Description

Technical Field

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

[0002] With the widespread application of intelligent technology in industrial safety production, smart safety helmets are gradually becoming key equipment for ensuring worker safety and improving work collaboration efficiency. These helmets typically integrate electronic components such as microphones, control boards, positioning elements, and sensors to enable functions such as voice communication and environmental monitoring. The stable installation of these electronic components and the neat layout of the wiring directly affect the reliability and wearing comfort of the smart safety helmet.

[0003] Currently, the installation of electronic components in smart safety helmets mostly adopts simple brackets or is directly fixed inside the helmet body. The microphone installation and wiring are not optimized for sound reception, and there is no dedicated wiring for the connecting wires of the electronic components on the safety helmet. Utility Model Content

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes an intelligent safety helmet bracket.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A smart helmet bracket includes: a first inner cover with a first electronic component mounting structure on its outer side; a second inner cover spaced apart from the first inner cover with a second electronic component mounting structure on its outer side; a connecting strip for connecting the first and second inner covers, with a main cable channel on its outer side; and a mounting strip disposed between the first and second inner covers. The mounting strip has an upward-opening microphone mounting slot at its bottom, a sound hole extending to the bottom, and a branch cable channel communicating with the microphone mounting slot on its outer side, the branch cable channel communicating with the main cable channel.

[0007] Furthermore, it also includes a third inner cover, which has a third electronic component mounting structure; the third inner cover is located between the first inner cover and the second inner cover, and there are two connecting strips to connect the first inner cover and the third inner cover, and the second inner cover and the third inner cover, respectively.

[0008] Furthermore, the mounting strip includes an extension and a mounting portion, the mounting portion at least partially protruding outward from the extension; the upper end of the extension is connected to the third inner cover and / or a connecting strip, and the lower end is connected to the mounting portion; the microphone mounting slot is located in the mounting portion, and the cable tray is located in the extension.

[0009] Furthermore, at least one of the first inner cover, the second inner cover, and the third inner cover has an insertion block at its upper end.

[0010] Furthermore, at least one end of the connecting strip is detachably connected to the corresponding first inner cover, second inner cover, or third inner cover.

[0011] Furthermore, one end of the connecting strip is integrally connected to the side of the third inner cover, and the other end is detachably connected to the first inner cover or the second inner cover.

[0012] Furthermore, the first inner cover and the second inner cover are provided with a first protrusion on their opposing sides; a connecting inner protrusion is provided in the main through groove at the end of the connecting strip away from the third inner cover, and a buckle hole is provided on the connecting inner protrusion. A buckle is provided at the outer end of the first protrusion, the buckle is embedded in the buckle hole, and the end of the buckle is provided with a locking protrusion that passes through the buckle hole.

[0013] Furthermore, the first inner cover, the second inner cover, the connecting strip, and the third inner cover are integrally formed and connected.

[0014] Furthermore, the second electronic component mounting structure includes a limiting protrusion provided on the outer wall of the second inner cover, and the end of the limiting protrusion away from the second inner cover is provided with a limiting protrusion protruding from the side of the limiting protrusion.

[0015] Furthermore, the main cable tray has an outer opening, and a reinforcing rib is connected between two opposite sidewalls on the opening side of the main cable tray. The reinforcing rib and the inner wall of the main cable tray define a cable hole.

[0016] This utility model has the following beneficial effects:

[0017] The first electronic component mounting structure on the outer side of the first inner cover and the second electronic component mounting structure on the outer side of the second inner cover allow for targeted positioning or fixation of different electronic components such as the control board, battery, and sensors. This prevents electronic components from shaking or shifting during helmet use due to the lack of dedicated mounting structures, thus improving the stability of electronic component installation. The main cable channel on the outer side of the connecting strip connects to the branch cable channel on the outer side of the mounting strip, and the branch cable channel is connected to the microphone mounting slot, forming a dedicated cable storage channel. This allows the microphone connection cable to be neatly stored in the branch cable channel, while the connection cables of other electronic components are neatly stored in the main cable channel. This solves the problem of messy cable distribution in existing technologies, avoids interference or wear between the cable and other components, reduces the risk of poor cable contact, and improves the utilization of the helmet's internal space, ensuring wearing comfort. The mounting strip is located between the first and second inner covers. When assembled into the helmet, it is positioned in the middle of the helmet, corresponding to the mouth position in the middle of the head. The microphone is mounted at the bottom of the mounting strip, allowing the microphone to be closer to the mouth for better sound pickup. The microphone mounting slot provides a dedicated installation space for the microphone. Combined with the sound passage hole at the bottom of the microphone mounting slot, it allows external sounds to enter the microphone more smoothly, effectively solving the problem of insufficient microphone sound pickup clarity in existing technologies. It is especially suitable for noisy industrial environments.

