Description

Technical Field

[0001] This application relates to the field of headband technology, and in particular to a smart headband. Background Technology

[0002] In modern work settings, there is an increasing demand for information recording and communication, especially in specialized environments such as construction and industrial production. A smart headband is a device used on construction sites to record the construction process while simultaneously providing lighting and video recording.

[0003] However, in some environments, safety regulations require workers to wear hard hats to protect their heads. This leads to an irreconcilable contradiction: workers cannot wear a conventional smart headband while wearing a hard hat. Currently, elastic bands are typically used to attach the headband to the hard hat.

[0004] However, the straps are not stable enough. When the user is active, such as walking or exercising, the headband is prone to shaking, shifting or even falling off, which affects the normal use of the equipment and reduces its reliability and stability. Utility Model Content

[0005] This application provides a smart headband to solve the problem that current headbands are difficult to securely attach to safety helmets.

[0006] A smart headband, comprising:

[0007] The headband body is ring-shaped and includes a camera component, a voice component, a control component, and a power module. The camera component and the power module are located at the front and rear ends of the headband body along its length. The headband body has three locking parts that are spaced apart and extend downwards, each of which is fixed to the safety helmet.

[0008] By adopting the above technical solution, a three-point fixation is formed between the helmet and the three spaced-apart locking parts, creating a stable triangular support structure. This method can greatly resist swaying and impact from different directions, ensuring that the headband will not loosen or shift when the worker moves or their head shakes, thus guaranteeing the stability of the camera module's field of view and the reliability of the data. The power module is located at the rear, which can effectively balance the weight of the camera module located at the front, forming a scientifically designed weight distribution structure. This significantly reduces the burden on the user's neck, avoiding discomfort caused by a "top-heavy" feeling, thereby improving comfort during long-term wear.

[0009] In one embodiment, two of the latching parts are buckles, which are disposed opposite to each other on both sides of the headband body along the width direction, and the buckles can fasten the left and right sides of the safety helmet; the other latching part is a slot, which is disposed at the lower end of the power module, and the slot can fasten the rear edge of the safety helmet.

[0010] By adopting the above technical solution, the buckles on both sides provide clamping force in the left and right directions to prevent the headband from swaying horizontally; the slot on the rear side uses the rear edge of the helmet to limit the movement of the headband, effectively preventing it from moving back and forth. This multi-dimensional limiting method further enhances stability.

[0011] In one embodiment, the end of the buckle near the helmet is hook-shaped and has an anti-slip pad.

[0012] By adopting the above technical solution, the anti-slip pad increases the coefficient of friction between the buckle and the helmet surface. The combination of the hook structure and the anti-slip pad provides dual protection of mechanical locking and friction locking, greatly improving the reliability of the connection and ensuring that the headband remains firmly fixed to the helmet under harsh working conditions such as violent movement or accidental collisions.

[0013] In one embodiment, the camera assembly includes a first housing, a camera, a light assembly, and a lens. The first housing is located at the front end of the headband body along its length. The camera and the light assembly are located inside the first housing and protrude from the first housing along its length. The lens is fixed to the first housing and covers the camera and the light assembly. A sealing ring is provided between the first housing and the headband body.

[0014] By adopting the above technical solution, the camera, light assembly, and lens are integrated into the first housing, protecting the internal components while optimizing the spatial layout and reducing the headband's volume. The light assembly provides auxiliary lighting, improving the camera's shooting quality in low-light environments, making it suitable for nighttime operations or indoor scenes with insufficient light. The lens covers the camera and light assembly, preventing dust, water mist, or external force damage, extending their service life. The sealing ring forms a seal between the first housing and the headband body, allowing normal use in humid or dusty environments (such as outdoor operations in rainy weather or coal mining).

[0015] In one embodiment, the voice component includes a second housing and a voice module. The second housing is fixed to the headband body, and the voice module is disposed inside the second housing. The voice module is electrically connected to the control component and includes a speaker. The second housing has a sound outlet, and the speaker corresponds to the sound outlet. A dustproof mesh is provided at the sound outlet.

[0016] By adopting the above technical solution, the voice module collects sound through a microphone and, in conjunction with the control components, enables voice command recognition (such as "start recording" or "take a photo"). The speaker amplifies sound through a sound outlet, supporting two-way communication or voice prompts (such as danger warnings or operating instructions). The addition of a dustproof mesh effectively prevents industrial dust from clogging the speaker, ensuring audio quality and the long-term reliability of the components.

[0017] In one embodiment, the control component includes a main control board, a button module, and a heat sink. The main control board is disposed between the headband body and the camera component. The button module is disposed on the other side of the headband body along the width direction and opposite to the voice component. The button module is electrically connected to the main control board. The heat sink is disposed between the headband body and the main control board.

