Description

Technical Field

[0001] This utility model relates to the field of broadcasting and film technology, and in particular to a camera for broadcasting and film shooting. Background Technology

[0002] Broadcasting is a medium that transmits audio and visual programs to a wide area via radio waves or wires. In a narrow sense, broadcasting uses only sound to transmit content, employing radio waves and wires. In a broader sense, broadcasting includes both audio-only broadcasting and television, which combines sound and images. Existing broadcast cameras capture images from fixed angles. If users need to photograph objects from multiple angles, multiple cameras need to be set up separately, increasing shooting costs. Utility Model Content

[0003] The purpose of this invention is to address the problems existing in the background technology by proposing a broadcast and film shooting camera that uses a motor a to drive a gear to mesh with an internal gear ring, thereby rotating the angle of the rotating arm and increasing the shooting angle of the camera.

[0010] Compared with the prior art, the present invention has the following beneficial technical effects:

[0011] When using this invention, the user fixes the position of the person to be filmed below the fixed rod. Then, depending on the specific filming situation, motor A drives the gear to mesh with the internal gear ring.

[0016] Example 1, as Figures 1-3As shown, this embodiment proposes a camera for broadcast and film shooting, including a mounting frame, a rotating arm 4, and a camera body 24. The bottom end of the mounting frame 1 has an arc-shaped groove 101, and a fixed rod 3, a support ring 2, and an internal gear ring 5 are provided at the arc-shaped groove 101. The arc-shaped groove 101 can be circular or semi-circular, with the indoor shooting center as the axis, so as to provide a better shooting angle. The rotating arm 4 is rotatably mounted on the support ring 2 and the fixed rod 3, rotating with the support ring 2 as the circumference and the fixed rod 3 as the axis. A motor a6 is provided on the rotating arm 4, and a gear 7 is provided at the output end of the motor a6. The gear 7 meshes with the internal gear ring 5. A position adjustment mechanism is also provided on the rotating arm 4. The camera body 24 is mounted on the position adjustment mechanism.

[0017] In this embodiment, the user fixes the position of the person to be photographed below the fixed rod 3. Then, depending on the specific shooting situation, the motor a6 drives the gear 7 to mesh with the internal gear ring 5. The gear 7 drives the rotating arm 4 to rotate around the fixed rod 3 as the axis until the position of the camera body 24 moves to the angle desired by the user. Then, the position adjustment mechanism is used to further adjust the position of the camera body 24 to increase the shooting angle of the camera body and improve the versatility of the camera.

[0018] Example 2, as Figures 1-3 As shown, this embodiment proposes a camera for broadcasting and filming. Compared with Embodiment 1, in this embodiment, the position adjustment mechanism includes a motor d8 mounted on a rotating arm 4, a bevel gear a9 mounted on the motor d8, a bidirectional screw 10 rotatably mounted on the rotating arm 4, a bevel gear b11 mounted on the bidirectional screw 10, two moving blocks 12 threadedly connected to each other on the bidirectional screw 10, a connecting rod 13 and an adjusting rod 14 rotatably mounted on the two moving blocks 12 respectively, a mounting plate 15 rotatably connected to the connecting rod 13, an intermediate telescopic assembly 16 rotatably connected at both ends to the mounting plate 15 and the rotating arm 4 respectively, a direction adjustment assembly mounted on the mounting plate 15, and a fixing assembly mounted on the direction adjustment assembly; the camera body 24 is mounted on the fixing assembly.

[0019] In this embodiment, the user drives the bevel gear a9 and bevel gear b11 to mesh through the motor d8, thereby driving the bidirectional screw 10 to rotate. The bidirectional screw 10 drives the two moving blocks 12 to move relative to each other or in opposite directions, thereby adjusting the distance between the camera body 24 and the ground and ensuring the shooting angle of the camera.

[0020] Example 3, as Figure 2 and Figure 3As shown, this embodiment proposes a camera for broadcasting and filming. Compared with the first embodiment, in this embodiment, the aiming component includes an aiming frame 26 mounted on the mounting plate 15, a motor b17 mounted on the aiming frame 26, a threaded rod 18 mounted on the output end of the motor b17, an aiming block 19 threadedly connected to the threaded rod 18, and a motor c25 mounted on the mounting plate 15; the aiming block 19 is rotatably connected to one end of the aiming rod 14, and the bottom end of the mounting plate 15 has a rotating groove 151, in which the fixing components are distributed.

[0021] In this embodiment, the motor b17 drives the threaded rod 18 to rotate, the threaded rod 18 drives the adjusting block 19 to adjust its position, and the adjusting block 19 drives the adjusting rod 14 to move to a position close to the motor c25, thereby changing the center of gravity of the camera body 24, so that the camera body 24 can tilt downward.

[0022] Example 4, as Figure 3 As shown, this embodiment proposes a camera for broadcasting and filming. Compared to Embodiment 1, in this embodiment, the fixing assembly includes a fixing frame 20 disposed at the output end of motor c25, multiple rotating cylinders 21 arranged circumferentially on the fixing frame 20, two fixing plates 22 disposed opposite each other at the bottom end of the fixing frame 20, one clamping plate 23 slidably disposed on each of the two fixing plates 22, and a spring disposed between the fixing plates 22 and the clamping plates 23; the multiple rotating cylinders 21 are all in rolling contact with the mounting plate 15. Multiple fixing grooves are evenly distributed on the fixing plates 22.

[0023] In this embodiment, the motor C25 drives the fixing frame 20 to rotate, and multiple rotating cylinders 21 support the fixing frame 20 by abutting against it. At the same time, the rotation of the multiple rotating cylinders 21 reduces the friction of the fixing frame 20 and improves the smoothness of rotation. When the camera body 24 is installed between the two clamping plates 23, the spring drives the clamping plates 23 to abut against the camera body 24, and the user connects the camera body 24 to the fixing slot with a bolt threaded through it. This ensures the fixing effect of the camera body 24 while increasing the contact area between the camera body 24 and the outside air, thus ensuring the heat dissipation speed of the camera body 24.

[0024] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
