Technical Field
[0001] This utility model relates to the field of bus door steps, and in particular to an electric push-step structure. Background Technology
[0002] Currently, most bus door steps use manual or simple electric folding structures. Manual steps require passengers or drivers to get off the bus to operate, which is inconvenient; electric folding steps are usually driven by a motor or push rod to realize the unfolding and folding of the step plate, and have been used in a variety of buses.
[0003] After the vehicle comes to a complete stop, the control system receives a command and activates the electric push rod, which pushes the movable step plate from the storage position to the horizontal working position through the linkage mechanism. After the passenger finishes using the vehicle, the electric push rod is pulled in the opposite direction to retract and lock the step plate.
[0004] However, existing electric steps are prone to vibration and noise during the unfolding and retraction process due to mechanical gaps and impacts, affecting the riding experience; the surface of the step plate is prone to dust accumulation and lacks self-cleaning function, requiring regular manual cleaning; some structures rely solely on the front hinge for support after being fully unfolded, and the load-bearing stability needs to be improved. Therefore, an electric push-to-step structure is proposed to solve the above problems. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Reference Figure 1 The present invention provides an embodiment of an electric push-step structure, including a mounting frame 1. A lighting lamp 4 is fixedly mounted on the front of the mounting frame 1. There are four lighting lamps 4, which are symmetrically arranged on both sides of the front of the mounting frame 1. The lighting lamps 4 illuminate the step mechanism 2 at night, making it convenient for users to use at night. The step mechanism 2 is provided on the inner wall of the mounting frame 1, making it convenient for users to get off the vehicle.
[0027] Reference Figure 2 - Figure 4The stepping mechanism 2 includes a first electric push rod 21, one end of which is hinged to the back of the inner wall of the mounting frame 1. This push rod is used to retract the first movable pedal 210 and the second movable pedal 213. A reciprocating assembly 22 is fixedly connected to the output end of the first electric push rod 21, which drives the first movable pedal 210 and the second movable pedal 213 to move slightly, thereby shaking off dust from the first movable pedal 210 and the second movable pedal 213. A rotating shaft 23 is rotatably connected to the reciprocating assembly 22. The reciprocating assembly 22 includes a first mounting plate 221. The back of the first mounting plate 221 is fixedly connected to the output end of the first electric push rod 21, and a damping rod 222 is fixedly connected to the front of the first mounting plate 221. A second mounting plate 223 is fixedly connected to the front of the damping rod 222. A spring 224 is sleeved on the outer wall of the damping rod 222. Through the setting of the damping rod 222 and the spring 224, the first movable pedal 210 and the second movable pedal 213 can be damped, improving the comfort of the stepping mechanism 2. The two ends of the spring 224 are fixedly connected to the front of the first mounting plate 221 and the second mounting plate 223 respectively. An electromagnet 225 is fixedly installed on the front of the first mounting plate 221, and a permanent magnet 226 is fixedly installed on the back of the second mounting plate 223. By setting the electromagnet 225 and the permanent magnet 226, the rotating block 25 can be driven to swing slightly through magnetic force, thereby driving the first movable pedal 210 and the second movable pedal 213 to move slightly. The second mounting plate 223 is fixedly connected to a rotating sleeve 227 on its front side, and the inner wall of the rotating sleeve 227 is rotatably connected to the outer wall of the rotating shaft 23. The inner wall of the mounting frame 1 is fixedly connected to two fixed shafts 24, which are symmetrically arranged on the side of the fixed pedal 27 to improve its stability. A rotating block 25 is rotatably fitted onto the outer wall of the fixed shaft 24, and one end of the rotating block 25 is rotatably connected to the rotating shaft 23. The inner wall of the mounting frame 1 is fixedly connected to a fixed rod 26, and the outer wall of the fixed rod 26 is fixedly fitted with a fixed pedal 27. The side of the fixed pedal 27 is hinged with a first hinge rod 28 and a third hinge rod 211 to drive the first movable pedal. The plate 210 is retracted and extended. The middle of the first hinge rod 28 is hinged to the second hinge rod 29, and one end of the second hinge rod 29 is hinged to the other end of the rotating block 25. The bottom of the first hinge rod 28 and the middle of the third hinge rod 211 are hinged to the first movable pedal 210. The bottom of the third hinge rod 211 is hinged to the second movable pedal 213. The tops of the fixed pedal 27, the first movable pedal 210 and the second movable pedal 213 are all fixedly connected with anti-slip pads. By setting anti-slip pads, the stability of the first movable pedal 210 and the second movable pedal 213 can be improved. The side of the first movable pedal 210 is hinged to the fourth hinge rod 212, and the bottom of the fourth hinge rod 212 is hinged to the middle of the side of the second movable pedal 213.
[0028] Reference Figure 2 ,Figure 3 , Figure 5 The bottom of the second movable pedal 213 is provided with a support mechanism 3. The support mechanism 3 includes a fixed frame 31. The top of the fixed frame 31 is fixedly connected to the bottom of the second movable pedal 213 for retracting the support plate 37. The side of the fixed frame 31 is provided with a sloping groove 32. The back of the fixed frame 31 is fixedly installed with a second electric push rod 33 for pushing the push plate 34 to move. The output end of the second electric push rod 33 moves through the back of the fixed frame 31 and is fixedly connected to the push plate 34. The inner wall of the sloping groove 32 is slidably connected with two slide rods 36. The front of the push plate 34 is fixedly connected with a locking block 35. The locking block 35 is located between the two slide rods 36 and contacts the opposite surfaces of the two slide rods 36. The inner wall of the sloping groove 32 is slidably connected with slide rods 36. The side of the slide rods 36 is fixedly connected with a support plate 37. The locking block 35 can stably drive the two slide rods 36 to move along the sloping groove 32.
[0029] Working principle: When in use, activating the first electric push rod 21 moves the reciprocating assembly 22, which in turn causes one end of the rotating block 25 to swing via the rotating shaft 23. This, in turn, causes the other end of the rotating block 25 to swing the second hinge rod 29, which in turn pushes the first hinge rod 28 to swing. The swinging of the first hinge rod 28 causes the third hinge rod 211 to swing, thus extending the first movable pedal 210. Simultaneously, the swinging of the third hinge rod 211 causes the fourth hinge rod 212 to swing, extending the second movable pedal 213. Then, activating the second electric push rod 33 moves the push plate 34, which in turn moves the locking block 35. This, in turn, causes the support plate 37 to extend via the slide rod 36, thus connecting the support plate 37 to the ground. The surface is in contact, thereby improving the stability of the stepping mechanism 2. At the same time, the setting of damping rod 222 and spring 224 can improve the stability of the user during use. After use, the first movable pedal 210 and the second movable pedal 213 are put into the mounting frame 1. By continuously switching the current direction of electromagnet 225, when electromagnet 225 is energized, it will generate an attractive force on permanent magnet 226 with the opposite magnetic pole. When the current direction of electromagnet 225 is switched, it will generate a repulsive force with the same magnetic pole as permanent magnet 226. Thus, the rotating block 25 is driven to swing slightly through the rotating shaft 23, thereby shaking the first movable pedal 210 and the second movable pedal 213 and shaking off the dust on the first movable pedal 210 and the second movable pedal 213.
[0030] It is worth noting that in this embodiment, the electrical equipment is a common device in the prior art, and the model used can be customized according to actual usage requirements. The power supply interface of the electrical equipment in this utility model is connected to the power supply system through a switch (not shown in the figure) and a wire (not shown in the figure) to realize its control. The circuits and controls involved are all prior art and are known in the current field, so they will not be described in detail here.
[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
