[0032] A positioning slide 107 is slidably mounted on the switching ring frame 102, a positioning pulley 117 is rotatably mounted on the switching ring frame 102, a positioning screw rod 115 is fixedly mounted on the positioning slide 107, the positioning screw rod 115 and the positioning pulley 117 form a spiral pair, a positioning motor 116 is fixedly mounted on the switching ring frame 102, a transmission pulley 119 is fixedly mounted on the output shaft of the positioning motor 116, and a transmission belt 118 is arranged between the transmission pulley 119 and the positioning pulley 117.

The two leg-split slides 108 are symmetrically slidably mounted on the positioning slide 107. A double-headed threaded lead screw 124 is rotatably mounted on the positioning slide 107. The threads at both ends of the double-headed threaded lead screw 124 respectively form a spiral pair with the corresponding leg-split slides 108. A rotary damper 125 and a leg-split motor 126 are fixedly mounted on the positioning slide 107. The output shaft of the leg-split motor 126 is fixedly connected to the double-headed threaded lead screw 124. The rotary damper 125 is connected to the end of the double-headed threaded lead screw 124 farthest from the leg-split motor 126. The rotary damper 125 is used to limit the rotation of the double-headed threaded lead screw 124.

[0034] Start the leg-split motor 126 to drive the double-headed threaded screw 124 to rotate. Under the action of the double-headed threaded screw 124, the two leg-split slides 108 move away from or towards each other. Under the action of the rotary damper 125, the rotation speed of the double-headed threaded screw 124 is limited, thereby limiting the movement speed of the leg-split slide 108.

[0035] The supporting assembly includes two leg-split swivel plates 109, and the leg-split slide plates 108 are both rotatably mounted with bar-shaped swivel blocks 132. The leg-split swivel plates 109 are slidably matched with the corresponding bar-shaped swivel blocks 132. An auxiliary unit is arranged between the two leg-split swivel plates 109 and the position-adjusting slide plate 107. The auxiliary unit is used to adjust the positions of the two leg-split swivel plates 109. The auxiliary unit includes an auxiliary slide plate 120 slidably mounted on the position-adjusting slide plate 107, and a distance-adjusting slide plate 121 is symmetrically slidably mounted on the auxiliary slide plate 120. A distance-adjusting rod 122 is fixedly mounted on the side of the leg-split swivel plate 109, and the two distance-adjusting rods 122 are rotatably connected to the corresponding distance-adjusting slide plates 121 respectively. A square groove 123 is fixedly arranged on the leg-split slide plate 108, and the square groove 123 is used to make way for the rotation of the leg-split swivel plates 109.

[0036] A double-threaded short lead screw 130 is rotatably mounted on the auxiliary slide 120, and the threads at both ends of the double-threaded short lead screw 130 respectively form a spiral pair with the corresponding pitch-adjusting slide 121; a pitch-adjusting motor 129 is fixedly mounted on the auxiliary slide 120, and the output shaft of the pitch-adjusting motor 129 is fixedly connected to the double-threaded short lead screw 130; an auxiliary lead screw 127 is rotatably mounted on the position-adjusting slide 107, and the auxiliary lead screw 127 and the auxiliary slide 120 form a spiral pair; an auxiliary motor 128 is fixedly mounted on the position-adjusting slide 107, and the output shaft of the auxiliary motor 128 is fixedly connected to the auxiliary lead screw 127.

[0037] In the initial position, the two leg-split slides 108 are located closest to each other, the two distance-adjusting slides 121 are located farthest from each other, the two leg-split rotating plates 109 are located in the area between the two leg-split slides 108, and at this time, the two leg-split rotating plates 109 are both in a vertical downward position.

