Description

Technical Field

[0001] This utility model relates to the field of search and rescue beacon technology, and in particular to a personal search and rescue beacon device based on multi-network converged communication. Background Technology

[0002] Personal search and rescue beacons are critical emergency equipment in outdoor activities, maritime affairs, and aviation, enabling them to transmit distress signals containing location information via satellite systems when in distress. Traditional search and rescue beacons primarily rely on a single communication network (such as the 406MHz band of the Cospas-Sarsat system), relaying signals to ground stations via low Earth orbit (LEOSAR), medium Earth orbit (MEOSAR), or geostationary orbit (GEOSAR) satellites to ultimately guide rescue efforts. Existing personal search and rescue beacon antenna designs lack optimization; fixed antennas are inconvenient to store, while simple folding structures pose risks of unreliable connections, loosening, or accidental shutdown, affecting continuous signal transmission. Utility Model Content

[0003] To address the shortcomings of the existing technology, the purpose of this utility model is to provide a personal search and rescue beacon device based on multi-network converged communication, which can solve the problems of inconvenient antenna storage, unreliable structure, and impact on continuous signal transmission of personal search and rescue beacon devices.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A personal search and rescue beacon device based on multi-network converged communication includes a housing. A control board and a battery are fixedly installed inside the housing. A rotation hole and a limiting hole are provided on the side of the housing. A limiting plate is fixedly installed inside the housing. A rotating shaft that rotates around its own axis is engaged on the limiting plate. The rotating shaft passes through the rotation hole and extends outside the housing. A communication antenna is fixedly sleeved on one end of the rotating shaft. The communication antenna is located outside the housing. An antenna spring is fixedly installed on the control board. The end of the rotating shaft away from the communication antenna abuts against the antenna spring. A limiting post is fixedly installed inside the housing. The limiting post passes through the limiting hole and extends outside the housing. A limiting groove matching the limiting post is provided on the communication antenna. The limiting groove matches the outer end of the limiting post.

[0006] Preferably, the control board includes a light board, a Beidou positioning board, and a communication board, which are fixed in sequence from top to bottom inside the housing. A lighting lamp is fixedly installed on the front of the housing, and the lighting lamp is electrically connected to the light board. The antenna spring is fixedly installed on the communication board.

[0007] Preferably, there are two sets of limiting holes and limiting posts, with the two limiting holes respectively located on both sides of the rotating hole, and four limiting grooves arranged in a "cross" shape with the rotating shaft as the center.

[0008] Preferably, the rotating shaft has a snap-fit ​​groove, the limiting piece is snapped around the snap-fit ​​groove, and the contact portion between the limiting piece and the snap-fit ​​groove has an arc-shaped structure.

[0009] Preferably, a button is fixedly provided on the outer side of the housing, the button is electrically connected to the control board, and the communication antenna can be fitted to cover the button.

[0014] Preferably, a back clip is fixedly provided on the back of the housing.

[0015] The beneficial effects of this utility model are:

[0016] This utility model's personal search and rescue beacon device based on multi-network converged communication utilizes a locking design between a rotating shaft and a limiting plate. This allows the communication antenna to rotate flexibly around its axis, facilitating storage when not in use to reduce size and improve portability. When deployed, the limiting post precisely matches the limiting groove on the communication antenna, forming a mechanical lock to prevent the antenna from shifting due to vibration or external force, ensuring the stability of the signal transmission direction. Simultaneously, the end of the rotating shaft continuously abuts against the antenna spring on the control board, ensuring reliable electrical connection of the communication antenna at any rotation angle and avoiding communication interruptions caused by poor contact. This integrated design optimizes the device's portability and enhances structural stability and signal transmission continuity in harsh environments, significantly improving the reliability of the personal search and rescue beacon.

