Description

Technical Field

[0001] This utility model relates to an alarm sensor bracket, specifically an alarm sensor bracket for safety helmets, belonging to the field of safety protection equipment technology. Background Technology

[0002] Safety is always a top priority in construction operations. Generally, in addition to proper safety management, workers are required to wear safety helmets to protect their heads from falling objects or other hazards. However, traditional safety helmets are relatively simple, mostly providing only physical protection, and are insufficient for real-time monitoring of workers' safety status and hazard warnings in actual work scenarios.

[0003] In existing technologies, such as the helmet camera mounting bracket disclosed in announcement number CN218898524U, the mounting bracket is firmly fixed to the helmet, forming an integral part with it. Simultaneously, the camera is secured through mating parts, ensuring that even with violent shaking during operation, the camera will not fall off, offering advantages of safety and sturdiness. However, the aforementioned existing technical solutions have the following shortcomings: In actual working scenarios, the mounting brackets used for these cameras are insufficient to meet the needs of real-time safety monitoring and hazard warning for workers. For example, in complex construction sites, workers may unknowingly approach dangerous areas, or the helmet may fail to issue an alarm in time after impact, leading to accidents or delays in rescue. Furthermore, the cameras primarily rely on manual real-time monitoring, requiring personnel to continuously monitor multiple screens. Prolonged work can lead to fatigue, reducing reaction time to dangerous situations and potentially missing optimal warning and rescue opportunities. Summary of the Invention

[0004] The purpose of this invention is to provide an alarm sensor bracket for safety helmets to address the problem that the cameras in the above-mentioned devices mainly rely on manual real-time monitoring, and the monitoring personnel need to continuously monitor multiple monitoring screens. Long-term work can easily lead to fatigue, resulting in a decrease in reaction speed to dangerous situations and possible missing of the best early warning and rescue opportunity.

[0005] The present invention achieves the above objectives through the following technical solution: an alarm sensor bracket for a safety helmet, comprising a safety helmet body;

[0006] The helmet body has an inner liner frame inside, and the surface of the inner liner frame has multiple mounting screws. The inner liner frame is detachably installed inside the helmet body by mounting screws. The sensing module, alarm module and power module are installed in sequence in the gap between the inner top surface of the helmet body and the inner liner frame.

[0007] As a further improvement of this utility model: the sensing module includes an impact sensing unit and an environmental monitoring unit for monitoring the impact of the safety helmet and the working environment, respectively. The impact sensing unit uses an acceleration sensor, and the environmental monitoring unit includes a harmful gas sensor and a temperature sensor.

[0008] As a further improvement of this utility model: the side of the inner lining frame that fits against the head of the human body has a concave structure and fits against the contour of the head of the human body, and a cotton pad is provided on the side of the inner lining frame that fits against the head of the human body.

[0009] As a further improvement of this utility model: the alarm module includes an audible and visual alarm unit and a wireless communication unit, which are used to receive signals from the sensing module and issue audible and visual alarms and transmit alarm information to a remote monitoring terminal. The light of the audible and visual alarm unit is a high-brightness flashing light, which is installed on one side surface of the safety helmet body, and the sound is a high-decibel alarm sound.

[0010] As a further improvement of this utility model: the power module is used to provide power support for the entire alarm sensing bracket and has a power monitoring function. The power module uses a rechargeable battery and a battery charging port is provided on one side surface of the safety helmet body.

[0011] As a further embodiment of this utility model: the surface of the inner liner frame is provided with an arc-shaped groove, and two hinged sliders are slidably connected in the arc-shaped groove. The surfaces of the two hinged sliders are slidably connected with the same arc-shaped rod, which is fixedly installed in the arc-shaped groove. A spring is installed on the surface of the arc-shaped rod on the side of the two hinged sliders that is far apart from each other. One end of the spring abuts against the arc-shaped groove. The surfaces of the two hinged sliders are hinged with hinge rods, and the other ends of the two hinge rods are hinged with the same hinge seat. A universal ball head is fixedly installed on the surface of the hinge seat. The inner surface of the safety helmet body is provided with a ball groove that is adapted to the universal ball head, and the universal ball head is rotatably connected in the ball groove.

