Description

Automobile cushion capable of quickly eliminating body fatigue and automatically ventilating and perspiring

Technical Field

The utility model relates to a car cushion field specifically is a car cushion that can eliminate body fatigue fast and automatic ventilative perspire.

Background

The automobile seat cushion products on the current market are various in types, but the automobile seat cushion products cannot really achieve the functions of synchronously and quickly eliminating driving fatigue in the driving process and automatically ventilating and perspiring. As shown in fig. 1, most of the existing car seats lack strong support for the body in the caudal vertebra, lumbar vertebra and cervical vertebra, and directly generate serious lever effect of the human body, and the weight pressure of the upper body of the human body is transmitted to the caudal vertebra part along the vertebral column, so that the lever effect of the caudal vertebra part is very serious. Injury of the coccyx causes premature senility and fatigue of coccyx. The lever effect of the caudal vertebra part can extend upwards along the vertebral column, thus aggravating the lever effect of the lumbar vertebra part, inducing the instinct release of the human body balance danger, promoting the muscle groups of the waist, the back and the hip to be in a tense state for a long time, maintaining the balance of the body, consuming a large amount of energy, causing the body fatigue, and aggravating the driving fatigue and the waist soreness and backache. The long-term fatigue of the body can cause permanent damage and cause pathological changes after long-term fatigue.

Meanwhile, a large amount of sponge is filled in the automobile seat and the automobile cushion, and the sponge is soft, comfortable and low in cost. General sponge, latex sponge, memory cotton, rubber sponge etc. no matter which kind of sponge, all are loose poroid structural material, and the sponge compressive support intensity is very poor in the vertical direction, only 3 ~ 15 kilograms, is far below the health weight, and the atress can be flattened easily, can not stably support the weight. As shown in fig. 2, the hole-shaped structure can be deformed from different angles, so that the sponge product is difficult to stabilize in shape, and when the sponge product is stressed, most of the area is easy to displace and shake, so that new human body leverage is continuously generated, and related muscle groups of the back, the waist and the hip are always in a tense state, so that the body is tired, soreness and backache. As shown in figure 3, the porous structure is easy to break, damage and collapse during use, permanent deformation cannot be made up, compression resilience is poor, pressure transmission is unbalanced, the buffering and vibration damping effects are greatly reduced, and body fatigue is increased. Therefore, the new cushion can deform after a period of time, lose resilience and lose functional effect.

All other cushions filled with leaves, chaffs, buckwheat, cotton, fibers and the like, and common eyelet waist supports, soft gel cushions, soft silica gel cushions and the like are soft and comfortable, but the support strength is poor, the shape of the product cannot be stable, the product is easy to displace and deform under slight stress, a new lever fulcrum is continuously generated, the lever effect is intensified, more energy is consumed, and the driving fatigue is increased. There is also a kind of inflatable cushion product, which has high surface tension when it is inflated enough, and can transmit the mechanical vibration and impact of the automobile to human body quickly through the tensed surface to bear. When the inflation is insufficient, the surface tension is small, the shape of the product is difficult to stabilize, large-area displacement shaking is easy to generate, the lever effect of a human body is aggravated, and the body fatigue is caused.

The conventional methods for relieving driving fatigue are all methods for making up afterwards, so that the fatigue cannot be synchronously relieved, and an additional action is exerted to increase the physical burden. Common automobile cushion back cushions in the market can not really eliminate or relieve fatigue, waist soreness and back pain in driving synchronously, and the effect is not ideal. For example: (1) a relaxation method comprises the following steps: gymnastics, jogging, yoga, massage, physiotherapy, acupuncture, water bath, sauna, sleep, music, meditation, mind recovery and the like are all methods for making up afterwards, and fatigue can not be synchronously eliminated when driving; (2) the body substances are supplemented, functional beverages, medicines, meals and the like are provided, the body balance can be damaged when people eat more substances, the human body can generate immunity, and the medicine is not good when people eat the food again; (3) various common cushion cloth covers, leather covers, heating pads, air blowing pads, bamboo mat pads, fur covers and the like on the market have the functions of dust prevention, decoration, heating and coolness, and do not have any function of eliminating fatigue; (4) various common massage cushions massage certain parts of a human body by utilizing a motor driving part, still perform the repairing action on the body after fatigue, and additionally impose an external force on the body, thereby increasing the burden of the body; (5) mesh waist rests with various simple shapes support the waist by using the tension of mesh ropes, are very unstable, and are easy to cause serious lever effect due to continuous shaking, so that body fatigue is increased; (6) other sponge waist rests and cushions with various shapes have certain ergonomic design and certain effect, but as shown in figure 2, sponge loose porous structural materials are filled in the sponge waist rests and cushions, but the leverage of human bodies is increased, so that the body is fatigued. As shown in figure 3, the porous structure is easy to collapse to generate permanent deformation, the rebound resilience is poor, the buffering and vibration reduction effects are greatly reduced, and the body fatigue is increased. The new cushion will deform after a period of time to lose resilience and functional effect.

