Description

Technical Field

[0001] This invention relates to the technical field of water rescue equipment, and in particular to an intelligent life jacket for cruise ships with automatic inflation and positioning functions. Background Technology

[0002] Life jackets are essential safety equipment in water activities, and their development has evolved from natural materials to synthetic materials, and from simple flotation devices to intelligent devices. Early life jackets used natural buoyancy materials such as cork and bamboo, which had limited buoyancy and were bulky to wear. With the development of synthetic materials technology, lightweight materials such as polyethylene foam and closed-cell sponge have been widely used, significantly improving buoyancy and durability. The advent of inflatable life jackets has made the equipment compact in its deflated state, making it easy to store and carry. In recent years, with the maturity of electronic communication technology, life jackets have gradually integrated positioning modules, automatic triggering devices, and optical signal indicators, enabling them to automatically send distress signals and indicate location after falling into the water, greatly improving search and rescue efficiency. Currently, life jackets are widely used in cruise ships, passenger ships, fishing operations, water sports, flood control and disaster relief, and low-altitude flights. Different scenarios have specific requirements for buoyancy levels, wearing methods, and triggering mechanisms, driving the continuous development of life jackets towards lighter weight, intelligence, and high reliability.

[0003] Traditional foam life jackets are bulky, inconvenient to store, and have a simple fixing structure. They are easily displaced or even detached from the body when impacted by water flow. Inflatable life jackets mostly use mechanical structures for triggering devices. They need to be actively pulled after falling into the water to inflate. Unconscious or injured people cannot operate them. Furthermore, they are prone to rust and leakage due to insufficient sealing during long-term storage. Summary of the Invention

[0029] Example 1

[0030] Reference Figures 1-3The first embodiment of the present invention provides a smart life jacket for cruise ships with automatic inflation and positioning functions. The device includes, specifically, an outer shell 101, a diode 102 adapted and installed on the side wall of the outer shell 101, a reflective strip 103 fixedly connected to the side wall of the outer shell 101, cuffs 104 opened on both sides of the outer shell 101, a fixing component 105 fixedly connected to the side wall of the outer shell 101, a positioning component 106 snapped onto the surface of the fixing component 105, a buoyancy component 107 disposed in the inner cavity of the outer shell 101, and an inflation component 108 communicating with the surface of the buoyancy component 107.

[0031] Furthermore, the fixing component 105 includes a fixing strap 105a fixedly connected to the side wall of the outer shell 101, and a magnetic buckle 105b fixedly connected to the end of the fixing strap 105a. The fixing component 105 also includes a hoop 105c sleeved on the side wall of the outer shell 101, and a limiting strap 105d fixedly connected to the surface of the outer shell 101. The fixing component 105 also includes a locking strap 105e movably connected to the inner wall of the limiting strap 105d, and buckles 105f fixedly connected to both ends of the locking strap 105e.

[0032] The hoop 105c is hollow, which makes it easy to fix the outer shell 101, thereby ensuring that the device can be fixed when flushed by water flow, thus improving the stability of the device. Several limiting bands 105d are provided to ensure the fixation of the locking band 105e and to ensure that the locking band 105e will not fall off.

[0033] Preferably, the positioning component 106 includes a mounting housing 106a that snaps onto the surface of the fixing strap 105a, a positioning button 106b disposed on the surface of the mounting housing 106a, a switch 106c disposed on the surface of the mounting housing 106a, and an insert block 106d fixedly connected to the side wall of the mounting housing 106a.

[0034] It should be noted that the locator fixedly installed inside the housing 106a is the Worldcom SJT-105 model. This locator features GPS + Beidou dual-mode positioning and supports LBS base station-assisted positioning, with a positioning accuracy of up to 2.5 meters. Its button layout is clear; in addition to the SOS emergency call button, it can also pre-store three frequently used numbers for one-click quick dialing, making it suitable for personal monitoring of the elderly and children, as well as for item tracking. In this device, the locator uses a detachable snap-fit ​​structure between the insert 106d and the fixing strap 105a, ensuring a stable connection during use and facilitating daily charging, maintenance, and replacement, thus improving the device's reusability and maintenance convenience.

