Description

Technical Field

[0001] This application relates to the field of safety protection equipment technology, and in particular to a split-type smart safety helmet. Background Technology

[0002] In high-risk work environments such as construction, safety helmets are crucial protective equipment for ensuring the head safety of workers. With the development of intelligent technology, smart safety helmets are gradually being adopted. These helmets typically integrate positioning, communication, and environmental monitoring functions, enabling real-time monitoring of worker location information, environmental parameters, and instant communication between workers, significantly improving work safety and management efficiency. However, most current smart safety helmets adopt an integrated design, where the intelligent functional module is fixedly connected to the helmet body and cannot be separated. This integrated structure has significant drawbacks in practical use: when the intelligent functional module malfunctions and needs repair or replacement, the entire helmet must be sent to the repair location, preventing workers from using the helmet for head protection during repairs, causing significant inconvenience, and potentially forcing work to be suspended due to a lack of helmets, thus affecting construction progress. Furthermore, for scenarios where only basic helmet protection is needed, the intelligent module in the integrated smart safety helmet remains idle for extended periods, not only wasting resources but also increasing the helmet's weight and affecting wearing comfort. Furthermore, different work scenarios may have different requirements for intelligent functions. The integrated design of the smart safety helmet cannot flexibly replace the smart modules with different functions according to actual needs, resulting in poor versatility.

[0003] To address this issue, a split-type smart safety helmet has been invented to solve the problems mentioned in the background technology. Utility Model Content

[0004] The purpose of this invention is to overcome the problems of inconvenient maintenance and replacement, waste of resources, and poor versatility caused by the integrated design of existing smart safety helmets. It provides a split-type smart safety helmet, which uses a detachable connection structure between the helmet body and the smart terminal module to achieve flexible installation and disassembly of the smart terminal module, facilitate maintenance and replacement, and improve resource utilization and versatility.

[0005] This application provides a split-type smart safety helmet, which adopts the following technical solution: it includes a safety helmet body and a smart terminal module. The safety helmet body is provided with an installation structure, and the smart terminal module is detachably installed on the safety helmet body through the installation structure.

[0006] Optionally, the installation structure includes a slot, a guide rail, and an elastic locking component on the helmet body, as well as a block and a slider on the smart terminal module. The block can be engaged in the slot, the slider can slide along the guide rail, and the elastic locking component is used to lock the smart terminal module after it is installed in place.

[0007] Optionally, the elastic locking assembly includes a spring and a locking pin disposed on the locking block. The locking slot has a locking hole that matches the locking pin. When the locking block is fully engaged in the locking slot, the locking pin is inserted into the locking hole under the action of the spring to achieve locking. The mounting structure also includes an unlocking button and a connecting rod. The unlocking button is connected to the locking pin through the connecting rod. Pressing the unlocking button can drive the locking pin out of the locking hole to achieve unlocking. The connecting rod is disposed at one end of the unlocking button, and a return spring is disposed between the connecting rod and the locking slot.

[0008] Optionally, the smart terminal module includes a housing and a main control chip, a communication chip, a positioning chip, a power module, and a sensor module disposed within the housing. The sensor module includes an accelerometer, a temperature sensor, and a humidity sensor.

[0009] Optionally, the smart terminal module also includes a display screen and operation buttons mounted on the housing, both of which are electrically connected to the main control chip.

[0010] Optionally, the helmet body is also provided with a charging interface, which is electrically connected to the power module for charging the power module; the smart terminal module and the helmet body are also provided with a contact-type electrical connection structure, including metal contacts on the smart terminal module and corresponding contacts on the helmet body mounting structure. When the smart terminal module is installed in place, the metal contacts contact the corresponding contacts to achieve electrical connection.

[0011] In summary, this application includes the following beneficial technical effects:

[0012] 1. It adopts a split design, with the smart terminal module and the safety helmet body being detachably connected. When the smart terminal module malfunctions, it can be removed separately for repair or replacement without affecting the normal use of the safety helmet body, ensuring that the worker's head protection is not affected and avoiding work interruption due to maintenance.

[0013] 2. In scenarios where smart functions are not required, the smart terminal module can be detached to reduce the weight of the helmet, improve wearing comfort, reduce unnecessary wear and tear on the smart module, extend its service life, and avoid resource waste.

[0014] 3. It can flexibly replace smart terminal modules with different functions according to different work requirements, which improves the versatility and applicability of safety helmets and reduces operating costs.

[0015] 4. The installation structure is reasonably designed. It enables the quick installation and secure locking of the smart terminal module through the card slot, guide rail and elastic locking component. The unlocking operation is simple and convenient, which is convenient for actual use.