Driving fatigue is generated when a vehicle is driven for a long time, and fatigue driving is caused when the driving fatigue is accumulated too much. Because fatigue driving is harmful to people, we cannot drive fatigue. To reduce the driving fatigue, it is best to eliminate the factors causing fatigue before the fatigue occurs, and to do so simultaneously with the driving. The utility model discloses the driving fatigue who explains indicates normal healthy nature people is driving with normal posture or the fatigue that the in-process produced by bus, contains body fatigue and mental fatigue two parts, and both exert an influence to the human body simultaneously, also can exert an influence alone.

Physical fatigue is mainly directly related to physical environment of substances related to the body, and the physical relationship can be quantitatively or qualitatively researched, so that a specific method can be provided for eliminating factors causing the physical fatigue and effectively relieving the fatigue. Physical fatigue is manifested by soreness of the waist and pain in the back, stiff movement, numbness of the hands and feet, stiffness of the neck, weakness of the limbs, and swelling of the eyes, which are harmful to the spine, strain of the lumbar muscles, soreness of the waist and pain in the back, protrusion of the lumbar vertebral disc, hyperosteogeny, cervical spondylosis, sciatica.

Mental fatigue is very complex, besides being influenced by the physical environment of surrounding substances, the mental, physiological, emotional, memory, drugs, diseases and other factors, and the direct relevance of the influences is fuzzy and objective, and even difficult to qualitatively analyze, which is a world problem. Therefore, the utility model does not discuss mental fatigue. Mental fatigue is manifested by blurred vision, yawning, dozing, mental inattention, reaction retardation, and other harmful factors, such as reaction retardation, lassitude, dull, absent, violent, anxious, nervous, emotional instability, etc.

When the automobile is driven, all the movement and mechanical actions of the automobile which can affect the rider belong to the physical category, and the physiological fatigue of the rider caused by the related physical influences belongs to the modern biological physiology and medical category. We make perfect solution to these relevant factors that lead to driving fatigue, combine modern biology, modern physiology and human engineering and materials science, eliminate or block the factor that leads to driving fatigue from the root, reach and alleviate driving fatigue, the utility model discloses abandon to adopt through extra effect stimulation harm any method of health.

There are four main mechanisms responsible for driving fatigue: human-vehicle resonance effect, human body lever effect, human body inertia effect and the instinct of human body balance danger. The human-vehicle resonance effect can be independently influenced, belongs to mechanical and physical action factors, and influences the whole body of an individual sensitive to the mechanical vibration frequency of the automobile. The body's lever effect induces the natural effects of the body's balance risk, which then synergistically affect primarily the muscle groups associated with the skeleton, particularly along the cervical, dorsal, lumbar, and gluteal regions of the spine. The human body inertia effect can be independently influenced, belongs to the field of physical mechanics, and mainly influences soft tissues and body fluids far away from the protection of bones, particularly the brain, blood and body fluids of the intestines, the stomach and the six fu organs. There are some parts of the body's inertial effects that can induce the natural effects of the body's balance risk. The instinct of human body balance risk is mainly to mobilize related muscle groups to balance the risk considered by the brain, and the lever effect or the inertia effect of the human body is used as a cause to induce the occurrence, and the long-time tension of the related muscle groups can consume a large amount of physical energy to cause fatigue. These four mechanisms are combined to produce a comprehensive effect, which is generated when driving and causes driving fatigue, and are respectively specifically described as follows:

(1) human-vehicle resonance effect: mechanical vibration and impact generated by the automobile act on the human body, so that human tissues respond to the vibration, namely, human-automobile resonance effect.

A vehicle is provided with tens of thousands of parts, each part vibrates in the driving process, various vibrations are mixed and interfered to be superposed to form vibration weighting, so that a vibration source part causing discomfort of a human body is difficult to find, and the vibration is a congenital defect in vehicle manufacturing and cannot be avoided. The rider on the vehicle is subjected to whole body vibrations, and if some of the vibrations have frequencies close to the resonance frequency of the human body, the human body will resonate, and the human body will feel uncomfortable. The sensitive vibration frequency of the human body in the horizontal direction is 0.5-2 Hz, and the sensitive vibration frequency in the vertical direction is 8-12.5 Hz. Modern biomechanical studies suggest that about 4-8 Hz is the human thorax resonance frequency, about 10-12 Hz is the human abdominal cavity resonance frequency, about 2-30 Hz is the head resonance frequency, about 5Hz is the heart resonance frequency, about 18-50 Hz is the eye resonance frequency, about 30Hz is the spine resonance frequency, about 30-40 Hz is the hand resonance frequency, about 4-8 Hz is the hip and foot resonance frequency, about 2-6 Hz is the shoulder resonance frequency, and about 6Hz is the trunk resonance frequency. Due to differences of parts and vehicle use conditions, vibration of each vehicle is different. The differences in weight, body constitution, sensitivity, tolerance, etc. among different persons result in different individuals having different abilities to withstand mechanical vibrations, and even when facing the same vehicle, some persons ride the same vehicle and are prone to fatigue, soreness, back pain, and even nausea and vomiting.

