Description

Technical Field

[0001] The present invention relates to a fitness equipment, in particular to a dynamic rowing machine capable of simulating rowing motion. Background Art

[0002] A rowing machine, also called a rowing ergometer, is a fitness equipment that simulates rowing motion and has a good effect on strengthening the muscles of the legs, waist, upper limbs, chest, and back. Rowing machine exercise is a smooth, interesting and self-challenging fitness exercise. Each time you row, the upper limbs, lower limbs, waist and abdomen, and back will complete a complete contraction and extension during the process, achieving a full-body muscle exercise effect. Especially for people with more fat in the waist and abdomen and upper arms, the rowing machine exercise can bring unexpected body shaping effects. The rowing machines of the prior art usually include components such as a base, a sliding seat, foot pedals, and a movement mechanism. The base is usually placed on the ground or a flat surface and is immovable. A slide rail is provided on the base, and the sliding seat is slidably configured on the slide rail of the base. The foot pedals are fixed on the base and are in a suitable position relative to the sliding seat. A resistance component is installed in the movement mechanism to provide resistance during rowing motion. When the operator imitates the rowing action, the operator drives the resistance component in the movement mechanism through a pulling component or a rowing rod component, and uses the feet to step on the foot pedals, so that the sliding seat moves back and forth on the slide rail of the base, forming the effect of imitating rowing. However, for this kind of rowing machine in the prior art, since the base does not move, the feeling of the boat moving is lacking, and moreover, there is also a lack of resistance when the sliding seat slides on the slide rail, thus affecting the rowing experience. To solve this problem, a rowing machine in the prior art is equipped with rollers at the bottom of the base, and the sliding seat and the base are connected by chain drive, so that when the sliding seat moves back and forth, it can drive the base to move back and forth, forming the feeling of the boat moving. However, this kind of rowing machine in the prior art still has the following drawbacks: First, the movement of the sliding seat and the movement of the rollers of the base will be asynchronous. This is because the rollers and the frame are not integral. When the rollers slip, the relative position with the sliding seat will change, causing the overall displacement of the frame. Second, the transmission mechanism has a complex structure, which causes inconvenience in both installation and use. Third, the manufacturing cost is high, and it is difficult to achieve industrial production. Summary of the Invention
