Description
Technical field
The present invention relates to a kind of strong point temperature based on bimetallic plate and memorial alloy effect and become adjustable type seat.
Background technology
The meaning of seat is as people provide a kind of body support to keep the device of sitting posture.Seat is the meaning of seat, and chair is then the title that one is called the trees of " Chinese catalpa " at first.The title of chair, first appeared in the Tang Dynasty, imports the Hu bed in the north into when image then will pass up to Chinese Wei.After the Tang Dynasty, the use of chair increases gradually, and the title of chair is also widely used.
Seat can be divided into airport seat, automotive seat, bus seat, home seating, dining room seat, child safety seat and Relaxing chair etc. by purposes difference, and then can be divided into aluminum alloy seat, corrosion-resistant steel seat, iron seat, Wooden chair and other materials seat etc. according to material.Seat often needs to possess different functional requirements because of the difference of its purposes, such as family and Relaxing chair be first demand fulfillment traveling comfort requirement often, dining room seat then tends to again first consider traveling comfort and novel outward appearance, and auto use chair then needs first possess good safety.In the primary stage of economic development, required by people often just have the above-mentioned basic function of seat, along with social progress, the expectation of high-end user to seat is also more and more higher, except basic functional requirement, the traveling comfort of seat, novelty, health, economy and safety etc. often also become primary demand.
At automotive field, although namely establish the guilding principle of first developing auto-industry at the beginning of founding the state, very over a long time, the auto-industry of China belong to the transportation means meeting shipping and carrying function substantially.After the nineties, along with the raising of living standards of the people, private car starts to enter the lives of the people, and popularizing along with private car, people are no longer satisfied with the requirement of some basic functionalities to the understanding of vehicle, the safety of driving, the traveling comfort of seat, the indexs such as the novelty attractive in appearance of interior trim become top-priority problem when choosing vehicle gradually, after 2000, relatively rich stratum, start the commercial vehicle selected seat comfort more and more and there is good riding experience, and there is wide open and become the first-selection of a lot of young and middle-aged car race by large space SUV and MPV etc. of performance especially.
It is generally acknowledged, along with the development of automobile industry, auto use chair mainly experienced by following several development phase generally:
1) the blank stage.Before 2000, auto use chair just meets the basic function sat, and there is no special design, similar on armchair structure, and kind is few, and quality is also general, producer and dealer is few but profit is higher.
2) early stage of development.During 2000-2002, seat is without design, and quality is general, but industry demand increases to some extent, and production quantity increases, and profit declines to some extent, but still considerable.
3) the fast-developing phase.During 2002-2005, businessman starts to pay close attention to seat design theory, and high, normal, basic differentiation has also appearred in quality, and businessman's quantity rolls up, large on a small scale not etc., product profit is gradually thin, has occurred professional seat brand.
4) stable growth stage.After 2005, seat starts to emphasize product design more as commodity, and obviously, profit is also obviously broken up in quality differentiation, and closing down frequently and newly opening appears in producer, and brand operation starts strengthening, has occurred the retail trader run in scale in industry.Since 2010, seating industry market presents expensive goods and low cost products and the situation of depositing, and professional brand is in occupation of most of market, and occurred the associating of large-scale dealer and producer and integrated trend, trade monopoly blank is faded in.
Seat becomes the key factor of choosing vehicle because of it on the impact of riding experience, department's multiplication ring border narrow space, extending space is limited, the mood of meeting severe exacerbation driver and crew when taking for a long time, and also can affect physical and mental health to impact sanguimotor below buttocks due to sitting, if long-time driving regularly, may various diseases be suffered from.Such as, buttocks poor blood circulation, easily causes buttocks sultry, especially unfavorable to male sex Jiankang, and easily brings out the virile diesaes such as buttocks furuncle and prostatitis; Because rectum anal tube venous return is obstructed, easily make the blood stasis of blood long-pending generation hemorrhoid, below shank, sometimes also there will be the cool sensation gone up painful of pin; In narrow and small motor space, because health can not normally be unfolded for a long time, entire weight is all pressed in vertebrae bottom, pressure bearing face is distributed uneven, and be easy to cause Musculoskeletal system disease, the lighter takes on waist and leg ache, heavy then cause disc herniation, the diseases such as scapulohumeral periarthritis.
Existing auto use chair can be accomplished safe, comfortable, durable, attractive in appearance mostly as far as possible on the basis of comprehensive cost performance, and accomplishes that technique is meticulous as far as possible, is easy to install manipulation, is easy to safeguard, and meets environment protection requirement.The high-end seat of part has also set up additional function and the air bag devices etc. such as heating temperature adjustment, automatically controlled posture adjustment, electric massage further.Generally speaking, the requirement that automotive seat should meet rational deployment, profile meets ergonomic designs, have regulating mechanism, have good vibration characteristic and five aspects such as safe and reliable.Along with the difference of functional configuration, the price of auto use chair also has larger difference, and the average price of general car seat is about 850-1050 dollar, and middle-grade car is about 1400-1600 dollar, and the price of high-grade seat usually can more than 2000 dollars.Concerning most of car, seat is parts all more expensive than change speed gear box, chassis and vehicle body.
