[0040] Among them, the stepping mechanism 100 includes a pedal 120. When the safety door 200 is opened, one end of the pedal 120 away from the safety door 200 is hinged to the vehicle body 300, the first end of the guide rod 110 is hinged to the safety door 200, and the second end of the guide rod 110 is hinged to the side of the pedal 200 facing the safety door 200. At the same time, the second end of the guide rod 110 is used to move on the pedal 120. Such a configuration can drive the pedal 120 to be deployed through the guide rod 110 when the safety door 200 is opened, so that the pedal 120 is basically parallel to the ground, shortening the height of the vehicle body 300 corresponding to the safety door 200 from the ground, facilitating passengers to quickly leave the accident vehicle, improving the escape efficiency, and greatly reducing the safety hazards of passengers falling and spraining; when the safety door 200 is closed, the pedal 120 is folded and retracted under the thrust of the guide rod 110, and the pedal 120 can be located between the safety door 200 and the vehicle body 300, without occupying additional space, ensuring the safe closing of the safety door 200.

[0041] Specifically, the stepping mechanism 100 is installed with the safety door 200 opened, the pedal 120 is first hinged to the vehicle body 300, and the pedal 120 is Figure 2 In the open state shown, the second end of the guide rod 110 hinged to the pedal 120 is then moved to an end of the pedal 120 close to the vehicle body 300 , and at this time, the first end of the guide rod 110 is hingedly connected to the safety door 200 .

[0042] It should be noted that the guide rod 110 is in a Z shape, including a first rod, a second rod and a third rod connected in sequence, the first rod is arranged perpendicularly to the second rod, the third rod is arranged perpendicularly to the second rod, and the first rod is arranged parallel to the third rod, and the angle between the first rod and the third rod is 180°. In such a setting, the first rod is hinged to the pedal 120, the third rod is hinged to the safety door 200, and the end of the third rod close to the safety door 200 is provided with a second support plate 180, which is in a U shape.

The third rod passes through one of the parallel plates, and the third rod can rotate in the parallel plate, and the other parallel plate is fixedly connected to the safety door 200.

[0043] When the safety door 200 is closed, the safety door 200 gives a driving force to the guide rod 110, so that the first rod moves on the pedal 120, and then transmits the driving force to the pedal 120, and the pedal 120 rotates upward through the movement of the first rod. When the safety door 200 is completely closed, the first rod moves to the end of the pedal 120 away from the hinge of the pedal 120 and the vehicle body 300, and the pedal 120 is parallel to the substrate of the vehicle body 300, and the pedal 120 is located in the gap between the safety door 200 and the vehicle body 300.

[0044] In a feasible implementation manner, the stepping mechanism 100 further includes:

[0045] The inner box body 130 is fixedly connected to the vehicle body 300 . When the safety door 200 is opened, one end of the pedal 120 away from the safety door 200 is hinged to the inner box body 130 .

[0046] Among them, a built-in box body 130 can be set between the vehicle body 300 and the pedal 120, so that the built-in box body 130, the pedal and the guide rod 110 are sold as a whole. When not installed, the pedal 120 and the guide rod 110 are placed in the built-in box body 130, saving space and reducing transportation costs.

[0047] Specifically, during installation, the pedal 120 is unfolded, and then the built-in box body 130 is fixedly connected to the vehicle body 300, and the first rod of the guide rod 110 is moved to the end where the pedal 120 and the built-in box body 130 are hinged, and at this time, the second support plate 180 at one end of the third rod is fixedly connected to the safety door 200.

[0048] It should be noted that the third rod is hinged to a parallel plate of the second support plate 180 by providing an annular groove on the third rod, providing a through hole on the parallel plate, and the annular groove is engaged with the through hole, that is, the diameter of the through hole is smaller than the outer diameter of the third rod and the diameter of the through hole is larger than the inner diameter of the annular groove, so that the third rod and the second support plate 180 can be hinged.

The hinge of the third rod and the second support plate 180 can also be other hinge forms that can be thought of in the art, such as providing a ball head at the end of the third rod away from the second rod, and providing a spherical groove on a parallel plate of the second support plate 180, which can also achieve the hinge of the third rod and the second support plate 180, which will not be repeated here.

[0049] Figure 4 It is a schematic diagram of a hinge mechanism according to an embodiment of the utility model.

[0050] In a possible implementation, Figure 4 As shown, the stepping mechanism 100 further includes:

[0051] The hinge mechanism 140 includes a first hinge end 141 and a second hinge end 142. The first hinge end 141 includes a first connecting plate 1411 and a first connecting ear 1412 connected to each other. The first connecting ear 1412 is provided with a first through hole. The second hinge end 142 includes a second connecting plate 1421 and a second connecting ear 1422 connected to each other. The second connecting ear 1422 is provided with a second through hole. The first connecting plate 1411 is fixedly connected to the built-in box body 130, the second connecting plate 1421 is fixedly connected to the pedal 120, the first connecting ear 1412 and the second connecting ear 1422 are adjacently arranged, and the first through hole and the second through hole are aligned.

