[0053] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below with reference to the accompanying drawings. In the drawings, the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout.

All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application. The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0054] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0055] In the description of this application, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not 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, they should not be construed as limitations on this application.

[0056] The terms "first," "second," "third," "fourth," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in a sequence other than those illustrated or described herein.

[0057] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or apparatus.

[0058] Inspection equipment is a widely used tool in industries such as manufacturing, construction, and energy. It is used to periodically inspect and monitor the condition of target objects or the environment to ensure their safety and normal operation. Existing inspection equipment can be divided into handheld inspection equipment, mobile inspection equipment (such as robots and drones), and head-mounted inspection equipment.

[0059] In related technologies, the head-mounted inspection equipment includes a hat and an inspection device; the inspection device is suspended on the outside of the hat by a buckle, and the inspection device has a built-in battery that powers the inspection operation of the device.

[0060] However, when using the aforementioned head-mounted inspection equipment, the inspection device is suspended on the outside of the hat via a buckle, causing it to be concentrated on one side of the hat. This results in a shift in the overall center of gravity and poor stability. Consequently, when the head-mounted inspection equipment is worn, it easily shifts with the user's head movements, affecting visibility and operational stability. Furthermore, since the battery is built into the inspection device, the entire device must be disassembled when the battery is depleted, which is inconvenient. Therefore, the overall user experience of the head-mounted inspection equipment is poor. Moreover, if personnel do not follow safety operating procedures and fail to properly fasten the head strap during use, a safety hazard may arise if objects fall from a height.

[0061] Therefore, head-mounted inspection equipment has the problems of poor user experience and potential safety hazards during use.

[0062] In view of this, this application provides a head-mounted inspection device. At least three mounting portions are spaced apart on the periphery of the headgear body. An inspection module, a battery module, and a headband detection module are detachably mounted on these mounting portions, one-to-one, with the inspection module and battery module facing each other, and the headband detection module and headband facing each other. The battery module powers the inspection module, which moves with the headgear body for inspection. This allows for easy replacement of the battery module when its power is low. When the headgear body is worn, the inspection module and battery module can be positioned on opposite sides of the person's direction of travel to maintain good balance. The headband detection module and headband are positioned on either side of the person's ears to prevent the headgear body from falling off after the person connects the headband and headband detection module. Furthermore, when the headgear body is worn, the headband detection module detects whether the connection between the connection and the headband is secure, providing safety monitoring and reducing safety hazards caused by the person forgetting to connect the connection during inspection. Overall, head-mounted inspection equipment offers a good user experience and can reduce safety hazards.

[0063] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0064] See Figures 1 to 3 The head-mounted inspection device provided in this application includes a hat body 100 and a detection device 200. The hat body 100 includes a hat body 110 and a hat strap (not shown) disposed on the hat body 110. The detection device 200 includes an inspection module 210, a battery module 230, and a hat strap detection module 220. The periphery of the hat body 110 has at least three mounting portions 111 spaced apart. The inspection module 210, the battery module 230, and the hat strap detection module 220 correspond one-to-one. The inspection module 210 and the battery module 230 are detachably mounted on the mounting part 111, and the hat strap detection module 220 is opposite to the hat strap. The battery module 230 is used to power the inspection module 210, and the inspection module 210 is used to move with the hat body 110 to perform inspection. The hat strap detection module 220 has a connecting part 221 that matches the hat strap. The hat strap detection module 220 is used to detect whether the connecting part 221 is connected to the hat strap after the hat body 110 is in the wearing state.

[0065] The shape and material of the helmet body 100 can be designed with reference to the structure of a safety helmet, and this application embodiment does not limit this.

[0066] Specifically, the hat body 110 serves as the basic load-bearing structure of the entire device, providing an installation platform for the inspection module 210, battery module 230, and hat strap detection module 220, while also providing space for personnel to wear the hat. The hat strap is used to connect to the hat strap detection module 220 via the connection part 221 to prevent the hat body 110 from slipping off the personnel's head.

