In the present disclosure, unless otherwise indicated, terms of orientation such as "upper", "lower", "front", "rear" are used with respect to the front and rear of the vehicle, such as the front of the vehicle head position, the rear of the vehicle tail position, the upper roof position, and the lower floor position. The terms "first," "second," and the like, as used herein, do not denote any order or importance, but rather are used to distinguish one element from another. In addition, when the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements unless otherwise indicated.

As shown in fig. 1 to 5, the present disclosure provides a vehicle including a stepping mechanism for mounting at a step 7 inside a door. The step 7 is, for example, a VAN type having a higher vehicle floor 8 position, and is a step below the vehicle floor provided at a door opening position for convenience of passengers to get on and off the vehicle. The stepping mechanism of the present disclosure includes a first pedal 1, a second pedal 2, and a third pedal 3. The first pedal 1 is arranged above the pedal step surface in a lifting manner through a lifting structure, and the first pedal 1 and the second pedal 2 and the third pedal 3 are respectively connected through a folding structure. In the process of vehicle running, the second pedal 2 and the third pedal 3 are folded to the upper side of the first pedal 1 through the folding structure, and the first pedal 1 is lifted to a proper position through the lifting structure, so that the floor in the area of the pedal step 7 is compensated, the support is provided for the feet of the passengers sitting in the first row of seats behind the pedal step 7, the designer does not need to cancel the seats in the first row behind the pedal step 7 because of taking comfort and safety of the passengers into consideration, and the space in the vehicle can be fully utilized. And the second pedal 2 and the third pedal 3 are both positioned above the first pedal 1 in the folded position, so that the stepping mechanism is more compact as a whole, and occupied space inside the vehicle body is saved.

When the passenger is parked, the lifting structure is lowered, and the second step 2 is rotated outwardly to a position lower than the first step 1 by the folding structure, so that the second step 2 is formed as a secondary step for assisting the passenger in getting on and off the vehicle. The secondary step is relative to the step 7, and although the step 7 is provided, the step 7 is still high relative to a specific group of people, such as children and elderly people. When the second pedal 2 rotates to a position lower than the pedal step 7, a pedal part for assisting in getting on and off the vehicle can be formed between the ground and the pedal step 7, namely, a second-stage pedal is formed, and compared with the mode of getting on and off the vehicle directly through the pedal step 7, the vehicle with the pedal mechanism can be used for providing convenience for different people.

In addition, the stepping mechanism is arranged at the pedal step 7 on the inner side of the vehicle door, namely, the stepping mechanism is directly arranged on the pedal step surface of the vehicle, the vehicle body can be realized without great transformation, and the installation and the use are more convenient. In addition, the second pedal 2 and the third pedal 3 of the present disclosure can rotate to the upper side of the first pedal 1 in the folded position, that is, in the running process of the vehicle, the stepping mechanism can be completely hidden inside the vehicle body, and compared with the mode of being installed at the bottom of the chassis of the vehicle in the related art, the passing performance of the vehicle and the aesthetic property of the whole vehicle are not affected.

The present disclosure is not limited to the specific implementation of the folding structure, and any structure or method capable of folding the second pedal 2 and the third pedal 3 above the first pedal 1 or rotating the second pedal 2 outward to a position lower than the first pedal 1 may be applied to the present disclosure. According to one embodiment of the present disclosure, as shown in FIG. 1, the vehicle stepping mechanism further includes a first gear 41 and a second gear 42. Wherein the first gear 41 is fixedly installed at the front and rear end portions of the first pedal 1; the second gear 42 is fixedly installed at the front and rear end portions of the third pedal 3, and the second gear 42 is meshed with the first gear 41 and is rotatable about the axis of the first gear 41 to drive the third pedal 3 to rotate about the first pedal 1. With continued reference to fig. 3, the second step 2 and the third step are both in a folded position, the second step 2 being folded over the first step 1, and the third step 3 being folded over the second step 2. During the process of unfolding the second pedal 2 and the third pedal 3, the second gear 42 drives the third pedal 3 to rotate in the vehicle-outside direction up to the position shown in fig. 4.

