Description

Technical Field

[0001] This utility model relates to the field of lifesaving, and in particular to the positioning alarm of lifebuoys. Background Technology

[0002] To protect the safety of lifeguards, lifebuoys are usually equipped with location alarms. While lifebuoys can be made into smart lifebuoys, current smart lifebuoys have the following problems when used: Considering the battery capacity of lifebuoys, the existing lifebuoy positioning and alarm functions are normally off, only activating when the life-saving switch is triggered. However, if the trigger switch is made easy to activate, it can easily be accidentally triggered during daily use; if the trigger switch is made concealed and difficult to operate accidentally, it will be difficult for users or rescuers to automatically activate the lifebuoy's positioning and alarm functions in an emergency, and even if activated, the positioning and alarm functions may be accidentally deactivated by debris impacting the water.

[0003] Therefore, there is an urgent need for a positioning alarm device and a smart lifebuoy that can solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a positioning alarm for a smart lifebuoy and a smart lifebuoy that is not easily misoperated and can be easily opened in an emergency, making it safe and reliable to use.

[0005] To achieve the above objectives, this utility model provides a positioning alarm device for an intelligent lifebuoy, comprising a housing, a positioning alarm module installed within the housing, a magnetic switch, and a magnetic trigger. The housing has a trigger groove for accommodating the magnetic trigger. Inside the housing, at a position corresponding to the bottom of the trigger groove, a metal part is provided that magnetically engages with the magnetic trigger. The sensing element of the magnetic switch is located inside the housing and near the bottom of the trigger groove to sense the magnetic field within the trigger groove. The magnetic switch is connected to the positioning alarm module and is used to control the opening and closing of the positioning alarm module. The magnetic switch is a normally closed switch, so that the positioning alarm module is closed when a magnetic field is sensed and opened when no magnetic field is sensed.

[0006] Preferably, a drain outlet is provided on the wall of the trigger groove, extending from the top to the bottom of the groove wall and penetrating the groove wall. This prevents water from accumulating in the trigger groove and facilitates the removal of the magnetic triggering part from the trigger groove.

[0007] Specifically, there are multiple drain outlets, which are located on at least two opposite sides of the trigger slot.

[0008] Preferably, the positioning alarm module includes a positioning unit, an alarm unit, and an energy storage unit, wherein the alarm unit includes one or more combinations of a light alarm and a signal alarm.

[0009] Specifically, the positioning alarm for the smart lifebuoy also includes a photovoltaic panel, which is located on the outside of the housing and converts solar energy into electrical energy. The energy storage unit is connected to the photovoltaic panel to receive and store the electrical energy converted by the photovoltaic panel.

[0010] More specifically, the trigger slot is located at the top of the housing, and there are two photovoltaic panels, which are respectively located on two opposite sides of the top.

[0011] Specifically, the housing is also provided with a charging interface, which is connected to the energy storage battery to deliver external electrical energy to the energy storage battery. The charging interface can be a wired charging interface or a wireless charging interface. When it is a wired charging interface, the housing has an opening for inserting a charging head into the wired charging interface, and the opening is also provided with a removable sealing plug to prevent water from entering the housing.

[0012] Preferably, a clearance groove is formed on the metal part, and the sensing element of the magnetic switch is accommodated in the clearance groove, so that the metal part can effectively magnetically attract and position the magnetic trigger part, while the magnetic switch can quickly sense the magnetic trigger part.

[0013] Preferably, the magnetic trigger has a rope connection portion for connecting a rope. In use, simply securing the rope and removing the smart lifebuoy, or pinching the rope to remove the magnetic trigger, quickly activates the positioning alarm module, making it suitable for operation in fast-paced environments.

[0014] This utility model also provides an intelligent lifebuoy, including a lifebuoy body and a positioning alarm. The positioning alarm is a positioning alarm for an intelligent lifebuoy as described above. The positioning alarm is installed on the lifebuoy body, and the magnetic switch is exposed on the outer side of the housing away from the lifebuoy body.

