In living nature, through the evolution in 3,500,000,000 years and struggle for existence, produced much can accessible motion on various environmental surfaces the master-hand, such as gecko, spider, snake, fly and locust etc.By the nature survival of the fittest in natural selection and long-term evolution, they have had the adaptability of height to natural environment, and motion function and organ structure are more perfect more than the machinery that the mankind once made.In field of engineering technology, the Bionics application product is more and more, falls resistance bionics plow moldboard, bionical walking wheel etc. such as dehesion, has all produced very good effect in practical implementation.

Ostrich originates in Africa and the larger area of the Arabian Desert temperature difference, mainly lives in spacious desert region and dry prairie without tree.Ostrich belongs to the ratite bird, breastbone is flat does not have a keel projection, clavicle is degenerated, forelimb is evolved into wing, degenerated and can not circle in the air, strong but hind leg is strong, in the sand ground environment, have magical sane, lasting and high speed ability to run, being genuine race top-notch player in the birds, also is the two legs animal that the land is run the most soon.The more husky ability of the excellence of ostrich is many-sided coefficient results such as body structure, organ, neck, wing (forelimb) and hind leg (leg and foot).Wherein, ostrich foot carrying ostrich body weight directly contacts with sand ground and participates in moving, and the effect in more husky process is most important.The ostrich foot is two toes (III, IV toe) only, interior toe (III toe) is larger, has hard pawl, outer toe (IV toe) is flukeless then, the meat pad that cutin is arranged below the toe, high resilience also can be heat insulation, and these special constructions are that ostrich has the key factor that superpower anti-depression and antiskid move performance enough when walking and running in conjunction with the peculair motion mode.Take ostrich foot structure and more husky mechanism as theoretical foundation, adopt the engineering bionics technology, development is applicable to the long-term on foot Bionic desert-through staff of activity such as travelling in the desert Environment, exploration and exploration and has practical significance and application prospect.

The present invention is take ostrich foot structure and more husky mechanism as theoretical foundation, adopts the engineering bionics technology, and design is applicable to the long-term on foot Bionic desert-through staff of activity such as travelling in the desert Environment, exploration and exploration.

The present invention is by the cane body, cane holder and cane point form, the cane body is screwed onto in the top tray of top of cane holder, the cane point is coniform, the cane point is screwed onto in the lower tray of below of cane holder, the cane holder is by top tray, many upper bracket bars, many carriage bar, return spring, lower tray and two flexible coverings form, return spring is fixed between top tray and the lower tray, the upper end of many upper bracket bars is hinged on the outer rim of top tray, the lower end of the carriage bar identical with upper bracket bar quantity is hinged on the outer rim of lower tray, the upper end of carriage bar is hinged on the lower section of corresponding upper bracket bar, the periphery of many upper bracket bars covers flexible covering, and the periphery of many carriage bar covers flexible covering.

Described flexible covering is by sandwiched high elastic rubber in the middle of two layers of industrial cloth, forms with suture.

Described cane is socketed to form by sleeve pipe as multi-section structure.

The invention has the beneficial effects as follows:

The present invention uses the superior function with anti-depression and antiskid in the desert, effectively improved the handling capacity of user at desert middle-long distance pad it, has really played the effect of more husky assistive device.Bionic desert-through staff enters husky in the desert and goes out all to have obvious technique effect in the husky process.When the cane head of more husky cane is divided into sand, the lower tray of cane holder and cane point at first sand, increase along with load capacity, the cane holder overcomes the reaction force of spring, apex angle α increases gradually, and upper carriage bar angle β reduces gradually, and the surface of impelling carriage bar to form progressively contacts with Shamian Island, and carrying certain weight, the part inner surface that last upper bracket bar forms (outstanding part outward) also all contacts with Shamian Island; Along with the continuation of lower tray is risen, after 60 ° of apex angle α values of exceeding the maximum, will reduce a little, the upper bracket bar also can inwardly shrink a little, plays the effect of fixing the sand, until lower tray moves to extreme position, is in complete loaded state.This moment, the load by the transmission of cane body almost all put on the cane holder, acted on each position that cane holder lower surface contacts with Shamian Island.At this moment the cane point belongs to low load or zero load condition, and the cane point can not continue to sink, and the sand around the cane point constantly tightens under the effect of cane holder stand under load, has prevented that effectively the cane point from rocking and slippage.When the cane head of more husky cane is told sand, along with cane is born cancelling of lotus, the cane holder is under the reaction force acts of spring, upper bracket bar outward outstanding part formation at first separates with Shamian Island with the surface of Shamian Island contact, carriage bar forms with the surface of Shamian Island contact separates with Shamian Island thereupon, and the surface that lower tray contacts with Shamian Island and cane point leave Shamian Island at last.This step by step mode of unloading has reduced the contact area of cane head part and sand ground gradually, and the cane point all is turbination with upper bracket bar tip in addition, has effectively reduced the shock vibration of cane head part to sand, has prevented cane head part generation " choosing sand " phenomenon.

