Description

Technical Field

[0001] This utility model relates to the field of head-mounted video recording equipment technology, and in particular to a head-mounted video recording module and its multi-scene connection structure. Background Technology

[0002] In current scenarios such as practical training, surgical demonstrations, corporate training, and remote collaboration, real-time and clear visual communication is crucial for knowledge transfer and skills mastery. Especially in space-constrained training classrooms or high-precision operational demonstrations, every subtle movement of the teacher or demonstrator contains key information. Ensuring that all participants can observe these operational details without any blind spots is a core challenge in improving teaching effectiveness.

[0003] However, existing teaching recording and visual aids still have many limitations in practical applications. Traditional fixed cameras or pan-tilt-zoom (PTZ) devices can provide stable images, but due to limitations in installation location and shooting angle, they often fail to capture the fine movements of the operator's hands or specific perspectives. Moreover, these devices are bulky and have complex wiring, making them unsuitable for mobile teaching. Although some head-mounted camera devices have appeared on the market, most suffer from poor wearing comfort, fatigue during prolonged use, and a simple structure that cannot adapt to different scenarios. Utility Model Content

[0004] One of the objectives of this invention is to provide a head-mounted video recording module that can be worn lightly and securely on the user's head, thereby solving the problems of limited viewing angle, uncomfortable wearing, and inconvenient connection in the prior art, and thus achieving high-quality real-time visual sharing.

[0005] The purpose of this utility model is achieved through the following technical solution: a head-mounted video recording module, including an ear clip and a video recording module, wherein the video recording module includes a main housing, a camera module, a memory card interface, a processor unit and a microphone; The main shell is detachably connected to the ear clip via a snap-fit ​​structure, and the ear clip can be snapped onto the outer edge of one ear. The camera module, mounted on the main housing, is used to capture video image signals; The memory card interface, located on the main housing, is used for pluggable connection of external storage media; The microphone, mounted on the main housing, is used to collect audio signals; The processor unit is located inside the main housing and is electrically connected to the camera module, memory card interface and microphone, respectively.

[0006] Another objective of this utility model is to provide a multi-scenario connection structure for connecting a head-mounted video recording module to an external carrier. It also includes an elastic connecting tube, a plug-in part, a plug-in positioning mechanism, and an elastic pressing mechanism. The plug-in part includes a plug strip, a spring-loaded slot, and a limiting boss. The plug-in positioning mechanism includes a positioning slot, an ear seat, and a silicone sleeve. The elastic pressing mechanism includes a buckle, a plastic sleeve, and a torsion spring. Both ends of the flexible connecting tube are connected to ear clips. The flexible connecting tube is made of flexible materials with high elastic deformation capacity and fatigue resistance. The inner part is an elastic metal core and the outer part is covered with a silicone layer. The inner elastic metal core provides the main clamping and restoring force, and the outer silicone layer provides anti-slip and skin-friendly feel. The plug strip is fixed to the outer top of the ear clip on one side of the elastic connecting tube, the spring-loaded slot is opened on the inner side of the plug strip, and the limiting boss is fixed to the tail end of the outer side of the plug strip. It also includes a plug-in positioning mechanism, which includes a positioning slot, an ear seat, and a silicone sleeve. The positioning slot is opened on the inner side outer wall of the main housing. A positioning frame is also fixed to the inner side outer wall of the main housing. The positioning frame has symmetrical clearance holes in its main body. The ear seat is fixed to the middle of the bottom end of the positioning frame. The silicone sleeve is sleeved and installed on the outer end of the ear seat. The inner side of the main body of the main shell is symmetrically provided with rotating seats. The snap fastener is a symmetrical multi-segment corner structure. The inner ends of the corners on both sides are fixed with rotating shafts, and the two ends of the rotating shafts are respectively screwed into different rotating seats. The inner side of the main body of the main housing is also provided with a positioning groove and a retaining plate. The torsion spring is a double torsion spring structure. Its main body is sleeved on the outer circle surface of the rotating shaft, the middle part is fixed with the retaining plate, and the two ends are respectively fixed on the outer circle surface of the corners of the buckle. The plastic sleeve is fixed to the middle of the straight section of the outer end of the snap fastener and is made of a flexible material with a rough surface. When the user is wearing glasses, this utility model can also connect with the temples of the glasses. Before connecting, the snap fastener needs to be moved to the open position. The width of the positioning slot can match the width of most temples, and the space between the earpiece and the positioning slot is also sufficient to accommodate the insertion of most temples. Meanwhile, in order to ensure that the temple can be inserted into the positioning slot and the ear base without wobbling, a spare silicone sleeve can be fitted onto the outer end of the ear base. The inner wall thickness of the silicone sleeve is greater than the outer wall thickness. By flipping the silicone sleeve, either the inner or outer side of the silicone sleeve can be aligned with the positioning slot. Furthermore, since the silicone sleeve can deform when squeezed, it can improve its fit to the temple. After installing the recording module in the appropriate position at the front of the temple, release the buckle. This allows the inner side of the plastic sleeve to press against the inner side of the temple under the elastic torque of the torsion spring. Combined with the use of a silicone sleeve, this improves the security of the connection between the recording module and the temple.

