Abstract: The present disclosure pertains to the technical realm of photographic equipment, introducing a self-adjusting shock-absorption device that incorporates a movable frame and a shock-absorption mechanism. The movable frame is designed to rotate along at least one pivot. The shock-absorption mechanism comprises an adjusting component and an elastic component, where the elastic component is flexibly positioned within the movable frame, with at least one of its ends linked to the adjusting component. The end of the adjusting component, distant from the elastic component, is also movably attached to the movable frame. As the movable frame rotates along its pivot, the adjusting component dynamically shifts, resulting in a modulation of the elastic component's length.

Abstract: 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.

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.

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 microphone adjustment apparatus includes a support rod on which a mounting position is provided for the installation of a microphone and an adjusting rod. The microphone adjustment apparatus also includes a transmission mechanism through which the adjusting rod is connected to the support rod. The adjusting rod, after rotating around a first axis, drives the support rod to rotate around a second axis through the operation of transmission mechanism. The coordination between the support rod, adjusting rod, and the transmission mechanism can, without the direct rotation of support rod, drive the support rod to rotate by rotating the adjusting rod. Compared to directly rotating the support rod, the present disclose provides a more convenient microphone adjustment apparatus that can effectively reduce harm to the wrist of an operator.

Abstract: A suction cup air control system includes a suction cup body and an air control system for regulating the suction capability of the suction cup body. The air control system is connected to the suction cup body and consists of a high-pressure vacuum cylinder for controlling the suction of the suction cup body and a control pump for extracting and expelling air from the high-pressure vacuum cylinder. The high-pressure vacuum cylinder is linked to the suction cup body, while the control pump is connected to the high-pressure vacuum cylinder. The present disclosure utilizes the high-pressure vacuum cylinder and control pump to extract air from the suction cup body, resulting in faster vacuum suction, thereby ensuring immediate adsorption and stable installation of the suction cup.

Abstract: The present disclosure belongs to the field of microphone equipment, in particular to a backpack microphone stand. The backpack microphone stand includes a support rod, an adjustment system, a backpack mechanism, and a support component for the support rod. The support rod is provided with a mounting position of a microphone, one end of the support component is movably connected with the support rod and the other end is movably connected with the backpack mechanism. The adjustment system is movably connected with the support rod to adjust the pitch angle of the support rod. With the disclosed backpack microphone stand, the effort or force needed to operate the equipment is greatly reduced. Therefore the operator's hands and arms will suffer less fatigue, and injury to the wrists can be effectively reduced.

Abstract: A modular suction cup device comprises a suction cup body and an air control system module for regulating the adhesion of the suction cup body. The suction cup body includes an absorption chamber for adhering to an external structure or surface on one side of the absorption chamber, while the air control system module is detachably installed on the suction cup body and connected to the absorption chamber. In the present disclosure, the modular design of the air control system module and its detachable connection to the suction cup body enhance the convenience of installation and removal, particularly during maintenance or replacement operations.

Abstract: A microphone stand comprises a support rod and a support component for supporting the support rod, wherein the support rod is provided with a mounting position for mounting a microphone, and the support component is movably connected to the support rod. The support rod is provided with an adjustment system at an end of the support rod away from the support component to adjust the pitch angle of the support component. The adjustment system and the support component greatly reduce the workload of the operator and potential injury of the operator.

The rotating part comprises a housing (1) provided above the base (10), a frame (37), counterweight blocks (36), a servo electric cylinder (35), a motor (38), a pinion (40), and a large gear (41). The servo electric cylinder (35) is connected to a rapid abutting structure (2) by means of a clamping member (43). The rapid abutting structure (2) is connected to the jib. The other end of the jib is connected to a gimbal camera mounting plate (6) by means of the damping part. The damping part comprises damping springs (8) and a universal joint structure consisting of a pitch damping rod and left and right swing damping rods. A air spring (34) is provided between the frame (37) and the clamping member (43). One end of the air spring (34) is connected onto the clamping member (43), and the other end of the air spring (34) is connected onto the frame (37).

Abstract: In servomechanisms, like for example used in disk drives, disturbances, for example, friction, shock and vibration, prevent the system positioning accuracy from further improvement. These disturbances occur in a relatively low-frequency range compared to the electrical dynamics. In the present invention, an acceleration feedback control loop using a frequency-separated acceleration soft sensor (350) replaces the conventionally used current control loop in the low frequency range, where the disturbances occur, so as to attenuate the influence of the disturbances enclosed in the loop. The current feedback continues to manage the electrical dynamics in the high-frequency range. Estimating the required acceleration signal by a soft sensor (350) eliminates the need for physical accelerometers, which reduce system reliability and increase system cost.
