[0002] In various work scenarios involving safe production, safety helmets are important equipment to protect the lives of workers. Workers must wear safety helmets correctly when working to reduce head injuries caused by accidents such as falling objects from heights and collisions.

[0003] However, in practice, some workers, due to a lack of safety awareness, often fail to fasten their chin straps or even enter the work area without wearing a safety helmet. Some workers also fail to notice or adjust their helmets in time due to prolonged work. This failure to wear safety helmets as required increases the risk of head injuries to workers in the event of an accident. Once an accident occurs, it may cause serious head injuries to workers, resulting in huge losses to individuals, families, and companies.

[0004] Therefore, a pressure-type helmet-wearing reminder device is needed to monitor the helmet-wearing status, promptly remind workers to wear them correctly, and ensure their safety. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a pressure-type safety helmet wearing reminder device to solve the technical problem in the prior art where workers do not wear safety helmets correctly as required or due to negligence.

[0006] The purpose and function of this utility model's pressure-type safety helmet wearing reminder device are achieved through the following specific technical means:

[0007] A pressure-type safety helmet wearing reminder device includes a housing installed inside the chin rest of the safety helmet. The housing includes a mounting plate and a top plate, with the housing mounted on the top of the mounting plate. The mounting plate is equipped with a push-button switch and a buzzer for detecting and reminding workers whether they are wearing the safety helmet correctly. A button battery for powering the device is located inside the mounting plate, and a control module is located at the bottom of the mounting plate. A silicone pad for dispersing chin pressure is installed on the top plate, and a main switch for controlling the overall circuit connection of the device is installed on one side of the housing.

[0014] According to a preferred embodiment, the silicone pad is mounted on the top plate by an adhesive layer, and a groove is provided at the bottom of the silicone pad, with the top of the push switch fitted inside the groove.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. This utility model monitors the wearing status of safety helmets through a push-button switch and a control module. When the worker wears the safety helmet correctly, the chin strap applies normal pressure to the push-button switch, and the control module determines that it is correctly worn; otherwise, a buzzer is triggered to issue a loud reminder. This reminder mechanism allows workers to immediately realize and correct any wearing problems, reducing safety risks caused by improper helmet wearing and improving the safety protection of workers' heads. Simultaneously, the control module can send wearing data to a computer, allowing managers to monitor employee wearing status. This helps managers promptly identify and address improper wearing behavior, and also allows for data analysis to pinpoint weaknesses in safety management, enabling targeted measures to improve workplace safety management.

[0017] 2. The inclusion of humidity and temperature sensors enables the device to detect complex working environments. The humidity sensor monitors the amount of sweat seeping into the device, preventing damage to internal circuitry due to moisture, extending the device's lifespan, and adapting to different working conditions. The temperature sensor detects the ambient temperature and promptly alerts workers to prevent heatstroke in high-temperature situations. Furthermore, a power indicator light clearly displays the button battery level; a solid green light indicates sufficient power, while a color change or flashing indicator suggests charging when the battery is low. This prevents the alert function from malfunctioning due to battery issues, ensuring stable device operation, providing continuous and reliable safety for workers, and comprehensively optimizing the user experience.

[0025] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model.

[0026] Example:

[0027] like Figures 1 to 5 As shown, a pressure-type helmet wearing reminder device includes a housing, which is installed inside the chin rest 28 of the helmet. The housing includes a mounting plate 11 and a top plate 12. The housing 13 is mounted on the top of the mounting plate 11, and the top plate 12 is mounted on the top of the housing 13.

[0028] Specifically, the overall framework of the device was constructed, improving its structural stability and protection.

[0029] like Figure 3 As shown, the mounting plate 11 is equipped with a push-button switch 14 and a buzzer 15 for detecting and reminding workers whether they are wearing safety helmets correctly.

[0030] Specifically, the control module 17 is electrically connected to the push-button switch 14. When the worker wears the safety helmet correctly, the chin strap applies pressure to the silicone pad 18 on the top plate 12, thereby triggering the push-button switch 14 located in the groove at the bottom of the silicone pad 18. The push-button switch 14 transmits a signal to the control module 17, informing the worker that the safety helmet is worn correctly. The control module 17 is also electrically connected to the buzzer 15. If the push-button switch 14 is not triggered, indicating that the safety helmet is not worn correctly, the control module 17 receives this signal and controls the buzzer 15 to emit a sound, which is transmitted through multiple sound holes at one end of the outer casing 13, reminding the worker to wear the safety helmet correctly. In addition, when the humidity sensor 21 detects that the humidity inside the device exceeds the range, or the temperature sensor 24 detects that the ambient air temperature reaches the high temperature threshold, the control module 17 will also control the buzzer 15 to emit sounds of different frequencies as corresponding reminders. This achieves the detection and reminder function of the safety helmet wearing status, improving the practicality of the device in ensuring the safety of workers. When the worker is wearing a safety helmet correctly, the press switch 14 is triggered. If the helmet is not worn correctly, the buzzer 15 will sound an alarm to remind the worker, especially on construction sites, to wear the helmet properly and reduce safety risks. The press switch 14 can be a TS-A007 type press switch, and the buzzer 15 can be a TMB12A05 integrated active electromagnetic buzzer.

