Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary shooting, in particular to a panoramic video stabilizer. Background Technique

[0002] With the continuous development of shooting equipment and short videos, more and more people begin to learn shooting techniques by themselves. Naturally, while learning shooting, the requirements for shooting equipment are also getting higher and higher. Especially for outdoor shooting, due to the influence of various outdoor factors, especially some panoramic video shooting devices, they have higher requirements for stability and adjustability.

[0003] The existing panoramic shooting stabilization methods are generally divided into two types. One is that some shooting equipment has a built-in anti-shake function, and the shooting camera can overcome the received shaking force by itself to ensure the stability of shooting. There is also a part that uses an external buffer device. Most of these buffer devices use the elastic force of springs to support the stability of the shooting equipment.

[0004] These shooting video stabilization methods have some problems. For example, cameras with built-in anti-shake functions are expensive, and spring-type buffers cannot horizontally and vertically limit external forces during use, resulting in unstable shooting images. For this reason, we propose a panoramic video stabilizer. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is to overcome the existing defects and provide a panoramic video stabilizer. Through a simple mechanism, while having a low cost, it can effectively prevent the panoramic video device from being affected by horizontal and vertical forces and causing shaking of the shooting image, and can effectively solve the problems in the background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: a panoramic video stabilizer, including an extension rod and a stabilization mechanism;

[0007] Extension rod: Its rear end is fixedly connected with a mounting bracket;

[0008] Stabilization mechanism: It includes a rotating shaft, a first semi-circular ring, an arc-shaped groove, a first sliding column, a limiting column, a second semi-circular ring and a shooting device placement plate. The rotating shafts are respectively rotatably connected to the left and right sides of the upper end of the mounting bracket. A first semi-circular ring is fixedly connected between the two rotating shafts. An arc-shaped groove is opened in the middle of the first semi-circular ring. The first sliding columns are symmetrically slidably connected to the left and right inside the arc-shaped groove. The upper ends of the first sliding columns are fixedly connected to a second semi-circular ring. Limiting columns are fixedly connected to the ends of the two first sliding columns. A shooting device placement plate is fixedly connected inside the second semi-circular ring. Through a simple mechanism, while having a low cost, it can effectively prevent the panoramic video device from being affected by horizontal and vertical forces and causing shaking of the shooting image.

[0009] Further, it further includes a storage battery, which is arranged in the middle of the outer arc surface of the extension rod, and an external power supply is connected to the charging port of the storage battery.

[0010] Further, it further includes a single-chip microcomputer, which is arranged in the middle of the outer arc surface of the extension rod, and the input end of the single-chip microcomputer is electrically connected to the output end of the storage battery.

[0011] Further, it further includes a second sliding column, which is fixedly connected to the middle of the lower surface of the shooting device placement plate. The outer arc surface of the second sliding column is slidably connected to the inside of the arc-shaped groove, and a counterweight is provided at the lower end of the second sliding column.

[0012] Further, it further includes a rubber anti-slip sleeve, which is evenly arranged on the outer arc surface of the extension rod.

[0013] Further, it further includes an inclination sensor, which is arranged in the middle of the lower surface of the counterweight, and the inclination sensor is bidirectionally electrically connected to the single-chip microcomputer.

[0014] Further, it further includes a threaded hole, which is arranged on the front surface of the extension rod.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows: The panoramic video stabilizer has the following advantages:

[0016] 1. When the video stabilizer needs to be used, install the panoramic video device on the shooting device placement plate. During this period, the entire stabilizer can be manually picked up through the rubber anti-slip sleeve, or the stabilizer can be installed on the designated station through the threaded hole. There are two ways to use the device, namely manual and installation, to meet different shooting requirements.

[0017] 2. When the panoramic video device is subjected to an inclination force, due to the influence of the earth's gravity, the counterweight pulls the second semi-circular ring downward through the second sliding column. Under the influence of this force, the two first sliding columns change their left and right inclination angles in the arc-shaped groove, thereby offsetting the lateral inclination angle change of the second semi-circular ring. The rotating shaft cooperates with the first semi-circular ring to offset the longitudinal inclination angle change of the second semi-circular ring. Through the self-adaptation of the inclination angle and the real-time measurement of the inclination sensor, the stability of the shooting device placement plate is ensured. Through a simple mechanism, while the cost is low, it can also effectively prevent the problem that the shooting image shakes due to the lateral and longitudinal forces on the panoramic video device.

