Description

Sports equipment magnetic control damping device

The present invention relates to a magnetron damping device for sports equipment, in particular to an inventor of an innovative structure that can be used alone or in parallel with other rotating damping devices.

Due to the change in lifestyle, more and more people have difficulty moving out of the outdoors, let alone regular outdoor exercise habits. Therefore, the relevant industry began to launch a variety of sports equipment, so that users can enjoy the sports and fitness at any time without being restricted by the weather and time at home. In order to improve the user's exercise efficiency, the sports equipment seen in the workshop will be matched with the flywheel and the damping, which is the load that the user uses when moving, so that it can achieve the same fitness effect in a short time, to meet the requirements of modern people. The need for efficient fast foodism.

The common damping device can be roughly divided into two types: direct contact and non-contact type. The direct contact is not due to the technical field of the present creation, and therefore will not be described again. Non-contact type usually adopts the method of magnetic control to change the area of magnetic induction between the magnet and the flywheel to achieve the purpose of adjusting the damping effect. The existing magnetron damping device usually uses a magnet to act on the side of the flywheel or the periphery of the flywheel. However, whether it is the side of the flywheel or the periphery of the flywheel, the magnets are used to move axially relative to the flywheel. To change the magnetic induction or magnetic induction area, so as to achieve the purpose of changing the amount of damping provided. However, the flywheel itself has a certain thickness, and it is necessary to reserve the space for the left and right movement of the magnet on at least one side thereof. The invisible space expands the volume of the sports equipment, and relatively increases the storage and transportation cost of the sports equipment.

Therefore, in view of the problems existing in the above-mentioned conventional structure, how to develop an innovative structure that is more ideal and practical, is expected by users, and is also related to the industry's efforts to develop breakthrough goals and directions.

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

The main purpose of this creation is to provide a magnetic control damping device for sports equipment, and the technical problem to be solved is to develop a new type that is more ideal and practical, can be used alone, or with other rotary damping. The structural type of devices used in parallel is an innovative breakthrough for the goal.

The technical feature of the present invention is mainly that the magnetic control damping device of the sports equipment comprises a turntable for concentrically fixing on the rotating structure of the sports equipment, and a spindle fixed to the rotating structure.