[0025] To make the technical problems, technical solutions and beneficial effects of the utility model clearer, the utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0026] The embodiments provided by this utility model are as follows: Figures 1-7 As shown, a personal search and rescue beacon device based on multi-network converged communication includes a housing 10. A control board 20 and a battery 30 are fixedly installed inside the housing 10. A rotation hole 40 and a limiting hole 50 are opened on the side of the housing 10. A limiting piece 60 is fixedly installed inside the housing 10. A rotating shaft 70 that rotates around its own axis is snapped onto the limiting piece 60. The rotating shaft 70 passes through the rotation hole 40 and extends to the outside of the housing 10. A communication antenna 80 is fixedly sleeved at one end of the rotating shaft 70. The communication antenna 80 is located outside the housing 10. An antenna spring 90 is fixedly installed on the control board 20. The end of the rotating shaft 70 away from the communication antenna 80 abuts against the antenna spring 90. A limiting post 100 is fixedly installed inside the housing 10. The limiting post 100 passes through the limiting hole 50 and extends to the outside of the housing 10. A limiting groove 110 that matches the limiting post 100 is opened on the communication antenna 80. The limiting groove 110 matches the outer end of the limiting post 100.

[0027] In non-emergency situations, the communication antenna 80 is rotated via the rotating shaft 70 to a storage position close to the housing 10. At this time, the communication antenna 80 is completely flush with the side of the housing 10, and the overall structure of the device is compact, making it easy for users to carry without hindering daily activities or work. When the user encounters danger (such as falling into water, getting lost, etc.) and needs to send a distress signal, the communication antenna 80 can be manually pulled out from the storage position, causing it to rotate and unfold around the axis of the rotating shaft 70. During the rotation, the limiting groove 110 on the antenna will move relative to the limiting post 100 fixed inside the housing 10. When the communication antenna 80 rotates to a specific working angle (e.g., perpendicular to the housing 10), the outer end of the limiting post 100 will precisely engage with the corresponding limiting groove 110, achieving positioning and... The locking mechanism prevents the communication antenna 80 from swinging back unexpectedly due to its own weight or slight external force, ensuring that it remains stable in the optimal signal transmission posture. At the same time, the end of the rotating shaft 70 away from the communication antenna 80 always remains in contact with the antenna spring 90 on the control board 20. When the communication antenna 80 reaches the correct working position and is locked by the limiting structure, the electrical contact between the antenna spring 90 and the rotating shaft 70 also reaches the optimal state, thus establishing a reliable circuit path for signal transmission. After the circuit is connected, the control board 20 starts to work, integrating positioning information (such as Beidou signals) and identification codes, and continuously transmitting distress signals containing precise location data to the outside world through the deployed communication antenna 80 in a multi-network converged communication mode (such as satellite, AIS, etc.) until rescuers arrive or the battery 30 is exhausted.

[0028] Preferably, the control board 20 includes a light board 21, a Beidou positioning board 22, and a communication board 23, which are fixed in sequence from top to bottom inside the housing 10. A lighting lamp 120 is fixedly installed on the front of the housing 10. The lighting lamp 120 is electrically connected to the light board 21. The antenna spring 90 is fixedly installed on the communication board 23. Through modular design, the lighting, positioning, and communication functions are integrated and coordinated. The control board 20 is clearly divided into a three-layer stacked structure of the light board 21, the Beidou positioning board 22, and the communication board 23, which makes the layout of each functional module clear, does not interfere with each other, and facilitates heat dissipation. The beacon 20 is connected to the light board 21 to provide distress lighting; the Beidou positioning board 22 is responsible for accurately obtaining the coordinates of the distress location; the communication board 23 integrates the AIS module and the DSC module, enabling the beacon to not only send distress information through satellite networks (such as Beidou), but also automatically access the Automatic Identification System (AIS) and broadcast alarms on the VHF channel using Digital Selective Calling (DSC), which greatly improves the probability of being discovered and the speed of search and rescue response in complex environments such as maritime incidents. The antenna spring 90 is set on the communication board 23 to ensure low-loss transmission of high-frequency communication signals.

[0029] Preferably, there are two sets of limiting holes 50 and limiting posts 100. The two limiting holes 50 are respectively set on both sides of the rotating hole 40. There are four limiting grooves 110. The four limiting grooves 110 are arranged in a "cross shape" with the rotating shaft 70 as the center. This design ensures that when the communication antenna 80 rotates 90 degrees or 180 degrees, two limiting posts 100 are simultaneously engaged in the corresponding limiting grooves 110, forming symmetrical force support. This effectively prevents the communication antenna 80 from twisting or shaking due to external forces (such as wind resistance or collisions), ensuring the stability of the communication antenna 80 in the direction of communication and greatly improving the directional communication effect.