To overcome the human-vehicle resonance effect, the best method is to isolate the human body from the vehicle by using a vibration-buffering material, so as to block the transmission of mechanical vibration and impact to the human body as much as possible and avoid the frequency of sensitive response of the human body. Because the steering wheel, the pedal, the accelerator and the like can transmit vibration, the isolation and blocking can not be achieved completely, but most of vibration can be effectively blocked, so that a driver can avoid the sensitive frequency of automobile vibration.

The automobile seat utilizes the hole-shaped structural deformation of the sponge to effectively buffer the vibration of an automobile, but quite a lot of leaked vibration is transmitted to a human body, and the structural design defect of the automobile seat (as shown in figure 1) often aggravates the human-automobile resonance effect. The soft loose porous structure of sponge class material collapses the destruction and produces permanent deformation easily, and resistance to compression resilience variation has reduced the effect of buffering damping, has aggravated the people car resonance effect, leads to the body fatigue.

(2) Body lever effect and instinct of risk of body balance: the lever effect of human body induces the release of the balance danger instinct of human body, leads the muscle groups of waist, back and hip to be in a tense state for a long time, and consumes a large amount of physical energy to cause body fatigue.

Body lever and lever effect: the human body is an irregular body, a fulcrum can be generated on a supporting surface, natural gravity is generated by partial or whole weight of the human body, and moment is generated by the stress of each point of a contact surface and the difference of stress directions, so that three lever elements in physics are formed, and the human body is pried by the human body, namely a human body lever. Any slight action and change factors of the human body can generate the change of the spatial displacement of the fulcrum, and the acting force can also change, so that the lever of the human body changes more or less. The human body leverage and the additive effect of the human body lever change jointly form the human body lever effect.

Instincts of human balance risk: when people face danger, the instincts of human body balance danger can be obtained by adopting a coping method to counteract the danger so as to achieve safety, and the instincts are instincts of self-protection emergency response mechanism and safety requirement. The balancing is effected immediately after the risk has been created, and it is sought to achieve a considerable force to counteract the risk. The human body balance danger is instinctive, the tool is the human body per se, the most direct, most economical, shortest distance and shortest time principles are followed, and the balance method only can control the muscles per se to run, jump, dodge, tension, tighten the muscles, sweat and the like. Physiologically, the instincts of balancing risk are synergistically accomplished by sensory systems, nervous systems, brain, muscle movements. As shown in fig. 59, the sensory system receives external signals, the nervous system stores and processes the information, the processed information is transmitted to the brain, the brain makes risk assessment and makes final judgment, and the information of the judgment result is transmitted to the muscle by the nervous system to be executed. When the automobile is driven, the signals of space displacement and force change of the waist, the back and the hip of a driver and a passenger due to human body lever effect can be judged to be dangerous signals and need to offset danger due to the instinctive action of human body balance, the brain continuously transmits processing dangerous instructions to a reactor on related neurons through a nervous system, and the reactor controls the cooperative telescopic action of related muscle groups of the neck, the back, the waist and the hip to complete the task of balancing danger. The instinct of human body balance danger in the driving process acts at any time and any place, so that a great number of muscle groups of the waist, the back and the hip are always in a tense state, and the balance of the body is maintained to offset the danger of brain judgment.

The muscle group can consume a large amount of energy when being in a tense state for a long time, so that the internal oxygen supply is insufficient, nutrient substances and body energy are lacked, metabolic waste lactic acid and the like are increased, a large amount of lactic acid is accumulated in the body, potassium ions flow out in the hydrogen and potassium exchange action of cell membranes, and the potassium ions are necessary elements for cell metabolism, so that the muscle cell function is influenced, the muscle fiber contractility is reduced, and the muscle contraction is lack of strength, namely body fatigue. The long-term physical fatigue can cause permanent injury, and the overstrain diseases can cause pathological changes, such as lumbar muscle strain, lumbar disc herniation, scapulohumeral periarthritis and the like.

All articles and methods that increase the leverage effect of the human body increase driving fatigue, such as structural design defects of the car seat itself (as shown in fig. 1), congenital material defects of the car seat sponge (as shown in fig. 2 and 3), eyelet lumbar supports, sponge cushions and back cushions, ultra-soft gel cushions, soft silicone cushions, inflatable cushions, and the like. In life, people think that the softer the cushion the better in wrong thinking area, add one more in case of not going, actually play the opposite role, too much softness produces spatial displacement more easily and aggravates human lever effect, aggravates driving tired waist and back burden, waist soreness back pain buttock pain.