[0007] By adopting the above technical solution, this utility model can achieve the following beneficial effects: (1) By setting up an adaptable assembly system including positioning slots, ear seats and elastic pressing mechanism, this utility model significantly improves the scene adaptability and connection reliability of the device; the structure not only uses the guide to achieve quick and accurate alignment of the video module and the plug-in part, but also ensures the firmness of the connection through the snap fastener driven by the torsion spring and the snap-fit ​​of the spring-pressing slot; especially when used with glasses, the flip-out design and thickness difference of the silicone sleeve can flexibly fill the gap of the temples and eliminate shaking, so that the same device can be firmly worn on both ears through the elastic connecting tube and ear clip, and can also be seamlessly compatible with the temples of glasses, greatly expanding the scope of use of the product; (2) This utility model effectively solves the problem of insufficient support or discomfort of traditional single-material connectors by adopting a composite structure elastic connecting tube with an internal elastic metal core and an external flexible layer. The structure utilizes the internal core to provide strong elastic recovery force to ensure that a specific curvature is maintained in the natural state. When the ear clips at both ends open to adapt to the head width, they can generate continuous clamping potential energy to prevent the device from shaking and falling off. At the same time, the external covering layer provides excellent anti-slip performance and skin-friendly touch, avoiding the cold feeling caused by direct contact of metal with the skin, and achieving a perfect balance between high stability and high comfort.

[0013] like Figures 1-9 As shown, a head-mounted video recording module and its multi-scene connection structure are disclosed. The main housing 401 of the video recording module 4 is detachably connected to the ear clip 1 through a buckle structure. The ear clip 1 can be snapped onto the outer contour of one ear. The camera module 404 is mounted on the main housing 401 and is used to acquire video image signals. The camera module 404 uses a high-definition wide-angle lens to ensure that the shooting range is large enough and the image is clear. The memory card interface 405 is disposed on the main housing 401 and is used for pluggable connection of external storage media. The memory card interface 405 is connected to the data bus of the processor unit 409 via the SDIO bus or the SPI bus. Microphone 411, mounted on the main housing 401, is used to collect audio signals, facilitating simultaneous recording during user explanations; The processor unit 409 is located inside the main housing 401 and is electrically connected to the camera module 404, the memory card interface 405 and the microphone 411 respectively. The cover 402 is fixedly connected to the main housing 401, and the cover 403 is disposed in the main body of the cover 402, with the camera module 404 located inside the cover 403; The main housing 401 is also provided with a power switch 406 and a reset button 407, both of which are electrically connected to the processor unit 409. The charging interface 408 is located on the main housing 401 and is used to connect to an external power source and charge the lithium battery 410. The lithium battery 410 is located inside the main housing 401 and has a battery life of at least 2 hours. Furthermore, both the charging port 408 and the lithium battery 410 are electrically connected to the processor unit 409 to provide power to the head-mounted video recording module. The camera module 404 is connected to the data bus of the processor unit 409 via a MIPI interface or a DVP interface, and the charging interface 408 is a Type-C interface or a Micro-USB interface. The processor unit 409 is also connected to a wireless connectivity module that supports Wi-Fi or Bluetooth for real-time transmission of video and audio signals.