To further expand the second pedal 2 to a position suitable for being stepped on, as shown in fig. 4 and 5, the vehicle stepping mechanism of the present disclosure further includes a first telescopic rod 43, both ends (fixed end and telescopic end) of the first telescopic rod 43 being connected to the third pedal 3 and the second pedal 2, respectively. After the second step 2 and the third step 3 are rotated to the outside of the vehicle body by the first gear 41 and the second gear 42, as shown in fig. 4, the second step 2 and the third step 3 are still folded together and are in a state of being perpendicular to the ground. The telescopic end of the first telescopic rod 43 extends outwards to drive the second pedal 2 to turn outwards until the second pedal 2 is in the horizontal position. As shown in fig. 5, the first step 1, the second step 2, and the third step 3 may be formed in a Z-shaped structure when unfolded, i.e., the second step 2 is substantially parallel to the first step 1, so that passengers can smoothly get on and off the vehicle through the second step 2 and the first step 1.

As shown in fig. 5 and 6, the second pedal 2 is provided with an elongated chute 31, specifically, the elongated chute 31 is provided on the front and rear ends of the second pedal 2, so that the first telescopic rod 43 can slide in the elongated chute 31 in the process that the first telescopic rod 43 extends to drive the second pedal 2 to turn outwards. Further, the length of the chute 31 is configured such that the second step 2 is in a horizontal position when the second step 2 is in the deployed state. Since the extension of the first telescopic link 45 is limited by the elongated chute 31, it is ensured that the second pedal 2 does not excessively rotate outward to be in an inclined position which is unfavorable for stepping, and furthermore, the problem of the extension amount of the first telescopic link 43 is not considered, and the second pedal 2 can be in a horizontal position as long as it is fully extended.

According to other embodiments of the present disclosure, in order to achieve folding or unfolding of the second pedal 2, besides the above-mentioned manner of the first gear 41 and the second gear 42 that are meshed with each other, a manner of setting rotating shafts on the second pedal 2 and the third pedal 3 respectively may be adopted, and rocker arms are respectively disposed at front and rear ends of the rotating shafts and connected with a driving motor, so that the rocker arms are driven to swing by the driving motor, and further the second pedal 2 and the third pedal rotate around their respective rotating shafts, so that folding and unfolding of the second pedal 2 and the third pedal 3 can be achieved as well.

As shown in fig. 5, a hinge structure 6 may be provided between the second step 2 and the third step 3. The connection stability between the second pedal 2 and the third pedal 3 can be enhanced by the hinge structure in a rotating connection manner, and the mutual rotation between the second pedal 2 and the third pedal 3 is not hindered to be unfolded.

The lifting structure of the present disclosure may be configured as a scissor structure including a first support bar 51, a second support bar 52, and a second telescopic bar 53. Both ends of the second telescopic link 53 are connected to the first support link 51 and the second support link 52, respectively. As shown in fig. 1, for example, a fixed end of the second telescopic link 53 is connected to the first support link 51, and a telescopic end is connected to the second support link 52. When the second telescopic rod 53 is extended, the scissor structure is pushed to be opened outwards to enable the first pedal 1 to be lifted upwards, and when the second telescopic rod 53 is retracted, the scissor structure is pulled to be contracted inwards to enable the first pedal 1 to be lowered downwards. According to other embodiments of the present disclosure, a vertically disposed telescopic cylinder may also be used to directly drive the first pedal 1 to rise or fall downward.