[0016] 5. The contact-type electrical connection structure automatically establishes an electrical connection after installation, ensuring the stability and reliability of power and signal transmission between the smart terminal module and the safety helmet body. Attached Figure Description

[0028] Reference Figure 1 , Figure 2 One embodiment shown is: a split smart safety helmet includes a safety helmet body 1 and a smart terminal module 2. In this embodiment, an installation structure 3 is constructed on the outer surface of the safety helmet body 1. The installation structure 3 is located at the front of the safety helmet body 1. The smart terminal module 2 is detachably assembled with the safety helmet body 1 through the installation structure 3.

[0029] The implementation principle of the above embodiment is as follows: the mounting structure 3 provides an assembly base for the smart terminal module 2. Through this structure, the smart terminal module 2 can be stably installed on the safety helmet body 1, and can be easily removed from the safety helmet body 1 when needed. This ensures the stability of the smart terminal module 2 during use and also realizes the flexible separation of the two, meeting the usage needs in different scenarios.

[0030] Reference Figure 5 , Figure 8 , Figure 9 One embodiment shown is as follows: The mounting structure 3 includes a slot 4, a guide rail 5, an elastic locking component 6, a locking block 7, and a slider 8. In this embodiment, the slot 4 is opened on one side of the mounting structure 3 of the helmet body 1. The guide rail 5 is arranged parallel to both sides of the slot 4, and the extension direction of the guide rail 5 is consistent with the direction of the slot 4. The elastic locking component 6 is connected to the end of the slot 4 away from the opening. The locking block 7 is integrally formed on the side of the smart terminal module 2 near the helmet body 1 and corresponds to the position of the slot 4. The slider 8 is integrally formed on both ends of the side of the smart terminal module 2 near the helmet body 1 and corresponds to the positions of the guide rails 5 on both sides respectively. The locking block 7 can be inserted into the slot 4, and the slider 8 can slide along the guide rail 5. The elastic locking component 6 is used to lock the smart terminal module 2 after it is installed in place.

[0031] The implementation principle of the above embodiment is as follows: During installation, the locking block 7 is aligned with the slot 4, and the slider 8 is aligned with the guide rail 5. The smart terminal module 2 is pushed, and the slider 8 slides along the guide rail 5, which guides the movement of the smart terminal module 2 and prevents it from deviating. At the same time, the locking block 7 gradually engages in the slot 4, providing initial positioning for the installation of the smart terminal module 2. After the smart terminal module 2 is installed in place, the elastic locking component 6 plays a role in locking it, ensuring the stability of the smart terminal module 2 after installation and preventing loosening or falling off during use.

[0032] Reference Figure 5 , Figure 9 One embodiment shown is as follows: The elastic locking assembly 6 includes a spring 9, a locking pin 10, a locking hole 11, an unlocking button 12, a connecting rod 13, and a return spring 14. In this embodiment, the end of the locking block 7 away from the smart terminal module 2 has a mounting hole. One end of the spring 9 is connected to the inside of the mounting hole, and the other end of the spring 9 is connected to one end of the locking pin 10. The other end of the locking pin 10 extends out of the mounting hole. The locking pin 10 is set as a wedge-shaped block, and the locking hole 11 is opened on the inner wall of the slot 4 and corresponds to the position of the locking pin 10. The unlocking button 12 is set on the helmet body 1. On the side near the opening of the slot 4, one end of the connecting rod 13 is fixedly connected to the unlock button 12, and the other end of the connecting rod 13 extends to the locking pin 10 and contacts the locking pin 10. The reset spring 14 is sleeved on the connecting rod 13, and one end of the reset spring 14 is connected to the outer wall of the slot 4, and the other end of the reset spring 14 is fixedly connected to the side of the connecting rod 13 near the unlock button 12. When the block 7 is fully inserted into the slot 4, the locking pin 10 is inserted into the lock hole 11 under the action of the spring 9 to achieve locking. Pressing the unlock button 12 can drive the locking pin 10 out of the lock hole 11 to achieve unlocking.

[0033] The implementation principle of the above embodiment is as follows: When the card block 7 is fully inserted into the card slot 4, the spring 9 is in a naturally extended state, pushing the locking pin 10 into the lock hole 11. The locking pin 10 and the lock hole 11 are used to lock the smart terminal module 2, ensuring that it will not fall off accidentally during use. When unlocking is required, press the unlock button 12. The unlock button 12 drives the connecting rod 13 to move. The connecting rod 13 pushes the locking pin 10 to compress the spring 9 and withdraw it from the lock hole 11. At the same time, the reset spring 14 is compressed. After releasing the unlock button 12, the reset spring 14 returns to its original state, driving the connecting rod 13 and the unlock button 12 to reset. The spring 9 also returns to its original state and pushes the locking pin 10 back to the initial position, realizing convenient switching between locking and unlocking. The operation is simple and efficient.