[0067] The inspection module 210 is used to perform inspection tasks, including image acquisition, voice interaction, and lighting assistance. The battery module 230 provides power to the inspection module 210. The hat strap detection module 220 detects whether the connecting part 221 is connected to the hat strap after the hat body 110 is in the wearing state. The hat strap detection module 220 provides safety supervision and protection, reducing safety hazards caused by personnel forgetting to connect the connecting part 221 to the hat strap during the inspection process.

[0068] The mounting part 111 is used to position and install various functional modules, namely the inspection module 210, the battery module 230, and the hat strap detection module 220. For example, the mounting part 111 can be adaptively designed according to the hat body 110 and the corresponding functional modules, ensuring that after the inspection module 210, battery module 230, and hat strap detection module 220 are mounted on the hat body 110 via the corresponding mounting parts 111, the inner cavity of the hat body 110, i.e., the wearing space provided for the person's head, conforms to an ergonomic design, improving wearing comfort.

[0069] In practice, the mounting part 111 is a mounting slot or mounting hole.

[0070] Among them, the mounting part 111 corresponding to the inspection module 210 and the mounting part 111 corresponding to the battery module 230 are respectively located along the cap body 110. Figure 3 On both sides of the Y-direction shown, the cap body 110 has an inner cap wall and an outer cap wall. Both mounting portions 111 can be configured as mounting groove structures extending from the inner cap wall to the outer cap wall. After the inspection module 210 and battery module 230 are respectively placed on their corresponding mounting portions 111, the edge of the inspection module 210 and the inner cap wall form a relatively smooth connection, which helps improve the wearing comfort of the user's head. The mounting portion 111 corresponding to the cap strap detection module 220 is located along the cap body 110... Figure 3 On one side in the X direction shown, the mounting part 111 can be configured as a mounting hole structure formed between the inner cap wall and the outer cap wall.

[0071] It should be noted that, Figure 3 The Y direction shown indicates the direction of movement of the personnel wearing the head-mounted inspection equipment, and the X direction indicates the direction in which the personnel's left ear faces the right ear.

[0072] In practice, the inspection module 210, battery module 230 and hat strap detection module 220 can be detachably mounted on the corresponding mounting part 111 by means of screw connection, snap-fit ​​or magnetic connection, etc., and this application embodiment does not limit this.

[0073] In summary, the head-mounted inspection device provided in this application embodiment, by providing at least three mounting portions 111 spaced apart around the periphery of the hat body 110, detachably mounts the inspection module 210, battery module 230, and hat strap detection module 220 on the mounting portions 111, such that the inspection module 210 and battery module 230 are opposite each other, and the hat strap detection module 220 and hat strap are opposite each other. The battery module 230 is used to power the inspection module 210, and the inspection module 210 is used to move with the hat body 110 to perform inspections. Thus, when the battery module 230 is low on power, it can be easily disassembled and replaced. When the hat body 110 is worn, the inspection module 210 and the battery module 230 can be positioned on either side of the person's direction of travel, maintaining good balance. The hat strap detection module 220 and the hat strap are positioned on either side of the person's ears, preventing the hat body 110 from falling off after the person connects the hat strap and the connection part 221 of the hat strap detection module 220. Furthermore, when the hat body 110 is worn, the hat strap detection module 220 detects whether the connection part 221 is connected to the hat strap, providing safety supervision and reducing safety hazards caused by the person forgetting to connect the connection part 221 to the hat strap during the inspection process. Overall, the head-mounted inspection device offers a good user experience and reduces safety hazards.

[0074] See Figures 4 to 13 In some examples, the inspection module 210 includes a first circuit board 211, the hatband detection module 220 includes a second circuit board 222, and the battery module 230 includes a third circuit board 231; both the first circuit board 211 and the third circuit board 231 have a first wiring harness interface 2111, and both the first circuit board 211 and the second circuit board 222 have a second wiring harness interface 2112. The two first wiring harness interfaces 2111 are electrically connected through a first wiring harness (not shown in the figure), and the two second wiring harness interfaces 2112 are electrically connected through a second wiring harness (not shown in the figure).

