SUMMERY OF THE UTILITY MODEL

To the problem that mentions in the background art, the utility model aims at providing an intelligent safety helmet can accurately judge whether be in the state of wearing, and then is convenient for carry out safe warning.

The above technical purpose of the present invention can be achieved by the following technical solutions: an intelligent safety helmet comprises a lining, wherein a flexible pressure sensor module is arranged on the inner surface of the lining; the flexible pressure sensor module is attached to the inner wall of the lining and comprises a flexible pressure sensor and a thin film layer, the thin film layer is located on the front side and the back side of the flexible pressure sensor, and the flexible pressure sensor module is located at the forehead position of the lining.

Preferably, the width of the flexible pressure sensor module is not more than 15 mm, wherein the width of the flexible pressure sensor module is not more than 10 mm, and each film layer is not more than 2.5 mm.

Preferably, the contact pitch of the flexible pressure sensor module is 7.62 mm.

Preferably, the contact 1 of the flexible pressure sensor is grounded, the contact 2 of the flexible pressure sensor is connected with external voltage through a resistor R1, and the contact 2 is also connected with an external output signal circuit through an operational amplifier.

To sum up, the utility model discloses mainly have following beneficial effect: the utility model discloses an intelligent safety helmet, through design on the inside lining have flexible pressure sensor, combine the human body to the design at the position of wearing of safety helmet, thereby realize whether wearing the safety helmet and accurately judge, and make laminating between the forehead position that can be stable and people and the inside lining through size design, do not influence the normal wearing of safety helmet, can also realize reequiping the upgrading to current safety helmet structure, can network with the thing networking management system of present job site simultaneously, carry out safe warning and personnel's record to the constructor who does not wear the safety helmet, the phenomenon of misjudgement because of the mistake is touched in the position of design is difficult to appear, and then whether the safety helmet is in the recognition accuracy of wearing; and meanwhile, the design of the flexible pressure sensor matched with the film layer can effectively prevent the secondary damage of devices such as the sensor to the head when the safety helmet is impacted.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.

The intelligent safety helmet comprises a lining 1, wherein the lining 1 can be made of reinforced plastics, and a flexible pressure sensor module 3 is pasted on the inner surface of the lining 1; the flexible pressure sensor module 3 comprises a flexible pressure sensor 31 and film layers 32, the film layers 32 are positioned on the front and back sides of the flexible pressure sensor 31, and the flexible pressure sensor module 3 is positioned on the forehead part of the lining 1; when wearing the safety helmet, people's forehead position can be because of the extrusion to flexible pressure sensor module 3, and makes flexible pressure sensor module output sensing signal, and then makes accurate judgement site operation personnel whether wear the safety helmet, and operations such as simple handheld safety helmet are to flexible pressure sensor 31's extrusion mode, and on the one hand to the handheld comparison difficulty of forehead position, moreover also more difficult to trigger flexible pressure sensor 31's sensing signal.
