A smart safety helmet

Abstract

This utility model discloses a smart safety helmet, which includes a smart module and a protective helmet body. The smart module includes a shell and functional devices disposed within the shell. The protective helmet body has a connecting part, and the shell of the smart module and the connecting part of the protective helmet body are detachably connected. Based on the physical separation design of the smart module and the protective helmet body, this design breaks through the mandatory constraints of traditional integrated structures on equipment replacement strategies. When the protective helmet body reaches the scrap standard due to material aging or mechanical damage, the operator can separately remove the smart module and assemble it into a new protective helmet body for continued service.

Description

Technical Field

[0001] This utility model relates to the field of protective equipment technology, and in particular to an intelligent safety helmet. Background Technology

[0002] In the field of industrial safety equipment, smart safety helmets have significantly improved operational safety management efficiency by integrating functional modules such as environmental sensing and data interaction. However, the structural defects of existing products severely restrict their practical application value, most notably the contradiction between functional expandability and equipment sustainability.

[0003] Traditional smart safety helmets generally employ an integrated, fixed connection design between the smart module and the protective helmet body. This rigid architecture prevents the physical separation of core functional modules (including sensors, processors, and communication units). This design flaw essentially transforms the safety helmet into a closed system with fixed functions, making the hardware configuration unable to respond to dynamic and diverse field requirements. More seriously, due to factors such as UV aging and mechanical impact, the mandatory replacement cycle of the protective helmet body differs significantly from the effective lifespan of the electronic modules. When the protective helmet body reaches its end-of-life, the smart module, still functioning normally, is forced to be discarded along with the entire device. This not only causes unnecessary waste of electronic component resources but also creates cost pressure from repeated procurement. Utility Model Content

[0004] The technical problem to be solved by this utility model embodiment is that the existing smart safety helmets have an integrated design of the smart module and the protective helmet body, which requires the whole helmet to be replaced when needed, resulting in high replacement costs.

[0005] To address the aforementioned problems, this utility model provides an intelligent safety helmet, which includes an intelligent module and a protective helmet body. The intelligent module includes a housing and functional devices disposed within the housing. The protective helmet body has a connecting portion, and the housing of the intelligent module and the connecting portion of the protective helmet body are detachably connected.

[0006] A further technical solution is that the side of the housing is provided with a slot, and the connecting part includes the brim of the protective cap and a snap-fit ​​block protruding from the brim. The slot and the snap-fit ​​block are detachably snap-fitted together.

[0007] A further technical solution is that the functional device includes a processor, a storage unit, and a sensor, and the storage unit and the sensor are both connected to the processor.

[0008] A further technical solution is that the housing is provided with a power supply interface and a communication interface, the power supply interface being connected to the processor, and the communication interface being connected to the processor.

[0009] A further technical solution is that the smart safety helmet also includes a camera, which is rotatably connected to the shell.

[0010] A further technical solution is that the camera includes a damping shaft, the housing has a shaft hole, and the damping shaft is interference-fitted with the shaft hole.

[0011] A further technical solution is that the damping shaft includes a shaft body and a bushing fixedly sleeved on the shaft body; a limiting groove is formed on the outer side of the bushing, and a limiting post is provided on the housing. The limiting post is located on one side of the limiting groove, and the limiting post limits the rotation angle of the damping shaft by limiting the limiting groove.

[0012] A further technical solution is that the shaft body has a wire-passing hole arranged along the axial direction.

[0013] A further technical solution is that the smart safety helmet also includes a battery module, which is detachably connected to the protective helmet body; the battery module is connected to the smart module to provide power to the smart module.

[0014] A further technical solution is that the smart safety helmet also includes a power indicator light, and the smart module includes a battery management system, which is connected to the battery module and the power indicator light.

[0015] Compared with the prior art, the technical effects achieved by the embodiments of this utility model include:

[0016] This utility model embodiment proposes an intelligent safety helmet, including an intelligent module and a protective helmet body. The intelligent module includes a shell and functional devices disposed within the shell. The protective helmet body has a connecting part, and the shell of the intelligent module and the connecting part of the protective helmet body are detachably connected. The intelligent module and the protective helmet body of this intelligent safety helmet can be physically separated, so that if the protective helmet body is damaged, only the protective helmet body can be replaced, and the intelligent module can continue to be used, thereby avoiding resource waste, reducing replacement costs, and allowing the use of different types of intelligent modules to adapt to different usage needs.

