Description

Technical Field

[0001] The utility model relates to an auxiliary device for a camera used in large-scale photography, in particular to a camera extension device used for robot photography. Background Art

[0002] As people's living standards improve, their cultural lives become increasingly enriched, and movies and TV series have become more and more a part of people's daily lives and entertainment. However, unlike the micro-videos and short videos on Douyin and Kuaishou, the filming of these TV series and movies is a large-scale filming method, including large venues, crews, and related props. Therefore, traditional handheld cameras have long been abandoned. Currently, the most common use is to use robotic arms or robotic jibs to shoot large-scale performances or large-scale film shoots. By controlling the rapid and stable movement or rotation of the robotic arm, the camera or camera can be quickly moved horizontally, moved up and down, or flipped to shoot. In some special scenarios, the lower end of the robot arm needs to be able to swing up or down to hold the camera level and extend through a small window such as a car window for rotation or telescopic shooting. However, because existing cameras are directly mounted on the bottom of the robot arm, even if the arm bottom can swing, this swing is limited to approximately upward or downward, and the maximum range of left and right swing is 270 degrees, and it cannot rotate 360 ​​degrees without blind spots. At the same time, the lower half of the robot arm is blocked by the car window frame due to its tilted setting. In this case, the camera cannot reach through the car window to capture the interior of the car, nor can it enter a small indoor space through the window for local shooting. There is no way to achieve the camera rotation and / or zooming in and out of the car or small space. Currently, most of this shooting is done manually, but the effects of manual shooting, including rotation, zooming, and zooming, are significantly different from those achieved by the robot arm electronic design, resulting in poor viewing quality and final film quality.

[0003] Moreover, when using a robotic arm during filming, different cameras with different models or functions will be used according to the scene and needs, and different cameras need to be replaced on site. However, because the photography robot is relatively large, the bottom of the robot is relatively heavy and generally does not move, and the robot arm is located relatively high, it is very inconvenient to replace the camera. The screws on the camera need to be removed, and then the new camera needs to be installed on the bottom of the robot arm and adjusted. The first disadvantage of this is that it is more troublesome, requires many steps, and the replacement takes a long time. Because the preparation of the shooting scene includes the venue, personnel, props, and other related aspects, shortening the replacement time as much as possible has become an urgent problem to be solved.

[0007] The camera extension frame is an L-shaped frame, which includes a camera holder and an extension fixing plate. The extension fixing plate is vertically set at the rear end of the camera holder. The camera is detachably fixed below or above the camera holder, and the extension fixing plate is detachably fixed to the robot arm holder.

[0008] The extending fixing plate and the camera holder are detachably fixedly connected together via left and right side frames, and the side frames are detachably fixed to the left and right sides of the camera holder and the extending fixing plate, respectively.

[0009] The lower part of the camera holder is detachably fixed to the camera by a camera bolt. The camera holder is provided with at least one intermediate fixing groove. The middle part of the bottom of the intermediate fixing groove is provided with an intermediate slide running through the upper and lower parts. The screw of the camera bolt is located in the intermediate slide. The bolt head of the camera bolt is slidably provided in the intermediate fixing groove. The camera bolt passes through the intermediate fixing groove and the intermediate slide from top to bottom and is detachably fixed to the camera.

[0010] At least one side adjustment slot is also provided on the camera holder, and the side adjustment slot is located on one side or both sides of the middle fixing slot, and an angle is formed between the extension line of the side adjustment slot and the extension line of the middle fixing slot. A side slide running through the top and bottom is provided at the center of the bottom of the side adjustment slot, and the screw of the camera bolt is located in the side slide, and the bolt head of the camera bolt is slidably provided in the side adjustment slot, and the camera bolt passes through the side adjustment slot and the side slide from top to bottom and is detachably fixed to the camera.

[0011] The rear portion of the camera extension frame is fixedly connected to the robot arm holder in a quick-detachable manner via a quick-detachable connector.

[0012] The quick-disconnect connector includes a connector and a quick-installation strip arranged on one side of the connector. The connector is detachably fixedly connected to the rear portion of the camera extension frame, and the quick-installation strip is detachably fixedly connected to the robot arm holder.

[0013] The quick installation strip is detachably fixedly connected to the outer side of the robot arm fixer via a quick installation bolt or is fixedly connected via a detachable buckle.

[0014] A first quick-release threaded hole is provided on the outside of the robot arm fixer, and a second quick-release threaded hole or a second quick-release through hole is provided on the quick-release strip. The quick-release bolt is threadedly connected to the second quick-release threaded hole or the second quick-release through hole and the first quick-release threaded hole in sequence to quickly and detachably fix the quick-release strip to the robot arm fixer.

