Description

Technical Field

[0001] This utility model relates to the field of electronic equipment technology, and in particular to a camera bracket and a recording and broadcasting device using the camera bracket. Background Technology

[0002] Recording and broadcasting equipment is widely used in work meetings, teaching, and other scenarios. It can integrate video, audio, and image files captured on-site to generate standardized media files, which can then be used for live streaming, storage, post-editing, and on-demand playback.

[0003] Existing recording equipment mainly consists of a jib arm and a bracket for mounting the camera. The camera's shooting angle is adjusted by adjusting the jib arm. However, in order to achieve a sufficiently high degree of freedom, the jib arm has many joints, but each joint has a certain gap. When multiple joints are connected in series, these gaps accumulate, causing the camera mounted on the bracket at the end of the jib arm to shift significantly, resulting in a skewed shooting image. Utility Model Content

[0004] This application provides a camera bracket and recording equipment that achieves the horizontal requirements during camera shooting with a simple structure.

[0005] In a first aspect, embodiments of this application provide a camera bracket, including a rocker arm and a mounting bracket. The mounting bracket includes a first annular body, a second annular body, and a mating member. The first annular body and the second annular body are sleeved together, and the mating member is supported between the first annular body and the second annular body and configured to allow the first annular body and the second annular body to rotate relative to each other.

[0006] The first annular body is connected to the rocker arm. The second annular body includes an annular base and a mounting part connected to the annular base. The annular base is sleeved with the first annular body. The mounting part is used to mount the camera. In the height direction of the mounting bracket, the center of gravity of the second annular body is configured to be located at the lower part of the annular base, so that the second annular body can adjust the camera mounted on the mounting part horizontally under the drive of gravity.

[0007] Based on the camera bracket of this application embodiment, the camera can automatically adjust its posture under the action of gravity, so that the camera can automatically maintain a horizontal state after installation, simplifying the installation and calibration process.

[0008] In some embodiments, an mounting cavity is provided in the annular base, and a counterweight is provided in the mounting cavity in the second annular body. The top of the counterweight has a support surface, and the counterweight is formed as a mounting part.

[0009] In its natural state, the supporting surface is lower than the center of the annular base.

[0010] In this implementation, by increasing the gravity, i.e. the weight of the counterweight, the torque can be increased, thereby enhancing the ability of the second ring body to resist the rotational torque relative to the first ring body. The second ring body is less likely to rotate, thus ensuring the stability of the camera and making the camera closer to an absolutely horizontal state.

[0011] In some embodiments, the support surface is a plane.

[0012] In some embodiments, the fasteners are also included to fix the first annular body and the second annular body relative to each other in the circumferential direction, and to release the connection between the first annular body and the second annular body so that they can rotate relative to each other in the circumferential direction.

[0013] In some embodiments, one of the first annular body and the second annular body is provided with a fixing hole, and a fastener passes through the fixing hole and abuts against the other of the first annular body and the second annular body to fix the first annular body and the second annular body relative to each other in the circumferential direction.

[0014] In this implementation, the first and second annular bodies can be adjusted to rotate or be fixed relative to each other using fasteners, so that the mounting bracket can adapt to a variety of different installation scenarios and requirements.

[0015] In some embodiments, the fixing hole is a threaded hole, and the fastener is provided with external threads.

[0016] In this implementation, during installation, simply screw the fastener into the threaded hole and let it abut against the outer wall of the second annular body to achieve fixation. During disassembly, simply rotate the fastener in the opposite direction to easily remove it.

[0017] In some embodiments, two mating parts are provided and are spaced apart axially from the first annular body and the second annular body, forming a clearance cavity between the two mating parts, and fasteners are inserted into the clearance cavity.

[0018] In this implementation, the fastener can achieve circumferential relative fixation of the two first annular bodies and the second annular body without affecting the mating parts, and the two mating parts can improve the rotational stability between the first annular body and the second annular body.

[0019] In some embodiments, the first annular body is sleeved on the outside of the second annular body, the outer wall of the first annular body is provided with a clearance hole that penetrates through in the thickness direction, and the second annular body is provided with a mounting hole that penetrates through its outer wall and the mounting part.

[0020] The camera bracket also includes a locking device with a clearance hole that extends into the mounting hole and into the interior of the second annular body to fix the camera relative to the mounting part.

[0021] In this implementation, during installation, the mounting hole and the clearance hole are aligned. The locking fastener passes through the clearance hole and extends into the mounting hole, thus penetrating the interior of the second annular body. The locking fastener secures the camera to the mounting portion of the second annular body.

[0022] In some embodiments, the mating component is a bearing.

