Description

Vehicle-mounted infant intelligent safety seat with safety alarm device

Technical Field

The utility model relates to a vehicle-mounted safety seat technical field particularly, relates to a vehicle-mounted infant intelligent safety seat with safety alarm device.

Background

As the automobile as a daily vehicle enters a common family, the occurrence of vicious events such as injury, disability and even death of children staying in the automobile caused by high temperature or harmful gas injury is increasing. In China, in reported cases of high-temperature death of infants, whether the first-line large city of wide and deep north or the second-line city such as Hangzhou and Nanjing, such tragedies occur every year, and cause a lot of family and social tragedies. In addition, according to the incomplete statistics of the road traffic safety bureau in the united states, the death of infants and young children caused by careless carelessness of parents or school bus drivers in the united states is over 800 years in recent 20 years, especially in recent years. The number of infant disability, paralysis and carcinogenesis caused by high temperature, oxygen deficiency in the automobile, excessive formaldehyde, benzene, toluene and the like is not calculated.

At present, domestic research and production enterprises of child safety seats pay enough attention to safety indexes forcibly required by the state, and design and exploration carried out on the seat attractiveness and comfortableness, such as styles, cushion heat dissipation and materials, are common based on marketing needs, but few reports are given to thinking about safety of the safety seats and the whole vehicle, facility safety, and particularly functional protection measures aiming at accidents caused by the loss of parent experience, common knowledge or negligence.

The existing in-vehicle safety alarm system usually judges whether a vehicle stops or not by detecting whether an automobile key is in a key hole or not, if the in-vehicle safety alarm system is in a flameout state, a camera or an infrared sensor is started to judge whether vital signs exist in the vehicle or not, if the in-vehicle safety alarm system is in the flameout state, a carbon dioxide sensor is started to monitor carbon dioxide in the vehicle, and when the numerical value of the carbon dioxide meets an alarm condition, an alarm is given out. Some systems still set up temperature sensor simultaneously, when the numerical value of carbon dioxide satisfied the alarm condition, start temperature sensor simultaneously, detect the interior temperature of car, if the temperature is too high, still can send the suggestion of stifling simultaneously and report to the police.

However, the above system may have a safety problem in that the infant may be left on the vehicle by accident, but in reality, the situation is relatively rare, and in most cases, the adult may leave the vehicle for a while to leave the infant on the vehicle, and at this time, the air conditioner may be turned on instead of turning off the fire in order to keep the air in the vehicle good. At this time, the in-vehicle alarm system cannot be triggered to start at all, so that the in-vehicle safety condition cannot be monitored, and no matter what the in-vehicle alarm system alarms in time. However, according to data, direct solar radiation in summer causes the temperature in a closed space in a car to suddenly rise, if the temperature is over 34 ℃ outdoors, the temperature in the car can reach 65 ℃ within 15 minutes (the data show that water at about 60 ℃ can cause second-degree scald of infants), the internal organ damage and brain damage of liver and kidney can be caused by the environmental temperature, and the occurrence of heat radiation disease is also the main reason for death of the events.

According to research of Shenyang university 'design and manufacture of anti-asphyxia device in vehicle': the interior of the vehicle has strong sealing performance. This is because the air pressure does not change due to the breathing of a person, unlike the situation where the air flow around the vehicle is accelerated to form a negative pressure when the vehicle is stationary and stopped. So to speak, when the vehicle is not in motion, the air in the vehicle has no power at all to exchange. The data show that the resting metabolic rate of adults is about 200ML of oxygen per minute. At high temperature, the oxygen demand is increased by doubling, if the child cries, the oxygen demand is larger, at the moment, the oxygen demand in the vehicle is reduced, and the carbon dioxide concentration is increased. According to the examination of the fatality rate, the carbon dioxide concentration has great harm to human life. The concentration of carbon dioxide in the air is only 0.03%, and when the content of carbon dioxide exceeds 1%, a person has slight dizziness reaction; when it exceeds 3%, dyspnea begins to occur; if the concentration exceeds 6%, the patient can be severely anoxic and suffocated and even die.

The air conditioner is opened for a long time to wait under the condition of idling of the automobile, so that automobile tail gas and carbon monoxide can be circulated into the automobile, and people in the automobile are poisoned. In addition, reports show that the interior of a new car contains a plurality of toxic substances seriously harmful to the health of human bodies, and benzene, toluene, ethylbenzene, xylene and styrene have carcinogenicity and teratogenicity; formaldehyde, acetaldehyde and acrolein have carcinogenic effects, and stay in the environment polluted by harmful gases for a long time, cause dizziness, nausea, allergy, asthma and the like, and cause immune disorder of the organism, influence the functions of the central nervous system and the digestive system, damage the liver and the hematopoietic system, and cause leukemia, cancer and the like.

Therefore, there is a need to provide an improved safety alarm system, which can effectively monitor the safety of the infant in the vehicle without flameout and give an alarm in time.