(3) Human body inertia effect: the human body inertia effect is the phenomenon that in the driving process, human body soft tissues and body fluid generate local expansion, local high pressure, mutual friction and kneading damage due to the comprehensive action of external force acceleration, inertia, acting force and reacting force, and the phenomenon that driving fatigue is caused by large consumption of physical energy due to the fact that the soft tissues generate space displacement to induce the human body to balance dangers is released to guide the relevant muscle groups to do stretching movement. Here, the soft tissues mainly include the five viscera, six fu organs, intestines, stomach and brain, and the body fluids include blood and body fluids.

All the motions of starting, accelerating, decelerating, turning, overtaking, braking, backing, ascending, descending, bumping and the like of the automobile can be considered as acceleration motions on physical mechanics, each motion instant segment of the automobile is the superposition of the comprehensive action of three Newton's laws, each motion generating acceleration can generate more or less acting force and kinetic energy impact and can directly influence and act on the body of a driver and a passenger to cause and aggravate driving fatigue, and when the impact energy exceeds the bearing capacity of the human body, the human body can be injured. The effect is systemic, and especially the effect on soft tissues such as viscera organs, intestines, stomachs and brains, blood and body fluid and the like which are lack of bone protection is more obvious. Objectively, individual differences among people are large, bearing capacity, sensitivity and tolerance of the human body are also large, even if the same vehicle is driven to drive the same road, the problem is not caused to the people, and the people are easy to fatigue, waist soreness and back pain and even feel uncomfortable, nausea and vomiting. Therefore, the acceleration acting force and the kinetic energy impact of the automobile can only be qualitatively and hardly studied quantitatively, and only the reduction can be reduced by taking measures and cannot be eliminated.

For convenience of explanation, a simple soft body model is used to decompose complex motion mechanics, as shown in fig. 4, a balloon filled with water is sealed and placed in an automobile to simulate soft tissues such as organs and organs in the human body, the skin of the balloon is similar to the external thin film of the organs, the water in the balloon is similar to the blood and body fluid of the brain, intestines, stomach and six organs, and the motion state of the liquid under the comprehensive action of inertia, acceleration, acting force and reacting force in a sealed flexible container is studied. As shown in fig. 4, A, B, C part of the water is actually a whole liquid, and is artificially and virtually divided into A, B, C parts for convenience of illustration.

Ideally, when the automobile is in a stationary state or keeps moving at a constant speed, the soft model is subjected to an external force F ═ m α ═ 0(N), and the water in the model keeps a stable state, as shown in fig. 4-a. When the car is accelerated forward, as shown in fig. 4-b, the soft body model is forced against part a of the water on the seat back by force F to obtain acceleration a, which produces a velocity v moving forward (newton's second law). The water in part B remains at rest or relatively at rest due to inertia (newton's first law), so that the relatively stationary part B and the part a in accelerated motion are squeezed together (newton's third law), resulting in the parts a and B rising upwards, while the force is transmitted to part B. Part B is forced to gain acceleration, producing a velocity shift forward, which presses against the relatively stationary part C, resulting in part B and part C lifting upward. The water in the model can support the skin to form an arc surface with one high side and one low side due to extrusion expansion, and the side closest to the acceleration advancing direction is low. If the vehicle is accelerating, this high-low arc will continue. When the automobile stops accelerating and keeps a constant-speed linear motion state, the soft model bears an external force F (m alpha) 0(N), and the water in the skin keeps a stable state again as shown in figure 4-a (Newton's first law).

When the vehicle brakes a deceleration movement, the water force F against the seat bottom obtains an acceleration- α, as shown in fig. 4-C, and the water deceleration of the bottom C moves with the vehicle (newton's second law). The upper part of the water B keeps moving forward continuously due to inertia (Newton's first law), so that the part B which keeps the original speed presses the part C which is relatively slow (Newton's third law), and as a result, the part C rolls and rises backward and upward and anticlockwise and the part B also rolls and rises upward and forward, and meanwhile, the acting force is transmitted to the part B. Part B is forced to obtain acceleration-alpha, the speed is reduced, the part B continues to move forwards, and the part B interacts with part A which keeps the original speed to be squeezed, so that part B rolls and rises backwards and upwards in a counterclockwise mode and part A rolls and rises upwards and forwards. The water in the model can be rolled, thrown, extruded and expanded to support the skin to form a cambered surface with a high side and a low side by layer transmission, and the liquid level closest to the acceleration advancing direction is low. The cambered surface with one high and one low continues to keep constant-speed linear motion after the automobile decelerates to a certain speed, or decelerates until the automobile stops, the hydration external force F sum m alpha in the model is 0(N), and the skin reclaimed water can return to and keep a stable state, as shown in fig. 4-a (Newton's first law).

