Description

Technical Field

[0001] The invention relates to the field of short video shooting device technology, specifically a self-media short video shooting device and its usage method. Background Technology

[0002] Self-media short video shooting equipment can be mainly divided into several categories: core shooting equipment, audio recording equipment, and auxiliary stabilization and lighting equipment. Among them, core shooting equipment includes the mobile phone itself and the camera. The image quality and image stabilization of current flagship mobile phones are sufficient to meet the needs of daily short video and vlog shooting. With the help of editing software, the entire process from shooting to output can be completed directly. Audio recording equipment includes lavalier wireless microphones. Auxiliary stabilization equipment includes mobile phone stands, which are suitable for fixed-position shooting (voiceover, time-lapse photography) to avoid image shaking. Lighting includes LED lights, flash, and softboxes, which can effectively improve the image quality.

[0003] Taking a phone stand as an example, most existing phone stands can only fix the phone in a certain position on the table. The person shooting the short video will move around in front of the table, and sometimes they will move to the other side of the table to introduce the content. Their face will move out of the phone screen, and then the person shooting will not be captured. It is necessary to manually adjust the angle of the phone, which is quite inconvenient during the video shooting process. Summary of the Invention

[0004] To address the problems mentioned in the background art, the purpose of this invention is to provide a self-media short video shooting device and its usage method. This device allows the phone holder to automatically adjust the phone's rotation angle, following the user's face without requiring frequent manual adjustments, thus improving ease of operation and ensuring video quality. It solves the problem that most existing phone holders can only fix the phone in one position on a table, and the user may move around, sometimes to the other side of the table to introduce the content, causing their face to move off the phone screen, making them unviewable and requiring manual adjustment of the phone's angle – a significant inconvenience during video shooting.

[0005] To achieve the above objectives, the invention provides the following technical solution: a self-media short video shooting device and its usage method, comprising a column, a base, and a frame, characterized in that: the top of the base is fixedly connected to the column, the frame is fixedly installed on the rear side of the column, a placement groove is provided on the top of the column, a clamping mechanism is provided above the placement groove, a mobile phone body is fixedly clamped on the clamping mechanism, a turning mechanism for turning the mobile phone body is provided below the clamping mechanism, an adjustment mechanism for moving the mobile phone body back and forth is provided on the inner side of the frame, and a support mechanism for assisting in supporting the mobile phone body when it moves back and forth is provided below the adjustment mechanism.

The partition is fixedly installed on the inner wall of the mounting housing. The surface of the rotating rod is rotatably connected to the inner wall of the mounting housing via a bearing. The mounting housing is located inside the placement slot. Sliding grooves are opened on both the left and right sides of the column and the frame. Sliding blocks are fixedly connected to the left and right sides of the mounting housing. The sliding grooves and sliding blocks are slidably engaged. The second controller is fixedly installed on the front side of the column and is signal-connected to the adjustment motor.

[0008] As a preferred embodiment of the invention, the auxiliary support mechanism includes a linkage gear, a second screw, a support plate, an extension plate, and auxiliary wheels. Two linkage gears are arranged vertically and mesh with each other. The top linkage gear is fixedly connected to the front end of the first screw. The second screw is located below the first screw, and its front end is fixedly connected to the bottom linkage gear. The rear end of the second screw extends through to the inner side of the frame and is rotatably connected to the inner wall of the frame via a bearing. The surface of the second screw is rotatably connected to the inner wall of the column via a bearing. The top end of the support plate is drivenly connected to the surface of the second screw, and its bottom end is fixedly connected to the extension plate. Auxiliary wheels are rotatably connected to both ends of the extension plate via rotating shafts, and the outer periphery of the auxiliary wheels makes rolling contact with the tabletop.

