Description

Technical Field

[0001] This utility model relates to the field of mixing console technology, specifically to a display screen angle adjustment structure for a digital mixing console. Background Technology

[0002] As core equipment in the broadcasting and professional audio fields, the human-computer interaction interface of digital mixing consoles, especially the display panel, is crucial to the work efficiency and comfort of operators.

[0003] However, existing digital mixing consoles typically use a rigid, fixed connection between the display panel and the console body. Since operators of different heights have significantly different eye levels and viewing angles, a fixed-oriented display panel cannot be adjusted to suit the user's viewing needs. Users must frequently adjust their head or body posture to obtain clear display content, and prolonged viewing at an off-center angle can easily lead to neck and shoulder fatigue, and even visual discomfort. This not only reduces comfort during long working hours but also affects operational accuracy and overall work efficiency. Therefore, we propose a display panel angle adjustment structure for digital mixing consoles. Utility Model Content

[0004] The purpose of this invention is to provide a display screen angle adjustment structure for a digital mixing console to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a display screen angle adjustment structure for a digital mixing console, comprising an operating console body, a display panel, and an adjustment component; the adjustment component includes a main support and a secondary support connected in sequence; a bottom fixing frame rotatably connected to the main support; and a top fixing frame rotatably connected to the secondary support and used to fix the display panel.

[0006] Preferably, the bottom bracket is fixed to the control panel body, and the top bracket is fixed to the bottom of the display panel.

[0007] Preferably, the connection between the bottom fixing frame and the main support, the connection between the main support and the secondary support, and the connection between the secondary support and the top fixing frame are all provided with threaded rods that pass through the two, with both ends of the threaded rods protruding from the connection.

[0008] Preferably, nuts are symmetrically provided at both ends of the screw. By tightening the two nuts together, the friction at the connection point is increased, thereby locking the orientation of the display panel.

[0009] Preferably, an integrally formed connecting rod is fixed between two symmetrically distributed screws at the connection between the main support and the auxiliary support.

[0010] Preferably, annular gaskets are provided at the connection points between the bottom fixing frame and the main support, the main support and the secondary support, and the secondary support and the top fixing frame.

[0011] Preferably, the annular gasket is made of nylon.

[0012] Preferably, the rotation axes of the main support and the auxiliary support are parallel to each other.

[0013] Compared with traditional technologies, the beneficial effects of this utility model are:

[0014] This device features an adjustment assembly consisting of a main support and a secondary support, which are rotatably connected to a bottom fixed frame and a top fixed frame, respectively. This allows for flexible multi-angle adjustment of the display panel relative to the control panel. This enables operators of different heights to easily adjust the display panel to the most comfortable viewing angle according to their own eye level and viewing needs, without frequently adjusting their head or body posture. This effectively avoids neck and shoulder muscle fatigue and visual discomfort caused by prolonged viewing of the screen at an off-center angle, improving comfort during extended operation and indirectly enhancing operational accuracy and overall work efficiency.

[0015] By utilizing screws that run through each rotating connection (between the main bracket and the secondary bracket, and between the secondary bracket and the top fixing frame) and nuts symmetrically arranged at both ends, operators can tighten the nuts at both ends to bring them closer together, thereby precisely increasing the friction at the connection points. This design ensures that the display panel can be stably and reliably locked after being adjusted to any desired angle, effectively preventing accidental displacement or angle changes of the display panel due to touch or vibration during use, ensuring stable visibility of the displayed content, and guaranteeing the continuity and reliability of the audio adjustment operation.

[0016] By installing annular gaskets at each rotating connection point, especially when using nylon, direct contact wear between the metal parts of the bracket and the fixed frame during rotation and friction can be reduced. This ensures smooth angle adjustment, improves the overall durability and service life of the adjustment component, reduces the risk of structural loosening or failure due to frequent adjustments over a long period, ensures long-term stable operation of the angle adjustment function, and reduces maintenance requirements.

[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] Example 1:

[0024] Please see Figures 1-4 The diagram illustrates a digital mixing console's display screen angle adjustment structure, comprising a console body 1, a display panel 2, and an adjustment assembly 3. The adjustment assembly 3 includes a main support 4 and a secondary support 5 rotatably connected in sequence. The series rotatable connection between the main support 4 and the secondary support 5 forms a dual-degree-of-freedom hinge system, allowing the display panel 2 to be adjusted for both tilt and forward / backward movement simultaneously. A bottom fixing bracket 6 is rotatably connected to the main support 4, and a top fixing bracket 7 is rotatably connected to the secondary support 5 and used to fix the display panel 2. This three-level linkage design overcomes the limitations of traditional rigid connections, enabling the display screen to adapt to the viewing angle needs of operators of different heights.

[0025] The following describes some embodiments of this application in detail with reference to the accompanying drawings:

[0026] Please see Figures 1-4 By setting up an adjustment assembly 3 consisting of a main support 4 and a secondary support 5, and rotatably connecting it to the bottom fixing bracket 6 and the top fixing bracket 7 respectively, the display panel 2 can be flexibly adjusted at multiple angles relative to the operating console body 1. This allows operators of different heights to easily adjust the display screen to the most comfortable viewing angle according to their own eye level and viewing needs, without having to frequently adjust their head or body posture. This effectively avoids neck and shoulder muscle fatigue and visual discomfort caused by prolonged viewing of the screen at a non-direct viewing angle, improving comfort during long-term operation and indirectly improving operational accuracy and overall work efficiency.

