  • Product Details

The mobile phone uses dual shafts and adopts a gear structure to achieve synchronous flipping. The flipping damping is determined according to the structure of the customer’s product. The specific technical parameters are as follows:

1. The spring force (6.0±0.8)x2 Kg.f, the elastic force can be adjusted appropriately according to customer requirements. However, the greater the elasticity, the greater the impact on product life.

2. When the working angle of the rotating shaft is open 0°~167°, 0°, 167°, 347°, there is a positioning feel. 0° preload 13°, 360° rotation unlimited Bit.

3. Hand feeling requirements: 0 degree snapping screen, strong hand feeling, 167°, 347° positioning sense is obvious.

4. Shipping angle: open to 167°.

5. Lifetime requirement: 100,000 times, test angle: 0°-165°, 3-4S/round, one round is once, attenuation rate ±30%.5. span>

6. After the shaft is assembled to the whole machine, skewing, warping, screen drop, and gap deviation are not allowed.

7. Pay attention to the assembly direction of the product and the mobile phone case
