Description

Device with magnet structure

Technical Field

The invention relates to a device comprising two shells respectively provided with a bulge structure and a pit structure, wherein the two shells are tightly attached through the attraction of magnets in the two shells, and the two shells cannot slide relative to each other through the matching of the bulge structure and the pit structure.

Background

In life, it is often necessary to secure a mobile device vertically or obliquely, temporarily, but reliably, in a location, such as an air outlet of an automobile. Therefore, the adjustable clamp structure is invented to realize fixation through clamping, or the magnet adsorbs a ferromagnetic material arranged on the mobile equipment to realize fixation.

However, in practice, the clip structure tends to be large in size, ugly in appearance, limited in the size of the mobile device to which it is fitted, and the clip structure has a short life and sometimes requires two-handed operation. And the mode of magnet adsorption ferromagnetic material, when the tangential force perpendicular to magnet adsorption power appears, lead to mobile device and magnet relative slip, lead to ferromagnetic material and magnet to keep away from and then the adsorption power weakens and the phenomenon that final mobile device drops is difficult to solve.

Therefore, a structural design method suitable for temporarily fixing the mobile equipment, which has the advantages of small size, wide adaptation range, high reliability, long service life and suitability for single-hand operation, needs to be provided, and meets the social requirements.