[0018] By adopting the above technical solution, the button module and voice component are positioned opposite each other, allowing users to operate with one hand (such as power on / off and function switching), which conforms to ergonomic design. The main control board is located between the headband body and the camera component, shortening the signal transmission distance, reducing interference, and improving system stability. The addition of heat sinks effectively reduces the temperature of core heat-generating components such as the main control board and camera, preventing performance degradation or component damage due to overheating, thereby ensuring stable system operation and extending product lifespan.

[0019] In one embodiment, the button module includes a third housing, a button board, and an FPC circuit board. The third housing is fixed to the headband body. The button board and the FPC circuit board are disposed inside the third housing. The button board has a plurality of buttons protruding from the third housing. The FPC circuit board is electrically connected to the main control board. The button board also has a charging board, on which a vibration motor is mounted.

[0020] By employing the above technical solution, pressing different buttons can achieve multiple functions. In noisy industrial environments, relying solely on speaker alerts may be masked by ambient noise. Adding a vibration motor allows the system to send notifications, warnings, or operational feedback to users through tactile vibration, while also reminding personnel to press buttons promptly.

[0021] In one embodiment, the headband body further includes a protrusion located at the lower end of the button module, and a sensing module electrically connected to the main control board is disposed within the protrusion.

[0022] By adopting the above technical solution, the protruding part is ergonomically designed, providing a clear physical positioning point during wear. This helps users quickly and accurately place the headband in the correct position by touch, improving ease of use. The sensing module can automatically detect whether the headband is being worn. This can trigger various intelligent functions, such as: when the user removes the headband, the system automatically goes into sleep mode or turns off the screen to save power; when the user puts on the headband, the system automatically wakes up, achieving more intelligent human-computer interaction and effective power management.

[0023] In one embodiment, the power module includes a battery casing and a battery, the battery casing covering the battery, and the battery casing being made of PC or TC material.

[0024] By adopting the above technical solutions, the battery casing made of these materials can achieve good heat dissipation and a robust effect.

[0025] In one embodiment, the battery casing is filled with thermally conductive adhesive, which wraps around the battery.

[0026] By adopting the above technical solution, on the one hand, the thermally conductive adhesive can quickly conduct the heat generated by the battery to the battery casing, effectively dissipating heat and preventing the battery from overheating and causing safety hazards. On the other hand, the cured thermally conductive adhesive firmly encapsulates the battery inside the battery casing, providing excellent impact and vibration resistance, effectively preventing the risk of internal short circuits caused by violent movement or accidental drops, and further improving the safety and reliability of the power module.

[0027] In summary, this application includes at least one beneficial effect:

[0028] 1. A three-point fixation system, consisting of three spaced-apart snap-fit ​​points, forms a stable triangular support structure with the safety helmet. This method effectively resists swaying and impacts from different directions, ensuring the headband remains secure and doesn't loosen or shift when the worker moves or their head shakes, thus guaranteeing the stability of the camera module's field of view and the reliability of the data. The power module is located at the rear, effectively balancing the weight of the front-mounted camera module, creating a scientifically designed weight distribution structure. This significantly reduces the burden on the user's neck, preventing discomfort caused by a "top-heavy" feeling and improving comfort during extended wear.

[0029] 2. Pressing different buttons can perform multiple functions. In noisy industrial environments, relying solely on speaker alerts may be masked by ambient noise. Adding a vibration motor allows the system to send notifications, warnings, or operational feedback to users through tactile vibration, while also reminding personnel to press buttons promptly.

[0030] 3. On the one hand, the thermally conductive adhesive can quickly conduct the heat generated by the battery to the battery casing, effectively dissipating heat and preventing the battery from overheating and causing safety hazards. On the other hand, the cured thermally conductive adhesive firmly encapsulates the battery inside the battery casing, providing excellent impact and vibration resistance, effectively preventing the risk of internal short circuits caused by violent movement or accidental drops, further improving the safety and reliability of the power module.

Detailed Implementation

[0036] The following is in conjunction with the appendix Figure 1-4 The smart headband provided in this application will be described in further detail.

[0037] Example 1

[0038] Please see Figure 1-4 The smart headband provided in this application embodiment includes a headband body 1, a camera component 2, a voice component 3, a control component 4, and a power module 7.