[0012] As a further improvement of this utility model: several rubber buffer rods are fixedly installed on the outer surface of the inner liner frame, and the other end of each rubber buffer rod abuts against the inner surface of the safety helmet body.

[0013] As a further improvement of this utility model: a ventilation hole is provided on one side surface of the safety helmet body, and a basalt fiber reinforcement layer is laminated on the base surface of the safety helmet body.

[0014] The beneficial effects of this utility model are:

[0015] This utility model effectively solves the problem of workers not realizing they are approaching dangerous areas in complex construction sites by using a combination of structures such as a safety helmet body, inner liner frame, rubber buffer rod, sensing module, alarm module, power module, flashing light, universal ball joint, hinge rod and spring. The environmental monitoring unit of the sensing module can monitor the concentration of harmful gases and temperature in the working environment in real time. Once the concentration exceeds the safe range, it will promptly transmit the signal to the alarm module, reminding workers to avoid danger through sound and light alarms, thus preventing safety accidents caused by workers not realizing the danger.

[0016] To address the issue of helmets failing to issue timely warnings after impact, the impact sensing unit of the sensing module uses an accelerometer to quickly capture impact signals and transmit them to the alarm module. The alarm module immediately activates the audible and visual alarms and remote information transmission to ensure that relevant personnel are informed of the situation as soon as possible, thus avoiding delays in rescue efforts.

[0017] By reducing reliance on manual monitoring via cameras, the alarm module's wireless communication unit can automatically transmit alarm information to the remote monitoring terminal, eliminating the need for monitoring personnel to continuously monitor the screen. This reduces the risk of decreased reaction speed due to human fatigue, ensuring that appropriate measures are taken at the optimal time for early warning and rescue, and improving the efficiency of safety management.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0026] Example 1

[0027] like Figures 1 to 6 As shown, an alarm sensor bracket for a safety helmet includes a safety helmet body 1;

[0028] The helmet body 1 has an inner liner frame 2 inside. The surface of the inner liner frame 2 is provided with multiple mounting screws 3. The inner liner frame 2 is detachably installed inside the helmet body 1 by means of the mounting screws 3. The sensing module 5, the alarm module 6 and the power module 7 are installed in sequence in the gap between the inner top surface of the helmet body 1 and the inner liner frame 2.

[0029] The inner liner 2 is detachably installed inside the helmet body 1 by multiple mounting screws 3. This connection method ensures that the inner liner 2 is firmly connected to the helmet body 1 and is not easy to loosen or fall off when subjected to external forces such as impact, providing stable support for the head. At the same time, the detachable design facilitates the installation, removal and replacement of the inner liner 2. When the inner liner 2 is damaged or needs maintenance, there is no need to disassemble the entire helmet, reducing maintenance costs and difficulty.

[0030] Furthermore, the sensing module 5 includes an impact sensing unit and an environmental monitoring unit for monitoring the impact of the safety helmet and the working environment, respectively. The impact sensing unit uses an acceleration sensor, and the environmental monitoring unit includes a harmful gas sensor and a temperature sensor.

[0031] The collaborative work of the impact sensing unit and the environmental monitoring unit enables the sensing module 5 to capture safety hazards in all aspects of the work process. Whether it is the physical impact on the safety helmet or the gas or temperature hazards in the working environment, they can be detected in time and converted into signals and transmitted to the alarm module 6. This buys time for subsequent audible and visual alarms and information transmission, so that relevant personnel can take quick countermeasures to reduce the probability of accidents or mitigate the losses caused by accidents.

[0032] Furthermore, the side of the inner liner 2 that fits against the head of the human body has a concave structure and conforms to the contour of the head. A cotton pad is provided on the side of the inner liner 2 that fits against the head of the human body.

