Description
Technical field
The invention belongs to backpack support technical field, and in particular to it is a kind of with high intensity backpack support bearing equipment and
The manufacture craft of its backpack support.
Background technology
Human body back walking with load, is frequently experienced in military march, field survivorship, mountain-climbing training, children's knapsack and labor
In terms of dynamic carrying.This walking manner, human body is acted on from outside imposed load, changes the position of centre of body weight, in order to
Resist this additional drag effect, keep the balance and stably of body, the gait and body gesture of people necessarily can also make corresponding
Adjustment.If it is overweight that human body bears weight, or undertake weight for a long time, then a series of damage problem is easily caused.It is related
Medical survey is studied it has been proved that walked for a long time under loading conditions, be easily caused pin get blister, stress fracture, under
Limb arthralgia and muscle of back are pulled, waist dish outstanding equivalent damage one.Therefore, increasing scholars start to be directed to grinding
Study carefully the different influences born a heavy burden and brought to human body traveling motion, the change of body gesture after heavy burden, the adjustment of gait and energy expenditure,
The problem of in terms of the comfort property of knapsack, the buffer capacity of footwear, to continuously improve traveling posture, improve the negative of human body
Beijing South Maxpower Technology Co. Ltd's power, reduces fatigue, reduces damage risk, and design the protective gear related to exploitation.
In all military operations, soldier will carry miscellaneous weaponry, but substantial amounts of weaponry
The action of soldier has been had influence on, therefore, the maneuverability of soldier afield how has been improved, is the emphasis of various countries' military training.
In China, the mobility of soldier is always the core of my army's fighting capacity, and local preponderance of forces is obtained with maneuverability, is my army
The marrow of tactics.Typical infantry's combat mode, is exactly during fast reserve, to complete blocking, surrounding, pursuing and attacking for task,
And it is motor-driven during this, it is exactly quick foot march substantially.At present in all arms, people's militia, reserve duty even students in military body
Educate in training, march of bearing a heavy burden is one of the project that must complete, is also most arduous training subject, and this march mode often will
The scholar that provokes battle carries the walking that substantial amounts of weapon load carries out long-time high intensity.Firepower, combat troop are assaulted sometimes for guarantee
Have to soldier's dispensing beyond the weaponry of standard, cause soldier's load to be much higher than standard.If in mountain region or
Complicated landform as jungle, adds whereabouts to be hidden, and the muscle power of soldier is similar with regard to what is consumed during combat manoeuvre
, usually it cannot be guaranteed that in last course of battle, physical efficiency is in good situation, should not more put forward the ability of lasting operation.
Research shows, when gently bearing a heavy burden, and soldier's gait kinematics changing features are smaller, and under medium heavy burden and big loading conditions
Soldier's gait feature is the reduction of single supporting time conspicuousness, the increase of dual-gripper time conspicuousness, bones of the body joint, knee joint and body
Dry forward leaning angle movable amplitude is notable.
When medium heavy burden and big heavy burden, step width value conspicuousness increase, single step long value declines significantly during march.And walk
Frequency is influenceed smaller by the march time, is influenceed also smaller by loading weight, therefore is walked in the case of medium heavy burden and big heavy burden
More decline of speed is due to caused by step value declines.
Soldier is by adjusting trunk angle, to maintain the balance of body to be landed by rapidly forward swing of leading leg, and increase is double
Supporting time increases Area of bearing simultaneously, improves the stability step width increase of march, in horizontal stability when improving march.
The vertical reaction force in soldier foot-ground has notable sexual intercourse with loading weight.Under medium heavy burden and big heavy burden, impact force
Peak value conspicuousness increases, while impact force peak value time of occurrence shifts to an earlier date, pedals soil fertility peak value and increases also with the increase of loading weight
Brake force, motive force increase with the increase of loading weight, and brake force is with motive force net difference value with the increase of loading weight
Show that soldier reduces in big heavy burden situation stability inferior conspicuousness in outside forces value rise in increase trend.
Ectoskeleton is as popular research object emerging in recent years, by simulation human skeleton, the joint of simulating human body
And muscle, it is that human body equips extra ectoskeleton and power source, the main function of playing enhancing human body carrying.The structure of ectoskeleton is held
The research of loading system is the first step of its development process.Structural bearing system can realize dermoskeleton as the transmission medium of external applied load
The basic function of bone.The intensity of ectoskeleton bearing structure determines that can ectoskeleton realize its bearing requirements, and its kinetic parameter is also
It is the important design parameter of connected hydraulic system.
Therefore, design one kind is skillfully constructed, and meets ergonomics, human body heavy burden center is moved down, and reduces fatigue, is adapted to the back of the body
That bears large numbers of items and quickly walk bears equipment with high intensity backpack support, and backpack support has super-low resistance, Gao Gang
Property and the advantages of stability is strong, meanwhile, its resistance to compression tensile property, counter-bending and tensile strength are high.
The content of the invention
The purpose of the present invention is to overcome the deficiencies in the prior art novel there is provided structure, is skillfully constructed, meets ergonomic
Learn, human body heavy burden center moves down, reduce fatigue, be adapted to bear large numbers of items and quickly walk has the knapsack branch for bearing effect
