Description

An underwater life jacket with a luminous device

technical field

The invention relates to a luminous lifejacket, in particular to a wireless charging, waterproof, light, bendable underwater lifejacket with a luminous device.

Background technique

Life jackets are personal protective equipment, also known as water protective clothing, widely used in aircraft, passenger ships, commercial fishing boats, warships, yachts, offshore drilling platforms and other water operations. The lifejackets currently used are simple in structure and lack of function. Especially in some accidents on the sea and other water, although the drowning person has a lifejacket floating on the water surface, the search and rescue personnel are difficult to find the target at night and cannot rescue the person who fell into the water.

Existing lifejackets only have a small part equipped with reflective film or lifejacket lights, and the lifejackets with reflective film are difficult to be found at night. Existing lifejacket lamps include batteries, lamp clips, lamp holders, bulbs and lampshades. The lamp clips and lamp holders are embedded with electric bulbs to emit light. The light bulbs have poor luminous efficiency, high power consumption, short working time, large volume, and are not easy to carry. . When the power of the battery is exhausted, the lifejacket light cannot work. The battery is usually charged in a wired manner. It needs to be charged through an interface and a wire. It is necessary to install the interface and wires on the lifejacket light, resulting in the overall waterproof of the lifejacket light and low performance. Unreliable for long-term use, installation, and storage in harsh environments such as water or continuously wet environments.

Contents of the invention

The object of the present invention is to solve the above problems, to provide a lifejacket in water with a light-emitting device, which adopts wireless charging, is convenient to charge, is waterproof, light, and can be bent into different shapes. Luminous life jackets are used in airplanes, passenger ships, commercial fishing boats, warships, yachts, offshore drilling platforms and other water operations.

The underwater lifejacket with light-emitting device according to the present invention is composed of an internal wireless charging receiving module, a light-emitting diode, a wireless rechargeable battery, a resistor, a light-emitting diode drive circuit, a system control circuit, a flexible circuit board, an outer packaging transparent rubber cover humidity sensor and It consists of a light touch switch and an external wireless power supply module separated from the lifejacket.

The wireless charging module includes an external wireless power supply module emitting electromagnetic waves and an internal wireless charging receiving module receiving the electromagnetic waves and converting them into alternating currents, which are then rectified and filtered into direct currents to charge the battery. An external wireless power supply module can charge multiple internal wireless charging receiving modules by emitting electromagnetic waves, and the rechargeable battery uses a lithium battery.

The light-emitting diodes are color light-emitting diodes, including ordinary color light-emitting diodes and high-brightness color light-emitting diodes. A color light-emitting diode and a resistor are connected in series to form a basic unit, and several basic units can be connected in series, parallel, or mixed; multiple color light-emitting diodes are installed on a plane in the form of an array to form a color light emitting diode. Diode matrix screen, dot matrix screen has various colors, divided into single color, double color, three colors. The color light-emitting diodes are evenly distributed on the flexible circuit board in a matrix shape, and can be arranged and combined to form an indicator or warning icon light-emitting display.

The light-emitting diode driving circuit can adopt a discrete element driving circuit or an integrated driving circuit.

The system control circuit can adopt: a micro button switch control circuit; a microprocessor control circuit to control the humidity sensor and trigger. The touch controller and tact switch are controlled manually.

The flexible circuit adopts a flexible circuit board with excellent performance, so the life jacket can be bent, and the protective layer and the circuit are not easy to fall off.

The outer packaging transparent rubber sleeve is used to protect the entire life jacket light-emitting bagging circuit and control the charging internal system, and the entire life jacket light-emitting block is firmly enclosed in the outer packaging transparent rubber sleeve. Therefore, the life jacket light-emitting device has a highly reliable waterproof performance, and The appearance is flat and smooth.

The light-emitting life jacket can be made into different shapes such as rods, blocks, and rings according to user needs, and fixed on the life jacket for single-sided, double-sided, and multi-sided luminous display.

Lifejackets are generally placed in fixed positions in batches, and mobile or fixed wireless chargers can be used to charge multiple lifejacket light emitting devices at regular intervals. The internal communication function can be added to the wireless charging system of the lifejacket light emitting device, and when the charging power of a single lifejacket light emitting device is insufficient, the wireless charging system can charge a single lifejacket.

The working voltage of the underwater lifejacket with a luminous device is 3-6v direct current.

The beneficial effect of adopting this technical solution is: it has highly reliable waterproof performance, and the appearance is flat and smooth, and can be bent into various shapes; the logo is bright in color, sharp in contrast, eye-catching and dazzling, and has good indication and warning effects; wireless charging is convenient for charging , The light-emitting diode consumes less power, and the life jacket works for a long time.