[0075] Thus, the inspection module 210, battery module 230, and hat strap detection module 220 are all equipped with independent circuit systems, which can be developed, tested, and replaced individually. Through the design of the wiring harness interface, cameras 2131 with different performance in the inspection module 210 or batteries of different capacities in the battery module 230 can be replaced according to operational needs, improving the adaptability of the equipment. The inspection module 210 and battery module 230 are connected by a first wiring harness to ensure stable power supply. The inspection module 210 and hat strap detection module 220 are connected by a second wiring harness to ensure real-time feedback of wearing status monitoring data.

[0076] Specifically, the first circuit board 211 serves as the core control unit of the inspection module 210. Through a multi-functional integrated design, it carries functions such as image acquisition, voice processing, and lighting control. At the same time, it provides communication interfaces for the battery module 230 and the hat strap detection module 220.

[0077] The second circuit board 222 is connected to the inspection module 210 through the second wiring harness interface 2112. It can transmit the detection results of the hatband detection module 220 on whether the hatband and the connecting part 221 are connected to the inspection module 210 to determine whether the personnel have properly fastened the hatband during the inspection process and provide feedback.

[0078] The third circuit board 231 is connected to the inspection module 210 through the first wiring harness interface 2111, thereby establishing a power transmission channel between the inspection module 210 and the battery module 230 through the first wiring harness interface 2111, realizing the transmission of current and meeting the power consumption requirements of the inspection equipment.

[0079] See Figure 5 In some examples, the inspection module 210 further includes a first support member 212 and an inspection function component 213. The first support member 212 is detachably mounted on the corresponding mounting part 111. The inspection function component 213 and the first circuit board 211 are both mounted on the first support member 212. The inspection function component 213 includes at least one of a camera 2131, a speaker 2132, a keypad 2133, a microphone 2136, a light 2134, and an indicator light group 2135. The first circuit board 211 has a circuit sub-module (not shown) corresponding to and connected to at least one of the camera 2131, speaker 2132, keypad 2133, microphone 2136, light 2134, and indicator light group 2135.

[0080] Thus, by setting circuit sub-modules on the first circuit board 211, the inspection function component 213 and the first circuit board 211 can be integrated. Both the inspection function component 213 and the first circuit board 211 are integrated on the first support member 212. The first support member 212 is detachably installed on the mounting part 111, so that the entire inspection module 210 can be quickly assembled and disassembled as a complete unit, which is convenient for management. The circuit sub-modules on the first circuit board 211 can be expanded according to functional requirements, such as adding storage expansion modules, such as SD card slots, SIM card slots or TF card slots, to increase storage capacity, save more inspection data, and provide a hardware foundation for intelligent upgrades of the equipment.

[0081] Specifically, the inspection function component 213 is used to perform specific inspection tasks, collect inspection environment information, and realize human-computer interaction. Among them, the camera 2131 is used to realize image acquisition and remote video transmission; the speaker 2132 and microphone 2136 are used to realize voice intercom and environmental sound acquisition; the keypad 2133 is used to sense user input through physical buttons or capacitive touch to perform operations such as taking pictures through the first circuit board 211; the lighting 2134 is used to assist inspection work at night or in low light environments; and the indicator light group 2135 is used for status prompts, alarm displays, and other functions.

[0082] The button panel 2133 may include a camera button 206, a lighting button 207, a power button 208, and an emergency button 209. The indicator light group 2135 may include a power indicator light 2001, a charging indicator light 2002, and a fault indicator light 2003.

[0083] In specific implementation, depending on the specific type of the inspection function component 213, the circuit submodule can be configured as an actuator interface or a sensor interface to drive actuator-type functional components (such as speaker 2132, lighting 2134, indicator lights) or to collect sensor-type signals (such as image data from camera 2131, audio signals from microphone 2136).

[0084] For example, the circuit submodule corresponding to camera 2131 is an image sensing interface and an image signal processor (ISP) submodule, which receives the raw image output by camera 2131 through the image sensing interface and processes and optimizes it through the ISP submodule; the circuit submodule corresponding to speaker 2132 is an audio amplifier and a digital audio interface; the circuit submodule corresponding to keypad 2133 can be a general-purpose input / output (GPIO) control submodule 2114 or a touch detection circuit; the circuit submodule corresponding to microphone 2136 is a microphone 2136 preamplifier and an analog-to-digital converter (ADC) conversion circuit.

