Description

Technical Field

[0001] This utility model relates to the field of shooting auxiliary tools, and in particular to a short video shooting device for video promotion. Background Technology

[0002] In today's booming digital marketing landscape, video promotion, with its diverse formats including short videos, live streams, and long videos, has become a core tool for businesses to achieve brand exposure, user reach, and traffic conversion. However, the production of high-quality video content heavily relies on suitable shooting equipment, the selection of which requires a comprehensive consideration of factors such as shooting location, budget, creative needs, and expected results.

[0003] Currently, most short video shooting equipment on the market uses tripods or drones as support and fixation tools. This traditional fixing method has exposed many drawbacks in practical applications: First, it has poor mobility. When the shooting scene needs to be frequently changed or followed, moving the tripod is time-consuming and laborious, and drone operation is complex and greatly restricted by environmental factors, making it difficult to respond quickly to shooting needs. Second, the shooting angle adjustment is limited. The height and angle adjustment range of the tripod is limited, making it difficult to achieve special angles such as shooting from low to low, close to the ground, or shooting from high, high, overhead. Although drones can achieve high-altitude shooting, their control precision is insufficient when shooting at low altitudes or close distances, and there are safety risks. These limitations result in a single shooting angle and incomplete scene coverage, failing to meet creators' pursuit of diverse and immersive shooting effects, and greatly limiting the expressiveness and dissemination of video creation.

[0004] Therefore, there is an urgent need to develop a video shooting device that is easy to move flexibly and can be freely adjusted from multiple angles to improve shooting efficiency and image quality, and meet the growing demand for high-quality video creation in the digital marketing field.

[0022] The present invention will be further described below with reference to the accompanying drawings:

[0023] like Figures 1-6 As shown, this embodiment provides a short video shooting device for video promotion, including a remote-controlled intelligent mobile frame 1, which serves as the mobile carrier of the entire shooting device. A battery controller 2 is embedded inside the remote-controlled intelligent mobile frame 1, mainly used to manage and control the power supply of the internal battery. Support mounting plates 3 are provided on both sides of the remote-controlled intelligent mobile frame 1, providing a stable mounting platform for the angle adjustment structure 4. An angle adjustment structure 4 is installed on the upper end of the support mounting plate 3, its main function being to adjust the angle of the telescopic structure 5. The telescopic structure 5 is fixed between the angle adjustment structures 4, allowing the overall length of the device to be changed through extension and retraction, thereby adjusting the distance between the shooting device and the subject, adapting to different shooting distance requirements, and achieving effects such as long-distance shooting or close-up shooting. One end of the telescopic structure 5 is designed with a width adjustment structure 6, adjusting the distance between the clamping and fixing claws 8 to adapt to the clamping needs of shooting devices of different sizes, improving the device's versatility. Directional adjustment motors 7 are installed on both sides of the width adjustment structure 6, driving the clamping and fixing claws 8 to rotate, thereby changing the shooting direction of the clamped shooting device. The output end of the directional adjustment motor 7 is fixedly installed with clamping and fixing claws 8 for clamping and fixing the shooting device.

[0024] The angle adjustment structure 4 includes an angle adjustment mounting shaft 401. A rotating mounting hole is provided at the upper end of the support mounting plate 3. The angle adjustment mounting shaft 401 is rotatably engaged inside the rotating mounting hole. A positioning mounting plate 402 is fixedly installed between the angle adjustment mounting shafts 401. A lever gear 403 is fixedly welded to the outside of the angle adjustment mounting shaft 401. An angle adjustment motor 404 is embedded and installed on the outside of the support mounting plate 3. An angle adjustment gear is fixedly installed at the output end of the angle adjustment motor 404. The angle adjustment gear and the lever gear 403 mesh with each other. By controlling the angle adjustment motor 404, its output end drives the angle adjustment gear to rotate. Because the angle-adjusting gear and the lever gear 403 mesh with each other, the rotation of the angle-adjusting gear will drive the lever gear 403 to rotate, which in turn causes the angle-adjusting mounting shaft 401 to rotate within the rotating mounting hole. As the angle-adjusting mounting shaft 401 rotates, the positioning mounting plate 402 fixed between the angle-adjusting mounting shafts 401 will also rotate. The rotation of the positioning mounting plate 402 will drive the telescopic structure 5 to rotate together, thereby realizing the adjustment of the angle of the telescopic structure 5. During the adjustment process, the telescopic structure 5 can be ensured to reach the required shooting angle by observing the shooting screen or using an angle measuring tool. When the telescopic structure 5 is adjusted to the appropriate angle, the operation of the angle-adjusting motor 404 is stopped. Due to the meshing action between the gears and the cooperation between the angle-adjusting mounting shaft 401 and the rotating mounting hole, the telescopic structure 5 will remain at that angle position and will not rotate automatically, ensuring the stability of the angle during the shooting process. If it is found that the shooting angle needs to be finely adjusted during the shooting process, the angle-adjusting motor 404 can be restarted and the angle can be adjusted according to the above steps to meet the changes in different shooting scenarios and needs.

