Description

Electromagnet air gap limit adjustment device structure

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

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 to be solved by the present invention is to provide an electromagnet air gap limit adjusting device structure in view of the above-mentioned shortcomings existing in the prior art.

The structure of an electromagnet air gap limit adjusting device comprises: a support base, a flywheel and a magnetic control unit, wherein a support base has two symmetrical support plates and supports two supports on one side of the support base The plate is fixed with a positioning rod, and a flywheel is generally formed into a circular disc-shaped body, and is rotatably disposed between the two supporting plates of the supporting seat, and the electromagnetic wheel is further arranged between the flying wheel and the supporting base, and then the flywheel is rotated. When a current is generated, a magnetic control unit is mounted on one side of the support bracket on both sides, and the two joint brackets each have a connecting hole, and the two connecting members are connected through the positioning rod and the connecting bracket. Thereby, the magnetron unit is installed adjacent to the edge of the flywheel, and the magnetic force generated by the electromagnetic unit can form a magnetic force, so that the load of the flywheel is changed, According to the above structure, the structure of the electromagnet air gap limit adjusting device is constructed.

Compared with the effect of the prior art: the magnetic control unit of the present invention is connected with the positioning rod of the support base through the two joint brackets, additionally providing the strength of the connection between the magnetron unit and the support base, and indeed using the positioning rod to abut the support of the support base. The end of the plate reaches the limit state, avoiding the magnetic control unit and the flywheel gradually shortening the distance, and losing the original magnetoresistance effect, preventing the damage of the sports equipment, greatly improving 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, comprising: a support base 10, a flywheel 20 and a magnetic control unit 30, wherein a support base 10 has two The support plate 11 is symmetrical, and a positioning frame 12 is fixed across the two supporting plates 11 on one side of the support base 10. The flywheel 20 is generally a circular disk-shaped body and is rotatably disposed on the support. Block 10 bis support There is an electromagnetic unit (not shown) between the flywheel 20 and the support base 10, and an electric current is generated when the flywheel 20 rotates. A magnetic control unit 30 is mounted on both sides with a connecting bracket 31. The two connecting brackets 31 each have a connecting hole 311, and the two connecting members 312 are disposed to be coupled with the connecting bracket 31 through the positioning frame 12, thereby mounting the magnetic control unit 30 adjacent to the edge of the flywheel 20, and The magnetic force generated by the electromagnetic unit can form a magnetic force, and the load of the flywheel 20 is changed.