[0039] like Figures 1 to 2As shown, specifically, the headband body 1 is ring-shaped and made of ABS material. This material has good strength and toughness, ensuring that the headband body 1 is not easily damaged during daily use, while also being lightweight and not adding too much burden to the workers. The headband body 1 includes a camera component 2, a voice component 3, a control component 4, and a power module 7. The camera component 2 and the power module 7 are located at the front and rear ends of the headband body 1 along its length. The headband body 1 has three locking parts 11, which are spaced apart and extend downwards, all of which are fixed to the safety helmet. This three-point fixing method makes the connection between the headband and the safety helmet more stable, preventing the headband from shaking, shifting, or even falling off during user activities, ensuring the normal use of the equipment, and improving the reliability and stability of use. In this embodiment, two locking parts 11 are buckles, which are located opposite each other on both sides of the headband body 1 along its width. The end of the buckle near the safety helmet is hook-shaped and has an anti-slip pad. The anti-slip pad is made of rubber, which increases the friction between the buckle and the helmet, preventing the headband from coming off. The buckle can fasten the left and right sides of the helmet, and the hook-like structure and anti-slip pad ensure a stable connection. Another locking part 11 is a slot, located at the lower end of the power module 7. The slot can lock the rear edge of the helmet, further enhancing the connection stability between the headband and the helmet. The headband body 1 can be coated with a waterproof and breathable membrane to improve its waterproof and breathable properties. The headband body 1 is located along the width direction (near the ears) and along the length direction (facing the face).

[0040] The camera assembly 2 is located at the front end of the headband body 1 along its length and is capable of capturing images. Specifically, it includes a first housing 21, a camera 22, a light assembly 23, and a lens 24. The first housing 21 is fixed to the headband body 1 and has internal space to accommodate the camera 22 and the light assembly 23. The camera 22 and the light assembly 23 are located inside the first housing 21 and protrude from the front end for easy shooting or illumination. The first housing 21 can also be made of ABS material to protect the internal camera 22 and light assembly 23. Its shape is adapted to the front end of the headband body 1 and is usually streamlined, which is both aesthetically pleasing and reduces wind resistance. A sealing ring 5 is provided between the first housing 21 and the headband body 1. The sealing ring 5 is generally made of rubber and is annular. Its function is to prevent dust, moisture, etc. from entering the interior of the first housing 21 and affecting the normal operation of the camera assembly 2. In addition to the rubber sealing ring 5, a silicone sealing ring 5 can also be used, as silicone sealing ring 5 has better high temperature resistance and aging resistance. The camera 22 is a high-definition camera 22, capable of capturing clear images and videos. Its pixel count is generally high, meeting the image quality requirements of various working scenarios. The lamp assembly 23 typically includes a laser lamp and a small illumination board. The illumination board has advantages such as low energy consumption, high brightness, and long lifespan. In low-light environments, the lamp assembly 23 can provide illumination for the camera 22, ensuring shooting quality. The lens 24 is generally made of transparent optical glass, possessing good light transmission and scratch resistance, protecting the camera 22 lens without affecting image clarity. Besides optical glass lenses 24, acrylic lenses 24 can also be used, as they are lighter and less expensive.

[0041] The voice component 3 is located on one side of the headband body 1 along its width and is capable of recording and making calls. Specifically, it includes a second outer shell 31 and a voice module 32. The second outer shell 31 is generally made of ABS and is fixed to the headband body 1. Its shape is ergonomically designed for easy wearing and does not affect the normal activities of the staff. The voice module 32 includes a speaker 321, which can play the other party's voice information. The voice module 32 is also equipped with a microphone for recording and sending voice information. The second outer shell 31 has sound outlet holes 311, which are small circular holes concentrated on the outside of the speaker 321. A dustproof mesh can also be installed at the sound outlet holes 311 to prevent dust blockage and ensure that the sound can be clearly transmitted. In addition to the circular sound outlet holes 311, a strip-shaped sound outlet hole 311 can also be used, although the acoustic effect of the strip-shaped sound outlet hole 311 may be different. Through the voice module 32, the staff can easily conduct voice communication and record information. The second outer shell 31 can also contain a positioning module 6, such as a GPS antenna, for real-time positioning.

[0042] The control component 4 is located on the headband body 1 and electrically connected to the camera component 2 and the voice component 3. It can communicate with the cloud platform and control the camera component 2 and the voice component 3. Specifically, it includes a main control board 41 and a button module 42. The main control board 41 is a PCBA board that integrates various electronic components and chips, such as a SIM card board and a 5G high-speed communication chip, to achieve network connectivity and transmit environmental information to the cloud platform in real time. The cloud platform then stores and analyzes the collected data. When a hazard is detected, the cloud platform controls the main control board 41 to operate the camera component 2 or the voice component 3. Relevant personnel can also communicate with on-site workers via video call at any time, minimizing and preventing potential safety hazards. The control component 4 may also include a heat sink 43, which is located between the headband body 1 and the main control board 41. In this embodiment, the camera 22 and the light component 23 are both located on the main control board 41, and the heat sink 43 is a heat-dissipating hardware that is attached to the main control board 41 to dissipate heat. Heat dissipation hardware refers to metal components used in heat dissipation systems. They are typically made of metals with good thermal conductivity, such as aluminum and copper. Their main function is to transfer heat from the heat source to the surrounding environment through conduction, convection, and radiation, thereby reducing the operating temperature of the equipment. The main control board 41 is also electrically connected to the positioning module 6. At regular intervals, the main control board 41 sends real-time location information to the backend system, facilitating enhanced on-site personnel management, categorizing and statistically analyzing information on company personnel and external personnel entering and leaving the production area, and accurately displaying the dynamic status of online personnel within the production area.

