strong magnets or magnetic patches. These magnets need to be strong enough to ensure that the base 2 is stably attached to the window frame during daily use, and also easy to remove for cleaning or maintenance. Place the base 2 close to the window frame and find the most suitable attachment position to ensure that the anti-collision device can effectively cover and protect the window. Once the position is determined, just press lightly and use the magnetic force to naturally attach and fix. To enhance stability, auxiliary buckles or rubber gaskets can be designed at the four corners or key positions of the base 2 to increase friction and prevent sliding.

[0054] Adhesive installation: For windows made of non-metallic materials or where magnetic attraction is not desired, high-strength, weather-resistant double-sided tape or special construction adhesives can be used. This type of adhesive must ensure good adhesion under different temperature and humidity conditions, and be easy to remove safely when needed without damaging the window frame. Before formally pasting, the contact surface of the window frame must be thoroughly cleaned to remove dust, grease, etc., and ensure that the bonding surface is clean and dry. Subsequently, cut the appropriate length of double-sided tape according to the size of the base 2 or evenly apply the adhesive to the back of the base 2, align it with the pre-marked position, and apply pressure slowly and evenly to ensure that the bonding surface is fully in contact without bubbles. It is recommended to let it stand for a period of time after pasting (according to the adhesive instructions) to allow the adhesive to fully cure and achieve the best bonding effect.

[0055] In practical applications, the most suitable installation method can be flexibly selected according to the window material and user preferences, or even a combination of multiple installation methods. In either case, it is necessary to ensure that the base 2 is installed firmly and horizontally, and does not hinder the normal operation of the window. The introduction of magnetic attraction and bonding technology not only simplifies the installation process and reduces the changes to the window structure, but also provides users with more diverse installation options, further improving the popularity and practicality of door and window anti-collision devices.

[0056] The rotating shaft 3 rotates on the base 2. Specifically, it also includes two bearings 7; the two bearings 7 are arranged at intervals, and the outer sides thereof are fixedly connected to the base 2; and the two ends of the rotating shaft 3 are respectively inserted into the two bearings 7.

[0057] The connection between the rotating shaft 3 and the base 2 is achieved through two bearings 7. This design detail is crucial to the stability and service life of the entire door and window anti-collision device. The following is a detailed description of this structure and an analysis of its functions and beneficial effects:

[0058] Structural Description

[0059] Selection and layout of bearings 7: The two bearings 7 are usually rolling bearings 7, such as deep groove ball bearings 7 or cylindrical roller bearings 7, because they have the characteristics of low friction, high load capacity and long life. They are arranged at intervals, and the shaft 3 is installed between them. Such a layout ensures that the shaft 3 can be evenly stressed when rotating to avoid single-point wear.

[0060] Bearing 7 fixing method: The outer ring of the bearing 7 is firmly connected to the preset hole of the base 2 by screws, pins or special fixing parts, or welded. This design ensures that the bearing 7 is stably fixed on the base 2, and the bearing 7 will not deviate or fall off even if the shaft 3 is subjected to a large torque or external force impact.

[0061] Insertion method of shaft 3: Both ends of shaft 3 are designed with journals that accurately match the inner diameter of bearing 7. Precision machining ensures that shaft 3 can be smoothly inserted into two bearings 7 and maintain appropriate radial and axial clearances, so as to avoid being too tight to increase rotational resistance, or too loose to cause shaking.

[0062] Effects and beneficial effects

[0063] Reduce friction and wear: The use of the bearing 7 greatly reduces the friction between the rotating shaft 3 and the base 2, thereby reducing the energy loss during rotation and extending the service life of the rotating shaft 3 and the entire device.

[0064] Improved stability and precision: The bearing 7 supports the coaxiality of the shaft 3, and can maintain stable rotation of the shaft 3 even in continuous or long-term operation, thereby avoiding uneven winding or abnormal unfolding of the anti-collision net 4 caused by vibration or uneven force.

[0065] Enhanced load-bearing capacity: The two bearings 7 share the weight and external force borne by the rotating shaft 3, effectively improving the load-bearing capacity of the entire device, so that the device can still maintain a good working condition when encountering sudden strong winds, collisions, etc., and effectively protect doors and windows.

[0066] Simplified maintenance: Since the bearing 7 is a standard part, if it needs to be replaced or repaired in the future, the operation is relatively simple, and there is no need to disassemble the entire device on a large scale, which reduces the maintenance cost and difficulty.