[0018] In addition to the objectives, features, and advantages described above, this utility model has other objectives, features, and advantages. The present utility model will now be described in further detail with reference to the figures. Attached Figure Description

[0042] Please refer to Figure 1 and Figure 2 This utility model provides a preferred embodiment of a smart safety helmet bracket. The bracket is used to mount electronic components and related structures and wiring harnesses. During installation, the first inner cover 100, the second inner cover 200, the connecting strip 300, and the hanging strip 400 are all fitted against the inner wall of the smart safety helmet, thereby encasing and protecting the electronic components. Both the bracket and the smart safety helmet can be considered as part of the mounting shell for the electronic components. Using the safety helmet body as part of the shell for the electronic components, compared to the bracket being a complete shell installed entirely inside the safety helmet, makes the overall structure more compact. The smart safety helmet bracket includes a first inner cover 100, a second inner cover 200, a connecting strip 300, and a hanging strip 400. The outer sides of the first inner cover 100, the second inner cover 200, the connecting strip 300, and the hanging strip 400 are all designed to fit against the inner wall of the smart safety helmet.

[0043] A first electronic component mounting structure is provided on the outer side of the first inner cover 100. A second inner cover 200 is spaced apart from the first inner cover 100, and a second electronic component mounting structure is provided on the outer side of the second inner cover 200. A connecting strip 300 is used to connect the first inner cover 100 and the second inner cover 200, and a main cable channel 310 is provided on the outer side of the connecting strip 300. A mounting strip 400 is provided between the first inner cover 100 and the second inner cover 200; the bottom of the mounting strip 400 is provided with an upward-opening microphone mounting slot 410, which can mount a microphone 401. The microphone mounting slot 410 is provided with a sound hole 411 extending to the bottom, and a branch cable channel 420 communicating with the microphone mounting slot 410 is provided on the outer side of the mounting strip 400, which is connected to the main cable channel 310.

[0044] This utility model provides an intelligent safety helmet bracket. Through a first electronic component mounting structure on the outer side of the first inner cover 100 and a second electronic component mounting structure on the outer side of the second inner cover 200, different electronic components such as the control board, battery, and sensors can be specifically positioned or fixed. This prevents electronic components from shaking or shifting during helmet use due to the lack of dedicated mounting structures, thus improving the stability of electronic component installation. The main cable channel 310 on the outer side of the connecting strip 300 is connected to the branch cable channel 420 on the outer side of the hanging strip 400, and the branch cable channel 420 is connected to the microphone mounting slot 410, forming a dedicated cable storage channel. This allows the microphone connection cable to be neatly stored in the branch cable channel 420, and the connection cables of other electronic components to be neatly stored in the main cable channel 310. This solves the problem of messy cable distribution in existing technologies, avoids interference or wear between cable cables and other components, reduces the risk of poor cable contact, and improves the utilization rate of the helmet's internal space, ensuring wearing comfort. When worn, the first inner cover 100 and the second inner cover 200 are located on the left and right sides of the head. The mounting strip 400 is positioned between the first inner cover 100 and the second inner cover 200. When assembled into a helmet, the mounting strip 400 is located in the middle of the helmet, corresponding to the mouth position in the middle of the head, making it closer to the mouth for clearer sound pickup. Furthermore, a microphone is mounted at the bottom of the mounting strip 400, allowing the microphone to be even closer to the mouth for better sound pickup. The microphone mounting slot 410 provides dedicated mounting space for the microphone. Combined with the sound passage hole 411 at the bottom of the microphone mounting slot 410, external sounds can be transmitted to the microphone more smoothly, effectively solving the problem of insufficient microphone clarity in existing technologies, and is especially suitable for noisy industrial environments.

