Preferably, the lower surface of the support portion 61 is hinged to the link assembly 62, which has the advantage that when the link assembly 62 rotates along with the rotating shaft 51, the support portion 61 at the upper end of the link assembly 62 is inclined by the rotation of the link assembly 62, so that the upper surface of the support portion 61 and the lower surface of the running board 20 cannot be parallel to each other; and the supporting part 61 can be rotated by an angle in a hinged manner to keep a state of being parallel to the lower surface of the running board 20, so as to better support and buffer the running board 20.

This kind of mode of setting up can provide the support in the left and right sides of running board 20 simultaneously, makes the dynamics of supporting stronger, and the supporting effect is more even and stable, and does not influence the elastic deformation of running board 20 middle part. Of course, only one set of the executing components may be provided, and the executing components are supported by the middle part of the running board 20; or, the executive component can be set as four, eight or more groups, and is uniformly arranged below the running board 20 to support a plurality of parts of the running board 20 at the same time, so as to adjust the deformation amplitude of the running board 20.

Further, as shown in fig. 4 and 5, in order to optimize the transmission effect between the power element and the rotating shaft 51 and enable the rotating shaft 51 to bear larger load capacity, two couplings 53 are respectively arranged on two sides of the motor 52, and simultaneously, one coupling 53 is also respectively arranged at a position close to two groups of actuating components.

As shown in fig. 1 and 2, the control assembly 90 is disposed at the front of the treadmill and is fixedly disposed on the base 10 of the treadmill, and the sensor transmits the deformation amount of the running board 20 monitored in real time to the control assembly 90, which is determined by the control assembly 90 and issues a control command to make the power element and the executing assembly perform corresponding actions to adjust the deformation amplitude of the running board 20.

Because the user runs on the running board 20, the front and back positions of the body may be changed, and the front and back positions of the execution assembly are adjusted, so that the supporting position can accurately correspond to the stressed position of the running board 20, and the adjustment effect of the execution assembly is further improved.

Furthermore, the running board adjusting mechanism can automatically adjust the elasticity of the running board according to preset data, and can switch the elasticity mode of the running board through a remote controller according to personal preference of a user so as to meet the individual requirements of the user. In addition, the running board adjusting mechanism in the utility model can also be manually adjusted, namely the positions and the heights of the supporting part and the elastic buffer part are manually adjusted so as to change the elasticity of the running board.

As shown in fig. 9, the present invention also discloses an automatic adjustment method for a running board, which is applied to the above-mentioned running board adjustment mechanism, and is described in detail below with reference to the accompanying drawings.

The automatic adjustment method of the running board comprises the following steps:

(1) and starting up and powering on to start the running machine or the walking machine and restore to the initialization state.

(2) When the user starts to move, the sensing assembly 80 monitors the deformation of the running board 20 in real time, i.e. the distance between the lower surface of the running board 20 and the machine body base 10.

(3) The sensing component 80 transmits the data signal to the control component 90, and the control component 90 performs calculation and analysis on the data signal to determine whether the deformation amount of the running board 20 is equal to a preset value.

(4) When the deformation of the running board 20 is equal to the preset value, the control component 90 controls the execution component not to act; when the deformation of the running board 20 is not equal to the predetermined value, the control unit 90 controls the operation of the executing unit so that the executing unit moves closer to or away from the running board 20.

Specifically, if the deformation amount of the running board 20 is smaller than the preset value, which means that the deformation amplitude of the running board 20 is too small and the elasticity and the buffering are insufficient, the control component 90 controls the execution component to move down to reduce the supporting force on the running board 20, or increase the interval gap between the execution component and the lower surface of the running board 20, so that the running board 20 has a larger deformation space and the deformation amplitude of the running board 20 is increased; if run board 20 deformation volume and be greater than the default numerical value, represent that run board 20 deformation range is too big, and the supporting effect is not enough, then control assembly 90 control executive component shifts up, and the increase is to the support dynamics of running board 20, or makes the interval clearance between executive component and the running board 20 lower surface reduce to the deformation space that makes run board 20 reduces, and then reduces the deformation range of running board 20. The control unit 90 controls the specific magnitude of the upward or downward movement of the actuator according to the absolute value of the difference between the deformation of the running board 20 and the predetermined value.

(5) In the step (4), after the control component 90 controls the action of the execution component to enable the execution component to approach or leave the running board 20, the step (2), the step (3) and the step (4) are repeated and circularly performed until the deformation amount of the running board 20 is equal to a preset value, the running board 20 is adjusted to be proper in elasticity and buffer degree, and the control component 90 controls the execution component to stop acting.

(6) In the step (3), after the control assembly 90 judges that the deformation amount of the running board 20 is not equal to the preset value, the control assembly 90 judges again to judge whether a manual regulation record exists;

if the manual adjustment record exists, the deformation amplitude of the running board 20 is automatically adjusted according to the habit or the preference of the user, and the control component 90 controls the execution component not to act;

if no manual adjustment is recorded, the process proceeds to step (4), and the control unit 90 controls the action of the executing unit to move the executing unit closer to or away from the running board 20 until the deformation amount of the running board 20 is equal to the preset value.

The utility model also discloses a treadmill, which comprises the running board adjusting mechanism or comprises the running board automatic adjusting method.