The input end of the single-chip microcomputer 8 is electrically connected to the output end of the storage battery 9. It also includes a rubber anti-slip sleeve 7, which is evenly arranged on the outer arc surface of the extension rod 1. When the video stabilizer needs to be used;

[0024] Stabilizing mechanism 3: It includes a rotating shaft 31, a first semi-circular ring 32, an arc-shaped groove 33, a first sliding column 34, a limiting column 35, a second semi-circular ring 36, and a shooting device placement plate 37. The rotating shaft 31 is respectively rotatably connected to the left and right upper ends of the mounting bracket 2. A first semi-circular ring 32 is fixedly connected between the two rotating shafts 31. An arc-shaped groove 33 is provided in the middle of the first semi-circular ring 32. The first sliding columns 34 are symmetrically and slidably connected to the left and right inside the arc-shaped groove 33. The upper ends of the first sliding columns 34 are fixedly connected to a second semi-circular ring 36. Limiting columns 35 are fixedly connected to the ends of the two first sliding columns 34. A shooting device placement plate 37 is fixedly connected inside the second semi-circular ring 36. It further includes a second sliding column 4. The second sliding column 4 is fixedly connected to the middle of the lower surface of the shooting device placement plate 37. The outer arc surface of the second sliding column 4 is slidably connected to the inside of the arc-shaped groove 33. A counterweight 5 is provided at the lower end of the second sliding column 4. It further includes an inclination sensor 6. The inclination sensor 6 is arranged in the middle of the lower surface of the counterweight 5. The inclination sensor 6 is bidirectionally electrically connected to the single-chip microcomputer 8. It further includes a threaded hole 10. The threaded hole 10 is arranged on the front surface of the extension rod 1. Install the panoramic video device onto the shooting device placement plate 37. At this time, adjust the single-chip microcomputer 8, and the inclination sensor 6 operates. The inclination sensor 6 measures the horizontal information of the counterweight 5 in real time. During this period, the entire stabilizer can be manually picked up through the rubber anti-slip sleeve 7, or the stabilizer can be installed onto the designated station through the threaded hole 10. When the panoramic video device is subjected to an inclination force, the counterweight 5 is affected by the gravitational force of the earth, and then pulls the second semi-circular ring 36 downward through the second sliding column 4. Under the influence of this force, the two first sliding columns 34 change their left and right inclination angles in the arc-shaped groove 33, thereby offsetting the lateral inclination angle change of the second semi-circular ring 36.

Through the self-adaptation of the inclination angle and the real-time measurement of the inclination sensor 6, the stability of the shooting device placement plate 37 is ensured, and thus the stability of the panoramic video device is ensured.

[0025] The working principle of the panoramic video stabilizer provided by the present utility model is as follows: When the video stabilizer is to be used, the panoramic video device is installed on the shooting device placement plate 37. At this time, the single-chip microcomputer 8 is adjusted, and the inclination sensor 6 operates. The inclination sensor 6 measures the horizontal information of the counterweight 5 in real time. During this period, the entire stabilizer can be manually picked up through the rubber anti-slip sleeve 7, or the stabilizer can be installed on the designated work station through the threaded hole 10. When the panoramic video device is subjected to an inclination force, the counterweight 5 is affected by the gravitational force of the earth, and the second semi-circular ring 36 is pulled downward by the second sliding column 4. Under the influence of this force, the two first sliding columns 34 change their left and right inclination angles in the arc-shaped groove 33, thereby offsetting the lateral inclination angle change of the second semi-circular ring 36. The rotating shaft 31 cooperates with the first semi-circular ring 32 to offset the longitudinal inclination angle change of the second semi-circular ring 36. Through the self-adaptation of the inclination angle and the real-time measurement of the inclination sensor 6, the stability of the shooting device placement plate 37 is ensured, and thus the stability of the panoramic video device is ensured.