[0085] See Figure 7 In some embodiments, the inspection function component 213 includes a speaker 2132, a keypad 2133, a microphone 2136, and an indicator light group 2135. The first support member 212 includes a first support portion 2121, which includes a first support section 201 and a second support section 202 arranged sequentially. The first circuit board 211 is connected to the first support section 201. The speaker 2132, keypad 2133, microphone 2136, and indicator light group 2135 are all disposed on the second support section 202. There is an included angle between the first support section 201 and the second support section 202.

[0086] This configuration serves two purposes. First, it separates the heat-generating first circuit board 211 from the speaker 2132, button board 2133, microphone 2136, and indicator light group 2135, reducing the impact of heat on the microphone 2136, speaker 2132, etc. Second, after the first support member 212 is placed on the corresponding mounting part 111, the included angle between the first support section 201 and the second support section 202 helps the inspection module 210 fit the head contour more closely, avoiding local pressure and improving wearing stability and comfort.

[0087] For example, the first support segment 201 and the second support segment 202 can both be configured as follows: Figure 7 As shown in the plate-like structure, when the first support section 201 and the second support section 202 are mounted on the cap body 110 via the mounting part 111, the side of the first support section 201 opposite to the cap body 110 has an arc shape that matches the cap body 110, and the side of the second support section 202 opposite to the cap body 110 also has an arc shape that matches the cap body 110. This helps to reduce the overall impact of the first support member 212 on the inner cavity of the cap body 110, allowing the inner cavity of the cap body 110 to match the person's head.

[0088] In practice, the first circuit board 211 can be fixed to the first support section 201 with screws, then the speaker 2132, keypad 2133, microphone 2136 and indicator light group 2135 can be assembled onto the second support section 202, and finally the first support section 201 and the second support section 202 can be connected and assembled together with screws.

[0089] See Figure 8 Furthermore, the first support member 212 also includes a second support portion 2122, which is used to be mounted on the corresponding mounting portion 111. The second support portion 2122 has a first receiving cavity 203 with an opening 204 on one side, which is opposite to the cap opening of the cap body 110. The first support section 201 is located in the first receiving cavity 203, and the second support section 202 is connected to the second support portion 2122, and the second support section 202 covers the opening 204.

[0090] Thus, by hiding the first support section 201 in the receiving cavity of the second support section 2122, the second support section 202 and the inspection function component 213 on the second support section 202 are exposed, so as to facilitate user operation and sensory feedback of the inspection function component 213 on the second support section 202, and can avoid the first circuit board 211 being exposed, reducing the risk of accidental touch and bumps; and improving aesthetics.

[0091] For example, the second support portion 2122 can be configured as follows: Figure 8 The shell-like structure shown has a second support portion 2122 whose opposite side to the hat body 110 is arc-shaped and matches the hat body 110 when the hat body 110 is mounted on the hat body 110 via the mounting portion 111. As mentioned earlier, since both the first support segment 201 and the second support segment 202 have arc-shaped and matching sides to the hat body 110, it is beneficial to match the structure of the second support portion 2122 with that of the first support portion 2121, facilitating their assembly. Furthermore, the second support portion 2122 can reduce the overall influence of the first support member 212 on the inner cavity of the hat body 110, allowing the inner cavity of the hat body 110 to match the head of the person.

[0092] When the first circuit board 211 is disposed on the first support section 201, the first circuit board 211 has an along Figure 7 The diagram shows the left and right sides in the X direction, and the top and bottom sides along the Z direction. The first wiring harness interface 2111 is located on the upper side of the first circuit board 211 along the Z direction, and the second wiring harness interface 2112 is located on the right side of the first circuit board 211 along the X direction. Thus, as... Figure 6As shown, after the first support portion 2121 and the second support portion 2122 are assembled, wire harness holes 250 are provided on the second support portion 2122 at positions corresponding to the first wire harness interface 2111 and the second wire harness interface 2112, so that the first wire harness can be connected to the first wire harness interface 2111 through the wire harness hole 250, and the second wire harness can be connected to the second wire harness interface 2112 through the wire harness hole 250, thereby simplifying and optimizing the layout.

