Description

Technical Field

[0001] This utility model relates to the field of fitness equipment technology, and in particular to a bidirectional damping drive device. Background Technology

[0002] With the improvement of living standards, more and more people are exercising in pursuit of better physical fitness. This requires the use of fitness equipment, among which leg exercise machines are frequently used. While existing leg exercise machines can meet the needs, users are limited to a single leg movement of either outward expansion or inward contraction during exercise. They don't allow for free extension and contraction of the legs, making leg exercises inconvenient.

[0003] To address this problem, this utility model was developed. Utility Model Content

[0004] Therefore, in view of the above problems, this utility model proposes a bidirectional damping drive device with a simple structure and capable of bidirectional rotation.

The end of the abutment plate away from the rotating rod abuts against the inner wall of the swing frame after the rotating rod rotates counterclockwise.

[0009] A further improvement is that: the two ends of the abutting plate are provided with abutting wheels, and the abutting wheels abut against the inner wall of the fixed plate or the swing frame.

[0010] A further improvement is that the linkage device includes a linkage rod, one end of which is hinged to the swing rod, and the other end of which is connected to the damping device.

[0011] A further improvement is made to the damping device, which includes a sliding rod that slides through the frame. One end of the sliding rod is provided with a first connecting seat, which is connected to the linkage device. The other end of the sliding rod is provided with a second connecting seat, on which a damping spring is provided. The other end of the damping spring is connected to the frame.

[0021] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0022] refer to Figure 1-5 The present invention discloses a bidirectional damping drive device, comprising a frame 1 and a U-shaped fixed frame 2. The fixed frame 2 is fixedly disposed on the inner side of the frame 1. A rotating rod 4 is rotatably disposed on the fixed frame 2, and a swing frame 14 is rotatably disposed on the rotating rod 4. The swing frame 14 is located inside the fixed frame 2, and a swing rod 6 is hinged inside the swing frame 14. A connecting rod 7 is hinged to the swing rod 6. A sliding rod 9 is slidably disposed on the frame 1. One end of the sliding rod 9 is provided with a first connecting seat 8, which is hinged to the connecting rod 7. The other end of the sliding rod 9 is provided with a second connecting rod 7. The second connecting seat 10 is provided with a damping spring 11. The other end of the damping spring 11 is connected to the frame 1. The fixed frame 2 is provided with a stop plate 12 that can drive the swing rod 6 to swing when the rotating rod 4 rotates clockwise or counterclockwise. The stop plate 12 is fixed on the rotating rod 4. A clockwise swinging device is provided between the stop plate 12 and the swing plate, which drives the swing rod 6 to swing when the rotating rod 4 rotates clockwise. A counterclockwise swinging device is also provided between the stop plate 12 and the swing plate, which drives the swing rod 6 to swing in a single direction when the rotating rod 4 rotates counterclockwise.

[0023] Specifically, the swing device includes a hinge sleeve 15, which is hinged to the swing frame 14. The swing rod 6 is fixedly mounted on the hinge sleeve 15. A fixing plate 16 is provided on the hinge sleeve 15. The end of the abutment piece 12 away from the rotating rod 4 abuts against the fixing plate 16 after the rotating rod 4 rotates clockwise.

[0024] Specifically, the reverse swing device is as follows: the swing frame 14 has a cross section 142 tangent to the fixed frame 2 at the other end of the hinge sleeve 15, and a swing arc 141 is provided on the upper end of the cross section 142 of the swing frame 14 so that the swing frame 14 can swing counterclockwise. The end of the abutment plate 12 away from the rotating rod 4 abuts against the inner wall of the swing frame 14 after the rotating rod 4 rotates counterclockwise.

[0025] In order to enable the abutment plate 12 to better abut against the fixed plate 16 and the swing frame 14, thereby better pushing the fixed plate 16 and the swing frame 14, the abutment plate 12 is provided with abutment wheels 13 at both ends, and the abutment wheels 13 abut against the inner wall of the fixed plate 16 or the swing frame 14.

[0026] In order to facilitate the rotation of the rotating rod 4, a drive plate 3 is also included. One end of the drive plate 3 is fixedly sleeved on the rotating rod 4, and the other end of the drive plate 3 is connected to the transmission component of the fitness equipment.

[0027] To facilitate the installation of the rotating rod 4, multiple connecting discs 5 are also included. The rotating rod 4 is rotatably mounted on the connecting discs 5 via bearings. The fixed frame 2 and the swing frame 14 are provided with clearance openings for the rotating rod 4 to pass through. The connecting discs 5 are bolted to the fixed frame 2 or the swing frame 14.

[0028] Working principle:

[0029] When the user's legs expand outward, the rotating rod 4 rotates clockwise, causing the abutment plate 12 to rotate clockwise. The abutment wheel 13 on the abutment plate 12 abuts against the fixed plate 16, thus pushing the fixed plate 16 to swing. The fixed plate 16 drives the hinge sleeve 15 to rotate, which in turn drives the swing rod 6 to swing. The swing rod 6 drives the connecting rod 7 to swing, causing the sliding rod 9 to slide. After the sliding rod 9 slides, it pulls the damping spring 11, thus achieving the exercise of expanding the legs outward. When the user's legs contract inward, the rotating rod 4 rotates counterclockwise, causing the abutment plate 12 to rotate counterclockwise. The abutment wheel 13 on the abutment plate 12 abuts against the swing frame 14, causing the swing frame 14 to rotate. The swing frame 14 rotates, causing the swing rod 6 connected to the swing frame 14 to swing. Then, the swing rod 6 drives the connecting rod 7 to swing, which in turn drives the sliding rod 9 to slide. The sliding rod 9 pulls the damping spring 11, thus achieving the exercise of contracting the legs inward. This allows fitness enthusiasts to perform both inward and outward expansion movements. This makes it much more convenient for them to choose their workout routine at any time. Furthermore, when the rotating rod 4 rotates clockwise, the cross-section 142 on the swing frame 14 abuts against the fixed frame 2, preventing the swing frame 14 from moving and allowing the abutment plate 12 to better push the swing rod 6 to swing.