[0038] The auxiliary motor 128 is started to drive the auxiliary screw rod 127 to rotate, that is, the auxiliary slide plate 120 is driven to move relative to the position adjustment slide plate 107, and the distance adjustment slide plate 121 on the auxiliary slide plate 120 moves synchronously. Under the action of the distance adjustment rod 122, the two leg-split rotating plates 109 move synchronously, that is, the leg-split rotating plates 109 slide relative to the corresponding bar-shaped rotating blocks 132, and the distance of the leg-split rotating plates 109 extending out of the upper surface of the leg-split sliding plates 108 is adjusted according to the leg length of the trainee. The distance adjustment motor 129 is started to drive the double-threaded short screw rod 130 to rotate, that is, the leg-split rotating plates 109 extend out of the upper surface of the leg-split sliding plates 108, and the distance adjustment motor 129 is started to drive the double-threaded short screw rod 130 to rotate. The two distance-adjusting skateboards 121 move in a direction away from each other or in a direction toward each other. Therefore, according to the leg gap of the trainee, the auxiliary motor 128 is started to adjust the distance between the two distance-adjusting skateboards 121. Under the action of the auxiliary skateboard 120, the two leg-split rotating plates 109 move synchronously. When the auxiliary motor 128 is started, the leg-split motor 126 is started at the same time to make the two leg-split skateboards 108 move synchronously. When the distance-adjusting skateboard 121 moves, the leg-split skateboard 108 moves synchronously, thereby making the leg-split rotating plate 109 always in a vertical state.

[0039] After completing the position adjustment of the split-leg rotating plate 109, the trainee stands on the two split-leg sliding plates 108 with two feet respectively, and then starts the split-leg motor 126 to drive the two split-leg sliding plates 108 to move away from each other, and starts the auxiliary motor 128 to drive the auxiliary sliding plate 120 to move downward, that is, the two split-leg rotating plates 109 move downward, so that the trainee's two feet move away from each other, that is, the trainee's two legs are separated. During the movement of the split-leg sliding plates 108, the bar rotating block 132 rotates relative to the corresponding split-leg sliding plate 108, and the split-leg rotating plate 132 rotates. The plate 109 slides relative to the bar rotating block 132, so that when the trainee's legs are separated, the leg-separating rotating plate 109 always supports the trainee's corresponding legs, so that the trainee's legs can be separated slowly to prevent the trainee from being injured by the leg-separating rotating plate 109 when the leg-separating rotating plate 109 moves to a horizontal state, and the trainee is in a horizontal or vertical split state during the splits, and the leg-separating rotating plate 109 is located on the inner side of the square groove 123, that is, the square groove 123 gives way to the rotation of the leg-separating rotating plate 109, so that the leg-separating rotating plate 109 can move to a horizontal state.

[0040] The auxiliary unit includes a transmission long shaft 133 and a circular rotating plate 103. When the circular rotating plate 103 and the transmission long shaft 133 are engaged, they are used to manually adjust the position of the leg rotating plate 109. A gear box 137 is also fixedly installed on the adjustment slide 107. The double-headed threaded long screw rod 124 is fixedly connected to the input end of the gear box 137. A splined long shaft 131 is fixedly installed on the output end of the gear box 137. An auxiliary pulley 134 is rotatably installed on the auxiliary slide 120. The auxiliary pulley 134 and the splined long shaft 131 form a spline sliding fit. The transmission long shaft 133 is rotatably installed on the auxiliary slide 120. A linkage pulley 136 is fixedly installed on the transmission long shaft 133, and a linkage belt 135 is arranged between the linkage pulley 136 and the auxiliary pulley 134.

[0041] A threaded short rod 138 is fixedly provided at the end of the transmission long shaft 133 farthest from the linkage pulley 136, and a connecting rod 110 is fixedly provided on the circular rotating plate 103. The connecting rod 110 is slidably matched with the supporting panel 106. When the end of the connecting rod 110 farthest from the circular rotating plate 103 is engaged with the threaded short rod 138, a spiral pair is formed. A fan-shaped cover plate 114 is also fixedly provided on the switching ring frame 102, and a chamber is formed between the fan-shaped cover plate 114 and the switching ring frame 102. The auxiliary unit is located inside the chamber formed between the switching ring frame 102 and the fan-shaped cover plate 114, that is, the fan-shaped cover plate 114 is used to protect the components inside the chamber formed by the switching ring frame 102 and the fan-shaped cover plate 114.

