Running board hardness self-adjusting method applied to running board and application

Abstract

The invention discloses a running board hardness self-adjusting method applied to a running board and an application, and relates to the technical field of running machines. The method comprises the following steps: receiving level signals of a column of infrared light receiving tubes, obtaining sinking amplitude data of a running board body according to the change of the level signals, obtaining an actual sinking amplitude value according to the sinking amplitude data of the running board body, and comparing the actual sinking amplitude value with a body sinking amplitude value; if the actual sinking amplitude value is larger than a preset sinking amplitude value, enabling the inflation and deflation equipment o pressurize the air bag to increase the hardness of the running board body; and if the actual sinking amplitude value of the running board body is smaller than the preset sinking amplitude value, enabling the inflation and deflation equipment to decompress the air bag to reduce the hardness of the running board body. The infrared light receiving tubes arranged in columns are used for monitoring light rays of the infrared light emitting tubes arranged below the running board, precise sensing elements are replaced, and real-time monitoring is carried out on sinking of the running board.

[0002] The running board of the traditional treadmill has poor shock absorption and buffering effect, and it is easy to cause a large impact on the runner's joints during use, which may easily cause joint fatigue of the runner, and even cause the safety risk of joint damage. There are also 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 runners independently selecting the 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 Use a tablet computer to calculate the degree of shock absorption based on body weight and pressure. This shock-absorbing treadmill relies on a pressure sensor and a tablet computer. First, there is a problem of high cost of the treadmill. Second, the pressure sensor and tablet computer are both high-precision Components, especially the pressure sensor, can easily lead to inaccuracy after long-term use. Among the three, this method only considers the weight of the runner, which is a single factor that affects the shock absorption adjustment effect. It is still limited. Running is a dynamic process. Running The sinking of the running board during the process is not entirely dependent 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 After that, the user can control the pump and the deflation valve to inflate and deflate the airbag through the button switch, so as to control the hardness of the running board. The pressure monitoring is also used to adjust the hardness of the running board. After a period of use, there will be a problem of reduced accuracy, especially when it is used on products such as treadmills that require continuous monitoring, the wear and tear of the pressure sensor is even more prominent

[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
