[0057] Head-mounted alarm devices are devices that can quickly issue alerts in emergency situations, prompting nearby personnel and users to take action. These devices are widely used in high-risk work environments, such as construction sites, chemical plants, and tunnel construction sites, to provide users with early warning and protection.

[0058] Most existing head-mounted alarm devices adopt a fixed protective structure. Although this method can improve the protective capability of head-mounted alarms, they can only passively withstand impacts or dangers and are difficult to effectively adapt to sudden dangerous environments or emergencies, lacking active protection capabilities.

[0059] This invention proposes a head-mounted alarm device to improve the active protection capability of head-mounted alarm devices.

[0060] Please see Figures 1 to 3 In one embodiment, the head-mounted alarm device includes a housing 100, a protective component 200, an inflation component, a detection unit, a control system, and an alarm unit.

[0061] The housing 100 provides a mounting position for the structure of the head-mounted alarm device and provides passive protection. The outer surface of the housing 100 has mounting grooves, and the protective component 200 is movably mounted in the mounting groove. An inflation component is located between the protective component 200 and the mounting groove, and is used to drive the protective component 200 to move relative to the mounting groove so that it protrudes out of the mounting groove. In one embodiment, the outer surface of the housing 100 has three mounting grooves, respectively located on the top and sides of the housing 100, and three corresponding protective components 200 are provided. Each protective component 200 has an inflation component between it and a mounting groove, providing more comprehensive protection for the user. Of course, in other embodiments, the housing 100 may also have multiple mounting grooves, evenly distributed on the outer surface of the housing 100, with multiple corresponding protective components 200 and inflation components to achieve comprehensive protection; or the housing 100 may have only one mounting groove, with one corresponding protective component 200 and inflation component. Here, the number of mounting grooves and protective components 200 is not limited.

[0062] A detection unit is located in the housing 100. The control system is electrically connected to the detection unit and the inflation assembly, and the alarm unit is electrically connected to the control system. In one embodiment, the detection unit includes an accelerometer 520, which is used to detect the motion state of the head-mounted alarm device in real time. The accelerometer 520 can emit a real-time signal based on the speed change of the head-mounted alarm device and transmit the real-time signal to the control system. The control system has a preset safety signal range. The control system can determine whether the real-time signal is within the preset safety signal range, and thus determine whether the motion state is normal, that is, whether the head-mounted alarm device is in a dangerous situation. The detected motion state can be falling, rapid movement, etc., and the preset safety signal range can be flexibly set according to the actual situation, without limitation. In one embodiment, the detection unit also includes a position sensor 510, which is used to detect the real-time position of the head-mounted alarm device and transmit the real-time position to the control system. The control system has a danger zone range. The control system can determine whether the real-time position is within the danger zone range, and thus determine whether the head-mounted alarm device is in a dangerous situation. The danger zone range can be flexibly set according to the actual situation, without limitation. Of course, in other embodiments, the detection unit may also include a pressure sensor to detect the impact force of the head-mounted alarm device; therefore, no limitation is placed on the detection unit. The control system may employ a microcontroller, microprocessor, application-specific integrated circuit, or field-programmable gate array, etc.; no limitation is placed on this aspect.

[0063] Thus, when the control system determines that the head-mounted alarm device is in a dangerous situation based on the signal from the detection unit, the control system will control the inflation component to start, so as to push the protective component 200 to move away from the mounting slot and protrude from the mounting slot to provide additional physical protection; at the same time, the control system controls the alarm unit to issue an alarm signal to alert the user and surrounding personnel.

[0064] The technical solution of this utility model includes a housing 100, a protective component 200, an inflation component, a detection unit, a control system, and an alarm unit in a head-mounted alarm device. The outer surface of the housing 100 has a mounting groove, in which the protective component 200 is movably mounted. The inflation component is located between the protective component 200 and the mounting groove, and is used to drive the protective component 200 to move relative to the mounting groove so that it protrudes out of the groove. The detection unit is located in the housing 100. The control system is electrically connected to the detection unit and the inflation component. The alarm unit is electrically connected to the control system. Compared to existing head-mounted alarm devices with fixed protective structures, this utility model's technical solution includes an inflation component and a protective component 200. When the head-mounted alarm device is in a dangerous situation, the control system controls the alarm unit to issue an alarm while simultaneously controlling the inflation component to cause the protective component 200 to protrude out of the mounting groove, providing active protection and improving the active protection capability of the head-mounted alarm device.

