AI Technical Summary
Traditional shock absorber arm structures are difficult to effectively buffer the camera's instability caused by shaking and lateral inertia during shooting, which can lead to the camera becoming detached from the main body of the shock absorber arm.
By incorporating connectors, support components, and shock-absorbing assemblies into the shock-absorbing mechanism, the rotation of the shock-absorbing assemblies drives the support components to swing back and forth or left and right. This detects the camera's tendency to sway and allows for autonomous rotation in advance, buffering the camera's centrifugal force and preventing it from falling off or shaking.
This ensures camera stability during filming, preventing it from detaching from the shock-absorbing arm and guaranteeing the stability of the captured footage.

Description
TECHNICAL FIELD
[0001] The present application belongs to the technical field of shock absorption of vehicle-mounted shooting equipment, and particularly relates to a shock absorption mechanism, a shock absorption control method and a shock absorption control method thereof. BACKGROUND
[0002] When a vehicle-mounted shooting device moves a lens for shooting indoors or outdoors, for example, when shooting a vehicle driving, in order to keep the camera up with the shooting picture, some auxiliary tools such as a vehicle are usually used to connect the camera to a vehicle shooting support, and the vehicle shooting support is fixed to the vehicle, so as to keep up with the shooting picture. However, during the shooting process, the road conditions for shooting will affect the camera and the vehicle shooting support, and the lens will shake during movement. In order to avoid large shaking and stabilize the shooting picture, a shock absorbing arm or the like is usually used to install the camera. The conventional shock absorbing arm usually uses a shock absorbing spring to be installed on the shock absorbing arm body, and a camera connecting assembly for connecting the camera is connected to the head of the shock absorbing arm body. The overall structure is buffered by the shock absorbing spring.
[0003] As disclosed in the existing patent with application number CN202110273411.8, a shock absorbing head, a vehicle-mounted shock absorbing arm and a vehicle-mounted shooting device, the shock absorbing head includes an external structure, a buffer assembly and a connecting assembly. The buffer assembly includes at least one first sliding rod and a second sliding rod arranged in parallel and spaced apart. The first sliding rod and the second sliding rod are arranged vertically, and each is sleeved with two elastic members. The external structure is slidably sleeved on the second sliding rod and clamped between the two elastic members of the second sliding rod. The second sliding rod is slidably sleeved on the first sliding rod and clamped between the two elastic members of the first sliding rod. The connecting assembly is fixedly connected with the buffer assembly and is used for connecting a photographic accessory. In the patent, the elastic members are springs. When the gimbal moves forward and backward along a direction parallel to the first sliding rod or the second sliding rod, the springs are compressed or stretched, thereby slowing down the left-right or forward-backward movement of the camera installed on the gimbal, and shock absorption is achieved.
[0004] As known from the above, the shock absorbing arm structure disclosed in the above patent buffers the overall structure by a shock absorbing spring. However, during the shooting process, due to the inevitable shaking and lateral inertia of the camera, the camera and the head of the shock absorbing arm body are easily out of control, and it is difficult to balance the stability loss caused by the shaking or lateral inertia of the camera. SUMMARY
[0005] To solve the above problems, the primary purpose of the present application is to provide a shock absorption mechanism, a shock absorption control method and a shock absorption control method, which can drive the support to swing forward and backward or left and right by its own rotation when the support tends to swing, thereby buffering the centrifugal force of the camera swinging, avoiding the camera from falling off between the shock absorbing arm, and also avoiding the camera from shaking, and ensuring the stability of the shooting picture.

[0011] In this application, the support member is used to mount equipment requiring vibration damping, such as cameras, and the connector is used to connect mounting structures such as pan-tilt heads. The vibration damping component can drive the support member to swing back and forth or left and right, providing rotational buffering and vibration damping functions. During filming, when the camera experiences horizontal shaking and inertial movement, causing it to tend to swing, the support member will also swing under the influence of the camera. At this time, the vibration damping component detects the tendency of the support member to swing and, based on the detection result, rotates autonomously in advance, causing the support member and camera to swing back and forth or left and right in the corresponding direction, moving relative to the connector to buffer the centrifugal force of the camera's swing, preventing the camera from detaching from the vibration damping arm, and also preventing camera shaking, thus ensuring the stability of the filmed footage.