From the above software modeling, it is seen that the speed of motion change of each accessory (including the seat, the seat cushion, the occupant, etc.) in each car always lags behind the speed of motion change of the car acceleration motion (newton's second law), and each car acceleration motion will generate more or less force and kinetic energy impact on the occupant, and the combined actions are superposed together to macroscopically show the dough-like oscillation phenomenon, and the kneading is applied to the soft tissues of the human body, which is very difficult for people to feel. This kind of vibration ravage directly leads to soft tissue and blood bodily fluid to produce local inflation and local high pressure and directly causes the soft tissue impaired, still can guide relevant muscle crowd concertina movement, consumes physical stamina in a large number because the soft tissue produces space displacement and induces the dangerous instinct release of human body simultaneously. The series of complex phenomena are simplified and called as human body inertia effect, and at the moment, the nervous system participating in information transmission is mainly an autonomic nervous system which plays a role autonomously and is not controlled by the will of people. For example, sometimes a driver sits in a taxi, and some drivers frequently accelerate and decelerate, start and brake suddenly, so that the driver is easy to have gastrointestinal discomfort, cramp, pain, head and brain, have a feeling of confusion, even have a feeling of car sickness and vomiting, and the influence of the inertia effect of the human body exceeds the bearing capacity of the human body.

The human body inertia effect cannot be eliminated, but can be reduced, and by the factor of α F/m, the human body inertia effect is reduced. The rider weight mass m is stable and only reduces the resultant force F on the rider. To reduce the resultant external force F, the supporting surface contacting the occupant's body is large and conforms to the body as much as possible to reduce the force per unit area, and the supporting material supporting the occupant's body has excellent and stable cushioning and damping properties to reduce the kinetic energy of the acceleration impact.

In reality, most of car seats have a caudal vertebra and lumbar neutral zone, as shown in fig. 1, the car seats lack powerful support for the body and reduce the support area at the same time, and the combined external force F is increased, namely the inertia effect of the human body is aggravated. Various sponge cushions and back cushions which are used by a driver and a passenger consciously have certain effect on reducing the inertia effect of a human body, but the compression-resistant supporting strength of the sponge is poor and is only 3-15 kilograms, which is far lower than the body weight, the sponge is easy to flatten, the body weight cannot be stably supported, and the buffering performance is greatly reduced. The sponge is easy to collapse to generate permanent deformation, and the buffering and vibration damping performance is also sharply reduced.

In the aspect of application of the ventilation and sweat releasing functions, a common automobile cushion is suffocated and stuffy, the ventilation and sweat releasing functions of the cushion are not realized, and the cushion mainly adopts fabric with good moisture absorption, such as linen fabric, but the back, the waist and the hip are still moist and stuffy when the automobile cushion is driven for a long time. The common cushion aiming at the functions of ventilation and perspiration on the market has unsatisfactory ventilation effect, or has higher installation and use cost and single function.

The most common breathable structures are simply holes made in the cushion fabric, as shown in fig. 5-a; with a through mesh structure, as shown in FIG. 5-b; there is also a raised structure, as shown in fig. 5-c. The ventilation and perspiration functions of the structures are slight and have limited functions. This is because when the damp and hot moisture from human body subsides and gathers in the structure of these cushions, because these through structures are through can not form obvious pressure differential to drive the quick diffusion of reunion moisture, the temperature drop in the process of reunion moisture according to the diffusion of natural speed, condense into sweat. As shown in fig. 5, these through hole structures and protruding structures tend to increase spatial displacement wobble resulting in leverage effects that exacerbate occupant physical fatigue. The moisture content of the damp and hot moisture emitted by the human body is high in density and specific gravity is larger than that of air, the damp and hot moisture is easy to sink, gather and agglomerate, the automatic emitting and diffusing speed is slow, and sweat is easy to condense to soak the body along with the temperature reduction in the diffusing process, so that people feel uncomfortable. The gas diffusion follows the physical principle of diffusion from the high pressure part to the low pressure part, so the key factor of ventilation and perspiration is to form a significant pressure difference on the agglomerated moisture and accelerate the diffusion speed of the agglomerated moisture so that the agglomerated moisture is discharged and diffused into the air before being condensed.

The other type of ventilation structure adopts an electric drive built-in motor to drive a fan to rotate for forced ventilation, solves the problem that the common cushion has no drive pressure, and can effectively ventilate and perspire. However, the fan and motor occupy a considerable amount of thickness space, so that the seat cushion is relatively thick, and the vehicle seat needs to be refitted during use, which increases the installation cost. The driving motor needs to consume the electric fuel of the automobile, and the use cost is also increased. In addition, the cushion has single function, only solves the problems of ventilation and perspiration, and does not solve the problem of eliminating driving fatigue.