[0035] In use, the user first puts the outer shell 101 on the torso, puts both arms through the cuffs 104, and adjusts the outer shell 101 to a close-fitting state. Then, the user pulls the locking strap 105e to slide it within the limiting strap 105d to a suitable tightness, and fixes the locking strap 105e with the buckle 105f. At the same time, the hoop 105c is put on the outside of the outer shell 101 and tightened to achieve double fastening of the device on the human body and prevent it from falling off due to water impact. After completing the wearing and fixing, the user inserts the positioning component 106 into the surface of the fixing strap 105a, so that the mounting shell 106a is engaged with the surface of the fixing strap 105a. At this time, the user presses the switch 106c to start the locator. The locator automatically acquires satellite signals to achieve real-time positioning and tracking of the person who has fallen into the water.

[0036] In summary, the locking strap 105e slides within the limiting strap 105d and is secured by the buckle 105f, allowing the outer shell 101 to be flexibly adjusted to fit the user's body shape, preventing it from coming loose after wearing. The hoop 105c is fitted onto the outside of the outer shell 101 and tightens it, making the outer shell 101 less prone to displacement under the impact of water flow. This eliminates the need for the user to frequently adjust the position of the life jacket after falling into the water, thus saving energy while waiting for rescue. The magnetic buckle 105b automatically engages at both ends of the fixing strap 105a, allowing the wearer to fasten the buckle without bending down. When the securing strap 105a is closed, the blind-operation feature of the magnetic buckle 105b reduces the difficulty of putting it on for users in a panicked state after falling into the water. Furthermore, the magnetic buckle 105b, once engaged, will not detach itself under sudden pulling force, preventing the securing strap 105a from accidentally coming loose. The mounting shell 106a engages with the slot on the surface of the securing strap 105a via the insert 106d, ensuring that the mounting shell 106a does not detach from the securing strap 105a during human movement or tumbling in the water, guaranteeing that the locator remains attached to the user. Meanwhile, the insert 106d... After the 06d is embedded in the slot, the mounting shell 106a does not slide along the surface of the fixing strap 105a. The positioning button 106b and the switch 106c are always in the same operating position, which the user can reach by touch in water where visibility is obstructed. The distress signal triggered by pressing and holding the positioning button 106b is sent out through the locator's built-in communication module, so that the rescuer can receive the alarm signal and obtain the location information in time, shortening the search time. The diode 102 lights up and emits a flashing light signal after falling into the water, providing a clear light for rescuers at night or in dense fog. The visual identifier, reflective strip 103, reflects the irradiated light into the surrounding environment, making the person who has fallen into the water visible from multiple directions and increasing the probability of being discovered. After unfastening the buckle 105f and loosening the hoop 105c, the outer shell 101 releases the restraint on the human body, making it easy for the user to quickly remove. After removing the mounting shell 106a, the positioning component 106 separates from the fixing strap 105a, and the locator can be taken out separately for charging and data reading. Pressing the switch 106c cuts off the power to the locator, preventing power consumption when not in use and extending standby time.

[0037] Example 2

[0038] Reference Figure 1 , Figure 4 as well as Figure 5 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the buoyancy component 107 further includes a foam 107a fixedly connected to the inner wall of the outer shell 101, and a filling sponge 107b fixedly connected to the surface of the foam 107a. The buoyancy component 107 also includes a flexible plastic 107c fixedly connected to the surface of the filling sponge 107b, and a cavity 107d disposed on the surface of the flexible plastic 107c.

