Description

Technical Field

[0001] This application relates to the field of smart wearable devices, specifically to a noise detection add-on module for a smart wearable helmet and the helmet itself. Background Technology

[0002] Smart helmets are industrial safety equipment that integrate communication, positioning, video surveillance, and environmental perception functions, and are widely used in high-risk work environments such as coal mines and ports. By integrating cameras, sensors, and communication modules, they enable personnel positioning, remote command, real-time monitoring, and safety early warning, effectively improving operational efficiency and safety levels.

[0003] However, in order to ensure wearing comfort (such as preventing the helmet from being too heavy or bulky to fit comfortably), current smart helmets cannot integrate too many functions into one helmet, resulting in relatively simple and fixed functions that cannot meet the working conditions corresponding to different scenarios. Utility Model Content

[0038] The following embodiments of this application are only used to illustrate specific implementation methods of this application, and these embodiments should not be construed as limitations on this application. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of this application shall be considered equivalent substitutions and fall within the protection scope of this application.

[0039] Those skilled in the art should understand that, in the disclosure of this application, the terms "first," "second," "third," "fourth," "fifth," etc., are only used to distinguish different structures and do not limit the number of specific structures, connection relationships, etc.; in addition, the orientation or positional relationship indicated by "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," etc., is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this application and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this application.

[0040] In this application, the front, back, left, right, and side views of the smart wearable helmet refer to the front, back, left, right, and side views when a person is correctly wearing the smart wearable helmet.

[0041] This embodiment provides a noise detection add-on module for smart wearable helmets, such as... Figures 1-8 As shown, it includes:

[0042] The housing 100 includes a connecting portion for detachable mounting to the outer side of the smart wearable helmet B, preferably to the left or right side of the smart wearable helmet B; in this embodiment, it is specifically the left side (see [reference]). Figure 8 );

[0043] Motherboard 200, wherein the motherboard 200 is disposed within the housing 100;

[0044] The system includes a microprocessor (not shown), a noise detection sensor 300, and a connection interface 400. The microprocessor and the noise detection sensor 300 are mounted on the motherboard 200, and the noise detection sensor 300 and the connection interface 400 are electrically connected to the microprocessor.

[0045] This application provides a noise detection add-on module A, which includes a housing 100, a motherboard 200 disposed within the housing 100, a microprocessor, a noise detection sensor 300, and a connection interface 400. It can be used in a smart wearable helmet. Specifically, only an external interface B1 needs to be provided in the smart wearable helmet. When the noise detection add-on module is detachably fixed to the smart wearable helmet via a connecting part, the connection interface 400 communicates with the external interface B1. Noise signals can be acquired through the noise detection sensor 300 in the noise detection add-on module A. The microprocessor processes the noise signals and transmits the processed noise signals to the smart wearable helmet B through the connection interface 400 and the external interface B1 connected to the connection interface 400. The processor in the smart wearable helmet B further processes the processed noise signals, or the smart wearable helmet transmits the signals to a central control platform for processing to obtain the final processing result. The final processing result is then fed back through the smart wearable helmet to achieve environmental noise monitoring and feedback (such as alarms).

[0046] As described above, the housing 100 can be detachably mounted on the outer side of the smart wearable helmet B. This allows the noise detection add-on module A to be installed on the smart wearable helmet B to monitor ambient noise when noise monitoring is required to prevent irreversible hearing damage to the operator. When ambient noise monitoring is not required, the module can be removed to reduce the weight of the smart wearable helmet B, or to free up the external interface for connecting other modules for other types of testing. This allows the module to be installed only when ambient noise monitoring for specific working conditions is needed, while ensuring the helmet is comfortable to wear (e.g., not too heavy or bulky), thus increasing the functionality of the smart wearable helmet to suit more scenarios and reducing its cost.

[0047] Preferably, the noise detection add-on module A can be powered through the connection interface 400. That is, the reserved structure B1 and the connection interface 400 are a communication and power supply interface, thereby enabling the noise detection add-on module A to be plug-and-play without needing to consider the power supply of the noise detection add-on module. The specific interface scheme can adopt existing structures, which will not be described in detail here.

[0048] Those skilled in the art will know that other circuit components for electrical signal processing, such as filter circuits, operational amplifiers, and digital-to-analog converters, can also be configured on the motherboard 200 as needed, which will not be described in detail here.

[0049] Regarding the aforementioned smart wearable helmet, it can be any existing smart helmet. Based on the solution provided in this application, those skilled in the art can implement communication and power supply between the existing smart helmet and the aforementioned noise detection add-on module A using existing solutions, which will not be elaborated upon here. It should be noted that the applicant of this application has developed a specific solution for a smart wearable helmet that includes the aforementioned noise detection add-on module, and has filed a separate application for it.

