Description

Technical Field

[0001] This utility model relates to the field of safety protection equipment technology, and in particular to a smart safety helmet based on visual recognition. Background Technology

[0002] In industrial work scenarios such as construction, power, and mining, safety helmets are crucial equipment for ensuring the head safety of workers. As the demand for real-time monitoring, environmental perception, and safety warnings in work environments increases, smart safety helmets integrating visual recognition functions (such as image acquisition and lighting) are gradually being adopted. However, existing smart safety helmets still have many problems in practical use: The lighting and camera module installation structure of some products is not reasonably designed, and the fixing reliability between the module and the mounting carrier is insufficient. During operation, it is easy to loosen due to factors such as vibration, resulting in functional failure. At the same time, the installation and disassembly of existing modules are relatively cumbersome. Maintenance or replacement of modules often requires the use of multiple tools, which is time-consuming and affects work efficiency.

[0003] To address the aforementioned issues, this utility model document proposes a smart safety helmet based on visual recognition. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as unreasonable installation structures of lighting and camera modules, loose fixing, and cumbersome and time-consuming disassembly and assembly, which affect operations. Therefore, this invention proposes a smart safety helmet based on visual recognition.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A smart safety helmet based on visual recognition includes a helmet body. A mounting box is fixedly installed on the top of the helmet body near the brim. Two light-emitting camera modules are arranged vertically inside the mounting box. Each light-emitting camera module consists of a module body and a transparent panel. The transparent panel is fixedly installed on one side of the module body. The module body is located inside the mounting box, and the transparent panel is located outside the mounting box. It also includes a locking assembly, which includes two locking plates fixedly installed on the side of the two module bodies away from the transparent panel. Each of the two locking plates has a positioning groove on one side. A locking rod is rotatably passed through the inside of the mounting box. The locking rod corresponds to the light-emitting camera module located above. The locking rod is located in the positioning groove of the adjacent locking plate, and its outer wall is slidably engaged with the inner wall of the corresponding positioning groove. Two clearance grooves are opened on one side of the circumferential outer wall of the locking rod. Both clearance grooves correspond to the corresponding positioning grooves, and the inner walls of both clearance grooves are slidably engaged with the outer walls of the corresponding locking plates. The lighting camera module can be quickly installed and removed by rotating the locking lever to align the clearance slot with the locking plate.

[0006] In one possible design, two limiting strips are fixedly installed on both sides of the two module bodies, and two limiting grooves are opened on both sides of the inner wall of the mounting box. The multiple limiting strips are slidably connected to the inner wall of the corresponding limiting groove.

[0007] In one possible design, the locking assembly further includes two mounting plates fixedly installed at both ends of the locking rod. Both mounting plates are located outside the mounting box. Each of the two mounting plates has a threaded hole near its ends. Each of the two mounting plates has at least one abutting screw on one side. One end of the abutting screw is threaded through the corresponding threaded hole, and both abutting screws abut against the outer wall of the mounting box.

[0008] In one possible design, both outer walls of the mounting box are provided with arc-shaped grooves, and one end of each of the two abutting screws extends into the adjacent arc-shaped groove and abuts against the inner wall of the arc-shaped groove. Both arc-shaped grooves are semi-annular grooves.

[0009] In one possible design, both of the light-emitting camera modules have slots on their tops, and both of the light-emitting camera modules have protrusions fixedly installed on their bottoms, the protrusions engaging with the slots on the tops of the adjacent light-emitting camera modules.

[0010] In one possible design, the top of the mounting box is hinged with a movable cover, one end of which is fixedly fitted with a buckle plate, which engages with a slot on the top of the upper illumination camera module.

[0011] In one possible design, a control box is fixedly installed on the top of the helmet body away from the brim, and the control box is electrically connected to two light-emitting camera modules.

[0012] In one possible design, a warning light strip is fixedly embedded on one side of the outer wall of the control box.

[0013] In this application, when a user wears the smart helmet, two illumination camera modules inside the mounting box at the top of the helmet body activate. The transparent panels of the illumination camera modules allow light to pass through and provide illumination, while the image acquisition components within the module body capture images of the surrounding environment. The two modules are arranged vertically, covering different angles of the field of view, ensuring comprehensive illumination and image acquisition.

[0014] The locking mechanism inside the mounting box ensures the stable fixation of the lighting camera modules. During module installation, the limiting strips on both sides of the module body slide along the limiting grooves on the inner wall of the mounting box, guiding the two modules to be placed into the box sequentially. Simultaneously, rotating the locking lever aligns its clearance groove with the locking plate, allowing the module body to move smoothly up and down during installation without interference. After installation, the locking lever is positioned on the side closest to the upper module body, and it is located in the positioning grooves of the corresponding two locking plates. Then, rotating the locking lever another 180 degrees moves the two clearance grooves away from the two locking plates. At this point, the locking lever vertically restricts the locking plates, ensuring the stable installation of the two lighting camera modules within the mounting box.