[0034] Reference Figure 1 , Figure 7One embodiment shown is as follows: The smart terminal module 2 includes a housing 15, a main control chip, a communication chip, a positioning chip, a power module 19, and a sensor module. In this embodiment, the housing 15 has a hollow internal structure. The main control chip is fixedly connected to the middle position inside the housing 15 by screws. The communication chip is electrically connected to the main control chip through wires and is located on one side of the main control chip. The positioning chip is electrically connected to the main control chip through wires and is located on the other side of the main control chip. The power module 19 is fixedly connected to the housing 15 near the bottom position by screws and is electrically connected to the main control chip, the communication chip, and the positioning chip through wires respectively. The sensor module includes an acceleration sensor, a temperature sensor, and a humidity sensor. All three are electrically connected to the main control chip through wires and are fixedly installed inside the housing 15.

[0035] As the core of the intelligent terminal module 2, the main control chip receives analog or digital signals from the sensor modules through its internal central processing unit (CPU). These signals undergo analog-to-digital conversion and are then processed and analyzed internally. For example, it determines whether motion data collected by the accelerometer constitutes a dangerous action and performs threshold comparisons on data from the temperature and humidity sensors. After processing, the main control chip transmits the results to the display screen 16 for display via the corresponding interface. Simultaneously, it receives trigger signals from the operation button 17 and executes corresponding instructions according to a preset program, such as switching display content or starting or stopping data acquisition. Furthermore, the main control chip interacts with the communication chip and positioning chip via a serial communication interface. It packages positioning information and sensor data and sends them to the communication chip, which then transmits them externally. It also receives and processes external instructions from the communication chip, which can be an STM32 series chip. The communication chip connects to the main control chip via a serial communication interface and receives data packets from the main control chip. These data packets contain positioning information, environmental data collected by sensors, and the status information of the operators. The communication chip modulates received digital signals into radio frequency signals suitable for wireless transmission and transmits them through its internal radio frequency transceiver module, enabling communication with a remote monitoring platform or other devices. Simultaneously, the communication chip can receive external radio frequency signals, demodulate them into digital signals, and transmit them to the main control chip, allowing operators to receive instructions from the monitoring platform or information from other operators, thus achieving two-way communication. NB-IoT (Narrowband Internet of Things) chips or LoRa chips can be selected. The positioning chip receives radio signals from GPS and BeiDou satellites via an antenna. These signals contain satellite position information and signal transmission time. The chip's internal processor calculates the current geographical coordinates (longitude, latitude, and altitude) of the smart terminal module 2 based on the received signals from multiple satellites using triangulation principles. The positioning chip transmits the calculated coordinate information to the main control chip in real time via a serial communication interface. After processing this information, the main control chip can display the operator's location or, in conjunction with the communication chip, send the location information to a remote monitoring platform, facilitating management personnel's understanding of the operator's distribution. NEO-M8N series modules can be selected for this purpose.

[0036] Accelerometer: A MEMS (Micro-Electro-Mechanical Systems) type triaxial accelerometer, such as the ADXL345, is selected. This type of sensor is small in size, low in power consumption, and can accurately measure acceleration changes in three axes (X, Y, and Z axes), making it suitable for detecting the movement status of workers. Its operating principle involves an internal micromechanical structure. When the sensor is subjected to acceleration, the mass block displaces, causing changes in physical quantities such as capacitance or resistance. The sensor converts these changes into electrical signals and transmits them to the main control chip. The main control chip determines whether the worker has engaged in dangerous actions such as falls or collisions based on the magnitude and direction of the acceleration. If the acceleration exceeds a preset threshold, an alarm mechanism is triggered. Temperature Sensor: A digital temperature sensor, such as the DS18B20, is selected. This sensor uses a single-bus communication method, is simple to wire, has high measurement accuracy, and can measure temperatures within a range of -55℃ to 125℃, meeting the temperature monitoring requirements of the working environment. Its operating principle utilizes the temperature characteristics of the PN junction in semiconductors. When the temperature changes, the forward voltage drop of the PN junction changes. The internal circuitry of the sensor converts this change into a digital signal, which is transmitted to the main control chip via a single bus. After receiving temperature data, the main control chip compares it with the preset safe temperature range. If the temperature is too high or too low, a warning message is displayed on the screen 16 to remind operators to pay attention to environmental changes. Humidity sensor: The humidity detection component of an integrated temperature and humidity sensor, such as the SHT30, is selected. This sensor features high accuracy and low power consumption, and can measure relative humidity within a range of 0-100% RH, making it suitable for use in humid working environments. Its operating principle is based on capacitive humidity sensing. The humidity-sensitive capacitor inside the sensor changes its capacitance value with changes in ambient humidity. The internal signal processing circuit converts the capacitance change into a digital humidity signal, which is transmitted to the main control chip. The main control chip analyzes the humidity data, and when the humidity exceeds the safe threshold, it promptly displays a warning message on the screen 16 to prevent operators from being affected by prolonged work in high humidity environments.