[0031] The mounting plate 11 contains a button battery 16 for powering the device.

[0032] Specifically, the button battery 16 powers the entire device and is electrically connected to the control module 17, providing stable power to the control module 17 and other electrical components. This ensures the control module 17 operates normally and executes various control commands. This achieves self-powered operation, enhancing the device's independence and portability. The button battery 16 is small and can continuously provide stable power, eliminating the need for complex external power lines. It can be used in various work scenarios, such as power line inspection and outdoor construction. The button battery 16 can be a LI R1620 lithium-ion button battery.

[0033] The bottom of the mounting plate 11 is equipped with a control module 17. A silicone pad 18 for dispersing chin pressure is installed on the top plate 12, and a main switch 19 for controlling the connection of the main equipment circuit is installed on one side of the housing 13.

[0034] Specifically, a control module 17 is installed at the bottom of the mounting plate 11 for overall device operation control; a silicone pad 18 is installed on the top plate 12 to distribute chin pressure and improve user comfort; a master switch 19 is installed on one side of the outer shell 13 to control the overall device circuit, achieving centralized control of the device and improving its functionality and user experience. For example, when wearing a safety helmet for extended periods, the silicone pad 18 reduces chin pressure, and the master switch 19 allows workers to easily turn the device on or off as needed. The control module 17 can use an nRF52832 chip.

[0035] One end of the mounting plate 11 is equipped with a humidity sensor 21 for detecting whether sweat has seeped into the casing and a charging interface 22 for charging the device.

[0036] Specifically, the control module 17 is electrically connected to the humidity sensor 21 at one end of the mounting plate 11. The humidity sensor 21 monitors whether sweat has seeped into the housing. When the humidity exceeds the normal range, it transmits a signal to the control module 17. The control module 17 then responds by controlling the buzzer 15 to emit a sound at a specific frequency, reminding employees or managers that the device may be damp and needs to be dealt with promptly. This achieves the functions of monitoring the internal environment of the housing and facilitating charging, improving the adaptability and maintainability of the device. The humidity sensor 21 can detect sweat seepage in a timely manner, reminding operators to clean or replace the device to prevent corrosion of components due to sweat; the charging interface 22 facilitates timely replenishment of power, ensuring continuous normal operation of the device. The humidity sensor 21 can be an HM1500 type humidity sensor.

[0037] The mounting plate 11 has a slot at the top, and a battery slot is located at the bottom of the slot. A button battery 16 is installed in the battery slot, and a card plate 29 is provided above the button battery 16. The card plate 29 is secured in the slot.

[0038] Specifically, the installation and circuit connection of the button battery 16 were achieved, improving the stability and reliability of the device's power supply system. This ensures that the button battery 16 will not shake or shift during device use, and the card plate is electrically connected to the button battery, guaranteeing stable circuit connectivity and continuous stable power supply even in bumpy working environments.

[0039] The mounting plate 11 has a mounting groove at its bottom, and a waterproof baffle 23 is provided below the mounting plate 11. The waterproof baffle 23 is engaged with the opening of the mounting groove to form a mounting cavity, and the control module is installed in the mounting cavity. The waterproof baffle 23 is installed on the mounting groove, and a detection hole is provided on the waterproof baffle 23. A temperature sensor 24 for detecting air temperature is provided in the detection hole.

[0040] Specifically, the temperature sensor 24 inside the detection hole of the waterproof baffle 23 at the bottom of the mounting plate 11 is electrically connected to the control module 17. The temperature sensor 24 detects the ambient air temperature. When the temperature reaches or exceeds a preset high-temperature threshold, it transmits a signal to the control module 17. The control module 17 then controls the buzzer 15 to emit sounds of different frequencies to remind employees to take precautions against heatstroke. This achieves both waterproofing and temperature detection functions, improving the safety and functionality of the device in complex environments. The waterproof baffle 23 prevents water ingress from damaging components, and the temperature sensor 24 monitors the ambient temperature, promptly alerting workers to prevent heatstroke in high-temperature environments, thus protecting their health. The temperature sensor 24 can be an LM35 type temperature sensor.

[0041] The housing 13 has a mounting hole on one side, and the main switch 19 is installed in the mounting hole. One end of the housing 13 has multiple sound holes for sound transmission, and the other end has a light slot, in which a power indicator light 26 is installed to remind the user whether the battery is sufficient.

[0042] Specifically, the control module 17 is electrically connected to the main switch 19 inside the mounting hole on one side of the housing 13. At the same time, the control module 17 is equipped with a wireless module, which connects to an external computer. Thus, when the manager starts work, he / she turns on the main switch 19 with a special key, the control module 17 is powered on and starts working, and automatically transmits the clock-in information to complete the clock-in process; when the manager leaves work, he / she turns off the main switch 19, the control module 17 transmits the clock-out information, and stops the operation of related functions.

