A four-stage buffer structure for a treadmill running board

Abstract

The invention discloses a running plate four-stage buffering structure for a running machine, which comprises a frame and a running plate arranged on the frame, wherein a positioning cushion is arranged at the back end of the running plate; three-stage buffering assemblies and a fourth-stage buffering structure are further independently arranged in the middle of the running plate; the fourth-stage buffering structure is movably mounted between the frame and the running plate. According to the invention, the positioning cushion is arranged at one end of the running plate to enable the running plate to form a cantilever structure, so that the own elastic force of the running plate is fully utilized; as the three-stage buffering assemblies and the fourth-stage buffering structure are arranged, when force is applied to the running plate, weight of great load can be borne and the effect that the buffering action is uniform and slow in stress can be achieved under the multi-stage buffering action of the three-stage buffering assemblies, at the same time, the position of the fourth buffering structure is adjusted to change the origin of force of the running plate and further change the buffering deflection of the running plate. Therefore, the running plate four-stage buffering structure can meet the requirements of different crowds and different motions, and achieves the effects that the buffering performance and shock-absorbing performance are excellent, the recoil force is small, and the motion is comfortable.

Description

technical field [0001] The invention relates to the field of treadmills, in particular to a four-stage buffer structure of a running board of a treadmill with good shock absorption and buffering effect and comfortable exercise. Background technique [0002] In order to reduce the impact of the treadmill on the human body and increase the comfort of running, the general treadmill is designed with a running board buffer device. The common practice is to install a certain elastic buffer pad between the frame and the running board. , because the maximum safety load of the treadmill must be met, the elasticity and elasticity of the cushion are designed according to the maximum load weight of the treadmill, so the cushion must have greater strength and hardness, making it difficult for the treadmill to achieve a good Cushioning effect, and different groups of people have different requirements for cushioning and shock absorption during different exercise states. At the same time, ...

[0002] In order to reduce the impact of the treadmill on the human body and increase the comfort of running, the general treadmill is designed with a running board buffer device. The common practice is to install a certain elastic buffer pad between the frame and the running board. , because the maximum safety load of the treadmill must be met, the elasticity and elasticity of the cushion pad are designed according to the maximum load weight of the treadmill, so the cushion pad must have greater strength and hardness, making it difficult for the treadmill to achieve a good performance during use. Cushioning effect, and different groups of people have different requirements for cushioning and shock absorption in different exercise states. At the same time, the elastic cushioning device has no levels of elastic cushioning, and the elastic mutation is large. The resulting counter-impact force makes the runner feel uncomfortable.

At present, there is no treadmill cushioning that can meet the requirements of different groups of people and different exercise states for cushioning effect and sports comfort. The cushioning effect is very good under various conditions, the cushioning force is uniform and layered, and the recoil force is small. structure