[0067] In summary, the design of supporting the rotating shaft 3 by using two bearings 7 arranged at intervals not only improves the mechanical performance and durability of the door and window anti-collision device, but also simplifies the maintenance process, which is an efficient and practical structural design solution.

[0068] One end of the anti-collision net 4 is fixedly connected to the side surface of the rotating shaft 3; the anti-collision net 4 can be wound around the rotating shaft 3. The details are as follows:

[0069] Fixed connection method: One end of the anti-collision net 4 is usually connected to the side surface of the rotating shaft 3 by welding, bolting, riveting or special fixing fixtures to ensure that it will not be separated from the rotating shaft 3 under any circumstances. This connection must ensure that it is both firm and reliable and does not hinder the free winding of the anti-collision net 4.

[0070] Anti-collision net 4 material and design: Anti-collision net 4 itself is made of materials with certain elasticity and toughness, such as high-strength nylon net, polyester fiber or special rubber fabric, which can absorb impact energy and have sufficient wear resistance and weather resistance. The mesh surface design often has certain pores to reduce its own weight while not hindering vision and light penetration.

[0071] Winding mechanism: When the device is not activated, the anti-collision net 4 is tightly wound around the rotating shaft 3, taking up little space and not affecting the normal use and appearance of the window. Once it needs to be unfolded, the controller controls the electromagnet 6 to lose power, so that the electromagnet 6 and the metal counterweight 5 at the bottom of the anti-collision net 4 are separated without magnetic attraction, and the rotating shaft 3 is rotated by the gravity of the metal counterweight 5 and the anti-collision net 4, and the anti-collision net 4 is unfolded along the rotating shaft 3 to form a protective barrier.

[0072] Effects and beneficial effects

[0073] Instant Response and Protection: This design enables the anti-collision net 4 to be deployed instantly, responding quickly to impending collision events, effectively absorbing and dispersing the impact force, and protecting doors and windows from damage.

[0074] Space saving and aesthetics: In the non-working state, the anti-collision net 4 is tightly wound around the rotating shaft 3, which not only saves space, but also keeps the door and window area clean and beautiful without affecting the visual permeability between indoor and outdoor areas.

[0075] Easy to maintain and replace: The replaceable design of the anti-collision net 4 means that if the net surface is damaged or aged, you only need to untie the fixed end to easily replace the new anti-collision net 4, which reduces the maintenance cost and difficulty.

[0076] Strong adaptability: Anti-collision nets 4 of different lengths and materials can be customized according to the actual size of the window and environmental requirements, so that the device can be widely used in various types of doors and windows, improving the flexibility and universality of application.

[0077] To sum up, the fixed connection and winding design between the anti-collision net 4 and the side surface of the rotating shaft 3 not only realizes the rapid response and efficient protection of the device, but also takes into account the aesthetics, maintenance convenience and wide application scenarios. It is one of the core innovations of the door and window anti-collision device.

[0078] The other end of the anti-collision net 4 is fixedly connected with a metal counterweight 5, which is the key to realize the automatic deployment and recovery functions. Its connection method usually involves the following details and technical points:

[0079] Structural connection method

[0080] Direct fixing method: The most direct way is to fix the metal counterweight 5 directly to the end of the anti-collision net 4 by welding, bolt connection or embedded design. This method has a simple structure and high strength, ensuring that the counterweight is firmly connected to the anti-collision net 4 and is not easy to fall off.

[0081] Adjustable connector: In order to adapt to different lengths of the anti-collision net 4 or adjust the balance point, a connector with an adjustment mechanism can be used. For example, a threaded metal rod is used to connect the counterweight block and the anti-collision net 4, and the distance between the two is adjusted through a nut, so as to fine-tune the balance state of the system and optimize the efficiency of deployment and recovery.

[0082] Elastic connection components: In some designs, springs, rubber bands or other elastic elements may be used as connection media. The purpose of this is to increase the flexibility of the system, allowing the anti-collision net 4 to have a certain buffer space when it is slightly hit, while ensuring that the counterweight block can smoothly tighten the anti-collision net 4 during the retraction process to avoid sudden pulling damage.

[0083] The firm connection structure ensures the integrity of the anti-collision net 4 during long-term use, reduces failures caused by loose connections, and ensures the long-term stable operation and effective protection effect of the device.

[0084] In short, the connection design between the anti-collision net 4 and the metal counterweight 5 is one of the core elements to achieve the automated operation and efficient protection performance of the door and window anti-collision device, and the rationality of its structure is directly related to the reliability and service life of the entire system.