[0037] The implementation principle of the above embodiment is as follows: the housing 15 provides protection and installation space for the various internal chips and modules. The main control chip, as the core component, is electrically connected to the communication chip, positioning chip, and sensor module through wires, and can receive and process the information transmitted by these components. The power module 19 provides power support to other components through wires to ensure that they can work normally. The acceleration sensor, temperature sensor, and humidity sensor are used to collect acceleration, temperature, and humidity information in the working environment, respectively, and transmit this information to the main control chip for processing to realize the intelligent monitoring function of the working environment.

[0038] Reference Figure 1One embodiment shown is as follows: the smart terminal module 2 further includes a display screen 16 and operation buttons 17. In this embodiment, the display screen 16 is embedded and connected to the side of the housing 15 away from the helmet body 1, and the display screen 16 is electrically connected to the main control chip through wires; there are multiple operation buttons 17, all of which are embedded and connected to the lower part of the side of the housing 15 away from the helmet body 1, and are located below the display screen 16. The operation buttons 17 are electrically connected to the main control chip through wires.

[0039] The implementation principle of the above embodiment is as follows: the display screen 16 is electrically connected to the main control chip, and can receive and display the information transmitted by the main control chip, so that the operator can intuitively understand the relevant data; the operation button 17 is electrically connected to the main control chip, and the operator can send instructions to the main control chip by pressing the operation button 17 to realize the function operation of the intelligent terminal module 2, such as switching the display content, starting or turning off certain functions, etc., making human-computer interaction convenient.

[0040] Reference Figure 4 , Figure 7 , Figure 8 One embodiment is shown as follows: a charging interface 18 is constructed on the helmet body 1, and a contact-type electrical connection structure 20 is provided between the smart terminal module 2 and the helmet body 1. In this embodiment, the charging interface 18 is embedded in the side of the helmet body 1 and is electrically connected to the corresponding contact 22 in the contact-type electrical connection structure 20 through a wire; a metal contact 21 is embedded in the edge of the smart terminal module 2 near the helmet body 1 and is electrically connected to the power module 19 through a wire; the corresponding contact 22 is embedded in the mounting structure 3 of the helmet body 1 at the position corresponding to the metal contact 21; when the smart terminal module 2 is installed in place, the metal contact 21 and the corresponding contact 22 make contact to achieve electrical connection.

[0041] The implementation principle of the above embodiment is as follows: When the smart terminal module 2 is installed in place, the metal contact 21 contacts the corresponding contact 22, so that the charging interface 18 forms an electrical connection circuit with the power module 19 through the corresponding contact 22 and the metal contact 21. At this time, the external power supply can charge the power module 19 through the charging interface 18 to ensure that the power module 19 has sufficient power. The contact-type electrical connection structure 20 automatically realizes electrical connection after the smart terminal module 2 is installed in place, without the need for additional wiring operations, which is convenient to use and at the same time ensures the stability of power transmission.

[0042] The working principle of this device is as follows: During installation, the locking block 7 of the smart terminal module 2 aligns with the slot 4 of the safety helmet body 1, and the slider 8 slides along the guide rail 5. After reaching the desired position, the locking pin 10 of the elastic locking component 6 is inserted into the locking hole 11 under the action of the spring 9 to lock. The metal contact 21 contacts the corresponding contact 22 to achieve electrical connection. The power module 19 provides power, and the main control chip receives data such as acceleration, temperature, and humidity collected by the sensor module. After processing, the data is displayed on the display screen 16, and the operation button 17 can be used for function control. The communication chip transmits data and receives commands, and the positioning chip provides location information. During charging, the external power supply charges the power module 19 through the charging interface 18 and the contact structure. During disassembly, pressing the unlock button 12 causes the connecting rod 13 to drive the locking pin 10 out of the locking hole 11, allowing the smart terminal module 2 to be removed.

[0043] The working principle of this device has been explained through the above embodiments. These embodiments only illustrate several implementation methods of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