[0023] In some embodiments, the rocker arm includes a first cantilever, one end of which is rotatably connected to a first annular body.

[0024] In some embodiments, the first cantilever includes a first connecting rod and a second connecting rod, one end of the first connecting rod being rotatably connected to a first annular body, and the end of the first connecting rod away from the first annular body being rotatably connected to the second connecting rod.

[0025] The first connecting rod is defined to have a first rotation axis O that rotates with the first annular body, and the first connecting rod is defined to have a second rotation axis P that rotates with the second connecting rod. The plane perpendicular to the first rotation axis O and the plane perpendicular to the second rotation axis P are arranged perpendicularly to each other.

[0026] In this implementation, the camera's left-right direction, up-down direction, and tilt angle can be adjusted in pairs. Furthermore, the first and second annular bodies can automatically adjust the camera's horizontal direction, enabling multi-angle adjustment of the camera.

[0027] In some embodiments, the first annular body is provided with a handle for the user to hold, and the handle is connected to the end face of the first annular body opposite to the connection with the rocker arm.

[0028] Based on the camera bracket of this application embodiment, the mating parts enable smooth rotation between the first and second annular bodies, while reducing friction and resistance during rotation. Since the second annular body includes an annular base and a mounting portion connected to the annular base, the center of gravity of the second annular body is located at the lower part of the annular base. After the camera is mounted on the mounting portion, the overall center of gravity of the camera and the second annular body remains at the lower part of the second annular body. Thus, the camera can automatically adjust its posture under the influence of gravity, ensuring it remains horizontal after installation. This simplifies the installation and calibration process, eliminating the need for tedious manual adjustments by the photographer to ensure the horizontality of the captured image. This not only improves shooting efficiency but also reduces image tilting caused by improper human operation, further enhancing shooting quality. Furthermore, the solution of this application utilizes gravity to achieve automatic horizontal adjustment of the camera without requiring other power devices, resulting in a simple overall structure and lower cost.

[0029] Secondly, embodiments of this application provide a recording and broadcasting device, including:

[0030] Mobile base;

[0031] As described above, the camera bracket is mounted on the movable base. Attached Figure Description

[0041] To make the objectives, technical solutions and advantages of this utility model clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0044] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0045] Existing recording equipment mainly consists of a jib arm and a bracket for mounting the camera. The camera's shooting angle is adjusted by adjusting the jib arm. However, in order to achieve a sufficiently high degree of freedom, the jib arm is equipped with many joints. But each joint has a certain gap. When multiple joints are connected in series, these gaps accumulate, causing the camera mounted on the bracket at the end of the jib arm to shift significantly, resulting in a skewed shooting image.

[0046] Please see Figure 1 This application provides a camera bracket 1, including a rocker arm 10 and a mounting bracket 20. The mounting bracket 20 is connected to one end of the rocker arm 10 and is used to mount a camera 50. The rocker arm 10 includes multiple cantilevers that can extend, rotate, and tilt to allow the photographer to adjust the angle and position of the camera 50 as needed. These cantilevers can be made of high-strength materials, such as metal, carbon fiber, rigid plastic, etc., to ensure their robustness, durability, and ability to support the weight of the camera 50.

[0047] Please see Figure 2The mounting bracket 20 includes a first annular body 210, a second annular body 220, and a mating member 230. The first annular body 210 and the second annular body 220 are sleeved together, and the mating member 230 is supported between the first annular body 210 and the second annular body 220 and configured to allow the first annular body 210 and the second annular body 220 to rotate relative to each other. The first annular body 210 is connected to the rocker arm 10. The second annular body 220 includes an annular base 221 and a mounting portion 222 connected to the annular base 221. The annular base 221 is sleeved with the first annular body 210. The mounting portion 222 is used to mount the camera 50. In the height direction of the mounting bracket 20, the center of gravity of the second annular body 220 is configured to be located at the lower part of the annular base 221, so that the second annular body 220 can adjust the camera 50 mounted on the mounting portion 222 horizontally under the drive of gravity.

[0048] In this application, the mating part 230 allows for smooth rotation between the first annular body 210 and the second annular body 220, while reducing friction and resistance during rotation. Since the second annular body 220 includes an annular base 221 and a mounting portion 222 connected to the annular base 221, the center of gravity of the side of the annular base 221 where the mounting portion 222 is located will be at the lower part of the second annular body 220. Even after the camera 50 is mounted on the mounting portion 222, the overall center of gravity of the camera 50 and the second annular body 220 will still be located at the lower part of the second annular body 220. Please refer to the relevant documentation. Figure 4 and Figure 5 Thus, the camera 50 of this application can automatically adjust its posture under the action of gravity, so that the camera 50 can automatically maintain a horizontal state after installation, simplifying the installation and calibration process. Photographers no longer need to make tedious manual adjustments to ensure the horizontality of the shooting image. This not only improves shooting efficiency, but also reduces the problem of image tilt caused by improper human operation, further improving the shooting quality.

