Referring to fig. 1 and 2, fig. 1 is a schematic structural diagram of a magnetic-type watchband in the prior art, wherein the arrow direction in the diagram indicates the magnetic induction line direction, and fig. 2 is a schematic structural diagram of two magnetic-type watchbands in the prior art that are attracted to each other; the existing magnetic-type watchband 1 ' is provided with protruding structures 4 ', the adjacent protruding structures 4 ' are arranged at intervals, the magnet is located in the protruding structures 4 ', and referring to fig. 2, the most protruding position of the protruding structure 4 ' is a contact position for being adsorbed and fixed with the contact position of another watchband. The magnet in the protruding structure is stronger because the magnetism of most outstanding position department, and the adsorption of most outstanding position to most outstanding position is inclined to most outstanding position of watchband nature, as shown in fig. 2, results in the clearance that exists between two watchbands great to influence user's the experience of wearing.

To the problem, the embodiment of the utility model provides a magnetic component and can join in marriage band table can realize that the protruding is adsorbed to concave dislocation between two area bodies, and it is more inseparable to laminate between two area bodies, improves the adsorption strength, and two band bodies are difficult for separating.

The technical solution provided by the present invention is explained in more detail with reference to fig. 3 to 16.

Referring to fig. 6-9, the direction of the arrows in fig. 8 indicate the direction of the magnetic induction lines; the embodiment provides a magnetic assembly, which comprises a first belt body 1 and a second belt body 2, wherein the first belt body and the second belt body are respectively provided with a plurality of protruding structures 4 which are arranged at intervals, the protruding structures 4 protrude along the thickness direction of the corresponding belt body, and a magnetic unit 3 is fixed inside the absorption side of each protruding structure 4; the magnetic unit 3 comprises a first magnetic part 31 and a second magnetic part 32, and the magnetization directions of the first magnetic part and the second magnetic part both form a nonzero included angle with the thickness direction and the length direction of the corresponding belt body; when the protruding structure 4 of the first belt body 1 extends into the space between the adjacent protruding structures 4 of the second belt body 2, the first belt body 1 and the second belt body 2 can be fixed in an adsorption manner.

Most of the magnetic members can be magnetized to saturation in the same direction, which is called "magnetization direction" (orientation direction). A magnet without an orientation direction (also called an isotropic magnet) is much weaker in magnetic properties than an oriented magnet (also called an anisotropic magnet). For each magnetic member, there is a direction in which the minimum and maximum energy of the magnetic crystal is required, the former being called easy magnetization direction and the latter being called hard magnetization direction.

Wherein "the thickness direction of the corresponding tape" refers to the up-down direction as in fig. 6 to 8, and "the length direction of the corresponding tape" refers to the left-right direction as in fig. 6 to 8. In this embodiment, when the protrusion structure 4 is viewed from one side of the belt body, that is, the radial cross section of the protrusion structure 4 is an ellipse, the magnetization direction of the first magnetic member 31 and the magnetization direction of the second magnetic member 32 both have a non-zero included angle with the major axis and the minor axis of the radial cross section of the protrusion structure 4.

The magnetic component of this embodiment, all set up magnetic unit 3 in the protruding structure 4 of the first area body 1 and the second area body 2, magnetic unit 3 includes first magnetism piece 31 and second magnetism piece 32, there is nonzero contained angle between the magnetization direction of first magnetism piece 31 and the magnetization direction of second magnetism piece 32 all and the thickness direction and the length direction that correspond the area body, and thus, protruding structure 4 of the first area body 1 can stretch into between the adjacent protruding structure 4 of the second area body 2, the protruding concave dislocation of formation is protruding to the concave absorption, it is more inseparable to laminate between two area bodies, and the adsorption strength is improved, and two area bodies are difficult for the readily releasable.

As an alternative embodiment, referring to fig. 6 to 9, the magnetization direction of the first magnetic member 31 and the magnetization direction of the second magnetic member 32 face to the same side of the corresponding belt body, and an included angle α exists between the two, as shown in fig. 9, where α has a value range of: alpha is more than 0 degree and less than or equal to 120 degrees. Preferably, the angle α between the magnetization direction of the first magnetic member 31 and the magnetization direction of the second magnetic member 32 is 120 °.

The principle that the first belt body 1 and the second belt body 2 can form convex-concave staggered adsorption in the embodiment is as follows:

magnetic members such as neodymium-iron-boron magnets and samarium-cobalt magnets have the characteristic of magnetocrystalline anisotropy, and the magnetocrystalline anisotropy refers to that the magnet (magnetic member) has the strongest magnetism in only one direction, and is also called as an easy magnetization direction. Referring to fig. 3, in the drawing, the direction a represents the magnetization direction, and the direction b represents the easy magnetization direction, even if the magnetic field and the easy magnetization direction deviate from each other by an angle during magnetization, the effect after magnetization is not affected as long as the magnetization magnetic field is large enough, and the same effect as the effect obtained by the direction of the magnetization magnetic field and the easy magnetization direction forms the strongest magnetic field in the easy magnetization direction, and the surfaces with strongest magnetism will be aligned together during natural adsorption.

