[0028] Please see Figure 1-5 As shown, this utility model is a downward rotating flip-up step, including a frame assembly 1, a cylinder assembly 2, and a pedal surface assembly 3, and also includes:

[0029] Left side plate 101 and right side plate 102 are set on the left and right sides of frame assembly 1. A lower reinforcing rib 104 is provided between left side plate 101 and right side plate 102, and an upper reinforcing rib 105 is fixed to the upper end of the lower reinforcing rib 104. The cross-section between left side plate 101 and right side plate 102 is an "L" shaped structure, and multiple sets of mounting holes are provided on the top of both left side plate 101 and right side plate 102. Through the mounting holes at the top of left side plate 101 and right side plate 102, it is convenient to connect and fix left side plate 101 and right side plate 102 to the bus, which facilitates subsequent processing. Then, the lower reinforcing rib 104 and upper reinforcing rib 105 can strengthen and reinforce the connection between left side plate 101 and right side plate 102, thereby preventing left side plate 101 and right side plate 102 from shaking.

[0030] A sliding limiting mechanism is located inside the left side plate 101 and the right side plate 102, used to limit the angle adjustment of the pedal surface assembly 3. The sliding limiting mechanism includes a guide stop plate 103, a tension spring 107, a sliding bearing 108, a washer 112, and a guide shaft 308. The guide stop plate 103 is a ring structure installed at the lower end of the left side plate 101 and the right side plate 102. A connecting groove is opened inside the guide stop plate 103. The tension spring 107 is rotatably connected to the inner side of the left side plate 101 and the right side plate 102, and the tension spring 108... The other end of 07 is connected to the guide stop plate 103. A sliding bearing 108 is fixed to the inner side of the right side plate 102, and the connecting groove inside the guide stop plate 103 slides on the outer side of the sliding bearing 108. A gasket 112 is provided at the tail end of the guide stop plate 103, and the other end of the guide stop plate 103 is connected to the guide shaft 308. The sliding bearing 108 allows the guide stop plate 103 to rotate, and the guide stop plate 103 can slide on the sliding bearing 108 via the connecting groove, facilitating subsequent movement. Continuing the process, the tension spring 107 can pull the guide stop 103 to reset, thus facilitating the subsequent retraction and extension of the pedal surface assembly 3. The guide stop 103 has a hole at its bottom for installing tension spring assembly one. The other end of tension spring assembly one is installed on the bottom of the left side plate 101 and the right side plate 102. Simultaneously, the reinforcing rib 104 has two rows of holes for installing tension spring assembly two. The other end of tension spring assembly two is installed on the tension spring plate 305 of the pedal surface assembly. Tension spring assembly one and tension spring assembly two are symmetrically distributed left and right. The pedal surface assembly is located on the cylinder component... When the pedal is in motion, some shaking will occur. Adding spring assembly one and spring assembly two can effectively eliminate the shaking and make the pedal run smoothly. Then, the shim 112 can be connected to the guide shaft 308 to facilitate the subsequent drive connection of the pedal surface assembly 3. The inner sides of the left side plate 101 and the right side plate 102 are symmetrically provided with shock-absorbing rubber pads 106, and the other end of the shock-absorbing rubber pads 106 is in contact with the pedal surface assembly 3. The shock-absorbing rubber pads 106 can absorb vibration and play a buffering role when the pedal surface assembly 3 is retracted.

[0031] The bracket 206 is bolted between the left side plate 101 and the right side plate 102. A drive mechanism is located inside the bracket 206 to adjust the tilt angle of the pedal surface assembly 3. The drive mechanism includes a cylinder 201, a first cylinder tailstock 202, a second cylinder tailstock 203, a first pin 204, a second pin 205, a tension spring plate 305, and a cylinder connecting plate 309. The cylinder 201 is positioned at the center of the bracket 206. The first cylinder tailstock 202 is fixed to the side of the cylinder 201 closest to it. The second cylinder tailstock 203 is fixed at the center of the bracket 206. The first cylinder tailstock 202 and the second cylinder tailstock 203 are connected at the center by the first pin 204. The second pin 205 is fixed to the output end of the cylinder 201. The tension spring plate 305 is laterally fixed to the inner side of the welded frame 301. The cylinder connecting plate 309 is... The cylinder is fixed at the center of the upper end face of the tension spring plate 305, and the cylinder connecting plate 309 is connected to the second pin 205. The two ends of the cylinder component 201 are connected to the cylinder tail seat 202 and the second cylinder tail seat 203 through the cylinder tail seat 1 202. The cylinder tail seat 1 202 and the second cylinder tail seat 203 are limited by the first pin 204. Then, the second pin 205 can be connected to the cylinder connecting plate 309 at the center of the tension spring plate 305, so that the pedal surface assembly 3 can be adjusted. Since both ends of the cylinder component 201 are fixed by hinge, the installation is convenient. At the same time, since the pedal surface assembly 3 uses a cylinder as the power source, the service life of the pedal surface assembly 3 is guaranteed. The service life of the cylinder is much longer than that of the pedal powered by the motor. After the pedal surface assembly 3 is installed, in the overall retracted state, the pedal surface assembly 3 is completely hidden inside the bottom of the bus, and the overall shape of the bus body is beautiful.

[0032] A welding frame 301 is disposed inside the pedal surface assembly 3. A panel 302 is fixed to one side of the pedal surface assembly 3, and an outer surface 4 is disposed on the outer side of the panel 302. A fixing plate 303 is fixed to one side of the welding frame 301, and a pipe plug 310 is fixed to one end of the fixing plate 303. A sliding bearing 110 is rotatably connected to the inner side of the right side plate 102. A sliding bearing 109 is disposed inside the sliding bearing 110, and a retaining spring 111 is fixed to one end of the sliding bearing 109. A rotating bushing 306 is symmetrically disposed inside the welding frame 301, and the rotating bushing 306 can be connected to the sliding bearing 109. The rotating bushing 306 can be connected to the sliding bearing 109 and the sliding bearing 110, so that they can move relative to each other, driving the pedal surface assembly 3 to rotate, realizing the extension and retraction of the pedal. Then, the retaining spring 111 can limit the connection between the sliding bearing 110 and the rotating bushing 306. The connection is fixed to prevent misalignment and shaking at the joint, which would affect the subsequent driving adjustment of the pedal surface assembly 3. A reinforcing plate 304 is evenly provided on one side of the welding frame 301 and connected to the panel 302 by bolts. A transition plate 307 is provided on the left and right sides of the welding frame 301, and the other end of the transition plate 307 contacts the panel 302. The reinforcing plate 304 can strengthen the connection between the welding frame 301 and the panel 302, preventing misalignment. The transition plate 307 can further improve the connection effect on the side. An appearance surface 4 can be provided on the outside of the panel 302, which serves a decorative purpose when the pedal is retracted. In addition, an outer shell can be provided on the outside of the welding frame 301 and the panel 302, which can protect the pedal surface assembly 3 and has anti-slip texture on its surface, thereby preventing slippage during riding and affecting subsequent processing.

[0033] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
