Description

Technical Field

[0001] The present invention belongs to the technical field of portable video recording equipment, and in particular relates to a self-media mobile recording device. Background Art

[0002] Self-media refers to a media form in which individuals or small organizations use digital technology and the Internet platform to independently produce, publish and disseminate content. Its core feature is that it breaks the monopoly of traditional media on information dissemination, allowing every ordinary user to become a content creator and disseminator. The main carriers include WeChat public accounts, Weibo, and other social media platforms. The content forms include pictures, short videos, live broadcasts, audio, comics and other forms. Compared with traditional media, self-media has the advantages of high creative freedom, fast dissemination speed, and strong user interactivity. The emergence of self-media has not only changed the traditional way of information dissemination, but also spawned many new business models. At the same time, it has also occupied an increasingly important position in the fields of public opinion guidance, cultural communication, and commercial marketing.

[0003] When existing self-media conduct outdoor live broadcasts or outdoor video shooting, they generally need to use mobile recording equipment to expand the shooting range of the recorder and obtain a wider recording angle. Some existing mobile recording equipment has the function of rotating left and right as the recorder moves horizontally, so as to bring the recorder back into the recording screen. However, this mobile recording equipment can usually only rotate left and right. When the user holds the mobile recording equipment, the recorder moves out of the screen due to the up and down swinging of the recorder while the user is holding the mobile recording equipment. Since this mobile recording equipment does not have the function of adjusting the pitch angle of the recorder, the mobile recording equipment cannot adjust the camera angle of the recorder to ensure that the recorder is always in the center of the screen.

The outer surface of the gear 11 is meshed with the outer surface of the toothed plate 23.

[0021] When the videographer starts the No. 1 motor 9, the circular shaft 10 and the gear 11 begin to rotate. Since the outer surface of the gear 11 and the outer surface of the gear plate 23 are engaged with each other, the gear plate 23 as a whole begins to move under the drive of the gear 11.

[0022] Among them, the upper surface of the circular plate 4 is fixedly connected to the mounting block 13, the upper surface of the mounting block 13 is fixedly connected to the placement plate 14, and movable grooves 15 are provided on the front and rear sides of the upper surface of the placement plate 14. The inner surface of the movable groove 15 is movably connected to a movable plate 16. There are two movable plates 16. A video recorder 18 is movably installed on the inner surface between the two movable plates 16. The lower surface of the video recorder 18 is movably connected to the upper surface of the placement plate 14.

[0023] The design of the movable groove 15 serves to limit the moving direction and range of the movable plate 16. At the same time, the shape, material and rough design of the movable plate 16 ensure that when the two movable plates 16 clamp the video recorder 18, it will not cause damage to the outer surface of the video recorder 18, and it also ensures that the video recorder 18 will be fixed by the two movable plates 16.

[0025] When the videographer starts the second motor 19, the rotating shaft 20 and the long rod 21 begin to rotate.

[0026] The front and rear ends of the long rod 21 are hinged with short rods 22 . There are two short rods 22 . The other ends of the two short rods 22 are hinged to the lower surfaces of the two movable plates 16 , respectively.

[0027] When the long rod 21 starts to rotate, the two ends of the long rod 21 will respectively drive the two short rods 22, thereby causing the two short rods 22 to start rotating. At the same time, the other end of the short rod 22 will drive the movable plate 16, thereby causing the two movable plates 16 as a whole to start moving toward and away from each other along the inner surface of the movable groove 15.

[0028] Among them, an L-shaped ring 24 is movably connected to the lower side of the inner surface of the hollow block 1, and the bottom end of the L-shaped ring 24 is fixedly connected to the intelligent control module 25. The upper surface of the intelligent control module 25 is movably connected to the lower surface of the hollow block 1. A rotating motor 26 located on the right side of the telescopic plate 7 is fixedly installed in the middle of the upper surface of the intelligent control module 25. The other end of the output shaft of the rotating motor 26 is fixedly connected to a rotating shaft 27. The top end of the outer surface of the rotating shaft 27 passes through the fixed plate 8 and extends to the upper surface of the fixed plate 8 and is fixedly connected to the inner surface of the fixed plate 8.

[0029] When the rotating motor 26 starts running, the rotating shaft 27 will start to rotate, thereby causing the fixed plate 8 as a whole, the hollow block 1, the telescopic plate 7 and the circular plate 4 to start rotating as a whole. The design of the intelligent control module 25 and the L-shaped ring 24 plays a role in keeping the hollow block 1 as a whole stable during the rotation process, and the intelligent control module 25 plays a role in controlling the rotating motor 26 and the No. 1 motor 9. The video recorder 18 can transmit information with the intelligent control module 25 through wireless transmission methods such as Bluetooth.