[0017] Based on the physical separation design of the intelligent module and the protective cap, this approach breaks through the mandatory constraints of traditional integrated structures on equipment replacement strategies. When the protective cap reaches the scrap standard due to material aging or mechanical damage, the operator can separately remove the intelligent module and assemble it into a new protective cap for continued service. This technical approach completely eliminates the resource mismatch phenomenon of discarding fully functional electronic components along with the entire housing, significantly reducing the overall operating cost throughout the equipment's life cycle.

Detailed Implementation

[0028] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Similar component reference numerals in the drawings represent similar components. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] It should be understood that, when used in this specification and the appended claims, the terms "comprising" and "including" indicate the presence of the described features, integrals, steps, operations, elements and / or components, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components and / or collections thereof.

[0030] It should also be understood that the terminology used in this specification of embodiments of the present invention is for the purpose of describing particular embodiments only and is not intended to limit the embodiments of the present invention. As used in this specification of embodiments of the present invention and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0031] See Figures 1-5 This utility model provides a smart safety helmet in which the smart module 10 and the protective helmet body 20 can be physically separated. Therefore, if the protective helmet body 20 is damaged, only the protective helmet body 20 needs to be replaced, while the smart module 10 can continue to be used, thus avoiding resource waste and reducing replacement costs. To achieve the above technical objectives, the smart safety helmet includes a smart module 10 and a protective helmet body 20, the specific structure of which is described below:

[0032] The intelligent module 10 includes a housing 11 and functional devices disposed within the housing 11. The intelligent module 10 is an independent module, the housing 11 serves a protective function, and the functional devices are installed inside the housing 11.

[0033] The protective cap 20 is provided with a connecting part 21, and the housing 11 of the smart module 10 is detachably connected to the connecting part 21 of the protective cap 20. For example, the detachable connection can be achieved by fasteners and / or buckles, which is not specifically limited in this utility model.

[0034] Based on the physical separation design of the intelligent module 10 and the protective cap 20, the traditional integrated structure breaks through the mandatory constraints on equipment replacement strategies. When the protective cap 20 reaches the scrap standard due to material aging or mechanical damage, the operator can separately remove the intelligent module 10 and assemble it into a new protective cap 20 for continued service. This technical approach completely eliminates the resource mismatch phenomenon of discarding fully functional electronic components along with the entire housing 11, significantly reducing the overall operating cost throughout the equipment's life cycle.

[0035] This utility model embodiment proposes an intelligent safety helmet, including an intelligent module 10 and a protective helmet body 20. The intelligent module 10 includes a housing 11 and functional devices disposed within the housing 11. The protective helmet body 20 is provided with a connecting part 21. The housing 11 of the intelligent module 10 and the connecting part 21 of the protective helmet body 20 are detachably connected. The intelligent module 10 and the protective helmet body 20 of this intelligent safety helmet can be physically separated. Therefore, if the protective helmet body 20 is damaged, only the protective helmet body 20 can be replaced, and the intelligent module 10 can continue to be used, thereby avoiding resource waste, reducing replacement costs, and allowing different types of intelligent modules 10 to be used to adapt to different usage needs.

[0036] Furthermore, in some preferred embodiments, the side of the housing 11 is provided with a slot 111, and the connecting part 21 includes the brim 211 of the protective cap body 20 and a snap-fit ​​block 212 protruding from the brim 211. The slot 111 and the snap-fit ​​block 212 are detachably snap-fitted together.

[0037] Specifically, by engaging the slot 111 with the engaging block 212, the smart module 10 and the protective cap 20 can be detachably connected. Furthermore, since no fasteners are required, the assembly and disassembly of the smart module 10 and the protective cap 20 are more convenient.

[0038] Furthermore, in some preferred embodiments, the functional device includes a processor 12, a storage unit 13, and a sensor 14, both of which are connected to the processor 12.

[0039] The housing 11 is provided with a power supply interface 15 and a communication interface 16. The power supply interface 15 is connected to the processor 12, and the communication interface 16 is connected to the processor 12.

[0040] Specifically, the appropriate sensor 14 can be selected according to specific usage requirements; this invention does not specifically limit this. The power supply interface 15 can be, for example, a Type-C interface, for connecting to a power source, such as a battery module 40. The communication interface 16 is used to connect to a communication module, such as a Bluetooth module or a Wi-Fi module.

[0041] Furthermore, in some preferred embodiments, the smart helmet also includes a camera 30, which is rotatably connected to the shell 11.