[0009] As a preferred embodiment of the invention, the clamping mechanism includes a vertical plate with a movable cavity on its inner side. Two opposing movable plates are slidably connected to the inner wall of the movable cavity via a slider and a groove. An inclined surface is provided on one side of each of the two movable plates, and one side of each movable plate extends to the outer side of the movable cavity. A side plate is fixedly installed on the front side of each movable plate, and a rubber pad is fixedly installed on one side of each side plate. One side of the rubber pad abuts against the mobile phone body. Tension springs are fixedly installed on the opposing sides of both movable plates. A pressure block is provided at the top of the vertical plate, and a pressure rod is fixedly installed at the bottom of the pressure block. The bottom end of the pressure rod extends through the inner side of the movable cavity and is fixedly connected to a push rod. The surface of the pressure rod is slidably connected to the inner wall of the vertical plate. Both ends of the push rod are in slidable contact with the inclined surface on the movable plate. The vertical plate is fixedly installed on the top of the connecting plate.

[0010] As a preferred embodiment of the invention, curved plates are fixedly installed on both the left and right sides of the column, and a contact element is provided above the curved plate. The bottom end of the contact element extends through to the bottom of the curved plate and is fixedly connected to a suction cup. The curved plate is made of iron, and the contact element is made of magnet. The inner wall of the curved plate and the surface of the contact element are attracted to each other.

[0011] As a preferred embodiment of the invention, a dustproof cloth is fixedly installed on the upper rear side of the mounting housing, and the other end of the dustproof cloth is fixedly connected to the top of the frame.

[0012] As a preferred embodiment of the invention, a protective cover is provided on the outer side of the two linkage gears, and the rear side of the protective cover is fixedly connected to the column.

[0013] As a preferred embodiment of the present invention, the first step is as follows: When in use, press down on the pressure block to move the pressure rod and push rod downward. The two ends of the push rod press against the inclined surface of the movable plate. Using the inclined surface transmission principle, the two movable plates are pushed to slide to both sides and stretch the tension spring, so that the two side plates open. After placing the mobile phone body between the two side plates, pull up on the pressure block. The tension spring retracts and drives the movable plate to reset, so that the side plates clamp the mobile phone body through the rubber pad. Step 2: The face tracking camera continuously identifies and locates the subject's face position and transmits the displacement offset electrical signal to the first controller in real time. The first controller has a built-in preset program to calculate and analyze the offset signal and output drive commands to control the start, stop, forward and reverse rotation of the self-locking motor. The self-locking motor drives the first bevel gear at the output end to rotate, which in turn drives the second bevel gear to drive the rotating rod to rotate synchronously. The connecting plate at the top of the rotating rod carries the upper clamping mechanism and the mobile phone body, thereby driving the mobile phone body to rotate horizontally as a whole, realizing the following adjustment of the shooting angle. The self-locking motor can automatically lock after the adjustment is in place to fix the shooting angle. Step 3: When it is necessary to enrich the content of the captured image, the second controller controls the forward and reverse rotation of the adjustment motor. The adjustment motor drives the first screw to rotate, which in turn drives the mounting housing to move back and forth in a straight line along the surface of the first screw with the cooperation of the slider and the slide groove, thus zooming out the viewfinder and allowing more content to appear in the image. Step 4: When the first screw rotates, the top linkage gear rotates synchronously with the first screw, which in turn drives the bottom linkage gear and the second screw to rotate synchronously. The rotation of the second screw will drive the support plate to move back and forth. The support plate drives the bottom extension plate and the auxiliary wheels at both ends to move synchronously. The auxiliary wheels always roll in contact with the table. During the back and forth adjustment of the mobile phone body, the support plate moves synchronously with the mobile phone body, providing support for the column, mounting shell and frame and other structures.

[0014] Compared with existing technologies, the beneficial effects of the invention are as follows: 1. The invention solves the problem that most existing mobile phone holders can only fix the phone in a certain position on the table. When the short video shooter moves in front of the table, the face is easy to move out of the phone screen, requiring frequent manual adjustment of the phone angle, which leads to inconvenience in the shooting process and affects the video quality. The invention enables the mobile phone holder to automatically follow the angle of the shooter's face, and can move back and forth to adjust the framing range, while obtaining stable support during the adjustment process, thereby improving the ease of operation and the quality of shooting videos.