[0093] See Figure 5 and Figure 8 In a specific example, the inspection function component 213 also includes a camera 2131 and a light 2134. Both the camera 2131 and the light 2134 are connected to the side of the first support section 201 away from the first circuit board 211. The second support part 2122 and the peripheral sidewall of the hat body 110 are provided with first avoidance openings 205 for avoiding the camera 2131 and the light 2134. The camera 2131 and the light 2134 are exposed outside the hat body 110 through the first avoidance openings 205.

[0094] Thus, the overall layout design of the inspection module 210 is more reasonable, allowing the camera 2131 and the lighting lamp 2134 to be exposed to the outside of the cap body 110 without obstruction, thereby ensuring the normal functioning of the camera 2131 and the lighting lamp 2134, so that the camera 2131 can normally collect images of the external environment and the lighting lamp 2134 can provide supplementary lighting; reducing the problem of limited field of vision and insufficient lighting caused by structural obstruction.

[0095] See Figure 7 In some embodiments, the inspection module 210 further includes a backup battery 214; the backup battery 214 is disposed on the first support portion 2121 and is electrically connected to the first circuit board 211.

[0096] Thus, by setting up the backup battery 214, the usage time of the head-mounted inspection equipment in long-term operation scenarios can be increased, the interruption caused by frequent charging can be reduced, and the reliability of the system power supply can be improved.

[0097] In practical applications, the spare battery 214 can be detachably connected to the first support section 201 of the first support part 2121 by screws. The spare battery 214 can be a battery with a capacity of 300-500mAh, such as 300mAh, 400mAh or 500mAh.

[0098] See Figures 9 to 11In some examples, the hood strap detection module 220 further includes a second support member 223, which is detachably mounted on the corresponding mounting portion 111. The second support member 223 has a second receiving cavity 2231, and a second circuit board 222 is disposed in the second receiving cavity 2231. The second support member 223 has a second clearance opening 2232 communicating with the second receiving cavity 2231. The connecting portion 221 is slidably connected to the second support member 223, and part of the connecting portion 221 is placed in the second receiving cavity 2231 through the second clearance opening 2232. The connecting portion 221 is configured to move away from the second circuit board 222 when connected to the hood strap, and move towards the second circuit board 222 when disconnected from the hood strap.

[0099] Thus, by setting the second support member 223, the modular integrated design of the hatband detection module 220 is realized, making the overall structure of the hatband detection module 220 more compact; by setting the second circuit board 222 in the second receiving cavity 2231, the influence of external dust, moisture and other factors on the second circuit board 222 can be reduced, which is conducive to improving the service life and safety of the second circuit board 222.

[0100] By configuring the connecting portion 221 to move away from the second circuit board 222 when connected to the hatband, and to move closer to the second circuit board 222 when disconnected from the hatband, the connection structure between the connecting portion 221 and the hatband is simplified. For example, Figure 10 As shown, the connecting part 221 has a hook 2213, which is located outside the second receiving cavity 2231. When the hat strap is hooked to the hook 2213, the connecting part 221 will move away from the second circuit board 222 due to the pulling force of the hat strap.

[0101] The connecting part 221 may include a T-shaped rod, and the hook 2213 and the T-shaped rod may be integrally formed to form a more stable connection.

[0102] It should be noted that, as Figure 9 As shown, when the second circuit board 222 is disposed within the second receiving cavity 2231, a wire harness hole 250 is provided on the second support member 223, and the wire harness hole 250 is opposite to the second wire harness interface 2112 on the second circuit board 222. In this way, after one end of the second wire harness is connected to the second wire harness interface 2112 on the first circuit board 211, the other end can be connected to the second wire harness interface 2112 on the second circuit board 222 via the wire harness hole 250, which is beneficial for further simplifying and optimizing the layout.