[0015] Preferably, the lifebuoy body has a mounting groove on its side wall, the positioning alarm is embedded in the mounting groove, and the magnetic switch is exposed on the outer side of the housing away from the lifebuoy body. The positioning alarm is engaged with the mounting groove or threadedly fixed.

[0016] Preferably, the positioning alarm is connected to two opposite sides by connecting straps, and the ends of the two connecting straps are provided with interlocking buckles. The two connecting straps pass around the lifebuoy body and are connected by the plug-in buckles, so that the positioning alarm and the lifebuoy body are tied together by the connecting straps.

[0017] Compared with existing technologies, this invention uses the magnetic attraction between a magnetic switch and a magnetic trigger to open / close the positioning alarm module. When the smart lifebuoy is idle or in its designated placement position, simply place the magnetic trigger on the trigger slot. The magnetic trigger will then adhere to the bottom of the slot, and the magnetic switch will sense the magnetic field of the trigger to close the positioning alarm module. Because the magnetic trigger is positioned by the trigger slot, it is less likely to be accidentally triggered. When the smart lifebuoy is to be used, simply remove the magnetic trigger from the trigger slot. The magnetic switch will no longer sense the magnetic field of the trigger and will then open the positioning alarm module. This allows operators to quickly open the positioning alarm module in emergencies. Furthermore, the magnetic trigger is separate from the housing containing the positioning alarm module during use, preventing accidental closure of the alarm module and ensuring safe and reliable operation.

[0041] refer to Figures 4 to 6 In this embodiment, a smart lifebuoy is also disclosed. The smart lifebuoy includes a lifebuoy body 10 and a positioning alarm 20. The positioning alarm 20 is mounted on the lifebuoy body 10, and the magnetic control switch 241 is exposed on the outer side of the housing 21 away from the lifebuoy body 10. In this embodiment, a mounting groove 11 is recessed on the outer side of the lifebuoy body 10 away from its center. The positioning alarm 20 is embedded in the mounting groove 11, and the magnetic control switch 241 is exposed on the outer side of the housing 21 away from the lifebuoy body 10.

[0042] refer to Figure 4 and Figure 5The mounting groove 11 includes two groove walls 111 and a groove bottom 112 located between the two groove walls 111. The two groove walls 111 are arranged opposite each other circumferentially along the life ring body 10, forming a three-sided opening between the two groove walls 111. The opening includes an upward-facing upper opening and two opposing lateral openings arranged axially along the life ring body 10. The housing 21 matches the shape of the mounting groove 11 and is embedded in the mounting groove 11. The edge of the lateral opening is formed by the edge of the two groove walls 111 and the edge of the groove bottom 112, that is, the mounting groove 11 has only two groove walls 111, and there are no other groove walls between the two groove walls 111. The mounting groove 11, viewed axially, is a U-shaped through groove.

[0043] refer to Figure 5 and Figure 6 The positioning alarm 20 is engaged with the mounting slot 11, enabling a detachable connection between the positioning alarm 20 and the lifebuoy body 10. The positioning alarm 20 and the mounting slot 11 are engaged via a snap-fit ​​assembly.

[0044] refer to Figure 5 and Figure 6 A convex-concave fitting component is provided between the bottom 112 of the mounting groove 11 and the bottom of the housing 21. The convex-concave fitting component includes a protrusion 12 protruding in the middle of the bottom 112 of the mounting groove 11 and a groove 23 recessed in the bottom of the housing 21. The protrusion 12 and the groove 23 are in convex-concave fit.

[0045] refer to Figure 2 , Figure 5 and Figure 6 The latching assembly includes one or more latching grooves 121 recessed on two opposite sides of the protrusion 12, and a latching protrusion 231 protruding from the corresponding position of the groove 23 and engaging with the latching groove.