When the shock-absorbing components rotate backward, they provide tension; when they rotate forward, they provide thrust. When the rotation speed and direction of the shock-absorbing components on both sides are the same, they can cause the support member to swing back and forth, buffering the centrifugal force caused by the camera's back-and-forth movement. When the rotation speeds of the shock-absorbing components on both sides are the same but their directions of rotation are different, they can work together to cause the support member to flip, buffering the centrifugal force caused by the camera's shaking. Thus, through the coordination of different tension or thrust forces, the support member can swing horizontally left and right, buffering the camera's swing at any angle, thereby ensuring the stability of the camera's captured footage.

[0066] The present embodiment also provides a damping control method applied to the damping mechanism, which will be described below with reference to Figure 6 , comprising:
[0067] receiving a parameter to be modified; specifically, the parameter can be a voltage.
[0068] controlling the damping of the damping component according to the voltage.
[0069] It can be understood that the damping assembly mainly adopts a brushless motor for damping. According to the brushless motor, the fixed part and the rotating part are mainly rotated through the magnetic force between the coil of the fixed part and the magnet of the rotating part. When the voltage is adjusted, the magnetic force between the coil and the magnet can be changed. For example, when the voltage is increased, the magnetic force between the coil and the magnet is increased. In other words, in the present application, the damping between the fixed part and the rotating part can be adjusted by adjusting the voltage. Thus, the load of the motor of each weight can be adapted.
[0070] The present embodiment also provides a damping control method applied to the damping mechanism. Please refer to Figure 7 , which comprises the following steps:
[0071] The single-chip microcomputer receives the angular velocity of the shaking of the supporting part. It can be understood that the supporting part is connected with the damping assembly. When the supporting part shakes with the camera as the load, the damping mechanism as a whole has a tendency to shake. At this time, the single-chip microcomputer receives the angular velocity of the shaking through the magnetic encoder. Further, the angular velocity can be calculated, and the corresponding stroke of the damping assembly can be controlled according to the calculation result.
[0072] The single-chip microcomputer controls the rotation of the damping assembly according to the angular velocity to buffer the shaking of the supporting part.
[0073] Specifically, the single-chip microcomputer calculates the corresponding torsion under the angular velocity, and controls the damping assembly 3 to generate a corresponding rotating torsion according to the electric value.
[0074] Further, the PID algorithm is used to calculate the voltage value. The single-chip microcomputer polls the first magnetic encoder 3113 and the second magnetic encoder 3114 to obtain the angular velocity of the shaking of the supporting part 2, and calculates the desired control voltage through the PID. According to the desired control voltage, the damping assembly 3 generates a corresponding torsion value, so as to balance and buffer the shaking of the supporting part 2, and finally ensure the shooting stability of the camera. It can be understood that in the present embodiment, the single-chip microcomputer can query the data of the first magnetic encoder 3113 and the second magnetic encoder 3114 once every preset time, for example, once every 10 seconds.
[0075] Further, in the present application, the rotating assembly generates rotation through the principle of the brushless motor. The voltage is taken as a parameter. By increasing or decreasing the voltage, the magnetic force between the coil and the magnet is increased or decreased, the damping adjustment of the damping mechanism is realized, and the shaking of the camera is buffered in real time. Specifically, during operation, the encoder is installed on the rotating part. When the camera shakes and drives the supporting part to deviate, the supporting part drives the rotating part to have a deviation tendency. At this time, the encoder detects the angular velocity of the shaking and sends it to the single-chip microcomputer. The single-chip microcomputer calculates the voltage of the motor generating the corresponding torsion through the PID algorithm, and controls the coil to generate the corresponding torsion according to the voltage, so as to buffer the shaking of the camera in real time.
[0076] The above merely provides the preferred embodiments of the application, and is not used to limit the present application. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present application shall fall in the protected scope of the present application.