In this way, the camera extension bracket extending toward the front switches the connection position of the camera from the bottom of the robot arm to the front of the bottom of the robot arm and advances it forward a certain distance, generally 10-20 cm. After extending forward, since the camera is detachably fixed on the camera extension bracket, and the camera extension bracket increases the distance between the camera and the rotation point, the swing amplitude is larger, and the robot arm holder is detachably and rotatably connected to the bottom front end of the robot arm. The camera can be extended into the car or a small space through the car window and small window to perform multi-angle shooting and 360° rotation shooting without dead angles, and can continuously change long focal length and short focal length shooting, etc. The robot arm located behind the camera extension bracket does not need to be extended into the car window or small window, and the robot arm will not bump into the edge of the car window or small window and cause damage, thereby expanding the shooting range, shooting angle and shooting form, so that the camera shooting is no longer restricted. Therefore, the advantages of the camera extension device for robot shooting in the present invention over the existing technology are: relatively simple structure, small size, light weight, and the ability to send the camera installed thereon through car windows and small windows to the maximum extent into the car or small space to complete rotational shooting without dead angles in the car or small space, thereby expanding the shooting range and application scenarios of the robot arm.

[0033] The present invention will be further described in detail below with reference to the accompanying drawings and in combination with specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0034] This utility model is a camera extension device for robot photography, please refer to Figures 1 to 9The relevant figures include: a camera extension frame 18 extending toward the front and a robot arm holder 2, the camera extension frame 18 extending from front to back, the camera 8 for shooting can be detachably fixed on the camera extension frame 18, the rear portion of the camera extension frame 18 can be detachably fixed to the robot arm holder 2, and the robot arm holder 2 can be detachably rotatably connected to the bottom front end of the robot arm 17. In this way, the camera extension frame 18 extending forward will switch the connection position of the camera 8 from the bottom of the robot arm 17 to the front of the bottom of the robot arm 17 and advance forward a certain distance, generally 10-20 cm. After extending forward, since the camera 8 is detachably fixed on the camera extension frame 18, and the camera extension frame 18 increases the distance between the camera 8 and the rotation point, the swing amplitude is larger, and the robot arm holder 2 is detachably and rotatably connected to the bottom front end of the robot arm 17, the camera 8 can be completely extended through the car window and small window into the car or a small space to perform multi-angle shooting and 360° rotation shooting without blind spots, and can continuously change long focal length and short focal length shooting, etc., and the robot arm 17 located behind the camera extension frame 18 does not need to be extended into the car window or small window, and the robot arm 17 will not bump into the edge of the car window or small window and cause damage, thereby expanding the shooting range, shooting angle and shooting form, so that the camera 8 is no longer restricted. Therefore, the advantages of the camera extension device for robotic filming of the present invention over existing technologies include: a relatively simple structure, compact size, and light weight. It allows the mounted camera 8 to be inserted through car windows and small windows into a vehicle or small space to the greatest extent possible, achieving seamless rotational filming within a vehicle or small space, thereby expanding the filming range and application scenarios of the robotic arm 17. In the aforementioned technical solution, the specific structure can be a swing arm 21 disposed at the bottom of the robotic arm 17, capable of swinging back and forth through a certain angle, with the robotic arm holder 2 detachably mounted on the swing arm 21. In this way, the camera extension frame 18, the robotic arm holder 2, and the swing arm 21 enable the camera 8 to swing at different angles, achieving 360° seamless rotational filming within a vehicle or small space. Specifically, a rotator 22 can be provided between the swing arm 21 and the robot arm fixer 2. The rotator can be detachably fixed on the swing arm 21 and can rotate 360° without dead angles. The robot arm fixer 2 can be detachably provided on the rotator 22, so that the rotator 22 can drive the robot arm fixer 2 to rotate 360° without dead angles.