In recent years, Domestic Automotive Industry development is swift and violent, and this provides the wide market space for automotive seat industry.2010, Chinese automobile production and marketing was respectively 1826.47 ten thousand and 1806.19 ten thousand, increases by 32.44% and 32.37% on a year-on-year basis.Wherein, manned vehicle production and marketing 1389.71 ten thousand and 1375.78 ten thousand, increase by 33.83% and 33.17% on a year-on-year basis.Commercial vehicle/comm..vehicle production and marketing 436.76 ten thousand and 430.41 ten thousand, increase by 28.19% and 29.90% on a year-on-year basis.2013 and increasing degree continuation held stationary situation in 2014, estimate within 2015, to keep inertia to increase, automobile sales volume will break through 3,000 ten thousand when the time comes.As the vitals of car load, the sales volume of automotive seat and the volume of production and marketing of car load closely related, its industry development space and market outlook by luxuriant be considerable.
Structurally, auto use chair mainly comprises physical construction, electronic control system, drive motor and sensor.Wherein physical construction is the basic components of support human body weight, enough Rigidity and strengths should be had, physical construction generally comprises spring damping cushion, backrest, side back support and several part of resting the head on, electronic control system is the control system of seat, be responsible for the data of pick-up transducers, and instruction can be manipulated accordingly according to the demand execution of user, drive motor is performer.
In automotive seat standard; motor-vehicle seat system be automotive occupant take instrument; it not only should be able to grantee's body weight; also should be able to bear the impact in the repetitive operations such as vehicle start, acceleration, braking and collision case, be one of important safety parts automobile being protected passenger's safety simultaneously.Therefore, both at home and abroad the formulation of motor-vehicle seat system safety rate is also all paid much attention to.China formulated the relevant criterion of automotive seat aspect in 1993, along with the develop rapidly of Domestic Automotive Industry, the portion of techniques index of this standard and test method day by day cannot meet the general requirement to car load passive security performance, and also there is a big difference with developed country in the world existing automotive seat standard.On the basis of old edition national standard, carry out revised after 2003, thus made this standard more adapt to the needs of Domestic Automotive Industry development.
At technological layer, the critical component of auto use chair mainly comprises seat motor, slide rail and recliner, and the relevant additional function strengthening traveling comfort then comprises Seat Lumbar Support, seat heating function, seat massage function, ventilated seating function and seat memory function etc.Wherein some belongs to functional design for this, related industry technology is comparatively ripe, there is no special technical barrier, such as seat heating function, seat massage function and ventilated seating function etc., some then belongs to comparatively advanced core technology, as seat motor, slide rail, recliner, and seat memory function, the technical merit of these parts and function directly affects index such as seat manipulation smoothness and reliability etc., because commercial seat is to the rigors of mechanism design, seat motor often requires to realize larger horsepower output under less volume, but also higher antinoise and anti-vibration defect level will be had.In seat safe performance indexes, seat slide needs the quiet pulling force bearing more than 24kN, and will ensure that slide rail wants stress equalization when being subject to the power of all directions such as malleation and layback, can not produce disabler.This just needs to design slide rail cross section scientifically and rationally, and particularly slide rail raw MAT'L itself needs tensile strength to reach more than 600MPa.The core technology of recliner is parameter designing and the manufacture of profile of tooth, internal tooth and external tooth are the main force parts of recliner, tooth profile degree, flank of tooth quality (tooth-face roughness, flank of tooth resistance to abrasion, flank of tooth strength at repeated alternation), dedendum strength are all had higher requirements.At present these gordian techniquies still rest in the foreign capitals such as Bosch, Bo Ze, Fo Jiya, Jiang Sen, happy be rich and joint venture's hand mostly.
On the whole, domestic and international auto use chair reaches higher level at technological layer, but some aspect still exists some difficulties, specifically comprises:
1) drive environment space narrow and small, health legs and feet not easily stretch, and long-term driving endangers reproductive system and lower body health, although massage mechanism can be adopted suitably to alleviate, massage mechanism is complicated, and cost is higher, for driver, also there is distractive problem;
2) vehicle body space is limited, space shared by seat physical construction self should be little as far as possible, and traditional Member Welding technique is difficult to fully ensure seat intensity, and Bolt Connection is compact not, also may get loose after Long-Time Service, need the operational space that reserved seat loads and unloads in addition, and attractive in appearance not.
3) the personalized customization problem of seat, bone and the sitting posture of each driver and crew are all not quite similar, and desirable seat should be able to realize the self-adaptative adjustment of seat mechanical component to skeleton, thus make driver and crew be in sitting posture state the most comfortable.
In addition, seat is also a problem when emergency brake state to the self-adaptative adjustment of force of inertia, although existing correlative study report at present, the product of maturation not yet emerges.