[0039] Furthermore, the inflation assembly 108 includes a control valve 108a communicating with the inner wall of the cavity 107d, and a stop button 108b fixedly connected to the surface of the control valve 108a. The inflation assembly 108 also includes a probe 108c disposed on the surface of the control valve 108a, and an inflation head 108d communicating with the surface of the control valve 108a. The inflation assembly 108 also includes a baffle 108e threadedly connected to the surface of the inflation head 108d, and a gas cylinder 108f communicating with the surface of the control valve 108a.

[0040] In use, the gas cylinder 108f stores compressed gas and is connected to the surface of the control valve 108a. The control valve 108a is connected to the inner wall of the cavity 107d. The gas in the gas cylinder 108f enters the cavity 107d through the control valve 108a, causing the cavity 107d to expand and push the flexible plastic 107c outward. During the process of being pushed by the gas, the flexible plastic 107c compresses the filling sponge 107b. The filling sponge 107b deforms after being compressed by the flexible plastic 107c and fills the foam 107a. Within the surface gaps, foam 107a is fixedly connected to the inner wall of the outer shell 101, providing a supporting base for the filling sponge 107b and preventing it from detaching from the inner wall of the outer shell 101 after deformation. A baffle 108e is threadedly connected to the surface of the inflation head 108d, isolating it from the external environment when not in use and preventing foreign objects or moisture from entering the control valve 108a. A probe 108c is positioned on the surface of the control valve 108a, continuously monitoring the external water environment. When probe 108c contacts the water, it generates an electrical signal, which is transmitted to control valve 108a. Upon receiving the signal, control valve 108a automatically opens, allowing gas from cylinder 108f to flow along the pipeline to cavity 107d. Stop button 108b is fixedly connected to the surface of control valve 108a. After cavity 107d has expanded, the user presses stop button 108b, causing control valve 108a to close, blocking the gas passage between cylinder 108f and cavity 107d, and stopping further gas input into cavity 107d. When there is insufficient gas inside the cavity 107d, the user unscrews the cover 108e from the surface of the inflation head 108d to connect an external air source to the inflation head 108d. Gas is then supplied to the control valve 108a through the inflation head 108d, and the gas re-enters the cavity 107d through the control valve 108a. When it is necessary to vent the gas inside the cavity 107d, the user loosens the cover 108e to connect the inflation head 108d with the external environment, and the gas inside the cavity 107d is discharged outward from the inflation head 108d.

[0041] In summary, foam 107a is fixedly connected to the inner wall of the outer shell 101, providing a support surface for the filling sponge 107b. After deformation, the filling sponge 107b embeds itself into the gaps of foam 107a, increasing the contact area and friction, preventing the filling sponge 107b from falling off the inner wall of the outer shell 101. Flexible plastic 107c is fixedly connected to the surface of the filling sponge 107b. When the cavity 107d expands, it pushes the flexible plastic 107c to evenly transmit the expansion force to the surface of the filling sponge 107b, avoiding excessive local stress and indentation on the filling sponge 107b. Control valve 108a is connected to the inner wall of the cavity 107d, and gas cylinder 108f is connected to the surface of control valve 108a. Gas enters the cavity 107d directly through control valve 108a, reducing pressure loss during transmission. Probe 108c is set on the surface of control valve 108a, contacting... After the water body enters the system, the control valve 108a immediately receives the signal and opens the valve, reducing signal transmission delay. The stop button 108b is fixedly connected to the surface of the control valve 108a. When pressed, the control valve 108a directly closes the valve, providing immediate operation feedback. The baffle 108e is threadedly connected to the surface of the inflation head 108d. When tightened, it forms a sealed layer, preventing seawater and particulate matter from entering the interior of the control valve 108a. The inflation head 108d can be connected to the external air source by hand. The inflation head 108d is connected to the surface of the control valve 108a. External gas enters the cavity 107d through the control valve 108a. The supplementary gas and the initial inflation share the same channel. Loosening the baffle 108e allows the inflation head 108d to connect with the external environment. The gas inside the cavity 107d is discharged outward along the inflation head 108d under the action of pressure difference, without the need for suction equipment.