[0085] When the anti-collision net 4 can be wound on the rotating shaft 3, an electromagnet 6 is arranged at a position close to the metal counterweight 5. The electromagnet 6 is electrically connected to the controller.

[0086] In the anti-collision device, an electromagnet 6 is arranged near the metal counterweight 5 and electrically connected to the controller, which is a sophisticated design to achieve more precise control and automatic operation. The specific description and functions and benefits are as follows:

[0087] Structural Description

[0088] Installation position of electromagnet 6: electromagnet 6 is carefully placed on the path of anti-collision net 4 near rotating shaft 3, and its relative position with metal counterweight 5 is calculated to ensure that electromagnet 6 can accurately interact with the counterweight when anti-collision net 4 is retracted.

[0089] Interaction between electromagnet 6 and counterweight: Metal counterweight 5 contains enough ferromagnetic material to be attracted or released by electromagnet 6. Electromagnet 6 is controlled by the controller through the circuit, and can be powered on or off at the right time to change its magnetic field state, thereby controlling the movement of the counterweight.

[0090] Electrical connection and control logic: The electromagnet 6 is connected to the controller through wires. The program or algorithm built into the controller determines when to start or shut down the electromagnet 6 based on the sensor (such as the information monitored by the camera) to achieve automatic deployment operation. For example, when strong winds or objects approaching doors and windows are detected, the controller de-energizes the electromagnet 6 and then separates it from the metal counterweight 5. The counterweight pulls the anti-collision net 4 by gravity, so that the anti-collision net 4 is quickly deployed.

[0091] Effects and Benefits

[0092] Automatic control: The linkage between the electromagnet 6 and the controller realizes the automatic control of the anti-collision net 4 without manual intervention, thereby improving the reaction speed and convenience of use.

[0093] Precise operation: Through the precise control of the electromagnet 6, the deployment action of the anti-collision net 4 can be quickly controlled, thereby improving the protection efficiency.

[0094] Enhanced safety: Automated control reduces the possibility of human operating errors, especially in emergency situations, and can respond quickly to effectively protect doors and windows and prevent accidents.

[0095] Easy maintenance: The electromagnet 6 components are relatively independent. If a fault occurs, it is easy to diagnose and replace, and the maintenance cost is low.

[0096] In summary, the interactive design of the electromagnet 6 and the metal counterweight 5 not only improves the automation level and protection efficiency of the door and window anti-collision device, but also embodies the design concept of intelligence, energy saving and easy maintenance, which is a highlight of the technical solution.

[0097] The mass of the metal counterweight 5 is greater than that of the anti-collision net 4. Since the metal counterweight 5 is of a large mass, when the anti-collision net 4 needs to be deployed, its gravity is overcome, so that the anti-collision net 4 can be deployed quickly and smoothly under the traction of the counterweight. This design uses natural gravity as a driving force and does not require continuous power support, which improves the energy efficiency and adaptability of the system. It can be recovered normally even in a power outage, increasing the reliability of the system. The design is simple, without complex mechanical structures, reducing failure points, reducing maintenance costs and difficulties, and users can operate it easily, improving the overall user experience.

[0098] A plurality of reinforcing ribs are arranged at intervals on the anti-collision net 4. The length direction of the reinforcing ribs is parallel to the axis of the rotating shaft 3. This is a strategy for enhancing the structural strength and stability of the anti-collision net 4.

[0099] Specific description

[0100] Layout of reinforcing ribs: The reinforcing ribs are usually made of high-strength materials that are the same as or compatible with the anti-collision net 4, in strip shape, and are arranged at intervals on the surface or inside of the entire anti-collision net 4. Such a layout is intended to enhance the overall rigidity and tensile resistance of the anti-collision net 4 without significantly increasing its weight.

[0101] Parallel to the axis of the rotating shaft 3: The reinforcing ribs are arranged along the longitudinal direction of the anti-collision net 4, that is, their length direction is parallel to the central axis of the rotating shaft 3. This arrangement can effectively resist the tensile stress caused by external force when the anti-collision net 4 is unfolded, especially during the rotation and unfolding process of the rotating shaft 3, which helps to keep the net surface flat and stable in shape.

[0102] Effects and Benefits

[0103] Improve impact resistance: The reinforcement ribs increase the local and overall strength of the anti-collision net 4, so that it can better absorb and disperse the impact force when it is hit, reduce the risk of damage, and protect the door and window structure.