[0103] In a specific example, the hood strap detection module 220 further includes an elastic element 224, and the connecting portion 221 is slidably connected to the second support member 223 through the elastic element 224; the elastic element 224 is configured to compress under the tension of the hood strap when the connecting portion 221 is connected to the hood strap, causing the connecting portion 221 to move away from the second circuit board 222; and to extend to drive the connecting portion 221 to move closer to the second circuit board 222 when the connecting portion 221 is disconnected from the hood strap.

[0104] Thus, the elastic element 224 provides a stable elastic force, ensuring that the sliding and resetting actions of the connecting part 221 are more reliable and improving the structural lifespan. At the same time, with the setting of the elastic element 224, personnel only need to hook or unhook the connecting part 221 and the hat strap to complete the wearing or unhooking operation of the head-mounted inspection equipment according to the specifications, which is smooth and provides a good experience.

[0105] The specific structure of the elastic element 224 is not limited in this embodiment. For example, the elastic element 224 can be a spring, a rubber pad, or an elastic silicone pillar. In this way, the elastic element 224 has a simple, lightweight structure and occupies little space, which simplifies the reset structure of the connecting part 221 and makes the hatband detection module 220 compact and small, which is beneficial to the lightweight design of the head-mounted inspection equipment.

[0106] Among them, such as Figure 10 As shown, the elastic element 224 is a spring, and there are two springs arranged symmetrically along the axis of the T-shaped rod. This facilitates smoother sliding and repositioning of the connecting part 221.

[0107] In some examples, the second circuit board 222 has a distance sensor 225; the connection part 221 includes a sensing section 2211 and a connecting section 2212 arranged in sequence, the sensing section 2211 is located in the second receiving cavity 2231, and the connecting section 2212 is used to connect or disconnect from the hatband to drive the sensing section 2211 to move relative to the distance sensor 225; the distance sensor 225 is used to detect whether the connecting section 2212 is connected to the hatband by detecting whether the distance between it and the sensing section 2211 reaches a preset value.

[0108] Thus, by setting the distance sensor 225, non-contact status detection can be achieved for the connection between the connecting section 2212 and the hood strap, which helps to improve detection accuracy, reduce mechanical wear, and improve the stability of the hood strap detection module 220.

[0109] Here, the preset value can be set according to the actual situation. For example, the preset value can be set to 7-8mm, such as 7mm, 7.5mm or 8mm.

[0110] When the connecting part 221 is in the reset state, the distance between the sensing section 2211 and the distance sensor 225 can be 5mm. When the connecting section 2212 is connected to the hatband, the sensing section 2211 moves 2-3mm away from the distance sensor 225 under the pulling force of the hatband, and the distance sensor 225 detects that the connecting section 2212 is connected to the hatband. When the connecting section 2212 is disconnected from the hatband, the connecting section 2212 drives the sensing section 2211 to reset, which reduces the distance between the sensing section 2211 and the distance sensor 225. Thus, the distance sensor 225 detects that the distance between the sensing section 2211 and the distance sensor 225 has not reached the preset value, and detects that the connecting section 2212 is not connected to the hatband.

[0111] In this embodiment, the connecting segment 2212 is a T-shaped rod structure as described above, and the sensing segment 2211 can be a metal magnet.

[0112] This application does not limit the specific type of distance sensor 225. For example, the distance sensor 225 can be set as an infrared proximity sensor, a capacitive sensor or a laser rangefinder sensor according to the application scenario.

[0113] See Figure 6 and Figure 7 Furthermore, the first circuit board 211 also has a wearing detection submodule 2113 and a control submodule 2114. The wearing detection submodule 2113 is located on the side of the first circuit board 211 away from the first support section 201. A through hole 2004 is opened on the second support part 2122. The first receiving cavity 203 is connected to the inner cavity of the hat body 110 through the through hole 2004. The wearing detection submodule 2113 is opposite to the through hole 2004. The wearing detection submodule 2113 and the distance sensor 225 are both electrically connected to the control submodule 2114. The wearing detection submodule 2113 is used to detect whether the hat body 110 is in a wearing state. The control submodule 2114 is used to wait for a preset time when the wearing detection submodule 2113 detects that the hat body 110 is in a wearing state, so as to control the distance sensor 225 to detect whether the connecting part 221 is connected to the hat strap.

