Description

Technical Field

[0001] This application relates to the field of vehicle design and manufacturing technology, and in particular to a door sill assembly and a vehicle equipped with the door sill assembly. Background Technology

[0002] In vehicle body structure, the sill beam is not only an important path for transmitting collision forces, but also sometimes needs to provide space for the installation and movement of pedals. Related technologies typically create a through-beam in the side area of ​​the sill beam by cutting or grooving to accommodate the pedal; or the sill beam is designed as a discontinuous break, with a gap at the break point for pedal installation. These processing methods substantially damage the structural integrity and continuity of the beam itself, significantly weakening its bending and torsional stiffness and its ability to transmit collision loads. This leads to a persistent technical conflict when installing pedal space on the sill beam, where the beam's load-bearing capacity and accessory installation functionality cannot be reconciled. Specifically, this conflict manifests as follows: altering the continuous structure to provide installation space introduces weak points, making it difficult to meet increasingly stringent requirements for side-impact safety and vehicle body rigidity.

[0003] Therefore, how to ensure that the sill beam, as a load-bearing beam, provides space for the installation of the pedal without affecting its own load-bearing performance is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] In view of this, the purpose of this application is to provide a sill assembly and vehicle that can provide space for installing pedals while ensuring that the sill beam, as a load-bearing beam, does not affect its load-bearing performance.

[0005] To achieve the above objectives, this application provides the following technical solution: A door sill assembly, comprising: A foot pedal is used to provide foot support for passengers and / or goods getting on and off the vehicle; The door sill beam extends continuously along the side of the vehicle body; A pedal mounting beam is located above and connected to the sill beam. The pedal mounting beam has an opening for providing movement space for the pedal, allowing the pedal to extend out of the vehicle through the opening and retract into the vehicle through the opening.

[0006] Optionally, in the above-described sill assembly, the pedal mounting beam is detachably connected to the sill beam.

[0007] Optionally, in the above-described sill assembly, the pedal mounting beam comprises an aluminum extrusion profile; and / or, the sill beam comprises an aluminum extrusion profile.

[0008] Optionally, in the above-mentioned sill assembly, the sill beam is provided with a plurality of first cavities arranged side by side along its own width direction; and / or, the sill beam is provided with a plurality of first cavities arranged side by side along its own thickness direction; and / or, the pedal mounting beam is provided with a plurality of second cavities arranged side by side along its own width direction; and / or, the pedal mounting beam is provided with a plurality of second cavities arranged side by side along its own thickness direction.

[0009] Optionally, in the above-mentioned door sill assembly, the pedal mounting beam includes a first connecting portion, a clearance portion, and a second connecting portion connected sequentially along the side of the vehicle body, wherein: The bottom surface of the clearance portion and the top surface of the sill beam have a preset gap greater than zero, forming the opening; The top surface of the first connecting part is connected to the top surface of the clearance part to form a continuous top surface; the bottom surface of the first connecting part is closer to the sill beam than the bottom surface of the clearance part, and the bottom surface of the first connecting part is connected to the top surface of the sill beam. The top surface of the second connecting part is connected to the top surface of the avoidance part to form a continuous top surface; the bottom surface of the second connecting part is closer to the sill beam than the bottom surface of the avoidance part, and the bottom surface of the second connecting part is connected to the top surface of the sill beam.

[0010] Optionally, in the above-mentioned sill assembly, the sill beam includes a lower continuous area and a raised area, and the lower continuous area includes a first section and a second section; The raised area protrudes above the first section and is integrally formed therewith; The pedal mounting beam is located above and fixedly connected to the second section.

[0011] Optionally, the above-mentioned threshold assembly further includes a connector, which includes a first connection area, a second connection area, and a third connection area: The first connecting area is used to overlap the side area of ​​the floor. The second connection area is located above and riveted to the pedal mounting beam; The third connecting area is located above the protruding area and is riveted to it.

[0012] A vehicle includes a floor and a sill assembly as described above, the floor being connected to the top surface of the pedal mounting beam in the sill assembly.

[0013] Optionally, the vehicle described above also includes a sliding connection assembly, the sliding connection assembly comprising: The first component unit is connected to the pedal and can move with the pedal to the outside of the opening or retract into the opening; The second component unit is located below the first component unit; and, in a direction perpendicular to the side direction of the vehicle body, the second component unit slides in conjunction with the first component unit.

