Description

Technical Field

[0001] The utility model relates to aerobic fitness equipment, in particular to a resistance device installed on aerobic fitness equipment. Background Art

[0002] In aerobic fitness equipment such as exercise bikes and ski machines, in order to achieve the purpose of adjusting the fitness intensity, a resistance adjustment component is usually equipped in the resistance device. According to different resistance sources, there are wind resistance, magnetic resistance or wind-magnetic dual-resistance resistance devices. Among them, the wind-magnetic dual-resistance resistance device means that there are two resistance forms of wind resistance and magnetic resistance in the device at the same time. In the prior art, the adjustment components of the wind-magnetic dual-resistance resistance device include a wind resistance adjustment component and a magnetic resistance adjustment component, that is, it is necessary to separately adjust the wind resistance or the magnetic resistance size, which has a relatively high requirement for the proficiency of the exerciser. Although there has appeared an adjustment device that can adjust the wind-magnetic dual resistance at the same time on the market, this device has a complex structure and a large self-weight, thus affecting the adjustment range of the resistance. Content of the Utility Model

[0003] The purpose of the utility model is to overcome the shortcomings existing in the prior art, and provide a resistance device for fitness equipment that can adjust the wind-magnetic dual resistance at the same time, and has a simple structure and a large adjustment range. The technical scheme adopted is: a resistance device for fitness equipment, including a wind resistance part, a magnetic resistance part and a resistance adjustment part. The wind resistance part includes a wind wheel and a wind disk, and the magnetic resistance part includes a magnetic seat and a metal ring plate. It is characterized in that: the wind disk includes a wind disk I and a wind disk II that rotate relative to each other and cooperate to form a resistance adjustment area. The wind disk I is located on one side of the wind disk II, and the magnetic seat is located on the other side of the wind disk II; the wind wheel is fixedly connected to the housing, and the housing and the wind disk II are connected as a whole through a connecting piece. The metal ring plate is located between the wind disk II and the housing, and a rotating shaft is provided at the center of rotation of the wind wheel; the resistance adjustment part includes a magnetic seat adjustment track II provided on the wind disk II, and the adjustment rod passes through the wind disk I and is connected to the magnetic seat through the magnetic seat adjustment track II on the wind disk II; the distance between the point on the magnetic seat adjustment track II and the rotation center line where the center of rotation of the wind wheel is located is a variable value. When adjustment is required, rotate the wind disk I, and the adjustment rod drives the magnetic seat to move, thereby changing the relative position of the magnetic seat in the magnetic seat adjustment track II. After such adjustment, first, the air intake volume of the resistance adjustment area formed by the cooperation of the wind disk I and the wind disk II is changed, and the wind resistance value is changed. Second, the adjustment of the magnetic seat position changes the magnetic resistance value between the magnetic seat and the metal ring plate. In summary, the purpose of adjusting the wind-magnetic dual resistance at the same time is achieved.

[0004] The technical scheme of the utility model also includes: a magnetic seat adjustment track I corresponding to the position of the magnetic seat adjustment track II is provided on the wind disk I. The magnetic seat adjustment tracks on the wind disk I and the wind disk II have the same shape and position, which is convenient for the stable adjustment and movement of the magnetic seat position driven by the adjustment rod, so as to have a better adjustment effect.

[0005] The technical solution of the present utility model further includes: the resistance adjustment area includes the air inlet grille I and the wind deflector I on the air disc I, and the air inlet grille II and the wind deflector II on the air disc II. When the overlapping area between the air inlet grille II and the air inlet grille I is the largest, the air volume transported to the wind wheel through the air inlet grille is the smallest at this time, corresponding to the maximum wind resistance value; when the overlapping area between the air inlet grille II and the air inlet grille I is the smallest, the air volume transported to the wind wheel is the largest at this time, corresponding to the minimum wind resistance value. Therefore, by rotating the air disc I and changing the relative positions of the air disc I and the air disc II, the magnitude of the wind resistance value can be adjusted. Also, by rotating the air disc I, the relative positions between the magnetic seat and the metal ring can be changed simultaneously. When the distance between the magnetic seat and the metal ring increases, the magnetic resistance value increases; when the distance between the magnetic seat and the metal ring decreases, the magnetic resistance value decreases. For the above reasons, by rotating the air disc I, the magnitudes of both the wind resistance and the magnetic resistance can be adjusted simultaneously at one time.