Wherein, use neodymium iron boron magnetism iron boron magnet as the example, the magnetic part need pass through following process in proper order when production: the method comprises the steps of material preparation, rapid hardening and casting, crushing, jet milling, orientation compression, sintering, magnetic detection, machining, surface treatment and magnetization. The direction of easy magnetization of the magnetic member is determined at the time of orientation molding.

If an included angle is formed between the easy magnetization directions of the two magnets (magnetic members), the attraction magnets (magnetic members) corresponding to the matching belt body also form an included angle and are taken as a whole, because the magnetic field in the easy magnetization directions is strongest, the strongest attraction force is formed when the easy magnetization directions of the two magnets are opposite, and then the effect of dislocation adsorption occurs, as shown in fig. 4.

If each magnetic unit 3 in the first and second belts 1, 2 has two magnetization directions, the convex structures 4 of the first belt 1 can extend into between the adjacent convex structures 4 of the second belt 2, i.e. forming a convex-concave staggered adsorption, as shown in fig. 5.

However, since a single magnetic member has only one easy magnetization direction, it is difficult to form the magnetic unit 3 having two magnetization directions.

In order to solve the above problem, referring to fig. 6-8, in the same magnetic unit 3, the first magnetic member 31 and the second magnetic member 32 have the attaching sides 30 (see fig. 6), and the attaching sides 30 of the two are connected to each other to fix the first magnetic member 31 and the second magnetic member 32. The attachment sides 30 of the first and second magnetic members 31 and 32 may be connected by adhesive fixation.

From this, can realize having two magnetization directions in a magnetic unit 3, and two magnetization directions of same magnetic unit 3 are towards the homonymy that corresponds the area body, have contained angle alpha between these two magnetization directions, as figure 9, wherein, the value range of alpha is: alpha is more than 0 degree and less than or equal to 120 degrees.

Specifically, referring to fig. 6 to 8, as an alternative embodiment, in the magnetic unit 3 of the first belt body 1, both the attaching sides 30 of the first magnetic member 31 and the second magnetic member 32 are S-poles, and both the positions of the first magnetic member 31 and the second magnetic member 32 departing from the attaching sides 30 are N-poles; in the magnetic unit 3 of the second belt body 2, the attaching sides 30 of the first magnetic member 31 and the second magnetic member 32 are both N poles, and the positions of the first magnetic member 31 and the second magnetic member 32 departing from the attaching sides 30 are both S poles; and the magnetization directions of the two corresponding magnetic pieces mutually attracted by the first belt body 1 and the second belt body 2 are the same.

Specifically, referring to fig. 6 to 8, the direction of the arrow in fig. 8 indicates the direction of the magnetic induction line; in one of the magnetic units 3 of the first belt body 1, the magnetization directions of the first magnetic member 31 and the corresponding magnetic member attracted to the second belt body 2 are the same, and the magnetization directions of the second magnetic member 32 and the corresponding magnetic member attracted to the second belt body 2 are also the same, so that the maximum strength of attraction between the first belt body 1 and the second belt body 2 can be ensured.

Since the first belt body 1 has the S-pole attached side of the first magnetic member 31 and the second magnetic member 32, and the second belt body 2 has the N-pole attached side of the first magnetic member 31 and the second magnetic member 32, as shown in fig. 6, in order to prevent the repulsion of like polarities, which makes the connection of the first magnetic member 31 and the second magnetic member 32 difficult, in actual processing, the attached sides 30 of the first magnetic member 31 and the second magnetic member 32 may be bonded and fixed, and then the whole magnetic unit 3 is magnetized. When magnetizing, even if the magnetizing magnetic field and the easy magnetization direction deviate from each other by an angle, as long as the magnetizing magnetic field is large enough, the effect after magnetizing is not affected, and the strongest magnetic field can be formed in the magnetizing direction.

The first magnetic member 31 and the second magnetic member 32 can be fixed without repulsive separation by bonding and fixing the bonded sides 30 of the first magnetic member 31 and the second magnetic member 32 and then magnetizing the entire magnetic unit 3 as a whole.

As an alternative embodiment, the first magnetic member 31 and the second magnetic member 32 are both magnets with magnetic anisotropy, such as neodymium-iron-boron magnet and samarium-cobalt magnet, and the materials of the first magnetic member 31 and the second magnetic member 32 are the same or different, preferably, the materials and the structures of the first magnetic member 31 and the second magnetic member 32 are completely the same, so as to improve the stability of the adsorption structure of the first belt body 1 and the second belt body 2 and improve the adsorption strength.