[0114] Thus, by introducing a waiting mechanism through the control submodule 2114, after the wearing detection submodule 2113 confirms the wearing status, a certain time is delayed before the distance sensor 225 detects the connection status of the connection part 221 and the hood strap. This avoids misjudgment caused by the person just putting on the device and not yet fastening the hood strap, which helps to improve the reliability of the detection logic and the user experience.

[0115] The preset duration can be 5-7 seconds. For example, the preset duration can be set to 5 seconds, 6 seconds or 7 seconds.

[0116] For example, by placing the wear detection submodule 2113 on the side of the first circuit board 211 away from the first support section 201, and by opening a through hole 2004 on the second support portion 2122, the first receiving cavity 203 communicates with the inner cavity of the hat body 110 through the through hole 2004, and the wear detection submodule 2113 is opposite to the through hole 2004. In this way, after the inspection module 210 is connected to the hat body 110 through the corresponding mounting portion 111, it can be ensured that the wear detection submodule 2113 can normally sense the person's head to detect whether the hat body 110 is in a wearing state, reducing the interference of the second support portion 2122 and the hat body 110 on the detection of the wear detection submodule 2113.

[0117] Here, the specific type of the wear detection submodule 2113 is not limited in this embodiment of the application, as long as it can sense the head of the person. For example, the wear detection submodule 2113 is a light sensor module.

[0118] Thus, the optical sensor module has a compact structure that can meet the requirements of embedded installation. By embedding the optical sensor module into the through hole 2004, the optical sensor module can fit against the person's head when the hat body 110 is in the wearing state, and quickly respond to the wearing state of the hat body 110 for more accurate detection. Moreover, the detection process will not interfere with the normal wearing of the person, and the overall design is more reasonable.

[0119] In a specific implementation, the circuit submodule corresponding to the speaker 2132 is electrically connected to the control submodule 2114; the control submodule 2114 is configured to control the speaker 2132 to emit an audio alarm when the distance between the distance sensor 225 and the sensing segment 2211 is not detected by the distance sensor 225 and the sensing segment 2211 is not at a preset value.

[0120] With this setup, if personnel do not fasten their hat straps properly, an audio alarm will remind them to adjust the wearing of the hat body 110, thereby ensuring that the hat straps are properly connected to the connecting part 221. This helps to cultivate good usage habits and reduce safety hazards caused by not wearing hats during inspections.

[0121] It should be noted that, in specific implementations, other circuit submodules on the first circuit board 211 can also be electrically connected to the control submodule 2114. The following explanation uses the image-taking operation of the camera 2131 as an example.

[0122] Pressing the shutter button 206 on the button panel 2133 generates a level change signal, which is transmitted to the control submodule 2114 via the GPIO interface. Upon receiving the signal, the control submodule 2114 recognizes it as a shutter request. The control submodule 2114 sends a command to the image sensing interface, instructing the camera 2131 to start taking a picture. After receiving the command from the control submodule 2114, the image sensing interface activates the camera 2131 to acquire an image. After capturing the image, the camera 2131 transmits the raw image data back to the image sensing interface. The image sensing interface performs preliminary processing on the raw image data (such as noise reduction and color correction), and then transmits the processed image data to the control submodule 2114. The control submodule 2114 stores the processed image data in the storage expansion module.

[0123] See Figure 12 and Figure 13 In some embodiments, the battery module 230 further includes a battery body 232 and a battery spring holder 233; the battery body 232 is connected to the third circuit board 231 through the battery spring holder 233.

[0124] Thus, the battery spring holder 233 adopts an elastic contact structure, which can achieve a stable electrical connection between the battery and the circuit board without soldering, and facilitates quick insertion and removal of the battery body 232. In addition, the battery spring holder 233 has good conductivity and self-cleaning function, which can reduce contact resistance and help maintain stable current transmission in complex environments such as vibration and impact.

[0125] The battery body 232 can be a battery with a capacity of 4000-5000mAh, for example, the capacity of the battery body 232 is 4000mAh, 4500mAh or 5000mAh.

[0126] In practice, the battery spring holder 233 can be standardized according to the battery body 232 of different models and capacities to improve the versatility of the battery spring holder 233.