[0030] Preferably, the rotating shaft 70 is provided with a locking groove 130, and the limiting piece 60 is locked around the locking groove 130, so that the limiting piece 60 can be locked around it. The contact part between the limiting piece 60 and the locking groove 130 is an arc-shaped structure, which reduces the frictional resistance during rotation and makes the communication antenna 80 rotate more smoothly. At the same time, the arc-shaped contact provides a larger bearing area, making the axial limiting more reliable. This avoids the risk of the rotating shaft 70 moving axially or coming out of the limiting piece 60 after long-term use, and improves the durability of the structure.

[0031] Preferably, a button 140 is fixedly provided on the outside of the housing 10. The button 140 is electrically connected to the control board 20. The communication antenna 80 can cover the button 140. When the communication antenna 80 is rotated to the storage position, it can protect the button 140 like a cover, preventing it from being accidentally activated during carrying or storage, saving power and avoiding false alarms. This integrated design achieves the integration of the functions and protection of the communication antenna 80 and the button 140 without adding extra parts.

[0032] Preferably, an indicator light 150 is fixedly installed on the front of the housing 10. The indicator light 150 is electrically connected to the control board 20. The indicator light 150 can use different colors or flashing patterns to indicate the status of the device, such as whether the power supply is sufficient, whether the positioning is successful, whether the signal is being sent, and whether the distress message has been received. This allows users to understand the search and rescue process and improves the usability and user-friendliness of the device.

[0033] Preferably, a waterproof silicone rubber 160 is fixedly disposed inside the housing 10, and the waterproof silicone rubber 160 is disposed along the edge of the side wall of the housing 10. An anti-impact cotton 170 is fixedly disposed on the battery 30. The waterproof silicone rubber 160 disposed on the edge of the inner wall of the housing 10 effectively prevents rainwater and moisture from entering from the seams of the housing 10, protecting the delicate electronic components inside. The anti-impact cotton 170 disposed on the battery 30 can buffer the vibration of the battery 30 when the device is dropped or impacted, prevent the battery 30 from short-circuiting, leaking or being damaged, and greatly enhance the reliability and safety of the device.

[0034] Preferably, a water-drowning extension line 180 is fixedly installed at the bottom of the housing 10. The water-drowning extension line 180 is electrically connected to the control board 20. When the device falls into the water with a person, the water-drowning extension line 180 becomes conductive upon contact with water, which can automatically trigger the beacon to start working and send distress information containing DSC and AIS signals, thereby improving the timeliness of search and rescue.

[0035] Preferably, a number of reinforcing ribs 190 are fixedly provided on the lower inner wall of the housing 10. The reinforcing ribs 190 are arranged in a crisscross pattern, forming a mesh support structure that can effectively disperse external pressure or impact force, prevent the housing 10 from deforming and squeezing internal components, and significantly improve its structural strength and durability.

[0036] Preferably, a back clip 200 is fixedly provided on the back of the housing 10, which allows the user to easily clip the device to a pocket, backpack strap or life jacket. This not only makes it easy to carry, but also allows the user to quickly access the device in an emergency, avoiding delays in calling for help.

[0037] This utility model's personal search and rescue beacon device based on multi-network converged communication utilizes a snap-fit ​​design between the rotating shaft 70 and the limiting piece 60, allowing the communication antenna 80 to rotate flexibly around its axis. This facilitates storage when not in use, reducing its size and improving portability. When deployed, the limiting post 100 precisely matches the limiting groove 110 on the communication antenna 80, forming a mechanical lock to prevent the antenna from shifting due to vibration or external force, ensuring the stability of the signal transmission direction. Simultaneously, the end of the rotating shaft 70 continuously abuts against the antenna spring piece 90 on the control board 20, ensuring reliable electrical connection of the communication antenna 80 at any rotation angle, avoiding communication interruptions caused by poor contact. This integrated design optimizes the device's portability and enhances its structural stability and signal transmission continuity in harsh environments, significantly improving the reliability of the personal search and rescue beacon.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model shall fall within the protection scope of the present utility model.