[0104] Maintaining structural stability: The layout of the reinforcing ribs parallel to the axis of the rotating shaft 3 helps to maintain the straight shape of the anti-collision net 4 when it is deployed, prevents twisting or wavy deformation, and ensures maximum anti-collision effect.

[0105] Prolong service life: The addition of reinforcing ribs reduces fatigue damage caused by repeated stretching and compression of a single material, and improves the durability and service life of the anti-collision net 4.

[0106] Optimized deployment and recovery: Structural reinforcement allows the anti-collision net 4 to move more smoothly during deployment and recovery, reducing the risk of jamming or entanglement, and improving the overall working efficiency of the device.

[0107] Through such a design, the anti-collision net 4 can not only provide more reliable protection in the face of sudden collisions, but also show higher economy and reliability in daily maintenance and use cycle. It is an indispensable structural reinforcement measure in the door and window anti-collision device.

[0108] The camera device 1 is electrically connected to the controller and mounted on the base 2 .

[0109] The design that the camera device 1 is electrically connected to the controller and mounted on the base 2 plays a vital role in the door and window anti-collision device. The specific description and functions and benefits are as follows:

[0110] Specific description

[0111] Integration of camera device 1: The camera device 1 is usually one or more high-definition cameras, which are installed at appropriate positions on the base 2 to facilitate all-round or directional monitoring of the door and window area. These cameras may have functions such as night vision, wide dynamic range, and high resolution to ensure clear capture of images under various lighting conditions.

[0112] Electrical connection: The camera device 1 is electrically connected to the controller via a wired (such as USB, Ethernet) or wireless (such as Wi-Fi, Bluetooth) connection. This connection ensures stable transmission of video data, and the controller can receive and process image information from the camera in real time.

[0113] Installation location and fixation: The installation location of the camera device 1 on the base 2 is carefully designed to ensure a wide field of view and cover the key areas of doors and windows, while avoiding blocking or affecting the normal use of doors and windows. The installation method may include screw fixation, buckle locking, etc. to ensure that the camera is stable and does not shake.

[0114] Effects and Benefits

[0115] Real-time monitoring: The camera device 1 can continuously monitor the environment around the doors and windows, and feed back images to the controller in real time, so that the system can respond to external threats in a timely manner, such as detecting a person or object approaching the doors and windows, and prepare anti-collision measures in advance.

[0116] Intelligent analysis: Based on the image information provided by the camera, the controller can analyze and determine whether there is a potential collision risk through the built-in image recognition algorithm, such as identifying fast-moving objects or abnormal wind conditions, so as to actively control the deployment or recovery of the anti-collision net 4.

[0117] Remote management and alarm: Integration with the intelligent system also allows remote viewing of monitoring images. Through mobile phone APP or other remote terminals, users can know the status of doors and windows at any time. In case of emergency, the system can notify users through SMS, phone or APP push, etc., to enhance safety.

[0118] Evidence retention: The video data recorded by the camera device 1 can be used for accident analysis or evidence retention to help trace the cause of the accident afterwards, which is extremely important whether it is used for insurance claims or the formulation of safety improvement measures.

[0119] Crime prevention: In addition to the anti-collision function, the presence of the camera itself is also an effective deterrent, which can effectively prevent crimes such as theft and vandalism, and improve the overall security level.

[0120] Through this design, the door and window anti-collision device not only enhances the physical protection capability, but also integrates intelligent monitoring and early warning functions, providing users with a more comprehensive and intelligent security protection solution.

[0121] It also includes a camera device protective cover (not shown in the figure), which is a hollow structure and covers the camera device 1 therein.

[0122] The design of the camera protection cover is also a highlight of the safety system, especially the hollow structure design. Its specific description, functions and benefits are as follows:

[0123] Specific description

[0124] Hollow structure design: The camera device protective cover adopts a hollow structure, which means that it is not a completely closed shell, but is designed with regular holes or grid patterns. Such a design can not only ensure that light can reach the camera lens unimpeded and ensure the clarity of the video image, but also to a certain extent block the interference of direct physical contact and external environmental factors on the camera device 1.

[0125] Material selection: The protective cover is usually made of durable and lightweight materials such as aluminum alloy, engineering plastic or stainless steel. These materials have good weather resistance and corrosion resistance, suitable for indoor and outdoor use. At the same time, the hollow design also reduces the overall weight.