[0014] Optionally, the vehicle described above also includes a battery pack, with the pedal retracted into the opening located between the floor and the battery pack.

[0015] As can be seen from the above technical solutions, in the sill assembly and vehicle provided by this application, the sill beam and pedal mounting beam are independent components, which together with the pedal constitute the sill assembly. In this sill assembly, the opening in the pedal mounting beam provides the necessary space for the pedal to extend and retract. Therefore, the sill beam adopts an integral continuous structure without side cuts or openings. The sill beam does not need to be partially broken, cut off, or have gaps that damage its structural integrity to accommodate the pedal. It can maintain structural integrity in the force transmission direction as a load-bearing beam, providing reliable load-bearing performance for the vehicle. Thus, in the sill assembly and vehicle provided by this application, the sill beam, as one of the core structural components of the vehicle body, can successfully integrate the telescopic pedal through the pedal mounting beam without sacrificing its own load-bearing performance. This eliminates the structural weakening problem caused by slotting or cutting the beam on the side of the sill beam in traditional one-piece designs. Attached Figure Description

Detailed Implementation

[0031] In the design of vehicle side structures, retractable steps are typically integrated to facilitate passenger entry and exit. A common approach in related technologies is to directly place the step and the space required for its movement onto the sill beam, a major load-bearing component of the vehicle body. Specifically, this solution accommodates the retractable movement of the step by creating a notch in the sill beam or using a split structure. Its basic working principle is to utilize the existing space inside or outside the sill beam to form a step-accommodating cavity, thus providing a direct mounting position for the step in the lower part of the vehicle side panel. This design was widely used in the early days primarily because it integrated the step with the main body structure as a single unit, attempting to simplify the assembly process while providing direct and fixed support for the step.

[0032] However, this solution performs poorly when applied to scenarios with more stringent requirements for vehicle body structural integrity, especially when the sill beam needs to completely transfer loads during a side impact. A fundamental contradiction lies in the fact that this solution necessitates partially discontinuing or hollowing out the sill beam to accommodate the pedal. This inherent structural design inevitably weakens the continuity and integrity of the sill beam's cross-section, leading to a degradation in its impact resistance and torsional rigidity as the primary force transmission path of the vehicle body. Specifically, in a real side pole impact scenario, stress concentration occurs in the sill beam in the pedal area due to abrupt changes in cross-section, making it prone to severe local crushing or tearing. This increases the intrusion into the lower part of the passenger compartment, endangering occupant safety.

[0033] Through in-depth analysis, the inventors discovered that the root cause of the aforementioned contradiction lies in the fact that the relevant technical solutions strongly couple the two functions of "the sill beam as a safety load-bearing component" and "the shell providing space for pedal movement" onto the same basic component. Traditional integrated designs require the sill beam to maintain a continuous, closed load-bearing cross-section while simultaneously providing an open space for the pedal facing outwards. These two tasks are physically mutually exclusive. The resulting structural weakening, regardless of the reinforcement methods employed, is a process of breaking down the existing structure before rebuilding, ultimately failing to escape the original damage to the integrity of the core safety structure.

[0034] To overcome the aforementioned contradictions, this invention proposes a different technical approach. Its core concept lies in the physical decoupling of load-bearing function and spatial accommodation function. The opening for the retractable movement of the pedal is constructed on a pedal mounting beam independent of and connected above the sill beam, thereby allowing the sill beam itself to maintain a completely continuous extension along the side of the vehicle body. In other words, without compromising the continuity and integrity of the sill beam as the main structural load-bearing component, the movement space of the pedal is defined by an upper, independent beam, resolving the contradiction between opening arrangement and structural safety, and achieving complete structural unity between load-bearing performance and functional space.