[0030] Among them, the left side of the outer surface of the intelligent control module 25 is fixedly connected to a telescopic rod 28, and the outer surfaces of the front and rear sides of the telescopic rod 28 are provided with sliding grooves 31. The outer surface of the telescopic rod 28 and the inner surface of the sliding groove 31 are movably connected to a hollow box 30, and the left end of the hollow box 30 is fixedly connected to a handle 39.

[0031] The design of the telescopic rod 28 , the hollow box 30 and the sliding slot 31 serves to limit the overall moving direction and range of the telescopic rod 28 .

[0032] Among them, a fixing rod 32 is fixedly sleeved on the right side of the top surface of the inner cavity of the hollow box 30, the top end of the fixing rod 32 passes through the hollow box 30 and extends to the upper surface of the hollow box 30, the outer surface of the fixing rod 32 is fixedly sleeved on the inner surface of the hollow box 30, and a driven wheel 33 is movably installed on the outer surface of the fixing rod 32. A No. 3 motor 34 located on the left side of the telescopic rod 28 is fixedly installed on the left side of the bottom of the inner cavity of the hollow box 30, and the other end of the output shaft of the No. 3 motor 34 is fixedly sleeved on the driving shaft 35. The top end of the driving shaft 35 passes through the hollow box 30 and extends to the upper surface of the hollow box 30, the outer surface of the driving shaft 35 is movably sleeved on the inner surface of the hollow box 30, and the outer surface of the driving shaft 35 is fixedly sleeved with a driving wheel 36.

[0033] The design of the fixing rod 32 allows the driven wheel 33 to rotate only around the fixing rod 32 , and when the third motor 34 is started, the driving shaft 35 and the driving wheel 36 will start to rotate.

[0034] Among them, the driving wheel 36 and the driven wheel 33 are connected by a transmission belt 37, and the movable block 29 is fixedly connected to the left side of the front surface of the transmission belt 37. The lower surface of the movable block 29 is fixedly connected to the upper surface of the telescopic rod 28, and the upper surface of the movable block 29 is movably connected to the inner surface of the hollow box 30.

[0035] When the driving wheel 36 starts to rotate, the transmission belt 37 and the driven wheel 33 will start to rotate. At this time, the movable block 29 will start to move to the right with the rotation of the transmission belt 37, thereby causing the telescopic rod 28, the movable block 29 and the intelligent control module 25 to start to move to the right as a whole.

[0036] Among them, the left and right sides of the top of the inner cavity of the hollow box 30 are fixedly connected with limit plates 38 located in front of the transmission belt 37. There are two limit plates 38, which are respectively located on the left and right sides of the movable block 29.

[0037] The design of the limit plate 38 serves to limit the overall moving range of the movable block 29 and the telescopic rod 28 .

[0038] The working principle and use process of the present invention: First, the video recorder places the video recorder 18 on the placement plate 14 and starts the No. 2 motor 19. As the No. 2 motor 19 runs, the rotating shaft 20 and the long rod 21 will start to rotate, thereby causing the two short rods 22 to also start to rotate. At the same time, the other ends of the two short rods 22 will respectively drive the two moving plates 16, thereby causing the two moving plates 16 to start running towards each other as a whole. Finally, the two rubber layers 17 will clamp the video recorder 18, thereby fixing the video recorder 18 on the placement plate 14.

[0039] When the videographer needs to expand the field of view of the video screen, the videographer starts the No. 3 motor 34. As the No. 3 motor 34 runs, the driving shaft 35, the driving wheel 36 and the transmission belt 37 begin to rotate, and the rotation of the transmission belt 37 drives the movable block 29, thereby causing the telescopic rod 28 to gradually move to the right side of the hollow box 30. At this time, the total length of the hollow box 30 and the movable block 29 will gradually increase, thereby expanding the video field of the video recorder 18.

[0040] When the person being recorded walks on a rough and uneven road surface, causing the person being recorded to disappear from the field of view of the video recorder 18, the rotating motor 26 and the No. 1 motor 9 will be started under the control of the intelligent control module 25. The operation of the rotating motor 26 will cause the hollow block 1 as a whole, the circular plate 4 as a whole and the video recorder 18 to start rotating left and right, and the operation of the No. 1 motor 9 will cause the circular shaft 10 and the gear 11 to start rotating. At this time, the toothed plate 23, the telescopic plate 7 and the driving rod 6 will start to move upward under the engagement of the gear 11. The movement of the driving rod 6 will drive the connecting plate 5, thereby causing the connecting plate 5 and the circular plate 4 as a whole to start rotating up and down with the top of the connecting ball 2 as the axis, thereby realizing the adjustment function of the pitch angle of the video recorder 18. Finally, under the joint action of the No. 1 motor 9 and the rotating motor 26, the video recorder 18 will be realigned with the person being recorded, thereby ensuring that the person being recorded is always in the video screen.
