Magnetic type vehicular mobile phone bracket based on universal ball

Abstract

The invention discloses a magnetic type vehicular mobile phone bracket based on a universal ball. The magnetic type vehicular mobile phone bracket comprises a vehicle body fixing component, a base (1), a ferromagnetic metal universal ball (2) and a permanent magnet suction ring (3), wherein the base (1) is composed of a hard part (1.1) and a soft part (1.2), and the universal ball is in pressed adhesion with an upper surface of the soft part (1.2) by an adhesive; and when the maximum thickness of an outer edge of an elastic gasket (5) is slightly greater than the thickness of the permanent magnet suction ring (3), the elastic gasket (5) is pressed to shrink, and the elastic gasket (5) jacks the surface of a metal magnetic suction piece (4) under the action of an elastic force. According to the magnetic type vehicular mobile phone bracket disclosed by the invention, the adhesion effect of the soft part and the universal ball is good, so that the universal ball is unlikely to fall off. The thickness of the elastic gasket is slightly greater than the thickness of the permanent magnet suction ring, after a mobile phone is mounted, the metal magnetic suction piece sucks the permanent magnet suction ring, the elastic gasket is pressed to shrink and jacks the metal magnetic suction piece under the action of the elastic force, so that the normal pressure of the contact surface is increased, the friction force is increased, and the mobile phone can be placed more stably.

Description

technical field [0001] The invention relates to a magnetic suction type vehicle-mounted mobile phone holder based on a universal ball. Background technique [0002] The universal ball mobile phone holder has a compact structure, flexible and convenient use, and a stylish appearance, and has been favored by more and more users. However, the base of the traditional universal ball mobile phone holder is made of one-piece hard material, and the base and the metal universal ball are glued together. Due to the problem of processing accuracy, there are pits on the concave surface of the base and the surface of the universal ball. It is difficult to completely fit between the base and the metal universal ball, and there are likely to be gaps between them. When using glue, there are likely to be air bubbles, and the adhesion effect is poor, especially after long-term sun exposure, the glue that is in contact with the air in the air bubbles It is easy to age at high temperature and l...

However, the base of the traditional universal ball mobile phone holder is made of one-piece hard material, and the base and the metal universal ball are glued together. Due to the problem of processing accuracy, there are pits on the concave surface of the base and the surface of the universal ball. It is difficult to completely fit between the base and the metal universal ball, and there are likely to be gaps between them. When using glue, there are likely to be air bubbles, and the adhesion effect is poor, especially after long-term sun exposure, the glue that is in contact with the air in the air bubbles It is easy to age at high temperature and lose its viscosity, and the metal universal ball is easy to fall off from the base

This is the bottleneck of the service life of traditional mobile phone holders

[0003] On the other hand, the suction force between the metal magnetic attraction piece and the permanent magnet suction ring of the traditional universal ball mobile phone holder can ensure that the metal magnetic attraction piece (mobile phone) is not easy to fall off in the axial direction, but due to the heavy weight of the mobile phone, the hard The surface of the high-quality metal magnetic attraction piece and the hard permanent magnet suction ring is smooth, the friction coefficient of the contact surface is very small, and the metal magnetic attraction piece is easy to slip in the radial direction

Especially when the car encounters a bumpy road, the mobile phone is not placed stably, and it is easy to slip off the bracket
