Description

Technical Field

[0001] This utility model relates to the field of robotics technology, and in particular to a noise-reducing and silent studio camera robot. Background Technology

[0002] Studio camera robots are automated devices used to mount cameras and achieve multi-degree-of-freedom motion shooting. They are widely used in professional shooting scenarios such as television studios and virtual studios. These robots typically include a base, multiple robotic arms, and drive motors that drive the movements of each robotic arm. Through the coordinated movement of the joints, they achieve precise control over the camera's posture and position.

[0003] Studio environments are extremely sensitive to noise. The noise from camera robots primarily originates from the drive motors that power the robotic arms. To reduce noise, a common approach is to design all drive structures as internal components, i.e., enclosing the drive motors with complex protective housings or other enclosed structures. However, a fully internal design leads to a complex overall structure, increased material usage, and a significant increase in production costs, hindering the widespread application of the product.

[0004] Furthermore, to meet the shooting requirements of multi-camera switching and follow-up shooting, camera robots often need to move a considerable distance along a track. This long-distance translation is typically achieved using a translation drive mechanism (such as a motor with a rack and pinion structure) to drive the robot's overall movement along the track. This drive motor has high power and generates a significant amount of heat during operation, requiring a fan for forced cooling. The fan operation itself introduces a new noise source, further increasing the difficulty of noise reduction.

[0005] Therefore, how to take targeted noise reduction measures for different noise sources in different parts of the camera robot while controlling production costs, especially taking into account the differentiated noise reduction of built-in and external drive structures, as well as the noise reduction of the translation drive heat dissipation duct, to achieve overall silent operation, is a technical problem that studio camera robots urgently need to solve. Utility Model Content

[0006] The main technical problem solved by this utility model is to provide a noise-reducing and silent studio camera robot. The lowest joint drive motor adopts built-in noise reduction, while the exposed drive motors of other joints adopt external noise reduction. The heat dissipation duct of the base combined with the noise reduction structure realizes the integration of heat dissipation and noise reduction. While controlling costs, the whole machine can operate silently and meet the low noise requirements of the studio.

[0007] To solve the above-mentioned technical problems, the present invention adopts a technical solution as follows: a noise-reducing and silent studio camera robot is provided. The robot includes a base and a robot mounted on the base. The robot includes multiple robotic arms and multiple joints. A drive motor for driving the corresponding robotic arm movement is installed at the joint. The drive motor at the bottom joint is installed at a side support seat on one side above the base. The drive motor at the bottom joint is covered by a protective shell. The side of the protective shell can be fixedly connected to the side support seat and the base.

[0008] The inner wall of the protective shell is provided with a noise reduction structure;

[0009] The robot is covered with a noise-reducing suit, which, from the outside to the inside, consists of a composite coated fabric, sound-absorbing cotton, and a Kevlar lining.

[0010] The base is also provided with a duct seat, which contains multiple air ducts, and the inner wall of the air ducts is also provided with the noise reduction structure.

[0011] The noise reduction structure includes a damping sound insulation felt and a sound-absorbing cotton. The damping sound insulation felt is bonded to the inner surface of the protective shell and the air duct, and the sound-absorbing cotton is bonded to the surface of the damping sound insulation felt.

[0012] Furthermore, the damping sound insulation felt comprises, in sequence, an aluminum foil substrate, a composite damping material layer, and an adhesive backing layer, wherein the adhesive backing layer is bonded to the inner wall of the protective shell and the air duct; the thickness of the aluminum foil substrate is 90-110 micrometers.

[0013] Furthermore, the protective shell and the air duct seat are sheet metal parts.

[0014] Furthermore, the connection between the side of the protective shell and the side support and base is sealed with adhesive. Furthermore, the sound-absorbing cotton of the noise-reducing suit has a sound absorption coefficient of 0.85.

[0015] Furthermore, the noise-reducing suit is fixed to the robotic arm via a tape or Velcro.

[0016] Furthermore, the sound-absorbing cotton in the noise reduction structure is an I-shaped sound-absorbing cotton, which has its own adhesive backing and is bonded to the surface of the damping sound insulation felt through the adhesive backing.

[0017] Furthermore, the robot is a robot capable of moving along the underlying track, and is driven to move along the track by a translation drive mechanism; the drive motor of the translation drive mechanism is installed inside the base, and the cooling fan is also installed inside the base;

[0018] The air duct is located on the side where the fan is located, and the air outlet of the air duct base is connected to the outside. The heat brought by the fan is dissipated into the environment through the air duct.

[0019] Furthermore, the lower end of the noise-reducing suit is fixed to the upper part of the protective shell, and the upper end is fixed to the end of the uppermost robotic arm.

[0020] To elaborate further, the cable box and the upper part of the cable on the robotic arm are all covered inside the noise-canceling suit, while the lower part of the cable is exposed through openings on the side of the suit.

