Description

Technical Field

[0001] This application relates to the field of smart wearable devices, specifically to an external module for a smart wearable helmet and the helmet itself. Background Technology

[0002] Smart helmets are high-tech equipment integrating the Internet of Things, artificial intelligence, and wearable technology, and are widely used in the safety management and efficient operation of port workers. Through built-in cameras, sensors, and communication modules, smart helmets can monitor environmental data, operational status, and personnel location in real time, assisting managers in remote command and risk warning. They not only improve operational efficiency but also significantly reduce the incidence of safety accidents, driving the intelligent and digital transformation of port operations.

[0003] Port operations often involve high temperatures and humidity, which can easily cause shock to workers. Therefore, accurate temperature and humidity monitoring is crucial for smart helmets. However, integrating all functional modules for all operating conditions into a single helmet would make it too heavy to wear.

[0004] Therefore, current smart helmets, considering factors such as weight and size, have relatively simple and fixed functions; and the temperature and humidity monitoring units in current smart helmets are often located on the upper / lower part of the brim (visor), which can lead to inaccurate temperature and humidity detection. Utility Model Content

[0009] The system includes a microprocessor, a detection sensor, and a connection interface. The microprocessor and the detection sensor are mounted on the motherboard, and the detection sensor and the connection interface are electrically connected to the microprocessor. The detection sensor includes a temperature and humidity sensor.

[0010] Furthermore, the detection sensor also includes a gas detection sensor.

[0011] Furthermore, the gas detection sensor includes a catalytic combustion sensor, a hydrogen sulfide detection sensor, an oxygen detection sensor, and / or a carbon monoxide detection sensor.

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.

Therefore, the above terms should not be construed as limitations on this application.

[0041] This embodiment provides an external module for a smart wearable helmet, such as... Figures 1 to 8 As shown, it includes: a housing 100, the housing 100 including a connecting portion, which allows it to be detachably mounted on the left or right side of the smart wearable helmet;

[0042] Motherboard 200, wherein the motherboard 200 is disposed within the housing 100;

[0043] The system includes a microprocessor (not shown), a detection sensor 300, and a connection interface 400. The microprocessor and the detection sensor 300 are mounted on the motherboard 200, and the detection sensor 300 and the connection interface 400 are electrically connected to the microprocessor. The detection sensor 300 includes a temperature and humidity sensor.

[0044] This application provides an external module A, including a housing 100, a mainboard 200 disposed within the housing 100, a microprocessor, a detection sensor 300 (including a temperature and humidity sensor), and a connection interface 400. It can be used in a smart wearable helmet. Specifically, it only requires an external interface B1 to be provided in the smart wearable helmet. When the external module is detachably fixed to the smart wearable helmet via a connecting part, the connection interface 400 communicates with the external interface B1, enabling the acquisition of detection signals through the detection sensor 300 (including the temperature and humidity sensor) in the external module A. (e.g., detection signals corresponding to temperature and humidity), the microprocessor processes the detection signal and transmits the processed detection signal 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 detection signal or transmits it to the 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 realize the monitoring and feedback (e.g., alarms) of the required detection items (e.g., ambient temperature and humidity).

[0045] As described in the background section, the temperature and humidity monitoring units (such as temperature and humidity sensors) in existing smart helmets are often located on the upper / lower part of the brim (visor). The inventors' research revealed that, in situations such as port operations, when the sensor is located on the upper part of the brim (visor), the temperature detected by the temperature and humidity monitoring unit will be higher than the actual ambient temperature, and the relative humidity will be lower. Conversely, when located on the lower part of the brim (visor), the opposite error occurs. Through extensive on-site research, the inventors found that when the temperature and humidity sensor is located on the outer side of the smart wearable helmet, the temperature and humidity detection results are extremely close to the actual ambient temperature and humidity under normal operating conditions. Furthermore, for typical smart helmets, most functional components are concentrated in the front and rear. The inventors designed the external module of this application to be suitable for installation on the left or right side of the helmet, so as to accurately detect the ambient temperature and humidity without affecting the existing smart helmet's functionality and weight distribution.

