Description

Technical Field

[0001] The invention relates to the technical field of waterproof indicator lights, in particular to a small water surface towable waterproof indicator light with a built-in battery. Background Art

[0002] A small surface towed indicator light is a portable lighting and warning device designed specifically for the water surface. It generally emits bright light through an LED lamp to warn, making it easier for operators to observe the water surface and the operating equipment, so as to understand the dynamic situation on the water surface and underwater and respond accordingly.

[0003] Similar devices currently require replacement of dry batteries each time they are used, increasing battery costs. Furthermore, some products cannot switch colors, and when used alternately during the day and at night, they are generally replaced with new products, which is time-consuming and labor-intensive. Furthermore, most products are manually assembled, and the sealing effect is greatly affected by repeated disassembly and assembly operations, as well as when they are impacted or dropped, thereby increasing the risk of water ingress and decommissioning. Summary of the Invention

[0004] (1) Technical problems solved In view of the shortcomings of the existing technology, the present invention provides a small water surface towable built-in battery waterproof indicator light, which solves the problems of increased battery costs, frequent replacement of new products, and sealing being affected by water ingress and becoming scrapped.

[0005] (2) Technical solution To achieve the above objectives, the present invention is implemented through the following technical solutions: a small water surface towable built-in battery waterproof indicator light, comprising a lower cover, a translucent upper cover is provided on one side of the lower cover, the contact points of the translucent upper cover and the lower cover close to the center and away from the center are respectively welded with through holes, a PCBA main control circuit board is fixedly installed on the inner side of the translucent upper cover, a surface of the PCBA main control circuit board close to the translucent upper cover is fixedly installed with a plurality of LED lights, a charging probe is fixedly installed on the inner side of the lower cover, one end of the charging probe passes through the lower cover and extends to the outer The end of the charging probe near the translucent upper cover contacts the main control circuit board of the PCBA. The PCBA and the charging probe are electrically connected. A lithium battery is fixedly mounted in the inner cavity of the lower cover, which is electrically connected to the main control circuit board of the PCBA. A contact switch is fixedly mounted on one side of the lower cover at the connection point. A spring is connected to the inner side of the contact switch, which is electrically connected to the main control circuit board of the PCBA. The contact switch can be turned on or off by touching the switch position three times in a row, and the lighting mode can be switched by touching the contact switch twice in a row. Through-hole welding is performed at the contact points near and far from the center of the circle between the translucent upper and lower covers, effectively controlling glue overflow at the melting point and providing a double-layer waterproofing effect. This significantly improves the protection effect compared to conventional single-layer welding and increases the strength of the connection between the two structural components. By arranging the lithium battery and the charging probe to cooperate with each other, the lithium battery can be charged through the charging probe, thereby completing multiple uses. By cooperating with the main control circuit board of the PCBA, the user can adjust the color of the LED light on the main control circuit board of the PCBA through the contact switch.

[0006] Preferably, a charger housing is provided on one side of the lower cover, and a charger lower housing is fixedly mounted to the side of the charger housing away from the lower cover via bolts.

By providing an electrical connection between the charging PCBA and the USB plug, charging can be performed through the charging PCBA.

[0007] Preferably, an anti-skid pad is fixedly connected to the inner side of the lower shell of the charger away from the lower cover, and the anti-skid pad is made of rubber. By setting the anti-skid pad to be made of rubber, the friction is increased, making the lower shell of the charger more stable when placed.

[0008] Preferably, a second ceramic ring and a first ceramic ring are fixedly connected to the inner center of the ends of the lower cover and the translucent upper cover that are separated from each other. The second ceramic ring and the first ceramic ring have the same caliber, and the inner surfaces of the second ceramic ring 9 and the first ceramic ring 6 are configured to be smooth. The smooth surface of the second ceramic ring and the first ceramic ring reduces friction. The use of ceramic material and the high heat dissipation effect of ceramic allow the wire to effectively dissipate heat during high-speed friction, reducing fatigue caused by heat during high-speed friction and increasing the service life of the wire.

[0009] Preferably, an eccentric counterweight is fixedly sleeved on the inner side of the lower cover away from the center, and the center of the eccentric counterweight corresponds to the center of the lower cover. The eccentric counterweight is provided to make the product more stable in water.

[0010] Preferably, a groove is provided on the outer side of the lower cover, and the end of the charging probe away from the translucent upper cover is located inside the groove. By providing the groove, the charging probe can be limited by the groove during charging, making the charging probe more stable during charging.

[0011] Preferably, the side of the charger housing away from the charger lower housing mates with the outer surface of the lower cover, and the contact surface between the charger lower housing and the lower cover is configured to be smooth. By configuring the charger housing to mate with the outer surfaces of the lower cover, the charger housing restrains the lower cover, making the lower cover more stable during charging.

[0012] (3) Beneficial effects The present invention provides a small water-surface towable waterproof indicator light with a built-in battery. It has the following beneficial effects: By performing through-hole welding at the contact points of the translucent upper cover and lower cover close to and away from the center of the circle, the overflow of glue at the melting position can be effectively controlled, while playing the role of double-layer waterproofing. The protective effect is significantly improved compared to conventional one-layer welding, and the strength of the connection between the two structural parts is increased.

[0013] By arranging the mutual cooperation between the lithium battery and the charging probe, the lithium battery can be charged through the charging probe, thereby completing multiple uses.

[0014] By cooperating with the contact switch and the PCBA main control circuit board, the user can adjust the color of the LED light on the PCBA main control circuit board through the contact switch.

[0015] The method of turning on / off / switching the light mode is realized by multiple touches, which effectively prevents the touch switch from accidentally touching the conductor and solves the problem of abnormal lighting of the device in water. BRIEF DESCRIPTION OF THE DRAWINGS
