A support seat is fixedly connected to the lower end of the support cylinder. A worm is rotatably connected between the support seat and the bottom wall of the support cylinder through a bearing. All three worm gears are meshed with the worm to achieve synchronous position adjustment of the three support rods.

[0008] Furthermore, the support mechanism also includes a knob, which is fixedly connected to the lower end of the worm gear to provide driving force for the rotation of the worm gear.

[0009] Furthermore, a lithium battery is installed at the lower end of the shooting platform, and a controller is installed at the upper end of the shooting platform. The input terminal of the controller is electrically connected to the output terminal of the lithium battery to control various electrical appliances.

[0010] Furthermore, a three-axis mechanical stage is provided at the upper end of the shooting platform, and a camera is provided at the upper end of the three-axis mechanical stage. The input end of the three-axis mechanical stage is electrically connected to the output end of the controller, and the camera is bidirectionally electrically connected to the controller, so as to realize the three-axis position state adjustment of the camera and effectively track the shooting object.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This embodiment provides a technical solution: a mobile video shooting device, including a shooting platform 1, a support cylinder 2 fixedly connected to the lower end of the shooting platform 1, a lithium battery 14 disposed inside the lower end of the shooting platform 1, a controller 15 disposed inside the upper end of the shooting platform 1, the input end of the controller 15 being electrically connected to the output end of the lithium battery 14, and also including a support mechanism 3.

[0022] Support mechanism 3 includes a gathering groove 31, a rotating shaft 32, a rotating seat 35, and a support rod 36. The gathering grooves 31 are evenly arranged inside the support cylinder 2. The lower end of each gathering groove 31 is rotatably connected to a rotating shaft 32. The middle of each rotating shaft 32 is fixedly connected to a rotating seat 35. The upper end of each rotating seat 35 is fixedly connected to a support rod 36 (the support rod 36 can be completely gathered inside the corresponding gathering groove 31 in the gathering state). Support mechanism 3 also includes a worm gear 33 and a worm 34. The worm gear 33 is fixedly connected to the middle of the rotating shaft 32. The worm gear 33 is located at... Inside the rotating seat 35, a support base 4 is fixedly connected to the lower end of the support cylinder 2. A worm gear 34 is rotatably connected between the support base 4 and the bottom wall of the support cylinder 2 via a bearing. Three worm wheels 33 are all meshed with the worm gear 34. The support mechanism 3 also includes a knob 37, which is fixedly connected to the lower end of the worm gear 34. The outer surface of the support cylinder 2 is provided with evenly distributed ribs 11, and the outer surface of the support rod 36 is fixedly connected with evenly distributed annular ribs 12. (When a person holds the support cylinder 2 and the rib support rod 36, the ribs 11 and the annular ribs 12 are raised relative to each other.) (Friction), the upper end of each support rod 36 is fixedly connected to a rubber sleeve 13 (the rubber sleeve 13 protects the support rod 36 and reduces the hard contact between the support rod 36 and the working surface). According to the length requirement of the support arm for mobile video shooting, the knob 37 is rotated. The rotation of the knob 37 drives the worm gear 34. The rotation of the worm gear 34 drives the three worm wheels 33 to rotate synchronously away from the central axis of the support cylinder 2. The outward rotation of the three worm wheels 33 drives the adjacent rotating shaft 32 to rotate away from the central axis of the support cylinder 2. The outward rotation of the rotating shaft 32 drives the adjacent rotating seat 35 to rotate away from the central axis of the support cylinder 2. Rotating away from the central axis of the support cylinder 2 causes the support rod 36 to rotate around the central axis of the vertically adjacent rotating shaft 32 in a direction away from the central axis of the support cylinder 2. When the support rod 36 rotates downward more than 90 degrees, the relative length of the support arm increases. When the support arm reaches the specified length, the operator stops rotating the knob 37. Then, the operator holds the support cylinder 2 or the support rod 36 to move the shooting platform 1, or places the end of the support rod 36 with the rubber sleeve 13 in the work area. The three support rods 36 achieve stable three-point support for the support cylinder 2 and the shooting platform 1.

