Technical Field
[0001] This utility model belongs to the technical field of interview equipment, specifically relating to a multimodal interview auxiliary device. Background Technology
[0002] As multimodal content acquisition methods become increasingly popular in news interviews, self-media recording, and online live streaming, multimodal interview auxiliary devices that integrate interview cameras, microphones, and interactive displays are becoming common equipment. These devices typically feature real-time framing, voice capture, and basic operation controls. They are portable thanks to their compact support components and can be used directly on desktops and other surfaces to improve interview efficiency and content acquisition quality. However, existing multimodal interviewing aids mostly rely on three short, tilted supports arranged in a triangular pattern for tabletop placement. Their footprint is limited by the tabletop or flat platform, and the placement height is relatively low. This makes the device prone to shaking or shifting during actual interviews due to tabletop vibration, external force contact, or changes in height adjustment, which in turn affects the stability of the video footage and the microphone's sound pickup effect. Utility Model Content
[0003] The purpose of this utility model is to provide a multimodal interview assistance device to solve the problem mentioned in the background art that the existing multimodal interview assistance devices usually rely on short inclined brackets arranged in a triangle for desktop placement. Due to the limitation of bracket length and desktop area, the placement point is too low. The device is prone to shaking and displacement when the desktop vibrates, is touched by external force, or the height is adjusted, which in turn affects the stability of the camera and the quality of microphone pickup.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a multimodal interview auxiliary device, comprising a cylindrical support and a lifting and stabilizing sleeve sleeved on its exterior, wherein the bottom end of the lifting and stabilizing sleeve has an integrated support sleeve, and its circular outer wall has three inclined mounting brackets equidistantly spaced for mounting the multimodal interview auxiliary device, an interview host is provided above the cylindrical support, and a follow-up counterweight stabilizing device is provided inside the cylindrical support and at its bottom end, wherein the follow-up counterweight stabilizing device comprises a disc-shaped solid metal plate, a follow-up cylindrical rod and a follow-up movable hole, the follow-up movable hole opening downwards inside the cylindrical support, and the top end of the follow-up cylindrical rod is inserted into the follow-up movable hole and can move up and down, and the bottom end of the follow-up cylindrical rod is provided with a disc-shaped solid metal plate, which is located between the triangularly arranged inclined mounting brackets.
[0005] Preferably, the follow-up counterweight stabilizing device further includes a fixed threaded head and a fixed threaded hole. The fixed threaded head is welded to the bottom end of the follow-up cylindrical rod, and the fixed threaded hole is opened in the center of the disc-shaped solid metal plate. The disc-shaped solid metal plate is screwed onto the outside of the fixed threaded head through the fixed threaded hole.
[0006] Preferably, the follow-up counterweight stabilizing device further includes a magnetic knob, a magnetic anti-detachment sleeve, and an anti-detachment sleeve. The magnetic knob and the anti-detachment sleeve are respectively sleeved and fixed to the outside of the bottom end and the outside of the top end of the follow-up cylindrical rod. The anti-detachment sleeve is inserted into the follow-up movable hole, and the magnetic anti-detachment sleeve is fixed inside the bottom opening of the follow-up movable hole. It is also sleeved on the outside of the follow-up cylindrical rod.
[0007] Preferably, the disc-shaped solid metal plate is placed on the table along with three inclined mounting brackets by its own weight. When the cylindrical bracket is raised, its internal follow-up movable hole moves upward outside the follow-up cylindrical rod and the anti-detachment sleeve to ensure that the disc-shaped solid metal plate is always placed close to the table and that the anti-detachment sleeve is blocked at the top of the magnetic anti-detachment sleeve.
[0008] Preferably, after the disc-shaped solid metal plate is removed, the follower cylindrical rod is pushed upwards, causing the magnetic knob to adhere to and magnetically attach to the magnetic anti-detachment sleeve and the bottom of the cylindrical bracket, so that the follower cylindrical rod located at the top of the magnetic knob can be stored in the follower movable hole.
[0009] Preferably, the inner corner angle between the inclined mounting bracket and the cylindrical bracket is 30 degrees, and the three inclined mounting brackets are arranged in an equilateral triangle angle, with a ball head at the bottom, and the diameter of the inclined mounting bracket is half the diameter of the ball head.
[0010] Preferably, the lifting and stabilizing sleeve has an inherent internally threaded cylinder near the top right end, and a hand-tightened height-fixing screw is inserted inside the internally threaded cylinder. When the hand-tightened height-fixing screw is tightened, its screw rod can press tightly against the outer wall of the cylindrical bracket to prevent the cylindrical bracket from moving up and down in the lifting and stabilizing sleeve. When the hand-tightened height-fixing screw is loosened and unlocked, the cylindrical bracket can move up and down in the lifting and stabilizing sleeve to change the overall height of the multimodal interviewing auxiliary device.
[0011] Preferably, the bottom center of the interview host is fixed with a rotating connecting block by a screw fixing piece, the top of the cylindrical bracket has a U-shaped corner sleeve, and the rotating connecting block is inserted into the U-shaped corner sleeve.

[0014] Compared with the prior art, this utility model provides a multimodal interview assistance device, which has the following beneficial effects: This invention features a novel follow-up counterweight stabilization device installed inside and at the bottom of a cylindrical bracket. This allows the multimodal interview auxiliary device to maintain reliable stability at different usage heights. After the multimodal interview auxiliary device is supported on the table by three tilting brackets, the disc-shaped solid metal plate in the follow-up counterweight stabilization device will naturally adhere to the table. Its own weight forms an effective downward pressure, which can significantly improve the overall contact stability of the device and reduce the risk of displacement or tipping caused by slight shaking or contact with the table. This ensures that the core components such as the interview camera and interview microphone maintain stable images and good sound reception during operation. During height adjustment, the follower cylindrical rod of the follower counterweight stabilizing device can smoothly move up and down within the follower movable hole, ensuring that the solid metal disc plate remains in contact with the tabletop regardless of whether the device is raised or lowered. The stability is not weakened by the lifting operation. The solid metal disc plate is threadedly connected to the threaded hole via a fixed threaded head, allowing for quick assembly and disassembly as needed to adapt to different counterweight requirements. After removing the solid metal disc plate, the follower cylindrical rod can be stored using the magnetic attraction of the magnetic knob and the magnetic anti-detachment sleeve, reducing the protruding structure at the bottom and facilitating the carrying and storage of the entire device when not in use.

