Detailed description of the invention
Be described in more detail below in conjunction with the technical scheme of detailed description of the invention to this patent.
Refer to Fig. 1-3, a kind of bionical flexible spinal structure of two degrees of freedom of quadruped robot, comprise forerunner 1, flexible spinal and rear-guard 7, described flexible spinal comprises spring 4, rope driving device and the joint transmission means be formed by stacking by multiple rotating mechanism, described rotating mechanism comprises rotating table 3 and fixed frame 5, described rope driving device comprises rope 2 and wheel disc 6, described rear-guard 7 is arranged on the right side of forerunner 1 by joint transmission means, described wheel disc 6 is provided with multiple, wheel disc 6 is arranged on the inside of forerunner 1 and rear-guard 7, described rotating table 3 and fixed frame 5 are equipped with multiple, rotating table 3 is connected by fixed frame 5, described spring 4 is arranged between two rotating tablees 3, when spring 4 ensures passive movement, the anglec of rotation of each layer is comparatively even, also serve certain buffer action simultaneously, described rope 2 is through spring 4, the one ends wound of rope 2 is on wheel disc 6, the other end of rope 2 is fixed on forerunner 1 or rear-guard 7.
Two wheel discs 6 are respectively provided with in described forerunner 1 and rear-guard 7, two described rotating tablees 3 are equipped with four springs 4, described rope 2 is provided with four altogether, wherein one end of two ropes 2 is wrapped on the wheel disc 6 in forerunner 1 respectively, the other end is fixed on rear-guard 7, one end of other two ropes 2 is wrapped on the wheel disc 6 in rear-guard 7 respectively, and the other end is fixed on forerunner 1.
Described joint transmission means is formed by multi-layer rotating Mechanism Combination, whole device passive movement, and its power is provided by rope driving device, and rope driving device control mechanism realizes rolling and pitching two degree of freedom, described rope driving device comprises the identical wheel disc of shape 6 and two groups of ropes, wheel disc 6 is each in forerunner 1 and rear-guard 7 arranges two, two groups of ropes are made up of a pair rope respectively, four rope difference one ends wound are on wheel disc 6, then through joint transmission means, the other end and forerunner 1 or rear quarters 7 affixed, every a pair rope 2 realizes take-up and unwrapping wire by wheel disc 6, thus control mechanism carries out rolling and pitching, described joint transmission means two ends respectively with forerunner 1 and rear-guard 7 affixed, himself is formed by multi-layer rotating Mechanism Combination, every layer of rotating mechanism can realize 2 direction motions, described spring 4 is arranged on joint transmission means between layers, between often two-layer, four springs 4 are set, two groups of ropes of rope driving device pass from its centre, each fixed frame 5 connects one end of two rotating tablees 3, realize the rotation of both direction respectively.
