Description
Technical Field
The utility model belongs to the technical field of the knapsack support, concretely relates to knapsack support with high strength.
Background
The back of the human body is loaded to walk, which is often generated in the aspects of military marching, field survival, mountaineering training, children backpack, labor carrying and the like. In order to resist the external resistance, keep the balance and stability of the body, and adjust the gait and body posture of the person accordingly. If a person carries a heavy load or bears the weight for a long time, a series of injury problems are easily caused. Relevant medical research studies have proved that long-time walking under load-bearing conditions is easy to cause foot blister, stress fracture, lower limb joint pain, back muscle strain, lumbar disc herniation and other injuries. Therefore, more and more students are working on the problems of the influence of different loads on the advancing movement of the human body, the change of the posture of the body after the load, the adjustment and energy consumption of the gait, the comfort performance of the backpack, the buffering capacity of the footwear, and the like, in order to continuously improve the advancing posture, improve the weight bearing capacity of the human body, reduce fatigue, reduce the risk of injury, and design and develop related protective equipment.
In all military operations, soldiers need to carry various weaponry, but the large amount of weaponry also influences the operations of the soldiers, so how to improve the mobility of the soldiers on a battlefield is the key point of military training of all countries. In China, the mobility of soldiers is always the core of the fighting power of our army, and the mobility can be used for obtaining the local force advantage, which is the essence of our army tactics. The typical infantry combat mode is to complete the tasks of blocking, surrounding and pursuing in the process of quick maneuver, and the maneuver in the period is basically quick pedestrian march. At present, in military sports training of various arms, civil soldiers, preliminary services and even college students, weight-bearing marching is one of the projects which must be completed and is the most arduous training subject, and the marching mode usually requires that soldiers carry a large number of weapon loads to walk with high strength for a long time. Sometimes in order to guarantee a fire in assault, the combat unit has to allocate the soldier with weaponry that exceeds the standard, so that the soldier is heavily loaded above the standard. If the soldier needs to hide the whereabouts in complex terrains such as mountains or jungles, the physical strength of the soldier is almost consumed as early as the maneuvering process of battle, and the physical strength of the soldier can not be ensured to be in a good condition in the final battle process, and the continuous battle capacity is not required to be improved.
Research shows that the gait kinematics characteristic change of soldiers is small under light load, the gait characteristic of soldiers under the conditions of medium load and large load is the remarkable reduction of single support time, the remarkable increase of double support time and the remarkable activity amplitude of the hip joint, the knee joint and the forward inclination angle of the trunk are realized.
When the weight is medium and heavy, the step width value is obviously increased, and the step length value is obviously reduced in the marching process. The pace frequency is less affected by marching time and the weight, so the reduction of pace speed under medium and large loads is more caused by the reduction of the step size.
The soldier keeps the balance of the body by adjusting the angle of the trunk and quickly swings forwards to land by swinging the legs, the double-support time is prolonged, the support area is increased, the stability and the step width of the march are improved, and the stability in the transverse direction during the march is improved.
The soldier foot-ground vertical reaction force has a significant relationship with the negative weight. Under medium and large loads, the impact force peak value is increased in significance, the time of the impact force peak value is advanced, the treading force peak value is increased along with the increase of the weight load, the braking force and the driving force are increased along with the increase of the weight load, and the net difference value between the braking force and the driving force is increased along with the increase of the weight load, so that the inner side force value is increased, and the stability of the soldier is reduced in significance under the large load condition.
The exoskeleton is taken as a new hot research object in recent years, and is used for simulating bones, joints and muscles of a human body to provide additional exoskeleton and a power source for the human body, so that the function of enhancing the bearing capacity of the human body is mainly achieved. The study of the structural load bearing system of the exoskeleton is the first step in its development process. The structure bearing system is used as a transmission medium of external load, and can realize the basic function of the exoskeleton. The strength of the exoskeleton bearing structure determines whether the exoskeleton can meet the bearing requirements, and the dynamic parameters are also important design parameters of a hydraulic system connected with the exoskeleton bearing structure.
Therefore, the design is ingenious in conception, accords with human engineering, enables the center of a human body load to move downwards, reduces fatigue, is suitable for bearing a large number of articles and quickly walking, and has the advantages of being high in strength, high in rigidity, stability and the like, and meanwhile, the compression-resistant tensile property, the bending resistance and the tensile strength are high.
