[0027] Example
[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, an intelligent controlled stair climbing machine proposed in one embodiment of the present invention comprises a base plate 1, a track wheel body 2 is mounted on the base plate 1, a mounting plate 3 is fixed on the top of the base plate 1, a transmission shaft 4 is rotatably connected to the side wall of the mounting plate 3 through a bearing, a driving bevel gear 5 is fixed to the bottom end of the transmission shaft 4, a driven bevel gear 6 is fixed to the driving shaft surface of the track wheel body 2, the driven bevel gear 6 is meshed and connected with the driving bevel gear 5, a guide seat 7 is fixed to the top of the base plate 1, two friction wheels 8 are fixed to the driving shaft surface of the track wheel body 2, two brake blocks 9 adapted to the friction wheels 8 are slidably connected to the guide seat 7, an electric push rod 10 is fixed to the top of the base plate 1, a U-shaped plate 11 is fixed to the ejection end of the electric push rod 10, and a bearing plate 15 is fixed to the top of the bearing plate 15. The limiting plate 27 matched with the U-shaped plate 11, the U-shaped plate 11 slides on the surface of the limiting plate 27, which can play the role of auxiliary guiding support for the U-shaped plate 11, so that it will be more stable during the movement. The inner walls on both sides of the U-shaped plate 11 are rotatably connected with the connecting rod 12 through the pin shaft, and the other ends of the connecting rod 12 are rotatably connected with the corresponding brake blocks 9 respectively. The top of the guide seat 7 is provided with an auxiliary brake assembly 13 for secondary limiting the driving shaft of the crawler wheel body 2. A connecting shaft 14 is rotatably provided between the inner walls on both sides of the bottom plate 1 through a bearing, and a bearing plate 15 is fixed on the surface of the connecting shaft 14. Two cylinders 28 for buffering the falling bearing plate 15 are fixed on the top of the bottom plate 1. The cylinders 28 are made of rubber. When the bearing plate 15 When falling, it can avoid direct contact with the components at the bottom thereof and collision. Two hydraulic cylinders 16 are installed on the top of the bottom plate 1, and the ejection ends of the hydraulic cylinders 16 are movably connected to the bottom of the bearing plate 15. A seat plate 17 is arranged above the bearing plate 15, and a backrest plate 18 is rotatably connected to the seat plate 17. L-shaped plates 19 are fixed on both sides of the bottom of the seat plate 17, and two telescopic sleeves 20 are fixed on the top of the L-shaped plate 19, and side handrails 21 are fixed to the tops of the two corresponding telescopic sleeves 20. A handle 22 is installed on the seat plate 17, and a height adjustment mechanism 23 for driving the seat plate 17 to move up and down is arranged on the bearing plate 15. When using this intelligent control stair climbing machine, the elderly or users with inconvenient legs and feet can sit directly on the seat plate 17.

Finally, the stair climbing machine is equipped with a power supply battery, and the power supply battery is rechargeable, which can be charged with a household power supply, and is convenient to use. ,
[0029] like Figure 4 and Figure 5 As shown, in some embodiments, the auxiliary brake assembly 13 includes two positioning shafts 1301 rotatably connected to the top of the guide seat 7 through bearings, and the surfaces of the positioning shafts 1301 are fixed with transmission gears 1302. Two racks 1303 are fixed to the inner wall of one side of the U-shaped plate 11. Two racks 1304 are slidably connected to the top of the guide seat 7. The racks 1303 and the racks 1304 are respectively meshed and connected with the corresponding transmission gears 1302. Two brake gears 1305 are fixed to the surface of the driving shaft of the crawler wheel body 2, and one end of the racks 1304 is fixed with brake gears adapted to the brake gears 1305. Block 1306, when in use, when the U-shaped plate 11 moves, it will drive the two racks 1303 to move synchronously, and after the rack 1303 moves, it can drive the rack 2 1304 to move in the opposite direction with the cooperation of the transmission gear 1302, and the rack 2 1304 will drive the brake tooth block 1306 to engage with the brake gear 1305, then the driving shaft of the crawler wheel body 2 can be limited again, so as to further prevent it from loosening, and when the brake tooth block 1306 and the brake gear 1305 are engaged, since the brake gear 1305 can rotate to make way, there will be no conflict and jamming when the two are engaged.
[0030] like Figure 2 and Figure 6As shown, in some embodiments, the height adjustment mechanism 23 includes a surrounding plate 2301 fixed at the opening of the supporting plate 15, and an electric push rod 2302 and four telescopic sleeves 2303 are fixed inside the surrounding plate 2301. The ejection end of the electric push rod 2302 and the top of the four telescopic sleeves 2303 are fixedly connected to the bottom of the seat plate 17, and a telescopic protective cover 2304 is fixed to the top of the supporting plate 15, and the top of the telescopic protective cover 2304 is fixedly connected to the bottom of the seat plate 17.