The W-shaped curved surface modeling structure is composed of a cushion bottom 12, a cushion triangular area 13 and a cushion backrest 14. The cushion bottom 12 and the cushion triangle 13 integrated into one piece, and the cushion triangle 13 and the cushion back 14 integrated into one piece, form cushion buttock curved surface between the cushion bottom 12 and the cushion triangle 13 simultaneously, cushion back 14 forms the back curved surface alone, as shown in fig. 6 to 18. The back of the cushion backrest 14 is designed to be a plane, is fully attached to the original seat backrest of the automobile, and is used for balancing and dispersing external force transmitted when the automobile moves, and the cushion backrest 14 is designed to be a curved surface which is attached to the physiological curve trend of the spine of a human body when contacting one surface of the human body, so that the contact surface with the back of the human body is increased, the back of the human body can be attached to the back of the human body to the maximum degree when the cushion backrest is used, and the impact of external force and kinetic energy can be reduced to the maximum.

The W-shaped curved surface modeling structure eliminates a caudal vertebra neutral zone and a lumbar vertebra neutral zone, so that the spine and the caudal vertebra part are treaded and powerfully supported, the weight pressure of the human body and the kinetic energy of the combined external force are optimally, reasonably, evenly and dispersedly distributed along the contact supporting surface of the human body and the cushion, and are transferred to the cushion inner core 17 for digestion and absorption. The cushion inner core 17 is made of the special high polymer energy-absorbing environment-friendly material (PDRM material with point-area deformation recovery). Thus, a complete mechanical system for eliminating the driving fatigue is formed.

The cushion back 14 can be adjusted the angle at will, as shown in fig. 10 and 14, because the utility model discloses the cushion inner core embryo 17 of cushion is soft material, and the overcoat is flexible cloth, and the cushion whole body all is pliable and tough state, does not have rigid skeleton, consequently when placing cushion product 1 on seats, chairs, sofas etc. when using, the cushion can be because of the type is situated straight, and is docile to original seat holding surface, what angle it is exactly what angle original seat back is.

The cushion triangle 13 and the cushion bottom 12 form a hip curved surface, completely cover the hip of a driver, enable the pressure center of gravity of the human body to fall at the lowest part of the curved surface, and the pressure is dispersedly transmitted to the peripheral arc surface from the pressure center, the stress of the hip is even and very small, the mechanical function of the cushion is strengthened, the cushion can be kept comfortable even if the cushion is seated for a long time, and the feeling of hip fatigue and pain caused by excessive local stress can not be generated.

The cushion inner core blank 17 is made of a high molecular energy-absorbing environment-friendly Material, which is obtained by a special formula and process of a tackifying resin modified styrene block copolymer and is called a Point area deformation Recovery Material (PDRM for short). The cushion inner core blank 17 is integrally formed in one step, the cushion inner core blank 17 is a complete whole and is not spliced, any frameworks such as metal, plastic and the like do not exist, and the cushion inner core blank 17 has almost all mechanical functions.

The working mechanism of the W curved surface modeling structure of the cushion body 1 is as follows:

(1) before the human body sits in, the cushion is kept in a basically flat state, as shown in fig. 57, because the inner core material of the cushion has excellent form stability, the original form of the cushion inner core blank 17 is kept.

(2) After a human body sits in the cushion, the cushion instantaneously responds to the action of body pressure to generate initial deformation, the bottom 12 of the cushion sinks down and is fit to the buttocks of the human body, and the supporting surface of the back 14 of the cushion generates initial deformation right along the physiological curved surface of the spine of the human body and is perfectly fit to the contact surface of the human body, as shown in fig. 58.

(3) In the use, the biggest deformation of cushion is the initial deformation that the health produced when sitting in and getting up to leave, and deformation is obeyed in the body contact surface when sitting in, and deformation is replied to initial temper when getting up to leave. Because the inner core material has excellent buffering and vibration damping properties, slow rebound and stretching properties and point area deformation recovery properties, the cushion has excellent shape and form stability, and after a body is seated, the deformation generated in the driving process of a vehicle is very slight and is not enough to generate large-area spatial displacement to promote a new human body lever effect. The excellent transient response deformation capability effectively reduces the human body inertia effect, and the fine buffering vibration reduction performance also greatly reduces the human-vehicle resonance effect. The comprehensive synergy of the effects ensures that muscle groups of waist, back and hip of a body are really relaxed and are not tensed all the time, and the ravage caused by the reduction of internal pressure of soft tissues such as brain blood of internal organs and the like is reduced, thereby eliminating or greatly relieving driving fatigue.

The utility model discloses an adopt the automatic exhaust system of vibration gasbag network structural design to utilize when driving each other mechanical action (car inertia effect) that originally just exists between car and the driver and take the place of taking the car and as the drive power of gasbag oscillation, vibrate the extrusion to the damp and hot moisture of reunion, make the damp and hot moisture of the driver and take the place of taking the place of back, buttock in time effectually discharge out, and can not condense into the sweat, reach automatic ventilative perspire.

