Abstract: A suction cup assembly includes a suction cup, a housing assembly, a connection assembly, and a control assembly. When the control assembly controls the suction cup to adhere to an external surface that has water stains or accumulated water, the control assembly evacuates air from an adsorption cavity of the suction cup, thereby drawing water stains or accumulated water into the connection assembly along with the air. The moisture-laden air is then discharged out of the housing assembly. As a result, the internal components of the suction cup assembly are less affected by environmental conditions and is provided with a moisture-resistant function.

Abstract: A transmission structure for a counterweight-free vehicle-mounted jib arm, including a servo cylinder and a stabilizer link component, wherein the servo cylinder is mounted on a main structural framework and connected to the stabilizer link component to push the stabilizer link component. The stabilizer link component is further connected to an arm docking component, and the servo cylinder acts on the arm docking component via the stabilizer link component. Additionally, gas springs are included in the jib arm support structure, arranged on two sides of the servo cylinder and connected to the stabilizer link component. The servo cylinder drives the stabilizer link component to act on the arm docking component, and changes its direction of movement, altering the force from tension to thrust, thereby modifying the force-bearing structure of the servo cylinder, eliminating the damage. This design effectively protects the servo cylinder's structure, enhances equipment safety, and extends its service life.

Abstract: A rotation control method, device, and computer storage medium are disclosed. The method is applicable to a rotation control device designed to drive a first component and a second component to rotate relative to each other. The method encompasses the following steps: identifying the relative rotation angle between the first component and the second component; and determining the angle range for the identified rotation angle. Notably, the first component and the second component are operable to rotate relative to each other within multiple preset angle ranges. As the rotation angle varies within a specific range, the damping between the first component and the second component is controlled to change correspondingly, thereby simulating diverse usage feels for the user.

Abstract: The present disclosure relates to shock-absorption technology, particularly a shock-absorption structure that includes a first shock-absorption body, a second shock-absorption body, and at least one set of elastic shock-absorbing components. The first shock-absorption body surrounds the exterior of the second shock-absorption body, forming a movable gap between the first shock-absorption body and the second shock-absorption body. Both shock-absorption bodies are connected with the elastic shock-absorbing components. The shock-absorption first body is equipped with a first mounting point for affixing an external device, while the second shock-absorption body features a second mounting point for the same purpose. An external camera and an external shock-absorbing arm structure can be installed at the respective mounting points of the first and second shock-absorption bodies.

Abstract: A shock-absorption head includes a connector, a moving component, a supporting component, and a shock-absorption structure. The shock-absorption head can induce a swaying motion in the supporting component, counteracting any tendency of a camera to swing. This motion, facilitated by the shock-absorption structure's telescopic movement, effectively mitigates the centrifugal force resulting from the camera's oscillation. The shock-absorption head can minimize the risk of detachment between the camera and the shock-absorption arm, thereby preventing camera instability and ensuring the steadiness of the captured image.

Abstract: A shock absorption mechanism includes connectors, supporting components, and shock absorption components capable of driving the supporting components to swing back and forth or left and right. The connectors are clamped in the middle of the shock absorption components and are operatively connected to the shock absorption components on both sides. The supporting components are movably connected to the shock absorption components, and the lower end of the connectors is operatively connected 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 damping arm and averting camera jitter.

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.