[0023] The system includes: a three-axis mechanical stage 5 (which can be a V3 gimbal with orthogonal three-axis stabilization, supporting 360° yaw and 335° pitch adjustment, and using the iSteady9.0 stabilization algorithm to effectively counteract shaking, suitable for dynamic camera movement) on the upper part of the three-axis mechanical stage 5; a camera 6 on the upper part of the three-axis mechanical stage 5; an electrical connection between the input end of the three-axis mechanical stage 5 and the output end of the controller 15; and a bidirectional electrical connection between the camera 6 and the controller 15. The controller 15 controls the operation of the camera 6. After the camera 6 focuses on the subject, the controller 15 controls the operation of the three-axis mechanical stage 5. The rotation of the turntable of the three-axis mechanical stage 5 adjusts the horizontal angle of the camera 6, and the rotation of the robotic arm of the three-axis mechanical stage 5 adjusts the height and tilt angle of the camera 6. This allows the shooting stage 1 to effectively follow the subject during movement, enabling the shooting of the subject. The camera 6 transmits the shooting information to the signal receiving end of the controller 15 for video information storage.

[0024] Wherein: the lower end of the outer surface of the support cylinder 2 is provided with an internal thread 8, the lower end of the outer surface of the support cylinder 2 is fitted with a protective cylinder 7, the inner wall of the protective cylinder 7 is fixedly connected with an external thread 9, the internal thread 8 and the external thread 9 are threadedly connected, the center position of the lower surface of the protective cylinder 7 is fixedly connected with a support 10, the lower end of the support 10 is provided with a through hole, and when the protective cylinder 7 is rotated, under the action of the threaded connection of the internal thread 8 and the external thread 9, the protective cylinder 7 moves downward.

[0025] The working principle of the mobile video shooting device provided by this utility model is as follows: During operation, the operator first rotates the protective cylinder 7 according to the required length of the support arm for mobile video shooting. Under the threaded connection of the internal thread 8 and the external thread 9, the protective cylinder 7 moves downward. After the protective cylinder 7 completely leaves the support cylinder 2, the knob 37 is rotated. The rotation of the knob 37 drives the worm gear 34, which in turn drives the three worm wheels 33 to rotate synchronously away from the central axis of the support cylinder 2. The outward rotation of the three worm wheels 33 drives the adjacent rotating shaft 32 to rotate away from the central axis of the support cylinder 2. The outward rotation of the rotating shaft 32 drives the adjacent rotating seat 35 to rotate away from the central axis of the support cylinder 2. This causes the support rod 36 to rotate around the central axis of the vertically adjacent rotating shaft 32 away from the central axis of the support cylinder 2. When the support rod 36 rotates downwards by more than 90 degrees, the relative length of the support arm increases. When the support arm reaches the specified length, the operator stops rotating the knob 37. Then, the operator holds the support cylinder 2 or the support rod 36 to move the shooting platform 1, or places the end of the support rod 36 with the rubber sleeve 13 in the work area. The three support rods 36 provide stable three-point support for the support cylinder 2 and the shooting platform 1. The camera 6 is operated through the controller 15. After the camera 6 focuses on the subject, the controller 15 controls the operation of the three-axis mechanical table 5. The rotation of the turntable of the three-axis mechanical table 5 realizes the lateral angle adjustment of the camera 6, and the rotation of the mechanical arm of the three-axis mechanical table 5 realizes the height and tilt angle adjustment of the camera 6, so that the shooting platform 1 can effectively follow the subject during movement and realize the moving shooting of the subject.

[0026] It is worth noting that the three-axis mechanical stage 5 disclosed in the above embodiments can be a V3 gimbal, and the controller 15 controls the operation of the three-axis mechanical stage 5 and the camera 6 using methods commonly used in the prior art.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
