[0020] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0021] Currently, MPV models typically have electric steps installed at the door positions, with the extension and retraction of the electric steps driven by a motor. However, existing electric steps have complex structures and high costs, and the motor installation also occupies vehicle space, which is not conducive to the overall design and space utilization of the vehicle.

[0022] The following is for reference. Figures 1-4 A door assembly according to an embodiment of the present invention is described.

[0023] The door assembly 1 according to this utility model includes a door 10, a pedal 11, and a linkage 12. The door 10 is slidably disposed on the vehicle body and has a range of motion in the width direction and the length direction of the vehicle body, respectively. The pedal 11 is connected to the vehicle body and has a range of motion in the width direction and the length direction of the vehicle body. A guide rail 13 is formed on the pedal 11. The linkage 12 is disposed on the door 10 and is adapted to cooperate with the guide rail 13. During the active movement of the door 10, the linkage 12 drives the pedal 11 to move in the width direction of the vehicle. The linkage 12 is adapted to slide along the guide rail 13 in the length direction of the vehicle.

[0024] The vehicle door assembly 1 according to this utility model includes a door 10, a step 11, and a linkage 12. The door 10 is slidably mounted on the vehicle body and has a range of motion in both the width and length directions of the vehicle body, meaning it can move in both directions during opening and closing. The step 11 is connected to the vehicle body and has a guide rail 13. The step 11 also has a range of motion in the width direction of the vehicle body, allowing it to selectively expand or retract. When the step 11 is expanded, it lowers the entry / exit height, improving ease of entry and exit. The linkage 12 is mounted on the door 10. It is also suitable for cooperating with the guide rail 13 to drive the pedal 11 to move. Specifically, the linkage 12 is connected to the door 10. During the opening or closing of the door 10, the linkage 12 can move with the door 10 in the width and length directions of the vehicle body. At the same time, since the linkage 12 cooperates with the guide rail 13 on the pedal 11, the linkage 12 will move along the guide rail 13. At this time, there is an interaction force between the linkage 12 and the guide rail 13. Since the linkage 12 is fixed to the door 10 and the pedal 11 is movably connected to the vehicle body, the linkage 12 will drive the entire pedal 11 to move through the guide rail 13, so as to realize the opening or closing of the pedal 11.

[0025] The unfolding and retracting process of the pedal 11 can be simply understood as follows: During the opening of the door 10, the door 10 first moves in the width direction of the vehicle body. At this time, the linkage 12 drives the pedal 11 to move in the width direction of the vehicle body towards the opening direction of the door 10, so that the pedal 11 unfolds to form a stepping area for the user to get in and out of the vehicle. When the door 10 moves open in the front-rear direction of the vehicle body, the linkage 12 can drive the pedal 11 to move in the length direction of the vehicle body to adjust to the optimal alighting position. Alternatively, the guide rail 13 can extend along the length of the vehicle body, thereby enabling the linkage... The linkage 12 moves along the guide rail 13 following the door 10, and does not cause the pedal 11 to move. During the closing process of the door 10, the door 10 first moves in the length direction of the vehicle body. At this time, the linkage 12 slides along the guide rail and can cause the pedal 11 to move to a retractable position. Alternatively, the guide rail 13 can extend in the length of the vehicle body, and the linkage 12 will not cause the pedal 11 to move. When the door 10 closes in the width direction of the vehicle body, the linkage 12 will exert a force on the guide rail 13 in the width direction of the vehicle body and drive the pedal 11 to retract to the vehicle body.

[0026] According to the present invention, the door assembly 1 is provided with a pedal 11 and a linkage 12. The pedal 11 is provided with a guide rail 13. The linkage 12 is provided on the door 10 and moves with the door 10. Through the cooperation of the linkage 12 and the guide rail 13, the pedal 11 can be expanded and retracted as the door 10 is opened and closed. The whole process does not require an additional motor drive. It cleverly utilizes the original sliding mechanism of the door 10 and realizes the function of the pedal 11 through simple mechanical linkage. It simplifies the side step structure of the vehicle body, reduces costs, and improves the design flexibility of the vehicle interior space.

[0027] According to one embodiment of the present invention, the guide rail 13 includes: a first rail 131 and a second rail 132. The first rail 131 extends obliquely along the width and length of the vehicle body, and the second rail 132 extends along the length of the vehicle body. The first rail 131 and the second rail 132 are connected to each other. The linkage 12 drives the pedal 11 to unfold in the width direction within the first rail 131.