[0015] 2. This invention utilizes a steering mechanism. The face-tracking camera continuously identifies the user's facial position and transmits offset electrical signals to a first controller in real time. After analysis, the controller drives a self-locking motor to rotate in both directions. Through bevel gear meshing, this drives a rotating rod and a connecting plate to rotate, causing the phone body on the clamping mechanism to rotate horizontally. This achieves automatic adjustment of the shooting angle. Simultaneously, the self-locking motor automatically locks after adjustment, fixing the shooting angle. This mechanism can adapt to the user's movement in real time, eliminating the need for manual adjustment and improving ease of operation. After adjustment, it stabilizes the shooting angle, preventing camera displacement and ensuring the continuity and stability of the captured image.

[0016] 3. The invention employs an adjustment mechanism where a motor drives a first screw to rotate. This causes the mounting housing to move linearly back and forth along the surface of the first screw, guided by a slider and a groove. A fixed partition and bearing inside the mounting housing limit and support the rotating rod, ensuring its stability during rotation. The rotating rod also moves back and forth with the mounting housing, thus moving the entire phone body forward and backward. This allows the viewfinder to zoom in or out, enriching the image content. This mechanism also eliminates the need for manual movement of the phone body, increasing the functionality of the solution and expanding its adaptability to various shooting scenarios.

[0017] 4. The invention employs an auxiliary support mechanism with two interlocking gears distributed vertically. The top interlocking gear is fixedly connected to the front end of the first screw. When the first screw rotates, it drives the bottom interlocking gear and the second screw to rotate synchronously, thereby driving the support plate to move back and forth. The support plate drives the bottom extension plate and the auxiliary wheels at both ends to move synchronously. The auxiliary wheels always roll in contact with the tabletop, providing stable support for the column, mounting shell, and frame during the adjustment of the phone body. Sharing the same power source with the adjustment mechanism, synchronous adjustment can be completed without additional drive, resulting in strong linkage and saving manufacturing costs. At the same time, it effectively distributes the pressure on the upper phone body and clamping mechanism, avoiding the problem of the rear end of the device being suspended and the center of gravity being too far back, which could lead to tipping over and damage to the phone body. This improves the stability during the adjustment process, prevents significant shaking of the shooting image, and ensures the quality of the final image.

[0018] 5. The invention incorporates a clamping mechanism. During use, pressing down on the pressure block moves the pressure rod and push rod downwards. The push rod's ends press against the inclined surfaces of the movable plates, using the inclined plane transmission principle to push the two movable plates to slide to both sides and stretch the tension springs, causing the side plates to open. After placing the phone body between the side plates, pulling up on the pressure block causes the tension springs to retract, resetting the movable plates. This allows the side plates to clamp the phone body tightly through the rubber pads. The upright plate is then fixed to the top of the connecting plate and can rotate synchronously with the steering mechanism. This mechanism significantly improves the ease of assembling and disassembling the phone body, adapting to different phone body sizes and offering strong versatility. Simultaneously, the rubber pads provide flexible clamping force, preventing the phone body from shifting or falling off during device rotation and displacement adjustments, ensuring a safe and reliable shooting process.

[0027] Specifically, it enables the phone holder to automatically follow the angle of the photographer's face, while also allowing for back-and-forth movement to adjust the framing range and provide stable support during adjustment, thereby improving ease of operation and video quality.

[0028] A curved plate 32 is fixedly installed on both the left and right sides of the column 1. A contact element 33 is provided above the curved plate 32. The bottom end of the contact element 33 extends through to the bottom of the curved plate 32 and is fixedly connected to a suction cup 34. The curved plate 32 is made of iron, and the contact element 33 is made of magnet. The inner wall of the curved plate 32 and the surface of the contact element 33 are attracted to each other. Pressing the contact element 33 causes the bottom suction cup 34 to press against the table, expelling the air inside the suction cup 34. Atmospheric pressure is used to firmly attach the suction cup 34 to the table surface, limiting and fixing the column 1, base 2, and frame 3 as a whole. The symmetrical arrangement of the suction cups 34 on both sides enhances the adsorption effect. The suction cups 34, together with the auxiliary support mechanism, significantly improve the stability of the fixed bracket compared to the traditional placement bracket. The magnetic structure ensures that the suction cups 34 will not move around when not in use and can be stably suspended below the curved plate 32 without contacting the table, facilitating the movement of the equipment.