See also Fig. 1, Fig. 2 and shown in Figure 3, the present invention is by cane body 1, sleeve pipe 2, cane holder 3 and cane point 5 form, cane body 1 is multi-section structure, be socketed to form by sleeve pipe 2, cane body 1 is screwed onto in the top tray 6 of cane holder 3 tops, cane point 5 is coniform, cane point 5 is screwed onto in the lower tray 12 of below of cane holder 3, cane holder 3 is by top tray 6, eight upper bracket bars 9, eight carriage bar 11, return spring 10, lower tray 12 and two flexible coverings 4 form, return spring 10 is fixed between top tray 6 and the lower tray 12, the upper end of eight upper bracket bars 9 is hinged on the outer rim of top tray 6 by bolt 8 and nut 7, the lower end of eight carriage bar 11 is hinged on the outer rim of lower tray 12 by bolt 8 and nut 7, the upper end of carriage bar 11 is hinged on the lower section of corresponding upper bracket bar 9 by bolt 8 and nut 7, the periphery that the periphery of eight upper bracket bars 9 covers 4, eight carriage bar 11 of flexible covering covers flexible covering 4.

As shown in Figure 3 and Figure 4, described flexible covering 4 is by sandwiched high elastic rubber 42 in the middle of two layers of industrial cloth 41, sews up with suture 43 to form.

Use state of the present invention is as follows:

1, original state: such as Fig. 1 and shown in Figure 5, the lower tray 12 of cane point 5 and cane holder 3 is touched husky, the top of cane point 5 inserts husky surface, simultaneously, the lower tray 12 of cane holder 3 has just touched husky surface, and this moment, return spring 10 did not also have stressed, whole cane holder 3 is in original state, at this moment, α=30 °, β=120 °.

2, carrying intermediateness: as shown in Figure 6, lower tray 12 is on the same straight line with carriage bar 11, the apex angle α value of reaching capacity, and this moment, cane holder 3 and Shamian Island contact area reached maximum, at this moment, α=60 °, β=30 °.

3, plastic stage: as shown in Figure 7, along with load increases, lower tray 12 constantly moves upward, until return spring 10 reaches capacity, cane holder this moment 3 is in the ultimate bearing state, and from the carrying intermediateness, apex angle α just is less than 60 degree, so that upper bracket bar 9 inwardly shrinks, play the effect of fixing the sand of shrinking.Institute contains sand and measures and reach maximum in this moment cane head, at this moment, and α=55 °, β=14 °.

Operation principle of the present invention is:

Sand in the desert is soft, mobile large, responsive to the active force reaction, when cane holder 3 rigidly connects tactile Shamian Island, cane point 5 has inserted in the sand, cane point 5 extruding sands spread towards periphery, and the active force that lower tray 12 overcomes return spring 10 moves upward, and sand is compacted under the reaction force of lower tray 12 simultaneously.Along with lower tray 12 contacts husky continuous increase of measuring, sand then flows out around lower tray 12, enters in the surface of carriage bar 11 formation.Along with the continuation of sand amount increases, sand is wanted to flow out outside the cane head, but because the surface that upper bracket bar 9 outer outstanding parts form is intilted, so sand can only be accumulated in the cane holder 3, and the sands in the cane holder 3 are compacted gradually.After the apex angle α value of exceeding the maximum, inwardly shrink on the surface that upper bracket bar 9 forms, the sand in the contraction process in the further extruding cane holder 3.When entering plastic stage, the active force that is transmitted by cane body 1 almost all puts on the sand in the cane holder 3, and the sand of bottom also produces active force to the sands in the cane holder 3 simultaneously, thereby the sands in the cane holder 3 are formed the up and down effect of extruding.By around, the up and down contraction extruding of all directions, the sands in the cane holder 3 form " transient state solid ".This moment, bearing capacity acted on one large-area " transient state solid ", and cane point 5 has penetrated in this " transient state solid " simultaneously, thereby reached the effect of anti-depression and antiskid, and bearing capacity also increases several times than tradition travelling cane.