[0021] The beneficial effects of this utility model are:

[0022] I. Differentiated Noise Reduction, Balancing Cost and Effectiveness. Different noise reduction strategies are employed based on the location and enclosure level of the noise source: For the drive motor at the lowest joint, it is mounted on the side support and covered by a protective shell, with a noise-reducing structure on the inner wall of the shell for built-in noise reduction; for the drive motors exposed at other joints, external noise reduction is achieved by covering them with noise-reducing covers. This differentiated design avoids the high costs associated with a fully built-in solution, effectively controlling production costs while meeting the studio's quiet requirements.

[0023] II. Integrated Noise Reduction and Heat Dissipation in the Base. The base incorporates an air duct seat with a noise-reducing structure on the inner wall. Heat generated by the fan driving the motor is dissipated to the external environment through the air duct. This air duct structure ensures efficient heat dissipation while effectively absorbing fan noise using damping sound-absorbing felt and sound-absorbing cotton on the inner wall, thus solving the noise reduction problem of high-power cooling fans.

[0024] III. The noise-reducing suit features a multi-layered composite structure for excellent noise reduction. From the outside in, the suit consists of a composite coated fabric, sound-absorbing cotton, and a Kevlar lining. The composite coated fabric provides outer protection and sound absorption, the sound-absorbing cotton (with a sound absorption coefficient of up to 0.85) efficiently absorbs noise, and the Kevlar lining is wear-resistant and durable. This multi-layered composite structure achieves comprehensive noise reduction by completely enveloping the robot in external noise.

[0025] IV. The noise reduction structure is a double-layer structure. Both the protective shell and the inner wall of the air duct adopt a double-layer noise reduction structure of damping sound insulation felt and sound-absorbing cotton. The damping sound insulation felt is bonded to the metal wall surface through an adhesive backing layer, the composite damping material layer attenuates vibration energy, and the aluminum foil substrate reflects sound waves; the sound-absorbing cotton (I-shaped, with self-adhesive backing) further absorbs residual noise. The double-layer structure works synergistically, and the noise reduction effect is significant.

[0037] The following specific embodiments illustrate the detailed implementation of this utility model. Those skilled in the art can easily understand the advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented in other different ways, that is, different modifications and changes can be made without departing from the scope disclosed in this utility model.

[0038] The descriptions of positions such as up, down, left, and right in this embodiment are based on the orientation in the accompanying drawings, have no special meaning, and are not intended to limit the scope of protection of this utility model.

[0039] Example: A noise-reducing, silent studio camera robot, such as... Figures 1 to 6 As shown, the robot includes a base 1 and a robot mounted on the base. The robot includes multiple robotic arms 2 and multiple joints 3. Drive motors 4 for driving the corresponding robotic arm movements are mounted at the joints. The drive motor for the lowest joint is mounted above the base 1. A side support 5 is provided on one side of the upper part of the base, and the drive motor for the lowest joint is mounted on the side support 5. Figure 2 As shown, the drive motor at the bottom joint is covered by the protective shell 6, and the side of the protective shell can be fixedly connected to the side support and the base.

[0040] The inner wall of the protective shell is provided with a noise reduction structure;

[0041] like Figure 5 The robot is covered with a noise-reducing suit 10, which consists of a composite coated fabric, sound-absorbing cotton, and Kevlar lining fabric from the outside to the inside.

[0042] like Figure 3 and Figure 4 As shown, the base 1 is also provided with a duct seat 7, and the duct seat is provided with a plurality of ducts 71. The inner wall of the duct is also provided with the noise reduction structure.

[0043] like Figure 6 As shown, the noise reduction structure includes a damping sound insulation felt 11 and a sound-absorbing cotton 12. The damping sound insulation felt is bonded to the inner surface of the protective shell 6 and the air duct 71, and the sound-absorbing cotton is bonded to the surface of the damping sound insulation felt.

[0044] In this embodiment, the damping sound insulation felt sequentially comprises an aluminum foil substrate, a composite damping material layer, and an adhesive backing layer. The adhesive backing layer is bonded to the inner wall of the protective shell and the air duct. The thickness of the aluminum foil substrate is 90-110 micrometers. The composite damping material layer is a roll or sheet-type sound insulation material with EPDM rubber as the main component. This material is existing technology and will not be described in detail.

[0045] In this embodiment, the protective shell 6 and the air duct seat 7 are sheet metal parts.

[0046] In this embodiment, the connection between the side of the protective shell 6 and the side support and base is sealed with adhesive. The adhesive can be glass glue, but is not limited to any type; anything that serves a connecting and sealing function is acceptable. Compared to bolt fastening, sealing and noise reduction are more effective.

[0047] In this embodiment, the sound absorption coefficient (NRC) of the sound-absorbing cotton in the noise-reducing suit 10 is 0.85. This parameter is limited to ensure a relatively ideal noise reduction effect.

