Referring to figs. 1 to shown in Fig. 3 a kind of for lower limb exoskeleton robot standing stabilizing mechanism, including the first support machineStructure 1 and the second supporting mechanism 2, first supporting mechanism 1 and the second supporting mechanism 2 are structure and a mounting means left side all the sameRight symmetrical structure, first supporting mechanism 1 and the second supporting mechanism 2 are separately fixed at the two sides of lower limb exoskeleton robot,First supporting mechanism 1 includes anterior part support device 3 and back support device 4, the anterior part support device 3 and back supportDevice 4 is structure and mounting means front and back symmetrical structure all the same, and the anterior part support device 3 is mounted on lower limb exoskeleton machineThe front of device people side, the back support device 4 are mounted on the ipsilateral rear portion of lower limb exoskeleton robot, the front supportDevice 3 includes front fixation kit 31, front limit assembly 32 and front support component 33, and the front fixation kit 31 is precedingPortion's limit assembly 32 and front support component 33 are arranged from top to bottom and are located at the front of lower limb exoskeleton robot side, describedFront fixation kit 31 and front limit assembly 32 are installed on lower limb exoskeleton robot, and the front support component 33 is pacifiedOn front limit assembly 32, a supporting mechanism 1 and the second supporting mechanism 2 are bilateral symmetry, 3 He of anterior part support deviceBack support device 4 is front and back symmetrical structure, is omitted in claim to the second supporting mechanism 2 and back support device 4Statement, the design of above structure is separately mounted to the two sides of robot and front and back and completes to improve the standing support of robotThe stability of standing is fixed support component by fixation kit, be will not influence when lower limb exoskeleton robot is walkedThe walking of robot.
Shown in referring to Figure 1 and Figure 3, the front limit assembly 32 includes pedestal 321, shaft 322, limited block 323 and cardThe side of tight pin 324, the lower limb exoskeleton robot is equipped with 321 mounting groove of pedestal, and the pedestal 321 is bolted onIn 321 mounting groove of pedestal, the pedestal 321 is trapezium structure, and the short side on the parallel both sides of the trapezium structure is located at outside lower limbIn bone robot and its length is less than the depth of 321 mounting groove of pedestal, and the long side on the parallel both sides of the trapezium structure extendsLower limb exoskeleton robot out, the shaft 322, limited block 323 and clamping pin 324 are each attached on pedestal 321, the shaft322 and clamping pin 324 be respectively positioned on the lower section of limited block 323, the clamping pin 324 is parallel close to trapezium structure compared with shaft 322The long side on both sides, spring is equipped with inside the clamping pin 324, and the front support component 33 is stretch rod 331, the stretch rod331 are rotatablely connected with shaft 322, and seat 321 is trapezium structure, are mounted on the stretch rod 331 on pedestal 321 in rotation to groundWhen, angle can be formed with the direction of advance of robot, collide when so as to avoid walking and influence to walk, meanwhile, bottomLimited block 323, clamping pin 324 and pedestal 321 on seat 321 are located at the rotation of stretch rod 331 of the depth limit of mounting groove,It ensure that the stability of stretch rod 331, be equipped with spring in clamping pin 324, at the rotation of stretch rod 331 to ground, spring is drivenClamping pin 324 bounces, and ensure that the stabilization of stretch rod 331, symmetrical anterior part support device 3 and rear portion branch before and after the setting of sideSupport arrangement 4 and symmetrical first supporting mechanism 1 and the second supporting mechanism 2 all around amount to four stretch rods 331,The stretch rod 331 of front prevents wearer from dumping forward, and the stretch rod 331 at rear portion prevents wearer from toppling over backward, and stretch rod331 or so expansion certain angles, can prevent human body sideways.
Shown in referring to Figures 1 and 2, the front fixation kit 31 is fixing clamp 311, and the fixing clamp 311 passes through boltIt is fixed on the front of lower limb exoskeleton robot side, when wearer walks, stretch rod 331 is withdrawn, fixing clamp is stuck inOn 311, the normal walking of wearer will not influence.
Shown in referring to Fig.1, each described stretch rod 331 is scalable secondary structure, in the junction of stretch rod 331Quick Release bolt 3311 is installed, when tearing the opening of bolt 3311 open, can conveniently adjust the length of stretch rod 331, lower limb exoskeleton machineDevice people wearer is usually present certain size difference, and stretch rod 331 can preferably meet requirement of the user to length.
Shown in referring to Fig.1, the bottom of each stretch rod 331, which is bolted, is equipped with a universal wheel3312, when standing, four stretch rods 331 are supported exoskeleton robot, the universal wheel 3312 and ground face contact of bottom,Wearer can be helped simply to be moved, meet wearer's requirement mobile in small space.
Shown in referring to Fig.1, each described stretch rod 331 is all made of aluminum alloy material, and boom 331 uses aluminium alloy materialMatter can effectively reduce the weight of overall mechanism, mitigate the burden of wearer.
When walking, the contraction of stretch rod 331 is placed on fixing clamp 311 lower limb exoskeleton robot, when needs are to standingWhen being stablized, stretch rod 331 is broken into two with one's hands from fixing clamp 311, open Quick Release bolt 3311, stretch rod 331 is adjusted to conjunctionSuitable length retells stretch rod 331 and 322 is rotated around the shaft, when turning to the limit angle of limited block 323, clamping pin 324It bounces under the action of the spring and stretch rod 331 is fixed, at this point, 4 stretch rods 331 have reached firm support effect,It assists human body to stand, when wearer wants walking, by the outside extraction certain distance of clamping pin 324, rotates stretch rod 331, andIt opens Quick Release bolt 3311 to be shortened, finally be placed on fixing clamp 311.The upper only embodiments of the present invention, it is not intended to restrict the invention.To those skilled in the art, the invention may be variously modified and varied.It is allIt should all include in right of the invention in the interior any modification, equivalent replacement, improvement and so on of spirit and principles of the present inventionWithin claimed range.
