Wireless charging bracket damping shaft Bluetooth earphone box electronic flip product shaft damper manufacturer

Description :

1、 Product Design Proposal: Wireless Charging Stand/Bluetooth Earphone Box Exclusive Micro Damping Structure

Bluetooth earphone case and wireless charging bracket belong to micro precision digital products, with a rotating shaftVolume size, damping force, opening and closing feel, assembly thickness, module compatibilityThe requirements are extremely high. Ordinary large damping shafts are too hard, thick, prone to top shell, and have severe rebound, making them unsuitable for lightweight digital devices. Our factory has optimized the micro precision damping design scheme to fully meet the structural design and usage requirements of small flip electronic products.

Soft and stepless stop and rebound prevention designAdopting a micro multi-layer precision friction damping structure, the earphone case is designed with ultra light weight and wireless charging bracket light load characteristics, and the gentle torque is precisely adjusted to achieve seamless and arbitrary stopping of the flip cover from 0-180 °. The lid does not rebound, self fasten, or automatically close when opened, and the bracket angle adjustment does not fall or deviate. The user's opening and closing feel is delicate and high-end, solving the low-end texture problems of ordinary hinge opening and closing hands, loose closure, and unstable angle fixation in the market.

Ultra thin micro anti-interference structureThe overall structure is extremely streamlined and thin, specially optimized for areas with dense coils and induction modules inside wireless charging devices. It has no protruding structure, no top shell, and does not interfere with wireless charging functions, without affecting charging induction efficiency. Perfectly compatible with Bluetooth earphone case with small cavity embedded invisible installation, does not damage the appearance of the body, and conforms to the trend of lightweight and simple design of digital products.

Silent, smooth and wear-resistant structureOptimize the internal friction clearance ratio, with no dryness, stuttering, or metal impact noise during the opening and closing process. The entire process is quiet and gentle, meeting the requirements of high-end digital product silence texture. At the same time, avoid frequent opening and closing of the grinding shell and scratching of the body, and protect the integrity of the product's appearance.

Long lasting anti-aging micro locking structureFor the daily high-frequency opening and closing of the headphone case and the repeated angle adjustment of the wireless charging bracket, we have upgraded the micro pre pressure locking structure, which provides long-lasting and stable torque. It can be opened and closed tens of thousands of times without loosening, slipping, or damping attenuation. We can customize the torque size, shaft length, and installation structure according to the customer's product feel requirements, body thickness, and installation hole spacing, and adapt to new product private mold development, old model iteration, and large-scale production matching.

2、 Material and process: Micro precision high-strength material, delicate and wear-resistant, rust proof and fatigue resistant

For daily handheld use of Bluetooth earphone cases and wireless charging stands, exposure to sweat, humid air, pocket storage friction, and high-frequency opening and closing environments, this miniature damping shaft is carefully selectedHigh toughness precision carbon steel materialThe material is pure and dense, with uniform hardness and high toughness, balancing ultra-thin body shape and structural strength. It fully meets the environmental protection material standards of 3C digital and consumer electronics, and solves the problems of easy deformation, rusting, dry hand feel, fast damping attenuation, and easy jamming of micro shafts from the root.

Integrated precision molding processThe shaft core, damping surface, and installation position are integrally forged and formed without splicing or welding breakpoints. The microstructure has stable strength and will not break, eccentric, or deform due to frequent opening and closing. It always maintains high concentricity rotation and opens and closes evenly and smoothly.

Damping surface CNC precision grinding and hardening processThe core damping friction surface has undergone high-frequency quenching and hardening+micrometer level precision grinding treatment. The friction surface is delicate and smooth, with uniform fit clearance. The damping output is linear and soft, without sudden tightening or loosening, and without mechanical hard impact, perfectly restoring the delicate opening and closing feel of high-end digital products.

Digital grade rust and corrosion prevention technologyThe surface is treated with precision thickened electroplating and passivation sealing, with a delicate and firm coating that is not easily peeled off. It effectively resists sweat on the hands, humidity in the air, and daily friction oxidation, preventing micro shafts from rusting, blackening, lagging, and rotating failure. The appearance remains new and the hand feel remains unchanged after long-term use.

3、 Product performance testing: salt spray test+10000 opening and closing fatigue test

Our factory produces miniature digital damping shafts strictly in accordance with the quality standards of high-end 3C digital accessories, and conducts full batch sampling and testing to ensure the quality and reputation of end products through rigorous testing.

Industrial salt spray anti-corrosion testingThrough standardized industrial salt spray corrosion resistance testing, simulate daily conditions such as sweat erosion, oxidation in humid environments, and dust accumulation. After testing, the shaft has no rust spots, no oxidation or whitening, no coating peeling off, smooth opening and closing without jamming, excellent moisture and rust resistance, and completely solves after-sales problems such as rusting, lagging, and poor hand feel of the shaft after long-term use of the headphone case and wireless charging bracket.

10000 times high-frequency opening and closing fatigue testAfter tens of thousands of frequent cycles of flipping, opening, and hovering fatigue tests, the shaft structure has no deformation, extremely low torque attenuation, no looseness or shaking, and no rebound failure. Long term high-frequency use provides a unified tactile sensation, stable hovering, no looseness, and no abnormal noise, significantly reducing the repair rate of digital products and ensuring the long-term high-end texture of the products.

Silent tactile testThe entire opening and closing process is silent and noiseless, with a soft and even touch, suitable for high-end digital product quality positioning, enhancing user experience and product premium.