[0015] Next, adjust the abutment screws on the mounting plate to press them against the outer wall of the mounting box. This increases the friction when the locking lever rotates, preventing accidental loosening. The end of the abutment screw abuts against the arc-shaped groove on the outer wall of the mounting box, which limits the rotation range of the locking lever and ensures reliable locking.

[0016] This structure allows for the removal or installation of the module's contact restriction by rotating the locking rod to align or offset its clearance groove with the locking plate, facilitating quick disassembly or installation.

[0017] Meanwhile, the two illumination camera modules engage with each other via top slots and bottom protrusions, maintaining vertical stability. The hinged cover is attached to the top of the mounting box; when closed, its latch engages with the slot of the upper module, further sealing the mounting box. The control box is electrically connected to the illumination camera modules, receiving and processing image data; based on the processing results, it controls the flashing of warning light strips to provide visual warnings to personnel behind, enhancing operational safety. The entire operation achieves continuous environmental monitoring and warning functions through the coordinated operation of all components.

[0018] Beneficial effects: In this utility model, the intelligent safety helmet based on visual recognition effectively expands the coverage of environmental monitoring through the vertical arrangement of dual-light-illumination camera modules; the two modules work together to achieve image acquisition and illumination in front of the workers, which can reduce blind spots and thus improve the comprehensiveness and accuracy of monitoring the work site environment. In this invention, the smart safety helmet based on visual recognition uses a locking component that controls the relative position of its clearance groove and the locking plate by rotating the locking rod, thereby enabling the module to be quickly locked or released. This structure simplifies the installation and disassembly process and ensures that the module can maintain a stable connection under vibration, thus improving the overall structure's seismic performance. In this invention, the smart safety helmet based on visual recognition features a limiting strip and a limiting groove that work together to ensure stability during module installation and prevent the module from shaking after installation. The slots and protrusions between modules prevent relative displacement and ensure stable vertical alignment between modules. The movable cover engages with the module via a snap-on plate, providing additional fixation and improving the sealing effect of the mounting box.

[0019] In this invention, the intelligent safety helmet based on visual recognition achieves complete functionality through the cooperation of the control box and the warning light strip. The system can process the collected image data in real time and drive the warning light strip to emit visual signals based on the processing results, so as to promptly transmit safety status information to the surrounding personnel and enhance the proactive early warning capability of the work site. In this invention, the safety helmet enhances visual recognition performance through the vertical layout of the dual-light imaging module. At the same time, the locking rod and locking plate work together to achieve quick disassembly and stable locking of the module. The combination of the limiting structure and the movable cover improves the overall installation stability and sealing. Furthermore, the coordinated work of the control box and the warning light strip enhances the on-site early warning capability, thereby comprehensively improving the monitoring reliability and ease of use of the safety helmet.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] In one embodiment: Refer to Figure 1-5 A smart safety helmet, comprising: The safety helmet body 1 has a mounting box 2 fixedly installed on the top of the safety helmet body 1 near the brim. Two lighting camera modules 4 are vertically arranged inside the mounting box 2. These two lighting camera modules 4 are used to perform lighting and image acquisition tasks. The lighting camera module 4 consists of an LED light and a camera, both of which are conventional components in existing technology.

[0024] In this embodiment, each light-emitting camera module 4 consists of a module body 7 and a transparent panel 8. The transparent panel 8 is fixedly installed on one side of the module body 7. The module body 7 is set inside the mounting box 2, and the transparent panel 8 is located outside the mounting box 2, with its two sides protruding from the module body 7 to achieve a tight fit with the edge of the mounting box 2.

[0025] To ensure the stable installation of the two light-emitting camera modules 4 in the mounting box 2, in this embodiment, two limiting strips 14 are fixedly installed on both sides of the two module bodies 7, and two limiting grooves 10 are opened on the inner walls of both sides of the mounting box 2, and the multiple limiting strips 14 are slidably connected to the inner walls of the corresponding limiting grooves 10.

[0026] In this embodiment, a locking assembly is also provided to securely install the two illumination camera modules 4 within the mounting box 2. The locking assembly includes two locking plates 15 fixedly installed on the side of the two module bodies 7 away from the transparent panel 8. Each locking plate 15 has a positioning groove 16 on one side. A locking rod 17 rotatably passes through the mounting box 2, corresponding to the illumination camera module 4 located above. The locking rod 17 is positioned within the positioning groove 16 of the adjacent locking plate 15, and its outer wall slides against the inner wall of the corresponding positioning groove 16. Two clearance grooves 18 are formed on one side of the outer circumference of the locking rod 17. Both clearance grooves 18 correspond to the corresponding positioning grooves 16, and the depth of the clearance grooves 18 is the same as the depth of the positioning grooves 16. The inner walls of both clearance grooves 18 slide against the outer walls of the corresponding locking plates 15. When the locking lever 17 rotates to the point where the two clearance slots 18 correspond to the movement path of the corresponding locking plate 15, the corresponding locking plate 15 can pass through the clearance slots 18 to complete the lifting and lowering, thereby releasing the abutment restriction on the adjacent locking plate 15.