[0028] like Figures 1-4As shown, the guide rail 13 includes a first rail 131 and a second rail 132. The first rail 131 extends obliquely along the width and length of the vehicle body, while the second rail 132 extends directly along the length of the vehicle body. The linkage 12 can move on the first rail 131 and the second rail 132. When the door 10 is closed, the linkage 12 is located on the first rail 131; when the door 10 is open, the linkage 12 moves along the first rail 131. At this time, since the first rail 131 is oblique, the linkage 12 will generate an oblique force on the pedal 11. This force can be decomposed into two components in the width direction and the length direction of the vehicle body. The component in the width direction will drive the pedal 11 to unfold in the width direction, forming a stepping area for the user to get in and out of the vehicle. When the linkage 12 moves to the connection point between the first track 131 and the second track 132, the door 10 completes the opening process in the width direction. At this time, the door 10 can continue to open in the length direction of the vehicle body. The linkage 12 will enter the second track 132 and slide along the second track 132 in the length direction of the vehicle body. At this time, the force exerted by the linkage 12 on the pedal 11 in the width direction of the vehicle body disappears or decreases, and the pedal 11 will remain at the current width position and will not continue to unfold. When the door 10 closes, the linkage 12 slides in the opposite direction along the second track 132 to the first track 131, and while moving in the first track 131, it simultaneously drives the pedal 11 to retract in the width direction of the vehicle body until the door 10 is completely closed and the pedal 11 is completely retracted to the bottom of the vehicle body. The whole process is smooth and does not require additional power.

[0029] According to one embodiment of the present invention, the connection between the first track 131 and the second track 132 is rounded. This rounded transition design makes the connection between the first track 131 and the second track 132 more seamless. When the linkage 12 moves between the first track 131 and the second track 132, it can pass through the connection more smoothly, avoiding jamming or impact caused by abrupt changes in track shape. This improves the smoothness of the pedal 11's unfolding and retracting, and reduces wear between the linkage 12 and the guide track 13, extending their service life. This further enhances the reliability and durability of the entire door assembly 1.

[0030] According to one embodiment of the present invention, the door assembly 1 further includes a linkage assembly 14, which is disposed on the vehicle body and used to support the pedal 11. The linkage assembly 14 is adapted to drive the pedal 11 to unfold in the width direction. The linkage assembly 14 is a structure in the door assembly 1 used to support the pedal 11. When the pedal 11 needs to be unfolded, the linkage assembly 14 can unfold with the movement of the pedal 11, providing stable support for the pedal 11, so that the pedal 11 has sufficient load-bearing capacity, ensuring that the user can get in and out of the vehicle safely and comfortably. Specifically, the linkage assembly 14 can form a movable support structure by hinged connection with the vehicle body and the pedal 11. When the pedal 11 unfolds in the width direction of the vehicle body, the linkage assembly 14 also unfolds, providing reliable support for the pedal 11 and improving the reliability of the door assembly 1. During the retraction of the pedal 11, the linkage assembly 14 can retract accordingly without occupying additional space, thereby ensuring the overall compactness and aesthetics of the door assembly 1.

[0031] According to one embodiment of this utility model, the linkage assembly 14 is constructed in multiple sets, each set of linkage assembly 14 being rotatable relative to the vehicle body. This rotatability ensures that the linkage assembly 14 can more flexibly follow the movement of the pedal 11 during its unfolding and retraction. The multiple sets of linkage assemblies 14 improve the load-bearing capacity of the pedal 11. When the pedal 11 unfolds, the multiple sets of linkage assemblies 14 work together, unfolding according to a predetermined trajectory and angle, providing uniform and stable support for the pedal 11, thus improving the safety of users getting in and out of the vehicle. When the pedal 11 retracts, the multiple sets of linkage assemblies 14 can rotate relative to the vehicle body, smoothly retracting to the bottom of the vehicle body without interfering with other components, ensuring the overall compactness of the door assembly 1, and also facilitating the overall design and space utilization of the vehicle.

[0032] According to one embodiment of the present invention, at least one linkage assembly 14 includes: a first linkage 141, wherein a plurality of first linkages 141 are configured to be arranged parallel to each other, one end of each first linkage 141 is hinged to the vehicle body, and the other end of each first linkage 141 is hinged to the pedal 11, and the first linkage 141 rotates in a plane in the length and width directions. Figures 1-4As shown, the pedal 11 has a first link 141 disposed in a link assembly 14 on at least one side of the vehicle body length direction. Multiple first links 141 are constructed to be arranged parallel to each other, and these multiple first links 141 can rotate synchronously to support the pedal 11. This not only enhances the overall structural strength of the link assembly 14 but also improves the stability of the pedal 11. One end of each first link 141 is hinged to the vehicle body, and the other end is hinged to the pedal 11, allowing the first link 141 to rotate freely in the planes along its length and width directions. When the pedal 11 is extended, the first link 141 rotates and extends with the pedal 11, providing stable support for the pedal 11; when the pedal 11 is retracted, the first link 141 rotates and retracts accordingly, without occupying additional space.

