[0042] In another preferred embodiment of the present invention, the guide rails 30 may be provided in two, both ends of the first sensor bracket 61 are mounted on one side of the two guide rails 30, both ends of the second sensor bracket 62 are mounted on the other side of the two guide rails 30, and the arc-shaped bottom plate 12 is provided between the first sensor bracket 61 and the second sensor bracket 62 to form a seat cavity for the rower to place his feet and part of his body.

[0043] The back side of the bottom plate of the first fixed bracket 51 is provided with a plane, which is parallel to the first contact surface 611. The plane is used to press against the pressure sensor 70 on the first contact surface 611 to detect the force condition on the pedal 20. The bottom plate of the first fixed bracket 51 is also provided with a through hole. The first sensor bracket 61 is fixedly connected to a first limiting rod 6111, which passes through the through hole, and the diameter of the through hole is slightly larger than the diameter of the first limiting rod 6111. The free end of the first limiting rod 6111 is provided with a thread and a nut. The length of the middle section of the first limiting rod 6111 is larger than the thickness of the fixed plate of the sensor bracket 60, so that the fixed bracket 50 can maintain a certain length of forward and backward movement along the extension direction of the guide rail 30 under the condition of a certain degree of freedom. Therefore, when the front side of the pedal 20 is not subjected to force, the back side of the pedal 20 has no pressure on the pressure sensor 70. When a certain pressure exists on the front side of the pedal 20, the back side of the bottom plate of the first fixed bracket 51 squeezes the pressure sensor 70 in the extension direction of the guide rail 30, so that the pressure sensor 70 can collect the squeezing force in the extension direction of the guide rail 30, and can eliminate the invalid forces on the pressure sensor 70 in other directions. Therefore, the limit rod of the present invention can collect the effective force during rowing, which is convenient for adjusting the posture and strength of the athlete's feet during use.

[0044] The back side of the bottom plate of the second fixed bracket 52 has a plane, which is parallel to the second contact surface 621, wherein the plane is used to low-pressure the pressure sensor 70 on the second contact surface 621, for detecting the outward force of the seat 21 along the guide rail 30, the bottom plate of the second fixed bracket 52 has a through hole, and a second limiting rod 6211 is connected to the second contact surface 621 of the second sensor bracket 62, and the second limiting rod 6211 passes through the through hole, wherein the diameter of the second limiting rod 6211 is smaller than the corresponding through hole diameter, and the interruption length of the second limiting rod 6211 is greater than the thickness of the fixing plate of the second fixed bracket 52, so that the fixed bracket 50 has a certain degree of freedom of movement in the extension direction of the guide rail 30, wherein the length of the degree of freedom of movement can be 1-2cm, the The second fixed bracket 52 connects the slide rail 40 and the seat 21, so that the seat 21 can be moved on the guide rail 30. When the seat 21 moves along the guide rail 30 toward the second contact surface 621, the limit rod is squeezed by the back side of the bottom plate of the second fixed bracket 52, so that the pressure sensor 70 located on the second contact surface 621 collects the force of the seat 21 in the extension direction of the guide rail 30. The force in this direction can be obtained by the cooperation between the guide rail 30 and the limit rod, and the pressure sensor 70 on the second contact surface 621 can simultaneously eliminate the influence of the force in the direction other than the extension direction of the guide rail 30, so as to obtain the effective force of the athlete in the rowing process. Scientific and targeted training can be carried out through the effective force, which can be used to adjust the posture and strength of the rowing athlete's hips.

[0045] Furthermore, after obtaining the force values ​​of the two pressure sensors 70 of the rowing inner frame structure, by calculating the difference between the force value of the pressure sensor 70 corresponding to the pedal 20 and the force value of the pressure sensor 70 corresponding to the seat 21, and calculating the overall acceleration within a certain period of time based on the overall rowing and the mass of the athlete, the rowing effect of the athlete can be accurately obtained, which plays a better regulatory role in the overall rowing training.