[0065] Please see Figure 2 and Figure 3 In one embodiment, the protective component 200 includes a reinforcing rib 210 and a fixing structure. The reinforcing rib 210 is movably disposed in the mounting groove. The reinforcing rib 210 is hollow and has an opening on the side facing the mounting groove. The inflation component is disposed in the mounting groove and abuts against the reinforcing rib 210 through the opening. The fixing structure movably connects the reinforcing rib 210 and the mounting groove.

[0066] In one embodiment, the reinforcing ribs 210 are correspondingly provided with the mounting grooves, and the size of the reinforcing ribs 210 is adapted to the size of the mounting grooves, so that in the initial state, i.e., when the inflation assembly is not activated, the side of the reinforcing ribs 210 facing away from the bottom of the mounting groove is flush with the outer surface of the housing 100. Of course, in other embodiments, the height of the reinforcing ribs 210 may be greater than the depth of the mounting groove, so that in the initial state, the side of the reinforcing ribs 210 facing away from the bottom of the mounting groove protrudes from the outer surface of the housing 100. Here, no specific limitations are made on the size of the reinforcing ribs 210 and the mounting grooves.

[0067] In one embodiment, the fixing structure includes a first fixing member 221 and a second fixing member 222. The first fixing member 221 is disposed on the reinforcing rib 210 and is made of a magnetizable material. The second fixing member 222 is disposed at the bottom of the mounting groove and electrically connected to the control system. The second fixing member 222 is made of a magnetic conductor material. The control system controls the second fixing member 222 to be energized or de-energized, causing the second fixing member 222 to attract or separate from the first fixing member 221. The magnetizable material can be iron, steel, or other ferromagnetic materials, and the magnetic conductor material can be conductive materials such as copper or aluminum; no specific limitations are imposed. In one embodiment, the inner wall of the mounting groove and the inner wall of the reinforcing rib 210 are provided with a magnetic shielding coating to prevent the second fixing member 222 from affecting other structures of the head-mounted alarm device when energized. The magnetic shielding coating can be a non-conductive material with high magnetic permeability, such as ferrite, magnetic rubber, or nanocrystalline soft magnetic composite material; no limitations are imposed. In one embodiment, the fixing structure includes two first fixing members 221 and two second fixing members 222, which are respectively disposed at both ends of the reinforcing rib 210 and the mounting groove, with the first fixing members 221 and the second fixing members 222 corresponding one-to-one. Further, in one embodiment, the fixing structure also includes two elastic connectors 230, which are disposed at both ends of the mounting groove. One end of the elastic connector 230 is fixed to the bottom of the mounting groove, and the other end of the elastic connector 230 is connected to the reinforcing rib 210 to prevent the reinforcing rib 210 from dislodging from the mounting groove during movement. Of course, in other embodiments, the fixing structure may also include only one first fixing member 221, one second fixing member 222, and one elastic connector 230; or the fixing structure may also include a suction cup for movable connection through adsorption; the fixing structure may also include a telescopic rod to connect the mounting groove and the reinforcing rib 210. No limitations are imposed here.

[0068] When the control system energizes the second fixing member 222, the current flowing through it generates a magnetic field. The first fixing member 221 is magnetized by this magnetic field and thus attracted to the second fixing member 222, achieving adsorption. When the control system de-energizes the second fixing member 222, its magnetic field disappears, and without the attraction of a magnetic field, the first and second fixing members 221 separate. Thus, in the initial state, the control system energizes the second fixing member 222, causing it to attract the first fixing member 221 and thus securing the reinforcing rib 210. When the control system determines from the signal from the detection unit that the head-mounted alarm device is in a dangerous situation, it de-energizes the second fixing member 222, causing it to separate from the first fixing member 221. Simultaneously, the control system activates the inflation assembly to push the reinforcing rib 210 away from the mounting groove, causing it to protrude from the mounting groove.

[0069] The technical solution of this utility model embodiment, by setting a reinforcing rib 210, allows the reinforcing rib 210 to be hidden within the mounting groove in the initial state, reducing the size of the head-mounted alarm device. By setting a fixing structure, the reinforcing rib 210 can be fixed to the mounting groove in the initial state, and the fixing structure is controlled by a control system. This allows the reinforcing rib 210 to separate from the mounting groove promptly when the inflation component is activated, ensuring the active protection function of the head-mounted alarm device while improving its reliability.

[0070] Please see Figure 2 and Figure 3 In one embodiment, the outer side wall of the reinforcing rib 210 is provided with a slider 240, and the inner side wall of the mounting groove is provided with a guide groove 111. The slider 240 is slidably mounted on the guide groove 111. Both the slider 240 and the guide groove 111 adopt a T-shaped structure.