[0035] This utility model is a camera extension device for robot photography, please refer to Figures 1 to 9In the relevant figures, based on the previous technical solution, the camera extension frame 18 can also be L-shaped. The camera extension frame 18 includes a camera holder 1 and an extension fixing plate 19. The extension fixing plate 19 is vertically arranged at the rear end of the camera holder 1. The camera 8 can be removably fixed below or above the camera holder 1. The extension fixing plate 19 is removably connected to the robot arm holder 2. This L-shaped frame is convenient for carrying the camera 8 and extending through car windows or small openings to enter cars or small spaces for filming. The robot arm 17 outside will not hit the car windows or windows and be interfered with by the car windows or windows. Specifically, the horizontal arrangement of the camera holder 1 facilitates the removable installation of the camera 8 above or below it, providing support for the camera 8 and driving the camera 8 to move back and forth or rotate. The vertically positioned extension plate 19 primarily functions to shift the mounting angle of the robot arm 17 and the camera 8 to a perpendicular position, rather than the existing commercially available arrangement where the camera 8 is mounted directly below the robot arm 17. This arrangement prevents the camera 8 from reaching into a car or a small space for filming because the robot arm 17 is blocked by the window frame. Because the camera extension bracket 18 shifts the angle of the camera 8 and mounts it a certain distance in front of the bottom of the robot arm 17, the camera 8's filming range is expanded, allowing it to penetrate through a car window or small window into a car or a small space for full-angle, rotatable filming. The present invention's camera extension device for robotic filming, based on the previous technical solution, may further comprise: the extension plate 19 and the camera holder 1 are detachably connected by left and right side frames 20, each of which is detachably secured to the camera holder 1 and the extension plate 19. The side frames 20 on one or both sides thus removably secure the extension plate 19 and the camera holder 1 together to form an L-shaped frame. This facilitates the reversible installation of the camera 8 at the front extension position directly below the robot arm 17, thereby enabling the camera 8 to penetrate through a car window or small opening into a car or a narrow space for filming. A further preferred embodiment of the camera extension device for robotic filming of the present invention is that the side frames 20 are removably secured to the camera holder 1 and the extension plate 19 via frame bolts. This securement with frame bolts provides a more secure connection and facilitates the removal and replacement of camera holders 1 of different sizes.

[0036] This utility model is a camera extension device for robot photography, please refer to Figures 1 to 9In the relevant figures, based on the previous technical solution, the lower portion of the camera holder 1 can also be removably secured to the camera 8 via a camera bolt. The camera holder 1 is provided with at least one intermediate fixing slot 10. A middle slideway 11 is provided at the bottom center of the intermediate fixing slot 10, extending from top to bottom. The screw of the camera bolt is located within the middle slideway 11, and the head of the camera bolt slides within the intermediate fixing slot 10. The camera bolt passes through the intermediate fixing slot 10 and the middle slideway 11 from top to bottom and is removably secured to the camera 8. This intermediate fixing slot 10 reduces weight while also securing the camera 8. The middle slideway 11 of the intermediate fixing slot 10 allows the screw of the camera bolt to slide within the middle slideway 11 to adjust the position of the camera 8. The head of the camera bolt is located within the larger portion. After being inserted into the intermediate fixing slot 10 and then passed through the middle slideway 11, the camera bolt is secured to the top of the camera 8. Of course, a further preferred technical solution is to provide two intermediate fixing slots 10, one located on the front and rear sides of the camera holder 1. This allows the camera to be fixed to the camera holder 1 at a position determined by the size and dimensions of the camera. A further preferred technical solution is to provide a bolt-locking hole 12 at the head end of each intermediate fixing slot 10. The inner wall of each bolt-locking hole 12 is internally threaded and communicates with the intermediate slideway 11. This allows the camera bolt to be inserted from this location. Because the hole is larger than the intermediate slideway 11, it is easier to insert the bolt. The internal threads on the inner wall of the bolt-locking hole 12 prevent the bolt from slipping and falling out, allowing the bolt to be locked into the internal threads.

[0037] This utility model is a camera extension device for robot photography, please refer to Figures 1 to 9In the relevant figures, a further preferred technical solution based on the previous technical solution is: at least one side adjustment groove 13 is further provided on the camera holder 1, and the side adjustment groove 13 is located on one side or both sides of the middle fixed groove 10, and there is an angle between the extension line of the side adjustment groove 13 and the extension line of the middle fixed groove 10, and a side slide 14 running through the top and bottom is provided at the center of the bottom of the side adjustment groove 13, and the screw of the camera bolt is located in the side slide 14, and the bolt head of the camera bolt is slidably provided in the side adjustment groove 13, and the camera bolt passes through the side adjustment groove 13 and the side slide 14 from top to bottom and is detachably fixed to the camera 8. This arrangement is intended to expand the applicability of the camera holder 1. Because the camera 8 may have one or two threaded mounting holes, and because the spacing of the mounting holes on cameras 8 varies depending on the model and brand, the side adjustment slots 13 are provided, and the side slides 14 are positioned at the center of the bottom of the side adjustment slots 13. Furthermore, the side adjustment slots 13 and the middle slides 11 are not parallel, i.e., their extensions form an angle. Thus, if there are two mounting holes, the camera 8 can be removably secured to the camera holder 1 by sliding the camera bolt within the middle slides 11 and the side slides 14. This allows for the installation of cameras with mounting holes at different spacings. A more preferred technical solution is one in which the side adjustment slots 13 are provided on both sides of the middle fixing slot 10. This allows the camera 8 to be conveniently and securely removably secured to the camera holder 1 by sliding the camera bolt within the side slides 14 on both sides. A further preferred technical solution is to provide a bolt-proof hole 15 at the head end of the side adjustment slot 13. The inner wall of the bolt-proof hole 15 is internally threaded and communicates with the side slideway 14. The function of this bolt-proof hole 15 is similar to that of the bolt-proof hole 12 described above: it facilitates the insertion of the camera bolt and prevents it from falling. The camera 8 can be detachably mounted on the camera holder 1 in any desired orientation, with the lens facing forward, left, or right, as long as the desired shooting position is achieved.

