Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1 and 3, a voice prompt safety helmet mainly comprises a helmet shell body 1, a helmet liner 4, a mandible belt 3 and a rear neck hoop 5, wherein the helmet shell body 1 is wholly hemispherical and made of elastic high-strength materials, and when the safety helmet is impacted, the kinetic energy of the helmet shell body 1 during impact is mainly borne. The cap liner 4 is arranged at the concave part of the cap shell body 1, a certain gap is reserved between the cap liner 4 and the cap shell body 1, and the cap liner 4 is used for buffering and dispersing kinetic energy so as to reduce direct damage to the head when the safety helmet is impacted.

Referring to fig. 2, the helmet shell body 1 is symmetrically provided with a pair of movably connected mandibular bands 3 at the bottoms of both sides centering on the visor, the mandibular bands 3 being adjustable in size according to the actual needs of the worker, and the mandibular bands 3 are connected by means of eye-splices (not shown in the figure).

Referring to fig. 2 and 4, a back neck hoop 5 whose size can be adjusted according to the head circumference of the wearer is extended and fixed backwards on both sides of the cap liner 4, the back neck hoop 5 is at the back of the cap shell body 1 and is in a semicircular shape, the back neck hoop 5 is mainly made of plastic material, and a cylindrical knob 6 for adjusting the size of the back neck hoop 5 is fixed on the outer side of the back neck hoop 5 at the vertex of the semicircular shape.

Referring to fig. 5 and 6, a rectangular mounting plate 7 is fixed on one side of the back neck strap 5 away from the knob 6, and second mounting holes 17 are formed at four corners of the mounting plate 7. The first pressure sensor 8 is glued on the mounting plate 7, two edges on the side surface of the first pressure sensor 8 are arc-shaped, when a worker wears the mounting cap, the first pressure sensor 8 is in contact with the head of the worker, and the arc-shaped edges can increase the comfort level when the worker wears the safety cap. The mounting cover 11 is arranged above the mounting plate 7, the mounting cover is cuboid, the bottom of the mounting cover extends towards the periphery to form an extension part 19, and first mounting holes 16 are formed in four corners of the extension part 19. The bolt 18 passes through the first mounting hole 16 and the second mounting hole 17 to fix the mounting cover 11, the central portion of the mounting cover 11 is separately provided with a sensing port 12 with the same size as the first pressure sensor 8, and one end of the first pressure sensor 8 far away from the mounting plate 7 passes through the sensing port 12.

Referring to fig. 4, a lining cloth 13 for increasing the wearing comfort of a worker wearing the mounting cap is attached to one side of the back neck hoop 5 away from the knob 6, one end of the lining cloth 13 is integrally connected to the back neck hoop 5, a hasp 14 with a U-shaped side surface is fixed to the other end of the lining cloth 13, and a loop 15 matched with the hasp 14 is fixed to the back neck hoop 5. The size of one U-shaped section of the hasp 14 inserted into the hasp ring 15 is longer than that of the other U-shaped section of the hasp 14 connected with the lining cloth 13, and the hasp 14 can increase the firmness of the hasp 14 inserted into the hasp ring 15 through the arrangement when the hasp 14 is inserted into the hasp ring 15.