[0045] Reference Figure 1In some embodiments of this utility model, a third inner cover 500 is further included, which has a third electronic component mounting structure. The third inner cover 500 is located between the first inner cover 100 and the second inner cover 200. Two connecting strips 300 are provided to connect the first inner cover 100 and the third inner cover 500, and the second inner cover 200 and the third inner cover 500, respectively. The first inner cover 100 and the third inner cover 500 are connected by a connecting strip 300, and the second inner cover 200 and the third inner cover 500 are connected by another connecting strip 300. The outer sides of the first inner cover 100, the second inner cover 200, and the third inner cover 500 are all recessed to form concave cavities. The main through-line groove 310 can connect the concave cavities of the three inner covers in series, and the electronic components on the three inner covers can be connected by wire harnesses. The third inner cover 500 and its corresponding third electronic component mounting structure further expand the electronic component mounting space, accommodating more electronic components such as positioning modules, antenna modules, and additional sensors, thus improving the compatibility of the bracket with the functional expansion of the smart helmet. Simultaneously, two connecting strips 300 connect the first inner cover 100, the second inner cover 200, and the third inner cover 500 in series, forming a symmetrical and stable connection structure, enhancing the overall load-bearing strength of the bracket. Furthermore, by separately mounting multiple electronic components on the three inner covers, different functional electronic devices (such as sensors, positioning modules, communication modules, and battery packs) can be installed in different inner covers, avoiding the excessive space occupied by centralized installation. Separate installation allows for flattening, preventing the space occupied by a single location from protruding excessively from the helmet's interior, affecting the internal structure and wearing comfort. Placing each electronic component in an independent electronic component mounting cavity effectively reduces mutual interference between different components. The third electronic component mounting structure can specifically be a positioning strip 510 and a connecting post 520 with threaded holes, thereby achieving positioning and installation and fixation by screws.

[0046] Reference Figure 1 and Figure 2In some embodiments of this utility model, the mounting strip 400 includes an extension 430 and a mounting portion 440, with the mounting portion 440 at least partially protruding outward from the extension 430. The upper end of the extension 430 is connected to a third inner cover 500 and / or a connecting strip 300. In this embodiment, the upper end of the extension 430 is connected to the third inner cover 500 and the connecting strip 300, at the connection point between the third inner cover 500 and the connecting strip 300. Of course, in other embodiments, the upper end of the extension 430 may also be connected to the third inner cover 500 or a connecting strip 300. The lower end of the extension 430 is connected to the mounting portion 440; a microphone mounting slot 410 is provided in the mounting portion 440, and a cable tray 420 is provided in the extension 430. The mounting strip 400 is divided into an extension 430 and a mounting portion 440, with the mounting portion 440 partially protruding outward from the extension 430, as shown below. Figure 7 As shown, the mounting portion 440 protrudes beyond the extension portion 430, allowing the upper end of the mounting portion 440 to contact the brim 910 on the front side of the helmet body 900 during installation, thus improving installation stability. Furthermore, since the microphone mounting slot 410 at the mounting portion 440 faces upwards, the brim 910 can be provided with a locking protrusion that embeds into the microphone mounting slot 410, avoiding contact with the microphone 401. The locking protrusion can restrict the displacement of the mounting portion 440 in the horizontal direction, preventing damage to the mounting portion 440 due to its cantilever structure.

[0047] In some specific embodiments of this utility model, at least one of the first inner cover 100, the second inner cover 200, and the third inner cover 500 is provided with an insertion block 600 at its upper end. The insertion block 600 can cooperate with the slot structure inside the smart safety helmet body 900 to realize the quick positioning and installation of the bracket and the helmet body, facilitate the installation of screws after the hole is aligned, and the insertion block 600 can also enhance the connection stability between the bracket and the helmet body.

[0048] In some embodiments of this utility model, at least one end of the connecting strip 300 is detachably connected to the corresponding first inner cover 100, second inner cover 200, or third inner cover 500. This allows for independent manufacturing, facilitating mold manufacturing and reducing manufacturing difficulty.

[0049] Of course, in some other embodiments, such as Figure 3 As shown, the first inner cover 100, the second inner cover 200, the connecting strip 300 and the third inner cover 500 are integrally formed and connected, thereby reducing subsequent assembly steps and the number of parts.

[0050] Reference Figure 4 and Figure 5In a specific embodiment of this utility model, one end of the connecting strip 300 is integrally connected to the side of the third inner cover 500, and the other end is detachably connected to the first inner cover 100 or the second inner cover. That is, one end of one connecting strip 300 is detachably connected to the first inner cover 100, and the other end is integrally connected to the left side of the third inner cover 500; one end of the other connecting strip 300 is detachably connected to the second inner cover, and the other end is integrally connected to the right side of the third inner cover 500.

