AI summary

The present disclosure introduces a shock absorption mechanism, regulating method, and control method, particularly applicable to shock absorption technology for devices like in-vehicle filming equipment. The system comprises connectors, shock absorption components, and supporting components. The connectors exhibit movable connections with the shock absorption components, while the supporting components establish drivable connections with the shock absorption components. Additionally, the connectors are also movably linked to the supporting components. A notable feature of this invention, distinct from existing technologies, is the shock absorption components' capacity to induce front-back or left-right oscillations in the supporting components through their inherent rotation when detecting a tendency for swinging. This proactive response effectively mitigates the centrifugal force resulting from camera swinging, preventing detachment between the camera and the shock absorption arm and averting camera jitter. Consequently, the stability of the recorded footage is assured.