[0022] 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.
[0023] This utility model provides, for example Figure 1-6 The multimodal interview support device shown is supported on a table or platform by three outwardly flared and inclined mounting brackets 1. The ball joints at their bottoms provide stable three-point support on the table, ensuring basic stability even when the interview host 8 is not activated. The upper ends of the multiple inclined mounting brackets 1 are connected to the outside of a bracket integrated sleeve 4, which is circumferentially fixed to the bottom periphery of a cylindrical bracket 3, ensuring uniform stress distribution across the entire support structure. The cylindrical bracket 3 extends along its height... The extension is used to support the interview host 8 and its related components above. In the interview scenario, this device can form a stable support structure through the tilting bracket 1, the follow-up counterweight stabilizing device 2 and the disc-shaped solid metal plate 17. The height can be adjusted by the lifting stabilizing sleeve 5 and the hand-tightening height fixing screw 7. Multimodal audio and video collaborative acquisition is achieved through the structure of the interview host 8, interview camera 16, multiple interview microphones 11 and universal bending rod 10. The structures cooperate with each other, so that the whole device can maintain a stable, efficient and flexible working state in the ever-changing interview scenario.
[0024] like Figure 1 , Figure 5 and Figure 6As shown, to improve the stability of the device at different heights, a follower counterweight stabilizing device 2 is installed inside the cylindrical support 3. The follower counterweight stabilizing device 2 consists of a follower cylindrical rod 19, a disc-shaped solid metal plate 17, a fixed threaded head 20, a fixed threaded hole 21, a magnetic knob 18, a magnetic anti-detachment sleeve 22, an anti-detachment sleeve 23, and a follower movable hole 24. The follower movable hole 24 extends from top to bottom inside the cylindrical support 3, and its lower end forms an open structure, allowing the follower cylindrical rod 19 to slide freely from bottom to top. The upper end of the follower cylindrical rod 19 is equipped with an anti-detachment sleeve 23, which keeps it in contact with the follower movable hole 24 during vertical movement. The bottom end is threaded to the center of the solid metal disc 17 via a fixed threaded head 20, which is threaded to the fixed threaded hole 21. This secures the solid metal disc 17 to the bottom of the following cylindrical rod 19 and makes it fit against the table to form additional counterweight. The magnetic anti-slip sleeve 22 is installed inside the opening of the following movable hole 24 to prevent the anti-slip sleeve 23 from sliding down excessively. The magnetic knob 18 is sleeved on the outer wall of the bottom end of the following cylindrical rod 19. After the solid metal disc 17 is removed, it can be pushed up to magnetically attract the magnetic anti-slip sleeve 22, realizing part of the storage function of the following cylindrical rod 19.
[0025] like Figure 1 , Figure 5 and Figure 6 As shown, when the lifting and stabilizing sleeve 5 on the outside of the cylindrical support 3 moves up and down along the cylindrical support 3 to adjust the overall height, the internal threaded cylinder 6 inside the lifting and stabilizing sleeve 5 can be locked or unlocked by the hand-tightening height-fixing screw 7. After the screw of the hand-tightening height-fixing screw 7 is screwed in, it can be pressed against the outer wall of the cylindrical support 3 to stop it from rising and falling. After loosening, the cylindrical support 3 is allowed to slide freely along the inside of the lifting and stabilizing sleeve 5. As the height of the cylindrical support 3 changes, the follower cylindrical rod 19 moves up and down synchronously in the follower movable hole 24, so that the disc-shaped solid metal plate 17 can always be pressed against the table and will not detach from the table due to the raising or lowering of the cylindrical support 3, thereby continuously providing a stable counterweight effect.
[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the interview host 8 is mounted on the top of the cylindrical bracket 3. Its bottom center is inserted into the U-shaped corner sleeve 14 via a rotating connecting block 13. An adjustable pivot is formed between the two using a knob-type screw, allowing the interview host 8 to be tilted forward and backward to adapt to different shooting angle requirements in various interview scenarios. The front of the interview host 8 has a display screen 9 for real-time previewing of the footage or viewing audio, battery, and recording status. The rear has multiple control buttons 15 for switching interview modes and adjusting audio and video parameters. Internally, it integrates a processor and audio / video system for multimodal interview tasks. The rear center of the interview host 8 has an interview camera 16 for capturing video of the interviewee. The top of the interview host 8 has a microphone integration mount 12. Multiple flexible universal rods 10 are fixed on the top, and interview microphones 11 are fixed at the ends of the universal rods 10. The interview microphones 11 can be flexibly adjusted to the front or side of the interviewee through the universal rods 10 to ensure clear and accurate sound reception. Electrical plugs are set on both sides of the bottom of the microphone integrated base 12, which can be electrically connected to the microphone electrical plugs opened on both sides of the top of the interview host 8, providing a stable power supply and signal transmission channel for multiple interview microphones 11. This enables the interview host 8, interview microphones 11 and interview camera 16 to form a collaborative relationship for synchronous audio and video acquisition. The interview host 8 can process and store the acquired video images and audio signals acquired by the interview microphones 11 in a unified manner to realize multimodal interview function.