[0048] In this embodiment, the noise-reducing suit 10 is fixed to the robotic arm 2 by a strap or Velcro. Other fixing methods, such as zippers, can also be used.

[0049] In this embodiment, the sound-absorbing cotton in the noise reduction structure is an I-shaped sound-absorbing cotton. This I-shaped sound-absorbing cotton has self-adhesive backing and is bonded to the surface of the damping sound insulation felt through the adhesive backing. This I-shaped sound-absorbing cotton can be polyurethane foam, but is not limited to this.

[0050] In this embodiment, the robot is a robot capable of moving along the underlying track 8, and is driven to move along the track by a translation drive mechanism 9; the drive motor of the translation drive mechanism is installed inside the base, and the cooling fan is also installed inside the base;

[0051] The air duct 71 is located on the side near the fan. The air outlet of the air duct base 7 is connected to the outside. For example, the air outlet can be set on the shell of the base. The heat brought by the fan is dissipated into the environment through the air duct. Long-distance translation is usually achieved by using a translation drive mechanism (such as a motor with a gear and rack structure) to drive the robot to move along the track. This part is not within the protection scope of this utility model, so it will not be described in detail.

[0052] In this embodiment, the lower end of the noise-reducing suit 10 is fixed to the upper part of the protective shell 6, and the upper end is fixed to the end of the uppermost robotic arm 2.

[0053] In this embodiment, the cable box and the upper part of the cable on the robotic arm 2 are covered inside the noise-reducing suit, and the lower part of the cable is exposed through the opening on the side of the noise-reducing suit.

[0054] In this embodiment, although the noise-reducing suit, protective shell, and air duct base are shown in different figures, in actual applications, the above structures can be integrated into one robot or used selectively as needed.

[0055] The working process of this noise-reducing and silent studio camera robot is as follows:

[0056] Camera posture adjustment: The robot drives the corresponding robotic arm movements through the drive motors at each joint to achieve multi-degree-of-freedom posture adjustment. The camera installed at the end of the uppermost robotic arm can then complete multi-angle and multi-directional shooting.

[0057] Translational motion: The translational drive mechanism inside the base drives the entire robot to translate along the track, enabling long-distance camera position changes and meeting the needs of multi-camera shooting.

[0058] Noise generation and noise reduction process:

[0059] The noise generated by the drive motor during operation is handled through two noise reduction paths:

[0060] (1) Noise reduction of the drive motor at the bottom joint: The motor is installed on the side support above the base and is covered by a sheet metal protective shell. The side of the protective shell is sealed to the side support and the base with glue to form a closed space. The inner wall of the protective shell is bonded with damping sound insulation felt (aluminum foil substrate + composite damping material layer + adhesive backing layer), and I-shaped sound-absorbing cotton is then bonded to the surface of the damping sound insulation felt. The noise in the closed space is attenuated by the damping sound insulation felt, the aluminum foil layer reflects the sound waves, and the sound-absorbing cotton absorbs the residual noise. After multiple layers of action, the noise transmitted to the outside is greatly reduced.

[0061] (2) Noise reduction for other joint drive motors: The exposed drive motors and robotic arms are completely covered by a noise-reducing suit. The noise-reducing suit consists of a composite coated fabric, sound-absorbing cotton, and Kevlar lining from the outside to the inside. Noise passes through the Kevlar lining and is efficiently absorbed by the sound-absorbing cotton (sound absorption coefficient 0.85), and is further blocked by the composite coated fabric. The lower end of the noise-reducing suit is fixed to the upper part of the protective shell, and the upper end is fixed to the end of the uppermost robotic arm. It is fixed to the connection points of each robotic arm by tape or Velcro, completely covering the cable box and the upper cable. Only a hole is opened on the lower side to lead out part of the cable, achieving overall covering noise reduction.

[0062] (3) Noise reduction of the heat dissipation duct of the base: The translation drive motor generates a lot of heat when it runs. When the fan runs to perform forced heat dissipation, it blows the heat and noise into multiple ducts in the duct seat. The inner wall of the duct is also equipped with a noise reduction structure of damping sound insulation felt and sound-absorbing cotton. When the airflow flows through the duct, it carries the heat to the air outlet connected to the outside and discharges it. At the same time, the noise is attenuated and absorbed by the damping sound insulation felt and sound-absorbing cotton in the duct, realizing the simultaneous treatment of heat dissipation and noise reduction.

[0063] By combining the above-mentioned three methods of built-in noise reduction (protective shell), external noise reduction (noise reduction suit), and air duct noise reduction, this utility model achieves silent operation of the whole machine while controlling costs, meeting the low noise requirements of the studio for the camera robot.

[0064] The above description is merely an embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structure made using the contents of the present utility model specification and drawings, or directly or indirectly applied to other related technical fields, are similarly included within the patent protection scope of the present utility model.