[0042] Specifically, the camera 30 includes a damping shaft 31, and the housing 11 has a shaft hole 112. The damping shaft 31 and the shaft hole 112 are interference-fitted. Thus, under the action of external force, the camera 30 can rotate, and after the external force is removed, the camera 30 stops moving. Through the interference fit between the damping shaft 31 and the shaft hole 112, the camera 30 has an adjustable angle and a self-locking function.

[0043] Furthermore, the damping shaft 31 includes a shaft body 311 and a bushing 312 fixedly sleeved on the shaft body 311; a limiting groove 313 is formed on the outer side of the bushing 312, and a limiting post 113 is provided on the housing 11. The limiting post 113 is located on one side of the limiting groove 313, and the limiting post 113 is embedded in the limiting groove 313 and located within the movement trajectory range of the limiting groove 313. By limiting the limiting groove 313 with the limiting post 113, the rotation angle of the damping shaft 31 is limited.

[0044] Specifically, the bushing 312 can be connected to the shaft body 311 by fasteners, and the bushing 312 and the shaft body 311 are fixed as a whole.

[0045] The limiting groove 313 has a certain length and may be specifically arc-shaped. When the damping shaft 31 rotates, the two side walls of the limiting groove 313 and the limiting post 113 form a limiting position, thereby restricting the rotation of the damping shaft 31. The rotation angle of the damping shaft 31 may be specifically limited to 40°, but this utility model does not specifically limit it.

[0046] Furthermore, the shaft 311 has a cable passage hole 314 arranged along the axial direction. The cable inside the camera 30 can pass through the cable passage hole 314 and connect to the processor 12 of the smart module 10.

[0047] Furthermore, in some preferred embodiments, the smart safety helmet further includes a battery module 40, which is detachably connected to the protective helmet body 20; the battery module 40 is connected to the smart module 10 to supply power to the smart module 10.

[0048] Specifically, the battery module 40 can be detachably connected via fasteners and / or clips, which is not specifically limited in this invention. The battery module 40 is connected to the power supply interface 15 of the smart module 10 via a power cable 60 to supply power to the smart module 10.

[0049] Furthermore, the smart helmet also includes a power indicator light 50, and the smart module 10 includes a battery management system (BMS), which is connected to the battery module 40 and the power indicator light 50.

[0050] Specifically, the power indicator 50 is an LED light strip, which can emit various colors such as green, yellow and red to indicate different battery levels.

[0051] Furthermore, it also includes a display screen, which is connected to the battery management system. The power indicator light 50 and the display screen can be mounted on the surface of the battery module 40.

[0052] The software algorithm in the battery management system is as follows:

[0053] 1. Power Acquisition: Real-time acquisition of battery voltage, current and temperature data through the Battery Management System (BMS) to calculate the remaining power.

[0054] 2. Battery level display: Transmits remaining battery level information to the LED light strip or display screen and updates the display status in real time.

[0055] 3. Low battery warning: When the remaining battery level is below 20%, a voice broadcast or vibration reminder will be triggered to prompt the user to charge the battery in time.

[0056] The algorithm flow is as follows:

[0057] 1. Initialization: When the system starts, the battery management system and the display screen are initialized, and the communication connection between the two is established.

[0058] 2. Data Acquisition: The battery management system collects battery voltage, current and temperature data from battery module 40 every 1 second.

[0059] 3. Power Calculation: Based on the collected data, the remaining power of battery module 40 is calculated using either the coulomb counting method or the voltage mapping method.

[0060] 4. Status Update: Transmit the remaining battery information to the LED light strip or display screen to update the display status.

[0061] 5. Low battery warning: When the remaining battery level is lower than a set threshold (e.g., 20%), a voice broadcast or vibration reminder will be triggered.

[0062] Through the above-mentioned technical means, this utility model achieves the following effects:

[0063] 1. Structural flexibility: The intelligent module 10 is detachable, which extends the service life of the intelligent module 10 and reduces resource waste.

[0064] 2. Ease of operation: The camera is adjustable at a 30-degree angle to meet diverse shooting needs and reduce user head fatigue.

[0065] 3. Safety in use: The intuitive power display function ensures that users can keep track of the equipment's power status at any time, avoiding work interruptions due to insufficient power.

[0066] 4. Intelligent Management: The power management algorithm enables real-time monitoring and early warning of power consumption, improving the safety and reliability of the equipment.

[0067] This invention significantly improves the functionality, flexibility, and user experience of smart safety helmets through hardware structure optimization and software algorithm design, making them suitable for efficient management and operation in complex working environments.