[0031] Specifically, by setting the second embodiment, the camera can adapt to the photographer's movement in real time and drive the mobile phone body 5 to rotate at the corresponding angle. This eliminates the need for manual adjustment by staff, improving ease of operation. After adjustment, the shooting angle can be stabilized to prevent camera position shift.

[0032] Furthermore, the face tracking camera 6 continuously identifies and locates the subject's face position, and transmits the displacement offset electrical signal to the first controller 7 in real time.

The clamping mechanism includes a vertical plate 23, with a movable cavity 24 opened on the inner side of the vertical plate 23. Two opposing movable plates 25 are slidably connected to the inner wall of the movable cavity 24 via a slider and a groove. An inclined surface is provided on one side of each movable plate 25 facing away from the other. One side of each movable plate 25 extends to the outer side of the movable cavity 24. A side plate 26 is fixedly installed on the front side of each movable plate 25, and a rubber pad 27 is fixedly installed on one side of each side plate 26. One side of the pad 27 abuts against the mobile phone body 5. Tension springs 28 are fixedly installed on the opposite sides of the two movable plates 25. A pressure block 29 is provided on the top of the upright plate 23. A pressure rod 30 is fixedly installed on the bottom of the pressure block 29. The bottom end of the pressure rod 30 passes through the inner side of the movable cavity 24 and is fixedly connected to a push rod 31. The surface of the pressure rod 30 is slidably connected to the inner wall of the upright plate 23. The left and right ends of the push rod 31 are slidably in contact with the inclined surface on the movable plate 25. The upright plate 23 is fixedly installed on the top of the connecting plate 11.

[0045] Specifically, by setting the fourth embodiment, the upright plate 23 is fixed to the top of the connecting plate 11 and can rotate and move synchronously with the steering mechanism, which improves the ease of disassembling and assembling the mobile phone body 5, adapts to mobile phone body 5 devices of different sizes, has strong versatility, and the mobile phone body 5 will not have any problems of displacement or falling off during the rotation and displacement adjustment of the device.

[0046] Furthermore, when fixing the phone body 5, press down on the top pressure block 29, causing the pressure rod 30 and push rod 31 to move downward. The two ends of the push rod 31 press against the inclined surface of the movable plate 25. Using the inclined surface transmission principle, push the two movable plates 25 to slide to both sides and stretch the tension spring 28, so that the two side plates 26 open. The phone body 5 can be placed between the two side plates 26. Then pull the pressure block 29 upward. The retraction force of the tension spring 28 drives the movable plate 25 to return to its original position, so that the two side plates 26 move inward and clamp the phone body 5 through the rubber pad 27.

[0047] Working principle: All structures used in this application can be additionally fitted with protective measures of common knowledge in the field of this technology in different usage environments, including but not limited to the following methods, such as protective components for equipment protection, dustproof nets for equipment dust prevention, and sealing components or waterproof coatings for equipment waterproofing, etc., which are commonly used by those skilled in the art.