[0006] The technical solution of the present utility model further includes: the resistance device further includes a gear position indication part, and the gear position indication part includes a gear position pointer on the air disc I and a gear position indication area on the air disc II. Considering that the diameter of the air disc II is usually larger than that of the air disc I, it is more suitable to set the gear position indication area on the air disc II. By rotating the air disc I, the corresponding gear position can be visually observed through the gear position pointer, and then the corresponding resistance value information can be obtained.

[0007] The technical solution of the present utility model further includes: both the air disc I and the air disc II are provided with central holes, and a short shaft and / or a cover are connected through the central holes.

[0008] The technical solution of the present utility model further includes: a magnetic buckle is installed on the magnetic seat. The magnetic buckle here is a relatively general term, referring to a functional component that has magnetism itself and generates magnetic resistance after approaching a metal material, and its shape is not limited to a disc shape. Due to the installation of the magnetic buckle on the base, a magnetic resistance is generated between the base and the metal ring, and the base is called the magnetic seat in this patent.

[0009] The technical solution of the present utility model further includes: the magnetic resistance part further includes a tension spring connected to the magnetic seat. Considering the requirement for the consistency of the magnetic seat position after repeated adjustment and the convenience of resetting, a tension spring is provided and connected to the magnetic seat.

[0010] The technical solution of the present utility model further includes: a fastener I is provided at the edge of the housing, and a fastener II is provided at the edge of the air disc II. The fastener I and the fastener II form a connecting member for connecting the housing and the air disc II. After being connected by the connecting member, the resistance device becomes an independent integral structure, and it can be connected to fitness equipment such as exercise bikes, rowing machines, and skiing machines.

[0011] The technical solution of the present utility model further includes: the wind wheel includes a wind wheel bottom ring and a wind wheel upper ring, as well as wind wheel fins connected between the wind wheel bottom ring and the wind wheel upper ring. The wind wheel further includes a bottom sheet, the wind wheel bottom ring is connected to the bottom sheet, and the bottom sheet is connected to the housing. The shape, quantity, and height settings of the wind wheel fins can all affect the resistance value of this resistance device. Therefore, different wind wheel fins can achieve different resistance value ranges.

[0012] The beneficial effects of the present utility model are as follows: The rotation gear pointer of this resistance device can simultaneously adjust the wind resistance and magnetic resistance, with convenient and rapid adjustment; this resistance device has a simple structure and a light self-weight, thereby providing a larger adjustment range for the resistance value.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] The following will describe the detailed embodiments of the present utility model in conjunction with the accompanying drawings.

[0016] The present utility model discloses a resistance device for fitness equipment, which includes a wind resistance part, a magnetic resistance part, a resistance adjustment part 4, and a gear indication part.

[0017] The wind resistance part includes a wind wheel 6 and a wind disk. The wind disk includes a wind disk I 2 and a wind disk II 3 that rotate relative to each other and cooperate to form a resistance adjustment area. The wind disk I 2 is provided with an air inlet grille I 21 and a wind deflector I 22, and the wind disk II 3 is provided with an air inlet grille II 31 and a wind deflector II 32. The wind disk I 2 and the wind disk II 3 cooperate to form a resistance adjustment area. By changing the relative position between the two wind disks, that is, correspondingly changing the shielding relationship between the air inlet grille of one wind disk and the wind deflector of the other wind disk, the adjustment of the air intake volume can be realized, and further the adjustment of the resistance value during the rotation of the wind wheel can be realized.

[0018] The magnetic resistance part includes a magnetic base 41 and a metal ring 10. A magnetic buckle is installed on the magnetic base 41, and a tension spring 43 is connected to the magnetic base 41. The relative position between the magnetic base 41 and the metal ring 10 is adjusted by the resistance adjustment part 4 to change the magnitude of the magnetic resistance.

In this way, driven by the adjustment rod 42, the position of the magnetic seat 41 changes, and the distance between the metal ring piece 10 and the magnetic seat 41 changes. It is well known that the distance between the metal ring piece and the magnetic seat 41 is inversely proportional to the magnitude of the magnetic force value. Therefore, by changing the distance between the magnetic seat 41 and the metal ring piece 10, the magnitude of the magnetic resistance can be adjusted.