[0027] The bottom mounting bracket 6 is fixed to the operating table body 1, forming a stable force transmission base point, while the top mounting bracket 7 is fixed to the bottom of the display panel 2, ensuring the stability of the panel's center of gravity while avoiding obstruction of the display area. This top-bottom separated positioning design ensures that the adjustment component 3 is subjected to uniform force and that the panel adjustment trajectory is always parallel to the operator's line of sight, avoiding screen distortion caused by asymmetrical support.

[0028] In this technical solution, threaded rods 8 are provided at the connection points of the bottom fixing frame 6 and the main support 4, the main support 4 and the auxiliary support 5, and the auxiliary support 5 and the top fixing frame 7, with both ends of the threaded rods 8 protruding from the connection points. These two ends of the threaded rods 8 extend beyond the connection points to form dual operating ends. This structure, on the one hand, defines a precise rotation pivot through the axis of the threaded rods 8, ensuring that each support rotates around a single axis; on the other hand, the exposed operating ends provide a physical interface for the subsequent locking mechanism, and their symmetrical extension characteristics can balance the locking forces on both sides, preventing uneven load friction during adjustment.

[0029] Furthermore, nuts 9 are symmetrically provided at both ends of the screw 8. By tightening the two nuts 9 together, the friction at the connection point is increased, thereby locking the orientation of the display panel 2. The nuts 9 on both sides are simultaneously screwed in using a tool, causing them to move towards each other along the axial direction of the screw 8. The inner end face of the nut 9 presses against the side wall of the connection point, generating radial pressure, which presses the metal contact surfaces of the rotating pair together to form a static friction field. This friction force increases linearly with the depth of screwing in the nut 9, ultimately achieving stepless control from free adjustment to complete locking, ensuring that the display panel 2 can maintain the set angle even under strong vibration environments.

[0030] In addition, annular gaskets 11 are provided at the connection points of the bottom fixing bracket 6 and the main bracket 4, the main bracket 4 and the auxiliary bracket 5, and the auxiliary bracket 5 and the top fixing bracket 7. The inner hole of the gasket is clearance-fitted with the screw 8 to form a sliding bearing structure. The annular gaskets 11 made of nylon perform three functions: first, the self-lubricating properties of nylon reduce the coefficient of metal friction, thereby reducing the angle adjustment operation force; second, the elastic deformation absorbs assembly tolerances; and finally, it acts as an insulating layer to block the electrochemical corrosion path between the brackets, extending the service life.

[0031] In this technical solution, the rotation axes of the main support 4 and the secondary support 5 are parallel to each other. This coplanar non-intersecting axis layout transforms the motion trajectory of the display panel 2 into a composite translation-rotation motion. Compared to the staggered axis design, the parallel axis structure ensures that the center point of the panel always moves in an arc within a fixed plane, avoiding the phenomenon of viewing center shift and allowing the operator to obtain a distortion-free frontal visual experience from any angle.

[0032] The working principle of this device is as follows:

[0033] When the operator applies external force to the display panel 2: the connection between the bottom fixing bracket 6 and the main bracket 4 first rotates around the axis of the screw 8, causing the entire bracket system to make an initial pitch adjustment with the bottom as the center; the linkage is transmitted to the connection between the main bracket 4 and the auxiliary bracket 5, and the auxiliary bracket 5 rotates a second time relative to the main bracket 4, expanding the adjustment range; finally, the composite rotation is transmitted to the display panel 2 through the top fixing bracket 7.

[0034] At this time, the annular gaskets 11 at all the joints play a lubricating role, reducing the sliding friction coefficient of the metal contact surface and enabling one-handed light operation;

[0035] During the adjustment process, the two supports form a parallelogram linkage mechanism, which forces the display panel 2 to perform planar movement; the center point of the panel moves along an arc trajectory with a fixed radius of curvature to avoid the center of the viewing angle shifting.

[0036] When the panel is adjusted to the target angle: tighten the symmetrical nuts 9 at both ends of the screws 8 at each node, causing the nuts 9 to move towards each other along the axial direction of the screws 8; the inner end face of the nut 9 presses against the side wall of the connection, and the radial pressure is converted into static friction force on the contact surface through the annular washer 11; the friction torque increases linearly with the tightening degree of the nuts 9, forming a three-node synchronous locking. This process utilizes the lever arm advantage of the two operating ends of the screw 8, and full locking can be completed with only a single wrench;

[0037] In vibrating environments or during continuous operation: the elastic deformation of the nylon annular gasket 11 absorbs micro-vibrations and prevents accidental loosening; the pressure distribution design of the three-stage rotating node evenly distributes the panel's weight to the bottom fixing frame 6; the operator can continuously lock the optimal viewing angle within a suitable pitch range according to height differences to prevent neck fatigue.

[0038] Example 2:

[0039] This embodiment is an optimization of the structure in Embodiment 1. Specifically, as follows: Figure 3 As shown, an integrally formed connecting rod 10 is fixed between two symmetrically distributed screws 8 at the connection between the main support 4 and the auxiliary support 5. This connecting rod 10 constrains the two originally independent screws 8 into a rigid synchronous body, forcing the connection points on both sides to move at equal intervals. This design eliminates the risk of asymmetric deformation during dual-axis adjustment, ensuring that the panel pitch adjustment trajectory always maintains planar motion characteristics, while increasing the bending strength of the connection part by increasing the moment of inertia of the cross section.