[0038] This utility model is a camera extension device for robot photography, please refer to Figures 1 to 9In the relevant figures, a further preferred technical solution based on the previous technical solution is that the camera holder 1 is provided with vertically extending weight-reducing holes 16. The purpose of weight-reducing holes 16 is to further reduce the weight of the camera holder 1, making it as lightweight and compact as possible, and facilitating quick and easy replacement. A further preferred technical solution is that the weight-reducing holes 16 are evenly distributed throughout the camera holder 1, thereby achieving more uniform weight reduction and preventing localized excessive wear caused by stress concentration.

[0039] This utility model is a camera extension device for robot photography, please refer to Figures 1 to 9 In the relevant figures, based on the previous technical solution, it can also be that the rear portion of the camera extension frame 18 is quickly and detachably fixedly connected to the robot arm holder 2 via a quick-detachable connector 3. In this way, multiple cameras 8 (of different models and functions) on site need to be rotatably installed at the forward extension position directly in front of the robot arm 17 when needed. Each camera 8 of different models and functions is detachably fixedly connected to a camera extension frame 18, and the camera extension frame 18 is detachably fixedly connected to the quick-detachable connector 3, while the robot arm holder 2 is detachably and rotatably connected to the bottom front end of the robot arm 17. When quick installation is required, the quick-detachable connector 3 and the robot arm holder 2 can be directly and quickly fixed. When a different camera 8 needs to be replaced, the quick-detachable connector 3 on the camera extension frame 18 to which the used camera 8 is fixed is directly removed from the robot arm holder 2. The robot arm 17 is also fixed with the robot arm holder 2, which does not need to be disassembled. The camera 8 that has been used can be directly removed from the camera extension frame 18 with the quick-release connector 3 and placed aside. Since the second camera 8 needed before shooting has already been installed on the second camera extension frame 18, and the camera extension frame 18 is also equipped with the second quick-release connector 3, the quick-release connector 3 can be quickly installed on the robot arm holder 2 to complete the quick disassembly and switching of different cameras 8. Because the camera extension device for robot shooting of the present invention is relatively simple in structure, relatively small in size, and relatively light in weight, all required cameras 8 can be installed on the camera extension frame 18 before shooting begins, and the quick-release connector 3 can be installed on the camera extension frame 18, so that they can be directly used for quick installation, which can maximize time savings, save a lot of money and expenses, and effectively improve shooting efficiency.

[0040] This utility model is a camera extension device for robot photography, please refer to Figures 1 to 9In the relevant figures, based on the previous technical solution, the quick-disconnect connector 3 may also include a connector 4 and a quick-installation bar 5 fixed to one side of the connector 4. The connector 4 is removably fixedly connected to the rear portion of the camera extension frame 18, and the quick-installation bar 5 is removably fixedly connected to the robot arm holder 2. In this way, at the filming location, the connector 4 can be first removably fixedly connected to the camera extension frame 18, to which the camera 8 is already fixedly connected. Then, the connector 4 and the quick-installation bar 5 can be removably fixedly connected or integrally formed. When quick disassembly is required, the quick-installation bar 5 can be quickly removed from the bottom of the robot arm 17, and then the camera extension frame 18, with the camera 8 already fixedly installed, along with the connector 4 and the quick-installation bar 5, can be quickly installed at the bottom front end of the robot arm 17. This can save approximately 1 / 10 of the time required for conventional replacement. This allows for quick disassembly and assembly, while being compact, lightweight, and cost-effective. Based on the previous technical solutions, the camera extension device for robot photography of the present invention may further include a preferred technical solution in which the connector 4 is detachably fixedly connected to the camera extension frame 18 via connecting bolts. Connecting holes are provided through the connector 4, and the connecting bolts are screwed into the bottom of the connecting bolts, which are then screwed onto the camera extension frame 18. This ensures a secure and removable connection, facilitates installation and removal, and is relatively cost-effective. Furthermore, multiple connecting bolts may be provided on the connector 4, and these bolts may be evenly distributed throughout the connector 4, ensuring a more secure fixation and evenly distributing force, thereby preventing unsafe situations such as excessive wear caused by uneven localized force, which could result in the camera falling.

