Description

Filming rig for stop motion animation

technical field

The utility model relates to a photographing device, in particular to a photographing device used for shooting stop-motion animation.

Background technique

Stop-motion animation is to shoot objects frame by frame and then make them show continuously, so that people can have the visual effect of movement. Stop-motion animation, as it is commonly referred to, is generally performed by characters made of clay puppets, puppets, or mixed materials. The history of this form of animation is as long as the history of hand-drawn animation in the traditional sense, and may even be older.

The production of stop-motion animation is very professional. It mainly uses a digital camera as the shooting equipment, and it uses a single picture to shoot. Therefore, it is required that the camera cannot move continuously, whether it is pushing, pulling, shaking, moving or lifting. The requirement is stepping movement; at the same time, the digital camera is also required to run stably during the stepping movement, and there should be no slight shaking to make the digital camera deviate from the running track. If it deviates, it will be re-shot, so the stability of the camera is also very high . The Chinese patent application date is August 7, 2009, and the application number is 200910041718.4, which discloses a kind of stop-motion animation shooting device, including a moving car, a vertical moving mechanism and a horizontal moving mechanism, and the vertical moving mechanism is arranged on the moving car. On the base, the vertical moving mechanism includes a vertical sliding sleeve and a vertical sliding pipe. The vertical sliding pipe is provided with a vertical sliding groove or a vertical sliding key, and the vertical sliding sleeve is provided with a vertical sliding key or a vertical sliding key. The base is equipped with a 360-degree rotating step controller, and the vertical slide tube is provided with a vertical step control mechanism; the lateral movement mechanism includes a horizontal slide sleeve and a horizontal slide tube, and the horizontal slide tube is provided with a horizontal chute or Horizontal sliding key, the horizontal sliding sleeve is provided with a horizontal sliding key or a horizontal chute, and the horizontal sliding tube is provided with a shooting machine bracket and a horizontal step control machine; the horizontal sliding sleeve is fixed on the vertical sliding sleeve through a fixing plate, and the fixing plate There is a 180-degree rotating step controller on the top; it also includes a track on which a positioning ruler is provided. The invention can make the movement of the camera lens of the stop-motion animation shooting machine smooth and natural, with good stability and high precision. But in this scheme, the digital camera is placed on the cloud platform, and the cloud platform cannot realize multi-angle shooting and rotation, thus affecting the shooting range of the digital camera and reducing the flexibility of operation.

The universal joint is a joint connecting two levers. The joint consists of a pair of hinges with a relative orientation of 90°, so that the levers can be turned in any direction.

Contents of the invention

In order to overcome the deficiencies of the prior art, the utility model provides a shooting device capable of providing a stable platform for multi-angle shooting, compared with manual shooting, which can effectively avoid shaking of the digital camera.

The technical solution adopted by the utility model to solve the technical problems is: a shooting device for stop-motion animation shooting, including a moving vehicle, a moving mechanism and a cloud platform installed on the moving vehicle, and the moving mechanism includes a vertical moving mechanism And the lateral movement mechanism, the cloud platform is installed at the lateral movement mechanism, and also includes a revolving mechanism and a pitching mechanism, and the revolving mechanism includes:

a rotating shaft vertically arranged at the lateral movement mechanism and rotatably matched with the lateral movement mechanism;

A driven gear fixed coaxially with the rotating shaft;

A driving motor, the output shaft of the driving motor is fixed with a driving gear meshed with a driven gear; the pitching mechanism includes:

The connecting frame suspended under the turnover mechanism, the connecting frame and the rotating shaft are connected by universal joints;

A hydraulic cylinder, one of the shaft ends of the hydraulic cylinder is hingedly matched with the end face of the driven gear, and the other shaft end of the hydraulic cylinder is hingedly matched with the connecting frame;

The platform is fixedly connected with the connecting frame.

The beneficial effect of the utility model is: by driving the driving gear at the output shaft of the motor to drive the driven gear to rotate together, then the connecting frame and the pan platform suspended below the driven gear will also rotate together, thereby realizing the installation at the pan platform The digital camera rotates in the circumferential direction, that is, it rotates 360° around the axis of rotation. At the same time, through the expansion and contraction of the hydraulic cylinder, the connecting frame and the pan-tilt can swing around the movable joints of the universal joint, thereby controlling the digital camera to realize the pitching and shooting action in the vertical direction. The utility model can provide a multi-angle control structure basis for the digital camera, and compared with manual shooting, the utility model can effectively avoid the shaking of the digital camera.

The connecting frame includes a vertical rod fixed with the universal joint, and a mounting platform fixed with the vertical rod. The vertical rod and the mounting platform are integrally structured, and the pan-tilt is installed at the mounting platform. The mounting platform with integrated structure has a stronger load-bearing capacity, and provides a stable mounting platform for some large-volume and heavy-weight digital cameras, making it more reassuring to use.

The cylinder body of the hydraulic cylinder is hingedly matched with the end face of the driven gear, and the hydraulic rod of the hydraulic cylinder is hingedly matched with the connecting frame. This scheme can ensure that the hydraulic cylinder is more stable when working.