(Reference) Figure 6 The bottom 112 of the mounting groove 11 is arranged along the axial direction of the life ring body 10, and the groove walls 111 of the two mounting grooves 11 are respectively arranged along the radial direction of the life ring body 10 (that is, the cross-sectional line of the groove wall 111 along the radial direction is a straight line parallel to the axis of the life ring body 10), which facilitates drainage after water enters between the mounting groove 11 and the shell 21.

[0049] The bottom 112 of the mounting groove 11 is an arc shape centered on the center of the lifebuoy body 10, with the bottom of the groove 11 being an arc. The distance between the two opposing groove walls 111 of the two mounting grooves 11 gradually increases outward from the center of the lifebuoy body 10. (Reference) Figure 2 The shell 21 is trapezoidal or wedge-shaped when viewed from the circumference of the life ring body 10, which makes it easy for the shell 21 to be inserted into the mounting groove 11 and fit into the mounting groove 11.

[0050] When the lifebuoy is not in use, the user can place the magnet 244 in the magnet receiving slot 243. The magnet 244 engages with the metal fixing part 242 and is positioned in the magnet receiving slot 243, at which point the electromagnetic switch 241 deactivates the positioning alarm module 22. When the lifebuoy is to be used, the operator simply removes the magnet 244 from the magnet receiving slot 243 to activate the positioning alarm module 22. The back of the magnet 244 has a rope connection part 2441 for mounting a rope 30. The rope 30 is fixed to the storage area of ​​the lifebuoy. When in use, simply removing the lifebuoy allows the rope 30 to pull on the magnet 244, causing the magnet 244 and the magnet receiving slot 243 to engage, thus activating the positioning alarm module 22.

[0051] Example 2: refer to Figure 7 Unlike Embodiment 1, in this embodiment, the housing 21 of the positioning alarm 20 is threadedly fixed to the mounting groove 11 of the lifebuoy body 10.

[0052] The intelligent lifebuoy also includes threaded fasteners (not shown in the figure). The bottom of the housing 21 has multiple threaded holes 203, and the lifebuoy body 10 has multiple through holes 13 that extend radially to the bottom of the groove 112 and correspond to the positions of the threaded holes 203. The threaded fasteners correspond one-to-one with the threaded holes 201, pass through the through holes 13, and are threadedly connected to the corresponding threaded holes 203 to thread-fix the housing 21 into the mounting groove 11. Example 3: refer to Figures 8 to 10 Unlike embodiments 1 and 2, in embodiment 3, the two opposite sides of the positioning alarm 20 are respectively connected with connecting straps 25. The ends of the two connecting straps 25 are provided with interlocking buckles. The two connecting straps 25 pass around the lifebuoy body 10 and are connected by the plug-in buckles, so that the positioning alarm 20 and the lifebuoy body 10 are tied together by the connecting straps.

[0053] In this embodiment, the alarm unit 223 includes a light alarm, and the housing 21 is provided with a light-transmitting window 204 for the light from the light alarm to pass through. The charging port is a wireless magnetic charging port.

[0054] Compared with existing technologies, this invention uses the magnetic attraction between a magnetic switch 241 and a magnetic trigger 242 to open / close the positioning alarm module 22. When the smart lifebuoy is idle or in its designated placement position, simply place the magnetic trigger 242 on the trigger slot 243. The magnetic trigger 242 will then engage with the metal part 242 and adhere to the housing 21. The magnetic switch 241 will then sense the magnetic trigger 242 and close the positioning alarm module 22. The magnetic trigger 242 is positioned by the attraction of the trigger slot 243, making it less prone to accidental triggering. When the smart lifebuoy is to be used, simply remove the magnetic trigger 242 from the trigger slot 243. The magnetic switch 241 will then no longer sense the magnetic trigger 242 and will open the positioning alarm module 22. This allows operators to quickly open the positioning alarm module 22 in emergencies. Furthermore, during use, the magnetic trigger 242 and the housing 21 containing the positioning alarm module are separated, preventing accidental closure of the positioning alarm module 22 during use, ensuring safe and reliable operation.

[0055] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the scope of the present utility model shall still fall within the scope of the present utility model.
