Description

Technical Field

[0001] This invention relates to the field of stage equipment technology, and in particular to performing arts organizations that use bionic limb movement. Background Technology

[0002] As living standards continue to improve, audiences have increasingly higher demands for the quality of artistic performances. Stage props, as an indispensable part of performance equipment, play an important role in the performance effect, and animal props with limbs are a common type of stage prop in performances.

[0003] Existing animal props with limbs are generally flat products or projections of animal images, lacking three-dimensionality and realism. Audiences cannot perceive the performance effects produced by changes in specific scenes, hindering the presentation of scene effects. While some use real animal props, these are fixed and monotonous, unable to perform a variety of movements. Summary of the Invention

[0004] To address the above needs, this invention provides a performance mechanism for bionic swinging of limbs, which has limbs that can be automatically and independently controlled. The structure of each part of the limbs is compact and flexible, and the debugging is simple and easy to implement. The linkage realizes the bionic movements of the limbs and can realize multiple states of bionic linkage postures as needed, such as leisurely walking or vigorous running.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A performance apparatus for bionic limb movement, comprising a trunk, forelimbs on the front of the trunk, and hindlimbs on the back.

[0007] The forelimb, from top to bottom, includes a fore thigh, a foreleg, and a forefoot. The fore thigh and foreleg are hinged together by a first hinge assembly, and the foreleg and forefoot are hinged together by a second hinge assembly. It also includes a first follower link, a second follower link, and a third follower link. One end of the first follower link is hinged to the fore thigh, and the other end is hinged to a first drive rocker. The first drive rocker is hinged to a first hinge seat fixed to the torso. The lower end of the second follower link is hinged to the foreleg, and the other end is hinged to a first cantilever. The first cantilever is fixed to a first fixed shaft, and the first fixed shaft is cantilevered and fixedly connected to a second hinge seat on the torso. The fore thigh is rotatably mounted on the cantilever of the first fixed shaft. The upper end of the third follower link is hinged to the fore thigh, and the lower end is hinged to the forefoot. The first and second hinge assemblies are hinged together by two hinge seats.

[0008] The hind limb, from top to bottom, includes a hind thigh, a hind calf, and a hind foot. The hind thigh and hind calf are hinged together by a third hinge assembly, and the hind calf and hind foot are hinged together by a fourth hinge assembly. It also includes a fourth, fifth, and sixth follower link. One end of the fourth follower link is hinged to the hind thigh, and the other end is hinged to a second drive rocker. The second drive rocker is hinged to a third hinge seat fixed to the torso. The lower end of the fifth follower link is hinged to the hind calf, and the other end is hinged to a second cantilever. The second cantilever is fixed to a second fixed shaft, which is cantilevered and fixedly connected to the fourth hinge seat on the torso. The hind thigh is rotatably mounted on the cantilever of the second fixed shaft. The upper end of the sixth follower link is hinged to the hind thigh, and the lower end is hinged to the hind foot. The third and fourth hinge assemblies are hinged together by two hinge seats.

[0009] In addition, the torso is provided with drive assemblies at the front and rear, respectively, which are pulsatorically connected to the first drive rocker and the second drive rocker. The drive assemblies include servo motors and reducers.

[0010] Preferably, support columns are fixedly installed at the front and rear of the torso, with the bottom surface of the support columns lower than the lowest surface of the forelimbs and hindlimbs. The support columns support the torso and prevent the forelimbs and hindlimbs from interfering with the bottom surface when performing various movements.

[0011] Preferably, the second hinge seat and the fourth hinge seat are fixed to the top of the support column.

[0012] Preferably, there are two forelimbs and two hindlimbs, which are located on the front and rear sides of the trunk, respectively.

[0013] Preferably, the torso, the forelegs and lower legs of the forelimbs, and the hind legs and lower legs of the hind limbs are each enclosed by steel sections to form a hollow truss structure, and the forefeet and hind feet of the forelimbs are enclosed by steel sections to form a hollow frame structure. By covering the torso, forelimbs, and hind limbs with an animal costume, corresponding animal props such as tigers, elephants, and unicorns are created.

[0014] Preferably, the mechanism also includes a load-bearing component, which includes a chassis and wheels at the front and rear bottom of the chassis. The support column is fixed to the chassis, thus enabling the movement of the mechanism.

[0015] Preferably, the chassis is equipped with a steering component on the front side, which enables the mechanism to steer.

[0016] Preferably, a shock-absorbing disc spring is provided between the walking wheel and the walking chassis.

[0017] The advantages of this invention are: 1. It has four limbs that can be automatically and independently controlled. The structure of each part of the limbs is compact and dexterous, and it is easy to debug and implement. It can realize bionic movements of the limbs in a coordinated manner and realize bionic coordinated postures of multiple states as needed, such as leisurely walking or vigorous running.

[0018] 2. The structure is covered with an animal-shaped cover, combined with a load-bearing part that can move and turn, making the structure three-dimensional and realistic, which is conducive to the display of scene effects and allows the audience to have a better performance experience.

[0038] Combination Figure 8-11As shown, the hind limb 30 includes, from top to bottom, a hind thigh 31, a hind lower leg 32, and a hind foot 33. The hind thigh 31 and the hind lower leg 32 are hinged together by a third hinge assembly 34, and the hind lower leg 32 and the hind foot 33 are hinged together by a fourth hinge assembly 35. It also includes a fourth follower link 36, a fifth follower link 37, and a sixth follower link 38. One end of the fourth follower link 36 is hinged to the hind thigh 31, and the other end is hinged to a second drive rocker arm 39. The second drive rocker arm 38... 9 is hinged to the third hinge seat 310 fixed on the torso 10. The lower end of the fifth follower link 37 is hinged to the hind leg 32, and the other end is hinged to the second cantilever 311. The second cantilever 311 is fixed to the second fixed shaft 313. The second fixed shaft 313 is cantilevered and fixedly connected to the fourth hinge seat 312 provided on the torso 10, and the hind thigh 31 is rotatably mounted on the cantilever part of the second fixed shaft 313. The upper end of the sixth follower link 38 is hinged to the hind thigh 31, and the lower end is hinged to the hind foot 33.

[0039] Combination Figure 3 As shown, the torso 10 is provided with drive components 11 at the front and rear, respectively, which are connected to the first drive rocker 29 and the second drive rocker 39.

[0040] Example 2: Figure 1-3 As shown, based on the implementation of column one, the torso 10 is fixedly provided with support columns 12 at the front and rear respectively. The bottom surface of the support column 12 is lower than the lowest surface of the forelimb 20 and the hindlimb 30, and the second hinge seat 212 and the fourth hinge seat 312 are fixed to the top of the support column 12.

[0041] The forelimb portion 20 and the hindlimb portion 30 are each two in number and are located on the front and rear sides of the trunk 10, respectively.

[0042] Example 3: Figure 1-3 As shown, based on implementation column 2, the performing arts organization also includes a load-bearing part 40, which includes a walking chassis 41 and walking wheels 42 at the front and rear bottom of the walking chassis 41, and the support column 12 is fixed on the walking chassis 41.