[0041] In addition to the above technical solutions, the camera extension device for robot photography of the present invention can also be further preferably configured such that the quick-installation bar 5 is removably fixed to the outer side of the robot arm holder 2 via a quick-install bolt or a removable snap fastener. In this way, the quick-installation bar 5 and the robot arm holder 2 are fixed together by the quick-installation bolt or the removable snap fastener, achieving a quick and secure removable connection. Alternatively, a plug-and-lock method can be used, as long as the quick-installation bar 5 and the robot arm holder 2 can be quickly removed and quickly fixed. A more efficient method is to removably fasten the quick-installation bar 5 and the robot arm holder 2 together using a single quick-installation bolt. Compared to the conventional method of directly fixing the camera 8 to the bottom of the robot arm 17, which is awkward and difficult to apply force, the quick-installation bar 5 of the camera extension device for robot photography of the present invention is directly attached to the outer side of the robot arm holder 2. Therefore, the point of force is at the outermost edge, making installation easier and faster. At the same time, it can solve the problem of too long assembly and disassembly time caused by too many points that need to be fixed, and it is faster, more convenient, and the installation position is convenient for installation. On the basis of the previous technical solution, a further preferred technical solution is: the outside of the robot arm fixer 2 is provided with a first quick-install threaded hole 6, and the quick-installation bar 5 is provided with a second quick-installation threaded hole 7 or a second quick-installation through-hole, and the quick-installation bolt is threadedly connected to the second quick-installation threaded hole 7 or the second quick-installation through-hole and the first quick-installation threaded hole 6 in sequence, and then the quick-installation bar 5 is quickly and detachably fixed to the robot arm fixer 2. In this way, the quick-installation bolt passes through the second quick-installation threaded hole 7 or the second quick-installation through-hole from the outside to the inside, and then passes through the first quick-installation threaded hole 6 and is threadedly connected to the outside of the robot arm fixer 2. In this way, the quick-installation bolt can be quickly disassembled and assembled using one quick-installation bolt, and the fixation is relatively firm.

[0042] This utility model is a camera extension device for robot photography, please refer to Figures 1 to 9In the relevant figures, a further preferred technical solution based on the previous technical solution is: a rearward-concave robot arm fixing slot 9 is provided at the front of the robot arm fixer 2, and the shape and size of the connector 4 correspond to the robot arm fixing slot 9, and the connector 4 is aligned and embedded in the robot arm fixing slot 9. In this way, because the shape and size of the connector 4 correspond to those of the robot arm fixing slot 9, the connector 4 can be directly inserted into the robot arm fixing slot 9 during the installation process. After the two are accurately aligned, the installation position of the quick installation strip 5 corresponds to the installation position of the robot arm fixer 2. This makes it more convenient to align quickly and accurately, and avoids wasting time moving back and forth to find the position during the alignment process. Based on the previous technical solution, the camera extension device for robot shooting of the present invention can also be further preferred. The technical solution can also be: the inward end size of the connector 4 is smaller than the external end size. In this way, when the connector 4 is inserted from the outside to the inside, the small end enters the robot arm fixing groove 9 first. Since the rear end of the robot arm fixing groove 9 is large, it is relatively easy to enter. Then the connector 4 is quickly and completely inserted into the robot arm fixing groove 9. Since the two are the same in shape and size, after being fully inserted, it is equivalent to being well embedded in the robot arm fixing groove 9, so that the connector 4 and the robot arm holder 2 are quickly and accurately aligned, and then the fixed connection is started. A further preferred technical solution is that the connector 4 is a box body with an open rear end, and the bottom of the box body is detachably fixedly connected to the camera holder 1. Because such a connector 4 is in the shape of a box body with a hollow middle, the outer wall of its periphery can fit well with the inner wall of the robot arm fixing groove 9 for embedded docking. At the same time, the hollow structure can greatly reduce the weight of the entire connector 4, making the entire device more lightweight.

[0043] This utility model is a camera extension device for robot photography, please refer to Figures 1 to 9 In the relevant figures, an alternative technical solution based on the previous technical solution is that the robot arm holder 2 is detachably fixed to the bottom of the robot arm 17 by at least three arm bolts. This fixing method is more convenient, more secure, and less expensive.

[0044] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0045] The above examples of the present invention are described in detail.
