[0063] Embodiment 2:
[0064] The utility model discloses a four-bar linkage mechanism 11 is combined with the design of introducing double triangle trapezoidal structure 17, and the stability of the stability high bionic mechanical deer four limbs structure 2 that is conducive to the interaction with children is improved obviously. The design utilizes the inherent stability characteristics of geometric structure, and through ingenious structural design, the bionic mechanical deer that is conducive to the interaction with children in high stability can maintain stable, reliable performance under various working conditions. For example: in the bionic mechanical deer that is conducive to the interaction with children in high stability, double triangle trapezoidal structure 17 is composed of first connecting rod 111, second connecting rod 112, third connecting rod 113 and fourth connecting rod 114. This structure utilizes the geometric stability of triangle, and the trapezoidal gap 19 formed by misplacement is further enhanced the overall rigidity and stability of the structure. The specific implementation is as follows:
[0065] First triangle 20: composed of first connecting rod 111, second connecting rod 112 and skeleton structure 1. This triangle provides preliminary structural support, ensuring the stability of four limbs structure 2 during movement.
[0066] Trapezoidal gap 19: formed by misplacement design of third connecting rod 113 and fourth connecting rod 114, enhancing the flexibility and buffering capacity of the structure. This design allows effective stress dispersion during movement, reducing vibration transmission when walking on complex terrain.
[0067] Second triangle 21: trapezoidal gap 19 and first triangle 20 work together to form a larger triangular structure. This double triangle structure further enhances the stability of the bionic mechanical deer four limbs that is conducive to the interaction with children in high stability by strengthening the overall rigidity, especially when running on uneven ground or under high load.
[0068] In addition, the four-bar linkage mechanism forms a self-locking function, specifically, the four-bar linkage mechanism 11 through reasonable geometric design, so that the bionic mechanical deer that is conducive to the interaction with children in high stability can realize self-locking function in static state. The realization of self-locking function depends on the combination of double triangle trapezoidal structure and four-bar linkage mechanism, so that the four limbs structure can remain stable when static, and will not loosen or sway due to gravity or external impact.
[0069] And the cooperation between first connecting rod 111 and second connecting rod 112: through the connection of rotating shaft 81 and skeleton structure 1, first connecting rod 111 and second connecting rod 112 form a stable triangular structure during movement. When the bionic mechanical deer that is conducive to the interaction with children in high stability stops moving, the structure can realize self-locking through the characteristics of four-bar linkage mechanism, preventing displacement of the four limbs when static.
[0070] The staggered connection of the third link 113 and the fourth link 114: through staggered design, a trapezoidal gap 19 is formed during movement, and the stability of the limbs is ensured through a geometric locking mechanism when stationary. This design allows the bionic mechanical deer to naturally maintain its posture when stopped, without the need for additional locking devices, thus facilitating interaction with children.
[0071] The four-bar linkage not only provides stability in the mechanical structure, but also closely cooperates with the drive system of the bionic mechanical deer to achieve efficient bionic movement. The drive system includes a worm gear mechanism 9 and a crank rocker mechanism 8, which are driven by a multi-phase controlled stepper motor 13 to drive the four-limb structure of the bionic mechanical deer, achieving precise bionic movement. The drive motor 13 rotates through the fixed connection of the worm 12 with the output shaft 131, the worm 12 meshes with the worm gear 14, and the crank rocker mechanism 8 converts the rotary motion into reciprocating swing motion of the four-limb structure. The multi-tooth meshing transmission design of the worm gear mechanism ensures the stability and accuracy of power transmission, providing stable output of the bionic mechanical deer in various motion states. The crank rocker mechanism 8 is connected to the four-bar linkage 11, and through precise control of the drive system, the synchronous movement of the four-limb structure of the bionic mechanical deer is achieved. The four-bar linkage 11 effectively disperses the stress on each link through the stability of the double-triangle trapezoidal structure during movement, ensuring the smoothness and consistency of the movement.
[0072] In natural science education, the bionic mechanical deer as an educational tool can help students more intuitively understand the animal movement mechanism. Thanks to the stability design of the double-triangle trapezoidal structure 17 and the four-bar linkage 11, the bionic mechanical deer can run stably on uneven ground or complex outdoor environments. This feature allows it to provide students with a more realistic bionic simulation experience in outdoor education scenarios such as nature reserves or outdoor activity classes at school. The design of the double-triangle trapezoidal structure 17 significantly improves the torsional resistance of the bionic mechanical deer's limbs, allowing it to maintain high stability during movement. The four-bar linkage 11 ensures the structural stability of the bionic mechanical deer when stationary through the geometric self-locking principle, avoiding the shaking problem of traditional bionic machines when stopped. In addition, the four-bar linkage 11 used in conjunction with the worm gear mechanism 9 and the crank rocker mechanism 8 effectively absorbs the shock during movement through the stability of the double-triangle trapezoidal structure, providing a more stable bionic movement effect.
[0073] In summary, the combination of the double-triangle trapezoidal structure 17 and the four-bar linkage mechanism 11 not only enhances the structural stability of the bionic mechanical deer in theory, but also significantly improves the stability, smoothness and reliability of the bionic mechanical deer in different environments through specific component design and power transmission scheme in practical application.