[0127] Furthermore, the battery module 230 also includes a third support member 234, which is used to be mounted on the corresponding mounting part 111. The third support member 234 has a third receiving cavity 2341. The third circuit board 231, the battery body 232 and the battery spring holder 233 are all placed in the third receiving cavity 2341. The third support member 234 has a third clearance opening 2342 that communicates with the third receiving cavity 2341. The third clearance opening 2342 is disposed opposite to the first wire harness interface 2111 on the third circuit board 231.

[0128] Thus, by setting the third support member 234, the modular integrated design of the battery module 230 is realized, making the overall structure of the cap strap detection module 220 more compact. By setting the third circuit board 231, the battery body 232 and the battery spring holder 233 in the third receiving cavity 2341, the influence of external dust, moisture and other factors on the third circuit board 231, the battery body 232 and the battery spring holder 233 can be reduced, thereby improving service life and safety.

[0129] With the design of the third clearance port 2342, after one end of the first wire harness is connected to the first wire harness interface 2111 on the first circuit board 211, the other end can be connected to the first wire harness interface 2111 on the third circuit board 231 via the third clearance port 2342. This helps to simplify and optimize the layout and avoid the first wire harness interface 2111 from becoming loose due to bending or pulling of the first wire harness.

[0130] See Figure 4 In a specific implementation, the head-mounted inspection device also includes a pressure plate assembly 300, which includes a first pressure plate member 310 and a second pressure plate member 320. The first pressure plate member 310 has a first placement groove (not shown) that matches the first wire harness, and the first wire harness is placed in the first placement groove. The first pressure plate member 310 is connected to the cap body 110 to attach the first wire harness to the cap body 110. The second pressure plate member 320 has a second placement groove (not shown) that matches the second wire harness, and the second wire harness is placed in the second placement groove. The second pressure plate member 320 is connected to the cap body 110 to attach the second wire harness to the cap body 110.

[0131] In this way, the first pressure plate 310 and the second pressure plate 320 respectively organize the first wire harness and the second wire harness, avoiding the first wire harness and the second wire harness from being exposed or hanging and rubbing against the head of the personnel, thereby improving the appearance and wearing experience of the head-mounted inspection equipment.

[0132] For example, the structure of the first pressure plate 310 and the second pressure plate 320 matches the contour of the cap body 110. By confining the first wire harness in the first placement groove and the second wire harness in the second placement groove, the first wire harness and the second wire harness are made to fit the cap body 110, thereby helping to reduce functional interruption or safety hazards caused by shaking and pulling.

[0133] The first pressure plate 310 and the second pressure plate 320 are both connected to the cap body 110 by screws.

[0134] See Figure 2 and Figure 3In some embodiments, the detection device 200 further includes a gas detection module 240; the circumference of the cap body 110 has four spaced mounting portions 111, the cap strap and the mounting portion 111 corresponding to the gas detection module 240 are located on the same side of the cap body 110, and the gas detection module 240 is mounted on the corresponding mounting portion 111 so as to be opposite to the cap strap detection module 220; the gas detection module 240 is used to detect gas information in the inspection environment, wherein the gas information includes at least one of gas concentration and gas type.

[0135] Thus, the gas detection module 240 and the hatband detection module 220 are arranged opposite each other on the hat body 110, which is a reasonable layout that facilitates wiring and improves wearing comfort and overall aesthetics. By detecting at least one of the gas concentration and gas type through the gas detection module 240, it is beneficial to take measures to prevent safety accidents such as poisoning, suffocation, and explosion when gas anomalies are detected.

[0136] It is understood that the structure of the gas detection module 240 can be adapted to the specific structure of the aforementioned cap strap detection module 220. For example, the gas detection module 240 may include a housing, a circuit board, a wiring harness interface, and a sensor for detecting gas information. This embodiment will not elaborate further on this aspect.

[0137] This application does not limit the gas concentration or gas type in its embodiments. For example, the gas type detected by the gas detection module 240 may include combustible gas (methane, propane), irritating gas (chlorine), and toxic gas (sulfur dioxide), and the gas concentration may be oxygen concentration.

[0138] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