[0035] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0036] Please see Figures 1 to 5This application provides a door sill assembly, which includes a door sill beam 3, a pedal mounting beam 4, and a pedal 5. In specific implementations, the pedal 5 can be a ramp pedal. Specifically: the door sill beam 3, as one of the main load-bearing beams of the vehicle body frame, extends continuously and uninterruptedly along the side of the vehicle body in the X direction, maintaining structural integrity in the force transmission direction. It does not require cutting holes or breaks on the side for mounting the pedal 5, and can bear the main loads from various conditions such as frontal collisions, side collisions, and roof crushing, forming a key force transmission path for passenger compartment safety protection. The pedal mounting beam 4 is located above the door sill beam 3 and is fixedly connected to it. The pedal mounting beam 4 has an opening 8 to provide movement space for the pedal 5, allowing the pedal 5 to extend out of the vehicle through the opening 8 and retract into the vehicle through the opening 8. The pedal 5 is configured to extend outward from the opening 8 to provide foot support when passengers and / or items get on and off the vehicle, and to retract into the vehicle through the opening 8 after use, thus not protruding from the side profile of the vehicle body, maintaining vehicle passability and meeting relevant regulatory requirements. It should be noted that the side direction X of the vehicle body mentioned in this application specifically refers to a direction parallel to the vehicle's front-to-back direction or left-to-right direction. In specific implementation, if the step 5 is installed on the left or right side of the vehicle body, then the side direction X of the vehicle body is parallel to the vehicle's front-to-back direction, and the continuous extension direction of the sill beam 3 is parallel to the vehicle's front-to-back direction; if the step 5 is installed on the rear side of the vehicle body, then the side direction X of the vehicle body is parallel to the vehicle's left-to-right direction, and the continuous extension direction of the sill beam 3 is parallel to the vehicle's left-to-right direction.

[0037] As can be seen, the sill assembly provided in this application is a split-type combined structure, with the sill beam 3 and the pedal mounting beam 4 being independent components. The opening 8 in the pedal mounting beam 4 provides the necessary space for the extension and retraction of the pedal 5. Therefore, the sill beam 3 adopts an integral continuous structure without side cuts or openings, eliminating the need for partial disconnection, removal, or creating gaps that compromise its structural integrity to accommodate the pedal 5. It can maintain structural integrity as a load-bearing beam in the force transmission direction, providing reliable load-bearing performance for the vehicle. Thus, the sill assembly provided in this application enables the sill beam 3, as one of the core structural components of the vehicle body, to successfully integrate the pedal 5, which meets regulatory requirements, without sacrificing its own load-bearing performance. This eliminates the structural weakening problem caused by the need for slotting or cutting the beam on the side of the sill beam in traditional one-piece designs.

[0038] Please see Figure 3 and Figure 4In some embodiments, the pedal mounting beam 4 and the sill beam 3 are detachably connected by fasteners 7. A detachable connection means that the connection is designed to allow for complete separation of the pedal mounting beam 4 and the sill beam 3 by loosening or removing the fasteners 7 without damaging their structural integrity. Specifically, the fasteners 7 can be bolts, studs, screws, or other common standard parts used in the art for detachable mechanical connections. When using fasteners 7 to connect the pedal mounting beam 4 and the sill beam 3, the pedal mounting beam 4 has through holes corresponding to the positions of the fasteners 7, and the sill beam 3 has threaded holes or through holes corresponding to the positions of the fasteners 7 to accommodate nuts. Tightening the fasteners 7 presses the pedal mounting beam 4 firmly against the top surface of at least a partial area of ​​the sill beam 3. At this time, the bottom panel of the pedal mounting beam 4 is in contact with the top panel of a partial section of the sill beam 3 and is fixedly connected by the fasteners 7. The head and tail of the fasteners 7 are located within the internal cavities of the pedal mounting beam 4 and the sill beam 3, and are not exposed outside the beams.

[0039] In some embodiments, the pedal mounting beam 4 and the sill beam 3 are not only arranged along the length direction of the sill beam with at least two fasteners 7 spaced apart, but also, along the width direction of the sill beam, the pedal mounting beam 4 and the sill beam 3 are arranged side-by-side with at least two sets of fasteners 7 spaced apart. However, this is not a limitation; in other embodiments, a fastener 7 may be provided at each end of the pedal mounting beam 4 or at the bottom near both ends. It should be noted that the length direction of the sill beam is the same as the length direction of the sill beam 3 and also the length direction of the pedal mounting beam 4; the width direction of the sill beam is the same as the width direction of the sill beam 3 and also the width direction of the pedal mounting beam 4. The length direction and width direction of the sill beam are perpendicular to each other and parallel to the center plane of the floor 1.