[0046] Furthermore, as mentioned above, this application provides a detachable external module. When monitoring ambient temperature and humidity is required in high-temperature and high-humidity environments, the external module A can be installed on the smart wearable helmet B to monitor the ambient temperature and humidity. When monitoring ambient temperature and humidity is not required, the external 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 specific ambient temperature and humidity monitoring is needed, while ensuring the helmet is suitable for wearing (e.g., not too heavy or too bulky), thus increasing the functionality of the smart wearable helmet to suit more scenarios and reducing its cost.

[0047] Preferably, the external module A can be powered through the connection interface 400. That is, the external interface B1 and the connection interface 400 are a communication and power supply interface, thereby enabling the external module A to be plug-and-play without having to consider the power supply of the external module. The specific interface scheme can adopt the existing structure, 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 use existing methods to reserve external interfaces on existing smart helmets and achieve communication and power supply with the aforementioned external module A, which will not be elaborated 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 external module, and has filed a separate application for it.

[0050] In one embodiment, such as Figure 3 As shown, the detection sensor also includes a gas detection sensor.

[0051] Since toxic gases are often present in actual working conditions, such as high temperature and high humidity, this embodiment further integrates a gas detection sensor into the external module to make the external module to be protected by this application suitable for more application scenarios.

[0052] Preferably, the gas detection sensor includes a catalytic combustion sensor, a hydrogen sulfide detection sensor, an oxygen detection sensor, and / or a carbon monoxide detection sensor.

[0053] In one embodiment, such as Figure 3 , Figure 6 As shown, the housing 100 includes a housing body 110 and a plurality of protrusions 120 formed on the outer side of the housing body 110. Each of the protrusions 120 has a receiving cavity 130 formed on its inner side, and the receiving cavity 130 can respectively accommodate each of the detection sensors 300. Each of the protrusions 120 has a plurality of through holes.

[0054] Common gas detection sensors (such as the aforementioned catalytic combustion sensor) often have a slight impact on the surrounding temperature during normal use. However, the external module used in this application for a smart wearable helmet dictates that the module itself cannot be too large, resulting in the sensors within the module being relatively close together. Therefore, this application uses a protrusion 120 to house and isolate each sensor 300 within the receiving cavity 130, thereby reducing mutual interference between the sensors 300. On-site research by the inventors has shown that the protrusion 120 effectively isolates the sensors 300 from each other.

[0055] 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.

[0056] The connection between the first housing 111 and the second housing 112 can be achieved using existing common screws.

[0057] 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 protrusions 120 and the like are provided on the first housing 111.

[0058] Preferably, a sealing strip 600 is provided between the first housing 111 and the second housing 112 to ensure the stability and service life of the external module.

[0059] In one embodiment, such as Figures 1 to 8 As shown, the connecting part is a connection point located at the lower part of the first housing 111, through which the external module can be connected to the smart wearable helmet; the connection interface is located downwards at the lower part of the housing (so that it can be inserted downwards into the smart wearable helmet).

[0060] Specifically, in this embodiment, the connection points are lugs 113 located at the front and rear of the first housing 111; the 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 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.

[0061] 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.

[0062] 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 external module and the smart wearable helmet.

[0063] In one embodiment, such as Figure 2 As shown, the housing (specifically the second housing 112 in this embodiment) has an arc surface matching the outer surface on the left / right (specifically the right side in this embodiment) outer surface of the smart wearable helmet B. This allows the external module to be installed more tightly on the smart wearable helmet, reducing the outer contour of the smart wearable helmet after the external module is installed, thereby reducing the impact on the wearer.

[0064] In addition, the external module of this application may also include output components (such as indicator lights / speakers (buzzers)) set on the motherboard to confirm whether the external module of this application has been correctly connected to the smart wearable helmet.

[0065] 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 external module.

[0066] 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.