[0049] Furthermore, the connection between the first annular body 210 and the second annular body 220 can be either the first annular body 210 being fitted onto the outside of the second annular body 220, or the second annular body 220 being fitted onto the outside of the first annular body 210. Specifically, in the embodiment where the first annular body 210 is fitted onto the outside of the second annular body 220, the rocker arm 10 can be connected to the outer wall of the first annular body 210, and the camera 50 can be installed inside the second annular body 220. In the embodiment where the second annular body 220 is fitted onto the outside of the first annular body 210, the first annular body 210 can extend a mounting portion on one side to connect with the rocker arm 10, and the second annular body 220 can extend a mounting structure for mounting the camera 50 on the side opposite to the mounting portion, the mounting structure being provided with a mounting portion 222. Here, this application does not impose specific limitations on the connection method between the first annular body 210 and the second annular body 220.

[0050] For further details, please refer to Figure 2 and Figure 3 A counterweight 223 can be provided on the second annular body 220 to ensure that, after the camera 50 is installed, the overall center of gravity of the camera 50 and the second annular body 220 is located at the lower part of the annular base 221. It is understood that torque is the product of force and lever arm. With a fixed lever arm (i.e., the vertical distance from the center of gravity to the axis of rotation), the torque can be increased by increasing the gravity (i.e., the weight of the counterweight 223). Thus, when the second annular body 220 rotates relative to the first annular body 210 to its lowest center of gravity position, the center of gravity of the second annular body 220 is at its lowest, and its ability to resist external interference is strongest. The enhanced ability of the second annular body 220 to resist the rotational torque relative to the first annular body 210 means that under the same external force, the second annular body 220 is less likely to rotate, thereby ensuring the stability of the camera 50 and making the camera 50 closer to an absolutely horizontal state. It is understood that, in embodiments where the second annular body 220 is fitted onto the outside of the first annular body 210, the counterweight 223 can be provided at the bottom of the aforementioned mounting structure.

[0051] Please see Figure 3 In some embodiments, a mounting cavity 220a is formed within the annular base 221. The presence of the mounting cavity 220a allows the counterweight 223 to be housed within the second annular body 220, thereby maintaining the overall aesthetics and compactness of the mounting bracket 20. Furthermore, the mounting cavity 220a also protects the camera 50, preventing it from being struck by external objects during shooting and reducing the likelihood of damage. In this application, the counterweight 223 is formed as the aforementioned mounting portion 222. The top of the counterweight 223 has a support surface 224, which is used to mount the camera 50, thus improving the stability of the camera 50 mounted within the second annular body 220. In its natural state, the support surface 224 is lower than the center of the second annular body 220 and the first annular body 210, ensuring that the camera 50 mounted on the support surface 224 automatically maintains a horizontal position under the influence of gravity.

[0052] The counterweight 223 is formed as the mounting part 222 described above. The counterweight 223 and the annular base 221 can be an integral structure, for example, they can be integrally molded. This makes the manufacturing of the entire second annular body 220 easier, and the structure is more stable and the cost is lower.

[0053] In other embodiments, the mounting portion 222 can take various forms. The mounting portion 222 can be a separate boss structure from the annular base 221, and the boss structure can have one or more slots. The camera 50 or its bracket has matching pins. After the pins are inserted into the slots, the camera 50 is fixed to the mounting portion 222 by a locking mechanism (such as screws, clips, etc.). The mounting portion 222 can also include magnetic material components, with the bottom of the camera 50 or its bracket having a magnetic or magnetically attractable material. The camera 50 is magnetically attracted to the mounting portion 222, enabling quick installation and removal. The mounting portion 222 can be a snap-fit ​​structure on the annular base 221, with matching slots on the camera 50 or its bracket. The camera 50 or its bracket is secured by aligning its slots with the snap-fit. The mounting portion 222 can also be formed as a small bracket with a mounting platform or clamp for placing or holding the camera 50. The camera 50 is fixed by being placed on a platform or clipped in a clamp.

[0054] Optionally, in the embodiment where the counterweight 223 is formed as the mounting part 222 described above, the support surface 224 is a plane, which facilitates the mounting of the camera 50. Of course, in other embodiments, the support surface 224 can be an arc surface or a curved surface, as long as the camera 50 is fixed.