[0027] In this embodiment, the locking assembly further includes two mounting plates 19 fixedly installed at both ends of the locking rod 17, both mounting plates 19 being located outside the mounting box 2. Threaded holes 20 are provided on both mounting plates 19 near their ends, and at least one abutting screw 21 is provided on one side of each mounting plate 19. One end of the abutting screw 21 is threaded through the corresponding threaded hole 20, and both abutting screws 21 abut against the outer wall of the mounting box 2, thereby increasing the frictional force when the locking rod 17 rotates.

[0028] This application can be used in the field of safety protection equipment technology, or in other fields applicable to this application.

[0029] In another embodiment: Reference Figure 2 , 3 4. A smart safety helmet based on visual recognition, which is applied to the field of safety protection equipment technology; In this embodiment, arc-shaped grooves 11 are formed on both outer walls of the mounting box 2, and one end of each of the two abutting screws 21 extends into the adjacent arc-shaped grooves 11 and abuts against the inner wall of the arc-shaped grooves 11. Both arc-shaped grooves 11 are semi-annular grooves used to limit the rotation angle of the locking rod 17.

[0030] In this embodiment, when the locking lever 17 is rotated to the locked position, the abutment screw 21 should be located near the bottom of the mounting plate 19 to ensure that the rotating lever 17 will not rotate arbitrarily under the action of gravity.

[0031] In this embodiment, slots 12 are provided on the top of both light-emitting camera modules 4, and protrusions 13 are fixedly installed on the bottom of both light-emitting camera modules 4. The protrusions 13 engage with the slots 12 on the top of the adjacent light-emitting camera modules 4 to achieve connection and fixation between the upper and lower light-emitting camera modules 4.

[0032] In this embodiment, a movable cover 3 is hinged to the top of the mounting box 2, which is used to close the top of the mounting box 2. A mounting plate 9 is fixedly installed at one end of the movable cover 3. The mounting plate 9 engages with the slot 12 on the top of the upper illumination camera module 4, further enhancing the stability of the illumination camera module 4 within the mounting box 2.

[0033] In this embodiment, a control box 5 is fixedly installed on the top side of the safety helmet body 1 away from the brim. The control box 5 is electrically connected to two light-emitting camera modules 4. A warning light strip 6 is fixedly embedded on one outer wall of the control box 5. The warning light strip 6 is used to provide a warning to people behind.

[0034] However, as is well known to those skilled in the art, the working principles and wiring methods of the illumination camera module 4 and the warning light strip 6 are conventional methods or common knowledge, and will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0035] The working principle and usage process of this technical solution are as follows: When a user wears the smart safety helmet, the two illumination camera modules 4 inside the mounting box 2 at the top of the helmet body 1 are activated. The transparent panel 8 of the illumination camera module 4 allows light to pass through and provides illumination, while the image acquisition component inside the module body 7 captures images of the surrounding environment. The two modules are arranged vertically, which can cover the field of view at different angles, ensuring comprehensive illumination and image acquisition.

[0036] The locking mechanism inside the mounting box 2 ensures the stable fixation of the light-emitting camera module 4. During module installation, the limiting strips 14 on both sides of the module body 7 slide along the limiting grooves 10 on the inner wall of the mounting box 2, guiding the two modules to be placed into the mounting box 2 sequentially. Simultaneously, by rotating the locking rod 17 to align its clearance groove 18 with the locking plate 15, the module body 7 can move smoothly up and down during installation without interference. After installation, the locking rod 17 is positioned on the side closest to the upper module body 7, and it is located in the positioning grooves 16 of the corresponding two locking plates 15. Then, the locking rod 17 is rotated 180 degrees again, moving the two clearance grooves 18 away from the two locking plates 15. At this point, the locking rod 17 can vertically restrict the locking plates 15, thus ensuring the stable installation of the two light-emitting camera modules 4 within the mounting box 2.

[0037] Afterwards, adjust the abutment screw 21 on the mounting plate 19 to make it press against the outer wall of the mounting box 2, which can increase the friction when the locking rod 17 rotates and prevent accidental loosening; the end of the abutment screw 21 abuts against the arc groove 11 on the outer wall of the mounting box 2, which can limit the rotation range of the locking rod 17 and ensure reliable locking.

[0038] This structure allows the locking rod 17 to be rotated so that its clearance groove 18 is aligned with or offset from the locking plate 15, thereby releasing or enabling the module to abut, facilitating quick disassembly or installation.

[0039] Meanwhile, the two illumination camera modules 4 engage with each other via the top slot 12 and the bottom protrusion 13, maintaining the stability of their vertical alignment. The movable cover 3 is hinged to the top of the mounting box 2; when closed, its latch 9 engages with the slot 12 of the upper module, further sealing the mounting box 2. The control box 5 is electrically connected to the illumination camera modules 4, receiving and processing image data; based on the processing results, it controls the warning light strip 6 to flash, providing a visual warning to personnel behind, thus improving operational safety. The entire working process achieves continuous environmental monitoring and warning functions through the coordinated operation of all components.

[0040] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