[0040] In some embodiments, the pedal mounting beam 4 is made of extruded aluminum profile, thereby providing sufficient rigidity and tread strength in the connection area between the sill beam 3 and the floor 1. Furthermore, in specific implementations, the sill beam 3 can also be made of extruded aluminum profile. Extruded aluminum profile refers to a long strip material with a continuous, complex cross-sectional profile, obtained by heating aluminum or aluminum alloy billets and then extruding them through a die with a specific cross-sectional shape. The cross-section of the extruded aluminum profile can be optimized and customized according to stress requirements, for example, by arranging reinforcing ribs in directions requiring high rigidity, thereby achieving high section modulus of bending and torsional stiffness at a lower weight. However, this is not the only option. In other embodiments, depending on the different emphases of cost, manufacturing process, and collision energy absorption strategies in the overall vehicle design, the pedal mounting beam 4 can also be welded from high-strength steel stampings or molded from fiber-reinforced composite materials. In this case, the pedal mounting beam 4, made of extruded aluminum profile, can withstand the repeated loads transmitted by passengers when stepping on it in the local area where the opening 8 is located without easily collapsing or undergoing plastic deformation. Because the cross-section of aluminum extruded profiles can be designed as a grid-like structure containing multiple closed or semi-closed cavities, this structure is lightweight while being highly efficient at resisting bending and localized compression perpendicular to its extension direction. In conjunction with this, the sill beam 3 is made of aluminum extruded profiles, which helps meet the vehicle's lightweight requirements. Furthermore, its uniform, high-strength, and predictable cross-sectional characteristics along its continuous extension length in the X direction along the vehicle's side ensure that its mechanical properties remain essentially consistent throughout the collision energy transfer path.

[0041] To achieve lightweight design while ensuring that the sill beam 3 and pedal mounting beam 4 have sufficient capacity to withstand impact energy and foot loads from multiple directions, the internal structure of these two beam components can be optimized. For example, please refer to... Figure 4The cross-sectional structure shown is implemented in a specific way in which the sill beam 3 has multiple first cavities 30 arranged side-by-side along its width direction. The width direction of the sill beam 3 is a horizontal direction perpendicular to the side direction X of the vehicle body. The multiple first cavities 30 arranged side-by-side along this direction means that a row of independent or partially connected hollow cavities separated by vertical or inclined stiffeners is formed inside the sill beam 3. These cavities are arranged side-by-side along the width direction, which greatly enhances the bending stiffness and energy absorption capacity of the sill beam 3 when subjected to lateral compressive loads from the outside of the vehicle body. This is because when a side collision occurs, the side-by-side cavity structure will crush in stages, absorbing a large amount of energy. At the same time, the internal partition structure will prevent the sill beam 3 from prematurely undergoing overall bending instability. Alternatively or additionally, the sill beam 3 has multiple first cavities 30 arranged side-by-side along its thickness direction. The thickness direction of the sill beam 3 is also the vehicle height direction. Multiple first cavities 30 are arranged side by side along the thickness direction inside the sill beam 3, which means that the interior of the sill beam 3 is divided by multiple partitions in the height direction, forming multiple cavities arranged vertically. This structure can effectively improve the vertical bending resistance and crush resistance of the sill beam 3 when subjected to stepping loads from above and supporting or lifting loads from below.

[0042] Similar structural optimization strategies also apply to the pedal mounting beam 4. Multiple second cavities 40 arranged side-by-side along its width direction can also be provided within the pedal mounting beam 4. The width direction of the pedal mounting beam 4 is the horizontal direction perpendicular to the vehicle side direction X. These multiple second cavities 40 arranged side-by-side along the width direction within the pedal mounting beam 4 can resist lateral bending and torsional deformation of the pedal mounting beam 4. Alternatively or additionally, multiple second cavities 40 arranged side-by-side along its thickness direction are provided within the pedal mounting beam 4. The thickness direction of the pedal mounting beam 4 is typically the vehicle height direction. The cavity structure arranged side-by-side along this direction allows the pedal mounting beam 4 to effectively resist the pressure exerted on the top surface of the pedal mounting beam 4 when stepped on by a passenger, preventing collapse of the top area of ​​the opening 8.