[0055] It should be noted that the axial dimensions of the first annular body 210 and the second annular body 220 can be smaller than the axial dimension of the camera 50. This allows the camera 50 to be partially protruding when mounted in the mounting cavity 220a, making it easier for the photographer to grip and operate the camera 50. In this case, the overall size of the mounting bracket 20 is smaller, resulting in lower manufacturing costs. Alternatively, for better protection of the camera 50, the axial dimensions of the first annular body 210 and the second annular body 220 can be larger than the axial dimension of the camera 50. This allows the camera 50 to be completely housed within the mounting cavity 220a without protruding beyond the second annular body 220, providing better protection and reducing the risk of damage from external collisions or friction. In this configuration, the lens of the camera 50 can be flush with one end face of the second annular body 220 to ensure the required camera angle while minimizing obstruction by the second annular body 220.

[0056] In one embodiment, a fastener 30 is further included. The fastener 30 is used to connect the first annular body 210 and the second annular body 220 so that they are relatively fixed in the circumferential direction, and to release the connection between the first annular body 210 and the second annular body 220 so that they can rotate relative to each other in the circumferential direction. The fastener 30 can be in the form of a clamp, comprising a clamp body and a bolt. The clamp body can be a semi-circular or U-shaped metal or high-strength plastic component used to surround and fit against the outer periphery of the first annular body 210 and the second annular body 220. The inner side of the clamp body may be provided with anti-slip or interlocking parts to increase the friction with the surfaces of the first annular body 210 and the second annular body 220 and prevent slippage. The bolt has a threaded portion for passing through a hole in the clamp body and engaging with a nut. By tightening the nut, the bolt presses one end of the clamp body tightly against one surface of the first annular body 210 or the second annular body 220, while the other end of the clamp body naturally fits against the surface of the other annular body, thereby achieving relative fixation in the circumferential direction.

[0057] Please see Figure 3 In some embodiments, one of the first annular body 210 and the second annular body 220 is provided with a fixing hole 210a. The fastener 30 passes through the fixing hole 210a and abuts against the other of the first annular body 210 and the second annular body 220. Specifically, in the portion where the first annular body 210 and the second annular body 220 are fitted together, one of the first annular body 210 and the other is located on the outside and the other is located on the inside. When the annular body located on the outside is provided with a fixing hole 210a, the fastener 30 passes through the fixing hole 210a from the outside of the annular body and is fixed relative to the annular body. Then, the fastener 30 abuts against the outer wall surface of the other annular body. When the annular body located on the inside is provided with a fixing hole 210a, the fastener 30 passes through the fixing hole 210a from the inside of the annular body and is fixed relative to the annular body. Then, the fastener 30 abuts against the inner wall surface of the other annular body, thereby fixing the first annular body 210 and the second annular body 220 relative to each other in the circumferential direction. For example, the first annular body 210 is provided with a fixing hole 210a.

[0058] Optionally, the fixing hole 210a is a threaded hole, and the fastener 30 is provided with external threads. The first annular body 210 is sleeved on the outside of the second annular body 220, and the first annular body 210 is provided with a threaded hole. The fastener 30 and the first annular body 210 are fixed relative to each other through threaded engagement. The fastener 30 can be in the form of a screw, bolt, etc. During installation, simply screw the fastener 30 into the threaded hole and let it abut against the outer wall surface of the second annular body 220 to achieve fixation. During disassembly, simply rotate the fastener 30 in the opposite direction to easily remove it. Of course, the fastener 30 and the first annular body 210 can also be connected by a snap-fit ​​or other means.

[0059] The fastener 30 allows for relative rotation or fixation of the first annular body 210 and the second annular body 220, enabling the mounting bracket 20 to adapt to various installation scenarios and requirements. For example, in scenarios requiring a fixed shooting angle, the fastener 30 can be used to fix the first annular body 210 and the second annular body 220 relative to each other; when mounting the camera 50 in the second annular body 220, the fastener 30 can be used to fix the first annular body 210 and the second annular body 220 relative to each other; while in scenarios where the camera 50 needs to automatically adjust its posture, the fastener 30 can be loosened, allowing the first annular body 210 and the second annular body 220 to rotate relative to each other.

[0060] Furthermore, the fastener 30 can be provided in two parts, and the fixing holes 210a are also provided in two parts. The two fixing holes 210a are located on opposite sides of the connection between the first annular body 210 and the rocker arm 10, which can improve the stability of the fastener 30 in fixing the first annular body 210 and the second annular body 220.

