Abstract
The present disclosure relates to the technical field of the permanent-magnetic track, and discloses a magnetic track module, a composite permanent-magnetic track and an installation method thereof. The magnetic track module comprises: at least two layers of magnetic units that are staggered in the first direction and stacked in the second direction with the same magnetization direction, wherein each magnetic unit is formed by a plurality of closely-arranged permanent magnets; and a bottom ferromagnetic plate that covers the lower surface of the bottom magnetic unit, with an attractive magnetic force existing between the bottom ferromagnetic plate and the adjacent magnetic unit.

A magnetic track module, comprising:
- at least two layers of magnetic units that are staggered in a first direction and stacked in a second direction with the same magnetization direction, wherein each magnetic unit is formed by a plurality of permanent magnets that share the same magnetization direction and are arranged closely in the first direction, and the magnetization direction is along the second direction;
- a bottom ferromagnetic plate that covers a lower surface of the bottom magnetic unit, with an attractive magnetic force between the bottom ferromagnetic plate and the adjacent magnetic unit;
- under the attractive magnetic forces between two adjacent magnetic units and between the bottom ferromagnetic plate and the adjacent magnetic unit, static frictional forces are generated between two adjacent magnetic units and between the bottom ferromagnetic plate and the adjacent magnetic unit and are able to balance out all or part of the repulsive magnetic forces between two adjacent permanent magnets in the same magnetic unit;
- and
- a protective sleeve made of a non-ferromagnetic material, and the protective sleeve has an accommodating space fitting the magnetic units and the bottom ferromagnetic plate and two openings at the two ends in connection with the accommodating space;
- the magnetic units and the bottom ferromagnetic plate are partially wrapped in the protective sleeve, so that the magnetic units maintain the staggered and stacked layout and form two connecting structures at the two ends of the protective sleeve,
- wherein the staggered layout between two adjacent magnetic units refers to that the gap between two adjacent permanent magnets in one magnetic unit is located at the middle of the permanent magnet in the adjacent magnetic unit,
- wherein the two connecting structures comprise a connecting cavity and a connecting protrusion that fit in with each other and are formed at the two ends of the protective sleeve respectively;
- the connecting cavity is formed by the staggered displacement between the two magnetic units and the wall of the protective sleeve;
- and the connecting protrusion is formed by the protruding part of the permanent magnet out of the protective sleeve.