[0043] Please see Figure 2In some embodiments, the pedal mounting beam 4 is a U-shaped component that is inverted on the sill beam 3 with its opening facing downward, thereby forming an opening 8 that can be mounted on the pedal 5. Specifically, the pedal mounting beam 4 includes a first connecting part 41, a clearance part 42, and a second connecting part 43 connected sequentially along its length. The clearance part 42 has a preset gap greater than zero between its bottom surface and the top surface of the sill beam 3, forming an opening 8 to provide movement space for the pedal 5. The top surface of the first connecting part 41 is connected to the top surface of the clearance part 42 to form a continuous top surface. The bottom surface of the first connecting part 41 is closer to the sill beam 3 than the bottom surface of the clearance part 42, and the bottom surface of the first connecting part 41 is fixedly connected to the top surface of the sill beam 3 by fasteners 7. The top surface of the second connecting part 43 is connected to the top surface of the clearance part 42 to form a continuous top surface. The bottom surface of the second connecting part 43 is closer to the sill beam 3 than the bottom surface of the clearance part 42, and the bottom surface of the second connecting part 43 is fixedly connected to the top surface of the sill beam 3 by fasteners 7. In this application, the continuous top surface refers to the absence of out-of-plane misalignment or steps in the joint area, with a smooth transition of the top surface contour. As a result, the three parts, namely the first connecting part 41, the avoidance part 42, and the second connecting part 43, are structurally integrally formed, and the top of the entire pedal mounting beam 4 is a complete bearing surface.

[0044] Please see Figure 2 and Figure 4 In some examples, the clearance portion 42 has at least two second cavities 40 arranged side-by-side in a horizontal direction perpendicular to the side direction X of the vehicle body. The first connecting portion 41 and the second connecting portion 43 each have multiple second cavities 40, each second cavity 40 being a through groove extending along the side direction X of the vehicle body. Specifically, in the side direction X of the vehicle body, if the vertical height of the second cavity 40 in the first connecting portion 41 and the second connecting portion 43 corresponding to the opening 8 is 'a', and the vertical height of the second cavity 40 in the first connecting portion 41, the second connecting portion 43, and the clearance portion 42 located above the opening 8 is 'b', then b < a. Therefore, the cavity gap in the top region of the pedal mounting beam 4 is smaller, resulting in greater rigidity and support strength, better ability to withstand the stepping load from above, and less susceptibility to deformation.

[0045] Please see Figure 5 and Figure 6In some embodiments, the sill beam 3 includes a lower continuous region 31 and a raised region 32. In order to accommodate the installation of the pedal mounting beam 4, the lower continuous region 31 is conceptually divided into a first segment 311 and a second segment 312 in the extending direction. The lower continuous area 31 forms the basic structure of the sill beam 3. Its bottom area and basic cross-section, extending along the X direction of the vehicle body, remain unchanged, ensuring that the front and rear collision force transmission path of the entire vehicle is unobstructed. The raised area 32 protrudes above the first section 311 and is integrally formed with the first section 311. Integral forming means that the raised area 32 is not an independent part attached to the lower continuous area 31 by welding or fasteners, but is directly extruded during the manufacturing of the sill beam 3, for example in an aluminum extrusion die, by adjusting the die hole shape, to increase the cross-sectional profile in a local area. This significantly increases the local effective height and section modulus of the sill beam 3 within the first section 311 area. The top surface of the second section 312 serves as the mounting plane of the pedal mounting beam 4. It can generally be milled to form a flat surface (not cut or hollowed out) to provide a solid and accurate mounting reference surface for the pedal mounting beam 4, so that both connecting parts of the pedal mounting beam 4 can be flatly and securely connected to the second section 312 of the sill beam 3.

[0046] Further, please see Figure 2 , Figure 3 and Figure 7 In some embodiments, the threshold assembly further includes a connector 2, which is a sheet metal component comprising a first connecting area 21, a second connecting area 22, a third connecting area 23, and an inner panel area 24. Specifically, the first connecting area 21 is used to overlap the side area of ​​the floor 1, and in specific implementations, the first connecting area 21 can be located in the middle floor (i.e.,...). Figure 1 The floor 1) shown is below and welded or riveted to it; the second connecting area 22 is above the pedal mounting beam 4 and riveted to it; the third connecting area 23 is above the protruding area 32 of the sill beam 3 and riveted to it, and the third connecting area 23 is provided with an inner panel area 24 that bends upward relative to its riveting area. The inner panel area 24 is generally located inside the side panel of the vehicle body and can fit against the inner surface of the side panel of the vehicle body.

[0047] This application embodiment also provides a vehicle, which includes a floor 1 and the sill assembly described above. The floor 1 is connected to the top surface of the pedal mounting beam 4 in the sill assembly (e.g., riveted). In this sill assembly, the sill beam 3 and the pedal mounting beam 4 are independent components, forming a split-type combined structure sill assembly. The opening 8 of the pedal mounting beam 4 can provide the necessary space for the pedal 5 to extend and retract. Thus, while ensuring the structural integrity of the sill beam 3 and the continuity of the force transmission path, a reliable installation and movement space is created between the sill beam 3 and the floor (i.e., floor 1) in the upper part of the vehicle body, allowing the pedal 5 to be extended and retracted, thereby realizing the standard configuration of the pedal 5 on the entire vehicle.