With continued reference to fig. 1, the lifting structure further includes a slide rail 54 for mounting on a tread surface, the second support bar 52 is slidably coupled to the slide rail 54, and the first support bar 51 is rotatably coupled to the tread surface. The slide rail 54 may be fixed to the step surface by a fastener, and the second support rod 52 may slide in the slide rail 54 as the second telescopic rod 53 is extended or retracted, so as to achieve the opening or closing of the scissor structure. Specifically, the second support rod 52 may be provided with a slider, where the sliding rail 54 is configured as a slot with an opening that is contracted inward, and the slider is slidably inserted into the sliding rail 54 back and forth, and is slidable relative to the length direction of the sliding rail 54 without being pulled out.

As shown in fig. 2, the stepping mechanism of the present disclosure is configured to: when the lifting mechanism is in the raised position and the folding structure is in the folded position, the upper surface of the third pedal 3 is flush with the floor 8 of the vehicle, i.e. when the first pedal 1 is in the raised state, the upper surface of the third pedal 3 folded over the first pedal 1 and the second pedal 2 acts as a compensation for the area of the foot step 7 to support the feet of the passengers. The upper surface of the third pedal 3 is flush with the vehicle floor 8, which is more aesthetically pleasing as a whole. It will be appreciated that the position of the upper surface of the third pedal 3 relative to the vehicle floor 8 may also be adjusted appropriately according to the actual situation, for example different heights of different passengers.

According to one embodiment of the present disclosure, the vehicle further comprises a sensor and a controller. The sensor is used to acquire door position information of the vehicle, such as whether the door is in an open or closed state. The sensor may, for example, employ a position sensor that senses the relative position with the door to determine whether the door is open or closed. The controller is respectively connected with the sensor and the stepping mechanism and used for controlling the action of the stepping mechanism according to the acquired vehicle door position information. Specifically, when the door is opened, the first pedal 1 is controlled to fall and the second pedal 2 is controlled to rotate to a position lower than the first pedal 1; when the vehicle door is ready to be closed, the second pedal 2 and the third pedal 3 are controlled to be folded above the first pedal 1, and after the vehicle door is closed, the first pedal 1 is controlled to be lifted. The controller for controlling the stepping mechanism according to the signal of the sensor in the present disclosure may be integrated in the ECU of the whole vehicle, or may also be separately provided to be connected to the sensor point, which is not limited in the present disclosure.

A fully implementable vehicle stepper control system in accordance with the present disclosure is now illustratively described with reference to fig. 2-5. During driving, the second telescopic rod 53 is extended to lift the lifting structure to the position shown in fig. 2, and the upper surface of the third pedal 3 is flush with the vehicle floor 8 for the passenger to tread. When the vehicle is stopped and the door is opened, the sensor on the door transmits a signal to the controller, which controls the first pedal 1 to be lowered to the lowest position as shown in fig. 3. The driving motor drives the second gear 42 to rotate about the axis of the first gear 41 to drive the third pedal 3 to rotate about the first pedal 1 to the outside of the vehicle body, up to the position where the second pedal 2 and the third pedal 3 are perpendicular to the ground as shown in fig. 4. Then the first telescopic rod 43 stretches out to drive the second pedal 2 to turn outwards until the first pedal 1, the second pedal 2 and the third pedal 3 are unfolded to be in a Z-shaped structure as shown in fig. 5, wherein the second pedal 2 is in a horizontal position, the first telescopic rod 43 reaches the longest state at this time, the telescopic end of the first telescopic rod 43 is located at the extreme end of the long-strip-shaped chute 31 on the third pedal 3, and the first telescopic rod 43 is locked. The passenger can get on or off the vehicle by stepping on the second pedal 1 and the second pedal 2. When the vehicle door is ready to be closed, the first telescopic rod 43 is retracted, the second pedal 2 is driven to inwards overturn to the position shown in fig. 4, and the driving motor drives the second gear 42 to rotate around the axis of the first gear 41, so that the third pedal 3 is driven to rotate around the first pedal 1 to the position shown in fig. 3. When the door is closed, the sensor transmits a signal to the controller, and the lifting structure lifts the first pedal 1 to the position shown in fig. 2.