[0126] Ease of installation: The design of the protective cover takes into account the compatibility with the camera device 1 and the base 2, and is usually equipped with a fixing device that is easy to install and adjust, ensuring that the viewing angle of the camera device 1 can still be flexibly adjusted when installed in the protective cover to meet different monitoring needs.

[0127] Effects and Benefits

[0128] Protecting the camera device 1: The hollow protective cover can effectively prevent the camera device 1 from being damaged by accidental collision, human damage or natural factors (such as bird droppings, fallen leaves), thereby extending the service life of the device.

[0129] Maintain a clear view: The hollow design keeps the image clear and ensures that the monitoring effect is not affected.

[0130] Beautification and concealment: In some cases, the hollow structure can also provide a certain decorative effect, making the security equipment more coordinated with the surrounding environment. At the same time, appropriate hollow design can increase concealment and reduce interference with people's daily vision without hindering the monitoring efficiency.

[0131] Ventilation and heat dissipation: For the camera device 1 that needs to run for a long time, the hollow structure is conducive to air circulation, improves heat dissipation efficiency, reduces equipment failures caused by overheating, and ensures stable operation of the system.

[0132] In summary, the hollow design of the camera device protective cover not only ensures the safety of the camera device 1 and maintains the monitoring quality, but also takes into account the aesthetics and practicality, and is an indispensable part of the modern security system.

[0133] The device further includes a handle 8, which is connected to one end of the rotating shaft 3. The handle 8 can be turned to synchronously rotate the rotating shaft 3. The handle 8 is added to the door and window anti-collision device so that the user can manually intervene to control the rotation of the rotating shaft 3, thereby controlling the recovery of the anti-collision net 4, as follows:

[0134] Structure of handle 8: The handle 8 is usually designed to be a shape that is easy for human hands to hold, such as a round or ergonomically curved shape. It is installed at one end of the rotating shaft 3 and is tightly combined with the rotating shaft 3 through a mechanical connection (such as a thread, key connection or direct fixation) to ensure that the force can be directly and smoothly transmitted to the rotating shaft 3 when the handle 8 is turned.

[0135] Manual operation: When the collision net needs to be manually recovered, the user can hold the handle 8 and turn it by hand to drive the rotating shaft 3 to rotate. This design simplifies the operation process, and the anti-collision net 4 can be easily deployed or recovered without professional knowledge.

[0136] The working process of the entire door and window anti-collision device can be divided into several key steps, from daily standby state to response when encountering potential collision danger, and then to recovery. The specific process is as follows:

[0137] Standby mode

[0138] Monitoring start: The camera device 1 is started, electrically connected to the controller, and continuously monitors the environment around the doors and windows to capture images and video data.

[0139] The device is on standby: the anti-collision net 4 is tightly wound around the rotating shaft 3, and the metal counterweight 5 is located below, and the anti-collision net 4 is kept taut by gravity. The electromagnet 6 is in the on state, attracting the counterweight.

[0140] Hazard Detection and Response

[0141] Detection and analysis: The image data captured by the camera 1 is transmitted to the controller. Through the built-in image analysis algorithm, the system identifies whether there are objects approaching the doors and windows quickly or abnormal wind conditions, and determines whether there is a collision risk.

[0142] Automatic response: Once a potential collision risk is identified, the controller immediately sends a command to cut off the power of the electromagnet 6, so that it loses the attraction with the metal counterweight 5, and the metal counterweight 5 moves upward against gravity. At this time, the anti-collision net 4 is quickly deployed under the traction of the metal counterweight 5 to form a protective barrier.

[0143] Protection Phase

[0144] Anti-collision protection: When the anti-collision net 4 is fully deployed, it can effectively absorb and disperse the impact force, protecting the doors and windows from damage. The reinforcement rib design makes the anti-collision net 4 maintain a stable structure when subjected to force and is not easy to tear.

[0145] Danger elimination and recovery

[0146] Automatic recovery: After the collision risk is eliminated, the rotating shaft 3 can be rotated by the handle 8 so that the anti-collision net 4 is rewound around the rotating shaft 3 until it is completely recovered to the initial state.

[0147] Continue monitoring: The system returns to the standby state, and the camera device 1 continues to monitor the door and window area, waiting for the next instruction or automatic response trigger.

[0148] The entire working process reflects the intelligence, automation and user-friendliness of the device, ensuring that doors and windows can be protected promptly and effectively in the event of accidental collisions, while maintaining the convenience of daily use and low maintenance costs.
