[0037] Please refer to the following: Figures 1 to 5The first embodiment of the present application provides a left-right direction angle adjustable backboard 30 for user pedaling training, which is mainly composed of a pivot connecting part 34, a backboard body 21, a support plate 22 and a left-right horizontal moving part 33, and collectively realizes the angle adjustment function of the backboard in the left-right direction to meet the body posture needs of different users in the pedaling training process and improve the comfort and scientificity of the training. The pivot connecting part 34 rotatably connects the backboard body 21 with the pedaling machine to provide stable support and a certain degree of rotational freedom for the backboard. The backboard body 21 is the main structure on which the user lies in the pedaling training, and the upper back-lying end 211 thereof provides lying support for the user, and the lower abutting end 212 cooperates with the left-right horizontal moving part 33 to ensure that the backboard can be flexibly adjusted in the left-right direction. The support plate 22 is located below the backboard body 21 and is connected with the pedaling machine body to play a stable supporting role. One end of the left-right horizontal moving part 33 is fixed on the support plate 22, and the other end thereof abuts against the abutting groove 2121 through the abutting piece 2321. When the user adjusts the left-right direction angle of the backboard, the left-right horizontal moving seat 333 slides on the fixed base 331, thereby driving the abutting rod 332 to move leftward and rightward in the abutting groove 2121. The semicircular, semicircular or arc shape of the abutting groove 2121 enables the abutting piece 2321 to smoothly slide during the movement while maintaining stability and reliability. By rotating the knob part 3311, the user can accurately control the moving distance and position of the left-right horizontal moving seat 333. The scale marks provided on the knob part 3311 facilitate the user to accurately adjust, thereby ensuring that the backboard reaches the ideal positioning effect when the left-right direction angle is adjusted. The backboard groove 2111 is located on the back-lying end 211, and a plurality of backboard blocks 2112 are arranged inside the backboard groove 2111. The arc or curved structure of the cross section of the back-lying end 211 helps to enhance the back fitting degree of the user and provide a more comfortable training experience.

[0038] For reference Figures 1 to 4 In some embodiments, the left-right direction angle adjustable backboard 30 comprises a pivot connecting part 34, a backboard body 21, a support plate 22 and a left-right horizontal moving part 33. The pivot connecting part 34 is used to rotatably connect with the pedaling machine. The backboard body 21 is connected with the pivot connecting part 34. The support plate 22 is used to connect with the pedaling machine body. The support plate 22 is arranged below the backboard body 21. One end of the left-right horizontal moving part 33 is fixedly arranged on the support plate 22, and the other end thereof abuts against the backboard body 21, thereby realizing the adjustability of the left-right direction angle of the backboard of the pedaling machine. The user can freely adjust the angle of the backboard according to the personal physical condition and training needs, so as to better correct the left-right deviation of the spine and improve the comfort and effectiveness of the training. The applicability and human engineering design level of the pedaling machine are improved, and the training experience of the user is enhanced.

Wherein, by twisting the knob part 3311, the left and right movement of the left and right horizontal moving seat 333 is driven, and the sliding of the abutting part 2321 in the abutting groove 2121 is driven, so as to realize the adjustment of the left and right direction angle of the back plate body 21, and then the user can realize the movement of the left and right horizontal moving seat 333 by rotating the knob, so as to drive the abutting part 2321 to slide in the abutting groove 2121, adjust the left and right direction angle of the back plate, and reduce the use threshold, and facilitate the operation requirements of different users.

[0044] In some embodiments, the specific working principle that the user can realize the movement of the left and right horizontal moving seat 333 by rotating the knob is that when the user rotates the knob part 3311, the knob part 3311 is usually provided with a threaded structure or a gear transmission device, and the rotary motion of the knob is converted into linear transmission motion through the rotating operation. This transmission mechanism can be screw transmission or gear and rack transmission, so that the left and right horizontal moving seat 333 moves smoothly left and right along the guide structure of the fixed base 331. In this process, there is a precise meshing structure between the left and right horizontal moving seat 333 and the fixed base 331, which ensures that the rotation of the knob can be accurately transmitted to the left and right horizontal moving seat 333, realizing the fine adjustment of the left and right horizontal moving seat 333. At the same time, the knob part 3311 is provided with scale marks, and the user can intuitively observe the displacement degree of the left and right horizontal moving seat 333 through these marks, ensuring the accuracy and controllability of the adjustment.
