[0026] Please see Figures 1 to 3 This utility model provides an intelligent adjustable fitness equipment, which includes: a base 100, two push rods 400 and a counterweight assembly 500. The top of the base 100 is provided with a seat mounting frame 110. A seat cushion 200 and a backrest 300 are mounted on the seat mounting frame 110. The seat cushion 200 is mounted on the bottom of the seat mounting frame 110 in a height-adjustable manner via a first adjustment assembly 210. The backrest 300 is located on the upper side of the seat cushion 200. The bottom of the backrest 300 is rotatably connected to the seat mounting frame 110. The top of the backrest 300 is connected to the seat mounting frame 110 via a second adjustment assembly 310. The second adjustment assembly 310 is used to adjust the angle of the backrest 300. Two push rods 400 are located on both sides of the seat mounting bracket 110. The bottoms of the two push rods 400 are rotatably connected to the base 100. Each of the two push rods 400 has a handle 410 on its top. The handle 410 is rotatably adjustable on the top of the push rod 400 via a third adjusting component 420. The counterweight component 500 is installed at the end of the base 100 away from the seat cushion 200. The counterweight component 500 includes a servo motor 510 and a reducer 520. The output end of the servo motor 510 is connected to the input end of the reducer 520. The output end of the reducer 520 is connected to two linkage components 600. The other ends of the two linkage components 600 are rotatably connected to the two push rods 400. A controller 800 is installed at the other end of the base 100. The controller 800 is electrically connected to the counterweight component 500.
[0027] This invention features a base 100 that allows the seat to be placed on the ground or a base surface. A seat mounting bracket 110 on the base 100 is used to mount a seat cushion 200 and a backrest 300. A first adjustment component 210 adjusts the height of the seat cushion 200 on the mounting bracket 110, and a second adjustment component 310 adjusts the angle of the backrest 300 on the mounting bracket 110, ensuring the positions of the seat cushion 200 and backrest 300 are suitable for the body shape of the exerciser and improving comfort during exercise. A third adjustment component 420 adjusts the position of the handle 410 on the push rod 400, making it more comfortable for the exerciser to hold the handle 410. The counterweight assembly 500 drives the reducer 520 via a servo motor 510, giving the reducer 520 a certain torque at its output. When the exerciser pushes the push rod 400, the push rod 400 drives the connecting rod assembly 600, turning the torque at the reducer 520's output into resistance on the push rod 400. This resistance continuously acts on the push rod 400, allowing the exerciser to complete concentric and eccentric training through repeated pushing and pulling of the push rod 400. The controller 800 adjusts the torque of the counterweight assembly, thereby changing the resistance applied to the push rod 400. The controller 800 can also adjust parameters such as exercise intensity, mode, and resistance, and has data collection and analysis functions. It should be noted that the method of adjusting exercise intensity, mode, and resistance parameters and collecting and analyzing data through the controller 800 is existing technology and will not be detailed here.