[0052] The pin shaft 150 passes through the first through hole and the second through hole.

[0053] The hinge mechanism 140 is used to realize the hinge connection between the pedal 120 and the built-in box body 130. The first connecting plate 1411 and the first connecting ear 1412 are vertically arranged, and the second connecting plate 1421 and the second connecting ear 1422 are vertically arranged. When there is only one first connecting ear 1412 and one second connecting ear 1422, the first connecting ear 1412 and the second connecting ear 1422 fit together. Two first connecting ears 1412 and one second connecting ear 1422 can also be arranged, and the second connecting ear 1422 is located between the two first connecting ears 1412. Two second connecting ears 1422 and one first connecting ear can be arranged. Ear 1412, in this case, the first connecting ear 1412 is located between the two second connecting ears 1422; two first connecting ears 1412 and two second connecting ears 1422 may also be provided, in this case, the two first connecting ears 1412 are located between the two second connecting ears 1422, or the two second connecting ears 1422 are located between the two first connecting ears 1412, or the first connecting ear 1412 and the second connecting ear 1422 are arranged at intervals, and finally the pin 150 penetrates the first through hole and the second through hole to realize the hinge connection of the first hinge end 141 and the second hinge end 142, thereby realizing the hinge connection between the built-in box body 130 and the pedal 120. Optionally, two first hinge ends 141 and two second hinge ends 142 may be provided to improve the connection strength of the hinge mechanism 140, thereby improving the stability and reliability of the unfolding and folding of the pedal 120.

[0054] It should be noted that the first connecting ear 1412 can be directly set in the built-in box body 130, and the second connecting ear 1422 can be directly fixed to the pedal 120. While realizing the hinge of the built-in box body 130 and the pedal 120, it can also reduce the volume of the stepping mechanism 100, which helps to improve the application scope of the stepping mechanism 100. That is, even if the distance between the safety door 200 and the vehicle body 300 is small, the installation and use of the stepping mechanism 100 can be realized.

[0055] It is understandable that the hinge structure 140 is not limited to one connection mode of the first hinge end 141 and the second hinge end 1422, and may also be other hinge forms known in the art such as hinge connection or hinge connection, which will not be described here.

[0056] In this embodiment, when the pedal 120 is unfolded, the length is usually 30cm to 50cm, the width is 24cm to 28cm, and the thickness is obtained according to the material and the preset bearing capacity. The above size data is only a reference and the actual selection should also be made according to the space inside the vehicle.

[0057] In a feasible implementation manner, an upper plate 310 and a lower plate 320 are provided on one side of the vehicle body 300 , the built-in box body 130 is disposed between the upper plate 310 and the lower plate 320 , and the opening end of the built-in box body 130 faces the safety door 200 .

[0058] Among them, there are an upper plate 310 and a lower plate 320 on one side of the vehicle body 300, forming a accommodating space, and the built-in box body 130 is arranged in the accommodating space and fixedly connected to the accommodating space, which can be bolted, screwed or welded, to improve the reliability of the installation of the stepping mechanism 100.

[0059] In a feasible implementation manner, the stepping mechanism 100 further includes:

[0060] The first position-limiting member 160 is disposed on a side of the pedal 120 facing the lower plate 320 when the safety door is opened, and the first position-limiting member 160 is aligned with the lower plate 320 .

[0061] Among them, the first limiter 160 is set to limit the unfolding angle of the pedal 120, thereby improving the stability of the unfolding of the pedal 120. The first limiter 160 cooperates with the safety door 200 so that the pedal 120 can be basically parallel to the ground when unfolded, ensuring the stability of passengers when stepping on it and improving the safety of passengers getting off the vehicle. Basically parallel in this application means that the angle between the pedal 120 and the ground does not exceed ±3°, and a range is set for the pedal 120 when unfolded, which ensures that the pedal 120 works stably while reducing processing accuracy, improving processing efficiency, and reducing processing costs.

[0062] It should be noted that a first limit member 160 can be set and located at the center position of the pedal 120, or two first limit members 160 can be set. In this case, the two first limit members 160 are located at both ends of the length direction of the pedal 120, further improving the stability of the pedal 120. When the pedal 120 is unfolded, the first limit member 160 abuts against the lower plate 320 and is located on the same horizontal plane, which can effectively limit the pedal 120 from continuing to rotate downward, thereby ensuring the stability of the unfolding of the pedal 120.

[0063] It is understandable that in order to enhance the strength and load-bearing capacity of the pedal 120 and improve the stability of the pedal 120, when there is a first limit member 160, some reinforcing ribs can be welded on both sides of the first limit member 160, and when there are two first limit members 160, some reinforcing ribs can be welded between the two first limit members 160 to improve the load-bearing capacity of the pedal 120 and extend the service life of the pedal 120.

[0064] Optionally, a second limit member can be set at both ends of the pedal 120 in the length direction. The second limit member is fixedly connected to the lower plate 320 and is located in the accommodating space formed by the upper plate 310 and the lower plate 320. The setting of the second limit member can prevent the pedal 120 from moving after it is folded up during the driving of the bus, affecting the stability of the connection of the pin shaft 150.