[0048] In some embodiments, the pedal 5 in the sill assembly is mounted below the floor 1 via a sliding connection assembly 6. The sliding connection assembly 6 provides linear guidance and support for the pedal 5, allowing it to extend out of the opening 8 along a telescopic direction Y perpendicular to the vehicle side direction X, and retract into the opening 8 along the same telescopic direction Y. It should be noted that when the sill assembly is located on the left and / or right side of the vehicle, the vehicle side direction X is the vehicle's front-to-back direction and also the length direction of the sill beam 3, i.e., a straight line parallel to the length of the sill beam 3; the telescopic direction Y, perpendicular to the vehicle side direction X, is the vehicle's left-to-right direction and also the width direction of the sill beam 3, i.e., a straight line parallel to the width of the sill beam 3. When the sill assembly is located at the rear door of the vehicle, the vehicle side direction X is the vehicle's left-to-right direction and also the length direction of the sill beam 3, i.e., a straight line parallel to the length of the sill beam 3; the telescopic direction Y, perpendicular to the vehicle side direction X, is the vehicle's front-to-back direction and also the width direction of the sill beam 3, i.e., a straight line parallel to the width of the sill beam 3.

[0049] Please see Figures 8 to 13 In some embodiments, the sliding connection assembly 6 includes a first component unit 61 and a second component unit 62, wherein: the first component unit 61 is fixedly connected to the pedal 5 and can move with the pedal 5 to the outside of the opening 8 or retract into the opening 8; the second component unit 62 is located below the first component unit 61, and in a direction perpendicular to the vehicle side direction X, the second component unit 62 is slidably engaged with the first component unit 61. Either the second component unit 62 or the first component unit 61 is provided with a groove, and the other is provided with a slider adapted to the groove.

[0050] In some embodiments, the second component unit 62 is fixedly connected to the sill beam 3, thus serving as a basic fixing component to provide support and guidance for the first component unit 61 and the pedal 5 during sliding. In some embodiments, the second component unit 62 can also be slidably connected to the sill beam 3, so that the second component unit 62 can extend outside the vehicle relative to the sill beam 3 to a preset distance, providing a certain support base for the pedal 5 extending outside the vehicle. When it is necessary to pull out the pedal 5, the second component unit 62 first drives part of the pedal 5 to extend outside the vehicle, and then the sliding cooperation between the first component unit 61 and the second component unit 62 allows the pedal 5 to continue to extend outside the vehicle.

[0051] Specifically, please see Figure 12 and Figure 13 In some embodiments, a sliding connection assembly 6 can be provided on each side of the pedal 5. Each sliding connection assembly 6 has a first component unit 61 with a groove 60 on its side for mounting the pedal 5. Furthermore, the second component units 62 of the sliding connection assemblies 6 located on both sides of the pedal 5 are connected by at least two parallel beams to form a fixed frame structure. This allows the sliding connection assembly 6 to extend and retract within the opening 8, while the frame structure provides stable support for the pedal 5, preventing deformation of the pedal 5 and its connected sliding connection assembly 6.

[0052] For electrified vehicles, a battery pack is typically located beneath the floor 1 of the passenger compartment to provide the electrical power required to drive the vehicle. In the case of a retractable pedal 5, the pedal 5, retracted into the opening 8, is cleverly housed within the space between the floor 1 and the battery pack. The floor 1 forms the upper boundary, and the top of the battery pack's cover or casing forms the lower boundary, creating a thick interlayer space near the sill area. When fully retracted, the pedal 5's entire or most of its structure resides within this interlayer space. This layout fully utilizes the structural cavity created by the battery pack's placement beneath the floor 1, without additional encroachment on the passenger compartment's interior space, and without suspending the pedal 5 under the chassis, thus avoiding impacts on minimum ground clearance and passability. Simultaneously, this interlayer space, located inside the sill beam 3 and pedal mounting beam 4, together with the floor 1 and battery pack, forms an additional protective barrier, ensuring the pedal 5 is well protected from road debris, mud, and other external environmental erosion and impacts when retracted. Preferably, the interlayer space may also be provided with accessories such as actuators for locking and unlocking the pedal 5, so as to further integrate the functions of the whole vehicle and save space.

[0053] Finally, it should be noted that in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