[0033] The concave structure that conforms to the head contour, combined with the cotton pad, can distribute the impact force more evenly to various parts of the head when the helmet is hit or vibrated. This is achieved through the elastic deformation of the cotton pad and the close fit between the inner frame 2 and the head, reducing the risk of excessive local force and further enhancing the protection of the head, thus reducing injuries caused by impact.

[0034] Furthermore, the alarm module 6 includes an audible and visual alarm unit and a wireless communication unit, which are used to receive signals from the sensing module 5 and issue audible and visual alarms as well as transmit alarm information to a remote monitoring terminal. The light of the audible and visual alarm unit is a high-brightness flashing light 9, which is installed on one side surface of the safety helmet body 1, and the sound is a high-decibel alarm sound.

[0035] The audible and visual alarm unit primarily serves on-site personnel, alerting them to take immediate action to prevent the danger from escalating. The wireless communication unit, on the other hand, enables linkage with the remote management terminal, forming a dual safety protection system that combines on-site and remote monitoring. This dual alarm mechanism provides strong support for both the wearer's timely avoidance of danger and the efficient command and dispatch of management personnel, further enhancing the reliability of the entire safety protection system.

[0036] Furthermore, the power module 7 provides power support for the entire alarm sensing bracket and has a power monitoring function. The power module 7 uses a rechargeable battery and has a battery charging port 10 on one side surface of the helmet body 1.

[0037] When the battery is low, the alarm module 6 can promptly send a notification to the wearer or remote monitoring terminal, reminding relevant personnel to charge the battery in time. This avoids the situation where the entire alarm sensor bracket fails due to the battery running out of power, ensuring that the device is always in normal working condition during operation and will not miss any danger signals, providing continuous and reliable power protection for the safety of the staff.

[0038] Example 2

[0039] Improvements based on Example 1:

[0040] Furthermore, the surface of the inner liner 2 is provided with an arc-shaped groove 11, and two hinged sliders 18 are slidably connected in the arc-shaped groove 11. The surfaces of the two hinged sliders 18 are slidably connected with the same arc-shaped rod 16. The arc-shaped rod 16 is fixedly installed in the arc-shaped groove 11. Springs 17 are installed on the surface of the arc-shaped rod 16 on the side of the two hinged sliders 18 that are far apart from each other. One end of the spring 17 abuts against the arc-shaped groove 11. The surfaces of the two hinged sliders 18 are hinged with hinge rods 15. The other ends of the two hinge rods 15 are hinged with the same hinge seat 12. A universal ball head 13 is fixedly installed on the surface of the hinge seat 12. The inner surface of the safety helmet body 1 is provided with a ball groove 14 that is adapted to the universal ball head 13. The universal ball head 13 is rotatably connected in the ball groove 14.

[0041] When the helmet is subjected to an external impact, the impact force is transmitted to the helmet body 1 and then to the universal ball joint 13. Since the universal ball joint 13 can rotate flexibly within the ball groove 14, it can first buffer the impact force to a certain extent and disperse the impact force to different directions. At the same time, the hinge seat 12 drives the hinge slider 18 to slide on the arc rod 16 through the hinge rod 15. At this time, the two hinge sliders 18 move away from each other and compress the springs 17 on both sides. The springs 17 have good elastic deformation ability and can convert part of the impact kinetic energy into elastic potential energy, thereby effectively absorbing and buffering the impact force, greatly reducing the magnitude of the impact force transmitted to the head, and playing a significant shock absorption and protection role. Moreover, the arc design of the arc rod 16 and the arc groove 11 is adapted to the arc contour of the head, making the force transmission and dispersion more in line with the force characteristics of the human head, and can evenly disperse the impact force to a larger area, avoiding excessive local force and causing injury to the head, further improving the protection effect for the head.

[0042] Furthermore, several rubber buffer rods 4 are fixedly installed on the outer surface of the inner liner frame 2, and the other end of each rubber buffer rod 4 abuts against the inner surface of the helmet body 1.

