A running board and a treadmill that realize the self-adjustment of the softness and hardness of the running board

Abstract

The invention discloses a running board and a treadmill capable of self-adjusting the softness and hardness of the running board, and belongs to the technical field of treadmill design. The invention includes a frame, a running board body and an air bag. The running board body is installed on the frame, the air bag is arranged on the frame, and the top of the air bag is against the running board body. It also includes a subsidence monitor and an infrared light emitting tube for monitoring the subsidence of the running board body. According to the monitoring data of the subsidence monitor, the airbag is charged / deflated to adjust the hardness of the running board body; wherein, the lower The sinking monitor has a shutter and a row of infrared light receiving tubes, and the shutter follows the running board body up and down between the row of infrared light receiving tubes and the infrared light emitting tubes along the arrangement direction of the infrared light receiving tubes. The invention monitors the light of the infrared light emitting tubes placed under the running board through the infrared light receiving tubes arranged in a row, replaces the precise sensing element, monitors the sinking of the running board in real time, and automatically inflates and deflates the airbag.

Description

technical field [0001] The invention belongs to the technical field of treadmill design, and in particular relates to a treadmill and a treadmill which realize the self-adjustment of the softness and hardness of the treadmill. Background technique [0002] The running board of traditional treadmills has poor shock absorption and buffering effect. When using it, it is easy to cause a large impact on the runner's joints, which may easily cause joint fatigue and even joint damage. In order to improve the shock absorption of the running board Cushioning effect. At present, there are some cushioning structure designs suitable for running boards on the market, that is, adding a shock-absorbing structure to the bottom of the running board of the treadmill, but most of the shock-absorbing structures are adjusted by the runner's own choice of shock-absorbing mode Shock-absorbing strength, the shock-absorbing effect of this kind of shock-absorbing method is limited.

Problems solved by technology

[0002] The running board of traditional treadmills has poor shock absorption and buffering effect. When using it, it is easy to cause a large impact on the runner's joints, which may easily cause joint fatigue and even joint damage. In order to improve the shock absorption of the running board Cushioning effect. At present, there are some cushioning structure designs suitable for running boards on the market, that is, adding a shock-absorbing structure to the bottom of the running board of the treadmill, but most of the shock-absorbing structures are adjusted by the runner's own choice of shock-absorbing mode Shock-absorbing strength, the shock-absorbing effect of this kind of shock-absorbing method is limited

[0003] Specifically, runners of different weights have different elastic deformation pressures on the shock-absorbing components, resulting in completely different shock-absorbing effects of the same mode of shock-absorbing strength on runners of different weights, and inappropriate shock-absorbing strength will directly injure the runner's knee

[0004] The prior art CN109350909B provides a shock-absorbing treadmill, which can automatically control the anti-pressure capacity of the treadmill according to the user's weight, but the way the shock-absorbing treadmill obtains the user's weight is by setting a pressure sensor, and then Using a tablet computer to calculate based on body weight, this kind of shock-absorbing treadmill relies on pressure sensors and tablet computers. First, there is the problem of high cost of the treadmill. Second, pressure sensors and tablet computers are high-precision components, especially pressure sensors. The sensor is easy to cause inaccuracy after long-term use. Three, this method only considers the weight of the runner, so the shock absorption adjustment effect is still limited. Running is a dynamic process, and the sinking range of the running board during running is not constant Depends entirely on the runner's weight

[0005] In addition, the application publication number CN111840899A discloses a treadmill with an airbag in a new treadmill airbag shock-absorbing structure, and specifically discloses an airbag inflation and deflation matching device. By detecting the internal pressure of the airbag and It shows that the user can inflate and deflate the airbag by controlling the pump and deflation valve through the key switch, so as to control the hardness of the running board. Although the control method is controlled during the use of the treadmill, the running The hardness of the board is still manually controlled, that is, the hardness of the running board is affected by the user's subjective feelings, and it is only adjusted according to the human body's feelings. This method of use is not scientific.

[0006] All in all, the current running board cannot adjust the shock absorption effect well according to the sinking range of the running board, which leads to poor performance of the running board when used for runners of different weights, and it is easy to bring unnecessary inconvenience to the runners. bodily injury