[0025] The telescopic structure 5 includes a telescopic threaded tube 501. A telescopic mounting hole is provided at the center of the positioning mounting plate 402. The telescopic threaded tube 501 is rotatably engaged inside the telescopic mounting hole. A transmission gear ring 502 is fixedly welded to one end of the telescopic threaded tube 501. A telescopic motor 503 is embedded in one side of the positioning mounting plate 402. A telescopic gear is fixedly installed at the output end of the telescopic motor 503. The telescopic gear meshes with the transmission gear ring 502. A foundation threaded rod 504 is installed on the internal threads of the telescopic threaded tube 501. A fixed connecting frame 505 is fixedly welded to one end of the foundation threaded rod 504. Foundation limiting rods 506 are fixedly welded to both sides of the fixed connecting frame 505. Limiting mounting holes are provided on both sides of the positioning mounting plate 402. The positioning rod 506 is slidably engaged inside the limiting mounting hole. The other end of the basic threaded rod 504 has a basic threaded groove. An extension threaded rod 507 is installed at the lower end of the basic threaded rod 504. One end of the extension threaded rod 507 has a connecting threaded rod, which is threadedly connected to the basic threaded groove. The other end of the extension threaded rod 507 has a connecting threaded groove, which is threadedly connected to the connecting threaded rod. The other end of the basic limiting rod 506 has a limiting threaded groove. One end of the basic limiting rod 506 has an extension limiting rod 508, which has a fixing threaded rod at one end, threadedly connected to the limiting threaded groove. The other end of the extension limiting rod 508 has an installation threaded groove. The threaded groove and the fixed threaded rod are connected by threads. Align the connecting thread of one extension threaded rod 507 with the base threaded groove of the base threaded rod 504, and rotate the extension threaded rod 507 to fix it to the base threaded rod 504 via threaded connection. If a longer telescopic structure 5 is needed, other extension threaded rods 507 can be connected sequentially in the same way, i.e., the connecting thread of the previous extension threaded rod 507 is threadedly connected to the connecting threaded groove of the next extension threaded rod 507. Align the fixed thread of one extension limiting rod 508 with the limiting threaded groove of the base limiting rod 506, and rotate the extension limiting rod 508 to fix it to the base limiting rod 506 via threaded connection. Similarly, if the length needs to be increased, it can be done sequentially. Other extension limiting rods 508 are spliced ​​together, that is, the fixed threaded rod of the previous extension limiting rod 508 is threadedly connected to the mounting threaded groove of the next extension limiting rod 508. The telescopic motor 503 is started, and the output end of the telescopic motor 503 drives the telescopic gear to rotate. Since the telescopic gear meshes with the transmission gear ring 502, the transmission gear ring 502 will drive the telescopic threaded tube 501 to rotate. During the rotation of the telescopic threaded tube 501, the basic threaded rod 504 can only move along the axial direction due to the limiting effect of the basic limiting rod 506 and the extension limiting rod 508. The basic threaded rod 504 will drive the fixed connecting frame 505 and other components connected to it to extend and retract together, thereby realizing the length adjustment of the entire telescopic structure 5. During the extension and retraction process...The telescopic structure 5 can be ensured to reach the required length by observing the shooting footage or using measuring tools. Once the telescopic structure 5 is adjusted to the appropriate length, the telescopic motor 503 should be stopped. Due to the friction and meshing between the threads, the telescopic structure 5 will remain at that length and will not automatically extend or retract, ensuring length stability during shooting. If fine-tuning of the telescopic length is needed during shooting, the telescopic motor 503 can be restarted, and the length can be adjusted according to the above telescopic operation steps to meet different shooting scenarios and requirements.