[0043] When the helmet body 1 is subjected to external impact, the impact force will first act on the helmet body 1, and then be transmitted to the inner liner frame 2 through the rubber buffer bar 4. During this process, the rubber buffer bar 4 will undergo elastic deformation, absorbing part of the impact energy and converting it into its own elastic potential energy, thereby effectively slowing down the transmission of the impact force to the head and further enhancing the cushioning and shock absorption effect of the helmet. Together with the arc groove 11 and other structures mentioned earlier, it forms multiple buffer protection, greatly reducing the risk of head injury.

[0044] Furthermore, a ventilation hole 8 is provided on one side surface of the helmet body 1, and a basalt fiber reinforcement layer is laminated on the base surface of the helmet body 1.

[0045] The ventilation holes 8 effectively promote air circulation between the inside and outside of the helmet. When workers wear helmets for extended periods, their heads generate heat and sweat. The ventilation holes 8 expel the hot air from inside and introduce fresh air from outside, reducing the internal temperature of the helmet, minimizing stuffiness, keeping the head dry, and significantly improving wearing comfort. This prevents discomfort caused by prolonged stuffiness from affecting work performance. The basalt fiber reinforcement layer has high strength and high modulus. When combined with the base surface of the helmet body 1, it significantly improves the overall structural strength and impact resistance of the helmet body 1. When the helmet is impacted by external forces, the basalt fiber reinforcement layer can effectively resist deformation, absorb and disperse impact energy, reduce the degree of damage to the helmet body 1, provide a more robust barrier for the head, enhance the core protective performance of the helmet, and reduce the risk of head injury.

[0046] Working principle: When the staff wears the safety helmet and enters the work area, the entire alarm sensor bracket will start to work. The power module 7 provides power to all electrical components such as the sensor module 5 and the alarm module 6. Its power monitoring function monitors the battery power in real time. When the power is low, the alarm module 6 will send the power information back to the wearer and the remote monitoring terminal to remind them to charge the battery through the charging port 10 in time.

[0047] The sensing module 5 is always in working condition. The accelerometer of the impact sensing unit continuously monitors the acceleration changes of the safety helmet. When the safety helmet is impacted, the acceleration will change abnormally. When the acceleration value exceeds the preset threshold, the impact sensing unit immediately transmits the signal to the alarm module 6. The hazardous gas sensor of the environmental monitoring unit continuously detects the concentration of hazardous gases in the working environment, and the temperature sensor monitors the ambient temperature in real time. Once the concentration of hazardous gases exceeds the set standard or the ambient temperature exceeds the safe range, the environmental monitoring unit will send the corresponding signal to the alarm module 6.

[0048] After receiving a danger signal from the sensing module 5, the alarm module 6 will react quickly. The high-brightness flashing light 9 of the sound and light alarm unit will emit a strong flashing light, and the high-decibel alarm will emit a loud alarm sound to attract the attention of the wearer and the surrounding people and remind them to avoid danger. At the same time, the wireless communication unit will transmit detailed alarm information, such as impact intensity, type and concentration of harmful gas, ambient temperature, etc., to the remote monitoring terminal through the wireless network, so that the management personnel can grasp the situation on site in a timely manner and take corresponding rescue, evacuation or rectification measures based on the alarm information.

[0049] In addition, the buffer structure composed of the arc groove 11, hinge slider 18, arc rod 16, spring 17, hinge rod 15, hinge seat 12, universal ball head 13 and ball groove 14 on the inner liner frame 2, as well as the rubber buffer rod 4, can effectively absorb and buffer the impact force when the helmet is hit, through the extension and contraction of the spring 17, the rotation of the universal ball head 13 and the elastic deformation of the rubber buffer rod 4, and reduce the injury to the head from the impact. The concave structure, cotton pad and ventilation hole 8 of the inner liner frame 2 always ensure the comfort of the wearer.

[0050] The basalt fiber reinforcement layer on the surface of the helmet body 1, with its high strength properties, continues to play a role throughout the working process, enhancing the helmet's impact resistance and providing solid protection for the head.