[0071] In one embodiment, sliders 240 are provided on both sides of the reinforcing rib 210, and guide grooves 111 are provided on both sides of the mounting groove. The sliders 240 are slidably mounted on the guide grooves 111 one by one. Both the sliders 240 and the guide grooves 111 adopt a T-shaped structure to prevent the sliders 240 from falling out of the guide grooves 111. In one embodiment, a limiting plate is provided at the opening of the mounting groove. The limiting plate is used to abut against the sliders 240 to prevent the sliders 240 from falling out of the guide grooves 111 when sliding along them. In another embodiment, sliders 240 can also be provided in the mounting groove, and guide grooves 111 can be provided in the reinforcing rib 210. Of course, in other embodiments, sliders 240 and guide grooves 111 can also be set as L-shaped structures, etc.; or sliders 240 and guide grooves 111 can be omitted, and the outer sidewall of the reinforcing rib 210 and the inner sidewall of the mounting groove can be smoothed. Here, there are no restrictions. Thus, by setting the slider 240 and the guide groove 111, the movement of the reinforcing rib 210 relative to the mounting groove can be guided, making it easier for the reinforcing rib 210 to be accurately reset, thereby improving the ease of use and reliability of the head-mounted alarm device.

[0072] Please see Figure 2 and Figure 3 In one embodiment, the inflation assembly includes an airbag 310 and a micro air pump 320. The airbag 310 is disposed between the reinforcing rib 210 and the mounting groove. The micro air pump 320 is disposed in the housing 100 and electrically connected to the control system. The micro air pump 320 is connected to the air inlet of the airbag 310.

[0073] In one embodiment, one side of the airbag 310 is fixed to the bottom of the mounting groove, and the other side of the airbag 310 abuts against the reinforcing rib 210. The air inlet of the airbag 310 is connected to the air outlet of the micro air pump 320 through a micro air tube. When the micro air pump 320 operates, it can inflate the airbag 310, causing the airbag 310 to expand and push the reinforcing rib 210 to move. In one embodiment, the air outlet of the airbag 310 is connected to the air inlet of another air pump through an air tube. When the air pump operates, it can extract the gas from the airbag 310, causing the airbag 310 to contract, so that the reinforcing rib 210 can be reset. In another embodiment, the air outlet of the airbag 310 can also be directly connected to the external environment through an air tube. One end of the air tube is provided with a removable cover to facilitate communication or isolation between the airbag 310 and the external gas. Here, the method of air extraction of the airbag 310 is not limited. In one embodiment, in the initial state, the airbag 310 is in a semi-inflated state to abut against the reinforcing rib 210, ensuring that in a dangerous situation, the airbag 310 can quickly inflate to push the reinforcing rib 210 out of the mounting groove. The airbag 310 is made of a material with good flexibility, airtightness, and lightweight properties, such as rubber or silicone, etc., without specific limitations.

[0074] Thus, in the initial state, the airbag 310 is in a semi-inflated state. When the control system determines that the head-mounted alarm device is in a dangerous situation based on the signal from the detection unit, the control system controls the second fixing member 222 to be de-energized, causing the second fixing member 222 to separate from the first fixing member 221; at the same time, the control system controls the micro air pump 320 to start to inflate the airbag 310, and the airbag 310 quickly pushes the reinforcing rib 210 to move so that the reinforcing rib 210 protrudes from the mounting groove, thereby achieving active protection.

[0075] The technical solution of this utility model embodiment, by setting an airbag 310, not only provides driving force for the reinforcing rib 210, but also buffers part of the impact, further improving the protective performance of the head-mounted alarm device. Furthermore, the airbag 310 has a simple structure and is lightweight, reducing the weight of the head-mounted alarm device and improving ease of use.

[0076] Please see Figures 3 to 5 In one embodiment, the head-mounted alarm device further includes a protective plate 410, a support sleeve 430, a support rod 420, and an elastic element 440. The protective plate 410 is disposed on the housing 100 and located on top of the micro air pump 320; the support sleeve 430 is disposed on the housing 100 and located on both sides of the protective plate 410; one end of the support rod 420 is connected to the protective plate 410, and the other end of the support rod 420 extends into the support sleeve 430; the elastic element 440 is disposed in the support sleeve 430 and connects the support sleeve 430 and the support rod 420.

[0077] In one embodiment, a mounting position is provided on the rear side of the housing 100 for mounting the miniature air pump 320. A protective plate 410 is positioned above the mounting position and connected to the housing 100. A support sleeve 430 is located below the protective plate 410 and on both sides of the mounting position. A support rod 420 provides support for the protective plate 410 and forms a certain angle with it. In one embodiment, the protective plate 410 is inclined to increase the area protecting the miniature air pump 320. The angle between the support rod 420 and the protective plate 410, as well as the inclination angle of the protective plate 410, are flexibly set according to actual conditions and are not limited here. In one embodiment, one end of an elastic element 440 is fixed to the bottom plate of the support sleeve 430, and the other end of the elastic element 440 is connected to the support rod 420. The elastic element 440 can be a shock absorber or a spring, etc., and is not limited here.