[0033] According to one embodiment of the present invention, at least another linkage assembly 14 includes: a second linkage 142 and a third linkage 143, one end of the second linkage 142 being hinged to the vehicle body, and the second linkage 142 rotating in a plane in the length and width directions; one end of the third linkage 143 being hinged to the second linkage 142, and the other end of the third linkage 143 being hinged to the pedal 11, and the third linkage 143 rotating in a plane in the length and width directions. Figures 1-4 As shown, another link assembly 14 is provided in the middle region of the pedal 11 along the length of the vehicle body. This link assembly 14 is formed by hinged connection of a second link 142 and a third link 143. The second link 142 is hinged to the vehicle body at one end and can rotate in the plane in the length and width directions. The third link 143 is hinged to the second link 142 at one end and to the pedal 11 at the other end, and can also rotate in the plane in the length and width directions. The second link 142 and the third link 143 cooperate to form a double-link structure, which further enhances the stability of the pedal 11 during the unfolding and retraction process. When the pedal 11 unfolds, the second link 142 and the third link 143 rotate separately and work together to provide more stable support for the pedal 11, ensuring that the pedal 11 can be smoothly unfolded to the predetermined position for easy access for users to get on and off the vehicle. When the pedal 11 retracts, the second link 142 and the third link 143 rotate separately again to smoothly retract the pedal 11 to the bottom of the vehicle body. The whole process is compact and orderly, and will not affect other parts of the vehicle. It also improves the overall reliability and durability of the door assembly 1.

[0034] Furthermore, since the first link 141 and the second link 142 are hinged to each other, relative rotation between the first link 141 and the second link 142 is possible. This avoids mechanical dead points in the link assembly 14 during the unfolding and retraction of the pedal 11, further improving the flexibility and smoothness of the movement of the link assembly 14. This ensures that the pedal 11 remains stable during unfolding and retraction, without any jamming or shaking due to mechanical dead points, providing users with a more comfortable and safer experience when getting on and off the vehicle.

[0035] According to one embodiment of the present invention, the linkage assembly 14 further includes a bottom guard plate 15, which is disposed on the vehicle body and located at the bottom of the linkage assembly 14. When the pedal 11 is retracted, the bottom guard plate 15 is disposed directly opposite the linkage assembly 14 in the height direction at least a portion thereof.

[0036] When the pedal 11 is retracted, the underbody protection plate 15 is positioned at least partially opposite the connecting rod assembly 14 in the height direction. That is, the underbody protection plate 15 is located at the bottom of the connecting rod assembly 14 and effectively protects it. During vehicle operation, the underbody protection plate 15 can block impacts from stones, debris, and other objects on the road surface, preventing damage to the connecting rod assembly 14 due to external impacts and thus extending its service life. The design of the underbody protection plate 15 makes efficient use of the space under the vehicle body, resulting in a more compact structure for the entire door assembly 1. When the pedal 11 is retracted, the underbody protection plate 15 can partially cover the bottom of the connecting rod assembly 14, preventing dust and dirt from entering the moving parts of the connecting rod assembly 14. This reduces problems such as impaired movement or accelerated wear of the connecting rod assembly 14 caused by dust and dirt accumulation, further ensuring the normal operation and reliability of the door assembly 1.

[0037] According to one embodiment of the present invention, a baffle plate 16 extending towards the bottom is formed on the outer edge of the pedal 11. The baffle plate 16 is at least partially directly opposite the connecting rod assembly 14 in the horizontal direction. The baffle plate 16 is disposed on the outer edge of the pedal 11 and extends towards the bottom, and is at least partially directly opposite the connecting rod assembly 14 in the horizontal direction. That is, the baffle plate 16 extends in the height direction of the vehicle body and covers at least a portion of the connecting rod assembly 14 in the width direction of the vehicle body. This allows the baffle plate 16 to protect the connecting rod assembly 14 from the horizontal direction (mainly the width direction) of the vehicle body, improving the reliability of the connecting rod assembly 14. Specifically, during vehicle operation, the baffle plate 16 can effectively block mud, sand, and other debris splashed from the road surface, preventing these debris from directly impacting the connecting rod assembly 14, reducing the probability of damage to the connecting rod assembly 14 due to external force erosion, extending the service life of the connecting rod assembly 14, and reducing maintenance costs. Meanwhile, during the unfolding and retraction of the pedal 11, the relative positional relationship between the cover plate 16 and the linkage assembly 14 will not interfere with the normal movement of the linkage assembly 14, ensuring the smoothness of the unfolding and retraction of the pedal 11 and ensuring that the user can get on and off the vehicle smoothly and safely.

[0038] Furthermore, the shield 16 and the underbody protection plate 15 work together to form a dual protection mechanism, providing comprehensive protection for the linkage assembly 14 from multiple directions. The underbody protection plate 15 primarily protects against impacts from stones and debris, as well as dust and mud accumulation, that may occur from the bottom of the vehicle. The shield 16, on the other hand, focuses on blocking horizontal impacts from mud, sand, and other debris splashed up from the vehicle body, especially in the width direction, from affecting the linkage assembly 14. The synergistic effect of the shield 16 and the underbody protection plate 15 significantly improves the reliability of the linkage assembly 14 under various complex road conditions, reduces damage to the linkage assembly 14 caused by external factors, and thus lowers the maintenance frequency and cost of the door assembly 1. This dual protection mechanism ensures that the linkage assembly 14 maintains a stable and smooth movement during the unfolding and retraction of the pedal 11, providing users with a more reliable and comfortable entry and exit experience, and further enhancing the overall performance and quality of the entire door assembly 1.
