Description
Technical Field
The utility model belongs to the technical field of wearing detection of safety helmets, and particularly relates to a safety helmet lining capable of monitoring the wearing state.
Background
The helmet liner is an important component of the helmet. The helmet is composed of an upper top belt, a chin belt, a helmet hoop, a tightening mechanism and the like, and has an important protection function on the head safety of operators in the production operation process, so that whether the operators wear the helmet or not and whether the wearing of the helmet is normal or not are always the important concerns of people.
The current method for detecting whether the worker wears the safety helmet mainly comprises the following steps:
(1) Electronic elements are arranged in the male buckle and the female buckle of the chin strap, and when the male buckle and the female buckle are buckled, electronic signals trigger, so that the safety helmet is judged to be worn. This approach has a significant localization. Since the chin strap is generally of a margin length, the method cannot judge whether an operator wears correctly or not, and the possibility of false exists.
(2) In order to prevent the worker from wearing the helmet to make a false, a scheme for detecting the wearing condition of the helmet by using an image is proposed, but obviously, the scheme can only be detected at a place with a camera and has a great limitation.
(3) In order to solve the above problems, people find that when the safety helmet is worn normally, a tightening action exists, so that the lining and the lacing can generate certain pressure on the skin of the head, and then people put forward to add a pressure sensor in the chin guard of the chin strap, and when the safety helmet is tightened, whether the safety helmet is worn normally is judged by detecting the parameters of the pressure sensor. As the chin is one of the most frequent parts of human body movement, the problems of high system misjudgment rate, abrasion of devices and the like are brought. To solve this problem, some people place the pressure sensor between the top of the head and the inner liner, but since the hair acts as a buffer, there is a great influence on the sensitivity of the pressure sensor, and some people with thicker hair may not be able to detect. For this reason, it is desired to solve this problem by increasing the number of pressure sensors, for example, by increasing the number of pressure sensors between the belt and cheek, between the temple and the inner liner, etc., so that the pressure sensors accurately sense the pressure applied to the head, but these increased sensors cause not only discomfort to the user but also a great increase in cost.
The utility model provides a detect the defect that detection scheme was worn to current safety helmet, provides a detect the position few, strong adaptability to wearing the position, and sensitivity is high, receives the external disturbance few can wear the safety helmet inside lining of state monitoring.

Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
First embodiment:
referring to fig. 1-3, the utility model is a safety helmet liner capable of monitoring wearing state, comprising an upper top belt 1, a chin belt 2 and a helmet hoop 9; four end parts of the two upper top belts 1 after cross interlacing are fixed on the cap hoop 9, and sponge gaskets are arranged at the cross interlacing parts in a penetrating way; the two ends of the chin strap 2 are respectively connected with the hat hoop 9, and also comprise a control box 4, a wire harness 5, a first lacing fixing clamp 6, a tension sensor 7 and a second lacing fixing clamp 8; the first lacing fixture 6 is fixed at one point of the upper top strap 1/the chin strap 2; the second lacing fixing clip 8 is fixed at the other point of the upper top strap 1/the chin strap 2; the tension sensor 7 includes a sensing block 71 and a strain gauge 72 provided on the sensing block 71; the two ends of the sensing block 71 are respectively provided with a first stress endpoint 73 and a second stress endpoint 74; the sensing block 71 is bridged between a first stress end point 73 and a second stress end point 74; the first stress end point 73 is fixed on the first lacing fixture 6; the second force receiving end 74 is secured to the second lace retaining clip 8; the tension sensor 7 is connected with the control box 4 along the upper top belt 1/the chin belt 2 and the cap hoop 9 through the wire harness 5; the control box 4 is mounted on a cap hoop 9.
Wherein, a key 401, a control board 402, a cap hoop tightening mechanism 403, an audio input/output unit 404, a battery 405, a vibration sensor 406 and an LED lamp 407 are arranged in the control box 4; the battery 405 is used to power the tension sensor 7, the control board 402, the vibration sensor 406, and the LED lamp 407; the control board 402 processes and transmits signal data of the tension sensor 7; the cap band tightening mechanism 403 is used for tightening the cap band 9; the key 401, the LED lamp 407 and the audio input/output unit 404 are used for user interaction, when the safety helmet is abnormally worn, the user or other people can be prompted by making a sound through the audio input/output unit 404 or flashing light of the LED lamp 407, and the prompts can be temporarily closed through the key 401 according to actual conditions; vibration sensor 406 feeds back the tightening action and control board 402 can perform energy-saving control of the system through detection of the tightening action. The cap strap tightening mechanism 403 is a knob-type fastener or a button-type fastener.
The application regards the mechanical system of the safety helmet worn qualified as a fixed pulley system. Because the tension is approximately equal in the fixed pulley system on the upper top belt 1 or the chin belt 2, the wearing state of the helmet can be known only by detecting the tension at one point. The tension sensor 7 can be arranged on the upper top belt 1 or the chin belt 2, but the detection effect of the tension sensor and the chin belt is slightly different.
When the tension sensor 7 is installed on the upper top belt 1, the tension T1 is applied to the upper top belt 1 under the action of the tightening tension force after a user tightens the upper top belt 1 before the safety helmet is not tightened, and the threshold values T1 and T2 of T1 and T2 and the suspended state threshold value T0 are respectively set. The current wearing state of the safety helmet can be judged according to the current data t of the tension sensor:
(1) When T is less than T0, the helmet is not worn;
(2) T1> T > T0, the helmet is worn without tightening;
(3) When T2 is less than T, the safety helmet is worn and is in a tightened state;
when the tension sensor 7 is mounted on the chin strap 2, it is not possible to sense the weight of the helmet itself, and therefore, it is only possible to determine whether the helmet is in a worn and tightened state.
Both of the above-described mounting methods are possible if only the state in which the helmet is worn and tightened is detected.
From this, the inventive design has two advantages: 1. the tension of the upper top belt 1 or the chin belt 2 can be tested without designating a specific test point, and in the whole stress test, only one point is needed to be tested, so that the multipoint test is not needed, and even if the position deviation occurs in use, the detection data is not influenced; 2. the tension sensor 7 does not need to be in contact with the skin, regardless of the relative position of the head, and is not affected by hair, head movements and the position of the head within the cap. The use requirement on a wearer is greatly reduced, the complexity of the system is reduced, the possibility of misjudgment is reduced, and the reliability of the system is improved.