[0014] The multi-scenario connection structure, consisting of the flexible connecting tube 2, the insertion part 3, the insertion positioning mechanism 5, and the flexible pressing mechanism 6, is as follows: Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown; Both ends of the elastic connecting tube 2 are connected to ear clips 1. The elastic connecting tube 2 is made of flexible material with high elastic deformation capacity and fatigue resistance. The inner part is an elastic metal core and the outer part is covered with a silicone layer. The inner elastic metal core provides the main clamping and restoring force, and the outer silicone layer provides anti-slip and skin-friendly feel. The internal metal core of the flexible connecting tube 2 is made of nickel-titanium shape memory alloy or beryllium copper alloy, such as the 0.7mm flexible titanium wire used in the headphone hook; The elastic connecting tube 2 can utilize its own elastic restoring force to tend to maintain a specific curvature or spacing in a natural state. When the user wears it, the ear clips 1 at both ends are forced to open or close to adapt to different head widths. At this time, the elastic connecting tube 2 deforms and generates accumulated elastic potential energy, which is converted into a continuous clamping force on the head, ensuring that the structure is firmly fixed between the ears and preventing it from falling off due to head shaking. The plug strip 301 in the plug part 3 is fixed to the outer top of the ear clip 1 on one side of the elastic connecting tube 2, the spring-loaded groove 302 is opened on the inner side of the plug strip 301, and the limiting boss 303 is fixed to the tail end of the outer side of the plug strip 301. The positioning slot 501 in the insertion positioning mechanism 5 is opened on the outer wall of the inner side of the main housing 401. The outer wall of the inner side of the main housing 401 is also fixedly connected to the positioning frame 502. The positioning frame 502 has symmetrically opened clearance holes 504 in its main body. The ear seat 503 is fixedly connected to the middle of the bottom end of the positioning frame 502. The silicone sleeve 505 is fitted onto the outer end of the earpiece 503; When the video recording module 4 is assembled with the plug strip 301 on the top of the ear clip 1, the positioning slot 501 and the ear seat 503 can provide positioning guidance for the plug strip 301 to be inserted, so that the plug strip 301 forms a positioning insertion engagement with the main housing 401 along the guidance of the positioning slot 501 and the ear seat 503. The rotating base 604 in the elastic pressing mechanism 6 is symmetrically arranged in the inner side body of the main housing 401. The pressing buckle 601 is a symmetrical multi-segment corner structure. The inner ends of the two corners are fixed with rotating shafts 603. The two shaft ends of the rotating shafts 603 are respectively screwed into different rotating bases 604. The clearance hole 504 is used to provide space for the snap fastener 601 to open and close; The inner side of the main body of the main housing 401 is also provided with a positioning groove 605 and a retaining plate 606. The torsion spring 607 is a double torsion spring structure. Its main body is sleeved on the outer circular surface of the rotating shaft 603, the middle part is fixed with the retaining plate 606, and the two ends are respectively fixed on the outer circular surface of the corners of the buckle 601. It can provide a stable and safe elastic torque for the buckle 601 and the rotating shaft 603 while simplifying the structure. The plastic sleeve 602 is fixed to the middle of the straight section of the outer end of the snap fastener 601, and is made of a flexible material with a rough surface. Specifically, the plastic sleeve 602 is injection molded from thermoplastic polyurethane elastomer (TPU) or soft polyvinyl chloride (Soft PVC), and its rough outer surface is integrally injection molded through a mold cavity with a preset texture on the surface during injection molding. When the snap fastener 601 is moved to the open state, the movable plug bar 301 can be guided along the positioning slot 501 and the ear seat 503 to form a positioning plug-in engagement with the main housing 401 until the limiting boss 303 at the end of the plug bar 301 is in contact with the side of the main housing 401. When the snap fastener 601 is released, the plastic sleeve 602 can be just inserted into the spring-loaded slot 302, so that the recording module 4 and the plug part 3 form a safe and stable connection. When the user is wearing glasses 7, this utility model can also connect to the temples of glasses 7; before connection, the snap fastener 601 needs to be moved to the open position; The opening width of the positioning slot 501 can match the width of most temples, and the space between the earpiece 503 and the positioning slot 501 is also sufficient to accommodate the insertion of most temples. Meanwhile, in order to ensure that the temple can be inserted between the positioning slot 501 and the ear base 503 without wobbling, a spare silicone sleeve 505 can be fitted onto the outer end of the ear base 503. The inner wall thickness of the silicone sleeve 505 is greater than the outer wall thickness. By flipping the silicone sleeve 505, either the inner or outer side of the silicone sleeve 505 can be aligned with the positioning slot 501. Furthermore, since the silicone sleeve 505 can deform when squeezed, its adaptability to the temple can be improved. After installing the video recording module 4 in the appropriate position at the front end of the temple, release the buckle 601 from its open state. Under the elastic torque of the torsion spring 607, the inner side of the plastic sleeve 602 will press against the inner side of the temple. With the use of the silicone sleeve 505, the safety of the connection between the video recording module 4 and the temple can be improved.