The structure of the single oscillation air bag 2 is shown in fig. 22, and the single oscillation air bag 2 is the basic unit structure of the automatic air exhaust system which is formed by the hollow vent pipe 5 and the hollow inhalation chamber 4 which are communicated. As shown in fig. 23 and 24, the vent pipes 5 of a plurality of individual oscillating airbags 2 are connected in parallel on the same vent groove 7 to form an oscillating airbag series, and the vent groove 7 may be a shallow groove or a deep groove. One end of the vent pipe 5 is communicated with the bottom of the exhaust groove 7, the other end of the vent pipe 5 is communicated with the air suction chamber 4, the other end of the air suction chamber 4 far away from the vent pipe 5 is open and not closed, and the other end of the air suction chamber 4 far away from the vent pipe 5 is directly attached to the breathable fabric 20 or the breathable base fabric 21 of the cushion outer sleeve 22.

The upper part of the exhaust groove 7 is directly attached to the air permeable fabric 20 or the air permeable base fabric 21 of the cushion cover 22, so that the air inside the oscillating airbag 2 is communicated with the air outside the cushion cover 22, and the air can flow under a certain pressure. The exhaust grooves 7 of the plurality of oscillating airbag strings are communicated with each other and then connected in parallel to form a network structure of the oscillating airbags 2, which is an automatic exhaust system, as shown in fig. 25. The utility model discloses the cushion has two independent automatic exhaust system, is last automatic exhaust system 15 (as shown in fig. 26) and lower automatic exhaust system 16 (as shown in fig. 27) respectively. Fig. 53 shows the sectional state of the upper automatic exhaust system 15 inside the seat cushion core blank 17, fig. 52 shows the sectional state of the lower automatic exhaust system 16 inside the seat cushion core blank 17, and the thickness space of the thinner portion of the seat cushion bottom 12 is not enough to adopt the structure of the oscillation air bag, but the structure of the through hole 6 can be used, as shown in fig. 23-a, fig. 23-c, fig. 24-a, fig. 24-c, fig. 25-a, fig. 25-c, one end of the through hole 6 still needs to be directly communicated with the bottom of the exhaust groove 7, and such a communication structure can extend the oscillation action of the oscillation air bag 2 to influence and promote the gas flow inside the through hole 6.

As shown in fig. 28, the airbag strings can be inserted in a staggered and three-dimensional manner, so that the density of the oscillation airbag 2 is increased by effectively utilizing the space, and the exhaust effect is increased. As shown in fig. 29 to fig. 36, the upper automatic exhaust system 15 and the lower automatic exhaust system 16 of the seat cushion body 1 of the present invention form a complete automatic exhaust system 10 after being alternately staggered and three-dimensionally interpenetrated, and the exhaust system 10 is completely distributed following the W-shaped curved surface structure of the seat cushion. The exhaust grooves 7 are all evenly distributed on the surface of the cushion inner core blank 17, and one end of the air suction chamber 4 of the oscillating air bag 2, which is far away from the air pipe 5, is also all evenly distributed on the surface of the cushion inner core blank 17. As shown in fig. 29 to 53, the upper exhaust system 15 includes 22 transverse exhaust grooves, 33 longitudinal exhaust grooves, 182 oscillating airbags and 137 air-permeable through holes, and the lower exhaust system 16 includes 24 transverse exhaust grooves, 31 longitudinal exhaust grooves, 174 oscillating airbags and 136 air-permeable through holes.

As shown in fig. 37, the space between the airbag strings is completely filled and occupied by the high polymer energy-absorbing environmental protection material (PDRM), which is equivalent to the thickness of each airbag wall 3 is increased to the boundary of the adjacent airbag wall 3, so that the airbag walls 3 have sufficient supporting strength and resilience, and an entity with an automatic exhaust function is obtained. As shown in fig. 39 to 53, the space between each air bag and each air vent groove included in the automatic air vent system 10 is completely filled and occupied by the high molecular energy-absorbing environment-friendly material (PDRM), so that the complete cushion core blank 17 having the complete automatic air vent system 10 is obtained, and the W-shaped curved surface structure and the mechanical system thereof are maintained.

As shown in fig. 56, the utility model discloses because the oscillation gasbag 2 is wide outside wide in the shape like the beverage bottle, and the port of breather pipe 5 and the bottom port of the room 4 of breathing in all directly pastes with ventilative surface fabric 20 and ventilative anti-skidding backer 21 of cushion overcoat 22, this kind of ventilative surface fabric 20 and ventilative anti-skidding backer 21 are loose porous polyester fiber fabric, such structural design can make oscillation gasbag 2 keep certain gas tightness, but can not totally seal, when pressure drive, the inside and outside gas of oscillation gasbag 2 can circulate. The single oscillating air bag 2 has weak oscillating exhaust effect on damp, hot and damp moisture, but after the plurality of oscillating air bags 2 are connected in parallel to form a network structure through the plurality of exhaust grooves 7, the effect of each unit can be complemented and added, and a powerful, continuous and stable automatic exhaust system 10 is formed after synergistic effect. As shown in fig. 29 to 53, the complete vent system 10 comprises 46 transverse vent slots 7, 64 longitudinal vent slots 7, 356 oscillating airbags 2 and 273 vent through holes.

