Particularly, the utility model has been abandoned the way as the human engineering design basis according to general consensus data, adopts the up-to-date truck driver statistics of following table as design basis.
Table 1: data basis
Last table data display, the general build of truck driver is medium and small partially, and body movement angle and amplitude are generally less than normal, and be generally bigger but head swings up and down amplitude, so operator's compartment can adjust according to related data, comprises that forward sight is wide to dwindle visual field expansion etc. up and down.
Secondly, determine the position of seat in driver's cab: in vehicle, the driver adopts sitting work, and a man-machine important interface is seat.The design of seat and the layout of arranging the driving comfort and indoor other related facility that directly have influence on the driver.Reasonably settle seat, improve the relation between people and the seat,, play crucial effects for create a comfortable safe working environment to the driver.When determining the position of seat in driver's cab, at first to determine the hip point on the seat, i.e. H point (Hip point), it is the interface point of trunk and thigh.
The H point is the bench mark of the seat size relevant with comfort for sitting posture.After chaufeur was adjusted to seat suitable location and taken a seat with the wish of oneself, the parallel motion amount of hip point and the relation between the vertical shifting amount had reflected the front and back regulated quantity of driver's seat.Comfortable H point should be a prerequisite with the unsuitable and fatigue that alleviates when driving, and the angle between the chaufeur health each several part should remain in the comfortable scope.The utility model makes next-door neighbour's seat anterior outer rim in knee under the human body thigh and calf junction, the H point is according to above-mentioned data and mechanics optimization result of calculation, determine to be positioned at vertical 32 cm point inwards of seat leading edge center-point, radius is 3 centimetres forwards, backwards, in the ellipse that left and right sides radius is 2 centimetres.
Determine the position of eyellipse: eyellipse is meant the statistical distribution figure of chaufeur with the eye position of normal driving posture in driver's seat.The photographed data of driver's eyes position is analyzed as can be known, and they submit to two-dimentional normal distribution.And the distribution pattern that waits hundredths is oval.The position of eyellipse, in the fork truck field, approaching more oval coincidence of distribution of ordering with H.
The layout of bearing circle and various hand operation spares: the fork truck field, consider that from the angle of hommization and safety of operation the preferred operations handle is positioned at the driver seat right front.When fork truck travels or during operation, because forward visibility and operating mode constantly change, chaufeur is in tension all the time, at this moment require chaufeur at upper body hardly with under the situation of leaning forward, can be easily steering dish and variously draw, pull out button and handle etc., to alleviate driver fatigue, guarantee to travel and job safety.For this reason, International Standardization Organization (ISO3958) has stipulated that hand is stretched and the interface, and this is a cardinal principle must observing in the design.Hand of driver is stretched and the interface is meant that chaufeur is sitting in the seat with normal posture, is supported on the throttle springboard heel point at pin, and one holds bearing circle, the another hand can stretch and the maximum space interface.Maximum is stretched and self stretch at interface and chaufeur and ability is relevant, and it can be distinguished by various different hundredths and M-F; On the other hand, it is also relevant with the operator's compartment inner structure size.Ergonomics is taken designing requirement when carrying out the driver's seat design to construction machinery and equipment, must consider that sitting posture is to human physilogical characteristic's the influence and the reasonableness of personal weight distribution, simultaneously when having related parameter to select, should coordinate the contradiction between traveling comfort and the manipulation portability, and the contradiction between traveling comfort and the visual effect etc.
Personal weight distribution: human body weight effect pressure on the seat, should consider that the buttocks different parts is producing the pressure that human discomfort can bear in the past, and act on the pressure on the backrest, accomplish reasonable distribution, rather than be evenly distributed.Promptly should pressure outwards be reduced gradually from scapula and two parts of lumbar vertebra.Therefore, the personal weight distribution on the seat cushion should be that the pressure of ischium part is the highest, and long then ischium progressively reduces to the buttocks periphery on every side, up to be tending towards minimum below thigh that the seat cushion leading edge contacts; Personal weight distribution on the backrest should be that scapula and two parts of lumbar vertebra make pressure the highest; promptly with scapula (being equivalent to the height between the 5th～6 thoracic vertebrae) and bustle (being equivalent to the height between 4～5 lumbar vertebraes) as supporting, to keep not easy damaged of bent arc of normal waist and protection lumbar vertebrae.Different with common vehicle, the preferred height of seat of fork truck is below shoulder.
Steering handwheel design: its actuating force should be a foundation with the body biomechanics parameter, select to be convenient to crew-served mostly in, the lower limit capacity data.Usually, steering-wheel effort is 45-100N, the rotation direction of steering handwheel should be coordinated the ripple that there is suitable finger-type at steering handwheel and the position that contacts of finger mutually with the variation of vehicle heading, it is oval or circular that cross-sectional plane should be, the anthropometry index wantonly suitable to guarantee to handle, that the firm steering handwheel size of gripping meets limb action, steering wheel diameter is the 330-600 millimeter.
Steering handwheel should be arranged in the optimal region of operator's saddle the place ahead, i.e. staff activity is the sensitiveest, the operation zone that accuracy is the highest, the visual field is best.The design of braking footrest brake pedal is based on human body lower limbs size and mechanics parameter.The fork truck brake pedal is the pin hanging type, and shape adopts the rectangle plane plate.Pedal and ground-surface optimum inclination angle are 30 degree, and the comfortable angle of sole and shank should be the 87-95 degree during operation, and angle is the 105-135 degree between thigh and calf.The suitable actuating force of stretcher is 80-400N, and starting resistance is 35-45N, and braking footrest grade braking treadle effort is less than 600N.Brake pedal is arranged in the right crus of diaphragm maneuvering area, to satisfy the operation requirements that actuating force is big, speed is fast and accuracy is high.
Various instrument and signal indicator, the equidistant eyes of instrument carrier panel dead ahead are the 350-780 millimeter on the fork truck.The sight line of plate face upper limb and the angle of horizontal line of sight are not more than 10 degree, and the sight line of lower edge and the angle of horizontal line of sight are not more than 45 degree, and instrument carrier panel and driver vision meet at right angles.Because the people operates under normal sitting position, head generally omits nature and leans forward, so the corresponding inclination of instrument carrier panel, instrument carrier panel and ground-surface angle are the 60-75 degree.Instrument on the instrument carrier panel is arranged according to the visual movement rule, and the most frequently used, topmost instrument and signal indicator come the optimum vision area in the 3 degree scopes of center, the visual field as far as possible.General instrument and signal indicator come in the visual field of 20 to 40 degree, take into account the harmony with operating control simultaneously.Seat upper portion, clear space height should be not less than 1 meter, and top is provided with the protection ceiling.