[0042] When the positioning slide 107 is in a horizontal state, the circular rotating plate 103 is placed on the supporting panel 106. At this time, the end of the threaded short rod 138 farthest from the linkage pulley 136 is located below the end of the leg rotating plate 109 farthest from the linkage pulley 136. At this time, the upper surface of the positioning slide 107 and the upper surface of the supporting base plate 101 are on the same plane.

[0043] Start the switching motor 111 to drive the switching ring frame 102 to rotate 90 degrees, so that the supporting panel 106 is in a horizontal state, and the supporting back plate 104, the square cushion 105, and the supporting panel 106 form a split-leg exercise seat, and then the connecting rod 110 on the circular rotating plate 103 is engaged with the threaded short rod 138, and the circular rotating plate 103 is driven to rotate. Under the action of the connecting rod 110 and the threaded short rod 138, the transmission long shaft 133 rotates synchronously, and then under the action of the auxiliary pulley 134, the linkage belt 135, and the linkage pulley 136, the spline long shaft 131 rotates synchronously, and under the action of the gear box 137, the double-headed threaded long screw 124 is manually driven to rotate, and when the auxiliary slide plate 120 slides relative to the adjustment slide plate 107, the auxiliary pulley 134 rotates relative to the spline long shaft 131.

[0044] When the support panel 106 is in a horizontal state, the trainee sits on the square cushion 105, with his back against the support backboard 104, and then stretches his legs straight toward the positioning slide 107, and then starts the positioning motor 116 to drive the transmission pulley 119 to rotate. Under the action of the transmission belt 118, the positioning pulley 117 rotates synchronously, thereby making the positioning screw rod 115 move toward the direction close to the support backboard 104, and the positioning slide 107 moves synchronously, and finally makes the leg-split slide 108 contact the trainee's two legs respectively, and then starts the auxiliary motor 116 to drive the transmission pulley 119 to rotate. The machine 128 drives the two leg-split rotating plates 109 to move towards the supporting back plate 104. The trainee's leg length adjusts the extended length of the leg-split rotating plates 109, and then the circular rotating plate 103 is manually rotated to make the two leg-split sliding plates 108 move away from each other, that is, the ends of the two leg-split rotating plates 109 farthest from the supporting back plate 104 move away from each other, that is, the leg-split rotating plates 109 are tilted. Under the action of the leg-split rotating plates 109, the trainee's two legs are separated, that is, the trainee can perform leg-split exercises while sitting.

[0045] Working principle: The support base plate 101 is installed on the ground, and the upper surface of the support base plate 101 is flat against the ground.

[0046] When the trainee performs splits exercise, the support panel 106 is in a vertically upward state, and then the upper surface of the adjustment slide plate 107 and the upper surface of the support base plate 101 are in the same plane. The trainee then stands on the split slide plate 108, with both feet stepping on different split slide plates 108. The split motor 126, the auxiliary motor 128, and the distance adjustment motor 129 are then started to adjust the position of the split rotating plate 109 according to the trainee's leg length and leg gap. After completing the position adjustment of the split rotating plate 109, the split motor 126 is started to move the two split slide plates 108 away from each other, and the auxiliary motor 128 is started to move the auxiliary slide plate 120 toward the auxiliary motor 128, that is, the end of the split rotating plate 109 farthest from the auxiliary motor 128 is moved toward the auxiliary motor 128, and the split rotating plate 109 supports the trainee and moves slowly downward, thereby achieving auxiliary adjustment of the trainee's aerobics body.

[0047] When the trainee is sitting to adjust his body shape, the switching motor 111 is started to drive the switching ring frame 102 to rotate, so that the supporting panel 106 is in a horizontal state, and then the circular rotating plate 103 and the transmission long shaft 133 are engaged. The trainee sits on the square cushion 105, and then adjusts the position of the leg-split rotating plate 109, and then manually rotates the circular rotating plate 103, that is, manually tilts the two leg-split rotating plates 109, and then separates the trainee's legs, that is, the trainee can sit to perform auxiliary body adjustment.