[0050] Regarding the type of noise detection sensor used in this application, it is specifically an electret microphone.

[0051] In one embodiment, such as Figures 1-8 As shown, the housing 100 includes a housing body 110, a protrusion 120 formed on the outer side of the housing body 110, and an extension 130 formed on the inner side of the protrusion 120. A receiving cavity 140 is formed on the inner side of the extension 130, and the inner wall of the receiving cavity 140 matches the outer wall of the noise detection sensor 300. Furthermore, a pickup hole 150 is formed on the upper part of the protrusion 120.

[0052] With the structure described above in this embodiment, it is possible to ensure that external environmental noise enters the noise detection external module through the pickup hole 150 and is directly received by the noise detection sensor 300, thereby reducing the adverse effects of vibration caused by noise entering the cavity of the housing 100 on the detection of the noise detection sensor 300 and improving the accuracy of detection.

[0053] Preferably, a waterproof and breathable membrane is provided at the location where the pickup hole 150 is formed on the protrusion. This prevents moisture, dust, etc., from entering the noise detection add-on module and affecting its operational stability and lifespan without significantly affecting the noise detection sensor's reception of ambient noise. Specifically, the waterproof and breathable membrane can be located on the inner side of the protrusion 120. Regarding the material of the waterproof and breathable membrane, existing waterproof and breathable membrane materials can be used, such as ePTFE (expanded polytetrafluoroethylene).

[0054] In one embodiment, such as Figure 3 As shown, the housing body 110 includes a first housing 111 and a second housing 112 arranged vertically; the main board 200 is sandwiched between the first housing 111 and the second housing 112.

[0055] Regarding the connection between the first housing 111 and the second housing 112, a connecting screw 600 can be used. Any commonly used screw can be used.

[0056] In this embodiment, the second housing 112 is the housing closer to the smart wearable helmet B, and the first housing 111 is the housing farther away from the smart wearable helmet B. The aforementioned protrusion 120, extension 130, and microphone hole 150 are provided on the first housing 111.

[0057] Preferably, a sealing strip 700 is provided between the first housing 111 and the second housing 112, thereby further ensuring the stability and service life of the noise detection add-on module.

[0058] In one embodiment, such as Figures 1-8 As shown, the connecting part is a connection point located at the lower part of the first housing 111. The noise detection external module can be detachably connected to the smart wearable helmet through the connection point. The connection interface 400 is located downward at the lower part of the external housing (to facilitate the external module to be inserted downward into the smart wearable helmet).

[0059] Specifically, in this embodiment, the connection points are lugs 113 located at the front and rear of the first housing 111; the noise detection external module also includes a hand-tightening screw 500, the threaded portion of which is adapted to pass through the connection through hole 114 of the lug. Thus, the noise detection external module can be detachably installed on the shell of the smart wearable helmet using the hand-tightening screw 500 and the lugs 113, facilitating the installation and replacement of the external module by personnel.

[0060] The "hanging lug" is an existing design, which includes a protruding portion extending from the housing and a connecting through hole 114 provided in the protruding portion. Multiple "hanging lugs" are generally provided to facilitate stable installation and fixation. The "hand-tightening screw" is an existing design, which includes a threaded portion and a hand-tightening part provided on one side of the threaded portion. The hand-tightening part is cylindrical or other shapes with a large outer diameter to facilitate direct hand-tightening of the screw.

[0061] Regarding the 400 connection interface, such as Figure 5 , Figure 7 As shown, in this embodiment, the connection interface 400 is a female connector, and the corresponding external interface B1 is a pin header, which facilitates sealing between the two and prevents moisture accumulation, thereby ensuring the stability of communication and power supply between the noise detection add-on module and the smart wearable helmet.

[0062] In one embodiment, such as Figure 2As shown, the housing body (specifically the second housing 112 in this embodiment) has an arc surface that matches the outer side of the smart wearable helmet. This allows the noise detection add-on module to be more closely fitted onto the smart wearable helmet, reducing the outer contour of the smart wearable helmet after the noise detection add-on module is installed, and minimizing the impact on the wearer.

[0063] In addition, the noise detection add-on module of this application may also include output components (such as indicator lights / speakers (buzzers)) set on the motherboard to confirm whether the noise detection add-on module of this application has been correctly connected to the smart wearable helmet.

[0064] Based on the above solutions, those skilled in the art will know that this application can also provide an intelligent wearable helmet, which includes the aforementioned noise detection add-on module.

[0065] Although the embodiments of this application have been described above, this application is not limited to the specific embodiments and application fields described above. The specific embodiments described above are merely illustrative and instructive, and not restrictive. Those skilled in the art, based on the guidance of this specification and without departing from the scope of protection of the claims of this application, can make many other forms, all of which are within the scope of protection claimed in this application.