[0061] In some embodiments, two mating members 230 are provided, spaced apart axially from the first annular body 210 and the second annular body 220, forming a clearance cavity 20a between the two mating members 230, and the fastener 30 passes through the clearance cavity 20a. In this way, the fastener 30 can achieve circumferential relative fixation of the two annular bodies without affecting the mating members 230. Furthermore, the two mating members 230 can improve the rotational stability between the first annular body 210 and the second annular body 220.

[0062] Please see Figure 2 and Figure 3 In some embodiments, the first annular body 210 is sleeved on the outside of the second annular body 220. The outer wall surface of the first annular body 210 is provided with a clearance hole 210b that penetrates in the thickness direction. The second annular body 220 is provided with a mounting hole 220b that penetrates its outer wall surface and the mounting portion 222. The camera bracket 1 also includes a locking fastener 40, which passes through the clearance hole 210b and extends into the mounting hole 220b and into the interior of the second annular body 220 to fix the camera 50 relative to the mounting portion 222. Understandably, during installation, the mounting hole 220b and the clearance hole 210b are aligned, and the locking fastener 40 passes through the clearance hole 210b and extends into the mounting hole 220b and into the interior of the second annular body 220. The locking fastener 40 fixes the camera 50 relative to the mounting portion 222 of the second annular body 220.

[0063] Please see Figure 3Optionally, the bottom of the camera 50 is provided with a threaded hole, and the locking fastener 40 can be in the form of a screw, bolt, etc. The locking fastener 40 is fixedly connected to the threaded hole. After being fixed in place, the head of the locking fastener 40 abuts against the outer wall surface of the second annular body 220. In this way, the locking fastener 40 can fix the camera 50 in both the circumferential and axial directions. Furthermore, the mounting hole 220b can be in the form of a threaded hole to improve the stability of the relative fixation between the locking fastener 40 and the second annular body 220, and prevent the camera 50 from loosening or shifting due to vibration or external force during shooting.

[0064] Based on the above, the mating component 230 is a bearing, including but not limited to rolling bearings and sliding bearings. Rolling bearings utilize rolling elements (such as balls or rollers) rolling between the inner and outer rings to reduce friction. Sliding bearings utilize sliding friction to support rotating components. This application does not limit the specific form of the mating component 230. Specifically, when the mating component 230 is a rolling bearing, the outer ring of the rolling bearing is interference-fitted with the inner wall of the first annular body 210, and the inner ring of the rolling bearing is interference-fitted with the outer wall of the second annular body 220. Of course, in other embodiments, the mating component 230 may only include the aforementioned rolling elements, with the first annular body 210 and the second annular body 220 forming part of the bearing, and the rolling elements fixed between the first annular body 210 and the second annular body 220.

[0065] Please see Figure 2 and Figure 3 In some embodiments, the rocker arm 10 includes a first cantilever 110, one end of which is rotatably connected to a first annular body 210. This facilitates adjustment of the position or angle of the mounting bracket 20, thereby adjusting the shooting angle of the camera 50. The first cantilever 110 includes a first connecting rod 111 and a second connecting rod 112. One end of the first connecting rod 111 is rotatably connected to the first annular body 210, and the end of the first connecting rod 111 away from the first annular body 210 is rotatably connected to the second connecting rod 112. The first connecting rod 111 is defined to have a first rotation axis O that rotates with the first annular body 210, and the first connecting rod 111 is defined to have a second rotation axis P that rotates with the second connecting rod 112. The plane perpendicular to the first rotation axis O and the plane perpendicular to the second rotation axis P are arranged perpendicularly to each other.

[0066] Please see Figure 3Specifically, the first connecting rod 111 and the second connecting rod 112 extend in the same direction, i.e., remain in a straight line. One end of the first connecting rod 111 is rotatably connected to the first annular body 210, and the other end is rotatably connected to the second connecting rod 112; the rotation directions of the first connecting rod 111 and the objects connected to the two ends are not the same, and the plane perpendicular to the first rotation axis O and the plane perpendicular to the second rotation axis P are mutually perpendicular. That is to say, the first rotation axis O and the second rotation axis P can be any combination of the X-axis, Y-axis, and Z-axis. Among them, the X-axis, Y-axis, and Z-axis correspond to the width direction, height direction, and axial direction of the mounting bracket 20, respectively. In this way, the camera 50 can be adjusted in any combination of left-right, up-down, and tilt angles. Moreover, the first annular body 210 and the second annular body 220 can automatically adjust the horizontal direction of the camera 50, and this application can realize multi-angle adjustment of the camera 50.

[0067] Furthermore, the rocker arm 10 also includes a second cantilever 120 and a third cantilever 130. The opposite sides of the second cantilever 120 rotate relative to the first cantilever 110 and the third cantilever 130, respectively.
