Description

Electromagnet air gap limit adjustment device structure (1)

The present invention relates to an electromagnet device applied to a flywheel, and more particularly to an electromagnet air gap limit adjusting device structure (1).

According to an electromagnet device applied to a flywheel, as shown in FIGS. 6 and 7, a support base 40, a flywheel 50, a rotor, a stator and a magnetic control unit 60 are included, wherein the flywheel The 50 series is generally a concave circular disk-shaped body, and is rotatably disposed on the support base 40. The rotor has a rotating shaft and at least one magnet unit, and the rotating shaft is rotatably disposed at the center of the flywheel 50. a position in which the at least one magnet unit is disposed at a concave side of the flywheel 50, and the stator is fixed on the support base 40 and is nested with the rotor. The stator includes a plurality of a first magnetic pole and a plurality of second magnetic poles, each of the first and second magnetic poles are arranged and staggered with each other, each of the first and second magnetic poles is wound with a coil, and each of the first magnetic poles is greater than each of the second magnetic poles The magnetic poles and the magnetron 60 are mounted on the side of the support base 40 adjacent to the edge of the flywheel 50, and can be magnetized by the current generated by each coil to change the load of the flywheel 50; As mentioned above, when the user When the wheel equipment performs the exercise, the resistance required for the pedaling is the eddy current formed by the rotation of the rotor inside the flywheel 50 around the stator, so that the magnetron 60 generates a magnetic force, and thus has a magnetic resistance to provide the flywheel 50. Load resistance, the effect of pedaling exercise.

However, it is not difficult to find out that the above-mentioned conventional structure has some shortcomings. The main reason is as follows: eddy current is generated when the flywheel 50 is stepped on, and the magnetic control unit 60 is provided to generate magnetic resistance, so that the magnetic control unit The 60 series generates magnetic force through the eddy current for a long time, and at the same time, a high heat temperature is generated, so that the support base 40 for fixing the magnetron unit 60 is easily softened and deformed by heat conduction, so that the magnetron unit 60 cannot be effectively positioned, thereby affecting the magnetron unit. 60 and the flywheel 50 form a proper gap of magnetic resistance. In severe cases, the magnetic control unit 60 directly attracts the end edge of the flywheel 50, which not only fails to provide an effective motion effect, but also causes sportsman injuries and sports equipment. The damaged person is actually the missing one in the structure.

In view of this, the creator has been engaged in the manufacturing development and design experience of related products for many years. After detailed design and careful evaluation, the author has finally achieved a practical and practical creation.

The technical problem that this creative is to solve is to provide the above-mentioned shortcomings in the prior art. The structure (1) of an electromagnet air gap limit adjusting device comprises: a support base, a flywheel and a magnetic control unit, wherein the support base has two parallel support plates, and the two support plates are integrally extended with one The connecting plate has a connecting portion protruding outwardly, and a limiting bracket is disposed on the outer side of the two connecting plates. The flywheel is generally formed in a circular disk shape and is rotatably disposed. Between the two support plates of the support base, and the electromagnetic wheel between the flywheel and the support base, the current is generated when the flywheel rotates. The magnetic control unit is accommodated between the two connecting plates of the support base and penetrates through the four screws. The two connecting plates are combined and fixed, wherein the two screws are connected at the same time through the limit brackets on the outer side of the two connecting plates, and finally the two links are respectively used by a connecting piece. The limiting bracket and the connecting portion on the outer side of the connecting plate are combined and positioned, thereby mounting the magnetic control unit adjacent to the edge of the flywheel, and forming a magnetic force by the current generated by the electromagnetic unit, so that the load of the rotating wheel changes, and by the above structure,俾 to constitute an electromagnet system limit adjustment device structure (1).

Compared with the effect of the prior art: the magnetic control unit of the present invention is mounted on the support base by the four-screw, wherein the two screws are connected together through the limit brackets on the outer side of the two connecting plates, and finally the two are respectively connected through a connecting piece. The position bracket is locked with the connection portion of the same side connecting plate, thereby additionally providing the strength of the magnetic control unit and the support base, ensuring the position of the magnetic control unit on the support base, and avoiding the magnetic control unit and the flywheel gradually shortening the distance, and Losing the original magnetoresistance effect, therefore, not only can reduce the damage rate of sports equipment, but also can improve the service life of the equipment and the user's exercise effect.

In order to enable your review committee to have a better understanding and understanding of the purpose, characteristics and efficacy of this creation, please refer to the following [Simplified Description of the Drawings] for details: First, please refer to the first and second figures, an electromagnet air gap limit adjusting device structure (1), comprising: a support base 10, a flywheel 20 and a magnetic control unit 30, wherein the support base The support plate 11 has two parallel support plates 11 , and the two support plates 11 are integrally extended with a connecting plate 12 . The two connecting plates 12 are outwardly provided with a connecting portion 121 , and the connecting portion 121 is parallel to the outside of the two connecting plates 12 . A limiting bracket 13 is disposed, and the connecting portion 121 of the two connecting plates 12 is provided with a screwing hole 122, and the two limiting brackets 13 are respectively provided with a locking portion 131 corresponding to the screwing hole 122 of the connecting portion 121.