[0026] The width adjustment structure 6 includes a width adjustment bidirectional motor 601, which is embedded inside the fixed connection frame 505. A width adjustment threaded rod 602 is fixedly installed at the output end of the width adjustment bidirectional motor 601. L-shaped support plates 603 are slidably engaged at both ends of the fixed connection frame 505. A width adjustment threaded hole is provided on one side of the L-shaped support plate 603, and the threaded hole and the width adjustment threaded rod 602 are threadedly connected. When no width adjustment operation is performed, the width adjustment bidirectional motor 601 is in its initial position, and the L-shaped support plates 603 on both sides are in a relatively far or relatively close initial state. The specific position depends on the initial settings of the equipment and actual needs. The required clamping width is determined based on the size of the shooting equipment or other items to be clamped. If the item size is large, the clamping width needs to be increased; if the item size is small, the clamping width needs to be decreased. The width adjustment bidirectional motor 601 is then started, causing it to rotate in the predetermined direction. The output of the width-adjusting bidirectional motor 601 drives the width-adjusting threaded rod 602 to rotate. Since the width-adjusting threaded rod 602 is threadedly connected to the width-adjusting threaded hole of the L-shaped support plate 603, the L-shaped support plate 603 slides in opposite directions along the axial direction of the width-adjusting threaded rod 602 under the constraint of the fixed connecting frame 505. As the L-shaped support plates 603 move in opposite directions, the distance between the two L-shaped support plates 603 gradually increases, and the clamping width also increases accordingly. If it is necessary to reduce the clamping width, the width-adjusting bidirectional motor 601 is started, causing it to rotate in the opposite direction to the increase in width. The width-adjusting bidirectional motor 601 drives the width-adjusting threaded rod 602 to reverse direction, and the L-shaped support plates 603 slide towards each other along the axial direction of the width-adjusting threaded rod 602 under the constraint of the fixed connecting frame 505. As the L-shaped support plates 603 move towards each other, the distance between the two L-shaped support plates 603 gradually decreases, and the clamping width also decreases accordingly. During the width adjustment process… The relative position of the shooting equipment or other items with the L-shaped support plate 603 can be observed, or the clamping width can be measured using a measuring tool. The rotation of the width-adjusting bidirectional motor 601 can be adjusted in real time until the required clamping width is achieved. Once the clamping width is adjusted to the appropriate position, the shooting equipment or other items to be clamped can be placed between the L-shaped support plates 603 on both sides. Due to the support and clamping effect of the L-shaped support plates 603, the items can be stably fixed on the width-adjusting structure 6. If the clamping width is found to be unsuitable during shooting or use, the width-adjusting bidirectional motor 601 can be restarted at any time, and the adjustment can be carried out according to the above-mentioned width adjustment operation steps to meet the needs of different stages. After shooting or use is completed, the width-adjusting bidirectional motor 601 can be restarted again to make the L-shaped support plates 603 on both sides move in opposite directions, increasing the clamping width, thereby releasing the shooting equipment or other items, and then removing them from the width-adjusting structure 6.

[0027] The clamping and fixing claw 8 includes a mirror-image limiting rail 801, which is fixedly installed at the output end of the directional motor 7. A bidirectional mirror motor 802 is embedded inside the mirror-image limiting rail 801. A mirror screw 803 is fixedly installed at the output end of the bidirectional mirror motor 802. T-shaped anti-slip plates 804 are slidably engaged at both ends of the mirror-image limiting rail 801. One end of the T-shaped anti-slip plate 804 has a mirror-image threaded hole, which is threadedly connected to the mirror screw 803. When the shooting device is not clamped, the bidirectional mirror motor 802 is in its initial position, and the T-shaped anti-slip plates 804 on both sides... At a relatively far distance, leaving sufficient space for the filming equipment, place the filming equipment to be clamped between the two T-shaped anti-slip plates 804, ensuring the filming equipment is properly positioned for subsequent clamping operations. Start the bidirectional mirror motor 802, causing it to rotate in a predetermined direction. The output end of the bidirectional mirror motor 802 drives the mirror screw 803 to rotate. Since the mirror screw 803 is threadedly connected to the mirror threaded hole of the T-shaped anti-slip plate 804, the T-shaped anti-slip plate 804 will slide towards each other along the axial direction of the mirror screw 803 under the constraint of the mirror limit rail 801. Moving towards each other, they gradually approach the shooting device and eventually clamp it. During clamping, the anti-slip surface of the T-shaped anti-slip plate 804 increases the friction between it and the shooting device, ensuring that the shooting device is firmly fixed on the clamping claw 8. If the direction of the shooting device needs to be adjusted during shooting, the directional motor 7 can be rotated. The directional motor 7 drives the mirror limit rail 801 to rotate, thereby causing the entire clamping claw 8 and the shooting device to rotate together, thus changing the shooting direction. If the size of the shooting device changes or the clamping tightness needs to be readjusted, it can be restarted. The bidirectional mirror motor 802 rotates forward or backward as needed to adjust the distance between the two T-shaped anti-slip plates 804 to achieve a suitable clamping effect. After shooting is completed, the bidirectional mirror motor 802 is started to rotate in the opposite direction to the clamping. The bidirectional mirror motor 802 drives the mirror screw 803 to reverse. The T-shaped anti-slip plates 804 will slide back and forth along the axis of the mirror screw 803 under the constraint of the mirror limit rail 801. As the T-shaped anti-slip plates 804 move back and forth, they will gradually move away from the shooting device and eventually release the shooting device. At this time, the shooting device can be removed from the clamping and fixing claw 8.