[0051] Reference Figure 5 and Figure 6 In a further embodiment of the present invention, a first protrusion 700 is provided on the opposing side of the first inner cover 100 and the second inner cover 200; a connecting inner protrusion 320 is provided in the main through groove 310 at the end of the connecting strip 300 away from the third inner cover 500, and a buckle hole is provided on the connecting inner protrusion 320; a buckle 710 is provided at the outer end of the first protrusion 700, the buckle 710 is embedded in the buckle hole, and the end of the buckle 710 is provided with a locking protrusion 711 that passes through the buckle hole. A snap-fit ​​structure is used to connect the connecting strip 300 and the first protrusion 700. Compared with screws and other fixing methods, disassembly and assembly can be completed without tools, greatly improving the convenience of bracket assembly and maintenance. A connecting inner protrusion 320 is set in the main cable channel 310 of the connecting strip 300, and it cooperates with the snap-fit ​​710 of the first protrusion 700 through the snap-fit ​​hole. The snap-fit ​​structure can be integrated into the main cable channel 310, avoiding the structure from being exposed and occupying space. At the same time, the main cable channel 310 can protect the snap-fit ​​structure. On the other hand, the locking protrusion 711 can realize the anti-disengagement locking of the snap-fit ​​710 and the snap-fit ​​hole, further enhancing the connection stability. The first protrusion 700 provides a large space for the snap-fit ​​710 without affecting the installation of electronic components on the inner cover and without interfering with the electronic components on the inner cover. In addition, to improve the tightness of the connection and the positioning accuracy, the end of the first protrusion 700 and the end of the connecting strip 300 are fitted with a concave-convex fit. For example, the end of the first protrusion 700 is provided with a positioning protrusion, and the end of the connecting strip 300 is provided with a stepped groove that wraps around the positioning protrusion, thereby realizing positioning and splicing.

[0052] In some embodiments of this utility model, at least one of the first inner cover 100, the second inner cover 200, and the third inner cover 500 has a relief groove 800 at its bottom. (Refer to...) Figure 8 The clearance groove 800 can avoid protruding structures inside the smart safety helmet, such as the helmet liner support point and ventilation ribs 920, to prevent structural interference between the bracket and the helmet body. It also plays a certain role in positioning the bracket during installation.

[0053] Reference Figure 6In some embodiments of this utility model, the second electronic component mounting structure includes a limiting protrusion 210 disposed on the outer wall of the second inner cover 200. One end of the limiting protrusion 210 away from the second inner cover 200 has a limiting protrusion 211 protruding from the side of the limiting protrusion 210. The limiting protrusion 210 laterally limits the electronic component, preventing lateral displacement of the component; the limiting protrusion 211 forms an axial barrier for the component, preventing it from falling off the outside of the limiting protrusion 210. In this embodiment, a battery 201 is mounted on the second inner cover 200.

[0054] Reference Figure 6 In some embodiments of this utility model, the first inner cover 100 is provided with one or more of the following: a charging port, an indicator light hole, a button hole, and a speaker hole. The main control board 101 is mounted on the first inner cover 100. The first electronic component mounting structure consists of a stud 110 with threaded holes and a positioning post 120. The end of the positioning post 120 may also have a side protrusion to press down on the main control board 101 after installation. The main control board 101 will have corresponding accessories according to its functions, and the first inner cover 100 will have corresponding charging ports, indicator light holes, button holes, and speaker holes. This allows for the exposed adaptation of corresponding functional components. The charging port facilitates connection to an external charger, allowing charging without disassembling the bracket. A sealing plug can also be installed at the charging port to improve dust prevention. The indicator light hole allows light from the indicator light to pass through, making it easy for users to observe the device's working status. The button hole facilitates user operation of the buttons. The speaker hole allows the speaker sound to be transmitted smoothly, ensuring clear voice broadcasting.

[0055] Reference Figure 6 In a further embodiment of this utility model, the main cable tray 310 has an outer opening, and a reinforcing rib 311 is connected between two opposite sidewalls on the open side of the main cable tray 310. The reinforcing rib 311 and the inner wall of the main cable tray 310 define a cable passage hole. The outer opening of the main cable tray 310 facilitates the quick insertion or removal of the cable harness, improving the efficiency of wiring installation and maintenance. At the same time, the reinforcing rib 311 connecting the opposite sidewalls on the open side can enhance the structural strength of the connecting strip 300. Furthermore, the cable passage hole formed by the reinforcing rib 311 and the inner wall of the cable tray can effectively limit the cable harness. Before it is installed on the safety helmet body 900, the cable harness is effectively limited by the reinforcing rib 311, preventing the cable harness from extending out of the main cable tray 310 and affecting assembly.

[0056] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