[0048] When fixing the phone body 5, press down on the top pressure block 29, which will cause the pressure rod 30 and the push rod 31 to move downward. The two ends of the push rod 31 press against the inclined surface of the movable plate 25. Using the inclined surface transmission principle, the two movable plates 25 are pushed to slide to both sides and the tension spring 28 is stretched, so that the two side plates 26 are opened. The phone body 5 can be placed between the two side plates 26. Then, pull up the pressure block 29. The return force of the tension spring 28 will drive the movable plate 25 to reset, so that the two side plates 26 are inward and the phone body 5 is clamped by the rubber pad 27. The upright plate 23 is fixed to the top of the connecting plate 11 and can rotate and move synchronously with the steering mechanism, which improves the ease of assembling and disassembling the phone body 5. It is compatible with different sizes of phone body 5 devices and has strong versatility. During the rotation and displacement adjustment of the device, the phone body 5 will not have any problems of displacement or falling off. Pressing the contact part 33 causes the bottom suction cup 34 to press against the table, expelling the air inside the suction cup 34. Atmospheric pressure is used to firmly attach the suction cup 34 to the table surface, limiting and fixing the column 1, base 2 and frame 3 as a whole. The symmetrical arrangement of the suction cups 34 on both sides enhances the adsorption effect. The suction cups 34, together with the auxiliary support mechanism, greatly improve the stability compared to the traditional placement bracket. The magnetic structure ensures that the suction cups 34 will not move around when not in use and can be stably suspended under the curved plate 32 without contacting the table, making it convenient to move the equipment. The face tracking camera 6 continuously identifies and locates the user's face position and transmits the displacement offset electrical signal to the first controller 7 in real time. The first controller 7 has a built-in preset program that calculates and analyzes the offset signal and outputs drive commands to control the start, stop, and forward / reverse rotation of the self-locking motor 8. The self-locking motor 8 drives the first bevel gear 9 at the output end to rotate, which in turn drives the second bevel gear 12 to drive the rotating rod 10 to rotate synchronously. The connecting plate 11 at the top of the rotating rod 10 carries the upper clamping mechanism and the mobile phone body 5, thereby driving the mobile phone body 5 to rotate horizontally as a whole, realizing the adjustment of the shooting angle. The self-locking motor 8 can automatically lock after adjustment to fix the shooting angle. The through-slot structure provides space for motor installation and movement avoidance, and can adapt to the user's own movement in real time, driving the mobile phone body 5 to rotate at the corresponding angle. No manual adjustment is required, improving the convenience of operation. After adjustment, the shooting angle can be stabilized to prevent the camera position from shifting. When it is necessary to enrich the content of the captured image, the second controller 17 controls the forward and reverse rotation of the adjustment motor 13. The adjustment motor 13 drives the first screw 14 to rotate, which in turn drives the mounting housing 15 to move back and forth linearly along the surface of the first screw 14 with the cooperation of the slider and the slide groove. The partition 16 and bearing structure fixed inside the housing limit and support the rotating rod 10, so that the rotating rod 10 of the steering mechanism is stable when rotating. At the same time, it moves back and forth with the mounting housing 15, so that the mobile phone body 5 can move back and forth, and the viewfinder lens can be pulled further away, so that more content can appear in the picture. It is also possible to move the mobile phone body 5 manually, which increases the functionality of this technical solution. When the first screw 14 rotates, the top linkage gear 18 rotates synchronously with the first screw 14, which in turn drives the bottom linkage gear 18 and the second screw 19 to rotate synchronously. The rotation of the second screw 19 drives the support plate 20 to move back and forth. The support plate 20 drives the bottom extension plate 21 and the auxiliary wheels 22 at both ends to move synchronously. The auxiliary wheels 22 always roll in contact with the table. During the back and forth adjustment of the mobile phone body 5, the support plate 20 moves synchronously with the mobile phone body 5, providing support for the column 1, the mounting shell 15, and the frame 3. It shares the same power with the adjustment mechanism, and can complete the synchronous adjustment of the auxiliary support structure without an additional power source, demonstrating strong linkage. This design saves manufacturing costs, and the auxiliary support can effectively share the pressure of the upper mobile phone body 5 and the clamping mechanism, avoiding the problem of the device being suspended at the rear and the center of gravity being too far back, which could cause it to tip over and break the mobile phone body 5. It also improves the stability of the device during adjustment, prevents the shooting image from shaking significantly, and ensures the quality of the final product. The dustproof cloth 35 is made of flexible and stretchable material and covers the top of the frame 3. When the mounting shell 15 moves forward with the first screw 14, the flexible dustproof cloth 35 can stretch along with it, covering the first and second screws 19 inside the device, reducing the impact of external dust. The protective cover 36 completely wraps around the two internal linkage gears 18, isolating them from external contact and interference from debris.

[0049] In summary, through the coordination of the steering mechanism, adjustment mechanism, auxiliary support mechanism, and clamping mechanism, the phone holder can automatically follow the angle of the photographer's face while moving back and forth to adjust the framing range, and obtain stable support during the adjustment process, thereby improving the ease of operation and the quality of video shooting.
