1、 Product design scheme: Exclusive damping structure design for mobile phone holder

Mobile phone and tablet holders belong to high-frequency portable digital accessories, and the core requirements for the hinge areAdjustable angle, wide torque adaptation, hover without falling, silent and smooth, lightweight without top shellOur factory combines various working conditions such as desktop drama watching, live streaming support, in car fixation, and portable storage to optimize the exclusive damping structure and adapt to the mass production and assembly needs of all types of mobile phone stands.

Adjustable and precise torque designAdopting multi-layer stacked adjustable damping friction components, supporting torque fine-tuning adaptation, it can accurately match damping force according to different load-bearing capacities of mobile phones and tablets, completely solving the problem of poor single torque adaptation of ordinary shafts, and eliminating the common problems of small equipment jamming and large equipment falling. The torque output is linear and uniform, the angle adjustment is moderate, the hand feel is delicate and high-end, and it is suitable for various types of brackets with fine angle adjustment needs.

Stepless arbitrary stop anti shake hovering structureRealize 0-360 ° full range rotation, 0-180 ° flip cover limit bidirectional structure optional, stepless self-locking throughout the process, stop when released, and precise locking at any angle. No rebound, no shaking, no falling, effectively resisting desktop touch vibration, car driving bumps, and slight shaking of live streaming equipment. The bracket angle remains constant for a long time without deviation, without the need for repeated debugging. It is stable throughout movie watching, live streaming, and car navigation use.

Ultra thin universal adaptive structureThe overall structure is concise and compact, with a thin and light thickness, optimized for the narrow cavity of the bracket. It can be embedded and installed invisibly, without occupying internal space, top shell, or damaging the minimalist appearance of the bracket. Compatible with various shell materials such as plastic, aluminum alloy, and metal magnetic brackets, suitable for rapid assembly on automated assembly lines, easy to assemble, and high yield rate. Optional hollow wire structure, suitable for carrying wires and magnetic charging brackets, avoiding repeated folding and pulling of worn wires, and protecting the safety of equipment circuits.

Long term silent and anti attenuation structureOptimize the internal clearance ratio and pre pressure locking process, ensure stable friction fit, eliminate abnormal noise caused by metal hard friction, and ensure smooth and quiet folding and rotation angle adjustment without any dryness or jamming. Long term high-frequency folding and vibration use with damping force that does not slip, decay, or loosen, providing a consistent and stable hand feel after tens of thousands of uses. We can customize one-on-one according to customer bracket size, load-bearing specifications, installation hole spacing, and hand feel requirements, adapting to new product development, old model upgrades, and private model upgrades for mass production.

2、 Material and process: High strength and wear-resistant material, rust and fatigue resistance, stable hand feel

For the use of mobile phone holders in multiple scenarios such as home, office, and car use, long-term exposure to air, exposure to sweat and water vapor, frequent folding and angle adjustment, and bumpy vibrations, this holder's damping shaft is carefully selectedHigh toughness precision industrial carbon steel materialThe material is dense and uniform, with moderate hardness and excellent toughness, balancing micro volume and structural strength. It has outstanding resistance to deformation, wear, and fatigue, fully meeting the environmental protection material standards for consumer electronics and digital accessories. It solves quality problems such as easy deformation, rusting, damping failure, jamming noise, and long-term looseness of bracket shafts from the root.

Integrated precision forging and forming processThe main body, core, mounting base, and damping structure of the shaft are integrally forged and formed without any splicing gaps or weak welding points. The overall structural strength is high and the force is uniform and stable. Eliminate welding eccentricity, structural looseness, cracking and deformation defects. Long term repeated folding, rotation, bouncing and vibration are not easy to loosen, and always maintain ultra-high rotational concentricity. The bracket angle adjustment is smooth without eccentric shaking.

Micro scale precision grinding and hardening process for damping surfaceThe core damping friction working surface is treated with high-frequency quenching and hardening+CNC micron level precision grinding technology. The friction surface is smooth and delicate, and the clearance between components is precise and controllable. The damping torque output is linear and uniform throughout the entire process, without sudden tightening, loosening, dryness, or mechanical hard impact. The folding and rotating feel is soft and smooth, greatly improving the high-end texture of the digital bracket.

Digital grade moisture-proof and rust proof processThe surface is treated with thickened precision electroplating and passivation sealing composite anti rust treatment. The coating is thick and dense, with strong adhesion and is not easy to peel off. It can effectively isolate moisture, air dust, hand sweat, and vehicle temperature difference corrosion, and prevent rusting, blackening, jamming, and rotation loss of the shaft. It is resistant to moisture, aging, frequent friction, and suitable for long-term stable use in multiple scenarios.

3、 Core performance guarantee: salt spray test+10000 fold fatigue test

Our factory's mobile phone holder dedicated damping shaft is strictly produced according to high-end digital accessory quality standards, with full batch sampling testing and multiple performance retests to ensure long-term stability of end products and reduce customer after-sales failure rates with strict industrial testing standards.

Industrial salt spray anti-corrosion testingThrough standardized neutral salt spray corrosion resistance testing, simulate complex working conditions such as home humidity, vehicle temperature difference, sweat corrosion, and dust accumulation. After testing, the shaft has no oxidation white spots, rust spots or corrosion, no coating peeling off, and no shaft jamming. It has excellent moisture resistance, rust prevention, oxidation resistance, and corrosion resistance, completely solving the after-sales problems of long-term use of the bracket, such as rusting, lagging, unsmooth rotation, aging appearance, and poor hand feel of the shaft.

Ten thousand fold rotation fatigue testAfter tens of thousands of multi angle adjustments, 360 ° rotations, repeated folding and storage, hovering and self-locking cyclic fatigue tests, the shaft structure has no deformation, no concentricity offset, extremely low torque attenuation, and constant positioning accuracy. Long term high-frequency use ensures no looseness, no falling, no abnormal noise, and no damping failure, continuously guaranteeing stable bracket angles and precise positioning, greatly extending the service life of the entire bracket.

Silent anti shake+torque stability testHigh concentricity axis core design, rotation without eccentric shaking, effectively resisting bumps, vibrations, and external contact; Precise gap ratio achieves full silent and noise free operation, suitable for various quiet usage scenarios such as home TV shows, office and study, car navigation, live streaming, etc., with long-lasting damping performance that does not degrade.