[0043] like Figure 3As shown, the button module 42 is located on the other side of the headband body 1 along the width direction and opposite to the voice component 3. The button module 42 can be composed of a third housing 421, a button board 422, and an FPC circuit board 423. The third housing 421 is fixed to the headband body 1. The button board 422 and the FPC circuit board 423 are located inside the third housing 421. The button board 422 has multiple silicone buttons that protrude from the third housing 421. The FPC circuit board 423 is electrically connected to the main control board 41. The operator can control the camera component 2 to turn on / off, take photos, record videos, etc., and the voice component 3 to make calls, record audio, etc. by pressing the buttons. The button board 422 is also provided with a charging plate 4221 on the side near the headband body 1. A vibration motor can be installed on the charging plate 4221. The vibration motor can send notifications, warnings, or operation feedback to the user through vibration. The headband body 1 also includes a protrusion 12, located at the lower end of the button module 42. A sensing module 121 is housed within the protrusion 12 and is electrically connected to the main control board 41. The protrusion 12 facilitates user confirmation of correct helmet wearing. The sensing module 121 is typically an infrared sensor capable of detecting whether the worker is wearing a safety helmet. When the helmet is detected, the control component 4 automatically activates the corresponding component, improving ease of use. Besides infrared sensors, pressure sensors can also be used. Alternatively, the sensing module 121 can be any other sensor capable of monitoring personnel movement, determining their current state. The management center can then analyze the personnel's movement status to determine if an accident has occurred and take timely action. In this embodiment, there are five buttons arranged in a W shape. Each button has a different function when pressed from top to bottom and then from top to bottom: the first button is short-pressed to record locally, and long-pressed to power on / off; the second button is short-pressed to adjust the volume, and long-pressed to turn the light on / off; the third button is short-pressed to take a photo, and long-pressed to turn on the laser light; the fourth button is short-pressed to reset the volume, long-pressed to record voice, and released to send; the fifth button is short-pressed to send an SOS signal for a video call, and long-pressed to check the battery level (network status). Furthermore, these operations can also be performed directly by voice control on the main control board 41, freeing up hands to focus on high-risk operations and reducing the risk of misoperation.

[0044] like Figure 4As shown, the smart headband also includes a power module 7, which is located at the rear end of the headband body 1 along its length and provides power to the camera component 2, voice component 3, and control component 4. The power module 7 includes a battery housing 71 and a battery 72. The battery housing 71 covers the battery 72 and is fixed to the headband body 1. The battery housing 71 is made of PC or TC materials; PC material has high strength and good transparency, while TC material has better heat dissipation performance. The battery 72 is generally a lithium battery, which has advantages such as high energy density, light weight, and fast charging speed. Its capacity can be selected according to actual needs to ensure that the smart headband can work continuously for a long time. Besides lithium batteries, lead-acid batteries can also be used, but lead-acid batteries are heavier and not suitable for prolonged wear.

[0045] The outer surface of the battery casing 71 can also be integrated with heat dissipation fins. These fins greatly increase the contact area between the battery casing 71 and the air, efficiently dissipating heat through natural convection. The battery casing 71 is also filled with thermally conductive adhesive, which encases the battery 72. The thermally conductive adhesive conducts the heat generated by the battery 72 to the battery casing 71, accelerating heat dissipation and ensuring the safety and stability of the battery 72. Furthermore, the cured thermally conductive adhesive forms a robust yet flexible whole with the battery casing 71, securing the battery 72 and providing vibration and impact resistance, effectively preventing the risk of internal short circuits caused by violent movement.

[0046] The implementation principle of this embodiment is as follows: The smart headband integrates functions such as camera, voice, and control, and is fixed to the safety helmet through a three-point snap-fit ​​connection of the snap-fit ​​part 11. This improves the stability of the connection between the headband and the safety helmet, preventing the headband from shaking, shifting, or even falling off during use, thus ensuring the normal operation of the device. The control component 4 coordinates the work of all components, realizing information integration and unified control, meeting the needs of modern work for efficient information interaction and comprehensive management. At the same time, the reasonable layout and design of each component improves the convenience and stability of use, reduces the burden on workers, and improves work efficiency.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