[0065] In a feasible implementation, a first slide is provided on the pedal 120, and the first slide is arranged on the side of the pedal 120 facing the safety door 200. The guide rod 110 is connected to the first slide through a first slider, and the guide rod 110 is rotatably connected to the first slider.

[0066] Among them, by setting the first slideway, the end of the first rod of the guide rod 110 away from the second rod can be set in the first slideway through the first slider, so as to realize the movement of the guide rod 110 on the pedal 120, and then realize the thrust and pull of the safety door 200 are applied to the pedal 120 through the guide rod 110, so as to realize the deployment and folding of the pedal 120. It can be understood that the first rod needs to rotate in the first slider to realize the smooth movement of the guide rod 110 on the pedal 120. The rotation connection can be set in a spherical groove in the first slider, and then the first rod is set in the spherical groove through the hinge ball to realize the rotation of the first rod in the first slider.

[0067] It should be noted that a ball bearing may be provided on one side of the first slideway facing the first slideway, which can reduce friction and improve the smoothness of movement of the first slider, thereby ensuring the smoothness of unfolding and folding of the pedal 120 and improving the working efficiency of the pedal mechanism 100.

[0068] Figure 5 It is a schematic diagram of a guide rod and a first support plate according to an embodiment of the utility model.

[0069] In a possible implementation, Figure 5 As shown, the pedal 120 is provided with a second slideway. When the safety door 200 is opened, the second slideway is arranged on the side of the pedal 120 facing the ground or away from the ground;

[0070] The first support plate 170 is arranged in a U shape, one end of the first support plate 170 is connected to the guide rod 110, and the other end of the first support plate 170 is arranged in the second slideway through the second sliding block.

[0071] Among them, the first support plate 170 and the second support plate 180 have the same principle, the first support plate 170 includes two parallel plates and a vertical plate connecting the two parallel plates, the first rod of the guide rod 110 passes through one of the parallel plates, and the first rod rotates in the parallel plate, the other parallel plate is arranged in the second slideway through the second slider, the second slideway is located on the upper plane or the lower plane of the pedal 120 when unfolded, and is arranged close to the first slideway, and the second slideway avoids the first limiter 160. It can be understood that the movement of the guide rod 110 on the pedal 120 is realized through the two slideways, the stability and reliability of the movement of the guide rod 110 are improved, and then the stability and reliability of the unfolding and folding of the pedal 120 are ensured.

[0072] It should be noted that the first rod is hinged to a parallel plate of the first support plate 170 by providing an annular groove on the first rod, providing a through hole on the parallel plate, and the annular groove is engaged with the through hole, that is, the diameter of the through hole is smaller than the outer diameter of the first rod and the diameter of the through hole is larger than the inner diameter of the annular groove, so that the first rod and the first support plate 170 can be hinged. A miniature bearing can also be provided between the through hole and the annular groove, such a provision can make the rotation of the first rod more stable, the transmission of the thrust and pull of the safety door 200 more rapid and accurate, and improve the efficiency of the deployment and retraction of the pedal 120. The hinge of the first rod and the first support plate 170 can also be other hinge forms that can be thought of in the art, such as providing a ball head at the end of the first rod away from the second rod, and providing a spherical groove on a parallel plate of the first support plate 170, which can also achieve the hinge of the first rod and the first support plate 170, which will not be repeated here.

[0073] In a feasible implementation manner, when the safety door 200 is closed, an anti-skid plate is provided on the side of the pedal 120 facing the vehicle body 300 .

[0074] Among them, when the safety door 200 is closed, an anti-skid plate is provided on the side of the pedal 120 facing the vehicle body 300, that is, when the safety door 200 is opened, an anti-skid plate is provided on the upward side of the pedal 120. Such a setting can ensure the safety of passengers stepping on it and reduce the possibility of passengers spraining and slipping.

[0075] In a feasible implementation manner, a warning paint layer is provided on the side of the anti-skid plate facing away from the pedal 120 .

[0076] Among them, a layer of warning paint is usually provided on the anti-skid plate to help passengers clearly know the location of the pedal. The warning paint layer can be any conspicuous color such as yellow, red, etc., and there is no limitation here.

[0077] It should be noted that the material of the stepping mechanism 100 is a metal plate, which can be coated with a layer of anti-rust paint to extend the service life of the stepping mechanism 100.

[0078] Another embodiment of the present invention provides a passenger car, which includes the above-mentioned stepping mechanism 100 for a safety door.

[0079] Among them, the stepping mechanism 100 is located between the safety door 200 and the vehicle body 300. When the safety door 200 is opened, the pulling force is transmitted to the pedal 120 through the guide rod 110 to realize the deployment of the pedal 120. Similarly, when the safety door 200 is closed, the thrust is transmitted to the pedal 120 through the guide rod 110 to realize the folding of the pedal 120, shortening the height of the vehicle body 300 corresponding to the safety door 200 from the ground, making it convenient for passengers to quickly leave the accident vehicle, improving the escape efficiency, and greatly reducing the safety hazards of passengers falling and spraining.