[0078] The technical solution of this utility model embodiment includes a protective plate 410, a support rod 420, an elastic element 440, and a support sleeve 430, with the support sleeve 430 providing support for the support rod 420 and the elastic element 440. When the protective plate 410 is impacted, the impact is transmitted to the elastic element 440 through the support rod 420. The elastic element 440 can mitigate the impact, preventing external forces from damaging the miniature air pump 320, and further improving the protective performance of the head-mounted alarm device.

[0079] Please see Figure 2 and Figure 3 The housing 100 includes an outer shell 110 and an inner liner 120. The mounting groove is provided on the outer surface of the outer shell 110. The inner liner 120 is removably covered on the inner surface of the outer shell 110.

[0080] The outer shell 110 is for direct contact with the external environment, and its outer surface is recessed inward to form a mounting groove. The outer shell 110 is made of high-strength materials such as high-density polyethylene, polycarbonate, or carbon fiber reinforced composite materials; no limitation is placed on this material. The inner liner 120 is for direct contact with the user, and its material can be polyester fiber, polyester, or cotton, which offer good breathability and comfort; no limitation is placed on this material either. In one embodiment, a vibration-damping layer 130 is provided between the outer shell 110 and the inner liner 120. The inner liner 120 covers one side of the vibration-damping layer 130, and the other side of the vibration-damping layer 130 is tightly fitted to the inner surface of the outer shell 110. The vibration-damping layer 130 is detachably connected to the outer shell 110. The vibration damping layer 130 can be made of materials with good vibration damping performance, such as foamed metal, silicone, or rubber. There are no limitations on this. In one embodiment, the vibration damping layer 130 has an elastic protrusion 131 on the side facing the outer shell 110, and the inner surface of the outer shell 110 has a groove. The elastic protrusion 131 engages with the groove to achieve a detachable connection. Of course, in other embodiments, the vibration damping layer 130 and the outer shell 110 can also be connected by bonding or screwing. There are no limitations on this. In one embodiment, the acceleration sensor 520 and the position sensor 510 are located between the outer shell 110 and the vibration damping layer 130, and are positioned close to the outer shell 110. The outer shell 110 and the vibration damping layer 130 are correspondingly located in grooves to provide mounting positions. Thus, by providing the outer shell 110, passive protection is provided. The outer shell 110 and the reinforcing rib 210 work together to improve the protective performance of the head-mounted alarm device. By providing the vibration damping layer 130, the impact on the outer shell 110 can be further reduced, improving the safety of the head-mounted alarm device.

[0081] Please see Figure 3 and Figure 4 In one embodiment, the alarm unit includes an audible and visual alarm and a vibration alarm 620. The audible and visual alarm is located in the housing 110 and includes a horn 611 and an indicator light 612. The vibration alarm 620 is located between the inner liner 120 and the housing 110.

[0082] Both the horn 611 and the indicator light 612 are electrically connected to the control system. The horn 611 is used for sound alerts, and the indicator light 612 is used for light alerts. In one embodiment, the periphery of the housing 110 has a protruding outer edge 140, and the horn 611 is located below the outer edge 140 so that the user can clearly receive the sound alerts. The indicator light 612 is located on the outer surface of the housing 110 to alert surrounding personnel. Please refer to [link / reference]. Figure 1In one embodiment, multiple indicator lights 612 are provided, arranged around the housing 110. Of course, in other embodiments, only one indicator light 612 may be provided; this is not a limitation. In one embodiment, a vibration alarm 620 is electrically connected to the control system and is located on the front side of the housing 100 to alert the user through vibration. Specifically, in one embodiment, the vibration alarm 620 is located between the damping layer 130 and the housing 110, close to the inner lining 120, to reduce the impact of the damping layer 130 on the vibration alarm 620. Of course, in other embodiments, only an audible and visual alarm or a vibration alarm 620 may be provided; this is not a limitation.

[0083] When the control system determines that the head-mounted alarm device is in a dangerous situation based on the signal from the detection unit, the control system will activate the audible and visual alarm and illuminate the lights, while simultaneously controlling the vibration alarm 620 to vibrate, thereby alerting the user and surrounding personnel. In this way, by simultaneously setting up the audible and visual alarm and the vibration alarm 620, multiple methods of alerting are achieved, ensuring that the user and surrounding personnel can promptly detect danger, significantly improving the alarm effect and safety of the head-mounted alarm device.