As shown in fig. 56, when the automatic exhaust system 10 for a seat cushion of an automobile is not in use, the oscillating bag 2 of the seat cushion is in a zero-pressure state, and the air inside the oscillating bag is still. When a human body sits on the cushion, the pressure borne by the cushion is increased sharply, the pressure makes the air suction chamber 4 of the oscillating air bag 2 compressed and deformed, the space is reduced, the pressure of air in the air suction chamber 4 is increased suddenly to form pressure difference with the outside, the air in the air suction chamber 4 can be discharged rapidly to enter the exhaust groove 7, and then the air continues to be diffused to the outer sleeve 22 of the breathable fabric, and then the air continues to volatilize and escape to the air.

Because all the motions of starting, accelerating, decelerating, turning, overtaking, braking, backing, ascending, descending, bumping and the like of the automobile are acceleration motions, each motion instant segment of the automobile is the superposition of the comprehensive action of Newton's three laws. In the automobile motion system, the motion change speed of each accessory (including a seat, a cushion, a driver and the like) in each automobile always lags behind the change speed of the acceleration motion of the automobile (Newton's second law), so that each acceleration-generating motion of the automobile generates more or less acting force and kinetic energy impact on the accessory, and macroscopically shows a dough-like oscillation phenomenon, and the complex phenomenon is simply called as an automobile inertia effect. This inertial effect is the source of the driving pressure for the deformation of the suction chamber of the compression oscillation balloon 2. Because the acceleration movement of the automobile is carried out one by one, the compression deformation of the air suction chambers is carried out one by one, the space change of the air suction chambers is also carried out one by one, the air is discharged when the space is reduced, the air is sucked when the space is recovered, and thus the dynamic pressure difference is formed inside the cushion by the vibrating air bag 2. The damp and hot moisture of the back, the waist and the hip of the driver and the passenger is diffused to the air exhaust grooves 7 which are evenly and densely distributed through the loose porous fiber fabric of the cushion coat, and is sucked, discharged, sucked again and discharged … … by the oscillating air bag 2, the damp and hot moisture is continuously disturbed by oscillation, does not settle together and nest together any more, and is quickly diffused and escaped and volatilized into the air before being condensed into sweat, thereby completing automatic ventilation and perspiration. When the cushion is separated after use, the cushion returns to a zero-pressure state, the space of the air suction chamber 4 returns, the pressure difference disappears after air is sucked, and the air in the oscillating air bag 2 of the cushion returns to be static.

Compared with the inner core blank 11 without the automatic exhaust system (as shown in fig. 38), the utility model has the advantages that the weight is reduced by about 20% and the material cost is reduced under the conditions of unchanged apparent volume and unchanged shape and size; the power-driven automobile air bag vibration and extrusion device does not need electric power for driving, has no use cost, does not need to disassemble and install a seat, has no installation cost, and simultaneously utilizes the mechanical interaction (automobile inertia effect) formed by the vibration work of an automobile and the slight fluctuation gravity work of the body of a driver and a passenger during driving as the driving pressure of air bag vibration to vibrate and extrude the agglomerated damp and hot moisture, so that the damp and hot moisture on the back and the hip of the driver and the passenger can be effectively discharged in time without being condensed into sweat, and the purposes of automatic ventilation and perspiration are achieved. The method is physical, natural and environment-friendly, and has no harm to human body.

The utility model discloses cushion W curved surface molding structure, complete automatic exhaust system, polymer energy-absorbing environmental protection material (point area deformation reply material PDRM) three perfect integration, from the material to the integrated design of structure, when having obtained the driving fatigue performance of synchronous elimination, also obtained the performance of synchronous ventilative perspire. The polymer energy-absorbing environment-friendly material (PDRM) has excellent shape stability and support strength, the actual vertical bearing strength even reaches more than 200 kilograms and is far higher than the weight of a human body, and the automatic exhaust system is prevented from being collapsed by the weight of the human body; meanwhile, due to the point-area deformation recovery characteristic of the material, the surface tension is strong, the resilience and recoverability are good, and the repeated compression and resilience of the air suction chamber 4 of the oscillating airbag 2 are guaranteed. Sponge materials used for common automobile seat cushions in the market have poor compression supporting strength, sponge is easy to crush under stress, sufficient mechanical supporting strength and elasticity are not provided to maintain the structural integrity of the oscillating air bag 2, the oscillating air bag 2 and the

exhaust grooves

7 and 8 can be collapsed to be incapable of working normally, and therefore the structure of the automatic exhaust system 10 has no practical application significance if applied to sponge materials.

The inner core blank 17 is made of a special high molecular energy-absorbing environment-friendly Material (PDRM), which is a modified styrene block copolymer (styrene-butadiene-styrene polymer) with tackifying resin and is prepared by a special formula and a production process, and is also called PDRM.
