The utility model provides a pair of helmet alarm device, as shown in fig. 1 and fig. 2, including casing 1 and circuit assembly (not marked), circuit assembly includes circuit board 20 to and set up warning control circuit 21 and light source subassembly 22 on circuit board 20, warning control circuit 21 is used for responding to outside warning signal and drives light source subassembly 22 shows the light and reports an emergency and asks for help or increased vigilance.

The housing 1 includes a cover 10, a cover plate 11 and a waterproof rubber cover 12.

The cover 10 is provided with a receiving groove 101 (the mark refers to fig. 6) for receiving the circuit assembly 2, and a surface of one end of the cover opening of the cover 10 is shaped into an arc with a concave middle and two high sides.

Referring to fig. 3, the cover plate 11 includes a base plate 110 and a boss 111 disposed on the base plate 110, and an arc surface 1100 with a concave middle and two high sides is formed on the outer side of the base plate 110 and is fittingly mounted with the arc of the cover opening of the cover body 10. The arcuate surface 1100 is shaped to conform to the profile of a helmet. The boss 111 is disposed on the arcuate surface 1100. The length and width of the boss 111 are smaller than those of the substrate 110, that is, a brim portion 1101 is outwardly opened relative to the boss 111 outside the substrate 110.

The cover plate 11 is of an integrally formed structure.

Referring to fig. 4, 5 and 6, the structure of the waterproof rubber sleeve 12 is fitted to the shape of the cover plate 11, so that the waterproof rubber sleeve 12 sleeves the cover plate 11. Specifically, the waterproof rubber cover 12 includes a protrusion 121, a skirt 122 flaring outward relative to the protrusion 121, and an arc-shaped opening 125 surrounded by the skirt 122. When the waterproof rubber cover 12 sleeves the cover plate 11, the skirt portion 122 is opened outwards relative to the base plate 110 of the cover plate 11, and the base plate 110 is located at the arc-shaped opening 125 of the waterproof rubber cover 12; the shape and size of the brim part 1101 are matched with the inner surface of the step part 123 at the joint of the protrusion 121 and the skirt part 122, the shape and size of the boss 111 of the cover plate 11 are matched with the shape and size of the protrusion 121 of the waterproof rubber sleeve 12, when the cover plate 11 is sleeved on the waterproof rubber sleeve 12, the groove structure in the protrusion 121 accommodates the cover plate 11, and the brim part 1101 is arranged on the inner surface of the step part 123. The skirt 122 is arc-shaped, and because it is a flexible material, it has a certain flexibility, and it flares outwards relative to the protrusions 121, so that it can adapt to helmets of different arcs when in use.

The waterproof rubber sleeve 12 is of an integrally formed structure.

When the cover 10, the cover plate 11 and the waterproof rubber cover 12 of the housing 1 are installed in a sleeved manner, referring to fig. 6 and 7, the cover plate 11 is sleeved by the waterproof rubber cover 12, the waterproof rubber cover 12 is sleeved by the cover 10, and the boss 111 of the cover plate 11 is inserted into the accommodating groove 101 of the cover 10, so that the accommodating groove 101 is covered by the substrate 110. When the cover 10 is covered with the waterproof rubber cover 12, the outer surface of the step portion 123 of the waterproof rubber cover 12 is tightly attached to the groove edge 102 of the accommodating groove 101, and the step portion 123 of the flexible material and the groove edge 102 of the cover of the rigid material form a first waterproof structure a. Because the first waterproof structure A is formed by laminating a flexible material and a hard material, the contact of the flexible material and the hard material is better than the contact of the flexible material and the hard material, and the laminating tightness is better, so the waterproof performance is also better. In addition, when the cover plate 11 is sleeved with the waterproof rubber sleeve 12, the brim portion 1101 of the cover plate 11 is tightly bonded to the inner surface of the terrace portion 123, and the bonding at this position is similarly made of a flexible material and is bonded to a rigid material, so that the waterproof performance is good.

The helmet alarm device provided by the utility model prevents water vapor from entering the containing groove 101 of the cover body 10 by arranging the multiple waterproof structures, so that the waterproof performance of the device is ensured, and the service life of the device is prolonged.

Referring to fig. 4, 6 and 8, the side of the protrusion 121 of the waterproof rubber cover 12 is formed with at least one convex ring-shaped member 124, such as two ring-shaped members 124 in the present embodiment. When the cover plate 11 and the cover body 10 are covered, the annular member 124 and the inner sidewall 102 of the cover body 10 form a second waterproof structure B in an interference fit manner. The two annular members 124 of the second waterproof structure B are in interference fit with the inner side wall 105 of the cover 10, respectively, and perform a double-blocking function on part of the water vapor entering the gap between the side surface of the protruding portion 121 of the waterproof rubber sleeve 12 and the inner side wall 105 of the cover 10, so as to prevent the part of the water vapor from entering the accommodating groove 101.

The bottom of the cover 10 is provided with a plurality of studs 103, and the studs 103 at least partially contact the bosses 111. Referring to fig. 6 and 9, the stud 103 abuts against the detent 1111 of the boss 111 to define the position of the stud 103 for easy installation. The top of the protrusion 121 of the waterproof rubber sleeve 12 is provided with a locking portion 126, and when the cover 10, the cover plate 11 and the waterproof rubber sleeve 12 of the housing 1 are mounted in a sleeved manner, the locking portion 126 is located between the top of the boss 111 and the stud 103. The screw 13 passes through the boss 111 and the locking part 126 of the waterproof rubber sleeve 12, and is screwed with the stud 103 to form a third waterproof structure C. In other embodiments, the stud 103 may also directly abut against the top of the boss 111, and the screw 13 directly passes through the boss 111 to be screwed with the stud 103. Because the locking portion 126 sandwiched between the top of the boss 111 and the stud 103 is made of a flexible material, when the screw 13 is used to screw-lock the cover 10, the cover plate 11 and the waterproof rubber sleeve 12 of the housing 1, the contact portions of the cover 10, the cover plate 11 and the waterproof rubber sleeve 12 are made to be closer, so that the water vapor coming from the second waterproof structure B can be prevented from further entering the accommodating groove 101 for accommodating the circuit assembly 2, and the circuit assembly 2 is protected. The cover 10 is an integrally formed structure.