As an alternative embodiment, the radial cross section of the protruding structure 4 is a circular cross section or an elliptical cross section, the first magnetic member 31 and the second magnetic member 32 are identical in structure and completely fill the inner cavity of the protruding structure 4, and when the radial cross section of the protruding structure 4 is a circular cross section, the first magnetic member 31 and the second magnetic member 32 are mirror-symmetric with respect to the radial direction of the circular cross section, so that the magnetization direction of the first magnetic member 31 and the magnetization direction of the second magnetic member 32 are mirror-symmetric with respect to the radial direction of the circular cross section on the premise that the materials and structures of the first magnetic member 31 and the second magnetic member 32 are identical.

When the radial cross section of the protruding structure 4 is an elliptical cross section, as shown in fig. 6 to 8, the first magnetic member 31 and the second magnetic member 32 are mirror-symmetric with respect to the minor axis direction of the elliptical cross section, so that the magnetization direction of the first magnetic member 31 and the magnetization direction of the second magnetic member 32 are mirror-symmetric with respect to the minor axis direction of the elliptical cross section on the premise that the materials and structures of the first magnetic member 31 and the second magnetic member 32 are the same.

The structure is convenient for improving the stability of the adsorption structure of the first belt body 1 and the second belt body 2 and improving the adsorption strength; referring to fig. 9, it is convenient for the protruding structures 4 of the first belt body 1 to extend into the space between the adjacent protruding structures 4 of the second belt body 2, and further reduce the gap between the first belt body 1 and the second belt body 2.

Usually, only one side of the strap has strong magnetism (suction side) and the other side has no magnetism or weak magnetism, which is more beneficial to enhance the user experience, and as an alternative embodiment, referring to fig. 7 and 8, the shielding members 5 are arranged in the protruding structures 4 of the first strap body 1 and the second strap body 2, and the shielding members 5 are fixed on the side opposite to the suction side. The shielding member 5 may be made of a magnetic conductive metal, and can increase the magnetic field intensity between the magnetic members and the magnetic field intensity on the adsorption side.

Above-mentioned magnetic component of this embodiment, the protruding structure 4 of the first area body 1 can stretch into between the adjacent protruding structure 4 of the second area body 2, and the protruding to concave dislocation of natural formation adsorbs, and it is more inseparable to laminate between two area bodies, improves adsorption strength, and two area bodies are difficult for separating, as shown in fig. 9.

Example two

The magnetic assembly with the above structure has the following problems that as shown in fig. 10, the first belt body 1 and the second belt body 2 are easy to be dislocated in the width direction, and the two belt bodies are difficult to be aligned in the width direction, that is, the positioning in the width direction has a poor centering effect, which affects the wearing feeling of the user. In actual products, however, it is desirable that the first tape body 1 and the second tape body 2 are well aligned in the width direction without significant deviation when worn.

In view of the above problems, the second embodiment is an improvement on the first embodiment, and is different from the first embodiment only in that:

referring to fig. 11-14, fig. 13 is a schematic structural view of the magnet unit in the first belt of the present invention, and fig. 14 is a schematic structural view of the magnet unit in the second belt of the present invention.

Four polarities are distributed on the same plane of the magnetic unit 3 along the width direction of the first belt body 1 or the second belt body 2, and the S pole and the N pole in the four polarities are arranged at intervals; in other words, in the present embodiment, a 4-pole magnetizing manner is used in each magnetic unit 3 along the width direction of the corresponding belt.

Specifically, referring to fig. 11 to 14, in the first belt body 1, four polarities, namely an N pole, an S pole, an N pole, and an S pole, are distributed on the same plane of the magnetic unit 3 along the width direction of the first belt body 1; in the second belt body 2, four polarities, namely an S pole, an N pole, an S pole and an N pole, are distributed on the same plane of the magnetic unit 3 along the width direction of the second belt body 2; the S pole and the N pole at the corresponding positions in the two belts are adsorbed and fixed.

Above-mentioned structure, when taking first area body 1 and second area body 2 to adsorb each other, when two area bodies have the dislocation in the width direction, because four polarity S utmost point and N interelectrode separate the arrangement in first area body 1, the second area body 2, produce simultaneously and return the normal force, can in time return under the repulsion of adjacent polarity, play the effect of rectifying.

As shown in fig. 11 and 12, the uppermost S pole of the second belt body 2 is used to adsorb with the uppermost N pole of the first belt body 1, when there is a deviation in the width direction of the two belt bodies, such as the uppermost S pole of the second belt body 2 is dislocated to the S pole close to the first belt body 1, due to the repulsion, it can be timely aligned, and it is ensured that the first belt body 1 and the second belt body 2 can be aligned in the width direction.

It is verified that when eight and twelve polarities are distributed on the same plane of the magnetic unit 3 along the width direction of the first belt body 1 or the second belt body 2, the attraction force is reduced, and therefore, the magnetic unit 3 is most preferably magnetized by four poles.

EXAMPLE III

The embodiment provides a belt-mountable watch, which comprises the magnetic component. At this time, two wrist bands on the watch can be taken as the first band body 1 and the second band body 2 respectively, and the two wrist bands are fixed in an adsorption mode without buckles.