[0015] The working principle is as follows: When the elastic connecting tube 2 is worn independently, the video recording module 4 can be connected to the plug-in part 3. Utilizing the high elasticity of the elastic metal core inside the elastic connecting tube 2, the ear clips 1 at both ends of the elastic connecting tube 2 generate an inward pre-tightening force. Regardless of the user's head circumference, the elastic connecting tube 2 can automatically adapt through deformation to ensure continuous clamping force and prevent the device from slipping. To connect this utility model to the temple of the eyeglasses, the operator first needs to rotate the buckle 601 to open it against the torque of the torsion spring 607. At this time, the temple is aligned with the positioning slot 501 on the outer wall of the inner side of the main housing 401, so that the temple enters the channel formed by the positioning slot 501 and the ear seat 503. The thickness is adjusted by flipping the silicone sleeve 505. The wall thickness difference and elastic deformation of the silicone sleeve 505 are used to tightly fit the temples of different thicknesses and eliminate the wobbling gap. When the recording module 4 is moved to the appropriate position in the temple, the buckle 601 is released, the torsion spring 607 releases the stored elastic potential energy, drives the inner side of the plastic sleeve 602 to form a pressing and abutting contact with the inner side of the temple, and works together with the insertion and positioning mechanism 5 to achieve a safe, stable and shockproof mechanical connection between the recording module 4 and the temple. Data acquisition and processing: The video stream acquired by the camera module 404 is transmitted to the processor unit 409 through the MIPI / DVP interface, and the audio is synchronously input by the microphone 411. Storage and transmission: The processor unit 409 encodes and compresses audio and video data. On the one hand, it writes the data to the memory card in the memory card interface 405 via the SDIO / SPI bus for local recording; on the other hand, it transmits the data in real time to a mobile device for preview or live streaming via the integrated Wi-Fi or Bluetooth wireless module. Power supply management: The lithium battery 410 is charged through the charging interface 408, and the power management system supplies power to all components of the machine. The power switch 406 controls the on / off state, and the reset button 407 is used for forced restart in case of system abnormality.

[0016] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model 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.