[0043] The control module 17 is electrically connected to the power indicator light 26 in the light slot at the other end of the housing 13. The control module 17 acquires the device's power information and, by controlling the on / off state or different display states of the power indicator light 26, intuitively displays to the user whether the power is sufficient, allowing operators or managers to understand the device's power status in a timely manner and prepare for charging in advance. The installation of the main switch 19 facilitates operation by operators and improves the ease of use of the device. Multiple sound holes are provided at one end of the housing 13 to provide a channel for the transmission of the buzzer 15's sound, ensuring that the reminder sound can reach the operators and enhancing the reminder effect. The light slot at the other end houses the power indicator light 26, which intuitively displays to the user whether the power is sufficient, allowing operators to understand the device's power status in a timely manner and prepare for charging in advance, improving the device's functionality and practicality. For example, in a noisy construction site, the sound holes ensure the buzzer 15's sound can be heard, while the power indicator light 26 allows operators to know the power level at any time, avoiding the device's normal operation due to insufficient power.

[0044] Both ends of the outer shell 13 are fitted with foam pads 27 for securing the outer shell to the chin rest 28 and increasing wearing comfort.

[0045] Specifically, a convenient connection is achieved between the outer shell and the helmet chin rest 28. The soft foam material increases wearing comfort and enhances the user experience. The adhesive strength of the foam pad 27 ensures the device remains stably fixed to the chin rest 28 during wear, preventing easy shifting or falling off. Its softness also reduces pressure on the contact area between the chin and the device, providing a more comfortable wearing experience, especially during extended work hours.

[0046] The top plate 12 has a through hole and a charging hole. The push switch 14 passes through the through hole, and the charging hole is located above the charging interface 22. A plug 25 is installed in the charging hole to prevent sweat from seeping in.

[0047] Specifically, a through hole is provided on the top plate 12 to allow the push-button switch 14 to pass through, ensuring that the push-button switch 14 can properly sense the wearing status of the safety helmet, while also providing reasonable space for its installation, thus improving the rationality of the device structure. The charging port is located above the charging interface 22, and a plug 25 is installed in the charging port. On the one hand, this facilitates the connection of charging equipment to charge the device; on the other hand, the plug 25 prevents sweat from seeping into the device through the charging port and damaging the internal circuitry, thereby improving the device's waterproof performance and durability.

[0048] The silicone pad 18 is installed on the top plate 12 through an adhesive layer. The bottom of the silicone pad 18 has a groove, and the top of the push switch 14 is fitted into the groove.

[0049] Specifically, the system achieves the proper coordination between the silicone pad 18 and the push-button switch 14, as well as the installation of the silicone pad 18 on the top plate 12. This connection method ensures that the push-button switch 14 functions normally, while the silicone pad 18, while distributing chin pressure, does not interfere with the push-button switch 14's detection of the helmet wearing status, thus improving the overall coordination and functionality of the device. For example, during the process of workers wearing safety helmets, the silicone pad 18, while providing pressure relief, does not hinder the push-button switch 14's detection, ensuring the normal operation of the reminder function.

[0050] The specific usage and function of this embodiment are as follows:

[0051] Before use, first tear off the seals on the foam pads 27 at both ends of the outer shell 13, then align the device with the middle position of the chin rest 28 of the safety helmet and press to stick it on to complete the installation. When starting work, the manager uses a special key to open the main switch 19 in the mounting hole on one side of the outer shell 13, so that the control module 17 at the bottom of the mounting plate 11 works and automatically transmits the attendance information to complete the attendance check-in. When employees wear safety helmets, if they wear them correctly, the chin strap applies pressure to the silicone pad 18 on the top plate 12 to trigger the press switch 14. If they do not wear them correctly, the buzzer 15 sounds and is transmitted through multiple sound holes at one end of the outer shell 13 to remind them to wear them correctly. During operation, the humidity sensor 21 at one end of the mounting plate 11 monitors the humidity inside the device. When the humidity exceeds the range, it sends a signal to the control module 17, which controls the buzzer 15 to sound a specific frequency to remind them to handle the situation. At the same time, the temperature sensor 24 in the detection hole of the waterproof baffle 23 at the bottom of the mounting plate 11 detects the ambient air temperature. When the temperature reaches the high temperature threshold, the control module 17 controls the buzzer 15 to sound different frequencies to remind them to take precautions against heatstroke. At the end of the workday, the manager uses a special key to turn off the main switch 19 inside the mounting hole on one side of the casing 13. The control module 17 transmits information to complete the clock-out process. At the same time, the manager observes the power indicator light 26 inside the light slot at the other end of the casing 13 to determine the power level. If the power is insufficient, the manager arranges for charging.

[0052] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments.
